Description

Technical Field

[0001] This utility model relates to the field of pipeline connection, specifically a water conservancy pipeline connection device. Background Technology

[0002] Water conservancy projects are engineering projects built to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. They include flood control, drainage, irrigation, power generation, water supply, reclamation, soil and water conservation, resettlement, and water resource protection projects. They are also called water projects. The construction of water conservancy projects is usually based on the laying of pipelines, among which the connection of pipelines is crucial.

[0003] However, since most pipe connections currently involve directly fitting a sleeve onto the outer end of the pipe, water leakage at the joint is prone to occur during connection. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a water conservancy pipeline connection device, which solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution: a water conservancy pipeline connection device, including a pipe joint, wherein splicing pipes are provided on the inner sides of both ends of the pipe joint, and a joint gasket is installed on the outer side of the splicing pipes. The pipe joint includes: an outer sleeve and an inner joint mechanism. The inner joint mechanism is provided with two embedded tubes inside, and anti-detachment washers are installed on the opposite ends of the two embedded tubes. A corrugated connecting pipe is connected between the two anti-detachment washers. A joint screw is installed inside the two anti-detachment washers. The two ends of the outer sleeve are provided with installation through holes on the outer side of the joint screws, and installation nuts are sleeved on the outer side of the installation through holes.

[0006] As a further improvement of this utility model: the outer array of the anti-detachment washer is provided with a limiting groove, and the inner side wall of the outer sleeve is equipped with a limiting guide block corresponding to the inner side of the limiting groove.

[0007] As a further improvement of this utility model, the inner tube has a water guide oblique opening on the inner side of the end away from the corrugated connecting pipe.

[0008] As a further improvement of this utility model: the outer diameter of the inner tube matches the inner diameter of the spliced ​​pipe, and a sealing gasket is installed between the spliced ​​pipe and the outer tube.

[0009] As a further embodiment of this utility model: the corrugated connecting pipe is fixedly connected to the anti-detachment washer, and the connector screw is movably connected to the anti-detachment washer.

[0010] As a further improvement of this utility model, the limiting guide block slides with the limiting groove.

[0011] As a further embodiment of this utility model: the joint gasket is fixedly connected to the spliced ​​pipe, and the mounting nut is engaged and rotatably connected to the joint screw.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By applying torque to the mounting nut and rotating the connector screw, the two embedded tubes are pulled into the spliced ​​pipe. When the two embedded tubes move and stretch, the corrugated connecting pipe inside is stretched and deformed. Thus, the internal connector mechanism inside the spliced ​​pipe forms a connected pipe, reducing the possibility of water leakage.

[0014] Installing a sealing gasket between the outer jacket and the splicing pipe can achieve double protection and prevent internal water leakage. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1-5 As shown, this embodiment provides a water conservancy pipeline connection device, including a pipe joint 1. Splicing pipes 2 are provided on the inner sides of both ends of the pipe joint 1, and joint gaskets 3 are installed on the outer sides of the splicing pipes 2. The joint gaskets 3 are fixedly connected to the splicing pipes 2. The pipe joint 1 includes an outer sleeve 101 and an inner joint mechanism 102. A sealing gasket is installed between the splicing pipe 2 and the outer sleeve 101. Two embedded tubes 103 are provided inside the inner joint mechanism 102, and the outer diameter of the embedded tubes 103 matches the inner diameter of the splicing pipes 2. Anti-detachment washers 107 are installed at opposite ends of the two inner tubes 103. Corrugated connecting pipes 104 are connected between the two anti-detachment washers 107. Corrugated connecting pipes 104 are fixedly connected to anti-detachment washers 107. Connector screws 105 are installed inside the two anti-detachment washers 107. Connector screws 105 are movably connected to anti-detachment washers 107. The two ends of the outer tube 101 are provided with mounting through holes 106 outside the connector screws 105. Mounting nuts 4 are sleeved on the outside of the mounting through holes 106. Mounting nuts 4 are engaged and rotatably connected to connector screws 105.

[0023] like Figure 2-3 As shown, in this embodiment, the outer array of the anti-detachment washer 107 has a limiting groove 108, and the inner side wall of the outer sleeve 101 is equipped with a limiting guide block 110 corresponding to the inner side of the limiting groove 108. The limiting guide block 110 slides with the limiting groove 108, and the inner tube 103 has a water guide oblique opening 109 on the inner side of the end away from the corrugated connecting pipe 104.

[0024] The working principle of this utility model is as follows: During use, the pipe joint 1 is aligned with the joint positions of the two spliced ​​pipes 2, and the sealing gaskets are aligned with the joint positions of the outer sleeve 101 and the spliced ​​pipes 2. The joint screw 105 extends from the mounting through hole 106 on the outer sleeve 101 and aligns with the hole in the joint gasket 3. The mounting nut 4 is then fitted over the outer side of the joint screw 105. By applying torque to the mounting nut 4 and rotating the joint screw 105, the two inner tubes 103 are aligned with the spliced ​​pipes 2. When the pipe 2 is pulled inside, the limiting groove 108 on the anti-detachment washer 107 is guided to slide under the action of the limiting guide block 110 inside the outer sleeve 101. When the two inner tubes 103 move and stretch as a whole, the corrugated connecting pipe 104 inside is stretched and deformed as a whole. The water guide oblique opening 109 opened on the inner side of the end of the inner tube 103 can reduce the resistance of water impact when guiding water and reduce water seepage from the connection gap between the inner tube 103 and the splicing pipe 2. At the same time, the sealing washer installed between the outer sleeve 101 and the splicing pipe 2 can achieve the purpose of double protection and prevent the internal water from seeping out.
