Description

Technical Field

[0001] The utility model relates to the technical field of water lifesaving equipment, in particular to an autonomous tracking triangle robot for water lifesaving. Background Art

[0002] Water rescue is an important measure to ensure the safety of people in water activities. With the popularity of water sports, more and more people are beginning to come into contact with water, and water rescue is becoming more and more important. At present, water rescue mainly relies on two methods: artificial swimming rescue and yacht rescue. Artificial swimming lifesaving requires lifeguards to have swimming skills and rescue experience, but this method has the risk of drowning, limited manpower, and cannot cope with large-scale rescue operations. At the same time, artificial swimming lifesaving also requires witnesses who can swim to call the police in time, and the time requirement is high. Although yacht lifesaving has high rescue efficiency, it has high requirements for water areas and relatively high costs, and cannot be widely used in various waters. Utility Model Content

[0003] The utility model aims to provide an autonomous tracking triangle robot for water rescue, which is small and light, easy to carry, low in cost, widely used in various waters, and can quickly replace manual water rescue.

[0004] The above technical objectives of the utility model are achieved through the following technical solutions:

[0005] An autonomous tracking triangular robot for water lifesaving comprises a triangular hollow shell, three sides of the triangular hollow shell are connected to hand grab bars, a gap is left between each hand grab bar and the outer wall of the triangular hollow shell, two oppositely arranged drive motors are installed at the lower end of the triangular hollow shell, the power output shaft of each drive motor is connected to a drive turbine, the upper end of the triangular hollow shell is rotatably connected to a camera, the lower end of the camera is connected to a rotating sleeve that extends into the triangular hollow shell and is rotatably connected thereto, a telescopic motor is upwardly installed in the triangular hollow shell, the telescopic shaft of the telescopic motor extends into the rotating sleeve, the side wall of the rotating sleeve is provided with a spiral groove that rises in a spiral shape, the free end of the telescopic shaft of the telescopic motor is provided with a sliding shaft that is slidably connected to the spiral groove, a battery and an integrated circuit board are arranged in the triangular hollow shell, a wireless remote control module is arranged on the integrated circuit board, and each drive motor and the telescopic motor are electrically connected to the integrated circuit board.

[0006] By adopting the above technical solution, when the delta robot moves on the water surface, it moves forward by two driving turbines, and turns by adjusting the rotation speed of the two driving turbines. By controlling the extension and retraction of the telescopic motor, the sliding shaft slides up and down in the spiral slide groove to drive the rotating sleeve to drive the camera to rotate, thereby searching for drowning people on the water surface. After the drowning person is found, the delta robot is controlled to track the drowning person autonomously. The drowning person can hold the grab bar with his hand, and the delta robot can drag the drowning person back to the shore.

[0007] The utility model is further configured as follows: a T-shaped rotating shaft is downwardly arranged at the lower end of the triangular hollow shell, the T-shaped rotating shaft is rotatably connected to a rotating disk, two motors are installed at the lower end of the rotating disk, a plurality of limiting protrusions are arranged at the upper end of the rotating disk, and a plurality of limiting slots corresponding to the limiting protrusions are opened at the lower end of the triangular hollow shell.

[0008] By adopting the above technical solution, when dragging a drowning person, if the hand gripping rod grabbed by the drowning person is not on the side opposite to the forward direction, the torque generated during the forward movement drives the rotating disk to rotate, so that the limiting protrusion is disengaged from the original limiting slot, until it rotates to the rear of the hand gripping rod in the forward direction, and the limiting protrusion is again engaged in the corresponding limiting slot, so as to prevent the rotating disk from rotating at will.

[0009] The utility model is further configured as follows: the lower end of the T-shaped rotating shaft is connected to two waterproof cables which are electrically connected to corresponding drive motors respectively, and the drive motor is powered and controlled by the waterproof cables.

[0010] The utility model is further configured as follows: one end of each driving motor is provided with a protective mesh cover with an outer cover corresponding to the driving turbine, and one end of each protective mesh cover away from the corresponding driving motor is open.

[0011] In summary, the utility model has the following beneficial effects:

[0012] First, the utility model adopts a triangular robot to replace manual search for drowning people on the water surface, and can also drag the drowning people back to the shore. It is small and light, easy to carry, low cost, and widely used in various waters;

[0013] Secondly, when dragging a drowning person, the utility model can automatically adjust the drowning person to the rear of the traveling direction, thereby reducing the traveling damping, and also enables the drowning person to better grasp the triangular robot.

The end of each protective mesh cover 32 away from the corresponding driving motor 3 is open, and the protective mesh cover 32 is used to prevent accidental injury to drowning people in the water. Three limiting protrusions 21 are provided at the upper end of the rotating disk 2, and three limiting grooves 13 corresponding to the limiting protrusions 21 are provided at the lower end of the triangular hollow shell 1 to prevent the rotating disk 2 from rotating freely relative to the triangular hollow shell 1.

A telescopic motor 5 is upwardly installed in the triangular hollow shell 1, and a telescopic shaft 51 of the telescopic motor 5 extends into the rotating sleeve 41. A spiral groove 42 that rises in a spiral shape is provided on the side wall of the rotating sleeve 41. A sliding shaft 52 that is slidably connected to the spiral groove 42 is provided at the free end of the telescopic shaft 51 of the telescopic motor 5.
