Description of the embodiments

The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making clear and defining the scope of the present utility model.

As shown in fig. 1 to 9, the motor 1 with the composite sealing structure comprises a housing 2, a wiring opening 21 is formed at the top of the housing 2, a detachable junction box 3 is formed at the top of the housing 2, a pair of butt openings 31 is formed at the bottom of the junction box 3, the butt openings 31 are matched with the wiring opening 21, a cover plate 4 is arranged on the junction box 3, and a junction box sealing gasket 5 is arranged between the cover plate 4 and the junction box 3.

The four corners of the cover plate 4 are respectively provided with a cover plate fixing hole 42.

A terminal plate 6 and a terminal seal seat 7 are disposed in the terminal box 3, and the terminal seal seat 7 is matched with the butt joint opening 31.

The wire sealing seat 7 comprises a plate-shaped base plate 71, and three tubular high-voltage wire bushings 72 and one tubular low-voltage wire bushing 73 are arranged on the base plate 71.

The terminal box gasket 5 and the terminal box seat 7 are made of flexible materials. Preferably, both the terminal block gasket 5 and the terminal block seal seat 7 are made of rubber.

The operation of the motor 1 with the composite seal structure will be described below.

As shown in fig. 2, during installation, the three-phase high-voltage cable 22 is led out of the connection opening 21 upwards, the three-phase high-voltage cable 22 then passes through the butt-joint opening 31, and finally out of the high-voltage bushing 72 of the connection sealing seat 7. In the same way, the low-voltage cable is led out of the low-voltage cable bushing 73 of the wire sealing seat 7.

The inside diameter of the high-voltage bushing 72 is slightly smaller than the outside diameter of the three-phase high-voltage cable 22, and the inside diameter of the low-voltage bushing 73 is slightly smaller than the outside diameter of the low-voltage cable. Thus, after the wire-guiding operation is completed, the three-phase high-voltage cable 22 and the low-voltage cable cannot easily fall off from the wire sealing seat 7.

Then, the wire sealing seat 7 is injected with glue, so that the gap between the wire sealing seat 7 and the butt joint opening 31 is completely sealed.

Then, the junction box gasket 5 and the cover plate 4 are mounted on the junction box 3. Finally, the cover plate 4 is locked by means of screws.

The junction box gasket 5 plays a role of heat resistance, and prevents condensed water from being generated on the cover plate 4 and dropping onto the underlying junction plate. The wiring sealing seat 7 effectively isolates the shell 2 from the junction box 3, hot air in the shell 2 cannot enter the inner wall of the junction box 3, and the generation of condensed water is further reduced.

Because the whole junction box 3 is double and sealed through the junction box sealing gasket 5 and the junction box sealing seat 7, the generation of condensed water caused by the generation of hot air in the junction box 3 is effectively avoided, and the electrical safety of the motor is improved.

Without being limited thereto, any changes or substitutions that are not contemplated by the inventors are intended to be included within the scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope defined by the claims.
