Abstract

The essence of the invention: the device comprises an exhaust pipe of a vehicle, a gas receiving receiver connected to it by a branch pipe in the form of an elastic and hermetic container. The capacity of the gas receiver is made with the possibility of accumulation of exhaust gases and is fixed on the vehicle. 1 hp f-ly, 1 ill.

Description

The invention relates to devices for preventing the spread of exhaust gases of vehicles and is intended to provide sanitary and hygienic working conditions when a mobile source of exhaust gases is operating in a confined or poorly ventilated space, in particular, in garages, warehouses, workshops, etc.

A device for removing gases emitted from an exhaust pipe of a motor vehicle is known, which contains a pipe connected to the exhaust pipe of a motor vehicle and an exhaust air duct with a blocked longitudinal slit.

It is also known to have a device in a locomotive depot for trapping and expelling smoke from a locomotive introduced into the depot, containing a pipe in the form of a harmonic, the free end of which is lowered to the line of movement of the pipe of a locomotive in order to capture the harmonic by this pipe.

This device limits the maneuverability of the vehicle, in addition, to ensure the capture of the pipe by the engine of the gas receiver pipe at the entrance to the depot and release from this pipe during

The exit from the depot, the internal diameter of the gas receiver pipe must be larger than the diameter of the steam locomotive pipe, and the gap between the locomotive pipe and the gas receiver pipe will reduce the degree of flue gas localization.

Therefore, both of these solutions do not allow solving the problem of moving a vehicle from an internal combustion engine, for example, in workshops and warehouses where it is required to make turns and other maneuvers, which will significantly complicate the laying of the duct main and prevent leakage from the duct of exhaust gases.

The aim of the invention is to provide vehicle maneuverability and increase the degree of localization of exhaust gases.

The goal is achieved by the fact that in a device for exhaust gas removal of a vehicle containing a flexible pipe connected to the exhaust pipe of a vehicle and a gas receiver equipped with a valve, the gas receiver is designed as a movable hermetic flexible or elastic tank. Gas receiver can also be made

It is not in the form of separate containers interconnected through flexible nozzles. In addition, the gas receiver or its separate tanks can be mounted either on the vehicle body or on the trailer.

The invention is illustrated in the drawing.

A vehicle exhaust system comprises a car body 1, a gas receiver 2 for exhausted gases, made in the form of a hermetic and flexible or elastic container (for example, from rubberized canvas, tarpaulin, etc.) and communicated with the exhaust pipe of the car through a flexible pipe 3. The car can also be equipped with a single or two-axle trailer 4, on which an additional gas receiver 5 is attached, connected by means of a flexible pipe 8 to the coupling 7. Hermetic flexible or electric cal container 2, 5 may be formed with corrugated walls and prigruzami 8. In addition, the gas inlet 2, 5 is provided with a safety valve 9.

The device works as follows.

Before entering a room in which there is no ventilation or its implementation is difficult, for example, in a workshop or a warehouse room, a flexible pipe 3 is attached to the exhaust pipe of the car and the exhaust gases from the internal combustion engine of the car pass through pipe 3 to the gas receiver 2 and accumulate there because the rubberized canvas shell prevents exhaust gases from escaping.

Thus, the proposed device allows localization of exhaust gas emissions and provides movement of the gas receiver with the vehicle.

When leaving the non-ventilated area, the flexible pipe 3 is disconnected and the waste gases accumulated in the gas receiver 2 are discharged into the atmosphere. In order to increase the useful volume of the gas receiver 2, its capacity can be made in the form of several separate containers interconnected by flexible nozzles and fixed on all sides of the car body, which allows an increase in the travel time of the car from the unventilated area. But in this case, the width of the car may increase significantly, which may make it difficult to maneuver it in the warehouse. Therefore, it is more expedient to attach a one- or two-axle trailer 4 to the car, or several trailers on whose cargo platform to place gas receivers 5 communicated with each other through flexible pipes 6 and coupling sleeves 7, one of the gas receivers being connected either to the gas receiver 2 or to the exhaust pipe car.

In the upper part of the gas receiver 5, weights 8, for example, a steel sheet can be fixed, and the walls of the container can be made with corrugations, which will facilitate the removal of exhaust gases from the gas receiver 5. The emergency valve 9 installed in the wall of the gas receiver 2.5 opens when creating excess pressure of the exhaust gases inside the gas receiver.

The application of the proposed device will ensure the maneuverability of the vehicle in the non-ventilated area and localize the emission of exhaust gases within the sealed walls of the gas receiver, the device is reliable and easy to manufacture.
