Description

Technical Field

[0001] The invention relates to the technical field of hydrogen filling devices, and in particular to a hydrogen filling system with an automatic grounding function. Background Art

[0002] (Fuel cell) Hydrogen vehicles must be grounded before refueling to prevent the hydrogen vehicles from accumulating charge and generating static electricity. Although the energy generated by static electricity is small (generally not more than millijoules), it may generate a high static voltage. Sparks during static discharge may cause the hydrogen in the hydrogen refueling station to explode, causing an accident. At present, hydrogen vehicles at hydrogen refueling stations are grounded manually when refueling, that is, the grounding clamp connected to the grounding wire is manually clamped on the grounding block of the hydrogen vehicle (the grounding block is usually set on the chassis of the hydrogen vehicle. Some vehicles do not have a special grounding block. In this case, the grounding clamp can be clamped on the metal part of the vehicle floor). Manual grounding of hydrogen vehicles will bring inconvenience to the hydrogen refueling staff, and the staff are prone to forget the grounding operation, which will cause great safety risks and reduce the hydrogen refueling efficiency.

DETAILED DESCRIPTION

[0016] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0017] Please refer to Figures 1 to 5A hydrogenation system with automatic grounding function of the present invention includes a hydrogenation machine 1, a grounding rail 3 and a mobile vehicle 4.

[0018] The hydrogenation machine 1 is arranged beside a hydrogenation parking space 2 for parking a hydrogenation vehicle 5 (the hydrogenation parking space 2 is arranged on the ground), and a hydrogenation connector 11 for connecting the hydrogen energy vehicle 5 is arranged on the hydrogenation machine 1 .

[0019] A downwardly recessed mounting groove 21 is provided in the middle of the hydrogenation parking space 2, and the grounding rail 3 is fixed in the mounting groove 21. The grounding rail 3 includes a longitudinal rail and two transverse rails arranged at the ends of the longitudinal rail, and the two transverse rails are connected as a whole at the ends of the longitudinal rail through an arc transition. The grounding rail 3 is an I-shaped rail.

[0020] A slot is provided at the bottom of the mobile cart 4, and the slot is stuck on the grounding guide rail 3, so that the mobile cart 4 can be movably supported on the grounding guide rail 3. A plurality of moving rollers 45 are also provided in the slot. The mobile cart 4 is provided with a driving motor (the driving motor is not drawn in the figure) for driving the moving rollers 45 to rotate, and the driving motor is used to drive the mobile cart 4 to slide along the grounding guide rail 3.

[0021] A grounding manipulator 43, a receiving slot 42 and a camera 41 are provided on the top of the mobile cart 4. The grounding manipulator 43 is a double-section manipulator. The grounding manipulator 43 is arranged above the mobile cart 4 and is received in the receiving slot 42 in a folded manner. A grounding clamp 44 that can be automatically opened and clamped is provided at the end of the grounding manipulator 43. The camera 41 is used to obtain an image of a grounding block on the chassis of the hydrogen-energy car 5, obtain the position information of the grounding block by image recognition, and send the position information to the grounding manipulator 43. The grounding manipulator 43 is used to control the mobile cart 4 to move below the grounding block, and move the grounding clamp 44 to the grounding block so that the grounding clamp 44 clamps the grounding block.

[0022] The grounding rail 3 is made of a conductive material, and a plurality of grounding pins 31 are arranged below the grounding rail 3. All the grounding pins 31 pass through the concrete foundation below the hydrogenation parking space 2 and are inserted into the soil below the hydrogenation parking space 2. The upper ends of the grounding pins 31 are connected to the grounding rail 3, so that the entire grounding rail 3 is in a grounded state. Two conductive graphite blocks 46 are also arranged in the card slot of the mobile trolley 4. The two graphite blocks 46 electrically connect the entire mobile trolley 4 and the grounding manipulator 43 arranged on the mobile trolley 4 to the grounding rail 3. When the grounding clamp 44 at the end of the grounding manipulator 43 clamps the grounding block on the hydrogen energy car 5, the grounding block is electrically connected to the grounding rail 3, so that the hydrogen energy car 5 is in a grounded state.

[0023] Furthermore, the hydrogen filling machine 1 is provided with a first communication module and an alarm, and the grounding manipulator 43 is provided with a second communication module that can communicate with the first communication module. The first communication module can send a grounding signal to the second communication module after the hydrogen filling machine 1 is connected to the hydrogen-powered vehicle 5, and the first communication module can send a hydrogenation completion signal to the second communication module after the hydrogenation is completed. The second communication module is used to send a grounding completion signal to the first communication module after the grounding manipulator 43 completes the grounding of the hydrogen-powered vehicle.

[0024] The working process of the hydrogenation system with automatic grounding function of the present invention is as follows: the hydrogen-powered vehicle 5 to be hydrogenated moves to the hydrogenation parking space 2; the staff connects the hydrogenation connector 11 to the hydrogen-powered vehicle 5; the hydrogenation machine 1 sends a grounding signal to the grounding manipulator 43, the grounding manipulator 43 obtains the position information of the grounding block through the camera 41, controls the moving vehicle 4 to move below the grounding block, and controls the grounding clamp 44 to move to the grounding block, so that the grounding clamp 44 clamps the grounding block, thereby grounding the hydrogen-powered vehicle 5; the grounding of the hydrogen-powered vehicle 5 is completed. After that, the grounding manipulator 43 sends a grounding completion signal to the hydrogen filling machine 1; the staff presses the hydrogen filling button on the hydrogen filling machine 1, and the hydrogen filling machine 1 starts to fill the hydrogen car 5 with hydrogen; after the hydrogen car 5 is filled with hydrogen, the staff removes the hydrogen filling connector 11 from the hydrogen car 5; after the hydrogen filling machine 1 senses that the hydrogen filling connector 11 is disconnected from the hydrogen car 5, the hydrogen filling machine 1 sends a hydrogen filling completion signal to the grounding manipulator 43; the grounding manipulator 43 controls the grounding clamp 44 to separate from the hydrogen car 5, and fold it into the receiving tank 42.

[0025] In the above process, if the grounding manipulator 43 has not completed the grounding process of the hydrogen car (that is, the hydrogen filling machine 1 has not received the grounding completion signal), the staff presses the button. At this time, the hydrogen filling machine 1 cannot add hydrogen to the hydrogen car 5. At the same time, the alarm on the hydrogen filling machine 1 sounds an alarm to remind the staff that the hydrogen car 5 is not grounded.
