Description
Technical Field
[0001] This invention belongs to the field of energy storage power supply and relates to a household energy storage power supply. Background Technology
[0002] An energy storage power supply is a high-capacity mobile power source, a machine that can store electrical energy. It can provide AC 220V output, drive low-power electrical appliances, be used for lighting, use power sockets, charge various electrical appliances, and has all the functions of an online UPS. It provides stable power protection for critical loads, optimizes UPS performance, and reasonably saves investment in oil pumps, reactive power compensation equipment, and voltage stabilizing equipment.
[0003] Current home energy storage power supplies have many shortcomings in outdoor use scenarios: Traditional energy storage power supplies, if they need to be equipped with solar charging functions, often require carrying separate solar panels, which not only increases the burden of carrying them, but also makes the outdoor assembly process cumbersome and has poor adaptability; some energy storage power supplies with integrated solar panels often have fixed or simply folded structures, with limited light-receiving area and inconvenient angle adjustment, making it difficult to make full use of sunlight at different times of day, resulting in low power generation efficiency and insufficient range when using energy storage power supplies outdoors; at the same time, the casing design of existing energy storage power supplies often does not consider the coordination between photovoltaic panel storage and the protection and heat dissipation of internal components, making the internal battery components susceptible to the impact on lifespan due to high-temperature environments, and lacking independent protective structures for the batteries, posing safety hazards. In addition, in traditional home energy storage power supplies, the battery heat dissipation during use relies entirely on the discharge of the internal energy storage battery, further aggravating the range reduction.
[0004] Therefore, the present invention provides a household energy storage power supply to solve the above problems. Summary of the Invention
[0005] In view of the problems existing in the prior art, the present invention discloses a household energy storage power supply. The technical solution adopted is as follows: the energy storage power supply body includes a trapezoidal shell. The left side wall of the trapezoidal shell is a rightward inclined surface. A pin is screwed into the middle of the upper end of the bottom of the trapezoidal groove of the inclined surface. A photovoltaic power generation component composed of several stacked fan-shaped photovoltaic panels is rotatably mounted on the pin. The photovoltaic power generation component includes a fan-shaped photovoltaic panel with an outer contour smaller than the trapezoidal groove. The end of the fan-shaped photovoltaic panel near the center is rotatably mounted on the pin. The fan-shaped photovoltaic panel rotates counterclockwise around the pin to unfold into a circular photovoltaic panel. The centers of the bottom edges of the back of adjacent fan-shaped photovoltaic panels are connected in sequence by wires. A guide tube is fixedly installed on the upper part of the back of the fan-shaped photovoltaic panel inside the trapezoidal groove. The guide tube is movably inserted into the bottom of the groove. A positioning hole is opened at the lower right corner of the outermost fan-shaped photovoltaic panel. A positioning screw is inserted into the positioning hole. The end of the positioning screw is screwed into a fixing lug installed on the lower part of the rear side wall of the trapezoidal shell.
[0006] As a preferred embodiment of the present invention, the central angle of the fan-shaped photovoltaic panel is 30 degrees, and 12 panels are provided.
[0007] As a preferred embodiment of the present invention, a partition is provided in the middle of the interior of the trapezoidal shell, and several through holes are formed in the upper right side wall of the shell.
[0008] As a preferred embodiment of the present invention, a controller is installed on the upper part of the partition, and the controller integrates a main control module, a charging controller and an inverter.
[0009] As a preferred embodiment of the present invention, a cooling fan is installed at the lower part of the partition, and the exhaust port at the lower part of the cooling fan is directly opposite the energy storage battery assembly installed at the bottom of the trapezoidal housing.
[0010] As a preferred embodiment of the present invention, the controller is electrically connected to a wire extending from the guide tube via a wire; this design enables an electrical connection between the controller and the fan-shaped photovoltaic panel.
[0011] As a preferred embodiment of the present invention, the energy storage battery assembly includes a trapezoidal isolation protective shell, with a plurality of heat dissipation holes respectively opened on the front and rear side walls of the trapezoidal isolation protective shell, and an air inlet hole opened on the top of the trapezoidal isolation protective shell. The front and rear heat dissipation holes respectively penetrate the front and rear side walls of the trapezoidal shell, and a plurality of columnar batteries connected in series are arranged inside the trapezoidal isolation protective shell.
[0012] As a preferred embodiment of the present invention, the front side wall of the trapezoidal housing has a touch panel with an external power supply socket, and the upper part of the right side wall of the trapezoidal housing has an external power cord with a plug.
[0013] The beneficial effects of this invention are:
[0014] The trapezoidal groove on the left side wall of the trapezoidal shell provides a suitable storage space for photovoltaic power generation modules made up of several stacked fan-shaped photovoltaic panels. Twelve fan-shaped photovoltaic panels with a central angle of 30 degrees can be rotated counterclockwise around the pin to form a circular photovoltaic panel, which greatly increases the light-receiving area and improves power generation efficiency. Adjacent fan-shaped photovoltaic panels are connected in series by wires. When in use, simply rotate the outermost fan-shaped photovoltaic panel counterclockwise, and the connection of the wires will enable the 12 adjacent fan-shaped photovoltaic panels to be quickly unfolded into a circular photovoltaic panel. When storing, unscrew the positioning screw of the outermost fan-shaped photovoltaic panel and rotate the fan-shaped photovoltaic panel clockwise to stack the fan-shaped photovoltaic panels together and embed them into the trapezoidal groove. This eliminates the need to carry additional photovoltaic panels and significantly improves portability.
[0015] The guide tube not only limits and fixes the unfolding and retraction of the fan-shaped photovoltaic panel, but also protects the wires. Adjacent fan-shaped photovoltaic panels are connected in series through the wires to ensure that the power is stably transmitted to the controller that integrates the main control module, charging controller and inverter, so as to achieve efficient power conversion.
[0016] The internal partition of the trapezoidal housing separates the controller from the cooling fan and the energy storage battery assembly. The cooling fan, through the air intake and heat dissipation holes, provides good heat dissipation for the energy storage battery assembly. The trapezoidal isolation protective shell provides independent protection for the cylindrical battery, improving the safety of use.
[0017] By rapidly unfolding a fan-shaped photovoltaic panel into a circular photovoltaic panel, it can provide supplemental power to cooling fans or power devices with low demand such as outdoor lighting and mobile phone charging, thereby reducing the power required by the energy storage battery for heat dissipation and thus improving the battery life of the energy storage power supply.

Detailed Implementation
[0025] Example 1
[0026] like Figures 1 to 6As shown, the technical solution of the household energy storage power supply of the present invention includes an energy storage power supply body 1, which includes a trapezoidal shell 11. The left side wall of the trapezoidal shell 11 is a right-inclined slope. A trapezoidal groove 12 is formed on the slope, and a pin 13 is screwed into the middle of the bottom of the groove. A partition 14 is provided in the middle of the interior of the trapezoidal shell 11. Several through holes 15 are formed on the right side wall of the upper part of the partition 14. A photovoltaic power generation module 2, which is composed of 12 fan-shaped photovoltaic panels with a central angle of 30 degrees, is rotatably mounted on the pin 13. The photovoltaic power generation module 2 includes a fan-shaped photovoltaic panel 21 whose outer contour is smaller than that of the trapezoidal groove 12. The fan-shaped photovoltaic panel 21 is rotatably mounted on the pin 13 at one end near the center. The fan-shaped photovoltaic panel 21 rotates counterclockwise around the pin to unfold into a circular photovoltaic panel. The centers of the bottom edges of the back sides of adjacent fan-shaped photovoltaic panels 21 are connected in series by wires 22. A guide tube 23 is fixedly installed on the upper part of the back side of the fan-shaped photovoltaic panel 21 inside the trapezoidal groove 12. The guide tube 23 is movably inserted into the bottom of the groove. A positioning hole 24 is opened at the lower right corner of the outermost fan-shaped photovoltaic panel 21. A positioning screw 25 is inserted into the positioning hole 24. The end of the positioning screw 25 is screwed into the fixing lug 26 installed on the lower part of the rear side wall of the trapezoidal housing 11.
[0027] A controller 3 is installed on the upper part of the partition 14. The controller 3 is electrically connected to a wire extending from the guide tube 23 via a wire. The controller 3 integrates a main control module, a charging controller, and an inverter. The main control module establishes signal connections with the charging controller and the inverter to achieve functional coordination. The input terminal of the charging controller is electrically connected to the fan-shaped photovoltaic panel 21 connected in series in the photovoltaic power generation module 2 via a wire extending from the guide tube 23 to receive the DC power generated by the photovoltaic panel. At the same time, the output terminal of the charging controller is connected to the trapezoidal isolation protective shell 51 in the energy storage battery module 5. The cylindrical battery 52 inside is electrically connected to the battery to deliver the processed electrical energy to the battery storage. The input of the inverter is electrically connected to the cylindrical battery 52 of the energy storage battery assembly 5 to obtain DC power and convert it into AC power. The output of the inverter is electrically connected to the external power supply socket on the touch panel 6 on the front side wall of the trapezoidal housing 11 and the external power line 7 on the upper right side wall to supply power to external electrical equipment. In addition, the main control module is also electrically connected to the cooling fan 4, which can control the start, stop and speed of the cooling fan 4 according to the temperature signal of the energy storage battery assembly 5 to ensure the stable operation of the overall electrical system.
[0028] A cooling fan 4 is installed at the lower part of the partition 14. The exhaust port at the lower part of the cooling fan 4 is directly opposite the energy storage battery assembly 5 installed at the bottom of the trapezoidal housing 11. The energy storage battery assembly 5 includes a trapezoidal isolation protective shell 51. A temperature detection sensor is built into the trapezoidal isolation protective shell 51. Several heat dissipation holes 511 are opened on the front and rear side walls of the trapezoidal isolation protective shell 51. An air inlet 512 is opened on the top of the trapezoidal isolation protective shell 51. The front and rear heat dissipation holes 511 respectively penetrate the front and rear side walls of the trapezoidal housing 11. Several columnar batteries 52 connected in series are arranged inside the trapezoidal isolation protective shell 51.
[0029] The front wall of the trapezoidal housing 11 has a touch panel 6 with an external power supply socket, and the upper part of the right side wall of the trapezoidal housing 11 has an external power cord 7 with a plug.
[0030] The working principle of this invention is as follows: When using this household energy storage power supply outdoors, first unscrew the positioning screw 25 installed on the fixing ear 26. At the same time, rotate the pin 13 outward to bring the stacked fan-shaped photovoltaic panels 21 out of the trapezoidal groove 12. Then, rotate several fan-shaped photovoltaic panels 21 stacked in the trapezoidal groove 12 counterclockwise around the pin 13 to unfold them until a circular photovoltaic panel is formed. Then, pass the positioning screw 25 through the positioning hole 24 on the outermost fan-shaped photovoltaic panel 21 and screw it back into the fixing ear 26. During the unfolding process, the wire 22 in the middle of the bottom back of adjacent fan-shaped photovoltaic panels 21 can both connect adjacent fan-shaped photovoltaic panels 21 and conduct electricity in series. After unfolding, the angle of the photovoltaic panel can be adjusted according to actual needs to fully receive sunlight. When the photovoltaic power generation module 2 is working, the 12 fan-shaped photovoltaic panels 21 transmit the generated electrical energy through the wire 22 connected in series at the center of the bottom edge of the back. The electrical energy is then electrically connected to the controller 3 through the wire in the guide tube 23. The charging controller in the controller 3 processes the electrical energy. After processing, a portion is used to charge the energy storage battery assembly 5. The cylindrical cells 52 in the energy storage battery assembly 5 store electrical energy under the protection of the trapezoidal isolation protective shell 51. The other portion can be converted from DC to AC by the inverter in the controller 3. Users can connect electrical equipment through the external power supply socket on the touch panel 6 on the front side wall of the trapezoidal shell 11 or the external power cord 7 on the upper right side wall to achieve power supply. During the operation of the equipment, the cooling fan 4 at the bottom of the partition 14 works, which will draw in external airflow from the through hole 15. Air is blown into the trapezoidal protective housing 51 through the air inlet 512 and then discharged through the heat dissipation holes 511 on the front and rear side walls to dissipate heat for the energy storage battery module 5 and ensure stable operation of the equipment. After use, the positioning screw 25 installed on the fixing ear 26 is unscrewed again, and the fan-shaped photovoltaic panel 21 is rotated clockwise around the pin 13 and stored back into the trapezoidal groove 12. Then, the pin 13 is tightened to fix the photovoltaic power generation module 2 stacked in the trapezoidal groove 12. Finally, the positioning screw 25 is screwed into the fixing ear 26 to complete the fixed storage.
