Description

Technical Field

[0001] This invention relates to the field of charging pile technology, specifically to a new energy vehicle charging pile with a heat dissipation structure. Background Technology

[0002] With the continuous development of society, the popularization of new energy vehicles is an inevitable trend. New energy vehicles are powered by batteries, so the popularization of charging piles is carried out simultaneously, and the quality requirements for charging piles are constantly increasing.

[0003] Patent publication number CN220518005U discloses a new energy vehicle charging pile with a multi-level heat dissipation structure, including a housing; multiple sets of circular grooves are respectively opened on both sides of the housing; a first rotating plate is fixedly connected to one end of the circular groove, and a second rotating plate is rotatably connected to the other end of the circular groove; multiple sets of heat dissipation holes are correspondingly and equidistantly arranged around the first and second rotating plates, and a dustproof mesh is fixedly connected inside the heat dissipation holes; a connecting rod is fixedly connected to one edge of the first rotating plate; an arc-shaped sliding groove is opened at the inner edge of the second rotating plate, and the connecting rod is located inside the arc-shaped sliding groove; this patent allows the second rotating plate to be rotated and adjusted so that it blocks the heat dissipation holes opened inside the first rotating plate, thereby reducing the risk of rainwater flowing into the charging pile housing through the heat dissipation holes and damaging the internal components of the charging pile during continuous rainy weather.

[0004] However, the device still has shortcomings: the device uses a rotating plate to prevent rainwater from flowing into the housing through the heat dissipation holes, but when the charging pile is put into use in the rain, if the heat dissipation holes are closed, it is easy for the heat inside to be difficult to dissipate quickly. When too much heat accumulates inside the charging pile, it is easy to trigger the overheat protection, thereby reducing the charging efficiency and making it difficult to ensure the effectiveness of the equipment. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a new energy vehicle charging pile with a heat dissipation structure, thus solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a new energy vehicle charging pile with a heat dissipation structure, comprising a charging mechanism, wherein an electric push rod is fixedly installed at each of the top corners of the charging mechanism, the electric push rod being telescopic, a protective plate is fixedly installed at the top of the telescopic end of the electric push rod, the edge of the protective plate being arc-shaped, a water storage box is fixedly installed inside one end of the back of the protective plate, a plurality of L-shaped heat dissipation pipes are fixedly installed at equal intervals at the bottom of the water storage box, a vertical rod is fixedly installed at the bottom edge of the protective plate, a horizontal plate is fixedly installed at the bottom of the vertical rod, a negative pressure mechanism is fixedly installed at the bottom of the horizontal plate, an anti-corrosion device is provided below the negative pressure mechanism to ensure that the inside of the charging mechanism remains dry during rainy days, and a short-circuit prevention device is provided around the anti-corrosion device to remove moisture from the inside of the charging mechanism.

[0007] According to the above technical solution, the charging mechanism has a heat dissipation groove inside, a mounting base is provided at the bottom of the charging mechanism, and a charging gun mechanism is provided on the left side of the charging mechanism. The charging gun mechanism is used to connect the charging mechanism to the new energy vehicle for charging. A protective mesh plate is fixedly installed inside the heat dissipation groove of the charging mechanism. The protective mesh plate ensures heat dissipation of the charging mechanism while preventing external dirt from entering its interior. A round rod is fixedly installed on the outer wall of the protective mesh plate, and a baffle is rotatably installed on the outer wall of the round rod. The baffle can block the heat dissipation holes of the protective mesh plate.

[0008] According to the above technical solution, the water storage box collects rainwater flowing from the top of the protective plate. The top of the L-shaped heat dissipation pipe is connected to the inside of the water storage box, and the outer wall of the L-shaped heat dissipation pipe contacts the back of the charging mechanism. The L-shaped heat dissipation pipe carries away the heat generated by the charging mechanism during operation through rainwater. The bottom end of the vertical rod moves through the inside of the charging mechanism, and the negative pressure mechanism conducts the heat inside the charging mechanism to its back. When a rainstorm occurs, the charging mechanism located in the factory area can rotate a baffle along the outer wall of the round rod. After the baffle rotates, it blocks the slots inside the protective mesh plate, thus sealing the heat dissipation slots of the charging mechanism and preventing external rainwater from entering the charging mechanism. When the charging mechanism is in a sealed state, the electric push rod is activated, and the electric... The push rod extends and retracts, causing the protective plate to move upward and reset. This process repeats, causing the water tank to move upward and reset repeatedly. This causes rainwater on the top of the protective plate to flow into the water tank through its curved edge. The rainwater inside the water tank flows into the L-shaped heat dissipation pipe. As the L-shaped heat dissipation pipe moves upward and reset through the water tank, it continuously contacts the heat source on the back of the charging mechanism. The protective plate moves the vertical rod upward and resets, which in turn moves the horizontal plate. Simultaneously, the horizontal plate causes the negative pressure mechanism to move upward and reset within the charging mechanism. Once activated, the negative pressure mechanism draws the heat generated inside the charging mechanism towards its back, where it is then carried away by the rainwater flowing through the L-shaped heat dissipation pipe.

[0009] According to the above technical solution, the anti-corrosion device includes an L-shaped plate. The top of the L-shaped plate is fixedly installed at the bottom of the negative pressure mechanism. A drying box is fixedly installed at the bottom of the inner wall of the charging mechanism. The drying box contains desiccant particles. A venting groove is opened at the top of the drying box. A rotating rod is rotatably installed at the center of the bottom of the inner wall of the drying box. Several interference plates are fixedly installed at equal intervals on the outer wall of the bottom end of the rotating rod. A trapezoidal scraper is fixedly installed on the outer wall of the interference plates.

[0010] According to the above technical solution, a non-self-locking spiral groove is provided on the outer wall of the top of the rotating rod. The outer wall of the spiral groove of the rotating rod is penetrated and movably installed inside the bottom of the L-shaped plate. The bottom of the material-dispersing plate is in contact with the bottom of the inner wall of the drying chamber. The material-dispersing plate is used to ensure the looseness of the desiccant particles. The trapezoidal scraper scrapes the desiccant particles adhering to the bottom of the inner wall of the drying chamber. The negative pressure mechanism drives the L-shaped plate to move upward and reset. When the L-shaped plate moves upward along the outer wall of the non-self-locking spiral groove of the rotating rod, the limiting of the spiral groove causes the rotating rod to generate a rotational force. When the rotating rod rotates, it drives the material-dispersing plate to revolve inside the drying chamber. The material-dispersing plate drives the trapezoidal scraper to revolve. Thus, the material-dispersing plate revolve and guides the desiccant particles inside the drying chamber, and the trapezoidal scraper revolve and scrapes the bottom of the inner wall of the drying chamber.

[0011] According to the above technical solution, two irregularly shaped plates are symmetrically and fixedly installed on the outer wall of the bottom end of the L-shaped plate. A heat-conducting plate is fixedly installed on the top of the irregularly shaped plate. The heat-conducting plate is used to expand the heat distribution range inside the charging mechanism. The L-shaped plate drives the irregularly shaped plate to move upward and reset. The irregularly shaped plate drives the heat-conducting plate to move synchronously. The heat-conducting plate expands the distribution range of the heat absorbed by the negative pressure mechanism in the back direction of the charging mechanism.

[0012] According to the above technical solution, the anti-short circuit device includes several friction wheels, which are symmetrically and rotatably installed inside the end of the irregular plate away from the L-shaped plate. A reciprocating screw is fixedly installed on one side of the friction wheels, which are close to each other. A transmission plate is movably installed through the outer wall of the reciprocating screw, and a humidity detector is fixedly installed inside the transmission plate.

[0013] According to the above technical solution, the outer wall of the friction wheel contacts the inner wall of the charging mechanism, the outer wall of the reciprocating screw is a non-self-locking reciprocating spiral groove, the outer wall of the transmission plate is slidably installed on the surface of the irregular plate, and the humidity detector is used to monitor the humidity inside the charging mechanism in rainy weather. The irregular plate drives the friction wheel to move upward along the inner wall of the charging mechanism and reset. The friction wheel generates friction with the inner wall of the charging mechanism and rotates inside the irregular plate. When the friction wheel rotates, it drives the reciprocating screw to rotate. When the reciprocating screw rotates, it is restricted by the non-self-locking reciprocating spiral groove on its outer wall, driving the transmission plate to move horizontally reciprocally along the surface of the irregular plate. The transmission plate drives the humidity detector to move synchronously, so that the humidity detector moves horizontally while moving upward.

[0014] According to the above technical solution, an elastic loop frame is fixedly installed on the top of the transmission plate. The elastic loop frame is telescopic, and an absorbent cotton block is fixedly installed inside the elastic loop frame. The absorbent cotton block contacts the inner wall of the charging mechanism and wipes and absorbs the moisture adhering to the inner wall of the charging mechanism. An abutment block is fixedly installed on the inner wall of the charging mechanism. The abutment block is located on the horizontal movement trajectory of the telescopic end of the elastic loop frame. The transmission plate drives the elastic loop frame to move synchronously. When the elastic loop frame drives the absorbent cotton block to move synchronously, the absorbent cotton block continuously wipes the inner wall of the charging mechanism. During the movement, the telescopic end of the elastic loop frame contacts the abutment block. The limiting action of the abutment block causes the telescopic end of the elastic loop frame to begin to contract. At this time, the telescopic end of the elastic loop frame squeezes and deforms the absorbent cotton block. Afterward, when the elastic loop frame returns to its original position by the spring force, it causes the absorbent cotton block to return to its original position synchronously. This process is repeated.

[0015] This invention provides a new energy vehicle charging pile with a heat dissipation structure. It has the following beneficial effects: (1) The present invention uses an electric push rod, a protective plate, a water storage box, an L-shaped heat dissipation pipe, a vertical rod, a horizontal plate and a negative pressure mechanism to work together. The extension and retraction of the electric push rod effectively prevents rainwater from accumulating on the top of the protective plate, and the protective plate reduces the erosion of the top of the charging mechanism by rainwater. At the same time, when the L-shaped heat dissipation pipe moves back and forth, it carries away the heat of the heat source on the back of the charging mechanism through the rainwater flowing inside, thereby preventing the charging mechanism from overheating in the sealed state and ensuring the charging effect. The reciprocating negative pressure mechanism concentrates the heat inside the charging mechanism, improves the heat dissipation rate on the original basis, and ensures that the charging mechanism always maintains the best working state.

[0016] (2) The present invention, through the setting of the anti-corrosion device, through the cooperation of negative pressure mechanism, L-shaped plate, drying box, rotating rod, material scraper, trapezoidal scraper, irregular plate and heat conduction plate, ensures that the desiccant particles remain loose in the sealed state of the charging mechanism by the revolution of the material scraper, so that the desiccant particles can uniformly volatilize the drying gas to ensure the dryness inside the charging mechanism. At the same time, the trapezoidal scraper effectively prevents the desiccant particles from oxidizing when left to stand for a long time, and avoids them from adhering to the inside of the drying box, thus increasing the difficulty of subsequent replacement. The heat conduction plate and L-shaped heat dissipation pipe reciprocate at the same frequency to disperse the relatively concentrated heat, so that the overall temperature of the back of the charging mechanism is relatively uniform, avoiding the formation of temperature difference due to local high temperature on the back of the charging mechanism, preventing the back of the charging mechanism from deforming due to temperature difference during long-term use, and extending its maintenance cycle.

[0017] (3) By setting up a short-circuit protection device, the present invention uses a combination of a shaped plate, a friction wheel, a reciprocating screw, a transmission plate, a humidity detector, an elastic loop frame, a water-absorbing cotton block, and a contact block to expand the detection range of the humidity detector and improve the accuracy of the humidity detector in detecting the humidity inside the charging mechanism. This allows staff to know at all times whether the charging mechanism is corroded by moisture in a rainstorm and sealed state, so as to take timely maintenance measures and effectively avoid short circuits caused by excessive moisture in the charging mechanism. The water-absorbing cotton block absorbs the water vapor generated by the temperature difference between the inside and outside of the charging mechanism, preventing water vapor from adhering to the inner wall of the charging mechanism and causing corrosion. The reciprocating deformation of the water-absorbing cotton block distributes the water vapor evenly inside itself to prevent it from overflowing. Then, the drying gas emitted by the drying box achieves rapid drying treatment, so that the water-absorbing cotton block is always kept dry for use. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Please see Figures 1-8 One embodiment of the present invention is as follows: a new energy vehicle charging pile with a heat dissipation structure, including a charging mechanism 1, an electric push rod 7 is fixedly installed at the top corner of the charging mechanism 1, the electric push rod 7 is telescopic, a protective plate 8 is fixedly installed at the top of the telescopic end of the electric push rod 7, the edge of the protective plate 8 is arc-shaped, a water storage box 9 is fixedly installed inside one end of the back of the protective plate 8, a plurality of L-shaped heat dissipation pipes 10 are fixedly installed at equal intervals at the bottom of the water storage box 9, a vertical rod 11 is fixedly installed at the bottom edge of the protective plate 8, a horizontal plate 12 is fixedly installed at the bottom of the vertical rod 11, a negative pressure mechanism 13 is fixedly installed at the bottom of the horizontal plate 12, an anti-corrosion device 14 is provided below the negative pressure mechanism 13 to ensure that the inside of the charging mechanism 1 remains dry in rainy weather, and a short-circuit prevention device 15 is provided around the anti-corrosion device 14 to remove moisture from the inside of the charging mechanism 1.

[0022] The charging mechanism 1 has a heat dissipation slot inside, and a mounting base 2 is provided at the bottom of the charging mechanism 1. A charging gun mechanism 3 is provided on the left side of the charging mechanism 1. The charging gun mechanism 3 is used to connect the charging mechanism 1 to the new energy vehicle for charging. A protective mesh plate 4 is fixedly installed inside the heat dissipation slot of the charging mechanism 1. The protective mesh plate 4 ensures the heat dissipation of the charging mechanism 1 while preventing external dirt from entering its interior. A round rod 5 is fixedly installed on the outer wall of the protective mesh plate 4. A baffle 6 is rotatably installed on the outer wall of the round rod 5. The baffle 6 can block the heat dissipation holes of the protective mesh plate 4.

[0023] The water storage box 9 collects the rainwater flowing from the top of the protective plate 8. The top of the L-shaped heat dissipation pipe 10 is connected to the inside of the water storage box 9. The outer wall of the L-shaped heat dissipation pipe 10 is in contact with the back of the charging mechanism 1. The L-shaped heat dissipation pipe 10 carries away the heat generated by the charging mechanism 1 during operation through the rainwater. The bottom end of the vertical rod 11 moves through the inside of the charging mechanism 1. The negative pressure mechanism 13 conducts the heat inside the charging mechanism 1 to its back.

[0024] The extension and retraction of the electric push rod 7 effectively prevents rainwater from accumulating on the top of the protective plate 8, and the protective plate 8 reduces the corrosion of the top of the charging mechanism 1 by rainwater. At the same time, when the L-shaped heat dissipation pipe 10 reciprocates, it carries away the heat from the heat source on the back of the charging mechanism 1 through the rainwater flowing inside, thereby preventing the charging mechanism 1 from overheating in the sealed state and ensuring the charging effect. The reciprocating negative pressure mechanism 13 concentrates the heat inside the charging mechanism 1, improving the heat dissipation rate on the original basis and ensuring that the charging mechanism 1 always maintains the optimal working state.

[0025] In use, when heavy rain occurs, the charging mechanism 1 located in the factory area can rotate the baffle 6 along the outer wall of the round rod 5. After the baffle 6 rotates, it blocks the slot inside the protective mesh plate 4, thus sealing the heat dissipation groove of the charging mechanism 1 and preventing external rainwater from entering the charging mechanism 1. When the charging mechanism 1 is in a sealed state, the electric push rod 7 is activated. The telescopic end of the electric push rod 7 drives the protective plate 8 to move upward and then reset. This process is repeated, and the protective plate 8 drives the water storage box 9 to move upward and reset repeatedly, causing the rainwater on the top of the protective plate 8 to flow into the water storage box 9 through its edge arc. Rainwater will flow into the L-shaped heat dissipation pipe 10, and as the L-shaped heat dissipation pipe 10 moves back and forth and resets through the water storage box 9, it continuously contacts the heat source on the back of the charging mechanism 1. The protective plate 8 drives the vertical rod 11 to move upward and reset, and the vertical rod 11 drives the horizontal plate 12 to move synchronously. At the same time, the horizontal plate 12 drives the negative pressure mechanism 13 to move back and forth and reset inside the charging mechanism 1. After the negative pressure mechanism 13 is activated, it draws the heat generated inside the charging mechanism 1 towards its back, and then the rainwater flowing inside the L-shaped heat dissipation pipe 10 carries away the heat.

[0026] According to the above embodiments, the extension and retraction of the electric push rod 7 effectively prevents rainwater from accumulating on the top of the protective plate 8, and the protective plate 8 reduces the erosion of the top of the charging mechanism 1 by rainwater. At the same time, when the L-shaped heat dissipation pipe 10 reciprocates, it carries away the heat from the heat source on the back of the charging mechanism 1 through the rainwater flowing inside, thereby preventing the charging mechanism 1 from overheating in the sealed state and ensuring the charging effect. The reciprocating negative pressure mechanism 13 concentrates the heat inside the charging mechanism 1, improves the heat dissipation rate on the original basis, and ensures that the charging mechanism 1 is always maintained in the best working state.

[0027] Please see Figures 1-8 Based on the above embodiments, another embodiment of the present invention further includes an anti-corrosion device 14; The anti-corrosion device 14 includes an L-shaped plate 141. The top of the L-shaped plate 141 is fixedly installed at the bottom of the negative pressure mechanism 13. A drying box 142 is fixedly installed at the bottom of the inner wall of the charging mechanism 1. The drying box 142 contains desiccant granules. A ventilation groove is opened at the top of the drying box 142. A rotating rod 143 is rotatably installed at the center of the bottom of the inner wall of the drying box 142. A few interfering material plates 144 are fixedly installed at equal intervals on the outer wall of the bottom end of the rotating rod 143. A trapezoidal scraper 145 is fixedly installed on the outer wall of the interfering material plates 144.

[0028] The top outer wall of the rotating rod 143 is provided with a non-self-locking spiral groove. The spiral groove of the rotating rod 143 is penetrated through the outer wall and movably installed inside the bottom of the L-shaped plate 141. The bottom of the material shovel 144 is in contact with the bottom of the inner wall of the drying box 142. The material shovel 144 is used to ensure the looseness of the desiccant particles. The trapezoidal scraper 145 scrapes the desiccant particles adhering to the bottom of the inner wall of the drying box 142.

[0029] Two irregularly shaped plates 146 are symmetrically and fixedly installed on the outer wall of the bottom end of the L-shaped plate 141. A heat-conducting plate 147 is fixedly installed on the top of the irregularly shaped plate 146. The heat-conducting plate 147 is used to expand the heat distribution range inside the charging mechanism 1.

[0030] The rotating baffle plate 144 ensures that the desiccant particles remain loose even when the charging mechanism 1 is sealed, allowing the desiccant particles to evenly release drying gas and thus ensuring the dryness inside the charging mechanism 1. At the same time, the trapezoidal scraper 145 effectively prevents the desiccant particles from oxidizing when left to stand for a long time, avoiding their adhesion to the inside of the drying box 142 and thus increasing the difficulty of subsequent replacement. The heat-conducting plate 147 and the L-shaped heat dissipation pipe 10 reciprocate at the same frequency, dispersing the relatively concentrated heat and making the overall temperature of the back of the charging mechanism 1 more uniform. This prevents the back of the charging mechanism 1 from forming temperature differences due to local overheating, thus preventing deformation of the back of the charging mechanism 1 due to temperature differences during long-term use and extending its maintenance cycle.

[0031] In use, the negative pressure mechanism 13 drives the L-shaped plate 141 to move upward and reset. When the L-shaped plate 141 moves upward along the outer wall of the non-self-locking spiral groove of the rotating rod 143, the limiting of the spiral groove causes the rotating rod 143 to generate a rotational force. When the rotating rod 143 rotates, it drives the material-scraping plate 144 to revolve inside the drying chamber 142. The material-scraping plate 144 drives the trapezoidal scraper 145 to revolve. Thus, the material-scraping plate 144 revolves and guides the desiccant particles inside the drying chamber 142, and the trapezoidal scraper 145 revolves and scrapes the bottom of the inner wall of the drying chamber 142. The L-shaped plate 141 drives the irregular plate 146 to move upward and reset. The irregular plate 146 drives the heat-conducting plate 147 to move synchronously. The heat-conducting plate 147 expands the distribution range of the heat absorbed by the negative pressure mechanism 13 in the back direction of the charging mechanism 1.

[0032] According to the above embodiments, the rotation of the desiccant plate 144 ensures that the desiccant particles remain loose in the sealed state of the charging mechanism 1, promoting the uniform evaporation of drying gas from the desiccant particles to ensure the dryness inside the charging mechanism 1. At the same time, the trapezoidal scraper 145 effectively prevents the desiccant particles from oxidizing when left to stand for a long time, avoiding their adhesion to the inside of the drying box 142 and thus increasing the difficulty of subsequent replacement. The heat-conducting plate 147 and the L-shaped heat dissipation pipe 10 reciprocate at the same frequency, dispersing the relatively concentrated heat, so that the overall temperature of the back of the charging mechanism 1 is more uniform, avoiding the formation of temperature differences due to excessive local temperature on the back of the charging mechanism 1, and preventing deformation of the back of the charging mechanism 1 due to temperature differences during long-term use, thus extending its maintenance cycle.

[0033] Please see Figures 1-8 Based on the above embodiments, another embodiment of the present invention further includes a short-circuit protection device 15; The short-circuit protection device 15 includes several friction wheels 151, which are symmetrically and rotatably installed inside the end of the irregular plate 146 away from the L-shaped plate 141. A reciprocating screw 152 is fixedly installed on one side of the several friction wheels 151 close to each other. A transmission plate 153 is movably installed through the outer wall of the reciprocating screw 152. A humidity detector 154 is fixedly installed inside the transmission plate 153.

[0034] The outer wall of the friction wheel 151 contacts the inner wall of the charging mechanism 1. The outer wall of the reciprocating screw 152 is a non-self-locking reciprocating spiral groove. The outer wall of the transmission plate 153 is slidably mounted on the surface of the irregular plate 146. The humidity detector 154 is used to monitor the humidity inside the charging mechanism 1 in rainy weather.

[0035] An elastic loop frame 155 is fixedly installed on the top of the transmission plate 153. The elastic loop frame 155 is telescopic. An absorbent cotton block 156 is fixedly installed inside the elastic loop frame 155. The absorbent cotton block 156 contacts the inner wall of the charging mechanism 1 and wipes and absorbs the water vapor adhering to the inner wall of the charging mechanism 1. An abutment block 157 is fixedly installed on the inner wall of the charging mechanism 1. The abutment block 157 is located on the horizontal movement trajectory of the telescopic end of the elastic loop frame 155.

[0036] By expanding the detection range of the humidity detector 154, the accuracy of the humidity detector 154 in detecting the internal humidity of the charging mechanism 1 is improved. This allows staff to be aware of whether the charging mechanism 1 is corroded by moisture in heavy rain and under sealed conditions, and to take timely maintenance measures to effectively prevent short circuits caused by excessive moisture in the charging mechanism 1. The absorbent cotton block 156 absorbs the moisture generated by the temperature difference between the inside and outside of the charging mechanism 1, preventing moisture from adhering to the inner wall of the charging mechanism 1 and causing corrosion. The reciprocating deformation of the absorbent cotton block 156 evenly distributes the moisture inside itself to prevent it from overflowing. Then, the dry gas emitted by the drying box 142 achieves rapid drying, keeping the absorbent cotton block 156 in a dry state for use.

[0037] In use, the irregular plate 146 drives the friction wheel 151 to move upward along the inner wall of the charging mechanism 1 and then reset. The friction wheel 151 generates friction with the inner wall of the charging mechanism 1 and rotates inside the irregular plate 146. When the friction wheel 151 rotates, it drives the reciprocating screw 152 to rotate. When the reciprocating screw 152 rotates, it is restricted by the non-self-locking reciprocating spiral groove on its outer wall, which drives the transmission plate 153 to reciprocate horizontally along the surface of the irregular plate 146. The transmission plate 153 drives the humidity detector 154 to move synchronously. Thus, the humidity detector 154 moves horizontally while moving upward. The transmission plate 153 drives the elastic loop frame 155 to move synchronously. When the elastic loop frame 155 drives the absorbent cotton block 156 to move synchronously, the absorbent cotton block 156 continuously wipes the inner wall of the charging mechanism 1. During the movement, the telescopic end of the elastic loop frame 155 contacts the abutment block 157. The limiting of the abutment block 157 causes the telescopic end of the elastic loop frame 155 to begin to contract. At this time, the telescopic end of the elastic loop frame 155 squeezes and deforms the absorbent cotton block 156. Afterwards, when the elastic loop frame 155 resets due to the spring force, it causes the absorbent cotton block 156 to reset synchronously. This process is repeated.

[0038] According to the above embodiments, by expanding the detection range of the humidity detector 154, the accuracy of the humidity detector 154 in detecting the internal humidity of the charging mechanism 1 is improved. This allows staff to know at all times whether the charging mechanism 1 is corroded by moisture in a rainstorm and sealed state, so as to take timely maintenance measures and effectively avoid short circuits caused by excessive moisture in the charging mechanism 1. The absorbent cotton block 156 absorbs the water vapor generated by the temperature difference between the inside and outside of the charging mechanism 1, preventing water vapor from adhering to the inner wall of the charging mechanism 1 and causing corrosion. The reciprocating deformation of the absorbent cotton block 156 evenly distributes the water vapor inside itself to prevent it from overflowing. Then, the drying gas emitted by the drying box 142 achieves rapid drying treatment, so that the absorbent cotton block 156 is always kept dry for use.
