Description

Technical Field

[0001] The utility model belongs to the technical field of topographic surveying, and particularly relates to a topographic surveying instrument for land space planning. Background Art

[0002] In the process of land space resource planning, topographic surveying devices are needed for measurement. Among the use of many surveying tools, length measurement devices are required to achieve topographic planning survey through length measurement. Commonly used surveying devices include tape measures and laser rangefinders. However, in the process of topographic surveying, when using a tape measure, the tape measure needs to be tightened, and there is a large measurement error in long-distance measurement. In the process of using a laser rangefinder for measurement, for sloping sites, the measurement results are also inaccurate. For this reason, we propose a topographic surveying instrument for land space planning to make the measurement results more accurate. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a topographic surveying instrument for land space planning. By setting a support component, the device can be placed flat on the ground and the heights of the angle correction component and the measurement component can be adjusted. By setting the angle correction component, the measurement component can always be kept in a horizontal state, greatly improving the accuracy of the measurement results.

[0004] The technical solution adopted by the utility model is specifically as follows:

[0005] A topographic surveying instrument for land space planning, comprising a support component, an angle correction component is arranged on the support component, and a measurement component is arranged on the angle correction component. The support component is used to support the angle correction component and the measurement component. The angle correction component is used to adjust the angle of the measurement component and make it located in a vertical plane. The measurement component completes length measurement, height measurement and angle measurement.

[0006] Preferably, the support component includes a bottom plate, four groups of adjusting legs are arranged at the lower end of the bottom plate, a three-section telescopic leg is arranged in the middle of the upper end of the bottom plate, and a marking cone is arranged at the middle position of the lower end of the bottom plate.

[0007] Preferably, the adjusting leg includes a fixed tube arranged at the bottom of the bottom plate, a telescopic cone is arranged inside the fixed tube, and the fixed tube and the telescopic cone are limited by bolts and nuts.

[0008] Preferably, the three-section telescopic leg includes a first leg, a second leg and a third leg. The second leg is movably arranged to slide up and down inside the first leg, and the third leg slides up and down inside the second leg. And the first leg and the second leg, and the second leg and the third leg are limited by bolts.

[0009] Preferably, the angle correction component includes a first spirit level tube disposed at the top of the third leg and a second spirit level tube disposed above the first spirit level tube, and the first spirit level tube and the second spirit level tube are perpendicular to each other.

[0010] Preferably, the measuring component includes a mounting bracket disposed on the upper surface of the second spirit level tube. The upper end of the mounting bracket is connected to a rotating shaft through a bearing. An installation block is provided on the rotating shaft. A laser rangefinder is installed on the installation block. An angle sensor is further provided on the upper surface of the second spirit level tube. The test shaft of the angle sensor is connected to the rotating shaft. The test origin of the laser rangefinder is located directly above the marking cone.

[0011] The technical effects achieved by the present utility model are as follows:

[0012] In the present utility model, first, the marking cone is aligned with the measurement origin, and then the telescopic cone is inserted into the ground. If the ground is uneven, the lengths of different telescopic cones extended are adjusted and fixed with bolts. By observing the first spirit level tube and the second spirit level tube and judging whether the bottom plate is horizontally placed, finally, the bottom plate is horizontally placed, and further the measuring component is horizontally placed, greatly improving the measurement accuracy. Then, according to the actual measurement needs, the height of the measuring component is adjusted by the three-section telescopic legs to keep the laser rangefinder horizontally placed, and the horizontal distance to an object at a certain height is measured. The elevation angle of the laser rangefinder can also be adjusted to measure the distance to the vertex of an object at a certain height. At this time, the elevation angle of the laser rangefinder is measured by the angle sensor, and finally, by solving the cosine theorem in a triangle, the actual height of an object at a certain height is calculated, so that the device can not only measure the distance on a horizontal ground but also measure the height of an object, with more surveying and mapping scenarios. Moreover, since the test origin of the laser rangefinder is located directly above the marking cone, the surveying and mapping results are more accurate. Description of the Drawings

[0021] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text only describes one or several specific implementation manners of the present utility model, and does not strictly limit the scope of protection specifically claimed by the present utility model.

[0022] As Figures 1-6 shown, a topographic surveying instrument for territorial space planning includes a support assembly 1. An angle correction assembly 2 is provided on the support assembly 1, and a measurement assembly 3 is provided on the angle correction assembly 2. The support assembly 1 is used to support the angle correction assembly 2 and the measurement assembly 3. The angle correction assembly 2 is used to adjust the angle of the measurement assembly 3 and make it located on a vertical plane. The measurement assembly 3 completes length measurement, height measurement, and angle measurement.

[0023] In the present utility model, by providing the support assembly 1, the device can be placed flat on the ground and the heights of the angle correction assembly 2 and the measurement assembly 3 can be adjusted. By providing the angle correction assembly 2, the measurement assembly 3 can always be kept in a horizontal state, greatly improving the accuracy of the measurement results.

[0024] The support assembly 1 includes a base plate 11. Four groups of adjusting legs 12 are provided at the lower end of the base plate 11. A three-stage telescopic leg 13 is provided in the middle of the upper end of the base plate 11. A marking cone 14 is provided at the middle position of the lower end of the base plate 11. The adjusting leg 12 includes a fixed tube 121 provided at the bottom of the base plate 11. A telescopic cone 122 is provided inside the fixed tube 121. The fixed tube 121 and the telescopic cone 122 are limited by bolts and nuts. The three-stage telescopic leg 13 includes a first leg 131, a second leg 132, and a third leg 133. The second leg 132 is movably arranged to slide up and down inside the first leg 131. The third leg 133 slides up and down inside the second leg 132. And the first leg 131 and the second leg 132, as well as the second leg 132 and the third leg 133, are limited by bolts.

[0025] In actual use, first align the marking cone 14 with the measurement origin, and then insert the telescopic cone 122 into the ground. If the ground is uneven, adjust the lengths of the different extended telescopic cones 122 and fix them with bolts. By observing the first level tube 21 and the second level tube 22 and judging whether the bottom plate 11 is placed horizontally, finally make the bottom plate 11 placed horizontally, and then make the measurement assembly 3 placed horizontally, greatly improving the measurement accuracy.

[0026] The angle correction assembly 2 includes a first level tube 21 provided at the top of the third leg 133 and a second level tube 22 provided above the first level tube 21. The first level tube 21 and the second level tube 22 are perpendicular to each other.

[0027] In actual use, since the first level tube 21 and the second level tube 22 are perpendicular to each other, it is possible to judge whether the bottom plate 11 and the measurement assembly 3 are placed on a horizontal plane through the first level tube 21 and the second level tube 22, thus greatly improving the measurement accuracy.

[0028] The measurement assembly 3 includes a mounting frame 31 provided on the upper surface of the second level tube 22. The upper end of the mounting frame 31 is connected to a rotating shaft 32 through a bearing. An installation block 33 is provided on the rotating shaft 32, and a laser rangefinder 34 is installed on the installation block 33. An angle sensor 35 is also provided on the upper surface of the second level tube 22. The test shaft of the angle sensor 35 is connected to the rotating shaft 32. The test origin of the laser rangefinder 34 is located directly above the marking cone 14.

[0029] It should be noted that in the present utility model, the laser rangefinder 34 can be kept horizontally placed to complete the measurement of the horizontal distance of an object at a certain height, and the elevation angle of the laser rangefinder 34 can also be adjusted to measure the distance to the vertex of an object at a certain height. At this time, the elevation angle of the laser rangefinder 34 is measured by the angle sensor 35, and finally, by solving the cosine theorem in a triangle, the actual height of an object at a certain height is calculated, so that the device can not only measure the distance on a horizontal ground, but also measure the height of an object, making the surveying and mapping scenarios diverse. Moreover, since the test origin of the laser rangefinder 34 is located directly above the marking cone 14, the surveying and mapping results are more accurate.

[0030] It should be noted that the angle sensor 35 and the laser rangefinder 34 in this embodiment are well-known common knowledge to those skilled in the art and will not be elaborated here.

[0031] Such as Figures 1-6As shown in the figure, the working principle of the present utility model is as follows: First, align the marking cone 14 with the measurement origin, and then insert the telescopic cone 122 into the ground. If the ground is uneven, adjust the lengths of different telescopic cones 122 that extend, and fix them with bolts. By observing the first level tube 21 and the second level tube 22, and judging whether the bottom plate 11 is placed horizontally, finally make the bottom plate 11 horizontally placed, and then make the measurement assembly 3 horizontally placed, greatly improving the measurement accuracy. Then, according to the actual measurement needs, adjust the height of the measurement assembly 3 through the three-section telescopic leg 13, keep the laser rangefinder 34 horizontally placed, and complete the measurement of the horizontal distance to an object at a certain height. It can also adjust the elevation angle of the laser rangefinder 34, so as to measure the distance to the vertex of an object at a certain height. At this time, measure the elevation angle of the laser rangefinder 34 through the angle sensor 35, and finally complete the calculation of the actual height of an object at a certain height by using the cosine theorem in solving triangles, making the device not only able to measure the distance on a horizontal ground, but also able to measure the height of an object, with a wide range of surveying and mapping scenarios. Moreover, since the test origin of the laser rangefinder 34 is directly above the marking cone 14, the surveying and mapping results are more accurate.

[0032] The above is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model are implemented according to the conventional means in this field without special instructions and limitations.
