Description of the Related Art Conventionally, as a water storage tank of this type, one having a tank body configured by connecting a large number of large-diameter pipes having a diameter larger than that of a conduit for water passage is disclosed in Japanese Patent Laid-Open No. 55-116568. It is disclosed. With such a structure, the tank body is normally used as part of the pipeline, and in the event of an emergency such as an earthquake, the valves that are provided at both ends of the tank body and that connect to the pipeline can be closed. , This tank body will be used for water storage.

径が大きくなることから、槽内水の置換や拡散が必ずし
も十分ではないという問題点がある。However, in such a conventional one, although water is normally passed through the inside of the tank main body, the inside diameter of the tank is larger than that of the other parts of the pipeline, so that the inside of the tank is large. There is a problem that the replacement or diffusion of water is not always sufficient.
そこで本考案はこのような問題点を解決し、槽内水の置
換および拡散を良好に行えるようにすることを目的とす

になる。Action According to this structure, a part of the water flow in the tank main body passes through the narrow path between the partition plates, and the other part of the water flow is guided by the inclined partition plate so that the radial direction of the tank main body is increased. Flow outward, and then pass through a narrow path between the partition plate and the inner wall surface of the tank body. Then, by passing through these narrow passages, the flow velocity increases, and also by being guided by the partition plate itself and flowing along this partition plate, it is replaced early and diffused well in the tank body. It Further, since the pair of partition plates are arranged so as to incline toward the inner wall surface from the center of the tank body toward the downstream side, a narrow path is formed in the center of the tank body between the pair of partition plates. Even though a part of the water flow is allowed to pass, the other part of the water flow is reliably guided to the vicinity of the inner wall surface of the tank body, and the narrow portion between the partition plate and the inner wall surface of the tank body. Since the flow velocity increases after passing through the water, the replacement and diffusion of water near the inner wall surface where stagnation is likely to occur are reliably performed.

A tank body 2 formed of a cylindrical body having a diameter larger than the diameter of the pipeline 1 is provided in the middle of the pipeline 1. The tank body 2 has an inlet 3 and an outlet 4 for connecting to the conduit 1 at both ends in the length direction.

狭路部7,8が形成されている。A plurality of partition plates 5 are provided inside the tank body 2. Each partition plate 5 is configured by a rectangular plate that is vertically long in the vertical direction when the tank body 2 is installed horizontally as shown in the drawing, and each pair thereof is in the length direction of the tank body 2, that is, the water flow 6. Plural sets are provided with a distance in the direction. Further, each partition plate 5 is arranged so as to incline toward the downstream side from the central portion of the tank body 2 toward the inner wall surface. Further, narrow passages 7, 8 for passing the water flow 6 are formed between each pair of partition plates 5 and between the partition plates 5 and the inner wall surface of the tank body 2.

る。In such a configuration, a part of the water flow 6 that has entered the inside of the tank main body 2 from the conduit 1 through the inflow port 3 passes through the narrow passage portion 7, and the flow velocity is accelerated in the narrow passage portion 7. The other part of the water flow 6 is guided by the partition plate 5 and
Flow outward in the radial direction, and then pass through the narrow portion 8 to accelerate the flow velocity. And in this way the narrow part 7,8
The flow rate of the water flow 6 is increased by passing the water flow, and the partition plate 5 guides the water flow 6 outward in the radial direction to accelerate the replacement of the water in the tank main body 2 and It will be well diffused inside the tank body 2. In particular, the pair of partition plates 5 are attached to the tank body 2
Since it is arranged so as to incline toward the inner wall surface from the central portion of the tank, the narrow passage portion 7 is formed in the central portion of the tank body 2 between the pair of partition plates 5, and the water flow 6 is formed.
Despite the passage of a part of the water, the other part of the water flow 6 is surely guided to the vicinity of the inner wall surface of the tank main body 2, and the narrow space between the partition plate 5 and the inner wall surface of the tank main body 2. Since the flow velocity increases after passing through the passage portion 8, the replacement and diffusion of water near the inner wall surface where stagnation is likely to occur are reliably performed.
この結果、槽本体２の内部にはその中心部でも内壁面の
近傍でも淀みが発生せず、常に新しい水との入れ換えが

を経て下流側の管路１へ導かれる。As a result, stagnation does not occur inside the tank main body 2 either in the central portion or in the vicinity of the inner wall surface, and a state in which the water is constantly replaced with new water is maintained. And the water flow 6 is the outflow port 4
Through the pipe line 1 on the downstream side.
なお、流入口３および流出口４の位置は、槽本体２の設
置状況に合わせて適宜に変更することができる。The positions of the inflow port 3 and the outflow port 4 can be appropriately changed according to the installation situation of the tank body 2.

ることができるうえに良好に拡散させることができる。Effect of the Invention As described above, according to the present invention, since the partition plate that can form the narrow passage portion for increasing the flow velocity is provided inside the tank body, the water flow in the tank body is narrow. As the flow velocity increases in the section, it flows along the partition plate.In particular, the pair of partition plates are arranged so as to incline toward the downstream side from the center of the tank body toward the inner wall surface. Even though a narrow path is formed in the center of the tank body between the plates to allow a part of the water flow to pass, the other part of the water flow can be reliably guided to the vicinity of the inner wall surface of the tank body. In addition, since the flow velocity can be increased by passing through the narrow path between the partition plate and the inner wall surface of the tank body, it is possible to reliably replace or diffuse the water near the inner wall surface where stagnation easily occurs. Therefore, the water in the tank body should be In both the central part and the vicinity of the inner wall surface, the replacement can be performed early and the diffusion can be performed well.
