Description

Technical Field

[0001] The present invention belongs to the field of handling engineering, and particularly relates to a liquid driving mechanism, a circulating liquid power generation device and a method. Background Art

[0002] In actual production, with the continuous growth of global energy demand and the increasingly prominent environmental problems, the development and utilization of clean energy have become an important topic in today's society. As a renewable and clean energy form, water energy has rich resources and broad application prospects. Traditional hydropower generation is a common renewable clean power generation, but traditional hydropower generation has some defects and deficiencies. It is affected by the dry season for a long time. When the water volume decreases, the power generation decreases sharply, and it cannot well meet the demand for large power generation. It is greatly affected by the natural environment. At the same time, some devices fail to fully optimize the flow path of water flow and the energy utilization efficiency during the water flow driving process, resulting in large energy losses. Summary of the Invention

[0003] (1) Technical Problems to be Solved

[0004] The present invention discloses a liquid driving mechanism and a circulating liquid power generation device, aiming to solve the problem of low power generation when the water volume is small.

[0005] (2) Technical Solutions

[0006] The present invention discloses a liquid driving mechanism, including a box body, a lifting mechanism located at the bottom of the box body, and a lifting mechanism slidably connected in the box body. The lifting mechanism includes a lower piston plate and a lifting member for driving the lower piston plate to lift. The lifting mechanism is located above the lower piston plate, and a chamber one is formed therebetween.

[0007] The lifting mechanism includes a heavy object, an upper piston plate, and a support column connected between the two, so that a chamber two is formed between the heavy object 1 and the upper piston plate. A drain port communicating with the chamber one is provided at the bottom of the upper piston plate, and a connection hole for unidirectionally communicating the chamber one and the chamber two is provided.

[0008] The lifting mechanism further includes a telescopic pipe, which sequentially penetrates through the heavy object and the upper piston plate from top to bottom and communicates with the drain port. A water inlet pipe communicating with the chamber two is provided on the peripheral wall of the box body.

[0009] Furthermore, a stratification mechanism is further provided in the chamber one. The stratification mechanism includes a stratification component and a driving member for driving the stratification component to lift, and the stratification component descends in a staged manner.

[0010] Further, the layered component includes a first layered plate and a second layered plate that can approach or separate from each other. A first through hole is provided in the first layered plate, and a second through hole is provided in the second layered plate. The first through hole and the second through hole are arranged vertically and staggeredly.

[0011] Further, the driving member is a mother-and-son oil cylinder, including a main shaft and a sub-shaft connected to the end of the main shaft. The end of the main shaft is connected to the first layered plate, and the sub-shaft passes through the first layered plate and is connected to the second layered plate.

[0012] Further, at least one layered mechanism is provided in the same first chamber;

[0013] Wherein, when the lifting mechanism descends, the two layered components descend sequentially or alternately.

[0014] The present invention also discloses a circulating liquid power generation device, including two of the liquid driving mechanisms and a water delivery pipeline respectively communicated with the two liquid driving mechanisms; a power generation mechanism is provided in the water delivery pipeline; the telescopic pipe in the liquid driving mechanism is communicated with the water inlet pipe in the other liquid driving mechanism through the water delivery pipeline to realize the circulating flow of the liquid in the two liquid driving mechanisms; a connecting pipe is communicated between the two lifting mechanisms for the lifting fluid in the two lifting mechanisms to flow through.

[0015] Further, the water delivery pipeline includes a pressure pipe and a drain pipe, and the power generation mechanism is arranged between the pressure pipe and the drain pipe.

[0016] Further, the pressure pipe includes a main pipe one, a sub-pipe one and a sub-pipe two. One end of the main pipe one is respectively communicated with the sub-pipe one and the sub-pipe two. The other end of the sub-pipe one is communicated with the telescopic pipe of one liquid driving mechanism, and the other end of the sub-pipe two is communicated with the telescopic pipe of the other liquid driving mechanism; wherein, a control valve one is provided at the connection of the main pipe one, the sub-pipe one and the sub-pipe two.

[0017] Further, the drain pipe includes a main pipe two, a sub-pipe three and a sub-pipe four. One end of the main pipe two is respectively communicated with the sub-pipe three and the sub-pipe four. The other end of the sub-pipe three is communicated with the water inlet pipe of one liquid driving mechanism, and the other end of the sub-pipe four is communicated with the water inlet pipe of the other liquid driving mechanism; wherein, a control valve two is provided at the connection of the main pipe two, the sub-pipe three and the sub-pipe four.

[0018] The present invention also discloses a circulating liquid power generation method, including two sets of the circulating liquid power generation devices, namely group A and group B. The specific steps are as follows:

[0019] Step 1: The lifting mechanism of the liquid driving mechanism in Group A is in the lifting state and the position of the lifting and lowering mechanism is fixed. The jacking mechanism of the liquid driving mechanism in Group B is in the compressed state. At this time, the liquid flows unidirectionally from Chamber II of the liquid driving mechanism in Group A into Chamber I. The weight of the liquid driving mechanism in Group A is greater than that of the liquid driving mechanism in Group B. The liquid pushes the lower piston plate to descend under its own gravity, causing the lifting mechanism in Group A to gradually convert into the compressed state;

[0020] Step 2: During the conversion process, the fluid in the lifting mechanism in Group A gradually flows to the jacking mechanism in Group B and causes the lifting mechanism in Group B to gradually convert into the lifting state, so as to realize the state conversion of the two lifting mechanisms;

[0021] Step 3: After the lifting mechanism in Group A is switched to the compressed state, fix the lifted lifting and lowering mechanism in Group B. The lifting and lowering mechanism in Group A descends under the action of gravity and squeezes the liquid so that the liquid flows into the water supply pipeline and flows through the power generation mechanism and then flows into Chamber II of the lifting and lowering mechanism in Group B to drive the power generation mechanism to work;

[0022] Step 4: The lifting and lowering mechanism in Group B receives the liquid transferred from Chamber I in Group A. At this time, the weight of the liquid driving mechanism in Group B is greater than that of the liquid driving mechanism in Group A, thereby realizing the re-state conversion of the two lifting mechanisms and the cyclic flow of the liquid.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] The two liquid driving mechanisms are linked through a connecting pipe to realize the cyclic flow of the liquid in the system, form a water circulation system, realize the automatic operation of the system and the cyclic utilization of energy, and maximize the utilization of the energy of the liquid; at the same time, a power generation mechanism is arranged in the water supply pipeline to convert the kinetic energy and gravitational potential energy of the liquid into electrical energy, improving the energy utilization efficiency.

Detailed implementation manners

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] As Figures 1-11 shown.

[0039] As Figures 1-4As shown in the figure, the present invention discloses a liquid driving mechanism, which includes a box body 6, a lifting mechanism 14 located at the bottom of the box body 6, and a lifting mechanism 3 slidably connected within the box body 6. The lifting mechanism 14 includes a lower piston plate 143 and a lifting member 144 for driving the lifting of the lower piston plate 143. The lifting mechanism 3 is located above the lower piston plate 143, and a first chamber 11 is formed therebetween;

[0040] The lifting mechanism 3 includes a heavy object 31, an upper piston plate 32, and a support column 34 connected between the two, so that a second chamber 12 is formed between the heavy object 31 and the upper piston plate 32; a drain port 321 communicating with the first chamber 11 is provided in the upper piston plate 32, and a connection hole 322 for allowing the first chamber 11 to communicate with the second chamber unidirectionally is provided. The lifting mechanism 3 further includes a telescopic tube 33. The telescopic tube 33 sequentially passes through the heavy object 31 and the upper piston plate 32 from top to bottom and communicates with the drain port 321. A water inlet pipe 13 communicating with the second chamber 12 is provided on the peripheral wall of the box body 6. A pin 61 for supporting and fixing the lifting mechanism 3 is provided on the box body 6. During operation, first, liquid 4 is injected into the second chamber 12 through the water inlet pipe 13 or by lifting the heavy object 31. The liquid 4 naturally flows into the first chamber 11 through the connection hole 322. At this time, the heavy object 31 is fixed on the box body 6 by the pin 61. A valve body 323 is provided in the connection hole 322 to allow the liquid 4 to flow unidirectionally from the second chamber 12 to the first chamber 11. The heavy object 31 is released, and the heavy object 31 descends under the action of gravity, driving the second chamber 12 to descend. The telescopic tube 33 communicates with the drain port 321 to squeeze and discharge the liquid 4 in the first chamber 11 through the telescopic tube 33, realizing the driving of the liquid 4. The lifting member 144 works to drive the movement of the lower piston plate 143, and then drives the movement of the lifting mechanism 3 to return the heavy object 31 to its original position, realizing the discharge of the liquid 4.

[0041] Further, the pin 61 can be provided on the box body 6 or on the heavy object 31. The pin 61 realizes the fixing or release of the heavy object 31 by means of hydraulic drive or motor drive.

[0042] Further, the telescopic tube 33 is a telescopic pipeline that can be telescoped to adapt to the movement of the second chamber 12.

[0043] Preferably, multiple layers of flexible gill-shaped thin sheets can be arranged in a staggered manner in the connection hole 322, allowing only the liquid 4 to flow from the second chamber 12 into the first chamber 11 through the connection hole 322, and the water in the first chamber 11 cannot flow from the first chamber 11 into the second chamber 12 through the connection hole 322, thereby realizing unidirectional conduction.

[0044] Preferably, a permanent magnet or an electromagnet may also be disposed in the connection hole 322 to form a gradient magnetic field. When the liquid 4 flows from the second chamber 12 to the first chamber 11, the magnetic field does not significantly impede the liquid 4. When flowing in the reverse direction, the magnetic force increases the flow resistance so that the liquid 4 cannot flow from the second chamber 12 to the first chamber 11.

[0045] Preferably, the position of the water inlet pipe 13 may be disposed on the outer wall of the second chamber 12 or penetrate through the heavy object 31 to communicate with the second chamber 12.

[0046] Furthermore, a layering mechanism 5 is further provided in the first chamber 11. The layering mechanism 5 includes a layering component 51 and a driving member 52 for driving the layering component 51 to lift and lower. By providing the layering mechanism 5, the liquid 4 in the first chamber 11 is layered. The layering mechanism 5 separates the liquid 4 into multiple layers, changing the distribution and flow state of the liquid 4 in the first chamber 11. At the same time, under a certain pressure, the total applied energy is fixed. When the amount of the liquid 4 being worked on decreases, it means that these fixed energies can be more concentratedly distributed to fewer liquid 4 molecules. According to the kinetic energy formula Ek = 1 / 2mv 2 , the concentrated energy enables the liquid 4 to obtain a greater velocity v. Even if the mass m is small, the overall kinetic energy can still be increased; the smaller amount of the liquid 4 makes the action of the pressure on the liquid 4 more direct and significant; the liquid 4 is subjected to a greater unit pressure. According to Newton's second law F = ma, under the same pressure F, the smaller the mass m, the greater the acceleration a, so that the velocity can be increased in a shorter time, thereby increasing the kinetic energy. When the amount of the liquid 4 is small, the internal friction and resistance of the liquid 4 are also relatively small. In this way, during the pressure work process, less energy is consumed to overcome the internal resistance, and more energy can be converted into the kinetic energy of the liquid 4, making the increase in the kinetic energy of the liquid 4 more obvious. During operation, when the heavy object 31 descends under the action of gravity, it squeezes the layered liquid 4, and the liquid 4 is discharged through the telescopic pipe 33. Due to the layering effect, the heavy object 31 descends faster, improving the efficiency of discharging the liquid 4.

[0047] Furthermore, as Figures 4-8As shown, in order to achieve the layering of the liquid 4 in the chamber 11, the layering assembly 51 includes a first layering plate 511 and a second layering plate 512 that can approach or separate from each other. A first through hole 5111 is provided in the first layering plate 511, and a second through hole 5121 is provided in the second layering plate 512. The first through hole 5111 and the second through hole 5121 are arranged vertically and staggeredly. During operation, the lifting mechanism 3 is fixed to the side wall of the box body 6, and the liquid 4 is injected into the chamber 12. The liquid 4 first flows from the chamber 12 to the chamber 11. The driving member 52 drives the mutually separated first layering plate 511 and second layering plate 512 to rise. Since the first through hole 5111 and the second through hole 5121 are arranged staggeredly, when the first layering plate 511 contacts the second layering plate 512, an isolation layer is formed between the two. Under the action of the driving member 52, the first layering plate 511 and the second layering plate 512 approach and fit each other to layer the liquid 4 in the chamber 11, so that the liquid 4 cannot flow up and down through the first through hole 5111 or the second through hole 5121. Subsequently, the heavy object 31 is released, and the heavy object 31 descends under the action of gravity, squeezing the liquid 4 in the layered chamber 11 so that the liquid 4 can be discharged more quickly through the telescopic tube 33. This design improves the acceleration of the discharge of the liquid 4.

[0048] Preferably, the layering assembly 51 descends in a stepped manner, and the heavy object 31 can be fixed when the heavy object 31 descends to be close to the second layering plate 512. The driving member 52 drives the layering assembly 51 to move away from each other and then descend a certain height. The driving member 52 drives the first layering plate 511 and the second layering plate 512 to approach and fit each other, thereby re-layering the liquid 4 that has not been discharged in the chamber 11. By providing one layering assembly 51, the effect of multiple layering can be achieved, thereby improving the discharge speed of the liquid 4.

[0049] Preferably, the first layering plate 511 and the second layering plate 512 can also be designed to be rotatable. Multiple radial partitions or protrusions can be provided on each disc, and the position of the partitions or protrusions can be changed by rotation to achieve the layering of the liquid 4. At the same time, the first layering plate 511 and the second layering plate 512 can be designed to be foldable structures. Multiple folding lines or hinges can be provided on each layering plate, and the shape of the layering plate can be changed by folding the layering plate to achieve the layering of the liquid 4. The first layering plate 511 and the second layering plate 512 can also be designed to be plate-like structures with magnetic materials. Under the action of magnetic attraction, the first layering plate 511 and the second layering plate 512 attract or repel each other when needed, so that the lower-layer liquid 4 flows to the upper layer.

[0050] Furthermore, a plurality of layering mechanisms 5 are provided in the same chamber 11 to improve the acceleration of the liquid 4 discharge.

[0051] Preferably, two of the stratifying mechanisms 5 are provided in the same chamber 11, and the two stratifying components 51 are arranged corresponding to each other up and down, so that the chamber 11 is sequentially divided into an upper chamber 111, a middle chamber 112, and a lower chamber 113 from top to bottom; the stratifying plates in each stratifying mechanism 5 can control the flow of the liquid 4 between different layers by approaching or separating from each other, realizing fine adjustment of the liquid 4. During the descent of the heavy object 31, the two stratifying mechanisms 5 work together. First, the upper stratifying mechanism 5 separates and squeezes out the liquid 4 in the upper chamber 111 and the middle chamber 112; subsequently, the lower stratifying mechanism 5 separates and discharges the liquid 4 in the middle chamber 112 and the lower chamber 113;

[0052] Furthermore, the driving member 52 is a mother-and-son oil cylinder, including a main shaft 521 and a sub-shaft 522 connected to the end of the main shaft 521. The end of the main shaft 521 is connected to the first stratifying plate 511, and the sub-shaft 522 passes through the first stratifying plate 511 and is connected to the second stratifying plate 512. When in use, the heavy object 31 is fixed. Since a large water pressure will be generated when the first stratifying plate 511 and the second stratifying plate 512 are connected together and rise synchronously, in order to reduce the influence of the water pressure during rising on the first stratifying plate 511 and the second stratifying plate 512, which causes a large resistance to the flow, the sub-shaft 522 of the driving member 52 drives the second stratifying plate 512 away from the first stratifying plate 511. The driving member 52 drives the two stratifying components 51 to be at different heights in the chamber 11. After the main shaft 521 drives the separated first stratifying plate 511 and the second stratifying plate 512 to rise to a certain height in the chamber 11, the sub-shaft 522 retracts to bring the separated second stratifying plate 512 close to the first stratifying plate 511 to divide the liquid 4 in the chamber 11 into three layers, and the two stratifying components 51 in the same chamber 11 descend in sequence; at this time, the heavy object 31 is released, and the heavy object 31 descends under the action of gravity, first squeezing out the liquid 4 located in the upper chamber 111 separated by the first stratifying plate 511 and the second stratifying plate 512. The upper piston plate 32 descends with the heavy object 31 and abuts against the second stratifying plate 512. Subsequently, the second stratifying plate 512 is driven by the sub-shaft 522 to move away from the first stratifying plate 511. The heavy object 31 descends together with the upper second stratifying plate 512 and abuts against the second stratifying plate 5112 of the lower stratifying mechanism 5 to discharge the liquid 4 in the middle chamber 112. Subsequently, the second stratifying plate 512 of the lower stratifying mechanism 5 separates from the first stratifying plate 511, and the heavy object 31 descends together with the two stratifying components 51 in the chamber 11 to discharge the liquid 4 in the lower chamber 113, and then all the water in the chamber 11 is discharged through the telescopic tube 33;

[0053] Preferably, the two said layered components 51 within the same chamber one 11 descend alternately; during use, the two said layered components 51 are at different heights within the chamber one 11. The pin 61 fixing the heavy object 31 retracts, and the heavy object 31 descends under the action of gravity. The heavy object 31 reaches the second layered plate 512 of the upper layered component 51, and the heavy object 31 and the upper layered component 51 descend together and abut against the second layered plate 512 of the lower layered component 51. The two said layered components 51 abut, and the driving member 52 descends the two abutting layered components 51. The two said layered components 51 separate from each other and do not abut against the heavy object 31, further stratifying the chamber one 11 where the liquid 4 has not been discharged yet. Repeating the above process, multiple stratifications are achieved to discharge the liquid 4 in the chamber one 11. This design effectively improves the acceleration of the discharged liquid 4.

[0054] By means of the layered components 51 located in the same chamber one 11 descending in sequence or alternately, multi-stage stratification of the liquid 4 in the chamber one 11 is achieved. These two methods make the discharge of the liquid 4 more orderly, reduce the mutual interference between the liquids 4, and improve the efficiency of liquid 4 driving. During the ascending or descending process of the layered plates, by reasonably controlling the movement speed and position of the layered plates, and using the mutual cooperation between the layered plates, the flow resistance effect of the water pressure on the layered plates can be effectively reduced, ensuring the smooth movement of the layered plates and the realization of the stratification effect. This multi-stratification design can better adapt to complex liquid 4 conditions and different working requirements, making the entire liquid driving mechanism 1 have stronger versatility and adaptability. By reasonably arranging one or more stratification mechanisms 5 within the limited chamber one 11, making full use of the space, the equipment structure is made more compact, reducing the floor area and volume.

[0055] By designing the driving member 52 as a master-slave oil cylinder, stable thrust and precise displacement control are provided, ensuring that the movement of the first layered plate 511 and the second layered plate 512 is accurate when approaching or separating from each other, achieving precise adjustment of the liquid 4 stratification. At the same time, the design of the master-slave oil cylinder is compact. The combination of the main shaft 521 and the sub-shaft 522 can achieve a large stroke and thrust within a limited space, occupying less space, and having high reliability and load capacity. It can maintain stable working performance during frequent reciprocating movements. At the same time, hydraulic drive has the characteristics of fast response and flexible control, and can adapt to the rapid adjustment requirements of the liquid driving mechanism 1 under different working conditions, improving the working efficiency and performance of the liquid driving mechanism 1.

[0056] Preferably, the shape of the box body 6 can be cylindrical, square, triangular prism-shaped, or polyhedron-shaped, and the shape of the layered component 51 is adapted to the shape of the box body 6.

[0057] Furthermore, in order to keep the two layered components 51 balanced when descending, each layered component 51 is provided with at least two driving members 52, so that the layered components 51 can distribute the driving force more evenly during the lifting process, ensuring that the layered components 51 remain horizontal during the descent, thereby achieving more precise stratification of the liquid 4.

[0058] Another embodiment: A plurality of guide pillars may be further provided between the layer plate 1 511 and the layer plate 2 512 and between the layer plate 1 511 and the lower piston plate 143, so that the layer plate 1 511 and the layer plate 2 512 can move smoothly when approaching or moving away from each other under the action of the driving member 52, thereby avoiding the cutting, shaking or jamming that may occur during the movement, and making the movement of the layer plates more stable and reliable.

[0059] Furthermore, the liquid 4 may be water, salt water or an oily liquid.

[0060] It should be noted that the lifting member 144 and the driving member 52 are preferably oil cylinders in this embodiment; they can also be driven by gear transmission, screw rod structure, etc.

[0061] At the same time, the lifting member 144 can be arranged at the bottom of the box body 6, and can also be arranged on the outer periphery or peripheral wall of the box body 6. In the present embodiment, the lifting member 144 is arranged at the bottom of the box body 6.

[0062] like Figure 9 As shown, the present invention also discloses a circulating liquid power generation device, comprising two liquid driving mechanisms 1 and water supply pipes 2 respectively connected to the two liquid driving mechanisms 1; a power generation mechanism 7 is arranged in the water supply pipe 2; the telescopic pipe 33 in one of the liquid driving mechanisms 1 is connected to the water inlet pipe 13 in the other liquid driving mechanism 1 through the water supply pipe 2, so as to realize the circulation of liquid 4 in the two liquid driving mechanisms 1 to form a water circulation system; a connecting pipe 141 is connected between the two lifting mechanisms 14, and a hydraulic oil circuit reversing valve 142 is arranged on the connecting pipe 141; a lifting fluid is arranged in the lifting mechanism 14;

[0063] The present invention also discloses a circulating liquid power generation method, comprising two groups of the circulating liquid power generation devices, assuming that one of the liquid driving mechanisms 1 is in group A and the other liquid driving mechanism 1 is in group B, at this time, the lifting mechanism 14 of the liquid driving mechanism 1 in group A is in a lifting state, and the lifting mechanism 14 of the liquid driving mechanism 1 in group B is in a compressed state. During operation, the circulating flow of the liquid 4 in the two driving mechanisms 1 and the lifting of the lifting mechanism 14 are realized according to the following steps:

[0064] Step 1: Fix the weight 31 of Group A to the box body 6, inject the liquid 4 into the second chamber 12 of Group A. The liquid 4 in the second chamber 12 of Group A naturally flows through the connection hole 322 to the first chamber 11 of Group A. At this time, the weight of Group A is greater than that of Group B. When the lifting mechanism 14 of Group A changes from the lifting state to the compressed state under the self - gravity of the liquid 4 and the hydraulic oil circuit reversing valve 142 is in the closed state, the lifting fluid in the lifting mechanism 14 of Group A gradually flows through the connecting pipe 141 to the lifting mechanism 14 of Group B.

[0065] Step 2: The lifting mechanism 14 of Group B gradually obtains the lifting fluid from the lifting mechanism 14 of Group A, so that the lifting mechanism 14 of Group B gradually changes from the compressed state to the lifting state. The lifting mechanism 14 of Group B rises and then lifts the lifting mechanism 3 in contact with it.

[0066] Step 3: Fix the lifted weight 31 of Group B on the box body 6, close the hydraulic oil circuit reversing valve 142. At this time, release the weight 31 of Group A. The weight 31 of Group A descends under its own gravity and squeezes the liquid 4 in the first chamber 11 of Group A, so that the liquid 4 flows through the telescopic pipe 33 into the water supply pipe 2 and then flows to the water inlet pipe 13 of the liquid driving mechanism 1 of Group B. The liquid 4 enters the second chamber 12 of Group B through the water inlet pipe 13 to drive the power generation mechanism 7 to work.

[0067] Step 4: The liquid 4 in the second chamber 12 of Group B naturally flows to the first chamber 11 of Group B. At this moment, the weight of the liquid driving mechanism 1 of Group B is greater than that of the liquid driving mechanism 1 of Group A. Open the hydraulic oil circuit reversing valve 142. The liquid 4 in the first chamber 11 of Group B changes the lifting mechanism 14 of Group B in the lifting state to the compressed state under its own gravity. The lifting fluid in the lifting mechanism 14 of Group B gradually flows through the connecting pipe 141 to the lifting mechanism 14 of Group A.

[0068] Step 5: The lifting mechanism 14 of Group A gradually obtains the lifting fluid from the lifting mechanism 14 of Group B, so that the lifting mechanism 14 of Group A gradually changes from the compressed state to the lifting state. The lifting mechanism 14 of Group A rises and then lifts the lifting mechanism 3 in contact with it.

[0069] Step 6: Fix the lifted weight 31 of Group A on the box body 6, close the hydraulic oil circuit reversing valve 142. At this time, release the weight 31 of Group B. The weight 31 of Group B descends under its own gravity and squeezes the liquid 4 in the first chamber 11 of Group B, so that the liquid 4 flows through the telescopic pipe 33 into the water supply pipe 2 and then flows to the water inlet pipe 13 of the liquid driving mechanism 1 of Group A. The liquid 4 enters the second chamber 12 of Group A through the water inlet pipe 13 to drive the power generation mechanism 7 to work.

[0070] Through the above steps, the state switching of the two liquid driving mechanisms 1 is achieved, and the liquid 4 circulates between the two liquid driving mechanisms 1 and the water supply pipeline 2, enabling the power generation mechanism 7 to continuously operate.

[0071] This recycling of energy enables the system to continuously operate without additional power and generate electrical energy continuously. By providing a connecting pipe 141 between the two lifting mechanisms 14, the circulating liquid power generation device can achieve the linkage of the lifting mechanisms 14, reduce the demand for additional power, improve the stability and reliability of the system, optimize energy utilization, and achieve the automated operation of the system. This design enables the entire system to continuously and efficiently operate without additional power, with significant economic and environmental benefits. It effectively avoids some defects and deficiencies of traditional hydropower generation, is not affected by dry seasons, and well meets the demand for large power generation.

[0072] Further, the electrical energy generated by the operation of the power generation mechanism 7 can supply power to the driving member 52.

[0073] Further, the lifting fluid can be hydraulic oil, lubricating oil, transmission oil, etc.

[0074] Further, when the driving member 52 is set as a cylinder, the driving member 52 will continuously generate gas during the driving process. The accumulation of gas may cause air resistance, affecting the normal operation of the cylinder. To discharge the gas generated by the driving member 52, the box body 6 located at the lifting mechanism 14 is provided with a breathing port 62, and the gas is discharged through the breathing port 62, which can effectively avoid air resistance, ensure the driving efficiency of the cylinder, achieve pressure relief, and ensure the balance of the air pressure inside and outside the box body 6.

[0075] Further, as Figure 7 shown, since the two lifting mechanisms 14 are connected through the connecting pipe 141, in order to transfer all the pressure changes on one side to the other side and achieve one-way flow, a hydraulic oil circuit reversing valve 142 is provided to achieve the one-way flow of the lifting fluid. When the lifting mechanism 14 of group A descends, the lifting fluid of the lifting member 144 of group A flows from the connecting pipe 141 into the lifting mechanism 14 of group B, pushing the lower piston plate of the lifting mechanism 14 to rise, and then lifting the heavy object 31 of group B. By providing the hydraulic oil circuit reversing valve 142, it ensures the one-way flow of the lifting fluid and controls the opening and closing time period, improving the control accuracy of the system. This design can effectively utilize the limited liquid 4 resources and achieve efficient energy conversion and recycling.

[0076] Specifically, as Figures 8-9As shown, the water supply pipe 2 includes a pressure pipe 21 and a drain pipe 22. The power generation mechanism 7 is arranged between the pressure pipe 21 and the drain pipe 22. During use, the pressure pipe 21 is responsible for guiding the liquid 4 from a liquid driving mechanism 1 to the power generation mechanism 7, and the drain pipe 22 is responsible for guiding the liquid 4 from the power generation mechanism 7 to another liquid driving mechanism 1. By arranging the power generation mechanism 7 between the pressure pipe 21 and the drain pipe 22, the kinetic energy and potential energy of the liquid 4 can be fully utilized. When the liquid 4 passes through the power generation mechanism 7, it drives the water wheel or turbine to rotate, thereby driving the generator to generate electricity. This layout ensures that the energy of the liquid 4 is maximally converted into electrical energy before entering the next liquid driving mechanism 1. At the same time, the design of the pressure pipe 21 and the drain pipe 22 helps to balance the pressure in the system, preventing equipment damage or unstable operation caused by pressure fluctuations. Moreover, by reasonably designing the pipe diameters and lengths of the pressure pipe 21 and the drain pipe 22, the speed and flow rate of the liquid 4 can be controlled to ensure that the power generation mechanism 7 operates under optimal conditions.

[0077] Furthermore, arranging the power generation mechanism 7 between the pressure pipe 21 and the drain pipe 22 facilitates the maintenance and repair of the power generation mechanism 7. When needed, the power generation mechanism 7 can be separately disassembled and replaced without large-scale modification of the entire water supply pipe 2. This layout reduces the direct interference of the power generation mechanism 7 on the liquid driving mechanism 1 and improves the overall operating efficiency of the system.

[0078] Furthermore, the pressure pipe 21 includes a main pipe one 211, a sub-pipe one 212, and a sub-pipe two 213. One end of the main pipe one 211 is respectively connected to the sub-pipe one 212 and the sub-pipe two 213. The other end of the sub-pipe one 212 is connected to the telescopic pipe 33 of one of the liquid driving mechanisms 1, and the other end of the sub-pipe two 213 is connected to the telescopic pipe 33 of the other liquid driving mechanism 1. During use, the sub-pipe one 212 and the sub-pipe two 213 are respectively connected to the telescopic pipes 33 of the two liquid driving mechanisms 1 and are responsible for guiding the liquid 4 discharged from each liquid driving mechanism 1 to the main pipe one 211. In order to flexibly control the flow direction of the liquid 4 from which liquid driving mechanism 1 to the power generation mechanism 7, a control valve one 214 is provided at the connection of the main pipe one 211, the sub-pipe one 212, and the sub-pipe two 213.

[0079] Furthermore, the drain pipe 22 includes a main pipe two 221, a sub-pipe three 222, and a sub-pipe four 223. One end of the main pipe two 221 is respectively communicated with the sub-pipe three 222 and the sub-pipe four 223. The other end of the sub-pipe three 222 is communicated with the water inlet pipe 13 of one of the liquid driving mechanisms 1, and the other end of the sub-pipe four 223 is communicated with the water inlet pipe 13 of the other liquid driving mechanism 1. Wherein, a control valve two 224 is provided at the connection of the main pipe two 221, the sub-pipe three 222, and the sub-pipe four 223. When it is necessary to switch the liquid 4 target, the control valve two 224 can close the liquid 4 flowing to one side and open the liquid 4 flowing to the other side at the same time.

[0080] The working principle of the present invention will be described in detail below;

[0081] First, one liquid driving mechanism 1 is in Group A and another liquid driving mechanism 1 is in Group B. At this time, the lifting mechanism 14 of the liquid driving mechanism 1 in Group A is in the lifting state, and the lifting mechanism 14 of the liquid driving mechanism 1 in Group B is in the compressed state. Fix the heavy object 31 in Group A to the box body 6 and close the hydraulic oil circuit reversing valve 142. Inject the liquid 4 into the second chamber 12 in Group A. The liquid 4 in the second chamber 12 in Group A naturally flows through the connection hole 322 into the first chamber 11 in Group A. The lifting mechanism 14 in Group A changes from the lifting state to the compressed state under the self-gravity of the liquid 4. The lifting fluid in the lifting mechanism 14 in Group A gradually flows through the communicating pipe 141 to the lifting mechanism 14 in Group B; the lifting mechanism 14 in Group B gradually obtains the lifting fluid from the lifting mechanism 14 in Group A, so that the lifting mechanism 14 in Group B gradually changes from the compressed state to the lifting state, and the lifting mechanism 14 in Group B rises and then lifts the lifting mechanism 3 in contact with it; Fix the lifted heavy object 31 in Group B to the box body 6 and close the hydraulic oil circuit reversing valve 142. At this time, release the heavy object 31 in Group A. The heavy object 31 in Group A descends under its own gravity and squeezes the liquid 4 in the first chamber 11 in Group A, so that the liquid 4 flows into the water supply pipe 2 through the telescopic pipe 33 and then flows to the water inlet pipe 13 of the liquid driving mechanism 1 in Group B. The liquid 4 enters the second chamber 12 in Group B through the water inlet pipe 13 to drive the power generation mechanism 7 to work; The liquid 4 in the second chamber 12 in Group B naturally flows into the first chamber 11 in Group B. Open the hydraulic oil circuit reversing valve 142. The liquid 4 in the first chamber 11 in Group B changes the lifting mechanism 14 in the lifting state in Group B to the compressed state under its own gravity. The lifting fluid in the lifting mechanism 14 in Group B gradually flows through the communicating pipe 141 to the lifting mechanism 14 in Group A. The lifting mechanism 14 in Group A gradually obtains the lifting fluid from the lifting mechanism 14 in Group B, so that the lifting mechanism 14 in Group A gradually changes from the compressed state to the lifting state, and the lifting mechanism 14 in Group A rises and then lifts the lifting mechanism 3 in contact with it; Fix the lifted heavy object 31 in Group A to the box body 6 and close the hydraulic oil circuit reversing valve 142. At this time, release the heavy object 31 in Group B. The heavy object 31 in Group B descends under its own gravity and squeezes the liquid 4 in the first chamber 11 in Group B, so that the liquid 4 flows into the water supply pipe 2 through the telescopic pipe 33 and then flows to the water inlet pipe 13 of the liquid driving mechanism 1 in Group A. The liquid 4 enters the second chamber 12 in Group A through the water inlet pipe 13 to drive the power generation mechanism 7 to work; Through the above steps, the state switching of the two liquid driving mechanisms 1 and the circulating flow of the liquid 4 between the two liquid driving mechanisms 1 and the water supply pipe 2 are realized, so that the power generation mechanism 7 works continuously.

[0082] The innovation of the present invention lies in that two liquid driving mechanisms are linked through a connecting pipe, reducing the demand for additional power, realizing the circulating flow of water liquid in the system, forming a water circulation system, achieving the automatic operation of the system and the recycling of energy, and maximizing the utilization of the energy of water liquid; at the same time, a power generation mechanism is arranged in the water supply pipeline to convert the kinetic energy and gravitational potential energy of water liquid into electric energy, improving the energy utilization efficiency.
