[0040] The working principle and use process of the present invention: When in use, fix the limiting connecting plate 1 on the bracket, Figure 1 In the state shown, the first elastic driving member 28 is in a stretched state. At this time, the user is performing geographic information mapping through the surveying instrument 25. When the weather is hot, the cooling fan 35 is powered on to blow air into the interior of the adjustable protective box 31. At this time, the adjustable protective box 31 gathers and guides the airflow, so that the cooling airflow is ejected in the direction of the surveying instrument 25, thereby achieving all-round cooling of the surveying instrument 25, thereby preventing the internal components of the surveying instrument 25 from expanding due to high temperature and affecting the mapping accuracy.

[0041] When the surveying and mapping device accidentally falls over, during the process of the device falling over, the conductive metal ball 211 contacts the conductive metal cylinder 212, causing the height adjustment member 231 to be energized and retracted. At this time, the height adjustment member 231 cooperates with the traction rope 236 to drive the two second limit plates 233 to move closer to each other. At this time, the adjustable locking plate 234 retracts to release the limit fixation of the adjustable protection box 31, so that the adjustable protection box 31 is instantly moved upward under the driving action of the first elastic driving member 28. After moving upward, the adjustable protection box 31 stores the surveying instrument 25 inside it. At this time, the adjustable protection box 31 is limited and braked by the limit brake plate 27.

[0042] When the adjustable protection box 31 moves up to the right position, the movable unlocking plate 37 at the bottom of the adjustable protection box 31 drives the deformable locking plate 245 to tilt so as to release the deformable locking plate 245 from fixing the third limit plate 241. At this time, the third limit plate 241 moves up instantly under the driving action of the third elastic driving member 242. At this time, the air in the piston pump 243 is transferred to the interior of the hollow elastic tube 32 through the air supply hose 244, causing the hollow elastic tube 32 to expand instantly. The expanded hollow elastic tube 32 provides all-round protection for the surveying instrument 25, thereby achieving the goal of the adjustable protection box 31 moving up first, and then triggering the instantaneous inflation of the hollow elastic tube 32 after the adjustable protection box 31 moves up to the target position, so that the hollow elastic tube 32 is instantly inflated and expanded. The adjustable protection box 31 and the hollow elastic tube 32 cooperate with each other to provide sufficient anti-collision protection for the surveying instrument 25.

[0043] When in use, the bottom of the transmission rope 246 passes through the adjustable protective box 31 and extends to the bottom of the adjustable protective box 31. When the user needs to release the protection of the surveying instrument 25, the user first pulls the transmission rope 246 downward to move the third limit plate 241 downward to a state locked by the deformable locking plate 245. At this time, the hollow elastic tube 32 retracts to restore its initial shape. Then, the user pulls the adjustable protective box 31 downward through the fourth limit plate 33 to lock the adjustable locking plate 234 to the adjustable protective box 31, so that the device quickly returns to the attached state. Figure 1 The working status shown;

[0044] Thus, through the mutual cooperation of multiple structures, the surveying and mapping device can automatically raise the adjustable protective box 31 to provide anti-collision protection for the surveying and mapping instrument 25 during an accidental tipping process. Secondly, when the adjustable protective box 31 is moved up to the protection position, the present application can inflate the hollow elastic tube 32 in the adjustable protective box 31 through the linkage cooperation of multiple structures, so that the hollow elastic tube 32 is quickly inflated and expanded. At this time, the inflated hollow elastic tube 32 provides elastic limiting protection for the surveying and mapping instrument 25, further preventing the surveying and mapping instrument 25 from being damaged due to collision, thereby providing sufficient anti-collision protection for the surveying and mapping instrument 25 through the sequential and mutual superposition of two-stage protection. In addition, the present invention has a simple structure, is easy to use, and is worthy of promotion and use.
