【Example】

Embodiments of the present invention will be described below with reference to the drawings. In the first embodiment shown in FIGS. 1 to 3, 1 is a pipe for water flow, which is buried underground. A water storage tank 2 is interposed in the middle of this pipe line 1. There is. This water storage tank 2 has a plurality of large-diameter pipes 4 connected horizontally, and both ends of which are connected to closed-end pipes. It is composed of a tank body 3 which is closed at 5a and 5b. closed end tube 5a, A connection port 6 is provided at the upper part of each of the pipes 5b to connect the pipe 1 to the water storage tank 2. A tube 7 and an outflow tube 8 are inserted. The inflow pipe 7 hangs down to near the lower end of the closed end pipe 5a. and the plurality of inflow ports 7a are opened toward the outside in the axial direction of the tank body 3. Ru. Similarly, the outflow pipe 8 is also suspended near the lower end of the closed-end pipe 5b, and the plurality of flows are The outlet 8a is opened toward the outside in the axial direction of the tank body 3.

[0008] Inside the tank body 3, there are a plurality of holes arranged at appropriate intervals in the axial direction and perpendicular to the axial center. A flow control plate 10 is provided. As shown in FIGS. 2 and 3, these flow control plates 10 include On one side, there is a main water passage opening 11 with a large cross-sectional area formed by cutting out a part in an arch shape. A sub-water passage opening 12 consisting of a small hole is formed on the other side on the diametrically opposite side. So so that the main water passage openings 11 are alternately located up and down along the axial direction of the tank body 3. A flow control plate 10 is disposed in the tank body 3, and a meandering flow path is formed in the tank body 3. Also, The corners between the flow control plate 10 and the inner peripheral surface of the tank body 3 on both sides of the flow control plate 10 are They communicate with each other through a water passage opening 12.

[0009] According to the above configuration, water flowing into the water storage tank 2 from the pipe line 1 through the inflow pipe 7 is , flows out from the inlet 7a toward the end wall of the closed end pipe 5a, and stagnates at the end of the tank body 3. It flows into the inside of the tank body 3 without causing any turbulence. The inflowing water is controlled inside the tank body 3. A closed end on the outflow side along the meandering flow path formed by the main water passage opening 11 of the flow plate 10. It flows towards pipe 5b. Therefore, the diameter of the tank body 3 is larger than the diameter of the pipe line 1. Even if the flow rate is low, the flow velocity near the tank wall does not drop significantly and the flow continues without any stagnation. Furthermore, by providing the flow restricting plate 10, a Even relatively small stagnation areas can be eliminated by the water flowing through the secondary water passage opening 12. This ensures that all the water inside the tank body 3 is replaced. Closed end tube 5b The water that has reached the outlet 8a of the outflow pipe 8 faces outward in the axial direction of the tank body 3. Therefore, after flowing to the end wall side of the closed end pipe 5b, it flows into the outlet 8a, causing stagnation. Instead, it flows out into the pipe line 1 through the outflow pipe 8.

0010 In this way, stagnation does not occur inside the water tank 2, and water is constantly replaced with fresh water. Therefore, water quality can be ensured when used as the water storage tank 2. In the first embodiment, the flow control plate 10 is welded to an appropriate location on the inner peripheral surface of the large diameter pipe 4. Although an example in which the flow control plates 10 are fixed together has been shown, as in the second embodiment shown in FIG. The large-diameter pipes 4, 4, which are connected to the It may also be held.

[0011] Furthermore, in each of the above embodiments, the main water passage opening 11 is formed by an arch-shaped notch formed in the flow control plate 10. The secondary water passage openings 12 were formed with small holes, but their shapes could be arbitrarily selected. can do. For example, as in the third embodiment shown in FIGS. 5 to 7, from a large diameter hole A main water passage opening 21 may be provided.

0012 Furthermore, in each of the above embodiments, the tank body 3 was constructed by connecting a plurality of large-diameter pipes 4; A single tank body may be constructed using a contact structure or the like. Furthermore, in the above embodiment, the shaft center is Although the water tank 2 is illustrated as having a square tank body 3, the tank body 3 whose axis is vertical is It is also possible to form a water reservoir.

[0013]

[Effect of the idea]

As described above, according to the present invention, the main water passage openings are arranged alternately at both ends in the diametrical direction of the tank body. A meandering flow path is formed in the tank body by arranging multiple flow control plates so that the The water flowing into the tank body from the road is made to flow in a meandering manner within the tank body. Even if the diameter of the main body is larger than the diameter of the pipe, stagnation may occur in the flow of water within the tank body. In addition, there is a secondary water passage opening on the opposite side of the main water passage opening, so it is not necessary to use a flow control plate. By providing this, it is possible to eliminate relatively small stagnation areas that occur at the corners. For this reason, all the water in the tank body is constantly replaced, and the water quality when used as a water storage tank is can be ensured.
