Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of rail transit accessories, and more specifically, relates to a filtering shutter for rail transit. Background Art
[0002] The operating environment of rail transit vehicles is generally harsh, especially for engineering vehicles such as rail grinding trains, which will generate a lot of iron filings or dust during operation. Therefore, the dust resistance of the vehicle body is particularly important. Taking the rail grinding train as an example, a lot of heat is generated in the engine and generator room during operation, and windows need to be opened for heat dissipation. When the train is running, iron filings and dust splash outside the vehicle, which can easily enter the engine and generator room through the heat dissipation windows, causing pollution to the engine and generator, affecting the normal operation of the train. Therefore, the heat dissipation windows need certain dustproof and heat dissipation performance, and most of them use shutters. The dustproof performance of existing shutters is not enough to meet the conditions of use, and most of the shutters with filtering structures are integrated structures. The replacement of the internal filtering structure is extremely inconvenient, and if the entire structure is replaced, the cost is high. Summary of the invention
[0003] The purpose of the present invention is to provide a filtering shutter for rail transit in view of the deficiencies in the prior art, which has a frame that is easy to disassemble and assemble and a protective cover that is easy to open.

[0024] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.
[0025] The present invention provides a filter shutter for rail transit, comprising:
[0026] A frame, wherein a window is provided inside the frame, and a plurality of shutters are arranged in the window;
[0027] A shield is arranged on one side of the frame, one side of the shield is rotatably connected to the frame through a hinge, and the other side of the shield is provided with a buckle that matches the frame;
[0028] The filter medium is arranged between the louver and the shield.
[0029] Specifically, the shutter is installed on the vehicle body through a frame, which is easy to install. The filter medium is fixed in the frame through a protective cover. The protective cover can be closed and opened by a buckle. The opened protective cover can be rotated by a hinge to facilitate the removal of the internal filter medium for cleaning or replacement. It is easy to use and saves costs.
[0030] In other examples, the hinge may also be configured as a snap-fit structure, and the shield may be removed by opening the snaps on both sides of the shield, thereby facilitating cleaning or replacement of the internal filter medium.
[0031] In one example, a plurality of mounting feet are disposed on the outer side of the frame, and mounting holes are formed on the mounting feet.
[0032] Specifically, the frame is installed in cooperation with the vehicle body through the mounting feet and the mounting holes, and is easy to install and highly adaptable. During installation, a rubber pad is placed between the vehicle body and the mounting feet to achieve a sealing and dustproof effect.
[0033] In one example, a flange is provided in the window of the frame toward the shield.
[0034] Specifically, the flange arrangement can form a cavity structure between the louver and the shield, which is convenient for placing the filter medium.
[0035] In one example, a filter is installed inside the flange near the louver, and the shape of the filter matches the internal size of the flange.
[0036] Specifically, the filter screen is installed close to the louver, which can limit the filter medium, prevent the filter medium from leaking out from the gap between the louver, and improve the protection effect.
[0037] In one example, the shield includes a shield frame matched with the flange, and a filter is arranged in the shield frame.
[0038] Specifically, the filter screen inside the protective cover and the filter screen attached to the inner side of the louver fix the filter medium in place and improve the filtering effect.
[0039] In one example, a plurality of process nail holes are formed on the shield frame, and process nails are arranged in the process nail holes.
[0040] Specifically, the setting of the process nails can play a role in positioning the filter medium when the filter medium is placed, and the filter medium is misplaced when the protective cover is closed.
[0041] In one example, the filter medium is made of coconut fiber.
[0042] In other examples, the filter medium may also be filter cotton.
[0043] Specifically, the filter medium can effectively prevent moisture and has good ventilation effect. It can effectively prevent dust and impurities from entering the car and will not cause negative pressure in the car.
[0044] In one example, the louvers and the frame are welded into an integrated structure.
[0045] In one example, a reinforcement frame facing the frame direction is arranged on the outer side of the shield frame, and the reinforcement frame is wrapped around the outer side of the flange.
[0046] Specifically, the provision of the reinforcement frame can improve the strength of the shield, and prevent the shield from being deformed due to vibration when the train is running, which would cause the dustproof effect of the shutter to deteriorate.
[0047] In one example, the filter material is a perforated steel plate.
[0048] In other examples, the filter screen may also be a stainless steel wire screen or an aluminum alloy screen.
