Description

Technical Field

[0001] This invention relates to the field of charging pile technology, specifically to a new energy charging pile with self-protection function. Background Technology

[0002] With the rapid development of the global new energy vehicle industry, the number of charging piles is also increasing. Charging pile technology will develop towards higher power, intelligence, and convenience. On the one hand, high-power fast charging technology will continue to mature and become more widespread, shortening charging time.

[0003] Patent CN214492576U discloses a charging pile with heat dissipation and anti-theft functions, comprising a charging pile body and a base; the base has vents arranged in a rectangular array on both the front and rear sides, a wireless transceiver module is fixed inside the lower side of the base, and grounding screws are threaded through the left and right ends of the base; the charging pile body is inserted into the upper end of the base at its lower end, has vents on both the front and rear sides of its upper end, and has vents arranged in a linear array on its lower side; a fan is fixed to the lower side of the charging pile body, and the fan is located directly below the vents. The charging pile body has side shells fixed on both the left and right sides. This device is a charging pile with heat dissipation and anti-theft functions. First, it can ventilate the inside of the charging pile and avoid direct sunlight, thereby dissipating heat from the charging pile. It can also hold the ground anchor after the charging pile is installed to prevent the anchor from being pulled out, thus preventing the charging pile from being stolen. However, when this device is impacted, the charging pile may collapse and be damaged due to the large impact force, which may also cause the charging pile to catch fire. Therefore, a new energy charging pile with self-protection function is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a new energy charging pile with self-protection function in view of the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a new energy charging pile with self-protection function, including a charging pile body, a cabinet door rotatably connected to the inner wall of the charging pile body, a ventilation window fixedly connected to the inner wall of the charging pile body, an elastic telescopic column fixedly connected to the front of the charging pile body, a buffer plate fixedly connected to the circumferential surface of the telescopic end of the elastic telescopic column, a straight plate fixedly connected to the inner wall of the buffer plate, a support frame fixedly connected to the inner wall of the charging pile body, a sloping plate fixedly connected to the top of the straight plate, a T-shaped sloping plate slidably connected to the inner wall of the support frame, a clamping plate fixedly connected to the top of the T-shaped sloping plate, a motor fixedly connected to the inner wall of the charging pile body, a lead screw rotatably connected to the output end of the motor, a brush plate movably connected to the circumferential surface of the lead screw, a smoke detector installed on the inner wall of the charging pile body, a fireproof device for preventing fire on the inner wall of the charging pile body, and an oxygen isolation device on the left side of the charging pile body. The device includes an air isolation mechanism. The inner wall of the charging pile body is slidably connected to the surface of the straight plate. The bottom of the T-shaped inclined plate is in contact with the top of the inclined plate. The surface of the card plate is in contact with the inner wall of the charging pile body. The right side of the ventilation window is in contact with the left side of the brush plate. The smoke detector is electrically connected to the motor. When the charging pile is impacted, the device can reduce the impact force on the charging pile to a certain extent, thus protecting the charging pile. It can also lock the cabinet door to prevent it from rotating inward after the charging pile is impacted, which could cause a short circuit in the electronic components inside the charging pile and lead to a fire. It can also prevent unauthorized personnel from opening the charging pile, which could pose a potential safety risk. During normal use of the charging pile, the brush plate moves upward when the screw rotates clockwise, thus preventing the ventilation window from being blocked by dust and debris, which could lead to poor air circulation and cause the internal temperature of the charging pile to become too high, affecting the normal use of the charging pile.

[0006] Preferably, the fireproof device includes a dry powder box, which is fixedly connected to the inner wall of the charging pile body. A movable door is rotatably connected to the inner wall of the dry powder box. A sliding groove is fixedly connected to the bottom of the dry powder box, and an L-shaped baffle is slidably connected to the inner wall of the sliding groove. A connecting plate is fixedly connected to the right side of the brush plate, and a triangular plate is fixedly connected to the right side of the connecting plate. An angled plate is fixedly connected to the bottom of the L-shaped baffle. An A-shaped plate is fixedly connected to the top of the brush plate, and a fixing plate is fixedly connected to the bottom of the brush plate. A brush roller is rotatably connected to the inner wall of the fixing plate, and a transmission wheel is rotatably connected to the central shaft of the brush roller. The bottom of the dry powder box and the top of the L-shaped baffle are in contact with each other. The bottom of the movable door contacts the top of the L-shaped baffle, the top of the triangular plate contacts the bottom of the beveled plate, the top of the connecting plate contacts the bottom of the A-shaped plate, and the left side of the ventilation window contacts the circumferential surface of the transmission wheel. When flames or smoke from a fire appear inside the charging pile, the dry powder in the dry powder box can be sprinkled onto the fire location, thereby quickly controlling the fire and preventing it from spreading rapidly in a short time. This buys valuable time for personnel evacuation and further rescue work. At the same time, the rotation of the transmission wheel drives the brush roller to rotate, which can further improve the ventilation effect of the ventilation window and prevent the ventilation window from being blocked, causing the temperature inside the charging pile to become too high.

[0007] Preferably, the partition device includes a limiting block slidably connected to the inner wall of the charging pile body; a partition door slidably connected to the inner wall of the ventilation window; a push rod fixedly connected to the inner wall of the A-shaped plate; a fixing block fixedly connected to the left side of the dry powder box; a rotating rod rotatably connected to the inner wall of the fixing block via a torsion spring; an L-shaped plate fixedly connected to the circumferential surface of the rotating rod; a striking plate fixedly connected to the circumferential surface of the rotating rod; an inclined block fixedly connected to the top of the brush plate; and the surface of the limiting block contacting the inner wall of the partition door. The right side of the ventilation window and the left side of the inclined block come into contact with each other. During the fire extinguishing process of the charging pile, the rotating rod rotates, which drives the striking plate to rotate, thereby striking the surface of the dry powder box and generating vibration. This breaks the sealing structure of the dry powder box, allowing the dry powder extinguishing agent to be released quickly, preventing the dry powder from getting damp and clumping, which would prevent it from being released normally. At the same time, the partition door moves downward by gravity, thereby closing the ventilation window and isolating the airflow between the inside and outside of the charging pile, thereby reducing the oxygen content inside the charging pile and reducing the further expansion of the internal flames.

[0008] The present invention, by adopting the above technical solution, can bring the following beneficial effects: This new energy charging pile with self-protection function works in coordination with the charging pile body, cabinet door, ventilation window, elastic telescopic column, buffer plate, straight plate, support frame, inclined plate, T-shaped inclined plate, card plate, and smoke detector. When the charging pile is impacted, it can reduce the impact force to a certain extent, thus protecting the charging pile. At the same time, it can lock the cabinet door to prevent it from rotating inward after the charging pile is impacted, which could cause short circuits in the electronic components inside the charging pile and lead to fire. It can also prevent unauthorized personnel from opening the charging pile and causing potential safety risks.

[0009] 2. This new energy charging pile with self-protection function works in coordination between the motor, lead screw, and brush plate. During normal use of the charging pile, when the lead screw rotates clockwise, the brush plate moves upward, which can prevent the ventilation window from being blocked by dust and debris, thus avoiding poor air circulation and causing the internal temperature of the charging pile to become too high, affecting the normal use of the charging pile.

[0010] 3. This new energy charging pile with self-protection function, through the coordinated operation of the dry powder box, movable door, slide, L-shaped baffle, connecting plate, triangular plate, oblique plate, A-shaped plate, fixing plate, brush roller, and transmission wheel, can sprinkle dry powder from the dry powder box onto the fire location when flames or smoke from a fire appear inside the charging pile. This can quickly control the fire and prevent it from spreading rapidly in a short period of time, thus buying valuable time for personnel evacuation and further rescue work. At the same time, the rotation of the transmission wheel drives the brush roller to rotate, which can further improve the ventilation effect of the ventilation window and prevent the ventilation window from being blocked, causing the internal temperature of the charging pile to become too high.

[0011] 4. This new energy charging pile with self-protection function works in coordination with limit blocks, partition doors, push rods, fixing blocks, rotating rods, L-shaped plates, striking plates, and inclined blocks. During the fire extinguishing process, the rotating rod rotates, causing the striking plate to rotate, thereby striking and vibrating the surface of the dry powder box. This breaks the sealing structure of the dry powder box, allowing the dry powder extinguishing agent to be released quickly, preventing the dry powder from becoming damp and clumping, which would prevent it from being released properly. At the same time, the partition door moves downwards due to gravity, thereby closing the ventilation window and isolating the airflow between the inside and outside of the charging pile, thus reducing the oxygen content inside the charging pile and preventing the internal flames from spreading further.

[0014] 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.

[0015] Please see Figures 1-9One embodiment of the present invention is as follows: a new energy charging pile with self-protection function includes a charging pile body 1, a cabinet door 2 rotatably connected to the inner wall of the charging pile body 1, a ventilation window 3 fixedly connected to the inner wall of the charging pile body 1, an elastic telescopic column 4 fixedly connected to the front of the charging pile body 1, and a buffer plate 5 fixedly connected to the circumferential surface of the telescopic end of the elastic telescopic column 4. When the charging pile is impacted, the vehicle will generate an impact force on the buffer plate 5, causing the buffer plate 5 to move backward. The backward movement of the buffer plate 5 will be buffered by the elastic telescopic column 4, thereby reducing the impact force on the charging pile to a certain extent, and thus providing a certain degree of protection for the charging pile. The inner wall of the buffer plate 5... A straight plate 6 is fixedly connected to the charging pile body 1. A support frame 7 is fixedly connected to the inner wall of the charging pile body 1. A sloping plate 8 is fixedly connected to the top of the straight plate 6. A T-shaped sloping plate 9 is slidably connected to the inner wall of the support frame 7. A locking plate 10 is fixedly connected to the top of the T-shaped sloping plate 9. Simultaneously, the buffer plate 5 moves backward, causing the straight plate 6 to move backward. The backward movement of the straight plate 6 causes the sloping plate 8 to move backward. During the movement of the sloping plate 8, it will come into contact with the T-shaped sloping plate 9 and press the T-shaped sloping plate 9 with the sloping surface, causing the T-shaped sloping plate 9 to move upward. The upward movement of the T-shaped sloping plate 9 causes the locking plate 10 to move upward, thereby locking the cabinet door 2 to prevent the cabinet door 2 from rotating inward into the charging pile after the charging pile is impacted. This prevents short circuits in the electronic components inside the charging pile, which could lead to a fire. It also prevents unauthorized personnel from opening the charging pile, thus avoiding potential safety risks. A motor 11 is fixedly connected to the inner wall of the charging pile body 1. A lead screw 12 is rotatably connected to the output end of the motor 11. A brush plate 13 is movably connected to the circumferential surface of the lead screw 12. A smoke detector 14 is installed on the inner wall of the charging pile body 1. A fireproof device 15 is installed on the inner wall of the charging pile body 1 to prevent fires. An oxygen-isolating barrier 16 is installed on the left side of the charging pile body 1. The inner wall of the charging pile body 1 is slidably connected to the surface of the straight plate 6. The bottom of the T-shaped inclined plate 9 is connected to the top of the inclined plate 8. The parts are in contact with each other, the surface of the card plate 10 is in contact with the inner wall of the charging pile body 1, the right side of the ventilation window 3 is in contact with the left side of the brush plate 13, the smoke detector 14 is electrically connected to the motor 11, and the motor 11 will start periodically during normal use of the charging pile. When the motor 11 starts, the motor 11 rotates and drives the lead screw 12 to rotate. The rotation of the lead screw 12 will cause the slider set inside the brush plate 13 to contact the thread on the surface of the lead screw 12, so that when the lead screw 12 rotates clockwise, the brush plate 13 moves upward, thereby avoiding the ventilation window 3 from being blocked by dust and debris, which would cause poor air circulation and thus cause the internal temperature of the charging pile to be too high, affecting the normal use of the charging pile.

[0016] The fire prevention device 15 includes a dry powder box 151, which is fixedly connected to the inner wall of the charging pile body 1. A movable door 152 is rotatably connected to the inner wall of the dry powder box 151. A sliding groove 153 is fixedly connected to the bottom of the dry powder box 151, and an L-shaped baffle 154 is slidably connected to the inner wall of the sliding groove 153. A connecting plate 155 is fixedly connected to the right side of the brush plate 13, and a triangular plate 156 is fixedly connected to the right side of the connecting plate 155. When a flame or smoke from a fire occurs inside the charging pile, the smoke will be detected by the smoke detector 14, thereby extending the clockwise rotation time of the motor 11, so that the brush plate 13 will... When stopped, the brush plate 13 continues to move upwards, causing the connecting plate 155 to move. The moving connecting plate 155 then moves the triangular plate 156. During this movement, the triangular plate 156 contacts the angled plate 157, exerting pressure on it and causing the angled plate 157 to move forward. This forward movement of the angled plate 157 moves the L-shaped baffle 154 forward, releasing the limit on the movable door 152. This allows the dry powder in the dry powder box 151 to be sprinkled towards the fire, quickly controlling the fire and preventing its rapid spread. This facilitates personnel evacuation and further... To buy precious time for the rescue operation, an angled plate 157 is fixedly connected to the bottom of the L-shaped baffle 154, an A-shaped plate 158 is fixedly connected to the top of the brush plate 13, a fixing plate 159 is fixedly connected to the bottom of the brush plate 13, a brush roller 1510 is rotatably connected to the inner wall of the fixing plate 159, and a transmission wheel 1511 is rotatably connected to the central shaft of the brush roller 1510. The bottom of the dry powder box 151 is in contact with the top of the L-shaped baffle 154, the bottom of the movable door 152 is in contact with the top of the L-shaped baffle 154, the top of the triangular plate 156 is in contact with the bottom of the angled plate 157, and the top of the connecting plate 155... The bottom of the A-shaped plate 158 is in contact with the ventilation window 3, and the left side of the ventilation window 3 is in contact with the circumferential surface of the transmission wheel 1511. At the same time, the movement of the brush plate 13 drives the fixed plate 159 to move, the movement of the fixed plate 159 drives the brush roller 1510 to move, and the movement of the brush roller 1510 drives the transmission wheel 1511 to move. During the movement of the transmission wheel 1511, it will come into contact with the ventilation window 3 and generate friction, causing the transmission wheel 1511 to rotate. The rotation of the transmission wheel 1511 drives the brush roller 1510 to rotate, thereby further improving the ventilation effect of the ventilation window 3 and avoiding the situation where the temperature inside the charging pile is too high due to the blockage of the ventilation window 3.

[0017] Working principle: When the charging pile is impacted, the vehicle exerts an impact force on the buffer plate 5, causing the buffer plate 5 to move backward. The backward movement of the buffer plate 5 is buffered by the elastic telescopic column 4, thus reducing the impact force on the charging pile to a certain extent and providing some protection. Simultaneously, the backward movement of the buffer plate 5 causes the straight plate 6 to move backward, which in turn causes the inclined plate 8 to move backward. During this movement, the inclined plate 8 comes into contact with the T-shaped inclined plate 9, and the inclined surface presses against the T-shaped inclined plate 9, causing it to move upward. The upward movement of the T-shaped inclined plate 9 causes the locking plate 10 to move upward, thereby locking the cabinet door 2 to prevent damage after the charging pile is impacted. The cabinet door 2 rotates inwards towards the charging pile, which can cause a short circuit in the electronic components inside the charging pile, potentially leading to a fire. It also prevents unauthorized personnel from opening the charging pile, thus avoiding potential safety risks. During normal use of the charging pile, the motor 11 will start periodically. When the motor 11 starts, it rotates, driving the lead screw 12 to rotate. The rotation of the lead screw 12 causes the slider inside the brush plate 13 to contact the thread on the surface of the lead screw 12. This causes the brush plate 13 to move upwards when the lead screw 12 rotates clockwise, thus preventing the ventilation window 3 from being blocked by dust and debris, which could lead to poor air circulation and cause the internal temperature of the charging pile to become too high, affecting the normal use of the charging pile.

[0018] When a flame or smoke from a fire appears inside the charging pile, the smoke detector 14 will detect it, thus extending the clockwise rotation time of the motor 11. This causes the brush plate 13 to continue moving upwards from its original stop position, which in turn causes the connecting plate 155 to move. The moving connecting plate 155 then moves the triangular plate 156. During this movement, the triangular plate 156 comes into contact with the angled plate 157 and exerts pressure on it, causing the angled plate 157 to move forward. The forward movement of the angled plate 157 causes the L-shaped baffle 154 to move forward, thereby releasing the limit of the movable door 152 and allowing the dry powder in the dry powder box 151 to be discharged. Spraying water onto the location of the fire can quickly control the fire and prevent it from spreading rapidly in a short period of time, thus buying valuable time for personnel evacuation and further rescue work. At the same time, the movement of the brush plate 13 drives the movement of the fixed plate 159, which in turn drives the movement of the brush roller 1510. The movement of the brush roller 1510 drives the movement of the transmission wheel 1511. During the movement of the transmission wheel 1511, it will come into contact with the ventilation window 3 and generate friction, causing the transmission wheel 1511 to rotate. The rotation of the transmission wheel 1511 drives the rotation of the brush roller 1510, thereby further improving the ventilation effect of the ventilation window 3 and preventing the ventilation window 3 from being blocked, which could cause the temperature inside the charging pile to become too high.

[0019] Please see Figures 1-9Based on the above embodiments, in another embodiment of the present invention, the partition device 16 includes a limiting block 161, which is slidably connected to the inner wall of the charging pile body 1. A partition door 162 is slidably connected to the inner wall of the ventilation window 3. A push rod 163 is fixedly connected to the inner wall of the A-shaped plate 158. A fixing block 164 is fixedly connected to the left side of the dry powder box 151. A rotating rod 165 is rotatably connected to the inner wall of the fixing block 164 via a torsion spring. During the fire extinguishing process of the charging pile, the A-shaped plate 158... The movement of the push rod 163 causes it to move, which in turn contacts the L-shaped plate 166 and exerts an upward pushing force on it, causing the L-shaped plate 166 to rotate clockwise. This rotation of the L-shaped plate 166 then rotates the rotating rod 165, which in turn rotates the striking plate 167. This causes the plate to strike and vibrate the surface of the dry powder box 151, breaking its sealing structure and allowing the dry powder extinguishing agent to be released rapidly, preventing the dry powder from becoming damp and clumping. This prevents normal release. An L-shaped plate 166 is fixedly connected to the circumferential surface of the rotating rod 165, and a striking plate 167 is also fixedly connected to the circumferential surface of the rotating rod 165. A wedge block 168 is fixedly connected to the top of the brush plate 13. The surface of the limiting block 161 is in contact with the inner wall of the partition door 162, and the right side of the ventilation window 3 is in contact with the left side of the wedge block 168. Simultaneously, the brush plate 13 moves upward, causing the wedge block 168 to move upward. During this movement, the wedge block 168 will come into contact with the limiting block 161. The limiting block 161 is subjected to a squeezing force, causing it to move to the left. As it moves, the limiting block 161 comes into contact with the partition door 162. After moving a certain distance, the partition door 162 slides out through the inner wall of the limiting block 161, releasing the limiting effect on the partition door 162. This allows the partition door 162 to move downwards by gravity, thereby closing the ventilation window 3 and isolating the airflow between the inside and outside of the charging pile. This reduces the oxygen content inside the charging pile, thus reducing the risk of further expansion of the internal flame.

[0020] Working principle: During the fire extinguishing process of the charging pile, the movement of the A-shaped plate 158 drives the push rod 163 to move. The push rod 163 contacts the L-shaped plate 166 and exerts an upward pushing force on the L-shaped plate 166, causing the L-shaped plate 166 to rotate clockwise. The rotation of the L-shaped plate 166 drives the rotating rod 165 to rotate, which in turn drives the striking plate 167 to rotate, thereby striking and vibrating the surface of the dry powder box 151. This breaks the sealing structure of the dry powder box 151, allowing the dry powder extinguishing agent to be released quickly, preventing the dry powder from becoming damp and clumping, which would prevent it from being released properly. At the same time, the brush plate 13 moves towards... The upward movement causes the inclined block 168 to move upward. During the movement, the inclined block 168 will come into contact with the limiting block 161 and exert a squeezing force on the limiting block 161, causing the limiting block 161 to move to the left. The moving limiting block 161 will come into contact with the partition door 162. After moving a certain distance, the partition door 162 will slide out through the inner wall of the limiting block 161 and release the limiting force on the partition door 162, allowing the partition door 162 to move downward by gravity. This can close the ventilation window 3, thereby isolating the airflow between the inside and outside of the charging pile and reducing the oxygen content inside the charging pile, thus reducing the further expansion of the internal flame.
