The utility model discloses a new energy automobile power battery temperature monitoring early warning and forced power-off device belongs to new energy automobile power battery temperature monitoring field, through two groups of normally open thermal switch setting different temperature response threshold value, when battery temperature reaches primary early warning threshold value, immediately through four foot normally open relay and three foot flash relay linkage trigger early warning horn ringing and emergency double flash lamp scintillation, provide clear sound and light early warning signal for driver, compared with the single software alarm of traditional BMS, send risk prompt in advance, greatly increase the time window of manual intervention, when temperature further increases to emergency power-off threshold value, high voltage contactor rapidly cuts off power battery main positive loop's high breaking fuse, through physical level power-off forced termination energy output, even in the extreme situation of BMS communication interruption or controller failure, still can ensure power-off reliability.

The invention relates to the technical field of nano-materials, in particular to a polypeptide nano-material for binding HER2 and a preparation method and application thereof, the polypeptide nano-material comprises polypeptide with an amino acid sequence as shown in SEQ ID NO: 1 and an I-type photosensitizer connected with the last amino acid of the polypeptide; the polypeptide comprises a ligand unit and a fiber deformation element; the I-type photosensitizer is connected to one end, deviating from the ligand unit, of the fiber deformation element, and the I-type photosensitizer has the aggregation-induced emission characteristic. The polypeptide nano-material can be self-assembled in an aqueous solution through hydrophilic and hydrophobic effects to form spherical nano-particles, the spherical nano-particles are disintegrated through ligand-receptor interaction induction, and an ordered, stable and continuous beta-folding structure is formed through a pi-pi accumulation effect and a hydrogen bond, so that the polypeptide nano-material is converted into a nanofiber network structure in situ in a tumor, and the tumor activity is improved. The type and intensity of active oxygen generated by the I-type photosensitizer with AIE characteristics can be remarkably improved, and finally, specific efficient photodynamic therapy of HER2 positive breast cancer is realized.

The utility model relates to the technical field of frit processing devices, and discloses a frit processing gathering rod capable of reducing heat loss, which comprises a reference gathering rod, a gathering ball is arranged on the right side of the reference gathering rod, a threaded rod is fixedly connected to the right side of the reference gathering rod, a threaded groove is arranged on the left side of the gathering ball, and the threaded rod is fixedly connected to the right side of the reference gathering rod. The threaded rod is detachably connected into an inner cavity of the threaded groove, the diameter of the section of the threaded rod is set to be 1 cm, a protection mechanism is arranged on the left side of the reference gathering rod and comprises a hollow cylinder, the hollow cylinder is fixedly connected to the left side of the reference gathering rod, and an annular aluminum foil heat insulation pad is fixedly connected to the right side of the hollow cylinder. The diameter of the section of the threaded rod is set to be 1cm, so that the heat loss of the glass material on the surface of the gathering ball can be reduced, the heat preservation of the gathering ball is facilitated, the heat loss and the energy consumption are reduced, the glass forming time window is prolonged, and the economic benefit is improved.

This invention discloses an impregnation device for prepreg resin and its method of use, relating to the field of resin impregnation technology. The device comprises, in sequence according to the direction of fiber cloth feeding, a front traction roller, an impregnation tank, an extrusion roller, a pre-curing oven, and a rear traction roller. The impregnation tank contains a resin solution and a guide roller is disposed within it. The extrusion roller is positioned above the impregnation tank and behind the guide roller, and its edge is equipped with a fixed scraper along its axial direction for scraping off excess resin from the upper surface of the fiber cloth. This invention fundamentally solves the problems of uneven resin distribution along the thickness direction of the fiber cloth, insufficient resin at the edges and bottom, and the inability to expel closed-cell microbubbles in existing processes, significantly improving the interlayer bonding strength and overall density of the prepreg.

This invention discloses a method for shade cultivation of saffron in high-altitude areas, relating to the field of saffron cultivation technology. Specifically, it includes seedling selection, planting selected seedlings in the field, erecting a shade net above the field to control the shading rate (75%–85%), and watering, fertilizing, and pest and disease control under the shade net. This method solves the technical problems of complex understory lighting conditions, the unclear adaptation threshold and suitable shading range for saffron to low-light environments, and the lack of scientific parameter support for understory cultivation. Using this method, a root zone and canopy environment with coordinated light, temperature, and water is created for saffron growth. The S80 method of this invention extends the entire growth period of saffron to 260–280 days, increasing the time window for photosynthetic product accumulation, effectively maintaining bulb fresh weight and diameter, and providing sufficient energy and material basis for flower development and bulb enlargement. Furthermore, its medicinal value meets and exceeds the standards of the 2020 edition of the Chinese Pharmacopoeia.
