[0002] Land is an important foundation for our survival and development. Therefore, it is of great significance to do a good job in land surveying. With the progress of society, science and technology are constantly developing, and the value of land consolidation work is also constantly increasing. Therefore, people's requirements for surveying and mapping technology in land surveying are also constantly increasing. Reasonable spatial planning of the country cannot be separated from accurate land surveying. Land surveying is the use of surveying and remote sensing technology to measure and map the quantity, distribution and topography of various types of land. It includes topographic surveying, cadastral surveying, land leveling surveying, land use status surveying, and reserve resource investigations such as barren mountains and wastelands. The measurement methods used include geodetic surveying, ordinary surveying, aerial photogrammetry, remote sensing technology, and map compilation.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1-6 The utility model provides a vehicle-mounted measuring device for land space planning: comprising a box body 1 and a cover plate 2 hingedly mounted on the top of the box body 1, a lifting mechanism is arranged inside the box body 1, a mounting plate 3 is arranged on the lifting mechanism, a measuring instrument 4 is mounted on the top of the mounting plate 3, a water spraying mechanism and a cleaning mechanism are arranged inside the box body 1, a support frame 5 is fixedly connected to one side of the mounting plate 3, a rack 6 is fixedly connected to the support frame 5, and the lifting mechanism is used to drive the measuring instrument 4 to rise and fall;

[0031] When the measuring instrument 4 is not needed, the driving mechanism drives the mounting plate 3 and the measuring instrument 4 to retract into the box body 1, which can trigger the water spray mechanism to spray cleaning agent onto the lens of the measuring instrument 4. The downward movement of the mounting plate 3 can drive the rack 6 to move downward synchronously. The moving rack 6 can drive the cleaning mechanism to rotate and wipe the lens of the measuring instrument 4 sprayed with the cleaning agent to clean it. In the process of storing the measuring instrument 4 in the box body 1, the dust on the lens of the measuring instrument 4 is automatically cleaned, replacing the traditional manual cleaning. It has a high degree of automation, saves time and effort, and improves the cleanliness of the lens of the measuring instrument 4, thereby improving the accuracy of subsequent measurements by the measuring instrument 4.

[0032] The lifting mechanism includes a driving motor 7 and a guide rod 8, both of which are fixedly mounted at the bottom of the inner wall of the box body 1, the output end of the driving motor 7 is fixedly connected to a threaded rod 9, the mounting plate 3 is threadedly sleeved on the outside of the threaded rod 9, and the mounting plate 3 is movably sleeved on the outside of the guide rod 8.

[0033] The water spraying mechanism comprises a water storage tank 10 and a piston cylinder 11 fixedly mounted on the inner wall of the box body 1, the water storage tank 10 and the piston cylinder 11 are connected through a water inlet pipe, the bottom end of the piston cylinder 11 is fixedly connected with a water outlet pipe 12, the other end of the water outlet pipe 12 is fixedly connected with a nozzle 13, a piston 14 is arranged inside the piston cylinder 11, the top of the piston 14 is fixedly connected with a vertical rod 15, the other end of the vertical rod 15 movably passes through the piston cylinder 11 and is fixedly connected with an elastic telescopic rod 16, a tension spring 17 is arranged between the top of the piston 14 and the top of the inner wall of the piston cylinder 11 and on the outside of the vertical rod 15, and the elastic force system of the elastic telescopic rod 16 The number is greater than the elastic coefficient of the tension spring 17, a one-way valve 18 is provided on the water inlet pipe, and a one-way valve 2 19 is provided on the water outlet pipe 12. Through the setting of the one-way valve 18, the detergent in the water storage tank 10 can flow into the piston cylinder 11 through the water inlet pipe, and cannot flow in the reverse direction. Through the setting of the one-way valve 2 19, the detergent in the piston cylinder 11 can flow to the nozzle 13 through the water outlet pipe 12, and cannot flow in the reverse direction, so that when the piston 14 moves upward, the detergent in the water storage tank 10 is drawn into the piston cylinder 11, and when the piston 14 moves downward, the detergent in the piston cylinder 11 is discharged to the nozzle 13 through the water outlet pipe 12.

[0034] The cleaning mechanism includes a small gear 20 and a large gear 21 rotatably mounted on the inner wall of the box body 1. A cleaning cotton 22 is fixedly connected to one side of the small gear 20. The outer surface of the large gear 21 is meshed with the outer surface of the small gear 20. Through the setting of the cleaning mechanism, during the downward movement of the rack 6, when the rack 6 moves to mesh with the large gear 21, the downward movement of the rack 6 will drive the large gear 21 to rotate, thereby driving the small gear 20 meshing therewith to rotate rapidly, and driving the cleaning cotton 22 to rotate and wipe the lens of the measuring instrument 4 to clean it.

[0035] Mounting ears 23 are provided on both sides of the box body 1, and the mounting ears 23 facilitate the installation of the box body 1 on the vehicle.

[0036] Working principle: First, the measuring device is installed at a suitable position on the vehicle through the mounting ears 23, and a proper amount of detergent is injected into the water tank 10. When the vehicle-mounted measuring device needs to be used, the staff first opens the cover plate 2, and then starts the drive motor 7. The output end of the drive motor 7 rotates clockwise to drive the threaded rod 9 to rotate synchronously, and under the limiting effect of the guide rod 8 on the mounting plate 3, the mounting plate 3 and the measuring instrument 4 are moved upward along the axial direction of the threaded rod 9, and then the measuring instrument 4 can be moved out of the box body 1. At this time, the measuring instrument 4 is exposed outside the box body 1, which is convenient for workers to use the measuring instrument 4 to measure the land;

[0037] During the upward movement of the mounting plate 3, the squeezing of the elastic telescopic rod 16 can be released, the elastic telescopic rod 16 extends upward, and the piston 14 is driven upward by the elastic force of the tension spring 17, so that the detergent in the water storage tank 10 can be pumped into the piston cylinder 11 through the water inlet pipe for standby use;

[0038] When the measuring instrument 4 is exposed to the outside world, the lens of the measuring instrument 4 is prone to absorb dust in the air. Especially when the dust in the measuring environment air is large, a large amount of dust will be absorbed on the lens of the measuring instrument 4. Therefore, after the use of the measuring instrument 4, the lens of the measuring instrument 4 needs to be cleaned to improve the cleanliness of the lens and avoid dust accumulation that affects the accuracy of subsequent measurement data of the measuring instrument 4.

[0039] When the measuring instrument 4 is not needed, the output end of the driving motor 7 rotates counterclockwise, indirectly driving the mounting plate 3 and the measuring instrument 4 to descend and retract them into the box body 1. When the mounting plate 3 moves down to abut against the top of the elastic telescopic rod 16, the lens on the measuring instrument 4 on the top of the mounting plate 3 is just opposite to the position of the spray head 13. When the mounting plate 3 continues to move downward, the elastic telescopic rod 16 will be pressed downward. Since the elastic coefficient of the elastic telescopic rod 16 is greater than the elastic coefficient of the tension spring 17, the vertical rod 15 and the piston 14 are pushed downward synchronously by the elastic telescopic rod 16. During the downward movement of the piston 14 in the piston cylinder 11, the cleaning agent inside the piston cylinder 11 can be transported to the spray head 13 through the water outlet pipe 12, and finally the cleaning agent is sprayed onto the lens of the measuring instrument 4 through the spray head 13.

[0040] After the cleaning agent is sprayed on the lens of the measuring instrument 4, the mounting plate 3 continues to move downward to drive the rack 6 to move downward synchronously. After the rack 6 moves to engage with the large gear 21, the downward movement of the rack 6 will drive the large gear 21 to rotate, thereby driving the small gear 20 engaged with it to rotate rapidly, and driving the cleaning cotton 22 to rotate and wipe the lens of the measuring instrument 4 to clean it.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
