DETAILED DESCRIPTION

[0020] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0021] Please also refer to Figures 1 to 5 The elastic dust shield for roads and bridges according to the embodiment of the utility model will be described in detail below with reference to the accompanying drawings.

[0022] like Figure 1 As shown, the elastic dust-proof plate for road bridges comprises a fixed plate 1 and a dust-proof net 2 sliding inside the fixed plate 1, a bottom plate 3 is welded to the bottom of the fixed plate 1, a top plate 19 is fixed with screws on the top, a through slot 4 is provided on the top plate 19 for the dust-proof net 2 to slide out, a groove 5 is provided on the bottom plate 3, a mounting plate 6 is welded to the surface of the bottom plate 3 away from the groove 5, a driving member is rotatably connected to the bottom plate 3, and the driving member is used to drive the dust-proof net 2 to slide out along the through slot 4.

[0023] The shape of the top plate facing the dust-proof net 2 is consistent with the shape of the dust-proof net 2.

[0024] A brush 7 is fixed at the bottom of the top plate. A plurality of brushes 7 are arranged along the length direction of the top plate. The brushes 7 are arranged along one side of the through groove 4.

[0025] As an embodiment, the driving member includes a screw rod 8 rotatably connected to the inside of the base plate 3, a placement groove 9 is provided at the position of the base plate 3 corresponding to the screw rod 8, a connecting rod 10 is threadedly connected to the outside of the screw rod 8, one end of the connecting rod 10 is fixed to the side of the dust screen 2, a first bevel gear 11 and a second bevel gear 12 are provided inside the placement groove 9, the first bevel gear 11 is fixed to the outside of the screw rod 8, the second bevel gear 12 is meshed with the first bevel gear 11, a driving rod 13 is fixed to the outside of the second bevel gear 12, the driving rod 13 extends along one side of the placement groove 9 and extends to the outside of the base plate 3, and a driving plate 14 is fixed to the protruding end of the driving rod 13.

[0026] By rotating the driving plate 14, the driving plate 14 can drive the driving rod 13 to rotate, and then the second bevel gear 12 on the driving rod 13 starts to rotate, and then drives the first bevel gear 11 to rotate. When the first bevel gear 11 rotates, the first bevel gear 11 drives the screw rod 8 to rotate. Since the screw rod 8 is threadedly connected to the connecting rod 10, when the screw rod 8 rotates, the connecting rod 10 can move up and down, thereby driving the dust screen 2 to move up and down.

[0027] A guide rod 15 is fixed on the bottom plate 3 , and the guide rod 15 is symmetrically arranged with respect to the screw rod 8 . A cross rod 16 is slidably connected to the outside of the guide rod 15 , and one end of the cross rod 16 is fixed on the dust-proof net 2 .

[0028] The top plate is provided with a first through hole 17 for the guide rod 15 to be rotatably connected, and a second through hole 18 for the screw rod 8 to be rotatably connected is provided between the two first through holes 17 .

[0029] In this embodiment, the dust screen 2 is inserted into the fixed plate 1 and fixed at the upper end with a top plate screw. When the top plate 19 is installed with the screws, the first through hole 17 is aligned with the guide rod 15, and the second through hole 18 is aligned with the screw rod 8. After installation, the entire dust screen is installed on the road surface through the mounting plate 6 at the bottom of the base plate 3.

[0030] When the dust screen 2 needs to be cleaned, the driving plate 14 is rotated to drive the dust screen 2 to move upward. During the movement of the dust screen 2, the dust screen 2 moves upward out of the fixed plate 1. At the same time, during the movement, the side of the dust screen 2 contacts the brush 7 to scrape off the dust on the surface of the dust screen 2. The dust naturally falls into the groove 5 inside the bottom plate 3 and is collected, which is convenient for cleaning. After cleaning, the driving plate 14 is rotated in the opposite direction to move the dust screen 2 back to the inside of the fixed plate 1.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
