Description

Technical Field

[0001] This utility model relates to the field of grounding device technology, and more specifically, to an electrical grounding rod and device. Background Technology

[0002] Electrical grounding devices safely conduct fault currents or lightning strike energy to the earth through low-impedance conductors, protecting equipment and personnel. The resistance value of the grounding rod is a key parameter for evaluating its conductivity. Under extreme conditions such as lightning strikes or short circuits, the grounding rod may experience localized abnormal heating, leading to melting, insulation failure, or even fire. Traditional grounding rods typically use fixed temperature sensors for single-point temperature measurement. However, under extreme conditions, the heating of the grounding rod is usually uneven, making it difficult to fully reflect the overall temperature distribution. This may delay the detection and early warning of abnormal temperature rises, affecting the timeliness of emergency response. Utility Model Content

The drive unit is used to drive the winding disc to rotate in a direction perpendicular to the axial direction. The lifting rope is wound on the winding disc, and the free end of the lifting rope passes through the sliding groove and is connected to the temperature detection component.

[0011] In an optional embodiment, the temperature detection assembly further includes a guide wheel disposed within the insulation chamber and between the lifting rope and the sliding groove, wherein the free end of the lifting rope passes through the guide wheel and is inserted into the sliding groove.

At the same time, the temperature of the grounding rod body can be detected by a temperature sensing element. Since the grounding rod body is provided with a sliding groove that extends axially to all points along the axial direction of the grounding rod body, a driving element is used to drive the temperature sensing element to slide axially within the sliding groove. Thus, when the driving element drives the temperature sensing element to slide axially within the sliding groove, the temperature sensing element can reciprocate along the axial direction of the grounding rod body to detect the temperature at various points on the grounding rod body in real time. In this way, the overall temperature distribution of the grounding rod body can be fully reflected, improving the timeliness of emergency response. Attached Figure Description

[0037] Reference Figure 1 as well as Figure 2 As shown, the electrical grounding rod involved in the embodiment of this application has an axial direction x, and the electrical grounding rod includes: a grounding rod body 100 and a temperature detection component 200.

[0038] Specifically, the grounding rod body 100 is provided with a sliding groove 110, which extends along the axial direction x to various points along the axial direction of the grounding rod body 100; the temperature detection assembly 200 includes a driving member 210 and a temperature detection member 220. The temperature detection member 220 is disposed in the sliding groove 110 and is slidably connected to the groove wall of the sliding groove 110. The driving member 210 is connected to the temperature detection member 220 and is used to drive the temperature detection member 220 to slide along the axial direction x in the sliding groove 110.

[0039] It should be noted that the axial direction x is Figure 1 The direction indicated by x in the middle.

[0040] In the electrical grounding rod of this application, the grounding rod body 100 is used for grounding to safely conduct fault current or lightning energy into the earth through a low-impedance conductor. At the same time, the temperature of the grounding rod body 100 can be detected by a temperature detection element 220. Since the grounding rod body 100 is provided with a sliding groove 110, which extends along the axial direction x to all points along the axial direction of the grounding rod body 100, the driving element 210 is used to drive the temperature detection element 220 to slide along the axial direction x in the sliding groove 110. Thus, when the driving element 210 drives the temperature detection element 220 to slide along the axial direction x in the sliding groove 110, the temperature detection element 220 can reciprocate along the axial direction of the grounding rod body 100 to detect the temperature at all points of the grounding rod body 100 in real time. In this way, the overall temperature distribution of the grounding rod body 100 can be fully reflected, improving the timeliness of emergency response.

[0041] Reference Figure 2 as well as Figure 4 As shown, the temperature detection component 200 also includes a guide rail 230 and a slider 240. The guide rail 230 is connected to the groove wall of the sliding groove 110 and extends along the axial direction x. The slider 240 is connected to the temperature detection component 220 and is slidably connected to the guide rail 230, and slides relative to the guide rail 230 along the axial direction x.

[0042] In this embodiment, since the slider 240 is slidably connected to the guide rail 230 and slides relative to the guide rail 230 in the axial direction x, when the driving member 210 drives the temperature detection member 220 to move axially, the slider 240 can slide relative to the guide rail 230 in the axial direction. The slider 240 and the guide rail 230 cooperate to guide the movement of the temperature detection member 220, ensuring that the temperature detection member 220 can slide in the axial direction x. At the same time, the sliding of the slider 240 relative to the guide rail 230 can also improve the smoothness of the sliding of the temperature detection member 220 in the axial direction x, thereby improving the operational stability of the temperature detection assembly 200.

[0043] Reference Figure 2 As shown, the grounding rod body 100 has a rod body portion 120 and an insulating portion 130. A sliding groove 110 is formed on the rod body portion 120. The insulating portion 130 is disposed on the groove wall of the sliding groove 110 and extends along the axial direction x. A guide rail 230 is disposed on the insulating portion 130.

[0044] In this embodiment, the rod body 120 is used for grounding. Since the sliding groove 110 has an insulating part 130 on its groove wall and the guide rail 230 is disposed on the insulating part 130, the temperature detection component 200 can be electrically isolated from the rod body 120 through the insulating part 130. This reduces the probability of current flowing directly into the temperature detection component 220 through the rod body 120, thereby reducing the impact on equipment safety and the accuracy of measurement data. At the same time, the insulating part 130 also provides a mounting base for the guide rail 230, so that the guide rail 230 can be connected to the grounding rod body 100, thereby improving the operational stability of the temperature detection component 200. Furthermore, under extreme operating conditions, if the temperature detection component 200 fails, it may lead to an unexpected electrical connection. The insulating part 130 can reduce the probability of short circuit and improve the safety of the entire electrical grounding device.

[0045] Reference Figure 5 As shown, the grounding rod body 100 also has a grounding part 140, which is located at one end of the rod body 120 along the axial direction x. In the axial direction x, the projection of the grounding part 140 on the rod body 120 gradually decreases in the direction away from the rod body 120. A spiral groove 121 is provided on the surface of the rod body 120 near the grounding part 140.

[0046] In this embodiment, the grounding part 140 is used for grounding. In the axial direction x, since the projection of the grounding part 140 on the rod part 120 gradually decreases in the direction away from the rod part 120, the grounding part 140 can be made into a cone shape, and the cone apex of the grounding part 140 is located at its end away from the rod part 120, so that the grounding rod body 100 can be inserted into the soil, thereby improving the grounding stability of the grounding part 140. At the same time, since the surface of the rod part 120 near the grounding part 140 is provided with a spiral groove 121, the friction coefficient between the grounding rod body 100 and the soil can be increased, thereby further improving the grounding stability of the electrical grounding rod.

[0047] Reference Figure 1 As shown, the electrical grounding rod also includes a baffle 600, which covers the sliding groove 110.

[0048] In this embodiment, since the baffle 600 covers the sliding groove 110, the sliding groove 110 can be closed by the baffle 600 to provide a closed sliding space, thereby protecting the temperature detection element 220. When the grounding rod body 100 is inserted into the soil, it can prevent soil from entering the interior of the sliding groove 110 and prevent the temperature detection element 220 from being blocked from sliding in the sliding groove 110.

[0049] Reference Figure 2 as well as Figure 3As shown, the electrical grounding rod also includes an insulating chamber 300, which is disposed at one end of the grounding rod body 100 along the axial direction x. The driving component 210 is disposed inside the insulating chamber 300. The interior of the insulating chamber 300 is connected to the sliding groove 110. The temperature detection component 200 also includes a winding disc 250 and a lifting rope 260. The winding disc 250 is disposed inside the insulating chamber 300 and is connected to the output end of the driving component 210. The driving component 210 is used to drive the winding disc 250 to rotate in a direction perpendicular to the axial direction x. The lifting rope 260 is wound on the winding disc 250, and the free end of the lifting rope 260 passes through the sliding groove 110 and is connected to the temperature detection component 220.

[0050] In this embodiment, since the driving component 210 is housed within the insulating chamber 300, the insulating chamber 300 electrically isolates the driving component 210 from the grounding rod body 100, reducing the possibility of short circuits and improving the safety performance of the electrical grounding rod. The insulating chamber 300 not only provides electrical isolation but also offers a closed protective space for the driving component 210, the winding reel 250, and the lifting rope 260, reducing the corrosion or damage to the driving component 210 caused by external environmental factors and extending the service life of the temperature detection component 200. Service life; furthermore, since the lifting rope 260 is wound on the winding disc 250, and the free end of the lifting rope 260 passes through the sliding groove 110 and is connected to the temperature detection element 220, the driving element 210 is used to drive the winding disc 250 to rotate in a direction perpendicular to the axial direction x. Thus, when the driving element 210 drives the winding disc 250 to rotate, the lifting rope 260 wound on the winding disc 250 can be raised and lowered in the axial direction x, thereby driving the temperature detection element 220 so that the temperature detection element 220 can move in the axial direction x.

[0051] Reference Figure 2 As shown, the temperature detection component 200 also includes a guide wheel 270, which is disposed inside the insulation chamber 300 and between the lifting rope 260 and the sliding groove 110. The free end of the lifting rope 260 passes through the guide wheel 270 and is disposed inside the sliding groove 110.

[0052] In this embodiment, the guide wheel 270 can guide the movement of the lifting rope 260 to ensure that the lifting rope 260 can move in the axial direction x under the action of the guide wheel 270. At the same time, the guide wheel 270 can also tension the lifting rope 260 to reduce the possibility of direct contact between the lifting rope 260 and the grounding rod body 100, thereby reducing friction and wear between the lifting rope 260 and the grounding rod body 100. Furthermore, the guide wheel 270 can also improve the uniformity of force on the temperature detection component 200, so as to balance the force of the temperature detection component 220 on the winding disc 250 and the grounding rod body 100, thereby improving the movement stability of the lifting rope 260.

[0053] Specifically, refer to Figure 4 As shown, in this embodiment, the temperature detection element 220 includes an electrical part 221 and a temperature detection part 222. The electrical part 221 is connected to the lifting rope 260. At least part of the surface of the sliding groove 110 is not covered by the insulating part 130. The temperature detection part 222 is connected to the electrical part 221 and is electrically connected to the electrical part 221. The temperature detection part 222 is disposed near the surface of the sliding groove 110 that is not covered by the insulating part 130 so as to monitor the temperature of various parts of the grounding rod body 100 in real time. At the same time, the electrical part 221 supplies power to the temperature detection part 222 and receives the temperature signal transmitted by the temperature detection part 222.

[0054] Specifically, in this embodiment, the temperature detection unit 222 is a non-contact temperature sensor. The non-contact temperature sensor does not need to directly contact the grounding rod body 100, thus avoiding heat transfer or interference that may be caused by contact with the grounding rod body 100. This characteristic is particularly suitable for temperature measurement in high temperature, low temperature, corrosive environments or dangerous areas. At the same time, non-contact sensors can usually complete temperature measurement quickly. This fast response characteristic can meet the requirements for dynamic detection of the grounding rod body 100 during movement.

[0055] Reference Figure 3 As shown, the electrical grounding rod also includes an electrical connection assembly 400 and a conductive element 500. One end of the conductive element 500 is connected to the grounding rod body 100, and the other end of the conductive element 500 is connected to the electrical connection assembly 400. The electrical connection assembly 400 is used to connect to an external wire.

[0056] Specifically, refer to Figure 3As shown, one end of the conductive element 500 is located inside the insulating chamber 300 and connected to the grounding rod body 100, while the other end of the conductive element 500 is exposed outside the insulating chamber 300 and connected to the electrical connection assembly 400. The insulating chamber 300 has a chamber body 310 and multiple cover plates 320. The chamber body 310 is connected to the grounding rod body 100, and the interior of the chamber body 310 communicates with the sliding groove 110 and is used for the conductive element 500 to pass through. The multiple cover plates 320 are arranged around the conductive element 500, and the multiple cover plates 320 are combined to form a cover over the chamber body 310. The cover plate at the end away from the grounding rod body 100 along the axial direction x can be detachably connected between any two adjacent cover plate portions 320, so as to connect the conductive component 500 to the grounding rod body 100. At the same time, it is convenient to quickly disassemble and reinstall the internal structure of the insulation chamber 300 when needed, so as to facilitate the inspection, maintenance or replacement of the internal structure of the insulation chamber 300. Meanwhile, multiple cover plate portions 320 together cover the chamber portion 310 to prevent external environmental factors from entering the interior of the insulation chamber 300 and protect the internal structure of the insulation chamber 300.

[0057] In this embodiment, the electrical connection component 400 and the grounding rod body 100 can be electrically connected through the conductive component 500, and the external wire can be electrically connected to the grounding rod body 100 through the electrical connection component 400.

[0058] Continue to refer to Figure 3 As shown, the electrical connection assembly 400 includes a first electrical connector 410, a second electrical connector 420, a bolt 430, and a nut 440. The bolt 430 is connected to the second electrical connector 420. The first electrical connector 410 has a connection hole (not shown). The bolt 430 passes through the connection hole and protrudes at least partially from the end of the connection hole away from the second electrical connector 420. The nut 440 is threadedly connected to the portion of the bolt 430 protruding from the connection hole and abuts against the end of the first electrical connector 410 away from the second electrical connector 420. The second electrical connector 420 is at least partially spaced from the first electrical connector 410 to define a clamping space 450 between the first electrical connector 410 and the second electrical connector 420.

[0059] In this embodiment, the external wire can be clamped in the clamping space 450. During this process, the bolt 430 can be inserted into the connection hole to connect the first electrical connector 410 and the second electrical connector 420. Since the nut 440 and the bolt 430 are threadedly connected to the part protruding from the connection hole and abut against the end of the first electrical connector 410 away from the second electrical connector 420, the first electrical connector 410 and the second electrical connector 420 can be fixed by the connection of the nut 440 and the bolt 430, thereby realizing the detachable connection of the first electrical connector 410 and the second electrical connector 420. This clamps the external wire in the clamping space 450 and facilitates the installation and removal of the external wire, improving the convenience of installation and removal.

[0060] Specifically, in this embodiment, the first electrical connector 410 is a conductive strip, and the second electrical connector 420 is a U-shaped conductive block. When the conductive strip is connected to the U-shaped conductive block, a clamping space 450 can be defined between the conductive strip and the U-shaped conductive block to achieve clamping of the external wire.

[0061] The electrical grounding device involved in the embodiments of this application includes: the above-mentioned electrical grounding rod.

[0062] In the electrical grounding device of this application, since the above-mentioned electrical grounding rod can monitor the temperature at each location in real time, it can fully reflect the overall temperature distribution of the grounding rod body 100, improve the timeliness of emergency response, and make the electrical grounding device of this application have better safety performance.
