[0002] During shrimp farming, due to the high density of farming and the large amount of feed, a large amount of residual bait and feces will be produced. At present, shrimp farming ponds often use central sewage discharge facilities to discharge sewage. During the farming process, a large amount of residual bait and feces will be produced, and a large number of shrimps will molt, which will cause the sewage screen to be blocked. The residual feces, residual bait, shrimp shells, etc. are easy to breed various bacteria, leading to an increase in the content of nitrite and ammonia nitrogen in the farming water, seriously polluting the water quality and affecting the healthy growth of shrimp. At the same time, it is difficult to concentrate the residual bait and feces to the sewage outlet only by drainage, and there is a problem of incomplete sewage discharge. Utility Model Content

[0025] The utility model is described in detail below in conjunction with the accompanying drawings.

[0026] See also Figure 1This embodiment provides a sewage discharge device for shrimp farming, which is installed on a shrimp farming pond. The sewage discharge device includes a sewage suction pump 1 immersed below the farming liquid level of the shrimp farming pond, a filter screen 2 covered on the sewage suction pump 1, a support frame 3 for carrying the sewage suction pump 1, two groups of turntables 4 horizontally arranged at corresponding positions on both sides of the sewage suction pump 1, three groups of cleaning arms 5 fixedly installed on the corresponding turntables 4, a rotary drive structure acting on the turntable 4, a water quality sensor 12 fixedly installed on the sewage suction pump 1, and a controller installed on the support frame 3.

[0027] In this embodiment, the sewage suction pump 1 is described by taking a submersible sewage suction pump of model 150WQ200-30 as an example. The controller is located above the aquaculture liquid surface, and wires are fixedly connected between the controller and the sewage suction pump 1, and between the controller and the water quality sensor 12. In this embodiment, the water quality sensor 12 is set to detect the water quality parameters of the aquaculture water body in the shrimp aquaculture pond (the water quality parameters include but are not limited to ammonia nitrogen concentration, nitrite nitrogen concentration, etc.), and the controller receives the signal of the water quality sensor 12. When the detected water quality parameter exceeds the preset value, the sewage suction pump 1 is started to perform the sewage discharge function.

[0028] The filter screen 2 is coated and fixed on the outside of the sewage suction pump 1, and the opening of the filter screen 2 is tightened. In this embodiment, the sewage suction pump 1 is operated to discharge the dirt (such as leftover bait and feces) in the shrimp breeding pond to the outside of the breeding pond through the sewage discharge pipe installed thereon. During the sewage discharge process, the shrimp is intercepted based on the filter screen 2, thereby preventing the shrimp from entering the sewage suction pump 1 and being discharged out of the pond.

[0029] The rotary drive structure includes a rotary motor 7 fixedly mounted on the support frame 3 , a driving shaft 8 and a driven rod 9 vertically rotating and penetrating the support frame 3 , two sets of gears 10 , and a crawler belt 11 meshingly mounted between the two sets of gears 10 .

[0030] The driving shaft 8 and the driven rod 9 are arranged horizontally, and the driving shaft 8 is fixedly connected to the output end of the rotating motor 7. The driving shaft 8 is vertically fixedly connected to the center of one set of turntables 4, and the driven rod 9 is vertically fixedly connected to the center of the remaining set of turntables 4. One set of gears 10 is fixedly sleeved on the driving shaft 8, and the remaining set of gears 10 is fixedly sleeved on the driven rod 9, and the gears 10 are located below the support frame 3. Based on the transmission effect of the gears 10 and the crawler 11, the synchronous rotation of the two sets of turntables 4 is realized.

[0031] The working process of the rotary drive structure of this embodiment is as follows: the rotary motor 7 drives the driving shaft 8 to rotate. At this time, the driven rod 9 rotates under the meshing transmission action of the crawler 11 and the two sets of gears 10, thereby driving the two sets of turntables 4 to rotate synchronously.

[0032] The support frame 3 is installed at the top of the shrimp breeding pond. Based on the support frame 3, the sewage discharge device is set up in the shrimp breeding pond without the need to modify the breeding pond. The three groups of cleaning arms 5 are arranged equidistantly along the curved surface of the corresponding turntable 4, and a brush 6 is fixedly installed at the arm head of the cleaning arm 5 facing away from the turntable 4. In this embodiment, when the turntable 4 rotates, the cleaning arm 5 rotates accordingly, driving the water flow to promote the sewage to flow to the sewage suction pump 1, while cooperating with the brush 6 to synchronously clean the dirt deposited around the sewage suction pump 1. The brush 6 plays the role of cleaning the filter 2, has a cleaning function to avoid blockage, and ensures the normal discharge of sewage. No manual cleaning is required, saving labor.

[0033] In summary, the sewage discharge device of this embodiment has the following advantages: simple operation, easy use, can be directly placed in the shrimp breeding pond for use, can quickly and efficiently complete the breeding pond sewage discharge while minimizing the transformation of the breeding pond, and can prevent the blockage of the sewage discharge equipment, without the need for manpower to clean the blockage, thereby reducing labor input.
