DETAILED DESCRIPTION

[0038] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0039] Please also read Figures 1 to 12 , a breakwater for seaweed heat resistance and water retention provided by the present invention is now described. The breakwater for seaweed heat resistance and water retention is set in the waters around the shore and forms a protected water area 1 with the shore. The breakwater includes a main structure 2 and a plurality of sealing plates 3; the main structure 2 is provided with a plurality of first water-permeable holes 21 at intervals; each first water-permeable hole 21 penetrates the main structure 2 along the thickness direction; a plurality of sealing plates 3 are arranged on the inner side of the main structure 2 and close to the bottom thereof; each sealing plate 3 corresponds one-to-one to the first water-permeable hole 21 of the main structure 2 close to the bottom; wherein the diameter of the sealing plate 3 is larger than the diameter of the first water-permeable hole 21, and the top of the sealing plate 3 is hinged on the main structure 2; at low tide, the sealing plate 3 closes the first water-permeable hole 21 of the main structure 2 close to the bottom, so that the protected water area 1 has a preset liquid level at low tide.

[0040] The present invention provides a breakwater for seagrass heat resistance and water retention. Compared with the prior art, a plurality of first water-permeable holes 21 are arranged on the main structure 2, so as to play the role of wave breaking and allow seawater to enter the inside of the main structure 2 from the outside of the main structure 2; the sealing plate 3 on the main structure 2 opens the first water-permeable holes 21 under the impact of seawater, so that the seawater on the outside of the main structure 2 can flow into the inside; at low tide, the self-gravity of the sealing plate 3 is greater than the buoyancy, so the sealing plate 3 can close the first water-permeable holes 21, reduce the situation that the seawater on the inside of the main structure 2 flows into the outside of the main structure 2, and facilitate the maintenance of the seawater on the inside of the main structure 2 at a preset liquid level, thereby reducing the exposure of the seagrass bed to the air; through the above-mentioned arrangement of the present application, at low tide, it is possible to reduce the direct sunlight on the seagrass, reduce the death of seagrass, and improve the heat resistance of the seagrass at low tide.

[0041] In some embodiments, Figures 1 to 12 As shown, a row of second water-permeable holes 22 are provided near the bottom of the main structure 2, and each second water-permeable hole 22 is located between the two first water-permeable holes 21 in the upper layer; a sealing plate 3 is hinged on the inner side of the main structure 2 at the position of each second water-permeable hole 22.

[0042] It should be noted that by arranging a row of second water-permeable holes 22 near the bottom of the main structure 2, seawater can enter from the outside to the inside, reducing the impact of seawater. The longitudinal section of the main structure 2 is a trapezoidal structure, and the area of ​​the bottom of the main structure 2 is larger than the area of ​​the top of the main structure 2.

[0043] In some embodiments, Figures 1 to 12As shown, a detection device 4 is provided on the inner side of the main structure 2 at the position of each sealing plate 3, and each detection device 4 includes an indicator light 41 arranged on the top of the main structure 2, and a starting switch 42 electrically connected to the indicator light 41 is provided on the main structure 2. The detection device 4 also includes a starting structure connected to the starting switch 42 and the sealing plate 3; wherein, when the sealing plate 3 closes the first water permeable hole 21 and the sealing plate 3 closes the second water permeable hole 22, the starting structure controls the starting switch 42 to close, and the indicator light 41 emits a bright light.

[0044] It should be noted that by setting the detection device 4 on the top of the main structure 2, when the tide is low, the seawater outside the main structure 2 recedes, and the seawater inside the main structure 2 can maintain a preset liquid level under the blocking effect of the sealing plate 3, thereby reducing the exposure of the seagrass bed to the air. Since the seagrass bed is an inclined surface, and the height of the seagrass bed close to the shore is the highest, it is necessary to ensure that the liquid level at the highest position of the seagrass bed is maintained at a preset liquid level at low tide; specifically, at low tide, the liquid level at the highest position of the seagrass bed is maintained between 20 cm and 50 cm.

[0045] An indicator light 41 is set on the top of the main structure 2, and the starting switch 42 and the sealing plate 3 are connected through the starting structure. When the sealing plate 3 closes the water hole, the starting structure can close the starting switch 42, and then the indicator light 41 lights up; the staff can judge whether the sealing plate 3 closes the water hole by observing the indicator light 41 on the top of the main structure 2; when the water hole is stuck by debris, the sealing plate 3 cannot close the water hole, and the indicator light 41 will not light up at this time; therefore, at low tide, the staff can judge whether there is a water leakage according to the on and off of the indicator light 41.

[0046] In addition, a waterproof box is arranged near the top of the main structure 2, a battery is arranged in the waterproof box, and a solar panel is arranged outside the waterproof box. The solar panel generates electricity, which can save electricity.

[0047] In some embodiments, Figures 1 to 12 As shown, the start structure includes a cam 43, a connecting rod 44 and a limiting component 45; the cam 43 is connected to the rotating shaft of the sealing plate 3; the inner side of the main structure 2 has an avoidance groove 23 for the cam 43 to be screwed in; one end of the connecting rod 44 abuts against the cam 43, and the other end extends upward to the position of the start switch 42; when the sealing plate 3 is closed, the connecting rod 44 presses the start switch 42 to close the start switch 42; the limiting component 45 is connected to the main structure 2; the limiting component 45 has a through hole for sliding with the connecting rod 44. The top of the connecting rod 44 is connected to an abutment plate 46. When the sealing plate 3 is closed, the connecting rod 44 slides upward, and the abutment plate 46 presses the start switch 42; when the sealing plate 3 is opened, the connecting rod 44 slides downward, and the abutment plate 46 is separated from the start switch 42; the start switch 42 is a waterproof switch.

[0048] It should be noted that the limiting component 45 is fixed on the main structure 2, and the connecting rod 44 slides with the limiting component 45, which can guide and limit the connecting rod 44; when the sealing plate 3 opens the water permeable hole under the impact of seawater, the cam 43 can be screwed into the avoidance groove 23 of the main structure 2. At this time, the connecting rod 44 moves downward, so that the abutment plate 46 is separated from the starting switch 42; after the abutment plate 46 is separated from the starting switch 42, the starting switch 42 is automatically reset and is in a disconnected state, so the indicator light 41 stops emitting light.

[0049] At low tide, the sealing plate 3 can close the water permeable hole under the action of its own gravity. At this time, the cam 43 is rotated out of the avoidance groove 23 and drives the connecting rod 44 to slide upward. At this time, the abutment plate 46 on the connecting rod 44 can press the starting switch 42. The starting switch 42 is in a closed state and the indicator light 41 emits a light.

[0050] In some embodiments, Figures 1 to 12 As shown, the starting structure further includes a counterweight component 47 , and the counterweight component 47 is connected to the connecting rod 44 .

[0051] It should be noted that, by providing the counterweight component 47 on the connecting rod 44 , the lower end of the connecting rod 44 can be brought into contact with the cam 43 , so that the connecting rod 44 can be moved up and down by the rotation of the cam 43 .

[0052] In some embodiments, Figures 1 to 12 As shown, a protrusion 31 is connected to the top of the sealing plate 3, and a rotating shaft 32 is provided on both sides of the protrusion 31; a first hinge seat 24 is connected to the main structure 2, and the first hinge seat 24 has a rotating groove 241 for inserting the rotating shaft 32, and the bottom wall of the rotating groove 241 is an arc surface; a second hinge seat 25 is detachably connected to the first hinge seat 24, and the second hinge seat 25 has an inserting portion 251 that is plugged into the rotating groove 241, and the end of the inserting portion 251 is an arc surface; the arc surface of the inserting portion 251 and the arc surface of the rotating groove 241 are both used to contact the outer peripheral wall of the rotating shaft 32.

[0053] It should be noted that when installing the sealing plate 3, the second hinge seat 25 is first removed from the first hinge seat 24, and then the shaft 32 on the protrusion 31 is inserted into the rotation groove 241 on the first hinge seat 24, and then the second hinge seat 25 is installed on the first hinge seat 24. At this time, the arc surface of the plug-in portion 251 and the arc surface of the rotation groove 241 can limit the shaft 32, so that the shaft 32 can only rotate in the rotation groove 241, reducing the radial movement of the shaft 32 along the rotation groove 241.

[0054] In some embodiments, Figures 1 to 12As shown, the second hinge seat 25 and the first hinge seat 24 are connected by bolts, the first hinge seat 24 has a threaded hole, and the second hinge seat 25 has a countersunk hole aligned with the threaded hole; when the bolt passes through the countersunk hole and is connected to the threaded hole of the first hinge seat 24, a protective cap 26 is inserted and matched in the countersunk hole. The bolt is a corrosion-resistant bolt, which is a prior art and will not be described in detail here.

[0055] It should be noted that after the second hinged seat 25 is fixed to the first hinged seat 24 by bolts, the head of the bolt is located in the countersunk hole of the second hinged seat 25. At this time, the protective cap 26 is plugged into the countersunk hole to protect the head of the bolt, reduce the seawater contacting the bolt head, and delay the corrosion of the bolt.

[0056] In some embodiments, Figures 1 to 12 As shown, a control module and a wireless transceiver module are connected to the top of the main structure 2, and the control module is electrically connected to the wireless transceiver module; a water receiving box 5 is connected to the outer side of the main structure 2 at a position corresponding to the sealing plate 3, and the water receiving box 5 is an arc-shaped structure and is located below the water permeable hole; a drainage pipe 51 is connected to the lowest point of the water receiving box 5, and a flow meter is provided on the drainage pipe 51, and the flow meter is electrically connected to the control module.

[0057] It should be noted that the control module and the wireless transceiver module are prior art and will not be described in detail here. By setting a water receiving box 5 at the position of the water permeable hole outside the main structure 2, and setting a drainage pipe 51 and a flow meter on the water receiving box 5; at low tide, if the sealing plate 3 cannot close the water permeable hole, the indicator light 41 on the top of the main structure 2 will not light up, and the seawater inside the main structure 2 will flow out from the water permeable hole. At this time, the water receiving box 5 can receive seawater. During the process of the seawater in the water receiving box 5 flowing out from the drainage pipe 51, the flow meter will have a flow value. At this time, the control module can send the flow value to the terminal device of the staff through the wireless transceiver module to remind the staff of the leakage, so as to facilitate the staff to repair in time.

[0058] Specifically, a control box is arranged on the outside of the main structure 2 near the top, and the control module and the wireless transceiver module are both arranged in the control box; the outside of the main structure 2 refers to the side opposite to the sealing plate 3; the control module and the wireless transceiver module in the control box are powered by the battery in the waterproof box, and the specific cable connection will not be repeated here, as the waterproof box has been mentioned in the above content.

[0059] Control process: at low tide, if the sealing plate 3 is stuck or other faults occur, the sealing plate 3 cannot close the water permeable hole. At this time, the seawater on the inside of the main structure 2 will pass through the water permeable hole. After the seawater flows to the outside, it enters the water receiving box 5 and finally flows out from the drainage pipe 51; when flow appears in the drainage pipe 51, the flow meter will generate a flow signal, and the flow meter will transmit the flow signal to the control module. The control module receives the flow signal and generates a control signal. The control signal is transmitted to the wireless transceiver module, and the wireless transceiver module transmits the information to the terminal device. At this time, the staff can know the abnormal situation.

[0060] It should be noted that when the indicator light is not on, the control module receives the flow signal generated by the flow meter and sends it to the terminal device through the wireless transceiver module, which can serve the purpose of double reminder and thus reduce the situation of continuous water leakage due to the staff not being able to see the indicator light failure.

[0061] By arranging a water receiving box 5 on the outside of the main structure 2, and the water receiving box 5 is located below the water permeable hole, the water receiving box 5 does not affect the water permeability of the water permeable hole, and when the tide is low, the water receiving box 5 can also detect whether there is seawater flowing out from the inside of the main structure 2.

[0062] In addition, if Figures 1 to 12 As shown, the main structure in the present application can be an integral cast structure or a module installation structure; when the main structure is a module installation structure, the height of the main structure is 1 meter, and after the foundation is constructed at a preset position on the seabed, it is assembled through a number of splicing components 6. Specifically, this embodiment focuses on the splicing components 6, and other structures arranged on the breakwater are not repeated in this embodiment. One side of each splicing component 6 is a first plug-in protrusion 61, and the other side is a first plug-in groove 62; the bottom of each splicing component 6 is a second plug-in protrusion 63, and the top of each splicing component 6 is a second plug-in groove 64. When splicing, the first plug-in protrusion 61 of the splicing component 6 is plugged into and matched with the first plug-in groove 62 of another splicing component 6; the second plug-in protrusion 63 at the bottom of the splicing component 6 is plugged into and matched with the second plug-in groove 64 of the splicing component 6 of the next layer. Through the above-mentioned arrangement of the present application, the splicing construction of the breakwater can be realized, which can transform the local marine environment in the short term and promote the survival of seagrass beds and various organisms therein; after the transformed sea area is basically stabilized, the breakwater can be dismantled.

[0063] Anti-corrosion bolts 65 are preset on two adjacent splicing parts 6. After the two adjacent splicing parts 6 are spliced ​​together, the two anti-corrosion bolts 65 are connected by a connecting plate 66, and the anti-corrosion nut 67 is threadedly matched with the anti-corrosion bolt 65 to strengthen the connection between the two adjacent splicing parts and increase the overall stability of the breakwater.

[0064] The working principle of the present application is as follows: at high tide, the seawater on the outside of the main structure 2 can pass through the water-permeable holes and enter the inside of the main structure 2. The water-permeable holes on the main structure 2 can play the role of wave breaking, reducing the impact of waves on the seaweed inside the main structure 2; in addition, the seawater passes through the water-permeable holes and pushes the sealing plate 3 to rotate around the hinge axis, which consumes the energy of the seawater, further reducing the impact of the seawater on the inside of the main structure 2.

[0065] At low tide, the seawater inside the main structure 2 will pass through the water permeable holes and eventually flow to the outside of the main structure 2. Since the sealing plate 3 closes the water permeable holes near the bottom of the main structure 2, the sea surface inside the main structure 2 is maintained at a preset height, which can reduce the exposure of the seagrass bed to the air and thus reduce the death of seagrass.

[0066] At low tide, the sealing plate 3 closes the water permeable hole, and the indicator light emits a light; when the sealing plate 3 is stuck, the sealing plate 3 cannot close the water permeable hole, and the indicator light at this time is not on, and seawater continues to flow through the water permeable hole; when the seawater passes through the water permeable hole, the seawater will enter the water receiving box 5 and eventually flow out from the drainage tube 51; at this time, the flow meter on the drainage tube 51 will generate a flow signal, and the flow signal is transmitted to the control module, and the control module sends a control signal to the wireless transceiver module. At this time, the wireless transceiver module sends the flow signal to the terminal device to facilitate the staff to know the abnormal situation.

[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
