[0002] The borehole hole camera technology can collect the most intuitive image and video data of the borehole wall, measure and analyze the position, width and rock mass structure surface occurrence data of the borehole fracture and broken zone, and effectively make up for the shortcomings of coring drilling.

[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the present application.

[0027] Reference Figs. 1 to 3 The embodiment of the present application provides a sewage replacement device in a drill hole, which can solve the problems of low washing quality and efficiency, and influence the efficiency and effect of camera shooting in the drill hole.

[0028] The embodiment of the present application provides a sewage replacement device in a drill hole, which comprises a water storage part 1, a counterweight 3 and a drainage assembly 4, the water storage part 1 is made of transparent soft film material, a water storage cavity 10 is formed in the water storage part 1, one end of the water storage cavity 10 is open, and the other end is sealed; the counterweight 3 is connected with the water storage part 1; the drainage assembly 4 is connected with the water storage part 1, and a drainage port is formed on the water storage part 1 when the drainage assembly 4 moves relative to the water storage part 1.

[0029] In the present application, when the water storage part 1 is in the first state, the water storage part 1 is folded and compressed into a roll, the volume after compression is small, and the transportation is convenient and fast; the size of the water storage part 1 can be selected according to different hole diameters and hole depths; the water storage part 1 is made of transparent soft film, has the characteristics of transparency, easy compression, good adhesion, sufficient elasticity and the like, is easy to fold and compress to reduce the buoyancy when put into the drill hole, can easily sink to the bottom under the traction of the counterweight 3, injects water into the inside of the water storage cavity 10, expands and unfolds from the bottom, extrudes the sewage in the drill hole from the bottom to the top, and places the camera shooting equipment in the water storage cavity 10, so that the water storage part 1 has a certain protection for the camera shooting equipment in the drill hole, and reduces the risk of burying the camera by the falling debris of the hole wall; the drainage assembly 4 is arranged, a drainage port is formed on the water storage part 1 when the drainage assembly 4 moves relative to the water storage part 1, the clean water in the water storage cavity 10 flows out, and the sewage replacement device can be recycled.

[0030] When the transparent PET soft film is unfolded, it is in a rectangular structure, the two sides are connected to form a cylindrical structure, and then the soft film at one end of the cylindrical structure is folded and compressed along the diameter to be closed to form the water storage part 1. Because the water storage part 1 is made of transparent PET soft film material, it has the characteristics of softness, good adhesion, sufficient elasticity and the like, so the water storage part 1 can be folded and compressed during transportation; and the length can be selected according to different hole depths during use, and is suitable for drill holes of various depths, and different soft film sizes can be configured according to different hole diameters, and is suitable for drill holes of various hole diameters. When the water storage part 1 is put into the drill hole, it is easy to fold and compress to reduce the buoyancy, can easily sink to the bottom under the traction of the counterweight 3, injects water into the inside of the water storage cavity 10 after unfolding, and places the camera shooting equipment, so as to protect the camera shooting equipment in the drill hole and reduce the risk of burying the camera by the falling debris of the hole wall.

[0031] On the basis of the above embodiment, in the present embodiment, the water storage part 1 is connected with a water injection structure 2, one end of the water injection structure 2 is a water inlet, and the other end is a water outlet, and the water injection structure 2 is used for injecting water into the inside of the water storage cavity 10.

[0032] In this embodiment, clean water is injected into the water storage chamber 10 through the water injection structure 2. The water storage chamber 10 stores clear water to form an independent water chamber, which can effectively maintain the hole washing effect and prevent turbid and polluted groundwater from entering the borehole. The camera equipment inside the borehole can clearly capture images of the situation inside the borehole from inside the water storage chamber 10. During the water injection process, the folded and compressed water storage component 1 gradually expands, and the diameter of the water storage chamber 10 expands to be slightly smaller than the borehole diameter, gradually squeezing the sewage out of the borehole.

[0033] In some possible embodiments, the water injection structure 2 is a water injection membrane 20, which is connected to the water storage component 1 and forms a water injection corridor 200 between the water injection membrane 20 and the water storage component 1. One end of the water injection corridor 200 is provided with a water inlet, and the other end is provided with a water outlet, which is connected to the interior of the water storage cavity 10.

[0034] In this embodiment, the water injection membrane 20 can be configured in various ways, for example, as follows: Fig. 3 As shown, the water injection membrane 20 is disposed inside the water storage cavity 10: the water injection corridor 200 is open at both ends, with one end being a water inlet and the other end being a water outlet. The water injection corridor 200 is located inside the water storage cavity 10, and there is a gap between the water outlet and the bottom of the inner wall of the water storage cavity 10. Clean water flows into the bottom of the water storage cavity 10 through the water injection corridor 200, which can expel the gas inside the water storage cavity 10.

[0035] Alternatively, the water injection membrane 20 is disposed outside the water storage cavity 10: the water injection corridor 200 is open at one end and sealed at the other end, with the open end serving as the water inlet. A through hole is provided on the water storage component 1. The water injection corridor 200 is located outside the water storage cavity 10, and the through hole is located inside the water injection corridor 200, forming the water outlet of the water injection corridor 200. The through hole is located on the water storage component 1 near the bottom of the water storage cavity 10, allowing clean water to pass through the water injection corridor 200 and then through the water outlet into the interior of the water storage cavity 10.

[0036] In this embodiment, both ends of the water injection membrane 20 are connected to the water storage component 1.

[0037] In this embodiment, the drainage component 4 can also be configured in several ways:

[0038] For example, the drainage assembly 4 comprises a cutting rope 40, which is arranged through the water storage member 1 and has one end inside the water storage cavity 10 and the other end outside the water storage cavity 10. When the cutting rope 40 moves on the water storage member 1, a drainage opening is formed on the water storage member 1. The cutting rope is arranged to pass through the bottom of the water storage cavity 10 and has a sufficient length to be pulled out of the borehole. After the in-hole test is completed, the cutting rope 40 is pulled up to cut the water storage member 1, so that a drainage opening is formed on the water storage member 1, and the clean water in the water storage cavity 10 flows out, thereby quickly recovering the sewage displacement device. When the water injection film 20 is arranged inside the water storage cavity 10, one end of the cutting rope 40 is arranged inside the water injection corridor 200, and the other end is arranged outside the water storage cavity 10, so that the cutting rope 40 does not contact the in-hole test equipment, and the cutting rope 40 is prevented from being entangled with the equipment.

[0039] For another example, the drainage assembly 4 comprises a cutting member and a connecting rope, one end of the cutting member is arranged inside the water storage cavity 10, and the other end is arranged outside the water storage cavity 10. The two ends of the cutting member are connected with the connecting rope. The cutting member is made of metal or ceramic, and compared with the cutting rope 40 cutting the water storage member 1, the cutting member is more labor-saving. Further, the cutting member is provided with cutting sawteeth at the end close to the opening of the water storage cavity 10. The connecting rope is pulled out of the borehole. After the in-hole test is completed, the connecting rope is pulled up to make the cutting member cut the water storage member 1, so that a drainage opening is formed on the water storage member 1, and the clean water in the water storage cavity 10 flows out, thereby quickly recovering the sewage displacement device. When the water injection film 20 is arranged inside the water storage cavity 10, one end of the connecting rope is arranged inside the water injection corridor 200, and the other end is arranged outside the water storage cavity 10, so that the connecting rope does not contact the in-hole test equipment, and the connecting rope is prevented from being entangled with the equipment.

[0040] For another example, the drainage assembly 4 comprises a film and a connecting rope, and the water storage member 1 is provided with an aperture. The film is bonded to the water storage member 1 and covers the aperture. The connecting rope is connected with the film. The aperture can be formed on the water storage member 1 after the water storage member 1 is formed, or when the water storage member 1 is made of transparent PET soft film, the two sides of the transparent PET soft film are connected to form a cylindrical structure by the film, and the two sides of the transparent PET soft film are not connected to form the aperture. When the film is separated from the water storage member 1, the aperture is a drainage opening. The connecting rope is arranged outside the water storage cavity 10 and connected with the bottom end of the film at one end and pulled out of the borehole at the other end. When the connecting rope is pulled up, the film can be separated from the water storage member 1.

[0041] In some possible embodiments, the water injection structure 2 is provided as a water injection hose made of soft film material. The water injection hose has openings at both ends, and the water storage member 1 is provided with a through hole. The water injection hose is arranged outside the water storage cavity 10, and one end of the water injection hose is bonded to the water storage member 1 and communicates with the through hole.

[0042] The one end of the water injection hose is bonded to the water storage part 1, and the bonding material is waterproof glue, and the water injection hose is made of soft film material. The through hole in the embodiment is also provided on the water storage part 1 near the bottom of the water storage cavity 10, so that the clean water passes through the water injection hose and then passes through the through hole into the inside of the water storage cavity 10.

[0043] The other end of the water injection hose is pulled out of the hole, and after the camera test in the hole is completed, the other end of the water injection hose is pulled to separate the water injection hose from the water storage part 1. When the water injection hose is separated from the water storage part 1, the through hole is a water outlet, so that the clean water in the water storage cavity 10 flows out, and the sewage replacement device can be quickly recovered.

[0044] The above embodiment is only one of the possible implementations of the present application, and the present application is not limited thereto.

[0045] The use steps of the device are as follows:

[0046] After the hole washing and standing are completed, a water storage part 1 with sufficient length according to the drilling depth is prepared, the water storage part 1 is compressed by folding multiple times, and the one end of the water storage part 1 is connected with the counterweight 3 and then put into the hole.

[0047] After the one end of the water storage part 1 sinks to the bottom of the hole, water is injected from the water inlet of the water injection structure 2. As the water storage cavity 10 gradually stores water and expands, the sewage gradually flows out from the gap between the water storage part 1 and the hole wall.

[0048] After the water injection is completed to the appropriate position, the camera test equipment in the hole is put into the hole from the water storage cavity 10 for shooting.

[0049] After the camera test equipment in the hole is recovered, the water drainage assembly 4 is moved upward to form a water outlet on the water storage part 1, and then the water storage part 1 is gradually lifted to recover the sewage replacement device.

[0050] In summary, the sewage replacement device has the following advantages:

[0051] The sewage replacement device can be compressed into a roll, and after being compressed into a roll, it occupies a small volume and is convenient and fast to carry. When used, the length can be selected according to different hole depths, and it is suitable for holes with various depths.

[0052] The water storage part 1 can be configured with different sizes according to different hole diameters, and it is suitable for holes with various diameters.

[0053] The water storage part 1 is made of PET soft film, which has the characteristics of transparency, easy compression, good adhesion, sufficient elasticity, etc. When put into the hole, it is easy to fold and compress to reduce the buoyancy, and the one end of the water storage part 1 can easily sink to the bottom under the traction of the counterweight 3. After water injection and expansion, the camera equipment in the hole has a certain protection, which reduces the risk of hole wall debris burying the camera.

[0054] The water storage part 1 is made of transparent material, clear water is stored in the water storage cavity 10 to form an independent water chamber, which can effectively maintain the hole washing effect, prevent underground turbid contaminated water from entering the hole, and the camera equipment in the hole can clearly shoot the situation in the hole in the water storage cavity 10.

[0055] The drainage assembly 4 is connected with the water storage part 1, and after the hole camera test is completed, the drainage assembly 4 is moved on the water storage part 1 to form a drainage port, so that the clear water in the water storage cavity 10 flows out, and the device can be quickly recovered.

[0056] The application has the advantages of reasonable design, simple structure, convenient use, high working efficiency, good replacement effect and environmental protection, and is suitable for replacement of drilling sewage of various diameters.
