[0026] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0027] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other.

[0028] In the present application, unless otherwise specified, directional words such as "up, down, top, bottom" are usually used with reference to the directions shown in the drawings or are used to describe the relative positional relationships of components in the vertical, perpendicular or gravity direction.

[0029] The present application will be described in detail below with reference to the accompanying drawings and in combination with implementation modes.

[0030] The sewage temporary storage mechanism provided in this embodiment includes: a sewage box 1; a filter screen 4, the filter screen 4 covers the open end of the sewage box 1; and an electrode sheet 3, there are two electrode sheets 3, the two electrode sheets 3 are respectively located at the two ends of the length direction of the sewage box 1, and the electrode sheets 3 extend into the sewage box 1. A bracket 2 is provided above the sewage box 1, the bracket 2 is installed on the sewage box 1, and the electrode sheets 3 are installed at both ends of the bracket 2.

[0031] The sewage temporary storage mechanism provided in this embodiment has two electrode sheets extending into the two sides of the sewage box respectively, which can not only avoid false detection when sewage enters the sewage box due to the two electrode sheets being relatively close; it can also avoid openings on the filter screen to avoid the electrode sheets, causing large particles of dirt to fall into the sewage box, thereby ensuring the filtering function of the filter screen.

[0032] The sewage box 1 comprises a box body 11 and a wiper strip 12 . The box body 11 is in a long strip shape and has an opening at the top. The wiper strip 12 is arranged on one side of the box body 11 in the width direction and extends along the length direction of the box body 11 .

[0033] There are two ways to set the wiper strip. The first way is to install the wiper strip on the box body and form it as one piece with the box body. The second way is to install the wiper strip on the inner wall of the cavity that holds the roller at the base. Generally, a drainage plate is also set on the box body. The drainage plate is used to guide the sewage squeezed out by the wiper strip into the box body. The first way is equivalent to integrating the wiper strip and the drainage plate together.

[0034] The side walls 15 at both ends of the sewage box 1 in the length direction are recessed outward to form a storage space for accommodating the electrode sheet 3. Water guide plates 14 are respectively provided on both sides of the wiper strip 12, and the water guide plates 14 extend obliquely along the width direction of the sewage box 1. The distance between the ends of the two water guide plates 14 close to the box body 11 is smaller than the distance between the ends away from the box body 11. The storage space is located outside the water guide plates 14, that is, the electrode sheet 3 is located between the end of the water guide plates 14 close to the box body 11 and the side wall 15 of the sewage box 1.

[0035] The sewage temporary storage mechanism provided in this embodiment has water guide plates extending obliquely along the width direction on both sides of the wiper strip. On the one hand, the wiper strip can squeeze the parts at both ends of the roller to fully squeeze out the sewage in the roller and discharge it into the sewage box; on the other hand, it plays a role in shielding the electrode sheet to prevent the sewage from contacting the electrode sheet during the process of flowing into the box body, causing false detection of the electrode sheet, and also makes room for the installation of the electrode sheet.

[0036] Baffles 13 are provided on both sides of the sewage box 1 in the length direction, the baffles 13 are located inside the sewage box 1, the electrode sheet 3 is located between the baffles 13 and the side walls 15 in the length direction of the sewage box 1, a water gap is provided between the baffles 13 and the bottom of the sewage box 1, or the baffles 13 themselves are provided with a water gap.

[0037] The sewage temporary storage mechanism provided in this embodiment prevents the sewage in the sewage box from surging during the movement of the cleaning device by setting baffles on both sides of the box body, which causes the electrode sheet to be unable to accurately detect the water level in the sewage box. The water gap between the baffle or the baffle and the bottom of the box body can ensure that the sewage enters the accommodation space of the electrode sheet, so that the electrode sheet can normally detect the sewage water level.

[0038] The electrode sheet 3 comprises a mounting portion 31 , a power receiving portion 33 and a detection portion 32 . The mounting portion 31 is arranged on the bracket 2 , the detection portion 32 extends into the sewage box 1 , and the power receiving portion 33 is electrically connected to the electric control board.

[0039] The detection part 32 is in the shape of a vertical plate and extends along the height and width of the sewage box 1. Compared with the way that the electrode sheet extends along the width of the sewage box, the electrode sheet in this embodiment extends along the width of the sewage box to free up installation space for the easily detachable part 5.

[0040] The mounting portion 31 is in the shape of a flat plate and is arranged along a horizontal plane, that is, along the horizontal plane where the length direction and width direction of the sewage box are located. Screw holes are arranged on the mounting portion 31, and the mounting portion 31 is fixed to the bracket by screws passing through the screw holes; the power receiving portion 33 is in the shape of a vertical plate and extends along the height and length direction of the sewage box. The power receiving portion and the detection portion are arranged at an angle, for example, at a right angle.

[0041] The rolling and dragging device provided in this embodiment includes a base 6; a rolling and dragging device 71, which is rotatably mounted at the bottom of the base 6; and the above-mentioned sewage temporary storage mechanism, which is detachably connected to the base. A detachable part 5 is provided on the bracket 2, and the bracket 2 is detachably connected to the base 6 through the detachable part 5. A motor 72 is provided on the upper part of the base 6, and a gear box 72 is provided on the side of the base 6. A transmission gear is provided in the gear box, and the motor 72 drives the rolling and dragging device 71 to rotate through the gear box 72.

[0042] The easily detachable part 5 is mounted on the bracket 2, and a limiting groove 61 is provided at the rear of the base 6. The easily detachable part 5 extends into the limiting groove 61. When the easily detachable part 5 rotates clockwise, the easily detachable part 5 is clamped into the limiting groove 61. When the easily detachable part 5 rotates counterclockwise, the easily detachable part 5 can be pulled out of the limiting groove 61, and then the entire sewage temporary storage mechanism can be removed from the base. The above-mentioned easily detachable part 5 is a rotating easily detachable part, and of course the easily detachable part 5 can also be a press-type clamping part.

[0043] In the rolling and dragging device provided in this embodiment, the bracket 2 serves as a connecting component between the sewage box 1 and the base 6. By detachably connecting the bracket 2 and the base 6, after the electrode sheet 3 has worked for a period of time, the sewage temporary storage mechanism can be removed from the base as a whole to clean the dirt on the surface of the electrode sheet, so as to maintain the ability of the electrode sheet to accurately detect the sewage water level.

[0044] A power supply component 8 is provided at the rear of the base 6. When the sewage temporary storage mechanism is installed on the base 6, the power supply component 8 and the power receiving part 33 are elastically contacted and connected. The power supply component 8 includes a power supply electrode sheet and an elastic component installed on the power supply electrode sheet, and the elastic component is electrically contacted with the power receiving part 33.

[0045] A wiring groove is provided on the base 6, and a signal line electrically connected to the power supply is provided in the wiring groove. The signal line transmits the signal of the two electrode sheets being turned on to the electric control board. The conduction of the two electrode sheets 3 indicates that the sewage in the sewage box has reached a preset water level.

[0046] The cleaning equipment provided in this embodiment includes a chassis; a sewage pumping device, which includes a sewage tank, a sewage pump and a sewage pumping pipe, and the sewage pumping pipe connects the sewage tank and the sewage box 1; the above-mentioned rolling and dragging device; and an electric control board, which is electrically connected to the electrode sheet 3 and the sewage pump. When receiving a signal from the electrode sheet 3 that the sewage in the sewage box has reached a preset water level, the electric control board sends a command to the sewage pump to pump the sewage in the sewage box into the sewage tank.

[0047] The cleaning equipment also includes a clean water supply device, which includes a clean water tank, a water spray box, a clean water pump and a clean water pipe. The water spray box sprays clean water onto the roller, the clean water pipe connects the clean water tank and the clean water box, and the clean water pump is arranged on the clean water pipe to pump the clean water in the clean water tank to the water spray box.
