Description

Technical Field

[0001] The utility model belongs to the technical field of high and low voltage distribution cabinets, and in particular relates to a high and low voltage distribution cabinet with high-speed ventilation. Background Art

[0002] High and low voltage distribution cabinets are distribution and control equipment used in power systems. They are usually composed of a high voltage part and a low voltage part. The high voltage part mainly includes high voltage switchgear, which is used to receive high voltage electric energy transmitted by the transmission line and distribute it to different low voltage circuits.

[0003] Publication No. CN217741045U discloses a high and low voltage distribution cabinet. In view of the existing distribution cabinet, electrical components are usually installed in a box, and each electrical component is connected by wires. When maintaining the distribution cabinet, since the outer shell of the distribution cabinet is an inseparable box, it only has an openable and closable movable door, the maintenance personnel's vision or operation is obstructed, which causes great inconvenience for the maintenance of the distribution cabinet. By removing the protective shell and rotating the support plate to a suitable angle, the maintenance personnel have a clearer and wider field of vision when observing the arrangement of electrical components and wires in the distribution cabinet, and can clearly see the direction of wires on different electrical components. In addition, during the maintenance operation, there is no box of the distribution cabinet to block the maintenance operation, and the maintenance operation is more convenient.

[0004] However, during the use of the high and low voltage distribution cabinet, the internal air circulation is completely through the heat dissipation port, so that the air circulates on its own, and the ventilation effect is poor and the heat dissipation effect is not good. At the same time, the sand and dust generated in the outdoor environment is directly blown into the distribution cabinet, affecting the distribution cabinet. For the distribution cabinet equipped with a filter, the sand and dust will clog the filter and affect the use of the distribution cabinet. Utility Model Content

[0005] The utility model provides a high- and low-voltage power distribution cabinet with high-speed ventilation, aiming to solve the above-mentioned problems.

[0006] The utility model is implemented in this way. The utility model provides the following technical solutions: a high-speed ventilated high and low voltage power distribution cabinet, comprising a power distribution cabinet body, wherein a ventilation and heat dissipation mechanism is arranged inside the power distribution cabinet body;

[0007] The ventilation and heat dissipation mechanism includes an exhaust duct, which is installed inside the distribution cabinet. The top of the exhaust duct passes through the distribution cabinet and extends to the top of the distribution cabinet. An exhaust fan is installed inside the exhaust duct. A dustproof net is installed inside the exhaust duct near the top of the exhaust fan. Dustproof net sleeves are fixedly connected to both sides of the inner wall of the distribution cabinet, one side of the dustproof net sleeve is connected to a rotating shaft, one end of the rotating shaft is fixedly connected to a rotating fan blade, and the other end of the rotating shaft is fixedly connected to a rotating scraper on the outside, and a fixed sleeve is provided on the outside of the dustproof net sleeve, and one end of the fixed sleeve is fixedly connected to one side of the distribution cabinet.

[0008] In a preferred embodiment, the number of the dustproof mesh sleeves is set to two, and one end of the two dustproof mesh sleeves passes through the power distribution cabinet and extends to the outside of the power distribution cabinet.

[0009] In a preferred embodiment, the rotating shaft is rotatably connected to the dustproof mesh sleeve, one end of the rotating shaft passes through the dustproof mesh sleeve and extends to one side of the dustproof mesh sleeve, and the rotating scraper is slidably connected to the outer surface of the dustproof mesh sleeve.

[0010] In a preferred embodiment, a fixed bottom plate is fixedly connected to the bottom of the distribution cabinet, a rainwater collection mechanism is arranged on the top of the distribution cabinet, the rainwater collection mechanism includes a fixed baffle, the fixed baffle is installed on the top of the distribution cabinet, and a plurality of support rods are fixedly connected between the fixed baffle and the distribution cabinet.

[0011] In a preferred embodiment, a through groove is provided on the top surface of the fixed baffle, an inner cavity is provided inside the fixed baffle, and connecting water pipes are connected to both sides of the fixed baffle.

[0012] In a preferred embodiment, a hot water exchange tank is fixedly connected to the bottom of one end of the connecting water pipe, and the hot water exchange tank is fixed on one side of the power distribution cabinet. One end of the connecting water pipe passes through the fixed baffle and extends to the inner cavity, and the bottom of the other end of the connecting water pipe passes through the hot water exchange tank and extends to the inside of the hot water exchange tank.

[0013] In a preferred embodiment, two heat exchange pipes are fixedly connected between the bottom of the heat exchange water tank and the fixed bottom plate, and a plurality of heat exchange connecting pipes are fixedly connected between the two heat exchange water pipes.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. By setting a ventilation and heat dissipation mechanism, the exhaust fan is started to discharge the hot air flow gathered above the inside of the distribution cabinet. Due to the pressure, the cold air from the outside enters the inside of the distribution cabinet. The cold air continuously enters and the hot air flow is continuously discharged for high-speed ventilation and heat dissipation. At the same time, the cold air entering will drive the rotating fan blades to rotate, thereby rotating the rotating shaft and the rotating scraper to rotate, which is convenient for cleaning the dust net. Compared with the prior art, the hot air flow is discharged from the exhaust pipe through the exhaust fan, and the cold air enters through the dust net to ensure the ventilation and heat dissipation effect of the distribution cabinet. At the same time, the cold air entering drives the rotating fan blades to rotate, further improving the ventilation speed and heat dissipation efficiency. At the same time, the rotating fan blades drive the rotating shaft and the rotating scraper to rotate, so that the rotating scraper cleans the dust net to prevent the dust net from being blocked, further ensuring the ventilation and heat dissipation effect.

[0016] 2. By setting up a rainwater collection mechanism, rainwater enters the inner cavity through the through groove on the surface of the fixed baffle, and then enters the heat exchange water tank through the connecting water pipe, and the distribution cabinet is heat exchanged. At the same time, the water in the heat exchange connecting pipe and the heat exchange water pipe will also exchange heat with the distribution cabinet, so that the heat is transferred to the water, achieving the effect of cooling and dissipating the heat of the distribution cabinet, and at the same time, it is more energy-saving and environmentally friendly.

One end of the fixed sleeve 9 is fixedly connected to one side of the distribution cabinet 1.

[0026] As attached Figure 1-4 As shown, the number of dustproof mesh sleeves 5 is set to two, one end of the two dustproof mesh sleeves 5 passes through the distribution cabinet 1 and extends to the outside of the distribution cabinet 1, the rotating shaft 6 is rotatably connected to the dustproof mesh sleeve 5, one end of the rotating shaft 6 passes through the dustproof mesh sleeve 5 and extends to one side of the dustproof mesh sleeve 5, and the rotating scraper 8 is slidably connected to the outer surface of the dustproof mesh sleeve 5, so that the rotating scraper 8 can move outside the dustproof mesh sleeve 5 to clean it.

[0027] As attached Figure 1-3 As shown, a fixed bottom plate 10 is fixedly connected to the bottom of the distribution cabinet 1, and a rainwater collecting mechanism is arranged on the top of the distribution cabinet 1. The rainwater collecting mechanism includes a fixed baffle 11, which is installed on the top of the distribution cabinet 1. A plurality of support rods 12 are fixedly connected between the fixed baffle 11 and the distribution cabinet 1. A through groove 13 is provided on the top surface of the fixed baffle 11, an inner cavity 14 is provided inside the fixed baffle 11, and connecting water pipes 15 are connected to both sides of the fixed baffle 11 to facilitate the collection of rainwater.
