Description

Technical Field

[0001] The utility model relates to the technical field of a connection cabinet for high-voltage electric energy transmission, and more particularly to a connection cabinet for high-voltage electric energy transmission. Background Art

[0002] Under current technical conditions, high-voltage power transmission connection cabinets face certain technical challenges in their specific application. First, due to the particularity of high-voltage power transmission, the diameter of the cables required for connection is usually large, which means that the weight and volume of the cables themselves are also relatively large. When such thick cables are connected to the connection cabinet, higher requirements are placed on the fixation of the cabinet. However, the physical properties of such cables are often not fully considered during the design and manufacture of existing connection cabinet equipment, resulting in an unstable connection between the cable and the cabinet. This loose fixation not only affects the overall appearance of the equipment, but more importantly, it may bring potential safety risks. During the operation of the power system, if the cable connection point is displaced or falls off due to loose fixation, it may cause an electrical accident, posing a threat to the safety of equipment and personnel.

[0003] Furthermore, existing equipment fails to effectively secure the high-voltage cables to the cabinet, directly impacting the safety of the interconnector cabinet. Safety is a paramount consideration in power system operation. If the interconnector cabinet fails to ensure a stable connection of the high-voltage cables, it can cause problems such as overheating of the cable connectors and insulation damage. These problems not only shorten the equipment's service life but can also lead to serious consequences such as fires. Utility Model Content

[0005] In view of the problems existing in the prior art, the utility model provides a connection cabinet for high-voltage electric energy transmission to solve the technical problems mentioned in the background technology.

[0006] (2) Technical solution

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a communication cabinet for high-voltage electric energy transmission, comprising a cabinet body, which is installed on external equipment, and a fixing mechanism is provided on the cabinet body, wherein the fixing mechanism comprises a fixing sleeve, a conical sleeve, a clamping mechanism, a positioning block, a hexagonal sleeve, a synchronization plate and a receiving mechanism, wherein the fixing sleeve is installed in the cabinet body, a transmission component is provided in the cabinet body, the transmission component is electrically connected to the cable, the fixing sleeve is installed on the cabinet body, the clamping mechanism is cooperatively connected to the fixing sleeve and the conical sleeve, the positioning block is installed on the conical sleeve, the hexagonal sleeve is installed at both ends of the conical sleeve, the positioning block is installed on the conical sleeve, a positioning hole is opened on the synchronization plate, the positioning hole is slidably connected to the positioning block, and the receiving mechanism is installed on the fixing sleeve.

[0008] The utility model is further configured such that a plurality of the fixing sleeves are provided, and a synchronization plate is installed between every two of the fixing sleeves, and each synchronization plate is provided with a handle. This design allows the operator to operate the plurality of handles simultaneously to achieve synchronous action of the plurality of conical sleeves.

[0009] The utility model is further configured such that springs are provided on the hexagonal sleeves on both sides, and the springs on both sides respectively abut against the two ends of the synchronization plate. The setting of such springs can automatically clamp the positioning holes on the synchronization plate and the positioning blocks after the handle is loosened, thereby ensuring the stable positioning of the tapered sleeves and enhancing the reliability of the entire fixing system.

[0010] The utility model is further configured such that the clamping mechanism includes a follower block, a contraction groove is provided on the side wall of the fixing sleeve, and the follower block is slidably connected in the contraction groove. The sliding connection of the follower block in the contraction groove allows precise control of the fixing force of the cable, and adapts to different cables by contraction or relaxation, thereby improving the adaptability of the fixing system.

[0011] The utility model is further configured such that spiral strips are symmetrically provided on the inner wall of the conical sleeve, and the side walls of the follower block are engaged with the spiral strips. The arrangement of the spiral strips enables the follower block to firmly fix the cable through spiral motion when sliding, thereby increasing the gripping force of the fixing mechanism on the cable.

[0012] The utility model is further configured such that each of the following blocks is provided with an inclined plate, and a plurality of inclined grooves are provided on the side wall of the fixing sleeve. The inclined plates are slidably connected in the inclined grooves. The cooperation between the inclined plates and the inclined grooves enables the following block to adaptively adjust along the contour of the cable when sliding, thereby ensuring uniform fixation of the cable over the entire length.

[0013] The utility model is further configured such that a plurality of transverse bars are provided on the side wall of each follower block, and each of the transverse bars respectively contacts the side wall of the cable. These transverse bars can directly contact the cable to provide multi-point support, effectively disperse the weight of the cable, and prevent the cable from being damaged due to excessive local pressure.

[0014] The utility model is further configured such that the receiving mechanism includes a receiving sleeve, the receiving sleeves are respectively installed at the upper and lower ends of the fixing sleeve, the hexagonal sleeve is slidably connected to the receiving sleeve, and the installation of the receiving sleeve enables the hexagonal sleeve to slide smoothly, thereby dispersing the pressure during the fixing process.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the present invention provides a high-voltage power transmission connection cabinet, which has the following beneficial effects:

[0017] 1. The design of the fixing mechanism ensures that the high-voltage cable can be firmly installed in the cabinet, avoiding potential safety risks caused by cable movement. The combination of the fixing sleeve and the conical sleeve, as well as the application of the positioning block and the hexagonal sleeve, can effectively maintain the stable position of the cable in the cabinet. The handle on the synchronization plate allows the operator to manually compress the spring, so that the positioning hole leaves the positioning block, thereby loosening and fixing the conical sleeve. This design makes the installation and removal of the cable easy, while ensuring the stability during the power transmission process, and improving the safety and reliability of the overall equipment.

[0018] 2. The clamping mechanism achieves precise fixation of the cable through the cooperation of the follower block and the shrinkage groove, as well as the engagement with the spiral strips on the inner wall of the tapered sleeve. The inclined plate on the follower block slides into the inclined groove of the fixing sleeve, and the transverse strips abut against the side wall of the cable. This design causes the cable to be subjected to uniform pressure at multiple points, ensuring the cable's fixation effect. The effective operation of the clamping mechanism not only improves the reliability of cable fixation, but also provides additional protection when the cable is subjected to external force, reducing wear or damage caused by cable movement.

[0019] 3. The receiving mechanism consists of a receiving sleeve, which is installed at the upper and lower ends of the fixing sleeve and is slidably connected to the hexagonal sleeve. This design ensures the stability of the conical sleeve by sliding between the receiving sleeve and the hexagonal sleeve when fixing the cable, thereby ensuring the stability of the cable fixation.

Each synchronous plate 6 is provided with a handle 9, and springs 10 are provided on the hexagonal sleeves 5 on both sides. The springs 10 on both sides respectively abut against the two ends of the synchronous plate 6. The clamping mechanism includes a follower block 11, and a contraction groove 12 is provided on the side wall of the fixed sleeve 2. The follower block 11 is slidably connected in the contraction groove 12.

[0030] In this embodiment, when the cable needs to be fixed, the corresponding handle 9 needs to be pushed first to compress the spring 10, and then the positioning hole 8 on the synchronization plate 6 is separated from the positioning block 4. At this time, the two conical sleeves 3 are in a loose state, and then the spiral strip 13 can be rotated by driving the rotation of the hexagonal sleeve 5, and the follower block 11 is engaged with the follower strip, thereby driving the follower block 11 to slide along the contraction groove 12, and then the transverse strip 16 is abutted against the side wall of the cable.
