Description

Technical Field

[0001] This utility model relates to the field of ceiling fan equipment technology, specifically to an industrial fan temperature monitoring device. Background Technology

[0002] In industrial environments, ceiling fans are common ventilation and cooling devices, and their stable operation is crucial for ensuring work environment comfort and production efficiency. However, during prolonged, high-load operation, the motor generates heat due to the current flowing through it. If heat dissipation is poor or the load is too heavy, the motor temperature can easily rise sharply. Overheating not only reduces its efficiency and shortens its lifespan, but in severe cases, it can also cause electrical faults and even equipment damage, affecting production safety. Therefore, real-time monitoring of ceiling fan motor temperature and timely detection and handling of overheating issues are of great significance for preventing equipment failure and ensuring production safety.

[0003] Currently, there are several technologies available on the market for monitoring motor temperature. These technologies can be broadly categorized as follows:

[0004] Thermometer method: This is the simplest method, using a thermometer to directly measure the temperature on the motor surface. However, this method only reflects the surface temperature of the motor and cannot accurately reflect the true internal temperature of the motor, especially for large industrial ceiling fans, where the internal temperature of the motor is often much higher than the surface temperature.

[0005] Embedded thermometer method: For larger motors, thermometers, such as thermocouples or resistance thermometers, can be embedded in locations where high temperatures are expected to be generated during assembly. This method can measure the internal temperature of the motor more accurately, but it requires installation during motor manufacturing or repair, making the operation more complex, and it is difficult to modify ceiling fans that are already in use.

[0006] Resistance method: This method estimates temperature by measuring changes in the resistance of the motor windings. The resistance of the motor windings increases with temperature. This method requires measuring the cold resistance of the motor windings beforehand and periodically measuring the hot resistance during operation, then calculating the temperature by comparison. However, this method has high real-time requirements, and its measurement accuracy is affected by various factors.

[0007] However, most of these temperature measuring devices can only be powered off when the temperature is high, and cannot monitor and display the temperature in real time because the rotation of the fan blades can obstruct the view, thus failing to provide an effective warning to the workers. Utility Model Content

[0008] To address the aforementioned issues, this utility model provides an industrial fan temperature monitoring device that can monitor the motor temperature in real time during ceiling fan operation, preventing equipment damage due to motor overheating.

[0009] To achieve the above objectives, the present invention adopts the following technical solution: an industrial fan temperature monitoring device, comprising a suspension rod and a ceiling fan body, wherein a drive assembly is provided between the suspension rod and the ceiling fan body, the drive assembly includes a drive source, a protective housing is provided outside the drive source, a temperature detection module is provided inside the protective housing, and an anti-fall bearing sleeve connected to the ceiling fan body is provided at the lower part of the protective housing.

[0010] As a further improvement to the above technical solution:

[0011] The temperature detection module includes a temperature sensor and a controller, which are electrically connected. An alarm panel electrically connected to the controller is provided on the outside of the protective housing.

[0012] The warning panel is equipped with a warning light, and the upper part of the protective housing is provided with a storage cavity for placing the warning panel, and a protective cover is provided at the opening of the storage cavity.

[0013] The outer wall of the protective housing is provided with heat dissipation protrusions, and the number of heat dissipation protrusions is multiple and they are evenly distributed along the height direction of the protective housing.

[0014] The upper part of the anti-fall bearing sleeve is provided with a limiting ring plate 1 located inside the protective housing, and the middle part of the anti-fall bearing sleeve is provided with a limiting ring plate 2 located below the protective housing.

[0015] The lower part of the protective shell is provided with a mounting base plate, and the mounting base plate is provided with a snap-fit ​​protrusion corresponding to a position of the limiting ring plate.

[0016] The lower part of the protective shell is provided with a support plate located below the second limiting ring plate. The middle part of the support plate is provided with a through hole, the diameter of which is smaller than the diameter of the second limiting ring plate.

[0017] The beneficial effects of this utility model embodiment are as follows: The industrial fan temperature monitoring device includes a suspension rod and a ceiling fan body. A drive assembly is installed between the suspension rod and the ceiling fan body. The drive assembly includes a drive source, which is a motor. A protective shell is provided outside the drive source. A temperature detection module is installed inside the protective shell to detect the real-time temperature of the drive source during operation. The lower part of the protective shell is provided with an anti-fall bearing sleeve connected to the ceiling fan body. The transmission between the drive source and the ceiling fan body is realized through the anti-fall bearing sleeve. The protective shell can seal and protect the drive source during use, avoiding the influence of impurities and dust that may cause the drive source to operate normally. The temperature detection module can monitor the temperature of the sealed drive source, preventing damage caused by the reduced heat dissipation efficiency of the drive source after sealing and the increased temperature after long-term operation.

[0023] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0024] like Figure 1-4 As shown, the industrial fan temperature monitoring device of this embodiment includes a suspension rod 1 and a ceiling fan body 2. A drive assembly is installed between the suspension rod 1 and the ceiling fan body 2. The drive assembly includes a drive source 3, which is a motor. The drive source 3 is provided with a protective housing 4. A temperature detection module is installed inside the protective housing 4 to detect the real-time temperature of the drive source 3 during operation. The lower part of the protective housing 4 is provided with an anti-fall bearing sleeve 5 connected to the ceiling fan body 2. The transmission between the drive source 3 and the ceiling fan body 2 is realized through the anti-fall bearing sleeve 5. The protective housing 4 can seal and protect the drive source 3 during use, avoiding the influence of impurities and dust that may cause the drive source 3 to operate normally. The temperature detection module can monitor the temperature of the sealed drive source 3, preventing damage due to reduced heat dissipation efficiency after sealing and temperature rise after long-term operation.

[0025] The temperature detection module includes a temperature sensor 6 and a controller 7. The controller 7 and the temperature sensor 6 are electrically connected. The protective housing 4 has an external warning panel 8 that is electrically connected to the controller 7. After the temperature sensor 6 collects the operating temperature of the drive source 3, it transmits it to the controller 7. When the detected temperature exceeds the preset temperature value, the controller 7 will send a command to the warning panel to remind the operator to turn off the fan or reduce the fan speed.

[0026] The warning panel 8 is equipped with a warning light 9. The upper part of the protective housing 4 is provided with a storage cavity 10 for placing the warning panel 8. The opening of the storage cavity 10 is covered with a protective cover 11, which is made of transparent material. There are at least three warning lights, which are used to represent three operating states of the drive source (i.e., green for normal operation, yellow for temperature above normal operation but below the set value, and red when the detected temperature is above the set value). The different colors are used to display the operating temperature of the drive source 3, which serves as a warning. When the operating temperature is too high for 0.5-1 hour, the drive source 3 will activate the overheat protection and stop operating.

[0027] The outer wall of the protective housing 4 is provided with heat dissipation protrusions 12. There are multiple heat dissipation protrusions 12, which are evenly distributed along the height direction of the protective housing 4. The function of the heat dissipation protrusions 12 is to increase the surface area of ​​the protective housing 4 and enhance the heat dissipation effect of the protective housing 4.

[0028] The upper part of the anti-fall bearing sleeve 5 is provided with a limiting ring plate 13 located inside the protective housing 4, and the middle part of the anti-fall bearing sleeve 5 is provided with a limiting ring plate 24 located below the protective housing 4. The limiting ring plate 13 and the limiting ring plate 24 are used to improve the connection strength between the ceiling fan body 2 and the drive source 3, and prevent the ceiling fan body 2 from falling off after the shaft breaks.

[0029] The lower part of the protective housing 4 is provided with a mounting base plate 15. The mounting base plate 15 is provided with a snap-fit ​​boss 16 corresponding to the position of the limiting ring plate 13. The snap-fit ​​boss 16 is provided with an inner recess that cooperates with the limiting ring plate 13. The limiting ring plate 13 is placed in the inner recess and then locked with bolts to ensure that the anti-fall bearing sleeve 5 is connected to the mounting base plate 15. This replaces the direct connection of the ceiling fan body 2 to the drive source 3, reduces the downward tension on the drive shaft, and improves the service life of the drive shaft.

[0030] The lower part of the protective housing 4 is provided with a support plate 17 located below the second limiting ring plate 14. The middle part of the support plate 17 is provided with a through hole 18 for passing through the anti-fall bearing sleeve 5. The diameter of the through hole 18 is smaller than the diameter of the second limiting ring plate 14. The design of the second limiting ring plate 14 and the support plate 17 can further improve the connection strength between the anti-fall bearing sleeve 5 and the protective housing 4, and at the same time, it can also share the downward tension of the first limiting ring plate 13.
