Description

Technical Field

[0001] This invention belongs to the field of wind turbine technology, and in particular relates to a multi-space filter box structure for wind turbines. Background Technology

[0002] A wind turbine is an electrical device that converts wind energy into mechanical energy, and then into electrical energy. It is widely used in areas with abundant wind power, such as Finland, Denmark, and parts of western my country. The principle of wind power generation is to use wind power to drive the blades of a windmill to rotate, and then use a speed increaser to increase the rotation speed, thereby causing the generator to produce electricity. Because wind energy is a renewable and pollution-free energy source, it is receiving increasing attention and is being vigorously developed.

[0003] Typically, low-speed, large-diameter generators (e.g., wind turbines) consist of a stator and a rotor. Generators continuously generate heat during operation, and the accumulation of heat can lead to excessively high internal temperatures. High temperatures can shorten the lifespan of many critical components inside the generator. To avoid excessive temperature rise, generators generally...

[0004] For example, CN112302889A discloses a wind turbine filter box structure, including a rectangular box with an opening on one side, and a filter module disposed inside the rectangular box. Several ventilation holes are provided on the bottom side of the rectangular box. A U-shaped fastener is fitted at the open end of the rectangular box. The cross-section of the U-shaped fastener is L-shaped, and the U-shaped fastener and the end face of the rectangular box form a U-shaped groove. A ventilation cover is fitted inside the U-shaped groove. When this filter box structure is in use, after a period of time, the filter module absorbs dust, moisture, etc., and loses its filtering function. Therefore, it is necessary to replace and clean the filter module after a period of use. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-space filter box structure for wind turbines. By providing a filter chamber for filtration and a filter box for storing the filter box within the filter box body, it is convenient to control the filter box located in the filter chamber to be sent into the filter chamber when one filter box loses its filtration function, thus solving the problems raised in the prior art.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0028] 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.

[0029] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0030] Please see Figure 2-3 As shown, the present invention is a multi-space filter box structure for wind turbines, including a filter box body 1, and the filter box body 1 has a through filter cavity 10 and a storage cavity 11 closed at one end. Multiple rectangular channels 14 are provided between the filter cavity 10 and the storage cavity 11, and a filter box 2 can be slidably assembled in any rectangular channel 14. In the above-mentioned use state, the filter box 2 is controlled to be located in the filter cavity 10, and the air is filtered by the filter box 2 installed in the filter cavity 10. At the same time, the filter box 2 in the non-use state is stored in the storage cavity 11. When the filter box 2 located in the filter cavity 10 loses its filtering function, the filter box 2 stored in the storage cavity 11 is controlled to be sent into the filter cavity 10, and then the filter box 2 that has lost its filtering function is controlled to be pulled back into the storage cavity 11.

[0031] In this invention, such as Figure 5 The filter box 2 includes a porous substrate 20. The upper surface of the porous substrate 20 is recessed to form a groove 21. A filter structure 22 is disposed in the groove 21. A porous fixing plate 23 is mounted on the filter structure 22. An insertion hole is provided on the bottom side of the porous substrate 20. The filter structure 22 is used to filter the air. The porous fixing plate 23 is used to facilitate the installation and removal of the filter structure 22.

[0032] To better filter the air, the filter structure 22 consists of a filter cotton layer A, a chemical adsorption layer, and a filter cotton layer B, arranged sequentially from the inside out. Both filter cotton layers A and B are made of P15 / 350S filter cotton. The use of P15 / 350S filter cotton is primarily due to its superior filtration effect and stronger ability to adsorb dust, especially acid mist, from the air. The chemical adsorption layer is filled with calcium oxide particles. This calcium oxide-filled chemical adsorption layer allows for the adsorption of pollutants such as water vapor and sulfur dioxide from the air during the filtration process, preventing these pollutants from entering the wind turbine and causing corrosion, thus damaging the wind turbine and reducing its lifespan. Furthermore, the arrangement of filter cotton layers A and B facilitates the fixation of the calcium oxide particles, preventing long-term weathering dust from entering the wind turbine and causing corrosion.

[0033] In order to determine whether the filter box 2 in use has lost its filtering function, the present invention also provides a detection mechanism for detecting the air permeability of any filter box 2. When in use, the detection mechanism uses gas sensors 106 set at both ends of the filter box 2 to detect the gas conditions on both sides and compare them to determine the performance of the filter box 2.

[0034] To facilitate testing the air permeability of any filter cartridge 2 during use, in actual application, when different filter cartridges 2 are selected, such as... Figure 8 The gas sensor 106 needs to be controlled to perform corresponding activities. That is, the detection mechanism provided by the present invention includes a channel 104 disposed on an inner wall of the filter chamber 10 and along the axial direction of the filter chamber 10. Mounting plates 107 are fixed at both ends of the channel 104 respectively. A rodless cylinder 108 is connected between the two mounting plates 107. A sealing block 105 that slides along the inner wall of the channel 104 is connected to the slider of the rodless cylinder 108. Gas sensors 106 are respectively disposed on the upper and lower sides of the sealing block 105.

[0035] It is known that, as Figure 4 and 6 To facilitate the control of the filter box 2 moving along the axial direction of the rectangular channel 14 during use, a driving mechanism is provided on each of the two opposite inner sidewalls of the filter cavity 10. The driving mechanism includes two first guide rails 12 arranged along the axial direction of the filter cavity 10. A first electric slider 121 is provided on the first guide rail 12. A second guide rail 13 is connected between the two first electric sliders 121. A second electric slider 131 is provided on the second guide rail 13. A telescopic structure 14 is connected to the second electric slider 131. A locking post 15 arranged along the axial direction of the filter cavity 10 is connected to the end of the telescopic structure 14. The bottom of the filter box 2 is provided with an insertion hole for inserting the locking post 15.

[0036] Based on the above, during use, the telescopic structure 14 is controlled to retract, and then the first electric slider 121 is controlled to move on the first guide rail 12, thereby adjusting the telescopic structure 14 to be below the corresponding filter box 2. Then, the telescopic structure 14 is controlled to extend, causing the locking post 15 to be directly below the insertion hole. At this time, the first electric slider 121 is controlled to move on the first guide rail 12 until the locking post 15 is inserted into the insertion hole. Finally, the second electric slider 131 is controlled to move on the second guide rail 13, thereby controlling the filter box 2 to move along the axial direction of the rectangular channel 14.

[0037] Based on the above, the telescopic structure 14 includes a telescopic cylinder 140 mounted on the second electric slider 131, with a mounting cover 141 connected to the end of the telescopic cylinder 140, and a locking post 15 connected to the end of the mounting cover 141; and at least two guide telescopic rods 142 are connected between the mounting cover 141 and the second electric slider 131.

[0038] like Figure 1 To prevent large particles of impurities in the air from entering the filter chamber 10, a metal filter screen 100 is installed at the air inlet of the filter chamber 10; at the same time, to prevent dust from entering the storage chamber 11, a sealing cover plate 200 is installed at the opening of the storage chamber 11.

[0039] It is understood that, based on the above description of the present invention, in order to facilitate the installation and disassembly of the perforated fixing plate 23, a fixing structure for fixing the perforated fixing plate 23 is provided on the two opposite inner sidewalls of the groove 21; such as Figure 7 The fixing structure includes a rectangular groove 24 provided on the inner side wall of the groove 21, and a threaded through hole 241 provided on the bottom side of the rectangular groove 24; a sliding block 26 that slides along the inner side wall of the groove 21 is connected to the bottom side of the rectangular groove 24 by a spring 251, and a bayonet 261 is provided on one side of the sliding block 26; a stud 25 is threadedly connected to the threaded through hole 241, and the end of the stud 25 abuts against the sliding block 26.

[0040] Based on the above, in order to maintain the stability of the filter box 2 after it moves along the axial direction of the rectangular channel 14 and is located in the storage cavity 11 or the filter cavity 10, magnetic blocks A27 are provided at both ends of the porous substrate 20; a slot A101 for inserting the porous substrate 20 is provided on the inner side wall of the filter cavity 10 away from the storage cavity 11; a slot B110 for inserting the porous substrate 20 is provided on the inner side wall of the storage cavity 11 away from the filter cavity 10; magnetic strips A102 and B112 that cooperate with magnetic blocks A27 are respectively installed in slots A101 and B111. The arrangement of slots A101 and B111 facilitates the support of the filter box 2 by the rectangular channel 14; at the same time, the cooperation between magnetic strips A102, B112 and magnetic blocks A27 facilitates the stability of the filter box 2 after installation.
