Description

As the core component of land resources, land is directly related to the sustainable development of the economy and society, the protection of the ecological environment, and the stability of social order. In land right registration, key information such as the ownership boundary, location, and area of the land plot must be clearly defined to provide legal evidence for property ownership and avoid ownership disputes.

[0034] Before the connecting cylinder 205 moves downward, the connecting cylinder 205 is at the topmost position, at this time the each guide chute 206 on the connecting cylinder 205 is aligned with the each discharge chute 203 on the storage box 201, at this time the white lime powder in the storage box 201 can be automatically conveyed to the corresponding guide chute 206 through each discharge chute 203; when the measuring device is opened for work, during the downward movement of the connecting cylinder 205, the guide chute 206 can be moved away from the storage box 201, at this time the white lime powder in the guide chute 206 can be automatically scattered into the circular mark pressed by the end of the pressing plate 210 through the through slot 212, which can further improve the visibility of the measurement point marking, and ensure that the measurement point can be accurately identified and reused in the subsequent link; at the same time, under the downward movement of the connecting cylinder 205, the top of the connecting cylinder 205 can automatically block the discharge chute 203 to prevent continuous discharge of white lime powder.

[0035] And during the downward movement of the connecting cylinder 205, the first steel wire rope 213 can be automatically pulled, at this time under the pulling action of the first steel wire rope 213, the active shaft 215 can be driven to rotate automatically through the coil 214, the first gear 220 can be driven to rotate by the active shaft 215, and the first gear 220 can drive the corresponding driven shaft 222 to rotate simultaneously through each meshing second gear 221, under the rotating action of each driven shaft 222, each reinforcing rod 223 can be automatically inserted into the soil, further improving the stability of the positioning work of the measuring device, avoiding the problem that the measuring device cannot work normally due to shaking or even falling of the device caused by strong wind interference during the work of the measuring device.

[0036] After the two installation boxes 1 are positioned and fixed through the above operation, the staff only needs to pull the rings 20 on both sides of the adjusting rod 4, and the second steel wire rope 19 can drive the clamping blocks 21 on both sides to move out of the clamping grooves 18 in the sleeves 3, and then the adjusting rod 4 can move up and down or rotate in the sleeve 3, so that the height and rotation angle of the fixed frame 5 or the fixed plate 10 can be conveniently adjusted. After the fixed frame 5 or the fixed plate 10 is adjusted to the appropriate height and angle, the staff can release the ring 20, and at this time, under the elastic action of the third spring 22, the clamping block 21 can be automatically clamped into the adjacent clamping groove 18, thereby stably supporting the fixed frame 5 or the fixed plate 10, and ensuring the stability of the subsequent measurement work.

[0037] After the fixed frame 5 and the fixed plate 10 are adjusted to the appropriate height and angle, the infrared laser emitted by the laser emitter 7 of the laser range finder 6 can stably irradiate on the second reflecting plate 17 in the middle of the fixed plate 10, and the reflected laser is received by the laser receiver 8. The laser range finder 6 can accurately measure the length of the land boundary; during the height and angle adjustment of the fixed frame 5, the laser range finder 6 can be driven to move synchronously, so that under the joint action of the first reflecting plate 16 on the upper end of the two side plates 14, the reflection range of the laser can be increased, and the staff can conveniently and accurately observe the irradiation position of the laser, so that the staff can conveniently and accurately irradiate the laser on the second reflecting plate 17.

[0038] After the measurement work is completed, the connecting cylinder 205 can be driven upward by the electric push rod 204 to reset, at this time, the center rod 207 and the supporting rod 208 also move upward to reset, and the sliding block 209 can drive the pressing plate 210 to rotate to reset and close the through slot 212; at the same time, after the first steel wire rope 213 loses the pulling force, the driving shaft 215 on the coil 214 also loses the pulling force, at this time, under the elastic action of the first spring 219 in the connecting groove 218, the reinforcing rod 223 can be automatically reversed and moved to the storage groove 217 for resetting, and the reinforcing rod 223 can drive the second gear 221 to reverse through the driven shaft 222, thereby driving the driving shaft 215 to reverse through the first gear 220, and the coil 214 can automatically wind the first steel wire rope 213, ensuring the stability of the subsequent repeated work state.

[0039] Subsequently, the staff can splice the two installation boxes 1, by inserting the positioning rod 23 on one installation box 1 into the positioning frame 25 on the other installation box 1, and during the insertion of the positioning rod 23, the inclined surface of the splicing block 27 can be contacted and the splicing block 27 is automatically pushed upward until the splicing groove 24 on the positioning rod 23 moves below the splicing block 27, at which time the splicing block 27 is automatically moved downward under the elastic action of the fourth spring 26 and is clamped into the splicing groove 24, and the positioning rod 23 and the positioning frame 25 can conveniently splice and fix the two installation boxes 1; and during the splicing of the two installation boxes 1, the first plug rod 30 on the two installation boxes 1 pushes each other, at which time the first plug rod 30 moves to the first gas storage pipe 28, thereby the first piston 29 is synchronously moved, and similarly, under the action of the gas pressure, the second plug rod 35 is automatically moved downward by the second piston 34, and the device as a whole can be lifted by the universal wheel 36, at which time the device as a whole can be conveniently moved by the universal wheels 36.

[0040] Then the staff can push the side plates 14 on both sides of the fixed plate 10 to rotate to the fixed frame 5, and clamp to both sides of the fixed frame 5, and hold the connecting head 902 to rotate the threaded rod 901 on the fixed frame 5, until the threaded rod 901 is threaded into the threaded hole 15 on the side plate 14, completing the clamping and fixing of the side plate 14, at which time under the combined action of the side plate 14 and the fixed plate 10, the fixed frame 5 can conveniently and stably protect the laser range finder 6 in all directions, effectively avoiding the problem that the laser range finder 6 is damaged by external environment during idle and transfer movement.

[0041] At the same time, during the connection of the side plate 14 and the fixed frame 5, the magnetic frame 906 can be moved away from the first sealing frame 903 by the connecting rod 907, at which time the magnetic frame 906 can push the mesh frame 908 and the second sealing frame 909 to move synchronously, and the mesh frame 908 completes the extension work, and the laser range finder 6 in the sealed space can be stably dehumidified and protected by the internal desiccant, avoiding the problem that the internal electrical components of the laser range finder 6 are damaged due to moisture during long-term storage.

[0042] When the side plate 14 is separated from the fixed frame 5, the laser range finder 6 starts to work, under the elastic action of the second spring 904, the magnetic frame 906 can be driven to reset through the adapter plate 905, and then the net frame 908 and the second sealing frame 909 can be driven to reset, at this time, under the joint action of the first sealing frame 903 and the second sealing frame 909, the net frame 908 can be automatically sealed, avoiding that the drying agent is exposed to the outdoor environment for a long time, causing the drying agent to be damp and invalid; when it is necessary to replace the drying agent, the staff only needs to pull the second sealing frame 909 to make it move away from the first sealing frame 903, so as to drive the net frame 908 to move away from the magnetic frame 906, then through the feeding groove 910, the replacement work of the drying agent can be conveniently completed, and after the replacement is completed, the net frame 908 is only needed to be inserted into the magnetic frame 906 again.

[0043] The above only is the preferred embodiment of the present application, and does not limit the present application, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
