The first pipe 11 positioned below is formed in such a manner that a plurality of first holes 14 are arranged in the longitudinal direction while being spaced apart from each other. A plurality of first graduations 16 are formed on the outer surface of the first pipe 11 between the plurality of first holes 14. The lower end of the first pipe 11 is screwed to the fixture 20 having a wedge shape to close the lower end of the first pipe (11).

The upper end of the first pipe 11 is closed by the first closure 34, a pair of first electrodes 29 are fixed to the lower end of the first closure 34, and the pair of first electrodes Reference numeral 29 is connected to the first alarm means through a power line extending to the outside.

Therefore, when the first pipe 11 is buried in a river or a wet flooded area at a predetermined depth, the water level is increased and water is introduced into the first pipe 11 through the first hole 14. When the buoyancy body 21 is moved upward in the first pipe 11 and continuously rises to a level exceeding a predetermined height, the first contact plate 25 finally moves the pair of first electrodes ( 29), the power is applied to the first alarm means to alert the user to an increase in the water level.

In other words, when the user fixes the first pipe 11 to the ground and installs it, the scale to which the alarm is desired is exposed to the surface or the surface of the water. When the water is increased, water is introduced into the pipe through the first hole 14 drilled on the outer surface of the first pipe 11 to gradually float the first buoyancy body 21 to a height that matches the external water surface. At this time, even if the float floating in the water with the rise of the water level obscures part of the first hole 14, the increased inflow of the water through the upper and lower adjacent holes is possible, so that the first buoyancy body 21 It will not affect the injury.

The lower end of the second pipe 12 is screwed to the upper end of the first pipe 11. A plurality of second scales 17 are formed on an outer surface of the second pipe 12, in which a first collecting hopper 36 is slidably movable in the vertical direction, and an upper end portion of the second pipe 12 is provided. One second hole 15 is formed in the portion adjacent to the second hole 15. At the inner lower end of the second pipe 12, a mandrel 33 is seated on an upper surface of the first closure 34, and a second buoyancy body 22 having an annular shape is fitted to the mandrel 33. When the second buoyancy body 22 is introduced into the second pipe 11 through the one second hole 15, the second buoyancy body 22 is upward in the second pipe 12 according to the height of the water introduced therein. Is moved. The second contact plate 26 is fixed to the upper end of the second buoyancy body 22 so that it can be integrated with the second buoyancy body 22.

In this case, a connection terminal 51 for grounding the first and second electrodes 11 and 12 so that the first and second electrodes 29 and 30 may be connected to each other may be connected to each other. It would be desirable to provide such that the first and second warning means can be shared in one device.

Between the inner surface of the first neck portion 38 and the outer surface of the second pipe 12, a lower end portion of the first collecting hopper 36, which is slidably inserted up and down on the outer surface of the second pipe 12. And a first packing 42 is fitted to perform a sealing function. A screw portion is formed on an outer surface of the first neck portion 38, and the first funnel member 40 is screwed to the screw portion so that the first neck portion 38 is pressed against the outer surface of the second pipe 12. Let's go. Small holes 44 are formed on the bottom surface of the first collecting hopper 36, and preferably, two or more holes are drilled in different sizes within the same radius from the center to set different amounts of drainage per hour. To the edge of the first funnel member 40, which is dedicated to the bottom surface of the first catching hopper 36, the rainwater in the hopper 36 is discharged to the outside when coinciding with the small hole 44. The notch 46 is formed to be able to. A constant lighting lamp 48 is provided at the upper end of the second pipe 12 to maintain a constant lighting state.

That is, when the first funnel member 40 is set in accordance with the appropriate scale on the second pipe 12 in consideration of the rainfall of the danger level, the average rainfall of the region is collected by the funnel member, and the scale is set by increasing the rainfall. Increasing the risk level is added to the inside of the second pipe (12) through the second hole (15), and then the second buoyancy body 22 is the second pipe ( 12 is moved upwardly along the mandrel 33 and the second contact plate 26 is connected to the pair of second electrodes 30 while power is applied to the second alarm means to prevent rain on the user. You will be alerted to dangerous increases. At this time, by rotating the funnel member 40 to maintain the small hole 44 and the notch 46 in communication with each other, the water collected in the first collecting hopper 36 is the small hole 44 And it is discharged to the outside little by little through the notch portion 46, so that the alarm does not ring unless there is a sudden increase in rainfall over a certain time period.

This takes into account the effect of rainfall per hour on the surface. Even if the same amount of rainfall falls in a short time, most of the rainwater flows down the surface, which acts as a risk factor. This is because the amount of rainfall falls into the basement sufficiently and flows very little along the surface of the earth, which does not significantly affect the level rise.
