The invention discloses an automatic cleaning method and device for movable escalator steps. The automatic cleaning method includes the steps that static images of the escalator steps are obtained through an imaging unit and transmitted to a control unit; the control unit compares the static images with pre-stored standard images to judge the pollution grades of the escalator steps and then determine the cleaning intensity in a spraying unit; and based on the cleaning intensity, the escalator steps are cleaned through the spraying unit. By means of the automatic cleaning method and device, the escalator steps can be cleaned in place, the cleaning efficiency is greatly improved, the water consumption of escalator step cleaning is reduced, and negative influences of drained waste water on the environment are avoided.

The invention relates to a novel composite surface-enhanced spiral bevel gear production process system based on a current anti-fatigue manufacturing method system and integrating induction quenching and gas nitriding. The invention aims to provide a composite surface-enhanced cyclo-palloid spiral bevel gear manufacturing method with heated precision of 4 to 6 levels and achieving the purpose that the theory contact zone meshed strength is meshed with carburizing and quenching strength. The invention aims to further provide a new spiral bevel gear production technology which can not only embody the current anti-fatigue high-end gear manufacturing method purpose, but also agree with the complete software and hardware match of a roadmap of heat treatment technology development in China.

The invention provides a washing method for a washing machine. The washing machine comprises an internal tub, a motor, a draining valve and a main controller; and the washing method is characterized by comprising the following steps: (1) normally washing; (2) rinsing for a plurality of times; (3) completing the rinsing, starting the draining valve to access a draining state, wherein the delay starting time of the motor is T1; (4) electrifying the motor to drive the internal tub to rotate, wherein the rotary cleaning time is T2; (5) after completing once rotary cleaning, interrupting the power supply of the motor to drive the internal tub to rotate under inertia, wherein the rotating time under inertia is T3; (6) determining whether the circular cleaning time N of the internal tub reaches a preset value, if so, entering the next step, if not, returning to step (4); (7) electrifying the motor to enter a dewatering program, wherein the dewatering time is T4; (8) stopping the motor to complete the dewatering, and judging whether the rinsing at the time is the last rinsing, if so, entering the next step, if not, returning to step (2); and (9) drying in the air. According to the washing method, the tub is cleaned following the rinsing at each time, thus, the washing tub is repeatedly cleaned for a plurality of times, and the washing tub can be ensured to be cleaned efficiently.

The invention discloses a cleaning device with maintenance and dust removal functions for furniture. The cleaning device comprises a table plate, wherein a table plate supporting sliding rod is movably connected with a side wall of the table plate; a sliding rod groove is formed in the surface of the table plate supporting sliding rod; one side of the table plate supporting sliding rod is fixedlyconnected with one end of a fixed pipe; an inner wall of the fixed pipe is movably connected with the surface of a retractable sleeve; the inner wall of the retractable sleeve is fixedly connected with one end of a spring; one side of the spring is fixedly connected with the inner wall of the retractable sleeve. When a fan rotates, dust under a table is sucked into a filtering cover which is fixedly connected with the inner part of a dust storage box; a first motor drives a cam to rotate so that a cleaning agent plastic box, which is fixedly connected between an ejection rod and a fixed rod, is squeezed and a cleaning agent flows into a rotary rod through a discharging pipe; a second motor drives the rotary rod to rotate, and a hairbrush which is fixedly connected onto the rotary rod is used for cleaning and maintaining the bottom of the table plate, so that people can clean dirt and the dust under the table, without the need of squatting down.

The invention relates to a cleaning device, in particular to a cleaning device for edible pupae. The technical problem of the present invention is to provide an edible pupa cleaning device with thorough cleaning, proper cleaning force and simple operation. The technical solution of the present invention is: an edible pupa cleaning equipment, including a base, a first support, a second support, a third support, a first fixing plate, a first bearing seat, a second fixing plate, a second bearing seat, The first rotating shaft, etc.; the first bracket is fixedly connected to the upper left side of the base, the second bracket is fixedly connected to the upper right side of the base, a through hole is opened on the second bracket, and the tops of the first bracket and the second bracket are fixed. A third bracket is connected, and a guide hole is opened on the right side of the third bracket. The invention achieves the function of cleaning edible pupae, not only realizes the filtration of water, but also realizes the function of replacing manual cleaning. The invention has the characteristics of simple operation, proper cleaning, and appropriate cleaning force.

Provided is a washing method of a roller washing machine. The washing method comprises the steps of 1), washing; 2), rinsing; 3), turning on a draining pump, detecting whether or not the water level is lower than H1, if yes, executing the next step, otherwise executing step 3) again; 4), keeping the rotating speed at V1 for T1; 5), judging whether or not the load distribution is uniform, if yes, conducing pre-dewatering, otherwise executing step 4); 6), finishing pre-dewatering; 7), keeping the rotating speed at V1 for T1; 8), judging whether or not the load distribution is uniform, if yes, executing the next step, otherwise executing step 7); 9), keeping the rotating speed at V2 for T2, and then reaching V3; 10), detecting whether or not the water level is lower than H1, if yes, turning off the draining pump, otherwise executing step 9); 11), turning on an inlet valve; 12), judging whether or not the total water inlet time is greater than T4, if yes, executing step 15), otherwise executing the next step; 13), detecting whether or not the water level is higher than H2, if yes, executing the next step, otherwise executing step 12); 14), judging whether or not T5 is finished, if yes,executing the next step, otherwise executing step 14) again; 15), turning off the inlet valve, judging whether or not the delayed turn-on time reaches T6, if yes, turning on the draining pump, otherwise executing step 15) again; 16), judging whether or not the time of duration reaches T3, if yes, executing the next step, otherwise executing step 16) again; 17), judging whether or not the rinsingis the last time of rinsing, if yes, executing the next step, otherwise executing step 2); 18), completing the washing. The washing method can achieve double washing and save energy and has high efficiency, a high-speed washing water ring is formed, the decontamination and cleaning ability is stronger, and secondary pollution is avoided.
