Description

Technical Field

[0001] This utility model relates to the field of water conservancy and hydropower engineering, and in particular to a water supply pipeline connection structure for water conservancy and hydropower engineering that is easy to install. Background Technology

[0002] In water conservancy and hydropower projects, the use of steel, concrete, or PVC water pipes with diameters of 100-1000mm is common. Traditional flange connections require alignment of bolt holes (8-12 bolts per pipe group), and installation of a single interface by two people takes at least one hour. Welded connections require professional welders and 24 hours of curing time after welding, which cannot meet the demands of tight deadlines. Flange gaskets are prone to leakage due to pipe misalignment (deviation ≥3mm) or uneven bolt tightening (leakage rate ≥0.5L / m·h). When using socket connections for concrete pipes, rubber rings are prone to detachment due to improper installation. Single connection structures can only accommodate pipes of the same material and diameter (e.g., steel flanges only connect steel pipes). This presents challenges when dealing with projects involving "steel pipe + PVC pipe" and "diameter transition sections." In scenarios such as these, customized transition joints are required, which is costly. Therefore, there is a need for a water supply pipeline connection structure for water conservancy and hydropower projects that is easy to install, requires no large machinery, has reliable sealing (low leakage rate), and is highly adaptable (compatible with multiple pipe materials).

To achieve the above purpose, this utility model adopts the following technical solution:

[0004] A water supply pipeline connection structure for easy installation in water conservancy and hydropower projects includes pipes to be connected, pipe fittings, external fixing components, and inner rubber gaskets. The pipes to be connected are arranged opposite each other. The pipe fittings are placed between the two sets of pipes to be connected, and both ends of the pipe fittings are inserted into the opposite ends of the pipes to be connected. The inner rubber gaskets cover the outside of the connection point between the pipes to be connected and the pipe fittings. The external fixing components are fixed to the outside of the inner rubber gaskets.

[0005] Based on the above technical solution, the external fixing component consists of split covered tubes, fixed edges of the covered tubes, mating grooves, locking bolts, and an inner convex fixing waistline. The split covered tubes are arranged opposite each other, and the fixed edges of the covered tubes are respectively located on the upper and lower sides of the split covered tubes. The mating grooves are located on the inner side of the contact surface of the fixed edges of the covered tubes, and the mating grooves on the fixed edges of the two covered tubes are correspondingly fitted together.
