Description

Technical Field

[0001] The present invention relates to the technical field of grounding wire structures, and in particular to a grounding wire structure and an intelligent detection device thereof. Background Art

[0002] The existing grounding wire structures are divided into natural grounding wires and artificial grounding wires.

[0003] General natural grounding wires include but are not limited to: (1) Metal structures of buildings, such as beams and columns, can be used as grounding wires, but they must be reliably connected along the entire length to form a continuous conductor.

[0004] (2) Metal structures such as crane rails and power distribution equipment frames used in production can also be used as grounding wires.

[0005] (3) The steel pipe used for wiring is also a good grounding wire, but its wall thickness should not be less than 1.5 mm to avoid rust and become a discontinuous conductor.

[0006] Artificial grounding wires generally need to use grounding wires of different specifications according to the use environment. The existing grounding wire structure generally includes grounding wire clamps, grounding rods, grounding clips and grounding wires. The grounding rods are pre-buried underground and connected to the electrical equipment that needs to be grounded through structures such as grounding clips and grounding wire clamps, thereby achieving the purpose of grounding.

[0007] In order to facilitate installation, the grounding wire clamps and grounding clips in the existing grounding wire structure generally adopt a press-fitting method to electrically connect the grounding wire to the grounding rod and the electrical equipment. Due to the complex use environment, the grounding wire and the grounding rod may become loose after long-term use by only using the press-fitting method, thereby affecting the connection stability between the grounding wire and the grounding rod, thereby causing the grounding loop to be disconnected, and the grounding function cannot be performed normally, which may pose a safety hazard. Summary of the invention

[0008] In order to solve the above technical problems, the object of the present invention is to provide a grounding wire structure and an intelligent detection device thereof that can monitor in real time whether the grounding line connection is stable.

[0009] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: a grounding wire structure, including a connecting body, a pressure-sensitive connecting piece, a first grounding wire, a second grounding wire and a grounding rod, the pressure-sensitive connecting piece is arranged on the connecting body, one end of the first grounding wire is connected to the electrical equipment through a grounding clip, and the other end thereof is connected to the connecting body through a pressure-sensitive connecting piece, one end of the second grounding wire is connected to the connecting body through a pressure-sensitive connecting piece, and the other end thereof is connected to the grounding rod.

[0010] The beneficial effect of the present invention is that when the second grounding wire is connected to the grounding wire structure and press-fitted, the pressure at the connection point of the second grounding wire is detected in real time by the pressure-sensing connector, so as to judge the tightness of the press-fitting, thereby improving the safety of the device when in use.

[0011] Based on the above technical solution, the present invention can also be improved as follows.

[0012] Furthermore, a strip groove is opened at the upper end of the connection body, the pressure-sensitive connection member is arranged in the strip groove, a cover plate is rotatably connected to the inner wall of the upper end of the strip groove, and a sealing member matching the shape of the cover plate is provided on the inner wall of the strip groove.

[0013] The above technical solution can reduce the interference caused by changes in the external environment to the pressure-sensing connector during use by arranging the pressure-sensing connector inside the strip groove and covering and sealing the strip groove with a seal.

[0014] Furthermore, the number of the pressure-sensing connecting parts is one or more groups, the number of the first grounding wire, the second grounding wire and the grounding rod is one or more, and the connecting body is provided with LED indicator lights corresponding to the pressure-sensing connecting parts one by one below the strip groove.

[0015] The above technical solution can adjust the device according to specific usage conditions by setting the number of pressure-sensitive connectors to one or more groups and correspondingly setting the number of first grounding wires, second grounding wires and grounding rods to one or more groups, thereby improving the overall adaptability of the device.

[0016] Furthermore, the sealing member is a rubber strip, the cross-section of the rubber strip is a trapezoid, and the height of one side of the rubber strip away from the cover plate is greater than the height of the other side.

[0017] The above technical solution can improve the airtightness of the device at the pressure-sensitive connector by setting a strip of rubber strip. When the cover is closed, the rubber strip is squeezed to deform, and the elastic force generated by the deformation is used to seal the gap between the cover and the rubber strip.

[0018] Furthermore, the pressure-sensing connecting part includes a connecting ring, a metal connecting sheet, a pressure sensing sheet, a connecting stud, a conductive metal ring, a connecting metal sleeve and a nut. One side of the connecting ring is fixedly assembled on the inner wall of the strip groove, and one side of the metal connecting sheet is fixedly assembled on the other side of the connecting ring. The metal connecting sheet is provided with a through hole, and the pressure sensing sheet is arranged at the through hole and is connected and fixed to the connecting ring. One end of the connecting stud passes through the connecting ring and is fixedly assembled on the inner wall of the strip groove, and the other end passes through the conductive metal ring. The nut is threadedly screwed on the other end of the connecting stud, and the upper end of the connecting metal sleeve is fixedly assembled on the lower end of the conductive metal ring.

[0019] The above technical solution presses the conductive metal ring onto the metal connecting sheet by press-fitting, and uses a pressure sensing sheet to monitor the pressure during press-fitting in real time to detect the stability of the press-fitting, thereby improving the safety of the device.

[0020] Furthermore, the lower end of the connecting metal sleeve is connected and fixed to one end of the second grounding wire, and the other end of the first grounding wire passes through the connecting ring and is connected and fixed to one side of the metal connecting sheet.

[0021] The above technical solution sets the second grounding wire and the first grounding wire so that the current of the electrical equipment can be led into the ground through the first grounding wire, the connecting body and the second grounding wire in sequence and finally through the grounding rod.

[0022] Furthermore, rectangular grooves are provided on both sides of the upper end of the connecting body, and fixing screw holes are provided inside the rectangular grooves and pass through the rectangular grooves from front to back.

[0023] The above technical solution provides fixing screw holes and uses bolts to fix the connecting body, and the fixing surface can be selected according to the actual working conditions, thereby improving the convenience of use of the device.

[0024] A second object of the present invention is to provide an intelligent detection device that can adapt to the grounding wire structure and monitor its connection status in real time.

[0025] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: an intelligent detection device includes a grounding wire structure.

[0026] Furthermore, it also includes a remote communication unit, a power supply module and a control module, and the power supply module is electrically connected to the LED indicator light, the remote communication unit, the control module and the pressure sensing sheet.

[0027] The above technical solution transmits the signal of the pressure-sensitive connector to the remote terminal in real time by setting up a remote communication unit, and uses its internal independent power supply module and control module to power and control the electronic components inside the connection body.

[0034] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention. Example

[0035] like Figure 1-4 As shown, a grounding wire structure includes a connecting body 1, a pressure-sensitive connecting member 2, a first grounding wire 5, a second grounding wire 3 and a grounding rod 4. The pressure-sensitive connecting member 2 is arranged on the connecting body 1. One end of the first grounding wire 5 is connected to the electrical equipment through a grounding clip, and the other end thereof is connected to the connecting body 1 through the pressure-sensitive connecting member 2. One end of the second grounding wire 3 is connected to the connecting body 1 through the pressure-sensitive connecting member 2, and the other end thereof is connected to the grounding rod 4.

[0036] The working principle is: when the connection between the connecting body 1 and the second grounding wire 3 becomes loose, the pressure-sensing connector 2 can detect the stability of the press-fitting by sensing the pressure change during press-fitting, thereby improving the safety of the device when grounding electrical equipment.

[0037] The above technical solution can detect the connection point pressure of the second grounding wire 3 in real time through the pressure-sensing connector 2 when the second grounding wire 3 is connected to the grounding wire structure and pressed, so as to judge the tightness of the press-fitting, thereby improving the safety of the device when in use.

[0038] Preferably, a strip groove is opened at the upper end of the connection body 1, the pressure-sensing connector 2 is arranged in the strip groove, a cover plate 7 is rotatably connected to the inner wall of the upper end of the strip groove, and a sealing member 6 matching the shape of the cover plate 7 is provided on the inner wall of the strip groove.

[0039] The working principle is: when assembling and using the device, the cover plate 7 is turned over and snapped onto the strip groove. At this time, the edge of the cover plate 7 squeezes the seal 6, thereby filling the gap between the cover plate 7 and the strip groove. The cover plate 7 can also protect the internal pressure-sensing connector 2, thereby improving the safety of the device.

[0040] The above technical solution can reduce the interference caused by changes in the external environment to the pressure-sensing connecting member 2 when in use by arranging the pressure-sensing connecting member 2 inside the strip groove and covering and sealing the strip groove with the sealing member 6.

[0041] Preferably, the number of pressure-sensing connectors 2 is one or more groups, the number of first grounding wires 5, second grounding wires 3 and grounding rods 4 is one or more, and the connecting body 1 is provided with LED indicator lights 8 corresponding one-to-one to the pressure-sensing connectors 2 below the strip groove.

[0042] The plurality of LED indicator lights 8 correspond one-to-one to the plurality of pressure-sensitive connecting members 2 and are electrically connected thereto.

[0043] The working principle is: when the pressure-sensing connectors 2 are arranged into multiple groups, the same number of LED indicator lights 8 corresponding to the pressure-sensing connectors 2 are arranged at the lower end of the connecting body 1, and each LED indicator light 8 independently displays the connection status of the corresponding pressure-sensing connector 2, thereby being able to simultaneously detect the conductivity of multiple groups of grounding rods 4.

[0044] The above technical solution can adjust the device according to specific usage conditions by setting the number of pressure-sensing connectors 2 to one or more groups, and correspondingly setting the number of first grounding wires 5, second grounding wires 3 and grounding rods 4 to one or more groups, thereby improving the overall adaptability of the device.

[0045] Preferably, the sealing member 6 is a rubber strip, the cross-section of the rubber strip is a trapezoid, and the height of one side of the rubber strip away from the cover plate 7 is greater than the height of the other side thereof.

[0046] The working principle is: by setting rubber strips with inconsistent heights on both sides, when the cover plate 7 squeezes the rubber strip, it first squeezes the other side of the rubber strip and passes over the other side, causing the rubber strip to deform, and the height of the other side is greater than the height of one side of the rubber strip. Therefore, after passing over and restoring the elastic deformation, it can block the cover plate 7 so that it will not open without external force.

[0047] The above technical solution can improve the airtightness of the device at the pressure-sensing connector 2 by setting a strip of rubber strip, squeezing the rubber strip to deform when the cover 7 is closed, and using the elastic force generated by the deformation to seal the gap between the cover 7 and the rubber strip.

[0048] Preferably, the pressure-sensing connector 2 includes a connecting ring 21, a metal connecting sheet 22, a pressure sensing sheet 23, a connecting stud 24, a conductive metal ring 25, a connecting metal sleeve 27 and a nut 26. One side of the connecting ring 21 is fixedly assembled on the inner wall of the strip groove, one side of the metal connecting sheet 22 is fixedly assembled on the other side of the connecting ring 21, a through hole is provided on the metal connecting sheet 22, the pressure sensing sheet 23 is arranged at the through hole and is connected and fixed to the connecting ring 21, one end of the connecting stud 24 passes through the connecting ring 21 and is fixedly assembled on the inner wall of the strip groove, and the other end passes through the conductive metal ring 25, the nut 26 is threadedly screwed on the other end of the connecting stud 24, and the upper end of the connecting metal sleeve 27 is fixedly assembled on the lower end of the conductive metal ring 25.

[0049] The working principle is: when the conductive metal ring 25 connected to the second grounding wire 3 is pressed onto the metal connecting plate 22, the conductive metal ring 25 generates pressure on the pressure sensing plate 23 at the same time, and the pressure sensing plate 23 can detect its pressure in real time. When looseness occurs, the pressure decreases and the pressure sensing plate moves. At this time, the connection status of the conductive metal ring 25 is converted into a pressure value, and the pressure value is converted into a point signal through the pressure sensing plate for output, so that the device can detect the connection status of the conductive metal ring 25 in real time.

[0050] The above technical solution presses the conductive metal ring 25 onto the metal connecting sheet 22 by press-fitting, and uses the pressure sensing sheet 23 to monitor the pressure during press-fitting in real time to detect the stability of the press-fitting, thereby improving the safety of the device.

[0051] Preferably, the lower end of the connecting metal sleeve 27 is connected and fixed to one end of the second grounding wire 3 , and the other end of the first grounding wire 5 passes through the connecting ring 21 and is connected and fixed to one side of the metal connecting sheet 22 .

[0052] The working principle is: when the conductive metal ring 25 is connected stably, the current of the electrical equipment passes through the first grounding wire 5, the connecting body 1 and the second grounding wire 3 in sequence, and finally passes through

[0053] The above technical solution sets the second grounding wire 3 and the first grounding wire 5 so that the current of the electrical equipment can be introduced into the ground through the first grounding wire 5, the connecting body 1 and the second grounding wire 3 in sequence and finally through the grounding rod 4, thereby improving the safety of the electrical equipment.

[0054] Preferably, rectangular grooves are provided on both sides of the upper end of the connecting body 1, and fixing screw holes are provided inside the rectangular grooves and pass through the rectangular grooves from front to back.

[0055] The working principle is as follows: the device can fix the connecting body 1 at the fixing screw hole by means of bolts according to the actual use environment, thereby improving the convenience of using the device.

[0056] The above technical solution provides fixing screw holes and uses bolts to fix the connection body 1. The fixing surface can be selected according to the actual working conditions, thereby improving the convenience of use of the device.

[0057] A second object of the present invention is to provide an intelligent detection device that can adapt to the grounding wire structure and monitor its connection status in real time.

[0058] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: an intelligent detection device includes a grounding wire structure.
