Description

Technical Field

[0001] The utility model belongs to the technical field of distribution cabinets, and particularly relates to an outdoor waterproof and moisture-proof distribution cabinet. Background Technique

[0002] An outdoor distribution cabinet is an electrical equipment cabinet installed in an outdoor environment for distributing and controlling electric power. It usually has characteristics such as waterproof, dustproof, rustproof, and corrosion-resistant to adapt to relatively harsh climatic conditions and environments outdoors. Generally, electrical components such as circuit breakers, contactors, relays, fuses, and electric meters are included in the outdoor distribution cabinet for distributing, protecting, and monitoring electric power.

[0003] The specification of Chinese Patent CN214626035U discloses a high heat dissipation and energy-saving outdoor distribution cabinet, including a device main body. The device main body includes a cabinet body. An air inlet is opened at the top end of the cabinet body. A motor is fixedly installed at the top end of the cabinet body. The bottom end of the motor is movably connected with a first rotating shaft through a bearing, and the first rotating shaft extends into the cabinet body through a through groove. The outer surface of the first rotating shaft is movably connected with a transmission belt through a pulley. Both ends of the transmission belt are movably connected with a second rotating shaft through a pulley, and the top ends of the second rotating shafts are inserted into the bearings at the top end inside the cabinet body. The bottom ends of the first rotating shaft and the second rotating shaft are both fixedly installed with fan blades. By setting the device main body, cabinet body, air inlet, motor, first rotating shaft, transmission belt, second rotating shaft, control platform, and fan blades, this utility model is beneficial to cooling and dissipating heat inside the cabinet body and promoting the circulation of air inside the cabinet.

[0004] The above device adopts the technical means of cooling and dissipating heat for the distribution cabinet. However, when using the above device, for the distribution cabinet installed outdoors, in the rainy season, the environment is relatively humid, and water vapor is likely to adhere to the heat dissipation holes. If not cleaned in time, it is easy to cause water vapor to penetrate into the distribution cabinet. Moreover, there is no structure for blocking water vapor at the existing heat dissipation holes. Therefore, a new type of outdoor waterproof and moisture-proof distribution cabinet is needed to improve the above device. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides an outdoor waterproof and moisture-proof distribution cabinet, which has the advantage of waterproofing the heat dissipation holes and solves the problem that water vapor enters the interior of the distribution cabinet and causes damage due to the inability to waterproof.

[0006] To achieve the above purpose of waterproofing the heat dissipation holes, the utility model provides the following technical solution: An outdoor waterproof and moisture-proof distribution cabinet includes a distribution cabinet body. A heat dissipation port is drilled on the side end of the distribution cabinet body. An electric louver is installed on the inner wall of the heat dissipation port. A filter screen is fixedly connected to the inner wall of the heat dissipation port on the side away from the electric louver. A waterproof component is fixedly connected to the distribution cabinet body outside the heat dissipation port circle, and an adjustment component is installed on the waterproof component;

[0007] The waterproof component includes a frame fixed to the outer circle of the heat dissipation port on the main body of the power distribution cabinet.

A waterproof curtain is threaded through the drawstrings, and the bottom end of the waterproof curtain is detachably connected to the lower plate. The top end of the waterproof curtain is detachably connected to an upper plate, and the two drawstrings penetrate through the upper plate and are fixedly connected to the top wall of the frame;

[0008] The adjustment component includes a support plate fixed to the side end of the frame. A micro servo motor is fixedly connected to the support plate, and the micro servo motor is covered with a protective cover. The middle part of the inner wall of the heat dissipation port is rotatably connected with a second rotating shaft, and the output end of the micro servo motor is connected to the second rotating shaft. A first pulling rope is wound around the second rotating shaft, and one end of the first pulling rope away from the second rotating shaft is fixedly connected to the side end of the upper plate. The upper and lower parts of the inner wall of the frame on the side of the second rotating shaft are respectively rotatably connected with a fourth rotating shaft and a first rotating shaft. First belt pulleys are sleeved on both the first rotating shaft and the second rotating shaft, and the two first belt pulleys are connected by a first belt. Gears are sleeved on both the two fourth rotating shafts, and the two gears are meshed. Second belt pulleys are sleeved on both the fourth rotating shaft and the first rotating shaft below, and the two second belt pulleys are connected by a second belt. The middle part of the top wall of the frame is rotatably connected with a third rotating shaft. A second pulling rope is wound around the third rotating shaft, and one end of the second pulling rope away from the third rotating shaft is fixedly connected to the side end of the upper plate. Third belt pulleys are sleeved on both the third rotating shaft and the fourth rotating shaft above, and the two third belt pulleys are connected by a third belt.

[0009] Furthermore, the waterproof curtain is made of cotton mesh material, and the drawstrings fold and penetrate through the waterproof curtain in sequence.

[0010] Furthermore, a slot hole is drilled at the bottom end of the frame, and the lower plate is fixed to the middle part of the inner wall of the slot hole.

At this time, the electric blinds 3 are closed regularly through the time controller. The micro servo motor 601 is turned on, and the second rotating shaft 606 drives the first pull rope 603 to reel up, so that the first pull rope 603 pulls the upper plate 504 to move dependently to fold and reel the waterproof curtain 503 until it contacts and squeezes the bottom lower plate 506, thereby squeezing out the moisture absorbed by the waterproof curtain 503 to prevent excessive moisture from flowing into the heat dissipation port 2, and effectively achieving the effect of automatically waterproofing the heat dissipation port 2 on rainy days, and when the waterproof curtain 503 is squeezed and drained, the moisture can flow from the gap in the slot 502 to the outside of the distribution cabinet body 1, and the accumulated water can be prevented from flowing into the heat dissipation port 2, and when the waterproof curtain 503 is used for a long time, it can be regularly removed and replaced, and the orange can be taken out from the lower plate 506 and the upper plate 504.
