Description

  The present invention relates to a water storage tank for storing and filtering rainwater, and a bucket for the water storage tank.

  As is well known, the water storage tank is useful for rainwater that stores water for watering and water supply. Accordingly, various shapes and sizes of structures are commercially available from the viewpoint of cost and reuse, and drums are simply used. The present applicant also proposes a “rainwater filtration and storage device” described in JP-A-2006-28954. The present invention comprises a tank and a siphon pipe attached to the outside of the tank, and is provided with a faucet with a cock provided at the bottom for taking out the clarified water generated in the tank. The structure is simple and clear water can be generated. However, since the faucet is provided at the bottom, separation of dust and clarified water is not sufficient, and there is room for improvement.

  As a related document, there is "Rainwater storage tank" of JP-A-4-44534. The present invention is an assembling-type water storage tank that includes an inverted U-shaped siphon tube that is depressed in the water storage tank and is located outside the water storage tank, and a rainwater introduction path, and includes a filter inside. The present invention has a structure in which the siphon tube is depressed in the water storage tank, and the apex pipe portion of the siphon tube is under the top plate of the water storage tank, the capacity is reduced, and the siphon tube is disposed on the inner periphery of the water storage tank. It is considered that the dust collection effect cannot be expected because of the structure provided on the face wall.

  In addition, the literature which improved the bucket which is generalized with the instrument which clarifies the clear water of a water storage tank (water storage tank) is mentioned. For example, there is a “fire protection bucket” disclosed in Japanese Utility Model Laid-Open No. 50-39099. This device is a bucket provided with a pouring spout (water pouring spout), and the overall outer dimension (size) is a bucket size of a standard product. In this standard bucket, it is difficult to insert the lid on the upper surface of the water storage tank into the opened gap (opening portion) if the upper lid is opened (opened) only about half way. Therefore, a lower bucket is used, and there are improvements such as insufficient water volume and inability to respond quickly in an emergency.

  Hereinafter, the water storage tank 1 which concerns on this invention is demonstrated using FIGS. 1-5.

  Describing a preferred embodiment of the present invention, the water storage tank 1 is composed of a poly tank, an FRP tank, and a steel tank and is converged toward the bottom 100. The opening 1 a of the upper surface 101 has a fixed lid 2 that is large enough to cover the edge 102 of the opening 1 a, and an open / close lid 5 that is fixed to the fixed lid 2 via a hinge 3 and has substantially the same surface area as the fixed lid 2. It consists of and. The opening / closing lid 5 can be easily opened and closed as a folding type or a winding type, and the gap 6 (opening) formed by opening (folding or winding) the opening / closing lid 5 is enlarged. Etc. The gap 6 has a semicircular shape formed by the inner peripheral surface 1 b of the water storage tank 1 and the straight portion 2 a of the fixed lid 2.

  In the center 100a of the bottom 100 of the water storage tank 1, a discharge port 103 for discharging dust is opened. In addition, in the vicinity of the straight portion 2 a of the fixed lid 2, an inlet 104 for taking in rainwater (for introducing rainwater) is opened.

  A horizontal tube portion 10 a of the inverted U-shaped siphon tube 10 is connected to the outside of the bottom of the discharge port 103. Further, the horizontal pipe portion 10 a is arranged along the outside of the bottom portion, and the free end reaches the edge 102 of the water storage tank 1. As a result, the main body tube portion 10 b erected from the horizontal tube portion 10 a is erected outside the water storage tank 1. That is, in the same-type water storage tank 1, the maximum volume is secured in the interior 1-1, and the siphon tube 10 is configured not to be inserted in the interior 1-1 of the water storage tank 1. The purpose is to secure the volume for rainwater inflow as described above, and to secure an effective amount of water for emergency or watering. Further, the main body pipe portion 10b has an inverted U-shaped main shape, and the central apex pipe portion 10b1 is flush with the upper surface 101 of the water storage tank 1, so that rainwater can be filled into the entire upper surface 101 of the water storage tank 1. Can be captured. This is particularly effective when dust and / or rainwater is discharged to the outside through the siphon tube 10. An opening tube portion 10c is connected to the lower end of the main body tube portion 10b, and the dust or the like guided to the main body tube portion 10b is reliably drained. In the apex tube portion 10b1, one or a plurality of pores 11 for taking outside air are provided. A sub-tank 12 provided with a lid for dust and / or rainwater is arranged at the free end of the opening pipe portion 10c, and dust collection and / or rainwater is stored in the sub-tank 12. The sub tank 12 is provided with an air vent hole.

  The apex pipe part 10b1 is flush with the upper surface 101 of the water storage tank 1. The lower side 10b11 of the apex pipe part 10b1 is below the upper face 101, the upper side 10b12 of the apex pipe part 10b1 is the upper side of the upper face 101. There is. Therefore, when rainwater is introduced into the water storage tank 1 and the water level of the rainwater exceeds the lower side 10b11, the rainwater becomes water (exhalation water) below the siphon pipe 10 (rainwater is sequentially added). , The lower side 10b11 is exceeded), and at the same time, rainwater flows into the siphon tube 10 and discharges dust. Further, since the upper side 10b12 is on the upper surface 101, the rainwater does not exceed the upper surface 101, and the rainwater does not overflow the water storage tank 1. Further, in this embodiment, rainwater has a structure that flows approximately half of the apex pipe portion 10b1 (the positional relationship between the upper surface 101 and the apex pipe portion 10b1), and the introduction of outside air from the pores 11 is provided. The flow of rainwater in the siphon tube 10 is guaranteed. Further, the pores 11 can be used for introducing air into the apex pipe portion 10b1 and / or adjusting the water level of the water storage tank 1, and the like.

  In order to allow rainwater and / or dust to flow through the siphon tube 10, for example, it is desirable to use rainwater or the like as expiratory water. As described above, when the water level of the water storage tank 1 rises, it naturally occurs, and the concept is the same as in the conventional case.

  A rainwater introduction pipe 13 is connected to the inlet 104 of the water storage tank 1 provided in the fixed lid 2.

  In the figure, 20 is a bucket for holding a predetermined amount of clear water in the water storage tank 1 and is formed in a flat shape so that it can be inserted into the gap 6 of the opening / closing lid 5, and only one of the bowl-shaped spouts 20a is provided. It is provided on one side and the other (both sides) facing each other. As a simple method, a circular bucket (not shown) can be formed into a flat shape. Because of this shape, insertion into the gap 6 and drawing of water are possible. It can be used for watering far away and watering concentrated. In the figure, reference numeral 21 denotes a shank that can be inserted into the gap 6.

  Hereinafter, an example of the method of use of the present invention will be described. Rainwater is introduced from the introduction pipe 13 to the bottom 100 from the approximate center of the water storage tank 1, and the water surface rises sequentially and the inner peripheral surface 1 b of the water storage tank 1. As a result, the eddy current is generated. If necessary, a vortex generating means, for example, a nozzle (not shown) for carrying a flow in the tangential direction is attached, or the introduction pipe 13 is arranged in the tangential direction. The flow of the swirling flow of rainwater is used and finally reaches the upper surface 101. The swirl flow is used to be introduced at substantially the center of the upper surface 100 of the water storage tank 1. At the time of this introduction, a swirling flow is always generated, so that dust is collected at the center of the bottom 100. In particular, dust can be collected in combination with the converging shape of the outer shape of the water storage tank 1. Further, the flow of the swirling flow of rainwater is used, and finally reaches the upper surface 101. Utilizing this swirl flow, the separation of specific gravity is promoted and the internal volume of the water storage tank 1 is expanded (in comparison with a water storage tank “not shown” of the same form. The siphon tube 10 is externally attached. The sedimentation separation can be promoted by

  When the dust is collected and the rainwater reaches the water level on the upper surface 101 (when it exceeds the lower side 10b11 of the top tube portion 10b1 of the siphon tube 10), the rainwater becomes expiratory water, and the rainwater and dust are discharged from the outlet. 103 prevents the rainwater from being guided to the siphon tube 10 and overflowing from the upper surface 101. And the dust and rain water which reached this siphon pipe | tube 10 are discharged | emitted in the ground from the opening pipe part 10c, or are induced | guided | derived to the subtank 12. FIG.

  In addition, in order to scoop out (pump out) the clear water (supernatant water) on the upper surface 101, the opening / closing lid 5 is folded to create a gap 6, and pumped out using the bucket 20 inserted into the gap 6, or the shank 21. Use as watering. After this use, the opening / closing lid 5 is returned and closed.

  Moreover, it is desirable to apply coal tar to the inner peripheral surface 1b of the water storage tank 1 to eliminate the generation of algae and the growth of insects.

  The fixed lid 2 and the open / close lid 5 are provided with a collar portion (not shown) so as to completely cover the upper surface 101 and / or the edge 102, thereby protecting the water storage tank 1 from direct sunlight and the water storage tank 1 Avoid the rise of the temperature of rainwater and avoid the generation of algae.

  In the figure, reference numeral 22 denotes a base, in which the water storage tank 1 is disposed away from the ground to form a space, and a horizontal pipe portion 10a is disposed in this space.

  The above-described embodiment and the structure and effect described in the drawings show preferred examples of the present invention. Therefore, the invention having the same effects and features as those of the present invention is naturally within the scope of the present invention even in the other embodiments and the structures described in the drawings.
