Detailed Description

The present application is described in further detail below with reference to figures 1-4.

The embodiment of the application discloses prevent interior restoration pipe of jam.

Referring to fig. 1, an anti-clogging inner repair pipe comprises a repair hose 1, wherein a plurality of supporting pieces 2 are arranged on the inner side wall of the repair hose 1, and the supporting pieces 2 are used for supporting the repair hose 1 on a pipeline. The support pieces 2 are transversely arranged and vertically arranged, and the support pieces 2 transversely arranged correspond to the support rods vertically arranged one to one. The corresponding two supports 2 are crosswise so that the repair hose 1 is abutted inside the pipe. The support member 2 includes a connecting rod 22 and two limiting blocks 21, and the connecting rod 22 is a telescopic rod.

In practice, the length of the connecting rod 22 is adjusted according to different sizes of pipes, and the support member 2 is held against the repair hose 1 so that the outer side wall of the repair hose 1 is fitted to the inner side wall of the pipe, thereby fixing the repair hose 1. The supporting strength of the repairing hose 1 is increased by the supporting piece 2, and secondary damage of the repaired pipeline is not easy to happen.

Referring to fig. 2 and 3, the connecting rod 22 is composed of a threaded sleeve 222 and two threaded rods 221, and the two threaded rods 221 are respectively inserted into two ends of the threaded sleeve 222. The limiting block 21 is provided with a limiting groove 3, one end of the threaded rod 221 penetrating into the threaded sleeve rod 222 is in threaded connection with the threaded sleeve rod 222, and the other end penetrates into the limiting groove 3. In practice, after the repair hose 1 is fixed in the pipe, the threaded rod 221 is inserted into the limit groove 3 and the threaded rod 221 is rotated so that both threaded rods 221 abut against the inner side wall of the repair hose 1.

Referring to fig. 1 and 3, a plurality of limiting pieces 4 are arranged on the limiting block 21, and the limiting pieces 4 are arranged along the circumferential direction of the limiting groove 3 and are arranged at the outer edge of the limiting groove 3. When the threaded rod 221 is inserted into the limiting groove 3, the limiting sheet 4 at the outer edge of the limiting groove 3 wraps the threaded rod 221. The limiting block 21 is provided with a threaded ring 5, the limiting sheet 4 is abutted to the threaded rod 221 by rotating the threaded ring 5, so that the position of the threaded rod 221 cannot deviate, the stability is improved, and the connecting rod 22 always keeps supporting the repair hose 1.

Referring to fig. 1, two limiting blocks 21 on the same support member 2 are all fixed and arranged on the inner side wall of the repair hose 1 and at two ends of the inner diameter of the repair hose 1, so that the connecting rod 22 is located on the inner diameter of the repair hose 1, the repair hose 1 can be supported to the greatest extent, and the stress of the repair hose 1 at the same position is prevented from being uneven. The stopper 21 is a hard block, so that the position of the connecting rod 22 is stabilized. The distance between two horizontal adjacent stopper 21 is 5cm to 7cm to ensure that the interval between connecting rod 22 is shorter, can support repair hose 1 more closely, improve stability. Be equipped with thickening layer 6 and thickening layer 6 along the outer edge setting of stopper 21 and with stopper 21 fixed connection on the inside wall of restoreing hose 1. The thickness of thickening layer 6 is towards keeping away from stopper 21 direction attenuation gradually to make connecting rod 22 certain buffer power when the atress, thickening layer 6 has dispersed the pressure that comes from the ground, has improved the compressive strength of pipeline, make the pipeline be difficult to take place the secondary damage.

Referring to fig. 1, both ends of the repair hose 1 are provided with buffer blocks 7, and the buffer blocks 7 are annularly fixed at the end of the repair hose 1. One end of the buffer block 7 close to the repair hose 1 is flush with the inner side wall of the repair hose 1, and one end of the buffer block 7 far away from the repair hose 1 is flush with the outer side wall of the repair hose 1. The arrangement of the buffer block 7 reduces the resistance of the medium in the pipe when the medium enters the repair hose 1, so that the medium flows more smoothly, and the adhesion reduction caused by the fact that the medium washes the end part of the repair hose 1 for a long time is prevented.

Referring to fig. 1 and 4, a supporting hose 8 is arranged in the repairing hose 1, a notch 9 is arranged on the outer side wall of the supporting hose 8, the notch 9 corresponds to a protrusion on the inner side wall of the repairing hose 1, when the supporting hose 8 is arranged inside the repairing hose 1, the protrusion on the inner side wall of the repairing hose 1 is clamped and embedded in the notch 9 of the supporting hose 8, and the inner side wall of the supporting hose 8 is a flat surface. Need use the gasbag to glue the restoration hose 1 that scribbles epoxy on the pipeline inside wall when carrying out the restoration operation, consequently the use of gasbag can be ensured in the setting of support hose 8 for restoration hose 1 can glue on the pipeline inside wall.

The implementation principle of the anti-blocking internal repair pipe in the embodiment of the application is as follows: the air bag is placed in the supporting hose 8 and inflated, the supporting hose 8 drives the repairing hose 1 to expand, and the repairing hose 1 is connected with the pipeline through epoxy resin. The support hose 8 is taken out after the repair hose 1 and the pipeline are bonded, the threaded rod 221 is inserted into the limiting groove 3, the threaded rods 221 at the two ends of the threaded sleeve rod 222 are all abutted to the repair hose 1 by rotating the threaded rod 221, so that the repair hose 1 is further fixed on the inner side wall of the pipeline, and the stability of the repair hose 1 is improved.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
