Description

Technical Field

[0001] This utility model relates to the field of drone applications, and in particular to a drone hoisting device for photovoltaic modules. Background Technology

[0002] During installation, photovoltaic (PV) panels are typically transported from the base to the rooftop using cranes or tower cranes. This is a relatively mature and commonly used transportation method. However, the landing point of the PV panels is limited by the crane. With the application of drone technology, a technique has emerged in the field of using heavy-duty drones to lift and transport PV panels. Typically, the PV panels are secured to the drone with steel cables, and then the drone transports them to any location. Compared to traditional crane transportation, drone transportation expands the range of landing points and improves the efficiency of lifting and transportation. However, the connection between the steel cables and the PV panels is still the original method of winding and fixing, which wastes transportation time, and loose winding can easily lead to the PV panels falling during transportation. Therefore, this utility model proposes a device specifically for lifting PV panels. Utility Model Content

[0003] The purpose of this application is to provide a drone hoisting device for photovoltaic modules, which aims to solve the problems existing in the prior art.

[0004] This application provides a drone hoisting device for photovoltaic modules, including two opposing open frames. Slots are provided on the sides of each open frame opposite to the openings. Soft pads are fixedly connected to the sides of the two open frames adjacent to the slots. Connecting ears are installed at the open ends of the open frames, and the two open frames are connected via these connecting ears. An angle bracket is fixedly connected to the top of each open frame. The angle bracket is a right-angled triangle, with its right angle corresponding to the open end of the open frame. The two angle brackets are rotatably connected at their vertices, and a lifting point is fixedly connected to the axis of rotation. A drone is connected to the lifting point via a steel cable.

[0005] Furthermore, the drone is a transport drone.

[0006] Furthermore, the connecting lugs have through screw holes. Bolts are screwed into the connecting lugs on the same side of the two open frames, and the two open frames are connected by tightening nuts on the bolts.

[0007] Furthermore, the corner frame is divided into a type I corner frame and a type II corner frame. The top of the type II corner frame is fixedly connected to a crossbeam, which is in the shape of a round tube. A pivot is rotatably connected inside the crossbeam, and both ends of the pivot extend out of the crossbeam. The type I corner frame is fixedly connected to the pivot on the extended part.

[0008] Furthermore, the bottom of the type-1 corner frame is fixedly connected to the open frame via a horizontal liner, and the bottom of the type-1 corner frame coincides with the horizontal liner. There are two type-1 corner frames, and the two horizontal liner frames are connected via a longitudinal liner, which is fixedly connected to the open frame.

[0009] Furthermore, the bottom of the type II corner frame is fixedly connected to the open frame via a horizontal support frame, and the bottom of the type II corner frame partially overlaps with the horizontal support frame.

[0010] Furthermore, the middle of the corner frame is hollowed out.

[0011] The beneficial effects of this utility model are as follows: This utility model clamps the photovoltaic panel by setting two rotatable and openable frames to form a surrounding frame that can limit and protect the photovoltaic panel. The rotatable open frames enable quick installation and removal of the photovoltaic panel, thereby eliminating the need for the process of winding with steel cables, simplifying the procedure, and improving work efficiency.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1 The image shows a drone hoisting device for photovoltaic modules, comprising two opposing open frames 1, the open frames 1 as shown... Figure 2As shown, slots 2 are provided on the sides of the open frame 1 opposite to the opening. Soft pads 3 are fixedly connected to the sides of the two open frame 1 adjacent to the slots 2. The pads 3 can be made of silicone or rubber and are used to provide flexible support for the photovoltaic panel. The two open frames 1 enclose the photovoltaic panel, forming a protective frame for it. The two ends of the photovoltaic panel abut against the slots 2 of the two open frame 1, limiting the position of the photovoltaic panel and preventing it from falling during hoisting.

[0019] The open end of the open frame 1 is equipped with a connecting ear 4. The connecting ear 4 has a through screw hole. The bolt is screwed into the connecting ear 4 on the same side of the two open frames 1 and the nut on the bolt is tightened to make the two open frames 1 close together and be fixed.

[0020] Each of the opening frames 1 is fixedly connected to a corner bracket at its top. The corner bracket is a right-angled triangle with a hollow center to reduce the load on the drone. The right angle of the corner bracket corresponds to the opening end of the opening frame 1. The two corner brackets are rotatably connected at their vertices. The two opening frames 1 can rotate relative to each other through the two corner brackets, thereby opening the two opening frames 1 to release the clamped photovoltaic panels. A lifting point 5 is fixedly connected to the rotating shaft, and the drone is connected to the lifting point 5 by a steel cable. Preferably, the drone is a transport drone with a payload.

[0021] like Figure 1 and Figure 3 As shown, the corner brackets are divided into type I corner bracket 6 and type II corner bracket 7. Type I corner bracket 6 and type II corner bracket 7 have the same structure and shape. The top of type II corner bracket 7 is fixedly connected to a crossbeam 8. The crossbeam 8 is cylindrical, and a rotating shaft 9 is rotatably connected inside the crossbeam 8. Both ends of the rotating shaft 9 extend from the crossbeam 8, and the type I corner bracket 6 is fixedly connected to the rotating shaft 9 on the extended portion. There are two type I corner brackets and two type II corner brackets, each connected to either the rotating shaft 9 or both ends of the crossbeam 8. This results in the distance between two type I corner brackets 6 being greater than the distance between two type II corner brackets 7.

[0022] To compensate for the impact of different spacing on the opening frame 1, the bottom of a type I corner bracket 6 is fixedly connected to the opening frame 1 via a horizontal support frame 10, and the bottom of the type I corner bracket 6 coincides with the horizontal support frame 10. The two horizontal support frames 10 are connected by a longitudinal support frame 11, which is fixedly connected to the opening frame 1. The bottom of a type II corner bracket 7 is fixedly connected to the opening frame 1 via a horizontal support frame 10, and the bottom of the type II corner bracket 7 partially coincides with the horizontal support frame 10. The other part of the horizontal support frame 10 coincides with the opening frame 1, thus forming a stepped connection between the type II corner bracket 7 and the opening frame 1.

[0023] To ensure that slot 2 does not interfere with the photovoltaic panel during rotation, the thickness and depth of slot 2 need to be limited. For example... Figure 4As shown, the depth requirements are as follows: Using the pivot 9 as the center O(a, b) and the radius from the center to the lower point P(x, y) of slot 2, the standard formula for the circle can be obtained. Then, set the endpoint M(xm, ym) of the photovoltaic panel and any point N(xn, yn) on the circle. When ym equals yn, ensure that |xm| is less than |xn|. The thickness requirements are as follows: Keeping the circle unchanged, set the endpoint M(xm, ym) of the photovoltaic panel and any point N(xn, yn) on the circle. When xm equals xn, ensure that |ym| is less than |yn|.

[0024] In addition to the above requirements, a base column needs to be installed at the bottom of the photovoltaic panel during installation and removal. Precast cement columns used on-site for photovoltaic panel installation can be used. The purpose of the base column is to lift the photovoltaic panel in slot 2, bringing it closer to the top of slot 2, thereby further eliminating the interference effect of slot 2 on the photovoltaic panel during rotation.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
