Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel module technology, specifically a drive mechanism for opening and closing a foldable photovoltaic module. Background Technology

[0002] Foldable photovoltaic modules are widely used in off-grid photovoltaic power generation systems and portable power supplies due to their convenient transportation and storage characteristics. However, the opening and closing of existing foldable photovoltaic modules is usually done manually. Since the photovoltaic panels are heavy, manual operation is time-consuming and labor-intensive, which greatly reduces the opening and closing efficiency. Furthermore, uneven stress on the photovoltaic panels can easily occur during operation, which can easily lead to damage to the foldable photovoltaic modules. Utility Model Content

[0003] The purpose of this invention is to provide a drive mechanism for opening and closing foldable photovoltaic modules, which can be applied in mobile container photovoltaic systems to facilitate the automatic opening and closing of foldable photovoltaic modules.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a driving mechanism for opening and closing a foldable photovoltaic module, comprising: a chain support, having two chain supports arranged in parallel; sprockets, with two sprockets rotatably mounted on each chain support, the sprockets on the two chain supports being arranged in a one-to-one correspondence; a chain assembly, with the two sprockets on each chain support cooperating to form a chain assembly; a transmission device for driving the chain assembly to move; and transmission components, which are mounted on a portion of the photovoltaic panel of the foldable photovoltaic module, with two transmission components mounted on this portion of the photovoltaic panel, the transmission components being used to cooperate with the two chain assemblies.

[0005] Furthermore, the transmission component includes: a connecting disc, which is fixedly connected to the photovoltaic panel of the foldable photovoltaic module; and a transmission gear, which is detachably mounted on the connecting disc. There are two transmission gears arranged in parallel, and the transmission gears are used to cooperate with the chain assembly.

[0006] Furthermore, the connecting plate is provided with a protrusion, which is used to fix and connect the photovoltaic panel of the foldable photovoltaic module.

[0007] Furthermore, the transmission gear plate is mounted on the connecting plate via a bolt and nut assembly.

[0008] Furthermore, the chain assembly includes two parallel drive chains, which are fitted to the outside of the sprocket, and the drive sprocket is adapted to the drive chains.

[0009] Furthermore, the transmission device includes: two drive shafts, which are positioned correspondingly and drive one of the sprockets on each chain support to rotate; and a motor, which is a dual-output motor, with its two output ends connected to the two drive shafts respectively.

[0010] Furthermore, it also includes support bars, with at least one support bar provided between the two chain supports.

[0011] Compared with the prior art, the beneficial effects achieved by this utility model are as follows.

[0012] 1. This utility model is applied to a mobile container photovoltaic system. Through the cooperation of the transmission component and the transmission chain, the photovoltaic panels of the foldable photovoltaic module can be automatically unfolded or refolded, thereby improving the opening and closing efficiency.

[0013] 2. Since the chain bracket, support bar, drive shaft, etc. are detachable, they can be placed on the container of the mobile containerized photovoltaic system or directly on the transport vehicle when not installed or used, which makes it convenient to disassemble and transport.

[0022] 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.

[0023] Example 1

[0024] Please see Figures 1-6 This utility model provides a technical solution: a driving mechanism for opening and closing a foldable photovoltaic module, comprising two parallel chain supports 1, each chain support 1 having two sprockets 5, the sprockets 5 being rotatably mounted on the chain support 1 via a rotating shaft (specifically, the sprockets 5 are fixedly connected to the rotating shaft, and the rotating shaft is mounted on the chain support 1 via a bearing); the two sprockets 5 on each chain support 1 cooperate to form a chain assembly 2, i.e., there are two chain assemblies 2; the driving mechanism also includes a transmission device 3 and a transmission component 6, the transmission device 3 being used to drive the two chain assemblies 2 to move; the transmission component 6 being mounted on a portion of the photovoltaic panel of the foldable photovoltaic module, and two transmission components 6 being mounted on the same photovoltaic panel, the transmission component 6 being used to cooperate with the two chain assemblies 2.

[0025] The chain assembly 2 includes a drive chain 21, which has a double-row chain structure and is fitted on the outside of the sprocket 5; and the drive chain 21 is used to cooperate with the transmission component 6.

[0026] The transmission component 6 includes a connecting plate 61, which is used to fix the foldable photovoltaic module's photovoltaic panel (hereinafter referred to as the photovoltaic panel). Two transmission gears 62 are provided on both sides of the connecting plate 61. The two transmission gears 62 are detachably mounted on the connecting plate 61 by bolt and nut assembly. The two transmission gears 62 are arranged in parallel. The transmission gears 62 are not complete circular gear structures, but have multiple teeth that are evenly distributed along an arc. The two transmission gears 62 are used to cooperate with the transmission chain 21 (the two transmission gears 62 respectively cooperate with the two rows of chains of the transmission chain 21).

[0027] The connecting plate 61 is provided with a protrusion 611, which is used to fix and connect the photovoltaic panel.

[0028] The transmission device 3 includes two transmission shafts 31, which drive one of the sprockets 5 on each chain bracket 1 to rotate. Specifically, since the sprocket 5 is rotatably mounted on the chain bracket 1 via a rotating shaft, the rotating shaft connected to one of the sprockets 5 on one of the chain brackets 1 is connected to one of the transmission shafts 31 via a coupling. The rotating shaft connected to one of the sprockets 5 on the remaining chain bracket 1 is also connected to the remaining transmission shaft 31 via a coupling. At the same time, the coupling is detachably connected to the rotating shaft and the transmission shaft 31, that is, the coupling is detachable, thereby making the transmission shaft 31 detachable.

[0029] The transmission device 3 also includes a motor (not shown in the figure). The motor is a dual-output shaft motor. The two output shafts of the motor are also fixedly connected to the two transmission shafts 31 through other couplings (the couplings here can be detachably connected to the transmission shafts 31 and the output shafts of the motor). The motor drives the two transmission shafts 31 to rotate synchronously, thereby driving the corresponding two sprockets 5 to rotate. With the cooperation of the transmission chain 21 and the remaining sprockets 5, the two transmission chains 21 can move synchronously.

[0030] In this embodiment, the entire drive mechanism is applied in a mobile containerized photovoltaic system or equipment. The foldable photovoltaic module is integrated into the container of the mobile containerized photovoltaic system. The chain bracket 1 can be detachably installed on the container by bolts or bolt-bolt assemblies, etc. Of course, the container adopts a box structure that can be opened and closed on each side. At the same time, the number of photovoltaic panels contained in the foldable photovoltaic module is an even number. Adjacent photovoltaic panels are hinged together by fasteners or other connecting parts, so that adjacent photovoltaic panels can be rotated and unfolded. Of course, when the photovoltaic panel is in contact with the fasteners or other connecting parts, the adjacent photovoltaic panels cannot be unfolded further. In addition, the foldable photovoltaic module is provided with pulleys, which cooperate with guide rails for laying and installing on the ground.

[0031] like Figure 6 As shown, the two photovoltaic panels on the far sides have one panel whose bottom end is used to rotate inside the container via a shaft or similar structure, while the bottom end of the other panel is fixedly connected to two transmission components 6. These two transmission components 6 are used to cooperate with two chain assemblies 2. Furthermore, the transmission components 6 and pulleys are spaced apart by one photovoltaic panel; half of the photovoltaic panels have transmission components 6 and pulleys, while the remaining half (including those rotatably mounted inside the container) do not have transmission components 6 or pulleys. Figure 6As shown, from left to right, the 1st, 3rd, 5th, 7th, 9th... photovoltaic panels do not have transmission components 6 and pulleys, while the 2nd, 4th, 6th, 8th, 10th... photovoltaic panels have transmission components 6 and pulleys. The first photovoltaic panel is used for rotation and is installed inside the container. The last photovoltaic panel has two transmission gears 62, which are used to cooperate with two transmission chains 21 after the drive mechanism is installed and fixed. Two pulleys can be installed on the same photovoltaic panel. By laying and installing two guide rails that are compatible with the pulleys on the ground, after the drive mechanism is installed and fixed, the two pulleys on the last photovoltaic panel are respectively engaged on the two guide rails.

[0032] When installing the fixed chain bracket 1, the two transmission gears 62 on the outermost photovoltaic panel (not the photovoltaic panel that is rotatably installed inside the container) are respectively engaged with the two transmission chains 21. Specifically, the teeth on the transmission gears 62 are engaged in a link on the transmission chain 21; the transmission chain 21 drives the outermost photovoltaic panel to move; at the same time, the two pulleys on the outermost photovoltaic panel are respectively engaged with the two guide rails.

[0033] Then, the motor drives the two drive shafts 31 to rotate, which in turn drives the two drive chains 21 to move, thereby moving the outermost photovoltaic panel. Before the drive toothed disc 62 on the photovoltaic panel disengages from the drive chain 21, the drive toothed disc 62 on the photovoltaic panel adjacent to the photovoltaic panel can engage with the drive chain 21. Specifically, this can be achieved by setting an appropriate number of chain links and setting the chain bracket 1 in a suitable position, which will not be elaborated here. After the pulley engages with the guide rail, the pulley will always engage with the guide rail (the guide rail is set to be very long) as the photovoltaic panel moves. When the drive toothed disc 62 on the photovoltaic panel adjacent to the photovoltaic panel that is rotatably mounted on the container engages with the drive chain 21, the drive toothed disc 62 is driven to move to a suitable position, and with the help of gravity and the engagement of the pulley and the guide rail, the photovoltaic panels can be unfolded.

[0034] Since two adjacent photovoltaic panels are hinged together by a connector, when the photovoltaic panel comes into contact with the connector, the two adjacent photovoltaic panels cannot continue to unfold. That is, the transmission gear 62 on the photovoltaic panel adjacent to the photovoltaic panel that is rotatably mounted on the container is engaged with the transmission chain 21, and the unfolding angle of the photovoltaic panel can be fixed by driving the transmission gear 62 to move to a suitable position.

[0035] Similarly, by rotating the motor in the opposite direction, the photovoltaic panels can be folded back up and stored inside the container.

[0036] Example 2

[0037] See again Figure 1 This embodiment, based on Embodiment 1, also includes a support strip 4, such as... Figure 1As shown, two support bars 4 are provided. After the chain bracket 1 is installed and fixed, the support bars 4 are used to connect the two chain brackets 1. The support bars 4 and the chain bracket 1 can be detachably connected, for example, the support bars 4 are connected to the chain bracket 1 by bolts or bolt and nut assemblies, which facilitates quick connection or disassembly. By setting the support bars 4, the stability of the chain bracket 1 can be improved.
