Description

  The present invention relates to a rainwater extraction device.

  With the recent increase in awareness of water shortages and global environmental conservation, the idea of using rainwater as a resource has been recognized, and devices for collecting rainwater have been studied and simple devices have been proposed.

  For example, a cylindrical device attached to an appropriate position of the eaves that communicates with the eaves, a connecting cylinder that connects the upper eave and the lower eave, a connection cylinder that is connected to the connection cylinder, and a filter There has been proposed a rainwater dust removal and water intake device having a rainwater extraction tube portion in which is installed (see, for example, Patent Document 1). This rainwater dust removal water intake device is composed of a filter that removes dust such as leaves and insects by a net and filter media, and a lid that can be opened and closed is attached to the upper opening of the rainwater take-out tube portion in which the filter is installed. It is fixed.

By the way, Patent Document 2 proposes a rainwater flow path switching device for circulating rainwater flowing down from an upper ridge (A ridge) to a B ridge or C ridge located therebelow. In this device, a valve is arranged in the apparatus, and the rainwater flow path in the apparatus is changed by changing the inclination of the valve by manually pushing and pulling a wire connected to the valve from the outside of the apparatus. Rainwater is run from A to B 樋 or rainwater is run from A 樋 to C 樋.
Utility Model Registration No. 3129492 JP 2003-184136 A

  In the rainwater flow path switching device of Patent Document 2, rainwater is allowed to flow only in either one of the bottles B or C. Here, when B 樋 is connected to the drainage ditch and C 接 続 is connected to a rainwater reservoir for use in fire prevention water, watering plants, etc., for example, in the rainwater reservoir in winter, If you want to stop the rainwater supply to the rainwater storage tank to prevent the occurrence of problems such as damage to the rainwater storage tank due to the frozen water being frozen, drain the water by switching the valve so that the rainwater flows to B 樋Drain into the ditch. On the other hand, when it is desired to supply rainwater to the rainwater reservoir, the valve is switched so that rainwater flows through C 樋. At this time, as a matter of course, rainwater from A 樋 flows unilaterally to the rainwater storage tank via C 樋, and no rainwater flows into B 樋. Therefore, for example, when a rainwater reservoir that does not have a function to prevent overflow is adopted, the rainwater unilaterally flows into the rainwater reservoir, resulting in overflow of the rainwater reservoir and a new problem. There is a risk. For this reason, it is necessary to switch the valve each time so that the rainwater does not flow to C 樋 so that the water in the rainwater reservoir does not overflow. As described above, the rainwater flow switching device of Patent Document 2 is easy to switch the valve itself, but since it cannot adjust the flow rate of rainwater to C 樋, Depending on the amount of water used, the frequency of checking the amount of water stored in the rainwater reservoir and switching valves has been increasing, which has been a burden on the user.

  The present invention solves the conventional problems from the background as described above, can easily stop the removal of rainwater, and when removing rainwater, the rainwater extraction device that can control the amount of rainwater depending on the amount of rainfall It is an issue to provide.

  The rainwater extraction device of the present invention is characterized by the following.

  First, a connecting tube portion that connects the upper and lower rods, a rainwater discharge tube portion that is continuous with and integrated with the connection tube portion and that has an opening at the upper end, and covers the opening of the rainwater discharge tube portion The connecting cylinder part has a reservoir bottom plate that receives rainwater flowing down from the upper ridge and distributes it to the rainwater extraction cylinder part. The rainwater extraction cylinder part is distributed from the connection cylinder part. A rainwater take-out device in which a filter for filtering the rainwater is detachably installed and a rainwater take-out port for taking out the filtered rainwater extends from the bottom to the rainwater take-out tube portion from the connecting tube portion A water stop plate is installed to stand inward from the bottom on the connecting tube portion side of the filter of the rain water take-out tube portion, the water stop plate is removable, and in the state where the water stop plate is erected, rain water is taken out. Rainwater heading to the tube is stopped and the waterstop is removed In state it is passed through, characterized in that to allow water stop and passed through switching of the rainwater extraction tube portion.

  Second, in the first invention, the water stop plate has a locking piece for locking the filter of the rainwater take-out cylinder part at the upper end and the lower end, can be attached to the filter, and can be removed together with the filter. When the water stop plate is erected on the rain water take-out tube, attach the water stop plate to the filter, and then install the filter with the water stop plate in the rain water take-off tube, and remove the water stop plate In this case, the filter with the water stop plate is taken out from the rain water take-out tube portion, and then the water stop plate is removed from the filter.

  According to the first invention, the water stop plate that stops rainwater from the connecting cylinder part toward the rainwater extraction cylinder part is erected inward from the bottom on the connection cylinder part side of the filter of the rainwater extraction cylinder part. The rainwater heading toward the rainwater take-out tube portion is stopped, and as a result, the rainwater take-out can be stopped. Since the water stop plate is removable, it is possible to easily stop taking out rain water by attaching the water stop plate to the rain water take-out tube portion and standing up. Moreover, in the state which removed the water stop board, it can be made to let water flow to a rainwater extraction cylinder part. Therefore, by attaching or removing the water stop plate, it is easy to switch the water stop and water flow to the rainwater take-out tube.

  In addition, when the water stoppage is removed and there is a large amount of rainfall and a large amount of rainwater flows down from the upper side dredge, a part of it flows to the lower side dredge, so the rainwater extraction tube portion from the connecting tube portion As a result, the amount of rainwater taken out can be reduced.

  According to the second invention, the water stop plate has the locking pieces for locking the filter of the rainwater take-out cylindrical portion at the upper end and the lower end, can be attached to the filter, and can be removed together with the filter. When the water plate is erected on the rainwater take-out tube portion, the waterstop plate can be attached to the filter, and then the filter on which the waterstop plate is attached can be installed in the rainwater take-out tube portion. When removing the water stop plate, the filter equipped with the water stop plate can be taken out from the rain water take-out tube, and then the water stop plate can be removed from the filter. As described above, the attachment and detachment work of the water stop plate to the rainwater take-out tube portion can be performed by attaching and detaching the filter to the rainwater take-out tube portion, so that the work can be performed easily and efficiently.

  In addition, by installing a filter fitted with a water stop plate in the rain water take-out tube, the water stop plate is firmly fixed to the bottom of the rain water take-off tube, and rain water flowing from the connecting tube to the rain water take-out tube is collected. It can be stopped more reliably.

  FIG. 1 is a longitudinal sectional view showing an embodiment of a rainwater take-out device of the present invention, FIG. 2 is an exploded perspective view of the rainwater take-out device of FIG. 1, and FIG. 3 is an embodiment of a water stop plate. It is the perspective view which showed the form.

  The rainwater extraction device of the present embodiment includes a connecting cylinder portion 1 that connects the cylindrical upper rod 30 and the cylindrical lower rod 40, and a rainwater extraction that is connected to and integrated with the connecting cylinder portion 1. It has a cylindrical part 2 and constitutes a rainwater extraction part main body 3.

  The rainwater take-out body 3 has an opening 4 formed on the entire upper surface, and a detachable lid 5 is attached to cover the opening 4. A fitting cylinder portion 51 that is fitted inside the opening 4 of the rainwater extraction portion main body 3 is integrally suspended from the lower periphery of the lid 5. Moreover, the step part which consists of the outer peripheral surface of the lid | cover 5 and the fitting cylinder part 51 is formed, it latches by the upper edge part of the rainwater extraction part main body 3, and the lid | cover 5 is mounted | worn with the rainwater extraction part main body 3. . As described above, in the present embodiment, the fitting cylinder portion 51 of the lid 5 is fitted inside the opening 4 of the rainwater extraction portion main body 3 when the lid 5 is mounted. It is effective to improve the strength of the rainwater take-out body 3 as well as to prevent the entry of dust from the opening 4.

  The lid 5 is formed with an insertion port 52 through which the upper ridge 30 can be inserted, and the inner dimension thereof is substantially the same as or slightly smaller than the outer dimension of the upper ridge 30. The rainwater take-out body 3 is attached to the upper eave 30 with the lid 5 attached to the rainwater take-out body 3, and the lower end of the upper eave 30 is inserted into the connecting tube 1 from the insertion port 52 of the lid 5. The upper heel 30 and the rainwater take-out body 3 are connected to each other. In this embodiment, after attaching the rainwater extraction unit main body 3 to the upper heel 30, the lid 5 is attached and detached while the upper heel 30 is inserted into the insertion port 52 of the lid 5. When it is desired to remove the lid 5, the lid 5 is lifted upward, and when it is desired to attach the lid 5, the lid 5 is pushed down and attached. The upper ridge 30 functions as a guide portion that guides the lid 5 to the rainwater take-out portion main body 3, and the attachment of the lid 5 to the rainwater take-out portion main body 3 and the positioning for the attachment become easy. In addition, the lid 5 can be easily and reliably attached to and removed from the rainwater take-out portion main body 3, and the lid 5 is also prevented from being lost.

  In a state where the lid 5 is attached, a connecting portion 11 to which the lower rod 40 is connected is provided at the bottom of the connecting cylinder portion 1 of the rainwater extraction portion main body 3 below the insertion port 52 of the lid 5. 52 and substantially the same vertical position. The connecting part 11 has a cylindrical shape extending downward from the bottom plate 12 of the connecting cylinder part 1, and its outer dimension is substantially the same as or slightly smaller than the inner dimension of the lower flange 40. A collar 40 is fitted and attached to the connecting portion 11. Therefore, in the rainwater take-out device of the present embodiment, the upper kite 30 and the lower kite 40 are connected by the connecting cylinder part 1 on substantially the same vertical.

  A cylindrical middle cylinder 13 is erected inward from the bottom plate 12 on the upper side of the connecting part 11 of the connecting cylinder part 1, and the upper and lower flanges 30 and 40 are connected to the connecting cylinder part 1. In this state, the middle cylinder 13 is formed at a position so as to be coaxial with the upper side collar 30 and the lower side collar 40. The outer dimensions of the middle cylinder 13 are smaller than the inner dimensions of the upper flange 30 and the connecting portion 11. Further, the upper end and the lower end of the middle cylinder 13 are open, and the inside of the connecting cylinder part 1 is communicated with the connection part 11 through the middle cylinder 13.

  Inside the rainwater take-out body 3, the connecting tube portion 1 and the rainwater take-out tube portion 2 communicate with each other, and a rainwater take-out flow path 10 is formed. The rainwater take-out flow path 10 is a flow path that flows down from the upper ridge 30 along the inner wall surface thereof, and circulates rainwater received by the bottom plate 12 of the connecting tube portion 1 to the rainwater take-out tube portion 2. Garbage such as leaves and insects flows along the inner wall surface of the upper ridge 30 together with rainwater, and flows into the rainwater take-out tube portion 2. Here, the bottom plate 12 of the connecting cylinder portion 1 is configured as a pooled water bottom plate 8 that receives rainwater and dust flowing down from the upper ridge 30 and distributes them to the rainwater extraction cylinder portion 2.

  As described above, the rainwater flowing into the rainwater take-out device according to the present embodiment normally flows from the upper fly 30 along the inner wall surface thereof into the connecting cylinder portion 1 of the rainwater take-out portion main body 3. However, when the amount of rainfall is large, a flow of rainwater flowing away from the inner wall surface of the upper ridge 30 is formed in the upper ridge 30 along with the flow flowing down along the inner wall surface of the upper ridge 30. . In this case, rainwater that flows away from the inner wall surface of the upper rod 30 flows down from the connecting portion 11 to the lower rod 40 through the middle tube 13 of the connecting tube portion 1. As described above, the internal structure of the connecting cylinder portion 1 is designed to preferentially take out rainwater. However, when the amount of rainfall is large, a part of the rainwater flows to the lower ridge 40. Thus, all of the rainwater flowing down from the upper ridge 30 does not go from the connecting cylinder portion 1 to the rainwater extraction cylinder portion 2. Therefore, the flow rate of the rainwater heading from the connection cylinder part 1 to the rainwater extraction cylinder part 2 can be suppressed, and the amount of rainwater extraction can be suppressed. Note that the lower end of the upper ridge 30 is connected to the connecting cylinder portion so that rainwater and dust traveling on the inner wall surface of the upper ridge 30 can be reliably received by the bottom plate 12 of the connecting cylinder portion 1 and circulated to the rainwater extraction cylinder portion 2. The upper collar 30 may be connected to the connecting cylinder portion 1 so as to be lower than the upper end of the one intermediate cylinder 13.

  A cylindrical rainwater outlet port 9 extends downward from the bottom of the rainwater outlet cylinder 2 of the rainwater outlet main body 3 and communicates with the rainwater outlet cylinder 2. The rain water outlet 9 is fitted or inserted with an upper end of a member that forms a water passage such as a hose 20 connected to a rain water reservoir installed in a separate place. The rainwater circulated from 1 to the rainwater take-out tube portion 2 is taken out from the rainwater take-out port portion 9 to the rainwater storage tank through the hose 20 and the like.

  In the rainwater take-out device of the present embodiment, the filter 6 is filled in the rainwater take-out tube portion 2 and installed therein. The filter 6 is detachable so that it can be replaced or cleaned when it becomes dirty. As shown in FIGS. 1 and 2, the inner surface of the rainwater take-out tube portion 2 can be filled in the rainwater take-out tube portion 2. It has an outer shape corresponding to the shape. When the filter 6 is filled in the rainwater take-out tube portion 2, the filter 6 is inserted into the rainwater take-out tube portion 2 with the lid 5 removed from the rainwater take-out portion main body 3. By inserting the filter 6 into the rainwater take-out tube portion 2 and filling it, dust from the connecting tube portion 1 toward the rainwater take-out tube portion 2 is removed, and sand and dust contained in the rainwater are also removed by filtration. The The filtered rainwater is taken out from the rainwater outlet 9 below the filter 6.

  In the rainwater take-out device of the present embodiment, a removable water-resistant plate 7 made of synthetic resin or EPDM is disposed on the connecting tube portion 1 side of the filter 6 of the rainwater take-out tube portion 2. Stands inward from the bottom. The water stop plate 7 has a flat plate shape, the horizontal (width) dimension is substantially the same as the inner dimension of the rain water take-out tube portion 2, and is fitted and attached to the rain water take-out tube portion 2. 7 so that no gap is formed between both side end surfaces of the rainwater 7 and the inner wall surface of the rainwater extraction tube portion 2. The height of the water stop plate 7 needs to be high enough so that the rainwater flowing from the connecting tube portion 1 toward the rainwater extracting tube portion 2 does not exceed the water stop plate 7, and at least the height of the middle tube 13 of the connecting tube portion 1. It shall exceed the size. In order to stop the water more surely, the height dimension is set so that the upper end of the water stop plate 7 is positioned higher than the lower end of the upper flange 30. In the state where the water stop plate 7 is attached to the rainwater take-out tube portion 2, the rainwater take-out flow path 10 inside the rainwater take-out portion main body 3 is divided as a weir that stops rainwater from the connecting tube portion 1 toward the rainwater take-out tube portion 2. , Preventing rainwater from entering the rainwater take-out tube 2. Therefore, when it is desired to stop taking out rainwater from the rainwater take-out port portion 9, it can be easily realized by inserting the water stop plate 7 into the rainwater take-out tube portion 2.

  The actual water stop plate 7 is attached by removing the lid 5 from the rain water take-out body 3 and then inserting the water stop plate 7 into the rain water take-out tube 2 and then attaching the lid 5 to the rain water take-out body 3 again. Do as you do. When removing the water stop plate 7, the reverse operation is performed.

  In this way, the attaching and detaching work of the water stop plate 7 may be performed solely for the water stop plate 7 alone, but the water stop plate 7 is attached to the filter 6 from the viewpoint of ease of work and efficiency. The work may be performed in the state of being. In this embodiment, as shown in FIGS. 1 and 2, locking pieces 71 and 72 for locking the filter 6 are provided on the water stop plate 7. The locking pieces 71 and 72 are formed upright from the upper and lower ends of the water blocking plate 7 toward the filter 6 and have a flat plate shape. The water stop plate 7 can be attached to the filter 6 by inserting the filter 6 between the lock pieces 71 and 72 of the water stop plate 7 and sandwiching the filter 6 with the lock pieces 71 and 72. When the water stop plate 7 that can be attached to the filter 6 in this way is attached to the rainwater take-out tube portion 2, the lid 5 is removed from the rainwater take-out portion main body 3, and the filter 6 is taken out from the rainwater take-out tube portion 2. A water stop plate 7 is attached. Next, after the filter 6 with the water stop plate 7 attached is inserted into the rainwater take-out cylinder portion 2 and installed inside, the lid 5 is attached to the rainwater takeout portion main body 3 again. When removing the water stop plate 7, the reverse operation is performed. That is, the lid 5 is removed from the rainwater take-out body 3, the filter 6 with the water stop plate 7 attached is taken out from the rainwater take-out tube portion 2, and the water stop plate 7 is removed from the filter 6. Next, after the filter 6 is inserted into the rainwater take-out tube portion 2 and installed therein, the lid 5 is attached to the rainwater take-out portion main body 3 again.

  By installing the filter 6 fitted with the water stop plate 7 in the rain water take-out tube portion 2 in this way, the water stop plate 7 is firmly and firmly fixed to the bottom in the rain water take-out tube portion 2. The presence of the locking pieces 71 and 72 of the water stop plate 7 has an advantage that rainwater from the connecting cylinder portion 1 toward the rainwater extraction cylinder portion 2 can be more reliably stopped. In order to make the advantages such as fixing of the water stop plate 7 and preventing rainwater intrusion even more remarkable, the water stop plate 7 having a form as shown in FIG. 3 can be provided. In the water stop plate 7, the outer shape of the locking piece 72 at the lower end corresponds to the shape of the inner peripheral surface of the rainwater extraction tube portion 2. Since the water stop plate 7 having such a locking piece 72 has a large contact area with the bottom in the rainwater extraction tube portion 2, it can be stably fixed. In addition, since the rainwater outlet 9 is closed, the intrusion of rainwater from the connecting tube portion 1 and the stoppage of rainwater from the rainwater outlet 9 can be further ensured. Further, the attachment with the filter 6 becomes easier, and the attachment and detachment work to and from the rainwater take-out tube portion 2 in the state where the water stop plate 7 is attached to the filter 6 become easier.
