Description

  The present invention relates to a rainwater extraction device that is attached to a vertical shaft and takes out rainwater to the outside.

  Conventionally, as shown in FIG. 11, a vertical rainwater draining device 50 that is attached between an upper vertical rail 2 and a lower vertical rail 3 and takes out rainwater to the outside has been proposed (see Patent Document 1).

  However, in the downpipe rainwater extraction device 50 configured as described above, when the amount of rainwater flowing through the upper downpile 2 is large, if the protruding length of the cylinder 57 is long, the amount of rainwater received by the partition portion 55 is large. The portion cannot exceed this cylinder 57. Therefore, there has been a problem that the vertical rainwater extraction device 50 overflows with rainwater unless most of the large amount of rainwater can exceed the cylinder 57.

  Further, in the vertical rainwater draining device 50 having the above-described configuration, when the amount of rainwater flowing through the upper vertical rail 2 is small, if the protruding length upward of the cylindrical body 57 is short, a large amount of rainwater received by the partition portion 55 is obtained. The part easily exceeds the cylindrical body 57. Therefore, there has been a problem that a sufficient amount of rainwater cannot be taken out if most of the little rainwater easily exceeds the cylinder 57 in this way.

  Therefore, an object of the present invention is to provide a downpipe rainwater extraction device that can take out an appropriate amount of rainwater to the outside in accordance with the amount of rainwater flowing through the upper downpipe.

  In order to solve the above problems, the present invention provides a water intake joint tube that allows communication between an upper vertical rod and a lower vertical rod, and rainwater that communicates with the water intake joint tube and extracts rainwater flowing through the water intake joint tube to the outside.

An adjustment cylinder is provided in the partition portion so as to communicate with the through hole.

  Moreover, it is preferable that the said adjustment cylinder is selected from the some cylindrical bodies from which the protrusion length above the said partition part differs.

  Or it is preferable that the said adjustment cylinder is a movement cylinder fitted by the said through-hole so that it could move up and down freely.

  The downpipe rainwater extraction device of the present invention can take out an appropriate amount of rainwater to the outside in accordance with the amount of rainwater flowing through the uppipe.

  Hereinafter, an example of an embodiment of the present invention will be described with reference to the accompanying drawings.

  As shown in FIG. 3A, the downpipe rainwater take-out device 1 of the first embodiment is attached between the upper downpowder 2 and the downpipe 3 and is one of the rainwater flowing from the uppipe 2. The part is taken out to the outside. The drainage hose 11 is connected to the vertical seismic rainwater extraction device 1, and this extraction hose 11 is connected to a rainwater storage tank (not shown) installed outside. The upper vertical fence 2 and the lower vertical fence 3 are obtained by dividing one vertical fence extending from the roof toward the ground into upper and lower parts. The upper shaft 2 is connected to the eaves that collects and flows rainwater that has fallen on the roof.

  As shown in FIG. 3 (a), the vertical rainwater take-out device 1 communicates with a cylindrical water intake coupling tube 4 that allows the upper vertical rod 2 and the lower vertical rod 3 to communicate with each other, and the water intake joint tube 4. The rain water extraction part 5 extracts the rain water flowing through the water intake joint cylinder 4 to the outside. The water intake joint cylinder 4 and the rainwater extraction portion 5 are integrally formed of resin. In addition, the joint pipe 4 for water intake and the rain water extraction part 5 may be formed and connected separately.

  As shown in FIG. 2, the rainwater extraction portion 5 has a U-shaped wall surface 12 with a part of the outer periphery of the joint tube 4 having a circular plane cross section projecting outward, and a bottom of the wall surface 12. An outer shell is formed from a bottom surface 13 formed and a lid 14 that is detachably attached to an upper portion of the wall surface 12. The bottom surface 13 and the lid 14 are each formed in a semi-elliptical shape. The bottom surface 13 is provided with an extraction hole 15 penetrating vertically, and a cylindrical extraction tube 16 protruding downward is formed from the bottom surface 13 around the periphery of the extraction hole 15. A pair of projecting pieces 17 project upward from the end of the bottom surface 13 on the side of the water intake coupling cylinder 4. The pair of projecting pieces 17, 17 are formed with a gap therebetween, and the rainwater flow path from the water intake joint cylinder 4 to the rainwater extraction part 5 is formed between the pair of projecting pieces 17, 17. The pair of projecting pieces 17 and 17 are each formed integrally with the wall surface 12.

  A filter (not shown) is attached to the rainwater extraction portion 5, and dust in the rainwater flowing from the water intake joint tube 4 to the extraction hole 15 of the rainwater extraction portion 5 can be removed. This filter can be replaced by removing the lid 14 from the rainwater extraction part 5.

  As shown in FIG. 5A, one end of the takeout hose 11 is connected to the takeout tube 16 of the rainwater takeout unit 5. Specifically, as shown in FIG. 5B, the inner peripheral surface of one end of the extraction hose 11 is externally fitted to the outer peripheral surface of the extraction cylinder 16, and the fastener 18 is further externally fitted to the outer periphery of the externally fitted portion. Thus, one end of the take-out hose 11 is fixed to the take-out cylinder 16 so that the inside communicates.

  As another connection method, there is a method in which one end of the extraction hose 11 is connected to the inside of the extraction cylinder 16 as shown in FIG. In this case, as shown in FIG. 6 (b), a spiral projection 19 is formed over the entire outer peripheral surface of the take-out hose 11, and one end of the take-out hose 11 is fitted into the take-out cylinder 16. An annular fitting groove 20 that opens downward is formed. A spiral groove 21 that fits the protrusion 19 is formed on the outer peripheral surface of the fitting groove 20 over the entire circumference, and the inner circumference of the extraction hose 11 is formed on the inner peripheral surface of the fitting groove 20. A contact surface 22 that contacts the surface is formed.

  When one end of the take-out hose 11 is inserted into the fitting groove 20 having the above configuration while rotating, one end of the take-out hose 11 has an outer peripheral surface while the inner peripheral surface is in contact with the contact surface 22 of the fitting groove 20. The spiral projection 19 is fitted into the spiral groove 21 of the fitting groove 20. In this way, one end of the take-out hose 11 is connected while being held inside the take-out cylinder 16. Therefore, it is not necessary to bother fixing with the fastener 18 as in the case of external fitting. Moreover, since it can connect by only inserting while rotating, the time which a connection requires can be shortened compared with the case where it carries out external fitting. In addition, the cut surface of the end portion of the take-out hose 11 is usually difficult to cut straight and clean, and is often cut obliquely. However, the internal cut does not expose the oblique cut surface. The connection status looks beautiful. In addition, the shape which fits the extraction hose 11 and the extraction cylinder 16 is not limited to the illustrated shape.

  Moreover, it is preferable to fix the vertical dredge rainwater extraction apparatus 1 to the building wall 23 as shown in FIG.7 (c). As shown to Fig.7 (a), the adhering part 24 protrudes from the outer peripheral surface of the joint cylinder 4 for water intake. The fixing portion 24 is formed by two plate-like protrusions 25, 25 that protrude from the outer peripheral surface of the water intake coupling tube 4. Two screw holes 26 are provided through the two plate-like protrusions 25, 25 respectively. The fixing portion 24 is fixed to the building wall 23 with screws, bolts, or the like via fixing connectors such as a T-shaped foot 27 shown in FIG. 7 (b1) and an L-shaped foot 28 shown in FIG. 7 (b2). The Each of the T-shaped foot 27 and the L-shaped foot 28 is provided with a plurality of screw holes. The T-shaped foot 27 and the L-shaped foot 28 are preferably, for example, generally commercially available hardware. The T-shaped foot 27 and the L-shaped foot 28 may be resin-molded.

  Further, as shown in FIG. 8, as a structure for fixing the vertical rainwater draining device 1 to the building wall 23, as shown in FIG. 8, the T-shaped protrusion fixing portion 29 in which the T-shaped foot 27 and the fixing portion 24 of FIG. 7 are integrated. It may be. The fixing portion 29 has two screw holes 30 in the plate-like portion at the tip. With this fixing portion 29, as shown in FIG. 7C, the work of fixing the T-shaped foot 27 and the fixing portion 24 with screws, bolts or the like is not required, so that the workability is improved. . Further, instead of the T-shaped foot 27, the L-shaped foot 28 may be integrated with the fixing portion 24.

  By fixing the vertical rainwater take-out device 1 to the building wall 23 through the fixing portion 24 or the fixed portion 29 described above, external force applied to the vertical rainwater take-out device 1 (strong wind, earthquake, person applying force by mistake, etc.) ) Can be increased. Of course, it is particularly effective to increase the resistance to external force when the upper vertical rod 2 and the lower vertical rod 3 are heavy. By fixing the downpipe rainwater take-out device 1 to the building wall 23 as described above, it is possible to prevent the downpipe rainwater take-out device 1 from being detached from the upper downpipe 2 and the down downpipe 3, and Moreover, it can prevent that the lower vertical gutter 3 and the vertical gutter rainwater extraction device 1 are damaged.

  The configuration of the water intake coupling tube 4 of this embodiment will be described in more detail.

  The water intake joint cylinder 4 has a cylindrical shape with a constant outer diameter, and as shown in FIG. 1 (a), is provided with an upper vertical rod connection cylinder portion 6 connected to the upper vertical rod 2 at its upper end, A lower vertical rod connecting tube portion 7 connected to the lower vertical rod 3 is provided at the lower end portion. Moreover, between the upper end part and the lower end part, the partition part 8 which partitions the inside of the joint cylinder 4 for water intake up and down is provided. The partition portion 8 is provided with a through hole 9 penetrating vertically. That is, the partition portion 8 is formed in a ring shape, and the outer periphery thereof is formed integrally with the inner peripheral surface of the water intake coupling tube 4. The partition portion 8 is located above the bottom surface 13 of the rainwater extraction portion 5.

  As shown in FIG. 2A, the upper vertical hook connecting cylinder portion 6 has a cylindrical shape in plan view. The upper vertical hook connecting cylinder portion 6 can be connected to the upper vertical hook 2 of various thicknesses by attaching a connecting member 31 described later. The upper vertical rod 2 having various thicknesses indicates that the inner diameter is larger than the outer diameter of the through hole 9 and the outer diameter is smaller than the inner diameter of the upper vertical rod connecting tube portion 6.

  For example, when the outer diameter of the upper vertical rod 2 is smaller than the inner diameter of the upper vertical rod connecting tube 6, as shown in FIGS. 3 (a) and 4 (a), the upper vertical rod 2 is connected via an annular connecting member 31. The hook 2 is connected to the upper vertical hook connecting tube portion 6. Here, the annular connecting member 31 is flexible and can be bent to connect the upper vertical rod 2 of various thicknesses to the upper vertical rod connecting tube portion 6. In addition, since the connection member 31 bends and fills the space between the upper vertical hook connecting cylinder portion 6 and the upper vertical hook 2, it also serves as a seal member. Further, when the outer diameter of the upper vertical rod 2 is substantially the same as the inner diameter of the upper vertical tube connecting tube portion 6, as shown in FIGS. 3 (b) and 4 (b), a ring-shaped seal member (not shown) The upper vertical gutter 2 is connected to the upper vertical gutter connecting cylinder 6 via.

  Further, as shown in FIG. 1 (a) and FIG. 2 (c), the lower vertical rod connecting cylinder portion 7 has a lower end portion (hereinafter referred to as “connecting outer cylinder 32”) of the intake pipe 4 and a partition. It is comprised from the two cylinders (The inner cylinder 33 for drainage, and the middle cylinder 34 for connection) which protrude below from the part 8. FIG. These three cylinders are formed concentrically, and are lined up with a drain inner cylinder 33, a connecting middle cylinder 34, and a connecting outer cylinder 32 in order from the inside. The drain inner tube 33 protrudes downward from the partition 8 at the periphery of the through-hole 9, and the connecting middle tube 34 extends downward from the partition 8 between the drain inner tube 33 and the connecting outer tube 32. It is something that protrudes.

  The lower vertical rod connecting cylinder portion 7 can connect the lower vertical rod 3 having various thicknesses via a seal member (not shown). The lower vertical rod 3 having various thicknesses indicates that the inner diameter is larger than the outer diameter of the draining inner cylinder 33 and the outer diameter is smaller than the inner diameter of the connecting outer cylinder 32. Actually, the inner peripheral surface of one end of the lower vertical rod 3 is connected to the outer peripheral surface of the drainage inner tube 33 or the outer peripheral surface of the connecting middle tube 34 via the seal member, or the lower vertical rod The outer peripheral surface of one end of 3 is connected to the inner peripheral surface of the connecting middle tube 34 or the inner peripheral surface of the connecting outer tube 32 via a seal member. In addition, the lower vertical rod 3 may be connected to the lower vertical rod connecting cylinder portion 7 without a seal member.

  That is, when the outer diameter of the lower vertical rod 3 is substantially the same as the inner diameter of the connecting middle cylinder 34, as shown in FIGS. 3 (a) and 4 (a), a ring-shaped seal member (not shown) is interposed. Thus, the lower vertical rod 3 is connected to the inner peripheral surface of the connecting middle cylinder 34. When the outer diameter of the lower vertical rod 3 is the same as the inner diameter of the connecting outer cylinder 32, as shown in FIGS. 3 (b) and 4 (b), a ring-shaped seal member (not shown) is interposed. The lower vertical rod 3 is connected to the connecting outer cylinder 32 of the lower vertical rod connecting cylinder portion 7.

  An adjustment cylinder 10 as shown in FIG. 1 (d) is attached on the partition portion 8 to the water intake coupling cylinder 4 having the above-described configuration. The adjustment cylinder 10 is a cylinder that protrudes upward from the partition portion 8 and can adjust its protruding length. In the present embodiment, the adjustment cylinder 10 includes a plurality of (three in this example) projecting lengths different from the partitioning portion 8 as shown in FIGS. 1 (b1), (b2), and (b3). One of the cylindrical bodies 35, 36, 37 is selected. In addition, the cylindrical body should just be plural, two may be sufficient, and three or more may be sufficient.

  The cylindrical bodies 35, 36, and 37 are configured by a cylindrical portion 38 and a flange portion 39, and the flange portion 39 projects outward from one end of the cylindrical portion 38. The cylindrical portion 38 has an inner diameter that is substantially the same as the diameter of the through hole 9. The flange portion 39 is formed in a ring shape, and has an outer diameter substantially the same as the outer diameter of the ring-shaped partition portion 8. When the cylindrical bodies 35, 36, and 37 are mounted on the partition portion 8, as shown in FIG. 1C, the tubular portion 38 and the through hole 9 communicate with each other, and the lower surface of the flange portion 39 is connected to the partition portion. 8 is in contact with the upper surface. 1C shows a state in which the cylindrical body 37 of FIG. 1B3 is mounted on the partition portion 8. FIG.

  The adjustment cylinder body 10 (any one of the cylindrical bodies 35, 36, and 37) having the above-described configuration is attached to the vertical rainwater draining device 1, and the vertical rainwater drainage device 1 is connected to the upper vertical rainwater 2 and the lower Connect to the vertical gutter 3. The rainwater flowing from the upper vertical rod 2 is temporarily received by the flange portions 39 of the cylindrical bodies 35, 36, and 37. At this time, a part of the rainwater received by the flange portion 39 flows into the through hole 9 through the cylindrical portion 38 and is drained to the lower vertical gutter 3, and the remaining rainwater flows between the pair of protruding pieces 17 and 17. Then, it flows into the rainwater extraction part 5 and is taken out to the outside.

  Here, one standard of which cylindrical body should be selected from the cylindrical bodies 35, 36, and 37 will be described.

  When there is a lot of rainwater flowing through the upper vertical fence 2 (when the thickness of the upper vertical fence 2 is thick, when there is a large amount of water in the eaves connected to the upper vertical fence 2, or when it is installed in a region with a lot of rainfall) ) Is attached with a cylindrical body 37 having a short upward projecting length. In this way, by attaching the cylindrical body 37 having a short upward projecting length, most of the rainwater once received by the flange portion 39 of the cylindrical body 37 is caused to exceed the cylindrical portion 38 and pass through the through hole 9. Can flow into. In other words, when the amount of rainwater flowing through the upper shaft 2 is large, the amount of rainwater that has flowed into the vertical rainwater extraction device 1 is increased and the amount of water taken out is reduced, so that most of the rainwater that has flowed in is reduced. It is possible to prevent the downpipe rainwater take-out device 1 from overflowing with rainwater by draining into the downpipe 3.

  In addition, when the amount of rain water flowing through the upper vertical fence 2 is small (when the thickness of the upper vertical fence 2 is thin, or when the amount of water in the eaves connected to the upper vertical fence 2 is small, it is installed in an area where the rainfall is low In such a case, a cylindrical body 35 having a long upward projecting length is attached. In this way, by attaching the cylindrical body 35 having a long upward projecting length, it is difficult for the rainwater once received by the flange portion 39 of the cylindrical body 35 to easily exceed the cylindrical portion 38, and this rainwater A part can be made to flow into the rainwater extraction part 5. In other words, when the amount of rainwater flowing through the upper vertical gutter 2 is small, the amount of rainwater that has flowed into the vertical drainage water take-out device 1 is reduced and the amount of water taken out is increased, so that the amount of rainwater that has flowed in is large. A part can be taken out to the rainwater extraction part 5.

  In addition, when there is much rainwater which flows through the upper vertical gutter 2 and there are few cases, if the cylindrical body 36 shown in FIG. 1 (b2) is selected in each case, the rainwater which has flowed into the vertical gutter rainwater extraction device 1 is drained. The amount of water to be taken out and the amount of water to be taken out can be adjusted to different amounts of water from when the cylindrical body 35 or the cylindrical body 37 is selected.

  As described above, any cylindrical body may be selected from the cylindrical bodies 35, 36, and 37 according to the amount of rainwater flowing through the upper vertical rod 2. Note that not only the amount of rainwater flowing through the upper vertical shaft 2 but also the amount of rainwater that is desired to be taken out is a guide for selection.

  As shown in FIG. 1 (d), two gap forming projections 40 protruding upward are formed side by side in the radial direction from a part of the flange portion 39 of the cylindrical bodies 35, 36, and 37. The inner gap forming protrusion 40 is integrated with the cylindrical portion 38. As shown in FIG. 4A, the inner gap forming projection 40 is formed under the upper vertical rod 2 when the thin upper vertical rod 2 is inserted deep into the upper vertical rod connecting tube portion 6. Abuts against the end face. Further, as shown in FIG. 4 (b), the outer gap forming projection 40 is formed so that the upper vertical rod 2 having a large diameter is inserted into the upper vertical rod connecting cylinder 6 to the back of the upper vertical rod 2. Abuts the lower end surface.

  As described above, the gap forming protrusion 40 is provided on a part of the flange portion 39 so that the lower end surface of the upper vertical rod 2 does not contact the flange portion 39, so that the upper vertical rod 2 forms the gap. Even when it is inserted until it comes into contact with the projection 40 for use, a gap can be formed between the lower end surface of the upper vertical rod 2 and the flange portion 39. Therefore, the rainwater flowing through the upper vertical gutter 2 can be taken out to the rainwater extraction part 5 through this gap. In addition, even if the upper vertical gutter 2 and the joint cylinder 4 for water intake are expanded or contracted due to a change in temperature or the like, the upper vertical gutter 2 may be connected in a state where it is not easily detached from the upper vertical gutter connecting cylinder portion 6. The connection may not be made in a state where the lower end is inserted until the lower end comes into contact with the gap forming protrusion 40.

  Here, as shown in FIG. 1B, the gap forming protrusions 40 of the cylindrical bodies 35, 36, and 37 have the same protruding length as the cylindrical portion 38. Therefore, the vertical gap between the lower end surface of the upper vertical rod 2 and the flange portion 39, which can be formed when the upper vertical rod 2 is inserted until it comes into contact with the gap forming projection 40, is the cylindrical body 35, 36, 37. It becomes the width according to the protrusion length of each cylinder part 38. FIG. That is, when the cylindrical body 35 having a long cylindrical portion 38 is selected, a large vertical gap can be provided between the lower end surface of the upper vertical rod 2 and the flange portion 39, so that rainwater is unlikely to cross the cylindrical portion 38. In addition, the flow path through which the rainwater flows can be widened, and most of the rainwater received by the flange portion 39 can be taken out to the rainwater extraction portion 5. In addition, when the short cylindrical body 37 of the cylindrical portion 38 is selected, since the vertical gap between the lower end surface of the upper vertical rod 2 and the flange portion 39 is narrow, the rainwater easily exceeds the cylindrical portion 38, and the rainwater Since the flowing channel is also narrow, most of the rainwater received by the flange 39 can be drained to the lower vertical gutter 3. As described above, even when the upper vertical rod 2 is inserted until it comes into contact with the gap forming projection 40, the selected cylindrical body (any one of the cylindrical bodies 35, 36, and 37) is used. Appropriate amount of rainwater can be taken out.

  Then, the vertical rainwater extraction apparatus 1 of 2nd embodiment is demonstrated. About the structure corresponding to the vertical dredge rainwater extraction apparatus 1 of 1st embodiment, the same code | symbol is attached | subjected on drawing, description is abbreviate | omitted, and only a different structure is demonstrated in detail.

  As shown in FIG. 9, the vertical rainwater take-out device 1 according to the present embodiment includes a drainage inner cylinder 33 that protrudes downward from the partition portion 8 at the periphery of the through-hole 9 according to the first embodiment. It also protrudes upward. Further, the adjusting cylinder 10 that protrudes upward from the partition portion 8 and can adjust the protruding length is a moving cylinder 41 that is fitted on the inner peripheral surface of the drainage inner cylinder 33 so as to be movable up and down. ing. Here, the inner diameter of the inner cylinder 33 for drainage and the diameter of the through hole 9 are the same, and a part of the inner peripheral surface of the inner cylinder 33 for drainage is the through hole 9. That is, the movable cylinder 41 is also fitted into the through hole 9 so as to be movable up and down.

  The movable cylinder 41 has a cylindrical shape, and as shown in FIGS. 9 and 10B, a spiral protrusion 42 projects from the lower portion of the outer peripheral surface. A spiral groove 43 that fits into the spiral protrusion 42 is formed in the lower portion of the inner peripheral surface of the drainage inner cylinder 33. A ring-shaped seal member 44 is attached to the upper part of the inner peripheral surface of the drainage inner cylinder 33, and this seal member 44 comes into contact with the upper part of the outer peripheral surface of the movable cylinder 41 so that water can be stopped. .

  The movable cylinder 41 is rotated inside the drainage inner cylinder 33 so that the spiral protrusion 42 on the outer peripheral surface is fitted in the spiral groove 43 on the inner peripheral surface of the drainage inner cylinder 33, The screw is moved back and forth so that it can move up and down from the upper end position shown in FIG. 9 (a) to the lower end position shown in FIG. 9 (b). Here, in a state where the movable cylinder 41 is located at the lower end position, the upper end surface of the movable cylinder 41 is substantially flush with the upper end surface of the drainage inner cylinder 33. If the movable cylinder 41 is movable up and down along the inner circumferential surface of the drainage inner cylinder 33, the configuration of the outer circumferential surface of the movable cylinder 41 and the inner circumferential surface of the drainage inner cylinder 33 is as described above. It is not limited to this configuration, and other fitting structures may be used. Moreover, the movable cylinder 41 may be formed to be movable further upward than the upper end position shown in FIG.

  The adjustment cylinder 10 (movable cylinder 41) having the above-described configuration is attached to the downpipe rainwater extraction device 1, and the downpipe rainwater extraction device 1 is connected between the upper downpipe 2 and the downpipe 3. Rainwater flowing in from the upper vertical rod 2 is temporarily received by the partition portion 8 between the outer peripheral surface of the drainage inner tube 33 and the inner peripheral surface of the water intake joint tube 4. At this time, a part of the rainwater received by the partition portion 8 flows into the through hole 9 through the drainage inner cylinder 33 and the movable cylinder 41 and is drained to the lower vertical gutter 3, and the remaining rainwater is a pair of protrusions. It passes between the pieces 17 and 17 and flows into the rainwater extraction part 5 and is taken out to the outside.

Note that not only the amount of rainwater flowing through the upper vertical gutter 2 but also the amount of rainwater that is desired to be taken out is a measure of the protruding length.

  Further, in the present embodiment, as shown in FIGS. 9 and 10, two gap forming projections 40 that protrude upward are formed side by side in a radial direction from a part of the partition portion 8. The upward protruding length of the gap forming projection 40 is substantially the same as the upward protruding length of the drainage inner cylinder 33 from the partition portion 8. As described above, the gap forming protrusion 40 is provided on a part of the partition portion 8 so that the lower end surface of the upper vertical rod 2 does not contact the partition portion 8. Even when it is inserted until it comes into contact with the protrusion 40, a gap is formed between the lower end surface of the upper vertical rod 2 and the partition portion 8. Therefore, the rainwater flowing through the upper vertical gutter 2 can be taken out to the rainwater extraction part 5 through this gap.

(Effect of each embodiment)
A vertical rainwater take-out device 1 according to the first and second embodiments is connected to a water intake joint cylinder 4 for communicating an upper vertical firewood 2 and a lower vertical firewood 3, and a water intake joint cylinder 4. And a rainwater extraction section 5 for taking out rainwater flowing through the outside. The intake pipe 4 is provided with an upper vertical hook connection cylinder 6 at the upper end, a lower vertical pipe connection pipe 7 at the lower end, and the inside of the intake pipe 4 is vertically moved between the upper end and the lower end. The partition part 8 is divided. The partition part 8 is provided with a through hole 9 penetrating vertically. And the adjustment cylinder 10 which protrudes upwards from the partition part 8 and can adjust the protrusion length is provided in the partition part 8 so as to communicate with the through hole 9.

  By adopting such a configuration, when the amount of rainwater flowing from the upper vertical rod 2 is large, the protruding length of the adjustment cylinder 10 upward is shortened, and the lower vertical rod extends beyond the adjustment cylinder 10. It is possible to increase the amount of rainwater drained to 3 and prevent the vertical rainwater drainage device 1 from overflowing with rainwater. When the amount of rainwater flowing from the upper vertical gutter 2 is small, the protruding length of the adjustment cylinder 10 upward is increased, and the rainwater drained to the lower vertical gutter 3 beyond the adjustment cylinder 10 The amount of rainwater taken out to the rainwater extraction part 5 can be increased.

  As described above, by adjusting the protruding length of the adjustment cylinder body 10 above the partition portion 8 to an optimum length, the downpipe rainwater extraction device 1 can adjust the amount of rainwater flowing through the uppipe 2. In addition, rainwater with an appropriate amount of water can be taken out.

  Further, in the vertical rainwater take-out device 1 of the first embodiment, the adjustment cylinder 10 is selected from a plurality of cylindrical bodies 35, 36, 37... With different projecting lengths upward from the partition portion 8. It is characterized by that.

  By adopting such a configuration, a cylindrical body having an optimal protruding length is formed in accordance with the amount of rainwater flowing through the upper vertical gutter 2, and a plurality of cylindrical bodies having different protruding lengths above the partition portion 8. Choose one from 35, 36, 37 ... For example, when the amount of rainwater flowing from the upper vertical gutter 2 is large, the tubular body 37 having a short upward projection length is selected, and when the amount of rainwater flowing from the upper vertical gutter 2 is small, the cylindrical body 37 is moved upward. It is only necessary to select the cylindrical body 35 having a long protruding length. By simply selecting in this way, the protruding length of the adjustment cylinder 10 upward from the partition portion 8 can be easily adjusted to the optimum length, and according to the amount of rainwater flowing through the upper vertical rod 2, Appropriate amount of rainwater can be taken out.

  Moreover, in the vertical rainwater extraction apparatus 1 of 2nd embodiment, the adjustment cylinder 10 is the movement cylinder 41 engage | inserted by the through-hole 9 so that the vertical movement was possible.

  With such a configuration, when the amount of rainwater flowing from the upper vertical gutter 2 is large, the movable cylinder 41 is moved downward so that the upward protruding length is shortened. When the amount of rainwater flowing in is small, the movable cylinder 41 may be moved upward so that the upward protruding length is increased. Therefore, there is no need to prepare a plurality of adjustment cylinders 10, and the protruding length of the adjustment cylinder 10 above the partition portion 8 is adjusted to an optimum length simply by moving the movable cylinder 41 up and down. In accordance with the amount of rainwater flowing through the upper vertical gutter 2, rainwater having an appropriate amount of water can be taken out.

(Example of change)
In the first and second embodiments, the gap forming projections 40 are formed on a part of the flange portion 39 or the partition portion 8, but they may be provided at a plurality of locations instead of a part thereof.

  In the first and second embodiments, the two gap forming protrusions 40 are formed side by side in the radial direction, but may be a single gap forming protrusion 40 extending in the radial direction. In this case, the strength of the gap forming projection 40 is increased and molding is easy.

  Further, in the second embodiment, the drainage inner cylinder 33 protrudes above and below the partition portion 8, but, just like the drainage inner tube 33 of the first embodiment, only below the partition portion 8. It may be protruding.
