Description

Technical Field

[0001] The present invention relates to the technical field of power transmission and distribution equipment in power systems, and more particularly to a safety clutch device for high-voltage electrical appliances. Background Art

[0002] The safety clutch device is used in high-voltage electrical switchgear as a safety protection device for the isolating switch operating mechanism. Common safety clutch devices are mainly composed of servo motors, transmission rods, limit mechanisms, and control systems. The specific process of the safety clutch device for high-voltage electrical switch is as follows: the servo motor inputs a stable working current under the action of the control system, generates a certain torque, and transmits it to the rotary switch through the transmission rod and limit mechanism, thereby driving the clutch switch to open and close;

[0003] During actual operation, we found that some safety clutch devices could not work properly and could not switch circuits accurately and quickly. In the later research process, we found that the main reason for the above situation was that the connection between the transmission rod and the limit mechanism was damaged and broken. The main factor for this situation was excessive aging and wear between the transmission rod and the limit mechanism. When this phenomenon occurred, it was mainly discovered through manual quality inspection, resulting in irreversible damage to the high-voltage electrical appliances. In severe cases, it may cause irreversible damage to the entire power system, resulting in certain economic losses.

[0004] Therefore, we are in urgent need of a safety clutch device for high-voltage electrical appliances to solve the technical problems raised above. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a safety clutch device for high-voltage electrical appliances to solve the problems existing in the above-mentioned background technology.

[0006] The present invention provides the following technical solution: a safety clutch device for high-voltage electrical appliances, comprising:

[0007] Power equipment, wherein a cabinet door is installed on the inner wall of the front end of the power equipment to protect the components installed inside the power equipment;

[0008] An electric control mechanism, used to control the transmission of electric power to the electric equipment, wherein the electric control mechanism is installed on the inner side of the bottom of the electric equipment;

[0009] A protective shell is installed on the inner wall of the bottom of the cabinet door, and an early warning system is also provided inside the power equipment to monitor whether the electric control mechanism can normally control the transmission of relevant power.

[0010] Furthermore, a rotary switch is installed in the middle area of the front end of the electric control mechanism, and a transmission rod is fixedly installed in the middle area of the front end of the rotary switch. When the transmission rod rotates, it can drive the rotary switch to operate synchronously, thereby controlling the electric control mechanism to transmit corresponding power. A slot is opened in the middle area of the inner wall of the front end of the transmission rod, and a limit plate is installed on the outer side of the transmission rod near the slot.

[0011] A servo motor is installed on the inner wall of one side of the protective shell.

[0012] Furthermore, a first transmission gear is installed at the output end of the servo motor, and the outer wall of the first transmission gear is meshedly connected with a second transmission gear. A gear transmission group can be formed between the first transmission gear and the second transmission gear to transmit the rotational force generated by the servo motor.

[0013] Furthermore, an auxiliary transmission rod is installed through the middle position of the second transmission gear, and the ends of both ends of the auxiliary transmission rod extend to the external space of the second transmission gear. A main transmission rod is fixedly installed at one end of the auxiliary transmission rod, and two groups of placement grooves are respectively provided at symmetrical positions of the inner wall of the main transmission rod away from one end of the auxiliary transmission rod. The two groups of placement grooves are respectively located on both sides of the axis of the main transmission rod and are symmetrical about the axis, and a conveying cabin is provided on the inner wall of the main transmission rod near the two groups of placement grooves to ensure that air is circulated between the two groups of placement grooves. The inner walls of the two groups of placement grooves are both sleeved with hollow plates, and the middle position of the spring passes through the interior of the conveying cabin. An air pressure sensing device is installed on the inner wall of the conveying cabin for sensing pressure data of the two groups of placement grooves and the interior of the conveying cabin, and transmitting it to the early warning system for monitoring the real-time working status of the electronic control mechanism. A rubber layer is installed on the outer side of the hollow plate.

[0014] Furthermore, an air pump is installed on the inner wall of the other side of the protective shell, and a U-shaped delivery pipe is installed at the gas output end of the air pump. A three-way pipe is movably connected to the end of the U-shaped delivery pipe away from the air pump, and an annular plate is fixedly installed on the outer side of the main transmission rod near the auxiliary transmission rod position, and an annular air cabin is provided on the inner wall of the main transmission rod near the annular plate position. The three-way pipe has two groups of air outlets at the end away from the U-shaped delivery pipe, one group of air outlets of the three-way pipe is arranged inside the annular air cabin, and the other group of air outlets of the three-way pipe is arranged inside the delivery cabin. The air pump inputs a stable working current to generate compressed air, and delivers it to the interior of the delivery cabin through the U-shaped delivery pipe and the other group of air outlets of the three-way pipe, thereby driving the two groups of hollow plates to move toward the external space of the main transmission rod. After the hollow plate moves to the specified position, the rubber layer and the outer wall of the hollow plate are adapted to the inner wall of the slot.

[0015] Furthermore, the inner walls at both ends of the annular plate are provided with limiting grooves, and the inner walls of the annular plate near the limiting grooves are installed with torsion spring devices, the output end of the torsion spring device is installed with an auxiliary support rod, the end of the auxiliary support rod away from the torsion spring device is installed with a limiting support plate, the side of the limiting support plate away from the position of the annular plate is installed with a telescopic tube, and the end of the telescopic tube away from the position of the limiting support plate is installed inside the annular air chamber.

[0016] Furthermore, the air pump inputs a stable working current to generate compressed air or adsorbed air, which is input into the interior of the annular air cabin through a group of air outlets of the U-shaped delivery pipe and the three-way pipe. The compressed air inside the annular air cabin is transmitted to the telescopic tube to drive the telescopic tube to be in a stretched state. Under the drive of the torsion spring device, the two groups of limit support plates are controlled to be attached to the outer walls of the two groups of limit plates. The adsorbed air inside the annular air cabin is transmitted to the telescopic tube to drive the telescopic tube to be in a contracted state, and the limit support plates are controlled to return to their original positions.

[0017] Furthermore, the early warning system simulates the simulated pressure data generated by the air pressure sensing device when the hollow plate and the card slot are in normal working state, and integrates the simulated pressure data to form a threshold range. The early warning system compares the real-time pressure data with the threshold range. When the real-time pressure data is not within the threshold range, it is determined that wear and aging occurs between the hollow plate and the card slot.

[0018] Technical effects and advantages of the present invention:

[0019] 1. This invention uses an early warning system to simulate the pressure data generated by the air pressure sensing device when the hollow plate and the slot are in normal operation. This data is then integrated to form a threshold range. The early warning system then compares the real-time pressure data with the threshold range. If the real-time pressure data is outside the threshold range, it determines that wear and aging are occurring between the hollow plate and the slot, thereby achieving real-time monitoring of the working status of the hollow plate and the slot.

[0020] 2. This invention uses an air pump to input a stable reverse operating current, generating an adsorption force. This current is then delivered to the interior of the transport cabin through the U-shaped transport pipe and the other set of air outlets in the tee, thereby driving the two sets of hollow plates to return to their original positions. After the two sets of hollow plates return to their original positions, the main drive rod and the inner wall of the slot are in a non-contact state. This prevents friction between the inner wall of the slot and the main drive rod and the outer walls of the hollow plates caused by vibrations generated by the operation of the electrical equipment. This further reduces the efficiency of the hollow plates and main drive rod, thereby extending their service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] A protective shell 3 is installed on the inner wall of the bottom of the cabinet door 101. An early warning system is also provided inside the power equipment 1 to monitor whether the electric control mechanism 2 can normally control the transmission of relevant power.

[0034] In the embodiment of the present application, the specific workflow of this part of the application embodiment is: during work, the staff can manually open the cabinet door 101 to facilitate the inspection and maintenance of some components inside the power equipment 1.

[0035] Reference Figures 1 to 2 As shown, the present invention provides a safety clutch device for high-voltage electrical appliances, wherein a rotary switch 201 is installed in the middle area of the front end of the electric control mechanism 2, and a transmission rod 202 is fixedly installed in the middle area of the front end of the rotary switch 201. When the transmission rod 202 rotates, it can drive the rotary switch 201 to operate synchronously, thereby controlling the electric control mechanism 2 to perform corresponding power transmission. A slot 203 is provided in the middle area of the inner wall of the front end of the transmission rod 202, and a limit plate 204 is installed on the outer side of the transmission rod 202 near the slot 203.

[0036] In the embodiment of the present application, the specific working process of this part of the application embodiment is: the external rotational force is transmitted to the transmission rod 202, thereby driving the transmission rod 202 and the rotary switch 201 to perform synchronous rotation operations, and then controlling the electric control mechanism 2 to perform corresponding power transmission.

[0037] Reference Figures 1 to 6 As shown, the present invention provides a safety clutch device for high-voltage electrical appliances. A servo motor 302 is mounted on the inner wall of one side of the protective housing 3. A first transmission gear 303 is mounted on the output end of the servo motor 302. A second transmission gear 304 is meshedly connected to the outer wall of the first transmission gear 303. A gear transmission group can be formed between the first transmission gear 303 and the second transmission gear 304 for transmitting the rotational force generated by the servo motor 302.

[0038] The middle position of the second transmission gear 304 is penetrated by an auxiliary transmission rod 305. The ends of the auxiliary transmission rod 305 extend to the external space of the second transmission gear 304. One end of the auxiliary transmission rod 305 is fixedly installed with the main transmission rod 301. The main transmission rod 301 is symmetrically provided with two groups of placement grooves at positions away from the inner wall of one end of the auxiliary transmission rod 305. The two groups of placement grooves are located on both sides of the axis of the main transmission rod 301 and are symmetrical about the axis. The inner wall of the main transmission rod 301 is close to the two groups of placement grooves. A conveying cabin 312 is provided at the location of the placement slots to ensure air circulation between the two groups of placement slots. Hollow plates 308 are sleeved on the inner walls of the two groups of placement slots, and the middle position of the spring 313 passes through the interior of the conveying cabin 312. An air pressure sensing device is installed on the inner wall of the conveying cabin 312 to sense the pressure data of the two groups of placement slots and the interior of the conveying cabin 312, and transmit it to the early warning system for monitoring the real-time working status of the electric control mechanism 2. A rubber layer 309 is installed on the outer side of the hollow plate 308;

[0039] An air pump 307 is installed on the inner wall of the other side of the protective shell 3, and a U-shaped delivery pipe 306 is installed on the gas output end of the air pump 307. A tee pipe 311 is movably connected to the end of the U-shaped delivery pipe 306 away from the air pump 307. An annular plate 4 is fixedly installed on the outer side of the main transmission rod 301 near the auxiliary transmission rod 305, and an annular air chamber 310 is provided on the inner wall of the main transmission rod 301 near the annular plate 4. The end of the tee pipe 311 away from the U-shaped delivery pipe 306 has two sets of air outlets, one set of the outlets of the tee pipe 311. The air inlet is arranged inside the annular air cabin 310, and another set of air outlets of the tee pipe 311 is arranged inside the conveying cabin 312. The air pump 307 inputs a stable working current to generate compressed air, and transports the compressed air to the inside of the conveying cabin 312 through the U-shaped conveying pipe 306 and another set of air outlets of the tee pipe 311, thereby driving the two sets of hollow plates 308 to move toward the external space of the main transmission rod 301. After the hollow plates 308 move to the designated position, the outer walls of the rubber layer 309 and the hollow plates 308 are adapted to the inner walls of the card slot 203.

[0040] In the embodiment of the present application, when the compressed air is transmitted to the interior of the hollow plate 308 , the rubber layer 309 is in an expanded state, so that the early warning system can monitor the working state of the electronic control mechanism 2 in real time.

[0041] The specific workflow of this application example is as follows:

[0042] The air pump 307 inputs a stable working current to generate compressed air, which is delivered to the interior of the delivery cabin 312 through the U-shaped delivery pipe 306 and another set of air outlets of the tee pipe 311, thereby driving the two sets of hollow plates 308 to move toward the external space of the main transmission rod 301. After the hollow plates 308 move to the designated position, the rubber layer 309, the hollow plates 308 and the main transmission rod 301 are snapped into the inner wall of the slot 203. At the same time, the servo motor 302 inputs a stable working current and drives the auxiliary transmission rod 305, the main transmission rod 301, the hollow plates 308, the transmission rod 202 and the rotary switch 201 to rotate synchronously through the transmission of the first transmission gear 303 and the second transmission gear 304, so as to control the power transmission direction of the electronic control mechanism 2.

[0043] After the power transmission direction of the electronic control mechanism 2 is adjusted, the air pump 307 inputs a stable reverse working current to generate an adsorption force, and transmits the current to the interior of the conveying cabin 312 through the U-shaped conveying pipe 306 and another set of air outlets of the three-way pipe 311, thereby driving the two sets of hollow plates 308 to return to their original positions. After the two sets of hollow plates 308 return to their original positions, the main transmission rod 301 and the inner wall of the card slot 203 are in a non-contact state, avoiding the vibration force generated by the power equipment 1 during operation, thereby causing friction between the inner wall of the card slot 203 and the outer wall of the main transmission rod 301 and the hollow plate 308, further reducing the efficiency of the loss of the hollow plate 308 and the main transmission rod 301, thereby enhancing the service life of the hollow plate 308 and the main transmission rod 301.

[0044] Reference Figures 4 to 7 As shown, the present invention provides a safety clutch device for high-voltage electrical appliances. Limiting grooves 401 are formed on the inner walls of both ends of the annular plate 4, and torsion spring devices 404 are installed on the inner walls of the annular plate 4 near the limiting grooves 401. An auxiliary support rod is installed at the output end of the torsion spring device 404. A limiting support plate 402 is installed at the end of the auxiliary support rod away from the torsion spring device 404. A telescopic tube 403 is installed on the side of the limiting support plate 402 away from the annular plate 4. The end of the telescopic tube 403 away from the limiting support plate 402 is installed inside the annular air chamber 310.

[0045] The air pump 307 inputs a stable working current to generate compressed air or adsorbed air, which is input into the interior of the annular air cabin 310 through a group of air outlets of the U-shaped delivery pipe 306 and the three-way pipe 311. The compressed air inside the annular air cabin 310 is transmitted to the telescopic tube 403 to drive the telescopic tube 403 to be in a stretched state. Under the drive of the torsion spring device 404, the two groups of limit support plates 402 are controlled to be attached to the outer walls of the two groups of limit plates 204. The adsorbed air inside the annular air cabin 310 is transmitted to the telescopic tube 403 to drive the telescopic tube 403 to be in a contracted state, and the limit support plate 402 is controlled to return to its original position.

[0046] In an embodiment of the present application, when the two groups of the limiting support plates 402 are respectively attached to the outer walls of the corresponding limiting plates 204, the two groups of limiting support plates 402 are symmetrically placed with respect to the center point of the transmission rod 202, and are used for the two groups of limiting support plates 402 to control the limiting plates 204 and the transmission rod 202 to rotate clockwise and counterclockwise.

[0047] The specific working process of the embodiment of this part of the application is as follows: when the early warning system determines that there is wear at the connection between the hollow plate 308 and the slot 203, which causes the electric control mechanism 2 to be unable to work, the air pump 307 inputs a stable working current to generate compressed air, which is input into the interior of the annular air cabin 310 through a group of air outlets of the U-shaped delivery pipe 306 and the three-way pipe 311. The compressed air inside the annular air cabin 310 is transmitted to the telescopic tube 403 to drive the telescopic tube 403 to be in a stretched state. Under the drive of the torsion spring device 404, the two groups of limit support plates 402 are controlled to be attached to the outer walls of the two groups of limit plates 204, thereby assisting in controlling the rotary switch 201 to perform normal rotation adjustment, thereby achieving the effect of temporarily assisting the electric control mechanism 2 to perform normal power adjustment operations, and avoiding the phenomenon of the electric control mechanism 2 not being able to work normally.

[0048] Reference Figures 1 to 7 As shown, the present invention provides a safety clutch device for high-voltage electrical appliances. The early warning system simulates the simulated pressure data generated by the air pressure sensing device when the hollow plate 308 and the card slot 203 are in normal working state, and integrates the simulated pressure data to form a threshold range. The early warning system compares the real-time pressure data with the threshold range. When the real-time pressure data is not within the threshold range, it is determined that wear and aging occurs between the hollow plate 308 and the card slot 203.

[0049] In the embodiment of the present application, when the early warning system determines that wear and aging occurs between the hollow plate 308 and the card slot 203, it determines that the electric control mechanism 2 cannot work normally at this time, and remotely sends an early warning message to the staff to remind them to go to the site for inspection.

[0050] The specific workflow of this application is as follows:

[0051] Equipment maintenance: During operation, the staff can manually open the cabinet door 101 to facilitate maintenance of some components inside the power equipment 1;

[0052] Circuit adjustment process of the electronic control mechanism 2: the air pump 307 inputs a stable working current to generate compressed air, and delivers the compressed air to the interior of the delivery cabin 312 through the U-shaped delivery pipe 306 and another set of air outlets of the tee pipe 311, thereby driving the two sets of hollow plates 308 to move toward the external space of the main transmission rod 301. After the hollow plates 308 move to the designated position, the rubber layer 309, the hollow plates 308 and the main transmission rod 301 are snapped into the inner wall of the slot 203. At the same time, the servo motor 302 inputs a stable working current and drives the auxiliary transmission rod 305, the main transmission rod 301, the hollow plates 308, the transmission rod 202 and the rotary switch 201 to rotate synchronously through the transmission of the first transmission gear 303 and the second transmission gear 304, so as to control the power transmission direction of the electronic control mechanism 2;

[0053] After the power transmission direction of the electric control mechanism 2 is adjusted, the air pump 307 inputs a stable reverse working current to generate an adsorption force, and transmits the air to the interior of the transmission cabin 312 through the U-shaped transmission pipe 306 and the other set of air outlets of the three-way pipe 311, thereby driving the two sets of hollow plates 308 to return to their original positions. After the two sets of hollow plates 308 return to their original positions, the main transmission rod 301 and the inner wall of the card slot 203 are in a non-contact state, avoiding the vibration force generated by the power equipment 1 during operation, thereby avoiding the friction between the inner wall of the card slot 203 and the outer wall of the main transmission rod 301 and the hollow plate 308, further reducing the efficiency of the loss of the hollow plate 308 and the main transmission rod 301, thereby enhancing the service life of the hollow plate 308 and the main transmission rod 301;

[0054] Temporary processing flow: When the early warning system determines that the connection between the hollow plate 308 and the card slot 203 is worn, and thus the electric control mechanism 2 cannot work, the air pump 307 inputs a stable working current to generate compressed air, which is input into the interior of the annular air cabin 310 through a set of air outlets of the U-shaped delivery pipe 306 and the three-way pipe 311. The compressed air inside the annular air cabin 310 is transmitted to the telescopic tube 403 to drive the telescopic tube 403 to be in a stretched state. Under the drive of the torsion spring device 404, the two groups of limit support plates 402 are controlled to be attached to the outer walls of the two groups of limit plates 204, thereby assisting in controlling the rotary switch 201 to perform normal rotation adjustment, thereby achieving the effect of temporarily assisting the electric control mechanism 2 to perform normal power adjustment operations, and avoiding the phenomenon of the electric control mechanism 2 not being able to work normally.

A safety clutch device for high-voltage electrical appliances according to claim 2, characterized in that: The inner walls of both ends of the annular plate (4) are provided with limiting grooves (401), and the inner walls of the annular plate (4) near the limiting grooves (401) are both installed with torsion spring devices (404), the output end of the torsion spring device (404) is installed with an auxiliary support rod, and the end of the auxiliary support rod away from the torsion spring device (404) is installed with a limiting support plate (402), and a telescopic tube (403) is installed on the side of the limiting support plate (402) away from the annular plate (4), and the end of the telescopic tube (403) away from the limiting support plate (402) is installed inside the annular air chamber (310).

4. A safety clutch device for high-voltage electrical appliances according to claim 3, characterized in that: The air pump (307) inputs a stable working current to generate compressed air or adsorbed air, which is input into the interior of the annular air chamber (310) through a group of air outlets of the U-shaped delivery pipe (306) and the three-way pipe (311). The compressed air in the annular air chamber (310) is transmitted to the telescopic tube (403), driving the telescopic tube (403) to be in a stretched state. Under the drive of the torsion spring device (404), the two groups of limit support plates (402) are controlled to be attached to the outer walls of the two groups of limit plates (204). The adsorbed air in the annular air chamber (310) is transmitted to the telescopic tube (403), driving the telescopic tube (403) to be in a contracted state, and controlling the limit support plates (402) to return to their original positions.

5. The safety clutch device for high-voltage electrical appliances according to claim 1, characterized in that: The early warning system simulates the simulated pressure data generated by the air pressure sensing device when the hollow plate (308) and the card slot (203) are in a normal working state, and integrates the simulated pressure data to form a threshold range. The early warning system compares the real-time pressure data with the threshold range. When the real-time pressure data is not within the threshold range, it is determined that wear and aging occurs between the hollow plate (308) and the card slot (203).
