Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and specifically to a mobile energy storage charging pile. Background Art

[0002] In recent years, with the popularization of new energy vehicles, the long charging time has also affected people's long-distance travel. When the vehicle runs out of power on the road and cannot continue to drive, emergency rescue is often called. Generally, the rescue method is to use a mobile energy storage charging pile to charge the vehicle to be rescued.

[0003] The existing mobile energy storage charging pile, also known as a car power bank, is usually directly mounted on a vehicle and moves with the vehicle. Since the internal space of a vehicle such as a minivan is limited and the air circulation is poor, the heat dissipation effect of the mobile energy storage charging pile is not good when charging a new energy vehicle to be rescued. Moreover, the existing heat dissipation methods of the mobile energy storage charging pile are air-cooled heat dissipation by a fan and liquid-cooled heat dissipation. The former has limited heat dissipation effect, and the latter has high requirements for pipeline layout and a risk of leakage. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention provides a mobile energy storage charging pile, which solves the problems raised in the above background art.

[0005] To achieve the above objectives, the present invention is realized through the following technical solutions: A mobile energy storage charging pile includes a charging pile body and a cooling component. An air inlet pipe is connected to the back of the charging pile body. The cooling component includes a drying box connected to the end of the air inlet pipe. The bottom of the drying box is connected to a coolant tank through a pipeline. On the upper surface of the coolant tank, a three-way valve pipe is connected to the side away from the pipeline, and the end of the three-way valve pipe is connected to a fan. An air delivery pipe is connected to the side of the fan. A bearing pipe is provided at the top of the air delivery pipe. A rotating carrier plate is rotatably connected to the top of the bearing pipe. A wind vane is provided in the middle of the surface of the rotating carrier plate. An air inlet hopper is provided through the surface of the rotating carrier plate. A filter screen is embedded in the air inlet hopper. A bearing sleeve is rotatably connected to the outer wall of the rotating carrier plate, and the bearing sleeve is fixed to the top of the vehicle.

[0006] Further, the air inlet hopper is communicated with the air delivery pipe through the bearing pipe, and the air delivery pipe is communicated with the inside of the coolant tank through the fan and the three-way valve pipe.

[0007] Further, the interiors of the coolant tank and the drying box are each divided into two chambers by a partition, and activated carbon is provided in the two chambers inside the drying box.

[0008] Further, the two chambers inside the coolant tank are respectively a first chamber and a second chamber, and the first chamber and the second chamber are respectively communicated with the pipelines at both ends of the bottom of the three-way valve pipe.

[0009] Furthermore, the first chamber and the second chamber are internally provided with coolant, and the pipes at both ends of the bottom of the three-way valve pipe extend into the coolant.

[0010] Furthermore, temperature sensors are provided inside both the first chamber and the second chamber, and a wind speed sensor is provided inside the air inlet pipe.

[0011] Furthermore, an exhaust assembly is provided on the side of the charging pile body. The exhaust assembly includes heat dissipation holes and a gas collecting hood, and the side of the charging pile body is covered with a gas collecting hood outside the heat dissipation holes.

[0012] Furthermore, the exhaust assembly further includes an exhaust pipe. The middle of the surface of the gas collecting hood is connected to the exhaust pipe, and the end of the exhaust pipe passes through the car window and extends outside the car.

[0013] Furthermore, a wire winding assembly is provided on the side of the charging pile body on one side of the gas collecting hood. The wire winding assembly includes a winding turntable and a charging line, and the charging line is wound on the surface of the winding turntable.

[0014] Furthermore, the wire winding assembly further includes a charging plug, and a charging plug is fixed at the end of the charging line.

[0015] The present invention provides a mobile energy storage charging pile, which has the following beneficial effects:

[0016] 1. For this mobile energy storage charging pile, when the charging pile body stops moving and charges the new energy vehicle when it arrives at the destination with the vehicle, the external natural wind drives the wind vane to rotate, so that the opening of the air inlet hopper always faces against the wind and is filtered through the filter screen to collect clean natural wind. The natural wind is pre-cooled through the coolant tank and dehumidified through the drying box, so that the low-temperature and dry natural wind enters the charging pile body to cool it. This method has a more obvious cooling effect compared with air cooling. Compared with water cooling, since the coolant tank and the charging pile body are separately arranged, it can prevent liquid leakage from seeping into the interior of the charging pile body, and at the same time eliminates the complexity of pipeline layout.

[0017] 2. For this mobile energy storage charging pile, by detecting the internal cooling temperature of the first chamber and the second chamber in real time, when the temperature of any chamber is too high during the working state, the transmission path of the three-way valve pipe is switched, so that the natural wind enters the other chamber for pre-cooling. Thus, by circulating and switching, the coolant temperature in a single chamber is prevented from rising and the cooling effect on the interior of the charging pile body is reduced, which is conducive to keeping the external natural wind in a low-temperature state all the time to cool the charging pile body.

Specific embodiments

[0024] The following further describes in detail the embodiments of the present invention in conjunction with the drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0025] Such as Figures 1 - 5As shown in the figure, the present invention provides a technical solution: a mobile energy storage charging pile, including a charging pile body 1 and a cooling component 3. An air inlet pipe 2 is connected to the back of the charging pile body 1. The cooling component 3 includes a drying box 301 connected to the end of the air inlet pipe 2. The bottom of the drying box 301 is connected to a coolant tank 302 through a pipe. One side of the upper surface of the coolant tank 302 away from the pipe is connected to a three-way valve pipe 303. The end of the three-way valve pipe 303 is connected to a fan 304. An air delivery pipe 305 is connected to the side of the fan 304. A bearing pipe 306 is provided at the top of the air delivery pipe 305. A rotating carrier plate 307 is rotatably connected to the top of the bearing pipe 306. A wind vane 308 is provided in the middle of the surface of the rotating carrier plate 307. An air inlet hopper 309 penetrates through the surface of the rotating carrier plate 307. A filter screen 310 is embedded in the air inlet hopper 309. A bearing sleeve 311 is rotatably connected to the outer wall of the rotating carrier plate 307, and the bearing sleeve 311 is fixed to the top of the vehicle. The air inlet hopper 309 is communicated with the air delivery pipe 305 through the bearing pipe 306, and the air delivery pipe 305 is communicated with the inside of the coolant tank 302 through the fan 304 and the three-way valve pipe 303. The inside of the coolant tank 302 and the drying box 301 are each divided into two chambers by a partition. Activated carbon is provided in the two chambers inside the drying box 301. The two chambers inside the coolant tank 302 are respectively a first chamber and a second chamber, and the first chamber and the second chamber are respectively communicated with the pipes at both ends of the bottom of the three-way valve pipe 303. Coolant is provided in the first chamber and the second chamber, and the pipes at both ends of the bottom of the three-way valve pipe 303 extend into the coolant. Temperature sensors are provided in both the first chamber and the second chamber. A wind speed sensor is provided inside the air inlet pipe 2;

[0026] The specific operation is as follows. First, make a hole in the top of a vehicle such as a minibus and install the bearing sleeve 311. After the vehicle arrives at the position, stop and charge the new energy vehicle. At this time, the natural wind outside drives the wind vane 308, causing the rotating carrier plate 307 to carry the air inlet hopper 309 to rotate, so that the opening of the air inlet hopper 309 always faces against the wind. At this time, the natural wind outside passes through the filter screen 310 to filter impurities and then passes through the bearing pipe 306, the fan 304, and one end of the bottom of the three-way valve pipe 303 in sequence and enters the first chamber in the coolant tank 302. The coolant in the first chamber is used to pre-cool the natural wind outside. The pre-cooled natural wind passes through the pipe and the activated carbon in the drying box 301 to dehumidify. The dehumidified natural wind enters the inside of the charging pile body 1 along the air inlet pipe 2 to cool it;

[0027] The air inlet pipe 2 is provided with a wind speed sensor. Based on the flow rate of the external natural wind, the output power of the motor is adjusted through a control program to regulate the rotation speed of the fan 304. When only natural wind passes through the air inlet pipe 2 and the wind speed reaches the preset value, the fan 304 stops rotating. The preset value is set according to the actual situation, and it is necessary to ensure that the wind speed of this preset value can effectively cool the charging pile body 1. When the natural wind speed is sufficient and the fan 304 stops rotating, energy can be saved. If the natural wind does not reach the preset value, the rotation speed of the fan 304 is adjusted according to the difference between its actual wind speed and the preset value. The greater the difference, the higher the rotation speed of the fan 304. Thus, the fan 304 actively extracts external air to supplement the wind force;

[0028] Based on the above description, when the charging pile body 1 of the present invention stops moving and charges the new energy vehicle as the vehicle arrives at the destination, the external natural wind drives the wind vane 308 to rotate, so that the opening of the air inlet hopper 309 always faces against the wind and is filtered through the filter screen 310 to collect clean natural wind. The natural wind is pre-cooled by the coolant tank 302 and dehumidified by the drying box 301, so that the low-temperature and dry natural wind enters the charging pile body 1 to cool it. This method has a more obvious cooling effect compared with air cooling. Compared with water cooling, since the coolant tank 302 and the charging pile body 1 are separated, liquid leakage can be prevented from seeping into the interior of the charging pile body 1, and at the same time, the complexity of pipeline layout is eliminated;

[0029] The two chambers inside the coolant tank 302 are respectively the first chamber and the second chamber, and the first chamber and the second chamber are respectively communicated with the pipelines at both ends of the bottom of the three-way valve pipe 303. Temperature sensors are arranged inside the first chamber and the second chamber. When the temperature sensor inside any one of the working chambers in the first chamber and the second chamber detects that the temperature reaches the preset value, this preset value indicates that the pre-cooling effect on the natural wind is reduced due to the increase in the coolant temperature. At this time, the exhaust ends at both ends of the bottom of the three-way valve pipe 303 are switched on. For example, when the temperature inside the first chamber reaches the preset value, at this time, the three-way valve pipe 303 injects the natural wind into the second chamber. The first chamber is in a static cooling state at this time, and the coolant in the second chamber is used to continue to cool and pre-cool the natural wind. The first chamber and the second chamber are separated by a heat-insulating partition such as a ceramic plate to prevent heat transfer;

[0030] Based on the above description, by detecting the internal cooling temperature of the first chamber and the second chamber in real time, when the temperature of any one of the working chambers is too high, the transmission path of the three-way valve pipe 303 is switched, so that the natural wind enters another chamber for pre-cooling. Thus, by cyclic switching, the coolant temperature in a single chamber is prevented from rising and the cooling effect on the interior of the charging pile body 1 is reduced, which is beneficial to always keeping the external natural wind in a low-temperature state to cool the charging pile body 1.

[0031] Such as Figures 1 - 5As shown, an exhaust component 4 is provided on the side of the charging pile body 1. The exhaust component 4 includes a heat dissipation hole 401 and a gas collecting hood 402. The gas collecting hood 402 is wrapped outside the heat dissipation hole 401 on the side of the charging pile body 1. The exhaust component 4 further includes an exhaust pipe 403. The middle of the surface of the gas collecting hood 402 is connected to the exhaust pipe 403, and the end of the exhaust pipe 403 passes through the car window and extends outside the car.

[0032] The specific operation is as follows. The low-temperature natural wind that enters the charging pile body 1 absorbs heat and then passes through the heat dissipation hole 401 and enters the interior of the exhaust pipe 403 along the gas collecting hood 402. The exhaust pipe 403 is a flexible pipe, and its end passes through the car window and is placed in the parking space. Therefore, it is beneficial to directly discharge the high-temperature natural wind after heat absorption outside the car, thereby preventing heat from directly accumulating in the car.

[0033] As Figures 1 - 5 shown, a wire winding component 5 is provided on one side of the gas collecting hood 402 on the side of the charging pile body 1. The wire winding component 5 includes a winding turntable 501 and a charging line 502. The charging line 502 is wound on the surface of the winding turntable 501. The wire winding component 5 further includes a charging plug 503. The end of the charging line 502 is fixed with the charging plug 503.

[0034] The specific operation is as follows. When performing rescue charging for a new energy vehicle, manually hold the charging plug 503 and pull it outwards. At this time, under the action of the pulling force, the winding turntable 501 rotates, causing the charging line 502 to be released. After the length of the charging line 502 released is appropriate, manually hold the charging plug 503 and insert it into the charging port of the new energy vehicle, thereby charging the new energy vehicle. After charging is completed, unplug the charging plug 503, and then manually rotate the winding turntable 501 in the reverse direction to wind up the excess part of the charging line 502, making the storage of the charging line 502 beautiful and preventing the charging line 502 and the charging plug 503 from shaking and colliding during vehicle driving due to random storage and placement.

[0035] In summary, for this mobile energy storage charging pile, when in use, first, when performing rescue charging for a new energy vehicle, manually hold the charging plug 503 and pull it outwards. At this time, under the action of the pulling force, the winding turntable 501 rotates, causing the charging line 502 to be released. After the length of the charging line 502 released is appropriate, manually hold the charging plug 503 and insert it into the charging port of the new energy vehicle, thereby charging the new energy vehicle. After charging is completed, unplug the charging plug 503, and then manually rotate the winding turntable 501 in the reverse direction to wind up the excess part of the charging line 502.

[0036] During charging, the external natural wind drives the wind vane 308, causing the rotating carrier plate 307 to carry the air inlet hopper 309 to rotate, so that the opening of the air inlet hopper 309 always faces against the wind. At this time, the external natural wind passes through the filter screen 310 to filter impurities and then passes through the bearing pipe 306, the fan 304, and one end of the bottom of the three-way valve pipe 303 in sequence and enters the first chamber in the coolant tank 302. The coolant in the first chamber is used to pre-cool the external natural wind. The pre-cooled natural wind passes through the pipeline and the activated carbon in the drying box 301 to dehumidify. The dehumidified natural wind enters the inside of the charging pile body 1 along the air inlet pipe 2 to cool it down;

[0037] A wind speed sensor is provided in the air inlet pipe 2. Based on the flow velocity of the external natural wind, the output power of the motor is adjusted through the control program to regulate the rotation speed of the fan 304. When only natural wind passes through the air inlet pipe 2 and the wind speed reaches the preset value, the fan 304 stops rotating. The preset value is set according to the actual situation and needs to ensure that the wind speed of the preset value can effectively cool the charging pile body 1. If the natural wind does not reach the preset value, the rotation speed of the fan 304 is adjusted according to the difference between the actual wind speed and the preset value. The greater the difference, the higher the rotation speed of the fan 304. Thus, the fan 304 actively extracts external air to supplement the wind force;

[0038] The two chambers inside the coolant tank 302 are the first chamber and the second chamber respectively. The first chamber and the second chamber are respectively connected to the pipelines at both ends of the bottom of the three-way valve pipe 303. Temperature sensors are arranged inside the first chamber and the second chamber. When the internal temperature sensor in any of the working chambers in the first chamber and the second chamber detects that the temperature reaches the preset value, this preset value indicates that the pre-cooling effect of the natural wind is reduced due to the increase in the coolant temperature. At this time, the exhaust ends at both ends of the bottom of the three-way valve pipe 303 are switched on. For example, when the internal temperature of the first chamber reaches the preset value, at this time, the three-way valve pipe 303 injects the natural wind into the second chamber. The first chamber is in a static cooling state at this time, and the coolant in the second chamber is used to continue to cool and pre-cool the natural wind;

[0039] The low-temperature natural wind entering the inside of the charging pile body 1 absorbs heat and then passes through the heat dissipation holes 401 and enters the inside of the exhaust pipe 403 along the air collecting cover 402. The exhaust pipe 403 is a flexible pipe, and its end passes through the car window and is placed in the parking space. Therefore, it is beneficial to directly discharge the high-temperature natural wind after absorbing heat outside the car, thus preventing heat from directly accumulating inside the car;

[0040] Finally, a protective cover can be added to the top of the vehicle. The protective cover can be opened and closed by electric telescoping to facilitate the storage of the wind vane 308 or expose it, so as to prevent the wind vane 308 from being exposed and damaged in bad weather. Micro holes can be opened on the surface of the protective cover to prevent it from interfering with the fan 304 from sucking in external air.

Many modifications and variations are obvious to those of ordinary skill in the art.
