Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0050] In this embodiment, as Figure 1 and Figure 2 As shown, a karst cave detection device includes a camera host 1 and a camera probe 2. The camera host 1 is connected to the camera probe 2 via a multi-core cable. A sleeve 31 is a hollow tubular structure with a cable channel inside. A flexible connection component 32 is located at one end of the sleeve 31 near the camera probe 2 and can be bent at multiple angles to adjust the orientation of the camera probe 2.

[0051] The flexible connection assembly 32 includes: a flexible tube 321, one end of which is connected to a sleeve 31, and the other end of which is connected to a fixing tube 322; the fixing tube 322 is connected to the camera probe 2 via a positioning pin 322a; a compression spring 33, which is sleeved on the outer periphery of the flexible tube 321, one end of which is fixedly connected to the fixing tube 322, and the other end of which is fixedly connected to the sleeve 31; and a pulling assembly 34, which pulls the fixing tube 322 to deflect, thereby changing the orientation of the camera probe 2.

[0052] Therefore, the camera probe 2 is installed in the fixed tube 322, and the positioning pin 322a is tightened to fix the camera probe 2 against the outer periphery. The cable connecting the camera probe 2 passes through the flexible tube 321 and the sleeve 31 in sequence and extends outward to connect with the camera host 1. When drilling holes on the arch surface of the cave for inspection, the staff can use the handwheel 311 to gradually insert the fixed tube 322 and the sleeve 31 into the hole. The camera probe 2 moves with the fixed tube 322 to inspect the inner wall of the hole. The fixed tube 322 and the sleeve 31 are connected by a compression spring 33. The orientation of the fixed tube 322 and the camera probe 2 can be changed by pulling the component 34 to facilitate multi-angle inspection of the hole or crack.

[0053] Specifically, the camera host 1 and camera probe 2 are components of the camera. The camera is a commonly used testing device in this field. The sleeve 31 is used to wrap and store the cable. The flexible tube 321 is made of rubber material to prevent the compression spring 33 from squeezing the cable when it deforms. The compression spring 33 has a certain stiffness. The design of the compression spring 33 improves the connection strength between the fixed tube 322 and the sleeve 31, so that the sleeve 31 can drive the fixed tube 322 to move (the elastic coefficient of the compression spring 33 is selected according to the specific requirements of use).

[0054] In some embodiments, such as Figure 2 As shown, the pull assembly 34 includes at least four ear plates 341, which are evenly distributed based on the fixed tube 322; each ear plate 341 is fixedly connected with a pull rope 342.

[0055] Specifically, the number of ear plates 341 used is processed according to the usage requirements. For example, the ear plates 341 are distributed in eight directions along the outer periphery of the fixing tube 322. The number of pull ropes 342 used corresponds to the number of ear plates 341. When the pull ropes 342 are used independently, they drive the fixing tube 322 to deflect in the corresponding direction.

[0056] In some embodiments, such as Figure 4 and Figure 5 As shown, the insertion angle adjustment assembly 4 includes: a circular plate 41, in which a through groove 41a adapted to the sleeve 31 is formed; a connector 411, which is used to fix the position of the sleeve 31 in the through groove 41a; two rotating shafts 42, which are symmetrically distributed based on the circular plate 41, and the ends of the two rotating shafts 42 away from the circular plate 41 are rotatably connected to the limiting wheel 43 through bearings; the limiting wheel 43 has an arc-shaped sliding groove 43a; a locking member 44, which is used to lock the deflection angle of the rotating shaft 42 in the limiting wheel 43; and a support seat 45, which is used to support the limiting wheel 43.

[0057] Specifically, the through groove 41a is used to store the sleeve 31, and the two rotating shafts 42 are located on the same axis to assist the deflection of the circular plate 41; the limiting wheel 43 is designed with two for mounting the rotating shafts 42, and the bearing seat 45 can support the overall mechanism.

[0058] In some embodiments, such as Figure 6 As shown, the locking component 44 includes: a strip plate 441, which is arranged parallel to the limiting wheel 43; one end of the strip plate 441 is fixedly connected to the rotating shaft 42, and the other end of the strip plate 441 is inserted with a bolt 442, the outer periphery of the bolt 442 passes through the strip plate 441 and the arc-shaped slide groove 43a in sequence and is connected to the nut 443.

[0059] Specifically, each shaft 42 is designed with a locking element 44, and the strip plate 441 moves along the side of the limiting wheel 43 as the shaft 42 moves. The arc-shaped groove 43a is used to constrain the stroke of the bolt 442 to limit the deflection angle of the circular plate 41 between the two shafts 42.

[0060] In some embodiments, such as Figure 7 As shown, the support base 45 includes: a rectangular frame 451, with casters 452 at each of the four corners of the rectangular frame 451; and two support plates 453, which are symmetrically distributed based on the rectangular frame 451, with the top of each support plate 453 fixedly connected to a limiting wheel 43.

[0061] Specifically, four casters 452 are used to move the rectangular frame 451, and two support plates 453 are symmetrically distributed based on the long side of the rectangular frame 451. The main body of the two support plates 453 is triangular in structure to increase the stability of the overall structure.

[0062] In some embodiments, such as Figure 7 As shown, the rectangular frame 451 is equipped with a removable pad 451a, which is used to place the camera main unit 1.

[0063] Specifically, the rectangular frame 451 has a slot that matches the pad 451a, the camera host 1 can be placed on the pad 451a, and other testing tools can also be placed on the pad 451a.

[0064] In some embodiments, such as Figure 6 As shown, the connector 411 includes: an arc-shaped clamp 411a, which is located on the same axis as the through groove 41a, and is fixedly connected to the side of the circular plate 41; the arc-shaped clamp 411a is connected to the sleeve 31 through a top pin 411b.

[0065] Specifically, the arc-shaped clamp 411a protrudes outward along the side of the circular plate 41; there are two top pins 411b with threads machined on their outer walls, and rotating the top pins 411b can fix the sleeve 31 against the arc-shaped clamp 411a.

[0066] In some embodiments, such as Figure 1 As shown, the end of the sleeve 31 away from the hose 321 is internally threaded with a handwheel 311, and the outer circumference of the handwheel 311 is machined with anti-slip texture.

[0067] Specifically, the handwheel 311 and the sleeve 31 are detachably connected. When the sleeve 31 is used independently, it is supported by the handwheel 311. After the handwheel 311 is removed, the sleeve 31 can be installed in the circular plate 41 and used in combination with the insertion angle sleeve assembly 4.

[0068] In some embodiments, such as Figure 2 As shown, the pull rope 342 is woven from at least one of aramid fiber, ultra-high molecular weight polyethylene fiber or carbon fiber, providing tensile load-bearing capacity;

[0069] Specifically, the pull rope 342 can also be made of other high-strength materials, as long as the tensile load-bearing capacity of the pull rope 342 is met.

[0070] In some embodiments, such as Figure 3 As shown, the end of the fixed tube 322 away from the flexible tube 321 is hemispherical;

[0071] It should be noted that the fixing tube 322 has a hemispherical convex surface design, which wraps around the outer periphery of the camera probe 2 to increase protection. The hemispherical arc surface design also makes it less likely for the fixing tube 322 to rub against the surrounding rocks when the orientation of the fixing tube 322 is changed.

[0072] The working principle of this application is illustrated below with a preferred embodiment:

[0073] Install the camera probe 2 in the fixed tube 322, tighten the positioning pin 322a to fix the camera probe 2 against the outer periphery. (During installation, the camera probe 2 is embedded in the fixed tube 322, and the camera of the camera probe 2 is recessed into the fixed tube 322 according to the preset length.) The cable connecting the camera probe 2 passes through the flexible tube 321 and the sleeve 31 in sequence and extends outward to connect with the camera host 1. When drilling holes on the arch surface of the cave for inspection, the staff can hold the handwheel 311 to gradually insert the fixed tube 322 and the sleeve 31 into the hole. The camera probe 2 moves with the fixed tube 322 to inspect the inner wall of the hole.

[0074] By pulling a single pulling rope 342, the pulling rope 342 causes the fixed tube 322 to shift through the ear plate 341. At this time, the compression spring 33 is deformed on one side due to the force, and the compression spring 33 causes the hose 321 to deform, thereby changing the orientation of the camera probe 2 to detect different positions of the borehole.

[0075] Remove the handwheel 311, insert the sleeve 31 into the through groove 41a of the circular plate 41, and then reconnect the handwheel 311 and the sleeve 31 with threads. Then rotate the top pin 411b to press the sleeve 31 against it. Move the entire mechanism to a suitable position by using the universal wheel 452 at the bottom of the rectangular frame 451. Rotate the shaft 42 in the two limit wheels 43. The shaft 42 causes the circular plate 41 to tilt. The circular plate 41 causes the sleeve 31 to align with the drill hole. (The deflection angle of the circular plate 41 is determined according to the cracks or drill holes on the surface of the cave arch.) Then use bolts 442 and nuts 443 to lock the strip plate 441 and the limit wheels 43 to fix the tilt angle of the circular plate 41. Then loosen the top pin 411b and move the sleeve 31 in the circular plate 41. The sleeve 31 causes the fixed tube 322 and the camera probe 2 to extend into the drill hole for inspection.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
