BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 The utility model is a schematic structural diagram of an automatic putty scraping device in a preferred embodiment. DETAILED DESCRIPTION

[0017] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0018] like Figure 1 As shown, the automatic putty scraping device in this embodiment includes a mobile base 1, on which a pump barrel 8 and a central control system 9 are provided, and a rocker mechanism 2 is also provided on the mobile base 1, and the rocker mechanism 2 includes three arms 21, 22, and 23, and the adjacent arms are connected by first pivoting mechanisms 24 and 25, and the first pivoting mechanisms 24 and 25 are electrically connected to the central control system 9. In this embodiment, the arm 21 is a telescopic arm, so as to further expand the coating range of the automatic putty scraping device.

[0019] The free end of the support arm 23 is connected to a brushing mechanism for coating. Specifically, the brushing mechanism includes a plurality of substrates 3 and a plurality of pins 4 connected in sequence to form an arc-shaped brushing base. Before contacting the surface of the blade to be coated, the brushing base is in a semicircular arc shape. After contacting the surface of the blade, the brushing base will adapt to the changes of the surface curve of the blade, and will also adjust the arc-shaped posture in real time according to the changes of the blade surface curve, so as to better meet the requirements of putty scraping work. The brushing mechanism also includes a plurality of nozzles 6 and scraping rollers 5, and the nozzles 6 are located between the scraping rollers 5. The nozzles 6 are connected to the pump barrel 8 through a delivery pipe 7. The pump barrel 8, the rocker mechanism 2 and the nozzles 6 are all electrically connected to the central control system 9. In this embodiment, the scraping roller 5 is made of rubber material, with a diameter of 40-50 mm and a length of 250-300 mm; the delivery pipe 7 is made of 304 stainless steel, thereby extending the service life of the delivery pipe.

[0020] In addition, the bottom of the support arm 21 of the rocker mechanism is connected to the mobile base 1 through the turntable 11, and the support arm 21 and the turntable 11 are connected through a second pivot mechanism, and the second pivot mechanism is electrically connected to the central control system 9.

[0021] In this embodiment, the first pivot mechanism and the second pivot mechanism are both commercially available products, and both include a motor and a gear pair. The gear pair includes a driving wheel and a driven wheel, the driving wheel is fixed on the output shaft of the motor, the driven wheel is fixed on the corresponding arm, and the motor is fixed on the mobile base 1 or another arm. The central control system 9 can store and retrieve parameters and programs, and control the motor electrically connected thereto through a preset program, thereby controlling the movement of the rocker mechanism for putty coating and the start and close of the nozzle. An electric roller is provided at the bottom of the mobile base 1 to realize the omnidirectional walking ability of the mobile base 1.

[0022] In order to ensure the quality of coating, the automatic putty scraping device also includes a pressure sensor (not shown in the figure), which is connected to the central control system 9 by signal. After the scraping mechanism contacts the blade surface, the pressure sensor obtains the feedback of the contact force to the central control system 9, and the central control system 9 calculates the reasonable pressure size, and then controls the first and second pivot mechanisms in real time to adjust the contact force to ensure that when the blade surface is puttyed, the putty can be stably and effectively scraped on the blade surface without damaging the blade.

[0023] The three-dimensional graphics of the wind turbine blade are input into the central control system 9 in advance. When the blade arrives at the operation area, the mobile base 1 will perform putty coating on the entire surface of the blade according to the industrial control and the corresponding three-dimensional graphics of the blade.

[0024] The technical solutions in this embodiment are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
