Description

Technical Field

[0001] The invention relates to the technical field of electric power safety, and in particular to a room-temperature applying device for removing dirt from the surface of a composite insulator. Background Art

[0002] At present, the composite post insulator jacket is made of silicone rubber composite insulation material, which is gradually widely used in power equipment due to its good hydrophobicity and anti-pollution flashover. However, as an organic material, silicone rubber composite insulation material is subjected to temperature changes, humidity changes, ultraviolet radiation, wind and rain washing, arc erosion, acid and alkali corrosion, etc. during operation, and aging problems are inevitable. Since the small organic molecules on the surface of silicone rubber have a wrapping effect on dirt, it is not easy to be washed by natural wind and rain. Therefore, after long-term operation, the surface dirt of the composite post insulator gradually increases, and its hydrophobic migration becomes worse. During the annual power outage maintenance of the ultra-high / ultra-high voltage substation, the station-used composite post insulators must be manually decontaminated to improve their external insulation performance. The main methods of manual decontamination are high-pressure water washing and manual wiping. However, since the dirt on the surface of silicone rubber insulation is cross-linked with the migrated silicone oil small molecules after long-term operation, high-pressure water washing can generally only remove surface dust, and the dirt cross-linked inside the composite insulation layer is not easy to remove. Manual wiping is more effective than high-pressure water washing but has lower efficiency. After wiping, the hydrophobicity of the surface of the composite post insulator is destroyed, which is difficult to recover and migrate in a short time, reducing the anti-pollution flashover performance of the composite post insulator. Summary of the invention

[0003] In view of this, the present invention proposes a room temperature application device for removing dirt from the surface of a composite insulator, aiming to solve the problem of increasing the speed of cleaning dirt from the surface of a composite post insulator.

[0004] In one aspect, the present invention provides a room temperature application device for removing dirt from the surface of a composite insulator, comprising: an adhesive tape and an application plate, wherein the adhesive tape is used to adhere to the surface of the composite insulator to remove dirt from the surface of the composite insulator, and the application plate is used to press the adhesive tape to make the adhesive tape closely adhere to the surface of the composite insulator; wherein:

[0005] The adhesive tape comprises a backing material and a decontamination layer, wherein the backing material is connected to one side of the decontamination layer, and the decontamination layer is used to contact the surface of the composite post insulator to remove dirt on the surface of the composite post insulator.

[0006] Furthermore, the adhesive tape further comprises an isolation layer, the isolation layer is bonded to the other side of the decontamination layer, and the isolation layer is used to protect the decontamination layer from being contaminated.

[0007] Furthermore, the adhesive tape is a spiral ring structure.

[0008] Furthermore, the adhesive tape is provided with a breakpoint tearable structure.

[0009] Furthermore, the material used for the decontamination layer includes a polymer material with a strong polar functional group, and the polymer material is a viscous resin made by copolymerization of a variety of polar monomers; the viscous resin is an acrylate copolymer or polyurethane.

[0010] Furthermore, the material used for the decontamination layer also includes a viscosity regulator, a cross-linking agent and an antioxidant, and the viscous resin is mixed with the viscosity regulator, the cross-linking agent and the antioxidant to form the decontamination layer.

[0011] Furthermore, the acrylic ester copolymer or polyurethane, and the viscosity regulator, cross-linking agent and antioxidant are mixed in the following weight parts to form the decontamination layer:

[0012]

[0013] Furthermore, the backing material comprises any one of the following polymer films: polyimide film, polyethylene film, polyvinylidene fluoride film or polytetrafluoroethylene film.

[0014] Furthermore, the application plate comprises an arc-shaped plate, and a plurality of convex points are arranged on the lower side of the arc-shaped plate.

[0015] Furthermore, a handle is provided on the upper side of the arc-shaped plate.

[0016] Compared with the prior art, the beneficial effect of the present invention lies in that the adhesive tape for removing dirt on the surface of the composite post insulator of the present invention supports the decontamination layer by setting a back material, and protects the decontamination layer from being contaminated by an isolation layer. When in use, the decontamination layer is pasted to the dirty part on the surface of the composite post insulator to remove the dirt. The binding force between the decontamination layer and the dirt is greater than the binding force between the dirt and the silicone rubber material on the surface of the composite post insulator. When the decontamination layer is peeled off, the dirt on the surface of the composite post insulator can be brought down, thereby effectively removing the dirt on the surface of the composite post insulator. It can be seen that the present invention only needs to stick the adhesive tape to the dirty part on the surface of the composite post insulator, and then tear off the adhesive tape to complete the dirt removal, which greatly improves the cleaning speed of the dirt on the surface of the composite post insulator.

[0017] Furthermore, the decontamination layer in the present invention is made of polymer material, and after the decontamination layer is pasted on the composite post insulator, according to the principle that the binding force between the polymer material and the dirt is greater than the binding force between the dirt and the silicone rubber material, the dirt components on the surface of the composite post insulator can be taken out at the same time as the tape is peeled off, and the dirt on the surface of the composite post insulator is effectively removed. At the same time, the effective ingredients in the polymer material can partially penetrate into the silicone rubber on the surface of the composite post insulator, playing a role in restoring the surface hydrophobicity of the composite post insulator, so that its surface state can meet the operation requirements of the power system in the shortest time, speed up the work progress, and improve work efficiency.

A handle is provided on the upper side of the arc-shaped plate to facilitate taking and operating the arc-shaped plate.

[0026] See also Figure 2 As shown, the adhesive tape comprises a backing material 1, a decontamination layer 2 and an isolation layer 3, wherein the backing material 1 is connected to one side of the decontamination layer 2, and the isolation layer 3 is bonded to the other side of the decontamination layer 2. The decontamination layer 2 is used to contact the surface of the composite post insulator to remove dirt on the surface of the composite post insulator, and the isolation layer 3 is used to protect the decontamination layer 2.

[0027] Specifically, the backing material 1 and the isolation layer 3 are respectively arranged on the opposite side surfaces of the decontamination layer 2, and the decontamination layer 2 is tightly combined with the backing material 1 by polymerization or bonding. The backing material 1 is used to support and strengthen the decontamination layer 2. The backing material 1 is the coating base of the decontamination layer 2, and has a certain structural strength and a certain elasticity. The decontamination layer 2 is coated and spread on the backing material 1, and the two are tightly bonded. The backing material 1 can undergo corresponding deformation according to the surface shape of the insulator under the action of external force and has a certain strength of flexible supporting material.

[0028] Specifically, the decontamination layer 2 is mainly made of a polymer material with a strong polar functional group, that is, the material used in the decontamination layer 2 includes a polymer material with a strong polar functional group, and the polymer material with a strong polar functional group is the main material of the decontamination layer 2. Specifically, the polymer material is preferably a viscous resin made by copolymerizing a plurality of polar monomers.

[0029] Specifically, the isolation layer 3 is preferably a film with low surface energy, and its function is to ensure that the decontamination layer 2 is not contaminated during storage and transportation.

[0030] Specifically, the above-mentioned tape uses a polymer material as the main material, and the tape is pasted on the composite post insulator. According to the principle that the binding force between the polymer material and dirt is greater than the binding force between dirt and silicone rubber material, the dirt components on the surface of the composite post insulator can be taken out at the same time as the tape is peeled off, and the dirt on the surface 5 of the composite post insulator can be effectively removed. At the same time, the effective components in the polymer material can partially penetrate into the silicone rubber on the surface 5 of the composite post insulator, which plays a role in restoring the surface hydrophobicity of the composite post insulator, so that its surface state can meet the operation requirements of the power system in the shortest time, and speed up the work progress.

[0031] Specifically, the adhesive resin is preferably an acrylic acid ester copolymer or polyurethane.

[0032] Specifically, the material used in the decontamination layer 2 also includes a viscosity regulator, a cross-linking agent and an antioxidant, and the adhesive resin is mixed with the viscosity regulator, the cross-linking agent and the antioxidant to form the decontamination layer 2. Specifically, the decontamination layer 2 is mainly composed of a polymer material with a strong polar functional group, and the main material is a viscous resin made by copolymerization of multiple polar monomers, and the viscous resin is mixed with a viscosity regulator, a cross-linking agent and an antioxidant to form the above-mentioned decontamination layer 2. The decontamination layer 2 can infiltrate and adhere to the dirt particles on the surface of the silicone rubber material of the composite post insulator. When the decontamination layer 2 is peeled off, the dirt can be removed without leaving residual glue on the silicone rubber surface.

[0033] Specifically, the backing material 1 comprises any one of the following polymer films: polyimide, polyethylene, polyvinylidene fluoride or polytetrafluoroethylene, that is, the backing material 1 is preferably a polyimide film, a polyethylene film, a polyvinylidene fluoride film or a polytetrafluoroethylene film.

[0034] Specifically, the thickness of the backing material 1 is less than or equal to 0.5 mm. The thickness of the backing material 1 can be set according to actual conditions.

[0035] Specifically, the isolation layer 3 is a film with low surface energy, and the film with low surface energy includes wax paper, polytetrafluoroethylene film or PET film, that is, the isolation layer 3 can be wax paper, polytetrafluoroethylene film or PET film.

[0036] Specifically, the acrylic ester copolymer or polyurethane, the viscosity regulator, the cross-linking agent and the antioxidant are mixed in the following weight parts to form the decontamination layer 2:

[0037]

[0038] Example 1

[0039] Specifically, 20 parts of acrylate copolymer or polyurethane, 4 parts of viscosity regulator, 2 parts of cross-linking agent and 1 part of antioxidant are put into a reaction kettle, and the above materials are blended to form a decontamination layer 2 after stirring. After the decontamination layer 2 is prepared, it is coated or laminated on the backing material 1, and after the decontamination layer 2 is combined with the backing material 1, the isolation layer 3 is laminated on the decontamination layer 2 to complete the preparation of the tape.

[0040] Example 2

[0041] Specifically, 30 parts of acrylate copolymer or polyurethane, 7 parts of viscosity regulator, 5 parts of cross-linking agent and 3 parts of antioxidant are put into a reaction kettle, and the above materials are blended to form a decontamination layer 2 after stirring. After the decontamination layer 2 is prepared, it is coated or laminated on the backing material 1, and after the decontamination layer 2 is combined with the backing material 1, the isolation layer 3 is laminated on the decontamination layer 2 to complete the preparation of the tape.

[0042] Example 3

[0043] Specifically, 40 parts of an acrylate copolymer or a polyurethane, 10 parts of a viscosity regulator, 8 parts of a cross-linking agent and 5 parts of an antioxidant are put into a reaction kettle, and the above materials are blended after stirring to form a decontamination layer 2. After the decontamination layer 2 is prepared, it is coated or laminated on a backing material 1, and after the decontamination layer 2 is combined with the backing material 1, an isolation layer 3 is laminated on the decontamination layer 2 to complete the preparation of the tape.

[0044] Combination Figure 2 and 3 As shown, when the above-mentioned tape is used, the isolation layer 3 is torn off, and the backing material 1 and the decontamination layer 2 are attached to the dirt layer 4 on the surface 5 of the composite post insulator. A certain force is applied by hand or machine to make the decontamination layer 2 and the dirt layer 4 adhere tightly. After a certain period of time, when the decontamination layer 2 and the dirt layer 4 fully act and the effective ingredients are immersed in the surface 5 of the composite post insulator, the tape is torn off the surface 5 of the composite post insulator. Due to the difference in bonding strength, the decontamination layer 2 peels off the dirt layer 4 from the surface 5 of the composite post insulator, thereby removing the dirt on the surface 5 of the composite post insulator.

[0045] The adhesive tape for removing dirt from the surface of the composite post insulator in this embodiment is supported by the decontamination layer 2 by providing a backing material 1, and the decontamination layer 2 is protected from being contaminated by the isolation layer 3. When in use, the decontamination layer 2 is adhered to the contaminated part of the surface 5 of the composite post insulator to remove the contamination. The bonding force between the decontamination layer 2 and the contamination is greater than the bonding force between the contamination and the silicone rubber material on the surface 5 of the composite post insulator. When the decontamination layer 2 is peeled off, the contamination on the surface 5 of the composite post insulator can be brought down, thereby effectively removing the contamination on the surface 5 of the composite post insulator. It can be seen that in this embodiment, the adhesive tape only needs to be adhered to the contaminated part of the surface 5 of the composite post insulator, and then the adhesive tape can be torn off to complete the contamination removal, which greatly improves the cleaning speed of the contamination on the surface 5 of the composite post insulator.

[0046] Furthermore, the decontamination layer 2 in the present embodiment is made of polymer material. After the decontamination layer 2 is pasted on the composite post insulator, according to the principle that the binding force between the polymer material and the dirt is greater than the binding force between the dirt and the silicone rubber material, the dirt components on the surface 5 of the composite post insulator can be taken out at the same time as the tape is peeled off, and the dirt on the surface 5 of the composite post insulator can be effectively removed. At the same time, the effective ingredients in the polymer material can partially penetrate into the silicone rubber on the surface 5 of the composite post insulator, thereby restoring the surface hydrophobicity of the composite post insulator, so that its surface state can meet the operation requirements of the power system in the shortest time, speed up the work progress, and improve work efficiency.

[0047] In another preferred embodiment based on the above embodiment, this embodiment provides a method for preparing a decontamination layer of a room temperature application device for removing dirt on the surface of a composite insulator, wherein the decontamination layer of the adhesive tape is copolymerized by a plurality of reactive monomers, and the preparation method of the decontamination layer comprises the following steps:

[0048] The viscous monomers butyl acrylate BA (7g) and isooctyl acrylate 2-EHA (20g), the internal monomer vinyl acetate VAc (7g), the functional monomer acrylic acid AA (1g), the initiator benzoyl peroxide BPO (0.06g) and different mass fractions of N,N'-methylenebisacrylamide N,N'-MBA (0, 0.05%, 0.1%, 0.15%, 0.2%) were added to 60ml ethyl acetate, ultrasonically dispersed for 30min, added to a four-necked flask equipped with a thermometer, a constant pressure titration funnel and a stirrer, and N2 was introduced for 20min, and then the temperature was raised to 80℃ for reaction for 1h. Then BA (3g), 2-EHA (10g), VAc (3g), AA (0.5g), and BPO (0.03g) were added to 40ml ethyl acetate, mixed evenly, and then added dropwise to the reaction system through a constant pressure titration funnel within 2h, and kept warm for 1h. Finally, a constant pressure titration funnel was used to drop the uniformly mixed BPO (0.03 g) and 30 ml of ethyl acetate into the reaction system within 0.5 h. After keeping the temperature at 80° C. for 1.5 h, the mixture was cooled and discharged.

[0049] It can be seen that after the decontamination layer prepared by the above method is pasted on the composite post insulator, according to the principle that the binding force between the polymer material and the dirt is greater than the binding force between the dirt and the silicone rubber material, the dirt components on the surface of the composite post insulator can be taken out at the same time as the tape is peeled off, thereby effectively removing the dirt on the surface of the composite post insulator. At the same time, the effective ingredients in the polymer material can partially penetrate into the silicone rubber on the surface of the composite post insulator, thereby restoring the surface hydrophobicity of the composite post insulator, so that its surface state can meet the operation requirements of the power system in the shortest time, speed up work progress and improve work efficiency.
