Detailed Description

The invention will be further described with reference to the following figures and examples:

example 1: a flood prevention alarm device for hydraulic engineering, which is shown in figures 1 to 6; a flood prevention alarm device for hydraulic engineering comprises a cylinder body 1, a floating plate 2 and an alarm 5.

Barrel 1 is cylindric inside and is cavity and upper end opening, 1 bottom surface of barrel is equipped with a plurality of apertures 10, aperture 10 can the separation floating garbage among the hydraulic engineering get into in the use in barrel 1 to influence the early warning function of this device.

1 bottom of barrel still is equipped with mounting bracket 11, mounting bracket 11 includes rectangle installation arm 22 and rectangle installation piece 7, rectangle installation arm 22 one end with 1 welded connection of barrel, the rectangle installation arm 22 other end with 7 welded connection of rectangle installation piece, still be equipped with three through-hole 8 in the rectangle installation piece 7 and be used for with the screw fixation barrel 1.

The side wall of the barrel body 1 is symmetrically provided with a pair of rectangular through holes 15 and a pair of rectangular protrusions 3 about the axis of the barrel body 1, and the alarm is vertically movable in the rectangular through holes 15.

The alarm 5 is a waterproof alarm with a transmitting end 23 and a receiving end 24, one side of the lower portion of the transmitting end 23 is further provided with a rectangular first limiting block 6, the other side of the lower portion of the transmitting end 23 is further provided with a threaded first cylindrical protrusion 13, and the first cylindrical protrusion 13 penetrates through the rectangular through hole 15 and is in threaded connection with a butterfly nut 9, and the transmitting end 23 is movably mounted in the rectangular through hole 15 in the side wall of the barrel 1.

One side wall of the lower part of the receiving end 24 is further provided with a rectangular second limiting block 20, the second limiting block 20 is consistent with the first limiting block 6 at the lower part of the transmitting end in structure, the other side wall of the lower part of the receiving end 24 is further provided with a threaded second cylindrical protrusion 19, the second cylindrical protrusion 19 is consistent with the first cylindrical protrusion 13 in structure, the second cylindrical protrusion 19 is also in threaded connection with a butterfly nut 9, and the receiving end 24 is movably arranged in the rectangular through hole 15 opposite to the transmitting end 23 on the side wall of the barrel body 1.

The transmitting end 23 and the receiving end 24 in the alarm can be adjusted to a required height by unscrewing the butterfly nut 9 on the outer side, and then the butterfly nut 9 is screwed down to fix the transmitting end 23 and the receiving end 24.
