Technical Field

[0001] This utility model relates to the field of water conservancy and hydropower, and in particular to a fixing device for buried pipes in water conservancy and hydropower projects. Background Technology

[0002] An existing patent (publication number: CN213745214U) discloses a fixing device for buried pipes in water conservancy and hydropower projects, comprising a semi-ring support block, side strip blocks, a rectangular plate, a semi-ring pressure block, a screw, and an L-shaped block. Side strip blocks are installed on both end faces of the semi-ring support block, and each of the side strip blocks has a strip-shaped hole on one side wall. The bottom center of the rectangular plate is fixedly connected to the top end face of the corresponding side strip block, and two symmetrical drill bit insertion holes are opened on one side wall of the rectangular plate. The two ends of the semi-ring pressure block are fixedly connected to the side walls of the vertical blocks of the two corresponding L-shaped blocks. The screw is rotatably installed between the upper and lower walls of the corresponding strip-shaped holes, and the screw is threadedly connected to the transverse block of the L-shaped block. However, this device lacks an auxiliary fixing and reinforcement structure near the pipe joint during use, making it prone to breakage at the pipe joint. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of the existing technology by providing a fixing device for water conservancy and hydropower buried pipes. This device uses a fixing frame, positioning rod, and U-shaped clamping plate to fix and reinforce the connection points of adjacent water conservancy and hydropower buried pipes, preventing adjacent water conservancy and hydropower buried pipes from breaking at the connection point during use.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A fixing device for buried water conservancy and hydropower pipes includes a water conservancy pipe, a fixing sleeve, a horizontal connecting rod, a limiting ring plate, a positioning tie rod, a tie rod side plate, a fixing disc, a U-shaped clamping plate, a first arc rod, a second arc rod, and a locking sleeve. The water conservancy pipe has a pipe flange, adjacent pipe flanges are fitted together and connected by multiple bolts. The water conservancy pipe is adapted to the fixing sleeve and is inserted into the fixing sleeve. The fixing sleeve has a sleeve side plate on its side, and multiple sleeve side plates are evenly distributed on the axial side of the fixing sleeve. One end of the horizontal connecting rod is close to the fixing sleeve, and the other end of the horizontal connecting rod is connected to the limiting ring plate. The water conservancy pipe is adapted to the limiting ring plate and is inserted into the limiting ring plate. The side of the limiting ring plate is fitted with the pipe flange.

[0006] The positioning tie rod has a tie rod side plate on its side. The positioning tie rod passes through the sleeve side plate. The side of the tie rod side plate is in contact with the sleeve side plate. The side of the positioning tie rod is connected to a fixed disc. The symmetrical fixed discs are in contact with each other. The outer side of the water conservancy pipeline is in contact with the horizontal connecting rod. One end of the U-shaped clamp is connected to the second arc rod, and the other end of the U-shaped clamp is connected to the first arc rod.

[0007] The U-shaped card plate has an inner groove, and side grooves at both ends of the inner groove. Symmetrical fixing discs are adapted to the inner groove and inserted into the inner groove. Positioning rods are adapted to the side grooves and inserted into the side grooves. The second arc-shaped rod has a threaded connecting post on its side, and the first arc-shaped rod is connected to a circular anti-detachment disc on its side. Beneficial effects

[0008] 1. In this utility model, the two ends of the horizontal connecting rod are respectively connected to the limiting ring plate and the fixing sleeve. The limiting ring plate and the fixing sleeve are both fitted onto the water conservancy pipeline. The horizontal connecting rod, the fixing sleeve, and the limiting ring plate form a fixing frame. The fixing frame is fitted onto the water conservancy pipeline and is limited by the pipeline flange, so that the fixing frame is close to the end of the water conservancy pipeline. The positioning tie rod passes through the side plate of the sleeve. The symmetrical positioning tie rod applies tension to the symmetrical fixing frame, so that the fixing frame is fixed to the side of the pipeline flange, ensuring the fixation of both. The symmetrical fixing disc is inserted into the inner groove of the clamping plate. The symmetrical fixing disc is positioned by the U-shaped clamping plate, so that the two are tightly aligned. In this way, the symmetrical fixing frame clamps the adjacent pipeline flange, preventing the connection between the two in water conservancy and hydropower buried pipes from being insufficiently tight.

[0009] 2. This utility model has a locking sleeve fitted onto the first arc-shaped rod, and a circular anti-detachment disc connected to the first arc-shaped rod. The circular anti-detachment disc prevents the locking sleeve from falling off the first arc-shaped rod in the water conservancy and hydropower buried pipe. During use, the adjacent threaded connecting column is in contact with the circular anti-detachment disc. At this time, the locking sleeve can be rotated to make the threaded connecting column threadedly connected to the inner thread groove of the locking sleeve. Three U-shaped clamps are connected end to end through the locking sleeve to form a complete ring, preventing the U-shaped clamps from falling off the fixed disc in the water conservancy and hydropower buried pipe. When in use, this device fixes and reinforces the connection of adjacent water conservancy pipelines through the cooperation of the fixing frame, positioning tie rod, and U-shaped clamps, preventing adjacent water conservancy pipelines from breaking or snapping at the connection point during use.
