This invention discloses an integrated power device combining a low-tooth-difference reducer and a motor, comprising a motor, a housing, and an output shaft coaxially arranged, with the housing rotatably connected to the output shaft. The housing has a hollow cavity inside, into which the motor output shaft extends and is linked via a reduction mechanism. A camshaft is connected to one end of the motor output shaft near the output shaft. The reduction mechanism includes a needle roller bearing mounted on the camshaft, a drive gear mounted on the needle roller bearing, and a transmission assembly installed between the drive gear and the output shaft. The inner wall of the housing has an internal gear ring, with the drive gear meshing with the internal gear ring using low-tooth-difference gears. This invention improves transmission stability and efficiency by designing the motor output shaft and camshaft as an integrated unit, while also making the space more compact. The drive gear and output shaft are driven by transmission steel balls, allowing the output end to directly bear radial force. The structure is simplified, with fewer parts, easier control of part machining accuracy, and lower manufacturing costs.

The utility model discloses a high-precision fire-fighting smoke detection alarm, and relates to the technical field of fire-fighting equipment, the high-precision fire-fighting smoke detection alarm comprises an integration box, a fixed flange and an induction box, the fixed flange is fixedly connected to the top of the integration box, the induction box is fixedly connected to the bottom of the integration box, and a single-chip microcomputer and a buzzer are integrated in the integration box; a detection structure for detecting smoke is arranged between the integration box and the induction box, infrared rays emitted by the infrared ray emitting head can be captured by the infrared ray receiving head, and the infrared rays can be interfered and absorbed by the smoke in the transmission process, so that the smoke can partially block transmission of the infrared rays, and meanwhile, the smoke can be prevented from entering the induction box. When the smoke is emitted, small particles in the smoke scatter, absorb or reflect infrared radiation, so that the transmission capacity of infrared rays is weakened, the more smoke particles are, the more serious the scattering degree of light rays is, the weaker the light intensity received by the infrared receiving head is, and thus the buzzer in the integrated box is triggered to give an alarm.

The application discloses a seawater-induced full-solid waste concrete surface gradient composite corrosion-resistant layer and a forming method thereof. The corrosion-resistant layer is composed of a brucite intermediate layer close to a base body and an outer reaction layer located on a seawater side. The brucite intermediate layer comprises a Mg(OH)2 continuous phase and unreacted slag particles at least partially surrounded by the Mg(OH)2 continuous phase or separated from the base body. The outer reaction layer comprises a calcium carbonate phase and a second inorganic reaction phase containing calcium-silicon-aluminum, magnesium-aluminum or calcium-aluminum. The forming method comprises, in sequence, dilute sulfuric acid surface activation, calcium hydroxide-containing alkaline treatment and bicarbonate mineralization, and seawater immersion curing after each treatment stage. The application utilizes the synergistic reaction of seawater ions and the components of the full-solid waste base body to form an inorganic gradient composite layer in situ on the surface of the base body, so as to reduce the migration ability of the erosion medium to the interior through the pores and microcracks of the surface layer.
