Description

Technical Field

[0001] This application relates to the field of photovoltaic inverter technology, and in particular to a retractable rainproof and ventilated cover for a photovoltaic inverter. Background Technology

[0002] A photovoltaic (PV) inverter is a key component of a solar photovoltaic (PV) power generation system. Its main function is to convert the direct current (DC) generated by PV modules into alternating current (AC) so that it can be connected to the public power grid or directly supplied to local loads. PV inverters can monitor the PV power generation system in real time, including monitoring parameters such as voltage, current, and temperature. When abnormal conditions such as overvoltage, overcurrent, undervoltage, or overheating occur, timely protective measures such as shutdown and alarms are taken to ensure the safe and stable operation of the system.

[0003] Photovoltaic inverters are usually installed outdoors (such as on rooftops or at photovoltaic power station sites), directly exposed to the natural environment. Rainwater may cause the following problems: rainwater seeps into the interior, comes into contact with circuit boards, components, etc., causing short circuit faults, or even burning out the equipment; long-term damp environment will reduce the performance of insulation materials, increase the risk of leakage, and affect the safety of the system.

[0004] Existing photovoltaic (PV) inverters primarily achieve an IP65 or higher protection rating for their casings to prevent rainwater and dust from affecting internal components. However, under prolonged exposure to natural environmental conditions, the protection level of the casing gradually decreases over time, and may even fail. Therefore, to further prevent rainwater from impacting PV inverters and extend their lifespan, it is necessary to design a retractable rainproof and ventilated cover for PV inverters. Utility Model Content

[0033] Existing photovoltaic (PV) inverters primarily achieve an IP65 or higher protection rating for their casings to prevent rainwater and dust from affecting internal components. However, under prolonged exposure to natural environmental conditions, the protection level of the casing gradually decreases over time, and may even fail. Therefore, to further prevent rainwater from impacting PV inverters and extend their lifespan, it is necessary to design a retractable rainproof and ventilated cover for PV inverters.

[0034] In view of this, this application proposes a retractable rainproof and ventilated cover for a photovoltaic inverter.

[0035] In the embodiments of this application, reference is made to Figures 1 to 5 The aforementioned retractable rainproof and ventilated cover for photovoltaic inverters includes: a rainproof cover 1 disposed above the photovoltaic inverter 7; the first side of the rainproof cover 1 is mounted on the support structure 3 via a fixing mounting member 2; the second and third sides of the rainproof cover 1 are each provided with a first side plate 4; and the fourth side of the rainproof cover 1 is provided with a second side plate 5 opposite to the first side; the rainproof cover 1 includes a first rainproof plate 110 and a second rainproof plate 120; the second end of the first rainproof plate 110 overlaps the first end of the second rainproof plate 120 vertically; and multiple fixing fasteners 6 are provided on the outer side of the overlap between the first rainproof plate 110 and the second rainproof plate 120; the fixing fasteners 6 are used to clamp the first rainproof plate 110 and the second rainproof plate 120.

[0036] Specifically, the rain cover 1 is connected to the support structure 3 via the fixing mounting bracket 2. The first rain cover 110 and the second rain cover 120 achieve telescopic functionality through their overlapping portion. When it is necessary to adjust the coverage area of ​​the rain cover 1, the two plates are slid to change their overlap, and then locked by the outer fixing clips 6. The overlapping design of the two rain cover plates allows for length adjustment to adapt to photovoltaic inverters 7 of different sizes or installation spaces, reducing customization costs. The first side plate 4 and the second side plate 5 can block rainwater from the sides. The length can be adjusted without complicated tools, making it suitable for quick on-site installation. The overlapping structure, together with the clips, forms a physical barrier, effectively preventing rainwater penetration.

[0037] In this embodiment, the two first side plates 4 are fixedly connected to the first end of the first rainproof plate 110 and the second end of the second rainproof plate 120, respectively, and the two first side plates 4 are respectively perpendicular to the corresponding first rainproof plate 110 and second rainproof plate 120; the first side plates 4 are vertically fixed to both ends of the rainproof plate and connected to the support structure 3 and the side of the inverter to form a rigid frame, which distributes the self-weight of the rainproof cover 1 and the external load, avoids deformation, and enhances the wind and rain resistance of the rainproof cover 1, making it suitable for complex outdoor environments; when the rainproof cover 1 is extended or retracted, the side plates move synchronously with the rainproof plate to ensure that the protective performance does not decrease when the coverage area is adjusted.

[0038] In this embodiment, both first side plates 4 are connected to the support structure 3 by fixing mounting parts 2, and both first side plates 4 are connected to the corresponding side of the photovoltaic inverter 7 by screws; the double connection improves structural stability and can withstand greater external forces.

[0039] In this embodiment, a ventilation window 410 is provided on the first side plate 4, and a louver 411 is fixedly installed inside the ventilation window 410. The louver 411 is fixed inside the ventilation window 410, and the tilt angle design allows air to flow along a specific path. At the same time, the gap between the louvers and the tilt direction form a physical barrier, using surface tension to prevent rainwater from entering, so that this structure can take into account both ventilation and rain protection.

[0040] In this embodiment, the second side plate 5 is divided into two parts. The first part is integrally formed with the first rainproof plate 110, and the second part is integrally formed with the second rainproof plate 120. The second side plate 5 is inclined towards the outside of the photovoltaic inverter 7. The integral design avoids leakage at the joints, improves the overall sealing performance, and allows rainwater to slide off along the inclined surface to avoid accumulation.

[0041] In this embodiment, a sealing strip 111 and a water-blocking strip 121 are provided between the overlapping area of ​​the first rainproof plate 110 and the second rainproof plate 120. The cross-section of both the sealing strip 111 and the water-blocking strip 121 is an arc-shaped structure. The sealing strip 111 is fixedly installed near the second end of the first rainproof plate, and the water-blocking strip 121 is fixedly installed near the first end of the second rainproof plate. The sealing strip 111 is made of rubber material, and the water-blocking strip 121 is made of plastic or rubber material. The sealing strip 111 fills the gap by compression deformation, forming the first line of defense. The water-blocking strip 121 intercepts residual moisture when the sealing strip 111 fails, preventing penetration. This design allows rainwater to be intercepted by the sealing strip 111 first, and the remaining moisture is further blocked by the water-blocking strip 121. The double seal can withstand the impact of heavy rain and effectively improve the protective effect.

[0042] In this embodiment, multiple fixing mounting components 2 are provided and evenly distributed between the rain cover 1 and the support structure 3. Each fixing mounting component 2 includes a mounting plate 210 and two parallel connecting plates 220. The two connecting plates 220 are vertically fixedly mounted on the mounting plate 210. The mounting plate 210 has multiple first through holes 211 for screws to pass through and connect to the support structure 3. The two connecting plates 220 also have multiple corresponding second through holes 221 for bolts to pass through and connect to the rain cover 1. When using the fixing mounting components 2, firstly, the rain cover 1 is inserted between the two connecting plates 220. Bolts are then inserted into the second through holes 221 and pass through the rain cover 1, thus fixing the connecting plates 220 to the rain cover 1. Then, screws are passed through the first through holes 211 to fix the mounting plate 210 to the support structure 3, thereby fixing the rain cover 1 to the support structure 3. The evenly distributed mounting components distribute the weight of the rain cover 1 across the support structure 3, avoiding single-point overload.

[0043] In this embodiment, the fixing buckle 6 is a structure integrally molded from elastic material. The cross-section of the fixing buckle 6 is U-shaped. The opening of the fixing buckle 6 is provided with two inwardly inclined clamping parts 601. A flexible strip 602 is provided in the middle of the fixing buckle 6 near the clamping parts 601. The flexible strip 602 is made of rubber material. The U-shaped fixing buckle 6 is inserted into the overlapping part of the rainproof plate through elastic deformation. The inclined clamping parts 601 provide initial biting force, and the flexible strip 602 enhances friction, preventing the clamping parts from forming scratches on the rainproof cover 1, while also playing a fixing and buffering role.

[0044] In this embodiment, the support structure 3 is a wall 310, and the first side of the rain cover 1 is installed on the wall 310 by a fixing bracket 2; the rain cover 1 is directly fixed to the wall 310 by the mounting bracket, which is suitable for wall-mounted photovoltaic inverters 7.

[0045] In the second embodiment of this application, reference is made to Figure 6The support structure 3 includes a support base plate 320 and a support vertical plate 330. The support vertical plate 330 is vertically fixed on the support base plate 320. A triangular reinforcing rib 340 is installed between the support vertical plate 330 and the support base plate 320. The photovoltaic inverter 7 is set on the support base plate 320. The first side of the rain cover 1 is installed on the support vertical plate 330 through a fixing mounting piece 2. The support base plate 320 and the vertical plate form an L-shaped bracket. The reinforcing rib 340 enhances the anti-overturning ability and is suitable for ground-mounted photovoltaic inverters 7.

[0046] This application's technical solution utilizes a rain cover mounted above a photovoltaic inverter. The first side of the rain cover is fixed to a supporting structure via a mounting bracket. First side plates are provided on the opposite second and third sides of the rain cover, and a second side plate is provided on the opposite fourth side. The rain cover includes a first rainproof plate and a second rainproof plate. The second end of the first rainproof plate overlaps the first end of the second rainproof plate. Multiple fixing clips are provided on the outer side of the overlap between the first and second rainproof plates to hold the first and second rainproof plates in place. The rain cover is connected to the supporting structure via the mounting bracket. The first and second rainproof plates achieve a telescopic function through their overlapping portion. When the coverage area of ​​the rain cover needs to be adjusted, the two plates are slid to change their overlap, and then locked in place by the outer fixing clips. The overlapping design of the two rainproof panels allows for length adjustment to accommodate photovoltaic inverters of different sizes or installation spaces, reducing customization costs. The first and second side panels can block rainwater from the sides. This design allows for length adjustment without complicated tools, making it suitable for quick on-site installation. The overlapping structure, together with the snap fasteners, forms a physical barrier that effectively prevents rainwater penetration.
