Description

Technical Field

[0001] This utility model belongs to the field of tunnel wall cleaning technology, specifically relating to high-pressure automatic cleaning equipment for tunnel walls. Background Technology

[0002] With the rapid development of urban transportation networks, tunnels, as vital transportation facilities connecting various urban areas, play a crucial role in ensuring traffic safety, extending tunnel lifespan, and enhancing the city's image through the cleanliness and maintenance of their internal environment. As traffic volume increases, exhaust fumes and dust from vehicles adhere to tunnel walls, leading to increasingly serious wall pollution and posing significant safety hazards for passage through tunnels. Currently, to improve the convenience and efficiency of tunnel cleaning, several cleaning devices have emerged, such as tunnel cleaning trucks. There are two main types of tunnel cleaning trucks: roller brush tunnel cleaning trucks and high-pressure water tunnel cleaning trucks. Since the tunnel wall is a closed space, all aspects of the curved inner wall must be cleaned. While existing cleaning devices can automatically clean the tunnel walls, they struggle to thoroughly clean corners and arched surfaces, requiring manual cleaning in these areas, which is time-consuming, labor-intensive, and inefficient. Utility Model Content

[0003] In view of the problems existing in the prior art, this utility model provides a high-pressure automatic cleaning equipment for tunnel walls, which can perform fast and effective cleaning and maintenance work on tunnel sidewalls.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Please see Figure 1-4This utility model provides a technical solution for a high-pressure automatic cleaning device for tunnel walls: Example

[0018] according to Figure 1 and Figure 2 As shown, the device includes a vehicle body 1, on which a water tank 2 and an equipment controller 3 are mounted. The equipment controller 3 is used to control the overall operation of the equipment, and a high-pressure water pump is installed inside the equipment controller 3. The high-pressure water pump is connected to the water tank 2 through a water suction pipe and can extract water from the water tank 2. The water tank is provided with an inlet and an outlet for replenishing water into the water tank or discharging excess water. A hinge seat 4 is provided on the upper surface of the water tank 2. The device also includes a water spray assembly 5 composed of a swing arm. The bottom end of the swing arm is hinged to the hinge seat 4, and a nozzle 54 is fixed at the top end. A water flow channel is opened in the swing arm and communicates with the nozzle 54. The output end of the water pump is connected to the water flow channel in the swing arm through a water pipe 6 to supply water to the nozzle 54 through the water pipe 6 and the water flow channel, so that the nozzle 54 can spray water at high pressure.

[0019] The automatic cleaning equipment also includes a drive mechanism 7 for controlling the reciprocating oscillation of the water spray assembly 5. The specific structure of the drive mechanism 7 is as follows: Figure 3 As shown, the system includes a motor 71 mounted above the water tank 2 via a motor bracket. A turntable 72 is fixedly mounted on the output end of the motor 71 via a rotating shaft. An eccentric column 73 is fixed to the front side of the turntable 72. A drive rod 74 is rotatably mounted on the eccentric column 73. A guide groove 76 is provided on the swing rod along the extension direction of the rod body. A guide block 75 is slidably mounted in the guide groove 76. The outer end of the eccentric column 73 is hinged to the guide block 75. The motor 71 drives the turntable 72 to rotate. Through the cooperation of the eccentric column 73 and the drive rod 74, the drive rod 74 can pull the swing rod to swing back and forth left and right. In turn, the swing rod drives the nozzle 54 at the top to swing back and forth left and right, so that the nozzle 54 sprays water with an arc surface to perform high-pressure water spray cleaning on the arc-shaped inner wall of the tunnel top.

[0020] In practical use, the high-pressure automatic tunnel wall cleaning equipment of this utility model is started and moves forward in the tunnel. At the same time, the internal high-pressure water pump is controlled by the equipment controller 3 to operate, drawing water from the water tank 2 and sending it into the nozzle 54 through the water pipe 6 and the water flow channel in the swing arm. The water is sprayed upward at high pressure through the nozzle 54, and the high-pressure water flow can directly clean the tunnel arc wall. At the same time, the motor 71 can be started, and the motor 71 controls the turntable 72 to rotate. While the turntable 72 is rotating, the eccentric column 73 pulls the drive rod 74 to swing back and forth. In turn, the pulling effect of the drive rod 74 drives the swing arm to swing left and right, so that the nozzle 54 swings and sprays water, realizing the automatic cleaning of the tunnel arc wall. Example

[0021] Based on Example 1, the similarities between this example and Example 1 will not be repeated here. The differences are as follows: Figure 3 and Figure 4 As shown, the water spray assembly 5 consists of multiple swing arms, which form a fan-shaped spray beam. Adjacent swing arms are connected by adjusting components. Here, two swing arms are used as an example. Figure 3 As shown, the device includes a first swing arm 51 and a second swing arm 52. A nozzle 54 is fixed to the top of both swing arms 51 and 52. The bottom ends of both swing arms 51 and 52 are hinged to a hinge seat 4. A drive rod 74 is connected to the first swing arm 51. A clearance groove is provided at the bottom end of the first swing arm 51. The diameter of the bottom end of the second swing arm 52 is smaller than the inner diameter of the clearance groove, allowing the first swing arm 51 and the second swing arm 52 to be hinged at the same position on the hinge seat 4 without interfering with each other. The first swing arm 51 and the second swing arm 52 are connected by an adjusting member 53, which can adjust the included angle between the first swing arm 51 and the second swing arm 52, thereby adjusting the spray range of the nozzles 54 at the top of the first swing arm 51 and the second swing arm 52.

[0022] The specific structure of the adjusting component 53 is as follows: Figure 4 As shown, the device includes a solenoid 532 and screw rods 531 and 533 threadedly fitted at both ends of the solenoid 532. The screw rods 531 and 533 have opposite thread directions, so that when the solenoid 532 is rotated, the screw rods at both ends can move in opposite directions. A sliding groove 534 is provided on the side wall of the rocker rods 51 and 52 along the extension direction of the rod body. A slider 535 is slidably fitted in the sliding groove 534. The outer ends of the screw rods 531 and 533 are hinged to the slider 535.

[0023] In practical use, when it is necessary to adjust the spray range of the water spray component 5, the screw tube 532 is manually rotated. Through the threaded engagement of the screw tube 532 and the screw rods 531 and 533, the screw rods 531 and 533 are controlled to move in opposite directions, thereby causing the swing rods 51 and 52 to move closer or further apart. The angle between the swing rods 51 and 52 is adjusted, thereby adjusting the spray range of the two nozzles 54. The nozzle 54 at the top of the swing rod 51 is mainly responsible for cleaning the tunnel top wall, and the nozzle 54 at the top of the swing rod 52 is mainly responsible for cleaning the tunnel side wall. After the tunnel top and one side wall are cleaned, the equipment can be reversed to clean the other side wall, further improving the cleaning effect of the tunnel wall.

[0024] The above description is only a preferred embodiment of the present utility model and does not limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
