Detailed description of the invention:
All-round deep water tide current power generation station, in force according to being divided in the set-up mode difference in marine site: the all-round deep water tide current power generation station of free type and fixed all-round deep water tide current power generation station.
All types of all-round deep water tide current power generation station, all by float electric generating station unit, floating current stabilization canal or speed change floating current stabilization canal, anti-dive disappear that wave is floating, suspend disappear unrestrained device and fixing hawser, spud pile short wooden stake and fixing pendant etc. of suspension wave eliminating bank and monomer form.
Float electric generating station unit, as shown in a, b, c in Fig. 1, forms primarily of the current stabilization canal 2 of power station machine room 1, float electric generating station unit and waterwheel engine 3.
Power station machine room is as shown in b, c in Fig. 1, and preferably semicircle or triangle, because semicirclely can effectively to dissolve with triangle and the attack of low wind and wave resistance, increases safety factor.In the marine site that main air wave direction ratio is comparatively fixed, allow leg-of-mutton one jiao to meet to main air wave, effectively can dissolve the attack of stormy waves, semicircular room body also well can dissolve the attack of wave.Certainly, disappearing under unrestrained self-contained prerequisite, the power station machine room of other shapes is also feasible.Power station machine room respectively Symmetric Composite, in the current stabilization canal canal bridge wall both sides of float electric generating station unit, also can be current stabilization canal be integrally with two generator room.By in Fig. 1 shown in a, b, c, in each machine room waterwheel engine power transmission shaft on a set of change-speed gearing (group) 12 is respectively installed, change-speed gearing (group) is connected with gearbox 13, and gearbox docks with generator 4; Due to the flow velocity of tide ocean current, determine that the rotating speed of waterwheel engine is generally per minute is no more than 50 turns, (the tide flow velocity that Weihai one is with, generally to turn left the right side at 10-20 per minute), some sea areas due to trend comparatively slow, make the rotating speed of waterwheel engine also not reach 10 turns, so, make the rotating speed of waterwheel engine reach the rated speed of generator, change-speed gearing (group) just must be installed, the rotating speed of waterwheel engine be become the rated speed of generator; Due to the cyclically-varying of celestial body gravitation, and make the flow velocity of tide ocean current, every two weeks produces once from the flow velocity from fast to slow process of flood to dead flood of living, or from dead flood to the flow velocity of flood of living by the cycle period of the process that accelerates slowly, so, want the rotating speed making generator, specified rotating speed can be reached in whole cycle period, just gearbox must be installed, the effect of gearbox is: by from live flood to dead flood or from dead flood to live flood the whole tidal period in, the different rotating speeds of waterwheel engine becomes the necessary rated speed of power station unit; Gearbox can be manual transmission, also can be automatic gear-box.Corresponding two the float electric generating station machine rooms of waterwheel engine, are arranged on the waterwheel engine support 5 on the current stabilization canal canal bridge wall of float electric generating station unit.
With the current stabilization canal canal bridge wall 6 of the float electric generating station unit of power station machine room Symmetric Composite, there is certain width, generally be no less than 1 meter wide, not only to reach and can definitely support waterwheel engine, also will as the movable corridor of waterwheel engine line service, the current stabilization canal canal bridge wall of float electric generating station unit exposes the height on sea level, the marine site that will arrange according to all-round deep water tide current power generation station, contingent fully developed sea and determining, it is generally acknowledged and the contingent fully developed sea in marine site is set, add 1.5 meters, it is exactly the desired Safety height that the current stabilization canal canal bridge wall of float electric generating station unit exposes sea level, have enough wind and wave resistance to make waterwheel engine and attack ability.The current stabilization canal canal bridge wall of float electric generating station unit in the cohort of deep water tide current power generation station the height on sea level all can be exposed, can be suitable less, because all-round deep water tide current power generation station cohort, supporting have the sound unrestrained facility that disappears, and can eliminate the attack of any wave.The current stabilization canal canal bridge wall of float electric generating station unit submerges the degree of depth on sea level, consistent with the specification of floating current stabilization canal delivery port, and the current stabilization canal water inlet of float electric generating station unit is equal large mutually with the delivery port of floating current stabilization canal or the floating current stabilization canal of speed change.Because the height of the current stabilization canal canal bridge wall of float electric generating station unit is larger, the power transmission shaft 9 between waterwheel engine and generator is just caused also to be in higher position, thus generator will be arranged on the position consistent with power transmission shaft height, so, power station machine room just to have had at the bottom of double-deck machine room 7, effectively can improve the safety leak-proof coefficient of power station machine room at the bottom of double-deck machine room.
At the current stabilization canal canal mouth of float electric generating station unit, more than tide ocean current horizontal level, across the canal bridge wall of current stabilization canal, at the forward and backward reinforcing watertight shutter 8 adding certain altitude respectively of waterwheel engine, play the width controlling current stabilization canal, the effect strengthening current stabilization canal intensity, and stop in current stabilization canal tide ocean current excessive; The height reinforcing watertight shutter can be contour with the current stabilization canal canal bridge wall of float electric generating station unit.The drive plate of the reinforcing watertight shutter dried up car engine on float electric generating station unit current stabilization canal is closer as far as possible, generally between 10-20cm, is conducive to the regular maintenance of staff to waterwheel engine like this.Bottom the current stabilization canal of float electric generating station unit, preferably totally enclosed, because totally enclosed structure is firmer.The cross section of the current stabilization canal of float electric generating station unit, as shown in a, b in Fig. 3, can be rectangle, also can be bottom semicircular, Upper rectangular; Certainly other shapes is also passable, but for the drive plate of waterwheel engine, rectangle the simplest with the drive plate manufacture craft of bottom semicircular, Upper rectangular, and utilization rate is the highest again.
