[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] The core of the present invention is to provide an iron tower photovoltaic power generation device, which is not easily damaged by wind and has a long service life.

[0031] It should be noted that in the present embodiment, the orientation or position relationship indicated by "upper", "lower", etc. is based on the orientation or position relationship shown in the accompanying drawings, and is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0032] Please refer to Figure 1 and Figure 3 The present application provides a specific embodiment of an iron tower photovoltaic power generation device, including a photovoltaic panel group, a driver group, a wind speed sensor 6 and a controller.

[0033] The photovoltaic panel group includes a plurality of photovoltaic panels 3 , which can be rotatably arranged on the outer periphery of the iron tower 1 and arranged at intervals along the circumference of the iron tower 1 , and the plurality of photovoltaic panels 3 are all arranged to be tilted outward from top to bottom.

[0034] It should be noted that the number of photovoltaic panels 3 in the photovoltaic panel group is not limited, and can be selectively set according to actual needs. Several photovoltaic panels 3 are arranged around the circumference of the iron tower 1. Even if several photovoltaic panels 3 in the photovoltaic panel group are located at the same height, the occupied space can be reduced, which is conducive to the subsequent arrangement of multiple groups of photovoltaic panel groups. In addition, several photovoltaic panels 3 are rotatably connected to the iron tower 1, so that the photovoltaic panels 3 have the freedom to move closer to the iron tower 1, and in the working state, several photovoltaic panels 3 are tilted outward from top to bottom at a certain angle, so that several photovoltaic panels 3 in the photovoltaic panel group are arranged in an umbrella shape on the periphery of the iron tower 1, thereby increasing the surface area of ​​the photovoltaic panels 3 that capture solar radiation, thereby improving the absorption efficiency of the photovoltaic panels 3 to solar energy, that is, improving the conversion efficiency of solar energy.

[0035] The driver group includes a plurality of drivers 5 , which are all arranged on the iron tower 1 and correspondingly connected to a plurality of photovoltaic panels 3 , and are used to drive the corresponding photovoltaic panels 3 to rotate and approach the iron tower 1 .

[0036] It should be noted that a group of photovoltaic panels needs to correspond to a group of driver groups. Several drivers 5 in the driver group are connected to corresponding photovoltaic panels 3 in the photovoltaic panel group. Since several photovoltaic panels 3 in the photovoltaic panel group are arranged in an umbrella shape, each driver 5 drives the corresponding photovoltaic panel 3 to rotate toward the tower 1, so that the umbrella-shaped photovoltaic panel group can be folded. At this time, the effective area of ​​the photovoltaic panel 3 in contact with the sun is reduced, and the photovoltaic panel group is in a windproof state.

[0037] The wind speed sensor 6 is arranged on the iron tower 1 and is arranged adjacent to the photovoltaic panel group; the controller is arranged on the iron tower 1 and is electrically connected to the wind speed sensor 6 and each driver 5 .

[0038] It should be noted that the wind speed sensor 6 can monitor the wind speed near the photovoltaic panel group in real time and transmit it to the controller. The controller is set with the maximum wind speed that the photovoltaic panel 3 can withstand. When the real-time wind speed obtained by the controller exceeds the maximum wind speed that the photovoltaic panel 3 can withstand, the controller can transmit a retraction instruction to each driver 5, and each driver 5 drives the corresponding photovoltaic panel 3 to rotate and move closer to the iron tower 1, which can reduce the wind-receiving area of ​​the photovoltaic panel 3, thereby reducing the wind pressure on the photovoltaic panel 3, and thus avoiding the situation where the photovoltaic panel 3 is tilted, deformed, cracked and falls off due to excessive wind speed, so that the iron tower photovoltaic power generation device has wind resistance and is not easily damaged by wind.

[0039] Based on the above examples, please refer to Figure 1 and Figure 3 The photovoltaic panel groups are set to at least two groups and are spaced apart and arranged in an umbrella shape along the axial direction of the iron tower 1, and the drive groups are also set to at least two groups.

[0040] Take two groups of photovoltaic panels and two groups of driver groups as an example for explanation. Specifically, the two groups of photovoltaic panels are arranged at intervals along the axial direction of the iron tower 1, even if there are two layers of photovoltaic panel groups on the iron tower 1, to provide sufficient installation space for the photovoltaic panels 3 in the two groups of photovoltaic panel groups. The minimum distance between each photovoltaic panel 3 in the lower photovoltaic panel group and the iron tower 1 is not less than the maximum distance between each photovoltaic panel 3 in the upper photovoltaic panel group and the iron tower 1, so that the upper photovoltaic panel group and the lower photovoltaic panel group are arranged in an umbrella shape to avoid the upper photovoltaic panel group shielding the lower photovoltaic panel group and affecting the lower photovoltaic panel group to absorb solar energy. In addition, it is not difficult to understand that increasing the number of photovoltaic panel groups, that is, increasing the number of photovoltaic panels 3, can increase the absorption of solar energy, thereby increasing the total power generation of the photovoltaic power generation device. It should be noted that since one group of photovoltaic panel groups corresponds to one group of driver groups, the number of driver groups set must be consistent with the number of photovoltaic panel groups set.

[0041] Based on the above examples, please refer to Figure 1 and Figure 3 The wind speed sensor 6 is located at the upper end of the uppermost photovoltaic panel group.

[0042] It can be understood that the higher from the ground, the greater the wind speed. Therefore, the wind speed sensor 6 is set at the upper end of the photovoltaic panel group adjacent to the top layer to monitor the maximum wind speed near the iron tower photovoltaic power generation device, and transmit it to the controller as the real-time wind speed borne by the iron tower photovoltaic power generation device. This can better timely retract each group of photovoltaic panels before the real-time wind speed reaches the maximum wind speed that the photovoltaic panel 3 can withstand, so as to ensure that each photovoltaic panel 3 is not damaged.

[0043] It should be noted that the photovoltaic panel 3 is mainly divided into a rigid photovoltaic panel 3 and a flexible photovoltaic panel 3, wherein the rigid photovoltaic panel 3 is usually made of tempered glass and has extremely high durability and stability; the flexible photovoltaic panel 3 is composed of resin-encapsulated amorphous silicon as the main photoelectric element layer, which is laid flat on a base plate made of flexible material.

[0044] Please refer to Figure 1 and Figure 2 When the photovoltaic panel 3 is a rigid photovoltaic panel 3, in the first embodiment, the iron tower 1 is axially spaced and sleeved with two brackets 2 corresponding to the photovoltaic panel group, the upper bracket 2 is provided with a plurality of connecting rods 4, and the plurality of connecting rods 4 are rotatably connected to the upper ends of the plurality of photovoltaic panels 3, and the lower bracket 2 is provided with a driver group, in which the telescopic shafts 51 of the plurality of drivers 5 are connected to the lower ends of the plurality of photovoltaic panels 3.

[0045] Specifically, each photovoltaic panel group corresponds to two brackets 2, and the two brackets 2 are spaced apart and sleeved on the iron tower 1. The bracket 2 is preferably a circular platform to better support the plurality of photovoltaic panels 3 arranged circumferentially around the iron tower 1. The upper bracket 2 is provided with a plurality of connecting rods 4 that are rotatably connected to the upper ends of the plurality of photovoltaic panels 3 in a one-to-one correspondence. The plurality of drivers 5 in the driver group are all selected as telescopic motors and are all arranged on the lower bracket 2, and the telescopic shafts 51 of the plurality of telescopic motors are connected to the lower ends of the plurality of photovoltaic panels 3 in a one-to-one correspondence. In this way, when the photovoltaic panel group needs to be opened, the telescopic shafts 51 of each driver 5 extend outward, so that each photovoltaic panel 3 is tilted outward at a certain angle from top to bottom, and the photovoltaic power generation device is in a normal working state; when the photovoltaic panel group needs to be closed, the telescopic shafts 51 of each driver 5 retract, so that each photovoltaic panel 3 moves closer to the iron tower 1, and the photovoltaic power generation device is in a windproof state.

[0046] Preferably, the upper end of each photovoltaic panel 3 is connected to two symmetrical connecting rods 4 , and the lower end is connected to two symmetrical drivers 5 , which can improve the structural stability of the photovoltaic panel 3 .

[0047] Based on the first embodiment, please refer to Figure 1 Each photovoltaic panel 3 is provided with a solar tracker 7 which is electrically connected to the controller. In this way, when the photovoltaic power generation device is in normal working state, the solar tracker 7 can sense the direction and altitude of the sun in real time and transmit it to the controller. The controller can control the driver 5 to always face the photovoltaic panel 3 to the sun, thereby maximizing the absorption of sunlight and improving the photoelectric conversion efficiency.

[0048] Based on the first embodiment, please refer to Figure 1The connecting rod 4 includes a vertical rod section and an oblique rod section connected in one piece. The vertical rod section is vertically arranged on the upper bracket 2. The oblique rod section and the telescopic shaft 51 of the driver 5 are parallel to each other and are both inclined upward at a certain angle. In this way, the upper and lower two-point support can stably install the photovoltaic panel 3 on the bracket 2 of the iron tower 1, not easy to tilt, and can also reduce the thrust of the driver 5 to a certain extent.

[0049] On the basis of the first embodiment, a rotating member is provided between the connecting rod 4 and the upper end of the photovoltaic panel 3, and the rotating member includes a first connecting portion provided on the photovoltaic panel 3, a second connecting portion provided on the connecting rod 4 and a rotating shaft 54 ​​hinged between the two, and the rotating shaft 54 ​​is arranged in a direction perpendicular to the axial direction of the tower 1.

[0050] It should be noted that the rotating member can adopt a hinge structure, and the rotating member includes a first connection part, a second connection part and a rotating shaft 54. The first connection part and the second connection part are hinged through the rotating shaft 54, so that the first connection part can rotate relative to the second connection part around the rotating shaft 54. Therefore, the first connection part is fixed on the photovoltaic panel 3, and the second connection part is fixed on the inclined rod section of the connecting rod 4. In this way, the telescopic shaft 51 of the driver 5 retracts, which can drive the photovoltaic panel 3 to rotate relative to the connecting rod 4 around the rotating shaft 54. Since the rotating shaft 54 ​​is arranged in a direction perpendicular to the axial direction of the iron tower 1, the photovoltaic panel 3 rotates toward the iron tower 1.

[0051] Please refer to Figure 3 and Figure 4 When the photovoltaic panel 3 is a flexible photovoltaic panel 3, in the second embodiment, the iron tower 1 is spaced apart in its axial direction with two brackets 2 corresponding to the photovoltaic panel group, and the plurality of drivers 5 in the driver group are divided into a plurality of upper drivers 52 and a plurality of lower drivers 53. Every two upper drivers 52 and lower drivers 53 are arranged opposite to each other and are respectively arranged on the upper bracket 2 and the lower bracket 2. The rotating shaft 54 ​​of the upper driver 52 is wound around the photovoltaic panel 3, and the rotating shaft 54 ​​of the lower driver 53 is connected to the photovoltaic panel 3 through a traction rope 8.

[0052] Specifically, each photovoltaic panel group corresponds to two brackets 2, and the two brackets 2 are spaced apart and sleeved on the iron tower 1. The bracket 2 is preferably a circular ring-shaped platform to better support the photovoltaic panels 3 arranged circumferentially around the iron tower 1. The multiple drivers 5 in the driver group all use rotary motors and are divided into multiple upper drivers 52 and multiple lower drivers 53. Every two upper drivers 52 and lower drivers 53 are correspondingly arranged and fixed on the upper bracket 2 and the lower bracket 2, respectively. The rotating shaft 54 ​​of the upper driver 52 is wound around the photovoltaic panel 3, and the part of the photovoltaic panel 3 extending out of the rotating shaft 54 ​​of the upper driver 52 is connected to the traction rope 8 wound around the rotating shaft 54 ​​of the lower driver 53. In this way, when the photovoltaic panel group needs to be opened, the rotating shaft 54 ​​of each lower driver 53 rotates to retract the traction rope 8, and the traction rope 8 drives the photovoltaic panel 3 to unfold downward, so that the photovoltaic power generation device is in a normal working state; when the photovoltaic panel group needs to be closed, the rotating shaft 54 ​​of each upper driver 52 rotates to retract the photovoltaic panel 3, and the photovoltaic panel 3 moves upward and wraps around the rotating shaft 54 ​​of the upper driver 52, so that the photovoltaic power generation device is in a windproof state. It should be noted that in the process of retracting the photovoltaic panel 3 upward, the traction rope 8 restrains the photovoltaic panel 3 to be completely retracted to ensure that the photovoltaic panel 3 can be unfolded later.

[0053] Based on the second embodiment, please refer to Figure 3 The rotating shafts 54 of the upper driver 52 and the lower driver 53 are both arranged horizontally, and the rotating shafts 54 of the upper driver 52 and the lower driver 53 are parallel to each other, so as to ensure that the photovoltaic panel 3 remains flat when unfolded, thereby ensuring that the photovoltaic panel 3 has good power generation efficiency and service life. In addition, the maximum distance between the rotating shaft 54 ​​of the lower driver 53 and the iron tower 1 is greater than the maximum distance between the rotating shaft 54 ​​of the upper driver 52 and the iron tower 1, so as to ensure that the photovoltaic panel 3 is tilted outward from top to bottom at a certain angle when unfolded, thereby improving the conversion efficiency of solar energy.

[0054] Based on the second embodiment, please refer to Figure 3 , each photovoltaic panel 3 in the photovoltaic panel group is located in the space formed between the two brackets 2.

[0055] It can be understood that since the two brackets 2 are arranged at intervals along the axial direction of the tower 1, there is a certain space between the two brackets 2. Each photovoltaic panel 3 in the photovoltaic panel group is arranged in this space, which can fully utilize the vertical space of the tower 1 and reduce the occupied space.

[0056] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0057] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0058] The above is a detailed introduction to a tower photovoltaic power generation device provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
