[0023] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0024] A blade-shaped rotary sweeping-type pool bottom drainer according to an embodiment of the present invention is as follows: Figure 1-Figure 6 As shown, it includes: a sewage discharge shaft pipe 2 connected to the bottom sewage outlet 11 of the culture pond 1, a plurality of through holes 21 for sewage to enter the bottom sewage outlet 11 are opened in the axial direction of the sewage discharge shaft pipe 2, a sweeping mechanism for sweeping the bottom sewage of the culture pond 1 is sleeved on the sewage discharge shaft pipe 2, the sweeping mechanism includes an impeller assembly sleeved on the sewage discharge shaft pipe 2, a blade assembly for sweeping the bottom sewage of the culture pond 1 is connected to the impeller assembly, the impeller assembly drives the blade assembly to sweep the bottom sewage of the culture pond 1, and the scraped sewage enters the bottom sewage outlet 11 from the through hole 21 for discharge; the bottom sewage outlet 11 is connected to the sewage discharge tank 112 through a sewage discharge pipe 111.

[0025] Furthermore, a water outlet hole 22 is provided on the sewage shaft pipe 2, which cooperates with the water inlet end 12 of the breeding pond 1. The water inlet end 12 is connected to the water pump 4 through a connecting pipe 3, and the connecting pipe 3 is passed through the sewage shaft pipe 2; the water outlet hole 22 cooperates with the impeller assembly; the water pump 4 is located in the clean water tank or the sewage tank.

[0026] Furthermore, in order to increase the power exerted by the medium flowing out of the water outlet 22 on the impeller assembly, an outer sleeve 5 is connected to the impeller assembly, and the outer sleeve 5 covers the sewage shaft pipe 2 inside, and a cavity for increasing power is formed between the outer sleeve 5 and the sewage shaft pipe 2.

[0027] Specifically, the impeller assembly includes an upper connecting plate 6 and a lower connecting plate 7 arranged at intervals, and a baffle 8 arranged at intervals is connected between the upper connecting plate 6 and the lower connecting plate 7. The upper connecting plate 6, the lower connecting plate 7 and the baffle 8 form an integral body, and the upper connecting plate 6 and the lower connecting plate 7 are both sleeved on the sewage discharge shaft pipe 2; a power outlet of the medium is formed between two adjacent baffles 8, and the baffle 8 forms a certain angle with the horizontal direction to facilitate maximizing the power of the medium.

[0028] Furthermore, in order to facilitate the connection between the upper connecting plate 6 and the sewage discharge shaft pipe 2 , a short pipe 9 matching with the sewage discharge shaft pipe 2 is connected to the upper connecting plate 6 .
