Description

[Detailed description of the invention]

[0001]

[Industrial application] The present invention relates to ventilation of water storage tanks and the like.
Regarding the structure .

[0002]

2. Description of the Related Art Ventilation of conventionally used water storage tanks
The structure will be described with reference to FIG.
2a is an integrally molded product made of synthetic resin such as FRP.
A plurality of unit panels 2 are connected to each other,
Fasten with bolts and nuts 2b through the kin, roof
3, a tank 1a having a side wall 4 and a bottom wall 6 is formed.
A ventilation pipe 8 is attached to the roof 3 of the tank 1a to perform ventilation.
I am .

[0003] The tank 1a is provided on the side wall of the tank 1a.
When the level of water stored inside rises abnormally, the tank
An overflow pipe 7 is provided to prevent breakage of 1a. The overflow
The water pipe 7 has one end facing above the inside of the tank 1a and the other end.
Is fixed to the side wall 4 so as to face the outside of the tank 1a.
When the water level inside the tank 1a rises,
Allows the stored water to flow in from the end 7a and flows out from the end 7b.
I'm making it. If the water level is not abnormally high,
7 serves as a simple vent pipe, so that the single part 7b
Is equipped with a meshed lid 7c to prevent ingress of garbage and small animals.
Have been placed .

[0004]

[Problem to be solved by the invention] However, FIG.
The conventional ventilation method shown has the following problems,
It was not preferred. That is, the first is the ventilation pipe 8
And a part of the overflow pipe 7 is installed outside the tank 1a.
To prevent clogging of the net or filter
The second is that snow is on the tank 1a in winter.
If it is piled up, the ventilation pipe 8 will not fulfill its function.
And thirdly, if you keep using the tank 1a for a long time,
The lid 7c comes off and garbage and small animals enter.
You .

The present invention has been made in view of the above problems.
Therefore, even if the tank is installed outdoors,
No clogging of filters etc.
To provide a tank venting structure without
You .

[0006]

Means for Solving the Problems To solve the above problems,
For this purpose, as shown in FIG.
A plurality of unit panels 2 having
Box formed by tightening bolts and nuts 2b
In the ventilation structure of the tank 1, one end is inside the tank 1.
Facing the upper part, and the other end is below the outside of the tank 1.
The overflow pipe 7 facing the side wall 4 or the bottom wall 6 of the tank 1
On the other hand, it was fixed through
At the end, an opening 13a is provided on the upper surface, and a filter is provided inside.
11 or a net and a float 1 provided with through holes in the vertical direction
2 is arranged vertically with respect to the overflow pipe 7.
Movably in the direction below the lower peripheral wall of the cylindrical body 10a.
Characterized in that at least one lower opening 14 is provided in the
And

The cylindrical body 10a used in the present invention has an additional
An opening 13a shown in FIG. 1C is provided on the surface,
Air enters and exits through the opening 13a.
You. The filter 11 and the float 12 are
The float 12 is provided above the inner wall of the body 10a.
The air that flows in and out of the opening 13a
Hole 12a is provided as a through hole for this .

The lower opening 14 referred to in the present invention is the same as that shown in FIG.
As shown in (b), below the cylindrical body 10a
Notches or holes are provided on one side. Lower opening 1
4 indicates that when the water level in the tank 1 rises abnormally,
It is used to drain stored water from the opening.
4 places at 90 degrees to each other to get more mouth area
Preferably, a notch is provided .

[0009]

FIG . 1A is a perspective view showing one embodiment of the present invention.
FIG. 4 is a cross-sectional view of the unit 1, and is a unit body provided with a joining edge 2 a around the periphery.
Packing two panels with bolts and nuts 2b
Box with a roof 3, side walls 4 and bottom wall 6
Forming the body. The overflow pipe 7 is tanned by the mounting seat 15.
To the upper side of the tank 1
However, the other end faces downward outside the tank 1 .

The end 7a of the overflow pipe 7 on the inner side of the tank 1.
Has a cylindrical body 10a shown in FIG.
The cylindrical body 10a is shown in FIG. 1 (c).
Opening 13a is provided on the upper surface, and
A filter 11 and a float 12 are arranged. Said
The air flowing into and out of the opening 13a is supplied to the float 12.
A hole 12a is provided for passage. Cylindrical body 10
1a, as shown in FIG. 1 (b), in addition to the opening 13a,
Also, a notch is provided at the part overlapping the overflow pipe 7 to open the lower part.
The mouth 14 is formed. The lower opening 14 is provided in the tank 1
When the stored water in the tank rises abnormally, the stored water is
It becomes an outlet for discharge .

The movement of the cylindrical body 10a will be described.
First, in the state shown in FIG. 1B, the water surface 16 is
10a, the cylindrical body 10a is under its own weight.
At the lowest height of the operating range, and the overflow pipe 7
Acting as a tube .

Next, the water level in the tank 1 rises abnormally.
When doing so, the water surface 16 is raised as shown in FIG. 2 (a), off
The inner lid 10 (tubular body 10a) is placed on the water surface by the funnel 12.
Rise together. At this time, the lower opening 14 also rises.
Therefore, the stored water flows into the overflow pipe 7 and falls below the water level in the tank 1.
I can. The filter 11 is, as shown in FIG.
The water level rises because it is located directly above the funnel 12.
The heart that does not get wet by polluting the stored water
There is no distribution .

[0013]

[Effect of the invention] According to the invention, a cylindrical shape having a filter
The body was attached to the end of the overflow pipe inside the tank.
If the filter is installed outdoors, the filter
It is not easily polluted because it is not
Clogging does not occur. The overflow pipe also plays the role of a ventilation pipe.
It is not necessary to install a ventilation pipe on the roof because it also serves as
It is economical, and the ventilation pipe is buried in snow
There is no inconvenience that the performance is reduced .
