Description

Technical Field

[0001] The utility model belongs to the technical field of power outage maintenance of electrical equipment, and specifically relates to a sign hanging device capable of remote monitoring and having a work ticket status locking function. Background Art

[0002] When electrical equipment in a power system is shut down for maintenance, hanging equipment maintenance signs is an important safety technical measure. The purpose is to remind maintenance personnel of the location of the equipment to be repaired, and to prevent maintenance personnel from accidentally entering the equipment compartment and causing risks to running equipment, or accidentally touching running equipment and causing injury to maintenance personnel. Currently, equipment maintenance signs generally consist of a hanging end and a sign, with a single structure and function. After the sign is hung, the following problems may occur:

[0003] 1. No locking function for installation and removal. Currently, there is no locking function for the operation of the sign. Anyone can remove the hung sign at any time.

[0004] 2. No remote status monitoring function. Currently, after a sign is hung, its status cannot be remotely monitored. Its status can only be monitored on-site, resulting in a delay in detecting changes in the sign's status. If an equipment maintenance sign is mistakenly removed, changes in the sign's status cannot be detected in a timely manner, posing a risk to maintenance personnel and operating equipment.

[0005] 3. It is impossible to lock the hanging status of the sign through technical measures. Utility Model Content

[0013] Furthermore, a memory rebound metal wire is provided on the position state pressing piece, so that the position state pressing piece has a tendency to recover its deformation when it is not under pressure.

[0014] Furthermore, the locking device also includes an electromagnetic closer; when the electromagnetic closer is energized, it generates a force to drive the mechanical bayonet and the hanging port to form a closed state; when the position switch is pressurized, it can trigger the electromagnetic closer to be energized.

[0024] Example 1:

[0025] See attached Figures 1-2This embodiment provides a hanging device for hanging a sign through a hanging opening. The hanging opening is internally formed with a control device, a locking device, and a signal transmission device. The locking device includes a mechanical bayonet 1, which is an inverted U-shaped structure. One side of the U closes the hanging opening, and the other side contacts a position locking block 2, confining the U-shaped mechanical bayonet 1 to a closed state with the hanging opening. A memory rebound wire 7 is provided within the mechanical bayonet 1, which causes the mechanical bayonet 1 to have a counterclockwise movement tendency. The position locking block 2 is also provided with a memory rebound wire 7. At the same time, the position locking block 2 is provided with an energized retractable drive wire 3. When the energized retractable drive wire 3 is not energized, the memory rebound wire 7 is also in a stress-free state. When the energized retractable drive wire 3 is energized, it drives the position locking block 2 to rotate counterclockwise. When the energized retractable drive wire 3 is de-energized, the memory rebound wire 7 returns to its original state due to the force of the memory rebound wire 7. The energized retractable drive wire 3 can be briefly energized by pressing the sign operation button 8 of the control device. In normal standby mode, the electromagnetic closer 4 is not energized, the energized retracting drive wire 3 is not energized, the mechanical bayonet 1 and the hanging port are in a closed state, and the working principle of the hanging sign is as follows:

[0026] Press the nameplate operation button 8, the power-on retraction drive wire 3 is briefly energized and retracted, the position locking block 2 rotates counterclockwise, and the position limit of the mechanical bayonet 1 is released. At the same time, the mechanical bayonet 1 rotates counterclockwise by a certain angle under the action of the memory rebound wire 7, opening the hanging mouth, and the nameplate can be hung at this time.

[0027] In order to prevent the sign from being removed at will by other unrelated personnel after it is hung, a position status pressure piece 6 is provided on the hanging mouth, a position switch 5 is provided below the position status pressure piece 6, and an electromagnetic closer 4 connected to the position switch 5 wire is provided at the corresponding position of the mechanical bayonet 1. When the sign is hung on the hanging mouth, its own gravity presses down the position status pressure piece 6 and then touches the position switch 5, and the connecting wire energizes the electromagnetic closer 4. The electromagnetic closer 4 is energized after a delay. Under the action of electromagnetic force, the mechanical bayonet 1 moves clockwise to lock the hanging mouth. At this time, the position locking block 2 is restored to its initial state again under the action of the memory rebound wire 7. The hanging mouth is in a closed state and the sign cannot be removed.

[0028] To further realize the signal transmission of the hanging status of the sign, the signal transmission device includes a WiFi chip module 11 and a background management system that receives the WiFi chip module 11. The WiFi chip module 11 is electrically connected to the position switch 5. By detecting the pressed and unpressed states of the position switch 5, the WiFi chip module 11 transmits the signal that the sign has been hung or removed to the background management system. The WiFi chip module 11 uses internal WiFi communication to establish a communication connection with the surrounding routers, and the routers then interact with the background management system for real-time information communication, thereby realizing reliable monitoring of the status of the sign.

[0029] The further working process of removing the sign is as follows: the control device is also provided with a human body sensing sensor 9 and a battery 12, and the battery 12 is connected to the human body sensing sensor 9, the WiFi chip module 11, the electromagnetic absorber 4, and the position switch 5 through wires and is powered on for operation. When the human body is close to the human body sensing sensor 9, the electromagnetic absorber 4 is powered off (the electromagnetic absorber 4 can be powered by the pressure of the position switch 5, and the power is cut off after the human body sensing sensor 9 senses the human body. Its internal circuit system can realize the control logic through existing technology), and there is no longer a force to drive the mechanical bayonet 1 to move clockwise. At this time, after pressing the sign operation button 8, the power is turned on and the retracting drive wire 3 is briefly energized and retracted, and the position locking block 2 rotates counterclockwise, releasing the position limit of the mechanical bayonet 1. At this time, the mechanical bayonet 1 rotates counterclockwise by a certain angle under the action of the memory rebound wire 7, and the hanging port is opened, and the equipment maintenance sign can be removed;

[0030] Part of the position locking block 2 is located outside the overall structure, and can be manually pressed to rotate the position locking block 2 counterclockwise. For example, if the battery 12 is low, the emergency card removal button cover 13 can be opened and the emergency card removal button can be pressed to rotate the position locking block 2 counterclockwise by a certain angle, thereby releasing the position limit of the mechanical bayonet 1. At the same time, the mechanical bayonet 1 rotates counterclockwise by a certain angle under the force of the memory rebound wire 7, opening the hanging hole, and the sign can now be removed.

[0031] The electromagnetic coil in the electromagnetic attractor 4, the WiFi chip module 11, the human body sensing sensor 9, the power conversion module 10, the position switch 5 and the electrical control circuit composed of the power supply, the specific control logic can be referred to the existing technology and will not be repeated here.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
