Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic brackets and relates to a movable liftable photovoltaic bracket. Background Art

[0002] Photovoltaic power generation is a process that converts solar photons into electricity through the photovoltaic effect in semiconductor materials. In recent years, the country has increasingly prioritized photovoltaic power generation, assuming a crucial position in the nation's energy strategy. Photovoltaic mounting brackets, the backbone of photovoltaic panels, are essential components. However, the practical operation of photovoltaic power generation presents several pressing challenges.

[0003] First, dust, dirt, and other contaminants easily accumulate on the surface of photovoltaic panels. This contaminant blocks sunlight, reducing the panels' efficiency in receiving solar energy, which directly impacts power generation efficiency. To overcome this problem, regular panel cleaning is essential. Cleaning removes surface contaminants, improves panel efficiency, and extends their lifespan.

[0004] Secondly, photovoltaic panels are at risk of damage over long-term use, necessitating regular maintenance to ensure proper operation. However, most current photovoltaic power plants utilize fixed photovoltaic mounting brackets, which presents challenges for robots performing cleaning and maintenance operations. Because the brackets are fixed, there's a risk of robots colliding with them during operation, potentially damaging the robot and even disrupting the operation of the entire power generation system.

[0005] Furthermore, existing methods for adjusting the angle of photovoltaic mounts also have drawbacks. Typically, the angle is adjusted by using the height difference of the legs. However, this method is not only time-consuming and labor-intensive, but also lacks high adjustment accuracy. In practical applications, this method struggles to precisely adjust the angle of the photovoltaic panels, thus impacting the efficiency and stability of photovoltaic power generation.

[0006] Therefore, it is necessary to improve the existing technology to overcome the defects in the existing technology. Utility Model Content

[0007] The purpose of the present utility model is to provide a movable liftable photovoltaic support, which solves at least one problem in the background technology through structural improvement.

[0008] The purpose of this utility model is achieved through the following technical solutions:

[0009] A mobile, liftable photovoltaic support comprises a mobile support and a crossbeam, wherein the mobile support is provided with a vertical lifting assembly, the upper end of the vertical lifting assembly is pivotally connected to the crossbeam, at least two support members are detachably provided on the crossbeam, and solar panels are detachably provided on two adjacent support members; an auxiliary support is provided on one side of the crossbeam, the auxiliary support is hinged to one end of an inclined jack, and the other end of the jack is hinged to the mobile support or the vertical lifting assembly.

[0035] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0036] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0037] In the present invention, unless otherwise specified, directional words such as "up, down, top, bottom" are usually used with reference to the directions shown in the drawings, or with reference to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention. Example

[0038] See also Figure 1-Figure 3 As shown, a mobile, liftable photovoltaic support comprises a mobile support 1 and a crossbeam 2. A vertical lift assembly 3 is provided on the mobile support 1, and the upper end of the vertical lift assembly 3 is pivotally connected to the crossbeam 2. This connection design not only ensures structural flexibility but also facilitates subsequent adjustment operations.

[0039] At least two removable supports 4 are mounted on the crossbeam 2. These supports 4 provide a stable mounting base for the solar panels 5, and their removable nature makes installation and maintenance more convenient and efficient. Two adjacent supports 4 are also removably mounted with solar panels 5, making replacement or repair of the solar panels quick and easy.

[0040] An auxiliary bracket 6 is provided on one side of the crossbeam 2. The auxiliary bracket 6 is hingedly connected to one end of an obliquely arranged jack 7. The other end of the jack 7 is hingedly connected to the vertical lift assembly 3 (of course, the other end of the jack 7 can also be hinged to the mobile bracket 1). In this embodiment, an auxiliary bracket is also provided on the vertical lift assembly 3 for hinged connection of one end of the jack 7.

[0041] During use, the screw on the jack 7 is rotated to control the rotation of the crossbeam 2, thereby adjusting the tilt angle of the photovoltaic rack. The jack 7 is connected by a pivot pin, which is positioned with a cotter pin. To dismantle the jack 7, simply remove the cotter pin, pull out the cotter pin, and immediately remove the jack 7, making it easy to operate.

[0042] Specifically, the vertical lifting assembly 3 includes a screw lift 32 driven by a handle 31 , and a support beam 33 is provided on the screw lift 32 .

[0043] A first rotating shaft seat 81 is provided at the upper end of the support beam 33, and correspondingly, a second rotating shaft seat 82 is provided at the lower end of the crossbeam 2. The first rotating shaft seat 81 and the second rotating shaft seat 82 are connected by a pivot, and a shaft pin 83 is cleverly used to achieve a stable connection. In order to further ensure the stability and reliability of the connection, a retaining ring 84 is provided on the above-mentioned shaft pin 83, and the retaining ring 84 is precisely placed on the side of the second rotating shaft seat 82. In addition, a cotter pin 85 is also provided on the shaft pin 83 outside the retaining ring 84. This multiple protection design effectively prevents the shaft pin 83 from accidentally falling off during operation, thereby ensuring the safety and stability of the entire structure.

[0044] It's worth noting that on-site personnel can easily adjust the height of the crossbeam 2, and thus the height of the photovoltaic rack, by simply turning the handle 31. This manual adjustment method has significant advantages. For example, in locations with unstable power supply or where automated equipment cannot be relied upon, manual operation can still ensure smooth height adjustment. It also avoids the risk of collision between the robot and the photovoltaic rack.

[0045] In this embodiment, the crossbeam 2, the solar panel 5, the auxiliary bracket 6 and the second shaft seat 82 thereon together form an integral photovoltaic unit. When the photovoltaic unit is removed as a whole, only the corresponding cotter pins need to be removed and the corresponding shaft pins can be pulled out, which is easy to operate.

[0046] This integrated photovoltaic unit design offers significant advantages. If a photovoltaic unit becomes damaged, the entire unit can be replaced without having to inspect and repair each component individually. This design significantly speeds up repairs, saving both time and costs.

[0047] For example, if a photovoltaic unit in a large-scale photovoltaic power plant is accidentally damaged, it may take maintenance personnel a long time to detect and identify the specific faulty component. Now, by replacing the entire unit, the normal operation of the power generation system can be quickly restored.

[0048] Furthermore, this complete replacement approach significantly improves the working environment for maintenance personnel. They no longer need to perform lengthy, tedious repairs at complex on-site locations. Damaged components can be repaired indoors, reducing their exposure to harsh environments, lowering workload and risks, speeding up repairs, and improving their working environment.

[0049] In this embodiment, the mobile bracket 1 includes a bottom beam 11, and a vertical beam 12 is vertically arranged on the upper part of the bottom beam 11 to play a stable supporting role. The limiting sleeve 13 is precisely arranged on the vertical beam 12 and plays an important limiting function.

[0050] The bottom of the bottom beam 11 is provided with heavy-duty casters 14, which enables the entire mobile bracket to move flexibly and adapt to different installation locations and environmental requirements.

[0051] A screw lift 32 is provided between the bottom beam 11 and the support beam 33. The support beam 33 passes vertically through and is arranged in the limiting sleeve 13, and the support beam 33 can move up and down smoothly in the limiting sleeve 13.

[0052] By manually rotating the handle 31 , the movement of the screw of the screw lift 32 can be easily adjusted, thereby driving the support beam 33 to move accordingly, and finally achieving the lifting operation of the solar panel 5 .

[0053] For example, when cleaning or inspecting solar panels, the panels can be raised by turning a handle. This allows the robot to pass easily underneath, effectively preventing collisions. This design not only facilitates routine maintenance but also improves efficiency and safety. Whether in large-scale photovoltaic power plants or complex installation environments, this mobile and retractable stand demonstrates excellent adaptability and practicality.

[0054] In this embodiment, two shoulder screws 9 are provided on the support beam 33. These effectively limit the lifting travel of the solar panel. Without proper limiting measures, excessive rotation during the solar panel lifting process could cause the screw to dislodge, potentially leading to serious safety hazards and equipment failure.

[0055] Shoulder screw 9 limits the range of the solar panel's lift. For example, if an operation error or abnormality occurs during operation, the shoulder screw can immediately prevent excessive lift, ensuring that the screw rod is always in a safe and stable working state, safeguarding the normal operation of the entire photovoltaic power generation system and the integrity of the equipment.

[0056] In this embodiment, the photovoltaic bracket utilizes a sturdy and durable steel structure. The support member 4 is constructed of channel steel and features two extending support sections. This unique design allows for a secure, bolted connection between the support section and the solar panel 5. The crossbeam 2 utilizes H-shaped steel, enhancing the overall structural strength.

[0057] A limiting member is provided under the crossbeam 2, which is also made of channel steel. Bolt assemblies are also provided on both sides of the crossbeam 2 to tightly fix the support member 4 and the limiting member together.

[0058] The bolt-locked connection method allows for flexible adjustment of the position of the support member 4 on the beam 2. For example, when solar panels 5 of different sizes or specifications need to be placed, the position of the support member 4 can be easily adjusted to achieve optimal support and fixation effects, meeting diverse usage requirements.

[0059] This embodiment of the photovoltaic bracket demonstrates excellent performance and convenient operation in terms of angle adjustment. The photovoltaic unit at the top is considered as a whole, and the key to angle adjustment is to rotate the screw on the jack. Through the linear telescopic movement of the jack, the solar panel can be cleverly rotated.

[0060] It's worth noting that the jack 7 has a stroke of 245mm and is carefully designed to allow for adjustment within a 42° angle between the solar panel 5 and the support beam 33. In other words, every 1mm adjustment of the jack translates to approximately 1.1° of rotation. This precise adjustment mechanism allows for fine-tuning of the solar panel angle.

[0061] In actual operation, the entire process is simple and convenient, saving time and effort, and can be easily completed by just one person. For example, at different times of the day, the operator can easily adjust the angle of the solar panel according to the changes in the sun's position by fine-tuning the jack, so that it is as right angle as possible to the sunlight angle. Compared with traditional and complex angle adjustment methods, this design that can achieve angle fine-tuning with only a jack greatly reduces the difficulty of operation and labor costs. This makes it easier to achieve the ideal sunlight angle, significantly improving the photovoltaic conversion efficiency of the solar panel and bringing higher benefits to photovoltaic power generation.
