Description

Technical Field

[0001] This utility model relates to the field of frequency regulation technology for wind power stations, specifically a frequency regulation device for wind power stations. Background Technology

[0002] A wind power station, also known as a wind farm, is a facility that uses wind power to drive wind turbines, converting wind energy into electrical energy. In a wind power station, frequency regulation equipment is a crucial device used to maintain the stability of the power grid frequency. Because wind power generation is intermittent and unpredictable, changes in wind speed cause fluctuations in power output, thus affecting the frequency stability of the power grid. Therefore, frequency regulation equipment ensures that the power grid frequency remains within a stable range by dynamically adjusting the output power of the wind power system or using energy storage technology.

[0003] The patent document with announcement number CN219960125U describes a frequency modulation device for a wind power station. The described scheme uses a baffle to drive a push rod to move together, thereby moving a fixed plate and a positioning plate together. The positioning plate and the limiting groove are separated, completing the disassembly operation, shortening the operation time of the staff, and improving the use effect of the frequency modulation device.

[0004] The aforementioned technology has the problem of not being able to support the electrical cabinet. If the electrical cabinet does not have a reliable support structure, it may tilt or even fall over under the action of external forces (such as wind or earthquakes). The core components inside the electrical cabinet may be damaged due to vibration or impact, and the tilting of the electrical cabinet may cause the wiring to become loose and the cables to break, thereby causing shutdown or power outage.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] In one embodiment, such as Figures 1-5As shown, a frequency modulation device for a wind power station includes: an electrical cabinet 100, a cover plate 200, a mounting box 300, a frequency modulation device 400, and a limiting assembly. The cover plate 200 is disposed on the electrical cabinet 100, the mounting box 300 is disposed inside the electrical cabinet 100, and the frequency modulation device 400 is disposed inside the mounting box 300. The limiting assembly includes two support plates 501, which are respectively disposed at both ends of one side of the electrical cabinet 100. Sliding grooves 502 are provided inside both sides of the electrical cabinet 100, and racks 503 are slidably connected inside the sliding grooves 502. 3. A rotating gear 504 meshes with each other. A first limiting rod 505 is provided on the gear shaft of the rotating gear 504. The end of the first limiting rod 505 away from the rotating gear 504 is slidably connected to the inside of the mounting box 300. A limiting block 506 is provided on one end of the first limiting rod 505. A support block 507 is also rotatably connected to the first limiting rod 505. A first spring 508 is provided between the two ends of the support block 507 near the support plate 501 and the support plate 501. The support plate 501 is also provided with a transverse groove 509 that matches the shape and specifications of the limiting block 506. The rack 5... The top of the 03 is equipped with a support assembly for supporting the rack 503. The electrical cabinet 100 is equipped with a fixing assembly for fixing the cover plate 200. Both ends of the electrical cabinet 100 are equipped with stabilizing assemblies for securing the electrical cabinet 100. When it is necessary to remove the mounting box 300, the first limiting rod 505 can be pulled to move the limiting block 506 and the support block 507, and compress the first spring 508. Then, when the limiting block 506 passes through the transverse groove 509, the first limiting rod 505 is rotated to make the limiting block 506 and the transverse groove 509 form a cross shape, thereby... The first limiting rod 505 is moved away from the mounting box 300, so that the mounting box 300 can be removed. Then, when it is necessary to limit and fix the mounting box 300, the mounting box 300 can be placed inside the electrical cabinet 100, and then the two racks 503 are pushed down, thereby driving the two rotating gears 504, which in turn drives the first limiting rod 505 and the limiting block 506 to rotate. When the limiting block 506 is parallel to the transverse groove 509, the first spring 508 will drive the limiting block 506 and the first limiting rod 505 to approach the mounting box 300, thereby reaching its interior and limiting it.

[0032] In one embodiment, such as Figure 2 and Figure 3As shown, the support assembly includes two connecting rods 601, which are respectively fixedly connected to the tops of two racks 503. Support rods 602 are provided at the tops of the two connecting rods 601. The support rods 602 are slidably connected to the inside of the electrical cabinet 100. Storage holes 603 are provided at both ends of the support rods 602. Limiting posts 604 are slidably connected inside each of the two storage holes 603. A second spring 605 is provided between the limiting posts 604 and the storage holes 603. The electrical cabinet 100 has several limiting holes 606 on both sides inside, which are adapted to the shape and specifications of the limiting pins 604. By pulling the support rod 602, it drives the rack 503 to move. The movement of the support rod 602 will also squeeze the limiting pins 604, which will squeeze the second spring 605. When the limiting pins 604 reach the limiting holes 606, they will be driven into the limiting holes 606 by the action of the second spring 605, thereby limiting and supporting the support rod 602.

[0033] In one embodiment, such as Figure 1 As shown, the fixing component includes two locking blocks 701, which are respectively located on both ends of one side of the cover plate 200. The electrical cabinet 100 is provided with two buckles 702. By bringing the cover plate 200 close to the electrical cabinet 100 and then pulling the buckles 702, the cover plate 200 is fixed to the locking blocks 701 and engaged with them.

[0034] In one embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, the stabilizing component includes a plurality of first support frames 801, which are all disposed at both ends of the electrical cabinet 100. The plurality of first support frames 801 are rotatably connected to rotating columns. The outer surface of the rotating columns is provided with first support columns 802. The outer surface of the first support columns 802 is slidably connected with second support columns 803. The second support columns 803 are provided with adjustment components for adjusting the first support columns 802. The first support columns 802 are supported by the second support columns 803, and then the electrical cabinet 100 is supported by the first support frames 801.

[0035] In one embodiment, such as Figure 1 and Figure 4As shown, the adjusting assembly includes several locking screws 901, all of which are threadedly connected to the inside of the second support column 803. The first support column 802 has several threaded holes. An L-shaped block 902 is provided at the top of the first support column 801. A second support column 903 is provided on the side of the L-shaped block 902 away from the first support column 801. A second limiting rod 904 is slidably connected inside the second support column 903. A turntable 905 is also fixedly connected to the end of the rotating column away from the first support column 801. The turntable 905 has several through holes 906 whose shape and specifications match those of the second limiting rod 904. The second limiting rod 904 passes through the L-shaped block 902, the through holes, and the second limiting rod 904. A support frame 801 is provided, and a tension spring 907 is provided between the second support frame 903 and the second limiting rod 904. When adjustment is required, the second limiting rod 904 can be pulled away from the through hole 906, thereby causing the first support column 802 to rotate. Then, the locking screw 901 is rotated away from the threaded hole, thereby causing the first support column 802 to slide inside the second support column 803. After the adjustment is completed, the locking screw 901 is rotated again to bring it closer to the threaded hole, thereby fixing the first support column 802. Then, the tension on the second limiting rod 904 is released, and under the action of the tension spring 907, it drives the through L-shaped block 902, the through hole and the first support frame 801, thereby limiting the turntable 905.

[0036] In one embodiment, such as Figure 1 As shown, the cover plate 200 is connected to the top of the electrical cabinet 100 by a hinge, and the side of the cover plate 200 near the top of the electrical cabinet 100 is magnetically attracted to the top of the electrical cabinet 100 to prevent the cover plate 200 from falling off when opened.

[0037] In one embodiment, such as Figure 4 and Figure 5 As shown, each of the first limiting rod 505 and the second limiting rod 904 has a pull ring at one end, which facilitates pulling the first limiting rod 505 and the second limiting rod 904.

[0038] In one embodiment, such as Figure 1 As shown, each of the second support columns 803 has a support foot at the end away from the first support column 802 to increase stability.

[0039] The above embodiment discloses a frequency modulation device for a wind power station. The buckle 702 can be pulled away from the locking block 701, allowing the cover plate 200 to open. When the mounting box 300 needs to be removed, the first limiting rod 505 can be pulled, causing the limiting block 506 and support block 507 to move and compress the first spring 508. Then, as the limiting block 506 passes through the transverse groove 509, the first limiting rod 505 is rotated, causing the limiting block 506 and the transverse groove 509 to form a cross shape, thus moving the first limiting rod 505 away from the lock. The mounting box 300 is installed so that it can be removed. When it is necessary to limit and fix the mounting box 300, it can be placed inside the electrical cabinet 100. Then, the support rod 602 is pulled, causing the rack 503 to move, which in turn drives the two rotating gears 504. This, in turn, causes the first limiting rod 505 and the limiting block 506 to rotate. When the limiting block 506 is parallel to the transverse groove 509, the first spring 508 will cause the limiting block 506 and the first limiting rod 505 to move closer to the mounting box 300. The movement of the support rod 602 also presses the limiting pin 604, causing it to press the second spring 605. When the limiting pin 604 reaches the limiting hole 606, it will be driven by the second spring 605 to enter the limiting hole 606, thus limiting and supporting the support rod 602. The second support column 803 can support the first support column 802, and then the electrical cabinet 100 is supported by the first support frame 801. When the support angle needs to be adjusted, the second limiting pin can be pulled. Move the positioning rod 904 away from the through hole 906, thereby rotating the first support column 802. Then, rotate the locking screw 901 away from the threaded hole, allowing the first support column 802 to slide inside the second support column 803. After adjustment, rotate the locking screw 901 again to bring it closer to the threaded hole, thereby fixing the first support column 802. Then, release the tension on the second limiting rod 904, allowing it to move through the L-shaped block 902, the through hole, and the first support frame 801 under the action of the tension spring 907, thereby limiting the turntable 905.

[0040] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
