Embodiment

[0035] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application. Embodiment

[0036] Please refer to Figures 1 to 9 The present application provides a technical solution: a power transmission tower anti-seismic device based on power transmission tower anti-seismic technology, comprising a working platform 1 and a swing assembly on the upper surface thereof, the bottom end of the swing assembly being fixedly connected with a load-bearing assembly, the top end of the swing assembly being fixedly connected with a base 5 configured to install the platform of the power transmission tower;

[0037] comprising a gravity center assembly, the gravity center assembly being located at the bottom end of the working platform 1 and fixedly connected with the lower surface of the working platform 1, the gravity center assembly being buried under the ground surface when installed;

[0038] comprising a support assembly, the support assembly being located at the top end of the working platform 1 and fixedly connected with the upper surface of the working platform 1;

[0039] comprising an electric energy conversion module, a calibration module and an electromagnetic induction module, the electric energy conversion module and the calibration module being located on the upper surface of the working platform 1 and fixedly connected with the working platform 1, the electromagnetic induction module being located on the lower surface of the working platform 1 and fixedly connected with the working platform 1;

[0040] The electric energy conversion module is electrically connected with the load-bearing assembly, the gravity center assembly and the support assembly and is configured to store and release energy by kinetic energy in the electric energy conversion assembly;

[0041] The electromagnetic induction module is electrically connected with the gravity center assembly and is configured to energize the lower surface of the working platform 1 to form a strong magnetic field after meeting the conditions.

[0042] The calibration module is configured with a sensor and electrically connected with the electric energy conversion module, for monitoring external changes and sending signals to the electric energy conversion module.

[0043] When the earthquake occurs, the body wave appears first, in which the propagation speed of the longitudinal wave P wave is faster than that of the transverse wave S wave, and the surface wave is a secondary wave generated by the encounter of the longitudinal wave and the transverse wave on the ground, so it is slightly later than the body wave, and after the surface wave, a series of seismic tail waves follow.

[0044] First, the first wave arriving at a certain place from the seismic source is the "push and pull" P wave. They generally exit the ground at a steep angle, thus causing vertical ground motion, and through the load-bearing assembly and the supporting assembly, the impact of the P wave on the power transmission tower can be effectively absorbed and converted into the elastic potential energy of the spring, which is further converted into electric energy and stored in the electric energy conversion module later.

[0045] Because the propagation speed of the S wave is about half of that of the P wave, the relatively strong S wave arrives slightly later, and the earthquake mainly causes the power transmission tower to sway laterally through the action of the S wave, at which time a part of the impact of the S wave on the power transmission tower is absorbed by the gravity center assembly, and the swing assembly further weakens the swinging degree of the power transmission tower.

[0046] After the earthquake ends, the calibration module sends a signal to the electric energy conversion module, so that the overall device returns to the initial state. Embodiment

[0047] The swing assembly comprises a cross shaft 2, the outer wall of the longer section of the cross shaft 2 is sleeved with a cross frame 21 at both ends in the axial direction, the top end of the cross frame 21 is fixedly connected with the base 5, the bottom of the two ends in the shorter axial direction of the cross shaft 2 is sleeved with a connecting piece 22, and the bottom end of the connecting piece 22 is fixedly connected with the load-bearing assembly.

[0048] The load-bearing assembly comprises an upper load-bearing shaft 23, the outer wall of the bottom end of the upper load-bearing shaft 23 is sleeved with a lower load-bearing shaft 24, and the bottom end of the upper load-bearing shaft 23 is elastically connected with the load-bearing spring 25 in the inner wall of the lower load-bearing shaft 24.

[0049] When the earthquake occurs, the working platform 1 starts to do the vertical reciprocating linear motion under the action of P wave, since the lower bearing shaft 24 is fixedly connected with the working platform 1, that is, the motion state of the lower bearing shaft 24 is the same as that of the working platform 1, and the upper bearing shaft 23 is drivingly connected with the lower bearing shaft 24 through the bearing spring 25, therefore, along with the motion of the lower bearing shaft 24, most of the kinetic energy is converted into the elastic potential energy of the bearing spring 25, since the bearing spring 25 is electrically connected with the electric energy conversion module, therefore, this part of energy is finally stored in the electric energy conversion module in the form of electric energy, and since most of the energy is converted, the force received by the upper bearing shaft 23 is greatly weakened, that is, the motion amplitude of the upper bearing shaft 23 is weakened to a certain extent compared with that of the lower bearing shaft 24, thereby effectively reducing the impact of P wave on the power transmission tower. Embodiment

[0050] The gravity center assembly comprises a protective shell 3 fixedly connected with the lower surface of the working platform 1, and a gravity center ball 31 placed in the interior of the protective shell 3, and a limiting spring 32 elastically connected between the protective shell 3 and the gravity center ball 31.

[0051] The support assembly comprises a connecting column 4, the bottom end of the connecting column 4 is fixedly connected with the gravity center ball 31, the bottom end of the connecting column 4 penetrates through and is movably connected with the working platform 1, one side of the connecting column 4 is drivingly connected with a driving shaft 41 through a pin shaft, the outer wall of the end of the driving shaft 41 axially away from the connecting column 4 is sleeved with a transmission shaft 42, the driving shaft 41 is limitingly movably connected with the transmission shaft 42, the end of the transmission shaft 42 axially away from the driving shaft 41 is drivingly connected with a fixed column 44 through a pin shaft, the bottom end of the fixed column 44 is fixedly connected with the upper surface of the working platform 1, and the transmission shaft 42 and a reset spring 43 are externally sleeved with the reset spring 43.

[0052] The distance between the top end of the gravity center ball 31 and the bottom end of the working platform 1 is, and the distance between the top end of the connecting column 4 and the bottom end of the base 5 is , wherein .

[0053] After the earthquake occurs for a period of time, the S wave reaches the ground and starts to impact the power transmission tower, since the gravity center assembly is buried in the ground, the S wave first impacts the gravity center assembly, thereby causing the protective shell 3 to start to do the horizontal reciprocating motion, and the protective shell 3 is drivingly connected with the gravity center ball 31 through the limiting spring 32, along with the motion of the protective shell 3, most of the kinetic energy is converted into the elastic potential energy of the limiting spring 32, since the limiting spring 32 is electrically connected with the electric energy conversion module, therefore, this part of energy is stored in the electric energy conversion module in the form of electric energy, thereby weakening the impact degree of the S wave on the power transmission tower.

[0054] When the S wave impacts the working platform 1, the working platform 1 is fixedly connected with the load-bearing assembly, i.e., the upper load-bearing shaft 23 starts to swing, the connecting piece 22 is fixedly connected with the upper load-bearing shaft 23, the cross shaft 2 is rotatably connected with the connecting piece 22, the movement state of the upper load-bearing shaft 23 makes a limited circular arc movement around the short shaft of the cross frame 21 under the action of the cross shaft 2, the power transmission tower is installed at the top end of the base 5, the base 5 is fixedly connected with the cross frame 21, and the cross frame 21 is rotatably connected with the cross shaft 2, so that the base 5 is greatly reduced under the action of the upper load-bearing shaft 23, thereby effectively reducing the impact of the S wave on the power transmission tower.

[0055] At the same time, when the limiting spring 32 is deformed, the working conditions of the electromagnetic induction module are met, the lower surface of the working platform 1 starts to be electrified to form a strong magnetic field, and the gravity center ball 31 is attracted to the bottom end of the working platform 1 under the action of the magnetic force, thereby effectively reducing the gravity center of the whole device, so that the gravity center height of the power transmission tower does not exceed the geometric center height.

[0056] The impact of the P wave on the power transmission tower also causes the gravity center ball 31 to reciprocate in the vertical direction, the gravity center ball 31 is fixedly connected with the connecting column 4, i.e., the movement state of the connecting column 4 is the same as that of the gravity center ball 31, the connecting column 4 is drivingly connected with the fixed column 44 through the reset spring 43, so that part of the energy is converted into the elastic potential energy of the reset spring 43, and further stored in the electric energy conversion module in the form of electric energy, thereby further weakening the impact of the P wave on the power transmission tower.

[0057] After the earthquake ends, the calibration module starts to work, sends a signal to the electric energy conversion module by monitoring the changes of the external environment, the electric energy conversion module outputs electric energy to each component so as to restore the initial state, at this time, the electromagnetic induction module stops working, and the gravity center ball 31 starts to fall under the action of gravity until it contacts the inner wall of the protective shell 3.

[0058] The electric energy conversion module is internally provided with a generator rotor and a mechanical device for converting the deformation movement of the spring. The deformation movement of the spring can drive the rotor of the generator to rotate through some mechanical devices. When the rotor rotates, it will cut the magnetic lines of force in the magnetic field, thereby generating an electromotive force in the coil of the generator. The electromotive force can drive electric current to flow through the external circuit, thereby generating electric energy.

[0059] In the scheme, the kinetic energy of the axial relative movement between the upper load-bearing shaft 23 and the lower load-bearing shaft 24 can also be converted into electric energy, so as to fully utilize the collected kinetic energy and realize more efficient electric energy conversion.

[0060] The electromagnetic induction module and the interior of the working platform 1 are both configured with high-tap number threaded pipes. When the current passes through the threaded pipes, each tap of the solenoid will generate a magnetic field. The magnetic fields generated by the high-tap number are superimposed on each other, thereby generating a strong magnetic force to attract the barycentric ball 31.

[0061] While embodiments of the application have been shown and described, it is to be understood that the embodiments described are only by way of example and that modifications, changes, substitutions and alterations can be made thereto without departing from the spirit and scope of the application as defined by the appended claims and their equivalents.
