Problems solved by technology

Manual cleaning of the lens in the tunnel requires the use of an electric maintenance vehicle, which belongs to high-altitude operations. At least one lane is occupied for maintenance during operation, and multiple people are required to observe the road conditions. The actual maintenance is difficult, dangerous, and costly.
Due to the poor automatic cleaning effect due to the attachment of oil stains, some stains are difficult to remove, the cost of manual cleaning is high, and the construction safety hazard in the tunnel is relatively large

Abstract

The invention discloses a roller type self-cleaning lens shield for highway tunnel monitoring, and mainly relates to the field of monitoring lens cleaning devices. The cover comprises a lens protection cover, a control device and a lens protection device, the lens protection cover is of a shell structure, a camera is arranged in the lens protection cover; the front end of the lens protection coveris fixedly connected with a shield lens; the lens protection device comprises a rolling-in roller, a rolling-out roller and a lens protection film, the rolling-out roller is arranged above the protective cover and is rotationally connected with the protective cover; wherein the rolling-in roller and the rolling-out roller are correspondingly arranged below the protective cover and are rotationally connected with the protective cover, one end of the lens protective film is wound on the rolling-out roller, the other end of the lens protective film is wound on the rolling-in roller around the front end face of the lens, and the control device is arranged below the lens protective cover and controls the rolling-in roller to rotate. The beneficial effects of the invention are that the transparent material is used as the lens shield protection part, and the mechanical device is used for regular automatic replacement, so that the lens cleaning purpose is achieved.

Description

technical field [0001] The invention relates to the field of monitoring lens cleaning devices, in particular to a roller-type self-cleaning lens shield for expressway tunnel monitoring. Background technique [0002] Highway tunnels are the focus of traffic safety management and also the difficulty of traffic management. The installation of video monitoring equipment in the tunnel is an effective means to improve the monitoring of highway tunnels. However, due to the closed space in the tunnel, the exhaust gas of large vehicles, dust, etc. form greasy adhesion to the camera lens, which seriously affects the monitoring effect. At present, the automatic cleaning of the lens mainly adopts the methods of adding wipers, cleaning the fixed lens through ventilation, or manually cleaning the lens. Manual cleaning of the lens in the tunnel requires the use of an electric maintenance vehicle, which belongs to high-altitude operations. At least one lane is occupied for maintenance dur...
