Description

Technical Field

[0001] This utility model provides a detection and guidance device for exploration boreholes in goaf areas, belonging to the field of geotechnical engineering exploration technology for goaf areas. Background Technology

[0002] When conducting geotechnical engineering surveys in goaf areas, borehole camera technology acquires image data of the goaf by inserting a camera into the borehole. However, due to the damage to the rock strata in the goaf, the surface of the borehole components is uneven, making it difficult for the camera lens to reach the designated location in the goaf. This is a common reason for the interruption of borehole camera work.

[0003] Chinese utility model patent (CN 211348665 U) provides a goaf detection device for detecting irregularly collapsed goaf areas. The device involves mounting a detection element on a flexible rod. During detection, if an irregularly collapsed goaf area is encountered, the flexible rod can adaptively bend to accommodate the irregularity, allowing the camera on the detection element to continue detecting the goaf by taking photos or videos. However, this goaf detection device has limited applicability. If the broken rock in the goaf is large or hard, causing the flexible rod to be unable to avoid the broken rock and thus coil up and unable to extend further downwards, the camera operation inside the borehole will still be interrupted. Utility Model Content

[0004] To address the technical problem that existing detection devices cannot effectively detect irregularly collapsed goaf areas, this invention proposes a goaf exploration borehole guidance device. The purpose is to improve the hardware structure of the goaf detection device so that the acquisition device can smoothly enter and collect data from goaf areas with collapsed rocks for detection.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a detection and guidance device for exploration holes in goaf areas, including a guiding mechanism and a fixing device. The guiding mechanism includes a drilling component, a fixing component is fixedly connected to the drilling component, and a pointed end is provided on the drilling component away from the fixing component. The fixing component is connected to the acquisition device.

[0006] The fixing device includes several adjusting bases, which are evenly arranged around the circumference of the fixing member. The adjusting bases are set on the fixing member, and adjusting members are movably connected to the adjusting bases. The adjusting bases, adjusting members and fixing members cooperate with each other to adjust the mutual cooperation relationship between the fixing member and the data acquisition device.

[0007] An anti-slip device is also provided between the fixing component and the data acquisition device, and the fixing component, the anti-slip device and the data acquisition device cooperate with each other.

[0008] Furthermore, the drilling component includes a plurality of first support rods, and the plurality of first support rods form a conical frame;

[0009] The fastener includes several second support rods, which together form a columnar structure. The bottom of the conical skeleton formed by the first support rods matches the bottom of the columnar structure formed by the second support rods.

[0010] Furthermore, the adjusting member is a resilient strip structure, and the two ends of the adjusting member cooperate with each other to adjust the area enclosed by the adjusting member.

[0011] Furthermore, the fixing component and the drilling component are an integral structure.

[0012] Furthermore, the adjusting base has a through hole, and the adjusting component is placed inside the through hole with a clearance fit between the adjusting component and the adjusting base.

[0013] Furthermore, the adjusting base has a groove, and the adjusting component is placed in the groove, with the adjusting component fitting into the groove.

[0014] Furthermore, both the first and second support rods are made of iron.

[0015] Furthermore, the adjusting component is a stainless steel cable tie.

[0016] Furthermore, the anti-slip device is made of rubber.

[0017] The advantages of this utility model over the prior art are as follows:

[0018] 1. The guiding mechanism of this utility model can smoothly send the collection device into the irregular goaf, so that the collection device can detect the goaf where rocks have collapsed.

[0019] 2. The anti-slip device of this utility model is set between the fixing part and the collection device. It works together with the fixing part to effectively prevent the guide mechanism from falling off the collection device, and at the same time avoids the collection device from rubbing against the fixing part and damaging the collection device.

[0020] 3. The adjusting and fixing parts of this utility model cooperate to firmly fix the guiding mechanism to the collection device, preventing it from falling off during drilling. Adjusting the size of the adjusting and fixing parts can make it suitable for different collection devices, making it versatile. Moreover, this utility model has a simple structure and is more economical. Attached Figure Description

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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 connection between the internal components of two elements. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] like Figures 1 to 2 As shown, this utility model provides a detection and guidance device for exploration holes in goaf areas, including a guiding mechanism 1 and a fixing device. The guiding mechanism 1 includes a drilling component 4, and a fixing component 5 is fixedly connected to the drilling component 4. A pointed end is provided on the drilling component 4 away from the fixing component 5. The fixing component 5 is connected to the acquisition device 2 and is adapted to the acquisition device 2. In this embodiment, the acquisition device 2 is a camera with a storage module.

[0028] Specifically, the drilling component 4 includes several first support rods. In this embodiment, three support rods with a length of 15cm are provided. The multiple first support rods form a conical skeleton, and the cone height is preferably 13cm. The fixing component 5 includes several second support rods, which form a columnar structure. The inner diameter of the columnar structure is the same as the diameter of the lens of the acquisition device 2, and the height of the columnar structure is preferably 10cm. The acquisition device 2 is placed inside the columnar structure of the fixing component 5. The bottom of the conical skeleton formed by the first support rods matches the bottom of the columnar structure formed by the second support rods, that is, the bottom of the drilling component 4 and the bottom of the fixing component 5 cooperate with each other. In this embodiment, the multiple first support rods form a conical structure, and the multiple second support rods form a cylindrical structure. The radius of the bottom of the drilling component 4 is the same as the radius of the bottom of the fixing component 5. The fixing component 5 and the drilling component 4 are an integral structure. Both the first support rods and the second support rods are made of iron.

[0029] The cone height of the drill bit 4 with a tapered skeleton structure and the height of the fixing part 5 with a columnar structure can be adjusted appropriately according to the working environment.

[0030] The fixing device includes several adjusting bases, which are evenly arranged around the circumference of the fixing member 5. The adjusting bases are fixedly connected to the fixing member 5. Adjusting members 6 are movably connected to the adjusting bases. Adjusting members 6 are flexible strip-shaped structures. The two ends of the adjusting members 6 cooperate to adjust the area enclosed by the adjusting members 6. The adjusting bases, adjusting members 6, and fixing member 5 cooperate to adjust the cooperation relationship between the fixing member 5 and the acquisition device 2. That is, the adjusting bases, adjusting members 6, and fixing member 5 cooperate to fix the fixing member 5 to the acquisition device 2. In this embodiment, the adjusting member 6 is a stainless steel cable tie with a width of 12.5mm, a length of 700mm, and a thickness of 0.6mm. The specifications of the stainless steel cable tie can also be adjusted according to the actual lens diameter, ensuring that the guide cap can be tied to the lens. The structure of the adjusting bases can also be set to other structures, or the adjusting bases can be omitted, and the adjusting members 6 can be directly bound to the fixing member 5, as long as they cooperate with the adjusting members 6 to adjust the area enclosed by the adjusting members 6.

[0031] An anti-slip device 3 is also fixedly connected between the fixing component 5 and the acquisition device 2. The anti-slip device 3 is a sheet-like structure, 10cm wide, and its length is the same as the circumference of the lens of the acquisition device 2. The anti-slip device 3 is wrapped around the end of the lens of the acquisition device 2 and fixed. Specifically, waterproof tape can be used for fixing. The anti-slip device 3 is made of rubber. The fixing component 5, the anti-slip device 3 and the acquisition device 2 cooperate with each other to prevent the fixing component 5 from falling off the acquisition device 2 and avoid damage to the acquisition device 2.

[0032] Specifically, the adjusting base has a through hole, and the adjusting member 6 passes through the through hole. The adjusting member 6 is clearance-fitted with the adjusting base, or a groove is opened on the adjusting base, and the adjusting member 6 is placed in the groove so that the adjusting member 6 fits into the groove. When the relative position of the two ends of the adjusting member 6 is adjusted, the adjusting base drives the relative positional relationship between the inner side wall of the fixing member 5 and the outer side wall of the collecting device 2, that is, adjusts the mutual cooperation relationship between the fixing member 5 and the collecting device 2. When the two ends of the adjusting member 6 are adjusted to reduce the area enclosed by the adjusting member 6, the inner side wall of the fixing member 5 can be tightly fitted with the outer side wall of the collecting device 2, thereby firmly fixing the guide mechanism 1 to the collecting device 2. When the two ends of the adjusting member 6 are adjusted to increase the area enclosed by the adjusting member 6, the inner side wall of the fixing member 5 can be moved away from the outer side wall of the collecting device 2, thereby removing the guide mechanism 1 from the collecting device 2.

[0033] The working principle of this utility model:

[0034] During the signal acquisition process inside the goaf exploration borehole, when the acquisition device 2 is unable to enter the goaf smoothly due to borehole wall deformation, the acquisition device 2 is lifted to the ground. After the acquisition device 2 is placed on a stable table, the anti-slip device 3 is wrapped and fixed to the lens end of the acquisition device 2. Then, the fixing part 5 on the guide mechanism 1 is attached to the anti-slip device 3. The relative positions of the two ends of the adjusting part 6 are adjusted. The adjusting part 6, the adjusting base and the fixing part 5 cooperate with each other to firmly fix the guide mechanism 1 to the acquisition device 2, so that the video acquisition can continue inside the goaf exploration borehole.

[0035] Regarding the specific structure of this utility model, it should be noted that the connection relationships between the various components and modules adopted in this utility model are definite and achievable. Except as specifically described in the embodiments, the specific connection relationships can bring about corresponding technical effects and solve the technical problems proposed by this utility model without relying on the execution of corresponding software programs.
