[0002] In the construction of water conservancy and hydropower projects, pipelines are a key component in water conveyance, drainage, irrigation and power generation. The reliability of their connections, construction efficiency and adaptability directly affect the overall quality and progress of the project.

[0003] Currently, most pipe connections use traditional methods such as flange connections, threaded connections, or welding. While these methods are widely used, they still present some challenges during actual construction. Flange connections require aligning bolt holes and tightening bolts individually; threaded connections require ensuring the threads are intact and have sufficient engagement length; and welding demands specialized trades and specific working environments. All these methods are time-consuming, especially in construction scenarios with numerous pipes, limited space, or frequent disassembly and assembly, leading to slow installation speeds and construction delays.

[0004] Therefore, in view of the above-mentioned technical problems, it is necessary to provide a pipe connection device for water conservancy and hydropower construction.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this utility model is to provide a pipe connection device for water conservancy and hydropower construction, which is easy to install and has good connection strength and sealing performance, and can meet the usage requirements of water conservancy and hydropower engineering construction.

[0007] To achieve the above objectives, a specific embodiment of this utility model provides the following technical solution: a pipe connection device for water conservancy and hydropower construction, comprising two pipe bodies, a connecting pipe being fitted onto both pipe bodies, and multiple connecting bosses being fixedly connected to the ends of the two pipe bodies that are close to each other. Each connecting boss has a limiting groove formed on the side away from the end of the pipe body. Multiple limiting airbags are fixedly connected to the inner wall of the connecting pipe, and an inflation component for inflating the limiting airbags is provided on the connecting pipe.

[0008] In one or more embodiments of this utility model, each of the limiting airbags is disposed in a limiting groove, and the limiting airbags, after being inflated, can fill the limiting groove to fix the two tubes.

[0009] In one or more embodiments of this utility model, a common air equalization channel is provided on the multiple limiting airbags, and an inflation port is provided on the air equalization channel. Each of the connecting protrusions has a notch that matches the air equalization channel.

[0010] In one or more embodiments of this utility model, the inflation component includes an inflation shell fixedly connected to a connecting pipe, an air outlet communicating with an inflation port is provided on the inflation shell, a piston is threadedly connected inside the inflation shell, and a sealing gasket is installed at one end of the piston near the air outlet.

[0011] In one or more embodiments of this utility model, the inflation component further includes an inflation head fixedly connected to the connecting pipe, the inflation head being connected to the inflation port, an air supply pipe being installed on the inflation head, the other end of the air supply pipe being connected to an inflation bladder, and a control valve being provided on the inflation head.

[0012] In one or more embodiments of this utility model, each of the tubes is provided with a fixing hole, and the connecting tube is provided with two connecting holes corresponding to the fixing holes. Each of the connecting holes is threaded with a fixing bolt, and the other end of each fixing bolt extends into the interior of the fixing hole.

[0026] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0027] like Figures 1 to 7 As shown in the figure, a pipe connection device for water conservancy and hydropower construction in one embodiment of this utility model includes two pipe bodies 1, and a connecting pipe 2 is fitted onto both pipe bodies 1. Washers 14 are fixedly connected to the ends of the two pipe bodies 1 that are close to each other. The connecting pipe 2 is a connecting device that connects the two pipe bodies 1. The washers 14 fixed to the ends of the pipe bodies 1 provide a certain buffering effect to prevent gaps at the connection and enhance the tightness of the connection. Dustproof bristles 13 are fixedly connected to the inner walls of both ends of the connecting pipe 2. The dustproof bristles 13 serve to clean and assist in sealing. When the pipe body 1 is inserted into the connecting pipe 2, the dustproof bristles 13 can scrape off contaminants such as mud, sand, and rust adhering to the outer wall of the pipe body 1. At the same time, the dustproof bristles 13 can also prevent fine particles such as external dust from entering the connection area, providing secondary protection.

[0028] Multiple connecting bosses 3 are fixedly connected to the ends of the two tube bodies 1 that are close to each other. Each connecting boss 3 has a limiting groove on the side away from the end of the tube body 1. Multiple limiting airbags 5 are fixedly connected to the inner wall of the connecting tube 2. The connecting tube 2 is equipped with an inflation component for inflating the limiting airbags 5. Each limiting airbag 5 is set in a limiting groove. After the limiting airbag 5 is inflated, it can fill the limiting groove and fix the two tube bodies 1. The connecting bosses 3 and the limiting grooves on them provide space for the limiting airbags 5 to expand and limit their expansion. The inflation component is a power source that can inflate the limiting airbags 5, causing them to expand in volume and tightly fill and fill the entire limiting groove. This securely locks the connecting tube 2 to the inner tube body 1 together.

[0029] Multiple limiting airbags 5 are provided with a common air distribution channel 6, and an inflation port 8 is provided on the air distribution channel 6. Each connecting boss 3 has a notch 4 that matches the air distribution channel 6. The air distribution channel 6 connects all the limiting airbags 5 into a whole and inflates them through a centralized inflation port 8. This ensures that the pressure can be transmitted quickly and evenly, so that they expand synchronously, thereby ensuring that the connection points are subjected to consistent force and avoiding connection misalignment or loosening caused by uneven force at a single point. The notch 4 on the connecting boss 3 provides space for the arrangement of the air distribution channel 6.

[0030] Please see Figure 4The inflation component includes an inflation shell 7 fixedly connected to the connecting pipe 2. The inflation shell 7 is provided with an air outlet that communicates with the inflation port 8. A piston 9 is threadedly connected inside the inflation shell 7. A sealing gasket 10 is installed at one end of the piston 9 near the air outlet.

[0031] In this embodiment, the inflatable shell 7 is a fixed air chamber. When the piston 9 is rotated, the rotational motion is converted into linear motion using a threaded drive, pushing the piston 9 inward. The sealing gasket 10 ensures the sealing of the piston 9. The movement of the piston 9 compresses the air inside the air chamber, generating high-pressure gas, which is then introduced into the limiting airbag 5. This method is compact, does not rely on external tools, and is easy to use.

[0032] To improve the flexibility of using this device, please refer to Figure 6 and Figure 7 The inflation component also includes an inflation head 15 fixedly connected to the connecting pipe 2. The inflation head 15 is connected to the inflation port 8, and an air supply pipe 18 is installed on the inflation head 15. The other end of the air supply pipe 18 is connected to the inflation bladder 17, and a control valve 16 is provided on the inflation head 15. In this way, the external inflation bladder 17 can be used as an independent gas source, connected to the inflation head 15 on the connecting pipe 2 through the air supply pipe 18. The control valve 16 can be used to open or close the inflation passage. In use, the operator can repeatedly press the inflation bladder 17 to inflate the limiting air bladder 5. This method provides relatively flexible operation and enhances the adaptability of the device under different working conditions.

[0033] To improve connection reliability, each tube body 1 is provided with a fixing hole 11, and the connecting tube 2 has two connecting holes corresponding to the fixing holes 11. Each connecting hole is threaded with a fixing bolt 12, and the other end of each fixing bolt 12 extends into the fixing hole 11. The fixing bolts 12 form an additional mechanical locking mechanism, providing double protection. After the limiting airbag 5 is inflated to initially fix the tube body 1, the fixing bolts 12 are screwed in, with their ends penetrating into the fixing holes 11 of the tube body 1, forming a rigid connection. This effectively prevents axial displacement or rotation of the tube body 1 under long-term vibration, impact loads, or unexpected pressure loss, greatly improving the long-term stability of the entire connection device.

[0034] Working principle: In use, first align the ends of the two tubes 1 that need to be connected, and then insert them into the connecting tube 2 respectively. During this process, multiple connecting protrusions 3 on the tube 1 will embed into the connecting tube 2, so that the limiting groove on each connecting protrusion 3 is aligned with the limiting airbag 5 on the inner wall of the connecting tube 2. At the same time, the notch 4 on the connecting protrusion 3 provides space for the air distribution channel 6, ensuring that the connecting tube 2 can be properly fitted. The gasket 14 at the end of the tube 1 makes the contact tighter and more reliable, preventing gaps. The dustproof bristles 13 can scrape off impurities on the surface of the tube 1. After ensuring the connection is clean and completing the above operations, gas can be injected into the limiting airbag 5 through the inflation component. The inflation method is not limited here and can be flexibly selected. As gas is continuously injected into the limiting airbag 5, it will expand. The expanded limiting airbag 5 can tightly fill and fill the entire space of the limiting groove. In this way, the connecting tube 2 and the internal tube body 1 can be firmly fixed to form a stable connection. To further improve the reliability of use, the fixing bolt 12 can also be passed through the connecting hole on the connecting tube 2 and screwed into the fixing hole 11 on the tube body 1 to form a double insurance of mechanical locking.
