[0035] Reference Figure 1-Figure 3 The inner side wall of the connecting flange 301 is fixedly connected to the right end of the drain pipe 1, and the two are fixed by welding. One end of the connecting spring 304 is fixedly connected to the inner wall of the plug-in ring 305, and the other end of the connecting spring 304 is fixedly connected to the outer wall of the rubber pad 303. The outer wall of the rubber pad 303 is slidably connected to the inner wall of the connecting flange 301. The elasticity of the connecting spring 304 makes the rubber pad 303 as a whole have a reset and support effect, and the other end of the connecting spring 304 is fixedly connected to the outer wall of the slider, and the rubber pad 303 is driven by the slider to move. The outer wall of the support flange 302 is provided with a plug-in groove 306, and the plug-in groove 306 is set to a truncated cone shape. The outer wall of the plug-in ring 305 is plugged into the inner wall of the plug-in groove 306. The two are plugged in and then squeeze the sealing ring to improve the sealing performance. The top of the rubber pad 303 contacts the inner side wall of the plug-in groove 306, and the contact between the two does not affect the plug-in of the plug-in groove 306 and the plug-in ring 305.

[0036] Reference Figure 2 , Figure 5 and Figure 6The protective mechanism 4 includes a cylindrical plate 401, and a fixing ring 402 is fixedly connected to the right end of the cylindrical plate 401, and the movement trajectories of the two are the same. The outer wall of the connecting pipe 2 is slidably connected to a protective cylinder 403, which can be protected by sliding. When installing the bolts, the protective cylinder 403 can be removed for installation. The top of the protective cylinder 403 is fixedly connected to a supporting block 404, and the inner wall of the supporting block 404 is elastically connected to a plug-in column 405 through a reset spring 406. The plug-in column 405 penetrates and is slidably connected to the inner wall of the supporting block 404. The penetration setting is convenient for relevant personnel to move the plug-in column 405, and the bottom end of the plug-in column 405 is provided with an inclined surface, which is convenient for installation. The outer wall of the fixing ring 402 is plugged into the inner wall of the protective cylinder 403, and the plug-in of the two has a preliminary positioning effect. The inner wall of the cylindrical plate 401 is slidably connected to the outer wall of the drain pipe 1, and protection can be carried out by sliding. When installing the bolts, the cylindrical plate 401 can be removed for installation.

[0037] Reference Figure 2 , Figure 5 and Figure 6 One end of the reset spring 406 is fixedly connected to the inner wall of the support block 404, and the other end of the reset spring 406 is fixedly connected to the outer wall of the plug-in column 405. The outer wall of the plug-in column 405 is slidably connected to the inner wall of the support block 404. The elasticity of the reset spring 406 makes the plug-in column 405 have reset and limiting functions. The bottom end of the plug-in column 405 is plugged into the inner walls of the protective tube 403 and the fixing ring 402. The two are plugged and placed on the cylindrical plate 401 to move. The right end of the cylindrical plate 401 contacts the left end of the protective tube 403. The contact between the two can protect the flange and the bolts.

[0038] Working principle: When relevant personnel need to install and connect two sets of water conservancy pipes, that is, the drainage pipe 1 and the connecting pipe 2 mentioned in the text, first stretch the sealing ring and then put it on the outer wall of the plug-in ring 305, so that the sealing ring contacts the rubber pad 303. When the sealing ring is stretched, the staff lets go. At this time, due to the elasticity of the sealing ring, it will shrink and squeeze the rubber pad 303, causing the rubber pad 303 to move. When the rubber pad 303 moves to a certain position, it will be in a balanced state. At this time, the plug-in ring 305 can be plugged into the plug-in groove 306. After the plug-in is completed, the connecting flange 301 and the support flange 302 squeeze the rubber pad 303 to achieve sealing. At this time, the bolts are installed to complete the connection limit.

[0039] After the bolt connection is completed, the cylindrical plate 401 and the protective tube 403 are plugged in. During the plugging process, the fixing ring 402 will first contact the bottom end inclined surface of the plug-in column 405, thereby causing the plug-in column 405 to move upward. When the fixing ring 402 and the protective tube 403 are fully contacted and plugged in, the plug-in column 405 is reset due to the elasticity of the reset spring 406, so that the plug-in column 405 plugs and fixes the fixing ring 402. The operation is simple and convenient. After fixation, the cylindrical plate 401 and the protective tube 403 will completely cover the bolts, reducing the oxidation of the bolts and thus increasing their service life.
