Further: the protective sleeve is lifted in the drill hole through lifting equipment, the lifting equipment comprises a tripod support and a lifting rope, one end of the lifting rope is connected with the joint, and the end far away from the joint is connected with the winch.

Further: the material of half-closed pipe is PVC material.

Further: the semi-closed pipe is arranged in a semicircular mode, and the outer diameter of the circular pipe is smaller than the inner diameter of the drilled hole.

Compared with the prior art, the utility model discloses following beneficial effect has:

the utility model discloses can effectively protect downthehole TV probe, prevent that the probe from destroying or losing, when taking place to fall the piece or the hole accident that collapses, PVC protective case probably can't take out, nevertheless for traditional method, probe equipment and cable receive the protection, and the loss is less. The utility model discloses the raw and other materials of half-closed pipe easily gain, and processing is convenient, and the relative probe equipment of cost and cable are cheap.

Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

As shown in fig. 1-3, the utility model provides a protective sleeve structure for in-hole television imaging, which comprises a probe 8, a cable 5 and an in-hole television host 6, wherein the probe 8 is connected with the in-hole television host 6 through the cable 5, the cable 5 is provided with a protective sleeve section which is formed by splicing a plurality of groups of protective sleeves, the length of each group of protective sleeves is basically consistent, the protective sleeve comprises a circular tube formed by splicing two half tubes 2, the two ends of the circular tube are provided with connectors 3, the end parts of the half tubes 2 and the insides of the connectors 3 are respectively provided with a clamping groove and a clamping tooth which can be tightly combined, two adjacent circular tubes are connected through the connectors 3, the test drilling hole opening is provided with a circular caliper 4, the circular caliper 4 is formed by two semi-ring hoops, the two ends of the semi-ring are outwards bent to form installation ears, the two semi-ring hoops are connected through the installation ears, the size of the round opening caliper 4 is close to the same as the outer diameter of the spliced round pipe, and is smaller than the outer diameter of the connector 3, when the protective sleeve is suspended and fixed in the orifice, only the mounting lug on one side of the round opening caliper 4 needs to be detached, one of the semi-ring hoops is opened in a rotating mode, the spliced round pipe below the connector 3 is fixed on the round opening, and the mounting lug of the round opening caliper 4 is mounted. The round calipers 4 are used as a joint 3 for connecting two adjacent protective sleeves to suspend and fix the tool.

The protective sleeve is lifted in the drill hole through lifting equipment, the cable and the probe are lowered and lifted through manpower or a winch, the lifting equipment comprises a tripod support 1 and a lifting rope 7, one end of the lifting rope 7 is connected with the joint 3, and one end, far away from the joint 3, of the lifting rope is connected with the winch or operated through manpower.

The semi-closed pipe 2 is made of PVC. The half-closed pipe 2 and the joint 3 can be reused. The PVC protection sleeve can be with downthehole TV cable 5 inclusion in the pipe, when taking place downthehole accident, when carrying out the process that promotes to protection cable 5 and probe 8, prevents that it from falling the piece and destroying by the pore wall.

The semi-closed pipe 2 is arranged in a semicircular mode, and the outer diameter of the circular pipe is smaller than the inner diameter of a drilled hole.

The working steps of the protective sleeve structure are as follows:

firstly, roughly estimating and determining the length of a protective sleeve according to the hole depth, correspondingly penetrating a plurality of joints 3 on a cable 5, installing two half-closed pipes 2 at the first joint 3 close to a probe 8, and placing the cable 5 in a circular pipe formed by splicing the half-closed pipes 2; a lifting rope 7 is arranged on the tripod bracket 1, and the lifting rope 7 is connected with one side of the combined joint 3 through a top roller of the tripod bracket 1; the circular pipe that will splice the completion is lifted by crane and is transferred to the drilling, simultaneously the manual work transfers cable 5 and probe 8 together to utilize circular mouthful calliper 4 to be fixed in experimental drilling drill way mouth with the joint 3 that the circular pipe is connected. After the round calipers 4 fix the joints 3, the lifting ropes 7 are detached from the joints 3 and are installed with the next joint 3, and the next section of round pipe is continuously spliced; after the next section of circular pipe is spliced, the tripod support 1 is used for lifting and lowering, and the other end of the tripod support is fixedly butted with the joint 3 fixed on the orifice. The actions are repeated, so that the protective sleeve structure is synchronously spliced and extended to the maximum test depth in the process of lowering the probe 8.

After the detection is finished, in the lifting process of the probe 8, the protective sleeve structure is synchronously lifted, and when one section of protective sleeve is completely positioned above the hole opening, the section of protective sleeve is disassembled until the probe 8 is completely lifted out of the test drilling hole opening.

When an accident occurs in the hole and the protective sleeve cannot be lifted, the cable 5 and the probe 8 are directly lifted, and the test probe 8 in the hole is taken out.

The above embodiments are merely preferred technical solutions of the present invention, and it should be understood by those skilled in the art that modifications or substitutions of technical solutions or parameters in the embodiments can be made without departing from the principles and essential conditions of the present invention, and all the modifications or substitutions should be covered within the protection scope of the present invention.
