Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the following detailed description will be provided with reference to specific embodiments.
As shown in fig. 1 and 2, an embodiment of the present invention provides an anti-freezing drainage device for an outdoor water pipeline, which includes a drainage pipe 51, an electrically controlled three-way valve, a temperature sensing switch 31, and a power source 61, wherein the left end of the electrically controlled three-way valve is connected to a water supply pipeline 11, the right end of the electrically controlled three-way valve is connected to a water pipeline 21, and the lower end of the electrically controlled three-way valve is connected to the upper end of the drainage pipe 51; the temperature sensing switch is arranged on the outer wall of the water supply pipeline; the power supply is electrically connected with the electrically-controlled three-way valve, and the temperature sensing switch 31 is arranged on a circuit between the power supply and the electrically-controlled three-way valve; the electrically controlled three-way valve has a first position at which the water supply line 11 communicates with the water usage line 21, and a second position at which the water usage line 21 communicates with the water discharge line 51; the water supply pipeline and the water using pipeline are both positioned above the water discharging pipe.

Further, the power source 61 is a storage battery, so that the electrically controlled three-way valve is powered by the storage battery. It may be preferred that the power supply is a 24V power supply.
Specifically, the power supply further comprises a solar power supply device for charging the storage battery, so that the storage battery is charged by the solar power supply device, the power shortage of the storage battery is avoided, and the drainage device can work normally. Preferably, the storage battery is a lithium ion storage battery pack, the solar power supply device comprises a solar panel and a charge controller, and the solar panel is electrically connected with the lithium ion storage battery pack through the charge controller.
Preferably, the temperature sensing switch 31 is located at one end of the water supply line close to the electrically controlled three-way valve.
Further, the temperature sensing switch 31 is a normally open switch. At the moment, when the temperature sensing switch detects that the temperature of the water supply pipeline is higher than a first set temperature, the temperature sensing switch is in an open state, the electric control three-way valve is in a first position, and the water supply pipeline is communicated with the water using pipeline; in cold weather, when the temperature inductive switch detects that the temperature of the water supply pipeline is lower than a second set temperature, the temperature inductive switch is in a closed state, the electric control three-way valve is in a second position, the water using pipeline is communicated with the drain pipe, and water in the water using pipeline is discharged through the drain pipe.
