Description

Technical Field

[0001] The present invention relates to the technical field of insulator cleaning, and particularly to a tool for cleaning salt deposits on switchgear insulators. Background Art

[0002] The statements in this section merely provide background technical information related to the present disclosure and do not necessarily constitute prior art.

[0003] 35kV switchgears are currently widely used in the power system. During long-term use, the internal dust accumulation is serious. For 35kV switchgears located in coastal areas or areas with a large number of chemical plants, after running for a period of time, a large amount of dust, salt deposits, and other pollutants accumulate on the insulators inside the cabinet. During operation, the abnormal sound gradually increases, and flashover discharges often occur. Regularly cleaning the accumulated dirt is the most direct and effective method.

[0004] Currently, the cleaning of switchgears is limited to manual wiping. In addition to low efficiency, it is also difficult to improve the cleaning quality. The cleaning quality of insulators is poor, and there is no special cleaning tool for the edges and seams. After manual cleaning, the abnormal sound still occurs frequently during operation. Summary of the Invention

[0005] In order to solve the above problems, the present disclosure proposes a tool for cleaning salt deposits on switchgear insulators, which can achieve automatic cleaning of the insulators inside the switchgear and cleaning of the edges and corners.

[0006] To achieve the above object, the present disclosure adopts the following technical solutions:

The water outlets are connected to the pump through water pipes, and the air outlets are connected to the blower through air pipes. Both the blower and the pump are connected to the control panel.

[0008] Compared with the prior art, the beneficial effects of the present disclosure are as follows:

[0009] 1. By setting the external wiping unit and the micro cleaning unit, the present disclosure realizes automatic cleaning of the insulators inside the switchgear and cleaning of the edges and corners.

[0010] 2. By arranging air outlets and water outlets at the scrubbing head, spraying water through the water outlets to the scrubbing area can ensure the cleaning effect. After scrubbing, the air from the air outlets dries the scrubbing area, achieving the purpose of rapid cleaning and rapid drying, improving the efficiency, and reducing the power outage time.

[0011] 3. The present disclosure provides a temperature conversion unit at the scrubbing head, which can obtain the temperature at the scrubbing head and adjust the heating level of the heating unit in the air duct according to this temperature, so as to adjust the temperature of the air outlet and ensure the effective drying at the scrubbing area.

The wind temperature detection sensor 29 is used to detect the temperature at the wiping tool, so as to control the operation of the electric heater through the temperature conversion unit 12 and adjust the wind temperature at the air outlet.

[0075] By fixing the scrubbing head on the follower disk, the disassembly and replacement of the scrubbing head are realized, so that the appropriate scrubbing head can be replaced according to the specific working occasion.

[0076] In specific implementation, the scrubbing heads mainly include arc-shaped scrubbing heads and cylindrical scrubbing heads. The arc-shaped scrubbing heads can be further divided into small arc-shaped scrubbing heads and large arc-shaped scrubbing heads. Combining with the materials, the scrubbing heads are divided into: soft hair type small arc-shaped scrubbing head 62, soft sponge type small arc-shaped scrubbing head 63, hard sponge type small arc-shaped scrubbing head 64, soft hair type cylindrical small scrubbing head 65, soft sponge type cylindrical small scrubbing head 66, hard sponge type cylindrical small scrubbing head 67, soft hair type large arc-shaped scrubbing head 68, soft sponge type large arc-shaped scrubbing head 69 and hard sponge type large arc-shaped scrubbing head 70. For different types of insulators, different degrees of dirt and dirt types, the corresponding scrubbing heads are selected for the scrubbing process.

[0077] The arc-shaped scrubbing head is used for the external insulation part of the through-cabinet and post insulators, and can penetrate into them for cleaning. By replacing different sizes, the best fit can be achieved.

[0078] For different soft hair type, soft sponge type and hard sponge type, they are gradually replaced according to the dirt or crystal type on the insulation surface or the scrubbing process to achieve the best cleaning effect. For example, at the beginning, the soft hair type can be used to better clean the surface salt crystal insulators. Its texture is rough. After cleaning, the surface is smooth, but the salt adheres evenly. At this time, the soft sponge type can be used to clean the attached fine salt to the greatest extent. Finally, the hard sponge is used to clean the surface water and pollutants, which is convenient for the final drying.

[0079] The cylindrical scrubbing head is convenient for cleaning the inner surface of the cylindrical insulator or the flat insulator.

[0080] The external wiping unit adopts the method of having the scrubbing head outside, which is convenient for entering the inner cavity of the insulator for wiping work. It is fixed by high-elastic steel bars. There are air ducts, water pipes and line pipelines inside the unit, and multiple wiping tools can be strung together to form a wiping unit, which is convenient for quick cleaning.

[0081] For the convenience of cleaning corners and crevices, a micro cleaning unit capable of connecting to the composite pipeline interface is also provided.

[0082] The micro cleaning unit is as Figure 13 shown, including a fixed pipe, which is connected to the composite pipeline interface through the fixed pipe. A control panel 77 is arranged on the fixed pipe, and a rotating shaft is arranged inside the fixed pipe. One end of the rotating shaft is provided with a fan blade 78, and the other end is provided with a scrubbing head 73. The air outlet of the air duct is located at the fan blade 78. The air in the air duct blows the fan blade 78, and the rotation of the fan blade 78 drives the rotating shaft to rotate, thereby driving the scrubbing head 73 to rotate for scrubbing. An air outlet and a water outlet are arranged at the scrubbing head 73. The water outlet is communicated with a spray nozzle 74, and the spray nozzle 74 is connected to a water pipe. The liquid in the water pipe is sprayed to the cleaning area through the spray nozzle 74. The air outlet 72 is connected to a short air duct, and the air inlet of the short air duct is located at the fan blade. The sundries at the wiping area are blown clean through the air outlet, and the surface of the wiping area is dried. A water control switch 76 is arranged at the spray nozzle 74, and the spraying and stopping of water are controlled through the water control switch 76. A lighting lamp 79 is arranged at the scrubbing head 73, and the lighting lamp 79 is fixed on the fixed pipe. The wiping effect can be viewed through the lighting lamp 79. In order to ensure the good rotation effect of the rotating shaft, the rotating shaft is connected to the fixed pipe through a bearing 75. The scrubbing head here is set as a detachable structure, which is convenient for replacing the scrubbing head.

[0083] Since a water outlet is arranged at the scrubbing head to spray water on the scrubbing position, to prevent the sprayed liquid from affecting the devices inside the switch cabinet, a water receiver is arranged at the insulating part during cleaning for liquid recovery.

[0084] The water receiver includes a dripping type water receiver and a water scraping type water receiver. The dripping type water receiver is mainly used for the recovery of the cleaning liquid of the horizontal insulating part, and the water scraping type water receiver is mainly used for the recovery of the cleaning liquid of the vertically placed insulating part.

[0085] The dripping type water receiver is as Figure 14 shown, including a hard shell 81. The end of the hard shell 81 is provided with a water baffle. The cleaning liquid is received through the hard shell 81. A magnet 80 is arranged at the water baffle at one end of the hard shell 81. The dripping type water receiver is adsorbed on the switch cabinet body through the magnet 80, generally adsorbed below the insulating part to be cleaned. The hard shell 81 is also communicated with a drain pipe 82. The drain pipe 82 is usually placed at the lower part of the hard shell 81, and the liquid is recovered through the drain pipe 82.

[0086] The water scraping type water receiver is as Figure 15As shown, it includes a waterproof soft bag 88. One end of the waterproof soft bag is provided with an elastic support frame 85, and the other end is provided with a self-adhesive fastener 86. An elastic plastic seal 87 is arranged inside the self-adhesive fastener 86. Self-adhesive sealing strips 84 are arranged on both sides of the waterproof soft bag. The self-adhesive fastener 86 can wrap around the bottom of the insulating part and be closely pasted and fixed. It has an elastic plastic sealing and fixing part inside, which fits on the insulating part to prevent water leakage. After the self-adhesive sealing strips are pasted, the waterproof soft bag forms a container that does not leak liquid. The elastic support frame is at the top to support the water receiver. The waterproof soft bag 88 is also connected to a drain pipe 83 for drainage and recycling.

[0087] A salt accumulation cleaning tool for switchgear insulating parts disclosed in this embodiment realizes the automatic cleaning of the insulating parts in the switchgear and the cleaning of the edges and corners by setting an external wiping unit and a micro cleaning unit. An air outlet and a water outlet are arranged at the wiping head. Cleaning liquid is sprayed to the wiping area through the water outlet, which can ensure the cleaning effect. After wiping, the air from the air outlet dries the wiping area, achieving the purpose of rapid cleaning and rapid drying, improving the efficiency and reducing the power outage time.

[0088] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the above embodiments, those of ordinary skill in the art should understand that: the specific implementation manners of the present invention can still be modified or equivalently replaced, and any modification or equivalent replacement without departing from the spirit and scope of the present invention shall be covered by the protection scope of the claims of the present invention.
