Description

If cooling mechanism is detachably connected the transformer that umbrella can mow
This case is application number 2016110971186, and on December 02 2016 applying date, title " it is detachable to set cooling mechanism The divisional application of the transformer that Connectable umbrella can mow ".
Technical field
The present invention relates to transformers more particularly to a kind of cooling mechanism that sets to be detachably connected the transformer that umbrella can mow.
Background technology
Transformer is the device for changing alternating voltage using the principle of electromagnetic induction, and main member is winding(It is i.e. primary Coil, secondary coil)And iron core(Magnetic core).Major function has:Voltage transformation, current transformation, impedance transformation, isolation, voltage stabilizing(Magnetic Saturation transformer)Deng.It can be divided into, according to use,:Power transformer and special transformer(Electric furnace change, rectification change, industrial frequency experiment become Depressor, pressure regulator, mining change, audio-frequency transformer, intermediate-frequency transformer, high frequency transformer, impact transformer, instrument transformer, electricity Sub- transformer, reactor, mutual inductor etc.).Existing transformer has the following disadvantages:It can not be hidden using at outdoor Sun, aging speed are fast;It needs artificial removal careless when growing grass by transformer, manually goes weeding safety by transformer poor;Only pass through Radiator radiates, and heat dissipation effect is poor.
Invention content
The present invention provides it is convenient when a kind of good heat dissipation effect, installing and dismounting umbrella and can mow to set cooling mechanism removable Unload the transformer that Connectable umbrella can mow, solve existing transformer lack sun-shading mechanism, need manually go installation point weeding and The problem of the heat dissipation effect for radiating existing difference is only carried out by radiator.
The above technical problem is solved by following technical proposal:One kind setting cooling mechanism and is detachably connected umbrella and can mow Transformer, including transformer body, the transformer body includes the shell equipped with transformer oil, is provided in the shell The iron core and winding being submerged in transformer oil, which is characterized in that further include external rotor electric machine, umbrella and cooling mechanism, it is described outer Rotor electric machine includes inner stator and outer rotor, and the inner stator is vertically arranged and constitutes the support leg of the transformer body, institute It states outer rotor and is equipped with the blade extended along external rotor radial, the pack includes umbrella stem and umbrella cover, and the umbrella stem is matched by thread head Closing nut and being connected to the upper end of the shell makes umbrella cover when strutting umbrella cover block on the housing, the cooling mechanism packet Include circulating pump that radiator casing, the driving transformer oil being connected to the shell recycled between radiator casing and shell, Bucket below heat-dissipating casing, the fan blade of the updraft above radiator casing, in radiator casing Interior stirring blade, lower stirring blade and fan electromotor in the bucket below radiator casing, the fan electromotor is for driving Move the fan blade, interior stirring blade and the rotation of lower stirring blade.Umbrella is set on the shell, can be incited somebody to action when use is in outdoor Umbrella support is opened carries out sun-shading rain-proof to transformer body, to overcoming when existing transformer is mounted on outdoor by direct sunlight The problem of caused aging block.Meter external rotor electric machine is divided into shell and is supported by the stator of the motor of outer rotor, is tied Structure compactedness is good;External rotor electric machine designs blade, can be by outer rotor motor driven blade rotation by the grass by transformer It cuts off, without artificial close when weeding, safety when weeding is good.In use, transformer oil passes through under the action of circulating pump Heat is lost when radiator casing.The radiation processes of radiator are other than the existing natural heat dissipation by radiator casing, fan Blade certain driving air-flow flow through from bottom to top radiator casing outer surface play the role of accelerate heat dissipation to improve heat dissipation effect, take to The mode of upper pumping radiates so that the power of fan blade certain driving air-flow flowing is in the same direction with the power that hot gas rises, to more It flows away added with the hot-air conducive to radiator casing surface;Fan blade can also play when rotating carries out sunshade to radiator casing Effect so that the Wen Sheng little of radiator casing caused by the sun, namely radiator casing is preferably radiated;Fan leaf The timely temperature rise of piece, but due to radiating for upper air-draft-type, therefore air-flow will not shadow by temperature rise in fan blade in time It rings radiator casing, the temperature for blowing to the air-flow of radiator casing can be caused higher if downward blowing, heat dissipation effect is caused to be deteriorated. Stirring blade in setting, can improve transformer oil with the heat exchanger effectiveness between radiator casing so that the heat of transformer oil Quickly fully radiator casing can be passed to me and lose.Bucket is set and bucket is located at the lower section of radiator casing, water Wen Sheng little caused by the heat that water in bucket is shed by radiator casing, while radiator casing can play and carry out sunshade to bucket Effect, lower stirring blade is stirred the water in bucket to accelerate the water heat absorption in bucket, so that on bucket The air themperature of side is relatively low, which can get a promotion to the heat dissipation effect of radiator casing when rising.
Preferably, the lower end of the inner stator is equipped with support seat board.By supporting seat board to be supported on ground when use To realize the support to the present invention.Stationarity when support can be improved.
Preferably, the support seat board is equipped with the connection unthreaded hole vertically extended.By by lower margin spiral shell when use Bolt is connected to after connection unthreaded hole realizes that the installation of the present invention is fixed on ground, convenience when fixed is good.
It is vertically extended along the circumferential uniform of the outer rotor preferably, the support seat board is equipped at least three The tapped through hole of distribution, the tapped through hole internal thread are connected with Level-adjusting bolt.By rotating levelness tune when use Whole bolt come adjust the present invention installation when levelness.It is convenient when adjustment is horizontal.
Preferably, the outer surface of the radiator casing is equipped with radiating fin.Heat dissipation effect can be improved.
Preferably, the fan electromotor includes motor shaft and the electric machine casing that is fixed on radiator casing, the motor Axis runs through radiator casing along the vertical direction, and the fan blade, interior stirring blade and lower stirring blade are all connected to the motor On axis.Structural compactness is good.
Preferably, the nut includes collar nut ontology and the internal thread that is arranged on nut body inner peripheral surface, institute The inner peripheral surface for stating nut body is equipped with and extends to the straight slot of the other end along one end of nut, and the straight slot is by the internal thread edge The circumferential of nut body disconnects, and the nut body is connected to the another of straight slot equipped with the side side wall rear thread across the straight slot Straight slot groove width adjusting screw on the side wall of side.Bolt attaching nut is fixed, easy for assemble or unload.It is locked after nut check logical Slot groove width adjusting screw and make straight slot reduced width, the result of diminution be to make the more tightly holding of internal thread on bolt, So that not allowing to be also easy to produce loosening and cause to send out fan electromotor connection loosening between nuts and bolt.
Preferably, the straight slot has two.Locking effect want and spend screw thread execution it is small.
Preferably, two straight slots are uniformly distributed along the circumferential direction of nut body.It can effectively prevent nut generation office Portion's fragility phenomenon.
