Description

Technical Field

[0001] This invention relates to the field of aquaculture technology, specifically to a sterilizer for aquaculture. Background Technology

[0002] In aquaculture, pond disinfection is an indispensable part. Reasonable disinfection measures can effectively curb the breeding of pathogens, insects and other harmful organisms, and also help optimize the aquatic ecological environment. Regular disinfection is particularly important for the healthy growth of aquatic animals such as fish, shrimp and crabs. Commonly used pond disinfection methods include bleaching powder disinfection, quicklime disinfection, tea seed cake disinfection, ultraviolet lamp disinfection, and copper ion disinfection.

[0003] Existing methods for disinfecting aquaculture ponds involve spraying disinfectant at depths of tens or even hundreds of centimeters, requiring precise control of the amount sprayed per acre and maintaining uniformity throughout the acre. These variables all require human intervention, which is difficult and dangerous on water, prone to accidents, and most disinfectants pose potential health risks. Therefore, a sterilization device for aquaculture is proposed. Summary of the Invention

[0004] The purpose of this invention is to address the problems that existing disinfection methods for aquaculture ponds require manual control of variables, which makes water operations difficult, dangerous, and prone to accidents, and that most disinfectants pose potential health hazards. This invention provides a sterilizer for aquaculture.

[0005] To achieve the above objectives, the present invention specifically adopts the following technical solution: A sterilization device for aquaculture includes an unmanned transport tray. A disinfectant tank and a weighing device are fixedly installed on the top of the unmanned transport tray. A weighing frame and a discharge valve are fixedly installed at the bottom of the disinfectant tank. The weighing frame is fixedly installed on top of the weighing device. A mixing chamber is provided inside the unmanned transport tray. The bottom end of the discharge valve extends into the interior of the mixing chamber. Pump chambers are provided on both sides of the mixing chamber. The bottom of the two pump chambers has a common bottom side chamber. A water pump and a drain pump are fixedly installed inside the pump chambers, respectively. A water inlet pipe is fixedly installed at the inlet end of the water pump, and one end of the water inlet pipe extends to the outside of the unmanned transport tray. A water drain pipe is fixedly installed at the outlet end of the water pump, and a mixing pump pipe is fixedly installed at the inlet end of the water pump. One end of both the water drain pipe and the mixing pump pipe extends into the interior of the mixing chamber. A three-way valve is fixedly installed at the outlet end of the water pump, and a mixing drain pipe is fixedly installed at one end of the three-way valve. An annular drain pipe is fixedly installed inside the mixing chamber, and one end of the mixing drain pipe is connected to the annular drain pipe. Multiple evenly distributed external drain pipes are fixedly installed around the annular drain pipe, and one end of each external drain pipe extends to the outside of the unmanned transport disk. Propeller assemblies are fixedly installed on both sides of the unmanned transport disk.

[0006] Furthermore, a hanging compartment is provided at the bottom of the mixing compartment, and a diversion drain pipe is fixedly installed at the other end of the three-way valve. One end of the diversion drain pipe passes through the pump compartment and the mixing compartment in sequence and extends into the interior of the hanging compartment. A hanging hose is fixedly installed at one end of the diversion drain pipe. A cleaning through hole is opened at the bottom of the hanging compartment. The bottom end of the hanging hose passes through the cleaning through hole and extends to the bottom of the unmanned transport tray. Multiple evenly distributed drain holes are opened on the periphery of the hanging hose.

[0007] Furthermore, four pressure roller brackets are fixedly installed inside the hoisting compartment. The four pressure roller brackets are paired in pairs. Pressure roller shafts are rotatably installed on the two pressure roller brackets located on the same side. Each pressure roller shaft is fixedly fitted with a lifting pressure roller that contacts the hoisting hose. The two lifting pressure rollers are located on both sides of the hoisting hose. A gearbox and a hoisting motor are fixedly installed inside the hoisting compartment. One end of each of the two pressure roller shafts extends into the interior of the gearbox and is fixedly fitted with a reverse gear. The two reverse gears mesh with each other. The output end of the hoisting motor is drivenly connected to one of the pressure roller shafts.

[0008] Furthermore, the interior of the suspension hose is fixedly equipped with multiple reinforcing rings evenly distributed from top to bottom, and the interior of the suspension hose is fixedly equipped with multiple reinforcing cables evenly distributed, the reinforcing cables being sequentially fixedly connected to the multiple reinforcing rings.

[0009] Furthermore, a sealing plate adapted to the cleaning through hole is fixedly installed at the bottom end of the hanging hose.

[0010] Furthermore, a convergence cam is provided at the bottom of the bottom side chamber, and the bottom end of the water pumping pipe extends into the interior of the convergence cam and is fixedly installed with a filter screen. A turbine frame is fixedly installed inside the convergence cam, and a vertically arranged turbine shaft is rotatably installed on the turbine frame. A cleaning scraper that contacts the bottom of the filter screen is fixedly installed at the top of the turbine shaft, and a turbine assembly is fixedly installed at the bottom of the turbine shaft.

[0011] Furthermore, a disinfection riser is provided on one side of the unmanned transport tray, an underwater support is fixedly installed at the bottom of the disinfection riser, an assembly frame is fixedly sleeved on the disinfection riser, and a storage compartment adapted to the unmanned transport tray is fixedly installed on one side of the assembly frame.

[0012] Furthermore, an ultraviolet germicidal lamp and a copper ion generator are fixedly installed inside the disinfection riser, and multiple evenly distributed flow tubes are fixedly installed on the bottom periphery of the disinfection riser, all of which are connected to the inside of the disinfection riser.

[0013] The beneficial effects of this invention are as follows: 1. This invention mixes disinfectant and raw water, and finally sprays it into the water body through various external drain pipes for disinfection. At this time, the two propeller assemblies stop operating, and the reaction force of the spray from the fan-shaped external drain pipes will drive the unmanned transport disk to rotate in its original position, thereby improving the range and uniformity of disinfectant spraying. Afterwards, the unmanned transport disk will successively put disinfectant into various parts of the water body, realizing unmanned, precise and uniform dispensing. 2. By setting up a hanging hose, when the unmanned transport tray travels to the deep water area, the unmanned transport tray first releases disinfectant into the shallow water layer through the external drainage pipe. Then, the hanging motor drives the hanging hose to be lowered until the designated depth is reached. At this time, the three-way valve switches the channel so that the disinfectant is released into the deep water layer through the drainage hole, achieving uniform vertical release and ensuring the disinfection effect. After the release is completed, the lifting pressure roller can retract the hanging hose upwards again. 3. By setting up a cleaning scraper, the converging cam can constrict the water flow. When the raw water enters the mixing chamber through the converging cam and the water pumping pipe, the filter screen can filter the water flow. The incoming water flow will drive the water turbine assembly inside the converging cam to rotate, thereby driving the cleaning scraper to rotate and scrape the bottom of the filter screen through the water turbine shaft, preventing the filter screen from clogging. 4. By setting up disinfection risers, this invention allows disinfection risers to be deployed at various locations according to different underwater conditions. While the disinfectant is being delivered by the unmanned transport tray, the ultraviolet germicidal lamps inside the disinfection risers, in conjunction with the copper ion generator, perform dual disinfection and purification of the nearby water by ultraviolet irradiation and copper ion generation, thereby improving the disinfection effect of the water.

[0014] 5. By setting up a storage compartment, the unmanned transport tray can drive to the nearest disinfection riser and enter the storage compartment for parking after disinfection. At the same time, the top of the storage compartment can be equipped with disinfectant dosing tanks or solar charging equipment, so that the unmanned transport tray can replenish disinfectant and power during parking, thereby improving its endurance.

They are only for the convenience of describing the present 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 limiting the present invention.

[0020] like Figures 1 to 9 As shown, a sterilizer for aquaculture includes an unmanned transport tray 1, such as... Figure 2 , Figure 3 , Figure 4 As shown, a disinfectant tank 2 and a weighing device 25 are fixedly installed on the top of the unmanned transport tray 1. A weighing frame 3 and a discharge valve 4 are fixedly installed on the bottom of the disinfectant tank 2. The weighing frame 3 is fixedly installed on the top of the weighing device 25. A mixing chamber 101 is provided inside the unmanned transport tray 1. The bottom end of the discharge valve 4 extends into the interior of the mixing chamber 101. Pump chambers 102 are provided on both sides of the mixing chamber 101. The bottom of the two pump chambers 102 is provided with the same bottom side chamber 103. Inside compartment 102, a water pump 5 and a drainage pump 8 are fixedly installed. A water pumping pipe 6 is fixedly installed at the inlet of water pump 5, with one end extending to the outside of the unmanned transport tray 1. A water drain pipe 7 is fixedly installed at the outlet of water pump 5. A mixing pumping pipe 9 is fixedly installed at the inlet of drainage pump 8. One end of both the water drain pipe 7 and the mixing pumping pipe 9 extends into the interior of the mixing compartment 101. A convergence cam 104 is provided at the bottom of the bottom side compartment 103. Figure 5 , Figure 6 As shown, the bottom end of the water pumping pipe 6 extends into the interior of the converging cam 104 and is fixedly installed with a filter screen 26. A turbine frame 27 is fixedly installed inside the converging cam 104. A vertically arranged turbine shaft 28 is rotatably installed on the turbine frame 27. A cleaning scraper 29 that contacts the bottom of the filter screen 26 is fixedly installed at the top of the turbine shaft 28. A turbine assembly 30 is fixedly installed at the bottom of the turbine shaft 28.

[0021] In this embodiment, one end of the water pumping pipe 6 passes through the pump chamber 102, the mixing chamber 101 and the bottom side chamber 103 in sequence and extends into the interior of the converging cam 104. The opening of the converging cam 104 faces downward and communicates with the outside. The converging cam 104 protrudes into the interior of the bottom side chamber 103.

[0022] More specifically, when using this aquaculture sterilizer, sufficient amounts of disinfectants such as bleaching powder and quicklime are first added to the disinfectant tank 2. The propeller assemblies 14 on both sides of the unmanned transport disc 1 propel the unmanned transport disc 1 across the aquaculture field, pond, or other water bodies. The discharge valve 4 at the bottom of the disinfectant tank 2 opens to discharge the disinfectant. Simultaneously, the weighing device 25 weighs the disinfectant tank 2 in real time, and the amount of disinfectant dispensed at one time is precisely controlled by the difference in weight. At the same time, the water pump 5 directly draws water from the water body through the water pumping pipe 6. Raw water is drawn in and fed into the mixing chamber 101 through the water drain pipe 7 to mix with disinfectant. The converging cam 104 can constrict the water flow. When the raw water enters the mixing chamber 101 through the converging cam 104 and the water pumping pipe 6, the filter screen 26 can filter the water flow. The incoming water flow will drive the water turbine assembly 30 inside the converging cam 104 to rotate, thereby driving the cleaning scraper 29 to rotate and scrape the bottom of the filter screen 26 through the water turbine shaft 28, preventing the filter screen 26 from clogging.

[0023] like Figure 2 , Figure 3 As shown, specifically, a three-way valve 10 is fixedly installed at the outlet end of the drainage pump 8, a mixing drainage pipe 11 is fixedly installed at one end of the three-way valve 10, an annular drainage pipe 12 is fixedly installed inside the mixing chamber 101, one end of the mixing drainage pipe 11 is connected to the annular drainage pipe 12, and multiple evenly distributed external drainage pipes 13 are fixedly installed around the annular drainage pipe 12. One end of each external drainage pipe 13 extends to the outside of the unmanned transport disk 1, and propeller assemblies 14 are fixedly installed on both sides of the unmanned transport disk 1.

[0024] In this embodiment, the outer ends of the first external drain pipe 13 are arranged in a fan shape.

[0025] More specifically, after mixing for a period of time, the discharge valve 4 and the water pump 5 are closed in sequence, ending the discharge and mixing process. The drain pump 8 then draws the mixed liquid from the mixing chamber 101 through the mixing drain pipe 9 and transports it through the three-way valve 10, the mixing drain pipe 11, and the annular drain pipe 12. Finally, it is sprayed into the water body through each external drain pipe 13 for disinfection. At this time, the two propeller assemblies 14 stop operating, and the reaction force of the mixed liquid sprayed outward from each external drain pipe 13 arranged in a fan shape will drive the unmanned transport disk 1 to rotate in its original position, thereby improving the range and uniformity of disinfectant spraying. Afterward, the unmanned transport disk 1 will successively put disinfectant into various parts of the water body, realizing unmanned, precise, and uniform dispensing.

[0026] like Figure 3 , Figure 7 , Figure 8As shown, specifically, a hanging compartment 105 is provided at the bottom of the mixing compartment 101. A diversion drain pipe 15 is fixedly installed at the other end of the three-way valve 10. One end of the diversion drain pipe 15 passes through the pump compartment 102 and the mixing compartment 101 sequentially and extends into the interior of the hanging compartment 105. A hanging hose 16 is fixedly installed at one end of the diversion drain pipe 15. A cleaning through-hole is provided at the bottom of the hanging compartment 105. The bottom end of the hanging hose 16 passes through the cleaning through-hole and extends to the bottom of the unmanned transport tray 1. Multiple evenly distributed drain holes 1601 are provided around the hanging hose 16. Figure 1 , Figure 2 As shown, four pressure roller brackets 17 are fixedly installed inside the hoisting compartment 105. The four pressure roller brackets 17 are paired in pairs. Pressure roller shafts 18 are rotatably installed on the two pressure roller brackets 17 located on the same side. Lifting pressure rollers 19 that are in contact with the hoisting hose 16 are fixedly sleeved on the pressure roller shafts 18. The two lifting pressure rollers 19 are located on both sides of the hoisting hose 16. A gearbox 20 and a hoisting motor 22 are fixedly installed inside the hoisting compartment 105. One end of each of the two pressure roller shafts 18 extends into the interior of the gearbox 20 and is fixedly sleeved with a reverse gear 21. The two reverse gears 21 mesh with each other. The output end of the hoisting motor 22 is driven by one of the pressure roller shafts 18.

[0027] In this embodiment, an elastic rubber ring can be installed inside the cleaning through hole. When the water pumping pipe 6 is retracted upwards, the elastic rubber ring scrapes the outer layer of the hanging hose 16 to reduce the mixing of debris.

[0028] More specifically, when the unmanned transport tray 1 travels to the deep water area, it first releases disinfectant into the shallow water layer through the external drain pipe 13. Then, the hanging motor 22 inside the hanging compartment 105 starts to drive the pressure roller shaft 18 to rotate, which in turn drives the lifting pressure roller 19 to rotate in the opposite direction through the meshing reverse gear 21. This drives the hanging hose 16 stored inside the hanging compartment 105 to descend, allowing the hanging hose 16 to fall continuously through the cleaning sliding hole until it reaches the designated depth. At this time, the three-way valve 10 switches the channel, allowing the drain pump 8 to release disinfectant into the diversion drain pipe 15, and then release it into the deep water layer through the various drain holes 1601 on the hanging hose 16, achieving uniform vertical release and ensuring the disinfection effect. After the release is completed, the lifting pressure roller 19 can retract the hanging hose 16 upwards again.

[0029] like Figure 2 As shown, specifically, a sealing plate 31 adapted to the cleaning through hole is fixedly installed at the bottom end of the hanging hose 16.

[0030] More specifically, by setting up the sealing plate 31, the sealing plate 31 can straighten the hanging hose 16, preventing the hanging hose 16 from swaying with the water flow underwater and affecting the disinfectant application effect. At the same time, after the hanging hose 16 is stored, the sealing plate 31 seals the bottom of the cleaning hole, improving the stability of storage.

[0031] like Figure 8 As shown, specifically, multiple reinforcing rings 23 are evenly distributed from top to bottom inside the hanging hose 16, and multiple reinforcing cables 24 are evenly distributed inside the hanging hose 16. The reinforcing cables 24 are sequentially and fixedly connected to the multiple reinforcing rings 23.

[0032] More specifically, by setting up reinforcing rings 23 and reinforcing cables 24, the reinforcing rings 23 and reinforcing cables 24 can improve the structural strength of the suspension hose 16, so that the suspension hose 16 can stably suspend the sealing plate 31 and prevent the suspension hose 16 from being cut by underwater debris. At the same time, they can also provide internal support for the suspension hose 16, preventing the suspension hose 16 from being crushed by the lifting pressure roller 19, and allowing the lifting pressure roller 19 to squeeze the suspension hose 16 to obtain sufficient friction.

[0033] like Figure 1 , Figure 9 As shown, specifically, a disinfection riser 32 is provided on one side of the unmanned transport tray 1, an underwater support 33 is fixedly installed at the bottom end of the disinfection riser 32, an assembly frame 34 is fixedly sleeved on the disinfection riser 32, and a storage compartment 35 adapted to the unmanned transport tray 1 is fixedly installed on one side of the assembly frame 34.

[0034] In this embodiment, both ends of the disinfection riser 32 are tightened with PVC caps, and the ultraviolet germicidal lamp 36 and the copper ion generator 37 are fixedly assembled with the disinfection riser 32 through the PVC caps, making subsequent maintenance, installation and disassembly more convenient and simple.

[0035] More specifically, by setting up disinfection risers 32, disinfection risers 32 can be deployed at various locations according to different underwater conditions. While the unmanned transport tray 1 is dispensing disinfectant, the ultraviolet germicidal lamps 36 inside the disinfection risers 32, together with the copper ion generator 37, perform dual disinfection and purification of the nearby water by ultraviolet irradiation and copper ion generation, thereby improving the disinfection effect of the water.

[0036] like Figure 9 As shown, specifically, an ultraviolet germicidal lamp 36 and a copper ion generator 37 are fixedly installed inside the disinfection riser 32, and multiple evenly distributed flow tubes 38 are fixedly installed on the bottom periphery of the disinfection riser 32, all of which are connected to the inside of the disinfection riser 32.

[0037] More specifically, by setting up a storage compartment 35, after disinfection, the unmanned transport tray 1 can drive to the nearest disinfection riser 32 and enter the storage compartment 35 for parking. At the same time, the top of the storage compartment 35 can be equipped with disinfectant dosing tanks or solar charging equipment, so that the unmanned transport tray 1 can replenish disinfectant and power during parking, thereby improving its endurance.

[0038] In summary: Before disinfection: Sufficient bleaching powder, quicklime and other disinfectants are added to the disinfectant tank 2. The propeller assemblies 14 on both sides of the unmanned transport disk 1 propel the unmanned transport disk 1 to navigate on the water bodies such as aquaculture fields and ponds. The discharge valve 4 at the bottom of the disinfectant tank 2 is opened to discharge the disinfectant. At the same time, the weighing device 25 weighs the disinfectant tank 2 in real time. The amount of disinfectant added at one time is precisely controlled by the change in the difference between the weights. Meanwhile, the water pump 5 directly draws raw water from the water body through the water body pumping pipe 6 and inputs it into the mixing chamber 101 through the water body drain pipe 7 to mix with the disinfectant. Disinfection in shallow water: After mixing for a period of time, the feeding valve 4 and the water pump 5 are closed in sequence to end the feeding and mixing. The drainage pump 8 starts to draw the mixed liquid from the mixing chamber 101 through the mixing water pipe 9 and transport it through the three-way valve 10, the mixing drainage pipe 11, and the ring drainage pipe 12. Finally, it is sprayed into the water body for disinfection through each external drainage pipe 13. At this time, the two propeller assemblies 14 stop operating. The reaction force of the mixed liquid sprayed outward by each external drainage pipe 13 arranged in a fan shape will drive the unmanned transport plate 1 to rotate in the original position. After that, the unmanned transport plate 1 will successively put disinfectant into various parts of the water body to achieve unmanned, precise and uniform dispensing. Disinfection in deep water: When the unmanned transport tray 1 travels to the deep water area, the unmanned transport tray 1 first releases disinfectant into the shallow water layer through the external drainage pipe 13. Then, the hanging motor 22 drives the hanging hose 16 to be lowered until the designated depth is reached. At this time, the three-way valve 10 switches the channel so that the drainage pump 8 can release the disinfectant into the diversion drainage pipe 15, and then release it into the deep water layer through the drainage holes 1601 on the hanging hose 16 to achieve uniform vertical release. After the release is completed, the lifting pressure roller 19 retracts the hanging hose 16 upwards again. After disinfection: The unmanned transport tray 1 can drive to the nearest disinfection riser 32 and enter the storage compartment 35 to dock, replenish disinfectant and power. At the same time, the ultraviolet germicidal lamp 36 inside the disinfection riser 32, together with the copper ion generator 37, performs dual disinfection and purification of the nearby water by ultraviolet irradiation and copper ion generation.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention.
