Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, specifically an adjustment structure based on a fixed adjustable photovoltaic support. Background Technology

[0002] Fixed adjustable brackets can be tilted within a certain range by means of manual or electric means to adapt to changes in the solar altitude angle in different seasons or at different times, thereby increasing the power generation of photovoltaic modules. They are usually used in areas with high power generation requirements and large variations in sunlight conditions.

[0003] CN 222301695 U describes an adjustable-angle fixed solar photovoltaic support with a wind and sand resistant structure, relating to the field of photovoltaic power generation technology. This utility model includes a mounting plate, with a protective shell fixedly connected to the top of the mounting plate. A solar panel is mounted on the top of the protective shell. An adjustment component is located inside the protective shell, including a support plate fixed inside the protective shell. A motor is fixedly connected to the top front of the support plate, and a rotating rod is fixedly connected to the motor's output end. The motor's operation drives the rotating rod to rotate, which in turn drives the connecting plate to rotate, thereby rotating the solar panel through the fixed plate. This achieves the purpose of adjusting the viewing angle. The reinforcement plate and inclined plate effectively enhance the wear resistance of the photovoltaic support. Combined with a dust brush, it effectively prevents sand and gravel from entering the shell, thus reducing the impact of wind and sand on the photovoltaic support. This technical solution includes a hinged section below the middle of the solar panel, allowing for tilt angle adjustment of the photovoltaic panel through the swinging of the support rod. However, the overall support rod has limited support capacity for the solar panel, and under significant external force (strong wind), the solar panel may flip. Utility Model Content

[0004] Technical solution

[0005] To address the shortcomings of existing technologies, this utility model provides an adjustment structure based on a fixed adjustable photovoltaic bracket, which solves the problem mentioned in the background art that existing fixed adjustable photovoltaic brackets lack support and are easily overturned by external forces.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: an adjustment structure based on a fixed adjustable photovoltaic bracket, including a fixed frame, a support frame provided in the middle of the fixed frame, a photovoltaic panel support component rotatably connected to the support frame, and limit units provided on both sides of the support frame above the fixed frame, with the top of the limit units contacting the photovoltaic panel support component, and the limit units on both sides simultaneously adjusting in opposite height directions, the height of the limit units being adjusted by an adjustment unit.

[0007] Furthermore, the limiting unit includes a telescopic sleeve, and the adjusting unit is a circulating pump that connects and passes through the two telescopic sleeves.

[0008] Furthermore, the limiting unit includes a support frame, the top of which contacts the photovoltaic panel support component, and limiting shafts are slidably connected to both sides of the support frame, with the limiting shafts being fixedly connected to the fixing frame.

[0009] Furthermore, the adjustment unit includes a threaded shaft, which is threadedly connected to the middle of the support frame. A driven gear is fixedly installed on the outer surface of the bottom end of one of the threaded shafts. A driving gear with equal ratio transmission is rotatably connected above the fixed frame. A rotating sprocket is fixedly installed above the driving gear and on the outer surface of the other threaded shaft. The two rotating sprockets are connected by the same chain drive.

[0010] Furthermore, a housing that wraps around the outer surface of the adjustment unit is fixedly installed on the upper surface of the fixing frame.

[0011] Furthermore, a drive sprocket is rotatably connected to the upper surface of the fixed frame, and the drive sprocket is chain-driven with one of the threaded shafts. The control end of the drive sprocket extends to the lower part of the fixed frame.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The adjustable structure based on the fixed adjustable photovoltaic bracket, by setting limiting units on both sides of the support frame that can be adjusted in opposite directions at the same time, can support the photovoltaic panel support components from both sides, thereby avoiding the problem that the photovoltaic panel and photovoltaic panel support components are prone to swaying when supported from only one side and subjected to external forces.

[0014] 2. The adjustment structure based on the fixed adjustable photovoltaic bracket has a drive sprocket rotatably connected to the upper surface of the fixed frame. The drive sprocket is chain-driven with one of the threaded shafts. The control end of the drive sprocket extends to the bottom of the fixed frame. With this setting, only the control end of the drive sprocket needs to be adjusted to realize the synchronous rotation of the threaded shafts on both sides in opposite directions, thereby adjusting the tilt angle of the photovoltaic panel support component.

[0020] 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.

[0021] See Figures 1-4 An adjustable structure based on a fixed adjustable photovoltaic bracket includes a fixed frame 1, a support frame 2 in the middle of the fixed frame 1, a photovoltaic panel support component 3 rotatably connected to the support frame 2, and limit units 4 on both sides of the support frame 2 above the fixed frame 1. The top of the limit units 4 contacts the photovoltaic panel support component 3, and the limit units 4 on both sides can be adjusted in opposite directions at the same time. The height of the limit units 4 is adjusted by an adjustment unit 5. By setting limit units 4 on both sides of the support frame 2 that can be adjusted in opposite directions at the same time, the photovoltaic panel support component 3 can be supported from both sides, thereby avoiding the problem that the photovoltaic panel and the photovoltaic panel support component 3 are prone to swaying when supported from only one side and subjected to external forces.

[0022] The limiting unit 4 includes a telescopic sleeve 401, and the adjusting unit 5 is a circulation pump 501 that connects and passes through the two telescopic sleeves 401. The telescopic sleeves 401 are hydraulic. The circulation pump 501 pumps liquid in different directions by changing the rotation direction of the motor. The circulation pump 501 draws a specified amount of hydraulic oil from one side of the telescopic sleeve 401 and pumps it into the other side of the telescopic sleeve 401. The side of the telescopic sleeve 401 that is pumped out contracts, and the side of the telescopic sleeve 401 that is pumped in extends. The two are carried out simultaneously. Since the dimensions on both sides are the same, the rising distance and the falling distance are the same, so that the photovoltaic panel support component 3 can rotate.

[0023] In another embodiment, the limiting unit 4 includes a support frame 403, the top of which contacts the photovoltaic panel support component 3, and the two sides of the support frame 403 are slidably connected to limiting shafts 404. The limiting shafts 404 are fixedly connected to the fixing frame 1. By setting the limiting shafts 404 and the support frame 403, the support frame 403 can be prevented from shaking or rotating.

[0024] The adjusting unit 5 includes a threaded shaft 502, which is threadedly connected to the middle of the support frame 403. The threaded shafts 502 on both sides have the same thread direction. A driven gear 503 is fixedly installed on the outer surface of the bottom end of one of the threaded shafts 502. A driving gear 504 with equal ratio transmission is rotatably connected above the fixed frame 1. The driven gear 503 and the driving gear 504 have the same number of teeth. The cooperation between the driven gear 503 and the driving gear 504 plays the role of reversing direction. A rotating sprocket 505 is fixedly installed above the driving gear 504 and on the outer surface of the other threaded shaft 502. The two rotating sprockets 505 are the same size and have equal ratio transmission. The two rotating sprockets 505 are connected by the same chain 509.

[0025] The upper surface of the mounting bracket 1 is fixedly mounted with a housing 507 that covers the outer surface of the adjustment unit 5. By setting the housing 507, the adjustment unit 5 can be protected and impurities can be prevented from entering and affecting the transmission.

[0026] A drive sprocket 508 is rotatably connected to the upper surface of the fixed frame 1. The drive sprocket 508 is chain driven to one of the threaded shafts 502. The control end of the drive sprocket 508 extends to the lower part of the fixed frame 1. With this arrangement, the threaded shafts 502 on both sides can be rotated in opposite directions synchronously by simply adjusting the control end of the drive sprocket 508, thereby adjusting the tilt angle of the photovoltaic panel support component 3.

[0027] In use, by setting limiting units 4 on both sides of the support frame 2, which can simultaneously adjust the height in opposite directions, the photovoltaic panel support component 3 can be supported from both sides. This avoids the problem that the photovoltaic panel and the photovoltaic panel support component 3 are prone to swaying when supported from only one side and subjected to external force.

[0028] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
