[0002] As an important part of modern transportation network, the safety monitoring system inside the tunnel, especially the high-altitude camera, plays a crucial role in ensuring driving safety and monitoring the real-time conditions inside the tunnel. However, the special internal environment of the tunnel, the exhaust emissions, oil stains, dust and other pollutants brought by vehicle traffic can quickly accumulate on the camera lens, seriously affecting its imaging clarity and threatening the safety of tunnel operation.

[0003] Currently, the cleaning and maintenance of tunnel high-altitude cameras mainly relies on manual methods, that is, workers are sent to the camera position by lifting vehicles or aerial work platforms for manual wiping.

[0015] The beneficial effects of the present application are: 1. The present application controls the water pump to start, extracts the liquid in the water tank, and transports it to the cavity through the first corrugated pipe. When the liquid flowing into the cavity flows from bottom to top, the water flow will impact the impeller to rotate when flowing through the impeller, thereby driving the brush roller to roll synchronously, thereby cleaning the outer surface of the camera in contact. The water flow overflowing from the top end of the cavity will be directly sprayed through the spray nozzle, cooperating with the brush roller to clean the camera by spraying water. After cleaning, the support rod is controlled to reset, and during its descent, the bottom end of the support rod will squeeze the folding air bag, thereby causing the air flow in the air bag to be sprayed in an arc array through several air nozzles to the front camera, effectively improving the drying speed of the camera and reducing the probability of secondary adhesion of dust. It is convenient to use and improves the cleaning efficiency.

[0016] 2. The present application provides an arc surface of the operation plate with a combined cleaning component, which can focus on the target camera when spraying water or air. During cleaning, the collection module collects the camera shooting images, the images are preprocessed and analyzed by the image processing module, and then sent to the comparison module for comparison with the reference data. If the definition is qualified, a signal is transmitted to the control center to control the water pump to stop working and the motor b to start in reverse. Otherwise, the cleaning operation is continued, realizing the effect of cleaning the camera with intelligent definition detection.

[0017] 3. The present application controls the motor a to start, thereby driving the wire roller to rotate, and through the winding and unwinding of the connecting rope, the connecting plate realizes upward or downward sliding movement in the sliding groove, thereby adjusting the use height of the combined cleaning component according to the position of the aerial camera.

[0018] 4. The present application controls the motor b to drive, so that the motor b drives the support rod to move upward along the U-shaped seat under the meshing transmission of the gear, thereby adjusting the use height of the operation plate and the structure thereon according to the actual demand. When the support rod is passively moved upward, the folding air bag will be deformed as the distance between the support rod and the bottom end of the U-shaped seat is lengthened, thereby sucking external air into the air bag.

[0019] 5.The soft brush on the brush roller of the application abuts against the outer surface of the camera during passive rotation and is limited by the structure of the camera to adaptively adjust the fit, for example, when one soft brush abuts against the surface of the camera during rotation, it is affected by the convex-concave structure of the surface of the camera, such as a curved surface, and supports the rear movement, thereby synchronously sliding the frame-shaped plate in the horizontal or vertical port, so that the two elastic members in the frame-shaped plate are in compression and tension, respectively, so that the other soft brush on the frame-shaped plate opposite to the soft brush moves backward, thereby forming an adaptive fit and cleaning operation according to the actual structure of the camera, and improving the cleaning effect.

[0020] 6.Before the cleaning operation, the control top support rod is started to push the long plate to slide forward along the sliding rail, thereby stretching and unfolding the folding plate to collect the waste liquid during cleaning, so as to avoid the waste liquid from directly falling to the lower part, etc., the collected waste liquid will flow into the liquid collection filter box through the through port on the upper surface of the folding plate, and then be filtered by the filter plate and recycled into the water tank as waste water for repeated use, thereby effectively saving water resources.

The embodiments described below by referring to the drawings are exemplary only, for the purpose of explaining the present patent, and should not be understood as a limitation of the present patent.

[0028] As a supplement, the top end of the ladder 4 is rotatably connected with an I-shaped line roller 5, the outer wall of the line roller 5 is wound with a connecting rope 502, one end of the connecting rope 502 is tied to the top surface of the sliding block; One side outer wall of the ladder 4 is connected with a motor a 501 through a support plate, the output end of the motor a 501 is connected with one end of the line roller 5 through a shaft coupling; the motor a 501 is controlled to start, and then drives the line roller 5 to rotate, and through the winding and unwinding of the connecting rope 502, the connecting plate 16 realizes the upward or downward sliding movement in the sliding groove 401, so as to adjust the use height of the combined cleaning part according to the position of the high-altitude camera.

[0029] ​The lifting structure comprises a U-shaped seat 7 fixed on the top surface of the connecting plate 16, two support rods 701 respectively slidingly fitted on the inner walls of the two sides of the U-shaped seat 7, a rack 11 fixed on one side surface of one of the support rods 701 by bolts, a fixed plate 12 fixed on one side outer wall of the U-shaped seat 7 by bolts, a gear rotatably connected to one side inner wall of the fixed plate 12, a motor b1101 fixed on the bottom inner wall of the fixed plate 12 by bolts, wherein the outer wall of the gear is engaged with the outer wall of the rack 11, and the output end of the motor b1101 is connected to one end of the gear through a shaft coupling, and the bottom surface of the work plate 6 is fixed on the top ends of the two support rods 701 by bolts. In use, the motor b1101 is controlled to drive, so that the motor b1101 drives the support rod 701 to move upward along the U-shaped seat 7 under the engagement transmission of the gear, thereby adjusting the use height of the work plate 6 and the structure thereon according to actual needs.

[0030] In addition, the combined cleaning component comprises, from top to bottom, a gas spraying structure and a water spraying and rolling brush structure, the gas spraying structure comprises an array of gas spraying heads 19 fixed on one side surface of the work plate 6 by bolts, and a folding air bag 9 welded on the corresponding upper and lower side surfaces of the U-shaped seat 7 and the support rod 701, and the folding air bag 9 is connected in communication with the gas spraying heads 19 through a conduit. When the support rod 701 is passively moved upward, as the distance between the support rod 701 and the bottom end of the U-shaped seat 7 is lengthened, the folding air bag 9 is deformed to draw external air into it. When it is necessary to dry the cleaned camera, the support rod 701 is controlled to reset, and during the descending of the support rod 701, the bottom end of the support rod 701 presses the folding air bag 9, so that the airflow in the folding air bag 9 is sprayed in an arc array through the gas spraying heads 19 to the front camera, effectively improving the drying speed of the camera and reducing the probability of secondary adhesion of dust.

[0031] Further, the top outer wall of the base 1 is fixed with a water tank 2 by bolts, and the top surface of the water tank 2 is fixed with a water pump 8 for pumping liquid in the water tank 2 by bolts. The water spraying and rolling brush structure comprises a plurality of spray nozzles 14 fixed on one side surface of the work plate 6 by bolts, a brush roller 20 rotatably connected to the corresponding side surface of the work plate 6, a cavity opened in one side inner wall of the work plate 6, an impeller 18 rotatably connected to one side surface of the cavity, a first corrugated tube 801 for connecting the liquid inlet at the bottom end of the cavity and the output port of the water pump 8, wherein one end of the impeller 18 is connected to one end of the brush roller 20 through a connecting shaft, and the liquid outlet at the top end of the cavity is connected to the liquid inlet end of the spray nozzle 14 through a conduit. The water pump 8 is controlled to start, and the liquid in the water tank 2 is pumped out and transported into the cavity through the first corrugated pipe 801. When the liquid flows into the cavity from bottom to top, the water flow will impact the impeller 18 to rotate when flowing through the impeller 18, and then drive the brush roller 20 to roll synchronously, thereby cleaning the outer surface of the camera in contact. The water flow overflowing from the top end of the cavity will be directly sprayed through the spray nozzle 14, cooperating with the brush roller 20 to perform the camera cleaning operation by spraying water, which is convenient to use.

During passive rotation of the brush roller 20, the soft brush 2001 thereon abuts against the outer surface of the camera and is self-adaptively adjusted to fit the camera according to the outer shape structure of the camera. For example, when one of the soft brushes 2001 abuts against the surface of the camera during rotation, it is supported to move backward by the convex-concave structure such as the curved surface of the camera surface, thereby driving the frame plate 2002 to synchronously slide in the horizontal opening or the vertical opening, so that one of the two elastic members 2003 in the frame plate 2002 is in a compressed state and the other is in a stretched state, so that the other soft brush 2001 opposite to the soft brush 2001 on the frame plate 2002 moves backward, thereby forming a self-adaptive fitting and cleaning operation according to the actual outer shape structure of the camera, and improving the cleaning effect.

[0033] In use, the device is pushed to the point to be used. The motor a501 is controlled to start, thereby driving the wire roller 5 to rotate, and the connection plate 16 is pulled up or lowered in the sliding groove 401 by winding or unwinding the connecting rope 502, thereby adjusting the use height of the combined cleaning component according to the position of the aerial camera. Then the motor b1101 is controlled to drive, so that the motor b1101 drives the support rod 701 to move upward along the U-shaped seat 7 under the meshing transmission of the gear, thereby adjusting the use height of the work plate 6 and the structure thereon according to the actual demand.

[0034] When working, first control the water pump 8 to start, extract the liquid in the water tank 2, and deliver to the cavity through the first corrugated pipe 801. When the liquid flowing into the cavity flows from bottom to top, the water flow will impact the impeller 18 to rotate when flowing through the impeller 18, and then drive the brush roller 20 to roll synchronously, thereby cleaning the outer surface of the camera in contact. The water flow from the top of the cavity will be directly sprayed through the spray nozzle 14, cooperating with the brush roller 20 to clean the camera by spraying water. After cleaning, control the support rod 701 to reset, and during the descending period, the bottom end of the support rod 701 will squeeze the folding air bag 9, thereby making the air flow in the folding air bag 9 spray to the front camera in an arc array through the air spray head 19, effectively improving the drying speed of the camera and reducing the probability of secondary adhesion of dust.
