[0001] This utility model relates to the technical field of photovoltaic operation and maintenance equipment, and in particular to a mobile offshore photovoltaic operation and maintenance frame. Background Technology

[0002] Photovoltaic power plants generate electricity using solar energy, and are a type of green energy project. Photovoltaic panels are composed of arrays of photovoltaic panels. During long-term use, operators need to perform regular maintenance on the photovoltaic panels to ensure the normal operation of all equipment components in the photovoltaic power plant.

[0003] When operators maintain photovoltaic panels, they need to use two sets of maintenance racks to set up the racks on the photovoltaic panels and move them to the next location for repair. This is very inconvenient, time-consuming and labor-intensive. In addition, photovoltaic panels are usually tilted at a small angle, and the safety of maintenance personnel is not guaranteed when they work on the tilted maintenance racks. Utility Model Content

[0006] A mobile offshore photovoltaic (PV) maintenance frame is erected on an inclined PV panel. The frame includes a main body with legs installed at its corners. Each leg includes a suspended leg and an inclined leg. The suspended leg is positioned on the higher side of the PV panel, and the inclined leg is positioned on the lower side. The vertical height of the inclined leg is adjusted to maintain the frame's horizontal position. A pulley is connected to the bottom of each leg, and the pulley is rolled within the installation gap of the PV panel.

[0007] Preferably, the tilting support includes an upper support arm and a lower support arm. The upper support arm is fixedly installed at the corner of the maintenance frame body. The upper support arm and the lower support arm are hinged together and a buckle is provided at the hinge position. The tilt angle between the upper support arm and the lower support arm is adjusted by the buckle, thereby adjusting the vertical height of the tilting support to complement the tilt angle of the photovoltaic panel and achieve the horizontality of the maintenance frame body.

[0008] Preferably, a motion track is laid in the installation gap of the photovoltaic panel, and the motion track is in rolling cooperation with the pulley.

[0009] Preferably, the maintenance frame body is provided with drivers at both ends, and the drivers drive the pulleys to roll on the motion track.

[0010] Preferably, a damper is provided on one side of the pulley.

[0014] In summary, this utility model has the following beneficial technical effects:

[0015] 1. This utility model provides a mobile offshore photovoltaic (PV) maintenance frame. Support legs and pulleys are set at the four corners of the frame body. The driver drives the pulleys to roll on the movement track between the PV panel installation gaps, which moves the maintenance frame body and the operator to the next PV panel location for maintenance. There is no need to move the maintenance frame body, which makes it convenient for the operator to quickly complete the maintenance work and improves efficiency.

[0023] The following combination Figures 1-5 The present invention will be described in further detail below.

[0024] This utility model discloses a mobile offshore photovoltaic operation and maintenance frame.

[0025] Reference Figure 1 , Figure 2 , Figure 5 A mobile offshore photovoltaic (PV) maintenance frame is horizontally erected on an inclined PV panel 1. It includes a maintenance frame body 2, with support legs 3 installed at the corners of the maintenance frame body 2. The support legs 3 include suspension support legs 4 and inclined support legs 5. The suspension support legs 4 are located on the higher side of the PV panel 1 at a horizontal position, and the inclined support legs 5 are located on the lower side of the PV panel 1 at a horizontal position. The vertical height of the inclined support legs 5 is adjusted to maintain the horizontality of the maintenance frame body 2. The bottom end of the support legs 3 is connected to a pulley 6, which is rolled in the installation gap of the PV panel 1.

[0026] Reference Figure 1 , Figure 2 , Figure 3 The tilting support 5 includes an upper support arm 7 and a lower support arm 8. The upper support arm 7 is fixedly installed at the corner of the maintenance frame body 2. The upper support arm 7 and the lower support arm 8 are hinged together and a buckle 9 is provided at the hinge position. The tilt angle between the upper support arm 7 and the lower support arm 8 can be adjusted by the buckle 9, thereby adjusting the vertical height of the tilting support 5. The tilting supports 5 with different vertical heights are set on the tilted photovoltaic panel 1, which complements the tilt angle of the photovoltaic panel 1, so as to achieve the horizontality of the maintenance frame body 2.

[0027] Reference Figure 2 A buffer spring is provided at the connection point between pulley 6 and support leg 3.

[0028] Reference Figure 1 , Figure 5 The photovoltaic panel 1 is installed with a moving track 10, which is rolled in conjunction with the pulley 6. The tilt angle of the photovoltaic panel 1 is usually between 10° and 15°.

[0029] Reference Figure 1 , Figure 5 The pulleys 6 are rolled on both sides at the edges of adjacent photovoltaic panels 1, and the middle of the pulleys 6 protrudes and is embedded in the motion track 10 of the installation gap of the photovoltaic panels 1. During the installation process, adjacent photovoltaic panels 1 are connected by pressure blocks. When the pulleys 6 roll on the motion track 10, there is obstruction from the pressure blocks. By setting the pulleys 6 to roll on both sides at the edges of adjacent photovoltaic panels 1, and the middle of the pulleys 6 protruding and being embedded in the motion track 10 of the installation gap of the photovoltaic panels 1, and cooperating with the chamfered edge of the pressure blocks, the obstruction of the pressure blocks when the pulleys 6 roll on the motion track 10 is overcome.

[0030] Reference Figure 1 , Figure 5The photovoltaic panel 1 has a barrier strip on its edge to block the maintenance frame body 2 and prevent the risk of falling.

[0031] Reference Figure 2 , Figure 5 The maintenance frame body 2 is equipped with two drivers 11 at both ends. The two drivers drive the pulleys 6 to roll on the motion track 10. The drivers 11 can use the drive part of an existing electric lift, which drives the pulleys 6 to roll on the motion track 10 through the transmission belt. The drivers 11 lock the pulleys 6 with locking parts 13. The maintenance frame body 2 is equipped with an operating handle to control the drive of the drivers 11. The maintenance personnel control the movement of the maintenance frame body 2 on the motion track 10 by operating the handle.

[0032] Reference Figure 1 , Figure 2 , Figure 3 A damper 12 is provided on one side of the pulley 6. The damper 12 prevents the maintenance frame body 2 from sliding when not driven by the driver 11, making it convenient for maintenance personnel to move and inspect the maintenance frame body 2.

[0033] Reference Figure 4 The main body of the maintenance frame 2 is made of square tube 14. Two square tubes 14 are cut and a support strip 15 is fixed between the two square tubes 14. The structure is simple and has a wide range of applications.

[0034] Reference Figure 4 The support bar 15 is provided with anti-slip texture 16 to prevent maintenance personnel from slipping when moving on the maintenance frame body 2.

[0035] Reference Figure 4 The cut surfaces at the ends of the square tube 14 are provided with rubber corner protectors 17.

[0036] The implementation principle of this utility model embodiment is as follows: Assemble the maintenance frame body 2, and install support legs 3 at the corners of the maintenance frame body 2. Horizontally mount the maintenance frame body 2 on the inclined photovoltaic panel 1. The inclined support legs 5, which can adjust vertical height, are located on the lower side of the photovoltaic panel 1 at its horizontal position, while the suspension support legs 4 are located on the higher side of the photovoltaic panel 1 at its horizontal position. The pulleys 6 at the bottom of the support legs 3 are rolled within the installation gap of the photovoltaic panel 1. In operation, maintenance personnel stand on the maintenance frame body 2, and the driver 11 drives the maintenance frame body 2 to roll on the movement track 10 within the installation gap of the photovoltaic panel 1. Maintenance personnel then inspect and repair the photovoltaic panels 1 sequentially.

[0037] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be included within the scope of protection of this utility model.
