In the surface of four supporting rods；It is hinged with electric cylinder on the pedestal, actuating arm is fixed on the piston rod of electric cylinder, drives
Arm is connect with the first support arm on front side of rectangular slab.
The bottom of the electric cylinder is fixed with journal stirrup, and journal stirrup forms the through-hole of front-rear direction extension, and through-hole sleeve is being cut with scissors
On the cross bar of joint chair, hinged seat is fixed on the upper bottom surface of pedestal, and the electric cylinder is located at the front side of rectangular slab.
The actuating arm is in " U " font, and one end of actuating arm is fixed on the piston rod end of electric cylinder, actuating arm it is another
Hold sleeve in the interstitial hole of the first support arm.
The length of first support arm is equal to the length of the second support arm.
Step surface is formed in the middle part of the supporting rod, the medial surface of the first support arm is pressed against the platform of the centre of supporting rod
On terrace.
The protrusion effect of the utility model is：
Compared with prior art, it can adjust the height of blast cap, and to improve fan efficiency to greatest extent, while wind turbine stops
Blast cap can be transferred to extreme lower position when machine, prevent sleet from entering.
Description of the drawings：
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is other side structure schematic diagrames for blurring blast cap of the utility model.
Specific implementation mode：
Embodiment is shown in as shown in Figure 1 to Figure 2, a kind of liftable energy-saving roof fan of blast cap, including pedestal 11, bottom
It is fixed with air duct 12 on seat 11, motor and flabellum are equipped in air duct 12, the top of air duct 12 is equipped with blast cap 13, and the blast cap 13 is logical
It crosses elevating mechanism 2 to connect with air duct 12, the elevating mechanism 2 includes the rectangular slab 21 being fixed on the outer wall of air duct 12, rectangle
There are one the supporting rods 22 of outwardly convex for each fixation on four sides of plate 21, and each supporting rod 22 is hinged, and there are one the first supports
Arm 23, the upper end of the first support arm 23 and the lower end of the second support arm 24 are hinged, and the upper end of the second support arm 24 is hinged on " L " type
The other end of one end of bar 25, " L " type bar 25 is fixed on the inner wall of blast cap 13, and four " L " type bars 25 are located at four branch
The surface of strut 22；It is hinged with electric cylinder 26 on the pedestal 11, actuating arm 27 is fixed on the piston rod of electric cylinder 26, drives
Swing arm 27 is connect with the first support arm 23 positioned at 21 front side of rectangular slab.
Further, the bottom of the electric cylinder 26 is fixed with journal stirrup 28, and journal stirrup 28 forms front-rear direction extension
Through-hole, on the cross bar of hinged seat 29, hinged seat 29 is fixed on the upper bottom surface of pedestal 11 through-hole sleeve, the electric cylinder 26
Positioned at the front side of rectangular slab 21.
Further, the actuating arm 27 is in " U " font, and one end of actuating arm 27 is fixed on the piston of electric cylinder 26
Boom end, the other end sleeve of actuating arm 27 is in the interstitial hole 231 of the first support arm 23.
