Abstract
The utility model relates to the mechanical technology field, relates to a stator used for a motor and especially relates to a stator shell of a water wheel generator. The stator shell comprises a cylinder-shaped body. The stator shell is characterized in that an inner wall of the body is provided with several separating layers, wherein the separating layers are uniformly distributed and can separate a stator sheet from the body; several through holes are arranged between the separating layers and the body; a fixing assembly which can fix the stator sheet is arranged among the separating layers. The stator shell has the advantages that because of the through holes, heat dissipation is performed conveniently when the stator works so that a poor heat dissipation effect during long working time is avoided; a triangle separation block can fix the stator sheet and strengthen a rigidity of the whole shell.
Description
Technical field
The utility model relates to field of mechanical technique, about a kind of for the stator on motor, especially about a kind of stator casing of hydraulic generator.
Background technology
When hydraulic generator, refer to taking the hydraulic turbine as prime mover, water can be converted into the generator of electric energy.When the current process hydraulic turbine, can convert water to mechanical energy, the rotating shaft of the hydraulic turbine drives again the rotor of generator, converts mechanical energy to electric energy and exports, and is the main dynamics equipment that hydroelectric station produces electric energy.
Stator is the actionless part of motor.Stator is made up of stator core, stator winding and support three parts.The Main Function of stator is the rotating magnetic field that line rod cutting rotor produces, and the line rod cutting that to be rotating magnetic field be fixed of the Main Function of rotor produces (output) electric current by line rod.The stator casing of general motor is only the effect of playing protection fixed stator internal structure, but in some special fields, is obviously inadequate.Such as, in the time that hydraulic generator is worked, because its power is larger, longevity of service, the temperature of generation is higher, and general stator casing can not play good thermolysis, especially at stator in machine hole, Air Flow is few, and service time, long rigidity was easily influenced, and the time has been grown easy appearance and damaged.
Utility model content
The purpose of this utility model is for the problems referred to above, and a kind of stator casing of rational in infrastructure, simple, good heat dissipation effect is provided.
For achieving the above object, the utility model has adopted following technical proposal: a kind of stator casing of hydraulic generator, comprise cylinder-shaped body, it is characterized in that, described inner body wall is provided with several and is uniformly distributed, the separator that can play the isolation of stator piece and body, is provided with several through holes between described separator and body, between separator, be provided with can fixed stator sheet fixation kit.
In the stator casing of above-mentioned a kind of hydraulic generator, described separator is the triangle spacing block being fixed by welding in inner body wall, and described triangle spacing block drift angle is rounding, and the cross section equilateral triangle of triangle spacing block.
In the stator casing of above-mentioned a kind of hydraulic generator, described fixation kit comprises the horizontal fitting that two ends are fixedly connected with adjacent triangle spacing block respectively, and the keeper that can be connected with stator piece.
In the stator casing of above-mentioned a kind of hydraulic generator, described through hole is equilateral triangle.
Compared with prior art, the utility model has the advantage of: heat radiation when through hole is convenient to stator work, avoid its longevity of service to cause radiating effect bad; Triangle spacing block not only can play fixing effect, and has strengthened the rigidity of whole housing.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structure partial schematic diagram of utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, a kind of stator casing of hydraulic generator, comprise cylinder-shaped body 1, described inner body wall is provided with several and is uniformly distributed, can play the separator 2 of stator piece and body isolation, separator is the triangle spacing block 3 being fixed by welding in inner body wall, and described triangle spacing block drift angle is rounding, and the cross section equilateral triangle of triangle spacing block.Triangle spacing block drift angle can embed in stator, plays location stator piece, increases area of dissipation.Between described separator and body, be provided with several through holes 4, described through hole is equilateral triangle.Described separator is also realized by V-type muscle conventionally.Between separator, be provided with can fixed stator sheet fixation kit.Described fixation kit comprises the horizontal fitting 5 that two ends are fixedly connected with adjacent triangle spacing block respectively, and the keeper 6 that can be connected with stator piece.Can realize stator piece, body, separator by horizontal fitting and keeper integrated, realize integrally-built compactness.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
