Abstract
The utility model discloses a kind of frost prevention motor shroud more particularly to a kind of rotatable frost prevention motor shrouds of bilayer.Two layers of new grid of production and former grid same outer diameter size increases grate opening away from being separated by between two layers of grid with washer, be fixed on original motor hole location after its center point punching bolt-through.The utility model is installed using the original installation hole location of motor shroud, reasonable in design, in the case where effectively avoiding temperature low humidity big, frosting in motor shroud, the problem of blocking air inlet, influence air-cooled efficiency after formation frost layer.Simple labyrinth structure is formed between two layers of grid simultaneously, while frost prevention, ventilation, avoids the entrance of foreign matter, under various circumstances, angle can rotate adjustment between two layers of grid, applied widely.
Description
Technical field
The utility model relates to a kind of frost prevention motor shroud more particularly to a kind of rotatable frost prevention motor shrouds of bilayer.
Background technique
Motor mostly uses air-cooled design at present, is equipped with shield in air inlet to stop foreign matter to enter, and plays protection electricity
The purpose of machine inner rotator.Motor air inlet shield is to guarantee air intake, mostly grating type.In the pumping operation of electric motor fan
Under, temperature is obviously lower than ambient temperature at grid, once in the case where autumn and winter environment temperature also reduces, shield lattice
Temperature can drop to frost point hereinafter, if air themperature is larger (for example hazing) at grid, the easily frosting on shield grid.With when
Between extend, frostwork gradually overlaps, and forms one layer of white shell, influences motor shroud intake, lead to motor cacophonia, temperature liter
Height, vibration aggravation, influences service life of equipment, there are security risks.
Furthermore in disclosed motor shield patent, Changzhou Rui Fengte Science and Technology Ltd. discloses a kind of electric motor protecting
Cover, including bottom plate, location hole, lower radiator fan, movable pulley, threaded hole, upper radiator fan, ventilation hole, fixation hole, locating piece,
Frame, solar panel, tank wall, battery, oil storage tank and oil pipe, frame upper side are provided with solar panel, the invention
Installation is succinct conveniently, and has certain dust-proof, rain and snow function, while also having good heat sinking function, and autonomous confession
Electric facility.However, this design structure is complicated, auxiliary system is more, is unfavorable for using and safeguarding for later period.Tianjin Beijing Railway Bureau iron
Road rolling stock accessory factory discloses a kind of motor protecting cover, including the first guard shield plate and the second guard shield plate, two guard shield plates are encircled
In the position for corresponding to fan outside motor casing；Two guard shield plates are arranged at one end through hinge connection in the other end of two guard shield plates
There is connection component.This design efficiently solves ventilating problem, prevents blade from getting, but is not adjustable the size of ventilation opening,
Protection is entered not enough for foreign matter, there are security risks.
Summary of the invention
To solve the above-mentioned problems, the utility model provides a kind of novel frost prevention motor shroud.It is intended that providing
A kind of rotatable frost prevention motor shroud of bilayer, makes it under the premise of guaranteeing ventilation rate, has anti-frosting function, effectively avoids tying
Intake caused by frost is reduced, and prevents motor overheating, meanwhile, to adapt to Various Seasonal and environmental requirement, using rotatable adjustable
Section structure design, grid is adjustable, and structure is simple, very practical.
To achieve the above object, frost prevention motor shroud provided by the utility model is achieved in that as shown in the picture, is torn open
After the original grid of motor shroud, new production grid is upper grid (1) and Under The Grille (2) respectively.Under The Grille is fixed on motor original
After grid hole location, punching bolt (4) passes through upper grid (1) center hole, is installed in Under The Grille (2) using screwed connection
On heart hole, by the support force of washer (3) and the pulling force of punching bolt (4), so that upper grid (1) and Under The Grille (2) is tensed,
Realize the fixation of the two.Washer (3) and upper grid (1) and Under The Grille (2) are in close contact, and it is whole that side forms sealing.
If hereafter also needing to adjust, punching bolt (4) is unscrewed, it can grid (1) is freely rotated in realization, arrives
Punching bolt (4) are tightened after suitable position again, can realize fixation again.
Since the utility model is using the double-deck rotatable structure, so as to obtain it is following the utility model has the advantages that
First, in the case where effectively avoiding temperature low humidity big, frosting in motor shroud blocks air inlet after forming frost layer
Mouthful, influence air-cooled efficiency.
Second, upper grid (1) and Under The Grille (2) form simple labyrinth structure, while frost prevention, ventilation, avoid foreign matter
Entrance.Meanwhile Dual-layer shield grid is controlled by punching bolt (4), eccentric angle is adjustable, adapts to varying environment
Under motor requirement.
Third, it is reasonable in design, it is easy to process, while can use original shield hole location installation, do not need increase volume
Outer cost.
4th, it adopts the structure, reduces the operation of frequent inspection defrosting, reduce personnel labor intensity.
Detailed description of the invention
The utility model is described in further detail below in conjunction with attached drawing.
Attached drawing 1 is the utility model main view；
Attached drawing 2 is the utility model side view；
Wherein, (1) is upper grid；
It (2) is Under The Grille；
It (3) is washer；
It (4) is punching bolt
Specific embodiment
As shown in attached drawing 1 and attached drawing 2, preferred embodiments of the present invention are: making upper grid (1) He Xiage respectively
Grid (2), the two grid spacing are original twice of size of grid spacing, and frostwork when frosting is avoided to overlap to form entirety.Under The Grille is solid
After being scheduled on motor original grid hole location, punching bolt (4) passes through upper grid (1) center hole, is installed to lower lattice by screwed connection
On the center hole of grid (2), upper grid (1) is tensed to Under The Grille (2).Washer (3) is located at upper grid (1) and Under The Grille (2)
Centre, and be in close contact with the two, it is whole that side forms sealing.Punching bolt (4) designs for hand wheel structure, convenient to adjust at any time
Eccentric angle, to adapt to the requirement of different use environments.
The working principle of the utility model and the course of work are as follows: after installing novel frost prevention shield, Under The Grille (2) is solid
Determine structure, unscrew punching bolt (4), the angle of grid (1) in adjustment is tightened punching bolt (4) after angle adjustment is suitable, led to
Both the support force of washer (3) and the pulling force of punching bolt (4) are crossed, so that upper grid (1) and Under The Grille (2) is tensed, realize
It is fixed.Washer (3) is the structure for itself being welded on Under The Grille (2), without being adjusted.Normally-open motor use.
