Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation and energy storage technology, and in particular to a photovoltaic power generation and energy storage device. Background Technology

[0002] Photovoltaic power generation, as a clean and renewable energy source, plays a crucial role in energy structure transformation. Integrated photovoltaic power generation and energy storage devices, capable of collecting, converting, storing, and outputting solar energy on demand, are widely used in various scenarios such as outdoor operations, distributed power supply for residential use, and mobile power supply, becoming an important carrier for the practical application of photovoltaic power generation technology. However, existing photovoltaic power generation and energy storage devices have gradually revealed many technical problems that urgently need to be solved in practical applications, seriously affecting the power generation efficiency, equipment lifespan, and ease of use. Specific problems are as follows: The solar panels of existing photovoltaic power generation and energy storage devices are mostly fixed and exposed. When there is no demand for power generation, the panels are directly exposed to the outdoor environment, which makes them susceptible to erosion from sand, rain, snow, and hail, as well as impacts and scratches from external objects. This causes wear and cracking of the sun-receiving surface of the panels, significantly shortening the lifespan of the solar panels. The photovoltaic panels and energy storage boxes in existing photovoltaic power generation and energy storage devices are designed separately, with each being an independent structure without an integrated layout. This not only requires separate planning of placement space when storing the devices, resulting in a large overall space occupation and low space utilization, but also severely limits application scenarios in small spaces. Furthermore, the separate structure also necessitates separate operations during device handling and transportation, which is cumbersome and increases transportation costs. During installation, additional planning of the placement and spacing of the two components is required, further increasing the complexity of the installation process. Summary of the Invention

[0003] This invention relates to a photovoltaic power generation and energy storage device, which solves the problems of existing photovoltaic power generation and energy storage devices, where the solar panels are mostly fixed and exposed, making them susceptible to outdoor environmental corrosion and external impact damage, thus shortening their service life. In addition, the photovoltaic panels and energy storage boxes are designed separately, which results in large space occupation, low space utilization, cumbersome handling and transportation, and complicated installation.

[0006] Furthermore, the bottom surface of the inner end of the storage slot is symmetrically provided with two sliding rail grooves a; the bottom surface of the storage plate is symmetrically provided with two sets of sliding rail wheels, which are slidably inserted into the two sliding rail grooves a respectively.

[0007] Furthermore, a right-side support block is provided on the front right side of the external block, and the rear side of the left end face of the right-side support block is connected to the front end face of the external block by a hinge; an iron block a is fixedly installed on the left end face of the right-side support block; a right-side limiting plate is fixedly installed on the rear side of the right end face of the right-side support block, and a right-side limiting hole is provided on the right-side limiting plate; a slide rail groove b is provided on the top surface of the right-side support block.

[0008] Furthermore, a left support block is provided on the front left side of the external block, and the rear side of the right end face of the left support block is connected to the front end face of the external block by a hinge; an iron block b is fixedly installed on the right end face of the left support block; a left limiting plate is fixedly installed on the rear side of the left end face of the left support block, and a left limiting hole is provided on the left limiting plate; a slide rail groove c is provided on the top surface of the left support block.

[0009] Furthermore, the front end face of the external block is symmetrically arranged and has two magnet blocks embedded within it; when the left end face of the right support block is parallel to the front end face of the external block, the iron block a is magnetically attracted to the magnet block located on the right side; when the right end face of the left support block is parallel to the front end face of the external block, the iron block b is magnetically attracted to the magnet block located on the left side.

[0010] Furthermore, the front end face of the external block is symmetrically provided with two limiting threaded holes, and limiting bolts are installed in the internal threads of the limiting threaded holes; when the right limiting hole and the limiting threaded hole on the right side are coaxial, the slide rail groove b corresponds to the slide rail groove a on the right side; when the left limiting hole and the limiting threaded hole on the left side are coaxial, the slide rail groove c corresponds to the slide rail groove a on the left side.

[0011] Furthermore, a locking mounting plate is fixedly installed on both the upper and lower sides of the left and right end faces of the external block, and the locking mounting plate has locking mounting holes; the external block, locking mounting plate, locking mounting holes, storage groove, slide rail groove a, wiping cotton strip, limit bolt, telescopic auxiliary groove, limit threaded hole, electric push rod, magnet block, right side support block, right side limit plate, right side limit hole, slide rail groove b, iron block a, left side support block, left side limit plate, left side limit hole, slide rail groove c, iron block b, storage plate, telescopic auxiliary plate, slide rail wheel, and solar panel together form a photovoltaic power generation auxiliary mechanism.

[0012] This invention provides a photovoltaic power generation and energy storage device, which has the following beneficial effects: This invention features a storage slot and a retractable storage plate structure. In the non-power generation state, the solar panel can be completely stored in the storage slot, preventing wear and damage to the sun-receiving surface of the panel caused by external dust, wind, rain, and impacts. At the same time, the left and right support blocks can be magnetically attached for folding and storage, attaching to the front of the external block without occupying extra space. The overall structure forms a closed-loop protection in the standby state, significantly extending the service life of the solar panel and various transmission components. The switching steps between the storage standby state and the unfolded power generation state of the device are simple. The extension and retraction of the solar panel can be achieved by an electric push rod. Fixing and storing the support blocks only requires tightening / unscrewing the limit bolts and magnetic attachment operations. The operating conditions can be quickly switched according to the lighting conditions (such as day / night, sunny / rainy), flexibly adapting to different photovoltaic power generation needs.

[0013] When the invention is deployed for power generation, the left and right support blocks are rigidly fixed with bolts, and their slide rail grooves are precisely aligned with the slide rail grooves inside the storage groove. The support blocks also provide stable bottom support for the extended storage plate, preventing the storage plate from sagging or shifting due to its own weight. This ensures that the solar panel is always in a horizontal, unobstructed, and effective light-receiving position, improving photoelectric conversion efficiency. On the other hand, the wiping cotton strips installed inside the storage groove are always in contact with the top surface of the solar panel. During the extension and retraction of the storage plate, they can automatically wipe away dust, floating dust, and other impurities on the surface of the panel, eliminating the need for manual cleaning and ensuring the cleanliness of the light-receiving surface. This fundamentally avoids the problem of reduced power generation efficiency caused by dirt obstruction.

[0014] In this invention, the slide rail wheel at the bottom of the storage plate forms a sliding insertion engagement with the slide rail groove. When the electric push rod drives the storage plate to extend or retract, the slide rail structure can effectively limit the sliding trajectory of the storage plate, ensuring the smoothness of its expansion and contraction process and avoiding jamming or deviation. At the same time, the left and right support blocks are rigidly connected to the external block through limiting bolts, providing reliable support for the extended storage plate, effectively distributing the weight of the storage plate and the solar panel, reducing the stress loss of the transmission components, reducing the failure rate during equipment operation, and ensuring the continuity of photovoltaic power generation.

[0015] This invention features a compact, integrated layout of the photovoltaic panel and the photovoltaic energy storage box, eliminating the need for separate planning and installation space for the photovoltaic panel. The overall size and footprint of the device are significantly reduced compared to a separate structure, resulting in a substantial improvement in space utilization. The integrated structure makes the device a single unit, eliminating the need for separate handling and securing of the photovoltaic panel and the photovoltaic energy storage box during transport. The entire device can be transported in a single operation, reducing the number of transport steps and manpower required. It also avoids the risk of individual collisions and damage to the photovoltaic panel and the photovoltaic energy storage box during transport, which is common with separate structures, thus reducing the cost and losses associated with equipment transport.

[0020] Example: Please refer to Figures 1 to 11 : This invention proposes a photovoltaic power generation and energy storage device, comprising: a photovoltaic energy storage box 1, an external block 2 on the top surface of the photovoltaic energy storage box 1, a storage groove 203 on the front surface of the external block 2, a telescopic auxiliary groove 207 in the middle of the bottom surface of the inner end of the storage groove 203, and an electric push rod 209 fixedly installed on the rear side of the inner end of the telescopic auxiliary groove 207; a storage plate 5 is slidably installed inside the storage groove 203, and a solar panel 503 electrically connected to the photovoltaic energy storage box 1 is embedded in the top surface of the storage plate 5. The solar panel 503 is connected to the energy storage unit and inverter control inside the photovoltaic energy storage box 1 through electrical circuits. The modules are electrically connected, which can efficiently convert solar radiation energy into electrical energy. The generated electrical energy is directly transmitted to the photovoltaic energy storage box 1 for storage, allocation and output, realizing the coordinated operation of photovoltaic power generation and electrical energy storage. A telescopic auxiliary plate 501 is fixedly installed in the middle of the front side of the bottom end of the storage plate 5. The push rod end of the electric push rod 209 is fixedly connected to the rear end face of the telescopic auxiliary plate 501. When the electric push rod 209 is in the retracted state, the front end face of the storage plate 5 and the front end face of the external block 2 are on the same vertical plane. When the electric push rod 209 is in the extended state, the solar panel 503 is located outside the storage groove 203.

[0021] A wiping cotton strip 205 is fixedly installed on the front side of the top end of the inner end of the storage slot 203. The bottom end of the wiping cotton strip 205 is on the same horizontal plane as the top end of the storage plate 5 and the top end of the solar panel 503.

[0022] The storage slot 203 has two sliding rail slots a204 that are symmetrically arranged on the bottom surface of its inner end; the storage plate 5 has two sets of sliding rail wheels 502 that are symmetrically arranged on the bottom surface of its inner end, and the two sets of sliding rail wheels 502 are slidably inserted into the two sliding rail slots a204 respectively.

[0023] The outer block 2 has a right support block 3 on the front right side.

[0024] The outer block 2 has a left support block 4 on the front left side. The rear side of the right end face of the left support block 4 is connected to the front end face of the outer block 2 by a hinge. An iron block b404 is fixedly installed on the right end face of the left support block 4. A left limiting plate 401 is fixedly installed on the rear side of the left end face of the left support block 4. A left limiting hole 402 is opened on the left limiting plate 401. A slide rail groove c403 is opened on the top surface of the left support block 4.

[0025] The outer block 2 has two magnet blocks 2010 embedded in its front end face in a symmetrical manner. When the left end face of the right support block 3 is parallel to the front end face of the outer block 2, the iron block a304 is magnetically attracted to the magnet block 2010 on the right side. When the right end face of the left support block 4 is parallel to the front end face of the outer block 2, the iron block b404 is magnetically attracted to the magnet block 2010 on the left side.

[0026] The front end face of the external block 2 is symmetrically provided with two limiting threaded holes 208, and limiting bolts 206 are installed in the internal threads of the limiting threaded holes 208. When the right limiting hole 302 and the right limiting threaded hole 208 are coaxial, the slide rail groove b303 corresponds to the slide rail groove a204 on the right. When the left limiting hole 402 and the left limiting threaded hole 208 are coaxial, the slide rail groove c403 corresponds to the slide rail groove a204 on the left.

[0027] Among them, a locking mounting plate 201 is fixedly installed on the upper and lower sides of the left and right end faces of the external block 2, and the locking mounting plate 201 has a locking mounting hole 202. The external block 2, the locking mounting plate 201, the locking mounting hole 202, the storage groove 203, the slide rail groove a204, the wiping cotton strip 205, the limiting bolt 206, the telescopic auxiliary groove 207, the limiting threaded hole 208, the electric push rod 209, the magnet block 2010, the right support block 3, the right limiting plate 301, the right limiting hole 302, the slide rail groove b303, the iron block a304, the left support block 4, the left limiting plate 401, the left limiting hole 402, the slide rail groove c403, the iron block b404, the storage plate 5, the telescopic auxiliary plate 501, the slide rail wheel 502, and the solar panel 503 together form a photovoltaic power generation auxiliary mechanism.

[0028] The working principle of this embodiment: Storage standby state: The device is fixed in place by locking the mounting holes 202 on the mounting plates 201 on both sides of the outer block 2. At this time, the electric push rod 209 is in the retracted state, which drives the storage plate 5 to be completely stored in the storage groove 203 of the outer block 2. The front surface of the storage plate 5 is kept at the same vertical plane as the front surface of the outer block 2. The solar panel 503 is enclosed in the storage groove 203 to prevent damage caused by wind, rain, dust, collision, etc. At the same time, the left support block 4 and the right support block 3 are magnetically attached to the magnet block 2010 at the front of the outer block 2 through their respective iron blocks b404 and a304, and are attached to the front of the outer block 2 in a folded state without occupying extra space. To prepare for and operate the power generation system: First, release the magnetic fixation of the left support block 4 and the right support block 3. Rotate the left support block 4 and the right support block 3 outwards respectively, so that the left limiting hole 402 of the left limiting plate 401 on the left support block 4 and the right limiting hole 302 of the right limiting plate 301 on the right support block 3 are coaxial with the limiting threaded hole 208 at the corresponding position on the external block 2. Pass the limiting bolt 206 through the corresponding limiting hole and screw it into the limiting threaded hole 208 to complete the rigid fixation of the left support block 4 and the right support block 3. At this time, the slide rail groove c403 at the top of the left support block 4 and the slide rail groove b303 at the top of the right support block 3 are precisely aligned with the slide rail groove a204 in the storage groove 203 to form a continuous and horizontal sliding track. When the electric push rod 209 is powered on, it extends and pushes the telescopic auxiliary plate 501 at the bottom of the storage plate 5, causing the storage plate 5 to slide forward along the aligned slide rail groove. The two sets of slide rail wheels 502 at the bottom of the storage plate 5 slide and engage with the slide rail groove to ensure the smoothness of the sliding process of the storage plate 5 until the solar panel 503 is completely extended outside the storage groove 203 and is in an unobstructed horizontal position receiving sunlight. The solar panel 503 receives solar energy and converts it into electrical energy. Through electrical connection with the photovoltaic energy storage box 1, the converted electrical energy is transmitted to the photovoltaic energy storage box 1, where the photovoltaic energy storage box 1 stores the electrical energy and allocates it as needed. At the same time, the fixed left support block 4 and right support block 3 provide bottom support for the extended storage plate 5, preventing the storage plate 5 from sagging or shifting due to its own weight and that of the solar panel 503. This ensures that the solar panel 503 is always in a horizontal and effective light-receiving state, improving the photoelectric conversion efficiency and power generation stability. During the entire sliding process of the electric push rod 209 driving the storage plate 5 to extend forward and retract backward, the bottom surface of the wiping cotton strip 205 in the storage groove 203 remains at the same horizontal plane and in continuous contact with the solar panel 503 and the top surface of the storage plate 5. With the relative sliding between the storage plate 5 and the wiping cotton strip 205, the wiping cotton strip 205 can automatically wipe away the dust, floating dust and other impurities attached to the surface of the solar panel 503, ensuring that the light-receiving surface of the solar panel 503 is clean, avoiding the obstruction of dirt and affecting the photoelectric conversion efficiency, realizing the automatic self-cleaning of the solar panel 503, without the need for manual additional wiping and maintenance; When power generation is not required (such as at night or in rainy weather), the electric push rod 209 is energized and retracts. Its push rod end pulls the telescopic auxiliary plate 501, causing the storage plate 5 to slide along the slide rail grooves a204, b303, and c403 into the storage groove 203. The solar panel 503 is gradually retracted into the storage groove 203 along with the storage plate 5. After the storage plate 5 is completely reset, the limit bolt 206 is unscrewed to release the rigid fixation of the left support block 4 and the right support block 3. The two support blocks are rotated towards the outward block 2, so that the iron blocks a304 and b404 are magnetically attracted and attached to the corresponding magnetic blocks 2010, completing the folding and storage of the left support block 4 and the right support block 3. The device returns to the low-power storage standby state, continuously protecting the solar panel 503.
