Description

Technical Field

[0001] This utility model belongs to the field of drainage devices, specifically a bottom drainage device for rice-fish farming. Background Technology

[0002] Rice-fish farming is an ecological agricultural model that combines rice cultivation and aquaculture, aiming to improve the efficiency of land and water resource utilization while promoting ecological balance and sustainable agricultural development. In this model, drainage systems play a crucial role, not only ensuring the drainage needs of the farmland but also preventing fish and aquatic plants from being washed away by the water flow, thus ensuring the stability and effectiveness of the farming system.

[0003] In existing technologies, bottom drainage devices for rice-fish farming are prone to clogging of the outlet due to the large amount of silt inside the wastewater. This makes subsequent cleaning very troublesome. Therefore, this solution incorporates a bottom drainage device, which can filter wastewater and make silt cleaning much easier. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a bottom drainage device for rice-fish farming, which solves the problem that existing bottom drainage devices for rice-fish farming are prone to clogging of the outlet due to the large amount of silt inside when the sewage is discharged, and the subsequent cleaning is very troublesome.

[0005] A bottom drainage device for rice-fish farming includes a filter and a drain pipe. The drain pipe is installed on one side of the filter, and an inlet pipe is installed at one end of the drain pipe via a flange. A fixing block is fixedly connected to the surface of the inlet pipe. The fixing block is fixedly connected to a filter frame. An inclined filter plate is fixedly connected to the inner side wall of the filter frame. A first handle is fixedly connected to the surface of the filter frame, and the bottom of the side wall of the filter frame is attached to a block fixed to the inner wall of the filter.

[0006] Preferably, the inner wall of the filter frame is an inclined structure, and the inclined filter plate is an inclined filter screen with a supporting structure installed, and the inclined filter plate is located below the outlet of the inlet pipe.

[0007] Preferably, the filter has a gate assembly installed on the side wall away from the drain pipe.

[0008] Preferably, the gate assembly includes a gate, a gate mesh, a protrusion, and a second handle. The gate is installed on the inner side of the filter, and the gate mesh is installed on the outer side. The bottom side of the gate and the gate mesh is fixedly connected to a protrusion, and the top of the gate and the gate mesh is fixedly connected to a second handle.

[0009] Preferably, the gate is a solid structure and the gate mesh is made of iron filter screen.

[0010] Preferably, the outer side of the gate and the gate mesh is provided with a buckle, which is movably installed on the inner wall of the filter via a rotating shaft.

[0011] Compared with existing technologies, this utility model has the following advantages: By incorporating a removable and detachable filter frame, when paddy field wastewater containing silt is discharged, the wastewater can be filtered through the filter frame, and the sludge in the wastewater can be filtered and accumulated, facilitating subsequent sludge cleaning. Simultaneously, this device is also equipped with a double gate, allowing the filter to achieve both dual filtration and wastewater storage and settling. This utility model has a simple structure and can filter discharged paddy field wastewater, thereby avoiding direct discharge of sludge, which not only leads to siltation at the outlet but also makes subsequent sludge cleaning more troublesome.

[0016] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0017] like Figure 1-3 As shown, this utility model provides a bottom drainage device for rice-fish farming, including a filter 1 and a drain pipe 2. The drain pipe 2 is installed on one side of the filter 1, and an inlet pipe 3 is installed at one end of the drain pipe 2 through a flange. A fixing block 4 is fixedly connected to the surface of the inlet pipe 3. The fixing block 4 is fixedly connected to a filter frame 5. An inclined filter plate 6 is fixedly connected to the inner side wall of the filter frame 5. A first handle 7 is fixedly connected to the surface of the filter frame 5, and the bottom of the side wall of the filter frame 5 is attached to a baffle 8 fixed to the inner wall of the filter 1. The filter frame 5 can filter the water containing silt discharged from the paddy field.

[0018] The inner wall of the filter frame 5 is inclined, and the inclined filter plate 6 is an inclined filter screen with a support structure. The inclined filter plate 6 is located below the outlet of the inlet pipe 3. The inclined filter plate 6 can transport the sludge and sewage discharged from the inlet pipe 3 to the bottom of the filter frame 5, so that the water with sludge discharged from the paddy field can gradually accumulate from the bottom.

[0019] The filter 1 has a gate assembly installed on the side wall away from the drain pipe 2. The gate assembly includes a gate 9, a gate mesh 10, a protrusion 11, and a second handle 13. The gate 9 is installed on the inner side of the filter 1, and the gate mesh 10 is installed on the outer side. The protrusion 11 is fixedly connected to the bottom side of the gate 9 and the gate mesh 10, and the second handle 13 is fixedly connected to the top of the gate 9 and the gate mesh 10. The gate assembly can perform multiple functions as needed. When the gate mesh 10 is pulled up, the gate mesh 10 can further filter the silt water from the paddy field.

[0020] The gate 9 is a solid structure, and the gate screen 10 is made of iron filter screen, which allows the gate screen 10 to further filter the paddy field water.

[0021] The gate 9 and the screen 10 are provided with a buckle 12 on their outer side. The buckle 12 is movably installed on the inner wall of the filter 1 via a rotating shaft. When the gate 9 and the screen 10 are pulled up, the protrusion 11 presses the buckle 12 so that one end of the buckle 12 rotates until the buckle 12 locks the protrusion 11, thereby fixing the pulled-up gate 9 and the screen 10.

[0022] Working principle: The flange at one end of the inlet pipe 3 is installed together with the flange of the drain pipe 2. The water discharged through the drain pipe 2 is transported to the inlet pipe 3. The inlet pipe 3 transports the paddy field water to the inclined filter plate 6. The inclined filter plate 6 discharges the silt and debris to the bottom of the filter frame 5. When too much silt accumulates in the filter frame 5, the first handle 7 is lifted to remove and clean the silt in the filter frame 5. Then it is put back in its original position. The paddy field water discharged into the filter 1 is filtered by the filter frame 5 and then transported into the interior of the filter 1. If it is necessary to discharge the filtered water in the filter 1 directly, the gate 9 is pulled up by hand, so that the protrusion 11 on one side of the gate 9 presses the buckle 12, causing the buckle 12 to rotate until the buckle 12 locks the protrusion 11, thereby fixing the gate 9. At this time, the water discharged into the well is filtered by the filter frame 5 and transported into the interior of the filter 1. It is then filtered by the gate screen 10 and transported to the outside. If it is necessary to clean the silt inside the filter 1, the inner wall of the gate screen 10 is pulled up.

[0023] The embodiments of this utility model are given for the purpose of illustration and description. Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this utility model. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this utility model.
