Description

Technical Field

[0001] This invention relates to the field of power system equipment technology, specifically to a self-healing device for a composite insulating sheath on a cement pole with a structural curing agent. Background Technology

[0002] In power sector operations, transmission lines are often located in mountainous or forested areas, making them difficult for vehicles to access. Traditional methods for replacing aging and damaged concrete poles require manual labor, such as dragging, carrying, or using winches to pull the poles, which can weigh 500-1000 catties, along mountain roads. This is time-consuming, labor-intensive, and poses safety risks. Furthermore, traditional replacement methods require power outages, severely disrupting users' lives and livelihoods. Therefore, there is an urgent need for a lightweight, live-line-ready, and power-off-interruption-free concrete pole repair device. Summary of the Invention

[0003] The purpose of this invention is to provide a self-healing device for composite insulating sheaths of cement poles with structural curing agents, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a self-repairing device for a composite insulating sheath of a cement pole with a structural curing agent, comprising:

[0005] Cement utility poles;

[0006] An FRP (fiberglass reinforced plastic) reinforcing ring tube is sleeved on the outside of the cement pole, and the FRP reinforcing ring tube is concentrically arranged with the cement pole;

[0007] The FRP glass fiber reinforced ring tube has a connection structure at both ends. The connection structure includes a connecting tooth and a connecting tooth that cooperate with each other. The connecting tooth and the connecting tooth are fastened by a mortise and tenon structure, and structural adhesive is filled at the tooth opening to achieve a seamless connection.

[0008] The FRP glass fiber reinforced ring tube is internally embedded with a glue injection main tube and a glue injection branch tube. The glue injection branch tube is provided with a glue outlet hole, which is connected to the reserved repair space.

[0009] The glue injection pressure device is connected to the glue injection main tube through the glue injection guide tube. The glue injection guide tube is equipped with a one-way valve for pressurizing and injecting repair fluid into the reserved repair space.

[0010] Preferably, the FRP glass fiber reinforced ring tube has a frosted texture and is manufactured using a centrifugal oxygen extraction process to form a high-density composite material structure.

[0011] Preferably, the connecting teeth form a reverse pressing and fastening structure, and the mortise and tenon structure works together with the Class A structural adhesive to achieve a circumferential seal for reinforcing the annular tube.

[0012] Preferably, the glue injection branch pipes are distributed at intervals along the axial direction of the FRP glass fiber reinforced ring pipe, and each glue injection branch pipe has a glue outlet hole with a glue outlet guide groove, which guides the repair fluid to be squeezed into the damaged gap of the cement pole.

[0013] Compared with existing technologies, the beneficial effects of this invention are as follows: The self-repairing device for the composite insulating sheath of cement poles with structural curing agent is lightweight and convenient: using FRP glass fiber composite material, its weight is far lower than that of traditional cement poles, making it easy to carry uphill manually and reducing construction difficulty; It allows for power-off-free repair: without disassembling the old pole, the sheath is directly applied and the repair fluid is injected, enabling live-line work and avoiding the impact of power outages; It has a self-repair function: through a pressurized glue injection system and a multi-point glue dispensing design, the repair fluid can automatically fill the damaged gaps of the pole, improving repair efficiency; It has structural stability: the mortise and tenon joint combined with Class A structural adhesive ensures that the sheath and the pole are tightly fixed, extending the pole's service life to twice that of a new pole.

[0025] 1 cement pole;

[0026] An FRP glass fiber reinforced ring tube 2 is sleeved on the outside of the cement pole 1, and the FRP glass fiber reinforced ring tube 2 is concentrically set with the cement pole 1;

[0027] The FRP glass fiber reinforced ring tube 2 has a connection structure at both ends. The connection structure includes a connecting tooth 5-1 and a connecting tooth 5-2 that cooperate with each other. The connecting tooth 5-1 and the connecting tooth 5-2 are fastened by a mortise and tenon structure, and structural adhesive 6 is filled at the tooth opening to achieve a seamless connection.

[0028] The FRP glass fiber reinforced ring tube 2 is internally embedded with a glue injection main tube 8 and a glue injection branch tube 9. The glue injection branch tube 9 is provided with a glue outlet hole 10, which is connected to the reserved repair space.

[0029] The glue injection pressure device 11 is connected to the glue injection main pipe 8 through the glue injection guide pipe 13. The glue injection guide pipe 13 is equipped with a one-way valve 12 for pressurizing and injecting repair fluid into the reserved repair space.

[0030] In this example, the FRP glass fiber reinforced ring tube 2 has a frosted texture and is made into a high-density composite material structure through a centrifugal oxygen extraction process.

[0031] In this example, connecting tooth 5-1 and connecting tooth 5-2 form a reverse pressing and fastening structure. The mortise and tenon structure and Class A structural adhesive 6 work together to achieve a circumferential seal for reinforcing the annular tube 2.

[0032] In this example, the glue injection branch pipes 9 are distributed at intervals along the axial direction of the FRP glass fiber reinforced ring pipe 2, and each glue injection branch pipe 9 has a glue outlet hole 10 with a glue outlet guide groove 9-1, which guides the repair fluid to be squeezed into the damaged gap of the cement pole 1.

[0033] Working principle: When using the self-repairing device of composite insulation sheath with structural curing agent for cement poles, install FRP glass fiber reinforcing ring tube 2: put the reinforcing ring tube 2 on the damaged part of cement pole 1, and connect it through the mortise and tenon structure of connecting teeth 5-1 and 5-2. Apply Class A structural adhesive 6 to the teeth to form a reverse top pressure fastening to ensure a seamless seal.

[0035] Pressurized glue injection: Start the glue injection pressurizer 11. The repair fluid enters the glue injection main pipe 8 through the glue injection guide pipe 13 and the one-way valve 12, and then flows to the glue injection branch pipe 9. It is squeezed into the damaged gap of the pole through the glue outlet guide groove 9-1 of the glue outlet hole 10 to achieve automatic repair.
