A dual-system shipboard radar antenna base

Abstract

The invention discloses a dual-system shipborne radar antenna pedestal, which is characterized in that an azimuth big gear (turntable), an azimuth small gear and a double-piece gear are designed on abase, and sealed protection is performed by using a gear cover, a labyrinth cover plate and a labyrinth cover plate sealing ring. The base is divided into a main cavity, a left auxiliary cavity and aright auxiliary cavity which are connected. On the other hand, heat dissipation air channels can be formed, thereby increasing the heat dissipation area, and being conducive to heat dissipation of theequipment. The main cavity and the left auxiliary cavity form a left heat dissipation air channel therebetween, and the main cavity and the right auxiliary cavity form a right heat dissipation air channel therebetween. The left and right side walls of each heat dissipation air channel are provided with heat dissipation fins, and the internal part can form natural wind channels from bottom to topand from front to back. Heating devices in the main cavity, the left auxiliary cavity and the right auxiliary cavity are installed on the back walls of the air channel fins, the heat is transmitted tothe corresponding heat dissipation fins through the conduction of the cavity walls, and then the fins perform heat exchange with the external air so as to conduct the heat in the antenna pedestal tothe external air.

Description

technical field [0001] The invention relates to a dual-system shipborne radar antenna seat and the field of mechanical and electronic structures. Background technique [0002] Marine navigation radar usually has a pulse system and a continuous wave system, and the radars of these two systems have their own advantages and disadvantages. The pulse system navigation radar has a long detection range, but its target resolution is low, and the continuous wave system navigation radar has a high target resolution, but its detection range is short. The dual-system shipborne radar is composed of two single-system shipboard radars. Compared with the single-system shipboard radar, it has a longer detection distance, higher detection accuracy, and excellent ship navigation capabilities. The main work of the combined single-system shipborne radar is to combine the single-system shipborne radar outdoor unit. The outdoor unit mainly includes antenna feeder system, transmitter, receiver, s...

Problems solved by technology

If the natural heat dissipation method of increasing the heat dissipation area of ​​the heating equipment is adopted, the volume and weight of the antenna seat designed by this method will be large, which is not suitable for shipboard use; if the fan is used for forced air cooling, this will absorb the external rainwater and Salt mist blowing on the radar equipment is not conducive to the protection of the radar equipment; if cooling equipment such as air conditioners is added outside the installation space to dissipate heat, this will not only increase the cost of the antenna base, but also increase the volume, weight and complexity of the antenna base
