[0002] Satellite emergency communication vehicle is a mobile emergency communication system, through the vehicle platform of going to the emergency scene, sets up the communication network and processes the picture, video, voice etc.

[0003] Although static satellite vehicle can realize the communication of different modes and different frequency bands, the static satellite vehicle itself has no protection. At present, there is no static satellite vehicle with its own protection measures on the market. The static satellite vehicle is mainly interfered by low-flying vehicles. To solve this problem, corresponding measures are needed. The present application adopts radio detection to find low-flying vehicles, and uses radar to guide the jammer to interfere with the target. By interfering with the frequency band of the aircraft, the threat to itself is removed.

[0004] Based on this, the company adds radio detection, radar, jammer and other equipment to the static satellite vehicle to realize self-protection. When the static satellite vehicle is performing tasks, the satellite system and the radio detection start working at the same time; the satellite system is responsible for the whole vehicle communication, and the radio detection is responsible for the whole vehicle warning detection within ten kilometers; when low-flying vehicles invade, the system automatically raises the radar to search for the target; when the radar searches for the target, the jammer is guided to interfere with the aircraft, so as to remove the threat.

[0037] The bottom of the phased array radar 1 and the interference device 7 has two corresponding ear seats 101 on both sides, and a double-output shaft stepping self-locking motor 3 is arranged between the two ear seats 101; an auxiliary barrel 5 is fixed at the bottom of the double-output shaft stepping self-locking motor 3, the auxiliary barrel 5 is buckled on a disc stepping self-locking motor 4, and the disc stepping self-locking motor 4 is arranged on the top of the vehicle body 2 through an auxiliary structure;

[0038] When the phased array radar 1 or the interference device 7 needs to be adjusted: the disc stepping self-locking motor 4 rotates in the horizontal plane through the auxiliary barrel 5 and the double-output shaft stepping self-locking motor 3; the double-output shaft stepping self-locking motor 3 directly drives the phased array radar 1 or the interference device to adjust the pitch angle; compared with the traditional phased array radar which needs a telescopic rod for pitch adjustment and a gear disc and a driving motor for horizontal rotation adjustment, the design structure of the present application is more compact, occupies less space, and has lower cost.

[0039] The reduced structure design of the present application makes the gravity of the phased array radar 1 rely on the disc stepping self-locking motor 4 to bear, and the bearing capacity is not enough in the case of the traditional design which has a corresponding seat and a gear disc and has sufficient bearing capacity, so the auxiliary barrel 5 is used to improve the bearing capacity;

[0046] In this embodiment, a plurality of spring groups A 603 are arranged at the bottom of the conical groove in the vertical direction, and the conical block 601 is arranged on the spring group A 603; the spring group A allows a certain gap to be formed between the conical block and the base in the circumferential direction, which facilitates the smooth insertion of the insertion rod into the insertion hole; after the insertion is completed, the lifting mechanism is released, and under the action of gravity, the spring group A is compressed, and the conical block and the conical groove are tightly attached in the circumferential direction, i.e., the structure of the insertion rod 402 being inserted into the insertion hole first and then being locked.
