Description

Technical Field

[0001] This invention relates to the field of artificial reef technology, specifically to an artificial reef and a method for deploying a combined artificial reef. Background Technology

[0002] Artificial reefs are man-made structures placed in the sea to improve the marine ecological environment and provide a place for fish and other marine life to reproduce, grow, forage, and shelter from predators, thereby protecting and increasing fishery resources and improving catches.

[0003] Chinese patent CN113179985B discloses a tower-type artificial reef for raising and releasing fry in marine ranches and a cultivation method thereon. By using net frames with different mesh sizes in different tower layers of the artificial reef, fish fry and juvenile fish of different sizes can be protected. However, in marine ranches, seaweed and shellfish can climb and grow on the net frames. As the artificial reef is used for a longer period of time, seaweed and shellfish will gradually clog the mesh, and fish excrement will also clog the mesh. Even if the net frame is pulled to clean it, it is difficult to effectively remove the impurities clogging the mesh because seaweed and excrement can adhere to the gaps in the mesh. As a result, fish will gradually be unable to pass through the net frame. In addition, it is also difficult to pull the net frame to clean it underwater. Summary of the Invention

One end of the lifting plate is rotatably connected to the lower surface of the lifting pressure seat, and the other end of the lifting plate is rotatably connected to one end of the sliding plate. The fixed shaft is fixedly installed at the other end of the sliding plate. One end of the rotating plate is fixedly connected to the rotating shaft, and the other end of the rotating plate has a sliding hole. The fixed shaft is slidably connected to two adjacent sliding holes. The number of rotating shafts is twice the number of sliding plates. The two ends of the support spring are fixedly connected to the inner bottom wall of the base and the lower surface of the lifting pressure seat, respectively.

[0022] The crane cable is lowered to slowly place the artificial reef into the water, so that the lower surface of the base contacts the bottom silt after the artificial reef sinks into the water.

[0023] After the artificial reef is placed, cut off the excess rope, leaving only the length of the rope that can extend to the water surface, and attach the buoy to the other end of the rope.

[0024] (III) Beneficial Effects

[0025] Compared with the prior art, the present invention provides an artificial reef and a method for deploying a combined artificial reef, which has the following beneficial effects:

[0026] 1. This artificial reef, consisting of an outer reef, an inner reef, and intercepting rods, forms a three-layered reef chamber for the growth of fish fry and juveniles of different sizes. The inner reef can move up and down inside the outer reef, driving push plates and inserting rods to clean the access channels of the outer and inner reefs. Simultaneously, as the inner reef moves, the lifting pressure seat drives the intercepting blades to rotate, preventing algae, shellfish, and other organisms from multiplying and growing between the access channels of the outer and inner reefs and the intercepting rods, thus preventing blockages. This facilitates the cleaning of the artificial reef, ensuring its passage capacity and allowing fish of suitable sizes to smoothly enter and exit their corresponding reef chambers, protecting the safe growth of fish fry and juveniles of different sizes within their respective chambers.

[0027] 2. This artificial reef, by setting up an inner reef channel dredging component, an outer reef channel dredging component, and a rotary drive component, cleans the inner reef channel by rubbing against the rods fixed on the outer reef when the inner reef is pulled upward. As the inner reef moves, it pushes the push plate, which then passes through the outer reef channel, scraping away impurities adhering to the inner wall of the channel. Furthermore, the lifting pressure seat rotates the shaft as it moves up and down, causing the intercepting blades on adjacent intercepting rods to move in an alternating manner, preventing the gaps between the intercepting blades from being completely blocked by impurities.

[0028] 3. This artificial reef, by setting up inserts and barriers between the intercepting rod and the outer reef, prevents larger fish from entering the space between the intercepting rod and the outer reef from above, thus avoiding large fish from entering the artificial reef to prey on juvenile fish and fry. By setting different widths of the passageways into the three-layered reef chambers, large juvenile fish cannot enter the fish chambers where small juvenile fish live, thus avoiding competition for food between large and small juvenile fish.

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] Example 1

[0049] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 The present invention provides an artificial reef, including a base 1, on which an inner reef body 2, an outer reef body 3, an intercepting rod 4 and a channel clearing mechanism are provided. The inner reef body 2 is movably disposed inside the outer reef body 3, the outer reef body 3 is fixedly installed on the upper surface of the base 1, the intercepting rod 4 is rotatably installed on the upper surface of the base 1 and is disposed on the outer side of the outer reef body 3, the inner reef body 2 has an inner reef access channel 21 on its side wall, and the outer reef body 3 has an outer reef access channel 31 on its side wall.

[0050] The interceptor bar 4 includes a rotating shaft 41 and an interceptor blade 42. The lower end of the rotating shaft 41 is rotatably mounted on the base 1, and the interceptor blades 42 on adjacent interceptor bars 4 are staggered.

[0051] The upper end of the inner reef 2 is connected to a rope 5, and the other end of the rope 5 is equipped with a buoy 6;

[0052] The channel clearing mechanism includes an inner reef channel clearing component 7, an outer reef channel clearing component 8, and a rotary drive component 9. The inner reef channel clearing component 7 includes an insert rod 71, which is fixedly installed on the outer reef body 3. One end of the insert rod 71 is slidably inserted into the inner reef inlet / outlet channel 21. When the inner reef body 2 moves up and down, the inner wall of the inner reef inlet / outlet channel 21 slides and rubs against the insert rod 71. The outer reef channel clearing component 8 includes a push plate 81, which is slidably installed inside the outer reef body 3. When the inner reef body 2 moves up and down, it pushes the push plate 81 to slide and rub against the inner wall of the outer reef inlet / outlet channel 31. The rotary drive component 9 includes a lifting pressure seat 91, which is slidably installed on the base 1. When the lifting pressure seat 91 moves up and down, it drives the rotating shaft 41 to rotate. The inner reef body 2 is placed on the upper surface of the lifting pressure seat 91.

[0053] As can be seen from the above, this artificial reef, through the combination of an outer reef body 3, an inner reef body 2, and an intercepting rod 4, forms a three-layer reef chamber for the growth of fish fry and juveniles of different sizes. The inner reef body 2 can move up and down inside the outer reef body 3. When the inner reef body 2 is pulled upwards, the inner reef access channel 21 on the inner reef body 2 rubs against the insert rod 71 fixed to the outer reef body 3, thereby cleaning the inner reef access channel 21. When the inner reef body 2 moves, it pushes the pusher plate 81, causing the pusher plate 81 to pass through the outer reef access channel 31, thus scraping away impurities adhering to the inner wall of the outer reef access channel 31. In addition, when the lifting pressure seat 91 moves up and down, it can drive the rotating shaft 41 to rotate, so that the intercepting blades 42 on the adjacent intercepting rods 4 move in an alternating manner. This can prevent the gaps between the intercepting blades 42 from being completely blocked by impurities, and prevent seaweed, shellfish and other organisms from breeding and growing between the outer reef access channel 31, the inner reef access channel 21 and the intercepting blades 42, thereby blocking the channels. This facilitates the cleaning of the artificial reef, ensures the passage performance of the artificial reef, and allows fish of suitable size to enter and exit the corresponding reef chamber smoothly, protecting the safe growth of fish fry and juveniles of different sizes in the corresponding reef chamber.

[0054] When using this artificial reef, the artificial reef is transported to the deployment location by ship. One end of rope 5 is connected to the top of the inner reef 2. Then, the hook of the crane is used to attach to rope 5 and lift the artificial reef. The crane cable is controlled to descend, and the artificial reef is slowly lowered into the water so that the lower surface of the base 1 contacts the bottom silt after the artificial reef sinks into the water. After the artificial reef is placed, the excess rope 5 is cut, leaving only the length of rope 5 that can extend to the water surface, and the buoy 6 is installed at the other end of rope 5.

[0055] Example 2

[0056] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the difference between this embodiment and the above embodiment is that the outer surface of the outer reef 3 is set as a frustum shape, the inclination angle of the outer side wall of the inner reef 2 is the same as the inclination angle of the inner wall of the outer reef 3, and the outer reef channel clearing component 8 also includes a sliding rod 82, a connecting plate 84, a mounting plate 85 and a return spring 86. The outer reef 3 is provided with sliding holes 32, which are respectively set on both sides of the outer reef inlet and outlet channel 31. The sliding rod 82 is slidably inserted into the inside of the sliding hole 32. The two ends of the connecting plate 84 are respectively fixedly connected to the sliding rod 82. The push plate 81 is fixedly installed on one end of the connecting plate 84 facing the outer reef inlet and outlet channel 31, and the mounting plate 85 is fixedly installed on the other end of the connecting plate 84. One end of the return spring 86 is fixedly connected to the mounting plate 85, and the other end of the return spring 86 is fixedly connected to the inner side wall of the outer reef 3.

[0057] As can be seen from the above, when the frustum-shaped structure is impacted by horizontal water flow, it can cause the water flow to rise, forming an upwelling flow, thereby allowing nutrients in the water to enter the interior of the outer reef body 3 through the outer reef inlet / outlet channel 31. Since the push plate 81 and the slide rod 82 are fixedly connected by the connecting plate 84, the push plate 81 can only slide horizontally. Since the inclination angle of the outer wall of the inner reef body 2 is the same as the inclination angle of the inner wall of the outer reef body 3, when the inner reef body 2 moves upward, it pushes the slide rod 82 to move horizontally, causing the push plate 81 to approach and enter the outer reef inlet / outlet channel 31, thereby scraping away the impurities adhering to the inner wall of the outer reef inlet / outlet channel 31. Due to the setting of the return spring 86, when the inner reef body 2 moves downward, the outer wall of the inner reef body 2 moves away from the slide rod 82, and the return spring 86 can pull the slide rod 82 to slide in the opposite direction, so that the push plate 81 moves away from the outer reef inlet / outlet channel 31, preventing the push plate 81 from blocking the outer reef inlet / outlet channel 31.

[0058] A roller 83 is rotatably mounted on the end of the slide rod 82 away from the slide hole 32. The roller 83 abuts against the outer wall of the inner reef 2, and the end of the slide rod 82 away from the roller 83 is always in contact with the inner wall of the slide hole 32.

[0059] As can be seen from the above, by setting the roller 83, the pushing effect on the slide bar 82 is better when the inner reef 2 moves upward, avoiding excessive friction between the inner reef 2 and the slide bar 82, which could cause the slide bar 82 to break. By setting the end of the slide bar 82 away from the roller 83 to always be in contact with the inner wall of the sliding hole 32, the situation that the slide bar 82 cannot accurately enter the sliding hole 32 when sliding after it comes out of the sliding hole 32 can be avoided.

[0060] Example 3

[0061] like Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, the difference between this embodiment and the above embodiment is that the rotating shafts 41 are arranged in a circular array on the outside of the base 1, the distance between adjacent rotating shafts 41 is not less than half the length of the intercepting blade 42, the rotation directions of adjacent rotating shafts 41 are opposite, a protrusion 11 is provided at the middle position of the upper surface of the base 1, a through-hole 12 is opened at the middle position of the protrusion 11, the lifting pressure seat 91 is slidably installed inside the through-hole 12, and an inlet and outlet hole 22 is opened at the bottom of the inner reef 2, which is located on the outside of the protrusion 11.

[0062] As can be seen from the above, since the distance between adjacent rotating shafts 41 is not less than half the length of the intercepting blade 42, the intercepting blade 42 will not collide with the adjacent rotating shaft 41 when rotating with the rotating shaft 41. By setting the opening 12, it is convenient for the lifting pressure seat 91 to slide up and down. By setting the inlet and outlet hole 22, fish can enter and exit from the bottom of the inner reef 2.

[0063] The rotary drive assembly 9 also includes a slide plate 92, a lifting plate 93, a fixed shaft 94, a rotating plate 95, and a support spring 97. A guide plate 13 is fixedly installed inside the base 1. The slide plates 92 are arranged in a circumferential array inside the base 1 and are slidably connected to the guide plate 13. One end of the lifting plate 93 is rotatably connected to the lower surface of the lifting pressure seat 91, and the other end of the lifting plate 93 is rotatably connected to one end of the slide plate 92. The fixed shaft 94 is fixedly installed at the other end of the slide plate 92. One end of the rotating plate 95 is fixedly connected to the rotating shaft 41, and the other end of the rotating plate 95 is provided with a sliding hole 96. The fixed shaft 94 is slidably connected to two adjacent sliding holes 96. The number of rotating shafts 41 is twice the number of slide plates 92. The two ends of the support spring 97 are fixedly connected to the inner bottom wall of the base 1 and the lower surface of the lifting pressure seat 91, respectively.

[0064] As can be seen from the above, under the support of the support spring 97, when the inner reef 2 is not pressed on the lifting pressure seat 91, the support spring 97 can push the lifting pressure seat 91 to move upward, so that one end of the lifting rotating plate 93 rises, thereby pulling the slide plate 92 to slide. Since the rotating plate 95 is provided with a sliding hole 96, when the rotating plate 95 can only rotate, the fixed shaft 94, which is slidably installed inside the sliding hole 96, can move and pull the rotating plate 95 to rotate, thereby making the rotating shaft 41 rotate.

[0065] Example 4

[0066] like Figure 2 , Figure 3 and Figure 4 As shown, the difference between this embodiment and the above embodiment is that a flow interceptor 33 is also fixedly installed on the outer wall of the outer reef 3, and the flow interceptor 33 is set above the outer reef access channel 31.

[0067] As can be seen from the above, by setting up the interceptor plate 33, more of the upwelling flow along the outer wall of the outer reef 3 can enter the outer reef access channel 31.

[0068] One end of the insertion rod 71 extends to the outside of the outer reef 3. A stop bar 34 is also fixedly installed on the outer wall of the outer reef 3. A support rod 35 is fixedly installed on the upper surface of the base 1. The upper end of the support rod 35 is fixedly connected to the bottom wall of the outer reef 3. Both the upper and lower ends of the outer reef 3 are provided with outlets 36.

[0069] As can be seen from the above, the end of the barrier rod 34 and the insertion rod 71 extending to the outside of the outer reef 3 cooperate to form a reef chamber between the outer reef 3 and the intercepting rod 4, which is composed of multiple straight rods to restrict the passage of fish with excessive size. By setting the support rod 35 and the outlet 36, juvenile fish can also enter the reef chamber between the outer reef 3 and the inner reef 2 from the upper and lower ends of the outer reef 3.

[0070] The spacing between adjacent insert rods 71 ​​is equal to the spacing between intercepting blades 42, the spacing between adjacent baffles 34 is equal to the spacing between intercepting blades 42, and the spacing between intercepting blades 42 is greater than the diameter of the outer reef access channel 31.

[0071] As can be seen from the above, by setting the spacing between adjacent insert rods 71 ​​and the spacing between adjacent baffles 34 to be equal to the spacing between intercepting blades 42, larger fish are prevented from entering the inner side of the intercepting rod 4 from above. Since the spacing between the intercepting blades 42 is greater than the diameter of the outer reef access channel 31, juvenile fish that can enter the reef chamber formed between the intercepting rod 4 and the outer reef 3 may not be able to enter the interior of the outer reef 3, thus ensuring that there is less food competition between smaller and larger juvenile fish.

[0072] The length of the support rod 35 and the spacing between adjacent support rods 35 are not greater than the diameter of the outer reef access channel 31. The difference between the outer diameter and the inner diameter of the outlet 36 is not greater than the diameter of the outer reef access channel 31. The diameter of the outer reef access channel 31 is greater than the width of the inner reef access channel 21.

[0073] As can be seen from the above, since the length of the support rod 35 and the distance between adjacent support rods 35 are not greater than the diameter of the outer reef access channel 31, and the difference between the outer diameter and the inner diameter of the outlet 36 is not greater than the diameter of the outer reef access channel 31, juvenile fish that cannot enter the interior of the outer reef body 3 through the outer reef access channel 31 also cannot enter the interior of the outer reef body 3 through the outlet 36. Since the diameter of the outer reef access channel 31 is greater than the width of the inner reef access channel 21, juvenile fish that can enter the interior of the outer reef body 3 may not be able to enter the interior of the inner reef body 2, thus ensuring that there is less food competition between smaller juvenile fish or fry and larger juvenile fish.

[0074] Example 5

[0075] Please see Figure 1 - Figure 8 The present invention also discloses a method for deploying a combined artificial reef, the specific steps of which are as follows:

[0076] The artificial reef is transported to the deployment location by ship, one end of rope 5 is connected to the top of the inner reef 2, and then the hook of the crane is used to attach to rope 5 and lift the artificial reef.

[0077] The crane cable is lowered to slowly lower the artificial reef into the water, so that the lower surface of the base 1 contacts the bottom silt after the artificial reef sinks into the water.

[0078] After the artificial reef is placed, cut off the excess rope 5, leaving only the length of rope 5 that can extend to the water surface, and install the buoy 6 at the other end of rope 5.

[0079] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

One end of the rotating plate is fixedly connected to the rotating shaft, and the other end of the rotating plate has a sliding hole. The fixed shaft is slidably connected to two adjacent sliding holes. The number of rotating shafts is twice the number of sliding plates. The two ends of the support spring are fixedly connected to the inner bottom wall of the base and the lower surface of the lifting pressure seat, respectively.

5. An artificial reef according to claim 1, characterized in that: A flow-blocking plate is also fixedly installed on the outer wall of the outer reef, and the flow-blocking plate is positioned above the entrance and exit channel of the outer reef.

6. An artificial reef according to claim 1, characterized in that: One end of the insertion rod extends to the outside of the outer reef. A stop bar is also fixedly installed on the outer wall of the outer reef. A support rod is fixedly installed on the upper surface of the base. The upper end of the support rod is fixedly connected to the bottom wall of the outer reef. Both the upper and lower ends of the outer reef have outlets.

7. An artificial reef according to claim 6, characterized in that: The spacing between adjacent inserts is equal to the spacing between intercepting blades, the spacing between adjacent baffles is equal to the spacing between intercepting blades, and the spacing between the intercepting blades is greater than the diameter of the outer reef access channel.

8. An artificial reef according to claim 6, characterized in that: The length of the support rod and the spacing between adjacent support rods are not greater than the diameter of the outer reef access channel. The difference between the outer diameter and the inner diameter of the outlet is not greater than the diameter of the outer reef access channel. The diameter of the outer reef access channel is greater than the width of the inner reef access channel.

9. A method for deploying a combined artificial reef, using an artificial reef as described in any one of claims 1-8, characterized in that, The specific steps are as follows: The artificial reef is transported to the deployment location by ship, one end of the rope is connected to the top of the inner reef, and then the hook of the crane is used to attach to the rope and lift the artificial reef. The crane cable is lowered to slowly lower the artificial reef into the water, so that the lower surface of the base of the artificial reef contacts the bottom silt after it sinks into the water. After the artificial reef is placed, cut off the excess rope, leaving only the length of the rope that can extend to the water surface, and attach the buoy to the other end of the rope.
