Description

Wind power tower anchor assembly and wind power tower anchor foundation

Technical Field

The utility model relates to an anchoring assembly and an anchoring foundation, in particular to a tower anchoring assembly and a tower anchoring foundation of a wind driven generator, and belongs to the technical field of design and manufacture of the tower anchoring assembly and the tower anchoring foundation of the wind driven generator.

Background

The wind driven generator is an electromechanical integrated device for converting wind energy into electric energy, and the power generation process has the characteristics of environmental protection, green and regeneration and the like.

Wind power generation generally requires a generator set, a tower and a fan blade, wherein the tower is anchored on a foundation to support the generator set, the fan blade is arranged on a rotating shaft of the generator set to receive kinetic energy of wind for rotation, and the rotating fan blade drives a rotor of the generator set to rotate so as to generate current.

Because the wind blades rotate to generate huge torque, and the weight of the generator set, the wind blades, the tower and the like is finally concentrated on the anchoring foundation of the tower, the wind power generation not only needs a solid and stable foundation entity, but also needs a set of anchoring components meeting the requirements and matched with the foundation entity to form the anchoring foundation of the tower of the wind power generator together, thereby providing guarantee for the work of the wind power generator set.

The wind power tower anchoring assembly in the prior art mainly comprises an upper anchor plate, a lower anchor plate, anchor bolts and the like, wherein the anchor bolts are rigid structural members, usually steel columns, and are connected between the upper anchor plate and the lower anchor plate through nuts to form an anchor cage structure; the foundation entity used for anchoring the wind power tower is usually a gravity bearing platform formed by pouring reinforced concrete. In the construction process of the gravity bearing platform, the anchor cage structure is preset between the steel reinforcement frameworks of the gravity bearing platform, and then concrete is poured to form an integrated tower anchor foundation of the wind driven generator, for example: the utility model relates to a tower foundation anchor bolt assembly and a tower foundation (application number: 201720883238.2), an anchor bolt foundation of a wind generating set (application number: 201320446319.8), a ground anchor cage foundation convenient to replace and overhaul (application number: 201720144772.1), a replaceable prestress anchor bolt mechanism (application number: 201720144775.5), a wind generating set foundation and a replaceable anchor bolt cage (application number: 202223308688.9) and the like.

Although the rigid anchor bolt has good strength and can generate the stress required by the anchoring of the wind driven generator tower, the rigid anchor bolt has the defects in the installation process, as described in the background art of the specification of the utility model patent of the basic structure of a wind driven generator set and the wind driven generator set (application number: 201922062457.6): because the crab-bolt is rigid structure, when installing the last anchor slab of crab-bolt basis, the last anchor slab of crab-bolt basis can support on the crab-bolt through upper and lower portion nut, but every crab-bolt of current crab-bolt basis is rigid structure, is difficult for aligning with the mounting hole on the upper and lower anchor slab when wearing to locate it about the anchor slab, influences installation effectiveness, consequently, this patent proposes the technical scheme that provides tensile for the tower through the anchor rope of flexible anchor rope replacement rigidity.

Furthermore, rigid anchors have disadvantages during the replacement process, as indicated in the background art of the invention patent application "anchoring Assembly based on Fan Foundation fixing and method for fixing thereof" (application number: 202310292644.1): when the anchor rod (namely a rigid anchor rod) has a quality problem, the anchor rod is relatively long in structure, the space between the tower and the fan foundation for replacing the anchor rod is relatively narrow, the anchor rod is relatively troublesome to replace, and the anchor rod influenced by a platform in the tower and a tower door frame can not be replaced; for this purpose, the patent application also proposes an improved solution for replacing rigid anchors with flexible anchor cables.

However, in practice, it is found that although the flexible anchor cable can overcome the defects caused by the rigid anchor bolt in the process of installation or maintenance and replacement, the existing technical scheme of adopting the flexible anchor cable to replace the rigid anchor bolt has certain defects in the process of installation, maintenance and replacement, and the concrete steps are as follows:

First, the installation is inconvenient. Because the anchor rope is flexible, can not support fixedly and leveling as the support component to last anchor slab when constructing the anchor cage, so must use interim rigid support component to support fixedly and leveling to last anchor slab temporarily, and after the gravity cushion cap is pour, interim rigid support component just loses use value, both extravagant material, increase cost again, if demolish, then waste time and energy, can not be refund, and still probably damage its intensity to the gravity cushion cap in demolishment process.

Secondly, replacement is inconvenient. As anchor pieces of the tower, an anchor bolt or an anchor rope is generally provided with stress by adopting a post-tensioning method, so that the pre-embedded anchor rope is usually tightly connected with concrete of a gravity bearing platform, although PE (polyethylene plastic) sleeves are sleeved on the anchor rope to prevent the anchor rope from being adhered with the concrete, the anchor rope is not in ideal linear arrangement in the gravity bearing platform due to disturbance of the process of vibrating the concrete and the like in the manufacturing and construction process, and certain pressure is applied to the outer wall of the PE sleeve due to the fact that the fluid form is adopted before the strength of the concrete is generated, so that the PE sleeve and the anchor rope are in a tightly attached state, the replacement difficulty of the anchor rope is increased, and the anchor rope sometimes has to be reamed to be installed in place to finish new anchor rope, so that a large amount of manpower and material resources are consumed.

On the one hand, when the sleeve is used as a supporting, fixing and leveling component of an upper anchor plate in the process of manufacturing a wind power tower anchoring foundation, certain strength is required and the whole length of the sleeve needs to be adjusted, so that the sleeve can meet the requirement by arranging the sleeve to comprise a main pipe fitting made of hard rigid materials and a port piece which can be arranged on a port of the main pipe fitting and is used for adjusting the whole length of the sleeve;

On the other hand, when the anchor cable is tensioned, pressure is applied to the sleeve, if the sleeve is entirely made of hard rigid materials, the sleeve is possibly bent and deformed or even broken, so that the function of the sleeve is influenced, and when the sleeve is changed into a main pipe fitting made of the hard rigid materials and a port fitting which can be arranged on a port of the main pipe fitting and used for adjusting the whole length of the sleeve, the port fitting can be used for adjusting the whole length of the sleeve so as to eliminate the pressure applied to the sleeve when the anchor cable is tensioned, and the sleeve is ensured not to be deformed or broken when being pressed, so that the function of the sleeve is ensured to be intact.

Alternatively, as shown in fig. 4, a schematic cross-sectional structure of a sleeve pipe formed by a main pipe and a port in a wind power tower anchoring assembly according to an embodiment of the present utility model is shown:

One end of the port member 132 is connected with the upper plate anchor hole 111 and/or the lower plate anchor hole 121 through an external thread thereof, and the other end of the port member 132 is provided with a tapered structure and is provided with a longitudinal slit so that the port member 132 can be inserted into the main body pipe member 131 and can be retracted and extended at the port of the main body pipe member 131 under the action of external force, thereby adjusting the overall length of the sleeve 130.
