Detailed Description
The invention discloses a photovoltaic module system with a self-protection function, which can avoid dust or snow deposited on the surface of a battery plate, so that the battery plate is ensured to generate electricity normally, and a photovoltaic power station is ensured to supply power stably.
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to fall within the scope of the invention.
In the description of the present invention, the terms "upper", "lower", "top", "bottom", and the like refer to the orientation or positional relationship based on that shown in the drawings, for convenience of description of the present invention only and are not required to necessarily construct and operate in a particular orientation, and thus should not be construed as limiting the present invention.
The invention discloses a photovoltaic module system with a self-protection function, which comprises: the driving assembly, the base 1-2 and the battery plate 1-1. Wherein the bottom of the battery plate 1-1 is hinged at the edge part of the base 1-2, and the top of the battery plate 1-1 is hinged with the driving component. The function of the drive assembly is to drive the panel 1-1 inwardly around the bottom of the panel 1-1 or towards the centre of the base 1-2, and also to drive the panel 1-1 outwardly around the bottom of the panel 1-1 or away from the base 1-2. The number of the battery plates 1-1 is plural, and the plurality of battery plates 1-1 are arranged around the base 1-2. The plurality of battery panels 1-1 are driven by a drive assembly.
When the driving assembly drives the plurality of battery plates 1-1 to turn inwards, the folding process of the battery plates 1-1 is the process. When the driving assembly drives the plurality of battery plates 1-1 to turn outwards, the opening process of the battery plates 1-1 is the process. The folding and unfolding of the panel 1-1 is similar to the folding and unfolding of flowers.
When the solar panel 1-1 is folded through the driving assembly in sandy dust, rain and snow weather, so that the solar panel 1-1 is prevented from being contacted with dust or rain and snow, dust or rain and snow is prevented from being deposited on the solar panel 1-1, normal power generation of the solar panel 1-1 is ensured, and stable power supply of a photovoltaic power station is ensured. In addition, the dust deposition is avoided, so that the hot spot effect is avoided, and the manual maintenance cost and the material cost are reduced.
When weather is good, the panel 1-1 is controlled to be opened by the driving assembly so that the panel 1-1 sufficiently receives sunlight.
It should be noted that the working surface of the battery plate 1-1 faces the center of the base 1-2, and the non-working surface of the battery plate 1-1 faces away from the base 1-2. When the panel 1-1 is folded, the working surface of the panel 1-1 is positioned at the inner side of the folding structure, so that dust or rain and snow can be prevented from being deposited on the working surface of the panel 1-1.
The invention arranges the base 1-2 into a disc shape, and a plurality of battery plates 1-1 are arranged around. The panel 1-1 forms a bowl shape with the base 1-2 when the panel 1-1 is in an open state.
Because the cell plates 1-1 are arranged around, 360 degrees of all-round sunlight is received, and therefore the power generation efficiency is improved.
The invention designs the shape of the battery plate 1-1 into a rectangle, and the wide side of the battery plate 1-1 with the rectangle structure is hinged on the base 1-2. Thus, the cell plates 1-1 are arranged in a ring shape, and the circumferential curve of 360 degrees is more met, so that a 360-degree omnibearing lighting mode is better formed.
In the adjacent two panels 1-1, the edge portion of the former panel 1-1 is superposed on the edge portion of the latter panel 1-1 along one circumferential direction of the base 1-2. The edge portion of each of the preceding panels 1-1 is superposed on the edge portion of the following panel 1-1. This arrangement ensures that there is no gap between two adjacent panels 1-1. When the panels 1-1 are in the folded state, since no gap exists between two adjacent panels 1-1, dust or rain and snow can be prevented from entering the inner side of the folded structure through the gap, and dust or rain and snow are further prevented from being deposited on the working surface of the panels 1-1.
It should be noted that, since two adjacent panels 1-1 are stacked, when the driving assembly drives the panels 1-1 to turn over, there is a pulling effect between the adjacent panels 1-1, and in two adjacent cells, one panel 1-1 can pull the other panel 1-1 to turn over. Thus, the overturning synchronism of the battery plate 1-1 is ensured, and the folding or unfolding stability of the battery plate 1-1 is improved.
In the invention, the peripheral edge part of the battery plate 1-1 is wrapped with an aluminum alloy frame. The aluminum alloy frame has a protective effect on the battery plate 1-1. The hinged parts of the battery plate 1-1 and the driving component as well as the base 1-2 are arranged on the aluminum alloy frame.
The drive assembly is specifically described as follows: the drive assembly comprises an electric telescopic shaft 2-1 and connecting shafts 2-2, 1-3. The bottom of the electric telescopic shaft 2-1 is fixedly connected in the base 1-2, one end of the connecting shafts 2-2 and 1-3 is hinged to the top of the electric telescopic shaft 2-1, and the other end is hinged to the top of the battery plate 1-1. The number of the connecting shafts 2-2, 1-3 is equal to the number of the battery plates 1-1. Each connecting shaft 2-2, 1-3 corresponds to one panel 1-1. When the electric telescopic shaft 2-1 extends upwards, one end of the connecting shafts 2-2 and 1-3 connected with the electric telescopic shaft 2-1 can be lifted, so that the corresponding battery plate 1-1 can be driven to be folded. When the electric telescopic shaft 2-1 is contracted, one end of the connecting shafts 2-2 and 1-3 connected with the electric telescopic shaft 2-1 is lowered, so that the corresponding battery plate 1-1 is pushed to turn outwards, and the expansion of the battery plate 1-1 is realized.
The electric telescopic shaft 2-1 specifically includes a plurality of telescopic shafts and a driving portion, please refer to fig. 2. Except the topmost telescopic shaft and the bottommost telescopic shaft, the inner cavity of each telescopic shaft comprises an upper limiting plate 2-1-2 and a lower limiting plate 2-1-3, and the bottom of each telescopic shaft is connected with a clamping plate 2-1-4. In the two adjacent telescopic shafts, the clamping plate 2-1-4 of the upper telescopic shaft is hidden in the inner cavity of the lower telescopic shaft, and the clamping plate 2-1-4 of the upper telescopic shaft 2-1-1 is blocked by the upper limiting plate 2-1-2 and the lower limiting plate 2-1-3 of the lower telescopic shaft. The upper telescopic shaft can be retracted into the inner cavity of the lower telescopic shaft, and can extend out of the inner cavity of the lower telescopic shaft. For the telescopic shaft at the top end, only the clamping plates 2-1-4 connected with the telescopic shaft are needed. For the telescopic shaft at the bottommost end, only the upper limiting plate 2-1-2 and the lower limiting plate 2-1-3 are required to be arranged. The driving part is used for driving the topmost telescopic shaft to ascend or descend.
In the process that the driving part drives the topmost telescopic shaft to ascend, the topmost telescopic shaft stretches out from the inner cavity of the secondary top telescopic shaft, after the clamping plate 2-1-4 of the topmost telescopic shaft touches the upper limiting plate 2-1-2 of the secondary top telescopic shaft, the clamping plate 2-1-4 forms upward thrust to the upper limiting plate 2-1-2, and the topmost telescopic shaft can drive the secondary top telescopic shaft to stretch out from the inner cavity of the secondary top telescopic shaft, so that the telescopic shafts stretch out sequentially.
In the process that the driving part drives the topmost telescopic shaft to descend, the topmost telescopic shaft is retracted into the inner cavity of the telescopic shaft at the secondary top, after the clamping plate 2-1-4 of the topmost telescopic shaft contacts the lower limiting plate 2-1-3 of the telescopic shaft at the secondary top, the clamping plate 2-1-4 can form downward thrust to the lower limiting plate 2-1-3, and the topmost telescopic shaft can push the telescopic shaft at the secondary top to retract into the inner cavity of the telescopic shaft at the secondary top, so that the telescopic shafts are sequentially retracted.
The driving part specifically comprises a driving motor 2-1-7, a rope 2-1-6 and a spring 2-1-5. The driving motor 2-1-7 is arranged on the base 1-2 and is positioned in the inner cavity of the telescopic shaft at the bottommost end. The ropes 2-1-6 penetrate through all the telescopic shafts, one ends of the ropes 2-1-6 are connected with a motor shaft of the driving motor 2-1-7, and the other ends of the ropes are connected with the telescopic shafts at the top ends. The springs 2-1-5 are arranged in a similar manner to the ropes 2-1-6, with the springs 2-1-5 extending through all of the telescopic shafts. One end of the spring 2-1-5 is fixedly connected to the base 1-2, and the other end is connected with the topmost telescopic shaft. The natural length of the springs 2-1-5 is greater than the overall length of the motorized telescopic shaft 2-1, so that the springs 2-1-5 are always in a compressed state.
The springs 2-1-5 provide an upward pushing force to the topmost telescopic shaft and the ropes 2-1-6 provide a pulling force to the topmost telescopic shaft. If the ropes 2-1-6 are not provided, the telescopic shaft is always in an extended state under the elastic force of the springs 2-1-5. The ropes 2-1-6 are wound around the motor shafts of the driving motors 2-1-7. If the driving motor 2-1-7 rotates forward, the rope 2-1-6 is gradually scattered down from the motor shaft, and the electric telescopic shaft 2-1 is gradually stretched under the action of the pushing force of the spring 2-1-5 in the process that the rope 2-1-6 is gradually lengthened. If the driving motor 2-1-7 is reversed, the ropes 2-1-6 are wound on the motor shaft gradually, and the electric telescopic shaft 2-1 is contracted gradually under the action of the tensile force of the ropes 2-1-6 in the process that the ropes 2-1-6 are shortened gradually. In the present invention, the opening or closing angle of the panel 1-1 can be controlled by controlling the length of the ropes 2-1-6.
It should be noted that, the electric telescopic shaft 2-1 in the present invention is a multi-stage telescopic shaft, that is, the extent of contraction and extension of the electric telescopic shaft 2-1 can be sufficiently large, so that the battery plate 1-1 can be ensured to be fully unfolded and simultaneously fully folded.
In order to make the panel 1-1 better able to receive sunlight, the invention also provides a support assembly to give the panel 1-1 a certain height. The support assembly specifically comprises a base 4 and a support bar 3. The bottom of the supporting rod 3 is fixedly connected to the base 4, and the base 1-2 is fixedly connected to the top of the supporting rod 3. The foundation 4 may be a reinforced concrete pile. The support rod 3 is preferably made of aluminum alloy. The aluminum alloy has the advantages of high strength, corrosion resistance and the like.
The power supply principle of the battery panel 1-1 is described as follows: the current of each cell plate 1-1 is converged to the base 1-2. The base 1-2 is connected with a cable. The first output end of the cable is connected with the input end of the power transmission line system. The output end of the transmission line system is connected with a power grid. The power transmission line system comprises in particular an inverter 5 and a power transmission line 6. The first output of the cable is connected to the input of the inverter 5. The inverter 5 converts the direct current generated by the battery panel 1-1 into alternating current and boosts the voltage. The power transmission line 6 is connected to the output end of the inverter 5, and inputs high-voltage alternating current into the power grid.
The invention also provides an energy storage device 7-1, and a second output end of the cable is connected with an input end of the energy storage device 7-1. The output of the energy storage device 7-1 is connected with a drive assembly, i.e. a drive motor. Further, a second output terminal defining a cable line is connected to an input terminal of the energy storage device 7-1 via the relay 7-2. And, the relay 7-2 can be remotely controlled. In practical applications, the relay 7-2 may be remotely opened according to the electric energy consumption requirement, so that the energy storage device 7-1 is charged by the electricity generated by the battery panel 1-1.
The output end of the energy storage device 7-1 is connected with the driving motor through a power supply circuit. The power supply line is provided with a switch which is a remote control switch. When the solar energy storage device is in severe weather such as sand, dust, rain and snow, the solar energy storage device 7-1 is driven to provide forward electric energy for the driving motor without approaching the photovoltaic module system, and the switch is controlled remotely, so that the driving motor can rotate forward, and the electric telescopic shaft 2-1 is driven to extend, so that the battery plate 1-1 is folded. When the sand, dust, rain and snow weather passes, the switch is remotely controlled, so that the energy storage device 7-1 provides negative electric energy for the driving motor, and then the driving motor is reversed, so that the electric telescopic shaft 2-1 is driven to retract, and the battery plate 1-1 is unfolded.
