Abstract

Water vessels, n in number, are stepwise provided in a flowing river, lake or swamp. The water vessel of a subsequent stage is located at a position higher than that of a preceding stage by a predetermined height. Water is introduced into the water vessel of the first stage via a water conduit of which the opening at one end is arranged to oppose to the flow of water utilizing the dynamic pressure produced when the water stream is interrrupted. The level of water introduced into the water vessel rises within a range of dynamic pressure that is produced. The water is pumped from the water vessel of the second stage up to that of the third stage by utilizing external energy obtained by utilizing the flow of water, e.g., energy of dynamic pressure or water hammer pressure wave. The water is thus stepwise pumped up from the water vessels of the preceding stages to that of the succeeding stages. The water is pumped up by a predetermined height each time utilizing the water head produced by the energy of water flow, and cannot be pumped up in a great amount at once. Thus the water is stored in the vessel of the final stage and is allowed to fall to turn the water wheel utilizing the effective head, whereby electricity is generated by a generator. Although dams must be constructed often in locations where the construction conditions are severe, the apparatus of this invention can be easily adapted anywhere where there is a stream of water.

£ If00 / 98dr / l3d ΙΖΠ0 / 88Ο In the case of power generation methods that use power, various secondary pollutions can occur, and in recent years, conventional hydropower generation methods and methods have been proposed. Although the water and equipment have been reviewed, the conventional hydraulic power method and equipment use a well-known communication system to store water. After obtaining the high head required for power generation, the water flowing from the reservoir is guided to the turbine through a large-diameter pipe, and the energy of the water is transferred to the mechanical energy source. The method uses a method of converting the mechanical energy into electrical energy and extracting the mechanical energy to the electrical energy by a generator. Therefore, the following points are pointed out as major ^ 3 issues.

Immediately, (1) there is no suitable geological or geological condition for producing a head difference that is almost vertically, and the standing place is not located anywhere. In addition to unrestricted areas, areas where power demand is high are relatively man-made, where density is high, and in such places, dams should be built. In such a case, the more difficult it is to destroy the living environment of human beings, the more difficult it will be to establish a further floor.

(2) Dam construction requires high construction costs even if it is itself, and indirect costs due to the difference of M in (1) above are considerable. There is a problem.

Therefore, the purpose of the invention is as follows: (1) Compared to the case of dam construction, the energy cost of construction is lower than that of dam construction. In providing the used Kishiden device, Also, it is not limited to the standing place as in the dam method, etc., and if there is a river with flowing water and the space around it, An effective head required for power generation can be obtained, and a device can be provided that can use a water energy source to generate electricity. Disclosure of Kishimei

* The invention has the following technical means to achieve the above objectives.

Immediately, the last discovery is based on two water tanks on a river, lake, or swamp where water flows, so that the water tank in the front stage is higher than the water tank in the front stage. The tank is set up in S, and one end of the first tank is opened facing the flow of ice, such as a river, and at the same time, it is opened downward into the ice. To the top of the water tank, and the other end, which is located above the water surface, can be passed through the opening of the water tank at the first stage. A pipe is arranged, and one end of the tank between the second and subsequent tanks is connected to the bottom of the former tank, which is located on the ice surface. Together with it, it is kneaded by a flowing water pipe that opens downward after the bay turns, then tilts upward, and opens to the next tank. River water The relationship between the height of the surface and the first-stage aquarium is

As shown in the equation, the height of the first-stage water tank is determined by the relationship between the flow velocity of the river and the like, and the height of the first-stage water tank is further determined. The relationship between the heights of the water tanks located in the downstream and the water tanks in the downstream is that the energy of the flow of water, such as rivers, is reduced by the use of water ( The height is set within the range where water can be transferred from the tank to the downstream water tank, and further, necessary gating valves are provided for each of the water supply pipe and the flow water pipe. 'From the tank at the end of the last stage, a water pressure pipe is connected downward and a drop is formed, and the water is positioned at the end of the water pressure pipe. A water turbine that converts energy into mechanical energy and a generator that converts mechanical energy from the ice wheel into electrical energy Water is introduced into the first-stage water tank by the dynamic pressure generated when water from a river or the like is introduced into the water pipe, and after that, the water is discharged. The energy of the flow of water, such as a river, is transferred to the next tank by the lifting head used for moss (|), so that it can be continued. Then, ice is stored in the last tank of the nth stage, water is dropped downward from the last tank, and the power is generated by the effective head. This is a device that generates electricity by pumping water step by step.

In the above, one of the ways to obtain the head for flowing water from the former tank to the latter tank is as follows. In other words, using the symbols used in the attached drawings corresponding to the examples, the first stage tank 1 and the second stage tank 2 described above can be explained.

• A water pipe 12 connecting the n-1st tank and the nth tank is located at the bottom of the previous tank and above the water surface. And one end is kneaded at the end of the part, and it tilts downward, and the other end of the downward tilt faces the ice surface. One end 1S is opened toward the flow of water flowing through the downwardly inclined water pipe 12, and the other end 17 is inclined upward and rises to the next stage Divided into two upwardly inclined tubes 15 through which the openings can pass through the water tank of the first stage and the second stage and the n-th stage Water tank and n stages The height of the giant aquarium, R

• The flow of ice in the downwardly inclined pipe 12 that constitutes the water pipe is controlled by V b

• Open mouth end 18 until the height h ₃ of the liquid level or al on Hohan mixed flow water pipe 15 in the water tank prior stage

• Height from the liquid level in the first tank to the liquid level in the second tank h4

• Change the correction factor to C

• The straight line is r

given that ,

At the point of opening 1 S of the upper oblique tube 15,

Static pressure PS = rh ₃

Total pressure P T-r C li s + ix A)

圧 pressure P m = P T-F S = r h 4

P T P s

Since the relationship of V b = C 2 g is established,

V b = C 2 g h 4

V b ²

h 4

2 g

As shown in the equation, the height of the permanent tank between the front and rear stages is fixed, and the pressure generated at the opening end 18 of the upwardly inclined pipe 15 is reduced in the front tank. This is a lift that uses the energy of the river's water flow to transfer the flies into the water rags at the later stage. The two are as follows. In other words, using the symbols used in the embodiment, the tanks are divided into primary tanks 101A and 102A and secondary tanks 101B and 102B. Separately, a check valve 107 that allows the flow of ice only from the primary water tank to the secondary water tank is arranged between the primary water tank and the secondary water tank, The secondary water tank has a hermetically sealed structure so that an air chamber is formed at the top of the water tank, and is further connected to the bottom of the secondary water tank from the bottom of the next water tank. A flowing water pipe 113 is connected to the next-side water tank, and the water generated by utilizing the flow of ice such as a river in the air chamber of the second-side water tank of each stage water tank. -The pressure wave of the hammer can be introduced, and this pressure wave causes the next wave at a higher position from the water tank in the previous stage. Through the water pipe to the water tank To get the lift to transfer the water.

In the above, the isolation valves of the water intake and the water pipe are in accordance with a program predetermined by the well-known computer control device. Therefore, they can be switched sequentially.

In addition, the amount of ice that can enter the tanks increases as the distance to the later stage increases, but the amount of water decreases gradually. I have to do it. Therefore, the first-stage water tank is composed of a large number of tank groups, and as a whole, forms the first group of the first-stage water tank group. A water pipe is connected to each of the first-stage water tanks in the loop. The tanks after the second stage are also connected to each stage. Similarly, it is composed of a large number of tank groups, and as a whole, forms the 2nd and 3rd groups of the 2nd, 3rd,. In addition, between the tanks of the first group and the respective tanks of the second group, the above-mentioned water pipes are used. The final and final stage of the water tank is composed of a small number of tanks connected to each other, and the ice of each line of the group up to the previous stage. Are being gathered. These can be made possible by selecting the type of inflow pipes and pumping pipes.

In the final stage, the required amount of ice flows down from the tank at the α-th stage through the hydraulic pipe, and the energy of the ice is transferred to the machine energy. Is converted into electrical energy, and mechanical energy is converted into electrical energy, which is supplied to the electric power generator.

According to this method, the water pipe is placed S toward the flow of a river or the like, and water is introduced into the upwardly inclined part of the water pipe by the generated correction. First, the water level was raised above the water level of the river, and the water was flowed into the first stage water tank, which was placed at a height capable of pumping water. At the place where the water has accumulated up to the predetermined level in the first-stage water tank, the water is quickly spilled out through a flowing water pipe, and the water flows down the river. By using the energy to flow water into the second-stage water tank, which is placed at a height that allows pumping, the water is then re-started. Second, raise the water to the point where it is needed, and With regard to the water that decreases as it goes up, the number of water tanks in the preceding stage is made to be much larger than the number of water tanks in the next stage, and the amount of ice is reduced. In this way, the water is discharged downward from the final tank, which is the target, and the power is generated by using the effective head of the water tank. Therefore, it is necessary to use the energy of the river flow at the specified speed and to construct the structural materials such as towers and pipes as a whole. Since it can be built in a building, it has the advantage that it can be built without being restricted by standing conditions compared to dams and the like. Figure 1 Simple explanation attached Figure 1 to 4 show the first embodiment, Fig. 1 is from the 4th tank to the 11th tank Figure 2 is a plan view of Figure 1, Figure 3 is a plan view of Figure 1, and Figure 3 is a view showing the relationship between the water pipe and the first stage tank, Figure 4. Fig. 5 is a diagram showing the relationship between the first-stage water tank and the second-stage water tank. Next, Figs. 5 and 6 show the second embodiment, and Fig. 5 is an elevation view. Figure and Figure 6 are plan views. 0 One practical example Next, a preferred practical example of the invention will be described in detail according to the attached drawing. First, the first embodiment will be described with reference to FIGS. 1 to 4. FIG.

In FIG. 1, 1, 2, 3, ··············· n indicate water tanks each having a predetermined volume. Immediately, the first-stage water tank 1, the second-stage water tank 2, the third-stage water tank 3, ... n-th-stage water tank a are shown. In this case, with respect to the first-stage water tank 1, the second-stage ice tank 2 is located at a certain height, and similarly, with respect to the two-stage huge water tank 2. The third level of water 3 is at the same constant height and height. Immediately, the rear tank is located at a certain height higher than the front tank. These tanks are all mounted on a gantry 6 erected on the bottom 5 of the river 4 in this example. However, without being limited to this example, each tank itself may be erected on land near the river.

Then, a water pipe indicated by reference numeral 7 is kneaded with the first-stage water tank 1. Immediately, the water pipe 7 has an open end 8 facing the flow of the river, and is provided with an S pipe, and in this example, the water pipe 7 is connected to the other end 9.ぃ、いいいいいい傾いいいいいいいいいいいいいいいいい傾傾傾いいい傾い傾傾傾傾傾傾即即即即成成成成即即即構即即構構 It is formed by tilting, and the terminal 9 is opened into the water tank 1. The thickness and length of the water pipe 7 is determined by the

Ogawa no H which requires the used flow speed and the first stage tank 1

The capacity and other curvatures are selected as appropriate, and the upper and lower inclined pipes 10 and the degree of curvature are also set in consideration of the flow path loss.

However, what is important here is that the relationship between the water level L of the river 4 and the height of the first-stage water tank 1 is defined as follows.

• Change the speed of river 6 to V a

• Depth from the ice surface L to the open end 8 of the water pipe 7

1st stage Height of water surface L from water surface L i of water in tank 1 h 2

The correct coefficient is C *

• Specific gravity

given that ,

At a depth ht from the ice surface,

Static pressure P S = r h 1

Total pressure P T = r C i + h 2)

Dynamic pressure P m = P T-P S = rh 2

P T-P s

Since the relationship of V a = C 2 g is established,

V a = C 2 g h 2

V a

h 2

2 g As shown in Equation 2, the height of the first-stage ice tank 1 is determined in relation to the flow velocity of the river 6.

That is, the opening end 8 of the water pipe 7 is opposed to the flow of the river, and when a dynamic pressure Pm is generated there, the dynamic pressure is guided by the dynamic pressure: Ρm; This is based on the natural law that the water level in the upper inclined pipe 11 of the pipe 7 and the water in the water tank 1 rises above the water level L.

Next, reference numeral 12 denotes a downwardly inclined flow tank which is kneaded with the bottom 13 of the first tank 1 and the other end 14 faces the ice surface L of the river. It will be laid over a relatively long distance. The upper obliquely flowing water pipe 15 is passed through the lower obliquely flowing water pipe 12 ¾ through the opening end 18 of the lower obliquely flowing water pipe 12 ¾. The other end 17 of the upwardly inclined water pipe 15 is disposed so as to face the water flow, and the other end 17 of the upwardly inclined water pipe 15 enters the second-stage water tank 2.

The important * here is that the downward flow of water in the inclined water pipe 12 is caused by the water surface L in the first stage tank 1! The difference is due to the head difference h5 between the bottom and the bottom 13, but the greater the pressure generated at the open end 18 of the upwardly inclined water pipe 15, the greater the pressure , the upper side inclined mixed flow water pipe 15及beauty Les bell L ₂ is high rather Do that this whether these input Ru water to the second stage water tank 2, an open σ end of the upper side inclined mixed flow water pipe 15 The position 18 is selected as far as possible from the water surface L of the first stage tank 1 and the water surface of the river: L. 3 The relationship between the height of the first-stage water tank 1 and the position of the second-stage water tank 2 located downstream is

• The flow of ice in the downwardly inclined flow water pipe 12 is

• before the liquid level in the water tank 1 of stage L i or al upper side inclined mixed flow height h ₃ of up to open the mouth end 18 of the water pipe 15

• The height h i from the liquid level L 前 in the first water tank 1 to the liquid level L 2 in the second water tank 2.

• Change the correction factor to C

• Change the specific gravity to r

given that ,

At the point of the open end 16 of the upwardly inclined water pipe 15,

Static pressure P S = r h 3

Total pressure P T = r (h 3 + h 4)

Dynamic pressure P m = FT — PS = rh ₄

P T-P s

Since the relationship of V b = C 2 g is established,

V b ²

h 4 ≠

2 g

The height between the front tank 1 and the rear tank 2 is determined so as to satisfy the equation.

The connection between the downwardly inclined water pipe 12 and the upwardly inclined water pipe 15 between the first stage water tank 1 and the second stage water tank 2 is described in the second stage water tank 2. And third stage aquarium 3, immediately, second stage 4-The following tanks will be used for the entire tank between the first and second tanks. Accordingly, the liquid levels of the water in the third and subsequent water tanks 3 are denoted by L ₃ , L 4,. Other parts are practically the same and have the same reference numerals.

Furthermore, the symbol IL indicates the last-stage aquarium whose purpose is to set the level arrangement of these aquariums as n 俏. The height H of the rag at the end of this stage is set at a place where the water wheel 18 is driven and the mashing machine 13 is driven to generate a head enough to generate power. It is something.

Furthermore, reference numerals 20 and 21 indicate a gate valve, and reference numeral 22 indicates a three-way switching valve. The gate valve 20 is normally ordinarily open, and the three-way switching valve 22 is switched after water is introduced into the other ends 9 and 17 of the respective stages rising into the ice tower. The gate valve 21 is for draining the water into the water tank, and the gate valve 21 is for flowing back after the water is collected in the water tank. Switching of these valves is performed by a known computer device. In order to prevent the water i from decreasing as the height of the tank rises in the aquarium, it will be shown in the second concealment. In addition, the number of water tanks in the first stage is increased by increasing the number of water tanks in the first stage, and the number of water tanks is reduced as the upper stage is reached. Limit to a few numbers. The symbol A indicates the first group of the first-stage tank, B indicates the second group of the second-stage tank, C indicates the third group of the third-stage tank, The ice floe connecting each tank to each stage is connected to the next tank for the corresponding purpose. These modes of connection are selected on the condition of efficient catchment.

Next, the operation of this embodiment will be described. First, the water in the river is supplied first by the water pipe 7 for the first-stage water tank 1 of each of the first-stage group A. It is led to terminal 9 of stage tank 1. It is enabled by the production dynamic pressure described above, and the water level rises within the range of the working pressure. Thereafter, the three-way switching valve 22 is switched to guide the ice in the terminal 9 into the first-stage water tank 1. This behavior is repeated little by little.

Therefore, ice is stored in each of the first tanks 1. Rising above the water level of the water tank 1 of that is shown to office in the sign-1ι ₂ is Ru Oh in limited degree. In this way, when water is stored in each of the water tanks 1 of the first-stage group A, the gate valve 21 is opened. Of water by the will call Tsu by the re-ice head difference h _s in each of the water tank 1 is Ru are flow-directed one in the river 4 through the lower lateral tilt mixed-flow ice tube 1 2. Since the open end 18 of the upwardly inclined water pipe 15 is open on the way, water is generated at the end of the second-stage water tank 2 by the dynamic pressure generated in this part. It goes up to the last 17 places. This is made possible within the range of the dynamic pressure generated at the opening end 18.

And, these operations are performed at the second-stage water tank 2 of each of the second-stage groups JB. in this way Then, if water accumulates at the terminal 17 of each second-stage water tank 2, the three-way cut-off valve 22 is opened by a known computer device. Switch over and introduce water into each of the second-stage water tanks 2. Then, open the sluice valve 21 and send it to the third stage.

In this way, the water is finally collected in the huge water tank H of the second II stage. Since a large amount of water is released to generate a flow of ice in order to generate a dynamic pressure in the middle, the water in the huge tank at the last stage is large. Although the number of tanks is reduced, the number of tanks in the first stage is increased, so that some problems at this point can be prevented.

Then, water is dropped downward from the final tank a through a water pressure pipe, the water wheel 18 is turned, and the water position energy machine is used. It can be converted to mechanical energy, and then the electrical energy can be converted to electrical energy by using electrical power supply 13 to obtain electrical output. That's it.

In addition, since the tanks in the several stages have a predetermined height, the water does not drop from there to the river surface through a thick pipe, so that the water does not drop to the river surface. By dropping water into the lower, lower-sloping downflow pipe, more energy is available for the location of the water. In fact, it is used for cereals in this way.

Next, a second embodiment will be described with reference to the attached drawings, FIG. 5 and FIG. 7 The symbols 101, 102 · · · indicate the first and second tanks, respectively. And they are arranged so that they are in order of height.

In the example of the figure, only the first stage and the second stage are shown, but from the third stage onward, there are n stages to be aimed. The first-stage water tank 1Q1 is divided into a primary ice tank 101A at the same height and a secondary water tank 101B, and the primary tank 1Q1 is divided into a primary water tank 101Q and a primary water tank 101B. A water pipe 103 is connected to the bottom of the water tank 101A. Immediately, the connection is made with the open end 104 facing the flow of the river 105 and the other end 108 standing in the primary water tank 101A.

Next, the secondary water tank 1 Q 1 B is hermetically sealed and connected to the primary water tank 101 A via a pipe 108 having a check valve 107 in the middle. It is tied. The above-mentioned check valve 107 is a valve that allows only the movement of ice from the primary water tank 101A to the secondary water tank 101B.

On the other hand, in response to the first-stage water tank 101, a water hammer—generation means indicated by reference numeral 109 next to the first-stage ice tank 101 is in the middle of the river. Is placed in the S. Immediately, a water tank 110, a water pipe 113 having an open end 111 and a rising terminal 112, and a descending;! K pipe 114, and an upstream stream of the drain pipe 114. Gate valves 115, 118 disposed downstream, a water hammer, a pressure wave generation chamber 117, and a pressure wave transmission tube 118. It is a means of generating hammer. 8 i The above pressure wave transmission tube 1 18 is connected to the upper part of the secondary water line 1Q1Β. And drain valve 1 I 4 gate valve

The position 118 is slightly above the surface of the river. The same applies to the second-stage g tank 102, and the first-stage aquarium arrested above

It has the same structure as 101, except that it is connected to the bottom of the secondary side 1Q1B of the first-stage water tank 101. Flow water pipe 1 1 3 2nd stage Water tank 1 0 2 Primary side water tank

At the point where it is connected to 102A, the code for the secondary tank is 102B. Others have the same symbols as the one-stage giant tank. From then on, the third stage to the 11th stage are the same as the second stage.

And n — From the secondary ice tower in the first tank to the huge tank in the n-th tank, only the ice floe is connected. Ottawahammer pressure wave means are not added. Then, as in the first embodiment, a hydraulic pipe is connected to the third stage water tank, and a turbine generator is arranged below. In this example, the first stage water tank is shown as one, and the second-stage huge water tank is shown as one. However, as in the first embodiment, each stage has many tanks. Numbers are arranged. A pipe in the primary water tank of each water tank is provided with a three-way switching valve indicated by I13.

According to the above method, the first stage water tank 1 (the primary side water tank 101A of U) is supplied with water from the river by the same operation as in the first embodiment. In this case, multiple water pipes 103 are installed. They can be stored in a short time. For storing in the water tank 101A, after storing it in the terminal tube 108, switch the three-way switching valve 113 to introduce it into the water tank 101A. An example is shown. Then, the water stored secondarily enters the secondary-side water tank 101B via the check valve 107. When the amount of water to be stored in the water tank 101B reaches a predetermined, predetermined place, the ice guide tube 1 is placed in the tank 103 on the other side. Ice is also stored via 13. Here, when the sluice valve 1 15 on the upstream side of the drain pipe 114 is suddenly opened, the water in the tank 109 is rushed due to the head of the tank 103 with respect to the river surface. It flows down well, hits the downstream shutoff valve 118, and falls on the river after hitting this shutoff valve 11S. At this point, water collides with the sluice valve 118, causing a water hammer phenomenon to occur in the 18 s of the sluice valve 118, which is a water hammer. The tank chamber which is transmitted to the air in the upper part of the pressure wave generation chamber 118 through the transmission pipe 118, and which is located on the secondary side of the first-stage water tank. It is transmitted to the upper city air of 10 1B and applies pressure to the ice that has been stored below it.

It should be noted that the pressure generated by the water hammer phenomenon is the propagation speed of the pressure wave when the gate valve is suddenly closed. (m / s)

The speed of ice flowing in an ice tube is represented by v (m / s).

G / g If the maximum value of the pressure rise is represented by the head, and h (m),

S

It can be shown by the following equation.

Then, a water hammer pressure wave is generated in the air chamber of the secondary side water tank 101B, and when pressure is applied to the water below the water wave, the water becomes a lift. Thus, the water in the secondary water tank 101B is introduced into the primary tank 1Q2A of the two-stage g water tank 1Q2 via the flowing water pipe 113. For this reason, water is guided from the former aquarium to the next higher aquarium by a head that uses the flow of the river water for vegetation.

In addition, the gate valve 115 on the upstream side of the water drain pipe 114 in the water hammer hammering means 103 is alternately opened and closed at a fixed period.

In this way, water is guided to the final-stage water tank 11 having the predetermined height, and power generation is performed using the effective head as in the first embodiment.

Thus, in the first and second embodiments described above, the water is moved from the preceding water tank to the latter water tank at a certain height. In this case, the dynamic pressure that occurs when water is stopped to obtain the lift and the flow that is generated when the flow of water is suddenly closed are obtained. An example of using a pressure wave by water hammer is shown, but other rivers to be used for water intake,
