Description
Technical Field
[0001] This utility model relates to the field of geological inspection, and in particular to a coal mine geological inspection device. Background Technology
[0002] Before coal mining, in order to ensure mining safety and understand the geological structure, it is necessary to use a coal mine geological inspection device to extend the viewing lens into the borehole through a transmission cable, and transmit the geological image data collected by the viewing lens in the borehole to the main control host, so as to realize the visualization of the coal mine geological conditions.
[0003] Due to geological conditions and drilling techniques, coal mine borehole walls often have irregular structures such as protrusions and sharp edges. During insertion, the viewing lens is highly susceptible to collision or scratching against these protruding walls and edges. Existing coal mine geological inspection devices often lack effective collision protection structures for their viewing lenses, or only have simple fixed protective sleeves. These sleeves not only have poor cushioning performance but also cannot adapt to the complex collision angles within the borehole. Once a collision occurs, the lens cover is easily broken, and the lens chip is damaged, leading to imaging failures, hindering the smooth progress of geological inspection work, and delaying construction progress. Therefore, we designed a coal mine geological inspection device to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a coal mine geological inspection device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a coal mine geological inspection device, comprising a main control host, a transmission cable, a support unit and a viewing unit, wherein the support unit is used to support the transmission cable, the viewing unit is disposed at one end of the transmission cable, the viewing unit transmits data to the main control host through the transmission cable, and the viewing unit includes a viewing lens and an anti-collision component, wherein the anti-collision component is disposed below the viewing lens;
[0006] The anti-collision component includes a protective sleeve and an anti-collision base. The protective sleeve is disposed on the outer wall of the anti-collision base. A buffer block is fixedly connected below the anti-collision base. The buffer block is provided with a plurality of balls arranged in a circumferential array.
[0007] When encountering a protruding hole wall inside the borehole, the ball bearings first reduce the impact force, and then the hole wall pushes the anti-collision base from below, causing the protective sleeve to move upward to protect the viewing lens.
[0008] Preferably, a rubber soft sleeve is fixedly fitted onto the outer wall of the protective sleeve, and the outer wall of the rubber soft sleeve has multiple arc-shaped grooves, which are used to engage the protruding edges inside the hole wall.
[0009] Preferably, the inner wall of the protective sleeve is fixedly connected with multiple T-shaped sliders, and the outer wall of the anti-collision base is provided with multiple T-shaped grooves, and the T-shaped sliders are slidably connected in the T-shaped grooves.
[0010] Preferably, a limiting block is fixedly connected to the top of the T-shaped slider, and the limiting block overlaps above the anti-collision base to prevent the protective sleeve from falling off the outer wall of the anti-collision base.
[0011] Preferably, the buffer block is configured as a frustum shape, and the frustum surface of the buffer block has a plurality of ball holes arranged in a circumferential array. The ball is rolled and connected in the ball holes, and the inner diameter of the ball hole is larger than the aperture of the surface of the buffer block, so that the ball can roll stably in the ball hole.
[0012] Preferably, the diameter above the buffer block is smaller than the diameter of the anti-collision base.
[0013] Preferably, the viewing lens includes a connector, the top of which is fixedly connected to a transmission cable, the bottom of which is fixedly connected to a mounting base, the bottom of which is fixedly connected to a glass cover, the bottom of which is fixedly connected to the top of an anti-collision base, and the glass cover is located inside the protective sleeve.
[0014] Preferably, the support unit includes a triangular bracket, a connecting seat is fixedly connected to the top of the triangular bracket, a support block is fixedly connected to the top of the connecting seat, a pulley group is fixedly connected to the outer wall of the support block, the pulley group consists of two large pulleys and two small pulleys, and the transmission cable is slidably connected to the pulley group.
[0015] The technical effects and advantages of this utility model are as follows:
[0016] This invention establishes a multi-layered and highly efficient protection system for voyeuristic lenses, significantly improving protection effectiveness. When the voyeuristic unit encounters a protruding hole wall within the drilled hole, the ball bearings at the bottom of the buffer block first contact the protrusion, replacing sliding friction with rolling friction, greatly reducing the impact force and preventing the hole wall protrusion from directly striking the voyeuristic lens. Simultaneously, the hole wall pushes the anti-collision base from below, causing the protective sleeve to move upward along the T-shaped groove, quickly enveloping and protecting the glass cover of the voyeuristic lens. This effectively isolates the lens from scratches and collisions caused by the hole wall protrusions and sharp edges. Combined with the arc-shaped groove of the rubber soft sleeve to engage the protruding sharp edges, the protective cover protects the voyeuristic lens throughout the collision phase, comprehensively reducing the risk of lens damage.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] This utility model provides, for example Figures 1-5The illustrated coal mine geological inspection device includes a main control unit 1, a transmission cable 2, a support unit 3, and a viewing unit 4. The support unit 3 supports the transmission cable 2. The viewing unit 4 is located at one end of the transmission cable 2 and transmits data to the main control unit 1 via the transmission cable 2. The viewing unit 4 includes a viewing lens 41 and an anti-collision component 42. The anti-collision component 42 is located below the viewing lens 41 and includes a protective sleeve 421 and a protective shield. The anti-collision base 422 has a protective sleeve 421 disposed on its outer wall. A rubber soft sleeve 425 is fixedly sleeved on the outer wall of the protective sleeve 421. The outer wall of the rubber soft sleeve 425 has multiple arc-shaped grooves 426 for engaging protruding edges inside the hole wall. Multiple T-shaped sliders 427 are fixedly connected to the inner wall of the protective sleeve 421. The outer wall of the anti-collision base 422 has multiple T-shaped sliding grooves 428, and the T-shaped sliders 427 are slidably connected to the T-shaped sliding grooves. Inside 428, a limiting block 429 is fixedly connected to the top of the T-shaped slider 427. The limiting block 429 overlaps the anti-collision base 422 to prevent the protective sleeve 421 from falling off the outer wall of the anti-collision base 422. A buffer block 423 is fixedly connected to the bottom of the anti-collision base 422. The buffer block 423 is provided with a plurality of balls 424 arranged in a circumferential array. The buffer block 423 is shaped like a frustum, and a plurality of balls arranged in a circumferential array are formed on the frustum surface of the buffer block 423. The ball bearing 424 is rotatably connected to the ball hole 4210. The inner diameter of the ball hole 4210 is larger than the aperture of the surface of the buffer block 423, so that the ball bearing 424 can roll stably in the ball hole 4210. The diameter of the buffer block 423 is smaller than the diameter of the anti-collision base 422. When encountering a protruding hole wall in the drill hole, the ball bearing 424 first reduces the collision force with it, and then the hole wall pushes the anti-collision base 422 from below, causing the protective sleeve 421 to move upward to protect the viewing lens 41.
[0027] like Figure 6 As shown, as a technical optimization of this utility model, the viewing lens 41 includes a connecting connector 411. The top of the connecting connector 411 is fixedly connected to the transmission cable 2, and the bottom of the connecting connector 411 is fixedly connected to a mounting base 412. The bottom of the mounting base 412 is fixedly connected to a glass cover 413. The bottom of the glass cover 413 is fixedly connected to the top of the anti-collision base 422. The glass cover 413 is located inside the protective sleeve 421. This mechanism is used to capture real-time images of the rock structure, cracks, etc. of the coal mine borehole wall.
[0028] like Figure 7As shown, as a technical optimization of this utility model, the support unit 3 includes a triangular bracket 31, a connecting seat 32 fixedly connected to the top of the triangular bracket 31, a support block 33 fixedly connected to the top of the connecting seat 32, and a pulley group 34 fixedly connected to the outer wall of the support block 33. The pulley group 34 consists of two large pulleys and two small pulleys. The transmission cable 2 is slidably connected to the pulley group 34. This structure provides stable support and guidance for the transmission cable 2, allowing the transmission cable 2 to slide smoothly, thereby facilitating the smooth insertion of the viewing unit 4 into the coal mine borehole.
[0029] In use, the triangular bracket 31 of the support unit 3 is first unfolded and fixed, so that the transmission cable 2 is placed on the pulley block 34 for support and guidance. Then, the viewing unit 4 with the anti-collision component 42 is slowly lowered into the coal mine borehole through the transmission cable 2. During the lowering process, if the buffer block 423 at the bottom of the anti-collision component 42 encounters a protrusion on the borehole wall, the ball 424 in its ball hole 4210 will first contact the protrusion and roll to reduce the impact force. Then, the protrusion continues to act on the buffer block 423 and pushes the anti-collision base 422 upward from below. At this time, the protective sleeve 421 moves upward along the T-shaped slide groove 428 of the anti-collision base 422 through the inner wall T-shaped slider 427 until it forms a protective cover for the inner viewing lens 41. At the same time, the arc-shaped slot 426 of the rubber soft sleeve 425 on the outer wall of the protective sleeve 421 can engage the protruding corner of the borehole wall, so that the protective cover protects the viewing lens 41 throughout the collision stage, achieving full anti-collision protection for the viewing lens 41.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
