Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation equipment fixing brackets, in particular to photovoltaic power generation equipment fixing brackets. Background Art

[0002] Photovoltaic power generation equipment fixed support is a support structure that stably installs and fixes photovoltaic modules in a specific orientation and angle. It is mainly composed of columns, beams, diagonal beams and connectors, and is usually made of high-strength steel or aluminum alloy. Its most significant feature is that the angle and orientation remain unchanged after installation. The photovoltaic modules are often installed at the optimal angle based on factors such as the latitude of the installation site and the pattern of sunshine to maximize the reception of solar radiation. It is currently one of the most widely used types of support in the photovoltaic power generation field.

[0003] Patent application publication number CN220822951U discloses a fixed bracket for photovoltaic power generation equipment. The utility model includes a fixed bracket and a photovoltaic power generation equipment placed on the fixed bracket. The fixed bracket consists of a vertically arranged tripod and a crossbar connecting the tripod. The tripod includes a right-angle bracket I, a right-angle bracket II, and a connecting bracket. Right-angle bracket I is the hypotenuse of the tripod, and the photovoltaic power generation equipment is clamped between support blocks I and II. Right-angle bracket II is the bottom edge of the tripod, and a vertical downward bottom hook is provided at the intersection with right-angle bracket I. The bottom hook is fixed to a railing. The two ends of the connecting bracket are movably connected to right-angle bracket I and right-angle bracket II, respectively, to adjust the installation angle of the photovoltaic power generation equipment.

[0004] The above patent is equipped with a fixed bracket and a photovoltaic power generation equipment placed on the fixed bracket. However, the fixed inclination design of the photovoltaic bracket in the above patent relies on passive gravity drainage. The water holes of the mounting plate are easily blocked by dust and fallen leaves, resulting in water retention. Not only does long-term infiltration cause electrochemical corrosion and algae growth on the contact surface between the mounting plate and the photovoltaic panel, weakening the structural strength and reducing the power generation efficiency, but also in a low temperature and high humidity environment, static water is prone to freezing and expansion or continuous infiltration of the seals, accelerating the aging of the bracket. At the same time, manual cleaning of surface water on the panel requires frequent shutdowns, which significantly increases the operation and maintenance costs and safety risks, especially for rooftop and high-altitude power stations. The core problem is the lack of a dynamic drainage mechanism that can actively break the surface tension of accumulated water and impurity blockage, making it difficult to adapt to the long-term drainage needs in complex environments. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the present invention provides a photovoltaic power generation equipment fixing bracket to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a photovoltaic power generation equipment fixing bracket includes a base, a top of the base is fixedly connected to a swing mechanism, and a top of the swing mechanism is fixedly connected to a mounting plate;

[0007] The swing mechanism comprises:

[0008] A first bracket, wherein the bottom of the first bracket is fixedly connected to the outer wall of the base, and a motor drives the connecting rod to drive the round rod to rotate slightly forward and reverse in the plug-in hole, so that the threaded engagement between the threaded sleeve and the threaded barrel is converted into a periodic pitching swing of the mounting plate. This swing forces accumulated water to actively drip along the water-permeable hole, effectively reducing water accumulation on the surface of the photovoltaic panel, avoiding the limitations of traditional brackets that rely on gravity for passive drainage, and reducing corrosion and power generation efficiency loss caused by accumulated water;

[0009] a threaded barrel, the threaded barrel being fixedly connected to the outer wall of the first bracket;

[0010] A threaded sleeve, the threaded sleeve being threadedly connected to the threaded barrel, and the threaded sleeve being fixedly connected to the bottom of the mounting plate;

[0011] A power assembly is fixedly connected to the outer wall of the first bracket.

[0012] Preferably, the outer wall of the mounting plate is provided with a plurality of water holes for water permeation.

[0013] Preferably, the power assembly includes a motor, which is fixedly connected to the inner wall of the first bracket. The outer wall of the motor is fixedly connected to one end of a connecting rod via a rotating shaft, and the other end of the connecting rod is fixedly connected to a round rod.

[0014] Preferably, a plug hole is provided on the outer wall of the threaded sleeve, and the round rod is plugged into the plug hole. The intercepting plate is movably connected to the mounting plate through a movable rod, and is flexibly pulled to the second bracket by a spring. When the mounting plate swings, the spring is pulled or pressed to drive the intercepting plate to move slightly, so that the gap between the intercepting plate and the mounting plate changes dynamically, forming an intermittently expanded drainage channel, accelerating the drainage of accumulated water, and the spring cooperates with the second bearing to adaptively deflect to avoid jamming of the mechanism and improve reliability.

[0015] Preferably, the bottom of the mounting plate is movably connected with a receiving mechanism, and the handle rotates the limit plate to quickly clamp the photovoltaic panel, and the position is locked by using bolts to press the friction ring. It is easy to operate and firmly fixed. For strong wind environments, the photovoltaic panel and the mounting plate can be directly reinforced with screws, taking into account both conventional installation and extreme working conditions, and improving the environmental adaptability of the bracket.

[0016] Preferably, a hole is provided at the bottom of the mounting plate, and the receiving mechanism includes a movable rod, which is inserted into the hole of the mounting plate. One end of the movable rod is fixedly connected to an intercepting plate, and the intercepting plate is used to intercept the power generation plate.

[0017] Preferably, the other end of the movable rod is fixedly connected to the second bracket, the outer wall of the first bracket is rotatably connected to one end of a spring, and the other end of the spring is fixedly connected to the second bracket.

[0018] Preferably, the first support and the spring are rotationally connected through a second bearing, and the second bearing is arranged to adapt to a small degree of skew when the spring is stretched.

[0019] Preferably, the top of the mounting plate is fixedly connected with a limiting mechanism.

[0020] Preferably, the limiting mechanism comprises a first bearing fixedly connected to the top of the mounting plate, a handle rotationally connected to the outer wall of the first bearing, a limiting plate fixedly connected to the outer wall of the handle, a friction ring fixedly connected to the outer wall of the handle, a threaded seat fixedly connected to the top of the mounting plate, a bolt threadedly connected to the outer wall of the threaded seat, and the bolt is in movable contact with the friction ring.

[0021] The present application provides a photovoltaic power generation equipment fixing support. It has the following advantages:

[0022] 1. The photovoltaic power generation equipment fixing support drives the round rod in the plug-in hole to rotate forward and backward in a small range through the motor drive connecting rod, so that the threaded cooperation between the threaded sleeve and the threaded cylinder is converted into the periodic pitching swing of the mounting plate. The swing forces the accumulated water to actively drip along the water-permeable hole, effectively reducing the water accumulation on the surface of the photovoltaic panel, avoiding the limitations of traditional supports relying on passive drainage by gravity, and reducing corrosion and power generation efficiency loss caused by water accumulation.

[0023] 2. The photovoltaic power generation equipment fixing support is movably connected with the mounting plate through the intercepting plate and the movable rod, and is flexibly pulled to the second support by the spring. When the mounting plate swings, the spring is pulled or pressed to drive the intercepting plate to move slightly, so that the gap between the intercepting plate and the mounting plate changes dynamically, forming an intermittent and expanding drainage channel to accelerate the drainage of accumulated water. The spring cooperates with the second bearing to adapt to the skew, avoiding the mechanism from being stuck, and improving the reliability.

[0024] 3. The photovoltaic power generation equipment fixing support quickly clamps the photovoltaic panel by rotating the limiting plate with the handle, and locks the position by pressing the friction ring with the bolt, which is convenient to operate and firmly fixed. For strong wind environment, the photovoltaic panel and the mounting plate can be directly reinforced with screws, taking into account the conventional installation and extreme working condition requirements, and improving the environmental adaptability of the support.

[0025] 4. The photovoltaic power generation equipment fixing support naturally limits the lateral displacement of the mounting plate while achieving swing through the threaded cooperation between the threaded sleeve and the threaded cylinder, avoiding the threaded sleeve from coming out when the power assembly is driven. The plug-in design of the round rod and the plug-in hole further restricts the swing trajectory, forming a double protection of "threaded anti-dropping + plug-in limiting", ensuring the structural durability under high-frequency swing.

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but are not to be construed as limiting the present invention.

[0042] The power assembly 44 is fixedly connected to the outer wall of the first bracket 41 .

[0043] The outer wall of the mounting plate 2 is provided with a plurality of water holes 3 for water penetration;

[0044] The base 1 is set at the required position, and the photovoltaic power generation equipment is placed on the mounting plate 2. The water permeable hole 3 is opened on the mounting plate 2 to reduce water accumulation on the mounting plate 2. The threaded cylinder 42 is fixed to the base 1 through the first bracket 41. The mounting plate 2 is threadedly connected to the threaded cylinder 42 through the threaded sleeve 43. The motor 441 is connected to the connecting rod 442 through its own rotating shaft. The round rod 443 is inserted into the plug hole 444, thereby limiting the angle of the mounting plate 2. A fixed control degree is pre-set in the motor 441, which drives the round rod 443 to rotate five degrees clockwise and then five degrees counterclockwise. The reciprocating rotation drives the mounting plate 2 to swing slightly. The swing of the mounting plate 2 will slightly change the angle, thereby guiding the water on it to drip. In addition, the threaded connection between the threaded sleeve 43 and the threaded cylinder 42 will limit the lateral movement of the mounting plate 2, preventing the threaded sleeve 43 from falling off the threaded cylinder 42. The threaded connection between the two will drive a small lateral movement of the mounting plate 2, thereby changing the position of the mounting plate 2 and guiding the accumulated water to fall.

[0045] The power assembly 44 includes a motor 441 , which is fixedly connected to the inner wall of the first bracket 41 . The outer wall of the motor 441 is fixedly connected to one end of a connecting rod 442 via a rotating shaft, and the other end of the connecting rod 442 is fixedly connected to a round rod 443 .

[0046] An inserting hole 444 is formed on the outer wall of the threaded sleeve 43 , and the round rod 443 is inserted into the inserting hole 444 .

[0047] The motor 441 is connected to the connecting rod 442 through its own rotating shaft, and the round rod 443 is inserted into the plug hole 444, thereby limiting the angle of the mounting plate 2. A fixed control degree is pre-set in the motor 441, which drives the round rod 443 to rotate five degrees clockwise, and then five degrees counterclockwise. The reciprocating rotation drives the mounting plate 2 to swing slightly. The swing of the mounting plate 2 will slightly change the angle, thereby guiding the water on it to drip, and the threaded connection between the threaded sleeve 43 and the threaded barrel 42 will limit the lateral movement of the mounting plate 2, preventing the threaded sleeve 43 from falling off the threaded barrel 42. The threaded connection between the two will drive a small lateral movement of the mounting plate 2, thereby changing the position of the mounting plate 2 to guide the accumulated water to fall.

When the photovoltaic panel is installed, it is directly placed on the mounting plate 2, and then the intercepting plate 61 is intercepted at the bottom position. When the mounting plate 2 swings slightly, the second bracket 63 will be pulled by the spring 64, thereby driving the intercepting plate 61 to move slightly.
