Description

Technical Field

[0002] As a safety tool for power production, grounding wires have the advantages of low cost, simple and reliable principles, and convenient operation. They are widely used in the maintenance of power equipment to provide grounding protection for maintenance equipment or lines to prevent personal injury and equipment damage caused by unexpected calls. Both the hanging and removal operations require manual intervention, and it is easy for the grounding rod of the grounding wire to be missed, hung incorrectly, or poorly hung. Some existing intelligent grounding wires use pressure sensors or micro-motion sensors to determine whether the grounding rod is hung on the line, but they cannot detect whether the grounding rod is hung on the bare wire of the line or outside the insulation layer of the line. If it is mistakenly hung outside the insulation layer, a major safety accident will occur. Therefore, there is an urgent need for an intelligent grounding wire device that can monitor whether the grounding rod is securely hung on the bare wire of the line. Summary of the invention

[0011] The beneficial effects of the present invention are as follows:

[0012] The present invention arranges a conductive rod on the front side of the clamping hook tongue, and arranges an input end of a hooking detection circuit to electrically connect the conductive rod and the hook body, so that after the bare wire is hooked in place, the bare wire is in close contact with the hook body and the conductive rod, and the hooking detection circuit forms an electrical connection loop.

[0014] The slave circuit board and battery of the present invention are arranged inside the insulating rod, rather than outside the hook body or the insulating rod, which can reduce the volume of the product and eliminate the need to worry about collision and damage to components during transportation;

The conductive rod clamped on the vertical section of the L-shaped bracket protrudes from the L-shaped bracket and is located in front of the clamping hook tongue. When the line is in the process of opening the clamping hook tongue, the L-shaped bracket can be squeezed to rotate. The L-shaped bracket will not block the line. After the clamping hook tongue is clamped and hung in place, the bare wire can be tightly in contact with the conductive rod, avoiding the situation where the bare wire is hung in place, but the conductive rod fails to contact the bare wire, resulting in a false alarm.

[0016] By designing the conductive rod as a U-shaped rod and clamping it in the U-shaped mounting hole of the L-shaped bracket, it can be ensured that the conductive rod will not fall off the L-shaped bracket when the line is hung or removed, and the conductive rod is easy to replace after being worn, and only the conductive rod, which is a relatively low-cost part, needs to be replaced;

[0017] By arranging a threading hole and a first wire hole on the hook body, and arranging a second wire hole and a third wire hole on the insulating bracket, the wires connected to the hook body and the conductive rod can pass through the inside of the hook body and be introduced into the circuit board inside the insulating rod through the third wire hole on the insulating bracket. This can reduce the exposure of the wire to the outside, thereby increasing the life of the wire and making the product appearance more beautiful. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings 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 should fall within the scope of protection of the present invention.

[0033] Please refer to Figure 1-10The embodiment of the present invention provides an intelligent grounding wire device, including a grounding rod, a grounding nail and a soft copper wire connecting the grounding rod and the grounding nail, the grounding rod includes a conductive hook body 1 and an insulating rod 2 connected to the lower end of the hook body 1, two wire clamping hook tongues 3 facing each other are arranged on the inner side of the hook body 1, a slave circuit board 4 and a battery 5 are arranged in the insulating rod 2, a single-chip microcomputer, a hanging detection circuit electrically connected to the single-chip microcomputer, and a wireless communication module are arranged on the slave circuit board 4, the single-chip microcomputer is connected to a host computer arranged on the upper part of the grounding nail through the wireless communication module, the host computer includes a display module for displaying the hanging state, an insulating arc cover 6 matching the front side of the hook body 1 is covered on the front side of the hook body 1, a notch is arranged on the side wall of the arc cover 6 close to the wire clamping hook tongue 3, a limit portion 7 is arranged on the inner side wall of the arc cover above the notch, an insulating L-shaped bracket 8 is arranged in the arc cover 6, and the bottom of the vertical section of the L-shaped bracket 8 is hinged to the arc cover 6, a limiting tongue 9 is provided at the end of the horizontal section of the L-shaped bracket 8, which is in contact with the limiting part 7. The middle part of the vertical section of the L-shaped bracket 8 is connected to the arc cover 6 by an elastic member 21. The limiting tongue 9 and the limiting part 7 are tightly fitted under the elastic force of the elastic member 21. The corner part of the L-shaped bracket 8 extends from the notch of the arc cover 6 to the front side of the wire clamping hook tongue 3. A conductive rod 10 is clamped on the corner part of the L-shaped bracket 8. The conductive rod 10 clamped on the vertical section of the L-shaped bracket 8 protrudes from the L-shaped bracket 8. One end of the conductive rod 10 is electrically connected to an input end of the hanging detection circuit, and the hook body 1 is electrically connected to the other input end of the hanging detection circuit. When the hook body 1 is hung to the bare wire, the bare wire is in close contact with the hook body 1 and the conductive rod 10, and the hanging detection circuit forms an electrical connection loop. The single-chip microcomputer receives the low level input by the hanging detection circuit, and the single-chip microcomputer determines that the grounding rod has been hung and sends the hanging status to the host.

[0034] When using the intelligent grounding wire device of the present invention, first insert the grounding nail connected to the soft copper wire into the ground and fix it, and the host is fixed to the grip rod above the grounding nail by a claw. The host is provided with a ground penetration depth sensor, which can detect whether the grounding nail is inserted into the ground to meet the standard. Then the grounding rod connected to the soft copper wire is hung on the line, and the line is stretched open and clamped by the wire clamping hook tongue 3. Because the middle part of the vertical section of the L-shaped bracket 8 is connected to the arc cover 6 by an elastic member, the conductive rod 10 clamped on the vertical section of the L-shaped bracket 8 protrudes from the L-shaped bracket 8 and is located on the front side of the wire clamping hook tongue 3. Therefore, in the process of stretching the wire clamping hook tongue, the L-shaped bracket 8 is squeezed to rotate, and after the wire clamping hook tongue 3 is clamped and hung in place, the line will be in tight contact with the conductive rod 10. If the grounding rod is hung on the bare wire part of the line, the hanging detection circuit forms an electrical connection loop, and the single-chip microcomputer receives the low level input by the hanging detection circuit. The single-chip microcomputer determines that the grounding rod is hung. If the grounding rod is hung on the insulating layer part of the line, the hanging detection circuit will not form an electrical connection loop. At this time, the single-chip microcomputer receives the high level input by the hanging detection circuit. The single-chip microcomputer determines that the hanging state of the grounding rod is a hanging failure, and sends the hanging state to the host. The display module of the host displays the hanging state, and the display module specifically includes a display screen. At the same time, the host can also send the connection status to the cloud platform through the wireless network communication module set inside it to achieve remote supervision. The intelligent grounding wire device of the present invention is provided with three grounding rods corresponding to the three-phase line, and each grounding rod is provided with a slave machine for respectively detecting the connection status of each grounding rod, and the slave machine is arranged inside the insulating rod.

[0035] In order to further ensure that when the hook body 1 is reliably hooked to the bare wire, the conductive rod 10 is in close contact with the bare wire, and in the process of hooking and removing, the conductive rod 10 will not be separated from the L-shaped bracket 8, the conductive rod 10 used in the embodiment of the present invention is a U-shaped rod, and a mounting through hole 11 is provided near the corner portion of the horizontal section and the vertical section of the L-shaped bracket 8, and the axes of the two mounting through holes 11 are parallel. An L-shaped mounting groove 12 is provided at the corner portion of the L-shaped bracket 8, and the two ends of the mounting groove 12 are respectively connected with the two mounting through holes 11 to form a U-shaped mounting hole groove. The conductive rod 10 is clamped in the U-shaped mounting hole groove, and one end of the conductive rod passes through the mounting through hole 11 corresponding to it and extends to the L The outside of the L-shaped bracket 8 is electrically connected to an input end of the hanging detection circuit through a wire. The conductive rod 10 in the installation groove 12 on the vertical section of the L-shaped bracket 8 protrudes from the L-shaped bracket 8 to form a detection contact. The detection contact is located on the left side or in front of the gap between the two wire clamping hook tongues 3, and at the same time, the height is higher than the height of the minimum part of the gap distance between the two wire clamping hook tongues. The conductive rod of the above structure, the installation method and the installation position of the conductive rod can ensure that the conductive rod will not fall off from the L-shaped bracket when hanging or removing the line, and the conductive rod is easy to replace after wear. At the same time, it is ensured that after being hung in place, the conductive rod 10 is in close contact with the bare wire and no false detection will occur.

[0036] like Fig.11As shown, the hook detection circuit specifically adopted in the embodiment of the present invention includes a bidirectional TVS tube D11, one end of the bidirectional TVS tube D11 is grounded, the other end of the bidirectional TVS tube D11 is connected in series with the input end of the optocoupler and the resistor R71 in sequence and then connected to a 5V power supply, a welding point H21 is left at the grounded end of the bidirectional TVS tube D11, after a wire is welded to the welding point H21, the other end of the wire is electrically connected to the hook body 1, a welding point H20 is left at the end of the bidirectional TVS tube D11 connected to the optocoupler U13, after a wire is welded to the welding point H20, the other end of the wire is electrically connected to the conductive rod 10, the emitter of the output transistor of the optocoupler U13 is grounded, the collector of the output transistor of the optocoupler U13 is connected in series with the resistor R72 and then connected to the 3.3V power supply, and the input pin LINE of the single-chip microcomputer is connected to the collector of the output transistor of the optocoupler U13 after passing through the resistor R73. When the hook body 1 is reliably hooked to the bare wire, for the hook detection circuit, it is equivalent to H21 and H20 being connected through the wire. At this time, the electrical signal is sent to the input end of the optocoupler U13, the light-emitting diode emits light through the current, the photosensitive element generates current after being illuminated by light, the collector and emitter of the output transistor of the optocoupler U13 are turned on, and the 3.3V voltage flows to PGND after passing through the components. The voltage input to the input pin LINE of the single-chip microcomputer is lower than 3.3 V, which is a low level. If it is not hooked to the bare wire of the line, H21 and H20 are disconnected, and the voltage input to the input pin LINE of the single-chip microcomputer is 3.3V, which is a high level. Because the detection circuit is electrically connected to the hook body and conductive rod of the peripheral that may come into contact with people, in order to prevent static electricity from entering the circuit and breaking down the components, a bidirectional TVS tube is set to protect the subsequent components from forward and reverse overvoltage.

[0037] In some embodiments, the slave circuit board 4 is further provided with a posture detection module and a first air pressure detection module, and the host further includes a second air pressure detection module. The input end of the posture detection module is electrically connected to the gyroscope chip, and the output ends of the first air pressure detection module and the posture detection module are both electrically connected to the single-chip microcomputer. The installation orientation of the gyroscope chip on the slave circuit board is that the positive direction of the X-axis of the gyroscope chip points to the hook direction of the grounding rod. The single-chip microcomputer receives the pitch angle data output by the gyroscope chip, and judges the posture of the grounding rod according to the pitch angle data. The first air pressure detection module is used to obtain the height of the grounding rod, and the second air pressure detection module is used to obtain the ground height and send the ground height data to the calculation module of the host. The single-chip microcomputer sends the obtained grounding rod height data and grounding rod posture information to the host. The host's calculation module combines the grounding rod hanging state, the grounding rod height data, the ground height data and the grounding rod posture information to judge whether the grounding rod has fallen and the risk of falling. The host sends the grounding rod posture information, whether it has fallen, the risk of falling and the grounding rod hanging state to the cloud platform through the wireless network communication module.

[0038] The gyroscope chip model used in the embodiment of the present invention is MPU6050. Fig.12 As shown in the figure, the schematic diagram of the MPU6050 three-axis angle, pitch is the pitch angle, roll is the roll angle, and yaw is the heading angle. The attitude of the ground rod is determined only by the pitch angle. The determination rules are as follows:

[0039] Pitch Angle Ground rod posture -10° to +10° Horizontal -45° to -10° or +10° to +45° tilt -90° to -45° Vertical 45° to 90° Invert

[0040] The computing module of the host combines the ground rod hanging state, ground rod height data, ground height data and ground rod posture information to determine whether the ground rod has fallen and the risk of falling. The specific process includes: if the ground rod hanging state is not hung, the height data of the ground rod from the ground is calculated by the difference between the ground rod height data and the ground height data, and the data is compared with the preset height difference interval. If it exceeds the preset height difference interval, the posture of the ground rod is judged. If it is not in a vertical state, it proves that the ground rod has fallen. If the posture of the ground rod is tilted within a certain period of time, the difference between the ground rod height data and the ground height data is within the preset height difference interval, and the hanging state is hung, it proves that there is a strong wind. The ground rod is tilted by the strong wind. The host determines that there is a risk of falling. It is necessary to pay special attention to whether a fall occurs, and a fall risk prompt is issued on the cloud platform. If the ground rod attachment status is not attached, but the difference between the ground rod height data and the ground height data is within the preset height difference range, the host determines that the ground rod is not attached because the attachment is not secure and not properly attached. It can be seen that the host calculation module can be used to determine multiple reasons why the ground rod is not attached successfully, and help the staff to find out the reasons why the ground rod is not attached successfully.
