Description

Technical Field

[0001] The present invention relates to a movable off-grid power generation, energy storage and power supply system. Background Art

[0002] With the rising energy prices, the development and utilization of new energy have become the main research topic in the current energy field. Due to the advantages of solar energy such as pollution-free, no geographical restrictions, and inexhaustible, the research on solar power generation has become the main direction for the development and utilization of new energy. Using solar cells to generate electricity is a main way for people to use solar energy today.

[0003] According to the needs of people's daily life and work, movable off-grid solar power supply systems are increasingly needed by people, such as the following situations:

[0004] 1. With the improvement of environmental awareness and the promotion of new energy vehicles by the government, more and more new energy vehicles have entered people's lives. Currently, the charging piles are not yet perfect and the charging conditions are not yet mature.

[0005] 2. Some people are restricted by their working areas and work in remote areas for a long time. Their living electricity is basically supplied by diesel / gasoline generators, and the noise generated by the generators affects the rest of the employees.

[0006] 3. There are many herdsmen in the vast and sparsely populated areas such as Tibet, Xinjiang, and Inner Mongolia. They have been living a migratory life for a long time, and the places where they live are not electrified. Food cannot be kept for a long time, which brings troubles to their lives.

[0007] 4. With the improvement of living standards, more and more people like to drive to remote areas for tourism and stay overnight in the wild. There is no power supply at night, which brings troubles to their lives.

[0008] 5. Some people in remote and powerless areas have also purchased solar photovoltaic products. The front panel of the existing photovoltaic products is made of glass material, resulting in a large weight and fragility of the entire photovoltaic product, which is not suitable for people who need to move frequently; the power generation of the photovoltaic product is small and not enough for a day's electricity consumption, and it is not enough to greatly improve the quality of life.

[0009] It can be seen that the existing movable off-grid solar power supply systems in the prior art still have many deficiencies in development, and a movable off-grid power generation, energy storage and power supply system is urgently needed to be developed. Summary of the Invention

[0010] To solve the above problems, the purpose of the present invention is to provide a movable off-grid power generation, energy storage and power supply system, which has a large power generation capacity and can provide energy for electric vehicles and also for daily life.

[0018] Further, the vehicle is provided with a switchable ramp door. When the ramp door is opened, one end of the ramp door is connected to the vehicle and the other end abuts against the ground, for the trolley device to be pushed into or pulled out of the vehicle along the ramp door.

[0019] Further, a number of balls for assisting the movement of the solar photovoltaic module thereon are provided on the bearing surface of the trolley body.

[0020] Further, a hoisting device or a stretching device for carrying the solar photovoltaic module / and the trolley device into the vehicle is provided on the vehicle.

[0070] The following elaborates on the preferred embodiments of the present invention in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art.

[0071] Refer to the attached Figure 1 to the attached Figure 25 In this embodiment, a movable off-grid power generation, energy storage and power supply system includes a vehicle 100, a power supply module (not shown in the drawings) and a control and inversion module (not shown in the drawings) disposed in the vehicle 100, a solar power supply device disposed in the vehicle 100 and removable, and a power output module. The solar power supply device includes a plurality of solar photovoltaic modules 200 that can be deployed and retracted. Each solar photovoltaic module 200 includes a plurality of independently power-supplying solar photovoltaic panels 210. Each adjacent two solar photovoltaic panels 210 are relatively movably connected through a connecting mechanism 220. When the solar photovoltaic module 200 is in the deployed state, each adjacent two solar photovoltaic panels 210 are unfolded from each other through the connecting mechanism 220. When the solar photovoltaic panel 210 module is in the retracted state, each adjacent two solar photovoltaic panels 210 are close to each other and retracted through the connecting mechanism 220. When the solar power supply device is in the working state, at least one solar photovoltaic module 200 is taken out of the vehicle 100 and connected to the control and inversion module through a cable 300, and the solar photovoltaic module 200 is in the deployed state. When the solar power supply device is in the standby state, all solar photovoltaic modules 200 are in the retracted state and placed in the vehicle 100.

[0072] When the solar power supply device is in the working state, the solar photovoltaic module 200 is deployed and laid flat on the ground. According to different terrains and spaces, the number and arrangement methods of the solar photovoltaic modules 200 can be selected according to the actual situation. As shown in the attached Figure 2 to the attached Figure 4 , multiple solar photovoltaic modules 200 can be placed in a row, or multiple solar photovoltaic modules can be placed side by side, or multiple solar photovoltaic modules can be placed in series and parallel.

[0073] Regarding the solar photovoltaic panel 210, conventional structures and materials can be adopted. As shown in the attached Figure 5As shown in the figure, it includes a front panel 211, an upper encapsulation material 212, a battery cell 213 layer, a lower encapsulation material 214, and a back panel 215 arranged in sequence from top to bottom. The front panel 211 is made of glass, and the back panel 215 is made of glass or polymer materials, etc. The solar photovoltaic panel 210 can also adopt a lightweight solar photovoltaic panel, and its front panel 211 and back panel 215 are made of lightweight materials with smaller densities such as PET, PC, ETFE, and FEP. The solar photovoltaic panel 210 can also adopt a flexible solar photovoltaic panel. Multiple small-sized solar photovoltaic panel units are interconnected or fixed to a flexible substrate to form a solar photovoltaic panel 210. The flexible substrate can adopt cloth, plastic film, iron sheet, aluminum sheet, etc. The solar photovoltaic panel 210 can also adopt a flexible solar photovoltaic panel. Multiple small-sized solar photovoltaic panel units are electrically connected to form two independent power-generating sections that are led out. The front and back of the two sections are covered with a composite film and laminated to form a solar photovoltaic panel 210. More preferably, wear-resistant materials such as metal strips, rubber bands, rubber, and nylon are fixed on the lower side of the solar photovoltaic panel.

[0074] Conventionally, 6 strings of battery cells are arranged in a series-parallel manner. Since the solar photovoltaic panel 210 in this embodiment needs to be placed vertically on its side in the vehicle (which will be described in detail below), it is restricted by the height of the vehicle compartment of the vehicle 100. The battery cells 213 of the solar photovoltaic panel 210 can be designed to have 2 to 5 strings, and in this embodiment, it is designed to have 4 strings, as shown in the appendix Figure 6 shown.

[0075] The connecting mechanism 220 includes a support rod 221. The solar photovoltaic panel 210 is connected to the support rod 221 through a rigid structure and a hinge / flexible material, or directly connected to the support rod 221 through a flexible material. Preferably, the support rod 221 is fixed at the middle position of the solar photovoltaic panel 210, and the support rod 221 is connected below the solar photovoltaic panel 210. The composite film can not only connect two adjacent solar photovoltaic panels 210 but also serve as the flexible material used for the above connection, as shown in the appendix Figure 7 and appendix Figure 7.1 and appendix Figure 7.2 shown.

[0076] In a more preferred embodiment, the solar photovoltaic module 200 further includes a fixing device for fixing it in a retracted state to prevent the solar photovoltaic panels 210 from colliding with each other and being damaged and from being scattered during handling. The fixing device can adopt ropes, buckles, pressing blocks, nylon stickers, etc.

[0077] When the solar power supply device is in the standby state, all the solar photovoltaic modules 200 are vertically placed in the vehicle 100 to prevent damage caused by bumps during transportation. In a more preferred embodiment, a first suspension device for hanging the solar photovoltaic modules 200 is further provided in the vehicle 100, as shown in the attached Figure 8 Figure Figure 8 shows a specific structure of a first suspension device, including a support beam 110 and a pressing block 111 that can move up and down relative to the support beam 110. A hanging block 222 is correspondingly connected to the solar photovoltaic module 200. Preferably, the hanging block 222 is connected to the above-mentioned connecting mechanism 220. The hanging block 222 is hung on the support beam 110, and the pressing block 111 slides down to press the hanging block 222 against the support beam 110, thereby preventing the solar photovoltaic module 200 from bouncing up and down in the vehicle during bumps in transportation. The solar photovoltaic module 200 can also be hung on a trolley device and placed in the vehicle 100 together with the trolley device, which will be specifically introduced below.

[0078] In a more preferred embodiment, the solar photovoltaic module 200 further includes a roller device 230 for assisting the deployment and retraction of the solar photovoltaic module. The roller device 230 is arranged on the connecting mechanism 220. The roller device 230 is mainly for conventional solar photovoltaic panels and lightweight solar photovoltaic panels. Preferably, the rollers are arranged on the above-mentioned support rods 221. More preferably, the roller device 230 is arranged on every other support rod 221. The roller device 230 is mainly applied to manual deployment and retraction.

[0079] In a more preferred embodiment, the movable off-grid power generation and energy storage power supply system further includes a trolley device 400 for assisting the deployment and retraction of the solar photovoltaic module, as shown in the attached Figure 9 to Figure 12 , the trolley device 400 includes a trolley body 410 and a retracting and releasing mechanism 420. The trolley body 410 has a handle 411. When the solar photovoltaic module 200 transitions from the retracted state to the deployed state, one end of the solar photovoltaic panel 210 is laid flat and fixed on the ground. The trolley device 400 moves so that the remaining solar photovoltaic panels 210 are successively separated from the trolley body 410 and laid flat on the ground. When the solar photovoltaic module 200 transitions from the deployed state to the retracted state, both ends of the retracting and releasing mechanism 420 are respectively connected to the trolley body 410 and the connecting mechanism 220, and the solar photovoltaic panels 210 are successively pulled up and retracted onto the trolley body 410 by the lifting of the retracting and releasing mechanism 420. In an embodiment shown in the attached Figure 10 and 11 , a number of balls 412 for assisting the movement of the solar photovoltaic module 200 thereon are arranged on the bearing surface of the trolley body 410, so the above-mentioned roller device 230 can be omitted. In another embodiment shown in the attached Figure 12In an embodiment, for the flexible solar photovoltaic panel 210 and the lightweight solar photovoltaic panel 210 with a connection mechanism 220 that does not adopt a rigid structure, a second suspension device 430 is provided on the trolley body 410. When the solar photovoltaic module 200 transitions from the deployed state to the retracted state, both ends of the retracting and deploying mechanism 420 are respectively connected to the second suspension device 430 and the connection mechanism 220, and the solar photovoltaic panels 210 are pulled up one by one and retracted onto the second suspension device 430 to ensure that the photovoltaic modules do not collapse. If a trolley device 400 with a second suspension device 430 is adopted, the above-mentioned roller device 230 and the first suspension device in the vehicle 100 can also be omitted. As shown in the appendix Figure 8.1 As shown, the trolley device 400 equipped with the retracted solar photovoltaic module 200 is inside the carriage of the vehicle 100, and the solar photovoltaic module 200 is hung on the second suspension device 430 through the support rod 221.

[0080] In a more preferred embodiment, as shown in the appendix Figure 13 to the appendix Figure 15 As shown, the vehicle 100 is provided with a switchable ramp door 105. When the ramp door 105 is opened, one end of the ramp door 105 is connected to the vehicle 100 and the other end abuts against the ground, for the trolley device 400 to be pushed into or pulled out of the vehicle 100 along the ramp door 105. Specifically, a motor 106 is provided on the vehicle 100, and the trolley device 400 is pulled in or out by retracting and deploying the cable 107 through the motor 106. Preferably, the ramp door 105 is provided with an elongation device that elongates during the opening process to reduce the slope and facilitate the pushing of the trolley device 400 up and down. The elongation device can be a folding mechanism or can be designed as a stretching mechanism.

[0081] In another embodiment, as shown in the appendix Figure 16 to the appendix Figure 19 As shown, the vehicle 100 is provided with a hoisting device 120 for hoisting the solar photovoltaic module 200 or / and the trolley device 400 into the vehicle 100. The hoisting device 120 includes a telescopic rod 121 connected to the upper part of the vehicle 100 and an electric hoist 122 connected to the end of the telescopic rod 121.

[0082] Whether the ramp door 105 or the hoisting device 120 is adopted, if the trolley device 400 and the solar photovoltaic module 200 are transported into the vehicle 100 together, fixing devices for fixing the trolley device 400 to the vehicle 100 and fixing the solar photovoltaic module 200 to the trolley device 400 need to be provided inside the vehicle 100.

[0083] The solar photovoltaic module 200 is the main power supply device of a mobile off-grid power generation, energy storage, and power supply system. However, in order to charge through light at the application point and avoid the risk of the battery starving due to long-term non-use, in an embodiment as shown in the appendixFigure 20 and 21 In the more preferred embodiment shown, the solar power supply device also includes a first solar photovoltaic component 501 arranged on the top of the vehicle 100 and a second solar photovoltaic component 502 that can be supported and arranged on the side of the vehicle 100. The second solar photovoltaic component 502 has at least two working states. When it is in the first working state, it is close to the side of the vehicle 100. When it is in the second working state, it is supported by a supporting device 503 and away from the side of the vehicle 100, so that its light-emitting surface faces the sunlight.

[0084] In a more preferred embodiment, the mobile off-grid power generation and energy storage system further includes a wind power supply device 600 disposed on the vehicle 100, as shown in the attached Figure 22 As shown, the wind power supply device 600 includes a controller (not shown in the figure), a telescopic support 601 that can be detachably connected to the vehicle 100, a generator 602 connected to the telescopic support 601, and a rotatable 603. When power generation is required, the telescopic support 601 raises the generator 602 and fan blades 603 to a high altitude, and the wind blows the fan blades 603 to drive the generator 602 to generate electricity. The wind power supply device 600 can be placed inside or outside the vehicle 100. When the wind power generation system is placed inside the vehicle 100, as shown in the attached figure, Figure 23 As shown, an upper cover door 108 is provided on the top of the vehicle 100 located above the wind power generation system. When wind power generation is required, the upper cover door 108 on the top of the vehicle 100 is opened, and then the telescopic support 601 is opened. The electricity generated by the wind power supply device 600 is charged to the application end through the control inverter device.

[0085] The power module can be customized according to customer needs, and the capacity can be 10AH to 600AH. The power module is preferably placed in the vehicle 100 and separated by a partition.

[0086] The control inverter module is used to control and protect the electricity output by the solar photovoltaic module 200, the power module, and the power output module. It transforms the electricity generated by the solar photovoltaic panel 210, inverts the DC power of the power module and outputs it to the application end to achieve AC output. It also protects the power module and the power output module from overcurrent, overvoltage, reverse charging, and reverse connection. The control inverter module is also equipped with a direct charging function. The electricity generated by the solar photovoltaic panel 210 is first charged to the application end through the control inverter module, and any excess electricity is then provided to the power module. The control inverter module also includes a heat dissipation device for dissipating heat from the power module and electrical components. The control inverter module also outputs electricity of different voltages and different phase numbers according to the electricity standards of different countries and regions and the input requirements of different electrical appliances.

[0087] The electric energy output module includes a plug for connecting to the application end. The plug includes a 5V USB interface, a 12V interface, a 220V two-hole socket, a 220V three-hole socket, an air conditioner socket, and a socket matching the new energy vehicle charging pile, etc. The plug is connected to the control and inversion device through a cable 165. The cable 165 is pulled out from the vehicle 100 and directly led to a designated location. As shown in the appendix Figure 15 As shown, the cable 165 can be automatically retracted into the vehicle 100 through a cable reel 166.

[0088] The vehicle 100 can move by setting its own driving mechanism, or be driven to move by being towed behind an automobile, or be installed in the carriage of a freight vehicle.

[0089] The vehicle 100 can be a trailer, a motorhome, a station wagon, a freight vehicle, a nanny car, etc. When the vehicle is a trailer, a driving system can also be installed on the trailer, and the trailer can be directly driven to move through its own driving system. In this embodiment of the attached drawing, the trailer is taken as an example for illustration, including a frame 101, wheels 102 connected below the frame 101, and a carriage 103 connected to the frame 101. A partition is arranged inside the carriage 103 for separating components such as the solar photovoltaic module 200, the power supply module, and the control and inversion device. A display screen 161, a plurality of control buttons 162 (including an emergency stop switch, a circuit breaker, etc.), a heat dissipation port 163, and the socket 164 described above are arranged on the outside of the carriage 103. A protective cover is also arranged on the outside of the carriage 103 to cover the display screen, the plurality of control buttons, the heat dissipation port, the socket, etc., to prevent the electrical components from being exposed outside for a long time and being invaded by rainwater, resulting in electric leakage.

[0090] A shock absorption device 140 and a towing device 130 are arranged on the frame 101. The middle part of the shock absorption device 140 cooperates with the axle 104, and both sides of the shock absorption device 140 cooperate with the frame 101. As shown in the appendix Figure 8.1 In it, the shock absorption device 140 is a shock absorption leaf spring; the towing device 130 cooperates with the rear of the automobile and the platform system. The towing device 130 is also designed with a braking mechanism 150, and the braking mechanism 150 cooperates with the axle 104. A tail light 109 is also arranged on the frame 101. More preferably, a groove is designed in the middle of the frame 101 to place the power supply module or the control and inversion module.

[0091] The braking mechanism 150 includes a manual braking mechanism and an automatic braking mechanism. After being separated from the automobile, the trailer is braked through the manual braking mechanism to prevent it from slipping; the automatic braking mechanism is connected to the braking mechanism of the automobile. When the automobile brakes, the trailer brakes simultaneously to prevent the trailer from continuing to rush forward and hitting the automobile when the automobile brakes.

[0092] This movable off-grid power generation, energy storage and power supply system has the following advantages compared with the prior art:

[0093] 1. It has a large storage capacity and high power generation, can charge electric vehicles, and can meet the electricity demand for the daily life of 3-4 ordinary families, including turning on air conditioners.

[0094] 2. It is convenient to transport and can be fixed to the back of a car or placed on a truck or lorry for transportation.

[0095] 3. The way the internal solar photovoltaic module unfolds and folds is simple and easy to operate.

[0096] 4. It is provided with multiple lead-out ports, which is convenient for users to connect various electrical appliances.

[0097] 5. The solar photovoltaic panel material uses lightweight materials, which can greatly reduce the weight of the panel and at the same time reduce the weight of the whole trailer system vehicle.

[0098] 6. When the solar photovoltaic module is in the retracted state inside the vehicle, it is vertical, and during transportation, it can greatly reduce the damage caused by bumps (if the solar photovoltaic panel is placed flat, it is easy to cause the battery cells inside the photovoltaic panel to rupture during up and down bumps).

[0099] 7. Combined with a wind power generation system, it provides a relatively quiet power supply for users, which is an alternative to the noise of traditional gasoline and diesel generators, and is especially suitable for environments that require quietness and low noise.

[0100] 8. When not in use for a long time, the battery is still discharging continuously. If not charged for a long time, the storage battery will starve to death and be scrapped. The solar photovoltaic module set on the vehicle roof can charge the battery at any time to ensure that the battery will not starve to death.
