Description

Technical Field

[0001] This invention relates to the field of disinfection device technology, specifically a fishpond disinfection device for fish farming. Background Technology

[0002] In aquaculture, the water in fish ponds is disinfected regularly to ensure the fish grow healthier. However, when disinfecting fish ponds manually, disinfectant powder is simply thrown into the pond without proper mixing, resulting in poor disinfection and water quality.

[0003] A fishpond disinfection device for aquaculture, disclosed in authorization announcement number CN107873620B, provides a method that eliminates the need for manual addition of disinfectant powder to the fishpond. It involves drawing water from the pond, thoroughly mixing it with the disinfectant powder, and then discharging the water, resulting in excellent disinfection and improved water quality. The device includes a base plate, support rods, a housing, an inlet pipe, and an outlet pipe. Support rods are installed on both sides of the top of the base plate, and the housing is installed between the tops of the support rods. This invention, through its mixing device, can agitate the water and disinfectant powder in the fishpond, thereby improving water quality and promoting healthier fish growth. It achieves the goal of eliminating the need for manual addition of disinfectant powder to the pond, allowing for thorough mixing of the water and disinfectant powder before discharge, while maintaining excellent disinfection and improved water quality.

[0004] When the above-mentioned device is in use, the rate at which disinfectant powder is added is independent of the flow rate of the inlet and outlet pipes. When the inlet and outlet water flow rates increase, the residence time of the water in the system is shortened, resulting in a decrease in the concentration of the disinfectant powder and thus weakening the disinfection effect. Conversely, when the inlet and outlet water flow rates decrease, the residence time of the water is prolonged, and the concentration of disinfectant powder continues to accumulate. Although the disinfection intensity can be maintained, it will result in excessive disinfectant dosage, leading to unnecessary resource consumption and cost waste. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention proposes a fishpond disinfection device for fish farming.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fishpond disinfection device for fish farming, comprising a disinfection box, a first three-way pipe provided on one side of the disinfection box, both ends of the first three-way pipe penetrating the disinfection box and extending into the interior of the disinfection box, a switch control component connected to the end of the first three-way pipe located inside the disinfection box, a piston slidably connected to the inner wall of the disinfection box, and two conduits fixedly connected to the upper surface of the disinfection box, one end of each of the two conduits penetrating the disinfection box and extending into the interior of the disinfection box, an annular groove opened on the side wall of the conduit located inside the disinfection box, a stop rod rotatably connected to the inner wall of the annular groove, a material leakage groove opened on the outer wall of the stop rod, and a through hole opened at one end of the stop rod, a drive connector provided in the through hole, and one end of the drive connector fixedly connected to the piston, a second three-way pipe provided at the bottom of the disinfection box, both ends of the second three-way pipe communicating with the disinfection box, and a control valve fixedly connected to the inner wall of the second three-way pipe.

[0007] Preferably, the switch control assembly includes a housing communicating with the first three-way pipe, and a stop block is slidably connected to the inner wall of the housing. An annular hole is opened on one side wall of the stop block, and a limit plate is fixedly connected to one end of the stop block. A first magnet is fixedly connected to the other end of the stop block. A clearance hole and a through hole are opened on one side wall of the piston, and a second magnet is fixedly connected to the inner wall of the clearance hole. A connecting rod is slidably connected to the inner wall of the through hole, and both ends of the connecting rod are fixedly connected to the two limit plates respectively. A material leakage hole is opened at the bottom of the housing.

[0008] Preferably, the drive connector includes a long rod that is slidably connected to the inner wall of the through hole. The inner wall of the through hole is provided with a spiral guide groove, and a protrusion is provided in the spiral guide groove. One end of the protrusion is fixedly connected to the long rod, and one end of the long rod is fixedly connected to the piston.

[0009] Preferably, one end of the protrusion is rotatably connected to a rotating block, and the sidewall of the rotating block is slidably connected to the spiral guide groove.

[0010] Preferably, the end of the baffle rod away from the long rod passes through the annular groove and is rotatably connected to the inner wall of the disinfection box, and a stirring rod is fixedly connected to the outer wall of the baffle rod.

[0011] Preferably, limit bars are provided on both sides of the piston, and the limit bars are fixedly connected to the inner wall of the disinfection box.

[0012] Preferably, the outer wall of the piston is fixedly fitted with a rubber sleeve, and the outer wall of the rubber sleeve is interference-fitted with the inner wall of the disinfection box.

[0013] Preferably, the upper end of the conduit is connected to a hopper.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention, through the coordinated use of a piston and a switch control component, allows the switch control component to close or open one end of the first three-way pipe after the piston moves to a certain position, causing the piston to move in a different direction. Furthermore, by providing a drive connector, the piston's movement drives a stop lever to rotate. When the stop lever rotates, the material trough located above it rotates downwards, allowing disinfectant powder to fall into the disinfection tank, thus completing the addition of disinfectant powder. In this way, the piston's movement controls the addition of disinfectant powder, and this movement is related to the water flowing into the disinfection tank, ensuring a stable ratio of disinfectant powder to water. This prevents the disinfectant powder concentration from decreasing, thus reducing the disinfection effect, or from excessive disinfectant dosage, leading to unnecessary resource waste and cost overruns.

[0016] This invention utilizes a long rod and a spiral guide groove in conjunction. When the piston moves, it drives the long rod, which in turn moves a protrusion. The protrusion, through the spiral guide groove, drives a stop rod to rotate. As the stop rod rotates, the material discharge trough located above it descends, allowing disinfectant powder to fall into the disinfection tank, thus completing the addition of disinfectant powder. This eliminates the need for an external drive device to add the disinfectant powder; the movement of the piston is sufficient. This results in a simple structure, low manufacturing cost, and high practicality.

[0017] 3. In this invention, by setting a baffle rod that is rotatably connected to the inner wall of the disinfection box at one end, the stability of the baffle rod rotation can be increased. Furthermore, by setting a stirring rod on the outer wall of the baffle rod, the rotating baffle rod can drive the stirring rod to rotate when the baffle rod rotates. The rotating stirring rod can stir the disinfectant powder solution, ensuring that the disinfectant powder and water can be fully mixed. Attached Figure Description

[0027] 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.

[0028] Please see Figures 1-8 A fishpond disinfection device for fish farming includes a disinfection box 1. A first three-way pipe 2 is provided on one side of the disinfection box 1, and both ends of the first three-way pipe 2 penetrate the disinfection box 1 and extend into the interior of the disinfection box 1. A switch control component is connected to the end of the first three-way pipe 2 located inside the disinfection box 1. A piston 3 is slidably connected to the inner wall of the disinfection box 1, and two conduits 4 are fixedly connected to the upper surface of the disinfection box 1. One end of each of the two conduits 4 penetrates the disinfection box 1 and extends into the interior of the disinfection box 1. An annular groove 5 is opened on the side wall of the conduit 4 located inside the disinfection box 1, and a stop bar 6 is rotatably connected to the inner wall of the annular groove 5. A material leakage groove 7 is opened on the outer wall of the stop bar 6, and a through hole 8 is opened at one end of the stop bar 6. A drive connector is provided in the through hole 8, and one end of the drive connector is fixedly connected to the piston 3. A second three-way pipe 9 is provided at the bottom of the disinfection box 1, and both ends of the second three-way pipe 9 are connected to the disinfection box 1. A control valve 10 is fixedly connected to the inner wall of the second three-way pipe 9.

[0029] As can be seen from the above structure, by setting the piston 3 and the switch control component to work together, the switch control component can close or open one end of the first three-way pipe 2 after the piston 3 moves to a certain position, so that the piston 3 moves in reverse. And by setting the drive connector, the stop rod 6 can be driven to rotate when the piston 3 moves. When the stop rod 6 rotates, the leakage trough 7 located above the stop rod 6 rotates to the bottom. When the leakage trough 7 rotates to the bottom, the disinfectant powder will fall into the disinfection tank 1, completing the addition of disinfectant powder. In this way, the movement of the piston 3 controls the addition of disinfectant powder, and the movement of the piston 3 is related to the water flowing into the disinfection tank 1, so that the addition of disinfectant powder and water can be kept at a certain ratio, thereby avoiding the problem of the disinfectant powder concentration decreasing, thus weakening the disinfection effect, or avoiding the problem of excessive disinfectant addition, resulting in unnecessary resource consumption and cost waste.

[0030] Furthermore, the switch control assembly includes a housing 11 communicating with the first three-way pipe 2, and a stop 12 is slidably connected to the inner wall of the housing 11. An annular hole 13 is formed on one side wall of the stop 12, and a limit plate 14 is fixedly connected to one end of the stop 12. A first magnet 15 is fixedly connected to the other end of the stop 12. A clearance hole 16 and a through hole 17 are formed on one side wall of the piston 3, and a second magnet 18 is fixedly connected to the inner wall of the clearance hole 16. A connecting rod 19 is slidably connected to the inner wall of the through hole 17, and both ends of the connecting rod 19 are fixedly connected to the two limit plates 14 respectively. A material leakage opening is formed at the bottom of the housing 11. Hole 20; By setting the housing 11 and the stop block 12, etc., after the piston 3 moves to a certain position, the second magnet 18 attracts one of the first magnets 15, causing the first magnet 15 to move. The moving first magnet 15 can drive the stop block 12 to move. After the stop block 12 moves to a certain position, the annular hole 13 of this switch control component is connected to the leakage hole 20 and one end of the first three-way pipe 2. At this time, water will enter the other side of the piston 3 through the annular hole 13 and the leakage hole 20, thereby pushing the piston 3 to move in the opposite direction and completing the reversal of the piston 3. This allows the piston 3 to move back and forth in the disinfection box 1.

[0031] Furthermore, the drive connector includes a long rod 21 that is slidably connected to the inner wall of the through hole 8. The inner wall of the through hole 8 is provided with a spiral guide groove 22, and a protrusion 23 is provided in the spiral guide groove 22. One end of the protrusion 23 is fixedly connected to the long rod 21, and one end of the long rod 21 is fixedly connected to the piston 3. By setting the long rod 21 and the spiral guide groove 22 to work together, when the piston 3 moves, the piston 3 drives the long rod 21 to move. The moving long rod 21 drives the protrusion 23 to move. The moving protrusion 23 drives the stop rod 6 to rotate through the spiral guide groove 22. When the stop rod 6 rotates, the material leakage trough 7 located above the stop rod 6 rotates to the bottom. When the material leakage trough 7 rotates to the bottom, the disinfectant powder will fall into the disinfection box 1, completing the addition of disinfectant powder.

[0032] Furthermore, one end of the protrusion 23 is rotatably connected to a rotating block 24, and the sidewall of the rotating block 24 is slidably connected to the spiral guide groove 22. By setting the rotating block 24, the sliding friction between the protrusion 23 and the spiral guide groove 22 can be converted into rolling friction between the rotating block 24 and the spiral guide groove 22, thereby reducing the friction force.

[0033] Furthermore, the end of the baffle 6 away from the long rod 21 passes through the annular groove 5 and is rotatably connected to the inner wall of the disinfection box 1. A stirring rod 25 is fixedly connected to the outer wall of the baffle 6. By setting a baffle 6 with one end rotatably connected to the inner wall of the disinfection box 1, the stability of the rotation of the baffle 6 can be increased. And by setting a stirring rod 25 on the outer wall of the baffle 6, when the baffle 6 rotates, the rotating baffle 6 drives the stirring rod 25 to rotate. The rotating stirring rod 25 can stir the disinfectant powder solution, ensuring that the disinfectant powder and water can be fully mixed.

[0034] Furthermore, limit bars 26 are provided on both sides of the piston 3, and the limit bars 26 are fixedly connected to the inner wall of the disinfection box 1. By setting the limit bars 26, the position of the piston 3 can be limited.

[0035] Furthermore, a rubber sleeve 27 is fixedly fitted on the outer wall of the piston 3, and the outer wall of the rubber sleeve 27 is interference-fitted with the inner wall of the disinfection box 1. By setting the rubber sleeve 27, the sealing performance of the piston 3 can be increased.

[0036] Furthermore, the upper end of the conduit 4 is connected to a hopper 28; by setting the hopper 28, it is convenient to add disinfectant powder into the conduit 4.

[0037] In this invention, before use, one end of the first three-way pipe 2 is connected to the water inlet pipe, and one end of the second three-way pipe 9 is connected to the drain pipe. Then, disinfectant powder is added to the hopper 28, and the disinfectant powder added to the hopper 28 falls into the leakage trough 7 through the conduit 4.

[0038] In use, water enters the disinfection tank 1 on one side of the piston 3 through one end of the first three-way pipe 2, the annular hole 13, and the leakage hole 20. The water entering the disinfection tank 1 on one side of the piston 3 pushes the piston 3 to move. The moving piston 3 drives the long rod 21 to move. The moving long rod 21 drives the protrusion 23 to move. The moving protrusion 23 drives the baffle 6 to rotate through the spiral guide groove 22. When the baffle 6 rotates, the leakage groove 7 located above the baffle 6 rotates to the bottom. When the leakage groove 7 rotates to the bottom, the disinfectant powder will fall into the disinfection tank 1, completing the addition of disinfectant powder. This method of adding disinfectant powder ensures that the disinfectant powder and water are added in a strict ratio, thereby avoiding the problem of reduced disinfectant powder concentration, which weakens the disinfection effect, or avoiding excessive addition of disinfectant, which would lead to unnecessary resource consumption and cost waste.

[0039] Furthermore, when the baffle 6 rotates, the rotating baffle 6 drives the stirring rod 25 to rotate, and the rotating stirring rod 25 can stir the disinfectant powder solution, ensuring that the disinfectant powder and water can be fully mixed.

[0040] After the piston 3 moves to a certain position, the second magnet 18 attracts one of the first magnets 15, causing the first magnet 15 to move. The moving first magnet 15 can drive the stop block 12 to move. After the stop block 12 moves to a certain position, the annular hole 13 of this switch control component is connected to the leakage hole 20 and one end of the first three-way pipe 2. At this time, water will enter the other side of the piston 3 through the annular hole 13 and the leakage hole 20, thereby pushing the piston 3 to move in the opposite direction.

[0041] Furthermore, when the stop block 12 moves, the stop block 12 can drive another stop block 12 to move through the connecting rod 19. After the other stop block 12 moves to a certain position, the annular hole 13 and the leakage hole 20 on one side of the piston 3 are closed. At the same time, the control valve 10 on one side of the piston 3 is opened, so that when the piston 3 moves in the opposite direction, the water on one side of the piston 3 can be forced out through the opened control valve 10 and the second three-way pipe 9 to complete the circulation.

[0042] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
