Detailed Implementation

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0024] To better understand the purpose, structure, and function of this utility model, a gaseous fuel refueling system of this utility model will be further described in detail below with reference to the accompanying drawings.

[0025] Figure 1 The diagram schematically illustrates a gaseous fuel dispensing system 100 according to the present invention. In such a case... Figure 1In the embodiment shown, the gaseous fuel filling system 100 comprises a supply system 1. In the embodiment, the supply system 1 is configured to output gaseous fuel. Meanwhile, the gaseous fuel filling system 100 further comprises a receiving system 2. In the embodiment, the receiving system 2 is configured to be selectively communicable with the supply system 1 to receive gaseous fuel.

[0026] In this way, the supply system 1 and the receiving system 2 are able to collectively form a passage for gaseous fuel movement in a selective manner, and also enable gaseous fuel located in the supply system 1 to continuously move into the receiving system 2 when the supply system 1 and the receiving system 2 are in communication. Thus, gaseous fuel supply to the receiving system 2 is achieved.

[0027] In one embodiment, as shown in Figure 1 the supply system 1 comprises a storage mechanism 11 for storing gaseous fuel, and a delivery pipeline 12 in communication with the storage mechanism 11. In this way, gaseous fuel located in the storage mechanism 11 is able to move along the delivery pipeline 12.

[0028] Meanwhile, as shown in Figure 1 the receiving system 2 comprises a containing mechanism 21 for receiving gaseous fuel from the storage mechanism 11, and a receiving pipeline 22 in communication with the containing mechanism 21. In the embodiment, the receiving pipeline 22 and the delivery pipeline 12 are configured to be selectively communicable with each other.

[0029] In this way, the storage mechanism 11, the delivery pipeline 12, the receiving pipeline 22, and the containing mechanism 21 are able to collectively form a passage for gaseous fuel movement in a selective manner. Thus, gaseous fuel located in the storage mechanism 11 is able to move along the delivery pipeline 12 and the receiving pipeline 22 which are in communication, and into the containing mechanism 21. Thus, gaseous fuel supply to the containing mechanism 21 is achieved.

[0030] In one embodiment, as shown in Figure 1 the supply system 1 further comprises a filling mechanism 13 disposed between the storage mechanism 11 and the delivery pipeline 12. In the embodiment, the filling mechanism 13 is configured to be in communication with the storage mechanism 11 and the delivery pipeline 12, respectively. Meanwhile, the filling mechanism 13 is configured to allow gaseous fuel from the delivery pipeline 12 to be processed and delivered to the receiving pipeline 22. Specifically, the filling mechanism 13 is provided as a hydrogen dispenser. It is noted that the processing procedure of the hydrogen dispenser for gaseous fuel includes filtering impurities, controlling flow rate, etc. The hydrogen dispenser is well known to those skilled in the art, and thus will not be described here.

[0031] In this way, the gaseous fuel located in the storage mechanism 11 is continuously moved out of the storage mechanism 11 and continuously moved towards the delivery pipeline 12, and the gaseous fuel processed by the filling mechanism 13 is continuously delivered to the delivery pipeline 12.

[0032] In one embodiment, as shown in Figure 1 The supply system 1 further comprises a valve 14 arranged between the storage mechanism 11 and the delivery pipeline 12 and in communication with the storage mechanism 11 and the delivery pipeline 12, respectively. In this embodiment, the valve 14 is configured to selectively open the passage for the movement of the gaseous fuel formed between the storage mechanism 11 and the delivery pipeline 12.

[0033] In this arrangement, the opening or closing of the passage for the movement of the gaseous fuel can be achieved by opening or closing the valve 14. Thus, the operation of supplying or canceling the supply of the gaseous fuel by the supply system 1 can be achieved.

[0034] In one embodiment, as shown in Figure 1 The supply system 1 further comprises a gas valve 111 arranged on the storage mechanism 11, which is used to selectively open the storage mechanism 11.

[0035] In one embodiment, as shown in Figure 1 The receiving system 2 further comprises a valve body 23 arranged between the containing mechanism 21 and the receiving pipeline 22 and in communication with the containing mechanism 21 and the receiving pipeline 22, respectively. In this embodiment, the valve body 23 is configured to selectively open the passage for the movement of the gaseous fuel formed between the containing mechanism 21 and the receiving pipeline 22.

[0036] In this arrangement, the opening or closing of the passage for the movement of the gaseous fuel can be achieved by opening or closing the valve body 23. Thus, the operation of receiving or canceling the receiving of the gaseous fuel by the receiving system 2 can be achieved.

[0037] According to a preferred embodiment of the present application, as shown in Figure 1 The filling head 121 is arranged at the free end of the delivery pipeline 12, and the receiving head 221 is arranged at the free end of the receiving pipeline 22. In this embodiment, the filling head 121 and the receiving head 221 are configured to be selectively fixed together.

[0038] In this arrangement, the delivery pipeline 12 and the receiving pipeline 22 are relatively fixed together by the filling head 121 and the receiving head 221, and the delivery pipeline 12 and the receiving pipeline 22 are communicated with each other to form a stable channel for the gaseous fuel to move along.

[0039] According to a preferred embodiment of the present application, as shown in Figure 1 A filling arm 15 is arranged between the delivery pipeline 12 and the filling head 121. In this embodiment, the filling arm 15 is communicated with the delivery pipeline 12 and the filling head 121 respectively. Meanwhile, the filling arm 15 is arranged between the delivery pipeline 12 and the filling head 121 in an extendable and retractable manner.

[0040] In this way, the length of the filling arm 15 can be adjusted in an extendable and retractable manner. Thus, the relative distance between the filling head 121 and the delivery pipeline 12 can be adjusted. In this arrangement, the length of the filling arm 15 can be adjusted according to the position of the receiving head 221. Thus, the filling head 121 and the receiving head 221 can be better connected.

[0041] In one embodiment, as shown in Figure 1 The filling arm 15 is sleeved on the outer periphery of the delivery pipeline 12. Meanwhile, the filling arm 15 comprises a support plate 151, a first sleeve 152 arranged on the support plate 151 for accommodating the delivery pipeline 12, and a second sleeve 153 rotatably connected with the first sleeve 152.

[0042] Meanwhile, in this embodiment, the filling arm 15 further comprises a third sleeve 154 rotatably connected with the second sleeve 153. In this way, the second sleeve 153 and the third sleeve 154 can move in an extendable and retractable manner.

[0043] In this arrangement, when the delivery pipeline 12 and the receiving pipeline 22 need to be communicated with each other so that the delivery pipeline 12 continuously delivers gaseous fuel to the receiving pipeline 22, the position relationship between the second sleeve 153 and the third sleeve 154 can be adjusted according to the position of the receiving head 221, so that the filling head 121 and the receiving head 221 are communicated with each other.

[0044] Meanwhile, in this process, the support plate 151 can be arranged on a horizontal plane (a foundation and the like), so that the support plate 151 supports the first sleeve 152, the second sleeve 153 and the third sleeve 154. In this way, the delivery pipeline 12 and the receiving pipeline 22 can be stably connected together, and the delivery pipeline 12 and the receiving pipeline 22 can be stably arranged without the continuous application of force by the worker during the delivery of the gaseous fuel.

[0045] In one embodiment, as shown in FIG. 1, the supply system 1 further comprises a first control mechanism 16. In this embodiment, the first control mechanism 16 is in signal connection with the gas valve 111, the filling mechanism 13 and the valve 14, respectively. In the illustrated embodiment, the first control mechanism 16 is connected to the gas valve 111, the filling mechanism 13 and the valve 14 by wire, and the first control mechanism 16 is configured to selectively open the gas valve 111, the filling mechanism 13 and the valve 14. Figure 2

[0046] In this arrangement, when it is necessary to open the gas valve 111, the filling mechanism 13 and the valve 14 to supply the gaseous fuel from the supply system 1 to the receiving system 2, the first control mechanism 16 can transmit a signal to open the gas valve 111, the filling mechanism 13 and the valve 14 to the gas valve 111, the filling mechanism 13 and the valve 14, so as to open the gas valve 111, the filling mechanism 13 and the valve 14, and then supply the gaseous fuel from the supply system 1 to the receiving system 2.

[0047] In one embodiment, as shown in FIG. 1, the receiving system 2 further comprises a second control mechanism 24. In this embodiment, the second control mechanism 24 is in signal connection with the valve body 23. In the illustrated embodiment, the second control mechanism 24 is connected to the valve body 23 by wire, and the second control mechanism 24 is configured to selectively open the valve body 23. Figure 2

[0048] In this arrangement, when it is necessary to open the valve body 23 to receive the gaseous fuel from the supply system 1 by the receiving system 2, the second control mechanism 24 can transmit a signal to open the valve body 23 to the valve body 23, so as to open the valve body 23, and then receive the gaseous fuel from the supply system 1 by the receiving system 2.

[0049] In one embodiment, as shown in FIG. 1, the receiving system 2 further comprises a second control mechanism 24. In this embodiment, the second control mechanism 24 is in signal connection with the valve body 23. In the illustrated embodiment, the second control mechanism 24 is connected to the valve body 23 by wire, and the second control mechanism 24 is configured to selectively open the valve body 23. Figure 2 ​​As shown, the first control mechanism 16 and the second control mechanism 24 are signal connected together. In the embodiment shown, the first control mechanism 16 and the second control mechanism 24 are connected together by wired mode. Meanwhile, the pressure sensor 211 is also provided on the containing mechanism 21 and signal connected together with the second control mechanism 24. The pressure sensor 211 is configured to continuously monitor the pressure information in the containing mechanism 21 and transmit the pressure information to the second control mechanism 24, so as to make the second control mechanism 24 open or close the valve body 23 according to the pressure information.

[0050] In addition, as shown, the second control mechanism 24 can also transmit the pressure information to the first control mechanism 16, so as to make the first control mechanism 16 open or close the gas valve 111, the filling mechanism 13 and the valve 14. In this way, the operation of supplying the gaseous fuel from the supply system 1 to the receiving system 2 and stopping the supply of gaseous fuel is realized. Figure 2

[0051] In this arrangement, when it is needed to supply the gaseous fuel from the supply system 1 to the receiving system 2, first, the filling arm 15 sleeved on the conveying pipeline 12 is adjusted, so that the filling head 121 on the conveying pipeline 12 is located at a position facilitating the connection together with the receiving head 221.

[0052] Meanwhile, the filling head 121 and the receiving head 221 are connected together and the relative fixation between the filling head 121 and the receiving head 221 is realized. In this way, the conveying pipeline 12 and the receiving pipeline 22 are communicated with each other to jointly form a stable channel for the movement of gaseous fuel.

[0053] In addition, the first control mechanism 16 is provided on the supply system 1 and is connected together with the gas valve 111, the filling mechanism 13 and the valve 14 by wired mode. Meanwhile, the second control mechanism 24 is provided on the receiving system 2 and is connected together with the pressure sensor 211 and the valve body 23 by wired mode. Secondly, the first control mechanism 16 and the second control mechanism 24 are connected together by wired mode. In this way, the first control mechanism 16 can open or close the gas valve 111, the filling mechanism 13 and the valve 14, and the second control mechanism 24 can open or close the valve body 23.

[0054] ​In this arrangement, the pressure sensor 211 continuously monitors the pressure information in the containing mechanism 21 and continuously transmits the pressure information to the second control mechanism 24. When the pressure information in the containing mechanism 21 is less than the preset value, the second control mechanism 24 opens the valve body 23. At the same time, the second control mechanism 24 transmits an opening signal to the first control mechanism 16. At this time, when the first control mechanism 16 receives the opening signal, the first control mechanism 16 opens the gas valve 111, the filling mechanism 13, and the valve 14.

[0055] Thus, the gas valve 111, the conveying pipeline 12, the receiving pipeline 22, and the containing mechanism 21 together form a path for the movement of gaseous fuel. At the same time, the filling mechanism 13 continuously processes the gaseous fuel from the conveying pipeline 12. At this time, the gaseous fuel processed by the filling mechanism 13 continuously moves into the containing mechanism 21. In this way, the supply system 1 supplies gaseous fuel to the receiving system 2.

[0056] However, when the pressure sensor 211 monitors the pressure information in the containing mechanism 21 and the pressure information is equal to or greater than the preset value, the second control mechanism 24 closes the valve body 23. At the same time, the second control mechanism 24 transmits a closing signal to the first control mechanism 16. At this time, when the first control mechanism 16 receives the closing signal, the first control mechanism 16 closes the gas valve 111, the filling mechanism 13, and the valve 14. Thus, the supply system 1 stops supplying gaseous fuel to the receiving system 2.

[0057] According to a preferred embodiment of the present application, as shown in Figure 2 The first control mechanism 16 is further provided with a wiring portion 161 for providing different wiring interfaces, so that the first control mechanism 16 can be connected with wires of different specifications. In the illustrated embodiment, the wiring portion 161 is further provided with a first connector 162, and the second control mechanism 24 is further provided with a second connector 241, the first connector 162 and the second connector 241 being configured to be connected with each other, thereby realizing signal transmission between the first control mechanism 16 and the second control mechanism 24.

[0058] In one embodiment, as shown in Figure 1As shown, the receiving system 2 further comprises an emergency stop unit 25 which is in signal connection with the second control mechanism 24. In the embodiment, the emergency stop unit 25 is arranged to output a closing signal to the second control mechanism 24 in a selected manner, so as to make the second control mechanism 24 close the valve body 23 according to the signal, and allow the second control mechanism 24 to transmit the closing signal to the first control mechanism 16, so as to make the first control mechanism 16 close the gas valve 111, the filling mechanism 13 and the valve 14. In this arrangement, the operator can forcibly disconnect the gaseous fuel transportation path formed between the supply system 1 and the receiving system 2 according to the site conditions, thereby improving the safety of gaseous fuel transportation.

[0059] The operation of the gaseous fuel filling system 100 according to the present application is as follows.

[0060] First, the filling arm 15 sleeved on the conveying pipeline 12 is adjusted, so that the filling head 121 on the conveying pipeline 12 is located at a position facilitating connection with the receiving head 221.

[0061] At the same time, the filling head 121 and the receiving head 221 are connected together, and the relative fixation between the filling head 121 and the receiving head 221 is achieved. In this way, the conveying pipeline 12 and the receiving pipeline 22 are communicated with each other to form a stable gaseous fuel transportation path together.

[0062] In addition, the first control mechanism 16 is arranged on the supply system 1 and is connected with the gas valve 111, the filling mechanism 13 and the valve 14 through wires. Meanwhile, the second control mechanism 24 is arranged on the receiving system 2 and is connected with the pressure sensor 211 and the valve body 23 through wires. Then, the first control mechanism 16 and the second control mechanism 24 are connected through wires. In this way, the first control mechanism 16 can open or close the gas valve 111, the filling mechanism 13 and the valve 14, and the second control mechanism 24 can open or close the valve body 23.

[0063] In this arrangement, the pressure sensor 211 continuously monitors the pressure information in the containing mechanism 21 and continuously transmits the pressure information to the second control mechanism 24. When the pressure information in the containing mechanism 21 is less than a preset value, the second control mechanism 24 opens the valve body 23. Meanwhile, the second control mechanism 24 transmits an opening signal to the first control mechanism 16. At this time, when the first control mechanism 16 receives the opening signal, the first control mechanism 16 opens the gas valve 111, the filling mechanism 13 and the valve 14.

[0064] Thus, the storage mechanism 11, the delivery pipeline 12, the receiving pipeline 22 and the containing mechanism 21 jointly form a path for the gaseous fuel to move. Meanwhile, the filling mechanism 13 continuously processes the gaseous fuel from the delivery pipeline 12. At this time, the gaseous fuel processed by the filling mechanism 13 continuously moves into the containing mechanism 21. In this way, the gaseous fuel supply work of the supply system 1 to the receiving system 2 is realized.

[0065] However, when the pressure information of the containing mechanism 21 monitored by the pressure sensor 211 is equal to or greater than the preset value, the second control mechanism 24 will close the valve 23. Meanwhile, the second control mechanism 24 will also transmit a closing signal to the first control mechanism 16 at this time. When the first control mechanism 16 receives the closing signal, the first control mechanism 16 will close the gas valve 111, the filling mechanism 13 and the valve 14. Thus, the gaseous fuel supply work of the supply system 1 to the receiving system 2 is stopped.

[0066] However, when an emergency occurs during the gaseous fuel delivery, it is necessary to forcibly suspend the gaseous fuel supply work of the supply system 1 to the receiving system 2, the emergency stop part 25 is started. At this time, the emergency stop part 25 will output a closing signal to the second control mechanism 24, so that the second control mechanism 24 closes the valve 23 according to the signal. Meanwhile, the second control mechanism 24 will also transmit the closing signal to the first control mechanism 16, so that the first control mechanism 16 closes the gas valve 111, the filling mechanism 13 and the valve 14. Thus, the gaseous fuel delivery path between the supply system 1 and the receiving system 2 is forcibly disconnected.

[0067] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the purpose and scope of the present application. They should be covered in the scope of the claims of the present application.
