[0003] In modern power supply systems, as a key device, the power distribution cabinet undertakes the important tasks of distributing, controlling, and protecting electric energy. Facing increasingly complex power demands and diverse installation environments, traditional power distribution cabinets expose many problems. Existing power distribution cabinets also have deficiencies in aspects such as heat dissipation, waterproofing, and the convenience of installing, disassembling, and overhauling electrical equipment, which affect the performance and service life of the power distribution cabinet, and thus have an adverse impact on the stability and reliability of power supply.

[0005] A ventilation component, the ventilation component is fixedly installed on both sides of the outer surface of the cabinet body, and the ventilation component is communicated with the interior of the cabinet body;

[0006] A moisture-proof and heat-dissipating component, a support rod is fixedly installed on the outer surface of the moisture-proof and heat-dissipating component, there are two support rods, both of the two support rods are fixedly installed on the inner wall of the cabinet body, the moisture-proof and heat-dissipating component is fixedly installed on both sides inside the cabinet body through the support rods, and the moisture-proof and heat-dissipating component penetrates through the cabinet body and extends into the interior of the ventilation component;

[0007] The installation component is fixedly installed between adjacent surfaces of the moisture-proof heat dissipation component, and the installation component is mounted inside the cabinet through the moisture-proof heat dissipation component. When the power distribution cabinet is in use, the staff installs the electrical components on top of the installation component. Since the electrical components in the power distribution cabinet will generate heat during long-term operation, the temperature in the power distribution cabinet will rise and condense water vapor. At this time, the moisture-proof heat dissipation components and ventilation components arranged on both sides of the power distribution cabinet are in a connected state to transport the high-temperature airflow in the cabinet to the outside, so that the airflow inside and outside the cabinet is exchanged. When the cold and hot airflows are exchanged, the condensed water vapor is collected in the moisture-proof heat dissipation component, and while the cabinet is ventilated and cooled, water vapor is prevented from gathering in the cabinet to cause a short circuit.

[0008] Preferably, the moisture-proof heat dissipation component includes a mounting frame, and four mounting frames are provided. Positioning rings are fixedly installed at both ends of the outer surfaces of the four mounting frames, and the surfaces of the positioning rings are provided with circulation grooves. Collecting pieces are fixedly installed inside the positioning rings, and an inner rotating piece is rotatably installed inside the collecting piece. The collecting piece is installed inside the cabinet through the positioning ring and passes through the cabinet to communicate with the ventilation component. When the electrical components in the cabinet generate heat, the high-temperature airflow will flow to the low-temperature area outside the cabinet to flow into the ventilation component along the collecting piece. At this time, the low-temperature airflow in the area of the collecting piece close to the ventilation component converges with the high-temperature airflow and condenses water vapor. When the airflow outside the cabinet enters the cabinet, the collecting piece absorbs dust in the air to reduce the dust in the cabinet and perform dust-proof treatment on the cabinet.

[0009] Preferably, the mounting frame is fixedly mounted on the outer surface of the support rod, the mounting frame is fixedly mounted on both sides of the interior of the cabinet through the support rod, and the collecting member penetrates the inner wall of the cabinet and extends into the ventilation assembly.

[0010] Preferably, the collecting member includes a snap ring, an extension cover is fixedly mounted on the outer surface of the snap ring, an inner filter is fixedly mounted inside the extension cover, a circular hole is provided on the surface of the inner filter, and a connecting ring is fixedly mounted on the outer surface of the extension cover and the inner filter. The collecting member is arranged as a double-layer structure, the circular hole provided on the surface of the inner filter enables the extension cover and the inner filter assembly to form a collecting chamber, and the extension cover and the inner filter are arranged as a trumpet-shaped structure, the opening on one side of the cabinet is larger, so as to facilitate the high-temperature airflow in the cabinet to be led outward, and the opening on one side of the ventilation assembly is smaller, when the airflow outside the cabinet flows and exchanges into the cabinet, the airflow follows the connecting ring through the inner filter into the collecting chamber, and at this time, the water vapor collected in the collecting chamber adsorbs the dust in the air.

[0011] Preferably, the clamping ring is fixedly installed inside the positioning ring, the extension cover penetrates through the cabinet body and extends into the ventilation component, and the inner filter screen is rotationally adapted to the inner rotating member. When air flows inside the inner filter screen, the air flow fluctuation will push the inner rotating member to rotate inside the inner filter screen, improving the air circulation rate while preventing impurities in the outside air from entering the cabinet body.

[0012] Preferably, the inner rotating member includes a circular ring, a clamping ring rod is fixedly installed on the outer surface of the circular ring, the clamping ring rod is rotationally installed on the surface of the inner filter screen, there are four clamping ring rods, and a positioning seat is fixedly installed between adjacent surfaces of the four clamping ring rods, and a spherical ball is fixedly installed inside the positioning seat. When the air flow moves, it pushes the clamping ring rod to rotate inside the inner filter screen and drives the spherical ball to rotate accordingly. Since the inner filter screen is arranged in a trumpet shape, when the air flow flows from one end of the clamping ring towards the connection ring, the opening of the inner filter screen is large and the air flow can quickly pass through between the spherical ball and the inner filter screen. When the air flow flows from one end of the connection ring towards the clamping ring, the opening of the inner filter screen is small, and when the air flow moves, it is limited by the spherical ball and diffuses towards the surrounding collection cavity, so it will contact the condensed water vapor in the collection cavity, settle dust and then enter the cabinet body, so as to achieve the purpose of dust reduction and diversion of the air flow entering the cabinet body.

[0013] Preferably, the ventilation component includes an external cover, there are two external covers, and the two external covers are respectively fixedly installed on both sides of the outer surface of the cabinet body. Inclined grooves are opened at the edges of the top of the external cover, and ventilation holes are opened on the surface of the external cover. The external cover protects the collection component to prevent larger impurities from entering the collection component and causing blockage of the collection component, which affects the heat dissipation effect. The inclined grooves provided at the top of the external cover divert rainwater to prevent rainwater accumulation on the protective cover, which affects the service life of the power distribution cabinet.

[0014] Preferably, the external cover is connected to the cabinet body through the collection component, and the external cover covers the outside of the collection component.

[0015] Preferably, the installation component includes positioning blocks, there are two groups of positioning blocks, extrusion grooves are respectively provided inside the two groups of positioning blocks, a limit clamping frame is fixedly installed on the side of the outer surface of the positioning block, a placement plate is fixedly installed between adjacent surfaces of the limit clamping frame, and a guide groove is opened inside the placement plate. The staff installs the electrical components of the smart grid above the placement plate. The guide groove opened on the surface of the placement plate guides the air flow inside the cabinet body while reducing the contact area between the placement plate and the electrical components, so as to facilitate the heat dissipation treatment of the electrical components.

[0016] Preferably, the positioning blocks are fixedly installed inside the installation frame, and the placement plate is arranged inside the cabinet body through the positioning block frame.

[0017] The present invention provides a power distribution cabinet for power supply installation, which has the following beneficial effects:

[0018] First, for the power distribution cabinet for power supply installation, when it is in use, the staff installs the electrical components above the installation assembly. Since the electrical components in the power distribution cabinet generate heat during long-term operation, the temperature inside the power distribution cabinet rises and water vapor condenses. At this time, the moisture-proof and heat-dissipating components and the ventilation components on both sides inside the power distribution cabinet are in a connected state to convey the high-temperature air flow inside the cabinet to the outside, so as to exchange the air flow inside and outside the cabinet. The water vapor condensed during the exchange of hot and cold air flows is collected into the moisture-proof and heat-dissipating components, avoiding the water vapor from gathering inside the cabinet and causing a short circuit of the circuit while ventilating and cooling the inside of the cabinet.

[0019] Second, for the power distribution cabinet for power supply installation, the collecting part is installed inside the cabinet body through the positioning ring and penetrates the cabinet body to be connected with the ventilation component. When the electrical components in the cabinet body generate heat during operation, the high-temperature air flow will flow towards the low-temperature area outside the cabinet body and flow into the ventilation component along the collecting part. At this time, the low-temperature air flow in the area of the collecting part close to the ventilation component converges with the high-temperature air flow and condenses into water vapor. The collecting part collects the water vapor. When the air flow outside the cabinet body enters the cabinet body, the collecting part adsorbs the dust in the air to reduce the dust in the cabinet body and perform dust-proof treatment on the cabinet body.

[0020] Third, for the power distribution cabinet for power supply installation, the collecting part is set as a double-layer structure. The round holes formed on the surface of the inner-layer filter screen enable the extension cover and the inner-layer filter screen assembly to form a collecting cavity, and the extension cover and the inner-layer filter screen are set as a horn-shaped structure, with a larger opening on one side of the cabinet body to facilitate the outward export of the high-temperature air flow inside the cabinet, and a smaller opening on the side of the ventilation component. When the air flow outside the cabinet body flows into the cabinet body for exchange, the air flow enters the collecting cavity through the inner-layer filter screen along the connecting ring. At this time, the water vapor collected in the collecting cavity adsorbs the dust in the air.

[0021] Fourth, for the power distribution cabinet for power supply installation, when the air flow moves, it pushes the snap ring rod to rotate inside the inner-layer filter screen and drives the spherical ball to rotate accordingly. Since the inner-layer filter screen is set as a horn-shaped structure, when the air flow flows from one end of the clamping ring to the connecting ring, the opening of the inner-layer filter screen is larger and the air flow can quickly pass through between the spherical ball and the inner-layer filter screen. When the air flow flows from one end of the connecting ring to the clamping ring, the opening of the inner-layer filter screen is smaller and the air flow is limited by the spherical ball during flow and diffuses to the surrounding collecting cavities, so that it will contact the condensed water vapor in the collecting cavity to reduce dust and then enter the cabinet body, so as to achieve the purpose of dust reduction and flow guiding for the air flow entering the cabinet body.

[0022] V. For the power distribution cabinet used for power supply installation, the electrical components of the smart grid are installed above the placement board by the staff. The guide grooves opened on the surface of the placement board direct the airflow in the cabinet while reducing the contact area between the placement board and the electrical components, so as to facilitate the heat dissipation of the electrical components. The external cover protects the collection part to prevent large impurities from entering the collection part and causing blockage of the collection part, which affects the heat dissipation effect. The inclined groove provided at the top of the external cover diverts rainwater to prevent rainwater accumulation on the protective cover, which affects the service life of the power distribution cabinet.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] The first embodiment is as Figures 1 to 10 shown. The present invention provides a technical solution: a power distribution cabinet for power supply installation, including: a cabinet body 5, a protective cover 1 is fixedly installed on the top of the cabinet body 5, a protective door 2 is rotatably installed on the outer surface of the cabinet body 5, and support legs 3 are fixedly installed at the bottom of the cabinet body 5;

[0037] Preferably, the ventilation component 4 includes an external cover 42. There are two external covers 42, and the two external covers 42 are respectively fixedly installed on both sides of the outer surface of the cabinet body 5. Inclined grooves 41 are opened at the side edges of the top of the external cover 42, and ventilation holes 43 are opened on the surface of the external cover 42. The external cover 42 protects the collection piece 83 to prevent larger impurities from entering the collection piece 83 and causing blockage of the collection piece 83 and affecting the heat dissipation effect. The inclined grooves 41 provided at the top of the external cover 42 divert rainwater to prevent rainwater accumulation on the protective cover 1 and affecting the service life of the power distribution cabinet.

[0038] Preferably, the external cover 42 is communicated with the cabinet body 5 through the collection piece 83, and the external cover 42 covers the outside of the collection piece 83.

[0039] Moisture-proof and heat-dissipating component 8, two support rods 7 are fixedly installed on the outer surface of the moisture-proof and heat-dissipating component 8, and both of the two support rods 7 are fixedly installed on the inner wall of the cabinet body 5. The moisture-proof and heat-dissipating component 8 is fixedly installed on both sides inside the cabinet body 5 through the support rods 7, and the moisture-proof and heat-dissipating component 8 penetrates through the cabinet body 5 and extends into the ventilation component 4;

[0040] Preferably, the moisture-proof and heat-dissipating component 8 includes four mounting frames 82. At both ends of the outer surfaces of the four mounting frames 82, positioning rings 81 are fixedly installed. Flow grooves 84 are formed on the surfaces of the positioning rings 81, collecting members 83 are fixedly installed inside the positioning rings 81, and inner rotating members 85 are rotatably installed inside the collecting members 83. The collecting members 83 are installed inside the cabinet body 5 through the positioning rings 81 and are communicated with the ventilation component 4 through the cabinet body. When the electrical components inside the cabinet body 5 operate to generate heat, the high-temperature air flow will flow towards the low-temperature area outside the cabinet body 5 and flow into the ventilation component 4 along the collecting members 83. At this time, the low-temperature air flow in the area of the collecting members 83 close to the ventilation component 4 converges with the high-temperature air flow and condenses into water vapor. The collecting members 83 collect the water vapor. When the air flow outside the cabinet body 5 enters the cabinet body 5, the collecting members 83 adsorb and process the dust in the air to reduce the dust in the cabinet body 5 and perform dust-proof treatment on the cabinet body 5.

[0041] Preferably, the mounting frames 82 are fixedly installed on the outer surfaces of the support rods 7, and the mounting frames 82 are fixedly installed on both sides inside the cabinet body 5 through the support rods 7. The collecting members 83 penetrate through the inner wall of the cabinet body 5 and extend into the ventilation component 4.

[0042] Mounting component 6, the mounting component 6 is fixedly installed between adjacent surfaces of the moisture-proof and heat-dissipating component 8, and the mounting component 6 is erected inside the cabinet body 5 through the moisture-proof and heat-dissipating component 8. When the power distribution cabinet is in use, the staff installs the electrical components above the mounting component 6. Since the electrical components inside the power distribution cabinet generate heat during long-term operation, the temperature inside the power distribution cabinet rises and condenses into water vapor. At this time, the moisture-proof and heat-dissipating components 8 arranged on both sides inside the power distribution cabinet are in communication with the ventilation component 4 to convey the high-temperature air flow inside the cabinet body 5 to the outside, so as to exchange the air flow inside and outside the cabinet body 5. The water vapor condensed during the exchange of hot and cold air flows is collected into the moisture-proof and heat-dissipating component 8, while ventilating and cooling the inside of the cabinet body 5, avoiding the water vapor from gathering inside the cabinet body 5 and causing a short circuit of the circuit.

[0043] Preferably, the installation assembly 6 includes positioning blocks 62, and the positioning blocks 62 are provided with two groups, and the inside of the two groups of positioning blocks 62 are both provided with extrusion grooves 64, and the side of the outer surface of the positioning blocks 62 is fixedly installed with a limit card frame 65, and a placement plate 61 is fixedly installed between adjacent surfaces of the limit card frame 65, and the inside of the placement plate 61 is provided with a guide groove 63. The staff installs the electrical components of the smart grid above the placement plate 61, and the guide groove 63 provided on the surface of the placement plate 61 guides the airflow in the cabinet 5 while reducing the contact area between the placement plate 61 and the electrical components, so as to facilitate the heat dissipation of the electrical components.

[0044] Preferably, the positioning block 62 is fixedly mounted inside the mounting frame 82 , and the placement plate 61 is arranged inside the cabinet 5 via the positioning block 62 .

[0045] The second embodiment is based on the first embodiment. Figures 6 to 9 As shown, preferably, the collecting member 83 includes a snap ring 831, an extension cover 835 is fixedly installed on the outer surface of the snap ring 831, an inner filter 832 is fixedly installed inside the extension cover 835, a circular hole 834 is opened on the surface of the inner filter 832, and a connecting ring 833 is fixedly installed on the outer surface of the extension cover 835 and the inner filter 832. The collecting member 83 is set as a double-layer structure, and the circular hole 834 opened on the surface of the inner filter 832 enables the extension cover 835 and the inner filter 832 assembly to form a collecting chamber, and the extension cover 835 and the inner filter 832 are set as a trumpet-shaped structure, the opening on one side of the cabinet 5 is larger, so that the high-temperature airflow in the cabinet 5 is easily led out, and the opening on the side of the ventilation component 4 is smaller. When the airflow outside the cabinet 5 flows into the cabinet 5, the airflow enters the collecting chamber along the connecting ring 833 through the inner filter 832, and the water vapor collected in the collecting chamber adsorbs the dust in the air.

[0046] Preferably, the clamping ring 831 is fixedly installed inside the positioning ring 81, the extension cover 835 extends through the cabinet 5 to the inside of the ventilation assembly 4, and the inner filter 832 is rotatably adapted to the inner rotating member 85. When air flows in the inner filter 832, air flow fluctuations will push the inner rotating member 85 to rotate in the inner filter 832, thereby increasing the air circulation rate and preventing impurities in the outside air from entering the cabinet 5.

[0047] The third embodiment is based on the first and second embodiments. Figures 8 to 10As shown, preferably, the inner rotating member 85 includes a circular ring 854. A clamping ring rod 851 is fixedly installed on the outer surface of the circular ring 854. The clamping ring rod 851 is rotatably installed on the surface of the inner filter screen 832. There are four clamping ring rods 851. A positioning seat 852 is fixedly installed between adjacent surfaces of the four clamping ring rods 851. A spherical ball 853 is fixedly installed inside the positioning seat 852. When the air flows, it pushes the clamping ring rod 851 to rotate inside the inner filter screen 832 and drives the spherical ball 853 to rotate accordingly. Since the inner filter screen 832 is arranged in a horn shape, when the air flows from one end of the clamping ring 831 to the connection ring 833, the opening of the inner filter screen 832 is large and the air can quickly pass through between the spherical ball 853 and the inner filter screen 832. When the air flows from one end of the connection ring 833 to the clamping ring 831, the opening of the inner filter screen 832 is small and the air flow is limited by the spherical ball 853 and diffuses to the surrounding collection cavity, so that it will contact the condensed water vapor in the collection cavity and then enter the cabinet 5 after dust removal, so as to achieve the purpose of dust removal and diversion of the air flowing into the cabinet 5.

[0048] During use, when the power distribution cabinet is in use, the staff installs the electrical components above the installation component 6. Since the electrical components in the power distribution cabinet generate heat during long-term operation, the temperature in the power distribution cabinet rises and water vapor condenses. At this time, the moisture-proof and heat-dissipating components 8 and the ventilation component 4 arranged on both sides inside the power distribution cabinet are in a connected state to transport the high-temperature air flow inside the cabinet 5 to the outside, so as to exchange the air flow inside and outside the cabinet 5. The water vapor condensed during the exchange of cold and hot air flows is collected into the moisture-proof and heat-dissipating component 8, while ventilating and cooling the inside of the cabinet 5, preventing water vapor from gathering inside the cabinet 5 and causing a short circuit of the circuit.

[0049] The staff installs the electrical components of the smart grid above the placement plate 61. The guide grooves 63 opened on the surface of the placement plate 61 guide the air flow inside the cabinet 5 while reducing the contact area between the placement plate 61 and the electrical components, so as to facilitate the heat dissipation of the electrical components.

[0050] The collecting member 83 is installed inside the cabinet 5 through the positioning ring 81 and is connected to the ventilation component 4 through the cabinet. When the electrical components in the cabinet 5 operate and generate heat, the high-temperature air flow will flow to the low-temperature area outside the cabinet 5 and flow into the ventilation component 4 along the collecting member 83. At this time, the low-temperature air flow in the area of the collecting member 83 close to the ventilation component 4 converges with the high-temperature air flow and condenses water vapor. The collecting member 83 collects the water vapor. When the air flow outside the cabinet 5 enters the cabinet 5, the collecting member 83 adsorbs the dust in the air to reduce the dust in the cabinet 5 and perform dust-proof treatment on the cabinet 5.

[0051] The collecting member 83 is arranged in a double-layer structure. The round holes 834 formed on the surface of the inner filter screen 832 enable the extension cover 835 and the inner filter screen 832 assembly to form a collecting cavity. The extension cover 835 and the inner filter screen 832 are arranged in a horn-shaped structure, with a larger opening on the side of the cabinet body 5 to facilitate the outward export of the high-temperature air flow in the cabinet body 5, and a smaller opening on the side of the ventilation component 4. When the air flow outside the cabinet body 5 flows into the cabinet body 5 for exchange, the air flow passes through the inner filter screen 832 along the connecting ring 833 and enters the collecting cavity. At this time, the water vapor collected in the collecting cavity adsorbs the dust in the air.

[0052] When the air flow moves, it pushes the snap ring rod 851 to rotate inside the inner filter screen 832 and drives the spherical ball 853 to rotate accordingly. Since the inner filter screen 832 is arranged in a horn-shaped structure, when the air flow flows from one end of the clamping ring 831 to the connecting ring 833, the opening of the inner filter screen 832 is larger, and the air flow can quickly pass through between the spherical ball 853 and the inner filter screen 832. When the air flow flows from one end of the connecting ring 833 to the clamping ring 831, the opening of the inner filter screen 832 is smaller, and the air flow is limited by the spherical ball 853 during the flow and will diffuse to the surrounding collecting cavity, and then enter the cabinet body 5 after contacting the condensed water vapor in the collecting cavity to settle the dust, so as to achieve the purpose of dust reduction and diversion of the air flow entering the cabinet body 5.

[0053] The external cover 42 protects the collecting member 83 to prevent larger impurities from entering the collecting member 83 and causing blockage of the collecting member 83, which affects the heat dissipation effect. The inclined groove 41 provided at the top of the external cover 42 guides the rainwater to prevent rainwater accumulation on the protective cover 1, which affects the service life of the power distribution cabinet.
