[0002] As a key component of the power transmission system, the structural stability and safety of the transmission tower foundation are crucial to the normal operation of the power system. Lightning strikes are one of the important natural disasters that cause damage to the transmission tower foundation. Lightning strikes not only damage the transmission tower and the foundation itself, but also threaten the stability of the transmission tower foundation, thereby affecting the stability and safety of the entire power transmission network. In recent years, with the frequent occurrence of extreme weather events, the number of incidents of transmission tower foundations being damaged by lightning strikes has increased, posing a huge challenge to the operation of the power system.

[0003] Once the transmission tower foundation structure is damaged by lightning, the maintenance and reinforcement methods often require a lot of manpower and material resources, and usually require power outages, affecting the continuity of power supply. The traditional reinforcement method is to expand the foundation method. However, this method is usually carried out after the accident, and often cannot respond to sudden lightning disasters in time, especially in remote areas, where it cannot be quickly reinforced, resulting in reduced stability of the transmission tower foundation structure or even instability and damage.

[0005] To achieve the above objectives, the technical solution of the present invention is: an automatic reinforcement device for a transmission tower foundation damaged after a lightning strike, comprising a seepage pipe, a liquid storage box, reinforcement ribs, and a push rod, wherein the seepage pipe is vertically inserted into the interior of the transmission tower foundation, a plurality of seepage holes are provided on the side of the seepage pipe, the liquid storage box is installed in the seepage pipe, the liquid storage box is filled with adhesive, a plurality of liquid flow holes are provided on the side surface of the liquid storage box near the top, the push rod is vertically slidably connected to the liquid storage box, the lower end of the push rod is connected to a baffle, the baffle abuts against the inner side wall of the liquid storage box, the upper end of the push rod passes through the liquid storage box, the seepage pipe, and the transmission tower foundation and is connected to the end of the reinforcement rib, and the reinforcement rib is annularly wound around the outer side surface of the transmission tower foundation.

[0006] The outer side of the seepage pipe is horizontally connected to an expansion tube, one end of the expansion tube is connected to a hollow spherical tube, an ultrasonic vibration generator is installed in the hollow spherical tube, a spherical groove is opened on the side wall of the hollow spherical tube, the hollow spherical tube is connected to one end of the expansion tube, the ultrasonic vibration generator is connected to a capacitor through a wire, the capacitor is installed on the top of the transmission tower foundation, and the capacitor is used to store electrical energy generated by lightning strikes.

[0007] The side wall of the expansion tube is provided with a plurality of liquid seepage holes, and the outer side wall of the hollow ball tube is provided with a plurality of liquid seepage holes.

[0008] The upper end of the push rod is connected to a displacement sensor, which is connected to an alarm through a wire. The alarm is installed on the top of the transmission tower foundation. The displacement sensor is used to pull the wire when it moves upward to a threshold value, so that the alarm sends an alarm signal.

[0009] The upper end of the liquid storage box is open, and a sealing cover is connected to the open end of the liquid storage box. The sealing cover is sleeved on the outer circumferential surface of the push rod, and the sealing cover abuts against the inner wall of the seepage tube. A stretching assembly is connected to the upper side of the sealing cover, and one end of the stretching assembly is connected to the push rod. The stretching assembly is used to drive the sealing cover to move downward when the push rod moves upward.

[0010] The stretching assembly includes a first connecting rod, a second connecting rod and a traction rope, one end of the first connecting rod is hinged to the upper side of the sealing cover, one end of the second connecting rod is hinged to the other end of the first connecting rod, the other end of the second connecting rod is hinged to the top wall of the seepage tube, one end of the traction rope is connected to the hinge of the first and second connecting rods, and the other end of the traction rope is connected to the push rod.

[0011] The reinforcing bars are BFRP bars.

[0012] The adhesive is epoxy resin glue.

[0013] A method for using a device for automatically reinforcing a foundation of a power transmission tower damaged after a lightning strike, the method comprising the following steps:

[0014] Step 1: Install the liquid storage box in the seepage pipe, place the seepage pipe at the center of the point to be poured, and then pour the transmission tower foundation concrete;

[0015] Step 2: Wrap the reinforcement bar around the outer side of the transmission tower foundation, and fix the extended reinforcement bar to the top of the push rod;

[0016] Step 3: When lightning strikes the transmission tower foundation, several cracks will be generated inside the transmission tower foundation, which increases the porosity of the transmission tower foundation, thereby causing the volume of the transmission tower foundation to expand laterally. During the lateral expansion of the transmission tower foundation, the reinforcement bars pull the push rod upward to allow the adhesive in the liquid storage box to flow into the seepage pipe through the flow holes, and the adhesive further penetrates into the cracks inside the transmission tower foundation through the seepage pipe for reinforcement.

[0017] When lightning strikes the foundation of a transmission tower, part of the lightning energy is stored in the capacitor. The electrical energy is transmitted through the wire to start the ultrasonic vibration generator.

[0019] 1. In the automatic reinforcement device for the foundation of a power transmission tower damaged after a lightning strike and the use method thereof, the reinforcement ribs are wound around the outer side of the power transmission tower foundation and the ends are fixed on the push rod. When the volume of the power transmission tower foundation expands after a lightning strike, the push rod is pulled upward to discharge the adhesive, so that the adhesive can penetrate from the inside of the power transmission tower foundation into the cracks generated after the lightning strike, achieving the effect of automatic reinforcement and reducing the input of manpower and material resources in the reinforcement stage. Therefore, the present invention has a high degree of automation and a high reinforcement efficiency.

[0020] 2. In the automatic reinforcement device for the foundation of a power transmission tower damaged after a lightning strike and the use method thereof, an ultrasonic vibration generator and a capacitor are provided, and the capacitor is used to store the electric energy generated by the lightning strike to supply the ultrasonic vibration generator. Since the hollow spherical tube connected to the end of the expansion tube is a hollow structure, the ultrasonic vibration generator is placed inside the spherical structure and contacts the side wall of the spherical structure, which can generate vibration to make several closed cracks inside the foundation of the power transmission tower penetrate, and prevent the adhesive from damaging the ultrasonic vibration generator, so that the adhesive can penetrate into the through channel, better reinforce the cracks, and improve the overall stability; the seepage holes provided on the side wall of the expansion tube can increase the infiltration area, and the reinforcement effect is better than that of infiltration from the outer surface. At the same time, setting it inside can avoid weathering erosion and increase its service life. Therefore, the present invention has good reinforcement effect and long service life.

[0021] 3. In the automatic reinforcement device for the foundation of a power transmission tower damaged after a lightning strike and its use method of the present invention, a displacement sensor and an alarm are set, and when the displacement sensor reaches a certain threshold, an early warning signal is released to remind the staff to perform fluid replenishment and evaluation operations; during the reinforcement operation, the push rod will drive the traction rope during the upward movement, and the traction rope will pull the first connecting rod and the second connecting rod, so that the angle between the two connecting rods becomes larger, thereby pushing the sealing cover to move downward; the downward movement of the sealing cover will squeeze the adhesive in the seepage tube to apply confining pressure to the inner wall of the power transmission tower foundation, and work together with the reinforcement ribs wrapped around the outside of the power transmission tower foundation to put the power transmission tower foundation in a bidirectional force state, thereby improving the bearing capacity of the power transmission tower foundation. Therefore, the present invention has a high degree of automation, high reliability, and good reinforcement quality. BRIEF DESCRIPTION OF THE DRAWINGS
