[0019] Example 1: like Figure 1-4 This invention discloses a pipeline interface protection cap device, specifically designed for the protection of various pipeline interfaces during the construction of thermal power plants, hydropower stations, and pumped storage power stations. It effectively prevents blockages or cleaning difficulties caused by concrete pouring, construction waste, etc., falling into the pipeline. The device includes a protective sleeve 1 with a single-sided opening size adapted to common pipeline interfaces, stably covering the interface. The sleeve 1 has a robust overall structure, capable of withstanding certain external impacts, preventing damage and loss of protective function due to external collisions. The sleeve 1 is equipped with multiple sets of elastic limiting structures 3 and support structures. The elastic limiting structures 3 securely fix the sleeve 1 to the pipeline interface, while the support structures provide support, preventing tilting or displacement under its own weight or slight external forces, further ensuring the protective effect. The elastic limiting structure 3 includes multiple clamping rods 8. The clamping rods 8 penetrate the protective sleeve 1 and slide within it, allowing the clamping rods 8 to move freely radially along the protective sleeve 1 to adjust the clamping position according to the outer diameter of the pipeline. A limiting head 9 is provided at one end of the clamping rod 8 located outside the protective sleeve 1. The limiting head 9 not only prevents the clamping rod 8 from completely sliding into the protective sleeve 1 under the action of the elastic element 10, but also provides a force application point for the operator to manually adjust the position of the clamping rod 8. An elastic element 10 is fitted onto the clamping rod 8. Both ends of the elastic element 10 are connected to the outer wall of the protective sleeve 1 and the limiting head 9, respectively. In its natural state, the elastic element 10 is under a certain compression, continuously applying a force towards the inside of the protective sleeve 1 to the clamping rod 8, ensuring that the clamping rod 8 always exerts a clamping force against the outer wall of the pipeline. One end of the clamping rod 8 located inside the protective sleeve 1 is fixedly connected to the clamping plate 11. The clamping plate 11 is in direct contact with the outer wall of the pipeline. By increasing the contact area with the outer wall of the pipeline, the stability of clamping is improved, and damage to the outer wall of the pipeline is avoided due to the clamping rod 8 directly contacting the pipeline. In the preferred embodiment, the multiple sets of elastic limiting structures 3 are three sets, which are evenly distributed around the axis of the protective sleeve 1. This even distribution ensures that the clamping force on the protective sleeve 1 is evenly distributed around the outer periphery of the pipeline, preventing the protective sleeve 1 from tilting or the pipeline from being damaged due to uneven force, and further improving the stability of the connection between the protective sleeve 1 and the pipeline. In a preferred embodiment, the top surface of the top clamping plate 11 is provided with multiple sets of anti-slip strips 12. The anti-slip strips 12 can increase the friction between the top clamping plate 11 and the outer wall of the pipeline, effectively preventing the protective sleeve 1 from sliding relative to each other due to vibration, slight collisions or other factors during use, ensuring that the protective sleeve 1 always remains in the correct protective position, and improving the reliability of the protection. In a preferred embodiment, the tightening surface of the tightening plate 11 is provided with an arc groove 13. The shape of the arc groove 13 is adapted to the curvature of the outer wall of common pipelines, which allows the tightening plate 11 to better fit the outer wall of the pipeline. This not only increases the contact area between the tightening plate 11 and the pipeline, but also plays a certain positioning role for the pipeline, preventing the tightening plate 11 from shifting during the tightening process, and further improving the tightening effect and the stability of the protective sleeve 1. In a preferred embodiment, the feed end of the top clamping plate 11 is provided with a guide arc plate 14. When the protective sleeve 1 is installed onto the pipeline interface, the guide arc plate 14 can guide the pipeline to smoothly enter the interior of the protective sleeve 1 and accurately connect with the top clamping plate 11, reducing installation difficulty and improving installation efficiency. At the same time, it avoids damage to the pipeline or the top clamping plate 11 due to collision between the pipeline and the top clamping plate 11 during the installation process. In a preferred embodiment, the support structure includes mounting plates 4 symmetrically arranged on the protective sleeve 1. The mounting plates 4 are fixedly connected to the protective sleeve 1, providing a stable installation foundation for the support structure. The mounting plates 4 have limiting grooves 5, the length and width of which are designed according to actual support requirements. Limiting sliders 6 cooperate with the limiting grooves 5, allowing them to slide freely along the grooves to adjust the support position and height of the support legs 7 according to actual site conditions. Support legs 7 are fixedly connected to the limiting sliders 6. The support legs 7 possess sufficient strength and rigidity to stably support the protective sleeve 1. Anti-slip structures can be installed at the bottom of the support legs 7 as needed to further improve support stability. In a preferred embodiment, one end of the limiting groove 5 is open and the other end is closed. The open end facilitates the installation and removal of the limiting slider 6 and the support leg 7, while the closed end restricts the sliding range of the limiting slider 6, preventing it from sliding out of the closed end of the limiting groove 5, ensuring the integrity and stability of the support structure during use, and avoiding support failure due to the limiting slider 6 falling off. In a preferred embodiment, the closed end of the protective sleeve 1 is provided with an observation window 2. The observation window 2 is made of transparent material, allowing operators to clearly observe the internal condition of the pipeline interface without disassembling the protective sleeve 1, such as whether foreign objects have entered or whether there are any abnormalities in the pipeline interface. This facilitates daily inspection and maintenance, reduces unnecessary disassembly operations, improves work efficiency, and avoids damage to the pipeline interface or impairment of the protective effect caused by frequent disassembly of the protective sleeve 1. In a preferred embodiment, the protective sleeve 1 is coated with red, green, or yellow paint. These bright and eye-catching colors make the protective sleeve 1 easier for operators to identify in the complex environment of the construction site, facilitating quick location of the pipeline interface. It also serves as a warning, reminding on-site personnel to pay attention to the protective sleeve 1 and the pipeline interface, preventing damage due to misoperation or negligence. In a preferred embodiment, the elastic element 10 is a stainless steel compression spring, and its surface is coated with a polytetrafluoroethylene (PTFE) anti-corrosion coating. The stainless steel material ensures that the elastic element 10 possesses good strength, toughness, and corrosion resistance, guaranteeing its long-term stable operation in harsh construction environments (such as humid conditions or corrosive gases), preventing rust or breakage. The PTFE anti-corrosion coating provides excellent corrosion resistance, further enhancing the corrosion resistance of the elastic element 10, extending its service life, and reducing friction between the elastic element 10 and other components, ensuring the stable performance of its elastic properties.

[0020] Example 2: like Figure 1-4 The working principle of this utility model is as follows: When in use, hold the protective sleeve 1, and then pull a set of clamping rods 8 with one hand to move the clamping plate 11 in one position inside the protective sleeve 1 toward the inner wall of the protective sleeve 1, thereby leaving enough space. Then, put the tube head to be protected into the protective sleeve 1, and release the clamping rods 8. The three sets of clamping plates 11 will fit against the outer wall of the tube head and, with the cooperation of the same elastic element 10, will evenly clamp and limit the position, keeping the tube head in the center position inside the protective sleeve 1 and stable. Alternatively, the sleeve 1 can be directly placed on the pipe head that needs protection. With the cooperation of the guide arc plate 14, the top plates in the multiple sets of elastic limiting structures 3 will be automatically squeezed open until the pipe head is inserted to a certain depth. Then you can release your hand. The three sets of top plates 11 are attached to the outer wall of the pipe head. With the cooperation of the same elastic element 10, they are evenly tightened and limited, keeping the pipe head in the center position inside the protective sleeve 1 and stable.

[0021] The beneficial effects of this utility model are: it can accurately protect pipe interfaces, reduce damage caused by human factors and construction, and is flexible and reliable in fixing, effectively protecting pipe openings and allowing for reuse; it has a good protection effect on pre-buried pipe interfaces, and with the aid of color-coded reminders and warnings, it avoids pipe blockage caused by human or accidental damage, prevents other debris from entering the pipes and making cleaning inconvenient, thus becoming a quality hazard that affects later operation; the overall manufacturing cost is low, assembly and use are simple, disassembly is convenient, and it is highly practical.
