Description

Technical Field

[0001] This invention relates to the field of photovoltaic module technology, and in particular to a buried solar photovoltaic module. Background Technology

[0002] Solar photovoltaic (PV) modules are the core and most important component of a solar power generation system. Their function is to convert solar energy into electrical energy, which is then either stored in a battery bank or used to power a load. A typical PV module consists of a glass layer, an EVA layer, battery cells, and a TPT layer laminated together to form a block-shaped component. An aluminum alloy frame is then fitted around the module and secured with corner keys to enhance its overall strength.

[0003] As an important component of photovoltaic modules, burying the battery pack underground can better protect its safety. Although burying the battery pack underground can prevent the dangers of sun and rain, it is not only difficult to remove it for maintenance, but it may also cause moisture problems. To address these issues, we propose a buried solar photovoltaic module. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the difficulty in removing and maintaining buried battery packs, and the potential for moisture damage. Therefore, this invention proposes a buried solar photovoltaic module.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An underground solar photovoltaic module includes a battery pack, a protective box, and a cover. The protective box has a top opening design, and the cover is hinged to the top of the protective box. The protective box has a moving cavity inside, and two sliding grooves are respectively formed on the two opposite side walls of the moving cavity. A dustproof mechanism is installed on the upper part of the sliding groove, and a placement mechanism is installed on the lower part of the sliding groove. The battery pack is placed in the placement mechanism, and a blocking mechanism is installed on the two side walls of the sliding groove.

[0007] The present invention further defines the technical solution as follows:

[0008] Preferably, the placement mechanism includes a protective frame, a placement plate, two upper sliding rods and two lower sliding rods. The placement plate is fixedly connected to the inner bottom wall of the protective frame. The battery pack is installed on the top wall of the placement plate. The two upper sliding rods are respectively installed at the upper ends of the protective frame, and the two lower sliding rods are respectively installed at the lower ends of the protective frame. The upper sliding rods and lower sliding rods are slidably connected to the inside of the slide groove.

[0009] Preferably, activated carbon is installed at the bottom of the motion chamber, and the protective frame is located above the activated carbon.

[0010] Preferably, the dustproof mechanism includes a baffle, a disc, a support rod, a torsion spring, a rubber cover, and two side rods. The two side rods are respectively installed on both sides of the baffle and are slidably connected to the inner wall of the groove. The rubber cover is installed on the bottom wall of the baffle. A limiting groove is formed on the top wall of the baffle. The support rod is rotatably connected to the bottom wall of the limiting groove. The other end of the support rod is fixedly connected to the bottom wall of the disc. The torsion spring is installed between the limiting groove and the disc.

[0011] Preferably, the sidewall of the disc has two first finger holes and the sidewall of the baffle has two second finger holes. In the initial position, the angle between the first finger holes and the second finger holes is 90°.

[0012] Preferably, the blocking mechanism includes a stop bar, a pad, an elliptical ball, a moving rod, a protrusion, and a spring. Placement holes and rotation holes are respectively provided on both sides of the slide groove. The stop bar is rotatably connected to the side wall of the rotation hole. The pad is installed on the bottom wall of the placement hole. A moving cavity is provided on the side wall of the slide groove. The elliptical ball is slidably connected to the side wall of the moving cavity. The moving rod is slidably connected to the side wall of the moving cavity. The protrusion is installed on the side wall of one end of the moving rod, and the protrusion abuts against the side wall of the elliptical ball. The other end of the moving rod passes through the side wall of the pad. The spring is fixedly connected to the side wall of the moving rod.

[0013] Preferably, a notch is provided on the front side wall of the box cover, a lock is installed inside the box cover, and a lock hole for the lock is provided on the inner wall of the notch.

[0014] Preferably, the moving rod is U-shaped, with one end of the moving rod passing through the pad being arc-shaped, and the spring is fixedly connected to one U-shaped bottom end of the moving rod.

[0015] Preferably, the rubber cover is hollow, and a vent hole is provided at the bottom of the rubber cover.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The battery pack is placed on a horizontal platform, which makes it more stable. Since the battery pack is not in direct contact with the side wall of the protective box, and the bottom is filled with activated carbon for dehumidification, the battery pack buried underground is safer and more stable. The triangular cover on the top of the protective box can also play a good role in drainage, effectively protecting the battery pack from rainwater erosion.

[0018] 2. In addition to the triangular lid, a dustproof mechanism is installed inside the protective box. This serves as a second layer of protection against rain and also prevents external dust from entering the protective box. To remove the dustproof mechanism, you need to rotate the disc so that the first finger hole and the second finger hole coincide, and then use your fingers to pull out the dustproof mechanism. The rubber cover at the bottom of the baffle can play a certain sealing role when the baffle is put back, protecting the safety of the battery pack.

[0019] 3. When the battery pack needs to be inspected, the protective frame can be pulled up along the slide groove. The sliding rod at the bottom of the protective frame can then lift the stop bar. As the sliding rod passes through, the stop bar will fall onto the pad under gravity. At this point, the staff can release the protective frame, and the battery pack and protective frame will fall onto the stop bar. Due to the presence of the pad, the protective frame can be stably placed on the stop bar. After the inspection is completed, simply lift the sliding rod up again to squeeze the elliptical ball. When the sliding rod leaves the elliptical ball, the moving rod will move upward under the action of the spring, thereby pushing the stop bar upward and causing the stop bar to fall back into the rotating hole.

Detailed Implementation

[0026] 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.

[0027] Reference Figure 1-5 An underground solar photovoltaic module includes a battery pack 1, a protective box 2 and a box cover 3. The protective box 2 has a top opening design. The box cover 3 is hinged to the top of the protective box 2. A notch 14 is opened on the front side wall of the box cover 3. A lock is installed inside the box cover 3. A lock hole 15 of the lock is installed on the inner wall of the notch 14. The inwardly recessed lock hole 15 can ensure the security of the lock. The lock can also ensure that the photovoltaic module cannot be opened by unauthorized persons.

[0028] The protective box 2 has a moving chamber inside, and activated carbon 8 is installed at the bottom of the moving chamber. The protective frame 601 is located above the activated carbon 8. The activated carbon 8 can dehumidify and effectively protect the safety of the battery pack 1.

[0029] Two sliding grooves 4 are respectively opened on the two opposite side walls of the motion cavity. A dustproof mechanism 500 is installed on the upper part of the sliding grooves 4. The dustproof mechanism 500 includes a baffle 501, a disc 502, a support rod 503, a torsion spring 504, a rubber cover 505, and two side rods 506. Two first finger holes 10 are opened on the side wall of the disc 502, and two second finger holes 11 are opened on the side wall of the baffle 501. In the initial position, the angle between the first finger holes 10 and the second finger holes 11 is 90°. To remove the dustproof mechanism 500, the disc 502 needs to be rotated so that the first finger holes 10 and the second finger holes 11 coincide, and then the dustproof mechanism 500 can be pulled out with a finger.

[0030] Two side rods 506 are respectively installed on both sides of the baffle 501. The two side rods 506 are slidably connected to the inner wall of the slide groove 4. The rubber cover 505 is installed on the bottom wall of the baffle 501. The rubber cover 505 is hollow and has a vent hole 16 at the bottom. The rubber cover 505 at the bottom of the baffle 501 can play a certain sealing role when the baffle 501 is pushed back to protect the safety of the battery pack 1. The vent hole 16 can play a certain pressure relief role to prevent excessive pressure.

[0031] A limiting groove 9 is provided on the top wall of the baffle 501. The support rod 503 is rotatably connected to the bottom wall of the limiting groove 9. The other end of the support rod 503 is fixedly connected to the bottom wall of the disc 502. The torsion spring 504 is installed between the limiting groove 9 and the disc 502. The torsion spring 504 can make the disc 502 reset better.

[0032] A placement mechanism 600 is installed at the lower part of the slide 4. The placement mechanism 600 includes a protective frame 601, a placement plate 602, two upper sliding rods 603 and two lower sliding rods 604. The placement plate 602 is fixedly connected to the inner bottom wall of the protective frame 601. The battery pack 1 is installed on the top wall of the placement plate 602. The two upper sliding rods 603 are respectively installed at the upper two ends of the protective frame 601, and the two lower sliding rods 604 are respectively installed at the lower two ends of the protective frame 601. The upper sliding rods 603 and the lower sliding rods 604 are respectively slidably connected to the inside of the slide 4. The setting of the upper sliding rods 603 and the lower sliding rods 604 can make the protective frame 601 slide more smoothly in the slide 4.

[0033] Battery pack 1 is placed within placement mechanism 600. Two blocking mechanisms 700 are respectively installed on the side walls of the two slides 4. Each blocking mechanism 700 includes a stop bar 701, a pad 702, an elliptical ball 703, a moving rod 704, a protrusion 705, and a spring 706. Placement holes 12 and rotation holes 13 are respectively opened on both sides of the slides 4. The stop bar 701 is rotatably connected to the side wall of the rotation hole 13. The pad 702 is installed on the bottom wall of the placement hole 12. A motion cavity is opened on the side wall of the slides 4. The elliptical ball 703 is slidably connected to the side wall of the motion cavity, and the moving rod 704 is slidably connected to the side wall of the motion cavity. A protrusion 705 is installed on one side wall of the moving rod 704, and the protrusion 705 abuts against the side wall of the elliptical ball 703. The other end of the moving rod 704 passes through the side wall of the pad 702. The spring 706 is fixedly connected to the side wall of the moving rod 704. The moving rod 704 is U-shaped, and the end of the moving rod 704 that passes through the pad 702 is arc-shaped. The spring 706 is fixedly connected to the bottom end of the U-shape of the moving rod 704. The elastic force of the spring 706 allows the stop rod 701 to spring back from the pad 702 into the rotating hole 13, which is convenient for the protective frame 601 to return to its initial position after maintenance.

[0034] In this invention, when the battery pack 1 needs to be repaired, the staff first unlocks the box cover 3. After opening the box cover 3, the staff rotates the disc 502 and compresses the torsion spring 504 so that the first finger hole 10 on the surface of the disc 502 coincides with the second finger hole 11 on the surface of the baffle 501. By inserting a finger into the hole, the dustproof mechanism 500 can be easily pulled out.

[0035] After pulling out the dustproof mechanism 500, pull the upper end of the protective frame 601. By pulling the protective frame 601, the battery pack 1 is pulled up along the slide groove 4. The sliding bar 604 at the bottom of the protective frame 601 can lift the stop bar 701. When the sliding bar 604 passes, the stop bar 701 will fall onto the pad 702 under the action of gravity. At this time, the staff can release the protective frame 601, and the battery pack 1 and the protective frame 601 will fall onto the stop bar 701. Due to the presence of the pad 702, the protective frame 601 can be stably placed on the stop bar 701.

[0036] After maintenance, simply lift the sliding rod 604 upwards once more, causing it to press against the elliptical ball 703. When the sliding rod 604 leaves the elliptical ball 703, the elliptical ball 703 presses against the protrusion 705, which in turn moves the moving rod 704. The moving rod 704 then moves upwards under the action of the spring 706, causing the other end of the moving rod 704 to forcefully push the stop rod 701 upwards. This causes the stop rod 701 to fall back into the rotating hole 13. Since the rotating hole 13 has a certain inclination, the stop rod 701 does not fall down so easily. Therefore, the protective frame 601 has enough time to fall back to its original position. A slight shake of the protective box 2 is all it takes to make the stop rod 701 fall down, facilitating the next maintenance.
