Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0025] The present utility model provides a water conservancy pipeline connection device, as Figure 1 and Figure 3 shown, including a pipeline 1 and a connecting mechanism 2. A notch is provided on the circumferential side of one end of the pipeline 1, and the two pipelines 1 are connected through the connecting mechanism 2. The connecting mechanism 2 includes a connecting pipe 21, a pipe orifice 22, and a fixing component 23. The connecting pipe 21 is arranged between the two pipelines 1, the pipe orifice 22 is arranged at both ends of the connecting pipe 21, an annular groove 221 is provided on the side surface of the pipe orifice 22, and the end of the pipeline 1 provided with the notch is inserted into the annular groove 221. The annular groove 221 of the pipe orifice 22 at one end of the connecting mechanism 2 is sleeved on the end of a pipeline 1 provided with the notch, and the other pipeline 1 is inserted into the annular groove 221 of the pipe orifice 22 at the other end to connect the two pipelines 1.

[0026] As Figure 3 and Figure 4As shown, the pipe mouth 22 is a soft pipe, and a fixing ring 2211 is arranged on the outer wall surface of the annular groove 221, and the fixing ring 2211 is inserted into the groove of the pipe 1. A sealing ring 2212 is arranged on the inner wall surface of the annular groove 221, and the sealing ring 2212 is tightly attached to the inner wall of the pipe 1. A plurality of through holes 222 are opened through the circumference of the pipe mouth 22, and the through holes 222 are located between the sealing ring 2212 and the bottom of the annular groove 221, and fixing bolts 3 are arranged in the through holes 222. Tighten the fastening nut on the fixing bolt 3 located on the outside of the pipe mouth 22, so that the soft pipe mouth 22 is deformed inwardly toward the inside of the annular groove 221, and the fixing ring 2211 is inserted into the notch of the pipe 1 to fix the pipe 1 to prevent the pipe 1 from being separated from the connecting pipe 21 under the impact of the water flow when the water flows between the connecting pipe 21 and the pipe 1. At the same time, the sealing ring 2212 will be tightly attached to the inner wall of the pipe 1 to seal the inner wall of the pipe 1.

[0027] The material of the soft nozzle 22 can be rubber or plastic.

[0028] like Figure 2 and Figure 5 As shown, the connecting pipe 21 is a soft corrugated pipe, which can be bent and deformed. Corrugated protrusions 211 are evenly distributed along the axis in the length direction of the connecting pipe 21. A plurality of fixing components 23 are arranged on the peripheral side of the connecting pipe 21. The fixing components 23 include side seats 231 and flexible steel wires 232. A plurality of side seats 231 are arranged along the length direction of the connecting pipe 21. The side seats 231 are fixed on the corrugated protrusions 211. Figure 6 As shown, a hole 2311 is opened on the side of the side seat 231, and the flexible steel wire 232 is inserted into the holes 2311 of multiple side seats 231. The circumference of the flexible steel wire 232 is provided with a thread, one end of the flexible steel wire 232 is fixed with a plug 2321, and the other end of the flexible steel wire 232 is threadedly connected with a fixing nut 2322. When encountering a laying environment that requires a certain angle of deflection between the two groups of pipes 1, the connecting pipe 21 is bent and folded. After bending, the inner bend portion of the bending part of the connecting pipe 21 will shrink, and the distance between the side seats 231 will also be shortened. The portion of the flexible steel wire 232 passing through the side seat 231 will also be shortened. After bending, the outer bend portion of the bending part of the connecting pipe 21 will be elongated, and the distance between the side seats 231 will also be elongated. The portion of the flexible steel wire 232 passing through the side seat 231 will also be elongated. Twist the fixing nut 2322 to move it toward the side seat 231. The fixing nut 2322 and the plug 2321 are respectively clamped and fixed at both ends of multiple side seats 231, so that the connecting pipe 21 can maintain the bent state.

[0029] The material of the soft bellows connecting pipe 21 can be rubber or plastic.

[0030] Adopting the utility model, such as Figure 1 andFigure 2 As shown, the annular groove 221 at one end of the connecting mechanism 2 is sleeved on the end of a set of pipes 1 with a notch, and the other set of pipes 1 is inserted into the annular groove 221 at the other end of the pipe opening 22 to connect the two sets of pipes 1. Tighten the fastening nut on the fixing bolt 3 located outside the pipe opening 22, so that the soft pipe opening 22 is indented and deformed towards the inside of the annular groove 221, and the fixing ring 2211 is inserted into the notch of the pipe 1 to fix the pipe 1, preventing the pipe 1 from detaching from the connecting pipe 21 under the impact of water flow when the water flows between the connecting pipe 21 and the pipe 1. At the same time, the sealing ring 2212 will closely adhere to the inner wall of the pipe 1 to seal the inner wall of the pipe 1. When encountering a laying environment where the two sets of pipes 1 need to deflect a certain angle, the connecting pipe 21 is bent. The inner bent part of the bent part of the connecting pipe 21 after bending will shrink, and the distance between the side seats 231 will also shorten accordingly. The part of the flexible steel wire 232 passing through the side seats 231 will also shorten. The outer bent part of the bent part of the connecting pipe 21 after bending will elongate, and the distance between the side seats 231 will also elongate accordingly. The part of the flexible steel wire 232 passing through the side seats 231 will also elongate. Turn the fixing nut 2322 to move it towards the side seat 231. The fixing nut 2322 and the plug 2321 respectively clamp and fix the two ends of a plurality of side seats 231, so that the connecting pipe 21 can maintain the bent state.
