Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation technology, and in particular to a diesel generator device based on photovoltaic power generation. Background Technology

[0002] Photovoltaic power generation is a technology that directly converts solar energy into electrical energy through the photovoltaic effect. A photovoltaic power generation system typically consists of solar panels, inverters, mounting brackets, energy storage devices, and a power distribution control system. It can operate independently or be connected to the power grid and is a clean and renewable energy utilization method. A diesel generator is a small power generation device that uses diesel fuel and a diesel engine as the prime mover to drive a generator to produce electricity. A complete unit generally consists of a diesel engine, generator, control box, fuel tank, starting and control batteries, protection devices, emergency cabinet, and other components. A diesel generator is a combination of a diesel engine and a generator (usually an AC generator) to produce electrical energy.

[0003] Photovoltaic-based diesel generator sets combine the flexibility of renewable energy with the reliability of traditional power generation. They are mainly used for temporary power supply in emergency disaster relief. By generating electricity and storing energy during the day through photovoltaics, and generating electricity at night or on cloudy days through diesel engines, a 24-hour power supply is guaranteed.

[0004] In existing technologies, solar panels need to be assembled, installed, and fixed one by one after being transported to the site. This process is time-consuming and labor-intensive, and is particularly inefficient in scenarios requiring rapid deployment. It is not suitable for temporary power supply needs.

[0005] Therefore, it is necessary to provide a diesel generator device based on photovoltaic power generation to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide a diesel generator device based on photovoltaic power generation, so as to solve the defects and other problems of the prior art mentioned in the background art.

[0007] Based on the above ideas, the present invention provides the following technical solution: It includes a base, the top of which is provided with an angle-adjustable mounting bracket. The top of the mounting bracket is fully open. Inside the mounting bracket are a first photovoltaic panel, a second photovoltaic panel, and a third photovoltaic panel, stacked from top to bottom. The first photovoltaic panel is fixedly connected to the inside of the mounting bracket. The second and third photovoltaic panels are slidably connected to the mounting bracket via two sets of first sliding grooves, which are located on both sides of the inside of the mounting bracket. It also includes two sets of driving components, respectively used to drive the second and third photovoltaic panels to unfold in opposite directions. Each driving component includes components fixedly mounted on the mounting bracket. An electric push rod is located at the bottom of the internal structure. The output end of the electric push rod is fixedly connected to a fixed block. A connecting bracket is provided on one side of the fixed block. Two connecting brackets are respectively fixed to one end of the second photovoltaic panel and the third photovoltaic panel. The first sliding groove is smoothly connected by a set of first straight grooves and a set of first arc-shaped grooves. Second sliders are fixedly connected to both sides of the end of the second and third photovoltaic panels away from the connecting brackets. One end of the second slider is located inside the first sliding groove and slides within it. The fixed block and connecting brackets are slidably connected. A pulley is rotatably connected to the side of the connecting bracket away from the fixed block. A protrusion is movably connected to the bottom of the pulley. A transmission component is provided on the side of the protrusion near the fixed block, used to drive the protrusion to rotate 110 degrees, lifting the pulley upwards.

[0008] As a further aspect of the present invention: the transmission assembly includes a rotating rod, which passes through and is rotatably connected to the fixed block, one end of the rotating rod is coaxially fixed to the protrusion, a sleeve is sleeved on the outside of the rotating rod, and the sleeve passes through and is fixed to the mounting bracket; a first slider is fixedly connected to the outside of one end of the rotating rod, one end of the first slider is disposed in a second sliding groove and slides therewith, and the second sliding groove is opened inside the sleeve.

[0009] As a further aspect of the present invention: the second groove is smoothly connected by a set of second straight grooves and a set of second arc-shaped grooves.

[0010] As a further aspect of the present invention: a groove is provided at the end of the rotating rod away from the protrusion, and a linkage component is provided inside the groove for adjusting the angle of the mounting bracket.

[0011] As a further aspect of the present invention: the linkage component includes a telescopic rod, one end of which is fixedly connected to the inner wall of the rotating rod, and the other end of which is fixedly connected to a round rod. The outer side of the round rod is connected to a rotating shaft via a gear set. Both ends of the rotating shaft pass through and are fixed to the mounting bracket, and the rotating shaft passes through and is rotatably connected to the base.

[0012] As a further aspect of the present invention: the gear set includes a first gear and a second gear, the first gear and the second gear being meshed together, the first gear and the second gear being fixedly connected to the outside of the round rod and the rotating shaft respectively; the number of teeth of the first gear is less than the number of teeth of the second gear.

[0013] As a further aspect of the present invention: the rotating shaft is positioned near one end of the mounting bracket, and a support block is provided at the bottom of the end of the mounting bracket furthest from the rotating shaft.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: by stacking the first, second, and third photovoltaic power generation panels, transportation is not only facilitated, but also, in conjunction with the drive components, the stacked photovoltaic panels can be quickly deployed to carry out temporary power supply operations, improving both work efficiency and power generation efficiency. Through the arrangement of protrusions and pulleys, combined with the cooperation of the drive and transmission components, the second and third photovoltaic power generation panels are raised to the same height as the first photovoltaic power generation panel, preventing local shading between the photovoltaic panels and further improving power generation efficiency. Furthermore, through the cooperation of the drive, transmission, and linkage components, the first, second, and third photovoltaic power generation panels simultaneously form a 20-degree tilt angle, allowing them to face the sunlight directly, further improving power generation efficiency.

[0015] Compared with the prior art, the beneficial effect of the present invention is that the power generation device is equipped with a wind speed sensor. When the wind speed is high, the first photovoltaic power generation panel, the second photovoltaic power generation panel, and the third photovoltaic power generation panel located at the same height can switch their forms to a stacked state. At the same time, the tilt angle of the first photovoltaic power generation panel, the second photovoltaic power generation panel, and the third photovoltaic power generation panel becomes 0 degrees, which can reduce the damage of strong winds to the photovoltaic panels.

[0029] Example 1, as Figures 1 to 4 As shown, a diesel generator device based on photovoltaic power generation includes a base. The bottom of the base is equipped with two directional wheels and two omnidirectional wheels. All four wheels have a self-locking function, which is existing technology and will not be described in detail here. This facilitates the movement of the power supply equipment during temporary power supply. The base also carries a diesel generator device for power supply at night or on cloudy days. In addition, the base carries a battery for storing electrical energy. All of these are existing technologies and will not be described in detail here.

[0030] The photovoltaic power generation system in this application is connected to the grid and the diesel generator set for power supply at the same time. The output is coordinated by the inverter and the synchronous controller. When there is sufficient sunlight, the photovoltaic power generation system outputs the maximum power through the inverter to meet the power supply demand. The remaining electricity is stored through the energy storage system. In this state, the diesel generator set is in the off state.

[0031] In cases of insufficient sunlight or a sudden surge in power demand, the central controller can monitor load demand in real time. The controller dynamically adjusts the power supply ratio based on load demand and energy priority (photovoltaic power generation system is greater than energy storage system, and energy storage system is greater than diesel generator system). Specifically, if the output power of the photovoltaic system is insufficient while the energy storage system has sufficient energy, the energy storage system's batteries will be used first for power supply. If the battery capacity is insufficient, the diesel generator system will be started. Through a static switching switch, seamless switching can be performed between the photovoltaic power generation system and the diesel generator system, and the diesel generator system will be automatically started to supplement the power supply. The hybrid photovoltaic and diesel generator system can achieve efficient collaboration, combining environmental protection and reliability, and is particularly suitable for scenarios where renewable energy is unstable but high power quality is required.

[0032] A synchronization device can also be installed to ensure that the phase, frequency, and amplitude of the photovoltaic inverter and the diesel engine output voltage are synchronized.

[0033] The base has an adjustable mounting bracket 1 at its top, which is fully open at the top. Inside the mounting bracket 1 are a first photovoltaic panel 2, a second photovoltaic panel 3, and a third photovoltaic panel 4, stacked from top to bottom. The first photovoltaic panel 2 is fixedly connected to the inside of the mounting bracket 1. The second photovoltaic panel 3 and the third photovoltaic panel 4 are slidably connected to the mounting bracket 1 through two sets of first sliding grooves 101, which are located on both sides inside the mounting bracket 1. The base also includes two sets of drive components 5, which are used to drive the second photovoltaic panel 3 and the third photovoltaic panel 4 to unfold in opposite directions. The drive components 5 include an electric push rod 501 fixedly installed at the bottom inside the mounting bracket 1. The output end of the electric push rod 501 is fixedly connected to a fixing block 502. A connecting bracket 503 is provided on one side of the fixing block 502. The two connecting brackets 503 are fixed to one end of the second photovoltaic panel 3 and the third photovoltaic panel 4, respectively.

[0034] In this embodiment, during transportation, all four wheels at the bottom are in a self-locking state, and the state of the power generation device during transportation (e.g.) Figure 1 As shown), the first photovoltaic panel 2, the second photovoltaic panel 3, and the third photovoltaic panel 4 are stacked in layers, reducing the floor space required and facilitating transportation. Upon arrival at the usage location, two sets of electric push rods 501 are simultaneously activated to drive two sets of fixing blocks 502 to move horizontally in opposite directions. The connecting bracket 503 moves synchronously with the fixing blocks 502, and the second photovoltaic panel 3 and the third photovoltaic panel 4 move horizontally in opposite directions along with the two sets of connecting brackets 503, allowing the second photovoltaic panel 3 and the third photovoltaic panel 4 to quickly unfold (as shown). Figure 2As shown, to improve power generation efficiency, the two sets of electric push rods 501 are both set at the bottom of the third photovoltaic panel 4 to avoid shading the first photovoltaic panel 2, the second photovoltaic panel 3, and the third photovoltaic panel 4, thereby reducing power generation efficiency.

[0035] like Figures 3 to 4 As shown, as a further embodiment of the present invention, the first slide groove 101 is smoothly connected by a set of first straight grooves and a set of first arc grooves; the second photovoltaic power generation panel 3 and the third photovoltaic power generation panel 4 are fixedly connected to both sides of the end away from the connecting bracket 503 with a second slider 10, one end of the second slider 10 is disposed inside the first slide groove 101 and slides therewith.

[0036] In this embodiment, the second slider 10 is a horizontally placed cylinder. One end of the cylinder is located inside the first groove 101 and slides therewith. The structural design of the cylinder can ensure that it can slide smoothly in the first arc groove without jamming.

[0037] like Figures 4 to 6 As shown, as a further embodiment of the present invention, the fixing block 502 and the connecting bracket 503 are slidably connected; the connecting bracket 503 is rotatably connected to the pulley 7 on the side away from the fixing block 502, and the bottom of the pulley 7 is movably connected to the protrusion 6, which is designed in a similar triangular shape; a transmission component 8 is provided on the side of the protrusion 6 near the fixing block 502.

[0038] In this embodiment, as the second photovoltaic panel 3 and the third photovoltaic panel 4 unfold horizontally in opposite directions, the second slider 10 slides from one end of the first straight groove to the smooth connection between the first arc-shaped groove and the first straight groove. During this process, the protrusion 6 and the pulley 7 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. Meanwhile, the second slider 10 moves from the smooth connection between the first arc-shaped groove and the first straight groove to the tail end of the first arc-shaped groove. During this movement, one end of the second photovoltaic panel 3 and the third photovoltaic panel 4 slowly rises upwards while moving horizontally. Simultaneously, the transmission assembly... 8 drives the protrusion 6 to rotate 110 degrees, lifting the pulley 7 movably connected to it upwards. The connecting bracket 503 then moves synchronously with the pulley 7. Simultaneously, the two sets of connecting brackets 503 are fixedly connected to the ends of the second photovoltaic panel 3 and the third photovoltaic panel 4 furthest from the second slider 10, respectively. Therefore, when the connecting bracket 503 is lifted upwards, it can drive the ends of the second photovoltaic panel 3 and the third photovoltaic panel 4 furthest from the second slider 10 to rise upwards, thus enabling both ends of the second photovoltaic panel 3 and the third photovoltaic panel 4 to move upwards synchronously until the first photovoltaic panel 2, the second photovoltaic panel 3, and the third photovoltaic panel 4 are raised to the same horizontal line (e.g., ...). Figure 5 , Figure 6As shown in the figure, maintain a high degree of consistency to prevent local shading between photovoltaic panels.

[0039] like Figures 8 to 11 As shown, as a further embodiment of the present invention, the transmission assembly 8 includes a rotating rod 801, which passes through and is rotatably connected to the fixing block 502. One end of the rotating rod 801 is coaxially fixed to the protrusion 6. A sleeve 802 is sleeved on the outside of the rotating rod 801, which passes through and is fixed to the mounting bracket 1. 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 disposed in the second sliding groove 804 and slides therewith. The second sliding groove 804 is opened inside the sleeve 802 and is smoothly connected by a set of second straight grooves and a set of second arc-shaped grooves.

[0040] 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 follows the first slider 803 and moves horizontally. When the second slider 10 moves from the smooth connection between the first arc groove and the first straight groove to the tail end of the first arc groove, the first slider 803 slides inside the second arc groove. At this time, the first slider 803 rotates by an angle of 110 degrees. The rotating rod 801 rotates with the first slider 803, and the protrusion 6 rotates with the rotating rod 801, thereby lifting the photovoltaic panel.

[0041] like Figure 9 As shown, as a further embodiment of the present invention, a groove is provided at the end of the rotating rod 801 away from the protrusion 6, and a linkage component 9 is provided inside the groove for adjusting the angle of the mounting bracket 1.

[0042] like Figure 9 As shown, as a further embodiment of the present invention, the linkage component 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 to a round rod 902. The round rod 902 passes through the mounting bracket 1 and is rotatably connected to it. The outer side of the round rod 902 is connected to a rotating shaft 905 through a gear set. Both ends of the rotating shaft 905 pass through the mounting bracket 1 and are fixed to it. The rotating shaft 905 also passes through the base and is rotatably connected to it.

[0043] In this embodiment, when the rotating rod 801 moves linearly, the telescopic rod 901 extends and retracts, while the round rod 902 remains stationary. When the rotating rod 801 moves linearly while rotating, the round rod 902 rotates, driving the rotating shaft 905 to rotate via the gear set. The rotation of the rotating shaft 905 then drives the mounting bracket 1 to rotate by a fixed angle (e.g., ...). Figure 7 As shown in the figure, the first photovoltaic panel 2, the second photovoltaic panel 3, and the third photovoltaic panel 4 can all face the sunlight, thus improving power generation efficiency.

[0044] like Figure 9 As shown, as a further embodiment of the present invention, the gear set includes a first gear 903 and a second gear 904, the first gear 903 and the second gear 904 are meshed and connected, and the first gear 903 and the second gear 904 are respectively fixedly connected to the outside of the round rod 902 and the rotating shaft 905.

[0045] In this embodiment, the number of teeth of the first gear 903 is less than the number of teeth of the second gear 904. Therefore, the first gear 903 rotates 110 degrees, while the second gear 904 only rotates 20 degrees. By setting the difference in rotation speed, it is ensured that the protrusion 6 can not only lift the pulley 7, but also ensure the preset angle of the photovoltaic panel, thereby improving the power generation efficiency.

[0046] like Figure 4 As shown, as a further embodiment of the present invention, the rotating shaft 905 is positioned close to one end of the mounting bracket 1, and a support block 11 is provided at the bottom of the end of the mounting bracket 1 away from the rotating shaft 905.

[0047] In this embodiment, the support block 11 is placed on the relatively heavy side of the bottom of the mounting bracket 1 to support the mounting bracket 1, thereby improving the stability of the mounting bracket 1.

[0048] In this invention, a wind speed sensor, model Gill WindSonic4, is installed on the base. Once a high wind speed is detected, an electrical signal is sent to the electric push rod 501. The two sets of electric push rods 501 can drive the second photovoltaic panel 3 and the third photovoltaic panel 4 to reset, changing from an unfolded state to a stacked state. At the same time, the tilt angle of the first photovoltaic panel 2, the second photovoltaic panel 3, and the third photovoltaic panel 4 becomes 0 degrees, which can prevent damage to the photovoltaic panels from strong winds.

[0049] 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 to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
