Description

Technical Field

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

[0002] The on-site pollution degree acquisition device for substation equipment usually consists of a collection frame, a collection rack, a supporting component and a telescopic device.

[0003] The patent with the patent announcement number CN205580790U relates to a device for obtaining the on-site pollution degree of substation equipment, including an inverted L-shaped mounting frame, a first directional wheel, a second directional wheel, a hand-cranked winch with a brake, and a suspended porcelain insulator string; if the suspension height of the suspended porcelain insulator string needs to be lowered as needed, the hand-cranked winch with a brake is operated to open the brake part, and the winch is rotated by a handle. When it is lowered to the required height, the brake part is locked, and the test personnel collect the dirt on the outer surface of the suspended porcelain insulator string according to the method specified in the national standard, thereby completing the on-site collection of the pollution sampling solution in the measurement of the pollution degree of the power grid, solving the problems of fixing the height of the reference insulator string as needed and sampling and collecting the pollution solution on site according to the requirements of the national standard in the measurement of the pollution degree of the power grid, and the problems of the test personnel working very unsafely due to high-altitude operation and the pollution cleaning liquid being easily lost, resulting in incomplete collection of the pollution solution. The device is simple to manufacture, easy to operate, low in price, safe and reliable.

[0014] The present invention provides a device for obtaining the on-site pollution level of substation equipment. It has the following beneficial effects: (1) The on-site pollution degree acquisition device of the substation equipment improves the sampling effect of the acquisition ring by vibrating the acquisition ring. Vibration can help loosen and collect pollutants adhering to the surface of the insulator body, avoiding inadequate sampling due to the tight adhesion of pollutants. The anti-drop plate reciprocates to push the sample at the bottom of the acquisition frame. The sample at the bottom of the acquisition frame is pushed by the anti-drop plate to prevent the sample from falling through the acquisition hole during the recovery process. The reciprocating push of the anti-drop plate 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.

[0015] (2) The on-site pollution degree acquisition device of the substation equipment scrapes and collects the dirt on the surface of the insulator body through the reciprocating movement of the acquisition ring. The scraped dirt slides down to the bottom of the acquisition frame under the action of its own gravity. The reciprocating scraping can effectively reduce the accumulation deviation of pollutants, thereby effectively covering more areas and ensuring that the collected samples are representative.

[0016] (3) The on-site contamination acquisition device of the substation equipment uses a quantitative solvent inside the sealing frame to spray to the top of the acquisition ring through a liquid spray pipe. The solvent sprayed on the top of the acquisition ring is evenly spread on the surface of the insulator body by the acquisition ring. The contaminants are difficult to scrape off and acquire due to their hardness or adhesion. The contaminants can be softened or decomposed by quantitative use of the solvent, thereby ensuring that the collected samples can truly reflect the degree of contamination of the insulator.

[0017] (4) The on-site contamination degree acquisition device for the substation equipment is designed to slowly deform the arc rod under the reaction force of the squeeze buffer rod. The arc rod slowly deforms so that the U-shaped plate can only slowly move downward to reset. The U-shaped plate slowly moves to squeeze the dissolving agent, which can make the contact between the dissolving agent and the contaminants more uniform, thereby achieving the best dissolving effect and further improving the efficiency of obtaining sampling samples.

[0018] (5) The on-site pollution degree acquisition device of the substation equipment moves the support rod to break away from the contact with the insulator body, and 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 and avoids tilting or shaking of the acquisition frame due to external environmental factors, thereby ensuring the accuracy and consistency of the pollution collection process.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in 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. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-Figure 6 An embodiment of the present invention is: a device for obtaining the on-site pollution degree of substation equipment, comprising a substation frame 1 and a telescopic device 3, and also comprising an obtaining component, an insulator body 2 is arranged on the top of the substation frame 1, an obtaining frame 4 is fixedly installed on the top of the telescopic device 3, a servo motor 5 is fixedly installed on the top of the obtaining frame 4, a screw rod 6 is fixedly installed on the output end of the servo motor 5, an obtaining ring 7 is slidably installed on the inner wall of the obtaining frame 4, the obtaining ring 7 is threadedly connected with the screw rod 6, a fixing ring 13 is fixedly installed on the circumferential surface of the obtaining frame 4, an anti-drop hole 8 is opened on the top of the fixing ring 13, an anti-drop rod 9 is fixedly installed on the inner wall of the anti-drop hole 8, an L-shaped plate 10 is slidably installed on the circumferential surface of the anti-drop rod 9, an anti-drop plate 11 is fixedly installed on the rear side of the L-shaped plate 10, an anti-drop spring 12 is arranged between the L-shaped plate 10 and the anti-drop hole 8, an obtaining hole is opened at the bottom of the obtaining frame 4, and the reciprocating push of the anti-drop 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 sampling.

[0023] The acquisition ring 7 is in contact with the insulator body 2, the L-shaped plate 10 passes through the inner and outer walls of the acquisition frame 4, the top of the acquisition ring 7 is set as an inclined surface, and the acquisition ring 7 moves back and forth 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, thereby effectively covering more areas and ensuring that the collected samples are representative.

[0024] 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.

[0025] 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.

[0026] See also Figure 1-Figure 7On the basis of the above embodiment, in another embodiment of the present invention, a dissolving component for improving the sampling acquisition efficiency is provided on the top of the acquisition frame 4, and a supporting component is provided on the upper and lower walls of the fixed ring 13. The dissolving component includes a processing frame 141, a load-bearing rod 142, a U-shaped plate 143, a sealing frame 144, an arc-shaped hole 145 and a liquid spraying pipe 146.

The pollutants can be softened or decomposed by quantitative use of the dissolving agent, thereby ensuring that the collected samples can truly reflect the degree of pollution of the insulator body 2.

[0027] A curved rod 147 is fixedly installed on the left side of the U-shaped plate 143, and the curved rod 147 is elastic. A buffer rod 148 is fixedly installed on the inner wall of the processing frame 141. The curved rod 147 contacts the buffer rod 148, and the curved rod 147 slowly deforms so that the U-shaped plate 143 can only move slowly downward to reset. By slowly moving the U-shaped plate 143 to squeeze the dissolving agent, the dissolving agent can be in contact with the dirt more evenly, thereby achieving the best dissolving effect and further improving the efficiency of obtaining sampling samples.

[0028] A No. 1 spring is arranged between the U-shaped plate 143 and the processing frame 141, and the No. 1 spring can drive the U-shaped plate 143 to reset. A cross rubber valve is arranged inside the liquid spray pipe 146. The U-shaped plate 143 passes through the bottom of the processing frame 141. A No. 1 rubber ring is arranged between the U-shaped plate 143 and the processing frame 141, and the No. 1 rubber ring can improve the sealing between the U-shaped plate 143 and the processing frame 141. A No. 2 rubber ring is arranged between the U-shaped plate 143 and the sealing frame 144, and the No. 2 rubber ring can improve the sealing between the U-shaped plate 143 and the sealing frame 144.

[0029] The supporting assembly includes a linkage tube 151, a linkage plate 152, a linkage rod 153, a support plate 154, a support rod 155 and a support spring 156.

The intermittent support of the support rod 155 can ensure that the acquisition frame 4 remains stable, avoids tilting or shaking of the acquisition frame 4 due to external environmental factors, and thereby ensures the accuracy and consistency of the waste collection and acquisition process.

[0030] 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.

[0031] 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.

[0032] The U-shaped plate 143 moves upward and contacts the linkage rod 153 and squeezes the linkage rod 153. The linkage rod 153 moves upward due to the squeezing of the U-shaped plate 143. The linkage rod 153 moves upward to drive the linkage plate 152 to move upward. The linkage plate 152 moves upward to squeeze the liquid inside the linkage tube 151. The liquid inside the linkage tube 151 is squeezed by the linkage plate 152 to squeeze the support plate 154. The support plate 154 is squeezed by the liquid inside the linkage tube 151 and moves in a direction close to the insulator body 2. The support plate 154 moves in a direction close to the insulator body 2 to pull the support spring 156. The support spring 156 is pulled by the support plate 154 to produce deformation and accumulate force. At the same time, the support plate 154 moves toward the insulator body 2 and drives the support rod 155 to move and contact with the insulator body 2. After the U-shaped plate 143 moves downward and breaks away from the contact with the linkage rod 153, the support plate 154 moves away from the insulator body 2 under the elastic force of the support spring 156. The support plate 154 moves away from the insulator body 2 and drives the support rod 155 to move. The support rod 155 moves and breaks away from the contact with the insulator body 2. The support rod 155 moves back and forth to intermittently support the acquisition frame 4.
