Description

Technical Field

[0001] The invention belongs to the technical field of electric poles, and in particular relates to a casting-free pre-buried low-voltage electric pole. Background Art

[0002] In the power transmission and distribution system, utility poles are key infrastructure for supporting and transmitting electricity, and their stability and durability are crucial. Traditional utility pole installation methods mostly use the method of pouring concrete foundations. Although this method can provide better stability, it has a long construction period and requires a lot of manpower, material resources and water resources. Especially in some areas with complex geological conditions or sensitive environments, pouring concrete foundations may cause damage to the environment and is difficult to construct.

[0003] In addition, traditional utility poles may tilt or lose stability during long-term use due to external factors (such as wind load, impact, etc.). Once the utility pole tilts, it will not only affect the stability of power transmission, but also pose a safety hazard to the surrounding environment and pedestrians. Therefore, how to adjust and maintain the utility poles in a timely and effective manner to ensure their long-term stable operation has become an urgent problem to be solved.

[0004] At the same time, with the advancement of technology and the improvement of environmental awareness, people have begun to explore more environmentally friendly and efficient ways to install and maintain utility poles. For example, by using natural energy such as wind power to enhance the stability of utility poles, or by designing more intelligent adjustment mechanisms to cope with the influence of external factors.

[0005] However, current utility pole technology still has some shortcomings in these aspects. On the one hand, the existing cast-free pre-buried utility poles may not be comparable to traditional cast-in-place utility poles in terms of stability and grip; on the other hand, the existing utility pole adjustment mechanisms mostly rely on external equipment or manual intervention, lacking autonomy and intelligence.

[0006] In order to solve the above problems, a pre-buried low-voltage utility pole without casting is proposed, which can not only simplify the installation process and improve construction efficiency, but also has the functions of self-adjustment and enhanced stability to cope with the influence of external factors and ensure the stability and safety of power transmission.

[0033] Embodiment 1: In this embodiment, the work of pre-buried electric poles without pouring is realized by pre-buried ground anchors.

[0034] Specifically, it is reflected in the following steps: S 1: The staff first digs a pole pit where the electric pole needs to be buried, and rotates the installation block 302 with an electric device or a manual device. The installation block 302 drives the ground anchor 4 to rotate through the propulsion shaft 303 and drills the ground anchor 4 into the ground. When the bottom plate 308 contacts the ground, the rotation stops. It should be noted that the ground of the pole pit needs to be flat, and the number of each ground anchor 4 is adjusted according to the size of the electric pole 1 to form a circle and the distance between adjacent ground anchors 4; S 2 : Rotate the fixed block 301, make each of the flip blocks 305 face each other, flip each of the flip blocks 305 so that the flip blocks 305 are perpendicular to the fixed block 301, slide the extension block 307 into the inside of the flip block 305, and make each of the extension blocks 307 contact the center of the circle surrounded by the anchor 4; and bury the soil, and stop burying the soil when the soil is buried to the center of the fixed block 301; S 3 : Put the balance board 15 into the rod pit and contact the ground, and the position of the installation slot 1507 corresponds to the position of the fixed block 301. At this time, the balance board 15 is just between the two balance holes 3013 on the fixed block 301. Rotate the push-pull board 306 so that the push-pull board 306 is parallel to the flip block 305. The push-pull board 306 is connected to the balance board 15 through the rigid rope 14; Bury the soil until the soil covers the fixing block 301; S 4 : The base 2 is fixedly connected to the fixed block 301, and the main shaft 6 and the rotating cylinder 9 are placed into the interior of the utility pole 1 from above the utility pole 1, and the burial of the utility pole 1 is completed.

[0035] Embodiment 2: Based on embodiment 1, the utility pole also has the function of detecting the inclination of the main body and making fine adjustments, thereby solving the problem of the traditional utility pole being tilted due to external reasons.

[0036] Specifically, when the utility pole 1 is tilted due to external force, the fixed block 301 is tilted relative to the balance plate 15, and the rigid rope 14 pulls the push-pull plate 306 and causes the push-pull plate 306 to rotate, and the push-pull plate 306 drives the rotating shaft 309 to rotate, and the rotating shaft 309 drives the connecting rod 310 to rotate. While rotating, the connecting rod 310 slides on the push plate 311 and pushes the push plate 311. The balance bar 312 on the push plate 311 extends out from the inside of the fixed block 301, and thrust is generated by the balance bar 312 and the soil, so as to achieve the effect of verticalizing the utility pole 1, and the balance plate 15 is clamped by two adjacent balance bars 312, forcing the fixed block 301 to drive the utility pole 1 to adjust the angle.

[0037] Embodiment 3: Based on embodiment 1, the utility pole also has the function of converting the wind force and impact force that the utility pole 1 bears in daily life into the power of the propulsion pile 901, so as to achieve the purpose of making the utility pole 1 more stable.

[0038] Specifically, since the top of the utility pole 1 is at a high altitude and is more susceptible to strong winds, when wind blows into the utility pole 1 from the air inlet 101, the wind plate 801 is affected by the wind and drives the rotating shaft 8 to rotate slowly. The rotating shaft 8 drives the main shaft 6 to rotate through the rotating component 13. The main shaft 6 drives the rotating cylinder 9 to rotate and move downward through a threaded connection with the rotating cylinder 9.

[0039] When the utility pole 1 is hit, the buffer plate 201 buffers part of the force, and the buffer plate 201 moves toward the utility pole 1, and the buffer plate 201 drives the push rod 203 to move, and the push rod 203 drives the screw 12 to move, and the screw 12 drives the main shaft 6 to rotate through the threaded connection, thereby driving the rotating cylinder 9 to rotate and move downward.

[0040] The rotating cylinder 9 drives the propulsion pile 901 and the spiral plate 902 to rotate. The rotation of the spiral plate 902 assists the propulsion pile 901 to enter the soil. During the process of the propulsion pile 901 entering the soil, the discharged soil enters the interior of the propulsion pile 901 through the collecting port 903, thereby increasing the gravity of the propulsion pile 901 and making the steel frame of the electric pole 1 stable. When the propulsion pile 901 contacts the steel cable 1503 and pulls the steel cable 1503 downward, the steel cable 1503 drives the pulley 1504 and the gear 1505 to rotate, and the gear 1505 drives the rack 1506 to extend to the outside of the balance plate 15, thereby increasing the contact area between the device and the soil, thereby making the electric pole 1 more stable.

[0041] When the push pile 901 continues to move downward and contacts the extension block 307, under the squeezing of the push pile 901, the extension block 307 slides on the flip block 305, and the soil between the extension block 307 and the fixed block 301 is compacted during the sliding process, thereby making the utility pole 1 more stable.

[0043] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Although the present invention has been described in detail with reference to the above embodiments, a person skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some of the technical features can be replaced by equivalents, and these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
