DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Example 1, reference Figure 1-3 A transformer housing cleaning device includes a transformer housing 27: two cover plates 3 are arranged above the transformer housing 27, a connecting rod 8 and a handle 4 detachably installed between the two cover plates 3 are arranged between the two cover plates 3, and the two cover plates 3 are detachably connected to both ends of the connecting rod 8; a cleaning assembly is arranged between the two cover plates 3, and the cleaning assembly includes a conveyor belt 1, a stepper motor 2, a driving roller 7, a guide roller 6 and a plurality of rollers 13; The driving roller 7, the guide roller 6 and the plurality of rollers 13 are located between the two cover plates 3, the conveyor belt 1 is sleeved on the outside of the driving roller 7 and the plurality of rollers 13, the stepper motor 2 is installed on one of the cover plates 3, and the output shaft of the stepper motor 2 is connected to the driving roller 7, and the bottom of the conveyor belt 1 extends to the bottom of the cover plate 3.

[0030] Reference Fig.10A cleaning wipe 5 is bonded to the outer surface of the conveyor belt 1 , and a plurality of through-type water leakage holes 23 are evenly provided on the cleaning wipe 5 and the conveyor belt 1 .

[0031] When it is necessary to clean the bird droppings on the transformer casing, the equipment is placed on the upper end of the casing. At this time, the conveyor belt 1 together with the cleaning wipe 5 on the lower end face are attached to the surface of the casing, and the power of the stepper motor 2 is turned on. After the power is turned on, the stepper motor 2 drives the driving roller 7 to rotate, and then transfers the kinetic energy to the conveyor belt 1. With the help of the friction generated between the two, the conveyor belt 1 is driven to rotate. At the same time, multiple rollers 13 can support the conveyor belt 1 and rotate with the movement of the conveyor belt 1. When the conveyor belt 1 rotates, the cleaning wipe 5 can wipe off the wet bird droppings when it comes into contact with the wet bird droppings. Compared with the traditional scraper to scrape off the bird droppings, wiping with the cleaning wipe 5 can avoid the problem of scratches on the paint surface of the casing.

[0032] Example 2, reference Figure 4-7 The difference between this embodiment and embodiment 1 is that the two cover plates 3 are also provided with a feeding structure, the feeding structure includes a mixing component and a feeding component, and the feeding component includes a box body 24, a round rod 14, a sphere 15, a material injection port 16, a square groove 17, a contact sensor 25, a first chamber 9, a second chamber 10, a slope 22 and a material leakage structure 12.

[0033] Two first chambers 9 and second chambers 10 of the same size are arranged on the inner side of the box body 24, a square groove 17 is opened in the middle of the upper end of the box body 24, a leakage structure 12 is arranged between the square groove 17 and the lower end of the box body 24, a round rod 14 is connected to the lower end of the leakage structure 12, a sphere 15 is installed at the bottom of the round rod 14, a contact sensor 25 is installed at the bottom of the sphere 15, a material injection port 16 is respectively installed on the upper part of the first chamber 9 and the second chamber 10, and a slope 22 is arranged on the inner side of the first chamber 9.

[0034] The leakage structure 12 includes a partition 121, a block 122 and a slot 123. The upper end of the partition 121 extends to the outside of the square slot 17. The slot 123 is opened at the bottom of the box body 24. The block 122 is clamped on the inner side of the slot 123. The block 122 is arranged in an isosceles trapezoid with a larger upper end size, and the partition 121 is installed on the upper part of the block 122. An electric telescopic rod 26 is connected between the two cover plates 3, and the electric telescopic rod 26 is interconnected with the upper part of the partition 121. The partition 121 divides the first chamber 9 and the second chamber 10 into two independent spaces. The first chamber 9 contains quicklime powder, and the second chamber 10 contains water.

[0035] Bird droppings are soft when they are first produced, but after a period of air drying, the texture of the bird droppings will become extremely hard. At this time, the bird droppings cannot be cleaned away by wiping with a cleaning wipe. At the same time, bird droppings contain uric acid, phosphoric acid, and oxalic acid, which are corrosive substances. Unlike wet bird droppings, dry and hard bird droppings will leave these corrosive substances on the surface of the shell.

[0036] To this end, the bottom of the conveyor belt 1 fits with the surface of the shell and is in a horizontal state. When the conveyor belt 1 contacts the dry and hard bird droppings, the raised guano lumps will push up the contact part of the conveyor belt 1. As the equipment moves, the conveyor belt 1 contacts the contact sensor 25 at the lower end of the upper sphere 15. After the contact sensor 25 is triggered, it transmits a signal to the external control system. After receiving the signal, the control system will start the electric telescopic rod 26 to shrink. In this way, the position of the partition 121 rises, and then the block 122 connected to its lower end will rise upward. Since the bottom size of the block 122 is smaller than the size of its upper part, a gap appears between the block 122 and the slot 123, so that the quicklime powder in the first chamber 9 slides down the slope 22 and leaks out of the slot 123, and the water inside the second chamber 10 leaks out along the other side of the slot 123. In this way, after quicklime and water contact and mix with each other, they fall on the conveyor belt 1 and contact with the surface of the transformer shell along the leakage hole 23 on the conveyor belt 1. Quicklime powder is calcium oxide. Calcium oxide reacts with water to produce calcium hydroxide. This reaction is an exothermic reaction, which can increase the temperature of the falling liquid. Warm water helps to soften the organic matter in the bird droppings. Bird droppings contain chemical components such as urate, ammonia, and phosphoric acid. These components will form hard residues after drying and are difficult to remove. When warm water acts on the dry and hard bird droppings, moisture can penetrate into the structure of the bird droppings, reduce its hardness, and make it easier to wipe or rinse off. Secondly, the calcium hydroxide generated in the reaction is an alkaline substance. When it contacts the acidic substances in the bird droppings, it can neutralize these corrosive acidic substances, thereby effectively removing the corrosive substances attached to the surface of the shell in the process of removing the bird droppings.

[0037] It should be noted that since the wet bird droppings can be removed directly, there is no need to add water and quicklime. The wet bird droppings cannot lift the conveyor belt 1 upward, so the reactants will not be mixed, avoiding the alkaline substance from contacting the surface of the transformer casing without contacting the acidic substance.

[0038] Example 3, reference Figure 5-7The difference between this embodiment and Embodiment 1 and Embodiment 2 is that the mixing component 11 includes a first material receiving plate 111, a second material receiving plate 112, a slot 113, a notch 114 and a conveying pipe 115, the conveying pipe 115 is installed at the bottom of the box body 24, and the position of the slot 123 coincides with the position of the conveying pipe 115, and the two parallel side walls in the conveying pipe 115 are respectively arranged in an array with a plurality of first material receiving plates 111 and second material receiving plates 112, and the first material receiving plates 111 and the second material receiving plates 112 are staggered in the vertical direction, the notch 114 is arranged in the middle of the first material receiving plate 111 and the second material receiving plate 112, and the round rod 14 passes through the notch 114 and extends to the outer side and lower part of the conveying pipe 115.

[0039] The slots 113 are distributed in an array on the upper end surfaces of the first receiving plate 111 and the second receiving plate 112 .

[0040] When water comes into contact with quicklime, sufficient contact is required to increase the degree of reaction.

[0041] To this end, a first receiving plate 111 and a second receiving plate 112 are cross-arranged on both sides of the inner wall of the conveying pipe 15. The water and quicklime powder coming out from both sides of the slot 123 will flow through the first receiving plate 111 and the second receiving plate 112 in sequence, increasing the flow distance and ensuring sufficient contact of the reactants. At the same time, the two cover plates 3 and the handle 4 can be disassembled, so that the reactants can be injected into the first chamber 9 and the second chamber 10 in the box body 24 through the injection port 16 by opening the cover plate 3 on one side.

[0042] Example 4, reference Figure 8-9 The difference between this embodiment and embodiment 1, embodiment 2 and embodiment 3 is that a water collecting box 18 is detachably provided between the two cover plates 3 at the lower end of the conveyor belt 1, and water is contained in the water collecting box 18. A rotating shaft 21 is rotatably provided in the middle of the water collecting box 18, and a plurality of scraping assemblies 20 are distributed in a circular array on the outer side of the rotating shaft 21, and the scraping assemblies 20 are in contact with the conveyor belt 1, and the scraping assemblies 20 include a support plate 2001, scraping teeth 2002 and a through hole 2003.

[0043] The support plates 2001 are distributed in an annular array on the outside of the rotating shaft 21 , the scraping teeth 2002 are evenly arranged on the upper end of the support plates 2001 , and the scraping teeth 2002 are in contact with the outer surface of the conveyor belt 1 , and the through holes 2003 are penetrated through the support plates 2001 .

[0044] Tooth grooves 19 are symmetrically arranged on the two side walls of the water collecting box 18. When the scraper teeth 2002 rotate, they contact with the tooth grooves 19. When the support plate 2001 rotates, there is a gap between the scraper teeth 2002 at the far end and the inner wall of the water collecting box 18, and a water pipe is installed at the bottom of the water collecting box 18, and a valve is set on the water pipe.

[0045] The composition of bird droppings includes indigestible food and fiber. When the amount of bird droppings is large, after wiping off the bird droppings, the fiber will adhere to the surface of the cleaning wipe 5, which makes the fiber re-attached to the surface of the shell when the surface of the transformer shell is repeatedly cleaned.

[0046] To this end, a water collecting box 18 is provided on one side of the cover plate 3, and water is filled in the water collecting box 18. When the conveyor belt 1 passes through the upper end of the water collecting box 18, the cleaning wipe 5 will contact with the scraping teeth 2002 on the upper end of the support plate 2001, and the rotating shaft 21 will be driven to rotate during the contact process. At this time, the scraping teeth 2002 will scrape off the fibers adhering to the surface of the cleaning wipe 5. At this time, the scraping teeth 2002 and the scraped fibers enter below the liquid level inside the water collecting box 18 together, and transfer the fibers to the water. When the amount of fiber is large, the scraped fibers can pass through the through hole 2003 on the support plate 2001 into the space between the two support plates 2001 and into the water. When the adhered substance contains hard lumps, the hard lumps will be stuck between the scraping teeth 2002. In order to solve this problem, a tooth groove 19 is set on the movement trajectory of the scraping teeth 2002, that is, on the inner wall of the water collecting box 18. Through the cooperation of the tooth groove 19 and the scraping teeth 2002, the hard lumps stuck between the scraping teeth 2002 can be scraped off.

[0047] The working principle of the device is: When it is necessary to clean the bird droppings on the transformer casing, the equipment is placed on the upper end of the casing. At this time, the conveyor belt 1 together with the cleaning wipe 5 on the lower end face are attached to the surface of the casing, and the power of the stepper motor 2 is turned on. After the power is turned on, the stepper motor 2 drives the driving roller 7 to rotate, and then transfers the kinetic energy to the conveyor belt 1. With the help of the friction generated between the two, the conveyor belt 1 is driven to rotate. At the same time, multiple rollers 13 can support the conveyor belt 1. With the help of multiple rollers 13 and two cover plates 3, the position of the conveyor belt 1 is ensured not to be offset, and it rotates with the movement of the conveyor belt 1. When the conveyor belt 1 rotates, the cleaning wipe 5 can wipe off the wet bird droppings when it comes into contact with the wet bird droppings. Compared with the traditional scraper to scrape off the bird droppings, wiping with the cleaning wipe 5 can avoid the problem of scratches on the paint surface of the casing.

[0048] Bird droppings are soft when they are first produced, but after a period of air drying, the texture of the bird droppings will become extremely hard and appear as raised blocks. At this time, the bird droppings cannot be cleaned off by wiping with a cleaning wipe 5. At the same time, bird droppings contain uric acid, phosphoric acid, and oxalic acid, which are corrosive substances. Unlike wet bird droppings that can be easily wiped off, dry and hard bird droppings will leave these corrosive substances on the surface of the shell.

[0049] To this end, the bottom of the conveyor belt 1 fits with the surface of the shell and is in a horizontal state. When the conveyor belt 1 contacts the dry and hard bird droppings, the raised bird droppings will push up the contact part of the conveyor belt 1. As the equipment moves, the conveyor belt 1 contacts the contact sensor 25 at the lower end of the upper sphere 15. After the contact sensor 25 is triggered, it transmits a signal to the external control system. After receiving the signal, the control system will start the electric telescopic rod 26 to retract. The working principle of the mutual cooperation between the contact sensor 25 and the electric telescopic rod 26 is a commonly used method in the prior art, which will not be elaborated here. In this way, the position of the partition 121 rises, and then the block 122 connected to its lower end will be lifted upward. Since the bottom size of the block 122 is smaller than the size of its upper part, a gap will appear between the block 122 and the slot 123, so that the quicklime powder in the first chamber 9 slides down the slope 22 and leaks out of the slot 123. The water inside the second chamber 10 leaks out along the other side of the slot 123, so that the quicklime and water contact and mix with each other, and then fall on the conveyor belt 1, and contact with the shell surface of the transformer along the water leakage hole 23 on the conveyor belt 1. The quicklime powder is calcium oxide, and calcium oxide reacts with water to produce calcium hydroxide. The reaction is an exothermic reaction, which can increase the temperature of the falling liquid. Warm water helps to soften the organic matter in the bird droppings. The bird droppings contain chemical components such as urate, ammonia, and phosphoric acid. These components will form hard residues after drying and are difficult to remove. When warm water acts on the dry and hard bird droppings, the moisture can penetrate into the structure of the bird droppings, reduce its hardness, and make it easier to be wiped or rinsed off. Secondly, the calcium hydroxide generated in the reaction is an alkaline substance. When it contacts the acidic substances in the bird droppings, it can neutralize these corrosive acidic substances, thereby effectively removing the corrosive substances attached to the shell surface in the process of removing the bird droppings.

[0050] It should be noted that since the wet bird droppings can be removed directly, there is no need to add water and quicklime. The wet bird droppings cannot lift the conveyor belt 1 upward, so the reactants will not be mixed, avoiding the alkaline substance from contacting the surface of the transformer casing without contacting the acidic substance.

[0051] When water comes into contact with quicklime, sufficient contact is required to increase the degree of reaction.

[0052] To this end, a first receiving plate 111 and a second receiving plate 112 are cross-arranged on both sides of the inner wall of the conveying pipe 15. The water and quicklime powder coming out from both sides of the slot 123 will flow through the first receiving plate 111 and the second receiving plate 112 in sequence, increasing the flow distance and ensuring sufficient contact of the reactants.

[0053] At the same time, both cover plates 3 and handle 4 can be disassembled, so that the reactants can be injected into the first chamber 9 and the second chamber 10 in the box body 24 through the injection port 16 by opening the cover plate 3 on one side.

[0054] The composition of bird droppings includes indigestible food and fiber. When the amount of bird droppings is large, after wiping off the bird droppings, the fiber will adhere to the surface of the cleaning wipe 5, which makes the fiber re-attached to the surface of the shell when the surface of the transformer shell is repeatedly cleaned.

[0055] To this end, a water collecting tank 18 is provided on one side of the cover plate 3, and water is filled in the water collecting tank 18. When the conveyor belt 1 passes through the upper end of the water collecting tank 18, the cleaning wipe 5 will contact with the scraping teeth 2002 on the upper end of the support plate 2001, and the rotating shaft 21 will be driven to rotate during the contact process. At this time, the scraping teeth 2002 will scrape off the fibers adhering to the surface of the cleaning wipe 5. At this time, the scraping teeth 2002 and the scraped fibers enter below the liquid level inside the water collecting tank 18 together, and transfer the fibers into the water. When the amount of fibers is large, the scraped fibers can pass through the through holes 2003 on the support plate 2001, enter between the two support plates 2001 and enter the water.

[0056] When the adhered material contains hard lumps, the hard lumps will be stuck between the scraper teeth 2002. In order to solve this problem, tooth grooves 19 are set on the movement trajectory of the scraper teeth 2002, that is, on the inner wall of the water collecting box 18. The hard lumps stuck between the scraper teeth 2002 are scraped off through the cooperation between the tooth grooves 19 and the rotating scraper teeth 2002.

[0057] The above description is only a preferred specific implementation manner 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 scheme and inventive concept 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.
