Security monitoring device

Abstract

The invention relates to the technical field of monitoring, in particular to a security monitoring device which comprises a rack, a movable plate and a monitoring host, a motor is fixedly connected to the rack, the movable plate is fixedly connected with an output shaft of the motor, the monitoring host is located on the movable plate and fixedly connected with the movable plate, and a light transmitting mirror is arranged on a front panel of the monitoring host. A cam and an air barrel matched with the cam are fixedly connected to a transmission shaft, an air storage box is arranged on the movable plate, a piston is arranged in the air storage box, a push rod provided with a rack is fixedly connected to the piston, a gear meshed with the rack and a rotating sleeve capable of being in contact with or disconnected from the gear are arranged on the movable plate, and a cleaning mechanism for cleaning the light transmitting mirror is arranged on the rotating sleeve. According to the scheme, a series of devices which correlate and interact are arranged to convert the rotary motion of the monitoring host into rhythmic automatic cleaning of the light transmitting mirror, so that the light transmission of the light transmitting mirror is effectively improved to improve the monitoring quality of the monitoring host, and meanwhile, the danger and high labor cost generated during manual cleaning are avoided.

Description

technical field [0001] The invention relates to the technical field of monitoring, in particular to a security monitoring device. Background technique [0002] As an effective means of security, security monitoring devices have been widely used in scenes such as factories, docks, communities, and prisons. Due to the high pollution of dust in the environment where the above-mentioned security monitoring devices are located, the photography of security monitoring devices in the above-mentioned use environment A large amount of dust and other pollutants often accumulate on the light-transmitting mirror of the camera head, which greatly reduces the light-transmitting performance of the light-transmitting mirror, making the video captured by the camera blurry, and failing to achieve the purpose of security monitoring. In order to achieve the purpose of security monitoring, The light-transmitting lens of the camera head needs to be cleaned. However, the camera head of the existing...

[0002] As an effective means of security, security monitoring devices have been widely used in scenes such as factories, docks, communities, and prisons. Due to the high pollution of dust in the environment where the above-mentioned security monitoring devices are located, the photography of security monitoring devices in the above-mentioned use environment A large amount of dust and other pollutants often accumulate on the light-transmitting mirror of the camera head, which greatly reduces the light-transmitting performance of the light-transmitting mirror, making the video captured by the camera blurry, and failing to achieve the purpose of security monitoring. In order to achieve the purpose of security monitoring, The light-transmitting lens of the camera head needs to be cleaned. However, the camera head of the existing monitoring device needs to be manually cleaned irregularly. The security monitoring equipment is usually located at a higher position and the monitoring host needs to go back and forth. Rotate to expand the monitoring range, so it is inconvenient to manually clean the light-transmitting lens of the camera, and it is also prone to dangerous accidents
