Description

Technical Field

[0001] This utility model relates to the field of grounding device technology, and specifically to a power construction grounding device. Background Technology

[0002] Grounding devices, also known as grounding electrodes, are metal conductors or groups of conductors that are in direct contact with the soil. They are divided into natural grounding bodies and artificial grounding bodies. Natural grounding bodies include metal pipes, metal well pipes, and metal structures of buildings connected to the earth that are buried underground. Artificial grounding bodies are conductors specifically designed for grounding, such as steel pipes, angle steel, and flat steel.

[0003] In existing methods, conductors are usually driven directly into the ground using tools. After the conductor is driven in, a grounding resistance reducing agent is added to reduce the grounding resistance. However, in practice, due to the deep driving depth of the conductor, the grounding resistance reducing agent cannot fully fill the deep soil gaps around the conductor, resulting in the grounding resistance reducing agent being unable to effectively reduce the grounding resistance around the conductor and affecting the overall performance of the grounding device. Therefore, a power construction grounding device is proposed. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the grounding resistance around the conductor cannot be effectively reduced by the grounding agent, thus affecting the overall performance of the grounding device. This invention provides a power construction grounding device.

The connecting cover is disposed on the top of the fixed rod, and the connecting rod and the guide rod are both disposed inside the fixed rod, and the connecting cover, the connecting rod, and the guide rod are connected in sequence.

[0009] Furthermore, a connecting block is provided on the outside of the fixing rod, the connecting block is located at the bottom end of the fixing rod, and the guide rod slides inside the connecting block.

[0028] like Figures 1 to 6As shown, a power construction grounding device includes: a fixed rod 1, of which there are multiple fixed rods 1, and the fixed rod 1 is hollow. One end of the fixed rod 1 is provided with a connecting pipe 103, and the other end of the fixed rod 1 is provided with an installation groove 104, and the connecting pipe 103 is connected to the installation groove 104; a sliding member 2, disposed inside the fixed rod 1, for guiding the fixed rod 1, the sliding member 2 includes a connecting cover 201, a connecting rod 202, and a guide rod 203. The connecting cover 201 is disposed on the top of the fixed rod 1, and the connecting rod 202 and the guide rod 203 are both disposed inside the fixed rod 1, and the connecting cover 201, the connecting rod 202, and the guide rod 203 are connected in sequence. Specifically, when grounding work is required, first, based on the geological conditions and grounding depth requirements of the construction site, select an appropriate number of fixed rods 1 for assembly. During assembly, insert the connecting pipe 103 of the previous fixed rod 1 into the mounting groove 104 of the next fixed rod 1. If a connecting groove connection is used, ensure that the connecting groove is fully fitted to prevent loosening. If a threaded connection is used, rotate it to a tight state to ensure the stability of the overall structure of the fixed rod 1. Subsequently, install the sliding part 2 inside the fixed rod 1, connecting it in the order of connecting cover 201, connecting rod 202, and guide rod 203. The connection method can also be selected as... The connection can be either grooved or threaded. After connection, check that all components are secure to prevent them from falling off during subsequent operations. After installation, use specialized tools, such as a pile driver or hammer, to vertically drive the fixing rod 1 into the ground. The guide rod 203, with its sharp tip, can break through surface obstacles first, providing guidance for the insertion of the entire fixing rod 1. After the fixing rod 1 is inserted into the ground, its outer connecting plate connects to the ground wire, thus forming a current guiding channel to safely conduct fault current or static electricity in the power system to the ground. The connecting cover 201 can directly withstand the impact force of the tool during the driving process, preventing the top of the fixing rod 1 from deforming due to excessive force. Damage is effectively prevented. The number of connecting rods 202 can be flexibly adjusted according to the required grounding depth. Increasing the number of connecting rods 202 can extend the overall length of sliding part 2, thereby increasing the nailing depth of guide rod 203, ensuring that the fixing rod 1 can penetrate into the soil with better conductivity, and improving the current guiding effect. The shape of connecting rod 202 and guide rod 203 can be selected according to actual construction needs. Cylindrical shape is convenient for sliding inside the fixing rod 1, square column shape can increase the friction with the inner wall of the fixing rod 1 and prevent rotation during sliding, and hexagonal prism shape is convenient for rotation operation with the help of tools, adapting to different installation scenarios.

[0029] like Figures 1 to 6As shown, a connecting block 106 is also provided on the outer side of the fixing rod 1. The connecting block 106 is located at the bottom end of the fixing rod 1, and the guide rod 203 slides inside the connecting block 106. Specifically, during the process of the fixing rod 1 being driven into the ground, the guide rod 203 will slide along the channel inside the connecting block 106. The inner side of the connecting block 106 and the outer side of the guide rod 203 are tightly fitted, which can effectively seal the annular gap between the guide rod 203 and the fixing rod 1, preventing soil, sand and other debris from entering the interior of the fixing rod 1. If debris enters the gap, it will increase the friction when the guide rod 203 slides, and will also cause the fixing rod to become stuck. When rod 1 is driven in, it encounters additional resistance, affecting driving efficiency and verticality. Connecting block 106 significantly reduces the resistance during the driving process of fixing rod 1 by blocking dirt and other debris, making construction more labor-saving and convenient. The connection method between connecting block 106 and fixing rod 1 can be selected according to the convenience of construction. When using the connecting groove connection, simply align the connecting block 106 with the connecting groove at the bottom of fixing rod 1 and insert it to complete the installation. When using the threaded connection, simply rotate the connecting block 106 to a tight state. Both connection methods facilitate operators to quickly install and remove connecting block 106 on site, improving construction efficiency.

[0030] like Figures 1 to 6 As shown, the connecting pipe 103 also has a connecting hole 107 inside, and the fixing rod 1 has a first fixing pin 102 inside, and the first fixing pin 102 is connected to the connecting hole 107. Specifically, during the process of assembling multiple fixing rods 1 through the connecting pipe 103 and the mounting groove 104, when the connecting pipe 103 is inserted into the mounting groove 104 to the preset position, the connecting hole 107 on the connecting pipe 103 will correspond to the mounting hole of the first fixing pin 102 inside the fixing rod 1. At this time, the first fixing pin 102 is inserted into the corresponding hole. If a threaded connection is used, the first fixing pin 102 needs to be rotated until it is completely aligned with the connecting hole 107. If a full engagement is used, an interference fit is required. In this case, a tool is needed to hammer the first fixing pin 102 into the hole to secure it firmly. The limiting effect of the first fixing pin 102 can effectively prevent the assembled fixing rod 1 from sliding or separating under stress, such as the impact force when nailing or the vibration of the current after grounding. This ensures the stability of the overall structure of the fixing rod 1 and guarantees the reliability of the grounding device during long-term use. The stable connection between the first fixing pin 102 and the connecting hole 107 can also avoid problems such as increased grounding resistance caused by loose connection of the fixing rod 1, further improving the performance of the grounding device.

[0031] like Figures 1 to 6As shown, the side wall of the fixing rod 1 also has at least one through hole 105, and the through hole 105 penetrates the fixing rod 1. Specifically, after the fixing rod 1 is completely driven into the ground and reaches the preset depth, the connecting cover 201, connecting rod 202 and guide rod 203 are pulled out from the inside of the fixing rod 1 by means of rotation or pulling out, so that a hollow channel is formed inside the fixing rod 1. At this time, liquid drag-reducing agent can be added into the fixing rod 1 through this channel. The liquid drag-reducing agent will flow downward along the inside of the fixing rod 1 under the action of gravity. Since the side wall of the fixing rod 1 has a through hole 105, and the connecting block 106 is connected to the bottom end of the fixing rod 1, With a small gap, the liquid resistance-reducing agent will penetrate into the soil outside the fixing rod 1 through the through hole 105. At the same time, the connecting block 106 can guide some of the resistance-reducing agent to diffuse into the soil around the bottom of the fixing rod 1. The number of through holes 105 can be selected according to the soil permeability. For soil with poor permeability, the number of through holes 105 can be increased so that the resistance-reducing agent can penetrate into the soil around the fixing rod 1 more evenly and fully, thereby effectively reducing the soil resistivity and improving the conductivity of the grounding device. In addition, the distribution position of the through holes 105 can be set to be staggered vertically to ensure that soil at different depths can contact the resistance-reducing agent.

[0032] like Figures 1 to 6 As shown, the connecting rod 202 also has a second fixing pin 204 inside, and the second fixing pin 204 is connected to the guide rod 203. Specifically, during the connection process between the connecting rod 202 and the guide rod 203, the second fixing pin 204 is inserted into a preset hole inside the connecting rod 202 and makes it cooperate with the corresponding connection structure on the guide rod 203. If the second fixing pin 204 and the connecting rod 202 are connected by a thread, the second fixing pin 204 needs to be rotated until it is in tight contact with the guide rod 203. If an interference fit is used, the second fixing pin 204 needs to be pressed in with a tool. The connecting rod 202 and the guide rod 203 are firmly connected. This connection method can effectively prevent relative displacement or separation between the connecting rod 202 and the guide rod 203 during the nailing process of the fixing rod 1, ensuring the overall stability of the sliding part 2. At the same time, the second fixing pin 204 can also transmit the impact force applied by the tool, enabling the guide rod 203 to break through the ground obstacles more effectively and improve construction efficiency. In addition, the stable connection of the second fixing pin 204 can also ensure that the connecting rod 202 and the guide rod 203 will not fall off accidentally when the sliding part 2 is pulled out, which facilitates the smooth progress of construction operations.

[0033] like Figures 1 to 6As shown, at least one fixing plate 101 is also provided on the outside of the fixing rod 1. Specifically, the connection between the fixing plate 101 and the fixing rod 1 must ensure sufficient strength. If welding is used, it must be ensured that the welding point is firm and without false welding, so that the fixing plate 101 and the fixing rod 1 form a whole. If bolt connection is used, high-strength bolts must be selected and tightened to the specified torque to prevent loosening during use. After the fixing rod 1 is nailed into the ground, the fixing plate 101 will be buried in the soil. Its contact area with the soil is large, which can significantly increase the contact area between the fixing rod 1 and the soil. According to the calculation formula of grounding resistance, the larger the contact area, the smaller the grounding resistance. Therefore, the fixing plate 101 can effectively reduce the grounding resistance of the grounding device and improve the current dissipation effect. At the same time, the fixing plate 101 can also increase the stability of the fixing rod 1 in the soil and prevent the fixing rod 1 from tilting or displacing due to external forces, further ensuring the reliability of the grounding device. The number of fixing plates 101 can be set according to the length and diameter of the fixing rod 1. Generally, multiple fixing plates 101 can be set for each fixing rod 1 and evenly distributed on the outside of the fixing rod 1.

[0034] like Figures 1 to 6 As shown, the working state of this power construction grounding device is as follows: When grounding is required, the fixing rod 1 is first assembled. After the fixing rod 1 is assembled, the connecting cover 201, connecting rod 202 and guide rod 203 are installed inside the fixing rod 1 in sequence. After completion, the fixing rod 1 is nailed into the soil using a tool. After the fixing rod 1 is nailed in, the connecting rod 202 and guide rod 203 are first pulled out from inside the fixing rod 1. Then, liquid resistance reducing agent is added to the inside of the fixing rod 1, so that the liquid resistance reducing agent penetrates to the outside of the fixing rod 1, thereby improving the conductivity of the fixing rod 1 during use.

[0035] In summary, this utility model includes: a fixing rod 1, of which there are multiple fixing rods 1, and the fixing rod 1 is hollow. One end of the fixing rod 1 is provided with a connecting pipe 103, and the other end of the fixing rod 1 is provided with an installation groove 104, and the connecting pipe 103 is connected to the installation groove 104; a sliding member 2, which is disposed inside the fixing rod 1 and is used to guide the fixing rod 1. The sliding member 2 includes a connecting cover 201, a connecting rod 202, and a guide rod 203. The connecting cover 201 is disposed on the top of the fixing rod 1, and the connecting rod 202 and the guide rod 203 are both disposed inside the fixing rod 1, and the connecting cover 201, the connecting rod 202, and the guide rod 203 are connected in sequence. This utility model, through the setting of the fixing rod 1 and the sliding member 2, realizes the guidance of the liquid drag-reducing agent through the cooperation of the fixing rod 1, the connecting pipe 103, the installation groove 104, the connecting cover 201, the connecting rod 202, and the guide rod 203, ensuring that the liquid drag-reducing agent can fully penetrate into the soil outside the fixing rod 1, and ensuring the conductivity of the fixing rod 1 during use.
