Description
Technical field
The present invention relates to the foundation structure of marine power generation blower, the basis knot of especially a kind of submerged floating marine power generation blower
Structure.
Background technique
With development of world economy, demand of the mankind to the energy is continuously increased, and by non-renewable energy resources exhaustion and environment
The pressure of protection, green regenerative energy sources have obtained developing on a large scale very much, especially wind energy.In recent years, with land wind energy resources
A large amount of exploitations and land wind energy utilization are restricted, such as shadow pollutes, noise pollution, and the exploitation of wind energy resources is gradually
It is marine by land steering, and the rapid development of marine wind energy resources and technology abundant, it provides and fills for the development of ocean wind-powered electricity generation
The condition divided.
And for shallow sea profundal zone, the offshore wind turbine foundation of floatation type is generally used, floatation type offshore wind turbine foundation is general
It is divided into Spar formula, semi-submersible type and tension leg type, but no matter uses the basis of which kind of form, the height of blower is substantially solid
Calmly, blower is understood fan blade be arranged to obtain and is compared to obtain better air quantity in the case where normal weather to generate electricity
It is higher, in this case if encountering typhoon weather, since the front face area of fan blade is larger, suffered by wind load meeting
It is bigger, and because torque caused by the excessive height of fan blade is larger, the anchor of blower foundation is extremely easy because of stress
The uneven or overtension that bears and broken, or there is weak area in anchor pile at sea bed, so as to cause toppling.
Perhaps cause blower impaired due to encountering its Blower Body of rare Super Typhoon or blade intensity deficiency.
In order to overcome the above problem, applicant devises a kind of marine power generation blower of formula that snorkels, marine power generation blower
On floating drum, floating drum bottom is anchored by ground tackle, can be driven under floating drum under the poor harsh weather of sea situation
It is latent, power generation fan height, which is reduced, to avoid the overload of blower improves the safety of power generation fan.
However, the anchor pile for only relying on the anchor chain connection seabed of bottom is realized, in lifting process due to the anchoring of its floating drum
In, floating drum is easy to be influenced by wave load, and the stability of floating drum is poor in lifting process, holds in the biggish situation of wave
It easily swings, meets the weather of high wind wave, every cable stress unevenness can be made, be easy to appear the case where hawser overload is snapped, band
Come dangerous.
Utility model content
The utility model, which provides one kind, can make submerged floating marine power generation blower more stable sea in lifting process
Upper power generation fan foundation structure.
A kind of marine power generation fan foundation structure, the floating drum including floating on sea, the fan main body on floating drum, and drive
The elevating mechanism of buoy lifting is moved, clump weight is provided with immediately below floating drum, multiple anchors are arranged in the seabed of the periphery lower section of floating drum
Gu stake is arranged multiple fixed pulleys in the bottom symmetrical of floating drum, is correspondingly arranged hawser, each hawser one end system and counterweight on each fixed pulley
On block, around after fixed pulley, the other end is lain on corresponding anchor pile.
Marine power generation fan foundation structure described in the utility model can follow buoy lifting by being arranged below floating drum
Clump weight, increase the weight of marine power generation blower, avoid it in lifting process by wave load and wind load
It influences, is not easy to swing, since the symmetrical centre that clump weight is in each hawser avoids certain so that every cable stress is uniform
Hawser snaps because of excess load, while reducing the center of gravity of floating drum, improves the stability and reliability of blower lifting.
Detailed description of the invention
Fig. 1 is the infrastructure diagram of the marine power generation blower.
Specific embodiment
As shown in Figure 1, the waterworks 58 of elevating mechanism include the water inlet 57 for being set to 51 bottom of floating drum, and control
The solenoid valve 581 that water inlet 57 is opened and closed, drainage arrangement 56 include draining pump 561, and the water inlet pipe of draining pump 561 is connected in floating drum
Chamber, entrance are located at the bottom of floating drum inner cavity, and the drainpipe of draining pump 561 is then communicated with floating drum outside.Its 51 top of floating drum with
The partition 55 of blower joint setting, the draining pump 561 being arranged above the partition 55 in blower rack.
Drainage arrangement 56 and waterworks 58 are powered by the battery 59 being set in fan body rack 54.Anchoring machine
Structure 6 includes hawser 61, and 61 one end of hawser is anchored in the anchor pile 62 on sea bed, and the other end is connected with floating drum 51.
The liquid level sensor 52 that control waterworks 58 stop working is provided in floating drum 51, when liquid level reaches setting value
When, liquid level sensor 52 controls drainage arrangement 56 and stops working.
It is provided with the pressure sensor 53 that control waterworks 58 stop working in floating drum 51, is reached when bottom is hydraulic in floating drum
When to setting value, 53 action control drainage arrangement 56 of pressure sensor stops working.
Anchoring mechanism 6 includes being set to 51 bottom symmetrical of floating drum to be provided with multiple fixed pulleys 63, is set to the multiple of seabed
Anchor pile 62 and fixed pulley 63 correspond, and 61 one end of hawser is anchored in anchor pile 62, and the other end passes through fixed pulley 63 and setting
Clump weight 64 under floating drum 51 connects, and when elevating mechanism control system receives sinking instruction, solenoid valve 581 is opened, seawater into
Enter floating drum 51, the sum of blower self weight and the weight of seawater are greater than buoyant of sea water, clump weight 64 and blower slowly sink down into buoyancy with
The position of blower overall weight balance reduces violent typhoon weather to the damage probability of fan blade.When receiving climb command, draining system
System starting, buoyancy gradually increase, and clump weight 64 and blower slowly rise, and restore power generation.The clump weight 64 is used for auxiliary float 51
Stablize sink, thus keep blower anchor stability.
For anchor pile 62, either squeezing into the pile body of sea bed, it is also possible to gravity block as shown in Figure 1, makes it
Deeper sea area is adapted to, the difficulty of seabed piling is reduced, while also adapting to softer sea bed.
Its multiple gravity block is connected, and forms ring structure, multiple anchor points is symmetrical arranged in ring structure, with floating drum bottom
Multiple fixed pulleys 63 correspond, be correspondingly arranged hawser 61 on each fixed pulley 63, in each 61 one end system of hawser and clump weight 64,
After fixed pulley 63, the other end is lain on the anchor point of ring structure, since blower is located at the center of annular gravity block, can be kept away
Fan-free is when bearing larger wind load, since friction is small and leads to blower dragging gravity block drift for riverbed and gravity block
It moves.
For clump weight 64, ring structure can be used, to reduce clump weight 64 in the resistance of lifting process weight.
Position limiting pile in the looping pit of the seabed setting insertion clump weight 64 of 64 bottom of clump weight, it is horizontal to reduce clump weight 64
To the amplitude of swing, keep the center of gravity of blower more steady.
