Description
Technical Field
[0001] This utility model relates to the field of water supply and drainage engineering pipeline technology, specifically a water supply and drainage engineering pipeline connection device. Background Technology
[0002] Water supply pipelines primarily function to transport domestic water, industrial water, and fire-fighting water. They deliver drinking water that meets hygiene standards from water sources or water treatment plants to households, meeting people's daily needs for drinking, cooking, and washing. They also provide water for industrial production, such as cooling water and process water, ensuring the normal operation of industrial production. Furthermore, they provide fire-fighting water, quickly providing sufficient water to ensure the smooth conduct of fire-fighting operations and protect people's lives and property. Drainage pipelines are mainly used to collect and discharge domestic sewage, industrial wastewater, and rainwater. They collect domestic sewage generated in daily life, such as fecal wastewater and washing wastewater, and transport it to sewage treatment plants for treatment, preventing indiscriminate discharge and environmental pollution. They collect various wastewater generated during industrial production, such as wastewater containing heavy metals, organic matter, acids, and alkalis, and transport it to appropriate sewage treatment facilities for treatment to meet discharge standards before discharge or reuse. During rainfall, they promptly collect and discharge rainwater to prevent urban flooding and protect urban infrastructure and people's lives and property.
[0003] Existing water supply and drainage pipelines mostly use flanges and hot-melt welding for connection. Although these connection methods can connect the pipes, the joints are still relatively weak. Under long-term water pressure, the joints may loosen and expand, leading to water leakage. To address this, we provide a water supply and drainage pipeline connection device to solve these problems. Utility Model Content

[0027] 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.
[0028] like Figure 1-5 As shown, this utility model provides a technical solution: a water supply and drainage engineering pipeline connection device, including a connecting pipe 1 and a base plate 2. The base plate 2 provides support for the components to be mounted. Two sets of support seats 3 are installed on the upper surface of the base plate 2, and the two sets of support seats 3 are symmetrical. Each set of support seats 3 consists of two seats, and the two sets of support seats 3 are symmetrical. The support seats 3 provide support force to both ends of the lower arc-shaped bracket 5 to maintain the stability of the lower arc-shaped bracket 5.
[0029] Both sets of support bases 3 have slide rails 4 on their inner sides, which provide movement space for the lower arc-shaped bracket 5. The lower arc-shaped bracket 5 is slidably connected to the inner wall of the slide rail 4. An upper arc-shaped bracket 6 is set above the lower arc-shaped bracket 5. The connecting pipe 1 is located inside the lower arc-shaped bracket 5 and the upper arc-shaped bracket 6. The lower arc-shaped bracket 5 and the upper arc-shaped bracket 6 wrap the connecting pipe 1 inside, maintaining the stability of the connecting pipe 1. After the connecting pipe 1 is placed inside the lower arc-shaped bracket 5 and the upper arc-shaped bracket 6, the upper arc-shaped bracket 6 and the lower arc-shaped bracket 5 are connected together by locking bolts, tightly wrapping the connecting pipe 1 inside.
[0030] A lead screw 7 is rotatably connected to the inner wall of the support base 3. The outer surface of the lead screw 7 is threadedly connected to the inner wall of the lower arc-shaped bracket 5. One end of the lead screw 7 is connected to a four-corner head 8, which facilitates the connection of a wrench or other tools. The four-corner head 8 is rotated by the wrench or other tools, and the rotation of the four-corner head 8 drives the lead screw 7 to rotate simultaneously. The rotation of the lead screw 7 generates power, which provides power for the lower arc-shaped bracket 5 to move.
[0031] There are two connecting pipes 1, and the two connecting pipes 1 are symmetrical. Each of the two connecting pipes 1 is connected to a flange 9 at the opposite end. The two connecting pipes 1 are connected together through the flange 9. The locking bolt passes through the inside of the flange 9, and the two flanges 9 are tightly contacted together by the locking bolt.
[0032] The inner walls of both the lower arc-shaped bracket 5 and the upper arc-shaped bracket 6 are connected with inverted teeth 10. The outer surface of the inverted teeth 10 contacts the outer surface of the connecting pipe 1. The inverted teeth 10 increase the friction between the lower arc-shaped bracket 5 and the upper arc-shaped bracket 6 and the connecting pipe 1, thereby improving the stability of the connecting pipe 1.
[0033] The inner wall of the slide 4 is connected to the positioning slide rail 11, and the inner wall of the lower arc-shaped bracket 5 is provided with a positioning groove 12. The inner wall of the positioning groove 12 is slidably connected to the outer surface of the positioning slide rail 11. The positioning slide rail 11 provides support for the lower arc-shaped bracket 5 and maintains the stability of the lower arc-shaped bracket 5 when it moves. The lower arc-shaped bracket 5 receives the support force of the positioning slide rail 11 through the positioning groove 12.
[0034] A four-corner block 13 is connected to one side of the support base 3. A pressure plate 14 is sleeved on the outside of the four-corner block 13. The pressure plate 14 has a bending function. The outer surface of the pressure plate 14 contacts the outer surface of the four-corner head 8. The four-corner block 13 provides support for the pressure plate 14 and prevents the pressure plate 14 from rotating. One side of the pressure plate has a protrusion. After the four-corner head 8 stops rotating, the protruding part of the pressure plate 14 is bent to contact the four-corner head 8, providing resistance to the four-corner head 8, preventing the lead screw 7 and the four-corner head 8 from rotating, and maintaining the stability of the lead screw 7.
[0035] Four fixing holes 15 are provided on the inner side of the base plate 2, and the four fixing holes 15 are located at the four corners of the base plate 2. The fixing holes 15 are used to pass fixing bolts to fix the base plate 2 and maintain the stability of the base plate 2. The fixing holes 15 are rectangular in shape, and the rectangular fixing holes 15 facilitate the fine adjustment of the position of the base plate 2.
[0036] Both flanges 9 have a sealing groove 16 on their inner side. A sealing gasket 17 is installed inside the sealing groove 16. The sealing gasket 17 is made of rubber. The sealing gasket 17 fills the gap between the two flanges 9, improving the sealing performance between the two flanges 9. The sealing groove 16 wraps around the sealing gasket 17, thereby increasing the stability of the sealing gasket 17 and preventing the sealing gasket 17 from deforming when squeezed.
[0037] Working principle: In use, first place the two connecting pipes 1 into the lower arc-shaped bracket 5, then place the upper arc-shaped bracket 6 on top of the lower arc-shaped bracket 5, and then use locking bolts to tightly contact the upper arc-shaped bracket 6 and the lower arc-shaped bracket 5 together, and tightly wrap the connecting pipes 1 inside the upper arc-shaped bracket 6 and the lower arc-shaped bracket 5. Then, rotate the screw 7 through the four-corner head 8. The rotation of the screw 7 pushes the upper arc-shaped bracket 6 to move. As the upper arc-shaped bracket 6 moves, it drives the two connecting pipes 1 to tightly contact each other, and at the same time, it tightly contacts the two flanges 9 together. Then, pass the locking bolt through the flange 9 and tighten the locking bolt. Then, the bending pressure plate 14 contacts the four-corner head 8, restricting the rotation of the screw 7 and the four-corner head 8.
