To achieve these goals, the technical solution of the utility model is as follows: a kind of variable-frequency power generation unit inverter base, it is characterized in that: comprise inverter base body, the front and back of described inverter base body is respectively equipped with front installation cavity (2) and rear installation cavity (1), the mouth of described rear installation cavity (1) and front installation cavity (2) is respectively equipped with ring flange (7), the sidewall of described rear installation cavity (1) is provided with the ventilation hole communicated with the air inlet of engine wind scooper and the stay cord hole (4) of stretching out for stay cord, the center of the inner bottom surface of described rear installation cavity (1) is provided with installation shaft (6).
Adopt technique scheme, the electronic unit of inverter is arranged in front installation cavity, pulling plate assembly is contained in rear installation cavity, pulling plate cover in pulling plate assembly on the mounting shaft, then cover on front installation cavity by a plastic housing, the ring flange of rear installation cavity is contained on the air inlet of engine wind scooper, like this, be equivalent to directly inverter base is contained on the air inlet of engine wind scooper, there is following benefit: 1, under the effect of engine wind scooper internal fan, air-flow enters in rear installation cavity by the air inlet of the sidewall of rear installation cavity, be equivalent to the wind entered in engine wind scooper first all cool inverter electronic unit by force, make the cooling effect of inverter electronic unit better.2, existing pulling plate cover and inverter cover are become one, structure is simpler, and parts reduce, and manufacturing cost is lower, and it is easier to assemble.3, shorten the length of unit, make the more compact structure of unit.
In technique scheme: the degree of depth of described rear installation cavity (1) is greater than the degree of depth of front installation cavity (2).Be more convenient for installing the electronic unit of pulling plate assembly and inverter like this.
In technique scheme: the sidewall of the relative both sides of described rear installation cavity (1) is symmetrically distributed with shutter (3), each louver board of the corresponding shutter (3) of inner bottom surface of described rear installation cavity (1) is provided with a radiating ribs (5), and the two ends of described radiating ribs (5) are connected with the inner of the louvered top edge of the shutter (3) of opposite side respectively.Like this, be more conducive to entering the air-flow in rear installation cavity from shutter and cooled by the electronic unit of air channel to inverter between the radiating ribs of bottom surface, cooling effect is better.
Conveniently install, the sidewall of described rear installation cavity (1) is symmetrically arranged with two stay cord holes (4).The inner bottom surface of described front installation cavity (2) is distributed with erection column (8).
Beneficial effect: existing inverter cover and pulling plate cover become one and form inverter base by the utility model, make the cooling effect of inverter electronic unit better, parts reduce, and reduce manufacturing cost, set structure is compacter.
