Embodiment Construction
[0006] The invention consists of a straight tube (1), a magnetic float (2), a reed switch (3), a micro switch (4), a button switch (5), a relay (6), a solid state relay (7), and a power supply device. (8), water irrigation (9) and water pump (10) form. The connecting straight pipe (1) communicates with the water irrigation (9) to form a connector structure, and the upper ends of the connecting straight pipe (1) and the water irrigation (9) communicate with the atmosphere. The magnetic float (2) can move up and down with the change of water level in the connecting straight pipe (1). The coil J of the relay (6) is connected in parallel with the DC end of the solid state relay (7), and the switch J1 of the reed switch (3), the button switch (5) and the relay (6) are connected in parallel; the power supply (8), the coil J of the relay, and the relay Switch J1 and micro switch (4) are connected in series. The reed switch (3) is installed outside the tube connected to the lower en...

The invention relates to an electromechanical fully-automatic water pumping control device. The electromechanical fully-automatic water pumping control device consists of a communicating straight pipe (1), a magnetic float (2), a reed switch (3), a microswitch (4), a button switch (5), a relay (6), a solid relay (7), a power supply device (8), a water tank (9) and a water pump (10), wherein the magnetic float (2) can move up and down with a water level in the communicating straight pipe (1); a coil of the relay is connected with a direct current end of the solid relay in parallel, and the reed switch, the button switch and a switch of the relay are connected in parallel; the power supply device, the coil of the relay, the switch of the relay and the microswitch are connected in series. Normally, a power supply switch K is closed. When the water level of the water tank is lowered, the float falls to the part of the reed switch, and the reed switch is communicated to begin pumping water. When the water lever is raised and the float is in contact with the microswitch, the microswitch is turned off, and water pumping is stopped.
Description
[0001] The invention relates to an automatic water pumping control device, which belongs to the fields of sensing technology, electronics and machinery. The device can be applied to water pumping control in construction sites, individual families and schools. Background technique [0002] Manual pumping is often used in places where there is no running water, such as construction sites with inconvenient running water, individual families, and mountainous schools. Manual pumping often has the following problems: one is that it requires personnel wages, and the other is that manual pumping often forgets to pump water due to responsibility or busy work. Forget to turn off the water pump, resulting in water cut-off or waste of water and electricity. The invention designs a simple pumping control device to solve the problems caused by manual pumping. Contents of the invention [0003] The purpose of the invention is to design a simple structure and low-cost pumping automatic cont...
