Description

Technical Field

[0001] This utility model relates to the field of energy storage power station technology, and more specifically, to a safety protection device for an energy storage power station. Background Technology

[0002] An energy storage power station is a facility that converts electrical energy into other forms of energy for storage, to prepare for unforeseen circumstances. Here are some key points about energy storage power stations: Energy storage power stations store excess electrical energy during off-peak hours and release it into the grid during peak hours, alleviating grid pressure, balancing power supply and demand, and improving grid stability and reliability. For example, when electricity demand is low at night, energy storage power stations can store excess electrical energy and release it during peak daytime hours, thus reducing grid pressure during peak periods and preventing power outages due to insufficient power.

[0003] The prior art discloses a fire extinguishing nozzle protection device for an energy storage power station, with application number CN202411492374.X. This device is related to the field of power supply energy storage power stations and provides protection for the fire extinguishing nozzles of the energy storage power station.

[0004] Although the aforementioned utility model can protect the fire extinguishing nozzle, it does not have a corresponding quick-release device. This means that in the event of a fire, the protective cover needs to be manually opened and disassembled by staff, which takes time and may cause them to miss the golden moisture for fire fighting, leading to a rapid spread of the fire and threatening life and property safety. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a safety protection device for energy storage power stations, which has the advantage of automatically opening the protective cover, thereby solving the problems mentioned in the background technology.

[0007] (II) Technical Solution

[0008] To achieve the aforementioned advantages of automatically opening the protective cover, the specific technical solution adopted by this utility model is as follows: A safety protection device for an energy storage power station includes a mounting plate. A U-shaped frame is welded to the lower surface of the mounting plate. A fire extinguishing nozzle is installed through the lower surface of the U-shaped frame. An annular piezoelectric vibrating plate is glued to the lower surface of the U-shaped frame. An electromagnet is glued to the lower surface of the annular piezoelectric vibrating plate. An iron core is provided inside the electromagnet, and a coil is wound around the surface of the iron core. A magnetic ring is provided below the electromagnet. The magnetic ring is fixed in a groove opened on the upper surface of a fixing ring. A filter screen is provided on the lower surface of the fixing ring, and a filter cloth is provided on the outer side of the filter screen.

[0009] Furthermore, the lower surface of the shaped frame is provided with microelectrodes.

[0010] Furthermore, the filter cloth is made of electret nonwoven fabric.

[0011] Furthermore, the outer surface of the filter screen is welded with raised strips, and multiple raised strips are distributed in a ring array on the lower surface of the filter screen, and the edge of the filter cloth is bonded to the raised strips with glue.

[0012] Furthermore, the surface of the filter cloth is coated with a superhydrophobic nano-coating.

[0013] Furthermore, it also includes a control module, which is electrically connected to the annular piezoelectric vibrating plate, the electromagnet, and the microelectrode, and the control module has a built-in dust concentration sensor.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a safety protection device for an energy storage power station, which has the following beneficial effects:

[0016] (1) In this utility model, the electromagnet and the magnetic ring are fixed to the protective structure (filter screen, filter cloth) by magnetic attraction. When a fire signal is detected (such as a sudden rise in temperature or excessive smoke concentration), the current of the electromagnet coil can be cut off immediately, the magnetic ring loses magnetic attraction, the protective structure falls off quickly, and the fire extinguishing nozzle sprays the extinguishing agent directly without obstruction. The response time can be shortened to less than 0.5 seconds. Compared with the traditional method of manually opening the protective cover, the efficiency of handling the initial stage of the fire is greatly improved.

[0017] (2) This utility model is equipped with an annular piezoelectric vibrating plate and a micro electrode. When the dust concentration exceeds the threshold, the micro electrode is activated to release ions with opposite polarity to the dust, neutralize the surface charge of the dust, and eliminate electrostatic adsorption. Under the action of the piezoelectric vibrating plate, the filter screen is made to vibrate at high frequency, which vibrates the dust on the surface of the filter cloth, thereby removing the accumulated dust and cleaning it regularly. This avoids the corrosion and wear caused by the accumulation of dust on the protective structure, thus extending the service life of the protective structure and reducing the replacement cost.

[0025] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0026] According to an embodiment of the present invention, a safety protection device for an energy storage power station is provided.

[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4 As shown, a safety protection device for an energy storage power station according to an embodiment of the present invention includes a mounting plate 1. A U-shaped frame 2 is welded to the lower surface of the mounting plate 1. A fire extinguishing nozzle 3 is installed through the lower surface of the U-shaped frame 2. An annular piezoelectric vibrating plate 4 is glued to the lower surface of the U-shaped frame 2. An electromagnet 5 is glued to the lower surface of the annular piezoelectric vibrating plate 4. An iron core 6 is provided inside the electromagnet 5, and a coil 7 is wound around the surface of the iron core 6. A magnetic ring 8 is provided below the electromagnet 5. The magnetic ring 8 is fixed in a groove opened on the upper surface of a fixing ring 9. A filter screen 10 is provided on the lower surface of the fixing ring 9, and a filter cloth 12 is provided on the outer side of the filter screen 10.

[0028] In one embodiment, the electromagnet 5 and the magnetic ring 8 are magnetically attracted to fix the protective structure (filter screen 10, filter cloth 12). When a fire signal is detected (such as a sudden rise in temperature or excessive smoke concentration), the current of the electromagnet 5 coil 7 can be cut off immediately, the magnetic ring 8 loses its magnetic attraction, the protective structure falls off quickly, and the fire extinguishing nozzle 3 sprays the extinguishing agent directly without obstruction. The response time can be shortened to less than 0.5 seconds. Compared with the traditional method of manually opening the protective cover, the efficiency of handling the initial stage of a fire is greatly improved.

[0029] Specifically, the lower surface of the U-shaped frame 2 is provided with microelectrodes 13, and the filter cloth 12 is made of electret nonwoven fabric.

[0030] In one embodiment, when the dust concentration exceeds a threshold, the microelectrode 13 is activated to release ions with opposite polarity to the dust, neutralizing the surface charge of the dust and eliminating electrostatic adsorption. Under the action of the piezoelectric vibrating plate, the filter screen 10 is caused to generate high-frequency vibration, which vibrates the dust on the surface of the filter cloth 12, thereby removing the accumulated dust and achieving the purpose of regular cleaning. This avoids the corrosion and wear caused by dust accumulation on the protective structure, thereby extending the service life of the protective structure and reducing replacement costs.

[0031] Specifically, the outer side of the filter screen 10 is welded with raised strips 11, and multiple raised strips 11 are distributed in a ring array on the lower surface of the filter screen 10, and the edge of the filter cloth 12 is bonded to the raised strips 11 with glue.

[0032] In one embodiment, multiple protrusions 11 are welded in a ring array to the lower surface of the filter screen 10 to form a radial support structure similar to "umbrella ribs," providing rigid support for the filter cloth 12.

[0033] Specifically, the surface of filter cloth 12 is coated with a superhydrophobic nano-coating.

[0034] In one embodiment, the adhesion between dust and filter cloth 12 is reduced.

[0035] Specifically, it also includes a control module, which is electrically connected to the annular piezoelectric vibrating plate 4, the electromagnet 5, and the microelectrode 13, and has a built-in dust concentration sensor.

[0036] In one embodiment, the control module (not shown in the figure) integrates functions such as dust monitoring, electromagnetic control, and vibration cleaning. It can be connected to the BMS of the energy storage power station via RS485 interface to upload device status data in real time, thereby achieving unattended operation and maintenance.

[0037] Working principle: When a fire signal is detected (such as a sudden rise in temperature or excessive smoke concentration), the current to the electromagnet 5 coil 7 can be cut off immediately, the magnetic ring 8 loses its magnetic attraction, the protective structure quickly falls off, and the fire extinguishing nozzle 3 sprays the extinguishing agent directly without obstruction. The response time can be shortened to less than 0.5 seconds. Compared with the traditional method of manually opening the protective cover, the efficiency of the initial fire response is greatly improved. When the dust concentration exceeds the threshold, the micro electrode 13 is activated to release ions with opposite polarity to the dust, neutralize the surface charge of the dust, and eliminate electrostatic adsorption. Under the action of the piezoelectric vibrating plate, the filter screen 10 is caused to generate high-frequency vibration, which vibrates the dust on the surface of the filter cloth 12, thereby removing the accumulated dust and achieving the purpose of regular cleaning. This avoids the corrosion and wear caused by the accumulation of dust to the protective structure, thereby extending the service life of the protective structure and reducing replacement costs.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
