Problems solved by technology
The invention provides an upper water and wire outlet structure of a built-in submerged motor pump. In the structure, a wiring box is arranged on the upper part of a machine set to change the wiring model of a motor coil, a cable of the machine set is led out from the upper part of the wiring box, the water outlet pipe and upper cover of the machine set are made an integrated part, the lower part of the water outlet pipe is communicated with a cooling cavity between an outer sleeve of the machine set and a shell of a motor, the flange on the upper part of the water outlet pipe deflects toward the axis of the machine set, a round hole is formed in the center of the upper cover of the machine set, the inside diameter of the round hole and the outside diameter of the wiring box are in radial clearance fit, and an O-shaped sealing ring is used for sealing. The structure has the advantages that: the wiring model of the motor coil can be conveniently changed on a user site to make the built-in submerged motor pump adapts to a power supply voltage of 660 to 1,140 volts; and the radial size of the machine set is small, so the machine site can be arranged and used in a narrow mine conveniently.
