The invention discloses a reflector device for a turning blind area of a traffic curve. The reflector device comprises a base, a supporting frame is arranged on the base, and a positioning ring is arranged at the top of the supporting frame. A reflector is arranged at the position of the positioning ring, a positioning shaft is arranged on the positioning ring, and a coil pipe sleeves the peripheral surface of the positioning shaft and is installed on the back of the reflector. Positioning shells are arranged at one side of the supporting frame, clamping mechanisms are arranged on the positioning shells, and one side of the reflector is clamped in the clamping mechanisms. A supporting mechanism is arranged between the positioning shells and comprises a back frame, a supporting seat is arranged on the back of the reflector, and a magnetic attraction plate is arranged on the front face of the supporting seat and is fixed to the back of the reflector. A positioning pipe is arranged on theinward face of the back frame and sleeves an adjusting shaft, and the end of the adjusting shaft is connected with the back of the supporting base. According to the invention, the reflector can be flexibly adjusted, and the visibility of a curve turning blind area of a municipal road can be greatly improved through the reflector, so that the safety is greatly improved.

The invention discloses a helical blade rolling mill which comprises a stand, and two ends of the stand are symmetrically arranged; a fixed shaft is horizontally arranged along two ends of the stand, a support seat is symmetrically hinged at the approximately middle part of the fixed shaft, an angle adjusting device is arranged at the lower end of the support seat, and axial moving devices are symmetrically arranged along two sides of the support seat; a sliding seat which can slide up and down along the support seat is arranged at the outer side of the support seat, a main shaft driven by a power driving mechanism is arranged in the sliding seat, and tapered rollers are arranged at the upper end of the main shaft; and feeding devices and discharging devices are oppositely arranged at twosides of the tapered rollers. In the invention, as two rollers are supported on the same fixed shaft by the support seat, the central axial lines of the two rollers can be ensured to be coplanar as long as two sliding seat mounting holes on the support seat are ensured to be coaxial; as the helical blade rolling mill adopts the structure, the two sliding seat mounting holes are very easy to be coaxial, and the central axial lines of the two rollers have simple planar structure and are convenient for aligning; and the support seat is hinged on the fixed shaft, thereby having good adjusting stability.

The invention relates to an underwater verticality adjustment device of an acoustic Doppler current profile (ADCP) sensor, and belongs to the field of hydrologic monitoring. A worm and gear speed changing box is fixedly arranged on a fixed framework which is fixed on a prefabricated foundation, a sleeve of a rocker arm mechanism is in clearance fit with a worm-wheel shaft of the worm and gear speed changing box, a cross axle adjustment mechanism is installed on the fixed framework, the ADCP sensor is arranged on the cross axle adjustment mechanism and is fixedly connected with a linear bearing and a guide rod mechanism of the linear bearing, one end of a transmission mechanism 7 abuts against the sleeve of the rocker arm mechanism, the other end of the transmission mechanism is connected with the linear bearing and the guide rod mechanism of the linear bearing, and the worm and gear speed changing box and the rocker arm mechanism are provided with tensioning mechanisms. The device has the advantages of being small in size, light in weight, precise in positioning, and convenient to install, adjust and maintain, and the like; adjustment stability in the horizontal direction and the vertical direction is good; and compared with the prior art, the device is precise in positioning, can guarantee completeness and reliability of hydrologic data collection, has a self-lock function, and is simple and novel in structure, convenient to use, and strong in practicability.

The invention discloses a preparation method of a porous spherical compound humidifying agent, which comprises the following steps of: a, activating zeolite for 2-3h at a temperature of 450 DEG C to obtain activated zeolite; b, adding 30 parts by mass of polyacrylic acid into a sodium hydroxide solution prepared from 15 parts by mass of sodium hydroxide and 100 parts by mass of distilled water so that polyacrylic acid is neutralized, then adding 0.9-2.7 parts by mass of sodium carboxymethylcellulose, 3-6 parts by mass of activated zeolite and 0.3 part by mass of potassium persulfate into a container containing the solution, stirring for reaction at a temperature of 70-80 DEG C; 30min later, dissolving 0.3 part by mass of aluminium chloride in 10 parts by mass of distilled water to obtain a solution, adding the solution in the reactor; adding 0.3 part by mass of N,N-methylenebisacrylamide, continuously stirring for reaction for 0.5-1h till a gel effect happens; and c, adding 0.9 part by mass of sodium bicarbonate into the reactor to generate aluminium hydroxide and carbon dioxide, carrying out primary foaming, stirring for reaction for 0.5-1h to obtain a synthetic product; heating for 1-2h at a temperature of 150 DEG C so that the aluminium hydroxide is decomposed and water is evaporated, and carrying out secondary foaming and drying to obtain the porous spherical compound humidifying agent.
