Description

Technical Field

[0001] This utility model belongs to the field of flexible tracking bracket technology, specifically, it relates to a column drive structure in a flexible tracking bracket that is easy to replace. Background Technology

[0002] The existing photovoltaic system structure includes a photovoltaic panel module and an adjustable flexible support module. The photovoltaic panel module is mainly used to convert solar energy or light energy into electrical energy. The adjustable flexible support module is used to support the photovoltaic panel module and is mainly used to adjust the orientation of the photovoltaic panel module. It can be understood that the sun rises in the east and sets in the west relative to the earth periodically. In order to increase the power generation of the solar photovoltaic panel, the orientation of the photovoltaic panel module can be adjusted in real time to increase the power generation of the solar photovoltaic panel.

[0003] There are various types of existing adjustable flexible support components. For example, patent application number CN202510579140.7 discloses a flexible photovoltaic support and a flexible photovoltaic system. The flexible photovoltaic support includes a main cable assembly, a support structure, and a wind-resistant component. The support structure includes at least two components for anchoring the main cable assembly. The wind-resistant component includes a wind-resistant cable and a first wind-resistant frame. The two ends of the wind-resistant cable are respectively connected to the support structure, and the first side of the first wind-resistant frame is connected to the main cable assembly. The wind-resistant cable is connected to the first wind-resistant frame through a first vertical cable, so that the middle part of the wind-resistant cable arches upward, and the second side of the first wind-resistant frame arches towards the first side close to the first wind-resistant frame to form a clearance space for the arching of the wind-resistant cable.

[0004] The aforementioned existing flexible photovoltaic support uses a central rotating crossbeam to support the middle of the main cable assembly. A central support structure is provided below the central rotating crossbeam, and a central mounting frame is installed on the central support structure. A central drive device for driving the central rotating crossbeam to rotate is installed on the central mounting frame. The power output end of the central drive device is directly fixedly connected to the central rotating crossbeam. When the central drive device is activated, it drives the central rotating crossbeam to rotate, thereby adjusting the tilt angle of the main cable assembly.

[0005] Therefore, it is evident that the existing flexible photovoltaic support system lacks a rotational support between the central rotating beam and the central mounting frame. The gravity and traction forces acting on the central rotating beam are transferred to the central drive unit, causing severe stress on the drive unit and significantly impacting its lifespan. Furthermore, the maintenance process is cumbersome, and damage or failure of the central drive unit can lead to the failure of the entire system. Additionally, the load-bearing cables have sufficient pre-tension, meaning that replacing the central drive unit requires completely dismantling and reinstalling the entire tracking support system to replace the rotating structure. This results in high overall maintenance costs and complicated procedures, severely reducing the system's effectiveness. Utility Model Content

[0006] The main technical problem to be solved by this utility model is to provide a flexible tracking bracket with a central column drive structure that is easy to replace. The overall structure is simple, and it can provide stable rotational support for the central rotating beam, improve the stability of the central rotating beam during rotation, and reduce the force of the central rotating beam on the rotary drive, thereby extending the service life of the rotary drive. It does not require the complete disassembly of the bracket, and it can facilitate the inspection and maintenance of the rotary drive.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A flexible tracking bracket with easy replacement column drive structure includes a support base, a frame rotating beam above the support base, and rotating shafts fixedly installed at the center of the two inner sides of the frame rotating beam. A spliced ​​bearing assembly is installed between the two rotating shafts and the support base to support the frame rotating beam. A rotary driver is detachably installed on the upper end face of the support base between the two rotating shafts. The rotary driver has two power output ends, which are respectively connected to the corresponding rotating shafts for transmission.

[0009] The following are further optimizations of the above technical solution by this utility model:

[0010] The overall structure of the support base includes an upper end plate, a support member is fixedly installed below the upper end plate, and a base plate is fixedly connected below the support member.

[0011] Further optimization: The overall structure of the frame rotating beam includes two spaced rotating beams, with angle steel fixedly installed between the two ends on the same side of the two rotating beams. The connection between the rotating beams and the angle steel is a fixed connection assembled into a square frame shape.

[0012] Further optimization: The rotating shafts are respectively fixedly installed on the side surfaces of the two rotating beams that are close to each other, the rotating shafts pass through the rotating beams, and the connection between the rotating shafts and the rotating beams is a fixed connection.

[0013] Further optimization: A second connecting flange is fixedly installed on one end of the two rotating shafts that are close to each other, and the second connecting flange has multiple mounting through holes.

[0014] Further optimization: The two power output ends of the rotary drive are respectively fixedly installed with a first connecting flange; the first connecting flange is provided with multiple mounting through holes.

[0015] Further optimization: The distance between the two second connecting flanges on one side that is close to each other is L1; the distance between the two first connecting flanges on one side that is far from each other is L2; ​​distance L1 > distance L2.

[0016] Further optimization: After the rotary drive is fixedly installed on the upper end plate, the first connecting flange on one side of the rotary drive is mated with the corresponding second connecting flange and fixedly connected with bolt fasteners. The first connecting flange and the corresponding second connecting flange on the other side of the rotary drive are arranged at intervals and connected by a pin shaft.

[0017] Further optimization: The spliced ​​bearing assembly includes a first bearing housing and a second bearing housing, which are respectively fixedly mounted on the upper end plate. The upper ends of the first bearing housing and the second bearing housing are rotatably connected to the corresponding rotating shafts.

[0018] Further optimization: The first bearing housing and the second bearing housing have the same overall structure, both including a lower bearing body and an upper bearing body. The lower bearing body is detachably mounted on the upper end plate of the support base, and the upper bearing body is detachably mounted on the lower bearing body.

[0019] This utility model adopts the above-mentioned technical solution, which is ingeniously conceived, rationally structured, and simple in overall structure. It can provide stable rotational support for the central rotating beam, improve the stability of the central rotating beam during rotation, and reduce the force exerted by the central rotating beam on the rotary drive, thereby extending the service life of the rotary drive. Each component of the overall structure can be disassembled independently. When inspection and maintenance are required, it is not necessary to completely dismantle the entire support. Only the components that need to be disassembled for inspection and maintenance need to be disassembled and repaired, without affecting the stability of the overall structure. This facilitates the inspection and maintenance of the rotary drive. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model; all other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0033] Example 1: As Figure 1-9 As shown: A flexible tracking bracket with easy replacement column drive structure includes a support base 3, a frame rotating beam 2 is arranged above the support base 3, and a rotating shaft 201 is fixedly installed at the center of the two inner sides of the frame rotating beam 2. A spliced ​​bearing assembly is arranged between the two rotating shafts 201 and the support base 3. The spliced ​​bearing assembly is used to support the frame rotating beam 2. A rotary driver 1 is detachably installed on the upper end face of the support base 3 between the two rotating shafts 201. The rotary driver 1 has two power output ends, and the two power output ends of the rotary driver 1 are respectively connected to the corresponding rotating shafts 201 for transmission.

[0034] In this embodiment, the rotary drive 1 is detachably fixed on the support base 3, and the frame rotating beam 2 is rotatably mounted on the support base 3 using a spliced ​​bearing assembly. Therefore, when the rotary drive 1 needs to be repaired or replaced, the connection between the two power output ends of the rotary drive 1 and the rotating shaft 201 is first disassembled, so that the power output ends of the rotary drive 1 are separated from the rotating shaft 201. Then, the rotary drive 1 is removed from the support base 3, so that the rotary drive 1 can be repaired or replaced. At this time, the bearing assembly supports the frame rotating beam 2.

[0035] In this embodiment, the overall structure of the support base 3 includes an upper end plate 301, a support member 302 is fixedly installed below the upper end plate 301, and a base plate 303 is fixedly connected below the support member 302.

[0036] The support member 302 is composed of multiple steel plates arranged longitudinally and transversely. The upper end of the support member 302 is fixedly connected to the upper end plate 301, and the lower end of the support member 302 is connected to the bottom plate 303. The support member 302 allows the upper end plate 301 and the bottom plate 303 to be arranged at intervals, which facilitates the installation of various components by passing through bolts.

[0037] The base plate 303 can be fastened to the top of the column by bolts or directly welded to the top of the column.

[0038] Multiple mounting holes 304 are provided on the upper end plate 301 at positions corresponding to the rotary driver 1. The rotary driver 1 is placed on the upper end plate 301, and bolts are inserted into the rotary driver 1 and the mounting holes 304 to detachably install the rotary driver 1 onto the upper end plate 301, which facilitates assembly and installation.

[0039] The overall structure of the frame rotating beam 2 includes two spaced rotating crossbeams 204. Angle steel 203 is fixedly installed between the two ends on the same side of the two rotating crossbeams 204. The connection between the rotating crossbeams 204 and the angle steel 203 is fixedly connected, and they are assembled into a square frame-shaped frame rotating beam 2.

[0040] The rotating shaft 201 is fixedly installed on one side of the two rotating beams 204 that are close to each other. The rotating shaft 201 passes through the rotating beam 204, and the connection between the rotating shaft 201 and the rotating beam 204 is a fixed connection.

[0041] A second connecting flange 202 is fixedly installed on the inner end face of each of the two rotating shafts 201, and multiple mounting through holes are provided on the second connecting flange 202.

[0042] The rotary drive 1 has a first connecting flange 101 fixedly installed on each of its two power output ends; the first connecting flange 101 has multiple mounting through holes.

[0043] The first connecting flange 101 on the two power output ends of the rotary drive 1 is respectively connected to the corresponding second connecting flange 202, so that the two power output ends of the rotary drive 1 can be connected to the corresponding rotating shaft 201 for transmission.

[0044] like Figure 2 As shown, in this embodiment, the distance between the two second connecting flanges 202 that are close to each other on one side is L1; the distance between the two first connecting flanges 101 that are far from each other on one side is L2; ​​the distance L1 > the distance L2.

[0045] like Figure 2-3 As shown, during assembly, the rotary drive 1 is fixedly mounted on the upper end plate 301 of the support base 3 using bolts and fasteners passing through the mounting holes 304. At this time, the first connecting flange 101 on one side of the rotary drive 1 is mated with the corresponding second connecting flange 202, and the two are in surface contact. Then, bolts and fasteners are inserted into the mounting through holes on the first connecting flange 101 and the second connecting flange 202 to fix them together. The first connecting flange 101 and the corresponding second connecting flange 202 on the other side of the rotary drive 1 are arranged at intervals, and the interval is the size of the distance L1 minus the distance L2. The rotary drive 1 can be easily assembled and disassembled through this interval. A pin is inserted into the mounting through holes of the corresponding first connecting flange 101 and second connecting flange 202, and a limit pin is inserted at both ends of the pin. The first connecting flange 101 and the second connecting flange 202 are connected by the pin, so that the two power output ends of the rotary drive 1 can be connected to the corresponding rotating shaft 201, which facilitates assembly.

[0046] The spliced ​​bearing assembly includes a first bearing seat 4 and a second bearing seat 5. The first bearing seat 4 and the second bearing seat 5 are respectively fixedly installed on the upper end plate 301, and the upper ends of the first bearing seat 4 and the second bearing seat 5 are rotatably connected to the corresponding rotating shaft 201.

[0047] This design allows the corresponding rotating shaft 201 to be rotatably installed through the cooperation of the first bearing seat 4 and the second bearing seat 5, thereby enabling the frame rotating beam 2 to be rotatably installed on the support seat 3, which is convenient for assembly and installation. Furthermore, the force on the frame rotating beam 2 can be transmitted to the support seat 3 through the first bearing seat 4 and the second bearing seat 5, making it convenient to use.

[0048] In this embodiment, the first bearing housing 4 and the second bearing housing 5 have the same overall structure, both including a lower bearing body 401 and an upper bearing body 402.

The upper bearing body 402 and the lower bearing body 401 are also detachably mounted using connecting bolts 403, which facilitates assembly and installation. Furthermore, the first bearing seat 4 and the second bearing seat 5 are spliced ​​structures, which facilitates the maintenance of the first bearing seat 4 and the second bearing seat 5.

[0050] The lower bearing body 401 and the upper bearing body 402 are respectively provided with grooves on their side surfaces that are close to each other. After the upper bearing body 402 is assembled on the lower bearing body 401, the grooves on the lower bearing body 401 and the upper bearing body 402 are spliced ​​together to form a support hole, and the support hole is rotatably engaged with the corresponding rotating shaft 201.

[0051] In use, the support base 3 is fixedly installed on the central column of the flexible photovoltaic bracket by bolts or welding. The first bearing seat 4 and the second bearing seat 5 are respectively fixedly installed on the upper end plate 301 of the support base 3 by connecting bolts 403. The first bearing seat 4 and the second bearing seat 5 are rotatably connected to the corresponding rotating shaft 201, so that the frame rotating beam 2 can be rotatably installed on the support base 3, which is convenient for assembly and installation. At this time, the first bearing seat 4 and the second bearing seat 5 are used to support the rotation of the frame rotating beam 2.

[0052] The rotary drive 1 is also fixedly mounted on the upper end plate 301 with bolt fasteners and is located in the middle of the two rotating shafts 201. The first connecting flanges 101 on the two power output ends of the rotary drive 1 are respectively connected to the corresponding second connecting flanges 202. One set of first connecting flanges 101 and second connecting flanges 202 are fixedly connected with bolt fasteners, and the other set of first connecting flanges 101 and second connecting flanges 202 are connected with pins for transmission.

[0053] At this time, the rotary drive 1 starts and outputs rotational power, which, through the cooperation of the first connecting flange 101, the second connecting flange 202 and the rotating shaft 201, can drive the frame rotating beam 2 to rotate, making it convenient to use.

[0054] When the rotary drive 1 needs to be repaired, firstly, the connection between the first connecting flange 101 and the second connecting flange 202 is disassembled, and then the connection between the rotary drive 1 and the upper end plate 301 is disassembled. The rotary drive 1 can then be removed from the support base 3 for repair and replacement. This makes it convenient to use, reduces the difficulty of repairing the rotary drive 1, and lowers production and usage costs.

[0055] Example 2, as Figure 10-11 As shown: Based on the above embodiment 1, in this embodiment 2, the frame rotating beam 2 is replaced by a rotating crossbeam 204, that is, a rotating crossbeam 204 is directly rotatably installed on the support base 3.

Steel cable connectors are fixedly installed at both ends of the rotating crossbeam 204, and the steel cable connectors are connected to the corresponding cable assemblies.

[0056] In this embodiment, a rotating shaft 201 is fixedly installed at the middle position of the rotating beam 204. The two ends of the rotating shaft 201 pass through the two sides of the rotating beam 204, and a first bearing seat 4 and a second bearing seat 5 are rotatably installed on the outer surface of the rotating shaft 201 near its two ends. The first bearing seat 4 and the second bearing seat 5 are detachably installed on the upper end plate 301 by connecting bolts 403.
