[0002] The photovoltaic mounting system is one of the key pieces of equipment for constructing a photovoltaic power plant; photovoltaic mounting systems are divided into fixed and tracking systems, depending on whether or not they follow the sun's movement. Fixed mounting systems can be further classified into ordinary fixed and adjustable fixed mounting systems. While tracking systems can increase electricity production, they require power supply devices, which reduces their stability and increases operating costs; ordinary fixed mounting systems have a simple structure and are affordable, but their electricity production efficiency is low. Adjustable fixed mounting systems allow the angle to be adjusted according to the months or seasons, thus increasing electricity production.However, with current adjustable fixed brackets, it is necessary to loosen the fixing bolts, adjust the angle of inclination of the bracket according to experience, and then tighten the bolts again, which makes the operation complicated.

SPECIFIC IMPLEMENTATION METHODS

[0027] In order to make the objectives, technical solutions and advantages of the present invention clearer, detailed descriptions are provided below in conjunction with the figures.

[0028] It is important to note that all references to "first" and "second" in the examples of implementation of the present invention are intended solely to distinguish between two similar entities or parameters and should not be considered limiting. These distinctions will not be repeated in subsequent examples.

[0029] Terms of direction and position, such as "up", "down", "front", "back", "left", "right", "inside", "outside", "top", "bottom", "side", etc., are used with reference to the direction or position of the figures. They serve only to explain and understand the present invention and shall not be interpreted as limiting.

[0030] An adjustable mounting bracket for a photovoltaic panel, as illustrated in [Fig. 1], comprises a pair of fixed rods 1 of non-adjustable length and a pair 2. Two fixed rods 1 are arranged parallel to each other, and a first connecting bar 3 is securely fixed between them. The two telescopic rods 2 are also arranged parallel to each other, with a second connecting bar 4 fixed between them. One end of the fixed rods 1 is hinged to a first lower mounting plate 5, while the other end is hinged to one end of the telescopic rods 2. The other end of the telescopic rods 2 is hinged to a second lower mounting plate 6. This arrangement forms a triangular support between the fixed rods 1 and the telescopic rods 2. By adjusting the length of the telescopic rods 2, the angle of the fixed rods 1 can be changed, thus changing the tilt angle of the photovoltaic panel fixed to the fixed rods 1.

[0031] The telescopic rods 2 comprise an internal element 201 and an external element 202, connected in a sliding manner and having a locking structure, allowing at least two extendable locking heights to be obtained between said internal element 201 and said external element 202.

[0032] More precisely, as illustrated in [Fig. 2], the internal element 201 is provided with at least two first locking holes 203 distributed along the axis. As illustrated in [Fig. 3], the external element 202 has a corresponding second locking hole 204.

[0033] As illustrated in [Fig. 4], the two ends of the second connecting bar 4 are securely fixed to the external elements 202. As illustrated in [Fig. 5], the locking structure is located on the second connecting bar 4. More specifically, as illustrated in [Fig. 6] and [Fig. 7], the locking structure comprises a movable pin 7, a pressure element 8, and a control device 9. A hollow channel 401 is provided inside the second connecting bar 4, corresponding to the second locking hole 204. Said movable pin 7 can slide inside the hollow channel 401 and has a locked position, where it inserts into the first locking hole 203 and the second locking hole 204 to maintain the telescopic height, and an unlocked position, where it exits the first locking holes 203, thus allowing the adjustment of the telescopic rods.The pressure element 8 acts on the movable pin 7 to maintain the locked position, and the control device 9 is used to move the movable pin 7 from the locked position to the unlocked position.

[0034] As shown in [Fig. 6] and [Fig. 7], the central part of the second connecting bar 4 has a mounting groove 402, and a limiting block 403 is securely fixed inside this mounting groove 402. Each end of the limiting block 403 is equipped with a movable pin 7, each movable pin 7 being designed to match one of the telescopic rods 2. The pressure element 8 is a compression spring located between the limiting block 403 and each movable pin 7.

[0035] More specifically, each side of the limiting block 403 has a limiting groove for springs 404, and the pressure element 8 is installed inside these limiting grooves for springs 404.

[0036] More specifically, the control device 9 is a pressure lever movably mounted on the second connecting bar 4. The movable pin 7 is equipped with an inclined drive surface 701, which cooperates with the control device 9 to form a linkage mechanism. By pressing the control device 9, the two movable pins 7 move simultaneously from the locked position to the unlocked position.

[0037] More specifically, the movable pin 7 is securely connected to a drive block 702, and the inclined drive surface 701 is located on this drive block. The control device 9 has a cooperation groove 901 for inserting the drive block 702, and the outer edge of this cooperation groove 901 forms a contact area 902 with the inclined drive surface 701.

[0038] More specifically, said control device 9 also includes a first limiting groove 903 adapted to the shape of the limiting block 403, the latter being inserted into the first limiting groove 903 to allow only linear movement of the control device 9.

[0039] The drive block 702 is fixed to the movable pin 7 by a threaded connection, and the movable pin 7 protrudes from the drive block 702. Said pressure element 8 surrounds the protruding part of the movable pin 7 relative to the drive block 702, and bears at its end against the drive block 702.

[0040] More specifically, as illustrated in [Fig. 8], the second connecting bar 4 is a profile, consisting of a central tube 407 and a connecting frame 405 fixed around the periphery of the central tube 407. The connecting frame 405 has a connecting rail groove, and the edges of this groove of the connecting frame 405 form a guide rail 406. The internal cavity of the central tube 407 forms the hollow channel 401, and the mounting groove 402 is located in the center of the central tube 407. The limiting block 403 is fixed to the inner wall of the central tube 407, either by one-piece molding or by welding, as in this embodiment.

[0041] The connecting frame 405 is equipped with a limiting element 10 fixed to the guide rail 406. The control device 9 has projecting stops 904 on each side, while the limiting element 10 is located at both ends of the control device 9 and includes a second limiting groove 1001 adapted to the projecting stops 904.

[0042] As illustrated in [Fig.9], the limiting element 10 comprises an upper base 1002 and a lower base 1003, separated by a certain space. A connecting bar 1004 is securely fixed on one side to connect the upper base 1002 and the lower base 1003. The second limiting groove 1001 is located on the upper base 1002, and both the upper base 1002 and the lower base 1003 are equipped with threaded clamping components 11. The guide rail 406 is situated between the upper base 1002 and the lower base 1003. Both the upper base 1002 and the lower base 1003 have a threaded clamping component 11, which allows for switching between a loose and a tight fit with the guide rail 406. Thanks to the threaded clamping component 11, the limiting element 10 can be removed even if the control device 9 is detachable.On site, the control device 9 and the limiting element 10 do not need to be installed on the fixed support; when it is necessary to adjust the angle of inclination, the adjustment operation is carried out by installing the control device 9 and the limiting element 10. For several fixed supports, a set of the control device 9 and the limiting element 10 can be shared.

[0043] As illustrated in [Fig.1], the control device 9 of this example embodiment is positioned under the second connecting bar 4, which corresponds better to ergonomic principles, thus facilitating the application of force.

[0044] The above disclosure is merely a preferred embodiment of the present invention. It cannot, of course, be used to limit the scope of the present invention. Therefore, equivalent modifications to the present invention always fall within the scope of the present invention.
