Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figure 1-7, the present invention provides a technical solution: a surveying ruler for Danxia landform, which includes a mounting plate 1. Hinged legs 2 are hinged at the four corners of the lower surface of the mounting plate 1. The lower ends of the hinged legs 2 are hinged with hinged feet 3. A mounting frame 4 is fixedly connected to the upper surface of the mounting plate 1. A rotating rod 5 is rotatably connected to the side wall of the mounting frame 4 through a bearing. One end of the rotating rod 5 penetrates to the left side of the mounting frame 4. A protractor mechanism 6 is arranged at the left end of the rotating rod 5. A laser rangefinder 7 is fixedly connected to the middle part of the outer wall of the protractor mechanism 6. A placement groove 8 is opened on the right side of the mounting plate 1. A clamping plate 9 is placed inside the placement groove 8. Four threaded holes are opened on the clamping plate 9. Threaded legs 10 are threadedly connected inside the threaded holes. A hinge seat 11 is hinged in the middle of the upper side of the clamping plate 9. A target 12 is fixedly connected to the upper side of the hinge seat 11. A display 15 is fixedly connected to the rear side of the upper surface of the mounting plate 1. A balance mechanism 13 is also arranged on the upper side of the clamping plate 9. A protection mechanism 14 is arranged on the front side of the mounting plate 1;

[0031] When in use, if it is necessary to measure a short distance, only the laser rangefinder 7 can be used for measurement. If it is necessary to measure a long distance, the device is carried to a measurement point. Then the clamping plate 9 is taken out, and the threaded legs 10 are rotated to make the clamping plate 9 at an appropriate height. Then the target 12 is oriented towards another measurement point. Then the mounting plate 1 is moved to the second measurement point, and the laser rangefinder 7 is oriented towards the target 12, and the distance measurement can be completed. When placing the mounting plate 1, the hinged legs 2 and the hinged feet 3 can provide stable support for the mounting plate 1;

[0032] The protractor mechanism 6 includes an extension rod 601. One end of the extension rod 601 is fixedly connected to one end of the rotating rod 5. A pointer 602 is fixedly connected to the outer wall of the other end of the extension rod 601. A support is arranged on the left side of the mounting plate 1. A scale 603 is rotatably connected to the right side of the support through a bearing. A first counterweight 604 is fixedly connected to the lower side of the scale 603. The mass of the first counterweight 604 is greater than the mass of the scale 603, and the scale 603 is located on the left side of the pointer 602. The length of the pointer 602 is less than the diameter of the scale 603;

[0033] When the laser rangefinder 7 is oriented towards the target 12, since the Danxia landform has large height fluctuations, the laser rangefinder 7 may drive the rotating rod 5 to deflect. When the rotating rod 5 deflects, it will drive the pointer 602 to deflect, so that the pointer 602 deflects relative to the scale 603. Since the scale 603 is weighted by the first counterweight 604 and always keeps an angle with the ground unchanged, an angle difference is generated between the two. The height difference between the two points can be calculated through the relative distance between the two points and the deflection angle of the laser rangefinder 7, and then displayed through the display 15. The specific calculation method is:

[0034] h = c * sin(X)

[0035] Where: h is the height difference between two points, c is the length of the hypotenuse, and X is the slope angle;

[0036] The protection mechanism 14 includes a battery slot 401 which is a groove opened on the lower side of the mounting plate 1. A gas generator 402 is also fixedly connected to the lower side of the mounting plate 1. A motion detector 403 is arranged on one side of the gas generator 402. A connecting pipe 404 is fixedly connected to the front side of the gas generator 402. An installation opening penetrating up and down is opened on the front side of the mounting plate 1. An installation box 405 is fixedly connected to the inside of the installation opening. The upper side of the installation box 405 is open. An airbag 406 is fixedly connected to the lower side of the inner wall of the installation box 405. One end of the connecting pipe 404 penetrates the installation box 405 and is fixedly connected to the outer wall of the airbag 406. The inside of the airbag 406 is communicated with the output side of the gas generator 402. A first groove is opened on the left side wall of the placement slot 8. A first spring 407 is fixedly connected to the left side of the inner wall of the first groove. A first slider 409 is fixedly connected to the right side of the first spring 407. A first conductive block 408 is fixedly connected to the middle of the first slider 409. Both the upper and lower ends of the first conductive block 408 are in contact with the inner wall of the first groove. Second conductive blocks 410 are fixedly connected to both the right side of the upper surface and the right side of the lower surface of the first groove. The right side of the first slider 409 is of an inclined structure, and the height of the upper surface of the right end of the first slider 409 is less than the height of the upper surface of the left end of the first slider 409. The first conductive block 408 is located on the left side of the second conductive blocks 410, and the upper second conductive block 410 is electrically connected to the power supply, and the lower second conductive block 410 is electrically connected to the motion detector 403, and the two second conductive blocks 410 are located on the moving path of the first conductive block 408, and in this state, the first spring 407 is in a compressed state;

[0037] After the clamping plate 9 is taken out of the placement slot 8, the first slider 409 moves to the right due to the elasticity of the first spring 407, so that the first conductive block 408 connects the two second conductive blocks 410, and then the motion detector 403 starts to work to detect the stability of the mounting plate 1. When it detects that the mounting plate 1 is overturned or the like, the gas generator 402 is started, so that the gas generator 402 quickly conveys gas into the inside of the airbag 406 through the connecting pipe 404, and then the airbag 406 expands to block the front side of the laser rangefinder 7, so that the device can be protected by the airbag 406 when it is overturned, avoiding scratching the front side of the laser rangefinder 7, and thus ensuring the use safety on the ground where it is easy to loosen;

[0038] When the clamping plate 9 is put back into the placement slot 8, the first slider 409 will be retracted back into the first groove again, so that the first conductive block 408 moves out from between the two second conductive blocks 410, and then the motion detector 403 stops working, thus avoiding accidental touch during transportation and storage;

[0039] The balance mechanism 13 includes a motor 305. An installation hole is formed in the clamping plate 9, and the inner wall of the installation hole in the clamping plate 9 is fixedly connected to the outer wall of the motor 305. A second counterweight 306 is fixedly connected to the output end of the motor 305. A second groove is formed on the left side of the clamping plate 9. A second spring 301 is fixedly connected to the right side of the inner wall of the second groove. The left end of the second spring 301 is fixedly connected to a second slider 302. A third conductive block 303 is fixedly connected to the middle of the second slider 302. Both the upper and lower ends of the third conductive block 303 are in contact with the inner wall of the second groove. Fourth conductive blocks 304 are arranged on both the upper side and the lower part of the second groove. Both of the two fourth conductive blocks 304 are located on the moving path of the third conductive block 303. The motor 305 is electrically connected to the lower fourth conductive block 304, and the upper fourth conductive block 304 is electrically connected to the power supply. The third conductive block 303 is located on the right side of the second slider 302, and in this state, the second spring 301 is in a compressed state. The second counterweight 306 is of a semi-circular structure. A socket is formed on one side of the second counterweight 306. A plug rod 307 is inserted into the inner wall of the socket. One end of the plug rod 307 is fixedly connected to a third spring 309. The outer wall of the third spring 309 is fixedly connected to the inner wall of the second counterweight 306. The other end of the plug rod 307 is fixedly connected to a third counterweight 308, and the mass of the third counterweight 308 is less than the mass of the second counterweight 306;

[0040] When the clamping plate 9 is placed at the first point position, since the clamping plate 9 is separated from the inside of the placement groove 8, at this time, the second spring 301 pushes the second slider 302 outwards, thereby enabling the third conductive block 303 to connect the fourth conductive block 304, causing the motor 305 to drive the second counterweight 306 to rotate. During its stable rotation, due to the conservation of angular momentum, the target 12 is not easily overturned by the wind;

[0041] And at the initial stage of its rotation, since the mass of the second counterweight 306 is greater than the mass of the third counterweight 308, after this device is placed on the ground, when the motor 305 drives the second counterweight 306 to rotate, its center of gravity changes during the rotation, thereby causing the clamping plate 9 and the threaded legs 10 to vibrate, making the lower surface of the threaded legs 10 contact the ground more evenly, and the gravel on the ground can be paved more evenly through vibration. Subsequently, due to the centrifugal force, the third counterweight 308 drives the plug rod 307 to pull out of the inside of the second counterweight 306, and at the same time, the third spring 309 undergoes elastic deformation. Subsequently, the mass on one side of the third counterweight 308 increases, and finally the masses on both sides of the motor 305 are equal, and then it can rotate evenly to support the target 12 and prevent it from being overturned and damaged.
