Description

Technical Field

[0001] This utility model relates to the field of energy storage cabinet technology, specifically a hydrogen energy storage cabinet with a drainage structure. Background Technology

[0002] Hydrogen energy, the chemical energy released from the chemical reaction of hydrogen and oxygen, is a secondary clean energy source. It is being rapidly developed and utilized against the backdrop of carbon peaking and carbon neutrality. In daily life, hydrogen energy is often stored using energy storage cabinets as energy storage units.

[0003] Although the device has many beneficial effects in the existing technology, the following problems still exist: the hydrogen has a low density and tends to accumulate at the top of the cabinet. The traditional top-closed design cannot directionally discharge the hydrogen, and the bottom drain may become a hydrogen leakage channel. Secondly, the condensate produced by the hydrogen energy system's electrolyzer, compressor and other components tends to stagnate at the bottom of the equipment. The existing water trays are mostly flat structures, which cannot effectively guide the flow and significantly increase the risk of short circuits in electronic components. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] 1. Technical problems to be solved:

[0006] To address the aforementioned problems of hydrogen inability to be discharged and ineffective flow diversion, this utility model is proposed.

[0007] Therefore, the purpose of this utility model is to provide an energy storage cabinet with a drainage structure. This energy storage cabinet with a drainage structure is equipped with a pneumatically driven flap valve, a counterweight, and a limiting plate. When hydrogen accumulates and reaches a certain pressure, the hydrogen rises and triggers the valve to open. Combined with the gas rectification path formed by the louvers and the air duct, the hydrogen is discharged in a directional manner. At the same time, a double-layer perforated support plate is provided to facilitate the dripping of condensate from the conversion layer and the energy storage layer. The condensate is quickly collected by the inclined water collection trays one and two and discharged through the drain pipe. The bottom of the drain pipe is equipped with a double-layer sealing sleeve to prevent leakage at the joint between the drain pipe and the frame.

[0032] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0033] This utility model provides an overall structural diagram of an embodiment of an energy storage cabinet with a drainage structure, including:

[0034] Please see Figures 1-5 This embodiment of an energy storage cabinet with a drainage structure includes a cabinet body 100 including a frame 110. A top cover 120 is fixedly connected to the top of the frame 110 by bolts. An exhaust assembly 200 is provided on the top of the top cover 120. The exhaust assembly 200 includes louvers 230. A fixing frame 131 is welded to the inner wall of the frame 110. A control layer 130 is provided on the top of the fixing frame 131. A conversion layer 140 and an energy storage layer 150 are provided at the bottom of the fixing frame 131. A drainage assembly 300 is provided at the bottom of the inner cavity of the frame 110. The drainage assembly 300 includes a drain pipe 330.

[0035] It is worth noting that, for the electrical energy storage control of the energy storage cabinet, specifically, the control layer 130 includes a control unit, the side wall of which is electrically connected to a power distribution module, and the control unit is electrically connected to the conversion layer 140 and the energy storage layer 150. The conversion layer 140 includes a fuel cell stack and a converter, the side wall of which is electrically connected to a liquid cooling system, and the energy storage layer 150 includes six hydrogen storage cylinders.

[0036] Next, in order for the exhaust assembly 200 to discharge hydrogen, specifically, the exhaust assembly 200 includes a valve 210, the top of which is fixedly connected to an air passage 220 by screws. Multiple guide vanes are welded inside the air passage 220. The guide vanes have a wave-shaped structure, which accelerates the airflow speed and improves exhaust efficiency. The top of the air passage 220 is fixedly connected to a louver 230 by screws. The louver 230 has a blade tilt angle of 55 degrees, forming a one-way gas channel. The hydrogen is preferentially discharged by the air density difference. The top of the louver 230 is fixedly connected to an insect screen 240 by screws.

[0037] Meanwhile, in order to collect and discharge condensate in the drainage assembly 300, specifically, the drainage assembly 300 includes an upper support plate 310, a water collection tray 311 fixedly connected to the bottom of the upper support plate 310 by bolts, a drain pipe 330 inserted into the bottom side wall of the water collection tray 311, a connecting pipe 331 inserted into the outer circumference of the bottom of the drain pipe 330, a water collection tray 321 sleeved on the outer circumference of the connecting pipe 331, a lower support plate 320 fixedly connected to the top of the water collection tray 321 by bolts, a sealing sleeve 332 sleeved on the outer circumference of the bottom of the drain pipe 330, and a sealing sleeve 333 sleeved through the frame 110 on the outer circumference of the bottom of the drain pipe 330. The sealing sleeves 332 and 333 effectively improve the sealing between the drain pipe 330 and the frame 110, preventing hydrogen from leaking from the gaps next to the drain pipe 330.

[0038] Furthermore, to facilitate the use of the energy storage cabinet, specifically, the side wall of the frame 110 has multiple square slots, one of which is connected to the main door 111 via a hinge. The side wall of the main door 111 has an inspection window, which allows users to check the working status of the energy storage cabinet. One of the square slots is connected to the auxiliary door 112 via a hinge, which allows users to maintain the energy storage cabinet. The fixing frame 131 and the top cover 120, and the upper support plate 310 are fixedly connected to multiple support columns 132 via screws. The lower support plate 320, the upper support plate 310, and the frame 110 are also fixedly connected to multiple support columns 132 via screws.

[0039] It is worth noting that, in order to enable one-way exhaust of the air valve 210, specifically, the air valve 210 includes a mounting base 211. The top of the mounting base 211 has a circular through hole, and a sealing ring 214 is embedded in the inner wall of the circular through hole to improve the air tightness of the air valve 210. A limit plate 215 is welded to the inner wall of the mounting base 211 to limit the rotation direction of the rotating plate 213. A rotating shaft 212 is inserted into the side wall of the mounting base 211. The rotating plate 213 is sleeved on the outer wall of the rotating shaft 212. The sealing ring 214 is fitted to the outer wall of the rotating plate 213. A counterweight 216 is welded to the top of the rotating plate 213 to facilitate the reset of the rotating plate 213.

[0040] Finally, to facilitate the collection of condensate, the top of the upper support plate 310 and the lower support plate 320 are provided with multiple drainage holes to facilitate the dripping of condensate into the first water collection tray 311 and the second water collection tray 321. The inclined angle of the first water collection tray 311 is 8 degrees to facilitate the flow of condensate.

[0041] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0042] Combination Figures 1-5 The specific usage process of an energy storage cabinet with a drainage structure according to this embodiment is as follows:

[0043] 1: This energy storage cabinet controls the operation of various electronic components through the control layer 130, the conversion layer 140 is used to convert energy, and the energy storage layer 150 is used to store hydrogen energy. The working status of the energy storage cabinet can be viewed through the main door 111 and the auxiliary door 112, which facilitates maintenance work for users.

[0044] 2: Due to the difference in gas density, hydrogen rises and accumulates at the top of the energy storage cabinet. When the gas pressure reaches a certain level, the rotating plate 213 of the gas valve 210 is rotated under force. At the same time, the limiting plate 215 effectively restricts the rotation direction of the rotating plate 213. Then, the airflow speed is accelerated through the guide plate of the air passage 220 and discharged from the top of the louver 230. When the gas pressure inside the energy storage cabinet drops to a certain level, the rotating plate 213 rotates again under the pressure of the counterweight 216 and tightly adheres to the sealing ring 214 to prevent airflow.

[0045] 3: When the energy storage cabinet is in operation, the condensate from the conversion layer 140 and the energy storage layer 150 drips into the first water collection tray 311 and the second water collection tray 321 respectively through the upper support plate 310 and the lower support plate 320 which have drainage holes. Then it flows out through the drain pipe 330 and the connecting pipe 331, reducing the risk of short circuits in electronic components due to condensate accumulation. At the same time, the sealing sleeves 332 and 333 fitted on the outer circumference of the drain pipe 330 enhance the sealing of the connection between the drain pipe 330 and the frame 110, facilitating the unidirectional discharge of hydrogen from the top exhaust assembly 200.

[0046] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
