[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4This embodiment provides a technical solution: a water injection and pH adjustment system for fish fry farming, including a fish fry farming pond 1 and a water tank 2. The fish fry farming pond 1 provides space for fish fry farming, and the water tank 2 provides space for storing new water. A water injection pipe 3 is provided at the outlet of the water tank 2. The branch ends of the water injection pipe 3 are connected to adjacent fish fry farming ponds 1. During water injection, new water from the water tank 2 is injected into the fish fry farming pond 1 through the water injection pipe 3. Simultaneously, some old water is discharged through the drain pipe at the lower end of the fish fry farming pond 1 to prevent excessive water in the pond. A water pump station 4 is connected in series in the middle of the main stream of the water injection pipe 3 to provide power for the flow of liquid. The upper surface of the casing of the water pump station 4 is provided with... The pH adjusting tank 7 has its outlet connected to the second inlet of the water pump station 4, and the first inlet of the water pump station 4 is connected to the outlet of the water tank 2. A second valve is connected in series between the pH adjusting tank 7 and the water pump station 4, and a first valve is connected in series between the water tank 2 and the water pump station 4. When the pH meter 9 detects that the pH value of the pool water exceeds the safe range, the first valve of the water pump station 4 is closed, disconnecting the connection between the water tank 2 and the water pump station 4. The second valve of the water pump station 4 is opened, connecting the pH adjusting tank 7 to the water injection pipe 3. The chemical agent in the pH adjusting tank 7 is evenly injected into the fish fry breeding pond 1 through the diversion component to adjust the pH value of the pool water in the fish fry breeding pond 1. The diversion mechanism 6 is also included.

[0021] Diversion mechanism 6 includes diversion rings 61 and diversion holes 62. The diversion rings 61 are vertically slidably connected to the inside of the fish fry rearing pond 1. The inner arc surface of the diversion rings 61 is provided with diversion holes 62. The diversion rings 61 are all connected to the branch pipes of the water injection pipe 3. The diversion rings 61 float on the water surface of the fish fry rearing pond 1. New water enters the inside of the diversion rings 61 through the water injection pipe 3 and is finally discharged from the diversion holes 62, evenly injecting new water and chemicals into the pond water. The diversion mechanism 6 also includes float plates 63 and corrugated pipes 64. The float plates 63 are respectively set on the upper surface of the diversion rings 61. Corrugated pipes 64 are provided between the water inlet of the diversion rings 61 and the branch pipes of the water injection pipe 3. The float plates 63 can be made of polyethylene plates. During the water injection process, the buoyancy generated by the liquid on the float plates 63 The float 63 drives the diversion ring 61 to move up and down with the change of the liquid level in the fish fry rearing pond 1. The corrugated pipe 64 expands and contracts, so that the float 63 always floats on the water surface of the fish fry rearing pond 1. The diversion ring 61 is immersed in the water, so that the injected new water flows out along the water surface of the pond, which promotes the agitation of the upper water surface of the pond, making the mixing of new water and old water more thorough. At the same time, it reduces the amount of sediment washed up by the water flow during the water injection process, improving the water injection effect. The diversion mechanism 6 also includes a baffle 65 and an outlet hole 66. The baffle 65 is rotatably connected to the inside of the diversion ring 61. The inner arc surface of the baffle 65 fits against the inner arc wall of the diversion ring 61. The inner arc surface of the baffle 65 is provided with outlet holes 66, which are installed in conjunction with the diversion holes 62. The diversion mechanism 6 also includes a push plate 67 and a spring 68. Two push plates 67, each located within the same diversion ring 61, are positioned at the front end of the baffle 65. Springs 68 are provided on the inner surfaces of the two push plates 67 facing each other. Support plates 10 are provided at the front end of each diversion ring 61. The ends of the springs 68 are fixedly connected to adjacent support plates 10. When new water enters the diversion ring 61, the springs 68 elastically limit the flow, causing the outlet hole 66 to misalign with the diversion hole 62. The baffle 65 prevents the new water from draining out of the diversion hole 62. After the new water fills the diversion ring 61, the water pressure exerts a force on the push plates 67, overcoming the elastic force of the springs 68, causing the baffle 65 to slide within the diversion ring 61. When the outlet hole 66 coincides with the diversion hole 62, the new water is evenly injected into the fish fry rearing pond 1 from the diversion hole 62, allowing the new water to simultaneously flow from the diversion hole 62 into the pond. The water flows out through the flow hole 62, improving the uniformity of water injection. The diversion mechanism 6 also includes guide columns 69, which are respectively set in the middle of the support plate 10. The guide columns 69 pass through the guide holes in the inside of the spring 68 and the surface of the push plate 67. The guide columns 69 are arc-shaped columns, providing guidance and support for the extension and retraction of the spring 68 and the movement of the push plate 67. It also includes a PLC controller 5, which is located in front of the water pump station 4. The input terminal of the PLC controller 5 is electrically connected to an external power supply to control the start and stop of the whole device. The upper surface of the fish fry breeding pond 1 is provided with mounting plates 8. The lower surface of the mounting plates 8 located at the left end of the fish fry breeding pond 1 is provided with pH meters 9 to detect the pH value of the pond water. The output terminal of the pH meter 9 is electrically connected to the input terminal of the PLC controller 5.The input terminal of the water pump station 4 is electrically connected to the output terminal of the PLC controller 5. It also includes limit posts 11, which are respectively installed on the lower surface of the mounting plate 8 located at the left end of the fish fry rearing pond 1. The limit posts 11 are vertically slidably connected to the round holes on the surface of the float plate 63. Through the vertical sliding of the limit posts 11 and the float plate 63, the rotation of the float plate 63 is restricted during its up-and-down movement.

[0022] The working principle of the water injection and pH adjustment system for fish fry farming provided by this utility model is as follows: During the fish fry farming process, the water pump station 4 is started by the PLC controller 5, so that the new water in the water tank 2 enters the inside of the diversion ring 61 through the water injection pipe 3. At this time, under the elastic limit of the spring 68, the outlet hole 66 is misaligned with the diversion hole 62, and the baffle 65 prevents the new water from being discharged from the diversion hole 62. After the new water fills the inside of the diversion ring 61, the water pressure applies a force to the push plate 67, overcoming the elastic force of the spring 68, so that the baffle 65 slides inside the diversion ring 61. When the outlet hole 66 coincides with the diversion hole 62, the new water is evenly injected into the fish fry farming pond 1 from the diversion hole 62. During the water injection process, under the buoyancy of the liquid on the float plate 63, the float plate 63 drives the diversion ring 64 to move. The flow ring 61 moves up and down with the change of the liquid level in the fish fry rearing pond 1, and the corrugated pipe 64 expands and contracts, so that the float 63 always floats on the water surface of the fish fry rearing pond 1. The diversion ring 61 is immersed in the water, so that the injected new water flows out along the water surface of the pond, which promotes the agitation of the upper water surface of the pond, making the mixing of new water and old water more thorough. At the same time, it reduces the amount of sediment washed up by the water flow during the water injection process, and improves the water injection effect. Similarly, when the pH meter 9 detects that the pH value of the pond water exceeds the safe range, the first valve of the water pump station 4 is closed, the connection between the water tank 2 and the water pump station 4 is disconnected, and the second valve of the water pump station 4 is opened, so that the pH adjustment tank 7 is connected to the water injection pipe 3. The chemical agent in the pH adjustment tank 7 is evenly injected into the fish fry rearing pond 1 through the diversion component to adjust the pH value of the pond water in the fish fry rearing pond 1.

[0023] It is worth noting that the PLC controller 5 disclosed in the above embodiments can be an NX7 model PLC controller, while the water pump station 4 and pH meter 9 can be freely configured according to the actual application scenario. The water pump station 4 can be a 125D25 model water pump station, and the pH meter 9 can be a PHSJ-3F model pH meter. The PLC controller 5 controls the operation of the water pump station 4 and pH meter 9 using methods commonly used in the prior art.

[0024] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
