Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution:

[0022] Example 1

[0023] The problems to be solved are as follows: existing humidifier control cabinet systems have low thermal efficiency and high heat conduction loss. In addition, existing isothermal humidifiers on the market have two types: electrode and resistor. Both types have scaling problems, requiring the replacement of electrodes and heating rods.

[0024] The solution is as follows: An energy storage device for photovoltaic power generation includes a device body 1. The device body 1 includes a base 2, a humidifying cylinder 3, a water replenishment pump 4, a humidifier control cabinet 5, a PLC 6, and a steam output device 7. The humidifying cylinder 3 is fixed to the top of the base 2. The water replenishment pump 4 and the humidifier control cabinet 5 are both located on the right side of the humidifying cylinder 3. The steam output device 7 is bolted to the top of the humidifying cylinder 3. The PLC is installed inside the humidifier control cabinet 5. The humidifying cylinder 3 includes an outer humidifying cylinder 9, an inner humidifying cylinder 10, and an electromagnetic coil. 11. The humidifying inner cylinder 10 is located inside the humidifying outer cylinder 9. Several sets of connecting bolts 12 are fixed between the humidifying outer cylinder 9 and the humidifying inner cylinder 10. An outer cavity 13 is provided between the inner wall of the humidifying outer cylinder 9 and the outer wall of the humidifying inner cylinder 10. An inner cavity 14 is provided inside the humidifying inner cylinder 10. The top and bottom of the humidifying inner cylinder 10 are through-type structures. The electromagnetic coil 11 is sleeved on the outer wall of the humidifying outer cylinder 9. The electromagnetic coil 11 is connected to the humidifier control cabinet 5 through a connecting wire. The humidifier control cabinet 5 is connected to the PLC 6 through a connecting wire.

[0025] Analysis of the above: PLC6 controls the humidifier control cabinet 5 via a connecting cable, causing the electromagnetic coil 11, which is fitted onto the outer wall of the humidifier outer cylinder 9, to carry a high-frequency alternating current. Based on Faraday's law of electromagnetic induction, an alternating magnetic field is generated. This magnetic field cuts through the magnetically conductive humidifier outer cylinder 9, causing eddy currents and heating. The humidifier outer cylinder 9 and the humidifier inner cylinder 10 are fixed together by a connecting bolt 12. The water in the outer cavity 13 between them decreases in density after being heated by the outer cylinder wall, creating a chimney effect that causes it to rise and flash. The unevaporated cold water flows back from the inner cavity 14 of the through-type humidifier inner cylinder 10 to the bottom, and then re-enters the outer cavity 13 for recirculation and heating. The water replenishment pump 4 replenishes water to the humidifier cylinder 3, and the steam is finally discharged through the steam output device 7 at the top. When the humidification volume needs to be adjusted, PLC6 controls the frequency converter output of the humidifier control cabinet 5 to change the current intensity of the electromagnetic coil 11 to adjust the heating power; when the water level in the outer cavity 13 is too low, PLC triggers the water replenishment booster pump 4 to increase the water replenishment volume, and when the water level is too high, the water replenishment volume is reduced; if it is necessary to inspect the inside of the humidifier cylinder 3, the connecting bolt 12 can be disassembled to separate the inner and outer cylinders; the electromagnetic coil 11 has a non-contact heating design to avoid heat conduction loss, and the thermal efficiency is up to 98.3% (data from the document); the inner and outer cylinders have dual cavities (outer cavity 13, inner cavity 14) for circulation and guidance to prevent local overheating and reduce scaling; the PLC fully automatic control reduces manual intervention and, together with frequency conversion technology, achieves high-precision humidification adjustment.

[0026] Example 2:

[0027] Please see Figure 1-4 Based on Embodiment 1, this utility model provides a technical solution: the bottom of the humidifying outer cylinder 9 is provided with a fixing ring 15, the top outer side of the humidifying outer cylinder 9 is provided with an upper flange 16, the bottom right side of the humidifying outer cylinder 9 is provided with an input pipe 17, and the input end of the input pipe 17 is connected to the output end of the water replenishment booster pump 4.

[0028] Analysis of the above: The fixing ring 15 at the bottom of the humidifying outer cylinder 9 cooperates with the base 2 to ensure that the humidifying outer cylinder 9 is installed stably and vertically; the upper flange 16 on the outer side of the top provides a bolt installation interface for the steam output device 7 to achieve a sealed connection; one end of the input pipe 17 at the bottom right side is connected to the output end of the water replenishment pump 4, and the other end is connected to the humidifying outer cylinder 9 to deliver pressurized pure water to the outer cavity 13 to meet the water volume requirements for circulating heating; during the equipment installation stage, the verticality of the humidifying outer cylinder 9 is calibrated by the fixing ring 15 to avoid tilting and affecting water circulation; when replacing or repairing the steam output device 7, it can be separated by removing the bolts at the upper flange 16.

[0029] Example 3:

[0030] Please see Figure 1-4This utility model provides a technical solution based on Embodiment 1: A steel wire water blocking device 8 is provided above the interior of the humidifying outer cylinder 9. The steel wire water blocking device 8 is located above the humidifying inner cylinder 10. The steel wire water blocking device 8 includes an installation ring 18, a cross steel bar 19, and a water blocking steel wire mesh 20. The installation ring 18 is fixed to the inner wall of the humidifying outer cylinder 9 by welding. The cross steel bar 19 is welded inside the installation ring 18. The water blocking steel wire mesh 20 is installed inside the cross steel bar 19.

[0031] Analysis of the above: The steel wire water-blocking device 8 is welded and fixed to the inner wall of the humidifying outer cylinder 9 via the mounting ring 18, located above the humidifying inner cylinder 10; the cross steel bar 19 is welded inside the mounting ring 18 to provide support for the water-blocking steel wire mesh 20; when the wet steam generated by flash evaporation in the outer cavity 13 rises, the water-blocking steel wire mesh 20 intercepts the tiny liquid water droplets within it, and the water droplets fall back to the water surface inside the humidifying cylinder 3 under gravity, re-entering the circulation, thus realizing the conversion of wet steam into dry steam; after long-term use, if an increase in the amount of water carried by the steam is detected (decreased humidification accuracy), it can... Remove the upper flange 16, take out the water-blocking steel wire device 8, and clean the impurities attached to the surface of the water-blocking steel wire mesh 20. If the water-blocking steel wire mesh 20 is damaged, simply replace it with a new mesh; there is no need to replace the entire device. The water-blocking steel wire mesh 20 effectively removes liquid water from the steam, ensuring the output of dry steam and helping the constant temperature and humidity unit achieve a humidity accuracy of ±2% (file data). The mounting ring 18 and the cross steel bar 19 have a stable structure, making the device easy to install and remove, and reducing maintenance costs. It also prevents water droplets from carrying impurities and adhering to subsequent components, further reducing the risk of overall scaling.

[0032] Example 4:

[0033] Please see Figure 1-4 Based on Embodiment 1, this utility model provides a technical solution: the steam output device 7 includes a flange cover 21, a first discharge pipe 22 and a second discharge pipe 23. The flange cover 21 is fixed to the top of the upper flange 16 by bolts, and the first discharge pipe 22 and the second discharge pipe 23 are both installed on the top of the upper flange 16.

[0034] Analysis of the above: The flange cover 21 of the steam output device 7 is fixed to the top of the upper flange 16 with bolts, achieving a seal on the top of the humidifying outer cylinder 9 and preventing steam leakage; the dry steam after being demisted by the steel wire gathers on the top of the humidifying outer cylinder 9, part of which is discharged naturally through the first discharge pipe 22, and the other part is discharged from the top of the second discharge pipe 23; if the steam pressure inside the humidifying outer cylinder 9 is detected to be too high, the flange cover 21 can be disassembled in an emergency to release the pressure, or the first and second discharge pipes can be checked for blockage; the dual discharge pipe design adapts to different steam demand scenarios and is highly flexible; the flange cover 21 has reliable sealing performance, avoiding energy loss caused by steam leakage, and is also convenient for emergency maintenance.

[0035] Working principle: First, the water replenishment pump 4 delivers water to the humidifier cylinder 3 fixed on the base 2 through the input pipe 17, filling the outer cavity 13 formed by the connecting bolt 12 between the outer humidifier cylinder 9 and the inner humidifier cylinder 10. Next, the PLC 6 controls the humidifier control cabinet 5, causing the electromagnetic coil 11 sleeved on the outer wall of the outer humidifier cylinder 9 to pass a high-frequency alternating current. The generated alternating magnetic field cuts the magnetically conductive outer humidifier cylinder 9, causing it to heat up rapidly through eddy current collisions, thereby heating the water in the outer cavity 13 to boiling and producing steam. During the heating process, the hot water with reduced density in the outer cavity 13 rises due to the "chimney effect," and after flash evaporation, it separates into wet steam and unevaporated cold water. The unevaporated cold water flows from the top to the bottom of the humidifier cylinder, which has a continuous structure. The humidified steam flows back to the bottom of the humidifying outer cylinder 9 from the inner cavity 14 of the inner cylinder 10 and re-enters the outer cavity 13 for recirculation and heating. The humidified steam continues to rise and passes through the water-blocking device 8, which consists of an installation ring 18, a cross steel bar 19, and a water-blocking steel wire mesh 20, located above the inner cavity of the humidifying outer cylinder 9. The tiny liquid water droplets carried in the steam are intercepted by the water-blocking steel wire mesh 20 and fall back to the water surface. The dry steam after the water droplets are removed enters the steam output device 7 at the top. Part of it is discharged naturally through the first discharge pipe 22, and the other part is discharged through the second discharge pipe 23. Finally, it provides a humidification effect with a humidity accuracy of ±2% for the constant temperature and humidity unit. The thermal efficiency of the whole process is up to 98.3%. At the same time, the safety protection function integrated into the PLC6 ensures the stable operation of the equipment.
