Description

Technical Field

[0001] This invention relates to the field of maintenance tool technology, and more specifically to a complete set of grounding wire grounding terminals with automatic alarm function. Background Technology

[0002] Power plants are mostly equipped with a large number of transformers, especially large power plants, which are equipped with plant service transformers, excitation transformers, electric braking transformers, unit self-use transformers, generator neutral point transformers, etc. During the maintenance of unit equipment, there are many grounding wires that need to be connected.

[0003] Equipment maintenance grounding wires generally include a conductor end, a grounding wire, and a grounding end. Currently, there are two problems with the grounding end of the grounding wire. First, when installing the grounding wire, the grounding end is pressed onto the grounding copper plate stud with a nut. During the installation and removal process, tools such as wrenches are needed to tighten the nut onto the grounding end, which is time-consuming and laborious. Second, the grounding stud protrudes from the ground or wall, which may cause accidental injury to personnel or loosening of the nut. Summary of the Invention

[0004] The purpose of this invention is to provide a complete set of grounding wires with automatic alarm function, in order to solve the technical problems in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A complete set of grounding wire grounding terminals with automatic alarm function includes:

[0007] The grounding terminal has a guide groove that communicates with the upper surface.

[0008] A grounding contact block is slidably disposed in the guide groove, and the grounding contact block is connected to the inner wall of the guide groove;

[0009] An elastic limiting unit is disposed on the grounding terminals on both sides of the guide groove;

[0010] The grounding end of the grounding wire is set in the guide groove and fixed by the elastic limiting unit, so that the grounding end of the grounding wire contacts the grounding end contact block.

[0011] An elastic support unit is disposed in the guide groove below the grounding end contact block;

[0012] An alarm resilient switch is located at the bottom of the guide groove and is used to activate the alarm when the grounding contact block is pressed. Here, alarm activation means the alarm is short-circuited; that is, the alarm does not sound when the resilient switch is pressed, and only activates when the resilient switch is released and reset.

[0013] In some embodiments, the elastic limiting unit includes a snap-fit ​​slider, a snap-fit ​​button, and a snap-fit ​​spring. Slots communicating with the guide groove are respectively formed on the grounding terminals on both sides of the guide groove. Two snap-fit ​​sliders are respectively disposed within the slots, and the slots limit the vertical displacement of the snap-fit ​​sliders. The two ends of the snap-fit ​​spring are respectively connected to the ends of the snap-fit ​​slider and the slots. A through guide slot is formed on the upper surface of the grounding terminal. The snap-fit ​​button is disposed on the snap-fit ​​slider and extends from the guide slot.

[0014] In some embodiments, the elastic support unit is a support spring, the top of which is connected to the bottom of the grounding contact block, and the bottom of which is connected to the bottom of the guide groove.

[0015] In some embodiments, the alarm resilient switch is disposed at the bottom of the guide groove corresponding to the middle of the support spring.

[0016] In some embodiments, an alarm is also included, which is connected to an alarm resilient switch via a connecting wire. A grounding alarm contact wiring hole is provided at the bottom of the guide groove, and the connecting wire passes through the grounding alarm contact wiring hole.

[0017] In some embodiments, the two ends of the grounding terminal are provided with mounting steps, and the mounting steps are provided with through holes for grounding point fixing bolts.

[0018] The beneficial effects of this invention compared to the prior art are:

[0019] This patent addresses the problems existing in current grounding wire grounding terminals by optimizing the existing grounding terminals and clamping ends to achieve rapid installation and removal of the grounding terminals. This patent uses a snap-fit ​​device to press or pull the grounding terminal in with a certain force, enabling quick installation and removal. This saves operation time during equipment maintenance, improves work efficiency, and ensures equipment and personnel safety. It also features a grounding wire detachment alarm function and can be connected to audible and visual alarm devices and IoT platforms. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0027] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0028] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or display that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or display.

[0029] The following will combine Figures 1-2 This application provides a detailed description of a complete set of grounding wires with automatic alarm function, as illustrated in the embodiments of this application. It is worth noting that the following embodiments are merely illustrative of this application and do not constitute a limitation thereof.

[0030] Example 1:

[0031] like Figure 1-2 As shown, a complete set of grounding wire grounding terminals 1 with automatic alarm function includes: a grounding terminal connector, a grounding contact block 2, an elastic limiting unit, a grounding wire grounding terminal 1, an elastic support unit, and an alarm elastic switch 7. The grounding terminal connector has a guide groove communicating with its upper surface; the guide groove can be cylindrical or rectangular. The grounding contact block 2 is slidably disposed within the guide groove, and the outer contour of the grounding contact block 2 is adapted to the guide groove. This ensures that the grounding contact block 2 can only move vertically up and down within the guide groove. Furthermore, the grounding contact block 2 is connected to the inner wall of the guide groove.

[0032] The grounding terminal has mounting steps at both ends, and through holes 8 for grounding point fixing bolts are provided on the mounting steps. The grounding terminal 1 of the grounding wire is crimped and fixed to the grounding wire, and the grounding point is fixed by bolts and grounding copper busbars through the through holes 8 for grounding point fixing bolts.

[0033] The elastic limiting unit is disposed on the grounding terminals on both sides of the guide groove; the elastic limiting unit includes a snap-on slider 4, a snap-on button 3, and a snap-on spring 5. A sliding groove communicating with the guide groove is provided on the grounding terminals on both sides of the guide groove. The two snap-on sliders 4 are respectively disposed in the sliding groove, and the displacement of the snap-on sliders 4 in the vertical direction is limited by the sliding groove. The two ends of the snap-on spring 5 are respectively connected to the snap-on slider 4 and the end of the sliding groove. A through guide groove 11 is provided on the upper surface of the sliding groove and the grounding terminal. The snap-on button 3 is disposed on the snap-on slider 4 and extends out from the guide groove 11.

[0034] The grounding terminal 1 of the grounding wire is disposed within the guide groove and is fixed by an elastic limiting unit, ensuring contact between the grounding terminal 1 and the grounding contact block 2. An elastic support unit is disposed within the guide groove below the grounding contact block 2. The elastic support unit is a support spring 6, with its top connected to the bottom of the grounding contact block 2 and its bottom connected to the bottom of the guide groove. An alarm elastic switch 7 is disposed at the bottom of the guide groove and is used to activate the alarm 10 when the grounding contact block 2 is pressed. It can emit an audible and visual alarm and simultaneously transmit alarm information to a monitoring system or other terminals via network. This allows for rapid removal of the grounding wire, reducing labor costs.

[0035] Without applying external force to the latch button 3, the latch slider 4 extends partially into the guide groove under the elastic action of the latch spring 5; the grounding terminal 1 of the grounding wire does not contact the alarm elastic switch 7 under the action of the support spring 6, thus not triggering the alarm 10 to work.

[0036] When it is necessary to connect the grounding terminal 1 of the grounding wire to the grounding terminal, the two latching sliders 4 are retracted using the latching button 3, meaning the latching sliders 4 can be fully retracted into the groove. Then, the grounding terminal 1 of the grounding wire is placed in the guide groove, so that the grounding contact block 2 is pressed down. The grounding terminal 1 of the grounding wire contacts the grounding contact block 2, thus achieving conductivity with the grounding terminal. Then, the applied force on the latching button 3 is released, and the latching button 3 resets under the action of the latching spring 5, limiting the grounding terminal 1 of the grounding wire. At this time, the downwardly moving grounding contact block 2 compresses the support spring 6 and triggers the alarm elastic switch 7, realizing the conduction of the alarm 10. Here, the conduction of the alarm 10 means that the alarm 10 is short-circuited, that is, the alarm 10 does not sound when the alarm elastic switch 7 is pressed. The alarm 10 only starts to work and sound when the alarm elastic switch 7 is released and reset.

[0037] If the grounding terminal 1 of the grounding wire is disconnected from the grounding terminal connector, that is, if the grounding terminal 1 of the grounding wire is detached from the grounding contact block 2, the grounding contact block 2 will reset under the action of the support spring 6, releasing the pressure on the alarm's elastic switch 7, and the alarm 10 will start working and sounding. It should be noted that the grounding contact block 2 will not touch the latch slider 4 extending into the guide groove when it resets under the action of the support spring 6.

[0038] In some embodiments, the alarm resilient switch 7 is disposed at the bottom of the guide groove corresponding to the middle of the support spring 6. An alarm 10 is also included, which is connected to the alarm resilient switch 7 via a connecting wire. A grounding alarm contact wiring hole 9 is provided at the bottom of the guide groove, and the connecting wire passes through the grounding alarm contact wiring hole 9.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
