A multi-layer foldable photovoltaic panel

Abstract

This utility model belongs to the field of photovoltaic panels, specifically relating to a multi-layer foldable photovoltaic panel, including a main body of the device. The main body is characterized by a photovoltaic device on its surface, comprising an unfolding electric rod. This multi-layer foldable photovoltaic panel, by incorporating the photovoltaic device, allows the photovoltaic panel to be retracted when the telescopic device is activated, causing the photovoltaic panels to stack. During retraction, the surface of the pressure plate of the upper photovoltaic panel presses against the moving rod of the lower photovoltaic panel, causing the moving rod to move and compress a spring. The moving column is slidably connected within a sliding groove. When the moving rod is about to retract into the mounting frame, the moving column moves into position, and the positioning head engages with the fixing hole, thus being pushed by the moving rod. The swinging of the hinge rod pushes out a rubber strip to seal the lower photovoltaic panel, thereby protecting the photovoltaic panel when not in use.

Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel technology, specifically a multi-layer foldable photovoltaic panel. Background Technology

[0002] A photovoltaic (PV) panel is a device that converts solar energy into electrical energy. It is widely used in various power generation systems. The core component of a PV panel is a photovoltaic cell made of semiconductor materials. When sunlight shines on a PV panel, photons are absorbed by the semiconductor material, and electrons are excited from atoms, forming electron-hole pairs. These electrons and holes move directionally under the influence of an electric field, thereby generating an electric current. The PV panel converts solar energy into electrical energy, and an inverter converts direct current (DC) into alternating current (AC) for user consumption. Throughout the entire process, there are no moving mechanical parts, and no pollutants or greenhouse gases are produced.

[0003] Currently, in most existing technologies, after folding, most multi-layer foldable photovoltaic panels still have gaps between the photovoltaic panels. When not in use, moisture and dust from the outside air can easily enter the interior of the foldable photovoltaic panels through these gaps. Therefore, we propose a... Utility Model Content

[0006] An electric pole is deployed, with one end of the electric pole located on the upper surface of the main body of the device, and the other end of the electric pole hinged to the surface of the telescopic device. A mounting frame is fixedly connected to the surface of the telescopic device, and a photovoltaic panel is fixedly connected to the inner wall of the mounting frame.

[0007] Preferably, a movable rod is slidably connected to the inner wall of the mounting frame, and a sliding groove is formed on the inner wall of the movable rod, and a fixing hole is formed on the inner wall of the sliding groove.

[0008] Preferably, a movable column is slidably connected to the inner wall of the sliding groove, and the inner walls on both sides of the movable column are connected to the positioning head by springs. The surface of the movable column is hinged to one end of the hinge rod, and the other end of the hinge rod is hinged to the upper surface of the ejector plate. A rubber strip is fixedly connected to the bottom surface of the ejector plate.

[0009] Preferably, the inner wall of the mounting frame is fixedly connected to one end of the spring, the other end of the spring is fixedly connected to the surface of the moving rod, and a pressure plate is fixedly connected to the surface of the mounting frame.

[0010] Preferably, the main body of the device includes a base plate, a control device is fixedly connected to the upper surface of the base plate, and a set of casters is fixedly connected to the bottom surface of the base plate.

[0011] Preferably, the upper surface of the base plate is hinged to the end face of the deployable electric rod.

[0012] Beneficial effects

[0013] This invention provides a multi-layer foldable photovoltaic panel. It has the following beneficial effects:

[0014] (1) The multi-layer foldable photovoltaic panel, by setting up a photovoltaic device, when the photovoltaic panel needs to be retracted, when the telescopic device is activated, the telescopic device retracts the photovoltaic panel, so that the photovoltaic panel is stacked. When the photovoltaic panel above is retracted, the surface of its pressure plate presses the moving rod of the photovoltaic panel below, so that the moving rod moves to compress the spring. The moving column slides in the sliding groove. When the moving rod is about to be retracted into the installation frame, the moving column moves into place, the positioning head is locked into the fixing hole, and is thus pushed by the moving rod. The swing of the hinge rod pushes out the rubber strip to seal the photovoltaic panel below, thus protecting the photovoltaic panel when it is not needed.

[0015] (2) The multi-layer foldable photovoltaic panel, through the positioning head, when the photovoltaic panel needs to be unfolded, when the telescopic device is activated, the telescopic device pushes out the photovoltaic panel. When the photovoltaic panel above is unfolded, the surface of its pressure plate no longer presses the moving rod of the photovoltaic panel below. Its spring returns to its original position, thereby pushing out the moving rod. When the moving rod is pushed out, the moving column pulls the push-out plate and the rubber strip to return to their original positions. After the push-out plate returns to its original position, the moving rod continues to move, thereby causing the fixing hole to press the positioning head, forcing the positioning head to disengage from the fixing hole, so that the moving column slides in the sliding groove until the moving rod is completely returned to its original position. At the beginning, the rubber strip can be quickly pulled open, thereby avoiding frequent friction between the rubber strip and the mounting frame, thus ensuring the durability of the rubber strip.

[0024] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-6 This utility model proposes a multi-layer foldable photovoltaic panel, including a device body 1. The device body 1 includes a base plate 101. A control device 102 is fixedly connected to the upper surface of the base plate 101. A moving wheel 103 is fixedly connected to the bottom surface of the base plate 101. The upper surface of the base plate 101 is hinged to the end face of the unfolding electric rod 201.

[0027] A photovoltaic device 2 is installed on the surface of the main body 1. The photovoltaic device 2 includes: an extendable electric rod 201, one end of which is located on the upper surface of the main body 1, and the other end of which is hinged to the surface of a telescopic device 202. A mounting frame 203 is fixedly connected to the surface of the telescopic device 202. A photovoltaic panel 204 is fixedly connected to the inner wall of the mounting frame 203. A movable rod 205 is slidably connected to the inner wall of the mounting frame 203. A sliding groove 206 is formed on the inner wall of the movable rod 205. A fixing hole 207 is formed on the inner wall of the sliding groove 206. A movable column 208 is slidably connected to the inner wall of the sliding groove 206. The inner walls of both sides of the movable column 208 are connected to a positioning head 209 by springs. When the photovoltaic panel 204 needs to be unfolded, the telescopic device 202 is activated, causing the positioning head 209 to extend the photovoltaic panel 204. As the photovoltaic panel 204 unfolds, the surface of the pressure plate 214 no longer presses against the moving rod 205 of the lower photovoltaic panel 204. The spring 211 resets, thus extending the moving rod 205. When the moving rod 205 is extended, the moving column 208 pulls the ejection plate 212 and rubber strip 213 to reset. After the ejection plate 212 resets, the moving rod 205 continues to move, causing the fixing hole 207 to press against the positioning head 209, forcing the positioning head 209 out of the fixing hole 207. This allows the moving column 208 to slide within the sliding groove 206. Once the movable rod 205 is fully reset, the rubber strip 213 can be quickly pulled apart at the beginning, thus avoiding frequent friction between the rubber strip 213 and the mounting frame 203, thereby ensuring the durability of the rubber strip 213. The surface of the movable column 208 is hinged to one end of the hinge rod 210, and the other end of the hinge rod 210 is hinged to the upper surface of the push-out plate 212. The bottom surface of the push-out plate 212 is fixedly connected to the rubber strip 213. The inner wall of the mounting frame 203 is fixedly connected to one end of the spring 211, and the other end of the spring 211 is fixedly connected to the surface of the movable rod 205. The surface of the mounting frame 203 is fixedly connected to the pressure plate 214. By setting up the photovoltaic device 2, when the photovoltaic panel 204 needs to be retracted, the telescopic device 20 is activated. At time 2, the telescopic device 202 retracts the photovoltaic panel 204, causing the photovoltaic panels 204 to be stacked. When the upper photovoltaic panel 204 is retracted, the surface of its pressure plate 214 presses against the moving rod 205 of the lower photovoltaic panel 204, causing the moving rod 205 to move and compress the spring 211. The moving column 208 is slidably connected inside the sliding groove 206. When the moving rod 205 is about to be retracted into the mounting frame 203, the moving column 208 moves into place, and the positioning head 209 is inserted into the fixing hole 207, thereby being pushed by the moving rod 205. The swing of the hinge rod 210 pushes out the rubber strip 213 to seal the lower photovoltaic panel 204, thus protecting the photovoltaic panel 204 when it is not in use.

[0028] In this invention, when the photovoltaic panel 204 needs to be retracted during use, the telescopic device 202 is activated, causing the photovoltaic panels 204 to be stacked. During retraction, the surface of the pressure plate 214 of the upper photovoltaic panel 204 presses against the moving rod 205 of the lower photovoltaic panel 204, causing the moving rod 205 to move and compress the spring 211. The moving column 208 is slidably connected inside the sliding groove 206. When the moving rod 205 is about to be retracted into the mounting frame 203, the moving column 208 moves into position, and the positioning head 209 engages with the fixing hole 207, thus being pushed by the moving rod 205. The swinging of the hinge rod 210 pushes out the rubber strip 213 to press against the lower photovoltaic panel 204. When the photovoltaic panel 204 needs to be unfolded, the telescopic device 202 is activated, and the telescopic device 202 pushes out the photovoltaic panel 204. When the photovoltaic panel 204 above unfolds, the surface of the pressure plate 214 no longer presses against the moving rod 205 of the photovoltaic panel 204 below. The spring 211 resets, thus pushing out the moving rod 205. When the moving rod 205 is pushed out, the moving column 208 pulls the push-out plate 212 and the rubber strip 213 to reset. After the push-out plate 212 is reset, the moving rod 205 continues to move, so that the fixing hole 207 presses against the positioning head 209, forcing the positioning head 209 to disengage from the fixing hole 207, so that the moving column 208 slides in the sliding groove 206 until the moving rod 205 is completely reset.

All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
