Problems solved by technology

[0003] When the power distribution cabinet is used in water conservancy projects, it is sometimes necessary to sink the power distribution cabinet into the water. However, the weight of the power distribution cabinet is usually large, and it is difficult to salvage it out of the water when it needs to be repaired and maintained later. A certain amount of heat will also be generated during the process. After the traditional power distribution cabinet sinks into the water, the contact area with the water is limited, and its overall heat dissipation capacity is average.

Abstract

The invention discloses a power distribution cabinet for water conservancy equipment, and the power distribution cabinet comprises a cylindrical housing, the interior of the cylindrical housing is recessed inwards in the axial direction of the cylindrical housing to form a channel, the channel penetrates the left and right ends of the cylindrical housing, and a closed cavity is formed between theinner wall of the channel and the outer wall of the cylindrical housing in a surrounding manner. A water pump blade is rotatably connected in the channel, the water pump blade is in transmission connection with a driving motor through a transmission shaft, the outer wall of the columnar shell and the inner wall of the channel can make contact with water, the overall heat dissipation area is relatively large, meanwhile, water in the channel can continuously flow under driving of the water pump blade, water circulation is accelerated, and heat is brought away. A liquid carbon dioxide tank and astorage bin are fixed to the outer wall of the columnar shell, an air bag is bound in the storage bin, when the columnar shell needs to be fished and overhauled, carbon dioxide gas can be released into the air bag through the liquid carbon dioxide tank so that the air bag can be filled with the carbon dioxide gas, buoyancy can be generated, and therefore the heavy columnar shell can be fished outconveniently.

Description

technical field [0001] The invention relates to the field of power distribution cabinets, in particular to a power distribution cabinet for water conservancy equipment. Background technique [0002] Power distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets, and are the final equipment of the power distribution system. The power distribution cabinet is a general term for the motor control center. The power distribution cabinet is used in the occasions where the load is relatively scattered and there are few circuits; the motor control center is used in the occasions where the load is concentrated and there are many circuits. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearest load. This level of equipment shall provide protection, monitoring and control of the load. [0003] When the power distribution cabinet is used in water conservanc...
