Description

Technical Field

[0001] The utility model relates to a glass fiber reinforced plastic air duct, in particular to a glass fiber reinforced plastic air duct for rail vehicles, belonging to the technical field of rail vehicles. Background Art

[0002] Rail vehicles are the vehicles used in rail transit. Rail transit refers to a class of transportation tools or transportation systems where the operating vehicles need to run on specific tracks. The most typical rail transit is the railway system composed of traditional trains and standard railways. With the diversified development of train and railway technologies, rail transit presents more and more types, not only covering long-distance land transportation but also widely used in medium and short-distance urban public transportation.

[0003] Rail transit such as subways usually sets up air ducts to assist vehicle ventilation. Common air ducts are usually of the passive ventilation type, that is, the ventilation ducts only play the role of a passage, without setting up an exhaust system to assist the air flow, thus resulting in low ventilation efficiency of the air ducts. Summary of the Invention

[0004] The purpose of the utility model is to provide a glass fiber reinforced plastic air duct for rail vehicles to solve the problem of low ventilation efficiency of the air duct in the prior art.

[0005] The utility model is realized through the following technical solutions: A glass fiber reinforced plastic air duct for rail vehicles includes a vehicle plate. The upper surface of the vehicle plate is fixedly connected with an outer plate. The left side surface of the outer plate is fixedly connected with an air intake grille. The inner top wall of the outer plate is rotatably connected with a turntable. The outer surface of the turntable is fixedly connected with a plurality of wind-receiving plates arranged in a circumferential manner.

The upper surface of the vehicle plate is fixedly connected with a collection box. The upper surface of the collection box is fixedly connected with a vertical plate. The upper surface of the collection box is fixedly connected with a wind guiding block.

[0006] Preferably, the wind guiding block is located on the right side of the collection box. The vertical plate is inclined and connected with the wind guiding block, which is beneficial to the stability of the wind guiding block. When the external air enters, it contacts the wind guiding block under the guidance of the vertical plate, and then enters through the gap above the wind guiding block under the guidance of the wind guiding block and contacts the wind-receiving plates to drive the turntable to rotate.

[0007] Preferably, the inner top wall of the outer plate is fixedly connected with an auxiliary block. The auxiliary block is located above the left of the baffle. The wind-receiving surface of the auxiliary block is concave. The shape of the baffle is C-shaped, which is beneficial to the stability of the baffle. When the vehicle is running in rainy or foggy weather, the humid water vapor enters through the air intake grille. The C-shaped baffle can prevent rainwater from flowing directly in, thus maintaining the overall stability.

[0008] Preferably, an air inlet is provided on the upper surface of the vehicle board. An air inlet pipe is fixedly connected to the upper surface of the air inlet. A protective sleeve is sleeved above the air inlet pipe. Two fixing rods are fixedly connected to the outer surface of the protective sleeve. The other end of one fixing rod is fixedly connected to the outer plate, and the other end of the other fixing rod is fixedly connected to the vertical plate, which is beneficial to the stability of the protective sleeve. The protective sleeve can prevent the remaining water mist from directly entering the air inlet.

[0009] Preferably, a filter plate is installed on the upper surface of the vehicle board. The filter plate is located below the fan blade, which is beneficial to the stability of the filter plate. The rotation of the fan blade drives the air inside the vehicle to enter above the filter plate from the filter plate and be carried away by the flow of external air as a whole.

[0010] Preferably, an exhaust grille is fixedly connected to the right side surface of the outer plate, and a shielding plate is fixedly connected to the right side surface of the outer plate, which is beneficial to the stability of the exhaust grille and further maintains the overall stability.

[0011] Preferably, the bottom surface of the collection box is communicated with an external drain pipe. The collection box is located on the left side of the fan blade, which is beneficial to the stability of the collection box. The collection box can collect the liquid water formed by the liquefaction of the remaining water vapor entering from the baffle and discharge it from the external drain pipe, which is beneficial to the overall stability.

[0012] The present utility model provides a fiberglass air duct for a rail vehicle, and the beneficial effects thereof are as follows:

[0013] For this fiberglass air duct for a rail vehicle, by providing a wind-receiving plate, when the rail vehicle is moving forward, the outside air enters the interior of the whole through the air inlet grille and blows the wind-receiving plate, so that the wind-receiving plate drives the turntable to rotate. The turntable drives the fan blade to rotate, thereby assisting the air circulation inside the vehicle, and solving the problem of low ventilation efficiency of the air duct in the prior art.

[0014] For this fiberglass air duct for a rail vehicle, by providing an air inlet pipe, when the air inside the vehicle is discharged through the exhaust grille, the internal air pressure decreases. At this time, the fresh outside air can enter the interior of the whole through the air inlet pipe, thereby enabling the air inside the vehicle to complete the conversion, which is beneficial to the air circulation inside the vehicle.

[0023] Please refer with emphasis to Figure 1 , Figure 3 and Figure 4 , the air guide block 11 is located on the right side of the collection box 9, the vertical plate 10 is inclined and the vertical plate 10 is connected to the air guide block 11, which is beneficial to the stability of the air guide block 11. When the external air enters, it contacts the air guide block 11 under the guidance of the vertical plate 10, and then enters through the gap above the air guide block 11 under the guidance of the air guide block 11 and contacts the wind-receiving plate 5 and pushes the turntable 4 to rotate. An auxiliary block 12 is fixedly connected to the inner top wall of the outer board 2, the auxiliary block 12 is located above the left of the baffle 8, the wind-receiving surface of the auxiliary block 12 is concave, and the shape of the baffle 8 is C-shaped, which is beneficial to the stability of the baffle 8. When the vehicle is driving in rainy and foggy weather, the humid water vapor enters through the intake grille 3, and the C-shaped baffle 8 can prevent rainwater from flowing directly in, thereby maintaining the overall stability.

[0024] Please refer with emphasis to Figure 1 , Figure 2 , Figure 3 and Figure 4, an air inlet is provided on the upper surface of the vehicle floor 1. The upper surface of the air inlet is fixedly connected with an air inlet pipe 13. A protective sleeve 14 is sleeved above the air inlet pipe 13. Two fixing rods 15 are fixedly connected to the outer surface of the protective sleeve 14. The other end of one fixing rod 15 is fixedly connected with the outer plate 2, and the other end of the other fixing rod 15 is fixedly connected with the vertical plate 10, which is beneficial to the stability of the protective sleeve 14. The protective sleeve 14 can prevent the remaining water mist from directly entering the air inlet. A filter plate 16 is installed on the upper surface of the vehicle floor 1. The filter plate 16 is located below the fan blade 7, which is beneficial to the stability of the filter plate 16. The rotation of the fan blade 7 drives the air inside the vehicle to enter above the filter plate 16 from the filter plate 16 and be carried away from the whole by the flow of external air.

[0025] Please refer particularly to Figure 1 , Figure 2 , Figure 3 and Figure 4 , an exhaust grille 17 is fixedly connected to the right side surface of the outer plate 2. A shielding plate 18 is fixedly connected to the right side surface of the outer plate 2, which is beneficial to the stability of the exhaust grille 17 and thus maintains the overall stability.

[0026] When the present utility model is in use: when the vehicle is in a forward state, fresh air from the outside enters the interior of the whole through the air inlet grille 3. Then, the C-shaped baffle 8 cooperates with the auxiliary block 12 to divert the air. Then, the air contacts the vertical plate 10. Under the diversion of the vertical plate 10, the air contacts the air guiding block 11. Then, under the diversion of the air guiding block 11, it enters through the gap above the air guiding block 11 and contacts the air receiving plate 5 and pushes the turntable 4 to rotate. The rotation of the turntable 4 drives the driven rod 6 to rotate. The rotation of the driven rod 6 drives the fan blade 7 to rotate. The rotation of the fan blade 7 drives the air inside the vehicle to enter above the filter plate 16 from the filter plate 16 and be carried away from the whole by the flow of external air. At the same time, the flow of external air above the filter plate 16 reduces the pressure above, and the air pressure inside the vehicle pushes the air inside the vehicle to enter above the filter plate 16 to assist the air circulation.

[0027] After the air inside the vehicle is discharged through the exhaust grille 17, the air pressure inside decreases. At this time, fresh air from the outside can enter the interior of the whole through the intake pipe 13, thereby enabling the air inside the vehicle to complete the conversion, which is beneficial to the air circulation inside the vehicle. When there is rainy or foggy weather, the humid water vapor enters through the intake grille 3. The C-shaped baffle 8 can prevent rainwater from flowing directly in. The remaining water vapor collides with the vertical plate 10 after entering and liquefies into liquid water. The collection box 9 can collect the liquid water liquefied from the remaining water vapor entering from the baffle 8 and discharge it through the external drainage pipe, which is beneficial to the stability of the whole.
