Description

Technical Field

[0001] This invention relates to the field of bridge engineering technology, and in particular to a suspension bridge main cable exhaust clamp structure with condensate removal function. Background Technology

[0002] The main cable is a critical load-bearing component of a suspension bridge, often referred to as its "lifeline." However, the main cable is constantly exposed to the environment, and current cable protection systems suffer from poor durability and are prone to sealing failure. Harmful moisture and ions can enter the cable, corroding the steel wires and causing strength loss, seriously affecting the structural safety of the bridge. The temperature and humidity of the air inside the main cable of a suspension bridge are key factors affecting steel wire corrosion.

[0003] Dehumidification of the main cables of suspension bridges is a crucial issue that countries worldwide are striving to address. Currently, dehumidification systems based on dry air injection are widely used. The basic principle is as follows: First, the dehumidification equipment generates dry air. Then, the dry air is delivered into the main cable through air delivery pipes and air clamps, creating a pressure difference between the delivered dry air and the air inside the main cable. This causes the dry air to circulate within the main cable, expelling some of the moisture through the air delivery clamps, thereby reducing the humidity inside the main cable and ultimately preventing corrosion of the main cable wires.

[0004] Patent CN201420277613.5 discloses an air clamp for bridge cables that facilitates air intake and exhaust and maintenance. This patented air clamp consists of two semi-circular outer shells joined together to form a cylindrical shape, and includes an observation window. In bridge main cable dehumidification systems, the exhaust air clamp is a critical component, as it collects humid air from both ends of the main cable. This humid air easily condenses and adheres to the walls of the exhaust air clamp. Since the cable wires at the exhaust air clamp are directly exposed, they are prone to corrosion. Although patent CN201420277613.5 considers providing a drainage hole at the bottom of the air clamp, this is not effective in cleaning the condensate adhering to the clamp walls.

[0005] This invention addresses the prominent problem of exhaust air clamps in bridge main cable dehumidification systems by proposing an exhaust air clamp structure for suspension bridge main cables with condensate removal function. Summary of the Invention

The upper semi-circular arc slider reciprocates on the upper semi-circular arc slide rail, thereby driving the upper semi-circular arc-shaped water-absorbing strip to reciprocate and wipe the inner wall of the air clamp, absorbing the condensate on the inner wall of the upper semi-circular arc air clamp. When the upper semi-circular arc slider drives the upper semi-circular arc-shaped water-absorbing strip to the upper semi-circular arc-shaped water collection tank, the upper semi-circular arc-shaped water-absorbing strip squeezes the inner wall of the upper semi-circular arc-shaped water collection tank, thereby squeezing out the condensate absorbed by the upper semi-circular arc-shaped water-absorbing strip. The condensate flows through the upper semi-circular arc drain hole set in the baffle plate at the end of the upper semi-circular arc-shaped water collection tank to the bottom of the lower semi-circular arc air clamp and is discharged from the drain hole set in the lower semi-circular arc air clamp.

A lower semi-circular arc-shaped water collection trough end baffle is provided at the end of the lower semi-circular arc-shaped water collection trough. The lower semi-circular arc slider can be driven by a cylinder to slide along the lower semi-circular arc. The number of cylinders is determined by the number of sliders and fixed at both ends of the lower semi-circular arc air clamp. The lower semi-circular arc slider reciprocates on the lower semi-circular arc slide rail, thereby driving the lower semi-circular arc-shaped water-absorbing strip to reciprocate and wipe the inner wall of the air clamp, absorbing the condensate on the inner wall of the air clamp. The lower semi-circular arc-shaped water collection groove is located at the end. When the lower semi-circular arc slider drives the lower semi-circular arc-shaped water-absorbing strip to the lower semi-circular arc-shaped water collection groove, the lower semi-circular arc-shaped water-absorbing strip squeezes the inner wall of the end of the lower semi-circular arc-shaped water collection groove, thereby squeezing out the condensate absorbed by the lower semi-circular arc-shaped water-absorbing strip and discharging it from the first drain outlet and the second drain outlet provided on the lower semi-circular arc shell.

A second exhaust valve 604, a second airflow check valve 605 and a second intelligent detector 606 are disposed on the second exhaust pipe 601.

[0040] The first and second airflow check valves are used to prevent humid outside air from flowing back into the exhaust pipe in extreme windy and rainy weather conditions.

[0041] A working method for a suspension bridge main cable venting air clamp structure with condensate removal function:

[0042] S1. Main Cable Cleaning. Remove the protective layer and wrapping wires of the main cable at the location where the exhaust clamp is installed, and embed the air guide plate into the main cable wire to expand the main cable so that the gas can be discharged smoothly.

[0043] S2. Installation of exhaust air clips. Use anchor bolts to connect and anchor the upper and lower semi-circular arc air clips through the bolt holes at the flange plate, and apply sealant between the first arched rib and the main cable, between the second arched rib and the main cable, and between the flanges of the upper and lower semi-circular arc air clips.

[0044] S3. Exhaust with air clamp. Dry air is introduced into the first and second main cable sections respectively. The exhaust valves of the first and second exhaust systems are opened to ensure normal exhaust operation. The temperature, humidity, air pressure, flow rate and other parameters of the gas in the first and second compartments are detected by the exhaust detection box to determine the temperature and humidity conditions of the gas in the first and second main cable sections.

[0045] S4. Condensate Removal Device in Operation. When condensate appears on the air clamp wall, the condensate removal device of the air clamp starts to work. The slider, carrying the arc-shaped water-absorbing strip, moves back and forth along the slide rail, continuously wiping the air clamp wall and absorbing the condensate on the air clamp wall. When the slider drives the arc-shaped water-absorbing strip to the arc-shaped water collection tank, the arc-shaped water-absorbing strip squeezes the inner wall of the end of the arc-shaped water collection tank, thereby squeezing out the condensate absorbed by the water-absorbing strip and discharging it from the drain hole.

[0046] Therefore, the present invention adopts a suspension bridge main cable exhaust air clamp structure with condensate removal function, which overcomes the prominent problems of the exhaust air clamp of the existing bridge cable dehumidification system. The air clamp is equipped with a condensate removal device, which can clean the condensate on the inner wall of the air clamp at any time, effectively slowing down the corrosion of the main cable steel wire at the exhaust air clamp.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
