Technical Field

[0001] This invention relates to a photovoltaic panel installation device. Background Technology

[0002] Floating photovoltaic (PV) equipment refers to equipment that uses solar energy to generate electricity, installed and operated on the water surface. The advantages of floating PV equipment include making full use of water surface space, reducing land use, lowering water surface temperature, increasing water surface evaporation and reducing freshwater loss.

[0003] In the existing technology, when installing floating photovoltaic equipment, it is necessary to load a photovoltaic panel drive device to drive it to the installation position on the water, and then use the installation device on the drive device to lift and install the photovoltaic panel. However, since it is floating on the water, the installation device is affected by wind and waves, causing the equipment to sway. It takes a lot of time to adjust the installation position, which affects the installation efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a photovoltaic panel installation device to solve the aforementioned technical problems.

[0005] The above objectives are achieved through the following technical solutions: A photovoltaic panel installation device includes a clamping frame, which clamps and slides on a channel steel frame. The clamping frame is rotatably connected to a rotating support frame, which is used to lift and lower the photovoltaic panel. A clamping slide is connected to the rotating support frame, which is used to clamp the photovoltaic panel. An angle adjustment mechanism is connected to the clamping frame. The angle adjustment mechanism is used to adjust the angle of the inclined frame that pushes the rotating support frame to the rotating support frame. The angle adjustment mechanism is connected to the connecting shaft, which is used to drive the clamping slide to slide and flip.

[0006] The photovoltaic panel installation device includes a clamping frame comprising a portal frame, with a notch plate fixed at each end of the portal frame, two I-beam clamping wheels rotatably connected inside the notch plate, two wing plates fixed at the bottom of the notch plate, and two bottom clamping wheels rotatably connected between the two wing plates.

[0007] The photovoltaic panel installation device includes a rotating support frame comprising a bushing, with inclined frames fixed to both ends of the bushing, the bottom of the inclined frames being fixed to a base frame, the two base frames being fixed together by a tail plate, a crossbeam connecting the two inclined frames and the two base frames, and two longitudinal beams connecting the bushing to the crossbeam of the inclined frames.

[0008] The photovoltaic panel installation device includes an angle adjustment mechanism comprising a drive shaft, a drive screw, and a drive sleeve. A sliding sleeve is fixed on the drive shaft, and a splined inner shaft is fixed on the drive screw. The splined inner shaft is inserted into the sliding sleeve. The drive sleeve is fitted onto the drive screw and threadedly connected to it. Two support plates are fixed on the drive sleeve, and the support plates abut against the longitudinal beam.

[0009] The photovoltaic panel mounting device includes a drive shaft, an optical axis, and an adjusting screw. The end of the drive shaft is connected to the optical axis, and the optical axis is connected to the adjusting screw via a joint.

[0010] The photovoltaic panel mounting device includes a clamping slide table comprising a base plate, two grippers slidably connected to both sides of the base plate, a convex shaft slidably connected to the base plate and the grippers in a perpendicular direction, an adjusting plate fixed on the convex shaft, a support column on each gripper being inserted into the adjusting hole of the adjusting plate, and an adjusting sleeve fixed to the bottom of the base plate, the adjusting sleeve being fitted onto the adjusting screw sleeve of the adjusting screw.

[0013] In the photovoltaic panel installation device, the adjusting screw sleeve has limit rods fixed at both ends, and the limit rods are inserted into the limit slides of the corresponding side base frame.

[0014] In the photovoltaic panel installation device, the two ends of the drive screw sleeve are respectively fixed with support rods, and the support rods pass through the sliding holes on the corresponding side groove-shaped buckle plate. Beneficial effects

[0015] 1. This invention does not require electrical components; it only requires the cooperation of mechanical parts to achieve the clamping, lifting, and flipping of photovoltaic panels, thereby expanding the application range of the device.

[0016] 2. By clamping the device onto the photovoltaic support frame instead of placing it on the drive equipment, the present invention ensures that the installation of the photovoltaic panels is not affected by the instability of the water surface, thereby improving the installation efficiency.

[0017] 3. This invention features a linkage structure. When the adjusting screw is turned, the rotating support frame can be rotated to lift the photovoltaic panel. Simultaneously, when the adjusting screw is turned, the linkage clamping slide table causes the photovoltaic panel to slide and flip, enabling it to be smoothly lifted above the support and placed on the photovoltaic support according to the installation angle.

[0018] 4. This device can roll on the photovoltaic support, so when installing photovoltaic panels in different positions, you only need to roll the device to the required position, without having to re-clamp and install it. Attached Figure Description

[0020] Reference Figures 1-9 A photovoltaic panel installation device comprises a clamping frame 1, which clamps and slides on a channel steel frame 6. The clamping frame is rotatably connected to a rotating support frame 2, which is used to lift and lower the photovoltaic panel 5. A clamping slide 3 is connected to the rotating support frame, which is used to clamp the photovoltaic panel. An angle adjustment mechanism 4 is connected to the clamping frame. The angle adjustment mechanism is used to adjust the angle of the rotating support frame by the inclined frame 2.4 that pushes the rotating support frame. The angle adjustment mechanism is connected to the connecting shaft, which is used to drive the clamping slide to slide and flip.

[0021] When working, the device is first installed on the channel steel frame. The I-shaped clamping wheels and bottom clamping wheels on the clamping frame clamp the channel steel frame together, so that the device can slide on the channel steel frame to change the installation position. The operator activates the angle adjustment mechanism, which drives the rotating support frame to rotate. As the rotating support frame lowers, it simultaneously drives the clamping slide towards the tail plate side via a connecting shaft. Once the rotating support frame is in position, the clamping slide slides into place, at which point it is released. After placing the photovoltaic panel on the clamping slide, the operator reverses the adjustment screw, causing the rotating support frame to rotate in the opposite direction. During rotation, the clamping slide slides towards the inclined frame side, maintaining the clamping state. When the clamping slide reaches the middle position, the convex slide rail reverses the direction, causing the clamping slide to rotate at a certain angle. At this point, the operator presses... Rotate the support frame at the flipped angle to continue rotating and lifting, allowing the photovoltaic panel to move smoothly through the photovoltaic bracket and onto the top of the photovoltaic bracket. Then, flip it back to the initial angle via the clamping slide. After the support frame has moved into position, turn the adjusting screw in the opposite direction to lower the support frame. When the photovoltaic panel is about to contact the channel steel frame, do not turn the adjusting screw. The sliding device will slide the photovoltaic panel to the accurate installation position. Continue turning the drive screw to release the clamping slide from the photovoltaic panel. At this point, the support frame continues to lower, allowing the photovoltaic panel to fall onto the channel steel frame, thus achieving the initial installation of the photovoltaic panel. Then, personnel can install the clips to complete the installation.

[0022] The clamping frame includes a portal frame 1.2, with a notch plate 1.1 fixed at both ends of the portal frame. Two I-shaped clamping wheels 1.4 are rotatably connected inside the notch plate. Two wing plates 1.6 are fixed at the bottom of the notch plate. Two bottom clamping wheels 1.5 are rotatably connected between the two wing plates. The bottom pulleys and I-shaped clamping wheels clamp the channel steel plate together, allowing the device to slide on the channel steel plate. A fixed shaft 2.7 is also fixed on the portal frame.

[0023] The rotating support frame includes a bushing 2.6, which is sleeved on a fixed shaft and rotatably connected. Two inclined frames 2.4 are fixed to both ends of the bushing. The bottom of the inclined frame is fixed to the base frame 2.5. The two base frames are fixed together by a tail plate 2.9. A crossbeam is connected between the two inclined frames and between the two base frames. Two longitudinal beams 2.1 are connected between the bushing and the crossbeam of the inclined frame. Two parallel inclined frame crossbeams 2.3 are connected between the two inclined frames. A base frame crossbeam 2.10 is connected between the two base frames. The base frame is a square box 2.5.11 structure, which is a hollow box. An arc-shaped support surface 2.5.10 is fixed in the middle of the inner side of the square box. Then, a convex opening 2.5.1 is opened on the inner side of the square box. A convex platform is fixed at the convex opening, so that the convex opening and the convex platform together form a convex slide. The convex slide is a ring slide, including the upper slide 2.5.4, the upper middle flip slide 2.5.9, and the deflection slide 2.5.8 connecting the upper slide and the lower slide 2.5.12. Trapezoidal blocks are slidably connected to the inner sides of the directional slides from the upper slideway to the lower slideway and from the lower slideway to the upper slideway, respectively. The upper trapezoidal block is connected to the directional slideway from the lower slideway to the upper slideway. This upper trapezoidal block is inserted into the inner groove 2.5.5 on the side of the directional slideway, and a support spring is connected inside the inner groove. The inclined surface of the upper trapezoidal block faces downwards. When the through rod slides upwards through this directional slideway, it pushes this upper trapezoidal block into the inner groove. After passing the upper trapezoidal block, the through rod moves into position. At this point, under the action of the support spring, the upper trapezoidal block slides out, thus limiting the movement of the through rod. To prevent it from falling into the changing slideway during the upper sliding process, the trapezoidal block in the changing slideway from the upper slideway to the lower slideway is the lower trapezoidal block. The lower trapezoidal block is also inserted into the inner groove and is also connected to a support spring. The inclined surface of the lower trapezoidal block faces upward. When the through rod falls from the changing slideway from the upper slideway to the lower slideway, it will push the lower trapezoidal block to slide into the inner groove, allowing the through rod to smoothly enter the lower slideway. After the through rod passes, under the action of the support spring, the lower trapezoidal block will move back to the initial position. This can block the through rod and prevent it from returning to the changing slideway during the movement in the lower slideway.

[0024] Meanwhile, to ensure that the clamping slide remains loose during the process from when the photovoltaic panel is about to contact the channel steel frame until the rotating support frame is lowered into place, inner notches 2.5.3 are provided at the lower slide and the turning slide from the lower slide to the upper slide. In the part of the convex slide without inner notches, the through rod is inserted into the convex slide, and the spherical column 3.8 on the through rod abuts against the surface of the convex slide. At this time, the pressure spring is in a compressed state, and all four jaws are in a clamping state. When the through rod passes through the part with inner notches, the through rod is inserted into the lower slide. Under the action of the pressure spring, the entire convex shaft will slide towards the base frame on the side with the convex slide until the spherical column contacts the surface of the convex slide. At this time, the pressure spring is in a natural state. At this time, due to the movement of the adjusting plate, the position of its support column in the adjusting hole changes, causing it to push the jaws to be in a loose state.

[0025] The photovoltaic panel installation device includes an angle adjustment mechanism comprising a drive shaft 4.1, a drive screw 4.6, and a drive sleeve 4.5. A sliding sleeve 4.2 is fixed on the drive shaft, and the sliding sleeve has a spline groove inside. A splined inner shaft 4.3 is fixed on the drive screw and inserted into the sliding sleeve. The drive sleeve is fitted onto the drive screw and threadedly connected to the drive screw. Two support plates 4.4 are fixed on the drive sleeve, and the support plates abut against the longitudinal beam.

[0026] The drive sleeve is fixed with support rods 4.8 at both ends. The support rods pass through the sliding holes 1.3.1 on the corresponding side slotted buckle plate 1.3. The support rods are cylindrical rods. The support rods and sliding holes limit the drive sleeve, preventing it from rotating when the drive screw is turned. The drive sleeve is in a sliding state. As the drive sleeve slides, the support plate on the drive sleeve abuts against the longitudinal beam, which pushes the rotating support frame to rotate, changing its angle. At the same time, the angle of the drive screw also changes when the rotating support frame rotates. The support rod of the drive sleeve is a cylindrical rod and is located in the sliding hole. The drive sleeve serves as a support for the rotation of the drive screw and a rotating sleeve. The drive coupling shaft is fixed with a sliding sleeve. The adjusting screw is fixed with a splined inner shaft, which is inserted into the sliding sleeve. The sliding sleeve has a splined groove, which forms a telescopic structure to compensate for the change in the length of the adjusting screw when the rotating support frame is turned.

[0027] The connecting shafts include a drive connecting shaft 4.1, an optical shaft 2.2, and an adjusting screw 3.16. The end of the drive connecting shaft is connected to the optical shaft, and the optical shaft is connected to the adjusting screw via joints 2.8. The joint between the drive connecting shaft and the optical shaft includes a concave plate, which is fixed to the end of the optical shaft. A horizontal shaft is fixed inside the concave plate, and the drive connecting shaft is sleeved on the horizontal shaft to achieve linkage. The joint between the optical shaft and the adjusting screw also includes a concave plate, which is fixed to the end of the adjusting screw. A horizontal shaft is fixed inside the concave plate, and the optical shaft is sleeved on the horizontal shaft to achieve linkage. This joint enables the drive connecting shaft, the optical shaft, and the adjusting screw to achieve linkage without affecting the change in the angle between the drive connecting shaft and the optical shaft when the adjusting screw is turned.

[0028] The clamping slide includes a base plate 3.4, with two grippers 3.6 slidably connected to both sides of the base plate. A convex shaft 3.10 is slidably connected to the base plate in the perpendicular direction to the grippers. The convex shaft slides in a convex shaft groove 3.1. Two adjusting plates 3.3 are fixed on the convex shaft. Each adjusting plate has two adjusting holes, which are arranged in a figure-eight shape. The support column 3.2 on each gripper is inserted into the adjusting hole 3.11 of the adjusting plate. An adjusting sleeve 3.13 is fixed to the bottom of the base plate and is fitted onto the adjusting screw sleeve 3.15 of the adjusting screw.

[0029] One end of the convex shaft is fitted with a pressure spring 3.9 and a connecting plate 3.12 is fixed thereon. A through rod 3.7 is fixed on the connecting plate. The through rod passes through the multi-position slide rail of the base frame on the corresponding side. The multi-position slide rail is a convex slide rail. The pressure spring is sleeved on the cam shaft on the side with the smaller gap between the two adjustment holes. When the pressure spring is in a compressed state, the support column is on the side with the smaller gap between the two adjustment holes, and the two jaws are in a clamping state. When the pressure spring returns to its natural state, the cam shaft slides on the side with the smaller gap between the two adjustment holes. After sliding, the support column will gradually slide towards the side with the larger gap in the adjustment hole, which will push the jaws to release it.

[0030] The adjusting screw sleeve is fixed with limit rods 3.14 at both ends. The limit rods are inserted into the limit slides 2.5.13 of the corresponding side base frame. The limit slides are horizontally arranged and can limit the adjusting screw sleeve to prevent the adjusting screw sleeve from rotating when the adjusting screw rotates.

[0031] Working principle: When using it, refer to... Figure 10First, the device is installed on the channel steel frame 6. The I-shaped clamping wheels and bottom clamping wheels on the clamping frame clamp the channel steel frame together, allowing the device to slide on the channel steel frame to change its installation position. First, slide the device between the two column supports of the photovoltaic panel. This will not interfere with the movement of the rotating support frame of the device. Then, the personnel on the channel steel frame of the photovoltaic panel hold the fixing nut 4.7 on the adjusting screw and rotate the adjusting screw to make the adjusting screw sleeve slide, for example, slide to the left. At this time, the rotating support frame rotates gradually under its own weight, with the longitudinal beam always in contact with the support plate of the adjusting screw sleeve, so as to lower it. When the longitudinal beam contacts the upper horizontal plate of the channel-shaped buckle plate, it indicates that it has been lowered into place. During the downward movement, the mandrel is positioned within the lower slideway. Since the lower slideway has an inner notch after changing direction from the upper slideway to the lower slideway, the pressure spring, under its own action, keeps it in its natural state. The spherical column rests against the surface of the lower slideway, and the gripper is in a released state. When the mandrel moves to the changing slideway after passing the lower slideway and changing direction from the upper slideway, the inclined surface of the upper trapezoidal block within this changing slideway faces downwards. Thus, as the mandrel slides upwards within this changing slideway, it pushes this upper trapezoidal block into the inner groove. After passing the upper trapezoidal block, the mandrel moves into position, and the rotating support frame also lowers into position. At this point, under the action of the support spring, the upper trapezoidal block slides out, allowing the mandrel to pass through... The core rod is limited to prevent it from falling into the changing slide track during the upper sliding process. At this time, the gripper is in the released state. The photovoltaic panel is placed on the base plate, and the four protrusions 3.5 on the base plate will contact the bottom of the photovoltaic panel. The protrusions have rubber blocks 3.17. The rubber blocks are hard rubber blocks, which can increase the friction between the photovoltaic panel and the protrusions and ensure the stability of the photovoltaic panel after clamping. After the photovoltaic panel 5 is placed on the clamping slide, the adjusting screw is rotated in the opposite direction to make the adjusting screw sleeve slide. The rotating support frame is supported to make it rotate and gradually rise. During the rise, the core rod is in the changing slide track from the lower slide track to the upper slide track, and then slides in the upper slide track. During the sliding process, the core rod is in the changing slide track from the lower slide track to the upper slide track. When the spherical column moves to the part without the inner notch, it contacts the surface of the upper slide rail, pressing the convex shaft to rotate, causing the adjusting plate to move. This causes the support column to move towards the side with the smaller gap between the two adjusting holes within the adjusting hole, which drives the claw clamp to hold the photovoltaic panel. The clamped state is maintained, and the drive screw continues to rotate. Due to the linkage of the shaft, the adjusting screw continues to rotate. The adjusting screw is threadedly connected to the adjusting screw sleeve, and limit rods are fixed at both ends of the adjusting screw sleeve. These limit rods prevent the adjusting screw sleeve from rotating along with the adjusting screw. This causes the clamping slide to slide towards the inclined frame side. During the sliding, when the through rod passes through the flipping slide rail, there is an arc-shaped support surface 2.5 at the flipping slide rail.10. This arc-shaped support surface is designed to accommodate changes in the rotation angle of the clamping slide. Its curvature matches the rotation angle of the clamping slide, ensuring the pressure spring remains compressed and the grippers maintain their clamping position. The base frame without the convex slide groove is a square rod structure with a limit track. This square rod structure allows the entire clamping slide to rotate and rotate at a certain angle when the through rod slides to the rotation track. At this point, the clamping slide on the square rod side rotates downwards, while the side with the convex slide groove rotates upwards. This square rod design does not affect the rotation of the clamping slide or the rotation of the photovoltaic panel. After passing through the rotation track, the photovoltaic panel has been lifted to the upper part of the channel steel frame. The through rod sliding into the upper slide groove causes the clamping slide to rotate back to its original position, allowing the photovoltaic panel to rotate back. When the upper part of the inclined frame of the rotating support frame contacts the top of the clamping groove frame, it indicates that the lifting is complete, and the through rod is in the upper slide groove or lower slide groove. At the deflection slide, the entire clamping slide will fall under its own weight. The through rod falls within the deflection slide, passes the lower trapezoidal block, pushes the lower trapezoidal block into the inner groove, and then falls into the lower slide. At this point, the lower trapezoidal block slides out again under the action of the support spring, which can limit the through rod and prevent it from flipping into the deflection slide. Then, the drive screw is rotated in the opposite direction, causing the rotating support frame to gradually fall. When the photovoltaic panel is about to contact the channel steel frame (observed by personnel), the drive screw is stopped, and the entire device is pushed to the position where the photovoltaic panel needs to be installed. The drive screw is continued to be turned, and the through rod slides to the position with the lower slide and the inner cut. Under the action of the pressure spring, the clamps are released. At this time, the rotating support frame continues to fall, allowing the photovoltaic panel to land on the channel steel frame, achieving the initial installation of the photovoltaic panel. Then, the personnel install the clips to complete the installation. Then, the above operation is repeated to allow the rotating support frame to continue falling down for the installation of the next photovoltaic panel.
