Description

Technical Field

[0001] This invention relates to the field of power generation technology, and in particular to a pumped storage power generation device for inland lakes and nearshore sea areas. Background Technology

[0002] With the transformation of the global energy structure, the proportion of new energy installed capacity in the power grid is increasing. However, the intermittency and instability of new energy power generation pose a huge challenge to the rapid peak shaving of the power grid. Existing hydroelectric generating units and pumped storage generating units, as important means of energy storage and peak shaving, often require the simultaneous planning of upstream and downstream reservoirs and dams during construction. This not only requires a large land area but is also severely limited by terrain conditions, making it difficult to meet the ever-increasing peak shaving needs of the power grid.

[0003] Given the above, exploring new energy storage and peak-shaving technologies is particularly urgent. Considering the widespread distribution and availability of natural water bodies such as lakes and nearshore seas, utilizing these water bodies for hydropower generation and pumped storage becomes a feasible solution. Specifically, by constructing hydroelectric generator units in these natural water bodies, during peak periods of new energy power generation and when grid peak-shaving is difficult, pumps can be started to pump water into upper storage tanks for storage, converting electrical energy into the potential energy of the water for storage. When the grid load is insufficient, the water in the storage tanks can be released to generate electricity through turbine units, converting the stored potential energy into electrical energy, thereby compensating for the insufficient grid load. However, the water inlet of the turbine generator cannot be adjusted according to the flow velocity of the liquid in the storage tank, and the water flow velocity depends on the turbine's power generation efficiency; a reasonable flow velocity can improve the turbine's power generation efficiency.

[0040] Example 1

[0041] Reference Figures 1-3 This is the first embodiment of the present invention. This embodiment provides a pumped storage power generation device for land lakes and nearshore sea areas. It includes a water storage tank 101 in which water is directly discharged, which generates an impact force to make the rotor 201 rotate. The rotating rotor 201 generates electrical energy, thereby reducing the pressure on the power grid.

[0042] Specifically, the power generation component 100 includes a water storage tank 101, a support column 102 set at the bottom of the water storage tank 101, a water turbine generator 103 set on the side wall of the support column 102, and a water pump 104 set on the side wall of the water turbine generator 103.

[0043] Furthermore, the connecting assembly 200 includes a runner 201 disposed inside the housing of the hydro-generator 103, a speed regulating ring 202 at the bottom of the runner 201, and a fixed shaft 203 disposed at the bottom of the speed regulating ring 202.

[0044] Furthermore, the power generation assembly 100 also includes a water pump pipe 105 disposed at the end of the water pump 104, the bottom end of the water pump pipe 105 extending to the water source, and the top end of the water pump 104 is provided with a water outlet pipe 106, the end of the water outlet pipe 106 away from the water pump 104 being connected to the water storage tank 101.

[0045] Operation process: During peak electricity usage periods, the device opens the water valve in the water storage tank 101, allowing water in the tank to move downwards under its own gravity, passing through the conveying chamber 301c and entering the turbine 201. The impact force of the water flow drives the turbine 201 to rotate, converting water energy into electrical energy to reduce grid pressure. Since the water flow speed varies due to different inlet diameters, to maintain power generation stability, the diameter of the conveying chamber 301c of the turbine generator 103 needs to be adjusted according to the actual water output of the water storage tank 101. By activating the hydraulic cylinder 301d, the inlet 301a moves downwards, causing the adjusting cylinder 301b to contract, thereby adjusting the diameter of the conveying chamber 301c so that the diameter can be adjusted according to the water flow speed. During off-peak periods, the water pump 104 pumps water from the water source into the water storage tank 101 for storage and use in peak power generation.

[0046] Example 2

[0047] Reference Figures 4-5 and Figures 7-8 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the driving component 301 is used to drive the adjusting component 302 to move, thereby adjusting the water flow speed through the moving adjusting component 302. At the same time, the adjusting component 302 can also clean the inner wall deposits and improve the pipeline's transport efficiency.

[0048] Specifically, the adjustment component 300 includes a drive component 301 disposed on the side wall of the hydro-generator 103, an adjustment component 302 disposed at the top of the drive component 301, and a buffer component 303 mounted at the top of the drive component 301.

[0049] Furthermore, the drive component 301 includes a water inlet 301a disposed at the top of the housing of the water turbine generator 103, an adjusting cylinder 301b disposed at the bottom end of the water inlet 301a, and a conveying cavity 301c formed between the adjusting cylinder 301b and the water inlet 301a.

[0050] Furthermore, the drive unit 301 also includes a hydraulic cylinder 301d disposed on the side wall of the hydro generator 103, the piston rod end of the hydraulic cylinder 301d extending to the piston chamber 301e and connected to the housing of the delivery chamber 301c.

[0051] Furthermore, the drive unit 301 also includes a first magnetic stone 301f disposed inside the piston cavity 301e, and the top end of the adjusting cylinder 301b extends to the piston cavity 301e and is connected to the first magnetic stone 301f.

[0052] Furthermore, the drive unit 301 also includes a fixing ring 301g disposed on the inner wall of the conveying cavity 301c. A connecting ring 301h is installed on the side wall of the fixing ring 301g. A cavity 301i is disposed inside the connecting ring 301h. An airbag 301j is disposed inside the cavity 301i. A push rod 301k is installed on the side wall of the airbag 301j.

[0053] Furthermore, the drive unit 301 also includes a sealing plug 301m disposed at the junction of the push rod 301k and the connecting ring 301h. The end of the push rod 301k away from the airbag 301j is connected to the scraper 301n, and the end of the scraper 301n away from the push rod 301k is equipped with a second magnetic stone 301p.

[0054] The rest of the structure is the same as in Example 1.

[0055] Operation process: During peak electricity usage periods, the device opens the water valve in the storage tank 101, allowing water in the tank to move downwards under its own weight, passing through the conveying chamber 301c and entering the turbine 201. The impact force of the water flow drives the turbine 201 to rotate, converting water energy into electrical energy to reduce grid pressure. Since the water flow speed varies depending on the inlet diameter, to maintain power generation stability, the diameter of the conveying chamber 301c of the turbine generator 103 needs to be adjusted according to the actual water output from the storage tank 101. By activating the hydraulic cylinder 301d, the inlet 301a moves downwards. The inlet 301a contracts the adjusting cylinder 301b to adjust the diameter of the conveying chamber 301c, allowing the diameter to be adjusted according to the water flow velocity. When the conveying chamber 301c is covered by algae and impurities in the water, it can easily reduce the water flow velocity, thereby affecting the power generation efficiency of the turbine generator 103. Therefore, the downward-moving inlet 301a causes the first magnetic stone 301f to slide in the piston chamber 301e. Since the first magnetic stone 301f and the second magnetic stone 301p attract each other, the scraper 301n of the inlet 301a scrapes and cleans the impurities or algae on the inner wall of the conveying chamber 301c during the downward movement, which can effectively improve the conveying efficiency of the pipeline.

[0056] Example 3

[0057] Reference Figures 2-3 and Figures 5-6This is the third embodiment of the present invention. The difference between this embodiment and the previous embodiments is that the adjusting member 302 can defoam, and the bubbles will reduce the flow rate of the water. Reducing the amount of bubbles can effectively improve the water flow delivery efficiency.

[0058] Specifically, the adjusting component 302 includes a rotating shaft 302a disposed at the top of the fixed ring 301g, a fixed cylinder 302b disposed on the side wall of the rotating shaft 302a, a reverse bushing 302c disposed at the end of the fixed cylinder 302b, and a connecting cylinder 302d installed on the side wall of the reverse bushing 302c.

[0059] Furthermore, the adjusting component 302 also includes a connecting rod 302e disposed on the side wall of the connecting cylinder 302d, an adjusting plate 302f disposed on the side wall of the rotating shaft 302a, and a telescopic cylinder 302g disposed on the side wall of one of the fixed cylinders 302b.

[0060] Furthermore, the buffer 303 includes an adjusting blade 303a disposed on the side wall of the housing of the hydro-generator 103. A first connecting rod 303b is hinged to the outer wall of the adjusting blade 303a. A second connecting rod 303c is hinged to the end of the first connecting rod 303b. An annular body 303d is installed at the end of the second connecting rod 303c. A spring piece 303e is disposed on the housing of the hydro-generator 103. The annular body 303d is sleeved on the side wall of the spring piece 303e.

[0061] The rest of the structure is the same as in Example 2.

[0062] Operation process: During peak electricity usage periods, the device opens the water valve in the storage tank 101, allowing water in the storage tank 101 to move downwards under its own gravity, passing through the conveying chamber 301c and entering the turbine 201. The impact force of the water flow drives the turbine 201 to rotate, converting water energy into electrical energy to reduce grid pressure. Since the water flow speed varies depending on the inlet diameter, to maintain power generation stability, the diameter of the conveying chamber 301c of the turbine generator 103 needs to be adjusted according to the actual water output from the storage tank 101. By activating the hydraulic cylinder 301d, the inlet 301a moves downwards, causing the inlet 301a to move downwards. The adjusting cylinder 301b contracts to adjust the diameter of the conveying chamber 301c, allowing the diameter to be adjusted according to the water flow velocity. When the conveying chamber 301c is covered by algae and impurities in the water, it can easily reduce the water flow velocity, thus affecting the power generation efficiency of the turbine generator 103. Therefore, the downward-moving inlet 301a causes the first magnetic stone 301f to slide in the piston chamber 301e. Due to the attraction between the first magnetic stone 301f and the second magnetic stone 301p, the scraper 301n of the inlet 301a scrapes and cleans the impurities or algae on the inner wall of the conveying chamber 301c during the downward movement. The scraper 301n can be adjusted according to the size of the conveying chamber 301c. When the conveying chamber 301c decreases in size, it squeezes the scraper 301n, causing the push rod 301k to squeeze the airbag 301j. When the squeezing force is insufficient, the pressure in the airbag 301j pushes out the push rod 301k and activates the telescopic cylinder 302g. The telescopic cylinder 302g drives the connecting rod 302e to deflect, which in turn drives the adjusting plate 302f on the rotating shaft 302a to move. The rotating shaft 302a drives the reverse bushing 302c to rotate, which in turn drives another connecting rod 302e to rotate in the opposite direction, causing all the adjusting plates 302f to deflect, thus enabling the... The water at the inlet undergoes defoaming treatment. When the water flows out of the turbine generator 103, different numbers of bubbles are generated due to the flow rate. These bubbles affect the arc-shaped cone at the bottom of the fixed shaft 203. Therefore, different water flow impact forces cause the adjusting blade 303a to produce different curvatures. The water flow impact force causes the adjusting blade 303a to deflect. The deflected adjusting blade 303a causes the first connecting rod 303b and the second connecting rod 303c to deflect. The deflected first connecting rod 303b and the second connecting rod 303c cause the ring body 303d to squeeze the spring piece 303e. When there is no water pressure impact force, the elastic force of the spring piece 303e causes the adjusting blade 303a to return to its original position.
