Definitions
- the present invention relates to a safety device or system for wind turbine operations, which allows to ensure a possible robotic unit, scaffolding, carriage or other element that moves through the tower, for maintenance, repair or cleaning, against falls or landslides due to loss of support.
- the invention is preferably applicable in the field of repair and maintenance of wind turbines and similar towers.
- a robotic unit or other mobile element can be applied along the tower, which is supported by its own means.
- a robotic unit or other mobile element can be applied along the tower, which is supported by its own means.
- it since it is maintained at high altitude and in areas of high winds, it is necessary to install safety measures in case you lose grip and slide or fall down the tower to the ground.
- Some crane manufacturers use elements that allow traction on a steel cable located on the slow axis of the wind turbine (the one directly connected to the blades) (for example the TRACTEL TIRAK model) to raise heavy loads from the ground to the gondola or Nacelle
- the invention consists of a security system according to the claims, which offers the advantages outlined. It is a security system that protects both the robotic unit, or any other element that is hoisted next to the tower, such as the nacelle-tower assembly.
- the anchorage of the safety system is carried out directly on the wind turbine chassis, preferably at a lifting point of the nacelle, the one used during its construction, therefore, it is a robust and consistent point which will receive the loads only in sliding case of the robotic unit.
- dynamic loads may be disregarded in the event of a slide since, as will be shown later, the system includes a cable locking system that acts in a very small range of travel, normally less than 50 mm, This allows us to neglect the dynamic loads in case of sliding of the robotic unit of cleaning or maintenance or another element to be secured.
- the security elements may be oversized to ensure their effectiveness in case of sliding for any object.
- the cable can be defined with a minimum breaking load that is several times above the mass of the robotic unit or, in general, of the element to be secured.
- the security system of the invention is based on mechanical simplicity and has taken into account both the safety of the element to be secured, normally the robotic unit, as well as the safety of the tower-nacelle assembly, also facilitating the assembly of the system on site .
- the security system can be mounted by an operator in approximately half an hour.
- the invention corresponds to a safety system for operations in wind turbines of the type that has a nacelle with a lifting point.
- the system comprises a cable fixed at one end to the element to be secured, usually a robotic unit, where said cable is also connected to a counterweight optionally integrated in a hoist. .
- the cable passes through an unwanted movement blocking system of said cable, fixed to the lifting point, and a first pulley, to change the orientation of the cable.
- the blocking system will be the one that stops any slippage of the element to be secured.
- the system will comprise a bushing, for example of polyester, at the point of entry of the cable into the nacelle.
- This bushing may be provided with a removable cover for when the safety system is not installed.
- the counterweight will be installed in a hoist, with two or more branches, to reduce the travel of the counterweight and its distance to the nacelle.
- Figure 1 is included, with a general scheme of the security system described herein, according to a preferred embodiment thereof.
- the safety system for wind turbine operations starts from a gondola or nacelle (1) with a lifting point (2) for mounting the nacelle (1).
- This lifting point (2) is used in the safety system to hold a cable (3) that will be attached to the element to be secured, usually a robotic unit (4), schematically represented, to hold it in the event of a slip.
- That robotic unit (4) may be a robotic unit (4) for cleaning the tower.
- the cable (3) travels through the inside of the nacelle (1) from an entry point (5) at its bottom, to a first pulley (6) and a cable locking system (61) (3) in case of unwanted movement of the cable (3), and of said first pulley (6) to a counterweight (8) of the cable (3).
- This counterweight (8) will preferably hang a short distance from the nacelle (1) to minimize its oscillation at the mercy of the wind. This is preferably achieved by at least one hoist (7). This oscillation is undesirable because it can lead to the counterweight (8) hitting the tower or the robotic unit, or directly introducing vibration to the wind turbine structure.
- the distance and mass of the counterweight (8) will depend among other things on the number of branches in the hoist (7).
- the entry point (5) of the cable (3) in the nacelle (1) can be protected with a bushing (9), for example polyester, which prevents the cable from rubbing (3) with the wall of the nacelle (1) ).
- the bushing (9) may have a cap that closes it when the safety system is removed.
- the entry point (5) will preferably be arranged below the support structure (62) of the locking system (61). This support structure (62) can be used to also support the first pulley (6).
- the hoist (7) will be anchored, for example, in the back door of the nacelle (1).
- the lifting point (2) is fixed to an element of the chassis (10) of the nacelle (1).
- other configurations for example, by providing a plurality of pulleys through which the cable (3) runs) are equally possible within the object of the invention.
- the union of the cable (3) to the robotic unit (4) implies that, with the rise of the latter through the tower, the cable (3) is collected thanks to the counterweight (8) remaining tense.
- the counterweight (8) will advance less than the robotic unit (4) thanks to the hoist (7). Thus, if it is of the type depicted in Figure 1, with two branches, half will advance. Keeping the cable (3) tense by means of the counterweight (8) helps the robotic unit (4) to work in optimal conditions.
- the locking system (61) of the cable (3) which has been shown close to the first pulley (6), is an essential element of the invention, since it is the one that really slows the sliding or lifting of the robotic unit (4). ).
- This locking system (61) can be made, for example, of a "Blocstop” (registered trademark) equipment marketed by the company Tractel, together with the support structure (62) of the first pulley (6).
- Other commercial locking systems (61) can be applied, such as that indicated in patent ES475700, also of Tractel. These locking systems detect the loss of tension in a cable, or the large increase in speed, and proceed to fix it in position.
- the locking system (61) will brake the cable (3), transmitting the robot's own loads to the lifting point (2) of the nacelle (1).
- the robotic unit (4) will only need a very short cable run to stop completely (for example, a maximum of 50 mm with the locking system (61) described above). Therefore, the final position in case of sliding will be practically the same as before sliding.
- the first pulley (6) and / or one or more guides of the cable (3) will preferably have anti-skid means to confine and secure its path in the system, preferably comprising one or more plates that keep the cable (3) on the stand. of the first pulley (6), or other means known in the state of the art.
- the system of the invention allows having one end of the cable (3) fixed to the robotic unit (4) without the need for the cable (3) to be through (this will avoid damaging the hydraulic hoses).
