Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a front view explanatory view showing a rainwater storage and supply system in which a rainwater purification guide device according to the present embodiment is used, FIG. 2 is a plan view showing the vicinity of a storage tank of the rainwater storage and supply system, and FIG. It is a left view which shows the water storage tank periphery of a supply system.

  4 is an enlarged front view showing a part of the rainwater purification guide apparatus according to the present embodiment in section, FIG. 5 is a plan view showing a part of the rainwater purification guide apparatus, and FIG. 6 is the rainwater purification guide. It is front view explanatory drawing which shows a mode that a part of guide apparatus was open | released.

  1 to 3, reference numeral 100 denotes a rainwater purification guide apparatus according to the present embodiment, 101 denotes a water storage tank, and 102 denotes a water supply pump. The rainwater storage and supply system including the rainwater purification guide device 100 and the water storage tank 101 is installed and used, for example, in a detached house.

  The rainwater purification guide apparatus 100 includes a standing pipe line 1 fixed in the vicinity of the water storage tank 101 via an arbitrary support means. The vertical pipe 1 is formed of, for example, a polyvinyl chloride pipe having a nominal diameter of about 75A, and rainwater that has fallen on a water collection point such as the roof top surface of a detached house passes from the upper side through a gutter or a water pipe by gravity. It is supposed to flow in.

  A purification unit 2 is formed in the vertical pipe 1, and the purification unit 2 includes a bucket-type filtration unit 3 and a cyclone-type separation mechanism unit 4.

  As shown in FIGS. 4 to 6, the bucket-type filtration unit 3 surrounds the filtration bucket 5 positioned in the standing pipe 1 and the outer periphery of the filtration bucket 5 in a liquid-tight manner and stands up the pipe 1. And a tubular surrounding member 6 forming a part in the longitudinal direction. The filtration bucket 5 has a filtration surface composed of a bottom surface portion 5a and a peripheral surface portion 5b, and a large number of through holes as filtration eyes are formed in the filtration surface, and almost the entire upper surface is opened, and in use In this case, an upright is positioned between the upright pipe portion 1a located on the upper side and the upright pipe portion 1b located on the lower side, and the bottom surface 5a is located on the lower side. The bottom surface portion 5a is fitted into and supported by a circular recess 7a formed on the upper surface of the vortex generating guide 7 which is arranged in a posture and is fixed to the upper end of the lower vertical pipe 1b. ing. At this time, the standing pipe line 1a located on the upper side is smaller in diameter than the diameter of the opening on the upper surface of the filtration bucket 5, and is arranged substantially concentrically with the opening.

  On the other hand, the tubular surrounding member 6 includes a peripheral wall portion 6a formed of a pipe member having a nominal diameter of about 150A, an annular upper surface plate 6b fixed to the upper end surface of the peripheral wall portion 6a, and an inner hole portion of the upper surface plate 6b. And a cylindrical member 6c that is fixed so as to rise upward and is externally fitted to the peripheral wall portion of the upper standing pipe 1a so as to be movable up and down. A nut member 8 is fixed to the peripheral wall portion of the cylindrical member 6c. At the same time, the nut member 8 is configured to be screwed with a fastening bolt 8a in which a knob for manual operation is formed. When rainwater flows down in the vertical pipe 1, the tubular surrounding member 6 is lowered to the lowest position in the vertically movable range as shown in FIG. 4, and the lower end is densely formed around the outer periphery of the vortex generating guide 7. The outer fitting state is achieved, and the fastening bolt 8a is turned to the fastening side, and is operated in a state of being fixed to the standing pipe 1 in the same body shape and in a substantially liquid-tight state. Therefore, the tubular surrounding member 6 functions as a part of the standing duct 1.

The vortex generating guide 7 has an annular shape as shown in FIG. 5 and is in the direction of an arrow inclined at a certain angular interval around the center line a1 of the vertical duct 1 by several tens of degrees in plan view with respect to the radial direction. The water flow groove 7b for generating the water flow a2 is formed.
Each water flow groove 7b generates a water flow that tends to follow the inner wall surface of the lower vertical pipe 1b when rainwater flows in from the upper side and flows out to the lower side. It functions to generate a vortex that turns in the vicinity in the direction of the arrow a2 around the center line a1.

  The cyclonic separation mechanism unit 4 is located immediately below the vortex generation guide 7 and functions as a vortex generation space. The vertical pipe portion 1b having a nominal diameter of about 125A, and extends downward continuously from the vertical pipe portion 1b. In addition, an inverted conical standing pipe portion 8 and a rainwater outflow pipe 9 for allowing rainwater in the standing pipe 1 to flow out to the water storage tank 101 are provided.

  The inverted conical standing pipe portion 8 has the uppermost portion equivalent to the diameter of a pipe having a nominal diameter of 125A and the lowermost portion equivalent to the diameter of a pipe having a nominal diameter of 75A, and has a total length of, for example, 250 mm to 450 mm. It is made with the length within. At this time, a drainage outflow hole 10 that is a hole for discharging sand or the like and having a diameter that does not block the sand (for example, about 3 to 5 mm) is formed inside the lowermost part. . In the inside of the inverted conical standing pipe portion 8 configured as described above, contaminants such as sand act on the centrifugal force based on the rotational movement accompanying the vortex generated by the vortex generating guide 7 and the contaminant. Because the gravity sinks while rotating along the inner peripheral surface of the inverted conical standing pipe section 8, the inverted conical standing pipe section from the upper part of the exclusion outflow hole 10 to the exclusion outflow hole 10 is reached. It is preferable that the inner peripheral surface of 8 is gradually reduced in diameter.

  The rainwater outflow pipe 9 is formed so as to flow rainwater in the upper part of the inverted conical standing pipe section 8 or in the vicinity of the center position somewhat above it, and on the downstream side of the vortex generating guide 7. The lateral pipe part 9 a located within the height range that is the upper part of the conical standing pipe part 8 is fixed to the peripheral wall part of the inverted conical standing pipe part 8. At this time, the rainwater outflow pipe 9 is positioned downward from the vortex generation guide 7 by a distance of, for example, 0.8 times or more the diameter of the vertical pipe section 1b, and the vertical inflow start end from which rainwater flows in from below. In this way, the degree to which the growth of the vortex generated by the vortex generating guide 7 is hindered by the rainwater outflow pipe 9 is suppressed, and contaminants such as sand are contained in itself. As a result of this revolution, the inverted conical standing pipe portion 8 is moved to the inner peripheral side, so that the rainwater flowing into the inflow start end portion 9b is unlikely to attract contaminants such as sand into the rainwater outflow pipeline 9. .

  Reference numeral 11 denotes a rainwater guide pipe connected to the rainwater outflow pipe 9, which guides rainwater flowing out from the rainwater outflow pipe 9 to the water storage tank 101. Reference numeral 12 denotes a drainage pipe having a nominal diameter of about 75A, which is communicated with the drainage outflow hole 10 and allows rainwater flowing out from the drainage outflow hole 10 and contaminants such as sand contained therein to flow down to other places.

  The inside of the drainage pipe 12 and the standing pipe part 1a on the upstream side of the filtration bucket 5 are communicated with each other by a bypass pipe 13 having a nominal diameter of 50A. The bypass pipe 13 functions as an overflow pipe that causes the rainwater to flow down into the drainage pipe 12 when rainwater stays in the standing pipe portion 1 a due to the filtration bucket 5 being closed.

  Accordingly, the bypass pipe 13 has a passage structure in which rainwater does not easily flow into the bypass pipe 13 in a state where the rainwater does not stay in the vertical pipe portion 1a. Is provided with a deformed cheese joint 14 in the middle of the length of the standing pipe portion 1a, and the branch pipe 14a of the deformed cheese joint 14 is extended.

  The water storage tank 101 is made of a resin material and has a capacity of, for example, about 500 liters to 1000 liters. A pump mounting seat 15 is formed on the upper surface and is covered with a lid 16 so as to be openable. A large opening is formed, and a rainwater inlet 17 to which the rainwater guide pipe 11 is connected is formed on the left side surface.

  A water suction pipe 19 extends from a water suction port 18 formed on the left side of the water supply pump 102 and is led to the bottom inside the water storage tank 101 through an opening on the upper surface of the water storage tank 101. Are provided with two standard discharge ports 20a and 20b, and one preliminary discharge port 20c is provided on the back side. Any one of these discharge ports 20a, 20b and 20c is put into use, and The used one is closed by a plate member or the like.

  A water reduction detection device 21 is disposed on the upper surface of the water storage tank 101, and a float which is a detection main part 21 a of the water reduction detection device 21 is introduced inward through the opening on the upper surface of the water storage tank 101. For example, when the water level in 101 becomes equal to or lower than a specific level b1, the water reduction detection device 21 detects the state electrically, generates a signal, and transmits the signal to the electric control unit and the alarm generation unit of the water supply pump 102. Yes.

  The electric control unit stops the electric drive unit of the water supply pump 102 by transmitting the signal of the water reduction detection device 21 and also detects the water reduction detection device 21 when the water level in the water storage tank 101 becomes higher than a specific level. The generated signal disappears, and the feed water pump 102 is returned to an operable state.

Further, a tap water supply port 22 connected to a water pipe (not shown) is formed on the right side surface of the water storage tank 101, and a float valve 23 is provided inside the water storage tank 101 of the tap water supply port 22. . The float valve 23 detects the water level of the water storage tank 101 with the float 23a, and closes the valve portion 23b when the water level becomes higher than the specific level b2, and opens it when the water level becomes lower than the specific level b2. It works. Reference numeral 24 denotes an overflow port, and the water in the water storage tank 101 overflows when the water level in the water storage tank 101 becomes a certain level higher than the specific level b2.
In addition, 25 is a power cable of the water supply pump 102, and 26 is a drain outlet of the water storage tank 101.

Next, the handling and operation of the above-described rainwater storage and supply system will be described.
Power is supplied from the power cable 24 so that the water supply pump 102, the water reduction detection device 21 and the like can be operated. The tap water supply port 22 is connected to a water pipe via a stop valve (not shown).

  When rain starts under this condition, rainwater is received at water collection points such as the top surface of the roof, collected in a trough (not shown), and then flows down in the vertical pipe 1 by gravity. This rainwater does not stay in the standing pipe 1 more than a certain amount unless the filter eyes of the filter bucket 5 are blocked by dead leaves, and therefore rainwater does not flow into the bypass pipe 13. Absent.

  Rainwater that has reached the filtration bucket 5 is sprinkled with relatively large dust, such as dead leaves, in the filtration bucket 5 through a filter mesh made up of relatively large groups of through holes formed on the side circumferential surface and bottom surface of the filtration bucket 5. Taken. After the relatively large dust is removed in this way, the rainwater reaches the vortex generation guide 7 and stays here somewhat, and the vortex generation guide 7 covered with the bottom surface portion 5a of the filtration bucket 5 flows. It flows downward in the arrow direction a2 through the groove 7b. The water flow in the arrow direction a2 through each water flow groove 7b reaches the inverted conical vertical pipe portion 8 through the vertical pipe portion 1b, and a part of the rainwater reaching here is discharged from the drainage outflow hole 10 to the discharge pipe. The rainwater flows out into the channel 12 and other rainwater gradually accumulates, and after a certain period of time related to the outflow rate from the discharge channel 12, a stormwater outflow tube in the inverted conical standing pipe portion 8 passes. When a certain level higher than that of the road 9 is reached, it begins to flow outward through the rainwater outflow pipe 9.

  For example, the initial rainwater from the start of the rain until the time of several tens of minutes elapses is extremely dusty and often acidic due to the influence of air pollution. By the time the fixed time elapses, the drained outflow hole 10 flows into the drain pipe 12 and does not flow into the water storage tank 101.

  Even after rainwater begins to flow into the water storage tank 101 through the rainwater outflow pipe 9, if rain with a certain amount of rainfall per hour or more continues, the rainwater flowing into the vertical pipe 1 is passed through the purification section 2. It continues to flow into the water storage tank 101 through the rainwater outflow pipe 9 while being purified. When such an inflow continues, the rainwater that has passed through the vortex generation guide 7 flows downward and turns into a steady vortex while swirling around the center line a1 in the vertical pipe portion 1b. The rainwater located at the center of a certain depth is changed in the flow direction to the upper side and flows into the vertical inflow start end portion 9 b of the rainwater outflow pipe 9. Such a flow of rainwater into the inflow start end portion 9b contributes not to disturb the vortex flow in the inverted conical standing pipe portion 8.

  Since the rainwater that has reached the inverted conical standing pipe portion 8 has already been removed by the filtration bucket 5 with relatively large dust, the dust mixed therein is mainly composed of relatively small sand or soil. Become. These sand and soil are given centrifugal force by the rotation of the vortex generated inside the standing pipe portion 1b and the inverted conical standing pipe portion 8, and gravity acts, so that the standing pipe portion 1b and the vicinity of the inner peripheral surface of the inverted conical standing pipe portion 8 receive a swirl force of rainwater and operate to sink by gravity while swirling, and when reaching the drainage outflow hole 10 or below a specific flow rate Then, it flows into the discharge pipe 12 together with the rainwater flowing down to the discharge pipe 12 side. Therefore, the rainwater flowing out through the rainwater outflow pipe 9 is the one from which contaminants such as sand and soil are removed.

  When the rain stops, rainwater does not flow into the standing pipe 1, so rainwater does not flow out from the rainwater outflow pipe 9 and does not flow into the water storage tank 101. Even after this state is reached, since the rainwater staying in the inverted conical standing pipe portion 8 continues to flow out from the drainage outflow hole 10, the inverted conical standing pipe is passed after an appropriate time (for example, about several tens of minutes). It is completely eliminated from within the road part 8. Thereby, the initial rain water at the time of the next rainfall is prevented from flowing into the water storage tank 101 by the above-described action.

  In the treatment of rainwater as described above, if too many dead leaves are brewed into the filtration bucket 5 and the filter eyes are closed, the rainwater cannot flow through the filtration bucket 5 and flow down. Rainwater stays in the upright pipe line 1a above 5. When the accumulated rainwater reaches the height of the branch pipe 14 a of the deformed cheese joint 14, the rainwater flows out directly into the drain pipe 12 through the bypass pipe 13. Therefore, the rainwater that has flowed into the vertical pipe 1 from the water collection point such as the top surface of the roof is drained without any trouble, and the drainage of the rainwater at the water collection point is not hindered.

  The filtration bucket 5 should be cleaned by regularly checking the clogging state of the filtration eyes. When cleaning is performed, the fastening bolt 8a is rotated by a manual operation force and then loosened, and then the state shown in FIG. As shown, the tubular surrounding member 6 is moved upward along the upper vertical pipe portion 1a, and under this state, the filtration bucket 5 is moved upward by several millimeters, and then laterally When the filtered bucket 5 thus taken out is returned into the standing pipe 1, the reverse of the above procedure is executed.

  After the water storage tank 101 becomes full, rainwater in the water storage tank 101 flows out from the overflow pipe 24 provided in the water storage tank 101. The clean rainwater collected in the water storage tank 101 is used by operating the water supply pump 102 and sprinkling water on the garden trees. At this time, when the rainwater in the water storage tank 101 falls below a specific level b1, water is reduced. The detection device 21 detects this, cuts off the power supply to the electric drive unit of the water supply pump 102 via the electric control unit, and activates an appropriate alarm (not shown) as necessary.

  When water supply by the water supply pump 102 is performed in a state where the amount of rainwater in the water storage tank 101 is insufficient, a stop valve (not shown) in the middle of the water supply line to the tap water supply port 22 is opened to supply tap water. The state is to be supplied to the mouth 22. Thus, tap water is supplied into the storage tank 101 through the tap water supply port 22 and the float valve 23, and when the water level in the storage tank 101 reaches the water supply stop level, the float valve 23 is closed and the tap water is supplied. The supply is stopped, and when the water level in the water storage tank 101 drops to the water supply start level, the float valve 23 is opened and the supply of tap water is started. Thereby, the water in the water storage tank 101 is always ensured within a certain level range.

In the above embodiment, the tubular surrounding member 6 is moved upward and the lateral outer side of the filtration bucket 5 is opened. However, the tubular surrounding member 6 is moved downward and the lateral side of the filtration bucket 5 is opened. It is possible that the direction will be open.
Further, the bypass pipe 13 may be a simple overflow pipe that is open to any other place without the end communicating with the discharge pipe 12.

  Further, a transparent material can be used for the material of the bypass pipe 13. In this way, too many dead leaves are dripped out in the filtration bucket 5 and the filtration eyes are blocked, and rainwater cannot flow down through the filtration bucket 5, so It becomes possible to easily confirm that rainwater stays in the standing pipe 1 a and that the rainwater exclusively flows out directly through the bypass pipe 13. As a result, the user can be prompted to clean the filtration bucket 5.

  FIG. 7: is the front view which showed a part of rainwater purification guide apparatus which concerns on another Example by the cross section, and FIG. 8 is front view explanatory drawing which shows a mode that a part of said rainwater purification guide apparatus was open | released. .

  In the present embodiment, the cyclone type separation mechanism section 4 constituting the purifying section 2 in the previous embodiment is changed, and the other portions are the same, so the same reference numerals are given.

  In the present embodiment, a small-diameter settling separation pipe 30 is provided at the center of the inverted conical standing pipe section 8 with the lowermost portion of the inverted conical standing duct section 8 being about half the nominal diameter (approximately 40 mm). It has a double vertical pipe structure. An upper portion of the settling separation pipe 30 is provided with a notch 34 obtained by obliquely cutting the pipe in order to introduce rainwater from the inverted conical standing pipe section 8. Is provided with an upper plate 35 that prevents the liquid from entering the settling separation tube 30. In addition, a water inlet of the lateral pipe portion 9a is fixed at a position facing the notch 34 in the upper part of the settling separation pipe 30. Further, the sedimentation separation pipe 30 extends from the center of the upright pipe portion 1b to the lowermost part of the inverted conical upright pipe portion 8, and a small hole 31 (diameter of about 3 mm) is provided in the lowermost part. And leads to the discharge line 12. On the other hand, two small holes 33 (diameter of about 3 mm) are provided diagonally between the inner surface of the pipe section 8 and the settling separation pipe 30 at the bottom of the inverted conical standing pipe section 8. It leads to the discharge line 12.

  FIG. 8 is a perspective view illustrating the structure of the upper part of the settling separation tube 30. The upper plate 35 is a circular plate larger than the outer shape of the settling separation tube 30, and the center position O ′ of the upper plate 35 is set on the settling separation tube 30 on the imaginary line P connecting the notch 34 and the lateral duct portion 9 a. It is eccentric to the notch 34 with respect to the center position O. For this reason, it has the part 35a covered from the upper board 35 above the notch 34, and it has prevented that rainwater directly penetrate | invades into the sedimentation-separation pipe | tube 30 directly from the bucket type path lower part 3. FIG.

  By adopting such a configuration, the rainwater first falls to the bottom of the inverted conical standing pipe portion 8 as indicated by the arrow P, and the water level gradually rises while being drained through the small hole 33, from above the sedimentation separation pipe 30. Water falls to the bottom of the tube. In the sedimentation / separation pipe 30, the water level rises while draining through the small holes 31, and reaches the lateral pipe part 9 a. As a result, the specific gravity separation structure in which the sand naturally settles within the volume of the inverted conical standing pipe portion 8 and the settling separation pipe 30 and only the purified water flows into the water storage tank.

  In this embodiment, the effect of centrifugal force and gravity due to the vortex in the inverted conical standing pipe section 8 is small due to the presence of the settling separation pipe 30 in comparison with the previous embodiment. The guide 7 may be omitted. As described above, the initial rainwater from the start of rainfall until the lapse of several tens of minutes, for example, is extremely mixed with dust and is often acidic due to the influence of air pollution. Therefore, in the present embodiment, rather than having the specific volume of the inverted conical standing pipe section 8 and the settling separation pipe 30 stay until the predetermined time elapses, sand and other specific gravity is naturally removed. It is effective in terms of settling.

  Further, in the present embodiment, the small holes 31 and the small holes 33 can be omitted.
