Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application] The present invention relates to a tank for containing a liquid (eg, water), that is, a liquid tank (eg, a water tank).

[Conventional technology]

As a liquid tank, for example, there is a water tank for a running water pool. In the case of a running water pool, a water tank 51 is installed on a base 52, as shown by the alternate long and short dash line in FIG. The aquarium body 51 is divided into a central portion of the aquarium body consisting of three divided pieces 51b and both end portions consisting of divided pieces 51a, 51a sandwiching the divided piece 51b, which is a joint side of the divided pieces 51a ..., 51b. As shown in FIG. 5, there are flange portions 61 protruding outward,
61 is formed, and the divided pieces 51a and 51b are joined by the flange portions 61 and 61 to form one tank. The flange portions 61 are connected to each other with bolts 62 and nuts 63.

As described above, when the water tank body is composed of a large number of divided pieces, it is advantageous in terms of manufacturing, transportation, etc., as compared with the case where the water tank body is not divided.

[Problems to be solved by the device]

However, in the case of the water tank 51, there is a drawback that the base 52 is difficult to process, and that the construction and maintenance of the drainage system are also difficult.

The reason why the base 52 is difficult to process is that the escape grooves 55 and 56 of the flange portions 61 and 61 projecting to the bottom of the water tank 51 need to be formed in the base 52 in advance. Escape groove 55 provided on the base 52,
As shown in FIGS. 6 (a) and 6 (b), 56 is considerably long and difficult to machine.

The construction and maintenance of the drainage system is difficult because the drainage hole 51c of the water tank 51 is located substantially in the center of the divided piece 51a at the end, as shown in FIG. 6 (a). The reason why the drainage hole 51c is opened at this position is to make the pipe length the same regardless of whether the drainage pipe is pulled out to the left or right, but in this case, the escape groove 57 of the drainage pipe formed in the base 52 is , Fig. 6 (a)
As can be seen from (c), it is quite long and difficult to process.
In addition, if the drain hole 51c is separated from the side surface of the water tank, piping work becomes difficult, and it is not easy to check water leakage at the connection point between the drain hole 51c and the drain pipe after construction. Thus, construction and maintenance of the drainage system is difficult.

In view of the above circumstances, it is an object of the present invention to provide a practical liquid tank which facilitates the processing of the base for mounting the liquid tank and facilitates the construction and maintenance of the drainage system.

[Means for solving the problem]

In order to solve the above problems, the liquid tank according to the present invention,
The liquid tank body is divided into a central portion composed of at least one divided piece and both end portions sandwiching the divided piece, and a flange portion projecting outward is formed at a joint side of each divided piece. In a configuration in which the divided pieces are joined together at the flange portions to form one tank, a leg portion protruding higher than the flange portion is formed at the bottom portion of the divided pieces at appropriate positions,
A drainage hole is formed near the side wall of the divided piece located in the central portion of the liquid tank.

 Hereinafter, the liquid tank of this invention will be described more specifically.

The liquid tank main body is divided into three parts, a central part and both end parts, but the central part and the end parts need not be one piece.
As a specific example of division, as shown in FIG. 2, there are three divided pieces 1b, 1b, 1b at the central portion and divided pieces 1a, 1a at both end portions. In FIG.
Another example of the division is that the division piece 1b is further divided into upper and lower parts at a position indicated by a chain line C.

The divided pieces 1a and 1b are coupled to each other by fastening the flange portion 12 formed on the seam side with, for example, a bolt or a nut.

The legs of the liquid tank may be provided, for example, at the bottom of all the divided pieces 1a and 1b, or, for example, the leg is not provided only for the divided piece 1b that comes in the center among the three divided pieces 1b. Part formation may be performed only on the selected specific divided pieces.

In the liquid tank of this invention, a drainage hole is provided near the side wall 19 of the divided piece 1b.
20 are formed. In the case of FIG. 2, since the divided piece 1b having the drainage hole 20 has a shape that can be joined even when inverted right and left (upside down in the figure), the drainage pipe can be taken out either left or right. In addition to being able to reverse right and left, it also has three split pieces
If there is compatibility between 1b, the drainage pipe extraction position will be more selective.

The liquid tank 1 of this invention is installed on the bases 2 and 2'as shown in FIG. 3 (a) or FIG. 4 (a). The material for forming the base is not particularly limited. For example, various bases such as an inorganic base using cement, a metal base, an inorganic / metal combined base can be used.

The liquid tank of this invention is used, for example, as a water tank of a running water pool, but is not limited to this. For example, it may be used for a fish tank or a liquid tank for storing chemical liquid.

[Action]

In the case of the liquid tank according to the present invention, it is easy to process the base on which the liquid tank is placed.

This is because the leg portion protrudes higher than the flange portion, and it is not necessary to provide the escape groove of the flange portion on the base.

Further, in the case of the liquid tank according to the present invention, construction and maintenance of the drainage system are easy.

Easier to process the base for piping work. When the gap between the bottom of the liquid tank and the legs on the surface of the base can be passed, the escape groove of the drainage pipe is unnecessary, so the base 2 has a flat surface as shown in FIGS. 3 (a) and 3 (b). Depending on the diameter of the drainage pipe, a groove may be provided, but since the drainage hole is near the side wall, it is formed on the base 2'as shown in FIGS. 4 (a) and 4 (b). This is because the groove 21 to be formed is extremely short.

It is easy to check water leakage after piping work and construction. There is a leg gap between the bottom of the liquid tank and the surface of the base, and the drainage hole is near the side wall, which makes the work extremely easy.

〔Example〕

An embodiment of the liquid tank of the present invention will be described below in detail with reference to the drawings.

FIG. 1 shows the installation state of the running water pool water tank of the embodiment from the side.

The aquarium body of the aquarium 1 is divided into three divided pieces 1b, 1b and 1b at the central portion and divided pieces 1a and 1a at both ends, respectively, as shown in FIG. Each divided piece 1
A flange portion 12 that protrudes outward is formed on a side that is a seam of a and 1b.

As shown in FIG. 1, leg portions 13 projecting higher than the flange portion 12 are formed at the bottom of the divided pieces. That is, the top portion 13a of the leg portion 13 is the top portion 12a of the flange portion 12.
It is ahead of the distance l. Therefore, there is no need to form an escape groove for the flange portion 12 on the base 2.

On the other hand, a drainage hole 20 is formed near the side wall 19 of the divided piece 1b. Therefore, the construction and maintenance of the drainage system is easy as described above. To change the direction of drainage removal, reverse the direction of the split piece 1b with drainage hole 20.

As shown in FIG. 1, each of the divided pieces 1a and 1b has a packing 17
The flange portions 12 and 12 are coupled with each other by fastening them with a bolt 15 and a nut 16.

At the stage when the construction is completed, the water tank 1 is assembled on the base 2 as shown by the one-dot chain line in FIG.

[Effect of device]

As described above, the liquid tank according to the present invention is very practical because it is easy to process the base for mounting the liquid tank and the drainage system can be easily constructed and maintained.
