Description

Technical Field

[0001] This utility model relates to the field of intelligent concrete curing technology, and more specifically, to an intelligent curing device for wind turbine foundation concrete based on temperature and humidity self-adaptation. Background Technology

[0002] As the core load-bearing structure supporting the entire wind turbine, the quality of the concrete construction and its long-term durability directly determine the safe operation and overall service life of the wind farm. The curing process after concrete pouring is a crucial step in regulating its strength development, inhibiting crack initiation, and ensuring the final service performance of the structure. Especially for large-volume concrete foundations, precisely controlling the temperature difference between the inside and outside of the structure and maintaining uniform humidity in the curing environment are core technical challenges in curing implementation. Inadequate curing measures can easily lead to structural cracks due to temperature stress or surface shrinkage cracks due to insufficient humidity. Such defects will seriously jeopardize the long-term safety and stability of the wind turbine's operation.

[0003] Current technologies face significant bottlenecks: in complex environments lacking stable energy supplies in the field, it is difficult to achieve precise and adaptive control of core parameters for concrete curing; at the same time, the relevant technical system lacks an efficient and reliable remote monitoring mechanism. This makes the concrete curing process highly dependent on manual operation, resulting not only in poor controllability of curing quality but also harboring numerous safety risks, severely restricting the standardized construction of wind farm foundation engineering.

The control circuit board of the early warning management module is electrically connected to the control center module through wiring terminals.

[0021] The working process of this utility model is as follows: I. Energy Supply The energy supply module is preferentially connected to the mains power. The mains power is stepped down by an isolation transformer and regulated by a voltage regulator circuit before supplying power to each module. During the day when there is sufficient sunlight, the photovoltaic modules receive solar energy. After processing by the controller, one circuit provides supplemental power, and the other circuit charges the battery pack. When the mains power is interrupted, the system automatically switches to battery power. When sunlight is insufficient, the system switches to a hybrid power supply of mains and photovoltaics to ensure that there is no risk of power outage. II. Parameter Acquisition After the temperature and humidity monitoring module is activated, the installed temperature and humidity sensors synchronously collect the concrete temperature and humidity parameters. The sensor output signal is amplified and filtered by the conditioning circuit board, converted into a digital signal by the data acquisition unit, temporarily stored in the local processing unit, and then transmitted to the control center module via RS485 bus. III. Signal Processing The real-time control core of the control center module receives monitoring data, generates a sprinkler start command, and transmits the command to the water supply execution module via the terminal block. At the same time, some data is transmitted to the management core for storage. IV. Action Execution After receiving the command, the drive unit of the water supply execution module triggers the power circuit to control the booster pump to start. The water in the tank is filtered and flows into the ring main pipe, and then sprays the concrete evenly through the nozzles via the branch pipes. If temperature control is required, the drive unit controls the PTC heater to heat or the fan to ventilate. The overcurrent protection chip ensures the safety of the equipment. V. Data Transmission The remote communication module receives system data from the control center and uploads it to the cloud platform, SCADA system, or connects with field equipment via 4G / LTE, Ethernet, or LoRa modules. When receiving remote control signals, it transmits them to the control center to adjust equipment operation. Data is automatically cached in case of communication interruption and retransmitted after network recovery. VI. Abnormal Warning The early warning management module receives abnormal signals from the control center and triggers indicator lights and buzzers according to the level of abnormality. For example, a low battery triggers a green indicator light, a sensor malfunction triggers a yellow warning light and an intermittent buzzer, and a double power failure triggers a red emergency light and a high-frequency buzzer, ensuring timely handling of abnormalities. The foregoing has shown and described the basic principles, main features, and advantages of this utility model.
