Horizontal fixed-angle-deflection bearing platform for fixed-point full-plane scanning detection

Abstract

The invention discloses a horizontal fixed-angle-deflection bearing platform for fixed-point full-plane scanning detection. A wedge slot and a locking bolt are arranged on a cover of the platform, and a metal block for limiting a largest deflection angle is arranged on the inner surface of the platform; a lower bottom plate is embedded and installed on the bottom of a metal shell; a fixed rod is arranged on an upper bottom plate which is provided with a limit protection switch; a direct current reduction motor is arranged on the back of the upper bottom plate, and a stirring pull rod is arranged on the front surface of the upper bottom plate; a platy pressure-loaded bearing is connected with a shaft sleeve; and an indexing control signal circuit board is fixed on the front surface of the upper bottom plate, and an indexing signal rotating arm is fixed on the shaft sleeve and is in friction contact with the indexing control signal circuit board. The horizontal fixed-angle-deflection bearing platform has the characteristics of being strong in bearing capacity, stable in rotation, accurate in deflection angle, not afraid of raining, and the like; in addition, a radar detector does not need to be moved in detection. The horizontal fixed-angle-deflection bearing platform has the advantages of being high in automation degree, high in detection speed and accurate in time-division detection area, avoiding leakage and repeatability of the detection, being capable of generating organism distribution planar graphs and the like.

Description

technical field [0001] The invention belongs to a radar life detector, in particular to a horizontal fixed-angle deflection bearing platform for fixed-point full-plane scanning detection. Background technique [0002] In life detection, it is often necessary to monitor and detect whether there are hidden life forms behind buildings. However, conventional radar life detectors can only detect a certain cone area. If you want to complete the detection of the entire plane area behind the building or the entire room, you need to constantly move the radar life detector, change the detection direction and angle, and after many It takes only one detection to complete the detection of the entire plane area or room. [0003] But it is a rigorous scientific problem to change the detection azimuth and angle of the radar life detector. If the amount of transformation and movement is too large and exceeds the coverage of the detection radar beam, there will be a missed detection area, r...

Problems solved by technology

[0004] The present invention aims at the life detection existing in the prior art that needs to continuously move the radar life detector, change the detection azimuth and angle to complete the detection of the entire plane area or room, if the angle change and movement are too large and exceed the coverage of the detection radar beam , there will be a missed detection area, resulting in the missed detection of life, which will cause the life to lose the chance of being discovered and rescued, and thus lose life; The number of error messages is more than the actual number, which will add unnecessary troubles to the follow-up rescue. A horizontal fixed-angle deflection bearing platform device for fixed-point full-plane automatic deflection scanning detection of radar life detectors is proposed.
