Technical Field

[0001] This utility model relates to the field of tunnel surrounding rock support technology, specifically a tunnel surrounding rock precision support inspection device. Background Technology

[0002] Maintaining smooth roadways and stable surrounding rock through roadway support is crucial for coal mine construction and production. The basic purpose of roadway support is to mitigate and reduce the movement of surrounding rock, preventing excessive reduction in the roadway cross-section and preventing the collapse of loosened and damaged surrounding rock. Before anchor bolt support, holes need to be drilled in the foundation pit or cofferdam base according to design requirements. At this time, support inspection equipment is needed to observe the internal condition of the holes. However, the existing roadway surrounding rock precision support inspection equipment is prone to dust accumulation on the camera lens surface during use, affecting normal operation. Therefore, improvements are needed to address these issues and meet actual usage requirements. Utility Model Content

The air frame 301 is fixedly connected, and the air inlet frame 301 is fixedly connected to the upper side of the viewing camera 4. The extension and retraction of the electric telescopic rod 201 facilitates the lifting and lowering of the viewing camera 4 and the ultrasonic detection component 6 below, thereby pushing the viewing camera 4 and the ultrasonic detection component 6 out of the mounting cylinder 1 into the roadway surrounding rock support pit. The viewing camera 4 and the monitoring lens 5 facilitate image acquisition of the roadway surrounding rock support pit. The first motor 202 and the first rotating shaft 203 facilitate the rotation of the viewing camera 4 and the monitoring lens 5. The high-resolution monitoring lens 5 transmits images or videos of the borehole interior in real time, allowing observation of dynamic information such as borehole wall structure and fault fractures.

[0022] Please see Figures 2-3The dust removal assembly 3 includes an air inlet frame 301, an air inlet 302, a miniature suction pump 303, an air supply pipe 304, an air supply chamber 305, and a nozzle 306. The air inlet 302 is located on one side of the air inlet frame 301, and the miniature suction pump 303 is installed on the other side of the viewing camera 4. One side of the miniature suction pump 303 is connected to the air supply pipe 304, and the air supply chamber 305 is fixed to the other side of the air supply pipe 304. A nozzle 306 is located on the lower side of the air supply chamber 305. The air inlet frame 301 is interconnected with the interior of the air supply chamber 305 through the miniature suction pump 303 and the air supply pipe 304. The air supply chamber 305 is located above the monitoring lens 5 and supplies air... The chamber 305 has an arc-shaped structure, and seven nozzles 306 are evenly distributed on the lower side of the air supply chamber 305. The air inlet 302 has a filter-like ventilation structure to facilitate the filtration of the gas entering the air inlet frame 301. The filtered gas inside the air inlet frame 301 is easily sent into the air supply chamber 305 through the miniature air pump 303 and the air supply pipe 304. The air supply chamber 305 is located above the monitoring lens 5, so that the surface of the monitoring lens 5 of the spy camera 4 can be cleaned by spraying air through the nozzles 306 evenly distributed on the lower side of the arc-shaped air supply chamber 305, thereby avoiding the problem of dust adhering to the surface of the monitoring lens 5 affecting image acquisition.

[0023] Please see Figure 1 , Figure 2 and Figure 4 An ultrasonic detection assembly 6 is mounted on the lower side of the voyeur camera 4. The ultrasonic detection assembly 6 includes a second motor 601, a second rotating shaft 602, and a rotating plate 603. The second rotating shaft 602 is located below the second motor 601, and the rotating plate 603 is fixed to the bottom of the second rotating shaft 602. The ultrasonic detection assembly 6 also includes ultrasonic ranging sensors 604. The rotating plate 603 has a circular structure, and six ultrasonic ranging sensors 604 are evenly distributed in an array on its outer side. A connecting rod 7 is fixed to the lower middle part of the rotating plate 603, and a base plate 8 is fixed to the bottom of the connecting rod 7. Plate 8 has a conical structure; the second motor 601 and the second rotating shaft 602 facilitate the rotation of the rotating plate 603 to adjust the orientation of the six ultrasonic ranging sensors 604 on the outside of the rotating plate 603. The ultrasonic ranging sensors 604 can measure distance by emitting and receiving ultrasonic echoes, so that the ultrasonic ranging sensors 604 can rotate to perform all-round ultrasonic ranging inside the roadway surrounding rock support pit, thereby obtaining a three-dimensional ultrasonic image of the inside of the roadway surrounding rock support pit. With the use of the viewing camera 4 and the monitoring lens 5, the data collection of the borehole interior is more comprehensive.

[0024] In use, the mounting cylinder 1 can first be lowered into the support pit using a bracket. Then, the extension and retraction of the electric telescopic rod 201 can drive the lifting and lowering of the viewing camera 4 and ultrasonic detection component 6, pushing the viewing camera 4 and ultrasonic detection component 6 out of the mounting cylinder 1 into the roadway surrounding rock support pit. At this time, the viewing camera 4 and monitoring lens 5 can acquire images of the roadway surrounding rock support pit. The first motor 202 and the first rotating shaft 203 can also facilitate the rotation of the viewing camera 4 and monitoring lens 5. The high-resolution monitoring lens 5 can transmit images or videos of the borehole interior in real time, allowing observation of the borehole wall structure. The system can collect dynamic information such as faults and fissures. In addition, the second motor 601 and the second rotating shaft 602 can drive the rotating plate 603 to rotate, thereby adjusting the orientation of the six ultrasonic ranging sensors 604 on the outside of the rotating plate 603. The ultrasonic ranging sensors 604 can measure distance by emitting and receiving ultrasonic echoes, so that the ultrasonic ranging sensors 604 can rotate to perform all-round ultrasonic ranging inside the roadway surrounding rock support pit, thereby obtaining a three-dimensional ultrasonic image of the inside of the roadway surrounding rock support pit. With the use of the viewing camera 4 and the monitoring lens 5, the data collection of the borehole interior is more comprehensive.

[0025] During use, when dust adheres to the surface of the monitoring lens 5 of the spy camera 4 and needs to be cleaned, the dust removal component 3 can be used. At this time, the air inlet 302 has a filter-like ventilation structure that can filter the gas entering the air inlet frame 301. Then, the filtered gas inside the air inlet frame 301 is sent into the air delivery chamber 305 through the micro air pump 303 and the air delivery pipe 304. The air delivery chamber 305 is located above the monitoring lens 5. The surface of the monitoring lens 5 of the spy camera 4 can be cleaned by air jetting through the air jet nozzles 306 evenly distributed on the lower side of the arc-shaped air delivery chamber 305, thereby avoiding the problem of dust adhering to the surface of the monitoring lens 5 affecting image acquisition. Conversely, when not in use, the electric telescopic rod 201 is raised. At this time, the bottom plate 8 can seal the bottom surface of the mounting cylinder 1, thereby protecting the internal structure of the mounting cylinder 1. This is the working principle of the precision support spy camera for roadway surrounding rock.
