Description

Technical Field

[0001] This utility model relates to the technical field of welding positioning devices, specifically a photovoltaic bracket welding positioning device. Background Technology

[0002] In existing technologies, photovoltaic brackets are often used when installing photovoltaic panels, and these brackets often need to be welded and fixed when they are extended.

[0003] In existing photovoltaic (PV) brackets, there are generally at least four columns for support, and a rectangular frame at the top for fixing the PV panels. In existing technologies, fixing the columns is relatively simple; clamps are used to fix the columns and then they are welded to the rectangular frame at the top. However, welding the rectangular frame is more complicated. There is a lack of a positioning device that can quickly and simultaneously fix all four sides of the rectangular frame to facilitate welding. In addition, since the rectangular frame has a certain tilt angle to facilitate better power generation after the solar panels are fixed, the corresponding positioning device should also have a certain tilt function. Therefore, an improved PV bracket welding positioning device is needed to address this issue. Utility Model Content

[0004] The purpose of this invention is to provide a photovoltaic bracket welding positioning device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a photovoltaic bracket welding positioning device, comprising a base plate, a fixing mechanism provided at the upper end of the base plate, the fixing mechanism comprising a column, a first rotating connecting arm, a second rotating connecting arm, a movable rod, a mounting plate, and clamping buckles, the base plate being fixedly provided with columns around its upper perimeter, the upper end of the column being movably provided with a first rotating connecting arm via a rotating shaft, one end of the first rotating connecting arm being movably provided with a second rotating connecting arm via a rotating shaft, the lower end of the second rotating connecting arm being movably inserted with a movable rod, the lower end of the movable rod being fixedly provided with a mounting plate, clamping buckles being provided on both sides of the lower end of the mounting plate, and a crossbeam being provided between the clamping buckles.

[0006] Preferably, both the second rotating connecting arm and the outer surface of the movable rod are provided with through grooves, and a pin is provided between the through grooves. The extension length of the movable rod can be changed by inserting the pin into different through grooves.

[0007] Preferably, multiple through slots are provided and are evenly spaced on the outer surface of the movable rod and the second rotating connecting arm. This allows the movable rod to have a variety of different lengths, so that the device can fix the crossbeam at a variety of different heights.

[0008] Preferably, a locking screw is provided at one end of the shaft where the first rotating connecting arm and the second rotating connecting arm are located. The locking screw can be tightened and locked after the first rotating connecting arm and the second rotating connecting arm are adjusted to a predetermined angle, thereby fixing the first rotating connecting arm and the second rotating connecting arm.

[0009] Preferably, a fixing screw is provided between the clamping buckle and the mounting plate. The device has two clamping buckles, which are respectively fixed to the lower end of the mounting plate by fixing screws to fix the crossbeams. After all the crossbeams are welded to form a frame structure, it is only necessary to remove the fixing screws to remove the clamping buckles and then remove the crossbeams that have been welded into a frame.

[0010] Preferably, a compression screw is provided on one side of the clamping buckle surface via a threaded connection. The compression screw compresses the crossbeam inside the clamping buckle, which, in conjunction with the clamping buckle, can further fix the crossbeam.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model uses a fixing screw to fix the clamping buckle, thereby fixing the crossbeam to be welded and suspending it in the air. Then, the crossbeam inside the clamping buckle is pressed by the squeezing screw, which, together with the clamping buckle, can further fix the crossbeam. Then welding can be carried out. Since four crossbeams are fixed at the same time during welding, welding is convenient.

[0013] When using this utility model, the first rotating connecting arm and the second rotating connecting arm can be tilted at multiple angles, so that the device can tilt and weld photovoltaic bracket frames at multiple angles. After the frame part is welded, it is only necessary to vertically fix the columns at the four corners of the lower surface of the frame part, and then weld the columns and the frame to complete the overall welding work of the photovoltaic bracket.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a photovoltaic bracket welding positioning device, including a base plate 1. A fixing mechanism is provided on the upper end of the base plate 1. The fixing mechanism includes a column 2, a first rotating connecting arm 3, a second rotating connecting arm 4, a movable rod 5, a mounting plate 6, and clamping buckles 7. The column 2 is fixedly arranged around the upper end of the base plate 1. The first rotating connecting arm 3 is movably arranged on the upper end of the column 2 through a rotating shaft. The second rotating connecting arm 4 is movably arranged on one end of the first rotating connecting arm 3 through a rotating shaft. The movable rod 5 is movably inserted at the lower end of the second rotating connecting arm 4. The mounting plate 6 is fixedly arranged at the lower end of the movable rod 5. Clamping buckles 7 are provided on both sides of the lower end of the mounting plate 6. A crossbeam 13 is arranged between the clamping buckles 7.

[0021] The outer surfaces of the second rotating connecting arm 4 and the movable rod 5 are both provided with through grooves 8, and pins 9 are provided between the through grooves 8. The extension length of the movable rod 5 can be changed by inserting the pins 9 into different through grooves 8.

[0022] Multiple through slots 8 are provided and are evenly spaced on the outer surface of the movable rod 5 and the second rotating connecting arm 4, so that the movable rod 5 can be given a variety of different lengths, thereby allowing the device to fix the crossbeam 13 at a variety of different heights.

[0023] A locking screw 10 is provided at one end of the rotating shaft where the first rotating connecting arm 3 and the second rotating connecting arm 4 are located. The locking screw 10 can be tightened and locked after the first rotating connecting arm 3 and the second rotating connecting arm 4 are adjusted to a predetermined angle, thereby fixing the first rotating connecting arm 3 and the second rotating connecting arm 4.

[0024] A fixing screw 11 is provided between the clamping buckle 7 and the mounting plate 6. The device has two clamping buckles 7, which are respectively fixed to the lower end of the mounting plate 6 by fixing screws 11 to fix the crossbeam 13. After all the crossbeams 13 are welded to form a frame structure, it is only necessary to remove the fixing screws 11 to remove the clamping buckle 7 and then remove the crossbeams after they are welded into a frame.

[0025] A compression screw 12 is provided on one side of the surface of the clamping buckle 7 by means of a threaded screw. The compression screw 12 compresses the crossbeam 13 inside the clamping buckle 7, and the clamping buckle 7 can further fix the crossbeam 13.

[0026] Working principle: When using this device, the clamping buckle 7 is fixed by fixing screw 11, so that the crossbeam 13 to be welded can be fixed and suspended in the air. Then, the crossbeam 13 inside the clamping buckle 7 is pressed by pressing screw 12. The clamping buckle 7 can further fix the crossbeam 13, and then welding can be carried out. During welding, four crossbeams 13 are fixed at the same time, which facilitates welding.

[0027] Meanwhile, during use, the first rotating connecting arm 3 and the second rotating connecting arm 4 can be tilted at multiple angles, allowing the device to tilt and weld photovoltaic support frames at various angles. After the frame is welded, as... Figure 1 As shown, at this point, it is only necessary to vertically fix the column 2 at the four corners of the lower surface of the frame, and then weld the column 2 and the frame to complete the overall welding of the photovoltaic bracket.

[0028] After all the photovoltaic brackets are welded, since the clamping buckle 7 that fixes the photovoltaic brackets is a separate part, you can directly remove the fixing screw 11 of the clamping buckle 7, and then remove the entire photovoltaic bracket after disassembling the clamping buckle 7.
