Abstract

The invention belongs to wind power generation equipment, and particularly relates to a triangular foundation land wind power tower foundation ring. An upper foundation ring flange (4) is welded to a foundation ring body (5), three connecting arms (3) are welded to the outer circumference of the foundation ring body (5) respectively by 120 degrees in an evenly-distributed mode, pipe columns (2) are welded to the outer ends of the connecting arms (3) respectively, bottom pipe column flanges (1) are welded to the lower ends of the pipe columns (2), a plurality of bottom pipe column flange holes (1-1) are formed in the bottom pipe column flanges (1), the bottom pipe column flanges (1) are arranged on small prefabricated foundations (8), a plurality of anchor bolts (6) are implanted to the small prefabricated foundations (8) respectively, and the anchor bolts (6) penetrate through the corresponding bottom pipe column flange holes (1-1) respectively and are fastened through fastening nuts (7). According to the triangular foundation land wind power tower foundation ring, no large foundation pit needs to be dug on the scene, the force bearing area at the bottom of a tower is increased through the separated small prefabricated foundations, larger bending moment can be borne, and the force bearing situation of the independent pipe foundations is improved.

Description

Triangle basis land breeze electricity tower foundation ring

Technical field

The invention belongs to wind-power electricity generation equipment, particularly a kind of triangle basis land breeze electricity tower foundation ring.

Background technology

Wind-power electricity generation is the renewable energy resource of tool practicality potentiality in new forms of energy, wind power tower is one of wind-power electricity generation equipment chief component, managing tower wind power tower is generally comprised of discharge ring and three sections of shell rings, during construction by the Installation and Debugging of discharge ring part qualified rear with pouring concrete to basis, other shell ring is installed on top, and discharge ring adopts the tubular type the same with pylon, the discharge ring basis of tubular type is larger, stressed bad.

Summary of the invention

The object of the invention is to overcome above-mentioned technical deficiency, provide a kind of improvement stressed, can reduce manufacturing cost, be applicable to the triangle basis land breeze electricity tower foundation ring of higher wind power tower.

The technical scheme that technical solution problem of the present invention adopts is: triangle basis land breeze electricity tower foundation ring comprises discharge ring main body, discharge ring upper flange, linking arm, what be characterized in discharge ring main body is welded to connect above discharge ring upper flange, on discharge ring main body excircle, 120 spend uniform three linking arms that weld respectively, the external end head of linking arm is welded to connect respectively tubing string, the lower end of tubing string is welded to connect flange at the bottom of tubing string, at the bottom of tubing string, flange is provided with flange hole at the bottom of a plurality of tubing strings, at the bottom of tubing string, flange is contained in respectively on prefabricated little basis, on prefabricated little basis, implant respectively a plurality of crab-bolts, crab-bolt is installed on respectively at the bottom of corresponding tubing string in flange hole and locks with clamp nut.

The invention has the beneficial effects as follows: triangle basis land breeze electricity tower foundation ring not be used in the on-the-spot large-scale foundation pit that excavates, the load area of pylon bottom is strengthened on the prefabricated little basis of discrete, be conducive to bear bigger bending moment, improved independently tubular type basic stress situation.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, with embodiment, illustrate.

Fig. 1 is triangle basis land breeze electricity tower foundation ring structure front view.

Fig. 2 is the top view of Fig. 1.

In figure, flange at the bottom of 1-tubing string; Flange hole at the bottom of 1-1-tubing string; 2-tubing string; 3-linking arm; 4-discharge ring upper flange; 5-discharge ring main body; 6-crab-bolt; 7-clamp nut; The prefabricated little basis of 8-.

The specific embodiment

Embodiment, with reference to accompanying drawing 1 ~ 2, the discharge ring main body 5 of triangle basis land breeze electricity tower foundation ring is welded to connect discharge ring upper flange 4 above, on main body 5 excircles of basis, 120 spend uniform three linking arms 3 that are welded to connect respectively, the external end head of linking arm 3 is welded to connect respectively tubing string 2, the lower end of tubing string 2 is welded to connect flange 1 at the bottom of tubing string, and at the bottom of tubing string, flange 1 is provided with flange hole 1-1 at the bottom of a plurality of tubing strings.At the bottom of tubing string, flange 1 is contained in respectively on prefabricated little basic 8, implants respectively a plurality of crab-bolts 6 on prefabricated little basic 8, and crab-bolt 6 is installed on respectively at the bottom of corresponding tubing string in flange hole 1-1 and with clamp nut 7 lockings.

The work progress of triangle basis land breeze electricity tower foundation ring is: in factory, discharge ring upper flange 4 is welded in discharge ring main body 5, again by three linking arms 3 respectively on the uniform excircle that is welded on discharge ring main body 5 of 120 degree, at the external end head welding tubing string 2 of each linking arm 3, at the bottom of the lower end welding tubing string of tubing string 2, after flange 1, transporting to job site.By the assembly of flange 1 at the bottom of discharge ring upper flange 4, discharge ring main body 5, linking arm 3, tubing string 2, tubing string with crane lifting on prefabricated little basic 8, crab-bolt 6 is installed on respectively at the bottom of corresponding tubing string in flange hole 1-1, then with clamp nut 7, is locked.

Claims

1. triangle basis land breeze electricity tower foundation ring, comprise discharge ring main body (5), discharge ring upper flange (4), linking arm (3), what it is characterized in that discharge ring main body (5) is welded to connect above discharge ring upper flange (4), uniform three linking arms (3) that weld respectively of 120 degree on discharge ring main body (5) excircle, the external end head of linking arm (3) is welded to connect respectively tubing string (2), the lower end of tubing string (2) is welded to connect flange (1) at the bottom of tubing string, flange at the bottom of tubing string (1) is provided with flange hole (1-1) at the bottom of a plurality of tubing strings, flange at the bottom of tubing string (1) is contained in respectively on prefabricated little basis (8), on prefabricated little basis (8), implant respectively a plurality of crab-bolts (6), crab-bolt (6) is installed on respectively at the bottom of corresponding tubing string in flange hole (1-1) and with clamp nut (7) locking.
