Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and more particularly to an electrical equipment fixing device and a photovoltaic system. Background Technology

[0002] Photovoltaic systems typically require electrical equipment, such as power supply boxes, data acquisition components, and inverters, to meet the normal operation needs of the photovoltaic system, including power generation. Currently, electrical equipment is generally installed directly onto pile foundations using bolts or screws. This method of fixing requires a certain pile foundation height, especially in flood-prone areas. If the pile foundation is too low, floodwaters can easily submerge the electrical equipment, affecting the normal operation of the photovoltaic system. Therefore, when the pile foundation height of the photovoltaic system is low, an additional pile foundation is needed to install the electrical equipment, increasing production costs. To solve the above problems, some manufacturers install the electrical equipment on columns above the pile foundation. However, the main beam and rotary drive device are fixed on top of the column. In some application scenarios, the column height is low. If the electrical equipment is installed too high, it will interfere with the rotary drive device or the photovoltaic modules above the main beam, affecting the normal operation of the photovoltaic system. If the electrical equipment is installed too close to the bottom of the column, it will interfere with the pile foundation, making installation impossible. Utility Model Content

[0003] The purpose of this application is to provide an electrical equipment fixing device and a photovoltaic system that can not only prevent electrical equipment from being damaged by floods, but also prevent electrical equipment from interfering with pile foundations or photovoltaic modules.

[0034] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0035] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; or they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0036] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) are relative rather than absolute when describing the structure and movement of the various components, and are not intended to limit the direction of the product during actual use.

[0037] Furthermore, in the description of this application, ordinal numbers, such as "first" and "second," are used only to distinguish related objects and should not be construed as indicating or implying the relative importance or order between related objects.

[0038] According to the specific embodiments provided in this application, such as Figure 1 and Figure 2 As shown, an electrical equipment fixing device includes a connecting assembly 200 and a vertical support 100. The connecting assembly 200 includes a clamp 210, a connector 220, and a crossarm 230. The clamp 210 is used to connect to the column 10. One side of the connector 220 is connected to the clamp 210. The other side of the connector 220 is connected to one side of the crossarm 230. The vertical support 100 is used to connect the electrical equipment 20 and is connected to the other side of the crossarm 230.

[0039] In this embodiment, the vertical support 100 is fixedly connected to the electrical equipment 20. A mounting plate 21 is provided on the back of the electrical equipment 20. The vertical support 100 is a C-shaped steel structure. The vertical support 100 and the mounting plate 21 on the back of the electrical equipment 20 are fixedly connected by bolts. In some application scenarios, the vertical support 100 can also be fixedly connected to the mounting plate 21 by welding. The vertical support 100 is fixedly connected to the connecting assembly 200, that is, the vertical support 100 is fixedly connected to the photovoltaic support column 10 through the connecting assembly 200, so as to install the electrical equipment 20 on the column 10. The electrical equipment 20 includes, but is not limited to, inverters, combiner boxes, transformers, etc. The electrical equipment 20 is installed on the photovoltaic support column 10 through an electrical equipment fixing device. The column 10 is installed on the pile foundation 30, which allows the installation height of the electrical equipment 20 to be raised as much as possible, reducing the risk of damage to the electrical equipment 20 from flooding and leakage.

[0040] The connecting assembly 200 includes a clamp 210, a connector 220, and a crossbeam 230. The clamp 210 clamps the column 10, and the crossbeam 230 is connected to the clamp 210 through the connector 220. The connector 220 can increase the distance between the crossbeam 230 and the clamp 210, thereby increasing the distance between the electrical equipment 20 and the column 10 and the pile foundation 30. This can prevent the electrical equipment 20 from interfering with the rotary drive device 11 on the column 10 or with the photovoltaic modules above the main beam, and also prevent the electrical equipment 20 from interfering with the pile foundation 30 below the column 10. This not only allows the electrical equipment 20 to be installed normally, but also does not affect the normal operation of the photovoltaic support.

[0041] This embodiment does not limit the number of connecting components 200; there can be one or more connecting components 200. When there are multiple connecting components 200, they are spaced apart along the axial direction of the column 10. This embodiment also does not limit the specific number of vertical supports 100; there can be one or more vertical supports 100. When there is only one vertical support 100, the width of the vertical support 100 needs to be increased, and two or more mounting positions need to be provided on the vertical support 100 along the width direction. The vertical support 100 is connected to the crossarm 230 through two or more mounting positions to improve the connection strength between the vertical support 100 and the crossarm 230, thereby improving the installation stability of the electrical equipment 20. When there are multiple vertical supports 100, they are evenly or non-uniformly spaced along the direction perpendicular to the axial direction of the column 10 on the electrical equipment 20.

[0042] like Figure 2 As shown in Figure 2, the structural diagram shows that there are two connecting components 200 and two vertical supports 100. The two connecting components 200 are spaced apart along the axial direction of the column 10, and the two vertical supports 100 are spaced apart on the electrical equipment 20 along the direction perpendicular to the axial direction of the column 10. One end of each of the two cross supports 230 is connected to one vertical support 100, and the other end of each of the two cross supports 230 is connected to the other vertical support 100.

[0043] Two vertical supports 100 are symmetrically arranged on both sides of the column 10; two horizontal supports 230 are perpendicular or approximately perpendicular to the vertical supports 100, and the two ends of the two horizontal supports 230 are respectively fixedly connected to multiple vertical supports 100 to improve the connection strength between the horizontal supports 230 and the vertical supports 100. By setting multiple connecting components 200 and multiple vertical supports 100, the structural strength and load-bearing capacity of the entire electrical equipment fixing device can be improved, thereby improving the installation stability of the electrical equipment 20 and making it less prone to shaking after installation. Of course, in other embodiments, the number of connecting components 200 and vertical supports 100 can also be three or more. Figure 2 This is merely an example and does not constitute a limitation on the number of connecting components 200 and vertical supports 100. Optional, such as Figure 4 As shown, multiple bolt holes 110 can be provided on the vertical support 100 along the vertical direction. By adjusting the connection position between the crossbeam 230 and the bolt holes 110 on the vertical support 100, the installation height of the electrical equipment 20 can be adjusted to prevent the electrical equipment 20 from being damaged by flooding. When there are multiple vertical supports 100, the number and position of the bolt holes 110 on the multiple vertical supports 100 can be set accordingly or not. When not set accordingly, the number and position of the bolt holes 110 can be flexibly adjusted according to the actual project needs. The bolt holes 110 on the vertical support 100 are preferably elliptical holes to overcome machining errors and installation errors.

[0044] In some embodiments, such as Figure 5As shown, the connector 220 includes a connecting part 221, a first bent part 222, and a second bent part 223. The first bent part 222 is disposed on one side of the connecting part 221, and the second bent part 223 is disposed on the other side of the connecting part 221 and is disposed opposite to the first bent part 222. The first bent part 222 is connected to the clamp 210, and the second bent part 223 is connected to the crossbeam 230.

[0045] In this embodiment, as Figure 6 As shown, the clamp 210 is U-shaped, clamping the column 10 and fixing both ends to the first bend 222 of the connector 220. The clamp 210 can be fixedly connected to the first bend 222 by bolts. In some embodiments, the clamp 210 can also be fixedly connected to the first bend 222 by welding. The second bend 223 is fixedly connected to the crossarm 230 by multiple bolts. The connecting part 221 connects the first bend 222 and the second bend 223. The connecting part 221 can increase the distance between the crossarm 230 and the clamp 210, that is, increase the distance between the electrical equipment 20 and the column 10. In practical applications, the distance between the electrical equipment 20 and the column 10 can be adjusted by changing the width of the connecting part 221 so that the electrical equipment 20 does not interfere with the column 10 and the pile foundation 30.

[0046] In some embodiments, such as Figure 3 As shown, the crossarm 230 includes a vertical part 231, a first horizontal part 232 and a second horizontal part 233. The first horizontal part 232 and the second horizontal part 233 are respectively connected to the vertical part 231, and the first horizontal part 232 and the second horizontal part 233 are arranged opposite to each other along the width direction of the vertical part 231. The vertical part 231 is connected to the connector 220.

[0047] The first horizontal part 232 and the second horizontal part 233 are arranged perpendicularly or approximately perpendicularly to the vertical part 231. The vertical part 231 is fixedly connected to the second bent part 223 of the connector 220 by bolts. The first horizontal part 232 and the second horizontal part 233 can be fixedly connected to the vertical support 100 by bolts, so as to adjust the connection position between the cross support 230 and the vertical support 100, thereby adjusting the installation height of the electrical equipment 20.

[0048] Optional, such as Figure 2 and Figure 3 As shown, the vertical part 231 has multiple elliptical holes 2311 spaced along its length, and the connector 220 is fixedly connected to the elliptical holes 2311 by bolts. By making the bolt holes on the crossarm 230 elliptical, the installation position can be adjusted within a certain range, thereby overcoming machining and installation errors. Furthermore, the bolt holes on the crossarm 230 can also be oblong holes, allowing the connection position between the connector 220 and the crossarm 230 to be adjusted within a certain range.

[0049] Optional, such as Figure 3 As shown, the first horizontal portion 232 has an inwardly recessed first recess 2321; the second horizontal portion 233 has an inwardly recessed second recess 2331. The inward recess of the first recess 2321 can form a bending structure on the first horizontal portion 232, and the inward recess of the second recess 2331 can form a bending structure on the second horizontal portion 233, thereby increasing the strength of the first horizontal portion 232 and the second horizontal portion 233, and thus improving the installation stability.

[0050] Optional, such as Figure 3 As shown, the first horizontal portion 232 bends inward on the side away from the vertical portion 231 to form a third bend 2322, which is positioned opposite to the vertical portion 231. The second horizontal portion 233 bends inward on the side away from the vertical portion 231 to form a fourth bend 2332, which is positioned opposite to the vertical portion 231. Both the third bend 2322 and the fourth bend 2332 are L-shaped. The third bend 2322 on the first horizontal portion 232 further increases the strength of the first horizontal portion 232, and the fourth bend 2332 on the second horizontal portion 233 further increases the strength of the second horizontal portion 233, thereby increasing the overall strength of the crossarm 230 and improving the installation stability of the electrical equipment 20.

[0051] Optional, such as Figure 3 and Figure 7 As shown, the connecting assembly 200 also includes multiple steel clips 240. The steel clips 240 are disposed between the first horizontal portion 232 and the second horizontal portion 233, and engage with the third and fourth bent portions 2332 to limit the steel clips 240 within the crossbeam 230. The steel clips 240 have bolt holes, and the vertical support 100 is connected to the steel clips 240 by bolts. After the bolts are tightened, a fixed connection between the crossbeam 230 and the vertical support 100 is achieved. This embodiment does not limit the number of steel clips 240; the number of steel clips 240 can be set according to the number of vertical supports 100, with multiple steel clips 240 correspondingly connected to multiple vertical supports 100 to improve the connection stability between the crossbeam 230 and the vertical support 100. Since the crossarm 230 is relatively long, if the crossarm 230 is only connected to the vertical arm 100 by bolts, the connection strength will be insufficient. In this embodiment, the crossarm 230 is fixedly connected to the vertical arm 100 by setting a steel locking buckle 240, which can improve the connection strength between the crossarm 230 and the vertical arm 100.

[0052] This application also provides an embodiment of a photovoltaic system, including a photovoltaic bracket, electrical equipment 20, and an electrical equipment fixing device as described in any of the above embodiments. The structure of the electrical equipment fixing device is as follows: Figures 1 to 7As shown, the electrical equipment fixing device is installed on the column 10 of the photovoltaic support, and the electrical equipment 20 is connected to the vertical support 100 of the electrical equipment fixing device. This application adds a connector 220 between the crossarm 230 and the clamp 210 on the column 10, which increases the distance between the electrical equipment 20 and the column 10, effectively preventing interference between the electrical equipment 20 and the pile foundation 30 and the column 10. The vertical support 100 and the crossarm 230 are connected by bolts, and the number and position of the bolt holes 110 on the vertical support 100 can be flexibly adjusted to avoid the impact of floods and other conditions. Furthermore, the electrical equipment fixing device of this application has a stable structure, strong wind resistance, simple structure, and low cost.
