Abstract
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.
Description
Affiliated technical field
The present invention is a kind of mode of structure that is used for the water outlet and the outlet of built-in submerged motor pump, especially in coal mine, use, the mode of connection that need to change motor coil adapts to the water outlet of flame-proof mine built-in submerged motor pump of supply voltage conversion and the mode of structure of outlet, belongs to universal machine product manufacturing technology field.
Background technique
At present, built-in submerged motor pump its manufacturing for convenience and installing and using, the position majority of its water outlet and outlet above the unit be the unit overcoat on cover, as shown in Figure 1.Fig. 1 is the Figure of description of 200420015632.7 patents, its major character is, outlet and water outlet are on the same lid and the shaft axis of outlet not on the shaft axis at unit, its major defect be the motor loam cake outlet shaft axis and unit overcoat loam cake the outlet shaft axis to overlap manufacturability bad, and the terminal box that can change the motor coil mode of connection is not set, so can not adapt to the difference of 660 volts or 1140 volts supply voltages in the mode of connection of the on-the-spot conversion motor coil of user.Present built-in submerged motor pump also has water outlet up, outlet below, as shown in Figure 2.Fig. 2 is the Figure of description of 200620084577.6 patents, and its major defect is to be difficult to the terminal box that can change the motor coil mode of connection is set, and just can not use if user's supply voltage changes.Terminal box is also arranged at present above unit, water outlet is at the unit side, as shown in Figure 3, this built-in submerged motor pump manufacturing ratio is easier to, and the conversion motor coil mode of connection adapts to different supply voltages easily, but defective is that the radial dimension of unit is too big, installs and uses inconvenience in narrow mine.
Summary of the invention
In order to overcome the deficiency of existing built-in submerged motor pump, the invention provides a kind of mode of structure of water outlet and outlet of built-in submerged motor pump, the position of its water outlet and outlet is all above unit, and a terminal box that can change the motor coil mode of connection is arranged, not only make, install very convenient, and can be at the user scene very easily the conversion motor coil mode of connection adapt to 660 volts or 1140 volts of supply voltages.
The technical solution adopted for the present invention to solve the technical problems is:
On the unit top of built-in submerged motor pump a terminal box is set, 6 wiring terminals are arranged in the terminal box, be used to change the mode of connection of motor coil, there is the seam of cooperation the bottom of terminal box with electric machine casing, seam is concentric with the unit shaft axis, the top of terminal box is stamped with terminal box and is cooperated seam, seam is concentric with the unit shaft axis, the elastic cable paper of unit is drawn from the top of connector cover, the outlet pipe of unit and the as a whole part of unit loam cake, communicating with cooling cavity between outlet pipe bottom and unit overcoat and the electric machine casing, the outlet pipe upper flange is to unit shaft axis biasing, and the axis projection of outlet pipe upper flange is fully in the axis projection of unit loam cake, and there is a circular hole centre of unit loam cake, the internal diameter of this circular hole is that radial clearance cooperates with the terminal box external diameter, and adopts the O-ring seals sealing.
When the mains voltage variations at user scene,, change the mode of connection and just can adapt to and has used as long as open connector cover.Because the outlet pipe upper flange is general all much smaller than the diameter of unit loam cake, so the outlet pipe upper flange of biasing can not influence the switching of connector cover, again because the axis projection of outlet pipe upper flange fully in the axis projection of unit loam cake, so the radial dimension of unit is smaller, be convenient in narrow mine, install and use.
The invention has the beneficial effects as follows, not only adapt to the conversion of supply voltage, and be convenient in narrow mine, install and use.

Embodiment
Embodiment illustrated in fig. 4 is a flame-proof mine built-in submerged motor pump, and Fig. 5 is the partial view that this embodiment innovates part.In Fig. 4 and Fig. 5, terminal box 12 is positioned at unit top, in 6 wiring terminals 13 are arranged, be used to change the mode of connection of motor coil 7, there is the seam of cooperation 6 bottom of terminal box with electric machine casing 16, seam 6 is concentric with unit shaft axis 8, there is the seam of cooperation 5 on the top of terminal box with connector cover 2, seam 5 is concentric with the unit shaft axis, the elastic cable paper 1 of unit is drawn from the top of connector cover, the outlet pipe 10 of unit and unit loam cake 3 as a whole parts, the outlet pipe bottom communicates with cooling chamber 14 between unit overcoat 15 and the electric machine casing 16, and outlet pipe upper flange 9 is setovered to the unit shaft axis, the axis projection of outlet pipe upper flange is fully in the axis projection of unit loam cake, and there is a circular hole 4 centre of unit loam cake, and the internal diameter of circular hole 4 is that radial clearance cooperates with the terminal box external diameter, and adopts O-ring seals 11 sealings.
When the mains voltage variations at user scene, as long as open connector cover 2, the mode of connection that changes 6 wiring terminals 13 just can adapt to have been used, and the elastic cable paper 1 of unit is drawn from the top of connector cover, and the feed cable of also being convenient in the mine connects up.Because outlet pipe upper flange 9 is general all much smaller than the diameter of unit loam cake, so the outlet pipe upper flange of biasing can not influence the switching of connector cover, again because the axis projection of outlet pipe upper flange fully in the axis projection of unit loam cake, so the radial dimension of unit is smaller, be convenient in narrow mine, install and use.
When unit was installed and used in mine, outlet pipe upper flange 9 was connected with rising pipe, as can be seen from Figure 4, even this embodiment is connected with rising pipe, did not also influence and opened connector cover 2 and change the mode of connection.
