[0028] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0029] To better understand the technical solution of this application, the emission control vehicle of this application will be described in detail below with reference to the accompanying drawings. Unless otherwise specified, the features of the following embodiments and implementation methods can be combined with each other.

[0030] Figure 1 The diagram shown is a schematic diagram of an emission control vehicle 10 according to an embodiment of this application. Figure 2 As shown Figure 1 A partial schematic diagram of the emission control vehicle 10 from another angle. Figure 3 As shown Figure 1 A partial schematic diagram of the emission control vehicle 10 from another angle. Figure 4 As shown Figure 1 The diagram shows a partial system schematic of the emission control vehicle. (See also...) Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this application provides an emission control vehicle 10, which includes a chassis beam 11, an oil tank 12, and a detection component 13.

[0031] The oil tank 12 is located above the chassis beam 11, which supports the oil tank 12. The oil tank 12 stores oil, and a bottom valve 14 is located at the bottom of the tank, corresponding to the oil inlet 15. The bottom valve 14 can be controlled to open or close the oil inlet 15. When the bottom valve 14 is open, the oil inlet 15 is open, allowing oil to enter the oil tank 12. When the bottom valve 14 is closed, the oil inlet 15 is closed.

[0032] The detection component 13 is located at the rear of the chassis beam 11, and can be positioned below the chassis beam 11. The detection component 13 includes a wellhead connector 16 and a first connecting pipe 17. The wellhead connector 16 is used to connect to a wellhead valve. One end of the first connecting pipe 17 is connected to the wellhead connector 16, and the other end is connected to the oil inlet 15 via a bottom valve 14. The first connecting pipe 17 can be a rubber hose. The wellhead connector 16 can be located to the side of the chassis beam 11, and the first connecting pipe 17 can be located behind the chassis beam 11, resulting in a more compact structural arrangement. When the wellhead connector 16 is connected to the wellhead valve and the bottom valve 14 is open, aviation fuel in the wellhead valve can be transported to the oil tank 12 through the wellhead connector 16 and the first connecting pipe 17. This allows for functional testing of the wellhead valve using only the discharge vehicle 10.

[0033] The emission operation vehicle 10 provided in this application includes an oil tank 12 and a detection component 13. The well connector 16 of the detection component 13 is connected to the well valve. When the bottom valve 14 is opened, the aviation fuel in the well valve can be recovered into the oil tank 12 through the first connecting pipe 17 of the detection component 13. The well valve is inspected by recovering the aviation fuel. In this way, the well valve maintenance and inspection function can be integrated into the emission operation vehicle 10. The well valve maintenance and inspection can be realized using only the emission operation vehicle 10. There is no need for pipeline refueling trucks and tank refueling trucks to work together. The well valve maintenance and inspection can be realized quickly, with high maintenance and inspection efficiency and low equipment and labor costs.

[0034] In one embodiment, the detection component 13 further includes a flow meter 18, which is disposed in the first connecting pipe 17 and used to detect the flow rate of the oil flowing through the first connecting pipe 17. Thus, the flow rate of the oil flowing through the first connecting pipe 17 can be determined by the flow meter 18, thereby determining whether the aviation fuel in the well valve is recovered to the oil tank 12 through the first connecting pipe 17. Inspecting the well valve by measuring the flow rate with the flow meter 18 and recovering aviation fuel is a more accurate and reliable method of inspection.

[0035] In one embodiment, the emission control vehicle 10 further includes a fuel filling assembly 19, located at the rear of the chassis beam 11. The fuel filling assembly 19 can be located below the chassis beam 11. In one embodiment, both the detection assembly 13 and the fuel filling assembly 19 are located at the rear of the chassis beam 11 and below it. This layout is more reasonable and compact. The fuel filling assembly 19 includes a fuel filling connector 20 and a second connecting pipe 21, wherein the second connecting pipe 21 can be a rubber hose. The fuel filling connector 20 is used to connect with an external refueling connector. One end of the second connecting pipe 21 is connected to the fuel filling connector 20, and the other end is connected to the fuel inlet 15 through a bottom valve 14. In this embodiment, the second connecting pipe 21 extends along the width direction of the chassis beam 11. The external refueling connector can be an aircraft refueling connector, which can be located in the fuel depot. When the bottom valve 14 is opened, aviation fuel in the fuel depot can be transported to the fuel tank 12 through the fuel filling connector 20 and the second connecting pipe 21, thereby realizing the fuel filling function. This allows the oil loading function and the maintenance and inspection function of the well valve to be integrated into the discharge operation vehicle 10, replacing the traditional working mode of pipeline refueling truck and tank refueling truck working together, which greatly improves work efficiency, facilitates manual operation, and is simple to operate.

[0036] In one embodiment, the oil filling assembly 19 and the detection assembly 13 are arranged at intervals along the length of the chassis beam 11. This facilitates the separate operation of the oil filling assembly 19 and the detection assembly 13.

[0037] In one embodiment, the fuel filling assembly 19 further includes a first valve 22, which is located between the fuel filling connector 20 and the second connecting pipe 21. The first valve 22 can be a ball valve and can be manually opened or closed. When both the bottom valve 14 and the first valve 22 are open, the fuel filling connector 20 is connected to the fuel inlet 15, and aviation fuel can enter the fuel tank 12 through the fuel filling connector 20, the second connecting pipe 21, and the fuel inlet 15 to achieve fuel filling. When at least one of the bottom valve 14 and the first valve 22 is closed, the fuel filling connector 20 and the bottom valve 14 are disconnected. In this way, the fuel filling connector 20 and the bottom valve 14 can be disconnected automatically and manually, which is simple and highly reliable.

[0038] In one embodiment, the emission control vehicle 10 further includes a controller and a control air circuit (not shown). The controller can be an on-board PLC. The control air circuit includes a solenoid valve. The solenoid valve is connected between the controller and the bottom valve 14. The oil filling assembly 19 also includes a first proximity switch 23 connected to the controller. The first proximity switch 23 is located on the side of the oil filling connector 20, wherein the first proximity switch 23 can be installed on the first valve 22. When the oil filling connector 20 is connected to an external refueling connector, the first proximity switch 23 is triggered. The controller controls the bottom valve 14 to open via the solenoid valve according to the trigger signal of the first proximity switch 23. When the oil filling connector 20 is connected to an external refueling connector, the first valve 22 is connected to the aircraft refueling connector. The first proximity switch 23 is triggered. The controller receives the trigger signal of the first proximity switch 23 and feeds it back to the solenoid valve. After receiving the first feedback signal, the solenoid valve opens the bottom valve 14, thereby realizing the oil filling function.

[0039] In one embodiment, the emission control vehicle 10 further includes a limiting structure 24 and a limiting cylinder 25. The limiting cylinder 25 includes an output end 26, which is connected to the limiting structure 24. A manhole connector 16 is disposed on the limiting structure 24. When the output end 26 of the limiting cylinder 25 extends, the manhole connector 16 is limited by the limiting structure 24, thus locking the manhole connector 16 and preventing it from falling off. When the output end 26 of the limiting cylinder 25 retracts, the limiting structure 24 unlocks, and the manhole connector 16 can be disassembled. A solenoid valve and a controller can be connected to the limiting cylinder 25. The controller is used to control the retraction of the limiting cylinder 25 via the solenoid valve based on the trigger signal of the first proximity switch 23. After receiving a first feedback signal, the solenoid valve causes the limiting cylinder 25 to retract, thereby enabling the unlocking and disassembly of the manhole connector 16.

[0040] In one embodiment, the detection component 13 further includes a second proximity switch (not shown) connected to the controller, the second proximity switch being located on the side of the well connector 16. When the well connector 16 is connected to the well valve, the second proximity switch is triggered, and the controller controls the bottom valve 14 to open via a solenoid valve based on the trigger signal of the second proximity switch. When the well connector 16 is connected to the well valve, the second proximity switch is triggered, the controller receives the trigger signal of the second proximity switch and feeds it back to the solenoid valve. After receiving the second feedback signal, the solenoid valve opens the bottom valve 14, thereby enabling the functional detection of the well valve.

[0041] In one embodiment, the detection component 13 further includes a second valve 27, which is located on the first connecting pipe 17. The second valve 27 can be positioned closer to the bottom valve 14 than the wellhead connector 16. The second valve 27 can be a clamp ball valve, which can be manually opened or closed. When both the bottom valve 14 and the second valve 27 are open, the wellhead connector 16 is connected to the inlet 15, and aviation fuel can enter the oil tank 12 through the wellhead connector 16, the first connecting pipe 17, and the inlet 15, thereby enabling the functional detection of the wellhead valve. When at least one of the bottom valve 14 and the second valve 27 is closed, the wellhead connector 16 and the bottom valve are disconnected. This allows for automatic and manual disconnection of the wellhead connector 16 and the bottom valve 14, resulting in a simple and highly reliable implementation.

[0042] In one embodiment, a high-level valve 28 is provided at the top of the oil tank 12. The high-level valve 28 is connected to the control terminal of a solenoid valve, which controls the opening or closing of the bottom valve 14. When the oil in the oil tank 12 reaches the high-level valve 28 at the top of the oil tank 12, the high-level valve 28 can control the bottom valve 14 to close via the solenoid valve, thus preventing the delivery of aviation fuel into the oil tank 12 and preventing the aviation fuel in the oil tank 12 from overflowing. This high-level control ensures the safe filling of the oil tank 12.

[0043] In one embodiment, the emission control vehicle 10 further includes a mounting bracket 29, which includes a first support portion 30 and a second support portion 31. The first support portion 30 is connected to the chassis beam 11 and can be fixedly connected to the chassis beam 11 with screws. The first support portion 30 extends along the height direction of the emission control vehicle 10, and the second support portion 31 is connected to the first support portion 30 and extends along the length direction of the emission control vehicle 10. The second support portion 31 can extend along the length direction of the emission control vehicle 10 from the side of the first support portion 30 away from the chassis beam 11. The second support portion 31 supports the first connecting pipe 17, thus providing good support for the first connecting pipe 17 and a more compact layout.
