Description

Technical Field

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

[0002] Small black tiles, a traditional Chinese clay tile, are a common type of tile in southern provinces and cities such as Zhejiang, Jiangsu, and Anhui. Traditionally fired clay small black tiles are brittle, have poor impact resistance, and are prone to breakage and leaks. In the residential photovoltaic field, the sloping roof type with small black tiles is quite common. Currently, this type of house uses a combination structure of an M-shaped water channel and a crossbeam. The M-shaped water channel has flanges on both sides of its bottom, with a pressure plate above the flanges, and U-bolts are used to fix the pressure plate to the flanges. Additionally, the side walls of the M-shaped water channel are bolted to the lateral parts of the crossbeam. This design has two major drawbacks:

[0003] 1. The weak flange structure of the M-shaped water tank is easily deformed by the pressure plate during installation and stepping, which increases the risk of instability during water tank installation.

[0004] 2. The existing M-shaped water tank is connected to the crossbeam with two bolts each, two U-bolts, which results in low construction efficiency.

[0005] These defects severely affect the reliability, durability, and ease of maintenance of the waterproofing solution, failing to fundamentally solve the persistent problem of water leakage in key areas of the small black tile roof, and may even introduce new risks of damage during the construction process.

[0006] Therefore, there is an urgent need to develop new waterproof joint solutions that are more reliable, more durable, easier to install, and more compatible with small black tiles. Utility Model Content

[0007] In view of the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a combination structure of crossbeam and M-shaped water tank and roof photovoltaic power station, which solves the problem that the weak flange structure of the existing M-shaped water tank is easily deformed by the pressure plate when it is installed and stepped on.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0009] First, a crossbeam and M-shaped water tank combination structure is provided, including an M-shaped water tank that is vertically and intersectingly fixed above a crossbeam. The M-shaped water tank includes side walls on both sides of the transverse direction, a recess in the middle of the transverse direction, and flanges extending outward from the bottom of the side walls. A crossbeam is provided above the M-shaped water tank at a position corresponding to the crossbeam. The crossbeam includes a crossbeam part supporting the top of the M-shaped water tank, two lateral parts corresponding to the outer sides of the two side walls of the M-shaped water tank, and a pressing edge pressed onto the flange. Fasteners are provided between the pressing edge and the flange.

[0010] Preferably, the lateral portion is provided with a puncture hole protruding towards the side wall, the puncture hole being in frictional contact with the side wall and conducting electricity.

[0011] Preferably, the lateral portion has two puncture holes arranged side by side along the longitudinal direction.

[0012] Preferably, the lateral portion has a groove, and the sidewall has a protrusion, the protrusion engaging with the groove.

[0013] Preferably, a reinforcing boss is provided at the middle of the top of the crossarm, and a fixing hole is provided on the reinforcing boss.

[0014] Preferably, the top lateral sides of the crossbeam are provided with fitting grooves, and the top lateral sides of the M-shaped water tank are provided with bosses, which fit into the fitting grooves.

[0015] Preferably, the crossarm is a sheet metal part; and / or, the fastener is an internal hex bolt.

[0016] In addition, a rooftop photovoltaic power station is provided, including the aforementioned crossarm and M-shaped water tank combination structure.

[0017] Preferably, a hook is provided between the beam and the roof.

[0018] Furthermore, the hook includes a base plate, a support plate, and a bent portion disposed between the base plate and the support plate, and the crossbeam is mounted on the support plate.

[0019] The present invention adopts the above technical solution and has the following beneficial effects:

[0020] 1. The crossarm and M-shaped water tank combination structure consists of an M-shaped water tank and a crossarm. The crossarm is positioned corresponding to the crossbeam, supporting the photovoltaic modules and connecting to the pressure block assembly, which secures the photovoltaic modules. Additionally, the crossarm includes two lateral portions located on the outer sides of the two side walls of the M-shaped water tank, enhancing its structural strength and preventing deformation. Furthermore, the pressure plate is pressed onto the flange, and fasteners, such as common bolts, are used for fixation. This eliminates the need for a pressure plate, solving the problem of existing M-shaped water tanks' weak flange structure being easily deformed by pressure plates during installation and foot traffic.

[0021] Since fasteners are only provided between the crossbeam and the M-shaped water tank between the pressure edge and the flange, U-bolts are not required. Furthermore, bolts are not used to fix the two side walls of the M-shaped water tank to the two lateral parts. Therefore, the number of bolt connection points can be reduced, and construction efficiency can be improved.

[0022] 2. The lateral portion is provided with a puncture hole protruding into the side wall. The puncture hole makes frictional contact with the side wall and conducts electricity, thereby achieving conductive grounding of the crossbeam and the water tank. Moreover, the crossbeam is grounded, thus achieving overall conductive grounding.

[0023] 3. The lateral portion is provided with a groove, and the side wall is provided with a protrusion. The protrusion and the groove cooperate with each other. In this way, the structural strength of the lateral portion and the side wall is enhanced by the interlocking structure between them.

[0024] 4. The top transverse middle of the crossbeam is provided with a reinforcing boss, and the reinforcing boss is provided with a fixing hole. The fixing hole is connected to the pressure block bolt of the pressure block assembly. The reinforcing boss can avoid the strength reduction caused by the thin-walled opening at the fixing hole.

[0025] 5. Since the top horizontal sides of the crossbeam are provided with fitting grooves and the top horizontal sides of the M-shaped water tank are provided with bosses, the bosses fit into the fitting grooves, so that the crossbeam and the M-shaped water tank can be tightly combined into one unit.

[0026] 6. Because the crossarm is made of sheet metal, it can be customized and mass-produced in the factory, avoiding on-site cutting, ensuring on-site construction efficiency. Furthermore, the high structural strength of sheet metal ensures the reliability of the connections. Using sheet metal also reduces costs and offers advantages such as rust resistance and long service life. Fasteners are bolts, which are not only convenient but also reliable for fixing.

[0027] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and accompanying drawings. Attached Figure Description

[0045] In existing technologies, photovoltaic power stations installed on sloping roofs typically use photovoltaic modules arranged in a rectangular array. Combining existing technologies... Figure 8 As shown, the photovoltaic module 4 is fixed on the crossbeam 3, and an M-shaped water tank 1 is provided between two adjacent photovoltaic modules 4 in the horizontal direction. The M-shaped water tank 1 has an M-shaped cross-section, with side walls 11 on both sides in the horizontal direction, a recess 12 in the middle, and flanges 13 extending outward from the bottom of the side walls on both sides of the bottom. The flanges 13 are fixed on the crossbeam 3.

[0046] For solutions involving the installation of M-type sinks, such as Figures 1 to 10 As shown, this embodiment provides a crossarm and M-shaped water tank combination structure for use in rooftop photovoltaic power stations. A crossarm 2 is provided above the M-shaped water tank 1 at the position corresponding to the crossbeam. The crossarm 2 includes a crossarm part 22 supporting the top of the M-shaped water tank, two lateral parts 21 corresponding to the outer sides of the two side walls of the M-shaped water tank, and a pressing edge 23 pressed onto the flange. A fastener 24 is provided between the pressing edge 23 and the flange 13. The pressing edge 23 is provided with a through hole 231 for the fastener to pass through. Of course, the flange 13 is also provided with a corresponding through hole.

[0047] In this embodiment, the fastener is an internal hex bolt. The crossbeam 22 is positioned corresponding to the crossbeam, and its longitudinal length is approximately equal to or slightly less than the width of the crossbeam. It supports the photovoltaic module 4 and connects to the pressure block assembly 5, which secures the photovoltaic module 4. Additionally, the crossbeam includes two lateral portions located on the outer sides of the two side walls of the M-shaped water tank, enhancing the structural strength of the M-shaped water tank and preventing deformation. Furthermore, the pressure plate is pressed onto the flange, and fasteners, such as common bolts, are used for fixation. This eliminates the need for a pressure plate, solving the problem of the weak flange structure of existing M-shaped water tanks being easily deformed by pressure plates during installation and foot traffic.

[0048] Since fasteners are only provided between the crossbeam and the M-shaped water tank between the pressure edge and the flange, U-bolts are not required. Furthermore, bolts are not used to fix the two side walls of the M-shaped water tank to the two lateral parts. Therefore, the number of bolt connection points can be reduced, and construction efficiency can be improved.

[0049] In some embodiments, the lateral portion 21 is provided with puncture holes 211 protruding towards the sidewall. These puncture holes 211 make frictional contact with the sidewall 11 and conduct electricity. This achieves a conductive connection between the crossbeam and the water tank, and since the crossbeam is grounded, overall conductive grounding is achieved. Specifically, the lateral portion 21 has two puncture holes 211 arranged side-by-side along the longitudinal direction to increase the reliability of conductivity.

[0050] In some embodiments, the lateral portion 21 is provided with a groove 25, and the sidewall 11 is provided with a protrusion 15, the protrusion 15 engaging with the groove 25. This interlocking structure between the lateral portion and the sidewall enhances their structural strength.

[0051] In some embodiments, a reinforcing boss 221 is provided at the top transverse center of the crossarm 22, which can protrude both upwards and downwards simultaneously, or protrude from one side. The reinforcing boss 221 is provided with a fixing hole 224. The fixing hole is connected to the pressure block bolt of the pressure block assembly 5. Providing the reinforcing boss can prevent strength reduction caused by thin-walled openings at the fixing hole location.

[0052] Furthermore, the top lateral sides of the crossbeam 22 are provided with fitting grooves 222, and the top lateral sides of the M-shaped water tank are provided with bosses 14, which fit into the fitting grooves 222. This allows the crossbeam and the M-shaped water tank to be tightly integrated. In addition, a recessed groove 223 is also provided at the position where the top of the crossbeam meets the fitting groove 222 to enhance the overall structural strength of the crossbeam.

[0053] Preferably, the crossbeam 22 is a sheet metal part. Stainless steel or aluminum alloy is preferred, which can be customized and mass-produced in the factory, avoiding on-site cutting, ensuring on-site construction efficiency. Moreover, sheet metal parts have high structural strength, ensuring the reliability of the connection. Using sheet metal parts can reduce costs, and also has the advantages of rust resistance and long service life.

[0054] like Figure 10 As shown, a hook 6 is provided between the crossbeam 3 and the roof. The hook 6 includes a base plate 61, a support plate 62, and a bent portion 63 located between the base plate and the support plate. The crossbeam 3 is installed on the support plate. The base plate 61 can be fixed to the sloping roof with expansion bolts. The base plate extends longitudinally, and its extension length is greater than the width of the crossbeam. The crossbeam and the support plate are fixed with bolts. In addition, the bent portion 63 has a Z-shaped structure.

[0055] 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.
