[0032] Example 1, as Figures 1 to 4 shown, a diesel generator device based on photovoltaic power generation includes a base. Two directional wheels and two universal wheels are installed at the bottom of the base. At the same time, all four wheels have a self-locking function. This is prior art and will not be elaborated here. It is convenient to move the power supply equipment during temporary power supply. At the same time, a diesel generator device is mounted on the base for power supply at night or on cloudy days, and a storage battery is mounted on the base for storing electric energy. These are all prior art and will not be elaborated here.

[0033] In the photovoltaic power generation system of this application, it is connected to the grid for power supply simultaneously with the diesel generator set. Through the coordination of the inverter and the synchronous controller for output. When there is sufficient sunlight, the photovoltaic power generation system outputs the maximum power through the inverter to meet the power supply demand, and the remaining power is stored through the energy storage system. In this state, the diesel generator set is in a shutdown state;

[0034] In the case of insufficient sunlight or a sudden increase in power supply demand, the central controller can be used to monitor the load demand in real time. The controller dynamically adjusts the power supply ratio according to the load demand and the energy priority (photovoltaic power generation system > energy storage system power supply, and energy storage system power supply > diesel engine power generation system). The specific operation is as follows: if the output power of the photovoltaic system is insufficient and the energy storage of the energy storage system is sufficient, the battery of the energy storage system is preferentially used for power supply. After the battery capacity is insufficient, the diesel engine system is started. Through the static transfer switch, seamless switching is carried out between the photovoltaic power generation system and the diesel generator set power generation system, and the diesel engine system is automatically started to supplement the power supply. The photovoltaic power generation and diesel power generation hybrid system can achieve efficient coordination, combining environmental protection and reliability, and is particularly suitable for scenarios where renewable energy is unstable but high power supply quality is required.

[0035] Meanwhile, a synchronization device can be installed to ensure the synchronization of the phase, frequency, and amplitude of the output voltages of the photovoltaic inverter and the diesel engine.

[0036] An installation bracket 1 with adjustable angle is provided at the top of the base. The top of the installation bracket 1 is in a fully open state. Inside the installation bracket 1, there are a first photovoltaic panel 2, a second photovoltaic panel 3, and a third photovoltaic panel 4. The first photovoltaic panel 2, the second photovoltaic panel 3, and the third photovoltaic panel 4 are stacked and distributed from top to bottom. The first photovoltaic panel 2 is fixedly connected to the inside of the installation bracket 1. The second photovoltaic panel 3 and the third photovoltaic panel 4 are both slidably connected to the installation bracket 1 through two groups of first chutes 101. The first chutes 101 are opened on both sides inside the installation bracket 1; there are also two groups of driving components 5, which are respectively used to drive the second photovoltaic panel 3 and the third photovoltaic panel 4 to unfold in opposite directions. The driving component 5 includes an electric push rod 501 fixedly installed at the bottom end inside the installation bracket 1. The output end of the electric push rod 501 is fixedly connected with a fixed block 502. One side of the fixed block 502 is provided with a connecting bracket 503. The two connecting brackets 503 are respectively fixed to one end of the second photovoltaic panel 3 and the third photovoltaic panel 4.

[0037] In this embodiment, during transportation, the four wheels at the bottom are in a self-locking state, and the state of the power generation device during transportation (such as Figure 1As shown in the figure, the first photovoltaic power generation panel 2, the second photovoltaic power generation panel 3, and the third photovoltaic power generation panel 4 are stacked on top of each other, reducing the floor area and facilitating transportation. When they reach the usage location, two sets of electric push rods 501 can be simultaneously activated to drive two sets of fixed blocks 502 to move horizontally in opposite directions. The connecting brackets 503 will move synchronously with the fixed blocks 502, and the second photovoltaic power generation panel 3 and the third photovoltaic power generation panel 4 will move horizontally in opposite directions along with the two sets of connecting brackets 503, enabling the second photovoltaic power generation panel 3 and the third photovoltaic power generation panel 4 to be quickly unfolded (as Figure 2 shown). To improve the power generation efficiency, the two sets of electric push rods 501 here are both arranged at the bottom of the third photovoltaic power generation panel 4 to avoid blocking the first photovoltaic power generation panel 2, the second photovoltaic power generation panel 3, and the third photovoltaic power generation panel 4, thereby reducing the power generation efficiency.

[0038] As Figures 3 to 4 shown, as a further solution of the present invention, the first sliding groove 101 is smoothly connected by a set of first straight grooves and a set of first arc grooves; both sides of the ends of the second photovoltaic power generation panel 3 and the third photovoltaic power generation panel 4 far from the connecting bracket 503 are fixedly connected with second sliders 10, and one end of the second slider 10 is arranged inside the first sliding groove 101 and is slidably matched with it.

[0039] In this embodiment, the shape of the second slider 10 is a horizontally placed cylinder, and one end of the cylinder is arranged inside the first sliding groove 101 and slides with it. The structural design of the cylinder can ensure smooth sliding in the first arc groove without jamming.

[0040] As Figures 4 to 6 shown, as a further solution of the present invention, the fixed block 502 and the connecting bracket 503 are slidably connected; a pulley 7 is rotatably connected to the side of the connecting bracket 503 far from the fixed block 502, a convex block 6 is movably connected to the bottom of the pulley 7, and the convex block 6 is designed in a shape similar to a triangle; a transmission component 8 is arranged on the side of the convex block 6 close to the fixed block 502.

[0041] In this embodiment, during the process of the second photovoltaic panel 3 and the third photovoltaic panel 4 horizontally unfolding in opposite directions, the second slider 10 slides from one end of the first straight groove to the smooth connection between the first arc groove and the first straight groove. During this process, the positions of the convex block 6 and the pulley 7 always remain relatively stationary. At this time, the electric push rod 501 continues to drive the second photovoltaic panel 3 and the third photovoltaic panel 4 to move horizontally. At this time, the second slider 10 moves from the smooth connection between the first arc groove and the first straight groove to the end of the first arc groove. During this movement process, one end of the second photovoltaic panel 3 and the third photovoltaic panel 4 slowly rises upward while moving horizontally. At the same time, the transmission component 8 drives the convex block 6 to rotate 110 degrees, lifting the pulley 7 movably connected thereto upward. The connecting bracket 503 then moves synchronously with the pulley 7. At the same time, the two groups of connecting brackets 503 are respectively fixedly connected to one end of the second photovoltaic panel 3 and the third photovoltaic panel 4 away from the second slider 10. Therefore, when the connecting bracket 503 rises upward, it can drive one end of the second photovoltaic panel 3 and the third photovoltaic panel 4 away from the second slider 10 to rise upward, so that both ends of the second photovoltaic panel 3 and the third photovoltaic panel 4 can move upward synchronously until the first photovoltaic panel 2, the second photovoltaic panel 3, and the third photovoltaic panel 4 are lifted to the same horizontal line (as Figure 5 , Figure 6 shown), to keep the height consistent and prevent local shading between the photovoltaic panels.

[0042] As Figures 8 to 11 shown, as a further solution of the present invention, the transmission component 8 includes a rotating rod 801. The rotating rod 801 passes through the fixed block 502 and is rotatably connected thereto. One end of the rotating rod 801 is coaxially fixed to the convex block 6. A sleeve 802 is sleeved outside the rotating rod 801. The sleeve 802 passes through the mounting bracket 1 and is fixed thereto; a first slider 803 is fixedly connected to the outside of one end of the rotating rod 801. One end of the first slider 803 is arranged in the second chute 804 and is slidably matched therewith. The second chute 804 is opened inside the sleeve 802. The second chute 804 is smoothly connected by a group of second straight grooves and a group of second arc grooves.

[0043] In this embodiment, the second slider 10 slides from one end of the first straight groove to the smooth connection between the first arc groove and the first straight groove. The first slider 803 slides inside the second straight groove. At this time, the rotating rod 801 moves horizontally following the first slider 803. When the second slider 10 moves from the smooth connection between the first arc groove and the first straight groove to the end of the first arc groove, at this time, the first slider 803 slides inside the second arc groove. At this time, the first slider 803 rotates, and the rotation angle is 110 degrees. The rotating rod 801 rotates following the first slider 803, and the convex block 6 rotates following the rotating rod 801, thereby lifting the photovoltaic panel.

[0044] As Figure 9As shown in the figure, as a further solution of the present invention, a groove is provided at one end of the rotating rod 801 away from the convex block 6, and a linkage assembly 9 is arranged inside the groove for adjusting the angle of the mounting bracket 1.

[0045] As Figure 9 shown in the figure, as a further solution of the present invention, the linkage assembly 9 includes a telescopic rod 901. One end of the telescopic rod 901 is fixedly connected to the inner wall of the rotating rod 801, and the other end of the telescopic rod 901 is fixedly connected with a round rod 902. The round rod 902 penetrates through the mounting bracket 1 and is rotatably connected thereto. The outer side of the round rod 902 is connected with a rotating shaft 905 through a gear set. Both ends of the rotating shaft 905 penetrate through the mounting bracket 1 and are fixedly connected thereto, and the rotating shaft 905 penetrates through the base and is rotatably connected thereto.

[0046] In this embodiment, when the rotating rod 801 makes a linear motion, the telescopic rod 901 expands and contracts. At this time, the position of the round rod 902 remains unchanged. When the rotating rod 801 makes a linear motion and rotates at the same time, at this time the round rod 902 rotates, and drives the rotating shaft 905 to rotate through the transmission of the gear set. The rotation of the rotating shaft 905 drives the mounting bracket 1 to rotate a fixed angle (as Figure 7 shown in the figure), so that the first photovoltaic panel 2, the second photovoltaic panel 3, and the third photovoltaic panel 4 can all face the sun directly, improving the power generation efficiency.

[0047] As Figure 9 shown in the figure, as a further solution of the present invention, the gear set includes a first gear 903 and a second gear 904. The first gear 903 is meshed and connected with the second gear 904. The first gear 903 and the second gear 904 are respectively fixedly connected to the outer sides of the round rod 902 and the rotating shaft 905.

[0048] In this embodiment, the number of teeth of the first gear 903 is less than that of the second gear 904. Therefore, when the first gear 903 rotates 110 degrees, the second gear 904 only rotates 20 degrees. Through the setting of the speed difference, it is ensured that the convex block 6 can not only complete the lifting of the pulley 7, but also ensure the preset angle of the photovoltaic panel, improving the power generation efficiency.

[0049] As Figure 4 shown in the figure, as a further solution of the present invention, the rotating shaft 905 is arranged near one end of the mounting bracket 1, and a support block 11 is arranged at the bottom of the end of the mounting bracket 1 away from the rotating shaft 905.

[0050] In this embodiment, the support block 11 is arranged on the relatively heavier side at the bottom of the mounting bracket 1 for supporting the mounting bracket 1, thereby improving the stability of the mounting bracket 1.

[0051] In the present invention, a wind speed sensor, model Gill WindSonic4, is installed on the base. Once a large wind speed is detected, an electrical signal can be sent to the electric push rods 501. The two groups of electric push rods 501 can drive the second photovoltaic panel 3 and the third photovoltaic panel 4 to reset, changing from the unfolded state to the stacked state. At the same time, the tilt angles of the first photovoltaic panel 2, the second photovoltaic panel 3, and the third photovoltaic panel 4 become 0 degrees, which can prevent damage to the photovoltaic panels caused by strong winds.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only used to illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and all these changes and improvements fall within the scope of the present invention claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
