The speed bump body 1 in the present application document adopts the same technical means in this prior art. This technical means will not be described one by one here. For details about the improvement of this prior art, please refer to the disclosed technology below; to solve the technical problems existing in this prior art, as disclosed in the background technology above, "in a complex environment, dust in the air may cover the warning function locked on the device, reducing its visibility, which is not conducive to the required warning effect itself, and when the warning device is covered with dust, it still needs manual intervention and cleaning, which is not conducive to its convenience of use". In terms of combined use, this problem is obviously a real problem that exists and is relatively difficult to solve. In view of this, in order to solve the above problems, a cleaning component 2 and a reset component 3 are added on this basis.

[0029] More specifically:

[0030] like Figure 1-Figure 5 As shown:

[0031] In combination with the above content: it also includes a cleaning component 2 arranged on one side of the speed bump body 1, the cleaning component 2 includes a deformation plate 21, a rack 22, a stabilizing bar A23, an input gear 24, a stabilizing bar B25, an output gear 26, a coil 27, a pull rope 28, a warning rod 29, a warning sign 210, a stabilizing bar 211 and a cleaning grille 212, the surface of the speed bump body 1 is slidably connected with a rack 22 fixedly connected to the surface of the deformation plate 21, and the rack 22 is meshed with the surface of the input gear 24 inside the speed bump body 1, and the input gear 24 is rotatably connected to the stabilizing bar A23 fixedly installed on the inner surface of the deformation plate 21 At the same time, the other side of the input gear 24 away from the rack 22 is meshed with an output gear 26 fixedly connected to the coil 27. The output gear 26 is rotationally connected to a stabilizing bar B25 fixedly installed on the inner surface of the speed bump body 1. The surface of the coil 27 is also surrounded by a pull rope 28 that passes through the speed bump body 1 and extends from the inside of the warning rod 29 to the surface of the cleaning grille 212. The pull rope 28 is fixedly connected to the cleaning grille 212, and the warning rod 29 is also fixedly connected to the warning sign 210. The warning sign 210 is slidably connected to the surface of the cleaning grille 212. At the same time, the surface of the cleaning grille 212 is also slidably connected to the stabilizing bar 211.

[0032] In this embodiment, when a vehicle passes over the speed bump body 1, the wheel will press over the deformation plate 21 and squeeze the deformation plate 21 from an arc-shaped state to a flat state. At this time, the deformation plate 21 will push the rack 22 and the speed bump body 1 to slide through the deformed plane. At this time, the rack 22 will mesh with the small gear set on the surface of the input gear 24, and the stabilizing bar A23 and the input gear 24 will rotate. The stabilizing bar A23 can ensure the stability of the rotation of the input gear 24. At this time, the input gear 24 will rotate as a whole, and the large gear set on the surface of the input gear 24 will mesh with the output gear 26 and drive the output gear 26 and the coil 27 and the stabilizing bar B25 to rotate, and the coil 27 will generate When rotating, the coil 27 will pull the pull rope 28 wrapped around its surface. At this time, the pull rope 28 will pull the cleaning grille 212 set on the surface of the warning sign 210 along the inside of the warning rod 29, and enable the cleaning grille 212 to slide on the surface of the warning sign 210 toward the direction of the warning rod 29 and compress the spring 31 set thereunder. At this time, the stabilizing rod 211 set parallel to the surface of the warning sign 210 will slide between the cleaning grille 212 and keep the cleaning grille 212 stable. Then the wheel rolls over the surface of the deformation plate 21, and the deformation plate 21 returns to its original state. At this time, the coil 27 will also rotate in the opposite direction, and the pull rope 28 will be in a relaxed state when the coil 27 rotates in the opposite direction. Then the spring 31 will rebound and push the cleaning grille 212 back to its original position.

[0033] It should be noted that the pinion arranged on the surface of the input gear 24 has the same shape and size as the output gear 26 , and when the input gear 24 meshes with the output gear 26 , it can drive the output gear 26 to rotate more circles than the input gear 24 .

[0034] Going further:

[0035] In an optional embodiment, the shape of the deformable plate 21 is an arc-shaped plate.

[0036] In this embodiment, the arc-shaped deformation plate 21 can be deformed when a vehicle passes over it, and can further push the rack 22 to slide on the surface of the speed reduction belt body 1 when the deformation occurs, and effectively mesh with the input gear 24 .

[0037] It should be noted that the material of the deformation plate 21 is a metal with high toughness and high wear resistance.

[0038] Going further:

[0039] In an optional embodiment, the input gear 24 is composed of two gears, one large and one small, and the circles where the two gears are located are concentric circles.

[0040] In this embodiment: through the combination of two gears of different sizes, the momentum can be increased through the large gear when meshing occurs between the rack 22 and the small gear arranged on the surface of the input gear 24, and then when meshing occurs between the input gear 24 and the output gear 26, the coil 27 can be driven to pull the pull rope 28 to perform long-distance power transmission.

[0041] Going further:

[0042] In an optional embodiment, the cleaning grid 212 is shaped as a cuboid with rectangular through grooves equidistantly formed on the surface.

[0043] In this embodiment, the equally spaced grooves enable the driver to effectively observe the information on the warning sign 210 , and at the same time, the warning sign 210 can be effectively cleaned by cleaning the grille formed by the surface of the grille 212 .

[0044] Going further:

[0045] In an optional embodiment, a reset component 3 is further included on one side of the speed bump body 1, the reset component 3 includes a spring 31 and a connecting block 32, one end of the spring 31 is fixedly connected to the surface of the cleaning grille 212, and the other end of the spring 31 is fixedly connected to the connecting block 32 fixedly mounted on the surface of the warning sign 210, and the surface of the connecting block 32 is also fixedly connected to the end of the stabilizer bar 211.

[0046] In this embodiment: after the cleaning grille 212 falls, the connecting block 32 will compress the spring 31 arranged between the cleaning grille 212. At this time, the spring 31 is in a compressed state. When a vehicle passes over the speed bump body 1, the deformable plate 21 rebounds and drives the rack 22 to pull back. At this time, the pull rope 28 will be relaxed for a moment, and then the contracted spring 31 will rebound and push the cleaning grille 212 to reset and pass over the surface of the warning sign 210 again, so that the cleaning grille 212 can smoothly perform reciprocating cleaning work on the surface of the warning sign 210.

[0047] Going further:

[0048] In an optional embodiment, the spring 31 and the connecting block 32 are symmetrically arranged on both sides of the surface of the warning sign 210 .

[0049] In this embodiment, the symmetrically arranged springs 31 and connecting blocks 32 can provide a more stable source of force for the resetting work of the cleaning grid 212, making the resetting work more stable.

[0050] The working principle and use process of the utility model are as follows: when a vehicle passes over the speed bump body 1, the wheel will press over the deformation plate 21 and squeeze the deformation plate 21 from an arc-shaped state to a flat state. At this time, the deformation plate 21 will push the rack 22 and the speed bump body 1 to slide through the deformed plane. At this time, the rack 22 will mesh with the small gear set on the surface of the input gear 24, and the stabilizing bar A23 and the input gear 24 are in a rotating state. The stabilizing bar A23 can ensure the stability of the rotation of the input gear 24. At this time, the input gear 24 will rotate as a whole, and the large gear set on the surface of the input gear 24 will mesh with the output gear 26 and drive the output gear 26 and the coil 27 and the stabilizing bar B25 to rotate. When the coil 27 rotates, the coil 27 will pull the pull rope 28 wrapped around its surface. At this time, the pull rope 28 will pull the cleaning grille 212 set on the surface of the warning sign 210 along the inside of the warning rod 29, and enable the cleaning grille 212 to move from the surface of the warning sign 210 to the warning rod 29. , and compresses the spring 31 arranged below it. At this time, the stabilizing bar 211 arranged parallel to the surface of the warning sign 210 will slide between the cleaning grille 212 and keep the cleaning grille 212 stable. Then the wheel rolls over the surface of the deformable plate 21, and the deformable plate 21 returns to its original state. At this time, the coil 27 will also rotate in the opposite direction, and the pull rope 28 will be in a relaxed state when the coil 27 rotates in the opposite direction. Then the spring 31 will rebound and push the cleaning grille 212 back to its original position. When the cleaning grille 212 falls, the connecting block 32 will compress the spring 31 arranged between the cleaning grille 212. At this time, the spring 31 is in a compressed state. When the vehicle above the speed bump body 1 passes, the deformable plate 21 rebounds and drives the rack 22 to pull back. At this time, the pull rope 28 will be in a relaxed state for a moment, and then the contracted spring 31 will rebound and push the cleaning grille 212 to reset and pass over the surface of the warning sign 210 again, so that the cleaning grille 212 can smoothly perform reciprocating cleaning work on the surface of the warning sign 210.

[0051] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention.
