Description

Technical Field

[0001] The utility model relates to the field of photovoltaic panel installation, and in particular to a polyurethane photovoltaic panel. Background Art

[0002] Polyurethane sheets are widely used in industries such as construction, refrigerated transportation, and furniture manufacturing due to their excellent thermal insulation properties, chemical corrosion resistance, and light weight and high strength. The structural design of installing photovoltaic panels on polyurethane sheets aims to combine solar energy conversion technology with building materials to achieve energy self-sufficiency in buildings.

[0003] Currently, photovoltaic panels are mostly installed on polyurethane sheets by bolting. Due to the material limitations of polyurethane sheets, the bolt-tightening method is prone to causing photovoltaic panels to slip when encountering strong winds or vibrations. This will not only cause damage to the photovoltaic panels, but also pose a danger to people. Utility Model Content

[0012] Figure 2 Shown Figure 1 A partial enlarged view of

[0013] Figure 3 A schematic structural diagram of a set of fixed legs is shown. DETAILED DESCRIPTION

[0014] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0015] Example 1

[0016] like Figures 1 to 3 A polyurethane photovoltaic panel is shown, in which the plate 1 is made of polyurethane material, the upper side of the plate 1 is covered with a color steel plate 2, and the upper side of the plate 1 is provided with parallel convex ridges 3. The color steel plate 2 completely covers the plate 1 and the convex ridges 3 and can be regarded as an integrated structure. Evenly distributed card slots 7 are provided on both sides of the convex ridges 3, and fixed supports 4 are installed at the card slots 7.

[0017] The fixed support leg 4 is composed of a side panel 41, a vertical panel 42, a top panel 44, and a clamping screw 45. Two vertical panels 42 are provided on the lower side of the top panel 44. The vertical panels 42 are symmetrically arranged with the center line of the top panel 44 as the central axis. The lower end of the vertical panel 42 is the side panel 41. The vertical panel 42 and the side panel 41 are integrated. A clamping head 43 is provided on the inner side of the lower part of the side panel 41. The inner side surface of the side panel 41 can be tightly attached to the side surface of the convex rib 3. The clamping head 43 can be tightly clamped in the slot 7. Concentric screw holes are provided on the two vertical panels 42, and the clamping screw 45 is locked in the screw hole with the nut.

[0018] In this embodiment, the middle parts of both sides of the convex rib 3 are concave. When installing the fixed support leg 4, first slightly pry apart the two side panels 41 and press the fixed support leg 4 down on the convex rib 3 from the top, or insert and slide it from one end of the convex rib 3 to the card slot 7. After the card head 43 is aligned with the card slot 7, press the two side panels 41 at the same time to press the card head 43 into the card slot 7 to complete the card connection and fixation.

[0019] In order to prevent the clamping head 43 from popping out after being connected to the clamping slot 7, the clamping slot 7 is provided with an upwardly inclined groove, and the clamping head 43 is also an upwardly inclined structure, so that the clamping head 43 is not easy to slide out.

[0020] If the card slot 7 and the card head 43 are upwardly inclined structures, the card head 43 will still slide downward after installation. In order to solve this problem, every two card slots 7 on the convex rib 3 are grouped together, and a connecting plate 47 is provided between the two fixed legs 4 installed at a group of card slots 7. The two ends of the connecting plate 47 are connected to the two top plates 44. A pressure plate is provided on the lower side of the connecting plate 47. A threaded hole 48 is provided in the center of the connecting plate 47. A threaded compression screw 49 is provided in the threaded hole 48, and a pressure plate 50 is provided at the lower end of the compression screw 49.

[0021] When the clamping head 43 is inserted into the clamping slot 7, the tightening screw 49 is rotated to press the pressure plate 50 downward, driving the fixed support leg 4 to rise a certain distance to ensure that the clamping head 43 does not slide downward from the clamping slot 7. The pressure plate 50 is prone to side slipping when pressed on the color steel plate 2, so the color steel plate 2 on the convex rib 3 is concave downward to form a shallow groove, and the pressure plate 50 is stuck in the shallow groove and will not slip.

[0022] The mounting frame 5 is mounted on the mounting screw holes 46 on the top plate 44 of the two fixed legs 4 through fixing bolts 6. The photovoltaic panel is fixedly mounted on the mounting frame 5. Therefore, in order to avoid protrusion when the clamping screw 49 is rotated, the threaded hole 48 is set as an embedded hole, and the nut at the upper end of the clamping screw 49 in the later stage of rotation is not higher than the upper side of the connecting plate 47.

[0023] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
