Water leakage detection mechanism

Abstract

The invention discloses a water leakage detection mechanism. The water leakage detection mechanism is characterized by comprising a frequency detection probe and a single-detection probe. The frequency detection probe is fixed to a matching position of a power shaft of a water pump and a pump body and provided with an exposed water contact surface, and a frequency detection electrode is arranged on the water contact surface; the single-detection probe is fixed below the matching position of the power shaft of the water pump and the pump body and in a water dropping track and provided with a water containing box with an upward opening, and the water containing box is provided with a water containing space for collecting dropping and leaking water; a single-detection electrode used for detecting leaking water in an electric conduction method is arranged in the water containing space; the frequency detection electrode is connected with a frequency detection module; the single-detection electrode is connected with a single-detection module; both the frequency detection module and the single-detection module are located in a control module which can control a driving component where the power shaft is located. According to the water leakage detection mechanism, water leakage detection conclusions of the water pump can be more accurate and reliable due to the combination of the single-detection module and the frequency detection module; water leakage conditions of the centrifugal water pump can be accurately detected and the water leakage detection conclusions are accurate and reliable because the single-detection electrode and the frequency detection electrode are matched with the single-detection module and the frequency detection module which are suitable for the single-detection electrode and the frequency detection electrode.

Description

technical field

[0001] The invention relates to a water leakage detection mechanism, in particular to a water leakage detection device for the shaft sealing part of a centrifugal water pump. Background technique

[0002] Centrifugal water pumps are widely used in water fields, such as irrigation, industry, water sports, etc. Its structure is relatively mature, usually a spiral pump body with an involute profile, and the coaxial pump blades inside are driven to rotate, sucking in the water body axially and discharging it circumferentially, so as to realize the rapid movement of the water body. It can be seen from its structure that the pump blades are fixed shafts fitted in the pump body, and the pumped water body is resident in the space between the pump blades and the pump body, and the pump blades need to be driven by rotating power from the outside of the pump body. Commonly used driving components such as Electric motors, internal combustion engines, etc. In this way, ...
