Description

Technical Field

[0001] This invention relates to the field of DC boost converters, and more particularly to a DC boost converter suitable for mobile optical storage. Background Technology

[0002] A DC-DC boost converter (also known as a Boost converter or DC-DC boost converter) is a non-isolated switching power supply circuit that boosts the input DC voltage to a higher output voltage. It is a type of DC-DC converter, and its core achieves voltage boosting through high-frequency switching (such as MOSFETs), inductor energy storage, diode freewheeling, and capacitor filtering.

[0003] A photovoltaic energy storage cabinet is disclosed in patent publication number CN118971732B, which includes a main component, a cabinet component, a cooling air component fixedly connected to the left side of the inner cavity of the cabinet component, a storage component fixedly connected to the middle of the inner cavity of the cabinet component, a self-cleaning component provided on the top of the cabinet component, and a grille component, which is provided on the left and right sides of the cabinet component.

[0004] However, the aforementioned devices still have certain drawbacks in use. Photovoltaic power generation equipment typically outputs electrical energy with low voltage and high current. After being boosted, it becomes electrical energy with high voltage and low current. Since DC boosting equipment often outputs high-voltage electrical energy, there is a risk of electric shock to technicians if effective isolation is not implemented during its operation. However, even with effective isolation, it is impossible to effectively monitor the temperature of the internal wires used to transmit electrical energy. This is because the current in photovoltaic energy storage generates heat during its flow. Under prolonged operation, if the wires transmitting electrical energy are not effectively monitored, the wires are prone to short circuits due to heat damage to the outer sheath. Most accidents in existing energy storage technologies are caused by short circuits due to wire damage. Summary of the Invention

Multiple air holes are equidistantly opened on the side wall of the sealing cover. An evaporator is provided on the outside of the sealing cover. The evaporator is fixedly connected to the top wall panel of the mobile cabinet and is located outside the sealing cover. An annular groove is opened on the top wall panel of the mobile cabinet. The groove is located between the evaporator and the sealing cover. A drain hole is connected to one side of the groove. The drain hole is opened in the top wall panel of the mobile cabinet. A drain pipe is connected to the end of the drain hole away from the groove. A one-way valve is provided on the end of the drain pipe away from the drain hole.

[0012] Preferably, a rectangular photovoltaic panel is installed on the top of the mobile cabinet. Telescopic rods are fixedly connected to the four corners of the bottom of the photovoltaic panel.

[0015] Preferably, two adjustable electromagnetic switches are provided on both sides of the thermistor, and the two adjustable electromagnetic switches are used to electrically connect the two sides of the coil.

[0016] Preferably, the mobile cabinet is equipped with casters at all four corners of its bottom, and ventilation windows for ventilation and heat dissipation are provided on both sides of the bottom of the mobile cabinet.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This invention, through the arrangement of a coil and an iron core, generates magnetic force within the iron core as current flows through the coil. This magnetic force attracts the iron core to the fixed magnet, effectively adhering the door panel to the mobile cabinet, creating a magnetic door-like effect. This helps prevent accidental opening of the door panel during battery charging, thus avoiding static electricity buildup inside the cabinet that could cause air breakdown. Furthermore, the magnetic attraction also ensures the handle adheres to the light guide plate, preventing technicians from effectively opening the door and thus avoiding injury from static electricity within the cabinet.

[0019] 2. This invention utilizes the characteristic that the heat generated by the coil is slightly higher than that of other wires. By monitoring the heat generated during the coil's power transmission, it can effectively monitor the heat of the wires connecting the electrical components inside the mobile cabinet. This monitoring of the coil's heat allows for the monitoring of the wires connecting the electrical components inside the mobile cabinet, which helps to avoid the risk of the wires' insulation being burned by the heat generated during power transmission, thus preventing short circuits. On the one hand, this extends the service life of the device, and on the other hand, it effectively reduces the risk of short circuits.

[0020] 3. This invention, through the design of the bulb and light guide plate, allows the bulb's output power to increase, resulting in a change in the color of the light. The light emitted by the bulb is evenly dispersed on the light guide plate. This design makes it easier for technicians to distinguish the light, preventing the light from being indistinct and difficult to observe during the day due to sunlight. Furthermore, the change in light color allows technicians to effectively assess the temperature of the wires within the mobile cabinet. If the temperature becomes too high, technicians can determine whether to disconnect the input electromagnetic switch, thus preventing damage to the electrical components inside the mobile cabinet due to overheating. This also improves safety, helping to prevent short circuits caused by overheating. The light guide plate effectively disperses the light and allows technicians to observe the interior of the mobile cabinet. Moreover, the light guide plate is made of resin, so the iron core's magnetic force will not attract the light guide plate. Attached Figure Description

[0038] like Figures 1 to 11 The DC-DC boost converter for mobile optical storage shown includes a mobile cabinet 1 and a door panel 2 hinged to one side of the mobile cabinet 1. A boost module 10 is fixedly installed inside the mobile cabinet 1. A magnetic suction component is connected in series at the input end of the boost module 10. The magnetic suction component attracts the door panel 2 by magnetic force. A monitoring component is provided on one side of the magnetic suction component to monitor the temperature inside the mobile cabinet 1. A handle 21 adapted to the magnetic suction component is provided on the door panel 2. A light guide plate 20 is also embedded in the door panel 2. The handle 21 is installed on the outside of the light guide plate 20. A heat dissipation component is provided on the top of the mobile cabinet 1.

[0039] In specific implementation, the boost module 10 is a boost inverter used to convert low-voltage electricity generated by photovoltaics into high-voltage electricity. This technology is existing technology and will not be disclosed in detail here. The light guide plate 20 is made of acrylic sheet. There are two light guide plates 20, which are respectively embedded on the inner and outer sides of the door panel 2, and a gap is reserved between the two light guide plates 20.

[0040] As a further embodiment of the present invention, two partitions 12 are fixedly connected inside the mobile cabinet 1. The boost module 10 is located between the two partitions 12 and is fixedly connected to the top wall of the lower partition 12. Batteries 8 are fixedly connected to the top of the upper partition 12 and the bottom inner wall of the mobile cabinet 1. The batteries 8 are used to collect the power generated by the photovoltaic, and the two batteries 8 are connected in series with each other. One of the batteries 8 is connected in series with the output terminal of the boost module 10.

[0041] In practice, the two batteries 8 are located on the inner bottom wall panel of the mobile cabinet 1 and the top wall panel of the upper partition 12, respectively. The two batteries 8 can be installed in a detachable manner. After energy storage is completed, the batteries 8 can be removed and replaced with new batteries 8, similar to shared batteries in the prior art. This technology can be achieved through existing means, which will not be disclosed in detail here.

[0042] As a further embodiment of the present invention, the magnetic suction assembly includes a coil 18 connected in series with the input end of the boost module 10. An input electromagnetic switch 9 is connected in series at the end of the coil 18 away from the boost module 10. The input electromagnetic switch 9 is used for electrical connection with the photovoltaic. An iron core 23 is inserted inside the coil 18. The iron core 23 is fixedly connected to the inner wall of one side of the mobile cabinet 1 by a mounting plate. A fixed magnet 30 is embedded inside the handle 21. When the coil 18 is energized, the magnetic poles of the fixed magnet 30 and the iron core 23 are opposite to each other on the side closest to each other. Soft connecting strips 22 are fixedly connected to the top and bottom of the handle 21. The ends of the two soft connecting strips 22 away from the handle 21 are fixedly connected to the door panel 2, and the two soft connecting strips 22 are located on the upper and lower sides of the light guide plate 20, respectively. The iron core 23 and the fixed magnet 30 are located on the same vertical plane.

[0043] In practice, the flexible connecting strip 22 is made of rubber. It should be noted that the electromagnetic assembly, consisting of coil 18 and iron core 23, generates Joule heat primarily on coil 18 when the device is powered on. Because the photovoltaic system outputs direct current, the coil experiences no alternating hysteresis loss, resulting in a relatively low overall temperature rise. However, due to electromagnetic induction, the current density and eddy current effect of coil 18 are higher than those of conventional connecting wires, and its operating temperature is still significantly higher than that of other wires within the device.

[0044] As a further embodiment of the present invention, the monitoring component includes a thermistor 29 embedded in the inner wall of one side of the mobile cabinet 1. The thermistor 29 abuts against the outer wall of the coil 18. The thermistor 29 is connected in series with a bulb 17. The bulb 17 is fixedly connected to the partition 12 located below, and the bulb 17 is located inside the light guide plate 20. The light guide plate 20 is used to uniformly guide the light emitted by the bulb 17.

[0045] In practice, the thermistor 29 is specifically an inverse-ratio thermistor, whose resistance decreases as the temperature increases.

[0046] In another embodiment of the present invention, a temperature sensor and a controller can be embedded near the thermistor 29, and an alarm can be added. The alarm is communicatively connected to the controller. When the temperature sensor detects that the temperature of the thermistor 29 is too high, the temperature sensor sends a request message to the controller. After receiving the request message, the controller generates control information and then sends the control information to the alarm, so that the alarm can sound an alarm to further alert technicians. It should be noted that the temperature sensor has a preset temperature value. When it detects that the temperature of the thermistor 29 has reached the preset value, it generates the request message.

[0047] As a further embodiment of the present invention, the heat dissipation assembly includes a heat dissipation fan 25 fixedly embedded in the top of the mobile cabinet 1. A sealing cover 24 is provided on the top of the heat dissipation fan 25. A plurality of air holes 26 are equidistantly opened on the side wall of the sealing cover 24. An evaporator 7 is provided on the outside of the sealing cover 24. The evaporator 7 is fixedly connected to the top wall panel of the mobile cabinet 1 and is located outside the sealing cover 24. An annular groove 27 is opened on the top wall panel of the mobile cabinet 1. The groove 27 is located between the evaporator 7 and the sealing cover 24. A drain hole 13 is connected to one side of the groove 27. The drain hole 13 is opened in the top wall panel of the mobile cabinet 1. A drain pipe 28 is connected to the end of the drain hole 13 away from the groove 27. A one-way valve is provided at the end of the drain pipe 28 away from the drain hole 13.

[0048] In practice, the groove 27 is used to collect the water condensed from the evaporator 7, which then flows through the drain hole 13 and the drain pipe 28, and finally is discharged through the one-way valve.

[0049] As a further embodiment of the present invention, a rectangular photovoltaic panel 3 is installed on the top of the mobile cabinet 1. Telescopic rods 4 are fixedly connected to the four corners of the bottom of the photovoltaic panel 3. The fixed ends of the telescopic rods 4 are fixedly connected to the top wall panel of the mobile cabinet 1. The photovoltaic panel 3 is located directly above the evaporator 7. A power supply 14 is also fixedly connected to the bottom inner wall panel of the mobile cabinet 1. The power supply 14 is used to store the electricity generated by the photovoltaic panel 3, and to supply power to the bulb 17, the thermistor 29 and the cooling fan 25. The power supply 14 is also used to supply power to the evaporator 7.

[0050] In practice, the electrical energy generated by the photovoltaic panel 3 is stored through the power supply 14. It should be noted that the power supply 14 supplies power to the evaporator 7 separately. The power supply 14 has two parts: one part supplies power to the evaporator 7 separately, and the other part supplies power to the bulb 17, the thermistor 29 and the cooling fan 25.

[0051] As another embodiment of the present invention, the telescopic rod 4 is specifically an electric telescopic rod. When the device is not in use, by controlling the telescopic rod 4 to retract, the photovoltaic panel 3 is covered on the top of the evaporator 7, thereby effectively reducing the probability of dust falling inside the device when it is not in use.

[0052] As a further embodiment of the present invention, the cooling fan 25 is connected in series in the circuit of the thermistor 29 and the bulb 17, and the bulb 17 is specifically an RGB three-primary-color mixed light LED.

[0053] In practical implementation, RGB tri-color mixing LED beads have the characteristic that the color of the emitted light changes with the power. RGB tri-color mixing is currently the most widely used LED color-changing technology. Its core principle is to integrate LED chips of red, green, and blue primary colors together, and mix various colors by independently controlling the brightness ratio of each color. This technology is existing technology. This invention only uses the color of light to determine heat, and its principle will not be disclosed in detail here.

[0054] As a further embodiment of the present invention, the output terminal of the boost module 10 is connected in series with an output wire 16, the output wire 16 is connected in series with a resistor, the resistor is connected in parallel with an electrostatic generator 11, the boost module 10 is electrically connected to the storage battery 8 after being connected in parallel in the circuit, and is used to transmit electrical energy to the storage battery 8 for energy storage, the input terminal of the boost module 10 is connected in series with an input wire 15, and the end of the input wire 15 away from the boost module 10 is connected in series with a coil 18.

[0055] In practice, the two batteries 8 are connected in series, so when the photovoltaic power generation equipment supplies power to the device, both batteries 8 can effectively store energy.

[0056] As a further embodiment of the present invention, two adjustable electromagnetic switches 19 are provided on both sides of the thermistor 29, and the two adjustable electromagnetic switches 19 are used to electrically connect the two sides of the coil 18.

[0057] In practice, the two regulating electromagnetic switches 19 have built-in overload protection switches, and when electrically connected to the coil 18, they can also effectively protect the thermistor 29, the cooling fan 25, and the bulb 17. It should be noted that the coil 18 is connected in series with the thermistor 29 through the two regulating electromagnetic switches 19.

[0058] As a further embodiment of the present invention, casters 6 are provided at the four corners of the bottom of the mobile cabinet 1, and ventilation windows 5 for ventilation and heat dissipation are provided on both sides of the bottom of the mobile cabinet 1.

[0059] In practice, when the cooling fan 25 is working, the gas it blows into the mobile cabinet 1 will be discharged through the ventilation window 5. The ventilation window 5 can be designed with louvers. When the device is not used for energy storage, closing the louvers can effectively reduce dust from entering the interior of the mobile cabinet 1.

[0060] Working principle of this invention:

[0061] When using this invention, the output end of the photovoltaic power generation device is first connected to the input electromagnetic switch 9. Then, the electrical energy generated by the photovoltaic power generation device flows to the coil 18 through the input electromagnetic switch 9. Finally, the low-voltage electrical energy generated by the photovoltaic power generation device is converted into high-voltage electrical energy by the boost module 10 and sent to the battery 8 for energy storage. During this process, the heat dissipation component located on the top of the mobile cabinet 1 dissipates heat from the battery 8 and the boost module 10 inside the mobile cabinet 1.

[0062] After electrically connecting the output terminal of the photovoltaic power generation equipment to the input electromagnetic switch 9, close the door panel 2. During the process of current passing through the coil 18, the iron core 23 located inside the coil 18 generates a magnetic force, which in turn causes the magnetic force between the iron core 23 and the fixed magnet 30 to attract each other. On the one hand, this effectively attracts the door panel 2, making it firmly attached to the mobile cabinet 1, giving the door panel 2 an effect similar to a magnetic door. This helps to prevent the door panel 2 from being accidentally opened during the charging of the battery 8, which could lead to the static electricity inside the mobile cabinet 1 breaking down the air. On the other hand, the magnetic attraction also allows the handle 21 to adhere to the light guide plate 20, making it impossible for technicians to effectively open the door panel 2 using the handle 21, thus preventing technicians from being injured by static electricity inside the mobile cabinet 1.

[0063] It should be noted that photovoltaic power generation equipment typically outputs electrical energy with low voltage and high current. After being boosted by the boost module 10, it becomes electrical energy with high voltage and low current. However, during operation, the boost module 10 can generate static electricity in the mobile cabinet 1, posing a risk of electric sparks. The handle 21, coil 18, and iron core 23 effectively prevent electrostatic discharge from injuring technicians. After being boosted by the boost module 10, the electrical energy becomes high-voltage, low-current energy. This energy then passes through a resistor and an electrostatic generator 11 connected in parallel with the resistor. This process not only dissipates static electricity inside the mobile cabinet 1 but also removes dust from the interior of the cabinet, reducing dust accumulation on the electrical components and preventing reduced heat dissipation efficiency.

[0064] During the process of transmitting the electrical energy generated by the photovoltaic power generation equipment to the storage battery 8 for energy storage, the connecting wires of the electrical components, the boost module 10, and the storage battery 8 will all generate heat. In addition, the coil 18 and the iron core 23 generate electromagnetic induction. Therefore, the heat of the coil 18 will be slightly higher than that of the other wires. By monitoring the heat generated by the coil 18 during power transmission, the heat of the connecting wires between the electrical components inside the mobile cabinet 1 can be effectively monitored. In this way, by monitoring the heat of the coil 18, the purpose of monitoring the connecting wires between the electrical components inside the mobile cabinet 1 can be achieved. This helps to avoid the risk of short circuit accidents caused by the heat generated by the wires during power transmission burning the wire sheath. On the one hand, it can extend the service life of the device, and on the other hand, it can effectively reduce the risk of short circuit accidents.

[0065] During the heating process of the connecting wires of electrical components, the boost module 10, and the battery 8, the cooling fan 25 and the evaporator 7 are turned on to cool the surrounding air. During the cooling process, the evaporator 7 also condenses the water vapor in the air into water droplets. On the one hand, this reduces the water vapor content in the air and prevents short circuits caused by excessive moisture inside the mobile cabinet 1. On the other hand, it also prevents the metal components inside the mobile cabinet 1 from rusting due to excessive moisture.

[0066] When the cooling fan 25 is turned on, it blows air into the mobile cabinet 1, effectively circulating the air inside and controlling the temperature of the various components within the cabinet. It also effectively dissipates heat from the connecting wires of the electrical components, the boost module 10, and the battery 8. During operation, the cooling fan 25 blows air cooled by the evaporator 7 into the mobile cabinet 1, further cooling the connecting wires of the electrical components, the boost module 10, and the battery 8.

[0067] During the heat generation process of coil 18, the heat is conducted to the thermistor 29, causing its temperature to rise. The resistance of thermistor 29 decreases as the temperature increases. In the circuit, when the resistance of thermistor 29 decreases, the current in the circuit increases. Increased current leads to increased output power of the electrical components in the circuit. Therefore, when the resistance of thermistor 29 decreases, the output power of bulb 17 and cooling fan 25 increases. With increased power, cooling fan 25 blows out more air, further effectively dissipating heat from the interior of the mobile cabinet 1, preventing overheating of the electrical components and battery 8 inside the mobile cabinet 1. This further improves the safety of battery 8 during charging and discharging.

[0068] As the output power of bulb 17 increases, the color of its light changes, and the light emitted by bulb 17 is evenly dispersed on light guide plate 20. This allows technicians to easily distinguish the light, avoiding the situation where the light is indistinct and the color cannot be effectively observed during the day due to sunlight. Furthermore, the change in light color allows technicians to effectively judge the temperature of the wires in the mobile cabinet 1. When the temperature is too high, technicians can determine whether to disconnect the input electromagnetic switch 9, thus preventing damage to the electrical components inside the mobile cabinet 1 due to overheating. This also improves safety and helps prevent short circuits caused by overheating. The light guide plate 20 effectively disperses the light and allows technicians to observe the interior of the mobile cabinet 1. Since the light guide plate 20 is made of resin, it is not magnetically attracted when the iron core 23 generates magnetism.

[0069] After the energy storage ends, the circuit is de-energized by disconnecting the input electromagnetic switch 9. At this time, no current flows inside the coil 18, so the magnetic force of the iron core 23 will also disappear, which will cause the fixed magnet 30 to no longer be tightly attached to the light guide plate 20, allowing technicians to open the door panel 2 through the handle 21.

[0070] After the energy storage is completed, the device is moved by the casters 6 at the bottom of the cabinet 1. Before that, the circuit of the coil 18 and the thermistor 29 can be connected in series by the two adjusting electromagnetic switches 19, so that the iron core 23 generates magnetic force to effectively close the door panel 2.

[0071] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
