[0002] A temporary grounding device is a safety mechanism installed in the power industry after a power outage and before maintenance. It is used to prevent injury to operators or equipment from sudden power restoration. In existing technology, temporary grounding devices are generally connected to a conductor to guide the current and charge on the conductor.

[0003] While this method can meet the grounding requirements, it is prone to problems because the temporary grounding device can easily detach from the conductor under external force, and this detachment is difficult for workers to detect. This can easily create safety hazards. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a temporary grounding device. To achieve the above objectives, this utility model adopts the following technical solution:

[0006] The clamping mechanism includes a clamping part and a monitoring part disposed opposite to the clamping part, which allows monitoring of grounding information. The clamping part and the monitoring part together form a cavity that allows the conductor to be accommodated.

[0007] Furthermore, the clamping mechanism also includes a first fixing part disposed on the outer side of the monitoring part along the axial direction, and a second fixing part disposed between the first fixing part and the clamping part to connect the clamping part and the first fixing part together.

[0008] Furthermore, the driving part is configured as a threaded rod connected to the monitoring part, and a threaded hole that cooperates with the threaded rod is provided on the first fixing part, so that the driving part can drive the monitoring part to move as it rotates along the threaded hole.

[0009] Furthermore, a meandering portion is provided on the radially inner side of the clamping portion. The meandering portion is constructed as an arc-shaped structure that is concave outward along the axial direction, so that when the conductor is placed in the cavity, the conductor can form a surface contact with the clamping portion.

Detailed Implementation

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0024] To better understand the purpose, structure, and function of this utility model, a temporary grounding device of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] Figure 1 The schematic diagram illustrates the overall structure of the temporary grounding device according to this utility model. In such a way... Figure 1 In the embodiment shown, the temporary grounding device 100 includes a clamping mechanism 1, which is configured to clamp a conductor (not shown) and allow it to conduct electricity with the conductor.

[0026] A connecting mechanism 2 is also provided on the clamping mechanism 1, which is configured to allow the grounding wire (not shown in the figure) to be connected to each other. In this way, the current and charge from the conductor are transferred to the grounding wire via the connecting mechanism 2 after passing through the clamping mechanism 1, and then conducted into the grounding grid through the grounding wire. Thus, the grounding operation is achieved.

[0027] The clamping mechanism 1 includes a clamping part 11 and a monitoring part 12 disposed opposite to the clamping part 11, which allows monitoring of grounding information. In this way, the clamping part 11 and the monitoring part 12 are configured together to form a cavity 13 that allows for the accommodation of a conductor.

[0028] In this configuration, when temporary grounding of a conductor (not shown in the figure) is required, the conductor is first placed inside the cavity 13, with the clamping part 11 and the monitoring part 12 respectively abutting against each other. Simultaneously, a grounding wire (not shown in the figure) is placed on the connecting mechanism 2, and the grounding wire is fixed relative to the connecting mechanism 2. Furthermore, the free end of the grounding wire is connected to the grounding grid. This completes the arrangement of the device 100.

[0029] During this process, the current and charge on the conductor are transferred to the connecting mechanism 2 after passing through the clamping mechanism 1, and then transmitted to the grounding wire via the connecting mechanism 2. At this time, the current and charge will be transmitted to the grounding grid under the guidance of the grounding wire. Thus, the grounding guidance work is completed.

[0030] In one embodiment, such as Figure 1 As shown, the clamping mechanism 1 further includes a first fixing part 14 disposed on the outer side of the monitoring part 12, and a second fixing part 15 disposed between the first fixing part 14 and the clamping part 11. The second fixing part 15 is configured to allow the clamping part 11 and the first fixing part 14 to be fixed together relative to each other.

[0031] At the same time, such as Figure 1 As shown, a driving part 141 is also provided on the first fixing part 14. The driving part 141 is configured to allow selective driving of the monitoring part 12 to adjust the axial length of the cavity 13. In this way, the device 100 can clamp conductors of different specifications. This increases the applicability of the device 100.

[0032] In this embodiment, as Figure 1As shown, the driving part 141 is configured as a threaded rod, and the end of the threaded rod is connected to the monitoring part 12. Simultaneously, a threaded hole that mates with the threaded rod is also provided on the first fixing part 14. In this way, as the threaded rod rotates along the threaded hole, it can drive the monitoring part 12 to move, thereby adjusting the axial length of the cavity 13.

[0033] According to a preferred embodiment of the present invention, such as Figure 1 As shown, a meandering portion 111 is also provided on the radially inner side of the clamping portion 11. In this embodiment, the meandering portion 111 is configured as an arc-shaped structure that is concave outward along the axial direction. In this way, when the conductor is placed in the cavity 13, the conductor can be located within the meandering portion 111, and a surface contact can be formed between the conductor and the meandering portion 111. As a result, the conductor can be further stably connected to the device 100.

[0034] In one embodiment, such as Figure 1 As shown, a handle 142 is also provided at the free end of the drive unit 141, and the handle 142 is configured in any shape that is easy to hold. In this way, it is easy to apply force toward the drive unit 141. Thus, it is easy to actuate the drive unit 141 to rotate along the first fixed part 14.

[0035] In this configuration, when it is necessary to place the conductor in the cavity 13 and guide the current and charge on the conductor, the conductor is first placed in the cavity 13 and the conductor and the detour section 111 are brought into contact with each other.

[0036] Simultaneously, the operator holds the handle 142 and applies a circumferential force to it. During this process, the force causes the drive unit 141 to rotate along the first fixed part 14, thereby driving the monitoring unit 12 to move axially until the monitoring unit 12 comes into contact with the conductor. This completes the clamping of the conductor.

[0037] At this time, a grounding wire (not shown in the figure) is placed on the connecting mechanism 2, and the grounding wire is fixed together with the connecting mechanism 2. At the same time, the grounding wire is connected to the grounding grid. Thus, the arrangement of the device 100 is completed. During this process, the current and charge on the conductor can be transferred to the connecting mechanism 2 after passing through the clamping mechanism 1, and then transmitted to the grounding wire via the connecting mechanism 2.

[0038] At this time, the current and charge will be transmitted to the grounding grid under the guidance of the grounding wire. Thus, the grounding guidance process is completed. In this embodiment, two connecting mechanisms 2 are provided, each constructed as a columnar structure, for interconnection with the grounding wire.

[0039] In one embodiment, such as Figure 2 As shown, the monitoring unit 12 includes a limiting part 121 for carrying a conductor, and an information monitoring component 122 disposed on the limiting part 121, the information monitoring component 122 being configured to allow monitoring of grounding information.

[0040] In this embodiment, as Figure 2 , 3 As shown, the information monitoring component 122 includes an information processing module 1221, and an acceleration sensing module 1222 and a gyroscope sensing module 1223 respectively connected to the information processing module 1221.

[0041] The acceleration sensing module 1222 and the gyroscope sensing module 1223 are configured to allow the position of the limiting part 121 to be monitored and the monitoring results to be transmitted to the information processing module 1221. The information processing module 1221 is configured to allow the information to be transmitted to a terminal (not shown in the figure) and displayed explicitly on the terminal.

[0042] It should be noted that, as Figure 2 , 3 As shown, the methods and principles by which the accelerometer sensor module 1222 and the gyroscope sensor module 1223 monitor the position of the limiting part 121 are well known to those skilled in the art. Furthermore, the method by which the accelerometer sensor module 1222 and the gyroscope sensor module 1223 transmit the monitored information to the information processing module 1221, and then to the terminal for explicit display, is also well known to those skilled in the art. Therefore, it will not be elaborated further here.

[0043] In this configuration, such as Figure 2 , 3 As shown, when the limiting part 121 disengages from the conductor, the acceleration sensing module 1222 will sense this and transmit the sensed information to the information processing module 1221. At this time, the signal from the information processing module 1221 will be transmitted to the terminal, and the terminal will display the information that the limiting part 121 and the conductor have disengaged. This serves as a reminder to the staff.

[0044] However, when the limiting part 121 vibrates on the conductor, the gyroscope sensing module 1223 will sense this and transmit the sensed information to the information processing module 1221. At this time, the signal located in the information processing module 1221 will be transmitted to the terminal, and the information about the vibration of the limiting part 121 on the conductor will be displayed explicitly on the terminal. This allows for a reminder to the staff.

[0045] In one embodiment, such as Figure 2 ,3 As shown, the monitoring unit 12 also includes a pressure sensing module 1224 connected to the information processing module 1221. The pressure sensing module 1224 is configured to monitor the pressure applied by the limiting part 121 towards the conductor and transmit the monitored pressure information to the terminal, where it is displayed explicitly. This method prevents damage to the conductor due to excessive pressure. Furthermore, in this configuration, when the pressure exerted by the limiting part 121 on the conductor changes (such as loosening between the limiting part and the conductor), the pressure sensing module 1224 will transmit the monitored pressure information to the terminal and display it explicitly, thus alerting the staff.

[0046] In one embodiment, such as Figure 2 , 3 As shown, the monitoring unit 12 also includes an alarm module 1225, which is connected to the information processing module 1221. The information processing module 1221 is configured to transmit monitored information from the acceleration sensor module 1222, gyroscope sensor module 1223, and pressure sensor module 1224 to the alarm module 1225. The alarm module is activated when the acceleration sensor module 1222 senses that the limiting part 121 and the conductor have separated; when the gyroscope sensor module 1223 senses that the limiting part 121 is vibrating; or when the pressure sensor module 1224 senses that the force exerted by the limiting part 121 on the conductor exceeds a threshold. This serves as a reminder to the staff. It should be noted that the threshold is manually set.

[0047] According to a preferred embodiment of the present invention, such as Figure 2 , 3 As shown, the monitoring unit 12 also includes a power supply module 1226, which is configured to provide power to the information processing module 1221, the acceleration sensing module 1222, the gyroscope sensing module 1223, the pressure sensing module 1224, and the alarm module 1225. In this way, the information processing module 1221, the acceleration sensing module 1222, the gyroscope sensing module 1223, the pressure sensing module 1224, and the alarm module 1225 can stably monitor the information from the limit unit 121.

[0048] It should be noted that the structures of the information processing module 1221, the acceleration sensing module 1222, the gyroscope sensing module 1223, the pressure sensing module 1224, and the alarm module 1225, as well as their collaborative relationships, are well known to those skilled in the art. Therefore, they will not be described in detail here.

[0049] The operation of the temporary grounding device 100 according to this utility model is as follows.

[0050] First, the conductor is placed inside the cavity 13, and the conductor abuts against the detour portion 111. Simultaneously, an operator holds the handle 142 and applies a circumferential force to it. During this process, the force causes the drive portion 141 to rotate along the first fixed portion 14, thereby causing the monitoring portion 12 to move axially until the limiting portion 121 abuts against the conductor. This completes the clamping of the conductor.

[0051] At this point, a grounding wire (not shown in the figure) is placed on the connecting mechanism 2, and the grounding wire is fixed to the connecting mechanism 2. Simultaneously, the free end of the grounding wire is connected to the grounding grid. This completes the arrangement of the device 100. During this process, the current and charge on the conductor are transferred to the connecting mechanism 2 after passing through the clamping mechanism 1, and then transmitted to the grounding wire via the connecting mechanism 2. In this process, the current and charge are guided to the grounding grid by the grounding wire. This completes the grounding guidance process.

[0052] Simultaneously, in this manner, the acceleration sensing module 1222 continuously monitors the positional relationship between the limiting part 121 and the conductor. When the limiting part 121 disengages from the conductor, the acceleration sensing module 1222 transmits the sensed information to the information processing module 1221, which then activates the alarm module 1225. The information processing module 1221 also transmits this information to the terminal, where it is displayed explicitly, thus alerting the staff.

[0053] In addition, the gyroscope sensing module 1223 and the pressure sensing module 1224 will continuously monitor the positional and pressure relationships between the limiting part 121 and the conductor, and continuously transmit the monitored information to the information processing module 1221. The information processing module 1221 will selectively activate the alarm module 1225 and allow the information to be transmitted to the terminal for explicit display. This serves as a reminder to the staff.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
