Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of sunrooms, specifically to a sunroom roof structure. Background Technology
[0002] With the development of residential photovoltaic distributed power stations, more and more rural residential rooftops have become potential photovoltaic power generation targets. Many rural residential rooftops or other commercial building rooftops mostly adopt flat roof designs, and there is a general demand to make full use of these rooftops to realize photovoltaic power generation.
[0003] A photovoltaic (PV) sunroom consists of a steel frame with PV panels installed on top. Because the PV panels are installed in a spliced manner, directly using them as the roof would result in gaps at the joints, compromising rain protection. The traditional approach is to build a single roof for rain shelter, but this is costly. Therefore, this application provides a low-cost sunroom roof structure that achieves rain protection. Utility Model Content
[0004] Based on the above description, this utility model provides a sunroom roof structure to solve the problem of high cost of achieving rainproof function by laying an entire roof.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:
[0006] This application provides a sunroom roof structure, and the technical solution adopted is as follows:
[0007] A sunroom roof structure, comprising:
[0008] Roof frame;
[0009] A photovoltaic roof is installed on the top of the roof frame. The photovoltaic roof includes multiple sets of photovoltaic modules. Each photovoltaic module includes multiple photovoltaic units that are evenly spaced along the length of the roof and the multiple sets of photovoltaic modules are spaced along the width of the roof.
[0010] A horizontal water trough is provided between any two adjacent sets of photovoltaic modules. The horizontal water trough is located below the gap between the corresponding two adjacent sets of photovoltaic modules and extends along the length of the gap. The horizontal water trough is connected to the roof frame.
[0011] In each group of photovoltaic modules, a vertical water trough is provided between any two adjacent photovoltaic units. The vertical water trough is located below the gap between the corresponding two adjacent photovoltaic units and is arranged along the length of the gap. The vertical water trough is connected to the roof frame. The vertical water trough located between two adjacent horizontal water troughs is connected at both ends to the two adjacent horizontal water troughs.
[0012] Preferably, the photovoltaic roof is a double-sloped roof, and the length direction of the roof is parallel to the ridge. The horizontal water trough and the vertical small water trough are both set parallel to the slope.
[0013] Preferably, it also includes a longitudinal water channel, which comprises two sections located on the two side slopes respectively. The sections of the longitudinal water channel located on the two side slopes are parallel to the longitudinal small water channels on the corresponding slopes. The longitudinal water channel is located below the transverse water channel and connected to the roof frame. The longitudinal water channel and the transverse water channel are intersected, and the transverse water channel has a drainage hole at the bottom of the intersection with the longitudinal water channel.
[0014] Preferably, eaves gutters are provided at the eaves on both sides of the photovoltaic roof, the eaves gutters are parallel to the horizontal gutters, the eaves gutters are connected to the roof frame, and the two ends of the vertical gutters are respectively connected to the two eaves gutters.
[0015] Preferably, the roof frame includes multiple horizontal beams, which are parallel to the length direction of the roof and are spaced apart along the width direction of the roof. The longitudinal small water trough is located above the horizontal beams and is connected to the horizontal beams through connecting components.
[0016] Preferably, the connecting assembly includes a pressure plate, a limiting plate, and a U-bolt. The pressure plate is located above the longitudinal small water tank, the limiting plate is located below the crossbeam, and the U-bolt passes through the pressure plate and is fitted onto the crossbeam. Both ends of the U-bolt are connected to the limiting plate, so that the pressure plate presses the longitudinal small water tank tightly onto the crossbeam.
[0017] Preferably, the plurality of transverse water channels include transverse ridge water channels and transverse slope water channels. The cross-section of the transverse slope water channel is U-shaped and the opening faces upward. The side of the transverse slope water channel near the eaves is in contact with the bottom surface of the photovoltaic unit in the photovoltaic module near the eaves in the two adjacent sets of photovoltaic modules.
[0018] Preferably, the side of the transverse slope water trough closest to the eaves can elastically deform in the vertical direction.
[0019] Compared with the prior art, the technical solution of this application has at least the following beneficial technical effects:
[0020] This application utilizes horizontal and vertical drainage channels to channel water leaking from the gaps between two sets of photovoltaic modules into the horizontal channels. Specifically, water leaking from the gaps between adjacent photovoltaic units spaced apart along the width of the roof falls into the horizontal channels. Within each set of photovoltaic modules, water leaking from the gaps between two adjacent photovoltaic units falls into the vertical channels. Similarly, water leaking from the gaps between adjacent photovoltaic units spaced apart along the length of the roof falls into the vertical channels. Therefore, all rainwater leaking from the gaps between the photovoltaic units in the photovoltaic roof falls into the channels. The vertical channels located between two adjacent horizontal channels are connected at both ends to these two channels, allowing water to drain into the horizontal channels. The vertical channels located along the width of the roof can extend beyond the roof's coverage area, and the horizontal channels can also extend beyond the roof's coverage area to discharge rainwater around the sunroom, thus achieving a rainproof function for the roof. Furthermore, drainage channels only need to be installed at the gaps between the photovoltaic units on the photovoltaic roof, resulting in a lower cost compared to installing an entire roof.

[0033] Reference Figure 1 and Figure 2 As shown in the figure, this application provides a sunroom roof structure, including a roof frame 1 and a photovoltaic roof 2.
[0034] The photovoltaic roof 2 is laid on the top of the roof frame 1. The photovoltaic roof 2 includes multiple sets of photovoltaic modules. Each photovoltaic module includes multiple photovoltaic units 21 that are evenly spaced along the length of the roof and spaced along the width of the roof.
[0035] Specifically, the photovoltaic unit 21 is in the shape of a rectangular plate, and all the photovoltaic units 21 that make up the photovoltaic roof 2 are arranged in a rectangular array.
[0036] Reference Figure 2 As shown, to achieve the roof's rainproof function, a horizontal water trough 3 is provided between any two adjacent sets of photovoltaic modules. The horizontal water trough 3 is located below the gap between the corresponding two sets of photovoltaic modules and extends along the length of the gap. The horizontal water trough 3 is connected to the roof frame 1. In each set of photovoltaic modules, a vertical small water trough 4 is provided between any two adjacent photovoltaic units 21. The vertical small water trough 4 is located below the gap between the corresponding two adjacent photovoltaic units 21 and extends along the length of the gap. The vertical small water trough 4 is connected to the roof frame 1, and the vertical small water trough 4 located between two adjacent horizontal water troughs 3 has its two ends connected to the two adjacent horizontal water troughs 3.
[0037] With the above setup, water leaking from the gaps between adjacent photovoltaic units 21 spaced apart along the length of the roof falls into the longitudinal small water channels 4. Therefore, all rainwater leaking from the gaps between the photovoltaic units 21 in the photovoltaic roof 2 falls into the water channels. The longitudinal small water channels 4 located between two adjacent transverse water channels 3 drain water into the transverse water channels 3. The longitudinal small water channels 4 located along the width of the roof can extend beyond the roof coverage area, and the two ends of the transverse water channels 3 can also extend beyond the roof coverage area to discharge rainwater around the sunroom, thereby achieving the roof's rainproof function. Drainage channels only need to be installed at the gaps between the photovoltaic units 21 in the photovoltaic roof 2, which is less costly than laying the entire roof.
[0038] Reference Figure 1 and Figure 2 As shown, in order to quickly drain rainwater from the roof, in this embodiment, the photovoltaic roof 2 is a double-sloped roof, and the length direction of the roof is parallel to the ridge. The horizontal water channels 3 and the longitudinal small water channels 4 are both set parallel to the slope. Correspondingly, among the multiple horizontal water channels 3, the ones located on the ridge are horizontal ridge water channels, and the ones located on the slope are horizontal slope water channels.
[0039] Reference Figure 2 and Figure 3As shown, a longitudinal water trough 5 is further provided. The longitudinal water trough 5 includes two sections located on the two sides of the slope. The sections of the longitudinal water trough 5 located on the two sides of the slope are parallel to the longitudinal small water troughs 4 on the corresponding slope. The longitudinal water trough 5 is located below the transverse water trough 3 and connected to the roof frame 1. The longitudinal water trough 5 and the transverse water trough 3 are intersected. The transverse water trough 3 has a drainage hole 31 at the bottom of the intersection with the longitudinal water trough 5.
[0040] With this setup, the longitudinal small water trough 4 drains into the transverse water trough 3. The rainwater in the transverse water trough 3 is further discharged into the longitudinal medium water trough 5 through the drainage hole 31, and finally discharged along the longitudinal medium water trough 5 to the outside of the roof coverage area. The two ends of the transverse water trough 3 can be closed, and the rainwater is finally discharged to both sides of the roof slope through the longitudinal medium water trough 5.
[0041] Reference Figure 1 Figure 2 As shown, furthermore, eaves gutters 6 are respectively provided at the eaves on both sides of the photovoltaic roof 2. The eaves gutters 6 are parallel to the horizontal gutters 3. The eaves gutters 6 are connected to the roof frame 1. The two ends of the vertical central gutters 5 are respectively connected to the two eaves gutters 6.
[0042] Reference Figure 2 As shown, specifically, the two ends of the longitudinal small gutter 4 near the eaves are connected to the roof gutter 6 and the adjacent transverse gutter 3, respectively. The roof gutter 6 receives rainwater discharged from the longitudinal small gutter 4 and the longitudinal medium gutter 5. When installed, the roof gutter 6 is connected to the building's drainage system through a drain pipe. The drainage from the longitudinal small gutter 4 and the longitudinal medium gutter 5 flows into the roof gutter 6, and the roof drainage is finally discharged into the building's drainage system through the roof gutter 6 and the drain pipe, thus avoiding rainwater being discharged onto the roof and accumulating around the roof.
[0043] In this embodiment, the longitudinal small water trough 4, the transverse water trough 3, the longitudinal medium water trough 5, and the eaves water trough 6 are all U-shaped troughs with their openings facing upwards to collect leaking rainwater.
[0044] With the above configuration, the longitudinal small water trough 4, the transverse water trough 3, the longitudinal medium water trough 5, and the eaves water trough 6 constitute a complete roof drainage system, which can receive rainwater leaking from the gaps between the photovoltaic units 21 of the photovoltaic roof 2 and discharge it outside the roof area, giving the roof a rainproof function and the advantage of low cost.
[0045] During construction, the roof frame 1 is constructed first. Then, the longitudinal small water channels 4, transverse water channels 3, longitudinal medium water channels 5, and eaves water channels 6 are installed on the frame. Since there are fewer transverse water channels 3 and longitudinal medium water channels 5, their widths can be larger, thus requiring less precise positioning. After positioning, they can be fixed to the roof frame 1. However, there are more longitudinal small water channels 4. To reduce overall weight and cost, the width of the longitudinal small water channels 4 needs to be smaller. After rough positioning and installation, misalignment between the longitudinal small water channels 4 and the corresponding photovoltaic units 21 may occur during the subsequent installation of the photovoltaic roof 2. Therefore, the longitudinal small water channels 4 need to be position-adjustable.
[0046] Reference Figure 2 and Figure 4 As shown, specifically, the roof frame 1 includes multiple horizontal beams 11, which are parallel to the length direction of the roof. The multiple horizontal beams 11 are spaced apart along the width direction of the roof. The longitudinal small water trough 4 is located above the horizontal beams 11 and is connected to the horizontal beams 11 through the connecting component 7. The longitudinal small water trough 4 can move along the length and width directions of the roof.
[0047] In this embodiment, two crossbeams 11 are provided below each photovoltaic unit 21, and each longitudinal small water tank 4 is attached to the two crossbeams 11 below a photovoltaic unit 21.
[0048] Reference Figure 4 As shown, the connecting assembly 7 includes a pressure plate 71, a limiting plate 72, and a U-bolt 73. The pressure plate 71 is located above the longitudinal small water tank 4, the limiting plate 72 is located below the crossbeam 11, and the U-bolt 73 passes through the pressure plate 71 and is fitted onto the crossbeam 11. Both ends of the U-bolt 73 are connected to the limiting plate 72, so that the pressure plate 71 presses the longitudinal small water tank 4 tightly onto the crossbeam 11.
[0049] Both the pressure plate 71 and the limiting plate 72 are provided with holes for U-bolts 73 to pass through. During construction, after the longitudinal small water trough 4 is overlapped on the crossbeam 11, the pressure plate 71 is pressed onto the longitudinal small water trough 4, and the U-bolts 73 are first passed through the holes on the pressure plate 71 from top to bottom and fitted onto the crossbeam 11. Then, the two ends of the U-bolts 73 are passed through the limiting plate 72 and connected to the nuts. When the nuts are tightened, the longitudinal small water trough 4 is pressed onto the crossbeam 11 by the cooperation of the pressure plate 71 and the limiting plate 72, so as to restrict the movement of the longitudinal small water trough 4 through friction. When the nuts are loosened, the longitudinal small water trough 4 can be moved along its own length or along the length of the crossbeam 11 to adjust its position, so as to ensure that the gap between the longitudinal small water trough 4 and the corresponding adjacent photovoltaic unit 21 is aligned, and to prevent rainwater from leaking through the gap and falling into the interior space of the roof.
[0050] Furthermore, when rainwater flows along the slope of the photovoltaic roof 2, it leaks through the gaps between adjacent photovoltaic modules and tends to flow along the bottom surface of the photovoltaic units 21 in the photovoltaic modules near the eaves, thus deviating from the range of the horizontal water channel 3 and causing leaks. To solve this problem, in some embodiments, refer to... Figure 5 As shown, the side of the transverse sloping water trough near the eaves is in contact with the bottom surface of photovoltaic unit 21 in the photovoltaic module near the eaves of the two adjacent photovoltaic modules.
[0051] Reference Figure 5 As shown, specifically, the horizontal sloping water trough is designed with a larger vertical width on the side wall near the eaves so that the top edge of this side can fit against the bottom surface of the photovoltaic unit 21. In order to achieve the connection between the longitudinal small water trough 4 and the horizontal sloping water trough, a hole is opened on the side wall of the horizontal sloping water trough near the eaves so that the longitudinal small water trough 4 near this side can pass through. The width of the hole allows the longitudinal small water trough 4 to have a certain adjustment space along the length of the beam 11.
[0052] This design allows rainwater leaking through the gaps between adjacent photovoltaic modules to be blocked and diverted by the sidewalls of the transverse slope water channel as it flows along the bottom surface of the photovoltaic unit 21 in the photovoltaic module near the eaves. This prevents rainwater from leaving the transverse water channel 3 and causing leakage.
[0053] Reference Figure 5 As shown, furthermore, the transverse slope water channel is designed so that the side near the eaves can elastically deform vertically. Correspondingly, the height of the hole through which the longitudinal small water channel 4 passes must be able to meet the requirements of elastic deformation. Specifically, the side wall of this transverse slope water channel protrudes outward from the middle of the transverse slope water channel in the height direction, forming an arc segment. This arc segment allows the side of the transverse slope water channel near the eaves to elastically deform vertically, avoiding the situation where the side of the transverse slope water channel near the eaves cannot properly fit the bottom surface of the photovoltaic unit 21 due to the installation height error of the photovoltaic unit 21 during the installation of the photovoltaic roof 2, thus improving the adaptability of the transverse slope water channel.
[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
