Description

Technical Field

[0001] The present invention relates to the application field of photovoltaic products, and in particular to a balcony photovoltaic device and a photovoltaic system comprising the same. Background Art

[0002] In recent years, with the rapid development of the photovoltaic industry, my country's large-scale ground photovoltaic power stations, industrial and commercial distributed photovoltaic power stations, and household photovoltaic systems have been developed on a large scale. Of course, in recent years, due to the limitations of sites and power grids, photovoltaic development has also encountered some problems.

[0003] Therefore, in the application field of photovoltaic products, there is an urgent need to develop other application scenarios to further expand the photovoltaic market.

[0004] For example, currently, the balcony of residential houses has not been taken seriously due to its small area, difficulty in installation, high cost, and poor overall aesthetics. However, due to the large number of residential balconies, this field has a broad market size.

[0005] With the innovative development of photovoltaic technology in my country, the cost of photovoltaic systems has been greatly reduced, and balcony photovoltaic products have shown high economic efficiency. This field urgently needs to develop an application product that can solve the problems of combining photovoltaics with balconies, so that photovoltaics and building balconies can be perfectly combined.

[0006] Currently, if Figures 1 to 6 As shown in the figure, for the photovoltaic device on the balcony of the building, the photovoltaic components of the overall structure adopt a slide rail combined with a supporting structure, which is driven by a motor so that the inclination of the photovoltaic components can be automatically adjusted. The component installation adopts a plug-in and hanging method, which is convenient and fast.

[0007] However, there are still many problems in the trial installation process:

[0008] 1. The prior art adopts a combination of component support and slide rail structure, and the balcony component includes a photovoltaic component with a side groove, a hook 50, a support rod 10 and a slide rail 40 assembly. A connecting rod 60 is provided on the support rod 10, and a slider 70 is connected to the end of the connecting rod 60 and the end of the support rod for connecting with the slide rail 40.

[0009] The slide rail 40 is connected to the assembly by providing a step bolt 20 at the end 11 of the support rod 10, and connected to the slot nut 31 in the side groove of the frame 30 of the balcony assembly. However, the balcony assembly and the slide rail 40 are not fixed by only relying on this one bolt hinge connection. When the balcony assembly is plugged in (for example, using a hook 50), the assembly of the support rod 10 and the slide rail 40 and the balcony assembly are movable, and the plug-in installation process is not very convenient.

[0010] 2. When the motor retracts the balcony assembly, although there is a limit block in the slide rail, the balcony assembly is prone to slight shaking due to the inertial impact force when the starting motor stops.

[0050] To make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given in conjunction with the accompanying drawings.

[0051] Now, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Now, preferred embodiments of the present invention will be described in detail, and examples thereof are shown in the accompanying drawings. Whenever possible, the same reference numerals will be used throughout the drawings to represent the same or similar parts.

[0052] In addition, although the terms used in the present invention are selected from well-known and commonly used terms, some of the terms mentioned in the specification of the present invention may be selected by the applicant according to his or her judgment, and their detailed meanings are described in the relevant parts of the description herein.

[0053] In addition, it is required to understand the present invention not only through the actual terms used, but also through the meaning implied by each term.

[0054] As Figures 7 to 11 shown, the present invention discloses a balcony photovoltaic device, which includes a balcony assembly 100, at least two slide rails 200 and at least two support rods 300. The slide rails 200 are respectively installed on both sides of the balcony assembly 100, and the support rods 300 are respectively connected to the corresponding slide rails 200. Among them, one end of the slide rail 200 is fixedly connected to the side frame of the balcony assembly 100 through at least one upper limit rod assembly 400, and the other end of the slide rail 200 is fixedly connected to the side frame of the balcony assembly 100 through at least one lower side limit block assembly 500.

[0055] Furthermore, the slide rail 200 and the side frame of the balcony assembly 100 are fixed by at least one intermediate connecting bolt assembly 600 .

[0056] In view of the fact that the slide rail support assembly and the balcony assembly are not fixed in the prior art, in order to make the slide rail immobile during the installation process, the connection points between the slide rail and the assembly are increased. The technical solution of the present application adds an upper limit rod assembly 400 and at least two fixed connections of the middle connecting bolt assembly 600 between the side frames of the slide rail and the balcony assembly. In addition, a lower limit block assembly 500 can also be provided to perform lower positioning of the balcony assembly 100 and the slide rail 200. Combined with the connection between the original support and the balcony assembly, the movement of the slide rail support assembly and the assembly during installation can be effectively solved. Among them, the upper limit rod assembly 400 and the middle connecting bolt assembly 600 are removed after installation, mainly as auxiliary installation parts.

[0057] like Fig.12 and Fig.13 As shown, in this embodiment, the upper limit rod assembly 400 may include an upper limit screw 410 with a step 411 and a first slot nut 420. The first slot nut 420 is installed in the side frame of the balcony assembly 100, and the upper limit screw 410 passes through the slide rail 200 and is fixedly connected to the first slot nut 420.

[0058] For example, an open slot 210 is provided at the upper end of the slide rail 200, and the upper limit screw 410 is inserted into the open slot 210, and the slide rail 200 is clamped by the step 411 and the outer fastener 430. The setting of the open slot 210 facilitates the clamping of the upper limit screw 410.

[0059] The side frame 110 of the balcony assembly 100 is provided with a frame groove 111, the first slot nut 420 is clamped and installed in the frame groove 111, and the upper limit screw 410 is fastened and connected with the first slot nut 420. Here, the outer fastener 430 can be preferably an outer nut.

[0060] like Fig.14 As shown, the installation process of the upper limit screw assembly 400 is as follows: first, the first slot nut 420 on the upper limit screw 410 is inserted into the side slot of the frame of the balcony assembly 100, the upper limit screw 410 is moved downward and inserted into the upper end opening slot 210 of the slide rail 200, and the limit bolt is tightened so that the limit bolt is fixed in the frame slot of the balcony assembly 100. Then, the outer nut 430 is tightened to fix the slide rail 200 on the upper limit screw 410. When the upper limit screw assembly is plugged in, the nut and the screw are loosened, and the upper limit screw 410 is moved upward and taken out.

[0061] like Fig.15 and Fig.16As shown, in this embodiment, the lower limit block assembly 500 includes a clamping head seat 510 fixed to the slide rail 200, a clamping head 520 positioned with the side groove of the frame of the balcony assembly 100, a step bolt 530 and an elastic component 540 (for example, the elastic component 540 can be preferably a compression spring). The clamping head seat 510 is installed in the inner groove of the slide rail 200, and the step bolt 530 passes through the inner groove of the slide rail 200 and is installed in the clamping head seat 510. The elastic component 540 is installed between the clamping head seat 510 and the step bolt 530. One end of the clamping head 520 is fixed to the side frame of the balcony assembly 100, and the other end is installed in the clamping head seat 510, and is pressed against the step bolt 530.

[0062] Preferably, a convex strip 511 is respectively provided on the upper and lower outer wall surfaces of the clamping head seat 510 , and the clamping head seat 510 is clamped with the inner groove of the slide rail 200 through the convex strip 511 and fixed to the lower side of the slide rail 200 .

[0063] In this embodiment, Fig.17 As shown, preferably, the chuck seat 510 has a through hole 512 (for example, it can be set as a chuck guide square hole), and the elastic component 540 is installed in the through hole 512 and sleeved on the step bolt 530.

[0064] like Fig.18 As shown, one end of the clamp head 520 is provided with a connection portion 521 protruding outward, and the end of the connection portion 521 is preferably provided with an inclined surface, which matches the end surface of the side groove of the frame of the balcony assembly 100. The clamp head 520 is clamped in the side frame of the balcony assembly 100 through the connection portion 521. A threaded hole 522 is provided on the outer end surface of the connection portion 521 for connecting the step bolt 530.

[0065] The other end of the clamp 520 is a clamp body, which is inserted into the through hole 512. The wall surface of the clamp body clamped in the through hole 512 is a clamp guide surface 513, and there is a clearance fit between the clamp guide surface 513 and the through hole 512.

[0066] The step bolt 530 passes through the upper side hole of the slide rail and the compression spring in the guide square hole of the clamp head (i.e., the through hole 512), is aligned with the threaded hole 522 on the clamp head 520 and tightened until the step surface of the step bolt 530 is tightly combined with the bottom surface of the clamp head 520.

[0067] The clamping head 520 is retractable under the action of the compression spring (i.e., the elastic component 540). When the balcony assembly 100 is in a vertical state, the clamping head 520 clamps the side notch of the frame to limit the balcony assembly 100. When the assembly rotates, it can be easily disengaged by using the notch of the frame and the inclined surface of the clamping head 520. When the motor drives to open and retract the balcony assembly 100, the inclined surface of the notch of the side of the frame pushes the clamping head 520 to contact the inclined surface, and the clamping head 520 is retracted by the compression spring, so that the balcony assembly 100 and the clamping head 520 are disengaged and engaged.

[0068] like Fig.19 As shown, the assembly process of the lower limit block assembly 500 is as follows: first, the clamping head seat 510 is clamped into the inner groove of the slide rail 200, and the compression spring (i.e., the elastic component 540) and the clamping head 520 are placed in the through hole 512. Then, the step bolt 530 passes through the upper hole of the slide rail 200 and the compression spring (i.e., the elastic component 540) in the clamping head guide square hole (i.e., the through hole 512), aligns with the threaded hole 522 on the clamping head 520, and is tightened until the step surface is tightly fitted with the bottom surface of the clamping head.

[0069] like Fig. 20 and Fig.21 As shown, in this embodiment, preferably, the middle connecting bolt assembly 600 includes a middle connecting bolt 610 and a second slot nut 620. An open slot 210 is provided on the slide rail 200, the middle connecting bolt 610 is passed through the open slot 210, the second slot nut 620 is installed in the side frame of the balcony assembly 100, and the middle connecting bolt 610 is connected to the second slot nut 620.

[0070] In addition, further, a cushion block 700 is provided between the slide rail 200 and the side frame of the balcony assembly 100 , and the middle connecting bolt 610 passes through the cushion block 700 .

[0071] Specifically, the middle connecting bolt 610 passes through the upper hole of the slide rail 200 and is connected to the second slot nut 620 in the side slot of the frame of the balcony assembly 100. The second slot nut 620 is pre-installed in the frame slot (for example, the step bolt at the end of the strut and the motor seat bolt are combined to connect the second slot nut), and a cushion block 700 can also be set between the slide rail 200 and the frame of the balcony assembly 100. When the balcony assembly 100 is installed, the middle connecting bolt 610 is loosened and taken out.

[0072] The present invention also provides a photovoltaic system for combining photovoltaics with building balconies, which comprises the balcony photovoltaic device as described above.

[0073] In summary, the balcony photovoltaic device and the photovoltaic system including the same of the present invention increase the connection points between the slide rail and the component to make the slide rail inactive, and position the component and the slide rail at the bottom. This structural improvement makes the structure of the balcony photovoltaic device more perfect, the plugging and hanging process of the balcony component is more convenient, and the bottom of the balcony in a static state is better limited.
