Technical Field
[0001] The utility model relates to the technical field of through-ground wires, in particular to a railway through-ground wire cutting-proof casing. Background Art
[0002] The railway through-ground wire is a grounding system that connects the traction power supply return system, power supply system, signal system, communication and other electronic information systems, buildings, roadbed, platform, bridge, tunnel, sound barrier and other devices that need to be grounded along the railway through the through-ground wire. At the same time, the through-ground wire is also a main loop of traction return. In principle, it is actually a common grounding system and forms an equipotential body of the railway through equipotential connection. With the development of high-speed railways, the traction load of the railway has increased, and the return current of the traction substation has also increased. The grounding system of the traction substation faces two serious problems: the first problem is that the return current causes the ground grid potential to be unequal. This situation will threaten the safety of people and equipment on the one hand, and on the other hand, it will affect the protection, measurement, and signal devices, and may cause the protection device to malfunction or refuse to operate. The second problem is that the bus current fluctuation increases due to the operation of starting and braking when the locomotive is running. The electromagnetic signal generated by this fluctuation will interfere with the signal and communication circuit in the substation, and will also interfere with the measurement signal of the protection device and affect the communication between the dispatching center and the substation. The general grounding system cannot meet the requirements for electromagnetic signal shielding. Due to these problems in the traditional grounding system, with the development of the integrated automation system of the traction substation, these problems have become more serious, so the development of the integrated grounding system has become an inevitable trend.
[0003] A Chinese patent discloses a sleeve, the publication number of which is CN204585068U. The sleeve is provided in a sleeve body with a protective sleeve, which is fixedly connected to the sleeve body. The inner surface of the protective sleeve matches the outer surface of the fastener, and can play the role of installing the fastener. During installation, the sleeve body can avoid direct contact with the fastener head, effectively alleviate the wear of the sleeve body and the fastener head, and improve the service life of the sleeve body and the fastener, saving costs.
[0004] The outer shell of the casing is relatively sturdy. During long-term use, it is made of relatively sturdy materials. When the outer shell is in contact with the ground, it is easy to be damaged due to wear and tear over a long period of time. At the same time, there is a gap in the contact part of the pipe, and rainwater will enter the interior, affecting the internal working conditions of the casing. Utility Model Content

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] like Figure 1-4As shown, this embodiment proposes a railway through-ground wire anti-cut casing, including a soft casing assembly 1. Through the setting of the soft casing assembly 1, the ground wire can be placed inside when in use. The soft casing assembly 1 includes an outer hose 101. Through the setting of the outer hose 101, the ground wire can be placed outside when in use. The inner hose 103 is sleeved inside the outer hose 101. Through the setting of the inner hose 103, the bottom line can be placed inside when in use. A gap is formed between the outer hose 101 and the inner hose 103. Through the setting of the gap, the anti-cut wire mesh 102 can be set inside when in use. The anti-cut wire mesh 102 is set in the gap. Through the setting of the anti-cut wire mesh 102, when the outer hose 101 is damaged, the anti-cut wire mesh 102 can avoid being cut when in use.
[0026] Both ends of the soft sleeve assembly 1 are plugged with connecting rings 2. Through the setting of the connecting rings 2, the functions of different setting parts can be achieved when in use. The outer sides of the connecting rings 2 are fixedly connected with threaded parts 3. Through the setting of the threaded parts 3, the function of facilitating the connection of two different connecting rings 2 with threaded rods can be achieved when in use.
[0027] One side of one of the connecting rings 2 is provided with a snap-in groove 4, through the setting of the snap-in groove 4, the plug-in ring 5 can be placed inside the snap-in groove 4 when in use, and one side of the other connecting ring 2 is fixedly connected with a plug-in ring 5, through the setting of the plug-in ring 5, the snap-in groove 4 can be plugged in when in use, and one side of the plug-in ring 5 is fixedly connected with an isolating ring 6, through the setting of the isolating ring 6, the gap between the plug-in ring 5 and the snap-in groove 4 can be filled when in use, and the material of the isolating ring 6 is soft rubber.
[0028] The outer annular array of the connecting ring 2 has a plurality of threaded members 3, and the bottom of the connecting ring 2 is fixedly connected with a support member 7. The setting of the support member 7 can support the device to stand on the ground when in use.
[0029] One side of the connecting ring 2 is connected with a connecting sleeve 8. Through the arrangement of the connecting sleeve 8, the connecting ring 2 can be plugged into the mounting ring 9 when in use.
