The lower end face of the transfer channel is provided with a transfer port opposite to the transfer bin, and the upper end face of the transfer channel is provided with a feed port adapted to the grabbing device. The feed port and the transfer port are arranged opposite to each other, and a push-pull plate is slidably connected to the transfer port, and the push plate is slidably connected to the push-pull plate. The length of the push-pull plate is equal to the distance from the inner wall of the left end of the transfer bin to the right end of the garbage bin. A push plate is slidably connected in the transfer channel, and the push plate is supported on the push-pull plate. The push plate is connected to a reel through a wire rope, and the reel is located above the transfer channel and rotates with the vehicle body.

[0006] The present invention provides transfer and power by setting up a vehicle body, and grabs garbage and sludge by setting up a grabbing device. The filter plate filters the garbage and sludge, and removes moisture through the extrusion and cooperation of the filter plate and the push-pull plate. The push-pull plate moves, and the filter plate pushes the garbage and materials into the transfer channel. The filter plate and the push-pull plate stop moving and serve as supports for the transfer channel to participate in subsequent operations. The push plate operates to push the garbage and sludge into the garbage bin for storage. The garbage bin is detachable. When one garbage bin is full, another garbage bin can be replaced to facilitate continuous operation.

[0007] As an optimization, the grabbing device includes a support turntable rotatably connected to the vehicle body. This turntable is connected to a connecting rod, to which a telescopic rod is fixed. The lower end of the connecting rod is connected to a bucket cover and bucket, with the bucket cover and bucket positioned opposite each other. An infrared camera is also mounted on the connecting rod. This optimized solution allows workers to operate the system from the front of the vehicle, allowing them to clean garbage and sludge from sewage wells.

[0008] As an optimization, the transfer bin includes a base and walls. The base is fixed to the vehicle body, while the walls extend vertically and are fixed to the base. Two platforms are fixed to the base, and the oil cylinder is fixed to the platforms. A drainage outlet is provided on the base. This optimized solution supports and restricts the garbage and sludge, utilizing gravity to facilitate the removal of moisture brought up during the garbage and sludge retrieval process.

[0009] As an optimization, the vehicle body is equipped with a sliding plate motor, which is connected to a gear. The sliding plate is equipped with several racks, which are respectively fixed to the front and rear ends of the lower end surface of the sliding plate. The sliding plate and the sliding plate motor are connected by a gear transmission. The sliding plate is equipped with a pressure sensor, which is electrically connected to the sliding plate motor and the oil cylinder. This optimized configuration can complete the sliding and pulling process of the sliding plate automatically. When the pressure sensor senses sufficient pressure, the sliding plate motor is activated, automatically completing the opening of the sliding plate.

[0010] As an optimization, a scraper is provided on the inner wall of the left end of the transfer bin, and the scraper extends up and down to the lower end surface of the push-pull plate. The setting of this optimization solution can scrape off the silt on the push-pull plate when the push-pull plate is opened.

The vertical plates extend vertically, with adjacent vertical plates fixedly connected to form a rectangular channel. The top plate is fixed to the upper end surfaces of the vertical plates, and the feed port is located on the top plate. This optimization solution facilitates the transfer of materials in the transfer channel to the waste bin.

[0013] As an optimization, a feed inlet partition door is provided at the feed inlet. A partition door motor and an infrared sensor are mounted on the top plate. The infrared sensor is electrically connected to the automatic door motor, which is in turn transmission-connected to the feed inlet partition door. This optimization solution allows the feed inlet partition door to automatically open when the infrared sensor senses the grabbing device.

[0014] This solution also provides a cleaning method using the municipal sewage well cleaning device, including the following aspects:

[0015] A. Observe through the infrared camera and operate the grabbing device to dig out the sludge and garbage. After digging, the grabbing device rotates to the top of the transfer device. The infrared sensor senses the grabbing device, the partition door motor rotates, the feed inlet partition door opens, the grabbing device opens, and the garbage and sludge fall into the transfer bin;

[0016] B. Press the transfer device button, the cylinder extends, pushing the filter plate upward, the filter plate squeezes the garbage and silt, and the water flows back to the sewage well through the drain port. When the pressure sensor reaches the predetermined threshold, the cylinder stops extending and drives the filter plate to move down 2-3 cm. Then the push-pull plate motor drives the push-pull plate to the left through the gear. When the left end face of the push-pull plate contacts the vehicle body, the push-pull plate motor stops rotating, the cylinder extends again, the filter plate moves upward, and the cylinder reaches its maximum stroke. At this time, the filter plate is flush with the push-pull plate, and the garbage and silt are transferred to the transfer channel. When the cylinder reaches its maximum stroke, the cylinder stops operating, and the drum motor drives the drum to rotate clockwise, pulling the wire rope through the drum, driving the push plate to move left, pushing the silt and garbage into the garbage bin;

[0017] C. The drum motor reverses and the drum rotates counterclockwise. The wire rope is pulled by the drum, driving the push plate to move right to the starting position. The oil cylinder contracts, driving the filter plate to move forward to the initial position. The push-pull plate motor drives the push-pull plate to move right through the gear and return to the initial position.

[0018] The beneficial effects of the present invention are: the present invention can replace manual cleaning, and workers only need to sit in the vehicle to complete the cleaning of the sewage well, thereby improving the workers' working environment. The cleaned sludge and garbage can be directly filtered and transferred to prevent the sludge and garbage from falling back into the sewage well and affecting the cleaning progress. The cleaned garbage and sludge are stored in the garbage bin, which does not affect the city appearance, and the cleaning of other sewage wells can continue. When a garbage bin is full, the garbage bin can be replaced and the full garbage bin can be stored on the vehicle body. When all operations are completed, the garbage and sludge can be subjected to subsequent operations. BRIEF DESCRIPTION OF THE DRAWINGS
