When the falling rock collides with the outer side of the protective sleeve 5, the spring 82 and the elastic protective pad 53 buffer the collision potential energy, and the protection of the measuring reflector body 3 is completed, and the laser reflected by the measuring reflector body 3 passes through the connecting cavity 92, the adapter port 52 is emitted, and the reflected laser is reflected back and received in the same way, and then the fan 62 in the heat dissipation and air supply component 6 is started to draw air from the external environment, the external air is filtered through the filter sponge 65, and part of the moisture is adsorbed in the filter sponge 65, and the air after filtration and preliminary dehumidification is further sucked into the dehumidification component 7, the moisture is absorbed by the hygroscopic material, and the clean and dry ambient air is sucked into the sleeve body 51 and blown to both sides of the measuring reflector body 3 to complete air cooling.

As the rotating rod 73 rotates, the connected stirring plate 74 is driven to rotate and stir in the storage sleeve 71, so that the internal hygroscopic filler is stirred and dispersed, completing quick disturbance.

[0034] First, by cooperating with the rotating rod 73 and the stirring plate 74 in the dehumidification component 7, in the actual process of dissipating heat and inhaling air, the rotating rod 73 can be manually rotated as needed, and the stirring plate 74 can be driven to rotate, thereby disturbing and dispersing the hygroscopic material in the storage sleeve 71 to avoid accumulation, thereby further improving the dehumidification effect of the inhaled air.

[0035] Embodiment 3: After the measurement is completed, the locking ring 83 is manually screwed upward to allow the spring 82 to elastically reset and push the sleeve body 51 upward. As the sleeve body 51 moves upward, the adapter port 52 is driven to move upward, so that the adapter port 52 is offset from the connecting cavity 92 and the connecting cavity 92 is sealed, thereby sealing the emitting end of the measuring reflector body 3 to complete further sealing protection.

[0036] Firstly, by reusing the elastic sleeve connection of the buffer positioning assembly 8 and the protective sleeve 5, the position of the sleeve body 51 can be automatically adjusted while the locking ring 83 is screwed up, thereby changing the position of the adapter port 52, and by staggering the adapter port 52 and the connecting cavity 92, the connecting cavity 92 is sealed, thereby quickly closing the emitting end area of ​​the measuring reflector body 3, realizing quick protection when not in use, simple operation, and good use effect.

[0042] The buffer-type positioning assembly 8 realizes the elastic sleeve connection of the protective sleeve 5, and cooperates with the elasticity of the spring 82 to provide collision buffering. At the same time, the elasticity of the spring 82 is utilized, combined with the locking limit of the locking ring 83, to conveniently limit the position of the protective sleeve 5, change the position of the adapter port 52, and switch the sealing and opening states of the emitting end of the measuring reflector body 3. The buffer-type positioning assembly 8 also provides sleeve connection positioning of the protective sleeve 5 to limit the direction of the adapter port 52.

[0043] Among them, the guide assembly 9 includes a baffle 91, a connecting cavity 92 and an oblique air guide port 93.

[0047] The inner diameters of the adapter port 52 and the connecting cavity 92 are the same, and the connecting cavity 92 is located on the moving path of the adapter port 52 .

[0048] By utilizing the position control of the adapter port 52 and the communication cavity 92, the sealing and opening control of the emitting end of the measuring reflector body 3 is achieved.

[0049] The working principle and use process of the present invention are as follows: when in use, the measuring reflector body 3 is sleeved in the mounting assembly 4 and is locked and fixed by the locking bolt 43, and the emitting end of the measuring reflector body 3 is kept facing the connecting cavity 92 of the guiding assembly 9, the protective sleeve 5 is sleeved on the top of the mounting seat 1 and on the outside of the measuring reflector body 3, and the fixed shaft 81 is kept aligned with the circular hole on the top of the sleeve body 51, and the sleeve body 51 is pressed down, and the spring 82 is compressed, so that the adapter 52 on the outer surface of the sleeve body 51 is aligned and connected with the connecting cavity 92, and the sleeve body 51 is rotated.

When the falling rock collides with the outer side of the protection sleeve 5, the spring 82 and the elastic protection pad 53 buffer the collision potential energy, and the protection of the measuring reflector body 3 is completed. The laser reflected by the measuring reflector body 3 is emitted through the connecting cavity 92 and the adapter 52, and the reflected laser is reflected back and received in the same way. Then, the fan 62 in the heat dissipation and air supply component 6 is started to suck air from the outside environment.

The filtered and preliminarily dehumidified air is further The moisture is then sucked into the dehumidification assembly 7, and the moisture is absorbed by the hygroscopic material. The clean and dry ambient air is sucked into the sleeve body 51 and blown to both sides of the measuring reflector body 3 to complete air cooling. After heat exchange, the air enters the connecting cavity 92 along the wind guide oblique port 93 of the guide assembly 9, and the inside of the connecting cavity 92 is purged. At the same time, the emitting end of the measuring reflector body 3 is purged by wind, and the air is blown out through the adapter port 52 to complete clean heat dissipation and self-cleaning of the measuring reflector body 3.
