Description

Technical Field

[0001] The invention belongs to an antenna bracket for satellite navigation signal interference, and in particular relates to a quick-disassembly and adjustable three-way transmitting antenna mounting bracket. Background Art

[0002] Satellite navigation is widely used in civilian applications and is an indispensable navigation method. In order to test the anti-interference ability of satellite navigation antennas and navigation signal receivers, it is necessary to conduct experiments such as suppression and deception on satellite receiving devices. In order to detect the anti-interference ability of satellite receiving antennas, it is necessary to use signal interference sources to suppress signals or deceiving signals to the receiving device from multiple directions at the same time, and implement all-round suppression and deception. In the experiment, it is necessary to use an antenna bracket to fix the position of the signal transmitting antenna.

[0003] In existing solutions, fixed antenna brackets are usually used to install transmitting antennas, and the antenna poles are usually tied to the fixed brackets with fastening belts. Fixed antenna brackets are large in size, occupy a large space, and are not easy to transport. The installation process of fixed antenna brackets is complicated. If experiments are required in multiple directions, the fixed antenna brackets need to be installed and fixed one by one in different directions and positions, which is time-consuming and labor-intensive. It is not easy to repair and replace the parts of fixed antenna brackets when they are damaged. The detection test methods that can be performed by fixed antenna brackets are single, and it is not easy to flexibly adjust the device. The parameters such as the position, height and angle of the transmitting antenna with the horizontal direction cannot be changed at will. It is difficult to verify the signal attenuation caused by different wireless propagation distances and different transmitting and receiving angles. The fixed bracket is not effective in satellite signal stability experimental tests and needs further improvement. Summary of the invention

[0036] A quick-disassembly and adjustable three-way transmitting antenna mounting bracket device (inner diameter 292mm) specifically includes a large clamp 1, an inclined rod hexagonal screw 2, an inclined rod 3, a short connecting rod 4, a connecting rod joint 5, a countersunk screw 6, a dial 7, a small antenna 8, and a main antenna 9.

The installation position of the large clamp 1 can be adjusted within a range of 240mm to 440mm from the top of the main antenna pole.

[0039] The small clamp 10 is divided into two parts, front and back, which can be combined into one or disassembled into two halves. When combined, they are fastened and connected by two screws on the left and right sides, and are in a ring shape and fixed on the main antenna 9. A short connecting rod 4 is connected to the middle position of the front part of the small clamp 10, and an oblique short connecting rod 4 is connected to the left and right ends of the rear part of the large clamp 1. When the small clamp 10 is in a combined state, three short connecting rods 4 are connected in front and back, and the three short connecting rods are 120 degrees apart. Fasten the small clamp 10 to the main antenna 9 with an M10×50 hexagon socket screw. The installation position of the small clamp 10 can be adjusted within a range of 200mm to 390mm from the top of the main antenna pole.

[0040] The large clamp is used to install on the antenna pole with an outer diameter of 292mm, and the small clamp is used to install on the antenna pole with an outer diameter of 94mm.

[0041] The inclined rod 3 is connected to the large clamp 1 (or small clamp 10) at the bottom position with the inclined rod hexagon socket screw 2, and the inclined rod 3 is argon arc welded with the connecting rod joint 5 at the middle position and connected together with the hexagon socket screw M8×45. The connecting rod joint 5 is connected to the short connecting rod 4 with screws.

[0042] The structural diagram of the scale plate 7 of the quick disassembly and assembly adjustable three-way transmitting antenna mounting bracket device described in this embodiment is as follows Figure 3 The scale plate 7 comprises a column 11, a central hexagon socket screw 12, an adjusting screw 13, an M16 and 5 / 8-11 combination joint 14, a rotating plate 15, and the scale plate 7.

[0043] The M16 and 5 / 8-11 combination joint 14 and the rotating plate 15 are argon arc welded together, the dial 7 and the column 11 are argon arc welded together, and then connected together with an M8×25 inner center hexagon screw 12.

[0044] The top of the inclined rod 3 is connected to the dial 7 by a countersunk screw 6.

[0045] The column 11 and the rotating plate 15 are fastened together by a central hexagonal screw 12 .

[0046] The dial 7 is engraved with numbers such as 0, 15, 30, 45, 60, 75, 90, etc., which respectively represent the angle scales with the horizontal line.

[0047] The position of the rotating plate 15 can be adjusted by tightening the screw 13 (hexagon socket screw with a dial), so that the outer end of the rotating plate 15 can be rotated to positions corresponding to different angles to achieve the pitch change of the antenna bracket.

[0048] The M16 and 5 / 8-11 combined connector 14 can be connected to the small antenna 8 and can be rotatably installed through the connector thread.

[0049] In this embodiment, the function of the main antenna 9 is to receive normal satellite signals, such as COMPASS (Beidou) satellite signals, GPS (Global Positioning System) satellite signals, GNSS (Galileo) satellite signals, GLONASS (GLONASS) satellite signals, etc. The satellite signals received by the main antenna 9 are transmitted to the satellite navigation receiving device to display time, position, speed, and other information.

[0050] In this embodiment, the function of the small antenna 8 is to transmit the satellite suppression or deception signal emitted by the signal suppression source or deception source through the small antenna 8, and suppress or deceive the main antenna 9. The signal emitted by the antenna is transmitted through the air, and the intensity will be attenuated to a certain extent. The attenuation degree varies at different distances. The pitch adjustable structure can set different propagation distances to verify the interference degree of different attenuation signals on the satellite signal receiving device.

[0051] In this embodiment, the function of the dial 7 is to adjust the angle between the straight line opposite to the center of the small antenna 8 and the horizontal plane. The angle adjustment range is -90 degrees to 90 degrees. By adjusting the angle, the center of the small antenna 8 can be directly opposite to the main antenna 9, reducing the attenuation of the signal during propagation, so that the main antenna 9 can obtain the maximum interference power. At the same time, by adjusting different angles, the signal attenuation under different angles between the straight line opposite to the center of the small antenna 8 and the main antenna 9 can be verified.

[0052] In practice, the modules of a quick disassembly and assembly adjustable three-way transmitting antenna mounting bracket device can be connected to each other by screws and screws, the fixing position of the large clamp 1 (or small clamp 10) and the main antenna 9 is reasonably selected, and the rotating plate 15 is adjusted to a suitable position so that the center position of the small antenna 8 is directly opposite to the center position of the main antenna 9, and then the experimental measurement can be started. After measuring a set of data, the fixing position of the large clamp 1 (or small clamp 10) and the main antenna 9, the scale position of the rotating plate 15, and the facing angle of the small antenna can be readjusted to achieve pitch adjustment. In addition, three petal-type brackets at an angle of 120 degrees to each other can work at the same time, which is used to simulate signal interference and deception at different directions at the same time, and can also verify the stability and maximum interference power of the satellite signal receiving device under the condition of signal suppression and interference in three different directions. It is also possible to remove the brackets that are not needed in the three petal-type brackets due to actual needs, and only use one of the brackets or part of the brackets for measurement experiments. Three transmitting antennas with an angle of 120 degrees to each other can be installed, and the positions can be flexibly adjusted. After the measurement is completed, the bracket is disassembled into parts and stored separately. Among them, the adjustable short connecting rod 4 is combined with the large clamp 1 (or small clamp 10), which greatly saves storage space.
