Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic power generation technology, and in particular relates to a flexible tracking bracket side column rotating beam structure. Background Technology

[0002] With the continuous maturation of technology and the gradual reduction of costs, flexible photovoltaic brackets have been widely used in many scenarios such as mountainous agricultural-solar complementary projects, fishery-solar complementary projects, coastal mudflats, desertification control, and industrial and commercial distributed photovoltaic projects. This has led to a trend of replacing traditional fixed brackets in most scenarios. In the future, with further technological innovation and the continuous growth of market demand, flexible photovoltaic brackets are expected to be more widely used and developed.

[0003] However, flexible tracking supports and rigid tracking supports differ in their rotational force distribution. Rigid tracking supports only bear a negligible axial force, while the force distribution of flexible tracking supports, after losing rigid support, shifts to the two side columns and the slewing support structure of the inclined beam. The slewing support structure, composed of the rotating shaft, bearings, and support base, needs to bear the weight of the frame itself, as well as external wind and snow loads. At the same time, because the flexible steel cable is flexible, it needs to be pre-tightened during installation, so the slewing support structure also needs to bear the traction force brought about by the pre-tightening of the flexible steel cable. Therefore, designing a structure that is resistant to tension and torsion, and can also achieve stable rotational motion, is a problem that needs to be solved. Utility Model Content

[0004] The main technical problem to be solved by this utility model is to provide a flexible tracking bracket side column rotating beam structure with reasonable structure, good tensile and torsional resistance, and stable rotational motion.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A flexible tracking bracket side column rotating beam structure includes a side inclined beam, which is rotatably connected to a support base by two sliding bearings. The two sliding bearings are respectively fixed at the upper part of the support base near its two ends. Both sliding bearings are fixed by a fixing component. The support base is fixed to the upper end of the column.

[0007] The following are further optimizations of the above technical solution by this utility model:

[0008] The support base includes a base plate, and two support plates are fixed to the top surface of the base plate. The two support plates are arranged at a certain distance apart. A first support plate and a first baffle are fixed to one end of the two support plates. A second support plate and a second baffle are fixed to the other end of the two support plates. U-shaped grooves are opened on both the first baffle and the second baffle.

[0009] Further optimization: The two support plates, together with the first support plate and the first baffle, form the first bearing housing. The first bearing housing and its corresponding sliding bearing are fixedly connected by a fixing component. One side of the inclined beam of the sliding bearing contacting the first bearing housing protrudes beyond the end face of the first bearing housing. The height of the sliding bearing matches that of the first bearing housing.

[0010] Further optimization: The two support plates, together with the second support plate and the second baffle, form the second bearing housing. The second bearing housing and its corresponding sliding bearing are fixedly connected by a fixing component. One side of the inclined beam of the sliding bearing contacting the second bearing housing protrudes beyond the end face of the second bearing housing. The height of the sliding bearing and the second bearing housing are matched.

[0011] Further optimization: The fixing component includes two fixing seats, which are respectively fixed to the two support plates on opposite sides. A fixing element is detachably fixed above the two fixing seats by bolts and locking nuts.

[0012] Further optimization: The inclined beam includes an inclined beam frame, and a first rotating shaft is fixedly connected to the inclined beam frame near the first bearing housing. The first rotating shaft is rotatably connected to its corresponding sliding bearing.

[0013] Further optimization: A second rotating shaft is fixedly connected to the inclined beam frame near the second bearing housing, and the second rotating shaft is rotatably connected to its corresponding slider bearing.

[0014] Further optimization: The material of the sliding bearing is ultra-high molecular weight polyethylene. Its structure is either an integral bearing with a central opening or a bearing divided into two halves with arc-shaped grooves. The shape of the opening or the arc-shaped groove matches the shape of the first rotating shaft and the second rotating shaft, respectively.

[0015] Through rational design, this utility model structure not only improves the load-bearing capacity of the inclined beam, but also enhances the tensile and torsional resistance of the structure, ensuring that the structure can maintain good comprehensive mechanical performance under high load conditions and operate stably for a long time. The slider bearing has the characteristics of pressure resistance, self-lubrication, salt and alkali resistance, corrosion resistance, aging resistance, and impact resistance, meeting the application requirements of flexible tracking brackets and ensuring that photovoltaic modules can work stably.

Detailed Implementation

[0023] like Figure 1-5 As shown, a flexible tracking bracket side column rotating beam structure includes a side inclined beam 4, which is rotatably connected to a support base 1 by two sliding bearings 2. The two sliding bearings 2 are respectively fixed at the upper part of the support base 1 near its two ends, and both sliding bearings 2 are fixed by a fixing component 3. The support base 1 is fixed to the upper end of the column 5.

[0024] This design not only improves the load-bearing capacity of the inclined beam 4, but also enhances the tensile and torsional resistance of the structure, and ensures that the structure can achieve stable rotational motion.

[0025] The slider bearing 2 is made of ultra-high molecular weight polyethylene material, which has the characteristics of pressure resistance, self-lubrication, salt and alkali resistance, corrosion resistance, aging resistance and impact resistance, meeting the application requirements of flexible tracking bracket.

[0026] The support base 1 includes a base plate 101. Two support plates 102 are fixedly connected to the top surface of the base plate 101. The two support plates 102 are arranged at a certain distance apart. A first support plate 103 and a first baffle 104 are fixedly connected to one end of the two support plates 102. A second support plate 106 and a second baffle 107 are fixedly connected to the other end of the two support plates 102.

[0027] The upper surfaces of the first baffle 104 and the second baffle 107 are each provided with a U-shaped groove. The U-shaped groove serves to assist in supporting the inclined beam 4. The first baffle 104 bears the axial force transmitted from the pre-tensioned flexible steel cable 6 through the corresponding installed sliding bearing 2.

[0028] The support plate 102 has a first mounting groove 1021 and a second mounting groove 1022 at its two ends, respectively.

[0029] The two ends of the first tray 103 are respectively inserted into the corresponding first mounting slots 1021.

[0030] The two ends of the second tray 106 are respectively inserted into the corresponding second mounting slots 1022.

[0031] This design increases the strength of the support base 1 and improves the installation accuracy of the first support plate 103 and the second support plate 106.

[0032] The support base 1 is made of steel plates processed and spliced ​​together, which greatly improves the strength of the support base 1 and reduces the production cost of the support base 1.

[0033] Two support plates 102 together with the first support plate 103 and the first baffle 104 form a first bearing housing 105. The first bearing housing 105 is fixedly connected to the corresponding sliding bearing 2. One side of the sliding bearing 2 contacts the inclined beam 4 and protrudes out of the end face of the first bearing housing 105. The height of the sliding bearing 2 matches that of the first bearing housing 105.

[0034] With this design, the first support plate 103 provides effective support for the slider bearing 2, and the support plate 102 and the first baffle 104 define the radial and axial positions of the slider bearing 2.

[0035] Two support plates 102 together with the second support plate 106 and the second baffle 107 form a second bearing housing 108. The second bearing housing 108 is fixedly connected to the corresponding sliding bearing 2. One side of the sliding bearing 2 contacts the inclined beam 4 and protrudes out of the end face of the second bearing housing 108. The height of the sliding bearing 2 matches that of the second bearing housing 108.

[0036] With this design, the second support plate 106 provides effective support for the other slider bearing 2, and the support plate 102 and the second baffle 107 define the radial and axial positions of the other slider bearing 2.

[0037] Two sliding bearings 2 are respectively installed in the first bearing housing 105 and the second bearing housing 108.

[0038] Two fixing components 3 are used to fix the two slider bearings 2 into the first bearing housing 105 or the second bearing housing 108 respectively.

[0039] The fixing component 3 includes two fixing seats 109, which are respectively fixed to the two support plates 102 on opposite sides. The fixing component 301 is detachably fixed above the two fixing seats 109 by bolts 302 and locking nuts 303, which facilitates the installation and removal of the slider bearing 2.

[0040] The top surface of the fixing seat 109 is lower than the top surface of the slider bearing 2, facilitating the fixation of the slider bearing 2 in the bearing chamber by the fixing member 301.

[0041] The cross-sectional shape of the fixing member 301 is in a "C" shape structure, thus increasing the strength of the fixing member 301.

[0042] Except for this embodiment, the cross-sectional shape of the fixing member 301 can also be any reasonable shape that does not interfere with other parts.

[0043] The fixing member 301 is cut from a channel steel, thus reducing the manufacturing cost of the fixing member 301.

[0044] The side inclined beam 4 includes an inclined beam framework 401, which is spliced by rectangular pipes and angle steels.

[0045] A first rotating shaft 402 is fixedly connected to the inclined beam framework 401 near the position of the first bearing chamber 105, and the first rotating shaft 402 is rotatably connected to the corresponding slider bearing 2.

[0046] A second rotating shaft 403 is fixedly connected to the inclined beam framework 401 near the position of the second bearing chamber 108, and the second rotating shaft 403 is rotatably connected to the corresponding slider bearing 2.

[0047] With this design, it is ensured that the inclined beam framework 401 can swing smoothly back and forth around the axes of the first rotating shaft 402 and the second rotating shaft 403, and the stability of the inclined beam framework 401 during movement is ensured, improving the tensile and torsional resistance of the structure.

[0048] The structure of the sliding bearing 2 is an integral bearing with a central hole or a bearing divided into two halves with an arc-shaped groove, and the shape of the hole or arc-shaped groove respectively matches the outer shape of the first rotating shaft 402 and the second rotating shaft 403.

[0049] During use, the support seat 1 is fixedly installed on the column 5, the two sliding bearings 2 are respectively rotatably connected to the first rotating shaft 402 and the second rotating shaft 403 of the side inclined beam 4, then placed correspondingly into the first bearing chamber 105 and the second bearing chamber 108, the two fixing members 301 are placed correspondingly on the sliding bearings 2, and the bolt mounting holes of the two fixing members 301 are respectively aligned with the bolt mounting holes of the fixing seat 109. The bolts 302 are sequentially passed through the bolt mounting holes provided in the corresponding fixing members 301 and the fixing seat 109, and fixed with locking nuts 303. At this time, the two fixing members 301 respectively fix and install the two sliding bearings 2 on the support seat 1, and at the same time, the side inclined beam 4 is rotatably connected to the support seat 1.

[0050] Flexible steel cables 6 are installed at both ends of the inclined beam frame 401 via steel cable anchors 7. This structure is used in pairs. The flexible steel cables 6 are installed between the two inclined beam frames 401, and the photovoltaic modules 8 are installed on the flexible steel cables 6. The steel cable anchors 7 are adjusted to tighten the flexible steel cables 6 to ensure the stable operation of the photovoltaic modules 8. This structure further ensures the stable operation of the photovoltaic modules 8 through its excellent tensile and torsional resistance as well as its flexible and stable rotation capability.

[0051] Figure 5 The direction of the middle arrow is the direction of tension of the flexible steel cable 6, which is the direction of force on the inclined beam frame 401.

[0052] For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of this utility model, based on the teachings of this utility model, still fall within the protection scope of this utility model.
