Description

Technical Field

[0001] This utility model relates to a lifting frame, specifically a photovoltaic panel mounting lifting frame. Background Technology

[0002] In recent years, solar photovoltaic (PV) power generation technology has developed rapidly, providing clean energy for humanity by utilizing solar energy resources, and the application range of solar PV panels is becoming increasingly wide. To improve light-gathering efficiency and avoid shading from other structures, solar PV panels are generally installed on elevated locations using mounting brackets to maximize the area receiving sunlight. During installation, the PV panels must first be lifted to the height of the mounting brackets before being fixed in place. Most existing methods for lifting PV panels are manual, where workers raise the panels from their ground position to the height of the mounting brackets. This method is suitable for installing small batches of PV panels, but becomes labor-intensive when installing large quantities.

[0003] Currently, in the mass installation of photovoltaic panels, a winch can be used to lift the panels by pulling ropes. The panels are first secured and then pulled. While this method can replace manual labor to some extent, the process of securing, lifting, and then unsecured the panels is cumbersome. Furthermore, uneven stress on the frame during lifting can cause the panels to tip over or fall, damaging them. In addition, winches have specific site requirements. All of these methods have significant limitations in practical operation. Utility Model Content

[0004] To address the aforementioned shortcomings in the existing technology, this utility model aims to provide a photovoltaic panel installation lifting frame that can smoothly lift photovoltaic panels during installation and construction, reducing the labor intensity of workers and improving operational safety.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A photovoltaic panel mounting and lifting frame includes a frame and a lifting mechanism. The lifting mechanism is fixed inside the frame and includes a lifting plate, a lifting seat, a lifting motor, and a controller. The lifting plate is vertically fixed inside the frame, and a vertical rack is fixed on one side of the lifting plate. The lifting seat is movably sleeved on the lifting plate. A lifting motor and a placement plate for placing photovoltaic panels are fixed on the lifting seat. The output end of the lifting motor is connected to a gear that meshes with the rack. The lifting motor and the controller are connected by a signal. A clamping mechanism for clamping and fixing the photovoltaic panels is fixed on the placement plate.

[0006] As a limitation of this utility model: the clamping mechanism includes a bidirectional lead screw and a clamping plate. The two ends of the bidirectional lead screw are provided with a left slider and a right slider that are threadedly engaged with it. The left slider and the right slider are respectively fixed with clamping plates for clamping both sides of the photovoltaic panel, which are arranged parallel to the placement plate and perpendicular to the bidirectional lead screw. The placement plate is provided with a guide groove parallel to the bidirectional lead screw. The clamping plate is fixed with a guide block that matches the guide groove and is slidably placed in the guide groove.

[0007] As a limitation of this utility model: the clamping plate has clamping grooves on the side facing the photovoltaic panel for fixing the two sides of the photovoltaic panel.

[0008] As a limitation of this utility model: the clamping mechanism also includes a clamping control motor that can drive the bidirectional lead screw to rotate, and the clamping control motor is connected to the controller via a signal connection.

[0009] As a limitation of this utility model, the angle between the placement plate and the horizontal plane is in the range of 45° to 90°.

[0010] As a limitation of this utility model: a guide rod is fixed inside the frame for guiding and limiting the up and down movement of the lifting seat. The guide rod is vertically fixed on one or both sides of the lifting plate along the movement direction of the lifting seat. The guide rod passes through the lifting seat and slides with the lifting seat.

[0011] As a limitation of this utility model, it also includes a locking mechanism for fixing the frame to the ground. The locking mechanism includes a locking plate and a locking rod. A vertical shaft fixed to the frame is provided at the lower end of the lifting plate. The center of the locking plate is rotatably connected to the vertical shaft. Through holes are opened at both ends of the locking plate. The locking rod is movably disposed in the through holes. When the locking plate rotates to the point where the through holes are located at the outer edge of the bottom of the frame, the locking rod abuts against the two outer edges of the frame. The distance between the through holes at both ends is greater than the width of the bottom of the frame.

[0012] As a limitation of this utility model: the locking plate includes two plates stacked one on top of the other.

[0013] As a limitation of this utility model: the bottom of the frame is provided with casters for the overall movement of the frame, and the casters are provided with wheel locking devices, and there are 4 casters.

[0014] By adopting the above technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows:

[0015] (1) This utility model uses gear and rack meshing transmission to lift the photovoltaic panel. The photovoltaic panel is lifted smoothly by using the placement plate, which improves the safety of the operation process and can save manpower and reduce the labor intensity of workers in large-scale installation.

[0016] (2) The clamping mechanism of this utility model adopts a bidirectional screw structure. On the one hand, it can effectively and stably clamp the photovoltaic panel to avoid damage to the photovoltaic panel during the lifting process. On the other hand, the distance between the two clamping plates can be adjusted by the bidirectional screw to achieve the purpose of placing photovoltaic panels of different specifications. The clamping grooves on the clamping plates can further effectively fix the two sides of the photovoltaic panel, and the width of the clamping grooves can be increased to achieve the purpose of placing multiple photovoltaic panels. Under the premise that the photovoltaic panel is effectively clamped by the clamping mechanism, the placement plate can be set to an inclined state to save space occupied by the device and meet the needs of different construction occasions.

[0017] (3) The present invention is also provided with a guide rod, which is inserted through the lifting seat and slides with the lifting seat to guide and limit the up and down movement of the lifting seat, so as to make the lifting process of the lifting seat more stable and further protect the photovoltaic panel.

[0018] (4) The universal wheels of this utility model can realize the movement of the entire frame. When it is moved to the working position, the locking mechanism effectively locks the entire device to the ground to prevent the device from tipping over or tilting. The locking device of the universal wheels further improves the stability of the device during use.

[0019] In summary, this utility model has a simple structure, can smoothly lift photovoltaic panels, improves installation efficiency and construction safety, and is suitable for photovoltaic panel installation projects. Attached Figure Description

[0024] The preferred embodiments of this utility model are described below with reference to the accompanying drawings. It should be understood that the photovoltaic panel mounting frame described herein is a preferred embodiment and is only used for illustration and explanation of this utility model, and does not constitute a limitation thereof.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component must have a specific orientation, or that it must be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the content protected by this utility model. Example

[0026] This implementation example Figure 1 , Figure 2 As shown, a photovoltaic panel installation lifting frame includes a frame 1 and a lifting mechanism fixed within the frame 1, which lifts the position of the photovoltaic panel.

[0027] The lifting mechanism includes a lifting plate 2, a lifting seat 3, a lifting motor 4 and a controller (not shown in the figure). The lifting plate 2 is vertically fixed inside the frame 4, and its upper and lower ends are fixedly connected to the frame 1. A vertical rack 5 is fixed on the lifting plate 2.

[0028] The lifting seat 3 is movably mounted on the lifting plate 2. The lifting seat 3 moves up and down via a gear 7 mounted on it and meshing with the rack 5. Specifically, a lifting motor 4 is fixed to the lifting seat 3. The output end of the lifting motor 4 is connected to the gear 7 meshing with the rack 5. The lifting motor 4 is signal-connected to a controller. The controller and the lifting motor 4 drive the gear 7 to rotate, causing the lifting seat 3 to move up and down along the lifting plate 2. A placement plate 6 for placing photovoltaic panels is also fixed to the lifting seat 3. In this embodiment, the lifting seat 3 includes a portion on one side of the lifting plate 2 for fixing the placement plate 6, and a portion on the other side of the lifting plate 2 for fixing the lifting motor 4. By placing the lifting motor 4, rack 5, and gear 7 on the same side of the lifting plate 2, and the placement plate 6 on the other side, this partitioned structure with different functions facilitates installation, operation, and maintenance, while also enhancing the overall stability of the device.

[0029] To ensure greater stability of the lifting seat 3 during movement, guide rods 16 are fixed within the frame 1 to guide and limit the vertical movement of the lifting seat 3. The guide rods 16 are vertically fixed to one or both sides of the lifting plate 2 along the direction of movement of the lifting seat 3. In this embodiment, guide rods 16 are installed on both sides. Specifically, the guide rods 16 pass through both sides of the lifting seat 3 and slide in cooperation with it.

[0030] like Figure 1As shown, in order to effectively and stably place the photovoltaic panel, a clamping mechanism for holding and fixing the photovoltaic panel is fixed on the placement plate 6. Specifically, the clamping mechanism includes a bidirectional lead screw 8 and a clamping plate 11. The bidirectional lead screw 8 has a left slider 9 and a right slider 10 threadedly engaged at both ends. The left slider 9 and right slider 10 are respectively fixed with the clamping plate 11, which is parallel to the placement plate 6 and perpendicular to the bidirectional lead screw 8, for clamping both sides of the photovoltaic panel. The left slider 9 and right slider 10 should have a certain width on their opposite sides along the axial direction of the bidirectional lead screw 8, so that the left slider 9 and right slider 10 can abut against one edge of the photovoltaic panel placed in the clamping plate 11. The bidirectional lead screw 8 uses existing technology, utilizing the opposite rotation directions of its threads at both ends, to achieve simultaneous or dispersive movement of the left slider 9 and right slider 10 at its ends, thereby clamping or releasing the photovoltaic panel. Meanwhile, to restrict the two sliders from freely rotating with the lead screw and to ensure that the sliders can only translate along the axis of the lead screw, this embodiment includes a guiding constraint device. Specifically, a guide groove 13 parallel to the bidirectional lead screw 8 is provided on the placement plate 6, and a guide block 14 matching the guide groove 13 and slidably placed within the guide groove 13 is fixed on the clamping plate 11 at a corresponding position. The guide groove 13 and the guide block 14 limit the sliders and the clamping plate 11 to move towards or away from each other on a plane parallel to the plane of the placement plate 6 when the lead screw rotates. The rotation of the lead screw can be manually adjusted or automatically adjusted. Specifically, in this embodiment, a clamping control motor 15 is connected to one end of the bidirectional lead screw 8 to control the rotation of the bidirectional lead screw 8. The clamping control motor 15 is connected to the controller via a signal connection.

[0031] To more effectively secure the photovoltaic panel, a clamping groove 12 is formed on the side of the clamping plate 11 facing the photovoltaic panel. The clamping groove 12 is used to fix the two side edges of the photovoltaic panel, so that the left and right side edges of the photovoltaic panel are placed in the clamping groove 12. At the same time, the width of the clamping groove 12 can be set as needed to accommodate photovoltaic panels of different thicknesses, or when the width is large enough, it can also be used to clamp multiple photovoltaic panels placed on top of each other.

[0032] Provided that the photovoltaic panel is effectively clamped by the clamping mechanism, the placement plate 6 can be set to an inclined state. The inclined placement plate 6 can save space occupied by the device and meet the needs of different construction occasions. Specifically, the angle between the placement plate 6 and the horizontal plane is in the range of 45° to 90°, and the angle is 60° in this embodiment. When the placement plate 6 is inclined, the photovoltaic panel is also inclined. At this time, the side edge of the lower end of the photovoltaic panel abuts against the left slider 9 and the right slider 10, that is, the left slider 9 and the right slider 10 simultaneously generate a supporting force on the lower edge of the photovoltaic panel; the left and right ends of the photovoltaic panel are placed into the clamping groove 12, realizing the fixation of the position of the photovoltaic panel and the high clamping reliability.

[0033] To enable the frame 1 to move as a whole, several casters 20 are provided at the bottom of the frame 1. Each caster 20 is equipped with a wheel locking device (not shown in the figure). In this embodiment, four casters 20 are used. Both the casters 20 and their locking devices are implemented using existing technology. When the frame 1 is moved to the working position, the wheel locking devices can fix the casters 20, thereby fixing the position of the entire device. To further effectively lock the device to the ground and prevent the device from tipping or tilting during operation, in addition to the locking devices on the casters 20, this embodiment also provides a locking mechanism. Specifically, the locking mechanism includes a locking plate 17 and a locking rod (not shown in the figure). A section of vertical shaft 19, which is fixed to the frame 1, is fixed at the lower end of the lifting plate 2. The center of the locking plate 17 is rotatably connected to the vertical shaft 19. Both ends of the locking plate 17 have through holes 18 symmetrical about the center of the locking plate 17. The locking rod is movably disposed in the through holes 18. The distance between the through holes 18 at both ends of the locking rod should be greater than the width of the bottom of the frame. Rotate the locking plate 17 until the through hole 18 is located at the outer edge of the bottom of the frame. Insert the locking rod into the through hole 18 and drive it into the ground. The locking rod abuts against the two outer edges of the frame. Preferably, the locking plate 17 includes two plates stacked on top of each other. The two locking plates 17 can be arranged in a cross configuration to fix the frame 1 in four directions, thereby further improving the stability of the device during use.

[0034] The aforementioned lifting motor 4 and clamping control motor 15 are electrically connected to the power supply. For ease of construction, a mobile power supply (not shown in the figure) can be fixed on the frame 1, and the mobile power supply can be electrically connected to the lifting motor 4, clamping control motor 15, and controller.

[0035] The effective lifting height of this lifting frame can be set according to actual production needs. Specifically, different lifting heights can be achieved by setting the height of frame 1, the height of lifting plate 2, and the length of rack 5.

[0036] In using this embodiment, first place and fix the photovoltaic panel on the lifting base 3, move the device to the working position, open the locking device on the caster wheel 20, and effectively lock the device to the ground through the locking mechanism. Control the lifting base 3 to rise to a suitable position through the controller, remove the photovoltaic panel for installation. Then lower the lifting base 3 to a suitable position for placing the photovoltaic panel again.
