Description

Technical Field

[0001] This utility model relates to the field of highway guardrail maintenance technology, specifically to an automatic cleaning device for highway guardrails. Background Technology

[0002] Corrugated guardrails are a core anti-collision facility widely used on Chinese highways. Their main body consists of continuous corrugated steel plates (W-shaped cross-section), posts, anti-collision blocks, and connecting bolts. The corrugated steel plates efficiently absorb collision energy through deformation, reducing vehicle impact. Meanwhile, the posts (typically spaced 4 meters apart) are firmly connected to the foundation, ensuring guidance. The surface is galvanized or powder-coated, providing a corrosion resistance lifespan of 15-25 years. Silver, green, and other colors combine warning effectiveness with aesthetic appeal. Reflective markers are added to the top of the guardrail, significantly improving nighttime visibility. Suitable for median strips and roadside areas, these guardrails balance protective strength and economy, making them a key technological equipment for improving passive driving safety.

[0003] Over time, corrugated guardrails accumulate dust. Current highway guardrail cleaning methods mainly rely on manual operation, which is inefficient and requires workers to work near traffic, posing traffic safety hazards. Most equipment requires manual adjustment, lacks intelligence and automation, and is also bulky, requiring cleaning trucks for water spraying, resulting in high water consumption.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0023] Please see Figure 1-4 The present invention provides an automatic cleaning device for highway guardrails, including a support frame 1, a cleaning device located in the middle of the support frame 1, a driving device 2, a clamping device 202, and a solar energy device located at the top of the support frame 1.

[0024] The support frame 1 includes a frame-shaped bracket consisting of a vertical fixing plate 101, a solar panel fixing frame 103 horizontally connected above and below the vertical fixing plate 101, and a bottom fixing plate 102. Two wavy brush plates 104 and multiple water spray pipes 301 are connected to the inner side plate of the vertical fixing plate 101. The edges of the bottom fixing plate 102 and the solar panel fixing frame 103 are respectively fixed with a pair of symmetrical clamping devices 202 through slots.

[0025] The cleaning device includes two telescopic rods 106 mounted on the inner side plate of a vertical fixing plate 101, which are distributed to the left and right. Two wavy brush plates 104 are connected to the two telescopic rods 106, and sponge pads are installed on the front end face of the two wavy brush plates 104. Four evenly distributed water spray pipes 301 are installed on the left and right sides of the wavy brush plates 104 via water pipes to a straight plate 105. A high-pressure atomizing nozzle 3011 is installed at the front end of the water spray pipes 301. The water spray pipes 301 pass through the vertical fixing plate 101, and the other end of the water spray pipes 301 is connected to a water pump 302. The water pump 302 is equipped with a water pump connected to the water tank pipe 3. The water pump is electrically connected to the solar energy device.

[0026] A high-pressure atomizing nozzle 3011 is installed at the front end of the water spray pipe 301, which decomposes the water flow into micron-sized droplets. The impact force and coverage area of ​​the atomized water flow are used to clean the surface of the guardrail, which is suitable for cleaning light pollution such as dust and stains.

[0027] During installation, the water spray pipe 301 is inserted into the corresponding mounting holes of the vertical fixing plate 101 and the water pipe fixing plate 105. The pipe is positioned by the synergistic clamping action of the two, which effectively enhances the structural stability of the water spray pipe 301 and achieves the technical effect of rapid positioning and installation.

[0028] The two wavy brush plates 104 are similar in shape to the wavy guardrails of highways. Since the specifications and dimensions of highway guardrails are basically fixed, the angle and length of the wavy brush plates can be customized according to the guardrail specifications to achieve a higher degree of fit. The wavy brush plates 104 are tightly fitted to the guardrail by the telescopic rod 106, thereby achieving full contact between the surface of the sponge pad and the guardrail, realizing brushing and washing simultaneously, and improving the cleaning effect.

[0029] The water spray pipe 301 sprays water onto the surface of the guardrail through the high-pressure atomizing nozzle 3011. Compared with traditional high-pressure water jets, the atomized water flow can reduce water consumption by 30%-50%, achieving the effect of saving water.

[0030] like Figure 1 Combination Figure 2 As shown, the solar energy device includes a solar panel mounting bracket 103 located on top of a support frame 1. A support rod 107 is mounted on the upper end of the solar panel mounting bracket 103, and a top plate 108 is fixed to the upper end of the support rod 107. A solar panel 109 is mounted on the upper surface of the top plate 108, and a battery 110 is mounted on the lower surface of the top plate 108. A motor frame 111 is fixed to the front end of the solar panel mounting bracket 103, and a drive motor 201 is connected to the motor frame 111 via a slot. The drive motor 201 and the solar panel 109 are electrically connected.

[0031] The upper and lower clamping devices 202 are detachably connected to the solar panel mounting bracket 103 and the bottom fixing plate 102 via slots. In use, the upper and lower clamping devices 202 are fixed to the entire device via the slots of the solar panel mounting bracket 103 and the bottom fixing plate 102, which facilitates the disassembly and installation of the clamping devices 202 by the staff.

[0032] When the device is used under sunlight, the solar panel 109 can convert light energy into electrical energy, which is then stored in the battery 110 to provide power for the operation of the equipment and achieve energy-saving effect.

[0033] A drive motor 201, which is fixed to the edge of the solar panel mounting bracket 103 via a motor bracket 111, is connected to a clamping device 202. The motor bracket 111 and the drive motor 201 are detachably connected via a slot. In use, the drive motor 201 is mounted on the lower part of the solar panel mounting bracket 103 via the motor bracket 111, facilitating the installation and removal of the drive motor 201 by personnel.

[0034] like Figure 3 As shown, a drive shaft 2011 and a drive wheel 2012 are connected to the drive motor 201. The drive motor 201 drives the drive wheel 2012 to rotate through the drive shaft 2011. The drive wheel 2012 is connected to the pulley 207 through the belt 208. The pulley 207 is connected to the clamping device 202 through the transmission shaft 206. The clamping device 202 is connected to the solar panel fixing plate 103 through the slot.

[0035] like Figure 4 As shown, the clamping device 202 includes a frame plate. The frame plate is connected to two upper and lower roller fixing frames 205 via spring rods 204 fixed to the inner side of the plate. Two rows of rollers 203 are connected to the upper and lower roller fixing frames 205, and the two rows of rollers 203 are symmetrically installed vertically. A drive shaft 206 connects to one of the rollers 203 to rotate, and the adjacent rollers 203 rotate synchronously, driving the clamping device 202 to move horizontally along the highway guardrail with the trolley.

[0036] In use, the device is first connected to the lower movable water tank via the pump pipe 302. Then, the clamping device 202 is fixed to the solar panel mounting bracket 103 and the bottom mounting plate 102. The spring rod 204 and roller mounting bracket 205 in the clamping device 202 clamp the rollers 203 of the device to the upper and lower ends of the guardrail. Simultaneously, the telescopic rod 106 pushes the wavy brush plate 104 towards the guardrail, ensuring that the sponge pad on the wavy brush plate 104 fits tightly against the guardrail. The drive motor 201 drives the drive shaft 2011. The rotation of the drive wheel 2012 causes the belt 208 to rotate, which in turn drives the pulley 207 to rotate. The pulley then drives the drive shaft 206, which in turn drives the roller 203. This allows the device to move automatically while clamping onto the guardrail. As the device moves along the guardrail, the speed of the moving water tank below remains consistent with its movement. The guardrail is rinsed by the front spray pipe 301, then wiped by the sponge pads on the scrubbing plate, and finally rinsed by the rear spray pipe, achieving a fully automated wavy guardrail cleaning effect. When used under sunlight, the solar panel 109 converts solar energy into electrical energy, which is stored in the battery 110, providing power to the entire device. This device is small in size, requires no manual operation, and does not require a cleaning vehicle.

[0037] This utility model is not limited to the above embodiments. Based on the technical solutions disclosed in this utility model, those skilled in the art can make some substitutions and modifications to some of the technical features without creative labor, and these substitutions and modifications are all within the protection scope of this utility model.
