All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The near space tethered float system and dispensing method of the present invention is described below in conjunction with fig. 1-4.
As shown in fig. 1, in an embodiment of the invention, the near space tethered buoyancy system comprises an aerostat 1, a zero pressure balloon 2, a pod 4 and a drum 5. The aerostat 1, the zero pressure balloon 2 and the pod 4 are connected in sequence, and the pod 4 is connected with the roller 5 through the mooring rope 3. The drum 5 rises together with the aerostat 1 when the aerostat 1 is issued. In the prior art, the pod 4 is connected with a winch 6 on the ground through the mooring rope 3, when the aerostat 1 ascends to the windward region, the balloon of the aerostat 1 is not fully inflated and formed, the mooring rope 3 drags the aerostat 1 to form a balloon, so that the balloon of the aerostat 1 is extremely easy to damage or fracture the mooring rope 3, while in the embodiment, the mooring rope 3 is not connected with the winch 6 on the ground, and the balloon of the aerostat 1 is not fully inflated and formed when the aerostat 1 ascends to the windward region, but the balloon is not formed because the mooring rope 3 is not connected with the ground winch 6, so that the risk of damaging the balloon of the aerostat 1 or the mooring rope 3 is avoided.
According to the adjacent space mooring floating system provided by the embodiment of the invention, the mooring rope is connected with the roller, and is not connected with the ground in the rising process of the aerostat, so that the aerostat is not enabled to form a wind pocket, the damage to the aerostat bag body or the mooring rope is avoided, the aerostat can be safely released to the adjacent space, and technical support is provided for the development and utilization of the adjacent space.
As shown in fig. 1, in the embodiment of the present invention, the aerostat 1 includes a first airbag 11 and a second airbag 12, the first airbag 11 is connected with the second airbag 12, and the second airbag 12 is connected with the pod 4. Wherein, a small amount of air is filled in the first air bag 11, a certain amount of helium is filled in the second air bag 12, and the air pressure in the first air bag 11 is basically equal to the air pressure in the second air bag 12. The first air bag 11 is connected with a first air pipe, and a first control component is arranged on the first air pipe and used for controlling the on-off of the first air pipe. In this embodiment, the first control assembly includes a first valve 111 and a first fan, and when the first control assembly is opened, the first valve 111 and the first fan are simultaneously opened to exhaust air in the first air bag 11 or suck external air into the first air bag 11. In this embodiment, the blower may rotate forward or reverse to achieve air intake or exhaust.
Before the aerostat 1 is released, the first air bag 11 and the second air bag 12 are not inflated and formed when on the ground because the ground air density is more than ten times that of the near space air density. During the release, the first and second airbags 11 and 12 are gradually inflated until the first and second airbags 11 and 12 are completely inflated, while the internal air pressure is greater than the external air pressure. A pressure sensor is provided in the first air bag 11 or the second air bag 12, and the pressure sensor is used for detecting the pressure of the air in the first air bag 11 or the second air bag 12 in real time. The pod 4 is internally provided with a controller, after the first air bag 11 and the second air bag 12 are fully inflated, the pressure sensor sends pressure data detected in real time to the controller, the controller calculates the difference value between the pressure of the air in the aerostat 1 and the atmospheric pressure in real time, when the difference value exceeds a first preset value, the controller controls the first control component to be started, and the first air bag 11 is exhausted outwards so as to reduce the internal air pressure. When the difference between the gas pressure and the atmospheric pressure is reduced to be within the threshold range, the controller controls the first valve 111 and the first fan to stop operating. The aerostat 1 continues to rise, and during the rising process of the aerostat 1, the controller always controls the first valve 111 and the first fan to be started or closed according to the pressure difference value, so that the pressure difference between the air pressure in the aerostat 1 and the external atmospheric pressure is always within the threshold value range.
The upper part of the zero-pressure balloon 2 is connected with the second air bag 12, the lower part of the zero-pressure balloon 2 is connected with the nacelle 4, and helium is filled in the zero-pressure balloon 2. Before the aerostat 1 is released, helium gas with target mass is filled into the zero-pressure balloon 2, and at this time, the zero-pressure balloon 2 is not inflated and formed. When the aerostat 1 is released, after the first and second airbags 11 and 12 are fully inflated, the aerostat 1 continues to rise, the atmospheric density and the atmospheric pressure further decrease, and the zero-pressure balloon 2 is fully inflated.
In the embodiment of the present invention, the zero-pressure balloon 2 is connected with the exhaust pipe 21, and after the zero-pressure balloon 2 is completely inflated, the internal air pressure is equal to the external air pressure, and the internal-external pressure difference is zero, so that the zero-pressure balloon is used. The specific working principle is that in the rising process of the zero-pressure balloon 2, the internal air pressure is larger than the external atmospheric pressure, the zero-pressure balloon 2 is gradually inflated, the external atmospheric pressure is gradually reduced along with the increase of the rising height, when the zero-pressure balloon 2 is completely inflated, the internal redundant helium is discharged by the exhaust pipe 21, so that the internal air pressure of the zero-pressure balloon 2 is equal to the external atmospheric pressure, and the pressure difference of the two is zero.
After the zero-pressure balloon 2 is fully inflated, the aerostat 1 and the zero-pressure balloon 2 continue to ascend until the total buoyancy of the tethered floating system in the adjacent space is equal to the total weight, and the aerostat 1 and the zero-pressure balloon 2 do not move up and down any more and are in a floating state.
In this embodiment, the lower part of the second airbag 12 is connected with the zero-pressure balloon 2, and helium is filled in the zero-pressure balloon 2, so that the helium can provide buoyancy for the mooring and floating system in the adjacent space, and the aerostat 1 has enough net buoyancy to rise to the adjacent space.
As shown in fig. 1 and 2, in an embodiment of the invention, the nacelle 4 is connected to the drum 5 by a first connection 71 in addition to the nacelle 4 being connected to the drum 5 by a mooring line 3. The first connector 71 is provided with a first cutter 711, and the controller controls the first cutter 711 to cut off the first connector 71 so that the drum 5 falls to the ground when the aerostat 1 and the zero-pressure balloon 2 are in a floating state.
Further, the near space tethered buoyancy system further comprises a second connector 72, a third connector 73, a fourth connector 74, a second cutter 721 and a third cutter 731. The upper part of the zero-pressure balloon 2 is connected to the second envelope 12 by a second connection 72, the lower part of the zero-pressure balloon 2 is connected to the pod 4 by a third connection 73, and the second envelope 12 is connected to the pod 4 by a fourth connection 74. The second cutter 721 is disposed on the second link 72 for cutting the second link 72, and the third cutter 731 is disposed on the third link 73 for cutting the third link 73. Alternatively, in an embodiment of the present invention, the first, second, third and fourth connection members 71, 72, 73, 74 may each be a rope to facilitate the cutting of the cutter.
As shown in fig. 3, after the first link 71 is cut, the drum 5 falls. In the embodiment of the invention, a locator is arranged in the nacelle 4, the locator is used for acquiring the position of the roller 5 and transmitting the position information to the ground, and a ground operator can find the roller 5 according to the position information transmitted by the locator.
As shown in fig. 2, in the embodiment of the present invention, the drum 5 includes a drum body 51, a shutter 52, a magnetic powder clutch, and a rotating arm 53. One end of the mooring line 3 is wound around the drum body 51 and the other end is connected to the nacelle 4. Baffles 52 are arranged on two sides of the roller body 51, and a fixed seat 54 is arranged on each baffle 52. The drum body 51 is internally provided with a magnetic powder clutch, an output shaft 55 of the magnetic powder clutch penetrates through the baffle plate 52 and the fixed seat 54 to be in rotary connection with the rotary arm 53, the rotary arm 53 is provided with a through hole, and the mooring rope 3 penetrates through the through hole to be connected with the nacelle 4. The magnetic powder clutch can drive the roller body 51 to rotate when rotating, and the rotating speed of the roller body 51 can be adjusted by controlling the output torque of the output shaft 55 of the magnetic powder clutch, so as to adjust the descending speed of the roller 5. When the drum 5 is at a distance from the sea level, the torque of the output shaft 55 of the magnetic particle clutch is increased to reduce the descent speed of the drum 5. The operator finds the roller 5 according to the position information of the roller 5 sent by the locator, and lowers the roller 5 to the ship, the winch 6 is arranged on the ship, the mooring rope 3 is connected with the winch 6, and the height of the aerostat 1 can be adjusted by winding and unwinding the mooring rope 3.
As shown in fig. 1, the second air bag 12 is connected with a second air pipe, a second control component is arranged on the second air pipe, and the zero-pressure balloon 2 is communicated with the second air pipe through a third air pipe. Specifically, the second control assembly comprises a second valve 121 and a second fan 122, and after the second valve 121 and the second fan 122 are opened, helium in the zero-pressure balloon 2 can be discharged into the second envelope 12.
Specifically, after the mooring line 3 is connected to the winch 6, the height of the aerostat 1 is lowered as the mooring line is retracted, the atmospheric density and the atmospheric pressure are increased as the height of the aerostat 1 is gradually lowered, the pressure difference between the inside and the outside of the aerostat 1 is gradually reduced, and when the pressure difference between the inside and the outside of the aerostat 1 is equal to zero. The controller controls the second valve 121 and the second fan 122 to be opened to discharge helium gas in the zero-pressure balloon 2 into the second envelope 12, and continues to retract the rope until the height of the aerostat 1 is reduced to the target height. The pressure sensor detects the pressure of the gas in the aerostat 1 in real time, and when the difference between the pressure of the gas and the external atmospheric pressure is greater than a second preset value, the second valve 121 and the second fan 122 are controlled to be closed.
As shown in fig. 4, after the second valve 121 and the second fan 122 are closed, the controller controls the second cutter 721 to be operated, cuts off the second connection member 72, and the zero-pressure balloon 2 is moved downward by the wind force. The controller controls the third cutter 731 to act to cut off the third connecting member 73, and the zero-pressure balloon 2 is flown away by the wind field.
In this embodiment, the height of the aerostat 1 can be adjusted by controlling the winch 6 to wind and unwind the rope, thereby causing the aerostat 1 to be airborne at the target height in the near space.
In this embodiment, the aerostat 1 is an overpressure aerostat, and a certain pressure difference exists between the air pressure inside the aerostat 1 and the external atmospheric pressure all the time, and the pressure difference is always within a threshold range. When the aerostat 1 descends to the target height and is in the space near the space, the pressure difference adjusting method comprises the following steps of controlling the first valve 111 and the first fan to be opened when the pressure difference is smaller than a third preset value, filling outside air into the first air bag 11 to increase the air pressure in the first air bag 11 and further increase the pressure difference, and controlling the first valve 111 and the first fan to be opened when the pressure difference is larger than the third preset value, discharging air in the first air bag 11 to reduce the air pressure in the first air bag 11 and further reduce the pressure difference.
Further, in this embodiment, when the internal air pressure of the aerostat 1 is much greater than the external air pressure, the aerostat 1 is rapidly inflated, which causes the first air bag 11 and the second air bag 12 to explode, and when the external air pressure is much greater than the internal air pressure of the aerostat 1, the first air bag 11 and the second air bag 12 are contracted, thereby forming a wind pocket under the action of the mooring rope 3, based on which the air pressure inside the aerostat 1 should be adjusted in real time during the releasing process of the aerostat 1, so that the internal and external pressure difference of the aerostat 1 is within the threshold range, and the aerostat 1 is always in a completely inflated state.
It should be noted that, in the above embodiment, the first preset value, the second preset value and the third preset value may be flexibly set according to specific use conditions, and the three values may be equal or unequal.
The embodiment of the invention also provides a release method of the near space mooring floating system, which comprises the following steps:
Step 01, filling a certain amount of air into the first air bag 11, filling helium with target mass into the second air bag 12 and the zero-pressure balloon 2, step 02, dispensing the aerostat 1 and the zero-pressure balloon 2, step 03, acquiring the difference between the air pressure in the aerostat 1 and the atmospheric pressure in real time after the first air bag 11 and the second air bag 12 are fully inflated, controlling the first control component to be opened when the difference exceeds a first preset value, discharging the air in the first air bag 11 until the difference is within a threshold value range, controlling the first control component to be closed, and continuously adjusting the pressure difference inside and outside the aerostat 1 in the rising process of the aerostat 1 and the zero-pressure balloon 2, wherein the aerostat 1 and the zero-pressure balloon 2 are in a floating state after the zero-pressure balloon 2 is fully inflated.
Specifically, before the aerostat 1 is released, the first air bag 11 and the second air bag 12 are not yet inflated and formed while on the ground, because the ground air density is more than ten times the near space air density. During the release, the first and second airbags 11 and 12 are gradually inflated until the first and second airbags 11 and 12 are completely inflated, while the internal air pressure is greater than the external air pressure. After the first and second airbags 11 and 12 are fully inflated, the pressure sensor sends the pressure data detected in real time to the controller, the controller calculates the difference between the gas pressure and the atmospheric pressure in real time, and when the difference exceeds a first preset value, the controller controls the first control component to be opened, and the first airbag 11 is exhausted outwards to reduce the internal air pressure. When the difference between the gas pressure and the atmospheric pressure is reduced to be within the threshold range, the controller controls the first valve 111 and the first fan to stop operating. The aerostat 1 continues to rise, and during the rising process of the aerostat 1, the controller always controls the first valve 111 and the first fan to be started or closed according to the pressure difference value, so that the pressure difference between the air pressure in the aerostat 1 and the external atmospheric pressure is always within the threshold value range.
After the first and second balloons 11, 12 are fully inflated, the aerostat 1 continues to rise and the atmospheric density and pressure are further reduced, with the zero-pressure balloon 2 being fully inflated. After the zero-pressure balloon 2 is fully inflated, the aerostat 1 and the zero-pressure balloon 2 continue to ascend until the total buoyancy of the tethered floating system in the adjacent space is equal to the total weight, and the aerostat 1 and the zero-pressure balloon 2 do not move up and down any more and are in a floating state.
According to the issuing method provided by the embodiment of the invention, the mooring rope is not connected with the ground in the ascending process of the aerostat, so that the aerostat is not enabled to form a wind pocket, the damage to the aerostat bag body or the mooring rope is avoided, the aerostat can be safely issued to the nearby space, and technical support is provided for the development and utilization of the nearby space.
When the aerostat 1 and the zero pressure balloon 2 are in a floating state, the first cutter 711 is controlled to cut off the first connection member 71 so that the drum 5 falls. When the drum 5 approaches the sea level, the torque of the output shaft 55 of the magnetic particle clutch is increased to reduce the descent speed of the drum 5. The operator finds the drum 5 based on the positional information of the drum 5 sent from the locator, and drops the drum 5 on the ship.
After the drum 5 has been lowered onto the vessel, the mooring line 3 is connected to a winch 6 on the vessel, and the winch 6 can pull the aerostat 1 down when the line is reeled in. During the descent of the aerostat 1, as the height of the aerostat 1 gradually decreases, the atmospheric density and the atmospheric pressure increase, the pressure difference between the inside and outside of the aerostat 1 gradually decreases, and when the pressure difference between the inside and outside of the aerostat 1 is equal to zero. The controller controls the second valve 121 and the second fan 122 to be opened so as to discharge helium gas in the zero-pressure balloon 2 into the second airbag 12 until the internal-external pressure difference of the aerostat 1 is greater than a second preset value. The rope is continuously retracted until the height of the aerostat 1 is reduced to the target height.
After the altitude of the aerostat 1 is lowered to the target altitude, the controller controls the second cutter 721 to operate, cuts off the second connector 72, and the zero-pressure balloon 2 is moved downward by the wind force. The controller controls the third cutter 731 to act to cut off the third connecting member 73, and the zero-pressure balloon 2 is flown away by the wind field.
Further, in the embodiment of the invention, the dispensing method further comprises controlling the first valve 111 and the first fan to be opened when the air pressure inside the aerostat 1 is lower than a third preset value when the aerostat 1 is lowered to a target height and the air pressure in the vicinity is resident, filling outside air into the first air bag 11 to increase the air pressure inside the first air bag 11 so as to increase the pressure difference between the inside and the outside of the aerostat 1 and further enable the difference to be within a threshold range, and controlling the first valve 111 and the first fan to be opened when the air pressure inside the aerostat 1 is higher than the third preset value and discharging the air inside the first air bag 11 so as to reduce the air pressure inside the first air bag 11 and further enable the pressure difference between the inside and the outside of the aerostat 1 to be within the threshold range. Meanwhile, the aerostat 1 always works at the target height by winding and unwinding the mooring rope.
