Abstract
The utility model relates to a water level over-ranging alarm. The alarm has the technical proposal that: a float is arranged in an alarm shell body, the float is fixed with a connecting rod horizontally, the tail end of the connecting rod is moveably connected on the inner wall of the alarm shell body through a sliding shaft, a guide bar is connected right above the float vertically, a contact switch is disposed above the guide bar, and the contact switch is connected with a power supply jack of the alarm at the outside of the shell body. The power supply jack can be connected with an alarming horn and an alarm lamp. After the water level over-ranging alarm is arranged on the bottom part of a ship cabin, when water flows into the ship cabin, the water can enter the shell body through a water inlet, the float drives the guide bar to ascend under the buoyancy of water, so the upper end of the guide bar can touch the contact switch, thereby the alarming horn and the alarm lamp power supply can be put through to send out alarm signals to people, and shipwreck accidents can be reduced.
Description
One, technical field:
The utility model relates to a kind of alarm, especially for a kind of water level overload alarm device of rivers embankment.
Two, background technology:
In recent years, can not in time be it is found that because of river level changes, thereby be caused casualties and property loss.
Three, summary of the invention:
The utility model is exactly at the problems referred to above, water level overload alarm device is provided, its technical scheme is: be provided with float in the alarm housing, float adopts foamed plastic, float horizontal fixed connecting rod, the end of connecting rod is movably connected on the alarm inner walls by movable axis, is provided with contact switch at the vertical guide rod that connects directly over the float above guide rod, and contact switch is connected with the outer alarm supply hub of housing.Supply hub can link together with alarming horn, alarm lamp.
After water level overload alarm device is installed in embankment, when water level transfinites, water enters in the housing by water inlet, float drives guide rod and rises under the water buoyancy function, make the guide rod upper end touch contact switch, thereby connect alarming horn, alarm lamp power supply,, thereby reduce the generation of shipwreck accident to people's signal that gives the alarm.
Four, description of drawings:
Accompanying drawing is a structure diagram of the present utility model:
1. housings among the figure, 2. connecting rod, 3. movable axis, 4. supply hub, 5. electric shock switch, 6. guide rod, 7. water inlet, 8. float.
Five, embodiment:
With reference to accompanying drawing, be provided with float (8) in the alarm housing (1), float (8) adopts foamed plastic, float (8) horizontal fixed connecting rod (2), the end of connecting rod (2) is movably connected on alarm housing (1) inwall by movable axis (3), the vertical guide rod (6) that connects is provided with contact switch (5) in the top of guide rod (6) directly over float (8), and contact switch (5) is connected with housing (1) external power jack (4).Supply hub (4) can link together with alarming horn, alarm lamp.
After water level overload alarm device is installed in embankment, when water level transfinited, water entered in the housing (1) by water inlet (7), and float (8) drives guide rod (6) and rises under the water buoyancy function, make guide rod (6) upper end touch contact switch (5), thereby connect alarming horn, alarm lamp power supply.
