Automatic dust removal heat dissipation monitoring camera

Abstract

The invention relates to an automatic dust removal heat dissipation monitoring camera. The automatic dust removal heat dissipation monitoring camera comprises a shell and a lens. A heat absorption cavity is fixed in the shell. An electromagnet element is mounted at the bottom of the heat absorption cavity. An air jet hole is arranged at the top of the heat absorption cavity. An air guide tube communicates with the air jet hole. The air outlet end of the air guide tube stretches out of the shell and is close to the lens. A piston plate made of a ferromagnetic material is mounted in the heat absorption cavity in a sliding mode. The piston plate and the electromagnet element are connected through a pressure spring. A unidirectional air inlet tube is mounted on a side wall of the heat absorption cavity. The unidirectional air inlet tube is close to the top of the heat absorption cavity. A normally closed pressure valve is mounted at the air jet hole. The normally closed pressure valve is close to a pressure sensitive switch. The pressure sensitive switch is connected with the circuit of the electromagnet element in series. The monitoring camera is simple in structure and convenient to maintain, and the service life is effectively prolonged.

Description

technical field [0001] The invention relates to a security equipment, in particular, a camera. Background technique [0002] Security monitoring system is a new major that people pay more and more attention to.

[0002] Security monitoring system is a new major that people pay more and more attention to. As far as the current development is concerned, the application of security system engineering is becoming more and more popular, and the technological content is getting higher and higher; especially the advent of the information age provides an opportunity for the development of this major. The traditional monitoring system includes front-end cameras, transmission cables, and video monitoring platforms. Cameras can be divided into network digital cameras and analog cameras, which can be used as front-end video image signal collection. Video monitoring is intuitive, accurate, timely, and rich in information. It is widely used in many occasions; in recent years, with the rapid development of computer, network, image processing and transmission technology, video surveillance technology has also made great progress. Existing surveillance cameras are generally exposed outdoors. There is a dust-proof cover at the end, which can block the dust and rainwater in the air to prevent dust and rainwater from adhering to the see-through glass plate of the camera, which will affect the shooting quality of the surveillance camera and thus affect its monitoring effect; at the same time, the monitoring The installation position of the camera is generally high, which is not conducive to manual cleaning and maintenance, and the shooting quality of the surveillance camera will also be affected after long-term use; and the existing surveillance cameras generally adopt a fully enclosed structure for the purpose of waterproofing , using this structure, when the surveillance camera is in a hot environment, it is not conducive to heat dissipation of the equipment, and the internal structure of the surveillance camera is easily damaged under high temperature, which affects the service life of the surveillance camera
