Description

Technical Field

[0001] This utility model relates to the field of wind power generation devices, and in particular to a water-floating rail-mounted steel wheel wind turbine generator. Background Technology

[0002] Currently, wind power generation equipment is broadly divided into two types: horizontal axis wind power generation equipment and vertical axis wind power generation equipment. Horizontal axis wind power generation equipment has been developed earlier and is relatively mature. Most high-power power plants choose this type of equipment. However, the important equipment is installed too high, making maintenance inconvenient. The center of gravity is too high, affecting the stability of the equipment and its ability to resist wind disasters. The yaw system of the equipment and the strength requirements of the tower increase the cost of the equipment. Therefore, vertical axis wind power generation equipment has become the focus of attention and research. Existing vertical axis wind power generation technology has low wind power utilization, difficulty in starting, easy stall, and low output power.

[0003] For example, the invention disclosed in publication number CN111622902A discloses a new type of vertical axis wind power generation equipment overall construction method: it consists of the following main parts: a hemispherical machine room, with a main shaft bearing mounting hole reserved at the top; a middle-level installation platform with a main shaft auxiliary bearing mounting hole in the center of the platform; a generator installation platform on the ground; power generation equipment: a low-speed vertical axis generator installed on the ground platform in the machine room, with the generator input shaft connected to the lower end of the main shaft by a coupling; a multi-functional main shaft: the main shaft is vertically installed through the bearing mounting holes at the top of the machine room and the auxiliary bearing mounting holes on the middle platform, supported by bearings; a multi-functional column: vertically installed at the upper end of the main shaft, connected by a flange, with a horizontally penetrating blade shaft hole reserved in the upper section of the column; a blade shaft: uniformly horizontally installed on the column, with two bearings supporting the blade shaft on each side of the column; two flat movable blades are fixed at both ends of the same blade shaft, with an end-view angle of 90 degrees, and all blades are installed in the same way.

[0004] However, the main shaft of the existing vertical axis wind turbines is rotatably connected by bearings and equipped with a support structure. For larger wind turbines, to ensure the stability of the main shaft support and rotation, the structure becomes more complex and the cost is higher, which is not conducive to the promotion of wind turbines. The power generation components of the wind turbine are connected to the main shaft, the transmission structure is relatively complex, and the wind-catching ability of the vertically set blades is relatively weak. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology, such as the complex main shaft support structure of the wind turbine and the transmission structure between the main shaft and the generator, and to provide a water-floating track steel wheel wind turbine generator that is stable in operation and has high power generation efficiency.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A water-floating track steel wheel wind turbine generator includes a wind turbine base, a wind turbine main shaft and wind turbine blades, and the generator also includes a generator set, an auxiliary generator set, a transmission rail and a motor support platform;

[0008] The wind turbine base is equipped with a wind turbine water tank. The main shaft of the wind turbine is rotatably mounted on the wind turbine base and suspended in the wind turbine water tank. The motor support platform is installed on the periphery of the wind turbine base and located directly below the wind turbine blades. The generator set and the auxiliary generator set are both fixed on the motor support platform. The transmission rail is fixed to the lower end of the wind turbine blades and the transmission rail drives and connects the generator set and the auxiliary generator set respectively.

[0009] Preferably, the rotating shafts of the generator set and the auxiliary generator set are respectively equipped with steel wheels, and the steel wheels are in transmission cooperation with the transmission rail.

[0010] Preferably, the motor support platform is provided with multiple spring shock absorbers, and the generator set and auxiliary generator set are respectively installed on each spring shock absorber.

[0011] Preferably, the wind turbine blade includes a blade top cover, a blade, and a bottom fixing frame;

[0012] The blade top cover is fixed to the upper end of the fan main shaft, the bottom end fixing bracket is fixed to the fan main shaft, one end of the blade is fixed to the blade top cover, and the other end is fixed to the bottom end fixing bracket.

[0013] Preferably, the blade has an arc-shaped structure, and an air inlet slot and an air outlet slot are pressed on both sides of the blade, with the air inlet slot of the blade inclined to the side away from the center of the fan blade.

[0014] Preferably, the wind turbine blades further include a wire rope stay cable, one end of which is fixed to the main shaft of the wind turbine, and the other end is connected to the bottom fixing frame.

[0015] Preferably, the bottom fixing frame includes multiple coaxially arranged circular ring structures, with support rods arranged between adjacent circular ring structures, and the support rods are distributed radially.

[0016] Preferably, the fan main shaft is a stepped shaft, a first bearing is installed at the upper end of the fan main shaft, and a bearing seat is provided at the upper end of the fan base, with the first bearing installed in the bearing seat.

[0017] Preferably, the lower end of the fan main shaft is provided with a fixed bearing and a square steel. The outer ring of the fixed bearing is fixed to the bottom end of the fan main shaft, one end of the square steel is fixed in the inner ring of the fixed bearing, and the other end is fixed to the bottom of the fan water tank.

[0018] Preferably, there are multiple generator sets and auxiliary generator sets, which are distributed alternately on the motor support platform.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] (1) In this scheme, the main shaft of the wind turbine is rotatably installed in the wind turbine base, and the wind turbine water pool in the graded base is used to suspend the main shaft of the wind turbine, thereby completing the fixation and support of the main shaft of the wind turbine. During the rotation of the wind turbine blades, the generator set and auxiliary generator set around the wind turbine base are driven to rotate through the transmission rail installed at the lower end, thereby completing the power generation.

[0021] The transmission rails at the lower end of the wind turbine blades directly drive the generator sets and auxiliary generator sets located around the wind turbine base, thus generating electricity. This simplifies the complex transmission structure connected to the wind turbine main shaft, reduces costs, and provides a larger drive path for the peripheral generator sets, effectively improving power generation efficiency. Suspending the wind turbine main shaft using a water tank effectively reduces friction, further improving power generation efficiency while extending the shaft's lifespan.

[0022] (2) This scheme takes into account that the wind turbine blades will fluctuate in the vertical direction during the rotation process; by installing spring shock absorbers at the lower end of the generator set and the auxiliary generator set, reliable contact between the rail and the steel wheel of the generator set and the auxiliary generator set is ensured, and the generator set is protected to ensure the reliability and stability of the transmission structure.

[0031] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0032] Example 1

[0033] like Figure 1 and Figure 2As shown, this embodiment provides a water-floating rail steel wheel wind turbine generator, including a wind turbine base 1, a wind turbine main shaft 2 and wind turbine blades 3. The generator also includes a generator set 4, an auxiliary generator set 5, a transmission rail 7 and a motor support platform 6.

[0034] The fan base 1 is equipped with a fan water tank 101. The fan main shaft 2 is rotatably mounted on the fan base 1 and suspended in the fan water tank 101. The motor support platform 6 is installed on the periphery of the fan base 1 and is located directly below the fan blades 3. The generator set 4 and the auxiliary generator set 5 are both fixed on the motor support platform 6. The transmission rail 7 is fixed at the lower end of the fan blades 3 and is used to drive and connect the generator set 4 and the auxiliary generator set 5 respectively.

[0035] Working principle: The main shaft 2 of the wind turbine is rotatably installed in the wind turbine base 1, and the main shaft 2 of the wind turbine is suspended by the wind turbine water tank 101 in the graded base 1, thus completing the fixation and support of the main shaft 2 of the wind turbine. During the rotation of the wind turbine blades 3, the generator set 4 and auxiliary generator set 5 around the wind turbine base 1 are driven to rotate through the transmission rail 7 installed at the lower end, thus completing the power generation.

[0036] The transmission rail 7 located at the lower end of the wind turbine blades 3 directly drives the generator set 4 and auxiliary generator set 5 located around the wind turbine base 1 to rotate, thus generating electricity. This simplifies the complex transmission structure connected to the wind turbine main shaft, reduces costs, and the peripheral generator set has a larger drive path, effectively improving power generation efficiency. Suspending the wind turbine main shaft 2 using the wind turbine water tank 101 effectively reduces friction on the main shaft, further improving power generation efficiency and extending the service life of the main shaft 2.

[0037] In a preferred embodiment, steel wheels are respectively provided on the rotating shafts of generator set 4 and auxiliary generator set 5, and the steel wheels are in transmission cooperation with the transmission rail.

[0038] Furthermore, the motor support platform 6 is equipped with multiple spring dampers, and the generator set 4 and the auxiliary generator set 5 are respectively installed on each spring damper.

[0039] Considering that the wind turbine blades will fluctuate in the vertical direction during rotation, spring shock absorbers are installed at the lower end of generator set 4 and auxiliary generator set 5 to ensure reliable contact between the rail and the steel wheels of generator set 4 and auxiliary generator set 5, and to protect the generator set, thus ensuring the reliability and stability of the transmission structure.

[0040] In a preferred embodiment, the wind turbine blade 3 includes a blade top cover 31, a blade 32, and a bottom fixing frame 33;

[0041] The blade top cover 31 is fixed to the upper end of the fan main shaft 2, the bottom fixing bracket 33 is fixed to the fan main shaft 2, one end of the blade 32 is fixed to the blade top cover 31, and the other end is fixed to the bottom fixing bracket 33.

[0042] Furthermore, the blade 32 has an arc-shaped structure, and air inlet slots and air outlet slots are pressed on both sides of the blade 32. The air inlet slot of the blade 32 is inclined to the side away from the center of the fan blade.

[0043] By fixing the two ends of the blade 32 to the blade top cover 31 and the bottom fixing bracket 33 respectively, and distributing the blade 32 around the top cover 31 of the wind turbine, with the blade 32 tilted so that the air inlet on one side faces outward and the air outlet on the other side faces inward, the sweeping area of ​​the wind turbine blade can be effectively increased, resulting in stronger wind capture capability, enabling the wind turbine generator set with greater power and reducing power generation costs.

[0044] Furthermore, the wind turbine blade 3 also includes a wire rope stay cable 34, one end of which is fixed to the wind turbine main shaft 2, and the other end is connected to the bottom fixing frame 33.

[0045] The bottom fixing frame 33 includes multiple coaxially arranged ring structures 35, and support rods 36 are arranged between adjacent ring structures 35, with the support rods 36 distributed radially.

[0046] The bottom fixing frame 33 adopts a coaxially distributed ring structure. Each ring structure is fixed to the main shaft 2 of the wind turbine by multiple steel wire ropes 34. Support rods are set between two adjacent ring structures. The number of support frames between the ring structures increases radially from the inside to the outside. This can ensure structural stability, reduce unnecessary waste, and improve the support capacity of the bottom fixing frame 33 and the stability of the wind turbine blades.

[0047] Specifically, the main shaft 2 of the fan is a stepped shaft, and a first bearing is installed at the upper end of the main shaft 2. A bearing seat is provided at the upper end of the fan base 1, and the first bearing is installed in the bearing seat.

[0048] The lower end of the fan main shaft 2 is provided with a fixed bearing and a square steel. The outer ring of the fixed bearing is fixed to the bottom end of the fan main shaft 2, one end of the square steel is fixed in the inner ring of the fixed bearing, and the other end is fixed to the bottom of the fan water tank 101.

[0049] There are multiple generator sets 4 and auxiliary generator sets 5, which are distributed alternately on the motor support platform 6.

[0050] An auxiliary generator set 5 is distributed between the two generator sets 4. The auxiliary generator set 5 is an integrated generator and motor unit that can drive the transmission rail while also braking the transmission rail, ensuring the rotational speed of the wind turbine blades and the power generation efficiency of the generator set 4, and maintaining the stability of the wind turbine.

[0051] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
