Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a device for preventing rainwater from entering a chimney.

[Conventional technology]

During rainy weather, rainwater enters the inside of the chimney from the top of the chimney,
In order to prevent this rainwater from entering, conventionally the top of the chimney was covered with a waterproof sheet or a lid made of wood or the like was attached.

[Problem that the invention seeks to solve]

However, all of the above methods involve working at heights, which is extremely dangerous for workers.
In addition, it required a great deal of time and effort, so it was rarely used in practice.

The present invention was made in order to solve the above-mentioned problems.In chimneys installed in incineration plants, etc., which are relatively often closed (exhaust gas does not pass through them), rainwater is removed when the furnace is closed. To provide a device for preventing rainwater from entering a chimney, which prevents water from entering the inside from the top of a chimney, and which can be operated relatively easily from a remote location such as the above-ground part (chimney base).

[Means for solving problems]

The present invention has been made to achieve the above object, and is a device for preventing rainwater from entering a chimney, in which a lid member that can be opened and closed is provided at the top of the chimney, and the opening and closing of the lid member is operated from a remote location. It provides:

[Effect]

The lid member is operated from a remote location to open and close the lid member, and when opened, gas is discharged from the chimney, and when closed, rainwater is prevented from entering the chimney.

〔Example〕

FIG. 1 and FIG. 2 are front views showing an embodiment of the rainwater intrusion prevention device according to the present invention in an open state and a closed state, respectively. 3 and 4 are views taken along arrows A and C in FIG. 2, respectively, and FIG. 5 is a view taken along arrow B in FIG. 6.

As shown in the figure, the rainwater intrusion prevention device 1 has an internal lug
This is a lid member provided at the top of a chimney 100 made of a covering material, and shaped so that it can be opened and closed freely at the top of the chimney 100. That is, the rainwater intrusion prevention device 1 is installed in the chimney 100
It consists of a lower rainwater intrusion prevention device 1a and a lower rainwater intrusion prevention device 1b that open and close on both sides.

For example, as shown in FIG. 6, the lower rainwater prevention device 1b has fan-shaped flat surfaces 2a and 2b on both sides of a curved surface 20, and an apex 2c of the fan-shaped flat surfaces 2a and 2b is provided at one end of the curved surface 2. , 2d, a rectangular parallelepiped-shaped riser 3 is provided toward the center of the chimney 100 in the opposite direction to the chimney 100. The upper rainwater intrusion prevention device 1a has the same shape as the lower rainwater intrusion prevention device 1b, but the radius of the fan-shaped plane is larger than the radius of the fan-shaped plane of the lower rainwater intrusion prevention device 1b. In the closed state, as shown in FIG. 5, they overlap in a vertically shifted manner. Reference numeral 4 denotes a rising portion provided on the lower rainwater intrusion prevention device 1a, which together with the rising portion 6 prevents rainwater from entering the inside of the chimney from the top of the chimney 100. In addition, upper and lower rainwater intrusion prevention devices 1a,
1bKi! As shown in FIG. 6, holes 4a and 4b are provided at the vertices 2c and 2an sides of the fan-shaped planes 2a and 2b. Upper and lower rainwater infiltration prevention devices 1a and 1b.

A rotating shaft 5 is passed through the holes 4a and 4b so that it can rotate at the top of the chimney 100. Further, a spring 7 is provided via a pin 6.6 on one side of the fan-shaped plane of the upper and lower rainwater intrusion prevention devices 1a and 1b. Also, upper and lower rainwater intrusion prevention devices 1a.

The corners of 1b @7a and 7bK are wire ropes 8a.

8b is provided. Further, members 9a and 9b are provided on both sides of the chimney 1000 to stop the upper and lower rainwater intrusion prevention devices 1a and 1b when they are opened. Note that the wire ropes sa and sb are guided to the base of the chimney 1000 via pulleys 10 and 11, and a winch 16 applies a pulling force. By the way, each member according to the present invention is made of a material that is resistant to corrosion against the exhaust gas from the chimney 100, such as 5US304.

A detailed explanation of the present invention configured as described above will be as follows. As long as the exhaust gas is passing through the chimney 100,
As shown in FIG. 1, the upper and lower rainwater intrusion prevention devices 1a and 1b of the rainwater intrusion prevention device 1 are arranged so that they do not get in the way when exhaust gas is discharged.

Chimney 1000 is placed open on both sides.

On the other hand, when the furnace is closed and the exhaust gas is not passing through, the upper and lower rainwater intrusion prevention devices 1a are installed as shown in Fig. 2.
, 1b are closed to cover the top of the chimney 100. First, in order to change the closed state shown in FIG. 2 to the open state shown in FIG. By winding the 13V wire rope 8a,
8b is pulled downward @, and the upper and lower rainwater infiltration prevention devices 1a, 1b are rotated in the downward direction O around the rotating shaft 5 to open the rainwater intrusion prevention device 1. The upper and lower rainwater intrusion prevention devices 1a and 1b rotate, and both ends are connected to pieces 9a and 9.
When it stops at point b, stop the winch 160 rotations and fix it.

Next, when passing the exhaust gas, rotate the winch 16 in the opposite direction to the arrow ■ shown in FIG.
When a and 8b are loosened, the force that causes the spring 7 to contract causes the upper part to
Lower rainwater intrusion prevention device 1a.

1b is rotated in the O direction shown in FIG. 1 and closed as shown in FIG. In this case, the radius of the upper rainwater infiltration prevention device 1a is smaller than the radius of the lower rainwater intrusion prevention device 1b. Therefore, as shown in FIG. It is closed with a slight shape at the top.Therefore, even if rain were to enter in the incoming direction in this state, the rise 6.4 would prevent rainwater from entering the inside of the chimney 100.

In the above explanation, the wire ropes 8a and 8b are both arranged downward, but the present invention is not limited to this, and by using a pulley or the like, the wire ropes 8a and 8b are arranged halfway down.
You can compile it into a book. In addition, in the above explanation, the wire ropes 8a and 8b are connected to the upper and lower rainwater infiltration prevention devices 1a.
Although the case where it is attached only to one side of 1b is shown, it may be attached to both side plates if necessary. Further, the shape of the spring 7, the capacity of the winch 13, the diameters of the wire ropes 8a and sb, etc. can be determined according to each condition.

〔Effect of the invention〕

As is clear from the above description, the present invention has the following remarkable effects.

(1) To prevent exhaust gas from passing through the chimney, it is possible to cover the top of the chimney very easily and securely by simply pulling or loosening the wire rope from the base of the chimney, preventing harmful rainwater from entering the lining material. Prevent it from entering the chimney.

(2) Since there is a gap between the top of the chimney and the rainwater intrusion prevention device, even if some warm air (or heat K) enters the chimney and creates an upward airflow, the discharge will not be hindered.

(3) Since the entire mechanism is relatively compact, it hardly spoils the appearance of the chimney.

(4) Since the operation can be performed at the base of the chimney, there is no need to work at heights, making it extremely safe.

(5) Unlike tarpaulin sheets, there is no risk of them being blown away by strong winds, and they are extremely durable.
