Description

Technical Field

[0001] This invention relates to the field of generator set monitoring technology, and in particular to an early warning response device for monitoring the carbon brushes of the collector rings in generator sets. Background Technology

[0002] The slip rings are mounted on the rotor shaft and rotate with the rotor. The carbon brushes are fixed to the stationary part of the generator and pressed tightly against the surface of the slip rings by springs to ensure current transmission. By collecting and analyzing equipment operating data in real time, the safe, stable and efficient operation of the equipment is ensured, while maintenance strategies are optimized and operating costs are reduced.

[0003] When the generator set is working, it is necessary to promptly report any abnormal data. When the humidity inside the generator set is too high, it can easily cause oxidation, corrosion, and carbon powder accumulation on the carbon brushes of the slip ring. When dehumidification is carried out using desiccant, the desiccant is placed inside the generator set and needs to be replaced regularly. Manual replacement is cumbersome and requires stopping the machine to perform the operation. In addition, the desiccant in different locations has different usage levels. When the air humidity is high at the air intake, the desiccant reaches saturation faster and loses its moisture absorption capacity. Subsequently, due to the decrease in air humidity, the desiccant absorbs less water, resulting in low utilization rate. Direct replacement of the desiccant would lead to waste. Summary of the Invention

[0004] The problem solved by this invention is to provide an early warning response device for monitoring the carbon brushes of the slip rings in generator sets. This device addresses the need for timely feedback of abnormal data during generator set operation. When the humidity inside the generator set is too high, it easily causes oxidation, corrosion, and carbon powder accumulation on the carbon brushes of the slip rings. Furthermore, when dehumidifying with desiccants, the desiccant is placed inside the generator set and needs to be replaced periodically. Manual replacement is cumbersome and requires shutdown. Additionally, the desiccant's utilization level varies in different locations; at the air intake area, the high humidity causes the desiccant to reach saturation faster and lose its moisture absorption capacity. Subsequently, as the air humidity decreases, the desiccant's absorption capacity decreases, resulting in low utilization and waste from direct replacement.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An early warning response device for monitoring the carbon brushes of a generator set's slip ring includes an external controller, an early warning device, and a dehumidification mechanism. The external controller is electrically connected to the early warning device and the dehumidification mechanism. The dehumidification mechanism includes a base mounted on the outside of the generator set via a support arm. A turntable is rotatably mounted on the outside of the base, and a circular groove is formed on the turntable. A drying component is rotatably mounted in the circular groove. A bidirectional pneumatic cylinder is mounted at the center of the base. A first translation plate is mounted on the top telescopic end of the bidirectional pneumatic cylinder. A first sleeve is mounted on one end of the first translation plate, and a first sealing cover is mounted on the bottom end of the first sleeve. A first air pipe communicating with the generator set's casing is slidably mounted inside the first sleeve, and a fan is mounted on the first air pipe. A second translation plate is mounted on the bottom telescopic end of the bidirectional pneumatic cylinder. A second sleeve is mounted on one end of the second translation plate, and a second sealing cover is mounted on the top end of the second sleeve. A second air pipe communicating with the generator set's casing is slidably mounted inside the second sleeve.

[0007] Preferably, the external controller is equipped with a display screen, and the external controller is electrically connected to multiple sets of sensors inside the generator set.

[0008] Preferably, a feeding pipe is installed at the other end of the first translation plate, a material cylinder for storing desiccant is installed on the feeding pipe, and a material valve is installed on the feeding pipe.

[0009] Preferably, a discharge pipe is installed at the other end of the second translation plate, and a material collection hood is installed on the discharge pipe.

[0010] Preferably, the base and the turntable are connected by bearings, a toothed ring is provided on the top side of the base, a first motor is installed on the bottom side of the base, and a rotating tooth is installed at the output end of the first motor, and the rotating tooth meshes with the toothed ring.

[0011] Preferably, the drying assembly includes a storage cylinder, and air grooves are provided on the top and bottom sides of the storage cylinder. A mounting frame is symmetrically installed on the outside of the storage cylinder, and a rotating shaft is installed on the mounting frame. A second motor is installed inside the turntable, and the output end of the second motor is connected to the rotating shaft.

[0012] Preferably, the storage cylinder has a first material hole and a second material hole symmetrically opened on both sides of its outer surface, and a cylinder ring is rotatably installed on the outer side of the storage cylinder, and the cylinder ring has a third material hole and a fourth material hole.

[0013] Preferably, the storage cylinder and the cylinder ring are connected by a bearing, the outer side of the cylinder ring is provided with external teeth, the storage cylinder is mounted with a mounting plate, the mounting plate is mounted with a third motor, the output end of the third motor is mounted with a drive tooth, and the drive tooth meshes with the external teeth.

[0014] Preferably, when the second and fourth feed holes coincide, the first and third feed holes are staggered.

[0015] Preferably, the specific operating steps of the device are as follows:

[0016] Step 1: Multiple sensors installed in the generator set monitor the temperature, humidity, dust, noise, and other environmental factors of the slip rings and carbon brushes. Based on the monitoring data, the slip rings and carbon brushes are adjusted in real time. If the temperature is abnormal and continues to rise too high, an alarm will be triggered to remind maintenance personnel to pay close attention and shut down for maintenance. If the humidity is too high, the dehumidification mechanism will be used to remove moisture to ensure the stable operation of the generator set.

[0017] Step 2: The first and second translation plates are moved by the operation of the bidirectional pneumatic cylinder. The drying component between the first and second sealing covers is in a horizontal state. The drying component between the feeding pipe and the collecting cover is rotated to a vertical state by the action of the second motor. At this time, the first translation plate moves the first sleeve and the feeding pipe downward, and the second translation plate moves the second sleeve and the collecting cover upward. At this time, the first and second sealing covers are outside the horizontally set storage cylinder. The bottom end of the feeding pipe corresponds to the first material hole of the vertically set storage cylinder, and the collecting cover corresponds to the second material hole of the vertically set storage cylinder.

[0018] Step 3: The fan operates to transport the humid air inside the generator set through the air trough to the storage cylinder. The desiccant in the storage cylinder removes the moisture in the air, and the dried air is transported back to the generator set through the second sealing cover and the second sleeve, thus dehumidifying the air inside the generator set. The third motor operates to drive the drive gear to rotate, which engages with the meshing external gear to rotate the cylinder ring. At this time, the fourth material hole on the cylinder ring rotates to correspond with the second material hole. The desiccant in the vertically set storage cylinder falls into the collection hood and discharge pipe through the second and fourth material holes and is discharged. Then the cylinder ring continues to rotate until the first material hole corresponds with the third material hole. The material valve is opened, and the desiccant in the material cylinder enters the storage cylinder through the first and third material holes, realizing the automatic filling and replacement of the desiccant.

[0019] Step 4: After the first translation plate moves up and the second translation plate moves down, the horizontally set drying component is rotated 360° and then used to replace the desiccant in the storage cylinder. After the desiccant is replaced, the vertically set drying component is rotated 180° and then set horizontally. During use, the first motor drives the rotating gear to rotate, which cooperates with the meshing gear ring to drive the turntable to rotate on the base, making it easy to interchange the positions of the two drying components.

[0020] The beneficial effects of this invention are: monitoring the working environment inside the generator set, adjusting the slip ring and carbon brush in real time based on the monitoring data, alarming the maintenance personnel to pay close attention and shut down for maintenance when the temperature is abnormal and continues to rise too high, and removing moisture through the dehumidification mechanism when the humidity is too high, thus ensuring the stable operation of the generator set.

[0021] The rotation of the turntable facilitates the interchange of the two drying components, enabling them to perform air drying and desiccant replacement and refilling separately. The second motor rotates the drying components 180°, and the rotation of the cylinder ring opens and closes the feed holes, facilitating desiccant replacement and refilling. The drying components rotate 360°, repositioning the desiccant in the storage cylinder to ensure that the desiccant usage in the storage cylinder is consistent. During replacement and refilling, the desiccant usage is kept to a minimum, avoiding desiccant waste. Attached Figure Description

A cylindrical ring 29 is rotatably installed on the outside of the storage cylinder 25, and a third material hole 30 and a fourth material hole 31 are provided on the cylindrical ring 29. The storage cylinder 25 and the cylindrical ring 29 are connected. The outer side of the cylindrical ring 29 is provided with external teeth 37 via bearing connection.

A drive tooth 36 is installed at the output end of the third motor 35, and the drive tooth 36 meshes with the external teeth 37. The bidirectional pneumatic cylinder 5 drives the first translation plate 6 and the second translation plate 14 to move. The drying assembly 4 located between the first sealing cover 8 and the second sealing cover 15 is in a horizontal state. The drying assembly 4 located between the feeding pipe 11 and the collecting cover 18 rotates to a vertical state under the action of the second motor 24. At this time, the first translation plate 6 drives the first sleeve 7 and the feeding pipe 11 to move downwards, and the second translation plate 14 drives the second sleeve 16 and the collecting cover 18 to move upwards. At this time, the first sealing cover 8 and the second sealing cover 15 cover the...

The fan 10 operates to transport the humid air in the generator set through the air trough 26 to the storage cylinder 25.

The third motor 35 operates to drive the drive gear 36 to rotate, which engages with the meshing external gear 37 to rotate the cylinder ring 29.

Then, the cylinder ring 29 continues to rotate until the first material hole 27 corresponds to the third material hole 30. The material valve 13 is opened, and the desiccant in the material cylinder 12 enters the storage cylinder 25 through the first material hole 27 and the third material hole 30, realizing the automatic filling and replacement of the desiccant. After the first translation plate 6 moves up and the second translation plate 14 moves down, the horizontally set drying component 4 rotates 360° and is used to change the position of the desiccant in the storage cylinder 25. After the desiccant replacement is completed, the vertically set drying component 4 rotates 180° and is set horizontally. During use, the first motor 22 drives the rotating gear 23 to rotate, which cooperates with the meshing gear ring 21 to drive the turntable 2 to rotate on the base 1.This allows for easy interchange of the two drying components 4.

[0034] The working environment inside the generator set is monitored, and the slip rings and carbon brushes are adjusted in real time based on the monitoring data. If the temperature is abnormal and continues to rise too high, an alarm will be triggered to remind maintenance personnel to pay close attention and shut down for maintenance. If the humidity is too high, the dehumidification mechanism will be used to remove moisture to ensure the stable operation of the generator set.

[0035] The rotation of turntable 2 facilitates the interchange of the two drying components 4, enabling them to perform air drying and desiccant replacement and refilling separately. The second motor 24 rotates the drying component 4 180°. The rotation of the cylinder ring 29 opens and closes the material hole, facilitating desiccant replacement and refilling.
