An electric auxiliary power automatic water adding device

Abstract

The invention discloses an automatic water adding device with auxiliary electric power. The automatic water adding device is mainly formed by a support, a spring, a water bucket, a control circuit where a proximity switch is located, a water conveying module, an electromagnetic water valve and a hose. According to the situation that the specific gravity of a work water body is fixed, the constant level of the work water surface elevation can be maintained as long as the length change of the spring and the depth change of the water body in the hung water bucket are maintained to be identical, then, along with consumption of the water in the water bucket, the proximity switch is triggered when the water bucket ascends to the set height, the electromagnetic water valve is used for pouring water with the set volume into the container at a time through the water conveying module, the water bucket descends accordingly, and the work water surface elevation is continuously maintained to be unchanged. According to the automatic water adding device, the constant level of the water surface is achieved, and the division of an upper water level and a lower water level does not exist; furthermore, the water with the quantification volume is added at a time through the water conveying module, it is avoided that the circuit of the device is frequently closed and opened at the set water surface elevation, and the fault rate of the circuit is greatly reduced.

Description

technical field [0001] The invention relates to an automatic water adding device with auxiliary power, in particular to an automatic water adding device with electric auxiliary power to keep the water level constant. Background technique [0002] Known electric auxiliary power automatic water adding devices generally have the either-or problem of upper and lower water levels and frequent switching circuits: for example, the device shown in the authorized announcement number CN 100514239c, although it avoids the high failure rate caused by frequent switching of the circuit , but because it has upper and lower water levels, it cannot be regarded as a constant water adding device in the strict sense. For example, the device shown in the authorized announcement number CN101566387 can keep the water level basically constant, but it is at the cost of a high failure rate of the circuit; in addition, Some do not have auxiliary power unit, as shown in publication number cn94108500, t...

[0002] Known electric auxiliary power automatic water adding devices generally have the either-or problem of upper and lower water levels and frequent switching circuits: for example, the device shown in the authorized announcement number CN 100514239c, although it avoids the high failure rate caused by frequent switching of the circuit , but because it has upper and lower water levels, it cannot be regarded as a constant water adding device in the strict sense. For example, the device shown in the authorized announcement number CN101566387 can keep the water level basically constant, but it is at the cost of a high failure rate of the circuit; in addition, Some have no auxiliary power unit, as shown in the publication number cn94108500, although the water level can be kept constant, but due to the limited amount of water in the bucket at one time, manual water replenishment is required in the middle, so it is not suitable for a large amount of water supply for a long time
