Abstract
The utility model relates to a rainproof cap capable of realizing automatic opening and closing, which is mounted at the tail end of an exhaust pipe of a diesel engine. The rainproof cap mainly solves problems that a smoke outlet of a diesel engine is mounted perpendicularly upwardly, rain, snow and other foreign matters are easy to fall into a smoke outlet pipe to block an exhaust pipe when the diesel engine stops running, some diesel engines are provided with umbrella-shaped rainproof caps, but a space which is sufficient for exhausting waste gas is necessarily reserved between each umbrella-shaped rainproof cap and a smoke outlet while the umbrella-shaped rainproof caps cannot solve the problem of foreign matters entering smoke outlet pipes. The rainproof cap capable of realizing automatic opening and closing is characterized in that a circular cover plate is connected onto a coupling via a counterweight shaft. The rainproof cap is simple in structure, and is convenient in installation due to the fact that the coupler only needs to be fixed to the tail end of a smoke outlet pipe during usage, opening and closing of the rainproof cap are synchronous with starting and stopping of the diesel engine, the circular cover plate is opened when the diesel engine starts, and covers a smoke outlet of the diesel engine when the diesel engine stops, labor or other auxiliary equipment is omitted, and foreign matters are prevented from falling into the smoke outlet pipe of the diesel engine.
Description
Technical field
The utility model relates to a kind of rainhat, but relates to the rainhat of automatic on-off on the Diesel Engine Exhaust Pipe tail end specifically.
Background technique
The smoke exhaust port of diesel engine exhaust system level is sometimes installed, and installs vertically upward sometimes.A kind of mounting type after taking, if during the diesel engine operation, the high temperature that smoke exhaust port is upwards discharged has the waste gas of certain pressure, at this moment, sleet and other foreign matters just can not fall into smoke-ejecting pipe, but when the diesel engine operation stops, if smoke exhaust port does not have shield, sleet and other foreign matters will be easy to fall into smoke-ejecting pipe, might not cause outlet pipe ponding or blocked if often do not clear up.Common way be exactly with the rainhat of umbrella shape retaining above smoke exhaust port, do like this and can play certain screening effect, but during the diesel engine operation is to want combustion gas, therefore must reserve enough spaces between smoke exhaust port and the umbrella shape rainhat is beneficial to waste gas and discharges, so, just sleet can not be stopped fully and other foreign matters enter smoke-ejecting pipe.
Summary of the invention
The purpose of this utility model is at above-mentioned deficiency, and a kind ofly smoke-ejecting pipe thoroughly being sealed can be implemented in diesel engine and shut down the time of proposing, but and when moving, can open automatically by diesel engine so that the rainhat of the straightway automatic on-off of smoke-ejecting pipe.
Technical solution of the present utility model is, but the rainhat of automatic on-off is: circular cover is connected on the anchor ear by the equilibrate counterweight axle.
Equilibrate counterweight described in the technical solution of the present utility model is vertically fixed on the circular cover.
Be fixed with a support on the outer annulus edge of the anchor ear described in the technical solution of the present utility model, equilibrate counterweight is connected on the support by running shaft.
The utility model is fixed on the anchor ear on the rainhat smoke-ejecting pipe end and circular cover is just covered smoke exhaust port fully.When diesel engine moved, the waste gas of band pressure backed down circular cover opened smoke-discharging pipeline and combustion gas; When diesel engine was out of service, no waste gas acted on the circular cover, and circular cover freely falls seals the smoke evacuation pipeline.The utility model is because have only 5 findings that are very easy to make to form, so structure is simple especially; Only need during use anchor ear is fixed on the smoke-ejecting pipe end, therefore easy for installation; The opening and closing of rainhat and the start and stop of diesel engine are carried out synchronously, and automatically operation, response do not need artificial or other supplementary equipment rapidly, so very economical and practical.
Description of drawings
Fig. 1 is the structural representation of the utility model opening state.
Fig. 2 is the structural representation of the utility model closed condition.
Embodiment
As shown in Figure 1, 2, the utility model comprises circular cover 2, equilibrate counterweight 5, running shaft 3, support 4 and anchor ear 1.Circular cover 2 is connected on the anchor ear 1 by 5 of equilibrate counterweights, circular cover 2 is complementary with anchor ear 1 size, equilibrate counterweight 5 be one plate-like, be vertically welded on the circular cover 2, axial welding one support 1 at the outer annulus edge upper edge of anchor ear 1 anchor ear 1, an axis hole is respectively arranged on equilibrate counterweight 5 and the support 4, and running shaft 3 passes axis hole equilibrate counterweight 5 and support 1 is connected into an integral body.During use anchor ear 1 is fixed on the end of smoke-ejecting pipe, and circular cover 2 is just covered smoke exhaust port fully, when diesel engine moves, the waste gas of band pressure acts on the circular cover 2, and overcomes the gravity of circular cover 2 and equilibrate counterweight 5, and they are turned clockwise around running shaft 3, opened smoke-discharging pipeline combustion gas, when circular cover 2 be opened to about 60 the degree about, equilibrate counterweight 5 contacts with the smoke-ejecting pipe outer wall, forms spacing automatically; When diesel engine was out of service, no exhaust gas pressure acted on the circular cover 2, and circular cover 2 freely falls under the effect of gravity again with equilibrate counterweight 5 smoke-ejecting pipe is thoroughly sealed.
Claims (3)
1. but the rainhat of an automatic on-off is characterized in that: circular cover (2) is connected on the anchor ear (1) by equilibrate counterweight (5) axle.
2. but the rainhat of automatic on-off according to claim 1, it is characterized in that: described equilibrate counterweight (5) is vertically fixed on the circular cover (2).
3. but the rainhat of automatic on-off according to claim 1, it is characterized in that: be fixed with a support (4) on the outer annulus edge of described anchor ear (1), equilibrate counterweight (5) is connected on the support (4) by running shaft (3).
