Description

DEVICE FOR VENTILATION OF THE BATTERY BOX

Technical field

The useful model relates to ventilation and can be used for exhaust ventilation of a vehicle.

A device for ventilating a battery box of a car 1 is known, comprising a ventilation pipe attached to a battery box with a shield placed under it and a casing covering the pipe end to form an annular gap. The exhaust pipe is located at an angle to the battery box, and its end and shield are made elliptical. The shield is installed in relation to the end of the pipe with a gap. The pipe outlet and the shield from below are covered by a casing.

A disadvantage of the known device 1 is the lower location of the casing, which allows the penetration of dust particles into the ventilation device and inside the battery box, which reduces operational reliability.

Utility Model Essence

The basis of this utility model is the task of creating a device for ventilation of the battery box of a car, which has greater reliability.

State of the art

The solution to this problem is achieved by the fact that in the device for ventilation of the battery box of the car, containing an exhaust pipe attached at an angle to the battery box, provided with a shield and a casing covering the elliptical end of the pipe with the formation of a gap, according to a useful model, the angle of inclination of the pipe to the battery box is made so that the ellipsoobrazny pipe section is located horizontally and is facing upwards, the shield and casing are made cylindrical and fixed at the top above the ellipsoidal pipe section, while the axis the cylindrical generatrices of the shield and the casing are located vertically, and the casing covers the shield and the pipe inlet from above.

The introduction of the above distinguishing features in a utility model reduces the possibility of dust particles entering the battery box, thereby increasing the reliability of the device.

Brief Description of the Drawings

The essence of the utility model is illustrated by the drawings shown in FIG. 1,2. In FIG. 1 shows the described device, a General view, figure 2 is a view along section AA in FIG. 1.

With reference to FIG. 1, 2 are indicated:

1- battery box;

2- vent pipe

3- shield;

4- casing;

5-ring gap;

6- clearance.

The best option for implementation

The proposed device for ventilation is installed on the battery box 1, mounted under the floor of a railway carriage. An exhaust pipe 2 is attached at an angle a to the side wall of the battery box 1. The angle of inclination of the pipe a to the battery box is made so that the pipe is attached to the battery box} so that the ellipse-shaped cut of pipe 2 is horizontal and facing up (compared to the prototype, the pipe is deployed 180 °, and the angle a 180 ° - a). A flap 3 connected to the casing 4 is located above the ellipse-shaped cut in the outlet of the pipe 2. The shield 3 is made cylindrical and installed in such a way that it covers the elliptical end of the pipe 2 with the formation of a gap 5 of variable cross section. The shield 3 and the casing 4 are rigidly interconnected, mounted at the top above the ellipsoid section of the pipe 2 and fixed, while the axis of the cylindrical generatrix of the shield 3 and the casing 4 is located vertically, and the casing 4 covers the shield 3 and the pipe inlet 2 from above. The casing 4 is installed in relation to the end of the pipe 2 with a reduced clearance 6.

The device operates as follows.

Ventilation of gases from the battery box 1 during the movement of the car is carried out under the action of natural vacuum inside the shield 3. From the pipe 2 through the gap 6 gases are discharged along the annular gap 5. During the movement of the vehicle, under the floor of which there is a battery box 1 with a ventilation device, turbulences are formed carrying particles of dust, snow, etc. These particles from the surface

Device operation

devices are carried away by a counter flow of air. The penetration of these particles into the internal volume of the box 1 is prevented by the upper arrangement of the casing 4 with respect to the inlet of the pipe 2 and the clearance 6 reduced in height.

Due to the upper arrangement of the skin} ha, dust particles do not clog the gap 6 over time and do not interfere with the ventilation process.

Thus, the introduction of distinctive features in the proposed utility model allows us to solve the problem - to increase the reliability of the device for ventilation of the battery box of the car.

Industrial prsh "Enimost

The present invention is developed at the level of working drawings and prototypes. Tests are carried out and serial development is being prepared. Prototypes made. Positive results were obtained during the operation of prototype cars.
