Abstract
The invention discloses a ventilating fan which comprises a base 1, a bracket 2 fixed on the base 1, a wind frame 3 fixed on the bracket 2, a motor 4 fixed on the wind frame 3, and a shaft 5 of the motor 4 which is fixedly connected with fan blades (6). The front end of the ventilating fan is provided with a protective bracket 7, when people or sundries are close to the fan, people or sundries can be prevented from being blown into the fan blades which rotate at a high speed, so that injury of people is avoided; and the fan blades are protected, the protective bracket 7 can be set into different shapes as required, and different materials are selected. A fixed connecting plate 8 is arranged between the bracket 2 and the base 1; one end of the fixed connecting plate 8 is fixedly connected to the base 1, and the other end of the fixed connecting plate 8 is fixedly connected to the bracket 2; and the fixed connecting plate, the base 1 and the bracket 2 form a right-angled triangle.
Description
Technical field
The present invention relates to a kind of ventilation fan.
Background technique
Ventilation fan drives air-flow by the rotation of motor drives fan blade, makes a spacelike controlled atmosphere electricity-saving appliance of indoor and outdoor air exchange.The purpose of ventilation is exactly to remove indoor vitiated air, regulates temperature, humidity and sensory effect.Factory floor generally is the place of production and processing, in the machinery equipment operation process, inevitably produces various harmful gases or dust granules.
Summary of the invention
Make workshop condition in order to purify the unskilled labourer, remove harmful gas and dust granules, the invention provides a kind of ventilation fan.
A kind of ventilation fan comprises base 1, is fixed on support 2 on the said base 1, is fixed on wind frame 3 on the said support 2, is fixed on motor 4 on the said wind frame 3, and the axle 5 of said motor 4 is fixedly connected with flabellum (6).
The covering of the fan front end of said ventilation fan is provided with protective stent 7, and people or foreign material can prevent in its flabellum that is involved in high-speed rotation during near fan, and the one, avoided people's damage; The 2nd, protected flabellum, described protective stent 7 can be set to different shapes as required, selects material different.
Between said support 2 and the base 1 fixed connecting plate 8 is arranged, fixed connecting plate 8 one ends are fixedly connected on the base 1, and the other end is fixedly connected on the support 2, and fixed connecting plate and base 1, support 2 surround a right-angled triangle.
Said used in air exchange fan is in the manufacturing shop of factory.
Ventilation fan among the present invention, simple in structure, be convenient to make, power is big; Can effectively remove harmful gas and dust granules that workshop internal cause manufacturing operation produces, purify workshop condition, the ventilation fan base area in this invention is big; Working stability, and convenient moving.
Description of drawings
Fig. 1 is the left view of ventilation fan.
Fig. 2 is the plan view of ventilation fan.
Specific embodiment
Below in conjunction with accompanying drawing, the present invention is done further explanation.
Like Fig. 1, shown in Figure 2 for an embodiment of a kind of ventilation fan of the present invention; Comprise base 1, be fixed on support 2 on the said base 1, be fixed on wind frame 3 on the said support 2, be fixed on motor 4 on the said wind frame 3, and the axle 5 of said motor 4 is fixedly connected with flabellum (6).
The covering of the fan front end of said ventilation fan is provided with protective stent 7, and the edge of protective stent 7 is the tangent circular metal plate of a plurality of and wind frame 3, also is tangent connection between each metal disk, and said Placement is welding.The protective stent middle part has the leg-of-mutton circular plate of hollow out for being connected with a plurality of metal disks.People or foreign material can prevent in its flabellum that is involved in high-speed rotation during near fan, the one, avoided people's damage; The 2nd, protected flabellum, described protective stent 7 can be set to different shapes as required, selects material different.
Between said support 2 and the base 1 fixed connecting plate 8 is arranged; Fixed connecting plate 8 one ends are fixedly connected on the base 1; The other end is fixedly connected on the support 2; Fixed connecting plate and base 1, support 2 surround a right-angled triangle, and described right-angled triangle described in the present embodiment is an isosceles right triangle.
Said used in air exchange fan is in the manufacturing shop of factory.
Ventilation fan among the present invention, simple in structure, be convenient to make, power is big, can effectively remove harmful gas and dust granules that workshop internal cause manufacturing operation produces, has purified workshop condition.
