[0016] Compared with the prior art, the present invention has achieved the following technical effects:

[0017] 1. The multifunctional quick auxiliary installation device suitable for hydrogen storage bottles of the present invention can effectively clamp the horizontally or vertically placed hydrogen storage bottles, and lift and rotate them to place them vertically or horizontally, so as to facilitate placing the hydrogen storage bottles on the support frame, and can also quickly clamp and fix them, thereby greatly improving efficiency.

[0018] 2. The main frame is made of aluminum alloy, which is strong and light. The lifting rod used in the frame is hollow inside and is designed with tooth grooves. It cooperates with the servo motor to realize the vertical movement of the moving plate. There is a protruding cylindrical structure at one end of the load-bearing plate, which is placed in the corresponding circular holes of the bottom rod-left and bottom rod-right. Under the action of the plug and the spring, the horizontal movement of the load-bearing plate is limited, and the moving plate can be taken out more conveniently. The inclined plate is connected to the pin and the load-bearing plate through a connecting piece. The inclined plate can rotate around the connecting piece. After being lowered, the horizontally placed hydrogen storage bottle moves to the load-bearing plate through the inclined plate; for the vertically placed hydrogen storage bottle, the load-bearing plate can be taken out. Provide enough space for the clamping mechanism.

[0019] 3. There are 4 moving wheels placed at the bottom of the main frame. Together with the handle, they can push the auxiliary device to move, greatly improving the flexibility of the device. The moving wheels can be locked to lock the auxiliary device to ensure the stability of the device during the movement of the hydrogen storage bottle.

[0020] 4. The lifting mechanism uses a servo motor, which uses gears to perfectly mesh with the teeth inside the lifting rod, and reduces speed through the gear system to increase the torque. When the lifting rod is fixed, the servo motor starts to drive the moving plate to move in the vertical direction, while ensuring the uniform and stable speed of the lifting process.

[0021] 5. In the rotating mechanism, the rotating part of the rotating button is grooved to prevent slipping. One end is fixed to the moving plate by screws, and the other end is fixed to the rotating plate by screws. The transmission gear set is used to drive the rotating plate to rotate, so that manual fine-tuning can be achieved or motor-driven.

[0022] 6. The clamping mechanism adjusts the clamping position of the hydrogen storage bottle by changing the position of the slider on the rotating plate, so that hydrogen storage bottles of different specifications can be stably clamped. The hydrogen storage bottle is pushed into the clamping mechanism, and the contact button pushes the limit block into the chuck slide rail, contacts the switch at the end of the slide rail, starts the electromagnet, and locks the chuck. When releasing the hydrogen storage bottle, turn off the electromagnet, and under the action of the spring, the limit block returns to the normal position, and the contact button pushes the hydrogen storage bottle out.
