DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] When implementing: Figure 1-4 As shown, a water conservancy project pipeline connection device includes: a connecting pipe 1, both ends of the connecting pipe 1 are connected to a hose 101, and the other end of the hose 101 is connected to a connecting piece 103; a connecting assembly 2, the connecting assembly 2 is arranged at an end of the connecting piece 103 away from the hose 101, and the connecting assembly 2 is used to connect the water conservancy project pipeline with the connecting pipe 1; wherein the connecting assembly 2 includes two flanges 201, one side of one flange 201 is fixedly connected to an end of the connecting piece 103 away from the connecting piece 103, and the other end of the other flange 201 is fixedly connected to an end of the water conservancy project pipeline to be connected;

[0021] The hoses 101 arranged at both ends of the connecting pipe 1 can achieve the effect of partially or completely connecting the two water conservancy project pipelines when an error occurs in the connection of the two water conservancy project pipelines, thereby improving the installation effect and avoiding the problem that the traditional water conservancy project pipelines are inconvenient to move for subsequent connection due to position deviation after placement.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, the first sealing ring 203 and the second sealing ring 205 are respectively embedded and installed on the opposite sides of the two flanges 201, the diameters of the first sealing ring 203 and the second sealing ring 205 are equal, and the surface of the flange 201 is provided with evenly distributed mounting holes 202, and the surface of one side of the flange 201 is provided with a fastening bolt 208, one end of the fastening bolt 208 is provided with an enlarged portion 207, and the other end of the fastening bolt 208 passes through two corresponding mounting holes 202 and is threadedly connected with a nut 210, the surface of the first sealing ring 203 is fixedly connected with evenly distributed protrusions 204, and the second sealing ring 205 is provided with evenly distributed grooves 206 on the side close to the first sealing ring 203.

[0023] When the two flanges 201 are butted, the first sealing ring 203 and the second sealing ring 205 are in close contact, thereby achieving sealing of the connection between the flanges 201. During this process, the protrusion 204 can be inserted into the inside of the groove 206, further improving the connection strength between the first sealing ring 203 and the second sealing ring 205, thereby reducing leakage at the connection between the water conservancy project pipeline and the connector 103, and effectively improving the sealing strength;

[0024] The cooperation between the nut 210 and the fastening bolt 208 can limit the position of the two flanges 201, and the operation is simple.

[0025] like Figure 1 , Figure 2 and Figure 4 As shown, the enlarged portion 207 and the opposite side of the nut 210 are fixedly connected with a sealing ring 209, and the surface of the connecting pipe 1 is fixedly connected with two symmetrically distributed mounting blocks, and the surface of the mounting block is provided with a connecting bolt 102, and the lower end of the connecting bolt 102 is threaded through the mounting block and fixedly connected with a drill bit;

[0026] By rotating the connecting bolt 102, the connecting bolt 102 can gradually pass through the mounting block and drive the drill bit into the ground, thereby improving the stability of the connecting pipe 1, ensuring the position of the connecting pipe 1, and reducing the possibility of falling off. The sealing ring 209 on the opposite side of the enlarged part 207 and the nut 210 can be pressed against the inner wall of the mounting hole 202 on the flange 201 by the enlarged part 207 and the nut 210 after the fastening bolt 208 and the nut 210 are threadedly tightened, thereby achieving sealing of the mounting hole 202, avoiding moisture invading the fastening bolt 208 during use and causing rust on the fastening bolt 208, so as to facilitate later maintenance and disassembly.

[0027] When the utility model is in use, by rotating the connecting bolt 102, the connecting bolt 102 can gradually pass through the mounting block to drive the drill bit into the ground, thereby improving the stability of the connecting pipe 1, ensuring the position of the connecting pipe 1, and reducing the possibility of falling off. After the fastening bolt 208 and the nut 210 are threadedly tightened, the sealing ring 209 on the opposite side of the enlarged part 207 and the nut 210 can be pressed against the sealing ring 209 by the enlarged part 207 and the nut 210, so that it is tightly attached to the inner wall of the mounting hole 202 on the flange 201, thereby achieving the sealing of the mounting hole 202, avoiding the situation that the fastening bolt 208 is rusted due to moisture intrusion during use, so as to facilitate the later maintenance and disassembly, and the two sides of the connecting pipe 1 can be connected. The hose 101 arranged at the end can use the hose 101 to partially or completely connect the two water conservancy project pipes when an error occurs in the connection of the two water conservancy project pipes, thereby improving the installation effect and avoiding the problem that the traditional water conservancy project pipe is inconvenient to move for subsequent connection due to position deviation after placement. When the two flanges 201 are docked, the first sealing ring 203 and the second sealing ring 205 are tightly attached to achieve sealing at the connection of the flanges 201. During this process, the protrusion 204 can be inserted into the inside of the groove 206, further improving the connection strength between the first sealing ring 203 and the second sealing ring 205, thereby reducing leakage at the connection between the water conservancy project pipe and the connector 103, and effectively improving the sealing strength.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
