DETAILED DESCRIPTION
[0027] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.
[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0030] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0031] See also Figure 1 An embodiment of the present application provides a photovoltaic bracket, including a support column 300, a support structure 200 and an adjustment structure 100, wherein the support column 300 is rotatably connected to the support structure 200, and the support structure 200 is connected to the adjustment structure 100.
[0032] In actual application, the support column 300 is set on the ground to fix the support structure 200 in a preset working position. A photovoltaic panel is provided on the top of the support structure 200. The adjustment structure 100 is connected to the support structure 200 and is used to drive the support structure 200 to rotate, thereby driving the photovoltaic panel to rotate so that it can follow the angle of sunlight and obtain the maximum intensity of sunlight, thereby increasing the energy conversion rate of the photovoltaic panel.
[0033] It should be noted that the photovoltaic support also includes a transmission component 400 and a driving component. The output end of the driving component is connected to the transmission component 400, and the transmission component 400 is connected to the adjustment structure 100, and provides the torque output by the driving component to the adjustment structure 100, so that the adjustment structure 100 can rotate, thereby driving the support structure 200 to rotate. The transmission component 400 can use a worm gear reducer, which allows a very low input speed range and a large deceleration range. It also has a self-locking function, which can more smoothly adjust the rotation angle of the photovoltaic panel.
[0034] See also Figure 1 and Figure 2 The above-mentioned adjustment structure 100 includes an arc-shaped component 1 and a transmission gear 2. The arc-shaped component 1 includes an arc-shaped beam 11 and a plurality of tooth block structures 12. The arc-shaped beam 11 forms at least a portion of an arc. Both ends of the arc-shaped beam 11 are connected to the support structure 200.
[0035] The plurality of tooth block structures 12 are detachably connected to the arc beam 11 and are sequentially arranged along the circumferential direction of the arc beam 11. Specifically, the plurality of tooth block structures 12 are arc-shaped, and their curvature is adapted to the curvature of the outer circumference of the arc beam 11, so that the plurality of tooth block structures 12 are connected to the outer side of the arc beam 11 along the circumferential direction of the arc beam 11, and the plurality of tooth block structures 12 are spliced to form a complete circular arc gear; the transmission component 400 is connected to the transmission gear 2 and drives the transmission gear 2 to rotate, and the transmission gear 2 is meshed with at least one tooth block structure 12. When the transmission gear 2 rotates, the transmission gear 2 drives the arc beam 11 to rotate, and further, the arc beam 11 drives the support structure 200 to rotate, so as to adjust the angle of the photovoltaic panel. The tooth block structure 12 and the arc beam 11 can be connected by gluing or bolting.
[0036] In the prior art, the arc beam 11 and the gear are usually processed into one piece, and the arc beam 11 is generally processed using an existing mold. If the arc beam 11 and the gear are formed in one piece, the existing mold cannot be used, and a new mold needs to be produced, which increases the difficulty of the operation and extends the construction period. In this way, the gear and the arc beam 11 need to be cast from the same material. In order to ensure the stability of the bracket, the arc beam 11 usually needs to be made of metal, and the gear formed integrally with it must also be made of metal. This setting greatly increases the production cost, and the gears made of metal are prone to corrosion, which reduces the service life of the photovoltaic bracket. The present application connects the tooth block structure 12 and the arc beam 11 detachably, so that the tooth block structure 12 and the arc beam 11 can be produced independently of each other, and the two can be made of different materials, which effectively reduces the production cost. At the same time, the tooth block structure 12 and the arc beam 11 can be transported to the working position separately, which greatly facilitates the transportation of the device; multiple tooth block structures 12 are spliced to form a complete circular arc gear, which makes the connection between the tooth block structure 12 and the arc beam 11 simpler and further makes transportation more convenient.
[0037] The diameter of the transmission gear 2 is smaller than the radius of the arc beam 11. Specifically, the transmission gear 2 is connected to at least one tooth block structure 12 located in the arc portion of the arc beam 11 to transmit the torque output by the driving component to the arc beam 11. The arc beam 11 is arranged to be an arc with a larger radius, so that it can amplify the torque transmitted by the transmission gear 2, so that the arc beam 11 can achieve a large output torque with a small input torque, thereby driving the photovoltaic panel to rotate. Therefore, the driving component of the device can adopt a smaller-sized driving machine, further reducing the production cost.
[0038] See also Figure 3 and Figure 4 The arc beam 11 includes a main body 111 and a bending portion 112. The main body 111 forms at least a portion of a circular arc. The bending portions 112 are provided on opposite sides of the main body 111. The bending portions 112 on the opposite sides are bent in directions approaching each other. The bending portions 112 and the main body 111 are surrounded to form a limiting groove 113. The tooth block structure 12 is at least partially provided in the limiting groove 113.
[0039] In this embodiment, two relatively arranged bending portions 112 are bent in a direction approaching each other, and the bending angle can be set to 30° to 60°. The bending portions 112 extend along the circumferential direction of the main body 111, so that they and the main body 111 are surrounded to form a limiting groove 113, and the tooth block structure 12 is located in the limiting groove 113. The limiting groove 113 limits the relative movement of the tooth block structure 12 and the main body 111, thereby increasing the stability of the connection between the two.
[0040] See also Figure 5The tooth block structure 12 includes a connecting plate 121 and a plurality of teeth 122. The connecting plate 121 is connected to the main body 111. The plurality of teeth 122 are sequentially arranged on the connecting plate 121. The two opposite sides of the connecting plate 121 extend outward to form a limiting portion 123. When the connecting plate 121 is connected to the main body 111, the limiting portion 123 is located in the limiting groove 113. The plurality of teeth 122 are used to mesh with the transmission gear 2. The two opposite sides of the connecting plate 121 extend outward to form the limiting portion 123. The size of the limiting portion 123 matches the size of the limiting groove 113, so that it can be limitedly matched with the limiting groove 113 to prevent the connecting plate 121 from moving relative to the main body 111.
[0041] It is understandable that the connecting plate 121 and the tooth portion 122 can be integrally formed for easy production.
[0042] The plurality of tooth block structures 12 include a plurality of first tooth block structures 12A and a plurality of second tooth block structures 12B. The plurality of first tooth block structures 12A are made of plastic, and the plurality of second tooth block structures 12B are made of metal.
[0043] In practical applications, the tooth block structure 12 formed by injection molding is strong enough to resist wind loads under normal climates. Therefore, under normal climates, the transmission gear 2 is meshed with the first tooth block structure 12A. The first tooth block structure 12A is made by injection molding, which reduces production costs and prevents corrosion. In extreme climates, when the wind load is large, the transmission gear 2 is meshed with the second tooth block structure 12B. The second tooth block structure 12B is made of metal, has high rigidity and hardness, can resist large wind loads, and increase the stability of the device.
[0044] See also Figure 7 , multiple second tooth block structures 12B are symmetrically arranged relative to the arc center of the arc beam 11, and the line connecting the center of the second tooth block structure 12B and the arc center of the arc beam 11 is L, wherein the central angle corresponding to L is 15°. In practical applications, when the wind speed exceeds the set wind shelter wind speed, the photovoltaic bracket will enter a wind shelter protection state. In the wind shelter state, the angle between the photovoltaic panel and the horizontal plane is generally at a position of about +15° or -15°, and the second tooth block structure 12B is arranged at a corresponding position. Since the instantaneous wind load of the bracket in the wind shelter state is sometimes very large, in order to avoid damage to the plastic gears, the tooth block material at the position of the second tooth block structure 12B is replaced with high-strength aluminum bronze, which is both corrosion-resistant and wear-resistant, and has a strength far higher than that of ordinary plastic gears, thereby ensuring the safety of the bracket under extreme loads.
[0045] In one embodiment, the arc beam 11 is a high-strength aluminum alloy profile, and is fixed to the plastic tooth block of the first tooth block structure 12A and the aluminum bronze aluminum block of the second tooth block structure 12B by strong glue and limiting grooves 113, so that the two are connected together to form a larger fan-shaped gear, and form a large and small gear transmission structure with the transmission gear 2. This structure is corrosion-resistant, wear-resistant, lightweight and low-cost, ensuring the strength and life of the entire photovoltaic bracket.
[0046] See also Figure 6 and Figure 8 The bending portion 112 includes a first portion 1121 and a second portion 1122. The first portion 1121 is connected to the main body portion 111 and is inclined toward the direction close to the main body portion 111. The inclination angle can be 30° to 60°, which is convenient for the installation of the tooth block structure 12 and effectively limits the tooth block structure 12. If the inclination angle is too small, the limiting effect of the limiting groove 113 will be reduced. If the inclination angle is too large, the size of the limiting groove 113 will be reduced, which is not convenient for the installation of the tooth block structure 12.
[0047] The second part 1122 is connected to the first part 1121 and is inclined toward the direction close to the main body 111, and its inclination angle is 30° to 60°. The second part 1122 further forms a limiting member for limiting the movement of the tooth block structure 12. Through the limiting effect of the first part 1121 and the second part 1122, the connection between the tooth block structure 12 and the main body 111 is more stable.
[0048] See again Figure 6 In one embodiment, mounting grooves 13 are provided at opposite ends of the arc-shaped component 1. Specifically, the mounting grooves 13 are provided at opposite ends of the main body 111. The mounting grooves 13 pass through the main body 111. When installing, the main body 111 can be directly plugged into the support structure 200 through the mounting grooves 13, so that the support structure 200 is installed in the mounting grooves 13, which simplifies the installation steps of the device and facilitates the construction of the photovoltaic bracket.
[0049] The arc-shaped component 1 is also provided with a fixing hole 14, and the fixing hole 14 and the mounting groove 13 are located on two adjacent side surfaces of the arc-shaped component, and the fixing hole 14 is communicated with the mounting groove 13, and the fixing hole 14 is used to fix the support structure 200. Specifically, the fixing hole 14 and the mounting groove 13 are respectively provided on two adjacent side surfaces of the main body 111, and the mounting groove 13 penetrates the main body 111, and the fixing hole 14 penetrates the main body 111 in a direction perpendicular to the mounting groove 13. When the support structure 200 is arranged in the mounting groove 13, a bolt or a rivet or the like can be used to penetrate the fixing hole 14 to fix the main body 111 and the support structure 200 together, which is convenient to operate and easy to construct.
[0050] The embodiment of the present application provides a photovoltaic bracket and its adjustment structure 100, including a support column 300, a support structure 200 and an adjustment structure 100, the support column 300 is rotatably connected to the support structure 200, and the support structure 200 is connected to the adjustment structure 100; the adjustment structure 100 includes an arc-shaped component 1 and a transmission gear 2, the arc-shaped component 1 includes an arc-shaped beam 11 and a plurality of tooth block structures 12, the plurality of tooth block structures 12 are detachably connected to the arc-shaped beam 11, and are arranged in sequence along the circumferential direction of the arc-shaped beam 11, and the transmission gear 2 is meshed with at least one tooth block structure 12. Different from the prior art, the present application connects the tooth block structure 12 and the arc beam 11 detachably, so that the tooth block structure 12 and the arc beam 11 can be produced independently of each other, and the two can be made of different materials, which effectively reduces the production cost. At the same time, the tooth block structure 12 and the arc beam 11 can be transported to the working position separately, which greatly facilitates the transportation of the device; multiple tooth block structures 12 are spliced to form a complete circular arc gear, which makes the connection between the tooth block structure 12 and the arc beam 11 simpler and further makes transportation more convenient.
[0051] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
