Description

Technical Field

[0001] The invention relates to the technical field of sanitation vehicles, and in particular to an unmanned sanitation vehicle which is convenient for cleaning vertical areas. Background Art

[0002] With the continuous research and development and production of sanitation equipment, more and more automated and intelligent sanitation equipment have been developed and put into urban road sanitation operations. Self-driving road sweepers are one of the more typical new sanitation equipment products.

[0003] At present, most of the unmanned sanitation vehicles on the market have two cleaning devices installed at the front end of the vehicle body. The vehicle body drives the cleaning devices to move continuously on the road surface to achieve the purpose of cleaning the road surface and beautify the city. However, some walls close to the roadside in the city will also be covered with a lot of dust and dirt, while most traditional unmanned sanitation vehicles can only clean the road surface, and the dirt on the vertical walls still needs to be cleaned manually by workers; for this reason, we provide an unmanned sanitation vehicle that is easy to clean in vertical areas to solve the above problems. Summary of the invention

[0004] Based on this, the purpose of the present invention is to provide an unmanned sanitation vehicle that is convenient for cleaning vertical areas, so as to solve the technical problems in the above-mentioned background technology.

A water suction pipe and a water delivery pipe are respectively connected to the piston box, and a nozzle is installed on one side of the water delivery pipe.

[0006] Furthermore, two sets of heating plates are provided at the lower interior of the water tank.

[0007] By adopting the above technical solution, the heating plate can heat the cleaning water in the water tank, and the warm water can soften the stains on the wall, thereby making the stains cleaned more thoroughly and improving the cleaning effect.

[0008] Furthermore, a battery is provided on one side of the base, a control console is provided on one side of the inner top of the water tank, and the heating plate, the battery, the first motor and the second motor are all electrically connected to the control console.

[0009] By adopting the above technical solution, the battery can power the heating plate, the first motor and the second motor, and the control console can control the heating plate, the first motor and the second motor.

[0010] Furthermore, an observation window is provided on one side of the water tank, and a water filling port is provided on the top of the water tank.

[0011] By adopting the above technical solution, the staff can check the water remaining in the water tank at any time through the observation window. When the water level is insufficient, the staff can add cleaning water to the water tank through the water filling port.

[0012] Furthermore, the outer surface and the back of the mounting seat are in contact with the mounting frame, and the mounting seat and the mounting frame are slidably matched.

[0013] By adopting the above technical solution, the mounting frame can limit the mounting seat, so that the mounting seat can only move vertically but cannot rotate.

[0022] Furthermore, the diameter of the driving wheel is much smaller than the diameter of the driven wheel.

[0023] By adopting the above technical solution, the active wheel with a smaller diameter drives the driven wheel with a larger diameter to rotate, so that the speed of the driven wheel can be slow, so that it can move slowly during linear motion, thereby ensuring the cleaning effect of each area.

[0024] In summary, the present invention mainly has the following beneficial effects:

[0025] 1. The present invention is provided with a first motor, an adjusting shaft, a second motor, a driving shaft, a fan gear, a gear rack, a piston box, a piston plate, a piston rod, a water pumping pipe, a water delivery pipe, a fixing rod, a screw rod, a threaded sleeve, a driving wheel, a driven wheel and a brush plate. When it is necessary to clean the wall, the first motor rotates to make the adjusting shaft drive the mounting frame to flip, so that the mounting frame is in a vertical state, and then the brush plate is made to fit the wall surface. Then the second motor is started, and the second motor rotates to rotate the driving shaft, and the driving shaft rotates to rotate the fan gear. The rotation of the fan gear can drive the gear rack to reciprocate, and the reciprocating swing of the gear rack can drive the brush plate to reciprocate at high frequency through the fixing rod, so that the brush plate can brush away the stains on the wall surface. , and when the gear rack swings back and forth, the piston rod drives the piston plate to do piston movement in the piston box, the water pumping pipe draws the water inside the water tank into the piston box, and the water delivery pipe sprays the water to the wall through the nozzle, so that the stains on the wall can be sprayed. At the same time, the driving shaft rotates the active wheel, and the active wheel rotates through the transmission belt to drive the active wheel to rotate. The active wheel rotates to rotate the threaded sleeve, and the threaded sleeve cooperates with the screw rod to drive the mounting seat to do linear movement, so that the mounting box can move vertically, and then the brush plate can move vertically on the wall, and then the brush plate can be fully cleaned from top to bottom, which effectively reduces the labor intensity of workers and ensures the cleaning efficiency of the wall;

[0026] 2. The present invention is provided with a limit groove, a limit rod, a movable rod mounting plate, a force plate, an eccentric wheel, a rotating shaft and a spring. When the bristles on the brush plate need to be replaced after being worn, the staff rotates the rotating shaft. The rotation of the rotating shaft causes the eccentric wheel to rotate. The rotation of the eccentric wheel can squeeze the force plate, so that the movable rod overcomes the elasticity of the spring and moves, thereby causing the limit rod to disengage from the limit groove. At this time, the staff can remove the brush plate from the mounting plate, thereby achieving the purpose of replacing the brush plate. By replacing the brush plate at any time, the cleaning effect is guaranteed, and the operation is simple and convenient. BRIEF DESCRIPTION OF THE DRAWINGS
