Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated high-voltage switchgear cabinets, and more specifically, it relates to a prefabricated high-voltage switchgear cabinet. Background Technique

[0002] In the existing technology, during the assembly process of prefabricated high-voltage switchgear cabinets, there are certain limitations in the fixing and disassembling operations of the mounting plate, which directly affects the usability of the mounting plate. First of all, when assembling the existing prefabricated high-voltage switchgear cabinets, the fixing of the mounting plate usually requires the use of bolts or other fasteners. This fixing method not only takes a lot of time and labor, but also in actual operation, due to the limited space inside the switchgear cabinet, it is often difficult for the operator to directly access the fastening points behind the mounting plate, resulting in a cumbersome and inefficient installation process. In addition, frequent disassembly and reinstallation may damage the mounting plate or fasteners, further reducing the usability of the mounting plate.

[0003] Secondly, when it is necessary to disassemble the mounting plate for maintenance or replacement, the existing prefabricated high-voltage switchgear cabinets often face the same problem. Due to the design limitations of the fixing method, disassembling the mounting plate usually requires the use of specific tools and needs to be operated according to specific steps. This not only increases the difficulty of disassembly and prolongs the maintenance time, but also in case of emergency, this cumbersome disassembly process may delay the timely repair of the switchgear cabinet, thus affecting the stability and safety of the entire power system.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the present utility model provides a prefabricated high-voltage switchgear cabinet, which has the following

[0017] beneficial effects:

[0018] 1. The design of the fixing mechanism enables the mounting plate of the prefabricated high-voltage switchgear cabinet to be fixed conveniently and quickly. Through the cooperation of the mounting plate, the fixed sleeve, the fixed rod and the spring, the operator can easily slide the mounting plate onto the fixed rod and provide a fixing force through the compression of the spring. This design not only simplifies the fixing process, but also ensures the stability of the mounting plate through the limiting mechanism of the spiral strip and the spiral groove. The reverse pushing action of the spring enables the fixed sleeve to have a self-locking function, further enhancing the fixing stability and improving the convenience of use of the mounting plate.

[0019] 2. The clamping mechanism realizes the efficient clamping between the mounting plate and the fixing rod through the cooperation of the slider, compression spring and variable-diameter sleeve. The setting of the compression spring provides additional clamping force, and the design of the slider makes the clamping process adjustable to adapt to mounting plates of different thicknesses. Through the mechanism of the adjusting ring and the pulling rope, the operator can easily release the clamping, thus facilitating the disassembly of the mounting plate. This clamping mechanism not only improves the operation convenience but also ensures the protection of the internal components of the distribution cabinet during the disassembly process.

[0020] 3. The follow-up mechanism provides a flexible adjustment means for the operator through the cooperation of the pulling rope and the adjusting ring. The operator can pull the adjusting ring to drive the pulling rope and the slider to move, thereby adjusting the clamping force and releasing the clamping state. This design makes the fixing and disassembly processes of the mounting plate simpler, reduces the maintenance time, and improves the overall use efficiency of the distribution cabinet.

[0030] Please refer to Figures 1-5 , a prefabricated high-voltage power distribution cabinet, including a cabinet body 1, a fixing mechanism is arranged on the cabinet body 1, the fixing mechanism includes a mounting plate 2, a fixing sleeve 3, a fixing rod 4, a spring 5, a clamping mechanism, a fitting plate 6, a spiral strip 7 and a follow-up mechanism. There are multiple fixing rods 4, and the multiple fixing rods 4 are respectively installed on the cabinet body 1. The mounting plate 2 is slidably connected to the multiple fixing rods 4. The fixing sleeve 3 is slidably connected to the fixing rod 4. A spring 5 is installed on the fixing sleeve 3, and the spring 5 abuts against the mounting plate 2. The clamping mechanism is cooperatively connected to the fixing sleeve 3 and the fitting plate 6. A fitting groove 8 is formed on the fitting plate 6, and the fitting groove 8 abuts against the side wall of the fixing rod 4. A spiral groove 9 is formed on the side wall of the fixing rod 4, and a spiral strip 7 is installed in the fitting groove 8, and the spiral strip 7 abuts against the spiral groove 9. The follow-up mechanism is installed in the fixing sleeve 3. A fillet 10 is formed on the fixing rod 4. The clamping mechanism includes a slider 11 and a compression spring 12. There are multiple compression springs 12, and both ends of the multiple compression springs 12 are respectively connected to the fitting plate 6 and the slider 11. A variable-diameter sleeve 13 is arranged in the fixing sleeve 3, and the slider 11 is slidably connected to the variable-diameter sleeve 13. A top sleeve 14 is arranged at the upper end of the fixing sleeve 3, and the fixing rod 4 is slidably connected in the top sleeve 14. An insertion hole 15 is formed on the lower end surface of the fixing sleeve 3, and the fixing rod 4 is slidably connected in the insertion hole 15. There are multiple sliders 11, and multiple push springs 16 are respectively arranged on the multiple sliders 11, and the multiple push springs 16 abut against the top sleeve 14. The follow-up mechanism includes a pull rope 17 and an adjusting ring 18.

[0031] In this embodiment, when it is necessary to fix the mounting plate 2, first slide the mounting plate 2 on a plurality of fixing rods 4, then slide the fixing sleeve 3 on the fixing rods 4, and then compress the spring 5. The spring 5 provides a fixing force for the mounting plate 2 and applies a reverse thrust to the fixing sleeve 3. Since the spiral strip 7 on the fitting plate 6 abuts against the spiral groove 9, the fitting plate 6 and the fixing rod 4 can be limited. Then pull the adjusting ring 18 to make the slider 11 slide downward, and then make the fitting plate 6 and the fixing rod 4 clamp and fit, thus ensuring the stability of the fixation. Under the reverse pushing action of the spring 5, the slider 11 has a contracting state. When the slider 11 contracts, the fitting plate 6 abuts against the fixing rod 4, so self-locking can be formed, thus ensuring the stability of the fixation.

[0032] More specifically, when it is necessary to unlock, first rotate along the spiral groove 9 to move upward, thereby reducing the elastic force of the spring 5, and thus reducing the friction between the fitting plate 6 and the fixing rod 4. Then drive the slider 11 to pull upward through the pull rope 17 on the adjusting ring 18, thereby unlocking the clamping connection between the fitting plate 6 and the fixing rod 4, and then completing the adjustment process.

[0033] In summary, when the overall device is in use or operation: when it is necessary to fix the mounting plate 2, first slide the mounting plate 2 on a plurality of fixing rods 4, then slide the fixing sleeve 3 on the fixing rods 4, and then compress the spring 5. The spring 5 provides a fixing force for the mounting plate 2 and applies a reverse thrust to the fixing sleeve 3. Since the spiral strip 7 on the fitting plate 6 abuts against the spiral groove 9, the fitting plate 6 and the fixing rod 4 can be limited. Then pull the adjusting ring 18 to make the slider 11 slide downward, and then make the fitting plate 6 and the fixing rod 4 clamp and fit, thus ensuring the stability of the fixation. Under the reverse pushing action of the spring 5, the slider 11 has a contracting state. When the slider 11 contracts, the fitting plate 6 abuts against the fixing rod 4, so self-locking can be formed, thus ensuring the stability of the fixation.

[0034] When it is necessary to unlock, first rotate along the spiral groove 9 to move upward, thereby reducing the elastic force of the spring 5, and thus reducing the friction between the fitting plate 6 and the fixing rod 4. Then drive the slider 11 to pull upward through the pull rope 17 on the adjusting ring 18, thereby unlocking the clamping connection between the fitting plate 6 and the fixing rod 4, and then completing the adjustment process.
