Description

Technical Field

[0001] The utility model belongs to the field of photovoltaic laminate installation, and particularly relates to a photovoltaic component locking mechanism. Background Art

[0002] At present, the newly installed photovoltaic capacity of China's large-scale ground power stations exceeds 95GW (megawatts), and the cumulative installed capacity exceeds 487.6GW (megawatts), and the photovoltaic stock is close to saturation. Therefore, major domestic photovoltaic companies have transferred the photovoltaic market to the rooftop distributed market with huge potential, continuously updated photovoltaic cells and their component technologies, and made early arrangements to occupy a larger share in the rooftop distributed market. In addition to the consideration of power generation, the current installation of rooftop distributed photovoltaic components also puts forward higher requirements for the safety performance and aesthetics of rooftop distribution. When installing photovoltaic components with frames on the roof, the conventional method of block installation is mainly based on the block pressing method, that is, the block pressing presses the adjacent photovoltaic components on the bracket, where the bracket is set on the roof. This installation method has the following disadvantages: Disadvantage 1. The block pressing is installed on the side of the frame (the contact area between the frames of adjacent photovoltaic components) and fixed on the bracket, so that there must be a position for the block pressing installation between the frames of adjacent photovoltaic components, that is, there is a certain interval between the frames of adjacent photovoltaic components, which wastes a part of the photovoltaic installed capacity to a certain extent. Disadvantage 2. The block pressing needs to be installed separately after the photovoltaic component is placed on the bracket. The installation process is relatively complicated and increases certain labor costs. Disadvantage three: The photovoltaic modules installed by pressing blocks need to press the pressing blocks to the front of the photovoltaic frame (the front of the photovoltaic module), which affects the appearance.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1As shown, the utility model proposes a photovoltaic component locking mechanism, including: a photovoltaic component 1, a fixing bracket 2 and a self-locking component 3, the photovoltaic component 1 includes a photovoltaic laminate 11 and a frame 12, the photovoltaic laminate 11 is embedded in the frame 12, the back of the frame 12 has a connecting portion 121, a first fixing hole 1211 is provided on the connecting portion 121, the fixing bracket 2 is arranged on the roof, the fixing bracket 2 is provided with a second fixing hole 21, the frame 12 is placed on the fixing bracket 2, and the first fixing hole 1211 and the second fixing hole 21 are aligned and overlapped, the self-locking component 3 sequentially passes through the first fixing hole 1211 and the second fixing hole 21 and forms a tightening force to fix the photovoltaic component 1 on the fixing bracket 2. The installation process between the components of the mechanism is simple. Since the self-locking component 3 is installed on the back of the frame 12, it avoids the situation where the frame 12 between adjacent photovoltaic components 1 must leave a position for the installation of the pressure block, so that there is no gap between adjacent photovoltaic components 1, which increases the installation space on the roof, and can install more photovoltaic components 1. In addition, there are no redundant components between the photovoltaic components 1, making the overall structure more concise and beautiful.

[0025] like Figure 1 and Figure 2 As shown, in one embodiment, the self-locking component 3 includes a lock core 31 and a lock sleeve 32. The lock sleeve 32 is sleeved on the lock core 31, and there is a gap between the lock core 31 and the lock sleeve 32. When the first fixing hole 1211 and the second fixing hole 21 are aligned, the head of the lock core 31 passes through the first fixing hole 1211 and the second fixing hole 21 in sequence and enters the lock sleeve 32, so that the lock core 31 and the lock sleeve 32 are fastened to achieve locking. It is simpler, more convenient and more efficient to fix the photovoltaic component 1 and the fixing bracket 2 by the lock core 31 and the lock sleeve 32. Optionally, the self-locking component 3 can also be a conventional lock on the market, but when selecting, it is necessary to meet or be able to lock the photovoltaic component 1 and the fixing bracket 2. Of course, in addition to selecting conventional locks, the self-locking component 3 can also be a bolt or a metal wire.

[0026] In one embodiment, a first limiting portion 311 is provided on the tail of the lock core 31, a transmission unit 4 is provided on the outer side wall of the tail of the lock sleeve 32, and a second limiting portion 40 is provided on the transmission unit 4. When the first limiting portion 311 and the second limiting portion 40 are buckled, the lock core 31 and the lock sleeve 32 are in a locked state and form an annular structure. The lock core 31 and the lock sleeve 32 are locked by the interaction between the first limiting portion 311 and the second limiting portion 40. Optionally, the first limiting portion 311 and the second limiting portion 40 are both serrated, and the direction of the serrations on the lock core 31 is opposite to that on the lock sleeve, and the serrations therebetween are the same in size. The first limiting portion 311 and the second protrusion restrict each other, so that the lock core 31 and the lock sleeve 32 can be locked. Optionally, the first limiting portion 311 may be a limiting groove, and the second limiting portion 40 may be a limiting buckle. When the limiting buckle is buckled into the limiting groove, the lock core 31 and the lock sleeve 32 are in a locked state. The first limiting portion 311 may also be a limiting ring, and the second limiting portion 40 may also be a limiting hook. When the limiting hook is hooked into the limiting ring, the lock core 31 and the lock sleeve 32 are in a locked state.

[0027] In one embodiment, the transmission unit 4 includes a transmission member 41, a support member 42 and an elastic element 43. The support member 42 is arranged on the outer side wall of the rear end of the lock sleeve 32. One end of the second limiting portion 40 close to the lock sleeve 32 is rotatably arranged on the support member 42. The transmission member 41 is rotatably arranged on the support member 42 and close to the head of the second limiting portion 40. One end of the elastic element 43 is connected to the back side of the second limiting portion 40 away from the lock core 31. The front side of the second limiting portion 40 has a limiting structure. The other end of the elastic element 43 is connected to the support member 42. When the transmission member 41 is separated from the head of the second limiting portion 40, it is buckled between the first limiting portion 311 and the second limiting portion 40 under the action of the elastic force of the elastic element.

[0028] It should be noted that the transmission member 41 is equivalent to the key of the lock core 31 and the lock sleeve 32. When the transmission member 41 rotates clockwise, the transmission member 41 will separate from the head against the second limiting portion 40. When separated, the elastic element 43 will generate an elastic force from the state of being compressed by the second limiting portion 40 to the state of being extended. Under the action of the elastic force, when the first limiting portion 311 and the second limiting portion 40 are buckled, the lock sleeve 32 and the lock core 31 will not separate, and the locked state is achieved. When the transmission member 41 rotates counterclockwise, until the transmission member 41 abuts against the second limiting portion 40, the elastic element 43 is compressed by the second limiting portion 40, and a gap is generated between the first limiting portion 311 and the second limiting portion 40, so that the lock sleeve 32 and the lock core 31 are separated, thereby achieving the unlocked state. Among them, although the transmission member 41 can rotate, it needs to be driven by a certain force to make it rotate. Under natural conditions, the transmission member 41 will not rotate, and the driving force of the transmission member 41 needs to be greater than the elastic force of the elastic element 43.

[0029] In one embodiment, the lock core 31 and the lock sleeve 32 are both in the shape of a half ring. Specifically, the lock core 31 and the lock sleeve 32 are concentric circles. When locked, an annular lock structure can be formed between the lock core 31 and the lock sleeve 32. In the unlocked state, a part of the lock core 31 is inside the lock sleeve 32, and another part of the lock core 31 is outside the lock sleeve 32.

[0030] In one embodiment, the gap between the lock core 31 and the lock sleeve 32 is 1 mm to 2 mm. The gap between the lock core 31 and the lock sleeve 32 allows the lock core 31 to extend out of the lock sleeve 32 when in a locked state, and to retract into the lock sleeve 32 when in an unlocked state.

[0031] In one embodiment, the opening diameter of the lock sleeve 32 is 3 mm to 5 mm. The cross-sectional diameter of the lock core 31 is 2 mm to 4 mm. Optionally, in order to adapt to the market environment, the opening diameter of the lock sleeve 32 can also be set to 2 to 10 mm, and the cross-sectional diameter of the lock core 31 can be 1 mm to 9 mm. Of course, the opening diameter of the lock sleeve 32 in this mechanism can be 4 mm, and the cross-sectional diameter of the lock core 31 can be 3 mm.

[0032] like Figure 3 As shown, in one embodiment, the connecting portion 121 is L-shaped. Optionally, the aperture of the first fixing hole 1211 of the connecting portion 121 is 6 mm-8 mm, and of course, the aperture of the second fixing hole 21 is also 6 mm-8 mm, wherein the width of the connecting portion 121 is 30 mm. Optionally, the length of the frame 12 is 1720 mm-2060 mm. The length of the connecting portion 121 is also 1720 mm-2060 mm, and four first fixing holes 1211 can be set on the bottom surface of the connecting portion 121, and any of the four first fixing holes 1211 can be used to cooperate with the second fixing hole 21. Optionally, there are four connecting portions 121 on the back side of a frame 12, and the four connecting portions 121 are all provided with a first fixing hole 1211. Of course, the number of the fixing bracket 2 will also be set corresponding to the frame 12, and the fixing bracket 2 is provided with a corresponding number of second fixing holes 21.

[0033] In summary, by replacing the current conventional roof component pressing block installation method with self-locking components, rapid and seamless installation between adjacent photovoltaic components on the roof can be achieved, saving installation costs and increasing the installed capacity of roof photovoltaic components.
