Description

Technical Field

[0001] The present invention belongs to the technical field of box-type substations, and in particular relates to an intelligent solar photovoltaic box-type substation. Background Art

[0002] Box-type substation, also known as prefabricated substation or prefabricated substation, is a factory-prefabricated indoor and outdoor compact distribution equipment that integrates high-voltage switchgear, distribution transformers and low-voltage distribution devices according to a certain wiring scheme. It organically combines the functions of transformer step-down and low-voltage distribution and is installed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, anti-theft, heat-insulating, fully enclosed and movable steel structure.

[0003] With reference to the comparative document, the publication number is CN117458301A. The present invention relates to the technical field of photovoltaic box-type substations, and specifically to an intelligent solar photovoltaic box-type substation, comprising a box body, wherein the side panels on both sides of the box body are symmetrically provided with air inlet channels, and the air inlet side of the air inlet channels is provided with blades, characterized in that the blades include left blades and right blades. The present invention arranges left blades and right blades in the air inlet channels on both sides of the box body. When the wind blows outside, the larger wind force will push the left blades and the right blades to deflect to the first position through the driving part and the pushing part, so that the air inlet channel is formed with a large inlet and a small outlet under the composition of the left fan blade and the right fan blade, and can compress the inflowing air and increase the flow rate of the air at the outlet of the air inlet channel. The faster airflow can increase the rate of convective heat transfer, so that the heat of the electrical components inside the box body can be transferred to the air faster, which can effectively improve the heat dissipation efficiency of the electrical components.

[0004] Although the comparative documents use multiple fans to ventilate the box, the existing box-type smart photovoltaic box-type substations are usually installed outdoors and exposed to the natural environment for a long time. Dust, oil, debris, etc. are easily accumulated on its surface, especially the heat sink and other parts. The existing smart photovoltaic box-type substations usually lack cleaning mechanisms. If a large amount of dirt accumulates on the surface of the heat sink and is not cleaned, an insulation layer will be formed, which will hinder heat dissipation, further aggravate the heat dissipation problem of the equipment, and affect the use effect of the entire substation. At the same time, existing substations usually have filter ventilation panels for internal ventilation, but as the ventilation time increases, impurities left by the filtered air will adhere to the surface of the filter ventilation panel, such as dust, mosquito corpses, leaves, etc. The existing smart photovoltaic box-type substations usually lack cleaning mechanisms for the filter ventilation panels. If the surface of the filter ventilation panel is not cleaned, the surface of the filter ventilation panel will be blocked over time, affecting the ventilation effect of the filter ventilation panel, thereby increasing the temperature and humidity in the box, accelerating equipment aging, and reducing equipment performance and reliability. Summary of the Invention

[0005] The purpose of the present invention is to provide an intelligent solar photovoltaic box-type substation to solve the problems raised in the above background technology.

[0009] Through the setting of the above scheme, the heat exchanger cleaning mechanism uses the up and down movement of the cleaning box to allow the soft brush to scrape and clean the dust on the surface of the heat sink in all directions.

[0014] Through the setting of the above scheme, after switching to the hard brush to clean the heat exchanger, the interaction between the magnetic plate and the magnetic plate is triggered, so that the spray gun sprays the detergent through the atomizing nozzle, which greatly improves the cleaning effect and effectively avoids the formation of an insulation layer on the heat sink due to the accumulation of impurities, thereby ensuring good heat dissipation performance of the box and extending the service life of the equipment.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. Through the setting of the heat exchanger cleaning mechanism, when there is ordinary dust on the surface of the heat sink, the cleaning box will use a soft brush to scrape and clean the dust on the surface of the heat sink under the drive of the adjustment rod. If there are impurities on the surface of the heat sink that are difficult to clean, such as oil, the rotating rod will flip at this time, and the oil on the surface of the heat sink will be cleaned by a harder hard brush. While the hard brush is cleaning the oil, the spray gun will spray detergent on the surface of the heat sink through the atomizing nozzle to improve the cleaning effect of the hard brush on the oil. By cleaning the surface of the heat sink, it can effectively avoid the attachment of more impurities on the heat sink, which affects the heat dissipation of the box.

[0020] 2. The setting of the ventilation plate cleaning mechanism: when the cleaning box moves back and forth to clean the surface of the heat sink, the scraper will be pushed by the pressure rod to scrape the surface of the filter ventilation plate to clean the impurities filtered out from the surface of the filter ventilation plate, so as to avoid a lot of impurities adhering to the surface of the filter ventilation plate, which will affect the subsequent ventilation effect of the box.

DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0030] Example 1

[0031] like Figure 1-4As shown, an intelligent solar photovoltaic box-type substation includes a box body 1, a flip door 101 is provided on the box body 1, a plurality of handles 102 are provided on the flip door 101, a plurality of heat sinks 107 are provided on the side of the box body 1 away from the flip door 101, and a heat exchanger cleaning mechanism is provided on the box body 1;

[0032] The heat exchanger cleaning mechanism includes two slide rails 103 arranged on the outer wall of the box body 1, and the interior of the two slide rails 103 is rotatably connected with an adjusting rod 105, and the adjusting rod 105 consists of a smooth section located at the bottom and a reciprocating thread 108 located at the top. The outer wall of the slide rail 103 is fixedly connected to a drive motor 104, and one end of the two adjusting rods 105 is connected to the output end of the drive motor 104. A belt 106 is sleeved between the ends of the two adjusting rods 105, and a cleaning box 3 is commonly threaded on the two reciprocating threads 108. A starting motor 302 is fixedly connected to the outer wall of the cleaning box 3, and a transmission rod 305 is provided at the output end of the starting motor 302. The end of the transmission rod 305 away from the starting motor 302 is fixedly connected to a turntable 307, and the outer wall of the turntable 307 is fixedly connected to the outer wall of the turntable 307. The rotatable connection is with a swing arm 306, and slide grooves 310 are provided on both sides of the cleaning box 3. The inside of the two slide grooves 310 are slidably connected to the driving box 309. The end of the swing arm 306 away from the turntable 307 is rotatably connected to the driving box 309, and the inside of the driving box 309 is rotatably connected to the rotating rod 319. Electric flip shafts 311 are provided on both sides of the rotating rod 319. Multiple dust cleaning plates 320 are fixedly connected to the outer wall of the rotating rod 319, and multiple soft brushes 321 are fixedly connected to the outer walls of the multiple dust cleaning plates 320. Multiple oil cleaning plates 322 are fixedly connected to the side of the rotating rod 319 away from the dust cleaning plate 320, and multiple hard brushes 323 are fixedly connected to the outer walls of the multiple oil cleaning plates 322. A trigger magnetic plate 324 is fixedly connected to the outer wall of the rotating rod 319.

[0033] The present invention is further described in detail. A dust suction port 308 is provided on the cleaning box 3 , and a dust collector 301 is provided on the dust suction port 308 .

[0034] As can be seen from the above, during use, if it is found that there is a lot of dust remaining on the surface of the heat sink 107 on the box body 1 and needs to be cleaned, the operator can turn on the drive motor 104, and the drive motor 104 drives the adjusting rod 105 connected to its output end to rotate. Through the action of the belt 106, when one adjusting rod 105 rotates, it will drive the other adjusting rod 105 to rotate synchronously. When the two adjusting rods 105 rotate synchronously, under the action of the reciprocating thread 108, the cleaning box 3 will reciprocate up and down. When the cleaning box 3 reciprocates up and down, the operator can turn on the starting motor 302, so that it drives the turntable 307 to rotate through the transmission rod 305. When the turntable 307 rotates, the swing arm 306 is used to move the rotary table 307. When the cleaning box 3 is used, the driving box 309 is driven to move up and down along the slide 310. When the driving box 309 is driven to move up and down, the soft brush 321 is used to scrape and clean the dust on the surface of the heat sink 107. After the soft brush 321 and the cleaning box 3 have scraped and cleaned the surface of the heat sink 107, the operator can turn on the vacuum cleaner 301. When the vacuum cleaner 301 is turned on, negative pressure is generated inside the suction port 308, thereby collecting the cleaned dust. The transmission system consisting of the drive motor 104, the adjustment rod 105, the belt 106 and the reciprocating thread 108 can realize the stable up and down reciprocating motion of the cleaning box 3, so that the soft brush 321 can comprehensively and efficiently scrape and clean the dust on the surface of the heat sink 107. The entire cleaning process has a high degree of automation, reduces manual operation, reduces labor intensity, improves cleaning efficiency, can quickly remove a large amount of dust, and ensures that the heat sink 107 can restore its heat dissipation performance in a timely manner.

[0035] Example 2

[0036] like Figure 4-7 As shown, both sides of the outer wall of the cleaning box 3 are fixedly connected with a liquid storage box 303, a liquid filling port 304 is opened on the liquid storage box 303, and a spraying mechanism is provided on the liquid storage box 303.

[0037] The spraying mechanism includes a plurality of mounting plates 312 arranged on the liquid storage tank 303, and a spray barrel 313 is fixedly connected to the outer wall of each mounting plate 312. A push rod 318 is slidably connected to the inside of the spray barrel 313, and a pressure spring 317 is sleeved on the push rod 318.

[0038] The end of the spray barrel 313 away from the push rod 318 is connected to an atomizing nozzle 315, and the interior of the spray barrel 313 is connected to a suction pipe 314. The end of the suction pipe 314 away from the spray barrel 313 is connected to the interior of the liquid storage tank 303. A one-way valve is provided inside the atomizing nozzle 315 and the suction pipe 314. The bottoms of multiple push rods 318 are commonly connected to a magnetic plate 316, and the magnetic poles of the magnetic plate 316 are the same as the magnetic poles of the trigger magnetic plate 324.

[0039] The box body 1 is provided with a filter ventilation plate 2 , the side wall of the filter ventilation plate 2 is fixedly connected with a side rail 204 , and a ventilation plate cleaning mechanism is provided inside the side rail 204 .

[0040] The ventilation plate cleaning mechanism includes a scraper 201 that is slidably arranged inside the side rail 204. The scraper 201 is in sliding contact with the surface of the filter ventilation plate 2. A return spring 203 is fixedly connected to the outer wall of one end of the scraper 201 located inside the side rail 204. The end of the return spring 203 away from the scraper 201 is fixedly connected to the inner wall of the side rail 204.

[0041] As can be seen from the above, during use, if it is found that there is oil residue on the surface of the heat sink 107 that is difficult to clean, before cleaning the heat sink 107, the operator can allow the electric flip shaft 311 to drive the rotating rod 319 to flip 180 degrees. When the rotating rod 319 is flipped, the oil cleaning plate 322 can replace the dust cleaning plate 320 to extend out of the driving box 309. When the oil cleaning plate 322 is flipped to replace the dust cleaning plate 320 and extend out of the driving box 309, it will also drive the trigger magnetic plate 324 upward. When the trigger magnetic plate 324 is flipped upward, the operator can turn on the drive motor 104 at this time. When the drive motor 104 drives the adjusting rod 105 to rotate, repeat the above steps, and the cleaning box 322 will be cleaned. The cleaning box 3 performs reciprocating motion up and down. When the cleaning box 3 performs reciprocating motion up and down, the operator can turn on the starting motor 302 again to drive the turntable 307 to rotate through the transmission rod 305. Referring to the above principle, when the turntable 307 rotates, it will cause the driving box 309 to reciprocate along the slide groove 310 and scrape the surface of the heat sink 107 through the hard brush 323. Since the hard brush 323 has a higher hardness than the soft brush 321, it will have greater friction when in contact with the heat sink 107, making it easier to clean stubborn stains. When the driving box 309 reciprocates, it will drive the flip-up trigger magnetic plate 324 to move synchronously. Due to the contact between the magnetic plate 316 and the trigger magnetic plate 324, the hard brush 323 will be scraped and cleaned. The magnetic poles are the same, so when the flipped upward trigger magnetic plate 324 moves upward with the driving box 309 and approaches the magnetic plate 316, the push rod 318 will be pushed into the nozzle 313 under the action of the repulsive magnetic force. When the trigger magnetic plate 324 moves downward with the driving box 309 and away from the magnetic plate 316, the distance between the two becomes farther. At this time, under the elastic force of the pressing spring 317, the push rod 318 will move down and back to its original position. Therefore, when the trigger magnetic plate 324 reciprocates with the driving box 309, the push rod 318 will perform a piston motion in the nozzle 313 under the combined action of the intermittent magnetic force and the elastic force of the pressing spring 317. When the push rod 318 performs a piston motion in the nozzle 313 When cleaning, the cleaning liquid stored in the liquid storage tank 303 will be sucked into the spray barrel 313 through the liquid suction pipe 314, and then sprayed onto the heat sink 107 through the atomizing nozzle 315. The stubborn stains on the surface of the heat sink 107 are cleaned by scraping with the hard brush 323. When the surface of the heat sink 107 is cleaned, the cleaning liquid can be reused after it is naturally dried. The oil stains on the heat sink 107 can be thoroughly cleaned to effectively prevent the oil stains from forming an insulating layer to hinder heat dissipation, ensure that the heat sink 107 continues to dissipate heat efficiently, maintain the internal equipment of the box body 1 at a suitable working temperature, reduce the risk of equipment failure due to poor heat dissipation, extend the service life of the equipment, and ensure the stable and reliable operation of the box-type substation.

[0042] When the cleaning box 3 moves down to clean the surface of the heat sink 107, it will contact and push the pressure rod 202 downward, and the pressure rod 202 will push the scraper 201 downward along the side rail 204. When the cleaning box 3 moves down to the maximum stroke and moves upward, the scraper 201 will also move upward under the elastic force of the return spring 203. Therefore, when the cleaning box 3 moves up and down to clean the surface of the heat sink 107, under the push of the pressure rod 202 and the elastic force of the return spring 203, the scraper 201 will scrape back and forth on the surface of the filter ventilation plate 2, cleaning the impurities filtered down on the surface of the filter ventilation plate 2, and timely cleaning the impurities filtered down on the surface of the filter ventilation plate 2, such as dust, mosquito corpses, leaves, etc., avoiding the blockage problem caused by the accumulation of impurities on the surface of the filter ventilation plate 2, ensuring the ventilation effect of the filter ventilation plate 2, and good ventilation can make the air inside the box 1 circulate smoothly, effectively reducing the temperature and humidity in the box 1, and reducing the aging and failure risks of the box 1 due to environmental factors.

[0043] It should be noted that one-way valves are provided inside the liquid suction pipe 314 and the atomizing nozzle 315 to ensure that the liquid suction pipe 314 only sucks liquid and the atomizing nozzle 315 only sprays liquid.

[0044] It should be noted that when the soft brush 321 cleans the dust on the surface of the heat sink 107, the trigger magnetic plate 324 is flipped downward. When the flipped downward trigger magnetic plate 324 reciprocates with the driving box 309, the magnetic force generated between the two is weak due to the long distance from the magnetic plate 316, and will not push the push rod 318 to move. Accordingly, when cleaning ordinary dust, the atomizing nozzle 315 will not spray cleaning liquid.

[0045] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
