Description

  The present invention relates to a power generation device using, for example, an engine disposed in a housing as a prime mover, and more particularly to a structure of an exhaust duct.

In general, in large hospitals, shopping centers, and the like, it is known to install various power generation devices as a private power generation device, an emergency power supply device, or a combination of thermoelectrics.
For example, there is a conventional power generator as shown in FIG. 8, and FIG. 8 shows a case where the power generator main body 2 using a diesel, gasoline, or other engine as a prime mover is disposed in the housing 3. It is driven by the engine and generates electricity.

  Further, the exhaust gas generated when the engine constituting the power generation device main body 2 is driven is silenced by the exhaust silencer 5 and discharged from the exhaust duct 7 to the outside of the housing 3. Then, in order to cool the power generation device main body 2 and the like, as shown by the arrow A, the cooling air is caused to flow into the housing 3 and the cooling air after the power generation device main body 2 and the like are cooled is indicated by the arrow B as shown by the arrow B. It flows out of the Howzink 3.

  By the way, in the power generation apparatus as described above, the exhaust duct 7 for leading the exhaust gas silenced through the exhaust silencer 5 to the outside of the housing 3 is provided through the upper portion of the housing 3 as an example. The exhaust end 7a of the exhaust duct 7 is disposed in the lateral direction. Further, the exhaust port 8 provided at the exhaust end 7a of the exhaust duct 7 has a configuration in which the upper side of the exhaust port 8 protrudes laterally from the lower side, and rainwater is discharged from the exhaust port 8 in the rainy weather. Is prevented from entering the exhaust end 7a.

JP 2005-323473 A Japanese Patent No. 4153744

  In the conventional power generator described above, the exhaust end portion 7a of the exhaust duct 7 is disposed in the lateral direction. Therefore, for example, such a power generator is installed on the seaside or on the roof of a high-rise building. In such a case, a strong cross wind may blow into the exhaust end 7a of the exhaust duct 7 from the exhaust port 8. The same applies to typhoons.

  That is, as shown in FIG. 9, the exhaust gas flows in the lateral direction in the exhaust end portion 7a of the exhaust duct 7 as indicated by the arrow P, and the exhaust port 8 is discharged out of the housing 3. As indicated by Q, the air is blown into the exhaust end portion 7a of the exhaust duct 7 from the exhaust port 8, and the flow of the exhaust gas is obstructed.

  Therefore, the exhaust gas efficiency of the engine which comprises the electric power generating apparatus main body 2 will fall, and the subject which becomes a state unpreferable for the engine side occurred.

  By the way, as a measure against cross wind, generally, a method of arranging the exhaust outlet of the exhaust duct upward is taken. In such an arrangement method, a large amount of rainwater enters the exhaust duct directly from the exhaust outlet instead of being affected by the crosswind, and therefore, a drainage treatment of a large amount of rainwater is required.

  As this drainage method, for example, as shown in Japanese Patent No. 4153744, a drain hole 28 is provided on the bottom surface side of an exhaust pipe (exhaust duct) 26, and a drain pipe 32 is communicated with the drain hole 28 to be below. The rainwater that has entered the exhaust pipe (exhaust duct) 26 is drained from the drain hole 28 through the drain pipe 32, and this method is generally known.

  However, such a drainage structure can be easily applied to a new construction, but for example, measures against crosswinds are taken for existing equipment that has already been provided with an exhaust duct outlet sideways. In such a case, since it is necessary to change the exhaust duct to the exhaust port upward and to additionally install the drain hole 28 and drain pipe 32, the construction is relatively large, and the cost is also real. There was a problem that it was not right.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a power generator that can suppress the intrusion of a cross wind into an exhaust duct with a simple configuration.

Power generator according to the present invention includes a power generator body is disposed within the housing, the power generator and the exhaust muffler for muffling the exhaust gas generated within the body, said muted by flowing through the exhaust muffler exhaust An exhaust duct that exhausts gas to the outside of the housing and has an exhaust end located above the outside of the housing in a lateral direction, and an exhaust duct in which the upper side of the exhaust port of the exhaust end projects laterally from the lower side ; rectangular side mounting et al is on the lower side of the exhaust port of the exhaust end of the exhaust duct, a curved shape such that the other side is positioned above the upper side of the exhaust port of the exhaust end of the exhaust duct it is formed, in which crosswind provided a shield for shielding from entering the exhaust port of the exhaust end of the exhaust duct.
Also, power generating apparatus according to the present invention includes a power generator body is disposed within the housing, an exhaust muffler for muffling the exhaust gas generated by the power generator body, is silenced by flowing through the exhaust muffler An exhaust duct that exhausts the exhaust gas out of the housing and has an exhaust end located above the outside of the housing in the lateral direction, and an upper side of the exhaust port of the exhaust end projects laterally from the lower side; , while being spaced apart from said outlet port of the exhaust end of the exhaust duct, one side is positioned on the lower side of the exhaust port of the exhaust end of the exhaust duct, wherein the other side of the exhaust duct is formed in a curved shape so as to be positioned above the upper side of the exhaust port of the exhaust end, a shield crosswind to shield from entering the exhaust port of the exhaust end of the exhaust duct, The Is supported by the managing, it is provided with a support member for holding the shield.
