Description

An extended offshore environment restoration device

technical field

The invention belongs to the field of marine life development, and in particular relates to an extended offshore environment restoration device.

Background technique

In the marine biological industry, fish multiplication and seaweed multiplication are the mainstream directions at present. In marine fisheries, various fish gathering devices such as artificial reefs will be used to attract and protect fish schools. To achieve fish gathering; in terms of seaweed proliferation, at present, seaweed reefs are mainly used as units to establish seaweed farms with a certain area to provide a good basis for seaweed attachment and proliferation. However, in the prior art, it is inconvenient to put and set fish reefs and algae reefs. This is because most of the fish reefs need to sink to the bottom (sea bottom) or close to the bottom of the sea, but after the fish reefs are placed, the primary fish gathering effect is poor, and it is difficult to form a good micro-ecosystem on the bottom of the sea; algae reefs can provide more food for fish schools However, because many seaweeds (especially artificially propagated seaweeds, such as sargassum, sargassum, etc.) grow relatively fast near the sea surface (intertidal zone, within tens of meters under the sea, etc.), due to light exposure on the seabed The algae reefs are poor and grow slowly, so algae reefs are mostly set closer to the sea surface, but it is difficult to provide good protection for fish schools near the sea surface, so the best fish gathering effect cannot be achieved.

Contents of the invention

The present invention aims to overcome the above-mentioned deficiencies in the prior art, and provides an extended offshore environment restoration device that has a reasonable structure and multiple functions, provides food sources for fish schools, and achieves good protection effects.

In order to achieve the above object, the present invention adopts the following technical solutions:

An extended offshore environment restoration device, including a floating foundation and a sinking foundation, the floating foundation is provided with floating balls outside, the floating foundation is provided with an isolated upper chamber and a lower chamber, and the upper chamber of the floating foundation is provided with a For the winding drum of the rope, there are several expansion bases arranged in parallel in the vertical direction under the floating base, and the adjacent expansion bases are connected by ropes, and there are control expansion bases and floating bases one by one Separate disengagement mechanism, the disengagement mechanism includes a sliding positioning pin that runs through each expansion base and the side wall of the floating base and can slide into the floating base. The pins and the same water channels as the positioning pins, the upper part of the sinking foundation are provided with a number of seaweed cultivation bricks, the sinking foundation and the floating foundation are connected by ropes, the ropes run through the middle of each expansion foundation, and the sinking foundation is provided with external connections. The inner cavity of the inner cavity and several water-permeable layers located below the inner cavity and communicated with the inner cavity. When the fish reef is put into the seawater, the floating foundation floats close to the sea surface through its own buoyancy and the assistance of the floating ball. The sinking foundation is located under the floating foundation. Due to the action of the rope, the sinking foundation will not sink temporarily. The seaweed seedlings in the cultivation bricks are gradually developed and grown by being irradiated by light. At the same time, seawater enters the water channel to corrode the pins. After seawater corrodes the tip of the pin inserted into the positioning groove, the sliding positioning pin slides inward, and the expansion base at the bottom is out of position. The base descends along the rope, and the falling distance is limited by the rope between the extended base of the previous layer. Afterwards, with the corrosion of seawater, the expansion foundations fall in turn and are limited by the ropes. Finally, when all the expansion foundations are detached from the sliding positioning pins for positioning, the sinking foundations descend to the bottom of the sea, and the expansion foundations are distributed in various layers of seawater in turn. In this way, the seaweed seedlings are close to the seawater surface when they are in the growth stage, and the growth rate is fast, and they can continue to be replenished after a period of time. The expansion base is distributed in different depths of seawater, and the effect of repairing the seawater environment and gathering fish is excellent. The sinking base can eventually sink to the bottom of the sea, thereby protecting the fish school.

Preferably, the expansion base includes a support corresponding to the bottom of the floating base and a turret corresponding to the side of the floating base, the turret is rotatably connected to the support, and the turret can rotate to the outside of the support in a vertical position. Several seaweed cultivation bricks are arranged on the turret. The expansion base can cooperate with the floating base before it falls like this, which is convenient for transportation and delivery. After the expansion base falls, the turret can be opened relative to the support to increase the contact with seawater, facilitate the growth of algae, and improve the fish gathering effect.

As a preference, the lower chamber includes a lower chamber body and several float passages penetrating through the sidewall of the buoyant foundation, the float passage is provided with auxiliary floats that can move out of the buoyant foundation along the float passages, and the auxiliary floats are sealed and connected with the float passages , the lower chamber communicates with the float channel, the floating ball communicates with the lower chamber, and the floating ball is provided with a one-way inflation port. When the extended base falls completely and the sinking base falls to the bottom of the sea, the overall weight of the reef will increase due to the growth of seaweed, so it can be artificially inflated from the one-way inflation port to make the auxiliary float move outward, increasing the drainage volume of the floating base and thus When the buoyancy is improved and the auxiliary float moves outward, the overall size of the floating base becomes larger, which can further increase the scale of the micro-ecosystem of the fish reef.

Preferably, a vertical position locking mechanism is provided between the expansion bases, including a slide block that can slide in the bracket, a hinged push rod is provided between the slide block and the bottom of the turret, and a limit protrusion is provided on the sliding upper surface The support of the upper expansion base is provided with a positioning hole that matches the limit protrusion of the slider in the lower expansion base. In this way, when the expansion base is stacked in layers, the turret is restricted in a vertical state and cannot rotate outwards, so as to facilitate transportation and delivery, and when the expansion base is separated, the turret will open outwards, thereby providing more living space.

Preferably, the detachment mechanism further includes a deceleration wheel, which is arranged in the upper cavity, and a coaxial small runner is fixed on the bobbin, and the deceleration wheel and the deceleration small runner are connected by a transmission belt to reduce the speed. A coaxial small turntable is fixed on the wheel, and the sliding positioning pin is connected with the small turntable by an elastic rope. Through the action of the elastic rope, the sinking foundation can be restricted from falling too fast. At the same time, when the foundation sinks, it will act on the sliding positioning pin through the elastic rope, so that the sliding positioning pin and the pin fit closely, ensuring the seawater corrosion effect of the pin.

Preferably, a rotating plate is provided on the side of the floating base to cover the passage opening of the float, the upper end of the rotating plate is hinged to the outer surface of the floating base, and the auxiliary float pushes the rotating plate to rotate upward when moving outward. In this way, the turning plate is opened during the outward movement of the auxiliary float, and an extra space is formed between the turning plate and the auxiliary float, so as to provide a hiding space for small fish or young fish floating up to look for food.

Preferably, the water-through layers are arranged in parallel in the vertical direction, the water-through layers communicate with each other, the side walls of the sunken foundation are provided with side through holes communicating with the water-through layers, and the bottom of the sunken foundation is provided with support pipes. In this way, when the sinking foundation falls to the seabed, the sinking foundation will be supported by the support tube, and there will be a certain distance between the sinking foundation and the seabed, which can provide living space for crustaceans such as shrimps and crabs and molluscs such as shellfish on the seabed. The space of the reef is larger and the spatial structure of the water layer is more complex, which is suitable for fish of different types and sizes to avoid, making the fish reef ecosystem more abundant.

Preferably, shell fragments are provided on the upper surface of the floating foundation. After the surface is covered with shell fragments, the contact surface with seawater is increased, which provides a better attachment environment for plankton, and the foraging of seabed organisms becomes more convenient.

Preferably, the pin is made of nodular cast iron, the sliding positioning pin is made of stainless steel, and the contact area between the pin and the sliding positioning pin is smaller than the cross-sectional area of the sliding positioning pin. Ductile iron is subjected to electrochemical corrosion by seawater, and the corrosion rate is about 0.7mm per year. In addition, due to the different materials used for the pin and the sliding positioning pin, galvanic corrosion is formed between the two. The pin is an anode, and the sliding positioning pin is a cathode. The relatively large area of the cathode and anode accelerates the corrosion and dissolution of the anode, so that the corrosion rate of the pin can be greater than 2mm per year.

The beneficial effects of the present invention are: (1) It can supplement abundant food for marine fish at intervals, and the effect of gathering fish is good; (2) It can provide food sources for fish schools in different depths of water, forming a three-dimensional ecosystem; (3) After the submerged foundation falls to the seabed, it provides a living environment for seabed organisms, which has a good protection effect and helps to enrich biological species; (4) The floating foundation and the expansion foundation have the function of stretching, increasing the coverage area of seaweed and playing the role of expansion.

The water-permeable layers are arranged in parallel in the vertical direction and communicate with the inner cavity. At the same time, the water-permeable layers are also connected with each other. Support tube 1b. The upper part of the base is provided with some seaweed cultivation bricks 13 . A floating ball 7 is arranged outside the floating base, and the floating ball communicates with the lower cavity of the floating base through a vent pipe 6 .

As shown in Figure 2 and Figure 4, the expansion base includes a bracket 11b corresponding to the bottom of the floating base and a turret 11a corresponding to the side of the floating base, and several seaweed cultivation bricks are arranged on the turret. The turret is rotatably connected with the support, and the turret can rotate to the outside of the support in a vertical position. A vertical position locking mechanism is provided between the expansion bases, including a slide block 11d that can slide in the bracket, and a hinged push rod is provided between the slide block and the bottom of the turret. The upper surface of the slide is provided with a limit projection 11e, and the support of the upper expansion base is provided with a positioning hole 11f that matches the limit projection of the slide block in the lower expansion base. When the turret is in a vertical position, the limit projection It is just positioned in the positioning hole for limiting, preventing the turret from rotating outwards.

As shown in Figure 3, the disengagement mechanism includes a sliding positioning pin 16 that runs through each expansion base and the side wall of the floating base and can slide into the floating base. The pin 14 that the groove matches and the water channel 1101 that is the same as the positioning pin, is provided with a pin hole in the water channel, and is provided with a spring 15 acting on the pin in the pin hole. In addition, it also includes a speed reduction wheel 18, the speed reduction wheel is located in the upper cavity, the coaxial small runner 9 is fixed on the bobbin, the speed reduction wheel and the speed reduction small runner are connected by a transmission belt 20, and the coaxial small runner 9 is fixed on the speed reduction wheel. The small turntable 19 is connected by an elastic rope 17 between the sliding positioning pin and the small turntable. The pin is made of nodular cast iron, the sliding locating pin is made of stainless steel, and the contact area between the pin and the sliding locating pin is smaller than the cross-sectional area of the sliding locating pin. The diameter of the small runner is much smaller than that of the bobbin, and the diameter of the small turntable is also much smaller than that of the reduction wheel. After three decelerations between the bobbin and the small runner, the small runner and the reduction wheel, and the reduction wheel and the small turntable, the total reduction ratio If the setting is greater than 100:1, the elastic rope is in a loose state at the beginning. When the winding drum releases the rope, it is gradually tightened, so that the sliding positioning pin can fit the pin tightly, ensuring that the corrosion rate of the pin meets the expectation.

As shown in Figure 5, the lower cavity includes the lower cavity and a number of float passages 10c penetrating the side walls of the buoyant base. Auxiliary floats 4 that can move out of the buoyant base along the float passages are arranged in the buoyant passages.

In the actual use process, the initial state of the reef, as shown in Figure 1, the expansion base is stacked under the floating base, the turret of the expansion base is in a vertical state, and because the expansion base layers are stacked, the limit protrusion Cooperating with the positioning hole, the turret can always be kept in a vertical state without turning outwards. When the fish reef is put into the seawater, the floating base floats close to the sea surface through its own buoyancy and the assistance of the floating ball. The sinking base is located under the floating base, and the sinking base will not sink temporarily due to the action of the rope. The seaweed seedlings in the seaweed cultivation bricks on the upper part of the sinking foundation gradually develop and grow under the light irradiation, and at the same time, seawater enters into the water tank to corrode the pins. After seawater corrodes the tip of the pin inserted into the positioning groove, the sliding positioning pin slides inward under the pull of the elastic rope, and the expansion base at the bottom is out of position, and the sinking base and the expansion base descend together. The extended base descends along the rope, and the falling distance is limited by the rope between the extended base and the upper layer. The turret on the extension base rotates outward under the action of seawater flow, and the seaweed cultivation bricks arranged on the turret start to grow after the seaweed seedlings are irradiated by sunlight, thereby providing food sources for fish schools.

Afterwards, with the corrosion of seawater, the expansion bases fall one by one and are limited by the rope, and are distributed in each layer of seawater in turn. After all expansion bases are all separated from the positioning of the sliding positioning pins at last, the sliding positioning pins enter in the floating foundation, the elastic rope becomes slack, and the sinking base can descend to the seabed. In this way, the seaweed seedlings are close to the seawater surface when they are in the growth stage, and the growth rate is fast, and they can be supplemented to the deep seawater area after a period of time. The expansion base is distributed in different depths of seawater, and the effect of repairing the seawater environment and gathering fish is excellent. The sinking base can eventually sink to the bottom of the sea, thereby protecting the fish school.

When the extended base falls completely and the sinking base falls to the bottom of the sea, the overall weight of the reef will increase due to the growth of algae. At this time, it can be artificially inflated from the one-way inflation port to make the auxiliary float move outward, improving the drainage of the floating base. The volume improves the buoyancy. After the auxiliary float moves outward, the rotating plate is pushed upward to open, and the overall size of the floating foundation becomes larger, which can further increase the scale of the micro-ecosystem of the fish reef.
