[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0019] Please see Figure 1-6 This utility model provides a technical solution: a terminal cable box for hydraulic turnout switching equipment, including a cable box body 1 and a box cover 2. The bottom end of the cable box body 1 is provided with a recessed cable receiving cavity 16, and the glue-filling port 161 of the recessed cable receiving cavity 16 is smaller than its cavity cross-section. The bottom end of the recessed cable receiving cavity 16 is provided with a cable inlet hole 162, and a wire-passing hole 19 is provided on one side wall of the cable box body 1. After the cable passes through the cable inlet hole 162 into the recessed cable receiving cavity 16, glue is then injected into the entire recessed cable receiving cavity 16 through the glue-filling port 161 to seal it. This ensures the insulation, waterproofing, and dustproofing of each signal cable in the recessed cable receiving cavity 16. Furthermore, since the glue-filling port 161 is smaller than the recessed cable receiving cavity 16, the effective volume capacity inside the cable box body 1 is increased, and the volume of the cable box is reduced.

[0020] On the bottom plate of the cable box 1, a half-wave rectifier box 6, an information acquisition box 7, and multiple terminal blocks 5 are fixed by screws around the sunken cable receiving cavity 16.

[0021] The right side of the cover 2 is provided with a connecting protrusion 21, and the outer end of the connecting protrusion 21 has a U-shaped notch. The left side of the cover 2 is fixed with a fastening plate 22, and the fastening plate 22 has vertically opened bolt holes 221. The right side wall of the cable box 1 is provided with a double-ear hinge support 11 at the corresponding U-shaped notch. The double-ear hinge support 11 is connected to a hinge bolt 12 that can be vertically rotated into the U-shaped notch by a pin. The top of the hinge bolt 12 is screwed with a locking nut 13. By screwing the locking nut 13, its bottom abuts against the connecting protrusion 21 of the cover 2, thereby abutting the right side of the cable box 1 and the cover 2. Fastening: A fixed support 14 is provided on the left side wall of the cable box 1. The fixed support 14 is provided with a vertically arranged fastening bolt 3 and a rotating shaft 4. The end of the fastening bolt 3 passes through the fixed support 14 and the bolt hole 221, and a locking nut 31 is screwed to the end of the fastening bolt 3. By tightening the locking nut 31, the left side of the cable box 1 and the cover 2 are fixed to each other. In this embodiment, the cable box 1 and the cover 2 can be fastened to each other by the cooperation of the fastening bolt 3 and the locking nut 31 and the cooperation of the hinge bolt 12 and the locking nut 13. The cable box 1 and the cover 2 are easy to disassemble and assemble.

[0022] Both ends of the rotating shaft 4 pass through the fixed support 14. The top end of the rotating shaft 4 is fixedly connected to the fastening plate 22. A weight-reducing spring 41 is sleeved on the rotating shaft 4 between the fastening plate 22 and the fixed support 14. In this embodiment, the weight of the cover 2 is slightly greater than the elastic force of the weight-reducing spring 41. The bottom end of the rotating shaft 4 is provided with a cotter pin 42 for axial sliding limit. A vertically arranged abutment support plate 15 is provided on the fixed support 14 at the outer end of the rotating shaft 4. The top end of the abutment support plate 15 is higher than the cover 2. After the cover 2 is raised and rotated, it can be placed on the abutment support plate 15. When the cable box is inspected, it can be repaired by screwing... After loosening the locking nut 13 to disengage it from the cover 2 and removing the fastening bolt 3, remove the cover 2. Lift the cover 2 upwards, and the rotating shaft 4 rises along with the cover 2. When the height of the cover 2 is higher than the abutting support plate 15, rotate the cover 2 along the rotating shaft 4 to above the abutting support plate 15. Lower the cover 2 so that it abuts against the abutting support plate 15, separating the cable box 1 from the cover 2 without separating them. After maintenance is completed, raise the cover 2 a short distance, then rotate the cover 2 to directly above the cable box 1. Lower the cover 2 and then interlock it with the cable box 1. This makes cable box maintenance more convenient and shortens maintenance time.

[0023] A first cable protection pipe 9 is welded to the outer wall of the cable box 1 at the position corresponding to the cable hole 19. A second cable protection pipe is welded to the recessed cable receiving cavity 16 at the position corresponding to the cable inlet hole 162. Both the first cable protection pipe 9 and the second cable protection pipe are flanged pipe structures. A double-hole fixing plate 18 for connecting to a cement foundation is fixed at the bottom of one side wall of the cable box 1. The first cable protection pipe 9 and the second cable protection pipe protect the cables at the cable hole 19 and the cable inlet hole 162, respectively, and improve the waterproof performance of the cable box.

[0024] The cable box body 1, box cover 2, wire protection tube 1 9 and wire protection tube 2 are all made of steel plate, and the outer surfaces of the cable box body 1, box cover 2, wire protection tube 1 9 and wire protection tube 2 are all provided with a hot-dip galvanized layer 10. The cable box is lightweight, easy to transport, has good corrosion resistance, and a long service life.

[0025] The bottom plate of the cable box 1 is provided with a drainage hole 17 located around the recessed cable receiving cavity 16. The drainage hole 17 is a screw hole structure, and a sealing bolt 8 is threaded into the drainage hole 17. When floods occur, water enters the cable box 1. The water inside the cable box 1 is quickly drained by removing the sealing bolt 8. After the water inside the cable box 1 is drained, the sealing bolt 8 is installed in the drainage hole 17 to ensure the sealing of the cable box.

[0026] The terminal cable box for hydraulic turnout switching equipment disclosed in this embodiment has a recessed cable accommodating cavity 16 with a glue-filling port 161 smaller than its cross-section, which increases the effective volume capacity inside the cable box 1 and reduces the size of the cable box. The cable box is lightweight, easy to transport, has good corrosion resistance, and a long service life. The cable box 1 and the cover 2 are easy to disassemble and assemble. When the cable box is under maintenance, the cover 2 can be disassembled, lifted, and rotated so that the cover 2 rotates along the rotation axis 4 to abut against the support plate 15, so that the cable box 1 and the cover 2 are separated but not separated. After the maintenance is completed, the cover 2 is rotated again to make it interlock with the cable box 1, making the cable box maintenance more convenient and shortening the maintenance time. The cable box is lightweight, easy to transport, has good corrosion resistance, and a long service life. In case of flood, the water inside the cable box 1 can be quickly drained by removing the sealing bolts 8.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
