DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a wind ventilator according to the present invention will be described with reference to the drawings. First, a wind ventilation device according to a first embodiment of the present invention will be described. FIG.
It is a front view of the wind ventilation device of the first embodiment of the present invention. A wind ventilator 1a according to an embodiment of the present invention is provided with a vent 2 rotatably provided in a ventilation pipe 4 communicating with a place requiring ventilation as shown in FIG. The vanes 3 of the weathercock are mounted on the ventilation pipe 4 so as to remove rainwater if necessary. The ventilation port 2 is connected to the ventilation pipe 4 in the direction of the vanes 3 of the weathercock, that is, in the direction in which the wind comes. It is mounted so that it can be rotated using the joint 5. The tip of the vent 2 may be vertically cut or obliquely cut so as to be longer as shown in FIG. This vent 2
Is determined according to the blowing distance and the blowing volume.

The joint 5 may be any one as long as the vent 2 can be connected to the ventilation pipe 4 so as to be rotatable. As shown in FIG. 1, a flange 2a fixed to the vent 2 is used. It is preferable that the ball 6 be inserted between the ventilation pipe 4 and the flange 4a fixed to the ventilation pipe 4 because the rotation of the ventilation port 2 is facilitated. Further, the vanes 3 of the weathercock of the wind ventilator 1a may have any shape as long as the vent 2 can be directed in the direction in which the wind comes. Also, the mounting position may be on the air vent 2, on the rear side, or at any other position. However, the air vent 2 and the blades 3 may be attached at a position where the center of gravity coincides with the rotation axis of the air vent 2. Is preferred. Also, this wind ventilation device 1a
As shown in FIG. 4, a rain water removing device 19 is mounted on the ventilation hole 2 or the ventilation pipe 4 to fix a frusto-conical rain water receiver 20 and a punching plate or the like on the rain water receiver 20 as shown in FIG. The filter 21 may have a structure in which a drain hole 22 is provided beside the rainwater receiver 20, or may have a structure of another well-known rain pattern.

In one embodiment of this wind ventilator 1a, a rotatable vent 2 is provided, and a weathercock wing 3 is attached to the vent 2, as shown in FIG.
The ventilation pipe 4 fixed to the concrete wall 30 or the like is used. Since the wind ventilation device 1a can directly send wind to a place where ventilation is required, it is effective for ventilating the underground pit 29 and the like. Also,
The wind ventilator 1a can be used as a ventilator or an auxiliary ventilator in a pit in the ground, a sewer space or a tunnel where there is no problem even if a little rainwater enters.

Next, a wind ventilation device according to a second embodiment of the present invention will be described. FIG. 2 is a front view of a wind ventilation device according to a second embodiment of the present invention. The wind ventilator 1b is the same as the wind ventilator 1a according to the first embodiment of the present invention, as shown in FIG. The vent 2 of the wind ventilator 1b may be the same as that of the wind ventilator 1a of the first embodiment, or the tip of the vent 2 may be widened to have a trumpet shape. Further, the ventilation pipe 4 and the joint 5 may be the same as those of the wind ventilation device 1a of the first embodiment. The vanes 3 of the weathercock may be the same as those of the wind ventilator 1a of the first embodiment, but the center of gravity of the wind vent 1a is larger than that of the wind ventilator 1a of the first embodiment. Since it is difficult to match the axis, it is preferable to make the tip of the blade 3 heavy or attach a heavy one.

The wind ventilator 1b can be used in the same way as the wind ventilator 1a of the first embodiment, but ventilates by sucking air (by entering from the surroundings). It is suitable for ventilation of houses, factories, warehouses, etc. because it does not allow rainwater to enter.

Next, a description will be given of a wind ventilation device according to a third embodiment of the present invention. FIG. 5 is a front view, partially broken away, of a wind ventilator showing a third embodiment of the present invention, FIG. 6 is a plan view of an example of a ventilation control device shown in FIG. 5, and FIG. FIG. 7 is a plan view of a state in which a lid on another airflow amount adjusting device is removed. This wind ventilator 1c
Is a device similar to the wind ventilation device 1a according to the first embodiment of the present invention, except that a ventilation control device is attached to the wind ventilation device 1a, so that the ventilation does not increase even when the wind becomes strong. The vent 2 of the wind ventilation device 1c may be the same as that of the wind ventilation device 1a of the first embodiment,
As shown in FIG. 5, the shape cut obliquely in the vertical direction is slightly smaller than the shape
This is preferable because the amount of air flowing in from the air greatly decreases. The vanes 3, vanes 4, and joints 5 of the weathercock may be the same as those of the wind ventilator 1a of the first embodiment.

[0011] The air flow control device of the wind ventilation device 1c is as follows.
The ventilation amount adjusting device 7a as shown in FIG.
The air flow control device 7b as shown in FIG. The air flow control device 7a fixes the wind force adjusting plate support member 10 to a mounting member 8 such as a mounting ring fixed to the ventilation port 2, and adjusts the wind force to the tip of the wind force adjusting plate support member 10 via a rotating pin 13. Attach the plate 9a, and furthermore, place a coil spring between the wind control plate support member 10 and the wind control plate 9a.
11 and the stopper 12 are attached. When the wind comes from the front, the wind adjusting plate 9a is opened by the wind, so that the wind adjusting plate supporting member 10, the attaching member 8 and the vent 2 are rotated. It was done.

The ventilation amount adjusting device 7b fixes a housing 14 having a lid on the upper and lower sides to a mounting member 8 such as a mounting ring to be fixed to the ventilation port 2, and has a coil spring mounting screw groove 18 in the housing 14. The wind adjustment plate guide plate 16 provided with the wind adjustment plate is fixed so as to be oblique to the mounting member 8, and the wind adjustment plate guide plate 17 is fixed so as to sandwich the wind adjustment plate 9 b having a curved tip. Insert the coil spring mounting screw through the groove 18 for the coil spring mounting screw through the plate 9b.
15 is screwed and fixed, and the coil spring 11 is mounted between the coil spring mounting screw 15 and the housing 14. In the ventilation amount adjusting device 7b, when wind comes from the front, the wind force adjusting plate 9b is pulled out by the wind, and the housing 14, the mounting member 8 and the ventilation hole 2 are rotated by the wind force.

As shown in FIG. 5, one embodiment of the wind ventilator 1c is a vent 2 which is rotatable around a ventilation pipe 4 fixed to a roof 23 and whose end is cut obliquely in the vertical direction. The weathercock 2 is provided with the vanes 3 of the weathercock and the ventilation amount adjusting device 7a, and the rainwater removing device 19 is further provided. When the wind is weaker than a certain level, the wind ventilator 1c does not rotate because the wind regulation plate 9a does not open, and the vent 2 does not rotate. Therefore, the wind enters from the entire area of the diameter of the vent 2, but the wind is strong. The wind regulation plate 9a opens
(Before) The wind causes a force to rotate counterclockwise due to the wind, and rotates the vent 2 until the force and the force to rotate clockwise of the blade 3 are balanced. Since the end of the vent 2 is cut obliquely in the vertical direction, as a result, the area through which the wind enters from the vent 2 is reduced, and the amount of ventilation does not increase. When the wind becomes stronger, the wind adjusting plate 9a is further opened to rotate the vent 2 further, and as a result, the ventilation does not increase. The ventilation amount of the wind ventilation device 1c in the case of strong wind can be determined by the strength of the coil spring 11 and the cutting angle of the tip of the ventilation hole 2.

In the above-described embodiments and examples, the wind-ventilating device 1a according to the first embodiment is shown as being provided with the air-flow adjusting device. Of course, it can also be attached to the wind ventilation device 1b.

[0015]

The wind ventilator of the present invention can be manufactured inexpensively by adopting the above-mentioned structure, and can provide ventilation without running cost and with almost no maintenance. It has an excellent effect that it can be performed.
