Description

Technical Field

[0001] The utility model relates to the field of fluids, in particular to a water tank water replenishment control device used in areas with unstable tap water supply. Background Art

[0002] In some places abroad, municipal tap water supply is unstable, and the tap water pressure is insufficient to meet daily water needs. Residents have installed water tanks on their roofs, using pumps to pump the irregularly low-pressure water from municipal pipelines to the rooftop tanks for storage to solve their daily water needs. For a long time, this method of supplying water to rooftop tanks required manual operation, which was extremely inconvenient.

[0003] The water tank replenishing device in the prior art is implemented by using a high liquid level sensor and a low liquid level sensor. The low liquid level sensor starts the water pump when it detects that there is no water. If this method is used, the water pump may be damaged by idling due to the lack of water in the tap water pipeline. Utility Model Content

[0004] The utility model aims to provide a water tank water replenishment control device for an area with unstable tap water supply, which can automatically start a water pump when the water tank is short of water and there is water in the tap water pipeline.

[0005] To achieve the above-mentioned objectives, the utility model provides a water tank water replenishment control device for areas with unstable tap water supply, including a controller for controlling the start and stop of a water pump, a high liquid level sensor and a low liquid level sensor connected to the controller for detecting the water level in the water tank, and also including a water inlet pipe liquid level sensor for detecting whether there is water in the tap water pipeline, which is connected to the controller.

[0006] In one embodiment of the present invention, a middle liquid level sensor for detecting the water level in the middle of the water tank is further included, and the middle liquid level sensor is connected to the controller.

[0007] In one embodiment of the present invention, the high liquid level sensor, the low liquid level sensor, and the medium liquid level sensor are connected to a first transmitting antenna, the water inlet pipe liquid level sensor is connected to a second transmitting antenna, and the controller is connected to a receiving antenna for receiving the first transmitting antenna and the second transmitting antenna.

[0008] In one embodiment of the present invention, the water inlet pipe liquid level sensor, the high liquid level sensor, and the low liquid level sensor are contact liquid level sensors or non-contact liquid level sensors.

[0009] In one embodiment of the present invention, the controller is connected to a relay, and the relay is used to connect to the water pump.

[0010] In one embodiment of the present invention, the controller includes a main timing module, a storage module, a water pump voltage sensor, and a water pump current sensor connected to the main control unit. When the water pump is rusted or foreign matter enters the pump, causing a stall, the current at the start of the water pump is abnormal, and the controller controls the water pump to power off. When the water pump current is abnormal, the controller controls the water pump to power off to prevent the water pump from burning out. When the water pump has not been started for a long time, the main control unit controls the water pump to start to prevent rust. When the time from the last start reaches the first set length (such as 24 hours), the water pump is controlled to start for the second set length (such as 20 seconds).

[0011] In one embodiment of the present invention, the controller further comprises an audible alarm device and / or an optical alarm device connected to the main control unit. When the controller is under-voltage, current abnormal, or voltage abnormal, the audible alarm device and / or optical alarm device sounds an alarm to alert the user.

[0012] In one embodiment of the present invention, the water inlet pipe or the water outlet pipe of the water pump is equipped with a check valve, and the controller further includes a high liquid level indicator, a medium liquid level indicator, a low liquid level indicator, and a water inlet pipe water indicator connected to the main control unit. The user can determine the water level information of the water inlet pipe and the water tank by the various indicators.

[0013] In one embodiment of the present invention, the first transmitting antenna and the second transmitting antenna respectively include a sub-control unit, a power supply battery, a battery voltage sensor electrically connected to the sub-control unit, a sub-timing module, and an antenna body. The sub-control unit can send liquid level information and battery voltage information according to a set period to extend the service life of the power supply battery.

[0014] In one embodiment of the present invention, the controller further includes a water pump current abnormality indicator light, a water pump voltage abnormality indicator light, a first low battery indicator light, and a second low battery indicator light connected to the main control unit.

[0015] In this utility model, a low liquid level sensor and a water inlet pipe liquid level sensor are set. When there is water in the water inlet pipe and the water tank is short of water, the controller controls the water pump to start replenishing water until the high liquid level sensor detects water. When the water inlet pipe liquid level sensor detects no water, the controller controls the water pump to power off. BRIEF DESCRIPTION OF THE DRAWINGS
