DETAILED DESCRIPTION

[0017] like Figure 1-5 As shown, a ground high-pressure flushing device includes an equipment carrier 1, which is an electric tricycle. A box 2 is provided on the equipment carrier 1, and an opening and closing door is provided on the back of the box 2. A high-pressure water supply device is provided in the box 2. A liftable high-pressure flushing mechanism 3 is provided at the bottom end of the rear of the equipment carrier 1. When flushing, the high-pressure flushing mechanism 3 can be lowered to the ground, and the high-pressure water supply device and the high-pressure flushing mechanism 3 are turned on. When the equipment carrier 1 moves, the high-pressure flushing mechanism 3 at its rear end is used to flush the passing ground. At the same time, when not in use, the high-pressure flushing mechanism 3 can be raised without affecting the normal use of the equipment carrier 1.

[0018] The high-pressure flushing mechanism 3 includes a rotating frame 301 whose front end is hinged to the bottom end of the rear end of the equipment carrier 1 through an articulated seat 302. There are two articulated seats 302, which are respectively located on both sides of the front end of the rotating frame 301, so that the rotating frame 301 rotates around the articulated seat 302, thereby achieving a lifting effect at the rear end. A number of lifting and telescopic cylinders 303 are arranged between the rotating frame 301 and the equipment carrier 1. In this embodiment, there are two lifting and telescopic cylinders 303, and the two ends of the lifting and telescopic cylinders 303 are respectively hinged to the rotating frame 301 and the equipment carrier 1, so as to utilize the extension and retraction of the two lifting and telescopic cylinders 303 to achieve the effect of controlling the rotation of the rotating frame 301.

[0019] Two symmetrical limiting mechanisms 304 are also provided at the bottom of the equipment carrier 1. The two limiting mechanisms 304 are respectively located on both sides of the rear end of the rotating frame 301. The limiting mechanisms 304 can be used to support the rear end of the rotating frame 301 when it is retracted to prevent the lifting and telescopic cylinder 303 from being subjected to excessive force during the movement of the equipment carrier 1.

[0020] The rear end of the rotating frame 301 is hinged with a high-pressure water pipe 306 through an elastic hinge assembly 305. The width of the high-pressure water pipe 306 is adapted to the width of the equipment carrier 1. A plurality of high-pressure nozzles 307 are arranged horizontally on the outside of the high-pressure water pipe 306. In this embodiment, the number of the high-pressure nozzles 307 is seven, and when the high-pressure nozzles 307 fall above the ground to form an angle with the ground, a plurality of rollers 308 that can fit with the ground are arranged at the bottom of the high-pressure water pipe 306. In this embodiment, the number of the rollers 308 is two. The water inlet end of 6 is connected to the high-pressure water supply equipment through a high-pressure hose 309, and the high-pressure hose 309 is used to achieve the water supply effect. When the tail end of the rotating frame 301 rotates to the ground, the roller 308 fits with the ground, thereby effectively fixing the distance between the high-pressure nozzle 307 and the ground, so that the high-pressure nozzle 307 can continue to maintain this distance to perform high-pressure cleaning on the ground. At the same time, when the ground is uneven, the elastic hinge component 305 can be used to make the high-pressure water pipe 306 and the roller 308 close to the ground, and adaptively adjust with the unevenness of the ground.

[0021] It should be noted that the high-pressure water supply equipment in this embodiment is composed of a water tank, a high-pressure pump, a motor, a safety valve, a pressure regulating valve and a control system. Since it is a commonly used technical means in this field, it will not be described in detail here.

[0022] In the preferred embodiment, the limiting mechanism 304 includes a lifting plate 3041 fixedly mounted on the top end of the rear portion of the equipment carrier 1, and a limiting telescopic cylinder 3042 is fixedly mounted on the lifting plate 3041. The output end of the limiting telescopic cylinder 3042 can be telescopically extended through the lifting plate 3041, and a C-shaped limiting block 3043 is provided. The groove on the C-shaped limiting block 3043 is adapted to the rotating frame 301, and the C-shaped limiting block 3043 is extended and retracted by the extension and retraction of the output end of the limiting telescopic cylinder 3042. Therefore, when the rotating frame 301 is in the retracted state, the limiting telescopic cylinder 3042 is used to push the C-shaped limiting block 3043 to the side of the rotating frame 301, and the rotating frame 301 is embedded in the groove of the C-shaped limiting block 3043, thereby achieving the limiting effect. When it needs to be unfolded and used, the limiting telescopic cylinder 3042 is used to retract the C-shaped limiting block 3043.

[0023] In the preferred embodiment, the elastic hinge assembly 305 includes an articulated U-shaped seat 3051 disposed at the bottom of the rotating frame 301, and an articulated block 3052 whose end is connected to the high-pressure water pipe 306 is disposed in the articulated U-shaped seat 3051. The articulated block 3052 is rotatably connected to the articulated U-shaped seat 3051 through articulated shafts 3053 disposed on both sides. The outside of the articulated shaft 3053 is sleeved with a reset torsion spring 3055. The side of the articulated block 3052 is connected to the side of the articulated U-shaped seat 3051. Torsion spring limit blocks 3054 are provided on the inner wall, and the two ends of the reset torsion spring 3055 are respectively hooked with the two torsion spring limit blocks 3054. Under the action of the reset torsion spring 3055, the roller 308 can be kept in contact with the ground, thereby determining the distance between the high-pressure nozzle 307 and the ground. At the same time, when the ground is uneven, the height of the roller 308 and the high-pressure nozzle 307 can be adaptively adjusted by compressing the reset torsion spring 3055, so that the roller 308 is always in contact with the ground.

[0024] In the preferred embodiment, rotation limit grooves 3056 are provided on the inner wall surfaces of the hinge holes on both side walls of the hinged U-shaped seat 3051, and a rotation limit block 3057 slidably connected to the rotation limit groove 3056 is provided on the outside of the hinge shaft 3053 rotatably arranged in the hinge hole. The rotation range of the high-pressure water pipe 306 can be limited by sliding the rotation limit block 3057 and the rotation limit groove 3056.

[0025] In the preferred embodiment, an elastic pull rope 310 is also fixedly provided at the bottom of the equipment carrier 1, and the other end of the elastic pull rope 310 is connected to the high-pressure hose 309, wherein the high-pressure hose 309 located between the elastic pull rope 310 and the bottom of the equipment carrier 1 has a sufficient section reserved for facilitating the rotation and lifting of the high-pressure water pipe 306, and the high-pressure hose 309 located between the elastic pull rope 310 and the high-pressure water pipe 306 is a tensioning section. The elastic pull rope 310 can be used to pull the high-pressure hose 309 back when the high-pressure flushing mechanism 3 is retracted.
