Description

Technical Field

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

[0002] In some scenarios such as small reservoirs, steel siphons are often used for drainage. Building a siphon costs much less than building a sluice. And compared with building a sluice, a siphon can avoid excavating the dam and the risk of seepage and piping. However, the maximum height that a siphon can span above the high water level surface is theoretically 1 atm corresponding to the vertical water column height of 10.3 m. Affected by the gas 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 above 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 convey 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 - consumption 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 efficiency of the water turbine alone is generally between 80% and 94%. The reason why the water turbine efficiency cannot reach 100% is that there is always 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 static water power generation efficiency.

[0005] Therefore, how to achieve static water transportation across any height with zero energy consumption, how to convey 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 purpose of the present invention is to provide a new type of water conveyance device and a hydraulic power generation device, which can achieve static water transportation across any height with zero energy consumption, can convey 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 - mentioned purpose, the present invention adopts the following technical solutions: A new type of water conveyance device includes a first fixed pulley, a second fixed pulley, a third fixed pulley, a fourth fixed pulley and a steel cable; several fixed pulleys for support can also be added along the steel cable according to needs to support the steel cable.

[0008] The first fixed pulley is arranged at a high point, and the third fixed pulley is located below the first fixed pulley; The fourth fixed pulley and the second fixed pulley are respectively located on both sides of the first fixed pulley. The fourth fixed pulley is used to be arranged at the water source, and the second fixed pulley is used to be arranged at the low-lying target water delivery point. The position of the fourth fixed pulley is higher than that of the second fixed pulley. The 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. 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. Both the first blocking device and the second blocking device correspond to the lower part of the water bucket. Among them, the steel cable is used to form a zero-energy self-circulating motion through external force and drive the water bucket to move. The second blocking device is used to block the lower part of the water bucket passing through the fourth fixed pulley, so that the water bucket turns over and fills with water from the water source and then moves upward along the steel cable in the direction of the first fixed pulley. The first blocking device is used to block the lower part of the water bucket moving downward from the direction of the first fixed pulley to the second fixed pulley, so that the water bucket turns over and pours water at the target water delivery point and then moves along the steel cable in the direction of the third fixed pulley.

[0009] Further, a starting motor is arranged on the steel cable, and the first fixed pulley, the second fixed pulley, the third fixed pulley or the fourth fixed pulley is connected to the output shaft of the starting motor.

[0010] Further, the first fixed pulley, the second fixed pulley, the third fixed pulley and the fourth fixed pulley are all provided with a horizontal shaft and a column for fixing to the ground. The centers of the first fixed pulley, the second fixed pulley, the third fixed pulley and the fourth fixed pulley are respectively rigidly connected to one end of the horizontal shaft, and the other end of the horizontal shaft is fixedly connected to the column. The length of the horizontal shaft is greater than half of the width of the water bucket.

[0011] Further, an optional braking device is arranged between the first fixed pulley and the second fixed pulley. The position of the optional braking device is higher than the water surface of the water source. The optional braking device corresponds to the lower part of the water bucket and is used to make the water bucket turn over and pour water.

[0012] Further, the first blocking device is a first bucket-blocking rope; the second blocking device is a second bucket-blocking rope, and the position of the second bucket-blocking rope is higher than the water surface of the water source. The optional braking device is a braking bucket-blocking rope.

[0013] Further, a fixed cable gripper is arranged on each water bucket. The fixed cable gripper 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, and the water bucket is provided with a rotatable handle. The lower end of the suspension arm is connected to the handle.

[0014] Further, the water bucket is provided with an H-shaped suspension head, and the handle is connected to the H-shaped suspension head.

[0015] Furthermore, an extended water bucket is hung on the steel cable, and a water delivery blocking device is provided between the first fixed pulley and the fourth fixed pulley, and the water delivery blocking device is used to block the lower part of the extended water bucket to make it turn over and pour water.

[0016] A hydroelectric power generation device comprises a first generator and a water delivery device, wherein a first fixed pulley, a second fixed pulley, a third fixed pulley or a fourth fixed pulley is connected to an input shaft of the first generator.

[0017] Furthermore, it also includes a second generator, under which a water turbine is arranged. The water turbine is arranged correspondingly at the lower left of the first blocking device. The water bucket is flipped through the first blocking device to pour water into the water diversion trough, and the water diversion trough impacts the water turbine to make it rotate, thereby driving the second generator to generate electricity.

[0018] In general, the present invention has the following advantages: When working, firstly, the first fixed pulley is set at the high point that needs to be crossed, the second fixed pulley is set at the low target water delivery point, and the fourth fixed pulley is set at the water source; the third fixed pulley is set between the second fixed pulley and the fourth fixed pulley, so that the bucket moves upward from the second fixed pulley along with the steel cable and returns to the fourth fixed pulley after crossing the high point to form a cycle. Since the height difference between the first fixed pulley and the second fixed pulley is greater than the height difference between the first fixed pulley and the fourth fixed pulley, the steel cable can form a zero-energy self-circulating motion after being started by an external force by utilizing the conversion principle of potential energy difference. With the continuous movement of the steel cable, when the bucket hung on the steel cable passes through the water source, the second blocking device blocks the lower part of the bucket passing by to make the bucket flip over, and the bucket is filled with water from the water source. After the bucket is filled with water, it moves upward along the steel cable toward the first fixed pulley, and continues to move downward toward the second fixed pulley after passing the high point at the first fixed pulley. When the bucket passes the target water delivery point, the first blocking device blocks the lower part of the bucket to make the bucket flip over, and the bucket pours water at the target water delivery point. After pouring water, the bucket moves along the steel cable toward the third fixed pulley, and continues to move toward the fourth fixed pulley after passing the high point, thereby forming a cycle of automatically taking water from the water source and pouring water at the target water delivery point. 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 cleverly combines the two blocking devices to make the bucket hung on the steel cable automatically flip over when passing by, so as to achieve filling water at the water source and pouring water at the target water delivery point. The present invention can realize static water transportation across any height with zero energy consumption, is easy to install and maintain, is energy-saving and environmentally friendly, and has wide promotion value.

Detailed implementation manners

[0026] The device of the present invention can deliver water from a high place to a low place across any height with zero energy consumption, or deliver static water from 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 is a schematic diagram of the basic principle of the zero-energy-consumption water delivery device across any high place. Through this device, water at the high water source on the left can be delivered to the low drainage place on the right, which is lower than the water surface of the left water source, across a dam with a certain height h1, with zero energy consumption. The rope is slung over 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 side of the fixed pulley of the rope and make as Figure 6Force analysis shown in the figure: Let the angle between the rope on the left side of the pulley and the horizontal line be α, the weight of an infinitesimal length of ΔL be ΔG, and the pulling force downward along the rope direction be ΔGsinα. The length of the rope on the left side of the fixed pulley is h1 / sinα, the weight of the rope on the left side of the fixed pulley is G1 = Gh1 / sinα, and the pulling force downward along the rope direction of the rope on the left side of the fixed pulley is: T1 = (Gh1 / sinα)·sinα = Gh1; Similarly, the pulling force downward along the rope direction of the rope on the right side of the fixed pulley is: T2 = (Gh2 / sinβ)·sinβ = Gh2; It can be seen from the expressions of T1 and T2 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 basic principle, the inventor designed a new water conveyance device that can convey water with zero energy consumption across any height, as well as a hydraulic power generation device that generates electricity using the static water height power generation rate.

[0030] As Figure 1 shown, a new water conveyance device can convey the water from the high-level water source 71 on the left across a dam of a certain height to the target water conveyance point 72 below the water surface of the left water source 71 with zero energy consumption.

[0031] The water conveyance 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; 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 conveyance point 72, and the position of the fourth fixed pulley 14 is higher than that of the second fixed pulley 12; The steel cable 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, preferably arranged at equal intervals.

[0032] As Figure 2As shown, each fixed pulley is fixed to the top of the vertical column 42 through the horizontal shaft 41 at the center. The horizontal shaft 41 has a certain length so that the water bucket 6 will not touch the vertical column 42 when passing under the fixed pulley. The fixed pulley has the same internal structure as the flywheel and has the characteristic of one-way rotation, and can only rotate when driven by 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 is used to form a zero-energy self-circulating motion through external force activation 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 the steel cable towards the first fixed pulley 11; The first blocking device is used to block the lower part of the water bucket 6 that moves downward from 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 the steel cable towards 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 gripper 5 is provided at a certain distance on the steel cable 8, and the water bucket 6 is suspended below the fixed gripper 5. The fixed 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 rotate freely 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 suspended on the H-shaped suspension head 54 of the handle 53 of the water bucket 6 through the round-hole-shaped bucket ear 55 to ensure that the water bucket 6 always remains upright with the bucket mouth facing up 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. The optional braking device corresponds to the lower part of the water bucket 6 and is used to turn over the water bucket 6 to pour water. When it is necessary to stop the rotating steel cable 8, the optional braking device can be activated.

[0037] The blocking device and the optional braking device can adopt various mechanisms capable of blocking the water bucket 6 to cause it to flip during 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 steel cable 8 can be started in two starting modes to form a zero-energy self-circulating motion.

[0039] The first is the manual mode: When starting, just fill the uppermost water bucket 6 among all the water buckets 6 on the steel cable 8 between the first fixed pulley 11 and the second fixed pulley 12 with water. During the water injection process, the steel cable 8 will slowly rotate clockwise. Then still repeat the operation to fill the water bucket 6 at the highest position among all the water buckets 6 on the steel cable 8 between the first fixed pulley 11 and the second fixed pulley 12 with water. Repeat this operation many times until the steel cable 8 starts to rotate continuously clockwise, and then it is possible to achieve zero-energy transfer of water from a high place to a low place. 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 action of 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, and then this bucket 6 is filled with water. The steel cable 8 slowly rotates clockwise under the action of 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, and then this bucket 6 is filled with water. The steel cable 8 slowly rotates clockwise under the action of 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, it is divided into 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 zero-energy consumption can be achieved 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 the bottom of the first filled bucket 6) 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 zero-energy consumption can be achieved to transport the water from a high place to a low place across any height without limit.

[0040] The second starting mode is to start by the motor: A starting motor 31 can be set on any one of the four fixed pulleys. The output shaft of the starting motor 31 drives the steel cable 8 to move. In this embodiment, a starting motor 31 is coaxially arranged on the third fixed pulley 13. The starting motor 31 drives the fixed pulley with unidirectional rotation characteristics to rotate, and then drives the steel cable 8 to rotate. After the steel cable 8 continuously rotates clockwise, turn off the starting motor 31. The steel cable 8 and each fixed pulley continue to rotate clockwise, then zero-energy consumption can be achieved to transport the water from a high place to a low place across any height without limit.

[0041] As Figure 1As shown, when the steel cable 8 rotates clockwise, when the bucket 6 rotates to the first bucket-blocking rope 21, the lower part of the 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 bucket 6 is connected to the lower end of the fixed gripper 5 under the steel cable 8, the handle 53 of the bucket 6 still rotates clockwise with the steel cable 8. In this way, the bucket 6 will be flipped so that the bottom of the bucket 6 faces up, and the water inside will pour out, achieving the goal 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 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 bucket 6 is connected to the lower end of the fixed gripper 5 under the steel cable 8, the handle 53 of the bucket 6 still rotates clockwise with the steel cable 8. In this way, the bucket 6 will be flipped so that the mouth of the bucket 6 is inclined downward. As the bucket 6 continues to rotate with the steel cable 8, the bucket 6 is filled with water. In this way, the empty bucket 6 is filled with water after passing through the second bucket-blocking rope 22. When the clockwise rotation of the steel cable 8 is started, the buckets on the upper layer of the 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 buckets 6 on the lower layer of the 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 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 without energy consumption and never stop, transporting the water at the high water source 71 across any height to a position lower than the position of the water source 71. This device does not involve atmospheric pressure, so the height it can cross 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 and can cross any height.

[0042] When it is necessary to stop the water conveyance of the steel cable 8, only the Figure 1 brake bucket-blocking rope 24 needs to be activated. The working principle of the brake bucket-blocking rope 24 is the same as that of the first bucket-blocking rope 21. The brake bucket-blocking rope 24 is set at a position slightly higher than the water surface of the water source 71. The bucket 6 blocked by the brake 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 brake bucket-blocking rope 24 and the second fixed pulley 12. When the vertical height difference occupied by the water-filled 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 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 from a lower place to a higher place with zero energy consumption is a topic with great application value. For example, it can achieve zero - energy - consumption 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 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 top 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 and topple the extended bucket 61 rotating to the top of the first fixed pulley 11, but cannot block the ordinary bucket 6 rotating to the top 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 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 rotate continuously 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 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 rotate 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 device 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 generator efficiency loss (corresponding to the generator efficiency loss of this device), only the efficiency of the water turbine is generally between 80% and 94%. That is to say, this device improves the traditional water turbine efficiency from 80% to 94% to almost 100% that this device can approach. 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 device is convenient for installation, connection, maintenance and repair, has no requirements for the waterproofness of the device, and has low costs.

[0047] The hydroelectric power generation device also includes another combined power generation structure: the second generator 322. A water turbine 323 is provided below the second generator 322. The water turbine 323 is correspondingly arranged at the lower left of the first blocking device. By flipping the water bucket 6 to pour water through the water diversion trough 324 by the first blocking device, the water turbine 323 is impacted to rotate, thereby driving the second generator 322 to generate electricity. 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 and generate electricity. 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 k is also maximally converted into electrical energy, making the power generation efficiency η approach 100%.

[0048] The zero-energy-consuming device for transporting water and generating electricity across any height of the present invention can transport water at a high place to a low place 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 characteristic greatly expands the application range of the device. In addition, compared with the steel siphon tube, the device has the following 10 advantageous characteristics: 1. The height of crossing is not restricted. This device 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 cost of this device is lower than that of the steel siphon tube.

[0050] 3. Easy to install; this device has a soft structure and is convenient to lay according to the terrain. It avoids the need for the steel siphon tube to change direction when the terrain undulates, which will generate too many welded joints or directional connectors, all of which are prone to air leakage and thus affect the siphon effect.

[0051] 4. Easy to move; this device is easy to move and is convenient to be disassembled and installed at a new position with different terrain. However, the steel siphon tube cannot be moved. When changing the installation position, it is necessary to re-design the length of the steel siphon tube, the turning angle of the connector, etc. according to the terrain, topography and dimensions of the new position, and the original siphon tube can hardly be used anymore.

[0052] 5. Strong versatility. When installing this device in different terrains and topographies, it does not need to be customized according to the terrain and topography; 6. No need for maintenance. This device can be used all year round and hardly needs any maintenance. Different from the siphon tube, when the airtightness is poor, it will affect the siphon effect and even cannot be used.

[0053] 7. The gravitational potential energy of the water in this device can theoretically be infinitely close to 100% converted into electric energy. In hydropower generation, without considering the head loss and the efficiency loss of the generator, generally only the efficiency of the water turbine is between 80% and 94%.

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

[0055] 9. It can transport water to a high place and the lift can be arbitrarily high. 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 by 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 for transporting solids, and are all included in the protection scope of the present invention.
