In first half-shell 13, with 13 integral installation of first half-shell when installation, it is more convenient to install.When needing to motor 11 or leaf
When wheel 14 such as performs overhauling and maintenance, replaces at the operations, only need to by first half-shell 13 together with motor 11, impeller 14 it is whole and the second half
It is disassembled on shell 15.The second spiral case 15 need not be dismantled, mounting plate 4 need not be also dismantled, whole maintainability is more preferable.
For embodiment two as shown in Fig. 2, being related to a kind of spiral case wind turbine, which includes spiral case 84, impeller 83, motor
81.Spiral case 84 is used to accommodate the impeller 83, including at least one side wall and the peripheral wall for surrounding the impeller, and is formed as phase
For the tubular that the radius of electrical axis becomes larger along the direction of rotation of impeller 83,84 inside of spiral case forms air-supply access, from institute
The peripheral wall for stating the larger side of the radius relative to electrical axis of spiral case 84 extends along the tangent direction, described by making
Impeller 83 rotates, to convey air to the air-supply access.Motor 81 is mounted in the one side wall of spiral case 84, the rotation of motor 81
Shaft 112 pass through spiral case 84 the one side wall be connected with the impeller 83 inside spiral case 84 and can impeller 83 rotation,
The other side opposite with the installation one side wall of motor of spiral case is equipped with spiral case air inlet.
As a preferred solution, as shown in Fig. 2, for the ease of manufacturing and installing, spiral case 84 includes 841 He of spiral case cover
Spiral case bottom plate 842, spiral case cover 841 are formed as the tubular to become larger along the direction of rotation of impeller 83 relative to the radius of electrical axis,
There are one the peripheral wall of the side wall for installing motor 81 and the outer rim encirclement impeller set on side wall, the preferred peripheral wall and institutes for tool
Side wall integrated molding is stated, spiral case cover 841 is open design in the other side opposite with the installation side of motor 81, is conducive in this way
Motor 81 and impeller 83 are installed.Spiral case bottom plate 842 is used in the open side of other side closing spiral case cover 841, spiral case bottom plate
842 are equipped with air inlet as spiral case air inlet above-mentioned, and spiral case cover 841 is in the side of separate motor 81 and spiral case bottom plate 842
It is connected, and makes the air inlet of impeller 83 opposite with the air inlet of spiral case bottom plate 842, the same embodiment of concrete structure of impeller 83
Blade wheel structure in two.When spiral case wind turbine described in embodiment two is mounted on mounting plate (not shown), usually by spiral case bottom
Be connected with spiral case cover 841 opposite side of side of plate 842 is connected with mounting plate, and mounting plate is equipped with mounting plate air inlet, spiral case
The air inlet of bottom plate 842 is opposite with mounting plate air inlet.When needing that motor or impeller are overhauled or replaced, it is only necessary to
Spiral case cover 842 is disassembled together with motor 81 and impeller 83 are integrated, spiral case bottom plate 842 need not be removed, be also not required to
Mounting plate 82 is removed, the dismounting convenience and maintainability of spiral case wind turbine are improved.
Since spiral case generally use plastic material makes, integral strength is not high, and motor 81 is mounted directly on spiral case 84
The intensity that may result in spiral case 84 is not enough to support the power of motor that spiral case is caused to deform or damage, thus, it is preferred that also
Support plate can be set, and support plate is made of metal material, and motor 81 is installed in support plate, and support plate is connected with spiral case 84 again
It connects, the power of motor is directly born by support plate, can reduce the load of spiral case.
In embodiment two, it may have the first sealing structure, the first vibration-proof structure, third as described in embodiment one subtract
Structure of shaking and/or the second vibration-proof structure or combinations thereof, first half-shell 13 of the concrete structure in 841 alternative embodiment one of spiral case cover
, no longer it is described in detail.
