Description

Technical Field

[0001] The utility model relates to the technical field of electric power construction, in particular to a grounding protection device for electric power construction. Background Art

[0002] In order to improve the safety of power equipment, high-power power equipment (especially outdoor power equipment) must be equipped with corresponding grounding protection devices. Existing grounding protection devices often use similar structures such as tripods to ensure reliable and stable grounding, and set corresponding ground nails and other similar structures at the positions of the three supporting legs. When these ground nails are inserted into the ground, they often need to be plugged in one by one, which increases the complexity of installation. In addition, a single ground nail is more likely to detach from the supporting leg (and also the soil), which will affect the stability of the other supporting legs and the ground (that is, the stability of the overall position), highlighting the shortcomings of the existing technology.

DETAILED DESCRIPTION

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] like Figure 1-Figure 3 As shown, a grounding protection device for power construction includes a main support tube 1, a support foot 2, a secondary support tube 3, a slot 4, a ground nail 5, a main support rod 6, a pushing claw 7, a support plate 8, a ground plug 9, and a fastening assembly 10. Three support feet 2 inclined outward and downward are fixed at equal angles on the circumference of the bottom outer wall of the main support tube 1, and a vertical secondary support tube 3 is fixed to the top of the end of each support foot 2 away from the main support tube 1. A vertical slot 4 runs through the middle of the secondary support tube 3. A vertical ground nail 5 is inserted in the common upper and lower gaps between the secondary support tube 3 and the support foot 2. The main support tube 1 is slidably connected to the vertical main support tube 1. The support rod 6 has three pushing claws 7 fixed at equal angles on the outer circumferential wall at the bottom of the main support rod 6, and each pushing claw 7 is respectively plugged into the supporting foot 2 with an upper and lower gap, and each pushing claw 7 can be respectively plugged into the slot 4 with an upper and lower gap, and the bottom end of the pushing claw 7 can contact the top of the ground nail 5. The bottom end of the main support rod 6 and the bottom end of each pushing claw 7 are jointly fixed with a horizontal support plate 8, and a vertical ground plug 9 is fixed to the bottom end of the support plate 8. The main support rod 6, support plate 8 and ground plug 9 are all made of metal, and a fastening assembly 10 is installed on the upper part of the main support rod 6, and the fastening assembly 10 can be connected to the ground wire.

[0018] The fastening assembly 10 includes a lower hexagonal cylinder 11, an externally threaded cylinder 12, a secondary support rod 13, a limiting ring 14, a threading hole 15, a countersunk threaded hole 16, a wire pressing bolt 17, an upper hexagonal cylinder 18, and a pressing ring 19. The top of the main support cylinder 1 is coaxially fixed with a vertical lower hexagonal cylinder 11, and the top of the lower hexagonal cylinder 11 is coaxially fixed with an externally threaded cylinder 12. The main support rod 6 is slidably connected with the lower hexagonal cylinder 11 and the externally threaded cylinder 12 up and down. The top of the main support rod 6 is fixed with a vertical secondary support rod 13, and a limiting ring 14 is fixed between the secondary support rod 13 and the main support rod 6. A threading hole 15 is provided on the upper part of the secondary support rod 13, and the threading hole 15 simultaneously passes through the top and outer circumference of the secondary support rod 13 The wall, the threading hole 15 is bent at an obtuse angle. After the ground wire is plugged into the bent threading hole 15 and tightened by the wire-pressing bolt 17, it is more difficult to fall off than a straight structure, and compared with a right-angle or acute-angle structure, the damage to the ground wire is smaller. The secondary support rod 13 has two horizontal countersunk threaded holes 16, and the two countersunk threaded holes 16 are respectively threadedly connected with a wire-pressing bolt 17, and the two wire-pressing bolts 17 are respectively plugged into the two threading holes 15. The external threaded tube 12 is coaxially threadedly connected with a vertical upper hexagonal tube 18, and a pressure ring 19 is coaxially fixed to the inner wall of the upper hexagonal tube 18. The pressure ring 19 can be plugged into the secondary support rod 13 with a gap, and the bottom end of the pressure ring 19 can be against the top of the limit ring 14.

[0019] The bottom end of the upper hexagonal tube 18 can abut against the top end of the lower hexagonal tube 11. When the bottom end of the upper hexagonal tube 18 abuts against the top end of the lower hexagonal tube 11, the upper hexagonal tube 18 and the lower hexagonal tube 11 are aligned vertically. When the bottom end of the upper hexagonal tube 18 abuts against the top end of the lower hexagonal tube 11, the limit ring 14 is pressed between the pressure ring 19 and the external threaded tube 12. When the bottom end of the upper hexagonal tube 18 abuts against the top end of the lower hexagonal tube 11, the bottom end of the support plate 8 is flush with the bottom end of the support foot 2. The upper hexagonal tube 18 and the lower hexagonal tube 11 are jointly plugged with a vertical sleeve 20. When the sleeve 20, the upper hexagonal tube 18 and the lower hexagonal tube 11 are jointly plugged, the upper hexagonal tube 18 and the lower hexagonal tube 11 cannot rotate relative to each other, thereby preventing the upper hexagonal tube 18 and the lower hexagonal tube 11 from rotating accidentally, thereby ensuring the stability of the upper and lower positions of the main support rod 6 compared to the main support tube 1, and then ensuring the stability of the relative positions of the support plate 8 and the support foot 2.

[0020] An anti-slip ring 21 is fixed to the upper part of the outer wall of the upper hexagonal cylinder 18, and the bottom end of the anti-slip ring 21 can contact the top end of the sleeve 20. When the top end of the sleeve 20 contacts the bottom end of the anti-slip ring 21, the bottom end of the sleeve 20 is higher than the bottom end of the upper hexagonal cylinder 18. When the upper hexagonal cylinder 18 is threadedly connected with the external threaded cylinder 12, the sleeve 20 can be prevented from being separated from the upper hexagonal cylinder 18, and when the top end of the sleeve 20 contacts the bottom end of the anti-slip ring 21, the upper hexagonal cylinder 18 can be easily rotated.

[0021] A sponge block 22 is fixed to the upper penetration point of the upper hexagonal cylinder 18 , and a cross-shaped threading groove 23 is passed through the middle of the sponge block 22 from top to bottom, so as to facilitate the insertion of the ground wire, and the sponge block 22 can be used to protect the ground wire.

[0022] A reflective strip 24 is pasted on the outer wall of the support foot 2, a hexagonal column-shaped mounting tube 25 is fixed to the outer wall of the main support tube 1, and a plurality of fluorescent panels 26 are fixed to the side wall of the mounting tube 25. The reflective strip 24 and the fluorescent panel 26 work together to not only reflect light but also emit light, thereby improving the warning effect at night.

[0023] The working principle of the utility model is as follows: initially, the upper hexagonal tube 18 is not threadedly connected with the external threaded tube 12. At this time, the pushing claw 7 can move up and down along the supporting foot 2, and the ground nail 5 can also be completely accommodated in the auxiliary supporting tube 3. Then, the device is placed vertically on the ground, and then the main supporting rod 6 is pushed downward. The pushing claw 7 can be used to press the ground nail 5, so that the ground nail 5 slides downward along the auxiliary supporting tube 3, and the ground plug 9 can be moved downward at the same time, so that the ground nail 5 and the ground plug 9 are both inserted into the ground. When the bottom end of the support plate 8 is in contact with the ground, the ground nail 5 and the ground plug 9 have also reached the maximum insertion limit. At this time, the upper hexagonal tube 18 can be used to be threadedly connected with the external threaded tube 12. , and make the bottom end of the upper hexagonal tube 18 contact with the top end of the lower hexagonal tube 11, so that the limit ring 14 can be clamped by the pressure ring 19 and the external threaded tube 12, and the upper hexagonal tube 18 and the lower hexagonal tube 11 can be aligned, and then the sleeve 20 is pushed downward, so that the sleeve 20 can be plugged into the upper hexagonal tube 18 and the lower hexagonal tube 11 at the same time, thereby preventing the upper hexagonal tube 18 and the lower hexagonal tube 11 from rotating relative to each other. At this time, the three pushing claws 7 are simultaneously against the top of the ground nail 5, so as to prevent a single ground nail 5 from being separated from the soil, thereby improving the stability of the device, and then the ground wire is passed through the threading groove 23 and then inserted into the threading hole 15, and then the wire pressing bolt 17 is used to tighten it to achieve grounding.

[0024] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
