Description

Module combined type vertical shaft tidal directly driving type electricity generating device

Technical field

The utility model belongs to regenerable marine energy and utilizes technical field, relates to a kind of module combined type vertical shaft tidal directly driving type electricity generating device.

Background technique

Tidal current energy generating equipment is installed on the sea, experience according to ocean engineering, the cost that offshore construction is installed accounts for nearly 50% of assembly of devices basis, wherein major part is a pontoon crane, floating pile driver, the cost of use of engineering ships such as transport barge, these expenses were calculated by the offshore construction contents of a project and operating time; In device service life in the time limit, after breaking down, overhaul and safeguard also and will use the marine engineering ship that these all can make the total life cycle cost increase.

Therefore,, just should note adopting convenient structural type of installing in the design phase of tidal current energy generating equipment, the offshore construction when managing to simplify the tidal current energy generating equipment installation, and shorten the marine operating time, can significantly reduce the installation expense.Simultaneously, adopt simple in structurely, the device that the long-time running reliability is high, reduces maintenance and maintenance cost in the total life cycle at the Mean time to failure of extension fixture.

Summary of the invention

The purpose of this utility model provide a kind of simple in structure, move high efficient and reliable, be convenient to the module combined type tidal current energy generating equipment of installation and maintenance, solving existing trend can the apparatus structure complexity, difficulty is installed, safeguard the problem of inconvenience.

Principle of the present utility model is: whole device directly drives generator, removable framework, jacket pile foundation four module by vertical pivot turbo machine, disc type and forms.The vertical pivot turbo machine adapts to trend and flows to variation, and is simple in structure, easy to manufacture; The direct drive generator generating efficiency does not need gear speeder up to 90%, operational reliability height, and conventional generator for electricity generation efficient about 70%.Vertical pivot turbo machine and direct drive generator integral installation at one movably on the framework, are formed the core cell that trend can device; The jacket pile foundation is installed in the sea at first, and core cell is installed on the jacket pile foundation by coupling member again.

The technological scheme that the utility model adopted is:

A kind of novel plug formula vertical shaft tidal directly driving type electricity generating device, whole device directly drive generator, removable framework and four modules of jacket pile foundation by vertical pivot turbo machine, disc type and form.

Module one, the vertical pivot turbo machine adopts the prismatic blade at fixed installation angle; The cage type blade rack has improved the structure strength and stiffness, the ring card stop fluid along the blade exhibition to flow, reduce induced drag, improved the hydrodynamic performance of blade; The additional drag blade makes turbo machine realize self-starting easily when hanging down flow velocity.

Magnetic pole and iron yoke that module two, disc type are directly driven generator are arranged on the disk rotor, arrange winding on the ring stator, stator is installed on the generator casing, shell forms the seal space of generator bay, and rotor transmission shaft passes generator bay, and links to each other with main turbine shaft by coupling;

Module three, removable base of frame leg are inserted in the sleeve of jacket pile foundation, and removable framework upper end is fixed on jacket pile foundation top by pin, directly drives generator and is fixed on removable base of frame by flange plate;

Module four, the jacket pile foundation is the supporting structure of whole device, piling is fixed on the seabed, all the other each modules all can assemble the back integral hoisting on land and be fixed on the jacket pile foundation, when needing repair and maintenance, turbo machine, directly drive after core cell integral body that generator forms together with removable framework hangs emersion water, on working boat or the land carry out upkeep operation.

Effect of the present utility model and benefit are: apparatus structure is simple, and is reliable, the energy conversion efficiency height has significantly reduced the marine workload of installation and maintenance, and the lifetime overall cost is descended greatly, improved the economic benefit that trend can commercial development.
