Description

Technical Field

[0001] This invention relates to the field of photovoltaic system technology, and in particular to a portable photovoltaic energy storage box. Background Technology

[0002] Photovoltaic systems are clean energy systems that convert solar energy into electrical energy. They are mainly divided into three types: stand-alone, grid-connected, and hybrid. Their applications cover household electricity, traffic signals, agricultural irrigation, and large-scale power plant construction. Photovoltaic energy storage boxes are an important component of these systems.

[0003] Existing photovoltaic energy storage boxes are divided internally by multiple partitions to separate various components. These components generate heat during operation. Although equipped with a cooling and temperature control system, if the battery pack spontaneously combusts due to a malfunction, the system cannot quickly extinguish the fire. Furthermore, the time required for staff to respond to an alarm and handle the emergency leaves multiple components inside the storage box at high risk, potentially leading to incalculable losses. Therefore, these energy storage boxes have low safety performance and pose safety hazards. Summary of the Invention

[0016] The portable photovoltaic energy storage box provided by this invention has the following technical effect: when a fire breaks out inside the box and the high-temperature fusible rope melts, the lower plate is pressed and the upper plate is unfolded. The squeezed push-out airbag instantly resets, and the push-out airbag quickly pushes out the fire extinguishing powder inside the storage cavity. The fire extinguishing powder flows along the lifting plate and is quickly distributed in the air between the two partitions to complete the initial fire extinguishing. Then, the push-out airbag comes into contact with each puncture needle, and the puncture needle punctures the push-out airbag. The gas inside the middle air plate and the two push-out airbags rushes out from the puncture hole, pushing out the fire extinguishing powder inside the storage cavity again, realizing a secondary fire extinguishing operation and avoiding the spread of fire that would cause serious damage to the internal structure of the box.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] The portable photovoltaic energy storage box disclosed in this invention is mainly used in existing photovoltaic energy storage boxes. These boxes are internally divided by multiple partitions to separate various components. During operation, all components inside the energy storage box generate heat. Although equipped with a cooling and temperature control system, if the battery pack spontaneously combusts due to a malfunction, the cooling and temperature control system cannot quickly extinguish the fire. Furthermore, it takes time for staff to respond to the alarm and handle the emergency. This results in all components inside the energy storage box being at high risk, leading to incalculable losses. The energy storage box has low safety performance and presents potential safety hazards.

[0031] Reference Figures 1-11A portable photovoltaic energy storage box includes a box body 1. The box body 1 has a double-extension emergency mechanism 7 evenly spaced inside. The double-extension emergency mechanism 7 includes a partition 701, which is fixedly connected to the bottom and top inner walls of the box body 1. A storage cavity is formed at the top of the partition 701. An installation hole is formed above the partition 701 in the box body 1, communicating with the storage cavity. An intermediate air plate 710 is fixedly connected inside the installation hole, and the intermediate air plate 710 is fixed on both sides inside the storage cavity. The device is connected to an ejector airbag 712, and a connecting hole 718 is opened at the connection between the intermediate air plate 710 and the ejector airbag 712. The partition 701 has fixing holes on both sides of the storage cavity. The upper wall of the fixing hole is connected to an unfolding upper plate 707 by a hinge, and the lower wall of the fixing hole is connected to a pressing lower plate 706 by a hinge. The unfolding upper plate 707 has a matching groove at equal intervals on one side. The pressing lower plate 706 has a pressing block 719 fixedly connected at equal intervals on the top. The pressing block 719 is adapted to the matching groove.

[0032] In a specific application scenario, when a fire breaks out inside the housing 1 and the high-temperature fusible rope 705 is melted, the lower plate 706 is pressed to separate from the upper plate 707. The squeezed ejection airbag 712 instantly resets, and the ejection airbag 712 quickly ejects the extinguishing powder located inside the storage cavity, causing the extinguishing powder to flow along the lifting plate 711 and quickly distribute itself in the air between the two partitions 701, completing the initial fire extinguishing. Then, the ejection airbag 712 comes into contact with each puncture needle 717, and the puncture needle 717 punctures the ejection airbag 712. The gas inside the middle air plate 710 and the two ejection airbags 712 then rushes out from the puncture holes, once again ejecting the extinguishing powder inside the storage cavity, realizing a secondary fire extinguishing operation. This prevents the fire from spreading and causing serious damage to the internal structure of the housing 1, thus improving the emergency protection effect of the housing 1.

[0033] Specifically, after the upper plate 707 is separated from the lower plate 706, the pull spring 702 pulls the upper plate 707 to prevent it from deflecting downwards due to its weight, which would obstruct the spraying of the extinguishing powder. At the same time, when the extinguishing powder is pushed out, the various dispersing rods 713 at the upper plate 707 divide the extinguishing powder to prevent it from clumping together and reducing the extinguishing effect.

[0034] It should be noted that if the high-temperature fusible rope 705 does not break, but the temperature sensor 9 detects that the internal temperature of the box 1 is too high, the back-end control terminal will control the electric telescopic rod 13 to drive the cutter 14 to cut the high-temperature fusible rope 705. Then, the electric telescopic rod 13 will drive the cutter 14 to quickly reset, and the fire extinguishing powder will be pushed out to extinguish the existing flames. This double protection ensures the safety of the inside of the box 1.

[0035] Reference Figures 1-7In a preferred embodiment, the partition 701 has side blocks 720 fixedly connected to both ends of one side of the connection between the upper unfolding plate 707 and the lower pressing plate 706. High-temperature fusible ropes 705 are fixedly connected at equal distances to the opposite sides of the two side blocks 720. The high-temperature fusible ropes 705 are in contact with the upper unfolding plate 707 and the lower pressing plate 706. The upper unfolding plate 707 has a feeding hole on one side near the top. The inside of the feeding hole is filled with a sealing plate 708. The side of the upper unfolding plate 707 above the feeding hole is fixedly connected to a mating rail 715. A sliding pressure plate 716 is slidably connected inside the mating rail 715. The sliding pressure plate 716 is in contact with the sealing plate 708.

[0036] Reference Figures 4-7 In a preferred embodiment, an integrated rod 704 is fixedly connected to the inner top wall of the housing 1 near the upper unfolding plate 707, and a tension spring 702 is fixedly connected at equal intervals to the bottom of the integrated rod 704. One end of the tension spring 702 is fixedly connected to one side of the upper unfolding plate 707. A dispersing rod 713 is fixedly connected at equal intervals to the side of the upper unfolding plate 707 facing the airbag 712. A lifting plate 711 is fixedly connected to the side of the lower pressing plate 706 facing the airbag 712. Two pump ring frames 709 are fixedly connected to the top of the middle air plate 710, and an air pump 703 is fixedly connected inside each of the two pump ring frames 709. The air supply end of the air pump 703 is connected to the inside of the middle air plate 710 through a pipe. An installation rod 714 is fixedly connected to both sides of the storage cavity near each airbag 712. A puncture needle 717 is fixedly connected at equal intervals to the side of the installation rod 714 facing the airbag 712.

[0037] Reference Figure 6 In a preferred embodiment, mounting rings 10 are fixedly connected to both sides of the partition 701, and temperature sensors 9 are fixedly connected inside both mounting rings 10. Support plates 12 are fixedly connected to both sides of the partition 701 below the high-temperature fuse rope 705. Electric telescopic rods 13 are fixedly connected at equal intervals to the top of the support plates 12. The output ends of multiple electric telescopic rods 13 are fixedly connected to the same blade plate 11. Cutting blades 14 are fixedly connected at equal intervals to the top of the blade plate 11.

[0038] Reference Figure 1 and Figure 3 In a preferred embodiment, a dust cover 3 is fixedly connected to the top of the box body 1, and the dust cover 3 is located above a plurality of intermediate air plates 710. Air inlets 8 are opened on both sides of the dust cover 3. A dustproof inclined plate 2 is fixedly connected to one side of the dust cover 3 located around the air inlets 8. A box door 4 is connected to one side of the box body 1 at equal intervals via hinges. A placement groove is opened on the bottom inner wall of the box body 1 located below a plurality of partitions 701. A cooling temperature control mechanism 6 is provided on the placement groove.

[0039] Reference Figure 2 , Figure 8 , Figure 9 , Figure 10 and Figure 11 In a preferred embodiment, hoisting auxiliary mechanisms 5 are symmetrically distributed on both sides of the box body 1, and the hoisting auxiliary mechanism 5 includes an auxiliary outer frame 501. The auxiliary outer frame 501 is fixedly connected to the side wall of the box body 1. Positioning slide rods 502 are fixedly connected at equal intervals on the top inner wall of the auxiliary outer frame 501. A lifting ring 511 is slidably connected to each positioning slide rod 502. The same lifting rod 517 is fixedly connected to the outer wall of the multiple lifting rings 511. A buffer spring rod 514 is sleeved at equal intervals on each positioning slide rod 502. A contact block 513 is fixedly connected to the bottom end of each buffer spring rod 514.

[0040] Specifically, during the hoisting of the container 1, the hook is threaded onto the lifting ring 512 and simultaneously through the fastening ring frame 519, ensuring close contact between the airbag 521 and the hook. The electric telescopic rod 523 is adjusted to drive the compression ball 522 to compress the lower part of the airbag 521, making the contact between the airbag 521 and the hook tighter and improving the firmness of the connection between the hook and the lifting ring 512. During the process of lifting the container 1, the lifting ring 511 compresses the buffer spring rod 514, and multiple sets of buffer spring rods 514 are compressed to the top, thereby providing buffer protection for the lifting and lowering of the container 1. The installation of the hoisting auxiliary mechanism 5 facilitates the carrying and transfer of the container 1.

[0041] It should be noted that when the lifting rod 517 slides on the positioning slide rod 502, the traction rope 503 drives the push pressure column 505 to move, and the push pressure column 505 squeezes the adjacent buffer ramp 507, causing the buffer ramp 507 to deflect. Under the action of the linkage push rod 524, each buffer ramp 507 deflects. When the box 1 is about to make contact with the ground, each buffer ramp 507 will contact the ground first. The buffer spring rod 516 cooperates with the buffer ramp 507 to realize the impact buffer when the box 1 falls, protecting the box 1.

[0042] Reference Figures 8-11 In a preferred embodiment, lifting rod 517 has two ends of lifting ring 512 fixedly connected to each other, and the top of each lifting ring 512 is fixedly connected to a fixing block 518. The outer side wall of the fixing block 518 is fixedly connected to a fastening ring frame 519, which is located above the lifting ring 512. The inner side wall of the fastening ring frame 519 is fixedly connected to a fitting airbag 521. The outer side wall of the fastening ring frame 519 near the bottom is fixedly connected to a lower abutment ring 520. The inner side wall of the lower abutment ring 520 is circumferentially distributed with electric telescopic rods 523. The output end of each electric telescopic rod 523 is fixedly connected to a compression ball 522.

[0043] Reference Figure 8and Figure 9 In a preferred embodiment, two mounting slots 504 are symmetrically opened at the bottom of the housing 1, and deflection shafts 508 are fixedly connected at equal intervals in the two mounting slots 504. A buffer inclined plate 507 is sleeved on the outer wall of each deflection shaft 508. The buffer inclined plates 507 located inside the two mounting slots 504 are symmetrically distributed. A fixing rod 515 is fixedly connected to the top inner wall of the mounting slot 504 above the buffer inclined plate 507. A buffer spring rod 516 is fixedly connected at equal intervals at the bottom of the fixing rod 515. The bottom end of the buffer spring rod 516 is fixedly connected to the buffer inclined plate 507. A linkage push rod 524 is fixedly connected to the downward-facing inclined surface of each buffer inclined plate 507. The linkage push rod 524 is in contact with the adjacent buffer inclined plate 507.

[0044] Reference Figure 9 In a preferred embodiment, a telescopic connecting rod 506 is fixedly connected to the inner wall of the mounting groove 504 on the side away from the lifting rod 517, and a push pressure column 505 is fixedly connected to one end of the telescopic connecting rod 506. Two traction ropes 503 are fixedly connected to the push pressure column 505. Each buffer slope 507 has a through hole, and the traction rope 503 passes through the corresponding through hole. One end of each traction rope 503 is fixedly connected to the bottom of the lifting rod 517. A shaft frame 509 is fixedly connected to both ends of each traction rope 503 in the housing 1. A traction wheel 510 is sleeved on the shaft frame 509, and the traction rope 503 passes through the traction wheel 510.

[0045] Working principle: When the container 1 is moved to the designated point, the hook is threaded onto the lifting ring 512 and simultaneously through the fastening ring frame 519, ensuring close contact between the airbag 521 and the hook. Adjusting the electric telescopic rod 523 causes the compression ball 522 to compress the area below the airbag 521, making the contact between the airbag 521 and the hook even tighter and improving the stability of the connection between the hook and the lifting ring 512. During the upward movement of the container 1, as the lifting rod 517 slides on the positioning slide rod 502, the traction rope 503 pushes the pressure... The column 505 moves, pushing the pressure column 505 to squeeze the adjacent buffer ramps 507, causing the buffer ramps 507 to deflect. Under the action of the linkage push rod 524, each buffer ramp 507 deflects, transporting the box 1 to the designated point. When the box 1 is about to make contact with the ground, each buffer ramp 507 contacts the ground first. The buffer spring rod 516 cooperates with the buffer ramps 507 to achieve impact buffering when the box 1 lands. In the event of a fire during normal use of the box 1... At that moment, the high-temperature fusible rope 705 melts, pressing the lower plate 706 to separate from the upper plate 707. The squeezed ejection airbag 712 instantly resets, and the ejection airbag 712 rapidly ejects the extinguishing powder located inside the storage chamber, causing the extinguishing powder to flow along the lifting plate 711, thereby quickly distributing it in the air above the two partitions 701, completing the initial fire extinguishing. Then, the ejection airbag 712 comes into contact with each puncture needle 717, and the puncture needle 717 punctures the ejection airbag 712, thus extinguishing the fire between the middle air plate 710 and the two ejection airbags. The gas inside 712 rushes out through the puncture hole, pushing out the extinguishing powder inside the storage chamber again, thus achieving a secondary fire extinguishing operation. At the same time, if the high-temperature fusible rope 705 does not break, the temperature sensor 9 detects that the internal temperature of the box 1 is too high. Then, the back-end control terminal controls the electric telescopic rod 13 to drive the cutter 14 to cut the high-temperature fusible rope 705. Then, the electric telescopic rod 13 drives the cutter 14 to quickly reset, and the extinguishing powder is pushed out to extinguish the existing flames. This double protection ensures the safety of the inside of the box 1.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
