Description

Technical Field

[0001] The intelligent fuse field of the present invention is specifically an intelligent fuse with a remote control function. Background Art

[0002] Smart fuses are widely used in high and low voltage power distribution systems and control systems as well as electrical equipment. As short circuit and overcurrent protectors, they are one of the most commonly used protection devices. The working principle of smart fuses is mainly based on the thermal effect of current and the physical characteristics of thermal expansion of metal conductors. When the circuit is working normally, the heat generated by the current passing through the fuse (usually a metal wire or metal sheet) is balanced with the heat dissipated by the fuse to the surrounding environment. At this time, the fuse remains solid and the circuit is unobstructed. However, once an abnormal situation such as a short circuit or overload occurs in the circuit, the current will increase sharply, far exceeding the rated current value of the fuse. At this time, the heat on the fuse accumulates rapidly and the temperature rises sharply. When the temperature reaches the melting point of the fuse, the fuse begins to melt and form a fracture, thereby cutting off the circuit and achieving the purpose of protecting electrical equipment.

[0003] At present, some existing intelligent fuses cannot be remotely controlled during use, so that when the internal fuse blows due to the protection circuit, it is necessary to operate it in person on site, which requires users to spend time and energy on maintenance and replacement. If it is installed in a high place, every time the fuse blows, the user needs to climb up to the high place to replace it, which increases the danger of user use and increases the cumbersomeness of user use. It is not convenient enough. If the circuit is suddenly connected when replacing the fuse, it will cause electric shock to the user, further increasing the danger of user use. Summary of the invention

[0004] The purpose of the present invention is to provide an intelligent fuse with a remote control function to solve the problem that some of the existing intelligent fuses mentioned in the above background technology cannot be remotely controlled during use, so that after the internal fuse is blown due to the protection circuit, it is necessary to go to the site in person to operate, so that the user needs to spend time and energy to perform maintenance and replacement work. If it is installed at a high place, each time the fuse is blown, the user needs to climb to a high place to replace it, thereby increasing the danger of user use and the cumbersomeness of user use, which is not convenient enough. If the circuit is suddenly connected when replacing the fuse, it will cause the user to get an electric shock, further increasing the danger of user use. Through this solution, the user can remotely control it to automatically cut off the power, automatically access and automatically replace it, which can avoid the user consuming a lot of time and energy to replace the fuse. The device can automatically replace it at any time, further improving the replacement efficiency. At the same time, the device does not require manual replacement work, effectively avoiding the situation where the circuit is connected due to a sudden accident when replacing the fuse, causing the user to get an electric shock, further improving the safety of user use, and providing great convenience for users to replace the fuse.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] After the device is installed in the circuit, the current is transmitted by connecting the conductive sheet and the fuse. When the user needs to maintain the circuit, the user controls the device to cut off the power through the remote terminal. At this time, the second electric push rod is controlled by the remote controller, and the support rod rotates under the action of the first torsion spring's own rebound force. At the same time, the second electric push rod extends and rotates. When the second electric push rod and the support rod are perpendicular to each other, the extended second electric push rod pushes the support rod to rotate around the first fixed rod until one side of the support rod fits with the inside of the connecting block. At this time, both sets of support rods are at the bottom end of the fuse, and then the output end of the first electric push rod is shortened, and the first electric push rod pulls one end of the connecting block to rotate downward. At this time, the connecting block drives the two sets of clamps to When the fuse is in the open position, the connecting block also drives the two sets of support rods to rotate, thereby rotating the fuse piece through the support rods and the clamp. When the two ends of the fuse piece are no longer in contact with the connecting conductive sheet, the circuit is in a disconnected state, thereby further improving the safety of the user in repairing the circuit. If a short circuit occurs in the circuit accidentally, the fuse piece will be disconnected from the fuse slot due to the over-high temperature, thereby disconnecting the entire circuit. At the same time, the remote controller remotely notifies the user that the circuit is short-circuited and the fuse piece has been blown. When the temperature sensor detects that the temperature of the fuse piece is too high, the first electric push rod starts to work, the output end of the first electric push rod shortens, and the output end of the first electric push rod pulls one end of the connecting block downward, and the connecting block drives one end of the clamp upward The chuck and the connecting block perform circular motion. After one end of the chuck stops tightening the fuse, the fuse falls downward under the action of gravity. After the fuse falls, the first electric push rod stops working. At this time, the connecting block and the chuck can be reset under the action of the first spring. At this time, one end of the chuck fits with one end of the connecting conductive sheet. When the fuse falls on the top of the movable cover, the ends of the movable cover that are close to each other rotate downward under the action of the fuse's own gravity, so that the fuse falls into the storage bin for storage. Finally, the movable cover is reset under the action of the second torsion spring, and the movable cover can be limited by two sets of limit plates. When the user has finished overhauling the circuit, the user can remotely control the device to work. The fuse is automatically installed. After the remote controller receives the command, it controls the two sets of third electric push rods to work. The output end of the third electric push rod is shortened. At the same time, the output end of the third electric push rod drives the push plate to move to the side close to the movable seat. When the third electric push rod is shortened to the shortest position, the push plate is also in the position closest to the movable seat. Under the action of the rebound force of the second spring itself, the top plate moves up, and the fuse is pushed upward through the top plate, so that the top group of fuses enters the inside of the push groove, and then the output end of the third electric push rod is extended, so that the push plate drives the fuse to move through the push groove, and at the same time, the push plate drives the two sets of limit slides to move, and the limit slides can be used to limit the fuse inside the storage slot.If the fuse inside the storage slot is used up, the two ends of the top plate will conflict with the pressure sensor, and the user can be reminded through the remote controller. To add a fuse, the user first removes the sealing cover, and then rotates the second threaded rod to remove it. At this time, the user can lift the movable seat, the third electric push rod and the push plate. At this time, the movable seat, the third electric push rod and the push plate perform circular motions, and then the user can store the fuse in the storage tank. At the same time, the fuse can press the second spring through the top plate. The user removes the sealing plate through the screws, so that the broken material inside the storage bin can be taken out. When the device is in use, the user can remotely control it to automatically cut off the power, automatically retrieve and automatically replace it, which can avoid the user consuming a lot of time and energy to replace the fuse. The device can automatically replace it at any time, further improving the replacement efficiency. At the same time, the device does not require manual replacement, effectively avoiding the situation where the circuit is connected due to sudden accidents when replacing the fuse, causing the user to be electrocuted, further improving the safety of the user, and providing great convenience for the user to replace the fuse.

In order to avoid the limit block 17 blocking the second electric push rod 2 0 movement, the first torsion spring 19 is in a compressed state, so that the support rod 16 is conveniently moved away from the limit block 17 through the first torsion spring 19, and the subsequent second electric push rod 20 makes the support rod 16 move, the control ends of the first electric push rod 15, the second electric push rod 20 and the temperature sensor 21 are all electrically connected to the remote controller 14, which is convenient for the operation of the device, and the control ends of the third electric push rod 26 and the pressure sensor 33 are all electrically connected to the remote controller 14, which is convenient for the operation of the device, and the first electric push rod 15 can be extended and retracted under the action of external force when not working, which is convenient for subsequent automatic replacement work and convenient for the movement of the chuck 8, avoiding limiting the movement of the chuck 8 by the first electric push rod 15.

[0032] Working principle: when the user needs to use the device, the user first removes the sealing cover 2, and then rotates the first threaded rod 7 so that one end of the wire clamping plate 6 can be lifted up, and then passes the wire through the wire hole 41, so that one end of the wire is tightly fixed to one end of the connecting conductive sheet 4, and then passes the wire through the wire clamping seat 5 and the wire clamping plate 6, and then rotates the first threaded rod 7 to lock the wire through the wire clamping seat 5 and the wire clamping plate 6 to prevent the wire from falling off due to repeated movement. After the device is installed in the circuit, the current is transmitted through the connecting conductive sheet 4 and the fuse 11. When the user needs to maintain the circuit, the user controls the device to power off through the remote terminal. At this time, the second electric push rod 20 is controlled to work through the remote controller 14, and the second electric push rod 20 The output end is extended, and the support rod 16 rotates under the action of the first torsion spring 19's own resilience. At the same time, the second electric push rod 20 is extended and rotated. When the second electric push rod 20 and the support rod 16 are perpendicular to each other, the extended second electric push rod 20 pushes the support rod 16 to rotate around the first fixed rod 18 until one side of the support rod 16 fits with the inside of the connecting block 9. At this time, both groups of support rods 16 are at the bottom end of the fuse 11, and then the first electric push rod 15 works, and the output end of the first electric push rod 15 is shortened. The output end of the first electric push rod 15 pulls one end of the connecting block 9 to rotate downward. At this time, the connecting block 9 drives the two groups of clamps 8 to rotate, and the connecting block 9 also drives the two groups of support rods 16 to rotate, thereby The chuck 8 drives the fuse 11 to move upward. When the two ends of the fuse 11 are no longer in contact with the connecting conductive sheet 4, the circuit is in a disconnected state, thereby further improving the safety of the user's circuit maintenance. When the user has completed the maintenance, the chuck 8 and the fuse 11 are reset through the first electric push rod 15 and the first spring 10. At this time, the chuck 8 presses the fuse 11 downward again through the first spring 10, and one side of the support rod 16 is in contact with the limit block 17 through the second electric push rod 20. At this time, the first torsion spring 19 is in a compressed state. If a short circuit occurs accidentally in the circuit, the fuse 11 will be disconnected from the position of the fuse slot 12 due to the overhigh temperature, thereby disconnecting the entire circuit and remotely controlling the fuse 11. The program controller 14 remotely notifies the user that the circuit is short-circuited and the fuse 11 has been blown. When the temperature sensor 21 detects that the temperature of the fuse 11 is too high, the first electric push rod 15 starts to work, and the output end of the first electric push rod 15 shortens. The output end of the first electric push rod 15 pulls one end of the connecting block 9 to move downward. At this time, the connecting block 9 drives one end of the clamp 8 to move upward, and the clamp 8 and the connecting block 9 perform a circular motion. After one end of the clamp 8 does not tighten the fuse 11, the fuse 11 falls downward under the action of gravity. After the fuse 11 falls, the first electric push rod 15 does not work. At this time, the connecting block 9 and the clamp 8 can be reset under the action of the first spring 10. At this time, one end of the clamp 8 is in contact with one end of the connecting conductive sheet 4.When the fuse 11 falls on the top of the movable cover plate 36, the end of the movable cover plate 36 close to each other rotates downward under the action of the fuse 11's own gravity, so that the fuse 11 falls into the storage bin 34 for storage. Finally, the movable cover plate 36 is reset under the action of the second torsion spring 38. After resetting, the top of the movable cover plate 36 is respectively fitted with the bottom of the limit plate 39, and the movable cover plate 36 can be limited by the two sets of limit plates 39. When the user has finished overhauling the circuit, the user remotely controls the device to automatically install the fuse 11. After receiving the command, the remote controller 14 controls the two sets of third electric push rods 26 to work through the remote controller 14. The third electric push rods 26 are The output end of the rod 26 is shortened, and at the same time, the output end of the third electric push rod 26 drives the push plate 28 to move toward the side close to the movable seat 24. When the third electric push rod 26 is shortened to the shortest position, the push plate 28 is also in the position closest to the movable seat 24. Under the action of the rebound force of the second spring 32 itself, the top plate 31 moves upward, and the fuse 11 is pushed upward by the top plate 31, so that the top group of fuses 11 enters the interior of the push groove 40, and then the output end of the third electric push rod 26 is extended, so that the push plate 28 drives the fuse 11 to move through the push groove 40, and at the same time, the push plate 28 drives the two groups of limit slides 27 to move, and the limit slides 27 can limit the fuse 11 inside the storage slot 29, so as to avoid The fuse 11 in the storage slot 29 continues to move upward, and the push plate 28 drives the fuse 11 to slide on the top of the connecting plate 3. When one side of the fuse 11 contacts the arc surface at one end of the clamp 8, the end of the clamp 8 with the arc surface moves upward, and the other end of the clamp 8 moves downward. At the same time, the first spring 10 is compressed, and the push plate 28 pushes the fuse 11 between the clamp 8 and the connecting plate 3 until one side of the fuse 11 contacts the limit rod 22. At this time, the output end of the third electric push rod 26 drives the push plate 28 to reset. At this time, the push plate 28 is at the top of the fuse 11 in the storage slot 29, so that the fuse 11 is limited by the push plate 28. At this time, the replacement is completed, and the user can connect the circuit. This device is automatic The fuse 11 can be automatically replaced without the user directly touching the fuse 11, which can effectively avoid the situation where the circuit is connected due to an accident when the user replaces the fuse 11, causing the user to be electrocuted, thereby further improving the safety of the user. If the fuse 11 in the storage slot 29 is used up, the two ends of the top plate 31 will conflict with the pressure sensor 33, and the remote controller 14 can remind the user to add the fuse 11, thereby ensuring the normal replacement of the fuse 11. The user first removes the sealing cover 2, and then rotates the second threaded rod 25 to remove it. At this time, the user can lift the movable seat 24, the third electric push rod 26 and the push plate 28. At this time, the movable seat 24, the third electric push rod 26 and the push plate 28 perform a circular motion.Then the user can store the fuse 11 inside the storage slot 29. At the same time, the fuse 11 can press the second spring 32 through the top plate 31. The user removes the sealing plate 35 through the screws, so that the broken material inside the storage bin 34 can be taken out. When the device is in use, the user can remotely control it to automatically cut off the power, automatically retrieve and automatically replace it, which can avoid the user consuming a lot of time and energy to replace the fuse 11. The device can automatically replace it at any time, further improving the replacement efficiency. At the same time, the device does not require manual replacement, effectively avoiding the situation where the circuit is connected due to a sudden accident when replacing the fuse 11, causing the user to be electrocuted, further improving the safety of the user, and providing great convenience for the user to replace the fuse 11.
