Provided is a machine room inspection robot, comprising a robot body, propellers, supporting rods, a top protection plate, a protection ring, elastic pieces, a control part, distance sensors, connecting rods, walking wheels and rotating shafts. The robot body is an unmanned aerial vehicle of a circular structure when overlooked. Propellers are respectively arranged on two sides of the top of the robot body. A supporting rod is arranged at the top of the robot body. A top protection plate is arranged at the tops of the supporting rods. A protective ring is arranged on the periphery of the robotbody. The protection ring is connected with the robot body through an elastic piece, a distance sensor is arranged on the periphery of the top of the robot body, a control part is arranged in the robot body, the distance sensor is electrically connected with the control part through a cable, connecting rods are symmetrically arranged at the bottom of the robot body relative to the center line, and walking wheels are arranged at the bottom ends of the connecting rods. The robot has the advantages that the inspection mode that a traditional inspection robot can only shuttle and walk on the ground for inspection is changed, the moving range of the robot is not limited by ground obstacles, and certain flexibility is achieved.

Provided is an environment-friendly mobile collecting box for decoration cutting dust. The mobile collecting box comprises a box body, wherein a water tank is fixedly mounted on one side of the bottomsurface of the inner wall of the box body, the bottom surface and the outer side of the water tank are fixedly connected to the inner wall of the box body separately, the inner side of the water tankis fixedly connected to one side of the box body, and openings are formed in the top surface and the other side of the box body; a first through hole is formed in the bottom of the inner side of theinner wall of the water tank, a switching valve is disposed in the first through hole, and a second through hole is formed in one side of the box body; the interior of the first through hole communicates with the interior of the second through hole, and the second through hole communicates with the interior of the box body; the top surface of the water tank is fixedly connected to one end of a hose, and the other end of the hose is arranged in the box body, and a floating plate is fixedly mounted on the periphery of the other end of the hose. Sediment in the box body can be pushed directly into the garbage bag through cooperative use of a mud box and a garbage bag, and the mud box can be taken and placed freely; after the mud box is taken out, a sealing cap of the garbage bag containing the sediment is removed, and after the garbage bag is replaced by a new garbage bag, the mud box is put back, and the sediment is not in contact with the mud box, and cleaning of the mud box by a user is not needed, so that time and labor are saved.

The invention relates to the technical field of medium-frequency induction heating furnaces, in particular to a medium-frequency induction heating furnace body, a furnace body manufacturing method anda temperature control method. The medium-frequency induction heating furnace body comprises a furnace lining, a material channel allowing a blank to pass through is formed in the middle of the furnace lining, and an induction coil which extends in axial direction of the material channel and is spirally wound on outer side of the material channel is arranged in the furnace lining; and a pluralityof temperature measuring holes are formed in the side wall of the furnace lining in the axial direction of the furnace lining at intervals, the temperature measuring holes are formed in the radial direction of the furnace lining and penetrate through the side wall of the furnace lining, and the temperature measuring holes are located at the intervals between every two adjacent turns of coils of the induction coil. The invention further provides a manufacturing method of the medium-frequency induction heating furnace body and a temperature control method of the medium-frequency induction heating furnace. According to the furnace body, the temperature measuring holes are formed in the side wall of the furnace body for temperature measurement instead of adopting the temperature measurement mode at a discharge port so that the temperature measurement accuracy can be improved.
