When the internal connection device is installed, the sealing member 201 and the reinforcing member 202 are used to seal the external connection of the pipes. In the device, the fastening piece 103 can also prevent the tensioning piece 102 from loosening by using the fluid in the pipeline, and the pipeline can be prevented from leaking and falling off.

Example 2

Referring to fig. 2 to 9, a second embodiment of the present invention is based on the above embodiment.

Specifically, the supporting member 101 includes a supporting tube 101a disposed in the pipeline, and supporting frames 101b disposed at two ends of the supporting tube 101a, wherein the supporting frames 101b are fixedly connected to ends of the supporting tube 101 a. In this embodiment, the support frame 101b is provided with four arms, integrally formed with the support tube 101a, in order to reduce the influence of the device on the water flow.

Preferably, the outer surface of the support tube 101a is further provided with at least one limiting groove 101a-1, and the limiting groove 101a-1 is in a long strip shape. In this embodiment, four limiting grooves 101a-1 are provided, and the middle part of the limiting groove 101a-1 is wider, and two ends of the limiting groove are narrower, so that the movement of the tensioning arm 102c is facilitated, and the movement of the mounting box 103a is also facilitated.

Preferably, the tension member 102 comprises a screw rod 102a disposed in the middle of the support tube 101a, and a moving ring 102b disposed on the screw rod 102a, wherein both ends of the screw rod 102a are rotatably engaged with the middle of the support frame 101b, and the moving ring 102b is threadedly engaged with the screw rod 102 a. The moving rings 102b are provided in two, and the thread directions inside the two moving rings 102b are opposite, so that when the screw rod 102a rotates, the two moving rings 102b move towards each other, and a hinge support is correspondingly installed on each moving ring 102 b.

Preferably, the tensioning member 102 further comprises a tensioning arm 102c disposed in the limiting groove 101a-1, and a tensioning block 102d hinged to an end of the tensioning arm 102c, wherein the other end of the tensioning arm 102c is hinged to the moving ring 102b, the tensioning arm 102c is further provided with an overflowing hole 102c-1, and a surface of the tensioning block 102d is further provided with a first protrusion 102d-1. In the present embodiment, four pairs of tensioning arms 102c are provided, and when the moving rings 102b move towards each other, i.e. the distance between the moving rings 102b gradually decreases, the tensioning arms 102c expand outwards accordingly until the tensioning blocks 102d are pressed against the inner wall of the pipe, and the surface shape of the tensioning blocks 102d is arc-shaped and is attached to the inner wall of the pipe. The overflow aperture 102c-1 in tensioner arm 102c is to reduce the obstruction of fluid in the conduit by tensioner arm 102 c. The first protrusion 102d-1 is for positioning when the pipes are butted.

Preferably, the fastening device 103 includes a mounting box 103a disposed on one side of the tensioning block 102d, and an impeller 103b disposed inside the mounting box 103a, a shaft of the impeller 103b is rotatably engaged with the mounting box 103a, a shaft of the other end of the impeller 103b is provided with a screw thread and is threadedly engaged with the tensioning block 102d, and the mounting box 103a is provided with a water inlet 103a-1. When fluid flows in the pipeline, the fluid can impact the impeller 103b while flowing through the mounting box 103a through the water inlet 103a-1, the impeller 103b is forced to rotate, and the shaft at the end of the impeller 103b is in threaded fit with the tensioning block 102d, so that the impeller 103b can move axially while rotating.

Preferably, the fastening member 103 includes a fastening block 103c disposed in the tensioning block 102d, a surface of the fastening block 103c is provided with a second protrusion 103c-1, and the fastening block 103c is rotatably engaged with a shaft of the impeller 103b and slidably engaged with the tensioning block 102 d. When the impeller 103b is rotated, the end of its shaft moves outwardly against the fastening block 103c, thereby further tightening the tube wall.

Preferably, the fastening device 103 further comprises at least one water rotating wheel 103d disposed inside the screw rod 102a, at least one operation hole 103e disposed in the middle of the screw rod 102a, and an operation rod 103f engaged with the operation hole 103e, and an operation block 103f-1 is further disposed at an end of the operation rod 103 f. Similarly, when fluid impacts the water runner 103d inside the screw rod 102a, the water runner 103d tends to rotate, and it should be noted that, blades of the water runner 103d are fixedly connected with an inner wall of the screw rod 102a, and the blades are arranged at an angle to ensure that the blades rotate when being impacted by the front surface of water flow, so that when the water runner 103d tends to rotate, the screw rod 102a tends to rotate, and when the screw rod 102a is impacted by the water flow, the screw rod 102a can be prevented from rotating, thereby causing the tensioning block 102d to be loose. Due to the existence of the first protrusion 102d-1 and the second protrusion 103c-1, a gap exists at the joint of the two pipes, the operating rod 103f is inserted into the operating hole 103e from the gap, and then rotated, pulled out, and then inserted again for rotation, and the reciprocating operation is performed, so that the screw rod 102a can be screwed outside the pipes. At the same time, the operation block 103f-1 is left outside the pipe, and the pipe port can be used to prevent the device from moving integrally along the axial direction of the pipe.

Further, the sealing member 201 includes at least one layer of sealing collar 201a disposed outside the pipe, and a through hole 201b is further disposed on a surface of the sealing collar 201 a. The sealing collar 201a is made of rubber materials, has different sizes, and can be added on the outer wall of the pipeline in a circle. The through hole 201b is provided to facilitate the extension of the operation block 103f-1.

Further, the reinforcing member 202 includes a hoop 202a disposed outside the sealing collar 201a, the end portions and the middle portion of the hoop 202a are respectively provided with a connecting block 202b, and the hoops 202a are connected by bolts. The band 202a is divided into a total of four parts, which are reinforced both radially and axially.

In use, the fixing assembly 100 is first placed entirely into one of the pipes to be connected, and then the screw 102a is rotated by using a wrench or other suitable tool to gradually draw the two moving rings 102b together, and at the same time, the tensioning arm 102c begins to gradually expand outward, and when the tensioning block 102d at the end of the tensioning arm 102c touches the inner wall of the pipe, the preliminary installation is completed. Then, another length of pipe to be connected is butted up to the side edges of the first projection 102d-1 and the second projection 103 c-1. Then the operating rod 103f is inserted into the operating hole 103e in the middle of the screw rod 102a from the gap at the joint of the pipelines, the operating block 103f-1 is shifted to rotate, then the operating rod 103f is pulled out to return to the original position for reinsertion, and then the operation is repeated until the screw rod 102a can not rotate any more, namely the tensioning block 102d completely pushes up the inner walls of the two pipelines. At this time, another operation rod 103f can be inserted, so that the whole device can be prevented from moving axially.

After the installation is completed, the sealing collar 201a can be installed from the outside, multiple layers can be installed according to the diameter size and the application of the pipeline, then the hoop 202a is fastened on the sealing collar 201a, and the four hoops 202a are connected and fixed in the radial direction and the axial direction through bolts.
