Description

Technical Field

[0001] The present invention relates to the technical field of geological investigation and mapping, and in particular to a method and device for geological investigation and mapping. Background Art

[0002] When conducting geological surveys and mapping, various geological mapping instruments are needed, one of the most basic and common instruments is the geological compass. The functions of the geological compass include measuring the occurrence of rock formations and measuring the location of the target.

[0003] The occurrence of rock formations includes the direction, inclination and dip of the rock formations. The dip of the rock formations needs to be measured using the vertical level on the geological compass. After one of the long sides of the geological compass is attached to the rock surface and perpendicular to the direction of the rock formation, the bubble in the vertical level will automatically shift according to the angle difference between the dip of the rock formation and the current angle of the vertical level. At this time, by moving the vertical level to make it move counterclockwise or clockwise around the center of the geological compass, the bubble will move to the middle line, and then read the vertical scale to measure the dip of the rock formation.

[0004] This method of manually adjusting the orientation of the vertical level to center the bubble is not only inefficient and inaccurate, but also when measuring some rock formations, if the location of the rock formation makes it difficult to observe one side of the geological compass dial through the human eye or the compass reflector, it is impossible to manually observe the bubble position of the vertical level and adjust it.

[0005] Therefore, in order to solve the above technical problems existing in the prior art, a method and device for geological investigation and mapping are proposed. Summary of the invention

[0006] The present invention provides a method and device for geological investigation and mapping, which can automatically trigger a vertical level to rotate counterclockwise or clockwise along the center of a compass to center when measuring the inclination of a rock layer, thereby eliminating the need for manual adjustment of the vertical level and greatly improving the beneficial effect of measurement accuracy. The invention solves the problem in the prior art mentioned in the above background technology that when measuring some rock layers, if the position of the rock layer makes it inconvenient for one side of the dial of the geological compass to be observed by the human eye or the reflector of the compass, it is impossible to manually observe the bubble position of the vertical level and adjust it.

[0030] The present invention has the following beneficial effects:

[0031] 1. The method and device for geological survey and mapping: When conducting geological survey and mapping, when using a geological compass to measure the occurrence of rock formations or the position of a target, the prior art requires human eyes to observe and adjust the long level so that the bubble in the long level is centered and the scale is read. This measurement method is relatively troublesome and has low adjustment accuracy.

[0032] In this device, a slide is used to replace the air bubble in the glass tube. According to the automatic forward and backward deviation of the slide when measuring the rock formation inclination, one of the first drive assembly or the second drive assembly can be triggered, and the motor installed in the compass housing is driven to drive the turntable to rotate clockwise or counterclockwise, so that the glass tube rotates automatically with the turntable to gradually center the slide. When the slide reaches the middle position of the glass tube, the motor is automatically disconnected. This facilitates the measurement of rock formation inclination and greatly improves the measurement accuracy.

[0033] 2. The method and device for geological survey and mapping, the slide can trigger the circuit connection of the first drive component or the second drive component according to the forward and backward movement. In the circuits of the first drive component and the second drive component, the positive and negative poles of the power supply are opposite, so when the two circuits are connected, the motor can be driven to output clockwise or counterclockwise. In addition, the slide triggers the circuit connection of the first drive component or the second drive component through a set of sliding rheostats. When the offset distance of the slide is not large, the required rotation angle is not large to be centered. At this time, the current passed into the motor is also automatically reduced through the control of the sliding rheostat, which can reduce the rotation speed of the turntable and the glass tube.

[0034] 3. The method and device for geological investigation and mapping can adjust the range of the slide when it reaches the center position through manual control to adjust the measurement accuracy of the rock layer inclination. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0049] 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.

[0050] For example, see Figure 1-Figure 9 , a method and device for geological survey and mapping, comprising the following steps:

[0051] S1. When mapping the occurrence of rock formations, the direction of the rock formations is measured by the direction measuring mechanism 200 installed on the compass housing 100;

[0052] S2, placing one of the side lines 110 of the compass housing 100 on the rock layer, and making the side line 110 perpendicular to the strike line measured in step S1, and then measuring the rock layer inclination by the inclination measuring mechanism 300 installed on the compass housing 100;

[0053] The S1 step specifically includes:

[0054] Place one of the side lines 110 of the compass housing 100 on the rock layer, and then adjust the position of the compass housing 100 up and down and left and right so that the bubble in the circular level 210 in the direction measurement mechanism 200 is centered, and then read the reading on the horizontal scale plate 230 where the south needle or north needle of the compass 220 is pointing, which is the direction of the rock layer;

[0055] The S2 step specifically includes:

[0056] S21, when the slide 322 in the long level 320 is at the front side of the glass tube 321, the first driving assembly 360 is automatically triggered, and the first driving assembly 360 drives the rotating assembly 350 to operate, so that the turntable 310 drives the long level 320 to rotate counterclockwise. During the counterclockwise rotation of the long level 320, the slide 322 gradually moves backward into the glass tube 321 until the slide 322 moves to the middle side of the glass tube 321, and the rotating assembly 350 automatically stops operating;

[0057] S22, when the slide 322 in the long level 320 is at the inner rear side of the glass tube 321, the second driving assembly 370 is automatically triggered, and the second driving assembly 370 drives the rotating assembly 350 to operate, so that the turntable 310 drives the long level 320 to rotate clockwise, so that when the slide 322 gradually moves forward to the middle side of the glass tube 321, the rotating assembly 350 automatically stops operating;

[0058] S23, after the rotating disk 310 stops rotating, the directional arrow 330 on the rotating disk 310 is read, and the reading on the vertical scale plate 340 at this time is read, which is the inclination angle of the rock formation;

[0059] A glass cover 120 is disposed on the compass housing 100. The direction measuring mechanism 200 further includes a connecting arm 240 and a rotating rod 250. The connecting arm 240 is disposed on the inner wall of the compass housing 100. The circular level 210 is mounted on the connecting arm 240. The rotating rod 250 is rotatably disposed on the glass cover 120. The compass 220 is mounted on the rotating rod 250.

[0060] A compass cover 140 is provided on the compass housing 100 via a hinge 130 , a reflector 150 is provided on the compass cover 140 , a center line 160 and a through hole 170 are provided on the reflector 150 , a rotating shaft 180 is rotatably provided on the compass housing 100 , and an aiming anvil 190 is provided on the rotating shaft 180 .

[0061] In this embodiment, the compass housing 100 and the strike measurement mechanism 200 and the inclination measurement mechanism 300 installed thereon constitute the main body of the geological compass, which can be used to measure the occurrence of rock formations or the location of a target.

[0062] When measuring the direction of rock formations, the long side of the compass housing 100, i.e., the edge line 110, is placed close to the rock surface, and the circular level 210 is observed through the transparent glass cover 120 on the compass housing 100. The circular level 210 is filled with liquid, and there is a bubble in the liquid. The position of the bubble is observed and the compass housing 100 is moved. During the movement, the edge line 110 is kept close to the rock surface until the bubble is centered. At this time, the horizontal scale plate 230 opened on the inner wall of the compass housing 100 rotates with the compass housing 100, and the scale of the horizontal scale plate 230 pointed to by the south pole or north pole of the compass 220 is the direction of the rock formation.

[0063] By attaching the left line or the right line of the compass housing 100 to the rock layer, the inclination of the rock layer can be measured using the same measurement method as above.

[0064] When measuring the inclination of rock formations, the prior art requires that the compass housing 100 be placed on its side, that is, its front end face or rear end face be attached to the rock layer surface, and the edge line 110 be perpendicular to the above-measured rock formation strike line, and then the elongated level 320 be rotated around the center of the compass housing 100 until the bubble is centered to read the reading of the vertical scale 340.

[0065] The improvement of the present invention is that the glass tube 321 is installed on the turntable 310, and the turntable 310 can rotate around the central axis of the compass housing 100. A motor 351 is installed on the bottom wall of the compass housing 100, and the output shaft of the motor 351 is coaxially connected to the turntable 310.

[0066] A slide 322 is used in the glass tube 321 to replace bubbles. The movement law of the lighter slide 322 is the same as that of bubbles in the liquid. The slide 322 is in a ring shape. The liquid in the glass tube 321 can flow on both sides through the hole in the slide 322, reducing the resistance encountered by the slide 322 when sliding along the inner wall of the glass tube 321.

[0067] After the compass housing 100 is turned sideways, if the slide 322 is in Figure 2 The slide 322 automatically triggers the first drive assembly 360, and the first drive assembly 360 drives the rotating assembly 350. The output shaft of the rotating assembly 350 drives the turntable 310 to rotate counterclockwise, and the long level 320 rotates counterclockwise around the central axis of the compass housing 100, so that the slide 322 moves backward relative to the glass tube 321, until the slide 322 moves to the middle position of the glass tube 321, the rotating assembly 350 stops running, and the turntable 310 is stationary. At this time, the directional arrow 330 opened on the turntable 310 points to the scale on the vertical scale plate 340 opened on the inner wall of the compass housing 100, which is the rock formation inclination. Automatic measurement is achieved.

[0068] The compass cover 140, reflector 150, center line 160, through hole 170, aiming anvil 190 and other structures installed on the compass housing 100 are used for other measurement functions of the geological compass, which are conventional technical means and are not described in detail here.

[0073] The positive electrode of the second battery compartment 371 is electrically connected to the fourth connector 376 via the fourth wire 377, the third connector 375 is electrically connected to the second collector ring 353 via the fifth wire 378, and the first collector ring 352 is electrically connected to the negative electrode of the second battery compartment 371 via the sixth wire 379;

[0074] The inclination angle measuring mechanism 300 further includes an electrical connection assembly 380, which includes a third insulating seat 381 disposed between the first insulating seat 362 and the second insulating seat 372, and a slider 382 is slidably disposed on the first insulating seat 362, the third insulating seat 381 and the second insulating seat 372, and the slider 382 is connected to the slide 322;

[0075] The slider 382 is provided with a power connection piece 383. When the slider 382 slides onto the first insulating seat 362, the first metal rod 363 is electrically connected to the first terminal 364 through the power connection piece 383.

[0076] When the slider 382 slides onto the second insulating seat 372 , the second metal rod 373 is electrically connected to the second terminal 374 through the electrical connection sheet 383 ;

[0077] The elongated level 320 further includes a first slide groove 323 formed on the glass tube 321 , a connecting rod 324 is disposed on the slide plate 322 , the slider 382 is connected to the connecting rod 324 , and the connecting rod 324 is slidably connected in the first slide groove 323 ;

[0078] The inner walls of both sides of the first slide groove 323 are provided with sealing grooves 325, and the connecting rod 324 is provided with a sealing plate 326, which is slidably connected to the first slide groove 323 and the two sealing grooves 325;

[0079] Connecting seats 327 are provided on the turntable 310 and the glass tube 321. The elongated level 320 also includes a damper 328 and a spring 329. The two ends of the damper 328 are respectively hinged to the two connecting seats 327 through hinge shafts, and the two ends of the spring 329 are respectively connected to the two ends of the damper 328.

[0080] In this embodiment: the motor 351 is located at the center of the compass housing 100, and the first collector ring 352 and the second collector ring 353 installed on the motor 351 are respectively connected to the positive and negative pole interfaces of the motor 351. The function of the first collector ring 352 and the second collector ring 353 is to maintain the electrical connection between the wire and the positive and negative poles of the motor 351 when the wire rotates with the turntable 310.

[0081] The first battery compartment 361 and the second battery compartment 371 are installed on the left side of the motor 351. The first battery compartment 361 and the second battery compartment 371 can use cylindrical batteries as shown in the figure, or other power supply methods. The positive and negative poles of the first battery compartment 361 and the second battery compartment 371 are in opposite directions.

[0082] On the left side of the first battery compartment 361 and the second battery compartment 371 and located at the lower side of the glass tube 321 are the first driving assembly 360 and the second driving assembly 370 distributed along the front-to-back direction, and the two are symmetrical front-to-back.

[0083] In the glass tube 321, the resistance of the sliding piece 322 sliding along the inner wall of the glass tube 321 can be reduced by reducing the friction coefficient and other settings. The sliding piece 322 will drive the connecting rod 324, the sealing plate 326 and the slider 382 to move forward and backward together. During the movement of the sliding piece 322 forward and backward, since the sealing plate 326 slides along the two sealing grooves 325 that are longer in the front and rear, the sealing plate 326 will not be separated from any of the sealing grooves 325, so that the sealing plate 326 can always seal the first sliding groove 323 and the two sealing grooves 325. Thus, the sealing performance of the glass tube 321 is maintained.

[0084] When the slide 322 is naturally in the middle of the glass tube 321 under the action of gravity, the slider 382 and the power strip 383 are now on the third insulating seat 381, and the power strip 383 is not in contact with the first metal rod 363, the first terminal 364, the second metal rod 373, and the second terminal 374. At this time, the circuits of the first drive assembly 360 and the second drive assembly 370 are both disconnected. The motor 351 is not powered.

[0085] When the slide 322 is located in front of the glass tube 321 under the action of gravity, the electrical connection piece 383 slides onto the first insulating seat 362 , and the conductive electrical connection piece 383 connects the first metal rod 363 and the first terminal 364 .

[0086] At this time, the current flows from the positive electrode of the first battery compartment 361 through the first wire 367 to the second connector 366, and then passes through the first terminal 364, the power plate 383, the first metal rod 363 to the first connector 365 in sequence, and then from the first connector 365 through the second wire 368 to the first collector ring 352, and is connected to the positive electrode of the motor 351. The negative electrode of the motor 351 is connected to the negative electrode of the first battery compartment 361 through the second collector ring 353 and the third wire 369, forming a circuit of the first driving component 360. The motor 351 is energized at this time, driving the turntable 310 to rotate counterclockwise.

[0087] When the glass tube 321 rotates counterclockwise with the turntable 310, the sliding piece 322 and the power connection piece 383 gradually move backwards until the power connection piece 383 slides to the position of the third insulating seat 381, and the circuit of the first driving component 360 is disconnected, and the motor 351 stops running.

[0088] The insulated first insulating seat 362, the first metal rod 363, and the first terminal 364 can form a sliding rheostat. When the sliding piece 322 is not tilted forward relative to the glass tube 321, the angle of rotation of the turntable 310 is small. Correspondingly, the power connection piece 383 is located at the rear position on the first metal rod 363 and the first terminal 364. At this time, the length of the power connection on the first terminal 364 is large, and the resistance is large. Therefore, the current of the motor 351 is small, and the speed of counterclockwise rotation is slow.

[0089] Similarly, when the slide 322 is at the rear side of the glass tube 321 under the action of gravity, the electrical connection piece 383 slides onto the second insulating seat 372 , and the conductive electrical connection piece 383 connects the second metal rod 373 and the second terminal 374 .

[0090] At this time, the current flows from the positive pole of the second battery compartment 371 through the fourth wire 377 to the fourth connector 376, and then sequentially through the second terminal 374, the power plate 383, the second metal rod 373 to the third connector 375, and then from the third connector 375 through the fifth wire 378 to the second collector ring 353, and is connected to the negative pole of the motor 351. The positive pole of the motor 351 is connected to the negative pole of the second battery compartment 371 through the second collector ring 353 and the sixth wire 379, forming a circuit of the second drive assembly 370, and the motor 351 is powered on at this time. However, it is equivalent to swapping the positive and negative poles of the power supply, so it will drive the turntable 310 to rotate clockwise.

[0091] During the rotation of the turntable 310, in order to ensure that the slide 322 in the glass tube 321 is not affected and can slide back to the middle side of the glass tube 321 in a relatively stable manner, a spring damper is formed by installing a connecting seat 327, a damper 328 and a spring 329 on both sides of the glass tube 321 to provide a shock absorbing effect.

[0092] It should be supplemented that a circuit switch can be added to the circuit of the first driving component 360 or the circuit of the second driving component 370, and when the function of automatically rotating the elongated level 320 to center the slide 322 is used, the switches of the two circuits can be turned on. Before using this function, the two circuits can be closed.

[0093] The slide 322 and the electrical connection assembly 380 can be made light in weight and have low friction resistance, so that the slide 322 has the same effect as the bubble in the level.

[0094] Embodiment 3: This embodiment is an improvement made on the basis of Embodiment 2. For details, please refer to Figure 1-Figure 10 The power connection assembly 380 further includes a second slide groove 384 provided in the rotating disk 310, the first insulating seat 362 and the second insulating seat 372 are both slidably connected in the second slide groove 384, an insulating bracket 385 is provided on the third insulating seat 381, and the first terminal 364 and the second terminal 374 are slidably connected to the insulating bracket 385;

[0095] A knob 386 is rotatably provided on the turntable 310 , a gear 387 is provided on the knob 386 , racks 388 are provided on both the first insulating seat 362 and the second insulating seat 372 , and both racks 388 are meshed with the gear 387 .

[0096] In this embodiment: In the prior art, when the bubble of the long level 320 is observed by human eyes, it is only a relatively centered range. In the present invention, the sliding piece 322 drives the power strip 383 to be within the range of the third insulating seat 381, and does not contact the first metal rod 363, the first terminal 364, the second metal rod 373, and the second terminal 374. The size of this range is the measurement accuracy.

[0097] And this precision can be adjusted. The insulated first insulating seat 362 and the second insulating seat 372 are slidably mounted on the front and rear ends of the third insulating seat 381, and the first terminal 364 and the second terminal 374 are also insulated and isolated by the insulating bracket 385 supporting them. By turning the knob 386 counterclockwise, the rack 388 and the second insulating seat 372 on the rear side can be moved to the left, and the rack 388 and the first insulating seat 362 on the front side can be moved to the right, reducing the distance between the first terminal 364 and the second terminal 374, and reducing the distance between the first metal rod 363 and the second metal rod 373. The sliding piece 322 drives the power connection piece 383 to move forward and backward, and the distance that keeps the circuits of the first drive assembly 360 and the second drive assembly 370 disconnected is reduced, that is, the measurement accuracy is improved. Similarly, turning the knob 386 clockwise drives the distance between the first insulating seat 362 and the second insulating seat 372 to increase, reducing the measurement accuracy.

[0098] In addition, it should be noted that, for another use of the compass, when measuring the position of the destination, when measuring the slope angle of the target object, the bubble of the long level 320 is also centered, and automatic measurement can also be performed through this device.

[0099] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0100] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
