Description

Technical Field

[0001] The invention relates to the technical field of electrical equipment, and in particular to a mobile power generation device based on a hydrogen cylinder. Background Art

[0002] Hydrogen power generation refers to the use of hydrogen and oxygen combustion to form a hydrogen-oxygen power generation unit.

[0003] The internal combustion engine is equipped with a generator. It does not require a complex steam boiler system, so it is simple, easy to maintain, and quick to start. It can be started and stopped at any time. When the power grid is under low load, it can also absorb excess electricity to electrolyze water to produce hydrogen and oxygen for power generation during peak hours.

[0004] Conventional mobile power generation devices using hydrogen are generally large in size and use large hydrogen cylinders combined with water to form a mixed fuel, which is transported into the fuel cell to power the fuel cell. The entire power generation process does not require any external power supply. However, the hydrogen cylinders used in this type of equipment are large, and the power generation equipment as a whole is also large.

[0016] Preferably, the mounting sleeve and the hexagonal rotating portion are an integrally formed structure.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. By twisting the structure composed of the external thread ring and the mounting cross bar, the connecting sleeve and the push-pull fixing plate are moved in the mounting seat. As the structure composed of the external thread ring and the mounting cross bar rotates, the push-pull fixing plate will contact the end of the hydrogen bottle, and the end of the hydrogen bottle will first contact multiple arc-shaped pressure heads. When the arc-shaped pressure heads are compressed, the end of the compressed swing rod away from the arc-shaped pressure heads is tilted, thereby driving the compressed swing rod and the buffer gasket to apply pressure to the outer wall of the hydrogen bottle, achieving close contact between the compressed swing rod and the end of the hydrogen bottle, so that the movement of the push-pull fixing plate can drive the movement of the hydrogen bottle, allowing the hydrogen bottle to be supported on multiple support machines. When the hydrogen cylinder moves within the structure and the connection effect between the hydrogen cylinder and the push-pull fixing plate needs to be further improved, the pull-out handle can be pulled to apply pressure to the cross pull-out rod, driving the cross pull-out rod and the rubber plug to move under the guidance of the installation guide frame, thereby applying suction to the center position of the end of the hydrogen cylinder, further strengthening the connection effect between the hydrogen cylinder and the push-pull fixing plate. When the hydrogen cylinder is not in use, the external threaded ring and the installation cross bar can be rotated in the opposite direction to take out the hydrogen cylinder, thereby realizing the installation and removal of the hydrogen cylinder, and the operation can be performed in a smoother and more precise manner, reducing the risk of damage to objects during movement and removal.

[0019] 2. When the end of the hydrogen cylinder contacts the semi-circular frame, the end of the hydrogen cylinder applies pressure to the rubber guide wheel and the outer movable seat. The outer movable seat moves on the inner guide seat and applies pressure to the spring at the same time, driving the spring to deform and generate reverse elastic force. The outer movable seat and the rubber guide wheel are acted upon by the elastic force and apply pressure to the side of the hydrogen cylinder to fix and guide the hydrogen cylinder. At the same time, during the movement of the hydrogen cylinder, the rubber guide wheel contacts the side wall of the hydrogen cylinder. The retractable outer movable seat reduces the pressure of the rubber guide wheel on the side wall of the hydrogen cylinder, thereby reducing the friction force applied to the hydrogen cylinder during movement, improving the smoothness of the movement of the hydrogen cylinder, reducing the hindrance of friction, and enabling the hydrogen cylinder to move more easily and quickly. The reduced friction force can prevent the surface of the hydrogen cylinder from being damaged by wear, scratches and the like due to friction.

[0020] 3. The gas nozzle on the end of the hydrogen cylinder is located in the mounting sleeve and contacts the gas pressure nozzle. The gas pressure nozzle applies pressure to the gas core in the gas nozzle, and the hydrogen in the hydrogen cylinder moves along the mounting sleeve, the gas pressure nozzle and the circular mounting seat to realize the hydrogen discharge. By turning to the hexagonal rotating part, the hexagonal rotating part drives the rotating limit part to move in the circular mounting seat. During the rotation of the hexagonal rotating part, the gas pressure nozzle that moves with the hexagonal rotating part thread is driven to move in the hexagonal rotating part under the guidance of the limit guide rod, thereby changing the pressure distance of the gas pressure nozzle on the gas core in the gas nozzle, thereby changing the efficiency of hydrogen discharge from the gas nozzle on the hydrogen cylinder. The exhaust volume can be accurately adjusted according to specific needs, and fine control of system parameters such as pressure and flow rate can be achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] Working principle:

[0049] Step 1: When the equipment needs to be used, the hydrogen cylinder 3 needs to be installed in the mounting base 1. First, pull the movable buckle 10. When the pulling force is greater than the magnetic force adsorbed between the two magnetic blocks 11, pull the movable buckle 10 and the baffle plate 7 apart, and the mounting groove on the mounting base 1 is exposed. At the same time, when the baffle plate 7 is pulled apart, the connecting cloth 8 will also be deformed to adapt to the pulling action of the baffle plate 7. Hold the protective cover 510, rotate the external threaded ring 501 and the mounting cross bar 502, withdraw the external threaded ring 501 and the mounting cross bar 502 from the mounting groove, and then place the hydrogen cylinder 3 into the mounting base 1 along the mounting groove.

[0050] Step 2: When the end of the hydrogen bottle 3 contacts the semi-circular frame 402, the end of the hydrogen bottle 3 applies pressure to the rubber guide wheel 409 and the outer movable seat 407. The outer movable seat 407 moves on the inner guide seat 406 and applies pressure to the spring 408 at the same time, driving the spring 408 to deform and generate a reverse elastic force. The outer movable seat 407 and the rubber guide wheel 409 are acted upon by the elastic force and apply pressure to the side of the hydrogen bottle 3 to fix and guide the hydrogen bottle 3. At the same time, during the movement of the hydrogen bottle 3, the rubber guide wheel 409 contacts the side wall of the hydrogen bottle 3. The outer movable seat 407 is retracted to reduce the pressure of the rubber guide wheel 409 on the side wall of the hydrogen bottle 3, thereby reducing the friction force on the hydrogen bottle 3 during the movement and improving the smoothness of the movement of the hydrogen bottle 3.

[0051] Step 3: Align the external thread ring 501 with the installation groove, install the external thread ring 501 in the installation groove, and at the same time, by twisting the structure composed of the external thread ring 501 and the installation cross bar 502, let the connecting sleeve 503 and the push-pull fixing plate 504 move in the mounting seat 1. As the structure composed of the external thread ring 501 and the installation cross bar 502 rotates, the push-pull fixing plate 504 will contact the end of the hydrogen bottle 3, and the end of the hydrogen bottle 3 will first contact the multiple arc-shaped pressure heads 508. When the arc-shaped pressure heads 508 are pressurized, the end of the pressure swing rod 506 away from the arc-shaped pressure head 508 is tilted, thereby driving the pressure swing rod 506 and the buffer gasket 507 to apply pressure to the outer wall of the hydrogen bottle 3, so as to achieve the tightness of the pressure swing rod 506 and the end of the hydrogen bottle 3. Close contact, so that the movement of the push-pull fixing plate 504 can drive the movement of the hydrogen bottle 3, allowing the hydrogen bottle 3 to move within the multiple support mechanisms 4. When it is necessary to further improve the connection effect between the hydrogen bottle 3 and the push-pull fixing plate 504, the pull-pull handle 514 can be pulled out to allow the pull-pull handle 514 to apply pressure to the cross pull rod 513, thereby driving the cross pull rod 513 and the rubber plug 512 to move under the guidance of the installation guide frame 515, thereby applying suction to the center position of the end of the hydrogen bottle 3, further strengthening the connection effect between the hydrogen bottle 3 and the push-pull fixing plate 504. When the hydrogen bottle 3 is not in use, the external threaded ring 501 and the installation cross bar 502 can also be rotated in the opposite direction to take out the hydrogen bottle 3, thereby realizing the installation and removal of the hydrogen bottle 3.

[0052] Step 4: the gas nozzle on the end of the hydrogen bottle 3 is located in the mounting sleeve 604 and contacts the gas pressure nozzle 605. The gas pressure nozzle 605 applies pressure to the gas core in the gas nozzle, and the hydrogen in the hydrogen bottle 3 moves along the mounting sleeve 604, the gas pressure nozzle 605 and the circular mounting seat 601 to realize the discharge of hydrogen. By turning to the hexagonal rotating part 602, the hexagonal rotating part 602 drives the rotation limit part 603 to move in the circular mounting seat 601. During the rotation of the hexagonal rotating part 602, the gas pressure nozzle 605 that moves with the hexagonal rotating part 602 threadedly moves in the hexagonal rotating part 602 under the guidance of the limit guide rod 607, thereby changing the pressure distance of the gas pressure nozzle 605 on the gas core in the gas nozzle, thereby changing the efficiency of hydrogen discharge from the gas nozzle on the hydrogen bottle 3.
