[0024] Example:

[0025] As attached Figure 1 To Attachment Figure 5 As shown:

[0026] The utility model provides a temporary dust prevention device for road construction, comprising a first column 1 and a second column 2, the first column 1 and the second column 2 are symmetrically arranged, the first column 1 is provided with a first mounting groove 3 on a side close to the second column 2, a first mounting rod 4 is rotatably mounted at the bottom end of the first mounting groove 3, a first filter screen 5 is mounted on one side of the first mounting groove 3, a plurality of hanging rings 6 are mounted on one side of the first filter screen 5, a second mounting groove 7 is provided on the second column 2 on a side close to the first column 1, a second mounting rod 8 is rotatably mounted on the top end of the second mounting groove 7, a plurality of dust inlet ports 9 are arranged on one side of the second mounting rod 8, a spherical block 10 is mounted on the second mounting rod 8 and the first mounting rod 4 on a side away from each other, a hook 11 is mounted on one side of the second mounting groove 7 at a position parallel to each hanging ring 6, a dust suction mechanism is mounted on the top end of the second mounting groove 7, and a locking mechanism is mounted on the top end of the first mounting groove 3 and the bottom end of the second mounting groove 7.

[0027] Among them, the locking mechanism includes two slide grooves 12, and the two slide grooves 12 are respectively opened at the top end of the first mounting groove 3 and the bottom end of the second mounting groove 7. A pair of sliders 13 are slidably installed on both sides of the slide groove 12. The pair of sliders 13 are each provided with a hemispherical groove 14 on the opposite side, and the size of the hemispherical groove 14 matches the size of the spherical block 10. The spherical block 10 is fixed between the pair of sliders 13 through the hemispherical groove 14 between the pair of sliders 13, thereby realizing the fixation of the first mounting rod 4 and the second mounting rod 8. When disassembling the first mounting rod 4 and the second mounting rod 8, the spherical block 10 can be detached from the pair of hemispherical grooves 14 by controlling the pair of sliders 13 to move away from each other, thereby realizing disassembly.

[0028] Among them, compression springs 15 are installed on both sides of the two slide grooves 12, and the other end of the compression spring 15 is connected to the slider 13. When the spherical block 10 needs to be inserted into a pair of hemispherical grooves 14, the spherical block 10 installed on one side of the first mounting rod 4 or the second mounting rod 8 first contacts with a pair of inclined blocks 16. By squeezing the pair of inclined blocks 16, the pair of sliders 13 are moved away from each other, thereby realizing the insertion of the spherical block 10 into the pair of hemispherical grooves 14. Under the action of the rebound of the compression spring 15, the pair of sliders 13 clamp the spherical block 10.

[0029] The bottom ends of the pair of sliding blocks 13 in the first mounting groove 3 and the side away from the first mounting groove 3 are both installed with inclined blocks 16 to facilitate the spherical block 10 to be inserted into the pair of hemispherical grooves 14 .

[0030] The top of the pair of sliding blocks 13 in the second mounting groove 7 and the side away from the second mounting groove 7 are both installed with inclined blocks 16 to facilitate the spherical block 10 to be inserted into the pair of hemispherical grooves 14 .

[0031] Among them, the dust suction mechanism includes a dust box 17, a second filter 18 is installed at the middle position inside the dust box 17, an electric fan 19 is installed at the bottom end of the dust box 17, and an air outlet is provided at the bottom end of one side of the dust box 17 at a position close to the output end of the electric fan 19. A dust inlet duct 20 is installed at the top of the dust box 17, and the dust inlet duct 20 is connected with the dust inlet 9. When the electric fan 19 is turned on, the electric fan 19 discharges the air in the dust box 17 from the air outlet, so that negative pressure is instantly generated in the dust box 17. At this time, the dust-laden air enters the dust box 17 from the dust inlet 9 through the dust inlet duct 20 and adheres to the second filter 18, thereby achieving dust adsorption.

[0032] The working principle of this embodiment is as follows: when it is necessary to use the temporary dustproof device, the staff first places the first column 1 and the second column 2 to the appropriate position, and then pushes the inclined blocks 16 installed at the bottom ends of the pair of sliders 13 in the first mounting groove 3 in opposite directions, controls the pair of sliders 13 to move away from each other, and allows the spherical block 10 to disengage from the pair of hemispherical grooves 14, and then rotates the first mounting rod 4 to rotate the spherical block 10 on one side of the first mounting rod 4 to the top of the locking mechanism located at the bottom end of the second mounting groove 7, and presses the spherical block 10, the spherical block 10 first contacts and squeezes the inclined blocks 16, so that the pair of sliders 13 move away from each other, and then the spherical block 10 is clamped into the pair of hemispherical grooves 14, and under the action of the rebound of the compression spring 15, the pair of sliders 13 clamp the spherical block 10, and the staff repeats the above operation to The spherical block 10 on one side of the mounting rod 8 is installed in the locking mechanism located at the top of the first mounting groove 3. After the installation is completed, the first filter screen 5 is pulled so that each hook 11 is hooked into the hanging ring 6, and the first filter screen 5 can be unfolded and fixed. During the construction process, the electric fan 19 is turned on, and the electric fan 19 discharges the air in the dust box 17 from the air outlet, so that a negative pressure is instantly generated in the dust box 17. At this time, the dust-laden air enters the dust box 17 from the dust inlet port 9 through the dust inlet pipe 20 and adheres to the second filter screen 18 to achieve dust adsorption. After the construction is completed, the staff first controls the first filter screen 5 to reset, and then disengages the spherical blocks 10 on one side of the first mounting rod 4 and the second mounting rod 8 from the locking mechanism respectively, and rotates the first mounting rod 4 into the first mounting groove 3, and the second mounting rod 8 into the second mounting groove 7, so that recycling can be achieved.
