Description

Technical Field

[0001] This utility model belongs to the field of water conservancy engineering technology, specifically a protective cover for water conservancy engineering pipelines. Background Technology

[0002] Water conservancy projects refer to projects constructed to eliminate water hazards and develop and utilize water resources. Water conservancy projects typically require the laying of a large number of water pipelines. However, multiple pipelines are usually connected by welding or flanges, which makes the stability between two connected pipelines poor. Therefore, it is usually necessary to protect the connection points.

[0003] However, most existing protection methods involve directly burying the pipes in soil. This method allows moisture in the soil to erode the pipe connections, reducing their lifespan. Furthermore, existing protective devices simply connect the pipes, resulting in low hardness at the connection point and poor protection. To address these issues, this invention designs a protective cover for water conservancy engineering pipes. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a protective cover for water conservancy engineering pipelines, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a protective cover for a water conservancy project pipeline, comprising an outer upper pipe, an outer lower pipe at the bottom of the outer upper pipe, an outer upper pipe rotating block fixed at the right end of the outer upper pipe, an outer upper pipe positioning block fixed at the right end of the outer lower pipe, two sets of buckles fixed to the outside of both the outer upper pipe and the outer lower pipe, each set having four buckles, a sealing plate slidably connected inside each buckle, a retaining plate slidably connected to the buckle on the outside of each retaining plate, a moving rod at one end of each retaining plate, and a pipe slidably connected inside the multiple retaining plates, an inner upper pipe inside the outer upper pipe, an inner lower pipe at the bottom of the inner upper pipe, an inner pipe rotating block fixed at the right end of the inner upper pipe, a connecting block fixed at the right end of the inner lower pipe, two sets of inner pipe threaded holes on both the inner upper pipe and the inner lower pipe, a fixing screw engaged inside each inner pipe threaded hole, a fixing arc plate inside each fixing screw, and a fixing arc plate slidably connected to the pipe inside each fixing arc plate.

[0006] Preferably, the upper outer tube positioning block and the upper outer tube rotating block are rotatably connected by the upper outer tube positioning block, and the left ends of both the upper outer tube and the lower outer tube are fixed with an outer tube connecting block, and the outer tube connecting block is slidably connected with an outer tube locking buckle.

[0007] Preferably, the lower outer tube is fixedly connected to the connecting block inside it, the connecting block is rotatably connected to the inner tube rotating block through the inner tube rotating shaft, and the left ends of both the upper inner tube and the lower inner tube are fixed with inner tube connecting plates, and the two inner tube connecting plates are fastened together by inner tube nuts.

[0008] Preferably, two sets of positioning plates are fixed to the outside of the upper outer tube and the lower outer tube. Each positioning plate is slidably connected to the moving rod inside it. A moving rod positioning head is fixed to the inside of each moving rod. A baffle is fixed to the outside of each moving rod. Each baffle is fixedly connected to the locking plate on its outside. A spring is also provided on the outside of each moving rod.

[0009] Preferably, the upper inner tube and the lower inner tube are further provided with two sets of inner tube sliding holes. A positioning rod is slidably connected inside each inner tube sliding hole. Each positioning rod is fixedly connected to the fixing arc plate on its inner side.

The outer ring of each fixing bearing is fixedly connected to the fixing arc plate on its inner side.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This utility model uses a sealing plate to seal the pipe between the upper and lower outer pipes, thereby preventing soil from entering the upper outer pipe, preventing the fixing screw from getting damp, and preventing the pipe from getting damp. This ensures the safety of the fixing screw and positioning rod, thus guaranteeing the safety of the entire equipment, extending its service life, ensuring the safety of the pipe, and guaranteeing the protective effect.

[0012] This invention utilizes a fixed screw that rotates around the threaded hole of the inner tube to move the fixed bearing inward. Simultaneously, the positioning rod prevents the fixed arc plate from rotating, ensuring that the fixed arc plate is aligned with the pipe axis and guaranteeing a clamping effect. This fixes the pipe to the upper and lower inner tubes, preventing breakage at the pipe connection and ensuring effective pipe protection. Furthermore, the fixed screw ensures the fixed arc plate is tightly fitted to the pipe, guaranteeing accurate protection.

[0013] This utility model uses a spring and a moving rod to ensure that the baffle and the buckle are tightly attached, thereby preventing the sealing plate from moving outward and further ensuring the sealing performance of the equipment. This further prevents soil from entering the inner upper and lower pipes, thus protecting the safety of the pipeline and ensuring the protective effect. Attached Figure Description

[0026] Example 2, based on Example 1, combined with... Figure 3 , Figures 6-7The upper outer tube positioning block 105 and the upper outer tube rotating block 104 are rotatably connected via the upper outer tube positioning block 105. Both the upper outer tube 1 and the lower outer tube 103 have an outer tube connecting block 101 fixed to their left ends. The outer tube connecting block 101 is made of alloy material and ensures the sealing of the upper outer tube 1 and the lower outer tube 103. An outer tube locking buckle 102, also made of alloy material, is slidably connected to the outside of the outer tube connecting block 101. The outer tube locking buckle 102 is used to lock the upper outer tube 1 and the lower outer tube 103. The lower outer tube 103 is fixedly connected to the connecting block 502 inside it, thereby allowing the lower inner tube 501 and the lower outer tube 103 to be connected. The connecting block 502 and the inner tube rotating block 504 are rotatably connected via the inner tube rotating shaft 503. An inner tube connecting plate 505 is fixed to the left end of both the upper inner tube 5 and the lower inner tube 501. The inner tube connecting plate 505 is made of alloy material and ensures the sealing of the upper inner tube 5 and the lower inner tube 501. The two inner tube connecting plates 505 are fastened together by an inner tube nut 506. Two sets of positioning plates 404 are also fixed to the outside of the upper outer tube 1 and the lower outer tube 103. The positioning plates 404 are made of alloy material and are used to position the moving rod 403. Each positioning plate 404 is slidably connected to the moving rod 403 inside it. A movable rod positioning head 406 is fixed to the inner side of the rod 403.

A spring 405 is also provided on the outside of each movable rod 403. The spring 405 is elastic, so that the baffle 402 is tightly attached to the buckle 4, thereby preventing the sealing plate 3 from moving. Two sets of inner tube sliding holes 508 are also provided on the inner upper tube 5 and the inner lower tube 501. The sliding hole 508 is used to position the positioning rod 602.

[0027] When using this equipment, the operator opens the outer upper pipe 1 and the inner upper pipe 5 in sequence. The operator then places the entire equipment outside the connection of the pipe 2. Next, the operator rotates the inner upper pipe 5. Due to the action of the inner upper pipe 5, the connecting block 502, and the inner pipe shaft 503, the inner upper pipe 5 and the inner lower pipe 501 are tightly fitted together. The operator then uses two inner pipe nuts 506 to fix the inner upper pipe 5 and the inner lower pipe 501. Finally, the operator rotates multiple fixing screws 601 in sequence, thereby fixing the screws... 601 moves inward along the inner tube threaded hole 507, thereby causing the fixed arc plate 6 to move inward. At this time, due to the function of the positioning rod 602 and the fixed bearing 603, the fixed arc plate 6 is aligned with the axis of the pipe 2, thus ensuring the clamping effect. Further, the operator fine-tunes the multiple fixing screws 601 to make the axis of the pipe 2 aligned with the axis of the inner upper tube 5, thereby placing the pipe 2 at the center of the inner upper tube 5 and the inner lower tube 501. At this time, the multiple fixing screws 601 are in close contact with the pipe 2. 2. The two ends of the connection are fixed to the inner upper tube 5 and the inner lower tube 501 to achieve a protective effect. Further, the operator uses the outer upper tube rotating block 104, the outer upper tube positioning block 105, and the outer tube rotating shaft 106 to make the outer upper tube 1 and the outer lower tube 103 fit tightly together. At this time, the two outer tube connecting blocks 101 are tightly fitted. The operator then pushes the outer tube locking buckle 102 into the outside of the outer tube connecting block 101, thereby fixing the outer upper tube 1 and the outer lower tube 103. The operator then manufactures the device according to the distance between the sealing plate 3 and the outer upper tube 1. Multiple sealing plates 3 are used. The operator further controls the clamping plate 401 to move inwards, and then inserts the sealing plates 3 sequentially into the buckles 4 until the bottom of the sealing plate 3 is in close contact with the outer surface of the pipe 2. At this point, the operator releases the moving rod 403. Due to the action of the spring 405, the baffle 402 moves outwards, causing the clamping plate 401 to move outwards as well. This ensures that the baffle 402 is in close contact with the outer surface of the sealing plate 3, preventing the sealing plates 3 from moving outwards and achieving the protective purpose, thus ensuring the protective effect.

[0028] The working process of this utility model is as follows: When using this device, the operator opens the outer upper pipe 1 and the inner upper pipe 5 in sequence. The operator then places the entire device outside the connection of the pipe 2. The operator then rotates the inner upper pipe 5. At this time, due to the action of the inner upper pipe 5, the connecting block 502, and the inner pipe shaft 503, the inner upper pipe 5 and the inner lower pipe 501 can be tightly attached. The operator then uses two inner pipe nuts 506 to fix the inner upper pipe 5 and the inner lower pipe 501. Finally, the operator rotates multiple fixing screws 601 in sequence, thereby... Multiple fixing screws 601 move inward along the inner tube threaded hole 507, thereby causing the fixing arc plate 6 to move inward. At this time, the positioning rod 602 and the fixing bearing 603 ensure that the fixing arc plate 6 is aligned with the axis of the pipe 2, thus guaranteeing the clamping effect. Further, the operator fine-tunes the multiple fixing screws 601 so that the axis of the pipe 2 is aligned with the axis of the inner upper tube 5, thereby positioning the pipe 2 at the center of the inner upper tube 5 and the inner lower tube 501. At this point, the multiple fixing screws 601 are in close contact with the pipe 2. At this point, both ends of the pipe 2 connection are fixed to the inner upper pipe 5 and the inner lower pipe 501, thereby achieving a protective effect. Further, the operator uses the outer upper pipe rotating block 104, the outer upper pipe positioning block 105, and the outer pipe rotating shaft 106 to make the outer upper pipe 1 and the outer lower pipe 103 fit tightly together. At this time, the two outer pipe connecting blocks 101 are tightly fitted together. The operator then pushes the outer pipe locking buckle 102 into the outside of the outer pipe connecting block 101, thereby fixing the outer upper pipe 1 and the outer lower pipe 103. Further, the operator adjusts the distance between the sealing plate 3 and the outer upper pipe 1... After fabricating multiple sealing plates 3, the operator further controls the clamping plate 401 to move inward. The operator then inserts the sealing plates 3 sequentially into the buckles 4 until the bottom of the sealing plates 3 is in close contact with the outer surface of the pipe 2. At this point, the operator releases the moving rod 403. Due to the action of the spring 405, the baffle 402 moves outward, thereby causing the clamping plate 401 to move outward. This ensures that the baffle 402 is in close contact with the outer surface of the sealing plates 3, preventing the sealing plates 3 from moving outward and thus achieving the purpose of protection and ensuring the protective effect.
