Description

Technical field

[0001] The present utility model relates to the technical field of earthing terminals, in particular an intelligent earthing terminal with pressure sensing function. Background technology

[0002] In the daily operation and maintenance of power supply systems, the grounding clamp plays a crucial role as a safety device, protecting personnel. Its primary function is to securely connect the grounding conductor to the live conductor during the maintenance of lines or equipment, ensuring an equal potential between the equipment and the grounding point. This effectively prevents personal injury caused by unexpected voltage surges or induced voltages on the line. A grounding clamp typically consists mainly of the clamp body, bolts, nuts, and other key components. In practical use, the operator turns the bolt, which in turn moves the clamping mechanism. This brings the two clamping arms closer together and firmly encircles the live conductor, thus ensuring a secure connection between the grounding conductor and the live conductor.

[0003] Currently widespread conventional grounding clamps are predominantly operated manually. Since operation depends entirely on human strength, and the strength and working habits of individual operators vary, precisely monitoring and controlling the pressure applied to the conductor when tightening the grounding clamp is difficult. Excessive pressure can cause irreversible damage to the conductor or equipment and impair the normal service life of the equipment; conversely, insufficient pressure greatly increases the likelihood of a faulty connection between the clamp and the conductor. Such a faulty connection not only leads to unstable current transmission and malfunctions in electrical equipment, but also prevents the fault current from being properly and quickly diverted to earth in the event of a power grid fault.This poses a significant risk to the safety of the workforce and endangers their physical integrity.

[0004] To precisely control the pressure between the grounding terminal and the conductor, thus preventing damage to the conductor and equipment due to excessive pressure as well as an inadequate connection due to insufficient pressure, and thereby ensuring the stable operation of the power supply system and the personal safety of the operating personnel, we propose an intelligent grounding terminal with pressure sensing function.

[0017] With reference to Fig. 1 - Fig.Section 6 of the utility model provides a technical solution: an intelligent grounding clamp with pressure sensing function, comprising a mounting cylinder 1, characterized in that the mounting cylinder 1 is surrounded externally by a mounting sleeve 20, wherein a third screw 28 is attached between the mounting sleeve 20 and the mounting cylinder 1, wherein a connecting block 2 is fixedly connected to the upper end of the mounting sleeve 20, wherein a mounting cover 4 is fixedly attached to the left side of the connecting block 2, wherein the inner wall of the mounting cover 4 is slidably connected to an insertion piece 18, wherein a mounting clamp 5 is fixedly mounted at the upper end of the insertion piece 18, wherein a clamping arrangement for holding the cable is attached to the mounting cylinder 1, and wherein a test arrangement for pressure sensing is installed on the mounting clamp 5; wherein the test arrangement comprises two groups of mounting covers 3, wherein the two groups of mounting covers 3 are each fixedly attached to the front and rear sides of the mounting clamp 5, wherein the inner wall of the mounting cover 3 is fixedly equipped with a pressure sensor 23, wherein the bottom of the pressure sensor 23 is fixedly connected to a connecting rod 25, wherein the connecting rod 25 is slidably guided through the mounting cover 3, and wherein a pressure block 26 is fixedly attached to the bottom of the connecting rod 25.

[0018] During use, the cable is held by the clamping assembly. During the clamping process, the cable exerts pressure on the pressure block 26. The pressure acting on the pressure block 26 is transmitted via the connecting rod 25 to the pressure sensor 23, allowing the pressure acting on the cable during the clamping process to be detected in real time. As soon as the pressure reaches the appropriate value, the clamping assembly is controlled to cease operation. This precisely controls the pressure between the grounding clamp and the cable to prevent damage to the cable and equipment due to excessive pressure, as well as a poor connection due to insufficient pressure. This ensures the stable operation of the power supply system and the personal safety of the operators.

[0019] The clamping arrangement comprises a screw rod 22, wherein the screw rod 22 is guided through a threaded connecting block 2, wherein a connecting plate 13 is rotatably attached to the top of the screw rod 22, wherein two groups of movable clamping plates 12 are rigidly connected to the top of the connecting plate 13, wherein both groups of movable clamping plates 12 are slidably connected to the mounting clamp 5 on the side facing the mounting clamp 5, and wherein a rotary device for rotating the screw rod 22 is attached to the mounting cylinder 1.

[0020] The rotary device comprises a mounting plate 16, wherein the mounting plate 16 is fixedly connected to the inner wall of the mounting cylinder 1, wherein a motor 15 is fixedly mounted on the top of the mounting plate 16, wherein the output end of the motor 15 is fixedly connected to a rotary cylinder 14, wherein the rotary cylinder 14 is nested on the outside of the screw rod 22, wherein the inner wall of the rotary cylinder 14 is slidably connected to a sliding block 21, wherein the sliding block 21 is fixedly connected at its top to the bottom of the screw rod 22.

[0021] Motor 15 is started, which drives the rotation of rotary cylinder 14, causing the sliding block 21 and the screw rod 22 to rotate. Through the action of the connecting block 2, the screw rod 22 moves up and down during rotation, raising and lowering the movable clamping plate 12 and the connecting plate 13. This adjusts the distance between the movable clamping plate 12 and the mounting clamp 5, allowing the cable to be clamped or released.

[0022] The mounting cover 4 has several groups of bolts 19, and the insert 18 has several groups of through holes that correspond to the bolts 19. The bolts 19 aligning with the through holes allows the mounting block 5 to be quickly disassembled and serviced.

Rotating the end rod 6 moves the mounting sleeve 11, thus enabling quick removal and attachment of the mounting sleeve 11, which facilitates maintenance and battery replacement.

[0026] Preferably, a feed-through hole for cables is provided in each of the upper connecting sleeve 7, the mounting sleeve 20, the mounting cover 4, the insertion piece 18 and the mounting clamp 5. This serves to route power cables and data transmission cables to enable data transmission and maintain the power supply.

[0027] Operating principle: During use, the motor 15 is started, driving the rotary sleeve 14, which then rotates, setting the sliding block 21 and the screw rod 22 into rotation. Through the action of the connecting block 2, the screw rod 22 moves up and down during rotation, raising and lowering the connecting plate 13 and the movable clamping plate 12. This adjusts the distance between the movable clamping plate 12 and the mounting clamp 5 to clamp the line. During the clamping process, the line exerts pressure on the pressure block 26, which transmits this pressure via the connecting rod 25 to the pressure sensor 23. The pressure sensor 23 transmits the measurement data to the control unit in the connecting cylinder 8. The control unit analyzes the data and stops the motor 15 as soon as the pressure reaches the appropriate value.This allows for precise control of the pressure between the grounding terminal and the cable, preventing damage to the cable and equipment from excessive pressure as well as a poor connection due to insufficient pressure. This ensures the stable operation of the power supply system and the safety of the operating personnel. The bolt 19, in conjunction with the through-hole, allows for quick removal and installation of the mounting clamp 5 for maintenance. A rechargeable lithium battery powers the motor 15 and the pressure sensor 23. The rotation of the end rod 6 drives the mounting sleeve 11, which can be quickly removed for battery maintenance or replacement. Furthermore, the through-holes on the relevant components facilitate the routing of power and data cables to ensure proper power and data transmission.
