Description

Technical Field

[0001] The present invention belongs to the technical field of charging piles, and specifically relates to a new energy energy storage charging safety device. Background Art

[0002] At present, the power sources of photovoltaic charging piles on the market are all built on the rooftop photovoltaic power stations on the roofs of charging station canopies or surrounding buildings. Photovoltaic charging piles can be used in relatively remote places without the need for additional power grids. Since photovoltaic charging piles need to convert light energy into chemical energy and store it in internal storage batteries, essentially, the internal storage batteries supply power to electric vehicles.

[0003] A photovoltaic charging pile safety device with the application number CN202320248597.6 reduces the accumulation of heat inside the device by reducing its own heat generation to avoid spontaneous combustion problems. However, when the storage battery supplies power to the electric vehicle, the external wiring terminal part is most likely to catch fire due to charger failures, which will affect the internal battery components. And it is necessary to carry out comprehensive replacement and maintenance work on the components, which is inconvenient to use and has a low safety factor, so improvements are needed. Summary of the Invention

[0004] In view of the problem that the prior art cannot effectively isolate and prevent fire, the technical solution adopted by the present invention is: a new energy energy storage charging safety device, including a protection component. The protection component includes: A docking cylinder shell, which is composed of the upper shell and the lower shell docked and combined, and an external clamping part is arranged on the outer surface of the docking cylinder shell; A storage battery, which is in a ring-shaped structure. Transmission connectors are arranged on both sides of the upper part of the storage battery, and power supply connectors are arranged on both sides of the side surface of the storage battery. And a side-position connecting rod is installed on the outer surface of the power supply connector. The end of the side-position connecting rod far away from the storage battery extends to the outside of the docking cylinder shell and is docked with an external photovoltaic panel. The electric energy generated by the photovoltaic panel is stored in the internal of the storage battery, and then the storage battery supplies power to an external battery. A transfer circular shell, and an internal cooling device is installed at the bottom of the transfer circular shell, and the internal cooling device cools the inside of the transfer circular shell; An external connecting part, which is directly connected to an external electric vehicle connector and supplies power; A conductive component, which is arranged inside the transfer circular shell, connects the storage battery and the external connecting part, enables the external connecting part to supply power, and can actively physically separate the external connecting part from the internal storage battery when an external electric vehicle or wire catches fire, preventing the flame from burning into the interior along the wire and causing the explosion of the storage battery.

[0005] The conductive component includes, An annular guide plate, wherein the upper and lower sides of the inner wall of the annular guide plate are installed in the middle of the inner wall of the adapter shell through annular grooves, and the front and rear sides of the outer surface of the annular guide plate are fixedly connected to the power transmission connector on the upper part of the energy storage battery through fixed guide rods; The limiting component is non-conductive and is used to limit and fix the bottom of the external guide; The inner plate is conductive and connected to the annular guide plate to transmit current to the external conductor. The docking component is conductive, docks with the bottom of the external conductor, and directly supplies power to the external conductor.

[0006] The conductive component directly performs the conductive function, and transmits the electric energy inside the energy storage battery to the external conductive component, which then supplies power to the external electric vehicle.

[0007] The limiting components include: A docking sliding shell, the docking sliding shell is made of insulating plastic, the number of the docking sliding shells is four, and the bottom of the outer surface of the docking sliding shell is slidably connected to the top of the transfer round shell through a slide groove. After the docking sliding shells on both sides are docked along the slide groove on the upper part of the transfer round shell, the bottom of the external guide can be clamped in a fixed position, so that the external guide can stably supply power to the outside; A plug-in sleeve, which is installed on the upper surface of the docking sliding shell and is used to install the control component; The annular groove bayonet has a bottom end fixedly connected to the top of the inner cavity of the docking sliding shell and directly engaged with the bottom end of the conductive component.

[0008] The guide inner plate comprises: Arc guide plates, the number of which is two, and the upper surface of the arc guide plates is slidably connected to the bottom of the inner wall of the docking sliding shell, and the bottom of the inner cavity of the arc guide plates is fixedly connected to the inner cavity of the annular guide plates through a secondary guide rod; A guide rod ring, the front and rear ends of which are respectively fixedly connected to the inner cavities of the arc-shaped guide plates on both sides.

[0009] The docking component comprises: A built-in guide plate, the built-in guide plate is fixedly mounted on the upper part of the inner wall of the docking sliding shell; The sliding sleeve is conductive, and the inner wall of the sliding sleeve is slidably connected to the outer surface of the guide rod ring.

[0010] The control component comprises: The telescopic connecting tube is a hollow folding rubber tube, and the bottom end of the telescopic connecting tube is plugged into the inner wall of the ring groove bayonet; A control air pump, wherein the bottom end of the air delivery port of the control air pump is plugged into the middle of the inner cavity of the telescopic connecting pipe through the through hole; A temperature sensing controller, wherein a temperature sensing plate is fixedly installed on the top of the temperature sensing controller, and the temperature sensing plate is installed on the upper surface of the docking tube shell, the outer surface of the temperature sensing controller is fixedly connected to the top of the inner wall of the docking tube shell, and the outer surface of the control air pump is fixedly connected to the outer surface of the control air pump. The temperature sensing controller can directly control the control air pump at the bottom. When the control air pump draws pressure from the inside of the telescopic connecting tube, the telescopic connecting tube will shrink due to the reduction in internal pressure, thereby driving the docking sliding shells on both sides to slide. At this time, the docking sliding shell fixed at the bottom end of the modified wire is separated, and the bottom end of the modified wire is separated from the built-in guide plate, thereby causing power failure inside the external guide.

[0011] The external guide member comprises: The bottom of the outer surface of the modified wire is clamped with the inner wall of the ring groove, the bottom end of the modified wire is plugged with the upper surface of the built-in guide plate through the conductive protrusion, and the top end of the modified wire extends to the outside of the docking tube shell; A compression spring cylinder, the compression spring cylinder being mounted on the upper surface of the docking cylinder shell; A clamping ring plate, the clamping ring plate is installed on the top of the compression spring tube, and the axis of the inner wall of the clamping ring plate is plugged into the outer surface of the modified wire through a clamping groove; When the bottom end of the modified wire is no longer clamped by the docking sliding shell, the compression spring tube will stretch due to its own elasticity, and then pull the modified wire out from the inside of the docking tube shell through the clamping ring plate.

[0012] The internal cooling device comprises: An expansion sleeve, the top of which is fixedly connected to the bottom of the adapter shell, and the bottom of the inner cavity of the adapter shell is evenly provided with through drainage ports; An axial motor, the bottom of which is mounted at the axial center of the bottom of the inner wall of the docking cylinder shell, and the top of the output shaft of the axial motor extends to the inside of the adapter shell through the through opening; The inner wall of the clustering ring sleeve is sleeved with the outer surface of the output shaft of the axial motor, and the inner wall of the clustering ring sleeve is evenly provided with oblique fan blades, and the side parts of the oblique fan blades are bent downward.

[0013] The beneficial effects of the present invention are as follows: 1. The device can supply power to the external tram through a power supply system consisting of energy storage batteries, conductive parts and modified wires. When the external wiring terminal catches fire due to the charging connector or other improper operations, and the flame spreads along the modified wire to the inside of the device, the docking sliding shell will loosen the bottom of the modified wire and drive the built-in guide plate to be physically separated from the bottom of the modified wire, so that the flame spreading along the modified wire will not contact the conductive parts, let alone the energy storage battery deep inside, thereby avoiding the problem of high-temperature explosion caused by the contact between the battery and the flame.

[0014] 2. Since the bottom end of the modified wire is connected to the conductive component by clamping it with a docking sliding shell, when the modified wire fails, you only need to loosen the docking sliding shell and pull out the modified wire for replacement. The high-temperature colloid generated by the burning of the wire will drip onto the inside of the adapter round shell and will not contact the relevant wiring parts of the conductive component, thereby avoiding the problem of poor conductive contact of the conductive component due to contact with the glue dripping from the outer skin of the wire.

[0015] 3. After the modified wire catches fire, since the bottom end of the modified wire is loosened, the compression spring tube in the squeezed state quickly extends and resets under the action of its own elastic potential energy, and then the modified wire is completely pulled out from the inside of the docking tube shell through the clamping ring plate, thereby ensuring that the flame spreading on the outer surface of the modified wire will not burn the internal conductive parts due to the high temperature when it burns to the bottom end of the modified wire, and the flame retardant effect of the compression spring tube can prevent the external flame from directly spreading to the inside of the docking tube shell.

[0016] 4. Since the energy storage battery will supply power to the outside through the annular guide plate, the annular guide plate will continue to heat up when supplying power. At this time, the axis motor at the bottom will drive the cluster ring to rotate clockwise at high speed, so that the airflow inside the adapter shell will be guided downward through the drainage port by the oblique fan blades, and the annular guide plate will be cooled by the internal wind force. The wind force can also remove impurities inside the adapter shell, clean the inner wall of the adapter shell, and avoid the problem of dust accumulation inside the adapter shell.

[0020] Example 1, please refer to Figures 1-7 , the present invention provides a technical solution: a new energy storage charging safety device, including a protection component 1, The protection component 1 includes: A docking cylinder shell 11, which is composed of the upper shell and the lower shell docked and combined, and an external clamping part 15 is arranged on the outer surface of the docking cylinder shell 11; An energy storage battery 13, which is in a ring-shaped structure. Transmission connectors are arranged on both sides of the upper part of the energy storage battery 13, and power supply connectors are arranged on both sides of the side of the energy storage battery 13. And an external clamping part 15 is installed on the outer surface of the power supply connector. One end of the lateral connecting rod 14 away from the energy storage battery 13 extends to the outside of the docking cylinder shell 11 and is docked with an external photovoltaic panel. The electric energy generated by the photovoltaic panel is stored in the energy storage battery 13, and then the energy storage battery 13 supplies power to an external battery; An adapter circular shell 12, and an internal cooling device 5 is installed at the bottom of the adapter circular shell 12, and the internal cooling device 5 cools the inside of the adapter circular shell 12; An external connecting component 3, which is directly connected to an external tram connector and supplies power; The conductive component 2 is arranged inside the adapter circular shell 12, connecting the energy storage battery 13 with the external conducting component 3, enabling the external conducting component 3 to supply power. When an external tram or wire catches fire, it can actively physically separate the external conducting component 3 from the internal energy storage battery 13, preventing the flame from burning into the interior along the wire and causing the explosion of the energy storage battery 13.

[0021] The conductive component 2 includes An annular guide plate 21, both the upper and lower sides of the inner wall of the annular guide plate 21 are installed in the middle of the inner wall of the adapter circular shell 12 through circumferential cutting grooves, and both the front and rear sides of the outer surface of the annular guide plate 21 are fixedly connected to the power transmission connectors on the upper part of the energy storage battery 13 through fixed guide rods 22; A limiting component 25, which is non-conductive and limits and fixes the bottom of the external conducting component 3; A conducting inner disk 23, which is conductive, docks with the annular guide plate 21 and transmits current to the external conducting component 3; A docking component 24, which is conductive, docks with the bottom of the external conducting component 3 and directly supplies power to the external conducting component 3.

[0022] The conductive component 2 directly functions as conduction. After transmitting the electric energy inside the energy storage battery 13 to the external conducting component 3, the external conducting component 3 then supplies power to the external tram.

[0023] The limiting component 25 includes Docking sliding shells 251, the docking sliding shells 251 are made of insulating plastic, the number of docking sliding shells 251 is four, and the bottom of the outer surface of the docking sliding shells 251 is slidably connected to the top of the adapter circular shell 12 through sliding grooves. After the two side docking sliding shells 251 are docked along the sliding grooves on the upper part of the adapter circular shell 12, the bottom of the external conducting component 3 can be clamped in a fixed position, thereby enabling the external conducting component 3 to stably supply power externally; Insertion sleeves 252, which are installed on the upper surface of the docking sliding shells 251 for installing the control component 4; Ring groove bayonets 253, the bottom end of the ring groove bayonets 253 is fixedly connected to the top of the inner cavity of the docking sliding shells 251 and is directly clamped to the bottom end of the conductive component 2.

[0024] The conducting inner disk 23 includes Arc-shaped guide plates 231, the number of arc-shaped guide plates 231 is two, and the upper surface of the arc-shaped guide plates 231 is slidably connected to the bottom of the inner wall of the docking sliding shells 251. The bottom of the inner cavity of the arc-shaped guide plates 231 is fixedly connected to the inner cavity of the annular guide plate 21 through secondary conducting rods; Guide rod rings 232, the front and rear ends of the guide rod rings 232 are respectively fixedly connected to the inner cavities of the two side arc-shaped guide plates 231.

[0025] The docking component 24 includes A built-in guide plate 241, which is fixedly mounted on the upper portion of the inner wall of the docking sliding shell 251; The sliding sleeve 242 is conductive, and the inner wall of the sliding sleeve 242 is slidably connected to the outer surface of the guide rod ring 232 .

[0026] The control component 4 includes, The telescopic connecting tube 41 is a hollow folding rubber tube, and the bottom end of the telescopic connecting tube 41 is plugged into the inner wall of the ring groove bayonet 253; The control air pump 42 has a bottom end of an air delivery port of the control air pump 42 plugged into the middle of the inner cavity of the telescopic connecting tube 41 through a through hole; The temperature sensing controller 43, a temperature sensing plate 44 is fixedly installed on the top of the temperature sensing controller 43, and the temperature sensing plate 44 is installed on the upper surface of the docking tube shell 11, the outer surface of the temperature sensing controller 43 is fixedly connected to the top of the inner wall of the docking tube shell 11, and the outer surface of the control air pump 42 is fixedly connected to the outer surface of the control air pump 42, the temperature sensing controller 43 can directly control the lower control air pump 42, when the control air pump 42 draws pressure from the inside of the telescopic connecting tube 41, the telescopic connecting tube 41 will shrink due to the reduction of internal pressure, thereby driving the docking sliding shells 251 on both sides to slide, at this time, the docking sliding shell 251 fixed on the bottom end of the modified wire 31 is separated, and the bottom end of the modified wire 31 is separated from the built-in guide plate 241, thereby causing the external guide 3 to be powered off.

[0027] The power supply principle of the device is as follows: after the external photovoltaic panel supplies power to the energy storage battery 13 through the side connecting rod 14, the energy storage battery 13 starts to store energy. When the tram needs to be powered, the energy storage battery 13 transmits power through the fixed guide rod 22. After the current flows into the annular guide plate 21, it flows into the arc guide plate 231 from the auxiliary guide connecting rod. At this time, the arc guide plate 231 and the guide rod ring 232 form a closed circuit, and then the current supplies power to the built-in guide plate 241 through the sliding sleeve 242. At this time, the docking sliding shell 251 on the same side is docked and merged together, and reinforced by the control component 4, so the bottom end of the modified wire 31 can be stably docked with the top interface of the built-in guide plate 241, and the modified wire 31 normally transmits current to the external battery to realize power supply.

[0028] When the conductor components at the tram catch fire due to overheating, the temperature sensing plate 44 located outside will sense the high-temperature flame, and then trigger the control air pump 42 at the bottom through the temperature sensing controller 43. The control air pump 42 sucks air into the telescopic connecting tube 41 to shrink the telescopic connecting tube 41, and then the telescopic connecting tube 41 drives the docking sliding shells 251 on both sides to slide along the top sliding groove of the adapter circular shell 12. At this time, the merged adapter circular shells 12 are separated, and the bottom end of the modified conductor 31 cannot be effectively fixed by the ring groove bayonet 253, and the bottom of the modified conductor 31 is separated from the built-in guide plate 241, thereby cutting off the power supply to the modified conductor 31 by physical blocking.

[0029] The bottom end of the modified wire 31 will face the inner wall of the adapter circular shell 12. When the flame spreads along the outer surface of the modified wire 31 to the inside of the docking cylinder shell 11, the liquid colloid after the combustion of the modified wire 31 will drip into the inside of the adapter circular shell 12. The adapter circular shell 12 is used to hold the high-temperature products after the combustion of the modified wire 31. During the whole process, the energy storage battery 13 is completely separated from the modified wire 31, so it will not be affected by the external flame.

[0030] When the docking sliding shell 251 slides along the top chute of the adapter circular shell 12, the sliding sleeve 242 at the bottom separates, but it will slide along the guide rod ring 232 to ensure that the sliding sleeve 242 is always in electrical connection with the guide rod ring 232. After dealing with the external flame, maintenance work needs to be carried out on this device. At this time, open the upper part of the docking cylinder shell 11, take out the remaining external conducting part 3, then pass the bottom end of the new modified wire 31 through the top through-hole of the docking cylinder shell 11, and then manually start the control air pump 42 to pressurize the inside of the telescopic connecting pipe 41. Subsequently, the telescopic connecting pipe 41 expands to push the docking sliding shells 251 on both sides apart. Then the combined docking sliding shells 251 are clamped through the ring groove bayonet 253, and the bottom end of the modified wire 31 is docked with the upper socket of the built-in guide plate 241. At this time, the circuit of the conducting component 2 can supply power to the modified wire 31.

[0031] Example 2, please refer to Figures 1-9 , the present invention provides a technical solution: on the basis of Example 1, the external conducting part 3 includes, The modified wire 31, the bottom of the outer surface of the modified wire 31 is clamped with the inner wall of the ring groove bayonet 253, the bottom end of the modified wire 31 is inserted into the upper surface of the built-in guide plate 241 through the conductive convex head, and the top end of the modified wire 31 extends to the outside of the docking cylinder shell 11; The compression spring cylinder 33, the compression spring cylinder 33 is installed on the upper surface of the docking cylinder shell 11; The clamping ring plate 32, the clamping ring plate 32 is installed on the top of the compression spring cylinder 33, and the axis of the inner wall of the clamping ring plate 32 is inserted into the outer surface of the modified wire 31 through the card slot; When the bottom end of the modified wire 31 is no longer clamped by the docking sliding shell 251, the compression spring cylinder 33 will elongate due to its own elasticity, and then pull out the modified wire 31 from the inside of the docking cylinder shell 11 through the clamping ring plate 32.

[0032] The internal cooling device 5 includes, The expansion sleeve 51, the top of the expansion sleeve 51 is fixedly connected to the bottom of the adapter circular shell 12, and through-drainage ports 52 are uniformly arranged at the bottom of the inner cavity of the adapter circular shell 12; The shaft center motor 53 has its bottom installed at the shaft center of the inner wall bottom of the docking cylinder shell 11, and the top end of the output shaft of the shaft center motor 53 extends into the interior of the adapter circular shell 12 through the through port; The bundled ring sleeve 54 has its inner wall sleeved on the outer surface of the output shaft of the shaft center motor 53, and the inner wall of the bundled ring sleeve 54 is evenly provided with inclined fan blades 55, and the side parts of the inclined fan blades 55 are bent downward.

[0033] After the modified wire 31 catches fire, since the bottom end of the modified wire 31 is loosened, the compression spring cylinder 33 in the compressed state quickly elongates and resets under the action of its own elastic potential energy, and then completely pulls out the modified wire 31 from the interior of the docking cylinder shell 11 through the clamping ring plate 32. Thus, when the flame spreading on the outer surface of the modified wire 31 burns to the bottom end of the modified wire 31, it will not burn the internal conductive component 2 due to the high temperature effect, and the flame retardant effect of the compression spring cylinder 33 can prevent the external flame from directly spreading into the interior of the docking cylinder shell 11. When replacing the modified wire 31, just insert the new modified wire 31 back into the interior of the clamping ring plate 32.

[0034] Since the energy storage battery 13 supplies power to the outside through the annular guide plate 21, the annular guide plate 21 will continuously heat up during power supply. At this time, the shaft center motor 53 at the bottom drives the bundled ring sleeve 54 to rotate clockwise at a high speed, so as to drain the air flow inside the adapter circular shell 12 downward through the through-draining port through the inclined fan blades 55, and perform air cooling on the annular guide plate 21 through the internal wind force.

[0035] 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 and related fields without creative work shall fall within the protection scope of the present invention.
