Description

Technical Field

[0001] This invention relates to the field of aquaculture technology for fish and other aquatic animals, specifically to an artificial reef that prevents blockage. Background Technology

[0002] Artificial reefs are man-made accumulations on the bottom of bodies of water designed to attract and inhabit fish. They provide shelter for fish and other aquatic animals, resulting in a significant fish-attracting effect and extending the time fish spend in the reef area, thus expanding fish farms. In freshwater lakes, reservoirs, and rivers, especially in areas with simple bottom topography, the relatively flat bottom makes it difficult for fish and other aquatic animals to avoid predators (especially vulnerable juveniles), making it difficult to attract fish to gather or inhabit these areas. Consequently, it is difficult for such waters to form a complete ecosystem, leading to low economic yields. To address this problem, those skilled in the art typically deploy artificial reefs in these waters to attract fish and create a more complete ecosystem. This facilitates the aquaculture of fish and other aquatic animals, effectively protects economically important aquatic animals, improves their survival rates, provides a good habitat and foraging grounds for fish and other aquatic animals, and contributes to a multiplied or even multiplied increase in resources.

[0003] However, in relatively flat waters, the lack of topographical obstruction allows sediment to easily be washed into the cavities of the artificial reefs intended to shelter fish. Over time, this blockage affects the reef's efficiency and can even render it unusable, thus negating its original purpose.

[0004] In summary, existing technologies for artificial reefs suffer from the problem of being easily blocked by silt. Summary of the Invention

[0005] The purpose of this invention is to provide an artificial reef that is prevented from being blocked, thereby solving the problem that existing artificial reefs are easily blocked by mud and sand.

[0006] The technical solution adopted by this invention to solve its technical problem is:

[0007] An artificial reef designed to prevent blockage includes a base, a fish-protecting body, and a connecting system. The fish-protecting body includes a fish-protecting frame, frame legs, a flow guide plate, a plate support assembly, a bottom sleeve, and several partitions. The fish-protecting frame is a cuboid frame structure. Each partition is disposed within the fish-protecting frame, and the upper part of each partition is rotatably connected to the upper part of the fish-protecting frame. The rotation axes of each partition are parallel to each other. The lower part of the fish-protecting frame is provided with several limiting protrusions, which are used to limit the range of rotation of the partitions. The flow guide plate is disposed below the fish-protecting frame, and the frame legs are connected between the flow guide plate and the fish-protecting frame. The upper surface of the flow guide plate is high in the middle and low around the edges.

[0008] The disk support assembly is connected to the lower side of the guide disk. The disk support assembly includes at least three disk supports. Each disk support has a ball groove on its lower end face, and a ball is provided in the ball groove. Each disk support and each ball is used to support the guide disk on the base. The upper end of the base is provided with a base shaft, which is vertically arranged. The bottom sleeve is provided on the lower side of the guide disk and is sleeved on the base shaft. The bottom sleeve can rotate on the base shaft. The connection system is used to prevent the bottom sleeve and the base shaft from separating.

[0009] Furthermore, each of the disc supports is distributed around the base axis, and each of the disc supports is evenly distributed around the base axis.

[0010] Furthermore, the connection system includes a plurality of tension springs, the upper end of each tension spring being connected to the guide plate, the lower end of each tension spring being connected to the base, and the tension springs being distributed around the bottom sleeve.

[0011] Furthermore, an upper bolt is connected to the bottom of the guide plate, and a lower bolt is connected to the upper end of the base. The upper bolt is used to connect the upper end of the tension spring, and the lower bolt is used to connect the lower end of the tension spring.

[0012] Furthermore, the connection system includes a pin device, a pin hole on the base shaft, and a through hole on the bottom sleeve. The through hole is located on the side of the bottom sleeve, and the pin hole is arranged radially along the base shaft. The pin device includes a pin shaft and two locking sleeves. The pin shaft is inserted into the pin hole and passes through the through hole. Each locking sleeve is distributed and sleeved on the pin shaft. The two locking sleeves are distributed on both sides of the base shaft. Each locking sleeve is provided with a sleeve nut. The pin shaft and the sleeve nut are threadedly connected. The outer diameter of the locking sleeve is larger than the diameter of the pin hole, and the locking sleeve can swing with the pin shaft in the through hole.

[0013] Furthermore, each of the locking sleeves is rotatably connected to a roller that passes through the perforation.

[0014] Furthermore, the fish protection frame is connected to two wing plates, each wing plate is vertically arranged, each wing plate is parallel to each other, and each wing plate is parallel to one of the horizontal diagonals of the fish protection frame.

[0015] Furthermore, each of the partitions has a rotating shaft on both sides of its upper part, and the two rotating shafts on the same partition are coaxially arranged. The upper end of the fish guard is provided with a rotating shaft groove with an opening at the top. The rotating shaft is placed in the rotating shaft groove and can rotate in the rotating shaft groove. The upper end of the fish guard is detachably connected with a cover plate, which is used to seal the opening at the top of the rotating shaft groove.

[0016] The beneficial effects of this invention are as follows: This invention provides an artificial reef that prevents clogging. During use, the base is used to lower the entire invention to the bottom of the aquaculture area. In the fish protection frame, the area between two adjacent partitions provides a shelter for the fish. Since this invention is used in aquaculture ponds or lakes, the water is fluid, and the direction and velocity of the flow change. The water flow causes the partitions to rotate on the fish protection frame. Under the action of the limiting protrusions, this rotation can also be described as a small-amplitude swaying. The swaying between the partitions causes changes in the volume between the partitions, thereby promoting water flow, which is beneficial for the discharge of sediment from the area between the partitions. At the same time, the frame structure of the fish protection frame not only provides a wide passage for fish to enter and exit the fish protection frame, but also facilitates water quality exchange between the area between the partitions and the surrounding water, which is also beneficial for the discharge of sediment. The silt brought by the water flow is partly carried away by the water flow, and partly settled under gravity. The settled silt falls onto the upper surface of the guide plate, and the structure of the upper surface of the guide plate, which is higher in the middle and lower around the edges, facilitates the discharge of silt. This invention, by setting up a plate support, bottom sleeve, rolling ball, and base shaft, allows the guide plate to rotate at a certain angle, and the rolling ball ensures smooth rotation. The power for the rotation of the guide plate comes from the scouring of the baffle by the water flow. The rotation of the guide plate facilitates the shedding of silt from the guide plate, thereby improving the sewage discharge capacity of this invention. Through the interaction of the above-mentioned silt discharge principles, the ability of this invention to prevent siltation is greatly improved, solving the problem of silt clogging in existing artificial reefs.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, 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.

[0031] like Figures 1 to 4As shown, the present invention includes a base 1, a fish protector body, and a connecting system. The fish protector body includes a fish protector frame 2, frame supports 21, a flow guide plate 3, a plate support assembly, a bottom sleeve 32, and several partitions 4. The fish protector frame 2 is a cuboid frame structure. Each partition 4 is disposed in the fish protector frame 2, and the upper part of each partition 4 is rotatably connected to the upper part of the fish protector frame 2. Each partition 4 has a rotating shaft 41 on both sides of its upper part, and two rotating shafts 41 located on the same partition 4 are coaxially arranged. The upper end of the fish protector frame 2 is provided with a rotating shaft groove 25, which is open at the top. The rotating shaft 41 is placed in the rotating shaft groove 25 and can rotate in the rotating shaft groove 25. The cooperation between the rotating shaft 41 and the rotating shaft groove 25 serves as a way for the partitions 4 to be rotatably connected in the fish protector frame 2. A cover plate 7 is detachably connected to the upper end of the fish protector frame 2. The cover plate 7 is used to seal the upper opening of the rotating shaft groove 25. The present invention, by providing a rotating shaft 41, a rotating shaft groove 25, and a cover plate 7, facilitates the installation and removal of the partition 4 on the fish protection frame 2, and facilitates the production, processing, assembly, and transportation of the present invention. The partition 4 is preferably made of a material with a density lower than water, such as PVC.

[0032] The rotation axes of each partition 4 are parallel to each other. The lower part of the fish protection frame 2 is provided with several limiting protrusions 22, which are used to limit the range of rotation of the partition 4. A gap 23 is formed between two adjacent limiting protrusions 22 on the same edge of the cuboid frame structure of the fish protection frame 2. The lower end of the corresponding partition 4 passes through this gap. Due to the limitation of the width of this gap 4, the swing range of the partition 4 is limited.

[0033] like Figures 5 to 7 As shown, the flow guide plate 3 is located below the fish guard frame 2, and the frame support 21 connects the flow guide plate 3 and the fish guard frame 2. The upper surface of the flow guide plate 3 is shaped with a high center and low edges, for example, the upper surface of the flow guide plate can be set into a spherical or conical shape. The plate support column group is connected to the lower side of the flow guide plate 3. The plate support column group 31 includes at least three plate support columns 31. Each plate support column 31 has a ball groove on its lower end face, and a ball 33 is provided in the ball groove. Each plate support column 31 and each ball 33 is used to support the flow guide plate 3 on the base 1.

[0034] like Figures 7 to 11 As shown, the upper end of the base 1 is provided with a base shaft 41, which is vertically arranged. The bottom sleeve 32 is provided on the lower side of the guide plate 3 and is sleeved on the base shaft 41. The bottom sleeve 32 can rotate on the base shaft 41. The connection system is used to prevent the bottom sleeve 32 and the base shaft 41 from separating.

[0035] like Figure 10 and Figure 11 As shown, each disc support 31 is distributed around the base rotation axis 41, and each disc support 31 is evenly distributed around the base rotation axis 41.

[0036] like Figures 1 to 6 As shown, in the manufacturing process of this invention, the base 1 is preferably made of concrete. The fish guard 2, support legs 21, wing plates 24, flow guide plate 3, and plate support column 3 are preferably made of lightweight materials with a density less than water, such as PVC. The fish guard 2, support legs 21, wing plates 24, flow guide plate 3, and plate support column 3 can be an integral structure.

[0037] like Figures 1 to 6 In use, the base 1 lowers the entire invention to the bottom of the aquaculture area. In the fish protection frame 2, the area between two adjacent partitions 4 provides shelter for the fish. Since the invention is used in aquaculture ponds or lakes, where the water is fluid and its direction and velocity change, the water flow causes the partitions 4 to rotate on the fish protection frame. This rotation, aided by the limiting protrusions 22, can be described as a small-amplitude swaying. This swaying between the partitions causes changes in their volume, promoting water flow and facilitating the removal of sediment from the area between the partitions 4. Simultaneously, the frame structure of the fish protection frame 2 not only provides a wide passage for fish to enter and exit the frame but also facilitates water exchange between the area between the partitions and the surrounding water, further promoting sediment removal. The silt brought by the water flow is partly carried away by the water flow, and partly settled under the influence of gravity. The settled silt falls onto the upper surface of the guide plate 3. The structure of the upper surface of the guide plate 3, which is higher in the middle and lower around the edges, facilitates the discharge of silt. This invention, by setting up the plate support 31, bottom sleeve 32, ball bearing 33, and base shaft 11, allows the guide plate 3 to rotate at a certain angle. The ball bearing 33 ensures smooth rotation. The rotation of the guide plate 3 is powered by the water flow scouring the baffle 4. Two wing plates 24 are connected to the fish protection frame 2. Each wing plate 24 is vertically arranged and parallel to each other, and each wing plate 24 is parallel to one of the horizontal diagonals of the fish protection frame 2. By setting up the wing plates, the force of the water flow on the rotation of the guide plate can be increased. The rotation of the guide plate 3 facilitates the removal of silt from the guide plate 3, thereby improving the sewage discharge capacity of this invention. Through the interaction of the above-mentioned principles of sediment removal, the ability of this invention to prevent sediment accumulation is greatly improved, and the problem of artificial reefs being easily blocked by sediment in the prior art is solved.

[0038] like Figures 6 to 11As shown, in the first embodiment of the connection system, the connection system includes several tension springs 5. The upper end of each tension spring 5 is connected to the guide plate 3, and the lower end of each tension spring 5 is connected to the base 1. The tension springs 5 ​​are distributed around the bottom sleeve 32. In actual use, elastic ropes can be used instead of tension springs. Each tension spring provides tension between the guide plate 3 and the base 5. The tension provided by each tension spring 5 is used to maintain the base shaft 41 in the bottom sleeve 32, preventing the bottom sleeve from falling off the base shaft. In addition, when the guide plate 3 rotates relative to the base 1, when the water flow speed is unstable, the guide plate 3 can rebound after rotation. This rebound action is very beneficial for throwing out mud and sand on the upper surface of the guide plate 3, improving the effect of sewage and debris discharge, and preventing mud and sand from accumulating under the fish guard. The bottom of the guide plate 3 is connected to an upper bolt 34, and the upper end of the base 1 is connected to a lower bolt 12. The upper bolt 34 is used to connect the upper end of the tension spring 5, and the lower bolt 12 is used to connect the lower end of the tension spring.

[0039] like Figures 6 to 12 As shown, in a second embodiment of the connection system, the connection system includes a pin device, a pin hole 13 on the base shaft 41, and a through hole 35 on the bottom sleeve 32. The through hole 35 is located on the side of the bottom sleeve 32, and the pin hole 13 is arranged radially along the base shaft 41. The pin device includes a pin 6 and two locking sleeves 61. The pin 6 is inserted into the pin hole 13 and passes through the through hole 35. Each locking sleeve 61 is distributed and sleeved on the pin 6. The two locking sleeves 61 are distributed on both sides of the base shaft 41, and each locking sleeve 61 is provided with a sleeve nut 62. The pin 6 and the sleeve nut 62 are threadedly connected. The outer diameter of the locking sleeve 61 is larger than the diameter of the pin hole 13, and the locking sleeve 61 can swing with the pin 6 in the through hole 35. Each locking sleeve 61 is used to prevent the pin 61 from falling out of the pin hole 13 and the through hole 35. The perforation 35, in conjunction with the pin device, serves two purposes: firstly, to prevent the bottom sleeve 32 from detaching from the base shaft; and secondly, to limit the range of rotation of the bottom sleeve 32 on the base shaft 41. During use, a locking nut 63 can be threaded onto the pin 6 to prevent the sleeve nut from rotating. Each locking sleeve 61 is rotatably connected to a roller 64, which passes through the perforation 35. The roller 64 improves the smoothness of the relative movement of the pin device within the perforation 35, thus ensuring smooth rotation of the guide plate. The roller 64 can be connected via a bearing 65. This connection method enhances the reliability of the connection between the guide plate and the base, reducing the risk of disintegration at the bottom of the aquaculture area.

[0040] In practical use, either of the two implementation schemes of the above connection system can be used, or both can be used simultaneously.
