Description

Technical Field

[0001] This utility model relates to the field of power auxiliary equipment technology, specifically a portable transformer substation power outage and restoration control lever. Background Technology

[0002] Based on the experience of power distribution network operation in recent years, firstly, most transformer area faults are caused by overload tripping of switches in low-voltage distribution boxes, requiring power restoration operations; secondly, low-voltage lines are de-energized during line maintenance, requiring operation of low-voltage disconnect switches and load switches; and thirdly, when line renovation involves de-energizing low-voltage lines, low-voltage disconnect switches and load switches need to be operated.

[0003] Currently, some outdoor transformer substations are mounted on utility poles. Due to their overhead design, operators need to use long operating rods to control power supply and shutdown operations. However, these long rods are inconvenient to carry when operators are out and about, while shorter rods have significant limitations in use, causing inconvenience for operators in power supply and shutdown work. Therefore, a portable transformer substation power supply and shutdown operating rod is proposed. Utility Model Content

Detailed Implementation

[0020] 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.

[0021] Please see Figure 1-3 This utility model provides a technical solution: a portable transformer substation power outage and restoration operating lever, including a lower lever body 1, a middle lever body 2, an upper lever body 3, a pull hook 4, a fixing rope 5, and a tightening mechanism 6. The lower lever body 1, the middle lever body 2, and the upper lever body 3 are sequentially connected from bottom to top. The lower lever body 1 is provided with a tightening mechanism 6 at its bottom. The tightening mechanism 6 includes a rotating handle 7, a lead screw 8, and a telescopic block 9. The rotating handle 7 is located at the bottom of the lower lever body and is rotatably connected to the lower lever body 1. The center of the rotating handle 7 is fixedly connected to the lead screw 8. The telescopic block 9 is embedded in the lower lever body 1 and is slidably connected to the lower lever body 1. The lead screw 8 is threadedly connected to the telescopic block 9. The top of the telescopic block 9 is connected to the lower end of the fixing rope 5. The upper end of the fixing rope 5 passes through the middle lever body 2 and is connected to the upper lever body 3. The end of the upper lever body 3 is fixedly connected to the pull hook 4.

[0022] In a further improvement, the middle rod 2 has at least one section, and the center of the middle rod 2 has a center hole 10. By having at least one section of the middle rod 2, the number of middle rods 2 can be easily adjusted according to the usage requirements of different lengths, thus satisfying the convenience of using different lengths.

[0023] In a further improvement, one end of the middle rod 2 is provided with a plug-in groove 11, and the other end of the middle rod 2 is provided with a tapered plug-in end 12. By providing plug-in grooves 11 and plug-in ends 12 at both ends of the middle rod 2, it is convenient to plug and connect multiple sections of the middle rod 2 end to end, thereby improving the stability of the operating rod after connection.

[0024] Further improvements include a non-slip sleeve 13 fitted onto the surface of the lower rod body 1. The surface of the non-slip sleeve 13 is provided with uniformly distributed non-slip grooves 14. By fitting the non-slip sleeve 13 onto the surface of the lower rod body 1, the stability and comfort of using the operating rod are improved.

[0025] In a further improvement, the telescopic block 9 has an embedded hole 15 at its center, and a threaded bushing 16 is embedded and connected inside the embedded hole 15. By having the threaded bushing 16 embedded and connected at the center of the telescopic block 9, it is convenient to rotate and connect with the lead screw 8, and it is convenient to push the telescopic block 9 to slide up and down.

[0026] Specifically, the telescopic block 9 has symmetrically distributed limiting grooves 17 on its side wall, and the lower rod body 1 has a protruding limiting strip 18 on its inner wall. The limiting strip 18 is slidably connected to the limiting groove 17. The limiting strip 18 on the inner wall of the lower rod body 1, together with the limiting groove 17 on the side wall of the telescopic block 9, facilitates the restriction of the telescopic block 9 from rotating inside the lower rod body 1, and facilitates the telescopic movement in conjunction with the rotation of the lead screw 8.

[0027] In use, the lower rod 1, middle rod 2, and upper rod 3 are connected sequentially, and the insertion slot 11 and insertion end 12 are interlocked to improve the stability of the rod connection. Then, the rotating handle 7 at the bottom of the lower rod 1 is manually rotated to drive the telescopic rod downward along the limiting strip 18, tightening the internal fixing rope 5 to prevent the multi-section combined operating rod from disengaging during use. After use, the rotating handle 7 is rotated in the opposite direction to loosen the internal fixing rope 5, and the lower rod 1, middle rod 2, and upper rod 3 are manually separated and folded for easy carrying by the operator, improving the convenience and flexibility of use.

[0028] This invention addresses the problem that some outdoor transformer substations are mounted on utility poles. Due to their overhead design, operators need to use long operating rods when power is cut off or restored. However, long operating rods are inconvenient to carry when operators are out, while shorter operating rods have significant limitations in use, causing inconvenience for operators. This invention utilizes a lower pole body 1, a middle pole body 2, an upper pole body 3, a switch hook 4, a fixing rope 5, and a tightening mechanism 6 to form a power cutting and restoration operating rod. This allows for easy folding of the operating rod, greatly shortening its length for carrying, making it convenient for operators to carry. The tightening mechanism 6 and the fixing rope 5 facilitate the fixing of the multi-section operating rod, improving the structural stability of the operating rod during use.
