The application provides a baffle, an expansion card containing the baffle and an electronic device. The expansion card is suitable for a case of the electronic device and includes a circuit board and the baffle. The baffle includes a baffle part and an assembling part. The baffle part is fixed to the circuit board. The assembling part is detachably clamped to the baffle part and is suitable for being combined with the case, so that the expansion card is assembled to the electronic device through the assembling part.

This utility model relates to the field of metering box technology, specifically to an electricity metering box that facilitates user data reading. It includes a metering box with an electricity meter fixedly connected inside. A protective door is hinged to the surface of the metering box to protect the electricity meter. An amplifying component is slidably disposed on the inner wall of the protective door. The amplifying component includes a connecting frame slidably connected to the inner wall of the protective door. The connecting frame drives the amplifying component to slide along the inner wall of the protective door. By sliding the connecting frame of the amplifying component, the amplifying component is moved closer to the electricity meter, increasing the magnification and avoiding blurred readings due to insufficient magnification. When the digit display size is large, the sliding connecting frame moves the amplifying component away from the electricity meter, reducing the magnification and preventing the digits from exceeding the field of view and becoming incompletely displayable. This ensures that digits of different sizes can be clearly and completely observed without the observer needing to open the protective door.

This invention proposes a domain-adaptive method for dehazing coal mine dust and fog images with partial parameter sharing. The method includes: constructing a coal mine dust and fog image dataset; building a domain-adaptive dehazing network framework with partial parameter sharing; supervised training of a loss function for synthetic dust and fog images; enhancement of real dust and fog images followed by unsupervised adversarial training; designing an enhancement module for real dust and fog images followed by supervised training; and obtaining the dehazed coal mine dust and fog images. The method provided by this invention effectively alleviates the problem of poor generalization ability of deep networks trained on synthetic data on real coal mine dust and fog images, thus improving the visual effect of the images.

This invention discloses a method for recycling TAIC wastewater and extracting 1,3-diallylurea, belonging to the field of industrial wastewater treatment and resource recovery technology. The method comprises five steps: alkaline hydrolysis, vacuum distillation, filtration, filtrate recycling, and filter residue refining. First, NaOH or KOH alkaline solution is added to the TAIC wastewater, and alkaline hydrolysis is performed by heating and aeration at 60-80℃, with the escaping gas absorbed by acid. Then, vacuum distillation is carried out at 60-70℃ and -0.05~-0.08 MPa, and the resulting distillate can be reused in production. The concentrated mother liquor is cooled and filtered, and the filtrate is replenished with fresh wastewater and alkaline solution before recycling for alkaline hydrolysis. The filter residue is then dissolved and recrystallized at 45-50℃ to obtain high-purity 1,3-diallylurea. This process achieves closed-loop wastewater recycling, with virtually no external wastewater discharge. It effectively degrades high COD and high ammonia nitrogen pollutants in the wastewater while recovering high-value-added products. Both water resources and refining water can be recycled, resulting in low operating costs, stable processes, and both environmental and economic benefits.
