Description

Technical Field

[0001] This utility model relates to the field of photovoltaic bracket installation technology, specifically a detachable base for photovoltaic brackets on flat roofs. Background Technology

[0002] In the field of photovoltaic power generation technology, flat roofs are a common location for installing photovoltaic support systems due to their large area and convenient installation. Currently, the photovoltaic support bases used on flat roofs have the following defects and problems that need to be solved in practical applications: Most existing bases and supports are usually connected by bolts. This connection method requires the use of professional tools to tighten or disassemble each bolt individually during installation, subsequent maintenance, repair, or component replacement. The operation process is cumbersome, time-consuming, labor-intensive, and inefficient, and cannot meet the needs of rapid deployment and convenient maintenance. Traditional base designs are often single-function, mainly providing basic support, and lack reinforcement structures specifically for strong winds and other severe weather. This makes the entire photovoltaic support system prone to swaying, tilting, or even structural deformation or damage when encountering strong winds. This not only poses safety hazards but also affects the power generation efficiency of photovoltaic modules and the long-term reliability of operation. In view of the above problems, this case was developed through in-depth research. Utility Model Content

[0022] Example 1

[0023] A preferred embodiment of the detachable base for photovoltaic brackets on flat roofs provided by this utility model is, for example... Figure 1 and Figure 2As shown: A detachable base for a photovoltaic bracket on a flat roof includes: a base body 1; fixing seats 8 evenly installed on the inner walls of the four corners of the base body 1, each fixing seat 8 having a mounting groove 10 at its top, mounting blocks 5 installed on the inner side of each mounting groove 10, and a bracket body 3 connected to the top of each mounting block 5, with fixing rings 4 installed on the outer wall below the bracket body 3; a windproof mechanism 2 evenly installed on the outer side of the fixing rings 4 via a rotating shaft, the windproof mechanism 2 serving to support the bracket body 3 against wind; and a quick-release mechanism 11 evenly installed on the outer wall above the fixing seats 8, the quick-release mechanism 11 serving to quickly detach and assemble the bracket body 3 and the fixing seats 8.

[0024] It should be noted that the existing technology for detachable photovoltaic brackets for flat roofs has several drawbacks. Most existing brackets and supports are directly fastened with bolts. This method requires specialized tools for tightening or disassembling individual bolts during installation, maintenance, repair, or component replacement. This process is cumbersome, time-consuming, labor-intensive, and inefficient, failing to meet the needs for rapid deployment and convenient maintenance. Traditional bracket designs are often functionally limited, primarily providing basic support and lacking reinforcement structures specifically designed for strong winds and other severe weather conditions. This makes the entire photovoltaic bracket system prone to swaying, tilting, and even structural deformation or damage when encountering strong winds, posing safety hazards and affecting the power generation efficiency and long-term operational reliability of the photovoltaic modules.

[0025] In this embodiment, the stable connection between the base body 1 and the fixing seat 8, combined with the fitting structure of the mounting groove 10 and the mounting block 5, enables reliable load bearing of the bracket body 3. The triangular support design of the windproof mechanism 2 effectively enhances the wind resistance stability of the bracket system. At the same time, the quick-release mechanism 11's buckle locking and locking functions enable quick disassembly and reliable fixation of the bracket. All mechanisms work together to provide a flat roof photovoltaic bracket base solution that is structurally stable, easy to install, highly wind-resistant, and easy to maintain.

[0026] In a further preferred embodiment of this utility model, the windproof mechanism 2 includes: connecting blocks 206 that are uniformly and movably installed on the outside of the fixed ring 4 via rotating shafts, and supporting inclined rods 201 are installed on the inner side of each connecting block 206. The bottom ends of the supporting inclined rods 201 are connected to the inner wall of the base body 1 via rotating shafts, and the tilt angle of the windproof mechanism 2 is 30°.

[0027] In this embodiment, the windproof mechanism 2 forms a stable triangular support structure through the connection between the support diagonal rod 201, the base body 1, and the fixing ring 4, which effectively enhances the wind resistance of the support body 3. The support diagonal rod 201 is connected to the base body 1 and the connecting block 206 by a rotating shaft, which makes the windproof mechanism 2 easy to install. The tilt angle of the windproof mechanism 2 is set to 30°. This angle has been optimized to maximize the dispersion of wind force on the support body 3 while ensuring the support strength, thereby improving the stability of the overall structure. In addition, the fastening method of the screw 202 and the nut 205 facilitates the disassembly and assembly of the support diagonal rod 201.

[0028] In a further preferred embodiment of the present invention, a first mounting hole 203 is provided above the support diagonal rod 201, and a second mounting hole 204 is provided on the outer wall of both ends of the connecting block 206. A screw 202 is installed through the inner side of the second mounting hole 204 and the first mounting hole 203, and a nut 205 is threaded on the outer wall of the screw 202 on the outer side of the connecting block 206.

[0029] In this embodiment, the connection between the support rod 201 and the connecting block 206 is achieved by the first mounting hole 203 above the support rod 201 and the second mounting holes 204 at both ends of the connecting block 206. The screw 202 passes through the first mounting hole 203 and the second mounting hole 204, and a nut 205 is threaded onto the screw 202 on the outside of the connecting block 206 to form a firm mechanical connection.

[0030] Example 2

[0031] Based on Embodiment 1, a preferred embodiment of the detachable base for photovoltaic supports on flat roofs provided by this utility model is, for example... Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown: The quick-release mechanism 11 includes: a latch frame 1103 evenly installed on the outer wall above the fixed base 8. The inner wall of the latch frame 1103 is movably installed with a locking handle 1105 via a pivot. The inner side of the locking handle 1105 is movably installed with a connecting rod 1106, and one end of the connecting rod 1106 is connected to a hanging ring 1102. The outer wall of the bracket body 3 is evenly connected with hooks 1101 that cooperate with the hanging rings 1102.

[0032] In this embodiment, the hanging ring 1102 on the latch bracket 1103 is aligned with the hook 1101 and hooked in. Then, the locking handle 1105 is pressed down, and the connecting rod 1106 is pulled by leverage to make the hanging ring 1102 and the hook 1101 tightly fastened and form a stable lock. When disassembling, the connection can be quickly released by simply pulling up the locking handle 1105. This mechanism is easy to operate and requires no tools, which significantly improves the efficiency of installation and maintenance, while ensuring the reliability and safety of the connection.

[0033] In a further preferred embodiment of the present invention, the locking blocks 1104 installed on both sides above the locking handle 1105, and the inner walls of the latch brackets 1103 below the locking blocks 1104 are all connected to dampers 1107, and the outer walls of one end of the dampers 1107 are all equipped with return springs 1108.

[0034] In this embodiment, the locking blocks 1104 installed on both sides of the locking handle 1105, together with the damper 1107 and the return spring 1108 connected to the inner wall of the latch bracket 1103, constitute a reliable locking and reset system. When the locking handle 1105 is pressed down to the locked position, the locking blocks 1104 press on the locking handle 1105 to perform the locking function. When the lock is released, the locking blocks 1104 can be pulled outward, and the damper 1107 and the return spring 1108 are squeezed and deformed.

[0035] In a further preferred embodiment of the present invention, positioning grooves 9 are uniformly arranged on the inner wall of the mounting groove 10, and positioning blocks 6 that cooperate with the positioning grooves 9 are uniformly connected to the outer wall below the bracket body 3.

[0036] In this embodiment, the positioning groove 9 set on the inner wall of the mounting groove 10 and the positioning block 6 on the lower outer wall of the bracket body 3 cooperate with each other to achieve quick and accurate pre-positioning between the bracket body 3 and the base. During installation, it is only necessary to align the positioning block 6 and embed it into the corresponding positioning groove 9 to effectively limit the horizontal displacement of the bracket body 3 and prevent it from rotating or misaligning. This provides an accurate basis for subsequent quick locking operations. This positioning structure effectively improves the convenience of installation and the success rate of the first installation, while enhancing the bracket's wind and vibration resistance during long-term use and ensuring the stability of the overall structure.

[0037] In a further preferred embodiment of the present invention, a magnetic ring 7 is embedded in the lower part of the mounting block 5 and inside the mounting groove 10, and the magnetic poles of opposite sides of the magnetic ring 7 are different.

[0038] In this embodiment, the magnetic ring 7 embedded below the mounting block 5 and inside the mounting groove 10 is arranged with opposite poles facing each other. When the two are close, they generate a magnetic force that attracts each other. This magnetic attraction structure can provide initial positioning and holding force when the bracket body 3 is installed, guiding the positioning block 6 to slide accurately into the positioning groove 9, effectively preventing displacement or detachment during the installation process, and significantly improving the convenience and accuracy of installation. At the same time, when the quick release mechanism 11 is not locked, the magnetic force can provide auxiliary fixation for the bracket, avoiding positional changes caused by slight disturbances, and enhancing the stability and reliability of the installation process.

[0039] In summary, the quick-release mechanism 11 enables rapid assembly and disassembly of the bracket body 3 and the base body 1. The cooperation of the latch bracket 1103, locking handle 1105, hanging ring 1102, and hook 1101, combined with the damper 1107 and return spring 1108, ensures stable locking and convenient operation. Furthermore, the triangular support structure of the support diagonal rod 201 and connecting block 206 in the windproof mechanism 2, along with the fastening of the screw 202 and nut 205, effectively enhances the wind resistance of the bracket. At the same time, the precise pre-positioning is achieved through the cooperation of the positioning block 6 and positioning groove 9, and the auxiliary adsorption effect of the magnetic ring 7 further improves the accuracy and stability of the installation. The synergistic effect of each mechanism constitutes a flat roof photovoltaic bracket base that is easy to install, structurally stable, wind-resistant, and easy to disassemble and maintain.
