Description

Technical Field

[0001] This invention relates to the field of power equipment, and more specifically to a power distribution cabinet. Background Technology

[0002] A distribution cabinet is a device used for centralized management and distribution of electricity, commonly found in industrial, commercial, and residential buildings. A distribution cabinet typically includes a main power distribution panel, branch lines, protection devices, control devices, and electricity metering equipment, used to distribute electricity from the power source. Distribution cabinets can distribute power from the grid or generators to different electrical devices or areas to meet the power requirements of different devices. The design and installation of distribution cabinets must comply with relevant electrical safety standards and specifications to ensure the safe and reliable operation of the power system. Currently, most distribution cabinets have flat tops, which makes them prone to snow accumulation and melting during snowfall, potentially damaging the cabinet's casing. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides a power distribution cabinet, which has the advantage of facilitating the drainage of melted snow water and preventing it from accumulating on the top of the power distribution cabinet.

[0004] A power distribution cabinet includes a top plate, five drainage channels and a water inlet pipe. The water inlet pipe is screwed to the bottom of the top plate. The five drainage channels are evenly arranged above the top plate, and the bottom of the drainage channels is provided with an inclined surface.

[0005] It also includes a support plate, a rack, a scraper, and a gear. The support plate is welded below the top plate, the rack is slidably connected inside the support plate, the scraper is welded above the rack and contacts the upper surface of the top plate, and the gear is rotatably connected to the support plate. The rack and gear are meshed and connected for transmission.

[0006] It also includes bevel gear I, blade tube, three blades and bevel gear II. Bevel gear I is rotatably connected to the support plate and connected to the gear key. The blade tube is rotatably connected below the water inlet pipe. The three blades are evenly arranged inside the blade tube. Bevel gear II is keyed to the top of the blade tube. Bevel gear I and bevel gear II are meshed and connected for transmission.

[0007] It also includes two side plates and two mounting brackets. The two side plates are welded to the bottom of the top plate, and the two mounting brackets are screwed to the corresponding side plates. Each side plate has three heat dissipation holes. Attached Figure Description

[0023] like Figure 3-4 As shown, this example can effectively prevent melted snow from accumulating on top of the electrical control cabinet.

[0024] Since the power distribution cabinet includes a top plate 101, five drainage channels 103 and a water inlet pipe 104, the water inlet pipe 104 is screwed to the bottom of the top plate 101. The five drainage channels 103 are evenly arranged above the top plate 101. The bottom of the drainage channels 103 is provided with a slope. When snowflakes fall on the top of the power distribution cabinet, the heat generated by the operation of the power components inside the power distribution cabinet can melt the snow. The melted snow water flows into the water inlet pipe 104 along the drainage channels 103, thereby preventing the melted snow water from forming an ice-snow mixture with the continuing snow. This achieves the effect of preventing the melted snow water from accumulating on the top of the power distribution cabinet.

[0025] like Figure 3-4 As shown, this example allows for the easy removal of snow from the top of the distribution cabinet using a scraper 106.

[0026] Since the distribution cabinet also includes a support plate 102, a rack 105, a scraper 106, and a gear 109, the support plate 102 is welded below the top plate 101, the rack 105 is slidably connected inside the support plate 102, the scraper 106 is welded above the rack 105 and contacts the upper surface of the top plate 101, and the gear 109 is rotatably connected to the support plate 102. The rack 105 and the gear 109 are meshed and connected, so when the gear 109 rotates, it can drive the rack 105 to move along the support plate 102, and the rack 105 can drive the scraper 106 to move forward close to the upper surface of the top plate 101. Thus, the scraper 106 can scrape away the snow on the top plate 101 and push the snow into the drainage channel 103, so that it can melt and flow into the water inlet pipe 104, thereby achieving the effect of easily scraping away the snow on the top of the distribution cabinet with the scraper 106.

[0027] like Figure 3-6 As shown, this example enables the scraper 106 to move easily when collecting snow water.

[0028] Since the distribution cabinet also includes bevel gear I 108, blade tube 202, three blades 203, and bevel gear II 204, bevel gear I 108 is rotatably connected to the support plate 102 and keyed to gear 109. Blade tube 202 is rotatably connected below water inlet pipe 104. Three blades 203 are evenly arranged inside blade tube 202. Bevel gear II 204 is keyed above blade tube 202. Bevel gear I 108 and bevel gear II 204 are meshed and connected for transmission. Melted snow water flows into blade tube 202 through water inlet pipe 104. The snow water drives the three blades 203 to rotate. The three blades 203 drive blade tube 202 and bevel gear II 204 to rotate together. Bevel gear II 204 drives bevel gear I 108 to rotate. Bevel gear I 108 drives gear 109 to rotate. Gear 109 drives rack 105 and scraper 106 to move forward, thus achieving the effect of driving scraper 106 to move when collecting snow water.

[0029] like Figure 3-6 As shown, this example can facilitate the heat dissipation of electrical equipment mounted on the mounting bracket 302.

[0030] Since the distribution cabinet also includes two side plates 301 and two mounting brackets 302, the two side plates 301 are welded to the bottom of the top plate 101, and the two mounting brackets 302 are screwed to the corresponding side plates 301. Each side plate 301 has three heat dissipation holes 303, so that the electrical equipment can be installed on the mounting brackets 302 of the two side plates 301. The positions of the heat dissipation holes 303 on the side plates 301 correspond to the mounting brackets 302, which facilitates air circulation to remove the heat of the electrical equipment, thereby achieving the effect of heat dissipation for the electrical equipment installed on the mounting brackets 302.

[0031] like Figure 5-8 As shown, this example can achieve the effect of easily preventing wind and snow from entering the heat dissipation hole 303 by using the baffle 308.

[0032] The distribution cabinet also includes a bevel gear III 205, two threaded rods 305, two sliders 306, and two baffles 308. The bevel gear III 205 is keyed to the bottom of the blade tube 202. The two threaded rods 305 are rotatably connected to their respective side plates 301. Each threaded rod 305 is keyed to a bevel gear IV 304. The two bevel gears IV 304 mesh and drive each other on both sides of the bevel gear III 205. The two sliders 306 are threaded to their respective threaded rods 305. One end of a connecting rod 307 is rotatably connected to each slider 306. The two baffles 308 are rotatably connected to their respective side plates 301. The other end of each connecting rod 307 is rotatably connected to the corresponding baffle 308, thereby enabling the blade tube 202 to drive the bevel gear III 205 to rotate, which in turn drives the two bevel gears IV 304 to rotate together. The bevel gears IV 304 then drive the threaded rod 305 to rotate together, which in turn drives the slider 306 to move outward. The slider 306 then drives the connecting rod 307 to rotate, which in turn pulls the baffle 308 downward. Thus, the two baffles 308 can respectively block the corresponding heat dissipation holes 303, thereby achieving the effect of preventing wind and snow from entering the heat dissipation holes 303.

[0033] like Figure 3-6 As shown, this example can effectively prevent the scraper 106 from moving excessively and detaching from the distribution cabinet.

[0034] Since the distribution cabinet also includes a button 107 and a slider 201, the blade tube 202 is threaded, the slider 201 is threadedly connected to the blade tube 202, the button 107 is slidably connected to the support plate 102, the slider 201 is slidably connected to the support plate 102, and the output shaft of the rotary motor is keyed to the bevel gear I 108. Thus, when the blade tube 202 rotates, it can drive the slider 201 to slide upward along the support plate 102. Thus, when the slider 201 slides to the top, it can press the button 107. Thus, the button 107 drives the rotary motor, and the rotary motor drives the bevel gear I 108 to rotate in the opposite direction. Thus, the bevel gear I 108 drives the rack 105 and the scraper 106 to move backward. Thus, the bevel gear I 108 drives the blade tube 202 and the bevel gear III 205 to rotate in the opposite direction together. Thus, the two threaded rods 305 respectively drive the two baffles 308 to retract into the side plate 301, thereby achieving the effect of preventing the scraper 106 from moving excessively and detaching from the distribution cabinet.

[0035] like Figure 3-8 As shown, this example can facilitate the cleaning of snow accumulation above baffle 308.

[0036] Since the distribution cabinet also includes two sweeping rods 309, which are rotatably connected to their respective side plates 301, and springs are welded to the sweeping rods 309 and the side plates 301, and an inclined surface is provided below the sweeping rods 309, when the baffle 308 rotates downward, the springs can push the sweeping rods 309 out of the side plates 301, and the sweeping rods 309 can push down and sweep away the snow above the baffle 308. When the rotary motor drives the bevel gear I108 to rotate in the opposite direction, the baffle 308 rotates upward and retracts into the side plates 301, and the baffle 308 can push the inclined surface below the sweeping rods 309, pushing the sweeping rods 309 back into the side plates 301, thereby achieving the effect of facilitating the cleaning of the snow accumulated above the baffle 308.

[0037] like Figure 5-10 As shown, this example demonstrates how melted snow water can be used to cool electrical control cabinets.

[0038] Since the distribution cabinet also includes a water tank 401, a water inlet pipe 402, and two heat dissipation pipes 403, the water tank 401 is screwed between two side plates 301, the water inlet pipe 402 is rotatably connected to the bottom of the vane pipe 202, and a sealing ring is provided on the water inlet pipe 402. The two heat dissipation pipes 403 are screwed above the water tank 401 and pass through the corresponding mounting brackets 302 respectively. A water pump is provided in the water tank 401, so the melted snow water flows into the water inlet pipe 402 through the vane pipe 202. The sealing ring on the water inlet pipe 402 seals the gap between the vane pipe 202 and the water inlet pipe 402, so the snow water flows into the water tank 401 from the water inlet pipe 402. The water pump then guides the melted snow water into the heat dissipation pipes 403, so the heat dissipation pipes 403 can cool the electrical components on the mounting brackets 302, thus achieving the effect of facilitating the use of melted snow water for cooling the distribution cabinet.

[0039] like Figure 3-10 As shown, this example can facilitate faster melting of snow on top of the distribution cabinet.

[0040] Since the distribution cabinet also includes a bend pipe 404, which is welded above the two heat dissipation pipes 403 and is located below the top plate 101, the cooling water in the heat dissipation pipes 403 absorbs the heat of the power components and flows into the bend pipe 404. The bend pipe 404 then heats and melts the snow falling above the top plate 101, and the snow water flows into the water inlet pipe 104 along the drainage channel 105, thereby achieving the effect of accelerating the melting of the snow falling on the top of the distribution cabinet.

[0041] like Figure 9-10 As shown, this example achieves the effect of easily fixing the water tank 401 into the concrete on the ground.

[0042] Since the distribution cabinet also includes four plug plates 405, which are welded to the bottom of the water tank 401, each plug plate 405 is provided with four horizontal plates 406, so that the four plug plates 405 can be inserted into the concrete to fix the water tank 401 in the concrete on the ground. After the concrete solidifies, the multiple horizontal plates 406 can firmly fix the four plug plates 405 in the concrete, thereby achieving the effect of easily fixing the water tank 401 in the concrete on the ground.
