Description

Technical Field

[0001] The present invention relates to the technical field of temperature difference power generation, and in particular to a well-type power generation device based on vertical temperature difference of a mountain and solar energy collection. Background Art

[0002] Solar air thermal collection and high mountain well power generation device is a new energy solution that uses natural geographical characteristics and renewable energy technology to efficiently and sustainably utilize the vertical temperature difference effect of the mountain and solar energy resources to generate electricity;

[0003] There is a device that digs a well in a mountain with a vertical temperature difference, opens a side opening at the foot of the mountain facing south, and is equipped with an efficient solar air collector. This device significantly increases the temperature of the air entering the well, thereby increasing the temperature difference between the foot of the mountain and the top of the mountain, promoting the rising rate of the hot air. As the hot air with a higher temperature at the foot of the mountain naturally rises, it quickly flows to the area with a lower temperature at the top of the mountain. This hot air is guided to the gas turbine engine installed in the well to generate electricity, achieving the engineering goal of efficient power generation.

[0004] When the temperature difference between the top of the mountain and the bottom of the mountain is less than a certain range, the flow of air in the wellbore will be relatively slow. When the airflow passes through the wind turbine, the flow rate will be further slowed down. At this time, it is easy for the airflow to be difficult to circulate quickly, that is, it is difficult to flow out from the top of the mountain. This phenomenon will occur when the temperature difference between the top of the mountain and the bottom of the mountain is not zero. Therefore, the existing device for generating electricity using vertical temperature difference is still insufficient in actual use, and measures to ensure rapid flow of air in the wellbore still need to be improved. Summary of the invention

[0005] The purpose of the present invention is to provide a well-type power generation device based on the vertical temperature difference of the mountain and solar energy collection, which can be automatically adjusted according to external environmental conditions to ensure the rapid circulation of air, thereby solving the problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a well-type power generation device based on the vertical temperature difference of the mountain and solar energy heat collection, further comprising a well opened in the mountain, the bottom of the well being an air inlet, the top of the well being an air outlet, a heat storage device is laid on the ground at the air inlet, a heat absorption device is erected on the ground at the air inlet, a support template is fixedly installed on the inner wall of the well, three generators are respectively fixedly installed in the well through three groups of mounting frames on the support template, and maintenance chambers corresponding to the three generators are opened in the mountain;

[0007] The generator includes a central shaft, twenty-five blades, twenty-five rotating shafts, a current receiving component, and an induction frame. The twenty-five ends are jointly rotatably connected to a power generation coil, and the power generation coil is rotatably connected to the inner wall of the induction frame. The central shaft is rotatably connected to the inner wall of the generator. A regulation component and a locking component for synchronously controlling the deflection states of the twenty-five blades are arranged inside the central shaft;

[0008] The well-type power generation device further includes an environmental monitoring component, a wind direction detection module, a generator regulation module, and a warning module. The wind direction detection module is used to detect the air inlet angle θ and adjust the temperature difference trigger threshold WC accordingly. The generator regulation module is used to evaluate the operating states of the three generators according to environmental data. The warning module is used to analyze the air pressure fluctuation in the well. The regulation component is used to automatically regulate the blades according to the operating states of the generator and the air pressure fluctuation in the well.

[0009] Optionally, the environmental monitoring component includes:

[0010] A first temperature sensor and a second temperature sensor, which are respectively arranged at the air inlet and the air outlet of the well. A wind direction turning mark is arranged at the air inlet on the ground. A flow velocity sensor and a viscometer are arranged at the air inlet of the well. A wind pressure sensor is arranged at the air inlet of the well.

[0011] Optionally, the regulation component includes a vertical toothed plate. The shaft walls of the twenty-five rotating shafts are all rotatably connected to the inner wall of the central shaft. The shaft walls of the twenty-five rotating shafts are respectively fixedly connected to the inner walls of the twenty-five blades. Gear teeth are fixedly connected to the shaft walls of the twenty-five rotating shafts. The gear teeth of the twenty-five gears are all meshed with the gear teeth of the vertical toothed plate. A regulation motor is fixedly connected to the inner wall of the generator. The output end of the regulation motor is fixedly connected to the surface of the toothed ring. A locking component is also included.

[0012] Optionally, the detection process of the wind direction detection module is as follows:

[0013] Taking the radial coincidence direction of the air inlet of the well as the 90° direction;

[0014]

[0015] Where WD represents the wind direction influence level;

[0016] θ represents the air inlet angle, that is, the air inlet angle of the well;

[0017] WC = α×(W 1 -W 2 )

[0018] Where WC represents the temperature difference trigger threshold;

[0019] W 1 is the temperature at the air inlet at the bottom of the mountain;

[0020] W 2 is the temperature at the air outlet at the top of the mountain;

[0021] When WD = 1, it is a high level, indicating that the external wind direction is in a state of superimposing and accelerating the airflow in the shaft. At this time, α takes

[0022] When WD = 2, it is a medium level, indicating that the external wind direction is in a state of only accelerating the airflow in the shaft. At this time, α takes

[0023] When WD = 3, it is a low level, indicating that the external wind direction is in a state of non-accelerating the airflow in the shaft. At this time, α takes 1;

[0024] By detecting the wind direction of the current environment and setting the wind direction influence level, the temperature difference trigger threshold WC is adjusted according to the wind direction influence level. When the actual temperature difference ≥ the temperature difference trigger threshold WC, the regulation component is not started. When the actual temperature difference < the temperature difference trigger threshold WC, the regulation component is started.

[0025] Optionally, the environmental data includes the fluid flow velocity v and the fluid Reynolds number value R e , during the adjustment of the generator adjustment module, the fluid flow velocity v is obtained as follows:

[0026]

[0027] where v is the fluid flow velocity;

[0028] P air is the air pressure;

[0029] ρ air is the air density;

[0030] Set the wind speed threshold of the fluid flow velocity v as V 1 , when the fluid flow velocity v > the wind speed threshold V 1 , it indicates a high wind speed state;

[0031] When the fluid flow velocity v ≤ the wind speed threshold V 1 , it indicates a low wind speed state;

[0032] The fluid Reynolds number value R e is obtained as follows:

[0033]

[0034] where R e is the fluid Reynolds number value;

[0035] v is the flow velocity of the fluid;

[0036] ρ is the density of the fluid;

[0037] μ is the viscosity coefficient;

[0038] d is the length of the shaft;

[0039] Set the Reynolds number value R of the fluid e The Reynolds threshold is R 1 ;

[0040] When R e > R 1 it indicates a high Reynolds number, and at this time, the air flow represents a turbulent state;

[0041] When R e ≤R 1 it indicates a low Reynolds number; at this time, the air flow represents a laminar state;

[0042]

[0043] Among them, A = a, A = b, and A = c respectively represent three fluid states in the shaft;

[0044] When A = a, it is the first level, indicating that the fluid is a turbulent flow with a high flow velocity;

[0045] When A = b, it is the second level, indicating that the fluid is at a low flow velocity;

[0046] When A = c, it is the third level, indicating that the fluid is in a laminar flow with a high flow velocity;

[0047] When in the first level, turn off the generator in the middle position. When in the second level, turn off the two generators in the middle position and near the air outlet. When in the third level, none of the three generators are turned off.

[0048] Optionally, the warning process of the warning module is as follows:

[0049]

[0050] Among them, p(t) is the wind pressure at time point t;

[0051] ρ(t) is the air density at time point t, which changes with temperature and air pressure;

[0052] v(t) is the wind speed at time point t;

[0053] Δp = |p(t) - p(t - 1)|

[0054] Among them, p(t) is the wind pressure at time point t;

[0055] p(t-1) is the wind pressure at time point t-1;

[0056] Δp is the difference in wind pressure between time point t and time point t-1;

[0057] Set the wind pressure threshold value of the wind pressure difference Δp between time point t and time point t-1 as Δp threshold , if the wind pressure threshold value Δp threshold < the wind pressure difference Δp between time point t and time point t-1, it is determined that the wind pressure fluctuation is too large, and the twenty-five blades on the generator may encounter uneven wind pressure, affecting the safe operation. At this time, all three groups of control components operate, so that the blades of the three groups of generators are in a non-working state.

[0058] Optionally, the locking component includes an electromagnet, the electromagnet is embedded in the inner wall of the induction frame, and an iron ring is embedded in the inner wall of the power generation coil.

[0059] Optionally, the material of the blade is a waterproof and corrosion-resistant material, the heat storage method of the heat storage device is pebble heat storage, and the heat absorption method of the heat absorption device is to install a plastic film for heat absorption.

[0060] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0061] First, through the cooperation of structures such as the shaft tunnel, the heat absorption device and the heat storage device, the present invention uses the temperature difference factor generated between the air outlet and the air inlet of the shaft tunnel to drive the generator to generate electricity, so that the device can generate electricity throughout the year, with less energy consumption and high economic return.

[0062] Second, considering that when the temperature difference value between the top of the mountain and the bottom of the mountain is less than a certain range, the air flow in the shaft tunnel will be relatively slow at this time. To avoid the situation that the air flow is difficult to flow out from the air outlet, the present invention passes through the cooperation of structures such as gears, rotating shafts and vertical toothed plates, collects data on the surrounding environment of the device through the environmental monitoring component, and controls the deflection states of the blades on the three groups of generators respectively, so as to avoid the situation that the air flow in the shaft tunnel is difficult to circulate in the form of reducing the air flow resistance.

[0063] Third, the present invention analyzes the collected data in real time through the wind direction detection module to determine the value of the temperature difference trigger threshold for triggering the operation of the control component, so that the air flow resistance reduction control of the device is more accurate and the control is more targeted.

[0064] IV. The present invention comprehensively judges the air flow velocity and Reynolds number in the hoistway, sets three states of the fluid, namely, high-velocity turbulent flow, low-velocity flow, and high-velocity laminar flow, and proposes corresponding operating states of three groups of regulating components according to the three states, so that the regulation measures to avoid the difficult air flow in the hoistway are more targeted and have better precise effects.

[0081] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0082] Embodiment 1:

[0083] Please refer to Figures 1 to 14 , the present invention provides a well-type power generation device based on the vertical temperature difference of the mountain body and solar heat collection, which further includes a shaft 3 opened in the mountain body 2. The bottom of the shaft 3 is the air inlet, and the top of the shaft 3 is the air outlet. A heat storage device 12 is laid on the ground 1 at the air inlet, and a heat absorption device 4 is erected on the ground 1 at the air inlet. Three support templates 5 are fixedly installed on the inner wall of the shaft 3, and three generators 7 are respectively fixedly installed in the shaft 3 through three installation frames 6 on the support template 5. A maintenance cavity 8 corresponding to the three generators 7 is opened in the mountain body 2;

[0084] The generator 7 includes a central axis 701, twenty-five blades 702, twenty-five rotating shafts 703, a current receiving component 706 and an induction frame 705. The ends of the twenty-five rotating shafts 703 are jointly rotatably connected to a power generation coil 704. The power generation coil 704 is rotatably connected to the inner wall of the induction frame 705. The central axis 701 is rotatably connected to the inner wall of the generator 7. A regulation component and a locking component for synchronously controlling the deflection state of the twenty-five blades 702 are arranged in the central axis 701;

[0085] It further includes an environmental monitoring component, a wind direction detection module, a generator regulation module and an early warning module. The wind direction detection module is used to detect the inlet air angle θ and adjust the temperature difference trigger threshold WC accordingly. The generator regulation module is used to evaluate the operating states of the three generators 7 according to environmental data. The early warning module is used to analyze the wind pressure fluctuation in the shaft 3. The regulation component is used to automatically regulate the blades 702 according to the operating states of the generator 7 and the wind pressure fluctuation in the shaft 3;

[0086] The environmental monitoring components include temperature sensor 1 and temperature sensor 2. Temperature sensor 1 and temperature sensor 2 are respectively arranged at the air inlet and outlet of the shaft 3. A wind direction vane is arranged at the air inlet of the ground 1. A flow velocity sensor and a viscometer are arranged at the air inlet of the shaft 3. A wind pressure sensor is arranged at the air inlet of the shaft 3;

[0087] The regulation component includes a vertical toothed plate 10. The shaft walls of the twenty-five rotating shafts 703 are all rotatably connected to the inner wall of the central shaft 701. The shaft walls of the twenty-five rotating shafts 703 are respectively fixedly connected to the inner walls of the twenty-five blades 702. Gear 11 is fixedly connected to the shaft wall of each of the twenty-five rotating shafts 703. The teeth of the twenty-five gears 11 are all meshed with the teeth of the vertical toothed plate 10. A regulation motor 9 is fixedly connected to the inner wall of the generator 7. The output end of the regulation motor 9 is fixedly connected to the surface of the toothed ring 10. A locking component is also included;

[0088] The locking component includes: an electromagnet 21. The electromagnet 21 is embedded in the inner wall of the induction frame 705. An iron ring 22 is embedded in the inner wall of the power generation coil 704;

[0089] The material of the blade 702 is a waterproof and corrosion-resistant material. The heat storage principle of the heat storage device 12 is pebble heat storage. The heat absorption principle of the heat absorption device 4 is to absorb heat by erecting a plastic film.

[0090] More specifically, in this embodiment: By opening the shaft 3 and making the air outlet face south, in the daily use environment, a temperature difference will be generated between the air outlet and the air inlet of the shaft 3. The temperature difference is used to make the air flow from the high-temperature position to the low-temperature position in the shaft 3. At the same time, by laying a large area of pebbles, a large amount of heat is accumulated at the air inlet of the heat storage device 12, resulting in a greater temperature difference between the foot of the mountain and the top of the mountain, thereby driving the air flow in the shaft 3 to flow rapidly upward. Through the rapidly upward air flow in the shaft 3, the blades 702 on the generator 7 are driven to move by the air flow. Thus, through the transmission of the rotating shaft 703, the power generation coil 704 rotates rapidly along the inner wall of the induction frame 705. Then, using the power generation principle of electromagnetic induction, the magnetic induction lines are continuously cut to carry out power generation work. The generated current is stored through the current receiving component 706. The work of generating current for power generation and storage is a prior art, and the specific principle will not be elaborated here;

[0091] During use, considering that when the temperature difference value between the mountaintop and the bottom of the mountain is less than a certain range, the air flow in the shaft 3 will be relatively slow at this time. The air flow passes through the three groups of generators 7 in sequence, and the flow rate will be further slowed down. Therefore, when the temperature difference between the mountaintop and the bottom of the mountain is small, there is a situation where the air flow is difficult to flow out from the air outlet. At this time, the environmental monitoring component can be used to collect data on the surrounding environment of the device, and the wind direction detection module and the generator adjustment module are used to perform real-time analysis on the collected data, so as to control the deflection state of the blades 702 on the three groups of generators 7 as needed based on the analyzed data, so as to avoid the situation where the air flow in the shaft 3 is difficult to circulate in the form of reducing the air flow resistance;

[0092] When it is necessary to control the deflection of the blade 702, the current stored by the generator 7 generating electricity can be used to make the regulation motor 9 drive slightly, that is, to make the vertical toothed plate 10 rotate slightly. Through the slight rotation of the vertical toothed plate 10, the gear 11 rotates self. Taking the transmission of a single gear 11 as an example, through the self-rotation of the gear 11, the connected rotating shaft 703 can be made to rotate self, and through the self-rotation of the rotating shaft 703, the blade 702 can be made to deflect self, so that the blade 702 is adjusted to a state where it does not block the air flow path. In this way, through the slight rotation of the vertical toothed plate 10, the twenty-five blades 702 on the generator 7 can be adjusted by self-deflection. At the same time, during this process, the current stored by the generator 7 generating electricity can also energize the electromagnet 21, making the electromagnet 21 generate magnetism and attracting the iron ring 22, so that the power generation coil 704 and the induction frame 705 remain relatively stationary, that is, through this measure, the blade 702 will not generate rotational power generation;

[0093] The shaft 3 can be opened by using existing abandoned mine roadways, vertical wells formed by geological exploration, abandoned emergency projects and other existing conditions. It is only necessary to erect a supporting structure on the inner wall, which can greatly reduce the construction cost.

[0094] Embodiment 2, on the basis of the above embodiment:

[0095] Please refer to Figure 2 , in this embodiment: The distance of the shaft 3 can be set to 800 meters, and multiple generators 7 are equidistantly erected at intervals of 100m. Based on this, the vertical space position of the shaft 3 is divided into three sections. When it is necessary to control one of the generators 7 in the above process, in this embodiment, it is regarded as synchronously regulating all the generator sets included in the area involved in the shaft 3. By setting multiple generators 7, the energy conversion rate of the device can be significantly improved.

[0096] Embodiment 3, on the basis of the above embodiment:

[0097] Please refer toFigure 1 , Figures 11 to 14 , the environmental monitoring components include a first temperature sensor and a second temperature sensor. The first temperature sensor and the second temperature sensor are respectively arranged at the air inlet and the air outlet of the shaft 3. A wind direction turning mark is arranged at the air inlet of the ground 1, and a flow velocity sensor and a viscometer are arranged at the air inlet of the shaft 3. A wind pressure sensor is arranged at the air inlet of the shaft 3;

[0098] The process of the wind direction detection module is as follows:

[0099] Taking the radial coincidence direction of the air inlet of the shaft 3 as the 90° direction;

[0100]

[0101] Where WD represents the wind direction influence level;

[0102] θ represents the air inlet angle, that is, the air inlet angle of the shaft 3;

[0103] WC = α×(W 1 -W 2 )

[0104] Where WC represents the temperature difference trigger threshold;

[0105] W 1 is the temperature at the air inlet at the bottom of the mountain;

[0106] W 2 is the temperature at the air outlet at the top of the mountain;

[0107] When WD = 1, it is a high level, indicating that the external wind direction is in a state of superimposing and accelerating the air flow in the shaft 3. At this time, α takes

[0108] When WD = 2, it is a medium level, indicating that the external wind direction is in a state of only accelerating the air flow in the shaft 3. At this time, α takes

[0109] When WD = 3, it is a low level, indicating that the external wind direction is in a state of non-accelerating the air flow in the shaft 3. At this time, α takes 1;

[0110] By detecting the wind direction of the current environment and setting the wind direction influence level, the temperature difference trigger threshold WC is adjusted according to the wind direction influence level. When the actual temperature difference ≥ the temperature difference trigger threshold WC, the regulation component is not started. When the actual temperature difference < the temperature difference trigger threshold WC, the regulation component is started.

[0111] More specifically, in this embodiment: By setting a wind direction turning mark at the air inlet of the ground 1, the wind direction of the current natural environment is detected. By judging the direction of the air inlet angle θ, it is thus judged which of the three states of superposition and acceleration, acceleration or non-acceleration of the air flow generated in the shaft 3 due to the temperature difference, and the temperature difference trigger threshold WC is adjusted according to the current level. That is, when the actual temperature difference ≥ the temperature difference trigger threshold WC, the regulation component is not started. When the actual temperature difference < the temperature difference trigger threshold WC, the regulation component is started. More specifically, when the natural air inlet superimposes and accelerates the air flow in the shaft 3, the temperature difference trigger threshold WC for triggering the operation of the regulation component is relatively low at this time. When the natural air inlet is in a non-accelerated state for the air flow in the shaft 3, the temperature difference trigger threshold WC for triggering the operation of the regulation component is relatively high at this time;

[0112] In this way, first, considering the situation where it is difficult for the air flow to flow out of the air outlet when the temperature difference between the mountaintop and the mountain bottom is small, that is, when the actual temperature difference is less than the temperature difference trigger threshold WC, the blades 702 of the generator 7 can be controlled as needed to avoid the occurrence of difficult flow in the form of reducing the air flow resistance. At the same time, the wind direction factor in the natural environment is also utilized to regulate the temperature difference trigger threshold WC, making the device more practical and the actual regulation timing more accurate.

[0113] Embodiment 4, based on the above embodiment:

[0114] Please refer to Figures 2 to 13 , the environmental data includes the fluid flow velocity v and the fluid Reynolds number value R e , during the adjustment process of the generator adjustment module, the process of obtaining the fluid flow velocity v is as follows:

[0115]

[0116] where v is the fluid flow velocity;

[0117] P air is the air pressure;

[0118] ρ air is the air density;

[0119] Set the wind speed threshold of the fluid flow velocity v to V 1 , when the fluid flow velocity v > the wind speed threshold V 1 , it represents a high wind speed state;

[0120] When the fluid flow velocity v ≤ the wind speed threshold V 1 , it represents a low wind speed state;

[0121] The fluid Reynolds number value R e is obtained as follows:

[0122]

[0123] where R e is the Reynolds number value of the fluid;

[0124] v is the flow velocity of the fluid;

[0125] ρ is the density of the fluid;

[0126] μ is the viscosity coefficient;

[0127] d is the length of the shaft;

[0128] Set the Reynolds threshold value R e of the Reynolds number to R 1 ;

[0129] When R e > R 1 it indicates a high Reynolds number, and at this time, it represents that the air flow is in a turbulent state;

[0130] When R e ≤ R 1 it indicates a low Reynolds number; at this time, it represents that the air flow is in a laminar state;

[0131]

[0132] where A = a, A = b, and A = c respectively represent three fluid states in the shaft (3);

[0133] When A = a, it is the first level, indicating a high fluid flow velocity and a high Reynolds number;

[0134] When A = b, it is the second level, indicating a low fluid flow velocity;

[0135] When A = c, it is the third level, indicating a high fluid flow velocity and a low Reynolds number state;

[0136] When in the first level, the generator 7 at the middle position is turned off. When in the second level, the two generators 7 at the middle position and near the air outlet are turned off. When in the third level, none of the three generators 7 are turned off.

[0137] More specifically, in this embodiment: Through the flow velocity sensor, viscometer, and wind pressure sensor arranged in the shaft 3, the corresponding data is detected. Set the wind speed threshold value of the flow velocity v of the fluid to V 1 , when the flow velocity v of the fluid > the wind speed threshold value V 1 it indicates a high wind speed state. When the flow velocity v of the fluid ≤ the wind speed threshold value V 1 it indicates a low wind speed state, thereby determining whether the air flow in the shaft 3 is in a high speed state or a low speed state, and judging the current Reynolds number value R of the fluid e, based on this, set the fluid Reynolds number value R e The Reynolds threshold of e is R 1 , based on this, determine whether the current air flow is in a turbulent state or a laminar state. When the fluid is a high-velocity turbulent flow, the blades 702 of the generator 7 located in the middle position are deflected and controlled to be in a non-blocking state. When the fluid is a high-velocity laminar flow, all three generators 7 are used normally. When the fluid is at a low velocity, at this time, the blades 702 of the two generators 7 in the middle position and near the air outlet are deflected and controlled to be in a non-blocking state;

[0138] To sum up, when the temperature difference between the mountaintop and the mountain bottom is large, all three generators 6 are used for normal power generation at this time. When the temperature difference between the mountaintop and the mountain bottom is small, by judging the wind speed and Reynolds value of the fluid in the shaft 3, the blades 702 of the three generators 6 are controlled as needed. When the fluid is a high-velocity turbulent flow, the blades 702 of the generator 7 located in the middle position are deflected and controlled to be in a non-blocking state. At this time, the upper and lower two generators 7 are used for power generation. Due to the high wind speed, the air flow in the shaft 3 can circulate, and at the same time, the blades 702 of the middle generator 3 will not block the air flow, so as to increase the distance between adjacent generators 7 in the working state, avoid the further aggravation of the turbulent phenomenon of adjacent two generators 7 in the working state due to the high Reynolds number, and at the same time, it does not affect the continuity of the overall power generation work of the device;

[0139] When the fluid is at a low velocity, the blades 702 of the two generators 7 in the middle position and near the air outlet are deflected and controlled to be in a non-blocking state. At this time, the generator 7 that first contacts the air flow is used for power generation. This measure reduces the resistance of the air flow passing through the shaft 3 and avoids the difficulty of air flow in the shaft 3 by reducing the power generation per unit time of the overall device under the condition of maintaining the overall sustainable power generation. When the fluid is in a high-velocity and low-Reynolds-number state, due to the high wind speed, at this time, there is no need to consider the influence brought by the Reynolds number, that is, all three generators 7 work normally.

[0140] Embodiment 5, based on the above embodiment:

[0141] Please refer to Figures 2 to 14 , the warning process of the warning module is as follows:

[0142]

[0143] where p(t) is the wind pressure at time point t;

[0144] ρ(t) is the air density at time point t, which changes with temperature and air pressure;

[0145] v(t) is the wind speed at time point t;

[0146] Δp = |p(t) - p(t - 1)|

[0147] where p(t) is the wind pressure at time point t;

[0148] p(t - 1) is the wind pressure at time point t - 1;

[0149] Δp is the difference in wind pressure between time point t and time point t - 1;

[0150] Set the wind pressure threshold of the wind pressure difference Δp between time point t and time point t - 1 to be Δp threshold , if the wind pressure threshold Δp threshold < the wind pressure difference Δp between time point t and time point t - 1, it is determined that the wind pressure fluctuation is too large, and the twenty - five blades 702 on the generator 7 may encounter uneven wind pressure, affecting the safe operation. At this time, all three groups of control components operate, so that the blades 702 of all three groups of generators 7 are in a non - working state.

[0151] More specifically, in this embodiment: Considering that too large wind pressure fluctuation will affect the working stability and working efficiency of the blades 702, in order to improve the long - term durability of equipment use, the wind pressure value in the shaft 3 is recorded every other time point, and the wind pressure threshold of the wind pressure difference Δp between time point t and time point t - 1 is set to be Δp threshold， If the wind pressure threshold Δp threshold < the wind pressure difference Δp between time point t and time point t - 1, it is determined that the shaft 3 is in a state of too large wind pressure fluctuation. In this state, the twenty - five blades 702 on the generator 7 may encounter uneven wind pressure. At this time, all three groups of control components operate, so that the blades 702 of all three groups of generators 7 are in a non - working state, thereby avoiding the working environment of abnormal use and preventing the impact on the long - term use stability of the generator 7;

[0152] It should be noted that the priority of the warning module is higher than that of the generator adjustment module.

[0153] Working principle: When the well-type power generation device based on the vertical temperature difference of the mountain body and solar heat collection is in use, the temperature difference factor generated between the air outlet and the air inlet of the shaft 3 is utilized to drive the generator 7 to generate electricity. A heat storage device 12 and a heat absorption device 4 are additionally provided, so that a large amount of heat is accumulated at the air inlet, enabling the device to generate electricity throughout the year. Considering that when the temperature difference value between the mountaintop and the mountain bottom is less than a certain range, the air flow in the shaft 3 will be relatively slow at this time. The air flow passes through the three groups of generators 7 in sequence, and the flow rate will be further reduced. Therefore, when the temperature difference between the mountaintop and the mountain bottom is small, there is a situation where the air flow is difficult to flow out from the air outlet. At this time, the environmental monitoring component can collect data on the surrounding environment of the device, and use the wind direction detection module and the generator adjustment module to analyze the collected data in real time, so as to control the deflection state of the blades 702 on the three groups of generators 7 as needed according to the analyzed data. Before the control, the wind direction of the current environment is first detected and the wind direction influence level is set, and the temperature difference trigger threshold WC is adjusted according to the wind direction influence level. When the natural air inlet superimposes and accelerates the air flow in the shaft 3, the temperature difference trigger threshold WC for triggering the operation of the regulation component is relatively low at this time, while when the natural air inlet is in a non-accelerating state for the air flow in the shaft 3, the temperature difference trigger threshold WC for triggering the operation of the regulation component is relatively high;

[0154] When the actual temperature difference is less than the temperature difference trigger threshold WC, the wind speed and Reynolds value of the fluid in the shaft 3 will also be judged. When the fluid is a high-velocity turbulent flow, the blades 702 of the generator 7 in the middle position are controlled in a deflected manner to make it in a non-blocking state. At this time, the upper and lower two generators 7 are used to generate electricity. Due to the high wind speed, the air flow in the shaft 3 can circulate, and at the same time, the blades 702 of the middle generator 3 will not block the air flow, so as to avoid the further aggravation of the turbulent flow phenomenon between the adjacent operating generators 7 due to the high Reynolds number in the form of increasing the distance between the adjacent operating generators 7, and at the same time, it does not affect the continuity of the overall power generation work of the device;

[0155] When the fluid is at a low flow rate, the blades 702 of the two generators 7 in the middle position and near the air outlet are controlled in a deflected manner to make them in a non-blocking state. At this time, the generator 7 that first comes into contact with the air flow is used to generate electricity. This measure reduces the resistance of the air flow passing through the shaft 3 by reducing the overall power generation per unit time of the device under the condition of maintaining the overall sustainable power generation, and avoids the difficulty of air flow circulation in the shaft 3. When the fluid is in a high-velocity, low-Reynolds-number state, due to the high wind speed, the influence brought by the Reynolds number does not need to be considered at this time, that is, the three generators 7 all operate normally. In this way, in the form of reducing the air flow resistance as needed, the situation where the air flow in the shaft 3 is difficult to circulate can be specifically avoided;

[0156] Meanwhile, when the wind pressure fluctuation in the hoistway 3 is too large, all three groups of regulating components operate, causing the blades 702 of the three groups of generators 7 to be in a non-operating state, thereby avoiding the working environment of abnormal use and preventing it from affecting the long-term use stability of the generator 7.

The scope of the present invention is defined by the appended claims and their equivalents.
