Detailed Implementation

[0044] The core of this application is to disclose a power equipment that reduces the maintenance costs of power equipment.

[0045] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the utility model as described in the claims. Additionally, the complete contents of the structures represented in the embodiments below are not limited to those necessary for the solution of the utility model as described in the claims. It should be noted that, for ease of description, only the parts relevant to the utility model are shown in the drawings. Unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0046] Combination Figures 1-15The power equipment disclosed in this application includes a cabinet 600 and a filter body 100. The filter body 100 is mounted on the cabinet 600 and includes at least two filter sub-bodies 110. Each filter sub-bodies 110 has a filter chamber 111, and filter material 400 is disposed within the filter chamber 111. The filter sub-bodies 110 are connected, and the filter chambers 111 of each filter sub-bodies 110 are sequentially connected, connecting the internal space of the cabinet 600 to the outside world to meet the gas exchange requirements of the power equipment. As outside air enters the cabinet 600, it passes through each filter chamber 111 sequentially and is filtered multiple times by the filter material 400 within each filter chamber 111. The filter material 400 adsorbs moisture and impurities in the air to ensure that only dry and clean air enters the cabinet 600. These impurities may include gaseous pollutants such as salt spray, halogens, sulfides, and nitrogen oxides, as well as dust.

[0047] The specific types of power equipment include, but are not limited to, photovoltaic equipment and energy storage power equipment. For example, in some embodiments, electronic components such as circuit boards 700 are installed inside the cabinet 600. The cabinet 600 includes a housing 620 and a cover plate 610. The housing 620 and the cover plate 610 are connected and together form the enclosed internal space of the cabinet 600. The filter body 100 can be installed on the housing 620 or the cover plate 610.

[0048] Compared to existing technologies, the power equipment disclosed in this application can be equipped with different filter materials 400 in different filter chambers 111, thereby enabling multiple and reliable adsorption of moisture and various impurities in the air, thus ensuring the dryness and purity of the gas inside the cabinet 600, reducing the risk of damage to electronic components, and thus reducing the maintenance cost of the power equipment.

[0049] The connection methods of the various filter chambers 111 are including but not limited to sequential connection along the axial direction, sequential connection along the radial direction, and combinations of both, which can be specifically designed according to the positional arrangement and connection form of each filter sub-body 110. In some embodiments, combined with Figure 1 and Figure 2 The filter chamber 111 is axially connected to the filter sub-body 110. In addition, each filter sub-body 110 is arranged and connected in sequence along the axial direction, and the filter chamber 111 of two adjacent filter sub-body 110 is connected. In this embodiment, each filter sub-body 110 can be made with the same structure, which is simple and easy to manufacture.

[0050] A further optimized design allows for the detachable connection of two adjacent filter sub-body 110. For example, combining... Figure 2This paper illustrates a technical solution in which various filter sub-body 110 are arranged sequentially along the axial direction and are detachably connected. Since the different filter sub-body 110 can be disassembled from each other, when the filter material 400 inside a certain filter sub-body 110 needs to be replaced, it can be directly disassembled and replaced, further reducing maintenance costs.

[0051] The types of filter materials 400 include, but are not limited to, activated carbon, fiber agents, desulfurizing agents, filter cotton, adsorption purification nets, and polymer waterproof and breathable materials. The types of filter materials 400 in each filter chamber 111 can be the same or different, and each filter chamber 111 can have one or more types of filter materials 400. The specific configuration can be made according to the actual application scenario of the power equipment to keep costs under control.

[0052] In some embodiments, each filter chamber 111 is filled with filter material 400 that primarily adsorbs and filters impurities of different components. Since the moisture and impurity content in the air varies in different environments, the replacement frequency of the filter material 400 in different filter chambers 111 varies accordingly, thereby achieving targeted periodic maintenance and reducing costs. For example, when power equipment is used in coastal areas, coal mines, or chemical industrial zones, gaseous pollutants such as salt spray, halogens, sulfur dioxide, and hydrogen sulfide may exist in the environment. These pollutants can penetrate the interior of the power equipment, contaminating circuit components, significantly reducing the reliability of the entire machine, shortening its lifespan, and increasing the failure rate. Therefore, activated carbon can be arranged in the first filter chamber 111 to adsorb and filter salt spray, halogens, sulfur dioxide, and hydrogen sulfide; chemical filter material can be arranged in the second filter chamber 111 to filter hydrogen sulfide; and an adsorption purification mesh and / or a waterproof and breathable mesh can be arranged in the third filter chamber 111 to adsorb moisture. The filter body 100 disclosed in this application can simultaneously possess the functions of breathability, waterproofing, and pollution prevention, and has better maintainability.

[0053] Combination Figure 2 and Figure 5 In some embodiments, along the axial direction, the first end of the filter sub-body 110 is provided with a first threaded structure 113, and the second end is provided with a second threaded structure. The first threaded structures 113 and second threaded structures of adjacent filter sub-body 110 are threadedly engaged to achieve a detachable connection. In other embodiments, along the axial direction, the first end of the filter sub-body 110 is provided with a first snap-fit ​​structure, and the second end is provided with a second snap-fit ​​structure. The first snap-fit ​​structures and second snap-fit ​​structures of adjacent filter sub-body 110 are snap-fit ​​engaged to achieve a detachable connection. This design is simple in structure, convenient to manufacture, quick to assemble and disassemble, and has low maintenance costs.

[0054] To further optimize the design, a first sealing element 500 is pressed between two adjacent filter sub-body 110. This first sealing element 500 prevents air leakage at the connection point of the two adjacent filter sub-body 110, which would allow outside air containing moisture and impurities to enter the cabinet 600 directly without passing through the filter material 400 within the entire filter chamber 111, thus affecting the lifespan of the electronic components inside the cabinet 600. The first sealing element 500 can be, but is not limited to, sealing rings or gaskets. To facilitate the positioning and installation of the first sealing element 500, a corresponding sealing element mounting groove can be provided at the axial end of the filter sub-body 110 to facilitate the embedding and positioning of the first sealing element 500.

[0055] Combination Figure 2 , Figure 5 and Figure 6 At least one separator 112 is provided within the filter chamber 111. The separator 112 is used to intercept the filter material 400, preventing the filter material 400 from moving within each filter chamber 111 and from entering the cabinet 600 or exiting the filter body 100. Depending on the type of filter material 400 within each filter chamber 111, the structure of each separator 112 can also differ, as long as it prevents the filter material 400 from falling out and does not impede airflow. For example, in combination with… Figure 7 The intercepting portion of the separator 112 can have a cross-shaped, mesh-like, or other structure. Combined with... Figure 5 and Figure 6 The filter body 110 and the separator 112 can be an integral structure or a separate structure.

[0056] To facilitate the installation of the filter unit 100 and the cabinet 600, combined with Figure 3 The filter body 100 also includes a mounting part 200, which is located at the first end of the filter body 100 along the axial direction. The first end of the mounting part 200 is connected to the filter sub-body 110, and the second end is connected to the cabinet 600. An obstacle hole 201 is provided through the mounting part 200 along the axial direction. The two ends of the obstacle hole 201 are respectively connected to the filter chamber 111 and the internal space of the cabinet 600 to allow air flow and balance the internal and external air pressure of the cabinet 600.

[0057] To avoid affecting the disassembly and maintenance of each filter element 110, the first end of the mounting part 200 is detachably connected to the filter element 110. The second end of the mounting part 200 can be detachably or fixedly connected to the cabinet 600. A detachable connection facilitates disassembly and maintenance.

[0058] To achieve the connection between the mounting section 200, the filter sub-body 110, and the cabinet 600, combined with Figure 8 and Figure 9The mounting section 200 has a first connection structure 210 at its first end for connecting to the filter sub-body 110, and a second connection structure 220 at its second end for connecting to the cabinet 600. For example, combined with... Figure 9 The first connecting structure 210 may include a first mounting protrusion, and the first mounting protrusion is provided with an external thread for threaded connection with the filter body 110. The second connecting structure 220 may include a second mounting protrusion, and the second mounting protrusion is provided with an external thread. After passing through the side wall of the cabinet 600, the second mounting protrusion can be tightened and fixed to the cabinet 600 by a mounting nut. The structure is simple and easy to assemble and disassemble. In addition to the above-mentioned nut fixing, the connection methods between the mounting part 200 and the cabinet 600 include, but are not limited to, direct threaded connection, adhesive bonding, and snap-fit ​​connection.

[0059] Further optimize the plan, combined with Figure 1 A second seal 510 is pressed between the mounting part 200 and the filter body 100. The second seal 510 prevents air leakage at the connection point between the filter body 100 and the mounting part 200, which would allow outside air containing impurities and moisture to enter the cabinet 600 directly without being filtered by the filter material 400 inside the filter chamber 111, thus affecting the lifespan of the electronic components inside the cabinet 600. The second seal 510 may include, but is not limited to, sealing rings and gaskets. To facilitate the positioning and installation of the second seal 510, corresponding sealing grooves can be formed on the mutually facing and mating surfaces of the filter body 100 and the mounting part 200 to facilitate the embedding and positioning of the second seal 510.

[0060] In some embodiments, a third seal is also pressed between the mounting section 200 and the cabinet 600. The third seal is used to prevent air leakage at the connection between the mounting section 200 and the cabinet 600, which would allow outside air containing impurities to enter the cabinet 600 directly without being filtered by the filter material 400, affecting the lifespan of the electronic components inside the cabinet 600. Accordingly, a seal mounting groove for positioning and installing the third seal can be provided on the mounting section 200 and / or the cabinet 600.

[0061] Since each filter chamber 111 on the filter body 100 is linearly connected along the axial direction, in order to prevent air from passing straight through the filter chamber 111 and entering the cabinet 600, combined with... Figure 1The filter body 100 also includes an end cap 300, which is disposed at the second end of the filter body 100 in the axial direction. An air gap 301 communicating with the filter chamber 111 is provided between the end cap 300 and the filter body 100. Outside air, blocked by the end cap 300, flows through the filter chamber 111 and into the cabinet 600 via the air gap 301 between the end cap 300 and the filter body 100, or flows in the opposite direction. The end cap 300 effectively reduces the amount of gas exchange between the cabinet 600 and the external environment, thereby extending the service life of the filter material 400 and reducing production costs.

[0062] Specifically, the end cap 300 and the filter body 100 can be an integral or separate structure. When it is an integral structure, it is convenient to manufacture by injection molding, reducing production costs. When it is a separate structure, it is convenient to replace the filter material 400 in the filter chamber 111 by removing the end cap 300.

[0063] In some embodiments, the filter body 100 and the end cap 300 are detachably connected. The mutually facing surfaces of the filter body 100 and the end cap 300 are defined as a first surface and a second surface, respectively. A positioning post is provided on one of the first and second surfaces, and a positioning hole is provided on the other surface for the end of the positioning post to be inserted. The positioning post is used to create the aforementioned air gap 301 between the first and second surfaces. The positioning posts can be evenly distributed circumferentially around the axis of the filter body 100 to ensure the uniformity of the airflow direction.

[0064] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Specific technical means in some embodiments may be incorporated, in whole or in part, into another embodiment unless explicitly excluded by another embodiment. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
