Description

Technical Field

[0001] This application relates to the field of converter cabinet technology, specifically an energy storage converter cabinet. Background Technology

[0002] As a key piece of equipment, the energy storage converter cabinet plays an important role in the conversion and storage of electrical energy. It can flexibly convert electrical energy between AC and DC, and efficiently store and release electrical energy in the energy storage system. Whether in the scenarios of new energy grid connection, grid peak shaving, or emergency power supply, the energy storage converter cabinet plays an indispensable role.

[0003] For example, patent CN222763395U discloses an energy storage converter cabinet, including components such as a cabinet body, mounting frame, filter compartment, connecting holes, fan, and fixing holes. The beneficial effect of this utility model is that it can clean the dust on one side of the filter frame, preventing dust from clogging the filter frame and affecting airflow, thus preventing any impact on the cabinet's heat dissipation. It eliminates manual labor and, while cleaning itself, also discharges dust into the filter compartment and the side cabinet, making the overall design quite practical.

[0004] However, in the energy storage converter cabinet of the aforementioned patent, the brush roller used for cleaning dust in the filter component will accumulate a certain amount of dust during long-term use, and this dust is easy to accumulate in the gaps between the brush fibers. As the usage time increases, the accumulated dust will reduce the cleaning effect of the brush roller on the filter screen, and may even cause secondary pollution to the filter screen due to the dust carried by the brush roller itself, resulting in a decrease in filtration efficiency. Therefore, it is necessary to provide an energy storage converter cabinet to solve the above problems. Utility Model Content

[0005] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide an energy storage converter cabinet that solves the problem that the brush roller of the filter component in the above patent suffers from reduced cleaning effect, secondary pollution of the filter screen and reduced filtration efficiency after long-term use due to the accumulation of dust.

[0006] The technical solution adopted by this application to solve its technical problem is: an energy storage converter cabinet, comprising:

[0007] Converter cabinet;

[0008] A suction assembly is installed on the converter cabinet. The suction assembly includes a suction box installed on the converter cabinet, and a suction device is installed on the suction box.

A filter screen is installed inside the filter frame.

[0010] A drive assembly is mounted on the filter frame. The drive assembly includes an intermediate plate mounted on the filter frame, a plurality of vibration seats mounted on the intermediate plate, and a rotating rod driven by power on the suction box. A cam adapted to the vibration seats is mounted on the rotating rod.

[0011] Furthermore, one end of the rotating rod extends outside the suction box and is equipped with a first bevel gear;

[0012] A drive motor is installed on one side of the converter cabinet, and a second bevel gear adapted to the first bevel gear is installed on the output shaft of the drive motor.

[0017] Furthermore, a dust guide plate is installed inside the collection box, and the lower end of the dust guide plate extends to the top of the drawer.

[0018] The beneficial effects of this application are as follows: The energy storage converter cabinet provided by this application, through the arrangement of a suction component, a filter component, and a drive component, allows the suction component's suction fan to draw in external air, which is then guided to the filter component via the suction box.

Detailed Implementation

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0033] like Figure 1 As shown, this application provides an energy storage converter cabinet, including a converter cabinet body 1, which is the carrier of the entire energy storage converter cabinet. Various electrical components for power conversion and storage are installed inside the cabinet body, which are existing technologies, including converters, controllers, etc. An air inlet rectangular hole 11 is provided on one side inside the converter cabinet body 1. The air inlet rectangular hole 11 serves as a channel for air to enter the converter cabinet body 1. Two sets of exhaust windows 12 are provided on the other side of the converter cabinet body 1. The exhaust windows 12 are used to exhaust the gas inside the converter cabinet body 1 to the outside.

[0034] A protective door 13 is hinged to the front of the converter cabinet 1. The edge of the protective door 13 is equipped with a sealing strip (not shown in the figure), which enhances the sealing performance of the converter cabinet 1 and can effectively prevent dust and moisture from entering the interior of the converter cabinet 1, providing a cleaner and drier operating environment for the internal components.

[0035] like Figure 2 As shown, a suction assembly 2 is installed on the converter cabinet 1. The suction assembly 2 is used to draw external air into the converter cabinet 1. The suction assembly 2 includes a suction box 21 that is bolted to the converter cabinet 1. The suction box 21 is made of aluminum alloy profiles, which is lightweight and has good heat dissipation performance. A suction fan 22 is bolted to the upper and lower ends of the suction box 21, respectively. The suction fan 22 is an axial flow fan and is electrically connected to the controller of the converter cabinet 1. Its air volume and air pressure can provide sufficient cooling air for the inside of the converter cabinet 1.

[0036] like Figure 3 , Figure 4 and Figure 6 As shown, a filter assembly 3 is installed inside the air intake box 21. The filter assembly 3 filters and purifies the intake air, and at the same time, the drive part realizes its own vibration cleaning function to ensure that the air entering the converter cabinet 1 is clean and maintain a good operating environment for the equipment. The filter assembly 3 includes an assembly box 31 that is fixedly installed on the upper and lower parts of the air intake box 21 respectively. The assembly box 31 is a rectangular cavity structure used to install the other parts of the filter assembly 3.

[0037] Multiple sets of springs 32 are installed at intervals inside the assembly box 31. The springs 32 are made of spring steel and have stable elastic properties. At one end of each spring 32, a middle block 33 that can slide horizontally within the assembly box 31 is fixedly installed by welding. The middle block 33 is made of wear-resistant cast iron, and friction-reducing components are installed at the contact parts with the inner wall of the assembly box 31 to reduce friction. At the end of the middle block 33 away from the spring 32, a filter frame 34 is fixedly installed by bolts. The filter frame 34 is an aluminum alloy frame structure. Inside the filter frame 34, a filter screen 35 is installed by stainless steel bolts. The filter screen 35 is existing technology and adopts a three-layer composite structure (outer layer primary nylon mesh + middle layer activated carbon filter + inner layer high-efficiency HEPA filter), which can effectively filter particulate matter in the air.

[0038] The upper and lower ends of the suction box 21 are respectively provided with assembly grooves 311 that are adapted to the assembly box 31. The two sides of the suction box 21 are respectively provided with guide grooves 341 that are adapted to the filter frame 34. The two sides of the filter frame 34 are embedded in the guide grooves 341, which not only provides vibration guidance for the filter frame 34, but also prevents it from shifting when vibrating.

[0039] like Figures 3-5 As shown, a drive assembly 4 is installed on the filter frame 34. The drive assembly 4 is a power transmission mechanism that realizes the self-cleaning function of the filter assembly 3. It drives the filter frame 34 to vibrate through mechanical transmission, thereby removing the dust accumulated on the filter screen 35. The drive assembly 4 includes an intermediate plate 43 fixedly installed in the middle of the filter frame 34. The intermediate plate 43 is made of high-strength alloy steel plate and has sufficient rigidity to transmit driving force.

[0040] Multiple vibrating seats 44 are fixed at intervals along the length of the intermediate plate 43. The top of the vibrating seat 44 is designed as an arc-shaped contact surface, and the surface is hardened by quenching to improve its wear resistance and reduce wear caused by long-term impact. Inside the suction box 21, a rotating rod 41 is rotatably supported by a bearing seat. The rotating rod 41 is installed directly above the vibrating seat 44. On the rotating rod 41, corresponding to the position of each vibrating seat 44, a matching cam 42 is fixedly installed. When the profile of the cam 42 rotates, it can generate a regular vertical displacement, thereby forming a periodic impact force on the vibrating seat 44.

[0041] One end of the rotating rod 41 extends to the outer wall of the suction box 21 and is connected to a first bevel gear 45 by a key. A drive motor 46 is installed on one side of the converter cabinet 1 by a shock-absorbing bolt. The drive motor 46 is a servo motor, and its output speed can be precisely controlled by the controller. The rated power meets the transmission requirements. The output shaft of the drive motor 46 is connected to a second bevel gear 47 through a coupling. The second bevel gear 47 meshes with the first bevel gear 45 to form a vertical power transmission. By configuring the transmission ratio of the two gears, the speed and torque of the motor can be converted into the operating parameters required by the rotating rod 41, ensuring that the cam 42 can strike the vibration seat 44 with appropriate frequency and force.

[0042] like Figure 7 As shown, a dust collection component 5 is installed on the suction box 21. The main function of the dust collection component 5 is to collect the dust and impurities that fall off the filter component 3 during the vibration cleaning process, and at the same time facilitate subsequent cleaning and maintenance. The dust collection component 5 includes a collection box 51 fixedly installed at the bottom of the suction box 21. The collection box 51 is welded from stainless steel and has sufficient structural strength and sealing. Its volume design can meet the dust collection needs for a long period of time. At the lower end of the suction box 21, there is a dust discharge hole 52 that communicates with the inside of the collection box 51. The shape and position design of the dust discharge hole 52 ensures that the dust that falls off the filter component 3 can fall into it smoothly. The edge of the hole is smoothed to avoid forming a dust accumulation dead corner.

[0043] A drawer 53 is slidably installed inside the collection box 51. The drawer 53 is made of the same material as the collection box 51 and has a handle with a sealing gasket (not shown in the figure) installed at the front end, which facilitates the pulling operation and ensures good sealing when closed. An elastic sealing strip (not shown in the figure) is installed at the contact part between the collection box 51 and the drawer 53, which can effectively prevent dust from leaking from the gaps. A dust guide plate 54 is fixedly installed inside the collection box 51. The dust guide plate 54 is made of thin stainless steel plate bent and arranged in an inclined state. The inclined angle design can ensure that the dust slides down smoothly under the action of gravity and reduce the interference of airflow generated during the suction process on the dust falling. The surface of the dust guide plate 54 is polished to reduce the adhesion of dust.

[0044] The lower end of the dust guide plate 54 extends to the top of the drawer 53, and the outlet is directly opposite the central area of ​​the drawer 53, ensuring that all dust passing through the dust discharge hole 52 can fall accurately into the drawer 53, achieving efficient collection.

[0045] Working principle: When the equipment is running, the suction fan 22 in the suction assembly 2 is started under the control of the controller. The external air is sucked into the suction box 21 by the suction force of the fan. The air first flows through the filter screen 35 in the filter assembly 3. The outer layer of primary nylon mesh intercepts large particles of dust, hair and other impurities in the air. The filtered clean air enters the inside of the converter cabinet 1 through the air inlet rectangular hole 11.

[0046] Clean air comes into full contact with electrical components such as inverters and controllers inside the cabinet, absorbing the heat generated by the operation of the components. The resulting hot air is then discharged from the cabinet through the exhaust window 12 on the other side under the action of air pressure inside the cabinet, completing the heat dissipation cycle and ensuring that the internal components operate stably at a suitable temperature.

[0047] When the dust on the surface of the filter screen 35 accumulates to a certain extent and cleaning is required, the controller starts the drive assembly 4, the drive motor 46 runs, and its output shaft drives the second bevel gear 47 to rotate through the coupling. The first bevel gear 45, which meshes with the second bevel gear 47, rotates accordingly, thereby driving the rotating rod 41 to rotate. The cam 42 on the rotating rod 41 rotates synchronously, and the protruding part of the cam 42 periodically contacts the vibrating seat 44 and generates an impact force.

[0048] The impact force is transmitted to the filter frame 34 through the intermediate plate 43, causing the filter frame 34 to vibrate along the guide groove 341. Simultaneously, the filter frame 34 exerts a force on the spring 32 through the intermediate block 33. The spring 32 continuously expands and contracts under its elasticity, further amplifying the vibration amplitude of the filter frame 34. During continuous vibration, dust adhering to the surface of the filter screen 35 is shaken off, achieving self-cleaning.

[0049] The detached dust falls downwards under the influence of gravity and enters the dust guide plate 54 through the dust discharge hole 52 at the lower end of the suction box 21. Due to its inclined design and smooth surface, the dust guide plate 54 guides the dust to slide smoothly, reducing the accumulation at the opening. Finally, the dust falls into the drawer 53 inside the collection box 51. Subsequently, the staff periodically pulls out the drawer 53, cleans the collected dust, and resets it to maintain the continuous and effective operation of the filter assembly 3.

[0050] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
