Description

Technical Field

[0001] This utility model relates to the field of aluminum electrolysis technology, specifically to a pure water leakage detection system for aluminum electrolysis rectifier cabinets. Background Technology

[0002] Electrolytic aluminum production requires a stable and pure DC power supply, and the rectifier substation is the core location for transforming, rectifying, and filtering the incoming power. The rectifier is one of the key pieces of equipment, and to ensure stable operating temperature, pure water circulation cooling is necessary. Due to the large number of rectifiers and their densely packed joints, leaks in the rectifier water pipe joints become a major challenge in the inspection and maintenance of the rectifier substation. The cooling pipes of the rectifier cabinet may leak due to decreased sealing performance caused by increased pure water temperature. Initially, leaks are difficult to detect due to small leakage flow; they are only detected by observing light reflection when a water layer forms on the lower insulation plate. Accumulated water inside the rectifier cabinet increases internal humidity, potentially affecting the performance of other components. Once a large water layer forms, it is difficult to quickly and accurately locate the leaking pipe joint, requiring individual inspection. Due to spatial constraints and the reliance on manual observation, multiple inspections may be necessary, ultimately leading to significant manpower consumption for troubleshooting, replacement, and repair of leaking joints. There is an urgent need for a high-efficiency detection system that can accurately locate leaks in their early stages. Utility Model Content

[0003] To address the aforementioned issues, this invention provides a pure water leakage detection system for aluminum electrolysis rectifier cabinets, which can quickly and accurately locate the leakage point and reduce manual labor costs.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a pure water leakage detection system for an aluminum electrolysis rectifier cabinet, comprising a power supply device, a leakage detection device, a microprocessor, a communication device, a host computer, and a remote control terminal. The leakage detection device is electrically connected to the power supply device and the microprocessor, the microprocessor is connected to the host computer via the communication device, and the host computer is connected to the remote control terminal. The leakage detection device is disposed between the rectifier circulating water pipe and the water pipe joint, and includes a light-emitting element, a cavity, and a photosensitive sensor. The cavity is disposed between the light-emitting element and the photosensitive sensor and has a water inlet.

[0005] Specifically, the power supply device includes a micro-flow generator and a battery. The micro-flow generator is connected to the battery, and the battery is electrically connected to the leakage detection device and the microprocessor.

[0006] Specifically, the communication device uses LoRa technology for wireless communication.

[0007] Specifically, the remote control terminal includes one or more of mobile phones, computers, and tablet computers.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: By adopting an optical detection method, when water seeps into the cavity, the photosensitive parameters of the photosensitive sensor change, which in turn changes the output current signal of the leakage detection device. The microprocessor transmits the received signal to the host computer through the communication device for feedback, thereby achieving accurate positioning and efficient detection of the leakage location and reducing manual labor. Furthermore, the use of an optical detection method not only accurately detects the leakage situation but also avoids contaminating the detection liquid. Attached Figure Description

[0016] Example 1

[0017] like Figures 1 to 3As shown, this utility model provides a pure water leakage detection system for an aluminum electrolysis rectifier cabinet, including a power supply, a leakage detection device 2, a microprocessor, a communication device, a host computer, and a remote control terminal. The leakage detection device 2 is electrically connected to the power supply and the microprocessor respectively. The microprocessor communicates with the host computer through the communication device. The host computer communicates with the remote control terminal. The leakage detection device 2 is set between the rectifier circulating water pipe 3 and the water pipe joint 1, and includes a light-emitting element 201, a cavity 202, and a photosensitive sensor 203. The cavity 202 is set between the light-emitting element 201 and the photosensitive sensor 203 and has a water inlet.

[0018] Specifically, by employing an optical detection method, when water seeps into the cavity 202, the photosensitive parameters of the photosensitive sensor 203 change, thereby altering the output current signal of the leakage detection device 2. The microprocessor transmits the received signal to the host computer via a communication device for feedback, achieving precise location and efficient detection of the leakage, reducing manual labor. Understandably, a data storage module and an alarm module can be added to the host computer to store and analyze the received data, assess high-risk locations, perform more effective maintenance on these locations, and provide graded early warnings based on the photosensitive intensity received by the photosensitive sensor 203, determining the priority of maintenance for each leakage point and improving maintenance efficiency.

[0019] Specifically, the power supply device includes a micro-flow generator and a battery. The micro-flow generator is connected to the battery, and the battery is electrically connected to the leakage detection device and the microprocessor. The micro-flow generator generates an induced current by passively rotating the generator blades that are in contact with the water flow, which in turn drives the rotor. The induced current is then used by the microprocessor to charge the battery according to its charge requirements.

[0020] Specifically, the communication device uses LoRa technology for wireless communication. Using wireless communication technology can effectively improve information transmission speed.
