Description

Technical Field

[0001] The utility model relates to the technical field of surveying and mapping, in particular to a slope measuring device for geographical surveying and mapping. Background Technique

[0002] Surveying and mapping is the measurement and drawing. The surveying and mapping science can study and calculate the geometric positions of ground points, the shape of the earth and the earth's gravity field. Based on this, the natural shape of the earth's surface and the geometric distribution of artificial facilities are measured. The main research object of the surveying and mapping science is the earth and its surface form. In the development process, it has formed branch disciplines such as geodesy, general surveying, photogrammetry, engineering surveying, marine surveying and mapping, and cartography. Just make the measuring surface of the slope measuring device be in full contact with the hypotenuse to be measured, and then rotate the scale rotating wheel until the bubble in the level tube is centered, and read the number pointed by the pointer tip on the scale disk, which is the slope of the inclined plane.

[0003] The patent with the publication number of CN220453238U in the prior art proposes a slope measuring device for geographical surveying and mapping. The measuring device is provided with a bottom plate, and an electric telescopic rod is fixedly installed at the center of the top end of the bottom plate. The top end of the turntable one is rotationally connected to the center of the bottom end of the mounting frame. A rotating and fixing component is arranged on one side of the bottom end of the mounting frame. The rotating and fixing component is connected to an L-shaped insertion rod. One end of the L-shaped insertion rod is fitted and connected to a limit card slot one. An installation groove is opened at the top end of the mounting frame, and a movable seat is arranged in the installation groove.

[0004] Although the above-mentioned measuring device can perform data surveying and mapping on slopes, it is relatively large in volume during use, not convenient for the measuring device to be carried conveniently, and cannot accurately and quickly survey data parameters during measurement. It is necessary to perform slope detection multiple times, and the placement of the surveying and mapping equipment is also relatively unstable, reducing the use of the surveying and mapping device. In view of the above problems, we propose an improved and upgraded slope measuring device for geographical surveying and mapping. Content of the Utility Model

The outer wall of the main gear 14 is meshed with a gear ring 15, and a connecting shaft 16 is sleeved in the middle of the gear ring 15. A drum 7 is provided in the middle of the connecting shaft 16, and a spirit level 8 is fixedly provided in the middle of the drum 7. An outer wall of the measuring device 1 is fixedly provided with a measuring panel 9, and telescopic rods 13 are arranged inside the measuring panel 9. A limiting plate 10 is arranged at one end of the telescopic rod 13, and an anti-slip pad 11 is arranged on the outer wall of the measuring panel 9.

[0025] Preferably, a handle 2 is arranged inside the measuring device 1. The main gear 14 and the gear ring 15 are both rotatably installed inside the measuring device 1, which is convenient for the gear ring 15 to stably drive the connecting shaft 16 to rotate. An indicating needle 6 is fixedly arranged inside the drum 7. Discs 4 are arranged at both the upper and lower ends of the measuring device 1, and a plurality of scale lines 5 are arranged on the outer walls of the discs 4, which is convenient for the indicating needle 6 to align with the scale lines 5, facilitating the quick measurement of data parameters and convenient for recording. The anti-slip pad 11 is fixedly arranged on the outer wall of the measuring panel 9. Support columns 12 are arranged at the four corners of the outer wall of the measuring panel 9 where the anti-slip pad 11 is located, which is convenient for the measuring panel 9 on the outer wall of the measuring device 1 to be relatively stable when placed, preventing deviation from affecting the data.

[0026] Preferably, a placement groove 18 is fixedly opened inside the measuring panel 9. The telescopic rods 13 are fixedly arranged inside the placement groove 18, and two groups of telescopic rods 13 are provided, which is convenient for telescoping the limiting plates 10 on both sides to increase the contact panel between the measuring panel 9 and the ground.
