Description
Technical Field
[0001] The invention relates to the technical field of power equipment maintenance, in particular to a live disconnection and drainage line anti-dropping device for overhead power distribution lines. Background Art
[0002] With the rapid development of social economy and the increasing dependence of people on electricity, the stability and reliability of power supply have become the focus of social attention. However, traditional power maintenance methods usually require planned power outages, which means that users will not be able to use power services during the maintenance period. This power outage not only brings great inconvenience to users' daily life and work. In addition, the arrangement of planned power outages often requires advance notice to users, which increases the complexity of scheduling and management. Due to the complex distribution network environment and frequent equipment vulnerabilities and failures, traditional maintenance methods cannot respond to sudden failures in a timely manner. This delay not only affects the reliability of power supply, but also may cause power outages on a larger scale, thus affecting the normal operation of society. Traditional maintenance methods rely on manual operation, which is inefficient and time-consuming. When replacing equipment, maintenance personnel often need to conduct multiple on-site surveys and equipment inspections, which not only increases labor costs, but also prolongs maintenance time, thereby affecting the flexibility of power supply. In addition, traditional technologies also have shortcomings in safety. In the case of live work, operators face higher safety risks, especially when working at high altitudes or in complex environments, where safety hazards are more prominent. In this case, the limitations of traditional maintenance methods make it difficult to effectively implement safety measures for power workers. Summary of the invention

Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0025] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.
[0026] Example 1
[0027] Reference Figure 1 to Figure 5 , is an embodiment of the present invention, which provides a device for preventing the disconnection of the live disconnection lead wire of the distribution overhead line, which can fix the disconnected wire ends when the distribution overhead line short-circuits the lead wire without power outage, thereby improving the safety of the operation.
[0028] Specifically, the operating unit 100 includes a clamping component 101, linkage components 102 disposed on both sides of the clamping component 101, and an insulating component 103 disposed outside the linkage component 102;
[0029] The power unit 200 includes a power assembly 201 disposed inside the insulating assembly 103 , a transmission assembly 202 disposed at one end of the power assembly 201 , and a transmission assembly 203 disposed between the transmission assembly 202 and the clamping assembly 101 .
[0030] Furthermore, the connection assembly includes a clamping assembly 101 including an insulating wire clamp 101a, and a support frame 101b fixedly connected to the insulating wire clamp 101a.
[0031] Furthermore, the linkage assembly 102 includes a linkage rod 102a hinged to the support frame 101b, a push rod 102b hinged to one end of the support frame 101b, and a limit rod 102c hinged to the push rod 102b.
[0032] Furthermore, the insulating assembly 103 includes an insulating connection sleeve 103a hinged to the limiting rod 102c, an insulating limiting groove 103b opened on one side of the insulating connection sleeve 103a, and an insulating rod 103c fixedly connected to the insulating connection sleeve 103a.
[0033] It should be noted that the insulating rods 103c may be provided with two groups, such as Figure 5 As shown, the connection is made via a cross insulating rod connector.
[0034] Furthermore, the power assembly 201 includes a motor 201a disposed inside the insulating connecting sleeve 103a, and a control button 201b fixedly connected to the motor 201a.
[0035] It should be noted that the motor 201a is a motor 201a that can be controlled to rotate forward and reverse, such as a stepping motor 201a, and the tightening and loosening of the insulating wire clamp 101a is achieved through the forward and reverse rotation of the motor 201a.
[0036] Furthermore, the transmission assembly 202 includes a threaded rod 202a fixedly connected to the motor 201a, and a long nut 202b threadedly connected to the threaded rod 202a.
[0037] Furthermore, the transmission component 203 includes an infrared transmitter 203a disposed at the top of the threaded rod 202a, an infrared receiver 203b disposed at the bottom of the insulating clamp 101a, and a control circuit 203c disposed inside the insulating connecting sleeve 103a.
[0038] It should be noted that there are two sets of infrared receivers 203b, which are respectively disposed at the bottom of the two clamping jaws of the insulating clamp 101a, opposite to the infrared transmitter 203a.
[0039] Furthermore, the control button 201b is adapted to the insulating limiting groove 103b, and the control button 201b is connected to the control circuit 203c.
[0040] It should be noted that the connection point of the control circuit 203c is arranged on the inner side of the control button 201b. When the control button 201b is pressed, it is electrically connected to the motor 201a, and the control circuit 203c is turned on. The control button 201b is divided into two buttons, "on" and "off", which respectively control the two rotation directions of the motor 201a, so that the insulating wire clamp 101a can be opened and closed.
[0041] Furthermore, the control circuit 203c is provided with a circuit breaker, and a limit hole is provided to match the circuit breaker. Both ends of the limit hole have conductive contacts. The limit block is adapted to the limit pin. The middle section of the limit pin is provided with a metal conductor, and the rest is an insulator.
[0042] Furthermore, two groups of insulating rods 103c are provided, which are connected via a cross insulating rod connector, and the other end of the control circuit 203c is connected to a control button 201b transversely penetrated in the cross insulating rod connector.
[0043] When in use, first connect the two insulating rods 103c with the cross insulating rod connector to form a whole, place the insulating wire clamp 101a at a suitable position on the overhead line through the upper end of the cross insulating rod connector, and place the insulating wire clamp 101a at a suitable position on the drainage line on the left or right side. Further, the staff presses the "close" button of the control button 201b to control the insulating wire clamp 101a at the overhead line to rotate forward, and the motor 201a drives the threaded rod 202a to rotate synchronously in the same direction through the motor 201a shaft, and the threaded rod 202a rotates synchronously in the same direction through the threaded rod 202a. The long nut 202b is driven to move downward. At this time, due to the limitation of the limit rod 102c, the long nut 202b drives the linkage rod 102a and the push rod 102b to rotate downward synchronously, so that the support frame 101b pushes the insulating wire clamp 101a to gradually tighten. When the wire clamp is tightened, if both infrared receivers receive the signal from the transmitter, the motor 201a stops; if only one of the receivers on the left and right sides receives the transmitter signal, the motor 201a continues to rotate until the two wire clamps on the left and right receive the transmitter signal at the same time, and the motor 201a stops. When the motor 201a stops rotating, the operator inserts the limit pin into the limit hole to realize mechanical locking and at the same time makes the control circuit 203c conductive through the contact between the metal conductor and the conductive contact. At this time, the insulating wire clamp 101a at the lower end drainage line and the motor 201a start to work, and the motor 201a drives the threaded rod 202a to rotate synchronously in the same direction through the motor 201a shaft. The threaded rod 202a drives the long nut 202b to move toward the inside of the insulating connecting sleeve 103a through the thread. The long nut 202b pulls the push rod 102b and the linkage rod 102a to move synchronously. Under the limit of the limit rod 102c, the support frame 101b pushes the insulating wire clamp 101a to gradually tighten and clamp the drainage line, so that the disconnected wire ends can be fixed when the distribution overhead line is disconnected and connected without power outage, preventing the drainage line from moving, thereby improving the safety of the operation.
[0044] When the work is completed, the operator pulls out the limit pin. At this time, the insulating wire clamp 101a motor 201a at the lower end drainage line no longer receives the signal from the drive circuit, and automatically drives the motor 201a to reverse, so that the wire clamp opens. Then the operator presses the "open" button of the control button 201b to reverse the insulating wire clamp 101a motor 201a at the overhead line, and the long nut 202b moves upward. The insulating wire clamp 101a releases the overhead line and disconnects from the overhead line, and the device can be removed.
[0045] In summary, the present invention ensures electrical safety when working in a live environment by using high-performance insulating materials, prevents current from passing through the device and causing harm to the operator, and can also find a fixed position for the disconnected drainage line to prevent the drainage line from swinging, reduce the possibility of short circuit, and improve safety. In addition, the modular design is adopted to facilitate assembly and disassembly, and improve work efficiency. Human-machine collaborative operation allows operators to cooperate with the device more conveniently and can adapt to the needs of different environments and work scenarios, such as high altitude and complex terrain.
