Description

Technical Field

[0001] The invention belongs to the technical field of tee pipes, and in particular relates to a tee pipe with an outer wall repairing device. Background Art

[0002] As the name suggests, a tee pipe has three openings, that is, one inlet and two outlets; or two inlets and one outlet. It can be T-shaped or Y-shaped, with equal-diameter or reducing-diameter openings. It is used at the confluence of three identical or different pipelines. Its main function is to change the direction of the fluid. It can be used for water pipelines, oil pipelines and various liquid chemical material pipelines. It is mainly used in engineering fields such as medicine, water conservancy (water-saving irrigation, water supply and drainage), energy (petroleum, natural gas, nuclear industry), and construction. However, during use, the outer wall of the tee pipe is prone to cracks due to rust or corrosion. If it is not repaired in time, it is easy to leak. Summary of the Invention

[0003] The purpose of the present invention is to provide a three-way pipe with an outer wall repair device to solve the above-mentioned technical problems.

[0004] To achieve the above-mentioned purpose, the specific technical solution of a three-way pipe with an outer wall repair device of the present invention is as follows: A tee pipe with an outer wall repair device includes a tee pipe, a moving component and a detection component. The moving component includes a bracket, a driving roller, a driving roller motor, a rotating bracket, and a rotating bracket motor. The bracket is rotatably mounted with a rotating bracket, the rotating bracket is connected to the output shaft of the rotating bracket motor, the rotating bracket motor is mounted on the bracket, the rotating bracket is rotatably mounted with a driving roller, the driving roller is mounted on the output shaft of the driving roller motor, the driving roller motor is mounted on the rotating bracket, the bracket is mounted with a repair component for repairing the outer wall of the tee pipe, and the bracket is mounted with a detection component for detecting gaps in the tee pipe.

[0005] Furthermore, the outer wall repair component includes a welding gun, a solder bin, and a solder pump. The solder bin is fixedly installed on the bracket, the solder bin is installed with a solder pump for pumping out solder, and the welding gun is installed on the melting furnace.

[0006] Furthermore, the detection component includes an ultrasonic transmitter, an ultrasonic receiver, a pulse generator, a signal processor and a displacement sensor. The ultrasonic transmitter is used to emit high-frequency ultrasonic waves, and the ultrasonic receiver is used to contact the sound wave signal reflected back from the tee pipe and transmit the sound wave signal to the signal processor. The signal processor analyzes the echo time difference, echo amplitude and echo waveform pattern to determine the form of the defect. The displacement sensor transmits the position information of the moving component in the tee pipe to the signal processor. When the signal processor determines that the detected defect is a gap, the gap position is determined by the displacement sensor, and the outer wall repair component is driven to realize the welding repair of the gap on the outer wall of the tee pipe.

[0007] Furthermore, the signal processor includes a communication module, a data storage module, a power supply module and a CPU module. The ultrasonic receiver communicates with the communication module in a one-way manner, the communication module communicates with the CPU module in a two-way manner, the CPU module communicates with the data storage module in a one-way manner, the power supply module supplies power to the signal processor, the CPU module communicates with the driving roller motor, the rotating bracket motor, the solder pump and the welding gun in a one-way manner through the communication module, and the CPU module communicates with the displacement sensor in a one-way manner through the communication module.

[0008] Furthermore, the frequency range of the ultrasonic transmitter is 0.5–22 MHz‌.

[0009] Furthermore, the pulse generator has an emission voltage of 100–450 V and a pulse width of 30–2500 ns.

[0010] Furthermore, the dynamic range of the signal processor is ‌≥32dB‌, and the gain adjustment of the signal processor is ‌0–110dB.

[0011] Furthermore, a coupling agent is provided between the outer wall of the three-way pipe and the ultrasonic transmitter to ensure the conduction of sound waves.

[0012] Furthermore, the coupling agent is engine oil.

[0013] Furthermore, the welding repair method for the outer wall gap of the tee pipe comprises the following steps: S1: First, an ultrasonic transmitter transmits ultrasonic waves to the outer wall of a tee without gaps, and an ultrasonic receiver receives the echo. The signal processor records the echo time difference, echo amplitude, and echo waveform of the echo, and defines the echo as a standard waveform. S2: Take multiple samples at different positions of the tee pipe to perform standard waveform calibration; S3: The CPU module of the signal processor sends a signal to the driving roller motor and starts the driving roller motor. The driving roller motor drives the driving roller to rotate, and drives the entire moving component together with the detection component and the outer wall repair component to move simultaneously; S4: When the CPU module of the signal processor determines that there is a defect by analyzing the echo time difference, echo amplitude and echo waveform pattern, it obtains the current position information through the displacement sensor and stores the current position information in the data storage module of the signal processor; S5: The CPU module of the signal processor analyzes the defect form. When the CPU module of the signal processor determines that the defect form is a gap, the CPU module of the signal processor starts the rotating bracket motor, so that the rotating bracket motor drives the rotating bracket to rotate in a direction parallel to the cross section of the tee pipe, so that the moving component rotates circumferentially along the outer wall of the tee pipe, and the CPU module of the signal processor starts the welding gun and the solder pump. The solder pump pumps out the solder in the solder bin so that the solder covers the gap position, and the welding gun is started to heat the solder to repair the gap; S6: When the CPU module of the signal processor analyzes the defect form as pores and slag inclusions, the welding gun, solder pump and rotating bracket motor are not started. Only the position information of the current defect form is obtained through the displacement sensor, and the position information of the pores and slag inclusions is sent to the staff's terminal for manual inspection and repair by the staff.

[0014] Furthermore, if the waveform of the defect is a sharp pulse and is often accompanied by multiple reflections, and has a high amplitude, a wide bottom, and a stable position, then the defect is in the form of a gap; if the amplitude of the defect is low, the waveform is blunt, and disappears quickly when the probe moves, then the defect is in the form of a pore; if the peak of the defect is blurred, accompanied by a very small wave, and the bottom wave has little influence, then the defect is in the form of a slag inclusion.

[0015] The advantages of the present invention are: 1. First, an ultrasonic transmitter transmits ultrasonic waves toward the outer wall of a seamless tee pipe. An ultrasonic receiver receives the echo, and a signal processor records the echo time difference, echo amplitude, and echo waveform, defining this echo as a standard waveform. 2. Take multiple samples at different positions of the tee pipe and perform standard waveform calibration; 3. The CPU module of the signal processor sends a signal to the drive roller motor and starts the drive roller motor. The drive roller motor drives the drive roller to rotate, and drives the entire moving assembly, including the detection assembly and the outer wall repair assembly, to move simultaneously. 4. When the CPU module of the signal processor determines that a defect exists by analyzing the echo time difference, echo amplitude, and echo waveform pattern, it obtains the current position information through the displacement sensor and stores the current position information in the data storage module of the signal processor; 5. The CPU module of the signal processor analyzes the defect type. If the CPU module determines that the defect type is a gap, it activates the rotating bracket motor so that the rotating bracket rotates in a direction parallel to the cross-section of the tee, causing the movable assembly to rotate circumferentially along the outer wall of the tee. The CPU module also activates the welding gun and solder pump. The solder pump pumps solder from the solder hopper so that the solder covers the gap. The welding gun is then activated to heat the solder and repair the gap. 6. If the signal processor's CPU module analyzes the defect as porosity and slag inclusion, the welding gun, solder pump, and rotating bracket motor will not be activated. Instead, the displacement sensor will be used to obtain the current defect location information. This information will be sent to the operator's terminal for manual inspection and repair.
