Description

[Technical field]

[0001] The present invention relates to a siphon water conveying device and a siphon water conveying method using the same. [Background technology]

[0002] The siphon water supply device is a water supply device that supplies water from a water storage section in a high water area to a low water area by siphon action. As shown in Fig. 6, as one of the essential components indispensable to the conventional siphon water supply device 200, a water inlet opening and closing device or a water inlet check valve 210 was required at the upstream end of the siphon water supply hose 10 immersed in the upstream water storage section 1. The water inlet opening and closing device or the water inlet check valve 210 was provided and closed, and an opening and closing device 230 was also provided at the discharge port 220 at the most downstream end of the siphon water supply hose 10. In this state, water was poured from the water inlet 240 provided at the highest part of the piping, and the entire length of the siphon water supply hose 10 on the upstream and downstream sides of the water inlet 240 was filled with water. This was because it was common knowledge that the siphon action could not be started unless the entire length of the siphon water supply hose 10 was filled with water. Therefore, in the past, the entire length of such a siphon water supply hose was filled with water, and then the open / close type water inlet member 240 at the highest part of the piping was closed, and then the upstream water inlet opening / closing device or water inlet check valve 210 and the downstream opening / closing device 230 were opened to activate the siphon action.

[0003] In this way, in the conventional siphon device, water was poured from the openable water inlet member installed at the highest part of the piping while both the upstream water inlet opening and closing device or the water inlet check valve and the downstream discharge opening and closing device were closed, and when the entire extension of the siphon water supply hose was filled with water, the opening of the openable water inlet member had to be closed and both the upstream water inlet opening and closing device or the water inlet check valve and the downstream discharge opening and closing device had to be opened. However, this work involved danger for people to approach because the upstream water inlet opening and closing device was under the water of the reservoir. Also, opening the downstream discharge opening and closing device involved dangerous work, as it required going up and down the dangerous embankment slope.

[0004] After the siphon water supply work is completed, the work of removal begins. At this time, the upstream siphon water supply hose is manually pulled up from the top of the embankment, but because the upstream water intake opening and closing device is underwater, the diameter of the water intake opening and closing device is generally larger than the siphon water supply hose and has a handle for opening and closing it, so there is a possibility that it will get caught on obstacles on the bottom of the lake or that aquatic plants will get tangled in the handle and make it difficult to pull it up.

[0005] On the other hand, since the work process of closing the intake opening and closing device in the water on the upstream side is dangerous, an intake check valve may be used instead of the intake opening and closing device. In the case of an intake check valve, when water is poured into the siphon water supply hose, the poured water remains in the siphon water supply hose due to the check valve, so when the siphon water supply hose is filled with water, the downstream discharge opening and closing device is opened after closing the opening of the openable water pouring member, and the upstream intake check valve is pushed open by the water sucked in by the water suction phenomenon and flows in, so the work of manually opening the check valve can be omitted. However, when the siphon water supply work is completed and removal work is started, when the upstream siphon water supply hose is pulled up, the check valve is closed, so the water in the siphon water supply hose cannot be discharged from the intake to the water storage section outside, so there is a problem that the heavy hose with water in the hose still full of water must be pulled up by many workers or a crane, etc. Summary of the Invention [Problem to be solved by the invention]

[0006] Therefore, the present invention has been made in consideration of the above-mentioned problems, and aims to provide a siphon device and a siphon water supply method in which the installation work of the siphon water supply device and the siphon start-up work are simpler than those of conventional siphon water supply devices, and the removal work after the siphon water supply work is completed can also be carried out easily and quickly. [Means for solving the problem]

[0007] In order to solve the above problems, the siphon water supply device according to the present invention is structured such that the intake opening / closing device or intake check valve provided at the most upstream part of the siphon water supply hose and the outlet opening / closing device at the most downstream part are omitted, and the upstream water inlet opening / closing member or the upstream water inlet check valve member is provided at a position between the water surface of the water storage part on the upstream side of the single-pipe and the open / close type water inlet member provided near the highest part of the siphon water supply hose. This is because the upstream water inlet opening / closing member can be operated on land by being located upstream of the open / close type water inlet member and above the water surface of the water storage part. The configuration of the siphon water supply device will be described as a single-pipe configuration, but the invention of the siphon water supply device also includes the use of this configuration in multiple pipes.

[0008] In addition, water can be poured by connecting a water injection hose connection part of a diameter equal to or larger than the siphon water supply hose connected to a water supply device of the same diameter or larger, or a connection part of a flow collecting member having a function of merging the flows of a plurality of water injection hoses connected to a water supply device of the same diameter or smaller than the siphon water supply hose to the openable water inlet member. After the water injection is completed, the opening of the openable water inlet member is closed, and the water injection hose can be removed after the siphon is started. The openable water inlet member also serves the function of sucking in air when the siphon action is stopped. The water inlet upstream opening and closing member can also be used to temporarily suspend the siphon flow in the siphon water supply hose during siphon action.

[0009] According to the siphon water supply device of the present invention, it is possible to eliminate the need for dangerous work in water to open and close the opening of the water inlet opening and closing device at the most upstream position, which was previously required, and the need to go up and down a slope to open and close the opening and closing device at the most downstream position. Also, since the water inlet upstream opening and closing member or the water inlet upstream check valve member is provided at the upstream portion of the open-close type water inlet member, when a water supply device and a water inlet hose having the same or larger diameter as the siphon water supply hose are used to connect to the open-close type water inlet member to inject water into the siphon water supply hose, the water moves separately to the upstream and downstream sides, but since the upstream side is blocked by the water inlet upstream opening and closing member or the water inlet upstream check valve member, the water cannot proceed any further upstream and remains in the siphon water supply hose. When the siphon water supply hose from the water inlet upstream opening and closing member or the water inlet upstream check valve member to the discharge port at the downstream end of the siphon water supply hose becomes full of water due to water injection and starts to flow, if the water inlet upstream opening and closing member is opened while continuing the water injection operation, the water in the siphon water supply hose between the open-close type water inlet member and the discharge port at the downstream end is pulled by potential energy toward the discharge port at the downstream end, and when the air and water in the upstream siphon water supply hose from the water inlet upstream opening and closing member starts to flow downstream, the water injection operation is stopped and the siphon water supply operation is started. In the case of the water inlet upstream check valve member, the air in the siphon water supply hose upstream of the water inlet upstream check valve member is sucked into the water injection flow, and the water level in the siphon water supply hose gradually rises by that amount, and when the water reaches the water inlet upstream check valve member, it pushes the check valve from the upstream side and moves to the downstream side of the water inlet upstream check valve member. The air in the siphon water supply hose between the water inlet upstream opening and closing member or the water inlet upstream check valve member and the water surface in the upstream water storage section is also drawn downstream and flows down. As this flows down, the water in the water storage section is sucked in from the intake port behind the air and flows down inside the siphon water supply hose. When this air is discharged from the discharge port, the siphon water supply hose continues to flow down when filled with water, and the siphon action is activated.

[0010] In addition, the present invention allows water to be injected by connecting the flow of a water collection and merging member, which has the function of merging the flows of multiple water injection hoses connected to multiple water supply devices of the same diameter or smaller as the siphon water supply hose, to an open-close water inlet member via a water injection hose, and supplying a water volume equal to or greater than that of a water supply device of the same diameter as the siphon water supply hose.

[0011] The present invention also employs a configuration in which a flexible hose-in damming member in the form of a sponge-like or balloon-like mass is inserted into the siphon water supply hose immediately downstream of the open-close type water inlet member. A configuration is adopted in which a small-diameter water inlet hose with a diameter less than that of the siphon water supply hose is connected to a small-diameter water supply device with a diameter less than that of the siphon water supply hose, and water is injected into the siphon water supply hose by connecting the small-diameter water inlet member to the open-close type water inlet member. Alternatively, after water injection is completed, the opening of the open-close type water inlet member is closed to start the siphon, and the water inlet hose can be removed.

[0012] According to this invention, dangerous work in water for opening and closing the opening of the intake opening opening device at the most upstream part, as described above, and opening and closing work of the opening and closing device installed at the most downstream part, which is performed by going up and down a slope, can be omitted. In addition, the connecting part of the water collection and merging member having a function of merging the flows of a plurality of water injection hoses connected to a water supply device having a diameter smaller than the siphon water supply hose, which is of course equal to or larger than the siphon water supply hose, or a plurality of water supply devices having a diameter smaller than the siphon water supply hose, and supplying a water amount equal to or larger than that of a water supply device having the same diameter as the siphon water supply hose, can be connected to the open-close type water inlet member via the water injection hose to inject water into the siphon water supply hose. Since the water inlet upstream opening and closing member or the water inlet upstream check valve member is closed at the upstream part of the open-close type water inlet member, the water cannot proceed upstream and remains in the siphon water supply hose. When the water injected by the water pressure of the water supply device accumulates, water pressure is applied to the flexible hose inner damming member, which is a sponge-like or balloon-like mass inserted into the siphon water supply hose before the water injection operation, and the hose inner damming member is gradually pushed downstream by the water pressure of the water supply device and moves. When the hose inner damming member eventually reaches the downstream discharge port, the siphon water supply hose is filled with water from the upstream opening and closing member of the siphon water supply hose or the upstream check valve member of the water supply port to the discharge port at the downstream end of the siphon water supply hose, and the hose inner damming member is pushed out from the discharge port. Once it is confirmed that it has been pushed out, the upstream opening and closing member of the water supply port is opened. As a result, the water in the siphon water supply hose between the openable water supply port member and the discharge port at the downstream end starts to flow all at once in the direction of the discharge port at the downstream end due to potential energy. In the case of the check valve member upstream of the water inlet, the check valve opens in the downstream direction because the water flow changes to a downstream direction. The water in the siphon water supply hose between the open-close type water inlet member installed near the highest part of the siphon water supply hose and the discharge port at the downstream end starts to flow all at once in the direction of the discharge port at the downstream end due to potential energy.The potential energy causes the water in the siphon water supply hose to flow down all at once toward the discharge port at the downstream end, drawing in the air in the hose between the water inlet upstream opening and closing member or the water inlet upstream check valve member and the water surface in the upstream water storage section into the downstream section as it flows down. As the air flows down, the water in the water storage section is also sucked in from the suction port and flows down inside the siphon water supply hose. When the air is expelled from the discharge port, the siphon water supply hose continues to flow down when it is full of water, and the siphon action is activated.

[0013] Furthermore, the present invention provides a discharge flow rate adjusting device capable of adjusting the flow rate of water discharged to the downstream end of a siphon water supply hose. of By adopting such a configuration, it is possible to inject water using a water supply device while the opening of the open-close type water inlet member is left open without connecting a water inlet hose, or to manually inject water into the opening of the open-close type water inlet member using a container such as a bucket.

[0014] If a discharge flow rate regulator is provided at the downstream end of the siphon hose, the amount of water sent after the siphon is activated can be adjusted. At the same time, when water is sent from a small-diameter water inlet hose connected to a small-diameter water supply device with a diameter smaller than that of the siphon water supply hose, or when water is sent manually through an openable water inlet member using a container such as a bucket, the siphon outlet can be closed with the discharge flow rate regulator without using a damming member inside the hose, and water is stored in the siphon outlet from the downstream end in order by the water inlet, and when the siphon water supply hose is filled up to its highest point, the discharge flow rate regulator and the upstream openable water inlet member are opened. As a result, the water in the siphon water supply hose between the openable water inlet member and the outlet at the downstream end starts to flow all at once in the direction of the outlet at the downstream end due to potential energy. In the case of a check valve member upstream of the water inlet, the water in the siphon water supply hose starts to flow downstream from the top of the pipe due to potential energy. This movement sucks up air between the check valve member upstream of the water inlet and the water surface in the upstream water storage section and moves it downstream. The moving air then draws new water from the water storage section into the siphon water supply hose through the water intake, activating the siphon action. [Brief description of the drawings]

[Figure 6] FIG. 6 is a side view showing the outline of the configuration of a conventional siphon water supply device 100. As shown in FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] (First embodiment) Next, the siphon water conveying device 100 according to the first embodiment will be described in detail with reference to the drawings. The siphon water conveying device 100 according to the first embodiment is shown in FIG.

[0017] As shown in FIG. 1, the siphon water supply device 100 of the first embodiment mainly comprises a single-piped siphon water supply hose 10 having a water intake port 11 that absorbs water from a water storage section 1 in an upstream area or high water area and a discharge port 12 that discharges water in a low water area, an open-close type water inlet member 20 having a water inlet 21 for injecting water, a water inlet upstream opening-closing member or a water inlet upstream check valve member 30 that is provided upstream of the open-close type water inlet member 20, a water inlet hose 40 connected to the water inlet 21 that is equipped with a water inlet opening-closing lever 21A, and a water supply device 50 such as a submersible pump that injects water into the siphon water supply hose 10 to start the siphon water supply device 100.

[0018] The siphon water supply hose 10 used in the siphon water supply operation is made of a hard hose or pipe material whose cross-sectional shape does not easily deform. Examples of hoses made of hard materials include suction hoses, hoses made of hard polyethylene or polyvinyl chloride, and steel pipes. The siphon water supply hose 10 has a water intake port 11 at the upstream end, and is disposed in a water storage section 1 such as a pool, pond, swamp, river, or dam, which is an upstream area or high water area. On the other hand, the downstream side has a discharge port 12 for discharging water, and the discharge port 12 is disposed in a low water area that is at least lower than the water level of the water storage section 1 such as a pool, pond, swamp, river, or dam, which is a high water area.

[0019] The open / close type water inlet member 20 is placed at or near the highest point, which is the highest position of the piped siphon water supply hose 10. The open / close type water inlet member 20 has an openable water inlet 21 for injecting water into the siphon water supply hose 10, and a water inlet opening / closing lever 21A for opening and closing the opening of the water inlet 21. The water inlet 21 has a flange at its opening, to which a connection part 41 of a water inlet hose 40 can be attached.

[0020] The installation condition is that the piping extension of the siphon water supply hose 10 downstream of the open-close type water inlet member 20 is piped to a height (head difference) lower than the water level in the upstream water storage section 1, and the larger the head difference is, the greater the amount of water supplied. When the siphon water supply hose 10 downstream of the open-close type water inlet member 20 is full of water and begins to flow down, the air within the siphon water supply hose 10 from the open-close type water inlet member 20 to the water level in the upstream water storage section 1 is drawn in and begins to flow down. When this air reaches the discharge port 12 at the downstream end of the siphon water supply hose 10, the newly drawn water from the water storage section follows behind the air, so it is discharged in the same way, starting the siphon action. Therefore, the same effect can be achieved if the water inlet upstream opening / closing member 30A (30) or the water inlet upstream check valve member 30B (30) is installed upstream of the open / close type water inlet member 20 and between the water surface of the water storage section 1, but it is more convenient to install it near the open / close type water inlet member 20 because the operator can operate it on the spot without having to move. The water inlet upstream opening / closing member 30A is a member having an opening / closing part that can manually open and close the inside of the siphon water supply hose 10, and the water inlet upstream check valve member 30B has an internal check valve 31B as shown in a circle in Figure 1, which allows water to flow from the water inlet 11 side to the discharge port 12 side and prevents water from flowing from the discharge port 12 side to the water inlet 11 side.

[0021] The water injection hose 40 is a hose that is attached to the water injection port 21 of the open-close type water injection port member 20, and in addition to a hard hose or pipe material, a soft hose can also be used.

[0022] The water conveying device 50 is a pump with a water conveying function that is operated by electricity, and injects water into the water inlet 21 of the open-close water inlet member 20 via a water inlet hose 40. The water conveying device 50 can be turned on and off by a switch (not shown) on a distribution board that draws in the power from a generator or a system.

[0023] The siphon water supply device 100 according to the first embodiment configured as described above is used when the water supply device 50 has the same diameter as the siphon water supply hose 10 or more, and is connected to the open-close type water inlet member 20 to inject water into the siphon water supply hose 10, and when the siphon water supply hose 10 can be kept full of water. In this siphon water supply device 100, the water inlet upstream opening and closing member or the water inlet upstream check valve member 30 is installed upstream of the open-close type water inlet member 20. Therefore, when the water supply device 50 injects water from the water inlet 21 of the open-close type water inlet member 20, the water flows both upstream and downstream. However, since the upstream side is blocked by the water inlet upstream opening and closing member or the water inlet upstream check valve member 30, the water does not proceed upstream and remains in the siphon water supply hose 10. If the water supply device 50 continues to supply water thereafter, the inside of the siphon water supply hose 10 from the upstream water inlet opening / closing member or upstream water inlet check valve member 30 to the discharge port 12 at the downstream end of the siphon water supply hose 10 will be filled with water and will begin to flow. If this state is confirmed, in the case of the upstream water inlet opening / closing member 30A, if the opening / closing part is opened while maintaining this state, the water in the siphon water supply hose 10 between the open / close type water inlet member 20 and the downstream end discharge port 12 will continue to flow in the direction of the downstream end discharge port 12 due to potential energy together with the water injection action. The air in the siphon water supply hose 10 between the upstream water inlet opening / closing member 30A and the water surface of the upstream water storage section 1 will also be drawn into the downstream section and flow down. Then, as this flow down, the water in the water storage section 1 will also be sucked in from the water intake port 11 behind the air and flow down inside the siphon water supply hose 10. When this air is discharged from the discharge port 12, the siphon water supply hose 10 continues to flow down when filled with water, activating the siphon action. On the other hand, in the case of the water inlet upstream check valve member 30B, the air inside the siphon water supply hose 10 on the upstream side of the water inlet upstream check valve member 30B is sucked into the flow of poured water during the water inlet operation, causing the water level to rise gradually by that amount. When the water reaches the water inlet upstream check valve member 30B, it pushes the check valve from the upstream side, and the water moves further downstream of the water inlet upstream check valve member 30B.Then, just like the water inlet upstream opening and closing member 30A, the water in the siphon water supply hose 10 between the water inlet upstream opening and closing member or the water inlet upstream check valve member 30 and the water surface in the upstream water storage section 1 continues to be drawn downstream and flow down. As this flow goes down, water in the water storage section 1 is also sucked in through the water intake port 11 and flows down inside the siphon water supply hose 10. When this water is discharged from the discharge port, the siphon water supply hose 10 continues to flow down in a full water state, and the siphon action is started.

[0024] According to the siphon water supply device 100 of the present invention, the dangerous underwater work required to open and close the opening and closing device is eliminated by eliminating the water intake opening opening and closing device that was previously installed at the most upstream part, and the opening and closing device installed at the most downstream discharge port 12 of the siphon water supply hose 10 is eliminated, making it possible to omit the work of opening and closing the opening and closing device installed at the most downstream discharge port 12, which requires going up and down a slope.

[0025] Second embodiment The siphon water supplying device 110 according to the second embodiment will be described in detail with reference to the drawings. The siphon water supplying device 110 according to the second embodiment is shown in FIG.

[0026] Of the configurations of the siphon water supply device 110 in the second embodiment, the configurations of the siphon water supply hose 10, the open / close type water inlet member 20, the water inlet upstream opening / closing member or the water inlet upstream check valve member 30, the water inlet hose 40 connected to the water inlet 21, the water inlet opening / closing lever 21A, and the water supply equipment 50 are the same as those in the first embodiment, so description thereof will be omitted.

[0027] The siphon water supply device 110 of the second embodiment is different from the siphon water supply device 100 of the first embodiment in that a flexible hose damming member 60 in the form of a sponge-like or balloon-like mass is inserted into the siphon water supply hose 10 immediately downstream of the open-close type water inlet member 20 (within 1 m from the open-close type water inlet member 20).

[0028] By adopting such an internal hose blocking member 60, a small-diameter water injection hose 40A having a diameter less than that of the siphon water supply hose 10, which is connected to a small-diameter water supply device 50 having a diameter less than that of the siphon water supply hose 10, is connected to the open-close type water inlet member 20 and water is injected into the siphon water supply hose 10. Even with a small amount of water being injected, the internal hose blocking member 60 is gradually pushed downstream by the water pressure of the water supply device 50, and when it eventually reaches the discharge port 12, the inside of the siphon water supply hose 10 up to the water inlet upstream opening and closing member or the water inlet upstream check valve member 30 upstream of the internal hose blocking member 60 is in a full water state, and when the internal hose blocking member 60 is pushed out of the discharge port 12, the action of drawing in water from the upstream siphon water supply hose 10 in the upstream part from the water inlet upstream opening and closing member or the water inlet upstream check valve member 30 is activated, and at the same time, the action of sucking in new water from the reservoir 1 from the water inlet upstream opening and closing member or the water inlet upstream check valve member 30 is activated. When this newly drawn water reaches the discharge port 12, the siphon action is initiated.

[0029] 3, when the flows of a plurality of small-diameter water injection hoses 40A connected to a plurality of small-diameter water supply devices 50A having a diameter equal to or smaller than the siphon water supply hose 10 are joined together at a water collection and merging member 42 and passed through the connected water injection hose 40, and water is injected into the siphon water supply hose 10 through the connected openable and closable water inlet member 20, even if the water supply device 50 having the same diameter as the siphon water supply hose 10 requires a 200V power source, the 100V small-diameter water supply device 50A can be operated using a small generator, and the siphon action can be started with the joined flow. Even if the water supply amount of the small-diameter water supply device 50A is not enough to start the siphon, the siphon action can be started in the same manner as described above by using the hose inner blockage member 60.

[0030] In the siphon water supply device 110 according to the second embodiment, when water is injected from the water inlet 21, the water inlet upstream open / close member or water inlet upstream check valve member 30 is closed at the upstream part of the open / close type water inlet member 20, so the water cannot proceed upstream and remains in the siphon water supply hose 10. When water is injected by the water supply equipment 50, water pressure is applied to the retained water, and the water pressure is applied to the flexible in-hose damming member 60, which is a sponge-like or balloon-like mass inserted in the siphon water supply hose 10, and the water pressure of the water supply equipment 50 gradually pushes and moves the in-hose damming member 60 downstream. When the hose internal blocking member 60 eventually reaches the downstream discharge port 12, the inside of the siphon water supply hose 10 between the water inlet upstream opening and closing member or the water inlet upstream check valve member 30 of the siphon water supply hose 10 and the discharge port 12 at the downstream end of the siphon water supply hose 10 is filled with water due to the injection of water. Then, the hose internal blocking member 60 is pushed out from the discharge port 12 at the downstream end of the siphon water supply hose 10. Once it is confirmed that it has been pushed out, the opening and closing part is opened in the case of the water inlet upstream opening and closing member 30A while continuing the water injection operation. As a result, the water in the siphon water supply hose 10 between the openable water inlet member 20 and the discharge port 12 at the downstream end starts to flow all at once in the direction of the discharge port 12 at the downstream end due to potential energy. The subsequent operation is the same as in the first embodiment. In addition, in the case of the water inlet upstream check valve member 30B, when the water in the siphon water supply hose 10 between the open / close type water inlet member 20 and the discharge outlet 12 at the downstream end begins to flow all at once in the direction of the discharge outlet 12 at the downstream end due to potential energy, the air and water upstream of the water inlet upstream check valve member 30B are sucked in downstream, and at the same time new water in the water storage section 1 is sucked in through the water intake 11 and flows down to the discharge outlet 12 at the downstream end and discharged, activating the siphon action.

[0031] According to this invention, as in the first embodiment, the water inlet opening and closing device 210 provided at the water inlet 11 at the most upstream portion, which was essential in conventional siphon devices, is eliminated, so that dangerous work in water to open and close the opening can be avoided. Also, since the opening and closing device 230 provided at the discharge port 12 at the most downstream portion is eliminated, the work of opening and closing the opening and closing device 230 can be omitted. Also, a small-diameter water injection hose 40 having an aperture smaller than the siphon water supply hose 10, which is connected to a small-diameter water supply device having an aperture smaller than the siphon water supply hose 10, can be connected to the open-close type water injection port member 20 to inject water into the siphon water supply hose 10 and start the siphon.

[0032] Third embodiment The siphon water supply device 120 according to the third embodiment will be described in detail with reference to the drawings. The siphon water supply device 120 according to the third embodiment is shown in FIG.

[0033] Of the configurations of the siphon water supply device 120 in the third embodiment, the configurations of the siphon water supply hose 10, the open / close type water inlet member 20, the water inlet upstream opening / closing member or the water inlet upstream check valve member 30, the water inlet hose 40 connected to the water inlet 21, the water inlet opening / closing lever 21A, and the water supply equipment 50 are the same as those in the first embodiment, so description thereof will be omitted.

[0034] The siphon water supply device 120 according to the third embodiment differs from the siphon water supply device 100 according to the first embodiment in that a discharge flow rate adjustment device 70 capable of adjusting the flow rate of water discharged to the downstream end of the siphon water supply hose 10 is provided. By adopting such a configuration, it is possible to inject water from the opening using the water supply device 50 without connecting the water injection hose 40 to the open-close water inlet member 20, or to manually inject water into the siphon water supply hose 10 using a container such as a bucket to start the siphon.

[0035] By providing a discharge flow rate adjuster 70 at the downstream end of the siphon water supply hose 10, it is possible to adjust the amount of water supplied after the siphon is activated. At the same time, when water is poured using a small-diameter water injection hose 40A having a smaller diameter than the siphon water supply hose 10 connected to a small-diameter water supply device 50A having a smaller diameter than the siphon water supply hose 10 as shown in FIG. 5, or when water is poured manually through the open-close type water inlet member 20 using a container such as a bucket, by closing the discharge port 12 without using the internal hose blocking member 60, water is poured and collected in the siphon water supply hose 10 in sequence from the downstream end, and when the siphon water supply hose 10 is filled to its highest point, the discharge flow rate adjuster 70 and the water inlet upstream opening and closing member 30A can be opened to activate the siphon action in the same way as in the first or second embodiment. Furthermore, in the case of the water inlet upstream check valve member 30B, when the siphon water supply hose 10 is filled with water, opening the discharge flow rate adjustment device 70 causes the water in the siphon water supply hose 10 to begin flowing downward due to potential energy, which in turn causes the air upstream of the water inlet upstream check valve member 30B and the new water from the water storage section to push open the opening / closing valve inside the water inlet upstream check valve member 30B and flow downward, activating the siphon action as in the first or second embodiment. In addition, when pouring water into the siphon water supply hose using a bucket or the like with the opening of the open-close type water inlet member 20 open, when the siphon water supply hose 10 is filled with water to its highest point, the opening of the open-close type water inlet member 20 can be closed and then the discharge flow rate adjustment device 70 and the water inlet upstream opening-close member 30A can be opened.In the case of the water inlet upstream check valve member 30B, when the siphon water supply hose 10 is filled with water to its highest point, the opening of the open-close type water inlet member 20 can be closed and then the discharge flow rate adjustment device 70 can be opened, thereby activating the siphon action in the same way as in the first or second embodiment. [Industrial Applicability]

[0036] As shown in the above-mentioned embodiment, it can be used as a device for safely, cheaply and efficiently draining water from reservoirs such as rivers, lakes, sand dams, glacial lakes, etc. In addition, since it operates by siphon action, it can significantly reduce electricity consumption and greenhouse gas emissions associated with power generation, which can greatly contribute to preventing global warming, building a decarbonized society, and achieving carbon neutrality.
