Description

Technical Field

[0001] The utility model relates to the technical field of pipeline protection covers, in particular to a water conservancy project pipeline protection cover. Background Art

[0002] A hydraulic engineering pipe protection cover is a device used to protect the pipe system in hydraulic engineering. It is mainly used to prevent the pipe from being damaged by collision, pressure or other external forces from external objects. Hydraulic engineering pipes usually need to be laid on the ground or underground and are easily affected by vehicles, pedestrians or other engineering construction activities. In order to protect the integrity and safe operation of the pipeline, the pipe protection cover is designed and installed around the pipeline.

[0003] When existing water conservancy pipelines are in use, they need to be butt-jointed between pipe bodies due to terrain and pipe material reasons. However, most of the butt-jointing methods use flanges and bolts for connection. When the joints of the pipe bodies are hit by external forces, they cannot provide effective protection and may cause the joints to loosen, resulting in leakage of the pipe bodies.

The protective plate will be subjected to impact force and will rotate to a certain extent at the hinged position through the hinged connecting rod, thereby causing the protective plate to drive the resistance block to move in the direction close to the trigger block.

[0009] Preferably, a supporting plate is sleeved on the bottom surface of the rubber protective sleeve, and a mounting ring is fixedly connected to the surface of the supporting plate.

[0010] Preferably, a pull strip is fixedly connected to the surface of the rubber protective sleeve, and a latch tooth is hinged on the top surface of the pull strip. A torsion spring 2 is fixedly connected between the latch tooth and the pull strip. When the rubber protective sleeve is pulled, the pull strip will be driven to move together, and the latch tooth hinged on the surface of the pull strip will contact the limiting tooth and rotate downward, thereby compressing the torsion spring 2.

[0011] Preferably, the mounting ring and the sealing ring are both penetrated by mounting bolts and threadedly connected. When the pipe bodies are butt-jointed and installed, the pipe bodies are passed through the mounting rings and threadedly connected by the mounting bolts.

DETAILED DESCRIPTION

[0023] like Figure 1-Figure 6 As shown, the utility model provides a technical solution: a water conservancy project pipeline protective cover, including a pipe body 1, the number of the pipe body 1 is two groups, and the two groups of pipe bodies 1 are symmetrically arranged, and a protective part 2 is arranged between the two groups of pipe bodies 1, and the protective part 2 includes: a sealing ring 21, a connecting rod 22, a protective plate 23, a torsion spring 1 24, an abutment block 25, a limiting tooth 26, a rubber protective sleeve 27, a trigger block 28, a support plate 29, a mounting ring 210, a pull rod 211, a clamping tooth 212, a torsion spring 213, and a mounting bolt 214.

[0024] The sealing ring 21 is fixedly connected to the flange of the pipe body 1 by means of mounting bolts 214. A connecting rod 22 is hingedly connected to the surface of the sealing ring 21. When the connection of the pipe body 1 is impacted by external force, it will first impact the protective plate 23, and the protective plate 23 will be subjected to the impact force and will rotate to a certain extent at the hinged position through the hinged connecting rod 22. The end of the connecting rod 22 away from the sealing ring 21 is hingedly connected to the protective plate 23. A torsion spring 24 is fixedly connected between the connecting rod 22 and the sealing ring 21. The top surface of the abutment block 25 is fixedly connected to the inner side of the protective plate 23. The protective plate 23 is fixedly connected to the sealing ring 21. The inner side of the plate 23 is fixedly connected with the limit teeth 26, the rubber protective sleeve 27 is penetrated by the tube body 1, and the rubber protective sleeve 27 is sleeved with the tube body 1, and the surface of the rubber protective sleeve 27 is fixedly connected with the trigger block 28. The protective plate 23 will be subjected to the impact force and will rotate to a certain extent at the hinged position through the hinged connecting rod 22, so that the protective plate 23 drives the resistance block 25 to move in the direction close to the trigger block 28, and then the arc surface at the bottom of the resistance block 25 resists the inclined surface of the trigger block 28, so that the trigger block 28 moves in the direction close to the sealing ring 21. The bottom surface of the rubber protective sleeve 27 is sleeved with a support plate 29, and the surface of the support plate 29 is fixedly connected with a mounting ring 210. The surface of the rubber protective sleeve 27 is fixedly connected with a pull rod 211, and the top surface of the pull rod 211 is hinged with a clamping tooth 212. A torsion spring 213 is fixedly connected between the clamping tooth 212 and the pull rod 211. When the rubber protective sleeve 27 is pulled, the pull rod 211 will be driven to move together, and the clamping tooth 212 hinged on the surface of the pull rod 211 will contact the limit tooth 26 and rotate downward, and the torsion spring 213 will be compressed. When the clamping tooth 212 exceeds the limit tooth 26, the compressed torsion spring 213 will bounce the clamping tooth 212 and clamp it with the limit tooth 26. The mounting ring 210 and the sealing ring 21 are both penetrated by the mounting bolt 214 and threadedly connected. When the pipe body 1 is docked and installed with the pipe body 1, the pipe body 1 is passed through the mounting ring 210, and the support plate 29 is sleeved with the rubber protective sleeve 27, and the flange of the pipe body 1 is pushed to be embedded in the sealing ring 21, and it is threadedly connected by the mounting bolt 214. The bottom surface of the abutment block 25 is arc-shaped, the cross section of the trigger block 28 is trapezoidal, and the abutment block 25 is aligned with the trigger block 28. When the trigger block 28 is abutted by the abutment block 25, it will drive the rubber protective sleeve 27 to move toward the sealing ring 21, so that the rubber protective sleeve 27 is tightly plugged. The position of the limiting tooth 26 is aligned with the position of the clamping tooth 212 hinged on the surface of the pull rod 211. When the rubber protective sleeve 27 is pulled, it will drive the pull rod 211 to move together. The clamping tooth 212 hinged on the surface of the pull rod 211 will abut the limiting tooth 26 and rotate downward, and at the same time, the torsion spring 213 will be compressed.

[0025] Based on the above embodiment, when the tube body 1 is butt-jointed and installed with the tube body 1, the tube body 1 is passed through the mounting ring 210, and the support plate 29 is sleeved with the rubber protective sleeve 27, the flange of the tube body 1 is pushed to be embedded in the sealing ring 21, and it is threadedly connected by the mounting bolts 214. When the connection of the tube body 1 is impacted by an external force, it will first impact the protective plate 23, and the protective plate 23 will be subjected to the impact force and will rotate to a certain extent at the hinged position through the hinged connecting rod 22, thereby causing the protective plate 23 to drive the resistance block 25 to move in the direction close to the trigger block 28, thereby causing the arc surface at the bottom end of the resistance block 25 to resist the inclined surface of the trigger block 28, thereby causing the trigger block 28 to approach the sealing ring 21, and the trigger block 28 is in the direction of being resisted by the resistance block. When the rubber protective sleeve 27 is moved in the direction of the sealing ring 21, the rubber protective sleeve 27 is driven to move together, and when the rubber protective sleeve 27 is pulled, the pull rod 211 is driven to move together, and the hinged latch 212 on the surface of the pull rod 211 contacts the limiting tooth 26 and rotates downward, and the torsion spring 213 is compressed. When the latch 212 exceeds the limiting tooth 26, the compressed torsion spring 213 bounces the latch 212 and clamps it with the limiting tooth 26 to prevent the rubber protective sleeve 27 from moving back and loosening. Therefore, once the protective plate 23 is hit, the rubber protective sleeve 27 and the sealing ring 21 are more tightly connected, so as to prevent the connection part of the tube body 1 from leaking due to the impact, and increase the service life of the tube body 1.

[0026] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
