Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to a wall-mounted photovoltaic bracket. Background Technology

[0002] A photovoltaic (PV) power station is a power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. It can operate independently or be connected to the grid. PV modules are typically mounted on an installation surface using brackets.

[0003] Traditional photovoltaic (PV) brackets are installed at a fixed angle to receive sunlight and utilize solar energy. For example, patent document CN107947697A discloses a PV bracket, which protects the following: "It includes a base support and a support frame set on the working surface. In the longitudinal direction, the base support has two rows, front and back, with multiple base supports in each row; the longitudinal beams are inclined, with the front end of the longitudinal beam lower than the rear end; there is an angle between the plane where the support frame is located and the horizontal plane formed by the tops of the two rows of base supports; each base support in the rear row is hinged to an inclined support beam at its top; the front end of each longitudinal beam is hinged to one of the base supports in the front row, and the middle and rear part of each longitudinal beam is hinged to the upper end of an inclined support beam; in the transverse direction, the two outermost inclined support beams are respectively provided with cross-shaped back tie rods between them and their adjacent inclined support beams." The PV bracket structure of this invention is stable and the stress is reasonable and uniform. While meeting stability requirements, it greatly reduces the number of components and connection nodes, significantly reducing steel consumption, assembly time, and installation costs.

[0004] However, when the aforementioned photovoltaic brackets are fixed to the roof or other fixed objects, the angle of the photovoltaic brackets themselves cannot be adjusted according to the actual situation, so the angle of the photovoltaic modules cannot be adjusted, which is very inconvenient when using them. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is to overcome the problem that most photovoltaic brackets for installing photovoltaic modules in the prior art are fixed structures, so the tilt angle of the photovoltaic bracket cannot be adjusted during installation, resulting in relatively low power generation efficiency.

[0006] To solve the above-mentioned technical problems, this utility model provides a wall-mounted photovoltaic bracket, comprising: a mounting surface on which a fixed seat is provided; a supporting crossbar, one end of which is fixed to the mounting surface; a sliding rod connected to a sliding block slidably connected to the supporting crossbar, the sliding block being movable along the length direction of the supporting crossbar; a connecting sleeve hinged to the sliding rod; a push rod, one end of which extends into the connecting sleeve, and the depth of the push rod extending into the connecting sleeve being adjustable, the other end of the push rod being fixed by the fixed seat; a connecting rod, one end of which is hinged to the sliding block; an inclined beam, one end of which is hinged to the end of the supporting crossbar away from the mounting surface, and the inclined beam and the supporting crossbar are arranged in a "V" shape, the other end of the inclined beam being hinged to the end of the connecting rod away from the sliding block; and a mounting beam fixedly mounted on the inclined beam, the mounting beam being used to mount photovoltaic panels.

[0007] In one embodiment of this utility model, both the inner wall of the connecting sleeve and the fixing seat are provided with internal threaded holes.

[0008] In one embodiment of this utility model, the push rod is a cylindrical rod, and both ends of the push rod are provided with external threads. The push rod is connected to the internal threaded hole of the connecting sleeve and the fixed seat through the external threads.

[0009] In one embodiment of this utility model, a reinforcing strut is connected to the end of the supporting crossbar away from the mounting surface. The reinforcing strut and the supporting crossbar are arranged in a "V" shape, and the other end of the reinforcing strut is fixed to the mounting surface.

[0010] In one embodiment of this utility model, the supporting crossbar consists of two parallel rods, and each end of the sliding rod is provided with a sliding block, which is sleeved on the supporting crossbar.

[0011] In one embodiment of this utility model, the sliding block is a rectangular block, and a rectangular through hole is provided inside the sliding block. A roller is installed inside the rectangular through hole, and the roller is in rolling connection with the outer wall of the support crossbar.

[0012] In one embodiment of this utility model, a limiting block is provided on the supporting crossbar, which is used to limit the position of the sliding block. To prevent the short support from forming a right angle or acute angle with the inclined beam of the support, which would be detrimental to structural safety, a limiting block is provided at the middle position above the horizontal crossbar to limit the displacement range of the sliding box.

[0013] In one embodiment of this utility model, the inclined beams are two parallel beams, and the two inclined beams are arranged in a one-to-one correspondence with the two supporting crossbars.

[0014] In one embodiment of this utility model, the mounting beam consists of two parallel beams, and the mounting beams and the inclined beams are arranged in a "well" shape.

[0015] This utility model provides a photovoltaic module, including the aforementioned wall-mounted photovoltaic bracket and a photovoltaic panel installed on the photovoltaic bracket.

[0016] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial effects:

[0017] The wall-mounted photovoltaic bracket described in this utility model can extend the push rod by rotating it, making it convenient for operators to push the bracket on the roof or balcony. After rotating to the appropriate length, the push rod is fixed by the fixing seat. The push rod is hinged to the sliding block, and the push rod drives the sliding rod to move back and forth. With the connection between the connecting rod and the inclined beam, the tilt angle of the bracket can be changed. This photovoltaic bracket is wall-mounted and can be used on home balconies or flat roofs to meet household electricity needs. At the same time, the tilt angle can be adjusted according to the sunlight conditions. The method is simple and brings more power generation revenue. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0025] Reference Figure 1 , 2As shown, the wall-mounted photovoltaic bracket of this utility model includes: a mounting surface 100, a supporting crossbar 1, a sliding rod 2, a sliding block 3, a connecting sleeve 4, a push rod 5, a connecting rod 6, an inclined beam 7, and a mounting beam 8; the mounting surface 100 is provided with a fixed seat 101; the supporting crossbar 1 is fixed at one end to the mounting surface 100; the sliding rod 2 is connected to a sliding block 3 that is slidably connected to the supporting crossbar 1, and the sliding block 3 can move along the length direction of the supporting crossbar 1; the connecting sleeve 4 is hinged to the sliding rod 2; the push rod 5, its One end of the push rod 5 extends into the connecting sleeve 4, and the depth of the push rod 5 extending into the connecting sleeve 4 can be adjusted. The other end of the push rod 5 is fixed by the fixing seat 101. The connecting rod 6 has one end hinged to the sliding block 3. The inclined beam 7 has one end hinged to the end of the supporting crossbar 1 away from the mounting surface 100, and the inclined beam 7 and the supporting crossbar 1 are arranged in a "V" shape. The other end of the inclined beam 7 is hinged to the end of the connecting rod 6 away from the sliding block 3. The mounting beam 8 is fixedly installed on the inclined beam 7. The mounting beam 8 is used to install photovoltaic panels.

[0026] The connection structure between the connecting sleeve 4 and the push rod 5 is as follows: both the inner wall of the connecting sleeve 4 and the fixing seat 101 are provided with internal threaded holes. The push rod 5 is a cylindrical rod, and both ends of the push rod 5 are provided with external threads. The push rod 5 is connected to the internal threaded holes of the connecting sleeve 4 and the fixing seat 101 through the external threads. By adjusting the position of the push rod 5 screwed into the connecting sleeve 4, the sliding rod 2 can be placed in different positions of the supporting crossbar 1, thereby adjusting the angle between the inclined beam 7 and the supporting crossbar 1 through the connecting rod 6, achieving the purpose of adjusting the angle of the photovoltaic panel.

[0027] In the above structure, the supporting crossbars 1 are two parallel rods, and each end of the sliding rod 2 is provided with a sliding block 3, which is sleeved on the supporting crossbars 1. The inclined beams 7 are two parallel rods, and the two inclined beams 7 are arranged one-to-one with the two supporting crossbars 1.

A roller 32 is installed inside the rectangular through hole 31, and the roller 32 is in rolling connection with the outer wall of the supporting crossbar 1. Preferably, the rectangular through hole 31 contains upper and lower rollers 32, which not only confines the supporting crossbar 1 inside the sliding block 3, ensuring the vertical stability of the sliding block 3, but also allows the supporting crossbar 1 to roll back and forth without obstruction, driving the upper hinged connecting rod 6 to deflect.

[0029] Reference Figure 3As shown, a limiting block 11 is provided on the supporting crossbar 1, which is used to limit the position of the sliding block 3. By setting the limiting block 11, the sliding block 3 is limited from moving beyond the safe range, thus improving the safety of the overall support.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
