[0064] In the second embodiment, please refer to Figures 4-9 The installation assembly 11 further comprises a connecting block two 114 slidably connected to the side wall of the supporting leg one 113, and a limiting plate is fixedly connected to the bottom of the supporting leg one 113, and a threaded knob one 115 is threadedly connected to the side wall of the connecting block two 114.

[0067] When the supporting arm 211 is stretched out by the supporting leg one 113, there is a certain gas in the cavity between the supporting arm 211 and the rotating block 212, and the gas pressure in the cavity will decrease when the supporting arm 211 is stretched out, and when the device is inserted into the ground on some soft and uneven ground such as grass and sand, the supporting arm 211 will be subjected to an inward pulling force from the gas, so that the part inserted into the ground will be squeezed inwardly, similar to a clip clamping the ground, increasing the pressure of the contact part with the ground and the static friction, reducing the possibility of the device being knocked down and improving the stability of the device.

[0068] The shielding assembly 21 further comprises a connecting rod 215 rotatably connected to the side wall of the supporting arm 211, and the side wall of the connecting rod 215 away from the supporting arm 211 is slidably connected to the side wall of the baffle 213. When the device is recycled, the supporting leg one 113 is retracted inwardly, the measuring personnel pushes the limiting block 214 upwardly, the limiting block 214 drives the sliding block one 124 to slide at the side wall of the supporting leg one 113, and the supporting arm 211 will slide relative to the sliding block two 222 under the action of the upward pushing force, so that the baffle 213 will rotate under the action of the connecting rod 215 until the included angle between the baffle 213 and the sliding block two 222 is minimum, and meanwhile the limiting block two 223 will press the sliding block two 222 to slide at the inner wall of the sliding groove one 221, press the gas in the sliding groove one 221, and the limiting block two 223 will be clamped in the groove on the surface of the sliding block two 222 to limit the limiting block 214, so as to avoid that, after the device is recycled, the limiting block 214 rebounds under the action of the gas between the supporting arm 211 and the rotating block 212 to affect the recycling of the device, and avoid that the baffle 213 and the supporting leg one 113 are continuously pressed to deform.

[0069] The auxiliary assembly comprises a sliding groove two 312 formed in the inner wall of the limiting block three 311, and a level 313 is slidably connected to the inner wall of the sliding groove two 312.

[0070] Before the device is adjusted, the level 313 is taken out from the limiting block three 311, the level 313 slides at the inner wall of the sliding groove two 312, and after the level 313 is positioned at a suitable position, the device can be adjusted according to the level 313, so as to avoid that, after the device is exposed to the hot environment for a long time, the level 313 is directly irradiated by the sun for a long time, the internal environment temperature of the level 313 is too high, the bubble is deformed, and an error is caused by the deviation.

[0071] One specific application of the embodiment is that: first, the device is placed in a place where measurement is needed, then the supporting leg one 113 is expanded outwardly, and the height position of the device is adjusted by rotating the threaded knob one 115 to control the position of the connecting block two 114 along the supporting leg one 113, and the device is also adjusted by the threaded knob two and the connecting block three 122, and after the device is placed stably, the height is adjusted to a suitable height, and the frame head is roughly horizontal. During the outward expansion of the supporting leg one 113 of the device, the sliding block one 124 drives the supporting arm 211 to slide outwardly, the supporting arm 211 slides at the inner wall of the rotating block 212, and the baffle 213 is driven by the connecting rod 215 to rotate at the inner wall of the rotating block 212 while the supporting arm 211 slides outwardly, the angle of the baffle 213 can be adjusted to shield the light by adjusting the outward expansion degree of the supporting leg one 113, the clear infrared light spot is difficult to observe in summer or when the light around the device is too strong, the observation of the bottom infrared measurement point is affected, and a certain error is caused to the measurement result.

[0072] When the support leg 113 drives the support arm 211 to extend outward, there is a certain gas in the cavity between the support arm 211 and the rotating block 212. When the support arm 211 extends outward, the gas pressure in the cavity will decrease. When the device is inserted into the ground on some soft and uneven ground such as grass and sand, the support leg 113 will be stretched to extract the gas in the cavity, so that the support arm 211 will be subjected to an inward pulling force from the gas, so that the part inserted into the ground will be squeezed inwardly to the inside of the ground, similar to a clip clamping the ground, increasing the pressure of the contact part with the ground, increasing the static friction, reducing the possibility of the device being knocked down, and improving the stability of the device.

[0073] When the device is recycled, the support leg 113 is retracted inwardly, the measuring personnel pushes the limiting block 214 upward, the limiting block 214 drives the sliding block 124 to slide at the side wall of the support leg 113, and the support arm 211 will slide relative to the sliding block 222 under the action of the upward pushing force, so that the baffle 213 will be rotated under the action of the connecting rod 215 until the included angle between the baffle 213 and the sliding block 222 is minimized, and at the same time, the limiting block 223 will squeeze the sliding block 222 to slide at the inner wall of the sliding groove 221, and the limiting block 223 will be clamped in the groove on the surface of the sliding block 222 to limit the limiting block 214, so as to avoid that after the device is recycled, the limiting block 214 is rebounded under the action of the gas between the support arm 211 and the rotating block 212, which affects the recycling of the device, and avoids that the baffle 213 and the support leg 113 are continuously squeezed to produce deformation.

[0074] Before adjusting the device, the level 313 is taken out of the limiting block 311, the level 313 slides at the inner wall of the sliding groove 312, and after reaching the appropriate position, the device can be adjusted according to the level 313, avoiding that the level 313 is directly irradiated by the sun for a long time in a hot environment for a long time, causing the internal environmental temperature of the level 313 to be too high, the bubble to be deformed, and the error to be generated.

[0075] The preferred embodiments disclosed above are only used to help explain the present application. The preferred embodiments do not describe all the details, and the application is not limited to the specific embodiments described. Obviously, many modifications and changes can be made according to the content of the present application.
