[0036] like Figure 1 - Figure 2 and Figure 4 As shown in the figure, this embodiment provides a corrosion-resistant concrete drainage pipe suitable for water conservancy projects. This corrosion-resistant concrete drainage pipe suitable for water conservancy projects includes a concrete pipe 1, one end of which is provided with a boss 101, and a fixing mechanism 3 is provided inside the boss 101. Two concentric convex rings 7 are provided at the end of the concrete pipe 1 away from the boss 101. A corrosion-resistant pipe 2 is slidably installed inside the concrete pipe 1. The outer wall of the corrosion-resistant pipe 2 is symmetrically provided with slide rails 6, and one end of the slide rails 6 is connected to a docking mechanism 4. A limiting component 5 is provided inside the slide rails 6. The fixing mechanism 3 includes a first slide rod 302. Several mounting grooves 301 are symmetrically opened inside the boss 101. A sealing groove 307 adapted to the convex rings 7 is opened at the end of the boss 101 away from the concrete pipe 1, and the sealing grooves 307 are located on both sides of the mounting grooves 301. A first slider 303 is symmetrically sleeved on the outer wall of the first slide rod 302.

[0037] In this example, the fixing mechanism 3 also includes a connecting block 305, which is symmetrically arranged in the mounting groove 301 on the side away from the concrete pipe 1. One end of the connecting block 305 is fixedly connected to the first slider 303. A first spring 304 is symmetrically sleeved on the outer side of the first slide rod 302, and the first spring 304 is located on the opposite outer side of the first slider 303. The other end of the connecting block 305 is fixedly connected to a locking block 306, and the opposite outer end of the locking block 306 is located in the sealing groove 307. The inner sidewalls of the two protruding rings 7 are each provided with a locking block 306. The 06-adaptive slot 308, through the setting of the fixing mechanism 3, allows for convenient and quick assembly and connection between two drainage pipes. Simply insert the protruding ring 7 at one end of one drainage pipe into the sealing groove 307 opened on the protrusion 101 of the other drainage pipe, causing it to press the locking block 306 to move. When the protruding ring 7 is fully inserted into the sealing groove 307, the locking block 306 will reset and insert into the slot 308 to restrict and fix the protruding ring 7, thereby realizing quick assembly between two concrete pipes 1 and improving the work efficiency of the staff.

[0038] In this example, the mounting groove 301 is convex, the clamping block 306 has a trapezoidal cross section, and a sealing layer is provided between the sealing groove 307 and the convex ring 7 so that one end of the convex ring 7 can press against the inclined surface on the clamping block 306, thereby allowing the clamping block 306 to move into the mounting groove 301. The sealing layer can improve the sealing between the connected pipes.

[0039] like Figure 2 , Figure 3 and Figure 6 As shown in the example, the docking mechanism 4 includes a second slide rod 403. A reset cavity 402 is symmetrically provided inside the slide rail 6. The second slide rod 403 is fixedly installed inside the reset cavity 402. A second slider 405 and a second spring 404 are sleeved on the outer wall of the second slide rod 403, with the second spring 404 located on the opposite outer sides of the two second slide rods 403. A stop block 406 is fixedly connected to one end of the second slider 405. A docking groove 401 is formed at one end of the slide rail 6 between the two reset cavities 402. One end of 405 extends into the docking groove 401. The end of the slide rail 6 away from the docking groove 401 is connected to a support column 408. The end of the support column 408 away from the slide rail 6 is connected to a mating joint 407 that is compatible with the stop block 406. Through the setting of the docking mechanism 4, the corrosion-resistant pipe 2 installed inside the concrete pipe 1 can be easily and quickly spliced ​​to form a whole. This makes it less likely to slide due to the large impact force of water flow during subsequent use, thus affecting the protection of the concrete pipe 1.

[0040] In this example, the top view of the connector 407 is an isosceles trapezoid, the cross-section of the second slider 405 is a right trapezoid, and the stop 406 is parallel to the upper inclined surface of the stop 406 so that the connector 407 can squeeze and push the stop 406, which facilitates the docking connection between the two corrosion-resistant pipes 2.

[0041] like Figure 2 and Figure 5 As shown, the limiting component 5 includes a transmission rod 501, which is movably installed inside the slide rail 6. One end of the transmission rod 501 is located inside the docking groove 401. Several extrusion grooves 506 are provided on the bottom side of the transmission rod 501. Insert rods 502 are provided in the extrusion grooves 506. A magnetic suction groove 504 is provided inside the slide rail 6 below the extrusion grooves 506. The lower end of the insert rod 502 extends through the magnetic suction groove 504 to the outside of the slide rail 6. A magnetic ring 503 is sleeved on the outside of the insert rod 502 inside the magnetic suction groove 504. The inner wall of the concrete pipe 1 has slots 505 that are adapted to the insert rod 502. Through the setting of the limiting component 5, it can be linked with the docking mechanism 4, so that when the two corrosion-resistant pipes 2 are spliced, the mechanism is triggered, thereby driving the insert rod 502 to be inserted into the corresponding slot 505, thereby limiting and fixing the slide rail 6, improving the connection and fixing effect between the corrosion-resistant pipe 2 and the concrete pipe 1, and enabling the two spliced ​​pipes to be reconnected and limited.

[0042] In this example, the inner wall of the concrete pipe 1 is symmetrically provided with rail grooves 8 that are adapted to the slide rail 6. The slot 505 is located on the inner wall of the rail groove 8 away from the corrosion-resistant pipe 2. The magnetic ring 503 is attached to the side wall of the magnetic suction groove 504 near the extrusion groove 506. The upper end of the insertion rod 502 is provided with an inclined surface so that the magnetic ring 503 can be attracted to the inner side wall of the magnetic suction groove 504 to fix the insertion rod 502.

[0043] In use, when two concrete pipes 1 need to be spliced, the protruding ring 7 connected to one end of one concrete pipe 1 can be inserted into the sealing groove 307 opened on the boss 101 connected to one end of the other concrete pipe 1 to achieve the initial splicing of the two. At the same time, as the protruding ring 7 is gradually inserted into the sealing groove 307, one end of the protruding ring 7 will squeeze and push the inclined end of the locking block 306, thereby pushing the locking block 306 to drive the connecting block 305 and the first slider 303 to move inward in a relatively inward direction. At the same time, the first slider 303 slides on the first slide rod 302 and stretches the second spring 404 once, until one end of the locking block 306 is completely inserted. After the convex ring 7 is fully moved to one side, when the convex ring 7 is fully inserted into the sealing groove 307, the locking block 306 will return to its original position under the elastic force of the second spring 404, thus inserting into the locking groove 308 opened in the convex ring 7 to restrict and fix it, thereby completing the quick assembly between the two concrete pipes 1. It is convenient to use and improves the splicing efficiency. Afterwards, the corrosion-resistant pipe 2 can be installed inside the concrete pipe 1, and the slide rail 6 can be slid into the corresponding rail groove 8. The slide rail 6 is moved to the position between the two pipes. When it is necessary to assemble and splice the two corrosion-resistant pipes 2, the butt joint 407 provided at one end of one corrosion-resistant pipe 2 is inserted into the other corrosion-resistant pipe 2. Within the mating groove 401 opened on the slide rail 6 connected to pipe 2, the connector 407 presses against the side blocks 406, causing the second slider 405 to slide along the second slide rod 403. Simultaneously, the second slider 405 presses against the second spring 404 on one side. When the connector 407 moves to the side of the second slider 405 away from the opening of the mating groove 401, the second slider 405 will return to its original position under the elastic force of the second spring 404, thus limiting and fixing the connector 407. At this time, the opposite inner ends of the two corrosion-resistant pipes 2 are exactly touching each other, thus completing the splicing between the two corrosion-resistant pipes 2, making them a whole, and thus not easily affected by water flow. The impact causes slippage, exposing the inner wall of the concrete pipe 1, which leads to corrosion. As the connector 407 gradually presses and moves to the side of the stop block 406, the connector 407 pushes the transmission rod 501 on one side, causing the extrusion groove 506 on the transmission rod 501 to press and push the insertion rod 502, which in turn drives the magnetic ring 503 to move downward. This allows the lower end of the insertion rod 502 to be inserted into the slot 505 opened in the rail groove 8, thereby restricting and fixing the position of the corrosion-resistant pipe 2, connecting it to the concrete pipe 1, and limiting and fixing the concrete pipes 1 on both sides, improving the connection effect between the two, making it convenient to use and more practical.

[0044] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
