Technical Field

[0001] The utility model relates to the technical field of plastic - jacketed steel thermal insulation pipes, and particularly relates to a protection device for plastic - jacketed steel thermal insulation pipes. Background Technique

[0002] The plastic - jacketed steel thermal insulation pipe is also called a polyurethane foam thermal insulation pipe or a directly buried polyurethane thermal insulation pipe. It is composed of a working steel pipe for conveying media, a foam insulation layer, and a polyethylene plastic outer protection pipe, which are successively combined outward through equipment.

[0003] After retrieving the Chinese patent "A protection device for a hydrogen - mixed natural gas transmission pipeline", with the publication number "CN215111323U", this patent greatly improves the protection effect of the device on the pipeline through the combined action of a high - strength layer, a stainless - steel layer, a fiberglass layer, a protection sleeve body, a pipeline body, a heat - insulation layer, a rock wool layer, and a rubber - plastic insulation layer, effectively ensuring that the pipeline can be used normally and stably in a complex environment and meeting people's usage requirements. However, when the plastic - jacketed steel thermal insulation pipe is accidentally collided, this device is likely to cause deformation and damage to the plastic - jacketed steel thermal insulation pipe, making it inconvenient to effectively protect the plastic - jacketed steel thermal insulation pipe and reducing the usage effect of the device.

[0004] Therefore, a protection device for plastic - jacketed steel thermal insulation pipes is proposed to solve the above problems. Content of the Utility Model

The support block and the mounting block can buffer and protect the plastic - jacketed steel thermal insulation pipe through the first spring telescopic rods when it is collided.

[0008] Preferably, a plurality of uniformly distributed limiting grooves are formed at the top end of the support block, and the limiting grooves can improve the supporting effect of the support block on the plastic sleeve steel insulation pipe and prevent it from loosening during placement.

[0009] Preferably, one end of the inner wall of the sealing cover is fixedly connected with a partition board, and a sealing gasket is sleeved at one end of the partition board. The partition board can snap the sealing cover into the outer protection pipe, and the sealing gasket improves the heat preservation effect of the plastic sleeve steel insulation pipe.

[0010] Preferably, a sealing ring is fixedly connected to the inner wall of the sealing cover, and the sealing ring is arranged between the sealing cover and the steel pipe to improve the heat preservation and sealing effect of the plastic sleeve steel insulation pipe.

[0011] Preferably, the protection assembly includes a plurality of two fixing blocks that are uniformly distributed and fixedly connected to the inner wall of the outer protection pipe.

[0023] As Figure 2 and Figure 3As shown, the protection mechanism 3 further includes several support blocks 303 that are evenly distributed and slidably connected to the outer wall of the sealing cover 302. The bottom end of the support block 303 is fixedly connected with a mounting block 304. Two first spring telescopic rods 305 are fixedly connected between the mounting block 304 and the sealing cover 302. The top end of the support block 303 is provided with several evenly distributed limiting grooves 306. One end of the inner wall of the sealing cover 302 is fixedly connected with a partition plate 307. One end of the partition plate 307 is sleeved with a sealing gasket 308. A sealing ring 309 is fixedly connected to the inner wall of the sealing cover 302. When protecting the plastic-sheathed steel insulated pipe, the sealing cover 302 is threadedly connected to both ends of the outer protection pipe 2. The diameter of the sealing cover 302 is larger than that of the outer protection pipe 2 and cooperates with the support block 303 to support and protect the plastic-sheathed steel insulated pipe. The sealing ring 309 can improve the sealing effect between the sealing cover 302 and the steel pipe 1.

One end of one of the fixing blocks 3101 is fixedly connected with a limiting plate 3103. The bottom end of the limiting plate 3103 is fixedly connected with a protection pad 3104. When protecting the plastic-sheathed steel insulated pipe, the two fixing blocks 3101 can buffer and protect the pressure received by the plastic-sheathed steel insulated pipe through the second spring telescopic rods 3102. The limiting plate 3103 and the protection pad 3104 cooperate to protect the surface of the steel pipe 1 when the fixing block 3101 supports the outer protection pipe 2, and can support and protect the plastic-sheathed steel insulated pipe to improve the strength of the plastic-sheathed steel insulated pipe.
