Referring to fig. 1-3, an embodiment of the present utility model discloses an automatic warning device for an open drain cover, comprising:
the main body frame 1 is provided with a cavity 2 and a water flow channel 3, the water flow channel 3 is respectively communicated with a water inlet 4 above the main body frame 1 and a water outlet 5 below the main body frame 1, the water flow channel 3 is communicated with the cavity 2, and the cross section area of the water outlet 5 is smaller than that of the water inlet 4; the external water flow can enter the cavity 2 along the water inlet 4, and meanwhile, part of the water flow is discharged along the water outlet hole 5, and if the external water flow encounters flood, the water level in the cavity 2 is rapidly raised because the section radius of the water inlet 4 is far larger than that of the water outlet hole 5.
The lifting sleeve 6 is of a structure with inner layers and outer layers sleeved in sequence, the lifting sleeve 6 is arranged on the main body frame 1 in a penetrating mode, and the bottom end of the lifting sleeve 6 extends into the cavity 2; lifting of the lifting sleeve 6 within the main body frame 1 can be achieved.
The first compressible air bag 7 is positioned in the cavity 2, and the first compressible air bag 7 is connected with the bottom end of the lifting sleeve 6; the water flowing from the water flow channel 3 into the cavity 2 compresses the first compressible air bag 7 at the upper part of the cavity 2, and the lifting sleeve 6 is jacked up by the air pressure generated when the first compressible air bag 7 contracts.
The warning lamp 8 is positioned at the top end of the lifting sleeve 1; the warning lamp 8 can be jacked up along with the jacking of the lifting sleeve 6.
In this embodiment, the warning lamp 8 includes a bulb 81, a battery 82, a conductive post 83, a second compressible air bag 84 and a wire 85, the battery 82 is located at the lower end of the bulb 81, the lower end of the battery 82 is connected with the second compressible air bag 84, the conductive post 83 is provided with two sections which are respectively installed at the upper end and the lower end in the second compressible air bag 84, and the wire 83 is respectively connected with the lower end of the battery 82 and the conductive post 83 located at the lower end; the increased air pressure within the lift sleeve 6 also compresses the second compressible bladder 84, causing the conductive posts 83 within the second compressible bladder 84 to contact one another, forming a closed circuit, and the light bulb 81 to illuminate when the warning light 8 is raised.
In this embodiment, the water inlet 4 is funnel-shaped, the cross-sectional diameter of the water outlet 5 is 1/4 of the smallest cross-sectional diameter of the water inlet 4, and the water flows in at a higher speed than the water flows out, so that the water flow from the water flow channel 3 into the cavity 2 can be realized.
In this embodiment, the lifting sleeve 6 includes an outer sleeve 61, an intermediate sleeve 62 and an inner sleeve 63, the outer sleeve 61 is fixed with the main body frame 1, the bottom ends of the intermediate sleeve 62 and the inner sleeve 63 are provided with limiting blocks 64, the intermediate sleeve 62 and the inner sleeve 63 can extend upwards to realize lifting, and the lifting sleeve 6 can be jacked up by the air pressure generated when the first compressible air bag 7 contracts, so that the lifting sleeve 6 gradually rises to form a visible warning rod.
In this embodiment, warning lamp 8 is fixed on inboard sleeve 63 top, and warning lamp 8 follows inboard sleeve 63 and realizes going up and down, realizes reminding the pedestrian around, avoids the danger of falling.
The specific working mode is as follows: in operation, as shown in fig. 3, when the drain cover is opened, external water flows into the cavity 2 along the water inlet 4, and part of water flows are discharged along the water outlet 5. If flood occurs, when the external water flow is large, the water level in the hollow cavity 2 is rapidly raised due to the fact that the size of the water inlet 4 is far larger than that of the water outlet hole 5, the generated still water pressure can compress the first compressible air bag 7 at the upper part of the hollow cavity 2, and the air pressure generated when the first compressible air bag 7 is contracted can jack up the lifting sleeve 6, so that the lifting sleeve 6 is gradually raised to form a visible warning rod. At the same time, the air pressure raised in the lifting sleeve 6 also compresses the second compressible air bag 84, so that the conductive posts 83 inside the second compressible air bag 84 contact each other to form a closed circuit, and the bulb 81 is lighted, thereby reminding surrounding pedestrians of falling and avoiding the danger of falling. After the flood passes, the water flow in the cavity 2 is gradually discharged from the water outlet hole 5, the static water pressure disappears, the first compressible air bag 7 returns to the original position under the self elastic action, and the lifting sleeve 6 falls back into the wellhead under the action of gravity. At the same time, the second compression balloon 84 also springs back to its original position, creating an open circuit, extinguishing the bulb 81, conserving power for the next warning.
