[0002] After a period of use, the bottom of the aquaculture pond is prone to some dirt and bacteria. Therefore, the aquaculture pond needs to be cleaned regularly. The traditional treatment method is to manually enter the aquaculture pond with a handheld brush to clean the pond wall and bottom, which is not only time-consuming and labor-intensive, but also has high labor intensity and low cleaning efficiency.

[0003] To solve the above problems, the Chinese invention patent with the authorization announcement number CN104521871A discloses a bottom suction device for aquaculture ponds, including an electric brush, a base, a telescopic connecting rod, a water pump, a handle and a sewage pipe. The electric brush includes a brush head, a small motor and a connecting rod. The brush head and the small motor are connected by the connecting rod. The electric brush is arranged in the four corners of the base. The central position of the base is provided with a sewage suction port, which is connected to the sewage pipe, and the sewage pipe is connected to the water pump. A telescopic connecting rod is provided on the back of the base, and a hanging ring is provided on the telescopic connecting rod, and a handle is provided on the telescopic connecting rod. The brush head is a conical brush head. The hanging ring is a circular closed hanging ring.

[0004] Aquaculture farms usually have several breeding ponds of different sizes, and different types of aquatic products are usually placed in the breeding ponds. In the above patent, one water pump only drives one suction head to work. When one breeding pond is cleaned and the next breeding pond needs to be cleaned, the suction head carries debris and bacteria from the previous breeding pond. When cleaning the next breeding pond, these debris and bacteria are brought into the next breeding pond, which may cause cross-infection of bacteria in different breeding ponds, causing the fry in the breeding ponds to become sick or die.

DETAILED DESCRIPTION

[0018] The specific implementation of the present invention is described below with reference to the accompanying drawings. In order to fully understand the present invention, many details are described below, but for those skilled in the art, the present invention can be implemented without these details. For well-known components, methods and processes, they are not described in detail below.

[0019] An improved aquaculture pond sewage suction device, referring to Figure 1 , including a sewage collecting tank 10, a fan 20, a sewage main pipe 30 and a sewage suction unit 40. A sewage main pipe 30 is connected to a plurality of sewage suction units 40, and the sewage main pipe 30 is connected to the feed port of the sewage collecting tank 10 through the fan 20; the sewage main pipe 30 shown in the embodiment is connected to two sewage suction units 40, which can realize the cleaning of two breeding ponds at the same time, avoiding cross infection and improving work efficiency.

[0020] Reference Figure 1 The sewage suction unit 40 includes a sewage suction head 41, a universal coupling 42, a connecting pipe 43, a sewage suction branch pipe 44 and a telescopic rod 45. The top of the sewage suction head 41 is connected to one end of the connecting pipe 43 through the universal coupling 42. The universal coupling 42 is preferably a ball-jointed universal coupling. The other end of the connecting pipe 43 is connected to the sewage suction branch pipe 44. The top of the sewage suction branch pipe 44 is connected to the sewage main pipe 30.

[0021] Reference Figure 1 A connecting plate 46 is fixedly connected to the side of the connecting pipe 43, and the connecting plate 46 is hinged to one end of the telescopic rod 45. The sewage suction branch pipe 44 is a telescopic bellows. When the sewage suction head 41 is moved to a suitable position and angle, the universal coupling 42 and the telescopic rod 45 make the overall movement of the sewage suction head 41 more mobile and flexible.

[0022] Reference Figure 2 The suction head 41 includes a shell 411, a brush 412 and a roller 413. A suction port 414 is provided at the center of the bottom of the shell 411. A central through hole is provided at the center of the universal coupling 42. The suction port 414 is connected to the connecting pipe 43 through the universal coupling 42. The brush 412 is fixed to the bottom of the shell 411. At least part of the brush 412 extends out of the suction port 414. A roller 413 is provided at each end of the bottom of the shell 411.

[0023] When the breeding pool needs to be cleaned, the cleaning staff only needs to stand beside the breeding pool, without standing in the breeding pool, so as not to slip and get injured, and then adjust the telescopic rod 45 according to the position of the dirt in the breeding pool, so that the suction head 41 reaches a suitable position, and then use the brush 412 on the suction head 41 to scrub the dirt in the breeding pool, and a brush 412 is provided on both sides of the suction port 414, and a roller 413 is provided at each end of the bottom of the shell 411, so that the suction head 41 can slide in the breeding pool. The dirt in different aquaculture pools is sucked into the suction branch pipe 44 through the suction port 414 at the bottom of the suction head 41 under the negative pressure absorption effect generated by the fan 20, and the dirt is then gathered in the sewage main pipe 30 and enters the sewage collection tank 10.

[0024] Reference Figure 1 A regulating valve 50 is provided at the connection between the sewage suction branch pipe 44 and the sewage main pipe 30 in each sewage suction unit 40. When it is necessary to clean one or several breeding pools, the corresponding regulating valve 50 can be opened, and the other regulating valves 50 remain closed to ensure that the overall suction force of the sewage suction device remains at the maximum; after cleaning, the regulating valve 50 is closed in time to prevent dirt and bacteria in other breeding pools in the sewage main pipe 30 from mixing into the sewage suction unit 40.

[0025] The above is only a specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
