[0024] The side wall of the fixing block 53 has a triangular protrusion. When the user moves the moving block 51 to contact the self-rewinding shaft 5, the fixing block 53 will be pushed by the edge of the groove that mates with the fixing block 53. The moving block 51 continues to move, and the fixing block 53 enters the groove that mates with it under the action of the spring. At this time, the moving block 51 is fixed on the self-rewinding shaft 5 through the cooperation of the fixing block 53 and the groove that mates with it, ensuring the stability of the moving block 51 during the use of the device. The moving block 51 is provided with several fixing blocks 53 to ensure the fixing effect of the fixing blocks 53 on the moving block 51. The spring provided on the fixing block 53 ensures that the fixing block 53 can quickly return to its original position after being pushed, ensuring the fixing effect of the fixing block 53 on the moving block 51. The shape of the protrusion on the side wall of the fixing block 53 ensures that the user will not be obstructed when installing the moving block 51 on the self-rewinding shaft 5 and removing the moving block 51 from the self-rewinding shaft 5.

[0025] Specifically, the side wall of the fixing block 53 is provided with a sealing plate, and the side wall of the groove for installing the fixing block 53 is provided with a groove that cooperates with the side wall sealing plate of the fixing block 53.

[0026] The side wall sealing plate of the fixing block 53 and the corresponding groove will seal the groove for installing the fixing block 53, preventing external debris from entering the groove for installing the fixing block 53 during the use of the device, and ensuring that the movement of the fixing block 53 will not be hindered. Both sides of the fixing block 53 are provided with sealing plates to ensure that the groove for installing the fixing block 53 remains closed during the movement of the fixing block 53.

[0030] The fit between the side wall protrusion of the base 1 and the groove of the protective net 2 on the base 1 ensures the stability of the protective net 2 after it is installed on the base 1. This ensures that the protective net 2 will not move during the process of the user installing the pressure plate 3 on the protective net 2, making it convenient for the user to install the protective net 2 and the pressure plate 3.

[0031] Specifically, the extension rod 61 is slidably mounted on the side wall groove of the slot for mounting the extension rod 61, and the side wall of the extension rod 61 is provided with a groove that cooperates with the side wall protrusion of the fixing plate 62.

[0032] The extension rod 61 is slidably installed in the groove for mounting the extension rod 61. When the device is in use, the extension rod 61 is moved and inserted into the ground, ensuring the stability of the support plate 6 during the use of the device. The cooperation between the side wall protrusion of the fixing plate 62 and the side wall groove of the extension rod 61 plays the role of fixing the extended rod 61 after it is moved, ensuring the stability of the extension rod 61 during the use of the device.

[0033] Specifically, the bottom of the base 1 is provided with several drainage grooves 11, and the side wall of the groove on which the movable block 51 is installed in the base 1 is provided with several drainage holes 12.

[0034] When water accumulates in the construction site, the drainage trough 11 on the base 1 can quickly drain the water from the construction site, and the drainage hole 12 can drain the water inside the groove where the movable block 51 is installed.

[0035] The working principle and usage process of this utility model are as follows: The device is installed on the ground using a fixing nail device. The support plate 6 is unscrewed from its groove. The bidirectional threaded rod is rotated, causing the two fixing plates 62 to move back and forth, releasing the fixing plate 62 from the extension rod 61. The extension rod 61 is then unscrewed from its groove and moved. The moved extension rod 61 is inserted into the ground, fixing the support plate 6. The bidirectional threaded rod is rotated in the opposite direction, causing the fixing plate 62 to return to its original position. The side wall protrusion of the fixing plate 62 enters the corresponding groove, fixing the extension rod 61. The protective net 2 and pressure plate 3 are then installed sequentially on the base 1, and the pressure plate 3 is fixed with screws. During dust suppression, the water storage tank 7 is activated. The device uses atomizing nozzles to spray water from the water tank 7 into the outside environment through the spray channel 71, thus reducing dust at the construction site. When the wind is too strong, two electric drums 54 are activated to wind and release the pull line. The moving block 51 moves under the action of the pull line, pulling the sealing cloth 52 out of the self-rewinding shaft 5. As the moving block 51 moves, the fixing block 53 is pushed. When the moving block 51 is in contact with the self-rewinding shaft 5, the fixing block 53 enters the groove that matches it under the action of the spring, and the moving block 51 is fixed. The pulled-out sealing cloth 52 seals the protective net 2, preventing the outside wind from having an adverse effect on the construction site.
