Background Art

[0002] With the surge in global demand for clean energy, desert regions with abundant sunlight and vast land have become ideal locations for large-scale photovoltaic power plants. However, desert environments are characterized by high wind speeds, frequent sandstorms, large temperature swings between day and night, and the accumulation of dust and sand. These harsh natural conditions pose significant challenges to the safe and stable operation of photovoltaic modules. Strong wind loads are one of the most significant and frequent threats.

[0003] In photovoltaic projects, fixed mounting systems are often arranged vertically in double rows. To ensure energy production and meet regulatory requirements, the panels are typically positioned 1.5 to 2.0 meters above the ground. Traditional standard photovoltaic mounting systems often perform poorly in extreme desert wind conditions (such as gusts, cyclones, and sustained gales). Windblown sand easily accumulates on the panel surfaces, tearing the panel frames. In severe cases, entire panels can be blown off and dislodged, potentially causing serious accidents.

[0004] This not only results in significant direct economic losses (including module damage, mounting repairs and replacements, and power generation losses), but also poses serious safety risks (flying modules could injure people or damage other equipment). Frequent maintenance also significantly increases power plant operating costs. Therefore, there is an urgent need to develop a photovoltaic module system that offers superior wind resistance and reliability in high-wind environments such as deserts, mountains, and wastelands, while also flexibly reducing module loads.

DETAILED DESCRIPTION

[0019] like Figures 1 to 6The present invention provides a composite adjustable mounting bracket system for photovoltaic power generation components suitable for safe operation in high-wind environments such as deserts, mountains, and wastelands. The composite adjustable mounting bracket system includes a mounting base, a guide support skeleton 1, and a fixed mounting frame 2. The guide support skeleton includes at least two layers of slideways 3. The number of fixed mounting frames equipped with photovoltaic panels 4 is equal to the number of slideways 3. Each fixed mounting frame 2 is movably arranged on the guide support skeleton 1 via a layer of slideways 1. The guide support skeleton 1 arranged on the mounting base is improved in its wind resistance by reducing the windward area during the partial or complete overlap of the fixed mounting frames 2 that can move along each layer of slideways 3. The technical solution provided by the present application is based on the existing mounting base, and constitutes the composite adjustable mounting bracket system of the present application by adding a guide support frame and a fixed mounting frame, and then at least two layers of slides are set on the guide support frame, and the number of fixed mounting frames with photovoltaic panels fixed thereon is set to be equivalent to the number of slide layers, and then each fixed mounting frame is arranged on the guide support frame through a layer of slides; in this way, after the composite adjustable mounting bracket system of the present application is used to arrange and install photovoltaic power generation components, no matter when gusts, tornadoes or continuous strong winds occur in severe weather such as deserts, mountains or wastelands, the guide support frame arranged on the mounting base can at least improve its wind resistance by reducing the windward area of ​​each fixed mounting frame moving along each layer of slides during partial or complete overlap, thereby achieving the purpose of reducing the detachment of photovoltaic panels caused by extreme strong winds, or even flying out to injure people and damage to the equipment itself, thereby making the photovoltaic panels arranged using the composite adjustable mounting bracket system provided by the present application suitable for safe operation in strong wind environments such as deserts, mountains and wastelands. Of course, as the fixed installation frame moves within the slideway, the dust accumulated on the photovoltaic panels can also fall off due to the movement of the photovoltaic panels, achieving a certain dust cleaning purpose. At this time, based on the actual situation of extreme wind conditions, combined with the structural characteristics of the installation chassis of this application including at least two rows of chassis steel pipes 5 and a set of connecting support trusses 6, the composite adjustable installation bracket system described in this application also includes a skeleton inclination adjustment component composed of hydraulic push rods, and the guide support skeleton 1 is supported on each row of chassis steel pipes 5 with an adjustable inclination angle through the connecting support trusses 6 in cooperation with the skeleton inclination adjustment component; in this way, the wind resistance of the guide support skeleton 1 can also be improved by reducing its angle with the wind direction through the skeleton inclination adjustment component in cooperation with the connecting support trusses 6.

[0020] Accordingly, in order to facilitate the monitoring of extreme wind conditions within the wind power station, and at the same time to maximize the automatic movement of the fixed installation frame 2 according to the wind conditions, and to fix the fixed installation frame 2 that has been moved into place to prevent it from sliding freely in the slide 3 with the wind, the composite adjustable installation bracket system described in the present application also includes a composite drive locking component and a monitoring and control component. The photovoltaic panels 4 are arranged at corresponding positions of the photovoltaic power station through the fixed installation frame 2 in cooperation with the guide support frame 1 and the installation base frame, and the extreme wind conditions within the photovoltaic power station are monitored by the monitoring and control component; each fixed installation frame 2 can move back and forth along the corresponding slide 3 on the guide support frame 1 under the control of the output information of the monitoring and control component through the composite drive locking component, and be locked at the corresponding position of the guide support frame 1 as required. In this case, the monitoring and control assembly includes a monitoring component group and a control component group. The monitoring component groups are respectively arranged at corresponding locations within the photovoltaic power generation station. The data lines of the monitoring component groups and the control end of the composite drive and locking assembly are respectively connected to the control component group. The fixed installation frame 2 is driven to slide or lock in the corresponding slideway 3 by the composite drive and locking assembly based on the extreme wind conditions detected by the monitoring component group, in cooperation with the control component group. The control component group includes at least one programmable module 8 and an information input and display mechanism. Prefabricated programs are input into the programmable module 8 via the information input and display mechanism. The control end of each set of hydraulic push rods, the data line of each set of anemometers 7, and the control end of the composite drive and locking assembly are respectively connected to the programmable module 8. Preferably, the monitoring component group includes multiple sets of anemometers 7. The data lines of each set of anemometers 7 arranged at specified locations within the photovoltaic power generation station are respectively connected to the control component group. Extreme wind speed and / or wind direction within the photovoltaic power generation station are respectively monitored by each set of anemometers 7. It should be noted that the prefabricated information input into the programmable module 8 of this application is pre-set by the programmable module supplier according to customer requirements. Of course, during subsequent use, the customer can also re-edit the usage program of the programmable module to expand the scope of use.

[0021] Furthermore, as another important component improved in the present application, in order to achieve stable sliding operation and safe and reliable locking, the composite drive locking assembly described in the present application includes at least a driving mechanism and a magnetic locking mechanism. The driving mechanism is arranged on the guide support frame 1 in accordance with the position of each fixed installation frame 2, and the control ends of the driving mechanism and the magnetic locking mechanism are respectively connected to the programmable module 8; each fixed installation frame 2 is moved to a specified position along the corresponding slide 3 under the control of the programmable module 8 according to the extreme wind condition information monitored by the anemometer 7 through the driving mechanism, and each fixed installation frame 2 that has moved into position is locked at the corresponding position of the guide support frame 1 by the magnetic locking mechanism. At this time, the driving mechanism includes at least a plurality of three-in-one drive motors 9 and a plurality of permanent magnet drive shafts, the number of which is equal to the number of fixed installation frames. Each three-in-one drive motor 9 is arranged at a corresponding position of the guide support frame 1 through each permanent magnet drive shaft in correspondence with the position of the corresponding fixed installation frame 2; each fixed installation frame 2 can move back and forth along the slide 3 through the corresponding permanent magnet drive shaft with the cooperation of the power output of the corresponding three-in-one drive motor 9; the control end of each three-in-one drive motor 9 is respectively connected to the programmable module 8. The magnetic locking mechanism includes at least a magnetic terminal part 10 and a magnetic frame part 11. The magnetic terminal part 10 is a magnetizable structure, and the magnetic frame part 11 is a permanent magnet structure. The magnetic terminal part 10 is detachably arranged at the frame position on one side of the end of the guide support frame slide through a control line 12, and the magnetic frame part 11 is fixedly installed on the upper and lower sides of the fixed installation frame; the control end of each magnetic terminal part 10 is respectively connected to the programmable module 8; the fixed installation frame 2 moved into place is locked by the magnetic terminal part 10 and the magnetic frame part 11 with the cooperation of the programmable module 8.A more specific structure is that each permanent magnet drive shaft includes two support bearings 13 and a permanent magnet shaft body 14. The two ends of the permanent magnet shaft body 14 are rotatably arranged around their own axial center lines at corresponding positions of the guide support frame 2 through a support bearing 13. One end of the permanent magnet shaft body 14, the outer surface of which is covered with a polishing piece, extends out of the side wall of the guide support frame 1 after the cooperation of the corresponding support bearing 13 and is fixedly connected to the corresponding three-in-one drive motor 9; a buffer sponge pad 15 and a pressure sensor 16 are also provided on the side walls of the two ends of the guide support frame slide, and the data lines of each pressure sensor 16 are respectively connected to the programmable module 8. The information of each fixed installation frame 2 moving into position is monitored by the corresponding pressure sensor 16; at least one electromagnetic stepless locking rod 17 is also provided on the fixed installation frame 2, and each electromagnetic stepless locking rod 17, whose control end is connected to the programmable module 8, is fixed on the fixed installation frame 2 at intervals of three to five photovoltaic panels 4, and the permanent magnetic shaft body 14 and each electromagnetic stepless locking rod 17 are arranged perpendicular to each other; the partially overlapping fixed installation frames 2 are locked together by the friction between each electromagnetic stepless locking rod 17 and the corresponding permanent magnetic shaft body 14, and the polishing piece on the corresponding permanent magnetic shaft body 14 and the corresponding photovoltaic panel 4. The electromagnetic structure described in this application refers to a structure that has magnetic force when power is applied and disappears when power is turned off.

[0022] In summary, the above technical solution provided by this application also has the following advantages: 1. In strong wind conditions, the wind protection mode is activated, and the upper row of components (i.e. the photovoltaic panel components arranged at a relatively high position through the fixed installation frame) slide downward or the lower row of components (i.e. the photovoltaic panel components arranged at a relatively low position through the fixed installation frame) slide upward to achieve functions such as reducing the windward surface of the components and increasing the stacking thickness of the frame, thereby improving the wind resistance and preventing the components from being blown off as a whole.

[0023] 2. During the sliding process of the components, the sand and dust on the surface of the components will fall off, and the upper row of components will cover the lower row of components, which is beneficial to reduce the accumulation of sand and dust on the surface of the lower row of components.

[0024] 3. No need for maintenance, the protection mode will be activated when high wind pressure is detected, which is automatic and efficient. 4. During installation, the component frame, i.e., the aforementioned fixed mounting frame, is embedded within the bracket, i.e., the aforementioned guide support frame. The component frame can move freely within the frame along the fixed channel without sliding out of the frame, providing a certain degree of positioning for the components. Simultaneously, the edges of the upper and lower rows of components are magnetically connected to the belt, further securing the components and maintaining their stability before they begin to slide. This triple locking mechanism, achieved through terminal buckle locking, permanent magnetic stepless locking lever magnetic attraction, and shaft friction, effectively ensures the stability of the component kit both when it is not sliding and when it is sliding.

[0025] 5. It can be applied to fixed brackets, flat single-axis brackets, and single- and double-column brackets. The specific connection method is to change the steel frame and the main material of the bracket.

[0026] Compared with existing technologies, 1. The technical solution of the present application realizes that a photovoltaic panel group can realize the overall movement of up to 26 or even more photovoltaic panels, with higher efficiency and better integrity. It uses fewer driving points to achieve one-time movement of the components into place, avoiding local sliding failure that may lead to failure of the entire system.

[0027] 2. This solves the existing problem of component frames being torn and damaged, or individual components being blown away, during bracket installation and / or construction due to incomplete component installation and partially untightened bolts, resulting in strong winds on the site. The components in the technical solution of the present invention can be pre-assembled and embedded in the steel outer frame. Once the entire steel frame and components are assembled, they can be directly installed on the bracket system as a whole, avoiding damage caused by partial incomplete installation during strong winds.

[0028] 3. While existing technologies primarily utilize single-connection methods such as bolts or pressure blocks, this technology utilizes a combination of bolts and pressure blocks to connect components, strengthening the connection and improving overall integrity. Furthermore, to achieve magnetic locking and shaft friction locking of individual components at any position during sliding, a permanent magnetic stepless locking lever is arranged at a predetermined distance between the bolts and pressure blocks, enabling stepless locking of the individual components at any position within the shaft.

[0029] 4. Also due to the existence of the steel frame, the overall deadweight load of the upper component system increases and the wind resistance is improved.

[0030] 5. The limitation of the existing technology is that it can only be connected on the roof or on the ground. This invention breaks this limitation and can be connected on the roof or on the ground. On the ground, it can be connected with a single column or a double column, and its application range is very wide.

[0031] 6. In terms of unmanned operation and maintenance, when the anemometer detects high wind pressure, it will turn on the protection mode and lock according to regulations, automatically and efficiently. The details are as follows: a) In the prior art, the docking of components after sliding into place is achieved through physical snaps. However, the technical solution of this application completely relies on sensing changes in wind speed to automatically achieve overlapping of components to avoid strong winds and return to their original position.

[0032] b) The existing technology primarily relies on magnetic attraction at both ends to achieve start and stop. The main problem with this technology is that the photovoltaic panels collide with the ends during movement, which can easily cause damage and hidden cracks in the photovoltaic panels. The improved technical solution of this application is that when the module kit approaches the sponge pads at both ends of the track (i.e., the pressure sensor receives a signal), the rotating shaft immediately stops, ensuring that the outer frame of the module always maintains a reasonable distance from the inner side of the steel frame, and stops smoothly, without the collision and damage that occurs with the existing technology.

[0033] The technical solution of this application is further described below through specific embodiments: The present application provides a technical solution in which double-row vertical components that are generally fixed on a fixed bracket are connected into a whole by a steel frame, and the interior of the steel frame is divided into an upper component and a lower component.

[0034] The photovoltaic panels within each module are connected using compression blocks and double bolts. A steel frame is then placed on the purlins. The steel frame frame is connected to the lower support system, and the purlins are connected using conventional bolts. The photovoltaic panels within each module cannot move relative to each other and are fixed to form a complete structure.

[0035] The assembly frame, or the aforementioned guide support skeleton, is a steel frame. The ends of the magnetic shafts for the upper and lower components are fixed to the steel frame via bearings. The outer rings of the bearings are welded to the steel frame, and the inner sides of the bearings are integrally fixed to the motor, enabling free rotation of the bearings, initiated by the motor.

[0036] The magnetic shafts of the upper and lower components have the same polarity (north or south). The magnetic frame of the component has opposite polarity (north or south). Wire-connected magnetic terminals are attached to the four corners of the steel frame with thin cords, each with an opposite polarity (north or south).

[0037] The left and right sides of the steel frame are component sliding tracks, and the components are restricted in the tracks by the component sliding track grooves.

[0038] Module pressure sensors detect when a module has reached its top or bottom position, enabling the master controller to control the module's start and stop. Sponge pads are installed at both ends of the track to protect the module's outer frame.

[0039] The outer bearing ring is welded to the steel frame, while the inner bearing ring is welded to the magnetic shaft. The inner bearing ring's rotation is controlled by an external motor, which drives the magnetic shaft. The magnetic shafts of the upper and lower components are covered with magnetic belts, which drive the assembly system to slide within the track, providing friction and magnetic attraction during sliding, ensuring assembly stability.

[0040] Under normal conditions, the component kit is attracted to each other through the end of the component magnetic frame (N pole) and the wired magnetic terminal (S pole); the component magnetic frame (N pole) and the magnetic rotating shaft (S pole) are also attracted to each other, and both ends of the component are fixed on the steel frame; at the same time, the component frame and the surface of the magnetic rotating shaft are connected by magnetic attraction / friction, realizing the triple locking of the terminal buckle, belt magnetic attraction and belt friction, effectively ensuring the stability of the component kit when it is not sliding and during sliding.

[0041] An anemometer is installed on the module to monitor the wind speed in the environment in real time. When the wind speed exceeds the design value (e.g., 30m / s) and the duration of the wind speed exceeds the design value (e.g., 10 minutes), and the anemometer detects that the wind speed at the location of the upper / lower assembly is lower, the main controller (i.e., the editable module mentioned above) determines that the wind pressure on the entire assembly can be reduced by moving the upper / lower assembly, and it issues the following command: ① The magnetic pole controller controls the demagnetization of the magnetic terminals on the upper / lower part of the steel frame, while the components and the magnetic shaft remain in the adsorption state; ② The magnetic shaft driving device controls the rotation of the magnetic shaft to move the upper sleeve / lower sleeve assembly toward the opposite side of the steel frame (sliding state).

[0042] When the component pressure sensor detects that the upper component has reached the specified position (the upper end / lower end of the steel frame), and when the pressure sensor detects pressure, the main controller receives an electrical signal and the shaft stops rotating; when the wind speed decreases, the main controller instructs the rotation to reset, thereby starting and stopping the component kit.

[0043] The magnetic shaft drive stops the shaft from rotating, and the magnetic pole controller restores the magnetism of the magnetic terminals. This allows the upper and lower components to overlap, reducing the windward surface of the entire module system. The combined thickness of the upper and lower components increases, improving the overall wind resistance of the module system and effectively preventing module damage.

[0044] This application also provides another structural design to improve the wind resistance of the components, that is, by adjusting the inclination angle of the steel frame to keep the upper and lower sets of components consistent with the wind direction, so that the entire structure only bears wind force in the thickness direction, achieving the purpose of minimizing the windward surface. The specific structure is as follows: The hinge is welded or bolted to the steel frame's frame on the upper side (the side with the assembly higher off the ground), and the other side is bolted to the support purlin. When the steel frame's lower side (the side with the assembly lower off the ground) is spirally raised, the hinge drives the upper side of the steel frame upward, leveling the entire steel frame and entering high wind protection mode. The high wind protection mode is determined in combination with the wind speed detected by the anemometer. According to the above settings, when the wind speed is detected to exceed the design value (such as 30m / s) and the continuous duration exceeds the design value (such as 10mins), the main controller determines that the wind pressure on the entire set of components can be reduced by moving the upper / lower sets of components; and when the anemometer monitors that the wind speed exceeds 40m / s, the upper and lower sets of components not only overlap, but also start to lift the entire steel frame, so that the entire steel frame and components are in a flat state, entering the high wind protection state. After waiting for the wind speed to fall below the set value, the steel frame rotates back to the original inclination angle, and at the same time, the upper and lower sets of components slide out according to the wind speed conditions and return to the original non-overlapping state.

[0045] A spiral-reducing lifting shaft, or camshaft, is mounted within the steel frame of the bracket. Its ends are secured to the steel frame's two sides in the same manner as the magnetic belt's rotating bearings. The spiral-reducing lifting shaft is located on the lower side (bottom edge) of the assembly kit. Two reducing devices are welded to each end of the spiral-reducing lifting shaft. The reducing devices consist of a straight section and a reducing section, which are welded to the lifting shaft.

[0046] When the anemometer detects wind speeds exceeding 40 m / s, the spiral reducer shaft begins to rotate, and the two reducers drive the lower edge of the steel frame to rise to the maximum diameter of the reducer. This diameter is sufficient to ensure that the steel frame is raised to a level position with the rear edge (i.e., the high side) of the steel frame and stops. At this point, the entire steel frame and components are flat at 0 degrees, entering extreme wind protection mode.

[0047] Adjusting the steel frame's tilt angle can also be achieved using hydraulic push rods. The higher end is hinged to the bottom bracket, while the lower end is connected to the bottom bracket via a hydraulic push rod. To adjust the steel frame's tilt angle, simply activate the hydraulic push rod to raise the lower end to the same height as the higher end. The hydraulic push rods are also activated by the master controller in conjunction with the anemometer.
