For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0026] The utility model provides a technical solution:

[0027] Example 1

[0028] Combine Figures 1 to 6 A dustproof canopy used in foundation pit excavation construction includes a dustproof canopy main body 3, a support rod 4 is fixedly connected to the bottom of the dustproof canopy main body 3, a cross bar 41 is fixedly connected to the top of the support rod 4, a dust reduction mechanism 1 is arranged on the outside of the support rod 4, and a fixing mechanism 2 is arranged on the inside of the dust reduction mechanism 1.

[0029] The dust reduction mechanism 1 includes a battery life component 11 , an installation component 12 and a dust reduction component 13 . The battery life component 11 is arranged on the outside of the support rod 4 , the installation component 12 is arranged on the inside of the battery life component 11 , and the dust reduction component 13 is arranged inside the battery life component 11 .

[0030] The battery life component 11 includes a water tank 1101, which is arranged on the outside of the support rod 4.

The inner side of the sleeve rod 1202 is fixedly connected with a reinforcing fin 1204, the reinforcing fin 1204 is clamped in the bottom of the sleeve frame 1201, the reinforcing fin 1204 is fixedly connected to the top of the connecting block 1203, the dust reduction component 13 includes a water pump 1301, the water pump 1301 is fixedly connected to the bottom of the water tank 1101, the top of the water pump 1301 is fixedly connected with a water pipe 1302, the water pipe 1302 is sleeved in the top of the water tank 1101, and the inside of the water pipe 1302 is fixedly connected with a sprinkler head 1303.

[0031] Furthermore: the sprinkler head 1303 arranged on the outside of the dust-proof canopy main body 3 sprays water mist on the construction inside below the dust-proof canopy main body 3, and physically reduces the dust generated by the construction, thereby increasing the dust reduction effect of the dust-proof canopy main body 3 on the construction road surface when in use, and reducing the pollution and impact of the construction on the surrounding environment. At the same time, the setting of the water tank 1101 allows the sprinkler head 1303 to be disconnected from the water pipe and work for a long time, so that the device can be adapted to some remote areas without water pipe connections when in use, thereby increasing the scope of use of the device.

[0032] Example 2

[0033] See Figures 1 to 6 On the basis of Example 1, it is further obtained that the fixing mechanism 2 includes a hanging component 21, an adjusting component 22 and a clamping component 23, the hanging component 21 is arranged on the outside of the cross bar 41, the adjusting component 22 is arranged on the outside of the hanging component 21, and the clamping component 23 is arranged on the inside of the hanging component 21.

[0034] The hanging assembly 21 includes a hanging plate 2101, which is arranged below the sprinkler head 1303. The inner side of the hanging plate 2101 fits against the outer side of the cross bar 41. The inner side of the hanging plate 2101 is fixedly connected to an L-shaped bracket 2102. The L-shaped bracket 2102 is sleeved on the top of the cross bar 41. The top of the hanging plate 2101 is fixedly connected to a supporting sleeve 2103. The supporting sleeve 2103 is sleeved on the outer ring of the water pipe 1302. The adjusting assembly 22 includes a threaded shaft 2201. The threaded shaft 2201 is arranged on the outer side of the hanging plate 2101. The bottom of the threaded shaft 2201 is fixedly connected to a torsion disk 2202. The top of the threaded shaft 2201 is rotatably connected to a support rotating frame 1 2203. The support rotating frame 1 2203 is fixedly connected to the outer top of the hanging plate 2101. The bottom of the outer ring of the threaded shaft 2201 is rotatably connected to a support rotating frame 2 2204, the supporting rotating frame 2204 is fixedly connected to the bottom outer side of the hanging plate 2101, and the clamping assembly 23 includes a threaded cylinder 2301, the threaded cylinder 2301 is threadedly connected to the outer ring of the threaded rotating shaft 2201, and the inner side of the threaded cylinder 2301 is fixedly connected to a movable slide rod 2302, and the movable slide rod 2302 is slidably connected to the hanging plate 2101, and the inner top of the movable slide rod 2302 is fixedly connected to an L-shaped splint 2303, and the L-shaped splint 2303 is clamped to the bottom of the cross bar 41, and the bottom of the L-shaped splint 2303 is fixedly connected to a limiting slide rod 2304, and the outer side of the limiting slide rod 2304 is slidably connected to a slide rail 2305, and the slide rail 2305 is fixedly connected to the inner side of the hanging plate 2101, and the outer side of the limiting slide rod 2304 is fixedly connected to a limiting plate 2306, and the inner side of the limiting plate 2306 fits with the outer side of the slide rail 2305.

[0035] Furthermore, the staff only needs to rotate the torsion plate 2202 to drive the L-shaped splint 2303 upward, so that the L-shaped splint 2303 can cooperate with the L-shaped bracket 2102 to fix the hanging plate 2101 to the outside of the cross bar 41, which is convenient for the staff to fix and disassemble the sprinkler head 1303 and to disassemble and assemble the water tank 1101. The operation is simple and convenient for the staff to use.

[0036] In actual operation, when this device is used, the staff first fills the water tank 1101 with water, and then starts the water pump 1301. The water pump 1301 starts to spray the water in the water tank 1101 through the water pipe 1302 through the spray head 1303. The spray head 1303 atomizes the sprayed water. The sprayed water mist comes into contact with the dust in the air and increases its weight, causing it to fall downward under the action of gravity. At this time, the dust reduction treatment for construction dust is completed;

[0037] When the sprinkler head 1303 needs to be disassembled, the staff first rotates the torsion disk 2202. The rotation of the torsion disk 2202 drives the threaded shaft 2201 to rotate. The rotation of the threaded shaft 2201 drives the threaded barrel 2301 to move downward. The threaded barrel 2301 moves downward and drives the L-shaped clamping plate 2303 to move downward through the moving slide rod 2302. The L-shaped clamping plate 2303 moves downward to release the cooperation with the L-shaped bracket 2102, and loses the clamping of the cross bar 41. At this time, the staff only needs to move the hanging plate 2101 upward and then outward to complete the disassembly of the hanging plate 2101.

[0038] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
