[0006] When the generator generates electricity, the smoke generated by the generator is discharged along the smoke exhaust pipeline to the port of the smoke exhaust pipe close to the rain-proof cap. The smoke will continuously accumulate and the pressure will continuously increase. When the pressure value of the smoke is greater than the weight of the rain-proof cap, the smoke can push open the rain-proof cap, and the smoke can be discharged from the smoke exhaust pipe. After the generator stops running, the smoke exhaust pressure continuously decreases. After the pressure value of the smoke is less than the weight of the rain-proof cap, the rain-proof cap covers the smoke exhaust pipe again under the action of gravity, thereby automatically realizing the opening and closing of the smoke exhaust pipe, further helping to prevent water and sand and dust, having better sealing performance and being convenient and reliable.

After the pressure value of the smoke is less than the weight of the rain-proof cap, the rotating shaft rotates in the reverse direction at this time, and the rain-proof cap covers the smoke exhaust pipe again under the action of gravity. During the above process, it can be ensured that the rain-proof cap covers the smoke exhaust pipe when not generating power, so as to have better sealing performance, stronger waterproof and dust-proof capabilities, and is also more convenient and reliable to use.

[0027] This embodiment provides a heat-insulating flue device for a mobile power station vehicle.
[0028] Reference Figure 1 , a heat-insulating flue device for a mobile power station vehicle, includes a connecting seat 1, a rain-proof cap assembly 2 and a smoke exhaust pipe 3.
[0029] The connecting seat 1 can be installed on the cabin top of the mobile power station vehicle. The rain-proof cap assembly 2 is installed on the connecting seat 1. The connecting seat 1 is provided with mounting holes, and the smoke exhaust pipe 3 is fixedly arranged through the mounting holes. And sealant is applied at the penetration part of the smoke exhaust pipe 3 and the connecting seat 1 to improve the waterproof effect at the penetration part.
[0030] Reference Figure 1 , the rain-proof cap assembly 2 includes a bracket 21, a first fastener 22, a rotating member 23 and a rain-proof cap 24. The bracket 21 is installed on the connecting seat 1 through the first fastener 22, and there are multiple first fasteners 22. The rotating member 23 is installed on the bracket 21, and the rain-proof cap 24 is installed on the rotating member 23. The rain-proof cap 24 can cover one end of the smoke exhaust pipe 3 close to the connecting seat 1, and the other end of the smoke exhaust pipe 3 can extend into the cabin where the generator is installed, so as to realize the connection with the cabin where the generator is installed.
[0031] Among them, reference Figure 1 , an abutting portion 211 for abutting against the rain-proof cap 24 is integrally formed on the bracket 21. The abutting portion 211 is used to prevent the rain-proof cap 24 from rotating excessively, so as to avoid the situation that the rain-proof cap 24 cannot cover the smoke exhaust pipe 3.
[0032] Reference Figure 1 and Figure 2, the first fastener 22 includes a bolt 221, a spring washer 222 and a flat washer 223. The bolt 221 threadedly connects the bracket 21 to the connecting seat 1 through a nut. The flat washer 223 and the spring washer 222 are pressed between the connecting seat 1 and the nut, and the flat washer 223 is located between the spring washer 222 and the connecting seat 1. Among them, the flat washer 223 can increase the contact area for the spring washer 222, and the spring washer 222 can give a elastic force to the nut after the nut is tightened, reducing the possibility of the nut loosening. Among them, the bolt 221 is a bolt 221 with a specification of M6×20. At the same time, an embedded plate 8 is fixedly connected to the connecting seat 1, and the bolt 221 passes through the embedded plate 8. The setting of the embedded plate 8 can facilitate the staff to tap the thread, so that the bolt 221 can pass through the connecting seat 1 better.
[0033] Reference Figure 3 and Figure 4 , the rotating member 23 includes a fixed seat 231, a rotating shaft 232 and a connecting plate 233. The fixed seat 231 is horizontally and fixedly connected to the bracket 21, the rotating shaft 232 is rotatably passed through the fixed seat 231, one end of the connecting plate 233 is fixedly connected to the rotating shaft 232, and the other end is fixedly connected to the rain cap 24.
[0034] When the generator of the mobile power station vehicle is not generating electricity, no smoke is generated in the cabin. At this time, the rain cap 24 covers the smoke exhaust pipe 3, thereby reducing the possibility of water and sand dust entering the smoke exhaust pipe 3. When the generator in the cabin generates electricity, the smoke generated by the generator flows along the smoke exhaust pipe 3 to the port of the smoke exhaust pipe 3 close to the rain cap 24. The smoke will continuously accumulate and the pressure will continuously increase. When the pressure value of the smoke is greater than the weight of the rain cap 24, the smoke can push open the rain cap 24. At this time, the rotating shaft 232 rotates, and the smoke can be discharged from the smoke exhaust pipe 3. When the generator stops, the pressure of the exhaust smoke continuously decreases. After the pressure value of the smoke is less than the weight of the rain cap 24, at this time, the rotating shaft 232 rotates in the reverse direction, and the rain cap 24 falls under the action of gravity and covers the smoke exhaust pipe 3.
[0035] In the above process, the rain cap 24 only opens when the generator is working, and covers the smoke exhaust duct when the generator is not working, avoiding the opening of the smoke exhaust pipe 3 being in an open state for a long time. Therefore, it has better sealing performance, strong waterproof and sand dust prevention ability, and is convenient and reliable to use.
[0036] Reference Figure 2 , a heat insulation layer 4 is also sleeved outside the smoke exhaust pipe 3. Since the smoke generated by the generator is relatively hot, it will make the smoke exhaust pipe 3 hot. The setting of the heat insulation layer 4 can effectively isolate the heat. In the embodiment of the present application, the heat insulation layer 4 is made of heat insulation rock wool material. The heat insulation rock wool material has good heat insulation effect and low cost, so the cost performance is high.
[0037] Meanwhile, the bottom of the heat insulation layer 4 is fixedly connected to the top of the cabin body through a plurality of second fasteners 5, and the plurality of second fasteners 5 are evenly distributed along the central axis of the heat insulation layer 4. The second fasteners 5 are hexagon socket countersunk head screws M6×25. A gasket 6 is further provided between the second fasteners 5 and the top of the cabin body, and the second fasteners 5 press the gasket 6 against the top of the cabin body, thereby reducing the possibility of rainwater entering the cabin body from the heat insulation layer 4.
[0038] A retaining ring 7 is also sleeved and fixed outside the heat insulation layer 4, and the retaining ring 7 is fixedly connected to the connecting seat 1. The setting of the retaining ring 7 can first block rainwater, and second, can support the exhaust pipe 3 to prevent the exhaust pipe 3 from moving downward.
[0039] This embodiment also provides a mobile power station vehicle.
[0040] The mobile power station vehicle includes a vehicle body and a heat insulation flue device for the mobile power station vehicle provided on the vehicle body. Since the heat insulation flue device for the mobile power station vehicle has been described in detail, it will not be elaborated here again.
[0041] As described above, the above embodiments are only used to introduce the technical solutions of the present invention in detail, but the descriptions of the above embodiments are only used to help understand the method and its core idea of the present invention, and should not be construed as a limitation of the present invention. Those skilled in the art of this technology can easily think of changes or substitutions within the technical scope disclosed by the present invention, and all of them should be covered within the protection scope of the present invention.
