Description

Filter screen for high-speed rail vehicle

Technical Field

The utility model belongs to the technical field of the filter screen, especially a simple to operate, simple structure, have from the filter screen that is used for high-speed railway vehicle of cleaning function.

Background

Routine inspection of the motor train unit finds that: the prior skirting board filter screen is often blocked, the filtering function is weakened or lost, and the ventilation and cooling functions of an internal charging unit are weakened and lost. Therefore, the monitoring system can automatically alarm or the transformer has operation faults, and the potential safety hazard of driving is formed. At present, a filter screen used for factory loading is similar to a screen window in the field of life, the meshes of the filter screen are easily blocked by sundries, and the filtering effect is reduced or lost. The filter screen intensity is not high, and the filter screen damage and be inconvenient to wash can be caused to the external force slightly bigger in the cleaning process. Based on the phenomena, each motor train section on the whole road seeks a novel high-performance, safe and reliable filter screen convenient to clean so as to change the current passive state.

To solve this problem, patent No. 201821702262.2, with patent name: EMUs skirtboard filter screen, the patent provide a neotype filter screen, be convenient for clean. But the self-cleaning function cannot be realized.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-4, the filter screen for high-speed rail vehicles according to the structure of the present invention comprises support bars 1 arranged at intervals, and a plurality of filter wires 2 with wave shapes welded on the support bars; the cross section of the filter wire is triangular, and one corner of the triangle is welded with the support bar; the section of the support bar is rectangular, and the middle part of the upper surface of the rectangle is provided with a protrusion 3 matched with the filter wire; the protrusions are arc-shaped, triangular or trapezoidal.

Preferably: the filter wires are perpendicular to the support bars and are evenly distributed along the support bars.

Preferably: the filter screen is rectangle, and the shrouding 4 of "L" shape is welded to the both sides (specifically the left and right sides in figure 1) of filter screen for fix the filter screen on the automobile body. This shrouding is relative current shrouding of falling "L" shape, and firmness that can effectual improvement is fixed can also reduce the risk that the filter screen warp simultaneously. According to the shape of the ventilation opening for installing the filter screen, the upper side and the lower side are usually positioned in the ventilation opening (within the thickness range), and if necessary, the upper side and the lower side of the filter screen can be welded and fixed with sealing edges to prevent wind or impurities from entering from the upper side and the lower side.

Preferably: the cross section of the filter wire is an isosceles triangle, and the vertex angle is welded and fixed with the supporting bars.

Preferably: the material of the filter wires and/or the support bars is stainless steel 304-316 series.

Preferably: the gap between two adjacent filter wires is 0.02-5 mm.

Preferably: the waveform is a sine waveform or a trapezoidal waveform.

The use process of the utility model is illustrated by the apron board as an example:

the structure of the utility model is arranged on the apron board at the lower side of the motor train unit body to ensure the ventilation and heat exchange between the equipment and the outside; the shape and the size of the apron board grid filter screen are matched with the apron board filter screen slot of the target motor train unit, the height of the wave shape is the same as the width of the slot, and finally the apron board filter screen is placed into the slot.

After the structure is installed, foreign matters such as catkin are blocked outside along with the running of a vehicle, and when the foreign matters are attached to or adsorbed on the outer side of the filter screen, the structure has the function of self-cleaning. The specific principle is that when a vehicle runs at a high speed, air flows at a high speed outside the filter screen to form wind, the wind flows at a high speed outside two wave crests of the wavy filter screen to form a low-pressure belt at the wave trough position, and impurities are sucked out to form self-cleaning; in addition, wind can enter from the gap of the filter screen on the windward side and blow out from the leeward side, and the filter wires are in an inverted triangle shape, so that the gap on the outermost side is minimized, so that sundries are difficult to blow into the filter screen by the wind, the sundries attached to the outer side of the filter screen are easy to blow away, and the sundries on the outer side of the windward side can move forwards and separate from the filter screen under the action of the wind, thereby ensuring the cleanness of the filter screen. The structure has a symmetrical structure, and is suitable for forward and reverse running of a train, namely, the structure has good effect on both forward wind and reverse wind.

In addition, the structure also has the advantages of simple structure, low cost and convenient installation.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
