Description

Technical Field

[0001] The utility model relates to the technical field of land resource survey, in particular to a land slope measuring device for land resource survey. Background Art

[0002] Land and resources are the material basis for the survival of a country and its residents. They are a material entity composed of natural resources and socio-economic resources. Land and resources in a narrow sense only include natural resources such as land, rivers, lakes, seas, minerals, organisms, and climate. Land and resources in a broad sense also include population resources and socio-economic resources. During the land and resources survey, it is necessary to measure the land area, and during the construction process, the land slope measurement operation must be guaranteed in real time.

[0003] A land slope measuring device for land resources survey described in announcement number CN220288615U includes a support base and a support top plate, the top four corners of the support base are evenly provided with fixed support columns, the bottom four corners of the support top plate are evenly hinged with lifting support columns extending into the fixed support columns, a spherical hinge is provided between the lifting support column and the support top plate, the bottom of the support top plate is provided with a first slope observation plate in the horizontal direction and a second slope observation plate in the vertical direction, the bottom of the support top plate is provided with a first steel wire rope and a second steel wire rope, and the bottom of the first steel wire rope and the bottom of the second steel wire rope are provided with a first counterweight cone and a second counterweight cone respectively. The advantage of the utility model compared with the prior art is that the device can directly observe the land slope through the upper and lower support plates, the top support plate that can adjust the horizontality cooperates with the angle observation plate and the steel wire rope at the bottom, does not require power supply, can be used at any time, and is suitable for promotion and use.

[0004] Although the above land slope measuring device solves certain problems, it still has the following disadvantages:

[0005] (1) The slope displayed by the slope measuring device is measured by the weighted cone being moved vertically downward under the influence of gravity and being aligned with the scale on the observation plate for reading, so as to measure the slope between the slope and the horizontal plane. However, some slopes are not horizontal planes before and after. When measuring such slopes, the measurement result can only be the absolute slope relative to the horizontal plane, and the relative slope of the slope cannot be measured.

[0006] (2) The measuring device is pushed to move on the inclined plane for measurement. The counterweight will swing during the movement, which is not convenient for measurement. In addition, the measuring device is large in size and not convenient to carry. Utility Model Content

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.

[0035] Embodiment 1:

[0036] like Figures 1 to 4 As shown, this embodiment proposes a land slope measuring device for land resources survey, including a mounting rod 1, a lifting rod 2, a mounting plate 3, a positioning assembly 4, an adjustment assembly 5, a first comparison scale 6, a fixed contact elbow 7, a sliding ring 8, a mounting ring block 9, a second comparison scale 10 and a mounting sleeve 11 fixedly connected to the fixed contact elbow 7.

[0037] Among them, a first comparison scale 6 is set on the outer side of the mounting rod 1, and a sliding ring 8 is sleeved on the outside of the mounting rod 1. The sliding ring 8 is open on the side where the first comparison scale 6 is set, and an arrow is fixedly connected to the upper end of the open opening to indicate the first comparison scale 6. A first positioning bolt 401 is threadedly connected to the outer upper end of the sliding ring 8, and the lower end of the first positioning bolt 401 extends to the inside of the sliding ring 8 and contacts the upper end of the mounting rod 1, and the positioning function between the sliding ring 8 and the mounting rod 1 is achieved through friction. A mounting ring block 9 is fixedly connected to the side of the outside of the sliding ring 8 away from the mounting rod 1, and a lifting rod 2 that can slide up and down is set inside the mounting ring block 9. A second positioning bolt 402 is threadedly connected to the side of the outside of the mounting ring block 9 away from the mounting rod 1, and one end of the second positioning bolt 402 extends to the inside of the mounting ring block 9 and contacts the outer side of the lifting rod 2, and the lifting rod 2 is positioned through friction.

[0038] A downwardly bent L-shaped fixed contact elbow 7 is fixedly connected to the external front end of the mounting rod 1, and a mounting sleeve 11 is fixedly connected to the external side of the fixed contact elbow 7 away from the first comparison scale 6. A laser pen 12 is arranged inside the mounting sleeve 11, and a prism lens is fixedly connected to the rear end of the laser pen 12 to refract the light spot emitted by the laser pen 12 into a horizontal line, which is illuminated on the second comparison scale 10 arranged on the external front side of the lifting rod 2 to mark the scale. The position of the point illuminated by the laser pen 12 and the starting scale at the lowest end of the second comparison scale 10 are equal to the distance relative to the mounting rod 1. A mounting plate 3 is fixedly connected to the rear side of the external lower end of the mounting rod 1, and a turntable 13 is rotatably connected to the side of the mounting plate 3 close to the first comparison scale 6. The turntable 13 has two protrusions in front and behind on the side away from the mounting plate 3, forming a groove in the middle, and a level bubble meter 14 is arranged inside the groove, and the two ends of the level bubble meter 14 are respectively fixedly connected to the sides of the two protrusions close to each other.

[0039] Before measuring the slope, first use the flat road surface before the slope as the reference horizontal plane, rotate the turntable 13 until the bubble of the horizontal bubble meter 14 is centered, then the mounting rod 1 is parallel to the road surface, and also serves as a horizontal reference plane, make the lower end of the fixed contact elbow 7 at the front end of the mounting rod 1 contact a point on the inclined plane, move the sliding ring 8 back and forth to a suitable position, if the slope is gentle, adjust the distance between the sliding ring 8 and the fixed contact elbow 7 to be larger, so as to facilitate the reading of the scale and increase the accuracy of the calculated slope, if the slope is relatively gentle, If the slope is too steep, adjust the distance between the sliding ring 8 and the fixed contact elbow 7 slightly closer to prevent the lower end of the lifting rod 2 from not contacting the inclined surface, until the lower end of the lifting rod 2 contacts the inclined surface and the level bubble meter 14 is in the middle position without moving the turntable 13, read the aligned scales on the first comparison scale 6 and the second comparison scale 10 irradiated by the laser pen on the lifting rod 2, and record the horizontal distance L and vertical distance H between the fixed contact elbow 7 and the point where the lower end of the lifting rod 2 contacts the inclined surface respectively. The slope angle is arctan H L .
