Detailed Embodiment

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 - 3 , the present utility model provides a technical solution: a drainage device for crab breeding in paddy fields, including:

[0024] Stable pressure regulating mechanism 100, the stable pressure regulating mechanism 100 includes a stable box 101. A first piston cylinder 104 and a second piston cylinder 105 are arranged on the upper surface of the stable box 101. A voltage transformation component is arranged in the first piston cylinder 104, and a connecting member 200 is arranged in the second piston cylinder 105;

[0025] One end of the connecting member 200 is installed with an impurity removal mechanism 300 and a drainage mechanism 400. The impurity removal mechanism 300 is arranged on the periphery of the drainage mechanism 400;

[0026] The impurity removal mechanism 300 includes an electric push rod 301. The telescopic end of the electric push rod 301 is fixedly connected with a collar 302. A plurality of support rods 303 are fixedly connected to the lower surface of the collar 302. The lower ends of the plurality of support rods 303 are all fixedly connected with a cleaning ring 304 for removing impurities.

[0027] The voltage transformation component includes an adjustable distance screw 106, an adjustable distance sleeve 107 and a first piston plate 108. The adjustable distance sleeve 107 is fixedly connected to the upper surface of the first piston plate 108. The adjustable distance screw 106 is rotatably connected to the upper end of the first piston cylinder 104 and is threadedly connected with the adjustable distance sleeve 107. By rotating the adjustable distance screw 106 and threadedly connecting it with the adjustable distance sleeve 107, it is convenient to adjust the height of the first piston plate 108, so as to adjust the liquid level drop of the medium (which can be water) in the first piston cylinder 104. At the same time, when the volume remains unchanged, the liquid level in the second piston cylinder 105 rises, so as to realize the height adjustment of the connecting member 200 and facilitate the adjustment of the drainage height, improving the efficiency of height adjustment of the drainage mechanism 400.

[0028] Two telescopic sleeve rods 109 are fixedly connected to the upper surface of the first piston plate 108. The upper ends of the two telescopic sleeve rods 109 are fixedly connected to the top of the inner cavity of the first piston cylinder 104. A runner 110 is fixedly connected to the upper end of the adjustable distance screw 106. By restricting the position of the first piston plate 108 through the telescopic sleeve rod 109, it is possible to prevent the adjustable distance sleeve 107 from rotating with the adjustable distance screw 106, facilitating the height adjustment of the first piston plate 108.

[0029] The connecting member 200 includes a right-angle bending plate 201 and a piston rod 202. The lower end of the piston rod 202 penetrates through the second piston cylinder 105 and is fixedly connected with a second piston plate 203. The second piston plate 203 is slidably connected to the inner cavity of the second piston cylinder 105. The inner diameter of the second piston cylinder 105 is smaller than the inner diameter of the first piston cylinder 104. Thus, when the first piston plate 108 descends, the lifting efficiency of the second piston plate 203 can be accelerated, facilitating the height adjustment of the drainage mechanism 400 and improving the operation convenience.

[0030] A plurality of connecting rods 205 are fixedly connected to the lower surface of the right-angle bending plate 201, and a limiting ring 204 which is slidably sleeved outside the second piston cylinder 105 is fixedly connected to the lower surface of the plurality of connecting rods 205. The stability of the lifting of the piston rod 202 is improved through the plurality of connecting rods 205 and the limiting ring 204, so that the connecting member 200 improves the stability of the lifting of the drainage mechanism 400.

[0031] The drainage mechanism 400 includes a drainage main pipe 401 fixedly connected to one side of the right-angle bending plate 201. A connecting secondary pipe is fixedly connected to the upper end of the drainage main pipe 401. A connecting groove 402 is opened at the lower end of the inner cavity of the drainage main pipe 401. A filter net cover 403 is threadedly connected in the connecting groove 402. A plurality of partition plates 404 are fixedly connected to the lower surface of the filter net cover 403. The connecting secondary pipe facilitates the connection of an external water pump pipeline, so as to facilitate the extraction of water in the paddy field. At the same time, the filter net cover 403 is convenient for disassembly and assembly. The outer diameter of the filter net cover 403 is the same as the inner diameter of the cleaning ring 304, which is convenient for the cleaning ring 304 to quickly clean the sundries on the outer surface of the filter net cover 403, so as to ensure smooth water flow.

[0032] Support side plates 102 are fixedly connected to both lower ends of the stability box 101. A plurality of ground cone inserting rods 103 are fixedly connected to the lower surface of the support side plates 102. The contact area with the paddy field ridge is increased through the support side plates 102, so as to improve the stability of the device. At the same time, the ground cone inserting rods 103 are inserted into the ridge to prevent the device from shaking and tipping during the drainage process, and the service life of the device is improved.

[0033] During use, the whole device is placed on the paddy field ridge or in the paddy field according to the drainage needs. Rotate the runner 110 to drive the distance-adjusting screw rod 106 to rotate. The rotation of the distance-adjusting screw rod 106 is changed into the lifting of the distance-adjusting sleeve 107, so that the first piston plate 108 compresses the medium in the first piston cylinder 104, and the medium enters the second piston cylinder 105 under the condition of constant volume, and the speed of the medium entering the second piston cylinder 105 is accelerated through different inner diameters, and the adjustment of the height of the second piston plate 203 is accelerated, so as to facilitate the adjustment of the depth of the drainage main pipe 401 entering the paddy field water, so as to control the drainage height. After connecting the pipeline of the water pump to the connecting secondary pipe, start the water pump, so as to realize the drainage of the water in the paddy field, and drive the collar 302 to lift through the electric push rod 301. Driven by the support rod 303, the cleaning ring 304 slides up and down on the outer wall of the filter net cover 403, so as to realize the cleaning of the sundries on the filter net cover 403, prevent the sundries from being adsorbed on the filter net cover 403 again along with the water flow, and ensure smooth drainage.

[0034] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
