[0048] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the protection scope of the present invention.

[0049] Please refer to Figures 1-10 , the present invention provides a technical solution:

[0050] A buried rotary multi-angle channel high-pressure flushing device based on a Venturi nozzle, including a buried device body 1 and a movable nozzle assembly 2;

[0051] The buried device body 1 includes a device protection shell 3, an outer cylinder 4 and an intermediate cylinder 5. The outer cylinder 4 is arranged inside the device protection shell 3, and the intermediate cylinder 5 is arranged inside the outer cylinder 4;

[0052] The bottom of the outer cylinder 4 is rotationally connected to the device protection shell 3 through a flange bearing 14. A spiral chute 7 is opened on the wall of the outer cylinder 4. A top notch 9 is opened at the starting point of the top of the spiral chute 7, and a bottom notch 1 is opened at the end point of the bottom. 0;

[0053] The intermediate cylinder 5 is internally provided with a movable nozzle assembly 2. The movable nozzle assembly 2 includes an inner cylinder 201. When the outer cylinder 4 rotates, the inner cylinder 201 can rise upward. A slider 206 is provided on the outer wall of the inner cylinder 201, and the slider 206 can cooperate with the spiral chute 7. The slider 206 passes through the spiral chute 7. A vertical chute 8 is opened on the intermediate cylinder 5. The slider 206 can cooperate with the vertical chute 8. The slider 206 passes through the vertical chute 8. When the slider 206 slides to the up and down stroke positions, it can stop in the top notch 9 and the bottom notch 10.

[0054] The keyway opened on the wall of the outer cylinder 4 is matched with a large gear through a key 15. The large gear is sleeved and installed on the outer side of the wall of the outer cylinder 4. A motor 12 is installed on the device protection shell 3 through a motor bracket 13, and a gear 11 is installed at the output end of the motor 12. The gear 11 meshes with and drives the large gear.

[0055] When road surface cleaning is required, the motor 12 is controlled to rotate. The motor 12 drives the gear 11 to rotate, and the gear 11 drives the large gear to rotate. When the large gear rotates, the key 15 drives the outer cylinder 4 to rotate on the flange bearing 14. Since the slider 206 on the outer wall of the inner cylinder 201 can slide in the spiral chute 7 and the vertical chute 8 at the same time, the inner cylinder 201 can be spirally lifted during the rotation of the outer cylinder 4.

[0056] A mounting bracket 202 is installed inside the inner cylinder 201. The inside of the mounting bracket 202 is movably connected to the electric push rod 203 through a hinge 205. The other end of the electric push rod 203 is hingedly installed with a nozzle 204. The bottom end of the nozzle 204 is hinged to one side of the mounting bracket 202. The nozzle 204 can be retracted inside the mounting bracket 202 when idle, achieving the functions of protection and concealment.

[0057] The bottom of the device protective shell 3 is connected to a connector 17 that is threadedly fixed to the water supply pipe. The connector 17 is connected to the high-pressure hose 16, and the high-pressure hose 16 is connected to the water supply end of the nozzle 204. A vertical opening 209 is provided on the barrel wall of the inner cylinder 201. The nozzle 204 makes adjustments to the up and down spraying angles within the range of the opening 209.

[0058] To further enhance the cleaning effect of the nozzle 204, the nozzle 204 adopts a critical Venturi nozzle, which can increase the velocity of the ejected water flow.

[0059] The mounting bracket 202 is connected to the bracket cover 208. The bracket cover 208 is connected to the inner cylinder 201 in a resting manner. A flange 6 is fixedly installed on the device protective shell 3, and the flange 6 covers the upper part of the intermediate cylinder 5.

[0060] During use, the device protection shell 3 of the buried device body 1 is buried underground, and the connecting piece 17 at the bottom of the device protection shell 3 is connected and fixed to the water pipe of the high and low pressure water supply system. When the device is working, the motor 12 drives the outer cylinder 4 to rotate through the gear 11. The slider 206 on the outer wall of the inner cylinder 201 moves under the restriction of the spiral chute 7 and the vertical chute 8, thereby driving the inner cylinder 201 to rise. After the movable nozzle assembly 2 rises to the highest position, the slider 206 moves to the top notch 9 of the spiral chute 7 to maintain the height and stability of the device. During the cleaning operation, the system supplies high-pressure water to the high-pressure hose 16 inside the device. At this time, the electric push rod 203 contracts under the drive of electricity, so that the nozzle 204 sprays downward within a certain angle range to achieve the cleaning of the ground. The change in the spraying angle of the nozzle 204 not only enhances the cleaning ability of the device but also reduces the cleaning dead angle. During the dust suppression operation, the system supplies low-pressure water to the high-pressure hose 16 inside the device. The electric push rod 203 extends under the drive of electricity, so that the nozzle 204 can spray upward within a certain angle range. The sprayed water will settle the dust particles in the air to the ground to achieve dust suppression. After the work is completed, the motor 12 rotates in reverse, driving the outer cylinder 4 to rotate in reverse. The slider 206 on the outer wall of the inner cylinder 201 moves under the restriction of the spiral chute 7 and the vertical chute 8 again, thereby driving the inner cylinder 201 to descend. When the movable nozzle assembly 2 descends to the lowest position, the slider 206 moves to the bottom notch 10 of the spiral chute 7 to achieve the closing of the device. After the device is closed, it can be completely hidden underground, without blocking the integrity of the road surface landscape, maintaining a good visual experience, and is particularly suitable for roads with high requirements for greening landscapes, meeting both the cleaning needs and protecting the greening achievements, achieving the perfect integration of functionality and concealment.

[0061] It is worth noting that in actual applications, due to its buried design, the retractable road cleaning device of the present invention can be flush with the ground when not in use and rise when in use. Therefore, it can also be installed at intersections or doorways and used as a roadblock.
