[0029] When the surveying instrument 2 needs to be used, in order to prevent the top of the instrument from colliding with the top of the inner wall of the protective shell 31, a movable top plate 33 is hingedly provided to drive the first electric telescopic rod 337, thereby driving the connecting block 338 to move, thereby driving the second gear plate 339 to move downward, thereby driving the second gear 336 to rotate, thereby driving the first movable plate 334 to rotate, thereby driving the second pull ring 333 to rotate, thereby driving the connecting rope 332 and the first pull ring 331 to rotate, thereby driving the movable top plate 33 to rotate. At this time, the movable top plate 33 is transformed from a horizontal state to a vertical state, so as not to affect the up and down movement of the surveying instrument 2.

[0030] A horizontal plate 34 is fixedly provided between multiple columns 32, and two second mounting blocks 341 are fixedly provided on the top of the horizontal plate 34, and a first guide rod 342 is fixedly provided between the two second mounting blocks 341.

[0031] After the movement of the surveying instrument 2 is completed, in order to ensure its stability, it is necessary to limit the movement of the movable rod 321. When the movable rod 321 moves to a certain position, the reset spring drives the second stopper 348 to move, and then drives the plug-in board 347 to move, so that one end of the plug-in board 347 abuts into the opening groove, and the top of the plug-in board 347 contacts the bottom of the movable rod 321, thus realizing the support of the movable rod 321.

[0032] Two guiding seats 35 are fixedly arranged on the opposite sides of the two protective shells 31. A support column 351 is slidably arranged up and down inside the guiding seat 35.

A clamping groove for cooperating with the clamping block 353 is formed on one side of the guiding seat 35, and the clamping groove penetrates through the inner and outer sides of the guiding seat 35.

[0033] Press the clamping block 353 so that it abuts into the receiving groove. At this time, the support column 351 can be moved downward, and then the clamping block 353 is driven to move. When the clamping block 353 moves to the same height as the clamping groove, the spring telescopic rod 354 drives the clamping block 353 to reset, so as to abut into the clamping groove and realize the limitation of the support column 351.

[0034] A support rod 352 is slidably arranged up and down at the bottom of the support column 351. A support plate 355 is fixedly arranged at the bottom of the support rod 352. A U-shaped plate 36 is fixedly arranged on one side of the support column 351. A screw rod 361 is threadedly connected inside the U-shaped plate 36. A limiting tooth plate 362 is rotatably arranged on one side of the screw rod 361. A limiting tooth groove 363 for cooperating with the limiting tooth plate 362 is formed on one side of the support rod 352. An opening groove for the sliding of the limiting tooth plate 362 is formed on one side of the support column 351. A second guiding rod 365 is fixedly arranged on the side of the limiting tooth plate 362 away from the limiting tooth groove 363, and the second guiding rod 365 is slidably connected to the U-shaped plate 36. A knob 364 is fixedly arranged at one end of the screw rod 361.

[0035] Rotate the knob 364, and then drive the screw rod 361 to rotate, and then drive the limiting tooth plate 362 to move, so that the limiting tooth plate 362 is separated from the limiting tooth groove 363, thus releasing the limitation of the support rod 352.

[0036] A first stopper 312 is fixedly arranged on the inner top of the protective shell 31, and the top of the first stopper 312 contacts the bottom of the movable top plate 33.

[0037] A handle 311 is fixedly arranged on the left side of the protective shell 31.

[0038] A non-slip plate 356 is fixedly arranged at the bottom of the support plate 355, and the material of the non-slip plate 356 is specifically rubber.

[0039] The following steps are involved: S1. Open the top cover: turn the movable top plate 33 from a horizontal state to a vertical state to prevent it from affecting the upward movement of the surveying instrument 2; S2. Open the protective device: move the two protective shells 31 in opposite directions; S3, moving the surveying and mapping equipment upward: moving the surveying and mapping instrument 2 upward; S4. Open the support legs: Open the support assembly to support the equipment; S5. Conduct measurement: After completing the support of the equipment, the geographic information can be surveyed and mapped by the surveying instrument 2.

[0040] Working principle: When the surveying instrument 2 needs to be used, in order to prevent the top of the instrument from colliding with the top of the inner wall of the protective shell 31, a movable top plate 33 is hingedly provided to drive the first electric telescopic rod 337, which in turn drives the connecting block 338 to move, thereby driving the second toothed plate 339 to move downward, thereby driving the second gear 336 to rotate, thereby driving the first movable plate 334 to rotate, thereby driving the second pull ring 333 to rotate, thereby driving the connecting rope 332 and the first pull ring 331 to rotate, thereby driving the movable top plate 33 to rotate. At this time, the movable top plate 33 is changed from a horizontal state to a vertical state, so as not to affect the up and down movement of the surveying instrument 2. At this time, the hand wheel is rotated, thereby driving the bidirectional threaded rod 13 to rotate, thereby driving the first threaded seat 14 to move, thereby driving the two protective shells 31 to move in opposite directions, so that a certain distance is generated between the two protective shells 31. When the protective shell 31 is moved, the first toothed plate 31 will be driven through the protective shell 31. After the first gear 323 is moved, the second bevel gear 327 is driven to rotate, and the first bevel gear 326 meshing with the second bevel gear 327 is driven to rotate, thereby driving the threaded rod 324 to rotate, thereby driving the second threaded seat 325 to move, thereby driving the connecting rod 328 to move, thereby driving the movable rod 321 to move, thereby driving the placement plate 21 to move upward, thereby driving the surveying instrument 2 to move upward until the surveying instrument 2 reaches a height at which it can measure. When the surveying instrument 2 has completed its movement, it is necessary to limit the movable rod 321 to ensure its stability. When the movable rod 321 moves to a certain position, the return spring drives the second stopper 348 to move, thereby driving the plug-in plate 347 to move, thereby causing one end of the plug-in plate 347 to press into the open slot, and the top of the plug-in plate 347 contacts the bottom of the movable rod 321, thereby achieving support for the movable rod 321. Press the card block 353 so that it is inserted into the storage slot. At this time, the support column 351 can be moved downward, thereby driving the card block 353 to move. When the card block 353 moves to the same height as the card slot, the spring telescopic rod 354 drives the card block 353 to reset, so that it is inserted into the card slot, thereby limiting the support column 351.

[0041] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
