Detailed Description

In order to better understand the purpose, structure and function of the present invention, a corrugated floor drainage structure for a motor train unit will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 to 2, the drainage structure of the corrugated floor 1 of the motor train unit comprises the corrugated floor 1, a drainage tank 2, a heat tracing device 3 and a drainage valve 4.

Referring to fig. 3 to 4, the drainage channel 2 includes channel iron 201, a bottom cover plate 202, a reinforcing rib plate 203, and an end cover plate 204 of the drainage channel 2.

Referring to fig. 1 to 8, thirty-two circular holes are formed in the upper part of the channel iron 201 and correspond to the thirty-two circular holes formed in the wave troughs of the corrugated floor 1, and are used for receiving condensed water collected by the corrugated floor 1 from a vehicle body structure; the diameter of an opening hole of the corrugated floor 1 is larger than that of an opening hole at the upper part of the channel iron 201, and the circumference of a circular hole at the wave trough of the corrugated plate is welded to ensure that the corrugated plate and the drainage channel 2 are sealed; the channel iron 201 is reversely buckled on the bottom sealing plate 202 and is connected with the bottom sealing plate 202 in a welding mode, the space enclosed by the channel iron 201 and the bottom sealing plate 202 is a drainage channel 2, and two ends of the drainage channel 2 are connected with the end sealing plates 204 in a welding mode. And a reinforcing rib plate 203 is arranged at the connecting part of the bottom sealing plate and the channel iron and used for increasing the strength of the drainage channel. The end sealing plate 204 of the drainage channel 2 seals the end of the drainage channel 2 to seal the drainage channel 2, so that the drainage structure is isolated from the external environment and is used for collecting condensed water.

Mounting holes are reserved on two sides of the bottom sealing plate 202 and used for mounting the interface of the heat tracing device 3 and the drain valve 4, and the drain valve 4 is mounted at the position of the large round hole 205 of the bottom sealing plate 202, so that the drain tank 2 is communicated with the drain valve 4; the two sides of the drain valve 4 are respectively provided with a heat tracing device 3. The bottom sealing plate 202 is connected with the heat tracing device 3 and the water drain valve 4 through bolts, and a rubber pad needs to be installed when the heat tracing device 3 and the water drain valve 4 are installed so as to ensure the sealing performance of the connecting structure. Condensed water of the corrugated floor 1 enters the drainage groove 2 and is temporarily stored in the drainage groove 2; after the train reaches the designated position, the condensed water is discharged through a drain valve 4 installed at the lower part of the drain tank 2. The heat tracing device 3 is used for solving the problem that the drain hole can be frozen in a cold environment.

The installation mode and the heating principle of the heat tracing device 3 are as follows: the heat tracing device 3 is of a long strip structure, is parallel to the water drainage groove 2, and is arranged below the water drainage groove 2 through two rows of bolts with 20 bolts, wherein the water drainage groove 2 is provided with a reserved mounting hole for mounting the heat tracing device 3. The heat tracing device 3 belongs to 'self-control' heat tracing, and after the power supply is switched on, the polymer semiconductor wire core inside the heat tracing device can automatically adjust the resistance along with the change of the ambient temperature. When the ambient temperature rises, the resistance value is increased, the current is reduced, and the heating power is reduced; when the ambient temperature decreases, the resistance value decreases, the current increases, and the heat generation power increases.
