Description

Anti-icing agent spraying device for wind driven generator blade and using method
Technical Field
The invention relates to an anti-icing agent spraying device for a wind driven generator blade and a using method of the anti-icing agent spraying device, and belongs to the technical field of spraying devices.
Background
Wind power generation is rapidly developed in recent years, but in a humid and cold climate area of China, blades of a wind power generator often face the problem that the surfaces of the blades are easy to freeze, so that the pneumatic performance of the blades of the wind power generator is damaged, the power generation efficiency is reduced, the service life is prolonged, and related technologies are continuously developed. The existing deicing modes of the wind generating set are mainly divided into active deicing and passive deicing.
The active deicing technology is mainly divided into gas-heat, electric-heat and gas-electricity combined technology, and the deicing and anti-icing effects of the blades can be realized in a mode of transferring heat by a heating medium, namely, a method for preventing supercooled water drops from freezing is adopted, and the method is usually resistance wire heating deicing and surface indirect heating deicing. The deicing technology has the defects that a heating system is complicated, the heating degree is not enough to cover the whole blade, and the deicing effect is poor for large-size blades; meanwhile, certain energy and professional supporting facilities are needed, so that the contradiction between power generation output and power consumption is caused. The active deicing technology also comprises a mechanical deicing method, namely, the blade is vibrated by means of knocking, vibration, ultrasound and the like, so that the ice coating falls off. The disadvantages of mechanical de-icing are: is easy to damage the wind generating set and is not suitable for large-scale wind generating sets.
The passive deicing technology is mainly a technology for spraying an anti-icing coating, the coating anti-icing is a simple and green anti-icing technology, the service life of the coating is long at present, and the blade deicing is realized by weakening the adhesive force between the ice coating and the coating surface. However, the spraying effect of the existing spraying device is poor, and only fixed-point spraying can be realized, namely spraying work is carried out on the blades through spraying of two sides of a bidirectional nozzle of a fixed workbench, so that dynamic spraying cannot be realized, namely the blades of a wind driven generator are required to stop working during spraying, the wind power generation process is influenced, and the defects of complex operation and maintenance exist; in addition, when the existing spraying device is used for spraying blades, the wind direction under natural conditions can seriously affect the spraying effect, and relevant documents report that: when the wind direction included angle and the spraying direction are more than 30 degrees, the wind direction included angle and the spraying direction are difficult to spray on the blades, so that the spraying effect is greatly reduced, but the wind driven generator is arranged in a place with large wind, and the change of the wind direction is an inevitable natural phenomenon, so that the problem of solving the influence of the wind direction on the spraying effect is also a problem to be solved urgently in the field.
In addition, the blade is sprayed in an automatic spraying mode, the technical problem of a climbing mechanism can be also involved, and the existing tower climbing equipment comprises the following components: in CN111716371A, crawling on a tower drum is realized by combining magnetic adsorption with a crawler belt, which requires that the tower drum is made of iron material capable of being adsorbed by magnetic force, but the current wind driven generator tower drum is often made of other materials and cannot realize magnetic adsorption, so that the current climbing structure is poor in universality; in the climbing device in CN203064069U, the climbing device cannot be kept horizontal at a higher position of the tower with a thinner diameter, and if the climbing device is used in a spraying process, a nozzle head of a spraying mechanism cannot be directly opposite to a blade, so that spraying deviation is caused; in CN210286647U, a plurality of steel cable guides are used for clamping and climbing a tower drum, the structure is complex, the maintenance is inconvenient, the overall weight of the equipment is increased, and the use is inconvenient; in CN109850028A, a winch, a prop-off machine and other structures are used for assisting in realizing climbing of a tower drum, the structure is complex, and if the device is used in a wind power plant in a large scale, the equipment cost is high; in addition, the conventional tower climbing structure generally only can climb or descend, and cannot realize angle adjustment of a nozzle head when used in a spraying process.

3) climbing and ascending: under the action of the tension adjusting motor 13, the tension belt 14 is gradually tightened; under the action of the hydraulic cylinder 4, the positive pressure crawling arm 3 applies positive pressure to enable the whole anti-icing agent spraying device to clamp a tower barrel, the crawling crawler 11 runs to drive the whole anti-icing agent spraying device to crawl upwards, the crawling height can be controlled through cloud data, and the crawling height can also be determined through the sensing data of the position probe sensor;

The control system is also associated with a meteorological prediction control device of a local wind power plant, and when the conditions of air temperature, air humidity, wind speed and the like of the wind power plant in a future period of time are predicted to reach the threshold value for icing the blades of the wind turbine through a big data algorithm, the control system controls the operation of the whole anti-icing agent spraying device and carries out anti-icing agent spraying operation on the blades of the wind driven generator. Meanwhile, the whole control system selects the spraying amount of the anti-icing agent according to the predicted duration time of the extreme weather and whether to perform intermittent spraying or not (the intermittent spraying is to perform spraying once every other period of time within the duration time of the extreme weather so as to achieve the effect of continuously controlling anti-icing).
The specific flow of the creeping process and the spraying process is shown in fig. 8-9.
In the spraying process, the nozzle head faces to the leeward side of the blade, and the anti-icing agent is sprayed and then dispersed around the blade, so that the anti-icing agent is attached to the windward side and the leeward side of the blade, and in the whole spraying process, the rotation of the blade of the wind driven generator does not need to be stopped, and the normal wind power generation process cannot be influenced, wherein the blade structure of the wind driven generator is shown in fig. 10.
In addition, in order to make the spraying process of the anti-icing agent more accurate, data analysis is also performed on relevant conditions of the spraying process, and the specific contents are as follows:
when the model analysis and data processing are carried out within the reasonable range of the invention, the spraying times are set as a variable a, the spraying times b, the spraying pitch is set as a variable c, the incoming flow wind speed is set as a variable d, and the backward attachment rate is set as a dependent variable y. The data from the simulation experiments were analyzed using SPSS data analysis software.
The "average adhesion rate" is a random variable at a fixed distance level, and the "incoming flow wind speed", "jet pitch", and "number of spraying times" are regarded as independent variables, and the influence of the three independent variables of the "incoming flow wind speed", "jet pitch", and "number of spraying times" on the "average adhesion rate" can be studied by using a multivariate linear regression analysis method. The "average adhesion rate" refers to: the average value of the adhesion rates of the sprayed anti-icing agent on the windward area, the leeward area and the front edge area of the blade used in the experiment is obtained.
Condition satisfied by multiple linear regression analysis
According to FIG. 11, the histogram is fit to the normal curve; each point in fig. 12 is substantially on the diagonal of the square, and it may be concluded that the residuals approximate a normal distribution of the service. According to fig. 13 (plot of the normalized residual as Y-axis and the normalized predicted value as X-axis), the residuals are substantially randomly distributed and within ± 1 standard deviation, so the equation satisfies the assumption of residual homogeneity. In summary, the residual error satisfies the precondition assumption conditions of normality, equal variance and mutual independence, and regression analysis can be performed.
(II) analysis of multiple regression results
The multiple regression analysis used stepwise regression, and according to table 1, there were no rejected variables in the stepwise regression analysis. The final regression equation is given by table 2 as: the average adhesion rate is 26.370+5.344 × the number of spraying times-5.348 × the incoming flow wind speed-43.274 × the spraying pitch. The normalized regression equation is: the average adhesion rate is 0.749 times the number of spraying times-0.433 times the incoming flow wind speed-0.350 times the spraying pitch. The number of spraying times has the greatest effect on the average adhesion rate as judged by the normalized regression coefficient (normalized regression coefficient of 0.749), followed by the incoming flow velocity (normalized regression coefficient of-0.433). And according to table 2, the allowances are all greater than 0.5, the VIFs are all less than 10, indicating that no collinearity exists between the respective variables of the equations. According to table 3, the decision coefficient of the last model is 0.870, and the adjusted decision coefficient is 0.861, so that the fitting effect of the equation is very good. According to table 4, the last model has F91.784, corresponding to a sig value of 0.000, and therefore the regression equation has inferential significance, while according to table 2, the t value of each argument corresponds to a probability value of less than 0.05, and therefore each argument has inferential significance.
