Description

Technical Field

[0001] This utility model relates to the field of pipeline connection technology, specifically a pipeline connection device for water conservancy and hydropower construction. Background Technology

[0002] Hydropower refers to the comprehensive utilization of water resources to develop water conservancy and hydropower projects for purposes such as irrigation, water supply, flood control, and power generation. Pipelines are an indispensable and crucial component in hydropower construction, playing a key role in transporting and discharging water resources. Due to the complexity of pipeline layouts at construction sites, connecting devices are often required between pipelines.

[0003] However, existing pipe connection devices for water conservancy and hydropower construction do not provide adequate sealing for irregular connecting pipes and are not effective in positioning the pipes. Therefore, they do not meet current requirements. To address this, we propose a new pipe connection device for water conservancy and hydropower construction. Utility Model Content

[0004] The purpose of this utility model is to provide a pipe connection device for water conservancy and hydropower construction, so as to solve the problems mentioned in the background art, such as the insufficient sealing effect of existing pipe connection devices for water conservancy and hydropower construction on irregular connecting pipes and the insufficient positioning effect of pipes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pipe connection device for water conservancy and hydropower construction, comprising a main body, connecting grooves provided on the inner sides of both ends of the main body, a fixing ring provided on the outer surface of the main body, reinforcing rods evenly arranged inside the fixing rings, positioning cylinders provided on both sides of the fixing rings, positioning rings provided at both ends of the positioning cylinders, the positioning rings being slidably connected to the reinforcing rods, positioning blocks provided at both ends of the reinforcing rods, an air cushion provided on the inner surface of the connecting grooves, air holes provided on the inner side of the air cushions, and sealing rings evenly arranged on the inner surface of the air cushions. An inflation valve is provided above the fixing ring. An annular groove is provided on the inner side of the positioning ring. Limiting rings are provided on both the upper and lower sides of the annular groove. An anti-slip pad is provided on the inner surface of the limiting ring. Limiting grooves are provided on the outer surfaces of both sides of the limiting ring. A limiting block is provided on the inner side of the limiting groove. An adjustment knob is provided on the outer surface of both the limiting block and the limiting ring. The adjustment knob is threadedly connected to the positioning ring. Positioning grooves are evenly distributed on the inner surface of the positioning ring. A buckle is provided on one side of the positioning block. A slot is provided on the other side of the positioning block. The positioning block and the positioning groove are connected by the buckle.

[0006] Preferably, the outer surface of the reinforcing rod is completely fitted with the inner surface of the fixing ring, and the reinforcing rod and the fixing ring are fixed by welding.

[0007] Preferably, one side of the positioning block is fully fitted with both ends of the reinforcing rod, and the positioning block and the reinforcing rod are fixed by welding.

[0008] Preferably, the outer surfaces of both ends of the positioning cylinder are completely fitted with the inner surface of the positioning ring, and the positioning cylinder and the positioning ring are fixed by welding.

[0009] Preferably, one end of the adjusting knob is slidably connected to the limiting ring and the limiting block, and the other end of the adjusting knob is provided with a knob.

[0010] Preferably, the inner surface of the fixing ring is completely fitted with the outer surface of the main body, and the fixing ring is fixed to the main body by welding.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses an air cushion, a sealing ring, and air holes provided inside the connecting groove. Gas is passed through an inflation valve to inflate the air cushion, so that the sealing ring provided on the inner surface of the air cushion can fit tightly against the connecting pipe. It can also fit the connecting pipe even if it is deformed, which increases the adaptability to different connecting pipes and improves the sealing performance of the pipe connection. 2. After inserting into the connecting groove, the positioning cylinder is pulled out along the reinforcing rod to make the positioning block and positioning ring snap together. At this time, the adjustment knob is turned to move the limiting ring downward, so that the anti-slip pad on the lower surface of the limiting ring is in close contact with the connecting pipe. Then, the limiting blocks on both sides of the limiting ring are used to insert the limiting blocks into the limiting groove to position the limiting ring, thereby improving the positioning effect of the limiting ring on the connecting pipe. Furthermore, pulling out the positioning cylinder to position the connecting pipe can reduce excessive pressure on the end of the connecting pipe, which can cause deformation and improve the sealing effect of the end of the connecting pipe.

[0026] Working principle: In use, the connecting pipe is inserted into the connecting groove 12 inside the main body 4. Gas is introduced through the air cushion 8, sealing ring 9, and air hole 11 inside the connecting groove 12, and inflated by the inflation valve 6. This allows the sealing ring 9 on the inner surface of the air cushion 8 to fit tightly against the connecting pipe. It also ensures a proper fit for deformed connecting pipes, increasing adaptability to different connecting pipes and improving the sealing performance of the pipe connection. After insertion into the connecting groove 12, the positioning cylinder 1 is pulled out along the reinforcing rod 2. The positioning block 10 is snapped into place with the positioning ring 7. Then, rotating the adjusting knob 5 moves the limiting ring 14 downwards, bringing the anti-slip pad 15 on the lower surface of the limiting ring 14 into close contact with the connecting pipe. Next, using the limiting blocks 16 on both sides of the limiting ring 14, the limiting blocks 16 are inserted into the limiting grooves 17 to position the limiting ring 14, improving its positioning effect on the connecting pipe. Furthermore, pulling out the positioning cylinder 1 to position the connecting pipe reduces excessive pressure on the end of the connecting pipe, thus reducing deformation and improving the sealing effect at the end of the connecting pipe.
