Description

Technical Field

[0001] This utility model relates to the field of wind power generation technology, and in particular to a wind power monitoring device for new energy wind power generation. Background Technology

[0002] In the prior art, patent CN221465562U discloses a wind power monitoring device for wind farms, including a bracket. A support rod is fixedly connected to one side of the bracket, and an anemometer is fixedly mounted at one end of the support rod. A fixing mechanism is provided on one side of the anemometer, and a fan blade is provided on one side of the anemometer. This device, by setting a fixing mechanism and a pop-out mechanism, allows the threaded rod to disengage from the anemometer by rotating the rotating cap. The spring force in the pop-out mechanism actively disengages the fixing block from the anemometer, and the positioning block gradually disengages from the fan blade as the fixing block moves. This allows damaged fan blades on the anemometer to be removed and replaced, providing a good fan blade replacement mechanism, reducing the hassle of fan blade disassembly and replacement operations, lowering the cost of anemometer replacement, increasing the service life of the anemometer, and improving the normal operating efficiency of the wind power monitoring device.

[0003] In actual use, although the aforementioned equipment can disassemble the fan blades, the rotating cap and fixing block must be removed first before the fan blades can be replaced directly. Disassembling any one fan blade requires disassembling all the others, which is not only time-consuming but also cumbersome. In addition, the existing equipment does not have a defrosting mechanism for the anemometer. When the anemometer is frozen, the lack of a defrosting device will prevent the anemometer from rotating properly, thus affecting its normal use. Utility Model Content

[0004] To address the aforementioned technical problems in the background art, this utility model provides a wind power monitoring device for new energy wind power generation. Its disassembly mechanism has a simple structure, is easy to operate, and can flexibly perform single operations on damaged rotors.

[0005] The technical solution of this utility model is as follows: This utility model is a wind power monitoring device for new energy wind power generation. The wind power monitoring device for new energy wind power generation includes a bracket, on which an anemometer is mounted. A fixed component capable of rotating around the anemometer is mounted on the top of the anemometer. Multiple rotating cups are spaced apart on the fixed component. The special feature is that the fixed component is provided with a disassembly mechanism. The disassembly mechanism includes a mounting groove, which is disposed on the fixed component. The fixed component is provided with a plug-in groove, which is disposed on one side of the mounting groove, close to the plug-in groove. A fixed rod is slidably installed on the inner wall of one side. The inner end of the rotating cup is inserted into the insertion groove. A retaining groove is opened on the inner end of the rotating cup. One end of the fixed rod is inserted into the retaining groove. A positioning curved plate, a worm gear, a lead screw, and a worm are installed in the mounting groove. The positioning curved plate is set on the inner wall of the mounting groove near the insertion groove. The positioning curved plate is equipped with a worm gear that can rotate relative to the curved plate. A lead screw is threaded on the worm gear. One end of the lead screw is connected to the other end of the fixed rod. A rotatable worm is set on the inner wall of the mounting groove. The worm meshes with the worm gear. One end of the worm extends out of the mounting groove.

[0006] Furthermore, the anemometer is equipped with a defrosting mechanism, which includes a heating box fitted onto the anemometer. The heating box has multiple exhaust pipes spaced apart, with the upper ends of the exhaust pipes extending to the bottom of the fixing component. A control plate is provided on the bottom inner wall of the heating box, and an electric heating wire is provided on the control plate. The electric heating wire is located inside the heating box.

[0007] Furthermore, an installation pipe connected to the heating box is provided on one side, and an exhaust fan is installed inside the installation pipe.

[0008] Furthermore, a mounting bracket is installed on the outer top of the anemometer, on which a temperature sensor and an ice thickness sensor are installed. A PLC control unit is installed on the heating box. The output terminals of the temperature sensor and the ice thickness sensor are connected to the input terminals of the PLC control unit. The output terminals of the PLC control unit are connected to the motor on the exhaust fan and the input terminals of the control board, respectively.

[0009] Furthermore, a support frame is installed on the upper outer side of the anemometer, and the exhaust pipe is clipped onto the support frame.

[0010] Furthermore, there are multiple electric heating wires, which are arranged in a ring at intervals on the control panel.

[0011] Furthermore, the positioning curved plate consists of two pieces, which are respectively set on the upper and lower sides of the fixing rod.

[0012] Furthermore, the end of the worm gear extending outside the mounting slot is provided with a hexagonal groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1) This utility model, through the design of a worm gear, worm wheel, lead screw, fixed rod, rotating cup, and retaining groove, allows for easy replacement of the rotating cup on the fixed assembly when a hex wrench is used to rotate the worm gear. The rotation of the worm gear causes the fixed rod to slide out of the retaining groove on the rotating cup, thus easily releasing the damaged rotating cup from the fixed assembly. The damaged rotating cup can then be easily removed from the fixed assembly for replacement. This design is not only simple in structure but also allows for flexible single-operation of the damaged rotating cup without the need to completely disassemble it. It is not only easy to operate but also convenient and quick.

[0015] 2) This utility model, through the arrangement of a heating box, control board, electric heating wire, exhaust fan, ice thickness sensor, temperature sensor and PLC control unit, can heat the air in the heating box by using the electric heating wire driven by the PLC control unit when the exhaust pipe detects ice forming at the rotating connection of the fixed component and the anemometer, and the temperature sensor detects that the outside temperature is low. The heated air can then be blown by the exhaust fan to the rotating connection of the fixed component and the anemometer, thereby thawing the connection between the fixed component and the anemometer. This prevents the connection from freezing due to low outside temperature, which could prevent the fixed component from rotating properly and thus affect the normal use of the anemometer.

A positioning curved plate 54, a worm gear 55, a lead screw 56, and a worm 57 are provided in the installation groove 5. The positioning curved plate 54 is provided on the inner wall of the installation groove 5 near the insertion groove 52. The positioning curved plate 54 consists of two pieces, which are respectively provided on the upper and lower sides of the fixed rod 51. A worm gear 55 that can rotate relative to the positioning curved plate 54 is provided on the positioning curved plate 54. A lead screw 56 is threaded onto the worm gear 55. One end of the lead screw 56 is connected to the other end of the fixed rod 51. A rotatable worm 57 is provided on the inner wall of the mounting groove 5. The worm 57 meshes with the worm gear 55. One end of the worm 57 extends out of the mounting groove 5, and the end of the worm 57 extending out of the mounting groove 5 is provided with a hexagonal groove.

[0027] See Figure 3 , 4In the specific embodiment of this utility model, the anemometer 2 is further provided with a defrosting mechanism, which includes a heating box 6. The heating box 6 is sleeved on the anemometer 2. Multiple exhaust pipes 61 are spaced apart on the heating box 6, and the upper ends of the multiple exhaust pipes 61 extend to the bottom end of the fixing component 3. A support frame 69 is provided on the upper outer side of the anemometer 2, and the exhaust pipes 61 are snapped onto the support frame 69. A control plate 62 is provided on the bottom inner wall of the heating box 6, and electric heating wires 63 are provided on the control plate 62. Multiple electric heating wires 63 are arranged in a ring at intervals on the control plate 62. An installation pipe 64 communicating with the heating box 6 is provided on one side of the heating box 6, and an exhaust fan 65 is provided inside the installation pipe 64. An anemometer 2 has a mounting bracket 67 on its top outer side. A temperature sensor 68 and an ice thickness sensor 610 are mounted on the mounting bracket 67. A PLC control unit 66 is mounted on the heating box 6. The output terminals of the temperature sensor 68 and the ice thickness sensor 610 are electrically connected to the input terminal of the PLC control unit 66 via cables. The output terminal of the PLC control unit 66 is electrically connected to the motor on the exhaust fan 65 and the input terminal of the control board 62 via cables.

[0028] Among them, the PLC control unit 66, control board 62, temperature sensor 68 and ice thickness sensor 610 are all existing circuit structures.

[0029] The working principle of this utility model is as follows: When monitoring wind force using the fixed component 3 on the anemometer 2, if a damaged rotor cup 4 is found on the fixed component 3, the operator only needs to use a hex wrench to engage the worm gear 57 in the hexagonal groove, and then use the hex wrench to rotate the worm gear 57. The worm gear 57 drives the worm wheel 55 on the positioning curved plate 54 to rotate, and the worm wheel 55 drives the lead screw 56 to move to the left. The lead screw 56 drives the fixing rod 51 to slide out of the retaining groove 53 on the rotor cup 4, thus freeing the rotor cup 4 on the fixed component 3. Then, the rotor cup 4 can be directly removed from the fixed component 3. After inserting a new rotor cup 4 into the insertion groove 52, the hex wrench is used again to rotate the worm gear 57 in the opposite direction, causing the fixing rod 51 to slide into the insertion groove 52 on the rotor cup 4, thus achieving reverse rotation. The convenient installation of cup 4 allows for the transmission of data to the PLC control unit 66 when the ice thickness sensor 610 and temperature sensor 68 detect that the ambient temperature is low, causing ice to form at the connection between the fixed component 3 and the anemometer 2. After analysis and processing by the PLC control unit 66, the control board 62 is immediately driven to operate. The control board 62 commands the electric heating wire 63 to operate immediately, thereby heating the air inside the heating chamber 6. At the same time, the PLC control unit 66 commands the exhaust fan 65 to operate, which in turn blows the heated air inside the heating chamber 6 through the exhaust pipe 61 to the rotating connection between the anemometer 2 and the fixed component 3 to thaw the rotating connection between the anemometer 2 and the fixed component 3.
