The fixed part is fixedly installed on the fence, and one side of the rotating part is rotatably connected to the fixed part. A plurality of spraying heads are installed on the rotating part; the fixed part and the rotating part have two states, namely an open state and a closed state; in the closed state, the other sides of the fixed part and the rotating part are in contact with each other, and the two form a cavity structure, and the spraying head is located inside the cavity structure; in the open state, the other side of the fixed part and the other side of the rotating part are separated, and the spraying head is exposed to the air, and the spraying head faces away from the fence and outwards.

[0033] In this embodiment, by providing a protective mechanism on the enclosure, a plurality of [components] are installed on the rotating part of the protective structure. When the sprinkler head needs to be used, the protective structure is switched from the closed state to the open state by rotating the rotating part, and the sprinkler head is taken out from the cavity structure for daily dust suppression operations. After the dust suppression operation is completed, the protective structure is switched from the open state to the closed state by rotating the rotating part, so as to realize the storage of a plurality of sprinkler heads into the cavity structure.

[0034] Based on the above structure, it is avoided that the sprinkler head is exposed when not working, the probability of accidental damage to the sprinkler head is reduced, the protection measures for the sprinkler head are improved, so that the sprinkler head can be used normally, and the efficiency of the municipal engineering in using the sprinkler head for dust suppression work is improved.

[0037] Embodiment 2

[0038] The structure and principle of Embodiment 2 are similar to those of Embodiment 1. The difference lies in that: a preferred form of the fixing structure is given. The fixing structure includes a slider 4-31, a connecting rod 4-32, a limiting disc 4-33, and a spring 4-34; a chute 4-35 matching the size of the limiting disc is provided in the slider, a through hole matching the connecting rod is provided at one end of the slider, and the through hole communicates with the guiding groove; the limiting disc is placed in the chute, one end of the connecting rod is connected to the connecting plate, and the other end of the connecting rod passes through the through hole and is connected to the limiting disc; the spring is located between the side wall of the slider where the through hole is located and the limiting disc;

[0039] A first fixing groove 4-36 matching the slider is provided on the outer frame; when the connecting plate and the outer frame are in a fitting state and there is no external force, part or all of the slider is located in the first fixing groove; when an external force acts on the slider, the slider completely disengages from the first fixing groove. By providing the first fixing groove, the slider can be normally inserted into the interior of the outer frame, so that when the sprinkler head is not working, the connecting plate and the outer frame can be fixed by using the slider and the first fixing groove, and the sprinkler head is fixed inside the outer frame, reducing the probability of accidental damage to the sprinkler head exposed outside.

[0040] The spring is used in cooperation with an external force to drive the slider to move on the connecting rod. When the connecting plate and the outer frame are switched from the closed state to the open state, the external force acts on the slider, and the slider disengages from the first fixing groove; due to the lack of limitation between the slider and the first fixing groove, the rotating plate can rotate freely on the outer frame. After the dust reduction operation is completed, the rotating plate is rotated to the closed state; during this process, the external force acts on the slider, and the slider slides along the connecting rod in a direction away from the connecting plate; after the slider is aligned with the first fixing groove, the acting force on the slider is withdrawn, and at this time, the slider slides into the first fixing groove to fix the states of the connecting plate and the outer frame.

[0041] In this embodiment, one or two sets of fixing structures are provided on the connecting plate, and the fixing structures are arranged on the side wall surface of the connecting plate.

[0042] Embodiment 3

[0043] The structure and principle of Embodiment 3 are similar to those of Embodiment 2. The difference lies in that in order to fix the connecting plate in the open and closed states and prevent the sprinkler head from shaking during the dust reduction operation, a fixing block 5 is further provided on the outer frame, and a second fixing groove 4-37 is provided on the fixing block. The size of the second fixing groove matches the size of the first fixing groove; the fixing block is located below the connecting plate, and when the connecting plate and the outer frame are in the open and closed states, the slider slides into the second fixing groove. By providing the second fixing groove, the slider can move on the fixing block, so that when the sprinkler head is working, the connecting plate can be fixed by means of the slider and the fixing block, and good fixing measures are provided after the connecting plate is opened to prevent the sprinkler head from being unstable during the working process.

[0044] In Embodiments 2-3, one end of the spring is welded and fixed to the inner wall of the slider chute at the through hole.

[0045] Embodiment 4

[0046] The structure and principle of Embodiment 4 are similar to those of Embodiment 2. The difference lies in that a plurality of fixing frames 4-5 are fixedly provided on the side surface of the connecting plate located in the cavity structure, and a plurality of installation grooves are provided on the fixing frames, and each installation groove is provided with a sprinkler head.

[0047] In Embodiment 4, a bifurcated pipe 4-6 is further included, and all the sprinkler heads are connected to the bifurcated pipe; the bifurcated pipe is connected to the water supply pipe.

[0048] The working principle of the present utility model:

[0049] During use, first pull the slider to move. The slider slides on the outer surface of the connecting rod and gradually moves out from the inside of the outer frame. The limit disc moves inside the slider. During the process of pulling the slider, the spring is affected by the pulling force and its shape gradually changes until the slider is completely pulled out from the first fixed groove of the outer frame. Keep the position of the slider unchanged after pulling, and drag the slider to move to open the connecting plate. As the connecting plate swings open, the fixing frame moves along with the movement of the connecting plate and moves the sprinkler head out from the inside of the outer frame until the slider is dragged to move to the fixed block and the connecting plate is completely open. Keep the position of the completely opened connecting plate unchanged, release the pulled slider, and the spring is no longer affected by the pulling force and its shape gradually resumes; and during the process of shape resuming, it drives the slider to move, and the slider actively resumes its position; and it slides on the outer surface of the connecting rod. As the pulled position of the slider gradually resumes, the slider gradually inserts into the inside of the fixed block; and fixes the position after the connecting plate is opened, so that the sprinkler head maintains good position stability after being moved out. Use the sprinkler head to supply water through the water supply channel. The water source enters the inside of the bifurcated pipe from the water supply pipe and enters the inside of the sprinkler head through the bifurcated pipe. The sprinkler head sprays out the water source to perform dust suppression treatment on the surrounding environment.

[0050] The above are only the preferred embodiments of the present invention and do not impose any form of limitation on the present invention; any ordinary technician in the industry can smoothly implement the present invention as shown in the accompanying drawings of the specification and described above; however, any minor changes, modifications, and equivalent variations made by those skilled in the art within the scope of the technical solution of the present invention by using the technical content disclosed above are all equivalent embodiments of the present invention; at the same time, any equivalent changes, modifications, and variations made to the above embodiments based on the essence of the present invention still fall within the protection scope of the technical solution of the present invention.
