Description

Folding tower

Technical field

The present invention relates to tower supporting construction and the method that is used to make the tower supporting construction upright.

Background technology

In polytype landform, typically by with wind turbine with ground at a distance of a certain height place location with remain to and gather in the crops wind-force in the wind.In order to realize that like this tower structure of standing vertically is used to install rotor and the hanging basket that produces power.Wind turbine typically is installed in wheel hub center height (hub level) and locates to have in the zone of neat horizontal line of sight, and is distinguished and admirable in the blade of wind turbine to allow, and produces air whirl at least by surrounding environment.

The tower structure that is used for wind turbine be configured to adapt to and stand wind turbine assembly weight, act on wind-force on the wind turbine blade and on the tower, by the caused pressure of change of the direction of the wind turbine blade of spin, by the caused vibration of the aerodynamic force on the blade with by the caused vibration of wind turbine rotating mechanism.In addition, the tower structure that is used for the wind turbine of horizontal axis is configured to be applicable to and can be used for the method that makes assembly upright.Crucial tower is installed Consideration and is comprised following factor, that is: safety is avoided the damage of wind turbine, and the restriction cost of installation, for example uses hoisting crane and concrete cost.

Past has used polytype tower to support the small-scale wind turbines that produces electric power.Under the situation of the tower of guyed tower, acclivitous tower and these three kinds of general types of self-supporting tower, the supporting tower that is used for the wind turbine of horizontal axis can be a connected to chassis.Tower structure can typically be configured with grid, truss and tubular assembly.Before the upright processing of beginning, tower is assembling on the ground typically.

Guyed tower typically is used for small-scale wind turbines.Guyed tower can be equipped with hoisting crane, and described hoisting crane is in tensioning and fixedly promote the stack-mounted tower to the position of standing before the backguy.Guyed tower can also uprightly play one section in the situation of not using hoisting crane next time.The interim arm that extends beyond the top of tower is used to promote next tower section, and promotes small-scale wind turbines or other top installed device at last.Guyed tower needs the space path of broad to be used for the anchoring backguy near the pedestal of tower.

Acclivitous tower is at ground level place pivotally attached tower, and can be fallen with execution and be installed in maintenance on the equipment on the top of tower.Typically, wind turbine and tower fit together when tower is positioned on the erecting bed ground of living in.Use is positioned at the cable at the top that is attached to tower with pulling away from the capstan winch or the heavy-duty vehicle of a certain distance with the pedestal of tower and promotes tower, and the gin pole of pivot is delivered to initial horizontal force in the vertical lifting piece.During upright the processing, often need the cross motion of drag-line with the restriction tower structure.

The self-support type tower is the structure of supporting oneself, and often pre-on the ground assembling of the structure of described self-support and use crane lifting are to the position of erectting.Wind turbine can be installed and promote by tower, perhaps can promote individually and be positioned at then on the top of tower.In case tower is upright, tower is no longer fallen usually.Built-in ladder provides path for the equipment on the top of tower.The tower of supporting oneself normally heavier and be expensive.

Though some notion that proposes in above referenced patent and prior art has been set forth: the needs that help the installation on the structure of tower and upright and wind turbine is in tower structure in the installation site the top; Such as the complexity of tower structure, the other factors of reliability; And the needs that need the goliath of careful examination.In rugged environment, in the approaching typically remote-controlledly zone of snow, ice or the dirt that on comprising flexible, that slide and structural constituent classification of track, occurs, the rise of tower and fall normally challenging.The burden and the cost that use particular outer structure or bigger bont or vehicle to add fitting operation.Generally speaking, tower structure and the upright method of tower that is used for wind turbine application are added complexity by the structure of giving tower and elevator system and are developed.

Though non-flexible acclivitous tower helps near the equipment that is positioned at the upper end of tower structure, but do not need to be used to make the upright hoisting crane of tower to the position of standing, the acclivitous tower of general-duty comprises the pivot of long structure, it is motor-driven to mean that at the equipment load of the upper end of the structure of described length mono-promotes, and described mono-promotes motor-driven whole wind turbine and the tower assembly of putting down in risk.Therefore the use of acclivitous tower is limited to small-scale wind turbines usually.

Repeatedly attempted reducing the cost of wind turbine tower, but also do not realize the coml success, this is that the gin pole that described tower is used for tower lifting and anchor fixes backguy because be difficult to reduce the cost of acclivitous tower, single-column guyed tower or lattice tower.These towers do not need to be used for the cement concrete of ground, and typically are used for the steel plate of column foot seat.Yet because the increase of the size of turbo-machine and the increase of tower height degree, the load that promotes the point of tower by gin pole increases and becomes and can not carry out, and hoisting crane is used to install tower, and cement concrete is used for ground.

Usually, reducing the cost of energy of the wind turbine that is used for the tower under 150 feet or the best way of COE is the height of rising tower.Too simplifiedly, what ratio of the COE energy that to be the turbo-machine cost produce with annual turbo-machine.Higher tower is benefited from the wind speed of increase and importantly than pulsation-free wind, describedly not only allows turbo-machine to operate more effectively than pulsation-free wind, but also increases the life-span of turbo-machine.Power in the wind along with wind speed cube increase and increase, thereby and the tower height degree increase to 100 feet from 50 feet and will typically cause power increase to surpass 50%, but the cost of installation of wind turbine only increases about 11%.What this cost of 11% increased almost all is because the ground and the tower of expensive tower, tower are upright.Helping wind turbine will be to promote the tower height degree in the key factor that becomes feasible more frugally in the future.

Another trend in the wind turbine industry is to trend towards bigger wind turbine.The two has reduced CEO to bigger wind turbine for small turbomachine (1kW-100kW) and utility grade turbo-machine (1MW+).Typically, embodiment disclosed herein will maximize reducing of CEO for 5kW to the small turbomachine of 100kW.Below about 5kW, can be at the ground that does not have under the concrete situation design tower, and can use gin pole that tower is inclined upwardly.More than 100kW,, need to be used for the cement concrete of ground and between the tower installation period, to need hoisting crane by bigger top of tower thrust loading that rotor produced and their bigger quality.
