The invention belongs to the technical field of automatic water replenishing for boiler blow-off water tanks, and particularly relates to an automatic water replenishing device for a boiler blow-off water tank, which comprises a fixed tank, a first water inlet is fixedly connected to the upper surface of the fixed tank, a first water outlet is fixedly connected to the upper surface of the fixed tank, a second water inlet is formed in one side of the fixed tank, and a second water outlet is formed in the other side of the fixed tank. A first water outlet is formed in one side of the fixing box, a second water outlet is formed in the other side of the fixing box, a first cavity is formed in the fixing box, a fixing frame is fixedly connected to the interior of the fixing box, a second cavity is formed below the fixing frame, and a heat exchange assembly is arranged on the upper surface of the fixing box. And the heat exchange assembly comprises a plurality of positioning pipes fixedly connected to the lower surface of the fixing frame, the section of each positioning pipe is rectangular, a fixing groove is formed in each positioning pipe, and by arranging the stirring assembly and the heat exchange assembly, the problem that the sewage discharge well can be damaged by high-temperature sewage is solved.

The battery protection structure for the flashlight comprises a battery mechanism and a protection mechanism, the protection mechanism is arranged on the outer side of the battery mechanism, the protection mechanism comprises a protection box, the inner side of the protection box is fixedly connected with an insulation pad, the bottom of the inner wall of the protection box is fixedly connected with a motor, and the motor is fixedly connected with the battery mechanism. The output end of the motor is fixedly connected with a first bevel gear, the left side of the inner wall of the protection box is movably connected with a threaded rod through a bearing, the right side of the threaded rod is movably connected with the inner wall of the protection box through a bearing, and the surface of the threaded rod is sleeved with a second bevel gear. Through the arrangement of the protection mechanism, the situation that a traditional battery mechanism is possibly subjected to external force or makes contact with air to cause battery damage or electric quantity reduction when placed is changed, the battery can be protected and prevented from being damaged by the external force, and the natural loss of the electric quantity stored in the battery can be delayed; and the battery can be stored for a longer time.

The utility model relates to an anti-explosion movable device for analyzing hydrogen in chlorine, which can perform rapid detection on a production site by arranging an anti-explosion movable power supply, and solves the potential safety hazard of movement of an Orsi gas analyzer. Meanwhile, analysis can be carried out without limitation of places, dependence on a fixed power socket is reduced, and the method is suitable for analysis of hydrogen in chlorine in an on-site explosion-proof area.
