Description

Technical Field

[0001] This utility model relates to the field of distribution box technology, and in particular to a distribution box cabinet with fireproof function. Background Technology

[0002] A distribution box cabinet is a device used in a power system to distribute, control, and protect electrical energy. It typically consists of a metal cabinet, switchgear, measuring instruments, protection devices, and auxiliary equipment. It is widely used in industrial, commercial, and residential areas to receive power from upstream sources and distribute it to various electrical devices, ensuring the safe and reliable operation of the power system.

[0003] In existing technologies, after prolonged use, the heat generated by the internal electronic components of distribution boxes and cabinets is difficult to dissipate effectively, leading to excessively high temperatures. This can easily cause damage to electronic components and aging of cables, which may in turn cause fires. Although ventilation openings equipped with fans have been used to reduce overheating, the filters are prone to dust accumulation, affecting heat dissipation, and require regular manual cleaning, increasing maintenance workload. Therefore, there is an urgent need to develop a distribution box and cabinet with fireproof functions that can effectively solve the heat dissipation problem. Utility Model Content

[0004] One objective of this invention is to provide a fireproof distribution box cabinet. This invention addresses the problem mentioned in the background that, in the prior art, after prolonged use, the heat generated by the internal electronic components of the distribution box cabinet is difficult to dissipate effectively, leading to excessively high temperatures. This can easily cause damage to electronic components and aging of cables, potentially resulting in flames and fires. Although ventilation openings equipped with fans have been used to reduce overheating, the filters are prone to dust accumulation, affecting heat dissipation, and require regular manual cleaning, increasing maintenance workload.

[0005] A fireproof distribution box cabinet according to an embodiment of the present utility model includes:

[0006] The power distribution cabinet assembly includes a cabinet body and a cabinet door. A fireproof inner box is fixedly installed inside the cabinet body. Air outlet ducts are symmetrically fixed on both sides of the fireproof inner box. A filter screen is fixed to one end of the upper air outlet duct by bolts. A cleaning mechanism for cleaning dust from the surface of the filter screen is installed on the outside of the cabinet body.

[0007] A heat dissipation component is installed at the bottom of the cabinet in the power distribution cabinet assembly to achieve rapid cooling of the power distribution box. The heat dissipation component includes a base and a coolant tank. A water tank, a circulating pump and a refrigeration device are fixedly installed inside the base. The coolant tank is located between the cabinet and the fireproof inner box. A delivery pipe connects the water tank, the circulating pump and the coolant tank. A cooling fan is fixed to one end of the lower air outlet by bolts.

[0008] The cleaning mechanism includes a guide plate and a second rotating seat. A limiting slide rod is movably installed inside the guide plate. A cleaning brush that fits against the surface of the filter screen is fixedly installed at the bottom of the limiting slide rod. A first rotating seat is fixedly installed on one side of the cleaning brush. A curved rod is fixedly installed between the first rotating seat and the second rotating seat. The second rotating seat is fixedly installed on the outside of the cabinet door.

[0009] Preferably, the cabinet door is hinged to the cabinet body for rotation, and a door handle is fixedly installed on one side of the cabinet door.

[0010] Preferably, the interior of the cabinet is provided with a fireproof and heat-insulating layer, which is made of ceramic fiber.

[0011] Preferably, the fireproof inner box is made of stainless steel.

[0012] Preferably, the air outlet duct extends through the interior of the cabinet.

[0013] Preferably, a smoke sensor and a temperature sensor are fixedly installed at the upper part of the interior of the fireproof inner box, and a buzzer and an alarm light are fixedly installed on the top of the cabinet.

[0014] Preferably, a water injection pipe is fixedly installed on one side of the water tank, penetrating the interior of the base.

[0015] Preferably, a slag guide plate is provided below the filter screen, and the slag guide plate is fixedly installed at the lower end of the air outlet duct.

[0016] The beneficial effects of this utility model are:

[0017] This invention effectively avoids the problem of heat dissipation difficulties caused by prolonged use of electronic components inside distribution boxes and cabinets in existing technologies through its heat dissipation components. The fireproof inner box, made of stainless steel, possesses excellent fire resistance and high-temperature resistance, effectively isolating flames and preventing the spread of fire in the event of a fire. Smoke and temperature sensors inside the fireproof inner box monitor the internal environment in real time. Upon detecting smoke or abnormal temperature, a buzzer and alarm light will immediately sound, alerting staff to take timely action. Furthermore, the water tank within the heat dissipation components cools the water through a refrigeration system. The coolant is then transported to a coolant reservoir via a circulating pump and delivery pipe. Located between the cabinet body and the fireproof inner box, the coolant reservoir effectively absorbs heat from the cabinet. A cooling fan delivers the cool air generated between the cabinet body and the fireproof inner box into the cabinet through an exhaust duct, further reducing the internal temperature. Finally, the hot and cold air alternate before being exhausted through the upper exhaust duct. This dual heat dissipation mechanism ensures stable internal temperature of the distribution box and cabinet, preventing the risk of fire caused by overheating.

[0018] This invention effectively prevents dust accumulation on the filter screen from affecting heat dissipation through its cleaning mechanism. When the cabinet door is opened or closed, the second rotating seat drives the crank rod to move. The crank rod, through the first rotating seat, drives the cleaning brush to slide along the limiting slide rod inside the guide plate. The cleaning brush adheres to the surface of the filter screen, effectively removing dust and debris. The guide plate located below the filter screen guides the dust and debris swept off by the cleaning brush to the lower end of the air outlet, preventing dust from re-entering the cabinet. This cleaning mechanism ensures the filter screen remains unobstructed, improves heat dissipation, and reduces heat dissipation problems caused by dust accumulation. Attached Figure Description
