Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, specifically to an internally expanded pipeline protection cover. Background Technology

[0002] Guy wires installed on 10kV and below power distribution lines are for stabilizing towers; these guy wires balance the tension in all directions of the tower, preventing it from bending or tilting. These line tower guy wires are often made of multi-strand galvanized iron wire or steel strand, and typically form an angle of 30° to 60° with the ground. Consequently, small animals can easily climb over these guy wires onto the operating platforms of the electrical equipment, posing a safety hazard to the normal operation of the power equipment.

[0003] Traditional pipeline protection devices, such as rigid metal sleeves or plastic sheaths, have many drawbacks:

[0004] Poor adaptability: Traditional devices are usually custom-designed and can only be adapted to pipelines of a specific diameter. When the pipeline diameter changes, different specifications of protection devices need to be replaced, increasing costs and installation difficulty.

[0005] Installation is cumbersome: Traditional installations often require dismantling pipelines or damaging surrounding structures before the protective device can be installed. For example, for fixed pipelines, the power supply or fluid must be disconnected, and the connectors must be removed, making the process complex and time-consuming.

[0006] To address the aforementioned problems, this invention proposes an internally expanded pipeline protection cover. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides an internally expanded pipeline protection cover, which solves the problems of poor adaptability and cumbersome installation of traditional protection devices.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an internally expanded pipeline protection cover, comprising:

[0009] The protective cover is designed with a cone-shaped structure.

[0010] Multiple expansion rings are arranged with their diameters increasing sequentially from the inside out. The multiple expansion rings are concentrically arranged with the protective cover, and an annular groove is provided between two adjacent expansion rings. A connecting part for connecting two adjacent expansion rings is provided in the annular groove.

[0011] The mounting hole is formed by the innermost expansion ring. The protective cover is fitted onto the outside of the pipeline through the mounting hole and is used to protect and shield the pipeline. When the diameter of the pipeline is larger than the mounting hole, the connection part of the expansion ring is trimmed until a mounting hole that matches the diameter of the pipeline can be formed.

[0012] The cut is made on the outside of the protective cover and runs through multiple expansion rings. The protective cover can be separated from the multiple expansion rings through the cut. At this time, the protective cover can be fitted onto the outside of the pipeline using the trimmed mounting holes.

[0013] Preferably, the outer edge of the protective cover is provided with a surrounding plate, and the protective cover and the surrounding plate are subjected to an arc transition treatment.

[0014] Preferably, there are multiple connecting parts between two adjacent expansion rings, and the multiple connecting parts are distributed in a circumferential array.

[0015] Preferably, the inner wall surfaces of the plurality of expanding rings are all configured as rough surfaces.

[0016] Preferably, one end of the slit penetrates the protective cover, and a circular groove is provided at the opening on the other side of the slit. The circular groove allows the protective cover to be pulled along the slit to both sides to elastically deform, expanding the slit to accommodate the pipeline. After the pipeline enters the mounting hole, the protective cover returns to its original position.

[0017] Preferably, two connectors are symmetrically arranged on the inner wall of the protective cover with slits, and both connectors have through holes.

[0018] Preferably, the two connecting holes can be connected by expansion screws.

[0019] This utility model discloses an internally expanded pipeline protection cover, which has the following beneficial effects:

[0020] 1. Before installation, if the pipe diameter is larger than the mounting hole, the connection part of the expansion ring is trimmed to create a mounting hole that matches the pipe diameter. The diameter of the mounting hole is adjustable to cover common pipe specifications. The slit design allows for online installation without stopping the machine or disassembling the pipe. Operators can pry the protective cover apart from the multiple expansion rings using the slit. The trimmed mounting hole allows the protective cover to be fitted over the pipe. After being released, the protective cover automatically returns to its original position, wrapping around the pipe, thus preventing small animals from climbing on it.

[0021] 2. This internally expanded pipeline protective cover features a cone-shaped structure to disperse external impact forces and reduce the risk of localized stress concentration. The surrounding panel and the cover body have a rounded transition to prevent foreign objects from entering from the edges, while also enhancing structural strength. The inner wall of the expansion ring has a roughened surface to increase friction with the outer wall of the pipeline, preventing slippage and improving protective stability.

[0028] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0029] This utility model discloses an internally expanded pipeline protection cover.

[0030] According to the appendix Figure 1-4 As shown, it includes:

[0031] The protective cover 1 is designed with a cone-shaped structure;

[0032] Multiple expansion rings 2 are arranged with their diameters increasing sequentially from the inside out. The multiple expansion rings 2 are concentrically arranged with the protective cover 1, and an annular groove 21 is provided between two adjacent expansion rings 2. A connecting part 22 for connecting two adjacent expansion rings 2 is provided in the annular groove 21.

[0033] The mounting hole 3 is formed by the innermost expanding ring 2. The protective cover 1 is fitted onto the outside of the pipeline through the mounting hole 3, and the protective cover 1 is used to protect and shield the pipeline. When the diameter of the pipeline is larger than the mounting hole 3, the connecting part 22 connecting the expanding ring 2 is trimmed until a mounting hole 3 that matches the diameter of the pipeline can be formed.

[0034] The cut 4 is located on the outside of the protective cover 1 and extends through multiple expansion rings 2. The protective cover 1 can be separated from the multiple expansion rings 2 through the cut 4. At this time, the protective cover 1 can be fitted onto the outside of the pipeline using the trimmed mounting hole 3.

[0035] Before installation, if the diameter of the pipeline is larger than the mounting hole 3, the connecting part 22 of the expansion ring 2 is trimmed until a mounting hole 3 that matches the pipeline diameter is formed. The diameter of the mounting hole 3 is adjustable to cover common pipeline specifications. The design of the slit 4 supports online installation without stopping the machine or disassembling the pipeline. The operator can pry the protective cover 1 from the multiple expansion rings 2 through the slit 4. At this time, the protective cover 1 can be fitted onto the outside of the pipeline using the trimmed mounting hole 3. After loosening, the protective cover 1 automatically resets and wraps around the pipeline, thus preventing small animals from climbing.

[0036] Furthermore, a surrounding plate 11 is provided on the outer edge of the protective cover 1, and the protective cover 1 and the surrounding plate 11 are subject to a rounded transition.

[0037] Furthermore, multiple connecting portions 22 are provided between two adjacent diameter-expanding rings 2, and the multiple connecting portions 22 are distributed in a circumferential array.

[0038] Furthermore, the inner wall surfaces of the multiple expansion rings 2 are all set as rough surfaces.

[0039] The protective cover 1 is designed with a cone-shaped structure to disperse external impact forces and reduce the risk of localized stress concentration. The surrounding plate 11 transitions to the protective cover 1 with an arc to prevent foreign objects from entering from the edge, while also enhancing structural strength. The inner wall of the expansion ring 2 has a rough surface to increase friction with the outer wall of the pipeline, prevent slippage, and improve protective stability.

[0040] Specifically disclosed, one end of the slit 4 penetrates the protective cover 1, and a circular groove 41 is provided at the groove opening on the other side of the slit 4. The circular groove 41 can be used to pull the protective cover 1 to elastically deform along the slit 4 to both sides, expanding the slit 4 to accommodate the pipeline. After the pipeline enters the mounting hole 3, the protective cover 1 is reset.

[0041] Preferably, two connectors 42 are symmetrically arranged on the inner wall of the protective cover 1 with a slit 4, and both connectors 42 are provided with through connection holes 43.

[0042] Furthermore, the two connecting holes 43 can be connected by expansion screws.

[0043] After measuring the pipeline diameter, if the pipeline diameter is larger than the initial mounting hole 3, use a tool to trim the connection portion 22 of the innermost expansion ring 2. For example, for a DN150 pipeline, trim the connection portion 22 to the target diameter to form a suitable hole diameter.

[0044] The operator can pry the protective cover 1 apart from the multiple expansion rings 2 by cutting the slit 4. At this time, the protective cover 1 can be put on the outside of the pipeline by using the trimmed mounting hole 3. The protective cover 1 can be put into the pipeline. After loosening, the protective cover 1 will automatically reset and wrap around the pipeline.

[0045] After the pipeline enters the mounting hole 3, the expansion screw is passed through the connecting holes 43 of the two symmetrically arranged connectors 42. Tighten the nuts to lock the expansion screws into the protective cover 1, preventing the protective cover 1 from springing back or shifting due to external force or vibration, and ensuring long-term protective stability.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
