Abstract
The invention discloses an omnidirectional current meter of a coupled water quality sensor, of which a technical scheme is as follows: the omnidirectional current meter of the coupled water quality sensor comprises a water quality sensor, and the omnidirectional current meter of the coupled water quality sensor is characterized in that the water quality sensor comprises a housing, a fixed shaft is arranged at the centre of the working surface of the water quality sensor, the fixed shaft is provided with an omnidirectional turbine flow rate vane wheel through a bearing, at least two permanent magnets are mounted on the omnidirectional turbine flow rate vane wheel, and magnetic polarities of neighboring permanent magnets are opposite to each other; the housing of the water quality sensor is further provided with an induction element of a bipolar latch-type Hall sensor, the induction element is matched with the permanent magnets, and the Hall sensor and the water quality sensor share a power supply circuit and a cable. The omnidirectional current meter of the coupled water quality sensor has the following advantages that: the omnidirectional current meter can be adaptive to the change of flow direction in a water area of which the flow direction is unknown, or can be carried on a buoy to work; and the bipolar latch-type Hall sensor improves the accuracy and the reliability of flow rate measurement, and shares the housing, relative circuits and cables with the water quality sensor, so that cost is reduced, and structure is simplified.
Description
Technical field
The present invention relates to a kind of daily living article, relate in particular to a kind of omnidirectional type current meter of the water quality sensor that is coupled.
Background technology
Existing flow sensor mainly comes the auto-alignment water (flow) direction by fish lead, vertical tail, generally is only applicable to river etc. and flows to the fluid-velocity survey fields that change less than 180 degree.But when being applied to the automatic monitoring platforms such as buoy of floating on water, because the amplitude of or rotation floating with current may surpass 360 degree, cause the cable winding of sensor on Z-axis, cause current meter correctly not aim at water (flow) direction, cause the fluid-velocity survey error or measure unsuccessfully.And usually water quality and simultaneously measurement of flow velocity, but prior art all is to adopt two independent survey instrument and equipments to finish.
Summary of the invention
The present invention be directed to the existing shortcoming of prior art, and provide a kind of technical scheme of omnidirectional type current meter of the water quality sensor that is coupled, the technical program can realize that changing larger application scenario in flow directions such as buoys measures flow velocity effectively reliably, and combine together with water quality sensor, both solved the orientation problem that flows to of existing current meter fully, interlock circuit and cable have been shared again with the fusion of Hall element, accuracy and the reliability of fluid-velocity survey have been improved, reduced cost, simplified the structure.
The present invention realizes by following technical measures: a kind of omnidirectional type current meter of the water quality sensor that is coupled, it comprises water quality sensor, it is characterized in that, described water quality sensor comprises shell, the workplace center of water quality sensor is provided with stationary shaft, described stationary shaft is equipped with omnidirectional's turbine flow velocity impeller by bearing, on the described omnidirectional turbine flow velocity impeller at least two blocks of permanent magnets is installed, and the polarity of described permanent magnet is that adjacent magnet polarity is opposite; The sensing element of double-electrode latch-type Hall sensor also is installed on the described water quality sensor shell, and described sensing element cooperates with permanent magnet, described Hall element and water quality sensor common source circuit and cable.
Concrete characteristics of the present invention also have, and cleaning is installed on the above-mentioned omnidirectional turbine flow velocity impeller stirs the bubble hairbrush that degass, and the brush that described cleaning stirs the bubble hairbrush that degass slightly contacts with the workplace of water quality sensor.Cleaning stirs the bubble hairbrush that degass and is driven by omnidirectional's turbine flow velocity impeller like this, when measuring flow velocity, can play the effect that dissolved oxygen detects stirrer, and can clean the water quality sensor sensitive area, Effective Raise the serviceable life of water quality sensor.
The Hall element of above-mentioned Hall element is installed in the shell of water quality sensor.Can effectively play a protective role to Hall element like this, and simplify the structure.
Beneficial effect of the present invention is: the technical program solved traditional current meter can't 360 the difficult problem of degree automatic operations, multipole magnet matches with ambipolar Hall element, alternately send the N-S signal, avoid because current meter rocks and sends rub-out signal, improve stability, accuracy and the reliability of current meter, reduced cost, simplified the structure; Cleaning stirs the setting of the bubble hairbrush that degass, and makes the present invention when measuring flow velocity, can play the effect that dissolved oxygen detects stirrer, and can clean the water quality sensor sensitive area, Effective Raise the serviceable life of water quality sensor.
