Description

Technical Field

[0001] This utility model relates to the technical field of power distribution cabinets, and in particular to a multi-stage pull-out dustproof power distribution cabinet. Background Technology

[0002] A distribution cabinet, also known as a distribution box, is the final stage equipment in a power distribution system, primarily used in the motor control center. Distribution cabinets are generally classified into power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes). These devices distribute electrical energy from a circuit of the upstream power distribution equipment to the nearest load.

[0003] Although modern power distribution cabinets can be used stably, their dust prevention effect is generally achieved only by setting up dust screens. However, some fine dust can still enter and accumulate inside the cabinet. Since there are many electronic structures inside the cabinet and the space is small, it is not easy to clean. Long-term accumulation of dust will affect the use of the power distribution cabinet. Utility Model Content

[0004] In view of the above-mentioned problems of existing power distribution cabinets, the aim is to provide a multi-stage pull-out dustproof power distribution cabinet that is easy to clean and improves the cleaning effect.

[0005] The specific technical solution is as follows:

[0006] A multi-stage pull-out dustproof power distribution cabinet includes a cabinet body, the cabinet body having several heat dissipation slots communicating with the interior of the cabinet body, and further includes:

[0007] At least one pull-out assembly is provided, and at least one mounting groove is also provided inside the cabinet, wherein the pull-out assembly is slidably installed in the mounting groove.

[0008] At least one rotating cylinder is rotatably mounted on the inner wall of the mounting inner groove. Several airflow blades are distributed circumferentially on the outer wall of the rotating cylinder. The rotating cylinder is connected to the pull-out assembly via a transmission component. When the pull-out assembly slides in the mounting inner groove, the pull-out assembly drives the rotating cylinder to rotate via the transmission component, so that the several airflow blades drive the airflow in the mounting inner groove, thereby expelling the dust inside the mounting inner groove along with the air through the several heat dissipation slots.

[0009] As a further improvement and optimization of this solution, the transmission component includes: a threaded hole coaxially disposed on the rotating drum and a stud connected to the pull-out assembly. The stud is screwed to the threaded hole. When the pull-out assembly slides in the mounting inner groove, it drives the stud to move axially, thereby causing the rotating drum to rotate.

[0010] As a further improvement and optimization of this solution, the power distribution cabinet also includes at least one fan cover. One side of the fan cover is installed on the inner wall of the bottom of the mounting groove. The rotating drum is coaxially rotatably installed inside the fan cover, and one end of the rotating drum passes through the other side of the fan cover and is threaded onto the outside of the stud through the threaded hole.

[0011] As a further improvement and optimization of this solution, the inner wall of the shroud is coaxially provided with several airflow grooves, and the shroud has several air holes.

[0012] As a further improvement and optimization of this solution, the pull-out assembly includes: a pull-out cabinet, which is slidably installed in the mounting groove, and the studs are installed on the inner side of the pull-out cabinet.

[0013] As a further improvement and optimization of this solution, a dust scraper is elastically connected to the bottom of the pull-out cabinet, and the bottom of the dust scraper contacts the bottom inner wall of the mounting inner groove.

[0014] As a further improvement and optimization of this solution, the bottom cross-section of the dust scraper has a triangular structure.

[0015] As a further improvement and optimization of this solution, the dust scraper is connected to the bottom of the drawer cabinet by several springs.

[0016] As a further improvement and optimization of this solution, the inner walls on both sides of the mounting groove are equipped with slide rails, and the two sides of the pull-out cabinet are equipped with slide grooves, with the two slide grooves respectively slidingly engaging with the two slide rails.

[0017] As a further improvement and optimization of this solution, multiple pull-out components are provided, and multiple mounting slots are correspondingly provided.

[0018] The positive effects of the above technical solution compared with the existing technology are:

[0019] (1) In this utility model, the pull-out assembly can be pulled inward or outward to slide in the inner groove of the installation, so that the pull-out assembly drives the rotating cylinder to rotate through the transmission component, and causes several airflow blades to drive the air flow in the inner groove of the installation, thereby discharging the dust inside the inner groove of the installation along with the air through several heat dissipation slots, which facilitates the dust cleaning work inside the cabinet.

[0020] (2) When performing maintenance in the power distribution cabinet, the inside of the power distribution cabinet can be exposed by pulling out the cabinet, which facilitates maintenance. At the same time, during the process of pulling out the power distribution cabinet, the screw and the threaded hole can drive the rotating drum to rotate, so that several airflow blades can drive the air in the inner groove to flow, thereby cleaning the dust inside the cabinet and improving the overall application effect of the cabinet.

[0021] (3) In this utility model, a dust scraper is elastically connected to the bottom of the pull-out cabinet. When the pull-out cabinet is pulled out, the dust scraper can be closely attached to the bottom inner wall of the mounting inner groove and scrape the dust attached to the bottom inner wall of the mounting inner groove out of the groove opening, further improving the dust removal effect of the power distribution cabinet.

[0022] (4) In order to improve the dust scraping effect of the dust scraper, the bottom cross section of the dust scraper is triangular. Attached Figure Description

Figure 5 This is a schematic diagram of the pull-out assembly of a multi-stage pull-out dustproof power distribution cabinet according to this utility model. Figure 1 The diagram illustrates a preferred embodiment of a multi-stage pull-out dustproof power distribution cabinet, comprising a cabinet body 1 with several heat dissipation slots 11 communicating with the interior of the cabinet body 1, and further including at least one pull-out assembly 3 and at least one rotating cylinder 5. At least one mounting inner groove 13 is also provided inside the cabinet body 1. The pull-out assembly 3 is slidably mounted within the mounting inner groove 13, and the rotating cylinder 5 is rotatably mounted on the inner wall of the mounting inner groove 13. Several airflow blades 6 are circumferentially distributed on the outer wall of the rotating cylinder 5. The rotating cylinder 5 and the pull-out assembly 3 are connected by a transmission component. When the pull-out assembly 3 slides within the mounting inner groove 13, the pull-out assembly 3 drives the rotating cylinder 5 to rotate via the transmission component, causing the airflow blades 6 to move the air within the mounting inner groove 13, thereby discharging dust from inside the mounting inner groove 13 along with the air through the several heat dissipation slots 11.

[0033] In this embodiment, the pull-out assembly 3 can be slid inward or outward within the mounting inner groove 13, so that the pull-out assembly 3 drives the rotating cylinder 5 to rotate through the transmission component, and causes several airflow blades 6 to drive the airflow within the mounting inner groove 13, thereby discharging the dust inside the mounting inner groove 13 along with the air through several heat dissipation slots 11, which facilitates the dust cleaning work inside the cabinet 1.

[0034] More preferably, a number of heat dissipation slots 11 are distributed on the two sides and the rear side of the cabinet 1, and the mounting inner slot 13 is located on the front side of the cabinet 1, and the mounting inner slot 13 is in communication with the number of heat dissipation slots 11.

[0035] Furthermore, as a preferred embodiment, the transmission component includes: a threaded hole 51 coaxially disposed on the rotating drum 5 and a stud 7 connected to the pull-out assembly 3. The stud 7 is screwed to the threaded hole 51. When the pull-out assembly 3 slides in the mounting inner groove 13, it drives the stud 7 to move axially, so as to make the rotating drum 5 rotate.

[0036] More specifically, the outer wall of the stud 7 has at least one threaded slide bar wound along the axial direction, and the inner wall of the threaded hole 51 has at least one threaded groove wound along the axial direction. The threaded slide bar and the threaded groove slide in a sliding fit (equivalent to a screw connection). When the stud 7 moves along the axial direction, the threaded slide bar slides relative to each other in the threaded groove, thereby driving the rotating drum 5 to rotate.

[0037] Furthermore, as a preferred embodiment, the distribution cabinet also includes at least one fan cover 4. One side of the fan cover 4 is installed on the inner wall of the bottom of the mounting groove 13. The rotating drum 5 is coaxially rotatably installed inside the fan cover 4, and one end of the rotating drum 5 passes through the other side of the fan cover 4 and is threaded onto the outside of the stud 7 through the threaded hole 51.

[0038] Furthermore, as a preferred embodiment, in order to increase the airflow velocity driven by the airflow blades 6, the inner wall of the shroud 4 is coaxially provided with several airflow grooves 41, and the shroud 4 has several air holes 42. The airflow blades 6 drive the airflow to flow in the airflow grooves 41 and blow it out through each air hole 42, thereby discharging the dust through each heat dissipation hole.

[0039] Furthermore, as a preferred embodiment, the pull-out assembly 3 includes: a pull-out cabinet 31, which is slidably installed in the mounting groove 13, and studs 7 are installed on the inner side of the pull-out cabinet 31.

[0040] To facilitate the pulling action of the drawer cabinet 31, the front side of the drawer cabinet 31 has a handle 32.

[0041] In this embodiment, when maintenance is carried out inside the distribution cabinet, the interior of the distribution cabinet can be exposed by pulling out the cabinet 31, which facilitates maintenance. At the same time, during the process of pulling out the distribution cabinet, the screw 7 and the threaded hole 51 can drive the rotating drum 5 to rotate, so that several airflow blades 6 can drive the air in the inner groove 13 to flow, thereby cleaning the dust in the cabinet 1 and improving the overall application effect of the cabinet 1.

[0042] Furthermore, as a preferred embodiment, a dust scraper 33 is elastically connected to the bottom of the pull-out cabinet 31, and the bottom of the dust scraper 33 contacts the bottom inner wall of the mounting inner groove 13.

[0043] In this embodiment, a dust scraper 33 is elastically connected to the bottom of the pull-out cabinet 31. When the pull-out cabinet 31 is pulled out, the dust scraper 33 can fit tightly against the bottom inner wall of the mounting inner groove 13 and scrape the dust attached to the bottom inner wall of the mounting inner groove 13 out of the groove opening of the mounting inner groove 13, further improving the dust removal effect of the power distribution cabinet.

[0044] Furthermore, as a preferred embodiment, in order to improve the dust scraping effect of the dust scraper 33, the bottom cross section of the dust scraper 33 is triangular.

[0045] Furthermore, as a preferred embodiment, the dust scraper 33 is connected to the bottom of the drawer cabinet 31 by a number of springs 34.
