As shown in fig. 1 to 4, the present utility model provides a wind turbine tower structure 10 including a carrying platform 11 and a tower body 12.

The carrying platforms 11 are provided in plurality, and the plurality of carrying platforms 11 are used for being inserted into the seabed layer. It will be appreciated that since offshore wind power is installed offshore, to enable wind turbine tower structure 10 to stand on the sea, a layer of seabed soil is inserted through bearing table 11 to ensure structural stability, avoiding collapse of wind turbine tower structure 10 due to the flow of seawater. Specifically, in the present embodiment, a plurality of insertion rods 111 are disposed on each carrying platform 11, and tight connection with the seabed is achieved through the plurality of insertion rods 111, it can be understood that, due to the larger outer diameter of the carrying platform 11, the engineering difficulty can be reduced and the reliability of the engineering can be improved on the premise of ensuring the connection tightness of the seabed soil layer by inserting the plurality of insertion rods 111 with smaller outer diameter into the seabed layer as compared with inserting the carrying platform 11 with the larger outer diameter into the seabed soil layer.

The tower body 12 includes a lower tower 121 and an upper tower 122, the lower tower 121 includes a plurality of columns 1211, bottoms of adjacent two columns 1211 are far from each other, tops of the adjacent two columns are close to each other to form a tripod 1212, and lower vertexes of the plurality of tripods 1212 are connected to each other to form the lower tower 121. Here, we refer to one vertex at the top of the tripod 1212 as an upper vertex and two vertices at the bottom of the tripod 1212 as lower vertices, specifically, in this embodiment, the plurality of the tripod 1212 are vertically enclosed with each other and are drawn toward the middle to form a prismatic table structure, the top of which is placed on the upper tower 122. It will be appreciated that, since the triangle has stability, and the lower tower 121 is formed by the plurality of triangular frames 1212, the stability of the lower tower 121 is high and the structural strength is high, and meanwhile, the triangular frames 1212 are formed by splicing the two upright posts 1211, so that the lower tower 121 only needs to install and transport the plurality of upright posts 1211 when being installed and transported, and the difficulty of installation and transportation is reduced. Further, the lower vertex of the tripod 1212 is fixed on the carrying platform 11, and in this embodiment, two lower vertices of the tripod 1212 are respectively disposed on two spaced carrying platforms 11, and it is understood that the lower tower 121 can be fixed on the sea surface by connecting the tripod 1212 with the carrying platform 11.

The upper tower 122 includes a plurality of support rods 1221, the plurality of support rods 1221 being connected to upper vertices of the plurality of tripod frames 1212, the upper tower 122 being configured for mounting the wind turbine 20. Specifically, in the present embodiment, the wind power generator 20 is mounted on the top of the upper tower 122, and the plurality of support rods 1221 are drawn toward the middle and connected to the upper vertices of the plurality of tripods 1212 in a one-to-one correspondence.

Further, the vertical column 1211 is inclined at a larger angle in the vertical direction than the support rod 1221 is inclined at. Specifically, in the present embodiment, since the plurality of columns 1211 are drawn toward the middle to form the lower tower 121, the plurality of support rods 1221 are drawn toward the middle to form the upper tower 122. Based on the force analysis, it can be understood that the reaction of the vertical post 1211 applied by the bearing platform 11 is upward along the direction of the vertical post 1211, and when the inclination angle of the vertical post 1211 is larger, the larger the gravity that the lower tower 121 can bear, that is, the load bearing requirement of the heavier wind turbine 20 and the upper tower 122 can be satisfied, accordingly, the wind turbine 20 can be set larger to bear larger wind force, and the length of the supporting rod 1221 can be set longer, so that the wind turbine 20 can be installed at a higher height.

Further, the lower tower 121 is heavier than the upper tower 122. It will be appreciated that because lower tower 121 is located at the bottom of upper tower 122, designing the mass of lower tower 121 to be heavier can result in a lower center of gravity for wind turbine tower structure 10, which can improve the stability of wind turbine tower structure 10.

It can be appreciated that the wind power generator tower structure 10 of the present utility model is stably connected with the seabed soil layer through the bearing table 11, the lower tower 121 is set with a larger inclination angle and the lower tower 121 is divided into a plurality of triangular frames 1212 to improve the bearing capacity of the wind power generator tower structure 10, and the upper tower 122 is used to improve the height of the wind power generator tower structure 10, meanwhile, since the lower tower 121 and the upper tower 122 are hollow out, the wind power generator tower structure 10 can reduce the construction cost and the construction period compared with the tower cylinder type tower under the condition of the same stability and the same height, and the wind power generator tower structure 10 of the present utility model has the advantages of high stability and low construction cost.

In one embodiment, the wind turbine tower structure 10 further includes an annular collar 13, the annular collar 13 is provided with a plurality of annular collars 13, the plurality of annular collars 13 are connected to the tower main body 12 from bottom to top, and the annular collar 13 is provided with a plurality of limiting holes 131, and the limiting holes 131 are used for inserting the upright 1211 and the support rods 1221. Specifically, in the present embodiment, the annular hoops 13 include a first annular hoops 13 connected to the lower tower 121 and a second annular hoops 13 connected to the upper tower 122, the first annular hoops 13 are provided in plurality, the first annular hoops 13 are provided with a plurality of limiting holes 131 at intervals in the height direction of the lower tower 121, the first annular hoops 13 are provided with a plurality of limiting holes 131, the number of limiting holes 131 on the first annular hoops 13 is in accordance with the number of the vertical columns 1211 constituting the lower tower 121, the size of the limiting holes 131 on the first annular hoops 13 is adapted to the shaft diameters of the vertical columns 1211, the limiting holes 131 on the first annular hoops 13 are provided for insertion of the vertical columns 1211 on the lower tower 121, correspondingly, the second annular hoops 13 are provided in plurality, the second annular hoops 13 are provided with a plurality of limiting holes 131 at intervals in the height direction of the upper tower 122, the number of limiting holes 131 on the second annular hoops 13 is in accordance with the number of the supporting rods 1221 constituting the upper tower 122, the size of the limiting holes 131 on the second annular hoops 13 is adapted to the shaft diameters of the supporting rods 1221, and the limiting holes 131 on the second annular hoops 13 are inserted into the supporting rods 1221 on the upper annular hoops 13. It will be appreciated that the lower and upper towers 121, 122 can be restrained by the annular collar 13 to avoid separation of the plurality of posts 1211 or the plurality of support rods 1221 by being drawn toward the middle or fanned out.

In one embodiment, a stabilizing plate 14 is provided between two adjacent annular hoops 13, the stabilizing plate 14 being provided with at least two stabilizing plates 14, the at least two stabilizing plates 14 being disposed crosswise. Specifically, in the present embodiment, at least two stabilizer plates 14 can form a plurality of triangles between the adjacent two first annular hoops 13 and the adjacent two columns 1211 after crossing, which improves stability between the adjacent two columns 1211 and the adjacent two annular hoops 13 due to the stability of the triangles, and thus can improve stability of the lower tower 121. Accordingly, at least two stabilizing plates 14 can also form a plurality of triangles between the adjacent two second annular hoops 13 and the adjacent two support rods 1221 after crossing, thereby improving the stability of the upper tower 122. It should be noted that, since the adjacent two annular hoops 13 and the adjacent two vertical posts 1211 or the adjacent two support rods 1221 are trapezoidal, when the disposed stabilizer plate 14 is in an X shape, i.e. formed by two intersecting pieces, at this time, the trapezoid is divided into 4 triangles, and of course, the two stabilizer plates 14 may also intersect to form a V shape, at this time, the trapezoid is divided into 3 triangles, and of course, the number of the stabilizer plates 14 is not limited to two, and when the number of the stabilizer plates 14 is 4, the trapezoid may intersect to form a W shape, at this time, the trapezoid is divided into 5 triangles.

In one embodiment, the lower tower 121 is provided with a weight structure 15, and the lower tower 121 is passed through the weight structure 15 to increase mass. It will be appreciated that by attaching the weight structure 15 to the lower tower 121 to increase the mass of the lower tower 121 as compared to increasing the mass of the columns 1211 to increase the mass of the lower tower 121, inconvenience in installation and transportation due to the increased mass of the columns 1211 can be avoided, and at the same time, the increased mass of the lower tower 121 is fixed after the columns 1211 are increased in mass, without the total number of columns 1211 being changed, which is inconvenient in the adjustment of the center of gravity.

Further, the weight structure 15 includes a reservoir that adds weight to the reservoir by storing seawater. The advantage of using the reservoir is that the mass of the reservoir can be changed by accumulating sea water in the reservoir to adjust the center of gravity, so that the wind turbine tower structure 10 reaches a stable mouth state, and at the same time, when the reservoir is built, the construction cost can be reduced due to the mass of the reservoir and the mass composition of the sea water, and in addition, the wind turbine 20 is built on the sea surface, so that the sea water is easily obtained, and the cost of the sea water is saved.

Further, the water reservoir is installed with a water pump electrically connected to the wind power generator 20, and the water pump pumps seawater by power of the wind power generator 20 to increase the weight of the water reservoir. It will be appreciated that the benefit of using a pump to pump water is that, as the pump is driven by electricity, this enables the electrical energy generated by the wind generator 20 to just meet the energy supply requirements of the pump. The water pump is installed because sunlight on the sea surface is large, after the first reservoir is full of water, the seawater in the reservoir gradually decreases to be no along with evaporation, and the seawater in the reservoir can be replenished by pumping the ocean through the water pump.

In an embodiment, the wind power generator tower structure 10 further comprises an energy storage tank 16, a water pump is installed in the energy storage tank 16, the energy storage tank 16 pumps seawater through the water pump, the energy storage tank 16 is used for discharging the seawater after being filled, and the energy storage tank 16 is provided with a generator, and the generator generates electricity through discharging the seawater. It can be appreciated that, due to the wind period and the no wind period existing on the sea surface, the wind power generator 20 can not generate electricity due to no wind power during the wind period, and the seawater in the energy storage tank 16 is pumped to generate electricity during the no wind period by pumping the seawater to the energy storage tank 16 during the wind period, so that the wind power generator 20 can generate electricity during both the wind period and the no wind period.

Further, the energy storage pool 16 is located on an upper tower 122. It will be appreciated that since the generator generates electricity from the gravitational potential energy of the sea water, i.e. the higher the sea water is, the greater the gravitational potential energy of the sea water is, which results in more electricity being produced and the upper tower 122 is located higher, locating the energy storage pool 16 on the upper tower 122 can increase the electricity production.

Further, the volume of the energy storage reservoir 16 is smaller than the volume of the reservoir. It will be appreciated that reducing the volume of the energy storage pool 16 can increase the stability of the wind turbine tower structure 10 in order to avoid problems with the stability of the wind turbine tower structure 10 due to the mass of the sea water in the energy storage pool 16 and the mass of the energy storage pool 16 itself being greater than the mass of the sea water in the reservoir and the mass of the reservoir itself.
