Description

Technical Field

[0001] The present invention relates to the technical field of energy storage power supplies, and specifically to a multi-scenario and multi-functional energy storage power supply and its working method. Background Art

[0002] An energy storage power supply is a large-capacity mobile power supply, a machine that can store electrical energy. Its working principle is to output AC 220V, which can drive a small-power rice cooker to cook rice, a coffee machine to make coffee, can be used for lighting, can use a power socket, and can charge a variety of electrical appliances.

[0003] Most of the usage scenarios of energy storage power supplies are outdoors. People usually need to use energy storage power supplies when traveling or camping outdoors. The Chinese patent CN218888892U, a portable multi-functional energy storage power supply, mentions: "A power supply body, a heat dissipation fan is arranged at the front end of the outer wall of the power supply body, and further includes a handle storage cavity, a lifting component, a storage box, a dragging component, a storage groove and a moving component. The handle storage cavity is fixed at the top of the outer wall of the power supply body, the lifting component is arranged on the inner wall of the handle storage cavity, the storage box is fixed at the side end of the outer wall of the handle storage cavity, and the dragging component is arranged in the storage box. Through the above method, it can be seen that the present utility model enables users to pull the power supply body for movement, so that users do not need to lift the power supply body for a long time, thereby avoiding the situation where the arms become sore when users carry the power supply body for a long time, and further facilitating the carrying and use by users."

[0004] Based on the retrieval of the above patent and combined with the actual situation of using energy storage power supplies in the prior art, we found that there are still certain defects in such energy storage power supplies:

[0005] First of all, the energy storage power supply described above only facilitates the handling of the energy storage power supply before or after use, but ignores the problems that are likely to occur during the use of the energy storage power supply. Since the discharge of the energy storage power supply is large, the air circulation speed inside the energy storage power supply will be affected by the airtightness of the shell, resulting in low circulation efficiency. This will cause heat to concentrate inside the energy storage power supply and be difficult to discharge, and there will be a risk of battery expansion or circuit short circuit due to excessive heat. Therefore, corresponding measures should be taken in a timely manner before such situations occur; at the same time, such energy storage power supplies usually only have the function of supplying power to electrical equipment, and this function is relatively single and difficult to meet other needs of people during leisure and entertainment.

A movable plate two 28 is hinged on the movable plate one 27. Solar photovoltaic panels 29 are arranged on both the movable plate one 27 and the movable plate two 28.

[0042] In this embodiment, a lamp head 4, an audible and visual alarm 32, and a display panel 5 are also installed at the top of the side of the front panel 3.

The set speakers 9 can cooperate with the video playback effect of the projector main body 7 to achieve an audio playback effect, enhancing the functionality of the device.

[0046] In this embodiment, hollow fixing rods 13 are fixed on both sides of the inner cavity of the energy storage power supply main body 1 and close to the battery assembly 11. A fire extinguishing nozzle 1301 with an air outlet facing the battery body 20 is connected to each hollow fixing rod 13. The output channel of the carbon dioxide fire extinguisher 14 is fixedly connected to the hollow fixing rod 13.

The signal input end of the PLC controller 17 is connected to a smoke sensor 12 installed on the inner top wall of the energy storage power supply main body 1 through a wire.

[0047] Specifically, by setting the smoke sensor 12 on the top of the inner cavity of the energy storage power supply main body 1, according to the characteristic that smoke rises, when smoke appears in the inner cavity of the energy storage power supply main body 1, it can be timely sensed by the smoke sensor 12. Then, the PLC controller 17 is used to timely open the solenoid valve 15, so as to release the carbon dioxide stored in the carbon dioxide fire extinguisher 14. The released carbon dioxide enters the hollow fixing rod 13 through the output channel and enters each fire extinguishing nozzle 1301 through the guidance of the hollow fixing rod 13, facilitating the filling of carbon dioxide in the inner cavity of the energy storage power supply main body 1 and achieving a fire extinguishing effect.

[0048] In this embodiment, support plates 16 are fixed at the bottoms of both sides of the inner wall of the energy storage power supply main body 1.

Cooling openings 10 are formed at both the left and right sides of the outer wall of the energy storage power supply main body 1 and corresponding to the fixing frames 1601.

[0049] Specifically, by means of the provided fixed frame 1601 and the cooling fan 1603, the heat located inside the energy storage power supply main body 1 can be effectively exported by the rotation of the cooling fan 1603, which is beneficial to the stable operation of the components inside the energy storage power supply main body 1. The filter screen 1602 is provided on the fixed frame 1601 to prevent external impurities from entering the energy storage power supply main body 1.

[0050] In this embodiment, feet 30 are fixed to both the top and bottom of one side of the movable plate 27, and pins 31 are fixed to both the top and bottom of one side of the movable plate 28. Limit holes 3101 are provided at both the top and bottom of the pins 31; cavities 23 are provided at positions corresponding to the two pins 31 in the inner cavity of the fixed plate 21. A return spring 24 is fixed inside the cavity 23, and one end of the return spring 24 is fixed with a sliding block 25 slidably connected in the cavity 23. A thimble 26 is fixed to the sliding block 25; a slot convenient for the pins 31 to be inserted is further provided on the side surface of the energy storage power supply main body 1. When the movable plate 28 places the pins 31 in the slot by bending, the round head end of the thimble 26 is placed in the limit holes 3101 provided on the pins 31. When the movable plate 27 and the movable plate 28 flatten the two solar photovoltaic panels 29 by bending, the feet 30 and the pins 31 support on the ground, and an inverter used in cooperation with the solar photovoltaic panels 29 is further provided inside the energy storage power supply main body 1.

[0051] Specifically, since the movable plate 27 and the movable plate 28 can be bent and stored, that is, the solar photovoltaic panels 29 on the plate body can be fitted and protected when not in use, which is convenient for subsequent use. The provided fixed block 22 plays a role in supporting the movable plate 27 and the movable plate 28, and the provided thimble 26 can be inserted into the limit holes 3101 on the pins 31 to fix the pins 31, so that the movable plate 27 and the movable plate 28 are stably fitted on the fixed plate 21 after being bent.

[0052] In this embodiment, the back surface of the battery assembly 11 is snap-fitted to the back inner wall of the energy storage power supply main body 1, the front surface of the battery assembly 11 is fixed to the back surface of the front panel 3 by screws. A plurality of battery slots 1102 on the battery fixing frame 1101 are arranged at intervals, and the temperature sensors 1103 in the battery slots 1102 are in close contact with the battery bodies 20 in the battery slots 1102; the signal output end of the temperature sensor 1103 is connected to the PLC controller 17 through a wire, and the signal output end of the PLC controller 17 is connected to the sound and light alarm 32 through a wire.

[0053] Specifically, since a temperature sensor 1103 is attached to each battery body 20, the temperature of a single battery body 20 can be monitored using the individual temperature sensor 1103, and the temperature monitoring effect is better and more accurate. When the temperature of a certain battery body 20 exceeds the rated value, an alarm can be issued in a timely manner through the sound and light alarm 32, thereby enhancing the overall safety. When maintenance is required, the staff can remove the front panel 3, thereby exposing the inner cavity of the energy storage power supply main body 1, and the battery assembly 11 placed inside the energy storage power supply main body 1 can be taken out through the removed front panel 3, achieving the purpose of convenient overall disassembly for maintenance and repair.

[0054] To achieve the above object, a working method of a multi-scenario and multi-functional energy storage power supply is provided.

[0055] It includes the following steps:

[0056] Use scenario one:

[0057] When using this device as a power supply device, the plug of the electrical device can be inserted into the socket panel 8, and the battery assembly 11 inside the energy storage power supply main body 1 is used to supply power to the electrical device, and the status is displayed through the display panel 5. At the same time, when the handheld device needs to be charged, the data cable is inserted into the USB interface 601, and the USB interface 601 is used to supply power to the handheld device, and the status is displayed through the display panel 5;

[0058] When the energy storage power supply main body 1 supplies power to the electrical device, in order to ensure the normal operation of the device, multiple temperature sensors 1103 detect the temperature of each battery body 20 in real time. When the temperature is higher than the rated value, a signal can be sent to the PLC controller 17 in a timely manner, and the PLC controller 17 is used to start the sound and light alarm 32, so as to issue an alarm to the user through the sound and light alarm 32 in a timely manner, reminding the user to reduce the connection of the electrical device or disconnect the circuit connection with the energy storage power supply main body 1, achieving the effect of reducing the temperature of the battery body 20. The smoke sensor 12 detects the smoke situation inside the energy storage power supply main body 1 in real time. When a short circuit and fire occur in the circuit or the battery body 20, the generated smoke can be detected by the smoke sensor 12, and a signal is sent to the PLC controller 17 in the first time. The solenoid valve 15 is opened through the PLC controller 17, thereby opening the carbon dioxide output channel, so that carbon dioxide flows out of the carbon dioxide fire extinguisher 14 and is transported to each fire extinguishing nozzle 1301 through the hollow fixing rod 13. Since the fire extinguishing nozzle 1301 is close to the battery body 20, the carbon dioxide ejected from the fire extinguishing nozzle 1301 can instantly fill the gap between the battery body 20 and the battery body 20, and gradually fill the inside of the energy storage power supply main body 1 as it diffuses, thereby achieving the purpose of timely extinguishing the fire by transporting carbon dioxide into the inside of the energy storage power supply main body 1;

[0059] Usage Scenario 2:

[0060] When using this device as a projection device, the user can use the mobile phone to search for the Bluetooth module 18 on the device. The Bluetooth module 18 transmits the signal to the projector main body 7 through the PLC controller 17. By starting the projector main body 7, the video on the mobile phone side can be played, and the sound can be emitted through the speaker 9.

[0061] Usage Scenario 3:

[0062] When charging this device, the charging cable connected to the energy storage power supply main body 1 can be inserted into the indoor socket using the traditional charging method. In special cases, the solar charging component can be unfolded to charge the battery body 20 on the battery component 11 using the solar photovoltaic panel 29. When using the solar charging component, the movable plate 2 can be pulled backward, and the movement of the movable plate 2 causes the pin 31 to disengage from the slot on the fixing plate 21, that is, the thimble 26 disengages from the limit hole 3101. Then the user continues to fold the movable plate 1 and the movable plate 2, and after the movable plate 2 rotates through the hinge to be flush with the movable plate 1, the movable plate 1 and the movable plate 2 can be placed on the ground. The support feet 30 and the pins 31 can act as a temporary support structure. When sunlight shines on the solar photovoltaic panel 29, the inverter can be used to transmit electrical energy into the battery body 20 to store electrical energy.

[0063] It should be noted that regardless of the usage environment of the energy storage power supply main body 1, the cooling fan 1603 can be started to discharge the heat accumulated inside the energy storage power supply main body 1, so as to cooperate with the heat dissipation fins 19 to greatly discharge the heat inside the energy storage power supply main body 1, achieving the purpose of providing a stable temperature working environment for the internal components of the energy storage power supply main body 1.

[0064] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
