[0021] In this embodiment, it should be noted that the drainage pump body 4 placed in the cleaning box 1 is a drainage pump whose driving motor and the lower shell have been disassembled. The drainage pump body 4 is placed as a whole on the drain platform 104 fixedly connected to the bottom end of the cleaning box 1.

When the cleaning mechanism 6 sprays a high-speed water flow to flush the drainage pump body 4, the sewage flushing the lower shell 402 of the drainage pump body 4 and the water outlet 403 flows out from the drain hole 1042 at the bottom of the drain platform 104, and together with the sewage falling after flushing the upper part of the drainage pump body 4, it is gathered along the inclined groove 1031 to the bottom side of the cleaning box 1, and finally flows out of the cleaning box 1 from the outlet groove 1032.

[0024] Reference Figures 1 to 6 The top of the top plate 102 is fixedly connected with a driving block 201 symmetrically arranged along the center line, the top of the driving block 201 is fixedly connected with a guide rod 202, the top of the guide rod 202 is fixedly connected with a baffle 203, wherein the guide rods 202 symmetrically arranged at the top of the top plate 102 are movably connected to the sides of the sliding rods 204, the middle part of the sliding rod 204 is in a circular ring shape, and a driving motor 301 is fixedly connected inside, the bottom end of the driving motor 301 is fixedly connected to a shell 302, and a clamping assembly 303 is movably connected to the bottom of the side of the shell 302, and the clamping assembly 303 is in a ring array on the side of the shell 302, and the bottom ends of the four clamping assemblies 303 can fix the driving motor 2 401 when they move centripetally at the same time, and the driving block 201 controls the sliding rod 204 to move up and down along the two guide rods 202 to complete the lifting movement of the clamping mechanism 3.

[0025] Reference Figure 3 A screw rod 3011 extends from the bottom end of the driving motor 1 301, and a sliding sleeve 3031 is movably connected to the side of the screw rod 3011, and four fixing seats 1 3032 of a circular array are fixedly connected to the side of the sliding sleeve 3031. The fixing seat 1 3032 is movably connected to the fixing seat 2 3034 through a connecting rod 3033, and a clamping arm 3035 is fixedly connected to the bottom end of the fixing seat 2 3034. The clamping arm 3035 is movably connected to the shell 302 through a short rod 3036 on one side of the top, and a clamping pad 3037 is fixedly connected to the bottom end thereof. The shell 302 is provided with a vertical groove 3021 in the movable area of ​​the connecting rod 3033, and both ends of the short rod 3036 are fixedly connected to the inner wall of the vertical groove 3021.

[0026] The clamping assembly 303 includes a driving motor 1 301, a housing 302 and a clamping assembly 303, wherein the clamping assembly 303 further includes a sleeve 3031, a fixing seat 1 3032, a connecting rod 3033, a fixing seat 2 3034, a clamping arm 3035, a short rod 3036 and a clamping pad 3037. The driving motor 1 301 controls the lifting and lowering of the sleeve 3031 by controlling the rotation of the screw rod 3011. When the sleeve 3031 rises, one end of the connecting rod 3033 is driven to move upward, and the other end of the connecting rod 3033 is fixed to one end of the horizontal plane at the top of the clamping arm 3035 through the fixing seat 2 3034. The horizontal plane at the top of the clamping arm 3035 The other end is movably connected to the inner wall of the vertical groove 3021 opened in the outer shell 302 through the short rod 3036. Therefore, the upward movement of the connecting rod 3033 will cause the clamping arm 3035 to perform a diffusion movement with the short rod 3036 as the center of the circle. This action also prepares the clamping arm 3035 to clamp the driving motor 2 401, that is, the upper part of the drainage pump body 4. When the sliding sleeve 3031 descends, the connecting rod 3033 moves downward, which will cause the clamping arm 3035 to perform a centripetal contraction movement with the short rod 3036 as the center of the circle, so that the bottom end of the clamping arm 3035 clamps the side wall of the driving motor 2 401. The presence of the clamping pad 3037 makes the clamping action more stable and avoids slipping.

The telescopic rod 502 drives the wheel brush 503 to perform telescopic movement inside the water outlet 403 to brush the dirt attached to the inner wall of the water outlet 403 to ensure smooth water flow when the drainage pump is working.
