Description

[Technical field]

[0001] The present invention relates to a siphon water supply device and siphon water supply method in which a siphon start-up water supply unit is formed by combining and integrating various water injection members and water suction members required to constitute a siphon water supply device necessary for siphon water supply work at the most upstream part of a siphon pipe (hose) with a water injection unit using a water supply device and a siphon water suction unit, the siphon start-up water supply unit is immersed in a water storage unit of a high water level, and a siphon water supply pipe (hose) connected to the downstream part of the water injection junction member that constitutes the siphon start-up water supply unit is laid through the highest part of the piping to an outlet in a low water level area, and in the case of a reservoir constructed of straight walls, the siphon start-up water supply unit is hung from the top end of the straight wall or the like and the combined siphon start-up water supply unit is fixed within a storage framework and the storage framework main body is suspended. [Background technology]

[0002] A siphon water supply device is a device that uses a tubular member installed between a water storage section in a high water level area and a low water level area to supply water from the water storage section in the high water level area to the low water level area by siphon action. The inventor has proposed a water injection and confluence member as one of the members that activates and operates the siphon action (Patent Document 1).

[0003] The inventor has invented and obtained a patent for a siphon water supply device that connects a siphon water supply pipe (including a hose) directly to a water supply device to supply water, and when the water supply pipe is full of water, stops the power supply device and switches to siphon action. However, this siphon water supply device uses a submersible pump as the water supply device, and after switching to siphon water supply, the water supply device (submersible pump) becomes the siphon water intake part, so if dirt gets stuck in the small holes of the strainer installed in the intake part of the submersible pump while the siphon is in operation, the water supply stops, and maintenance work to remove the dirt is necessary and troublesome. Therefore, a "Y"-shaped water injection merging component that is placed at the highest part of the piping has been developed. This water injection merging component has a structure in which a water injection pipe (hose) that pours water from the water supply device is connected to one of the upstream forks, and a siphon water intake pipe (hose) is connected to the other to merge in a Y shape, and the siphon water supply pipe (hose) is connected to the downstream side to supply water. One of the features of the structure of this water supply device is that the water supply device's water inlet pipe and the siphon's water suction pipe are constructed separately, eliminating the need to attach a strainer to the siphon water inlet, and the siphon water inlet can be opened wide, preventing debris from clogging the water inlet hole during siphon water intake. Since it is difficult for the siphon to supply water by itself when the head exceeds 7m, the inventor discovered that in that case, the siphon action can be sustained even at high heads by using a water supply device in combination with the siphon action to inject water into the water inlet junction, and obtained a patent for this discovery.

[0004] When using the siphon water supply device according to Patent Document 1, the necessary components for the siphon water supply device, such as the water supply device, siphon water suction pipe, water suction dustproof basket, water supply device connection pipe, siphon water supply pipe, water injection junction member, and backflow prevention device, were delivered to the site before being assembled, and then assembled on site and immersed in the water storage unit in order for installation and use. Therefore, when used on site for the first time, it was difficult to assemble unless an experienced person provided technical guidance on the assembly procedure. In addition, as shown in Figure 12, the water injection junction member 130, which is approximately "Y" shaped or katakana "T" shaped, was installed near the highest part of the piping, so that two hoses, the submersible pump water injection hose 140 and the siphon water suction hose 150, were connected to the openings of the two branches of the water injection junction member 130 between the water reservoir 101 and the water injection junction member 130.

[0005] Furthermore, in the siphon water supply device described in Patent Document 1, although each component is connected, it is not possible to fix the individual components in the overall configuration obtained by assembling them together. Therefore, when installing against a vertical wall or a wall surface that is nearly vertical, each component of the siphon water supply device, such as a submersible pump, and the water injection and merging component, is attached with a hanging rope of an adjustable length, such as a wire rope, and further, for example, a length adjusting member such as a tamper evident, is used to hang the components so that the load is evenly distributed across each component, or the necessary scaffolding, anchoring, fixing materials, etc. are used for installation, and the device is installed as follows:

[0006] First, to install piping on a wall in the air, as shown in Fig. 13, anchors are driven into the wall and scaffolding 202 is assembled and fixed, and workers use this scaffolding 202 to install piping materials 203 such as hoses and tubular members. Next, anchor holes are drilled into the wall using connecting joints 204, and anchors 205 for fixing the piping materials are driven in to fix the piping materials 203. By repeating this process, piping materials 203 of a predetermined length are connected in order, and the piping length is extended. This work process has the disadvantage of being expensive to install.

[0007] Next, when piping is to be installed on a vertical wall underwater, a diver drills holes in the wall underwater to provide anchor holes, and installs piping anchors 206 in the holes using a filler such as Chemical Anchor (registered trademark), as shown in Figure 13. Pipe materials 203 of a specified length are connected in sequence using connecting joints 204 to extend the piping length. This kind of underwater anchor hole drilling work is harder than one might imagine, and only qualified personnel can carry out the work, which creates the problem of high construction costs.

[0008] [Patent Document 1] JP 2014-196656 A Summary of the Invention [Problem to be solved by the invention]

[0009] The present invention has been made in consideration of such problems. First, in order to enable the use of a siphon and a water supply device in combination when the head is 7m or more, a structure is provided in which a water supply device is connected directly or via a water supply device connection pipe to one of the two branches of a "Y"-shaped water injection junction member located at the highest part of the piping. With this structure, the other siphon suction pipe (hose) is also placed underwater, so that the siphon action can be activated without being limited to a head of 7m or less. In other words, even if the head is 7m or more, water can be injected above the highest part of the piping with a head exceeding 7m by activating a water supply device with a water supply function to a head of 7m or more. As soon as the water that has passed through the highest part reaches the discharge port at the downstream end, the siphon suction action from the siphon suction pipe (hose) installed at the other branch of the water injection junction member is activated, so the amount of water supplied is significantly increased by the water supply operation using both the water supply device and the siphon water supply operation. As a guideline for this amount of water increase, the water supply function curves provided by various submersible pump manufacturers show that, for example, in the case of the Tsurumi Manufacturing Co., Ltd. submersible pump KTZ43.7, when using a siphon and a submersible pump together to carry out water supply work at a site with a head of 10m, the water supply volume when using the submersible pump alone is 1.0m 3 / min, but when used in conjunction with the siphon effect, the maximum head is 10m - 7m (maximum head) = 3m, so the value for the water supply function with a head of 3m can be read from the graph as 1.4m. 3 / min, which means that one submersible pump can be operated to pump 1.4 times the amount of water. If the head is 7m or less when the siphon action is activated, the siphon flow will be automatically activated by the switching valve inside the water injection merging component when the water supply equipment is stopped. Also, if the head is 7m or more, the water supply work can be performed in combination with the siphon action by continuing to use the water supply equipment. As an example of water supply work using this siphon and water supply equipment in combination, in the trial calculation of the water supply work for construction work at a dam, if a 200mm diameter submersible pump was used alone, 23 submersible pumps would have to be operated for six months, but if the same 200mm siphon and submersible pump were used in combination, 13 pumps could be used to pump the same amount of water. The fuel costs of continuing to operate 23 submersible pumps and operating 13 pumps in combination with the siphon can be used to perform the water supply work of 23 submersible pumps, which significantly reduces fuel costs. In addition, by placing the water injection junction member underwater, two hoses between the water and the water injection junction member, which were always necessary in the previous patented technology, are no longer necessary, and it is possible to configure it with just one hose. A water supply device is connected directly or via a water supply device connection pipe to the connecting part of one opening of the bifurcated part on the upstream side of the water injection junction member, and a siphon water intake part equipped with a water intake dustproof basket is connected to the connecting part of the other opening as necessary, and a siphon water supply pipe (hose) that supplies water injected by the water supply device or water absorbed by siphon is connected and extended to the connecting part that is one opening on the downstream side of the water injection junction member, and it is possible to configure it with one water supply hose through the highest part of the piping to the downstream discharge outlet, so that it is possible to omit the material of the water supply hose. In addition, the siphon water supply device and siphon water supply construction method are achieved by assembling these siphon start water supply members such as the underwater pump and the water injection junction member together as a siphon water supply device within a storage frame, and then immersing the storage frame with all the members fixed in place in the water storage part as it is. If the slope within the reservoir is gentle, the storage framework can be placed on the slope and installed underwater, or floats can be attached to the storage framework so that it floats at a constant depth even if the water level fluctuates, and it can be installed using a crane or other device at any location away from the shore.Furthermore, when installing against a vertical or nearly vertical wall surface, a siphon water supply device is proposed that uses a storage frame method in which the siphon activation water supply member is fixed inside the storage frame and the storage frame is suspended by a wire rope or the like, as well as a water supply construction method using the siphon water supply device that employs this suspended storage frame, thereby making it possible to shorten the construction period and reduce construction costs by eliminating the need for scaffolding materials and their assembly work, the work of fixing the water supply pipe to the wall, etc., which were previously required. Another object is to eliminate the need to go to the site to provide technical guidance for assembly work, etc., by shipping the storage frame with the necessary parts for the siphon water supply device assembled and fixed inside it at the shipping source. [Means for solving the problem]

[0010] In order to achieve the above-mentioned main object, the present invention adopts the following means. The siphon water conveying device according to the present invention is A siphon water conveying device that conveys water from a water storage section in a high water level area to a low water level area located lower than the high water level area, A siphon start water supply unit is integrated with a water injection and merging member that is made in a substantially "Y" shape or a substantially "T" shape, a water supply device that is connected directly or via a water supply device connection pipe to one of the openings of the upstream branch of the water injection and merging member, and a siphon water intake that is connected to the other opening, The opening of the water injection merging member is provided with a siphon water supply pipe which is a single-pipe extending from the highest part of the pipe to a downstream discharge port, the siphon start water supply unit is immersed in water and installed with the siphon water supply pipe connected, and a siphon stop air suction member is provided at or near the highest part of the siphon water supply pipe, It is characterized by being used alone as a siphon when the head is 7m or less.

[0011] In the case of a head of 7m or less, after the siphon water supply pipe is filled with water by the water supply equipment, the siphon flow will automatically start due to the function of the switching valve inside the water injection junction component when the water supply equipment is stopped.

[0012] The present invention also provides a siphon water conveying device that conveys water from a water storage unit in a high water level area to a low water level area that is lower than the high water level area, comprising: A siphon start water supply unit is integrated with a water injection and merging member that is made in a substantially "Y" shape or a substantially "T" shape, a water supply device that is connected directly or via a water supply device connection pipe to one of the openings of the upstream branch of the water injection and merging member, and a siphon water intake that is connected to the other opening, The opening of the water injection merging member is provided with a siphon water supply pipe which is a single-pipe extending from the highest part of the pipe to a downstream discharge port, the siphon start water supply unit is immersed in water and installed with the siphon water supply pipe connected, and a siphon stop air suction member is provided at or near the highest part of the siphon water supply pipe, It is characterized by the fact that when the head is 7m or more, the siphon water supply function and the water supply equipment function are used in combination.

[0013] In order to enable the use of a siphon and water supply device together when the head is 7m or more, a structure was created in which the water supply device is connected directly or via a water supply device connection pipe to one of the two branches of the "Y" shaped water injection junction component located at the highest part of the piping. With this structure, the other siphon suction pipe (hose) is also placed underwater, so the siphon action can be activated without being limited to a head of 7m or less.

[0014] The present invention also provides a siphon water conveying device that conveys water from a water storage unit in a high water level area to a low water level area that is lower than the high water level area, comprising: a water injection and merging member formed in an approximate "Y" shape or an approximate "T" shape; a water supply device connected to one of the openings of the upstream branch of the water injection and merging member via a siphon backflow prevention member and a water supply device connection pipe; and a siphon water intake connected to the other opening; The opening of the water injection merging member is provided with a siphon water supply pipe which is a single piping that extends from the highest part of the piping to the downstream discharge port, and in a state where the siphon water supply pipe is connected, the siphon start water supply unit is provided with a siphon backflow prevention member in the air and at least the water supply device and the siphon water intake duct immersed in water, and a siphon stop air intake member is provided at or near the highest part of the siphon water supply pipe, It is characterized by being used alone as a siphon when the head is 7m or less.

[0015] The water supply device according to the present invention has a siphon backflow prevention member, which is installed in the air. By installing it in this way, when the head is 7m or less and the upstream side of the submersible pump is in the air, the siphon backflow prevention member is combined with the siphon backflow prevention member, and when the submersible pump is stopped with the siphon water supply pipe filled with water, the siphon backflow prevention member is contracted by atmospheric pressure to cut off the flow of the submersible pump and prevent the flow of water sucked by the siphon from flowing into the submersible pump.

[0016] Furthermore, in the water supply device of the present invention, the siphon start-up water supply section may be integrally constructed with the necessary combination to form a siphon start-up water supply section selected from the water supply equipment, the siphon water intake port, the siphon water intake dustproof basket, the water supply equipment connecting pipe, the siphon water supply pipe, and the water injection merging member, and may be placed underwater in the water storage section while being stored and fixed within a storage framework.

[0017] According to the siphon water supply device of the present invention, in which the storage framework itself is suspended, the necessary components, such as the water supply device, siphon suction pipe, water supply device connecting pipe, water injection merging component, and backflow prevention device, required for starting the siphon are assembled and fixed in the siphon water supply components as the siphon start water supply device in the suspension storage framework, so that the suspension storage framework itself can be placed in the water storage unit while being suspended. This prevents the various siphon components from hanging from the water supply hose itself in a high water level area with a vertical or nearly vertical wall surface, which would cause the hose to be torn off and damaged by the load, and allows the siphon start water supply unit to be installed easily, safely, and quickly.

[0018] In the hanging type siphon water supply device according to the present invention, the storage framework for hanging may be characterized by comprising a front side hanging framework formed in a substantially rectangular shape, a wall side impact protection type hanging framework that is placed on the wall side when hanging, and a connecting framework that connects these at a predetermined interval. By creating a storage framework for hanging in a box shape that protects the outside of the siphon activation water supply unit with a framework, the siphon water supply equipment can be reliably protected and the siphon activation water supply unit can be prevented from being damaged by collision with the wall surface when hanging.

[0019] Furthermore, in the hanging type siphon water supply device according to the present invention, the wall-side impact protection hanging framework of the storage framework may be provided with an expanded metal lattice or mesh-like base member for fixing members. By attaching the base member for fixing members, each of the members constituting each siphon activation water supply unit, such as the submersible pump, the water injection junction member, the siphon intake unit, and the water intake dustproof basket of the siphon intake unit, can be securely fixed to a desired position on the hanging storage framework with a fastening member such as a wire or a resin or metal cable tie.

[0020] Furthermore, by attaching a lattice-shaped steel frame or a mesh-shaped expanded metal to all six surfaces of the box-shaped hanging storage framework, the mesh can function as an anchor for binding the various siphon components when fixing them inside the hanging storage framework, and can also prevent dirt from being sucked in by the water supply equipment or the siphon intake section.

[0021] Furthermore, in the siphon water supply device of the present invention, the wall-side impact protection type hanging framework may be characterized in that a hanging impact protection type framework reinforcing member is installed on the wall-side impact protection type hanging framework to reinforce the wall-side impact protection type hanging framework and at the same time to create a space between the ground and the base member for fixing the member when the siphon water supply equipment is installed on a horizontal ground to arrange and fix the siphon water supply equipment in the storage framework. By providing such a suspension frame reinforcement member, when the suspension frame reinforcement member is temporarily placed in contact with the surface of a flat place such as the ground and each component constituting the siphon water supply device, such as the submersible pump, water injection junction component, siphon water intake section, and water intake dustproof basket for the siphon water intake section, is securely fixed in the desired position of the suspension storage framework, when each component is placed at the position of any mesh of the expanded metal and fixed with a fastening member such as a wire (wire) or a resin or metal cable tie, the suspension frame reinforcement member provides a space between the ground and the expanded metal, making it easy to pass the tip of a fastening member such as a fastening band from the front side of the expanded metal to the ground side and back again. In other words, when fixing the siphon component to be fixed with the fastening member, the tip of the fastening member can be passed through the mesh of the expanded metal to the ground side, then folded back to the adjacent mesh and easily folded back to the front side where the siphon components are tied together. Furthermore, the strength of the storage framework for hanging the siphon water supply device can be improved, and by providing the hanging frame reinforcing member on the wall side, even if the hanging storage framework collides with the wall surface, damage to the main body consisting of the frame material part of the hanging storage framework, which would be caused by the hanging frame reinforcing member colliding first, can be prevented or reduced.

[0022] Furthermore, in the hanging type siphon water supply device according to the present invention, the hanging storage framework may be provided with a hanging hook for use in hanging the hanging storage framework. By adopting such a configuration, the hanging storage framework body can be easily hung by hooking a wire or the like onto the hanging hook.

[0023] Furthermore, a water supply method using the hanging siphon water supply device according to the present invention is provided. That is, the water supply method according to the present invention is characterized in that the water in the water storage unit in the high water level area is moved to a low area located at a lower place using the above-mentioned hanging siphon water supply device. According to this water supply method, the installation is easy and the installation cost can be reduced, and the construction period can be shortened and the hanging siphon water supply device can be constructed and water can be supplied by quickly installing it. In addition, since the suspension storage frame in which each component constituting the siphon is fixed and integrated to the suspension storage frame is suspended by a wire rope, the underwater pump and the water injection merging component are not hung from the water supply pipe (water supply hose) member, and damage to the water supply pipe (water supply hose) member can be prevented.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0025] (First embodiment) Next, the siphon water supply device 100 according to the first embodiment will be described in detail with reference to the drawings. The storage frame type siphon water supply device 100 according to the first embodiment is shown in FIG. 1. FIG. 2 is an enlarged view of part A in FIG. 1, and is a combination diagram of the siphon start water supply part 14 arranged on the water storage part 1 side among various members constituting the siphon water supply device 100. The siphon start water supply part 14 refers to a combination of members arranged in the water storage part 1 among members necessary for starting the siphon, and refers to a combination selected from the water supply device 20, the siphon water intake port 11a, the water supply device connection pipe 12, the water injection merging member 30, and the siphon water intake dustproof basket 15.

[0026] As shown in Fig. 1 and Fig. 2, the siphon water supply device 100 according to the first embodiment mainly includes a water supply device 20 such as a submersible pump for starting the siphon water supply device 100, a siphon water suction pipe 11 having a siphon water intake 11a for suctioning water from the water storage section 1 in the upstream or high water area, a water supply device connecting pipe 12 connected to the water supply device 20, a siphon water supply pipe 13 arranged on the downstream side, and a bifurcated water injection merging member 30 connecting these pipes. In this embodiment, the water supply device 20, the siphon water intake 11a, the water supply device connecting pipe 12, and the water injection merging member 30 are arranged in the water storage section 1 in the high water level area, and these constitute a siphon start water supply member 14. A part of the siphon water supply pipe 13 is arranged in the water storage section 1, and the discharge port 13a of the siphon water supply pipe 13 is installed at a position lower than the water level 1a of the water storage section 1 so that the siphon action can be exerted.

[0027] The water injection and merging member 30 has a first opening 37, which is an opening on one side on the upstream side, connected to a siphon suction pipe 11, and a second opening 38, which is an opening on the other side, connected to the water supply device 20 directly or via a water supply device connecting pipe 12. Of the siphon water supply device 100, each member (siphon activation water supply member 14) disposed in the water storage section 1 is assembled and then used by immersing the entire member in water.

[0028] The pipe members used in the siphon water supply operation, such as the siphon water suction pipe 11, the water supply device connection pipe 12, and the siphon water supply pipe 13, are made of hard hoses or pipe materials whose cross-sectional shape does not easily deform. Examples of hoses made of hard materials include what are commonly called suction hoses, hoses made of hard polyethylene or polyvinyl chloride, and steel pipes. The siphon water suction pipe 11 is placed in a water storage section 1 such as an upstream area or a high water area, such as a pool, pond, swamp, river, or dam. A siphon water suction dustproof basket 15 is provided at the siphon water suction port 11a at the tip.

[0029] The water conveying device 20 is a pump with a water conveying function that is operated by electricity, and is attached to the tip of the water conveying device connection pipe 12. The water conveying device 20 can be turned on / off by a switch (not shown) on a distribution board to which the power source of the generator or system is drawn.

[0030] As shown in FIG. 3, the water injection junction member 30 is bifurcated on the upstream side, and has a first opening 37 connected to the siphon suction pipe 11, a second opening 38 connected to the water supply device connection pipe 12, and a third opening 39 connected to the siphon water supply pipe 13. The water injection junction member 30 is formed so that the water passages of the first opening 37 and the second opening 38 join at an acute angle. For example, it is formed into an approximate Y shape of the alphabet as shown in FIG. 3, or an approximate T shape of the Japanese katakana as shown in FIG. 4. The end of each opening (37-39) of the water injection junction member 30 is equipped with a flange having a connection function, and as shown in FIG. 2, the openings (37-39) can be easily and firmly connected to the pipes by using the flange. Furthermore, since the water injection and merging member 30 used in this embodiment is immersed in water, even if the welded parts are not completely airtight during production, the siphon action will not be affected at all because it will only suck in water rather than air through the weld gaps, allowing the siphon action to continue.

[0031] As shown in Fig. 3, a switching valve 35 is provided inside the joining point of the first opening 37 and the second opening 38. This switching valve 35 has the effect of preventing the flow of water from the first opening 37 side from flowing into the second opening 38 side, and preventing the flow from the second opening 38 side from flowing into the first opening 37 side. When water flows from both the first opening 37 and the second opening 38, the angle of the switching valve 35 moves in proportion to the flow rate and flow speed of the water flowing from each opening side and joining together.

[0032] In addition to the substantially "Y" shape, the water injection and merging member 30 may have a structure shaped like the Japanese katakana "T" as shown in Fig. 4, in which a side pipe member 32 for injecting water into a water supplying device is joined and attached to the side of a straight-tube-shaped siphon main pipe member 31. The side pipe member 32 for injecting water into a water supplying device may have a junction cutout piece 33 generated when the side of the straight-tube-shaped siphon main pipe member 31 is cut out to provide a junction, and the junction with the side pipe member 32 for injecting water into a water supplying device may be attached to the junction with a hinge or the like so as to open and close the opening on the side of the siphon main pipe member 31. The junction cutout piece 33 generated when the junction of the siphon main pipe member 31 is cut out naturally substantially matches the shape of the opening of the junction on the side of the siphon main pipe member 31, so that by attaching this to the junction via a hinge 34 as a junction changeover valve 35, a changeover valve 35 of an appropriate size that matches the shape of the opening of the junction can be obtained. The switching valve 35 may be a newly processed one rather than being a reused piece of cut-out straight pipe.

[0033] Also, a siphon stop air intake member 80 is provided at or near the highest part of the siphon water supply pipe 13. The siphon stop air intake member can be opened and closed to prevent air from entering the siphon water supply pipe 13 or to supply (intake) air. Therefore, when it is desired to stop the siphon water supply, the opening of the siphon stop air intake member 80 is opened, and air is sucked in from the opening, and the water in the siphon water supply pipe 13 can be separated by the air, and the siphon water supply action can be stopped. In the siphon water supply device according to this embodiment, the siphon start water supply member 14 is disposed in the water storage section 1, and therefore it is an important member as a device for stopping the siphon outside the water storage section 1. The siphon stop air intake member 80 can be arbitrarily adopted in the second to fourth embodiments described below.

[0034] As described above, according to the siphon water supply device of this embodiment, as shown in Fig. 12 showing a previously developed technology, a two-way pipe was installed from the water where the water supply device 20 and the siphon suction pipe 11 were installed to the water injection junction member 30 using two hoses, the submersible pump water injection hose 140 and the siphon water suction hose 150, but instead a single pipe can be installed from the water. Also, the siphon water supply equipment required to start the siphon, such as the water supply device 20, siphon water intake 11a, water supply device connecting pipe 12, and water injection junction member 30, can be arranged in one place inside the water storage section 1.

[0035] As shown in Fig. 5, an air backflow prevention member 60 made of a hose made of a flexible material may be provided at or near the discharge port 13a. If the discharge port 13a is made of a hard material, when the amount of water decreases due to the siphon action, a space is created above the discharge port 13a of the downstream siphon water supply pipe 13, and air may flow in from there, reach the highest part of the piping, and accumulate, causing the siphon action to stop. However, by providing an air backflow prevention member 60 made of a hose made of a flexible material, the cross section of the hose changes depending on the amount of water discharged from the discharge port 13a, and it is possible to prevent the creation of a space through which air can flow back.

[0036] The siphon water supply device 100 according to the first embodiment is not only used when the head is 7m or less, but also when the head is 7m or more, and also when the head is 20m or more depending on the conditions of the site. In such a site condition, if the head exceeds 7m, negative pressure will be generated at the highest part of the pipe when the siphon water supply action alone is used, and the water in the water supply pipe at the highest part of the pipe tries to flow down by dividing into the downstream side and the upstream side due to their own weight, so a large negative pressure will be generated at the highest part of the pipe, and a cavity will be generated due to the evaporation phenomenon of water, and the siphon will stop. Therefore, if the water that tries to flow down to the upstream side is pushed up to the highest part of the pipe by the water pressure of the submersible pump water supply operation, the cavity at the highest part of the pipe will disappear, and water will be connected to the water supply pipe, and the siphon water supply operation will continue. In other words, at a site where the head is 7m or more, if the submersible pump water supply operation is stopped, a cavity will be generated at the highest part of the pipe and the siphon action will stop, so the submersible pump water supply operation is an indispensable siphon water supply operation. The siphon water pumping method, which keeps the submersible pump running, seems to be no different from the conventional submersible pumping method in terms of cost and environmental impact. However, the method of siphon water pumping using this siphon and submersible pump in combination has the following major advantages. According to a trial calculation, the pumping speed can reach 1.0 m per second at a site with a head of 18 m. 3 At a site where discharge of 2.85 m is required, a Φ200mm submersible pump can deliver 2.85 m 3 / min, 22 pumps had to be operated 24 hours a day for six months, but the water discharge rate was 4.9 m / min when using a Φ200mm siphon and a Φ200mm submersible pump in combination. 3 / min, only 13 units will be required. The fuel required to operate the submersible pumps will be reduced by 889,200L (4,446 drums), which is equivalent to the fuel required for nine submersible pumps. In addition, the reduction in fuel consumption will reduce greenhouse gas emissions by 2,700kg of CO2. 2 This has made it possible to reduce the occurrence of

[0037] Second embodiment Next, the siphon water supply device according to the second embodiment will be described with reference to the drawings. The siphon water supply device 100 according to the second embodiment is a storage frame type siphon water supply device 100 in which necessary members are assembled and fixed in a storage frame 90, as shown in Fig. 6. The storage frame type siphon water supply device 100 according to the second embodiment is mainly equipped with a water supply device 20 such as a submersible pump for starting the siphon water supply device 100, a siphon water intake port 11a for suctioning water from the water storage section 1 in the upstream area or high water area, a water supply device connection pipe 12 connected to the water supply device 20, and a siphon water supply pipe 13 arranged on the downstream side, and a water injection merging member 30 connecting them, as shown in Fig. 7. The second embodiment differs from the first embodiment in that an installation method is adopted in which siphon activation water supply components 14, such as the siphon intake 11a, the water supply equipment connecting pipe 12, the water supply equipment 20, and the water injection merging component 30, are assembled and fixed within a storage framework 90, and then immersed in water for installation.

[0038] In this embodiment, as shown in Figures 6 and 7, the upstream end of the siphon water supply pipe 13 is connected to the third opening 39 of the water injection junction member 30, the siphon water intake 11a is connected to the first opening 37 of the water injection junction member 30, and the water supply equipment 20 is connected to the second opening 38 via the water supply equipment connecting pipe 12. These siphon-activated water supply members 14 are stored in a hanging storage framework 90 and fixed in place. The hanging storage framework 90 with the siphon-activated water supply member 14 fixed thereto is then hung and the entire hanging storage framework 90 is immersed in water to supply water.

[0039] As shown in Fig. 8, the hanging storage framework 90 includes a front hanging framework 91 formed in a substantially rectangular shape, a wall side shockproof hanging framework 92 that is placed on the wall side when hanging, and a connecting framework 93 that connects them at a predetermined interval. The size of the hanging storage framework 90 is preferably about 1500 cm wide x 800 cm deep x 2500 cm high. Of course, this size is not limited. The wall side shockproof hanging framework 92 is provided with a wire mesh 94 such as expanded metal or wire lath as shown in Fig. 7. The siphon water supply equipment is fixed to the wire mesh 94 using fastening members 95 such as wires or metal cable ties. Furthermore, by attaching a lattice-shaped steel frame or a net-shaped expanded metal to all six surfaces of the box-shaped hanging storage framework, the net-like shape serves as an anchor for fastening various siphon components in the hanging storage framework 90, and prevents the intake of dust during the water intake work of the water supply device or the siphon water intake section. Optionally, a hanging frame reinforcing member 96 may be installed to reinforce the wall-side impact protection type hanging framework 92. Also, the hanging storage framework 90 is provided with a hanging hook 97 used for suspending the hanging storage framework 90.

[0040] The siphon-activated water supply member 14 assembled, stored, and fixed in the hanging storage framework 90 as described above is immersed under the water surface using the hanging hook 97 of the storage framework 90 and the hanging wire 98A, as shown in Figs. 6 and 7. First, the work base 3 is installed at the highest part 2 of the piping using the fixing anchor 4, and the foundation surface is constructed. Then, using a heavy machine such as a crane, the hanging hook 97 of the storage framework 90 is used to hang the vertical wall surface or the side of a wall surface close to a vertical surface to the water surface of the high water level area. At this time, by hanging the hanging frame reinforcing member 96 so that it faces the wall surface, even if the storage framework 90 hits the wall surface, the possibility of the hanging storage framework 90 being damaged by the hanging frame reinforcing member 96 hitting the wall surface first can be reduced. When the siphon water supply equipment is fixed to the expanded metal, by placing the suspension frame reinforcing member 96 on the ground so that the bottom surface is the bottom surface, a space is provided between the ground and the expanded metal, so that the tip of the fastening member 95 can be passed through the mesh of the expanded metal to the ground side and then folded back on the mesh in the adjacent area to easily fold back on the front side where the siphon components are bound. Also, in order to prevent the gravity of the storage frame 90 in which the siphon water supply equipment is stored from being applied to the siphon water supply pipe (hose) 11, as shown in Fig. 6, a siphon water supply pipe lifting wire 98B for lifting the siphon water supply pipe 13 is adjusted to the length of the siphon water supply pipe 13 or less by using a connecting metal fitting (e.g., a turnbuckle) 99 for the siphon water supply pipe 13 in addition to the storage frame hanging wire 98A that hangs the storage frame 90. In this way, even if water flows through siphon water supply pipe 13, the gravity of the water is not directly applied to siphon water supply pipe 13, thereby protecting siphon water supply pipe 13. The lengths of storage framework hanging wire 98A and siphon water supply pipe hoisting wire 98B, and the length of siphon water supply pipe 13 are adjusted by arranging storage framework 90, siphon water supply pipe 13, storage framework hanging wire 98A, and siphon water supply pipe hose hanging wire 98B side by side on flat ground and combining them to adjust the lengths.After that, the upper ends of the storage framework suspending wire 98A and the siphon water supply pipe suspending wire 98B are hoisted using a crane to a height completely clear of the work area surface, moved above the water surface of the water storage section, and gradually lowered so that the storage framework 90 is set at the desired position and water depth. After that, the upper ends of the storage framework suspending wire 98A and the siphon water supply pipe suspending wire 98B are fixed to the work base 3, completing the installation work of the siphon water supply device 100.

[0041] Third embodiment A siphon water supply device 100 according to a third embodiment is shown in Fig. 9. In the above-mentioned embodiment, the siphon water supply equipment stored in the storage framework 90 is installed on a vertical wall surface or a wall surface close to a vertical surface, but this is not limited thereto, and as shown in Fig. 9, in the case where the surface to the water storage section is a gentle slope, a float 70 may be provided on the storage framework and the siphon water supply pipe 13 and placed in water.

[0042] Even when the float 70 is provided for installation in this manner, the equipment necessary for the siphon is assembled and stored within the storage framework 90, so that the siphon water supply device 100 can be easily and quickly installed.

[0043] (Fourth embodiment) Fig. 10 is a front view showing the outline of the configuration of a siphon water supply device according to the fourth embodiment. The fourth embodiment employs a method of combining the siphon water supply members according to the first embodiment with a siphon backflow prevention member 40 and an extension siphon suction pipe 11. The fourth embodiment is used when the head is 7m or less.

[0044] 11, the upstream end of the siphon water supply pipe 13 is connected to the third opening 39 of the water injection junction member 30, the siphon water suction pipe 11 is connected to the first opening 37 of the water injection junction member 30, and the water supply equipment 20 is connected to the second opening 38 via a siphon backflow prevention member 40 and a water supply equipment connecting pipe 12, and these are stored and fixed in a storage frame 90 for hanging, so that the upstream part including the water supply equipment is immersed in water. In this embodiment, since the siphon backflow prevention member 40 is combined among the various siphon components, an extension siphon water suction pipe 11 is combined to make the combined length uniform. By combining this siphon backflow prevention member 40, when the head is 7m or less and the upstream side of the submersible pump is in the air, and the siphon water supply pipe 13 is filled with water and the submersible pump is stopped, the siphon backflow prevention member 40 is contracted by atmospheric pressure to cut off the flow of the submersible pump and also prevents the siphon suction combination from flowing into the submersible pump. The storage framework 90 for hanging is not necessary.

[0045] When the water injection and merging member 30 is disposed in the air as in the fourth embodiment, it is advisable to provide a siphon backflow prevention member 40. As shown in FIG. 11, the siphon backflow prevention member 40 is provided between the water injection and merging member 30 and the water supply equipment connecting pipe 12 to prevent water from flowing back toward the water supply equipment 20. The siphon backflow prevention member 40 is made of a hose made of a soft material. When the forced water supply by the electric power from the water supply equipment 20 is turned off and the water in the siphon water supply pipe 13 arranged downstream of the highest part 2 of the piping flows down toward the discharge port 13a at the downstream end due to potential energy (gravity), the siphon backflow prevention member 40 draws in the water in the siphon water suction pipe 11 and flows downstream, so that the water in the water storage section 1 is sucked into the siphon water suction pipe 11 from the siphon water suction port 11a at the upstream end of the siphon water suction pipe 11. At this time, if the inside of siphon backflow prevention member 40 is not blocked and is hollow when passing through water injection junction member 30, water will flow around to the water supply device 20 side, and the water will pass through water supply device 20 and return to water storage section 1. At this time, if siphon backflow prevention member 40 is made of a hose made of a soft material, when the water injection work into siphon water supply pipe 13 is stopped, the water in water supply device connection pipe 12 and siphon backflow prevention member 40 will return to water storage section 1 by gravity, and the hose material of siphon backflow prevention member 40 made of a soft material will block the hose of siphon backflow prevention member 40 due to the negative pressure inside siphon backflow prevention member 40 and the external water pressure, preventing backflow toward the pump (water storage section 1) even if the siphon flow water approaches water injection junction member 30.

[0046] In addition, the siphon backflow prevention member 40 plays an important role when starting the siphon water supply operation. The hanging type siphon water supply device 100 according to the present invention uses the water supply device 20 connected to the water supply device connection pipe 12 to inject water into the siphon water supply pipe 13 via the siphon backflow prevention member 40 and the water injection merging member 30. When the siphon water supply pipe 13 is full of water and starts to flow, the water supply device 20 is stopped to stop the water supply operation. When the flow from the water supply device 20 is stopped, the water in the siphon backflow prevention member 40, which is made of a flexible material, tries to flow back down to the upstream water storage section 1 together with the water in the water supply device connection pipe 12. Therefore, the siphon backflow prevention member 40 becomes negative pressure and is pushed by the water pressure in the water storage section 1, causing it to become blocked. Due to this action, the water poured from the water supply device 20 flows down from the highest part 2 of the piping of the siphon water supply pipe 13 located downstream toward the downstream discharge port 13a due to potential energy. This flow acts to suck water from the water storage section 1 into the siphon water suction pipe 11 from the upstream siphon water suction port 11a. When this action works, if the water that has flowed into the water pouring junction member 30 flows in the direction of the siphon backflow prevention member 40 connected to the other side, the water will return to the water storage section 1, but this is prevented by the siphon backflow prevention member 40, so the water sucked by the siphon can flow in the downstream direction toward the discharge port 13a without changing direction and flowing toward the siphon backflow prevention member 40 inside the water pouring junction member 30.

[0047] In addition, the water injection junction member 30, which is constructed by joining the side pipe member 32 for injecting water into the water supply equipment to the side of the straight-pipe siphon main pipe member 31, has a siphon backflow prevention member 40 provided at the upstream opening of the bifurcated siphon main pipe member 31 and the side pipe member 32 for injecting water into the water supply equipment. When the siphon is started, the changeover valve 35 on the siphon intake side is closed and water is injected from the water supply equipment 20. When drainage from the low area side is confirmed, the water supply equipment's water injection is closed, and the changeover valve 35 on the siphon intake side opens, starting water supply by the siphon. [Industrial Applicability]

[0048] As shown in the above-mentioned embodiment, the present invention can be used as a device for safely, inexpensively and efficiently draining water from reservoirs such as rivers, lakes, sand dams and glacial lakes. [Explanation of symbols]
