AI Technical Summary
Existing breeding reefs are ineffective at attracting parent fish populations and preventing fish from escaping from marine ranches, resulting in low efficiency in fisheries resource conservation.
Wave generators and bubble generators are added to the breeding reefs. The bubble generators produce bubbles to form a visual barrier. The oscillating motion of the wave generator drives the bubble generator to produce bubbles, forming a dynamic bubble curtain to interfere with fish swimming and improve the interception and escape rate.
The visual interference effect of the bubble barrier enhances the retention rate of fish in marine ranches, thereby improving the efficiency of fishery resource protection and yield.

Abstract
Description
Technical Field
[0001] This utility model relates to the fields of marine biological resource survey, seaweed farms, and fishery resource protection, specifically an underwater breeding reef for controlling the swimming direction of fish. Background Technology
[0002] In the field of artificial reefs, to increase fishery production and improve the efficiency of fishery resource enhancement in local sea areas, it is necessary to construct marine ranches and use artificial reefs to protect each stage of the fishery resource's life cycle, thereby increasing the survival rate and reducing the mortality rate of fishery resources in the wild, and ultimately increasing fishery production in the region. To achieve the goal of covering the entire life cycle, it is necessary to attract and retain juvenile fish within a certain space to improve their reproductive efficiency. The design of artificial reefs serves two purposes: attraction and spawning. However, existing artificial reefs cannot effectively attract parent fish groups, and fish schools easily escape from marine ranches, failing to effectively form small-scale aquaculture areas. Utility Model Content
[0003] In view of the problems existing in the prior art, this utility model provides an underwater breeding reef for controlling the swimming direction of fish, so as to solve at least one of the above-mentioned technical problems.
[0004] The technical solution of this utility model is: an underwater breeding reef for controlling the swimming direction of fish, comprising a breeding reef body, characterized in that a wave power generation device is provided above the breeding reef body, the wave power generation device floats on the sea surface, anchor chains are provided on both sides of the wave power generation device, one end of the anchor chain is fixed to the bottom of the wave power generation device, and the other end of the anchor chain is inserted into the seabed through an anchor hook, a bubble generator is installed below the swing plate of the wave power generation device, the swing plate of the wave power generation device is directly connected to the water pump plunger of the bubble generator through a rigid connecting rod, and an exhaust pipe is provided below the bubble generator;
[0005] The main body of the aquaculture reef includes a first layer of reef, a second layer of reef, and a third layer of reef stacked from top to bottom. The first layer of reef is a cubic reef with a hollow interior and each face of the first layer of reef has a circular through hole communicating with the interior. The second layer of reef and the third layer of reef are both hexagonal reefs with a hollow interior and each face of the hexagonal reef has a through hole communicating with the interior.
[0006] The exhaust pipe is located inside the third reef, and the main body of the aquaculture reef is located between two anchor chains.
[0007] This invention adds a bubble generator to the aquaculture reef, enabling the generation of bubbles from the inside out. These bubbles rise vertically in the water, forming a curtain. Fish perceive this dynamic bubble swarm as a physical barrier, actively adjusting their swimming direction or stopping altogether. This visual disturbance effect improves the interception rate of fish in marine ranches. The reciprocating motion of the wave generator's oscillating plate compresses or stretches the plunger, pressurizing the water flow and feeding it into the bubble generator to produce bubbles. The hollow interior of the aquaculture reef facilitates bubble generation.
[0008] Further preferably, the central axes of the first reef layer, the second reef layer, and the third reef layer coincide with each other.
[0009] It allows for easy insertion of the bubble generator into the aquaculture reef, facilitating the rise of bubbles from the bottom up.
[0010] Further preferably, the maximum length of the second reef layer is greater than the maximum length of the first reef layer, and the maximum length of the third reef layer is greater than the maximum length of the second reef layer.
[0011] Arranging the items from top to bottom increases stability.
[0012] Further preferably, the surface of the exhaust pipe is uniformly distributed with small holes.
[0013] It facilitates the generation of a large number of bubbles.
[0014] Preferably, the length of the exhaust pipe is greater than the length of the second reef layer, and the length of the exhaust pipe is less than the length of the third reef layer.
[0015] This allows for better containment of the bubbles around the breeding reef.
[0016] In a further preferred embodiment, a pressure pipe is connected between the exhaust pipe and the bubble generator, and the pressure pipe passes through a circular through-hole located at the top of the first layer of reef.
[0017] The effect of bubble generation has been optimized. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings.
[0021] Reference Figure 1As shown, an underwater aquaculture reef for controlling fish swimming direction includes an aquaculture reef body. A wave power generation device 1 is installed above the aquaculture reef body and floats on the sea surface. Anchor chains 2 are installed on both sides of the wave power generation device. One end of the anchor chain is fixed to the bottom of the wave power generation device, and the other end of the anchor chain is inserted into the seabed through an anchor hook. A bubble generator is installed below the swing path of the wave power generation device. The swing plate of the wave power generation device is directly connected to the water pump plunger of the bubble generator through a rigid connecting rod. An exhaust pipe 6 is installed below the bubble generator. The aquaculture reef body includes a first layer reef 3, a second layer reef 4, and a third layer reef 5 stacked from top to bottom. The first layer reef is a cubic reef with a hollow interior and each face of the first layer reef has a circular through hole communicating with the interior. The second and third layers reefs are hexagonal reefs with a hollow interior and each face of the hexagonal reef has a through hole communicating with the interior. The exhaust pipe is located inside the third layer reef, and the aquaculture reef body is located between two anchor chains.
[0022] This invention adds a bubble generator to the aquaculture reef, enabling the generation of bubbles from the inside out. These bubbles rise vertically in the water, forming a curtain. Fish perceive this dynamic bubble swarm as a physical barrier, actively adjusting their swimming direction or stopping altogether. This visual disturbance effect improves the interception rate of fish in marine ranches. The reciprocating motion of the wave generator's oscillating plate compresses or stretches the plunger, pressurizing the water flow and feeding it into the bubble generator to produce bubbles. The hollow interior of the aquaculture reef facilitates bubble generation.
[0023] Further optimization involves ensuring that the central axes of the first, second, and third reef layers coincide. This facilitates the insertion of a bubble generator into the reef, allowing bubbles to rise from the bottom up.
[0024] Further optimization resulted in the second reef layer having a maximum length greater than the first reef layer, and the third reef layer having a maximum length greater than the second reef layer. This top-to-bottom arrangement increased stability.
[0025] Further optimization involves evenly distributed small holes on the surface of the exhaust pipe, facilitating the generation of a large number of bubbles.
[0026] Further optimization involves venting the air duct to a length greater than the second reef layer and shorter than the third reef layer. This allows for better containment of the air bubbles around the breeding reef.
[0027] Further optimization involves connecting the exhaust pipe and the bubble generator with a pressure pipe 7, which passes through a circular through-hole located at the top of the first reef layer. This improves the bubble generation effect.
[0028] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
