Description
Technical field
This utility model technology belongs to wind field design field, relates to a kind of wind energy turbine set wind-driven generator tower strengthening of foundation device。
Background technology
In recent years, along with large-scale development wind-power electricity generation, China has become as whole world installed capacity of wind-driven power the first big country。Blower foundation as the important component part of Construction of Wind Power, the not only safe and reliable operation of relation wind field, have an effect on the investment repayment of wind field。Blower foundation is the reinforced concrete structure for fixing wind power generating set, and it not only to bear the weight of wind-driven generator and blower fan tower barrel, also to resist the wind load that topples of Wind turbines, it is ensured that Wind turbines safe operation under various load actions。Because having the advantage that construction technology is simple and cost is low, cast-in-situ steel reinforced concrete circular enlargement basis is to adopt base form the most widely at present, is conducted oneself with dignity by basis and upper earthing heavily offsets the wind load that topples suffered by unit。
Cast-in-situ steel reinforced concrete circular enlargement basis is to be inserted in blower foundation (armored concrete material) by blower fan tower barrel (steel matter), because of bi-material different in kind used by blower fan tower barrel and blower foundation, its adhesion strength is limited, in conjunction with defective tightness, under meeting greater level wind action, gap can top down be developed gradually therebetween, development along with gap, stack shell Oscillation Amplitude strengthens, and exceedes fan vibration alarm limit, makes blower fan unit be not normally functioning。
It addition, there is the problem of development for tower and gap, contact surface place, basis, existing conventional Scheme of Strengthening is generally deep drill slip casting blind, and foundation platform top is increased and does for supplement waterproof layer on cushion cap surface。But it can not thoroughly solve problem, and complicated construction technique, long in time limit, cost is high。
Utility model content
This utility model can solve the problem that cast-in-situ steel reinforced concrete circle is expanded blower fan tower barrel in basis and disengaged with basis, the defect that integrity is not strong, it is provided that a kind of action effect is notable, easy construction, wind energy turbine set wind-driven generator tower strengthening of foundation device with low cost。
This utility model solves the technical scheme that its technical problem adopts:
A kind of wind energy turbine set wind-driven generator tower strengthening of foundation device, including steel hoop and dowel, described steel hoop is positioned at outside the tower of wind-driven generator, in the reinforced concrete foundation of steel hoop embedment wind-driven generator, dowel is welded in outside steel hoop, is separated by ultra-high molecular weight polyethylene board between described steel hoop and tower。
Further, described steel hoop adopts Q345 material steel plate to process；Dowel adopts φ 20mm grade III steel muscle spacing 150mm horizontal radiation。Dowel is welded on steel hoop by plug welding mode of boring a hole。
Further, described steel hoop is made up of the split anchor ear of two semicirculars in shape, is connected by high-strength bolt between two split anchor ears。
Further, connected by four high-strength bolts between described two split anchor ears。
Ultra-high molecular weight polyethylene board refers to molecular weight polyethylene board more than 1,500,000, for prior art。
In this utility model, make blower fan tower barrel and basis contact as a whole by dowel effect。Blower fan tower barrel is as load-supporting part most important in fan operation process, scene is not allowed to carry out the welding of dowel outside tower, in order to avoid thermal stress is concentrated, tower entirety stress and stability are had undesirable effect, if welding radiation reinforcing bar, brings difficulty can to tower (diameter 4.2 meters) transportation in tower manufacture process。And outside tower, increasing steel hoop, outside steel hoop, weld horizontal radiation dowel can be good at solving this problem, relies on the dowel being anchored in blower foundation to resist horizontal pull, makes blower fan tower barrel cannot come off with basic contact surface, produce gap。Separate with ultra-high molecular weight polyethylene board between steel hoop and tower, in order to avoid the mutual abrasion between steel plate, thus can be reasonably resistant to horizontal wind excitation, stop the crack between foundation ring and cushion cap to be developed to deep, blower fan tower barrel will not be had undesirable effect again。
This utility model simple in construction, it is possible to thoroughly the problem of development occurs for radical cure tower and gap, contact surface place, basis, and easy construction, cost are low, efficiency is high, cause damage light。
