A dry-type transformer is fixedly connected to the inner wall of the protective frame, and a protective cover is fixedly connected to the top of the dry-type transformer. A guide frame is fixedly connected to the top of the protective cover.

Description

Technical Field

[0001] This invention relates to the field of dry-type transformer equipment technology, specifically to a dry-type transformer with an incoming line protection structure. Background Technology

[0002] A dry-type transformer is a power transformer that does not use liquid insulating media (such as transformer oil), but relies on solid insulating materials (such as epoxy resin and glass fiber) and air for insulation and heat dissipation. Its design has the advantages of high safety, environmental protection and adaptability to complex environments, and it is widely used in civil buildings, industrial facilities, new energy and other fields. The core feature of the incoming line protection structure is to enhance the safety protection of the transformer input end through a specially designed incoming line section.

[0003] When dry-type transformers are used outdoors, protective covers are often used to protect the transformer's input terminals. Since the input terminals generate heat when generating electricity, fans are usually used to dissipate the heat. However, when transformers are used in coastal areas, the humidity is high. The fans may draw in humid air from outside and have direct contact with the terminals. Direct contact between humid air and terminals may cause corrosion. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a dry-type transformer with an incoming line protection structure, including a protective frame, a dry-type transformer fixedly connected to the inner wall of the protective frame, and a protective cover fixedly connected to the top of the dry-type transformer. The protection mechanism has a protective component fixedly installed on its inner wall, and a cooling component is installed on the top of the protective component. The protective component is used to protect the dry-type transformer. A heat-conducting mechanism, mounted on top of the protective assembly, is used to guide heat flow; and A cleaning mechanism, located on top of the protective assembly, is used to clean the surface of the heat-conducting mechanism; A flow guide frame is fixedly connected to the top of the protective cover, a concave-convex plate is slidably connected to the inner wall of the flow guide frame, and a heat conduction plate is fixedly connected to the inner wall of the flow guide frame. The system protects the dry-type transformer through a protective mechanism, and then guides the heat generated at the input of the dry-type transformer to flow towards the heat-conducting plate through a heat-conducting mechanism to dissipate heat. This reduces the direct contact between the external humid air and the wiring parts, keeping the wiring parts dry and effectively preventing humid air from contacting the wiring parts, which can easily lead to corrosion of the wiring parts and affect the transmission effect of the wiring parts. Finally, the cleaning mechanism removes the condensate generated by heat dissipation.

[0005] Preferably, the protection mechanism includes: The protective component is fixedly installed on the outer wall of the protective component and the inner wall of the protective frame to protect the dry-type transformer. A cooling component is fixedly installed on the side wall of the dry-type transformer to dissipate heat from the inlet section of the dry-type transformer.

[0006] Preferably, the heat-conducting mechanism includes: The guiding component is fixedly installed on the inner wall of the protective cover by fasteners and is used to guide the gas flow. The fasteners include a pneumatic frame fixedly connected to the inner wall of the protective cover, and an electric telescopic rod fixedly connected to the inner wall of the protective cover. The pushing component is slidably mounted on the inner wall of the pneumatic frame via a slider, and is used to compress gas; The sliding component includes an extrusion plate that is slidably connected to the inner wall of the pneumatic frame, and a baffle plate that is slidably connected to the inner wall of the pneumatic frame. The system guides the flow of hot air within the protective frame through a guiding component, which in turn absorbs heat through a heat-conducting plate. Then, a cooling component cools the heat-conducting plate, and a pushing component accelerates the airflow generated by the cooling component, reducing direct contact between the external humid air and the wiring parts, keeping the wiring parts dry and maintaining the stability of power transmission.

[0007] Preferably, the cleaning mechanism includes: The collection component is fixedly installed on the side wall of the guide frame by a support member and is used to collect the condensate generated during cooling. The support includes two fixed frames that are fixedly connected to the front and back of the guide frame, and ten connecting rods are fixedly connected to the top of the concave-convex plate. The cleaning component is slidably mounted on top of the heat-conducting plate via a connector and is used to clean the surface of the heat-conducting plate. The connector includes two scrapers slidably connected to the top of the heat-conducting plate, and five push rods slidably connected to the inner wall of each scraper; When the component is moved, the collection component descends to remove condensation from the bottom of the heat-conducting plate, effectively preventing water droplets from falling onto the wiring area during the alternating hot and cold processes. At the same time, it also moves the cleaning component to clean the top of the heat-conducting plate, effectively preventing the salt spray present in the humid air of coastal areas from adhering to the surface of the heat-conducting plate and forming an adhesion layer due to prolonged impact from humid air.

[0008] Preferably, the cooling component includes three terminals fixedly connected to the side wall of the dry-type transformer, a fan fixedly connected to the inner wall of the flow guide frame, and the terminals for connecting to the incoming cable.

[0009] Preferably, the guide assembly includes several through holes opened in the inner wall of the pneumatic frame, the top output end of the electric telescopic rod is fixedly connected to the bottom of the extrusion plate, and the shape of the first concave-convex plate is wavy. The process involves extending an electric telescopic rod, which pushes a compression plate upwards, compressing the gas within the pressure frame. The compressed gas is initially blocked by a baffle plate, causing the gas pressure to rise. As the compression plate continues to move, the gas pressure gradually increases, eventually pushing the baffle plate away from the pressure frame. This releases the baffle plate, allowing the high-pressure gas to be ejected towards the terminals. This causes the heat on the terminal surface to transfer rapidly with the gas, flowing towards the heat-conducting plate for absorption. Simultaneously, a fan is activated to draw in humidified air from outside. The airflow flows within the guide frame, causing it to flow across the surface of the convex and concave plate. The wavy shape of the convex and concave plate disturbs the airflow, forcing it into localized turbulence and irregular flow. This allows the airflow to fully contact the surface of the heat-conducting plate, carrying away heat and cooling it. The heat-conducting plate absorbs heat generated by the terminals, and the fan further cools the plate, reducing direct contact between humid air and the terminals, keeping them dry and effectively preventing corrosion and ensuring optimal transmission performance.

[0010] Preferably, the pushing component includes three L-shaped plates fixedly connected to the top of the pneumatic frame, and three spring return rods are fixedly connected to the top of the blocking plate. The outer walls of the three spring return rods are slidably connected to the inner walls of the three L-shaped plates.

[0011] Preferably, the pushing assembly further includes a lifting rod fixedly connected to the top of the extrusion plate, the outer wall of the lifting rod being slidably connected to the inner wall of the extrusion plate, and a rocker plate being rotatably connected to the inner wall of the guide frame; A spring reset rod 2 is fixedly connected to the top of the concave-convex plate 1, and the outer wall of the spring reset rod 2 is slidably connected to the inner wall of the guide frame. When the extrusion plate rises, it drives the lifting rod to rise, which in turn pushes the rocker to rotate. This causes the side of the rocker that contacts the lifting rod to rise, while the other side falls. The falling side pushes the first concave-convex plate down, squeezing the second spring return rod, which accumulates rebound force. This brings the first concave-convex plate closer to the heat-conducting plate, reducing the distance between them. As the distance decreases, the gas flow velocity increases when passing through the narrow section. This increased airflow velocity disrupts the thermal boundary layer of the heat-conducting plate, making heat transfer easier. This effectively prevents the high-pressure gas inside the pneumatic frame from carrying away the heat from the terminal surface, which would otherwise cause the heat-conducting plate to absorb too much heat and make it difficult for the airflow to quickly reduce the heat of the heat-conducting plate, leading to heat accumulation.

[0012] Preferably, the collecting assembly includes five pushers slidably connected to the inner wall of the fixed frame, each of the ten pushers having a connecting rod rotatably connected to its side wall, and each of the ten connecting rods having its inner wall rotatably connected to the bottom of the ten connecting rods. Two U-shaped frames are slidably connected to the inner walls of the two fixed frames. Ten push frames are grouped in groups of five. The side walls of the two U-shaped frames are fixedly connected to the side walls of the two groups of push frames. Five drain pipes are connected through the inner walls of the two U-shaped frames. The ten drain pipes are grouped in sets of five, and the inner walls of the two fixed frames are slidably connected to the outer walls of the two sets of drain pipes. To address the issue of condensation that may occur at the bottom of the heat-conducting plate during cooling, potentially causing water droplets to fall onto the terminal block surface, the design incorporates a mechanism where the convex and concave plates descend, causing the connecting rod to descend as well. This connecting rod then rotates the linkage, which in turn moves the pusher frame, causing the U-shaped frame to move and contact the bottom of the heat-conducting plate. The U-shaped frame then scrapes away any condensed water droplets, which fall into the U-shaped frame and accumulate there. Finally, the water droplets are drained through a drain pipe. This design effectively prevents condensation at the bottom of the heat-conducting plate during the cooling process, ensuring that the terminal block surface remains dry.

[0013] Preferably, the cleaning assembly includes a spring rod fixedly connected to the side wall of the scraper, two sliding sleeves slidably connected to the inner wall of the guide frame, and the outer walls of the two spring rods slidably connected to the inner walls of the two sliding sleeves. The side walls of the ten push rods are fixedly connected to the side walls of the ten push frames, and the outer walls of the ten push rods are slidably connected to the inner wall of the guide frame. The inner wall of the guide frame is fixedly connected with two concave and convex plates. When the pusher moves, it drives the pusher rod to move, which in turn moves the scraper and the sliding sleeve and spring rod. When the spring rod moves from the concave position to the convex position of the second concave-convex plate, it is compressed, accumulating rebound force and pushing the scraper to move laterally. As the spring rod continues to move, it will contact the concave position of the second concave-convex plate again, allowing the scraper to return to its original position until the spring rod contacts the convex position of the second concave-convex plate again. This process repeats, allowing the scraper to move laterally back and forth, thoroughly scraping away the deposits on the top of the heat-conducting plate. This effectively prevents the salt spray present in the humid air of coastal areas from causing the surface of the heat-conducting plate to be impacted by humid air for a long time, resulting in salt spray adhering to the surface of the heat-conducting plate and forming an adhesion layer, which affects the heat transfer of the heat-conducting plate and the heat dissipation effect of the airflow on the heat-conducting plate.

[0014] The present invention has the following beneficial effects: (1) When the present invention is used, when it is necessary to cool down the terminal block, the electric telescopic rod is activated to extend and push the guide component to squeeze the gas and spray it onto the terminal block. This causes the heat on the surface of the terminal block to be transferred quickly towards the heat conduction plate with the gas, so that the heat is absorbed by the heat conduction plate. At this time, the cooling component is activated to draw in external humid air. The airflow flows on the surface of the concave-convex plate. Since the shape of the concave-convex plate is wavy, it will disturb the airflow and fully contact the surface of the heat conduction plate, taking away the heat on the surface of the heat conduction plate. This reduces the direct contact between the external humid air and the terminal block, keeping the terminal block dry and effectively preventing the humid air from contacting the terminal block, which can easily lead to corrosion of the terminal block and affect the transmission effect of the terminal block.

[0015] (2) When the extrusion plate rises, it will drive the pushing component to rise and push the concave-convex plate to fall, so that the concave-convex plate is close to the heat-conducting plate and the distance between them is reduced. At this time, when the airflow generated by the fan passes through the guide frame, the flow rate will increase. When the extrusion plate returns to its original position, the concave-convex plate will rise, which will slow down the airflow speed and intermittently increase the flow speed of the airflow. The increased airflow speed will destroy the thermal boundary layer of the heat-conducting plate, making it easier for heat to be transferred. When the flow rate slows down, the thermal boundary layer gradually forms again. This repeated action, compared with a constant flow rate, will enhance the heat exchange of the heat-conducting plate and effectively prevent the high-pressure gas in the air pressure frame from carrying away the heat on the surface of the terminal block, which would cause the heat-conducting plate to absorb too much heat and make it difficult for the airflow to quickly reduce the heat of the heat-conducting plate, causing the heat of the heat-conducting plate to accumulate.

[0016] (3) In order to solve the problem that water droplets may condense on the bottom of the heat-conducting plate during the cooling process of the heat-conducting plate and fall onto the surface of the terminal, the present invention causes the connecting rod to descend when the concave and convex plates descend, which in turn causes the connecting rod to push the push frame to move, which in turn causes the U-shaped frame to move and contact the bottom of the heat-conducting plate. This scrapes away the condensed water droplets on the bottom of the heat-conducting plate and the water droplets fall into the U-shaped frame. This effectively prevents water droplets from condensing on the bottom of the heat-conducting plate and falling onto the surface of the terminal during the cooling process, thus preventing the surface of the terminal from becoming damp.

[0017] (4) When the pusher moves, the pusher rod moves, which in turn pushes the scraper to move, causing the sliding sleeve and spring rod to move. This causes the spring rod to be squeezed, pushing the scraper to move laterally and effectively scraping off the deposits on the top of the heat-conducting plate. This effectively prevents the salt spray in the humid air of coastal areas from impacting the surface of the heat-conducting plate for a long time, causing the salt spray to adhere to the surface of the heat-conducting plate and form an adhesion layer, which affects the heat transfer of the heat-conducting plate and the heat dissipation effect of the airflow on the heat-conducting plate.

[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 a dry-type transformer with an incoming line protection structure, including a protective frame 111, a dry-type transformer 112 fixedly connected to the inner wall of the protective frame 111, and a protective cover 113 fixedly connected to the top of the dry-type transformer 112. The protection mechanism 1 has a protective component 11 fixedly installed on its inner wall and a cooling component 12 installed on its top. The protective component 11 is used to protect the dry-type transformer 112. Heat conduction mechanism 2, mounted on top of protective assembly 11, is used to guide heat flow; and Cleaning mechanism 3, located on top of protective assembly 11, is used to clean the surface of heat conduction mechanism 2; A flow guide frame 211 is fixedly connected to the top of the protective cover 113, a concave-convex plate 212 is slidably connected to the inner wall of the flow guide frame 211, and a heat conduction plate 213 is fixedly connected to the inner wall of the flow guide frame 211. The dry-type transformer 112 is protected by the protection mechanism 1, and the heat generated at the inlet of the dry-type transformer 112 is guided by the heat conduction mechanism 2 to flow towards the heat conduction plate 213 for heat dissipation. This reduces the direct contact between the external humid air and the wiring parts, keeping the wiring parts dry and effectively preventing humid air from contacting the wiring parts, which could easily lead to corrosion of the wiring parts and affect the transmission effect of the wiring parts. Finally, the condensate generated by heat dissipation is removed by the cleaning mechanism 3.

[0023] Protection agency 1 includes: The protective component 11 is fixedly installed on the outer wall of the protective component 111 and the inner wall of the protective frame 111 to protect the dry-type transformer 112. Cooling component 12 is fixedly installed on the side wall of dry transformer 112 and is used to dissipate heat from the inlet of dry transformer 112.

[0024] The heat conduction mechanism 2 includes: The guide component 21 is fixedly installed on the inner wall of the protective cover 113 by a fastener and is used to guide the gas flow. The fasteners include a pneumatic frame 214 fixedly connected to the inner wall of the protective cover 113, and an electric telescopic rod 215 fixedly connected to the inner wall of the protective cover 113. Push component 22 is slidably disposed on the inner wall of the pneumatic frame 214 via a slider, and is used to compress gas; The sliding component includes an extrusion plate 221 that is slidably connected to the inner wall of the pneumatic frame 214, and a baffle plate 222 that is slidably connected to the inner wall of the pneumatic frame 214. Specifically, the hot air inside the protective frame 111 is guided by the guiding component 21, which works with the heat-conducting plate 213 to absorb heat. Then, the heat-conducting plate 213 is cooled by the cooling component 12. The airflow speed generated by the cooling component 12 is increased by the pushing component 22, which reduces the direct contact between the external humid air and the wiring part, keeps the wiring part dry, and maintains the stability of power transmission.

[0025] Cleaning mechanism 3 includes: The collection component 31 is fixedly installed on the side wall of the guide frame 211 by a support member, and is used to collect the condensate generated during cooling. The support includes two fixed frames 311 fixedly connected to the front and back of the guide frame 211, and ten connecting rods 312 fixedly connected to the top of the concave-convex plate 212. Cleaning component 32 is slidably mounted on top of heat conduction plate 213 via a connector and is used to clean the surface of heat conduction plate 213; The connector includes two scrapers 321 that are slidably connected to the top of the heat-conducting plate 213, and five push rods 322 are slidably connected to the inner wall of each scraper 321; When the component 22 is moved, the collecting component 31 will descend to remove the condensation generated at the bottom of the heat-conducting plate 213, effectively preventing water droplets from condensing at the bottom of the heat-conducting plate 213 during the alternating hot and cold process and falling onto the wiring area. At the same time, it will also move the cleaning component 32 to clean the top of the heat-conducting plate 213, effectively preventing the salt spray present in the humid air of coastal areas from being impacted by humid air for a long time, causing the salt spray to adhere to the surface of the heat-conducting plate 213 and form an adhesion layer.

[0026] Example 2, please refer to Figures 1-9 The present invention is a dry-type transformer with an incoming line protection structure. Based on Example 1, the cooling component 12 includes three terminals 121 fixedly connected to the side wall of the dry-type transformer 112, and a fan 122 fixedly connected to the inner wall of the flow guide frame 211. The terminals 121 are used to connect to the incoming line cable.

[0027] The guide component 21 includes several connecting holes 216 opened in the inner wall of the pneumatic frame 214, the top output end of the electric telescopic rod 215 is fixedly connected to the bottom of the extrusion plate 221, and the shape of the concave-convex plate 212 is wavy. In this process, by activating the electric telescopic rod 215 to extend, the extrusion plate 221 is pushed upward, causing the extrusion plate 221 to compress the gas inside the pneumatic frame 214. At this time, the compressed gas is blocked by the baffle plate 222, thus increasing the gas pressure. As the extrusion plate 221 continues to move, the gas pressure gradually increases, and the high-pressure gas inside the pneumatic frame 214 pushes the baffle plate 222 to move, causing the baffle plate 222 to separate from the pneumatic frame 214, thus removing the obstruction to the gas. The high-pressure gas is then ejected towards the terminal 121, causing the heat on the surface of the terminal 121 to be quickly transferred with the gas and flow towards the heat-conducting plate 213, where the heat is absorbed. At this time, the fan 122 is activated to draw in external humid air. The airflow flows within the guide frame 211, causing the airflow to flow on the surface of the convex and concave plate 212. Due to the wavy shape of the convex and concave plate 212, the airflow is disturbed, forcing the airflow to generate local turbulence and causing the airflow to flow irregularly. This allows the airflow to fully contact the surface of the heat-conducting plate 213, carrying away the heat from the surface of the heat-conducting plate 213 and cooling the heat-conducting plate 213. The heat-conducting plate 213 absorbs the heat generated by the terminal 121, and the fan 122 further cools the heat-conducting plate 213, reducing direct contact between the external humid air and the terminal 121, keeping the terminal 121 dry, and effectively preventing humid air from contacting the terminal 121, which could easily lead to corrosion of the terminal 121 and affect the transmission effect of the terminal 121.

[0028] The pushing assembly 22 includes three L-shaped plates 223 fixedly connected to the top of the pneumatic frame 214. Three spring return rods 224 are fixedly connected to the top of the blocking plate 222. The outer walls of the three spring return rods 224 are slidably connected to the inner walls of the three L-shaped plates 223.

[0029] The pushing component 22 also includes a lifting rod 225 fixedly connected to the top of the extrusion plate 221. The outer wall of the lifting rod 225 is slidably connected to the inner wall of the extrusion plate 221, and a rocker plate 226 is rotatably connected to the inner wall of the guide frame 211. A spring reset rod 227 is fixedly connected to the top of the concave-convex plate 212, and the outer wall of the spring reset rod 227 is slidably connected to the inner wall of the guide frame 211. When the extrusion plate 221 rises, it drives the lifting rod 225 to rise, causing the lifting rod 225 to push the rocker 226 to rotate. This causes the side of the rocker 226 that contacts the lifting rod 225 to rise, while the other side falls. The falling side pushes the first concave-convex plate 212 to fall, compressing the second spring return rod 227 and accumulating its rebound force. This causes the first concave-convex plate 212 to approach the heat-conducting plate 213, reducing the distance between them. When the distance between them decreases, the gas flow velocity increases when passing through the narrow part. The increased airflow velocity will damage the thermal boundary layer of the heat-conducting plate 213, making heat transfer easier. This effectively prevents the high-pressure gas in the air pressure frame 214 from carrying away the heat from the surface of the terminal 121, which would cause the heat-conducting plate 213 to absorb too much heat. The airflow would then be unable to quickly reduce the heat of the heat-conducting plate 213, causing heat accumulation in the heat-conducting plate 213.

[0030] The collecting component 31 includes five pushers 313 slidably connected to the inner wall of the fixed frame 311, and each of the ten pushers 313 is rotatably connected to a connecting rod 314 on its side wall. The inner wall of each of the ten connecting rods 314 is rotatably connected to the bottom of ten connecting rods 312. Two U-shaped frames 315 are slidably connected to the inner walls of the two fixed frames 311, and ten pushers 313 are grouped in groups of five. The side walls of the two U-shaped frames 315 are fixedly connected to the side walls of the two groups of pushers 313, and five drain pipes 316 are connected through the inner walls of the two U-shaped frames 315. Ten drain pipes 316 are grouped in fives, and the inner walls of the two fixed frames 311 are slidably connected to the outer walls of the two groups of drain pipes 316. To address the issue of condensation that may occur at the bottom of the heat-conducting plate 213 during cooling, potentially causing water droplets to fall onto the surface of the terminal 121, the connecting rod 312 descends as the concave-convex plate 212 descends. This causes the connecting rod 312 to push the connecting rod 314 to rotate, which in turn moves the pusher frame 313, causing the U-shaped frame 315 to move. The U-shaped frame 315 then contacts the bottom of the heat-conducting plate 213, scraping away any condensed water droplets. The water droplets fall into the U-shaped frame 315, where they gather together and are finally drained through the drain pipe 316. This effectively prevents condensation at the bottom of the heat-conducting plate 213 during the cooling process, thus preventing the terminal 121 from becoming damp.

[0031] The cleaning component 32 includes a spring rod 324 fixedly connected to the side wall of the scraper 321, and two sliding sleeves 323 slidably connected to the inner wall of the guide frame 211. The outer walls of the two spring rods 324 are slidably connected to the inner walls of the two sliding sleeves 323. The side walls of the ten push rods 322 are all fixedly connected to the side walls of the ten push frames 313, and the outer walls of the ten push rods 322 are all slidably connected to the inner wall of the guide frame 211. The inner wall of the guide frame 211 is fixedly connected with a concave-convex plate 325. When the pusher frame 313 moves, it drives the push rod 322 to move, causing the push rod 322 to push the scraper 321 to move, which in turn drives the sliding sleeve 323 and the spring rod 324 to move. When the spring rod 324 moves from the recessed position of the second concave-convex plate 325 to the convex position, the spring rod 324 will be compressed, accumulating rebound force, pushing the scraper 321 to move laterally. As the spring rod 324 continues to move, it will contact the recessed position of the second concave-convex plate 325 again, allowing... The scraper 321 returns to its original position until the spring rod 324 contacts the protruding part of the second concave-convex plate 325 again. This process is repeated to allow the scraper 321 to move laterally back and forth, thoroughly scraping away the deposits on the top of the heat-conducting plate 213. This effectively prevents the salt spray present in the humid air of coastal areas from being impacted by humid air for a long time, causing the surface of the heat-conducting plate 213 to be affected by the salt spray, forming an adhesion layer that affects the heat transfer of the heat-conducting plate 213 and the heat dissipation effect of the airflow on the heat-conducting plate 213.

[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 the present invention is used, if it is necessary to cool the terminal 121, the electric telescopic rod 215 is activated to extend, pushing the extrusion plate 221 upward. The extrusion plate 221 extrudes the gas inside the pressure frame 214. At this time, the extruded gas is blocked by the baffle plate 222, so the gas pressure will increase. As the extrusion plate 221 continues to move, the gas pressure will gradually increase. The high-pressure gas inside the pressure frame 214 will then push the baffle plate 222 to move, causing the baffle plate 222 to separate from the pressure frame 214, extruding the spring return rod 224. This allows the spring return rod 224 to accumulate rebound force. After the baffle plate 222 separates from the pressure frame 214, it will release the obstruction of the gas, and the high-pressure gas will be sprayed out onto the terminal 121, causing the heat on the surface of the terminal 121 to be quickly transferred to the heat-conducting plate with the gas. The air flows in direction 213, allowing heat to be absorbed by the heat-conducting plate 213. At this time, the fan 122 is activated to draw in external humid air, which flows within the guide frame 211, causing the airflow to flow on the surface of the concave-convex plate 212. Since the concave-convex plate 212 is wavy, it will disturb the airflow, forcing the airflow to generate local turbulence and causing the airflow to flow irregularly. This allows the airflow to fully contact the surface of the heat-conducting plate 213, carrying away the heat from the surface of the heat-conducting plate 213 and cooling the heat-conducting plate 213. By absorbing the heat generated by the terminal 121 through the heat-conducting plate 213, and cooperating with the fan 122 to cool the heat-conducting plate 213, the direct contact between the external humid air and the terminal 121 is reduced, keeping the terminal 121 dry and effectively preventing the terminal 121 from being corroded by the contact between the humid air and the terminal 121, which would affect the transmission effect of the terminal 121. When the gas is discharged, the electric telescopic rod 215 is retracted, causing the extrusion plate 221 to descend. As the gas is discharged, the gas driving force disappears, and the blocking plate 222 will return to its original position under the influence of the spring return rod 224, blocking the gas again until the extrusion plate 221 returns to its original position, allowing the connecting hole 216 to connect with the top of the extrusion plate 221 again. The gas will then enter the top of the extrusion plate 221 through the connecting hole 216, thus replenishing the gas supply. Secondly, when the extrusion plate 221 rises, it drives the lifting rod 225 to rise, causing the lifting rod 225 to push the rocker arm 226 to rotate. This causes the side of the rocker arm 226 in contact with the lifting rod 225 to rise, while the other side falls. The falling side pushes the first concave-convex plate 212 down, compressing the second spring return rod 227, allowing it to accumulate restoring force. This brings the first concave-convex plate 212 closer to the heat-conducting plate 213, reducing the distance between them. When the distance between them decreases, the airflow velocity increases as the gas flows through the narrow section. At this time, the airflow generated by the fan 122 increases in velocity as it passes between the heat-conducting plate 213 and the first concave-convex plate 212. When the extrusion plate 221 returns to its original position, the restoring force of the second spring return rod 227 is released, causing the first concave-convex plate 212 to rise. The space between the concave-convex plate 212 and the heat-conducting plate 213 is increased again, and the airflow speed is slowed down until the lifting rod 225 pushes the rocker 226 to rotate again, causing the concave-convex plate 212 to descend. This process is repeated, which intermittently increases the airflow speed. The increased airflow speed will destroy the thermal boundary layer of the heat-conducting plate 213, making it easier for heat to be transferred. When the flow speed slows down, the thermal boundary layer gradually forms again. This repeated action, compared with a constant flow speed, will enhance the heat exchange of the heat-conducting plate 213, improve the cooling efficiency of the heat-conducting plate 213, and effectively prevent the high-pressure gas in the air pressure frame 214 from carrying away the heat on the surface of the terminal 121, which would cause the heat-conducting plate 213 to absorb too much heat, making it difficult for the airflow to quickly reduce the heat of the heat-conducting plate 213 and causing the heat to accumulate in the heat-conducting plate 213. Secondly, to address the issue of condensation that may occur at the bottom of the heat-conducting plate 213 during the cooling process, causing water droplets to fall onto the surface of the terminal 121, the connecting rod 312 descends as the concave-convex plate 212 descends. This causes the connecting rod 312 to push the connecting rod 314 to rotate, which in turn pushes the push frame 313 to move, thus moving the U-shaped frame 315. This causes the U-shaped frame 315 to contact the bottom of the heat-conducting plate 213, scraping away the condensed water droplets. The water droplets fall into the U-shaped frame 315, where they gather together and are finally drained through the drain pipe 316. This effectively prevents water droplets from condensing at the bottom of the heat-conducting plate 213 during the cooling process, thus preventing the terminal 121 from becoming damp. Secondly, when the pusher 313 moves, it drives the pusher 322 to move, causing the pusher 322 to push the scraper 321 to move, which in turn drives the sliding sleeve 323 and the spring rod 324 to move. When the spring rod 324 moves from the recessed position of the second concave-convex plate 325 to the convex position, the spring rod 324 will be compressed, accumulating rebound force, pushing the scraper 321 to move laterally. As the spring rod 324 continues to move, it will contact the recessed position of the second concave-convex plate 325 again, allowing... The scraper 321 returns to its original position until the spring rod 324 contacts the protruding part of the second concave-convex plate 325 again. This process is repeated to allow the scraper 321 to move laterally back and forth, thoroughly scraping away the deposits on the top of the heat-conducting plate 213. This effectively prevents the salt spray present in the humid air of coastal areas from being impacted by humid air for a long time, causing the surface of the heat-conducting plate 213 to be affected by the salt spray, forming an adhesion layer that affects the heat transfer of the heat-conducting plate 213 and the heat dissipation effect of the airflow on the heat-conducting plate 213.
