Description

Technical Field

[0001] This invention relates to the technical field of electrical installation. More specifically, this invention relates to a grounding stake for electrical installation that prevents it from falling off. Background Technology

[0002] When temporary power is needed at a construction site, to ensure electrical safety, grounding stakes are usually manually inserted into the ground and connected to the electrical equipment via wires to form effective grounding protection. After construction, the grounding stakes can be removed and reused. However, during the process of driving the grounding stakes into the soil with a hammer, if the stake tip hits hard obstacles such as underground rocks, it is very easy for it to deform, curl, or become blunt. This not only increases the difficulty of driving the stakes in for subsequent uses but may also affect the contact between the stake and the soil, thereby reducing grounding performance and shortening the overall service life.

[0003] In addition, the stability of the contact resistance between the grounding pile and the soil is crucial to safety. Traditional steel piles are prone to corrosion, which increases the contact resistance and poses a safety hazard. Summary of the Invention

[0004] In order to overcome the shortcomings of existing grounding piles, such as the pile tip being easily deformed and blunted by impact with hard objects, leading to difficulties in repeated driving and a decrease in grounding effect, this invention provides a grounding pile for power installation that is resistant to falling off.

[0005] Technical solution: A grounding stake for power installation that prevents detachment includes a first round rod and a second round rod fixed to the first round rod; it also includes a connecting block, copper terminals, an end, and a fixing component; the connecting block is fixed to the second round rod; the fixing component is connected to the connecting block; several copper terminals are connected to the fixing component; the fixing component is used to fix the copper terminals; the end is detachably connected to the second round rod; a conical surface is provided on the end.

[0006] Furthermore, it is particularly preferred that the fixing component includes a screw and a nut; a plurality of screws are passed through the connecting block, and copper terminals are passed through the corresponding screws; a nut is screwed onto each screw; each copper terminal is in contact with the corresponding connecting block, and each copper terminal is in contact with the corresponding nut.

[0007] Furthermore, it is particularly preferred that the assembly also includes an auxiliary component, which includes a round rod three and a nut two; a conical surface two is provided on the end; a conical surface three is provided on the round rod two, and the conical surface three contacts the conical surface two; an elongated hole is provided on the round rod two; a round rod three is slidably connected to the round rod two, and the round rod three is located inside the elongated hole, and the round rod three is screwed to the end; a nut two is screwed onto the round rod three, and the lower side of the nut two contacts the round rod one.

[0008] Furthermore, it is particularly preferred that it also includes a U-shaped rod; the U-shaped rod is fixed to the round rod one, and the U-shaped rod is located above the nut two.

[0009] Furthermore, it is particularly preferred that the rod also includes a second screw; the second screw is fixedly connected to the U-shaped rod, and the second screw is aligned with the third round rod.

[0010] Furthermore, it is particularly preferred that the two ends of the screw have chamfers.

[0011] Furthermore, it is particularly preferred that the rod also includes a reinforcing bar; the reinforcing bar is fixed to the inner side of the three round rods.

[0012] Furthermore, it is particularly preferred that the surfaces of the round rod and its ends are coated with a zinc-aluminum alloy; and the copper terminals are made of high-purity annealed copper.

[0013] Furthermore, it is particularly preferred that the round rod three is made of an insulating material.

[0014] Furthermore, it is particularly preferred that the three ends of the round rod have chamfers.

[0015] Beneficial effects: First, by designing the end to be detachable, it can be replaced when the end is deformed, curled, or blunted, so that the grounding stake can be smoothly inserted into the soil to achieve the grounding function when reused. In addition, the copper terminal makes the end of the grounding wire more stable, thereby achieving the effect of preventing it from falling off and improving the grounding stability.

[0016] Second, by setting the upper part of the end to a conical surface two and the lower part of the round rod two to a conical surface three that fits into the conical surface two, when the grounding stake is driven into the ground, the huge impact force makes the conical surface three of the round rod two fit tightly with the conical surface two of the end, thus avoiding the grounding effect being affected by the loose fit between the round rod two and the end.

[0017] Third, the grounding stake can be driven into the ground by simply hitting the U-shaped rod with a hammer. There is no need to deliberately control the hammer to avoid the round rod. This improves the ease of operation and also eliminates the problem of accidentally hitting the round rod.

[0018] 4. During the process of changing the end, when the second nut is unscrewed from the third round rod, the second nut will naturally screw into the second screw rod, and the second screw rod will temporarily fix the second nut, thereby achieving the function of preventing loss.

[0019] Fifth, a rigid reinforcing rod is added inside the round rod three, which is made of insulating material. This improves the structural stability of the round rod three, thereby helping to prevent the round rod two from deforming under stress and ensuring the grounding protection effect and service life.

Detailed Implementation

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0028] Example 1: A grounding stake for power installation that prevents detachment, such as... Figures 1-5 As shown, it includes a circular rod 1 and a circular rod 2; the circular rod 2 is welded onto the circular rod 1; it also includes a connecting block 3, copper terminals 4, an end 5, and a fixing assembly; the connecting block 3 is welded onto the circular rod 2; the fixing assembly is connected to the connecting block 3; two copper terminals 4 are connected to the fixing assembly; the lower end of the circular rod 2 is detachably connected to the end 5; the end 5 is provided with a conical surface 91.

[0029] The fixing assembly includes a screw 6 and a nut 7; two screws 6 are inserted through the connecting block 3, and copper terminals 4 are inserted through the corresponding screws 6; a nut 7 is screwed onto each screw 6; each copper terminal 4 is in contact with the corresponding connecting block 3, and each copper terminal 4 is in contact with the corresponding nut 7. The copper terminals 4 are locked onto the connecting block 3 by the cooperation of the screws 6 and the nuts 7.

[0030] When temporary power is needed, the grounding stake is placed upright on the ground. Then, a hammer is used to strike the round rod 1 downwards, causing it to move the round rod 2 downwards. The round rod 2 then moves the end 5 downwards, allowing the round rod 2 and end 5 to be inserted into the ground, while the connecting block 3 and its components are above ground level. Then, a wrench is used to unscrew the screw 6 and nut 7, and the copper terminal 4 is removed. The end of the grounding wire is then inserted into the copper terminal 4. The copper terminal 4 is then struck with a hammer to deform it and press the grounding wire end inside. The copper terminal 4 is then re-fixed to the connecting block 3 using the screw 6 and nut 7. At this point, the electrical equipment is connected to the earth via the grounding wire, copper terminal 4, connecting block 3, round rod 2, and end 5, achieving grounding protection. This process is more efficient than directly wrapping the grounding wire around the connecting block 3, as the copper terminal 4 presses the end of the grounding wire into the ground. The tighter and more stable design ensures a better grounding stability by preventing the wire from falling off. Both the copper terminal 4 and the end 5 are replaceable, with multiple spares available. After temporary power supply is completed, manually unscrew the screw 6 and nut 7, remove the deformed copper terminal 4, and then screw the screw 6 and nut 7 back into place. Then pull out the grounding stake. Before the next use, if the tip of end 5 is observed to be deformed, curled, or blunted, remove the deformed end 5 and install a new end 5 at the end of the round rod 2. Then insert it into the ground for grounding. During use, the detachable design of end 5 allows for replacement when it becomes deformed, curled, or blunted, ensuring smooth insertion into the ground for repeated use. Furthermore, the tighter grip of the grounding wire end by the copper terminal 4 further stabilizes the grounding wire, preventing it from falling off and improving grounding stability.

[0031] It also includes auxiliary components, including a round rod 3 8 and a nut 2 9; a conical surface 2 92 is provided on the end 5; a conical surface 3 93 is provided on the round rod 2 92, and the conical surface 3 93 contacts the conical surface 2 92; an elongated hole 94 is provided on the round rod 2 94; a round rod 3 8 is screwed onto the end 5, and the round rod 3 8 is located inside the elongated hole 94, and the round rod 3 8 is slidably connected to the round rod 2 94; a nut 2 9 is screwed onto the round rod 3 8, and the lower side of the nut 2 9 contacts the round rod 1 94.

[0032] With the detachable design of end 5, if the round rod 2 and end 5 are not tightly fitted, the resistance will increase significantly, thus interfering with the grounding protection. Therefore, the upper part of end 5 is set as a conical surface 92, and the lower part of round rod 2 is set as a conical surface 93 that fits into conical surface 92. During installation, end 5 is manually screwed into round rod 8, and then round rod 8 is manually inserted into the elongated hole 94 from conical surface 93, and then out from the upper end of elongated hole 94, with conical surface 92 fitting into conical surface 93. Then, nut 29 is manually screwed into the upper end of round rod 8, thereby fixing end 5 and round rod 8 to round rod 2. Then, the grounding stake is placed upright on the ground, and round rod 1 is struck downward with a hammer, causing round rod 1 to move round rod 2 downward, and round rod 2 to move end 5 downward. The head 5 moves downwards, causing the round rod 2 and end 5 to be inserted into the ground. During this process, the impact force generated by the hammering, combined with the resistance of the ground to end 5, forces the conical surface 3 93 of the round rod 2 to be tightly pressed against the conical surface 2 92 of end 5. After driving in, the nut 2 9 is tightened manually again to keep end 5 and round rod 2 in a tight fit, thus ensuring conductivity. In use, by setting the upper part of end 5 as conical surface 2 92 and the lower part of round rod 2 as conical surface 3 93 that fits into conical surface 2 92, when the grounding stake is driven into the ground, the huge impact force causes the conical surface 3 93 of round rod 2 to be tightly fitted against the conical surface 2 92 of end 5, avoiding the problem of interference with grounding protection caused by the round rod 2 and end 5 not being tightly fitted.

[0033] It also includes a U-shaped rod 10; the U-shaped rod 10 is welded onto the round rod 1, and the U-shaped rod 10 is located above the nut 2 9, so as to protect the round rod 3 8 and the nut 2 9.

[0034] Because the round rod 38 protrudes from above the round rod 1, it needs to be deliberately avoided when striking the round rod 1, which is inconvenient and prone to accidental strikes. Therefore, a U-shaped rod 10 was added. When striking, the grounding stake can be driven into the ground by manually striking the U-shaped rod 10 with a hammer. There is no need to deliberately control the hammer to avoid the round rod 38, which improves the convenience of operation and also eliminates the problem of accidentally striking the round rod 38.

[0035] It also includes a screw 11; the screw 11 is welded onto the U-shaped rod 10, and the screw 11 is aligned with the round rod 8.

[0036] The end of the screw 21 is chamfered to make it easier to screw the nut 29 into the screw 21.

[0037] When replacing end 5, manually turn nut 29 upwards so that the upper part of nut 29 is screwed into screw rod 211. Continue turning nut 29 upwards to move it away from round rod 38. At this point, nut 29 is fixed to screw rod 211 and stops fixing round rod 38. Then, manually pull out round rod 38 and end 5, and unscrew the deformed end 5 from round rod 38. Then screw the new end 5 into round rod 38. Then insert end 5 and round rod 38 back into their original positions. Turn nut 29 downwards so that the lower part of nut 29 is screwed into the upper end of round rod 38. Continue turning nut 29 downwards to move it away from screw rod 211 and tighten nut 29 onto round rod 38 to complete the replacement operation. In use, when unscrewing nut 29 from round rod 38 during the replacement of end 5, nut 29 will naturally screw to the outside of screw rod 211, and screw rod 211 will temporarily fix nut 29, thus achieving the function of preventing loss.

[0038] Example 2, based on Example 1, such as Figure 6 As shown, it also includes a reinforcing rod 12; the reinforcing rod 12 is fixedly connected to the inner side of the round rod 8.

[0039] Both the round rod 2 and the end 5 are coated with a zinc-aluminum alloy, which has excellent conductivity and strong resistance to soil corrosion; the copper terminal 4 is made of high-purity annealed copper.

[0040] The third round rod 8 is made of insulating material to prevent it from affecting the current transmission of the second round rod 2.

[0041] The end of the round rod 38 is chamfered to make it easier to screw the round rod 38 into the end 5.

[0042] After the elongated hole 94 is opened on the inner side of the round rod 2, its side will be squeezed by the soil during the process of inserting the round rod 2 into the soil. At this time, the round rod 3 8, which is in close contact with the round rod 2, is used to support it to prevent the side wall of the round rod 2 from deforming due to the squeeze. At the same time, a reinforcing rod 12 of rigid material (such as metal) is set on the inner side of the round rod 3 8 to improve the structural stability of the round rod 3 8 of insulating material (such as rubber), further preventing the round rod 2 from deforming, so as to ensure the grounding protection effect and service life.
