[0001] The present invention relates to the field of surveying technology, and is particularly concerned with equipment for measuring slopes and the like, and in particular to equipment for land and geological surveys. Background Art

[0002] In the process of geological survey, it is often necessary to measure the geological environment to be surveyed. For example, when the top is unobstructed, it is necessary to measure the slope of the ground compared to the horizontal plane. When the top is obstructed (such as a cave), in addition to measuring the slope of the ground, the slope of the top compared to the horizontal plane and the distance between the ground and the top (hereinafter referred to as spatial height) are usually measured.

This leads to large errors when analyzing and evaluating the ground slope, top slope and space height (the three types of measured data are collectively referred to as survey data), which makes the survey results inaccurate and affects subsequent work, highlighting the shortcomings of the existing technology.

The inner support tube 8 is coaxially rotatably connected with a vertical outer support tube 9. The top of the outer support tube 9 is fixed with a horizontal support seat 10, and the support seat 10 is horizontally penetrated by a horizontal through hole 1101 A guide strip 1102 is fixed to the inner wall of the through hole 1101 in the axial direction, and the support seat 10 is rotatably connected to a horizontal and cylindrical upper support tube 12, and a screw barrel 13 is coaxially fixed to the inner wall of the upper support tube 12, and the screw barrel 13 is coaxially threadedly connected to a support rod 14, and a radial guide groove 15 is opened on the outer wall of the support rod 14, and the guide groove 15 is horizontally slidably connected to the guide strip 1102, and vertical holding tubes 16 are fixed to the two axial ends of the support rod 14, and vertical distance measuring sensors 17 are fixed to the upper and lower parts of the holding tubes 16 respectively, and the upper and lower parts of the holding tubes 16 are The distance measuring sensor 17 can measure the distance vertically upward and vertically downward respectively.

The posture of the tripod 1 can be adjusted by adjusting the total length of each main support leg 2, thereby indirectly adjusting the posture of the support rod 14, until the inner support tube 8 is in a vertical state. At this time, the support rod 14 can be rotated in the horizontal plane by toggling the support rod 14, so that the distance sensor 17 can move circumferentially, and the distance sensor 17 can be used to measure the inner circle survey data of the point, that is, a large amount of data is obtained, which is convenient for evaluating and analyzing the ground slope, top slope and space height (the ground slope can be obtained by comparing the difference of the data measured downward at the same time point with the fixed value of the horizontal distance between the distance sensors 17, the top slope can be obtained by comparing the difference of the data measured upward at the same time point with the fixed value of the horizontal distance between the distance sensors 17, and the space height can be obtained by adding the data measured upward and downward at the same time point and the fixed value of the vertical distance between the distance sensors 17 at the upper and lower parts of the holding tube 16).

By repeating this process, the survey data within a certain circular area within the point can be measured, that is, a large-area coverage measurement is performed, thereby greatly increasing the amount of survey data measured, so that the error is smaller when the survey data is evaluated and analyzed later.

The upper support leg 3 and the lower support leg 4 are coaxially threadedly connected by external threads and internal threads, and the outer wall of the lower support leg 4 is fixed with a holding portion 25 protruding outward.
