Description

Technical Field

[0002] Power transmission is a crucial component of the overall functioning of power systems. Power plants and load centers are typically located in different regions. Power plants are built in locations with suitable primary energy resources such as hydropower and coal. Transmission can then deliver electricity to load centers located far from the power plants, enabling the development and utilization of electricity beyond geographical constraints. Compared to other energy transmission methods, transmission offers advantages such as low losses, high efficiency, flexibility, ease of regulation and control, and reduced environmental pollution.

[0003] Power transmission requires the use of transmission cables. In order to prevent the transmission cables from hanging to the ground and obstructing traffic, they are generally supported by poles and other supports. When the supports are damaged by external factors, workers are required to repair and replace them in time to ensure the safety of power transmission. When replacing the supports, in order to ensure the normal power transmission, workers generally use temporary stringing devices to hold up the transmission cables. When using common temporary stringing devices, because their bottom support surface is small, in order to ensure their stability, their bottom is generally buried in the soil layer. If the burial depth is shallow, their stability is poor. If the burial depth is deep, it will increase the difficulty of use and the amount of engineering work, which is not conducive to their convenient use. Utility Model Content

[0028] By adjusting the positions of the two studs 12 on the same carrier 8, the expansion plate 10 can be limited by one of the studs 12 when rotating around the pin to a horizontal state or a vertical state. After the multiple expansion plates 10 are unfolded in a circle, the multiple nails 11 on the expansion plates 10 can be inserted into the soil layer, which helps to fix the expansion plates 10 while allowing the multiple expansion plates 10 to cooperate with the four rollers 16 to have a greater degree of contact with the ground.

[0034] Working principle of this utility model:

[0035] The device is moved to a designated position using four rollers 16. A wrench is then removed and used to tighten the first bolt 17, causing the first bolt 17 to push the rack 18 to move. The rack 18 meshes with the first gear 4, driving the first gear 4 to rotate. This causes the first gear 4 to pull the first pillar 3 and the second gear 5 to rotate. The second gear 5 meshes with the plurality of second pillars 6, driving the plurality of second pillars 6 to rotate simultaneously. The second pillars 6, with the help of the third gear 7, pull the carrier 8 to rotate. The carrier 8 pulls the expansion plate 10 to rotate 180°, causing the nails 11 on the expansion plate 10 to flip outward.

[0036] The upper stud 12 is twisted to disengage the slot 14. At this time, the expansion board 10 is no longer restricted by the upper stud 12. The expansion board 10 is rotated so that the nail 11 on the expansion board 10 is inserted into the ground layer. The expansion board 10 is hit with a hammer until the expansion board 10 rotates to a horizontal state. At this time, the nail 11 is embedded in the soil layer, which can ensure the stability of the connection between the expansion board 10 and the ground. The lower stud 12 is twisted so that the lower stud 12 is inserted into the slot 14. In this way, the lower stud 12 cooperates with the carrier 8 to lock the position of the expansion board 10 again. Multiple expansion boards 10 are deployed in a circular shape. With the help of four rollers 16, they can have a wide range of contact with the ground and are not easy to tip over or move.

[0037] The transmission cable is placed inside the two U-shaped plates 22, and the transmission cable is lifted by multiple auxiliary rollers 23. The cover plate 24 is rotated to cover the top of the U-shaped plate 22, and the U-shaped plate 22 and the cover plate 24 are locked with a lock so that the transmission cable cannot be separated from the U-shaped plate 22. The rocker 30 is rotated so that the rocker 30 pulls the worm 29 to rotate, and the worm 29 drives the turbine 28 to rotate, so that the turbine 28 pulls the lead screw 26 to rotate, and the lead screw 26 pulls the support plate 27 and the second square tube 20 thereon upward in a lead screw transmission manner, so that the transmission cable is lifted. After the transmission cable is lifted to a suitable height, the rotation of the rocker 30 is stopped, and the two second bolts 21 are tightened with a wrench to lock the first square tube 19 and the second square tube 20, thereby ensuring the stability of the height of the transmission cable, so that the transmission cable can ensure normal power transmission without affecting the daily activities of people around it.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
