[0032] Specifically, the wheel 2 is mounted on the wheel hub 9, and the wheel hub 9 is closely connected with the transmission rod 8. When the observation instrument needs to move, the wheel 2 will roll forward, and the ground reaction force exerted on the wheel hub 9 will be transmitted to the vehicle body 1 through the transmission rod 8. This design allows the observation instrument to adapt to the bumps of the ground by rotating the transmission rod 8 when moving, thereby effectively alleviating the deformation of the wheel 2 caused by the uneven ground. At the same time, a rotating block 10 is installed on the vehicle body 1, and a rotating block 2 11 is installed on the wheel hub 9. A spring damper 12 is connected between the two rotating blocks. When the transmission rod 8 is deformed, the spring damper 12 will play a shock-absorbing role, absorbing and dispersing the impact force generated by the ground bumps, thereby effectively protecting the observation module 5 on the top of the vehicle body 1.
[0033] Reference Figure 1 , both sides of the outer wall of the vehicle body 1 are fixedly connected with support components, the support components include a hydraulic push rod 4 and a support base 3, the top of the support base 3 is fixedly connected to the output end of the hydraulic push rod 4, and the outer wall of the hydraulic push rod 4 is fixedly connected to the outer wall of the vehicle body 1;
[0034] Specifically, a support base 3 is provided on the side of the vehicle body 1. When used for observation, the support base 3 can be pushed by the hydraulic push rod 4 so that the support base 3 supports the vehicle body 1, thereby ensuring the stability of the vehicle body 1 during use, which can make the measurement result more accurate.
[0035] Reference Figure 3 and Figure 4 , the inside of the bracket 6 is slidably connected with a slide bar 7, one side of the outer wall of the observation module 5 is fixedly connected to one side of the outer wall of the slide bar 7, a slide groove 13 is opened inside the bracket 6, the outer wall of the slide bar 7 is slidably connected inside the slide groove 13, one side of the inside of the bracket 6 is rotatably connected with a gear 2 18, one side of the outer wall of the slide bar 7 is opened with a tooth groove 14, the gear 2 18 is meshed with the tooth groove 14, one side of the inside of the bracket 6 is rotatably connected with a rotating shaft 17, one side of the outer wall of the rotating shaft 17 is fixedly connected with a gear 16, the gear 16 is meshed with the gear 2 18, one end of the rotating shaft 17 is fixedly connected with a rotating handle 15, and the other side of the outer wall of the rotating shaft 17 is fixedly connected with a ratchet 19, one side of the inside of the bracket 6 is rotatably connected with a pawl 20, the pawl 20 is meshed with the ratchet 19, one side of the outer wall of the pawl 20 is fixedly connected with a pressing handle 22, one side of the outer wall of the pawl 20 is rotatably connected with a spring piece 21, and one side of the spring piece 21 is fixedly connected to the inside of the bracket 6;
[0036] Specifically, first, when the rotating handle 15 is driven, it will drive the rotating shaft 17 to start rotating, and when it rotates, it can drive the gear 16 on one side to rotate synchronously. As the gear 16 rotates, the gear 2 18 also starts to rotate, and the gear 2 18 meshes with the tooth groove 14 on the slide bar 7, so that the slide bar 7 can slide in the slide groove 13 inside the bracket 6, and then the slide bar 7 drives the movement of the observation module 5 to achieve the height adjustment of the observation target. During the rotation of the rotating shaft 17, the ratchet 19 will also rotate. The ratchet 19 is a special gear, and its tooth shape design makes it It can only rotate in one direction. Under the action of the spring 21, the pawl 20 is pressed on the ratchet 19, so that the ratchet 19 will not reverse during rotation. At the same time, the gravity of the slide bar 7 will also affect the rotation direction of the ratchet 19, so that when the ratchet 19 is locked by the pawl 20, the entire mechanism will be in a locked state. At this time, the height of the slide bar 7 and the observation module 5 will be fixed. When it needs to be lowered, the pawl 20 can be controlled to be lifted by pressing the handle 22. When the pawl 20 is lifted, the locked state of the ratchet 19 will be released, and the height of the entire mechanism can be readjusted.
[0037] Working principle: When the observation instrument moves, the wheel 2 is installed on the wheel hub 9 and can be moved by the wheel 2. The force on the wheel hub 9 will be transmitted to the vehicle body 1 through the transmission rod 8, and the rotation of the transmission rod 8 can adapt to the deformation of the wheel 2 caused by the bumpy road surface. The spring damper 12 is connected by the rotating block 10 on the vehicle body 1 and the rotating block 2 11 on the wheel hub 9 to ensure the output direction of the spring damper 12, so that the spring damper 12 can reduce the vibration of the transmission rod 8 deformation, so as to protect the observation module 5 on the top of the vehicle body 1. When the height of the observation module 5 is adjusted, the rotating shaft 17 can be driven to rotate by the rotating handle 15, and the rotating shaft 17 It will drive one side gear 16 to rotate, and gear 16 will be transmitted through gear 2 18, and then gear 2 18 will mesh with the tooth groove 14 on the slide bar 7, driving the slide bar 7 to slide in the slide groove 13 inside the bracket 6, so that the slide bar 7 drives the observation module 5 to adjust the height. When the rotating shaft 17 rotates, the ratchet 19 on the rotating shaft 17 will rotate accordingly, and the pawl 20 can be pressed on the ratchet 19 under the action of the spring 21, and then the movement direction caused by the gravity of the slide bar 7 is combined with the ratchet 19 to be locked by the pawl 20, so that the mechanism can be locked. When it needs to be lowered, the pawl 20 can be controlled to be lifted by pressing the handle 22, so that the mechanism is unlocked.
