Problems solved by technology

At present, the power grounding rod must rely on external sensors to detect the connection state in order to obtain the connection state. There is a loophole in the remote supervision of electric power operation. Operators are prone to safety accidents due to irregular operations and cannot safely supervise on-site operations.

Embodiment 1

[0022] Embodiment 1: The sensor is a mechanical trigger switch. The mechanical trigger switch is composed of a trigger switch cap 3 that can move up and down and a trigger switch 5 for sensing the movement of the trigger switch cap 3. The trigger switch cap 3 is connected to the hook 2 A return spring 4 is provided between the bent parts of the trigger switch cap 3 so that it is in a spring-open state when it is not triggered.

[0023] In the first embodiment, the curved part of the hook 2 is provided with a gland 11 for positioning the upper end of the return spring 4, and the curved part of the hook 2 is provided with a trigger switch cap mounting seat 12, and the trigger switch cap mounting seat 12 is provided with a trigger switch mounting seat 13; during hooking operation: the trigger switch cap 3 moves upwards and touches the trigger switch, and the trigger switch 5 obtains the hooking action information and feeds it back to the acquisition device, and the acquisition dev...

Embodiment 2

[0024] Embodiment 2: The curved part of the hook 2 is provided with a trigger switch cap 3 that can move up and down, and there is a device between the trigger switch cap 3 and the curved part of the hook 2 so that the trigger switch cap 3 is bounced off when it is not triggered. The return spring 4 of the state, the Hall device or the magneto-sensitive resistor triggers the movement of the switch cap 3 to determine the hooking state of the grounding wire. In other words, in the second embodiment, the trigger switch 5 in the first embodiment is replaced by a sensor device such as a Hall device or a magnetoresistor that can effectively detect metal proximity. At this time, the trigger switch cap 3 is at least partially made of metal.

[0025] In the second embodiment, the curved part of the hook 2 is provided with a gland 11 for positioning the upper end of the return spring 4, and the curved part of the hook 2 is provided with a trigger switch cap mounting seat 12, and the trig...

Embodiment 3

[0026] Embodiment 3: The sensor is a Hall device or a magneto-sensitive resistor that can effectively detect metals close to it, and collects the hooking action information through changes in the electric field or magnetic field. Improve detection sensitivity or a permanent magnet with a large magnetic energy product; in other words, in the third embodiment, the mechanical trigger switch in the first embodiment is replaced by a Hall device or a magneto-sensitive resistor. When the hook 2 hooks the connecting wire, the Hall device or the magneto-sensitive resistor obtains the hooking action information and feeds it back to the acquisition device. The acquisition device can send the location, time, personnel and operation conditions of the on-site operation to the remote monitoring through the wireless communication module. center.

[0027] In Embodiment 1, Embodiment 2 and Embodiment 3, the inside of the hook 2 is provided with a clip 6 for clamping the grounding wire. The upp...

Abstract

The invention relates to an intelligent hanging-connection trigger mechanism of a grounding terminal. The intelligent hanging-connection trigger mechanism comprises a rod body, wherein a hook is arranged at the upper end of the rod body. The intelligent hanging-connection trigger mechanism is characterized in that a bent portion of the hook is provided with a sensor for sensing the hanging-connection state of a grounding line, and the sensor is a mechanical trigger switch or a hall element or a magneto-sensitive resistor. By embedding the sensor on the hook, the intelligent hanging-connection trigger mechanism achieves effective recognition on hanging-connection actions of operation staff, so that a report to an upper level is facilitated, the hanging-connection operation is easy, working is reliable, security accidents are greatly reduced, and remote monitoring on field operation is facilitated.

Description

technical field [0001] The invention relates to an intelligent grounding terminal hook trigger mechanism, which belongs to the field of intelligent monitoring of power systems. Background technique [0002] The real-time acquisition of the connection status of electric grounding rods (also known as intelligent grounding terminals or grounding rods) plays a key role in monitoring the status of electric grounding rods. Summarizing the uploaded information to on-site / remote monitoring personnel can ensure the on-site operation status of electric personnel. Real-time feedback enhances the safety supervision of power operations. At present, the connection state of electric grounding rods must rely on external sensors to detect the connection state. There is a loophole in the remote supervision of electric power operation. Operators are prone to safety accidents due to irregular operations and cannot safely supervise on-site operations. Contents of the invention [0003] In vie...
