The invention discloses an AGV obstacle avoidance path planning method in an unmanned warehousing system, and the method comprises the steps: employing nested Logistic mapping and Skew Tent mapping to generate a chaotic initialization population to replace a population generation mode of a conventional differential evolution algorithm, carrying out the Levy flight operation after the selection operation, and carrying out the global path search on an environment map, thereby achieving the optimal path planning. And obtaining an AGV global feasible path avoiding obstacles in the environment map, and when the AGV has an unknown obstacle on the feasible path, re-planning the local path by adopting a dynamic window method so as to enable the AGV to realize an obstacle avoidance process in an interval where the unknown obstacle is located. The improved differential evolution algorithm enhances the global search capability through chaos initialization and a Levy flight strategy, and the AGV can quickly respond to an unknown obstacle through a dynamic window rule. The adaptability and the accuracy of path planning are improved, and the obstacle avoidance capability and the safety of the AGV in a complex environment are enhanced at the same time.

This utility model discloses an adjustable brake integrated caster, relating to the field of integrated casters. The adjustable brake integrated caster includes a mounting base plate, a first fixing block, a connecting rod, an adjustment mechanism, and a reset mechanism. The adjustable brake integrated caster employs an adjustment mechanism located between the mounting base plate and the connecting rod. This adjustment mechanism facilitates adjustment of the contact tightness between the brake block and the directional wheel, allowing for easy transitions between braking and de-braking states. When the trolley is running down a steep slope, the worker pushing it can adjust the adjustment mechanism by observing the scale, enabling more effortless control of the trolley's stable operation on steep slopes. Simultaneously, the reset mechanism controls the reset of the connecting rod.

The application discloses a candle type liquid filtering device and belongs to the technical field of wastewater treatment. The candle type liquid filtering device comprises a barrel body, and a decontamination component is arranged on the inside and outside of the barrel body. The decontamination component comprises a first servo motor arranged on the upper side of a top cover. The output end of the first servo motor is fixedly connected with a lead screw. The outer side of the lead screw is threadedly connected with a lead screw nut. The outer side of the lead screw nut is sleeved with a movable disc. The residual residues and filter cakes on the surface of the ceramic filter core are scraped off in the process of downward movement of the scraping ring. Since the residual impurities on the surface of the ceramic filter core can be removed by the scraping ring in the process of downward movement of the movable disc, the residual filter cakes are effectively prevented from breeding bacteria, so that the liquid is prevented from being polluted when filtering the liquid subsequently. Meanwhile, the scraping ring can also treat the filter cakes on the surface of the ceramic filter core after repeated upward and downward movement, so that the service life and cleanness of the ceramic filter core are ensured.
