This invention provides a front-end treatment device for electroplating wastewater contaminated with heavy metals, relating to the field of electroplating wastewater technology. The device includes a first treatment chamber, a transmission chamber, a mounting rod, a permanent magnet, a connecting rod, a second treatment chamber, a connecting pipe, and a stirring assembly. This invention uses neodymium iron boron (NdFeB) permanent magnets as the core element for heavy metal adsorption. These magnets possess extremely strong magnetic adsorption properties, rapidly adsorbing magnetic heavy metal ions such as iron, nickel, and cobalt, as well as pollutants containing magnetic components, from electroplating wastewater. Simultaneously, the permanent magnets are driven by a swing assembly to oscillate reciprocally at an angle of 30–60°. Combined with the opposite polarity of adjacent permanent magnets, a dynamically changing magnetic field environment is formed. This not only expands the magnetic field coverage but also avoids the formation of adsorption saturation regions, significantly improving the capture efficiency of heavy metal ions. The titanium alloy or polyvinyl chloride corrosion-resistant protective shell on the outer surface of the permanent magnets ensures magnetic stability and extends service life, guaranteeing long-term and efficient heavy metal separation.

The utility model provides a split formula combined distribution box relates to distribution box technical field, including split mechanism, split mechanism includes box one, the one end of box one sets up box two, the one end of box one and the one end of box two corresponding contact, the one end of box two is provided with the carousel, the inside of box two and the center of carousel swing joint. The utility model fixes the fixed plate on the wall surface, makes the assembly board and the abutting board get the support, then, the box one and the box two are combined from different directions, make the assembly board be located in the inside of both, through the outside force to convex rod, let the movable arm drive carousel produce ninety degrees rotation, thereby lock rod and the bite disc complete the joint, ensure that the box one and the box two always keep firm and reliable through the structure connection of lock rod and bite disc, this way makes when replacing the box one and the box two, do not need to dismantle the electrical on the assembly board, need not interrupt the connection of electrical element.

This utility model discloses a lead-fish current measurement cableway, including a lead-fish, a vehicle body, two towers, two main cables fixed between the two towers, and multiple guide tubes. Two pulleys with grooves are rotatably connected to opposite sides of the vehicle body via support shafts. The main cables are embedded in the grooves of the pulleys. Winches are fixedly connected to both towers, and each winch has a shaft. One winch shaft is wound with a first cable, one end of which is fixedly connected to one side of the vehicle body. The other winch shaft is wound with a second cable, and the other side of the vehicle body is connected to the second cable via an installation port. A through hole is provided at the lower end of the vehicle body. This utility model effectively simplifies the structure of hydrological monitoring equipment, reduces the weight of the equipment on the main cables, reduces the likelihood of malfunctions preventing the equipment from being retrieved, and facilitates maintenance by technicians.
