DETAILED DESCRIPTION

[0032] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0033] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the present invention should be understood by people with ordinary skills in the field to which the present invention belongs. The "first", "second" and similar words used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

"Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0034] At present, the existing main shaft usually adopts a square tube structure. Since the four sides of the square tube are perpendicular to each other, the stress at the top corner of the plastic inner ring used to fix the square tube is relatively large, which can easily cause the plastic bearing to crack during long-term use.

[0035] In the optional embodiment 1, please refer to Figures 1 to 3 As shown, a mounting assembly for a photovoltaic tracking bracket provided by the present invention includes: a base 1, a photovoltaic main shaft 2, a first arc-shaped bearing 3 and a second arc-shaped bearing 4.

[0036] The base 1 has a bearing slot 11 that penetrates the base 1. The bearing slot 11 is circular; the base 1 is made of metal material, such as high-strength metal materials such as aluminum alloy and stainless steel.

[0037] The photovoltaic main shaft 2 is an octagonal column structure, and the photovoltaic main shaft 2 passes through the bearing slot 11 and is used to connect the photovoltaic panel. Among them, the stress of the octagonal photovoltaic main shaft 2 is relatively dispersed, so the octagonal photovoltaic main shaft 2 has good structural strength, which can effectively reduce the deformation of the photovoltaic main shaft 2 caused by the rotation torque and improve the service life of the photovoltaic main shaft 2.

[0038] The first arc-shaped bearing 3 is slidably mounted in the bearing slot 11 and can rotate along the inner wall of the bearing slot 11, and has a first clamping groove 31 that contacts the five end faces of the photovoltaic main shaft 2. Among them, the inner wall of the first arc-shaped bearing 3 is provided with a plurality of first weight-reducing grooves, which can reduce the weight of the first arc-shaped bearing 3 and can produce a certain amount of deformation, so as to facilitate the plugging and fixing of the photovoltaic main shaft 2; the first arc-shaped bearing 3 can be made of plastic material, and the first arc-shaped bearing 3 made of plastic material can absorb a certain impact force, and the structure is light in weight.

[0039] The second arc-shaped bearing 4 is slidably mounted in the bearing slot 11 and can rotate along the inner wall of the bearing slot 11, and has a second clamping groove 41 that contacts the five end faces of the photovoltaic main shaft 2. Among them, the inner wall of the second arc-shaped bearing 4 is provided with a plurality of second weight-reducing grooves, which can reduce the weight of the second arc-shaped bearing 4 and can produce a certain amount of deformation, so as to facilitate the plugging and fixing of the photovoltaic main shaft 2; the second arc-shaped bearing 4 can be made of plastic material, and the second arc-shaped bearing 4 made of plastic material can absorb a certain impact force, and the structure is light in weight.

[0040] The first clamping groove 31 and the second clamping groove 41 are combined to form a clamping groove for clamping the eight end faces of the photovoltaic main shaft 2. The two ends of the first clamping groove 31 and the second clamping groove 41 are located on the same end face, and the clamping groove is octahedral, which can effectively improve the structural strength of the clamping groove, reduce the torque generated by the rotation of the photovoltaic main shaft 2, avoid deformation of the clamping groove due to excessive torque, and improve the service life of the plastic bearing.

[0041] Specifically, the present invention splits the photovoltaic plastic bearing into a first arc bearing 3 and a second arc bearing 4. The first arc bearing 3 and the second arc bearing 4 adopt a split design and are combined to form a double-sided step structure, thereby changing the prior art in which the plastic bearing is installed first and the photovoltaic main shaft 2 is installed later. The problem of low efficiency in installing the photovoltaic main shaft 2 due to the small assembly gap is changed. The present invention allows the photovoltaic main shaft 2 to be installed in the base 1 first and then the plastic bearing is installed. The clamping groove of the plastic bearing is clamped on the photovoltaic main shaft 2 and laterally pushed into the base 1. The other end is connected by a buckle or bolt to form a double-step limit, which changes the installation method of the photovoltaic main shaft 2, reduces the installation difficulty of the photovoltaic main shaft 2, and improves the installation efficiency of the photovoltaic main shaft 2. At the same time, the photovoltaic main shaft 2 adopts an octagonal column structure, which can effectively improve the structural strength of the photovoltaic main shaft 2, the first arc bearing 3 and the second arc bearing 4, and increase the service life of the photovoltaic main shaft 2 and the plastic bearing.

[0045] Specifically, this embodiment avoids the first arc bearing 3 and the second arc bearing 4 from falling off from the other side of the base 1 during rotation by adding the first limiting step 33 and the second limiting step 43, thereby ensuring the stability and reliability of the operation of the photovoltaic tracking system.

[0047] Specifically, in this embodiment, the first arc bearing 3 and the second arc bearing 4 are respectively connected to the first limit step 2 33 and the second limit step 2 43 by snapping, which is convenient for assembling the inner ring of the plastic bearing, reduces the difficulty of installing the photovoltaic main shaft 2, improves the installation efficiency of the photovoltaic main shaft 2, and the first limit step 2 33 and the second limit step 2 43 are not easy to fall off, which solves the problem of loosening and failure of traditional bolt connections, and ensures the stability and reliability of the operation of the photovoltaic tracking system.

[0048] As an optional embodiment 2, please refer to Figure 5 As shown, in order to further improve the service life of the installation assembly for the photovoltaic tracking bracket, the first arc bearing 3 and the first limiting step 1 32 adopt an integrally formed structure, the first arc bearing 3 and the first limiting step 2 33 adopt a split structure, the first arc bearing 3 is connected to the first limiting step 2 33 by snap-fitting, and the second arc bearing 4 and the second limiting step 1 42 and the second limiting step 2 43 adopt an integrally formed structure.

[0049] Specifically, this embodiment improves the structural strength of the second arc bearing 4 by designing the second arc bearing 4, the second limiting step 1 42, and the second limiting step 2 43 as an integrally formed structure, so that the second arc bearing 4 can withstand more loads, and further improves the service life of the installation assembly for the photovoltaic tracking bracket.

The photovoltaic main shaft 2 adopts an octahedral structure, and the baffle plate 301 conflicts with one side end face of the photovoltaic main shaft 2, thereby reducing the deflection force generated by the conflict between the first limiting step 2 33 and the second limiting step 2 43, so that the limiting bolt 303 is rotated under force, thereby avoiding the rotation failure of the limiting bolt 303 and improving the service life of the installation assembly for the photovoltaic tracking bracket.
