DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] The purpose of the present invention is to provide a grounding wire system to solve the problems existing in the above-mentioned prior art and to be able to judge the hanging state and hanging posture of the grounding wire in real time.

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] The hanging status of the grounding wire is often difficult to judge accurately, and is usually judged subjectively by the operator. However, it is difficult for the operator to accurately judge whether the grounding wire has been correctly hung, which may cause the grounding wire to fail to play its due role at a critical moment, thereby increasing the risk of safety accidents. In actual operation, the hanging posture of the grounding wire may deviate from the standard due to various reasons, resulting in various hanging problems, such as inaccurate hanging position, inappropriate hanging angle, etc. These posture problems may affect the conductive properties of the grounding wire, and then threaten the safety of the operator and the safe operation of the equipment. In order to avoid this problem, it is necessary to design a technical solution that can monitor the hanging status and hanging posture of the grounding wire in real time. To this end, the present invention provides a grounding wire system, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, it includes a conductive wire clamp assembly 1 and a placement bin 2. The conductive wire clamp assembly can clamp the grounding wire, and a pressure sensor 6 is provided at the clamping position. The pressure sensor 6 of this embodiment is a thin film-shaped resistive strain gauge pressure sensor, which can collect the pressure change at the moment of clamping the grounding wire; the placement bin 2 is connected to one end of the conductive wire clamp assembly 1, and a circuit board with a known mature structure is provided therein. The circuit board is equipped with a single-chip microcomputer, a 4G wireless communication module, a posture sensor and a GPS+Beidou dual-mode positioning module, all of which are known mature structures; the posture sensor can measure the posture information of the grounding wire; the single-chip microcomputer is electrically connected to the pressure sensor 6 and the posture sensor, and can receive pressure and posture data. The 4G wireless communication module, that is, the 4G communication module, can use the mobile communication network to upload the collected pressure and posture data to the cloud server in real time.

[0032] When working, the posture sensor placed in the placement bin 2 can accurately read the current posture data of the device of the present invention. The single-chip microcomputer receives the data and sends it to the cloud server of the cloud platform. The cloud server can see the posture of the grounding wire system at this time. When the hanging angle deviation is large, it can be discovered in time, and the abnormal posture problem is sent to the mobile terminal and the grounding wire system, and the staff can handle it in time. The pressure sensor 6 is bonded to the clamping position of the grounding wire. When the grounding wire is hung and clamped, the resistance value of the pressure sensor 6 will change, corresponding to the change in the value of the pressure sensor 6. The data is sent to the single-chip microcomputer through the data volume port. After the single-chip microcomputer receives the data, it is converted into a pressure value and sent to the cloud platform. The cloud platform determines whether it is correctly hung by analyzing whether the pressure value meets the correct hanging threshold.

[0033] In order to make the posture of the present invention meet the requirements when in use and improve safety, in one embodiment, a hollow insulating rod 3 is designed, and a cylinder with a protruding mortise and tenon structure connected to the hollow insulating rod 3 is left at the lower end of the placement chamber 2. The cylinder is directly inserted into the hollow insulating rod 3 and screwed into the side to achieve connection. The main function of the hollow insulating rod 3 is to extend the length when the staff is hanging it, and because it is an insulating material, it can effectively prevent electric shock accidents.

[0034] In one embodiment, the conductive wire clamp assembly 1 includes a hook body 9 and a wire clamping tongue 4 made of metal material, the wire clamping tongue 4 is provided in the hook body 9, the hook body 9 includes a smooth bent rod 901, one end of the bent rod 901 is integrally formed with a hook rod 902, and the other end is integrally formed with a connecting rod 903; the wire clamping tongue 4 is an arc-shaped rod structure, and one end of the wire clamping tongue 4 is hinged to the end of the hook rod 902 away from the bent rod 901, and the other end is abutted against the inner wall of the connecting rod 903, and the pressure sensor 6 is arranged on the inner side of the connecting rod 903; an elastic member is connected between the inner side wall of the hook rod 902 and the side wall of the wire clamping tongue 4 away from the connecting rod 903, and the elastic member adopts a high-strength spring. In order to achieve better positioning and limiting, in a preferred embodiment, a limiting portion 7 is provided on the inner wall of the connecting rod 903, and a limiting rod is provided on the end of the wire clamping tongue 4 away from the hook rod 902, and the end of the limiting rod abuts against the limiting portion 7 of the connecting rod 903; the pressure sensor 6 is pasted under the limiting portion 7, and the space between the lower part of the limiting rod of the wire clamping tongue 4 and the pasting position of the pressure sensor 6 is used to clamp the grounding wire, and a wiring groove 5 is provided on the inner wall of the connecting rod 903 between the limiting portion 7 and the placement bin 2, and the cable of the pressure sensor 6 is arranged in the wiring groove 5, and the end of the cable is passed into the placement bin 2 and connected with the single-chip microcomputer.

[0035] In order to make the clamping force stronger and avoid unstable clamping of the grounding wire, the hook rod 902 is provided with a first positioning hole 10 and a second positioning hole 11 in this embodiment; one end of the wire clamping tongue 4 is hinged in the second positioning hole 11 through an aluminum rod, and a spring is provided in the first positioning hole 10, and the end of the spring abuts against the side wall of the wire clamping tongue 4 away from the connecting rod 903. The wire clamping tongue 4 is squeezed by the elastic force of the spring, so that the end of the limiting rod of the wire clamping tongue 4 abuts against the limiting part 7 of the connecting rod 903, so that the grounding wire can be firmly clamped between the wire clamping tongue 4 and the connecting rod 903. Since the side wall of the connecting rod 903 is provided with a wiring hole 12, the outside of the wiring hole 12 is connected to a grounding lead through a rivet, and the end of the grounding lead is connected to a grounding nail, and the grounding nail is connected to the ground; the grounding wire is electrically connected to the wiring hole 12 through the wire clamping tongue 4, thereby realizing the hanging of the grounding wire, and the grounding nail is connected to the ground, and the electricity is led underground to ensure the safety of the staff.

[0036] The use process of the grounding wire lacks effective monitoring. Once the grounding wire is out of the warehouse for use, the management personnel often have no idea about its subsequent use, and it is difficult for the management personnel to understand the status of the grounding wire in real time. In order to solve this problem, in one embodiment of the present invention, the placement bin 2 is divided into three layers, the bottom layer of the placement bin 2 is used to place the rechargeable battery, and the middle layer of the placement bin 2 is used to place the single-chip microcomputer. The single-chip microcomputer serves as the control center of the system and is responsible for coordinating the data interaction and processing between the modules to ensure the real-time and accuracy of the data. Through the built-in storage module of the single-chip microcomputer, the key information such as the use time, number of uses, and specific location of each hookup of the grounding wire can be recorded in detail, providing data support for the regular maintenance, inspection and performance evaluation of the equipment. These data are centrally managed through the cloud server, and the operators can access and download them at any time, providing a scientific basis for optimizing the operation process and improving the operation efficiency. The top layer of the placement warehouse 2 is used to place the 4G wireless communication module, the GPS+Beidou dual-mode positioning module and the attitude sensor. The 4G wireless communication module uses the high-speed and stable mobile communication network to upload the collected pressure, attitude and positioning data to the cloud server in real time, realizing remote transmission and real-time monitoring of data. The GPS+Beidou dual-mode positioning module ensures the accurate positioning of the device on a global scale, and provides precise location information for subsequent maintenance and management; the top layer of the placement warehouse 2 is installed with a warehouse cover 8, and a drill hole is provided above the warehouse cover 8, and an antenna is penetrated in the drill hole; the data of the attitude sensor, the pressure sensor 6 and the GPS+Beidou dual-mode positioning module are all uploaded to the cloud server through the 4G wireless communication module; after receiving the data, the cloud server can perform visualization processing and send the data to the mobile terminal for visualization display.

[0037] In this embodiment, except for the pressure sensor 6, the other modules communicate with the single-chip microcomputer through the serial port, and the stability is good. Figure 6As shown in the figure, all module data is uploaded to the cloud platform through the 4G wireless communication module. The server receives the data and performs visualization processing. The cloud platform has four known main systems and other known small module systems. The main systems are intelligent storage and warehousing system, intelligent positioning system, intelligent alarm system and command issuing system. The other small module systems enable the cloud server to see the data of all grounding wire products, including whether they are correctly hung and their posture. The data can be sent to the mobile terminal, where the device usage can be directly viewed. The command issuing function of the cloud platform can issue instructions to the grounding wire system on the cloud platform or the mobile terminal, and notify the staff in time when there is a missing hang or not hanging firmly. The GPS+Beidou dual-mode positioning module obtains GPS information through the antenna and sends the data to the single-chip microcomputer through the serial port. The single-chip microcomputer parses the data into longitude and latitude data and sends it to the cloud platform. The location of the grounding wire system can be seen in real time in the cloud server, which is convenient for searching. There is also a barcode structure, which is a mature structure, similar to the commodity barcode. When the grounding wire system is far away from the warehouse, it is determined whether the barcode is scanned for delivery. If the barcode is not scanned, the grounding wire system will be marked in red in the visual interface. At the same time, the cloud platform also has the grounding wire system management and identification function. A special barcode is attached to the cover of the grounding wire system placement bin 2. When taking the grounding wire system from the warehouse for use, it is necessary to scan the barcode for delivery. At this time, the cloud platform will display that it is in use. Similarly, when returning, it is still necessary to scan the barcode for warehousing. Many grounding wire systems can be better managed.

[0038] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
