[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a device for storing rainwater, effectively utilizing the rainwater, and also obtaining emergency drinking water when water is cut off.

[0002]

[Prior art]

 The conventional rainwater storage device was constructed by installing a rainwater intake pipe 3 on the lower part of the side surface of the water storage tank 1 and a water supply pipe 5 on the upper part to discharge the residual water (refer to the publication No. 4-97959 of Kaikaihei). The tanks 1 are arranged one above the other and are connected by a water supply pipe 5. In addition, a water tank that is simply kept stationary (see Japanese Utility Model Laid-Open No. 1-75177), a band that fixes the outer circumference of the water tank to the outer wall of the building, and a frame that supports the water tank is fixed to the foundation ( There is, for example, Shoukaisho No. 5-220538).

[Issues to be solved by the invention]

 In the case of conventional rainwater storage tanks (structures in which the rainwater tank is buried in the ground and does not require a pump for pumping), the storage tank may simply be installed or placed on a concrete block or the like. It is a thing. In this type, since no earthquake countermeasures have been taken fundamentally, there is a case where the water storage cannot be effectively utilized as an emergency because the equipment may fall even if a small earthquake occurs, or the body may lean against it in an emergency and collapse. . Also, in the case of a type in which an iron rack is installed in the water storage tank, one water storage tank is relatively large (200 liters or more), and for each household, a simple water storage tank (after 100 liters) is installed It is not realistic considering diversity and mobility.

As described above, from the viewpoint of effectively utilizing the stored rainwater in an emergency, the conventional simple type rainwater storage device has been used only for sprinkling water to gardens, plants, etc. in normal times. Based on recent valuable experiences such as the Great Hanshin Earthquake, the present invention not only plays a role like a sewer on a daily basis, but it can also be used as an emergency water storage in an emergency so that it can be effectively used in the event of a disaster. Therefore, if the fresh water is such that it can be boiled in an emergency and used as a drink, the stored rainwater is also highly valuable as an emergency water. The purpose is to get.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, in the present invention, rainwater at the time of rainfall is discharged from the water supply port toward the bottom plate in the lower part of the water tank, and is accumulated in the sedimentation part formed on the lower side to the upper side. Independent water tanks that rise and are stored and pass through the drainage port at the top of the water tank as extra water to be drained to the outside are piled up and down as appropriate, and each water tank is connected by connecting pipes, and the overall water storage A rainwater storage device that seeks to increase its volume.

In addition, among the above-mentioned vertically stacked water storage tanks, at least one water storage tank is a rainwater storage tank in which a filter material is built-in, and the water storage tank in which the filter material is built-in is placed at the top, or A rainwater storage device that is located at the next stage to obtain more reliable fresh water.

Further, a receiving frame is provided on the upper surface of the lid of the water storage tank so that the bottom portion of the upper water storage tank can be inserted and placed in the receiving frame.

[0010]

[Action]

 In the rainwater storage device configured as described above, the rainwater that has fallen on the roof passes through the gutter and descends the vertical gutter from the top to drop onto the water receiving surface of the water sampler. Part of the rainwater is discharged through the water inlet through the water supply pipe toward the bottom plate from the water inlet facing the sedimentation part, which is the lower part of the uppermost water tank. At this time, the discharged water settles dust and the like in the rainwater in the sedimentation section at the bottom of the water tank, rises, flows into the drainage port at the upper part, passes through the connecting pipe, and the water supply port of the water tank at the lower stage. Flow into the water tank from and repeat the same flow as in the upper tank. Then, after passing through the drain pipe from the drainage port of the lowermost water storage tank, it is returned to the original vertical trough, combined with the spilled water that has slipped off from the water receiving surface of the above-mentioned water sampler, and flows down the vertical trough, It becomes a normal discharge state. After such circulation of rainwater and after rainfall, the inside of the water storage tank becomes static, and the dust and the like remaining in the water storage begins to settle, and finally clean water is stored. If a settling tank filled with a filter material is placed below the water tank, rainwater is filtered and stored as clean water in the settling tank, and the rainwater below the water tank containing the filter material is stored. The stage can store clean water without incorporating a filter medium.

In order to use rainwater in each water tank, it is sufficient to open the stopcocks at the intakes individually. In this case, sludge such as dust that has settled on the bottom plate of the settling section will be settled at the intakes. Since it is located on the upper part of the water tank, it does not wind up dust when it is taken in and is not discharged from the water tank to the outside.

To stack each water tank, insert the bottom of the next water tank into the receiving frame on the top surface of the first water tank placed horizontally, and place the bottom of the next water tank, The outlet and the outlet of the upper drainage port may be connected by a connecting pipe. By repeating these operations and connecting the water supply pipe of the best water tank to the water sampler, the stacking is completed.

Further, if the water storage tanks are simply stacked, the higher the height, the worse the stability becomes. Therefore, one end of the fixing material is locked to an appropriate locking portion provided on the lid of the water storage tank, and the other of the fixing materials is locked. Hang the other end on the fixing member fixed to the fixed part that is the outer wall of the building, and pull it in the left-right direction or diagonally downward on both sides to fix it by tension. This process is repeated independently in each water tank to stabilize and fix the whole.

【Example】

 An embodiment will be described with reference to the drawings. In FIG. 1 and FIG. 2, a vertical gutter 14 mounted on a roof 11 of a building 1 and a vertical gutter 14 via an upper joint 13 are arranged. A water sampler 2 is interposed at an appropriate place in the vertical gutter 14, and the water sampler 2 and a connection pipe 41 in the upper water tank 3 are connected by a water supply pipe 40, and the connection pipe 41 stores water. It penetrates vertically inside the tank 3, and its upper end protrudes from the water storage surface 31 as a ventilation hole 42, and its lower end opens in the vicinity of the bottom plate 32 of the water storage tank 3 toward the bottom plate 32 to form a water supply port 43. ing. An intake port 33 is provided at a position higher than the water supply port 43, and a water stop plug 34 is attached to the tip of the intake port 33. Further, a settling section 5 is provided between the position of the bottom plate 32 at the lower end of the water storage tank 3 and the height position of the water intake port 33, and sediment such as dust and sludge discharged from the water supply port 43 is deposited on the upper surface of the bottom plate 32. It On the other hand, in the upper part of the water tank 3, the rainwater drainage port 44 is opened at a position where the water storage surface 31 is formed, and the rainwater drainage port 44 is connected to the drainage port 44 through a continuation pipe 47 to the outside of the water storage tank 3. 46 is connected, and the other end is connected to the inlet side of the connection pipe 41 of the lower water tank 3. The water supply port 43 at the lower end of the connection pipe 41 faces the inside of the open pipe 61 of the settling tank 7 housed in the lower settling section 5 of the water storage tank 3. The filter medium 6 is loaded around the perforated pipe 61, and the incoming rainwater advances into the water storage tank 3 through the opening of the perforated lid 71 on the upper surface of the settling tank 7, and drains the upper water storage surface 31. From the mouth 44, the continuous pipe 47 flows down, and through the drainage pipe 45, it returns to the original vertical gutter 14 and flows down in the drainage direction. In the figure, 35 is a lid of the water storage tank 3, and 36 is a stand for a concrete or the like which is horizontally finished so that the water storage tank 3 can be stably placed.

The water tank 3 shown in detail in FIGS. 2 and 3 has a shape different from that of the upper end portion 3a, the body portion 3b, and the bottom portion 3c. The upper end portion 3a is formed in a substantially vertical cylindrical shape, and the flange 35a of the lid 35 covers the outer periphery of the upper end portion 3a so as to cover the outer periphery thereof, and polluted water from the surroundings (water splashed by a car or the like from the road). It prevents the water tank 3 from being deformed due to the intrusion of water and the weight applied through the lid 35 (such as the weight of the other water tank 3 stacked on the lid 35). The body portion 3b has an inverted conical shape with its radius becoming narrower toward the lower side, and as shown in FIG. 5, the body portion 3b is stacked like a general flower pot so that the occupied space can be saved. doing . The bottom portion 3c is a hollow cylindrical portion having an outer peripheral surface, and as shown in FIG. 2, the bottom portion 3c forms a space as a sedimentation portion 5 in which deposits in the stored water can be easily sedimented and accumulated toward the bottom plate 32, and the outer wall is formed. It is made of a thick material, and is formed into a male inverted convex shape that can be inserted into the inside of the receiving frame 35b of the lid 35 so that the bottom plate 32 and the lid 35 can be placed in contact with each other.

2 and 3, the lid 35 of the water storage tank 3 has a flange 35a formed along the outer periphery of the upper end portion 3a of the water storage tank 3 on the outer peripheral side of the lower surface thereof, and the receiving frame 35b is provided on the upper surface of the lid 35. Is formed so as to project, and a female die into which the bottom portion 3c of the water storage tank 3 is inserted is formed inside the receiving frame 35b, and has a concave shape as a whole. Further, as shown in FIG. 4, since the receiving frame 35b is a concave female type, rainwater, fallen leaves and the like may be accumulated and become a source of generation of a blower. Therefore, it is convenient for long-term management if the drain holes 35c are appropriately provided so as not to impair the overall strength. Of course, the drainage hole 35c is not limited to a hole shape, and a U shape or the like may have an appropriate shape and number as long as the purpose can be achieved.

2 and 3, the receiving frame 35b of the lid 35 is provided with a suitable number of locking members 81. In FIG. 2, the locking portions 81 ... are metal hooks, the roots of which are formed in a screw shape, and are screwed and fixed to the receiving frame 35b. Then, one end of the wire which is the fixing member 8 is hooked on the hook-shaped locking portion 81, and the other end is attached to the outer wall of the building 1 which is the fixing portion 82 as shown in FIGS. 1 and 3. It is hung on the head of an anchor which is a fixed member 83 .. As shown in FIG. 1, FIG. 2 and FIG. 3, if the wire, which is the fixing member 8 ... Is pulled down to the left and right in the diagonal direction and the locking portion 81. This prevents the water tank 3 ... from being flipped up even in a direct earthquake such as an earthquake. There are many other methods for obtaining such a fixed state. For example, the locking portion 81 shown in FIG. 4 has a shape integrally formed with the receiving frame 35b, and the receiving frame 35b is slender (the outer surface of the receiving frame 35b in FIGS. In a state of being used as the stopper 81, that is, a shape narrower than the outer circumference of the collar 35a of the lid 35), the fixing material 8 such as a wedge, a wire, a band, and a string is simply wound around and is attracted to the fixing portion 82. Alternatively, the fixing may be performed by an appropriate fixing member 83.

In FIG. 2 and FIG. 3, when rainwater in the water tank 3 is required, the water stop plug 34 of the water intake 33 may be opened and water may be taken from the water intake hose 9 into a bucket or the like. Further, as shown in Fig. 3, when the water storage tanks 3 ... have three stages, the final intake can be done at one place by connecting the intake hoses 9 ... integrally with the connecting hoses 91 ... . Further, in the case of FIG. 3, the property of the water storage in the water storage tank 3 ... Immediately after the rainfall, since the water in the upper water storage tank 3 has a large amount of dust such as dust on the roof 11 flowing down, the transparency becomes low. Since the water stored in the water storage tank 3 at the stage is filtered by the settling tank 7, clear water can be obtained.

[0019]

[Effect of the invention]

 Since the present invention is configured as described above, it has the following effects.

A rainwater is a water storage device that circulates through the water tank 3 when it rains. In the water tank 3, the rainwater supply port 43 from the water supply pipe 40 is located at the lower part of the water tank 3. Each independent water storage tank 3 capable of storing rainwater, in which the bottom 3c of the water storage tank 3 is formed in the settling section 5 and the height of the water discharge port 44 is set as the optimum water storage height, is set appropriately. Since the water tanks 3 are piled up and down and the respective water storage tanks 3 are connected to each other by the connecting pipe 46, the installation area of one simple-type water tank 3 allows the water storage capacity of one multiple to be increased by stacking according to the installation conditions. can get. Moreover, this storage water is fresh water that is naturally replaced by fresh rainwater each time it rains. For example, approximately 80 liters of water can be stored in one cylindrical water storage tank 3 having a diameter of 50 cm and a height of 50 cm. At this level, the utility value is low on a daily basis, but by stacking these three steps, the total height is 150 centimeters, which can be lower than the height of an adult, while maintaining stability, while maintaining 240 liters. It is possible to obtain a water storage capacity of about 1, and the amount of water for about 1 cup of a normal bath will be a very effective water source in an emergency when combined with normal use. As for the stacking condition, for example, in the case of a detached house, it is possible to effectively use a place where the fence and the building are narrow and there is no pedestrian traffic.

Further, in the case of a rainwater storage device in which at least one water storage tank 3 among the above-mentioned vertically stacked water storage tanks 3 is provided with the filtration material 6, a water storage tank having the filtration material 6 When 3 is the uppermost stage, the rainwater becomes clean water in the uppermost water storage tank 3, so clean water can always be obtained from below and it can be effectively used. However, the filter medium 6 also becomes dirty quickly, so it is necessary to replace it regularly. Further, when the water storage tank 3 having the filter medium 6 is located below the uppermost step, the entire uppermost step serves as the water tank 3 for precipitating dust, dust, etc., and purification in the lower step is easy. Therefore, the second-stage water storage tank 3 can be used separately for fresh water, which is a relief. As a test, the water storage device with the above structure was activated for about one year, and at the initial stage of rainfall, the water in the upper tier and the water in the lower tier were sampled and inspected (1996). May 14, 2004, based on the Okayama Health Promotion Foundation "Water Quality Inspection Report"). As a result, all the chemical values were good in the upper row, but the chromaticity was evaluated as 10. Then, in the lower part, chromaticity was 0, and good results were obtained in all cases.

Further, the outer peripheral side of the lower surface of the lid 35 of the water storage tank 3 ... Is formed with a collar 35b that covers the upper end portion 3a of the water storage tank 3 from the outside, and a receiving frame 35b is provided on the upper surface of the lid 35 so as to project. Since the bottom part 3c of the upper water storage tank 3 can be inserted and placed in the receiving frame 35b, the water storage tank 3 can be used as a single body, but additional parts for stacking are not required and the stacking is easy and reliable. Then, it is aligned with the center of the lower water storage tank 3, and the upper water storage tank 3 can be stacked without shifting to the left and right, so that two-tier stacking and three-tier stacking are easy. Further, there is nothing that hinders the piping of the connecting pipe 46 that connects the upper and lower water storage tanks 3 and 3, and the piping is easy.

Further, since the locking portion 81 capable of locking one end of the fixing material 8 is provided at a proper position on the outside of the lid 35, the lid 35 can withstand the highest strength of the upper and lower seams. By locating the locking parts 81 ... at a location, there is little risk that the parts will come off or fall out first, and it is safe.

Further, the fixing member 8 is interposed between the locking portion 81 of the lid 35 and the stopper member 83 of the external fixing portion 82, and the water tanks 3 are vertically stacked as appropriate. .. are fixed individually, so that they can be fixed to the fixing part 82 at the top and bottom insertion parts of the water tanks 3 stacked one above the other, and at the joints and joints, and the fixation It is equivalent to fixing the tank 3 ... individually, and the fixing is secure as a whole. If the external fixed portion 82 is a structure having an earthquake-resistant structure, the water storage device can also withstand an earthquake, so it can be used very effectively as emergency water. Furthermore, the highly stacked water storage tanks 3 ... can obtain the same stability as the water storage tanks 3 below. Therefore, it is possible to stack the water tanks 3 ... at a desired height.
