Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and specifically to a new energy charging pile with a self - protection function. Background Art

[0002] With the rapid development of the global new energy vehicle industry, the number of charging piles is also increasing continuously. Charging pile technology will develop in the direction of higher power, more intelligent and more convenient. On the one hand, high - power fast - charging technology will continue to mature and popularize, shortening the charging time.

[0003] The patent with the publication number CN214492576U relates to a charging pile with heat dissipation and anti - theft functions, including a charging pile body and a base; Base: Air outlet holes are arranged in a rectangular array on both the front and rear sides. A wireless transceiver module is fixed to the lower side inside the base, and ground - entering screws are screwed through both the left and right ends of the base; Charging pile body: The lower end is inserted into the upper end of the base. Air inlet holes are arranged on both the front and rear sides of the upper end of the charging pile body. Air passing holes are arranged in a linear array on the lower side of the charging pile body. A fan is fixed to the lower side of the charging pile body, and the fan is directly below the air passing holes. Side shells are fixed to both the left and right sides of the charging pile body. The charging pile with heat dissipation and anti - theft functions can first ventilate the inside of the charging pile and avoid direct sunlight, thereby dissipating heat from the charging pile. It can also hold the ground - entering nails connected to the ground after installing the charging pile, preventing the ground - entering nails from being pulled out, and thus preventing the charging pile from being stolen. However, when the device is hit, the charging pile will be subjected to a large impact force, and thus is prone to collapse, get damaged, and cause safety problems such as the charging pile catching fire. Therefore, a new energy charging pile with a 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 a self - protection function for the deficiencies in the above - mentioned prior art.

[0005] To solve the above 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. The inner wall of the charging pile body is rotatably connected with a cabinet door, and the inner wall of the charging pile body is fixedly connected with a ventilation window. The front part of the charging pile body is fixedly connected with an elastic telescopic column, and the circumferential surface of the telescopic end of the elastic telescopic column is fixedly connected with a buffer plate. The inner wall of the buffer plate is fixedly connected with a straight plate. The inner wall of the charging pile body is fixedly connected with a support frame. The top of the straight plate is fixedly connected with an inclined flat plate. The inner wall of the support frame is slidably connected with a T - shaped inclined plate. The top of the T - shaped inclined plate is fixedly connected with a clamping plate. The inner wall of the charging pile body is fixedly connected with a motor, and the output end of the motor is rotatably connected with a lead screw. The circumferential surface of the lead screw is movably connected with a brush plate. A smoke detector is installed on the inner wall of the charging pile body. A fire - prevention device for preventing fire is arranged on the inner wall of the charging pile body. A partition device for isolating oxygen is arranged on the left side of the charging pile body. The inner wall of the charging pile body is slidably connected with the surface of the straight plate. The bottom of the T - shaped inclined plate is in contact with the top of the inclined flat plate. The surface of the clamping 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 with the motor. When the charging pile is impacted, it can reduce the impact force received by the charging pile to a certain extent, thereby protecting the charging pile to a certain extent. At the same time, it can lock the cabinet door to prevent the cabinet door from rotating into the interior of the charging pile after the charging pile is impacted, which may cause a short - circuit of the electronic components inside the charging pile and then trigger a fire. It can also prevent unauthorized personnel from opening the charging pile, resulting in potential safety risks. During the 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, resulting in poor air circulation and then causing the temperature inside the charging pile to be too high, affecting the normal use of the charging pile.

[0006] Preferably, the fire prevention device includes a dry powder box 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 chute is fixedly connected to the bottom of the dry powder box. An L-shaped baffle is slidably connected to the inner wall of the chute. A connecting plate is fixedly connected to the right side of the brush plate. 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. 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. A transmission wheel is rotatably connected to the central axis of the brush roller. The bottom of the dry powder box is in contact with the top of the L-shaped baffle. The bottom of the movable door is in contact with the top of the L-shaped baffle. The top of the triangular plate is in contact with the bottom of the angled plate. The top of the connecting plate is in contact with the bottom of the A-shaped plate. The left side of the ventilation window is in contact with the circumferential surface of the transmission wheel. When a fire or the smoke generated by a fire appears inside the charging pile, the dry powder in the dry powder box can be sprinkled onto the location of the fire, thereby quickly controlling the fire and preventing the fire from rapidly expanding in a short time, thus winning precious time for personnel evacuation and further rescue work. At the same time, the rotation of the transmission wheel drives the rotation of the brush roller, which can further improve the ventilation effect of the ventilation window and avoid the situation that the internal temperature of the charging pile is too high due to the blockage of the ventilation window.

[0007] Preferably, the partition device includes a limit block slidably connected to the inner wall of the charging pile body. A partition door is slidably connected to the inner wall of the ventilation window. A push rod is fixedly connected to the inner wall of the A-shaped plate. A fixed block is fixedly connected to the left side of the dry powder box. A rotating rod is rotatably connected to the inner wall of the fixed block through a torsion spring. An L-shaped plate is fixedly connected to the circumferential surface of the rotating rod. A knocking plate is fixedly connected to the circumferential surface of the rotating rod. An inclined block is fixedly connected to the top of the brush plate. The surface of the limit block is in contact with the inner wall of the partition door. The right side of the ventilation window is in contact with the left side of the inclined block. During the fire extinguishing process of the charging pile, the rotation of the rotating rod drives the rotation of the knocking plate, thereby knocking on the surface of the dry powder box and generating vibration, which can break the sealing structure of the dry powder box and quickly release the dry powder extinguishing agent, avoiding partial moisture caking of the dry powder, resulting in abnormal release. At the same time, the partition door moves downward by gravity, which can close the ventilation window to isolate the internal and external air circulation of the charging pile, thereby reducing the oxygen content inside the charging pile to reduce the further expansion of the internal flame.

[0008] The present invention adopts the above technical solutions and can bring the following beneficial effects: The new energy charging pile with self-protection function can reduce the impact force on the charging pile to a certain extent when the charging pile is hit through the coordinated operation of the charging pile body, cabinet door, ventilation window, elastic telescopic column, buffer plate, straight plate, support frame, inclined flat plate, T-shaped inclined plate, card plate and smoke detector, thereby protecting the charging pile to a certain extent, and can lock the cabinet door to prevent the cabinet door from rotating toward the inside of the charging pile after the charging pile is hit, thereby causing a short circuit in the electronic components inside the charging pile and causing a fire, and can also prevent unrelated personnel from opening the charging pile to cause potential safety risks.

[0009] 2. The new energy charging pile with self-protection function works through the coordination of the motor, the screw rod and the brush plate. During the normal use of the charging pile, the brush plate moves upward when the screw rod rotates clockwise, thereby preventing the ventilation window from being blocked by dust and debris, causing poor air circulation, and causing the temperature inside the charging pile to be too high, affecting the normal use of the charging pile.

[0010] 3. The new energy charging pile with self-protection function can sprinkle the dry powder in the dry powder box to the location of the fire when flames or smoke generated by fire appear inside the charging pile through the coordinated operation of the dry powder box, movable door, slide groove, L-shaped baffle, connecting plate, triangle plate, bevel plate, A-shaped plate, fixed plate, brush roller and transmission wheel, so as to quickly control the fire and prevent the fire from spreading rapidly in a short time, thereby buying precious time for personnel evacuation and further rescue work. At the same time, the rotation of the transmission wheel drives the brush roller to rotate, thereby further improving the ventilation effect of the ventilation window and avoiding the situation where the temperature inside the charging pile is too high due to blockage of the ventilation window.

[0011] 4. The new energy charging pile with self-protection function cooperates with the limit block, partition door, push rod, fixed block, rotating rod, L-shaped plate, knocking plate and inclined block. During the fire extinguishing process of the charging pile, the rotating rod rotates to drive the knocking plate to rotate, thereby knocking on the surface of the dry powder box and generating vibration, which will break the sealing structure of the dry powder box, so that the dry powder fire extinguishing agent is quickly released to prevent part of the dry powder from getting damp and agglomerating, resulting in failure to release normally. At the same time, the partition door moves downward by gravity, so that the ventilation window can be closed to isolate the circulation of air inside the charging pile from the outside, thereby reducing the oxygen content inside the charging pile to reduce the further expansion of the internal flame.

Detailed implementation manners

[0014] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0015] Please refer to Figures 1-9, an embodiment of the present invention is: a new energy charging pile with self - protection function, including a charging pile body 1. The inner wall of the charging pile body 1 is rotatably connected with a cabinet door 2, and the inner wall of the charging pile body 1 is fixedly connected with a ventilation window 3. The front part of the charging pile body 1 is fixedly connected with an elastic telescopic column 4. The circumferential surface of the telescopic end of the elastic telescopic column 4 is fixedly connected with a buffer plate 5. 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 being able to reduce the impact force received by the charging pile to a certain extent, and then protecting the charging pile to a certain extent. The inner wall of the buffer plate 5 is fixedly connected with a straight plate 6, and the inner wall of the charging pile body 1 is fixedly connected with a support frame 7. The top of the straight plate 6 is fixedly connected with an inclined flat plate 8. The inner wall of the support frame 7 is slidably connected with a T - shaped inclined plate 9. The top of the T - shaped inclined plate 9 is fixedly connected with a clamping plate 10. At the same time, the backward movement of the buffer plate 5 drives the straight plate 6 to move backward, and the backward movement of the straight plate 6 drives the inclined flat plate 8 to move backward. During the movement of the inclined flat plate 8, it will come into contact with the T - shaped inclined plate 9 and squeeze the T - shaped inclined plate 9 upward through the inclined plane, causing the T - shaped inclined plate 9 to move upward. The upward movement of the T - shaped inclined plate 9 drives the clamping plate 10 to move upward, so as to lock the cabinet door 2 to prevent the cabinet door 2 from rotating into the charging pile after the charging pile is impacted, which may cause a short - circuit of the electronic components inside the charging pile and then trigger a fire. It can also prevent unauthorized personnel from opening the charging pile, causing potential safety risks. The inner wall of the charging pile body 1 is fixedly connected with a motor 11. The output end of the motor 11 is rotatably connected with a lead screw 12. The circumferential surface of the lead screw 12 is movably connected with a brush plate 13. A smoke detector 14 is installed on the inner wall of the charging pile body 1. A fire - prevention device 15 for preventing fire is arranged on the inner wall of the charging pile body 1.

The smoke detector 14 is electrically connected with the motor 11. At the same time, during the normal use of the charging pile, the motor 11 will be started regularly. When the motor 11 is started, the motor 11 rotates to drive the lead screw 12 to rotate. The rotation of the lead screw 12 will contact the thread on the surface of the lead screw 12 through the slider arranged inside the brush plate 13. When the lead screw 12 rotates clockwise, the brush plate 13 moves upward, thereby preventing the ventilation window 3 from being blocked by dust and debris, resulting in poor air circulation and then causing the temperature inside 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, the dry powder box 151 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 chute 153 is fixedly connected to the bottom of the dry powder box 151, an L-shaped baffle 154 is slidably connected to the inner wall of the chute 153, a connecting plate 155 is fixedly connected to the right side of the brush plate 13, a triangular plate 156 is fixedly connected to the right side of the connecting plate 155. When a fire or smoke generated by a fire appears inside the charging pile, the smoke will be detected by the smoke detector 14, thereby extending the time for the motor 11 to rotate clockwise, so that the brush plate 13 continues to move upward when it would originally stop, thereby causing the brush plate 13 to drive the connecting plate 155 to move, the connecting plate 155 moves to drive the triangular plate 156 to move, and the triangular plate 156 will come into contact with the bevel plate 157 during the movement and exert a squeezing force on the bevel plate 157 to make the bevel plate 157 move forward. The bevel plate 157 moves forward to drive the L-shaped baffle 154 to move forward, so that the limit of the movable door 152 can be released, so that the dry powder in the dry powder box 151 can be sprinkled on the position of the fire, thereby quickly controlling the fire and preventing the fire from rapidly expanding in a short time, thereby winning precious time for personnel evacuation and further rescue work. An bevel 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, a transmission wheel 1511 is rotatably connected to the central axis 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 bevel plate 157, the top of the connecting plate 155 is in contact with the bottom of the A-shaped plate 158, 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 fixing plate 159 to move, the fixing plate 159 moves to drive the brush roller 1510 to move, the brush roller 1510 moves to drive the transmission wheel 1511 to move, and the transmission wheel 1511 will come into contact with the ventilation window 3 and generate friction during the movement, so that the transmission wheel 1511 rotates, and 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 that the inside temperature of the charging pile is too high due to the blockage of the ventilation window 3.

[0017] Working principle: when the charging pile is hit, the vehicle will generate an impact force on the buffer plate 5, causing the buffer plate 5 to move backward. The buffer plate 5 will be buffered by the elastic telescopic column 4 when it moves backward, thereby reducing the impact force on the charging pile to a certain extent, and then protecting the charging pile to a certain extent. At the same time, the buffer plate 5 moves backward, driving the straight plate 6 to move backward, and the straight plate 6 moves backward, driving the inclined plate 8 to move backward. During the movement of the inclined plate 8, it will contact the T-shaped inclined plate 9, and squeeze the T-shaped inclined plate 9 through the inclined surface, so that the T-shaped inclined plate 9 moves upward. The upward movement of the T-shaped inclined plate 9 drives the card plate 10 to move upward, thereby locking the cabinet door 2 to avoid the charging pile being hit. , the cabinet door 2 rotates toward the inside of the charging pile, thereby causing a short circuit in the electronic components inside the charging pile, thereby causing a fire. It can also prevent unrelated personnel from opening the charging pile, causing potential safety risks. At the same time, during the normal use of the charging pile, the motor 11 will start regularly. When the motor 11 is started, the motor 11 rotates to drive the screw rod 12 to rotate. The rotation of the screw rod 12 will contact the thread on the surface of the screw rod 12 through the slider arranged inside the brush plate 13, so that the brush plate 13 moves upward when the screw rod 12 rotates clockwise, thereby preventing the ventilation window 3 from being blocked by dust and debris, resulting in poor air circulation, thereby causing the temperature inside the charging pile to be too high, affecting the normal use of the charging pile.

[0018] When a flame or smoke is generated by a fire 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 continues to move upward when it would otherwise stop, and the brush plate 13 drives the connecting plate 155 to move, and the movement of the connecting plate 155 drives the triangular plate 156 to move, and the triangular plate 156 will contact the bevel plate 157 during the movement, and generate an extrusion force on the bevel plate 157 to move the bevel plate 157 forward, and the bevel plate 157 moves forward and drives the L-shaped baffle 154 forward, so that the limit of the movable door 152 can be released, so that the dry powder in the dry powder box 151 can be discharged. The brush roller 1510 is moved by the brush plate 13, and the transmission wheel 1511 is moved. During the movement of the transmission wheel 1511, the transmission wheel 1511 will contact with the ventilation window 3 and generate friction, so that the transmission wheel 1511 rotates, and 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 that the temperature inside the charging pile is too high due to the blockage of the ventilation window 3.

[0019] See also Figures 1-9, on the basis of the above embodiments, in another embodiment of the present invention, the partition device 16 includes a limit block 161, the limit block 161 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, and a rotating rod 165 is rotatably connected to the inner wall of the fixing block 164 through a torsion spring. During the process of extinguishing the fire in the charging pile, the movement of the A-shaped plate 158 drives the movement of the push rod 163. The movement of the push rod 163 will contact the L-shaped plate 166 and generate an upward thrust 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 rotation of the rotating rod 165, and the rotation of the rotating rod 165 drives the rotation of the knocking plate 167, thereby knocking on the surface of the dry powder box 151 and generating vibration, and further breaking the sealing structure of the dry powder box 151, so that the dry powder fire extinguishing agent is quickly released, avoiding partial moisture caking of the dry powder, resulting in abnormal release. An L-shaped plate 166 is fixedly connected to the circumferential surface of the rotating rod 165, and a knocking plate 167 is fixedly connected to the circumferential surface of the rotating rod 165. An inclined block 168 is fixedly connected to the top of the brush plate 13. The surface of the limit 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 inclined block 168. At the same time, the upward movement of the brush plate 13 drives the upward movement of the inclined block 168. During the movement of the inclined block 168, it will contact the limit block 161 and generate an extrusion force on the limit block 161, causing the limit block 161 to move to the left. The movement of the limit block 161 will contact the partition door 162, and after a certain moving distance, the partition door 162 will slide out through the inner wall of the limit block 161 and release the limit on the partition door 162, so that the partition door 162 moves downward by gravity, thereby closing the ventilation window 3 and isolating the circulation of air inside and outside the charging pile, and further reducing the oxygen content inside the charging pile to reduce the further expansion of the internal flame.

[0020] Working principle: During the process of extinguishing the fire in the charging pile, the movement of the A-shaped plate 158 drives the movement of the push rod 163. The movement of the push rod 163 will contact the L-shaped plate 166 and generate an upward thrust 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 rotation of the rotating rod 165, and the rotation of the rotating rod 165 drives the rotation of the knocking plate 167, thereby knocking on the surface of the dry powder box 151 and generating vibrations, which will then break the sealing structure of the dry powder box 151, enabling the rapid release of the dry powder fire extinguishing agent, avoiding partial moisture caking of the dry powder, which may lead to abnormal release. At the same time, the upward movement of the brush plate 13 drives the upward movement of the inclined block 168. During the movement of the inclined block 168, it will come into contact with the limit block 161 and generate a squeezing force on the limit block 161, causing the limit block 161 to move to the left. The movement of the limit block 161 will contact the partition door 162, and after a certain moving distance, the partition door 162 will slide out through the inner wall of the limit block 161 and the limit on the partition door 162 will be released, causing the partition door 162 to move downward due to gravity, thereby closing the ventilation window 3, enabling the isolation of the air circulation between the inside and outside of the charging pile, and further reducing the oxygen content inside the charging pile to reduce the further expansion of the internal flame.
