Description

Technical Field

[0001] The invention relates to the field of concrete curing, and in particular to a novel water-saving concrete curing system utilizing atmospheric water. Background Art

[0002] Under the background of the development plan of modern comprehensive transportation system, the scale of transportation infrastructure construction in western my country has been further expanded. The western region is mostly mountainous, with dense mountains and canyons, especially in Tibet, where the average altitude reaches 4,000m, accounting for 85.1% of the total area of ​​the region. Transportation routes inevitably pass through dangerous mountainous areas, and measures such as building various bridges to cross deep canyons are often taken. Due to the environmental characteristics of plateau areas such as dry air, strong ultraviolet rays and high wind speed, concrete structures such as bridge piers are prone to cracking during maintenance. Most bridge piers are set in deep canyons, where hydropower resources are difficult to obtain, and maintenance work is difficult to carry out. Artificial spray maintenance cannot control the humidity of each surface of the bridge pier to be the same, and the maintenance quality is uncontrollable. Therefore, it is urgent to construct an automatic maintenance device for bridge piers that does not require additional external electricity and water to improve the efficiency of maintenance work and ensure the quality of bridge pier maintenance. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art and provide a new water-saving concrete curing system utilizing atmospheric water. When the information processor of the monitoring subsystem determines that the surface humidity of the concrete in the corresponding area photographed by the camera is lower than a set value, the spraying subsystem sprays and cures the corresponding area until the humidity in the corresponding area reaches the set value. When the information processor of the monitoring subsystem determines that cracks exist on the surface of the concrete in the corresponding area photographed by the camera, the control center issues an early warning, thereby effectively realizing precise control of bridge pier maintenance and risk early warning of cracks, thereby greatly ensuring the maintenance quality of the bridge pier concrete and having great promotion value.

[0004] The present invention is achieved through the following technical solutions:

[0005] A new type of water-saving concrete curing system using atmospheric water is used to maintain the piers of a bridge structure, which includes a mobile platform subsystem, a spray subsystem, a monitoring subsystem and a control center, wherein;

[0006] The mobile platform subsystem is arranged on the bridge pier, and the mobile platform subsystem is connected to the bridge pier by sliding up and down, and the spray subsystem and the monitoring subsystem are arranged on the mobile platform subsystem;

[0007] The spray subsystem includes a water storage tank, a water supply pipeline, a water pump and multiple groups of atomizing nozzles. The water inlet of the water supply pipeline is connected to the water outlet of the water storage tank, the atomizing nozzle is connected to the water outlet of the water supply pipeline, the water pump is arranged on the water supply pipeline, and multiple groups of atomizing nozzles are arranged around the bridge piers, and the atomizing nozzles are facing the bridge piers;

[0008] The monitoring subsystem includes multiple sets of cameras and information processors fixedly connected to the mobile platform subsystem. The multiple sets of cameras are arranged around the bridge piers, and the cameras are electrically connected to the information processors. The cameras are used to collect images of the concrete surface of different areas of the bridge piers and transmit them to the information processors for processing and analysis. The information processors send the analysis results to the control center.

[0009] The control center is connected to the monitoring subsystem and the spraying subsystem through a wireless network. When the information processor of the monitoring subsystem determines that the humidity of the concrete surface in the corresponding area photographed by the camera is lower than the set value, the spraying subsystem sprays and maintains the corresponding area until the humidity in the corresponding area reaches the set value. When the information processor of the monitoring subsystem determines that there are cracks on the concrete surface in the corresponding area photographed by the camera, the control center issues an early warning.

[0010] It can be seen that in the above technical scheme, the mobile platform subsystem of the present invention drives the spray subsystem and the monitoring subsystem to move up and down along the bridge pier. The monitoring subsystem is used to collect concrete surface images of different areas of the bridge pier, and process and analyze the concrete surface images. The information processor sends the analysis results to the control center. When the information processor of the monitoring subsystem determines that the concrete surface humidity of the corresponding area photographed by the camera is lower than the set value, the spray subsystem sprays and maintains the corresponding area until the humidity of the corresponding area reaches the set value; when the information processor of the monitoring subsystem determines that there are cracks on the concrete surface of the corresponding area photographed by the camera, the control center issues an early warning, effectively realizing the precise control of the bridge pier maintenance and the risk early warning of cracks, thereby greatly ensuring the maintenance quality of the bridge pier concrete.

[0011] According to the above technical solution, preferably, the mobile platform subsystem includes a climbing formwork track, a lifting platform, multiple groups of spring rod assemblies and a power unit. The climbing formwork track is fixedly arranged on the outer surface of the pier, the lifting platform is vertically slidably connected to the climbing formwork track, the power unit drives the lifting platform to slide up and down, and the multiple groups of spring rod assemblies are arranged between the pier and the lifting platform to adapt to the shape and size changes of the special-shaped piers.

[0014] It can be seen that in the above technical solution, through the setting of each water supply branch and solenoid valve, the spraying effect of each atomizing nozzle can be effectively controlled, the surface humidity of each area of ​​the pier concrete can be accurately controlled, and the maintenance water consumption can be significantly reduced.

[0015] According to the above technical solution, preferably, the information processor has a built-in machine vision analysis module, which determines the concrete surface humidity of the corresponding area and identifies concrete cracks based on the concrete surface image, specifically including the following steps:

[0016] S1: In the early stage, a large number of concrete surface images with different humidity and concrete cracks with different shapes were collected to establish an image dataset, mainly referring to color saturation and gloss to judge the degree of wetness;

[0017] S2: Extract training set, validation set and test set from the image dataset, extract concrete surface features in the training set based on CNN algorithm and train the surface state recognition model;

[0023] When the temperature is low, the heating fan runs to draw cold air from the environment, heats it, and then discharges it from the lower vent of the semiconductor condensation tower, thereby improving the water production efficiency and producing water that is stored in the water tank.

[0024] It can be seen that in the above technical scheme, when the air temperature is high, the temperature difference between the ambient air temperature and the semiconductor condensation tower is large, and the atmospheric water contacts the cooling fins of the condensation tower to condense into liquid water and flows into the storage tank; when the air temperature is low, the temperature difference between the ambient air temperature and the semiconductor condensation tower is small or the ambient temperature is lower than the temperature of the semiconductor condensation tower, and water cannot be condensed normally. The heating fan is operated to extract the ambient cold air, heat it, and then discharge it from the lower vent of the condensation tower.
