Description

Technical Field

[0001] The present application relates to the field of camera cleaning devices, and in particular to a video monitoring device for icing of a rail transit contact network. Background Art

[0002] The rail transit contact network is the contact network of the rail transit power supply system, which is mainly used to provide power for passing trains. However, in winter, the rail transit contact network is prone to ice formation. It is necessary to monitor the status of the rail transit contact network through cameras in order to detect and solve problems in time and ensure its normal operation.

[0003] Over long-term use, rain, snow, dust, and dirt easily accumulate on the lens surface of external cameras. These stains not only affect camera quality but can also cause performance degradation. Therefore, regular cleaning of the camera lens is crucial to ensuring proper operation. However, existing cleaning methods often require manual labor and are inefficient. Utility Model Content

[0007] By adopting the above technical solution, the operator drives the two sliders to move in opposite directions through the control component to drive the slide seat to slide, and then drives the scraper to clean the camera lens, thereby realizing automatic cleaning of the camera lens, which is beneficial to improve cleaning efficiency and ensure the normal operation of the camera.

[0008] Optionally, the control component includes two pulleys rotatably connected to the base, a belt is wound around the two pulleys, the two sliders are fixedly connected to the belts, and the movement of the belts can drive the two sliders to move in opposite directions, and a motor is provided on the base for controlling the rotation of one of the pulleys.

[0009] By adopting the above technical solution, the two sliders are fixedly connected to the belt, and the belt is divided into two strands by two pulleys. The two sliders can correspond to one strand of the belt respectively, so that when the motor drives one of the pulleys to rotate, it can drive the two sliders to move in opposite directions.

[0029] The following is combined with Figure 1-6 This application is described in further detail.

[0030] The present application discloses a video monitoring device for icing of a rail transit contact network. Figure 1 and Figure 2, the icing video monitoring device for the rail transit catenary includes a base 1. The base 1 is in a U shape and covers above the camera lens 19 to be used as a shield. The base 1 is fixedly connected to the camera body 18 to ensure that the entire cleaning device can be stably installed on the camera body 18.

[0031] As Figure 2 and Figure 3 , a sliding seat 12 is movably arranged in the base 1. Two mutually parallel guide rods 13 are fixedly connected to the inner wall of the base 1. The two guide rods 13 are mutually parallel, and the camera lens 19 is located between the two guide rods 13. The guide rod 13 slides through the sliding seat 12, so that the sliding seat 12 can be slidably arranged in the base 1. A scraping plate 11 for cleaning the camera lens 19 is fixedly connected to the sliding seat 12.

[0032] In order to realize the reciprocating movement of the sliding seat 12, two sliders 14 are slidably arranged on the base 1, and the sliding direction of the sliders 14 is perpendicular to the sliding direction of the sliding seat 12. Two connecting rods 15 are hinged to both sliders 14. The ends of the two connecting rods 15 far from the sliders 14 are both hinged to the sliding seat 12.

[0033] As Figure 3 and Figure 4 , a control component 2 for controlling the reverse movement of the two sliders 14 is arranged on the base 1. The control component 2 mainly includes two pulleys 21 rotatably connected to the base 1 and a motor 23. The output shaft of the motor 23 is coaxially传动连接 (这里原文可能有误,推测是driven连接) with one of the pulleys. A belt 22 is wound between the two pulleys 21. Both sliders 14 are fixedly connected to the belt 22. When the pulley 21 rotates, it drives the belt 22 to move and can drive the two sliders 14 to move in the reverse direction. When the slider 14 moves, under the transmission of the connecting rod 15, it can drive the sliding seat 12 to drive the scraping plate 11 to clean the surface of the camera lens 19.

[0034] As Figure 5 and Figure 6 , in order to improve the cleaning effect, a turning plate 17 is also hinged to the sliding seat 12. The scraping plate 11 is detachably and fixedly connected to the side of the turning plate 17 facing the camera lens 19. A turning component 3 is arranged on the base 1 for controlling the turning of the turning plate 17 towards or away from the camera lens 19.

[0035] The flip assembly 3 includes a plurality of limiting rods 31, which are fixedly connected to the base 1. The flip plate 17 is provided with an elongated hole 32 for the limiting rods 31 to pass through. An end plate 34 is fixedly connected to one end of the limiting rod 31 that passes through the elongated hole 32. A spring 33 is provided on the limiting rod 31 between the end plate 34 and the flip plate 17. When the spring 33 is in its natural state, it pushes the flip plate 17 toward the camera lens 19, causing the scraper 11 to rest against the camera lens 19. A push block 35 is fixedly connected to the inner wall of the base 1 near the pulley 21, and the push block 35 is capable of pushing the flip plate 17 to flip away from the camera lens 19. When the slide 12 slides on the base 1, it will drive the flip plate 17 to move. When the flip plate 17 moves to the position where the push block 35 is set on the base 1, the push block 35 will push the flip plate 17 to flip the flip plate 17 away from the camera lens 19, and the scraper 11 will leave the camera lens 19, so that the operator can remove and replace the scraper 11.

[0036] In order to further improve the cleaning effect, a nozzle (not shown) can be fixedly connected to the base 1, which is used to spray cleaning liquid toward the camera lens 19. Before cleaning, the cleaning liquid can be sprayed toward the camera lens 19 through the nozzle to soften the stains on the lens, making it easier for the scraper 11 to clean it.

[0037] The operating principle of the present embodiment is as follows: The rail transit overhead wire ice coverage video monitoring device of the present invention uses a motor 23 to drive a pulley 21 to rotate, driving a slider 14 to move on a base 1. This, in turn, drives a connecting rod 15 to move a slide 12 and a flip plate 17, enabling a scraper 11 to clean a camera lens 19. Simultaneously, the provision of a guide rod 13 and a flip assembly 3 ensures stable movement and flipping of the slide 12 and flip plate 17. Furthermore, a nozzle is used to spray cleaning fluid onto the camera lens 19, enhancing the cleaning effect.

[0038] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
