In order to achieve this purpose, the sun needs to be tracked in the azimuth and elevation angles in use, so that the collector is always aimed at the sun from sunrise to sunset, so as to improve the utilization rate of solar energy. The deflection of the tracker during operation is based on the connection between the bearing and the bearing seat as the bearing basis.

[0003] In the prior art, in order to ensure that the bearing and the bearing seat have a small friction coefficient, reduce wear and tear, and reduce the weight of the assembly to achieve lightweight design, the bearing and the bearing seat are usually made of engineering plastic. In this way, wear and tear during use can be reduced and aging and corrosion phenomena can be avoided when used in external environment for a long time.

The plastic bearing cover will be broken at the bearing seat hole during the operation of the solar support tracker, and needs to be replaced. The number of replacement is large during long-term use, which increases the use cost. At the same time, the connecting bolt between the upper cover and the base reciprocatingly bears the torsional load after the tracker runs for a long time, which causes the connecting part of the bolt to loosen, the upper cover and the base to dislocate and shake, and further affects the stability of the tracker operation.

[0030] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings of the embodiments of the present application. Figures 1-9 It should be apparent that the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0031] In order to solve the problems in the prior art, the embodiment provides a new bearing seat for a photovoltaic tracking support, which comprises a base 1, an upper cover 2 and a bearing 3. The upper cover 2 is provided with eaves 5 on both sides, the base 1 is provided with a boss 6 on which the eaves 5 are placed, and the boss 6 and the eaves 5 are provided with through holes 8 at corresponding positions. A D-shaped bolt 4 is inserted into the through hole 8 and abuts against the side wall of the upper cover 2, so that the detachable connection between the upper cover 2 and the base 1 is realized. The D-shaped bolt 4 abuts against the side wall of the upper cover 2, the plane of the head of the D-shaped bolt 4 is tangent to the outer edge surface of the upper cover 2, so that the D-shaped bolt 4 cannot rotate, the self-positioning of the D-shaped bolt 4 is realized, the loosening caused by stress deflection is prevented, the connection tightness between the upper cover 2 and the base 1 is improved, and the stability of the tracker operation is improved; when the nut is screwed, the bolt does not need to be limited by additional parts, and the locking of the nut is facilitated.

[0032] The boss 6 is provided with a limiting ring 7 coaxial with the through hole 8, and the limiting ring is embedded into the through hole 8 on the eave 5. Through the cooperation of the limiting ring 7 and the through hole 8, the horizontal strength between the upper cover 2 and the base 1 is strengthened, and the horizontal force resistance of the D-shaped bolt 4 is enhanced.

[0033] The inner wall of the bearing seat hole of the base 1 and the upper cover 2 and the outer edge surface of the bearing 3 are spherical surfaces, and a self-lubricating plastic bearing 3 with a spherical outer surface is embedded in the base 1 and the upper cover 2. The spherical design forms an outer spherical bearing 3, so that the device embedded in the self-lubricating plastic bearing 3 can deflect to a certain extent. The maximum diameter of the spherical surface can limit the bearing 3 from being withdrawn from the bearing seat. The self-lubricating plastic bearing 3 is made of self-lubricating bearing 3 material. It has good self-lubricating property, wear resistance and good ultraviolet resistance. The self-lubricating bearing 3 material refers to a material that can exhibit low friction characteristics even without external lubricant. Among them, plastics such as tetrafluoroethylene resin contain solid lubricants such as graphite and two-fluid molybdenum, and plastic bearing 3 materials.

[0034] In the embodiment, the D-shaped bolt 4 includes a D-shaped head and a tooth part, and the plane of the head is an arc surface that fits the outer edge surface of the upper cover 2. The contact area between the head of the D-shaped bolt 4 and the outer edge surface of the upper cover 2 is increased, so that the tangent line contact between the original plane and the arc surface is changed into the surface contact between the arc surfaces, the torsional load bearing is more dispersed, and stress concentration is avoided.

[0035] In the embodiment, the outer edge surfaces of the upper cover 2 and the base 1 are provided with flanges 9 on both sides. The wrapping of the bearing 3 is better. Through the cooperation of the spherical surface design of the bearing seat hole inner ring of the upper cover 2 and the base 1 and the flange 9, the embedded bearing 3 can freely rotate within a range of ±10° with the operation of the tracker.

[0036] In the embodiment, the base 1 is provided with a plurality of upward extending lightening grooves, forming a hollow design, realizing the lightweight design of the bearing seat.

[0037] In the embodiment, the base 1 is made of aluminum. The base 1 is processed by die casting process of aluminum material, which is light in weight, high in strength, easy to process and cast, can form a relatively complex shape structure, is corrosion resistant, resistant to ultraviolet rays, and has less influence on its performance at high and low temperatures, thereby prolonging the service life of the bearing seat.

[0038] In the embodiment, the upper cover 2 is processed by stamping process of zinc-aluminum-magnesium steel material, which is easy to process and can be made of a single plate with simple shape. The upper cover 2 is light in weight, high in strength, and has good high and low temperature resistance due to the corrosion resistance of zinc-aluminum-magnesium material, thereby prolonging the service life of the bearing seat.

[0039] In the embodiment, the bearing 3 is different from the conventional structure, and is composed of two symmetrical half-ring bodies instead of an inner ring and an outer ring. The outer edges of the two half-ring bodies are spherical surfaces, and the inner walls of the two half-ring bodies are straight-angled bent grooves. The bent grooves of the two half-ring bodies are jointly embedded with an assembly (a detection square tube is embedded in the drawing, which is used for size test before assembly). The two half-ring bodies are designed in a two-half mode, which is convenient for assembly and replacement without disassembling the upper cover after damage. Gaps are arranged between the two ends of the two half-ring bodies. The gaps are used for installation misalignment and deformation space.

[0040] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
