Description

TECHNICAL FIELD

[0001] The utility model relates to water pump technical field especially relates to an automatic water pump. BACKGROUND

[0002] As the core equipment of liquid delivery and drainage systems, water pumps are widely used in various industrial, agricultural, and civilian fields. Their working principle is mainly based on the action of centrifugal force, which absorbs and accelerates liquid from the inlet through rotating impellers, and then discharges high-speed liquid from the outlet to form a continuous water flow. In modern technology, the design of water pumps is continuously optimized to adapt to different environments and application scenarios. For example, submersible pumps made of explosion-proof materials can safely operate in flammable and explosive environments, while water pumps equipped with intelligent control systems can automatically adjust their working status according to the liquid level changes, achieving efficient and energy-saving liquid management. These technological advancements not only improve the performance and reliability of water pumps, but also expand their application range, making them indispensable key components in various liquid handling systems.

[0003] Some valve chambers are in special geographical locations, and the gas-liquid linkage valve is at a low position. Every time during the flood season, there is a risk of being flooded by river water, causing the safety control device to fail, resulting in the execution mechanism being buried by river water, and the observation hole cannot be excluded after the water enters. During the winter supply period, the residual water in the execution mechanism freezes due to the low temperature, causing the gas-liquid linkage valve to be unable to act, resulting in a safety hazard.

[0004] The patent document CN206957934U discloses a water pump based on PLC control, which solves the defect that the existing water pump is directly sunk to the bottom of the water to work, and cannot alarm and adjust the depth of pumping. It includes: a pump body with a motor inside, a support frame supporting the lower end of the pump body outside the pump body, and a liquid level meter connected to the support frame outside. The PLC controller is connected to the liquid level meter and alarms according to the lowest liquid level of the liquid level meter. The support frame supports the pump body to avoid direct contact between the lower end of the pump body and the bottom of the water. The liquid level meter can measure the depth of the pump body in the water body or determine the relative depth of the pump body in the water body. The PLC controller is connected to the alarm, and when the liquid level meter indicates the lowest liquid surface, the PLC controller controls the alarm to alarm and reminds the worker to adjust the depth of the water pump. In this way, the worker does not need to always pay attention to the pumping depth of the water pump.

[0005] In the prior art of the above patent, the device measures the liquid level depth by the liquid level meter to control the water pump to pump water. However, the liquid level meter does not have a protection component. If the liquid level meter is damaged due to external factors, it will affect the normal start of the water pump. Secondly, when the weather is cold, the water body will freeze, which will affect the normal work of the liquid level meter and cannot complete the normal pumping work. UTILITY MODEL CONTENTS
