When the telescopic shell 2 moves downward along the fixed shell 1, the sealing arc plate 47 automatically swings and opens the surveying cavity 39. At this time, the surveying equipment 34 extends out of the surveying cavity 39 and surveys the surrounding surface.

[0022] In this embodiment: the surveying equipment for space planning is mainly divided into two parts: a fixed housing 1 and a telescopic housing 2. When the equipment is in use, the equipment is first placed on the ground, and then the multiple groups of cylinders 7 are started through the control panel 9 and the length of the supporting legs 8 are adjusted to keep the equipment in a horizontal state. Then the telescopic housing 2 is manually slid downward along the fixed housing 1 through the handle 11. When the telescopic housing 2 moves downward along the telescopic cavity 3, the threaded rod 49 drives the linkage gear 50 to rotate clockwise under the drive of the threaded sleeve 52. Driven by the linkage gear 50, the double gear ring 41 rotates counterclockwise, and at this time, the swing gear 46 drives the sealing arc plate 47 to rotate counterclockwise and open the survey cavity 39. Then the drive motor 19 and the rotating motor 37 are started. When the drive motor 19 drives the meshing ring 16 to rotate, the upper meshing arm 30 synchronously drives the connecting frame 31 to move when it moves along the track 13. When the sliding sleeve 29 moves along the track 13, the second moving platform 25 will also make the same movement relative to the support frame 12, and the equipment compartment 28 will make a square reciprocating motion relative to the support frame 12. When the rotating motor 37 drives the special-shaped gear 38 to rotate, the special-shaped gear 38 will drive the driven gear 36 and the rotating plate 33 to rotate intermittently, so as to perform multiple and cyclic surveys of the surrounding terrain through the survey equipment 34. After the survey operation is completed, the telescopic housing 2 is manually moved upward along the telescopic cavity 3 through the handle 11, and the threaded rod 49 drives the linkage gear 50 to rotate counterclockwise under the drive of the threaded sleeve 52. Driven by the linkage gear 50, the double gear ring 41 rotates clockwise, and the swing gear 46 drives the sealing arc plate 47 to rotate clockwise and close the survey cavity 39.

[0028] In this embodiment: when the drive motor 19 drives the meshing ring 16 to rotate, the upper meshing arm 30 drives the connecting frame 31 to move synchronously when moving along the track 13. When the sliding sleeve 29 moves along the track 13, the second motion platform 25 will also make the same movement relative to the support frame 12, and its trajectory is also a square. Assume that the adjacent sides of the track 13 are A and B, and A is perpendicular to the direction of the first trapezoidal rail 23. When the sliding sleeve 29 moves along the A side of the track 13, the connecting frame 31 drives the second motion platform 25 to slide along the second trapezoidal rail 26, and the first motion platform 22 remains stationary. When the sliding sleeve 29 moves along the B side of the track 13, the first motion platform 22 slides along the first trapezoidal slide 24, and the second motion platform 25 remains stationary relative to the first motion platform 22.

[0029] See attached Figure 2 A rotating column 35 is fixedly provided at the bottom of the rotating plate 33, and the rotating column 35 passes through the top of the equipment bin 28.

During the surveying operation, in order to drive the rotating plate 33 to rotate intermittently, so as to measure the surrounding environment multiple times at 360 degrees, a driven gear 36 and a special-shaped gear 38 that cooperate with each other are designed.

[0031] See attached Figure 7 -Attached Figure 8 An annular hanging plate 40 is fixedly arranged on the top inner wall of the telescopic shell 2, and a double gear ring 41 is movably installed between the annular hanging plate 40 and the top inner wall of the telescopic shell 2, and the double gear ring 41 includes an inner gear ring 42 and an outer gear ring 43; a plurality of sets of swing gears 46 meshing with the inner gear ring 42 are also movably installed on the annular hanging plate 40, and a sealing arc plate 47 is fixedly connected to the middle part of the swing gear 46; symmetrical ring rails 44 are arranged on the upper and lower sides of the double gear ring 41, and annular grooves 45 cooperating with them are also opened on the annular hanging plate 40 and the inner wall of the telescopic shell 2.

[0032] In this embodiment, in order to ensure that the double gear ring 41 can rotate freely relative to the annular hanging plate 40 and further improve its stability during rotation, a ring rail 44 and annular groove 45 structure that cooperate with each other are designed.

[0033] See attached Figure 1 and attached Fig. 9 Three groups of support bins 6 are arranged at the bottom of the fixed shell 1, and a cylinder 7 is installed in the support bin 6. A conical support leg 8 facing downward is installed at the output end of the cylinder 7. A sensor 10 is also installed at the bottom of the fixed shell 1.

[0034] In this embodiment, when the site is uneven during operation, the length of the support legs 8 can be adjusted by multiple independent cylinders 7, so that the device always remains horizontal and the survey accuracy is further improved. In order to monitor the horizontal state of the device in real time, a sensor 10 is designed.

[0035] See attached Figure 7 -Attached Fig. 9 A plurality of groups of convex plates 48 are fixedly provided on the outer side of the annular hanging plate 40, a threaded rod 49 is movably installed on the convex plate 48, and a linkage gear 50 meshing with the outer gear ring 43 is installed on the top of the threaded rod 49; a plurality of groups of fixed plates 51 are fixedly provided on the inner wall of the fixed shell 1, and a threaded sleeve 52 meshing with the threaded rod 49 is provided in the middle of the fixed plate 51.

[0036] In this embodiment: when the telescopic housing 2 moves downward along the telescopic cavity 3, driven by the threaded sleeve 52, the threaded rod 49 drives the linkage gear 50 to rotate clockwise. Driven by the linkage gear 50, the double gear ring 41 rotates counterclockwise, and the swing gear 46 drives the sealing arc plate 47 to rotate counterclockwise and open the survey cavity 39. When the telescopic housing 2 moves upward along the telescopic cavity 3, driven by the threaded sleeve 52, the threaded rod 49 drives the linkage gear 50 to rotate counterclockwise. Driven by the linkage gear 50, the double gear ring 41 rotates clockwise, and the swing gear 46 drives the sealing arc plate 47 to rotate clockwise and close the survey cavity 39.

[0037] See attached Figure 2 and attached Figure 7 A telescopic cavity 3 is provided inside the outer wall of the fixed shell 1, a limiting boss 4 is provided inside the telescopic cavity 3, and a limiting bottom plate 5 cooperating with the limiting boss 4 is fixedly provided at the bottom of the telescopic shell 2.

[0038] In this embodiment, in order to ensure that the telescopic housing 2 slides along the fixed housing 1, so as to store the surveying equipment 34, a telescopic cavity 3 is designed. When the telescopic housing 2 moves along the fixed housing 1, in order to limit its position, a mutually cooperating limiting boss 4 and limiting bottom plate 5 are designed.

[0039] See attached Figure 1 and attached Fig. 9 A control panel 9 is arranged on the outer wall of the fixed shell 1 , and a symmetrical handle 11 is also fixedly arranged on the outer wall of the telescopic shell 2 .

Then the telescopic housing 2 is manually slid downward along the fixed housing 1 through the handle 11. When the telescopic housing 2 moves downward along the telescopic cavity 3, the threaded rod 49 drives the linkage gear 50 to rotate clockwise under the drive of the threaded sleeve 52. Driven by the linkage gear 50, the double gear ring 41 rotates counterclockwise, and at this time the swing gear 46 drives the sealing arc plate 47 to rotate counterclockwise and open the survey cavity 39. Then the drive motor 19 and the rotating motor 37 are started. When the drive motor 19 drives the meshing ring 16 to rotate, the upper meshing arm 30 drives the connecting frame 31 to move synchronously when it moves along the track 13. When the sliding sleeve 29 moves along the track 13, the second motion platform 25 also makes the same movement relative to the support frame 12, and at this time the equipment compartment 28 makes a square reciprocating motion relative to the support frame 12. When the rotating motor 37 drives the special-shaped gear 38 to rotate, the special-shaped gear 38 drives the driven gear 36 and the rotating plate 33 to rotate intermittently, thereby performing multiple, cyclic surveys of the surrounding terrain through the surveying equipment 34. After the surveying operation is completed, the telescopic housing 2 is manually moved upward along the telescopic cavity 3 through the handle 11, and the threaded rod 49 drives the linkage gear 50 to rotate counterclockwise under the drive of the threaded sleeve 52. Driven by the linkage gear 50, the double gear ring 41 rotates clockwise, and at this time the swing gear 46 drives the sealing arc plate 47 to rotate clockwise and close the survey cavity 39.
