Description

Technical Field

[0001] This utility model belongs to the field of water resource utilization technology and relates to an automated water diversion system for basement water accumulation. It is suitable for the automated collection, filtration and recycling of water accumulation in basements of industrial production bases (such as power plants, oxygen plants, etc.) to achieve water conservation and production cost reduction. Background Technology

[0002] With rapid industrialization, the efficient utilization of water resources has become a global focus. In industrial production bases, such as power plants, oxygen plants, and chemical plants, basements, often located in low-lying areas, are frequently affected by surface water or groundwater infiltration, leading to frequent water accumulation. For example, the Changshou Oxygen Plant base of Chongqing Chaoyang Gas Co., Ltd. experiences daily water infiltration of up to 300 cubic meters in its basement. If this water is not properly treated, it not only occupies space but may also cause long-term damage to basement equipment and structures. Traditional methods often involve pumping the water directly into rainwater wells or external drainage systems. While this method can temporarily solve the water accumulation problem, it has significant drawbacks: First, the pumping process continuously consumes electricity, increasing the company's operating costs; second, direct discharge leads to a waste of a large amount of usable water resources, failing to achieve recycling in production; furthermore, frequent pumping operations may accelerate equipment wear and tear, increasing maintenance costs.

[0003] Existing technologies include some water diversion or drainage systems for dealing with basement water accumulation, but they generally have the following shortcomings:

[0004] Lack of automated control: Traditional water diversion systems rely heavily on manual operation or simple timed switches, making it difficult to adjust their operating status in real time according to the amount of water accumulated. For example, a fixed-power water pump may still run at full power when the water volume is low, resulting in energy waste; manual monitoring is inefficient and increases labor costs.

[0005] Insufficient water quality adaptability: Basement water often contains silt, suspended solids, or other pollutants, and direct diversion to production water systems (such as cooling water tanks) may affect water quality stability. Existing systems typically lack effective water quality monitoring and filtration mechanisms, resulting in diverted water quality that fails to meet industrial water standards, necessitating additional water treatment processes and increasing costs.

[0006] Poor installation and structural compatibility: Many water diversion devices require modifications to the original civil structure of the basement during installation, such as excavating pipe channels or reinforcing the foundation. This not only increases the difficulty of construction but may also damage the integrity of the building and increase safety hazards.

[0007] Low system integration: Existing water diversion systems often focus only on a single function (such as pumping or diverting), failing to achieve integrated management of water collection, filtration, monitoring, and diversion. For example, some systems are equipped with filtration devices, but lack self-cleaning functions, making the filter screens prone to clogging and requiring frequent manual maintenance; also, there is a lack of linkage between water quality monitoring and diversion control, causing the system to be unable to dynamically adjust the diversion path according to water quality.

[0008] In recent years, with the development of automation and IoT technologies, some new drainage systems have begun to incorporate sensors and controllers to achieve a certain degree of intelligence. For example, some commercial drainage pumping stations are equipped with level sensors that can start or stop pumping based on water levels. However, these systems still primarily focus on drainage, with less consideration given to the recycling of accumulated water, and their filtration and water quality management functions are insufficient, making it difficult to meet the demands of industrial scenarios for efficient water resource utilization. Furthermore, the filtration devices in existing systems are mostly designed as fixed units, lacking dynamic cleaning mechanisms, leading to a decline in filtration efficiency after long-term operation and affecting system stability.

[0009] To address the aforementioned issues, there is an urgent need for a basement water diversion system that integrates automated control, high-efficiency filtration, water quality monitoring, and structural compatibility to achieve precise collection, treatment, and recycling of accumulated water. Such a system would not only significantly reduce industrial water costs but also minimize water waste, aligning with the principles of sustainable development. For example, in the application scenario at the Chongqing Changshou Power Plant, effectively recycling 300 cubic meters of accumulated water daily to a cooling water tank could save hundreds of thousands of yuan in water costs annually, while simultaneously reducing electricity consumption and maintenance costs, demonstrating significant economic and social benefits. However, currently available technical solutions do not offer a comprehensive system that simultaneously addresses these issues. Therefore, developing a highly integrated, efficient, and adaptable automated basement water diversion system has become a pressing technical challenge in this field. Utility Model Content
