Durable low-cost automatic water level control switch

Abstract

The invention discloses a durable and low-cost automatic water level control switch. The water level control switch is arranged on a fixed plate. A hole is arranged in the middle of the fixed plate. A lifting part is fixed on the fixed plate. The upper part of the upper part is provided with a spring leaf, the lifting part includes a fixed cylinder and a lifting tube inside the fixed cylinder, the floating part includes a sealed bucket fixed under the bottom plate, a gravity floating body is arranged in the bucket, and a vertical connection is fixed on the gravity floating Rod, when the water level rises, the connecting rod drives the lifting tube to rise and the top plate touches the spring piece, and the switch is disconnected; when the water level drops, the upper pressure plate of the connecting rod presses down the spring piece, and the switch controls the operation of the water pump. Using this switch can reduce the cost of human resources, no need Waiting for water supply can reduce the cost of the water supply system and facilitate popular use.

Description

technical field [0001] The invention relates to a water supply control switch, in particular to a durable and low-cost automatic water level control switch, which belongs to the field of water supply. Background technique [0002] At present, there are two main types of drinking water in rural areas: one is to drink water by yourself, manually control the water inlet and outlet of the water tower, and observe whether the water in the water tower is full through the overflow of the water tower, and then manually close the water tower until the overflow overflows , this method needs to send people to guard for a long time, which not only consumes manpower, but also wastes water resources; Figure 7 It is a schematic diagram of a representative rural water supply system at present. A water pump 33 is installed in the underground water well 34. An upper check valve 32 is installed on the inner water pipe 5 of the underground water well 34. A traditional water pressure control swi...

Problems solved by technology

[0003] Aiming at the problems of high price and short service life of the current rural water supply equipment, and the problem of manual switching between the village water supply system and the water supply system of individual wells, the present invention provides a durable and low-cost automatic water level control switch, the purpose of which is to reduce the water pressure of the equipment , reduce the cost of equipment; by setting up water towers, the original high-pressure equipment is changed to low-pressure water supply, the original high-pressure water supply switch is changed to an automatic water level control switch, and external water sources are preferentially used to automatically supply water to the water tower or water tank, reducing the cost of water supply equipment , prolong the service life of water supply equipment, so that farmers can benefit
