The invention discloses a rectifier data processing system and method, and relates to the technical field of rectifiers, and the system comprises the following modules: a state monitoring module which obtains the input voltage of a rectifier, obtains the output current of the rectifier, obtains the power factor of the rectifier, and obtains a state coefficient through the input voltage, the output current and the power factor of the rectifier; the state coefficient and the stability coefficient are combined through the rectifier early warning module to obtain a prediction coefficient, the future working state of the rectifier is accurately predicted by combining external influence factors and internal working factors of the rectifier, and whether an early warning alarm is started to remind a manager is judged through the prediction coefficient and a prediction coefficient preset threshold value. Therefore, early warning feedback can be conveniently carried out to a manager according to a prediction result, early warning can be further conveniently carried out before the rectifier stops working, and sufficient response time is provided for an operator to replace and maintain the rectifier.

The application provides a saw blade with staggered saw teeth, a saw blade production process and equipment, and relates to the technical field of composite material cutting processing. The saw blade with staggered saw teeth comprises a circular saw body, a plurality of first saw tooth portions and a plurality of second saw tooth portions are staggered along the circumferential direction on the outer periphery of the circular saw body, the first saw tooth portions and the second saw tooth portions are equal in number and are arranged in sequence with intervals, the first saw tooth portions and the second saw tooth portions are staggered with each other, so that staggered cutting structures are formed between adjacent different types of saw teeth. The structure is beneficial to dispersing cutting force, reducing the load of a single saw tooth, improving the stability and durability of the saw blade, and facilitating the fracture and discharge of chips, thereby improving the cutting efficiency and processing quality.

The utility model discloses an automobile clutch pressure plate wear resistance testing device, which belongs to the technical field of automobile clutch pressure plate wear resistance testing, and comprises a connection detection mechanism, a lifting assembly, a rotating assembly, a dust removal assembly, a detection box, a base and a display control panel, the detection assembly can limit the connecting assembly, and the connecting assembly can play a certain buffering role when the wear resistance of the automobile clutch pressure plate is detected, so that the load borne by the device is reduced, and the wear resistance of the automobile clutch pressure plate can be tested in cooperation with the detection assembly. The lifting assembly can perform lifting adjustment on the connection detection mechanism, so that the data of the wear resistance test of the automobile clutch pressure plate can be obtained by increasing the pressure, the rotating assembly can be matched with the connection detection mechanism for use and imitate the friction of the automobile clutch pressure plate, and the dust removal assembly can clean dust generated in the detection box.

The utility model discloses a pitching drilling type rescue drilling machine. Comprising a crawler chassis, a front supporting frame arranged at the front end of the crawler chassis in a pitching mode, and a pitching adjusting assembly arranged on the crawler chassis, connected with the first end of the front supporting frame and used for adjusting the pitching angle of the front supporting frame relative to the crawler chassis. The front supporting assembly is arranged at the second end of the front supporting frame in a telescopic and rotary mode and used for supporting the front supporting frame, the drilling assembly is arranged on the front supporting frame, and the rear supporting frame is arranged at the rear end of the crawler chassis. Compared with the prior art, the rescue drilling machine has the advantages that the terrain adaptability of the rescue drilling machine is improved, meanwhile, the stability of drilling work is improved, the roadway penetrating precision is guaranteed, practicability is high, and the rescue drilling machine is suitable for popularization and application. The method is suitable for wide popularization and application.

The invention provides refrigeration equipment which comprises a box body, a drawer slidably connected into the box body in the front-back direction and a sliding rail assembly arranged between the box body and the drawer and further comprises an auxiliary supporting mechanism connected to the box body. The auxiliary supporting mechanism provides upward supporting force for the drawer, so that the load borne by the sliding rail assembly is reduced, the requirement of a user for the large-volume refrigeration equipment is met on the premise that the sliding rail assembly is not replaced, the manufacturing cost of the large-volume refrigeration equipment is reduced, and the service life of the large-volume refrigeration equipment is prolonged. And the problems that the sliding rail deforms in the using process, and the quality of the refrigeration equipment is affected are solved.

The large-load fastener capable of being automatically locked comprises a frame, installation rods are symmetrically arranged between the two sides of the frame, and installation rings are installed on the outer sides of the installation rods. Adjusting mechanisms are symmetrically arranged between the frames, and supporting mechanisms are arranged at the top ends of the frames. Wherein the adjusting mechanism comprises a two-way screw which is in threaded connection with the interior of the frame, limiting rods are symmetrically and fixedly connected to one end of the frame, one ends of the limiting rods penetrate through the frame to be in sliding connection, fixing plates are symmetrically installed on the corresponding sides of the frame, and fixing boxes are obliquely and symmetrically installed in the fixing plates; through the resetting performance of the first telescopic spring, the tooth block is in meshed connection with the spiral teeth on the outer side of the two-way screw rod, so that the adjusted two-way screw rod can be fixed and limited, the situation that the column formwork shakes due to external force factors can be effectively avoided, then the extra load borne by the frame is reduced, and the fixing effect of the column formwork is improved.
