Embodiment Construction
[0018] The overall appearance of the robot is as figure 1 As shown, the internal structure is as figure 2 As shown, it is mainly composed of four parts: a robot power mechanism (1), a water polo gathering mechanism (2), a water polo transport mechanism (3), and a water polo collection mechanism (4).
[0019] The power mechanism of this robot is as image 3 shown. The main shaft of the DC motor (5) is fixedly connected with the impeller (6), and the impeller (6) rotates in the water under the drive of the DC motor (5), forming a stream of water along the water inlet direction. Steering nozzle (7) is positioned at the back of impeller (6), and water flow is ejected by steering nozzle (7). Its smaller cross-section can generate greater water pressure, and the robot has greater power.
[0020] When the robot power mechanism (1) starts, the water flow flows from the head of the body to the tail of the body, which provides propulsion for the movement of the body, and also prov...

The invention discloses a water polo ball automatic collection robot. The water polo ball automatic collection robot comprises a robot power mechanism, a water polo ball gathering mechanism, a water polo ball conveying mechanism, and a water polo ball collecting mechanism. Water jet propulsion is adopted by the robot power mechanism, and impeller rotation is power. With water flows produced by therobot power mechanism, the water polo ball gathering mechanism enables the floating water polo balls outside a device to gather to the front of the robot, and under the action of pulleys on two sidesof the entrance of a machine body, the water polo balls are positioned and enter the machine body. The water polo ball conveying mechanism, through driving a conveying element to reciprocate, enablesthe water polo balls in the machine body to enter the water polo ball collecting mechanism at equal intervals. The water polo ball collecting mechanism is composed of a ratchet bar launching mechanism, a cam plate overturning mechanism, and a water polo ball adjusting and container lifting mechanism. The ratchet bar launching mechanism launches the water polo balls at intervals. The water polo balls, after colliding with the cam plate overturning mechanism, enter detachable and replaceable ball collection containers on two sides regularly. The water polo ball automatic collection robot has capacities of catching the water polo balls rapidly, efficiently conveying the water polio balls and storing large amounts of the water polo balls.
Description
technical field [0001] The invention is a robot used in water environment to automatically recover water polo, which belongs to the field of robot structure design. Background technique [0002] As an official event of the Olympic Games, water polo has a certain degree of popularity. However, due to the particularity of the working environment on the water, large-scale manual salvage of water polo is relatively difficult. The present invention aims to replace manual labor and perform fully automatic salvage and recovery of water polo, which greatly saves labor costs and time costs, and improves the efficiency of water polo training and water polo sports. Contents of the invention [0003] The present invention comprehensively considers the influence of special factors such as water buoyancy and water flow resistance, and has higher efficiency than manual recovery. Using a variety of mechanisms, it has the ability to quickly capture water polo, efficiently transport and s...
