Description

Technical Field

[0001] The utility model relates to the technical field of power distribution switch auxiliary equipment, in particular to a remote control device for a power distribution switch. Background Art

[0002] The distribution switch is a very important electrical appliance installed in the power system. Taking the circuit breaker as an example, it integrates multiple protection functions in one. In addition to contacting and disconnecting the circuit, it can also protect the circuit or electrical equipment from short circuit, severe overload and undervoltage. The existing distribution switch will automatically disconnect when a short circuit and severe overload occur, but it often requires manual closing after the fault is eliminated. Moreover, the distribution switch is generally installed on strong electricity. For some timid people, closing the switch can easily cause psychological pressure. On the other hand, the distribution switch will only actively disconnect the circuit when a circuit fails. When some dangerous situations occur, such as a fire, the user needs to cut off the power supply in time. If the user is not at home at this time, or the passage to the distribution switch is blocked, it will be difficult to close the distribution switch in time, causing certain hidden dangers.

[0003] To solve the above problems, the utility model with announcement number CN214152820U discloses an electrical engineering power distribution switch device, including a switch body and a remote control mechanism, wherein the switch body is provided with a switch paddle, and connected to a closing mechanism inside the switch body; the remote control mechanism includes a power supply device, a drive motor, a controller connected to the drive motor, a WiFi module connected to the controller, a reducer connected to the output shaft of the drive motor, and a dial connected to the output shaft of the reducer, wherein a convex shaft is eccentrically provided on the dial, and a lever is sleeved on the switch paddle, wherein the lever cooperates with the convex shaft, and drives the lever to move up and down when the dial rotates. The utility model can remotely open and close the circuit, providing better protection for users to use electricity safely.

[0004] However, in actual operation, the force on the operating handle of the distribution switch (taking a circuit breaker as an example) is nonlinear at the moment of closing and opening. Taking closing as an example, when the operating handle is pushed to half of the stroke (the operating handle rotates), the second half of the stroke is automatically attracted, and its rotation speed is much greater than the rotation speed of the first half. The components in the operating mechanism in the above-mentioned utility model are all rigid structures. Therefore, the above-mentioned utility model has the following defects: First, the switch paddle will hit the lever in the second half of the stroke; second, the lever itself has a limiting effect on the switch paddle. After the switch paddle is closed, the distribution switch can work normally, but the distribution switch will also automatically disconnect during normal operation. At this time, the lever still has a limiting effect on the switch paddle, which will seriously affect the disconnection action of the switch paddle and pose a safety risk. Utility Model Content

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0029] Reference Figure 1-6 The utility model is a remote control device for a power distribution switch, including an operating mechanism, which includes a traction rope 2, a traction rod 3, an electric control box 5, and an electric cylinder 6. The traction rod 3 is movably arranged on an operating handle 16 of a circuit breaker 15. Both ends of the traction rope 2 are connected to the traction rod 3, and the middle part of the traction rope 2 is connected to the working end of the electric cylinder 6. The electric cylinder 6 drives the traction rope 2 and the traction rod 3 to rotate the operating handle 16 upward.

[0030] A wireless transmission module and a controller are arranged inside the electric control box 5 , and the controller is electrically connected to the electric cylinder 6 and the wireless transmission module.

[0031] The wireless transmission module can use at least one of a Bluetooth module, a WiFi module, and a 5G network module to establish a network connection with a remote mobile client or an operating console.

[0032] The controller sends and receives operation instruction information through the wireless transmission module, and controls the action of the electric cylinder according to the operation instruction information.

[0033] The operating handle 16 is provided with a traction through hole, and the traction rod 3 is movably inserted into the traction through hole and is rotatably connected to the operating handle 16 .

[0034] The two ends of the traction rope 2 are fixedly connected to the two ends of the traction rod 3. When the electric cylinder 6 extends (or retracts), it drives the operating handle 16 to rotate from bottom to top. When the operating handle 16 is automatically closed in the second half, the traction rope 2 does not affect the instantaneous automatic action of the operating handle 16, and the traction rope 2 and the traction rod 3 will not be separated from the operating handle 16 when the operating handle 16 is instantly moved.

[0035] The working stroke of the electric cylinder 6 is set. When the electric cylinder 6 reaches the working stroke, the rotation stroke of the operating handle 16 just exceeds half, and then the automatic closing action begins, and the electric cylinder 6 is reset at the same time.

[0036] After the electric cylinder 6 is reset, the traction rope 2 between the operating handle 16 and the electric cylinder 6 also returns to a relaxed state. When the circuit breaker 15 automatically disconnects, the operating handle 16 can automatically rotate downward to the disconnecting position, and the traction rope 2 does not affect its disconnecting action.

[0037] The operating mechanism further comprises two first pulley blocks 4, the electric cylinder 6 is located between the two first pulley blocks 4, the first pulley block 4 comprises two vertically arranged pulleys, and the traction rope 2 passes between the grooves of the two vertically arranged pulleys.

[0038] The function of the first pulley block 4 is to change the force direction of the traction rope 2, so that when the electric cylinder 6 moves in the horizontal direction, the operating handle 16 can be driven to rotate upward through the traction rod 3, which is convenient for adjusting the position and direction of the electric cylinder 6 and making the layout of the operating mechanism more reasonable.

[0039] The operating mechanism also includes a rope rack 9, the working end of the electric cylinder 6 is connected to the middle of the rope rack 9, and the second pulley group 10 is installed at both ends of the rope rack 9. The second pulley group 10 includes two laterally arranged pulleys, and the middle part of the traction rope 2 passes between the grooves of the two laterally arranged pulleys.

[0040] The middle part of the traction rope 2 is wound between the two second pulley blocks 10 , and the working end of the electric cylinder 6 drives the second pulley block 10 and the traction rope 2 to move through the rope rack 9 .

[0041] The second pulley block 10 is aligned with the first pulley block 4 so that the traction rope 2 enters the second pulley block 10 in a horizontal direction after being wound from the first pulley block 4, and the portion of the traction rope 2 between the two second pulley blocks 10 is also horizontal.

[0042] The function of the rope rack 9 is to cooperate with the first pulley block 4 so that the traction rope 2 is mainly subjected to force in the horizontal direction between the first pulley block 4 and the second pulley block 10, thereby reducing the deflection between the traction rope 2 and the grooves of the first pulley block 4 and the second pulley block 10.

[0043] The first pulley block 4 and the second pulley block 10 both have two pulleys, and the grooves of the two pulleys are aligned. At the same time, the side walls of the two pulleys are in contact with each other, which can effectively prevent the traction rope 2 from popping out of the groove of the pulley when the operating handle 16 is instantly moved, thereby improving the stability of the operation of the device.

[0044] A guide rail 11 is provided below the rope rack 9 , and a slider 14 is provided inside the guide rail 11 to slide along the extension and contraction direction of the electric cylinder 6 , and the top of the slider 14 is connected to the rope rack 9 .

[0045] The guide rail 11 cooperates with the slider 14 to form a sliding support and guiding function for the rope rack 9.

[0046] When the electric cylinder 6 drives the rope rack 9 to move, the rope rack 9 is slidably connected to the guide rail 11, so that the rope rack 9 moves along the extension and contraction direction of the electric cylinder 6, thereby preventing the rope rack 9 from deflecting.

[0047] An elastic member 12 is provided between the electric cylinder 6 and the rope rack 9 . An elastic member groove 13 is provided on one end of the rope rack 9 close to the electric cylinder 6 . One end of the elastic member 12 is connected to the elastic member groove 13 , and the other end is connected to the working end of the electric cylinder 6 .

[0048] The elastic part 12 can be a spring or a compression spring, or other elastic parts. When the electric cylinder 6 is extended or retracted, the elastic part 12 is elastically deformed, and the mechanical energy of the electric cylinder 6 is converted into the elastic potential energy of the elastic part 12. The mechanical force of the electric cylinder 6 acts on the elastic part 12, and the elastic part 12 is elastically deformed, and then the force is transmitted to the rope rack 9, which drives the traction rope 2 through the rope rack 9, and further drives the traction rod 3 and the operating handle 16 to rotate.

[0049] When the operating handle 16 rotates more than half of the stroke, the operating handle 16 automatically closes, and the tension on the traction rope 2, the rope rack 9, and the second pulley group 10 is instantly reduced, but it will continue to move due to inertia. When the rope rack 9 continues to move, the elastic member 12 returns to its original state. The process of the elastic member 12 returning to its original state corresponds to the process of the rope rack 9 moving, thereby achieving a buffering effect, reducing the instantaneous pulling of the rope rack 9 on the electric cylinder 6 due to inertia, and reducing the risk of damage to the rope rack 9 and the electric cylinder 6.

[0050] The operating mechanism also includes a power box 8 , which is internally provided with a power adapter and a battery. The battery is electrically connected to the electric control box 5 to supply power to the wireless transmission module, the controller, and the electric cylinder 6 .

[0051] Connect to the power grid through a power adapter, which converts AC power into DC power for charging the battery, with a voltage of 5V.

[0052] The battery supplies power to the wireless transmission module, the controller and the electric cylinder 6.

[0053] The device further comprises a housing 1 , an operating mechanism is installed inside the housing 1 , a rope through hole 101 is provided on the side wall of the housing 1 , and a traction rope 2 passes through the rope through hole 101 and is connected to the electric cylinder 6 .

[0054] A base 7 is installed at the bottom of the electric cylinder 6 , and the electric cylinder 6 is fixedly installed on the inner bottom of the housing 1 through the base 7 .

[0055] The device is fixedly connected between the housing 1 and the circuit breaker 15, which reduces the exposure of components in the operating mechanism and further improves safety.

[0056] The rope through hole 101 is aligned with the slide groove of the first pulley block 4 . After the traction rope 2 passes through the rope through hole 101 , it is introduced into the slide groove of the first pulley block 4 and then passes around the second pulley block 10 .

[0057] Mounting plates 102 are provided at both ends of the housing 1 , and the housing 1 is suspended on the top of the circuit breaker 15 through the mounting plates 102 .

[0058] Screw holes are processed on the mounting plate 102, and the mounting plate 102 is fixedly mounted on the tops of both ends of the housing of the circuit breaker 15 by means of bolts.

[0059] Since the connection terminals of a circuit breaker type power distribution switch are generally located at the top and bottom of the circuit breaker, the suspended housing 1 allows a distance to be maintained between the housing 1 and the top of the circuit breaker 15 to avoid affecting the normal connection of the circuit breaker 15 .

[0060] The mounting plate 102 is provided with a cable slot 103 for passing electrical wires.

[0061] The wiring on the top of the circuit breaker 15 can be passed through from the front and back, or from the left and right through the cable groove 103. Passing through from the back and from the left and right better meets the installation environment requirements of the circuit breaker 15 in the distribution cabinet.

[0062] The positional relationship between the electric cylinder 6 and the rope rack 9 in the present application is not unique. The electric cylinder 6 can push the rope rack 9 or pull the rope rack 9 to further drive the traction rope 2. The drawings in the specification take pushing the rope rack 9 as an example.

[0063] Working principle: When in use, the device is fixedly mounted on the circuit breaker 15, and the traction rod 3 is inserted into the operating handle 16.

[0064] When the fault is eliminated and the circuit breaker 15 needs to be closed, a signal is sent to the wireless transmission module through the mobile client or the remote operating console, and the controller controls the electric cylinder 6 to extend, driving the rope rack 9 and the second pulley group 10 to move, and further driving the traction rope 2 to pull the traction rod 3 and the operating handle 16 upward.

[0065] When the operating handle 16 exceeds half of the stroke, it is automatically closed and the electric cylinder 6 returns to the initial position without affecting the automatic disconnection of the circuit breaker 15.

[0066] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
