Description

Technical Field

[0001] The present invention relates to the technical field of power cables, and in particular to a cable accessory installation protection device. Background Art

[0002] Cable accessories are required for connection in power systems. The installation quality of cable accessories is directly related to the safety and stability of power transmission. As power grid construction develops towards complexity and intelligence, the technical challenges faced by cable accessory installation are becoming increasingly prominent. Existing technologies have the following core defects: Traditional cable accessory installation devices mostly use fixed bases. When there is a height difference in the installation site, the device is prone to tilting or partially hanging, resulting in uneven force on the cable accessories and causing mechanical damage to the insulation layer. Existing protective devices mostly use a single sealing structure. Furthermore, the fixing bolts are easily loosened after vibration, which leads to gaps in the sealing structure. Sand and dust particles can enter the interior of the accessory through the gaps, forming a conductive path. During the rainy season, rainwater seepage can cause the insulation material to become damp. The connectors used to connect traditional cables and accessories are basically secured with bolts and lock nuts, which makes it difficult to disassemble and assemble the cables and accessories during maintenance. In addition, the small contact area between the cables and accessories can easily lead to heat loss at the connectors, thereby shortening the life of the cable and accessory connections.

In addition, the side contact design between the conductive rod and the first reinforcement sleeve increases the contact area three times that of the traditional threaded connection, reducing heat loss at the joint.

[0020] The locking frame cooperates with the locking block to quickly lock the height of the bottom protective shell under the pressure of the spring. The operator can unlock the bottom protective shell by pressing the locking frame in the reverse direction. At this time, the bottom protective shell can be adjusted in height as needed.

The split setting of the bottom protective shell 4 and the adjustment plate 401 is convenient for selective assembly according to needs. A group of anti-loosening blocks are provided above the locking frame 3, and the anti-loosening blocks are aligned with the bolt connection sleeves. Therefore, the locking frame 3 cooperates with the anti-loosening blocks to prevent the locking bolts from loosening to prevent the bolts from loosening. , Therefore, the split design of the bottom protective shell 4 and the adjusting plate 401 combined with the firm connection of the locking bolts is convenient for production, processing and transportation, and the anti-loosening block applies continuous pressure to the bolts, effectively preventing the bolts from loosening due to long-term vibration or temperature changes, thereby extending the service life of the device.

Two sliding holes are opened at the upper position on one side of the upper anti-loosening shell 5, and the third positioning rod 601 passes through the inside of the sliding hole. A supporting spring and a retaining spring are installed at the outer position of the anti-loosening frame 6. The supporting spring elastically supports the anti-loosening frame 6 to one side, so that the anti-loosening frame 6 is reset to quickly prevent the locking bolts of the upper anti-loosening shell 5 from loosening, and prevent the bottom protective shell 4 and the upper anti-loosening shell 5 from loosening and creating gaps.

The first reinforcement sleeves 702 and the fourth positioning rods 703 are an integrated structure. The fourth positioning rods 703 cooperate with the positioning ear plates 402 to circumferentially position and support a group of first reinforcement sleeves 702, so that the first reinforcement sleeves 702 can move stably laterally when subjected to force. A conductive rod 701 is installed between the two first reinforcement sleeves 702 in the same direction. The two sides of the conductive rod 701 extend to the interior of the first reinforcement sleeve 702 respectively.

The conductive rod 701 and the first reinforcement sleeve 702 are electrically connected through side contact. The conductive rod 701 and the first reinforcement sleeve 702 cooperate with each other to form a conductive structure 7. Therefore, when the conductive rod 701 and the first reinforcement sleeve 702 are electrically connected through side contact, the high current transmission requirement is met.

Therefore, the open groove design of the second reinforcement sleeve 901 is convenient for rapid assembly with the cable 9, and is electrically connected to the conductive rod 701 through the end face, thereby realizing reliable conduction of the disconnected cable 9. This structure simplifies the wiring process, reduces contact resistance, and improves the stability of power transmission. Qualitatively, two symmetrically distributed extrusion plates 502 are provided on both sides of the inner side of the upper protective shell 5, and an inclined surface is provided on one side of the extrusion plate 502. When the upper protective shell 5 and the bottom protective shell 4 are assembled, the extrusion plate 502 squeezes the first reinforcement sleeve 702 to both sides, so that the first reinforcement sleeve 702 moves to the outside of the cable 9 to avoid unstable contact of the cable 9. After the upper protective shell 5 is removed, the first reinforcement sleeve 702 moves inward under the push of the spring, which facilitates the installation and removal of the cable 9. Therefore, when the upper protective shell 5 is assembled with the bottom protective shell 4, the inclined surface of the extrusion plate 502 pushes the first reinforcement sleeve 702 to the outside of the cable 9 through mechanical transmission, so as to achieve close contact between the conductive structure 7 and the cable 9 and ensure the stability of the electrical connection; and the automatic reset design of the first reinforcement sleeve 702 during disassembly significantly improves the convenience of inspection and maintenance.

[0028] Example 2, based on Example 1, Figure 1-Figure 7 As shown, according to actual needs, the bottom support plate 1, the anchor mechanism 2, and the adjustment plate 401 are removed where the cable 9 does not need support. When the cable 9 needs support and protection, the bottom support plate 1, the anchor mechanism 2, and the adjustment plate 401 are reassembled to the bottom of the bottom protective shell 4, and the cable 9 is supported and protected by the anchor mechanism 2.

[0029] Example 3, based on Example 1, Figure 1-Figure 7 As shown, the model of the insulating sealing seat 501 is selected to correspond to the model of the cable 9.

[0030] The working principle of this embodiment is as follows: Place the bottom support plate 1 at the installation position, adjust the horizontality through the anchor mechanism 2, rotate the threaded rod 201, and drive the threaded connection sleeve 202 to move vertically until the stabilizing plate 204 is completely in contact with the ground, and lock the rotation position of the threaded rod 201 with the positioning bolts; Insert the adjustment plate 401 into the sliding groove of the bottom support plate 1 and adjust it to the target height in the vertical direction. Press the locking frame 3 to make the locking block embed into the locking groove of the adjustment plate 401, quickly fix the height of the bottom protective shell 4, pass the cable 9 through the inside of the protective sleeve 8, install the second reinforcement sleeve 901, and wrap the outside of the cable 9 through the open groove to ensure that the end face is in close contact with the conductive rod 701 to form an electrical connection. Push the first reinforcement sleeve 702 to move horizontally along the fourth positioning rod 703 so that the two ends of the conductive rod 701 are inserted into the inside of the first reinforcement sleeve 702, and a conductive connection is achieved through side contact; Insert the insulating sealing seat 501 into the positioning grooves of the bottom protective shell 4 and the upper protective shell 5, ensure that the positioning ring of the protective sleeve 8 is stuck in the sealing groove to form a sealing structure, cover the upper protective shell 5, and preliminarily fix it with bolts. The anti-loosening frame 6 resets the clamping bolts and maintains the anti-loosening state through the support spring. Fully tighten the connecting bolts of the upper protective shell 5 and the bottom protective shell 4. At this time, the inclined surface of the extrusion plate 502 pushes the first reinforcement sleeve 702 to move toward the outside of the cable 9 to ensure close contact between the conductive structure 7 and the cable 9; Press the anti-loosening frame 6 to release the lock of the bolt, remove the upper anti-loosening shell 5, maintain the cable 9 and accessories, remove the second reinforcement sleeve 901 and accessories, take out the old cable 9 and accessories, and install the new cable 9 and accessories in the reverse process; Press the locking frame 3 in reverse to unlock the bottom protective shell 4. At this time, adjust the height of the bottom protective shell 4 and the cable 9. When the cable 9 does not need support, remove the bottom support plate 1, the anchor mechanism 2 and the adjustment plate 401, and directly fix the bottom protective shell 4 to the bracket. Through the above steps, the efficient installation and reliable protection of the cable 9 accessories can be achieved, significantly improving the safety and stability of the power connection.
