Description
Technical Field
[0001] The present invention relates to the technical field of transformer equipment, and specifically to a protection structure for a transformer. Background Art
[0002] A transformer is a key device in the power system for changing the AC voltage. It realizes the efficient transmission and distribution of electrical energy through the principle of electromagnetic induction, and has many advantages such as strong short-circuit resistance, low noise, stable performance, small volume, high operating efficiency, and low maintenance cost. It is commonly used in various places such as urban power grids, railways, ports, tunnels, mines, power stations, factories, residential communities, and business centers. The design of the protection structure of the transformer aims to ensure its safe operation, extend its service life, and adapt to different installation environments.
[0003] Among them, when the transformer is installed in a mountainous area, there are often falling rocks in the mountainous area, and the falling rocks may hit the transformer. The common protection method usually uses a retaining wall to surround the transformer on all sides, but an inclined plate is usually installed on the top of the transformer to block the crushed stones. When the crushed stones hit the inclined plate, the impact generated may cause the transformer to be subjected to a large vibration, and over a long time, it may cause damage to the transformer. Summary of the Invention
[0004] To solve the above technical problems, the present invention provides a protection structure for a transformer, including a protection housing, and two support rods are fixedly connected to the top of the protection housing; A protection mechanism, a support assembly is fixedly installed on the top of the protection mechanism, and a blocking assembly is rotatably arranged on the top of the support assembly, and the blocking assembly is used to block falling rocks; A buffering mechanism, the buffering mechanism is installed on the top of the protection mechanism and is used to buffer the impact of falling rocks; and A jacking mechanism, the jacking mechanism is located on the top of the protection mechanism and is used to prevent the strong wind from blowing the blocking assembly to swing; Fixed cylinders are fixedly connected to the left and right sides of the two support rods, and spring extrusion rods are slidably connected to the inner walls of the four fixed cylinders, and blocking rods are fixedly connected to the side walls of the four spring extrusion rods; Among them, the falling rocks on the top of the protection housing are blocked by the blocking assembly, and then the impact generated by the falling rocks is buffered by the buffering mechanism. Finally, the jacking mechanism reduces the swinging amplitude of the buffering mechanism, effectively preventing the large vibration generated by the impact of the stones from being transmitted to the protection housing, resulting in a large vibration of the transformer, and over a long time, it may cause damage to the transformer, thereby ensuring the stable operation of the transformer.
[0005] Preferably, the protection mechanism includes: A support assembly, the support assembly is fixedly arranged on the top of the protection housing and is used to protect the transformer; The blocking component is rotatably arranged on the outer wall of the support rod and is used to block the falling rocks from directly impacting the protective shell. Among them, the transformer is installed inside the protective shell. When the falling rocks hit the blocking component, the blocking component will rotate, consuming part of the impact force and converting it into rotational kinetic energy, reducing the impact force of the falling rocks, thereby reducing vibration and preventing the transformer from resonating due to vibration.
[0006] Preferably, the buffering mechanism includes: The absorption component is fixedly arranged on the side wall of the spring extrusion rod through a fixing piece and is used to consume the impact force generated by the falling rocks. The fixing piece includes a sliding frame fixedly connected to the side of the spring extrusion rod away from the blocking rod, and air delivery pipes are all connected through the inner walls of the four fixing cylinders. The extrusion component is fixedly arranged on the outer wall of the fixing cylinder through a pushing piece and is used to increase the gas pressure inside the absorption component. The pushing piece includes a pneumatic frame fixedly connected to the outer wall of the fixing cylinder, and connecting rods are all slidably connected to the inner walls of the four pneumatic frames. Among them, when the blocking component rotates, it will push the absorption component to move. Through the absorption component, the gas is compressed to absorb the residual energy. As the gas pressure increases, after the gas is discharged, the gas pressure increases again. This process is repeated, creating multiple opportunities for energy absorption, reducing the impact of the crushed stones. When the absorption component moves, it will make the extrusion component move. When the gas inside the absorption component is discharged, the gas inside the extrusion component will enter the absorption component, quickly increasing the gas pressure on the right side of the fixing cylinder, reducing the moving distance of the spring extrusion rod squeezing the gas, enabling it to absorb the impact energy more quickly again and shortening the energy absorption cycle.
[0007] Preferably, the jacking mechanism includes: The guiding component is rotatably arranged on the inner wall of the support rod through a rotating piece and is used to control the rotation direction in a strong wind environment. The rotating piece includes a guiding plate rotatably connected to the inner wall of the support rod, and sliding blocks are slidably connected to the left and right sides of the two support rods. The pushing component is slidably arranged on the top of the sliding block through a sliding piece and is used to jack up the blocking component. The sliding piece includes a jacking plate slidably connected to the top of the sliding block, and a second spring return rod is fixedly connected to the side wall of the sliding block. Among them, when there is a strong wind, the strong wind will blow the guiding component to rotate. The guiding component will push the pushing component to rise, enabling the pushing component to push the blocking component to rise, separating the blocking component, reducing the windward area, thereby reducing the swinging amplitude of the blocking component and effectively preventing the large swinging amplitude of the blocking component in strong wind weather, which affects the absorption of the impact force of the stones.
[0008] Preferably, the support assembly includes two rotating plates arranged on the top of the protective housing, and the inner walls of the two rotating plates are rotatably connected to the outer walls of the support rods; The blocking assembly includes sliding plates slidably connected to the inner walls of the rotating plates. Four limiting rods are fixedly connected to the tops of the two sliding plates. The eight limiting rods are grouped in fours, and the inner walls of the two sliding plates are slidably connected to the outer walls of the two groups of limiting rods; Among them, when a falling rock hits the top of the sliding plate, it will impact the sliding plate, and the generated impact force will push the rotating plate to rotate towards the support rod, converting part of the impact force into rotational kinetic energy to block the falling rock and reduce the impact force of the falling rock.
[0009] Preferably, the absorption assembly includes two fixed frames fixedly connected to the bottoms of the rotating plates, and the outer walls of the four fixed frames are slidably connected to the inner walls of the four sliding frames; Communication holes are formed in the inner walls of the four fixed cylinders, and three annular grooves are formed in the outer walls of the four blocking rods; Among them, when the rotating plate rotates, it will drive the fixed frame to move, so that the fixed frame slides in the sliding frame, pushing the sliding frame to move towards the support rod direction, causing the spring pressing rod to move. The spring pressing rod will drive the blocking rod to move. When the blocking rod moves, it will block the communication hole. As the spring pressing rod continues to move, it will compress the gas in the fixed cylinder. The blocking rod will block the movement of the gas, causing the gas pressure to rise, absorbing the impact of the stone. As the spring pressing rod continues to move, the annular groove will move to the position of the communication hole, canceling the blockage of the gas. At this time, the high-pressure gas on the right side of the fixed cylinder will enter the left side of the fixed cylinder through the communication hole, and the gas on the left side will enter the right side of the spring pressing rod through the air pipe, causing the gas pressure to decrease. The spring pressing rod continues to move, and the annular groove will separate from the communication hole. The spring pressing rod will again compress the gas, causing the gas pressure to rise, consuming the impact kinetic energy until the annular groove moves to the position of the communication hole again. In this way, when the crushed stone hits the sliding plate, the rotating plate rotates, converting part of the impact force into rotational kinetic energy, reducing the impact force directly transmitted to the protective housing, and then allowing the gas to be compressed to absorb the residual energy. As the gas pressure increases, after the gas is discharged, the gas pressure increases again. In this way, multiple opportunities for energy absorption are formed, reducing the impact of the crushed stone, reducing the vibration received by the sliding plate, and effectively preventing the large vibration generated by the stone hitting the sliding plate from being transmitted to the protective housing, resulting in a large vibration of the transformer.
[0010] Preferably, the extrusion assembly includes arc-shaped plates slidably connected to the inner walls of the air pressure frames. The side walls of the four arc-shaped plates are fixedly connected to the side walls of the four connecting rods. The side walls of the four sliding frames are fixedly connected to the sides of the four connecting rods away from the arc-shaped plates.
[0011] Preferably, the extrusion assembly further includes a connecting pipe penetrating and connected to the inner wall of the air pressure frame. Concave-convex rods are fixedly connected to the side walls of the four arc-shaped plates. Spring blocking rods are slidably connected to the inner walls of the four connecting pipes. Air delivery grooves are formed in the outer walls of the four spring blocking rods. Among them, when the sliding frame moves towards the support rod, it will also drive the connecting rod, the arc-shaped plate and the concave-convex rod to move. When the concave-convex rod moves, the protrusion of the concave-convex rod will be separated from the spring blocking rod. Since the spring blocking rod was in a compressed state before, the resilience of the spring blocking rod will be released at this time, causing the spring blocking rod to rise, making the air delivery groove rise, so that the bottom of the spring blocking rod contacts the connecting pipe, blocking the flow of the gas in the air pressure frame. As the arc-shaped plate continues to move, it will squeeze the gas in the air pressure frame. At this time, the squeezed gas will be blocked by the spring blocking rod, so the gas pressure will increase. Since the spring extrusion rod and the arc-shaped plate move simultaneously.
[0012] Preferably, the guiding assembly includes two inclined panels fixedly connected to the bottom of the guiding plate. Two spring return rods I are fixedly connected to the tops of the four sliding blocks. Four fixing blocks are fixedly connected to the left and right sides of the two support rods. The inner walls of the eight fixing blocks are slidably connected to the outer walls of the eight spring return rods I. Among them, to solve the problem that in strong wind weather, the strong wind may blow the rotating plate to swing, and in strong wind weather, stones are likely to fall, and the swinging of the rotating plate will affect the absorption of the impact force of the stones. When there is strong wind around the protective shell, the strong wind will blow the guiding plate to rotate, and the guiding plate will drive the inclined panel to rotate, so that the inclined surface of the inclined panel contacts the bottom of the sliding block and jacks up the guiding plate.
[0013] Preferably, the pushing assembly includes a number of flow holes slidably formed in the outer wall of the sliding plate. The outer walls of the four jacking plates are slidably connected to the inner walls of the four spring return rods II. Among them, the rising of the sliding block will drive the jacking plate to rise, so that the jacking plate pushes the sliding plate to rise, separating the sliding plate from the rotating plate, creating a gap between the two. Then the strong wind will flow through the flow holes and the gap between the two, reducing the windward area and reducing the driving force of the strong wind on the sliding plate and the rotating plate, thereby reducing the swinging amplitude of the rotating plate, effectively preventing the large swinging amplitude of the rotating plate in strong wind weather. When a stone impacts on the sliding plate, it may cause the rotation distance of the rotating plate to decrease compared to the stable state, affecting the absorption of the impact force of the stone.
[0014] The present invention has the following beneficial effects: When the present invention is in use, when mountain rockfalls drop and contact the blocking component, they will impact it, thereby driving the blocking component to rotate, converting part of the impact force into rotational kinetic energy, reducing the impact force directly transmitted to the transformer. At the same time, through the absorption component, the gas is compressed to absorb the residual energy. As the gas pressure increases, after the gas is discharged, the gas pressure is increased again, and so on, forming multiple opportunities for energy absorption, reducing the impact of the crushed stones, reducing the vibration received by the sliding plate, and effectively preventing large vibrations generated by the stones hitting the sliding plate from being transmitted to the protective housing, resulting in large vibrations of the transformer.
[0015] When the sliding frame of the present invention moves towards the support rod, the extrusion component extrudes the gas. After the gas in the absorption component is discharged, the gas in the extrusion component will enter the absorption component, causing the gas pressure on the right side of the fixed cylinder to rise rapidly, reducing the moving distance of the spring extrusion rod squeezing the gas, enabling it to absorb the impact energy more quickly again, and shortening the energy absorption cycle.
[0016] To solve the problem that in strong wind weather, the strong wind may blow the rotating plate to swing, and strong wind weather is likely to cause stones to fall, and the swinging of the rotating plate will affect the absorption of the impact force of the stones. When there is strong wind around the protective housing, the strong wind will blow the guiding component to rotate, lift the pushing component, separate the sliding plate from the rotating plate, creating a gap between them. The strong wind will then flow through the flow holes and the gap between them, reducing the windward area and lowering the driving force of the strong wind on the sliding plate and the rotating plate, thereby reducing the swinging amplitude of the rotating plate. Effectively preventing in strong wind weather, the swinging amplitude of the rotating plate is large, and when the stone impacts on the sliding plate, the rotating distance of the rotating plate may be reduced compared to the stable state, affecting the absorption of the impact force of the stone.
[0017] When the impact force of the stone disappears, at this time, the resilience of the spring extrusion rod will be released, causing the spring extrusion rod to return to its original position. It will squeeze the gas on the right side of the spring extrusion rod, enter the left side of the spring extrusion rod through the air pipe. When the blocking rod moves into the communication hole, it will block the flow of the gas. As the spring extrusion rod continues to move, the gas pressure on the right side will increase, slowing down the return speed of the spring extrusion rod, effectively preventing the strong resilience of the spring extrusion rod from causing the rotating plate to quickly return to its original position and then possibly rebound, resulting in the swinging of the rotating plate, generating vibration of the rotating plate, causing resonance, and affecting the stability of the transformer in the protective housing.

Detailed implementation manners
[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the 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.
[0022] Embodiment 1, please refer to Figures 1 - 4 , the present invention is a protection structure for a transformer, including a protection housing 111, and two support rods 112 are fixedly connected to the top of the protection housing 111; Protection mechanism 1, a support assembly 11 is fixedly installed on the top of the protection mechanism 1, and a blocking assembly 12 is rotatably arranged on the top of the support assembly 11, and the blocking assembly 12 is used to block falling stones; Shock mitigation mechanism 2, the shock mitigation mechanism 2 is installed on the top of the protection mechanism 1 for mitigating the impact of falling stones; and Lifting mechanism 3, the lifting mechanism 3 is located on the top of the protection mechanism 1 for preventing strong winds from blowing the blocking assembly 12 to swing; Fixed cylinders 211 are fixedly connected to the left and right sides of the two support rods 112, and spring extrusion rods 212 are slidably connected to the inner walls of the four fixed cylinders 211, and blocking rods 216 are fixedly connected to the side walls of the four spring extrusion rods 212; Among them, the falling stones on the top of the protection housing 111 are blocked by the blocking assembly 12, and then the impact generated by the falling stones is mitigated by the shock mitigation mechanism 2. Finally, the swing amplitude of the shock mitigation mechanism 2 is reduced by the lifting mechanism 3, effectively preventing large vibrations generated by the impact of stones from being transmitted to the protection housing 111, resulting in large vibrations of the transformer. Long-term vibrations may cause damage to the transformer, thereby ensuring the stable operation of the transformer.
[0023] The protection mechanism 1 includes: Support assembly 11, the support assembly 11 is fixedly arranged on the top of the protection housing 111 for protecting the transformer; Blocking assembly 12, the blocking assembly 12 is rotatably arranged on the outer wall of the support rod 112 for blocking falling stones from directly impacting the protection housing 111; Among them, the transformer is installed in the protection housing 111. When falling stones hit the blocking assembly 12, the blocking assembly 12 will rotate, consuming part of the impact force and converting it into rotational kinetic energy, reducing the impact force of the falling stones, thereby reducing vibrations and preventing the transformer from resonating due to vibrations.
[0024] The shock mitigation mechanism 2 includes: Absorption assembly 21, the absorption assembly 21 is fixedly arranged on the side wall of the spring extrusion rod 212 through a fixing member for consuming the impact force generated by falling stones; The fixing member includes a sliding frame 215 fixedly connected to the side of the spring extrusion rod 212 away from the blocking rod 216, and air delivery pipes 213 are connected through the inner walls of the four fixed cylinders 211; Extrusion assembly 22, the extrusion assembly 22 is fixedly arranged on the outer wall of the fixed cylinder 211 through a pushing member for increasing the gas pressure in the absorption assembly 21; The driving member includes a pneumatic frame 221 fixedly connected to the outer wall of the fixed cylinder 211, and a connecting rod 222 is slidably connected to the inner wall of each of the four pneumatic frames 221; Among them, when the blocking component 12 rotates, it will push the absorption component 21 to move. Through the absorption component 21, the gas is compressed to absorb the residual energy. As the gas pressure increases, after the gas is discharged, the gas pressure is increased again. In this way, multiple opportunities for energy absorption are formed, reducing the impact of the crushed stone. When the absorption component 21 moves, it will cause the extrusion component 22 to move. When the gas in the absorption component 21 is discharged, the gas in the extrusion component 22 will enter the absorption component 21, causing the gas pressure on the right side of the fixed cylinder 211 to rise rapidly, reducing the moving distance of the spring extrusion rod 212 squeezing the gas, enabling it to absorb the impact energy more quickly again and shortening the energy absorption cycle.
[0025] The jacking mechanism 3 includes: A guiding component 31, which is rotatably arranged on the inner wall of the support rod 112 through a rotating member and is used to control the rotation direction of the strong wind environment; The rotating member includes a guiding plate 311 rotatably connected to the inner wall of the support rod 112, and sliding blocks 313 are slidably connected to the left and right sides of the two support rods 112; A pushing component 32, which is slidably arranged on the top of the sliding block 313 through a sliding member and is used to jack up the blocking component 12; The sliding member includes a jacking plate 321 slidably connected to the top of the sliding block 313, and a spring return rod two 322 is fixedly connected to the side wall of the sliding block 313; Among them, when there is strong wind weather, the strong wind will blow the guiding component 31 to rotate. The guiding component 31 will push the pushing component 32 to rise, causing the pushing component 32 to push the blocking component 12 to rise, separating the blocking component 12, reducing the windward area, thereby reducing the swinging amplitude of the blocking component 12 and effectively preventing the large swinging amplitude of the blocking component 12 in strong wind weather from affecting the absorption of the impact force of the stone.
[0026] Embodiment 2, please refer to Figures 1 - 10 , the present invention is a protection structure for a transformer. On the basis of Example 1, the support component 11 includes two rotating plates 113 arranged on the top of the protection shell 111, and the inner walls of the two rotating plates 113 are rotatably connected to the outer wall of the support rod 112; The blocking component 12 includes a sliding plate 121 slidably connected to the inner wall of the rotating plate 113. Four limiting rods 122 are fixedly connected to the top of each of the two sliding plates 121. The eight limiting rods 122 are grouped in fours, and the inner walls of the two sliding plates 121 are slidably connected to the outer walls of the two groups of limiting rods 122; Among them, when the falling rock lands on the top of the sliding plate 121, it will impact the sliding plate 121, and the generated impact force will push the rotating plate 113 to rotate towards the support rod 112, converting part of the impact force into rotational kinetic energy to block the falling rock and reduce the impact force of the falling rock.
[0027] The absorption component 21 includes two fixing frames 214 fixedly connected to the bottom of the rotating plate 113. The outer walls of the four fixing frames 214 are slidably connected to the inner walls of the four sliding frames 215; Communication holes 218 are provided in the inner walls of the four fixing cylinders 211, and three annular grooves 217 are provided in the outer walls of the four blocking rods 216; Among them, when the rotating plate 113 rotates, it will drive the fixing frame 214 to move, causing the fixing frame 214 to slide within the sliding frame 215, pushing the sliding frame 215 towards the support rod 112, causing the spring pressing rod 212 to move. The spring pressing rod 212 will drive the blocking rod 216 to move. When the blocking rod 216 moves, it will block the communication hole 218. As the spring pressing rod 212 continues to move, it will compress the gas in the fixing cylinder 211. The blocking rod 216 will block the movement of the gas, causing the gas pressure to increase, absorbing the impact of the stone. As the spring pressing rod 212 continues to move, the annular groove 217 will move to the position of the communication hole 218, canceling the blockage of the gas. At this time, the high-pressure gas on the right side of the fixing cylinder 211 will enter the left side of the fixing cylinder 211 through the communication hole 218, and the gas on the left side will enter the right side of the spring pressing rod 212 through the air pipe 213, causing the gas pressure to decrease. As the spring pressing rod 212 continues to move, the annular groove 217 will separate from the communication hole 218, and the spring pressing rod 212 will compress the gas again, causing the gas pressure to increase, consuming the impact kinetic energy until the annular groove 217 moves to the position of the communication hole 218 again. This process repeats. When the crushed stone impacts the sliding plate 121, it causes the rotating plate 113 to rotate, converting part of the impact force into rotational kinetic energy, reducing the impact force directly transmitted to the protective housing 111. Then, the gas is compressed to absorb the residual energy. As the gas pressure increases, after the gas is discharged, the gas pressure increases again. This process repeats, creating multiple opportunities for energy absorption, reducing the impact of the crushed stone, and reducing the vibration received by the sliding plate 121, effectively preventing the large vibration generated by the stone impacting the sliding plate 121 from being transmitted to the protective housing 111, resulting in a large vibration of the transformer.
[0028] The extrusion component 22 includes an arc-shaped plate 223 slidably connected to the inner wall of the air pressure frame 221. The side walls of the four arc-shaped plates 223 are fixedly connected to the side walls of the four connecting rods 222. The side walls of the four sliding frames 215 are fixedly connected to the sides of the four connecting rods 222 away from the arc-shaped plate 223.
[0029] The extrusion assembly 22 further includes a communication pipe 225 penetrating and connected to the inner wall of the air pressure frame 221. Concave-convex rods 224 are fixedly connected to the side walls of the four arc-shaped plates 223. Spring blocking rods 226 are slidably connected to the inner walls of the four communication pipes 225. Air delivery grooves 227 are formed in the outer walls of the four spring blocking rods 226. Among them, when the sliding frame 215 moves towards the support rod 112, it will also drive the connecting rod 222, the arc-shaped plate 223 and the concave-convex rod 224 to move. When the concave-convex rod 224 moves, the protrusion of the concave-convex rod 224 will be separated from the spring blocking rod 226. Since the spring blocking rod 226 was in a compressed state before, the resilience of the spring blocking rod 226 will be released at this time, causing the spring blocking rod 226 to rise, making the air delivery groove 227 rise, so that the bottom of the spring blocking rod 226 contacts the communication pipe 225, blocking the flow of the gas in the air pressure frame 221. As the arc-shaped plate 223 continues to move, it will squeeze the gas in the air pressure frame 221. At this time, the squeezed gas will be blocked by the spring blocking rod 226, so the gas pressure will increase. Since the spring extrusion rod 212 and the arc-shaped plate 223 move simultaneously.
[0030] The guiding assembly 31 includes two inclined panels 312 fixedly connected to the bottom of the guiding plate 311. Two spring return rods one 315 are fixedly connected to the tops of the four sliding blocks 313. Four fixing blocks 314 are fixedly connected to the left and right sides of the two support rods 112. The inner walls of the eight fixing blocks 314 are slidably connected to the outer walls of the eight spring return rods one 315. Among them, to solve the problem that in strong wind weather, the strong wind may blow the rotating plate 113 to swing, and in strong wind weather, it is easy for stones to fall, and the swinging of the rotating plate 113 will affect the absorption of the impact force of the stones. When there is strong wind around the protective housing 111, the strong wind will blow the guiding plate 311 to rotate. The guiding plate 311 will drive the inclined panel 312 to rotate, so that the inclined surface of the inclined panel 312 contacts the bottom of the sliding block 313, lifting the guiding plate 311.
[0031] The pushing assembly 32 includes a number of flow holes 323 slidably formed in the outer wall of the sliding plate 121. The outer walls of the four lifting plates 321 are slidably connected to the inner walls of the four spring return rods two 322. Among them, when the sliding block 313 rises, it will drive the jacking plate 321 to rise, causing the jacking plate 321 to push the sliding plate 121 to rise. As shown in Figure 10, the sliding plate 121 is separated from the rotating plate 113, creating a gap between them. Strong wind will then flow through the flow hole 323 and the gap between the two, reducing the windward area and lowering the driving force of the strong wind on the sliding plate 121 and the rotating plate 113. This thereby reduces the swing amplitude of the rotating plate 113 and effectively prevents the large swing amplitude of the rotating plate 113 in strong wind weather. When a stone impacts the sliding plate 121, it may cause the rotation distance of the rotating plate 113 to decrease compared to the stable state, affecting the absorption of the impact force of the stone.
[0032] The quantity of the above components is not limited, and those skilled in the relevant art can freely set it 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 the present invention is in use, the transformer is installed in the protective housing 111 for protection. When a mountain rock falls and contacts the sliding plate 121, it will impact the sliding plate 121, generating an impact on the sliding plate 121, thereby pushing the rotating plate 113 to rotate towards the support rod 112, converting part of the impact force into rotational kinetic energy. When the rotating plate 113 rotates, it will drive the fixed frame 214 to move, causing the fixed frame 214 to slide within the sliding frame 215, pushing the sliding frame 215 towards the support rod 112, causing the spring pressing rod 212 to move. The spring pressing rod 212 will drive the blocking rod 216 to move. When the blocking rod 216 moves, it will block the communication hole 218. As the spring pressing rod 212 continues to move, it will compress the gas within the fixed cylinder 211. The blocking rod 216 will block the movement of the gas, causing the gas pressure to increase and absorb the impact of the stone. As the spring pressing rod 212 continues to move, the annular groove 217 will move to the position of the communication hole 218, canceling the blockage of the gas. At this time, the high-pressure gas on the right side of the fixed cylinder 211 will enter the left side of the fixed cylinder 211 through the communication hole 218. The gas on the left side will enter the right side of the spring pressing rod 212 through the air pipe 213, causing the gas pressure to decrease. As the spring pressing rod 212 continues to move, the annular groove 217 will separate from the communication hole 218, and the spring pressing rod 212 will again compress the gas, causing the gas pressure to increase and consuming the impact kinetic energy until the annular groove 217 moves to the position of the communication hole 218 again, and so on. When the crushed stone impacts the sliding plate 121, the rotating plate 113 rotates, converting part of the impact force into rotational kinetic energy, reducing the impact force directly transmitted to the protective housing 111. Then, the gas is compressed to absorb the residual energy. As the gas pressure increases, after the gas is discharged, the gas pressure increases again, and so on, creating multiple opportunities for energy absorption, reducing the impact of the crushed stone, reducing the vibration received by the sliding plate 121, effectively preventing the large vibration generated by the stone impacting the sliding plate 121 from being transmitted to the protective housing 111, resulting in a large vibration of the transformer; In the above method, compared with the gas being unidirectionally compressed, causing the pressure to continuously increase, the compression amplitude will gradually decrease, resulting in a gradual increase in its rigidity, affecting the absorption of the impact force, and may not have a good absorption effect on a strong impact force; Secondly, when the sliding carriage 215 moves towards the support rod 112, it will also drive the connecting rod 222, the arc-shaped plate 223 and the concave-convex rod 224 to move. When the concave-convex rod 224 moves, the protrusion of the concave-convex rod 224 will be separated from the spring blocking rod 226. Since the spring blocking rod 226 was in a compressed state before, the resilience of the spring blocking rod 226 will be released at this time, causing the spring blocking rod 226 to rise, making the air delivery groove 227 rise, so that the bottom of the spring blocking rod 226 contacts the communicating pipe 225, blocking the flow of the gas in the air pressure frame 221. As the arc-shaped plate 223 continues to move, it will squeeze the gas in the air pressure frame 221. At this time, the squeezed gas will be blocked by the spring blocking rod 226, so the gas pressure will increase. Since the spring pressing rod 212 and the arc-shaped plate 223 move simultaneously, when the annular groove 217 is separated from the communication hole 218, the protrusion of the concave-convex rod 224 will contact the spring blocking rod 226, squeezing the spring blocking rod 226 to descend, causing it to accumulate resilience, making the annular groove 217 descend, and separating the bottom of the spring blocking rod 226 from the communicating pipe 225. For example: Figure 5 As shown, the high-pressure gas in the fixed cylinder 211 can enter the right side of the fixed cylinder 211, rapidly increasing the gas pressure on the right side of the fixed cylinder 211, reducing the moving distance of the spring pressing rod 212 squeezing the gas, enabling it to absorb the impact energy more quickly again, and shortening the energy absorption cycle; Secondly, to solve the problem that in strong wind weather, the strong wind may blow the rotating plate 113 to swing, and in strong wind weather, stones are likely to fall, and the swing of the rotating plate 113 will affect the absorption of the impact force of the stones. When there is strong wind around the protective housing 111, the strong wind will blow the guide plate 311 to rotate. The guide plate 311 will drive the inclined panel 312 to rotate, making the inclined surface of the inclined panel 312 contact the bottom of the sliding block 313, lifting the guide plate 311, squeezing the first spring return rod 315, causing the first spring return rod 315 to accumulate resilience. The rising of the sliding block 313 will drive the jacking plate 321 to rise, making the jacking plate 321 push the sliding plate 121 to rise. As shown in Figure 10, the sliding plate 121 is separated from the rotating plate 113, creating a gap between them. The strong wind will flow through the flow holes 323 and the gap between them, reducing the windward area and lowering the driving force of the strong wind on the sliding plate 121 and the rotating plate 113, thereby reducing the swing amplitude of the rotating plate 113, effectively preventing the large swing amplitude of the rotating plate 113 in strong wind weather. When a stone impacts on the sliding plate 121, it may cause the rotation distance of the rotating plate 113 to decrease compared to the stable state, affecting the absorption of the impact force of the stone; Among them, when in a strong wind environment and a stone contacts the rotating plate 113, the sliding plate 121 will be impacted and descend, squeezing the jacking plate 321, causing the jacking plate 321 to move towards the support rod 112, squeezing the spring return rod two 322, enabling it to accumulate resilience until the sliding plate 121 contacts the rotating plate 113, pushing the rotating plate 113 to rotate and absorb the impact generated by the stone. During the rotation of the sliding plate 121, the sliding plate 121 will continuously squeeze the jacking plate 321 to move; Among them, since the contact surface between the inclined panel 312 and the bottom of the jacking plate 321 is an inclined surface, when the strong wind stops, the force pushing the guide plate 311 disappears, and the resilience of the spring return rod one 315 will be released, causing the sliding block 313 to descend, enabling the bottom of the sliding block 313 to squeeze the inclined surface of the inclined panel 312, causing the guide plate 311 to rotate, separating the inclined panel 312 from the guide plate 311, and causing the guide plate 311 to return to its original position; Secondly, when the impact force of the stone disappears, at this time, the resilience of the spring extrusion rod 212 will be released, causing the spring extrusion rod 212 to return to its original position. By pushing the fixed frame 214 to move through the sliding frame 215, the support rod 112 returns to its original position and rotates. Among them, when the spring extrusion rod 212 returns to its original position, it will squeeze the gas on the right side of the spring extrusion rod 212, enter the left side of the spring extrusion rod 212 through the air delivery pipe 213. When the blocking rod 216 moves into the communication hole 218, it will block the flow of gas. When the spring extrusion rod 212 continues to move, the gas pressure on the right side of the spring extrusion rod 212 will increase, slowing down the return speed of the spring extrusion rod 212 until the annular groove 217 moves to the position of the communication hole 218 again, enabling the gas to flow. By slowing down the return speed of the spring extrusion rod 212, it effectively prevents the spring extrusion rod 212 from having a strong resilience, resulting in the rapid return of the rotating plate 113 and then potentially rebounding again, causing the rotating plate 113 to swing, generating vibration of the rotating plate 113, causing resonance, and affecting the stability of the transformer within the protective housing 111.
