Description

Technical Field

[0002] Renewable energy generation is widely used due to its environmental friendliness and strong sustainability. Currently, wind power generation and hydropower generation are widely used types of renewable energy generation.

[0003] For wind power generation, a dedicated wind turbine is usually used. The wind turbine is too large and generally has several (mostly 3) blades installed on a bracket to drive the internally installed power generation rotor 27 to rotate and generate electricity. The longer blades occupy a larger space, affecting the environmental conditions of the space, especially posing a greater risk of harm to birds. In addition, the longer blades bring about a larger blade vibration amplitude, generate greater noise, and have a negative impact on surrounding production activities. Moreover, since it is difficult for the blades to adapt to changes in wind direction, the force fluctuates greatly, and the generated electricity also fluctuates synchronously, resulting in unstable power generation.

[0004] For hydropower generation, a water storage and release mode is generally used to achieve power generation. The stored water forms a certain head, and when the water is released, kinetic energy is generated to drive the turbine rotor to generate electricity. Although hydropower generation can adjust the power generation to meet the needs of the power grid, the power generation facilities have shortcomings such as large footprint, relatively high cost, long construction period, and large social and environmental impact.

DETAILED DESCRIPTION

[0029] The present invention will be further described in detail below in conjunction with specific implementations and with reference to the accompanying drawings. It should be emphasized that the following description is merely exemplary and is not intended to limit the scope of the present invention and its application.

[0030] Embodiment 1:

[0031] This embodiment provides a damping power generation device 1, such as Figure 2-3 As shown, the power generation device includes a shell 11, a fluid inlet 12 is provided on one side of the shell 11, and a fluid energy conversion mechanism and a generator assembly 15 are provided in the shell 11, the fluid energy conversion mechanism is arranged on the side close to the fluid inlet 12, and the fluid energy conversion mechanism includes a first radial guide assembly and a first moving blade assembly, the first radial guide assembly is coaxially arranged with the fluid inlet 12 to radially guide the axial fluid, the first moving blade assembly is rotatably arranged on the radial outer periphery of the first radial guide assembly and is connected to the rotor shaft of the generator assembly 15, that is, the first moving blade assembly is arranged in the radial direction of the first radial guide assembly, so that the radial fluid guided by the first radial guide assembly can be used to drive the first moving blade assembly to rotate, and then the rotor shaft of the generator is driven to rotate through the first moving blade assembly to generate electricity.

[0032] The size of the housing 11 is determined according to the actual use environment. In this embodiment, the size of the housing 11 is preferably 22000*22000*6000 (mm). The power generation capacity of the generator assembly 15 is also determined according to the actual environment. In this embodiment, it is preferably 880kw.

[0033] In this embodiment, the fluid inlet 12 on the shell 11 can be used as both an inlet and an outlet in actual use. Of course, in order to ensure that the fluid enters the generator assembly 15 at an optimal angle and speed, it can be understood that a fluid outlet can be provided on the shell 11 to discharge the waste fluid after the energy conversion is completed. The fluid outlet can be provided at the top or rear of the shell 11 so as to discharge the waste fluid as quickly as possible to avoid the formation of positive pressure in the shell 11.

[0034] The damping power generation device 1 uses fluid energy as a power source, wherein the fluid energy mainly includes water energy and wind energy, that is, the device is compatible with wind power generation and hydropower generation and has a wide range of uses. In addition, the power generation device of this structure is more compact than the equipment used for traditional wind power generation and hydropower generation, and the blades are built into the shell 11, which improves the safety of use and reduces the impact on the environment. Especially for hydropower generation, only water flow is required, and there is no need to store water, which not only improves the safety of use, but also reduces the floor space, construction scale and cost.

[0035] The first radial flow guide component includes a conical flow guide 131 and a flow guide fixed blade 132. As the name implies, the conical flow guide 131 should be used to guide the fluid. Therefore, it can be understood that the top of the cone of the conical flow guide 131 should face the fluid inlet 12, and the bottom of the cone is preferably a cylindrical structure; the conical flow guide 131 is fixed at the axial center position of the shell 11, that is, located at the center position of the inner cavity of the shell 11, and the flow guide fixed blade 132 includes a plurality of groups, which are equidistant and axially arranged on the radial periphery of the conical flow guide 131, and a diversion channel is formed between two adjacent flow guide fixed blades 132; the flow guide fixed blade 132 can be a quadrilateral straight plate or an arc plate, and the specific basis is According to actual needs, the present embodiment preferably adopts a rectangular straight plate structure, which is connected to the columnar structure at the bottom end of the cone of the conical guide 131. Of course, it can also be directly fixed on the outer wall of the cone of the conical guide 131 if necessary; the fluid enters the fluid inlet 12 axially, and under the action of the conical guide 131 and multiple guide vanes 132, the flow direction of the fluid can be changed. Specifically, the fluid entering axially is guided radially through the conical guide 131 and the diversion channel. The radially flowing fluid can contact the first moving blade assembly arranged radially outside the conical guide 131 and drive it to rotate, thereby driving the rotor shaft of the generator assembly 15 to rotate to achieve power generation.

[0036] The first moving blade assembly includes a linkage roller 141 and moving blades 142. The linkage roller 141 can be a closed drum structure, so that the fluid can be converged to increase the contact area between the fluid and the moving blades 142. At the same time, the kinetic energy loss of the fluid can be reduced, thereby maximizing the utilization of the kinetic energy of the fluid; the linkage roller 141 is sleeved on the outside of the conical guide vane 131 through the first bearing seat 19, and the moving blades 142 include multiple groups, which are equidistant and axially arranged on the inner wall of the linkage roller 141, and each moving blade 142 is inclined relative to the inner wall of the linkage roller 141. It can be understood that the inclination angle is selected according to actual needs. In this embodiment, the inclination angle of the moving blade 142 relative to the inner wall of the linkage roller 141 is preferably between 15° and 45°. The inclination angle can ensure that the moving blade 142 can maximize the contact with the radially flowing fluid, and the radially flowing fluid guided by the diversion channel can contact the front of the moving blade 142 and drive the linkage roller 141 to rotate relative to the conical guide vane 131.

[0037] like Figure 2 As shown, it is a schematic diagram of the relative position structure of the guide stator blades 132 and the moving blades 142 provided in this embodiment. In this structure, the guide stator blades 132 are also inclined relative to the outer surface of the conical guide 131. The inclined guide stator blades 132 and the moving blades 142 are arranged relative to each other and are orthogonal or obtusely angled, preferably orthogonal. This configuration, combined with the effect of the first radial guide assembly on the radial guidance of the axial fluid, can effectively enhance the flow dynamics of the fluid and its contact area with the first moving blade assembly, thereby significantly improving the power generation efficiency.

[0038] A sunken arc-shaped guide cover 18 is provided at the fluid inlet 12. The arc-shaped guide cover 18 is preferably a comb-tooth structure, which is convenient for discharging the fluid after energy conversion. One side of the arc-shaped guide cover 18 is fixed to the edge of the fluid inlet 12, that is, the shell 11, and the other side is connected to the guide vanes 132 in the first radial guide assembly to form a fluid cavity. The arc-shaped guide cover 18 can better introduce the fluid into the fluid cavity and change the flow direction in the fluid cavity through the first radial guide assembly. Since the fluid cavity realizes the convergence of the fluid, changing the flow direction by the conical guide 131 and the guide vanes 132 can effectively increase the flow velocity and pressure of the fluid, thereby increasing its kinetic energy relative to the moving blades 142.

[0039] An orientation adjustment mechanism is provided on the outside of the housing 11, and the orientation adjustment mechanism includes an adjustment plate 16 and a rotating base 17 with a self-rotating mechanism. The adjustment plate 16 is arranged along the axial direction of the housing 11 and is located above the housing 11, and is used to contact the fluid and cooperate with the rotating base 17 to adjust the orientation of the housing 11, ensuring that the fluid inlet 12 faces the flow direction of the fluid as much as possible, thereby increasing the fluid intake. The self-rotating mechanism is preferably an existing conventional structure, mainly including a rotating part, a guiding part and a supporting part. The fluid is used as a power source, and the rotating base 17 is driven by the power source to rotate and adjust the orientation of the housing 11.

[0040] A brake unit 10 is provided on the fluid energy conversion mechanism, and the brake unit 10 is used to control the start and stop of the fluid energy conversion mechanism. In this embodiment, the brake unit 10 is an existing conventional brake, which mainly includes structures such as a clutch, a motor and a gear. It is connected to the linkage roller 141 to complete the comprehensive safety and status detection of the device. After meeting the starting conditions, the brake unit 10 can be removed to enter the device starting state, otherwise it remains in a locked state, thereby improving the safety of use.

[0041] In summary, the present embodiment adopts a damping method to generate electricity. The blades of the power generation device are built-in and have no external moving parts, which is safer for the environment and organisms. At the same time, the vibration noise generated is constrained by the shell 11 and will not cause noise pollution. In addition, the axial airflow and radial guidance are adopted to increase the airflow contact area, and can change in square level as the product size increases, thereby improving the power generation efficiency. Compared with traditional wind power generation equipment or hydropower generation equipment occupying the same space height, the power generation capacity can be increased by more than 20 times (the blade width is calculated as 10% of the length on average, and if calculated as 5%, the multiple is more than 40 times). In the present embodiment, all parts of the damping power generation device 1 can be made of metal materials, which can be completely recycled and have no hidden dangers of environmental protection treatment.

[0042] Embodiment 2:

[0043] This embodiment provides a steam power generation device 2, such as Figure 3-4As shown, the power generation device includes a casing 21, in which a power generation stator 26 and a power generation rotor 27 are arranged. It can be understood that the power generation stator 26 and the power generation rotor 27 are used to generate electric energy, and their structures should be the same as the power generation structure and principle inside the existing conventional generator. The difference is that their structure should be adapted to the inner cavity of the casing 21 of the power generation device, and the power generation stator 26 is in contact with and fixedly connected to the inner wall of the casing 21. The power generation rotor 27 is rotatably sleeved in the power generation stator 26 through the second bearing seat 20. At the same time, the power generation rotor 27 is provided with an axial hole for fixing the rotor shaft; the casing 21 is also provided with a rotor shaft composed of a second moving blade assembly and a second radial guide assembly, that is, the embodiment adopts the second moving blade assembly and the first The structure formed by the two radial guide assemblies replaces the rotor shaft in the traditional generator structure. The second moving blade assembly is an annular structure, which is coaxial with the axial hole of the power generation rotor 27 and fixedly connected. The second radial guide assembly is sleeved in the second moving blade assembly and its two ends pass through the casing 21 to form a low-pressure steam outlet 24 and a high-pressure steam inlet 25 on the casing 21. The second radial guide assembly is used to radially guide the axial high-pressure steam entering through the high-pressure steam inlet 25. In this embodiment, the second moving blade assembly is arranged on the radial outer periphery of the second radial guide assembly. Therefore, the high-pressure steam radially guided by the second radial guide assembly can contact the second moving blade assembly and drive it to rotate, and the low-pressure steam is discharged through the low-pressure steam outlet 24.

[0044] The size of the housing 11 is determined according to the actual use environment. In this embodiment, the preferred size of the housing 21 is 22000*22000*6000 (mm).

[0045] The device uses high-pressure steam as power, and the source of high-pressure steam can be a boiler or other steam system, which realizes the effective use of steam energy. In addition, the steam power generation device 2 adopts a structure composed of a second moving blade assembly and a second radial guide assembly to replace the rotor shaft in the traditional generator structure, which not only simplifies the traditional steam turbine structure (the transmission shaft of the rotating steam turbine is connected to the rotor shaft of the generator), increases the compactness of the structure, reduces the floor space, and can enhance the power generation efficiency. Specifically, the radial guidance of the axial high-pressure steam by the second radial guide assembly increases the flow rate and air pressure of the high-pressure steam, thereby enhancing the driving force of the high-pressure steam on the second moving blade assembly, and increasing the speed at which the second moving blade assembly drives the power generation rotor 27 to rotate; at the same time, compared with the existing intermittent renewable natural energy, due to the controllability of parameters such as air pressure, flow rate, and flow rate of high-pressure steam, the power generation device can output electric energy with more stable phase, voltage, and frequency, meeting the needs of direct access to the grid.

[0046] The second radial flow guide component includes a conical flow guide 22 and a diverter vane 23. As the name implies, the conical flow guide 22 should be used to guide the fluid. Therefore, it can be understood that the top of the cone of the conical flow guide 22 should face the high-pressure steam inlet 25, and the bottom of the cone is preferably a cylindrical structure; the conical flow guide 22 is fixed on the casing 21 and is coaxial with the axial hole of the power generation rotor 27; the diverter vane 23 includes a plurality of groups, which are equidistant and axially arranged on the outer periphery of the conical flow guide 22, and a diverter channel is formed between two adjacent diverter vanes 23. The diverter vane 23 can be a quadrilateral straight plate or an arc plate, which can be selected according to actual needs. The preferred embodiment is a trapezoidal straight plate structure that is wider at the top and narrower at the bottom, which is connected to the columnar structure at the bottom end of the cone of the conical deflector 22. Of course, it can also be directly fixed on the outer wall of the cone of the conical deflector 22 if necessary; high-pressure steam enters the steam inlet axially, and under the action of the conical deflector and multiple diverter blades 23, the flow direction of the high-pressure steam can be changed. Specifically, the high-pressure steam entering axially is guided radially through the conical deflector 22 and the diverter channel. The radially flowing high-pressure steam can contact the second moving blade assembly arranged on the radial outside of the conical deflector 22 and drive it to rotate, thereby driving the power generation rotor 27 to rotate to achieve power generation.

[0047] The second moving blade assembly only includes transmission blades 28, and the transmission blades 28 include multiple groups, which are equidistant and axially arranged on the inner wall of the shaft hole of the power generation rotor 27. The transmission blades 28 can be fixed to the inner wall of the shaft hole by welding. Of course, other possible and reasonable fixing methods also fall within the protection scope of this embodiment. Each transmission blade 28 is inclined relative to the inner wall of the shaft hole. It can be understood that the inclination angle is selected according to actual needs. In this embodiment, the preferred inclination angle of the moving blades 142 relative to the inner wall of the shaft hole is between 15°-45°. This inclination angle can increase the contact area between the transmission blades 28 and the radially flowing high-pressure steam.

[0048] Alternatively, the second moving blade assembly includes a rotating roller and a transmission blade 28. The rotating roller is fixed on the inner wall of the shaft hole of the power generation rotor 27 and is sleeved on the outside of the conical deflector 22 through the second bearing seat 20. In this structure, the rotating roller serves as an intermediate connecting piece between the transmission blade 28 and the shaft hole. The rotating roller can be connected to the inner wall of the shaft hole by pinning or welding. The transmission blade 28 includes a plurality of groups, which are equidistantly and axially welded on the inner wall of the rotating roller, and each transmission blade 28 is inclined relative to the inner wall of the rotating roller. The preferred inclination angle of this embodiment is also between 15° and 45°.

[0049] In this embodiment, the inclined transmission blades 28 are arranged opposite to the diverter stator blades 23 and are arranged at an orthogonal or obtuse angle. The radially flowing steam guided by the diverter channel can contact the front of the transmission blades 28 and thereby drive the power generation rotor 27 to rotate; it can be understood that in order to meet the required orthogonal or obtuse angle arrangement requirements, the diverter stator blades 23 should also be inclined relative to the outer surface of the conical guide vane 22, and the specific inclination angle can be adjusted according to the required arrangement angle of the transmission blades 28 and the diverter stator blades.

[0050] like Figure 4 As shown, it is a schematic diagram of the relative position structure of the splitter stator blades 23 and the transmission blades 28 provided in this embodiment. In this structure, the splitter stator blades 23 are also inclined relative to the outer surface of the conical guide vane 22. The inclined splitter stator blades 23 and the transmission blades 28 are arranged relative to each other and are orthogonal or obtusely arranged, preferably orthogonal. This configuration combined with the radial guidance of the axial high-pressure steam by the second radial guide assembly can effectively enhance the flow dynamics of the high-pressure steam and its contact area with the second moving blade assembly, thereby significantly improving the power generation efficiency.

[0051] A support base 29 is preferably provided at the bottom of the housing 21 to facilitate fixing and installation.

[0076] In summary, the system of this embodiment is not only compatible with wind power generation and hydropower generation and has a wide range of uses, but can also convert unstable primary electric energy generated by wind energy or hydropower into stable secondary electric energy, thereby improving the quality of electric power and facilitating direct access to the grid.

[0077] This embodiment uses water energy as a power source to specifically illustrate the specific use of the system in this embodiment:

[0078] Before starting, safety and status checks are performed on each device in the system. At the same time, the required amount of water is injected into the water-steam conversion tank 3 and the steam-water mixing tank 4. After the detection is met, the brake unit 10 set on the damping power generation device 1 is removed, and the system enters the starting state. At the same time, the wind inlet direction of the shell 11 of the damping power generation device 1 is automatically adjusted through the adjustment plate 16 in the direction adjustment mechanism and the support base 29 with a self-rotating mechanism, so that natural wind enters the fluid cavity directly.

[0079] After the system is started, natural wind enters the fluid cavity axially, enters the guide vanes 132 under the action of the conical guide 131, and is radially delivered to the force-bearing moving blades 142 along the set angle. The moving blades 142 are connected to the generator assembly 15 through the linkage roller 141, driving the rotor of the generator assembly 15 to operate, thereby achieving initial power generation;

[0080] The generated electricity is sent to the distribution box 6 through the line, and is connected to the heating unit 31 of the water-steam conversion tank 3 through the line. The electric energy is used to heat the heating unit 31 and then the liquid in the water-steam conversion tank 3 is phase-changed and converted into high-pressure power gas. The high-pressure power gas is controlled by the system and is axially sent into the steam power generation device 2 along the steam transmission pipeline 32 through the pump valve assembly 5 at a certain pressure (such as 10MPa) to drive the power generation rotor 27 to rotate and generate secondary electricity. The generated secondary electricity is output as commercial electricity with stable frequency, phase and voltage through the power distribution station 7.

[0081] The waste heat steam and water from power generation is directly sent to the return water-steam conversion tank 3 through the pipeline; or, the waste heat steam and water from power generation is first sent to the steam-water mixing tank 4 through the pipeline, and according to the instruction, the clean water is injected into the steam-water mixing tank 4 through the pump valve assembly 5 and the water replenishment pipeline 43, and the steam and water in the steam-water mixing pipe can also be supplemented to the water-steam conversion tank 3 for recycling through the pump valve assembly 5 and the connecting pipeline 41. If necessary, the pump valve assembly 5 and the hot water output pipeline 42 can output the water vapor.

[0082] As is well known, the heat of vaporization of water at 100°C is 2226 kJ / kg, and it increases with the increase of vaporization pressure. In this embodiment, by converting low-efficiency electricity into the steam kinetic energy of water, the energy storage scale per unit mass is more than 3-4 times that of a battery, and the water can be recycled and replenished. It can be seen that storing energy by means of water phase vaporization and pressurization is the most effective way with high efficiency, no safety risk, and no environmental pollution risk. Moreover, this method not only improves the quality of low-grade electricity and increases its scope of electricity application, but also has high electricity conversion efficiency.

[0083] The above is only an embodiment of the present invention, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several improvements can be made without departing from the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of the claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
