  • Publication number: 20250251266
    Abstract: The present disclosure provides a method for measuring flow velocity distribution of groundwater using distributed optical fiber with active heating, comprising: setting and optimizing field test parameters; conducting a background temperature monitoring test; performing a line-source active heating distributed temperature measurement test, including conducting multiple rounds of heating tests; denoising the obtained thermal plume attenuation signal data of the groundwater; and fitting the groundwater velocity-depth curve in the borehole by monitoring and analyzing the temperature difference signal between the internal temperature and the external temperature of the composite heating optical cable in a single depth section of the borehole, thereby obtaining a distributed groundwater velocity data set.

  • Patent number: 12158137
    Abstract: The present disclosure provides a coil pipe device, a liquid cooling system, and a wind turbine. The coil pipe device is used to support a hose, and is arranged between a first platform and a second platform spaced apart. The first platform is rotatable relative to the second platform. The coil pipe device includes a first support, a second support, and a cantilever support assembly, and the first support is fixed on the first platform; the second support is fixed on the second platform. The two ends of the cantilever support assembly are rotatably connected to the first support and the second support respectively, and the cantilever support assembly extends spirally. The cantilever support assembly can be twisted spirally with the rotation of the first platform relative to the second platform.

  • Patent number: 11371921
    Abstract: A clamp and a shear test device are provided, and relate to the technical field of rock mass mechanics tests. The clamp comprises a box body, wherein an opening is formed in one side of the box body, two clamping structures are oppositely arranged in the box body, a sample is arranged between the two clamping structures, each clamping structure comprises an adjusting mechanism, and a distance between the two clamping structures is adjusted through adjusting mechanisms of the two clamping structures. According to the clamp, real-time dynamic adjustment is conveniently and rapidly achieved, the stability of sample clamping is ensured, and therefore the requirement that the shear load can be truly and effectively transmitted to the sample through the box body is met.

  • Patent number: 8987967
    Abstract: An AC claw-pole electric motor includes a casing, a stator connected with the casing, a rotor and two exciting parts. The rotor includes a rotor shaft (9), a center magnetic yoke (11), a first side magnetic yoke (8), a second side magnetic yoke (13), and claw poles (2, 3, 4, 5) provided on the center magnetic yoke (11), the first side magnetic yoke (8) and the second side magnetic yoke (13). The two exciting parts are respectively provided in spaces formed by the center magnetic yoke (11), the first side magnetic yoke (8), the second side magnetic yoke (13) and the claw poles (2, 3, 4, 5). The axial exciting magnetic fluxes of the two exciting parts are opposite in direction. Thus, the main magnetic flux and the magnetic energy product of the electric motor are increased, and the output and the operation efficiency of the electric motor at a low speed are improved.
