Description

Technical field:

[0001] The utility model relates to the technical field of water conservancy pipelines, in particular to a water conservancy pipeline connection device with reinforced connection. Background technology:

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. Water pipelines refer to water from reservoirs, surge tanks, to turbines or from water pumps to high places, as well as water pipes buried at the bottom of earth-rock dams, underground or in the open air. They can be used for irrigation, hydropower generation, urban water supply, drainage, sediment discharge, reservoir emptying, construction diversion coordination and spillway flood discharge.

[0003] For example, the authorization announcement number "CN218914056U" is named a water conservancy pipeline connection device. Although the detachable design facilitates the assembly and disassembly of the locking arc piece, the buffer cotton layer and rubber wear-resistant layer on the outer surface of the locking arc piece can enhance the anti-collision and wear resistance of the connection frame. However, the existing water conservancy pipeline connection equipment uses the locking arc piece to clamp the outside of the water conservancy pipeline connection to play a fixing role. However, water will flow through the inside of the water conservancy pipeline for a long time, and the shock and impact force generated by the flow of water will often act on the connection part. In this way, the locking arc piece and the pipeline fitting part will loosen due to the vibration caused by the pipeline being flushed by the water flow. The fixing effect of the loose locking arc piece is weakened, which can easily lead to the water conservancy pipeline connection device. The connection is not firm enough.

[0004] At the same time, the existing water conservancy pipeline connection equipment, since the locking arc piece adopts a threaded straight rod to drive the nut to limit and position the connection seat, the nut on the threaded straight rod lacks a limiting and protective structure. Therefore, once someone accidentally touches the nut and causes the nut to rotate and move, the tightening effect of the nut on the connection seat will be weakened, and a certain gap will be generated between the locking arc piece and the internally tightened pipe. The gap will cause the inside of the pipe to shake due to the flushing of water flow, which will affect the sealing of the connection, resulting in the problem of weakened connection sealing of the water conservancy pipeline connection equipment.

[0040] Working principle:

[0041] When the reinforced water conservancy pipeline connection equipment is used to reinforce the connection of the water conservancy pipeline:

[0042] Reinforced hydraulic pipeline connection equipment reinforcement and tightening structure:

[0043] The connecting piece 2 is a connecting flange of the pipeline, and the two water conservancy pipes 1 can be closely fitted and docked through the flange. The two fixing rings 41 are fixedly sleeved on the outer wall of the water conservancy pipe 1. The fixing ring 41 is fixedly sleeved on the outer side of the water conservancy pipe 1 by welding.

[0044] The tightening reinforcement structure of the hydraulic pipeline connection equipment:

[0045] The extension plate 54 extends outward from the outside of the fixing ring 41. When the threaded column 55 is rotated and screwed on the extension plate 54, the rotating threaded column 55 drives the threaded block 53 to move upward. The threaded block 53 moving upward pulls the flip rod 52 to lift along the connecting shaft 51. In this way, the flip rod 52 lifted at one end drives the clamping rod 56 at the other end to press downward through the lever principle. The downward force of the clamping rod 56 pushes the clamping strip 42 to be firmly engaged between the fixing ring 41 and the connecting piece 2, and it is not easy to loosen.

[0047] When the arc hoop 61 is sleeved on the outside of the sealing gasket 43, the insertion block 73 on one side of the arc hoop 61 will drive multiple card blocks 75 to be inserted into the trapezoidal groove 74. The trapezoidal groove 74 is a right-angled trapezoid. The hypotenuse of the right-angled trapezoid will fit with the hypotenuse of the card block 75. The card block 75 pushes the spring 76 inward to contract. Then, when the inner space of the trapezoidal groove 74 corresponds to the card block 75, the card block 75 is inserted between the trapezoidal blocks 74 under the reverse elastic force of the spring 76. The straight edge of the trapezoidal block 74 will limit the movement of the card block 75. Only when the operator pulls the slider 72 backward to move, and the slider 72 drives the multiple card blocks 75 to slide inward, can the insertion rod 73 be pulled out and separated.

[0048] Arc hoop locking structure of the reinforced water conservancy pipeline connection equipment:

The threaded short rod 66 and the threaded long rod 63 have opposite thread directions, so that one end of the threaded long rod 63 is fixed to the mounting seat 62. Therefore, when the first nut 65 on the outer side of the threaded long rod 63 is screwed, the movable seat 63 is pushed to move toward the mounting seat 62, and the movable seat 63 squeezes the mounting seat 63 to achieve the tightening effect of the arc hoop 61. The second nut 67 is sleeved on the outer side of the threaded short rod 66 and screwed. The second nut 67 will clamp the position of the first nut 65 through the reverse thread, so that the first nut 65 will not fall off easily, thereby improving the tightening effect of the arc hoop 61.
