Description

Technical Field

[0001] The utility model relates to the technical field of fish resource conservation and proliferation, in particular to an artificial fish nest capable of purifying water quality. Background Art

[0002] Many river fish lay sticky, sinking eggs, requiring them to attach to a substrate such as sand, gravel, and aquatic plants. Human activities, including sand mining, shipping, water conservancy projects, and industrial and agricultural pollution, have damaged the bottoms of rivers and lakes, deteriorating water quality and aquatic vegetation. This has led to a decline in fish spawning and rearing habitats, resulting in a decline in fish stocks. Artificial fish nests are an important tool for restoring fish stocks.

[0003] Currently, artificial fish nests are mostly constructed using materials such as palm leaves, bamboo leaves, and reeds. These materials are soft and easily broken, and are prone to spoilage when submerged in water for long periods of time. This reduces the adhesion of fish eggs and affects regional water quality. Furthermore, the spawning substrates used in artificial fish nests are mostly vertical linear structures such as reeds and hemp ropes. The amount of fish eggs that can adhere to a single unit of substrate is limited, requiring a large amount of substrate to achieve the desired effect. Consequently, the floating structures with fixed substrates occupy a large area of water and pose a risk of disrupting flood control and shipping.

[0004] The above information disclosed in the background technology section is only for enhancing understanding of the background of the present invention and therefore may contain information that does not constitute the prior art known to ordinary technicians in this field. Utility Model Content

[0005] The utility model aims to provide an artificial fish nest which can purify water quality, is not easy to corrupt, can purify water quality and has high water area utilization rate.

[0006] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0007] An artificial fish nest capable of purifying water of the utility model comprises:

[0008] A floating platform comprising:

[0009] The floating platform frame is divided into multiple units and floats on the water.

[0010] at least one buoyant drum connected to the buoyant platform frame via a rope and floating on the water surface, wherein the buoyant drum is connected to a steel anchor via a rope,

[0012] a floating assembly disposed in the unit to provide buoyancy;

[0013] Fish nest assembly, comprising,

[0014] The fish nest base is provided in the unit and has a plurality of slots.

[0015] The fish nest plate has its end vertically fixed in the slot to be immersed in water. The fish nest plate is a rectangular plate with a porous rough structure, and fish eggs adhere to the surface pores of the porous rough structure.

[0016] In the artificial fish nest capable of purifying water, the floating platform frame is a single-layer rectangular frame structure, and a plurality of units for fixing the floating components and the fish nest components are arranged inside.

[0017] In the artificial fish nest capable of purifying water, the floating platform frame is a rectangular frame composed of a plurality of hollow square tubes.

[0018] In the artificial fish nest capable of purifying water, interfaces for connecting ropes are provided at the bottom and sides of the four outer corners of the floating platform frame.

[0019] In the artificial fish nest capable of purifying water, an interface for connecting with the floating component and the fish nest component is provided in the unit.

[0020] In the artificial fish nest capable of purifying water, the floating component is a hollow cubic structure.

[0021] In the artificial fish nest capable of purifying water, a plurality of slot arrays are distributed on the fish nest base.

The polyurethane WPU spawning matrix is less prone to rot than traditional materials such as reeds, and has a longer effective service life. The underwater structure of the artificial fish nest is a fish nest board arranged at intervals, which can block underwater undercurrents and reduce the flow rate of water near the artificial fish nest, thereby providing a higher quality habitat for fry. The water quality near the artificial fish nest can be purified, thereby improving the livability of the fish nest habitat. The fish nest board can be disassembled and installed as a single piece, which is convenient for maintenance and can extend the overall life of the artificial fish nest.

[0062] In one embodiment, an artificial fish nest capable of purifying water includes a floating platform 1, a floating assembly 2, and a fish nest assembly 3. The floating platform 1 includes a floating platform frame 11, a buoy 12, and a bollard 13. The floating platform frame 11 is a rectangular frame 8 meters long and 2 meters wide, formed from several hollow polyvinyl chloride (PVC) square tubes. The plastic square tubes have a square cross-section and a side length of 20 cm. Ports are provided at the bottom and sides of the four corners of the floating platform frame 11, allowing it to connect to the floating drum 12 and bollard 13 via ropes.

The mooring pile 15 is provided with an interface, which is connected to the two corner sides of the outside of the floating platform frame 11 near the shore by a rope. The rope should be retracted to an appropriate length to stabilize the floating state of the floating platform frame. The interior of the floating platform frame 11 is divided into 26 units by hollow plastic square tubes, arranged in 13×2. The cross-section of the plastic square tube is square with a side length of 20 cm. The space specifications of each unit inside the floating platform frame 11 are 70cm×40cm×20cm in length×width×height. Each unit is provided with an interface, which can be connected to the floating component 2 and the fish nest component 3. 13 units inside the floating platform frame 11 are connected to the floating component 2, and the other 13 units are connected to the fish nest component 3, which are arranged at intervals.

It has connectors around its perimeter for connection to the platform frame 11. Six slots are arranged in a sequence within the fish nest base 31, measuring 34 cm (L x W x H) by 7 cm (H x H) by 20 cm (D x W x H). These slots have a tightening function, ensuring a stable hold of the fish nest plate 32.

[0065] The fish nest panels 32 are rectangular panels formed by uniformly mixing polyurethane (WPU) and dehydrated activated sludge, then drying and forming them. The polyurethane (WPU) has a porous, rough structure, encapsulating activated sludge particles within its internal pores, allowing fish eggs to adhere to the surface pores. The panels 32 have dimensions of 34 cm (width x thickness x length) by 7 cm (length x length). The ends of the panels 32 are vertically fixed into slots in the fish nest base 31 and submerged underwater, forming the underwater structure of the artificial fish nest. One to six panels 32 can be inserted into the slots in the fish nest base 31 as needed.

[0066] When the present invention is used, before the earliest spawning period of fish, a quiet area with still water of suitable water quality or a still and slow water area with a flow rate of less than 0.2m / s is selected to install the above-mentioned artificial fish nest. The artificial fish nest is avoided as much as possible from interference by human activities. During the spawning period of fish, the structure of the artificial fish nest, the water quality conditions of the area, etc. are regularly monitored, and the failed fish nest boards 32 are replaced in time to ensure the effectiveness of the fish nest. When replacing the failed fish nest boards 32, the adhered fish eggs need to be transferred. After the spawning period of fish is over, the above-mentioned artificial fish nest is disassembled, and the floating platform 1, the floating component 2, and the fish nest base 31 can be reused in the next fish spawning period. The fish nest board 32 should not be reused and can be harmlessly treated or used for water purification work in similar environments.
