Description

Technical Field

[0001] The invention relates to the technical field of insulator surface contamination treatment, and in particular to a mechanical device and a collection method for rapid collection of insulator surface contamination. Background Art

[0002] In recent years, with the vigorous construction of power networks, the safe and stable operation of power systems has received more and more attention. As an important part of the insulation support and mechanical connection of electrical equipment, the insulation performance of insulators directly affects the stable operation of power systems. With the expansion of the scope of power grid construction and the increase in operating time, the degree of surface contamination of insulators has gradually increased. The surface contamination of insulators is mainly divided into natural contamination and industrial contamination. Natural contamination includes fine dust in the air, salt spray brought by sea breeze, etc., while industrial contamination is mainly composed of smoke and exhaust gas emitted by industrial equipment. These contaminants accumulate on the surface of insulators to form a conductive film, especially under humid conditions, which will greatly reduce the insulation level of insulators and lead to power accidents. Flashover accidents always threaten the safety of power grid operation. Therefore, according to the requirements of the operation regulations, it is necessary to regularly collect and measure the surface contamination of insulators to determine the degree of surface contamination of insulators, so as to timely prevent and eliminate the safety hazards caused by surface contamination of insulators.

[0003] The existing insulator surface pollution collection method requires operators to disassemble the insulator pieces, transport them to the ground, and use brushes, scrapers and other tools to collect the insulator surface pollution. The pollution samples are then dissolved in distilled water and collected, and then sent to the laboratory for further analysis using the equal salt density method. Although this method is simple to operate, it is extremely inefficient. During the rapid construction of the power system, the maintenance and monitoring of a large number of insulators will consume a lot of manpower and material resources. At the same time, due to the uncertainty of human operation, it is impossible to accurately determine the regional scope of pollution collection, making it difficult to standardize the collection of insulator surface pollution, which in turn leads to insufficient credibility of subsequent pollution degree analysis results. With the rapid increase in the number of power network lines put into operation, this type of insulator surface pollution collection method can no longer meet the current development trend of the power network.

[0004] With the development of industrial technology, the measurement and collection of insulator surface contamination has gradually developed towards automation and intelligence, and has gradually been divided into two types: online measurement and offline measurement. Among them, online measurement mainly uses non-contact intelligent detection, which detects the optical scattering characteristics of the insulator surface to monitor the insulator salt density, ash density, air temperature, relative humidity and other parameters in real time. However, this method is currently costly and its accuracy is greatly affected by the measurement environment. Offline measurement uses automated equipment to collect insulator surface contamination, avoiding manual operation errors and speeding up the collection efficiency, but there are still problems of high cost and high maintenance. At the same time, the miniaturization of the equipment still needs to be further improved, which makes it inconvenient to disassemble.

[0005] Therefore, how to design an automatically controlled, easily disassembled, precise, intelligent insulator surface contamination collection device to realize the intelligence and automation of insulator surface contamination collection, and then unify the insulator surface contamination collection standards, improve the insulator surface contamination collection efficiency and improve the measurement credibility, has become a key concern of academia and industry. Summary of the invention

Considering that the traditional method of collecting contamination on the surface of insulators is manual, the labor cost is high and the efficiency is low. At the same time, the consistency of the collection degree and range of contamination on the surface of insulators is poor, and the collection effect is greatly affected by human factors, resulting in a decrease in the credibility of the contamination degree analysis results; the mechanical device for rapid collection of contamination on the surface of insulators can improve the efficiency of contamination collection, unify the collection result standards to improve the credibility of insulator surface status detection.

The telescopic rod 6 can swing back and forth in a designated dirt collection area through the third driving gear in conjunction with the telescopic rotating motor 2, thereby scrubbing the dirt on the upper surface of the insulator in the dirt collection area.

[0043] The water storage tank and the collection tank in this embodiment have the following specific structures:

[0044] like Figure 2As shown, the water storage tank includes a cylindrical water storage tank body 7, and a nozzle 8 with a flow switch is provided at the lower part of the water storage tank body 7, and the nozzle 8 is connected to the wireless control box 3; distilled water for washing dirt on the surface of the insulator is stored in the water storage tank body 7. When the wireless control box 3 can control the water flow rate through the Bluetooth signal, the water outlet end of the nozzle 8 points to the area to be collected on the surface of the insulator sheet, and the distilled water output used can be pre-set and controlled by the wireless control box 3.

[0045] like Figure 2 As shown, the collecting tank includes a cylindrical collecting tank body 9, and a drainage pipe 10 is installed on the top of the collecting tank body 9; the top of the drainage pipe 10 is funnel-shaped and is located at the edge of the lower surface of the insulator and between the first metal bar 4 and the second metal bar 5; the washing sewage in the designated collection area enters the collecting tank body 9 through the drainage pipe 10 for precise collection.

[0046] The water storage tank, collection tank and drive assembly in this embodiment are installed as follows:

[0047] like Figure 2 As shown, in this embodiment, an upper fixing buckle 11 and a lower fixing buckle 12 are installed between the base and the iron cap of the insulator.

Since the upper fixing buckle 11 and the lower fixing buckle 12 are used to provide corresponding support force to the water storage tank, the collection tank and the drive assembly, the installation stability of the mechanical device can be guaranteed.

[0048] Example 2

[0049] Based on the mechanical device for quickly collecting dirt on the surface of an insulator provided in Example 1, this embodiment proposes a collection method for quickly collecting dirt on the surface of an insulator, such as Figure 3 As shown, the specific steps are as follows:

[0050] Step 1. Determine the surface area of ​​the insulator to be collected. An upper fixing buckle 11 and a lower fixing buckle 12 are installed between the base and the iron cap of the insulator to fix the main body of the pollution collection device.

[0051] Step 2. According to the surface area of ​​the insulator to be collected, fix the water storage tank to the upper end of the collection device through the upper fixing buckle 11 and the lower fixing buckle 12, and fix the collection tank to the lower end of the collection device.

[0052] Step 3. Send a control instruction to the wireless control box 3 to control the driving component to drive the collection area demarcation component and preset the opening and closing angles of the first metal strip 4 and the second metal strip 5.

[0053] Step 4: Based on the preset opening and closing angles of the first metal strip 4 and the second metal strip 5 And the length L of the brush head of the cleaning component, the area S of the dirt collection area is obtained.

[0054] The opening and closing angles of the first metal strip 4 and the second metal strip 5 are preset by the wireless control box 3 The length of the dirt collection brush head is L, and the area of ​​the dirt collection area S can be obtained by the following formula:

[0055]

[0056] Step 5. Based on the preset pollution collection standard and the pollution collection area S on the insulator surface, calculate the distilled water storage capacity Q at the flow switch of the water storage tank.

[0057] According to the preset pollution collection standard, the amount of distilled water used for collecting pollution on the insulator surface is proportional to the pollution collection area, so the distilled water output Q at the flow switch of the water storage tank is controlled as follows:

[0058] Q=k·S

[0059] Wherein, k is a ratio coefficient between the amount of distilled water collected from the insulator surface contamination and the contamination collection area, which can be preset in the wireless control box 3 .

[0060] Step 6. Adjust the parameters of the telescopic rotating motor 2 of the driving component through the wireless control box 3, preset the angular velocity ω of the dirt brush head, and the number of reciprocating rotations is n, thereby obtaining the collection time T of the dirt collection brush head in the dirt collection area on the insulator surface.

[0061] The angular velocity of the dirt brush head rotation ω is preset through the wireless control line, and the number of reciprocating rotations is n, thereby obtaining the collection time T of the dirt collection brush head in the dirt collection area on the insulator surface:

[0062]

[0063] Step 7. When the brush head of the cleaning component rotates to collect water, the nozzle 8 on the water storage tank is controlled to be closed. After the collection time T has passed, the collected water sample containing dirt in the designated collection area is drained into the collection tank body 9 through the drainage pipe 10.

[0064] Step 8. To ensure the accuracy of the dirt collection work on the insulator surface, the cleaning component can be preset to work N times, so that the driving component cooperates with the cleaning component to repeat the brushing operation N times when collecting dirt on the insulator surface.

[0065] In summary, the mechanical device for quickly collecting dirt on the surface of an insulator allows the collection of dirt on the surface of the insulator to be carried out without disassembling the insulator, and at the same time, by presetting the length L of the dirt collection brush head, the opening and closing angles of the first metal strip 4 and the second metal strip 5, Parameters such as the water output Q of the water storage tank, the angular velocity ω of the dirt brush head, the number of reciprocating rotations n, and the collection time T can ensure the consistency of the dirt collection standards; thereby providing a basis for the subsequent accurate calculation of the degree of dirt contamination on the insulator surface, and the collection process has achieved intelligence, standardization and automation.

[0066] Furthermore, this embodiment also verifies the actual effect of the mechanical device for quickly collecting contamination on the surface of insulators. Compared with the traditional method of disassembling the insulator pieces and transporting them to the ground for collecting contamination on the surface of insulators, the collection efficiency is low and the collection area cannot be accurately determined. The use of the mechanical device for quickly collecting contamination on the surface of insulators can shorten one day's maintenance work to 2 hours, and at the same time accurately determine the collection angle of contamination on the surface of insulators to be 60°, and then determine the collection area, which greatly improves work efficiency and collection accuracy.

[0067] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
