Technical Field

The invention relates to the technical field of radars, in particular to a coil spring type multi-cable anti-winding automatic winding device and a radar.

Background

With the development and application of radar technology, higher and higher requirements are put forward on the performance of radar, and in particular, mobile radars such as vehicle-mounted radars and ship-mounted radars are researched and applied more and more widely due to the characteristics of high precision, high integration and multiple functions. The radar mainly comprises a base, a rotary table, an antenna and other mechanisms, wherein the rotary table is used as a mechanical scanning part of the radar, is responsible for target angle tracking during the working of the radar, and simultaneously also plays a role in load and signal transmission between the rotary antenna of the radar and ground fixing equipment. The typical turntable is composed of a support rotating device, a power driving device, a position detection device, a rotating combination, a safety protection device and the like. The power supply and signal transmission between the rotating part and the fixed part of the radar in the rotating process are mainly realized by the rotating combination.

Due to different application scenes, most radars require that the turntable can drive the antenna to realize continuous rotation at a rotation angle of-360 degrees or bidirectional continuous infinite rotation. At present, the rotary combination of the radar rotary table at home and abroad mainly has two forms of a rotary drag chain and a collector ring.

The rotary drag chain is formed by superposing and combining a plurality of parts capable of rotating to a certain angle along the axis direction, the more the parts are, the larger the rotatable angle is, the cable penetrates through the center of the rotary drag chain and rotates along with the drag chain, so that the cable rotates at a certain angle, the price is relatively cheap, the technology is mature, and the rotary drag chain is more applied to a system which continuously rotates at a rotating angle of-180 degrees and has a larger size space. However, when the number of cables is large and the rotation angle is increased, the dimension in the axial direction is large, and it is difficult to apply the cable to a system having a large rotation angle and a limited space dimension.

The collector ring is formed by superposing a plurality of signal channels, can realize continuous infinite transmission of electric power and a plurality of signals, the larger the transmitted power is, the larger the signals are, the larger the sizes of the collector ring in the neck direction and the axis direction are, the higher the price is, the technology is relatively mature, a special processing technology is required, the design and the processing are difficult, the applicable environment is limited, and the collector ring is more applied to a system which continuously and infinitely rotates in the forward and reverse directions and has allowable space size and price. In the prior art, for example, chinese patent application with publication number CN111969292A discloses a compact radar antenna turntable, which includes an azimuth adjustment unit and a pitch adjustment unit. The azimuth adjusting unit comprises a shell, a disc type motor, a gear transmission mechanism, an output flange, a collecting ring and an encoder; gear drive includes the driving gear, change gear assembly, driven gear, driving gear fixed mounting is on disc motor's output shaft to be connected with driven gear transmission through change gear assembly, the fixed suit of driven gear is in the output flange outside, the lower extreme and the shell rotatable coupling of output flange, the shell is stretched out to the upper end, the collector ring sets up in the cavity intracavity of output flange, encoder driving disk and driven gear's lower fixed surface is connected. The pitching adjusting unit comprises a supporting seat, a pitching shaft, a tightening ring for mounting the radar antenna and a locking mechanism; supporting seat fixed mounting is in output flange upper end, and the tight hoop both ends are articulated with the supporting seat through every single move axle respectively, and locking mechanism is used for the every single move gesture of fixed tight hoop. The adopted mode is a slip ring rotating combination.

The existing radar rotary table rotary combination cannot provide a stable and reliable rotary combination with a larger rotation angle, low price, smaller axial size and strong applicability, so that the high-precision multifunctional radar cannot be subjected to high-integration research.
