Description

Urban rail vehicle is equipment rain water separator under car

Technical Field

The utility model relates to an equipment box field under the railway vehicle especially relates to an urban rail vehicle is equipment rain water separator under car.

Background

Before the invention of the utility model, the equipment under and on the high-speed rail motor car and urban rail vehicle sometimes involves the module of high calorific capacity, so the device can not be designed into the airtight state, needs the outside air to get into the supplementary module heat dissipation in the equipment. Because of this, when meeting rainy weather, a large amount of rainwater can directly get into in the equipment, leads to the device short circuit etc. to influence vehicle normal operating, and more serious condition can arouse the conflagration, seriously threatens driving and passenger life safety.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming above-mentioned defect, research one kind city rail vehicle is equipped with rain water separator under the car.

The technical scheme of the utility model is that:

the rainwater separation device for the equipment under the urban rail vehicle is mainly technically characterized in that an edge frame is a cylinder, the inner front part of the edge frame is vertically connected with a flow guide pipe, vertical filter pipes are staggered behind the flow guide pipe, a water leakage groove is arranged below the edge frame, and a water baffle is connected below the rear part of the edge frame.

The left inner side and the right inner side of the rear part of the side frame are connected with an F-shaped groove pressing plate, and the filter screen is vertically inserted into the F-shaped groove pressing plate and is positioned behind the filter pipe.

The lower part of the filter pipe is communicated with the water leakage groove through a slope.

The lower surface of the rear part of the side frame is connected with a water baffle to form a closed groove.

The utility model discloses an effect and advantage lie in utilizing honeycomb duct and chimney filter staggered arrangement to block inside the rainwater gets into the box, utilize the rainwater discharge box that the side frame lower part 10 surely connects the water leakage groove to block, filtering large granule dust through the filter screen to guarantee that the rainwater can't get into the box, and the air can normally circulate. The diversion pipes and the filter pipes are arranged in a staggered manner, so that the thickness of the whole rainwater separation device can be greatly reduced, and the volume of a product is smaller; the filter screen and the rainwater separation device are installed in a slot type, so that the filter screen and the rainwater separation device can be conveniently detached, replaced and maintained; side frame has about mistake proofing function with box complex mounting hole, controls the fixed orifices and is not on same water flat line, if upside down, will unable the installation, ensures can not because of the installation direction mistake, leads to the unable normal work of rainwater separator. Aiming at the current situations that equipment under an urban rail vehicle needs heat dissipation and ventilation, a corresponding rainwater separation device is designed, and under the condition that the equipment needs ventilation and heat dissipation, rainwater is enabled to be isolated from the equipment and air circulation is guaranteed in rainy days, and potential safety hazards caused by rainwater entering the equipment are eliminated.

The utility model discloses simple structure, it is small, with low costs, the operation is also simple.

The part names corresponding to the reference numbers in the figures are as follows:

the rainwater separation device comprises a rainwater separation device I, a side frame 1, a water leakage groove 2, a flow guide pipe 3, a filter pipe 4, a filter screen 5, a water baffle 6, an F groove pressure plate 7 and a sealing rubber pad 8.

Detailed Description

As shown in fig. 1, 2, 3, and 4:

a water leakage groove 2 is formed below a side frame 1, a row of guide pipes 3 are vertically welded at the front part in the

side frame

1, 2 rows of filter pipes 4 are vertically arranged behind the guide pipes 3 in a staggered mode, the filter pipes 4 are connected with the bottom of the side frame 1, the bottom of the side frame 1 is connected with the water leakage groove 2 through a 10-degree slope, F groove pressing plates 7 are welded on the left inner side and the right inner side of the rear part of the side frame 1, water blocking plates 6 are welded below the rear part of the side frame 1 to form a closed groove, a filter screen 5 is vertically inserted into the F groove pressing plates 7 and is tightly attached to the rear part of the filter pipes 4, and a sealing rubber pad 8. The whole material is aluminum alloy.

A row of honeycomb ducts 3 can play the guide effect to the rainwater, makes the rainwater can only pass through from the clearance between honeycomb duct 3. The cross section of the filter pipe 4 is in a non-closed ring shape and is distributed in the gap of the draft tube 3, so that the rainwater guided by the draft tube can be filtered into the water leakage groove 2. The filter screen 5 can filter large-particle dust. The water baffle 6 can play a role in temporarily stopping rainwater which is accumulated to be not more than 40mm high from entering the equipment when the rainfall is too large and cannot be discharged through the water leakage groove 2 in time. Because the side frame 1 and the box body have a gap when being installed, in order to prevent rainwater from entering the box body from the periphery, the sealing rubber gasket 8 is required to be extruded to play a role in water prevention and dust prevention. Side frame 1 has about error proofing function with box complex mounting hole, controls the fixed orifices and is not on same water flat line, if upside down, will unable the installation, ensures can not because of the installation direction mistake, leads to the unable normal work of rainwater separator.

The utility model discloses application process brief explanation as follows:

firstly, rainwater hits a first drainage guide pipe 3, and can only pass through gaps between every two drainage guide pipes 3 after being blocked and reaches a second drainage filter pipe 4, most of rainwater can collide the inner side of the filter pipe 4 and flow to a water leakage groove 2, the water leakage groove 2 is inclined at an angle of 10 degrees with the horizontal plane, the rainwater can be drained from the water leakage groove 2 under the action of gravity, after being filtered by two layers, a small amount of rainwater can enter a third layer of filter pipe 4, the same as the second layer of filter pipe 4, and finally the filtered rainwater can flow into the lower water leakage groove 2 along the filter pipe 4 and be drained out, when the rainfall is large, the rainwater cannot be drained out from the water leakage groove 2 in time, and a water baffle 6 can block rainwater accumulated at a height of 40mm, so that the rainwater cannot enter equipment directly; air can enter the box body through the gaps between the draft tubes 3 and the gaps between the filter tubes, and large-particle dust and mosquitoes in the air can be blocked when passing through the filter screen 5. Thereby realizing the function of rainwater separation

The utility model discloses install under the urban rail vehicle car on the equipment, can carry out the rainwater separation effectively, guarantee that the equipment operation is reliable and stable under the car.
