The Chinese patent with application number 202011180303.8 also discloses a photovoltaic module focusing device, which relates to the field of photovoltaic module technology, in order to solve the problem that the existing photovoltaic module always rotates the photovoltaic module when concentrating, causing the photovoltaic module to be worn and easily damaged. Fixed concentrating plates are provided at the front and rear ends of the photovoltaic module body, and a movable concentrating plate is provided below the photovoltaic module body. The concentrating plate is curved and located on both sides of the photovoltaic panel. After the light is irradiated on the concentrating plate, it is reflected on the photovoltaic panel to form a concentrated light, thereby improving the absorption rate of light energy.

[0003] The above existing technologies have the following defects: the cleaning plate needs to reach from one end of the photovoltaic panel to the other end, the cleaning plate has a long stroke, the motor rotation time is long, and the energy consumption is high. When strong wind blows onto the concentrator, the curved space between the photovoltaic panel surface forms a strong air pressure that acts on the photovoltaic panel, causing the photovoltaic panel to bear a large load, affecting the structural strength.

[0006] As a further preferred embodiment, the driving mechanism also includes gears fixed on both ends of the screw rod, and also includes a toothed belt fixed on both ends of the focusing plate, the toothed belt is arranged on the inner surface of the focusing plate along the bending direction of the focusing plate, and the toothed belt is meshed on the gears.

[0007] As a further preference, the focusing plate is composed of a rubber plate and a focusing mirror attached to the rubber plate, and the focusing mirror is a matrix of multiple focusing mirror units hinged together, so that the focusing plate can be flexibly deformed when being dragged into the assembly cavity by the folding frame.

[0008] As a further preferred embodiment, a connecting rod is welded in the assembly cavity, the electric cylinder is on the connecting rod, and two ends of the connecting rod are connected to two ends of the assembly cavity.

[0009] As a further preferred embodiment, the folding frame includes two folding rods hinged together, and a pull plate is installed at each end of the two focusing plates extending into the assembly cavity. The other ends of the two folding rods are tilted to both sides and then transferred to the pull plates of the two focusing plates. The folding frame also includes a pressure rail fixed on the two folding rods, and a pull rod connected to the electric cylinder actuating rod. The end of the pull rod is connected to a pressure frame, and the pressure frame is U-shaped.

There are two sensors, one close to the concentrating plate on the left, and the other close to the concentrating plate on the right, and the detection probes of the sensors are both located in the curved space of the concentrating plate, and the sensors are electrically connected to the controller.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] When strong wind blows onto the concentrator or photovoltaic panel, the electric cylinder is started, and the action rod of the electric cylinder extends outward and drags the folding frame, so that the two folding ends of the folding frame are folded at the same time, and the two concentrators are dragged into the assembly cavity from both sides at the same time; when the folding frame is folded, the two concentrators are dragged into the assembly cavity along the two notches for automatic protection. When strong wind blows onto the photovoltaic panel, the two sides of the photovoltaic panel are directly exhausted, and the wind force will not be concentrated due to the existence of the concentrator and the focusing area, ensuring that the photovoltaic panel and the concentrator are not easy to deform. The toothed belt will mesh with the gear to rotate before it is dragged and straightened into the assembly cavity with the concentrator, and the gear drives the screw to rotate, and the screw drives the two sections of the external threads in opposite directions to rotate, and the two sections of the external threads in opposite directions drive the two cleaning rods to move toward each other. Since the two cleaning rods are located on the photovoltaic panel, and the inner surfaces of the two cleaning rods are in contact with the photovoltaic panel, when the two cleaning rods move toward each other, it is equivalent to carrying out a cleaning operation for the dust attached to the photovoltaic surface.

[0015] When strong winds hit the concentrating panels and photovoltaic panels, the two concentrating panels can not only be stored in the assembly cavity for self-protection, but can also be linked with the cleaning rod to perform a cleaning operation on the photovoltaic surface of the photovoltaic panel, thereby solving the two problems raised in the background technology. The cleaning rods are two rods that move in opposite directions, so a small stroke can complete the cleaning operation on the photovoltaic surface, and as the concentrating panels are extended and stored, the two cleaning rods can complete two cleaning operations, replacing the motor-driven method, reducing losses while achieving two functions.

DETAILED DESCRIPTION

[0024] The above and other embodiments and advantages of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0025] In one embodiment, Figure 1-Figure 7 As shown:

[0026] The present embodiment provides a full-screen concentrated photovoltaic assembly, including a frame 1, a photovoltaic panel 2 is installed on the top of the frame 1, an assembly cavity 3 with an opening facing downward is provided at the bottom of the frame 1, and slots 4 are provided on the left and right sides of the frame 1, and a concentrating plate 5 is installed in each of the two slots 4, one end of the concentrating plate 5 extends into the assembly cavity 3, and the other end of the concentrating plate 5 penetrates to the side of the frame 1 and bends upward above the top surface of the photovoltaic panel 2, and a concentrating area 6 is formed between the two concentrating plates 5 and the top surface of the photovoltaic panel 2;

[0027] A driving mechanism 7 is provided in the assembly chamber 3. The driving mechanism 7 includes an electric cylinder 8 fixed in the assembly chamber 3, and also includes a folding frame 9 connected to the action rod of the electric cylinder 8. The two folding ends of the folding frame 9 are respectively connected to one end of the two focusing plates 5 extending into the assembly chamber 3; when the folding frame 9 is folded, the focusing plates 5 can be pulled into the assembly chamber 3;

[0028] A bearing seat 10 is installed at each of the upper and lower ends of the top surface of the frame 1, and a screw rod 11 is installed between the two bearing seats 10. The upper and lower ends of the screw rod 11 are provided with external threads 12 in opposite directions to each other. A cleaning rod 13 is installed on each of the upper and lower external threads 12 in opposite directions of each other of the screw rod 11. When the screw rod 11 rotates with two sections of external threads 12 in opposite directions of each other, the two cleaning rods 13 can move toward or in opposite directions, and the two cleaning rods 13 contact the top surface of the photovoltaic panel 2;

[0029] When the focusing plate 5 is pulled into the assembly cavity 3 , the screw 11 is driven to rotate; a guide rod 23 symmetrically on the other side of the screw 11 is also installed on the top surface of the frame 1 , and the other ends of the two cleaning rods 13 are slidably fitted on the two guide rods 23 .

[0030] The photovoltaic panel 2 is fixed on the frame 1, and the back of the frame 1 is fixed to the building through a construction frame, so that the photovoltaic panel 2 can be displayed under bright light and absorb energy in real time. Since a focusing area 6 is formed between the curved sides of the two focusing plates 5 and the top surface of the photovoltaic panel 2, when light is irradiated onto the photovoltaic panel 2 and absorbed by the photovoltaic panel 2, the light will also be reflected onto the focusing plate 5 through the photovoltaic panel 2, and then reflected and focused by the focusing plate 5 and reflected onto the photovoltaic panel 2. A large number of conical or diamond-shaped reflectors are glued to the reflective surface of the focusing plate 5 (the side facing the focusing area 6), so that the reflected light can be focused and then reflected onto the photovoltaic panel 2 to complete multiple energy absorption conversions, thereby improving the conversion efficiency of light energy into electrical energy.

[0031] The focusing plate 5 in the present invention is curved in order to better focus the light on the photovoltaic panel 2. In addition, due to its curved shape, when strong wind comes, the focusing plate 5 will not cause strong wind to gather in the focusing area 6, causing the photovoltaic panel 2 or the focusing plate 5 to break or deform due to the impact of strong wind. When strong wind blows onto the focusing plate 5 or the photovoltaic panel 2, the electric cylinder 8 is started, and the action rod of the electric cylinder 8 extends outward and drags the folding frame 9, so that the two folding ends of the folding frame 9 are folded at the same time, and at the same time, the two focusing plates 5 are dragged into the assembly cavity 3 from both sides; when the folding frame 9 is folded, the two focusing plates 5 are dragged into the assembly cavity 3 along the two notches 4 at the same time, and the parts of the two focusing plates 5 pulled into the assembly cavity 3 are gradually straightened, and the parts not pulled into the assembly cavity 3 are still bent. The electric cylinder 8 can be started by a manual button or by remote control. A wind detection device can also be installed on the frame 1 or the building. When the wind detection device detects the wind strength, for example, when the wind is above level 7, it sends a command to the electric cylinder 8 to make it move, and drives the folding frame 9 to fold, so that the two focusing plates 5 are automatically stored in the assembly cavity 3. This remote control or remote control method is a prior art. The present invention protects the device component itself, and this remote control core technology will not be described in detail.

[0032] In continuation of the above, since the driving mechanism 7 also includes gears 14 fixed on both ends of the screw 11, and also includes toothed belts 15 fixed on both ends of the focusing plate 5, and the toothed belts 15 are arranged on the focusing plate 5 along the curved contour of the focusing plate 5, and the toothed belts 15 are meshed on the gears 14, that is, the toothed belts 15 are made of flexible material, and the portion of the toothed belts 15 that follows the focusing plate 5 being pulled into the assembly chamber 3 is straightened, and the portion of the focusing plate 5 that is not pulled into the assembly chamber 3 is still bent, and the toothed belts 15 mesh with the gears 14 to rotate before being dragged and straightened by the focusing plate 5 into the assembly chamber 3, and the screw 11 is driven by the gears 14 to rotate, and the screw 11 drives the two sections of the outer The thread 12 rotates, and the two sections of external threads 12 in opposite directions respectively carry the two cleaning rods 13 to move toward each other. Since the two cleaning rods 13 are located on the photovoltaic panel 2, and the inner surfaces of the two cleaning rods 13 are in contact with the photovoltaic panel 2, when the two cleaning rods 13 move toward each other, it is equivalent to carrying out a cleaning operation on the dust attached to the photovoltaic surface. At this time, the focusing plate 5 is dragged into the assembly cavity 3, and the focusing area 6 that is easy to form wind force has disappeared at this time. When strong wind blows onto the photovoltaic panel 2, the two sides of the photovoltaic panel 2 are directly exhausted, and wind force concentration will not be formed due to the existence of the focusing plate 5 and the focusing area 6, thereby ensuring that the photovoltaic panel 2 and the focusing plate 5 are not easily deformed.

[0033] Of course, after the strong wind disappears, the action rod of the control electric cylinder 8 automatically retracts, and at this time, the two ends of the folding frame 9 change from folding to expanding to both sides. The two ends of the folding frame 9 push the two focusing plates 5 outward due to the expansion movement, and the outer ends of the two focusing plates 5 extend out of the frame 1 along the two notches 4. Then, by utilizing the performance characteristics of the plastic recovery of the focusing plates 5, after the bending is restored, a focusing area 6 is formed on both sides of the photovoltaic panel 2, and the focusing effect of the photovoltaic panel 2 is restored. When the two focusing plates 5 extend outward while restoring the bending, the toothed belt 15 meshes with the gear 14 to rotate in the opposite direction, and the gear 14 drives the screw 11 to rotate in the opposite direction, and the screw 11 drives the two sections of the opposite external threads 12 to rotate in the opposite direction, and the two sections of the opposite external threads 12 drive the two cleaning rods 13 to move in the opposite direction, which is equivalent to once again cleaning the dust attached to the photovoltaic surface.

[0034] From the above, it can be seen that when strong winds attack the concentrating panels 5 and the photovoltaic panels 2, the two concentrating panels 5 can not only be stored in the assembly cavity 3 for self-protection, but can also be linked with the cleaning rod 13 to perform a cleaning operation on the photovoltaic surface of the photovoltaic panel 2, thereby solving the two problems raised in the background technology. The cleaning rods 13 are two rods that move in opposite directions, so a small stroke can complete the cleaning operation of the dust on the photovoltaic surface, and with the extension and storage of the concentrating panel 5, the two cleaning rods 13 can complete two cleaning operations, replacing the motor-driven method, reducing losses while achieving two functions (cleaning of the photovoltaic panel 2 and windproof storage of the concentrating panel 5).

[0035] like Figures 1 to 3 As shown, it needs to be further explained that: the focusing plate 5 mentioned in the present invention is composed of a rubber plate 51 and a focusing lens 52, the focusing lens 52 is attached to the rubber plate 51, and the focusing lens 52 faces the focusing area 6, and in order to enable the curved focusing plate 5 to automatically plastically deform when being dragged into the assembly cavity 3, these focusing lenses 52 are hinged together by a matrix of multiple focusing lens 52 units, so that when the folding frame 9 is folded, the focusing plate 5 can be dragged into the assembly cavity 3.

[0036] A connecting rod 16 is welded in the assembly cavity 3 , the electric cylinder 8 is fixed on the connecting rod 16 , and two ends of the connecting rod 16 are connected to two ends of the assembly cavity 3 .

[0037] like Figures 4 to 6As shown, the structure of the folding frame 9 is as follows: it includes two folding rods 17 hinged together, one end of the two focusing plates 5 extending into the assembly chamber 3 is respectively installed with a pull plate 53, the other ends of the two folding rods 17 are tilted to both sides and then transferred to the pull plates 53 of the two focusing plates 5, the folding frame 9 also includes a pressure rail 18 fixed on the two folding rods 17, and also includes a pull rod 19 connected to the action rod of the electric cylinder 8, the end of the pull rod 19 is connected to a pressure frame 20, the pressure frame 20 is U-shaped, and a pressure roller 21 is installed on each side of the U-shaped pressure frame 20, and the two pressure rollers 21 are respectively rolled on the two pressure rails 18. A bending spring 22 is respectively connected to the two folding rods 17 of the folding frame 9, and the two bending springs 22 are respectively located on both sides of the two pressure rollers 21, and the other ends of the two bending springs 22 are respectively connected to the top inner surface of the assembly chamber 3.

[0038] When the action rod of the electric cylinder 8 pulls the pull rod 19 to move, the pull rod 19 pushes the pressing frame 20, so that the two ends of the pressing frame 20 with the pressure rollers 21 are away from the two pressure rails 18, and the pressure on the two pressure rails 18 gradually disappears. At this time, the two bending springs 22 rebound and shorten, and at the same time, the two folding rods 17 expand in opposite directions, and at the same time, the two focusing plates 5 are pushed outward along the two notches 4 through the two pull plates 53; on the contrary, when the action rod of the electric cylinder 8 drags the pull rod 19, the pull rod 19 drags the pressing frame 20, so that the two ends of the pressing frame 20 with the pressure rollers 21 forcefully roll the two pressure rails 18, and the pressure on the two pressure rails 18 gradually increases, and pushes the two folding rods 17 to rotate relative to each other, and at the same time, the two focusing plates 5 are dragged into the assembly cavity 3 along the two notches 4 through the two pull plates 53, and the two bending springs 22 are forced to lengthen. The folding and expansion of the folding frame 9 is controlled by the pressure roller 21 rolling the pressure rail 18, and the action is smoother.

[0039] The pressing frame 20 is located in the assembly cavity 3, and the maximum stroke of the pressing frame 20 will not exceed the assembly cavity 3. Therefore, during actual assembly, a cover plate will be installed on the frame 1 to cover the assembly cavity 3 and cover the above-mentioned components in the assembly cavity 3 in the assembly cavity 3.

[0040] The present invention also provides a full-screen concentrated photovoltaic system, including a sensor 24 and a controller 25. The sensor 24 is fixed on the frame 1. The sensor 24 is on the same side as the photovoltaic panel 2. The sensor 24 is in two locations, one close to the left concentrating plate 5 and the other close to the right concentrating plate 5. The detection probes of the sensor 24 are both located in the curved space of the concentrating plate 5. The sensor 24 is electrically connected to the controller 25.

[0041] The above orientation designations do not represent the specific orientations of the components in this implementation scheme. This implementation scheme is only for the convenience of describing the scheme, and the orientations are described relatively with reference to the figures. In essence, the specific orientations of the components are described according to their actual installation and actual use as well as the customary orientations of technicians in this field. This is hereby explained.

[0042] The specific implementation methods described above further describe the invention purpose, technical solutions, and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the protection scope of the present invention. It is particularly pointed out that for those skilled in the art, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
