[0001] This utility model relates to the field of wind turbine monitoring technology, and in particular to a multi-parameter, high-precision, integrated, fully sensing wind turbine monitoring device. Background Technology

[0002] A fan is a machine that uses input mechanical energy to increase gas pressure and discharge gas. It is a type of driven fluid machinery. In China, it is a common abbreviation for gas compression and gas transportation machinery. The term "fan" usually includes ventilators, blowers, and wind turbines.

[0003] During operation, the fan blade speed, airflow velocity, and shaft eccentricity all affect the fan's efficiency. In conventional environments, minor deviations in fan operation have little impact; however, in applications requiring high airflow velocity, the fan's operating status is crucial, thus necessitating monitoring of its operating parameters.

[0004] Existing monitoring equipment is mostly split-type, using individual sensors to monitor data such as the fan's rotation speed, wind speed, and shaft eccentricity during operation. This is very inconvenient to install and takes up a lot of space.

[0005] Therefore, this application proposes a multi-parameter, high-precision, integrated, fully sensing wind turbine monitoring device to improve the convenience of wind turbine status monitoring. Utility Model Content

[0006] In view of the shortcomings of the prior art mentioned above, the purpose of this utility model is to provide a multi-parameter, high-precision, integrated, all-sensing wind turbine monitoring device to solve the problem of inconvenient wind turbine monitoring mentioned in the prior art.

[0007] To achieve the above and other related objectives, this utility model provides a multi-parameter, high-precision, integrated, fully sensing wind turbine monitoring device, including a data transmission unit and a rotating shaft connecting sleeve. The data transmission unit is equipped with a power distribution unit, and the power distribution unit is equipped with a support bridge. A plurality of electromagnetic plates are equidistantly arranged on the inner wall of the support bridge. The electromagnetic plates are signal-connected to the data transmission unit. A wind speed monitor is provided on the outer surface of the support bridge, and the wind speed monitor is signal-connected to the data transmission unit.

[0008] The outer surface of the rotating shaft connecting sleeve is provided with several permanent magnets at equal intervals;

[0009] The data transmission unit is installed on the outer surface of the fan, and the support bridge is located inside the fan. The support bridge is concentrically arranged with the fan shaft and covers the outside of the fan shaft.

[0010] The rotating shaft connecting sleeve is interference-fitted onto the rotating shaft of the fan, and the electromagnetic plate and permanent magnet are magnetically induced.

[0011] Preferably, the data transmission unit and the power distribution unit are connected in a separable manner, and the bottom surface of the data transmission unit is provided with a mounting baffle, which is connected to the outer surface of the fan.

[0012] Preferably, the data transmission unit transmits and receives data via wired or wireless means, and the power distribution unit is connected to an external power source.

[0013] Preferably, a cable extends from the side of the power distribution unit, and the power distribution unit is connected to the motor of the fan via the cable, and the power distribution unit can control the start and stop of the fan.

[0014] Preferably, the support bridge is semi-circular, and the electromagnetic plates are equidistantly distributed along the inner wall of the semi-circular support bridge.

[0015] Preferably, the support bridge has a wiring channel inside, one end of the electromagnetic plate extends into the wiring channel, and the wiring of the electromagnetic plate is led to the power distribution section along the inner wall of the wiring channel.

[0016] Preferably, the wind speed monitor is installed at the opening of the wiring channel and is located on the windward side of the fan.

[0017] Preferably, the wind speed monitor includes a windward plate, which is slidably installed inside the wiring channel. A pressure transmission rod is provided on the side of the windward plate facing the wiring channel, and a pressure sensor is provided at the end of the pressure transmission rod.

[0018] The pressure sensor is fixed to the inner wall of the wiring channel and is connected to the data transmission unit.

[0019] Preferably, there are multiple pressure transmission rods, and the multiple pressure transmission rods are distributed at equal intervals.

[0020] As described above, the multi-parameter, high-precision, integrated, all-sensing wind turbine monitoring device of this utility model has the following beneficial effects:

[0021] 1. This utility model installs a shaft connecting sleeve on the shaft of a fan, and sets several permanent magnets at equal intervals on the outer surface of the shaft connecting sleeve. By setting a support bridge, several electromagnetic plates are set at equal intervals on the inner wall of the support bridge. When the fan rotates, the shaft connecting sleeve will rotate accordingly, thereby cutting the magnetic lines of the electromagnetic plates through the permanent magnets, thus monitoring the fan speed and the eccentricity of the fan shaft. This achieves the effect of simultaneous detection of speed and shaft eccentricity, improving the convenience of installation.

[0022] 2. This utility model sets up a wind speed monitor on the support bridge and positions the wind speed monitor facing the windward side of the fan. When the fan is working and transporting gas, the gas will exert pressure on the wind speed monitor. The airflow velocity can be calculated through the pressure, which further realizes the integration of the equipment, improves the convenience of equipment installation and reduces the space occupied by the equipment.

[0023] 3. This utility model provides support for the windward plate by setting multiple pressure transmission rods on the back of the windward plate and setting a pressure sensor at the end of each pressure transmission rod. When the windward plate is subjected to gas pressure, the windward plate will apply pressure evenly to the pressure transmission rod and transmit the pressure to the pressure sensor through the pressure transmission rod. The wind speed is calculated by calculating the average pressure, thereby improving the accuracy of monitoring.

[0024] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value. Attached Figure Description

[0033] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0034] Please see Figures 1 to 6 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0035] like Figures 1-4 As shown, this utility model provides a multi-parameter, high-precision, integrated, fully sensing wind turbine monitoring device, including a data transmission unit 11 and a shaft connecting sleeve 16. The data transmission unit 11 is installed on the outer casing of the wind turbine, and the shaft connecting sleeve 16 is installed on the shaft of the wind turbine fan. A power distribution unit 12 is provided on the data transmission unit 11. The power distribution unit 12 is an intelligently controllable switching power supply. The power distribution unit 12 is connected to an external power source to supply power to the power-consuming components in the monitoring device. A support bridge 13 is provided on the power distribution unit 12. Several electromagnetic plates 14 are equidistantly arranged on the inner wall of the support bridge 13. The electromagnetic plates 14 generate magnetism through power supply from the power distribution unit 12. The electromagnetic plates 14 are signal-connected to the data transmission unit 11. The electromagnetic plates 14 generate magnetic energy fluctuations due to magnetic cutting, and the magnetic energy fluctuation signal is transmitted to the data transmission unit 11. A wind speed monitor 18 is provided on the outer surface of the support bridge 13 to monitor wind pressure. The wind speed monitor 18 is signal-connected to the data transmission unit 11 to transmit wind pressure data to the data transmission unit 11.

[0036] The data transmission unit 11 is installed on the outer surface of the fan, and the support bridge 13 is located inside the fan. The support bridge 13 is concentrically arranged with the fan shaft and covers the outside of the fan shaft, thereby reducing the space occupied by the monitoring equipment.

[0037] A rotating shaft connecting sleeve 16 is interference-fitted onto the fan shaft. Several permanent magnets 17 are equidistantly arranged on the outer surface of the sleeve 16. When the sleeve rotates with the fan shaft, the permanent magnets 17 rotate accordingly. At this time, the electromagnetic plate 14 experiences magnetic shear due to the rotation of the permanent magnets 17, generating magnetic induction between them. During monitoring, the fan speed is determined based on the frequency of the magnetic shearing of the permanent magnets 17 onto the electromagnetic plate 14. Simultaneously, the eccentricity of the fan shaft is calculated based on the stability of the magnetic shearing. When the fan shaft is eccentric, its rotation will produce vibration, which will cause a change in the distance between the permanent magnets 17 and the electromagnetic plate 14, thus determining the eccentricity of the fan shaft. The principle for monitoring fan speed and eccentricity can be referenced from the Hall effect sensing principle.

[0038] The data transmission unit 11 and the power distribution unit 12 are connected in a detachable manner. During installation, the power distribution unit 12 is installed from inside the fan, while the data transmission unit 11 is installed from outside the fan. The data transmission unit 11 and the power distribution unit 12 are connected together by screws and fixed to the fan casing. The bottom surface of the data transmission unit 11 is provided with a mounting baffle 15, which is connected to the outer surface of the fan to further improve the stability of the equipment installation. The mounting baffle 15 also seals the connection between the data transmission unit 11 and the power distribution unit 12, improving the waterproofness of the equipment.

[0039] The data transmission unit 11 sends and receives data via wired or wireless means, thereby transmitting the monitored data to an external data monitoring platform and receiving instruction information issued by the data monitoring platform. Wired data transmission can improve the stability and anti-interference of data transmission, while wireless remote data transmission can improve the ease of use of the device. The specific transmission method is set according to actual needs.

[0040] like Figure 2 As shown, in some embodiments, cables extend from the side of the power distribution unit 12 of this utility model. The power distribution unit 12 is connected to the motor of the fan through the cables, and the power distribution unit 12 can control the start and stop of the fan. This integrates the power supply of the fan and the monitoring equipment, reducing the space occupied by the equipment. The operation of the fan can be controlled by the monitoring equipment. When a logic module is installed in the data transmission unit 11, the start and stop and speed of the fan can be controlled automatically by the monitoring data and the logic module, so that the fan can be intelligently controlled.

[0041] like Figures 2-3 As shown, in some embodiments, the support bridge 13 of this utility model is semi-circular to form a semi-circular enclosure for the fan shaft. The electromagnetic plates 14 are equidistantly distributed along the inner wall of the semi-circular support bridge 13 to make the distance between the electromagnetic plates 14 and the permanent magnet 17 equal and to increase the monitoring range.

[0042] like Figure 5 As shown, in some embodiments, the support bridge 13 of this utility model has a wiring channel 131 inside. The wiring channel 131 is a cavity with an opening on the windward side. One end of the electromagnetic plate 14 extends into the wiring channel 131, and the wires of the electromagnetic plate 14 are led to the power distribution unit 12 along the inner wall of the wiring channel 131. The power distribution unit 12 supplies power to the electromagnetic plate 14, causing the electromagnetic plate 14 to generate magnetism. When the permanent magnet 17 with magnetism rotates, it can cut the magnetic field generated by the electromagnetic plate 14. The data of cutting the electromagnetic plate 14 is transmitted to the data transmission unit 11 through the data line. The rotation speed of the fan is determined by the frequency of magnetic cutting, and the fan shaft is determined by the amount of magnetic deflection.

[0043] like Figure 3 and Figure 4 As shown, in some embodiments, the wind speed monitor 18 of this utility model is installed at the opening of the wiring channel 131 and the wind speed monitor 18 is located on the windward side of the fan. When the fan delivers gas, the flowing gas will generate air pressure. The wind speed can be calculated by the pressure exerted by the air pressure on the wind speed monitor 18 per unit area.

[0044] like Figure 6 As shown, in some embodiments, the wind speed monitor 18 of this utility model includes a windward plate 181, which is slidably installed inside the wiring channel 131, and the outer surface of the windward plate 181 is tightly fitted with the inner wall of the wiring channel 131. A pressure transmission rod 182 is provided on the side of the windward plate 181 facing the wiring channel 131, and a pressure sensor 183 is provided at the end of the pressure transmission rod 182. The pressure sensor 183 is fixed to the inner wall of the wiring channel 131, and the pressure transmission rod 182 is used to support the windward plate 181. When the windward plate 181 is pressed and moves, it will apply pressure to the pressure sensor 183 through the pressure transmission rod 182. The pressure sensor 183 generates different resistance values ​​according to different pressure levels, which are used to determine the pressure value. The pressure sensor 183 is signal-connected to the data transmission unit 11 to transmit the pressure value to the data transmission unit 11 so as to calculate the wind speed based on the pressure.

[0045] like Figure 6 As shown, in some embodiments, the present invention has multiple pressure transmission rods 182, which are equidistantly distributed. The multiple pressure transmission rods 182 jointly support the windward plate 181, so that the pressure on the windward plate 181 can be evenly transmitted to all pressure sensors 183. The wind pressure is calculated by the average value of all pressure sensors 183 to improve the accuracy of the data.

[0046] In summary, the multi-parameter, high-precision, integrated, all-sensing fan monitoring device of this invention, by installing a shaft connecting sleeve 16 on the fan shaft and equidistantly arranging several permanent magnets 17 on the outer surface of the shaft connecting sleeve 16, and by setting a support bridge 13 and equidistantly arranging several electromagnetic plates 14 on the inner wall of the support bridge 13, when the fan rotates, the shaft connecting sleeve 16 will rotate accordingly, thereby cutting the magnetic lines of the electromagnetic plates 14 through the permanent magnets 17, thus monitoring the fan speed and the fan shaft eccentricity, achieving the effect of simultaneous detection of speed and shaft eccentricity, and improving the ease of installation.

[0047] This utility model integrates the equipment by setting a wind speed monitor 18 on the support bridge 13 and facing the windward side of the fan. When the fan is working and transporting gas, the gas will exert pressure on the wind speed monitor 18. The airflow velocity can be calculated by the pressure. This further improves the convenience of equipment installation and reduces the space occupied by the equipment.

[0048] This invention provides support for the windward plate 181 by setting multiple pressure transmission rods 182 on the back side of the windward plate 181, and setting a pressure sensor 183 at the end of each pressure transmission rod 182. When the windward plate 181 is subjected to gas pressure, the windward plate 181 will apply pressure evenly to the pressure transmission rods 182, and the pressure will be transmitted to the pressure sensor 183 through the pressure transmission rods 182. The wind speed is calculated by calculating the average pressure, thereby improving the accuracy of monitoring.

[0049] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0050] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
