[0002] With the development of the economy and the acceleration of industrialization, the natural environment has also been damaged. The advancement of urbanization has led to a decrease in land vegetation coverage, reducing the role of vegetation in purifying the air. Urban construction has increased dust in the air and also induced haze.

[0003] A Chinese patent publication (publication number: CN216935232U) discloses a small street spray dust reduction environmental protection device, which includes a bottom plate, which is the main supporting structure of the device, a caster is arranged at the bottom end of the bottom plate, and a movable shaft is connected inside the caster; a water tank is located at the top of the bottom plate, a water pump is installed inside the water tank, and a water supply pipe is arranged at the top of the water tank; a support frame is located at the top of the water tank, and a rotating disk is connected between the water tank and the support frame; a fog cannon is located on the inner surface of the support frame, and a connecting shaft is arranged at the connection between the fog cannon and the support frame;

[0004] When the device is in use, the fog cannon is installed on the support frame for fixing through a connecting shaft, but the structure lacks an angle-adjustable component, resulting in the fog cannon being able to spray only at a fixed angle, reducing the coverage and effect of the spray dust reduction. Therefore, a spray-type environmentally friendly dust reduction device is proposed. Utility Model Content

[0023] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0024] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-4 As shown, an embodiment of the utility model provides a device body 1, a rotating bracket 2 is fixedly installed on the top of the device body 1, a fog cannon 3 is rotatably connected to the top of the rotating bracket 2, a first gear 4 is fixedly installed on a rotating head on one side of the fog cannon 3, a side bracket 5 is welded to one side of the rotating bracket 2, a rotating shaft 6 is rotatably connected to the top of the side bracket 5, a second gear 7 is fixedly installed on one end of the rotating shaft 6, and the second gear 7 is meshingly connected to the first gear 4. The device is conducive to controlling the adjustment of the spray angle of the fog cannon 3, thereby improving the coverage range and dust reduction effect of controlling the spray dust reduction.

[0026] In one embodiment, the inner wall of the side bracket 5 is fixedly connected to a fixing frame 8, the top of the fixing frame 8 is fixedly connected to a supporting plate 9, the inner wall of the supporting plate 9 is rotatably connected to a self-locking head 10, the self-locking head 10 can rotate on the supporting plate 9, and can be rotated and contacted for self-locking as needed, the outer wall of the rotating shaft 6 is fixedly connected to a toothed disc 11, the teeth of the self-locking head 10 are stuck on the teeth of the toothed disc 11, and the teeth of the self-locking head 10 can be stuck on the teeth of the toothed disc 11, so as to control the rotation of the rotating shaft 6 and fix the angle of the fog cannon 3, thereby avoiding the problem of the rotating shaft 6 rotating due to the heavier weight on one side of the fog cannon 3.

[0027] In one embodiment, a spring 13 is fixedly connected to one side of the self-locking head 10, and the spring 13 is used to push the self-locking head 10 against the toothed disc 11. A pull rod 12 is fixedly connected to one side of the self-locking head 10, and the pull rod 12 is inside the spring 13, and one end of the pull rod 12 passes through the top of the fixing frame 8. By pulling the pull rod 12, the self-locking head 10 can be removed from the toothed disc 11 to release the self-locking, and the rotating shaft 6 can be shaken to increase the angle of the fog cannon 3.

[0028] In one embodiment, a water tank 14 is fixedly installed inside the device body 1. The water tank 14 is used to store a portion of water in advance for temporary use when it is inconvenient to connect a water pipe, so as to ensure that there is enough water for dust reduction. A water inlet pipe 16 is fixedly installed on one side of the water tank 14, and a high-pressure water pump 15 is fixedly installed on one side of the water tank 14. A water pipe 17 is fixedly installed on one side of the high-pressure water pump 15, and the other end of the water pipe 17 is fixedly installed on the atomization joint of the fog cannon machine 3. The water in the water tank 14 can be transported to the fog cannon machine 3 through the high-pressure water pump 15, which can increase the water pressure of the transport and ensure that the fog cannon machine 3 can spray a large amount of fog for dust reduction.

[0029] In one embodiment, the diameter of the first gear 4 is greater than the diameter of the second gear 7. By driving the first gear 4 with a larger diameter with the second gear 7 with a smaller diameter, the transmission ratio can be reduced, and the angle of the fog cannon 3 can be accurately adjusted. The number of teeth of the first gear 4 is greater than that of the second gear 7. By controlling the number of teeth of the first gear 4 and the second gear 7, when the second gear 7 drives the first gear 4, there is no need to apply excessive force to rotate the shaft, and the torque can be increased, thereby achieving a labor-saving effect.

[0030] In one embodiment, the fixing frame 8, the supporting plate 9, the self-locking head 10, the spring 13 and the pull rod 12 are fixedly mounted on the side bracket 5 on the spray side of the fog cannon 3. By installing the self-locking head 10 and other structures on the spray side, the toothed disc 11 can be locked to control the rotation of the rotating shaft 6 and fix the angle of the fog cannon 3, thereby avoiding the problem of the rotating shaft 6 rotating due to the heavier weight on one side of the fog cannon 3.

[0031] In one embodiment, the distance from the rotating connection of the outer wall of the fog cannon 3 to the bottom of the rotating bracket 2 is greater than the distance from the rotating connection to the tail end of the fog cannon 3. By rotating the fog cannon 3 to the position of the rotating bracket 2, it is ensured that when the angle of the fog cannon 3 is adjusted, the problem of the tail end of the fog cannon 3 hitting the bottom of the rotating bracket 2 due to distance problems can be avoided, thereby increasing the range of the adjustment angle.

[0032] When the utility model is working: when the angle of the fog cannon 3 is increased, the rotating shaft 6 is directly shaken to drive the second gear 7 to rotate, and the second gear 7 transmits the rotation force to the first gear 4 in meshing rotation, and the first gear 4 can drive the fog cannon 3 to rotate on the rotating bracket 2, thereby achieving the adjustment of the spray angle of the fog cannon 3;

[0033] When the angle of the fog cannon is reduced, the pull rod 12 can be pulled to release the self-locking of the self-locking head 10, and the locking teeth of the self-locking head 10 will leave the gear disk 11, and then the angle can be adjusted by shaking the rotating shaft 6. When the angle adjustment stops, the pull rod 12 is released and the elastic force of the spring 13 can push the self-locking head 10 to be stuck on the gear disk 11, so that the teeth of the gear disk 11 are stuck and cannot rotate, thereby fixing the angle of the fog cannon 3.

[0034] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
