Description

A General Structure for Electronic Equipment Protection

technical field

The invention relates to a general structure for electronic equipment protection, which is used for electromagnetic and environmental protection of electronic equipment, and specifically relates to the sealing, cut-off waveguide and heat dissipation structure of the electronic equipment shell.

Background technique

The 500m aperture spherical radio telescope FAST (Five-hundred-meter Aperture Sphericalradio Telescope) will be the largest and most sensitive radio astronomy telescope in the world. Using the karst depression in Guizhou as the station site, a spherical crown reflector is laid in the depression, and a parabola is formed through active control to converge electromagnetic waves. A light steel cable is used to drag the feed platform to realize the pointing and tracking of the telescope.

The reference surface of the FAST active reflector is a spherical surface with a diameter of 500m and a radius of 300m, which is composed of a main support structure, an actuator and a reflector unit. The main support structure of the active reflector consists of ring beams, lattice columns, lattice column foundations, main cable nets, and down cables. The main cable net is a geodesic triangular grid, and the triangular reflecting surface units are installed on the main cable net. The side length is about 10.4m~12.4m, and the number is about 4300 pieces.

When the telescope is observing, the actuator is used to drive the pull-down cable to change the surface shape of the reflector unit to track celestial bodies. The actuator is an integrated unit of mechanics, electricity and hydraulics. It works in the humid depression in Qiannan, Guizhou. It always bears the maximum 7-15 tons of tension variable load, the average speed is about 0.2mm/s, and the number is 2225 sets.

Since the radio telescope requires avoiding electromagnetic interference, it is necessary to set up a protective structure for the actuator to prevent the electromagnetic waves generated during the operation of the actuator from interfering with the observation quality of the radio telescope. At the same time, it is also necessary to prevent the electromagnetic wave interference generated by the radio telescope and other types of equipment. The operation of the actuator, and the working environment of the actuator is located outdoors, it is necessary to prevent rain, snow, wind and dust from affecting the actuator.

In the structural design of electronic equipment, three aspects are often involved: 1. Environmental protection issues; 2. Electromagnetic interference protection and anti-interference issues; 3. Heat dissipation issues; these three aspects are often combined to become A key factor in the structural design of electronic equipment.
