Description

Technical Field

[0001] This utility model relates to a connection and sealing device, and more particularly to a connection and sealing device for the inner wall of a pipe. Background Technology

[0002] Water conservancy projects are engineering projects constructed to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. Water conservancy projects require the construction of different types of hydraulic structures such as dams, dikes, spillways, sluice gates, intakes, canals, ferries, raft channels, and fishways, and the laying of water conservancy pipelines to achieve their purpose. When laying water conservancy pipelines, it is necessary to use pipe inner wall connection and sealing devices.

[0003] For example, Chinese Patent Publication No. CN221800916U discloses a water conservancy engineering pipeline inner wall connection sealing device, which relates to the field of water conservancy engineering technology. It includes a pipeline A and a flange B. The upper end of the pipeline A is fixed with flange A, and a round-headed positioning post is fixed above the outer surface of flange A. The inner surface of the round-headed positioning post is provided with an installation assembly for installation and fixing. The installation assembly includes a connecting pin, a torsion spring, and a pin claw. Torsion springs are provided on both sides of the connecting pin. Compared with existing ordinary pipeline inner wall connection sealing devices, this water conservancy engineering pipeline inner wall connection sealing device allows the round-headed positioning post on flange A to be inserted into the empty space of flange B. The round-headed positioning post can provide positioning and quick installation. Then, the connecting pin is inserted into the hole of the round-headed positioning post. After the connecting pin is fully inserted, the pin claw is opened by the elastic force of the torsion spring and engages in the groove of the round-headed positioning post, completing the installation. This allows the inner wall connection sealing device to be installed and connected quickly. Some problems have been found when using the existing water conservancy project pipeline inner wall connection sealing device. First, the alignment requirements of the connected pipelines are too high. Often, when two pipelines are installed in sections, due to worker operation errors and limitations of on-site construction technology, it is difficult to accurately align the two pipelines. As a result, the device cannot connect and install the pipelines due to misalignment of the two pipeline ports. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4This utility model provides a technical solution: a pipe inner wall connection sealing device, including a connecting hose 2 and a pipe 9. Both ends of the connecting hose 2 are fixedly connected with connecting cones 1. The connecting cones 1 have a connection port 101 inside, which communicates with the inside of the connecting hose 2. The end of the connecting cones 1 is inserted into the pipe 9. A telescopic rod is provided between the two connecting cones 1.

[0016] In this implementation scheme, the pipe 9 is pre-installed and fixed by a pipe rack to fix its position. Then, two connecting cones 1 are inserted into the ports of the pipe 9 respectively. The connecting hose 2 is connected to the inside of the connection port 101, and the two connecting cones 1 can be connected through the connecting hose 2. Then, the length of the telescopic rod is adjusted, and the connecting cones 1 are pushed by the telescopic rod to squeeze the connecting cones 1 to the port of the pipe 9, so that the connecting cones 1 and the end edge of the pipe 9 are tightly fitted together, and the connecting cones 1 and the pipe 9 are sealed together. The connecting hose 2 is made of flexible material and can be bent at any angle. Even if the ports of the two pipes 9 are misaligned, the inner walls of the two connecting cones 1 can be sealed together.

[0017] To achieve the purpose of adjusting the length of the telescopic rod, the device adopts the following technical solution: a sealing gasket 102 is fixedly connected to the outer wall of the connecting cone 1; the telescopic rod includes a connecting threaded sleeve 5 and two threaded posts 4; the two threaded posts 4 are threadedly installed at both ends of the connecting threaded sleeve 5; several spherical mounting seats 3 are fixedly connected in an orderly manner to the adjacent surfaces of the two connecting cones 1; a ball head 401 is fixedly connected to the end of the threaded post 4; the ball head 401 is rotatably installed in the spherical mounting seat 3; a first nut 402 is fixedly connected to the threaded post 4; and a second knob 501 is fixedly connected to the middle of the connecting threaded sleeve 5.

[0018] The sealing gasket 102 is fixed to the outer wall of the connecting cone 1, and the sealing gasket 102 is located at the gap between the end edge of the pipe 9 and the outer wall of the connecting cone 1. The sealing gasket 102 can seal the gap between the pipe 9 and the connecting cone 1. The ball head 401 is rotatably installed inside the spherical mounting seat 3, and the telescopic rod can be rotatably installed between the two connecting cones 1, so that the two connecting cones 1 are in a misaligned state, and the telescopic rod is kept connected to the two connecting cones 1. The first nut 402 and the second knob 501 can be used in conjunction with a wrench to manually rotate the connecting threaded sleeve 5, which can drive the two threaded posts 4 to move. The movement of the threaded posts 4 can in turn drive the connecting cone 1 to move, and the connecting cone 1 can be squeezed into the port of the pipe 9.

[0019] The working principle and usage process of this utility model are as follows: First, the pipe 9 needs to be laid out and fixed in advance using a pipe rack to fix the position of the pipe 9. Then, two connecting cones 1 are inserted into the ports of the pipe 9 respectively. The length of the telescopic rod can be adjusted by manually rotating the connecting threaded sleeve 5 using the first nut 402 and the second knob 501 in conjunction with a wrench. The two connecting cones 1 can be pushed to move using multiple telescopic rods, so that the connecting cones 1 are squeezed to the ports of the pipe 9, sealing the connecting cones 1 and the pipe 9 together. The two pipes 9 are sealed together by the cooperation of the connecting cones 1 and the connecting hose 2.
