Description

Technical Field

[0001] This invention relates to the field of tunnel engineering technology, specifically to a high-speed tunnel lighting cleaning device and cleaning method. Background Technology

[0002] Currently, with the rapid development of my country's transportation network, the mileage of expressways is gradually increasing, and the number and length of tunnels are also gradually increasing. Due to the enclosed internal environment and poor ventilation of expressway tunnels (especially long tunnels), exhaust fumes from vehicles and dust generated during vehicle operation are difficult to disperse in a timely manner. These fumes tend to adhere to the inner wall surface of the tunnel and the surface of the tunnel lighting equipment, causing the luminous intensity of the lighting equipment to decay rapidly, thus affecting the lighting inside the tunnel and creating serious traffic safety hazards.

[0003] Currently, the main method for dealing with oil stains (mainly generated by vehicle exhaust) and dust (mainly generated by dust generated inside the tunnel) on the surface of lighting equipment in highway tunnels is to have cleaning personnel manually clean the equipment while engineering vehicles travel inside the tunnel. This method has the following problems: First, the high density of streetlights in tunnels leads to low efficiency and high implementation costs for manual work, resulting in a significant waste of labor resources. Second, oil stains on the surface of tunnel streetlights are difficult to clean thoroughly, resulting in poor manual cleaning effects and inconsistent cleaning. Third, during the cleaning process, engineering vehicles need to occupy the road, affecting traffic conditions inside the highway tunnel and easily causing traffic congestion or even traffic accidents. Fourth, the poor lighting inside the tunnel affects judgment during the manual cleaning process, resulting in long cleaning times, poor cleaning effects, and the potential for cleaning dead spots. Summary of the Invention

[0004] To address the problems existing in the prior art, the present invention aims to provide a high-speed tunnel lighting cleaning device. This cleaning device can automatically clean the surface of lighting equipment in high-speed tunnels and has the advantages of compact structure, high operating efficiency, and good cleaning effect. Moreover, this cleaning device does not occupy the driving lane, effectively avoiding traffic congestion or traffic accident hazards caused by engineering vehicles occupying the lane during the cleaning process.

[0013] For further optimization, the cleaning assembly includes a rotating spindle, rocker arms, a roller, a connecting beam, a spring shaft, and connecting rods. The rotating spindle is mounted on the upper side of the "7"-shaped bracket, and both ends of the rotating spindle are connected to the outer walls of the two output shafts away from the external gears via rocker arms. The roller is fixedly sleeved on the outer wall of the rotating spindle between the two rocker arms, and cleaning bristles are evenly distributed on the outer wall of the roller. The two rocker arms are connected to each other and located below the roller via a connecting beam, thereby ensuring the stability between the two rocker arms. A spring shaft is mounted on the side of the connecting beam near the drive wheel mechanism and corresponding to the spring core. The spring shaft and the spring core are connected by a tension spring. Connecting rods are mounted on the opposite sides of the two rocker arms on the connecting beam.

[0017] A method for cleaning high-speed tunnel lighting lamps, characterized in that: firstly, a moving track is pre-set below the high-speed tunnel lighting equipment; then, a cleaning device is placed on the moving track, with the driving wheel mechanism and the driven wheel mechanism respectively contacting the moving track; then, the drive assembly is started, so that it controls the operation of the moving frame and the cleaning assembly through the differential transmission assembly and the belt transmission assembly respectively, to clean the lighting equipment.

[0018] The present invention has the following technical effects:

[0019] This application drives a differential transmission assembly to rotate via a drive component. Utilizing the cooperation between the differential transmission assembly and the first and second arc-shaped friction plates, different rotational speeds are achieved on the two output shafts of the differential transmission assembly. This allows for automatic switching between two states: street light cleaning and rapid movement, based on the distribution of the lighting equipment. Firstly, this ensures thorough and effective cleaning of the lighting equipment. Secondly, it enables rapid movement of the equipment during the cleaning process, saving movement time and improving overall cleaning efficiency. Through the interaction between the cleaning component and the lighting equipment, the forward speed of both components is automatically adjusted. During the cleaning process, the forward speed of the equipment slows down, thereby improving the cleaning effect, avoiding cleaning blind spots, and effectively cleaning and scraping away oil, dust, and other contaminants from the surface of the lighting equipment, while ensuring consistent cleaning across all lighting equipment surfaces.

[0020] This application utilizes a pre-installed mobile track to clean lighting equipment inside tunnels, effectively avoiding road congestion and traffic accidents caused by cleaning that obstructs the road. Furthermore, the cleaning equipment is compact, simple, and small in size, requiring minimal space and facilitating easy movement, placement, and maintenance. It automatically cleans the lighting equipment inside tunnels, effectively saving manpower and resources, avoiding the safety hazards associated with manual cleaning, while also providing high cleaning efficiency and thoroughness, avoiding human interference during the cleaning process and preventing cleaning dead spots.

The drive assembly 30 includes a motor 31 and a drive gear 32.

[0042] A method for cleaning high-speed tunnel lighting lamps, characterized in that:

[0043] First, the moving track 100 is pre-installed below the high-speed tunnel lighting equipment 300 via the hoisting bracket 101;

[0044] Then, the motor 31 is started and rotates, which drives the external gear 41 to rotate via the drive gear 32; when the outer wall of the roller 53 of the cleaning component 50 contacts the bottom surface of the lighting device 300, relative movement occurs between the roller 53 and the lighting device 300, resulting in a mutual squeezing force (a foam buffer layer can be provided on the outer wall of the roller 53 for cushioning), that is, the lighting device 300 applies a force to the roller 53, causing the roller 53 to rotate around the output shaft 44 via the rocker arm 52. Figure 6 As shown, rotating clockwise causes the first arc-shaped friction plate 26 and the second arc-shaped friction plate 27 to rotate around the fixed pin 25 via two connecting rods 56. At this time, the first arc-shaped friction plate 26 contacts the corresponding friction wheel 48, and the second arc-shaped friction plate 27 disengages from the corresponding friction wheel 48 (causing the output shaft 44 corresponding to the first arc-shaped friction plate 26, i.e., ...). Figure 2 The lower side shown Figure 10 The left-side output shaft 44 is shown to have restricted rotation; the output shaft 44 corresponding to the second arc-shaped friction plate 27, i.e. Figure 2 The upper side shown Figure 10The right-side output shaft 44 rotates unrestricted, and the tension spring 550 is extended. The planetary gear shaft 46 follows the external gear 41 and rotates around the central axis of the external gear 41. Since the planetary gears 47 mesh with the output gears 45 on both sides, the two planetary gears 47 rotate around... Figure 10 The output gear 45 on the left side of the diagram rotates and drives... Figure 10 The output gear 45 on the right side of the diagram rotates with the output shaft 44. Figure 10 The output shaft 44 on the left side (shown as not rotating) Figure 10 The output shaft 44 on the right side of the diagram drives the second pulley 62 and the fourth pulley 64 to rotate through the sixth pulley 66 and the eighth pulley 68, respectively. By utilizing the transmission ratio between the second pulley 62, the fourth pulley 64 and the sixth pulley 66, the eighth pulley 68, the drive wheel mechanism 13 rotates slowly while the rotating spindle 51 and the drum 53 rotate quickly. That is, the cleaning equipment moves forward slowly while the drum 53 rotates quickly for cleaning, which increases the time in the cleaning process and enhances the cleaning effect.

[0045] When the outer wall of the roller 53 of the cleaning assembly 50 is disengaged from the lighting device 300, that is, when the cleaning device 200 is not located below the lighting device 300, the roller 53 is propelled by the elastic force of the tension spring 550 to rotate around the output shaft 44 via the rocker arm 52. Figure 6 The counterclockwise rotation, as shown, causes the first arc-shaped friction plate 26 to disengage from the corresponding friction wheel 48, and the second arc-shaped friction plate 27 to contact the corresponding friction wheel 48 (causing the output shaft 44 corresponding to the first arc-shaped friction plate 26, i.e., Figure 2 The lower side shown Figure 10 The output shaft 44 on the left side is shown to rotate without restriction; the output shaft 44 corresponding to the second arc-shaped friction plate 27, i.e. Figure 2 The upper side shown Figure 10 (As shown, the right-side output shaft 44 is restricted in its rotation). At this time, the planetary gear shaft 46 continues to rotate around the central axis of the external gear 41, causing the two planetary gears 47 to rotate around... Figure 10 The output gear 45 on the right side of the diagram rotates and drives... Figure 10 The output gear 45 on the left side of the diagram rotates with the output shaft 44, that is... Figure 10 The output shaft 44 on the left side of the diagram rotates ( Figure 10 (The output shaft 44 on the right side is not rotating), thereby driving the first pulley 61 and the third pulley 63 to rotate through the fifth pulley 65 and the seventh pulley 67 respectively. By utilizing the transmission ratio between the first pulley 61, the third pulley 63 and the fifth pulley 65 and the seventh pulley 67, the drive wheel mechanism 13 rotates quickly, while the rotating spindle 51 and the drum 53 rotate slowly. That is, the cleaning equipment moves forward quickly, and the drum 53 rotates slowly for cleaning, so that the cleaning device 200 can move quickly to the lower cleaning point and shorten the intermediate movement time.

[0046] Furthermore, when the drum 53 and hub shaft 121 rotate, their power is supplied only by a single output shaft 44. Figure 10 The output shaft 44 at the right or left end is provided, while the output shaft 44 at the other end stops rotating under the action of the friction plate (first arc-shaped friction plate 26 or second arc-shaped friction plate 27); through the ratchet mechanism, the pulley corresponding to the output shaft 44 at the non-rotating end can rotate in the opposite direction with the belt drive, while the output shaft 44 remains stationary, that is, the power transmission will not be transmitted to the restricted output shaft 44 side, and there will be no problem of reverse power jamming the equipment.

[0047] Example 2:

[0048] As a further optimization of the solution in this application, based on the solution in Embodiment 1, in order to further ensure the cleaning effect, the front end of the chassis 11 (i.e. Figure 7 A spraying device is installed at the left end (as shown). The spraying device includes an upward-sloping nozzle and a liquid storage tank. The nozzle is connected to the liquid storage tank and a solenoid valve is installed on the nozzle.

[0049] An infrared sensor or a light intensity sensor can be installed at the front of the chassis 11. If an infrared sensor is installed, an infrared receiver must be installed on the lighting equipment 300. The cleaning device 200 is located under the lighting equipment 300 by the cooperation of the infrared sensor and the infrared receiver, or by the sensing of the light intensity sensor. Then, the solenoid valve is activated and water is sprayed onto the lighting equipment 300 through the nozzle.

[0050] Example 3:

[0051] As a further optimization of the present application, based on the embodiment 1, the moving track 100 is provided with a reversing mechanism at both ends of the tunnel (i.e., at the tunnel entrance and exit) for the cleaning device 200 to turn.

[0052] The reversing mechanism may include a lifting component and a steering component. The lifting component is used to lift the cleaning device 200 and remove it from the moving track 100, and the steering component is used to turn the lifted cleaning device 200 180° so that it can cycle through cleaning the lighting equipment 300. Both the lifting component and the steering component can be common devices in the art.
