Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of slope measurement, in particular to a height measuring device suitable for slopes. Background Art
[0002] Slope refers to artificial slopes formed by excavation or filling construction of construction projects and municipal projects in and around the construction site, and natural slopes that have an adverse effect on the safety or stability of buildings (structures). According to the cause, it can be divided into artificial slopes and natural slopes. In the early stage of engineering construction, geological disaster assessment is usually carried out to have an overall understanding of the geological disasters that may occur or existing geological disasters in the construction process of the construction route, and then the disaster points proposed in the geological disaster assessment report are pre-treated according to the suggestions or specific treatment is carried out during the construction process. Slopes are the most common field survey objects, and the basic attribute height is mostly determined by estimation, with poor accuracy, which leads to a certain impact on its stability evaluation. The instrument can accurately measure the height of the slope, so as to propose a better solution.
[0003] After searching, it was found that the Chinese patent with application number 202320195013.3 discloses a height measuring device. By turning on the switch, the first laser light and the second laser light are irradiated with lasers, and the first rotating shaft and the second rotating shaft are rotated at the same time, so that the first laser light is irradiated on the top of the measured building, and the locking bolt is screwed downward to fix the first rotating shaft, and the angle b of the laser passing through the angle scale is read at this time, and the second rotating shaft is rotated so that the second laser light is irradiated on the bottom of the measured building and is within the length range of the tape measure, and the angle a of the angle scale is recorded at this time, and the height H of the measured building irradiated by the second laser light is measured using a tape measure. Using the trigonometric function tan a=H / H1, the horizontal distance H1 between the first laser light and the measured building can be calculated. The angle b and the horizontal distance H1 are known, and the height F of the measured building can be calculated by tan b=F / H1, without using a tape measure to measure the distance between the device and the building.
[0004] The above technology uses a tape measure to measure the height of the second laser light shining on the measured building, but because the slope has a certain angle, the horizontal height cannot be directly measured. Even if the slope is almost vertical to the ground, it will cause a certain error, which will lead to inaccurate measurement data. At the same time, the device is large in size, and the calculation still needs to be done manually. The device is not completely suitable for use in engineering geological surveying and mapping.

[0036] In the specific implementation process, Figure 1 As shown, it includes a metal shell 1, a battery 2, a power switch 3, a laser lamp 4, a 1 / 4 metal circular plate 5, a protractor 501, a charging port 6, a calculator 7, a tape measure outlet 8, a tape measure storage tray 801, a level 9 and a hinged structure 10. The height measuring device is an instrument for measuring the height of a slope, which is a metal box that is approximately a cube. After opening, there is a battery 2 on the same plane as the calculator 7, a tape measure storage tray 801 and a tape measure outlet 8 at the bottom of the simple calculator 7, a 1 / 4 metal circular plate 5 with a scale at the vertical position between the calculator 7 and the battery, and a protractor 501 and a laser lamp 4 on the 1 / 4 metal circular plate 5; the laser lamp 4 can rotate, and preferably, the laser lamp 4 rotates vertically.
[0037] refer to Figure 1 When using the height measuring device, pay attention to whether the level 9 is in a horizontal state. When a tilt occurs, it can be adjusted to a horizontal position through correction.
[0038] refer to Figure 1 A protractor 501 is provided on the surface of the 1 / 4 metal circular plate 5. Through the protractor 501, the user can clearly read the angle formed by the laser and the horizontal plane, thereby facilitating the user's calculation.
