Rotating motor 3 for driving total station to rotate is fixed in placing box 1, and vertical board 4 is fixed on the side wall of protection box 2. The bottom of vertical board 4 is provided with connecting groove.

[0030] ​The turnover mechanism 5 comprises a connecting assembly 51 and a turnover assembly 52. The connecting assembly 51 comprises an annular plate 511, a sliding block 512, a connecting block 513 and a rotating rod 514. The annular plate 511 is fixedly arranged through the side wall of the placing box 1, and the sliding block 512 is slidingly fitted in the annular plate 511. The connecting block 513 is matched with the connecting groove, and the connecting block 513 is fixed with the sliding block 512. The rotating rod 514 is rotatably arranged through the connecting block 513, and the rotating rod 514 is fixedly arranged through the side walls on both sides of the connecting groove.

[0031] The turnover assembly 52 is used to drive the vertical plate 4 to turn over when the sliding block 512 is close to the top of the placing box 1 and is lifted. The turnover assembly 52 is arranged in two groups and is symmetrically distributed about the middle part of the vertical plate 4. Each group of turnover assemblies 52 comprises an annular frame 521, a rack 522 and a turnover gear 523. The annular frame 521 is fixed to the side of the annular plate 511 away from the placing box 1. The rack 522 is fixed to the inner side wall of the annular frame 521 close to the top of the annular frame 521. The turnover gear 523 is fixedly sleeved on the rotating rod 514 and is engaged with the rack 522. The two annular frames 521 are fixed with the limiting plate 7.

[0032] The lifting mechanism 6 is arranged in the placing box 1 and is used to drive the sliding block 512 to lift. The lifting mechanism 6 comprises a mounting frame 61, a lifting motor 62, a driving gear 63, a threaded rod 64 and a driven gear 65. The mounting frame 61 is fixed in the placing box 1. The lifting motor 62 is fixed on the mounting frame 61. The driving gear 63 is fixedly sleeved on the output end of the lifting motor 62. The threaded rod 64 is threadedly connected through the top of the sliding block 512 and is rotatably arranged between the inner top wall and the inner bottom wall of the placing box 1. The driven gear 65 is fixedly sleeved on the threaded rod 64 and is engaged with the driving gear 63.

[0033] When the rotating motor 3 works, the driving gear 63 is driven to rotate, so that the driven gear 65 engaged with the driving gear 63 and the threaded rod 64 fixed with the driven gear 65 are also rotated, so that the sliding block 512 connected with the threaded rod 64, the connecting block 513 fixed with the sliding block 512, the rotating rod 514 rotatably connected with the connecting block 513, the vertical plate 4 connected with the rotating rod 514, the turnover gear 523 connected with the rotating rod 514 and the protective box 2 fixed with the vertical plate 4 are all raised. In this process, when the sliding block 512 approaches the top of the placing box 1, the turnover gear 523 will engage with the rack 522, so that the rotating rod 514 fixed with the turnover gear 523, the vertical plate 4 fixed with the rotating rod 514 and the protective box 2 fixed with the vertical plate 4 are all turned over until they are away from the total station. At this time, when the rotating motor 3 works, the total station is driven to rotate, so that the surrounding can be observed at multiple angles. After the total station is used, the rotating motor 3 is driven to rotate reversely, so that the driving gear 63 is reversely rotated, the driven gear 65 engaged with the driving gear 63 and the threaded rod 64 fixed with the driven gear 65 are also reversely rotated, so that the sliding block 512, the connecting block 513, the rotating rod 514 and the vertical plate 4 are all lowered, and the rack 522 and the gear are changed from the engaged state to the non-engaged state. In this process, first, the vertical plate 4 drives the protective box 2 to reversely turn over and reset, and finally the vertical plate 4 drives the protective box 2 to continue to descend until the bottom of the protective box 2 is attached to the top of the placing box 1. At this time, the protective box 2 covers the total station in the protective box 2 and protects the total station. In the process of observation of the total station, no other manual operation is required, so that the observation field of view of the total station is ensured, and the use of the device is facilitated.

[0034] The top of the annular plate 511 is fixed with a sealing plate 8, and the vertical plate 4 has an L-shaped cross section. The vertical plate 4 is provided with a sealing groove 9 which is inserted and matched with the sealing plate 8. The sealing plate 8 and the sealing groove 9 reduce the probability of rain entering the placing box 1 through the annular plate 511 when the placing box 1 and the protective box 2 are attached.

[0035] The side of the limiting plate 7 close to the placing box 1 is movably provided with a plurality of rolling balls 10 which are in rolling connection with the vertical section of the vertical plate 4. The rolling balls 10 reduce the friction between the vertical plate 4 and the limiting plate 7 when the vertical plate 4 moves.

[0036] The placing box 1 is provided with heat dissipation fins 11 fixed with the side wall of the placing box 1. The heat dissipation fins 11 improve the speed of heat dissipation in the placing box 1.

[0037] The top of the placing box 1 is fixed with an annular blocking strip 12, and the outer side of the annular blocking strip 12 is fixed with an annular sealing strip 13 which abuts against the inner side wall of the protective box 2. The annular blocking strip 12 and the annular sealing strip 13 reduce the probability of rain entering the protective box 2 through the gap between the placing box 1 and the protective box 2.
