Description

Technical Field

[0001] This invention relates to the field of wind power generation technology, specifically to a low-altitude wind power generation device. Background Technology

[0002] Low-altitude wind power generation equipment refers to small and medium-sized wind power generation devices developed for wind energy resources at low altitudes (usually referring to the range from the ground surface to tens of meters in height). They are mainly used for distributed energy supply, off-grid power supply, or grid supplementation. Low-altitude wind power generation equipment, such as low-altitude wind turbines, are often used in remote areas such as mountains and islands. Due to the higher wind speeds in these areas, and the fact that the center of gravity of low-altitude wind turbines is lower than that of high-altitude wind turbines, their wind resistance in island areas is better than that of high-altitude wind turbines.

[0003] Although low-altitude wind turbines are more wind-resistant than high-altitude wind turbines, when used around islands, the sea breeze is significantly affected by the environment. In extreme wind and rain weather, the wind force is much greater than in other areas. Therefore, the stability of low-altitude wind turbines needs to be further improved. Summary of the Invention

A locking frame is also fixed to the side of the top of the locking frame near the semi-circular groove. The buckle frame and the support ring are respectively attached to the two ends of the cabin.

[0008] The top of the support frame is provided with a connecting component for connecting the cabin and the support frame.

[0009] Optionally, the peak tower has an entrance / exit on the side near the sleeve frame, and the entrance / exit is located above the limiting ring frame. The interior of the peak tower has a partition, and the top of the partition has a yaw gear.

[0010] Optionally, the cabin has a heat dissipation louver on the side near the locking frame, and a yaw motor is fixed at the bottom of the cabin, with the gear of the yaw motor meshing with the yaw gear.

[0011] Optionally, the connecting assembly includes a connecting frame, which is fixed to the top of the support sleeve. A rubber ring is fixed to the top of the connecting frame, and the rubber ring abuts against the bottom of the cabin. An air extraction chamber is provided in the middle of the connecting frame and communicates with the rubber ring. An air pump is fixed to the top of the support sleeve inside the connecting frame, and one end of the air pump outlet pipe is located inside the air extraction chamber.

[0012] Optionally, a sealing plate is fixed to one end of the two connecting frames away from the top of the tower, and a magnetic plate is embedded inside one of the sealing plates. A sealing door is hinged to one end of the connecting frame away from the top of the tower, and the sealing door is attracted to the magnetic plate.

[0013] Optionally, the sleeve has a built-in groove in the middle, and a second cylinder is fixed inside the built-in groove. The output shaft of the second cylinder passes through the top of the support sleeve, and a linkage plate is fixed to the top of the output shaft of the second cylinder. A pressure rod is fixed to the bottom of the linkage plate at the end away from the second cylinder. The pressure rod passes through the top of the support sleeve, and the bottom of the pressure rod abuts against the top of the limiting ring frame.

[0014] Optionally, a guardrail is fixed to the top of the support frame, and a rope hole is provided on the top surface of the guardrail. An adjustable protective frame is slidably connected to both ends of the guardrail. The adjustable protective frame is fixed to the linkage plate. A protective rope is fixed to the top of the adjustable protective frame. The protective rope passes through the rope hole and the top of the protective rope is fixed to the bottom of the cabin.

[0015] Optionally, an inner groove is formed on the surface of the support ring groove, and a roller assembly is rotatably connected inside the inner groove. A first cylinder is fixed inside one end of the support ring, and a pressure ring is fixed to the output shaft of the first cylinder.

A curved air duct is provided inside the semi-circular groove below the ventilation cavity, and the curved air duct is connected to the ventilation cavity.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This low-altitude wind power generation equipment, through the reinforcement of components, increases the stability of the nacelle at the top of the peak tower. This allows the nacelle to deflect at the top of the peak tower while being limited by the peak tower, thus distributing the wind force received by the nacelle to the peak tower, thereby improving the overall wind resistance and stability of the nacelle.

[0019] 2. When encountering strong winds at sea, this low-altitude wind power generation equipment can return via the second cylinder. The second cylinder then drives the linkage plate and adjustable protective frame to return. During the return process, the linkage plate drives the pressure rod to contact the limit ring frame, increasing the friction between the support sleeve and the limit ring frame, which locks the limit ring frame and the support sleeve, reducing the risk of deflection of the support sleeve and nacelle. At the same time, after the adjustable protective frame tauts the protective rope, it can pull the nacelle, further enhancing the wind resistance and stability of the nacelle.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figure 1-10 A low-altitude wind power generation device includes a multi-stage tower 1, a peak tower 11 fixed to the top of the multi-stage tower 1, a nacelle 12 fixed to the top of the peak tower 11, a hub 13 rotatably connected to one end of the nacelle 12, a limiting ring frame 2 fixed to the outside of the peak tower 11, and a reinforcing component for strengthening the center of gravity of the nacelle 12 on the surface of the limiting ring frame 2.

[0033] The reinforcement assembly includes two support sleeves 3. Locking bolts 301 are fixed to the surfaces at both ends of the support sleeves 3. A semi-circular groove 31 is opened inside one side of the support sleeve 3, and the semi-circular groove 31 is sleeved on the surfaces on both sides of the limiting ring frame 2. A sleeve 32 is slidably connected to the surface of the support sleeve 3 near the semi-circular groove 31. A fixing plate 33 is fixed to the side of the sleeve 32 near the semi-circular groove 31. A support rod 34 is fixed to the top of the fixing plate 33, and a support ring 35 is fixed to the top of the support rod 34.

[0034] A locking frame 36 is slidably connected to the end of the support frame 3 away from the frame 32. A buckle frame 37 is fixed to the top of the locking frame 36. A locking frame 38 is fixed to the side of the top of the locking frame 38 near the semi-circular groove 31. The buckle frame 37 and the support ring 35 are respectively attached to the two ends of the cabin 12. The top of the support frame 3 is provided with a connecting component for connecting the cabin 12 and the support frame 3. An entrance 111 is opened on the side of the peak tower 11 near the frame 32, and the entrance 111 is located above the limiting ring frame 2. A partition is provided inside the peak tower 11, and a yaw gear 112 is fixed to the top of the partition.

[0035] A heat dissipation louver 121 is provided on the side of the cabin 12 near the locking frame 36. A yaw motor 122 is fixed at the bottom of the cabin 12, and the gear of the yaw motor 122 meshes with the yaw gear 112. The connecting component includes a connecting frame 4, which is fixed on the top of the support frame 3. A rubber ring 41 is fixed on the top of the connecting frame 4, and the rubber ring 41 abuts against the bottom of the cabin 12. An air extraction chamber 42 is provided in the middle of the connecting frame 4, and the air extraction chamber 42 communicates with the rubber ring 41. An air pump 43 is fixed on the top of the support frame 3 inside the connecting frame 4, and one end of the air outlet pipe of the air pump 43 is located inside the air extraction chamber 42.

[0036] In the specific operation process, firstly, the two support sleeves 3 are sleeved on the outside of the two sides of the limiting ring frame 2 by the hoisting equipment, so that the two support sleeves 3 drive the two connecting frames 4 to assemble into a cylinder. Then, the sleeve 32 is sleeved on one end of the two support sleeves 3, so that the sleeve 32 drives the fixing plate 33 to be snapped on the outside of the locking bolt 301, and the fixing plate 33 is locked on the outside of the support sleeves 3 by the locking bolt 301, thereby locking and limiting one end of the two support sleeves 3.

[0037] Then, the multi-stage tower 1 is hoisted and assembled using hoisting equipment. Next, the peak tower 11 is hoisted and clamped to the top of the multi-stage tower 1. Then, the nacelle 12 is hoisted and clamped to the top of the peak tower 11. Then, the hub 13 is hoisted and clamped to the inside of one end of the nacelle 12. Then, the locking frame 36 is hoisted and clamped to the inside of the two support sleeves 3 at the end away from the sleeve 32, so that the locking frame 36 drives the locking frame 38 to clamp to the outside of the locking bolt 301. At the same time, the position of the locking frame 36 is adjusted by sliding the hoisting equipment, so that the locking frame 36 drives the buckle frame 37 to fit against the end of the nacelle 12 away from the hub 13. Then, the locking frame 38 is locked by the locking bolt 301, so that the locking frame 36 locks and limits the end of the support sleeve 3 away from the sleeve 32.

[0038] While the locking frame 36 locks and limits the support sleeve 3, the buckle frame 37 completes the buckling and limiting of the nacelle 12, thereby making the connection between the nacelle 12 and the peak tower 11 more stable. When facing strong winds at sea, the buckle frame 37 improves the wind resistance and stability of the nacelle 12 and reduces the probability of the nacelle 12 being overturned.

[0039] Meanwhile, as the support rings 35 and the buckle brackets 37 are respectively attached to both ends of the nacelle 12, the nacelle 12 is clamped by the support rings 35 and the buckle brackets 37, which further improves the wind resistance and stability of the nacelle 12.

[0040] Furthermore, when the cabin 12 is hoisted and clamped, the bottom of the cabin 12 is brought into contact with the top of the rubber ring 41. Then, the air pump 43 evacuates the air from the air extraction chamber 42 and the rubber ring 41, causing the rubber ring 41 to adhere to the cabin 12, which further improves the stability of the cabin 12 after hoisting and assembly.

[0041] Meanwhile, the connecting frame 4 is fixed to the top of the support sleeve 3. When the bottom of the cabin 12 is attracted to the rubber ring 41, the cabin 12 is indirectly fixed to the connecting frame 4 and the support sleeve 3. This ensures that when the yaw motor 122 and the yaw gear 112 control the cabin 12 to yaw, the cabin 12 drives the support sleeve 3 and rotates synchronously around the limiting ring frame 2. This causes the sleeve 32 to drive the support rod 34 and the support ring 35 to rotate synchronously, and the locking frame 36 to drive the buckle frame 37 to rotate synchronously. This ensures that the clamping and limiting of the cabin 12 is maintained during the rotation of the cabin 12, thereby improving the stability of the cabin 12 during yaw.

[0042] It should be noted that the limiting ring frame 2 is welded and fixed to the peak tower 11, so that the peak tower 11 and the limiting ring frame 2 are integrated as a whole. The support sleeve 3 is sleeved on the outside of the limiting ring frame 2. Therefore, the support sleeve 3 can rotate around the limiting ring frame 2. When facing strong winds at sea, the peak tower 11 and the limiting ring frame 2 limit the support sleeve 3, and the support sleeve 3 limits the connecting frame 4 and the nacelle 12. In turn, the peak tower 11 can limit the nacelle 12, which further improves the stability of the nacelle 12.

[0043] The surfaces of the fixing plate 33 and the locking frame 38 are provided with slots, so that the fixing plate 33 and the locking frame 38 can be slidably adjusted outside the locking bolt 301 to adjust the engagement distance of the sleeve 32 and the locking frame 36 at both ends of the support sleeve 3, thereby allowing the support ring 35 and the buckle frame 37 to fit against both ends of the cabin 12 respectively.

[0044] Inside the engine compartment 12, there are gearboxes, brake pads, generators, etc. A cooling fan can also be installed inside the engine compartment 12, and hot air is exhausted to the outside through the cooling louvers 121, thereby improving the stability of the internal operating temperature of the engine compartment 12. Similarly, fan blades are provided on the outside of the wheel hub 13. The above are the equipment that should be installed or can be installed inside the engine compartment 12 and wheel hub 13 in the prior art. All the equipment in this invention is controlled by a controller, and will not be described in detail in this application.

[0045] Example 2: Two connecting frames 4 are fixed with sealing plates 44 at the ends away from the top tower 11. One of the sealing plates 44 is embedded with a magnetic plate 45. One of the connecting frames 4 is hinged with a sealing door 46 at the end away from the top tower 11. The sealing door 46 is attracted to the magnetic plate 45. The middle position of the sleeve 32 is provided with an internal groove 5. The internal groove 5 is fixed with a second cylinder 51. The output shaft of the second cylinder 51 passes through the top of the supporting sleeve 3. The top of the output shaft of the second cylinder 51 is fixed with a linkage plate 52. The bottom of the linkage plate 52 away from the second cylinder 51 is fixed with a pressure rod 53. The pressure rod 53 passes through the top of the supporting sleeve 3, and the bottom of the pressure rod 53 abuts against the top of the limiting ring frame 2.

[0046] A guardrail 6 is fixed to the top of the support frame 3. A rope hole 61 is opened on the surface of the top of the guardrail 6. An adjustable protective frame 62 is slidably connected to both ends of the guardrail 6. The adjustable protective frame 62 is fixed to the linkage plate 52. A protective rope 63 is fixed to the top of the adjustable protective frame 62. The protective rope 63 passes through the rope hole 61. The top of the protective rope 63 is fixed to the bottom of the cabin 12.

[0047] Specifically, based on Embodiment 1, during subsequent maintenance of this device, maintenance personnel can enter the top of the support frame 3 through entrance 111, between the connecting frame 4 and the peak tower 11, and then walk around to the sealing door 46. After opening the sealing door 46, they can access the top of the support frame 3 and perform maintenance on the frame 32 and locking frame 36. During maintenance, the protective structure formed by the guardrail 6, adjustable protective frame 62 and protective rope 63 protects both sides of the support frame 3, thereby ensuring the safety of maintenance personnel walking on the top of the support frame 3.

[0048] When facing extreme wind and rain, the nacelle 12 needs to be yawed. After the strong wind has reduced the impact on the invention to a minimum, the invention is shut down. This avoids the strong wind blowing the nacelle 12 and hub 13 to shake and vibrate, thereby reducing the damage to the invention from the strong wind.

[0049] Furthermore, after the invention stops, the second cylinder 51 can be started by the controller, causing the second cylinder 51 to drive the linkage plate 52 to return, causing the linkage plate 52 to move towards the limiting ring frame 2, causing the linkage plate 52 to drive the pressure rod 53 to move towards the limiting ring frame 2, until the bottom of the pressure rod 53 abuts against the top of the limiting ring frame 2. Through the continuous return of the second cylinder 51, the pressure of the pressure rod 53 in contact with the limiting ring frame 2 continues to increase, thereby increasing the friction between the pressure rod 53 and the limiting ring frame 2, and thus increasing the friction and resistance between the support sleeve 3 and the limiting ring frame 2. In this way, the pressure rod 53 achieves the purpose of locking the limiting ring frame 2 and the support sleeve 3.

[0050] Due to the locking of the limiting ring 2 and the support sleeve 3, the limiting of the cabin 12 is achieved through the support sleeve 3, which reduces the deflection and vibration of the cabin 12 when it encounters strong winds after it stops, thereby improving the stability of the cabin 12.

[0051] Furthermore, during the return stroke of the second cylinder 51, the linkage plate 52 causes the adjustable protective frame 62 to move synchronously toward the limiting ring frame 2, which in turn causes one end of the protective rope 63 to move toward the limiting ring frame 2. Thus, the adjustable protective frame 62 straightens the protective rope 63, keeping it taut. The taut protective rope 63 then acts as a traction device for the cabin 12, further increasing the wind resistance and stability of the cabin 12.

[0052] Similarly, the taut protective rope 63 can turbulentize the airflow below the cabin 12, reducing the turbulent wake formed by strong winds at sea below the cabin 12, thereby improving the wind resistance of the cabin 12 and preventing the cabin 12 from being overturned. When the taut protective rope 63 pulls the cabin 12, it can further increase the pressure of the cabin 12 on the rubber ring 41, thereby strengthening the adhesion of the rubber ring 41 to the cabin 12 and further increasing the stability of the cabin 12.

[0053] It should be noted that the protective rope 63 is made of steel cable. The two ends of the protective rope 63 are fixed to the bottom of the cabin 12 and the top of the adjustable protective frame 62 respectively through universal rotating hooks. The diameter of the rope hole 61 is larger than that of the protective rope 63. When the present invention is used in a state of low wind and without stopping the machine, the second cylinder 51 can be controlled to lift up, so that the second cylinder 51 drives the linkage plate 52 and the adjustable protective frame 62 to lift up, so that the protective rope 63 is in a slack state. The slack state of the protective rope 63 not only plays a role in turbulence, but also reduces the fatigue of the protective rope 63 and improves the service life of the protective rope 63. At the same time, the slack state of the protective rope 63 can absorb the instantaneous load of strong wind, further improving the stability of the cabin 12.

[0054] Meanwhile, the protective rope 63, which is in a slack state, can be blown by the wind and sway, preventing the protective rope 63 from freezing when the temperature is low. The initial position of the pressure bar 53 is located inside the top of the support sleeve 3 and does not contact the limiting ring 2.

[0055] Example 3: An inner groove 351 is formed on the surface of the groove of the support ring 35. A roller group 352 is rotatably connected inside the inner groove 351. A first cylinder 353 is fixed inside one end of the support ring 35. A pressure ring 354 is fixed to the output shaft of the first cylinder 353.

[0056] The top of the buckle frame 37 is inclined, and a ventilation cavity 371 is provided inside the buckle frame 37. The ventilation cavity 371 is connected to the interior of the cabin 12 through the heat dissipation louvers 121. A curved air duct 372 is provided inside the semi-circular groove 31 below the ventilation cavity 371. The curved air duct 372 is connected to the ventilation cavity 371.

[0057] Specifically, based on Embodiments 1 and 2, when the present invention needs to be stopped due to strong winds at sea, the controller can control the first cylinder 353 to return, so that the first cylinder 353 drives the pressure ring 354 to move toward the support ring 35. During the movement, the support ring 35 and the pressure ring 354 cover the rotation stroke of the hub 13 and increase the friction of the hub 13's rotation, thereby reducing the probability of the hub 13 deflecting due to wind force when there are strong winds at sea, and thus improving the stability of the hub 13.

[0058] Furthermore, since the present invention is applied to areas near islands or seas, and the salt spray content is high near islands or seas, the support ring 35 and the pressure ring 354 close the rotating shaft to form a clamping state, while shielding the engine compartment 12, reducing the risk of salt spray entering the engine compartment 12 through the area near the wheel hub 13.

[0059] The connection between the nacelle 12 and the peak tower 11 is protected by the protective ring formed by the connecting frame 4, and the sealing effect of the rubber ring 41 enhances the protection against salt spray. At the same time, the heat dissipation louvers 121 are blocked by the buckle frame 37. While ensuring that the heat inside the nacelle 12 is exhausted to the outside through the ventilation cavity 371 and the curved air duct 372, the curved air duct 372 enhances the filtration of salt spray and reduces the probability of salt spray entering the interior of the nacelle 12 from the heat dissipation louvers 121.

[0060] This allows the support ring 35, pressure ring 354, and buckle bracket 37 to not only support the engine compartment 12, but also prevent salt spray from entering the engine compartment 12 after shutdown, reducing the impact of salt spray on the equipment inside the engine compartment 12. Later, the rubber ring 41 can be replaced as a replaceable part, and can be replaced under long-term corrosion.

[0061] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
