[0032] The following will further describe this application in detail Figures 1-4 with reference to the accompanying drawings.

[0033] An embodiment of this application discloses a connection structure for a substation cable pipe.

[0034] Referring to Figure 1 and Figure 3 , a connection structure for a substation cable pipe includes a pipe body 1. One side of the pipe body 1 is provided with a connecting pipe 2. One end of the pipe body 1 is fixed with a first fixing sleeve 3, and one end of the connecting pipe 2 is fixed with a second fixing sleeve 4. The first fixing sleeve 3 corresponds to the second fixing sleeve 4. Three symmetric restricting grooves 6 are opened at one end of the first fixing sleeve 3, and a connecting mechanism is arranged between the first fixing sleeve 3 and the second fixing sleeve 4.

[0035] When the substation cable pipe is in use, the staff selects a suitable cable pipe according to the cable to be laid, opens a corresponding installation groove at the place where the cable needs to be laid through the pipe body 1. During installation, the cable and the pipe body 1 are moved into the installation groove, and the multi-pipe body 1 and the connecting pipe 2 are connected and restricted through the restricting mechanism, which improves the installation efficiency, saves installation time, facilitates the operation and installation of the staff, and is convenient for subsequent inspection and maintenance.

[0036] Reference Figures 2-4 , the connecting mechanism includes a limiting frame 5 fixed to one end of the second fixed sleeve 4. There are three limiting frames 5 corresponding to the limiting grooves 6. A fixing groove 7 is formed in the first fixed sleeve 3. The fixing groove 7 corresponds to the limiting groove 6 and the limiting frame 5. A contact block 8 is slidably arranged inside one end of the first fixed sleeve 3. The limiting frame 5 extends into the first fixed sleeve 3 and contacts the contact block 8. A limiting component is arranged between the contact block 8 and the first fixed sleeve 3. The limiting component includes a limiting column 14 fixed in the first fixed sleeve 3. A spring 9 is slidably sleeved on the limiting column 14. The end of the spring 9 is fixedly connected to both the contact block 8 and the first fixed sleeve 3. The limiting column 14 and the contact block 8 are slidably arranged. A connecting column 10 is fixed to one end of the contact block 8 away from the limiting frame 5. The connecting column 10 extends out of the first fixed sleeve 3. A limiting member is arranged between the first fixed sleeve 3 and the connecting pipe 2. The limiting member includes a support pipe 12 fixed to the first fixed sleeve 3. The inner wall of the support pipe 12 is provided with concave threads. The surface of the second fixed sleeve 4 is provided with convex threads 11.

The cushion block 13 corresponds to the first fixed sleeve 3. The cushion block 13 is a flexible rubber pad. The connecting column 10 is a flexible rope. The pipe body 1, the connecting pipe 2, the first fixed sleeve 3, and the second fixed sleeve 4 are all made of stainless steel material.

[0037] When the substation cable pipe is in use, pull the second fixed sleeve 4, so that the second fixed sleeve 4 drives the limiting frame 5 to move, so that the limiting frame 5 enters the limiting groove 6. The limiting frame 5 moves to contact the contact block 8, so that the contact block 8 moves and the spring 9 is compressed. After the contact moves, then rotate the second fixed sleeve 4, so that the limiting frame 5 moves into the fixing groove 7 to limit the limiting frame 5. Through the elastic force of the spring 9, the contact block 8 moves into the limiting groove 6 to limit the limiting frame 5. When the spring 9 expands and contracts, the contact block 8 slides on the limiting column 14 to limit the contact block 8. When the fixed sleeve rotates, the convex threads 11 on the fixed sleeve correspond to the concave threads on the inner wall of the support pipe 12 and rotate and then connect, so that the limiting frame 5 and the contact block 8 move to contact the first fixed sleeve 3, so that the pipe body 1 and the connecting pipe 2 are in close contact, so that the cushion block 13 contacts the first fixed sleeve 3. The cushion block 13 is a flexible rubber pad, which increases the sealing effect. When maintenance is needed, pull the connecting column 10 to drive the contact block 8 to move and the spring 9 expands and contracts, and then rotate the second fixed sleeve 4, so that the limiting frame 5 moves out of the fixing groove 7 and the limiting groove 6 to check and repair the cable inside. The connecting column 10 is a flexible rope, which reduces the situation of accidental touch. The pipe body 1, the connecting pipe 2, the first fixed sleeve 3, and the second fixed sleeve 4 are all made of stainless steel material, which increases the service life. By using the limiting mechanism to connect and limit the multi-pipe body 1 and the connecting pipe 2, the installation efficiency is improved, the installation time is saved, it is convenient for the operation and installation of the staff, and it is convenient for subsequent inspection and maintenance.

The damping plate 15 is a rubber damping plate 15. The surfaces of the pipe body 1 and the connecting pipe 2 are coated with an anti-corrosion layer 16, and the anti-corrosion layer 16 is an epoxy resin anti-corrosion layer 16.

[0039] When the substation cable pipe is used, the shock-absorbing plate 15 is a rubber shock-absorbing plate 15, which is convenient for shock absorption and stability of the pipe body 1 and reduces the harm of vibration to the pipe body 1. The surfaces of the pipe body 1 and the connecting pipe 2 are coated with an anti-corrosion layer 16, and the anti-corrosion layer 16 is an epoxy resin anti-corrosion layer 16, which increases the corrosion resistance of the pipe body 1 and the connecting pipe 2, facilitates the protection of the cable, and reduces the impact on the service life of the pipe body 1 and the connecting pipe 2.

[0041] When the substation cable pipe is used, the fixing sleeve 2 4 is pulled to make the fixing sleeve 2 4 drive the limiting frame 5 to move, so that the limiting frame 5 enters the limiting groove 6, and the limiting frame 5 moves to contact the contact block 8, so that the contact block 8 moves and the spring 9 is compressed. After the contact movement, the fixing sleeve 2 4 is rotated again to make the limiting frame 5 move into the fixing groove 7 to limit the limiting frame 5. The elastic force of the spring 9 makes the contact block 8 move into the limiting groove 6 to limit the limiting frame 5. When the spring 9 is extended and retracted, the contact block 8 slides on the limiting column 14 to limit the contact block 8. When the fixing sleeve rotates, the convex thread 11 on the fixing sleeve and the inner part of the support tube 12 are engaged. The concave threads of the wall are rotated accordingly and then connected, so that the limiting frame 5 and the resistance block 8 move to resist the fixing sleeve 3, so that the pipe body 1 is in close contact with the connecting pipe 2, so that the cushion block 13 is in contact with the fixing sleeve 3, and the cushion block 13 is a flexible rubber cushion to increase the sealing effect. When maintenance is needed, pull the connecting column 10 to drive the resistance block 8 to move the spring 9 to expand and contract, and then rotate the fixing sleeve 2 4 to move the limiting frame 5 out of the fixing groove 7 and the limiting groove 6, and check and repair the cables therein. The connecting column 10 is a flexible rope to reduce the possibility of accidental contact.
