Description

  The present invention relates to a siphon water delivery system for delivering water in high water area or water and soil to a low area. In particular, the present invention relates to a siphon water supply apparatus and a siphon water supply method capable of increasing a water supply amount by increasing a limit head.

  2. Description of the Related Art Conventionally, as a method of supplying water from a spring section such as a pond, a swamp, a river, or a pool, there is a method of supplying water using a water supply apparatus such as a submersible pump. In the case of the drainage method by this water supply apparatus, since the water supply apparatus is operated by electricity, drainage is possible even if the position of the discharge port of the drainage hose is higher than the water level of the spring part. Therefore, when carrying out drainage planning, it has been the only consideration whether the pump function can go over the lift to the top of the dike.

  In fact, many submersible pump manufacturers have been developing the main function of technical development of water supply equipment, focusing on "How to increase the amount of drainage for the lift at low cost." In other words, according to the manufacturer's idea, after pumping up the water, it will flow through the water channel as it flows naturally and be supplied to the fields according to the usage of the person who uses the water, and it will be good if the pool is filled with water Submersible pumps play a role by pumping up. When carrying out drainage plan also in construction work, if the lifting head to the height of the top end of the temporary closing dike is considered on the basis of the water level in the spring section, consider the submersible pump with drainage capacity that can exceed this height. Good. Therefore, as the piping condition that the height of the discharge port must be set lower than the water level of the spring as in the present invention, extra materials have to be used, so it is necessary to consider the drainage plan It was excluded from the matter.

  On the other hand, the operation of the submersible pump used to drain natural dams caused by landslides caused by earthquakes and heavy rains in the past had enormous costs such as fuel costs and fuel transportation costs by helicopters and the like. In response to this, various siphon water delivery systems have been proposed that can be effectively used even during disasters. However, according to the proposed method of activating the siphon water supply apparatus, the on-off valves at the upper and downstream portions of the siphon drainage hose are closed, the water inlet on-off valve provided at the pipe top is opened, and the submersible pump etc. Water injection is continued until the inside of the siphon drainage hose is full, and when the water is full, the water feeding device is stopped, the water injection port on-off valve is closed, and the on-off valves for the upstream water inlet and the downstream discharge port are opened. According to the water level in the spring portion and the difference in water head on the discharge port side, the water in the spring portion on the upstream side is sucked into the siphon drainage hose to flow down and drain to the discharge port side. The role of the motorized water supply device in this conventional siphon water supply device was only to supply water until the inside of the drainage hose was full. After that, when the siphon action was activated, the role of the water supply device was lost.

  However, drainage operation by siphon is limited to a lift of around 7 m. When the lift exceeds 7 m, vaporization phenomenon by negative pressure starts to occur in the top hose. Furthermore, when the lifting head becomes large, the inside of the water supply hose becomes hollow and the flow is divided, the water supply is stopped, and there is a problem that the drainage operation can not be performed. In an actual site, drainage may be necessary even at a head of 7 m or more depending on various situations. Therefore, when the lift is 7 m or more, there was no option other than performing the drainage work with the water supply equipment. However, if the fuel consumption of the submersible pump is “1”, the siphon can be drained at a low fuel consumption ratio of only “0.0007” even during start-up and maintenance, and siphon drainage can be performed up to 7 m head The benefits of implementing The siphon drainage system can secure nearly 87% of the displacement of the submersible pump without using electricity.

  Therefore, the present inventor combines or switches the drainage function of the siphon and the drainage function of the water supply equipment with the same drainage device by providing the merits of both the drainage work with the siphon action and the drainage work with the water supply equipment. It succeeded in establishing and developing the technology of the siphon drainage device which was able to do it, and also the drainage volume was increased by the high head more than 7m. Moreover, we succeeded in increasing the amount of drainage by the synergetic effect of using siphon action and water supply equipment together regardless of the lift.

Patent No. 5785634 gazette

  In order to solve the above problems, the present invention combines the functions of both siphon drainage and water feeding equipment drainage, so that drainage operations can be carried out far beyond the respective lifts so far, and the drainage operations at each lift can be carried out. A siphon water delivery system capable of greatly increasing the volume of each drainage is provided. Moreover, the air in a water supply hose can be removed efficiently, without raising the specification of a submersible pump, and the siphon water supply apparatus which can improve water supply efficiency is provided.

The present invention adopts the following means in order to achieve the above-mentioned main objects. The siphon water supply apparatus and the siphon water supply method according to the present invention are a siphon water supply apparatus using a siphon action, and there is a discharge port which is always opened at a position lower than the water surface of the spring section from the spring section through the lift pipe top section. The water hose of the material that can be held in the cross-sectional shape,
A water supply device disposed in the spring portion and connected to the water supply hose to supply water;
In the water supply device provided with
When the lift is about 7 m or less, to start the siphon action, the water feeding device is activated to feed water into the water feeding hose, and when the water feeding hose is in a nearly full water feeding state, the water feeding device is stopped. The flow in the water supply hose is operated by water supply operation by siphon.

  If the lift is about 7 m or less, start the water feeding equipment to start the siphon action, send "priming water" into the water feeding hose, and when the water hose cross section inside the water feeding hose is almost full of water feeding By stopping, it becomes possible to draw in the water of the spring part and operate the siphon water supply work by the atmospheric pressure and the potential energy of the priming water on the downstream side from the top of the pipe of the water supply hose. Further, according to the present invention, by performing water supply of the water supply apparatus also after siphon activation, the synergetic effect of both water supply capabilities can exert a water supply function exceeding individual functions. In addition, when starting the siphon of multi-row piping, after securing the waterproofness of the connection part of this water supply equipment and the water supply hose, the water supply equipment is removed and the water injection equipment merges the water injection equipment of the second and subsequent siphon water supply equipment. It will also be possible to use for water injection in the department. Of course, the water supply equipment may be provided for each pipe of the water supply hose.

Further, the siphon device and siphon water feeding method according to the present invention can maintain the cross-sectional shape in which the discharge port always opened at a position lower than the water surface of the spring portion from the spring portion through the lift pipe top Material water hose,
A water supply device disposed in the spring portion and connected to the water supply hose to supply water;
In the siphon water supply device provided with
When the lift is about 7 m or more, it is possible to add a water supply equipment water supply operation to prevent or eliminate the cavity that occurs with the vaporization phenomenon due to the negative pressure at the top of the pipe in the siphon water supply operation. The synergetic effect of the water supply device may be characterized in that water is supplied beyond the theoretical limit lift height and water transfer amount of the siphon, and the limit lift height and drainage amount of the water transfer device.

  The critical lift of the siphon function is about 7 m, but when the lift exceeds about 7 m, bubbles begin to be generated inside the top of the water supply hose tube due to evaporation due to negative pressure. However, as the lift increases, the generation of air bubbles becomes intense, and a phenomenon in which the inside of the water supply hose is eventually hollowed out and the flow is divided appears, and the water supply operation is stopped. This is because the water in the water supply hose on the upstream side and the downstream side of the tube top tends to lower by gravity, so that the negative energy works on the tube top and the vaporization phenomenon is caused by the negative pressure. However, the hollow portion is filled with water by additionally injecting water into the hollow portion of the stopped flow by the water feeding function of the water feeding device. As a result, the inside of the drainage hose from the upstream spring water reservoir to the discharge outlet on the downstream side is connected by water, and the water between the discharge outlet on the downstream side of the pipe top is going to flow down, and this potential energy is drawn As a result, the water in the spring section is sucked into the water inlet and flows through the water supply hose so that the siphon acts. That is, when the lift is 7 m or more, a hollow is formed at the top of the pipe, and it appears that the siphon action is stopped to the eye. However, since the energy of the siphon action continues to work on the upstream side and the downstream side of the tube top, if the cavity at the top of the tube is filled with the auxiliary water supply of the water supply equipment, the siphon action works and the siphon water supply operation resumes Do. In this way, not only the lift and flow rate of the siphon function is improved by the supplementary water transfer of the water transfer device, but the lift and flow rate of the water transfer device is also improved, and the synergy effect of each energy works and both functions are A greatly improved siphon water delivery system can be provided.

Furthermore, the siphon device and the siphon water delivery method according to the present invention are a siphon water delivery device using a siphon action, and a discharge port which is always opened at a position lower than the water surface of the spring portion from the spring portion through the lift pipe top portion. A water hose of a material capable of holding the cross-sectional shape on which the
A water supply device disposed in the spring portion and connected to the water supply hose to supply water;
In the siphon water supply device provided with
When the lift is about 7 m or less, the water feeding device is activated to feed siphon action to start the siphon action, and the water feeding hose is stopped when the water in the water feeding hose is almost full. The flow in the water supply hose can be operated by water supply operation by siphon,
When the lift is about 7 m or more, it is possible to add a water supply equipment water supply operation to prevent or eliminate the cavity that occurs with the vaporization phenomenon due to the negative pressure at the top of the pipe in the siphon water supply operation. The synergy effect of the water supply equipment enables water to be supplied beyond the theoretical critical lift height and water supply capacity of the siphon, and the critical lift height and drainage capacity of the water supply equipment,
It is characterized in that the water supply operation is performed by switching or using the water supply method by turning on and off the power supply of the water supply equipment at the boundary of the lift height of 7 m or more and 7 m or less.

  Thus, the siphon water supply method according to the present invention can operate the siphon water supply operation when the lift is approximately 7 m or less. This has a great effect as a drainage device that does not use electricity or fuel. On the other hand, when priority is given to increasing the amount of drainage without considering the electricity cost, fuel efficiency, etc. in an emergency such as a disaster, etc., even if the lift height is 7 m or less By performing the water supply operation, it is possible to provide a water supply device that exhibits a water supply function exceeding the individual water supply operation capabilities.

  On the other hand, even when the lift is about 7 m or more, adding the water transmission by the water transmission device while using the same water transmission device while using the same water transmission device, the synergistic effect of the siphon and the water transmission device makes the theoretical critical lift of siphon high. It is possible to send water that greatly exceeds the individual water delivery capacity, such as the water delivery volume, and the critical height of the water delivery equipment and the drainage volume. Therefore, according to the siphon water supply apparatus according to the present invention, the water supply operation by the synergy effect of the water supply equipment and the siphon action is switched according to the situation by turning on and off the power supply of the water supply equipment at a boundary of 7 m or more and 7 m or less. Alternatively, the water supply operation can be performed in combination.

  As described above, according to the rise and fall of the water surface of the spring, if the lift is 7 m or less, only the siphon function can be used to continue the drainage work, thus reducing the cost of fuel consumption and transportation and supply it can. This will also reduce greenhouse gas emissions. However, when it is necessary to give priority to a large amount of drainage, depending on the situation, it is possible to perform a large amount of drainage by synergetic effects by using a combination of siphon and water supply equipment to supply water. Even if the water level fluctuates and the head reaches 7 m or more, the same drainage device is used as it is and the water supply equipment function can be used together, so it can be used continuously with the siphon function by activating the water supply equipment function. .

  Thus, the present invention is a siphon water supply apparatus in which a siphon function and a water supply apparatus function are combined with a synergetic function. By using such a device, even if the water supply equipment of the same capacity is used, the synergetic effect of the siphon drainage action is added, the critical lift is increased, and the displacement is increased. Therefore, it is possible to send water even if the critical lift of the siphon is 7 m or more.

Moreover, the siphon water supply apparatus according to the present invention is a water supply capable of maintaining the cross-sectional shape, in which a discharge port constantly opened at a position lower than the water surface of the spring section from the spring section through the lift pipe top With the hose,
A water supply device disposed in the spring portion and connected to the water supply hose to supply water;
Equipped with
The water supply hose includes: a first opening connected to the water supply hose for absorbing water from the water supply part by a siphon action; and the water supply hose connected to the water supply equipment disposed in the water supply part It has a second opening connected, and a third opening connected to the water hose for sending water coming in from the first opening and the second opening to the downstream part. It is characterized by including a water injection merging member.

  When the water feeding equipment is stopped by combining the water intake hose on the water absorption side of the siphon from the side of the water delivery hose using the water injection joining member at the upstream portion of the water delivery hose of the siphon water delivery device, water absorption from the water delivery hose of the siphon water absorption side It is possible to switch to the water supply operation of discharging water from the discharge port of the downstream portion through the water injection merging member and supplying water to the downstream water supply hose. Thereby, when it switches to siphon water supply, it becomes the water supply from the siphon water absorption hose side mainly. For this reason, since it is not necessary to supply water through a complicated structure such as a screw inside the water supply apparatus when the water supply merging member is not used, the amount of water supply can be increased.

  In addition, in the case of a lift of 7 m or more, in addition to the siphon action, auxiliary water supply work is performed to prevent the generation of a cavity accompanied by a vaporization phenomenon on the pipe top of the water supply hose by the water supply equipment. In this case, if the water head difference is large, the flow rate of water absorbed by the siphon and passing through the water supply device is increased. When a large amount of water passes through the water supply apparatus by the siphon action, a phenomenon occurs in which a current for rotating the screw is left, which causes damage to the water supply apparatus due to the phenomenon of an over current. However, the structure of the present invention is provided with water-flowing portions on the water-feeding device side and the siphon water-absorbing side. Therefore, even if the flow rate by the siphon water absorption increases, the flow of the siphon will flow through the siphon water absorption hose to the water supply hose without passing through the water supply equipment. As a result, the amount of water supplied from the water supply device side is within the range of water supply according to the capability of the water supply device, so that generation of an over current can be prevented.

  Moreover, in the siphon water supplying apparatus according to the present invention, the water injection merging member provided in the water supplying hose of the water supplying apparatus may be provided at a position lower than the water level of the upstream water reservoir. In particular, by providing the water injection / consolidation member at a position lower than the water level of the upstream reservoir on the downstream side after passing the top of the lift pipe, water absorption by the siphon works reliably at the first opening, and water is sent downstream from the third opening Water flows steadily. By combining this with the water supply work of the water supply equipment, it is possible to carry out water supply work of a further increased amount.

  Furthermore, in the siphon water supplying apparatus according to the present invention, the direction of flow is switched to the junction of the flow of water from the first opening and the flow of water from the second opening in the water injection merging member. A switching valve may be provided which is pressed by the water pressure of each water flow to close the water passage portion of the other. By adopting such a configuration, it is possible to switch the flow of water from the first opening and the flow of water from the second opening by the water flow.

  Furthermore, in the siphon water supplying apparatus according to the present invention, the water injection merging member is configured such that the first opening or the second opening is not fully opened when the switching valve is pushed and moved by the water flow to switch the flow direction. In order to limit the movement range of the switching valve, a switching valve movement stopping member for stopping the switching valve may be provided.

  Furthermore, in the siphon water supplying apparatus according to the present invention, the flow of water by the siphon from the first opening and the water from the water supplying equipment from the second opening, together with or instead of the switching valve described above. In order to switch the flow direction, the first opening and the second opening may be provided with an opening check valve. That is, in the case of water supply by the water supply device, the check valve for the opening provided in the second opening is opened by the water pressure, and the check valve for the opening provided in the first opening is closed. Then, when the water supply device is stopped, the water pressure to the check valve for the opening provided in the second opening disappears, the check valve is closed, and the water is absorbed by the siphon from the first opening according to this. The check valve for the opening provided at the opening will be opened by water pressure to continue the siphon water supply operation. That is, the same effect as that of the switching valve described above is obtained.

  Furthermore, in the siphon water supplying apparatus according to the present invention, the water injection merging member switches the flow direction of water to any one or more of the first opening, the second opening, and the third opening. The opening / closing member for opening may be provided. With this structure, even when the water injection merging member is provided on the downstream side of the lift pipe top, the water injected from the second opening is closed through the first opening by closing the opening / closing device of the third opening. Water can be supplied to the water supply hose on the side to fill the inside of the siphon water supply hose. In this state, the opening / closing device of the first opening is closed, and at the same time, the opening / closing device of the third opening is opened, and water is supplied into the water supply hose by the water supply device. When the water supply hose is filled with water, stop the water supply equipment and open the opening / closing device at the first opening to prime the water in the siphon water supply hose on the siphon water absorption side to suck the water in the upstream water reservoir. Will act as This operation is particularly effective when the extension of the water supply hose connected to the third opening does not have a length twice or more the full length of the siphon water absorption hose connected to the first opening.

  Furthermore, in the siphon water supplying apparatus according to the present invention, the water supply hose connected to the third opening is a flexible hose when the arrangement position of the water injection merging member is provided at a position lower than the water level of the spring part. May be characterized. When the arrangement position of the water injection merging member is provided at a point lower than the water level of the spring portion, even if the water hose connected to the third opening is a flexible hose, the siphon from the spring reservoir to the first opening The action causes the flowing water to flow in the flexible hose, and the drainage operation is sustained. In addition, even after the siphon action is activated in the siphon water supply hose connected to the first opening, if the water supply device continues to use the water supply operation concurrently, the flexible water supply connected to the third opening is used. In the hose, water flows in a full condition by the water supply function of the water supply equipment. At this time, since the water in the siphon water absorption hose connected to the first opening is sucked into the third opening by the water flow of the second opening, the amount of water supplied is increased.

  Furthermore, in the siphon water supply apparatus according to the present invention, the water supply hose is at least a part of which is made of a flexible water supply hose having one or more members, and is connected between the water supply equipment and the water supply joining member It may be characterized in that. After the water supply from the water supply device is stopped, the flexible water supply hose is pushed to the atmospheric pressure and contracted to close the water passage, and the air pushing member is held in the flexible water supply hose, After water injection from the water supply device is stopped after being pushed downstream by water pressure from the water supply device, the water supply hose can be pushed to atmospheric pressure and contracted to close the water passage.

  Furthermore, in the siphon water supplying apparatus according to the present invention, the water injection merging member may be directly connected to the water supplying port of the water supplying device. By directly attaching the water joining member to the water inlet of the water feeding device, the water hose portion on the siphon side is also immersed in water when the water feeding device is immersed in the water of the spring portion. It will not remain. Therefore, stopping the water supply of priming water into the water supply hose by the water supply equipment can omit the process of pulling the air in the water supply hose on the siphon water absorption side with the energy of the priming flow downstream from the pipe top of the water supply hose. Since the inside of the siphon water absorption hose is full as it is when the water supply apparatus is stopped, the siphon action is activated as it is.

  Furthermore, in the siphon device according to the present invention, the water supply hose may not be connected to the siphon water absorption side of the water supply joining member. Since the water absorption hose is not connected to the first opening of the water injection merging member in the same manner as described above, the water injection merging member is also immersed in the water when the water supply device is immersed in the water of the spring portion. Therefore, when the water supply device is stopped, the water in the spring portion starts to be sucked directly from the first opening of the water injection merging member by the siphon action and the action to start flowing to the water supply hose can start and the siphon action can be activated. The process of discharging the internal air to the downstream portion can be omitted.

  Furthermore, in the siphon water supplying apparatus according to the present invention, the siphon water supplying apparatus has a vaporization amount for retaining water flowing in the water supply hose at a position lower than the top of the pipe and lower than the water level of the spring section upstream. A control valve or a vaporization control switch may be connected. When the siphon action is activated, in addition to the negative pressure generated in the water supply hose, the atmospheric pressure that is the external pressure causes the water supply hose to be crushed or cracked, etc., from the pipe top of the siphon drainage device It connects with a water supply hose at the position lower than the water level of a spring part downstream, and arrange | positions the valve for regulating evaporation amount. Thus, damage such as crushing or cracking of the water supply hose can be prevented by adjusting the generation amount of the vaporization phenomenon accompanying the negative pressure generated in the water supply hose after the siphon action is activated. In the case of a steep installation of the drainage water hose downstream of the pipe top, the flow is particularly oblique flow and water flows only at the bottom portion of the inner cross section of the water hose. That is, in the water supply hose, not the water but the gas vaporized under negative pressure will flow almost. In addition to this, the water supply hose is crushed by the atmospheric pressure which is the external pressure, and the water flow section is closed, and air is sucked into the water supply hose from the cracked part generated thereby, and the siphon phenomenon is stopped. By gradually increasing the shielding area of the vaporization amount adjustment valve of the siphon water delivery system to be larger than the cross sectional area of the vaporized gas occupying the upper part of the inner surface of the water delivery hose, temporarily part of the water flowing through the bottom of the water delivery hose. It can be made to stay. As a result, the amount of stagnation is gradually increased from the vaporization amount adjustment valve to the pipe top on the upstream side so that the water supply hose flows up to the pipe top in a full water state. As a result, the occurrence of oblique flow can be prevented, and the vaporization phenomenon can be almost eliminated. By eliminating the gas vaporized in the water supply hose and making the entire cross section a water flow, the influence of the external pressure of the atmospheric pressure can be reduced to prevent the water supply hose from being damaged. The purpose of the evaporation amount adjustment valve is not the switch for controlling flow rate generally, but the mixed flow phenomenon that occurs in steep water hoses has a remarkably high flow velocity, so the flow rate is extremely high. Even if it is closed by two or more minutes, the gas portion which occupies the upper part and the middle part of the inner cross section of the water supply hose is closed, and the flow rate is not affected so much. Lower the adjustment valve of the evaporation amount adjustment valve and let the adjustment valve reach a part of the upper part of the water flow at the bottom of the water supply hose and retain a part of the flowing water in the upstream part of the evaporation amount adjustment valve The flow rate of water discharged from the discharge port of the drainage hose is a large volume flow rate that is almost the same as when flowing the inner section of the gently sloping water hose with a full flow, since only the fullness reaches the top. It is.

Furthermore, in the siphon water feeding apparatus according to the present invention, the vaporization adjustment switchgear sandwiches the gate section, the gate section, and the encircling section surrounding the top and bottom and the left and right including the sliding space for the gate section. The sandwiching plate includes a pair of sandwiching plates provided with a plurality of holes around the flowing water hole and the flowing water hole to form a flange, a vertical movement bolt for moving the gate portion up and down in the surrounding portion and the sandwiching plate , May be characterized. With this structure, when connecting the vaporization adjustment opening / closing device and the water supply hose, the hole of the flange provided in the vaporization adjustment opening / closing device and the hole provided in the flange member provided at the end of the water supply hose are aligned Can be fixed firmly with a bolt and nut. The flange portion of the sandwiching plate extends the end of the sandwiching plate sandwiching the upstream and downstream sides of the gate to form a hole, and the upstream and downstream portions also function as the flange to connect to the pipe. The flange portion for pipe connection separately provided can be omitted, and weight reduction can be achieved by becoming flat as a whole.

  Furthermore, in the siphon water supplying apparatus according to the present invention, a water absorbing member is connected to the water absorbing port of the water supplying hose, and the water absorbing member is a float connected to at least one or more water supply member on / off valves and the water supply member on / off valve. And may be characterized. This is provided with a float on-off valve and a float on-off valve capable of adjusting the water level by automatically limiting the amount of drainage so that the water level in the spring water part does not fall below a certain level. That is, when the water level is lowered, the float is lowered and the interlock valve is closed to close the water intake. Further, when the water level rises, the float rises and opens the on-off valve, so that the water inlet can be opened. At the same time as the water level drops, the on-off valve closes, and when the water level rises again, the float rises and the on-off valve can be opened.

  Furthermore, in the siphon water supplying apparatus according to the present invention, when the water supply member on-off valve is opened, the water supply member on-off valve is pivoted to the inside of the water absorbing member. It may be one. Thereby, when the water level of the spring section rises and it is necessary to open the on-off valve, the on-off valve is structured to open along the flow toward the inside of the water absorbing member. The water pressure and the water pressure of the water depth in the spring section overlap to act as an open / close valve. Therefore, the float for opening the on-off valve can be made smaller.

  Furthermore, in the siphon water delivery apparatus according to the present invention, at least one or both of the water absorption hole of the water delivery apparatus and the water absorption port of the water delivery hose are disposed in the container of the water absorbing member. It is also good.

  Furthermore, in the siphon water delivery apparatus according to the present invention, the water delivery apparatus is disposed in a water absorption part different from a water intake part where the water absorption port of the water delivery hose exerting a siphon action is disposed. It may be.

  Furthermore, in the siphon water supply apparatus according to the present invention, one of the connections between the water supply apparatus and the water supply hose is provided with a flange provided with a plurality of cutouts that fit into the bolt holes of various flanges, It may be characterized by using a connecting member provided with a hole.

  Furthermore, in the siphon water supplying apparatus according to the present invention, the air pushing member is delivered into the water feeding hose and delivers at least one air pushing member or air pushing member to push out the residual air in the water feeding hose. A part may be provided. The water feeding capacity can be enhanced by providing at least one or more air pushing members inserted into the water feeding hose to push out the residual air in the water feeding hose, or by providing an air pushing member delivery part. That is, when laying the water hose on a large uneven ground, it is impossible to make the piping slope constant, and since piping is performed according to the topography of the terrain, the phenomenon that air remains at high piping positions occurs Do. In this case, the air is compressed by the water pressure to narrow the water flow section of the water supply hose, which causes the water supply amount to decrease. In order to discharge this residual air from the discharge port on the downstream side, by pushing the air push-out member downstream with the water pressure of the water supply hose, the inside of the water supply hose on the upstream side through which the air push-out member passes becomes full. The downstream side receives the residual air and pushes it in the downstream direction while storing it, and finally the air is discharged from the discharge port so that the water flows in the inner cross section of the water hose with a full or near full cross section. The amount of water supply can be increased.

  Furthermore, in the siphon water supply apparatus according to the present invention, the air pushing member is larger than the inner cross section of the water supply hose before being inserted or delivered into the water supply hose, and the air pushing member delivery portion, the water injection merging member or the It may be characterized by having a cross-sectional shape which is the same as or slightly smaller than the inner cross section of the water supply hose when it is inserted or delivered anywhere in the water supply hose.

  Furthermore, in the siphon water delivery apparatus according to the present invention, the water delivery hose or the water injection joining member is provided with a holding member for holding the air delivery member. It may be something. By adopting such a configuration, the air pushing member can be delivered at any time.

  Furthermore, in the siphon water supply apparatus according to the present invention, the water supply hose is at least a part of which is made of a flexible water supply hose having one or more members, and is connected between the water supply device and the water supply joining member It may be characterized by being provided. By adopting such a configuration, after water supply from the water supply device is stopped, the water supply hose is pushed by the atmospheric pressure and contracted to close the water passage portion, and the air pushing member is disposed in the flexible water supply hose. And is pushed downstream by water pressure from the water supply equipment, and after the water supply from the water supply equipment is stopped, the water supply hose is pushed to atmospheric pressure and contracted to close the water supply part. It may be Due to this phenomenon, when the water supply equipment is stopped normally, the water in the water supply hose flows back to the water supply equipment side. The problem that emergency stop could not be performed and the backflowed water gives impact to the water supply equipment. It is possible to solve the linked water hammer phenomenon.

  Furthermore, in the siphon water supply apparatus according to the present invention, when the air pushing member is delivered, the diameter of the water supply port of the water supply device is equal to or less than the diameter of the water supply hose supplying water downstream or the water supply hose and the water supply hose on the siphon water absorption side. May be When starting the water supply operation using the air extrusion member, even if the caliber of the water supply equipment is smaller than the caliber of the water supply hose, if it has the ability to pump up to the required lifting capacity of the water equipment, behind the air extrusion member Since the water pressure generated by the accumulated and flowing water gradually increases, the air pushing member can be slowly but surely pushed in the direction of the downstream discharge port. As a result, the air remaining in the water supply hose on the downstream side of the air extrusion member is sequentially pushed and moved in the discharge port direction with the movement of the air extrusion member, and is expelled from the discharge port in due course. It will flow down as it approaches full capacity. When the head is 7 m or less, stopping the water supply equipment at this time starts water absorption from the siphon water absorption hose side of the water supply hose larger than the diameter of the water supply equipment, drains to the discharge port on the downstream side of the water supply hose, and the siphon action starts It will be. In addition, if the lift is 7 m or less, the water level in the spring section will decrease by continuing to operate the siphon, and if the lift becomes 7 m or more, the water supply operation will be sustained by using the water supply equipment together. .

Further, in the siphon device according to the present embodiment, the first opening portion is provided with a first water supply hose disposed in the spring portion for absorbing water in the siphon portion,
A water absorption member for sand removal is provided at the tip of the first water supply hose,
The water absorption member for sand discharge comprises a main water absorption portion for absorbing water and soil together and an auxiliary water absorption portion for absorbing only water.
When the water absorption port of the main water absorption part is buried in sand and absorbs a large amount of soil, the fluid having lost fluidity is prevented from stopping the siphon function by clogging in the first water supply hose, the main Water absorbed from the secondary water absorption part is added to the soil taken in from the water absorption part and mixed, and the ratio of the absorbed soil is reduced to improve fluidity, thereby preventing the inside of the water supply hose from being clogged with the earth and sand It may be characterized as possible.

  Furthermore, in the siphon device according to the present embodiment, the auxiliary water absorption unit may include an auxiliary water absorption unit extension member for disposing the water supply unit at a remote unit.

  Furthermore, the present invention provides a water supply method using the above-described delivery device.

  Furthermore, the present invention is used in a method for preventing a break of a bank body due to a rise of water in a reservoir such as a reservoir due to heavy rain or the like in the siphon water supply method using the siphon device described above. When the approach such as a typhoon is expected, it is characterized by increasing the amount of water accepted by the reservoir in heavy rain and preventing the break of the levee body by lowering the water level of the reservoir using the siphon water supply system. Provide a siphon water supply method for spring ponds such as ponds.

  The water supply method of such a siphon apparatus has a feature that the siphon water supply apparatus is used as a maintenance method of a reservoir. Taking the conventional management method of the reservoir as an example, the structure of the reservoir forms the reservoir by blocking the water flowing into the reservoir by the levee to form the reservoir, and the vertical reservoir and the bottom are used to manage the accumulated water. A weir is provided, and at the same time, a high water spout and a high water spouting channel are provided at a position lower than the top end of the embankment at a part of the dam body. The vertical weir is provided with a hole for draining water in order to store and drain water at any height, and an on-off valve or plug is provided for opening and closing this hole (hereinafter referred to as Called).

  The management of the reservoir can select the water level of the reservoir only in stepwise height units, but in order to adjust it to any height, this on-off valve is operated, but at the timing when the water level goes up and down Since it was necessary to continue to operate the on-off valve, which was provided in stages each time, until the water level reached an arbitrary height, several people had to stick to the spring water reservoir all the time. In areas where agricultural water is scarce, there is a custom to always store water as much as possible in a reservoir and fill it with water. For this reason, when the water level reached high water level due to the increase of rainfall, only the excess water was drained from that part to keep the water level constant.

  By draining a large amount of water flowing into the reservoir in the range of the size of the cross section of the high water discharge, it is good as long as the water level of the reservoir can be kept constant, but if unexpected heavy rain occurs, it will flow once Because it can not accept water (water temporarily flowing in a large amount), it will also overflow from high water discharge. This water scours the levee, which leads to the destruction of the reservoir.

  Even if you try to open the on-off valve of the vertical weir, it can not be opened because it is out of reach, or it can not be opened due to aging or breakdown, etc. The issue was that the cost of electricity would be enormous.

  Then, in order to solve the problem of consumption of this huge fuel consumption and electricity cost, although the siphon type drainage device was devised, the conventional siphon drainage device is installed across the dike with the drainage pipe, and the composition is drainage A water inlet is provided at the water intake at the upstream end of the pipe, the outlet at the downstream end, and the pipe top of the drainage pipe. After closing the on-off valve provided on the water inlet and outlet of the siphon drainage device, 2. 2. From the water injection port provided at the top of the drainage pipe, use a submersible pump or the like to fill the drainage pipe with water. Close the opening of the water injection port when it becomes full of water, 4. The siphon action was activated when the opening and closing valves of the water inlet and the outlet were then opened. However, in order to operate the on-off valve provided on the water absorption port or the discharge port, a person must approach to that position, and especially since the water absorption port is installed in the water, it is dangerous that people may lean on it. It was difficult. Also, the work of installing a water supply hose or the like extending from the submersible pump to the water injection port at the top of the pipe required a large number of people.

  Since the siphon drainage device of the present application does not have an open / close valve at the water intake port and the discharge port, no operation by these persons is required. Also, since water injection into the drainage pipe is carried out by installing the water injection joining member at any position on the upstream side including the pipe top, the drainage pipe will flow fully filled with the operation just turning on the submersible pump, Subsequently, it was possible to easily start the siphon action by turning off the submersible pump. It is possible to lower the water level of the reservoir by activating the siphon action just by switching on and off one worker without requiring a large number of people.

  In addition, the siphon action can be adjusted by lowering the water level of the reservoir to the height of the outlet by drainage work by setting the outlet at an arbitrary position if the height is below the reservoir water level. The The characteristics of this siphon action make it possible to keep the water level below the arbitrary level of the spring reservoir and keep it constant, but since the siphon drainage pipe is full of water in that state, the spring reservoir rises in water level due to the inflow of water If the siphon function is activated again to start drainage, the water level has been lowered to an arbitrary height and it has a feature that makes it possible to keep it at a constant height again. As a result, by lowering the water level to an arbitrary height in advance when heavy rainfall is expected, the amount of acceptance will increase, and it is possible to safely receive a typhoon.

  Embodiments of the siphon water delivery apparatus 100 and the water delivery method using the siphon delivery apparatus 100 according to the present invention will be described in detail based on the drawings. Note that the embodiments and drawings described below exemplify a part of the embodiments of the present invention, and are not used for the purpose of limiting to these configurations. In the first embodiment, the siphon water delivery apparatus 100 is capable of switching between a lift height of 7 m or less and a lift height of 7 m or less in the first embodiment. Since the function is the same as that in either case, the description of the first embodiment will replace the description of each siphon water delivery device 100.

First Embodiment
The siphon water supply apparatus 100 concerning 1st Embodiment is shown by FIG. FIG. 1 is a diagram schematically showing the configuration of the siphon water delivery apparatus 100 according to the first embodiment. The siphon water delivery apparatus 100 according to the first embodiment mainly includes a water delivery hose 10, and a water delivery apparatus 20 for supplying water for preventing evaporation due to a negative pressure generated at the pipe top 10b of the water delivery hose 10. ing. As the water supply hose 10, a hard hose which does not easily deform its cross-sectional shape is used. Examples of the hose using a hard material include a suction hose generally referred to and hoses such as hard polyethylene and vinyl chloride.

  In the siphon water supply apparatus 100 according to the first embodiment, the water supply apparatus 20 is disposed in the upstream or high water area, such as a pool, a pond, a swamp, a river, etc. In order to exert the siphon effect, the water reservoir 90 is installed at a position lower than the water level 90a. The water supply hose 10 is not provided with the opening / closing device at the discharge port 10a and is always in the open state.

  Next, the function of the siphon water delivery apparatus 100 according to the present invention will be described. As shown in FIG. 2A, the water supply apparatus 20 is disposed on the side of the spring part 90, the water supply hose 10 is installed over the obstacle 1, and the discharge port 10a is the position of the water supply apparatus water inlet 20a of the water supply apparatus 20. It is disposed on the opposite side of the spring portion 90 across the obstacle 1 at a position lower than the water level of the slightly higher water level 90a. The water level in the spring 90 fluctuates between 90b, 90c and 90d. The water level 90 d represents the highest water level at the top end of the wall of the spring portion 90 which is the obstacle 1. When the water supply equipment 20 is operated to inject water into the water supply hose 10 and the water in the water supply hose 10 is full of water and water starts to flow from the discharge port 10a, the power supply of the water supply equipment 20 is stopped and water supply by the water supply equipment 20 is stopped. As a result of this operation, the water in the water spray unit 90 is sucked into the water feeding device 20 from the water feeding device suction port 20a of the water feeding device 20, passes through the water feeding hose 10, and moves to the discharge port 10a. The water supply work by so-called siphon will be started. However, since a lift of 7 m has conventionally been considered as the limit to the siphon action, there is a history of using a water supply plan within that range. As shown in FIG. 2B, since the water level difference is about 7 m from the water level 90c to the water level 90d, it has been considered that the siphon action does not work unless the water level is between these levels. The reason why 7 m has been considered as the limit of the lift is that if the water level of the spring section 90 continues to decrease due to the siphon water supply operation, the lift will gradually increase and approach 7 m. When the water level exceeds 90m, for example, when the water level reaches 90d, a vaporization phenomenon occurs with the negative pressure phenomenon in the water supply hose 10 near the pipe top 10b, the pipe top 10b becomes hollow and water breaks up in the water supply hose 10 and stops flowing Happens. For this reason, a lift of about 7 m has been considered as the limit value in water supply operation by siphon.

On the other hand, the present inventors succeeded in greatly improving the problem of the critical height of the lift in the siphon water delivery apparatus 100. As described above, the evaporation phenomenon by negative pressure occurs in the tube top 10b, and it is hollowed to divide the water, and even if water supply is stopped apparently, as shown in FIG. 2B, siphon water action is likely to occur. Energy, that is, the negative pressure energy of the cavity 10c, and the potential energy of water which is about to flow down to the outlet 10a by the gravity of the water downstream of the cavity 10c in the water supply hose 10, and the atmospheric pressure The water of the part 90 is stored in the water supply hose 10 as energy to be sucked into the water supply hose 10 from the water supply apparatus water intake 20a of the water supply apparatus 20. In this state, the water supply apparatus 20 is in a state where the balance of the energy which is cavitation by the energy that the water divided by the negative pressure tends to flow down at the tube top 10b and the energy that stops the flow of water is kept balanced. By pushing up the water by the water supply energy, the balance to maintain balance is broken and the cavity 10c disappears and the water hose 10 is connected with water, temporarily lowering the water level of the water supply unit 90 and limiting the siphon It was confirmed by experiments that the siphon action and the water feeding operation of the water feeding apparatus 20 continue to work even if the head is over 7 m, for example, the head becomes 20 m or more. That is, as shown in FIG. 1, it has been found that the combination of the siphon water supply function and the water supply function of the water supply device 20 greatly exceeds the numerical value of the critical lift and drainage of the siphon alone or the water supply device alone. For example, when KRS 2-8S (made by Tsurumi Seisakusho Co., Ltd.) is used as the water supply device 20, the drainage amount of the manufacturer's published value is 0 m ³ / min at a lifting head of 18 m which is the limit. It is 1.2m ³ / min at 16m lift, but the result of measuring the actual drainage volume using only the water supply equipment by the experiment is 0.44m ³ / min at a lift height of 16m, which is significantly lower than this manufacturer's published value It was only drainage volume (D in FIG. 24). As a matter of course, it is impossible to start the siphon because it is not possible to flow the inside of the water supply hose 10 in a full water state with this amount of drainage. In this same piping situation, the siphon action is activated using an air extrusion member described later, and combined with the water supply by the water supply device 20, it is confirmed that the water supply capacity measures 3.9 m ³ / min of water supply, It was confirmed that even if it reached 20 m, the drainage capacity was 2.5 m ³ / min, and it exhibited a water delivery function that could not be achieved with only the water delivery equipment 20 alone or only the siphon alone technology (see FIGS. 24 to 26). . That is, not only the siphon function is improved by the water supply that combines the water supply apparatus 20 and the siphon action, but the function of the water supply apparatus 20 is also improved by the water supply function of the siphon. This is because water supply equipment for wastewater are announced manufacturers is 1.2 m ³ / min at lift 16m, published wastewater 1.2 m ³ of lift wastewater was confirmed by experiments 16m 3.9m ³ / min from the water supply device 20 This is because the remaining 2.7 m ³ / min is considered to be the water supply amount by siphon excluding / min. In addition, during the water supply operation, the current applied to the water supply device 20 was continuously measured. As a result, even if the water supply phenomenon by the siphons is combined using the water supply hose 10, the phenomenon of the over current does not occur in the water supply apparatus 20. In other words, it was also confirmed that the water supply equipment 20 could continue to operate within the stable function range. With these operations, water supply by water supply equipment 20 is used in combination as auxiliary water supply energy where synergy effect with siphon water supply for sustaining the siphon function by water supply of water supply equipment 20 appears, hollow part 10c in water hose top 10b It was found that the siphon action continued by preventing it from occurring.

  The water delivery device 20 becomes incapable of water delivery when it becomes larger than the manufacturer's announced limit lift height, and in the case of the siphon also stops when it exceeds the limit lift 7 m. However, when the water feeding device 20 is added to the siphon as in the present technology and used in combination, the hollow portion generated in the pipe top portion 10 b of the siphon action is filled with water by the water feeding device 20. Become. By this action, a cavity due to the vaporization phenomenon is not generated in the siphon action, and the siphon action is sustained. When a drainage plan is to be made by the siphon water supply apparatus 100 developed this time, the method of starting is divided into two types according to the height of the water level at the start of the drainage work. That is, 1. If the water level of the spring 90 is low and it exceeds the top end of a natural dam etc., if the water discharge amount of the water transmission device 20 is too low to activate the siphon action, the air extrusion member 50 As described above, the flow rate in the water supply hose 10 is filled with water and the siphon action and water supply by the water supply device 20 are used in combination to carry out drainage work as described above. Drainage work more than function is possible. Also, 2. When the water level of the spring 90 is high and the head is 7 m or less, the water feeding device 20 is activated and the air pushing member 50 is sent out into the water feeding hose 10, and the water feeding device 20 is stopped when the water feeding hose 10 starts flowing down. By switching to only siphon work and operating the drainage work, fuel consumption and maintenance costs can be significantly reduced. In any of cases 1 and 2, it is preferable to use a water injection merging member 30 described later, which enables water supply by the water supply apparatus 20 and siphon water supply to be switched or used together only by the power supply of the water supply apparatus 20. Moreover, the conventional drainage limit is achieved by using the air pushing member 50 for pushing out the residual air, which narrows the water flow cross section in the water supply hose 10, to the discharge port 10a and using the siphon action and the function of the conventional water supply equipment 20 in combination. It is possible to provide the siphon water delivery system 100 in which the lift and the displacement are greatly improved.

  The siphon water delivery apparatus 100 produced as mentioned above is started as follows. The siphon water delivery apparatus 100 concerning 1st Embodiment uses the water delivery apparatus 20 provided with the water delivery quantity which pushes out the air in the water delivery hose 10 at a stretch. Preferably, the water supply diameter of the water supply device 20 is larger than the diameter of the water supply hose 10. Then, the water supply device 20 vigorously pours water into the water supply hose 10 and flows down to the low area side. If this state is continued for a while, the residual air in the water supply hose 10 is discharged from the discharge port 10a while the water is discharged from the discharge port 10a, so that the water in the water supply hose 10 is kept full of water. Ru. At first, the water spouted from the discharge port 10a mixes with the air and the white water is discharged, but when the air in the water supply hose 10 is discharged and becomes full of water, it changes to transparent water. Then, the siphon action in which water flows in automatically in the water supply hose 10 will start starting. Then, when air or the like in the water supply hose 10 is completely discharged from the discharge port 10a, water is supplied between the water in the high water area 90 and the discharge port 10a of the water supply hose 10 installed in the low area. The inside of the hose 10 is full of water, and the operation state of the siphon action is completely maintained.

  According to the siphon water delivery apparatus 100 configured as described above, if the head is 7 m or less, if the water is able to be drained from the high water reservoir 90 to the low area by the siphon action once it is ready. After that, the water of the spring portion 90 can be continuously sent to the discharge port 10a by the siphon action without requiring power. Even when the lifting head exceeds 7 m, water supply can be maintained by using the water supply device 20 in combination.

  According to the above siphon water supply apparatus 100, it is possible to have both the water supply function by the water supply device 20 and the water supply function by the siphon. By using such a siphon water delivery apparatus 100, even if the water delivery apparatus 20 having the same function is used, the siphon drainage operation and energy are combined, and the synergetic effect increases the amount of drainage, and the head also greatly exceeds the limit head. Water supply work can be done. That is, both the siphon function and the water supply function of the water supply apparatus 20 can be improved.

Second Embodiment
The siphon water delivery apparatus 100 concerning 2nd Embodiment is shown by FIG. FIG. 3: is a side view which shows the outline of a structure of siphon water supply apparatus 100 concerning 2nd Embodiment. The siphon water supply apparatus 100 according to the second embodiment mainly includes a water supply hose 10 and a water injection merging member 30 provided in the middle of the water supply hose 10. The water supply hose 10 is provided with a first water supply hose 11 whose tip is opened and which sucks water by the function of the siphon, a second water supply hose 12 connected with the water supply device 20, and a third water supply hose 13 having a discharge port 10a. ing. The first water supply hose 11 and the second water supply hose 12 connected to the water supply device 20 at the tip are disposed in the water supply unit 90, and the discharge port 10 a of the water supply hose 10 of the third water supply hose 13 is the water surface of the water supply unit 90 It is located on the outside of the dike, which is the obstacle 1 at a lower position.

  As shown in FIG. 4, the water injection merging member 30 has a first opening 31, a second opening 32, and a third opening connected to the first water hose 11, the second water hose 12, and the third water hose 13, respectively. And a unit 33. The water injection merging member 30 is formed in a substantially Y shape such that the water channel of the first opening 31 and the second opening 32 has an acute angle. The end of each opening (31 to 33) of the water injection merging member 30 is provided with a connecting function, for example, a flange or the like, and can be easily and firmly connected to the water supply hose 10.

  A switching valve 35 is provided inside the junction of the first opening 31 and the second opening 32. The structure of the switching valve 35 provided at the junction prevents the flow of water from the first opening 31 side from flowing into the second opening 32 side, and the flow from the second opening 32 side is the first This has the effect of preventing the flow into the opening 31 side. In particular, when the extension of the water supply hose 10 to the downstream side connected to the third opening 33 is long or when the water supply hose 10 is bent and a resistance occurs in the flow, the flow may stagnate due to the resistance. At the same time as water is generated to flow to another route, this can be prevented and water can flow to the downstream discharge port 10a. Further, when water is supplied by using the functions of both the siphon and the water supply device 20, the switching valve 35 holds the opening area at a ratio corresponding to the flow rate at the middle of both at the junction.

  In the switching valve 35, as shown in FIG. 5, the switching valve 35 for switching the direction of the flow provided inside is pushed and moved by the flow, so that switching is performed so that either one of the flow paths is not fully opened. A switching valve movement stop member 35b may be provided for stopping the movement of the switching valve 35 in the middle of the movement range of the valve. The switching valve movement prevention member 35b is formed by projecting a bolt in the water injection merging member 30 so as to abut on the switching valve 35, and by providing and placing at a plurality of places, adjusting the projection condition of the bolt The movement restraining position of the switching valve 35 can be adjusted.

  Regarding the method of switching the inflow of water from the first opening 31 or the second opening 32, the following method may be considered other than the switching valve 35 described above.

  (1) For example, as shown in FIG. 6, an opening check valve 35a having an opening / closing function may be separately provided at the end of the first opening 31 and the second opening 32. By opening and closing the opening check valve 35 a, the flow of water from the second opening 32 is prevented from flowing in the direction of the first opening 31 and is allowed to flow in the direction of the third opening 33. When the water supply device 20 is stopped when the inside becomes full of water, the flow can be changed to the flow of the siphon from the first opening 31.

  (2) Moreover, as shown to FIG. 7A, you may arrange | position one or more flexible water supply hoses 25, such as a sunny hose, between the water supply apparatus 20 and the 2nd opening part 32. As shown in FIG. Thus, in the case of one hose, when the water injection into the water supply hose 10 is completed by the water supply device 20 and the water supply device 20 is stopped, the flexible water supply hose 25 is pushed by the atmospheric pressure and the movement of water in the water supply hose 25 Because water is not allowed to pass through, water does not flow either to the side of the second water supply hose 12 connected to the water supply apparatus 20 or to the side of the water supply hose 10 connected to the downstream side of the discharge port 10a. However, since the energy in the water in the water supply hose 10 tends to move in the direction of the discharge port is present, the siphon water absorption action is performed on the side of the first water supply hose 11 capable of water flow, which is not blocked by this. It will work. In addition, when two or more flexible water hoses 25 are continuously arranged, as shown in FIG. 7B, connection is completed when the water feeding device 20 completes the water injection into the water feeding hose 10 and the water feeding device 20 is stopped. Even if the connection between the two or more flexible water supply hoses 25 is cut off, the other part of the flexible water supply hose 25 is cut off by the atmospheric pressure and the movement of the water in the water supply hose 25 to decouple the air. Since it does not pass through, it can be separated in a state in which one does not enter the second water supply hose 12 side connected to the water supply equipment 20 and the other does not enter the water supply hose 10 connected to the downstream side discharge port side. By arranging the flexible water supply hose 25 in this manner, as shown in FIG. 8, when the water supply of the water supply device 20 is stopped, the pressure difference between the negative water pressure inside the flexible water supply hose 25 and the external air pressure The cross section of the flexible water supply hose 25 can be deflated and closed. Thereby, the flow can be changed from the second opening 32 side to the first opening 31 side.

  Further, as a variation of the arrangement of the water injection merging member 30, as shown in FIG. 9A, the water injection merging member 30 may be directly connected to the water feeding device 20. By directly attaching the water injection joining member 30 to the water feeding device 20, the first water feeding hose 11 on the siphon side is also dipped in water when the water feeding device 20 is immersed in the water of the spring portion 90, so the first siphon side The possibility of the air remaining in the water supply hose 11 can be reduced. Therefore, when the water supply of priming water into the third water supply hose 13 in the water supply apparatus 20 is stopped, the process of pulling the air in the first water supply hose 11 on the siphon side with the energy of the priming water can be omitted.

  Furthermore, as shown to FIG. 9B, the 1st water supply hose 11 may not be connected with the 1st opening part 31 used as the siphon water absorption side of the water injection joining member 30. As shown in FIG. Since the first water supply hose 11 on the siphon side is not connected to the first opening 31 of the water injection merging member 30 in the same manner as described above, when the water supplying apparatus 20 is immersed in the water of the water injection section 90 Similarly, since it is immersed in water, when the water supply apparatus 20 is stopped, the water in the spring portion 90 starts to be sucked from the first opening 31 of the water injection merging member 30 by the siphon action and the siphon action starts. The process of discharging the air in the first water supply hose 11 to the downstream portion can be omitted. In the water injection joining member 30 for joining the second water supply hose 12 on the water supply device 20 side and the water absorption port 11 a on the siphon side, the water absorption port 11 a on the siphon side is positioned below the second water supply hose 12 on the water supply equipment side. By arranging, it is effective in preventing that the earth and sand etc. which flowed in the water supply port by the side of a siphon in the siphon water supply work flow in into the 2nd water supply hose 12 by the side of water supply equipment.

  The installation method and usage method of the siphon water delivery apparatus 100 configured as described above will be described with reference to FIG. 3. First, with the water injection merging member 30 installed at any position of the full extension of the water supply hose 10, the water absorption port 11a of the first water supply hose 11 is disposed in the water filling portion 90, and the tip of the second water supply hose 12 The water supply apparatus 20 connected to is similarly disposed in the spring portion 90. The third water supply hose 13 is disposed at a position where the discharge port 10 a is lower than the water surface of the spring portion 90.

  Next, the starting method of the siphon water supply apparatus 100 concerning 2nd Embodiment is demonstrated. The siphon water delivery apparatus 100 concerning 2nd Embodiment uses the water delivery apparatus 20 provided with the water delivery quantity which pushes out the air in the water delivery hose 10 at a stretch. Preferably, the water supply diameter of the water supply device 20 is larger than the diameter of the water supply hose 10. Then, water is injected to the second opening 32 of the water injection merging member 30 by the water supply device 20. Then, the water is vigorously injected into the third water supply hose 13 via the water injection merging member 30, and flows down to the low area side. When this state is continued for a while, the residual water in the water supply hose 10 is discharged together with the water from the discharge port 10a, and the water supply hose 10 maintains the full water state while the water flows. At first, the water spouted from the discharge port 10a mixes with the air and the white water is discharged, but when the water supply hose 10 is full of water, it changes to transparent water. If this state is confirmed, the water supply apparatus 20 is stopped and the water injection to the third water supply hose 13 is stopped. Even if water injection stops, water will continue to be drawn by the attraction of the earth from the constantly open outlet 10a in the low area on the downstream side, so full water in the water hose 10 will be discharged by potential energy. The action of flowing out to 10a works. With the phenomenon that the air in the first water supply hose 11 is drawn to the downstream side due to the action of flowing to the downstream side, the water is supplied from the water intake port 11a disposed in the spring section 90 of the high water level area. 11, water is drawn into the water supply hose 10, and when the air etc. in the water supply hose 10 is completely discharged from the discharge port 10a, the water in the high water area 90 and the water provided in the low area The inside of the water supply hose 10 between the discharge port 10 a of the hose 10 is full and the siphon action is completely maintained. In addition, when the water supply apparatus 20 of the aperture diameter larger than the aperture diameter of the water supply hose 10 is used, as shown in FIG. 17, the flow is divided into multiple and each water injection joining member 30 connected with the multiple water supply hoses 10 Water can be supplied by connecting to the second opening 32 to which the second water supply hose 12 from the water supply device 20 is connected, and the plurality of siphon water supply devices 100 can be simultaneously activated or operated.

  According to the siphon water supply apparatus 100 configured as described above, if the head difference is within 7 m, once the water is ready to drain from the high water reservoir 90 by the siphon action, After that, the water of the spring portion 90 can be continued to flow to the low area by the siphon action without requiring power. In addition, even when the lift is 7 m or more, the water feeding device used for the siphon drainage operation can be used as it is, and can be switched to the operation by using in combination with the water feeding device 20.

  According to the siphon water supply apparatus 100 according to the second embodiment, unlike the first embodiment, the problem of fuel consumption which is indispensable for the operation of the water supply apparatus 20 which could not be solved in the first embodiment, the small water supply apparatus 20 The problem of the maintenance of the refuse removal which is clogged to water supply equipment water absorption mouth 20a is solved. That is, since the siphon water absorption port 11a is different from the water supply apparatus water absorption port 20a of the water supply apparatus 20 and has a large bore and no obstacle such as an on-off valve, the wastes clogged in the small water supply apparatus water absorption port 20a of the water supply apparatus 20 Since the water is sucked into the water supply hose 10 and discharged to the discharge port 10a on the downstream side, the clogging of the dust is prevented and the removing operation becomes unnecessary. Since the water intake 11a of the first water supply hose 11 is provided, the flow of siphons passing through the water supply apparatus 20 as the passage route is greatly reduced. As a result, the flow of the siphon backs up the rotation of the motor of the water supply device, whereby the load on the motor acting on the water supply can be reduced to thereby further prevent the occurrence of the over current.

Third Embodiment
The siphon water supply apparatus 100 concerning 3rd Embodiment is shown by FIG. The third embodiment is characterized in that the water feeding device suction port 20a of the water feeding device 20 is disposed not at the water suction portion 90 on the siphon water absorption side but at another water absorption site 90B. The function may or may not reach the spring section 90. These will be separately described below. In the third embodiment, the first opening 31 and the third opening 33 a are provided in the first opening 31 and the third opening 33 of the water injection merging member, respectively.

  First, the case where the lift function of the water supply device 20 does not reach the spring portion 90 will be described. As shown in FIG. 10B, the water injected from the second opening 32 is supplied to the first water supply hose 11 on the siphon water absorption side through the first opening 31 and the function of the water supply apparatus 20 functions in the first water supply hose 11 to the siphon side. Fill the water. However, due to the ability of the water supply device 20, the spring portion 90 can not be reached. In this state, the first opening / closing member 31a is closed to store the water in the first water supply hose 11, and at the same time, the third opening / closing member 33a is opened, as shown in FIG. 10C. Water is supplied into the water supply hose 10 below the opening / closing member 31 for the opening. As shown in FIG. 10D, the water in the water supply hose 11 on the siphon water absorption side is stopped by opening the first opening opening / closing member 31a when the water supply apparatus 20 is stopped when the water supply hose 10 is filled with water. It will act as a priming water to suck in the water of the upstream side of the spring section 90. This operation is particularly effective when the extension of the third water supply hose 13 connected to the third opening 33 is not twice as long as the extension of the first water supply hose 11 connected to the first opening 31. Demonstrate. That is, since the state in which the third water supply hose 13 is filled with water is extended into the first water supply hose 11, the extension of the third water supply hose 13 is twice or more the extension of the siphon water absorption hose 11. If not, the same effect as extending the extension of the water supply hose 10 can be obtained.

  Next, the case where the lift function of the water supply device 20 reaches the spring part 90 will be described. As shown in FIG. 10B, the water injection merging member 30 bypasses the water injection merging member 30 in a state in which the third opening / closing member 33a of the third opening 33 is closed from the water feeding device 20 through the first water hose 11 for siphon. Water is sent to the spring section 90. In this case, the first opening opening / closing member 31 a of the first opening 31 is not provided or is open. When the water supply reaches the spring part 90 with the inside of the first water supply hose 11 for the siphon filled with water, the third opening / closing member 33a is opened to change the water supply direction from the water supply apparatus 20 to the third water supply hose 13. In this case, since the first water supply hose 11 for the siphon is full of water, the siphon action works and the water in the spring portion 90 flowing in the first water supply hose 11 for the siphon is supplied from the water supply device 20 by the water injection joining member 30. The water from the spring section 90 is supplied to the first water supply for siphon by stopping the water supply device 20 when the third water supply hose 13 flows to the third water supply hose 13 and the third water supply hose 13 flows in a full water state. The siphon water supply operation will be activated through the hose 11 and the third water supply hose 13. With this structure, the siphon action can be activated even when the water injection joining member 30 is disposed on the downstream side of the lift pipe top. When priority is given to the water supply amount over the fuel cost, siphon drainage work in combination with the water supply device 20 can be performed as shown in FIG. 10E. Also, when the arrangement position of the water injection merging member 30 is provided at a position lower than the water level of the spring portion 90, a flexible hose may be used instead of the third water supply hose 13 connected to the third opening 33. . Water flowing by siphon action in the first water supply hose 11 from the spring portion 90 to the first opening 31 flows into the flexible hose 25 through the third opening 33, and the drainage operation is sustained . In addition, when the arrangement position of the water injection merging member 30 is provided at a position higher than the water level of the spring portion 90, as shown in FIG. 10E, the water supply device 20 continues to operate after the siphon activation. The synergetic effect of the water supply apparatus 20 is exhibited, and the characteristic that the amount of drainage becomes large is exhibited.

Fourth Embodiment
The fourth embodiment is a technique for discharging residual air in the water supply hose 10 to fill the water supply hose 10 as much as possible, and the first embodiment, second embodiment or third embodiment described above is used. It is a technology used in combination with the form.

  The fourth embodiment is to prevent damage such as crushing or cracking of the water supply hoses 10 and 11 due to the atmospheric pressure which is an external pressure in addition to the negative pressure phenomenon in the water supply hoses 10 and 11 by the siphon action. It is a means. The embodiment of FIGS. 10A and 10D of FIG. 10 will be described by way of example. Collapse and cracking of the first water supply hose 11 and the third water supply hose 13 caused by the atmospheric pressure which is the external pressure in addition to the negative pressure generated in the first water supply hose 11 and the third water supply hose 13 after the siphon action is activated. In order to prevent damage such as, etc., it is connected to the first water supply hose 11 and the third water supply hose 13 at a position lower than the water level of the spring 90 on the downstream side of the pipe top 10b of the siphon water supply device 100 to control the evaporation amount adjustment valve 40 Connect Preventing damage such as crushing or cracking of the first water supply hose 11 and the third water supply hose 13 by adjusting the generation amount of the vaporization phenomenon caused by the negative pressure generated in the first water supply hose 11 and the third water supply hose 13 Can. In the case where the installation angle of the water supply hose on the downstream side of the pipe top 10b is steep, the flow is particularly oblique flow, and only the bottom portion of the inner cross section of the first water supply hose 11 and the third water supply hose 13 flows. The part other than water is a gas in which water is vaporized by negative pressure. That is, since the atmospheric pressure which is the external pressure is added to this, the water flow section is clogged so that the water flow section is blocked or a crack is generated and air is sucked into the first water hose 11 and the third water hose 13 to stop the siphon phenomenon. It becomes. The water blocking hose of the siphon water delivery apparatus 100 is made gradually larger than the cross section layer of the vaporized gas which occupies the upper part of the cross section of the first water delivery hose 11 and the third water delivery hose 13 A part of the water flowing through the bottom of the valve can be temporarily retained upstream of the evaporation amount adjusting valve 40. Thus, the amount of stagnation is gradually increased from the evaporation amount adjustment valve 40 to the pipe top portion 10b on the upstream side so that the insides of the first water hose 11 and the third water hose 13 flow fully filled up to the pipe top 10b. . As a result, the occurrence of oblique flow can be prevented and the vaporization phenomenon can be almost eliminated. By eliminating the gas vaporized in the first water supply hose 11 and the third water supply hose 13 and making the entire cross section a flow of water, the influence of the external pressure of the atmospheric pressure is reduced and the first water supply hose 11 and the third water supply hose 13 Can prevent damage. The purpose of the evaporation amount adjustment valve 40 is not the switching device for flow adjustment generally said, but the mixed flow phenomenon generated in the steep first water hose 11 and the third water hose 13 flows at the bottom but the flow velocity Since the evaporation amount adjusting valve 40 blocks two or more thirds of the top of the water passage of the water hose 10, it only blocks the layer of the gas portion and does not affect the overall flow rate so much. As the control valve of evaporation amount control valve 40 is lowered and the control valve is made to reach the bottom of water supply hose 10 at a part of the upper part of the flow and a part of the flowing water is stagnated, water is discharged from the discharge port of the drainage hose It is a major feature that the flow rate to be achieved is a large volume flow rate which is almost the same as a state in which the inner cross section of the gentle slope water hose 10 is filled with water.

  That is, a diagonal flow occurs in the water hose 10 laid on a steep slope. A part of water flowing through the inner cross section of the evaporation amount adjustment valve 40 of the siphon water delivery apparatus 100 is adjusted by narrowing the gas portion from the upper part of the inner cross section of the first water hose 11 and the third water hose 13 When it is made to temporarily stay temporarily between the valve 40 and the lift pipe top 10b on the upstream side and its retention amount is gradually increased, it reaches the lift pipe top 10b soon and the insides of the first water supply hose 11 and the third water supply hose 13 It will flow when it is full. This makes it possible to almost eliminate the oblique flow and the vaporization phenomenon. By making the entire cross section in the first water supply hose 11 and the third water supply hose 13 be a flow of full water, the influence of atmospheric pressure can be prevented. This can prevent damage to the water supply hose 10 due to the effects of negative pressure and atmospheric pressure. The evaporation amount adjustment valve 40 is not a switching device generally referred to for controlling the flow rate, and water discharge from the discharge port 10a of the third water supply hose 13 even if the water passage cross section is blocked by two thirds or more in oblique flow It is characterized in that the flow rate to be obtained is almost the same as the state in which the inner cross section of the evaporation amount adjustment valve 40 is fully opened.

  Further, instead of the above-described valve for adjusting the amount of vaporization, the vaporization adjustment opening and closing device 41 may be employed. A siphon water delivery system 100 using a vaporization adjustment closure 41 is shown in FIG. 11B. FIG. 11A is a siphon device that does not have the vaporization adjustment opening / closing device 41, and is a diagram for comparison. The vaporization adjustment opening / closing device 41 is for preventing evaporation phenomenon due to negative pressure in the third water feeding hose 13 having a drainage function and preventing damage to the third water feeding hose 13. When the vaporization adjustment opening / closing device 41 is not provided, As shown in FIG. 11A, the third water supply hose 13 on the downstream side of the pipe top 10b of the third water supply hose 13 is provided at a position lower than the water level of the spring part 90 on the upstream side. When the piping gradient of the hose 13 is steep and the water head difference between the water level of the spring portion 90 and the discharge port 10a is large, the inside of the third water supply hose 13 is a diagonal flow, that is, concentrated only at the bottom of the cross section of the third water supply hose 13 Flow at a high speed. In this case, the negative pressure phenomenon and the flow vibration generated in the third water supply hose 13 are transmitted to the place where the negative pressure phenomenon of the third water supply hose 13 is occurring, and the third water supply hose 13 starts to vibrate in small steps. Become. If this vibration over a long period of time, the third water supply hose 13 will be dented or damaged and air will enter, which will greatly affect the continuation of the siphon action. On the other hand, as shown in FIG. 11B, the gas section of the inner cross section of the vaporization adjustment opening / closing device 41 of the siphon water delivery apparatus 100 is narrowed from the top of the inner cross section of the first water delivery hose 11 and the third water delivery hose 13. A part of the flowing water is temporarily retained temporarily from the vaporization adjustment opening and closing device 41 to the upstream lift pipe top 10b, and the amount of retention is gradually increased, and eventually reaches the lift pipe top 10b and reaches the first water supply hose The 11 and the 3rd water supply hose 13 come to flow in a full water state. This makes it possible to almost eliminate the oblique flow and the vaporization phenomenon. By making the entire cross section in the first water supply hose 11 and the third water supply hose 13 be a flow of full water, the influence of atmospheric pressure can be prevented. This can prevent damage to the water supply hose 10 due to the effects of negative pressure and atmospheric pressure.

  In particular, the vaporization control opening and closing device 41 according to the present invention may be of the following form. That is, as shown in FIG. 12, a sandwiching portion 41j which encloses the gate portion 41a, and the sliding space 4i of the gate portion 41a and the gate portion 41a vertically and horizontally, and a sandwiching plate sandwiching the gate portion 41a from the upstream and downstream sides A pair of holding plates 41d having a plurality of holes 41g around the water flow holes 41b and the water flow holes 41b and having the flanges 41c formed therein, and vertical movement bolts for moving the gate portion 41a up and down in the holding plates 41d And 41e. With this structure, when connecting with the water supply hose, the hole 41g of the flange 41c provided in the vaporization adjustment opening and closing device 41 and the hole 41g 'provided in the flange member 41f provided at the end of the water supply hose are aligned. Can be fixed firmly with the bolt and nut 41 h. The spindle type opening / closing device is a switching device that rotates the screw and moves the gate (water control plate) provided at the lower end up and down to open and close the water flowing portion of the switching device to adjust the flow rate. The structure of the opening / closing device is a flange portion for connecting to a flange of a pipe such as a water hose which is connected at the upstream portion and the downstream portion in addition to the cover members surrounding the upstream and downstream sides of the gate, upper and lower surfaces, and left and right sides. Had been prepared separately. For this reason, the entire switchgear has a thick structure, is heavy, and transport by manpower and work contents are limited. However, by adopting the vaporization adjustment opening and closing device 41 according to the present invention, it is possible to omit the flange member for pipe connection, which has been separately provided conventionally, and since it has become flat as a whole, it is compactly installed at the time of use It became possible to arrange many pieces even in a narrow place when carrying or storing. Moreover, as a result of achieving weight reduction by this, the range of manual transportation and installation work was expanded.

Fifth Embodiment
The fifth embodiment is a technique for discharging residual air in the water supply hose 10 to fill the water supply hose 10 as much as possible, and the first embodiment, the second embodiment or the third embodiment described above is used. It is a technology used in combination with the form.

  The fifth embodiment is a means for discharging air from the discharge port 10 a using the air pushing member 50 in the water supply hose 10. When the water supply hose 10 is provided, the slope of the water supply hose 10 is unlikely to be laid at a constant level. As shown in FIG. 13, air is placed at a high position of the water supply hose 10 for laying according to the topography. It tends to accumulate. In this case, the residual air H is compressed to corrode the water flow cross section of the water supply hose 10, so that the water supply amount is reduced. According to the present technology, after inserting the residual air H into the water supply hose 10, the air extrusion member 50 having a cross section the same as or slightly smaller than the inner cross section of the water supply hose 10 is pushed downstream by the water pressure generated by the water flow. The residual air in the water supply hose 10 is pushed out from the discharge port 10 a by being pushed to the downstream side in a state where the water 50 is full or nearly full of the inner cross section of the water supply hose 10, and water is used as the inner cross section of the water supply hose 10 It is a means by which it is possible to increase the amount of water supply by filling to flow as close as possible to the full water section. In the siphon water delivery system using an air extrusion member, the bore diameter of the water delivery port of the water delivery equipment can be smaller than the bore diameter of the water delivery hose feeding water downstream or the water delivery hose and the siphon water absorption side water delivery hose .

  The air pushing member 50 is for pushing out the residual air H remaining in the water supply hose 10 from the discharge port 10a by flowing in the water supply hose 10 as shown in FIG.

  Before the insertion, the air pushing member 50 may be larger than the inner cross section of the water supply hose 10 and may be the same as or slightly smaller than the inner cross section by the insertion. For example, the air pushing member 50 is made of a flexible material such as sponge, and is larger than the inner cross section of the water supply hose 10 before insertion or delivery, and the same as the inner cross section of the water supply hose 10 at insertion or delivery. Or a form in which a flexible material (for example, toilet paper) that can be dissolved in water is coated around the hard core material, and the surroundings are removed while flowing in the water supply hose 10. Be Such an air pushing member 50 pushes forward the downstream air while pushing up the downstream air by the water pressure generated by the water flow in the water supply hose 10, and is finally discharged from the discharge port 10a together with the air. In addition, as long as it is the same as or slightly smaller than the inner cross section of the water supply hose 10 after insertion or delivery, the shape before insertion or delivery is not particularly limited.

  If the form of the air pushing member 50 is a form which can advance the inside of the water supply hose 10 while pushing out the air in the water supply hose 10, the material and the form in particular are not limited.

  The air pushing member delivery unit 60 for delivering the air pushing member 50 into the water supply hose 10 will be described. When the air pushing member delivery portion 60 is roughly divided into the main stream flow of the water supply hose 10 itself (FIG. 15A), it is not in the main stream flow of the water supply hose 10 but separately on the side of the water supply hose 10 There are cases where an air pushing member delivery device 85 capable of delivering the air pushing member 50 is provided in the water supply hose 10 (FIG. 15B). When provided on the water supply hose 10 itself, the air pushing member 50 is installed in the flexible hose 25 and fixed by the holding member 70, and the air pushing member 50 can be discharged by removing the holding member 70 as needed. When it is provided on the side of the water supply hose 10, it is closed by the pinching member 88 except when the air pushing member 50 is thrown in, and the pinching member 88 is removed and used at the time of throwing.

  Further, in the siphon water delivery apparatus 100 according to the first to fifth embodiments described above, as shown in FIG. 16, it is possible to automatically adjust the amount of drainage according to the water level of the spring part 90. A float 110 which can be set to be positioned on the water surface according to an arbitrary water level, a rod-like connecting member 111 connected to the float 110, and a water absorbing member 115 provided on the side opposite to the float 110 of the connecting member 111 And have. The water absorbing member 115 is entirely formed in a container shape, and includes an on-off valve 115 a capable of opening and closing a water absorbing member water inlet 115 d capable of flowing into and out of water inside and outside the container. The on-off valve 115a is connected to the connection member 111, and when the water level rises, the position of the float 110 is raised, and the on-off valve 115a is formed to open inside the water absorption member 115d for water absorption member of the water absorption member 115. ing. As described above, when the water level of the spring portion 90 rises and it is necessary to open the on-off valve 115 a, it is structured to open along the flow of flowing into the water absorption port 115 d of the water absorption member 115. Therefore, the water pressure that the siphon tries to suck in and the water pressure due to the water depth to the water absorbing member 115 provided in the spring portion 90 overlap to act to open the on-off valve 115a. Therefore, the float for opening the on-off valve 115a can be made small. In addition, the position where the float 110 is attached to the rod-like connecting member 111 is changed to set the water depth so that the water level does not fall any further, and the float 110 necessary for closing the on-off valve 115a at the set water level. A float mounting distance adjustment hole 111a is provided which can calculate the weight by a moment and adjust the mounting position. The angle between the on-off valve 115a and the connecting member 111 is adjusted in the connecting portion 115b for fixing the on-off valve 115a and the connecting member 111, and the water level for closing the on-off valve 115a is set and adjusted by the weight of the float 110. A fixed angle adjustment hole 111b is provided. Further, at this time, as shown in FIG. 17A, the water feeding device water suction port 20a of the water feeding device 20 may be provided in the water absorbing member 115 in a container shape, and the entire water feeding device 20 is covered so as to enter into the water absorbing member 115. It may be arranged. Furthermore, as shown in FIG. 17B, the water absorption port 11a of the first water supply hose 11 for siphon may be provided in the water absorption member 115 in the form of a container separately from the water supply device 20. By disposing the water absorption port 11a forming the large opening in the water absorption member 115, the dust or the like flowing from the water absorption port 115d is sucked from the water absorption port 11a of the first water supply hose 11 forming the large opening. Therefore, it is possible to reduce the possibility of clogging the water feeding device water inlet 20a of the water feeding device formed by the small opening. Also in this case, the entire water supply apparatus 20 may be covered and disposed so as to enter the water absorbing member 115. In these cases, in the water injection joining member 30 for joining the second water supply hose 12 on the water supply equipment side and the first water supply hose 11 on the siphon side, the first water supply hose 11 on the siphon side is below the water supply equipment side water supply hose 20b. By arranging so as to be positioned in the above, it is possible to prevent the earth, sand, etc. flowing in the water supply hose 11 on the siphon side from flowing into the water supply apparatus side water supply hose 20c during the siphon water supply operation.

  As shown in FIG. 18, all members including the float 110, the rod-like connecting member 111 connected to the float 110, and the water absorbing member 115 provided on the side opposite to the float 110 of the connecting member 111 are dustproofed. The water absorbing member may be stabilized by being fixedly disposed in the crucible 120 and the shape and weight of the crucible. At this time, the weight 116 may be provided on the connection member 111. When the water level drops, the position of the float 110 also decreases accordingly, so the on-off valve 115a rotates upward inside the water absorbing member 115 around the mounting portion of the on-off valve as a pivot. Water tightness is secured by firmly adhering to the upper opening. Therefore, by the weight 116 being provided, the force with which the on-off valve tries to rotate upwards is increased by the weight of the weight 116 with the fulcrum as an axis, and the degree of adhesion with the outer peripheral frame portion Is effective. Of course, by continuously providing an elastic material such as rubber, silicon or the like in the outer peripheral frame portion inside the water absorption member 115 d for water absorbing members, the effects of water tightness and water repellency can be further enhanced.

  In the siphon water delivery apparatus 100 according to the present embodiment, as shown in FIG. 19, when the water delivery diameter which is the standard of the water delivery equipment 20 is larger than the diameter of the water delivery hose 10, for example The water supply from the water supply apparatus 20 is branched into a plurality of parts, connected to the water injection merging member 30 connected to the plurality of water supply hoses 10 to supply water, and a plurality of siphon water supply apparatuses 100 can be activated or operated simultaneously A branch water supply member 37 may be used. Further, as shown in FIG. 20, water may be supplied to a plurality of water supply hoses 10 respectively.

  Moreover, about the connection method of the water supply apparatus 20 and the water supply hose 10 in the siphon water supply apparatus 100 concerning this embodiment, centerline A or B of the position of the hole for a bolt according to the difference between water supply apparatus manufacturers and the assumed water pressure. When connecting to the water supply hose 10, the number and position of the bolt holes in the flange of the water supply hose do not match, and the water supply equipment and the water supply hose can not be connected. . It is necessary to avoid the situation where it is not possible to select and connect water transmission equipment even in emergency situations such as disaster response. Accordingly, FIG. 21 shows a connecting member 111 having a flange provided with a notched part 118 for a bolt which is not formed in a hole but in a deep groove so as to enable connection even in various manufacturers and models. According to this, it is possible to use the water supply apparatus without considering the difference in the distance between the bolt fixing holes, the distance between the diagonally located holes (center line), and the number of the holes which are different for each water supply apparatus manufacturer. It becomes possible to connect 20 and the water supply hose 10. Since the bolt notches 118 are formed not in the form of holes but in the form of deep grooves, within the range of the bolt notches 118, the positions and the number of holes provided in the opposite flange are Connect using equi-tensioned members. As a result, they are fixed within the range of diagonally formed deep groove-shaped bolt notches 118. Moreover, since the difference between the sizes of the center line A and the center line B on the diagonal of the bolt holes of various manufacturers is smaller than the diameter of the bolt holes, the connecting member can be It is characterized by the fact that there is no escape.

  Furthermore, in the siphon water supply apparatus 100 according to the present embodiment, the water absorption member 130 for sand removal may be provided. The water absorption member 130 for sand discharge is provided at the tip of the first water supply hose 11 as shown in FIG. The water absorption member 130 for sand discharge comprises a main water absorption portion 130 a for absorbing water and soil 130 c together and an auxiliary water absorption portion 130 b for absorbing water only. The water absorbing member 130 for sand removal is formed in a cylindrical shape, and the main water absorbing portion 130 a is provided at the tip thereof, and has a diameter that simultaneously absorbs the soil 130 c of the bottom of the spring portion 90. Since the auxiliary water absorption portion 130b has a smaller diameter than the main water absorption portion 130a and is provided at a fixed distance from the main water absorption portion 130a, the main water absorption portion 130a is close to the bottom surface of the spring portion to Even if a large amount of water is inhaled, the auxiliary water absorption portion 130b is provided at a constant interval from the main water absorption portion 130a, so the water is constantly absorbed and mixed with the earth and sand sucked from the main water absorption portion to mix the fluidity of soil The auxiliary water absorbing portion 130b is formed to be secured so that the auxiliary water absorbing portion 130b is coupled in the vicinity of the main water absorbing portion 130a of the sand absorbing water absorbing member 130 to assist the flow of the main water absorbing portion 130a in the direction of joining the water flow of the main water absorbing portion 130a. It is done. By adopting such a configuration, the effect of the auxiliary water absorption portion 130b is that the sediment with reduced fluidity is clogged in the water supply hose in the situation where the main water absorption portion 130a is buried in sand and absorbs a large amount of soil. Thus, the siphon function can be prevented from being stopped, and the water absorbed from the auxiliary water absorbing portion 130b is added to and mixed with the soil 130c sucked from the main water absorbing portion 130a, and the ratio of the absorbed water and sand 130c is reduced to improve fluidity. Thus, the inside of the water supply hose can be prevented from being clogged with the soil 130c.

  Furthermore, as shown in FIG. 23, the auxiliary water absorption portion extension member 130d may be provided so that the water supply portion of the auxiliary water absorption portion 130b can be disposed near the water surface. When sand is discharged using the water absorption member 130 for sand removal, the crater in the mortar shape becomes wider and deeper in order. At the same time as the crater becomes wider and deeper, the water absorption member 130 for sand removal continues to absorb water at the bottom portion at that time. With the water absorption member 130 for sand removal at the bottom, if sediment that has flowed out from the upstream due to a flood etc. flows into the crater, the water absorption member 130 for sand removal is buried in the sediment 140 a together with the auxiliary water absorption part 130 b and the siphon action stops there's a possibility that. Then, when the siphon is reactivated, it is necessary to dig out the water absorption member 130 for sand removal. As a method of omitting the digging operation, the auxiliary water absorption portion extension member 130d is connected to the auxiliary water absorption portion 130b, and the auxiliary water absorption operation is continued at a position where the extension auxiliary water absorption portion 130e of the tip of the auxiliary water absorption portion extension member 130d is not buried in the soil 140a. Place in a position where you can. As a result, water absorbed from the extended auxiliary water absorption portion 130e at a position not embedded in soil is supplied to the main water absorption portion 130a of the tip of the main sand absorption water absorption member 130 at the bottom of the crater embedded in soil. Even when the water absorbing member 130 for sand is buried in earth and sand, the earth and sand will be discharged by the flow of flowing down the sand removing hose by trapping the earth and sand near the main water absorbing portion 130a absorbed from the extended auxiliary water absorbing portion 130e. Since the soil buried by this action is gradually drained and the original crater state is restored, it is possible to continue the siphon draining action while the crater continues to become wider and deeper.

  The present invention is not limited to the embodiment described above, and may be implemented in various modes within the technical scope of the present invention.

  As described in the above-described embodiment, the apparatus can be used as a device for safely and inexpensively draining water in reservoirs such as rivers, lakes, sediment dams, and glacial lakes.
