Description

Technical Field

[0001] The utility model relates to the field of ground wire hanging, in particular to a wire state detection device and a ground wire hanging tool. Background Art

[0002] Currently, when performing maintenance work on the conductor ends of substations or transmission lines, it is generally necessary to correctly hook up the grounding end of the grounding wire first and then correctly hook up the conductor end of the grounding wire to ensure the safety of workers and equipment, thereby reducing the probability of electrical accidents.

[0003] Since the hooking process of the grounding end and the conductor end of the grounding wire must be strictly operated in accordance with relevant regulations and standards, most of the current judgments on the grounding wire status mostly rely on the operator's manual experience. However, this method is prone to the operator forgetting or making operating errors, resulting in the grounding wire not being properly hooked up and removed, causing safety accidents. Although it is now possible to automatically hook up grounding wires through equipment such as drones, this method of automatically hooking up grounding wires cannot always correctly hook up the conductor end, and the probability of grounding wire hooking failure is relatively high. Therefore, when hanging and removing grounding wires at the conductor end of a substation or transmission line, monitoring the status of the transmission line at the conductor end to avoid the situation where the grounding wire is not properly hung or removed becomes a key point in the grounding wire hooking process.

[0005] With regard to the technical problem in the related art that there is a lack of a detection device for accurately detecting the state of the wire, no effective technical solution has been proposed yet. Utility Model Content

[0030] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0031] It should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0032] like Figure 1 As shown, the embodiment of the utility model provides a schematic diagram of the appearance of a wire state detection device. From the current perspective, the wire state detection device includes a detection module 10, a wiring hook 20, and a micro switch 21. The detection circuit inside the detection module 10 has been electrically connected to the micro switch 21, which is used to monitor the working state of the micro switch 21 in real time, and detect the wire state of the transmission wire according to the working state of the micro switch 21. Among them, the detection module 10 is wrapped with a physical shell outside to protect the internal structure of the detection module 10.

[0033] Figure 2 is a schematic diagram of the structure of the detection device of the wire state according to an embodiment of the utility model, such as Figure 2 As shown, the detection device for the wire state includes:

[0034] A wiring hook 22, used for hooking a transmission wire;

[0035] The switch assembly 24 is disposed on the wiring hook 22, and the working state of the switch assembly 24 includes: an open state or a closed state;

[0036] The conductor state detection module 26 is connected to the switch component 24 and is used to obtain a switch electrical signal corresponding to the working state of the switch component 24 and determine the conductor state of the transmission conductor according to the switch electrical signal.

[0037] Through the utility model, a conductor state detection device including a wiring hook, a conductor state detection module and a switch assembly is proposed. This device can be applied to the grounding detection process of the ground wire at the conductor end of a substation or a transmission line, for example. The conductor state detection module is connected to the switch assembly arranged on the wiring hook, and can obtain the switch electrical signal corresponding to the switch assembly, and then determine the conductor state of the transmission conductor according to the switch electrical signal, so as to judge whether the conductor is reliably hung, and finally judge whether the wire is safely hung. It should be noted that in this embodiment, since the conductor state detection module is connected to the switch assembly, that is, the conductor state detection module is realized to receive the switch electrical signal of the switch assembly in real time, it can solve the technical problem of the lack of a detection device for accurately detecting the conductor state in the related technology, and improve the accuracy of detecting the conductor state.

[0038] It is understandable that the grounding wire is used when inspecting and repairing substations and transmission lines in order to reliably ground the substations and transmission line conductors during the inspection and repair to prevent safety accidents.

[0039] It should be noted that before using the utility model to detect the conductor state of the power transmission conductor, a grounding wire has been successfully hung at the grounding end, wherein the hung grounding wire is connected to a conductor state detection device.

[0040] It is understood that the switch assembly means a switch that has two definite states, on or off, and can switch between them. The switch assembly may include but is not limited to a pressure switch, a micro switch, a key switch, a knob switch, a Hall sensor, a proximity switch, a gas valve switch, etc.

[0041] Optionally, the switch assembly can be disposed inside the hook body of the wiring hook, such as the upper side wall or the lower side wall inside the hook body, and the present application does not impose any limitation on this.

[0042] For example, after the wiring hook is successfully hooked to the transmission wire, the switch assembly is then opened (ie, in the open state) according to the interaction force generated when contacting the wire.

[0043] Alternatively, after the above-mentioned switch assembly is successfully hooked to the transmission wire by the wiring hook, if the interaction force generated by contact with the wire is less than the force required to open the switch assembly, the switch assembly is still in a closed state; if the interaction force generated by contact with the wire is greater than or equal to the force required to open the switch assembly, the switch assembly is in an open state.

[0044] Alternatively, the switch assembly is closed without contacting the wire.

[0045] Exemplarily, in the case where the switch assembly is a micro switch, if the wiring hook is successfully hooked to the power transmission line, the micro switch is triggered to open. At this time, the micro switch is in the on state and generates a switching electrical signal.

[0046] In an optional embodiment of the present invention, the wire state detection module further includes: a state acquisition module, connected to the switch component, and used to acquire a switch electrical signal corresponding to the working state of the switch component; a controller, respectively connected to the state acquisition module and the power-on / off control module, and used to receive the switch electrical signal sent by the state acquisition module, generate a control instruction according to the switch electrical signal, and send the control instruction to the power-on / off control module; the power-on / off control module, respectively connected to the state acquisition module and the controller, and used to receive the switch electrical signal sent by the state acquisition module, and determine whether to activate the power-on / off control module according to the switch electrical signal, and also used to receive the control instruction sent by the controller, and when the power-on / off control module has been activated, determine to power the wire state detection module according to the control instruction.

[0047] For example, Figure 3 As shown, the state acquisition module 200 is connected to the micro switch 21, and the state acquisition module 200 can acquire a switch electrical signal corresponding to the working state of the micro switch 21. The controller 100 is connected to the state acquisition module 200 and the power on / off control module 300 respectively.

[0048] In an optional embodiment of the present invention, the state acquisition module includes: a switch state detection unit, which is respectively connected to the switch component and the controller, and is used to obtain a switch electrical signal corresponding to the working state of the switch component, and send the switch electrical signal to the controller; a power detection unit, which is respectively connected to the power supply battery provided in the detection device and the controller, and is used to generate a power signal according to the detected power information of the power supply battery, and send the power signal to the controller.

[0049] like Figure 4 As shown, the state acquisition module 200 includes a switch state detection unit 210 and a power detection unit 220. The switch state detection unit 210 is connected to the micro switch 21 and the controller 100 respectively. The power detection unit 220 is connected to the lithium-ion battery 700 and the controller 100 respectively.

[0050] Reference Figure 3 or Figure 4The controller 100 can receive the switch electrical signal sent by the state acquisition module 200, and interact with the switch control module 300 to realize the functions of automatic power off and shutdown of the device. Coordinate various functional modules to realize real-time detection of the grounding wire connection status of the wire end.

[0051] The switch state detection unit 210 can convert the working state of the micro switch 21 into a switch electrical signal. The lithium ion battery 700 can realize the function of the above-mentioned power supply battery. The power detection unit 220 can monitor the power of the lithium ion battery and generate a power signal according to the monitored power.

[0052] The micro switch 21 can be switched to a conducting state, that is, switched to an open state, when the wire is hooked, or switched to a disconnected state, that is, switched to a closed state, when the wire is removed.

[0053] In an optional embodiment of the present utility model, the power on / off control module includes: a jump signal detection unit, which is respectively connected to the switch state detection unit and the controller, and is used to receive the switch electrical signal sent by the switch state detection unit, generate a pulse signal according to the switch electrical signal, and receive the control instruction sent by the controller, and send the pulse signal according to the control instruction.

[0054] In this embodiment, refer to Figure 4 As shown, the on / off control module 300 includes a jump signal detection unit 310. The jump signal detection unit 310 is connected to the controller 100 and the switch state detection unit 210 respectively.

[0055] Further, such as Figure 5 As shown, the jump signal detection unit 310 includes a delay device and an XOR gate. Figure 6 As shown, the input signal IN is input to the delay device, and the signal IN2 output by the delay device after a delay of T1 is obtained, which is XORed with IN to obtain a pulse signal with a pulse width of T1.

[0056] The built-in circuit of the jump signal detection unit can output a pulse signal when a signal change is detected. When the pulse signal is input to a falling edge D flip-flop (such as the CLK clock input pin), the falling edge D flip-flop will be triggered to latch the currently input control instruction, so that the two stable state quantities corresponding to the control instruction and the pulse signal input to the controller D flip-flop can be obtained. These two stable state quantities can drive the closing and opening of the circuit, thereby controlling the power supply of the power supply battery.

[0057] In an optional embodiment of the present utility model, the power on / off control module also includes: a switch state setting unit, which is respectively connected to the jump signal detection unit and the controller, and is used to receive a pulse signal sent by the jump detection unit, and receive a control instruction sent by the controller, and latch the control instruction according to the pulse signal.

[0058] Further, such as Figure 4 As shown, in this embodiment, the on / off control module 300 further includes a switch state setting unit 320. The switch state setting unit 320 is connected to the jump signal detection unit 310 and the controller 100 respectively.

[0059] In an optional embodiment of the present utility model, the power on / off control module also includes: a power switch unit, which is respectively connected to the controller, the switch state setting unit and the power supply battery, and is used to receive the control instruction sent by the switch state setting unit, and control the circuit between the power switch unit and the power supply battery to be connected according to the control instruction, so as to control the power supply battery to supply power to the wire state detection module, or control the circuit between the power switch unit and the power supply battery to be disconnected according to the control instruction, so as to control the power supply battery to cut off power to the wire state detection module.

[0060] Further, such as Figure 4 As shown, in this embodiment, the power on / off control module 300 further includes a power switch unit 330. The power switch unit 330 is connected to the controller 100 and the switch state setting unit 320 respectively.

[0061] It is understandable that the power switch unit is also connected to a power supply battery ( Figure 4 (not shown). The power supply battery refers to a power source for supplying power to the wire state detection device. For example, it may include a lithium-ion battery, but is not limited thereto.

[0062] In an optional embodiment of the utility model, the switch state setting unit also includes: a trigger, which is respectively connected to the controller, the jump signal detection unit and the delay device, and is used to receive the pulse signal sent by the jump signal detection unit and the control instruction output by the controller, latch the control instruction according to the pulse signal, and send the control instruction to the delay device; the delay device is respectively connected to the trigger and the power switch unit, and is used to receive the control instruction sent by the trigger, and send the control instruction to the power switch unit after a preset delay time period.

[0063] like Figure 7As shown, the switch state setting unit 320 includes a falling edge D flip-flop and a delay device. The output signal "310-320" of the jump signal detection unit 310 is input to the D flip-flop, and the output signal "100-320" of the controller (which can be understood as the above-mentioned control instruction) is input to the D flip-flop. In this way, when the jump signal detection unit 310 outputs the pulse signal 100-320, the D flip-flop can be triggered to latch the state of the pulse signal "100-320", and then output "100-320" after a delay of T2 by the delay device.

[0064] Among them, "310-320" can be understood as the flow direction of the signal, that is, the process of sending from the jump signal detection unit 310 to the switch state setting unit 320. The meanings of other similar expressions in this application can refer to this content and will not be repeated here.

[0065] Through the above embodiments, it can be seen that the power on / off control module 300 specifically includes a jump signal detection unit 310, a switch state setting unit 320 and a power switch unit 330. The jump signal detection unit 310 can output a pulse signal according to the switch electrical signal. The switch state setting unit 320 can control the on / off of the circuit between the power switch unit 330 and the power supply battery and thus control the power supply battery to supply or cut off. In other words, combined with Figure 5 and Figure 7 The structure can be understood as the power on / off control module being able to change the grounding state of the ground wire through specific circuit devices such as a delay device, a NOR gate, and a D flip-flop, thereby controlling the power supply to power on or off the wire state detection device, thereby realizing automatic power on / off of the wire state detection device.

[0066] In an optional embodiment of the utility model, the device also includes: a status indication module, connected to the controller, and the status indication module includes at least one of the following: an indicator light unit, a buzzer unit, and a vibrator unit; the indicator light unit is used to indicate the working status of the wire status detection module through different light signals; the buzzer unit is used to indicate the working status of the wire status detection module through different sound signals; the vibrator unit is used to indicate the working status of the wire status detection module through different vibration signals.

[0067] like Figure 3 As shown, the controller 100 is also connected to a status indication module 400, which can indicate that the battery power is low, or indicate the grounding state of the wire end (ie, the grounding wire connection state of the wire end).

[0068] The state indicating module 400 may include an indicator light unit 410, a buzzer unit 420 and a vibrator unit 430. The controller 100 sends different control instructions to the state indicating module 400, thereby controlling the indicator light unit 410 to indicate the working state of the wire state detection module through different light signals, or controlling the buzzer unit 420 to indicate the working state of the wire state detection module through different sound signals, or controlling the vibrator unit 430 to indicate the working state of the wire state detection module through different vibration signals.

[0069] It should be noted that the above-mentioned indicator light unit can realize indicator light warning, specifically, by controlling the light color, light flashing frequency, etc. of LED lights or other types of light sources in the device or system to issue a warning signal. When an abnormal situation or a problem that requires attention occurs, the indicator light will flash or change color to remind the user to take corresponding measures. The advantage of this method is that it is intuitive and easy to observe, and is particularly suitable for use in good lighting conditions.

[0070] Optionally, the buzzer unit can realize buzzer warning, specifically by controlling the buzzer to emit sound signals of different tones or frequencies to remind the user. The buzzer can emit sounds of different frequencies, durations and intervals to indicate different types of alarms. The advantage of this method is that it can be heard at a longer distance, and is suitable for noisy environments or occasions where sound prompts are required.

[0071] For example, the vibrator unit can realize a vibrator warning, specifically by controlling the vibrator to generate vibrations of different frequencies or intensities to alert the user. This method can penetrate various environments well and effectively transmit alarm information even in noisy environments. In addition, the vibrator warning will not interfere with the surrounding environment and is suitable for occasions where quietness is required.

[0072] In an optional embodiment of the present invention, the device further includes: an information storage module, which is connected to the databases corresponding to the controller and the detection device respectively, and is used to receive different control instructions sent by the controller and send the different control instructions to the database.

[0073] like Figure 3 As shown, the controller 100 is also connected to an information storage module 500. The information storage module 500 can further store the control time corresponding to the control instruction and the control type corresponding to the control instruction.

[0074] In an optional embodiment of the utility model, the device also includes: a wireless communication module, the wireless communication module includes at least one of the following: a Bluetooth communication unit, a ZigBee communication unit, a radio frequency communication unit, an infrared communication unit, a sensor communication unit, the wireless communication module is connected to the controller, and is used to receive the operation information of the wire status detection module, and send the operation information to the communication device.

[0075] like Figure 3 As shown, the wireless communication module is, for example, a Bluetooth communication module 600, which can upload the control instruction sent by the controller 100, the control time corresponding to the control instruction, and the control type corresponding to the control instruction to the database.

[0076] It should be noted that the above-mentioned conductor state detection device has two states: working state and shutdown state. When the ground wire is not being hung or removed, it will automatically enter the shutdown state, and the automatic shutdown time can be freely configured.

[0077] In an optional embodiment of the present utility model, the internal module interaction logic of the above-mentioned wire state detection device is described in the following manner:

[0078] For the start-up of the wire status detection device, refer to Figure 8 The startup timing diagram when the ground wire is connected and Fig. 9 The power-on timing diagram when the ground wire is removed, where the low level is 0 and the high level is 1. If it changes from a high level to a low level, it corresponds to the situation where the ground wire is connected, and if the low level changes to a high level, it corresponds to the situation where the ground wire is removed.

[0079] When the working state of the micro switch changes, the switch state detection unit 210 changes the level of the output signal “210-310” according to the working state of the micro switch, and sends “210-310” to the jump signal detection unit 310 .

[0080] The jump signal detection unit 310 outputs a pulse signal with a pulse width T1 according to "210-310", and sends the pulse signal to the switch state setting unit 320 to trigger the switch state setting unit 320 to latch the output signal "100-320" of the controller 100. The switch state setting unit 320 outputs a signal "320-330" to the power switch unit 330 based on the received "100-320", and then the power switch unit 330 controls the power supply to supply power to the wire state detection device according to the received "320-330", and the wire state detection device is turned on.

[0081] In particular, the output signal "320-330" output by the switch state setting unit 320 to the power switch unit 330 is as follows: when "320-330" is at a low level, the power switch of the power supply is closed, and when "320-330" is at a high level, the power switch of the power supply is opened.

[0082] For the shutdown of the wire status detection device, refer to Fig.10 According to the shutdown timing diagram provided, the controller 100 switches the output signal "100-320" sent to the switch state setting unit 320 from a low level to a high level. After an interval of T3, the controller 100 switches the "100-310" sent to the jump signal detection unit 310 from a low level to a high level.

[0083] The jump signal detection unit 310 outputs a pulse signal with a pulse width T1 according to the changed "100-310", and sends the pulse signal to the switch state setting unit 320, thereby triggering the switch state setting unit 320 to latch the state of the output signal "100-320" of the controller, and then sets the internal power switch of the power switch unit 330 to disconnect, controlling the power supply to cut off the power to the wire state detection device to shut down the wire state detection device.

[0084] In particular, the power on / off control module 300 has a shutdown self-reset function. After the wire status detection device is powered off and shut down, the output signals "100-310" and "100-320" can be reset, that is, "100-310" and "100-320" are reset to a low level, so that the wire status detection device can be turned on normally in the above order when the ground wire is restored.

[0085] It should be noted that by powering off the wire status detection device, the wire status detection device is shut down, providing an ultra-low power consumption mode for the wire status detection device, and greatly improving the battery life of the wire status detection device.

[0086] When the wire state detection device detects a change in the grounding state of the ground wire through the state acquisition module, the power on / off control module can be used to control the wire state detection device to quickly switch from the shutdown state to the working state. When the wire state detection device is in the shutdown state, the system working power supply of all modules except the power on / off control module will be directly cut off, and the power on / off control module will be powered by the power supply battery.

[0087] As another embodiment of the present utility model, a ground wire hanging tool is provided, comprising: a wire end hanging part, which is equipped with a wire state detection device as described in any one of the above embodiments.

[0088] Specific as Fig.11As shown, the wire end hooking portion 1101 of the ground wire hooking tool 110 is equipped with a wire state detection device 1102.

[0089] It is understandable that the above-mentioned grounding wire hooking tool may also include a grounding terminal hooking part for hooking the grounding wire and detecting the grounding wire state of the grounding terminal. The process of the grounding wire hooking part realizing the above functions may refer to the technical solutions in the relevant field, and this application will not describe it in detail.

[0090] The above-mentioned wire state detection device of the utility model has a simplified structure, fewer parts, and a reliable circuit that is easy to implement. In addition, the power on / off control module realizes automatic power on / off of the wire state detection device by controlling the power supply to be powered on or off, so that the wire state detection device has a low power consumption mode, the efficiency of the power supply is greatly improved, the intelligent management of the wire state is realized, and the accuracy of detecting the wire state is improved, thereby meeting the high safety and high reliability requirements required for the maintenance of the substation and the wire end of the transmission line.
