DETAILED DESCRIPTION

[0022] The technical scheme in the embodiments of the utility model will be apparently and completely described below with the drawings in the embodiments of the utility model, and apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the range of protection of the utility model.

[0023] As shown in Figures 1-5 The utility model relates to ship type wind sail vertical shaft turns double flat shaft wind driven generator unit cluster type frame, including two double limb tower drums 1, double limb tower drum 1 adopts two tower drums of left and right each combination, install elevator in the inside, and the planar figure of such cylinder has greater inertial moment on statics, makes the lateral wind pressure ability of the tower drum that stands up strengthens, thereby makes as the stability of the tower drum of frame column of the double limb tower drum, compared with the stability of single tower drum greatly enhances, and after building, does not tend to lose stability in work.

[0024] The outer wall of the double-limb tower drum 1 is welded with two triangular supporting rods 2, the bottom of the two triangular supporting rods 2 is located on the ground, the stability of the double-limb tower drum 1 is increased, the outer wall of the double-limb tower drum 1 is hinged with two safety doors 3, a plurality of trusses 4 are fixedly connected between the two double-limb tower drums 1, the plurality of trusses 4 are composed of web members, top chords and bottom chords, the top of the plurality of trusses 4 is fixedly connected with an upper edge steel plate 5, and the bottom of the plurality of trusses 4 is fixedly connected with a lower edge steel plate 6.

[0025] The double-limb tower drum 1 is a vertical stress support body, and also supports a dozens of meters span horizontal beam arranged horizontally, the steel structure frame is designed according to the conventional design, the span of the horizontal beam reaches dozens of meters, in order to improve the rigidity, most of the steel box beams are adopted, however, in the frame design, this scheme cannot be adopted, the reason is that the frame with a height of more than 100 meters is erected, the wind pressure when the lateral wind comes is considered first, due to the relatively large plane inertia moment of the double-limb tower drum 1, and the large weight of the bottom inclined steel drum and the force of the triangular support, the lateral wind pressure is large enough, however, if the dozens of meters span single steel box beam, the lateral length and the area of the height are large, the wind pressure generated is also large, the wind pressure generated by the vertical surface of the steel box beam of several layers is very large, if the strong wind attacks, the frame will not be unstable and overturn, but will shake and generate resonance, and the frame will be damaged, and the wind power generation work will be greatly affected under the condition that the normal stable structure support cannot be ensured.

[0026] In order to ensure the overall stability of the frame and not to shake and generate resonance when the strong wind attacks, the dozens of meters span horizontal structure beam adopts the steel truss scheme, since the truss 4 plays the role of the beam, the structure is reasonable and meets the specification requirements, the key point is that the truss 4 is welded by various section steels through calculation, therefore, the truss 4 naturally forms many geometric holes, when the strong wind attacks, the strong wind can directly pass through the geometric holes of the truss 4, and effectively releases the pressure from top to bottom of the truss 4 and the whole frame, and the wind pressure generated by each web member of the truss 4 is much smaller than that generated by the side plate of the steel box beam, and will not affect the truss 4 and the frame.

[0027] The top of each of the plurality of upper edge steel plates 5 is fixedly connected with a damping and noise reduction rubber pad 7, the top of each of the plurality of damping and noise reduction rubber pads 7 is fixedly connected with an outer protective box body 8, the top of each of the plurality of damping and noise reduction rubber pads 7 is fixedly connected with two generator set bodies 9, and the two generator set bodies 9 are located inside the outer protective box body 8. The outer protective box body 8 protects the generator set body 9, and the damping and noise reduction rubber pad 7 plays a role in reducing vibration and noise.

[0028] The top of the upper edge steel plate 5 is provided with a generator mechanism, and the generator mechanism comprises a vertical shaft body 10. The outer end conical gears of the horizontal gear shafts of the two generator set bodies 9 are all in meshing transmission connection with the lower horizontal conical gears of the vertical shaft body 10. The specific transmission connection mode refers to the existing patent with the patent number 2024212590827.

[0029] The outer wall of the vertical shaft body 10 is fixedly connected with a plurality of ship-type wind sail rotating frames 11. The top of each ship-type wind sail rotating frame 11 is fixedly connected with a rotating frame upper chord 12. A plurality of horizontal support rods 13 are fixedly connected between the two double-limb tower drums 1 and the plurality of trusses 4. The top of the upper edge steel plate 5 is fixedly connected with a personnel walking guardrail 14.

[0030] On the basis of the patent with the patent number 2024212590827, the rotating frame lower chord connected ∩-type guide rails and the cantilever support beam are removed. Actually, the ship-type wind sail rotating frame 11 has high rigidity, high processing precision of each rod, and balanced weight, so that the stability of the overall structure of the ship-type wind sail rotating frame 11 is ensured, and the service life of the ship-type wind sail rotating frame 11 is ensured. Therefore, the ship-type wind sail rotating frame 11 will not deform and be unstable in static and dynamic states, so it is not necessary to add a conservative setting such as a cantilever support beam.

[0031] The design is provided with safety doors 3 below the two double-limb tower drums 1 and on each layer, including the topmost layer. The safety doors 3 are convenient for installation and maintenance personnel to ride on the single-person express elevator to work. Personnel walking guardrails 14 are arranged on the left and right sides of the trusses 4 outside the safety doors 3 on each layer, and reach the outer protective box body 8 to protect the safety of the installation and maintenance personnel.
