Description

Technical Field

[0001] The present invention relates to the technical field of automobile DC charging piles, and in particular to an automobile DC charging pile with a hydrogen energy storage device and a hydrogen energy generator. Background Art

[0002] Hydrogen energy storage usually refers to using electricity to electrolyze water into hydrogen and oxygen, and then storing the hydrogen. When energy is needed, the stored hydrogen can be reacted with oxygen in a hydrogen generator to produce electricity and water. Hydrogen energy storage technology and hydrogen generators can be combined to achieve energy storage and utilization. This method can use hydrogen to efficiently generate electricity. At the same time, the main emission produced is water. Therefore, it is a clean energy generation method. Using hydrogen energy storage with a hydrogen generator to generate electricity at a car DC charging station can save energy.

[0003] In the prior art, such as the Chinese publication number CN113665394B, the present invention provides an intelligent DC double-gun orderly charging pile, including a charging pile body, the charging pile body including a shell, a charging gun, a bottom plate and a winding shaft, an interactive panel is arranged at the front end of the shell, a baffle and a charging gun are installed on both sides of the shell, the rear end of the charging gun is connected with an output wire through a card block, exhaust pipes are installed on both sides of the charging gun, a suction cup is installed at one end of the exhaust pipe, a magnet 2 is arranged at the rear end of the suction cup, a handle is installed at the bottom end of the charging gun, a hook is installed at the bottom end of the handle, a wire hole is opened at the bottom end of the baffle, a magnet 1 is installed on both sides of the wire hole, a roller is installed at the bottom end of the wire hole, and a motor is installed on one side of the interior of the shell. The intelligent DC double-gun orderly charging pile is simple and convenient to use, can automatically recycle the charging gun, has a higher utilization rate, a firm connection, is more intelligent, and has the function of mobile use.

[0004] When using a hydrogen generator to generate electricity for a charging pile, electricity and water will be generated. Most of the water is directly discharged without being utilized, reducing the energy utilization rate. When the charging pile charges the car, the charging head is inserted into the car's charging port for charging. The charging pile is generally used outdoors. When the charging head is not in use, it is just hung on the surface of the charging pile. On rainy days, rainwater can easily enter the charging head and soak it, which can easily lead to danger during charging. Moreover, the operation and maintenance of the charging pile is a long process. During this process, there are various dangerous factors at the charging site. The most common dangerous factor is that the charging pile is prone to collision at the charging site and can be knocked down easily. Since the charging pile uses a high-voltage line, once the relevant power cable or the insulation system of the charging pile fails, it is easy to break down. Summary of the invention

[0005] The present invention provides a DC charging pile for automobiles with hydrogen energy storage and a hydrogen generator. When the hydrogen generator burns to generate electricity, the water generated is utilized to dissipate heat inside the charging pile body, so as to avoid excessive temperature inside the charging pile body and spontaneous combustion, thereby improving resource utilization. The present invention can prevent rainwater from entering the two charging ports and soaking them on rainy days, thereby reducing the risk of charging electric vehicles. When the charging pile is hit, the charging pile body can be prevented from being knocked down, and failures of related power cables or insulation systems inside the charging pile body can be avoided, thereby improving the safety performance of the charging pile.

[0021] Compared with the prior art, the advantages and positive effects of the present invention are:

[0022] 1. When the present invention needs to utilize the water generated by the combustion and power generation of the hydrogen generator, the hydrogen inside the hydrogen storage tank for combustion and power generation passes through the air guide pipe to the inside of the hydrogen generator, and the fuel cell inside the hydrogen generator uses hydrogen as fuel to generate electricity through chemical reactions. At the same time, the generated water is discharged to the inside of the cooling box through the connecting pipe. The cooling box cools the discharged water. At this time, the switch of the water pump is turned on, and the water inlet of the water pump generates suction. The water cooled by the cooling box passes through its water outlet end to the inside of the disc pipe. The heat generated by the work inside the charging pile body will touch the outer surface of the disc pipe. The inside of the disc pipe contains cooled water, so that the heat is absorbed. Further, under the action of the water pump, the water is discharged to the inside of the water storage tank through the first water pipe for storage, so that the water generated by the combustion and power generation of the hydrogen generator can be utilized. At the same time, with the cooperation of the two heat sinks, when the internal parts of the charging pile body are working, the inside of the charging pile body is dissipated. In this way, the temperature inside the charging pile body is prevented from being too high and spontaneous combustion occurs, especially in hot summer. At the same time, the water generated by combustion and power generation is also utilized to improve resource utilization.

[0023] 2. On rainy days, the two waterproof frames can prevent rain from contacting the charging ends of the two charging ports. At this time, turn on the external power supply of the drive motor. The two L-shaped rods have a mounting function for the drive motor. The rotating rod can rotate due to the bearing, so that the output shaft of the drive motor drives the rotating rod to rotate, and further rotates the bevel gear. Because of the meshing connection, when the bevel gear rotates, it drives the two bevel gears to rotate. The two transmission rods can rotate due to the bearing. The two plug plates and two ring sleeves support and fix the two transmission rods respectively, and the partition allows them to be installed inside the base. At this time, the two transmission rods rotate, further causing the two fan blades to rotate. When the two fan blades rotate, they will drive the circulation of air and further blow the rainwater. When there is a problem with the parts on the partition and they need to be replaced, turn the threaded nails on the baffle to remove it and repair it. The two protective nets can prevent dust from entering the interior of the charging pile body, and at the same time isolate people from the possibility of contact with the two fan blades. On rainy days, the two rotating fan blades can blow rainwater, further preventing rainwater from contacting the charging end of the two charging ports, preventing rainwater from entering the two charging ports and soaking them, thereby reducing the risk of charging electric vehicles.

[0024] 3. When the charging pile body is hit, the two first telescopic rods can rotate around the two horizontal axes. At this time, one side of the charging pile body is subjected to force, and the two first telescopic rods can slide on the outer surfaces of the two second telescopic rods respectively, so that one of the first telescopic rods pushes one of the springs. Since one side of the two springs is respectively on one side of the two circular plates, the two springs will generate a reverse force when the two sides of the charging pile body are hit, further pushing one of the first telescopic rods in the opposite direction to prevent the charging pile body from tipping over. The two rubber sheets are connected to the second telescopic rod through two pressure plates. The two rubber sheets increase the friction between the two pressure plates and the ground. Therefore, when the charging pile body is hit, the two rubber sheets and the two springs can prevent the charging pile body from being knocked over, avoid failures of related power cables or insulation systems inside the charging pile body, and improve the safety performance of the charging pile.

[0041] When the water generated by the combustion of the hydrogen generator 212 is used, the hydrogen in the hydrogen storage tank 205 comes to the inside of the hydrogen generator 212 through the air guide pipe 207, and the fuel cell inside the hydrogen generator 212 uses hydrogen as fuel to generate electricity through chemical reactions.

The two L-shaped rods 305 respectively have a mounting function for the driving motor 306. The rotating rod 307 can rotate due to the bearing. When the external power supply of the driving motor 306 is turned on, the output shaft of the driving motor 306 drives the rotating rod 307 to rotate.

[0045] See also Figure 7 , Figure 8 , Fig.10 and Fig.11 In one embodiment, a ring sleeve 312 is fixedly provided on one side of the two plug plates 311. The two ring sleeves 312 are respectively connected to the outer surfaces of the two transmission rods 310 through bearings. The two plug plates 311 and the two ring sleeves 312 respectively support and fix the two transmission rods 310. The two transmission rods 310 can rotate due to the bearing effect of the two ring sleeves 312.

[0046] See also Figure 8 and Fig.11 In one embodiment, fan blades 313 are installed on the opposite sides of the two transmission rods 310, and a protective net 303 is fixedly set on the side of the charging pile body 2 close to the two fan blades 313.

[0047] See also Figure 1 , Figure 2 and Fig. 9 In one embodiment, mounting blocks 4 are fixedly provided on both sides of the base 1 by screws, and horizontal shafts 401 are fixedly provided on the inner walls of the two mounting blocks 4.

The two first telescopic rods 402 can slide on the outer surface of the two second telescopic rods 403 respectively, so that one of the first telescopic rods 402 pushes one of the springs 404. Since one side of the two springs 404 is respectively on one side of the two circular plates 407, when the two springs 404 are collided on both sides of the charging pile body 2, a reverse force will be generated, further pushing one of the first telescopic rods 402 in the reverse direction.

[0049] See also Figure 1 In one embodiment, a pressure plate 405 is fixedly provided on one side of the two second telescopic rods 403, and a rubber sheet 406 is fixedly provided on one side of the two pressure plates 405. The two rubber sheets 406 are connected to the second telescopic rods 403 through the two pressure plates 405, and the two rubber sheets 406 increase the friction between the two pressure plates 405 and the ground.

[0050] Working principle: When it is necessary to utilize the water generated by the hydrogen generator 212, the base 1 supports the entire charging pile. The hydrogen storage tank 205 is filled with hydrogen, and the hydrogen storage tank 205 is installed on the charging pile body 2 through the fixing frame 204 by rotating a plurality of screws. When burning to generate electricity, the hydrogen inside the hydrogen storage tank 205 passes through the air guide pipe 207 to the inside of the hydrogen generator 212, and the fuel cell inside the hydrogen generator 212 uses hydrogen as fuel to generate electricity through chemical reactions. At the same time, the generated water is discharged to the inside of the cooling box 210 through the connecting pipe 211. The cooling box 210 cools the discharged water. At this time, the switch of the water pump 203 is turned on, and the water inlet of the water pump 203 generates suction, which further cools the box 21 The cooled water comes to the inside of the coil-shaped pipe 209 through its water outlet end. The heat generated by the working inside the charging pile body 2 will touch the outer surface of the coil-shaped pipe 209. The inside of the coil-shaped pipe 209 contains cooled water, so the heat is absorbed. Further, under the action of the water pump 203, the water is discharged to the inside of the water storage tank 201 through the first water pipe 202 for storage, so that the water generated by the combustion and power generation of the hydrogen energy generator 212 can be utilized. At the same time, with the cooperation of the two heat sinks 208, when the internal parts of the charging pile body 2 are working, the inside of the charging pile body 2 is cooled, so that the temperature inside the charging pile body 2 is prevented from being too high and spontaneous combustion occurs, especially in hot summer, and the water generated by combustion and power generation can also be utilized;

[0051] On rainy days, the two waterproof frames 3 prevent rainwater from contacting the charging ends of the two charging ports 301. At this time, the external power supply of the drive motor 306 is turned on, and the two L-shaped rods 305 respectively have a mounting function for the drive motor 306. The rotating rod 307 can rotate due to the bearing, so that the output shaft of the drive motor 306 drives the rotating rod 307 to rotate, and further rotates the bevel gear 308. Because of the meshing connection, when the bevel gear 308 rotates, it drives the two bevel gears 309 to rotate. The two transmission rods 310 can rotate due to the bearing. The two plug plates 311 and the two ring sleeves 312 respectively support and fix the two transmission rods 310, and the partition 304 allows it to be installed. Inside the base 1, the two transmission rods 310 rotate at this time, further causing the two fan blades 313 to rotate. When the two fan blades 313 rotate, the air circulation is driven, and the rainwater is further blown. When there is a problem with the parts on the partition 304 and they need to be replaced, the threaded nails on the rotating baffle 302 are removed to repair them. The two protective nets 303 can prevent dust from entering the interior of the charging pile body 2, and also isolate people from the possibility of contact with the two fan blades 313. On rainy days, the two rotating fan blades 313 can blow rainwater, further preventing rainwater from contacting the charging end of the two charging ports 301, preventing rainwater from entering the two charging ports 301 and soaking them, thereby reducing the risk of charging electric vehicles;

[0052] When the charging pile body 2 is hit, the two first telescopic rods 402 can rotate around the two transverse axes 401. At this time, one side of the charging pile body 2 is subjected to force, and the two first telescopic rods 402 can slide on the outer surfaces of the two second telescopic rods 403 respectively, so that one of the first telescopic rods 402 pushes one of the springs 404. Since one side of the two springs 404 is respectively on one side of the two circular plates 407, the two springs 404 will generate a reverse force when the two sides of the charging pile body 2 are hit, further pushing one of the first telescopic rods 402 in the opposite direction to prevent the charging pile body 2 from tipping over. The two rubber sheets 406 are connected to the second telescopic rod 403 through the two pressure plates 405. The two rubber sheets 406 increase the friction between the two pressure plates 405 and the ground. Therefore, when the charging pile body 2 is hit, the two rubber sheets 406 and the two springs 404 can prevent the charging pile body 2 from being knocked over, avoid failure of related power cables or insulation systems inside the charging pile body 2, and improve the safety performance of the charging pile.
