Pump-jet submersible wearable on limbs

technical field

The utility model relates to the technical field of submersibles, in particular to a pump jet submersible which can be worn on limbs.

As a healthy way of exercise, diving has many benefits such as decompression and anti-cancer, promoting blood circulation, developing muscles of the whole body, improving diver's strength and speed to achieve body shaping and plasticity. Now, more and more coastal cities have set up scenic diving projects, and divers can go into the water to experience diving after a short period of training. But the fact is that after tourists go into the water, they cannot control themselves at all, and they still need the protection of professionals to achieve the purpose of safe play.

Detailed ways

The utility model will be described in more detail below with reference to the accompanying drawings, but not as a limitation to the utility model.

As shown in FIGS. 1-4 , the pump-jet submersible wearable on the limbs includes a control device 9 , a pump-jet propulsion device and an adjustable arm protection device 7 . The control device 9 is fixedly connected with the oxygen cylinder 10 through the first connecting piece 8, and the control device 9 includes a housing with a streamlined sealing structure, a controller disposed in the housing, a battery, a gyroscope, and a device disposed on the housing. A sensor and an image acquisition device, the gyroscope, the sensor and the image acquisition device are electrically connected with the controller and the battery. The sensors include a temperature sensor for detecting water temperature, a pressure sensor for detecting water pressure and a photosensitive sensor for detecting light intensity. The pump-jet propulsion device is set as a bullet-shaped structure with the bottom protruding outwards, including a closed chamber 5 and a water pump, and the closed chamber 5 is provided with a motor electrically connected to the controller and the battery, an electric regulator and a steering gear . The water pump includes a pump body 3, a plurality of water inlets 4 arranged at intervals on the side wall of the pump body 3, and a water outlet 4 arranged at the bottom of the pump body 3, the pump body 3 is provided with an impeller 1, the The impeller 1 is connected with the output end of the motor through a rotating shaft. The adjustable guard arm 7 device is set as a hollow tubular structure with successively decreasing diameters, which is connected with the pump-jet propulsion device through the second connecting piece 6 . The inner layer of the adjustable arm protection device is a waterproof nylon Velcro, which can be adjusted according to the thickness of the diver's arm to ensure that the pump jet propulsion device is tightly fixed to the human forearm, and the Velcro and the adjustable arm protection shell are filled Elastic materials such as sponges enhance the comfort of use.

In this embodiment, two control devices 9 are arranged symmetrically to each other, and four pump-jet propulsion devices are arranged, which are respectively fixed to diver's limbs through adjustable guard arms 7 .

It also includes a safety airbag and a lighting lamp, the safety airbag is fixed on the oxygen cylinder 10 and connected with the oxygen cylinder 10; the lighting lamp is arranged on the top of the pump jet propulsion device and connected with the controller.

It also includes a remote controller, which is wirelessly connected with the controller to control the operation of the pump-jet propulsion device. It also includes a watch-shaped smart display device 11, the smart display device 11 is provided with a wireless receiver, and the wireless receiver is wirelessly connected to the controller. The smart display device 11 can be worn on the diver's wrist, and the screen can display information such as temperature, depth, water pressure, elapsed time of diving, and remaining power in the water area where the diver is located.

It also includes a control handle, the control handle is provided with control buttons, and the control buttons are wirelessly connected with the controller. The control handle is set to a "7"-shaped structure, and the horizontal direction of the control handle is sequentially arranged as an emergency button 12, a speed control button 13 and a direction adjustment button 14 from left to right; The number of recessed finger placement parts 15 is arranged in order from top to bottom in four.

The controller is provided with a remote control signal receiving unit wirelessly connected with the remote controller, an emergency signal receiving unit wirelessly connected with the control handle and a wireless transmission unit wirelessly connected with the display device.

In the process of use, the diver presses the corresponding button in the control handle to generate a signal and send it back to the controller to realize the speed regulation of the motor and the steering of the steering gear. The diver can only change the propulsion of the pump jet by not moving itself. The water spraying direction of the device realizes the change of its own movement direction.

The emergency button on the handle, when the diver is in a dangerous or emergency situation, the diver presses the emergency button to generate a signal and send it back to the controller. The controller controls the oxygen cylinder to inflate the airbag and brings the diver back to the surface . In addition, the mounted pressure sensor will monitor the water pressure in real time. When the water pressure reaches the threshold set in advance, it will send a signal to the controller. The controller will inflate the airbag by controlling the oxygen cylinder and bring the diver back to the surface. .

The submersible of the utility model, when the light is weak, automatically turns on the light to illuminate the diver. The principle is: the photosensitive sensor installed on the control device detects the light changes around the diver. When the light becomes dark, it can send a signal to the controller.

The submersible of the utility model can automatically maintain the diver's balance. The principle is: the gyroscope installed in the control device can detect the current position of the human body (whether it is tilted left or right), and transmit the signal to the controller. After the signal is processed by the controller, it is sent to the motor in the pump jet propulsion device to adjust the water spray of the pump jet propulsion device. speed to achieve a state of body balance.

Steps to use: Divers need to carry the control device on their back, wear adjustable arm guards connected to the pump jet propulsion device on their limbs, and can select the mode before entering the water.

The pump jet submersible worn on the limbs has two modes to choose from: shallow diving with remote control, shallow deep diving without remote control. The remote control unit in the remote control mode is composed of a wireless transmission unit connected to the controller and a remote control held by people on the shore. The wireless transmission unit can change the motor speed and rudder in the pump jet propulsion device by receiving the wireless signal transmitted by the remote control. By adjusting the angle of the diver, you can control the diver's speed and direction, and adjust the diver's route. In non-remote control mode: 1. The diver can adjust the direction of limbs independently, change the diving direction, and press the corresponding button on the handle to adjust the speed; 2. Use the above speed control handle to adjust the motor speed and steering angle. Both methods can realize the adjustment of the diver's route.

In addition, during use, divers can selectively turn off the pump jet propulsion device or reduce its water jet speed. The reason is: when divers need to use their hands for some activities (such as shooting, sampling and other scientific research activities or entertainment activities) , to prevent the water spraying of the pump jet propulsion device from interfering with the diver's activities. When the pump jet propulsion device of the arms is turned off, the pump jet propulsion device of the legs can still assist people in labor-saving diving, achieving the purpose of making diving movements flexible and convenient .

The embodiments of the utility model described above do not constitute a limitation to the protection scope of the utility model. Any modifications, equivalent replacements and improvements made within the spirit and principle of the utility model shall be included in the protection scope of the claims of the utility model.
