Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panel installation devices, in particular to a roof photovoltaic panel fixing base. Background Art

[0002] Photovoltaic panels are a type of power generation device. Photovoltaic power generation is different from other common forms of power generation. It does not require prime movers, generators or other rotating equipment, but directly converts sunlight into electrical energy. It is a purely electronic device. Like other electronic products, its performance will continue to improve and its price will continue to decline with the advancement of technology. At the same time, the sun's energy is inexhaustible. Therefore, photovoltaic power generation is known as the ultimate energy source for mankind and has broad room for development.

[0003] Although the current photovoltaic panel installation structure is relatively mature, there are still some defects. For example, the photovoltaic panel bracket disclosed in the publication number [CN218276595U] connects the purlins, the middle pressure and the side pressure through bolts to achieve the fixation of the photovoltaic panel and the bracket. However, the photovoltaic panel and its fixing device are generally at a certain angle during installation, that is, they are placed at an angle and fixed as a whole by a bolt fixing device. However, most of the existing photovoltaic panels need to be arranged in groups during installation, that is, multiple photovoltaic panels are arranged on a fixing device. During installation, each photovoltaic panel needs to be fixed, and they cannot be fixed in groups at the same time. Moreover, when the photovoltaic panel is damaged and needs to be replaced later, the tilted placement causes inconvenience to the unscrewing and tightening of the bolts, and also causes difficulties in installation and replacement, thereby reducing the work efficiency of the staff. Utility Model Content

[0004] The purpose of the utility model is to provide a fixing base which can ensure the convenience of installing a photovoltaic panel and the stability after installation.

[0005] To this end, the utility model adopts the following technical solutions:

DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

A clamping portion for abutting the photovoltaic panel is arranged at the bottom of the clamping wing 3, and an elastic limiting section for pre-limiting the photovoltaic panel is arranged between the clamping wing 3 and the base 1, and a connecting rod 5 extending into the receiving cavity is arranged at the bottom of the clamping wing 3, and the connecting rod 5 is slidably connected to the inner wall of the receiving cavity so that the connecting rod 5 can be moved up and down to adjust the distance between the clamping wing 3 and the photovoltaic panel, and a linkage component connected and cooperated with the connecting rod 5 is arranged in the receiving cavity, and a knob 17 extending into the receiving cavity and connected to the linkage component is arranged outside the base 1, and a locking component for locking the photovoltaic panel after installation is arranged on the linkage component or the knob 17.

[0024] In this embodiment, the base 1 is provided with protrusions on both sides of the photovoltaic panel arrangement area in opposite directions to limit the required placement area of ​​the photovoltaic panel, and the base 1 is provided with anti-slip strips 2 in the photovoltaic panel arrangement area to reduce the slippage of the photovoltaic panel before it is completely fixed.

[0025] In this embodiment, the clamping assembly is provided with a first spring 4 between the clamping wing 3 and the base 1, one end of the first spring 4 is connected to the bottom of the clamping wing 3, and the other end is connected to the base 1, and the first spring 4 can be sleeved around the outer periphery of the connecting rod 5. The first spring 4 can realize the initial pre-positioning restriction of the photovoltaic panel on the base 1.

[0026] like Figure 1 and 3As shown, in this embodiment, a number of clamping wings 3 are arranged along the edges of both sides of the base 1, and a first linkage rod 8 is horizontally arranged in the accommodating cavity of the base 1. The first linkage rod 8 is rotatably connected to the inner wall of the accommodating cavity, and a gear 7 is sleeved on the first linkage rod 8. The number of gears 7 is the same as the number of connecting rods 5 connected to the clamping wings 3, and a rack 6 meshing with the gear 7 is arranged on the connecting rod 5.

[0027] like Figure 3-4 As shown, in order to enable the clamping wings 3 on both sides of the base 1 to be lifted or moved down synchronously, a second linkage rod 11 is provided in the longitudinal direction of the base 1. The second linkage rod 11 is located in the area below the photovoltaic panel arrangement area, and the area is the interval space between the photovoltaic panel arrangement area of ​​the base 1 and the roof wall. At the same time, the end portions on both sides of the second linkage rod 11 extend into the accommodating cavities on both sides of the base 1 respectively, and a transmission assembly that cooperates with each other is provided between the rod section of the second linkage rod 11 extending into the accommodating cavity and the first linkage rod 8.

[0028] In this embodiment, the transmission assembly adopts a worm gear structure, whereby a worm 10 is provided on the rod section of the second linkage rod 11 extending into the accommodating cavity, and a turbine 9 meshing with the worm 10 is provided on the first linkage rod 8 .

[0029] At the same time, the knob 17 is fixedly connected to one side end of the second linkage rod 11, so that by rotating the knob 17, the second linkage rod 11 can realize the synchronous movement of multiple clamping wings 3 to realize the disassembly and installation of the photovoltaic panel.

[0030] like Figure 1-2 As shown, in this embodiment, the locking assembly is provided with a ratchet 12 outside the knob 17, and a pawl 13 cooperating with the ratchet 12 is provided on the outer surface of the base 1, the pawl 13 is rotatably connected to the base 1, and the other end of the pawl 13 is clamped in the groove of the ratchet 12, and a second spring 16 is connected to the base 1, and the other end of the second spring 16 is connected to the pawl 13. Through the cooperation of the ratchet 12 and the pawl 13, the second linkage rod 11 is prevented from reversing, thereby avoiding the unstable installation of the photovoltaic panel.

[0031] At the same time, a pull rope 14 is connected to the pawl 13 , and the pull rope 14 is used to release the locking of the pawl 13 on the ratchet 12 , thereby facilitating the reversal of the knob 17 .

[0032] See also Figure 1-4 When installing and disassembling the photovoltaic panel through the fixed base, the specific disassembly contents are as follows:

[0033] When installing photovoltaic panels, the staff can place the photovoltaic panels in the photovoltaic layout area and use the clamping wings 3 to cooperate with the first spring 4 on the panels on both sides of the photovoltaic panels to achieve the initial pre-fixation of the photovoltaic panels and the base 1. After the staff has placed the photovoltaic panels in groups, they rotate the knob 17 to rotate the second linkage rod 11 and drive the worm wheel 9 and the worm 10 to rotate, thereby driving the first linkage rod 8 and the gear 7 to rotate, and the connecting rod 5 moves downward under the action of the rack 6, thereby driving all the clamping wings 3 to abut the photovoltaic panels more tightly, that is, to achieve the group fixation of the photovoltaic panels. And after the knob 17 stops rotating, the installation of the photovoltaic panels is completed by locking the ratchet 12 with the pawl 13.

[0034] When the photovoltaic panel needs to be replaced or repaired, pull the pull rope 14 to release the lock of the pawl 13 on the ratchet 12, reverse the knob 17, reverse the second linkage rod 11, so that the connecting rod 5 moves upward, and then the clamping wings 3 on both side areas are lifted synchronously, thereby facilitating the disassembly of the photovoltaic panel.

[0035] The above embodiment is only a preferred technical solution of the present invention. Those skilled in the art should understand that the technical solutions or parameters in the embodiments can be modified or replaced without departing from the principle and essence of the present invention, and all should be included in the protection scope of the present invention.
