Abstract

The utility model discloses a motor bedplate convenient for draining water. The motor bedplate comprises a bedplate main body, a water drainage tank axially extending along the bedplate main body is arranged on the inner bottom wall of the bedplate main body, water drainage holes are respectively arranged at two ends of the water drainage tank, and water drainage plugs are installed in the water drainage holes. Due to the fact that the water drainage tank is positioned on the inner bottom wall of the bedplate main body, accumulated water in a motor can flow into a water drainage tank and is drained out through the water drainage plugs at two ends of the water drainage tank, insulation performance of motor coils is improved, faults of short circuit and the like caused by reducing insulation performance of the coils on the motor can be avoided. Because of the water drainage tank, line distribution of outgoing lines of internal elements of the motor such as a brake, a bearing temperature measurement device, a winding temperature measurement device and a heating device is facilitated. Outgoing lines of the internal elements of the motor can be led out from the inside of the motor to a connecting box along the water drainage tank, and abrasion of the outgoing lines caused by externally leading outgoing lines is avoided.

Description

Be convenient to the motor bed-plate of draining

Technical field

The utility model relates to electric motors, relates in particular to a kind of motor bed-plate of being convenient to draining.

Background technology

Because the application of motor is more extensive; Motor can use under various environment; If the environment for use of motor is abominable, such as if there was dampness in the air or meet with rainwater weather, motor interior can produce ponding; If the temperature difference of environment for use is bigger, motor interior just might produce condensed water.The appearance of above-mentioned condition can make the motor insulation reduce and then make motor produce short trouble such as phase fault and ground short circuit etc.; Especially phase fault; Because short circuit current is bigger during fault, the motor winding coil burns, and will cause than large economy and lose.

Summary of the invention

The utility model technical problem to be solved is: a kind of motor bed-plate of being convenient to draining is provided, to discharge the ponding of motor interior, improves the overall performance of motor.

For solving the problems of the technologies described above; The technical scheme of the utility model is: the motor bed-plate of being convenient to draining; Comprise machine base body; The interior diapire of said machine base body is provided with along the axially extended rhone of said machine base body, and the two ends of said rhone are respectively equipped with osculum, in the said osculum drain plug are installed.

As a kind of improvement, the bottom of said rhone is an arc.

Owing to adopted technique scheme; The beneficial effect of the utility model is: owing on the interior diapire of machine base body, be provided with rhone; Ponding in the motor flows in the rhone; And discharge through the drain plug that the rhone two ends are provided with, improved the insulation property of motor winding, avoided motor short trouble etc. to occur because of the insulating properties of coil reduces; Owing to be provided with rhone; Made things convenient for the cabling of lead-out wires such as motor interior components and parts such as brake, measuring temperature of bearing device, winding temperature measurement device and heater; Make the lead-out wire of motor interior components and parts cause terminal box along rhone, avoided lead-out wire to cause the lead-out wire wearing and tearing from outside lead from motor interior.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 is along the cross-sectional schematic of G-G direction among Fig. 1;

Among the figure: the 1-machine base body; The 2-rhone; The 21-osculum; The 3-drain plug.

Embodiment

Shown in Fig. 1 and Fig. 2 are common; Be convenient to the motor bed-plate of draining, comprise machine base body 1, the interior diapire of machine base body 1 is provided with along machine base body 1 axially extended rhone 2; The two ends of rhone 2 are respectively equipped with osculum 21; Osculum 21 is a through hole, and drain plug 3 is installed in the osculum 21, is in communication with the outside on the drain plug 3 ponding is discharged.

For current are compiled, the bottom of rhone 2 is an arc.

When motor interior has ponding; Flowing water can be assembled toward machine base body 1 bottom; Rhone is established 2 put the ponding of in machine base body 1, being convenient to collect motor interior on the diapire; The ponding of assembling in the rhone 2 is discharged to the motor outside through drain plug 3, and dry to keep motor interior, each components and parts insulating properties is not influenced by ponding.

Owing on the interior diapire of machine base body, be provided with rhone; Ponding in the motor flows in the rhone; And discharge through the drain plug that the rhone two ends are provided with, improved the insulation property of motor winding, avoided motor to reduce faults such as short circuit occur because of the insulating properties of coil; Owing to be provided with rhone; Made things convenient for the cabling of lead-out wires such as motor interior components and parts such as brake, measuring temperature of bearing device, winding temperature measurement device and heater; Make the lead-out wire of motor interior components and parts cause terminal box along rhone, avoided lead-out wire to cause the lead-out wire wearing and tearing from outside lead from motor interior.

More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection range to be defined by appending claims and equivalent thereof.

Claims

1. be convenient to the motor bed-plate of draining; Comprise machine base body; It is characterized in that: the interior diapire of said machine base body is provided with along the axially extended rhone of said machine base body, and the two ends of said rhone are respectively equipped with osculum, in the said osculum drain plug are installed.

2. the motor bed-plate of being convenient to draining as claimed in claim 1 is characterized in that: the bottom of said rhone is an arc.
