Abstract

The air intake device of the vehicle, can be used, in particular, on railway cars for supplying air to their power units, contains an air duct (1), in the wall (2) of the duct (3) of which a receiving hole (4) is formed, blocked by a grill (5) . Inside the box (3), a shutter (6), pivotally mounted on the wall (2) above the inlet opening (4), is made in the form of a plate of elastic material. From the inside, a rod (9) is rigidly attached to the shutter (6), to which a lever (11) is attached with a hinge (10) with a handle (13) at the end withdrawn from the box (3). To lock the lever (11), and therefore the shutter (6) in the open and closed positions, the figured grooves (14) are made on the lever (11), and mating protrusions are formed on the wall (12) of the box (3), for example, in the form of brackets (15) and (16). The device is simple, reliable, has small overall dimensions and weight and allows you to quickly and conveniently rotate the shutter (6) from the vehicle’s premises.

Description

The utility model relates to devices for intake and supply of air to the units of vehicles and can be used on railway and other modes of transport, in particular, on railway cars for intake and supply of air into the ventilation system, to power units, for example, diesel generators, located in containers in the car space [1].

A diesel generator located in a sealed and thermostatically controlled container is used, as a rule, during the parking of the train in the absence of external power sources at this place. In other cases, it does not turn on and at this time the air intake (and with it dust and moisture) must be stopped, for which the air intake must be sealed.

It is already known an air intake device of a locomotive diesel cooling system containing an air duct, in one of the walls of the duct of which there is a receiving opening blocked by a grill, and a rotary damper located inside the air duct of the duct, blocking the receiving hole when the diesel is idle [2].

It is also known air intake device of the vehicle, containing an air duct, in one of the walls of the box which is formed receiving

a hole, and a rotary damper located inside the duct duct, blocking the receiving hole by means of a linkage mechanism, with a manual drive [3].

The hinged-lever mechanism provides movement of the damper from the passenger compartment with its fixation in the open and closed positions, however it is structurally complicated, takes up a lot of space in the duct and has a significant mass.

The technical result that can be obtained by implementing the claimed utility model is to simplify the design of the mechanism for moving the shutter, reducing its mass and overall dimensions, increasing the reliability of its operation while ensuring remote movement of the shutter from the vehicle’s premises.

This result can be achieved due to the fact that in the air intake device containing the air duct, in one of the walls of the duct of which there is a receiving hole blocked by a grill and a damper located inside the duct duct, pivotally mounted on the duct wall above the inlet, it is proposed to the damper with its internal of the side facing the inside of the box, rigidly attach at one end a rod, the second end of which is pivotally connected to the lever ending through the box wall, ending with the handles first and provided with stoppers extended and retracted positions in the box.

For a dense and reliable overlap of the inlet, the damper is proposed to be made in the form of a plate of elastic material with a flange formed around its perimeter.

The stoppers of the retracted and extended positions of the lever can be made in the form of shaped grooves formed on the lever, interacting with the mating protrusions fixed to the box wall, and the lever can be passed through the box wall through a window formed in it, along the perimeter of which an elastic seal in contact with the lever is fixed and flexible material.

A possible structural implementation of the claimed utility model is illustrated in the accompanying drawings.

Figure 1 - shows the air intake device (side view).

Figure 2 is a top view, section aa.

Figure 3 is a rear view, section bB.

Figure 4 is a side view with a shutter in the open position

Figure 5 is a cross-section EE in figure 1.

The air intake device of the vehicle contains an air duct 1, in the wall 2 of the box 3 which is formed a receiving hole 4, overlapped by the grill 5.

Inside the box 3 is a shutter 6, made in the form of a plate of elastic material with a flange 7 around its perimeter. The damper 6 is mounted on the wall 2 of the box 3 above the receiving hole 4 by means of a hinge 8.

A rod 9 is rigidly attached to the inner side of the shutter 6, to the end of which a lever 11 is connected through the hinge 10, passing through the wall 12 of the box 3.

At the end of the lever 11, located outside the box 3, a handle 13. is fixed. The lever 11 is locked in two positions: in the extended position, when the receiving hole 4 is open (Fig. 4) and in the retracted when the shutter 6 overlaps the receiving hole 4. For this, on the lever 11, figured grooves 14 are made, and mating protrusions are formed on the wall 12, for example, in the form of brackets 15 and 16.

For the passage of the lever 11 through the wall 12, a window 17 is formed in it, in which a seal 18 in contact with the lever 11 is fixed along its perimeter (Fig. 5). The seal 18 may be made of an elastic material, for example, rubber with a slot 19.

In the closed position, the shutter 6 is pressed against the wall 2 of the duct 3 and, thanks to the flanging 7 and its own elasticity, provides sealing of the duct 1.

To open the receiving hole 4 (before starting the diesel generator), the lever 11 is unlocked by turning it to release the bracket 16 from the groove 14 (Fig. 3) and pulling the lever 11 by the handle 13, which leads to the rotation of the shutter 6 relative to the hinge 8.

In the open position of the shutter 6, the lever 11 is locked by turning it until the bracket 15 fixed on the wall 12 enters the figured groove 14 on the lever 11.

The inventive mechanism for moving the shutter 6 is simple, reliable in operation, takes up little space in the duct 1 and has a small mass and

this ensures the rapid movement of the shutter 6 from the premises of the vehicle.
