Description

Technical Field

[0001] The invention belongs to the technical field of rail vehicle body structures, and in particular relates to a drainage structure of a corrugated floor of an EMU. Background Art

[0002] Comfort is an important indicator of rail train performance, and train noise is one of the important factors affecting train comfort. With the improvement of train noise requirements, the requirements for car body sealing are also getting higher and higher. Existing corrugated floor steel body trains use a method of drainage in the corrugated floor area by opening drainage holes at each corrugated plate trough so that condensed water can be discharged to the train line area at any time. This structure makes the car body connected to the outside world at the drainage holes, which cannot meet the increasingly high requirements for car body sealing. At the same time, condensed water can be discharged at any time, and the time and place of its discharge cannot be controlled, which is not friendly to the environment; the drainage holes of this structure have the risk of freezing in cold environments. In order to solve the problems related to car body sealing requirements, freezing of drainage holes in cold environments, and environmental friendliness, a new type of corrugated floor drainage structure is designed. Summary of the invention

[0004] To achieve the above-mentioned purpose of the invention, the present invention provides a drainage structure of a corrugated floor of an EMU, characterized in that it includes a corrugated floor, a drainage trough, a heating device and a drainage valve; the drainage trough includes a channel iron, a bottom sealing plate, a reinforcing rib plate, and a drainage trough end sealing plate, a plurality of holes are opened in the upper part of the channel iron corresponding to the trough of the corrugated floor and are fixedly sealed and connected, the channel iron is inverted on the bottom sealing plate and is fixedly sealed and connected thereto, the channel iron and the bottom sealing plate enclose a space as the drainage trough, the two ends of the drainage trough are fixedly sealed and connected to the end sealing plates, a large circular hole is provided on the bottom sealing plate, and the large circular hole is fixedly connected to the drainage valve.

[0005] Furthermore, a plurality of holes are opened in the upper part of the channel iron corresponding to the troughs of the corrugated floor, wherein the diameter of the openings in the corrugated floor is larger than the diameter of the openings in the upper part of the channel iron.

[0006] Furthermore, a reinforcing rib plate is provided at the connection position between the bottom sealing plate and the channel iron.

[0007] Furthermore, it also includes a heating device, which is a long strip structure, parallel to the drainage groove and fixed below it.

[0022] In order to better understand the purpose, structure and function of the present invention, a drainage structure of a corrugated floor of an EMU of the present invention is further described in detail below in conjunction with the accompanying drawings.

[0023] Reference Figure 1 to Figure 2 The drainage structure of the EMU corrugated floor 1 includes a corrugated floor 1, a drainage trough 2, a heating device 3 and a drainage valve 4.

[0024] Reference Figure 3As shown in FIG. 4 , the drainage trough 2 includes a channel iron 201 , a bottom sealing plate 202 , a reinforcing rib plate 203 , and a sealing plate 204 at the end of the drainage trough 2 .

[0025] Reference Figures 1 to 8 , there are thirty-two circular holes on the upper part of the channel iron 201 corresponding to the thirty-two circular holes on the trough of the corrugated floor 1, which are used to receive the condensed water collected by the corrugated floor 1 from the vehicle body structure; the diameter of the opening of the corrugated floor 1 is larger than the diameter of the opening of the upper part of the channel iron 201, and the corrugated plate trough The circumference of the circular hole is welded to ensure the seal between the corrugated plate and the drainage groove 2; the channel iron 201 is inverted on the bottom sealing plate 202 and welded to the bottom sealing plate 202. The space enclosed by the channel iron 201 and the bottom sealing plate 202 is the drainage groove 2, and the two ends of the drainage groove 2 are welded to the end sealing plate 204. A reinforcing rib plate 203 is provided at the connection between the bottom sealing plate and the channel iron to increase the strength of the drainage groove. The end sealing plate 204 of the drainage groove 2 blocks the end of the drainage groove 2 to seal the drainage groove 2, so that the drainage structure is isolated from the external environment, and is also used to collect condensed water.

[0026] There are installation holes on both sides of the bottom cover plate 202 for installing the interface of the heating device 3 and the drain valve 4. The drain valve 4 is installed at the position of the large circular hole 205 of the bottom cover plate 202, so that the drain trough 2 is connected with the drain valve 4; the heating device 3 is installed on both sides of the drain valve 4. The bottom cover plate 202 is connected with the heating device 3 and the drain valve 4 by bolts. When the heating device 3 and the drain valve 4 are installed, rubber pads need to be installed to ensure the sealing of the connection structure. The condensed water of the corrugated floor 1 enters the drain trough 2 and is temporarily stored in the drain trough 2; after the train arrives at the designated position, the condensed water is discharged through the drain valve 4 installed at the bottom of the drain trough 2. The heating device 3 is used to solve the problem that the drain hole may freeze in a cold environment.

[0027] Installation method and heating principle of heating device 3: heating device 3 is a long strip structure, parallel to drain trough 2, and is installed under drain trough 2 through two rows of about 20 bolts, where drain trough 2 has reserved installation holes for installation of heating device 3. Heating device 3 is a "self-controlled" heating device. After the power is turned on, the polymer semiconductor core inside it will automatically adjust the resistance as the ambient temperature changes. When the ambient temperature rises, the resistance value increases, the current decreases, and the heating power decreases; when the ambient temperature decreases, the resistance value decreases, the current increases, and the heating power increases.
