Description

[Technical Field]

[0001] This utility model belongs to the field of photovoltaic technology, specifically relating to rooftop photovoltaic power stations. [Background Technology]

[0002] For rooftop photovoltaic (PV) power stations, the M-shaped water channel waterproofing bracket solution for sloping roofs has become the mainstream in the market. This solution involves installing longitudinal water channels, typically M-shaped channels, between adjacent rows of PV modules. By installing smaller horizontal channels and a ridge cover, rainwater is prevented from entering the building, thus improving the waterproofing. However, the installation of the smaller channels and ridge cover requires on-site connection to the M-shaped channels using self-tapping screws or anchors, demanding high-level construction skills. Poor waterproofing at the ridge cover and anchor points can lead to leaks, affecting the waterproofing of the subsequent power station brackets, resulting in numerous customer complaints, maintenance difficulties, and impacting farmers' daily lives and the company's brand image. Furthermore, the separate installation of the ridge cover and smaller channels takes a long time and requires high-quality work from the construction team, with the risk of improper installation leading to missing or incomplete bolts. Finally, in areas with heavy snowfall during winter, waterproofing solutions are often used. However, snow easily accumulates on roof ridges and in small water tanks, where it freezes and reduces the waterproofing effect of the water tanks, increases the load, creates safety hazards, and can even shade the north-facing slopes. [Utility Model Content]

[0003] To address the shortcomings of existing technologies, the present invention aims to provide a rooftop photovoltaic power station and its ridge waterproof and snow-blocking components, thereby preventing snow from accumulating and freezing at the ridge and in the water tank, which would significantly reduce the waterproofing effect of the water tank.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] Firstly, a roof ridge waterproofing and snow-blocking component is provided. Photovoltaic module arrays are installed on both sides of the sloping roof ridge, and a longitudinal water channel is provided between the gaps of two adjacent rows of photovoltaic modules. The roof ridge waterproofing and snow-blocking component includes a roof ridge cover plate covering the roof ridge, snow-blocking cover plates on both sides of the roof ridge cover plate, a filter structure between the roof ridge cover plate and the snow-blocking cover plate, and a roof ridge water channel located below both sides of the roof ridge cover plate. The snow-blocking cover plate is arranged obliquely in the longitudinal direction, and its oblique lower end connects to the upper longitudinal end of the photovoltaic module array. The roof ridge cover plate has a structure that is high in the middle and low on both sides to guide rain and snow to both sides. The filter structure filters the flowing water and causes the filtered water to fall into the roof ridge water channel. The roof ridge water channel is connected to the longitudinal water channel.

[0006] Preferably, the ridge water trough includes a first inclined side disposed near the ridge, a second inclined side connected to the first inclined side, and a water-blocking side connected to the second inclined side. The inclination angle of the second inclined side is smaller than that of the first inclined side, and the inclination angle of the second inclined side is the same as that of the photovoltaic module array.

[0007] Preferably, the first inclined side is integrally connected to the ridge cover plate and is located below the filter structure so that the water flowing from the filter structure flows along the first inclined side.

[0008] Preferably, the water-blocking edge is provided with a flange.

[0009] Preferably, the water-blocking edge is provided with a notch, and the upper longitudinal end of the longitudinal water guide channel is connected to the roof ridge water channel through the notch.

[0010] Preferably, the second inclined side is fixed to the inclined beam with self-tapping screws.

[0011] Preferably, the ridge cover plate and the snow cover plate are integrally connected, and the filter structure is a filter hole opened at the junction of the ridge cover plate and the snow cover plate.

[0012] Preferably, the ridge cover plate has an inverted V-shape or an arch structure.

[0013] Preferably, the snow cover has an arc transition portion that connects with the filter structure.

[0014] In addition, a rooftop photovoltaic power station is also provided, including the aforementioned roof ridge waterproof and snow-proof component.

[0015] The present invention adopts the above technical solution and has the following beneficial effects:

[0016] 1. The ridge waterproofing and snow-blocking components can shield the space above the ridge, preventing rain and snow from directly entering the sloping roof and causing leakage risks. These components include a ridge cover plate, a filter structure between the ridge cover plate and the snow-blocking cover plate, and ridge drainage channels on both sides of the ridge cover plate. During rainy weather, rainwater flows from the center of the ridge cover plate to the sides, then through the filter structure into the drainage channels below, and finally into the longitudinal drainage channels. Additionally, snow-blocking cover plates are installed on both sides of the ridge cover plate, angled longitudinally, with their downward ends connecting to the upper longitudinal end of the photovoltaic module array. In winter, snow slides from the center of the ridge cover plate to the sides, then falls freely onto the photovoltaic panels due to the slope of the snow-blocking cover plates, achieving snow-blocking and water diversion, and preventing snow accumulation at the ridge.

[0017] Because the snow cover is set diagonally along the longitudinal direction and its downward end connects to the upper longitudinal end of the photovoltaic module array, it can prevent snow from falling into the roof ridge gutter and freezing, thus avoiding the risk of leakage.

[0018] 2. The ridge water trough includes a first inclined side near the ridge, a second inclined side connected to the first inclined side, and a water-retaining side connected to the second inclined side. The inclination angle of the second inclined side is smaller than that of the first inclined side. The first inclined side guides the water flowing from the filtration structure towards the second inclined side, which serves as the bottom of the ridge water trough. The water-retaining side forms the wall of the ridge water trough. Because the second inclined side is inclined, after the water flows from the first inclined side to the second inclined side, it will continue to flow towards the water-retaining side due to inertia, posing a risk of splashing. Therefore, the water-retaining side is equipped with a flange to prevent the water from impacting the trough wall and splashing out.

[0019] 3. The second inclined side has the same tilt angle as the photovoltaic module array, that is, the same tilt angle as the inclined beam and the longitudinal water guide channel, which facilitates the connection between the ridge water guide channel and the longitudinal water guide channel. Moreover, the second inclined side is attached to the inclined beam and is fixed to the inclined beam with self-tapping screws, so that the ridge waterproof and snow-proof components and the photovoltaic support are connected as a whole.

[0020] 4. The roof ridge waterproof and snow-blocking components are prefabricated in the factory. The first inclined side of the roof ridge water channel is integrally connected to the roof ridge cover plate, and the roof ridge cover plate is integrally connected to the snow-blocking cover plate. The filter structure consists of filter holes opened at the junction of the roof ridge cover plate and the snow-blocking cover plate, which reduces on-site installation steps, avoids on-site connection, and ensures on-site construction efficiency.

[0021] 5. The water-blocking edge is provided with a notch. The upper longitudinal end of the longitudinal water guide channel is inserted into the ridge water channel through the notch, and the joint can be waterproofed, so that the water in the ridge water channel flows to the longitudinal water guide channel.

[0022] 6. The ridge cover is an inverted V-shape or arched structure. This creates an inverted V-shape or arched guiding surface on the upper surface of the ridge cover. Because it is higher in the middle and lower on both sides, rainwater falling on the ridge cover can quickly flow to both sides, avoiding the risk of leakage caused by rainwater staying on the ridge cover. It also helps snow accumulated on the ridge cover to flow to both sides onto the snow cover.

[0023] 7. The snow cover is provided with an arc transition part that connects with the filter structure, so as to guide the snow from the ridge cover to the snow cover and avoid obstruction at the junction of the snow cover and the filter structure.

[0024] 8. The waterproof and snow-proof components are made of aluminum alloy plates or stainless steel plates, which are not only corrosion resistant, but also have high strength and long service life. At the same time, they can be mass-produced industrially, and the cost is not high. They are also relatively aesthetically pleasing.

[0025] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and accompanying drawings. [Attached Image Description]

[0035] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0036] Those skilled in the art will understand that, without conflict, the features in the following embodiments and implementations can be combined with each other.

[0037] The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. For example, terms such as "upper," "lower," "longitudinal," and "lateral," which indicate orientation or positional relationship, are based solely on the orientation or positional relationship shown in the accompanying drawings and are used only for the convenience of describing the invention and simplifying the description. They do not indicate or imply that the device / component referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention.

[0038] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0039] Reference Figures 1 to 7 As shown, this embodiment provides a rooftop photovoltaic power station. The roof of building 5 has sloping roof surfaces 51 on both sides of the ridge 52, and photovoltaic modules 2 are installed on both sides of the sloping roof surfaces 51. The photovoltaic modules 2 are fixed to photovoltaic brackets, which have inclined beams 3. The inclined beams 3 can be supported on the sloping roof surfaces 51 by hook components 4. On each sloping roof surface, several photovoltaic modules are arranged in an array and extend longitudinally upwards to a position close to the ridge. The photovoltaic modules on both sides of the ridge have spacing at the ridge. Typically, drainage structures are provided on both sides of the sloping roof surface. Taking a common structure as an example, a longitudinal water guide channel is set along the sloping extension direction of the roof surface and located between two adjacent rows of photovoltaic modules.

[0040] In this embodiment, a roof ridge waterproof and snow-blocking component 1 is installed at the ridge, which is connected to the upper longitudinal side of the photovoltaic module array on both sides of the sloping roof and covers the gap space at the ridge. The roof ridge waterproof and snow-blocking component 1 includes a ridge cover plate 11 covering the ridge, snow-blocking cover plates 12 on both sides of the ridge cover plate, a filter structure 13 between the ridge cover plate and the snow-blocking cover plate, and ridge water channels 14 on both sides below the ridge cover plate. The snow-blocking cover plate 12 is arranged obliquely in the longitudinal direction, and its oblique lower end is connected to the upper longitudinal end of the photovoltaic module array. The ridge cover plate 11 has a structure that is high in the middle and low on both sides to guide rain and snow to both sides. The filter structure 13 is used to filter the flowing water and let the filtered water fall into the ridge water channel 14. The ridge water channel 14 is connected to the longitudinal water channel.

[0041] The rooftop photovoltaic power station utilizes the aforementioned waterproof and snow-blocking components to shield the space above the roof ridge, preventing rain and snow from directly entering the sloping roof and causing leakage risks. During rainy weather, rainwater flows from the center of the ridge cover to both sides, then passes through a filtration structure into the ridge gutter below, and finally flows into the longitudinal drainage channel. Additionally, snow-blocking covers are installed on both sides of the ridge cover, angled longitudinally, with their downward ends connecting to the upper longitudinal end of the photovoltaic module array. In winter, snow slides from the center of the ridge cover to both sides, then freely falls onto the photovoltaic panel surface due to the slope of the snow-blocking covers, achieving snow-blocking and water diversion, and preventing snow accumulation at the ridge.

[0042] Because the snow cover is set diagonally along the longitudinal direction and its downward end connects to the upper longitudinal end of the photovoltaic module array, it can prevent snow from falling into the roof ridge gutter and freezing, thus avoiding the risk of leakage.

[0043] Understandably, the downward-sloping end of the snow cover is roughly flush with the vertical top of the photovoltaic module array to facilitate the snow sliding from the snow cover to the photovoltaic module array. Of course, the joint is not completely seamless, but even with small gaps, the snow is less likely to fall into the roof ridge gutter during the sliding process.

[0044] Specifically, the ridge water trough 14 includes a first inclined side 141 located near the ridge, a second inclined side 142 connected to the first inclined side, and a water-blocking edge 143 connected to the second inclined side. The inclination angle of the second inclined side is smaller than that of the first inclined side, and the inclination angle of the second inclined side is the same as that of the photovoltaic module array. The water-blocking edge 143 is provided with a flange 144. The first inclined side guides the water flowing from the filter structure to the second inclined side, which serves as the bottom of the ridge water trough. The water-blocking edge forms the wall of the ridge water trough. Since the second inclined side is inclined, after the water flows from the first inclined side to the second inclined side, it will continue to flow towards the water-blocking edge due to inertia, posing a risk of splashing. Therefore, the water-blocking edge is provided with a flange to prevent the water from impacting the trough wall and splashing out.

[0045] It is understandable that the C-side of the photovoltaic module frame is pressed against the bottom wall of the longitudinal water guide channel and the second inclined side. In the prior art, the C-side of the photovoltaic module frame extends inward, such as... Figure 2 As shown, the water-blocking edge 143 is located inside edge C, and the flange 144 is located on the upper side of edge C.

[0046] In this embodiment, the ridge waterproofing and snow-blocking component is a factory-prefabricated part. The first inclined side 141 is integrally connected to the ridge cover plate 11 and is located below the filter structure, so that the water flowing from the filter structure flows along the first inclined side. The ridge cover plate 11 is integrally connected to the snow-blocking cover plate 12. The filter structure 13 is a filter hole opened at the junction of the ridge cover plate and the snow-blocking cover plate, that is, the filter hole is directly processed at the junction of the ridge cover plate and the snow-blocking cover plate, without the need to set up a filter screen or other filter structure. The size and shape of the filter hole can be designed according to needs, such as the filter hole being a parallelogram, rectangle, etc. Therefore, it is convenient to integrally process the ridge waterproofing and snow-blocking component, reduce on-site installation steps, avoid on-site connection, and ensure on-site construction efficiency. In addition, it can be understood that the height of the ridge cover plate can be customized according to requirements. The height of the aforementioned roof ridge waterproofing and snow-blocking components is adjustable, covering most of the properties and improving the coverage of the solution. At the same time, compared with existing waterproofing solutions on the market, the integrated roof ridge waterproofing and snow-blocking components greatly improve the stability and safety of the water tank and power station, ensuring the profitability of the power station.

[0047] Furthermore, the water-blocking edge 143 has a notch corresponding to the longitudinal water guide channel, and the upper longitudinal end of the longitudinal water guide channel connects to the ridge water channel 14 through the notch. The connection point can be waterproofed, ultimately allowing water in the ridge water channel to flow into the longitudinal water guide channel.

[0048] Specifically, the second inclined side 142 is fixed to the inclined beam 3 with self-tapping screws. The second inclined side has the same tilt angle as the photovoltaic module array, that is, the same tilt angle as the inclined beam and the longitudinal water guide channel, which facilitates the connection between the ridge water guide channel and the longitudinal water guide channel. Moreover, the second inclined side fits against the inclined beam and is fixed to the inclined beam with self-tapping screws, so that the ridge waterproof and snow-proof component and the photovoltaic support are connected as a whole.

[0049] In addition, the snow cover 12 is provided with an arc transition portion 121 that connects with the filter structure 13. This facilitates the flow of snow from the ridge cover to the snow cover, avoiding obstruction at the junction of the snow cover and the filter structure.

[0050] Specifically, the ridge cover plate 11 has an inverted V-shape or an arched structure. It can also be any other shape, higher in the middle and lower on both sides. This creates an inverted V-shape or arched guiding surface on the upper surface of the ridge cover plate. Because of the higher middle and lower sides, rainwater falling on the ridge cover plate can quickly flow to both sides, preventing rainwater from lingering on the ridge cover plate and causing leakage risks. It also facilitates the flow of snow accumulated on the ridge cover plate to both sides onto the snow cover plate.

[0051] In this embodiment, the waterproof and snow-blocking component 1 is made of aluminum alloy plate or stainless steel plate. It is not only corrosion-resistant, but also has high strength, long service life, low cost, and is aesthetically pleasing.

[0052] The above description is merely a specific embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes, but is not limited to, the content described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of the utility model will be included within the scope of the claims.
