[0003]

By the way, the following problems have been pointed out in such a conventional example. That is, when the power generation device 1 is installed outdoors in a snowfall area, in the conventional exhaust duct 5, the upper side is open to the outside A for soundproofing as described above, and therefore the rectifying plate 6 is used during snowfall. There is a problem of failure of the exhaust duct 5 due to snowfall, such as snow being accumulated on the top, and eventually the snow blocks the upper opening of the exhaust duct 5, making it impossible to exhaust air during power generation.

In view of the above situation, the present invention has been made to solve the problems of the above-mentioned conventional example, and can be displaced between a use posture protruding outside and a non-use posture stored inside. By, for example, being able to pivotally displace around a horizontal axis, firstly, failure to occur due to snowfall is prevented, such as being unable to exhaust air due to snowfall, and secondly, this is a simple configuration. It is an object of the present invention to propose an exhaust duct for a power generator, which can be easily realized by.

[0005]

The technical means of the present invention for achieving this object is as follows. First, claim 1
About: That is, the exhaust duct of this power generator is used in a power generator in which an engine and a generator are housed and a fan is attached in a box body having an intake port and an exhaust port on a wall surface. The exhaust duct is provided at the exhaust port and can be displaced between a use posture and a non-use posture. In the use posture, the exhaust duct projects outward from the exhaust port and the upper side is opened to the outside. The exhaust port is opened, and in the non-use posture, the exhaust port is stored inside and the exhaust port is closed.
Next, claim 2 is as follows. That is, in the exhaust duct of the power generator according to claim 1, the exhaust duct is rotatable and displaceable between the inside and the outside around a horizontal axis provided at a lower portion of the exhaust port, and the counterweight is It is attached via the horizontal axis. Then, during power generation, the exhaust air pressure takes the use attitude against the counterweight, and during non-power generation, the counterweight takes the non-use attitude.

[0006]

Since the present invention comprises such means, it operates as follows. The exhaust duct of this power generator is in the use position during power generation, and is projected to the outside, the upper side is open to the outside, and the exhaust port is opened. Stored in and close the exhaust port. Further, in claim 2, such a use posture and a non-use posture are realized by the rotational displacement about the horizontal axis and automatically. That is, this exhaust duct is in the use posture against the counterweight by the exhaust pressure during power generation, and is in the non-use posture by the counterweight during non-power generation.

Therefore, firstly, since the exhaust duct has a stored non-use posture when not generating power, it is not affected by snow even when installed outdoors, and also has a use posture protruding outside during power generation. If the snowfall occurs, the snowfall will be melted and treated by the heat of the exhaust air. Therefore, the upper opening of the exhaust duct is not blocked by the snow, and the failure of the exhaust is prevented, so that the failure caused by the snow is prevented. Secondly, this is easily realized by a simple structure in which the exhaust duct can be displaced between the use posture and the non-use posture. Particularly, in the second aspect, it is realized very easily and easily by the rotational displacement about the horizontal axis and the automation using the exhaust air pressure and the counter weight.

The figure is a side view of a main part in a non-use posture.

First, the power generator 1 in general will be described with reference to FIG. 2 described above. In this power generator 1, an engine X and a generator Y are housed and a fan Z is attached in a box body 4 having an intake port 2 and an exhaust port 3 on a wall surface. That is, in the stationary power generation device 1 such as a private power generation device and an emergency power generation device, a box body 4 serving as a large box-shaped cover having an opened lower surface is used, and the front and side surfaces of the box body 4 are used. An intake port 2 and an exhaust port 3 are formed in the upper part of the wall surface of the above. Then, in such a box body 4 the engine X
And a generator Y are housed therein, the engine X is a diesel-type prime mover, and the generator Y utilizes the rotation of the engine X to generate electricity. Further, the engine X and the generator Y are installed on the floor and covered with a box body 4 from above, and in the box body 4, an air flow path indicated by an imaginary line in the drawing is shown. In order to form Q, a fan Z is attached and a partition wall is provided. In FIG. 2, M is a service door and N is an exhaust part of the engine X.

The exhaust duct 7 is provided at the exhaust port 3 of such a power generator 1. 1 will be mainly described, the exhaust duct 7 can be displaced between a use posture C shown in FIG. 1 (1) and a non-use posture D shown in FIG. 1 (2). Is. Then, in the use posture C, the upper side 8 is projected to the outside from the exhaust port 3 so that the upper side 8 is opened to the outside A and the exhaust port 3 is opened. In the non-use posture D, the upper side 8 is stored in the inside B from the exhaust port 3 and the exhaust port is opened. Close 3

The exhaust duct 7 will be described in more detail. First, the exhaust duct 7 is provided with a front surface 9 and substantially fan-shaped side surfaces 10, and an exhaust passage 11 is formed inside the exhaust duct 7.
The upper side 8 is opened as an opening, and the back surface 12 is also opened as an opening. The exhaust duct 7 is pivotally displaceable between the inside B and the outside A about a horizontal axis H provided at the lower portion of the exhaust port 3, and the counterweight 13 is interposed via the horizontal axis H. It is attached to the inside B side. That is, the horizontal axis H is attached between the base of the exhaust duct 7 and the lower portion of the exhaust port 3, and the front surface 9 of the exhaust duct has its horizontal axis H as a fulcrum, for example, approximately 60 degrees from vertical. It is possible to rotate and displace with a stance.

Further, in the exhaust duct 7, a counterweight 13 as a balancer is integrally fixed on the opposite side of the base of the exhaust duct 7 with respect to the horizontal axis H. The weight of the counterweight 13 allows the exhaust duct 7 to assume the use posture C by the exhaust pressure when the fan is driven to rotate and the exhaust path 11 exhausts the air. , Exhaust duct 7
Is set to such an extent that it can be rotationally displaced to the non-use posture D. Therefore, the exhaust duct 7 takes the use posture C against the counterweight 13 by the exhaust pressure during power generation, and the counterweight 13 during non-power generation.
Take a non-use posture D at. Reference numeral 14 in the drawing is a drain, and this drain 14 is provided near the base of the front surface 9 of the exhaust duct 7, and is provided to penetrate between the exhaust passage 11 and the outside A for draining water. .

The present invention is constructed as described above. Then it becomes as follows. The exhaust duct 7 of the power generator 1 is stored in the use posture C protruding to the outside A as shown in FIG. 1 (1) and the inside B as shown in FIG. 1 (2). It can be displaced to the non-use posture D.
The exhaust duct 7 is first set to the use posture C during power generation, protrudes from the exhaust port 3 to the outside A, and the upper side 8 opens to the outside A and the exhaust port 3 is opened. Then, by the fan Z of the power generation device 1, air is introduced from the intake port 2 into the box body 4
After cooling the engine X and the generator Y, which have been sucked into the inside B of the vehicle and have been driven to a high temperature, the exhaust duct 3 is exhausted from the exhaust port 3.
An air passage Q is formed which is exhausted from the open upper side 8 to the outside A through the exhaust passage 11 (see also FIG. 2). And like this, because the exhaust air goes upwards,
Noises from the engine X, the generator Y, the fan Z, etc. in the inside B of the box body 4 are also released to the upper side, and are difficult to be transmitted to the outside A on the ground side and below. The exhaust duct 7 is in the non-use posture D when not generating power, is stored in the inside B from the exhaust port 3, and closes the exhaust port 3 at its front surface 9.

Further, in the exhaust duct 7 of the illustrated example, such a use posture C during power generation and a non-use posture D during non-power generation are rotated about the horizontal axis H. It is realized by displacement and automatically. That is, this exhaust duct 7 is
Due to the exhaust air pressure passing through the exhaust air passage 11 for exhaust, the front surface 9 thereof is pushed and automatically pivotally displaced, and it projects against the counterweight 13 from the exhaust port 3 to the outside A of the box body 4, The use posture C in which the exhaust port 3 is opened is set. On the other hand, at the time of non-power generation, the counterweight 13 is automatically rotated and displaced, and is stored in the inside B of the box body 4, and its front surface 9
At the non-use posture D, the exhaust port 3 is closed.

Then, the exhaust duct 7 of the power generator 1 has the following first and second configurations. First of all
In addition, even if the power generator 1 is installed outdoors in a snowfall area, the exhaust duct 7 is set to the non-use posture D stored in the inside B of the box 4 of the power generator 1 when there is no power generation at all times. So
It is not affected by snowfall that accompanies snowfall. Therefore, when the use posture C is projected to the outside A of the box body 4 at the time of power generation after the use after the fact, there is no problem due to snowfall and snow accumulation until then, and the snowfall in the use posture C is as follows.
It is melted by the exhaust air heat from the flow passage Q of the air that reaches the exhaust air passage 11 via the engine X and the generator Y that have reached a high temperature, and the drain 1
Since the data is processed from No. 4 to the outside A, no trouble is caused by this. As described above, according to the exhaust duct 7, unlike the conventional example of this kind described above, the opening of the upper side 8 of the exhaust duct 7 is not blocked by the snow during the snowfall. Failure due to snowfall is prevented, such as the inability to exhaust air is avoided.

Secondly, in the exhaust duct 7, the use posture C projected to the outside A of the box body 4 is to prevent the above-described first inability to exhaust air and prevent the occurrence of a failure. And the non-use posture D stored in the inside B are displaceable, that is, easily realized by a simple mechanical structure. Particularly, in the exhaust duct 7 of the illustrated example, these are easily realized with an extremely simple configuration by the rotational displacement about the horizontal axis H and the automation using the exhaust pressure and the counterweight 13. It

First, although the exhaust duct 7 of the illustrated embodiment is provided with the counter weight 13, the present invention is not limited to this, and for example, the counter weight 13 is not provided and the counter weight 13 is automatically provided. Alternatively, the exhaust duct 7 may be manually rotatable about the horizontal axis H between the use posture C and the non-use posture D. Secondly, although the exhaust duct 7 of the illustrated embodiment is rotatable about the horizontal axis H, the present invention is not limited to this. For example, the exhaust duct 7 may be manually operated. It is also possible to be able to displace between the use posture C and the non-use posture D by making it possible to slide in and out in the lateral direction.

[0018]

The exhaust duct of the power generator according to the present invention is
As described above, the following effects are exerted by being able to displace between the use posture protruding to the outside and the non-use posture stored inside, for example, being rotatable about the horizontal axis.

First, it is possible to avoid the inability to exhaust air due to snow. That is, as in the case of the conventional example of this kind described above, it is surely avoided that the upper opening is blocked by snow and the wind cannot be exhausted during power generation. Are prevented from being damaged by snow.

Second, and yet this is easily accomplished with a simple construction. That is, in the exhaust duct of this power generator, the above-mentioned first point is
It can be realized easily and almost maintenance-free, and it is also realized in terms of cost. In particular, the exhaust duct according to claim 2 is automated and can be realized very easily and easily with excellent cost. As described above, the effects of the present invention are remarkably large, such as the problems existing in this type of conventional example are eliminated.
