Detailed Description

The utility model is described in more detail below with reference to the drawings accompanying the specification.

The utility model provides a supporting structure of an in-pipeline detector, which is used for better providing supporting force for the in-pipeline detector in all directions and has better structural stability, so that smooth operation of detection is ensured.

As shown in fig. 1-2, an in-pipeline detector supporting structure is an integrated structure formed by a round bottom disc 1 and a plurality of claw structures 2, and the supporting function of the in-pipeline detector is realized together. The center of the round bottom disk 1 of the supporting structure is provided with a circular hole 3, and the circular hole 3 enables the detector in the pipeline to pass through. The outer circumference of the supporting structure is uniformly cut into a plurality of claw-shaped structures 2, a plurality of V-shaped empty slots 5 are formed between the adjacent claw-shaped structures 2, one side of the round base plate 1, which is provided with claw ends 21 along the radial direction, is obliquely arranged in an inner buckling manner, and the claw ends 21 of the plurality of claw-shaped structures 2 are obliquely arranged in an expanding manner along the radial direction of the round base plate 1; the inner surface of the round chassis 1 is fixedly connected with a detector in the pipeline.

The round bottom plate 1 and the claw-shaped structures 2 are made of polyurethane, the round bottom plate 1 is a disc-type polyurethane thin plate structure, the claw-shaped structures 2 are L-shaped thin plates made of polyurethane and provided with circular arcs, the round bottom plate 1 is arranged in an inner buckling type inclined mode, and claw ends 21 of the claw-shaped structures 2 are arranged in an expanding type inclined mode and can adapt to pipe diameter changes. The circular base plate 1 and the claw-shaped structures 2 jointly provide tension support, and the size of the diameter dimension of the circular base plate 1 and the claw-shaped structures 2 when in contact with the inner wall of the pipe can be adaptively adjusted according to the size of the inner diameter of the pipe, so that the circular base plate can adapt to different inner diameters of the pipe. Therefore, the support structure of the detector in the pipeline can adapt to the pipe diameter change, has good support capacity, and can adapt to the detector in the small-caliber pipeline.

Compared with the traditional leather cup, the structure design is better in adaptation to pipe diameter change, has better stability, reduces the contact area between the supporting structure and the inner wall of the pipe by the claw-shaped structure 2, and can effectively reduce friction force. The detector can be suitable for the detector in the small-caliber pipeline. And the plurality of V-shaped empty slots 5 between the plurality of claw structures 2 can reduce the influence of gas and liquid on the supporting structure through the gas and the liquid.

Around the round hole 3, 12 screw holes 4 are surrounded, and the supporting structure round chassis 1 is fixedly connected with the screw of the detector in the pipeline through the screw holes 4. Along with the radial slope setting that is interior knot formula along the one side that is provided with claw end 21 of circle chassis 1, through the connection of screw 4, make this bearing structure and pipeline inner detector laminating be connected, the steadiness is better.

The outer circumference of the supporting structure is evenly cut into 6 claw-shaped structures 2, and 6V-shaped empty grooves 5 are formed between every two adjacent claw-shaped structures 2. The included angle between the V-shaped empty grooves 5 is within 30-60 degrees, the larger the included angle is, namely the larger the opening is, the smaller the friction force is, but the supporting force is reduced. The specific numerical value is set according to actual needs, and the included angle between the V-shaped empty slots 5 is set to be 30 degrees in the embodiment, which is equivalent to equally dividing a circle into 12 parts along the circumferential direction, wherein the arc length of the claw-shaped structures 2 is equidistant from the arc length of the V-shaped empty slots 5, and the claw-shaped structures are arranged at intervals, so that the friction force is reduced to the greatest extent while the supporting force is ensured by the 6 claw-shaped structures 2.

The circular hole 3 has a diameter equal to or slightly larger than the outer diameter of the detector body for the purpose of securely mounting it to the detector body.

The tip of the V-shaped empty groove 5 is arc-shaped, so that arc transition of a sharp corner part is realized, stress concentration at the position is reduced, and the empty groove is prevented from being stressed and damaged.

The concrete installation mode is as follows: the side of the in-pipe detector supporting structure provided with the claw end 21 faces the in-pipe detector, and the side not provided with the claw end 21 is the advancing direction of the in-pipe detector.
