In this embodiment, the hydrogen station 11 provides hydrogen energy through the hydrogen energy supply device 113, the main compressor 111 compresses the hydrogen energy of the hydrogen energy supply device 113 to a certain pressure, and fills the compressed hydrogen energy into the main buffer bottle 112, and a corresponding pressure difference exists between the main buffer bottle 112 and the hydrogen storage bottle of the device to be hydrogenated 114, that is, the hydrogen energy is filled into the device to be hydrogenated 114 through the pressure difference.
The plurality of hydrogenation stations 11 are provided, for example, 5 hydrogenation stations 11 are provided, and the equipment devices in each hydrogenation station 11 are the same, that is, the equipment devices include a main compressor 111, a main buffer bottle 112 and a hydrogen energy supply device 113, and can hydrogenate the equipment 114 to be hydrogenated in a normal state.
In this embodiment, the abnormal state of the hydrogenation station 11 includes that the main compressor 111 fails to work normally, and the corresponding normal state, that is, the main compressor 111 does not fail, and the hydrogenation station 11 can hydrogenate the equipment 114 to be hydrogenated.
In this embodiment, 5 hydrogenation stations form an area, the spare filling device 21 can be moved by the carrying device within the area, when one of the hydrogenation stations 11 is in an abnormal state, the spare filling device 21 can be moved to the hydrogenation station 11 and butted with the hydrogenation station 11 to continue to hydrogenate the equipment 114 to be hydrogenated in the hydrogenation station 11, so as to ensure the normal operation of the hydrogenation station 11.
Referring to fig. 3, fig. 3 provides a schematic illustration of the construction of a ready-to-use filling apparatus.
Wherein, reserve sled dress 21 is an open-type container, reserve buffer bottle 211 sets up in the container, although not shown in the drawing, but still install hydrogen energy source filling pipeline, corresponding circuit etc. on reserve sled dress 21 at least, simultaneously, main buffer bottle 112 also sets up on main sled dress in hydrogen station 11, main sled dress is similar with the structure of reserve sled dress, but still installs main compressor 111 on the main sled dress, through main sled dress and reserve sled dress, conveniently assemble and migrate, promote holistic installation quality.
In this embodiment, the preset gas storage capacity of the backup buffer bottle 211 is 80% of the total gas storage capacity of the main buffer bottle 112.
When the main compressor 11 of the hydrogenation station 11 breaks down, the hydrogenation station 11 is in an abnormal state, at this time, the standby buffer bottle 211 is butted with the hydrogenation station 11, after the interface of the standby buffer bottle 211 is connected with the hydrogenation interface in the hydrogenation station 11, the hydrogenation station 11 hydrogenates the equipment 114 to be hydrogenated continuously through the residual hydrogen in the main buffer bottle 112 and the preset gas storage amount in the standby buffer bottle 211, and the normal work of the hydrogenation station 11 is ensured.
After the hydrogenation of the equipment 114 to be hydrogenated is completed, because the preset gas storage amount of the standby buffer bottle 211 is 80% of the total gas storage amount of the main buffer bottle 112, the gas in the standby buffer bottle 211 is still relatively high-pressure, the hydrogen in the standby buffer bottle 211 is injected into the main buffer bottle 112 through pressure difference, and then the standby filling device is transported to other hydrogenation stations 11 to supplement the gas, so that the subsequent hydrogenation stations 11 in abnormal states are served.
Main buffer bottle 112 has the biggest gas storage volume, total gas storage volume promptly, sets up to 80% through the gas storage volume of predetermineeing with reserve buffer bottle 211, weight when can enough reducing the transportation improves the conveying efficiency, can guarantee again to provide sufficient hydrogen energy for hydrogen station 11 of abnormal state, maintains its normal work.
In this embodiment, the hydrogen energy supply device 113 includes a tube bundle vehicle, and when the tube bundle vehicle is fully loaded, the pressure of the hydrogen energy loaded by the tube bundle vehicle is 20MPa, and the main compressor 111 is a high-pressure compressor of 45MPa, and can compress the hydrogen energy in the tube bundle vehicle to 45MPa, and fill the hydrogen energy into the main buffer tank 112.
The main buffer bottles 112 are divided into at least three groups according to the pressure value in the bottles, and the standby buffer bottles 211 are divided into at least three groups according to the pressure value in the bottles.
When the main compressor 111 continuously compresses and fills the hydrogen energy in the tube bundle vehicle into the main buffer bottle 112, the hydrogen storage capacity in the tube bundle vehicle continuously decreases, and the pressure in the tube bundle vehicle also continuously decreases, the main compressor 111 has a limitation of a compression ratio, for example, under the limitation of a compression ratio of five, the main compressor 111 cannot compress the hydrogen energy of 9MPa in the tube bundle vehicle to 45MPa, that is, the main buffer bottle 112 is divided into a plurality of groups according to the pressure value in the bottle, taking three groups as an example, the main compressor is divided into a high-pressure buffer bottle, a medium-pressure buffer bottle and a low-pressure buffer bottle, so that when the pressure in the tube bundle vehicle decreases, the main compressor 111 can also compress and fill the hydrogen energy in the tube bundle vehicle into the low-pressure buffer bottle under the limitation of the compression ratio, thereby ensuring that the hydrogen storage capacity and the recovery residual pressure in the tube bundle vehicle can be minimized.
Furthermore, by means of the multiple groups of main buffer bottles 112 with different pressures, overlapped hydrogenation of the equipment to be hydrogenated 114 can be achieved, and the hydrogenation efficiency is improved.

Example two
Referring to fig. 2, the present embodiment provides a backup charging system for a hydrogen energy source of a hydrogen refueling station, which is different from the first embodiment in that the hydrogen refueling station 11 further includes: the docking unit 115, the intelligent control unit 116, the pressure difference obtaining unit 117 and the automatic filling unit 118, and the standby filling device 21 further comprises a hydrogen energy source transfer unit 213.
The docking unit 115 is configured to dock the spare filling device 21 with the hydrogenation station 11, and when the gas storage amount in the main buffer bottle 112 in the hydrogenation station 11 is lower than a preset threshold, add hydrogen to the device to be hydrogenated 114 through the spare buffer bottle 211 of the spare filling device 21.
When the hydrogenation station is in an abnormal state, the hydrogenation equipment 114 is hydrogenated through the main buffer bottle 112, so that hydrogen in the main buffer bottle 112 is fully consumed, the pressure in the bottle is reduced, and the subsequent standby buffer bottle 211 is convenient to inject gas into the main buffer bottle 112. When the gas in the main buffer bottle 112 is lower than the preset threshold, the standby buffer bottle 211 is used to hydrogenate the equipment 114.
In this embodiment, the intelligent control unit 116 is configured to obtain pressure values in each group of main buffer bottles 112 or each group of standby buffer bottles 211, and sequentially control each group of main buffer bottles 112 or each group of standby buffer bottles to hydrogenate the equipment to be hydrogenated 114 according to the pressure values in the bottles.
In the first embodiment, the main buffer bottle 112 and the standby buffer bottle 211 are divided into a plurality of groups, since hydrogen is filled through the pressure difference between the buffer bottles and the equipment 114 to be hydrogenated, the pressure difference of the buffer bottle groups with different pressure values is different, the temperature suddenly rises during filling due to too large pressure difference, a potential safety hazard exists, the filling efficiency is affected due to too low pressure difference, and hydrogen is filled into the equipment 114 to be hydrogenated through the pressure values from small to large in sequence, so that the filling efficiency is improved.
In this embodiment, the pressure obtaining unit 117 is configured to obtain a difference between a pressure value in the hydrogen energy source supply device 113 and a pressure value of the device to be hydrogenated 114, and when the difference is higher than a preset difference, control the hydrogen energy source supply device 113 to hydrogenate the device to be hydrogenated 114 through the intelligent control unit 116.
The hydrogen energy supply device 113 can also hydrogenate the device 114 to be hydrogenated, but the pressure difference between the two devices is required to reach a preset difference value, so that the hydrogen storage capacity of the hydrogen energy supply device 113 is further reduced, and the load of the main compressor 111 is reduced.
In this embodiment, the hydrogen energy transfer unit 213 is configured to fill the hydrogen energy in the standby buffer bottle 211 into the main buffer bottle 112 after the standby buffer bottle 211 completes hydrogenation on the equipment 114 to be hydrogenated.
In the first embodiment, when the hydrogenation station is in an abnormal state, the hydrogen gas in the main buffer bottle 112 is consumed first, the pressure in the bottle is reduced, so that a pressure difference exists between the standby buffer bottle 211 and the main buffer bottle 112, and the hydrogen gas in the standby buffer bottle 211 is filled into the main buffer bottle 112, and at this time, the standby filling device can be transported to other hydrogenation stations 11 to replenish the hydrogen gas, so as to serve the hydrogenation stations 11 in other abnormal states.
In this embodiment, the automatic filling unit 118 is configured to control the main compressor 111 to perform hydrogen energy filling on the main buffer bottles 112 to maintain the pressure values in the groups of main buffer bottles 112 when the hydrogen refueling station 11 is in a normal state.
Because the main buffer bottles 112 are divided into a plurality of groups according to different pressure values, when the equipment 114 to be hydrogenated is continuously hydrogenated, the hydrogen storage capacity is consumed, and the pressure is correspondingly reduced, in order to keep different pressure values of the main buffer bottles 112 of each group, the main compressor 111 automatically compresses the hydrogen in the hydrogen energy supply equipment 113, and fills the hydrogen into the main buffer bottles 112 of each group to keep the main buffer bottles 112 of each group at different pressure values.
Through portable reserve filling device, when the hydrogenation station breaks down and can not normally work, can dock with the hydrogenation station, continue for waiting hydrogenation equipment hydrogenation, guaranteed the continuous operation at hydrogenation station, reduce reserve compressor simultaneously, reduced reserve cost that fills the device, and portable design both makes things convenient for the transportation, can provide urgent hydrogenation for hydrogen energy automobile that hydrogen fuel worried about on the road again.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or ambit of the invention as defined in the appended claims.
