Abstract
The invention relates to a tower drum foundation ring of a wind driven generator, which comprises an annular body, wherein the upper end of the annular body is provided with an upper connecting part connected with the lower end of a generator tower drum, and the lower end of the annular body is provided with a lower bottom plate. The contact area between the foundation ring and the concrete is increased by arranging the radial outer reinforcing plate, the firmness is enhanced, and the tower barrel is more firmly installed.
Description
[technical field]
The present invention relates to a kind of wind-driven generator tower discharge ring, particularly for fixing the discharge ring of wind-driven generator tower.
[background technology]
MW class wind turbine group is supported on height in the air by towering tower cylinder at present, and the discharge ring under tower cylinder bears huge pressure at right angle and side direction moment of flexure.Traditional discharge ring upper end is connected with the bottom of generator tower cylinder by flange, discharge ring top radial aperture is to allow reinforcing bar pass wherein, then be embedded in concrete foundation, because the perforate on discharge ring top has reduced bonding strength, and can produce stress concentration phenomenon at tapping, accelerating structure fatigue.
[summary of the invention]
The object of the invention is to overcome the deficiencies in the prior art, the wind-driven generator tower discharge ring that a kind of bonding strength is high is provided.
In order to address the above problem, the present invention by the following technical solutions:
A kind of wind-driven generator tower discharge ring, comprise annular solid, described annular solid upper end is provided with the upper connecting portion being connected with generator tower cylinder lower end, described annular solid lower end is provided with lower shoe, it is characterized in that: on described annular solid outer wall, be circumferentially with multiple radially external reinforcing plate for cars, described radially external reinforcing plate for car is provided with the hole for wearing reinforcing bar.
A kind of wind-driven generator tower discharge ring as above, is characterized in that: on described annular solid inwall, be circumferentially with the inside stiffener in multiple footpaths.
A kind of wind-driven generator tower discharge ring as above, is characterized in that: the inside stiffener in described footpath is T-shape plate.
A kind of wind-driven generator tower discharge ring as above, is characterized in that: described upper connecting portion is flange, and described radially external reinforcing plate for car is T-shape plate.
Beneficial effect of the present invention has: the inside stiffener of multiple radially external reinforcing plate for cars and footpath is circumferentially set on annular solid, can improve the contact area between discharge ring and concrete, improve its firmness, and on external reinforcing plate for car radially, be provided with hole and pass for reinforcing bar, can not reduce the intensity of annular solid.
[accompanying drawing explanation]
Fig. 1 is the stereogram of the embodiment of the present invention 1;
Fig. 2 is the stereogram of the embodiment of the present invention 2.
[specific embodiment]
Below in conjunction with accompanying drawing and the specific embodiment, the present invention is described in further detail:
As depicted in figs. 1 and 2, a kind of wind-driven generator tower discharge ring, comprise annular solid 1, annular solid 1 upper end is provided with the upper connecting portion 2 being connected with generator tower cylinder lower end, upper connecting portion 2 is flange, the lower shoe 3 that annular solid 1 lower end is provided with, and lower shoe 3 can be in horizontal buried foundation, lower shoe 3 can guarantee the verticality of annular solid 1 like this, and generator tower cylinder is not tilted.On annular solid 1 outer wall, be circumferentially with multiple radially external reinforcing plate for cars 4; radially external reinforcing plate for car 4 is T-shape plate; radially external reinforcing plate for car 4 is provided with the hole 41 for wearing reinforcing bar, when discharge ring is embedded in to concrete, penetrates the bonding strength of guaranteeing discharge ring and concrete foundation in hole 41 by reinforcing bar.In order further to improve the bonding strength of discharge ring and concrete foundation, on annular solid 1 inwall, be circumferentially also provided with the inside stiffener 5 in multiple footpaths, the inside stiffener 5 in footpath is T-shape plate, can further improve discharge ring and concrete contact area, improves firmness.
