Description

Technical Field

[0001] This utility model relates to the field of energy storage converter technology, and in particular to an energy storage converter with a filter and dustproof structure. Background Technology

[0002] ① Early energy storage converters generally adopted an open heat dissipation structure, relying on exhaust fans to directly draw in external air and force it through the equipment for forced convection cooling. The external airflow entered the core area of ​​the equipment without any pretreatment, and impurities such as suspended dust particles and plant fibers in the air were adsorbed onto the surfaces of circuit boards, capacitor banks, and heat sink fins. After long-term operation, these impurities deposited to form a coating layer, which not only hindered the heat exchange efficiency between the heat-generating components and the air, leading to abnormally high device temperatures, but more seriously, the accumulation of conductive dust between high-voltage terminals could induce partial discharge or short-circuit faults, significantly increasing the risk of unexpected equipment shutdowns and the frequency of hardware maintenance.

[0003] ② To mitigate dust intrusion, some improvements include adding a densely woven mesh filter structure to the air inlet. This structure intercepts suspended solids in the airflow through the gaps between the fiber layers. Its physical barrier effectively captures larger particles of debris and flying insects, allowing pre-purified air to enter the equipment. This method significantly reduces dust accumulation inside the equipment during initial operation, and the filter can be disassembled and washed for repeated use.

[0004] ③ However, mechanical filters reveal fundamental flaws in long-term operation: the intercepted fine dust continuously embeds itself deep within the filter fibers, gradually forming hardened grime. This hardening process leads to two irreconcilable contradictions—first, grime blockage causes a precipitous drop in filter permeability, requiring the exhaust fan to continuously increase its power to maintain airflow, accelerating fan aging and increasing energy consumption; second, repeated disassembly and cleaning cause fatigue and damage to the filter structure, drastically shortening the replacement cycle, while the maintenance operation itself may cause the hardened dust to detach and fall into the equipment. The technical crux lies in the fact that a single physical filtration system bears the entire dust removal load, creating a conflict between dust removal efficiency and maintenance costs. Utility Model Content

[0005] The purpose of this utility model is to provide an energy storage converter with a dustproof filter structure, which solves the systemic problem caused by the deep blockage of the filter screen when the traditional energy storage converter uses a physical filter screen to filter the dust load by intercepting all the dust load.

[0006] To achieve the above objectives, this utility model provides an energy storage converter with a dustproof and filtering structure, including a frame plate. A connecting frame is snapped onto one side of the opening of the frame plate, and a barrier net is fixedly installed inside the connecting frame. Electrostatic fins are fixedly installed inside the frame plate and extend into the filter box. The filter box is fixedly installed on the side opposite to the frame plate and the connecting frame. The filter box and the frame plate are interconnected, and a slot is provided at its top. An outer protective frame is inserted into the slot. The top of the outer protective frame has a groove, and a corrugated filter element is fixedly installed inside the outer protective frame. A wire groove is provided on one side of the filter box, and a flexible wire passes through the wire groove. One end of the flexible wire is connected to the electrostatic fins, and the other end of the flexible wire is connected to the output terminal of an electrostatic generator. The power terminal of the electrostatic generator is connected to the converter body through a connecting wire.

[0007] The converter body has two symmetrically installed doors on one side via hinges. Each door extends downwards from its center point and is fitted with a frame plate by bolts, so that the filter box faces the interior of the converter body.

[0008] The converter body is provided with heat dissipation slots on the upper sides of the two sides away from the door. An exhaust fan is installed in the heat dissipation slot by a bracket. A metal mesh plate is installed at the opening of the heat dissipation slot by bolts.

[0009] The converter body has wiring holes on both sides of the same plane as the heat dissipation groove, and two sets of corner plates are installed on the bottom of both sides of the converter body and on the same plane as the heat dissipation groove by bolts.

[0010] The corner plates are respectively bolted to the top of the support frame on the side away from the converter body, and two connecting crossbars are respectively bolted between the support frames.

[0011] The bottom of the support frame is embedded with shock-absorbing pads. The support frame and the shock-absorbing pads are provided with multiple fixing holes along the vertical direction. The fixing holes are coaxial and can be fixed by bolts.

[0012] This utility model discloses an energy storage converter with a dustproof and filtering structure. It achieves efficient dust control by constructing a multi-stage collaborative filtration mechanism in the air intake channel of the converter body. In the specific structure, the connecting frame with the opening side of the frame plate has a built-in barrier net to block large foreign objects such as leaves. The electrostatic fins extending from the inside of the frame plate to the filter box are connected to the electrostatic generator through flexible wires. The electrostatic field generated by the power of the converter body is used to actively adsorb fine dust in the airflow. The outer protective frame is inserted into the slot at the top of the filter box, which is connected to the frame plate. The groove at the top of the outer protective frame provides a manual lifting operation point. The pleated filter element inside the frame unfolds the pleated filter surface to intercept the residual particles after electrostatic adsorption. The airflow sequentially passes through a three-stage treatment process: coarse filtration via a barrier mesh, active capture by electrostatic fins, and fine filtration via a pleated filter element. Electrostatic adsorption significantly reduces the dust load on the pleated filter element. The outer frame, through a plug-in installation combined with a top-mounted groove structure, enables tool-free vertical pull-out filter element maintenance. This structure maintains unobstructed airflow while resolving the inherent contradiction of traditional single-stage filtration: the electrostatic unit undertakes the main dust removal task, preventing deep clogging of the filter element, while the mechanical cooperation between the slot and the groove simplifies filter element replacement, fundamentally resolving the conflict between dust-proof efficiency and maintenance convenience.

Detailed Implementation

[0020] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0021] Please see Figures 1-5 .

[0022] This utility model provides an energy storage converter with a dustproof filter structure, including a frame plate 101 installed on the side doors 115 of the converter body 114. A connecting frame 102 is installed at the opening of the frame plate 101 through a snap-fit ​​structure to enable detachable maintenance. A barrier net 103 fixedly installed inside the connecting frame 102 serves as a primary filter barrier to intercept large foreign objects such as leaves. Electrostatic fins 104 extending from inside the frame plate 101 into the filter box 105 capture fine dust through electrostatic adsorption. The filter box 105 is fixed between the frame plate 101 and the connecting frame 102 to form a filter box 105. A sealed cavity guides airflow; a slot 107 is provided on the top of the filter box 105, which is connected to the frame plate 101, for inserting the outer protective frame 108. A pull groove 109 provided on the top of the outer protective frame 108 provides a manual force point so that the outer protective frame 108 can be vertically pulled out for maintenance without tools. The pleated filter element 110 fixed inside the outer protective frame 108 uses the pleated structure to expand the filtration area to achieve deep dust interception; a flexible wire 112 is run through the wire groove 111 on the outside of the filter box 105 to connect the electrostatic fins 104 to the output terminal of the electrostatic generator 113. The electrostatic generator 113 is connected to... A power supply line is connected to the converter body 114 to provide a stable electrostatic field; two hinged, symmetrically mounted cabinet doors 115 on both sides of the converter body 114 support the frame plate 101 and the filter box 105 assembly, with the air inlet of the filter box 105 facing the interior of the converter body 114; exhaust fans 117, fixed by brackets, force airflow circulation within the heat dissipation slots 116 on the upper sides of the converter body 114; bolted metal mesh plates 118 at the openings of the heat dissipation slots 116 prevent backflow of external foreign objects; wiring holes are located on both sides of the converter body 114 at the same plane as the heat dissipation slots 116. 119 is used for external cable insertion, and two sets of corner plates 120, which are bolted to the bottom, serve as connection points for the support structure. The side of the corner plate 120 away from the converter body 114 is fixed to the top of the support frame 121 by bolts to distribute the equipment load. Two connecting crossbars 122 are connected laterally to the two sides of the support frame 121 by bolts to enhance the overall rigidity. The shock-absorbing pads 123 embedded at the bottom of the support frame 121 absorb the vibration of the equipment operation to protect the internal components. Multiple fixing holes 124 coaxially arranged on the support frame 121 and the shock-absorbing pads 123 achieve shock-absorbing fixation between the equipment and the foundation by through bolts.

[0023] Working principle: When the converter body 114 operates, it generates heat. The exhaust fans 117, installed in the heat dissipation slots 116 on both sides of the converter body 114, start working, actively drawing external airflow into the equipment. The airflow first enters through the filter box 105 inlet located at the converter enclosure door 115. The barrier net 103 at the inlet acts as the first line of defense, intercepting large foreign objects such as leaves and flying insects, preventing them from entering the equipment and initially ensuring smooth airflow. The airflow then enters the filter box 105, where the electrostatic generator 113, powered by the converter body 114, starts working. The generated static charge is transferred to the extended... The airflow is charged onto the electrostatic fins 104 inside the filter box 105, utilizing electrostatic force to efficiently adsorb fine dust and particulate matter carried in the airflow, significantly improving dust removal efficiency and reducing the clogging of physical filter media. After initial adsorption by the electrostatic fins 104, any remaining fine dust particles that may not have been completely captured by electrostatics continue to flow forward and enter the pleated filter element 110 installed inside the filter box 105. The pleated filter element 110, through its special pleated structure, provides a large filtration surface area, deeply intercepting and filtering residual fine dust, forming a secondary physical filtration barrier to ensure that the air entering the converter is fully purified. When the filter element needs to be removed due to long-term use... During replacement, the operator can directly apply force through the pull groove 109 at the top of the outer protective frame 108 to vertically pull out the entire outer protective frame 108, which is inserted into the slot 107 at the top of the filter box 105, along with the internally fixed pleated filter element 110. This allows for quick filter element maintenance without the need for tools, significantly improving replacement convenience. The filtered clean air then flows from the bottom of the filter box 105 into the converter body 114, flowing upwards. As it passes through the heating elements inside the converter, it effectively carries away the heat generated. Finally, the airflow carrying heat is guided to the heat dissipation slots 116 on both sides of the converter body 114 and powerfully exhausted by the exhaust fan 117. The external cooling system completes the heat dissipation cycle. During the airflow discharge process, the metal mesh plate 118 installed at the opening of the heat dissipation trough 116 acts as a physical barrier, further preventing external leaves or other foreign objects from backflowing or accidentally entering the equipment through the heat dissipation trough 116. In addition, the entire equipment is mounted on the foundation via the support frame 121. The shock-absorbing pads 123 embedded at the bottom of the support frame 121 can effectively absorb vibrations transmitted from the equipment during operation or from the outside, preventing damage to internal precision components and improving the stability of equipment operation. The coaxial fixing holes 124 on the support frame 121 and the shock-absorbing pads 123 are fixed by bolts, ensuring the overall equipment is firmly installed in a shock-absorbing state.

Those skilled in the art can understand that implementing all or part of the above embodiments and making equivalent changes in accordance with the claims of this application still fall within the scope of this application.
