Description

Technical Field

[0001] The invention relates to the technical field of insulator surface contamination treatment, and in particular to a device and method for quickly collecting contamination on the lower surface of an insulator. Background Art

[0002] In the power transmission and distribution system, insulators are widely used to support transmission lines to prevent current from flowing to the ground. The problem of insulator surface contamination has become an important factor affecting the stability and safety of power system operation. As a key component in the power system, the surface contamination of insulators will lead to a decrease in insulation performance, increase the risk of discharge, and even cause power equipment failure and power outages in severe cases. The contamination on the surface of insulators mainly comes from industrial pollution, agricultural activities, transportation, and dust, salt spray and other substances in the natural environment. After these contaminants are deposited on the surface of the insulator, they will form a conductive film when eroded by humid weather or rain, which will reduce the insulation performance of the insulator. This situation is particularly serious in coastal areas or industrial areas. The contamination problem not only affects the normal operation of the power system, but also increases the difficulty and cost of maintenance and overhaul.

[0003] According to the structural shape characteristics of insulators, the current pollution collection methods include disassembly manual collection and automatic collection devices. Disassembly manual collection requires operators to wipe the surface of the insulator with cotton yarn, brushes or other simple tools, collect the pollution samples in a container, and then send them to the laboratory for analysis. This method requires simple equipment and low cost, but it has a large workload and low efficiency. In high-voltage power systems, there are a large number of insulators, and manual cleaning and collection of pollution samples one by one requires a lot of time and human resources. The repeatability and accuracy of the disassembly manual sampling results are greatly affected by the experience and skills of the operators. Different operators may have differences in operating techniques, force and sampling locations, resulting in large differences in the pollution samples collected from the same insulator at different times and by different operators. This inconsistency reduces the credibility of laboratory analysis results, affects the accurate judgment of the pollution status of the insulator surface, and easily destroys the performance of the insulator. It cannot meet the current development situation when there are many transmission lines.

[0004] With the development of technology, automated collection devices have gradually emerged. These devices are usually composed of robotic arms, sensors and control systems, which can realize the automatic collection of dirt on the surface of insulators. For example, some devices clean the surface of insulators through rotating brushes or vibrators, and collect dirt samples into specific containers. These devices can accurately locate and detect the degree of dirt on the surface of insulators, reduce errors in human operation, and greatly improve sampling efficiency and accuracy. Although automated collection devices save manpower, their high cost and maintenance requirements are also important factors to consider. The purchase cost of automated devices is high, the initial investment is large, and regular maintenance and calibration are required during use to ensure their normal operation and accuracy. In addition, it is difficult to adapt to the gully structure and ups and downs of the insulator surface, and there are still some limitations in the effective collection of insulator dirt.

[0005] Therefore, how to design a convenient and fast pollution collection device that can adapt to the different shapes of the lower surface of insulators to efficiently collect the pollution on the surface of the insulator while reducing resource consumption and environmental impact. Summary of the invention

[0006] In view of the above-mentioned shortcomings of the current method for collecting contamination on the lower surface of insulators during the maintenance of power equipment, the present invention proposes a rapid collection device for contamination on the lower surface of insulators to improve the efficiency and accuracy of insulator contamination collection. The traditional manual collection method is inefficient, labor-intensive, and difficult to cover the complex geometric structure of the lower surface of the insulator, resulting in the repeatability and accuracy of the collected data being affected by the experience and skills of the operator. The present invention aims to improve the collection adaptability functionality. The device adopts a chain structure unit, which can quickly adapt to the ups and downs of the lower surface of the insulator to achieve efficient contamination collection. It is also equipped with an angle and length scale, which can digitally display the angle of the collection area, calculate the collection area, accurately measure and record the collection area of ​​the polluted part of the insulator surface, and ensure the accuracy of the data. Furthermore, the present invention focuses on resource utilization and safety.

The PLC controller can obtain the collection area according to the angle and length of the two groups of chain structure units, thereby adjusting the flushing intensity and time of the contamination collection area on the lower surface of the insulator by distilled water through the water flow controller.

[0008] Furthermore, the water storage device is installed above the base of the insulator to be sampled through a first clip and a first pillar; one end of the first pillar contacts the outer edge of the insulator to be sampled, and the other end is detachably installed on the insulator base through the first clip, and the bottom of the water storage device is fixedly installed on the first pillar and close to the insulator base.

[0009] Furthermore, the collecting device is installed on the outer edge of the insulator to be sampled through a second buckle and a second pillar; one end of the second pillar is fixedly connected to the bottom of the collecting device, and the other end is detachably installed on the insulator iron cap through a second buckle.

[0010] Furthermore, a sealable cover is installed at the top opening of the collecting device.

[0011] Furthermore, a water outlet is provided at the bottom of the collecting device, and the collecting device can be connected to an external container pipeline through the water outlet.

[0012] Furthermore, the chain structure unit can undergo twisting deformation within a certain range, while keeping one dimension unchanged in three-dimensional space and allowing free rotation in the other two dimensions.

[0013] Furthermore, the PLC controller includes a display screen and a flushing button, and the display screen can display the radius, center angle, and area of ​​the pollution collection area on the lower surface of the insulator.

Device installation: Turn the insulator to be sampled upside down and install the quick collection device for the dirt on the lower surface of the insulator. Make sure that the water storage device is installed above the base of the insulator to be sampled, and the collection device is installed on the outer edge of the insulator to be sampled; S2.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings of the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0020] In order to solve the problem that the dirt on the lower surface of the insulator is difficult to collect due to the grooves, this embodiment provides a device for quickly collecting dirt on the lower surface of the insulator. Figure 1 and Figure 2As shown, the device for quickly collecting dirt on the lower surface of an insulator includes a water storage device 1, a collection device 2 and a chain structure unit 3; wherein the water storage device 1 is a container installed above the base 6 of the insulator to be sampled, and distilled water is stored in the water storage device 1, and the distilled water is used for flushing dirt; the water storage device 1 is equipped with a water flow controller and a flushing head 10, which can automatically adjust the flushing intensity and time of the distilled water according to the measurement results of the collection parameters to maximize the collection efficiency.

[0021] The collecting device 2 is a container installed on the outer edge of the insulator to be sampled, and its installation height is less than the height of the circular umbrella skirt edge of the insulator; the collecting device 2 is open at the top, and a sealable cover is installed at the top opening to prevent the leakage of dirt. The collecting device 2 is provided with a water outlet at the bottom, which can be connected to the external container pipeline through the water outlet, so that the collected dirt can be automatically transmitted to the external container, so as to detect and analyze the dirt components and content. A PLC controller connected to the water flow controller is installed outside the collecting device 2; the PLC controller includes a display screen 8; the collecting device 2 can cooperate with the chain structure unit 3, display the radius and center angle of the dirt collection area on the lower surface of the insulator through the display screen 8, and calculate the collection area of ​​the dirt collection area on the lower surface of the insulator through a formula. The PLC controller also includes a flushing button 9. Based on the collection area of ​​the dirt collection area on the lower surface of the insulator, the PLC controller can adjust the flushing intensity and time of the distilled water on the dirt collection area on the lower surface of the insulator through the water flow controller after starting the flushing button 9.

[0022] Furthermore, considering the installation and fixation of the water storage device 1 and the collection device 2, as shown in FIG. Figure 1 and Figure 2 As shown, in this embodiment, the water storage device 1 is installed above the insulator base 6 to be sampled through the first buckle 4 and the first pillar 5; one end of the first pillar 5 is in contact with the outer edge of the insulator to be sampled, and the other end is detachably installed on the insulator base 6 through the first buckle 4, and the bottom of the water storage device 1 is fixedly installed on the first pillar 5 and close to the insulator base 6. The collecting device 2 in this embodiment is installed on the outer edge of the insulator to be sampled through the second buckle 11 and the second pillar 12; one end of the second pillar 12 is fixedly connected to the bottom of the collecting device 2, and the other end is detachably installed on the insulator iron cap 7 through the second buckle 11.

[0023] like Figure 1 and Figure 2As shown, the chain structure unit 3 in this embodiment is divided into two groups, and the two groups of chain structure units 3 are arranged in a V shape between the umbrella edge and the iron cap of the insulator, and the end points of the V shape are close to the iron cap 7 of the insulator. The opening of the V shape extends to both sides of the top opening of the collection device 2, forming a pollution collection area on the lower surface of the insulator. The chain structure unit 3 is a flexible body with excellent adaptability. It can make its bottom fit the high and low undulating structure of the lower surface of the insulator through its own flexible deformation without damaging the surface of the insulator. The chain structure unit 3 can be twisted and deformed within a certain range, while keeping one dimension unchanged in three-dimensional space, and allowing free rotation in the other two dimensions.

[0024] Each chain structure unit 3 is provided with an angle and length scale for reading the radius and center angle parameters of the pollution collection area on the lower surface of the insulator, and inputting the radius and center angle parameters of the pollution collection area on the lower surface of the insulator into the PLC controller to measure and calculate the collection area on the surface of the insulator, and displaying the radius and center angle of the collection area and the calculated collection area on the display screen 8 of the PLC controller. Since the lower surface of the insulator is an undulating structure, it is impossible to accurately obtain its pollution collection area by conventional calculation methods, but by utilizing the deformation ability of the chain structure unit 3, the pollution collection area can be equivalent to a sector area, and the value read by the length scale can be regarded as the radius length value of the sector, so as to accurately calculate the collection area on the surface of the insulator.

[0025] In addition, when the chain structure unit 3 twists and deforms, the flow direction and coverage range of the distilled water in the water storage device 1 can be accurately controlled. Most of the distilled water in the water storage device 1 will flow in the direction along the chain structure, accurately flushing the dirty parts that need to be collected on the surface of the insulator, so as to save collection time and improve collection efficiency.

[0026] In summary, the present embodiment adopts a torsionally deformable chain structure unit 3, which fits the undulating structure of the lower surface of the insulator without damaging the insulator, and opens the water storage device 1 to drain distilled water, flushing the dirt on the surface of the insulator into the collection device 2, so as to conveniently and efficiently collect the dirt on the lower surface of the insulator. The insulator lower surface dirt rapid collection device combines the water storage device 1, the collection device 2 and the well-adaptable chain structure unit 3, with the angle and length scales, to ensure the accurate measurement and recording of data, and to further collect dirt for component analysis and insulator performance evaluation, and improve reliability.

[0027] Based on the above-mentioned device for quickly collecting contamination on the lower surface of an insulator, this embodiment further provides a method for quickly collecting contamination on the lower surface of an insulator, comprising the following steps: S1. Device installation: Invert the insulator to be sampled and install the quick collection device for the dirt on the lower surface of the insulator. Ensure that the water storage device 1 is installed above the base 6 of the insulator to be sampled through the first buckle 4 and the first pillar 5, and ensure that the collection device 2 is installed on the outer edge of the insulator to be sampled through the second buckle 11 and the second pillar 12.

[0028] S2. Adjustment of the chain structure unit 3: Two groups of chain structure units 3 are arranged in a V shape between the umbrella edge and the iron cap of the insulator. The angles of the two groups of chain structure units 3 are adjusted to fit the ups and downs structure of the lower surface of the insulator. The lower surface of the chain structure unit 3 coincides with the curve of the umbrella skirt edge of the insulator; at the same time, the end points of the V shape are close to the insulator iron cap 7, and the opening of the V shape extends to both sides of the top opening of the collection device 2, forming a pollution collection area on the lower surface of the insulator.

[0029] S3. Calculate the collection area: The output of the angle and length scale display on the two sets of chain structure units 3 is input to the PLC controller. The PLC controller can obtain the collection area according to the angle and length of the two sets of chain structure units 3, thereby adjusting the flushing intensity and time of the contamination collection area on the lower surface of the insulator by the distilled water through the water flow controller; The area of ​​the pollution collection area on the lower surface of the insulator is calculated by the following formula:

[0030] Wherein, S is the collection area; n is the angle scale reading on the chain structure unit 3; and R is the length scale reading of the chain structure unit 3.

[0031] S4. Preliminary dirt scraping: Use a wooden scraper to scrape the easily scraped dirt from between the metal strips into the collection device 2. This step helps to reduce the amount of distilled water used and improve the collection efficiency. Use a wooden scraper to gently scrape the loose dirt on the surface of the insulator. Collect the scraped dirt into the collection device 2 to prepare for subsequent flushing.

[0032] S5. Pollution flushing: Press the flushing button 9 of the PLC controller to control the flushing head 10 to rotate and first remove the blocky pollutants and reduce the adhesion and compactness of the gray pollutants. Then, by opening the water flow controller of the water storage device 1, distilled water is used to flush the residual pollutants in the pollutant collection area on the lower surface of the insulator according to the flushing intensity and time. The distilled water flows along the surface of the insulator through the guidance of the chain structure unit 3 to flush the residual pollutants.

[0033] S6. Collection and treatment of contaminants: The flushed liquid flows into the collection device 2 along the insulator sheet to ensure that the contaminants are effectively collected until the contaminants on the insulators to be sampled are thoroughly flushed clean; after the collection is completed, the collected contaminants are introduced into an external container through the collection device 2 connecting pipeline.

[0034] Through the above-mentioned method for rapid sampling of contamination on the lower surface of insulators, the contamination on the lower surface of insulators can be collected efficiently, accurately, environmentally friendly and easy to operate, while reducing resource waste and environmental burden, so that the stability and safety of the power system will be further improved, providing a strong guarantee for the long-term operation of power equipment.
