Description

Technical Field

[0001] The present invention relates to the technical field of fuel cell storage device applications, and in particular to an intelligent hydrogen storage device for a hydrogen fuel cell. Background Art

[0002] With the development of economy, the demand for traditional energy such as coal, oil and natural gas is increasing day by day. However, these traditional energy sources are generally non-renewable resources, and the consumption products are generally polluting. At present, many countries are looking for and researching new alternative energy sources, such as solar energy, wind energy, hydrogen energy, nuclear energy, etc. Hydrogen energy has become one of the most ideal and long-term energy sources with its advantages of high energy conversion rate, wide sources and pollution-free products. At present, there are generally two ways to use hydrogen: one is combustion, which converts hydrogen energy into heat energy or electrical energy; the other is to use advanced power generation devices (such as fuel cells) to convert hydrogen energy into electrical energy. Fuel cells are an important way to apply hydrogen energy. Usually, hydrogen stored in hydrogen storage devices is used as fuel. For gaseous hydrogen, there are generally two common storage methods, namely high-pressure cylinder hydrogen storage and metal hydride solid hydrogen storage. Metal hydride solid hydrogen storage generally places metal hydride hydrogen storage materials in hydrogen storage containers. It is a solid-state hydrogen storage technology. Compared with other methods, it has the advantages of good safety, high hydrogen storage density and high hydrogen storage purity. However, the use of metal hydride solid hydrogen storage has the following disadvantages: when hydrogen is filled into the hydrogen storage device, the metal hydride hydrogen storage material will release a large amount of heat while absorbing hydrogen. When the metal hydride hydrogen storage material releases hydrogen to the outside, it needs to absorb a certain amount of heat. If there is no effective heat transfer device, this alternation of cold and hot will easily cause the hydrogen storage device to deform or rupture on the one hand, and will also seriously affect the speed and efficiency of hydrogen filling and discharging of the hydrogen storage device on the other hand, thereby affecting the stability of the fuel cell. Therefore, the hydrogen storage device should be provided with a necessary radiator. At present, the hydrogen storage container is generally used to contact with the radiator for heat exchange, so as to achieve the purpose of heat dissipation or heat absorption. The existing hydrogen storage device is provided with a radiator (i.e., a heat sink) outside the hydrogen storage device, which has a certain heat dissipation effect, but the radiator is only in contact with the outer wall of the hydrogen storage container, and the hydrogen storage material cannot quickly exchange heat with the radiator, which may cause the hydrogen storage device to deform or rupture, and to a certain extent also reduces the speed and efficiency of hydrogen filling and discharging, thereby affecting the stability of the fuel cell.

[0040] The driving mechanism is used to output power to the air cooling mechanism, the dehumidification mechanism and the cleaning mechanism. A transmission mechanism is provided between the driving mechanism and the air cooling mechanism, the dehumidification mechanism and the cleaning mechanism. The driving mechanism includes a third fixed plate fixedly connected to the inside of the shell 1, and a driving motor 18 is fixedly connected to the third fixed plate. The output shaft of the driving motor 18 is fixedly connected to the first pulley 19.

[0041] In the present invention, the transmission mechanism includes a second pulley 20 fixedly connected to one end of the worm 17, the other end of the second connecting rod 7 is fixedly connected to the third pulley 21, and one end of the linkage rod 4 is fixedly connected to the fourth pulley 22. The fourth pulley 22 is respectively connected to the first pulley 19, the second pulley 20 and the third pulley 21 by the same belt 23. The start of the drive motor 18 drives the rotation of the first pulley 19, and at the same time drives the second pulley 20, the third pulley 22 and the third pulley 21 to rotate synchronously through the belt.

[0042] In the present invention, the tops of multiple solid-state hydrogen storage container tanks 28 are respectively fixedly connected with first connecting pipes 27, the same second connecting pipe is fixedly connected between the multiple first connecting pipes 27, and the two ends of the second connecting pipe are respectively fixedly connected with a hydrogen filling valve 25 and a hydrogen release valve 24. The hydrogen filling process is performed by opening the hydrogen filling valve 25, and the hydrogen release process is performed through the hydrogen release valve 24.

[0043] Working principle: During use, hydrogen is filled into the tank by opening the hydrogen filling valve 25. High temperature is generated during tank filling. At this time, the coolant storage tank 10 starts to operate to attract the coolant into the condenser 11. The coolant in the condenser 11 cools the solid hydrogen storage container tank 28, and at the same time, the cooling transfer is performed through the heat sink 12.

[0044] At the same time, the start of the driving motor 18 drives the first pulley 19 to rotate, and the rotation of the first pulley 19 drives the second pulley 20, the third pulley 21 and the fourth pulley 22 to rotate synchronously through the belt 23, and the rotation of the fourth pulley 22 drives the rotation of the connecting rod 4, and the rotation of the connecting rod 4 drives the two second bevel gears 6 to rotate synchronously, and the rotation of the two second bevel gears 6 drives the two first bevel gears 5 to rotate, and the rotation of the two first bevel gears 5 drives the synchronous rotation of the first connecting rod 2, and the rotation of the two first connecting rods 2 drives the rotation of the two first fan blades 3 respectively, and the heat sink 12 inside the shell 1 is cooled by air through the rotation of the first fan blades 3, and the cold air generated by the condenser 11 is blown, so as to achieve more effective cooling and cooling.

[0045] The rotation of the second pulley 20 drives the rotation of the worm 17, and the rotation of the worm 17 drives the worm wheel 16 to rotate. The rotation of the worm wheel 16 drives the rotation of the reciprocating screw 13, and the rotation of the reciprocating screw 13 drives the movable plate 14 to move smoothly along the trapezoidal slider 17 through the trapezoidal slide groove. When the movable plate 14 moves, the cleaning plate 15 is synchronously driven to reciprocate. The top of the heat sink 12 located inside the shell 1 is cleaned by the reciprocating movement of the cleaning plate 15, and the cleaned floating dust falls into the storage tank. The floating dust can be cleaned later by opening the warehouse door 26. At the same time, the rotation of the third pulley 21 drives the rotation of the second connecting rod 7, and the rotation of the second connecting rod 7 drives the synchronous rotation of the second fan blade 8. Due to the rotation direction of the second fan blade 8, a negative pressure is generated inside the shell 1, thereby attracting and discharging the moisture and high temperature inside the shell 1 to the outside of the shell 1.

[0046] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
