Description

Technical Field

[0001] This utility model relates to the field of pipeline repair technology, specifically to a repair structure for damaged pipelines in air-filled and oil-filled equipment. Background Technology

[0002] A substation is a location in a power system that transforms, concentrates, and distributes electrical energy, including voltage and current. Substations contain numerous electrical devices, such as transformers, circuit breakers, and instrument transformers. During operation, the pipes of these devices may occasionally break for various reasons, leading to oil or gas leaks. In such cases, emergency repairs by maintenance personnel are necessary to maintain the normal operation of the equipment.

[0003] However, existing repair methods for damaged pipes in pneumatic and oil-filled equipment still have some shortcomings and need improvement in some practical functions. For example, when repairing damaged pipes in traditional pneumatic and oil-filled equipment, because the internal environment is pressurized, it is often necessary to first shut off the power and then vent and drain the oil before continuing the repair work. The entire repair process is time-consuming and requires high labor costs, which also reduces the continuous working stability of the pneumatic and oil-filled equipment. In addition, when the damaged part of the pipe in the pneumatic and oil-filled equipment is large, the equipment is often replaced directly instead of repaired. This method requires high economic costs and also wastes resources to some extent. Utility Model Content

[0004] To address the problems mentioned above, the purpose of this utility model is to provide a repair structure for damaged pipelines in air-filled and oil-filled equipment. The damaged pipeline is repaired through a combination of a filling layer, a pressure relief component, a sealing component, and a sealing layer. The pressure relief component allows for continuous pressure relief during the repair process, enabling the repair to be carried out under pressure, effectively improving the repair efficiency of the damaged pipeline, and reducing the various costs required for repairing the damaged pipeline.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A repair structure for a damaged pipeline in an air-filled or oil-filled equipment includes a damaged pipeline. The repair structure includes a filling layer, a pressure relief component, a sealing component, and a sealing layer. The filling layer is filled at the damaged opening of the pipeline. The pressure relief component passes through the filling layer and is fixedly connected to it. One end of the pressure relief component is connected to the interior of the damaged pipeline, and the other end of the pressure relief component is sealed to the sealing component. The sealing layer is fixedly disposed on the outside of the filling layer.

[0007] Furthermore, the pressure relief component has a central through hole at its center, one end of which is connected to the interior of the damaged pipe, and the other end of which is connected to the outside.

[0008] Furthermore, the pressure relief component has an internal thread inside the central through hole, and the sealing component has an external thread on its outer edge. The pressure relief component and the sealing component are connected by the engagement of the internal thread and the external thread.

[0009] Furthermore, a cross-shaped groove is provided on one side of the seal, which is adapted to a screwdriver provided externally.

[0010] Furthermore, the filling layer is composed of a polymeric sealing material.

[0011] Furthermore, the sealing layer is configured as an electrical sealant.

[0012] The beneficial effects of this utility model are as follows:

[0013] (1) The repair structure of this utility model includes a filling layer, a pressure relief component, a sealing component, and a sealing layer. The filling layer is filled and placed at the broken opening of the damaged pipe. The pressure relief component passes through the filling layer and is fixedly connected to it. When the filling layer is used to repair the broken opening of the damaged pipe, the pressure relief component can continuously discharge the gas or oil inside the damaged pipe, so that the damaged pipe can be continuously depressurized during the repair process, thereby realizing the repair work of the damaged pipe in a pressurized environment. When the filling layer fills the broken opening of the damaged pipe, the sealing component is sealed and connected to one end of the pressure relief component to complete the repair work. This effectively simplifies the repair process of the damaged pipe, reduces the time and labor costs required during the repair process, and maintains the continuous stability of the gas and oil filling equipment. In addition, by combining the filling layer, pressure relief component, sealing component, and sealing layer to replace the traditional method of directly replacing the equipment to avoid repair, it can save a certain degree of economic cost and avoid unnecessary waste of resources, which is in line with the principles of green, environmental protection, and energy saving.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] As attached Figure 1-4 As shown in the embodiment of this utility model, a repair structure for a damaged pipeline of an air-filled or oil-filled equipment is provided, including a damaged pipeline 1. The repair structure includes a filling layer 2, a pressure relief component 3, a sealing component 4, and a sealing layer 5. The filling layer 2 is filled and disposed at the damaged opening of the damaged pipeline 1. The pressure relief component 3 passes through the filling layer 2 and is fixedly connected to it. One end of the pressure relief component 3 is connected to the interior of the damaged pipeline 1, and the other end of the pressure relief component 3 is sealed and connected to the sealing component 4. The sealing layer 5 is fixedly disposed on the outside of the filling layer 2.

[0021] Specifically, the pressure relief component 3 can be fixedly bonded to the filling layer 2 using a high-strength two-component epoxy resin adhesive.

[0022] Specifically, the pressure relief component 3 can be set as a cylindrical nut, and the pressure relief component 3 is located at the center of the rupture opening of the damaged pipe 1.

[0023] The pressure relief component 3 of this utility model has a central through hole 301 at its center. One end of the central through hole 301 is connected to the interior of the damaged pipe 1, and the other end of the central through hole 301 is connected to the outside.

[0024] Specifically, the gas or oil inside the damaged pipe 1 is discharged to the outside through the central through hole 301, thereby achieving the pressure relief effect of the damaged pipe 1.

[0025] The pressure relief component 3 of this utility model has an internal thread 3011 inside the middle through hole 301, and an external thread 401 is provided on the outer edge of the sealing component 4. The pressure relief component 3 and the sealing component 4 are connected by a screw thread through the mating of the internal thread 3011 and the external thread 401.

[0026] The sealing element 4 of this utility model has a cross groove 402 on one side, which is adapted to the screwdriver set on the outside.

[0027] Specifically, the operator can insert a screwdriver into the cross groove 402 and twist the seal 4 to seal the seal 4 to one end of the pressure relief component 3.

[0028] The filling layer 2 of this invention is composed of a polymer sealing material.

[0029] Specifically, the main material type of the polymer sealing material is a mixture of modified epoxy resin and high magnetic metal powder, with a curing agent added in proportion. The filling layer 2 has high adhesion, high pressure resistance, corrosion resistance and air impermeability, so as to seal the gas or oil inside the damaged pipe 1 inside it.

[0030] The sealing layer 5 of this invention is set as an electrical sealant.

[0031] Specifically, the electrical sealant has the advantages of aging resistance and good elasticity. By placing the electrical sealant on the outside of the filling layer 2, it can protect the filling layer 2, which is composed of polymer sealing material, from the effects of ultraviolet rays, ozone, etc., thereby effectively preventing the filling layer 2 from cracking and affecting the repair effect. At the same time, after curing, the electrical sealant can provide an extra protective barrier for the leakage location, which can enhance the repair effect.

[0032] In the specific implementation of this utility model, the workers first take various insulation measures, then use tweezers or other fixing tools to horizontally and fix the pressure relief component 3 in the center of the damaged opening of the damaged pipe 1. Next, the filling layer 2 is used to fill the damaged opening of the damaged pipe 1 from the bottom. When the filling layer 2 is about to contact the bottom of the pressure relief component 3, the filling is paused. High-strength two-component epoxy resin is applied to the bottom and sides of the pressure relief component 3, so that the pressure relief component 3 can form a stable bond with the filling layer 2 through the high-strength two-component epoxy resin. Then, the filling layer 2 is continued to be filled from bottom to top at the damaged opening of the damaged pipe 1. When the filling layer 2 is high When the pressure exceeds the pressure relief component 3, the pressure relief component 3 has formed a fixed connection with the filling layer 2. The tweezers or other fixing tools can then be removed to detach them from the pressure relief component 3. The filling layer 2 is then filled until the damaged opening of the damaged pipe 1 is completely filled. After the damaged opening of the damaged pipe 1 is filled with the filling layer 2, the workers screw the sealing component 4 onto one end of the pressure relief component 3. Then, a sealing layer 5 made of electrical sealant is applied to the outside of the filling layer 2. In addition, during the repair process, workers can set up a gas collection tank or oil collection tank on the outside and connect it to the pressure relief component 3 to collect and recover the gas or oil discharged from the pressure relief component 3.

[0033] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
