The following describes in detail the usage steps of an internet communication based drowning alarm in conjunction with fig. 1 to 3:
at the beginning, the alarm is fixedly installed on the shore, the suspension block 12 is suspended on the water surface, the floating plate 16 floats on the water surface, the sliding rod 14 is at the lower limit position, the ejection sliding block 29 is at the right limit position, the upper end of the first clamping block 33 is in the first clamping groove 31, the second spring 30 is in a compressed state, the baffle 36 is in a vertical state, the upper end of the second clamping block 39 is in the second clamping groove 37, and the upper end of the abutting rod 43 is in the opening 42.
When the water-saving device works, when drowning people appear in water, the drowning people struggle to generate water wave fluctuation, the floating plate 16 floating on the water surface continuously drives the slide rod 14 to slide up and down along with the fluctuated water wave, because the amplitude of the water wave fluctuation is larger than that of the general situation, the slide rod 14 can slide to the tooth socket 17 to be meshed with the ratchet cavity 18 when sliding upwards, the ratchet 20 drives the first rotating shaft 19 to rotate when the slide rod 14 slides upwards, when the first rotating shaft 19 slides downwards, the ratchet 20 does not drive the first rotating shaft 19 to rotate, and then continuously pushes the first gear 22 to rotate, the second gear 24 is driven to rotate through gear meshing, the second gear 24 plays a role in speed reduction, the accidental ejection starting caused by the large water wave fluctuation which happens occasionally is avoided, the second rotating shaft 23 and the winding wheel 25 rotate along with the second gear 24, then the winding wheel 25 continuously winds up the pull wire 53, and simultaneously, the first motor 26 drives the ejection cylinder 27 to turn to the position of a drowned person, the alarm 54 is started to send an alarm signal to prompt the position of the drowned person, the pull wire 53 pulls the first clamping block 33 downwards to enable the first clamping block 33 to be separated from the first clamping groove 31, and the ejection slide block 29 is ejected leftwards under the action of the second spring 30.
In the ejection process of the ejection slide block 29, when the ejection slide block 29 is about to slide to the left limit position, the second limit block 46 enters the opening 42 and pushes the abutting rod 43 to slide downwards, the abutting block 44 pushes the second clamping block 39 out of the second clamping groove 37, then the ejection slide block 29 collides and abuts against the first limit block 45 when sliding to the left limit position, the ejection slide block 29 stops sliding, the baffle plate 36 turns left rapidly, the self-inflating life buoy 48 is thrown into water under the action of inertia, the self-inflating life buoy 48 automatically inflates when contacting with water, after a drowning person grasps the self-inflating life buoy 48, the second motor 51 starts to drive the third rotating shaft 50 to wind the rope 52, and the drowning person is pulled back to the bank side to wait for rescue.
The invention has the beneficial effects that: the invention can automatically monitor the situation of the near-shore water surface, when drowning people appear, the drowning people continuously struggle to start the ejection device in the alarm, throw the life buoy to the drowning people and send out alarm signals, and draw the drowning people back to the shore to wait for rescue, thereby greatly shortening the waiting time for the drowning people to get the rescue and reducing the probability of accidents.
In the above manner, a person skilled in the art can make various changes depending on the operation mode within the scope of the present invention.
