[0039] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0040] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0041] Example 1: A fixed growth tray for river floating plants, comprising:

[0042] The float 10 has a ring around its circumference and two sets of nets 11 are installed inside, with a seed-holding water-soluble cloth 12 sandwiched between the two sets of nets 11.

[0043] Anchor body 30 is connected to mesh 11 by plastic chain;

[0044] An ecological fish nest 20 is installed below the net 11. The ecological fish nest 20 includes a plant spawning bed 21 and a protective body 22. A vertical rod 23 is provided in the middle of the inner side of the protective body 22. An outwardly extending nozzle 24 is provided on the side of the protective body 22. Multiple flexible petals are provided circumferentially on the inner diameter of the nozzle 24. The flexible petals extend outward and are inclined towards the axis of the nozzle 24. The vertical rod 23 is connected to the net 11. The plant spawning bed 21 is slidably set on the vertical rod 23. The plant spawning bed 21 floats in the water, opens the top of the protective body 22, and exposes its body above the protective body 22.

[0045] In this scheme, the seed-clamping water-soluble cloth 12 is used to facilitate seed germination and growth when exposed to water. Secondly, the plant spawning bed 21 in the ecological fish nest 20 is in a suspended state under normal circumstances, that is, the buoyancy is slightly greater than its own weight. The surface of the spawning bed is provided with a concealment part that imitates the shape and color of aquatic plants. Under normal circumstances, it is exposed on the outside of the protective body 22, which helps to attract fish to approach and promote spawning. After the eggs are spawned, the plant spawning bed 21 will slowly fall due to its own weight overcoming the buoyancy until it enters the protective body 22, aligning the fish eggs and protecting them from fish swimming through and falling off. In addition, it can also prevent predatory fish such as snakehead, mandarin fish, and mandarin fish from swallowing them. After hatching, the fry can swim out of the protective body 22 through the external mouth 24. The flexible petals restrict the fish from entering the interior of the protective body 22 from the outside, which can scientifically and effectively promote the restoration of ecological diversity.

[0046] In Example 2, within the growth tray: the plant oviposition bed 21 is provided with vertically arranged peristaltic water supply nozzles 211. The top of the peristaltic water supply nozzles 211 is provided with a one-way inlet 2116, and the bottom is connected to several branch pipes 2111. Several sets of capillary pores are provided on the branch pipes 2111 for supplying water to the surface of the plant oviposition bed 21. A downwardly arranged pressurized branch 2112 is installed inside the peristaltic water supply nozzles 211. A piston body 2113 and a nickel-titanium alloy 2114 for the piston body 2113 to move along the inner wall of the pressurized branch 2112 are installed inside the pressurized branch 2112. A heat-conducting wire 2115 exposed on the outside of the plant oviposition bed 21 is embedded at the end of the pressurized branch 2112, and the end of the heat-conducting wire 2115 is exposed, while the body is covered with an insulation layer.

[0047] Heat is transferred from the end of the heat-conducting wire 2115 to the nickel-titanium alloy 2114. The nickel-titanium alloy 2114 deforms under heat, causing the piston body 2113 to move inside the pressurized branch 2112. This promotes water supply to the spawning bed area through the capillaries, forming a water flow, increasing local dissolved oxygen and reducing local high temperature, effectively ensuring normal hatching of fish eggs and preventing problems such as local high temperature and low oxygen.

[0048] In Example 3, within the growth tray: a guide diaphragm or multiple horn-shaped tubes with progressively decreasing dimensions along the water inlet direction are installed at the unidirectional water inlet 2116. Two sets of horn-shaped tubes are arranged in a staggered configuration, with the outlet of one set of tubes offset to one side of the axis and the outlet of the other set offset to the other side of the axis. This unidirectional water supply prevents the aggregation of fish egg waste and microorganisms, ensuring normal hatching of the fish eggs.

[0049] In Example 4, within the growth tray: a support 111 is mounted on the upper mesh 11. A photovoltaic power generation module 113 and a micro water pump 112 are mounted on the support 111. The inlet of the micro water pump 112 is connected to the river water inside the float 10 via a pipe. The outlet is connected to a rotating pipe 114 via a pipe passing through both sets of meshes 11. The rotating pipe 114 is vertically fitted onto the outside of the connection node between the chain and the mesh 11 and connected to a horizontal branch pipe 115. The horizontal branch pipe 115 has upward-sloping spray holes along its length, used to propel water flow and promote water movement within the float 10. It should be noted that the photovoltaic power generation module 113 is a conventional, mature product; the inventors only used it as the power source without any structural modifications. Water is pumped by the micro water pump 112 to supply water to the horizontal branch pipe 114, causing water to spray from the spray holes. The reaction force then acts as the rotational power, achieving rotational motion. Then, the bottom area of ​​the mesh 11 is cleaned to form water flow between the upper and lower layers, which helps to reduce the local temperature, prevents the mesh from becoming clogged, and avoids the water separation between the upper and lower layers of the mesh 11. Especially in the hot summer, this can prevent plants from being scalded.

[0050] The protective body 22 is a bottomed cylindrical structure made of plastic-coated mesh, which has good permeability and is conducive to the hatching of fish eggs.

[0051] The float 10 includes an inner ring fixing part 12 and an outer ring inflatable floating part 102. The inner ring fixing part 12 is provided with a grooved ring, and a clamp is installed in the grooved ring to fix the net 11. The net 11 is fixed to the inner ring fixing part 12 by clamping the clamp and the grooved ring. The outer ring inflatable floating part 102 is inflated to achieve the floating state of the entire float 10.

[0052] Both sets of mesh panels 11 are plastic-coated mesh panels 11, with the upper mesh panel 11 having a larger mesh size than the lower mesh panel 11. The mesh size of the lower mesh panel 11 is slightly smaller than the seed particle size.

[0053] The methods for river ecological restoration are as follows:

[0054] S100, Growth Disc Assembly:

[0055] A mesh 11 is placed on the upper and lower sides of the seed-clamping water-soluble cloth 12. The mesh 11 is a plastic-coated mesh, and the mesh size of the upper mesh 11 is larger than that of the lower mesh 11, thus obtaining the assembly.

[0056] The assembly is placed in the inner ring fixing part 101 and fixed by clamps and grooved rings;

[0057] A bracket 111 is installed on the upper mesh 11. A photovoltaic power generation module 113 and a micro water pump 112 are installed on the bracket 111. A pipe is installed at the inlet and outlet. The pipe passes through the two sets of meshes 11 and is connected to a rotating pipe 114. The rotating pipe 114 and the pipe are connected by a rotating water pipe joint. The rotating pipe 114 is rotatably installed on the outside of the node of the chain and the lower mesh 11 and is connected to a horizontal branch pipe 115 at the bottom. The end of the horizontal branch pipe away from the rotating pipe 114 is blocked.

[0058] A plant oviposition bed 21 is mounted on the vertical rod 23. The plant oviposition bed 21 is slidably set relative to the protective body. The top of the vertical rod 23 is welded and fixed to the mesh 11 below. Multiple sets of protective bodies 22 are arranged around the periphery and distributed around the area covered by the horizontal branch pipe 115.

[0059] Inflate the outer inflatable floating part 102 to provide buoyancy for the growth plate in the water;

[0060] S200, growth tray placement:

[0061] After the river is filled with water, the growth plate is deployed according to the river environment. The growth plate is fixed by the anchor 30 and the chain. The plant oviposition bed 21 is floating in the water, with its body exposed from inside the protective body 22 and floating above the protective body 22.

[0062] S300, Ecological Reconstruction:

[0063] Seeds inside the seed-soluble cloth 12 germinate and grow into seedlings when they come into contact with water. The photovoltaic power generation module 113 generates electricity, which is then supplied to the micro water pump 112 via its own energy storage device. Water is supplied to the horizontal branch pipe 115 via the rotating pipe 114. The horizontal branch pipe 115 rotates as the water is sprayed, and it cleans the mesh of the mesh 11.

[0064] In this step, a light sensor can be installed on the top of the inner side of the inner ring fixed part 101. The light sensor is electrically connected to the energy storage device via the control system and the micro water pump 112 to control the opening and closing of the micro water pump 112. When the plant grows into a seedling and blocks the light, the micro water pump 112 is turned on. The energy storage device has a built-in charging protection module. This part is the photovoltaic power generation component 113.

[0065] After the female fish lays eggs on the plant spawning bed 21, the plant spawning bed 21 changes weight and slowly falls into the protective body 22; the hatched fry swim on the outside of the protective body 22 through flexible petals.

[0066] After the heat-conducting wire 2115 absorbs heat at its end and transfers it to the nickel-titanium alloy 2114, when the set temperature exceeds the set value, its length increases, causing the piston body 2113 to move outward inside the pressurized branch 2112, supplying water unidirectionally to the branch pipe 2111. The capillaries on the branch pipe 2111 form a slow water flow on the surface of the plant spawning bed 21, promoting the hatching of fish eggs.

[0067] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made to the technical solutions and inventive concepts of the present invention should all be covered within the scope of protection of the present invention.
