Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic components, in particular to a pressure-resistant protective structure of a photovoltaic power station. Background Art

[0002] A photovoltaic power station is a power generation system that utilizes solar energy and uses special materials such as crystalline silicon panels, inverters and other electronic components. It is connected to the power grid and transmits electricity to the grid. Currently, the photovoltaic panels of photovoltaic power stations are installed in open-air areas. When photovoltaic panels are used in the open air for a long time in winter, snow will accumulate on their surface, which can easily cause pressure on the surface of the photovoltaic panels and cause damage.

[0003] The utility model patent with patent authorization announcement number CN 219999321 U discloses a pressure-resistant protection structure for a photovoltaic power station, including a connecting frame, an installation cavity is opened inside the connecting frame, a first gear is rotatably connected to the inner wall of the installation cavity, a rotating rod is fixedly connected to the inner wall of the first gear, a motor is fixedly connected to the outer wall of the connecting frame, the output end of the motor is fixedly connected to one end of the rotating rod, a second gear is meshedly connected to the outer wall of the first gear, and a second rotating roller is fixedly connected to the inside of the second gear.

[0004] However, the above-mentioned compression protection structure still has some shortcomings in actual use. The most obvious one is that as the use time increases, the side of the brush plate close to the photovoltaic panel will gradually wear out, and as the degree of wear increases, the cleaning effect of the brush plate will continue to decline. At this time, the operator is required to remove the brush plate from the side of the transmission belt and replace it. The operation is cumbersome and time-consuming, and is not convenient in actual use.

[0005] Therefore, it is necessary to invent a pressure-resistant protective structure for a photovoltaic power station to solve the above problems. Utility Model Content

[0006] The utility model aims to provide a pressure-resistant protection structure for a photovoltaic power station. A cleaning mechanism is provided so that when the cleaning belt currently contacts the photovoltaic panel and the cleaning effect is reduced due to wear, the two locking bolts are successively loosened so that the two locking bolts respectively release the lock of the two rotating shafts, and then the two turntables are rotated. When the turntables are rotated, the rotating shafts are driven to rotate. The rotating shaft wound with the cleaning belt outputs the cleaning belt during rotation, and the other rotating shaft rewinds the cleaning belt during rotation. At this time, the cleaning belt originally located under the extension plate is moved away under the rewinding of the rotating shaft, and the unworn part moves to the underside of the extension plate. Then the two locking bolts can be tightened to solve the problem proposed in the above-mentioned background technology that as the use time increases, the side of the brush plate close to the photovoltaic panel will gradually wear out, and as the degree of wear increases, the cleaning effect of the brush plate will continue to decline. At this time, the operator is required to remove and replace the brush plate from the side of the transmission belt, which is cumbersome and time-consuming, and not convenient in actual use.

[0030] The present disclosure is further described in detail below in conjunction with the accompanying drawings and implementations. It is understood that the specific implementations described herein are only used to explain the relevant content, rather than to limit the present disclosure. It should also be noted that, for ease of description, only the parts related to the present disclosure are shown in the accompanying drawings.

[0031] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in the present disclosure can be combined with each other. The technical solution of the present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0032] Unless otherwise specified, the exemplary embodiments / embodiments shown will be understood as providing exemplary features of various details of some ways in which the technical concept of the present disclosure can be implemented in practice. Therefore, unless otherwise specified, the features of the various embodiments / embodiments can be combined, separated, interchanged and / or rearranged without departing from the technical concept of the present disclosure.

[0033] The use of cross-hatching and / or shading in the accompanying drawings is generally used to make the boundaries between adjacent components clear. As such, unless otherwise specified, the presence or absence of cross-hatching or shading does not convey or indicate any preference or requirement for the specific materials, material properties, dimensions, proportions, commonalities between the components shown, and / or any other characteristics, attributes, properties, etc. of the components. In addition, in the accompanying drawings, the sizes and relative sizes of the components may be exaggerated for clarity and / or descriptive purposes. When the exemplary embodiments can be implemented differently, the specific process sequence can be performed in a different order than described. For example, two successively described processes can be performed substantially simultaneously or in an order opposite to the described order. In addition, the same figure numbers represent the same components.

[0034] When a component is referred to as being "on" or "over," "connected to," or "coupled to" another component, the component may be directly on, directly connected to, or directly coupled to the other component, or intervening components may be present. However, when a component is referred to as being "directly on," "directly connected to," or "directly coupled to" another component, there are no intervening components. For this purpose, the term "connected" may refer to a physical connection, an electrical connection, etc., with or without intervening components.

[0035] For descriptive purposes, the present disclosure may use spatially relative terms such as "under," "beneath," "under," "down," "over," "upper," "above," "higher," and "side (e.g., as in "sidewall")," to describe the relationship of one component to another (other) component as shown in the accompanying drawings. The spatially relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the accompanying drawings. For example, if the device in the accompanying drawings is turned over, components described as "under" or "beneath" other components or features would subsequently be positioned "over" the other components or features. Thus, the exemplary term "under" can encompass both the "over" and "under" orientations. Furthermore, the device may be otherwise oriented (e.g., rotated 90 degrees or at other orientations), and the spatially relative descriptors used herein should be interpreted accordingly.

[0036] The terms used here are for the purpose of describing specific embodiments, and are not intended to be restrictive. As used here, unless the context clearly indicates otherwise, the singular forms "one (kind, person)" and "said (the)" are also intended to include plural forms. In addition, when the terms "comprise" and / or "include" and their variations are used in this specification, it is explained that there are stated features, integral bodies, steps, operations, parts, assemblies and / or their groups, but it is not excluded that there are or add one or more other features, integral bodies, steps, operations, parts, assemblies and / or their groups. It should also be noted that, as used here, the terms "substantially", "approximately" and other similar terms are used as approximate terms and not as degree terms, so that they are used to explain the inherent deviations of the measured values, calculated values ​​and / or the values ​​provided that will be recognized by those of ordinary skill in the art.

[0037] Figure 1 It is a schematic diagram of the overall structure of a compression protection structure of a photovoltaic power station according to an embodiment of the present disclosure.

[0038] like Figure 1-Figure 3 As shown, the compression protection structure of the photovoltaic power station disclosed in the present invention may include: a base plate 1, a bearing mechanism 2, a photovoltaic panel 3, a driving mechanism 4, a cleaning mechanism 5 and other components.

[0039] Figure 2 It is a structural schematic diagram of a bearing mechanism 2 of a compression protection structure of a photovoltaic power station according to an embodiment of the present disclosure.

[0040] like Figure 2 As shown, in a preferred embodiment, the supporting mechanism 2 includes a supporting plate 21, a mounting plate 22, a torsion spring 23, a support plate 24 and a moving wheel 25, wherein the supporting plate 21 is located at the top of the base plate 1, the photovoltaic panel 3 is fixedly arranged on the top of the supporting plate 21, the mounting plate 22 is located at one end of the side of the supporting plate 21 and is rotatably connected to the supporting plate 21 through a pin shaft, the torsion spring 23 is fixedly connected between the supporting plate 21 and the mounting plate 22, the support plate 24 is located at the other end of the side of the supporting plate 21 and is rotatably connected to the supporting plate 21 through a pin shaft, and the moving wheel 25 is rotatably connected to the support plate 24 through a pin shaft and contacts the base plate 1.

[0041] Therefore, when snow accumulates on the surface of the photovoltaic panel 3, the supporting plate 21 rotates under the action of gravity. During the rotation of the supporting plate 21, the bottom end of the supporting plate 24 moves backward on the top of the base plate 1 through the moving wheel 25. After the subsequent snow is cleared, the torsion spring 23 drives the supporting plate 21 to reset.

[0042] Figure 3 It is a schematic structural diagram of a driving mechanism 4 and a cleaning mechanism 5 of a pressure-resistant protection structure of a photovoltaic power station according to an embodiment of the present disclosure.

[0043] like Figure 3 As shown, in the present disclosure, the driving mechanism 4 includes a guide shell 41, a reciprocating screw 42, a driving motor 43, a movable slider 44 and an extension plate 45, wherein the guide shell 41 is fixedly arranged on the top of the supporting plate 21, the reciprocating screw 42 passes through the end of the guide shell 41 and extends to the inner side of the guide shell 41 and is rotatably connected to the guide shell 41 through a bearing, the driving motor 43 is fixedly arranged at the end of the guide shell 41 and is transmission-connected to the reciprocating screw 42, the movable slider 44 is slidably arranged on the inner side of the guide shell 41 and is sleeved on the outer side of the reciprocating screw 42 and is transmission-connected to the reciprocating screw 42, and the extension plate 45 is fixedly arranged on the side of the movable slider 44 away from the guide shell 41.

[0044] Therefore, when the driving motor 43 drives the reciprocating screw 42 to rotate, the reciprocating screw 42 drives the moving slider 44 to slide back and forth inside the guide shell 41. When the moving slider 44 slides, it drives the cleaning mechanism 5 to slide synchronously through the extension plate 45, so that the cleaning mechanism 5 cleans the dust or snow on the surface of the photovoltaic panel 3 to prevent the photovoltaic panel 3 from being damaged due to pressure caused by snow accumulation.

[0045] like Figure 3 As shown in the present disclosure, the cleaning mechanism 5 includes a housing 51, an avoidance channel 52, a rotating shaft 53, a rotating disk 54, a cleaning belt 55, an outer sleeve 56 and a locking bolt 57, wherein the housing 51, the avoidance channel 52, the rotating shaft 53, the rotating disk 54, the outer sleeve 56 and the locking bolt 57 are each provided with two, the two housings 51 are both fixedly arranged on the top of the extension plate 45, the two avoidance channels 52 are respectively opened on the side of the two housings 51 away from each other, and the two rotating shafts 53 respectively penetrate the two housings The two rotating shafts 53 are rotatably connected to the accommodating shells 51 through bearings. The two turntables 54 are fixedly arranged at the ends of the two rotating shafts 53. The two ends of the cleaning belt 55 are fixedly connected to the two rotating shafts 53 and wound around the outside of any one of the rotating shafts 53. The two outer sleeves 56 are respectively sleeved on the outside of the two rotating shafts 53 and are respectively fixedly connected to the adjacent accommodating shells 51. The two locking bolts 57 pass through the two outer sleeves 56 and are respectively connected to the two threads.

[0046] Therefore, when the cleaning effect of the cleaning belt 55 currently in contact with the photovoltaic panel 3 decreases due to wear, the two locking bolts 57 are loosened in succession so that the two locking bolts 57 respectively release the lock of the two rotating shafts 53, and then the two turntables 54 are rotated. When the turntables 54 are rotated, the rotating shafts 53 are driven to rotate, and the rotating shafts 53 wound with the cleaning belt 55 output the cleaning belt 55 during rotation, and the other rotating shaft 53 rewinds the cleaning belt 55 during rotation. At this time, the cleaning belt 55 originally located under the extension plate 45 is moved away under the rewinding of the rotating shaft 53, and the unworn part moves to the bottom of the extension plate 45, and then the two locking bolts 57 are tightened.
