[0002] Distributed photovoltaic power generation is a new and promising method of power generation and comprehensive energy utilization.

DETAILED DESCRIPTION

[0027] Reference herein to an embodiment means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present invention. The appearance of such a phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0028] Existing distributed photovoltaic power generation devices usually require multiple photovoltaic panels to be installed in a flat and sufficient area. Although this installation method can ensure that the distributed photovoltaic power generation device has sufficient power generation in the area, in mountainous areas or areas with dense and cluttered obstacles, it is usually impossible to install a sufficient number of photovoltaic panels due to insufficient horizontal area, resulting in limited power generation of the photovoltaic power generation device.

[0029] A distributed photovoltaic power generation device, such as Figure 1-Figure 5 and Figure 11As shown, it includes: a base 1, the base 1 is fixedly connected to a symmetrically distributed support rod 2, the support rod 2 is provided with a first slide 201 and a second slide 202, and the support rod 2 is fixedly connected to a fixed shell 21; a photovoltaic bracket 3, having a plurality of longitudinally distributed ones, all of which are slidably connected between the symmetrically distributed support rods 2, the photovoltaic bracket 3 is provided with a first boss 301 and a raised portion, the raised portion of the photovoltaic bracket 3 is provided with a second boss 302, the first boss 301 slides in the first slide 201, and the second boss 302 slides in the second slide 202 ; The number of photovoltaic panels 4 is the same as the number of photovoltaic brackets 3, and they are rotatably connected to adjacent photovoltaic brackets 3 respectively; the power part 5 is installed on one of the support rods 2, and the power part 5 is equipped with an electric reel 51, and the electric reel 51 is wound with a first steel wire rope, and the first steel wire rope is fixed to the uppermost photovoltaic bracket 3; the pulling mechanism is arranged between the symmetrically distributed support rods 2, and is used to make the uppermost photovoltaic bracket 3 drive other photovoltaic brackets 3 to move together; the driving mechanism is arranged on the base 1, and is used to drive the support rod 2 to swing.

[0030] Furthermore, if Figure 5 As shown, an electronic wind vane 6 is installed at the top end of one of the support rods 2, and an acceleration detection sensor is installed inside the electronic wind vane 6.

[0031] Furthermore, if Figure 4 As shown, the first slideway 201 is a T-shaped slideway.

[0032] In the above solution, the base 1 has at least twice the weight of all other components of the device, which is used to control the center of gravity of the device to a position close to the base 1 to ensure the stability of the device. The first slide 201 is designed as a T-shaped slide, and the first boss 301 is designed as a boss with a circular plate (such as Figure 4 As shown), it is ensured that the photovoltaic bracket 3 can only slide up and down during the process of sliding up and down along the first slide 201, and will not tilt to the left or right. The photovoltaic panel 4 is electrically connected to the external power storage element, and the power piece 5, the electric reel 51, the electronic wind vane 6 and the driving mechanism are all electrically connected to the external control terminal. The power piece 5 is composed of a motor, a sprocket and a chain (refer to the existing electric flag raising device). The electric reel 51 has a self-locking function. The electronic wind vane 6 is used to detect the wind speed and wind direction at the top of the support pole 2. The acceleration detection sensor inside it is also an electronic device for detecting the amplitude of the swing of the support pole 2 under the action of wind. The number and size of the photovoltaic bracket 3 can be designed according to the specific situation. This solution is described as having a total of five photovoltaic brackets 3. When the photovoltaic bracket 3 is not in use, it is stacked at the lower part of the support pole 2 under the action of the lifting mechanism (as shown in FIG. Figure 11 As shown, at this time, the first steel wire rope on the electric reel 51 is in a fully stretched state).

[0033] The working principle of the above scheme is as follows: after the staff installs the device, all photovoltaic brackets 3 are initially in a horizontal state, the first steel wire rope is in a relaxed state, and the fixed connection point between the uppermost photovoltaic bracket 3 and the first steel wire rope is located at the rear side of the photovoltaic bracket 3. At this time, the staff first controls the electric reel 51 to reel in the first steel wire rope through the control terminal, and the first steel wire rope drags the rear side of the uppermost photovoltaic bracket 3 upward, so that the uppermost photovoltaic bracket 3 swings upward with the first protrusion 301 as the fulcrum, and the uppermost photovoltaic bracket 3 is gradually pulled from a horizontal state to a vertical state. When the uppermost photovoltaic bracket 3 is completely dragged to a vertical state, the second protrusion 302 on it is turned into the second slide 202. At this time, the first steel wire rope is completely reeled in, and then the control terminal controls The braking member 5 rotates to drag the uppermost photovoltaic bracket 3 to the top of the support rod 2. During the upward movement of the uppermost photovoltaic bracket 3, the photovoltaic bracket 3 below it is dragged in sequence from top to bottom by the pulling mechanism. When dragging the photovoltaic bracket 3, the pulling mechanism first drags the photovoltaic bracket 3 to a vertical state, and then drags the photovoltaic bracket 3 to a position close to the photovoltaic bracket 3 above it. When all photovoltaic brackets 3 are pulled up to a vertical state and two adjacent photovoltaic brackets 3 are close to each other, the control terminal turns off the power member 5. At this time, all photovoltaic brackets 3 are in use, and all photovoltaic panels 4 generate electricity together. The structure composed of the support rod 2, photovoltaic bracket 3 and photovoltaic panel 4 has the highest power generation efficiency and the largest wind-exposed area.

[0034] When the wind is strong, the support pole 2, photovoltaic bracket 3 and photovoltaic panel 4 will shake due to the large wind-exposed area. The electronic wind vane 6 and its internal acceleration detection sensor simultaneously detect the wind force and the shaking amplitude of the top of the support pole 2, and transmit the information to the control terminal. The control terminal evaluates the current stability of the device by analyzing the wind force information and the shaking amplitude of the top of the support pole 2, and compares the evaluated value with the value set by the staff (the staff sets the value according to the strength of the support pole 2. If the shaking amplitude of the top exceeds the value, it may affect the stability of the device). When the evaluated value is greater than the set value, the number of photovoltaic panels 4 that need to be suspended is immediately determined according to the shaking amplitude to ensure that the support pole 2, photovoltaic bracket 3 and photovoltaic panels 4 remain stable under the current wind force, so as to take into account the stability and power generation efficiency of the device. Take the need to suspend the use of the two photovoltaic panels 4 on the bottom as an example:

[0035] The control terminal controls the power part 5 to drive all photovoltaic brackets 3 and photovoltaic panels 4 to move downward. The photovoltaic bracket 3 on the lowermost side first moves to the lowermost side under the action of the lifting mechanism, and is gradually separated from the upper and adjacent photovoltaic bracket 3 under the drive of the lifting mechanism, and rotates from a vertical state to a horizontal state (the photovoltaic bracket 3 on the lowermost side gradually rotates to the initial state). The photovoltaic bracket 3 on the lowermost side is suspended. Then, the second photovoltaic bracket 3 from bottom to top is also driven by the lifting mechanism to move to the upper side of the lowermost photovoltaic bracket 3, and is turned to a horizontal state. At the same time, the use of the photovoltaic bracket 3 is suspended. Finally, the control terminal controls the power part 5 to stop working. At this time, only the three photovoltaic panels 4 on the upper side are working. Although the power generation efficiency is reduced, the windward area of ​​the structure composed of the support rod 2, photovoltaic bracket 3 and photovoltaic panel 4 is reduced, and the shaking amplitude of the support rod 2 under the action of wind is reduced, making the device more stable under strong winds.

[0036] When the wind stops for a certain period of time, the control terminal controls the power component 5 to drive all the photovoltaic brackets 3 to rise again, so that the photovoltaic panels 4 on the lower side can work again.

[0037] Furthermore, if Figure 4 、 Figure 7 and Figure 8 As shown, the pulling mechanism includes: a winding roller 7, the number of which is one less than the number of photovoltaic brackets 3, which are rotatably connected to adjacent photovoltaic brackets 3, and only the photovoltaic bracket 3 on the lowermost side is not rotatably connected with the winding roller 7, and the winding roller 7 is wound with a second steel wire rope, and the second steel wire rope is fixed to the lower and adjacent photovoltaic bracket 3, and the winding roller 7 is fixed with a rotating gear 8; a fixed bracket 9, fixed between the symmetrically distributed support rods 2, and the fixed bracket 9 is fixed with a fixed rack 10, and the fixed rack 10 is used to drive the rotating gear 8 to rotate; a locking assembly, arranged on the fixed bracket 9, for locking the winding roller 7; a storage assembly, arranged on the lower side of the symmetrically distributed support rods 2, for storing unused photovoltaic brackets 3.

[0038] Furthermore, the length of the second steel wire rope is greater than the height of the photovoltaic bracket 3 , and the length of the fixed rack 10 is greater than the height of the photovoltaic bracket 3 .

[0039] In the above scheme, except for the photovoltaic bracket 3 on the lowermost side, the four photovoltaic brackets 3 on the upper side are all rotatably connected to the winding roller 7, and the winding roller 7 pulls the lower and adjacent photovoltaic bracket 3 to move or rotate through the second steel wire rope. By making the length of the second steel wire rope greater than the height of the photovoltaic bracket 3, it is used to make the upper photovoltaic bracket 3 in a vertical state and the lower photovoltaic bracket 3 in a horizontal state when it is not pulled by the adjacent second steel wire rope. By making the length of the fixed rack 10 greater than the height of the photovoltaic bracket 3, the winding roller 7 and the rotating gear 8 move from the lower side of the fixed rack 10 to the upper side of the fixed rack 10, and the fixed rack 10 winds the second steel wire rope on the winding roller 7 from a completely relaxed state to a completely wound state.

[0040] The working principle of the above scheme is as follows: in the process of the control terminal dragging the uppermost photovoltaic bracket 3 upward through the power piece 5, the rotating gear 8 on the photovoltaic bracket 3 first contacts the fixed rack 10, and the locking assembly of the uppermost photovoltaic bracket 3 releases the lock of the adjacent rotating gear 8, and then the winding roller 7 and the rotating gear 8 rotate together along the fixed rack 10 during the upward movement, and the winding roller 7 reels the adjacent second steel wire rope, and the second steel wire rope drags the lower photovoltaic bracket 3 upward to swing the photovoltaic bracket 3 to a vertical state, and then the second steel wire rope drags the lower photovoltaic bracket 3 upward during the retraction process, so that the lower photovoltaic bracket 3 is moved from the storage When the assembly is pulled out, the distance between the two photovoltaic brackets 3 gradually decreases until the photovoltaic bracket 3 on the lower side contacts the photovoltaic bracket 3 on the uppermost side. At this time, the rotating gear 8 just breaks away from the contact with the fixed rack 10, and the locking assembly of the uppermost photovoltaic bracket 3 re-locks the adjacent rotating gear 8 to prevent the adjacent rotating gears 8 and the adjacent winding roller 7 from rotating freely. Then, the winding roller 7 on the second photovoltaic bracket 3 from top to bottom drags the lower and adjacent photovoltaic bracket 3 to a vertical state through the above principle and moves upward together until all photovoltaic brackets 3 are dragged to a vertical state, the control terminal turns off the power part 5, and the uppermost photovoltaic bracket 3 stops moving upward.

[0041] After the control terminal evaluates the stability of the device, when it is necessary to lower the two photovoltaic brackets 3 on the bottom, the control terminal controls the power part 5 to reverse, thereby causing the photovoltaic bracket 3 on the top to drive the other photovoltaic brackets 3 to move downward, and the rotating gear 8 on the second photovoltaic bracket 3 from bottom to top contacts and re-engages with the fixed rack 10 again, and the locking component on it releases the lock on the adjacent rotating gear 8, and then the second photovoltaic bracket 3 from bottom to top continues to move downward, and the rotating gear 8 on it drives the adjacent winding roller 7 to rotate, and the winding roller 7 releases the second wire rope on it, so that the lowest photovoltaic bracket 3 moves downward until the lowest photovoltaic bracket 3 enters the storage component, the lowermost photovoltaic bracket 3 stops moving downward, and the winding roller 7 on the second photovoltaic bracket 3 from bottom to top continues to release the second steel wire rope thereon, so that the upper part of the lowermost photovoltaic bracket 3 swings backward until the lowermost photovoltaic bracket 3 swings to a horizontal state. At this time, the locking component on the second photovoltaic bracket 3 from bottom to top re-locks the adjacent rotating gear 8, and the rotating gear 8 on the third photovoltaic bracket 3 from bottom to top contacts the fixed rack 10, and then the second photovoltaic bracket 3 from bottom to top moves according to the moving path of the lowermost photovoltaic bracket 3, and finally swings to a horizontal state. At this time, the control terminal turns off the power part 5.

[0042] Furthermore, if Figure 7 and Figure 8 As shown, the locking assembly includes: elastic telescopic rods 11, the number of which is the same as the number of winding rollers 7, which are respectively fixed to the photovoltaic brackets 3 close to the adjacent winding rollers 7, and the telescopic ends of the elastic telescopic rods 11 are fixed with locking parts 12, which are used to limit the rotation of the adjacent rotating gears 8; extrusion strips 13, which are fixed to the fixed bracket 9, and the extrusion strips 13 are used to squeeze the adjacent locking parts 12 to move.

[0043] In the above scheme, the contact point between the locking member 12 and the rotating gear 8 is a hexagonal prism structure, and the rotating gear 8 is provided with a limiting groove. When the rotating gear 8 is disengaged from the fixed rack 10, if the locking member 12 fails to align with the limiting groove of the rotating gear 8 in time, the rotating gear 8 cannot be limited. At this time, the rotating gear 8 only needs to rotate a small angle to align the locking member 12 with the limiting groove of the rotating gear 8 again, so that the locking member 12 is inserted into the limiting groove of the rotating gear 8 to limit the rotating gear 8, thereby increasing the adaptability of the device to different situations. The length of the extrusion strip 13 is not less than the length of the fixed rack 10, and is used for the period when the rotating gear 8 is engaged with the fixed rack 10. The locking member 12 will not limit the rotating gear 8, and therefore will not hinder the rotation of the adjacent rotating gear 8.

[0044] The above working principle is as follows: in the process of the photovoltaic bracket 3 driving the adjacent rotating gear 8 and the adjacent locking member 12 to move from top to bottom, the locking member 12 first contacts the extrusion bar 13. As the locking member 12 moves, the locking member 12 is squeezed by the extrusion bar 13 and moves laterally. The locking member 12 releases the limit on the rotating gear 8, and the elastic telescopic rod 11 is compressed and stored. Then, the rotating gear 8 is meshed with the fixed rack 10. The photovoltaic bracket 3 continues to drive the rotating gear 8 and the locking member 12 to move downward. The locking member 12 slides along the extrusion bar 13. When the rotating gear 8 moves to the point where it is disengaged from the fixed rack 10, When the locking member 12 is in the position, the extrusion bar 13 stops squeezing the adjacent locking member 12, and the locking member 12 is reset under the elastic force of the elastic telescopic rod 11 and contacts the rotating gear 8. At this time, if the limiting grooves of the locking member 12 and the rotating gear 8 are aligned, the locking member 12 is directly inserted into the limiting groove of the rotating gear 8 to limit the rotating gear 8. If the limiting grooves of the locking member 12 and the rotating gear 8 are not completely aligned, the rotating gear 8 rotates freely. When the limiting groove on the rotating gear 8 rotates to a position aligned with the locking member 12, the locking member 12 is directly inserted into the limiting groove of the rotating gear 8 to limit the rotating gear 8.

[0045] Furthermore, if Figure 3 、 Figure 9 and Figure 10 As shown, the storage assembly includes: two symmetrically distributed fixing plates 14, which are respectively fixed to the lower parts of adjacent support rods 2; receiving members 15, which have two rows, and each row of receiving members 15 is respectively arranged on adjacent fixing plates 14, and the number of receiving members 15 in each row is consistent with the number of photovoltaic brackets 3, and the receiving members 15 are used to receive adjacent first bosses 301, and the fixing shell 21 is used to receive adjacent second bosses 302.

[0046] Furthermore, if Figure 9 As shown, the receiving member 15 includes: a receiving frame 151, which is rotatably connected to the adjacent fixed plate 14, and a torsion spring is installed between the two. Except for the receiving frame 151 on the lowermost side, the other receiving frames 151 are slidably connected to the receiving rod 16, and the receiving rod 16 is in contact with the lower and adjacent receiving frame 151, and a tension spring is installed between the receiving rod 16 and the adjacent receiving frame 151.

[0047] In the above solution, the number of receiving members 15 is ten, and they are respectively installed on adjacent support rods 2 in a bilaterally symmetrical distribution. The shape of the fixing plate 14 is as follows: Figure 2As shown, the receiving member 15 is located on the side of the adjacent support rod 2 close to the first slide 201, and is used to receive the adjacent first boss 301. The fixing shell 21 is located on the side of the adjacent support rod 2 close to the second slide 202, and is used to receive the adjacent second boss 302. The distance between the two adjacent receiving frames 151 and the rotating connection of the fixing plate 14 is greater than the thickness of the photovoltaic bracket 3, so that when the two adjacent photovoltaic brackets 3 are in a horizontal state, there is always a gap on the front sides of the two photovoltaic brackets 3 to prevent the two adjacent photovoltaic panels 4 from being squeezed and damaged. A groove is provided on the upper side of the photovoltaic bracket 3, and the groove of the photovoltaic bracket 3 is used to limit the raised part of the photovoltaic bracket 3. The depth of the groove on the photovoltaic bracket 3 is less than the raised height of the raised part of the photovoltaic bracket 3, so that when the two adjacent photovoltaic brackets 3 are in a horizontal state, there is always a gap on the rear sides of the two photovoltaic brackets 3, and the tension spring on the receiving rod 16 is always in a stored force state, used to ensure that the receiving rod 16 is always in contact with the receiving frame 151 on its lower side.

[0048] The working principle of the above scheme is as follows: after the control terminal evaluates the stability of the device, during the process of lowering the two photovoltaic brackets 3 on the lower side, when the photovoltaic bracket 3 on the lower side slides to the lower side of the first slide 201, the first protrusion 301 just contacts the lowermost receiving frame 151, the second protrusion 302 is located at the lower part of the second slide 202, and the second protrusion 302 is located in the fixed shell 21, the first protrusion 301 enters the lowermost receiving frame 151, and the lowermost receiving frame 151 is in contact with the first protrusion 301. 1 is squeezed by the gravity of the lowest photovoltaic bracket 3 and swings downward. At this time, the receiving rod 16 on the second receiving frame 151 from bottom to top extends backward under the action of the tension spring, so that the receiving rod 16 is always in contact with the lowest receiving frame 151, which is convenient for receiving the second photovoltaic bracket 3 from bottom to top. When the lowest receiving frame 151 swings, it drives the torsion spring on it to twist and store force until the lowest receiving frame 151 contacts the first slide 201, the lowest receiving frame 151 stops rotating, and the lowest photovoltaic bracket After the second photovoltaic bracket 3 is lowered, the first protrusion 301 on it enters the second receiving frame 151 and the receiving rod 16 and falls into the second receiving frame 151 from the bottom to the top. After the second photovoltaic bracket 3 is lowered, the first protrusion 301 on it enters the second receiving frame 151 from the bottom to the top and falls into the second receiving frame 151 from the bottom to the top under the guidance of the receiving rod 16. After the second photovoltaic bracket 151 from the bottom to the top also receives the upper photovoltaic bracket 3, the upper part of the receiving frame 151 swings downward under the gravity of the photovoltaic bracket 3, so that the third receiving frame 151 from the bottom to the top receives the photovoltaic bracket 3 on the upper side. The second photovoltaic bracket 3 from the bottom to the top then swings to the horizontal state according to the same steps. At this time, there is always a gap between the two photovoltaic brackets 3 on the lower side.

[0049] Furthermore, if Figures 1-4 、 Figure 6 and Figure 11 As shown, the driving mechanism includes: a rotating shaft 22, which is rotatably connected to the base 1, and a symmetrically distributed first electric telescopic rod 23 is fixed to the rotating shaft 22, and the telescopic end of the first electric telescopic rod 23 is rotatably connected to the adjacent fixed shell 21; the number of second electric telescopic rods 31 is equal to the number of photovoltaic brackets 3, and they are respectively fixed to adjacent photovoltaic brackets 3, and the telescopic ends of the second electric telescopic rods 31 are rotatably connected to the connecting rods 32, and the connecting rods 32 are rotatably connected to the adjacent photovoltaic panels 4.

[0050] In the above scheme, the first electric telescopic rod 23 and the second electric telescopic rod 31 are both electrically connected to the control terminal. The control terminal controls the first electric telescopic rod 23 to extend or retract, thereby controlling the two support rods 2 to swing relative to the base 1, thereby enabling the device to adapt to the lighting conditions in different latitudes (for example, in areas close to the equator, it is necessary to control the two support rods 2 to swing to an inclined state to prevent the upper photovoltaic panel 4 from blocking the light-receiving area of ​​the lower photovoltaic panel 4). When the control terminal controls the telescopic end of the second electric telescopic rod 31 to retract, the telescopic end of the second electric telescopic rod 31 drives the connecting rod 32 When the second electric telescopic rod 31 is extended by the control terminal, the telescopic end of the second electric telescopic rod 31 drives the adjacent photovoltaic panel 4 to swing downward and reset by the opposite principle, thereby adjusting the upward tilt angle of the adjacent photovoltaic panel 4 relative to the adjacent photovoltaic bracket 3 to ensure that the photovoltaic panel 4 is as vertical as possible to the sunlight, thereby improving the photovoltaic power generation efficiency of the photovoltaic panel 4, and when the photovoltaic panel 4 is no longer in use, the photovoltaic panel 4 is controlled to swing into the adjacent photovoltaic bracket 3 to facilitate the storage of the photovoltaic bracket 3.

[0051] Furthermore, if Figure 1-Figure 3 As shown, it also includes: a protection component, which is arranged on the base 1 and is used to protect the unused photovoltaic panels 4. The protection component includes: a protection shell 17, which is installed on the base 1; and a protection plate 18, which is fixed to the base 1.

[0052] In the above scheme, the protective shell 17 is a folding shell with an electric shaft installed. The electric shaft on the protective shell 17 is electrically connected to the control terminal. A groove is provided on the protective shell 17, and the size of the groove is larger than the diameter of the second steel wire rope to prevent the protective shell 17 and the protective plate 18 from clamping the second steel wire rope between the unused photovoltaic bracket 3 on the lower side and the upper photovoltaic bracket 3 when the protective shell 17 is closed. When it is necessary to control the horizontal photovoltaic bracket 3 to be pulled up or lowered, the control terminal first controls the rotation of the protective shell 17 to avoid the protective shell 17 blocking the moving path of the photovoltaic bracket 3. When the control terminal stops controlling the movement of the photovoltaic bracket 3, the control terminal controls the protective shell 17 to rotate to Figure 1 In the horizontal state, the protective shell 17 and the protective plate 18 jointly provide protection for the non-working photovoltaic bracket 3 on the lower side to prevent the non-working photovoltaic bracket 3 from being damaged by wind and sand (when the wind and sand are strong, all photovoltaic brackets 3 can also be retracted to a horizontal state to protect all photovoltaic brackets 3).

[0053] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications may be made to the present invention without departing from the principles and spirit of the present invention. Therefore, the detailed description of the embodiments of the present disclosure is intended to be illustrative only and not to limit the present invention.
