Description

Technical Field

[0001] This invention relates to the field of grounding equipment, and in particular to a self-adjusting grounding tool. Background Technology

[0002] Closing a grounding switch while it is energized is an extremely dangerous operation. In actual operation, accidental closing of the grounding switch due to damage to electrical components or accidental contact of operating components occurs frequently. However, in many cases, the problem is due to component defects that cannot be avoided even by proper operating procedures. For damage to electrical components, the problem can be solved by improving the stability of electrical connections and by dividing the power distribution equipment into zones. However, for accidents caused by accidental contact or improper operation of control switches of hardware such as operating components, as well as wear and tear of the components themselves, the existing solutions usually focus on strengthening and protecting the components. For avoiding these situations, the solution is often to use other electrical components or add rigid equipment for prevention, which cannot directly address the potential dangers caused by hardware defects from multiple angles.

[0032] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the present invention will be described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure will be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0035] Furthermore, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0036] Example 1

[0037] Reference Figures 1-6 This embodiment provides a self-adjusting grounding fixture, including a grounding component 100. The grounding component 100 is the relevant component responsible for completing the entire grounding process. It includes a base 101, which is responsible for supporting most of the relevant components. Grounding posts 101a and grounding gates 101b are arranged equidistantly on the base 101. Grounding is completed when the corresponding ends of the gate and the posts come into contact. The stability and safety of the grounding are achieved by the linkage of other components of the present invention. The base 101 is also provided with a liquid storage chamber 101c. The liquid storage chamber 101c is a chamber for storing liquid with an opening and a sliding area, which can form a completely closed space with other components. A pressure supply component 102 is slidably connected to the liquid storage chamber 101c through a slide rail 101d. The pressure supply component 102 is in the liquid storage chamber 101c. By displacement, it squeezes the liquid in the liquid storage chamber 101c to achieve the technical effect.

[0038] Furthermore, the control component 200, which is another transmission component used to ensure the stable and safe operation of the entire grounding process, includes a side plate 201 fixedly connected to the side of the base 101. The side plate 201 has a sliding groove 201a, which can be understood as two channels. A pressure-bearing component 202 is slidably connected in the sliding groove 201a. The pressure-bearing component 202 slides in the channel. Hydraulic oil W flows between the inside of the sliding groove 201a and the inside of the liquid storage chamber 101c. In the default state, all the hydraulic oil W is stagnant in the liquid storage chamber 101c. After the pressure-bearing component 102 moves, it squeezes the hydraulic oil W, which flows towards the inside of the sliding groove 201a, thereby further driving the pressure-bearing component 202 to move.

[0039] Example 2

[0040] Reference Figures 1-5 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, and differs from the previous embodiment in that: a pressure boosting channel 101c-1 is provided at one end of the liquid storage chamber 101c. The pressure boosting channel 101c-1 is composed of multiple small channels. For the large-cavity liquid storage chamber 101c, it is a component that enhances the hydraulic effect. The side of the pressure boosting channel 101c-1 near the control component 200 is connected to the inside of the slide 201a through the liquid flow pipe 101c-2. The liquid flow pipe 101c-2 further pressurizes and releases liquid. The liquid pushed by the high pressure will gradually flow into the inside of the slide 201a and lift the pressure-bearing component 202.

[0041] Furthermore, the pressure-receiving component 202 includes a slider 202a slidably connected within the slide groove 201a. The slider 202a fits against the inner wall of the slide groove 201a. A miniature oil inlet 202a-1 is fixedly provided on the side of the slider 202a that contacts the hydraulic oil W, and an oil injection pipe 202b is provided on the opposite side. The establishment of the miniature oil inlet 202a-1 causes the pressure-receiving component 202 to apply pressure to the surface of the hydraulic oil W in turn, while also causing a small amount of hydraulic oil W to enter the oil inlet 202a-1. The oil injection pipe 202b allows this part of the hydraulic oil W to flow upward. A scattering nozzle 202b-1 is provided at one end of the opening of the oil injection pipe 202b. After being pressurized multiple times, the hydraulic oil W reaches the scattering nozzle 202b-1 and is dispersed and sprayed out to form a liquid mist.

[0042] Furthermore, the pressure-bearing component 202 also includes a receiving sheet metal 202c fixedly connected to the slider 202a. The main function of the receiving sheet metal 202c is to further adhere to the inner wall of the slide groove 201a to ensure stable sliding speed and prevent it from being too fast. The receiving sheet metal 202c is provided with a drain port 202c-1. The drain port 202c-1 allows the sprayed liquid mist to not only affect the receiving sheet metal 202c itself, but also further affect the components in front. An oil drain plate 202d is fixedly connected to the end of the receiving sheet metal 202c away from the scattering nozzle 202b-1. A connecting shaft 202e is fixedly connected to the end of the oil drain plate 202d in the same direction away from the scattering nozzle 202b-1. In this way, the small amount of hydraulic oil W sprayed from the scattering nozzle 202b-1 can completely cover the entire pressure-bearing component 202, which can prevent the components from wearing or experiencing excessive friction.

[0043] Furthermore, the connecting shafts 202e are rotatably connected by connecting rods 203. Since there are two slides 201a, there are multiple connecting rods 203. In addition to connecting the connecting shafts 202e, the connecting rods 203 are also connected to the grounding switch shaft 103 at their ends. The grounding switch 101b is fixedly sleeved on the grounding switch shaft 103 at equal intervals. Under the action of the connecting rods, the connecting shafts 202e move along the slide 201a following the pressure-bearing component 202, which causes the grounding switch 101b to rotate.

[0044] Example 3

[0045] Reference Figures 1-6 This is the third embodiment of the present invention. This embodiment provides a self-adjusting grounding tool. This embodiment is based on the previous embodiment, and the difference from the previous embodiment is that: one end of the grounding gate 101b is provided with a contact port 101b-1, and the other end is provided with a telescopic positioning rod 101b-2. The contact port 101b-1 is the grounding contact point. When it touches the grounding post, grounding will occur. The telescopic positioning rod 101b-2 is used to drive other components to produce an effect, and it is also a telescopic conventional sleeve structure itself.

[0046] In detail, the opening of the contact port 101b-1 can be embedded with the end of the grounding post 101a to form a grounding state;

[0047] In detail, the telescopic positioning rod 101b-2 is provided with an inclined surface M and a ball end S. The inclined surface S ensures that the telescopic positioning rod 101b-2 can produce a telescopic effect when it comes into contact with other parts, avoiding displacement obstacles. The ball end S is also used to reduce friction caused by contact with other parts.

[0048] In detail, the pressure piece 102 has a sloping sliding surface 102a on one side, facing the telescopic positioning rod 101b-2; the base 101 has a tilting sheet metal 104, and the positioning hole 104a on it will allow the telescopic positioning rod 101b-2 to be inserted when the grounding switch 101b is in a non-grounded state, so as to avoid mis-grooving and causing accidental contact with the switch wrench. If you want to operate the switch wrench, you must first push the telescopic positioning rod 101b-2 back from outside the equipment so that it leaves the limit of the positioning hole 104a.

[0049] In detail, the concave part of the inclined surface of the tilting sheet metal 104 faces the position of the telescopic positioning rod 101b-2, thus forming a state in which the inclined surface M can contact and slide relative to the end of the tilting sheet metal 104. When the telescopic positioning rod 101b-2 rotates with the grounding gate 101b, it touches the top of the tilting sheet metal 104, thereby the end is squeezed back. The ball end S can ensure that it rotates normally in the concave part of the tilting sheet metal 104. At the same time, when the inclined sliding surface 102a is in the grounding state, the grounding gate 101b needs to rotate 45° to connect with the grounding post 101a. Therefore, after rotation, the telescopic positioning rod 101b-2 releases the restriction of the tilting sheet metal 104, extends its full length, and pushes the inclined sliding surface 102a, driving the pressure member 102 to move.

[0050] Furthermore, the side plate 201 is provided with a slide rail sealing plate 201b, which is placed on the opening side of the slide groove 201a. The closed space formed by the slider 202a, the slide rail sealing plate 201b, and the slide groove 201a can be filled with hydraulic oil W. At this time, the slide rail sealing plate 201b can ensure that no matter how the pressure-bearing component 202 moves, there will be no oil leakage.

[0051] Example 4

[0052] Reference Figures 1-6 This is the fourth embodiment of the present invention. This embodiment provides a self-adjusting ground tool fixture. This embodiment is based on the previous embodiment, and the difference from the previous embodiment is that: the base 101 is provided with an isolation plate 101e, which surrounds the side plate 201 to prevent the very small amount of oil droplets that may leak from the oil leakage pan 202d due to excessive negative pressure from affecting other components.

[0053] Furthermore, the base 101 is provided with an oil return port 101f, which is located inside the isolation plate 101e. This part is designed to reuse these sprayed oil droplets, allowing them to flow back to the inclined oil return port 101f under the influence of gravity and return to the liquid storage chamber 101c.

[0054] Furthermore, the slide 201a includes a longitudinal slide 201a-1 and a bent slide 201a-2, and a switch handle is fixedly connected to the connecting shaft 202e within the longitudinal slide 201a-1. The entire workflow can now be summarized as follows:

[0055] During grounding: Push the telescopic positioning rod 101b-2 away from the positioning hole 104a, and simultaneously pull the switch handle. Before the telescopic positioning rod 101b-2 leaves the tilting sheet metal 104, the switch handle is manually turned. Then, under the influence of the rotation of the grounding gate 101b, the liquid in the reservoir 101c is squeezed into the slide groove 201a by the pressure-applying component 102 and the telescopic positioning rod 101b-2. Throughout the process, due to the high hydraulic pressure but slow filling speed, a high-pressure liquid column is generated to provide auxiliary support and protect the part that has just been positioned. This continues until the hydraulic oil W is filled to the top, completing the positioning and protection.

[0056] When the grounding is released: Press the switch handle. Due to gravity, pressing the switch downwards will definitely apply more force. So at this time, the operator is facing the liquid surface pressure and the torque friction generated by rotation. Although the resistance is relatively large, it is negligible. At this time, the pressure block 202 applies a thrust to the hydraulic oil W downwards. As mentioned above, with the assistance of relevant components, the hydraulic oil W can spray oil to lubricate the entire pressure block 202. The amount of oil consumed is very small, which can avoid excessive friction and resistance during use, which could cause damage. The consumed oil can also be reused through the oil return port 101f until the hydraulic oil W is pushed back into the reservoir 101c. With the assistance of other components, stable positioning and limit are completed to avoid accidental activation.

[0057] When the grounding gates 101b and 101b are closed, they form a 45° angle with each other, which is different from the 90° angle of the prior art. This makes the torque friction required to turn the handle less and helps to optimize the equipment layout, reduce the area, and reduce mechanical fatigue. The hydraulic oil W can be made of insulating silicone oil to minimize the impact on electrical equipment.
