Description

Technical Field

[0001] This utility model relates to the field of road and bridge warning technology, and more specifically, to a road and bridge warning sign device. Background Technology

[0002] Road and bridge warning signs are an important component of traffic infrastructure, mainly including various signs, warning lights, delineators, and linear guides placed at bridgeheads and on the bridge deck. They are used to visually inform drivers in advance about the bridge's geometric features and road conditions, thereby guiding vehicles safely across the bridge area. They play an irreplaceable role in preventing traffic accidents and protecting the structural safety of bridges.

[0003] However, because the bridge is suspended in the air and has no obstructions, the air circulation on the bridge surface is strong, and moisture easily condenses on the surface of the signs. Especially in winter, the low temperature causes the condensed water vapor to freeze into ice and cover the signs, severely obscuring the graphic and text information of the signs. This leads to a sharp decrease in their reflectivity and visibility, greatly reducing their warning function and creating significant safety hazards.

[0004] To address the aforementioned issues, existing technologies include adding cleaning devices to warning signs to remove moisture and frost from the surface through mechanical scraping. However, the surface of warning signs in bridge environments not only retains moisture but also absorbs a large amount of dust and mud splashed by vehicles. When the wiper blades wipe water, they mix the water and dust, forming muddy water. When there is too much dust and the muddy water becomes too thick and accumulates on the wiper blades, the mud is spread onto the signs as the wiper blades move, making them even more blurry and dirty. Therefore, we propose a road and bridge warning sign device. Utility Model Content

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] Please see Figures 1-4 This utility model embodiment provides a technical solution: including a warning sign 1, the warning sign 1 including a mounting post and a sign body;

[0030] Drive component 2 is installed on the outer wall of warning sign 1;

[0031] In another embodiment of the present invention, preferably, the driving component 2 is a lead screw displacement component that can be driven by a forward and reverse rotating motor, including a threaded lead screw rotatably installed in the limiting housing, a lead screw sleeve connected to the external thread of the lead screw, and a wiper strip 502 fixed to the outer wall of the lead screw sleeve by a connecting rod.

[0032] The winding assembly 3 is installed on the outer wall of the warning sign 1 and has a transmission assembly 4 installed at its end. It includes a winding roller 301. Two sets of steel wire ropes 302 are symmetrically installed at both ends of the outer wall of the winding roller 301. The winding roller 301 is driven by the driving assembly 2 through the transmission assembly 4.

[0033] In another embodiment of this utility model, the transmission component 4 includes two pulleys coaxially fixed to the ends of the threaded screw of the take-up roller 301 and the drive component 2, respectively. The two pulleys are driven by a belt, and synchronous transmission is achieved between them. In actual use, the transmission ratio can be set according to actual usage requirements. When the drive component 2 drives the wiper strip 502 to move from one end of the outer wall of the warning sign 1 to the other end, the drive component 2 synchronously drives the take-up roller 301 to take up the strip. By taking up or unwinding the wire rope 302, the scraper strip 601 slides from one end of the back of the wiper strip 502 to the other end to achieve scraping.

[0034] The wiper strip 502 is set on the outer wall of the warning sign 1 and is triangular prism shaped. It can be driven to move horizontally by the drive component 2 and can be driven to move back and forth along the outside of the warning sign 1 to wipe away the water vapor and dust on the surface of the warning sign 1.

[0035] In another embodiment of the present invention, the power output end of the drive component 2 is connected to a wiper component 5. The wiper component 5 includes a top plate 501, and two wiper strips 502 are symmetrically installed at the bottom of the top plate 501. The two wiper strips 502 are respectively set on the front and back sides of the warning sign 1.

[0036] The scraper component 6 includes a slide bar 603, the length of which matches the corresponding side of the warning sign 1. The slide bar 603 is fixed to the end of the wire rope 302. A slide ring 602 is slidably connected to the outer wall of the slide bar 603. A scraper strip 601 is fixed to the outer wall of the slide ring 602. The scraper strip 601 can cooperate with the water scraper strip 502. The scraper strip 601 is slidably connected to the outer wall of the water scraper strip 502 through an embedded sliding component.

[0037] In another embodiment of this utility model, counterweights 604 are provided at both ends of the bottom of the slide bar 603 to ensure that the slide bar 603 rises and falls smoothly. At the same time, when the take-up roller 301 unwinds the wire rope 302, the counterweights 604 can cause the scraper 601 to fall downward under the action of gravity, scraping away the dirt on the back of the scraper 502 from top to bottom.

[0038] In another embodiment of this utility model, the scraper strip 601 is V-shaped and has a triangular cross-section.

[0039] Working principle: This embodiment provides a road and bridge warning sign device. When in use, it is powered by an external power source. The drive component 2 is turned on by an external switch. The drive component 2 is a screw displacement component that can be driven by a forward and reverse motor. It includes a screw rod that is rotated and installed in the limiting housing. The screw rod is connected to a screw sleeve by an external thread. The outer wall of the screw sleeve is fixed with a wiper strip 502 by a connecting rod.

[0040] When the forward and reverse motor rotates forward, it drives the wiper blade 502 to move horizontally from one end to the other along the surface of the warning sign 1. Since the wiper blade 502 is triangular prism-shaped, the two edges that are in contact with the surface of the warning sign 1 are convenient for wiping water, while the other edge is set between the two wiper edges, so that the water or dust wiped off slides out along the inclined surface and away from the warning sign 1 body, cleaning the water and dust on the surface of the warning sign 1 body.

[0041] Simultaneously, the drive component 2 drives the winding component 3 to move synchronously through the transmission component 4, winding or unwinding the wire rope 302. When winding the wire rope 302, the wire rope 302 pulls the slide bar 603, the slip ring 602 and the scraper bar 601 from the bottom to the top of the scraper bar 502, which can scrape off the mud attached to the scraper bar 502 during the scraping process, avoiding secondary pollution of the card surface, thereby achieving a better cleaning effect. The scraper bar 601 is slidably connected to the outer wall of the scraper bar 502 through the embedded sliding part, which is not easy to fall off. When the wire rope 302 pulls the slide bar 603, the slip ring 602 can slide along the outer wall of the slide bar 603, so that the scraper bar 601 only slides up and down along the back of the scraper bar 502 to scrape mud.

[0042] The scraper 601 is V-shaped and has a triangular cross-section, so that the scraped mud can easily move away from the scraper 502 along the inclined surface;

[0043] When the forward and reverse motor reverses, it drives the wiper blade 502 to move horizontally along the surface of the warning sign 1 from one end to the other end to reset. The same principle applies to the reciprocating motion. Both ends of the bottom of the slide bar 603 are equipped with counterweights 604 to ensure that the slide bar 603 rises and falls smoothly. At the same time, when the take-up roller 301 unwinds the wire rope 302, the counterweights 604 cause the wiper blade 601 to fall downward under the action of gravity, scraping away the dirt on the back of the wiper blade 502 from top to bottom and resetting it. (The drive component 2 is a commercially available product, and the forward and reverse motor of the drive component 2 is connected to an external power supply and an external switch.)

[0044] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
