Description

Technical Field

[0001] The present invention belongs to the field of photovoltaics, and specifically relates to an energy storage device for a photovoltaic power station. Background Art

[0002] A photovoltaic power station refers to a photovoltaic power generation system connected to the power grid and transmitting electricity to the power grid, which can be divided into grid-connected power generation systems with and without storage batteries. Photovoltaic power generation is one of the important means of converting light energy into electrical energy.

[0003] Energy storage in a photovoltaic power station generally uses dedicated battery modules to store the light energy collected by the photovoltaic panels in the battery modules for subsequent discharging and reuse processes. Such battery modules need to meet characteristics such as large capacity, long service life, and good heat dissipation.

[0004] A photovoltaic power station needs to transfer the generated electrical energy to an energy storage device for power storage. Generally, a large number of photovoltaic panels are installed in a photovoltaic power station, resulting in a large number and complexity of the power transmission lines connecting the photovoltaic panels and the energy storage device. During circuit maintenance or inspection, the crowded lines are not only unfavorable for troubleshooting but also waste a lot of time for maintenance personnel.

[0005] Therefore, the present invention provides an energy storage device for a photovoltaic power station. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art and solve at least one of the technical problems proposed in the background art.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: An energy storage device for a photovoltaic power station according to the present invention includes a protective shell. Inside the protective shell, a number of storage batteries are provided. Connecting lines are distributed on the inner wall of the protective shell. An output socket and an input socket are fixedly installed on the outer side of the protective shell. Both the output socket and the input socket are connected to the storage batteries through the connecting lines. On the side of the input socket away from the protective shell, a protective frame is fixedly installed. Inside the protective frame, two sliding rods are fixedly installed. The two sliding rods are symmetrically arranged and are vertically arranged. Five guide rails are slidably connected between the two sliding rods. Six transmission seats are slidably connected in the middle of the guide rails. The transmission seats are electrically connected to the storage batteries. Through the setting of the input socket, the lines of the photovoltaic panels are docked with a number of transmission seats. When circuit maintenance or troubleshooting is required, only six transmission seats in the same row need to be slid to one side to unfold, and then the five guide rails are slid vertically along the sliding rods to unfold, so that the originally gathered lines can be fully unfolded, separating the power transmission lines, effectively facilitating the circuit troubleshooting and maintenance process. And after the troubleshooting is completed, a number of transmission seats can be slid back to the corner of the input socket to gather the lines, reducing the occupied space of the device and improving the practicality of the device.

[0008] Preferably, a first rotating shaft is rotatably connected to the top surface of the transmission base. The first rotating shaft is located on the side of the transmission base close to the protective shell. An unfolding frame is arranged between adjacent transmission bases. The number of unfolding frames is five. The unfolding frame includes two long rods. A second rotating shaft is rotatably connected between the two long rods. One end of the long rod away from the second rotating shaft is rotatably connected to the outer side of the first rotating shaft. A shielding curtain is arranged on the outer side of the protective frame. During operation, in cooperation with the arrangement of the unfolding frame, when the transverse transmission base is unfolded, only the outermost transmission base needs to be pulled. As the outermost transmission base moves, the five unfolding frames will rotate and unfold in sequence. When the five unfolding frames are fully opened and parallel, the five transmission bases can be arranged equidistantly on the guide rail. Through this setting, the unfolding process of the circuit becomes convenient, and at the same time, the final unfolding distribution is also the most reasonable, further facilitating the troubleshooting and maintenance of the circuit. At the same time, under this setting, thirty transmission bases are predetermined at the beginning. Some can be used first, and some can be left unused. As the photovoltaic panels are built and increased, the circuit can be supplemented to the unused transmission bases, facilitating the subsequent circuit connection process.

[0009] Preferably, five groups of sliding grooves are opened on the side of the input socket away from the protective shell. The five groups of sliding grooves are arranged in parallel and are horizontally arranged. A top plate is slidably connected to the inner side of the sliding groove. A power component is arranged on the outer side of the top plate. The power component is used to drive the top plate to move. During operation, when the transmission base needs to be unfolded, only the power component needs to be started to push the top plate outwards, and the unfolding frame can be pushed out of the sliding groove, so that the transmission base can be unfolded in the horizontal direction without manual operation. And the setting that part of the unfolding frame is located in the sliding groove makes the guide rail unable to move up and down before the unfolding frame is unfolded. Through this setting, the unfolding of the transmission base becomes orderly and neat, reducing the problem of wire entanglement during the unfolding process.

[0010] Preferably, the guide rail includes an upper rail and a lower rail. The two ends of the upper rail and the lower rail are fixedly connected to each other. An inner groove is opened on the top surface of the upper rail. Two electric wheels are slidably connected to the inner side of the inner groove. One end of the electric wheel is rotatably connected to a folding plate. A third rotating shaft is rotatably connected between the two folding plates. During operation, when a row of transmission bases is unfolded, the two electric wheels are started to rotate, so that the two electric wheels move towards the center, causing the two folding plates to be lifted upwards from the third rotating shaft at the center. Through this setting, adjacent guide rails can be separated from each other. In cooperation with the setting of the power component, the unfolding process of the transmission base becomes fully mechanized without manual operation.

[0011] Preferably, thirty connecting seats are fixedly installed at one end of the input socket close to the transmission seat. The connecting seats are connected to the storage battery. The thirty connecting seats are arranged in a matrix and are all located at the corners of the input socket. A connecting seat is fixedly installed on one side of the transmission seat close to the input socket. The connecting seat is communicated with the transmission seat through the connecting seat. The connecting seat is made of metal material. An electric telescopic rod is fixedly connected between the connecting seat and the input socket. During operation, when the transmission seat needs to be unfolded for circuit maintenance, first start the electric telescopic rod to retract the connecting seat, so that the transmission seat is powered off from the storage battery. When the maintenance is completed and all the connecting seats return to the corners, then start the electric telescopic rod to push the connecting seat outwards, so that the connecting seat is inserted into the connecting seat, and the transmission seat is powered on, making the circuit completely disconnected during the maintenance process. At the same time, the physical docking can fix the connecting seats piled up in the corner and reduce the effect of the transmission seat constantly swinging under the pulling of the wire.

[0012] Preferably, two card slots are opened on both the top surface and the bottom surface of the transmission seat. The upper rail and the lower rail are both slidably connected to the transmission seat through the card slots. Three sliding balls are rotatably connected to both the top surface and the bottom surface of the transmission seat. The sliding balls are located between the two card slots. During operation, through the setting of the card slots, the upper rail and the lower rail can stably hold the transmission seat, making the sliding of the transmission seat stable. The setting of the sliding balls can reduce the friction force brought by the sliding of the transmission seat and make the movement of the transmission seat smoother.

[0013] Preferably, the power assembly includes two driving wheels. The driving wheels are arranged on both sides of the top plate. The outer sides of the driving wheels are movably fitted with the inner walls of the sliding grooves. During operation, when the unfolding frame needs to be pushed outwards, start the driving wheels to drive the top plate to move, so that the unfolding frame can be smoothly pushed out of the sliding groove, and the six transmission seats are horizontally unfolded. And as the guide rail moves upwards, there is no space for the unfolding frame to retract, so that the unfolding frame is always in the unfolded state.

[0014] Preferably, the side of the second rotating shaft away from the transmission seat is semicircularly arranged. The outer side of the second rotating shaft is smooth. The top plate is made of magnetic material, and the second rotating shaft is made of metal material. During operation, in cooperation with the arc setting on the outer side of the second rotating shaft, the friction force between the second rotating shaft and the outer side of the top plate can be reduced. At the same time, when the guide rail drives the unfolding frame to rise, the smooth setting on the outer side of the second rotating shaft can also make the second rotating shaft slide more easily. The setting of the magnetic material and the metal material enables, when finally returning, only to start the driving wheels to drive the top plate to move inwards, and under the adsorption effect, the unfolding frame can be pulled into the bent state. Through this setting, a fully mechanized unfolding and returning process of the transmission seat is realized.

[0015] Preferably, the length of the top plate is less than the inner length of the chute. Both ends of the top plate are bent, and the bending direction is towards the side away from the unfolding frame. The driving wheel is connected to the outermost end of the top plate. During operation, in cooperation with the structure of the top plate, after the driving wheel pushes the top plate out to be flush with the chute outlet, the driving wheel still remains inside the chute, ensuring the effect of subsequent transmission.

[0016] Preferably, limiting rods are fixedly installed at both the upper and lower ends of the top plate. Limiting grooves are formed on the inner wall of the chute, and the limiting rods are slidably connected to the limiting grooves. During operation, the setting of the limiting rods can limit the top plate in the chute, reducing the problem that the driving wheel drives the top plate to protrude outwards too much, resulting in hindrance to the movement of the unfolding frame.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. For the photovoltaic power station energy storage device of the present invention, through the settings of the input socket and the transmission seat, the circuit of the photovoltaic panel is docked with several transmission seats. When it is necessary to repair or check the circuit, only need to slide six transmission seats in the same row to one side to unfold, and then slide five guide rails along the sliding rod in the vertical direction to unfold, then the originally gathered circuits can be fully unfolded, separating the power transmission lines, effectively facilitating the circuit inspection and repair process. And after the inspection is completed, several transmission seats can be slid to the corner of the input socket again, making the circuits gather together, reducing the occupied space of the device, and improving the practicability of the device.

[0019] 2. For the photovoltaic power station energy storage device of the present invention, in cooperation with the setting of the unfolding frame, when unfolding the horizontal transmission seat, only need to pull the outermost transmission seat. As the outermost transmission seat moves, five unfolding frames will rotate and unfold in sequence. When the five unfolding frames are fully opened to be parallel, the five transmission seats can be arranged equidistantly on the guide rail. Through this setting, the unfolding process of the circuits becomes convenient, and at the same time, the final unfolding distribution is also the most reasonable, further facilitating the circuit inspection and repair. At the same time, under this setting, thirty transmission seats are pre-determined at the beginning. Some can be used first, and some can be left unused. As the construction and increase of the photovoltaic panels, the circuits can be supplemented to the unused transmission seats, facilitating the subsequent circuit connection process.

Specific Embodiments

[0028] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0029] Embodiment 1

[0030] As Figures 1 to 3As shown in the figure, a photovoltaic power station energy storage device according to an embodiment of the present invention includes a protective case 1. Inside the protective case 1, a plurality of storage batteries 6 are provided. Connecting lines are distributed on the inner wall of the protective case 1. An output socket 2 and an input socket 3 are fixedly installed on the outside of the protective case 1. Both the output socket 2 and the input socket 3 are connected to the storage battery 6 through the connecting lines. On the side of the input socket 3 away from the protective case 1, a protective frame 7 is fixedly installed. Inside the protective frame 7, two sliding rods 10 are fixedly installed. The two sliding rods 10 are symmetrically arranged and are vertically arranged. Five guide rails 9 are slidably connected between the two sliding rods 10. Six transmission seats 4 are slidably connected to the middle of the guide rail 9. The transmission seats 4 are electrically connected to the storage battery 6. During operation, the photovoltaic power station needs to transfer the generated electric energy to the energy storage device for power storage. Generally, a large number of photovoltaic panels are set in the photovoltaic power station, so that there are many and miscellaneous power transmission lines connecting the photovoltaic panels and the energy storage device. During circuit maintenance or inspection, the crowded lines are not only not conducive to troubleshooting, but also waste a lot of time of the maintenance personnel. Through the setting of the input socket 3, the lines of the photovoltaic panels are docked with a plurality of transmission seats 4. When circuit maintenance or troubleshooting is required, only six transmission seats 4 in the same row need to be slid and unfolded to one side, and then the five guide rails 9 are slid and unfolded vertically along the sliding rods 10, so that the originally gathered lines can be fully unfolded, separating the power transmission lines, effectively facilitating the line troubleshooting and maintenance process. And after the troubleshooting is completed, a plurality of transmission seats 4 can be slid to the corner of the input socket 3 again, so that the lines are gathered, reducing the occupied space of the device and improving the practicability of the device.

[0031] As Figures 1 to 3 As shown in the figure, a rotating shaft 11 is rotatably connected to the top surface of the transmission seat 4. The rotating shaft 11 is located on the side of the transmission seat 4 close to the protective case 1. An unfolding frame 12 is provided between adjacent transmission seats 4. The number of the unfolding frames 12 is five. The unfolding frame 12 includes two long rods. A rotating shaft 13 is rotatably connected between the two long rods. The end of the long rod away from the rotating shaft 13 is rotatably connected to the outside of the rotating shaft 11. A shielding curtain 5 is provided on the outside of the protective frame 7. During operation, in cooperation with the setting of the unfolding frame 12, when unfolding the horizontal transmission seats 4, only the outermost transmission seat 4 needs to be pulled. As the outermost transmission seat 4 moves, the five unfolding frames 12 will rotate and unfold in sequence. When the five unfolding frames 12 are fully opened to be parallel, the five transmission seats 4 can be arranged at equal distances on the guide rail 9. Through this setting, the process of unfolding the lines becomes convenient, and at the same time, the final unfolding distribution is also the most reasonable, further facilitating the line troubleshooting and maintenance. At the same time, under this setting, thirty transmission seats 4 are pre-determined at the beginning. Some can be used first, and some can be left unused. As the construction and increase of the photovoltaic panels, the lines can be supplemented to the unused transmission seats 4, facilitating the subsequent line connection process.

[0032] As shown Figures 2 to 4 in the figure, five groups of sliding grooves 8 are provided on the side of the input socket 3 away from the protective shell 1. The five groups of sliding grooves 8 are arranged in parallel and are horizontally arranged. A top plate 14 is slidably connected to the inner side of the sliding groove 8. A power assembly is arranged on the outer side of the top plate 14. The power assembly is used to drive the top plate 14 to move. During work, when the transmission seat 4 needs to be unfolded, only need to start the power assembly to push the top plate 14 outwards, then the unfolding frame 12 can be pushed out of the sliding groove 8, so that the transmission seat 4 can be unfolded in the horizontal direction without manual operation. And the setting that part of the unfolding frame 12 is located in the sliding groove 8 makes the guide rail 9 unable to move up and down before the unfolding frame 12 is unfolded. Through this setting, the unfolding of the transmission seat 4 becomes orderly and neat, reducing the problem of wire entanglement during the unfolding process.

[0033] As shown Figures 2 to 5 in the figure, the guide rail 9 includes an upper rail 17 and a lower rail 18. The two ends of the upper rail 17 and the lower rail 18 are fixedly connected to each other. An inner groove is provided on the top surface of the upper rail 17. Two electric wheels 19 are slidably connected to the inner side of the inner groove. One end of the electric wheel 19 is rotatably connected to a folding plate 20. A rotating shaft three 21 is rotatably connected between the two folding plates 20. During work, when a row of transmission seats 4 are unfolded, start the two electric wheels 19 to rotate, and make the two electric wheels 19 approach the center, so that the two folding plates 20 are lifted upwards from the rotating shaft three 21 at the center. Through this setting, adjacent guide rails 9 can be separated from each other. Cooperating with the setting of the power assembly, the unfolding process of the transmission seat 4 becomes fully mechanized without manual operation.

[0034] As shown Figures 2 to 4 in the figure, thirty connecting seats 16 are fixedly installed at one end of the input socket 3 close to the transmission seat 4. The connecting seats 16 are connected to the storage battery 6. The thirty connecting seats 16 are arranged in a matrix and are all located at the corners of the input socket 3. A connecting seat 22 is fixedly installed on the side of the transmission seat 4 close to the input socket 3. The connecting seat 22 is communicated with the transmission seat 4 through the connecting seat 16. The connecting seat 16 is made of metal material. An electric telescopic rod 25 is fixedly connected between the connecting seat 16 and the input socket 3. During work, when the transmission seat 4 needs to be unfolded for circuit maintenance, first start the electric telescopic rod 25 to retract the connecting seat 16, so that the transmission seat 4 is powered off from the storage battery 6. When the maintenance is completed and all the connecting seats 16 return to the corners, then start the electric telescopic rod 25 to push the connecting seat 16 outwards, so that the connecting seat 16 is inserted into the connecting seat 22, and the transmission seat 4 is powered on, making the circuit break completely during the maintenance process. At the same time, the physical connection can fix the connecting seats 16 piled up in the corners, reducing the effect of the transmission seat 4 swinging continuously under the pulling of the wire.

[0035] As shown Figures 3 to 5As shown, two card slots 23 are provided on both the top surface and the bottom surface of the transfer seat 4. The upper rail 17 and the lower rail 18 are both slidably connected to the transfer seat 4 through the card slots 23. Three sliding balls 24 are rotatably connected to both the top surface and the bottom surface of the transfer seat 4. The sliding balls 24 are located between the two card slots 23. During operation, through the setting of the card slots 23, the upper rail 17 and the lower rail 18 stably clamp the transfer seat 4, making the sliding of the transfer seat 4 stable. The setting of the sliding balls 24 can reduce the friction generated when the transfer seat 4 slides, making the movement of the transfer seat 4 smoother.

[0036] As Figure 2 shown, the power assembly includes two drive wheels 15. The drive wheels 15 are arranged on both sides of the top plate 14. The outer sides of the drive wheels 15 are movably fitted with the inner walls of the sliding grooves 8. During operation, when the deployment frame 12 needs to be pushed outwards, the drive wheels 15 are started to drive the top plate 14 to move, so that the deployment frame 12 can be smoothly pushed out of the sliding groove 8, and the six transfer seats 4 are horizontally deployed. And as the guide rail 9 moves upwards, there is no space for the deployment frame 12 to retract, so that the deployment frame 12 is always in the deployed state.

[0037] As Figures 3 to 4 shown, the side of the second rotating shaft 13 away from the transfer seat 4 is arranged in a semi-circular arc shape. The outer side of the second rotating shaft 13 is smooth. The top plate 14 is made of a magnetic material, and the second rotating shaft 13 is made of a metal material. During operation, in cooperation with the arc setting on the outer side of the second rotating shaft 13, the friction between the second rotating shaft 13 and the outer side of the top plate 14 can be reduced. At the same time, when the guide rail 9 drives the deployment frame 12 to rise, the smooth setting on the outer side of the second rotating shaft 13 can also make the second rotating shaft 13 slide more easily. The setting of the magnetic material and the metal material enables, when finally returning, only by starting the drive wheels 15 to drive the top plate 14 to move inwards, and under the adsorption effect, the deployment frame 12 can be pulled into the bent state. Through this setting, the fully mechanized deployment and return process of the transfer seat 4 is realized.

[0038] Embodiment 2

[0039] As Figure 6 shown, the length of the top plate 14 is less than the inner length of the sliding groove 8. Both ends of the top plate 14 are bent. The bending direction of the top plate 14 is towards the side away from the deployment frame 12. The drive wheels 15 are connected to the outermost ends of the top plate 14. During operation, in cooperation with the structural setting of the top plate 14, after the drive wheels 15 push the top plate 14 out to be flush with the outlet of the sliding groove 8, the drive wheels 15 still remain inside the sliding groove 8 to ensure the subsequent transmission effect.

[0040] As Figure 6As shown, compared with the first comparative example, another implementation manner of the present invention is as follows: Limit rods 26 are fixedly installed at both the upper and lower ends of the top plate 14, and limit grooves are formed on the inner wall of the sliding groove 8. The limit rods 26 are slidably connected to the limit grooves. During operation, the arrangement of the limit rods 26 can limit the top plate 14 in the sliding groove 8, reducing the problem that the driving wheel 15 drives the top plate 14 to protrude outwards too much, resulting in the movement of the unfolding frame 12 being blocked.

[0041] During operation, a photovoltaic power station needs to transfer the generated electric energy to an energy storage device for power storage. Generally, a large number of photovoltaic panels are installed in a photovoltaic power station, resulting in a large number of complex power transmission lines connecting the photovoltaic panels to the energy storage device. During circuit maintenance or inspection, the crowded lines are not only unfavorable for troubleshooting but also waste a lot of time for maintenance personnel. Through the setting of the input socket 3, the lines of the photovoltaic panels are docked with a number of transmission seats 4. When circuit maintenance or troubleshooting is required, only six transmission seats 4 in the same row need to be slid and unfolded to one side, and then the five guide rails 9 are slid and unfolded vertically along the sliding rods 10, so that the lines that were originally gathered together can be fully unfolded, separating the power transmission lines, effectively facilitating the line troubleshooting and maintenance process. After the troubleshooting is completed, the several transmission seats 4 can be slid back to the corner of the input socket 3 to gather the lines, reducing the occupied space of the device and improving the practicality of the device; during operation, with the setting of the unfolding frame 12, when unfolding the horizontal transmission seats 4, only the outermost transmission seat 4 needs to be pulled. As the outermost transmission seat 4 moves, the five unfolding frames 12 will rotate and unfold in sequence. When the five unfolding frames 12 are fully opened and parallel, the five transmission seats 4 can be arranged equidistantly on the guide rails 9. Through this setting, the line unfolding process becomes convenient, and at the same time, the final unfolding distribution is also the most reasonable, further facilitating the line troubleshooting and maintenance. At the same time, under this setting, thirty transmission seats 4 are pre-determined at the beginning. Some can be used first, and some can be left unused. As the construction and addition of photovoltaic panels progress, the lines can be supplemented to the unused transmission seats 4, facilitating the subsequent line connection process; during operation, when the transmission seat 4 needs to be unfolded, only the power component needs to be activated to push the top plate 14 outwards, and the unfolding frame 12 can be pushed out of the chute 8, enabling the transmission seat 4 to be unfolded horizontally without manual operation. And the setting that part of the unfolding frame 12 is located in the chute 8 makes it impossible for the guide rail 9 to move up and down before the unfolding frame 12 is unfolded. Through this setting, the unfolding of the transmission seat 4 becomes orderly and neat, reducing the problem of line entanglement during the unfolding process; during operation, after a row of transmission seats 4 is unfolded, two electric wheels 19 are activated to rotate, causing the two electric wheels 19 to move closer to the center, so that the two folding plates 20 are lifted upwards from the central rotating shaft three 21. Through this setting, the adjacent guide rails 9 can be separated from each other, and with the setting of the power component, the unfolding process of the transmission seat 4 becomes fully mechanized without manual operation; during operation, when the transmission seat 4 needs to be unfolded for circuit maintenance, first activate the electric telescopic rod 25 to retract the connecting seat 16, cutting off the power supply between the transmission seat 4 and the storage battery 6. When the maintenance is completed and all the connecting seats 16 return to the corner, then activate the electric telescopic rod 25 to push the connecting seat 16 outwards, inserting the connecting seat 16 into the connecting seat 22 to energize the transmission seat 4, making the circuit completely disconnected during the maintenance process. At the same time, the physical connection can fix the connecting seats 16 piled up in the corner, reducing the effect of the continuous swinging of the transmission seat 4 under the pulling of the wire;During operation, through the setting of the card slot 23, the upper rail 17 and the lower rail 18 stably hold the transfer seat 4, enabling the transfer seat 4 to slide stably. The setting of the sliding ball 24 can reduce the friction generated when the transfer seat 4 slides, making the movement of the transfer seat 4 smoother. During operation, when the unfolding frame 12 needs to be pushed outwards, the driving wheel 15 is started to drive the top plate 14 to move, so that the unfolding frame 12 can be smoothly pushed out of the chute 8, and the six transfer seats 4 are horizontally unfolded. Moreover, as the guide rail 9 moves upwards, there is no space for the unfolding frame 12 to retract, so that the unfolding frame 12 is always in the unfolded state. During operation, in cooperation with the arc setting on the outer side of the rotating shaft II 13, the friction between the outer side of the rotating shaft II 13 and the outer side of the top plate 14 can be reduced. At the same time, when the guide rail 9 drives the unfolding frame 12 to rise, the smooth setting on the outer side of the rotating shaft II 13 can also make the rotating shaft II 13 slide more easily. The setting of the magnet material and the metal material enables, when finally returning, only by starting the driving wheel 15 to drive the top plate 14 to move inwards, and under the adsorption effect, the unfolding frame 12 can be pulled into the bent state. Through this kind of setting, a fully mechanized unfolding and returning process of the transfer seat 4 is realized.;
