Description

  The present invention relates to a rainwater utilization device that uses stored rainwater for watering a garden, washing a car, and the like.

In recent years, in order to effectively use water resources, rainwater is often used for car washing, watering on garden lawns, and the like. Conventionally, rainwater that has fallen on the roof or the top of buildings such as houses is collected in eaves gutters and discharged directly to the ground through several downspouts or installed separately. Discharge along drain pipes and drains. Therefore, a method of storing collected rainwater in a rainwater tank for effective use of the rainwater and supplying the collected rainwater to a necessary place at the time of use has been performed.
For example, Patent Literature 1 discloses a conventional technique using rainwater, in which a branch channel portion of a branch pipe branched from a vertical rain gutter and connected to a water receiving channel side is inclined downward toward the water receiving channel side to overflow. A rainwater utilization system (see FIG. 1) is described in which a merging section of a merging pipe connected so as to merge from a road to a vertical rain gutter is inclined downward from the overflow channel toward the vertical rain gutter.

Further, in Patent Document 2, rainwater falling in a vertical gutter is temporarily stored, a water level with a rainwater outlet is established, and the temporarily stored water is introduced into a water storage container at an arbitrary position. Rainwater is stored at a desired water level, and when the stored water exceeds the level, the water is overflowed from the temporarily stored water side and introduced into an underground drain to maintain the level (see FIG. 1). ) Is described. A water bucket is used as a water bucket.
Patent Literature 3 describes that a rainwater storage tank is integrally provided inside a building's sideboard (see FIG. 1). The tank is made of a material made of a synthetic resin such as vinyl chloride.

  As described above, a rainwater storage tank that effectively uses rainwater has been conventionally known, and has been useful for effective use of water resources. However, the conventional rainwater storage tank has the following problems. (1) Most of the material of the rainwater storage tank was formed of plastics such as vinyl chloride, and the presence of a material in consideration of light-shielding properties was not recognized. (2) Since the rainwater storage tank is installed directly on the ground, the bottom has a flat shape in many cases, and the mud tends to accumulate inside the storage tank. (3) When rainwater is stored in the rainwater storage tank for a long time, the quality of the stored rainwater is likely to deteriorate due to the influence of sunlight. (4) When rainwater is taken out from the rainwater storage tank, water is discharged by natural fall, so water is not discharged at a high water pressure, and the use of rainwater is limited. (5) It is difficult to check the amount of rainwater accumulated in the rainwater storage tank. (6) The temperature of rainwater in the storage tank is high in summer when the storage tank is exposed to sunlight, and water quality is likely to deteriorate. High temperature water has an adverse effect on plants and flowers, and low temperature in winter when exposed to cold. There is an adverse effect on the flowers, and at lower temperatures, freezing and the like are likely to occur. (7) The amount of storage in the storage tank is determined by the amount selected at the time of installation, and to increase the storage amount after installation, it was necessary to replace the storage tank with a large-capacity storage tank, which required cost and labor. (8) At the time of a peculiar natural phenomenon represented by a typhoon, there was no auxiliary fixture for preventing the storage tank from falling, and it was necessary to fix it with a rope when necessary.

  The present invention has been made under such circumstances, and has a structure in which a water-tight storage tank is used to maintain the quality of water, and is easy to remove mud inside the storage tank. Water can be discharged under high water pressure, and it is possible to wash the car and spray water over a wide area.The amount of rainwater inside the storage tank can be easily recognized from the outside, and the storage tank is not exposed to sunlight or cold wind. Provided is a rainwater utilization device that can easily enhance the fall prevention property.

The invention according to claim 1 includes a storage tank made of a light-shielding material for storing rainwater, a rainwater inflow pipe connected to a rainwater inlet of the storage tank, and the stored rainwater attached to the storage tank. An outlet for natural fall to be taken out, a pressurized pump housed inside the storage tank and pressurizing the stored rainwater, and an outlet for pressurized attached to the storage tank and taking out the pressurized rainwater to the outside A water level gauge comprising a base housed inside the storage tank and an indicator attached to the upper part of the storage tank, and heat insulation attached to one or more of the front, back, and both sides of the storage tank A protection panel made of a conductive material, wherein the storage tank has a U-shaped cross-section at the bottom and a drainage device at the bottom of the U-shape having a drain. As the light-shielding material, a rust-proof metal represented by stainless steel, a light-shielding plastic represented by colored polyethylene, a light-shielding FRP (fiber reinforced plastic) represented by colored FRP, or the like is used. Aluminum, duralumin, copper, copper alloy, etc., other than stainless steel, are used as the rust preventive metal. As the heat insulating material, wood represented by a wood panel, weather-resistant plastic, FRP, or the like is used.
The invention according to claim 2 is the invention according to claim 1, in which one or more of the front, back, and both sides of the storage tank is fixed with a coupling device and a fall prevention chain that communicate with another storage tank. It is characterized in that a hook is attached.

  In the invention according to claim 1, a light-shielding material is used for the storage tank, and as a result, the sunlight does not enter the storage tank, so that the deterioration of the rainwater quality in the storage tank is less than that of the conventional storage tank. It becomes possible to save. In addition, the lower part of the storage tank is formed in a U-shaped cross section to facilitate collecting dust and mud that has entered the inside of the storage tank, and cleaned water and mud from the drain provided at the bottom of the U-shaped cross section. Since the discharge can be performed, the inside of the storage tank can be easily cleaned. In addition, when a rust-preventive metal typified by stainless steel is used for the storage tank material, rust is unlikely to occur first, and it can be made thinner due to its material characteristics. The environment can be considered. Furthermore, since a pressurized pump is installed inside the storage tank, the water pressure of the rainwater flowing out of the outlet is high, and the car can be washed and a wide range of water can be sprinkled without having to refill the bucket or the jar, so that the initial fire extinguishing in the event of a fire can be prevented. Can also be used.

The conventional water pressure due to the natural falling pressure is about 0.01 MPa / cm ² or less, but when a pressure pump is used as in the present invention, the water pressure can be 0.02 MPa / cm ² or more. Further, the amount of stored rainwater can be checked from outside the tank by the water level gauge attached to the storage tank, so that the rainwater can be effectively used. A protection panel made of a heat insulating material is attached to one or more of the front, back, and both sides of the storage tank, for example, on the front side of the storage tank to prevent the storage tank from being directly exposed to sunlight or cold wind. In this way, the rise or fall of the rainwater temperature inside the storage tank can be reduced, and as a result, the influence of the rainwater temperature on the flowers can be reduced. Further, since the lowering of the rainwater temperature can be delayed more than before, the possibility of freezing of the rainwater decreases.
In the invention according to claim 2, since the connecting device is provided on one or more of the front surface, the back surface, and both side surfaces of the storage tank, the plurality of storage tanks are connected and communicated and treated as one storage tank. It is possible to make a large-capacity rainwater utilization device with a free arrangement. In addition, one storage tank can be set up at first, and it can be added when necessary, so that there is no need to replace the storage tank according to the capacity. In addition, the installation portion of the support leg is fixed by an anchor bolt or the like, so that the storage tank can be prevented from falling. Furthermore, hooks for fixing the fall prevention chain are attached to one or more of the front, back, and both sides of the storage tank. Fall prevention and the like can be reinforced.

  Hereinafter, the best mode for carrying out the invention will be described with reference to the drawings.
