Description

Technical Field

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

[0002] In the field of modern water conservancy engineering, water pipelines serve as a crucial carrier for water resource transportation, and the reliability and convenience of their connection methods directly impact project benefits. Currently, the common connection methods for water pipelines in water conservancy projects are welding or flange bolt connections. Welded connections utilize high-temperature melting of the pipe interfaces to form an integrated structure, while flange bolt connections achieve a tight connection between pipes through bolt tightening and sealing gaskets. Both methods effectively ensure the sealing and stability of water pipelines during operation, meeting the basic requirements for leak prevention and water pressure resistance during water transportation.

[0003] However, the aforementioned traditional connection methods have revealed significant shortcomings in the later maintenance and replacement of water conservancy pipelines. Welded connections permanently fix the pipe joints, resulting in extremely low maintenance efficiency when faced with a large number of pipe joints in large-scale water conservancy projects. Furthermore, the bolts are prone to rusting and stripping due to long-term water flow impact and corrosion, further increasing the difficulty of disassembly. This leads to time-consuming and costly maintenance and replacement operations for water conservancy pipelines, seriously affecting the operation and maintenance efficiency and sustainability of water conservancy projects. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a water conservancy pipeline device for water conservancy projects, which can effectively solve the problem of cumbersome operation in the later maintenance and replacement of water conservancy pipelines by the existing connection method.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides a water conservancy pipeline device for water conservancy projects, including a first water conservancy pipeline and a second water conservancy pipeline distributed from left to right. The first water conservancy pipeline has an installation groove at one end near the second water conservancy pipeline. The second water conservancy pipeline has an annular installation plate whose shape is adapted to the installation groove at one end near the first water conservancy pipeline. Two positioning grooves are symmetrically opened on the outer side of the annular installation plate. Two limiting components that cooperate with the positioning grooves are provided in the first water conservancy pipeline. An auxiliary component is also provided in the installation groove.

[0007] The limiting component includes two sliding cavities symmetrically opened inside the first water conservancy pipeline and communicating with the installation groove. The sliding cavities are slidably connected to positioning blocks. Multiple limiting springs are fixedly connected between the positioning blocks and the sliding cavities. Unlocking rods that pass through the first water conservancy pipeline are fixedly connected to the opposite ends of the two positioning blocks.

[0008] According to the above-mentioned water conservancy pipeline device for water conservancy projects, the auxiliary component includes a top plate that is slidably connected to the mounting groove, and a plurality of compression springs are fixedly connected in a ring array between the top plate and the mounting groove.

[0009] According to the above-mentioned water conservancy pipeline device for water conservancy projects, both of the positioning blocks have beveled edges at one end near the annular mounting plate.

[0010] According to the above-mentioned water conservancy pipeline device for water conservancy projects, when the annular mounting plate is fully inserted into the mounting groove, the positioning block corresponds to the vertical position of the positioning groove.

[0011] According to the above-mentioned water conservancy pipeline device for water conservancy projects, when the positioning block and the positioning groove are engaged, the compression spring is in a compressed state, and the compression spring is never in a state of extreme compression.

[0012] According to the above-mentioned water conservancy pipeline device for water conservancy projects, a sealing gasket is fixedly bonded to one end of the first water conservancy pipeline near the second water conservancy pipeline, and the sealing gasket is made of non-asbestos fiber rubber.

[0013] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0014] 1. This utility model adopts a positioning block and positioning groove to engage and a disassembly method controlled by an unlocking rod. During later maintenance and pipe replacement, the pipe can be easily separated simply by pulling the unlocking rod, which greatly improves maintenance efficiency. For the numerous pipe interfaces in large-scale water conservancy projects, this simple and convenient connection method has even more obvious advantages, which can effectively shorten maintenance time and reduce maintenance costs.

[0015] 2. This utility model, through the synergistic effect of the limiting component and auxiliary component, the snap-fit ​​cooperation between the positioning block and the positioning groove, and the auxiliary thrust of the compression spring, makes the pipeline connection firm and stable, capable of withstanding water flow pressure, ensuring the reliability of the water conservancy pipeline during operation. It eliminates the need for bolt connections, thus avoiding the problems of bolt rusting or stripping that lead to disassembly difficulties. During the long-term operation of the water conservancy pipeline, it can always maintain good maintainability and replaceability, effectively ensuring the operation and maintenance efficiency and sustainability of water conservancy projects.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] The present invention will be further described below with reference to the embodiments.

[0024] Example: Refer to Figures 1 to 4 A water conservancy pipeline device for water conservancy projects includes a first water conservancy pipeline 1 and a second water conservancy pipeline 2 distributed from left to right. A sealing gasket is fixedly bonded to one end of the first water conservancy pipeline 1 near the second water conservancy pipeline 2. The sealing gasket is made of non-asbestos fiber rubber. The non-asbestos fiber rubber sealing gasket has good flexibility, water resistance and sealing performance. After the water conservancy pipelines are connected, the sealing gasket fills the gap between the connection between the first water conservancy pipeline 1 and the second water conservancy pipeline 2, which can effectively prevent water from seeping out from the pipeline connection, ensure the sealing performance of the water conservancy pipeline during water transportation, avoid water leakage and loss, and ensure the water transportation efficiency of the water conservancy project.

[0025] The first water pipe 1 has an installation groove 11 at one end near the second water pipe 2. The second water pipe 2 has an annular installation plate 21 with a shape that matches the installation groove 11 at one end near the first water pipe 1. Two positioning grooves 22 are symmetrically opened on the outer side of the annular installation plate 21. When the annular installation plate 21 is fully inserted into the installation groove 11, the positioning block 4 corresponds to the vertical position of the positioning groove 22. When performing the pipe connection operation, the annular installation plate 21 of the second water pipe 2 is aligned with the installation groove 11 of the first water pipe 1 and inserted. Since the annular installation plate 21 and the installation groove 11 are shaped to match, the accuracy of the two during the docking process can be guaranteed, which facilitates the subsequent positioning and fixing operation. When the annular installation plate 21 is fully inserted into the installation groove 11, the positioning block 4 and the positioning groove 22 are exactly aligned in the vertical direction. The positioning block 4 is inserted into the positioning groove 22 to realize the pipe connection and fixing.

[0026] The first water conservancy pipeline 1 is equipped with two limiting components that cooperate with the positioning groove 22. Specifically, the limiting components include two sliding cavities 3 symmetrically opened in the first water conservancy pipeline 1 and communicating with the installation groove 11. The sliding cavities 3 are slidably connected to the positioning blocks 4, and multiple limiting springs 5 ​​are fixedly connected between the positioning blocks 4 and the sliding cavities 3. When the annular mounting plate 21 is inserted into the installation groove 11, the outer wall of the annular mounting plate 21 will squeeze the beveled edge of the positioning block 4 near the end of the annular mounting plate 21. Under the action of the squeezing force, the positioning block 4 overcomes the elastic force of the limiting springs 5 ​​and slides along the sliding cavity 3 in a direction away from the installation groove 11, so that the limiting springs 5 ​​are compressed. When the annular mounting plate 21 is fully inserted and the positioning block 4 corresponds to the positioning groove 22, under the action of the restoring elastic force of the limiting springs 5, the positioning block 4 quickly slides towards the installation groove 11 and is locked into the positioning groove 22, thereby restricting the axial movement of the annular mounting plate 21 in the installation groove 11 and realizing the fixed connection between the first water conservancy pipeline 1 and the second water conservancy pipeline 2.

[0027] Each of the two positioning blocks 4 has an unlocking rod 6 that extends out of the first water pipe 1 fixedly connected to one end of each positioning block 4. When unlocking, the two unlocking rods 6 are pulled in opposite directions, which causes the two positioning blocks 4 to disengage from the two positioning slots 22. The first water pipe 1 and the second water pipe 2 can be disassembled by pulling them in opposite directions.

[0028] Both positioning blocks 4 have beveled edges at one end near the annular mounting plate 21. The beveled edges are designed to facilitate the smooth sliding of the positioning blocks 4 when the annular mounting plate 21 is inserted. During the insertion of the annular mounting plate 21, the beveled edges make the contact between the annular mounting plate 21 and the positioning blocks 4 a beveled contact. Compared with a flat contact, this method makes it easier for the positioning blocks 4 to slide due to the pressure, reducing the resistance during insertion, making the pipe connection operation smoother and more convenient, and improving the installation efficiency.

[0029] An auxiliary component 12 is also provided inside the mounting slot 11. Specifically, the auxiliary component 12 includes a top plate 121 that is slidably connected to the mounting slot 11. Multiple compression springs 122 are fixedly connected in a ring array between the top plate 121 and the mounting slot 11. When the positioning block 4 is engaged with the positioning slot 22, the compression springs 122 are in a compressed state, and the compression springs 122 are never in a state of extreme compression. During the process of inserting the annular mounting plate 21 into the mounting slot 11, the annular mounting plate 21 will push the top plate 121 to move, thereby squeezing the compression springs 122. When the positioning block 4 is engaged in the positioning slot 22, the compression springs 122 are continuously compressed. When compressed, the elastic force generated will act on the top plate 121, thereby applying a pushing force to the annular mounting plate 21 in the direction of the positioning block 4. This pushing force can further enhance the locking stability between the positioning block 4 and the positioning groove 22, preventing the positioning block 4 from accidentally coming out of the positioning groove 22 under the action of external forces such as water flow impact, and ensuring the firmness of the connection between the first water pipe 1 and the second water pipe 2. On the other hand, when the two unlocking rods 6 are pulled to disassemble the pipes, the compressed compression spring 122 can push the first water pipe 1 and the second water pipe 2 backwards when the positioning block 4 is separated from the positioning groove 22, which facilitates disassembly.

[0030] The working principle of this utility model is as follows:

[0031] When connecting water conservancy pipelines, first insert the annular mounting plate 21 of the second water conservancy pipeline 2 into the mounting groove 11 of the first water conservancy pipeline 1. During the insertion process, the outer wall of the annular mounting plate 21 presses the beveled edge of the positioning block 4 near one end of the annular mounting plate 21. The positioning block 4 overcomes the elastic force of the limiting spring 5 and slides along the sliding cavity 3 away from the mounting groove 11. The limiting spring 5 is compressed. When the annular mounting plate 21 is fully inserted into the mounting groove 11, the positioning block 4 corresponds vertically to the positioning groove 22. At this time, the limiting spring 5 restores its elastic force and pushes the positioning block 4 to quickly lock into the positioning groove 22, restricting the axial movement of the annular mounting plate 21 in the mounting groove 11, thereby fixing the first water conservancy pipeline 1 and the second water conservancy pipeline 2.

[0032] At the same time, during the process of inserting the annular mounting plate 21 into the mounting groove 11, it will push the top plate 121, causing the compression spring 122 in the mounting groove 11 to be squeezed. After the positioning block 4 is inserted into the positioning groove 22, the compression spring 122 continues to be in a compressed state. The elastic force generated by it applies a pushing force to the annular mounting plate 21 in the direction of the positioning block 4 through the top plate 121, further strengthening the snapping stability between the positioning block 4 and the positioning groove 22, and ensuring the firmness of the pipe connection.

[0033] When it is necessary to disassemble the pipes, pull the two unlocking rods 6 in opposite directions. The unlocking rods 6 will cause the positioning block 4 to disengage from the positioning groove 22. At this time, the compressed spring 122 will push the first water pipe 1 and the second water pipe 2 in opposite directions, which will help the operator to separate the two pipes in opposite directions to complete the disassembly operation.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
