Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation, and more specifically to an energy-saving device for a solar generator. Background Technology

[0002] Solar power generation refers to photovoltaic (PV) power generation. With the development of PV technology, its applications are becoming increasingly widespread, such as residential PV power generation, which uses electricity generated by PV systems to power households, reducing the amount of electricity used from the public grid and achieving energy conservation. However, this method relies on the intensity of sunlight. When the sunlight intensity is weak, such as on cloudy days, during rain or snow, or at night, although the PV panels can still generate electricity, the voltage of the generated electricity is very weak and insufficient to meet household electricity needs. Therefore, this invention proposes a solar generator energy-saving device that can utilize weak wind energy to store strong mechanical energy, and then use this strong mechanical energy to generate high-voltage electricity to power households, thus achieving energy conservation. Summary of the Invention

[0003] To address the problems mentioned in the background above, the present invention provides an energy-saving device for solar generators.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows.

[0005] A solar generator energy-saving device includes an auxiliary energy storage component. The auxiliary energy storage component includes a mounting frame, on which a distribution component, an energy storage component, and a horizontally arranged fan shaft are mounted. The input end of the fan shaft extends to the outside and is provided with blades. The output end of the fan shaft is connected to the input end of the distribution component. The distribution component has multiple output ends, and each output end of the distribution component is connected to an energy storage component. A generator is arranged between the output ends of the multiple energy storage components.

[0006] The energy storage component includes a base, a top seat located above the base, and a connecting rod for connecting the base and the top seat. A main lead screw and a guide rod arranged vertically are installed between the base and the top seat. The main lead screw is connected to the output end of the distribution component through a reducer. A lifting component is provided on the outside of the main lead screw. The lifting component and the guide rod are slidably connected. An energy storage spring is provided between the lifting component and the top seat.

[0007] A vertically arranged auxiliary lead screw is installed between the base and the top seat, and the auxiliary lead screw and the lifting component are connected by a thread.

[0008] As a further improvement and optimization of the present invention, the lifting component includes a support body, a secondary lead screw and the support body are threadedly connected, and the support body and the guide rod are slidably connected.

[0009] The support body is provided with a guide seat, and a slider is slidably mounted on the guide seat along the radial direction of the main lead screw. The side of the slider facing the main lead screw is set as an arc surface and the arc surface is provided with a thread. Multiple sliders are arranged in an array along the circumference of the main lead screw. When the arc surfaces of all sliders are in contact with the main lead screw, the arc surfaces of all sliders cooperate to form a complete threaded hole, and the threaded hole and the main lead screw form a threaded connection.

[0010] As a further improvement and optimization of the present invention, a trigger screw is provided on the support body. The axis of the trigger screw is parallel to the moving direction of the slider and the two are connected by a thread. Multiple trigger screws are provided accordingly.

[0011] A motor is mounted on the top base, and the output end of the motor is connected to a vertically arranged trigger shaft. The trigger shaft and the trigger screw are connected by a power transmission component.

[0012] As a further improvement and optimization of the present invention, the active component of the power transmission component is mounted on the trigger shaft via a connecting component, and when the active component moves together with the lifting component, the trigger shaft continuously outputs power to the active component via the connecting component.

[0013] As a further improvement and optimization of the present invention, the connecting member includes an internal spline disposed on the driving member and an external spline disposed on the trigger shaft.

[0014] As a further improvement and optimization of the present invention, the distribution component includes a first differential, the input half-shaft of the first differential and the sector shaft form a power connection, the ends of the two output half-shafts of the first differential are coaxially provided with connecting shafts, the ends of the two connecting shafts are provided with a second differential, the input half-shaft of the second differential and the connecting shaft form a power connection, the ends of the two output half-shafts of the second differential are coaxially provided with transmission shafts, and there are four corresponding transmission shafts;

[0015] The end of the transmission shaft is connected to the output shaft via a bevel gear set. The output shaft is arranged vertically, and there are four output shafts.

[0016] There are four energy storage components, and the four output shafts are connected to the main screws of the four energy storage components through reducers.

[0017] The mounting bracket is equipped with friction components that switch between a friction state and a release state. When in the friction state, the friction components restrict the rotation of the transmission shaft, and when in the release state, they release the restriction on the rotation of the transmission shaft. There are four friction components corresponding to the transmission shafts.

[0018] As a further improvement and optimization of the present invention, the friction component includes a brake disc disposed on the transmission shaft, a brake pad facing the brake disc, and a linear module for driving the brake pad to move along the axis of the transmission shaft.

[0019] As a further improvement and optimization of the present invention, the input end of the generator is provided with a driven gear, which meshes with a driving gear provided on the mounting bracket. The driving gear and the auxiliary lead screw form a power connection, and four driving gears are provided accordingly.

[0020] As a further improvement and optimization of the present invention, a gear shaft is provided on the mounting bracket. The driving gear and the gear shaft are connected by a ratchet and pawl assembly. The gear shaft is connected to the auxiliary lead screw. When the energy storage component releases mechanical energy to drive the gear shaft to rotate, the gear shaft outputs power to the driving gear in one direction through the ratchet and pawl assembly.

[0021] Compared with the prior art, the beneficial effects of this invention are as follows:

[0022] In this case, a weak external wind blows the blades and fan shaft to rotate. The weak mechanical energy generated by the rotation of the fan shaft is transmitted to the main screw through the distribution component and reducer. Based on the high torque characteristics of the reducer, the main screw is driven to rotate, causing the lifting component to move upward and the energy storage spring to be compressed, thus storing high mechanical energy.

[0023] The threaded connection between the lifting component and the main lead screw is disconnected, and the energy storage spring begins to release its elastic force, which drives the auxiliary lead screw to rotate. The auxiliary lead screw drives the driving gear to rotate through the driven gear, ratchet and pawl components, thereby making the generator run and generating electricity.

[0024] In short, this project can convert weak mechanical energy into stronger mechanical energy, and then use the stronger mechanical energy to generate electricity, obtaining high-voltage electrical energy to supply electricity to households, thus achieving energy-saving effects.

[0025] Furthermore, the mechanical energy accumulation and release of different energy storage components do not interfere with each other. That is, when one energy storage component is accumulating mechanical energy, another energy storage component that has already accumulated enough mechanical energy can simultaneously release mechanical energy to generate electricity. The two do not interfere with each other, resulting in higher efficiency. Attached Figure Description

Detailed Implementation

[0036] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0037] This project utilizes external wind power to generate electricity for households during periods of low light intensity, such as cloudy days, thus achieving energy conservation. It is important to note that one of the core aspects of this project is the use of low external wind power to store high-energy energy, which is then released to generate electricity. The generated voltage is higher, effectively providing electricity for households. This project serves as an auxiliary device for solar power generation systems.

[0038] Reference Figures 1-8 A solar generator energy-saving device includes an auxiliary energy storage component 100. The auxiliary energy storage component 100 includes a mounting frame 101, on which a distribution component 200, an energy storage component 300, and a horizontally arranged fan shaft 102 are mounted.

[0039] The input end of the fan shaft 102 extends to the outside and is provided with blades 103. The blades 103 can be rotated by the external wind, thereby rotating the fan shaft 102 together. The output end of the fan shaft 102 is connected to the input end of the distribution component 200. The distribution component 200 has multiple output ends, and each output end of the distribution component 200 is connected to an energy storage component 300. That is, there are multiple energy storage components 300. Four are shown in the attached drawings of this case. A generator 400 is provided between the output ends of the multiple energy storage components 300.

[0040] In use, no matter how weak the external wind is, it can make the fan shaft 102 rotate, but the rotation speed varies. The distribution component 200 is used to transfer the mechanical energy generated by the rotation of the fan shaft 102 to the energy storage component 300 one by one. Furthermore, only when the mechanical energy stored in a certain energy storage component 300 reaches its maximum will the distribution component 200 transfer the mechanical energy generated by the rotation of the fan shaft 102 to the next energy storage component 300. In this way, energy storage is achieved through the energy storage component 300 and the energy of the stored mechanical energy is relatively high.

[0041] When generating electricity, the energy storage component 300 releases the stored mechanical energy and transfers it to the generator 400 to achieve the purpose of generating electricity. It should be noted that the mechanical energy storage and release of different energy storage components 300 do not interfere with each other. That is, when one energy storage component 300 is storing mechanical energy, another energy storage component 300 that has been fully stored can release mechanical energy at the same time to generate electricity. The two do not interfere with each other and the efficiency is higher.

[0042] Assign component 200:

[0043] Reference Figure 4 The distribution component 200 includes a first differential 201. The input half-shaft of the first differential 201 is connected to the fan shaft 102. The ends of the two output half-shafts of the first differential 201 are coaxially provided with connecting shafts 202. The ends of the two connecting shafts 202 are provided with second differentials 203. Furthermore, the input half-shaft of the second differential 203 is connected to the connecting shafts 202. The ends of the two output half-shafts of the second differential 203 are coaxially provided with transmission shafts 204. That is to say, there are four transmission shafts 204.

[0044] The end of the transmission shaft 204 is poweredly connected to the output shaft 206 via the bevel gear set 205. The output shaft 206 is arranged vertically, and four output shafts 206 are provided. The four output shafts 206 are respectively connected to four energy storage components 300.

[0045] Furthermore, the mounting bracket 101 is also provided with friction elements, which are configured to switch between a friction state and a release state. When in the friction state, they are used to obstruct the rotation of the transmission shaft 204. When in the release state, they remove the obstruction to the transmission shaft 204. There are four friction elements corresponding to the number of transmission shafts 204.

[0046] The friction components include a brake disc 207 mounted on the transmission shaft 204, a brake pad 208 facing the brake disc 207, and a linear module 209 for driving the brake pad 208 to move along the axis of the transmission shaft 204. The linear module 209 can be implemented using existing technologies, such as lead screw linear movement technology, which will not be elaborated here. The linear module 209 drives the brake pad 208 to engage with or disengage from the brake disc 207, thereby causing the friction components to switch states. Based on the principle of the differential, the rotation of the three transmission shafts 204 is hindered, while the last transmission shaft 204 is not hindered. Then, the mechanical energy generated by the rotation of the fan shaft 102 will be completely transferred to the last transmission shaft 204, thereby achieving the controllability of transferring all mechanical energy to a certain energy storage component 300.

[0047] Energy storage module 300:

[0048] Reference Figures 5-7 The energy storage assembly 300 includes a base 301, a top seat 302 located above the base 301, and a connecting rod 303 for connecting the base 301 and the top seat 302.

[0049] A vertically arranged main lead screw 304 and guide rod are installed between the base 301 and the top seat 302. The main lead screw 304 and the output shaft 206 are connected by a reducer 305. A lifting component 306 is provided on the outside of the main lead screw 304. The lifting component 306 is also slidably connected to the guide rod. An energy storage spring 307 is provided between the lifting component 306 and the top seat 302. The energy storage spring 307 has a large elastic coefficient. Due to the presence of the reducer 305, even if the external wind force is weak, the large torque characteristic of the reducer 305 can drive the main lead screw 304 to rotate slowly, thereby causing the lifting component 306 to move upward, compressing the energy storage spring 307, and gradually accumulating a high mechanical energy.

[0050] Furthermore, the lifting component 306 includes a support body 3061, which is slidably connected to the guide rod. A guide seat 3062 is provided on the support body 3061, and a slider 3063 is slidably arranged on the guide seat 3062 along the radial direction of the main lead screw 304. The side of the slider 3063 facing the main lead screw 304 is formed into an arc surface and a thread is provided on the arc surface. Multiple sliders 3063 are arranged in an array along the circumferential direction of the main lead screw 304. When the arc surfaces of all sliders 3063 are in contact with the main lead screw 304, the arc surfaces of all sliders 3063 cooperate to form a complete threaded hole, and the threaded hole and the main lead screw 304 form a threaded connection.

[0051] The support body 3061 is also provided with a trigger screw 3064. The axis of the trigger screw 3064 is parallel to the moving direction of the slider 3063 and the two are connected by a thread. Multiple trigger screws 3064 are provided.

[0052] A motor 308 is mounted on the top seat 302. The output end of the motor 308 is powered by a vertically arranged trigger shaft 309. The trigger shaft 309 and the trigger screw 3064 are powered by a power transmission component 3065. Furthermore, the driving component of the power transmission component 3065 is mounted on the trigger shaft 309 via a connecting component. When the driving component moves together with the lifting component 306, the trigger shaft 309 continuously outputs power to the driving component via the connecting component. Preferably, the connecting component includes an internal spline mounted on the driving component and an external spline mounted on the trigger shaft 309.

[0053] Therefore, the motor 308 can drive the trigger screw 3064 to rotate, thereby causing the threaded hole formed by all the sliders 3063 to form a threaded connection with the main screw 304 or to cancel the threaded connection. The former corresponds to the accumulation of mechanical energy, and the latter corresponds to the release of mechanical energy.

[0054] Furthermore, a vertically arranged auxiliary lead screw 310 is installed between the base 301 and the top seat 302. The auxiliary lead screw 310 is threadedly connected to the support body 3061, and the thread pitch of the auxiliary lead screw 310 is relatively large. Therefore, when the support body 3061 moves down, it can drive the auxiliary lead screw 310 to rotate.

[0055] Reference Figure 8 The input end of the generator 400 is provided with a driven gear 401, which meshes with the driving gear 402 provided on the mounting bracket 101. The driving gear 402 and the auxiliary lead screw 310 form a power connection. There are four driving gears 402.

[0056] Furthermore, a gear shaft is provided on the mounting bracket 101. The driving gear 402 and the gear shaft are connected by a ratchet and pawl assembly 403. The gear shaft is also connected to the lead screw 310. The ratchet and pawl assembly 403 is a technology that can be implemented in the prior art and will not be described in detail. When the energy storage component 300 releases mechanical energy and drives the gear shaft to rotate, the gear shaft outputs power to the driving gear 402 in one direction through the ratchet and pawl assembly 403. Its technical advantage is that, apart from the release of mechanical energy, the driving gear 402 does not output power to the driven gear 401. Moreover, when the driven gear 401 rotates, it only drives the driving gear 402 to idle and does not drive the corresponding gear shaft to rotate. Therefore, the storage of mechanical energy and the release of mechanical energy for power generation do not interfere with each other and can be carried out simultaneously.

[0057] Working principle of the invention:

[0058] A weak external wind blows the blades 103 and the fan shaft 102 to rotate. The weak mechanical energy generated by the rotation of the fan shaft 102 is transmitted to the main screw 304 through the distribution component 200 and the reducer 305. Based on the high torque characteristics of the reducer 305, the main screw 304 is driven to rotate, causing the lifting component 306 to move upward and the energy storage spring 307 to be compressed, thus storing high mechanical energy.

[0059] The threaded connection between the lifting component 306 and the main lead screw 304 is removed, and the energy storage spring 307 begins to release its elastic force, which drives the auxiliary lead screw 310 to rotate. The auxiliary lead screw 310 drives the drive gear 402 to rotate through the driven gear 401 and the ratchet and pawl component 403, thereby causing the generator 400 to run and generate electricity.

[0060] Its technological advantages lie in:

[0061] This invention can convert weak mechanical energy into stronger mechanical energy, and then use the stronger mechanical energy to generate electricity, obtaining high-voltage electrical energy to supply electricity to households, thus achieving energy-saving effects.
