Description
Art
The utility model relates to a kind of protecting device for water pump, specifically a kind of submersible pump water-shortage protection device.
Background technique
Submersible pump is placed in water and works, and when drainage works, time as anhydrous in water source place, water pump can lack of water dally, and not only wastes electricity, and large without the heating of water for cooling submersible pump, greatly affects the life-span of water pump.
Summary of the invention
The purpose of this utility model is to provide a kind of submersible pump water-shortage protection device, in water-stressed conditions, automatically closes submersible pump.
The technical solution adopted in the utility model: this submersible pump water-shortage protection device comprises submersible pump handle, pressure bladder lid, Buoyancy bar, rubber cable, pressure bladder and sensitive switch; Described submersible pump handle there are hinging hole and boss; Described Buoyancy bar is hinged on submersible pump handle by pan, and it has through hole; Described pressure bladder is placed in the through hole one end on Buoyancy bar, and is placed between Buoyancy bar and pressure bladder lid, and by Buoyancy bar and pressure bladder lid compression fit, pressure bladder faces the boss on submersible pump handle; Described pressure bladder lid is connected on Buoyancy bar, porose on it; Described rubber cable is connected in the through hole the other end on Buoyancy bar, and rubber cable seals up the through hole on Buoyancy bar, and the electric wire in rubber cable is connected with the normally-closed contact of sensitive switch; Sensitive switch is connected in the through hole on Buoyancy bar, and the actuation button of sensitive switch faces pressure bladder.
The beneficial effects of the utility model: in water-stressed conditions, automatic closing water pump.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is the overall structure schematic diagram of a kind of submersible pump water-shortage protection device of the utility model.
Embodiment
Fig. 1 represents the overall structure schematic diagram of a kind of submersible pump water-shortage protection device of the utility model.Known by figure, this submersible pump water-shortage protection device comprises submersible pump handle 1, pressure bladder lid 3, Buoyancy bar 5, rubber cable 7, pressure bladder 10 and sensitive switch 9; Described submersible pump handle 1 there are hinging hole 4 and boss 11; Described Buoyancy bar 5 is hinged on submersible pump handle 1 by pan 4, it has through hole 6; Described pressure bladder 10 is placed in through hole 6 one end on Buoyancy bar 5, and is placed between Buoyancy bar 5 and pressure bladder lid 3, and by Buoyancy bar 5 and pressure bladder lid 3 compression fit, pressure bladder 10 faces the boss 11 on submersible pump handle 1; Described pressure bladder lid 3 is connected on Buoyancy bar 5, on it porose 2; Described rubber cable 7 is connected in through hole 6 the other end on Buoyancy bar 5, and rubber cable 7 seals up the through hole 6 on Buoyancy bar 5, and the electric wire 8 in rubber cable 7 is connected with the normally-closed contact of sensitive switch 9; Sensitive switch 9 is connected in the through hole 6 on Buoyancy bar 5, and the actuation button of sensitive switch 9 faces pressure bladder 10.
When the utility model is installed, the electric wire 8 in rubber cable 7 is connected on the ground the power line of submersible pump, the break-make of sensitive switch normally-closed contact is made to control the break-make of submersible pump power supply, it is work like this: be placed in by submersible pump in water source, plug electricity, if water is enough, Buoyancy bar 5 can float on the surface, and does not conflict with the boss 11 on submersible pump handle 1, the normally-closed contact of sensitive switch 9 closes, and water pump is energized; When lack of water in water source, Buoyancy bar 5 can be conflicted with the boss 11 on submersible pump handle 1, and the normally-closed contact of sensitive switch 9 disconnects, Pump Failure.
In addition to the implementation, the present invention also has other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop in the protection domain of application claims.
