Figure 1 Figure 1 Figure 1 Figure 1 Figure 1 Figure 1 Figure 1

[0033] As shown in the figure, the utility model provides a kind of integrated energy equipment for light hydrogen storage, including cabinet 100, and the hydrogen storage module 200, purification module 300, hydrogen production module 400, power module 500 and control module 600 being set in the cabinet 100;The hydrogen storage module 200 is installed in the upper portion of the cabinet 100;The purification module 300, hydrogen production module 400, power module 500 and control module 600 are all arranged in the lower portion of the cabinet 100, and are sequentially arranged from the side of the cabinet 100 to the other side of the cabinet 100. Figures 1-2

[0034] The control module 600 includes energy management device 610 and control mainboard 620, and the energy management device 610 and control mainboard 620 can be close to the front inner side of the cabinet 100 from bottom to top. Specifically, the energy management device 610 is circumscribed by a photoelectric conversion system, for powering each electrical device in the integrated energy equipment for light hydrogen storage, specifically including DC / DC converter and hydrogen production power supply, the DC / DC converter is used to convert the direct current output by the photoelectric conversion system into 24V direct current for use by each electrical device inside the equipment except the hydrogen production device 430;The hydrogen production power supply is used to convert the direct current output by the photoelectric conversion system into 22V direct current for use by the hydrogen production device 430 of the hydrogen production module 400 to electrolyze water to produce hydrogen. The control mainboard 620 is electrically connected with the energy management device 610, for signal control of the power-on and operation of each electrical device in the integrated energy equipment for light hydrogen storage.

[0035] ​​​​​​​​The power module 500 includes an inverter 510, a charging controller 520 and an energy storage battery 530, the inverter 510 is fixedly installed close to the front inner side of the cabinet 100 through a first support 550, and is located between the control module 600 and the hydrogen production module 400. The charging controller 520 is installed on the cabinet 100 through a second support 560, and is located between the inverter 510 and the hydrogen production module 400. The energy storage battery 530 can be a lithium battery, due to the large volume of the energy storage battery 530, it can be placed behind the control module 600 and the inverter 510.

[0036] The input end of the charging controller 520 is externally connected with a photoelectric conversion system, and the output end is electrically connected with the input end of the energy storage battery 530, for converting photoelectric energy into 48V direct current to charge the energy storage battery 530, and can cut off the charging current when the energy storage battery 530 is fully charged, preventing overcharging. The input end of the inverter 510 is connected with the energy storage battery 530, and the output end is connected with external electrical equipment, when the external electrical equipment needs to use electricity, the inverter 510 converts the 48V direct current stored in the energy storage battery 530 into 220V alternating current and outputs.

[0037] Due to the large volume of the energy storage battery 530, and generally the energy storage battery 530 is not fixed in the cabinet 100 for transportation, the energy storage battery 530 can be installed on the use site of the photo-hydrogen storage integrated energy source equipment, and the installation method is only to place it on the bottom of the cabinet 100. Therefore, after the on-site installation is completed, the energy storage battery 530 has a risk of falling in the case of movement or accidental collision of the photo-hydrogen storage integrated energy source equipment, therefore, the first support 550 needs to be designed and improved to prevent the energy storage battery 530 from falling and damaging the devices in the control module 600.

[0038] Specifically, as shown in Figure 3 and Figure 4 The first support 550 includes a fixed part 551 and a supporting part 552, the fixed part 551 is fixed on the cabinet 100, and the inverter 510 is fixedly installed on the rear end face thereof; the supporting part 552 is vertically arranged on the rear end face of the fixed part 551, and is used for preventing the energy storage battery 530 from falling forward.

[0039] Further, the upper and lower ends of the fixed part 551 are formed with bending parts 5511 towards the rear end face, and the fixed part 551 is fixed on the cabinet 100 through the bending parts 5511, so that the first support 550 is close to the front inner side of the cabinet 100.

[0040] Further, in order to reduce weight and ventilate and dissipate heat of the inverter 510, the support part 552 is provided with through holes 5521. As shown in Figure 3 , the through holes 5521 are provided with at least two, and the at least two through holes 5521 can be arranged at equal intervals from top to bottom to ensure uniformity of heat dissipation. As shown in Figure 4 , the through holes 5521 are openings arranged at the rear end of the support part 552, so that the rear end of the support part 552 is toothed, and the weight reduction can be maximized.

[0041] Please refer to Figure 2 , in order to prevent the energy storage battery 530 from tilting backward, a blocking strip 110 can be installed at the bottom of the cabinet 100 close to the back, and the blocking strip 110 is located behind the energy storage battery 530 and is used to prevent the energy storage battery 530 from tilting backward.

[0042] In addition, in order to save installation space, the second support 560 can be installed on the support 410 of the hydrogen production module 400, and is arranged on the upper layer of the support 410 together with the water storage tank 420 of the hydrogen production module 400, and is located between the inverter 510 and the water storage tank 420.

[0043] Specifically, please refer to Figure 5 , the charging controller 520 can be installed on the upper end surface of the second support 560, and the lower end surface thereof is provided with an inclined surface 561 inclined upward and backward, which can avoid the waterway pipeline of the hydrogen production module 400. The lower end surface of the second support 560 extends downwardly at the right side of the lower end surface of the second support 560 to form a fixing plate 562, which is used to be fixedly connected with the support 410.

[0044] In order to facilitate wiring of the power module 500, the upper end surface and the lower end surface of the second support 560 form a receiving cavity 563 therebetween, which is used to facilitate wiring.

[0045] In summary, in the case of sufficient sunlight, the control module 600 converts the direct current output by the external photoelectric conversion system into constant voltage direct current to supply the hydrogen production module 400 for electrolysis of water to produce hydrogen, the hydrogen produced by the hydrogen production module 400 enters the purification module 300 for water removal and purification, and the purified hydrogen enters the hydrogen storage module 200 for storage. When the external hydrogen equipment (such as a hydrogen energy gas appliance) needs hydrogen, the hydrogen storage module 200 supplies hydrogen to the hydrogen equipment. When the hydrogen storage module 200 is insufficient in gas amount and the hydrogen energy gas appliance needs hydrogen, the hydrogen produced by the hydrogen production module 400 can also be directly delivered to the hydrogen energy gas appliance. At the same time, the charging controller 520 of the control module 600 converts the excess direct current output by the external photoelectric conversion system into constant voltage direct current to supply the power module 500 for power storage. When the external power equipment needs power, the energy storage battery 530 supplies power to the power equipment through the inverter 510.

[0046] Further, in order to ensure that hydrogen can still be produced when solar energy is insufficient, an external AC / DC power supply 540 connected to the mains can be added in the power module 500. Specifically, the accommodation cavity 563 is arranged in a multi-layer structure, the lower layer is used for wiring, and the upper layer is used for installing the AC / DC power supply 540. The AC / DC power supply 540 can have two, one is used to convert the external input 220V alternating current into 22V direct current for the hydrogen production device 430, and the output 22V direct current can be converted into 24V direct current by a DC / DC boost circuit for use by the remaining power devices inside the device; the other is used to convert the external input 220V alternating current into 48V direct current for charging the energy storage battery 530.

[0047] Therefore, the utility model effectively overcomes all kinds of shortcomings in prior art and has high industrial utilization value. The above embodiment only exemplarily illustrates the principle and effect of the utility model, and is not used to limit the utility model.
