[0001] The present invention relates to the technical field of power equipment sampling, and specifically to a device for obtaining on-site contamination degree of substation equipment. Background Art

[0002] The device for obtaining on-site contamination degree of substation equipment usually consists of a collection frame, a collection rack, a support assembly, a telescopic device and other parts.

[0003] The patent with the patent publication number CN205580790U relates to a device for obtaining on-site contamination degree of substation equipment, including an inverted L-shaped mounting rack, a first directional wheel, a second directional wheel, a hand winch with a brake and a string of suspension porcelain insulators; if the suspension height of the string of suspension porcelain insulators needs to be lowered as required, operate the hand winch with a brake, open the brake part, turn the winch with a handle, and when it is lowered to the required height, lock the brake part. The tester collects the contaminants on the outer surface of the string of suspension porcelain insulators according to the method specified by the national standard, so as to complete the on-site collection operation of the contaminated sampling solution in the measurement of the grid contamination degree, and solves the problems in the measurement of the grid contamination degree, such as fixing the height of the reference insulator string as required according to the national standard and collecting the contaminated solution on-site. Due to the high-altitude operation, it is very unsafe for the tester and the contaminated cleaning solution is easy to be lost, resulting in incomplete collection of the contaminated solution. This device is simple to manufacture, convenient to operate, low in price, safe and reliable.

[0004] In the above patent, by turning the winch with a handle, when it is lowered to the required height, lock the brake part. The tester collects the contaminants on the outer surface of the string of suspension porcelain insulators according to the method specified by the national standard, so as to complete the on-site collection operation of the contaminated sampling solution in the measurement of the grid contamination degree. However, it is difficult to prevent the obtained sample from falling during the recovery process. If the sample falls, it will lead to incomplete collection of the sample, thus affecting the accuracy of the data, and further resulting in the inability to fully reflect the true situation of the contamination on the equipment surface. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a device for obtaining on-site contamination degree of substation equipment, which solves the problems raised in the above background art.

[0006] To achieve the above object, the present invention is realized by the following technical solutions: A device for obtaining on-site pollution degree of substation equipment, including a substation frame and a telescopic device, further includes an acquisition component. An insulator body is arranged on the top of the substation frame. An acquisition frame is fixedly installed at the top of the telescopic device. A servo motor is fixedly installed on the top of the acquisition frame. A lead screw is fixedly installed at the output end of the servo motor.

An anti-falling plate is fixedly installed at the rear side of the L-shaped plate. An anti-falling spring is arranged between the L-shaped plate and the anti-falling hole. An acquisition hole is opened at the bottom of the acquisition frame. The movement and reset of the L-shaped plate drive the movement and reset of the anti-falling plate. The reciprocating movement of the anti-falling plate pushes the sample at the bottom of the acquisition frame.

[0007] According to the above technical solution, the acquisition ring contacts the insulator body. The L-shaped plate penetrates the inner and outer walls of the acquisition frame. The top of the acquisition ring is set as an inclined surface. The reciprocating movement of the acquisition ring scrapes and collects the dirt on the surface of the insulator body.

[0008] According to the above technical solution, the side of the anti-falling plate close to the insulator body is set as an inclined surface. A convex block is fixedly installed at the bottom of the acquisition ring. The downward movement of the convex block impacts the inner wall of the acquisition frame to generate vibration. The anti-falling plate contacts the bottom of the inner wall of the acquisition frame.

[0009] According to the above technical solution, a dissolving component for improving the sampling acquisition efficiency is arranged on the top of the acquisition frame. Support components are arranged on the upper and lower walls of the fixed ring. The dissolving component includes a processing frame, a load-bearing rod, a U-shaped plate, a sealing frame, an arc-shaped hole and a liquid spraying pipe. The dissolving agent inside the sealing frame is sprayed onto the top of the acquisition ring through the liquid spraying pipe. The processing frame is fixedly installed on the top of the acquisition frame. The load-bearing rod is fixedly installed at the bottom of the inner wall of the processing frame.

[0010] According to the above technical solution, an arc-shaped rod is fixedly installed on the left side of the U-shaped plate. The arc-shaped rod is elastic. A buffer rod is fixedly installed on the inner wall of the processing frame. The arc-shaped rod contacts the buffer rod. The arc-shaped rod slowly deforms so that the U-shaped plate can only slowly move downward and reset.

[0011] According to the above technical solution, a first spring is arranged between the U-shaped plate and the treatment frame. The U-shaped plate can be driven to reset by the first spring. A cross rubber valve is arranged inside the liquid spraying pipe. The U-shaped plate penetrates through the bottom of the treatment frame. A first rubber ring is arranged between the U-shaped plate and the treatment frame. The sealing performance between the U-shaped plate and the treatment frame can be improved through the first rubber ring. A second rubber ring is arranged between the U-shaped plate and the sealing frame. The sealing performance between the U-shaped plate and the sealing frame can be improved through the second rubber ring.

[0012] According to the above technical solution, the support assembly includes a linkage pipe, a linkage plate, a linkage rod, a support plate, a support rod and a support spring. The support rod moves away from the contact with the insulator body, and the support rod reciprocates to intermittently support the acquisition frame.

There is liquid inside the linkage pipe.

[0013] According to the above technical solution, the linkage rod penetrates through the top of the treatment frame and contacts the top of the U-shaped plate. A third rubber ring is arranged between the linkage pipe and the linkage plate. The sealing performance between the linkage pipe and the linkage plate can be increased through the third rubber ring. A fourth rubber ring is arranged between the linkage pipe and the support plate. The sealing performance between the linkage pipe and the support plate can be increased through the fourth rubber ring.

[0014] The present invention provides a device for obtaining the on-site pollution degree of substation equipment. It has the following beneficial effects:

[0015] (1) For the device for obtaining the on-site pollution degree of substation equipment, by vibrating the acquisition ring, the sampling effect of the acquisition ring is improved. Vibration can help loosen and collect the pollutants adhering to the surface of the insulator body, avoiding sampling failure due to the tight adhesion of pollutants. By the reciprocating movement of the anti-falling plate, the samples at the bottom of the acquisition frame are pushed. The samples at the bottom of the acquisition frame are pushed by the anti-falling plate to prevent the samples from falling through the acquisition holes during the recovery process. The reciprocating push of the anti-falling plate effectively prevents the samples from falling off or being lost during the recovery process, thus ensuring the accuracy and reliability of sample acquisition and sampling.

[0016] (2) For the device for obtaining the on-site pollution degree of substation equipment, by the reciprocating movement of the acquisition ring, the dirt on the surface of the insulator body is scraped and collected. The scraped dirt slides down to the bottom of the acquisition frame under the action of its own gravity. Through the reciprocating scraping, the accumulation deviation of pollutants can be effectively reduced, and more areas can be effectively covered, ensuring the representativeness of the collected samples.

[0017] (3)For the on-site pollution degree acquisition device of this power transformation equipment, the quantitative solvent inside the sealing frame is sprayed onto the top of the acquisition ring through the liquid spraying pipe. The solvent sprayed on the top of the acquisition ring is evenly smeared on the surface of the insulator body by the acquisition ring. The dirt is difficult to scrape off due to its hardness or adhesiveness. By using the solvent quantitatively, the dirt can be softened or decomposed, so as to ensure that the collected sample can truly reflect the pollution degree of the insulator.

[0018] (4)For the on-site pollution degree acquisition device of this power transformation equipment, the arc-shaped rod slowly deforms under the reaction force of the extrusion buffer rod. The slow deformation of the arc-shaped rod makes the U-shaped plate can only move downward slowly to reset. By slowly moving the U-shaped plate to extrude the solvent, the contact between the solvent and the dirt can be made more uniform, so as to achieve the best dissolution effect and further improve the efficiency of obtaining the sampling sample.

[0019] (5)For the on-site pollution degree acquisition device of this power transformation equipment, the support rod moves away from the contact with the insulator body. The support rod reciprocates to intermittently support the acquisition frame. The intermittent support of the support rod can ensure that the acquisition frame remains stable, avoiding the inclination or shaking of the acquisition frame caused by external environmental factors, and then ensuring the accuracy and consistency of the dirt collection process.

Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1-6 , an embodiment of the present invention is: a device for obtaining the pollution degree on-site of substation equipment, including a substation frame 1 and a telescopic device 3, and further including an acquisition component. An insulator body 2 is arranged on the top of the substation frame 1. The telescopic device 3 is fixedly installed with an acquisition frame 4 at the top. The acquisition frame 4 is fixedly installed with a servo motor 5 at the top. The output end of the servo motor 5 is fixedly installed with a lead screw 6. An acquisition ring 7 is slidably installed on the inner wall of the acquisition frame 4. The acquisition ring 7 is threadedly connected with the lead screw 6. A fixed ring 13 is fixedly installed on the circumferential surface of the acquisition frame 4. An anti-falling hole 8 is opened at the top of the fixed ring 13. An anti-falling rod 9 is fixedly installed on the inner wall of the anti-falling hole 8. An L-shaped plate 10 is slidably installed on the circumferential surface of the anti-falling rod 9. An anti-falling plate 11 is fixedly installed at the rear side of the L-shaped plate 10. An anti-falling spring 12 is arranged between the L-shaped plate 10 and the anti-falling hole 8. An acquisition hole is opened at the bottom of the acquisition frame 4. The reciprocating push of the anti-falling plate 11 effectively prevents the sample from falling off or being lost during the recovery process, thereby ensuring the accuracy and reliability of sample acquisition and sampling.

[0030] The acquisition ring 7 contacts the insulator body 2. The L-shaped plate 10 penetrates through the inner and outer walls of the acquisition frame 4. The top of the acquisition ring 7 is set as an inclined surface. The acquisition ring 7 reciprocates to scrape and collect the dirt on the surface of the insulator body 2. The reciprocating scraping can effectively reduce the accumulation deviation of pollutants, and further effectively cover more areas to ensure that the collected samples are representative.

[0031] The side of the anti-drop plate 11 close to the insulator body 2 is set as an inclined surface, and a protrusion is fixedly installed at the bottom of the acquisition ring 7. The protrusion moves downward and hits the inner wall of the acquisition frame 4 to generate vibration. The vibration can help loosen and collect pollutants adhered to the surface of the insulator body 2, avoiding inadequate sampling due to the tight adhesion of pollutants. The anti-drop plate 11 is in contact with the bottom of the inner wall of the acquisition frame 4.

[0032] When this embodiment is working: the acquisition frame 4 is sent to the top of the insulator body 2 by the telescopic device 3. After the acquisition frame 4 is aligned with the insulator body 2, the telescopic device 3 drives the acquisition frame 4 to move downward so that the acquisition hole contacts the insulator body 2. At the same time, the servo motor 5 drives the screw rod 6 to rotate, and the rotation of the screw rod 6 drives the acquisition ring 7 to move downward. When the acquisition ring 7 moves downward, it drives the protrusion to move downward. The protrusion moves downward and hits the inner wall of the acquisition frame 4 to generate vibration. The vibration of the protrusion drives the acquisition ring 7 to vibrate. The vibration of the acquisition ring 7 thereby improves the sampling effect of the acquisition ring 7. When the acquisition ring 7 moves downward to the lowest position, the servo motor 5 drives the screw rod 6 to rotate in the opposite direction. The screw rod 6 rotates in the opposite direction to drive the acquisition ring 7 to move upward. The acquisition ring 7 reciprocates to scrape and collect the dirt on the surface of the insulator body 2. The scraped dirt slides downward to the bottom of the acquisition frame 4 under the action of its own gravity. When the acquisition ring 7 moves downward, it will contact the inclined surface of the anti-fall plate 11. The acquisition ring 7 contacts the inclined surface of the anti-fall plate 11 and squeezes the anti-fall plate 11. The anti-fall plate 11 is squeezed by the acquisition ring 7 and moves in the direction away from the insulator body 2. The anti-fall plate 11 moves in the direction away from the insulator body 2 and drives the L-shaped plate 10 to move. The movement of the L-shaped plate 10 squeezes the anti-fall spring 12. The anti-fall spring 12 is squeezed by the L-shaped plate 10 and deforms and accumulates force. After the acquisition ring 7 moves upward and breaks away from the contact with the anti-fall plate 11, the L-shaped plate 10 moves and resets in the direction close to the insulator body 2 under the action of the elastic force of the anti-fall spring 12. The L-shaped plate 10 moves and resets, driving the anti-fall plate 11 to move and reset. The anti-fall plate 11 moves back and forth to push the sample at the bottom of the acquisition frame 4. The sample at the bottom of the acquisition frame 4 is pushed by the anti-fall plate 11 to prevent the sample from falling through the acquisition hole during the recovery process.

[0033] See also Figures 1-7, on the basis of the above embodiments, in another embodiment of the present invention, a dissolving component for improving the sampling acquisition efficiency is provided at the top of the acquisition frame 4, and support components are provided on the upper and lower walls of the fixing ring 13.

A dissolving agent is provided inside the sealing frame 144. By quantitatively using the dissolving agent, the dirt can be softened or decomposed, so as to ensure that the collected sample can truly reflect the pollution degree of the insulator body 2.

[0034] An arc-shaped rod 147 is fixedly installed on the left side of the U-shaped plate 143. The arc-shaped rod 147 has elasticity. A buffer rod 148 is fixedly installed on the inner wall of the processing frame 141. The arc-shaped rod 147 contacts the buffer rod 148. The arc-shaped rod 147 slowly deforms, so that the U-shaped plate 143 can only slowly move downward and reset. By slowly moving the U-shaped plate 143 to squeeze the dissolving agent, the dissolving agent can contact the dirt more evenly, so as to achieve the best dissolving effect and further improve the efficiency of obtaining the sampling sample.

[0035] A first spring is provided between the U-shaped plate 143 and the processing frame 141. The first spring can drive the U-shaped plate 143 to reset. A cross-shaped rubber valve is provided inside the liquid spraying pipe 146. The U-shaped plate 143 penetrates through the bottom of the processing frame 141. A first rubber ring is provided between the U-shaped plate 143 and the processing frame 141. The first rubber ring can improve the sealing performance between the U-shaped plate 143 and the processing frame 141. A second rubber ring is provided between the U-shaped plate 143 and the sealing frame 144.

[0036] The support component includes a linkage pipe 151, a linkage plate 152, a linkage rod 153, a support plate 154, a support rod 155, and a support spring 156.

The linkage rod 153 fixedly penetrates through the upper and lower walls of the linkage plate 152. The support plate 154 is slidably installed on the inner wall of the linkage pipe 151. The support rod 155 fixedly penetrates through the left and right walls of the support plate 154. The support spring 156 is provided between the support plate 154 and the linkage pipe 151. Liquid is provided inside the linkage pipe 151. The intermittent support of the support rod 155 can ensure that the acquisition frame 4 remains stable, avoid the inclination or shaking of the acquisition frame 4 due to external environmental factors, and further ensure the accuracy and consistency of the dirt collection and acquisition process.

[0037] The linkage rod 153 passes through the top of the processing frame 141, and the linkage rod 153 contacts the top of the U-shaped plate 143. A No. 3 rubber ring is arranged between the linkage tube 151 and the linkage plate 152, and the No. 3 rubber ring can increase the sealing between the linkage tube 151 and the linkage plate 152. A No. 4 rubber ring is arranged between the linkage tube 151 and the support plate 154, and the No. 4 rubber ring can increase the sealing between the linkage tube 151 and the support plate 154.

[0038] When the present embodiment is working, the acquisition ring 7 moves upward to contact with the U-shaped plate 143 and squeeze the U-shaped plate 143. The U-shaped plate 143 is squeezed upward by the acquisition ring 7. The U-shaped plate 143 moves upward to break away from the contact with the arc hole 145 and releases the seal on the bottom of the sealing frame 144. After the seal on the bottom of the sealing frame 144 is released, the dissolving agent inside the processing frame 141 enters the bottom of the sealing frame 144 through the arc hole 145. After the acquisition ring 7 moves downward to break away from the contact with the U-shaped plate 143, the U-shaped plate 143 moves downward under the elastic force of the first spring. The U-shaped plate 143 moves downward to seal the bottom of the sealing frame 144 and squeeze the dissolving agent inside the sealing frame 144. The dissolving agent inside the sealing frame 144 is squeezed by the U-shaped plate 143 and enters the inside of the liquid spraying pipe 146, and then The solvent entering the liquid spraying pipe 146 squeezes the cross rubber valve, and the cross rubber valve is squeezed by the solvent entering the liquid spraying pipe 146 to be deformed. The cross rubber valve is deformed to release the seal of the liquid spraying pipe 146. After the seal of the liquid spraying pipe 146 is released, the solvent in the sealing frame 144 is sprayed to the top of the acquisition ring 7 through the liquid spraying pipe 146. The solvent sprayed on the top of the acquisition ring 7 is evenly smeared on the surface of the insulator body 2 by the acquisition ring 7. At the same time, the U-shaped plate 143 moves downward to drive the arc rod 147 to move downward. The arc rod 147 moves downward and contacts the buffer rod 148 and squeezes the buffer rod 148. The arc rod 147 is slowly deformed by the reaction force of squeezing the buffer rod 148. The arc rod 147 slowly deforms so that the U-shaped plate 143 can only move slowly downward to reset.

[0039] The U-shaped plate 143 moves upward to contact the linkage rod 153 and squeeze the linkage rod 153. The linkage rod 153 moves upward under the squeeze of the U-shaped plate 143. The upward movement of the linkage rod 153 drives the linkage plate 152 to move upward. The upward movement of the linkage plate 152 squeezes the liquid inside the linkage tube 151. The liquid inside the linkage tube 151 is squeezed by the linkage plate 152 and then squeezes the support plate 154. The support plate 154 moves in the direction close to the insulator body 2 under the squeeze of the liquid inside the linkage tube 151. The movement of the support plate 154 in the direction close to the insulator body 2 pulls the support spring 156. The support spring 156 deforms and stores energy under the pull of the support plate 154. At the same time, the movement of the support plate 154 in the direction close to the insulator body 2 drives the support rod 155 to move and contact the insulator body 2. After the U-shaped plate 143 moves downward to disengage from the linkage rod 153, the support plate 154 moves in the direction away from the insulator body 2 under the elastic force of the support spring 156. The movement of the support plate 154 in the direction away from the insulator body 2 drives the support rod 155 to move. The support rod 155 moves away from the contact with the insulator body 2. The reciprocating movement of the support rod 155 intermittently supports the acquisition frame 4.
