Detailed Description
In order to make the technical problem, technical scheme and beneficial effect that the utility model will solve more clearly understand, combine embodiment and attached drawing, it is right to go on further detailed description the utility model discloses. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. The technical solution of the present invention is described in detail below with reference to the embodiments and the drawings, but the scope of protection is not limited thereto.
As shown in FIG. 1, the fan stop alarm device of the present invention has a vertical arrangement of the fan, and the wind of the fan goes from the bottom to the bottom
The upper blowing device is characterized in that the alarming device is arranged on the outer side of a fan close to an air outlet or on the outer side of reactive compensation equipment close to an air inlet, the alarming device is a hollow shell and comprises a shell 1, a rotating shaft 2, magnetic blades 3 and a voice alarm 7, a flange face extends out of the lower portion of the shell, a mounting hole 9 is formed in the flange face and used for fixedly mounting the alarming device through bolt connection, the rotating shaft 2 is horizontally fixed on the shell 1, the magnetic blades 3 are sleeved on the rotating shaft 2 and can rotate around the rotating shaft 2, a hairspring 4 is sleeved on the rotating shaft 2, two ends of the hairspring 4 are placed on the surfaces of the magnetic blades 3 and used for returning the magnetic blades 3, a first positioning plate 5 is arranged on the upper side of the magnetic blades 3, the first positioning plate 5 is located at a position where the magnetic blades 3 rotate around the rotating shaft 2 by 90 degrees and used for keeping the magnetic blades 3 at the original position, block magnetic vane 3 and excessively rotate, magnetic vane 3's downside sets up second locating plate 6, magnetic vane 3's surface is hugged closely to second locating plate 6, set up magnetic switch 8 on the audible alarm 7, magnetic switch 8 places on second locating plate 6, first locating plate 5 is 90 degrees with second locating plate 6 and places, audible alarm 7 sets up on the casing installation face, also can set up in other places that can make the staff hear the warning sound, alarm device also can install other places, as long as install can by the fan and the wind-force that receives can make magnetic vane 3 rotate the position of first locating plate 5 can.
The magnetic blade 3 is formed by arranging a magnetic material 31 on the blade 3; the second positioning plate 6 is arranged to maintain the magnetic blades 3 at the initial position when the fan stops rotating, and prevent the magnetic blades 3 from continuing to rotate after returning; the installation position of the warning device can also be installed on the outer side of the equipment close to the air inlet, and the installation position is required to be the installation position as long as enough wind can make the magnetic blades 3 far away from the initial position when the fan runs and return to the initial position when the fan stops running.
The working principle is that as shown in fig. 3, when the fan normally operates, the magnetic blade 3 rotates by a certain angle under the action of wind power until the magnetic blade is blocked and positioned by the first positioning plate 5, the hairspring spring 4 is compressed, the wind power maintains the magnetic blade 3 at the position blocked by the first positioning plate 5, at the moment, the magnetic switch 8 does not act, the power supply of the voice alarm 7 is not switched on, and the voice alarm is not sent out; as shown in fig. 2, when the fan stops rotating, the magnetic blade 3 rotates and returns under the action of the balance spring 4 until being blocked and positioned by the positioning plate 1, at the moment, the magnetic blade 3 triggers the magnetic switch 8 on the second positioning plate 6, the power supply of the voice alarm 7 is switched on, and the voice alarm is given out.
