Description

TECHNICAL FIELD

[0001] The utility model relates to photovoltaic technology field especially relates to a photovoltaic tracking support spherical bearing seat. BACKGROUND

[0002] In the photovoltaic panel use process, often need to use support to support it, and due to the matching relationship of photovoltaic panel and solar radiation direction, usually set up bearing seat to adjust the rotation angle of photovoltaic panel in real time, to achieve tracking support effect. Specifically, the bearing seat is the main connecting component of the main shaft of tracking support and column, and is also the base of the rotation movement of the main shaft. In some photovoltaic panel use environment, the column needs to be installed on the ground with a certain slope instead of flat ground, so there will be an angle between the main shaft and the column. Accordingly, the bearing seat needs to have a certain angle adjustment function to adapt to the angle adjustment of the main shaft and the column on the sloping ground. One kind of bearing seat in the prior art is a cylindrical bearing seat, that is, the direction of the main shaft rotation axis is collinear with the direction of the bearing seat axis, but the direction of the main shaft rotation axis is not adjustable. Therefore, the adjustment effect is limited, and it is only suitable for terrain with small slope. Another is a spherical bearing seat, that is, the direction of the main shaft rotation axis is adjustable, but it is not collinear with the axis of the bearing seat. The bearing seat is mostly a complete closed loop. The spherical bearing needs to be installed in the bearing seat before the main shaft can be installed. The gap between the spherical bearing and the main shaft is very small, which makes the installation of the main shaft difficult and reduces the installation efficiency.

Therefore, how to ensure that the bearing seat has a large adjustment angle on the sloping ground, has good transmission stability, is convenient for the installation of the main shaft, and improves the installation efficiency is a problem that needs to be solved in the field.

[0048] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar notations represent the same or similar parts or parts having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0049] In the description of the present application, unless explicitly defined and limited, the terms "connected", "connected", "fixed" should be understood broadly, for example, it can be fixedly connected, can be detachably connected, can be mechanically connected, can be electrically connected, can be directly connected, can be indirectly connected through an intermediate medium, can be the internal communication of two elements or the interaction relationship between two elements. For ordinary skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

First feature is in second feature "under", "below" and "under" include first feature is in second feature directly below and obliquely below, or just indicate first feature horizontal height is less than second feature.

[0051] In the use of photovoltaic panel, often need to use support to support it, and due to the matching relationship between photovoltaic panel and the sun irradiation direction, usually provided with bearing seat to adjust the rotation angle of photovoltaic panel in real time, so as to achieve tracking support effect. Specifically, the bearing seat is the main connecting component of the main shaft of the tracking support and the column, and is also the base of the rotation movement of the main shaft. In some photovoltaic panel using environment, the column needs to be installed on the ground with a certain slope instead of flat ground, so that there will be an angle between the main shaft and the column. Correspondingly, the bearing seat needs to have a certain angle adjustment function to adapt to the adjustment of the main shaft and the column on the slope. A bearing seat in the prior art is a cylindrical bearing seat, that is, the direction of the main shaft rotation axis is collinear with the direction of the bearing seat axis, but the direction of the main shaft rotation axis is not adjustable. Therefore, only the fine adjustment of the position of the bearing seat on the column can be used to adapt to the slope terrain, and the adjustment effect is limited, and it is only suitable for terrain with small slope. Another is a spherical bearing seat, that is, the direction of the main shaft rotation axis is adjustable, but not collinear with the direction of the bearing seat axis. The bearing seat is mostly a complete closed loop, and the spherical bearing needs to be installed in the bearing seat before the main shaft can be installed. The gap between the spherical bearing and the main shaft is very small, which brings great difficulty to the installation of the main shaft, reduces the installation efficiency, and affects the transmission stability and reliability of the spherical surface made of sheet metal stamping. Therefore, how to ensure that the bearing seat has a large adjustment angle on the slope, has good transmission stability, is convenient for the installation of the main shaft, and improves the installation efficiency is a problem to be solved by the personnel in the field.

[0052] The technical scheme of the embodiment will be further described below in combination with the drawings and through specific embodiments.

[0053] As Figures 1-18The embodiment shown provides a photovoltaic tracking support spherical bearing seat. The photovoltaic tracking support spherical bearing seat in the embodiment comprises a support seat 10, a bearing seat 20, a bearing shell 30 and a spherical bearing 40. The support seat 10 is adjustably connected to a stand 200. The bearing seat 20 comprises a lower bearing seat 21 and an upper bearing seat 22. The lower bearing seat 21 is installed on the support seat 10. The upper bearing seat 22 is provided with a lug portion 222. A fixing member limits and fixes the upper bearing seat 22 in the lower bearing seat 21 through the lug portion 222. The bearing seat 20 is sleeved outside the bearing shell 30. The bearing shell 30 comprises a lower bearing shell 31 and an upper bearing shell 32 which are detachably connected. The bearing shell 30 is sleeved outside the spherical bearing 40 and connected with the spherical bearing 40 through a spherical surface. The spherical bearing 40 is provided in a split structure and is sleeved outside a main shaft 100 of a photovoltaic tracking support.

[0054] Specifically, the support seat 10 is adjustably arranged on the stand 200, so that the support seat 10 can be finely adjusted to better adapt to a sloping land. Further, the bearing seat 20, the bearing shell 30 and the spherical bearing 40 are all provided in a split structure, so that the problem of too small gap between the bearing and the main shaft 100 in the prior art and inconvenient installation can be avoided, and the spherical bearing 40, the bearing shell 30 and the bearing seat 20 can be quickly disassembled and assembled. Specifically, the spherical bearing 40 and the bearing shell 30 are connected through a spherical surface, so that the photovoltaic panel on the main shaft 100 can be synchronously rotated towards the sun, and the main shaft 100 can be adjusted by a large deflection angle, so as to adapt to the slope of the sloping land and improve the utilization rate and the application range of the device. Optionally, the upper bearing seat 22 in the bearing seat 20 is provided with a lug portion 222. A fixing member limits and fixes the upper bearing seat 22 in the lower bearing seat 21 through the lug portion 222, so as to realize detachable connection of the two. The lug portion 222 facilitates quick installation of the fixing member. On the other hand, the photovoltaic tracking support spherical bearing seat in the embodiment can quickly disassemble and assemble the bearing seat 20, the bearing shell 30 and the spherical bearing 40, and improve quick installation of the device on the stand 200 and the main shaft 100 in the spherical bearing 40, so that the photovoltaic tracking support on the sloping land can be adjusted by a large angle to adapt to use of the photovoltaic panel on the sloping land.

[0055] The specific structure of the photovoltaic tracking support spherical bearing seat in the embodiment will be described below.

[0056] As Figures 1 to 6As shown, the spherical bearing seat of the photovoltaic tracking support in the embodiment is arranged on the column 200 and is arranged in one-to-one correspondence with the column 200, and the main shaft 100 is arranged in the plurality of photovoltaic tracking support spherical bearing seats to realize multi-point support and ensure stability in use. Further, the plurality of columns 200 are sequentially placed at different heights of the slope, and the main shaft 100 is adapted to the slope of the slope under the rotating effect of the photovoltaic tracking support spherical bearing seat, thereby ensuring stable support of the photovoltaic panel. Exemplarily, the plurality of columns 200 are arranged along the north-south direction, so that the main shaft 100 is also placed along the north-south direction after installation, thereby ensuring that the photovoltaic panel is placed towards the sun and can rotate in the east-west direction. Specifically, the photovoltaic tracking support spherical bearing seat in the embodiment includes a support seat 10, a bearing seat 20, a bearing shell 30, a spherical bearing 40, a fixing member and a fastener. Optionally, the bearing seat 20 includes a detachably connected lower bearing seat 21 and an upper bearing seat 22, the bearing shell 30 includes a detachably connected lower bearing shell 31 and an upper bearing shell 32, and the spherical bearing 40 is arranged in a split structure. Thus, under the split arrangement of the three, not only is rapid disassembly and assembly facilitated, but the installation efficiency of the main shaft 100 is improved and the installation period is saved. Exemplarily, the lower bearing seat 21 and the upper bearing seat 22 are connected by the fixing member, and the lower bearing shell 31 and the lower bearing seat 21 are fixed to the support seat 10 by the fastener.

[0057] Specifically, the support seat 10 is adjustably connected to the column 200. In the embodiment, when the column 200 is arranged along the north-south direction, the support seat 10 can be positionally adjusted along the vertical Z direction, and the lower bearing shell 31 and the lower bearing seat 21 can be positionally finely adjusted along the east-west direction on the support seat 10 through the long waist hole 112 of the support seat 10, thereby improving the position change range of the main shaft 100 and improving the installation adaptability and structural stability of the main shaft 100. Specifically, the lower bearing seat 21 is installed on the support seat 10, the bearing seat 20 is sleeved on the outside of the bearing shell 30, the bearing shell 30 is sleeved on the outside of the spherical bearing 40, the spherical bearing 40 is sleeved on the outside of the main shaft 100 of the photovoltaic tracking support, and the bearing shell 30 and the spherical bearing 40 are connected by a spherical surface, thereby realizing multi-angle rotation and deflection of the main shaft 100 on the photovoltaic tracking support spherical bearing seat and better adapting to installation of the photovoltaic panel on the slope.

[0058] As Figure 7As shown, specifically, the support base 10 comprises a support plate 11 and a connecting plate 12, and the support plate 11 is provided with a first flange 111 and a long waist hole 112, and the connecting plate 12 is provided with a second flange 121 and a locking hole 122. Optionally, two connecting plates 12 are respectively arranged at both ends of the support plate 11, and are both arranged perpendicular to the support plate 11, and the two connecting plates 12 can be installed on the column 200 through bolts. Further, the support plate 11 is extended with the first flange 111 on both sides thereof in a direction away from the connecting plate 12, so as to improve the structural rigidity. Optionally, the support plate 11 is provided with the long waist hole 112 along the length direction thereof, and in the embodiment, two long waist holes 112 are provided, so that when the lower bearing seat 21 is installed on the support plate 11, the length direction of the long waist hole 112 can be adjusted, and then the displacement fine adjustment of the main shaft 100 in the east-west direction is realized.

[0059] Similarly, the connecting plate 12 is extended with the second flange 121 on both sides thereof in a direction away from the column 200, so as to improve the structural rigidity. Optionally, a plurality of locking holes 122 are arranged on the connecting plate 12 in an interval, and every two locking holes 122 are arranged as a group, and the plurality of groups of locking holes 122 are arranged on the connecting plate 12 in an interval. Exemplarily, in the embodiment, six groups of locking holes 122 are provided, so that after the bolts are arranged through the locking holes 122, the support base 10 is fixed on the column 200, and the connecting height of the support base 10 can be adjusted according to the needs, and then the adjustment of the main shaft 100 at different heights relative to the ground is realized, so as to be compatible with the pile foundation position error and adapt to the installation on the slope. Exemplarily, the support plate 11 and the connecting plate 12 can be arranged as an integrated structure.

[0060] In combination Figure 5 , Figures 8-9 As shown, in the embodiment, the lower bearing seat 21 comprises a bottom plate 211 and a side plate 212, and the bottom plate 211 is provided with a connecting hole 2111, and the side plate 212 is provided with a fixing hole 2121. Specifically, the bottom plate 211 is arranged on the support plate 11, and the lower bearing seat 21 is installed on the support base 10 by arranging the fastener through the connecting hole 2111 and the long waist hole 112. Optionally, the fixing hole 2121 is arranged as a circular hole, so as to ensure the connection stability. Further, the side plate 212 is arranged in two, and the two side plates 212 are arranged on the opposite sides of the bottom plate 211, so as to form an accommodating space by surrounding, and facilitate the installation of the lower bearing shell 31, and provide axial and radial support for the lower bearing shell 31. In the embodiment, the side plate 212 is arranged as an arc-shaped structure, for supporting the lower bearing shell 31 and being capable of limiting the axial position of the lower bearing shell 31. Further, the two ends of the side plate 212 are provided with the fixing hole 2121 for the fixing member to be arranged through the connecting hole.

[0061] It is worth noting that the photovoltaic panel is usually used in the desert area, and there is a strong wind in the desert area all the year round. If the structure strength of the lug portion 222 is not enough, the lug portion 222 is easily straightened by the wind blowing the photovoltaic panel, thereby causing the connection to fail, and further causing the entire device to malfunction.

[0062] Therefore, in order to solve the above problems, the lug portion 222 is integrally formed with a lug reinforcing rib 2221 in the middle portion, thereby being capable of significantly improving the structure strength of the lug portion 222.

[0063] Further, the side plate 212 is provided with a side stop edge 2122, which can be close to the outer side of the lug portion 222 to support the lug portion 222. In this way, the lug portion 222 is supported and protected by the side stop edge 2122. Specifically, the two side stop edges 2122 at the same position of the two side plates 212 are oppositely arranged to better support the two opposite sides of the lug portion 222.

[0064] In combination with Figure 2 and Figure 10 As shown in , the upper bearing seat 22 includes a seat body portion 221 and a lug portion 222, the seat body portion 221 is provided with a limiting stop edge 2211, and the inner side thereof is provided with a first cylindrical surface 201. Specifically, the seat body portion 221 is arranged in an arc-shaped structure, the arc degree of which is adapted to the arc degree of the side plate 212, and the inner side surface of the seat body portion 221 is arranged as a cylindrical surface, i.e., the first cylindrical surface 201, to ensure the installation stability of the bearing shell 30 in the bearing seat 20. Alternatively, the two sides of the seat body portion 221 are bent toward the inner side surface thereof to form the limiting stop edge 2211 for limiting the upper bearing shell 32, so as to avoid disengagement of the upper bearing shell 32 in the bearing seat 20. Further, the seat body portion 221 is extended at both ends and bent to form the lug portion 222 with a hook-shaped structure. In the embodiment, the upper end of the lug portion 222 is open and the two sides are throughly arranged. The fixing member limits and fixes the upper bearing seat 22 in the lower bearing seat 21 through the lug portion 222, so as to realize the detachable connection between the upper bearing seat 22 and the lower bearing seat 21. As shown in Figure 2 When the upper bearing seat 22 is installed, the lug portion 222 thereof is placed between the two side plates 212, so that the through passages at both ends of the lug portion 222 are communicated with the fixing holes 2121. After the fixing member is threaded through one fixing hole 2121, it is threaded through the through passage and abuts against the side wall of the through passage, i.e., the inner side of the lug portion 222, and then threaded through the other fixing hole 2121, so as to limit and fix the upper bearing seat 22 in the lower bearing seat 21. Exemplarily, the fixing member is arranged as a bolt, which can be locked by a nut after being threaded.

[0065] As shown in Figures 11-13As shown, one of the lower bearing housing 31 and the upper bearing housing 32 is provided with an insert block 321, and the other is provided with a slot 311 that mates with the insert block 321. This allows for a detachable connection between the lower bearing housing 31 and the upper bearing housing 32 through the insertion of the insert block 321 into the slot 311, ensuring a tight connection, radial limiting, and improved transmission stability. Exemplarily, in this embodiment, the lower bearing housing 31 is provided with a slot 311, and the upper bearing housing 32 is provided with an insert block 321. Both the slot 311 and the insert block 321 are cylindrical to ensure that the insert block 321 can be securely engaged in the slot 311 and is not easily dislodged. In other embodiments, the slot 311 and the insert block 321 may also be trapezoidal.

[0066] Combination Figure 12 and Figures 14-15 As shown, the lower bearing housing 31 is provided with an arc-shaped structure, and a first step 312 extends from both sides of the arc-shaped structure. A first abutment surface 3121 is provided on the outer side of the first step 312, and a first concave spherical surface 301 is provided on the inner side of the lower bearing housing 31. A mounting hole 313 is provided through the first concave spherical surface 301. Specifically, when the lower bearing housing 31 is installed on the lower bearing seat 21, the first step 312 abuts against the side plate 212 of the lower bearing seat 21, and its first abutment surface 3121 abuts against the side plate 212, thereby confining the main body of the lower bearing housing 31 located between the two first steps 312 within the two side plates 212 of the lower bearing seat 21, thereby achieving axial positioning of the lower bearing housing 31 on the lower bearing seat 21. Furthermore, the lower bearing housing 31 is installed on the base plate 211 of the lower bearing seat 21 and sandwiched between the two side plates 212, that is, placed in the receiving space. At this time, the mounting hole 313 is connected to the connecting hole 2111. Fasteners are sequentially passed through the mounting hole 313 and the connecting hole 2111 to install the lower bearing housing 31 on the base plate 211.

[0067] like Figure 12 As shown, exemplarily, the mounting hole 313 is a countersunk hole, and the depth of its upper countersunk groove can be set as needed. This ensures that after the fastener is installed, it will not affect the installation of the ball bearing 40 in the bearing housing 30, nor will it interfere with the rotation of the ball bearing 40. Exemplarily, the fastener is a bolt, and the width of the countersunk groove is slightly larger than the bolt end size, thereby confining the bolt end within the countersunk groove, and allowing for position locking via the nut at the bolt tail.
