Description

Technical Field

[0001] The utility model relates to the technical field of installation structures, in particular to an installation structure of an anemometer in a wind power generation unit. Background Technique

[0002] The anemometer of the wind power generation unit should be installed at the top of the wind turbine. This choice is based on the influence of the installation position of the anemometer on the accuracy of wind speed measurement and the performance of the wind turbine. The anemometer installed at the top of the wind turbine can directly feel the strongest wind force and provide the most real wind speed data, which is crucial for the wind turbine to realize functions such as automatic wind alignment and cable untying. In addition, this installation position also helps the anemometer to more accurately reflect the actual wind direction and wind speed, thereby improving the wind energy conversion efficiency and ensuring the efficient operation of the wind turbine.

[0003] The existing technology adopts a screw connection method for the installation of the anemometer. There are some drawbacks to this installation method. The anemometer and its installation structure are exposed to the air and are eroded by wind, rain and dust for a long time. The screw connection is prone to rust and stickiness. Once the anemometer fails, it is very difficult for personnel to disassemble and replace it, affecting the maintenance and replacement efficiency. In addition, the anemometer is affected by winds from different directions for a long time, and the force direction changes frequently, which may cause the screws to loosen.

[0019] Such as Figures 1-3As shown in the figure, an installation structure of an anemometer 11 in a wind turbine generator set includes a housing 1 of the wind turbine generator set, a plurality of first compression springs 4, a pair of support plates 3, an anemometer 11, a connection sensing system 12, a bottom plate 14 and a pair of sliding plates 13. A rectangular installation groove 5 is formed on the housing 1. Slots 6 are horizontally formed on the left and right side walls of the installation groove 5. A plurality of first compression springs 4 are evenly arranged between the pair of support plates 3, and the support plates 3 are seated on the bottom of the installation groove 5. The upper support plate 3 is higher than the height where the slots 6 are located. The bottom of the anemometer 11 is connected to the center position of the upper surface of the bottom plate 14 through the connection sensing system 12. A cover plate 10 with a size larger than that of the installation groove 5 is pre-actively sleeved on the anemometer 11. A pair of sliding plates 13 are respectively horizontally slidably connected to the upper surface of the bottom plate 14 through sliding members. A plurality of second compression springs 16 are arranged between the pair of support plates 3. Retracting the pair of sliding plates 13 inward and simultaneously pressing the bottom plate 14 downward to press the support plates 3 downward can make the sliding plates 13 inserted into the slots 6, and the cover plate 10 can cover the installation groove 5. A groove 17 with a diameter larger than the length of the installation groove 5 is formed on the housing 1. The side wall of the groove 17 is provided with internal threads. The cover plate 10 is disk-shaped, and an external thread is provided on the edge of the cover plate 10. The cover plate 10 is screwed into the groove 17. A rubber pad 9 is arranged between the cover plate 10 and the sliding plate 13, and the rubber pad 9 is matched with the size of the installation groove 5. The sliding member includes a slide bar 7. The slide bar 7 is arranged on the upper surface of the bottom plate 14 and faces the direction of the slots 6. A chute 8 is formed at the bottom of the sliding plate 13, and the slide bar 7 is slidably connected to the chute 8. A hand-holding groove 15 is formed on the sliding plate 13. A plurality of telescopic rods 2 are evenly arranged between the pair of support plates 3, and the first compression springs 4 are sleeved on the telescopic rods 2.

[0020] The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, which are as follows:

[0021] According to the attached drawings of the specification Figures 1-3It can be seen that when the utility model is installed, the anemometer 11 is connected to the center position of the upper surface of the bottom plate 14 through the connection sensing system 12. The connection sensing system 12 is used to monitor the operation of the anemometer 11, including wind direction and wind speed, and transmit signals. This is prior art. Here, a cover plate 10 needs to be sleeved on the anemometer 11 in advance for subsequent sealing treatment. A handle for convenient buckling or rotation can be provided on the cover plate 10, which can also be achieved by prior art and will not be elaborated here. A plurality of first compression springs 4 are evenly arranged between a pair of support plates 3, which are also pre-made. During installation, they are placed into the installation groove 5 together. The operator manually retracts a pair of sliding plates 13 inward, and the second compression spring 16 is compressed, so that the bottom plate 14 and the pair of sliding plates 13 are inserted into the installation groove 5 together. The bottom plate 14 presses down on the support plate 3 until the sliding plate 13 is level with the slot 6. The sliding plate 13 is pushed into the slot 6 by the reaction force of the second compression spring 16. The sizes of the slot 6 and the sliding plate 13 are matched. Since the sliding plate 13 is horizontally slidably connected to the bottom plate 14 through a sliding member, the slot 6 can limit the sliding plate 13 and the bottom plate 14 in the vertical direction. Since the upper support plate 3 is higher than the height where the slot 6 is located, pressing down the pressing plate on the support plate 3 will compress the first compression spring 4. After the sliding plate 13 is inserted into the slot 6, the reaction force of the first spring causes the sliding plate 13 to be tightly pressed against the upper wall of the slot 6 to maintain stability. During design, the sizes of the bottom plate 14 and the installation groove 5 are matched, so the installation groove 5 can limit the bottom plate 14 in the horizontal direction to keep it stable. Finally, the cover plate 10 is buckled on the installation groove 5 to ensure the sealing inside the installation groove 5 and prevent rainwater from entering. Limiting and fixing the bottom plate 14 is to limit and fix the anemometer 11. The utility model limits the bottom plate 14 of the anemometer 11 in the horizontal direction through the installation groove 5, and the reaction force of the first compression spring 4 causes the sliding plate 13 to be tightly pressed in the slot 6 in the vertical direction, thereby limiting the bottom plate 14 in the vertical direction. The installation is stable. During installation, the operator directly presses the bottom plate 14 into the installation groove 5, and the sliding plate 13 is inserted into the slot 6 by the action of the second compression spring 16. During disassembly, the operator only needs to pull back the sliding plate 13. The installation method is simple, convenient, and fast, improving the efficiency of disassembly and installation.

[0022] Among them, a groove 17 with a diameter larger than the length of the installation groove 5 is formed on the outer shell 1. Internal threads are provided on the side wall of the groove 17. The cover plate 10 is disc-shaped, and external threads are provided on the edge of the cover plate 10. The cover plate 10 is screwed into the groove 17. Of course, if further considering the quickness of installation and disassembly here, a rubber sealing ring can also be provided on the edge of the cover plate 10 and be press-fitted into the groove 17 in an interference fit manner.

[0023] Among them, a rubber pad 9 is arranged between the cover plate 10 and the sliding plate 13. The rubber pad 9 is matched with the installation groove 5 in size. The rubber pad 9 can not only improve the sealing effect, but also has a certain elasticity, giving an axial force to the cover plate 10 to make its screwed connection with the housing 1 tighter and avoid loosening.

[0024] Among them, the sliding member includes a slide bar 7. The slide bar 7 is arranged on the upper surface of the bottom plate 14 and faces the direction of the slot 6. A chute 8 is formed at the bottom of the sliding plate 13. The slide bar 7 is slidably connected with the chute 8. This ensures the stability between the sliding plate 13 and the bottom plate 14, mainly the stability in the axial direction.

[0025] Among them, a hand - holding groove 15 is formed on the sliding plate 13, which is convenient for personnel to slide the sliding plate 13.

[0026] Among them, a plurality of telescopic rods 2 are evenly arranged between a pair of support plates 3. The first compression spring 4 is sleeved on the telescopic rod 2. The telescopic rod 2 ensures that when the bottom plate 14 presses the support plate 3, the support plate 3 and the first compression spring 4 will not shift, affecting the resilience effect of the first compression spring 4.
