[0022] As an improvement, a telescopic stabilizing mechanism is provided at the lower end of the interference electromagnetic wave transmitting antenna 5 .

[0023] Furthermore, the telescopic stabilization mechanism is composed of a stabilizing screw drive shaft 9, a transmitting antenna stabilizing screw 10 and a stabilizing screw drive motor 11. The stabilizing screw drive motor 11 is fixedly arranged on the lower end surface of the supporting device connecting plate 3. The output shaft of the stabilizing screw drive motor 11 is connected to one end of the stabilizing screw drive shaft 9. The transmitting antenna stabilizing screw 10 is arranged on the other end of the stabilizing screw drive shaft 9. The transmitting antenna stabilizing screw 10 is threadedly connected to the lower end surface of the interfering electromagnetic wave transmitting antenna 5.

[0024] As an improvement, the stabilizing screw drive motor 11 is connected to the stabilizing screw drive shaft 9 via a reducer.

[0025] As an improvement, the multi-angle supporting link 6 is detachably connected to the angle motor connecting swing arm 7 and the supporting device connecting plate 3 via a quick-release connecting device.

[0026] Specifically, the quick-release connecting device is composed of a first supporting link 61, a second supporting link 62, a link tensioning spring 63, a tensioning spring hook 64, a hemispherical rotating shell 65 and a ball head connecting piece 66. Each group of the multi-angle supporting links 6 is composed of the first supporting link 61 and the second supporting link 62. Both ends of the first supporting link 61 and the second supporting link 62 are fixedly provided with a hemispherical rotating shell 65. The angle motor connecting swing arm 7 and the supporting device connecting plate 3 are both provided with a ball head connecting piece 66.

The first supporting link 61 and the second supporting link 62 are detachably connected to the two ends of the link tensioning spring 63 through the tensioning spring hook 64.

[0027] Preferably, there are three connecting swing arm drive motors 8, three multi-angle support connecting rods 6 and three angle motor connecting swing arms 7, and the three connecting swing arm drive motors 8 correspond to the multi-angle support connecting rods 6 and the angle motor connecting swing arms 7 respectively, and the three connecting swing arm drive motors 8 are evenly distributed on the lower end surface of the interference electromagnetic wave transmitting antenna 5.

[0028] The working principle of the present invention is as follows:

[0029] When the present invention is used, the arc-shaped electromagnetic wave reflection bowl 1 is fixed to the ground through the reflection bowl fixing base 2, and the multi-angle support device is supported by the support device connecting plate 3 and the connecting plate fixing bracket 4. Three connecting swing arm driving motors 8 are installed at the lower end of the interference electromagnetic wave transmitting antenna 5, and the three connecting swing arm driving motors 8 drive the corresponding connected angle motor connecting swing arm 7 to swing.

When the three connecting swing arm driving motors 8 drive the angle motor connecting swing arm 7 to swing at the same time, the distance between the interference electromagnetic wave transmitting antenna 5 and the arc-shaped electromagnetic wave reflection bowl 1 can be changed, thereby changing the range and focus of the electromagnetic wave. At the same time, the stabilizing screw driving motor 11 drives the stabilizing screw driving shaft 9 and the threaded connection between the transmitting antenna stabilizing screw 10 and the interference electromagnetic wave transmitting antenna 5 can also change the interference. The distance of the electromagnetic wave transmitting antenna 5 is different from that of the electromagnetic wave transmitting antenna 5. When the transmitting antenna stabilizing screw 10 is connected to the interfering electromagnetic wave transmitting antenna 5, the stability of the interfering electromagnetic wave transmitting antenna 5 can be ensured. The transmitting antenna stabilizing screw 10 has only a certain length. When the transmitting antenna stabilizing screw 10 is rotated to the farthest end, it is separated from the interfering electromagnetic wave transmitting antenna 5. Then, the interfering electromagnetic wave transmitting antenna 5 can change its angle and make the distance change farther. In addition, the use of a quick-release connection structure to connect the interfering electromagnetic wave transmitting antenna 5 can be convenient for replacement, disassembly and maintenance. The quick-release structure is provided with a hemispherical rotating shell 65 on the first supporting link 61 and the second supporting link 62. The first supporting link 61 and the second supporting link 62 are tightened by the connecting rod tensioning spring 63 to cover the hemispherical rotating shell 65 on the ball head connector 66. When disassembling, it is only necessary to pull the first supporting link 61 and the second supporting link 62 apart by a certain distance to disassemble, and the disassembly, installation and connection are convenient.
