[0002] In the field of power transmission, cement poles have become the core supporting components for erecting power lines due to their advantages such as low cost, high durability, and good corrosion resistance. Whether it is the orderly laying of urban power grids or the power coverage of remote rural areas, cement poles bear the heavy responsibility of fixing and supporting equipment such as power lines, cables, and transformers, ensuring that electricity can be transmitted stably and safely to thousands of households, playing an irreplaceable role in the construction of power infrastructure.

[0003] Traditional cement power poles are produced using a prefabricated method. They are cast in the factory after being pre-set to a fixed height, and then transported to the construction site. Installation is carried out through a process of excavating a foundation pit, hoisting the pole, and backfilling and compacting. They rely on their own weight and the fixing effect of the foundation to maintain their upright position and provide support for power lines. However, due to the fixed height working mode, traditional cement poles cannot adapt to the dynamic adjustment requirements of line height during power system upgrades and renovations. They lack flexibility and adaptability, which leads to obstacles in power transmission. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a multi-layer reinforced prestressed cement pole for power transmission, which aims to improve the problem that traditional cement poles, due to their fixed height working mode, cannot adapt to the dynamic adjustment requirements of line height during power system upgrades and renovations, thus hindering power transmission.

Detailed Implementation

[0025] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a multi-layer reinforced prestressed cement pole, comprising a main pole 1, a plurality of support shells 2 fixedly connected to the top of the main pole 1, an outer shell 3 fixedly connected to the top of the support shells 2, a motor 4 fixedly connected to the inner wall of the outer shell 3, a lead screw 5 fixedly connected to the output end of the motor 4, a slider 7 threadedly connected to the outer wall of the lead screw 5, a plurality of sliding cables 8 installed at the top of the slider 7, a collar 9 slidably connected to the outer wall of the main pole 1, a plurality of mounting plates 10 fixedly connected to the outer wall of the collar 9, a plurality of mounting rings 11 fixedly connected to the top of the mounting plates 10, an auxiliary stabilizing component provided at the bottom of the main pole 1, a support plate 6 fixedly connected to the inner wall of the main pole 1, and the lead screw 5 rotatably connected to the inner wall of the support plate 6.

[0027] Specifically, the main pole 1 and the outer casing 3 are connected by multiple support shells 2. The outer casing 3 provides support for the installation of the motor 4. The slider 7 and the collar 9 are connected by a sliding cable 8. The slider 7 drives the sliding cable 8 to rise and fall. The lead screw 5 drives the slider 7 to rise and fall. The outer casing 3 then drives the lead screw 5 to rise and fall, thus realizing the effect of adjusting the height of the collar 9 using the outer casing 3. The mounting plate 10 and mounting ring 11 connected to the collar 9 serve as the mounting carrier for the wires, realizing the basic function of the power cement pole.

[0028] Reference Figure 1 and Figure 7 The auxiliary stabilizing components include a base 15, which is fixedly connected to the bottom end of the main rod 1. Multiple abutment rods 16 are threadedly connected to the outer wall of the base 15, and multiple abutment plates 18 are fixedly connected to the outer wall of the base 15. A support ring 17 is fixedly connected to the outer wall of the main rod 1, and a support rod 19 is fixedly connected to the opposite side of the support ring 17 and the abutment plates 18. Multiple counterweight balls 21 are slidably connected to the inner wall of the base 15, and a groove 20 is opened at the bottom end of the main rod 1. The counterweight balls 21 are slidably connected to the inner wall of the groove 20.

[0029] Specifically, the base 15 is securely installed by multiple abutment rods 16 threaded onto it. The base 15 is also fitted over the bottom of the main rod 1 to prevent it from directly contacting the ground and being corroded. Multiple support rods 19 are connected between the base 15 and the support ring 17 installed on the main rod 1 to provide auxiliary support for the entire main rod 1. If the main rod 1 is hit or vibrates due to an earthquake, multiple counterweight balls 21 sliding in the groove 20 at the bottom of the base 15 will slide in real time to the opposite direction of the swaying due to inertia, thereby counteracting the overturning moment and ensuring the stability of the main rod 1.

[0030] Reference Figure 1 and Figure 2 A solar panel 22 is installed on the top of the outer casing 3, and a battery 23 is installed on the inner wall of the solar panel 22. The motor 4 and the battery 23 are electrically connected.

[0031] Specifically, solar energy is collected by solar panel 22 and stored in battery 23 to provide power to motor 4, which drives the height adjustment component and can also drive the operation of other electronic devices subsequently installed on the main pole 1.

[0032] Reference Figure 6 The inner wall of the main rod 1 is evenly provided with multiple steel bars 14.

[0033] Specifically, the main rod 1 is supported by multiple layers of steel bars 14, and the steel bars 14 are prestressed to ensure the strength and toughness of the main rod 1.

[0034] Reference Figure 3 , Figure 4 and Figure 5 The inner wall of the support shell 2 is rotatably connected to multiple pulleys 12, and the cable 8 is slidably connected to the outer wall of the pulleys 12. The other end of the cable 8 is installed on the top of the collar 9.

[0035] Specifically, during the lifting and sliding process, the zipline 8 is always limited by the pulley 12, and the pulley 12 is used to change the direction of the zipline 8, thereby driving the collar 9 to lift and adjust its height.

[0036] Reference Figure 1 and Figure 5 Multiple limiting rings 13 are fixedly connected to the outer wall of the main rod 1. The sliding cable 8 is slidably connected to the inner wall of the limiting rings 13. Multiple limiting grooves are opened on the outer wall of the main rod 1. The collar 9 is slidably connected to the inner wall of the limiting groove.

[0037] Specifically, multiple limiting rings 13 limit the sliding of the cable 8 to prevent it from shifting or rotating during the sliding process, which would affect the installation stability of the wire. At the same time, the limiting groove limits the lifting and lowering of the collar 9 to ensure that it remains straight and does not rotate during the lifting and lowering process.

[0038] Working principle: When using this electric cement pole, the main pole 1 is placed on the ground through the base 15, and the abutment plate 18 is rotated to insert it into the ground for auxiliary fixation. The abutment rod 16 will also assist in supporting and fixing the main pole 1. When an earthquake or vibration occurs, the counterweight ball 21 will slide around the groove 20 in real time to offset the overturning moment, thereby reducing the vibration of the main pole 1 and protecting the stability of the top wire.

[0039] After the cement pole is installed, if the actual height does not match the fixed installation height of the wire due to terrain differences, the motor 4 needs to be started to drive the lead screw 5 to rotate. This causes the slider 7 connected to the thread on the lead screw 5 to slide up and down along the lead screw 5. This causes the slider 7 to slide in the opposite vertical direction through the sliding cable 8 and drive the collar 9 connected to the other end of the sliding cable 8 to adjust the height of the mounting plate 10 and the mounting ring 11 on the collar 9, thereby meeting the installation height requirements of the wire.

[0040] In normal operation, the electricity collected by the solar panel 22 is stored in the battery 23 to drive the motor 4.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
