Description

Technical Field

[0001] This utility model relates to a grounding device for conventional railways, specifically a railway grounding reinforcement device. Background Technology

[0002] Most signaling equipment grounding systems on conventional railways do not employ integrated grounding designs, but rather traditional independent grounding methods. While this method may meet basic requirements in ordinary sections, it presents significant limitations when encountering long bridge sections or sections with extremely high soil resistivity, such as gravel or rock subgrades. In these special sections, the soil's conductivity is extremely poor, resulting in severely ineffective current dissipation from the grounding device, making it difficult to reduce the grounding resistance of the signaling equipment below the threshold required by safety regulations. To address this common problem, on-site maintenance units typically employ emergency or remedial measures such as adding a single vertical or horizontal grounding electrode to improve grounding performance by increasing the contact area between the grounding electrode and the soil.

[0003] However, the conventional method of using a single grounding electrode is ineffective in practical applications. The fundamental reason is that in environments with already poor grounding conditions, the current dissipation range of a single grounding electrode is limited, easily reaching its current discharge capacity limit. Furthermore, isolated treatment is not only cost-effective but also fails to fundamentally solve the problem, leading to recurring instances of substandard equipment grounding resistance, posing a long-term threat to the stable operation of railway signaling systems and traffic safety.

[0004] Therefore, it is necessary to propose new measures to overcome the above-mentioned shortcomings. Summary of the Invention

[0005] The purpose of this invention is to provide a railway grounding reinforcement device to solve the problem that the current method of reducing grounding resistance by a single grounding electrode is not very effective.

[0012] Furthermore, the fixing assembly includes a U-shaped clamping plate, a nut, and a screw;

[0013] The side of the U-shaped hot-dip galvanized flat steel is provided with mounting screw holes;

[0014] The U-shaped card plate has a vertical arc groove in the middle and mounting screw holes on both sides;

[0015] After the top of the stainless steel connecting rod is inserted into the arc groove of the U-shaped card plate, the screw is inserted into the mounting screw hole of the U-shaped card plate and the U-shaped hot-dip galvanized flat steel and fixed by the nut.

[0016] Furthermore, the connecting rod is an L-shaped connecting rod, which includes a horizontal rod and a vertical rod. The bottom of the vertical rod has an external thread and is inserted into the threaded hole of the U-shaped hot-dip galvanized flat steel.

[0017] Furthermore, the grounding terminal is connected to the horizontal end of the L-shaped connecting rod, and the grounding terminal is arranged in a horizontal direction for connecting the grounding wire of the equipment.

[0018] Furthermore, four vertical grounding electrodes are provided and installed on the sides of the two longitudinal horizontal poles of the U-shaped hot-dip galvanized flat steel, with two vertical grounding electrodes installed on each longitudinal horizontal pole.

[0019] Furthermore, the spacing between adjacent vertical grounding electrodes is greater than 5 meters.

[0020] Furthermore, the horizontal grounding electrode and the plurality of vertical grounding electrodes are buried below ground level, while the upper part of the L-shaped connecting rod and the grounding terminal are located above ground level.

[0021] Furthermore, the U-shaped plate is made of copper, and the L-shaped connecting rod is made of copper.

[0031] In a specific implementation, Figure 1 The direction of the stainless steel connecting rod 3 and the graphite grounding electrode 2 is defined as vertical, and the plane where the U-shaped hot-dip galvanized flat steel 1 is located is defined as horizontal.

[0032] To address the issue of substandard grounding performance in sections of conventional railways with poor grounding, this invention provides a railway grounding reinforcement device. This device increases the contact points between the grounding device and the earth to enhance the grounding effect. In bridge or roadbed sections with poor grounding, it serves to reinforce the grounding of signal equipment.

[0033] Specifically, such as Figure 1 The device includes a horizontal grounding electrode, multiple vertical grounding electrodes, and a grounding terminal 10.

[0034] The horizontal grounding electrode is a U-shaped hot-dip galvanized flat steel 1, which has two longitudinal horizontal bars and one transverse horizontal bar.

A socket can be provided in the center of the bottom of the stainless steel connecting rod 3, and the graphite grounding electrode 2 can be connected to the bottom of the stainless steel connecting rod 3 by inserting its top into the socket.

[0036] Multiple vertical grounding electrodes are installed on the side of the horizontal grounding electrode using fixing components, and are evenly distributed. Figure 1 In this embodiment, four vertical grounding electrodes are provided and installed on the sides of two longitudinal horizontal bars of the U-shaped hot-dip galvanized flat steel 1, with two vertical grounding electrodes installed on each longitudinal horizontal bar.

[0037] Multiple vertical grounding electrodes are installed on the side of the horizontal grounding electrode using a fixing assembly, evenly distributed. Specifically, the fixing assembly includes a U-shaped clamping plate 4, a nut 5, and a screw rod 6. The side of the U-shaped hot-dip galvanized flat steel 1 has mounting screw holes, and the U-shaped clamping plate 4 has a vertical arc-shaped groove in the middle and mounting screw holes on both sides. After the top of the stainless steel connecting rod 3 is inserted into the arc-shaped groove of the U-shaped clamping plate 4, the screw rod 6 is inserted into the mounting screw holes of the U-shaped clamping plate 4 and the U-shaped hot-dip galvanized flat steel 1 and fixed with the nut 5.

[0038] A screw hole 8 is provided at the top of the horizontal grounding electrode, and the grounding terminal 10 is installed to the top of the horizontal grounding electrode through a connecting rod with external threads.

The grounding terminal 10 is connected to the end of the horizontal rod of the L-shaped connecting rod 9 and is arranged horizontally. During construction, the horizontal grounding electrode and multiple vertical grounding electrodes are buried below ground level, while the upper part of the L-shaped connecting rod 9 and the grounding terminal 10 are located above ground level for connecting the equipment's grounding wire.

[0042] 2. Install all vertical grounding electrodes onto the side of the U-shaped hot-dip galvanized flat steel 1 using fixing components, and maintain a distance of more than 5 meters between two adjacent vertical grounding electrodes.

[0043] 3. Place U-shaped hot-dip galvanized flat steel 1 in the U-shaped trench, and connect all vertical grounding electrodes to form a grounding grid.

[0044] 4. Install the L-shaped connecting rod 9 onto the top of the U-shaped hot-dip galvanized flat steel 1, cover it with soil, and expose the top of the L-shaped connecting rod 9.

[0045] 5. Install grounding terminal 10 on the top of L-shaped connecting rod 9 and connect it to the grounding wire of the equipment to realize the connection between the signal equipment and the grounding device and ensure reliable grounding of the signal equipment.

The grounding effect is significantly better than that of a single grounding electrode. It can be installed simultaneously during the construction phase or modified on existing operating lines. It can be flexibly deployed and effectively ensures the operational safety of railway signaling equipment.
