Description

Technical Field

[0001] The invention relates to the technical field of mine exploration drilling measurement and positioning, and in particular to a drilling rig hole orientation measurement device based on a six-axis MEMS sensor. Background Art

[0002] During the exploration and mining process of mines, drilling operations are an indispensable means. Exploration drilling can determine the reserve status of the ore body and whether it is worth mining. During mining, drilling can clarify the distribution of mineral deposits, rocks, and aquifers, providing a basis for geological analysis and safe production of mines. The azimuth and inclination of the borehole are important factors in drilling positioning. At present, most of the drilling angle positioning still uses on-site hanging lines and angle rulers to adjust the azimuth and inclination. During the operation, the angle alignment and degree reading are greatly affected by human factors, and the angle accuracy is difficult to guarantee. The real-time working condition record of the drilling is not accurate and complete. Therefore, a simple, practical, accurate, safe, and fully functional mining drill hole directional measurement and display device is of great significance to the efficiency and accuracy of drilling positioning.

[0008] In view of the problems of poor anti-interference, high cost, low precision and large human influence factors in the prior art, the present invention provides a drilling rig hole directional measurement device based on a six-axis MEMS sensor, which has two terminal devices, is flexible to use and easy to install. Through the coordinated use of a laser module and a six-axis MEMS sensor module, the measurement accuracy and anti-interference performance are improved, and the influence of human factors is reduced, while the cost is low.

[0009] The following is the technical solution of the present invention.

[0010] A drilling rig hole directional measurement device based on a six-axis MEMS sensor, including an orientator and a patrol meter connected to the orientator in communication, the orientator and the connecting sleeve of the drilling rig drill rod are detachably connected, the patrol meter is a handheld terminal provided with a display module and buttons, the orientator is provided with two mutually perpendicular openings, a laser module is provided in the openings, a six-axis MEMS sensor module and a mainboard are also provided in the orientator, and the laser module and the six-axis MEMS sensor module are connected to the mainboard. The present invention is provided with two terminals, which are flexible to use and easy to install. The orientator is the main measuring component, and the required angle and other information are obtained through the laser module and the six-axis MEMS sensor module. The patrol meter is a handheld terminal, which can remotely control the orientator and display corresponding data.

[0011] Furthermore, the orientation tool is a rectangular parallelepiped, the first opening is arranged on the bottom surface of one end of the rectangular parallelepiped, the second opening is arranged on a side surface of the rectangular parallelepiped, the directions of the openings are perpendicular to the plane in which they are located, and the other end of the orientation tool is detachably connected to the drill pipe connecting sleeve.

[0012] Furthermore, the laser module of the orientation instrument includes an axis laser positioning module and a cross-line laser positioning module, the axis laser positioning module is aligned with the first opening, and the cross-line laser positioning module is aligned with the second opening. The cross-line laser positioning module is aligned with the top reference line of the mine tunnel to perform azimuth initialization positioning. After the initialization positioning is completed, the orientation instrument is installed on the connecting sleeve, and the light spot of the axis laser positioning module coincides with the drilling point of the mine working surface to obtain an accurate drilling angle. The module has strong anti-interference, high precision and low cost.

[0013] Furthermore, the cross-line laser positioning module includes a transmitting end and a total reflection mirror, the transmitting end is connected to the mainboard, the transmitting direction of the transmitting end is opposite to the transmitting direction of the axis laser positioning module, the total reflection mirror is located in front of the transmitting end, and the emission direction of the total reflection mirror is aligned with the second opening. Since the internal space of the orientation instrument is limited, if the emission direction of the transmitting end of the cross-line laser positioning module is directly aligned with the second opening, it will result in that the entire orientation instrument cannot be accommodated or the volume is too large after accommodating. Therefore, when designing, the emission direction of the transmitting end is consistent with the emission direction of the axis laser positioning module, and then it is emitted by means of a total reflection mirror, which can effectively utilize the internal space without affecting actual use.

[0014] Furthermore, the orientation instrument is also provided with a display module and a key module, which are arranged on the side where the second opening is located, and the display module and the key module are connected to the main board. The orientation instrument is also provided with a display module and a key module, which can be separated from the inspection instrument for independent operation in some cases, which is convenient and fast, and improves applicability.

[0015] Furthermore, the orientation instrument is provided with a plurality of pillars, and the main board is fixed by the pillars. The working environment of the orientation instrument has certain uncertainty. By suspending the main board by the pillars, the pillars can absorb certain vibrations, and can effectively protect the main board from damage due to collision and the like.

[0016] Furthermore, the orientation meter and the inspection meter are both provided with Bluetooth modules. The orientation meter Bluetooth module is connected to the mainboard, and the inspection meter Bluetooth module is connected to the display module and buttons. The orientation meter and the inspection meter are connected through the Bluetooth module communication.

[0017] Furthermore, the thickness of the bottom surface where the first opening of the orientation tool is located is greater than or equal to the thickness of other surfaces. The first opening is aligned with the drilling point of the mine working face when in use, so a thicker bottom surface can improve the reliability of the orientation tool.

[0018] Furthermore, the display modules of the orientation meter and the inspection meter are OLED screens.

[0019] Furthermore, the button module of the orientation instrument and the buttons of the inspection instrument are both membrane buttons.

[0025] Example: Figure 1The figure shows a drilling rig hole directional measurement device based on a six-axis MEMS sensor, including an orientator 1 and a patrol meter 2 that is communicatively connected to the orientator 1.

The orientator 1 is provided with two mutually perpendicular openings, in which a laser module is provided. The orientator 1 is also provided with a six-axis MEMS sensor module 5 and a main board 8, and the laser module and the six-axis MEMS sensor module 5 are connected to the main board 8. This embodiment is provided with two terminals, which are flexible to use and easy to install. The orientator 1 is the main measuring component, and the required angle and other information are obtained through the laser module and the six-axis MEMS sensor module 5. The patrol meter 2 is a handheld terminal that can remotely control the orientator 1 and display corresponding data.

[0026] like Figure 2 As shown, the orientation tool 1 is a rectangular parallelepiped, the first opening 12 is arranged on the bottom surface of one end of the rectangular parallelepiped, the second opening 13 is arranged on a side surface of the rectangular parallelepiped, the directions of the openings are perpendicular to the plane where they are located, and the other end of the orientation tool 1 is detachably connected to the drill pipe connecting sleeve.

The axis laser positioning module 6 is aligned with the first opening 12, and the cross-line laser positioning module 7 is aligned with the second opening 13. The cross-line laser positioning module 7 is aligned with the top reference line of the mine tunnel to perform azimuth initialization positioning. After the initialization positioning is completed, the orientation instrument 1 is installed on the connecting sleeve, and the light spot of the axis laser positioning module 6 coincides with the drilling point of the mine working surface to obtain an accurate drilling angle. The module has strong anti-interference, high precision and low cost.

[0028] In this embodiment, the cross-line laser positioning module 7 includes a transmitting end and a total reflection mirror 11, the transmitting end is connected to the main board 8, the transmitting direction of the transmitting end is opposite to the transmitting direction of the axis laser positioning module 6, the total reflection mirror 11 is located in front of the transmitting end, and the emission direction of the total reflection mirror 11 is aligned with the second opening 13. Since the internal space of the orientation instrument 1 is limited, if the emission direction of the transmitting end of the cross-line laser positioning module 7 is directly aligned with the second opening 13, it will result in that the entire orientation instrument 1 cannot be accommodated or the volume is too large after accommodating. Therefore, when designing, the emission direction of the transmitting end is consistent with the emission direction of the axis laser positioning module 6, and then emitted by means of the total reflection mirror 11, which can effectively utilize the internal space without affecting the actual use.

The orientation instrument 1 is also provided with a display module 3 and a key module 9, which can be separated from the inspection instrument 2 for independent operation in some cases, which is convenient and fast, and improves applicability.

[0030] In this embodiment, the orientation instrument 1 is provided with a plurality of pillars, and the main board 8 is fixed by the pillars. The working environment of the orientation instrument 1 has certain uncertainty, and the main board 8 is suspended by the pillars, and the pillars can absorb certain vibrations, which can effectively protect the main board 8 and prevent damage due to collision and other reasons.

[0031] In this embodiment, the orientation meter 1 and the inspection meter 2 are both provided with a Bluetooth module 10. The Bluetooth module 10 of the orientation meter 1 is connected to the mainboard 8, and the Bluetooth module 10 of the inspection meter 2 is connected to the display module 3 and buttons. The orientation meter 1 and the inspection meter 2 are connected for communication via the Bluetooth module 10.

[0032] In this embodiment, the bottom surface of the first opening 12 of the orientation tool 1 is thicker than the thickness of other surfaces. The first opening 12 is aligned with the drilling point of the mine working face when in use, so a thicker bottom surface can improve the reliability of the orientation tool 1.

[0034] Furthermore, the button module 9 of the orientation instrument 1 and the buttons of the inspection instrument 2 are all membrane buttons.
