Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panels, in particular to a photovoltaic panel convenient for storage. Background Art

[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photovoltaic effect of the semiconductor cross-section. It mainly consists of three major parts: solar panels, controllers, and inverters. With the development of related technologies, photovoltaic power generation is applied to various environments.

[0003] For example, a Chinese patent document with the patent application number "CN201922277912.4" discloses an integrated solar tent. By fixing flexible solar sheets on the external hanging bag, the external hanging bag can be folded to store the flexible solar sheets. The solar sheets are fixed by fixing webbing nets, and the external hanging bag is fixed to the tent body through a connecting component to complete the installation. However, in this way, it is difficult to randomly adjust the use state of the solar sheets according to the actual environment during use, and the volume of the folded external hanging bag is greatly affected by the size of the solar sheets. That is to say, the minimum folding area is the limit of the surface area of a single photovoltaic panel, and the limitation is relatively large. Summary of the Utility Model

[0004] To solve the above technical problems, the utility model provides a photovoltaic panel convenient for storage, which can not only be conveniently stored, but also be unfolded or stored according to the actual use environment, facilitating use.

[0005] The utility model provides a photovoltaic panel convenient for storage to solve the above technical problems. It includes an outer cylinder body with a hollow interior. An installation component is provided on the outer cylinder body. Inside the outer cylinder body, a winding drum, a clockwork spring, a driving cylinder, and a limiting shaft fixed at both ends on the end part of the outer cylinder body are arranged in sequence from outside to inside. One end of the winding drum is rotatably connected to one end part of the outer cylinder body, and the other end is fixed to a rotary joint rotatably connected to the other end part of the outer cylinder body. A flexible photovoltaic component is wound around the outside of the winding drum. One end part of the flexible photovoltaic component is fixed to the winding drum, and the other end part extends outside the outer cylinder body through a strip-shaped notch on the outer cylinder body and is fixed to a limiting strip. The driving cylinder is rotatably sleeved on the limiting shaft and one end of it is fixed to the rotary joint. A self-locking mechanism is arranged between the driving cylinder and the limiting shaft. The clockwork spring is wound around the driving cylinder and one end of it is fixed to the rotary joint, and the other end is fixed to the end part of the outer cylinder body.

[0006] Further, the installation component includes a mounting plate fixed to the outer cylinder body. A strip-shaped groove is provided at the bottom of the mounting plate. A bidirectional screw is rotatably arranged in the strip-shaped groove. Threaded blocks slidably matched with the strip-shaped groove are respectively screwed at both ends of the bidirectional screw. Clamping plates are symmetrically arranged at the lower ends of the two threaded blocks.

[0007] Further, the self-locking mechanism includes a locking straight groove provided on the inner side wall of the driving cylinder. A positioning ball is rotatably provided in the locking straight groove. A winding ring groove, an unfolding ring groove, an unfolding arc groove and a winding arc groove provided between the winding ring groove and the unfolding ring groove are provided on the limiting shaft. A limiting groove for cooperating with the positioning ball is provided in the middle of the winding arc groove.

[0008] Further, the unfolding arc groove includes an unfolding inner arc surface and an unfolding outer arc surface. An unfolding protrusion protruding from the end of the unfolding inner arc surface is provided at one end of the unfolding outer arc surface close to the winding ring groove. The winding arc groove includes a winding outer arc surface and a winding inner arc surface. A winding protrusion protruding from the end of the winding inner arc surface is provided at one end of the winding outer arc surface close to the unfolding ring groove.

[0009] Further, the flexible photovoltaic module includes a flexible substrate and a flexible photovoltaic panel provided on the flexible substrate.

[0010] Further, the width of the limiting strip is greater than the width of the strip-shaped notch, and a pull ring is provided on the limiting strip.

[0011] The beneficial effects of adopting the utility model are as follows. The outer cylinder is used to accommodate the flexible photovoltaic module. The mounting gradually on the outer cylinder is used to fix the outer cylinder on the top of the tent or other articles. The reel inside the outer cylinder is used to support the flexible photovoltaic module. When the reel rotates, the flexible photovoltaic module can be unfolded to receive light, or wound on the reel for convenient storage, transportation, etc. The flexible photovoltaic module is wound outside the reel. One end of the flexible photovoltaic module is fixed to the reel, and the other end extends to the outside of the outer cylinder through the strip-shaped notch and is fixed to the limiting strip. When pulling the limiting strip to drive the flexible photovoltaic module to unfold from the reel, the reel is driven to rotate inside the outer cylinder, and the rotating joint is driven to rotate when the reel rotates. Also, since the clockwork spring is wound around the driving cylinder and one end is fixed to the rotating joint and the other end is fixed to the end of the outer cylinder, elastic potential energy is stored in the clockwork spring during the rotation of the rotating joint. When the limiting strip is released, since the clockwork spring releases the stored elastic potential energy, the rotating joint reverses, driving the reel to rotate reversely to wind the flexible photovoltaic module on the reel. At the same time, since the driving cylinder is rotatably sleeved on the limiting shaft and one section of it is fixed to the rotating joint, when the rotating joint rotates, the driving cylinder is driven to rotate. A self-locking mechanism is provided between the driving cylinder and the limiting shaft. After the limiting strip is released, while the clockwork spring drives the rotating joint to rotate reversely, the driving cylinder is also driven to rotate reversely. The self-locking mechanism is used to self-lock the rotation of the driving cylinder, and thus self-lock the rotation of the reel to achieve the effect of stopping at any time when pulled. Furthermore, it is convenient to store the flexible photovoltaic panel module without affecting its power generation efficiency, and the unfolded area of the flexible photovoltaic module can be controlled according to actual use requirements, which is convenient to use.

[0012] When the marathon limiting strip unfolds the flexible photovoltaic module from the reel, it drives the rotary joint to rotate, and then drives the driving cylinder to rotate on the limiting shaft. At this time, while the positioning ball rolls in the locking straight groove, it passes through the unfolding arc groove from the winding ring groove on the limiting shaft and rolls into the unfolding ring groove. Continuously pulling the limiting strip, the position of the ball in the locking straight groove is fixed and it rolls along the unfolding ring groove. At the same time, the clockwork spring stores elastic potential energy; after releasing the limiting strip, the clockwork spring releases elastic potential energy, driving the rotary joint to reverse. While the positioning ball rolls in the locking straight groove, it enters the winding arc groove from the unfolding ring groove until it moves to the limiting groove. The limiting groove limits the positioning ball, making the driving cylinder unable to continue rotating, thereby realizing the self-locking of the reel; when it is necessary to completely wind up the flexible photovoltaic module, appropriately pull the limiting strip to drive the reel to rotate forward, and then drive the driving cylinder to rotate forward. At this time, the positioning ball enters the winding ring groove from the limiting groove along the winding arc groove. After releasing the limiting strip, under the action of the elastic potential energy released by the clockwork spring, it drives the driving cylinder to reverse, and then drives the reel to reverse through the rotary joint to wind up the flexible photovoltaic module on the reel.

Detailed Embodiments

[0019] With reference to the accompanying drawings, specific embodiments of the present utility model will be described in detail.

[0020] With reference to Figures 1 to 4 , the present utility model provides an embodiment of a photovoltaic panel that is convenient for storage.

[0021] A photovoltaic panel that is convenient for storage includes an outer cylinder body 1 with a hollow interior. An installation component 2 is provided on the outer cylinder body 1. The outer cylinder body 1 is used to accommodate a flexible photovoltaic module 8, and the installation component on the outer cylinder body 1 is used to fix the outer cylinder body 1 on the top of a tent or other objects. A photovoltaic controller is also provided on the outer cylinder body 1, which is connected to a flexible photovoltaic panel 83 in the flexible photovoltaic module 8 through a wire. Specifically, the installation component 2 includes a mounting plate 21 fixed to the outer cylinder body 1. A strip groove 211 is provided at the bottom of the mounting plate 21. A bidirectional screw 22 is rotatably provided in the strip groove 211. Threaded blocks 23 that are slidably engaged with the strip groove 211 are respectively screwed to both ends of the bidirectional screw 22. Clamping plates 24 are symmetrically provided at the lower ends of the two threaded blocks 23. Further, one end of the bidirectional screw 22 passes through the strip groove 211 and is provided with a knob. Among them, the threaded block 23 is provided with a threaded hole that cooperates with the bidirectional screw 22. A guide block is provided on the side of the threaded block 23, and the guide block is slidably engaged with a chute on the side wall of the strip groove 211 to prevent the threaded block 23 from rotating, so that it can only make a reciprocating linear motion along the axial direction of the bidirectional screw 22. During installation, the two clamping plates 24 are clamped on the support rod at the top of the tent or the support rod of other objects, the bidirectional screw 22 is rotated, driving the two threaded blocks 23 to move towards each other on the bidirectional screw 22, and then the two clamping plates 24 are clamped on the support rod to fix the outer cylinder body 1.

[0022] A winding drum 3, a clockwork spring 4, a driving cylinder 5, and a limiting shaft 6 fixed to the ends of the outer cylinder body 1 are sequentially arranged inside the outer cylinder body 1 from outside to inside. The winding drum 3 inside the outer cylinder body 1 is used to support the flexible photovoltaic module 8. When the winding drum 3 rotates, the flexible photovoltaic module 8 can be unfolded to receive light, or wound on the winding drum 3 for convenient storage, transportation, etc.; the clockwork spring 4 provides elastic potential energy for the winding drum 3, and a self-locking mechanism provided by the cooperation of the driving cylinder 5 and the limiting shaft 6 is used to self-lock the rotation of the winding drum 3 to achieve the effect of stopping at any time when pulled.

[0023] One end of the drum 3 is rotatably connected to one end of the outer cylinder 1, and the other end is fixed to a rotary joint 7 rotatably connected to the other end of the outer cylinder 1. A flexible photovoltaic module 8 is wound around the outside of the drum 3. One end of the flexible photovoltaic module 8 is fixed to the drum 3, and the other end extends outside the outer cylinder 1 through a strip-shaped notch 11 on the outer cylinder 1 and is fixed to a limiting strip 81. Further, the width of the limiting strip 81 is greater than the width of the strip-shaped notch 11 to prevent the limiting strip 81 from retracting into the outer cylinder 1. A pull ring 811 is provided on the limiting strip 81 to facilitate pulling out the flexible photovoltaic module 8 through the limiting strip 81. And due to the arrangement of the pull ring 811, when the outer cylinder 1 is installed on the top of the tent, the flexible photovoltaic module 8 can be pulled out of the outer cylinder 1 by hooking a hook into the pull ring 811, which is convenient for use. Of course, a pull rope can also be provided on the limiting strip 81 to facilitate pulling the flexible photovoltaic module 8. When the limiting strip 81 is pulled, the flexible photovoltaic module 8 is driven to unwind from the drum 3, driving the drum 3 to rotate inside the outer cylinder 1. When the drum 3 rotates, it drives the rotary joint 7 to rotate. Among them, the flexible photovoltaic module 8 includes a flexible substrate 82 and flexible photovoltaic panels 83 provided on the flexible substrate 82. The substrate is used to connect the flexible photovoltaic panels 83 to the drum 3.

[0024] The drive cylinder 5 is rotatably sleeved on the limiting shaft 6 and one end thereof is fixed to the rotary joint 7. When the rotary joint 7 rotates, it drives the drive cylinder 5 to rotate on the limiting shaft 6. The clockwork spring 4 is wound around the drive cylinder 5 and one end thereof is fixed to the rotary joint 7, and the other end is fixed to the end of the outer cylinder 1. During the forward rotation of the rotary joint 7, the clockwork spring 4 stores elastic potential energy; when the limiting strip 81 is released, due to the clockwork spring 4 releasing the stored elastic potential energy, the rotary joint 7 reverses, driving the drum 3 to rotate reversely to wind the flexible photovoltaic module 8 on the drum 3.

[0025] In some embodiments, a self-locking mechanism is provided between the driving cylinder 5 and the limiting shaft 6. The self-locking mechanism includes a locking straight groove 51 provided on the inner side wall of the driving cylinder 5. A positioning ball 52 is rotatably provided in the locking straight groove 51. A winding ring groove 61, an unfolding ring groove 62, an unfolding arc groove 63 and a winding arc groove 64 are provided on the limiting shaft 6 and are in rolling cooperation with the positioning ball 52. A limiting groove 65 for cooperating with the positioning ball 52 is provided in the middle of the winding arc groove 64. Among them, the unfolding plane of the winding arc groove 64 is in a V-shaped structure, and the limiting groove 65 is provided at the closed end of the V-shaped structure. The unfolding plane of the unfolding arc groove 63 is in a quarter-circular shape. At this time, when the limiting strip 81 is pulled to unwind the flexible photovoltaic module 8 from the reel 3, the rotary joint 7 is driven to rotate, and then the driving cylinder 5 is driven to rotate on the limiting shaft 6. While the positioning ball 52 rolls in the locking straight groove 51, it rolls from the winding ring groove 61 on the limiting shaft 6 through the unfolding arc groove 63 into the unfolding ring groove 62. By continuously pulling the limiting strip 81, the position of the ball in the locking straight groove 51 is fixed and it rolls along the unfolding ring groove 62. At the same time, the clockwork spring 4 stores elastic potential energy. After the limiting strip 81 is released, the clockwork spring 4 releases the elastic potential energy, driving the rotary joint 7 to reverse. While the positioning ball 52 rolls in the locking straight groove 51, it enters the winding arc groove 64 from the unfolding ring groove 62 until it moves to the limiting groove 65. The limiting groove 65 limits the positioning ball 52, preventing the driving cylinder 5 from continuing to rotate, thereby realizing the self-locking of the reel 3. When it is necessary to completely wind up the flexible photovoltaic module 8, the limiting strip 81 is appropriately pulled to drive the reel 3 to rotate forward, and then drive the driving cylinder 5 to rotate forward. At this time, the positioning ball 52 enters the winding ring groove 61 from the limiting groove 65 along the winding arc groove 64. After the limiting strip 81 is released, under the action of the elastic potential energy released by the clockwork spring 4, the driving cylinder 5 is driven to reverse, and then the reel 3 is driven to reverse through the rotary joint 7 to wind up the flexible photovoltaic module 8 on the reel 3.

[0026] Furthermore, the unfolding arc groove 63 includes an unfolding inner arc surface 631 and an unfolding outer arc surface 632. One end of the unfolding outer arc surface 632 close to the winding ring groove 61 is provided with an unfolding protrusion 633 protruding from the end of the unfolding inner arc surface 631; the winding arc groove 64 includes a winding outer arc surface 641 and a winding inner arc surface 642. One end of the winding outer arc surface 641 close to the unfolding ring groove 62 is provided with a winding protrusion 643 protruding from the end of the winding inner arc surface 642. Preferably, both the unfolding protrusion 633 and the winding protrusion 643 can be set as flexible structures to guide the movement track of the positioning ball 52. When pulling the limiting strip 81 to drive the reel 3 to rotate forward, the positioning ball 52 rolls along the winding ring groove 61 and enters the unfolding arc groove 63 under the guiding action of the unfolding protrusion 633. When the limiting strip 81 is released, the positioning ball 52 rolls reversely in the unfolding ring groove 62 and enters the winding arc groove 64 under the guiding action of the winding protrusion 643.
