Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation technology, and in particular to a photovoltaic panel fixing and disassembly device. Background Technology

[0002] In photovoltaic (PV) power generation projects, PV panels are often installed on open ground, rooftops, and aerial platforms using brackets. In existing technologies, PV panels are mostly fixed to the brackets by tightening bolts sequentially, resulting in low efficiency during installation and disassembly. To address this issue, Chinese invention patent CN119561473A discloses a photovoltaic panel fixing device that facilitates installation and disassembly. This device connects to the PV bracket via a fixed frame. After the movable frame is switched to the installation position (extending from the fixed frame at the top), the PV panel is placed inside. The movable frame is then pushed towards the support ring, causing the fixing element to rotate under the action of the fixed frame and clamp the PV panel with the installation ring. Finally, a limiting rod locks the movable frame in place, completing the fixing process. Disassembly simply requires releasing the limiting rod and moving the movable frame to remove the PV panel, significantly improving operational convenience.

[0003] However, the aforementioned patents still have technical shortcomings in practical applications: mainstream photovoltaic panels weigh between 15-30 kg, and to ensure light-gathering efficiency, the mounting frame needs to be installed at an angle on the support. When installing photovoltaic panels, technicians typically place the bottom of the panel at the bottom of the mounting cavity, then slowly move the top towards the top of the cavity. However, during this process, the panel's own weight exerts downward pressure on the movable frame, easily driving it towards the support ring; this movement causes the fixing component to rotate inward, directly blocking the top of the panel from smoothly entering the mounting cavity. The current common solution is to deliberately keep the photovoltaic panel parallel to the support ring during installation to avoid interference from the fixing component, but this requires technicians to continuously lift the heavy panel to maintain balance, which is not only time-consuming and laborious but also increases safety hazards during installation. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a photovoltaic panel fixing and disassembly device to solve the technical problems of easy movement of the movable frame and interference of the fixing parts during photovoltaic panel installation.

[0005] To achieve the above objectives, the present invention provides a photovoltaic panel fixing and disassembly device, comprising: A fixed frame has an inner cavity. A support ring is provided at the bottom of the inner side of the first side plate of the fixed frame. Several first limiting springs are arranged at intervals along the circumferential direction on the upper end surface of the support ring. The movable frame is slidably assembled in the accommodating cavity, and its inner side forms an installation cavity for placing photovoltaic panels. The inner side of the second side plate of the movable frame is provided with an installation ring. A plurality of first blocks and a plurality of second blocks are spaced apart along the circumference on the inner side of the second side plate. The first blocks are located above the second blocks. The installation ring is slidably limited between the first blocks and the second blocks, and the bottom of the second side plate abuts against the top of the first limiting spring. A limiting component is used to lock and fix the fixing frame and the second side plate; A clamping element is used to clamp the mounting ring onto the first stop block.

[0006] Furthermore, the clamping members are provided in multiple quantities, and the multiple clamping members are distributed circumferentially at intervals on the support ring; the clamping members include: A threaded tube is vertically installed on the lower end face of the support ring; The screw is threaded to the threaded pipe, its top end passes through the support ring and abuts against the mounting ring, and its bottom end extends to the outside of the threaded pipe.

[0007] Furthermore, the clamping member also includes: The top plate is installed at the top of the screw and contacts and engages with the lower end face of the mounting ring; The second limiting spring is sleeved on the screw, with its top end fixedly connected to the lower end face of the top plate and its bottom end fixedly connected to the upper end face of the support ring.

[0008] Furthermore, the fixed frame is provided with limiting members at its opposite ends, and the limiting members include: The first limiting plate is fixedly installed on the outer side of the first side plate; The limiting bolt is vertically installed on the upper end face of the first limiting plate; The second limiting plate is fixedly installed on the outer side of the second side plate and has a limiting through hole for the limiting bolt to pass through. The limiting nut is used when the first limiting plate contacts the second limiting plate, the limiting bolt passes through the limiting through hole, and the limiting nut is threadedly connected to the exposed part of the limiting bolt.

[0009] Furthermore, the clamping member also includes: The handle is fixedly mounted on the bottom end of the screw.

[0010] Furthermore, the photovoltaic panel fixing and disassembly device also includes: The fixing component is rotatably mounted on the upper surface of the second side plate via a rotating component; one side of the fixing component contacts and engages with the top of the first side plate, and the other side contacts and engages with the photovoltaic panel, and is arranged in a stepped shape.

[0011] Furthermore, the rotating component is a rotating shaft, which is rotatably mounted on the top of the second side plate, and the fixing component is fixedly connected to the rotating shaft.

[0012] Furthermore, a torsion spring is fitted onto the rotating shaft, and the torsion spring is used to drive the fixing member to rotate away from the mounting cavity.

[0013] Furthermore, the support ring extends toward the accommodating cavity to form an auxiliary plate, and the threaded tube portion is mounted on the lower end face of the auxiliary plate.

[0014] The beneficial effects of this invention are: When the movable frame is in the installation position, part of the movable frame is outside the receiving cavity, and the installation cavity is unobstructed, providing ample operating space for placing the photovoltaic panel. By operating the clamping device, the installation ring is clamped onto the first stop block. At this time, during the process of placing the photovoltaic panel into the installation cavity, the movable frame will not move towards the support ring under the gravity of the photovoltaic panel, and the fixing device will not rotate. This effectively avoids interference of the fixing device with the installation of the photovoltaic panel. The operator does not need to continuously lift the heavy photovoltaic panel and maintain stability, saving time and effort and eliminating safety hazards during the installation process.

[0023] This invention provides a photovoltaic panel fixing and disassembly device, comprising: a fixing frame 1, the inner side of which forms a receiving cavity 11, a support ring 12 provided at the bottom of the inner side of the first side plate 14 of the fixing frame 1, and a plurality of first limiting springs 13 spaced apart along the circumferential direction on the upper end surface of the support ring 12; a movable frame 2, slidably assembled in the receiving cavity 11, the inner side of which forms an mounting cavity 21 for placing the photovoltaic panel, a mounting ring 22 provided on the inner side of the second side plate 25 of the movable frame 2, a plurality of first blocks 23 and a plurality of second blocks 24 spaced apart along the circumferential direction on the inner side of the second side plate 25, the first blocks 23 being located above the second blocks 24, the mounting ring 22 being slidably limited between the first blocks 23 and the second blocks 24, and the bottom of the second side plate 25 abutting against the top of the first limiting springs 13; a limiting member 4 for locking and fixing the fixing frame 1 and the second side plate 25; and a pressing member 5 for pressing the mounting ring 22 against the first blocks 23.

[0024] In the technical solution proposed in this application, when the movable frame 2 is in the installation position, part of the movable frame 2 is located outside the accommodating cavity 11, and the installation cavity 21 is unobstructed, providing sufficient operating space for the photovoltaic panel to be placed. When the clamping member 5 is operated, the installation ring 22 is clamped onto the first stop block 23. At this time, during the process of placing the photovoltaic panel into the installation cavity 21, the movable frame 2 will not move towards the support ring 12 under the gravity drive of the photovoltaic panel, and the fixing member 3 will not rotate, effectively avoiding interference of the fixing member 3 with the installation of the photovoltaic panel. The operator does not need to continuously lift the heavy photovoltaic panel and maintain stability, saving time and effort and eliminating safety hazards in the installation process.

[0025] Regarding the specific structure of the clamping member 5, as a preferred embodiment, a further improvement of the present invention is that four clamping members 5 are provided, and the four clamping members 5 are distributed circumferentially at intervals on the support ring 12. The clamping member 5 includes: a threaded tube 51, which is vertically installed on the lower end face of the support ring 12; a screw 52, ​​which is threadedly connected to the threaded tube 51, with its top end penetrating through the support ring 12 and abutting against the mounting ring 22, and its bottom end extending to the outside of the threaded tube 51; the clamping member 5 also includes: a top plate 55, which is installed on the top end of the screw 52 and contacts the lower end face of the mounting ring 22; a second limiting spring 54, which is sleeved on the screw 52, ​​with its top end fixedly connected to the lower end face of the top plate 55 and its bottom end fixedly connected to the upper end face of the support ring 12; the clamping member 5 also includes: a handle 53, which is fixedly installed on the bottom end of the screw 52. In a specific embodiment, the top plate 55 is made of an elastic material to ensure that elastic compression can be achieved between the top plate 55 and the mounting ring 22.

[0026] It is worth noting that when the screw 52 is threadedly connected to the threaded tube 51, the two cannot achieve a strict locking. This invention solves this problem by setting a second limiting spring 54 and sleeved on the screw 52. The top end of the second limiting spring 54 is fixedly connected to the lower end face of the top plate 55, and the bottom end is fixedly connected to the upper end face of the support ring 12. When the screw 52 moves to the top end and the operator stops operating the handle 53, the screw 52 can move or tilt slightly within the threaded tube 51 under the pulling force of the second limiting spring 54, thereby achieving self-locking between the screw 52 and the threaded tube 51, and thus clamping the photovoltaic panel more firmly. When the screw 52 moves to the bottom end and the operator stops operating the handle 53, the screw 52 can move or tilt slightly within the threaded tube 51 under the pushing force of the second limiting spring 54, similarly achieving self-locking between the screw 52 and the threaded tube 51.

[0027] Regarding the installation position and specific structure of the limiting member 4, as a preferred embodiment, the present invention further improves in that limiting members 4 are respectively provided at opposite ends of the fixing frame 1. The limiting member 4 includes: a first limiting plate 41, fixedly installed on the outer side of the first side plate 14; a limiting bolt 42, vertically installed on the upper end face of the first limiting plate 41; a second limiting plate 43, fixedly installed on the outer side of the second side plate 25, and having a limiting through hole 45 for the limiting bolt 42 to pass through; a limiting nut 46, when the first limiting plate 41 and the second limiting plate 43 are in contact, the limiting bolt 42 passes through the limiting through hole 45, and the limiting nut 46 is threadedly connected to the exposed part of the limiting bolt 42. The second limiting plate 43 is provided with a handle (44) for convenient operation by the operator.

[0028] Regarding the specific structure of the fixing member 3, as a preferred embodiment, a further improvement of the present invention is that the photovoltaic panel fixing and disassembly device further includes: a fixing member 3, rotatably mounted on the upper end surface of the second side plate 25 via a rotating member 31; one side of the fixing member 3 contacts and engages with the top end of the first side plate 14, and the other side contacts and engages with the photovoltaic panel, and is arranged in a stepped shape. The rotating member 31 is a rotating shaft, which is rotatably mounted on the top end of the second side plate 25, and the fixing member 3 is fixedly connected to the rotating shaft. A torsion spring is sleeved on the rotating shaft, and the torsion spring is used to drive the fixing member 3 to rotate away from the mounting cavity 21.

[0029] It should be noted that the rotating shaft and torsion spring are both commonly used structures in the prior art, and their role in this invention patent can be referred to the comparative literature mentioned in the background art.

[0030] To prevent the support ring 12 from being too wide, which would prevent it from failing to provide adequate support, as a preferred embodiment, the present invention further improves by having the support ring 12 extend toward the accommodating cavity 11 to form an auxiliary plate 121, with the threaded tube 51 partially mounted on the lower end face of the auxiliary plate 121.

[0031] The specific operation process of this invention is as follows: The movable frame 2 is in the installation position: In the initial state, the bottom perimeter of the second side plate 25 of the movable frame 2 is in the installation position away from the support ring 12 on the fixed frame 1 under the force of the first limiting spring 13. It is worth noting that under the limiting action of the second stop 24, the mounting ring 22 will not contact the first limiting spring 13. At this time, the fixing member 3 and part of the movable frame 2 are located outside the accommodating cavity 11, and the mounting cavity 21 is unobstructed, providing sufficient operating space for the photovoltaic panel to be placed. The operator manually rotates the handle 53. Driven by the handle 53, the screw 52 moves upward along the threaded tube 51. The screw 52 synchronously drives the top plate 55 to move upward. The top plate 55 further drives the mounting ring 22 to rise until the first stop 23, the mounting ring 22 and the top plate 55 are in close contact in sequence. At this time, during the process of placing the photovoltaic panel into the mounting cavity 21, the movable frame 2 will not move towards the support ring 12 under the gravity of the photovoltaic panel, and the fixing part 3 will not rotate, effectively avoiding interference of the fixing part 3 with the installation of the photovoltaic panel. The operator does not need to continuously lift the heavy photovoltaic panel and maintain stability, saving time and effort and eliminating safety hazards in the installation process.

[0032] Moving the movable frame 2 to the fixed position: After placing the photovoltaic panel into the mounting cavity 21, the bottom of the photovoltaic panel contacts the mounting ring 22. The operator rotates the handle 53 in the opposite direction, and the screw 52 drives the top plate 55 to move downward until the top plate 55 is completely separated from the mounting ring 22 and no longer interferes with the movement of the mounting ring 22. Under the gravity of the photovoltaic panel, the four corners of the mounting ring 22 contact the second stop block 24 respectively, and the second side plate 25 of the movable frame 2 presses down on the first limit spring 13 for a certain distance and then stops. The operator holds the handle 44 and presses the second side plate 25 of the movable frame 2 towards the support ring 11. During the pressing process, the first limit spring 13 is further compressed and stored. When the movable frame 2 moves to the preset fixed position, the limit bolt 42 on the fixed frame 1 passes into the limit through hole 45. The limit nut 46 is tightened at the end of the limit bolt 42, and the second side plate 25 of the movable frame 2 is locked in the fixed position.

[0033] Fixing the photovoltaic panel with fastener 3: As the movable frame 2 moves towards the support ring 12, the top of the inner side of the fixed frame 1 contacts and engages with one side of the fastener 3. The squeezing force of the contact surface drives the fastener 3 to rotate around the rotating component 31 towards the mounting cavity 21 until the other side of the fastener 3 is in close contact with the surface of the photovoltaic panel. The operator then rotates the handle 53 again, causing the screw 52 to rotate upward. The screw 52 drives the top plate 55 to move upward, and the top plate 55 drives the mounting ring 22 to move upward. The mounting ring 22 simultaneously drives the photovoltaic panel to move towards the fastener 3. Finally, the mounting ring 22 and the fastener 3 work together to firmly clamp the photovoltaic panel, completing the fixed installation of the photovoltaic panel.

[0034] When disassembling photovoltaic panels, simply reverse the above steps to quickly complete the disassembly; the operation is convenient and efficient.

[0035] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
