DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] When in use, if it is necessary to measure a short distance, the laser rangefinder 7 can be used for measurement. If it is necessary to measure a long distance, the device is moved to a measuring point, and then the cardboard 9 is taken out, and the threaded legs 10 are rotated to make the cardboard 9 at a suitable height, and then the target 12 is directed to another measuring point, and then the mounting plate 1 is moved to the second measuring point, and the laser rangefinder 7 is directed to the target 12, and the distance measurement can be completed. When the mounting plate 1 is placed, the mounting plate 1 can be provided with stable support through the articulated legs 2 and the articulated feet 3;

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

[0033] When the laser rangefinder 7 is directed toward the target 12, due to the large fluctuations in the height of the Danxia landform, the laser rangefinder 7 may drive the rotating rod 5 to deflect, and when the rotating rod 5 deflects, the pointer 602 will be driven to deflect, so that the pointer 602 deflects relative to the scale 603. Since the scale 603 is counterweighted by the first counterweight block 604 and always maintains an angle unchanged with the ground, an angle difference is generated between the two points. The height difference between the two points can be calculated by the relative distance between the two points and the deflection angle of the laser rangefinder 7, and then displayed on the display 15. The specific calculation method is:

[0034] h=c*sin(X)

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

[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. A mounting opening that runs through the upper and lower sides is opened on the front side of the mounting plate 1. A mounting box 405 is fixedly connected to the inside of the mounting opening. The upper side of the mounting box 405 is opened. An airbag 406 is fixedly connected to the lower side of the inner wall of the mounting box 405. One end of the connecting pipe 404 passes through the mounting box 405 and is fixedly connected to the outer wall of the airbag 406. The interior of the airbag 406 is connected to the output side of the gas generator 402. A first groove is opened on the left side wall of the placement slot 8.

[0037] After the card 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, so that the motion detector 403 works to detect the stability of the mounting plate 1. When the mounting plate 1 is detected to have overturned, the gas generator 402 is started to quickly supply gas to the inside of the airbag 406 through the connecting pipe 404, so that the airbag 406 is expanded to block the front side of the laser rangefinder 7, so that the device can be protected by the airbag 406 when it overturns, so as to avoid scratching the front side of the laser rangefinder 7, thereby ensuring the safety of use on loose ground;

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

[0039] The balancing mechanism 13 includes a motor 305, a mounting hole is provided on the card plate 9, the inner wall of the mounting hole on the card plate 9 is fixedly connected to the outer wall of the motor 305, the output end of the motor 305 is fixedly connected to a second counterweight block 306, a second groove is provided on the left side of the card plate 9, a second spring 301 is fixedly connected to the right side of the inner wall of the second groove, a second slider 302 is fixedly connected to the left end of the second spring 301, a third conductive block 303 is fixedly connected to the middle of the second slider 302, the upper and lower ends of the third conductive block 303 are both in contact with the inner wall of the second groove, fourth conductive blocks 304 are provided on the upper side and the lower part of the second groove, and the two fourth conductive blocks 304 are both located on the third conductive block 3 03, the motor 305 is electrically connected to the fourth conductive block 304 on the lower side, the fourth conductive block 304 on the upper side 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 block 306 is a semicircular structure, a socket is provided on one side of the second counterweight block 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 the third spring 309, the outer wall of the third spring 309 is fixedly connected to the inner wall of the second counterweight block 306, the other end of the plug rod 307 is fixedly connected to the motor 305, and the mass of the third counterweight block 308 is less than the mass of the second counterweight block 306;

[0040] When the card plate 9 is placed at the first position, since the card plate 9 is separated from the inside of the placement slot 8, the second spring 301 pushes the second slider 302 outward, so that the third conductive block 303 connects the fourth conductive block 304, so that the motor 305 drives the second counterweight block 306 to rotate. During the stable rotation process, due to the conservation of angular momentum, the target 12 is not easily blown over by the wind.

[0041] And in 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 the 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 process, thereby causing the clamping plate 9 and the threaded leg 10 to vibrate, so that the lower surface of the threaded leg 10 contacts the ground more evenly, and the gravel on the ground can be paved more evenly through vibration. Subsequently, due to centrifugal force, the third counterweight 308 will drive the insertion rod 307 to be pulled out of the interior of the second counterweight 306, and at the same time, the third spring 309 will be elastically deformed, and then the mass of one side of the third counterweight 308 will be increased, and finally the mass on both sides of the motor 305 will be equal, and then it can rotate evenly to support the target 12 to prevent overturning and damage.
