[0002] The three-dimensional electromagnetic beam formed by the radar antenna in space is usually described by the horizontal and vertical cross-sectional views of the beam. The radiation pattern is petal-shaped, also known as a lobe pattern. A conventional antenna radiation pattern has a main lobe and multiple side lobes. After the radar antenna is assembled, it is usually fixed and debugged as needed to ensure the effectiveness of the radar.

[0003] The utility model with the existing authorization announcement number CN219286642U discloses a device for fixing a radar antenna, including a geological radar body, a radar antenna fixing frame is arranged on the outside of the geological radar body, a retractable shock absorber is arranged on the lower side of the radar antenna fixing frame, a fixed chassis is arranged on the lower side of the retractable shock absorber, and both ends of the retractable shock absorber are respectively connected to the radar antenna fixing frame and the fixed chassis.

[0004] By adopting the above technical scheme, the retractable shock absorber can play a role in placing the geological radar body through the connection between itself and the radar antenna fixed frame, so that when the fixed chassis itself is placed on the detection trolley, the geological radar body can also be used smoothly, and the retractable shock absorber can play the role of support, force and shock absorption, and can freely retract itself so that the geological radar body can still fit tightly with the lining surface when the road surface is uneven and there is a slope. However, in the above technical scheme, it is not convenient to quickly debug the receiving direction of the radar antenna over a large range after the radar antenna is assembled and fixed, especially when the radar needs to adjust the angle greatly, the staff needs to manually move the radar antenna position to ensure that the radar antenna angle can be changed over a large range under normal power supply conditions, which greatly affects the convenience of debugging the radar antenna after assembly and fixation.

[0005] Therefore, we propose a radar antenna assembly, debugging and fixing device to solve the above problems. Utility Model Content

The side of each reinforcing block 17 close to the fixing seat 1 is fixedly connected to the outer surface of the fixing seat 1. The reinforcing blocks 17 can increase the connection firmness between the mounting plate 14 and the fixing seat 1, prevent the mounting plate 14 from being excessively loosened from the fixing seat 1, and improve the pressure-bearing capacity of the mounting plate 14.

[0027] The output end of the power of the rotating motor 5 is fixedly connected with a small gear 6, which meshes with the large gear 4. The inner wall of the fixed seat 1 is fixedly connected with a stable bearing 18. The inner wall of the inner ring of the stable bearing 18 is fixedly connected to the outer surface of the adjusting seat 2. The stable bearing 18 can increase the stability of the connection between the adjusting seat 2 and the fixed seat 1 without affecting the smooth rotation of the adjusting seat 2, thereby ensuring the stable rotation of the adjusting seat 2.

[0028] Two power connection plates 7 are arranged inside the fixing seat 1, wherein the upper surface of one of the power connection plates 7 is fixedly connected to the bottom surface of the adjusting seat 2, and two conductive carbon rings 8 are fixedly connected to the side surfaces of the two power connection plates 7 close to each other, and the side surfaces of each group of conductive carbon rings 8 close to each other are in contact, and a reinforcement frame 19 is fixedly connected to the outer surface of the rotating motor 5, and the back surface of the reinforcement frame 19 is fixedly connected to the front surface of the fixing seat 1, and the reinforcement frame 19 can reinforce the rotating motor 5, so that the connection between the rotating motor 5 and the fixing seat 1 is more firm and reliable.

[0029] A plurality of compression springs 9 are fixedly connected to the bottom surface of the other power connection board 7, and the bottom end of each compression spring 9 is fixedly connected to the inner bottom wall of the fixing seat 1. A rubber ring 20 is fixedly connected to the bottom surface of one of the power connection boards 7, and the bottom surface of the rubber ring 20 is in contact with the upper surface of the other power connection board 7.

The stabilizing seat 22 can increase the stability of the servo motor 11, so that the servo motor 11 can smoothly drive the screw 10 to rotate, thereby ensuring the stable operation of the servo motor 11.

[0032] The working principle of the utility model is: when in use, first use the wiring tube 16 to connect the positive and negative poles of the power line to the conductive carbon ring 8 below respectively, and at the same time, the rotating motor 5 is powered on, and the servo motor 11 is also powered on through the conductive carbon ring 8. At this time, the power provided by the rotating motor 5 cooperates with the fixing seat 1 and the reinforcement frame 19 to rotate the small gear 6, and then through the meshing connection relationship between the small gear 6 and the large gear 4, the adjustment seat 2 and the antenna body 3 can be driven to quickly perform a large range and large angle horizontal adjustment, and when the adjustment seat 2 rotates, the upper power board 7 and the conductive carbon ring 8 will be driven to rotate.
