Description
Technical Field
[0001] The utility model relates to the field of porcelain insulator coating detection, in particular to a device for detecting the performance of an anti-pollution coating on a porcelain insulator. Background Art
[0002] Porcelain insulators are components used in power systems to support and insulate power lines. They are usually made of porcelain materials. Its main function is to isolate the power line from the ground or other conductive objects to prevent current leakage and ensure the safety and stability of power transmission. Porcelain insulators have high insulation performance and are resistant to high temperature and corrosion. They are commonly used in high-voltage power transmission lines. In some areas, especially industrial areas, coastal areas or places with air pollution, dirt, dust or salt are likely to accumulate on the surface of the insulator. These dirt will reduce the insulation performance of the insulator, increase the leakage current, and even cause the insulator to break down or power equipment failure. The anti-pollution coating can effectively reduce the impact of these dirt on the porcelain insulator.
[0003] Although the current technology has many advantages, its disadvantages are that there is currently no device for directly detecting the anti-pollution coating of porcelain insulators. Most detections are directly sent to the site and roughly judged by observation. Since the detection is carried out externally, the detection results will be interfered by a large number of external factors, greatly affecting the accuracy of the detection results. In addition, the traditional detection method can only perform single detection and cannot detect the hydrophobic, dust-proof and salt spray resistance performance of the anti-pollution coating of porcelain insulators. It cannot perform diversified detection, reducing the overall detection quality of the anti-pollution coating of porcelain insulators. Moreover, during the detection, since the contact area of the porcelain insulator with the ground is very small, when it is directly placed in the device, it cannot be stably placed and cannot be firmly clamped to cope with the changes in the simulated environment, reducing the practicability of the device for detecting the performance of the anti-pollution coating of porcelain insulators.

[0020] Compared with the prior art, the advantages and positive effects of the present utility model are:
[0021] 1. For this utility model, first place multiple porcelain insulator samples in the main body of the independent testing room. Among them, two porcelain insulator samples have a hydrophobic material coating on their surfaces, and the other has no coating on its surface. Then remove multiple watering buckets, unscrew the bottle caps on the tops of the watering buckets, fill the watering buckets with water, and then tighten the bottle caps. Hang the watering buckets evenly on the hooks through the placement hooks, and use the multiple round holes at the bottoms of the watering buckets to sprinkle water to simulate the process of rain falling. At this time, the high-legged table, transparent containers, and kaolin powder are not placed in the main body of the independent testing room. Use the water in the watering buckets to spray multiple porcelain insulator samples, and then observe the inside of the main body of the independent testing room through the observation glass plate, take pictures and record, and make a judgment by comparing the surface states of the porcelain insulator samples without coating, so as to complete the detection of the hydrophobic performance in the anti-pollution coating of the insulator. After the hydrophobic performance detection is completed, place a small humidifier between the fixture components. The small humidifier is composed of a pure water bottle and a small USB umbrella humidifier. The staff pours a sufficient amount of salt water mixture into the pure water bottle, and then turns on the external power supply of the electric telescopic rod. Use the controller to start the electric telescopic rod, so that the electric telescopic rod pushes the long rack, and the long rack drives the circular gear to turn as a whole to complete the horizontal turning of the small humidifier. Then start Motor 1, use the output end of Motor 1 to drive Motor 1 to turn vertically until it turns to the required position. Subsequently, turn on the two small humidifiers. Previously, multiple porcelain insulator samples have been replaced with two porcelain insulator samples with anti-salt fog performance and one porcelain insulator sample without coating. Use the two small humidifiers to simulate the salt fog state and let the small humidifiers spray for 1 - 3 hours. Then turn off the small humidifiers and keep the inside of the main body of the independent testing room as an independent space and closed for no less than 24 hours. Then continue to use multiple watering buckets to spray multiple porcelain insulator samples, and then compare and detect the porcelain insulator samples without coating, so as to complete the detection of the anti-salt fog performance. After the detection is completed, place the transparent containers and kaolin powder on the high-legged table, and place the entire high-legged table at the required position. Then turn on the external power supply of Motor 2, use the output end of Motor 2 to drive the rotating block to perform a circular motion, and drive the swing rod to rotate through the rotating block. At this time, the hollow plate swings cyclically as the swing rod rotates, and the swing rod in the middle of the hollow plate can also swing horizontally left and right in the hollow plate. Subsequently, start the blower body, so that the blower body blows at different inclination angles for 0.For 5 - 2 hours, then turn off the blower, keep the independent detection room body as an independent space closed for no less than 24 hours, blow kaolin powder through the blower body to simulate the dust state, then use multiple watering buckets to spray multiple porcelain insulator samples again, observe and photograph the surface state of the multiple porcelain insulator samples, and at the same time make a judgment by comparing with the surface state of the porcelain insulator samples without coating.

At this time, two limiting grooves limit the sliders to prevent them from idling. The two sliders drive the two clamping plates to firmly hold the bottom of the porcelain insulator samples. At this time, multiple anti - slip pads provide anti - slip function, so as to achieve the firm clamping of the porcelain insulator samples, cope with the changes in the simulated environment, and improve the practicability of the performance detection device for the anti - pollution coating of porcelain insulators.

A sealed door 102 is connected to the other side of the outer surface of the independent detection room body 1 through a hinge.
[0035] In this embodiment, first, a plurality of porcelain insulator samples 208 are placed in the independent test room body 1. Among them, two porcelain insulator samples 208 have a hydrophobic material coating on their surfaces, and the other one has no coating on its surface. Then, a plurality of watering buckets 107 are removed, the bottle caps 105 on the tops of the watering buckets 107 are unscrewed, the watering buckets 107 are filled with water, and then the bottle caps 105 are tightened. The watering buckets 107 are evenly hung on the hooks 104 through the placement hooks 106, and water is sprinkled through the plurality of round holes at the bottoms of the watering buckets 107 to simulate the process of rain falling. At this time, the high-legged table 109, the transparent container 110, and the kaolin powder 111 are not placed in the independent test room body 1. The water in the watering buckets 107 is used to spray the plurality of porcelain insulator samples 208. Subsequently, the inside of the independent test room body 1 is observed through the observation glass plate 101, photographed and recorded, and a judgment is made by comparing the surface states of the uncoated porcelain insulator samples 208, thus completing the detection of the hydrophobic performance of the insulator anti-pollution coating. After the hydrophobic performance detection is completed, the small humidifier 119 is placed between the fixture assemblies 120. The small humidifier 119 is composed of a pure water bottle and a small USB umbrella humidifier. The staff pours a sufficient amount of salt water mixture into the pure water bottle, then turns on the external power supply of the electric telescopic rod 113, and starts the electric telescopic rod 113 by using the controller, so that the electric telescopic rod 113 pushes the long rack 114, and the long rack 114 drives the whole circular gear 115 to turn, completing the horizontal turning of the small humidifier 119. Then, the first motor 116 is started, and the output end of the first motor 116 is used to drive the first motor 116 to perform vertical turning until it turns to the required position. Subsequently, the two small humidifiers 119 are turned on. Previously, the plurality of porcelain insulator samples 208 have been replaced with two porcelain insulator samples 208 with salt spray resistance and one uncoated porcelain insulator sample 208. The two small humidifiers 119 are used to simulate the salt spray state, and the small humidifiers 119 spray for 1 - 3 hours. Then, the small humidifiers 119 are turned off, and the inside of the independent test room body 1 is kept in an independent space and closed for no less than 24 hours. Then, the plurality of watering buckets 107 are used to spray the plurality of porcelain insulator samples 208 again, and then the uncoated porcelain insulator samples 208 are detected for comparison, thus completing the detection of the salt spray resistance. After the detection is completed, the transparent container 110 and the kaolin powder 111 are placed on the high-legged table 109, and the high-legged table 109 as a whole is placed at the required position. Subsequently, the external power supply of the second motor 128 is turned on, and the output end of the second motor 128 is used to drive the rotating block 124 to perform a circular motion. The swinging rod 125 is driven to rotate by the rotating block 124. At this time, the hollow plate 123 swings cyclically as the swinging rod 125 rotates. The swinging rod 125 in the middle of the hollow plate 123 can also swing horizontally left and right in the hollow plate 123. Subsequently, the blower body 126 is started, and the blower body 126 blows at different inclination angles for 0.For 5 - 2 hours, then turn off the blower, keep the independent test room body 1 in a closed independent space for no less than 24 hours, blow kaolin powder 111 through the blower body 126 to simulate the dust state, then use multiple watering buckets 107 to spray the surfaces of multiple porcelain insulator samples 208 again, observe and photograph the surface states, and at the same time make a judgment by comparing with the surface states of the porcelain insulator samples 208 without coating. Among the multiple porcelain insulator samples 208 before, two of them have been replaced with porcelain insulator samples 208 with a dust - proof coating, and the other one is a porcelain insulator sample 208 without coating. In this way, the dust - proof performance detection is completed, so as to have a device for directly detecting the anti - pollution coating of porcelain insulators, prevent the detection results from being interfered by a large number of external factors on site, greatly ensure the accuracy of the detection results, and be able to detect the hydrophobic, dust - proof and salt - fog resistance performance of the anti - pollution coating of porcelain insulators, which is convenient for diversified detection and improves the overall detection quality of the anti - pollution coating of porcelain insulators.
[0036] Example 2, as Figures 1-8 shown, both sides of the inner wall of the groove 202 are movably connected with a bidirectional threaded rod 204. One end of the bidirectional threaded rod 204 is fixedly connected with a knob 201. Two sliders 205 are threadedly connected to the outer surface of the bidirectional threaded rod 204. Both sides of the outer surfaces of the two sliders 205 are movably embedded in the inner walls of two limiting grooves 203. The tops of the two sliders 205 are both fixedly connected with clamping plates 206. A plurality of anti - slip pads 207 are fixedly connected to the inner walls of the two clamping plates 206. A porcelain insulator sample 208 is arranged in the inner walls of the two clamping plates 206.
[0037] In this embodiment, in order to firmly clamp the multiple porcelain insulator samples 208, when the staff place the multiple porcelain insulator samples 208, first place the multiple porcelain insulator samples 208 in the two clamping plates 206 respectively, and then turn the knob 201 in sequence. Drive the bidirectional threaded rod 204 to rotate forward through the knob 201. Use the forward rotation of the bidirectional threaded rod 204 to drive the two sliders 205 to move towards the middle of the bidirectional threaded rod 204. At this time, the two limiting grooves 203 limit the sliders 205 to prevent them from idling. The two sliders 205 drive the two clamping plates 206 to firmly clamp the bottom of the porcelain insulator sample 208. At this time, the multiple anti - slip pads 207 provide anti - slip function for it, so as to firmly clamp the porcelain insulator sample 208, be used to cope with the changes of the simulated environment, and improve the practicability of the performance detection device for the anti - pollution coating of porcelain insulators.
[0038] Working principle: When in use, first place multiple porcelain insulator samples 208 in the independent test chamber body 1. Among them, two porcelain insulator samples 208 have a coating of hydrophobic material on their surfaces, and the other has no coating on its surface. Then remove multiple watering buckets 107, unscrew the bottle caps 105 on the tops of the watering buckets 107, pour water into the watering buckets 107 until full, and then tighten the bottle caps 105. Hang the watering buckets 107 evenly on the hooks 104 through the placement hooks 106, and use the multiple round holes at the bottoms of the watering buckets 107 to sprinkle water to simulate the process of rain falling. At this time, the high-legged table 109, the transparent container 110, and the kaolin powder 111 are not placed in the independent test chamber body 1. Use the water in the watering buckets 107 to spray multiple porcelain insulator samples 208. Subsequently, observe the inside of the independent test chamber body 1 through the observation glass plate 101, take pictures and records, and make a judgment by comparing the surface states of the porcelain insulator samples 208 without coating, so as to complete the detection of the hydrophobic performance in the insulator anti-fouling coating. After the hydrophobic performance detection is completed, place the small humidifier 119 between the fixture assemblies 120. The small humidifier 119 is composed of a pure water bottle and a small USB umbrella humidifier. The staff pours a sufficient amount of salt water mixture into the pure water bottle, then turns on the external power supply of the electric telescopic rod 113, and uses the controller to start the electric telescopic rod 113, so that the electric telescopic rod 113 pushes the long rack 114, and the long rack 114 drives the whole circular gear 115 to turn, completing the horizontal turning of the small humidifier 119. Then start the first motor 116, and use the output end of the first motor 116 to drive the first motor 116 to turn vertically until it turns to the required position. Subsequently, turn on the two small humidifiers 119. Previously, multiple porcelain insulator samples 208 have been replaced with two porcelain insulator samples 208 with salt spray resistance and one porcelain insulator sample 208 without coating. Use the two small humidifiers 119 to simulate the salt spray state, and let the small humidifiers 119 spray for 1 - 3 hours. Then turn off the small humidifiers 119, keep the inside of the independent test chamber body 1 as an independent space and close it for no less than 24 hours. Then continue to spray multiple porcelain insulator samples 208 with multiple watering buckets 107, and then detect by comparing the porcelain insulator samples 208 without coating, so as to complete the detection of the salt spray resistance. After the detection is completed, place the transparent container 110 and the kaolin powder 111 on the high-legged table 109, and place the whole high-legged table 109 at the required position. Subsequently, turn on the external power supply of the second motor 128, and use the output end of the second motor 128 to drive the rotating block 124 to perform a circular motion. Drive the swing rod 125 to rotate through the rotating block 124. At this time, the hollow plate 123 swings cyclically as the swing rod 125 rotates. The swing rod 125 in the middle of the hollow plate 123 can also swing horizontally left and right in the hollow plate 123. Subsequently, start the blower body 126, and let the blower body 126 blow at different inclined angles for 0.For 5 - 2 hours, then turn off the blower, and keep the independent test chamber body 1 in a closed independent space for no less than 24 hours. Blow kaolin powder 111 through the blower body 126 to simulate the dust state. Then, use multiple watering buckets 107 to spray the surfaces of multiple porcelain insulator samples 208 again, observe and photograph the surface states, and make a judgment by comparing with the surface states of the uncoated porcelain insulator samples 208. Among the multiple porcelain insulator samples 208 before, two of them have been replaced with porcelain insulator samples 208 with a dust - proof coating, and the other one is an uncoated porcelain insulator sample 208. In this way, the dust - proof performance detection is completed, so as to have a device for directly detecting the anti - pollution coating of porcelain insulators, preventing the detection results from being interfered by a large number of external factors on - site, greatly ensuring the accuracy of the detection results, and being able to detect the hydrophobic, dust - proof and salt - fog resistance performance of the anti - pollution coating of porcelain insulators, facilitating diversified detection, improving the overall detection quality of the anti - pollution coating of porcelain insulators. And in order to firmly clamp multiple porcelain insulator samples 208, when the staff place multiple porcelain insulator samples 208, first place multiple porcelain insulator samples 208 in two clamping plates 206 respectively, and then turn the knob 201 in sequence. Drive the bidirectional threaded rod 204 to rotate forward through the knob 201. Use the forward rotation of the bidirectional threaded rod 204 to drive two sliders 205 to move towards the middle of the bidirectional threaded rod 204. At this time, two limiting grooves 203 limit the sliders 205 to prevent them from idling. The two sliders 205 drive the two clamping plates 206 to firmly clamp the bottom of the porcelain insulator sample 208. At this time, multiple anti - slip pads 207 provide anti - slip function, so as to firmly clamp the porcelain insulator sample 208, cope with the changes in the simulated environment, and improve the practicability of the performance detection device for the anti - pollution coating of porcelain insulators.
