[0027] In this embodiment, the adjustment component includes a support rod 101, a baffle 102 is provided at one end of the support rod 101, a screw 103 is provided on the side of the baffle 102 away from the support rod 101, a mounting plate 104 is provided on the end of the screw 103 away from the baffle 102, and two hinge seats 105 are symmetrically provided on the side of the mounting plate 104 away from the screw 103, an adjustment rod 106 is installed on the hinge seat 105, a threaded sleeve 107 is installed on the screw 103, and a fixing ring 108 is provided on one side of the threaded sleeve 107, and the fixing ring 108 and the adjustment rod 106 are connected. A connecting rod 109 is arranged between the threaded sleeve 107, the threaded sleeve 107 is circular in shape, and the surface of the threaded sleeve 107 is provided with friction lines. The device is extended into the tank body through the support rod 101, and then the threaded sleeve 107 on one side of the baffle 102 is rotated, so that under the action of the screw 103, the threaded sleeve 107 drives one end of the connecting rod 109 to move along the screw 103 through the fixing ring 108, thereby pushing the adjusting rod 106 to rotate and open around the hinge seat 105 under the support of the mounting plate 104, so that the washing component is close to the circumference of the inner wall of the tank body, and finally the device is rotated through the support rod 101 to wash the inner wall of the tank body;

[0028] In this embodiment: the scrubbing assembly includes a connecting seat 201, a fixing plate 202 is arranged on the connecting seat 201, bristles 304 are installed on the fixing plate 202, a connecting plate 204 is arranged on one side of the fixing plate 202, a corner brush 205 is installed on the connecting plate 204, the corner brush 205 is in an inverted L shape, and the top surface is an arc surface, the adjusting rod 106 opens the upper and lower brush plates 203 through the connecting seat 201 and the fixing plate 202 and presses against the circumferential surface of the inner wall of the tank body, and presses the corner brush 205 against the connection between the bottom wall of the tank body and the circumference of the inner wall through the connecting plate 204;

[0029] In this embodiment: the telescopic component includes four brush rods 301, the four brush rods 301 are staggered up and down, and two adjacent brush rods are connected end to end, a slide groove 302 is opened on the front side of the brush rod 301, a limit block 303 is arranged in the slide groove 302, and bristles 304 are arranged on one side of the brush rod 301.

When rotating washing, the bristles 304 wash the bottom wall of the tank.

[0030] Working principle: The device is extended into the tank body through the support rod 101, and the bristles 304 and the corner brush 205 are close to the bottom wall of the tank body. Then, the threaded sleeve 107 on one side of the baffle 102 is rotated, so that under the action of the screw 103, the connecting rod 109 is driven by the fixing ring 108 to move along the screw 103, thereby pushing the adjusting rod 106 to rotate around the hinge seat 105 under the support of the mounting plate 104. The adjusting rod 106 then moves the upper and lower pieces through the connecting seat 201 and the fixing plate 202. The brush plate 203 opens and rests against the circumferential surface of the inner wall of the tank body. At the same time, the fixed plate 202 drives the four brush rods 301 to slide alternately along the slide groove 302 under the restriction of the limit block 303, so that the effective length of the bristles 304 is adjusted synchronously; finally, the device is rotated by the support rod 101, so that the brush plate 203 scrubs the circumference of the inner wall of the tank body, the bristles 304 scrub the bottom wall of the tank body, and the corner brush 205 scrubs the connection between the bottom wall of the tank body and the circumference of the inner wall under the support of the connecting plate 204.
