The frame body 1 The outer wall is provided with a water tank body 3, and the output end of the water tank body 3 is connected to a spray pipe 4 corresponding to the grille 5. In the device, the motor 2 can drive the auger 201 to rotate, and can pull the debris inside the grille 5, so that the debris enters the middle frame 102. The debris is squeezed inside the middle frame 102, and water can be transported to the spray pipe 4 through the water tank body 3. Then, the water outlet on the spray pipe 4 can derive a high-pressure water flow, and the squeezed and compressed debris is discharged through the discharge port on the upper frame 101;

[0028] The frame body 1 is provided with a cleaning assembly 6 which is located outside the grille 5 and rotates to clean the grille 5. The cleaning assembly 6 is provided with a push plate 602 corresponding to the water outlet of the spray pipe 4. When the device is in use, when the spray pipe 4 sprays high-pressure water, the high-pressure water flow is used to flush the grille 5. Further, the push plate 602 and the cleaning assembly 6 can be pushed to rotate to clean the grille 5. The water sprayed from the water outlet of the spray pipe 4 pushes the push plate 602 to rotate, that is, the rotation of the cleaning assembly 6 is realized. The surface of the grille 5 is cleaned by the rotating cleaning assembly 6, which can improve the service life of the device.

[0029] The rack body 1 is connected with a mounting arm 8 and an adjustable width mounting bracket 7. The mounting arm 8 is arranged close to the grille 5. During the installation of the device, the position of the mounting arm 8 can be fixed and limited first, and the mounting bracket 7 can be adjusted in width according to the width of the installation position. The mounting bracket 7 is installed and limited, so as to assist the device to be installed quickly. After the installation is completed, a stable support for the rack body 1 can be formed, and the operation is simple and convenient to use.

[0030] The second embodiment is different from the first embodiment in that:

[0031] The cleaning assembly 6 includes a baffle 601 that is slidably matched with the lower frame 103. The baffle 601 is located on the outer side of the grille 5 and corresponds to the grille 5. The horizontal direction is an arc-shaped cross-section. The surface of the baffle 601 facing the grille 5 is provided with a cleaning layer 603. The push plate 602 is arranged away from the grille 5. The push plate 602 is inclined. The surface of the push plate 602 facing the grille 5 is the negative surface. The water outlet on the spray pipe 4 faces the negative surface of the push plate 602. When the spray pipe 4 discharges water, the water flow can be used to push the push plate 602, and the push plate 602 can be pushed to rotate. The rotating baffle 601 and the cleaning layer 603 are used to clean the grille 5.

[0032] In the rotation installation of the baffle 601, a slide groove is provided on the outer wall of the lower frame 103, and also includes an annular frame 604 that rotatably cooperates with the slide groove on the lower frame 103. The baffle 601 is connected to the annular frame 604, and the sliding cooperation between the annular frame 604 and the slide groove is utilized to realize the rotation installation of the baffle 601. The annular frame 604 presents an annular surface corresponding to the annular groove on the lower frame 103, and a plurality of groups of rotating wheel groups 605 are provided on the surface of the annular surface. The rotating wheel groups 605 rotatably cooperate with the lower frame 103 to realize the rotation connection of the annular frame 604. Each group of rotating wheel groups 605 includes three rotating rollers. The outer walls of the rotating rollers arranged above and below are respectively matched with the upper wall and the lower wall gap of the slide groove to realize the guiding of the annular frame 604. Furthermore, the outer side of the annular frame 604 has a plurality of baffles 601 arranged at intervals to improve the cleaning effect of the grille 5.

[0033] The third embodiment is different from the first embodiment in that:

[0034] The mounting bracket 7 includes a threaded rod 703 and a rotating arm 701 that rotates with the middle frame 102. There are two rotating arms 701, which are respectively located on both sides of the middle frame 102. The high end of the rotating arm 701 is rotatably connected to a threaded seat 702. The two ends of the threaded rod 703 are provided with threaded sections with opposite rotation directions. The two sections of thread are respectively threadedly connected to the two threaded seats 702. The lower end of the rotating arm 701 is rotatably connected to a plug-in plate 704, and also includes a plug-in platform 9. The surface of the plug-in platform 9 is provided with a groove that matches the plug-in plate 704. In a preferred embodiment, the plug-in plate 704 is a disc.

The plug-in platform 9 is a block-shaped structure, and a "U"-shaped or semicircular structure is arranged on the surface of the plug-in platform 9. When installing the device, the rack body 1 needs to be hoisted to the installation position. The plug-in plate 704 rotating at the bottom of the mounting bracket 7 can assist the device to move in a small range, thereby reducing the difficulty of installation. When installing the device, first determine the installation position of the mounting arm 8 according to the working position of the device, pre-install the mounting arm 8, and then install the mounting arm 8 according to the mounting arm 8. The plug-in platform 9 is positioned and installed at the position, and the threaded rod 703 is rotated. The distance between the two threaded seats 702 can be adjusted by the threaded transmission of the threaded seat 702 and the threaded rod 703. The threaded seat 702 rotates around the outer wall of the rack body 1, and the distance between the two plug-in plates 704 can be adjusted. The plug-in plates 704 are adjusted to correspond to the grooves on the plug-in platform 9, and the bolts on the mounting arm 8 are loosened, so that the rack body 1 can be rotated a small degree around the bolts on the mounting arm 8, which can be a rotation within the range of 5°-10°. The plug-in plate 704 is assisted in being plugged in and placed, and then the plug-in plate 704 is installed and limited by bolts, and the mounting arm 8 is reinforced by bolts to realize the overall fixation of the rack body 1. During the rotation of the rotating arm 701 around the rack body 1, the vertical distance between the rack body 1 and the plug-in platform 9 will produce a corresponding change. The height of the plug-in platform 9 needs to be installed according to the actual situation. During the installation of the device, only the corresponding jack tool needs to be used to realize rapid positioning and installation. Furthermore, a limit block is provided at the outer end of the threaded rod 703.
