Abstract

The utility model discloses a pinion and rack type maritime floating platform wave motor, which comprises at least two groups of wave energy transmission units. Each group of wave energy transmission units comprises a square-shaped float bowl made of a stainless steel material and a square-shaped guide bar fixedly disposed at the central position of the top face of the square-shaped float bowl. Guide rails are arranged on two opposite sides of the square-shaped guide bar and matched with guide grooves disposed outside the edges of a maritime floating platform in sliding mode, and a rack is positioned on the other side of the square-shaped guide bar and meshed with a transmission gear. An overrunning coupler is arranged on the inner periphery of the transmission gear and installed on a power output shaft disposed on the maritime platform. The pinion and rack type maritime floating platform wave motor is simple in structure, good in anti-corrosion property, high in stability of a transmission mechanism and transmission efficiency, low in cost and convenient in maintenance.

Description

Pinion and-rack maritime floating platform wave motor

Technical field

The utility model relates to wave wave energy motor, especially a kind of pinion and-rack maritime floating platform wave motor.

Background technique

At present, energy scarcity, the while is that master's fuel combustion produces bigger pollution, green energy resource to environment with coal stone oil; Like solar energy, outside the wind energy, it is huge, inexhaustible, nexhaustible that the wave wave energy has the energy; Alternative coal, oil, pollution-free, the green characteristics of no resultant.

Existing wave wave energy motor, the major defect of existence: the one, because rotating mechanism and contact with sea water, antiseptic property is relatively poor, safeguards inconvenience; The 2nd, complex structure, cost and maintenance cost are higher; The 3rd, relatively poor in wave effect underdrive mechanism stability, transmission efficiency is not high; The 4th, too dark because of the ocean, fixed offshore platform column cost is too high.

The model utility content

The purpose of the utility model is: provide a kind of simple in structure, antiseptic property is good, and the driving mechanism stability is good, and transmission efficiency is high, and cost is low, safeguards pinion and-rack maritime floating platform wave motor easily.

For realizing above-mentioned purpose, the utility model can be taked following technical proposals:

A kind of pinion and-rack maritime floating platform of the utility model wave motor; Comprise at least two group wave energy gear units, every group of wave energy gear unit comprises the square floating drum of processing with stainless steel material, is fixedly arranged on the square guide rod in said square floating drum end face center portion; Be equipped with guide rail on two relative sides of said square guide rod; This guide rail and the unsettled guide groove that is arranged at outside the maritime floating platform edge are slidingly matched, and on the another side of said square guide rod, are provided with tooth bar, this tooth bar and driving gear engagement; Week be provided with free wheel device in the said driving gear, this free wheel device is installed on the pto that is arranged on the said offshore platform.

As preferably, said wave energy gear unit is two groups, and two groups of said wave energy gear units are symmetricly set in the both sides of said maritime floating platform, the shared pto of the free wheel device of two wave energy gear units.

As preferably, flywheel and speed change gear are installed on the pto between the said driving gear, said speed change gear and generator are in transmission connection, and also are provided with a plurality of bearing spiders that are used for the supporting motive force output shaft at sea on the floating platform.

As preferably, said maritime floating platform is the drill platform that floats, or steamer, or the chinampa.

Compared with prior art the beneficial effect of the utility model is: owing to adopt technique scheme, be provided with two groups of wave energy gear units at least, every group of wave energy gear unit comprises the square floating drum of processing with stainless steel material, is fixedly arranged on the square guide rod in said square floating drum end face center portion; Be equipped with guide rail on two relative sides of said square guide rod, this guide rail and the unsettled guide groove that is arranged at outside the maritime floating platform edge are slidingly matched, and on the another side of said square guide rod, are provided with tooth bar, this tooth bar and driving gear engagement; Week be provided with free wheel device in the said driving gear, this free wheel device is installed on the pto that is arranged on the said offshore platform, and its running is: when wave rose or descend, the said square floating drum that drives a plurality of wave energy gear units alternately floated; The square floating drum of come-up rotates through the rack drives driving gear on the square guide rod, and free wheel device self-locking at this moment drives pto and rotates; When wave descended, under the deadweight effect, the square floating drum descended together with square guide rod and tooth bar; Drive the driving gear backward rotation, at this moment free wheel device separates with pto, this structure of the utility model; The transmission part of conversion wave energy has only several, simple in structure, and the transmission stability when guide rail is resisted stormy waves is good; Transmission efficiency is high, and guide rail is changed easily, and cost is low; It is convenient to safeguard, this structure of the utility model has only the square floating drum of processing with stainless steel material to float over the sea; Antiseptic property is good, and this structure of the utility model is when sea level altitude changes within the specific limits; Need not adjust the height of maritime floating platform, said tooth bar still can with the driving gear engagement driving, floating platform is compared with fixed offshore platform; Can save expense from column to the deep-sea that set up, greatly reduce cost, improve effect; The utility model adopts the square floating drum, and it is big to meet the corrugated, rises floating effective.

The further beneficial effect of the utility model is: on the said pto flywheel is installed, storing energy can rely on self inertia on the other hand on the one hand, and the rotating speed of balanced pto helps driving generator for electricity generation.
