Description

Technical Field

[0001] The utility model belongs to the field of line short-circuit grounding, and particularly relates to an intelligent short-circuit grounding device. Background Art

[0002] A short-circuit grounding device is a safety short-circuit device that the power industry installs before equipment or lines undergo maintenance after power outages. It's used as a safety precaution to prevent injury to operators or equipment from sudden power surges. Current short-circuit grounding devices on the market consist of basic components such as line-end clamps and short-circuit grounding rods, providing protection during simple line maintenance. However, these devices lack electrical testing, real-time tracking and positioning, the ability to determine whether the line-end clamps are securely attached, or environmental detection capabilities, leading to potential safety incidents. In particular, when short-circuiting to ground, step voltage may exist at the grounding point, posing a risk of electric shock to personnel who accidentally approach.

[0003] In addition, in the short-circuit grounding operation of the power grid, it is necessary to manually record the operation address and operation process. The traditional paper and pen recording is inefficient and not real-time. This makes the traditional short-circuit grounding operation process complicated, the safety risk is high, the degree of work informatization is low, and it is very easy to cause safety accidents: during construction operations, the line end wire clamp is not firmly connected to the line, which causes the construction workers to be electric shocked and cause safety accidents; when the construction is completed, the device is forgotten to be released, and the most serious three-phase short-circuit safety accident is caused after reclosing, which will cause huge safety hazards to the construction workers and huge economic losses to the company; when the construction workers are carrying out construction work, unrelated personnel enter the construction area, which will pose a huge threat to the life and property safety of the construction workers and unrelated personnel.

[0034] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the relevant utility model and are not intended to limit the utility model. It should also be noted that, for ease of description, only portions relevant to the relevant utility model are shown in the accompanying drawings.

[0035] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0036] like Figure 1-Figure 5 As shown, see Figure 1 , the utility model provides an intelligent short-circuit grounding device, comprising a grounding main module and an electrical detection module 1 and a grounding sub-module 2 electrically connected to the grounding main module;

[0037] The electrical detection module 1 is connected to the wire and is used to detect the charged signal of the wire;

[0038] The grounding submodule 2 includes a wire clamp 21, a linkage switch 22, a positioning module 23 and a short-circuit grounding rod 24; the wire clamp 21 is used to clamp the wire, and an electrical contact point is installed on the wire clamp 21. The electrical contact point is electrically connected to the linkage switch 22, and the linkage switch 22 is electrically connected to the positioning module 23. The linkage switch 22 is installed on the electrical test module 1, and the positioning module 23 is used to obtain the position information of the intelligent short-circuit grounding device and receive the electrical signal of the sensor. One end of the short-circuit grounding rod 24 is connected to the wire clamp 21, and the other end of the short-circuit grounding rod 24 is grounded to achieve short-circuit power connection;

[0039] The grounding main module is used to obtain the live signal of the wire and the position information sent by the positioning module 23, and send a short-circuit grounding signal.

[0040] As a further explanation of the present invention, the linkage switch 22 is electrically connected to the positioning module 23, and its specific structure is as follows:

[0041] The switch input interface of the positioning module 23 is electrically connected to the linkage switch 22 .

[0042] During the use of this utility model, see Figure 4 and Figure 5When the intelligent short-circuit grounding device leaves the warehouse area, the positioning module 23 is started to realize the real-time positioning of the intelligent short-circuit grounding device, and upload the movement trajectory and location to the client in real time, record and save relevant information to ensure the subsequent retrieval of the device.

[0043] After the power test module 1 tests the power of the wire, it obtains a live signal and uploads it to the grounding main module. The live signal includes live and dead signals. When the grounding main module confirms that the wire is dead, it sends a short-circuit grounding signal to the client, and the staff can start short-circuit grounding at this time.

[0044] The center clamp 21 of the present invention is internally provided with a power supply circuit that can connect to the electrical contact point and the positioning module 23 and supply power to them. The power supply circuit is always connected to the positioning module 23. When not in operation, the electrical contact point is not connected to the power supply circuit. When the short-circuit grounding operation begins, the clamp 21 is clamped on the wire. If the clamp 21 is clamped, it will move toward both ends. At this time, the electrical contact point of the clamp 21 will overlap with the power supply circuit and be energized. The electrical contact point sends a signal to the linkage switch 22, which closes. The closed state indicates that the line-end clamp 21 has correctly clamped the wire and the connection between the wire and the grounding device is reliable. The closed linkage switch 22 sends a signal to the positioning module 23. After receiving the closed signal, that is, the clamping signal, the positioning module 23 confirms that the position status of the clamp 21 is "installed" and sends it to the grounding main module and the client. If the position status previously recorded by the system is "not installed" or the position information is outdated, the grounding main module will update the position status to "installed" and update the position information to reflect the latest position.

[0045] In addition, the positioning module 23 can update the position information of the line end wire clamp 21 and send the position information to the grounding main module and the client. The staff can then know that the wire clamp 21 at that position has been installed and can go to ground. The updated position information can reflect the actual position of the line end wire clamp 21, ensuring that the position data is the latest.

[0046] If the wire clamp 21 is not properly clamped to the wire, the linkage switch 22 will remain open, and the positioning module 23 will not receive a closing signal. In this case, the microcontroller will detect the abnormality and issue a warning through the alarm system, reminding the operator to check the status of the line-end wire clamp 21.

[0047] In short, the connection relationship between the wire clamp 21 and the linkage switch 22 is to ensure that the connection between the wire and the wire clamp 21 is firm, and can be fed back to the positioning module 23 through electrical signals, thereby realizing the monitoring and management of the device status.

[0048] Only when the line-end clamp 21 is securely attached to the line, meaning it's tightly connected, will the linkage switch 22 receive a signal. The positioning module 23 receives the active tag's data via a universal asynchronous serial transceiver (UASR) and uploads the attachment information to the backend, where it will be displayed on the client's Android phone or backend control system. Only when all three active tags are scanned and indicate a secure connection between the line-end clamp 21 and the line can the system prepare for a short circuit to ground. Otherwise, the system continues to wait for data.

[0049] The intelligent short-circuit grounding device includes an electrical detection system, a grounding main module and three grounding sub-modules 2. The three short-circuit grounding rods 24 in the three grounding sub-modules 2 are respectively connected to each line in the three-phase transmission line. The three active tags indicate that the linkage switches 22 in the wire clamps 21 of the three lines are all physically in contact.

[0050] When all preparations are completed, the intelligent short-circuit grounding device enters the working state and transmits data to the client in real time.

[0051] The specific architecture diagram of each module connection of the utility model is as follows Figure 5 The figure shows the interaction between the client, server, positioning communication module, microcontroller, slave module status and RFID scanning module. The following is a detailed description of each part:

[0052] Client: represents the user terminal, which may be a mobile phone, computer or other device used to request data or receive information.

[0053] Server: Responsible for processing client requests, providing data services, and receiving information uploaded by the positioning communication module.

[0054] Positioning communication module: responsible for uploading the information collected by the microcontroller to the server, and also receiving instructions from the server.

[0055] Microcontroller: As the core processor, it controls the workflow of the entire system, including receiving and processing information from the positioning communication module and sending commands to the sub-module.

[0056] Auxiliary module status: Indicates the working status of the auxiliary module, which may include location information, power level, etc.

[0057] RFID scanning module: used to identify and scan RFID tags, which may be used to track the location of items or people.

[0058] The system's workflow is as follows:

[0059] Client requests data: The user initiates a data request to the server through the client.

[0060] Server processes the request: After receiving the request, the server processes the data request and returns the result to the client.

[0061] Upload information: The positioning communication module uploads the information collected by the microcontroller to the server.

[0062] Microcontroller processes information: The microcontroller receives information uploaded by the positioning communication module and makes corresponding decisions as needed.

[0063] Slave module status update: The microcontroller updates the slave module status information as needed.

[0064] RFID scanning: The RFID scanning module scans RFID tags to obtain the location information of objects or people.

[0065] Warning system: If there is any abnormal situation, the warning system will sound an alarm to remind relevant personnel.

[0066] The data flow direction and main functions of the system are demonstrated, including data request, information upload, status update and alert functions. This design can realize remote monitoring and management of equipment and improve operational efficiency.

[0067] like Figure 5 As shown, the specific use process of this device is summarized as follows:

[0068] Step S1, start: start the system.

[0069] Step S2, initialize the system: set initial parameters and prepare to perform subsequent tasks.

[0070] Step S3, reading positioning information: obtaining the location information of the device through the UWB precise positioning system.

[0071] Step S4, electrical testing operation: using the electrical testing module 1 to detect whether the wire is energized.

[0072] Step S5, whether the wire is charged: if the wire is charged, jump to step S6; if not, continue to step S7.

[0073] Step S6, alarm: Since the wire is energized, the system issues an alarm to remind the operator to pay attention to safety.

[0074] Step S7, reading tag information: If the wire is not energized, the system reads the RFID tag information.

[0075] Step S8, whether there is anyone nearby: if there is no one nearby, jump to step S9; if there is someone nearby, continue to step S10.

[0076] Step S9, reading human sensor information: If there is no one nearby, the system reads the human sensor information.

[0077] Step S10, alarm: If there is someone nearby, the system will issue an alarm to remind the operator to pay attention to safety.

[0078] The working logic of the intelligent short-circuit grounding device is clearly demonstrated, including steps such as electrical testing, reading location information, reading tag information, and reading human sensor information. This design can ensure the safe operation of power facilities and promptly identify and address potential safety hazards.

[0079] For further explanation of the present invention, see Figure 2 , the electrical detection module 1 includes a working head 11, an electrical detection circuit 12, an alarm 13 and a ground pin 14;

[0080] The working head 11 is connected to the electric wire, and the working head 11 is connected to one end of the electric test circuit 12. The electric test circuit 12 is used to detect whether the electric wire is charged and obtain a charged signal; if the charged signal is charged, it is sent to the alarm 13. The alarm 13 is installed on the electric test circuit 12. The alarm 13 is used to send an alarm signal. The other end of the electric test circuit 12 is connected to the ground pin 14, and the ground pin 14 is connected to the ground.

[0081] The alarm device 13 includes a buzzer, and the alarm signal of the alarm device 13 is an alarm through the buzzer.

[0082] The short-circuit grounding rod 24 is connected to the wire, and its specific structure is as follows:

[0083] The short-circuit grounding rod 24 is connected to one end of the short-circuit grounding wire, and the other end of the short-circuit grounding wire is connected to the wire clamp 21 .

[0084] More specifically, see Figure 3 The short-circuit grounding rod 24 is connected to one end of the short-circuit grounding wire through the grounding rod structure 3, and the grounding rod hook is used to clamp the wire and connect the wire to the grounding rod.

[0085] The operator uses the ground rod structure 3 to clamp the wire to ensure good contact between the wire and the ground rod hook.

[0086] The purpose of the grounding rod assembly 3 is to ensure safe grounding of electrical equipment during maintenance or replacement work, preventing accidental electric shock. In the event of a malfunction in the electrical equipment, the short-circuiting grounding rod 24 provides short-circuit protection, reducing the risk of electrical accidents. The design of the grounding rod assembly 3 ensures a stable connection between the electrical wires and the short-circuiting grounding rod 24, reducing safety issues caused by poor contact.

[0087] As a further explanation of the present invention, the grounding main module further includes a microcontroller, which is electrically connected to the electrical detection module 1 and the grounding sub-module 2. The microcontroller is used to obtain a charged signal and output a short-circuit grounding signal when the charged signal is de-energized;

[0088] The microcontroller is also electrically connected to a sensor, which is installed in the grounding area. The sensor is used to detect whether there is illegal movement or approach to the grounding area, and upload the detection result to the client.

[0089] Specifically, when the positioning module 23 of a grounding submodule detects illegal movement of the module or someone in the area, it sends a signal to the grounding main module. The microcontroller receives this signal via the UART, packages the location information and timestamp, and sends it to the cloud server. Based on this data, the cloud server determines that the device has moved abnormally and immediately sends an alert to the client.

[0090] In this way, it can be ensured that problems can be discovered and handled in a timely manner even when no one is on duty, thereby ensuring the safe operation of power facilities.

[0091] As a further explanation of the present invention, the grounding sub-module 2 further includes a battery, which is connected to the positioning module 23 and the linkage switch 22 respectively, and is used to supply power to the positioning module 23 and the linkage switch 22.

[0092] As a further explanation of the present invention, the microcontroller is electrically connected to the positioning module 23 and the alarm system;

[0093] When the charged signal acquired by the microcontroller is a detection result indicating that there is electricity, the alarm system sends an alarm signal to the client.

[0094] As a further explanation of the present invention, the positioning module 23 is electrically connected to the antenna system via a radio frequency connector.

[0095] Specifically, the positioning module 23 is connected to the microcontroller via a universal asynchronous serial interface to obtain data to be transmitted. The positioning module 23 integrates the positioning data through a chip inside and transmits it to the mobile communication network through an antenna.
