The range of the mounting plate 223 being turned upside down is limited by the arc-shaped guide rail 23. In the present embodiment, the arc of the arc rail 23 is 90 degrees. When the mounting plate 223 slides to the lowest point of the arc-shaped guide rail 23, the rocking bar 221 is parallel to the ground, and when the mounting plate 223 slides to the highest point of the arc-shaped guide rail 23, the rocking bar 221 is perpendicular to the ground.

As shown in fig. 2, fig. 3 and fig. 10, the turnover mechanism 2 further includes a driving push rod 24 with a fixed end hinged to the chassis 3, a movable end of the driving push rod 24 is hinged to the bottom of the mounting plate 223, the driving push rod 24 is parallel to the telescopic rods 224, the two telescopic rods 224 are symmetrically arranged at two sides of the driving push rod 24, the driving push rod 24 pushes the mounting plate 223 to drive the telescopic rods 224 to synchronously extend and retract, so that the washing mechanism 1 is turned over up and down. The independent push-pull mounting plate 223 is pushed through driving, and the telescopic rod 224 is driven to stretch synchronously, so that the washing mechanism 1 is turned over up and down, and the washing range of the washing mechanism 1 is further enlarged. Since the height of the mounting plate 223 changes when the driving shaft 212 drives the mounting plate 223 to turn up and down, and the mounting plate 223 is always perpendicular to the ground, the spraying distance of the front corner nozzle 112 changes and the spraying angle of the front corner nozzle 112 does not change. The push rod 24 is driven to push the mounting plate 223 to adjust the spraying angles of the front corner nozzle 112, the side corner nozzle 115 and the three-dimensional nozzle 127, so that the washing range of the washing mechanism 1 is enlarged, and on the other hand, the structural stability of the mounting plate 223 is improved, so that the washing mechanism 1 is more stable in operation.

As shown in fig. 10, the mud guard 113 is provided with a distance sensor connected to the control system 4 to monitor an obstacle on the ground in front in real time. In this embodiment, the control system 4 employs a PLC to automatically control the turnover mechanism 2 and the lifting device 116 to achieve the obstacle avoidance function of the flushing mechanism 1, and the PLC control system 4 includes an input unit, a detection unit, and an output unit. The input unit is that when the lifting push rod 1161 in the flushing mechanism 1 extends out to enable the front corner nozzle 112 on the transverse spray pipe 111 to be tightly attached to the ground, the PLC system with the obstacle avoidance function of the control system 4 starts to operate, the distance sensor arranged on the mud covering plate 113 serves as a signal detection unit, when the distance sensor detects that an obstacle exists in front of the PLC system, a signal is fed back to the execution unit, and the execution unit enables the driving push rod 24 and the driven gear 211 to act to enable the flushing mechanism 1 to be lifted upwards, so that obstacle avoidance is achieved; after the obstacle is crossed, the distance sensor feeds back a signal to the execution unit again, so that the driving push rod 24 and the driven gear 211 act to return to the initial positions, and the automatic obstacle avoidance function is achieved. When the flushing vehicle goes on and off the logistics vehicle and passes through a steep slope, the flushing mechanism 1 can be lifted upwards by controlling the actions of the driving push rod 24 and the driven gear 211, so that the flushing mechanism 1 is turned over to the position above the chassis 3, and the flushing mechanism 1 is prevented from being damaged.

As shown in fig. 1, the flushing vehicle of the present embodiment further includes an angle spraying device 6 installed below the chassis 3 and located between the steering axle and the driving axle. The flushing mechanism 1 is used for flushing garbage in operation blind areas such as sidewalks and flower bed corners, and flushing the garbage to the flushing range of the corner spraying device 6. The waterway system 5 comprises a motor, a high-pressure water pump, a water valve assembly, a waterway assembly and a water tank. The water tank is installed at the rear part of the chassis 3, is positioned above the drive axle and is fixed by a strap for storing water for flushing operation. The motor is directly connected with the high-pressure water pump and is fixed in front of the washing vehicle, the motor drives the high-pressure water pump to provide high-pressure water for the washing mechanism 1 and the angle spraying device 6, and meanwhile, the washing vehicle carries a reel and a handheld spray gun for manual operation so as to clean dirty oil-polluted road surfaces. The washing vehicle also comprises a cover assembly 7 fixed at the front, top and rear parts of the whole vehicle, and is used for keeping out rain and sun, insulating heat and sound, preventing water and oil pollution and protecting a water tank.

The flushing vehicle of the embodiment has a manual flushing mode and an intelligent flushing mode. Manual flushing mode: the side angle nozzle 115 is adjusted to a proper angle, garbage is flushed to the washing range of the angle spraying device 6, the washing strength can be selected according to the quantity of the garbage, and the side angle nozzle is mainly used for cleaning dead angles which are difficult to clean, such as vehicle bottoms, curb dead angle positions, flower bed corners and the like, can be cleaned without getting off, and is high in working efficiency. Intelligent flushing mode: after the vehicle is started, the working state of the side angle nozzle 115 is adjusted in time according to the moving speed of the washing vehicle, and the proper washing angle and washing intensity are adjusted, so that the vehicle speed of the washing vehicle is matched with the current working state.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
