Description

Technical Field

[0001] The present invention relates to the technical field of static water transportation, and specifically to a new water transportation method and a hydraulic power generation method. Background Art

[0002] In some scenarios such as small reservoirs, steel siphons are often used for drainage. Building a siphon is much cheaper than building a sluice. And compared with building a sluice, a siphon can avoid excavating the dam and the risks of seepage and piping formation. However, the maximum height that a siphon can span over the high water level surface is theoretically 1 atm corresponding to the vertical water column height of 10.3 m. Affected by the gases and water vapor precipitated in the water, the actual maximum height that can be spanned is about 8 m. When the height of the dam is more than 8 m higher than the reservoir water surface, the siphon device cannot be used for drainage. In practical applications, even when the height of the dam is lower than 8 m higher than the reservoir water surface, when building a siphon across the top of the dam, if the height difference between the siphon and the ground at the top of the dam is small, it will also affect traffic. These two factors greatly limit the application of the siphon.

[0003] How to transport static water at a low place to a high place with zero energy consumption is a very valuable topic. For example, it can achieve zero-energy irrigation of farmland higher than the water source in some mountainous areas.

[0004] In addition, in traditional hydraulic power generation, without considering the head loss and generator efficiency loss, the water turbine efficiency is generally between 80% and 94%. The reason why the water turbine efficiency cannot reach 100% is that there will always be a certain flow velocity when the water impacts the water turbine and flows out after rotation, and this kinetic energy is lost, resulting in a low efficiency of static water power generation.

[0005] Therefore, how to achieve static water transportation across any height with zero energy consumption, how to transport static water at a low place to any high place with zero energy consumption, and how to generate electricity with a high power generation rate using static water are technical problems that people urgently hope to solve. Summary of the Invention

[0006] Aiming at the problems existing in the prior art, the object of the present invention is to provide a new water transportation method and a hydraulic power generation method, which can achieve static water transportation across any height with zero energy consumption, can transport static water at a low place to any high place with zero energy consumption, and can generate electricity with a high power generation rate using static water.

[0007] To achieve the above object, the present invention adopts the following technical solutions: A new water transportation method, characterized in that it includes the following steps, A first fixed pulley is arranged at a high point that needs to be crossed, a second fixed pulley and a fourth fixed pulley are arranged on both sides of the first fixed pulley, the fourth fixed pulley is arranged at the water source, and the second fixed pulley is arranged at a low target water delivery point; several fixed pulleys for supporting the steel cable can also be added along the steel cable as needed.

[0008] A third fixed pulley is arranged between the second fixed pulley and the fourth fixed pulley, and the third fixed pulley is located below the first fixed pulley; a steel cable is sleeved on the first fixed pulley, the second fixed pulley, the third fixed pulley and the fourth fixed pulley to form a closed loop; and a plurality of water buckets are evenly hung on the steel cable; A first blocking device is arranged at the second fixed pulley, and a second blocking device is arranged at the fourth fixed pulley, and both the first blocking device and the second blocking device correspond to the lower part of the water bucket; The steel cable is activated by external force to form a zero-energy self-circulating motion and drive the bucket to move; During the circular motion of the steel cable, the second blocking device blocks the lower part of the water bucket passing the fourth fixed pulley, causing the water bucket to flip over and fill with water from the water source. Then, the water bucket moves upward toward the first fixed pulley along with the steel cable, and continues to move downward toward the second fixed pulley after crossing the high point. The first blocking device blocks the lower part of the bucket moving from the first fixed pulley to the second fixed pulley, so that the bucket turns over and pours water at the target water delivery point, and then the empty bucket moves toward the third fixed pulley along the steel cable; The water bucket moves toward the fourth fixed pulley after passing the third fixed pulley along with the steel cable, thus forming a cycle.

[0009] Furthermore, the steel cable is started manually, including the following steps: filling the top water bucket on the steel cable between the first fixed pulley and the second fixed pulley with water, causing the steel cable to slowly rotate along the first fixed pulley toward the second fixed pulley, repeating the above water injection operation until the steel cable starts to rotate continuously and then stops injecting water.

[0010] Furthermore, the steel cable is started by a starting motor, which includes the following steps: a starting motor is arranged on the first fixed pulley, the second fixed pulley, the third fixed pulley or the fourth fixed pulley, and the steel cable is driven to move by the output shaft of the starting motor; and the starting motor is stopped when the steel cable continues to rotate.

[0011] Furthermore, the method of starting by the starter motor is to arrange the first fixed pulley, the second fixed pulley, the third fixed pulley or the fourth fixed pulley coaxially with the starter motor.

[0012] Furthermore, the first fixed pulley, the second fixed pulley, the third fixed pulley and the fourth fixed pulley are all fixed by a column and a horizontal axis. The fixing method is that the column is fixed to the ground, and a horizontal axis is set at the top of the column. The length of the horizontal axis is greater than half the width of the bucket. The centers of the first fixed pulley, the second fixed pulley, the third fixed pulley and the fourth fixed pulley are all rigidly connected to one end of the horizontal axis.

[0013] Further, the method of hanging the water bucket on the steel cable is to use a fixed cable grip to hang the water bucket. The fixed cable grip includes a horizontal shaft and a suspension arm. The horizontal shaft is fixedly connected to the steel cable, the upper end of the suspension arm is hinged to the horizontal shaft, the water bucket is provided with a rotatable handle, and the lower end of the suspension arm is connected to the handle; the water bucket is provided with an H-shaped suspension head, and the handle is connected to the H-shaped suspension head.

[0014] Further, a braking bucket-blocking rope is arranged between the first fixed pulley and the second fixed pulley. The braking bucket-blocking rope is arranged at a position slightly higher than the water surface of the water source. When it is necessary to stop the steel cable, the braking bucket-blocking rope is used to make the water bucket turn over and pour water. As the steel cable circulates, there are more and more empty buckets between the braking bucket-blocking rope and the second fixed pulley. When the vertical height difference occupied by the water-filled buckets between the first fixed pulley and the second fixed pulley is equal to the vertical height difference occupied by the water-filled buckets between the fourth fixed pulley and the first fixed pulley, the steel cable stops rotating.

[0015] Further, an extended water bucket is hung on the steel cable, and a water conveyance blocking device is arranged between the first fixed pulley and the fourth fixed pulley. The water conveyance blocking device is arranged at the height position where water needs to be conveyed. As the steel cable circulates, the extended water bucket filled with water from the water source is blocked by the water conveyance blocking device and turns over and pours water at the height position where water needs to be conveyed, realizing the conveyance of water from a water source at a lower position to a higher position.

[0016] A power generation method includes the following steps. Using the above water conveyance method to make the steel cable form a zero-energy consumption self-circulating motion and the first fixed pulley, the second fixed pulley, the third fixed pulley, and the fourth fixed pulley rotate; Connect the first fixed pulley, the second fixed pulley, the third fixed pulley, or the fourth fixed pulley to the input shaft of the first generator, and use the rotation of the first fixed pulley, the second fixed pulley, the third fixed pulley, and the fourth fixed pulley to drive the input shaft of the first generator to realize the power generation of the first generator.

[0017] Further, it also includes the following steps. Using the above water conveyance method to make the steel cable form a zero-energy consumption self-circulating motion, and making the water-filled bucket be blocked by the first blocking device and turn over and pour water; Arrange the second generator with a water turbine below the left of the first blocking device, and use the water poured out of the water bucket to impact the water turbine through the water diversion trough to make it rotate, and then drive the rotation of the second generator to generate electricity.

[0018] Generally speaking, the present invention has the following advantages: The present invention converts the potential energy difference between the water source and the target water delivery point into the kinetic energy required for the cyclic rotation of the steel cable, and ingeniously combines two blocking devices so that the water bucket hanging on the steel cable can be flipped when passing through, so that water can be filled at the water source and poured at the target water delivery point respectively. The present invention realizes static water delivery across any height with zero energy consumption, is easy to install and maintain, energy-saving and environment-friendly, and has wide popularization value.

DETAILED DESCRIPTION OF THE INVENTION

[0026] The method of the present invention can deliver water at a high place to a low place across any height with zero energy consumption, or deliver static water at a low place to any high place. At the same time, the potential energy of water can be converted and utilized for power generation, and the efficiency of converting potential energy into electrical energy can be infinitely close to 100%.

[0027] The following is a further detailed description of the present invention.

[0028] As Figure 6 shown in the schematic diagram of the basic principle of the zero - energy - consumption water - conveying device for crossing any high altitude, through this device, water at the high - altitude water source on the left can be conveyed to the low - altitude drainage point on the right, which is lower than the water surface of the left - hand water source, across a dam with a certain height h1, with zero energy consumption. A rope is strung across the outer groove of the fixed pulley. Assume that the weight per unit length of the rope is uniform and is G. Take an infinitesimal length ΔL at any point on the left - hand side of the fixed pulley's rope and perform a force analysis as shown in Figure 6 the following: Let the angle between the left - hand side rope of the fixed pulley and the horizontal line be α, the weight of the infinitesimal length ΔL be ΔG, and the pulling force along the rope direction downward be ΔGsinα. The length of the left - hand side rope of the fixed pulley is h1 / sinα, the weight of the left - hand side rope of the fixed pulley is G1 = Gh1 / sinα, and the pulling force along the rope direction downward of the left - hand side rope of the fixed pulley is: T1=(Gh1 / sinα)·sinα = Gh1; Similarly, the pulling force along the rope direction downward of the right - hand side rope of the fixed pulley is: T2=(Gh2 / sinβ)·sinβ = Gh2; From the expressions of T1 and T2, it can be seen that the values of T1 and T2 are independent of the angle between the rope and the horizontal plane, and are only proportional to the vertical height difference h between the rope end point and the fixed pulley, and proportional to the weight G per unit length of the rope. If the weight per unit length of the rope is uniform, then as long as h2 > h1 is ensured, the rope will rotate clockwise through the fixed pulley.

[0029] Using the above - mentioned basic principle, the inventor has designed a new water - conveying method that can cross any height with zero energy consumption and a hydraulic power - generation method that generates electricity using the static water - height power - generation rate.

[0030] As Figure 1 shown, a new water - conveying method uses a new water - conveying device to convey water at the high - altitude water source 71 on the left across a dam with a certain height to the target water - conveying point 72 on the right, which is lower than the water surface of the left - hand water source 71, with zero energy consumption.

[0031] The water - conveying device includes a first fixed pulley 11, a second fixed pulley 12, a third fixed pulley 13, a fourth fixed pulley 14, and a steel cable 8; The first fixed pulley 11 is arranged at the high point to be crossed, and the third fixed pulley 13 is located below the first fixed pulley 11; The fourth fixed pulley 14 and the second fixed pulley 12 are respectively located on both sides of the first fixed pulley 11. The fourth fixed pulley 14 is used to be arranged at the water source 71, the second fixed pulley 12 is used to be arranged at the target water - conveying point 72, and the position of the fourth fixed pulley 14 is higher than that of the second fixed pulley 12; The steel cable 8 is sleeved on the first fixed pulley 11, the second fixed pulley 12, the third fixed pulley 13 and the fourth fixed pulley 14 to form a closed loop; A plurality of water buckets 6 are evenly hung on the steel cable 8, preferably arranged at equal intervals.

[0032] As Figure 2 As shown, each fixed pulley is fixed on the top of the column 42 through a horizontal axis 41 at the center. The horizontal axis 41 has a certain length so that the water bucket 6 will not touch the column 42 when passing under the fixed pulley. The inside of the fixed pulley has the same internal structure as the flywheel and has the characteristic of one-way rotation, and can only rotate under the drive of the clockwise rotation of the steel cable 8. It has the characteristics of flexible rotation and extremely small friction.

[0033] A first blocking device is provided at the second fixed pulley 12, and a second blocking device is provided at the fourth fixed pulley 14. Both the first blocking device and the second blocking device correspond to the lower part of the water bucket 6; Among them, the steel cable 8 is used to start through an external force to form a zero-energy self-circulating motion and drive the water bucket 6 to move. The second blocking device is used to block the lower part of the water bucket 6 passing through the fourth fixed pulley 14, so that the water bucket 6 turns over and fills with water from the water source 71 and then moves upward along with the steel cable 8 in the direction of the first fixed pulley 11; the first blocking device is used to block the lower part of the water bucket 6 moving downward from the direction of the first fixed pulley 11 to the second fixed pulley 12, so that the water bucket 6 turns over and pours water at the target water delivery point 72 and then moves along with the steel cable 8 in the direction of the third fixed pulley 13 and continues to move to the fourth support point to complete the circular motion.

[0034] Figure 1 In, the empty water bucket 6 is represented by a hollow circle, and the water bucket 6 after being filled with water is represented by a solid circle.

[0035] As Figure 3 As shown, a fixed cable gripper 5 is arranged at a certain distance on the steel cable 8, and the water bucket 6 is hung below the fixed cable gripper 5. The fixed cable gripper 5 includes a horizontal shaft 51 and a suspension arm 52. The horizontal shaft 51 is fixedly connected to the steel cable 8, and the upper end of the suspension arm 52 is hinged to the horizontal shaft 51. The suspension arm 52 can freely rotate around the horizontal shaft 51 perpendicular to the steel cable 8, so that the suspension arm 52 always remains vertically downward. The water bucket 6 is provided with a rotatable handle 53, and the lower end of the suspension arm 52 is connected to the handle 53. The water bucket 6 is provided with an H-shaped suspension head 54, and both ends of the handle 53 are connected to the H-shaped suspension head 54. The water bucket 6 is hung on the H-shaped suspension head 54 of the handle 53 of the water bucket 6 through a round-hole bucket ear 55 to ensure that the water bucket 6 always keeps the bucket mouth facing up and vertically hanging only under the action of gravity.

[0036] An optional braking device is provided between the first fixed pulley 11 and the second fixed pulley 12. The position of the optional braking device is higher than the water surface of the water source 71, and the optional braking device corresponds to the lower part of the water bucket 6 for tipping the water bucket 6 to pour water. When it is necessary to stop the cable 8 that is rotating, the optional braking device can be enabled.

[0037] The blocking device and the optional braking device can adopt various mechanisms that can block the water bucket 6 to make it turn over during the movement. In this embodiment, the first blocking device is the first bucket-blocking rope 21; the second blocking device is the second bucket-blocking rope 22, and the position of the second bucket-blocking rope 22 is slightly higher than the water surface of the water source 71; the optional braking device is the braking bucket-blocking rope 24.

[0038] The cable 8 can be started in two starting modes to form a zero-energy self-circulating movement.

[0039] The first is the manual mode: When starting, just fill the uppermost water bucket 6 among all the water buckets 6 on the cable 8 between the first fixed pulley 11 and the second fixed pulley 12 with water. During the water injection process, the cable 8 will slowly rotate clockwise. Then still repeat the operation to fill the highest water bucket 6 among all the water buckets 6 on the cable 8 between the first fixed pulley 11 and the second fixed pulley 12 with water. Repeat this operation many times until the cable 8 starts to rotate continuously clockwise, and then the zero-energy water transfer from the high place to the low place can be realized. The specific operation is as follows: During the process of filling the bucket 6 at the highest point between the first fixed pulley 11 and the second fixed pulley 12 with water, the steel cable 8 slowly rotates clockwise under the gravity of the water. The bucket 6 filled with water and immersed below the water surface of the water source 71 under the fourth fixed pulley 14 will gradually rise out of the water surface. Then, the bucket 6 at the uppermost left side of the first fixed pulley 11 rotates clockwise to the uppermost right side of the first fixed pulley 11. Then fill this bucket 6 with water. The steel cable 8 slowly rotates clockwise under the gravity of the water. At this time, the bucket 6 filled with water and immersed below the water surface of the water source 71 under the fourth fixed pulley 14 will gradually rise out of the water surface. Then, the bucket 6 at the uppermost left side of the first fixed pulley 11 rotates clockwise to the uppermost right side of the first fixed pulley 11. Then fill this bucket 6 with water. The steel cable 8 slowly rotates clockwise under the gravity of the water... Repeat the above operation, that is, always fill the bucket 6 at the uppermost right side of the first fixed pulley 11 with water. Next, there are two cases: First, if the inclination angle α of the steel cable 8 between the first fixed pulley 11 and the fourth fixed pulley 14 is less than the inclination angle β of the steel cable 8 between the first fixed pulley 11 and the second fixed pulley 12, the bucket 6 on the left side of the first fixed pulley 11 can always rotate to the right side of the first fixed pulley 11. Only need to fill the bucket 6 that continuously appears at the highest point on the right side of the first fixed pulley 11 with water until the steel cable 8 continuously rotates clockwise, then it can achieve zero-energy consumption to transport the water from a high place to a low place. Second, if the inclination angle α of the steel cable 8 between the first fixed pulley 11 and the fourth fixed pulley 14 is greater than the inclination angle β of the steel cable 8 between the first fixed pulley 11 and the second fixed pulley 12, the bucket 6 on the left side of the first fixed pulley 11 cannot rotate to the right side of the first fixed pulley 11. At this time, fill the buckets 6 between the first fixed pulley 11 and the second fixed pulley 12 (that is, the empty buckets 6 adjacent to and below the first bucket 6 filled with water) with water one by one from top to bottom until the empty bucket 6 turns to the uppermost right side of the first fixed pulley 11, then fill this empty bucket 6 with water. Repeat the above water filling process until the steel cable 8 continuously rotates clockwise, then it can achieve zero-energy consumption to transport the water from a high place to a low place across any unlimited height.

[0040] The second startup mode is to start through a motor: A startup motor 31 can be set on any one of the four fixed pulleys. The output shaft of the startup motor 31 drives the steel cable 8 to move. In this embodiment, a startup motor 31 is coaxially arranged on the third fixed pulley 13. The unidirectional rotation characteristic fixed pulley is driven by the startup motor 31 to rotate, and then the steel cable 8 is driven to rotate. After the steel cable 8 continuously rotates clockwise, turn off the startup motor 31. The steel cable 8 and each fixed pulley continue to rotate clockwise, then it can achieve zero-energy consumption to transport the water from a high place to a low place across any unlimited height.

[0041] As Figure 1As shown in the figure, when the steel cable 8 rotates clockwise, when the water bucket 6 rotates to the first bucket-blocking rope 21, the lower part of the water bucket 6 is blocked by the first bucket-blocking rope 21 and cannot move with the steel cable 8. However, since the handle 53 of the water bucket 6 is connected to the lower end of the fixed cable gripper 5 below the steel cable 8, the handle 53 of the water bucket 6 still rotates clockwise with the steel cable 8. In this way, the water bucket 6 will be flipped so that the bottom of the water bucket 6 faces up, and the water inside will pour out, achieving the purpose of transporting water across a height to the target input point at a lower place. After passing through the first bucket-blocking rope 21, the water bucket 6 becomes an empty bucket. When the empty bucket rotates clockwise with the steel cable 8 to the second bucket-blocking rope 22, the lower part of the empty bucket is blocked by the second bucket-blocking rope 22 and cannot move with the steel cable 8. However, since the handle 53 of the water bucket 6 is connected to the lower end of the fixed cable gripper 5 below the steel cable 8, the handle 53 of the water bucket 6 still rotates clockwise with the steel cable 8. In this way, the water bucket 6 will be flipped so that the mouth of the water bucket 6 is inclined downward. As the water bucket 6 continues to rotate with the steel cable 8, the water bucket 6 is filled with water. In this way, after passing through the second bucket-blocking rope 22, the empty water bucket 6 is filled with water. When the clockwise rotation of the steel cable 8 is started, the buckets of the upper-layer steel cable 8 of the fourth fixed pulley 14, the first fixed pulley 11, and the second fixed pulley 12 are all filled with water, and the water buckets 6 on the lower-layer steel cable 8 of the second fixed pulley 12, the third fixed pulley 13, and the fourth fixed pulley 14 are all empty buckets. Since the water buckets 6 are evenly arranged on the steel cable 8, and the vertical height difference between the first fixed pulley 11 and the second fixed pulley 12 is greater than the vertical height difference between the fourth fixed pulley 14 and the first fixed pulley 11, according to the theoretical analysis in the "Basic Principle of the Device" section, the steel cable 8 will maintain a clockwise rotation. In this way, the steel cable 8 will rotate clockwise continuously with zero energy consumption, transporting the water at the high water source 71 across any height to a position lower than the position of the water source 71. By using this method to transport water, it does not involve atmospheric pressure. Therefore, the height that can be crossed breaks through the limitation of the vertical height of 10.3 m of the water column corresponding to 1 atm of the traditional siphon device 1, and can cross any height.

[0042] When it is necessary to stop the steel cable 8 from transporting water, only need to activate Figure 1 the braking bucket-blocking rope 24 in it. The working principle of the braking bucket-blocking rope 24 is the same as that of the first bucket-blocking rope 21. The braking bucket-blocking rope 24 is set at a position slightly higher than the water surface of the water source 71. The water bucket 6 blocked by the braking bucket-blocking rope 24 will become an empty bucket. As the steel cable 8 rotates clockwise, there are more and more empty buckets between the braking bucket-blocking rope 24 and the second fixed pulley 12. When the vertical height difference occupied by the water-filled water buckets 6 between the first fixed pulley 11 and the second fixed pulley 12 is equal to the vertical height difference occupied by the water-filled water buckets 6 between the fourth fixed pulley 14 and the first fixed pulley 11, the steel cable 8 stops rotating.

[0043] How to transport static water at a lower position to a higher position with zero energy consumption is a topic with great application value. For example, it can achieve zero-energy irrigation of farmland higher than the water source 71 in some mountainous areas. To transport water to a higher place, in this embodiment, an extended bucket 61 is hung on the steel cable 8, and a water conveyance blocking device is provided between the first fixed pulley 11 and the fourth fixed pulley 14. The water conveyance blocking device is used to block the lower part of the extended bucket 61 to make it turn over and pour water.

[0044] As Figure 4 、 Figure 5 shown, an extended bucket 61 with a downward-extended side wall is set for every certain number of buckets 6 on the steel cable 8. The capacity of the extended bucket 61 is the same as that of other non-extended ordinary buckets 6. A third bucket-blocking rope 23 (i.e., the water conveyance blocking device) is set at the lower left of the bucket 6 at the uppermost part of the first fixed pulley 11. Since the lower part of the extended bucket 61 is provided with a side wall extension part 611, the height at which the third bucket-blocking rope 23 is set can just block the extended bucket 61 that rotates to the uppermost part of the first fixed pulley 11, but cannot block the ordinary bucket 6 that rotates to the uppermost part of the first fixed pulley 11. Therefore, the continuous movement of the steel cable 8 can be maintained. In this way, the extended bucket 61 will pour out the water at the third bucket-blocking rope 23, and the extended bucket 61 will become an empty bucket and rotate with the steel cable 8 from the first fixed pulley 11 to the second fixed pulley 12. As long as the vertical height difference corresponding to the empty bucket from the first fixed pulley 11 to the second fixed pulley 12 is less than the vertical height difference between the water surface of the water source 71 at the fourth fixed pulley 14 and the second fixed pulley 12, this device can continuously rotate clockwise with zero energy consumption, and the water at the water source 71 at the fourth fixed pulley 14 can be continuously transported to the third bucket-blocking rope 23 at the first fixed pulley 11 with zero energy consumption, thus realizing the transportation of water to the required higher place with zero energy consumption.

[0045] As Figure 1 shown, a hydraulic power generation method uses a new type of hydraulic power generation device for power generation. The hydraulic power generation device includes a first generator 321 and the above-mentioned water conveyance device, and the extended bucket 61 and the third bucket-blocking rope 23 are not installed in the water conveyance device. Among them, the first fixed pulley 11, the second fixed pulley 12, the third fixed pulley 13 or the fourth fixed pulley 14 is connected to the input shaft of the first generator 321. Since after the water conveyance device is started, each fixed pulley can keep rotating with zero energy consumption, therefore, by using any fixed pulley to drive the input shaft of the first generator 321 to rotate, high-efficiency hydrostatic power generation can be achieved.

[0046] In this embodiment, the second fixed pulley 12 is coaxially connected to the first generator 321. When the steel cable 8 rotates clockwise to drive the second fixed pulley 12 to rotate, the first generator 321 can be driven to generate electricity. If the friction during the rotation of the device and the efficiency loss of the first generator 321 are ignored, the gravitational potential energy of the water in this device can theoretically be converted into electrical energy almost 100%. Because when the steel cable 8 rotates, a part of the potential energy difference of the water in the water bucket 6 from the water surface of the water source 71 to the first bucket-blocking rope 21 is converted into electrical energy, and the other part is converted into the kinetic energy of the water rotating with the steel cable 8 in the water bucket 6. The efficiency of potential energy conversion into electrical energy, , where E p is the potential energy of the water at the water source, and E k is the kinetic energy of the water rotating with the steel cable 8 in the water bucket 6. Therefore, the smaller the rotation speed of the steel cable 8, the smaller the kinetic energy E k , and the higher the efficiency of converting the potential energy of the water into electrical energy. When the rotation speed of the steel cable 8 approaches zero, the efficiency of converting potential energy into electrical energy approaches 100%. This method drives the first generator 321 through potential energy to convert it into electrical energy, while traditional hydroelectric power generation first converts potential energy into the kinetic energy of water flow, and then the water flow impacts the water turbine to rotate, and then drives the generator to rotate to convert it into electrical energy. Currently, for conventional hydroelectric power generation without considering the head loss (corresponding to the influence of the friction during the rotation of this device) and the efficiency loss of the first generator 321 (corresponding to the efficiency loss of the first generator 321 of this device), the efficiency of only the water turbine is generally between 80% and 94%. That is to say, this method improves the traditional water turbine efficiency from 80% to 94% to almost 100% that can be achieved by this device. In addition, the water turbine works underwater, and it is inconvenient for installation, connection, maintenance and repair. It has high requirements for the waterproofness of the device and high costs. The fixed pulley of this method is convenient for installation, connection, maintenance and repair, has no requirement for the waterproofness of the device, and has low costs.

[0047] This embodiment also provides another combined hydroelectric power generation method, which uses another new type of hydroelectric power generation device for power generation. This hydroelectric power generation device includes a second generator 322 and the above-mentioned water conveyance device, and the extended water bucket 61 and the third bucket-blocking rope 23 are not installed in this water conveyance device. A water turbine 323 is provided below the second generator 322, and the water turbine 323 is correspondingly arranged at the lower left of the first blocking device. The water in the water bucket 6 is poured into the water diversion trough 324 by flipping the first blocking device, and the water impacts the water turbine 323 to rotate through the water diversion trough 324, and then drives the second generator 322 to rotate for power generation. Since the steel cable 8 can drive the water bucket 6 to fill and pour water with zero energy consumption, the kinetic energy of pouring water from the water bucket 6 can be used to drive the water turbine 323 to rotate, and then drive the second generator 322 to rotate to realize the power generation of the second generator 322. These two power generation methods are implemented simultaneously, so that the kinetic energy E in the efficiency formula of converting the potential energy of water into electrical energy in kIt is also maximally converted into electric energy, making the power generation efficiency η close to 100%.

[0048] The zero-energy consumption method for transporting water across any high elevation for power generation of the present invention transports water at a high place to a low place across any height under zero energy consumption, breaking through the limitation of the vertical height of the water column corresponding to 1 atm of the siphon tube, which is 10.3 m. This feature greatly expands the application range of the device. In addition, compared with transporting water through a steel siphon tube, transporting water by this method has the following 10 advantageous features: 1. The crossing height is not limited. This method is not restricted by air pressure, breaking through the limitation of the water column height corresponding to 1 atm, which is 10.3 m, and can reach any height.

[0049] 2. Low cost. The device adopted by this method has a lower cost than a steel siphon tube.

[0050] 3. Easy to install; the device adopted by this method has a soft structure and is convenient to lay according to the terrain and topography. It avoids the need for a steel siphon tube to change direction when the terrain has high and low undulations, resulting in too many welded joints or direction-changing connectors, which are all prone to air leakage and thus affect the siphon effect.

[0051] 4. Easy to move; the device adopted by this method is easy to move and is convenient to disassemble and install at a new position with different terrain and topography. A steel siphon tube cannot be moved, and when installing at a new position, it is necessary to re-design the length of the steel siphon tube, the turning angle of the joint, etc. according to the terrain, topography, and dimensions of the new position, and the original siphon tube can basically no longer be used.

[0052] 5. Strong versatility. Installing the device adopted by this method does not require customization according to the terrain and topography; 6. No need for maintenance. The device adopted by this method can be used all year round and hardly requires any maintenance. Unlike a siphon tube, when the airtightness is poor, it will affect the siphon effect and even make it unable to be used.

[0053] 7. When using this method for power generation, the gravitational potential energy of water can theoretically be infinitely close to 100% converted into electric energy. In traditional hydroelectric power generation, without considering the head loss and generator efficiency loss, the water turbine efficiency is generally between 80% and 94%.

[0054] 8. The main generator adopted by this power generation method is the first generator 321 coaxially connected to a fixed pulley, which is far from the water surface, and is convenient for installation, connection, maintenance, and repair, with low cost. In traditional hydroelectric power generation, the water turbine works underwater, which is inconvenient for installation, connection, maintenance, and repair, has high requirements for the waterproofness of the device, and has high cost.

[0055] 9. This method can transport water to a high place with an arbitrary high lift. When transporting water to a high place, the lift higher than the water source 71 can be arbitrarily high.

[0056] 10. In addition to transporting liquids such as water with zero energy consumption, the device can also transport solids with zero energy consumption. Simply load the solids to be transported into the water bucket at the fixed pulley. This function can be used to transport the sediment of the riverbed of above-ground rivers such as the Yellow River to the outside of the river embankment with zero energy consumption, or to transport the sediment deposited upstream of the dam to the downstream of the dam with zero energy consumption.

[0057] The above embodiments are the preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention shall be equivalent replacement methods, as well as those for transporting solids, and are all included in the protection scope of the present invention.
