[0012] According to the present invention, it is possible to provide a clogging removal device that can more effectively remove clogging from a strainer. [Brief explanation of the drawing]
[0013] [Figure 1] This is an explanatory diagram illustrating the configuration of a strainer clogging removal device according to one embodiment of the present invention. [Figure 2] Figure 1 shows a view from above of the section of the drainage channel where the strainer is installed. [Figure 3] Figure 1 is an enlarged cross-sectional view of the main part of the strainer clogging removal device. [Figure 4] Figure 1 is an explanatory diagram showing how the strainer clogging removal device removes blockages from the strainer. [Modes for carrying out the invention]
[0014] The configuration of a strainer clogging removal device 1 according to one embodiment of the present invention will be described in detail below with reference to the drawings.
[0015] In Figures 1 and 2, reference numeral 10 denotes a drain channel equipped with a strainer clogging removal device 1 according to one embodiment of the present invention. In this embodiment, the drain channel 10 has a substantially U-shaped cross-section with a pair of side walls 11 and a bottom wall 12, and is a rain gutter arranged along the lower edge of the roof of a building such as a house, so that water is collected inside it. In Figures 1 and 2, only a part of the drain channel 10 is shown, and in reality, the drain channel 10 extends to the left and right with a length corresponding to the width of the roof.
[0016] The water collection channel 10 is provided with an outlet 13. The outlet 13 is positioned to allow water collected in the water collection channel 10 and flowing along the water collection channel 10 to be discharged to the outside. As shown in Figure 1, in this embodiment, the bottom wall 12 is inclined with respect to the horizontal direction, and the circular outlet 13 is provided at the lowest part of the bottom wall 12 in a plan view.
[0017] Furthermore, the water collection channel 10 is not limited to a substantially U-shaped cross-section having a pair of side walls 11 and a bottom wall 12. It may have various configurations as long as it can collect water and guide it to the outlet 13. For example, a configuration in which the bottom wall 12 is horizontally arranged without an incline, or a configuration in which it extends only to one side (left or right) relative to the outlet 13.
[0018] Furthermore, the water collection channel 10 is not limited to a configuration in which the discharge port 13 is provided on the bottom wall 12 of the water collection channel 10, but can also be configured in which the discharge port 13 is provided at another location from which the collected water can be discharged.
[0019] Furthermore, the water collection channel 10 is not limited to a rain gutter provided in a building, and may be various water collection channels such as a water collection gutter provided on the roof of a building such as a building, or a side gutter provided on the side of a road.
[0020] As shown in FIG. 1, a discharge pipe 20 is connected to the discharge port 13. The discharge pipe 20 extends downward from the discharge port 13, and its inner side forms a vertical discharge path 21. That is, the discharge port 13 is the opening of the vertical discharge path 21 connected to the water collection channel 10. The lower end of the discharge pipe 20 is open to the outside of the water collection channel 10. Therefore, the water such as rainwater that is collected in the water collection channel 10 and guided to the discharge port 13 through the water collection channel 10 flows into the vertical discharge path 21 inside the discharge pipe 20 from the discharge port 13, and is discharged to the outside of the water collection channel 10 through the vertical discharge path 21.
[0021] A strainer 30 is attached to the discharge port 13. The strainer 30 is a net-like device for removing relatively large foreign objects such as fallen leaves from water such as rainwater. In the present embodiment, the strainer 30 is formed by combining a plurality of wires in a lattice shape, and the outer peripheral edge 31 at the lower end is circular in accordance with the shape of the discharge pipe 20 and has a dome shape that is curved upward in a hemispherical shape. By attaching the strainer 30 to the discharge port 13, it is possible to prevent relatively large foreign objects such as fallen leaves from entering the vertical discharge path 21 from the discharge port 13 and causing clogging.
[0022] A clogging removal device 1 for a strainer according to an embodiment of the present invention (hereinafter, may be simply referred to as "clogging removal device 1") removes clogging of the strainer 30 attached to the discharge port 13 of the water collection channel 10.
[0023] The clogging removal device 1 has a fluid ejection part 40 arranged around the strainer 30 and a fluid supply part 41 that supplies fluid to the fluid ejection part 40. The clogging removal device 1 is configured such that when fluid is supplied from the fluid supply part 41 to the fluid ejection part 40, fluid is ejected from the fluid ejection part 40 around the strainer 30.
[0024] The fluid supplied by the fluid supply unit 41 to the fluid ejection unit 40 can be air, recycled rainwater, or other fluids. In this embodiment, air is used as the fluid. By using air as the fluid, the configuration of the fluid supply unit 41 can be simplified, and the cost of the clogging removal device 1 can be reduced. The following description will focus on the case where air is used as the fluid, but similar effects can be obtained when other fluids such as water are used.
[0025] In this embodiment, the fluid ejection section 40 is composed of an annular pipe material 42 extending along the outer peripheral edge 31 of the strainer 30. The pipe material 42 can be made of metal such as steel or aluminum alloy, or of synthetic resin. In this embodiment, since the outlet 13 is circular, the pipe material 42 constituting the fluid ejection section 40 is an annular shape extending along the outer peripheral edge 31 of the strainer 30.
[0026] The pipe material 42 is provided with a plurality of discharge holes 40a arranged along the outer peripheral edge 31 of the strainer 30. In Figure 2, for convenience, only one discharge hole 40a is labeled. The plurality of discharge holes 40a each open upward and are arranged at equal intervals in the circumferential direction.
[0027] The number, orientation, and arrangement of the multiple discharge holes 40a provided in the pipe material 42 can be changed in various ways, for example, by arranging the multiple discharge holes 40a to blow air along the grid of the strainer 30, as long as air can be blown out from the multiple discharge holes 40a to desired positions around the strainer 30.
[0028] The fluid supply unit 41 can be configured, for example, by a pump that pressurizes and pumps air (fluid) toward the fluid outlet unit 40. The fluid supply unit 41 can be placed at any location, such as on the exterior wall of a building or inside a building, and connected to the fluid outlet unit 40 or pipe material 42 by piping 43. In this embodiment, one end of the piping 43 is connected to the radially inner portion of the pipe material 42, penetrates the bottom wall 12 of the water collection channel 10, is arranged along the discharge pipe 20, and is connected to the fluid supply unit 41 at the other end.
[0029] When the fluid supply unit 41 starts operating, as shown in Figure 3, air is supplied from the fluid supply unit 41 through the piping 43 to the fluid ejection unit 40 or pipe material 42. The air supplied to the fluid ejection unit 40 or pipe material 42 passes through the inside of the pipe material 42 and is ejected upward from each discharge hole 40a towards the area around the strainer 30. The pressure of the air supplied from the fluid supply unit 41 to the fluid ejection unit 40 or pipe material 42 is set to any pressure that can prevent clogging of the strainer 30 by blowing away accumulated sediment such as soil around the strainer 30 with the air ejected from the discharge holes 40a.
[0030] The fluid supply unit 41 can be configured to start operating when activated by an operator, but it may also be configured to operate for a predetermined time at predetermined intervals set by a timer, or it may be configured to operate for a predetermined time when clogging of the strainer 30 is detected by a sensor.
[0031] As shown in Figure 4, in a water collection channel 10 with a strainer 30 attached to the discharge port 13, sediment 50 consisting mainly of soil and fallen leaves (mainly soil) accumulates around the strainer 30. This sediment 50 can clog the strainer 30, causing poor drainage and potentially leading to problems such as excessive water 60 accumulating in the water collection channel 10 and causing leaks. The clogging removal device 1 of this embodiment can remove such clogging of the strainer 30 caused by sediment 50.
[0032] In other words, when sediment 50 such as soil and fallen leaves accumulates around the strainer 30, the fluid ejection section 40 positioned around the strainer 30 becomes embedded in the sediment 50. The clogging removal device 1 operates the fluid supply section 41 in this state and supplies air from the fluid supply section 41 to the fluid ejection section 40, thereby sending air from below into the sediment 50 through the discharge hole 40a of the fluid ejection section 40, causing the sediment 50 (the part of the sediment 50 mainly composed of soil) to be in a state similar to a boiling phenomenon. mosquito It can be disturbed. The sediment 50 is supplied with air as described above. mosquito As the sediment is disturbed, it becomes easier for the water 60 accumulated in the drainage channel 10 to flow through the strainer 30 towards the outlet 13, thereby allowing the sediment 50 to flow towards the outlet 13 and removing any blockage in the strainer 30 caused by the sediment 50.
[0033] As described above, the clogging removal device 1 according to this embodiment has a fluid ejection section 40 arranged around the strainer 30 and a fluid supply section 41 that supplies air to the fluid ejection section 40, thereby removing the accumulated deposits 50 around the strainer 30 by the air ejected from the fluid ejection section 40. mosquito By disturbing the sediment 50, it becomes easier for the sediment 50 to flow through the strainer 30 toward the outlet 13 along with the water 60 accumulated in the drainage channel 10, thereby more effectively removing clogging of the strainer 30 by the sediment 50 than in conventional methods.
[0034] Furthermore, in the case of the clog removal device 1 according to this embodiment, when the strainer 30 is clogged with sediment 50 but there is no water accumulated in the water collection channel 10, the fluid supply unit 41 is activated in this state, and air is supplied from the fluid supply unit 41 to the fluid ejection unit 40, thereby effectively removing the clog of the strainer 30 by blowing away the sediment such as soil accumulated around the strainer 30 with air.
[0035] Furthermore, in the clogging removal device 1 according to this embodiment, the fluid ejection section 40 is made of a pipe material 42 that is annular in shape extending along the outer peripheral edge 31 of the strainer 30 and has a plurality of discharge holes 40a arranged in a direction along the outer peripheral edge 31 of the strainer 30. As a result, air is efficiently supplied to the deposits 50 around the entire circumference of the outer peripheral edge 31 of the strainer 30, thereby more effectively removing clogging of the strainer 30 caused by the deposits 50.
[0036] Furthermore, in the clogging removal device 1 according to this embodiment, the discharge port 13 is the opening of the vertical discharge channel 21 connected to the water collection channel 10. This allows the sediment 50 supplied with air at the outer peripheral edge 31 of the strainer 30 to flow more easily from the discharge port 13 through the vertical discharge channel 21 to the outside, thereby more effectively removing clogging of the strainer 30 caused by the sediment 50.
[0037] In this case, if the drainage channel 10 is a rain gutter installed on a building, the outlet 13 or strainer 30 will be positioned along the lower edge of the roof, making it difficult for a worker to directly remove the accumulated sediment 50 around the strainer 30 by hand. In contrast, with the clogging removal device 1 according to this embodiment, the worker can operate the fluid supply unit 41 in a location accessible to the worker, thereby activating the fluid supply unit 41 and removing the clogging of the strainer 30 caused by the accumulated sediment 50, as described above. This makes the work of removing the clogging of the strainer 30 much easier.
[0038] The present invention is not limited to the embodiments described above, and various modifications are possible without departing from the spirit of the invention.
[0039] For example, the fluid ejection section 40 can be configured using pipe material 42 of various shapes that can be arranged around the strainer 30, such as a C-shape with a joint.
[0040] Furthermore, the fluid ejection section 40 can be made of a material other than the pipe material 42, such as a flexible synthetic rubber or synthetic resin tube with a discharge hole 40a, as long as it is arranged around the strainer 30 and can eject air (fluid) around the strainer 30.
[0041] Furthermore, the fluid ejection section 40 may be shaped to be positioned only on a portion of the entire circumference of the strainer 30, such as being positioned only on the portion of the strainer 30 facing the direction of extension of the water collection channel 10.
[0042] Furthermore, the strainer 30 to which the discharge port 13 is attached is not limited to a circular shape in plan view, but can be of various shapes, such as a rectangular shape in plan view. In this case, it is preferable that the shape of the fluid ejection section 40 or pipe material 42 be made to match the shape of the strainer 30.
[0043] Furthermore, the strainer 30 is not limited to a dome shape in which multiple wires are arranged in a grid pattern. Any strainer that can remove relatively large foreign objects such as fallen leaves from rainwater or other water can be used, such as one made of perforated metal, or any other structure or shape.
