An easy-to-clean air outlet structure for rail vehicles

Abstract

To address the problem of existing air duct and vent structures being difficult to clean, thus affecting airflow efficiency, air quality, and equipment lifespan, this utility model provides an easy-to-clean vent structure for rail vehicles, including a wall panel body, an air outlet, an air outlet retainer, a cover plate, and fasteners. The wall panel body has a closed air cavity at the air duct, with the wall panel surfaces around the air cavity lower than the main wall panel surface, forming a stepped structure. The cover plate has the same shape as the lower wall panel around the air cavity, and its thickness is equal to the step height between the wall panel surfaces around the air cavity and the main wall panel surface. The cover plate is fixedly connected to the wall panel body via fasteners. An air outlet retainer is fixedly connected to the end of the cover plate near the air cavity along its entire circumference. The air outlet is located at the opening of the air cavity, and a retainer is provided at the outer end of the air outlet along its circumference. The air outlet is fixedly connected to the air outlet retainer via the retainer. Its advantage is that this structure allows for the individual disassembly of the air outlet or the complete disassembly of the vent module, enabling direct and thorough cleaning of the air cavity.

Description

Technical Field

[0001] The utility model relates to a rail vehicle, in particular to an easy-to-clean air outlet of the rail vehicle. Background Art

[0002] Rail vehicles are equipped with air ducts, which are located behind the outermost wall panels, and air outlets are located outside the air ducts. The air duct outlets in the intercity vehicle driver's cab are relatively small, and the wall panels and cover panels are formed into complex shapes. The existing air duct and air outlet structure cannot clean the inside of the air duct even if the air outlet is disassembled, especially the upper air outlet structure. Because the air outlet is facing upward, the inside of the air duct is prone to various solid and liquid garbage, and it is impossible to clean it thoroughly, which affects the air outlet effect, air quality, and equipment service life. Summary of the invention

[0003] In order to solve the above problems, the utility model provides an easy-to-clean air outlet structure for rail vehicles, which can remove the air outlet individually or the air outlet module as a whole.

[0004] The utility model discloses an easy-to-clean air vent structure for a rail vehicle, comprising a wall panel body, an air outlet, an air outlet clamping plate, a cover plate, and a buckle; the wall panel body is provided with a closed air cavity at the air duct, and the wall panel surfaces around the air cavity are lower than the main wall panel surface, forming a step-type structure; the shape of the cover plate is consistent with the shape of the lower wall panels around the air cavity, the thickness of the cover plate is equal to the step height between the wall panels around the air cavity and the main wall panel surface, and the cover plate is fixedly connected to the wall panel body by a buckle; one end of the cover plate close to the air cavity is fixedly connected to the air outlet clamping plate in the entire circumference; the air outlet is arranged at the opening of the air cavity, and a buckle is provided circumferentially at the outer end of the air outlet, and the air outlet is fixedly connected to the air outlet clamping plate by the buckle.

[0005] Furthermore, the air outlet is an adjustable air outlet.

[0006] Furthermore, there are three air outlets, which are arranged in parallel horizontally.

[0007] Furthermore, the cover plate and the air outlet clamping plate are bonded.

[0008] Furthermore, the gap between the cover plate and the wall panel body is 2 mm.

[0009] Furthermore, the wall panel body is made of glass fiber reinforced plastic composite material.

[0010] The easy-to-clean air outlet structure for rail vehicles described in the utility model can not only disassemble the air outlet separately but also disassemble the air outlet module as a whole. The cover plate can be disassembled as a whole with the air outlet. After disassembly, the air cavity can be directly cleaned by hand, thereby thoroughly cleaning the air cavity.

[0016] Combine the following Figures 1 to 3 The easy-to-clean tuyere structure for a rail vehicle of the utility model is described in detail.

[0017] like Figures 1 to 3 As shown, the easy-to-clean air outlet structure for rail vehicles of the utility model comprises a wall panel body 1, an adjustable air outlet 3, an air outlet clamping plate 5, a cover plate 2, and a buckle 4.

[0018] The wall panel body 1 is made of a glass fiber reinforced plastic composite material, and a closed air cavity 8 is provided at the air duct 7. The air cavity 8 is connected to the air duct 7, and the wall panel surface around the air cavity 8 is lower than the main wall panel surface, forming a step-type structure.

[0019] The shape of the cover plate 2 is consistent with the shape of the lower wall panels around the air cavity 8. The thickness of the cover plate 2 is equal to the step height between the wall panels around the air cavity and the main wall panel surface. The cover plate 2 is fixedly connected to the wall panel body 1 by the buckle 4. The gap between the cover plate 2 and the wall panel body 1 is 2 mm, which serves as a disassembly gap.

[0020] An air outlet clamping plate 5 is bonded to one end of the cover plate 2 near the air cavity 8 along the entire circumference.

[0021] There are three adjustable air outlets 3, which are arranged in parallel transversely at the opening of the air cavity 8. Buckles are provided at the outer ends of the adjustable air outlets 3 along the circumferential direction, and the adjustable air outlets 3 are fixedly connected to the air outlet clamping plate 5 through the buckles.

[0022] The easy-to-clean air outlet structure for rail vehicles of the utility model can be used to disassemble the air outlet separately or the air outlet module as a whole. The cover plate can be disassembled as a whole with the air outlet, and after disassembly, the air cavity can be directly cleaned by hand, thereby cleaning the air cavity.
