Description

Technical Field

[0001] This utility model relates to the field of road warning sign technology, and in particular to a self-cleaning road warning sign. Background Technology

[0002] Road warning signs are essential roadside structures that provide drivers with road information. Over time, dust from the air, including road dust, will gradually adhere to the signs. When dust accumulates, it can make the warning information difficult to read, potentially affecting driving safety. Therefore, when road warning signs are heavily dusty and the information is difficult to read, they need to be wiped and cleaned promptly.

[0003] However, the height of warning signs on urban roads is generally between 2.0 and 2.5 meters, while the height of warning signs on highways is between 2.2 and 3.2 meters. The average height of workers is generally between 1.6 and 1.9 meters. The height of the warning signs makes it difficult for workers to clean them directly, requiring the use of special tools. This not only makes the operation complicated but may also affect the personal safety of workers. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a self-cleaning road warning sign. By setting up a nozzle with a long, plate-shaped cavity structure, and working with a water supply component inside the column, the warning sign can be sprayed and cleaned, making the warning information on the sign clearer and thus improving road safety. The inclined water collection tank below the warning sign prevents the cleaning water from dripping onto vehicles or pedestrians, and it can be smoothly drained to the ground through the drain pipe.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A self-cleaning road warning sign includes a post, a warning plate vertically mounted on the top of the post, a horizontal plate perpendicular to the warning plate located above the front side of the warning plate, and a nozzle mounted on the horizontal plate. The length of the nozzle is adapted to the length of the warning plate, and the nozzle has a long, plate-shaped hollow structure. The spray surface of the nozzle faces the warning plate and is evenly distributed with holes. A water supply assembly is located inside the post, and the outlet end of the water supply assembly is connected to the nozzle. A water collection trough is located at the bottom of the warning plate, and the bottom of the water collection trough is drained away through a drain pipe.

[0007] As a further implementation, the column is mounted on the ground via a base.

[0008] As a further implementation, the drain pipe is vertically installed inside the column, with the top end of the drain pipe extending to the outside of the column to connect to the water collection tank near one end of the column, and the bottom end extending to the outside of the bottom of the column.

[0009] As a further implementation, the water supply assembly includes a water tank and a water pump located inside the column; the water pump inlet is connected to the water tank via a first conduit, and the water outlet is connected to the nozzle inlet via a second conduit.

[0010] As a further implementation, a power supply is also included, which is connected to the water pump to provide power to the pump.

[0011] As a further implementation, the top of the warning board is connected to the horizontal plate via a connecting plate, the connecting plate and the warning board are in the same plane, and the length of the connecting plate is the same as that of the warning board.

[0012] As a further implementation, the nozzle has a triangular cross-section and an arc-shaped spray surface, so that the spray water can cover the warning board.

[0013] As a further implementation, the water collection trough is U-shaped, with its top end connected to the bottom edge of the warning board, and the end of the water collection trough furthest from the column is higher than the end of the water collection trough closest to the column.

[0014] As a further implementation, the column is hollow inside, and a water tank is installed inside the column via a support plate, with the height of the water tank lower than the middle position of the column.

[0015] As a further implementation, a cover plate is hinged to the column, the cover plate can be opened, and the position of the cover plate corresponds to the position of the water tank.

[0016] The beneficial effects of this utility model are as follows:

[0017] This invention utilizes a spray nozzle with a long, hollow, plate-like structure, in conjunction with a water supply component within the column, to spray and clean warning signs, making the warning information on the signs clearer and thus improving road safety. The spray nozzle is mounted on a horizontal plate, which also acts as a baffle to reduce dust on the warning signs and provides mounting points for the nozzle. The warning signs are connected to the horizontal plate via a connecting plate with a set width to ensure that the horizontal plate does not obstruct the information on the warning signs. The inclined water collection tank below the warning signs prevents cleaning water from dripping onto vehicles or pedestrians, and allows it to drain smoothly to the ground through a drain pipe. This invention eliminates the need for workers to perform high-altitude operations; simply turning on the water pump button avoids the safety hazards associated with workers performing such operations.

[0024] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0025] Example 1

[0026] In a typical embodiment of this utility model, refer to Figures 1-3 As shown, a self-cleaning road warning sign includes a post 8, a warning plate 1 vertically mounted on the top of the post 8, a horizontal plate 12 perpendicular to the front of the warning plate 1, and a nozzle 2 mounted on the horizontal plate 12. The length of the nozzle 2 is adapted to the length of the warning plate 1, and the nozzle 2 has a long, plate-shaped hollow structure. The spray surface 21 of the nozzle 2 faces the warning plate 1 and is evenly distributed with holes. A water supply assembly is provided inside the post 8, and the water outlet of the water supply assembly is connected to the nozzle 2. A water collection tank 3 is provided at the bottom of the warning plate 1, and the bottom of the water collection tank 3 is drained away through a drain pipe 10.

[0027] like Figure 1 As shown, the column 8 is installed on the ground via the base 9, and the warning plate 1 is horizontally positioned at the top of the column 8, and the warning plate 1 is perpendicular to the column 8, forming an L-shaped structure.

[0028] like Figure 2As shown, a horizontal plate 12 perpendicular to the front upper side of the warning plate 1 is provided. The top of the warning plate 1 is connected to the horizontal plate 12 via a connecting plate 13. The connecting plate 13 and the warning plate 1 are in the same plane. The connecting plate 13, the warning plate 1, and the horizontal plate 12 have the same length, forming an L-shaped plate structure with the connecting plate 13 and the warning plate 1. The thickness of the connecting plate 13 is less than the thickness of the warning plate 1. The connecting plate 13 has a set width, which allows the horizontal plate 12 to be higher than the warning plate 1 by a set distance. The horizontal plate 12 acts as a baffle, reducing dust adhering to the warning plate 1 and lessening the cleaning burden on the warning plate 1.

[0029] like Figure 2 As shown, a nozzle 2 is fixed to the front edge of the horizontal plate 12, and the length of the nozzle 2 is adapted to the length of both the horizontal plate 12 and the warning plate 1. The nozzle 2 has a long, plate-shaped hollow structure, and its spray surface 21 faces the warning plate 1 and is evenly distributed with holes for spraying water. Specifically, the nozzle 2 has a triangular cross-section, but the spray surface 21 is not arranged in a flat plate, but rather in an arc shape, so that the sprayed water can cover the warning plate 1 after spraying out of the holes, ensuring that all positions on the warning plate 1 are sprayed with water.

[0030] The width of the horizontal plate 12 is determined according to the size of the warning plate 1 to ensure that the water sprayed from the nozzle 2 can be sprayed onto the warning plate 1.

[0031] To prevent cleaning water droplets from falling on vehicles or pedestrians after spraying, a water collection trough 3 is provided at the bottom of the warning board 1. The water collection trough is U-shaped, with its main body located on the front side of the warning board 1, and its top end connected to the bottom edge of the warning board 1. The length of the water collection trough 3 is slightly longer than the length of the warning board 1, such as... Figure 1 As shown, the left end of the warning board 1 is located between the left end of the water collection tank 3 and the column 8, ensuring that all the cleaning water can fall into the water collection tank 3.

[0032] like Figure 1 As shown, the end of the water collection tank 3 furthest from the column is higher than the end of the water collection tank 3 closest to the column 8, that is, the left end is higher than the right end, thus achieving an inclined setting. The clean water falling into the water collection tank 3 can move to the right along the water collection tank 3 to the column.

[0033] like Figure 1 As shown, in order to drain the clean water, the drain pipe 10 is vertically installed inside the column 8. The top end of the drain pipe 10 extends to the outside of the column 8 and connects to the water collection tank 3 near one end of the column. The bottom end extends to the outside of the bottom of the column 9. The water in the water collection tank 3 is drained to the ground through the drain pipe 10.

[0034] like Figure 1As shown, the water supply assembly includes a water tank 6 and a water pump 5 housed inside the column 8. The inlet of the water pump 5 is connected to the water tank 6 via a first conduit 11, and the outlet is connected to the inlet at the right end of the nozzle 2 via a second conduit 4. A power supply 7 is also fixedly installed inside the column, connected to the water pump 5 to supply power. The power supply is either a battery or the power grid, and the configuration of the power supply 7 is existing technology.

[0035] In an optional example, the column 8 is hollow inside, and a water tank 6 is installed inside the column 8 via a support plate. The height of the water tank 6 is lower than the middle position of the column 8 to facilitate the addition of water to the water tank 6.

[0036] Furthermore, the column 8 has an opening with a cover hinged to it. The cover can be opened, and its position corresponds to that of the water tank 6. When water needs to be added, the cover is opened, and cleaning water is added to the water tank 6. The structure of the cover is not limited, as long as it can be opened. In this embodiment, by setting up the nozzle 2, water tank 6, and water pump 5, the water pump can be turned on to spray and self-clean the road warning sign when there is a lot of dust on its surface, removing surface dust and making the warning information on the warning sign 1 clearer, thereby improving road safety. It eliminates the need for workers to perform high-altitude operations; simply activating the water pump button avoids the safety hazards associated with workers working at heights.

[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
