Abstract
Description
Technical Field
[0001] This utility model belongs to the field of aquaculture equipment technology, specifically a water quality control device for rice-shrimp co-culture. Background Technology
[0002] Rice-crayfish co-culture is a three-dimensional ecological agricultural model that organically combines rice cultivation with crayfish farming. By digging shrimp ditches and installing escape prevention facilities in rice paddies, crayfish farming and rice cultivation can be carried out simultaneously in rice paddies.
[0003] Water quality control is necessary in rice-shrimp co-culture to ensure the water in the paddy fields is suitable for the growth of both rice and shrimp. This control focuses on key indicators such as dissolved oxygen, pH, and transparency. Existing technologies use water circulation to filter and circulate the water in the paddy fields, thereby reducing impurities and increasing dissolved oxygen levels. However, long-term observation has revealed that existing technologies typically pump water from near the paddy field bank, leading to uneven water pumping due to the distance between the pumped water and the opposite bank.
[0004] Therefore, this utility model provides a water quality control device for rice-shrimp co-culture. Utility Model Content
[0005] To overcome the shortcomings of existing technologies and solve at least one of the problems mentioned in the background technology, a water quality control device for rice-shrimp co-culture is proposed.

Through the above structure, the water tank, water pump, water suction pipe, water outlet pipe and drain pipe can work together to circulate and filter the water in the paddy field to improve the water quality. The water suction pipe and filter can draw water from the center of the paddy field, thereby reducing the uneven water pumping caused by drawing water from the edge of the paddy field in the prior art.
[0007] Preferably, the connecting assembly includes a lower chuck fixed to the top of the filter, an upper chuck fixed to the end of the pumping pipe, an upper clamp and a lower clamp mounted on the lower and upper chucks respectively, the upper clamp and the lower clamp being rotatably connected, a clamping plate fixed to the side wall of the upper clamp, and a screw hinged to the side wall of the lower clamp, with a locking nut threaded onto the screw. Through the above structure, the filter and the pumping pipe are connected together by the clamping action of the upper and lower clamps, thereby improving the convenience of installing and disassembling the pumping pipe and the filter.
[0008] Preferably, the support assembly includes a sleeve fixed to the bottom of the filter, a support plate threaded inside the sleeve, and multiple anchor rods fixed to the bottom of the support plate. With the above structure, the sleeve, support plate, and anchor rods can be positioned above the paddy field silt, thereby reducing the likelihood of the filter clogging due to contact with the silt. The threaded connection between the sleeve and the support plate can also improve the convenience of installation and disassembly.
[0009] Preferably, the microfiltration component includes a fixed box, which is fixedly connected inside the water tank. A baffle is installed inside the fixed box, and a fixed frame is connected to the baffle. A filter screen is installed inside the fixed frame, and positioning components are provided on the baffle and the fixed frame. With the above structure, the fixed box, fixed frame, and filter screen are set, and the water can be finely filtered in a secondary manner, thereby improving the water purification effect.
[0010] Preferably, the positioning component includes multiple positioning holes, which are formed on the fixed frame. A pair of handles are fixed to the top of the fixed frame, and multiple limiting rods are fixed to the top of the baffle. With the above structure, the positioning holes, handles, and limiting rods make it easy to remove the fixed frame and the filter screen from the fixed box, so as to facilitate the subsequent cleaning of the filter screen surface.
[0011] Preferably, the sterilization component includes a mounting base, which is detachably installed inside the water tank. Multiple ultraviolet lamps are mounted on the mounting base. With the above structure, the mounting base and ultraviolet lamps can sterilize the circulating water flow, further improving the water quality regulation effect. The detachable structure of the mounting base makes it convenient to remove the mounting base and ultraviolet lamps from the water tank for cleaning and maintenance later.

[0023] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0024] Specific implementation examples are given below.
[0025] like Figures 1 to 5As shown in the embodiment of this utility model, a water quality control device for rice-shrimp co-culture includes a water tank 1. A water pump 11 is fixedly connected to the side wall of the water tank 1. A water pump 12 is connected to the water pump 11. The water pump 12 is made of flexible hose. A water outlet pipe 13 is connected to the water pump 11. A drain pipe 14 is connected to the side wall of the water tank 1. A filter 15 is installed at the end of the water pump 12. A connecting component is provided on the water pump 12 and the filter 15. A support component is provided at the bottom of the filter 15. A microfiltration component and a sterilization component are provided inside the water tank 1. During operation, the filter 15 is connected to the water pump 12 through the connecting component. Then, the water pump 12 is pulled to place the filter 15 near the center of the rice paddy. Then, the water pump 11 is started to pump water from the rice paddy into the water pump 12. At this time, the filter 15 filters the water entering the pumping pipe 12, blocking the dead branches and leaves in the water outside the filter 15. Then, the water enters the water tank 1 from the outlet pipe 13, passes through the microfiltration component and the sterilization component, and is discharged from the drain pipe 14 and flows back into the paddy field. By circulating and filtering the water in the paddy field, suspended solids in the water can be removed, and the oxygen content in the water can be increased by the action of water flow, thereby playing a role in water quality regulation. Through the above structure, the water tank 1, water pump 11, pumping pipe 12, outlet pipe 13 and drain pipe 14 work together to circulate and filter the water in the paddy field, thereby improving the water quality. The pumping pipe 12 and the filter 15 can pump water from the center of the paddy field, thereby reducing the uneven pumping caused by pumping water from the edge of the paddy field in the prior art.
[0026] like Figure 3 As shown, the connecting assembly includes a lower chuck 2, which is fixedly connected to the top of the filter 15. An upper chuck 21 is fixedly connected to the end of the water pump pipe 12. An upper clamp 22 and a lower clamp 23 are installed on both the lower chuck 2 and the upper chuck 21. The upper clamp 22 and the lower clamp 23 are rotatably connected. A clamping plate 24 is fixedly connected to the side wall of the upper clamp 22, and a screw 25 is hinged to the side wall of the lower clamp 23. A locking nut 26 is threaded onto the screw 25. During operation, when connecting the filter 15 to the water pump pipe 12, the lower chuck 2 and the upper chuck 23 are connected to each other. 1. Fit tightly, then rotate the upper clamp 22 and lower clamp 23 to lock onto the lower chuck 2 and upper chuck 21. Then rotate the screw 25 to lock into the slot of the chuck plate 24. Then rotate the locking nut 26 to squeeze it against the surface of the chuck plate 24 to connect and fix the upper clamp 22 and lower clamp 23, thereby connecting the filter 15 and the water pumping pipe 12 together. Through the above structure, the filter 15 and the water pumping pipe 12 are connected together by the locking action of the upper clamp 22 and lower clamp 23, thereby improving the convenience of installing and disassembling the water pumping pipe 12 and the filter 15.
[0027] like Figure 2As shown, the support assembly includes a sleeve 3, which is fixed to the bottom of the filter 15. A support plate 31 is threadedly connected to the sleeve 3, and multiple anchor rods 32 are fixedly connected to the bottom of the support plate 31. During operation, after connecting the filter 15 to the pumping pipe 12, the support plate 31 and the sleeve 3 are tightened together by threads. Then, the anchor rods 32 are inserted into the paddy field. At this time, the filter 15 can be positioned above the paddy field silt. Through the above structure, by setting the sleeve 3, the support plate 31, and the anchor rods 32, the filter 15 can be positioned above the paddy field silt, thereby reducing the possibility of the filter 15 clogging due to contact with the silt. The threaded connection between the sleeve 3 and the support plate 31 can improve the convenience of installation and disassembly.
[0028] like Figure 4 and Figure 5 As shown, the microfiltration assembly includes a fixed box 4, which is fixedly connected inside the water tank 1. A baffle 41 is installed inside the fixed box 4, and a fixed frame 42 is connected to the baffle 41. A filter screen 43 is installed inside the fixed frame 42. Positioning components are provided on the baffle 41 and the fixed frame 42. During operation, the fixed frame 42 and the filter screen 43 are installed inside the fixed box 4 through the positioning components. When water flows into the water tank 1 from the outlet pipe 13, it will be filtered twice by the fixed frame 42. At this time, smaller particles or suspended solids in the water can be filtered out. The filtered water enters the water tank 1 through the bottom of the fixed box 4. Through the above structure, with the fixed box 4, the fixed frame 42 and the filter screen 43, the water can be finely filtered twice, thereby improving the water purification effect.
[0029] like Figure 5 As shown, the positioning component includes multiple positioning holes 5, which are formed on the fixed frame 42. A pair of handles 51 are fixedly connected to the top of the fixed frame 42, and multiple limiting rods 52 are fixedly connected to the top of the baffle 41. During operation, the fixed frame 42 and the filter screen 43 are lifted by holding the handles 51, and then the positioning holes 5 and the limiting rods 52 are aligned to install the fixed frame 42 and the filter screen 43 on the baffle 41. When it is necessary to clean the filter screen 43, the fixed frame 42 and the filter screen 43 can be lifted by holding the handles 51 to detach them from the limiting rods 52, and then the fixed frame 42 and the filter screen 43 can be taken out from the fixed box 4. Through the above structure, the positioning holes 5, handles 51 and limiting rods 52 are provided to facilitate the removal of the fixed frame 42 and the filter screen 43 from the fixed box 4, so as to facilitate the subsequent cleaning of the surface of the filter screen 43.
[0030] like Figure 4As shown, the sterilization component includes a mounting base 6, which is detachably installed inside the water tank 1. Multiple ultraviolet lamps 61 are installed on the mounting base 6. When the ultraviolet lamps 61 are powered on, they will generate ultraviolet light, which can sterilize the water in the water tank 1. Through the above structure, the mounting base 6 and the ultraviolet lamps 61 can sterilize the circulating water flow, further improving the water quality regulation effect. The detachable structure of the mounting base 6 makes it convenient to remove the mounting base 6 and the ultraviolet lamps 61 from the water tank 1 for cleaning and maintenance.
[0031] like Figure 1 As shown, the drain pipe 14 is located near the middle section of the water tank 1. With the above structure, the drain pipe 14 is located in the middle section of the water tank 1, which allows the water in the water tank 1 to rise to the position of the drain pipe 14 before being discharged. This can increase the retention time of water in the water tank 1, thereby improving the sterilization effect of the ultraviolet lamp 61 on the water.
[0032] Working principle: The filter 15 is connected to the pumping pipe 12 via a connecting assembly. The pumping pipe 12 is then pulled to place the filter 15 near the center of the paddy field. The water pump 11 is then started to pump water from the paddy field into the pumping pipe 12. The filter 15 filters the water entering the pumping pipe 12, blocking dead leaves and branches from entering the filter. The water then flows through the outlet pipe 13 into the water tank 1, passing through the microfiltration and sterilization components before being discharged through the drain pipe 14 and returning to the paddy field. This process effectively treats the water in the paddy field. Circulating filtration can remove suspended solids from water and increase the oxygen content through water flow, thus regulating water quality. When connecting the filter 15 to the pump pipe 12, ensure the lower chuck 2 and upper chuck 21 are tightly fitted together. Then, rotate the upper clamp 22 and lower clamp 23 to engage with the lower chuck 2 and upper chuck 21. Next, rotate the screw 25 to engage with the slot in the clamping plate 24. Finally, rotate the locking nut 26 to tighten it against the surface of the clamping plate 24, thus connecting and fixing the upper clamp 22 and lower clamp 23. The filter 15 is connected to the pumping pipe 12. After connecting the filter 15 to the pumping pipe 12, the support plate 31 and the sleeve 3 are tightened with threads. Then, the anchor rod 32 is inserted into the paddy field, so that the filter 15 is positioned above the paddy field silt. The fixing frame 42 and the filter screen 43 are installed in the fixing box 4 through the positioning assembly. When water flows into the water tank 1 from the outlet pipe 13, it will be filtered twice through the fixing frame 42. At this time, smaller particles or suspended solids in the water can be filtered out. The filtered water is then filtered through the fixing frame 42. The bottom of the box 4 enters the water tank 1. By holding the handle 51, the fixing frame 42 and the filter screen 43 are lifted up. Then, the positioning hole 5 is aligned with the limiting rod 52, and the fixing frame 42 and the filter screen 43 are installed on the baffle 41. When the filter screen 43 needs to be cleaned, the fixing frame 42 and the filter screen 43 can be pulled up by holding the handle 51 to detach them from the limiting rod 52. Then the fixing frame 42 and the filter screen 43 can be taken out from the fixing box 4. When the ultraviolet lamp 61 is powered on, it will generate ultraviolet light, which can sterilize the water in the water tank 1.
