It should be appreciated that the present application can be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and fully convey the scope of the application to those skilled in the art.

[0033] In order to further illustrate the principles and configurations of the present application, the preferred embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0034] The present application provides a fuel supply skid device, which has high integration, can be installed in advance and then transported to the station, reduces a large amount of on-site construction, improves installation efficiency, and greatly reduces the investment cost of manpower and material resources.

[0035] The fuel can be hydrogen or other dangerous gas. The fuel supply skid device is described below with the fuel being hydrogen.

[0036] Figure 1 A schematic diagram of the fuel supply skid device is shown, referring to Figure 1 The fuel supply skid device 1 includes a skid body 11 and process equipment, filling equipment, a control system, and a power supply system arranged on the skid body 11.

[0037] The skid body 11 can only include a bottom base, or can include a side wall and a top plate around the bottom base, i.e., in the form of a box.

[0038] The process equipment is used to pressurize hydrogen. Specifically, the process equipment includes a hydrogen compressor, a gas unloading column, a safety diffusing pipe, a micro-channel heat exchanger, and a pipeline connecting the above.

[0039] The unloading column is used to unload the hydrogen in the hydrogen transport vehicle to the hydrogen compressor, and the hydrogen compressor pressurizes the hydrogen and then delivers the hydrogen to the fixed hydrogen storage bottle group in the hydrogen filling station.

[0040] The filling device is connected with the process equipment and is used to provide hydrogen outside. The filling device integrates filling, pricing display, metering, etc. The filling device includes the hydrogen filling machine 131 and the hydrogen filling control module. The shell of the hydrogen filling machine 131 is explosion-proof, and the hydrogen filling control module is integrated in the shell of the hydrogen filling machine 131.

[0041] When a vehicle comes to the station to fill hydrogen, the hydrogen in the fixed hydrogen storage bottle group is used to fill the fuel cell vehicle with hydrogen through the hydrogen filling machine 131 by using the pressure difference.

[0042] The filling device and the process equipment are arranged adjacent to each other, and the outer edges of the filling device and the process equipment are taken as the centers to radiate outward with a radius R to divide the dangerous area 111 and the safe area 112. The dangerous area 111 is in the area covered by the radius R, the safe area 112 is outside the area covered by the radius R, and the radius R is equal to or greater than 4.5 m.

[0043] The filling device is located at the edge of the pry body 11 to facilitate filling.

[0044] For example, the filling device, the process equipment, and the control system are arranged in sequence along the longitudinal direction of the pry body 11. At this time, the edge of the process equipment close to the control system is taken as the center to draw a circle with a radius R, and the area outside the circle is the safe area 112.

[0045] Alternatively, the filling device and the process equipment are arranged in the longitudinal direction, and the control system is arranged in the transverse direction of the two. At this time, the edges of the process equipment and the filling device close to the control system are taken as the centers to draw a circle with a radius R, and the area outside the circle is the safe area 112.

[0046] The filling device includes the filling control machine, the filling machine, and the instrument. The instrument is arranged on the filling machine or the pipeline to display various data. For example, the instrument includes the flow meter 132, the pressure gauge, and the thermometer.

[0047] The filling control machine is integrated in the filling machine, and the shell of the filling machine is explosion-proof. The filling control machine is used to control the filling machine.

[0048] The application creatively divides the dangerous area 111 and the safe area 112 on the pry body 11, and then arranges various types of equipment or structures in the dangerous area 111 and the safe area 112, respectively.

[0049] The control system includes the control cabinet 141, the safety PLC system 142, the industrial computer 143, and the display device 144.

[0050] The control cabinet 141 is disposed in the danger zone 111. Specifically, the control cabinet 141 is an explosion-proof cabinet with an explosion-proof grade of Exd px II C T4 Gb and a protection grade of IP65.

[0051] Figure 2 Shows a front view of the control cabinet 141, see Figure 2 The control cabinet 141 includes a cabinet body, the interior of which is divided vertically into a positive pressure chamber 1411 and an accommodation chamber 1412. In this embodiment, the positive pressure chamber 1411 and the accommodation chamber 1412 are separated by a partition. The area above the partition is the positive pressure chamber 1411, and the area below the partition is the accommodation chamber 1412. The partition is provided with a wire hole.

[0052] The cabinet is equipped with a front door that opens left and right. It is sealed with a sealing strip and secured externally with stainless steel bolts. Bolts are located at each corner of the door, with the distance between adjacent bolts being 160mm to 180mm. The door's opening angle is equal to or greater than 110°.

[0053] The left panel of the front door is opened to install a signal light 1413 and a button 1414. The right panel of the front door is installed with an operating member 1415 and a button 1414 of a miniature circuit breaker.

[0054] A grounding device is welded at the connection between the front door and the cabinet body.

[0055] A slight positive pressure is achieved in the positive pressure chamber 1411 by introducing positive pressure inert gas, thereby preventing dangerous gases from entering and achieving explosion protection.

[0057] Furthermore, the control cabinet 141 also includes a stabilization module to ensure the stability of micro-positive pressure. The stabilization module includes a pressure monitoring unit and a signal output unit. The pressure detection unit is used to monitor the real-time pressure in the positive pressure chamber 1411, and transmit the detected real-time pressure to the signal output unit. The signal output unit receives the real-time pressure and compares it with a preset pressure range. When the real-time pressure is not within the preset pressure range, the signal output unit outputs a pressure abnormality signal. It has its own control system. After the gas source is introduced, the system will automatically adjust the pressure entering the cavity and monitor it in real time. Once an abnormality occurs, it will automatically send a signal. The signal is connected in series to the coil of the main power circuit breaker of the equipment through a hard-wired loop, thereby cutting off the main power and achieving power-off protection.

[0058] The breaker is arranged in the positive pressure cavity 1411, the control cabinet 141 is externally provided with an operating member 1415, the operating member 1415 is electrically connected with the breaker, and the breaker is opened and closed through the operation of the operating member 1415.
