Description

Technical Field

[0001] The present invention relates to the technical field of electrical engineering, and particularly to a pedestal for a wind turbine generator. Background Art

[0002] A wind turbine generator includes a foundation structure, a tower barrel structure, a unit structure, etc. Since the tower barrel structure is relatively high and the entire tower barrel and unit structure have a large mass, the horizontal and vertical loads borne by the entire wind turbine generator are relatively large, and a relatively stable foundation structure is required. The existing foundation structures are generally reinforced concrete structures, which have good stability and high strength and can effectively provide support for the tower barrel.

[0003] The patent application with the application number CN202110817969.8 discloses a pedestal for a wind turbine generator, which includes a frustum-shaped seat body, a plurality of annular seat bodies with different diameters, a plurality of connecting columns, and an intermediate seat body. The plurality of annular seat bodies are concentrically arranged at the upper end of the frustum-shaped seat body. A plurality of insertion holes are uniformly arranged along the circumferential direction on the annular seat body. The connecting columns can be inserted into the insertion holes, and a plurality of steel bars are embedded in the annular seat body.

[0004] However, this patent also has the following deficiencies. That is, when the wind turbine generator encounters severe weather such as hurricanes, due to the influence of the excessive wind speed on the fan blades of the wind turbine, the loads on the tower barrel and the bottom pedestal at the bottom of the generator exceed the standard. This will cause the tower barrel to have a slight horizontal swing and cause the components inside the generator nacelle to vibrate, and seriously affect the use effect of the wind turbine generator. In view of this situation, a pedestal for a wind turbine generator is specifically proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide a pedestal for a wind turbine generator to solve the problems raised in the above background art.

[0008] According to the above technical solution, the support mechanism includes a base fixedly connected to the bottom of the tower barrel. A fixing ring is slidably connected to the inner wall of the tower barrel. The connecting foot is fixedly connected to the top of the fixing ring. A support rod is fixedly connected to the bottom of the fixing ring. When the fixing ring slides, it will impact the support rod on its surface.

[0009] Stabilizing component, including a connecting cylinder fixedly connected to the surface of the base. A compression film is slidably connected to the top slot of the connecting cylinder. A connecting ring is slidably connected to the inner wall of the connecting cylinder. The end of the support rod away from the fixing ring is fixedly connected to the top of the compression film. A support film is fixedly connected to the bottom of the inner wall of the connecting cylinder. The support film is fixedly connected to the bottom of the connecting ring. A contraction column is slidably connected to the bottom slot of the connecting cylinder. A buffer film is fixedly connected to the inner wall of the contraction column. By making contact with the underground soil through multiple buffer films, the pressure caused by the support rod is released to the outside into the ground.

[0010] According to the above technical solution, the connecting ring is fixedly connected to the surface of the compression film. One end of the compression film is fixedly connected to the top of the contraction column through the inside of the connecting cylinder. When the contraction column leaks out from the inside of the connecting cylinder, it will squeeze the underground soil.

[0011] According to the above technical solution, the support film has the characteristics of telescopic resilience. The buffer film has the function of elastic expansion and contraction. Buffer grooves are formed on the surface of the support film. When the connecting ring slides, it will press the support film.

[0012] According to the above technical solution, the cooling component includes a rotating ring, which is fixedly connected to the surface of the protective plate. The inner wall of the rotating ring is rotatably connected to a connecting arm through a rotating shaft. One end of the connecting arm away from the rotating ring is fixedly connected to a clamping frame. The inner wall of the clamping frame is fixedly connected to a connecting cavity, and a spraying pipe is fixedly connected to the surface of the connecting cavity. A storage tank is fixedly connected to the left side of the connecting arm. The coolant is sprayed outwards through the spraying pipe on the surface of the connecting cavity into the heat dissipation groove.

[0013] According to the above technical solution, a transfer pump is arranged inside the rotating ring, the storage tank is filled with coolant, and a clamping block is installed on the clamping frame. The switch of the transfer pump inside the rotating ring is pushed by air flow.

[0014] According to the above technical solution, the coating film has the function of telescopic folding inside and outside, the sliding arm has the function of elastic telescoping, and absorption grooves are formed on the surface of the friction pipe. The right side of the top cover is covered and supported by the coating film.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By setting the support mechanism in the present invention, when the contraction column leaks out from the inside of the connecting cylinder, it will produce extrusion with the underground soil. At this time, the buffer film inside the contraction column will pop outwards due to its telescopic elasticity and come into contact with the underground. Through the contact of multiple buffer films with the underground soil, the pressure caused by the support rod is released to the outside into the ground. By setting this mechanism, the load caused by strong wind on the tower barrel at the top of the machine base is released through the ground, reducing the swing amplitude of the tower barrel at the top of the machine base.

[0016] 2. By setting the fixing mechanism in the present invention, when the two clamping arms slide, they will come into contact with the top of the top cover. The surface of the top cover is clamped by the insertion between the clamping arms. Since the fan blades of the wind turbine are blown by strong wind, it will cause vibration on the surface of the connected nacelle, which will lead to loosening at the connection between the top cover and the nacelle. By setting this mechanism, the stability between the top cover and the nacelle is improved.

[0017] 3. By setting the protection component in the present invention, due to the telescopic elasticity of the sliding arm itself, it will drive the sliding arm to pop out from the inside of the telescopic arm, which will drive the coating film connected to the telescopic arm to stretch outwards. The right side of the top cover is covered and supported by the coating film. By setting this component, when the connection between the top cover and the nacelle becomes loose, through the supporting effect of the coating film on the right side of the top cover, it is avoided that the top cover detaches from the connection of the nacelle, thus preventing damage to the wind turbine.

[0018] 4. The present invention is provided with a cooling component. The coolant will absorb and evaporate the heat inside the heat dissipation grooves and generate water vapor. By setting this component, when strong wind occurs, it will cause an increase in the internal working load of the generator and a large amount of heat is generated and enters the cabin. It can reduce the heat inside the cabin and avoid the negative impact on the parts around the generator caused by the increase in the temperature inside the cabin. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE INVENTION

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] Examples of the embodiments are shown in the drawings, where like or similar reference numerals designate like or similar elements or elements having like or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0023] In the present invention, unless otherwise clearly defined and limited, terms such as "installed", "connected", "connected to", "fixed", etc. shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] Embodiment 1: Refer to Figures 1 - 5 , the present invention provides a technical solution: a base of a wind turbine 11, including a tower barrel 1, the top of the tower barrel 1 is fixedly connected with a nacelle 2, the left side of the inner wall of the nacelle 2 is rotatably connected with a main shaft 16, the bottom of the inner wall of the nacelle 2 is fixedly connected with a generator 11, the left side of the generator 11 is fixedly connected with a gearbox 12, the inner wall of the gearbox 12 is rotatably connected with one end of the main shaft 16, the top of the nacelle 2 is fixedly connected with a telescopic block 13, the inner wall of the telescopic block 13 is slidably connected with a gasket 14, both sides of the nacelle 2 are fixedly connected with plug-in frames 15, the inner wall of the nacelle 2 is slidably connected with a top cover 3, the left side of the top cover 3 is fixedly connected with a connecting bolt 6, the top of the top cover 3 is provided with a heat dissipation groove 4, the right side of the top cover 3 is fixedly connected with a connecting frame 5, the left side of the nacelle 2 is rotatably connected with a wind turbine blade 10 through the main shaft 16, the bottom of the tower barrel 1 is provided with a support mechanism 7. The top cover 3 of this wind turbine slides through the sliders on both sides of the inner wall of the nacelle 2. When the top cover 3 slides to one side of the inner wall of the nacelle 2, the top cover 3 is connected to the bolt holes on the inner wall of the nacelle 2 through the connecting bolt 6. At the same time, start the internal telescopic device of the telescopic block 13 to drive the gasket 14 to expand from the inside to the outside to the surface of the plug-in frame 15, and the gasket 14 is inserted and fixed with the plug columns at both ends of the plug-in frame 15 through the insertion holes on the surface of the gasket 14, so as to perform secondary sealing on the connection between the top cover 3 and the nacelle 2 to prevent rainwater from seeping into the nacelle 2 during thunderstorms. It also includes: The support mechanism 7 includes a base 703, which is fixedly connected to the bottom of the tower barrel 1. A fixed ring 701 is slidably connected to the inner wall of the tower barrel 1. A connecting foot 801 is fixedly connected to the top of the fixed ring 701. A support rod 702 is fixedly connected to the bottom of the fixed ring 701. When the wind turbine encounters harsh weather such as strong winds, this will impact the tower barrel 1 at the bottom of the generator, causing the pedestal connected to the bottom of the tower barrel 1 to become loose. When the surface of the fan blade 10 of the wind turbine is impacted by strong winds, the load between the tower barrel 1 and the pedestal will exceed the standard, resulting in a slight horizontal swing of the tower barrel 1, which will cause the fixed ring 701 to slide on the surface of the tower barrel 1.

[0025] The stability component 704 includes a connecting cylinder 7041 fixedly connected to the surface of the base 703. A compression film 7042 is slidably connected to the top slot of the connecting cylinder 7041. A connecting ring 7044 is slidably connected to the inner wall of the connecting cylinder 7041. One end of the support rod 702 away from the fixed ring 701 is fixedly connected to the top of the compression film 7042. A support film 7043 is fixedly connected to the bottom of the inner wall of the connecting cylinder 7041. The support film 7043 is fixedly connected to the bottom of the connecting ring 7044. A contraction column 7045 is slidably connected to the bottom slot of the connecting cylinder 7041. A buffer film 7046 is fixedly connected to the inner wall of the contraction column 7045. When the fixed ring 701 slides, it will impact the support rod 702 on its surface, causing one end of the support rod 702 to impact the compression film 7042. The compression film 7042 is made of aging-resistant silicone rubber, with a thickness of 5 mm and an elastic modulus of 10 MPa, and can withstand more than 100,000 compression cycles. This causes the compression film 7042 to contract inward into the interior of the connecting cylinder 7041. When the compression film 7042 expands and contracts inside the connecting cylinder 7041, it will drive the connecting ring 7044 to slide on the surface of the connecting cylinder 7041. When the connecting ring 7044 slides, it will press on the support film 7043, driving the support film 7043 to expand and contract inward. The support film 7043 is made of high-strength polyurethane material, and buffer grooves are provided on the surface to enhance the deformation ability. The inward expansion and contraction of multiple support films 7043 can buffer the pressure caused by one end of the support rod 702.

[0026] The connecting ring 7044 is fixedly connected to the surface of the compression film 7042. One end of the compression film 7042 is fixedly connected to the top of the contraction column 7045 through the interior of the connecting cylinder 7041. When the shaking amplitude of the tower barrel 1 is too high, the pressure on the support rod 702 will be higher, which will cause the compression film 7042 to contract inward more strongly, causing the contraction column 7045 at one end of the compression film 7042 to extend out from the bottom of the connecting cylinder 7041. When the contraction column 7045 leaks out of the connecting cylinder 7041, it will squeeze with the underground soil, and at this time, the buffer film 7046 inside the contraction column 7045 will pop out outward due to its expansion elasticity and come into contact with the ground.

[0027] The support film 7043 has the characteristics of stretching and resilience, and the buffer film 7046 has the function of elastic stretching. Buffer grooves are provided on the surface of the support film 7043. Contact is made with the underground soil through a plurality of buffer films 7046, so as to release the pressure caused by the support rod 702 to the outside into the ground, release the load caused by strong wind on the tower barrel 1 at the top of the machine base through the ground, and reduce the swing amplitude generated by the tower barrel 1 at the top of the machine base.

[0028] Embodiment 2: On the basis of Embodiment 1, continue to refer to Figures 5 - 6 , the present invention provides a technical solution: a fixing mechanism 8, including a telescopic cavity 803 fixedly connected to the bottom of the nacelle 2. A telescopic film 802 is fixedly connected to the bottom of the telescopic cavity 803. A connecting foot 801 is fixedly connected to the bottom of the telescopic film 802. A clamping arm 804 is slidably connected to the inner wall of the telescopic cavity 803 through a slider. A buffer belt 805 is fixedly connected to the inner wall of the clamping arm 804. A transmission rod 806 is fixedly connected to the inner wall of the telescopic cavity 803. A protection component 807 is arranged on the surface of the telescopic cavity 803. When the connecting ring 7044 slides on the surface of the tower barrel 1, it will impact the telescopic film 802, causing the telescopic film 802 to stretch inwards. When the telescopic film 802 contracts inwards, air flows through the guiding channel into the piston chamber at the bottom of the telescopic cavity 803, and the air pressure pushes the piston, driving the clamping arm 804 to extend outwards along the slider track. When the two clamping arms 804 stretch outwards to be inserted together, since soft pads are installed at the bottom of the clamping arms 804, the two clamping arms 804 will come into contact with the top of the top cover 3 during sliding, and the surface of the top cover 3 will be clamped by the insertion between the clamping arms 804. Since the fan blades 10 of the wind turbine are blown by strong wind, it will generate vibration on the surface of the connected nacelle 2. And the buffer belt 805 is inside the clamping arm 804. When the clamping arm 804 receives the vibration from the top cover 3, it will be transmitted to the buffer belt 805, driving the buffer belt 805 to stretch inwards to buffer the vibration, which will cause looseness at the connection between the top cover 3 and the nacelle 2, thereby improving the stability between the top cover 3 and the nacelle 2.

[0029] The protection component 807 includes a protection plate 8071. The protection plate 8071 is fixedly connected to the surface of the telescopic cavity 803. One end of the transmission rod 806 away from the telescopic cavity 803 is fixedly connected to the inner wall of the protection plate 8071. A telescopic arm 8072 is slidably connected to the top slot of the protection plate 8071. A friction tube 8073 is fixedly connected to the surface of the telescopic arm 8072. A sliding arm 8074 is slidably connected to the inner wall of the telescopic arm 8072. One end of the sliding arm 8074 away from the telescopic arm 8072 is fixedly connected to a covering film 8075. A cooling component 9 is arranged on the surface of the protection plate 8071. When the relative displacement between the top cover 3 and the nacelle 2 exceeds 5 mm, the internal pressure sensor in the nacelle 2 triggers the ejection device inside the protection plate 8071, driving the telescopic arm 8072 to extend to the extreme position within 0.5 seconds. Thereby driving the telescopic arm 8072 to telescopically move upwards and extend out from the top slot of the protection plate 8071. At this time, the friction tube 8073 on the surface of the telescopic arm 8072 will have a sliding contact with the right side of the top cover 3. At the same time, when the telescopic arm 8072 extends out from the inside of the protection plate 8071, due to the telescopic elasticity of the sliding arm 8074 itself, this will drive the sliding arm 8074 to pop out from the inside of the telescopic arm 8072, which will drive the covering film 8075 connected to the telescopic arm 8072 to stretch outwards.

[0030] The covering film 8075 has the function of telescopic folding inside and outside. The sliding arm 8074 has the function of elastic telescoping. Absorption grooves are provided on the surface of the friction tube 8073. The right side of the top cover 3 is covered and supported by the covering film 8075. The covering film 8075 is made of 3-mm thick elastic nylon and can provide a support force of 100 N. When the connection between the top cover 3 and the nacelle 2 becomes loose, through the support effect generated by the covering film 8075 on the right side of the top cover 3, it is avoided that the top cover 3 detaches from the connection of the nacelle 2, thus causing damage to the wind turbine.

[0031] Embodiment 3: On the basis of Embodiment 2, continue to refer to Figures 7 - 8, the present invention provides a technical solution: The cooling component 9 includes a rotating ring 901, which is fixedly connected to the surface of the protective plate 8071. The inner wall of the rotating ring 901 is rotatably connected to a connecting arm 902 through a rotating shaft. One end of the connecting arm 902 away from the rotating ring 901 is fixedly connected to a clamping frame 906. The inner wall of the clamping frame 906 is fixedly connected to a connecting cavity 904. The surface of the connecting cavity 904 is fixedly connected to a spraying pipe 905. The left side of the connecting arm 902 is fixedly connected to a storage tank 903. When the airflow transmitted by the transmission rod 806 enters the rotating ring 901 through the cavity inside the protective plate 8071, the transmission pump switch inside the rotating ring 901 is pushed by the airflow, causing the transmission pump to start and suck the coolant inside the storage tank 903 into the connecting cavity 904. The coolant is sprayed outwards through the spraying pipe 905 on the surface of the connecting cavity 904 into the heat dissipation groove 4. Since the position of the heat dissipation groove 4 is set at the top of the generator 11, when strong wind pushes the fan blades 10, the rotation speed of the gearbox 12 will increase, which will cause the working load inside the generator 11 to increase, and a large amount of heat will be generated inside the housing of the generator 11 and enter the top heat dissipation groove 4.

[0032] A controller is provided inside the rotating ring 901. The storage tank 903 is filled with coolant. A clamping block is installed on the clamping frame 906, and the heat dissipation groove 4 is filled with coolant. The coolant will absorb and evaporate the heat inside the heat dissipation groove 4 and generate water vapor. After the spraying pipe 905 sprays the coolant onto the heat dissipation groove 4, the water vapor that has absorbed heat and evaporated returns to the storage tank 903 through the recovery pipe and is recycled after being condensed by the heat exchanger. The measured data shows that this system can reduce the temperature inside the engine room by 15 - 20 °C. When encountering strong wind, it will cause the working load inside the generator to increase and a large amount of heat to enter the engine room 2. It can reduce the heat inside the engine room 2 and avoid the negative impact on the parts around the generator 11 caused by the increase in the temperature inside the engine room 2. A control machine is provided at the connection between the protective plate 8071 and the rotating ring 901. When it is necessary to remove the top cover 3 from the surface of the engine room 2, the rotating ring 901 is driven to rotate by remotely controlling the control machine, so that the connecting arm 902 rotates outwards, which will drive the clamping block on the surface of the clamping frame 906 to disengage from the inside of the connecting frame 5, facilitating the staff to remove the top cover 3.
