Description

Technical Field

[0001] This invention belongs to the field of photovoltaic panel installation technology, and particularly relates to an overhead roof photovoltaic panel laying device. Background Technology

[0002] Photovoltaic panels (also known as solar panels) are devices that use semiconductor materials to directly convert sunlight into electrical energy. Their core principle is based on the photovoltaic effect, which achieves photoelectric conversion through a PN junction combining P-type and N-type semiconductors. When installed on a roof, they are usually installed in an overhead manner, which requires mounting the photovoltaic panels onto a mounting frame. However, since the width of the mounting frame is less than the length of the photovoltaic panel and the installation space is limited, it is not convenient to move the photovoltaic panels from below the mounting frame to above it. A structure that facilitates the installation of photovoltaic panels is proposed. Summary of the Invention

[0008] A further technical solution: The base is provided with a limiting component to prevent the photovoltaic panel from sliding. The limiting component includes a stop rod and an anti-slip component. Two stop rods are symmetrically arranged on both sides of the long side of the photovoltaic panel, and a rubber cylinder is rotatably provided on the outer wall of the stop rod. The stop rod and the rubber cylinder are coaxial. The lower end face of the stop rod is rotatably connected to the upper surface of the guide rod, and the two guide rods are horizontally arranged in the base.

The abutment rod is rotatably mounted on the guide rod, and the lower end face of the abutment rod extends through the lower end face of the guide rod.

[0011] A further technical solution: The lower end face of the abutment is connected to a belt, the other side of the belt is connected to a short rod, and the upper end face of the short rod is rotatably connected to a guide rod.

[0013] Beneficial effects This invention provides an overhead roof photovoltaic panel installation device, which has the following advantages compared with the prior art: 1. After the user places the photovoltaic panel centered on the base surface, because the long side of the photovoltaic panel is larger than the short side of the mounting frame, the photovoltaic panel cannot be placed on the mounting frame from the lower surface. Due to the limited space on the mounting frame, the photovoltaic panel will be blocked by the adjacent photovoltaic panel after rotating 30 degrees, making it still impossible to place on the mounting frame. At this time, the user can rotate the connecting seat horizontally. Then the connecting plate will start to rotate upward with the connection point between it and the connecting seat as the fulcrum, so that the photovoltaic panel above it is tilted. When the angle between the photovoltaic panel and the connecting seat is 70°, the connecting seat will rotate 90° simultaneously. Then the user can activate multiple cylinders to make the photovoltaic panel rise vertically, so that its short side passes through the lower end of the mounting frame first, until the other short side of the photovoltaic panel is also above the mounting frame. At this time, the connecting plate can be reset. That is, the photovoltaic panel rotates 30 degrees until its long side is parallel to the short side of the mounting frame. Then the user can use the cylinders to drive the photovoltaic panel down, so that the mounting frame blocks the photovoltaic panel, and the end face of the photovoltaic panel is stuck on its long side. 2. The user starts the motor connected to the lead screw, causing it to rotate at a constant speed. At this time, the threaded connecting block on the lead screw begins to move linearly along the sliding connection between the lead screw and the mounting bracket. At this time, the push rod begins to lift the connecting seat upward under the action of the connecting block. The connecting seat then begins to rotate upward with the connection point between it and the connecting plate as the fulcrum, thus gradually tilting the photovoltaic panel. Simultaneously, the bevel gear fixedly connected to the lead screw rotates synchronously during the rotation of the lead screw. The bevel gear then drives the bevel gear B that meshes with it, which in turn drives the shaft fixedly connected to its axis to rotate at a constant speed. This causes the transmission gear fixedly connected to its lower end to roll on the gear ring that meshes with it. At this time, the connecting plate begins to rotate horizontally, thus adjusting the tilt of the photovoltaic panel while rotating it, until the long side of the photovoltaic panel is parallel to the long side of the mounting bracket. At this point, the tilt of the photovoltaic panel is 70°. 3. Before rotating the lead screw, the user should start the electric actuator, causing its output shaft to push the corresponding guide rod. This gradually increases the distance between the rotating abutment on the guide rod and the long side of the photovoltaic panel. The user can then start the motor, causing the connecting block fixedly connected to its output shaft to rotate. At this point, the abutment begins to move gradually towards the short side of the photovoltaic panel. When the two abutments are on opposite sides of the short side of the photovoltaic panel, the electric actuator can then be started in reverse, causing the two guide rods to move towards each other. During this process, the gear gradually slides onto the gear ring, and the rubber sleeve is then pressed tightly against the short side of the photovoltaic panel. As the guide rod continues to rotate, the rubber sleeve remains pressed tightly against the short side of the photovoltaic panel, compressing it until it is firmly attached to the panel. The short side of the bracket is positioned and protected by the bracket. As it continues to rotate, the gears roll on the gear ring, and with the help of the belt, the abutment rotates at a constant speed. At this time, the semi-circular disk fixed at the top begins to rotate to the upper surface of the photovoltaic panel. That is, the lower surface of the semi-circular disk gradually presses against the upper surface of the photovoltaic panel. At this time, the rubber sleeve and the semi-circular disk cooperate to provide bidirectional limiting for the photovoltaic panel, thereby preventing the photovoltaic panel from sliding along the base after it rotates and tilts. This effectively prevents the short side of the photovoltaic panel from hitting the ground. At the same time, after the photovoltaic panel returns to the position where its long side is parallel to the short side of the mounting frame, the two abutment rods are positioned on both sides of the long side of the photovoltaic panel, thus preventing the short side of the photovoltaic panel from being stuck on the long side of the mounting frame after it descends.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0022] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0023] Please see Figures 1-6 According to one embodiment of the present invention, an overhead roof photovoltaic panel installation device includes a mounting frame 101, a photovoltaic panel 201 disposed below the mounting frame 101, and the length of the lower surface of the photovoltaic panel 201 being greater than the width of the mounting frame 101. The photovoltaic panel 201 is arranged parallel to the upper surface of the base 202, and connecting plates 203 are symmetrically fixedly connected to both sides of the base 202. One of the connecting plates 203 is rotatably connected to a connecting seat 204, and the lower end face of the other base 202 is horizontally overlapped with the upper surface of the connecting seat 204. A shaft 208 is fixedly connected to the lower surface of the connecting seat 204, and the lower end face of the shaft 208 is rotatably connected to a bottom cylinder 209. A plurality of cylinders 2001 are horizontally fixedly connected to the lower end face of the bottom cylinder 209.

[0024] In the above embodiment, after the user places the photovoltaic panel 201 centered on the surface of the base 202, because the long side of the photovoltaic panel 201 is larger than the short side of the mounting bracket 101, the photovoltaic panel 201 cannot be placed on the lower surface of the mounting bracket 101. Furthermore, due to the limited space on the mounting bracket 101, after rotating 90 degrees, the photovoltaic panel 201 will be blocked by the adjacent photovoltaic panel, preventing it from being placed on the mounting bracket 101. At this point, the user can rotate the connecting seat 204 horizontally. The connecting plate 203 then begins to rotate upwards with its connection point with the connecting seat 204 as the fulcrum, causing the photovoltaic panel 201 above it to tilt. When the photovoltaic panel 201 and... After the included angle between the connecting seats 204 is 70°, the connecting seats 204 rotate 90° synchronously. At this time, the user can activate multiple cylinders 2001, so that the photovoltaic panel 201 rises vertically and its short side passes through the lower end face of the mounting frame 101 first, until the other short side of the photovoltaic panel 201 is also above the mounting frame 101. At this time, the connecting plate 203 can be reset. That is, the photovoltaic panel 201 rotates to the point where its long side is parallel to the short side of the mounting frame 101. Then, the user can use the cylinders 2001 to drive the photovoltaic panel 201 down, so that the mounting frame 101 blocks the photovoltaic panel 201, thus locking the end face of the photovoltaic panel 201 on its long side.

[0025] Specifically, the connecting seat 204 is provided with a photovoltaic panel 201 position adjustment component. The adjustment component includes a top rod 205, the upper end of which is hinged to the lower surface of the connecting seat 204, and the other end of which is hinged to a connecting block 207. The connecting block 207 is threadedly connected to a lead screw 206. The lead screw 206 is horizontally arranged inside the connecting seat 204 and is rotatably connected to the connecting seat 204.

[0026] Specifically, the adjustment assembly further includes a tilting assembly for tilting the photovoltaic panel 201 through the mounting bracket 101. The tilting assembly includes a lead screw 206 and a transmission assembly. The end of the lead screw 206 extends through the side of the connecting seat 204. The shaft of the bevel gear 301 is fixedly connected to the end of the lead screw 206, and a bevel gear B302 is meshed below the bevel gear 301. A shaft 303 is fixedly connected to the shaft of the bevel gear B302, and the upper end face of the shaft 303 is fixedly connected to the connecting seat 204. The transmission assembly is used to make the photovoltaic panel 201 rotate horizontally during the tilting process.

[0027] Specifically, the transmission assembly includes a transmission gear 304, the upper end face of which is fixedly connected to the lower end face of the shaft 303, and the transmission gear 304 is coaxial with the shaft 303. The transmission gear 304 is meshed with a gear ring 305, and the gear ring 305 is fixedly connected to the inner wall of the bottom cylinder 209.

[0028] In the above embodiment, the user starts the motor connected to the lead screw 206, causing it to rotate at a constant speed. At this time, the threaded connecting block 207 begins to move linearly along its sliding connection with the mounting bracket 101. Simultaneously, the push rod 205, under the action of the connecting block 207, begins to lift the connecting seat 204 upwards. The connecting seat 204 then begins to rotate upwards with its connection point with the connecting plate 203 as the fulcrum, gradually tilting the photovoltaic panel 201. Simultaneously, during the rotation of the lead screw 206, the bevel gear 301 fixedly connected to it... The photovoltaic panel 201 rotates step by step, that is, at this time the bevel gear 301 starts to drive the bevel gear B302 that meshes with it, so that the bevel gear B302 starts to drive the shaft 303 fixedly connected at its axis to rotate at a constant speed, so that the transmission gear 304 fixedly connected at its lower end face starts to roll on the gear ring 305 that meshes with it, that is, at this time the connecting plate 203 starts to rotate horizontally, so that the photovoltaic panel 201 rotates while adjusting its tilt, until the long side of the photovoltaic panel 201 is parallel to the long side of the mounting frame 101, at which point the tilt of the photovoltaic panel 201 is 70°.

[0029] Specifically, the base 202 is provided with a limiting component to prevent the photovoltaic panel 201 from sliding. The limiting component includes a stop rod 401 and an anti-slip component. The two stop rods 401 are symmetrically arranged on both sides of the long side of the photovoltaic panel 201. A rubber cylinder 402 is rotatably provided on the outer wall of the stop rod 401. The stop rod 401 and the rubber cylinder 402 are coaxial. The lower end face of the stop rod 401 is rotatably connected to the upper surface of the guide rod 309. The two guide rods 309 are horizontally arranged in the base 202. The anti-slip component is used to prevent the photovoltaic panel 201 from sliding on the support rod 401.

[0030] Specifically, electric push rods 308 are horizontally arranged on the ends of the two guide rods 309 inside the base 202, and the output shaft of the electric push rod 308 is fixedly connected to the corresponding guide rod 309. The two electric push rods 308 are fixedly connected to both sides of the connecting block 307, which is horizontally arranged in the base 202.

[0031] Specifically, the connecting block 307 is fixedly connected to the output shaft of the motor 306, and the lower end face of the motor 306 is fixedly connected to the inner bottom face of the base 202.

[0032] Specifically, the anti-slip component includes a semi-circular disk 403, which is fixedly connected to the upper end face of the abutment rod 401. The lower surface of the semi-circular disk 403 can be tightly attached to the upper surface of the photovoltaic panel 201 during rotation. The abutment rod 401 is rotatably mounted on the guide rod 309, and the lower end face of the abutment rod 401 extends through the lower end face of the guide rod 309.

[0033] Specifically, the lower end face of the abutment rod 401 is connected to a belt 407, the other side of the belt 407 is connected to a short rod 404, and the upper end face of the short rod 404 is rotatably connected to the guide rod 309.

[0034] Specifically, a gear 405 is fixedly connected to the lower end face of the short rod 404. The gear 405 meshes with the gear ring A406 during rotation, and the gear ring A406 is fixedly connected to the base 202.

[0035] In the above embodiment, before rotating the lead screw 206, the user should start the electric push rod 308, so that its output shaft begins to push the corresponding guide rod 309, thereby gradually increasing the distance between the abutment rod 401 rotatably connected to the guide rod 309 and the long side of the photovoltaic panel 201. The user can then start the motor 306, so that the connecting block 307 fixedly connected to its output shaft begins to rotate. At this time, the abutment rod 401 begins to gradually move towards the short side of the photovoltaic panel 201. When the two abutment rods 401 are respectively on both sides of the short side of the photovoltaic panel 201, the electric push rod 308 can then be started in the opposite direction, so that the two guide rods 309 move towards each other. During this process, the gear 405 gradually slides onto the gear ring A406, and the rubber sleeve 402 is then pressed tightly against the short side of the photovoltaic panel 201. That is, as the guide rod 309 continues to rotate, the rubber sleeve 402 can be pressed tightly against the short side of the photovoltaic panel 201, so that the rubber sleeve 402 is compressed to be pressed tightly against the photovoltaic panel 201. The short side of plate 201 is used to position and protect the photovoltaic panel 201. As 409 continues to rotate, gear 405 rolls on gear ring A406, causing the push rod 401 to rotate at a constant speed with the help of belt 407. At this time, the semi-circular disk 403 fixedly connected to its top begins to rotate to the upper surface of the photovoltaic panel 201. That is, the lower surface of the semi-circular disk 403 gradually presses against the upper surface of the photovoltaic panel 201. At this time, the rubber sleeve 402 and the semi-circular disk 403 are in contact... The two rods cooperate to provide bidirectional limiting for the photovoltaic panel 201, thereby preventing the photovoltaic panel 201 from sliding along the base 202 after it rotates and tilts. This effectively prevents the short side of the photovoltaic panel 201 from hitting the ground. At the same time, after the photovoltaic panel 201 is reset to the point where its long side is parallel to the short side of the mounting frame 101, the two abutment rods 401 are positioned on both sides of the long side of the photovoltaic panel 201, thus preventing the short side of the photovoltaic panel 201 from being stuck on the long side of the mounting frame 101 after it descends.
