Description

Technical Field

[0001] This invention relates to the field of cable treatment technology, and in particular to a device for removing and recoating RTV anti-flashover coating on transmission line insulators. Background Technology

[0002] Silicone rubber (RTV) is a new type of heat-resistant polymer elastic material. Its molecular backbone is composed of silicon and oxygen atoms, resulting in a particularly stable structure. The most significant characteristics of silicone rubber are its superior high-temperature and low-temperature resistance, with a service temperature range of -100℃ to 300℃. It exhibits excellent aging resistance (after several years of outdoor exposure in a free state, the properties of silicone rubber show no significant change), and possesses excellent electrical insulation properties. It is also odorless, non-toxic, and meets national health standards. Even after 20 years of outdoor exposure, the physical and mechanical properties of silicone rubber will not change significantly. It is also exceptionally heat and cold resistant, with a service life of several years at 150℃, and can be used continuously for half a month even at 300℃. It retains its rubber flexibility even when cooled to -120℃. Silicone rubber products are widely used in industrial machinery, aerospace, automotive, electronics, construction, pharmaceutical, chemical, and food industries. It is the best rubber material for making seals, heat-resistant gaskets, partitions, shock-absorbing materials, insulating components, and outdoor sealing components. With the widespread use of silicone rubber, the problems of cleaning and removing silicone rubber are also increasing.

[0003] RTV is used as an anti-flashover material in the insulating ceramic parts of electrical equipment in power systems, protecting the equipment from corona, ultraviolet radiation, water corrosion, and air pollution, resulting in a long service life and minimal maintenance.

[0004] RTV anti-flashover coating is applied to the surface of porcelain or glass insulators, transforming the originally hydrophilic surface into a hydrophobic one, significantly improving the flashover voltage. As an organic polymer material, RTV coating inevitably ages under long-term outdoor operation conditions, exposed to strong electric fields, ultraviolet radiation, temperature fluctuations, and acid rain corrosion. This leads to deterioration phenomena such as peeling, chalking, fading, flaking, and decreased hydrophobicity, thus affecting its anti-flashover performance. In heavily polluted areas, such as near cement plants, 2-3 years of operation is sufficient for RTV coating failure. Therefore, without timely intervention, the probability of flashover in transmission line insulators increases significantly, seriously threatening the safe operation of the power grid. RTV recoating is an effective means of repairing aging RTV coatings, improving their anti-pollution performance without replacing the insulators, ensuring the safe operation of the power system. Therefore, when aging and performance degradation of the coating are observed, RTV coating needs to be reapplied to the insulator surface to ensure the safe operation of the power grid. DL / T627—2012, "Room Temperature Curing Silicone Rubber Anti-Flashover Coating for Insulators," stipulates that when recoating a failed RTV coating, the surface contaminant must be removed or the RTV coating must be completely removed before recoating. There are two main methods for removing RTV coating: chemical and physical methods.

[0005] Currently, RTV coating is mainly applied manually by workers to insulated porcelain insulators. While this method allows for flexible application to different locations on the insulated porcelain components, it has the following drawbacks:

[0006] 1) During the spraying process, a large amount of paint will not be sprayed onto the ceramic parts but will be sprayed into the air, which is not only inefficient and wasteful, but also pollutes the surrounding environment.

[0007] 2) Construction quality mainly depends on the experience of the construction personnel, which makes it difficult to guarantee the uniformity of the coating thickness. This leads to a decrease in water repellency, and the problems of aging and peeling become increasingly prominent, making it difficult to guarantee the quality of the coating.

[0008] 3) The quality of spraying is greatly affected by climatic conditions (weather, temperature, humidity, wind speed, etc.). Therefore, we propose a device for removing and recoating the RTV anti-flashover coating on transmission line insulators. Summary of the Invention

[0009] (a) Technical problems to be solved

[0010] To address the shortcomings of existing technologies, this invention provides a device for removing and recoating RTV anti-flashover coating on transmission line insulators. This device ensures that after cleaning the old RTV coating on the surface of the switch insulator, the new RTV coating has a uniform thickness, thereby extending the service life of the switch insulator. It solves the technical problem of the difficulty in removing and recoating the existing RTV anti-flashover coating on transmission line insulators, and also improves the ease of use of the device.

[0011] (II) Technical Solution

[0012] To achieve the above objectives, the present invention provides the following technical solution:

[0013] A device for removing and recoating RTV anti-flashover coating on transmission line insulators includes a handheld body with a handle and a trigger (power switch) for controlling the power supply of a battery to various internal electrical components. The body also contains a delivery assembly for transporting solvent and RTV liquid stored in a storage box to a brush head, which is then applied to the surface of the cable. The delivery of the solvent or RTV liquid is selected via a selector knob, allowing either solvent or RTV liquid to flow into the brush head. For example, when it is necessary to remove and recoat the insulator... When cleaning RTV from the cable surface, the solvent is controlled to flow into the delivery assembly, which then feeds the solvent into the brush head. Simultaneously, the brush head rotates, evenly applying the solvent to the outside of the cable, thus dissolving the RTV and removing it from the cable. Similarly, when applying RTV to the cable surface, the RTV liquid is controlled to flow into the delivery assembly, which then feeds the RTV liquid into the brush head. The brush head rotates, evenly applying the RTV liquid to the outside of the cable, thus uniformly coating the cable surface with RTV liquid.

[0014] The main body is carried by a handheld device, with a brush head with bristles at the front end, which can polish the RTV on the surface of the cable and apply RTV fluid at the same time.

[0015] A storage box, mounted on top of the main body, stores the solvent and RTV fluid, providing separate storage space for each. This facilitates control of the flow of either solvent or RTV fluid into the delivery assembly when the switch knob is rotated.

[0016] The delivery assembly is installed inside the main body, and the end of the delivery assembly is connected to the brush head. It is used to drive the brush head to rotate and selectively deliver solvent or RTV liquid to the brush head, thereby achieving the elimination or application of RTV.

[0017] The conveying assembly includes a connector (for docking with a brush head) and a docking cylinder connected to the rear end of the connector. The connector and the docking cylinder can rotate relative to each other. An extrusion screw is inserted inside the docking cylinder. When the extrusion screw rotates, it can convey the raw material inside the docking cylinder to the outside, thereby achieving the purpose of material conveying. The extrusion screw is driven to rotate by a drive motor installed inside the main body. Therefore, the start and stop of the extrusion screw can be controlled by controlling the power on and off of the drive motor.

[0018] The storage box delivers solvent or RTV liquid to the docking cylinder through a pipeline, thereby providing raw materials for the docking cylinder.

[0019] The connector is driven to rotate by a motor installed inside the main body. Therefore, the rotation of the connector can be controlled by controlling the power supply to the motor, which in turn drives the brush head installed at the front end of the connector to rotate, providing rotational power to the brush head.

[0020] Preferably, the connector is movably connected to the docking cylinder, meaning it can rotate relative to it, and a linkage gear is installed on the outside of the connector.

[0021] The motor has a drive gear mounted on its output shaft, and the motor meshes with the connecting gear through the drive gear. Therefore, when the motor is powered on and rotates, it can drive the drive gear on its output shaft to rotate. Since the drive gear meshes with the connecting gear, when the motor rotates, it can drive the connecting gear and the coupling connected to the connecting gear to rotate together.

[0022] Preferably, the rear end of the extrusion screw is connected to a connecting seat, and the connecting seat is connected to the docking cylinder through a bearing, thereby ensuring the positional stability between the extrusion screw and the docking cylinder and improving the rotational stability of the extrusion screw;

[0023] The output shaft of the drive motor is connected to the connecting seat. When the drive motor is powered on and rotates, it can drive the extrusion screw connected to the connecting seat to rotate synchronously, thereby stably conveying the raw material outward.

[0024] Preferably, the brush head is connected to the discharge port of the connector. When the extrusion screw rotates, the raw material is discharged outward through the discharge port. The raw material inside the connector enters the brush head through the discharge port. Since the brush head is connected to the discharge port, the raw material can enter the brush head when it is discharged along the discharge port and be applied to the outside of the cable through the brush head.

[0025] Preferably, the brush head includes a feed tube that is sleeved with the discharge port. The raw material can move along the feed tube and eventually enter the bristles. The end of the feed tube is connected to a connecting plate. The outer wall of the connecting plate is uniformly adhered with bristles. So when the raw material is transported along the feed tube to the bristle position, the raw material is applied to the bristles and then applied to the outer wall of the cable by the bristles.

[0026] The connector conveys the raw material to the brush bristles through a feed pipe, forming a feed pipeline, thereby connecting the brush bristles to the raw material.

[0027] Preferably, the storage box includes a liquid chamber located on the top of the main body, and the liquid chamber contains a solvent and RTV liquid to store the raw materials for convenient subsequent transportation.

[0028] The liquid tank delivers the solvent and RTV liquid to the docking cylinder through a pipeline, thereby providing space for the raw materials.

[0029] Preferably, the conveying assembly further includes a material conveying component sleeved outside the docking cylinder, and the material conveying component includes an upper sleeve and a lower sleeve corresponding to each other, thereby clamping the outer wall of the docking cylinder and connecting the material conveying component to the docking cylinder. Multiple connecting pipes are installed on the outside of the upper sleeve, and two of the connecting pipes are connected to the storage box through pipes (communicating with the solvent or RTV liquid inside the storage box respectively), so that the solvent or RTV liquid can enter the connecting pipes along the pipes.

[0030] Preferably, the docking cylinder has multiple through holes on its exterior, and the number of through holes is the same as the number of connecting pipes. This allows the raw material connected to the connecting pipe to enter the docking cylinder along the through holes when the corresponding through hole corresponds to the connecting pipe, thereby participating in the extrusion work of the extrusion screw and finally conveying the raw material to the brush head.

[0031] The through hole is located on the rotation path of the connecting pipe, and there is only one through hole on the same rotation path, so as to prevent two different materials from entering the docking cylinder at the same time, thereby preventing the two different materials from conflicting.

[0032] Only one through hole is connected to the connecting pipe at any given time, ensuring that only one type of raw material can be transported at a time. Other raw materials cannot connect to the through hole, so they cannot enter the connecting cylinder along the through hole and do not participate in the extrusion work of the extrusion screw.

[0033] Preferably, a linkage rod is installed inside the main body, and one end of the linkage rod is equipped with an adjusting gear, while the other end extends to the outside of the main body;

[0034] The adjusting gear meshes with the docking gear outside the docking cylinder, causing the docking cylinder to move in conjunction with the connecting rod.

[0035] One end of the connecting rod extending from the main body is connected to a conversion knob for easy manual rotation. When the conversion knob is rotated, it drives the connecting rod to rotate as well. Since the adjusting gear at one end of the connecting rod meshes with the docking gear outside the docking cylinder, the docking cylinder can be rotated when the conversion knob is rotated. Furthermore, since the docking cylinder has a through hole on its exterior, the position of the through hole can be adjusted when the docking cylinder rotates, so that the corresponding through hole connects to the wiring pipe (the wiring pipe that connects to the specific raw material), thereby allowing the stored specific raw material to enter the docking cylinder and achieve the purpose of switching.

[0036] (III) Beneficial Effects

[0037] By using a switch button to switch between the solvent and RTV liquid delivered by the conveying component, and then having the brush head wash the material onto the outer wall of the cable, the technical problem of the difficulty in removing and recoating the existing RTV anti-flashover coating on transmission line insulators is effectively solved. This enables rapid switching of materials, reduces the difficulty of RTV application or removal, and improves the convenience of cable cleaning. Attached Figure Description

[0050] This application provides a device for removing and recoating RTV anti-flashover coating on transmission line insulators, which effectively solves the technical problem of the difficulty in removing and recoating existing RTV anti-flashover coatings on transmission line insulators. In the existing removal and recoating of RTV anti-flashover coatings on transmission line insulators, a switching button is used to switch between the solvent and RTV liquid delivered by the conveying component, and then the brush head washes the material onto the outer wall of the cable, thereby realizing rapid switching of materials. At the same time, it can also reduce the difficulty of RTV application or RTV removal and improve the convenience of cable cleaning.

[0051] Example 1

[0052] The technical solution in this application embodiment effectively solves the technical problem of the difficulty in removing and recoating the existing RTV anti-flashover coating on transmission line insulators. The overall approach is as follows:

[0053] To address the problems existing in the prior art, this invention provides a device for removing and recoating RTV anti-flashover coating on transmission line insulators, such as... Figures 1-2As shown, the device includes a handheld body 1 with a handle 2 and a trigger (power switch) on the handle 2 for controlling the power supply of the battery to the various electrical components inside the device. The body 1 also contains a delivery assembly 3 for transporting the solvent and RTV fluid stored in the storage box 4 to the brush head 6, which then applies the solution to the surface of the cable. The delivery of the solvent and RTV fluid is selected by a selector knob 37, allowing either solvent or RTV fluid to flow into the brush head 6. For example, when RTV application is needed on the cable surface... During cleaning, the solvent is controlled to flow into the conveying assembly 3, which then delivers the solvent to the brush head 6. Simultaneously, the brush head 6 rotates, evenly applying the solvent to the outside of the cable, thereby dissolving the RTV on the cable's exterior and eliminating it. Similarly, when RTV needs to be applied to the cable surface, the RTV liquid is controlled to flow into the conveying assembly 3, which then delivers the RTV liquid to the brush head 6. Simultaneously, the brush head 6 rotates, evenly applying the RTV liquid to the outside of the cable, thus uniformly applying RTV liquid to the cable's exterior.

[0054] The main body 1 is carried by a handheld device, and a brush head 6 with bristles 61 is installed at the front end. It can polish the RTV on the surface of the cable and apply RTV liquid at the same time.

[0055] like Figure 2 As shown, the storage box 4, installed on top of the main body 1, is used to store the solvent and RTV liquid, providing an independent storage space for the solvent and RTV liquid, facilitating the control of the flow of the solvent or RTV liquid into the delivery assembly 3 when the conversion knob 37 is rotated; and

[0056] like Figure 3 and Figure 4 As shown, the delivery component 3 is installed inside the body 1, and the end of the delivery component 3 is connected to the brush head 6. It is used to drive the brush head 6 to rotate and selectively deliver solvent or RTV liquid to the brush head 6, thereby achieving the elimination or application of RTV.

[0057] The conveying assembly 3 includes a connector 31 (for docking with the brush head 6) and a docking cylinder 32 connected to the rear end of the connector 31. The connector 31 and the docking cylinder 32 can rotate relative to each other. An extrusion screw 52 is inserted inside the docking cylinder 32. When the extrusion screw 52 rotates, it can convey the raw material inside the docking cylinder 32 to the outside, thereby achieving the purpose of material conveying. The extrusion screw 52 is driven to rotate by a drive motor 51 installed inside the body 1. Therefore, the start and stop of the extrusion screw 52 can be controlled by controlling the power on and off of the drive motor 51.

[0058] Storage box 4 delivers solvent or RTV liquid to docking cylinder 32 through a pipeline, thereby delivering the solvent and RTV liquid stored in storage box 4 to docking cylinder 32 and providing raw materials for docking cylinder 32;

[0059] The connector 31 is driven to rotate by a motor 72 installed inside the main body 1. Therefore, the rotation of the connector 31 can be controlled by controlling the power supply of the motor 72, which in turn drives the brush head 6 installed at the front end of the connector 31 to rotate, providing rotational power for the brush head 6.

[0060] In some examples, such as Figure 5 As shown, the connector 31 and the docking cylinder 32 are movably connected, meaning they can rotate relative to each other, and a linkage gear 71 is installed on the outside of the connector 31.

[0061] The output shaft of the motor 72 is equipped with a drive gear, and the motor 72 meshes with the connecting gear 71 through the drive gear. Therefore, when the motor 72 is powered on and rotates, it can drive the drive gear on its output shaft to rotate. Since the drive gear meshes with the connecting gear 71, when the motor 72 rotates, it can drive the connecting gear 71 and the coupling 31 connected to the connecting gear 71 to rotate together.

[0062] In some examples, such as Figure 4 and Figure 5 As shown, the rear end of the extrusion screw 52 is connected to a connecting seat 53, and the connecting seat 53 is connected to the docking cylinder 32 through a bearing, thereby ensuring the positional stability between the extrusion screw 52 and the docking cylinder 32 and improving the rotational stability of the extrusion screw 52.

[0063] The output shaft of the drive motor 51 is connected to the connecting seat 53. When the drive motor 51 is powered on and rotates, it can drive the extrusion screw 52 connected to the connecting seat 53 to rotate synchronously, thereby stably conveying the raw material outward.

[0064] In some examples, such as Figure 1 and Figure 9 As shown, the brush head 6 is connected to the discharge port of the connector 31. When the extrusion screw 52 rotates, the raw material is discharged outward through the discharge port. The raw material inside the connector 31 enters the brush head 6 through the discharge port. Since the brush head 6 is connected to the discharge port, the raw material can enter the brush head 6 when it is discharged along the discharge port and be applied to the outside of the cable through the brush head 6.

[0065] In some examples, such as Figure 1 and Figure 9As shown, the brush head 6 includes a feed tube 62 that is sleeved with the discharge port. The raw material can move along the feed tube 62 and eventually enter the bristles 61. The end of the feed tube 62 is connected to a connecting plate 63. The outer wall of the connecting plate 63 is uniformly adhered with bristles 61. So when the raw material is transported along the feed tube 62 to the position of the bristles 61, the raw material is applied to the bristles 61 and then applied to the outer wall of the cable by the bristles 61.

[0066] Among them, the connector 31 conveys the raw material to the bristles 61 through the conveying pipe 62, forming a conveying pipeline, thereby connecting the bristles 61 with the raw material.

[0067] In some examples, such as Figure 2 As shown, the storage box 4 includes a liquid chamber 41 opened on the top of the main body 1, and the liquid chamber 41 contains solvent and RTV liquid, thereby storing the raw materials for convenient subsequent transportation.

[0068] The liquid tank 41 delivers the solvent and RTV liquid to the docking cylinder 32 through a pipe, thereby providing space for the raw materials. The outside of the liquid tank 41 is connected to the cover plate 42 by a hinge.

[0069] In some examples, such as Figures 6-8 As shown, the conveying assembly 3 also includes a material conveying component 33 sleeved outside the docking cylinder 32. The material conveying component 33 includes an upper sleeve 331 and a lower sleeve 332 corresponding to each other, thereby clamping the outer wall of the docking cylinder 32 and connecting the material conveying component 33 to the docking cylinder 32. Multiple connecting pipes 334 are installed on the outside of the upper sleeve 331, and two of the connecting pipes 334 are connected to the storage box 4 through pipes (connected to the solvent or RTV liquid inside the storage box 4 respectively), so that the solvent or RTV liquid can enter the connecting pipe 334 along the pipe.

[0070] The wiring conduit 334 is installed on the socket 333, and the socket 333 is installed on the upper sleeve 331, as follows. Figure 7 and Figure 8 As shown.

[0071] In some examples, such as Figure 8 As shown, the docking cylinder 32 has multiple through holes on its exterior, and the number of through holes is the same as the number of connecting pipes 334. This allows the raw material connected to the connecting pipe 334 to enter the docking cylinder 32 along the through holes when the corresponding through holes correspond to the connecting pipes 334, thereby participating in the extrusion work of the extrusion screw 52 and finally conveying the raw material to the brush head 6.

[0072] The through hole is located on the rotation path of the connector 334, and there is only one through hole on the same rotation path (that is, the path that the connector 334 moves across the outside of the docking cylinder 32 when the connector 334 rotates relative to the docking cylinder 32), so as to prevent two different materials from entering the docking cylinder 32 at the same time, thereby preventing the two different materials from conflicting.

[0073] Only one through hole is connected to the connector 334 at any given time, ensuring that only one type of raw material can be transported at a time. Other raw materials cannot connect with the through hole, so they cannot enter the connecting cylinder 32 along the through hole and do not participate in the extrusion work of the extrusion screw 52.

[0074] In some examples, a linkage 35 is installed inside the body 1, and an adjusting gear 36 is installed at one end of the linkage 35, while the other end extends to the outside of the body 1.

[0075] Among them, the adjusting gear 36 meshes with the docking gear 34 outside the docking cylinder 32, so that the docking cylinder 32 and the connecting rod 35 move together.

[0076] One end of the connecting rod 35 extending out of the main body 1 is connected to a conversion knob 37 for easy manual rotation. When the conversion knob 37 is rotated, it can drive the connecting rod 35 to rotate together. Since the adjusting gear 36 at one end of the connecting rod 35 meshes with the docking gear 34 outside the docking cylinder 32, the docking cylinder 32 can be rotated when the conversion knob 37 is rotated. Since the docking cylinder 32 has a through hole on its outside, the position of the through hole can be adjusted when the docking cylinder 32 rotates, so that the corresponding through hole is connected to the wiring pipe 334 (the wiring pipe 334 connected to the specific raw material), thereby allowing the stored specific raw material to enter the docking cylinder 32 to achieve the purpose of switching.

[0077] In practice, when on-site workers need to apply RTV coating or touch-up coating to the switch, they first select the solvent compartment on the device knob, pull the trigger, and evenly apply the solvent to the switch surface. After letting it stand for ten minutes, rotate the switch knob 37 to the pure polishing state to polish away any remaining RTV on the equipment.

[0078] After cleaning the residual RTV on the equipment, switch the device conversion knob 37 to the RTV compartment, and use the brush bristles 61 to evenly apply the RTV to the surface of the equipment. Let it stand for a period of time until the RTV solidifies. If any missed areas are found, reapply the RTV until the surface of the equipment is evenly covered with RTV.

[0079] When cleaning the RTV on the cable surface is required, first turn the conversion knob 37 to rotate the connecting rod 35. Since the adjusting gear 36 at one end of the connecting rod 35 meshes with the docking gear 34 on the outside of the docking cylinder 32, rotating the conversion knob 37 will rotate the docking cylinder 32. Because the docking cylinder 32 has a through hole on its exterior, the position of the through hole can be adjusted during rotation, allowing the corresponding through hole to connect with the connecting pipe 334 (the connecting pipe 334 that connects to the solvent), thereby allowing the solvent to enter the docking cylinder 32. The purpose of switching is that the solvent flows into the docking cylinder 32, and then the extrusion screw 52 is controlled to rotate, so that it conveys the raw material inside the docking cylinder 32 to the outside, thereby achieving the purpose of raw material conveying. The extrusion screw 52 is driven to rotate by the drive motor 51 installed inside the body 1. Therefore, by controlling the power on and off of the drive motor 51, the start and stop of the extrusion screw 52 can be controlled. Then, the solvent is sent into the brush head 6 by the docking pipe. At the same time, the brush head 6 starts to rotate, and the solvent is evenly applied to the outside of the cable, thereby dissolving the RTV on the outside of the cable and eliminating the RTV on the cable.

[0080] Similarly, when RTV needs to be applied to the cable surface, first rotate the conversion knob 37 to rotate the connecting rod 35. Since the adjusting gear 36 at one end of the connecting rod 35 meshes with the docking gear 34 on the outside of the docking cylinder 32, rotating the conversion knob 37 will drive the docking cylinder 32 to rotate. Because the docking cylinder 32 has a through hole on its outside, the position of the through hole can be adjusted when the docking cylinder 32 rotates, so that the corresponding through hole connects to the connecting pipe 334 (the connecting pipe 334 that connects to the RTV fluid), thereby allowing the RTV fluid to enter the docking cylinder 32, achieving the switching purpose. At this time, the RTV liquid flows into the docking cylinder 32, and then the extrusion screw 52 is controlled to rotate, so that it conveys the raw material inside the docking cylinder 32 to the outside, thereby achieving the purpose of raw material conveying. The extrusion screw 52 is driven to rotate by the drive motor 51 installed inside the body 1. Therefore, by controlling the power on and off of the drive motor 51, the start and stop of the extrusion screw 52 is controlled, and the RTV liquid flows into the conveying component 3. Then, the conveying component 3 sends the RTV liquid into the brush head 6. At the same time, the brush head 6 starts to rotate, and the RTV liquid is evenly applied to the outside of the cable, thereby evenly applying the RTV liquid to the outside of the cable.

[0081] Example 2

[0082] Based on Example 1, this embodiment of the application sets up two sets of storage boxes simultaneously to facilitate individual replacement, thereby ensuring the stability of replacement and making adjustments more targeted. The overall idea is as follows:

[0083] Storage box 4 comprises two sets, and the two sets of storage boxes 4 respectively contain solvent and RTV solution, such as Figure 10As shown.

[0084] Body 1: Made of insulating engineering plastic, with a trigger at the hand grip 2. The handle contains a built-in battery and motor. When the trigger is pulled, the motor drives the guide rod to rotate and guide the corresponding liquid out of the liquid tank 41.

[0085] Storage box 4: A storage box 4 is provided on the upper part of the device body 1. There are two storage boxes 4, one of which is a solvent compartment containing the solvent for dissolving RTV left by the cleaning switch, and the other compartment is filled with RTV.

[0086] A replaceable polishing and liquid brush head 6 is installed at the end of the conveying component 3. The brush head 6 has a bristle head that can remove the old RTV and also apply the new RTV evenly to the switch surface.

[0087] A conversion knob 37 is provided at the tail of the device body 1, which is divided into three positions, corresponding to the RTV compartment, solvent compartment, and pure polishing state (even if the through hole and the wiring pipe 334 that is not connected to the storage box 4 are connected).

[0088] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
