The rescue method is generally to use a mobile energy storage charging pile to rescue and 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 the vehicle and moves with the vehicle. Due to the limited internal space of the vehicle such as a minivan and poor air circulation, the mobile energy storage charging pile has poor heat dissipation effect when charging the new energy vehicle to be rescued. Moreover, the existing mobile energy storage charging pile uses fan cooling and liquid cooling for heat dissipation. The former has limited heat dissipation effect, and the latter has high requirements for pipeline layout and has a risk of leakage. SUMMARY

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

[0007] Further, the inside of the cooling liquid tank and the drying box is divided into two chambers by a partition plate, and activated carbon is arranged in the two chambers in the drying box.

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

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

[0010] Further, the first chamber and the second chamber are internally provided with temperature sensors, and the inside of the air inlet pipe is provided with an air speed sensor.

[0011] Further, the side of the charging pile body is provided with an exhaust assembly, which comprises a heat dissipation hole and a gas collecting cover, and the side of the charging pile body is covered with the gas collecting cover outside the heat dissipation hole.

[0026] The specific operation is as follows: first, the top of the vehicle such as a van is holed and the bearing sleeve 311 is arranged, the vehicle is parked and stopped after reaching the position and the new energy vehicle is charged, at this time the natural wind drives the wind vane 308 to make the rotating load plate 307 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 three-way valve pipe 303 to enter the first chamber in the cooling liquid tank 302, the cooling liquid in the first chamber is used to precool the natural wind outside, and the pre-cooled natural wind passes through the pipeline and the activated carbon in the drying box 301 to dehumidify, and the dehumidified natural wind enters the inside of the charging pile body 1 through the air inlet pipe 2 to cool it;

[0027] The air inlet pipe 2 is provided with an air speed sensor, based on the flow speed of the external natural wind, the motor output power is adjusted through the control program to adjust the rotating speed of the fan 304, when only the natural wind passes through the air inlet pipe 2, if the air speed reaches the preset value, the fan 304 stops rotating, the preset value is set according to the actual situation, which can ensure that the air speed of the preset value can effectively cool the charging pile body 1, if the natural wind does not reach the preset value, the rotating speed of the fan 304 is adjusted according to the difference between the actual air speed and the preset value, the greater the difference, the higher the rotating speed of the fan 304, so that the external air is actively extracted by the fan 304 to make up the wind power.

[0028] Based on the above description, when the charging pile body 1 stops moving with the vehicle arriving at the destination and charging the new energy vehicle, the wind vane 308 is rotated by the external natural wind, so that the opening of the air inlet hopper 309 is always against the wind and is filtered by the filter screen 310 to collect clean natural wind. The natural wind is pre-cooled by the cooling liquid tank 302 and dehumidified by the drying tank 301, so that the low-temperature and dry natural wind enters the charging pile body 1 to cool it. This way is more obvious in cooling effect than air cooling, and compared with water cooling, the cooling liquid tank 302 and the charging pile body 1 are separately arranged to prevent liquid leakage into the charging pile body 1, and the complexity of pipeline layout is also avoided.

[0029] The two chambers in the cooling liquid tank 302 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 303, and temperature sensors are arranged in the first chamber and the second chamber. When the temperature sensor in any chamber in the working state detects that the temperature reaches the preset value, the preset value indicates that the cooling liquid temperature rises to reduce the pre-cooling effect of the natural wind. 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 in the first chamber reaches the preset value, the three-way valve pipe 303 injects the natural wind into the second chamber, and the first chamber is in a cooling state at this time. The cooling liquid in the second chamber continues to cool and pre-cool the natural wind, and the first chamber and the second chamber are separated by a partition plate such as a ceramic plate which has a heat insulation effect to prevent heat transfer.

[0030] Based on the above description, by detecting the cooling temperature in the first chamber and the second chamber in real time, when the temperature in any chamber in the working state 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 circulating switching, the temperature rise of the cooling liquid in a single chamber is avoided to reduce the cooling effect on the inside of the charging pile body 1, so that the external natural wind can always remain in a low-temperature state to cool the charging pile body 1.

[0031] As Figures 1-5As shown, the side of the charging pile body 1 is provided with an exhaust assembly 4, which includes a heat dissipation hole 401 and a gas collecting cover 402, and the side of the charging pile body 1 is covered with the gas collecting cover 402 outside the heat dissipation hole 401, and the exhaust assembly 4 further includes an exhaust pipe 403, and the surface of the gas collecting cover 402 is connected with the exhaust pipe 403, and the end of the exhaust pipe 403 extends to the outside of the vehicle through the window.

[0032] The specific operation is as follows: the low-temperature natural wind entering the inside of the charging pile body 1 is heated and then passes through the heat dissipation hole 401 and enters the inside of the exhaust pipe 403 along the gas collecting cover 402, and the exhaust pipe 403 is a soft pipe, and the end thereof is placed in the parking space through the window, thereby facilitating the direct placement of the high-temperature natural wind after heat absorption outside the vehicle, so as to prevent the heat from directly accumulating in the vehicle.

[0033] As shown, Figures 1-5 The side of the charging pile body 1 is provided with a winding assembly 5 on one side of the gas collecting cover 402, and the winding assembly 5 includes a winding turntable 501 and a charging line 502, and the surface of the winding turntable 501 is wound with the charging line 502, and the winding assembly 5 further includes a charging plug 503, and 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, the charging plug 503 is manually held and pulled out, at this time, the winding turntable 501 is rotated under the action of tension to make the charging line 502 be released, and after the length of the charging line 502 is released is appropriate, the charging plug 503 is manually inserted into the charging port of the new energy vehicle, thereby charging the new energy vehicle, and after the charging is completed, the charging plug 503 is pulled out, and then the winding turntable 501 is reversely rotated to wind the excess part of the charging line 502, so that the charging line 502 is neatly stored, and the charging line 502 and the charging plug 503 are prevented from being shaken and collided during vehicle driving due to random storage and placement.

[0035] In summary, the mobile energy storage charging pile is used, first, when performing rescue charging for a new energy vehicle, the charging plug 503 is manually held and pulled out, at this time, the winding turntable 501 is rotated under the action of tension to make the charging line 502 be released, and after the length of the charging line 502 is released is appropriate, the charging plug 503 is manually inserted into the charging port of the new energy vehicle, thereby charging the new energy vehicle, and after the charging is completed, the charging plug 503 is pulled out, and then the winding turntable 501 is reversely rotated to wind the excess part of the charging line 502;

[0036] When charging, the natural wind outside drives the wind vane 308 to rotate the carrier plate 307 to carry the air inlet 309 to rotate, so that the opening of the air inlet 309 is always upwind, 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 three-way valve pipe 303 at the bottom to enter the first chamber in the cooling liquid tank 302, and the cooling liquid in the first chamber is used to pre-cool the natural wind outside. The pre-cooled natural wind passes through the pipeline and the activated carbon in the drying tank 301 to dehumidify, and the dehumidified natural wind enters the charging pile body 1 through the air inlet pipe 2 to cool it.

[0037] The air inlet pipe 2 is provided with a wind speed sensor, based on the flow speed of the natural wind outside, the motor output power is adjusted to adjust the rotating speed of the fan 304 through the control program, when only the natural wind passes through the air inlet pipe 2, if the wind speed reaches the preset value, the fan 304 stops rotating, the preset value is set according to the actual situation, which can 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 rotating 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 rotating speed of the fan 304, so that the fan 304 actively extracts the outside air to make up the wind power.

[0038] The two chambers in the cooling liquid 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 three-way valve pipe 303 at the bottom, and the temperature sensors are arranged in the first chamber and the second chamber, when the temperature sensor in any chamber in working state detects that the temperature reaches the preset value, the preset value indicates that the cooling liquid temperature rises to reduce the pre-cooling effect of the natural wind, at this time the exhaust end at both ends of the three-way valve pipe 303 at the bottom is switched on, for example, the temperature in 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 cooling state at this time, and the cooling liquid in the second chamber is used to continue to cool and pre-cool the natural wind.

[0039] The low-temperature natural wind entering the charging pile body 1 absorbs heat, passes through the heat dissipation hole 401 and enters the exhaust pipe 403 inside the air collecting cover 402, the exhaust pipe 403 is a flexible pipe, the end of which passes through the vehicle window and is placed in the parking space, so as to directly exhaust the high-temperature natural wind after heat absorption outside the vehicle, thereby preventing the heat from directly accumulating in the vehicle.
