A lens 16 is transversely arranged on the drawing box body 1 in a penetrating manner, and the light beam emitter 2 and the light ray induction plate 3 are both arranged inside the drawing box body 1; because when drawing the function image of mountain body, use beam emitter 2 as the drawing device, so require the installation setting between beam emitter 2 and the light tablet 3 to go on under the environment of no light, and then set up beam emitter 2 and light tablet 3 in the inside of drawing box 1 for when the drawing of carrying out the mountain body function image, the light that can not have the external environment under disturbs, and guarantee device can be normal draws measured mountain body function image. The drawing box body 1 is transversely provided with a lens 16 in a penetrating mode, the purpose is to enable a drawer to well observe the contour shape of the mountain, the lens 16 arranged at the position is a telescope with adjustable focal length, so that the drawer can clearly see the contour structure of the mountain to be drawn when drawing, and the obtained mountain function image is more accurate. Light beam emitter 2 and light tablet 3 all set up in the inside of drawing box 1, 2 lower extremes of light beam emitter are equipped with universal rotary device, draw box 1 and can use universal rotary device to be the universal rotation of centre of a circle, after setting up universal rotary device, the person of drawing is when this device of operation, only need fix the universal rotary device under the light beam emitter 2, universal rotary device no longer changes for the position on ground promptly, make the person of drawing remove and draw box 1, describe the concrete shape of massif through lens 16, and then obtain the function image of massif. The universal rotating device arranged here is a universal ball 4, and a cambered surface ball groove 5 which is used for arranging the universal ball 4 and enabling the universal ball 4 to rotate universally in the bottom surface of the drawing box body 1 is arranged on the bottom surface of the drawing box body, so that the drawing box body 1 and the universal ball 4 can rotate universally relatively. In a normal situation, when a function image of a mountain is drawn, in order to conveniently draw the whole image of the mountain, the selected measurement position should be under the feet of the mountain, so that the device can draw the whole function image of the mountain, but when drawing is performed, if manual operation is used, the precision of the drawn function image cannot be guaranteed, so that a device capable of automatic adjustment needs to be arranged on the basis of the device. The west lower end of the servo motor 6 is connected with a supporting connecting rod, and the height of the supporting connecting rod can be adjusted conveniently, so that the triangular supporting frame 15 is arranged at the lower end of the supporting connecting rod, and the device is convenient to mount and fix.
Automatic horizontal rotary device:
when the mountain function image is drawn, the transverse distance of the mountain cannot be changed, namely, the variable x in the function image is a fixed value, so that when the function image is drawn, a drawer does not need to manually operate on the change of the transverse distance of the mountain, namely, the feeding amount of x in unit time is set, the drawer only needs to control the change of the height of the mountain, the operation burden of workers is relieved, the workers can control the change of the up-and-down movement of the drawing box body 1 in a centralized manner, and the function image drawn by the drawer is more accurate; the automatic transverse rotating device selected by the device is a servo motor 6, the servo motor 6 is connected with the drawing box body 1, because the device is convenient to operate and more convenient to rotate, the servo motor 6 is arranged on the same axis of the universal ball 4 and is connected with the drawing box body 1 below the universal ball 4 to drive the drawing box body 1 to rotate, in order to ensure that the universal ball 4 can not move along with the rotation of the drawing box body 1 when the servo motor 6 drives the drawing box body 1 to rotate, the lower end of the universal ball 4 is required to be connected to the ground, and a connecting and fixing rod frame is independently arranged to be inconvenient to carry, so that the bottom surface of the universal ball 4 is connected with a C-shaped connecting rod 10, the other end of the C-shaped connecting rod 10 is connected to a supporting rod frame 9 on the bottom surface of the servo motor 6, so that the servo motor 6 can drive the drawing box body 1 to rotate, the universal ball 4 can not follow the drawing box 1 and rotate, and the C-shaped connecting rod 10 can not prevent the servo motor 6 from driving the drawing box 1 to rotate, so that the rotation angle of the drawing box 1 is larger. The servo motor 6 can control the rotation angle of the servo motor 6 by electric signal pulses, so that the rotation angle can be controlled, but the servo motor 6 is directly used as a power source for drawing the transverse rotation of the box body 1, the requirement on the driving angle of the servo motor 6 is very fine, a speed reducer 7 needs to be connected to an output shaft of the servo motor 6, the rotation speed output by the speed reducer 7 is the actual rotation angle of the drawing box body 1 in unit time, the requirement on the rotation precision of the servo motor 6 on a certain angle is very high, the number of the accurate rotation turns of the servo motor 6 is very easy to control the servo motor 6, the output shaft of the speed reducer 7 is connected to the bottom surface of the drawing box body 1 through a connecting rod 8, and the drawing box body 1 is driven to rotate transversely. Therefore, the speed reducer 7 not only plays a role in transmitting the rotation angle, but also can enable the rotation angle of the drawing box body 1 to be more accurate, the rotation angle value of the drawing box body 1 in unit time is a certain value, and the rotation angle in unit time can be adjusted by adjusting the rotation number of the servo motor 6 according to the transverse distance of different mountains, so that drawing detection of different mountains is realized.
Because the specific number of rotations of servo motor 6 in unit time needs to be set according to the angle of drawing box 1 lateral rotation, and the angle of drawing box 1 lateral rotation, that is, the rotation angle from the beginning to the end of the mountain, needs to be measured and known. Therefore, an angle measuring device is required to be arranged on the automatic transverse rotating device, the angle measuring device comprises an angle dial 13 and an angle marking disc 14, and the angle dial 13 and the angle marking disc 14 can rotate relatively. When the lateral rotation angle of the mountain is measured, an angle dial 13 arranged outside an output shaft of the speed reducer 7 is fixed, an angle marking disc 14 arranged at the upper end of the output shaft is rotated, when the rotation is started, the center of a lens 16 is aligned to the initial section of the mountain, the position of the rotation measurement is the end of the mountain, the angle of the angle marking disc 14 rotating relative to the angle dial 13 is the angle change of the mountain function image on the lateral distance, and a worker selects the rotation number of the servo motor 6 in unit time according to the angle value to draw the automatic rotation of the box body 1 in the lateral direction.
Vertical direction adjusting device:
when drawing a function image of a mountain, because the angle of the mountain in the transverse rotation is a fixed value, after the angle measurement device measures the angle, the servo motor 6 is given a specified rotation angle, so that the rotation of the transverse angle in unit time is realized, but the value measured in the vertical direction is the height of the mountain in different transverse distances, so that the value is an uncertain variable value, so that a drawer needs to manually measure, but the measurement precision cannot be guaranteed by measuring in the traditional measurement mode, therefore, a vertical direction adjusting device needs to be arranged, the vertical direction adjusting device comprises a coarse screw adjusting mechanism 11 and a fine screw adjusting mechanism 12, the coarse screw adjusting mechanism 11 and the fine screw adjusting mechanism 12 are both arranged on the upper end of the output shaft of the speed reducer 7 and the connecting rod 8 of the drawing box body 1, the connecting rod 8 arranged here is selected from the connecting rod 8 with the length being telescopic, so that the coarse screw adjusting mechanism 11 and the fine screw adjusting mechanism 12 can drive the connecting rod 8 to extend or shorten, and therefore the connecting rod 8 and the connecting end of the drawing box body 1 are hinged. The coarse screw adjusting mechanism 11 and the fine screw adjusting mechanism 12 provided here refer to a coarse focusing screw mechanism and a fine focusing screw mechanism of a conventional optical microscope, and the purpose of the coarse focusing screw mechanism and the fine focusing screw mechanism is to realize the refinement of the feeding amount in the vertical direction when the adjustment in the vertical direction of the box body 1 is performed. Because the automatic transverse rotation device who sets up can ensure transverse rotation's unit rotation amount, and in order to ensure the accuracy of drawing the image, its unit rotation amount can be very little, so coarse screw adjustment mechanism 11 and fine screw adjustment mechanism 12's setting can ensure that the person of drawing has sufficient time to make and draws box 1 and adjust on vertical direction, also can ensure the accurate degree of the mountain function image of drawing moreover.
The using method comprises the following steps:
the proper position of the device is found, the position with flat ground and wide visual field under the mountain foot is preferably selected during selection, and measurement is carried out after the proper position is found.
Firstly, the whole device is fixed to a proper position by using a triangular support frame 15, the triangular support frame 15 is adjusted, and the device is arranged to a horizontal position as much as possible. The drafter observes the shape of the mountain through the lens 16, determines the starting end of the mountain, and adjusts the coarse screw adjusting mechanism 11 and the fine screw adjusting mechanism to adjust the central position of the lens 16 to the vertical height of the starting end; and adjusting the servo motor 6 to enable the center of the lens 16 to fall to the initial end, recording the relative positions of the angle dial 13 and the angle marking disc 14 at the moment, starting the servo motor 6, bringing the drawing box body 1 to the transverse position of the final end, further obtaining the change of the angle between the angle dial 13 and the angle marking disc 14, and inputting the number of rotation turns of the servo motor 6 in unit time by drawing personnel according to the measured angle value to further perform measurement operation.
The operation starts, the servo motor 6 is started, the plotter observes the shape of the mountain at the moment, the fine screw mechanism is adjusted, and the adjustment is carried out according to the change of the height of the mountain, because the set number of servo turns is small along with the driving ratio between the speed reducers 7 in order to guarantee the accuracy of the image drawing, so the plotter concentrates the attention during the measurement, and the device can be operated by a plurality of plotters in turn until a complete mountain function image is obtained.
Therefore, the device for predicting the landslide based on the mathematical function image drawing method can draw the shape graph of the mathematical function of the mountain conveniently, so that a worker can analyze the change of the tangent slope of a certain section of the function image of the mountain according to the drawn function image to judge whether the mountain has the danger of landslide, and further can carry out specific exploration and investigation on the mountain surface with the landslide danger in time.
