[0034] When the deformation radar 3 moves back and forth in the horizontal direction, the direction changing device 7 can work by means of the rack 8 .

[0035] In this embodiment, the base 1 is further provided with an outer cover 11 for protecting the rack seat 9, and the inner side walls at both ends of the outer cover 11 are provided with reset rods 12. The reset rods 12 are used to push the extrusion block 75 when the direction-changing device 7 moves to the corresponding reset rod 12, so as to protect the rack 8 and prevent the rack from being covered by debris such as leaves and branches, which affects its use.

[0036] In this embodiment, the radar moving component 2 includes a moving rail 21 and a rail protection plate 22. The rail protection plate 22 covers the top of the moving rail 21. Dust collecting slopes 23 are provided at both ends of the rail protection plate 22. Control switches 24 are provided on the lower surfaces of both ends of the rail protection plate 22.

[0038] In this embodiment, the exhaust heat dissipation device 5 includes a telescopic exhaust hood 51, a crossflow fan blade 52, and an air duct 53.

At this time, the extrusion block 75 rises and compresses the telescopic exhaust hood 51 obliquely upward. When the small gear 72 needs to rotate to drive the rotating shaft and the crossflow fan blade 52 to rotate, the large gear 73 descends under the drive of the extrusion block 75 and meshes with the rack 8. The telescopic exhaust hood 51 will synchronously extend to push the rotating shaft 54 ​​and the small gear 72 on the rotating shaft 54 ​​obliquely downward. The small gear 72 is pushed out a distance sufficient for the large gear 73 to mesh with the large gear 73 when it descends, ensuring that the small gear 72 and the large gear 73 are always in a meshing state.

The dial blade 63 is a backward curved arc, which is convenient for receiving the airflow blown out by the air duct 53, and then blowing the hot air onto the slide rail protective plate 22 to heat the plate surface.

[0040] In this embodiment, the direction-changing device 7 includes a support block 71, two small gears 72, two large gears 73, two transmission gears 74, an extrusion block 75 and a reset spring 76. The two sides of the support block 71 are provided with symmetrically arranged bracket plates 711. The two large gears 73 and the two transmission gears 74 are rotatably connected to the mounting shafts at both ends of the bracket plate 711. The small gear 72 is fixed on the rotating shaft 54, and the small gear 72 is meshed with the large gear 73. The large gear 73 is meshed with the transmission gear 74 is coaxially mounted on the bracket plate 711, the transmission gear 74 can mesh with the rack 8, the extrusion block 75 is slidably mounted in the sliding hole 77 in the support block 71, the support block 71 is fixed to the side of the moving seat 25, and sliding bosses 78 are provided at both ends of the support block 71. The root of the bracket plate 711 is slidably mounted on the support block 71 through the sliding bosses 78. The return spring 76 is installed in the support block 71 and its two ends are respectively pressed between the support block 71 and the bracket plate 711;

[0041] Both ends of the sliding hole 77 in the support block 71 are provided with avoidance holes 79;

[0042] Both ends of the extrusion block 75 are provided with extrusion bosses 751, and the depth of the air avoidance hole 79 is equal to the length of the extrusion boss 751. When the moving seat 25 drives the exhaust heat dissipation device 5 and the direction-changing device 7 to move in a certain direction, such as to the left, when it moves to the leftmost end, the extrusion block 75 will be pushed by the reset rod 12 on the left side, so that it moves to the right in the sliding hole 77. In the process of the extrusion block 75 moving to the right, the extrusion boss 751 on the left side thereof will gradually slide and disengage from the root of the bracket plate 711 and enter the air avoidance hole 79 on the left side. At this time, the bracket plate 711 on the left side will be pushed by the reset spring 76 together with the large gear 73 and the transmission gear 74 installed thereon to disengage from the rack 8 and the pinion 72 respectively. At the same time, during the movement of the extrusion block 75 to the right, the extrusion boss 751 on the right side will press against the right bracket plate 711 and gradually push the bracket plate 711 outward, so that the large gear 73 and the transmission gear 74 on it are respectively engaged with the rack 8 and the pinion 72. During this process, the moving seat 25 moves to the far left, touching the control switch 24, and the moving seat 25 starts to move to the right. When moving, the large gear 73, the transmission gear 74 and the pinion 72 will be driven by the rack 8 to rotate, and the exhaust heat dissipation device 5 and the changing device 7 on the right side start to work, cleaning the slide rail protection plate 22 of the right moving seat 25 until they touch the control switch 24 and the reset rod 12 on the right side, and the cycle is repeated in sequence.

[0043] Working principle: When in use, the moving seat 25 drives the exhaust heat dissipation device 5 and the direction-changing device 7 to move in a certain direction. For example, when moving to the left, the extrusion block 75 will be pushed by the reset rod 12 on the left, so that it moves to the right in the sliding hole 77. In the process of the extrusion block 75 moving to the right, the extrusion boss 751 on the left side thereof will gradually slide and detach from the root of the bracket plate 711 and enter the air avoidance hole 79 on the left side. At this time, the bracket plate 711 on the left side will be pushed by the reset spring 76 together with the large gear 73 and the transmission gear 74 installed thereon to detach from the rack 8 and the small gear 72 respectively. At the same time, in the process of the extrusion block 75 moving to the right, the extrusion boss 751 on the right side thereof will be pushed by the reset spring 76 to detach from the rack 8 and the small gear 72 respectively. 751 will press against the right side bracket plate 711 and gradually push the bracket plate 711 outward, so that the large gear 73 and the transmission gear 74 on it are respectively meshed with the rack 8 and the small gear 72. During this process, the movable seat 25 moves to the leftmost side, triggering the control switch 24, and the movable seat 25 starts to move to the right. When moving, the large gear 73, the transmission gear 74 and the small gear 72 will be driven by the rack 8 to rotate, and the exhaust heat dissipation device 5 and the changing device 7 on the right side start to work, cleaning the slide rail protection plate 22 of the right movable seat 25 until they touch the control switch 24 and the reset rod 12 on the right side, and then start the circular movement and cleaning the plate surface according to the above actions.

[0044] Based on the above, the present invention can discharge a large amount of heat generated by the radar system in time to help dissipate heat when the radar system is working at full power for a long time through the coordinated use of the exhaust heat dissipation device and the changing direction device; the exhausted hot air can blow the cleaning dial to rotate to clean up the dust, sand and gravel and other particles caused by wind or construction on the slide rail protection plate, and make the surface of the slide rail protection plate warm up, so as to promote the evaporation of moisture in the dust or particles, make them dry, and will not adhere to the cleaning brush; the set changing direction device can start the exhaust heat dissipation device and the cleaning dial in this direction when the deformation radar moves to the left or right direction, so as to make the cleaning process more efficient.
