The utility model discloses a swimming pool cleaning robot capable of enhancing the water channel cleaning effect. The swimming pool cleaning robot comprises a robot body, a sealing cavity and a water pumping cavity. Wheels are arranged at the bottom of the machine body, and a rolling brush is arranged at the front end. A garbage inlet is formed in the bottom of the machine body; a cleaning opening is formed in the position, corresponding to the garbage inlet, of the bottom of the sealing cavity. A water pumping opening is formed in the top of the side wall of the sealing cavity; the water pumping opening and the side wall of the sealing cavity are integrated; the water pumping cavity is arranged in the machine body, and water pumping fan blades are arranged in the water pumping cavity; the water inlet end of the water pumping cavity communicates with the water pumping opening, and the water outlet end of the water pumping cavity communicates with the outside. According to the swimming pool cleaning robot, the water absorption capacity is enhanced, and the cleaning effect is good.

This application relates to a method, apparatus, computer device, and storage medium for determining collision probability. The method includes: determining the number of collision detection operations based on model parameters in a discretized three-dimensional model of the propeller; performing collision detection operations based on the number of detections and recording the number of collision events; and determining the collision probability of an object colliding with the propeller based on the number of collision events and the number of detections. This quantitatively assesses the probability of an object colliding with the propeller, thereby determining the probability of the object passing through the propeller. Using this probability provides data support for the analysis of the rejection characteristics of aircraft propellers and the design of aircraft propellers, enabling researchers to design aircraft more accurately. This is of great significance for improving the overall resistance of aircraft to foreign object impacts and engine ingestion capabilities, and enhancing aircraft flight safety.

This invention discloses a waste filtration and collection device for a swimming pool underwater cleaning robot, comprising: a shell with an inlet channel and an outlet channel; the inlet channel having a confluence channel and two suction channels; the two suction channels are located at the bottom of the shell and converge to the lower end of the confluence channel; the upper end of the confluence channel extends into the inner cavity of the shell and divides the inner cavity into front and rear waste compartments; the outlet channel has a drain channel and two filter channels; the drain channel is located at the top of the shell, with a water pump impeller installed at the drain outlet at the upper end of the drain channel, and its lower end confluences and connects to the upper ends of the two filter channels; the lower ends of the two filter channels are equipped with filter screens, which correspond to the inlets of the front and rear waste compartments respectively; both ends of the confluence channel are gradually expanding openings, with the upper end guiding the flow direction towards the front and rear filter screen areas respectively. This invention can effectively reduce the flow resistance of the entire channel, reduce the power consumption of the swimming pool cleaning robot, and thus extend the effective working time of the robot.
