Description
Technical field
The utility model relates to alternating current generator technical field, especially a kind of sea transport refrigeration system alternating current generator.
Background technique
The alternating current generator used in refrigeration system of sea transport at present is usually vertically-mounted, the i.e. output end of motor
Upward, condensed water in the environment of refrigeration system, is easy to produce in sea transport due to alternating current generator inside motor, it is therefore, existing
There is the water hole that can generally begin to rehearse on the tail end end cap of alternating current generator under the operating condition, so that the condensed water that will be generated inside motor is discharged,
But the drainage hole is the straight hole on vertical direction, and external liquid is caused to be easy to be splashed to inside motor from straight hole, from
And motor is caused to be easy to happen damage.
Utility model content
Technical problem to be solved by the utility model is: in order to solve the friendship of refrigeration system in sea transport in the prior art
Drainage hole on its tail end end cap of galvanic electricity machine is the straight hole on vertical direction, and external liquid is caused to be easy to be splashed to from straight hole
Inside motor, and then the problem of cause motor to be easily damaged, a kind of sea transport refrigeration system alternating current generator is now provided.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of sea transport is exchanged with refrigeration system
Motor including electric machine casing and is installed on the end cap of electric machine casing tail end opening, close to electric machine casing front end on the end cap
A side end face be upper surface, there is on the upper surface of the end cap annular groove, the intermediate position of the annular groove slot bottom
Bearing chamber is upwardly extended, the tail end of shaft is located in bearing chamber in the electric machine casing, and the slot bottom of the annular groove runs through
There are inclined drainage hole, the axis of the drainage hole and the mutual bracket of the axis of end cap.
Motor inside is drained using the drainage hole that axis is obliquely installed in this programme, while the inclined draining of axis
Hole can prevent external liquid to be easily splashed to inside motor, to effectively be protected motor.
Further, the slot bottom of the annular groove from top to bottom slopes inwardly, and the upper end opening of the drainage hole is located at
Corner between the slot bottom and bearing chamber of annular groove can make motor by the way that annular groove is designed to that intermediate low edge is high
Internal condensed water converges to the intermediate position of annular groove, and is discharged from drainage hole.
Further, baffle, the lower ending opening of the baffle and drainage hole are covered at the lower ending opening of the drainage hole
Between there is gap, the baffle is fixed by screws on the lower end surface of end cap, blocked by baffle in the lower end of drainage hole
Opening can form first of protection, prevent in external liquid splash to drainage hole, and baffle and drainage hole lower ending opening it
Between gap be discharge in order not to interfere motor internal condensation water, drainage hole then constitutes second protection, prevents external sputtering
Liquid to gap location enters inside motor from drainage hole.
The beneficial effects of the utility model are: the utility model sea transport refrigeration system alternating current generator is inclined using axis
The drainage hole being tiltedly arranged drains motor inside, while the inclined drainage hole of axis can prevent external liquid from easily splashing
It is mapped to inside motor, to effectively be protected motor, effectively raises the service life of motor.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the schematic diagram of the utility model sea transport refrigeration system alternating current generator；
Fig. 2 is the partial enlargement diagram of A in Fig. 1.
In figure: 1, end cap, 1-1, annular groove, 1-2, bearing chamber, 1-3, drainage hole, 2, baffle, 3, screw, 4, gap.
Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model, direction
It can be only used for helping the description to the feature in attached drawing with referring to (for example, upper and lower, left and right, etc.).Therefore, it is not limiting
Following specific embodiments are used in property meaning processed, and are only requested by appended claims and its equivalent form to limit
The range of the theme of protection.
Embodiment 1
As shown in Figs. 1-2, a kind of sea transport refrigeration system alternating current generator, including electric machine casing and it is installed on motor casing
The end cap 1 of body tail end opening, the side end face on the end cap 1 close to electric machine casing front end are upper surface, the end cap 1
There is annular groove 1-1, the intermediate position of the annular groove 1-1 slot bottom has upwardly extended bearing chamber 1-2, described on upper surface
The tail end of shaft is located in bearing chamber 1-2 in electric machine casing, and the slot bottom of the annular groove 1-1, which runs through, inclined drainage hole 1-
The axis of 3, the drainage hole 1-3 and the mutual bracket of axis of end cap 1.
The slot bottom of the annular groove 1-1 from top to bottom slopes inwardly, and the upper end opening of the drainage hole 1-3 is located at annular
