[0011] Preferably, the air injection assembly further comprises a sliding plate fixedly connected to the bottom of the spring plate, the inner wall of the air pressure frame is fixedly connected with an extension block, and the inner wall of the extension block is slidably connected with the outer wall of the sliding plate. Wherein, the air flow sucked by the fan will enter the two flow dividing blocks, and the dust is divided into two flows, when the two flows flow out of the flow dividing blocks, the two flows will collide with each other, slow down the flow speed of the dust in the air flow, reduce the impact force of the dust, effectively prevent the dust in the outside from flowing into the filter cylinder at a high speed and impacting the filter cylinder frequently, which can damage the filter cylinder and affect the filtering effect of the dust.

[0012] Preferably, the acceleration assembly comprises a connecting rod slidingly connected to the inner wall of the dustproof frame, the top of the spring plate is fixedly connected to the bottom of the connecting rod, and the side, away from the spring plate, of the connecting rod is rotationally connected with a connecting rod two; The side wall of the piston plate is rotationally connected to the inner wall of the connecting rod two, the inner wall of the flow guide plate is provided with an air hole, and the inner wall of the dustproof frame is slidingly connected with a spring air blocking plate; When the spring plate descends, the connecting rod will descend, push the connecting rod two to rotate, and make the connecting rod two push the piston plate to move, when the piston plate covers the air hole, the gas on the left side of the piston plate will be squeezed, and the squeezed gas will be blocked by the spring air blocking plate, so the gas pressure will increase, with the continuous movement of the piston plate, the piston plate will push the spring air blocking plate away from the flow guide plate, at this time, the high-pressure gas will be sprayed out, the flow speed of the air flow in the dustproof frame will be accelerated, the pushing force of the air flow out of the exhaust block will be ensured, and the air flow speed is slowed down after the air flow collides with the two flow dividing blocks, the resistance of the air flow to the outside dust is weakened, and the outside dust may enter the protective shell from the exhaust block.

[0013] Preferably, the inclination assembly comprises a rotating plate rotationally connected to the inner wall of the dustproof frame, the bottom of the piston plate is fixedly connected with five arc springs, and the side, away from the rotating plate, of the five arc springs is fixedly connected to the side wall of the dustproof frame; The outer wall of the connecting rod is fixedly connected with a pushing plate, and the bottom of the rotating plate is fixedly connected with an L-shaped plate; When the connecting rod descends, the pushing plate will descend, with the continuous movement of the pushing plate, the pushing plate will contact the L-shaped plate, push the L-shaped plate to move, make the rotating plate rotate, make the arc springs be stretched, so that the arc springs generate a rebound force, when the rotating plate rotates, the rotating plate will be inclined, and a gap between the rotating plate and the dustproof frame is leaked, so that the dust on the top of the rotating plate flows out along the surface of the rotating plate, effectively preventing that part of the heavy dust after the collision of the two flows of dust may settle on the top of the rotating plate and cause accumulation, when the outside is in strong wind weather, the flow speed of the air flow sucked by the fan from the outside may be accelerated, the accumulated dust may be re-raised and attached to the surface of the filter cylinder.

[0014] The present application has the following beneficial effects: (1) When using this invention, the dust blocking component blocks external sand and dust. Then, the fan is started to draw in external airflow into the dustproof frame. At the same time, the motor is started to drive the filter cartridge to rotate and filter the sand and dust. When the filter cartridge rotates, it will drive the concave and convex rings to rotate, squeeze the jet component, and cause the spring plate to drop, squeezing the gas in the air pressure frame and increasing the gas pressure until the high-pressure gas will be sprayed out onto the filter cartridge, so that the sand and dust attached to the filter cartridge are separated from the filter cartridge. In the process of filtering sand and dust, the filter cartridge is cleaned at the same time to keep the filter cartridge unobstructed and continuously filter sand and dust. This effectively prevents the filter cartridge from being easily blocked due to the large amount of sand and dust in the Northwest region, thus continuously blocking sand and dust.

[0015] (2) In this invention, the airflow drawn in by the fan will enter two diversion blocks, which will split the airflow into two streams. When the two streams of airflow flow out from the diversion blocks, they will collide with each other, reducing the impact force of sand and dust in the airflow. This effectively prevents the sand and dust drawn in by the fan from flowing too fast and having a large impact force, which will frequently impact the filter cartridge and easily cause damage to the filter cartridge. In addition, the arc plate and the inclined block will block the airflow generated by the fan from contacting the top of the filter cartridge, effectively preventing the airflow from moving towards the air pressure frame and generating convection with the high-pressure gas ejected from the air pressure frame, which would affect the cleaning of the filter cartridge by the high-pressure gas in the air pressure frame.

[0016] (3) When the spring plate descends, the connecting rod will descend. Through the acceleration component, the piston plate will be pushed to move, compress the gas, and increase the gas pressure. As the piston plate continues to move, the high-pressure gas will be ejected, which will accelerate the flow speed of the airflow in the dustproof frame and ensure the driving force of the gas discharged from the exhaust block. This effectively prevents the airflow from slowing down after the two diversion blocks collide, which would slow down the flow speed of the airflow discharged from the exhaust block and weaken the blocking force against external sand and dust. External sand and dust may enter the protective shell from the exhaust block.

[0017] (4) When the connecting rod descends, the push plate will descend. Through the tilting component, the rotating plate will tilt and a gap will be made between it and the dustproof frame, allowing the sand and dust on the top of the rotating plate to flow out along the surface of the rotating plate. This effectively prevents the heavier sand and dust from colliding and settling on the top of the rotating plate, causing accumulation. When there is strong wind outside, the airflow speed of the fan may increase, attracting the accumulated sand and dust. The accumulated sand and dust may be raised again and attached to the surface of the filter cartridge, causing the filter cartridge to absorb too much sand and dust in a short time, causing the filter cartridge to be blocked and affecting the airflow.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1, please refer to Figures 1-4 The present invention is an integrated protective dry-type transformer and protective device, including a protective shell 111, and two dustproof frames 113 are fixedly connected to the side wall of the protective shell 111. The two dustproof frames 113 contain the same parts. The protective mechanism 1 has a dust-blocking component 11 fixedly installed on its side wall and a drive mechanism 12 installed on its inner wall. The dust-blocking component 11 is used to block sand and dust. Dust removal mechanism 2, installed on the inner wall of dust blocking assembly 11, is used to block and discharge sand and dust; and Speed-increasing mechanism 3 is located on the inner wall of dust-blocking assembly 11 and is used to accelerate the airflow speed. A filter cartridge 123 is rotatably connected to the inner wall of the dustproof frame 113, a concave-convex ring 211 is fixedly connected to the outer wall of the filter cartridge 123, and an air pressure frame 212 is fixedly connected to the inner wall of the dustproof frame 113. The dust-blocking component 11 prevents sand and dust from entering the protective housing 111. The drive mechanism 12 draws in external airflow for cooling and filters the sand and dust in the airflow. The filtered sand and dust are then discharged by the dust removal mechanism 2. During the process of filtering sand and dust, the filter cartridge 123 is cleaned to keep it unobstructed and continuously filter sand and dust. Finally, the speed-increasing mechanism 3 accelerates the flow of gas.

[0023] Protective mechanism 1 includes: Dust-blocking component 11 is fixedly installed on the side wall of the dust-blocking component 11 and the side wall of the protective housing 111 to block sand and dust; The drive mechanism 12 is fixedly installed on the outer wall of the drive mechanism 12 and the inner wall of the dustproof frame 113, and is used to draw in airflow to cool the inside of the protective shell 111. The dust-blocking component 11 blocks external sand and dust, preventing sand and dust from entering the protective shell 111. The drive mechanism 12 is activated to draw in airflow, which cools the inside of the protective shell 111 and filters the sand and dust in the airflow.

[0024] Dust removal mechanism 2 includes: The jet assembly 21 is slidably disposed on the inner wall of the air pressure frame 212 via a sliding member, and is used to spray gas to clean the filter cartridge 123; The sliding component includes a spring plate 213 that is slidably connected to the inner wall of the pneumatic frame 212, and a Z-shaped rod 214 that is slidably connected to the inner wall of the dustproof frame 113. The flow guiding component 22 is rotatably mounted on the inner wall of the filter cartridge 123 via a rotating component, and is used to reduce the impact force of sand and dust. The rotating component includes an inclined block 221 rotatably connected to the inner wall of the filter cartridge 123, and an arc-shaped plate 222 is fixedly connected to the side wall of the inclined block 221. When the drive mechanism 12 moves, it causes the jet assembly 21 to spray high-pressure gas into the filter cartridge 123, expelling sand and dust from the filter cartridge 123. The flow guide assembly 22 slows down the movement speed of the sand and dust, preventing the sand and dust from impacting the filter cartridge 123. This process of filtering sand and dust simultaneously cleans the filter cartridge 123, keeping it unobstructed. This effectively prevents the filter cartridge 123 from becoming easily clogged due to the large amount of sand and dust in the Northwest region. The flow guide assembly 22 slows down the movement speed of the sand and dust, preventing the sand and dust from impacting the filter cartridge 123 and causing damage, thus extending the service life of the filter cartridge 123.

[0025] The three growth-promoting institutions include: Acceleration component 31 is fixedly installed on the inner wall of dustproof frame 113 by a support member to accelerate the airflow speed. The support includes a guide plate 311 fixedly connected to the inner wall of the dustproof frame 113, and a piston plate 312 slidably connected to the inner wall of the dustproof frame 113. The tilting component 32 is rotatably mounted on the inner wall of the dustproof frame 113 to discharge falling sand and dust. When the jet assembly 21 moves, it causes the acceleration assembly 31 to move, compressing the airflow inside the dustproof frame 113 and increasing the gas pressure. As the piston plate 312 continues to move, the high-pressure gas will be ejected, accelerating the flow speed of the airflow inside the dustproof frame 113. At the same time, it will drive the tilting assembly 32 to rotate, expelling the sand and dust that has settled inside the dustproof frame 113, effectively preventing some of the heavier sand and dust from accumulating after the two streams of sand and dust collide.

[0026] Example 2, please refer to Figures 1-8 The present invention is an integrated protective dry-type transformer and protective device. Based on Example 1, the dustproof component 11 includes a dry-type transformer 112 fixedly connected to the inner wall of the protective shell 111, and an exhaust block 114 fixedly connected to the side of the protective shell 111 away from the dustproof frame 113. The drive mechanism 12 includes a fan 121 fixedly connected to the inner wall of the dustproof frame 113, a motor 122 fixedly connected to the inner wall of the dustproof frame 113, and the output end of the motor 122 fixedly connected to the side wall of the filter cartridge 123. The protective casing 111 prevents external sand and dust from directly contacting the dry-type transformer 112, thus protecting the transformer. Then, the fan 121 is started to draw in external airflow into the dustproof frame 113. At the same time, the motor 122 is started to drive the filter cartridge 123 to rotate. The sand and dust carried in the airflow will come into contact with the filter cartridge 123 and be filtered by the filter cartridge 123. The airflow is then allowed to pass through the dustproof frame 113 and enter the protective casing 111, allowing the air inside the protective casing 111 to circulate and cool the dry-type transformer 112. The airflow that enters the protective casing 111 will be discharged through the exhaust block 114.

[0027] The jet assembly 21 includes a connecting rod 215 rotatably connected to the side wall of the Z-shaped rod 214, the top of the spring plate 213 rotatably connected to the inner wall of the connecting rod 215, and the side of the Z-shaped rod 214 away from the connecting rod 215 slidably connected to the side wall of the concave-convex ring 211.

[0028] The jet assembly 21 also includes a sliding plate 216 fixedly connected to the bottom of the spring plate 213, and an extension block 217 fixedly connected to the inner wall of the air pressure frame 212, with the inner wall of the extension block 217 slidably connected to the outer wall of the sliding plate 216. When the filter cartridge 123 rotates, it drives the concave-convex ring 211 to rotate. As the concave-convex ring 211 continues to rotate, the protruding part of the concave-convex ring 211 will squeeze the Z-shaped rod 214 to move, causing the Z-shaped rod 214 to push the connecting rod 215 to rotate. The connecting rod 215 pushes the spring plate 213 to descend, accumulating rebound force. The spring plate 213 will drive the sliding plate 216 to descend. When the sliding plate 216 enters the extension block 217, the bottom of the spring plate 213 is in a sealed state. The spring plate 213 will then squeeze the gas in the air pressure frame 212. The squeezed gas will be blocked by the sliding plate 216, causing the gas pressure to rise until the sliding plate 216 separates from the extension block 217, removing the obstruction to the gas. The high-pressure gas will then be sprayed out towards the filter cartridge 123, causing the sand and dust attached to the filter cartridge 123 to be separated from the filter cartridge 123. Separation of step 23 allows sand and dust to fall onto inclined block 221 and slide down to the arc surface of arc plate 222, expelling the sand and dust. When the protruding part of the concave-convex ring 211 separates from the Z-shaped rod 214, the rebound force of spring plate 213 is released, causing it to return to its original position. This allows sliding plate 216 to return to its original position and separate from extension block 217, allowing external gas to enter the air pressure frame 212 through extension block 217. This continues until the concave-convex ring 211 presses the Z-shaped rod 214 again, causing spring plate 213 to descend and compress gas to clean filter cartridge 123. This process is repeated, achieving the simultaneous cleaning of filter cartridge 123 while filtering sand and dust, keeping filter cartridge 123 unobstructed, and enabling continuous filtration of sand and dust. This effectively prevents the filter cartridge 123 from becoming clogged due to the large amount of sand and dust in Northwest China, and sustainably blocks sand and dust.

[0029] The flow guiding component 22 includes two diversion blocks 224 fixedly connected to the inner wall of the dustproof frame 113, the top of the arc plate 222 is fixedly connected to the inner wall of the dustproof frame 113, and two dust discharge pipes 223 are connected through the inner wall of the arc plate 222. The airflow drawn in by the fan 121 enters two diversion blocks 224, splitting the sand and dust into two streams. When the two streams of air flow out of the diversion blocks 224, they collide with each other, slowing down the flow speed of the sand and dust in the airflow and reducing the impact force of the sand and dust. This effectively prevents the sand and dust drawn in by the fan 121 from flowing too fast and having a large impact force, which would frequently impact the filter cartridge 123 and easily damage the filter cartridge 123, affecting the filtration effect of the sand and dust.

[0030] The acceleration component 31 includes a connecting rod 313 that is slidably connected to the inner wall of the dustproof frame 113, the top of the spring plate 213 is fixedly connected to the bottom of the connecting rod 313, and a connecting rod 314 is rotatably connected to the side of the connecting rod 313 away from the spring plate 213. The side wall of piston plate 312 is rotatably connected to the inner wall of connecting rod 314, the inner wall of guide plate 311 is provided with air hole 315, and the inner wall of dustproof frame 113 is slidably connected with spring air blocking plate 316. When the spring plate 213 descends, it drives the connecting rod 313 to descend, pushing the second connecting rod 314 to rotate. The second connecting rod 314 then pushes the piston plate 312 to move. When the piston plate 312 covers the air hole 315, it squeezes the gas on the left side of the piston plate 312. The squeezed gas is blocked by the spring air-blocking plate 316, so the gas pressure will increase. As the piston plate 312 continues to move, it will push the spring air-blocking plate 316 to separate from the guide plate 311. At this time, the high-pressure gas will be ejected, accelerating the flow speed of the airflow in the dustproof frame 113. This ensures the driving force for the gas to be discharged from the exhaust block 114, effectively preventing the airflow from colliding with the two diverting blocks 224, which would slow down the gas flow rate and reduce the blocking force against external sand and dust. External sand and dust may then enter the protective shell 111 from the exhaust block 114.

[0031] The tilting assembly 32 includes a rotating plate 321 rotatably connected to the inner wall of the dustproof frame 113, and five arc-shaped springs 322 are fixedly connected to the bottom of the piston plate 312. The side of the five arc-shaped springs 322 away from the rotating plate 321 is fixedly connected to the side wall of the dustproof frame 113. A push plate 323 is fixedly connected to the outer wall of the connecting rod 313, and an L-shaped plate 324 is fixedly connected to the bottom of the rotating plate 321. When the connecting rod 313 descends, it will drive the push plate 323 to descend. As the push plate 323 continues to move, it will contact the L-shaped plate 324, pushing the L-shaped plate 324 to move and causing the rotating plate 321 to rotate. This will stretch the arc spring 322, causing it to generate a rebound force. When the rotating plate 321 rotates, it will tilt, and at the same time, a gap will appear between it and the dustproof frame 113, allowing the sand and dust on the top of the rotating plate 321 to flow out along the surface of the rotating plate 321. This effectively prevents the heavier sand and dust from settling on the top of the rotating plate 321 after the two streams of sand and dust collide, causing accumulation. When there is strong wind outside, the airflow speed of the fan 121 may increase, attracting the accumulated sand and dust. The accumulated sand and dust may be stirred up again and adhere to the surface of the filter cartridge 123.

[0032] The number of the above components is not limited. Those skilled in the art can set it freely according to actual needs, as long as the above components are installed at the corresponding component connection positions.

[0033] A specific application of this embodiment is as follows: When using this invention, the protective shell 111 prevents external sand and dust from directly contacting the dry-type transformer 112, thus protecting the dry-type transformer 112. Then, the fan 121 is started to draw in external airflow into the dustproof frame 113. At the same time, the motor 122 is started to drive the filter cartridge 123 to rotate. The sand and dust carried in the airflow will come into contact with the filter cartridge 123 and be filtered by the filter cartridge 123. The airflow is then allowed to pass through the dustproof frame 113 and enter the protective shell 111, allowing the gas inside the protective shell 111 to circulate and protect the dry-type transformer 112. 2. To cool down, the airflow entering the protective shell 111 will be discharged through the exhaust block 114. When the filter cartridge 123 rotates, it will drive the concave-convex ring 211 to rotate. As the concave-convex ring 211 continues to rotate, the protruding part of the concave-convex ring 211 will squeeze the Z-shaped rod 214 to move, causing the Z-shaped rod 214 to push the connecting rod 215 to rotate. This causes the connecting rod 215 to push the spring plate 213 down, accumulating rebound force. The spring plate 213 will drive the sliding plate 216 down. When the sliding plate 216 enters the extension block 217, the bottom of the spring plate 213 is in a sealed state, and the spring... The spring plate 213 will compress the gas inside the air pressure frame 212. The compressed gas is blocked by the sliding plate 216, causing the gas pressure to rise until the sliding plate 216 separates from the extension block 217, removing the obstruction to the gas. The high-pressure gas will then be sprayed out onto the filter cartridge 123, causing the sand and dust attached to the filter cartridge 123 to separate from the filter cartridge 123. The sand and dust will fall onto the inclined block 221 and slide down the inclined block 221 to the arc surface of the arc plate 222, and be discharged through the dust discharge pipe 223. When the protruding part of the concave-convex ring 211 separates from the Z-shaped rod 214, the spring plate 213... The rebound force will be released, causing it to return to its original position, allowing the sliding plate 216 to return to its original position and separate from the extension block 217. This allows external gas to enter the air pressure frame 212 through the extension block 217, until the concave-convex ring 211 squeezes the Z-shaped rod 214 again, causing the spring plate 213 to descend and compress the gas to clean the filter cartridge 123. This process is repeated, so that while the filter cartridge 123 is filtering sand and dust, it is also cleaning the filter cartridge 123, keeping it unobstructed and able to continuously filter sand and dust. This effectively prevents the filter cartridge 123 from clogging easily due to the large amount of sand and dust in the Northwest region, and sustainably blocks sand and dust. Secondly, the airflow drawn in by the fan 121 enters the two diversion blocks 224, splitting the sand and dust into two streams. When the two streams of airflow flow out of the diversion blocks 224, they collide with each other, slowing down the flow speed of the sand and dust in the airflow and reducing the impact force of the sand and dust. This effectively prevents the sand and dust drawn in by the fan 121 from flowing too fast and having a large impact force, which would frequently impact the filter cartridge 123 and easily damage the filter cartridge 123, affecting the filtration effect of the sand and dust. In addition, the arc plate 222 and the inclined block 221 prevent the airflow generated by the fan 121 from contacting the top of the filter cartridge 123, effectively preventing the airflow from moving towards the pressure frame 212 and creating convection with the high-pressure gas ejected from the pressure frame 212, which would affect the cleaning of the filter cartridge 123 by the high-pressure gas in the pressure frame 212. Secondly, when the spring plate 213 descends, it will drive the connecting rod 313 to descend, pushing the connecting rod 314 to rotate, causing the connecting rod 314 to push the piston plate 312 to move. When the piston plate 312 covers the air hole 315, it will squeeze the gas on the left side of the piston plate 312. The squeezed gas is blocked by the spring air blocking plate 316, so the gas pressure will increase. As the piston plate 312 continues to move, the piston plate 312 will push the spring air blocking plate 316 to separate from the guide plate 311. At this time, the high-pressure gas will be ejected, accelerating the flow speed of the airflow in the dustproof frame 113, ensuring the driving force of the gas discharged from the exhaust block 114, effectively preventing the airflow from colliding with the two diverting blocks 224, which would slow down the gas flow rate and reduce the flow speed of the airflow discharged from the exhaust block 114, weakening the blocking force against external sand and dust. External sand and dust may enter the protective shell 111 from the exhaust block 114. When the spring plate 213 rises due to the release of its elastic force, it will drive the connecting rod 313 back to its original position, pull the piston plate 312 back to its original position, and make the air hole 315 connect with the left side of the piston plate 312 again to replenish the gas. Secondly, when the connecting rod 313 descends, it will drive the push plate 323 to descend. As the push plate 323 continues to move, it will contact the L-shaped plate 324, pushing the L-shaped plate 324 to move, causing the rotating plate 321 to rotate. This stretches the arc spring 322, causing it to generate a rebound force. When the rotating plate 321 rotates, it will tilt, and at the same time, a gap will appear between it and the dustproof frame 113, allowing the sand and dust on the top of the rotating plate 321 to flow out along the surface of the rotating plate 321. This effectively prevents the heavier sand and dust from colliding and settling on the top of the rotating plate 321, causing accumulation. When there is strong wind outside, the airflow speed of the fan 121 may increase, attracting the accumulated sand and dust. The accumulated sand and dust may be stirred up again and adhere to the surface of the filter cartridge 123, causing the filter cartridge 123 to absorb too much sand and dust in a short time, clogging the filter cartridge 123 and affecting the airflow.
