Description

Scaffolding tower, wind turbine repair-cleaner wind power

Technical sector

The invention is part of the procedure technician by which the tasks of maintenance, repair, cleaning and all the jobs that were needed on the wind turbine blades through of a basket that will carry the specific elements and devices necessary for each job, as well as the technicians who they will use, if necessary.

This basket is attached to one arm robotized, which is inside an element structural, which is responsible for the displacement of the arm roboticized through the scaffolding tower.

State of the art

Due to the need to keep optimal wind turbine blades conditions and for their high repair cost in general, is what we believe necessary the technique that after the current one, we will describe.

Several are known today procedures by which the work of maintenance, repair and cleaning of the blades of the Wind turbines.

Once the repair decision is made, maintenance or cleaning, the Aspa is lowered to the ground, by means of several large tonnage cranes, which must arrive from the base of the wind turbine to the blade anchor, to detach it from the rotor of the wind turbine.

It is obvious to understand that this process leads to out after stopping said wind turbine to be able to lower the blade down.

The work also has to be developed with very high disassembly and assembly costs, in addition to the rental of the cranes, also rigging the decrease in productivity energy of the wind turbine. The blade once on the ground is repaired, replaced or cleaned according to the anomaly found, being the average time used in this process (depending on the problem), ranges between 5 and 14 days. So wasting time and necessary material in these works are very high, if compared with the procedure carried out by our invention.

With our invention the technicians would move that would perform the appropriate work to solve the different anomalies found (not to mention the decrease in possible associated risks, for not having had Preventive maintenance), getting a true cost reduction given the greater wind turbine hourly performance by not having to Being idle for so long.

These sections (19) (Fig. 5) of the scaffolding tower (1) will be hoisted by the motors (26) (Fig. 4) located at the head of the base (24) (Fig. 2) (Fig. 3) (Fig. 4) of the scaffolding tower (1) (Fig. 1), by means of the rack system (16) (Fig. 5).

The sections (19) (Fig. 5) that are introduced in the base (24) (Fig. 2) (Fig. 3) (Fig. 4) of the scaffolding tower (1) (Fig. 1), as well as the base (24) (Fig. 2) (Fig. 3) (Fig. 4) of the scaffolding tower (1) (Fig. 1), are composed of a structure 7.5 meter high quadrangular metal, which is located closed (42) (Fig. 5) on three sides and being part of a open side (43) (Fig. 5). At the ends of these sides we we will find cylindrical tubes (44) (Fig. 5) that will facilitate the step and help us stiffen the structure of the scaffolding tower (1) (Fig. 1), to the working step of the displacement system (12) (Fig. 6) of the robotic arm (13) (Fig. 7) (Fig. 8).

The inner corners (45) (Fig. 5) and exteriors (46) (Fig. 5) of these sections are of structure cylindrical; the outer cylindrical corners (46) (Fig. 5) we they serve so that on them they can turn the 12 convex wheels (17) (Fig. 4) that has the corners of the base coupled (24) (Fig. 2) (Fig. 3) (Fig. 4) of the scaffolding tower (1) (Fig. 1) which are They are coupled to a rectangular structure.

The sections (19) (Fig. 5) introduced lead in its left and right sides inserted a double zipper (16) (Fig. 5) which is the one that will be used for its elevation.

In addition, these sections (19) (Fig. 5) have internally a zipper (16) (Fig. 5) on the left side and right which is the one that serves to be able to move the displacement structure (12) (Fig. 6) of the robotic arm (13) (Fig. 7) (Fig. 8).

The first section (25) (Fig. 3) that will be lifted by the inside of the base (24) (Fig. 2) (Fig. 3) (Fig. 4) of the tower Scaffolding (1) (Fig. 1), is already located inside it. (Fig. 2) (Fig. 3).
