Description

Technical Field

[0001] The invention relates to the technical field of geological exploration, and in particular to a precise azimuth measuring device for uranium ore drilling. Background Art

[0002] In uranium geological exploration and drilling, measuring the azimuth of the drill hole is an indispensable step. The traditional method of measuring the azimuth of the drill hole is to use a combination of a measuring rope and a geological compass, that is, the thin rope is straightened close to the drill, kept parallel to the drill beam and extended outward, away from the interference of surrounding iron objects, and the surveyor uses a geological compass to stick to the edge of the thin rope, so that one side of the long axis of the geological compass is parallel to the thin rope, and the azimuth value is measured and recorded when the compass level bubble is centered.

[0003] The traditional method of measuring azimuth requires the collaboration of multiple people, and in the process of adjusting the parallelism of the drill rig, measuring rope and compass through handheld operation, it is difficult to install the measuring device horizontally at the azimuth position to be measured. At the same time, it is very easy to be shaken or shaken during measurement, resulting in inaccurate azimuth measurement, large errors and low test efficiency, which increases the limitations of the use of the device, and the measurement structure is not easy to perform more detailed height adjustment. The structure for measuring azimuth is generally exposed to the outside, which is not only easily interfered by external substances, further reducing the measurement accuracy of the azimuth, but also difficult to store before and after measurement, which increases the difficulty and inconvenience of carrying the device.

[0016] Compared with the prior art, the present invention provides a precise azimuth angle measuring device for uranium ore drilling, and has the following beneficial effects:

[0017] 1. Through the structural cooperation of the infrared emission and reception device and the infrared reflection and display device, the present invention can utilize the emitted infrared rays to be correspondingly reflected and matched, so as to make the two spirit levels centered, thereby judging that the reflection device is in a completely horizontal state. Through the reception cooperation of the infrared emission and reception unit, after receiving the horizontal infrared light, total reflection will occur, and the light will return along the original path to the reception device. At this time, read the azimuth angle displayed by the electronic compass in real time, or use the flat area on the upper part of the compass to lean against the reflection device to accurately measure the azimuth angle. Using infrared rays instead of traditional measuring ropes improves the extensibility, stability and accuracy. Using the principle of total reflection of light and the advanced electronic compass to display the azimuth angle in real time eliminates the human operation and reading errors, and at the same time maximally eliminates the magnetic field interference brought by the surrounding iron objects.

[0018] 2. By utilizing the structural cooperation of the housing, the present invention can uniformly store and protect the infrared reflection display device and the infrared emission and reception device for azimuth angle measurement work, so as to take them out for measurement work when the structure is used, and enable the device to perform infrared calibration under the protection structure of the housing. Through the independent height fine adjustment of the infrared emission and reception device and the height adjustment of the two groups of telescopic support rods provided below the infrared reflection display device to cooperate with each other, so that the two measurement structures can be adjusted according to different terrains, greatly increasing the flexibility and convenience of the device measurement work. And through the ° rotation of the infrared reflection device, and at the same time adding telescopic support rods, the operability and practicality of the overall device are ensured.

[0019] 3. Through two groups of magnetic block magnetic attraction structures arranged on the end face of the outer shell of the present invention, it can be adsorbed on the end face of the ground beam for pre-positioning, abandoning the cumbersome operation processes such as using screws to drill holes in traditional devices. Four groups of sleeves and positioning plates are used to expand outward synchronously under the limit of the sleeve rod, so as to make structural extensions according to ground beams with different widths. Furthermore, through the fitting contact between the four groups of positioning plates and the inner wall of the ground beam, the outer shell can be effectively and stably structurally fixed, and the position of the outer shell adsorbed on the surface of the ground beam can be automatically corrected, avoiding the inclination of the outer shell from affecting the measurement operations of the infrared reflection display device and the infrared emission and reception device, and increasing the convenience of structural installation and the working efficiency of measurement operations.

[0039] As a preferred solution of this embodiment: The telescopic support rod 403 is composed of four single sections, and the end of the telescopic support rod 403 is in a pointed cone shape, so that the unfolded telescopic support rod 403 can be embedded in the ground to position the entire mounting plate 401.

[0041] Embodiment 1, as Figure 1-4 shown, through the mutual cooperation of the infrared emission, reflection and light reception structures of the infrared reflection display device 4 and the infrared emission and reception device 6, it is convenient to measure the azimuth angles of different geological conditions, and greatly reduces the manpower. The infrared light beam is used instead of the traditional measuring rope, which has better ductility, parallelism and stability. At the same time, by virtue of the total reflection principle of light and the electronic compass to display the azimuth angle in real time, the human operation error is greatly reduced, and it is more accurate and efficient.

[0042] Embodiment 2, as Figure 1-2 and Figure 8 shown, when the device is installed on the ground beam 1, the entire housing 2 can be directly adsorbed on the inner wall surface of the ground beam 1 through two groups of magnetic blocks 7. Then, by starting the driver 14, the bevel gear set 15 is engaged and linked to force the bidirectional lead screw 12 to rotate. Then, the two inner threaded tubes 16 are driven by the bidirectional lead screw 12 to move away from each other horizontally, causing the two inner threaded tubes 16 to drive the movable plate 13 and the sleeve 10 to expand. The four sleeves 10 are simultaneously extended vertically upward and downward under the limit cooperation of the sleeve rods 11. Thus, the positioning plate 9 is driven by the four sleeves 10 to expand and contact the inner wall of the ground beam 1 simultaneously, thereby automatically correcting the position of the housing 2 and ensuring that the housing 2 is accurately and stably fixed in the ground beam 1, preventing the device from tilting and shifting during measurement due to vibration, increasing the convenience of the installation operation of this structure, and improving the accuracy and stability of azimuth measurement.

[0043] Working principle: When performing the azimuth measurement of uranium ore drilling, the ground beam 1 is connected to the foundation or cement, and a machine platform is set on the upper part of the ground beam 1, thereby fixing the ground beam 1 and the machine platform to prevent displacement or deviation during the drilling process and increasing the accuracy of the azimuth of the ground beam and the opening azimuth of the borehole;

[0044] Before use, the device is magnetically positioned on the inner wall of the side of the ground beam 1 through two groups of magnetic blocks 7, and the pull-out door 5 is opened. The internally placed infrared reflection display device 4 is taken out and unfolded as a whole. At this time, the slider 4014 can be horizontally moved inside the chute 4010, causing the hinge seat 407 and the mounting bracket 406 to move to the outermost side of the mounting plate 401. Then, the slider 4014 can be positioned. Then, manually rotate the handle 405 to drive the first gear 4011 to rotate and mesh with the second gear 4013, causing the second gear 4013 to drive the rotating shaft 4012, the hinge seat 407, and the mounting plate 401 to rotate as a whole for 360° angle adjustment. Then, pull out the two telescopic support rods 403 for height adjustment and embed the two telescopic support rods 403 into the ground, so that the telescopic support rods 403 support the mounting plate 401 stably. At this time, manually rotate the threaded rod 305 to drive the internally threaded sleeve block 304 to move up and down for fine adjustment, causing the internally threaded sleeve block 304 to drive the mounting seat 303 and the internally mounted infrared emission and reception device 6 to move up and down slightly, so that the infrared reflection display device 4 and the infrared emission and reception device 6 are horizontally aligned. And the movement of the internally threaded sleeve block 304 drives the pointer 306 to move synchronously, so as to observe the height through the scale plate 301. Thus, the infrared emission and reception device 6 is accurately and stably adjusted inside the housing 2, and the interference of external objects during the measurement work is prevented, increasing the protection of the structure;

[0045] When performing the azimuth measurement, infrared rays can be emitted from the mounting head 605 by starting the infrared emission and reception unit 604. At this time, the emission indicator light 602 normally lights green. After the emitted infrared rays are on the same horizontal plane as the circular reflection area 408, the observation beam light is observed for horizontality through the setting of the three sets of spirit levels 404. Then, by using the total reflection of the circular reflection area 408, the light is folded back and received by the infrared emission and reception unit 604. During this period, when the reception indicator light 603 normally lights red, it is regarded as normal reception. And at this time, the azimuth angle displayed by the electronic compass 402 is the azimuth angle of the destination. The azimuth angle and other information are displayed in real time under the control of the central processing unit 4015 by using the display screen 409. It is also possible to perform settings and data storage by touching the screen, so as to accurately and stably complete the azimuth measurement work, and increase the flexibility and accuracy of the azimuth measurement operation of the device.

[0046] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than a limitation on the protection scope of the present invention. Any simple modification or equivalent replacement of the technical solution of the present invention by those of ordinary skill in the art shall not depart from the essence and scope of the technical solution of the present invention.
