Description

Technical Field

[0001] This invention relates to the field of photovoltaic panel support technology, specifically to a wind-resistant double-lever pressure block photovoltaic fixing mechanism with automatic pressure relief. Background Technology

[0002] With the promotion of energy conservation and environmental protection, more and more people are installing photovoltaic panels on the rooftops of buildings to convert solar energy into electricity. Photovoltaic brackets are commonly used to install and secure these panels.

[0003] Currently, existing photovoltaic panel supports have two sliding sleeves on a horizontal plate, which are then connected to clamps for holding the photovoltaic panels. After prolonged use in the open air, the surface of the horizontal plate will rust, which will hinder the sliding of the sliding sleeves on the surface of the horizontal plate, or even prevent them from sliding. This makes it impossible to repair and replace damaged parts in a timely manner. Moreover, most existing photovoltaic panel supports are fixed structures, so the photovoltaic panels are also fixed after installation. This means that the photovoltaic panels cannot release pressure in time when facing strong winds, which increases the risk of the fixed support overturning. At the same time, the fixed support will be subjected to strong wind loads for a long time, which will accelerate the fatigue of the support materials, leading to loosening or breakage of the connectors. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a wind-resistant, double-lever, pressure-blocking photovoltaic fixing mechanism with automatic pressure relief.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: This invention discloses an automatically depressurized, wind-resistant, double-lever, pressure-block type photovoltaic fixing mechanism, comprising: The support column has a main assembly shaft fixedly connected to its top by multiple bolts. The bottom of the main assembly shaft has a groove. The surfaces at both ends of the main assembly shaft are provided with a displacement assembly that slides with the surface.

The adjustment unit is disposed on the surfaces at both ends of the main assembly shaft, and the grinding unit is installed on both sides of the adjustment unit. The pressure relief assembly includes an automatic pressure relief unit, a docking unit, and a pressure regulating unit. The automatic pressure relief unit is installed on the top of the adjusting unit, the docking unit is installed on the side of the front end of the automatic pressure relief unit, and the pressure regulating unit is installed on the surface of the docking unit and the automatic pressure relief unit.

[0006] As a preferred embodiment of the present invention, the adjustment unit includes two adjustment slides. The inner cavities at the lower ends of the two adjustment slides are respectively sleeved on the surfaces at both ends of the main assembly shaft. Each adjustment slide has a threaded adjustment hole on its lower surface. A positioning screw is threadedly connected to the inner wall of each adjustment hole. A handle is installed on the top of the side of each adjustment slide away from the station column.

[0007] As a preferred embodiment of the present invention, the grinding unit includes four internal slots, with each pair of internal slots respectively opened on both sides of the lower end of each adjusting slide. The inner wall of each internal slot is rotatably connected to a synchronous sleeve via a bearing. A driven gear is fixedly sleeved on the outer surface of the end of each synchronous sleeve near the adjusting slide. A limiting sleeve is embedded in the upper surface of the end of each synchronous sleeve away from the adjusting slide. A positioning grinding plate that slides with the inner wall of each limiting sleeve is inserted into the inner cavity of the lower end of each limiting sleeve. An adjusting screw that is threadedly connected to the inner wall of the positioning grinding plate is embedded in the top of each limiting sleeve via a bearing.

[0008] As a preferred embodiment of the present invention, a dual-axis motor is fixedly installed on the bottom surface of the inner cavity at the upper end of each adjustment slide, and a synchronous gear that meshes with the driven gear is fixedly sleeved on the output shaft surface at both ends of each dual-axis motor.

[0009] As a preferred embodiment of the present invention, the lower surface of each of the positioning grinding plates at the end away from the adjusting slide is provided with an arc surface.

[0010] As a preferred embodiment of the present invention, the automatic pressure relief unit includes two support columns. The lower surfaces of the two support columns are fixedly connected to the upper surface of each adjusting slide. The front end of each support column is hinged to a pressure lever via a pin. The upper end of each pressure lever is hinged to a front pressure block via a pin. The inner wall of the rear end of each front pressure block is threaded with a pressure relief inner column. The surface of the rear end of each pressure relief inner column is fitted with a pressure relief sleeve that slides against its inner wall. The outer surface of the rear end of each pressure relief sleeve is threaded with a rear pressure block. Each rear pressure block is hinged to the rear end of each support column via a pin with an adjusting lever.

[0011] As a preferred embodiment of the present invention, each of the pressure relief inner column and pressure relief sleeve has a retaining ring fixedly connected to the outer surface of the end away from each other for loading and unloading.

[0012] As a preferred embodiment of the present invention, a pressure relief spring is sleeved on the outside of each pressure relief sleeve, and a mating block is fixedly connected to the front and rear ends of each pressure relief spring. A positioning screw is threadedly connected to the inner wall of each mating block. The ends of the positioning screws at the front and rear are respectively threadedly connected to the opposite sides of the front and rear pressure blocks. A front baffle for limiting the pressure lever is fixedly connected to the upper surface of the front end of each support column, and a rear baffle for limiting the adjustment lever is fixedly connected to the upper surface of the rear end of each support column.

[0013] As a preferred embodiment of the present invention, the docking unit includes two positioning plates. The side of each positioning plate that is close to each other is fixedly connected to the side of each pressure lever. Each positioning plate has two main mounting holes of different shapes on its front side. Each positioning plate has multiple side mounting holes on its surface away from the pressure lever. Each side mounting hole has a docking bolt threaded to its inner wall.

[0014] As a preferred embodiment of the present invention, the pressure regulating unit includes a wind pressure sensor, which is fixedly installed on the front of the positioning plate on the left side. Two rotary cylinders are fixedly installed at the rear of the two supporting columns that are far apart from each other, and the piston rod of each rotary cylinder is fixedly connected to the side of the lower end of each adjusting lever.

[0015] The beneficial effects of this invention are: 1. This type of automatically depressurized, wind-resistant, double-lever, pressure-block photovoltaic fixing mechanism, through a set of shifting components, first controls the left and right movement of two adjusting slides. The left and right movement of the adjusting slides controls the distance between the two positioning plates. Then, the positioning screw is controlled to rotate clockwise so that its top end fully contacts the groove surface of the main mounting shaft. This quickly completes the positioning of the two positioning plates after adjustment, facilitating the fixing of photovoltaic panels of different sizes and improving the practicality of the fixing mechanism. Finally, controlling the start of the dual-axis motor drives two synchronous gears to rotate simultaneously. The simultaneous rotation of the two synchronous gears... It can drive two driven gears and two synchronous sleeves to rotate simultaneously. The rotation of the two synchronous sleeves can drive two limit sleeves and two positioning grinding plates to rotate simultaneously. The rotation of the positioning grinding plates can grind the surface of the main assembly shaft. Pulling the two handles to both sides can drive the two adjusting slides to move. The movement of the two adjusting slides can drive the rotating positioning grinding plates to move. In this way, the positioning grinding plates can achieve all-round grinding of the surface of the main assembly shaft, thereby improving the lubrication of the surface of the main assembly shaft, which facilitates the maintenance and replacement of components in the shifting assembly and pressure relief assembly.

[0016] 2. This type of automatically depressurized, wind-resistant, double-lever, pressure-block photovoltaic fixing mechanism, through its docking unit, allows for easy connection between the main mounting hole and the positioning plate. The side mounting hole then aligns with the mounting holes on the side of the photovoltaic panel. By controlling the forward rotation of the docking bolts, the photovoltaic panel can be positioned in a lateral position. The combined use of the main and side mounting holes enables positioning of the photovoltaic panel in multiple directions, allowing the fixing mechanism to adapt to different types of photovoltaic panels and improving the user experience.

[0017] 3. This type of wind-resistant, double-lever, pressure-block photovoltaic fixing mechanism with automatic pressure relief utilizes an automatic pressure relief unit. First, wind pressure on the photovoltaic panel causes the upper end of the positioning plate to move backward. This backward movement of the positioning plate rotates the upper end of the pressure lever, which in turn moves the front pressure block and the pressure-relief inner column backward simultaneously. The backward movement of the front pressure block compresses the pressure-relief spring, and the pressure relief unit during this compression process relieves the wind pressure on the photovoltaic panel. This automatic pressure relief mechanism first improves the service life of the fixing mechanism. Then, the positioning screw is turned to reverse and disengage it from the surfaces of the front and rear pressure blocks, thus disassembling the pressure-relief spring. Finally, the pressure-relief inner column is reversed to disengage from the surface of the front pressure block, fully disassembling the pressure-relief spring and facilitating its replacement. Replacing the pressure-relief spring allows for continuous use of the pressure relief component, further extending the service life of the fixing mechanism.

[0018] 4. This type of automatically depressurized, wind-resistant, double-lever pressure block photovoltaic fixing mechanism, through the installation of a rotary cylinder and a wind pressure sensor, firstly, the wind pressure sensor can detect the wind pressure on the front of the photovoltaic panel. When the wind pressure exceeds the preset value, it will control the rotary cylinder to start. The start of the rotary cylinder can drive the adjusting lever to rotate forward. The forward rotation of the adjusting lever can drive the rear pressure block to press the pressure relief spring forward. By compressing the pressure relief spring, the compressive strength of the positioning plate on the photovoltaic panel can be improved. The reduced swing amplitude of the front pressure block will reduce the swing amplitude of the photovoltaic panel, effectively reducing the damage to the photovoltaic panel caused by the fixing mechanism and greatly improving the practicality of the photovoltaic panel fixing mechanism.

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] Example: Figures 1-14 As shown, the present invention discloses an automatic pressure-relieving, wind-resistant, double-lever, pressure-blocking photovoltaic fixing mechanism, comprising: a support column 1, a main mounting shaft 2 fixedly connected to the top of the support column 1 by multiple bolts, a groove provided at the bottom of the main mounting shaft 2, and a shifting component 3 slidably mounted on the surfaces of both ends of the main mounting shaft 2; a pressure-relieving component 4 for automatically relieving pressure on the photovoltaic panel is connected to the top of the shifting component 3; the shifting component 3 includes an adjustment unit and a grinding unit, the adjustment unit is disposed on the surfaces of both ends of the main mounting shaft 2, and the grinding unit is installed on both sides of the adjustment unit; the pressure-relieving component 4 includes an automatic pressure-relieving unit, a docking unit, and a pressure-regulating unit, the automatic pressure-relieving unit is installed on the top of the adjustment unit, the docking unit is installed on the side of the front end of the automatic pressure-relieving unit, and the pressure-regulating unit is installed on the surfaces of the docking unit and the automatic pressure-relieving unit.

[0023] The adjustment unit includes two adjustment slides 301. The inner cavities at the lower ends of the two adjustment slides 301 are respectively sleeved on the surfaces at both ends of the main shaft 2. Each adjustment slide 301 has a threaded downward adjustment hole 302 on its lower surface. A positioning screw 303 is threadedly connected to the inner wall of each downward adjustment hole 302. A handle 304 is installed on the top of each adjustment slide 301 on the side away from the station column 1.

[0024] The grinding unit includes four internal slots 305. Each pair of internal slots 305 is located on the two sides of the lower end of each adjusting slide 301. The inner wall of each internal slot 305 is rotatably connected to a synchronous sleeve 306 via a bearing. A driven gear 307 is fixedly sleeved on the outer surface of the end of each synchronous sleeve 306 near the adjusting slide 301. A limiting sleeve 308 is embedded in the upper surface of the end of each synchronous sleeve 306 away from the adjusting slide 301. A positioning grinding plate 309 that slides against the inner wall of each limiting sleeve 308 is inserted into the inner cavity at the lower end of each limiting sleeve 308. An adjusting screw 310 that is threadedly connected to the inner wall of the positioning grinding plate 309 is embedded in the top of each limiting sleeve 308 via a bearing. A dual-axis motor 311 is fixedly installed on the bottom surface of the upper inner cavity of each adjusting slide 301. A synchronous gear 312 that meshes with the driven gear 307 is fixedly sleeved on the output shaft surfaces at both ends of each dual-axis motor 311.

[0025] Each positioning grinding plate 309 has an arc surface on its lower surface at the end away from the adjusting slide 301.

[0026] The curved surface allows the positioning grinding plate 309 to adapt to the rusted surface of the main shaft 2, preventing it from being blocked by the rusted surface.

[0027] The automatic pressure relief unit includes two support columns 401. The lower surfaces of the two support columns 401 are fixedly connected to the upper surfaces of each adjusting slide 301. The front end of each support column 401 is hinged to a pressure lever 402 by a pin. The upper end of each pressure lever 402 is hinged to a front pressure block 403 by a pin. The inner wall of the rear end of each front pressure block 403 is threaded with a pressure relief inner column 404. The surface of the rear end of each pressure relief inner column 404 is fitted with a pressure relief sleeve 405 that slides against its inner wall. The outer surface of the rear end of each pressure relief sleeve 405 is threaded with a rear pressure block 406. Each rear pressure block 406 is hinged to the rear end of each support column 401 by a pin with an adjusting lever 407.

[0028] Each pressure relief inner column 404 and pressure relief sleeve 405 has a retaining ring fixedly connected to the outer surface of the opposite end for loading and unloading.

[0029] The retaining ring allows the disassembly tool to loosen the pressure relief inner column 404 and the pressure relief sleeve 405, thereby accelerating the installation and removal of the pressure relief inner column 404 and the pressure relief sleeve 405.

[0030] Each pressure relief sleeve 405 is fitted with a pressure relief spring 408. Each pressure relief spring 408 has a mating block 409 fixedly connected to its front and rear ends. Each mating block 409 has a positioning screw 410 threadedly connected to its inner wall. The ends of the positioning screws 410 at the front and rear are threadedly connected to the opposite sides of the front pressure block 403 and the rear pressure block 406, respectively. Each support column 401 has a front baffle 411 fixedly connected to its upper front surface for limiting the pressure lever 402. Each support column 401 has a rear baffle 412 fixedly connected to its upper rear surface for limiting the adjustment lever 407.

[0031] The docking unit includes two positioning plates 413. The side of each positioning plate 413 that is close to each other is fixedly connected to the side of each pressure lever 402. Each positioning plate 413 has two main mounting holes 414 of different shapes on its front side. Each positioning plate 413 has multiple side mounting holes 415 on its surface away from the pressure lever 402. Each side mounting hole 415 has a docking bolt 416 threadedly connected to its inner wall.

[0032] The pressure regulating unit includes a wind pressure sensor 417, which is fixedly installed on the front of the positioning plate 413 on the left side. Two rotary cylinders 418 are fixedly installed behind the two support columns 401 at opposite ends, and the piston rod of each rotary cylinder 418 is fixedly connected to the side of the lower end of each adjusting lever 407.

[0033] During operation, firstly, the two adjusting slides 301 are moved left and right. This movement controls the distance between the two positioning plates 413. Then, the positioning screw 303 is rotated clockwise so that its top end fully contacts the groove surface of the main mounting shaft 2. This quickly completes the positioning of the two positioning plates 413 after adjustment, facilitating the installation of photovoltaic panels of different sizes. The main mounting hole 414 allows for easy fixing of the photovoltaic panel to the positioning plate 413, while the side mounting hole 415 aligns with the side mounting holes of the photovoltaic panel. Rotating the connecting bolt 416 clockwise allows for side positioning of the photovoltaic panel. The combined use of the main mounting hole 414 and the side mounting hole 415 enables positioning of the photovoltaic panel in multiple directions. Wind pressure on the photovoltaic panel causes the upper end of the positioning plate 413 to move backward. This backward movement of the positioning plate 413 causes the upper end of the pressure lever 402 to rotate backward. Rotating lever 402 backward causes the front pressure block 403 and the pressure relief inner column 404 to move backward simultaneously. The backward movement of the front pressure block 403 compresses the pressure relief spring 408, which relieves the wind pressure on the photovoltaic panel. This allows the fixing mechanism to automatically relieve pressure on the installed photovoltaic panel, thus improving the service life of the fixing mechanism. Finally, the wind pressure sensor 417 can detect the wind pressure on the front of the photovoltaic panel. When the wind pressure exceeds the preset value, it controls the rotary cylinder 418 to start. The start of the rotary cylinder 418 causes the adjusting lever 407 to rotate forward. The forward rotation of the adjusting lever 407 causes the rear pressure block 406 to compress the pressure relief spring 408. By contracting the pressure relief spring 408, the compressive strength of the positioning plate 413 on the photovoltaic panel can be improved. The reduced swing amplitude of the front pressure block 403 reduces the swing amplitude of the photovoltaic panel, effectively reducing the damage to the photovoltaic panel caused by the fixing mechanism. Disassembly of the components of the fixing mechanism: First, start the dual-axis motor 311 to drive the two synchronous gears 312 to rotate simultaneously. The rotation of the two synchronous gears 312 drives the two driven gears 307 and the two synchronous sleeves 306 to rotate simultaneously. The rotation of the two synchronous sleeves 306 drives the two limit sleeves 308 and the two positioning grinding plates 309 to rotate simultaneously. The rotation of the positioning grinding plates 309 can grind the surface of the main shaft 2. Then, pull the two handles 304 to both sides to move the two adjusting slides 301. The movement of the two adjusting slides 301 can move the rotating positioning grinding plates 309. In this way, the positioning grinding plates 309 can achieve all-round grinding of the surface of the main shaft 2, thereby improving the lubrication of the surface of the main shaft 2, so as to facilitate the maintenance and replacement of the components in the shifting assembly 3 and the pressure relief assembly 4. First, twist the positioning screw 410 to reverse it and disengage it from the surfaces of the front pressure block 403 and the rear pressure block 406. This completes the disassembly of the pressure relief spring 408. Then, control the pressure relief inner column 404 to reverse it and disengage it from the surface of the front pressure block 403. At this time, flip the pressure relief sleeve 405 upward to move it fully away from the front pressure block 403. This completes the disassembly of the pressure relief spring 408, making it easy to replace with a new pressure relief spring 408. By replacing the pressure relief spring 408, the pressure relief assembly 4 can be used continuously. Then, control the pressure relief sleeve 405 to reverse it and disengage it from the rear pressure block 406. This completes the separation of the pressure relief sleeve 405 from the pressure relief inner column 404, making it easy to replace the pressure relief structure.

[0034] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
