Description

Technical Field

[0001] The utility model relates to the technical field of electric power piles, in particular to an anti-overturning directly buried electric power pile. Background Art

[0002] In recent years, extreme weather conditions have occurred frequently around the world, especially natural disasters such as typhoons, which have had a serious impact on power infrastructure. Typhoons landing can cause serious accidents such as tilted poles, collapsed poles, broken poles, and broken lines in distribution lines with poor wind resistance, which poses a great threat to the safe operation of distribution networks in coastal areas.

[0003] Currently, existing power piles usually use chassis, chucks and other structures to avoid overturning. These chassis and chucks usually adopt a split splicing design and are reinforced with reinforced concrete or plain concrete. Although this method is strong, it is good at withstanding the downward pressure transmitted by the pole, but poor at withstanding the horizontal force. When the pole is tilted, it is impossible to monitor the working status of the foundation. In addition, when the power pile is buried underground, the conventional direct burial method is difficult to judge its stable state. The uneven force on the chassis causes tilting, leaving a balance risk. Once an accident occurs later, it will lead to serious tilting or even falling accidents. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides an anti-overturning direct-buried power pile.

[0005] The technical solution of the utility model is: an anti-overturning direct-buried power pile, comprising a power pile, a fixed base arranged at the bottom of the power pile, and a steel mesh layer laid around the fixed base; a cavity is arranged inside the fixed base, a gear disc and a motor are arranged at the bottom of the fixed base, and the central shaft of the gear disc is fixedly connected to the output end of the motor;

[0006] A plurality of rotating rods are circumferentially and rotatably arranged on the side wall of the fixed base, a reinforcement ring plate is arranged on the top of the fixed base, and the plurality of rotating rods are rotatably connected to the reinforcement ring plate, and one end of the rotating rod that passes through the side wall of the fixed base is provided with a gear meshing with a gear plate; a screw is arranged on the other end of the rotating rod, and a threaded tube is sleeved on the outside of the screw and threadedly connected, a limiting plate is arranged on the side wall of the fixed base, and a groove is arranged on the outer wall of the threaded tube; a protrusion that is slidably engaged with the groove is arranged on the surface of the limiting plate.

[0007] Description: The construction of anti-overturning direct-buried power pile technology includes on-site excavation of foundation pits, burying fixed bases, laying steel mesh layers, and pouring cement mortar. The use of this design not only simplifies the construction process but also can detect the buried stability of the power piles through sensors, which is convenient for later maintenance.

[0008] Furthermore, the steel mesh layer is formed by arranging and fixing a plurality of transversely arranged steel bars and a plurality of longitudinally arranged steel bars; the cross-sectional diameter of the steel bars is 5 to 15 cm, the length is 3 to 5 m, and the arrangement interval between two adjacent steel bars is 0.5 to 1 m; and an inclination sensor and a communication module are arranged on the top of the power pile.

[0009] Description: The steel mesh layer is composed of transverse steel bars and longitudinal steel bars, which can be fixed together by welding or other connection methods to form a stable mesh structure. Such a structure can effectively disperse the force and increase the lateral constraint of the soil layer around the power pile, thereby reducing the risk of overturning and improving the stability and safety of the power pile.

[0010] Furthermore, an electric-controlled drill bit is provided at the end of the threaded pipe; and a stop assembly is also provided on the fixed base.

[0011] Description: The electric drill bit can be used to break the hard soil and rocks encountered by the threaded pipe during the extension path, eliminating path obstacles; the toothed disc can be locked through the stop assembly to prevent the gear from shaking.

[0012] Furthermore, the stop assembly includes a stop screw that is threadedly connected and penetrates through the top of the fixed base, and a thread groove that is arranged on the gear disk and corresponds to the stop screw.

[0013] Note: When the toothed disc rotates to the longest position where the threaded tube extends, the thread groove corresponds to the longitudinal position of the stop screw. By rotating the stop screw into the thread groove to fix the toothed disc, the natural rotation of the toothed disc can be effectively prevented after the motor is turned off.

[0014] Furthermore, the stop assembly includes a limit rod that passes through and is slidably arranged on the top of the fixed base, a fixing hoop that is arranged on the top of the fixed base and is used to clamp and fix the limit rod, and a through groove that is arranged on the toothed disk and is slidably clamped with the limit rod.

[0015] Description: Use the limit rod and the fixing hoop to limit the toothed disc. When the toothed disc rotates to the longest position of the threaded tube, the through slot corresponds to the longitudinal position of the limit rod. Insert the limit rod into the through slot, and fasten the fixing hoop to prevent the limit rod from sliding longitudinally. This can fix the toothed disc and prevent the toothed disc from rotating naturally after the motor is turned off.

[0016] Furthermore, a filling port is provided on the fixed base, a filling bag is provided on the top fixed sleeve outside the threaded tube, and the filling port is connected with the filling bag through the internal guide groove of the fixed base; an electric control valve is provided at the connection point;

[0017] A one-way valve groove for exhausting air is arranged on the perfusion bag, the outer top of the threaded tube is fixedly connected with the perfusion bag, and an opening communicating with the perfusion bag is arranged on the side wall of the top of the threaded tube.

[0018] Description: After the fixed base is buried, the threaded tube is stretched and the balance state of the power pile is detected by the inclination sensor. If the buried power pile is tilted, pour a proper amount of concrete, cement, mortar and other reinforcement materials into the pouring port, open the corresponding electric control valve that is symmetrical in this direction, and let the reinforcement material flow into the pouring bag. Let it stand and solidify. The pouring bag after adding materials has an increased mass, so that the threaded tube at this position squeezes the base soil and sinks. The filling amount of each pouring bag can be controlled to further adjust the balance of the power pile.

[0019] The beneficial effects of the utility model are as follows: the utility model embeds the fixed base, utilizes the steel mesh layer to strengthen the stability of the fixed base, the motor rotates the gear plate, and the threaded pipe moves and extends laterally under the action of the screw and the limit plate, squeezing the foundation soil on both sides, and laterally strengthening the anti-overturning ability of the power pile; the inclination sensor and the communication module are used to monitor the stability of the power pile, and the power pile is repaired in time when it tilts to avoid accidents; the balanced embedding of the power pile is controlled according to the foundation characteristics, and the stability and maintenance efficiency of the power pile are improved.
