Description

Technical Field

[0001] The utility model relates to the technical field of landslide angle measurement, and specifically relates to a landslide dip angle measurement device. Background Technique

[0002] A landslide refers to the natural phenomenon that the soil or rock mass on a slope is affected by factors such as river scouring, groundwater activity, rainwater soaking, earthquake and artificial slope cutting, and under the action of impact force, it slides down along a certain weak surface or weak zone as a whole or dispersedly along the slope. When carrying out the treatment and prevention work of landslides, it is usually necessary to measure the dip angle of the landslide so that people can predict the occurrence trend of the landslide, provide decision-making support for relevant departments, and thus take appropriate measures to reduce the losses caused by the landslide.

[0003] At present, when measuring the dip angle of a landslide, an angle measuring instrument is usually used. Since the surface of the landslide is scoured by rainwater, rivers, etc., the surface of the landslide is not flat. Therefore, when the angle measuring instrument measures the dip angle, the measured data has a large error. Moreover, when using the angle measuring instrument, it is necessary to manually adjust the horizontal state of the level in the angle measuring instrument, and it is difficult to completely level the level manually, so that the measured data still has a deviation.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0023] See also Figures 1 to 7 In an embodiment of the utility model, a landslide inclination measuring device comprises an L-shaped plate 1, a bottom plate 2 is arranged at the bottom end of the L-shaped plate 1, a rectangular hole 12 is penetrated through the top surface of the L-shaped plate 1, a rotating shaft is fixedly connected between two opposite side surfaces inside the rectangular hole 12, a rotating disk 3 is rotatably connected to the outer wall of the rotating shaft, a scale 31 is printed on both sides of the rotating disk 3, downward-facing pointers 13 are fixedly connected to the outer wall of the rotating shaft at both ends, a counterweight 32 is fixedly connected to the outer wall of the rotating disk 3, and an equidistant mechanism 4 is slidably and rotatably provided on one side of the L-shaped plate 1.

[0024] Specifically, first, closely attach the bottom plate 2 to the slope surface of the landslide. Then, rotate the L-shaped plate 1 until the center line of the pointer 13 coincides with the center line of the counterweight 32. Since the center line of the counterweight 32 is always perpendicular to the horizontal plane under the action of the turntable 3, at this time, the L-shaped plate 1 is perpendicular to the horizontal plane. Then, make the bottom end of the equidistant mechanism 4 abut against the slope surface, and then rotate the L-shaped plate 1 again to form a certain angle between the L-shaped plate 1 and the bottom plate 2. Since the turntable 3 rotates on the outer wall of the rotating shaft and the counterweight 32 is fixed to the outer wall of the turntable 3, the turntable 3 rotates under the action of the counterweight 32, causing an angle to form between the center line of the pointer 13 and the center line of the counterweight 32. Then, move the equidistant mechanism 4 to the other end of the side surface of the L-shaped plate 1. Since the length of the equidistant mechanism 4 is fixed, one side surface of the L-shaped plate 1 can be made parallel to the slope surface. Then, by observing the position of the pointer 13 on the scale one 31, the angle between the center line of the pointer 13 and the center line of the counterweight 32 can be obtained. Then, by calculating (90 degrees minus the angle value between the center line of the pointer 13 and the center line of the counterweight 32), the inclination angle of the landslide slope surface can be obtained. This device can be used for measurement on an uneven slope surface, and the measured value is more accurate than that of an angle measuring instrument.

[0025] Embodiment 1

[0026] As Figure 1-3 shown, in this embodiment, a plurality of spikes 21 are fixedly connected to the bottom surface of the bottom plate 2. A notch 11 is opened at the bottom end of the L-shaped plate 1. A round rod is rotatably connected between the opposite side surfaces inside the notch 11. A fixing block 22 through which the round rod penetrates and is fixed is fixedly connected to the top surface of the bottom plate 2. One end of the round rod penetrates the side surface of the L-shaped plate 1 and is fixedly connected with a worm gear 14. A chute one 15 is opened at the bottom end of one side surface of the L-shaped plate 1. A slider is slidably connected inside the chute one 15. One end of the slider is fixedly connected with a U-shaped frame 16. A worm 17 meshing with the worm gear 14 is fixedly connected between the opposite side surfaces inside the U-shaped frame 16. A spring 18 is fixedly connected between the slider and the chute one 15.

[0027] In this embodiment, by driving a plurality of spikes 21 into the slope surface, then rotating the L-shaped plate 1 to make the L-shaped plate 1 perpendicular to the horizontal plane, and making the bottom end of the equidistant mechanism 4 contact the slope surface. Then, move the worm 17 upward to disengage it from the worm gear 14, and rotate the L-shaped plate 1 to form an angle between the L-shaped plate 1 and the bottom plate 2. Then, move the equidistant mechanism 4 to the other end of the side surface of the L-shaped plate 1 and keep the length of the equidistant mechanism 4 unchanged at the initial position and the end position. Therefore, the L-shaped plate 1 can be made parallel to the slope surface. Then, release the worm 17. At this time, the worm 17 meshes with the worm gear 14 under the action of the spring 18, thereby preventing the L-shaped plate 1 from rotating again.

[0028] Embodiment 2

[0029] On the basis of the first embodiment, in order to make the L-shaped plate 1 parallel to the slope.

[0030] like Figure 6-7 As shown, in this embodiment, the equidistant mechanism 4 includes a rectangular sleeve 41 which is rotatable and slidingly located on the side of the L-shaped plate 1, and a movable plate 42 is slidably sleeved inside the rectangular sleeve 41, and a rotating seat 44 is rotatably connected to the bottom end of the movable plate 42, and a bolt 45 is screwed through the bottom end of one side of the rectangular sleeve 41, and a scale 46 is engraved on one side of the movable plate 42, and a slide groove 19 is provided on the other side of the L-shaped plate 1, and a connecting rod is rotatably connected to the top of one side of the rectangular sleeve 41, and one end of the connecting rod is fixedly connected to a cylindrical block 43 which slides with the slide groove 19, and the cross-section of the slide groove 19 is a convex structure.

[0031] In this embodiment, when the L-shaped plate 1 is perpendicular to the horizontal plane, the movable plate 42 can be loosened by rotating the bolt 45, and then the movable plate 42 is pulled down until the bottom surface of the rotating seat 44 is in contact with the slope surface, and then the scale 46 is observed to obtain the length of the movable plate 42 being pulled down. Due to the unevenness of the slope surface, the movable plate 42 can be first retracted into the rectangular sleeve 41, and the movable plate 42 can be fixed in the rectangular sleeve 41 with the bolt 45, and then the rectangular sleeve 41 can be moved along the slide groove 19 until the rectangular sleeve 41 moves to the other end of the slide groove 19, and then the movable plate 42 is pulled down by loosening the bolt 45 until the bottom surface of the rotating seat 44 contacts the slope surface, and then the position of the scale 46 is observed. If the position of the scale 46 is incorrect, the L-shaped plate 1 can be rotated at this time to adjust the angle between the L-shaped plate 1 and the bottom plate 2 until the position of the scale 46 is correct, and the L-shaped plate 1 is parallel to the slope surface.

[0032] Embodiment 3

[0033] On the basis of the first embodiment, in order to increase the stability of the rotating disk 3 during rotation.

[0034] like Figure 5 As shown, in this embodiment, annular grooves 33 are provided on the two opposite side surfaces of the turntable 3, and arc blocks 34 are fixedly connected to the two ends of the opposite side surfaces inside the rectangular hole 12. A plurality of connecting columns 35 are fixedly arranged at equal intervals on one side of the arc block 34, and a steel ball slidably engaged with the annular grooves 33 at the corresponding positions is fixedly connected to one end of the connecting column 35. The scale at the center line where the turntable 3 and the counterweight block 32 coincide and is close to the counterweight block 32 is the starting scale.

[0035] In this embodiment, the steel ball slides in the annular groove 33 at the corresponding position, and then is limited by the arc block 34 and the connecting column 35 at the corresponding position, so that the turntable 3 can be prevented from shaking during rotation.
