Lightweight fully sealed security surveillance radar structure

Abstract

The present invention relates to a lightweight fully sealed security surveillance radar structure which comprises a radome, a heat radiation bottom cover, a fixed part, a rotating part, a collector ring and a photoelectric encoder. The collector ring comprises collector ring stator and a collector ring rotor. The photoelectric encoder comprises an encoder stator and an encoder rotor. The lightweight fully sealed security surveillance radar structure has the advantages of good heat radiation performance, strong environmental adaptability, and a strong cost advantage.

Description

technical field [0001] The invention relates to a lightweight fully sealed security monitoring radar structure. Background technique [0002] In the existing radar structure, the indoor unit and the outdoor unit are generally separated, the front-end antenna feeder and the servo system are externally located, and other control processing extensions are located in the cabinet. In view of the large amount of data processed by the indoor units and the serious heat generation problem, most of them adopt cost-effective air-cooled heat dissipation to achieve thermal balance of the cabinet. However, an air-cooled design requires drawing in cool air from the atmosphere and expelling the hot air into the atmosphere after heat exchange. Therefore, complete sealing cannot be achieved. In salt fog or dusty environments, it is necessary to build computer rooms for indoor unit cabinets, which consumes manpower and material resources, and it is difficult to build computer rooms in most co...

Problems solved by technology

Therefore, complete sealing cannot be achieved. In salt fog or dusty environments, it is necessary to build computer rooms for indoor unit cabinets, which consumes manpower and material resources, and it is difficult to build computer rooms in most coastal defense environments.

[0003] The existing radar adopts a fully sealed integrated structure, such as Figure 8 As shown, including the radome and the radar cavity, the heat dissipation side plates are arranged on the radar cavity. In order to better realize natural convection, the vertical height and area of ​​the cooling teeth are required to be large enough, so that the height of the radar cavity is relatively high. Compared with the radome with paper honeycomb structure, the radar cavity and heat dissipation side panels are made of aluminum alloy, which will increase the quality of the product
