A leak-proof photovoltaic power generation array and its installation method

Abstract

This invention provides a leak-proof photovoltaic power generation array and its installation method, including mounting legs, connecting hinges, horizontal support rods, vertical support rods, movable connecting components, support frames, photovoltaic panels, vertical sealing seats, vertical sealing mechanisms, secondary water receiving channels, drainage channels, and connecting water pipes. Each row of photovoltaic panels in this invention has a secondary water receiving channel at its bottom, and all secondary water receiving channels are connected to the drainage channel. Since rainwater from each row of photovoltaic panels is collected and discharged through the corresponding secondary water receiving channel, the rainwater flow rate on the surface of each row of photovoltaic panels is the same during rain, preventing rainwater accumulation. The gaps between adjacent photovoltaic panels in the same row are sealed by the vertical sealing mechanism, enhancing the sealing performance and ensuring that rainwater can only flow downwards into the secondary water receiving channels. Because the movable connecting components are detachably fixed to the horizontal support rods, the positions of the vertical support rods and vertical sealing seats can be adjusted according to the width of the photovoltaic panels.

Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation equipment technology, specifically to a leak-proof photovoltaic power generation array and its installation method. Background Technology

[0002] Photovoltaic panels can directly convert solar energy into electrical energy. Compared with traditional thermal power generation and nuclear power generation, they have advantages such as permanence, cleanliness, and flexibility, and are therefore widely used. Photovoltaic panels can be placed in various places, such as rooftops, unused ground surfaces, or hillsides. When photovoltaic panels are placed on rooftops, rainwater will flow onto the roof through the panels during rainy days. Because of the presence of photovoltaic panels, the roof's drainage function is obstructed, and water easily accumulates on the roof. If it is not drained in time, it will cause roof leaks. Moreover, rainwater is easily carried by the wind to the bottom of the photovoltaic panels. Since the bottom of most photovoltaic panels is the wiring point, rainwater leaking to the bottom can easily enter the interior of the photovoltaic panels, causing damage.

[0003] The patent application CN108039854A discloses a new type of leak-proof photovoltaic power generation array and installation method. By covering the upper edge of the upper row of photovoltaic panels with the upper edge of the lower row of photovoltaic panels, rainwater can flow along the upper surface of the upper row of photovoltaic panels into the upper surface of the lower row of photovoltaic panels and eventually into the drain pipe. However, in application, since the water flows over the surface of the photovoltaic panels, the bottom photovoltaic panel is exposed to the largest flow of rainwater, making it prone to damage. In addition, when encountering a large amount of rain, the covering area between the upper and lower rows of photovoltaic panels is prone to water seepage, causing damage to the photovoltaic panels. Furthermore, the frame of the photovoltaic panels in this structure is directly fixed to the lower support frame through connectors, and cannot be adjusted according to the width of the photovoltaic panels, resulting in poor applicability.

A pneumatic spring is fixed at the bottom of the secondary tank body, and the lower support plate is fixed on the pneumatic spring and abuts against the longitudinal support rod. A water pipe connector communicating with the interior of the secondary tank body is also fixed at the bottom of the secondary tank body for installing and connecting water pipes.

[0012] Preferably, the secondary water receiving tank also includes a sealing plate, and a sealing plate is fixed on the upper end surface of the side sealing plate and the outer side surface of the secondary tank that is in contact with the photovoltaic panel.

[0013] Preferably, the movable connecting assembly comprises an extrusion frame, a lower fixed frame, an upper fixed frame, a guide block, a retaining rod, a retaining ring, an extrusion block, and a retaining spring.

A retaining spring is fitted on the retaining rod, with one end abutting against the retaining ring and the other end abutting against the inner side wall of the extrusion frame.

[0014] Preferably, the side wall of the transverse support rod that contacts the movable connecting assembly is provided with a fixing hole that matches the size of the abutment rod.

[0015] The present invention also provides an installation method for a leak-proof photovoltaic power generation array, the installation method being applicable to the above-mentioned leak-proof photovoltaic power generation array, comprising:

[0016] S1: Fix the bottom of the mounting leg to the required installation position. Adjust the distance between the longitudinal support rod and the longitudinal sealing seat according to the width of the photovoltaic panel. The longitudinal sealing seat is set between the longitudinal support rods of adjacent photovoltaic panels in the same row.

[0017] S2: Install the outermost photovoltaic panel in the first row of photovoltaic panels, fix the photovoltaic panel on the support frame, and then install the photovoltaic panel next to it. Fix the longitudinal sealing mechanism on the longitudinal sealing seat between the two photovoltaic panels that have been installed, and clamp the sides of the two photovoltaic panels that meet into the longitudinal sealing seat. Continue to install the photovoltaic panel next to the second photovoltaic panel, and repeat this process until the entire row of photovoltaic panels is installed.

[0018] S3: Install the outermost photovoltaic panel in the second row, and insert the auxiliary water inlet between the photovoltaic panels in the adjacent row and column.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] This invention features a secondary water receiving trough at the bottom of each row of photovoltaic panels. All secondary water receiving troughs are connected to drainage troughs. Therefore, during rain, rainwater flowing over each row of photovoltaic panels flows into the secondary water receiving troughs below and is then discharged through the drainage troughs on both sides. Since the rainwater from each row of photovoltaic panels is collected and discharged by the corresponding secondary water receiving trough, the rainwater flow rate on the surface of each row of photovoltaic panels is the same, preventing rainwater accumulation and reducing the rainwater flow rate on the surface of the photovoltaic panels. Furthermore, the gaps between adjacent photovoltaic panels in the same row are sealed by a longitudinal sealing mechanism, enhancing the sealing performance and ensuring that rainwater can only flow downwards into the secondary water receiving troughs. Since the longitudinal support rod and the longitudinal sealing seat are detachably fixed to the transverse support rod through movable connecting components, their positions can be adjusted according to the width of the photovoltaic panels, making it highly adaptable.

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example:

[0033] Please see Figures 1 to 7 The present invention provides a technical solution:

[0034] A leak-proof photovoltaic power generation array includes mounting legs 1, connecting hinges 2, horizontal support rods 3, vertical support rods 4, movable connecting components 5, support frame 6, photovoltaic panels 7, vertical sealing seats 8, vertical sealing mechanisms 9, secondary water receiving troughs 10, drainage troughs 11, and connecting water pipes 12, wherein:

[0035] The transverse support rod 3 is provided with at least two sets. The upper end of the mounting leg 1 is fixed with a connecting hinge 2. The transverse support rod 3 is fixed on the connecting hinge 2. The mounting leg 1 can rotate freely around the connecting hinge 2 to adjust the support angle, which facilitates the installation of the transverse support rod 3. The longitudinal support rod 4 is equipped with movable connecting components 5 at both ends. The movable connecting components 5 are detachably fixed on the transverse support rod 3. The longitudinal support rod 4 is installed on the upper end of the transverse support rod 3 through the movable connecting components 5.

[0036] The movable connecting assembly 5 consists of an extrusion frame 501, a lower fixed frame 502, an upper fixed frame 503, a guide block 504, a retaining rod 505, a retaining ring 506, an extrusion block 507, and a retaining spring 508. The lower fixed frame 502 is fixed to the side of the extrusion frame 501 and is engaged with the transverse support rod 3. The upper fixed frame 503 is fixed to the upper end of the lower fixed frame 502 and is engaged with the longitudinal support rod 4 or the longitudinal sealing seat 8. The guide block 504 is fixed to the inner side of the extrusion frame 501 near the lower fixed frame 502. Two parallel retaining rods 505 are installed inside the extrusion frame 501. One end of the retaining rod 505 passes through the guide block 504 and the side wall of the extrusion frame 501 and extends into the lower fixed frame 502, while the other end passes through the side wall of the extrusion frame 501 and extends to the outside.

[0037] A retaining ring 506 is fixed in the middle of the retaining rod 505. A vertical moving groove 51 is provided on the extrusion block 507. The retaining rod 505 passes through the moving groove 51. The extrusion block 507 has a regular triangular prism structure, with its inclined surface abutting against the retaining ring 506 and its vertical surface abutting against the guide block 504. A retaining spring 508 is sleeved on the retaining rod 505. One end of the retaining spring 508 abuts against the retaining ring 506, and the other end abuts against the inner side wall of the extrusion frame 501. A fixing hole matching the size of the retaining rod 505 is provided on the side wall where the transverse support rod 3 contacts the movable connecting assembly 5.

[0038] When the lower fixing bracket 502 is engaged with the transverse support rod 3, the retaining rod 505 can penetrate into the fixing hole under the elastic force of the retaining spring 508, thereby fixing the movable connecting component 5 to the transverse support rod 3 and fixing the longitudinal support rod 4 or the longitudinal sealing seat 8 to the transverse support rod 3. When the pressing block 507 is pushed upward on the transverse support rod 3, the retaining ring 506 will press the retaining rod 505 to move, causing the retaining rod 505 to be pulled out from the fixing hole. The longitudinal support rod 4 or the longitudinal sealing seat 8 can be quickly removed, realizing the quick disassembly and assembly and position adjustment of the longitudinal support rod 4 or the longitudinal sealing seat 8. The position of the longitudinal support rod 4 and the longitudinal sealing seat 8 can be adjusted according to the width of the photovoltaic panel 7, which has strong applicability. The longitudinal support rod 4 is inclined downward, so that the photovoltaic panel 7 is also inclined downward, allowing rainwater to flow down along the photovoltaic panel 7. A support frame 6 is fixed on the longitudinal support rod 4, and the bottom of the photovoltaic panel 7 is fixed on the support frame 6.

[0039] At least one of the photovoltaic panels 7 is arranged in a grid pattern. A longitudinal sealing seat 8 is provided on the lower end of the transverse support rod 3 at the joint of adjacent photovoltaic panels 7 in the same row. The longitudinal sealing seat 8 is installed on the upper end of the transverse support rod 3 via a movable connecting assembly 5. A longitudinal sealing mechanism 9 is installed on the longitudinal sealing seat 8 to seal the joint of adjacent photovoltaic panels 7 in the same row. The longitudinal sealing mechanism 9 includes a lower sealing frame 901, a moving frame 903, an upper pressure spring 904, an upper sealing plate 905, a fixing screw 906, and a longitudinal sealing plate 907. Multiple strip-shaped sliding grooves 81 are provided on the side of the longitudinal sealing seat 8. The lower sealing frame 901 is inverted T-shaped, and multiple hinge seats 902 are fixed to the lower end of the lower sealing frame 901. The lower end of the 02 is provided with two V-shaped motion frames 903. The upper end of each motion frame 903 is hinged in the hinge seat 902, and the lower end is locked in the sliding groove 81. The upper end of the motion frame 903 can rotate in the hinge seat 902, and the lower end can slide in the sliding groove 81. The two motion frames 903 are connected by an upper pressure spring 904. The upper end of the lower sealing frame 901 is provided with an upper sealing plate 905. The fixing screw 906 passes through the upper sealing plate 905 and connects to the lower sealing frame 901. The side of the photovoltaic panel 7 is locked between the lower sealing frame 901 and the upper sealing plate 905. The upper sealing plate 905 is installed by the fixing screw 906, which is easy to disassemble and convenient to lock the side of the photovoltaic panel 7 between the lower sealing frame 901 and the upper sealing plate 905.

[0040] During use, the lower sealing frame 901 and the upper sealing plate 905 hold the side of the photovoltaic panel 7 in place to ensure a seal. The upper pressure spring 904 applies a closing elastic force to the two moving frames 903. When the photovoltaic panel 7 presses down on the lower sealing frame 901, the two moving frames 903 will gradually separate. However, under the action of the upper pressure spring 904, the two moving frames 903 always push the lower sealing frame 901 upward through the hinge seat 902, so that it can always be in close contact with the side of the photovoltaic panel 7 to ensure the sealing effect. A longitudinal sealing plate 907 is fixed on the contact side of the lower sealing frame 901, the upper sealing plate 905 and the photovoltaic panel 7. The longitudinal sealing plate 907 further improves the sealing performance of the lower sealing frame 901, the upper sealing plate 905 and the side of the photovoltaic panel 7, so that the gap between adjacent photovoltaic panels 7 can be firmly sealed, enhancing the sealing performance. This allows rainwater to flow downward along the photovoltaic panel 7, preventing rainwater from seeping into the lower end from the gap between the two photovoltaic panels 7.

[0041] A secondary water inlet trough 10 is fitted between adjacent photovoltaic panels 7 in the same row. The lower end of the secondary water inlet trough 10 abuts against the longitudinal support rod 4. The secondary water inlet trough 10 includes a secondary trough body 1001, side sealing plates 1002, side baffles 1003, a gas spring 1004, a lower support plate 1005, a water pipe connector 1006, and a sealing plate 1007. Side sealing plates 1002 are fixed to both sides of the secondary trough body 1001. The side sealing plates 1002 are fitted onto the lower end face of the photovoltaic panel 7. The side of the photovoltaic panel 7 abuts against the outer side of the secondary trough body 1001. The side sealing plates 1002 ensure a tight connection between the secondary water inlet trough 10 and the side of the photovoltaic panel 7, preventing rain from entering. Water seeps in from the connection between the photovoltaic panel 7 and the secondary water inlet trough 10. The two ends of the secondary trough 1001 are provided with side baffles 1003 protruding from their surfaces. The side baffles 1003 prevent rainwater inside the secondary trough 1001 from flowing out from the sides. A gas spring 1004 is fixed to the bottom of the secondary trough 1001. The lower support plate 1005 is fixed on the gas spring 1004. The lower support plate 1005 abuts against the longitudinal support rod 4. The gas spring 1004 provides upward elastic force to support the side sealing plate 1002, so that it can be tightly attached to the lower end face of the photovoltaic panel 7, ensuring the sealing between the side sealing plate 1002 and the lower end face of the photovoltaic panel 7.

[0042] The bottom of the sub-tank 1001 is also fixed with a water pipe connector 1006 communicating with its interior for installing a connecting water pipe 12. The water pipe connector 1006 facilitates the installation of the connecting water pipe 12. A sealing plate 1007 is fixed on the upper end face of the side sealing plate 1002 and the outer side face of the sub-tank 1001 that is in contact with the photovoltaic panel 7. The sealing plate 1007 further improves the sealing degree between the sub-water tank 10 and the side of the photovoltaic panel 7. Drainage channels 11 are fixed at both ends of the transverse support rod 3. Multiple sub-water tanks 10 are connected in series by connecting water pipes 12, and the sub-water tanks 10 at both ends are connected to the drainage channels 11 by connecting water pipes 12. Each row Each photovoltaic panel 7 has a secondary water receiving trough 10 at its bottom. All secondary water receiving troughs 10 are connected to drainage troughs 11. Therefore, when it rains, the rainwater flowing over each row of photovoltaic panels 7 will flow into the secondary water receiving trough 10 below and then be discharged through the drainage troughs 11 on both sides. Since the rainwater of each row of photovoltaic panels 7 will be received and discharged by the corresponding secondary water receiving trough 10, the rainwater flow on the surface of each row of photovoltaic panels 7 is the same, which will not cause rainwater accumulation and reduce the rainwater flow on the surface of photovoltaic panels 7. Moreover, the gaps between adjacent photovoltaic panels 7 in the same row are sealed by the longitudinal sealing mechanism 9 to enhance the sealing performance, so that rainwater can only flow downward into the secondary water receiving trough 10.

[0043] Please see Figure 8 The present invention also provides an installation method for a leak-proof photovoltaic power generation array, the installation method being applicable to the aforementioned leak-proof photovoltaic power generation array, comprising:

[0044] S1: Fix the bottom of the mounting leg 1 to the required installation position, and adjust the distance between the longitudinal support rod 4 and the longitudinal sealing seat 8 according to the width of the photovoltaic panel 7. The longitudinal sealing seat 8 is set between the longitudinal support rods 4 of adjacent photovoltaic panels 7 in the same row.

[0045] S2: Install the outermost photovoltaic panel 7 in the first row of photovoltaic panels 7, fix the photovoltaic panel 7 on the support frame 6, and then install the photovoltaic panel 7 next to it. Fix the longitudinal sealing mechanism 9 on the longitudinal sealing seat 8 between the two photovoltaic panels 7 that have been installed, and lock the sides of the two photovoltaic panels 7 that meet into the longitudinal sealing seat 8. Continue to install the photovoltaic panel 7 next to the second photovoltaic panel 7, and repeat this process until the entire row of photovoltaic panels 7 is installed.

[0046] S3: Install the outermost photovoltaic panel 7 in the second row of photovoltaic panels 7, and clip the auxiliary water inlet trough 10 between the photovoltaic panels 7 in the adjacent row and column. Then repeat the installation method of the whole row of photovoltaic panels 7 in step S2 to install the second row of photovoltaic panels 7. Repeat this process until all rows of photovoltaic panels 7 are installed.

[0047] S4: Fix the drainage trough 11 at both ends of the horizontal support rod 3, then connect the adjacent secondary water receiving troughs 10 through the connecting water pipe 12, and then connect the secondary water receiving troughs 10 at the edge of each row to the drainage trough 11 through the connecting water pipe 12.
