DETAILED DESCRIPTION

[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0022] like Figure 1-Figure 5As shown, an electrical grounding device for a high-rise building comprises a box body 1 and a junction box 2, wherein a wire placement tube 4 is connected to the top of the box body 1 by threads, wherein the grounding wires of the high-rise residents are placed inside the wire placement tube 4, wherein the grounding wires of the high-rise residents are classified through the wire placement tube 4, so that they can be conveniently managed while being placed, and two groups of docking brackets 101 are installed on both sides of the inner wall of the box body 1 by bolts, wherein the grooves at the center of the docking brackets 101 installed on both sides of the inner wall of the box body 1 are connected to the docking strips of the junction box 2, so that the junction box 2 is engaged with the grooves of the docking brackets 101 through the docking strips, thereby completing the fixation of the junction box 2, and the junction box 2 is arranged at the center of the two groups of docking brackets 101, and the wiring A grounding switch 3 is placed below the box 2. After the grounding wire of the high-rise resident is connected inside the junction box 2, the end of the grounding wire is connected to the grounding switch 3, and the grounding switch 3 introduces the current received by the grounding wire to the ground. A base 7 is provided at the bottom of the grounding switch 3. When the current of the grounding wire is transmitted into the grounding switch 3, the grounding switch 3 connects the current to the base 7, so that the current is transmitted along the connecting bracket 12 inside the base 7 to the grounding electrode 13, so that the grounding electrode 13 transmits the current to the ground. A connecting bracket 12 is installed below the base 7, and a grounding electrode 13 is installed below the connecting bracket 12 by bolts, and the overall structure of the grounding electrode 13 is a triangle, which is a common grounding electrode. The shape of the grounding electrode 13 is high in stability. When the ground is electrically conductive to the ground, the contact area between the grounding electrode 13 and the ground is increased, so that the grounding electrode 13 has a rapid discharge effect. A grounding bracket 22 is installed on the top of the base 7 by bolts. The grounding bracket 22 includes a first bracket 8 and a second bracket 9. The second bracket 9 is installed on the top of the first bracket 8 by bolts. The grounding bracket 22 is the basic structure of the grounding switch 3. It supports all other components and is connected through the first bracket 8 and the second bracket 9 to complete the fixation of the overall structure of the grounding fast switch. A static contact 10 is placed at the center of the first bracket 8 and the second bracket 9. The static contact 10 is an important component of the grounding switch 3. It is used to receive current and The current is transmitted to the base 7, and a connecting plate is installed above the static contact 10, and the connecting plate is above the static contact 10. When the current is transmitted to the joint of the connecting plate, it is transmitted from the connecting plate to the static contact 10, and a bolt clamping structure is used between the grounding switch 3 and the box body 1. A heat dissipation window is arranged on the right side of the box body 1, and a baffle is installed above the heat dissipation window by bolts, and an air outlet 6 is arranged below the heat dissipation window, and a ventilation cavity is arranged at the center of the heat dissipation window and the air outlet 6, wherein a ventilation cavity is reserved inside the box body 1. When air enters the ventilation cavity through the heat dissipation window, the air circulates through the ventilation cavity, and then the air is discharged through the ventilation cavity box air outlet 6, thereby cooling the inside of the box body 1. At the same time, the ventilation cavity is different from the inside of the box body 1.Therefore, even if water drops enter the heat dissipation window, the water drops will not enter the interior of the box 1, and the baffle is also used to reduce the entry of large impurities.

[0023] The junction box 2 includes a placement shell 15 and a sealing plate 17, and the placement shell 15 and the sealing plate 17 of the junction box 2 are the basic structure of the junction box 2, and the wiring wires are used to be placed inside the placement shell 15, and the sealing plate 17 is installed at the opening of the placement shell 15 by bolts, and a wiring bracket 14 is installed on the top of the sealing plate 17, wherein the grounding wire enters the interior of the junction box 2 through the placement hole 1401 of the wiring bracket 14, and the placement hole 1401 is set at the center of the wiring bracket 14.

[0024] Two sets of connection clamps 18 are arranged on the side of the sealing plate 17 away from the housing 15, wherein the connection clamps are used to connect the ground wires, and a grounding protector 19 is placed at the center of the two sets of connection clamps 18. The model of the grounding protector 19 is: GSD-400. The function of the grounding protector 19 is to quickly cut off the power supply when the insulation damage or other faults occur in the electrical system to prevent the current from flowing through the human body or other unexpected paths, thereby ensuring the safety of people and equipment. The grounding protector 19 is usually installed at the entrance or branch line of the distribution system. When it is detected that the leakage current exceeds the set value, it will automatically disconnect the circuit. A fault indicator 20 is placed above the grounding protector 19. The model of the fault indicator 20 is: WD71-XGQ, which is mainly used to monitor the current and voltage in the power system and display or alarm accordingly when a fault occurs. A potential balance box 21 is arranged on the side of the grounding protector 19 away from the docking bracket 101. The potential balance box 21 is used to maintain electrical equipment. By adjusting the characteristic current, the potential fluctuation caused by the external environment or the internal circuit change is offset, and two sets of docking bars are arranged on both sides of the junction box 2, and the two sets of docking bars are of the same size.

[0025] In summary, the utility model uses the box body 1 and the junction box 2. When the grounding wires of the high-rise residents are all placed in the box body 1 through the wire placement tube 4 above the box body 1, the grounding wires are classified through the wire placement tube 4 for easy viewing. The grounding wires pass through the wire placement tube 4 and enter the junction box 2 through the wiring bracket 14. They are placed and classified in the junction box 2. After the placement is completed, after a sufficient length of the grounding wire is reserved, the grounding wire is fixed by the connection wire clamp 18 above the sealing plate 17, and the end of the reserved grounding wire is installed. At the grounding switch 3, when problems such as lightning strike, leakage and electromagnetic interference occur, the grounding wire receives the current, and the current continuously flows through the grounding wire. When the grounding wire flows into the junction box 2, the grounding protector 19 and the potential balance box 21 protect the equipment inside the box 1. The end of the grounding wire is connected to the grounding switch 3, and the current inside the grounding wire is introduced into the grounding switch 3, so that the grounding switch 3 introduces the current into the bottom plate, and the connecting bracket 12 installed inside the bottom plate introduces the current into the grounding electrode 13, so that the grounding electrode 13 introduces the current into the ground, thereby completing the release of the current.
