The link of described hammer nail is designed with the connection screw that adapts to connecting bolt.This screws on or pulls down hammer through connecting bolt during just for installation exercise and follows closely that provide in upper rod, a rod, lower stick end may.
Described electrical connection sheet lower, neck end, upper rod, a rod, lower excellent two ends neck, ground nail upper end neck all are designed with and are matched with the access slot of pulling that uses spanner rotation usefulness.This utilize during just for installation exercise spanner screw in opposite directions to connect they provide may.
The installation process of the modular electrical earth rod that the employing percussion tool that the utility model implements to obtain is buried underground is as follows:
Install and prepare:
1, ground nail is spun upper connecting bolt, partly put the annular resilient packing ring at the connecting bolt that exposes, be connected in lower excellent lower end through the connecting bolt exposed portions serve again, that uses that spanner aims at lower excellent lower, neck end, ground nail upper end neck pulls rod, ground nail under the access slot opposite direction rotating, press seal circle;
2, the upper end of lower rod is through the connecting bolt upper hammer nail that spins;
3, the upper end of rod, upper rod is connected with connecting bolt in advance between will be to be buried underground.
Bury underground:
1, selects the suitable place of burying underground, operator's hand-held impact instrument, such as electric pick, the hammer nail of rod upper end under the clamping, start electric pick because lower excellent lower end has been connected with the ground nail that the top becomes inverted cone-shaped, utilize electric pick to make its downward impulsive force, lower rod is squeezed into soil layer slowly, until lower rod only bassets approximately 20 centimetres;
2, will hammer nail into shape screws off from connecting bolt, then put sealing ring in the connecting bolt exposed portions serve, the screw of excellent lower end between the connecting bolt exposed portions serve is aimed at is with the access slot of pulling of excellent lower, neck end, lower rod upper end neck between the spanner aligning, rod, lower rod between opposite direction rotating are with the sealing ring compacting.
3, will hammer into shape nail be rotatably connected in the upper end be connected with in advance connecting bolt between rod upper end, operator's hand-held impact instrument, such as electric pick, the hammer nail of rod upper end between clamping is rotatably connected in, start electric pick, utilize its downward impulsive force will between rod-lower rod-ground nail slowly squeeze into soil layer, until a rod only bassets approximately 20 centimetres;
4, will hammer nail into shape screws off from connecting bolt, then put sealing ring in the connecting bolt exposed portions serve, the connecting bolt exposed portions serve is aimed at the screw of upper excellent lower end, aim at the access slot of pulling of upper excellent lower, neck end, a rod upper end neck with spanner, rod, upper rod between opposite direction rotating are with the sealing ring compacting.
5, will hammer nail into shape is tightened on the connecting bolt that spins in advance on the rod, operator's hand-held impact instrument, such as electric pick, the hammer nail of rod upper end between clamping is rotatably connected in, start electric pick, utilize its downward impulsive force that a upper rod-rod-lower rod-ground nail is squeezed into soil layer slowly, until the length that upper rod bassets meets the requirement of electrical grounding standard;
6, will hammer nail into shape and screw off from connecting bolt, and then put sealing ring in the connecting bolt exposed portions serve, and the connecting bolt exposed portions serve be aimed at the screw of electrical connection sheet lower end, upper electric brace spins; Aim at the access slot of pulling of electrical connection sheet lower, neck end, upper rod upper end neck with spanner, opposite direction rotating electrical connection sheet, upper rod are with the sealing ring compacting.
7, use the electrical grounding detecting instrument, the electric parameter that electric parameter is recorded on the electrical connection sheet label hanging wire hole records on the label, and the whole process of burying underground is finished.
The modular electrical earth rod that the employing percussion tool that the utility model implements to obtain is buried underground through on probation, is compared with existing electrical grounding rod, has shown following beneficial effect:
1, installation is buried underground simple and easy.As previously mentioned, existing electrical grounding rod when burying operation underground, can only rely on manpower to excavate soil layer to the long corresponding degree of depth of rod the time, place earth rod backfill earth again again after the prescribed depth, the compacting soil layer just can be finished; Bury underground after excavation machinery is excavated even enable, but operating type is also substantially identical.For grounding requirement quite high electrical grounding or thunder-lightning system earth, then because earth rod reaches more than 2 meters, bury underground just more require great effort time-consuming, difficult.And electrical grounding rod of the present utility model only needs operator 1 people to carry out when burying operation underground, need not require great effort and time-consumingly cut the earth, bankets.Not only operating efficiency increases substantially, and because be with electrical grounding bastinade underground layer, compares with the installation quality of cutting the earth when burying operation underground, banketing of existing electrical grounding rod, and the electric parameter of sign installation quality significantly promotes.
2, packed and transported is convenient.As previously mentioned, compare with the whole elongated rod shape electrical grounding rod of prior art, modular electrical earth rod of the present utility model, can take apart easily and be the independent parts such as electrical connection sheet, upper rod, a rod, lower rod, ground nail, connecting bolt, sealing ring, hammer nail, it packs simple specification, and transportation is also just easily convenient.
