Description

Technical Field

[0001] The utility model relates to the field of photovoltaic power station equipment, in particular to a mobile pedal for repairing photovoltaic panels. Background Art

[0002] Building-integrated photovoltaic (BIPV) technology integrates solar power generation (PV) products into buildings. BIPV differs from PV systems that are simply attached to a building. BIPV can be divided into two main categories: one is the integration of PV arrays into buildings, and the other is the integration of PV arrays into buildings. Examples include photovoltaic tile roofs, photovoltaic curtain walls, and photovoltaic skylights. Of these two approaches, integrating PV arrays into buildings is a common method, particularly with building roofs. PV roofs are typically equipped with access walkways for routine maintenance.

[0003] However, during the construction, operation and maintenance of photovoltaic power station components, due to limited site and installation conditions, construction workers often step on photovoltaic components.

[0004] The utility model patent with Chinese patent number C219622121U discloses a photovoltaic operation and maintenance walkway system. The utility model includes a cross-arm guide rail and a connecting piece. The bottom of the cross-arm guide rail is fixed with a clamp by bolts. Two pressure blocks are fixed with bolts on the upper surface of the cross-arm guide rail. A walkway plate is fixed with bolts between the two pressure blocks. The concave connecting groove is fixedly connected to the pressure block by bolts. The walkway plate A is provided with a convex connecting groove on the right side, and the walkway plate B is provided with a convex inward folding connecting groove on the left and right sides. The convex connecting groove and the convex inward folding connecting groove are fixedly connected by bolts. The utility model proposes a photovoltaic operation and maintenance walkway system. This structure is fixed to the roof with a clamp, the cross-arm guide rail is fixed to the clamp, and the walkway plate is fixed to the cross-arm with a pressure block. The cross-arm mainly supports the walkway plate and strengthens the strength of the walkway plate, so that the operation and maintenance personnel can work safely and without obstacles on the roof. However, in actual use, this new type of equipment requires laying a large number of walkway boards each time, which is very cumbersome to operate. In addition, the walkway boards take up a large space, and when repairing rooftop photovoltaic panels, laying them is difficult and costly. Utility Model Content

[0005] The utility model aims at the shortcomings of the prior art and provides a photovoltaic panel maintenance movable pedal which has a simple structure and is easy to lay.

[0006] In order to solve the above technical problems, the present invention is solved by the following technical solutions:

[0007] The photovoltaic panel maintenance mobile pedal includes a pedal, a base and a connecting column. The connecting column is connected to the pedal and the base from top to bottom in sequence. The length direction of the pedal is perpendicular to the length direction of the base. The connecting column includes a column cap, a column and a limit ring. The limit ring is eccentrically arranged with the column and fixedly connected to the column. The base includes a top plate, a bottom plate and a connecting plate. The two ends of the connecting plate are respectively connected to the top plate and the bottom plate and are connected in an "I" shape. Grooves are symmetrically formed on the left and right sides of the connecting plate. The limit ring is located in the groove. Guide holes that cooperate with the column are symmetrically opened on the top plate. The guide holes are opened along the length direction of the base. The guide holes pass through the top plate and are connected to the groove. The radius of the limit ring is greater than the closest distance between the axis of the column and the connecting plate. When the limit ring does not conflict with the connecting plate, the connecting column can drive the pedal to move along the length direction of the guide hole. The overall structure is simple, and the cleverly designed connecting column can build the pedal on the base. The connecting column can move along the length of the guide hole, thereby driving the pedal to move to the desired position. The limit ring and the column are eccentrically arranged. When the limit ring contacts the side wall of the connecting plate, the pedal can be limited and fixed, and the operation is very simple.

[0008] Preferably, the connecting column further includes a roller, which is positioned within the groove. The column and the roller are coaxially arranged. The left and right sidewalls of the connecting plate each include a retaining groove that engages with the roller. The retaining groove extends along the length of the base, and the roller is embedded within the retaining groove and rotatably connected thereto. The provision of the roller not only strengthens the connection between the connecting column and the base but also allows for smoother movement of the connecting column along the length of the guide hole, thereby increasing the stability of the overall structure.

[0009] Preferably, the roller is located above the limiting ring, making the overall structure more compact.

[0010] Preferably, the limiting ring is fixedly connected to the lower end of the column, and a rubber ring is sleeved on the outer wall of the limiting ring. The setting of the rubber ring makes the interference between the limiting ring and the connecting plate more firm and not easy to loosen.

[0011] Preferably, the column cap is in the shape of an external hexagon or an internal hexagon, so as to facilitate the use of tools to rotate the connecting column.

[0012] Preferably, threaded holes are symmetrically provided at both ends of the pedal, and the column passes through the threaded holes and is threadedly connected to the pedal through the threaded holes, so as to make the connection between the pedal and the connecting column tighter.

[0013] Preferably, the upper surface of the pedal is provided with an anti-skid pad to increase the friction of the pedal and facilitate walking of the staff.

[0014] Preferably, the pedal is made of plastic, which is low in cost and light in weight, is easy to move, and is not prone to scratching the photovoltaic panels.

[0015] The utility model is designed with a movable pedal for inspecting photovoltaic panels. The overall structural design is ingenious. The ingeniously designed connecting column can build the pedal on the base. The connecting column can move along the length direction of the guide hole, thereby driving the pedal to move to the desired position. The limit ring and the column are eccentrically arranged. When the limit ring contacts the side wall of the connecting plate, the pedal can be limited and fixed, and the operation is very simple. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The present invention is described in further detail below with reference to the accompanying drawings and embodiments.

[0022] Example 1

[0023] Photovoltaic panel maintenance mobile pedal, such as Figure 1-4As shown, it includes a pedal 1, a base 2 and a connecting column 3. The connecting column 3 is connected to the pedal 1 and the base 2 in sequence from top to bottom. The length direction of the pedal 1 is perpendicular to the length direction of the base 2. The connecting column 3 includes a column cap 31, a column 32 and a limiting ring 33. The limiting ring 33 is eccentrically arranged with the column 32 and fixedly connected to the column 32. The base 2 includes a top plate 21, a bottom plate 22 and a connecting plate 23. The two ends of the connecting plate 23 are respectively connected to the top plate 21 and the bottom plate 22 and are connected in an "I" shape. The connecting plate Grooves 231 are symmetrically formed on the left and right sides of the base 23, and the limiting ring 33 is located in the groove 231. Guide holes 211 that cooperate with the column 32 are symmetrically opened on the top plate 21. The guide holes 211 are opened along the length direction of the base 2, pass through the top plate 21 and communicate with the groove 231. The radius of the limiting ring 33 is greater than the closest distance between the axis of the column 32 and the connecting plate 23. When the limiting ring 33 does not interfere with the connecting plate 23, the connecting column 3 can drive the pedal 1 to move along the length direction of the guide hole 211. The overall structure is simple, and the ingeniously designed connecting column 3 can be used to mount the pedal 1 on the base 2. The connecting column 3 can move along the length direction of the guide hole 211, thereby driving the pedal 1 to move to the desired position. The limiting ring 33 is eccentrically arranged with the column 32. When the limiting ring 33 interferes with the side wall of the connecting plate 23, the pedal 1 can be fixed in a limited position, which is very easy to operate.

[0024] The connecting post 3 also includes a roller 34, which is located within the groove 231. The post 32 and the roller 34 are coaxially arranged. The left and right sidewalls of the connecting plate 23 are each provided with a retaining groove 232 that engages with the roller 34. The retaining groove 232 extends along the length of the base 2. The roller 34 is inserted into the retaining groove 232 and is rotationally connected thereto. The provision of the roller 34 not only strengthens the connection between the connecting post 3 and the base 2 but also makes the movement of the connecting post 3 along the length of the guide hole 211 smoother and more stable, thereby increasing the stability of the overall structure.

[0025] The roller 34 is located above the limiting ring 33, making the overall structure more compact. The roller 34 can be connected to the column 32 through a bearing.

[0026] The limiting ring 33 is fixedly connected to the lower end of the column 32, and a rubber ring is sleeved on the outer wall of the limiting ring 33. The setting of the rubber ring makes the contact between the limiting ring 33 and the connecting plate 23 more firm and not easy to loosen.

[0027] The column cap 31 is in the shape of an outer hexagon or an inner hexagon, which is convenient for rotating the connecting column 3 using a tool.

[0028] Threaded holes 11 are symmetrically provided at both ends of the pedal 1, and the column 32 passes through the threaded holes 11 and is threadedly connected to the pedal 1 through the threaded holes 11, so that the connection between the pedal 1 and the connecting column 3 is tighter.

[0029] The upper surface of the pedal 1 is provided with an anti-skid pad 12. The friction of the pedal 1 is increased to facilitate the walking of the staff.

[0030] The working principle of the present utility model is to fix the base 2 on the photovoltaic panel bracket. When the pedal 1 needs to be moved, the limit ring 33 is rotated away from the connecting plate 23, the connecting column 3 is dragged, and the pedal 1 is moved to the desired maintenance position. The column cap 31 is rotated, and the column cap 31 drives the limit ring 33 to rotate through the column 32 and firmly contacts the side wall of the connecting plate 23. At this time, the position of the pedal 1 is fixed, and the maintenance personnel can step on the pedal 1 to perform maintenance work. In actual operation, when the limit ring 33 contacts the side wall of the connecting plate 23, the lower end face of the limit ring 33 contacts the upper end face of the bottom plate 22. In order to facilitate assembly, during actual assembly, the column cap 31 can be detachably connected to the column 32.

[0031] Example 2

[0032] The difference from embodiment 1 is that the column cap 31 is in the shape of a hexagonal socket, which makes it easier to rotate the connecting column 3 using a tool.

[0033] Example 3

[0034] The difference from Example 1 is that the pedal 1 is made of plastic. Plastic has the characteristics of low cost and light weight, is easy to move, and is not easy to scratch the photovoltaic panel.

[0035] The embodiment described above is only a preferred solution of the present invention and does not limit the present invention in any form. Other variations and modifications are possible without exceeding the technical solutions described in the claims.
