Abstract
The utility model relates to a differential settlement observation device for a wind turbine foundation. The differential settlement observation device comprises a luminous source and a scale plate, wherein the scale plate is used for identifying slopes; the luminous source is a concentrated light source, installed on a fan tower drum through a light source support and located above a core drum; and the scale plate is fixed under the luminous source and on a foundation surface inside the core drum, and concentric rings in different colors are identified on the upper surface of the scale plate. According to the differential settlement observation device, through calculation and conversion, the slope of the foundation is displayed through scales in the scale plate, that is, a final result can be observed directly through readings, so that the device is easy to operate, errors caused by observation and calculation are reduced, and timely observation is facilitated.
Description
Technical field
The utility model relates to a kind of observation device, relates in particular to the observation device whether a kind of special observation wind driven generator base inclination, sedimentation occur.
Background technology
Wind energy conversion system is towering structure, towering structure requires very high to basic sedimentation and non-uniform settling, especially wind energy conversion system is in operation and mainly is subject to horizontal wind action, superstructure produces Moment to basis, more easily cause the non-uniform settling of gravity type foundation, if the foundation uneven settlement amount is excessive, can affect even tower of top unit normal operation, so will regularly to basis, carry out non-uniform settling observation in the Wind turbine operational process.Conventional way is: on the Core Walls Structure position of basseting on every wind energy conversion system basis, symmetry is buried four settlement observation points underground, be generally steel bar end or rivet, be in operation and regularly by surveying instrument, observation station carried out elevation observation, arranges observation data, with raw data, contrasted, calculates, draw basic slope, judge whether non-uniform settling exceeds standard.In observation and a series of activities such as calculating, set up instrument, measurement, record, comparing calculation etc., workload is large, program is numerous and diverse, not easy to operate.In artificial measuring process, unavoidable generation instrument error, environmental error, method error, personal error etc., if the accumulation of various error component likely misleads final result, brought certain hidden danger to the safety of wind energy conversion system basis and top unit.
The non-uniform settling observation device of the utility model in the wind driven generator base industry yet there are no application and report.
Summary of the invention
The purpose of this utility model is to propose a kind of simple in structure, can observe intuitively the wind energy conversion system foundation uneven settlement observation device of the slope of foundation uneven settlement.
The purpose of this utility model is achieved in that wind energy conversion system foundation uneven settlement observation device, and it comprises a light emitting source, and one in order to identify the bidding quotation of degree of tilt, described light emitting source is bundling light source, and light emitting source is installed on blower fan tower barrel by light source bracket, is positioned at the Core Walls Structure top.On fundamental plane in Core Walls Structure, be fixed with bidding quotation under light emitting source, bidding quotation upper surface sign has the concentric ring of different colours.
The utility model is by after calculating, changing, and the slope of the scale display base in bidding quotation, can directly observe net result by reading, easy and simple to handle, has reduced due to observation and has calculated the error produced, and also is convenient to timely observation.
The accompanying drawing explanation: concrete structure of the present utility model is provided by following drawings and Examples:
Fig. 1 is wind energy conversion system foundation uneven settlement observation device structural representation.
Legend: 1. blower fan tower barrel, 2. light source bracket, 3. bidding quotation, 4. Core Walls Structure, 5. fundamental plane, 6. light emitting source.
Embodiment:
The utility model is not subject to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.
Embodiment: as shown in Figure 1, it comprises a light emitting source 6 wind energy conversion system foundation uneven settlement observation device, and a bidding quotation 3 in order to identify degree of tilt, described light emitting source 6 is bundling light source, as laser, light emitting source 6 is installed on blower fan tower barrel 1 by light source bracket 2, is positioned at Core Walls Structure 4 tops.On fundamental plane 5 in Core Walls Structure 4, be fixed with bidding quotation 3 under light emitting source 6, bidding quotation 3 upper surface signs have the concentric ring of different colours.
The vertical range at described light emitting source 6 centers, lower end to bidding quotation 3 centers, upper surface is 7-10 meters, and on described bidding quotation 3, the concentric ring width is 0.7-1cm, and the center circle radius is 1.4-2cm.
Light source bracket 2 level connection joints of described light emitting source 6, on blower fan tower barrel 1, are lifted with light emitting source 6 at light source bracket 2 front ends, between described light emitting source 6 and light source bracket 2, for flexibly connecting, for example by climbing rope, hang and connect.
The concentric ring of described bidding quotation 3 annulus from the inside to the outside represents respectively normally, tilt boundary, be in extreme danger.
When non-uniform settling occurs in the wind energy conversion system basis, blower fan tower barrel 1 is with the wind energy conversion system basic slope, bidding quotation 3 tilts with fundamental plane 5 simultaneously, light emitting source 6 is under Action of Gravity Field, and the light of its emission is perpendicular with ground level all the time, and the angle of inclination of comparing light emitting source 6 due to the angle of inclination of bidding quotation 3 is much smaller, substantially can ignore, thereby make the hot spot occurrence positions fallen within bidding quotation 3 change, according to hot spot different concentric ring of living in, can observe intuitively inclined degree.
Above technical characterictic has formed most preferred embodiment of the present utility model, can increase and decrease inessential technical characterictic of the present utility model according to actual conditions, to meet actual needs.
