[0027] In order to make the purpose, technical solution and beneficial effects of the utility model more clear, the technical solution of the utility model is further described below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0028] In the embodiment of the present utility model, Figure 1-Figure 3 As shown, the installation structure of the photovoltaic panel 3 includes: a cabinet 1, a wind direction axis 2 and a light-chasing component; the wind direction axis 2 is rotatably arranged on the cabinet 1 along an axis extending in the up-down direction; the light-chasing component is arranged on the wind direction axis 2, and the light-chasing component links the photovoltaic panel 3 to rotate forward and reverse along an axis extending in the left-right direction, and enables the photovoltaic panel 3 to have a first pitch state and a second pitch state, and when switching between the first pitch state and the second pitch state, the inclination angle of the photovoltaic panel 3 is adjusted.

[0029] Specifically, in the embodiment of the utility model, the photovoltaic panel 3 can use the clean energy of sunlight as power generation compensation during the day to reduce the power grid load of the highway. At the same time, the excess electric energy can be stored in the energy storage system to serve as backup power for the cabinet 1 system; an energy storage battery can be arranged in the cabinet 1 to store excess electric energy to serve as backup power for electronic equipment at night or when the power grid is out of power.

[0030] In an embodiment of the utility model, a wind direction axis 2 is provided on the upper surface of the cabinet 1. The wind direction axis 2 is vertically arranged and can rotate along an axial direction extending in the up and down directions, so as to link the photovoltaic panel 3 to rotate on a horizontal plane, so that the side of the photovoltaic panel 3 is parallel to the wind direction, thereby reducing the windward area of ​​the photovoltaic panel 3 and reducing the damage to the photovoltaic panel 3 caused by strong winds.

[0031] In the embodiment of the utility model, the photovoltaic panel 3 is connected to the wind direction axis 2 via a light-chasing component. On the one hand, the photovoltaic panel 3 can rotate with the wind direction axis 2. On the other hand, due to the rotational connection between the light-chasing component and the photovoltaic panel 3, the photovoltaic panel 3 can be reversed along the axis extending in the left and right directions, so that the photovoltaic panel 3 forms a first pitch state and a second pitch state. Driven by an external force, the photovoltaic panel 3 can switch between the first pitch state and the second pitch state to adjust the inclination angle of the photovoltaic panel 3, complete the alignment of the optimal solar radiation surface, and optimize the power generation capacity of the photovoltaic panel 3.

[0032] The utility model links the photovoltaic panel 3 to rotate through the wind direction axis 2 so that its side is parallel to the wind direction, thereby reducing wind resistance; and while changing the rotation angle of the photovoltaic panel 3, the chasing light component can independently (or one in front and one behind) drive the photovoltaic panel 3 to continuously tilt, so as to change the position angle of the photovoltaic panel 3 in the horizontal direction and the vertical direction, complete the wind direction position adjustment of the photovoltaic panel 3 and re-adjust the chasing light, thereby adjusting the windward area of ​​the photovoltaic panel 3, reducing the damage to the photovoltaic panel 3 caused by strong winds, and compensating for power generation to achieve the optimal power generation capacity.

[0033] like Figure 2 , Figure 3 As shown, in one embodiment, the light-chasing assembly includes a light-chasing shaft 4 and a telescopic connecting rod 5 that are rotatably connected. The light-chasing shaft 4 is arranged on the wind direction shaft 2 along the front-back direction, and its front end is rotatably connected to the photovoltaic panel 3. The end of the telescopic connecting rod 5 that is away from the light-chasing shaft 4 is rotatably connected to the photovoltaic panel 3, so that a first support position is formed between the light-chasing shaft 4, the telescopic connecting rod 5 and the photovoltaic panel 3. Specifically, in order to limit the rotation of the photovoltaic panel 3 within a certain tilt angle, the light-chasing shaft 4 and the telescopic connecting rod 5 are rotatably connected to the back of the photovoltaic panel 3 by the rotatably connected light-chasing shaft 4 and the telescopic connecting rod 5, respectively, so that the axis of the photovoltaic panel 3 extending along the left and right directions is reversed under the drive of the (electric) telescopic connecting rod, thereby realizing the light-chasing adjustment of the photovoltaic panel 3 and compensating for power generation. On the other hand, the light-chasing shaft 4 is arranged along the front-back direction, and forms a stable first support position between the photovoltaic panel 3 and the telescopic connecting rod 5. The first support position is a nearly triangular structure to improve the overall strength of the light-chasing assembly.

[0034] Further, if Figure 2 , Figure 3As shown, in one embodiment, the front end of the light-chasing axis 4 extends a first support rod 6 and a second support rod 7 in different directions, and the photovoltaic panel 3 is hinged to the first support rod 6 and the second support rod 7, respectively, so that a second support position is formed between the first support rod 6, the second support rod 7 and the photovoltaic panel 3. Specifically, in order to further improve the structural strength of the light-chasing assembly, the present embodiment arranges the first support rod 6 and the second support rod 7 at the front end of the light-chasing axis 4, one end of the first support rod 6 and the second support rod 7 can be detachably fixed to the front end of the light-chasing axis 4, and the other ends of both are hinged to the photovoltaic panel 3; since the first support rod 6 and the second support rod 7 extend in different directions, a second support position can be formed between the first support rod 6, the second support rod 7 and the photovoltaic panel 3; similarly, the second support position is a triangular structure, and the use of a double-point connection method can improve the structural strength of the light-chasing assembly to ensure that the photovoltaic panel 3 can rotate normally.

[0035] Preferably, Figure 3 As shown, the angle between the first support rod 6 and the second support rod 7 is defined as α, and α satisfies 0°<α<180°; so that the second support position always forms a triangular structure with the photovoltaic panel 3, and the structure is more stable.

[0036] Preferably, Figure 1 , Figure 2 As shown, the photovoltaic panel 3 is formed with a first hinge point 8 and two second hinge points 9, the telescopic link 5 is located at the first hinge point 8, and the first support rod 6 and the second support rod 7 are respectively located at the two second hinge points. The first hinge point 8 and the second hinge point are both formed with connecting ears for being hinged to the corresponding telescopic link 5, the first support rod 6 or the second support rod 7 respectively.

[0037] like Figure 3 As shown, in one embodiment, a protrusion extends upward from the end of the wind direction shaft 2, and the light-chasing shaft 4 is formed with a mounting hole 10 for avoiding the protrusion. Specifically, in order to enable the wind direction shaft 2 to rotate in conjunction with the photovoltaic panel 3 through the light-chasing shaft 4, this embodiment provides a protrusion at the upper end of the wind direction shaft 2 and a mounting hole 10 at the middle of the light-chasing shaft 4. The mounting hole 10 cooperates with the protrusion to avoid the protrusion, so as to achieve rapid connection and synchronous rotation of the wind direction shaft 2 and the light-chasing shaft 4.

[0038] In one embodiment, the wind direction shaft 2 is driven by a gear rack mechanism; to improve the rotation stability of the wind direction shaft 2, the gear rack mechanism (not shown) is driven by a wind direction motor placed in the cabinet 1, and the wind direction motor is powered by a photovoltaic panel 3.

[0039] like Figure 1As shown, in one embodiment, a plurality of partitions 11 are arranged at intervals in the cabinet 1. Specifically, in order to arrange the electronic equipment or energy storage batteries in the cabinet 1 neatly, the partitions 11 are arranged in the cabinet 1, and the partitions 11 can improve the space utilization rate of the internal space of the cabinet 1; on the other hand, a card slot is arranged inside the cabinet 1 for fixing the partitions 11 at any height to adapt to the installation requirements of different electronic equipment.

[0040] The present embodiment further provides a photovoltaic system, including the above-mentioned mounting structure and a wind direction sensor 12; the specific structure of the mounting structure refers to the above-mentioned embodiment. Since the present photovoltaic system adopts all the technical solutions of the above-mentioned embodiment, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiment, which will not be repeated here; the wind direction sensor 12 is arranged in the cabinet 1, and the wind direction sensor 12 is linked to the wind direction shaft 2 through a photovoltaic controller to control the rotation of the wind direction shaft 2 according to the wind direction.

[0041] Specifically, when the wind direction sensor 12 detects the direction of the wind, the photovoltaic controller determines the wind direction at this time according to the signal of the wind direction sensor 12, and controls the rotation of the wind direction motor by detecting the signal of the motor position sensor to complete the control of the wind direction axis 2, so that the side of the photovoltaic panel 3 is parallel to the wind direction, thereby reducing the windward area of ​​the photovoltaic system and reducing the damage to the photovoltaic system caused by strong winds; and the photoelectric sensor (not shown) is linked to the telescopic link 5 through the photovoltaic controller to control the telescopic link 5 to drive the photovoltaic panel 3 to rotate according to the light intensity, so as to adjust the inclination angle of the photovoltaic panel 3, and re-perform light chasing adjustment and compensation power generation.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
