Detailed Description
As shown in fig. 1-2, an outdoor swimming color-changing lifesaving floating ball capable of measuring the temperature of a water area is an air bag with a lifesaving function and provided with an inflation inlet 1; a water temperature meter 10 is arranged at the position where the floating ball is contacted with water; the water temperature meter is connected with the alarm circuit; when the water temperature measured by the water temperature meter is lower than the threshold value, the alarm circuit 7 sends out alarm information.
The water temperature meter is arranged at the lower part of the floating ball; the weight of the lower part of the floating ball is larger than that of the upper part of the floating ball, so that the lower part of the floating ball is contacted with water when the floating ball is positioned in the water.
The ball wall 2 at the upper part of the floating ball is coated with visual sensitive striking color paint, and the ball wall 3 at the lower part of the floating ball is molded by light guide material or transparent material.
When the water temperature measured by the water temperature meter is lower than the threshold value, the alarm circuit sends out light warning information by an indicator lamp in the alarm circuit.
The indicator lamps comprise a red indicator lamp 4 and a green indicator lamp 8; the on-off states of the red indicator light and the green indicator light are mutually exclusive; the change-over switch of the red indicator light and the green indicator light is controlled by the electromagnet.
The temperature sensing part 9 of the water temperature meter is in a non-sharp shape, and a thermistor 5 with a waterproof structure is arranged at the temperature sensing part; when the floating ball is placed in water, the thermistor is in contact with the water.
The thermistor is arranged on a power supply loop of the electromagnet; when the resistance value of the thermistor changes due to temperature change, the current passing through the electromagnet changes, so that the attraction force of the electromagnet changes to switch the on-off state of the red indicator light and the green indicator light.
The floating ball is formed by environment-friendly super-thick PVC materials which are not easy to puncture; the water thermometer is a water thermometer capable of reading a water temperature value; and a switch 6 is arranged at the alarm circuit 7.
