[0030] A plurality of circular grooves are formed in the front part of the outer surface of the telescopic column 7.

[0031] In the device, the external water pipe 5 is connected with an external water pump, so that the external water pump can deliver water into the spraying mechanism 3 through the external water pipe 5.

[0032] In the above, after the external water pump is connected with the external water pipe 5, the spraying mechanism 3 can spray water mist to spray and reduce dust at the construction site; in addition, before the device is implemented, the fixing mechanism 2 can be pulled forward to release the fixing of the telescopic column 7, and then the telescopic column 7 can be pushed upward to move, so that the telescopic column 7 drives the spraying mechanism 3 to move upward, the height of the spraying mechanism 3 is adjusted, and the spraying mechanism 3 can spray according to the actual situation.

[0033] In the above, when the device needs to be stored or transported, the spraying mechanism 3 needs to be pressed first, so that the spraying mechanism 3 rotates from the horizontal state to the vertical state under the action of the limiting mechanism 6, the occupied space of the spraying mechanism 3 is reduced, then the fixing mechanism 2 is pulled to release the fixing of the telescopic column 7, so that the telescopic column 7 and the spraying mechanism 3 move downward due to gravity; secondly, the supporting device 8 is pushed upward to change the supporting device 8 from the expanded state to the contracted state, so that the occupied space of the supporting device 8 is reduced, then the device can be transported or stored, so that the device is more convenient to transport, occupies smaller space when stored, and thus the device can be used anytime and anywhere.

[0034] In the above, when the device is not used, the device can be used for support through the counterweight 4, which can increase the supporting force of the device and effectively improve the practicality of the device.

[0035] Further, in order to achieve the purpose of pushing the supporting device 8 to change the supporting device 8 from the expanded state to the contracted state, referring to Figure 2The support device 8 comprises three support rods 82 which are rotationally connected in an annular array to the lower part of the outer surface of the cylinder 1, a circular groove 84 is formed in the middle of the lower end of the cylinder 1, a sliding rod 81 is slidably connected in the inner cavity of the circular groove 84, and a rotating rod 83 is rotationally connected between the outer surface of the sliding rod 81 and one part of the three support rods 82 which are close to each other.

[0036] In the above, the sliding rod 81 is pushed upwards to slide in the inner cavity of the circular groove 84, and the sliding rod 81 is pulled to rotate the support rods 82 on the outer surface of the cylinder 1 to the side close to each other, so that the support rods 82 are rotated from the unfolded state to the contracted state, and the occupied space of the support rods 82 is reduced.

[0037] In the above, a damping coating is coated between the contact surface of the sliding rod 81 and the circular groove 84, so that the sliding rod 81 will not automatically slide downward in the vertical state.

[0038] Further, in order to realize the purpose of pulling the fixing mechanism 2, adjusting the height of the telescopic column 7 and the spraying mechanism 3, referring to Figure 3 and Figure 4 , the fixing mechanism 2 comprises a fixed shell 22 which is fixedly connected to the upper side of the front part of the outer surface of the cylinder 1, a pull rod 21 which is slidably connected in the inner cavity of the fixed shell 22, a circular ring 24 which is fixedly connected to the rear part of the outer surface of the pull rod 21, a pull spring 23 which is fixedly connected between the front end of the circular ring 24 and the front wall of the fixed shell 22, and the pull rod 21 which is in close contact with the circular groove.

[0039] In the above, the height of the telescopic column 7 can be adjusted by pulling the pull rod 21 to make it separate from the circular groove of the telescopic column 7; in addition, when the pull rod 21 is pulled, the circular ring 24 will slide in the inner cavity of the fixed shell 22 together with the pull rod 21, so that the circular ring 24 presses the pull spring 23 to generate pressure; when it is needed to fix the telescopic column 7 again, the pull rod 21 can be released to make the pull spring 23 release the pressure, push the circular ring 24 to move backward, make the circular ring 24 drive the pull rod 21 to move backward together, and make the pull rod 21 re-enter the circular groove of the telescopic column 7 to fix the telescopic column 7.

[0040] Further, in order to realize the purpose of dust falling of the spraying mechanism 3 and rotation of the spraying mechanism 3 from the horizontal state to the vertical state through the limiting mechanism 6, referring to Figure 5 , Figure 6 and Figure 7 , the spraying mechanism 3 comprises a water tank 34 which is fixedly connected to the upper end of the telescopic column 7, a water delivery pipe 32 which is rotationally connected to the left end and the right end of the water tank 34, a soft pipe 33 which is fixedly connected to the middle part of the end close to each other of the two water delivery pipes 32, and a plurality of water mist nozzles 31 which are fixedly connected to the front end and the rear end of the two water delivery pipes 32.

[0042] The limiting mechanism 6 comprises an arc-shaped shell 63 fixedly connected to the right upper side of the outer surface of the telescopic column 7, a limiting block 64 slidably connected to the left upper side in the inner cavity of the arc-shaped shell 63, a pressure spring 65 fixedly connected to the left end of the limiting block 64, a sliding module 62 slidably connected in the inner cavity of the arc-shaped shell 63, and an arc-shaped plate 61 rotatably connected to the right upper side of the sliding module 62, with the upper end of the arc-shaped plate 61 fixedly connected to the lower end of the water delivery pipe 32.

[0043] In the above, the external water pipe 5 is coupled with the external water pump, so that the external water pump delivers water into the water tank 34 through the external water pipe 5, and then the water tank 34 delivers water into the water delivery pipe 32 through the hoses 33, so that the water delivery pipe 32 sprays water through the water mist sprayer 31 to spray and reduce dust at the construction site.

[0044] In the above, when the water delivery pipe 32 needs to be retracted, the water delivery pipe 32 is first pressed to rotate the water delivery pipe 32 at the left and right ends of the water tank 34, and when the water delivery pipe 32 is rotated downward, the arc-shaped plate 61 is also rotated downward, and the arc-shaped plate 61 drives the sliding module 62 to slide downward in the inner cavity of the arc-shaped shell 63 through the rotatable connection between the arc-shaped plate 61 and the sliding module 62, and when the water delivery pipe 32 is rotated to the vertical state, the sliding module 62 slides to the bottom of the inner cavity of the arc-shaped shell 63 to occupy a smaller space.

[0045] In the above, the limiting mechanism 6 can also fix the water delivery pipe 32 in the horizontal state.

[0046] In the above, when the water delivery pipe 32 is rotated from the vertical state to the horizontal state, the sliding module 62 is driven to slide upward in the inner cavity of the arc-shaped shell 63, and when the sliding module 62 slides upward, the limiting block 64 slides to the left end of the arc-shaped shell 63 and presses the pressure spring 65 to generate pressure through the arc surface design of the limiting block 64, and when the water delivery pipe 32 is rotated to the horizontal state, the sliding module 62 is located at the highest position in the inner cavity of the arc-shaped shell 63, and at this time the pressure spring 65 releases the pressure to drive the limiting block 64 to slide to the right, so that the limiting block 64 limits the sliding module 62, and further fixes the water delivery pipe 32, so that the water delivery pipe 32 cannot be automatically rotated to the vertical state without external force.

[0047] In the above, the hoses 33 are telescopic hoses, so that when the water delivery pipe 32 is in the horizontal or vertical state, the hoses 33 do not affect the connection between the water delivery pipe 32 and the water tank 34.
