Description

Technical Field

[0001] This utility model belongs to the field of measuring instrument technology, specifically relating to a portable borehole measuring instrument. Background Technology

[0002] Borehole measuring instruments are specialized equipment used to measure and monitor various parameters of a borehole during drilling operations. They are widely used in geological exploration, mining, construction engineering, and oil and gas drilling. However, existing borehole measuring instruments have many shortcomings. First, their dispersed functions and non-modular design lead to low measurement efficiency and insufficient adaptability to different scenarios. When conducting tunnel advance prediction and detection, before data acquisition, parameters such as borehole depth, inclination angle, height, and explosive charge depth must be measured. In particular, the installation quality of the receiving hole has a significant impact on the accuracy of data acquisition. In the past, each data point was usually measured separately, resulting in relatively low work efficiency and quality, requiring a large number of inspection personnel, and affecting the overall inspection progress. Especially when the rock conditions inside the borehole are complex, it is difficult to improve work efficiency without a full understanding of the borehole conditions. Second, the fragile structure and lack of protection of the measuring rod lead to decreased measurement accuracy and frequent equipment failures. Traditional measuring rods use ordinary stainless steel hollow tubes, which have insufficient bending strength. When the hole depth exceeds a certain distance, the tilt angle measurement error will increase, which will not meet the accuracy requirements of tunnel engineering. In addition, the torsional stiffness of the measuring rod is insufficient. When it encounters gravel in the hole, it is easy to cause angular distortion, which will lead to the breakage of the internal wires and require frequent return to the factory for repair. Furthermore, when the existing instrument's measuring end is directly exposed, the lens will become blurry due to dust accumulation when operating in a dusty environment. In the case of water inrush in the tunnel, mud and water will enter the measuring end and cause a short circuit in the camera circuit. Summary of the Invention

Detailed Implementation

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, but the present invention is not limited to these embodiments.

[0025] Example 1

[0026] exist Figures 1-10 This utility model relates to a portable drilling and measuring instrument, including a receiving rod 1, which is a hollow steel tube. A mobile power supply 2 is provided on one outer surface of the receiving rod 1, which powers a lighting assembly 18 and a camera 19.

The wireless rangefinder 7 has a panel 8 and a laser light 9. The light emission direction of the laser light 9 is parallel to the center line of the receiving rod 1. A fixing base 3 is fixedly connected to the other outer surface of the receiving rod 1. An inclinometer 5 is installed on the fixing base 3. The inclinometer 5 is an inclinometer with wireless transmission function. To ensure the stability of the connection, the fixing base 3 has four corners with snap-fit ​​grooves 4. A pawl snap-fit ​​6 is provided on one side of the inclinometer 5 corresponding to the snap-fit ​​grooves 4. The pawl snap-fit ​​6 is engaged in the snap-fit ​​grooves 4.

[0027] A reducing connector 25 is threaded onto one end of the receiving rod 1, and a rear measuring rod 10 is installed on the other end of the reducing connector 25. The reducing connector 25 is used to connect these two components of different diameters. A measuring head 16 is provided at the end of the rear measuring rod 10. An illumination group 18 and a high-definition camera 19 are installed inside the measuring head 16. One end of the measuring head 16 is open, and the other end is closed. A ring of light grooves 20 is machined on the closed end of the measuring head 16, and a mounting groove 21 is machined at the center. The illumination group 18 is fitted into the light grooves 20, and the high-definition camera 19 is fitted into the mounting groove 21. The illumination group 18 provides stable illumination to ensure that the high-definition camera 19 can clearly capture the image inside the borehole. Through the real-time image of the high-definition camera 19, the operator can intuitively see the optimal loading position or receiver installation point inside the borehole, avoiding blind operation. A dust cover 23 is provided on the outside of the measuring head 16. The dust cover 23 is made of transparent material and can effectively prevent dust accumulation on the camera lens, avoiding misjudgment of the situation inside the borehole due to blurred image. Specifically, a second external thread 22 is machined on the outer wall of one end of the measuring head 16, and a second internal thread 24 is machined inside the dust cover 23 corresponding to the second external thread 22. The dust cover 23 is fixed to the measuring head 16 by the cooperation of the second external thread 22 and the second internal thread 24.

[0028] To accommodate different hole depths, a front measuring rod 13 is provided between the rear measuring rod 10 and the measuring head 16. Multiple sets of front measuring rods 13 can be configured according to the hole depth. Specifically, one end of the rear measuring rod 10 has an internal thread 11, and the corresponding end of the front measuring rod 13 has an external thread 14 that matches the internal thread 11. The external thread 14 and the internal thread 11 are engaged to securely connect the front measuring rod 13 and the rear measuring rod 10. The friction generated by the engagement of the helical grooves effectively resists the impact on the instrument during measurement. The axial tensile force and radial torque; the rear measuring rod 10 and the front measuring rod 13 are hollow tubular structures, and each tube is fitted with a tubular cross reinforcing rib 12, changing the single cross section of the traditional hollow tube into four closed fan-shaped cross sections, which significantly improves the structural rigidity; the other end of the front measuring rod 13 is provided with a first external thread 15, and the other end of the measuring head 16 is machined with a first internal thread 17 at the position corresponding to the first external thread 15, and the front measuring rod 13 and the measuring head 16 are fastened together by the first external thread 15 and the first internal thread 17.

[0029] The working principle of this utility model is as follows:

[0030] When using this utility model, first connect the mobile power supply 2 to the lighting assembly 18 and the high-definition camera 19 via wires. Then, snap the pawl buckle 6 on the surface of the inclinometer 5 into the buckle groove 4 on the outer wall of the fixed base 3. Magnetically connect the wireless rangefinder 7 to the outer wall of the receiving rod 1. The laser light 9 on the wireless rangefinder 7 measures the distance, and the parameters are displayed on the display panel 8. The rear measuring rod 10 is connected to the receiving rod 1 via a reducing connector 25. The front measuring rod 13 and the rear measuring rod 10 are threaded together via an internal thread 11 and an external thread 14. Both the rear measuring rod 10 and the front measuring rod 13 are fitted with tubular cross reinforcing ribs 12. The front measuring rod 13 connects to the measuring head 16 via a... An external thread 15 and a first internal thread 17 are threaded together. The lighting group 18 and the high-definition camera 19 set inside the measuring head 16 are respectively fitted into the lamp slot 20 and the mounting slot 21. The measuring head 16 and the dust cover 23 are threaded together by a second external thread 22 and a second internal thread 24. The high-definition camera 19 cooperates with the lighting group 18 to capture images inside the hole in real time and transmit the video signal to the receiving end. The tubular cross reinforcing rib 12 set inside ensures the rigidity of the structure. The wireless rangefinder 7 measures the hole depth by emitting an infrared beam, and the inclinometer 5 senses the drilling inclination angle in real time. Through visual detection and dual-parameter synchronous measurement, the traditional step-by-step measurement is transformed into an integrated operation.
