Abstract
The invention provides a dissolved oxygen sensor probe for aquaculture. The dissolved oxygen sensor probe comprises a cylindrical shell and a protective cover rotationally connected to the bottom end of the cylindrical shell. The bottom end of the cylindrical shell is a conical section, an external thread is machined on the surface of the conical section, a conical hole is formed in the top end of the protective cover, an internal thread is machined in the conical hole, the conical hole and the conical section are rotationally connected and sealed, the tail end of the conical section stretches into a protective cover cavity, the stretching-in length is 1/3 of the height of the protective cover cavity, a water inlet is formed in the bottom end of the protective cover, a water outlet is formed in the top end of the protective cover, and filter nets are arranged in the water inlet and the water outlet. The structure is simple, contamination of the probe is effectively avoided, the service life is prolonged, and detection precision is improved.
Description
Technical field
The present invention relates to aquaculture detection field, particularly relate to sensor.
Background technology
Dissolved oxygen refers to be dissolved in the water the oxygen of molecularity, is that aquatile survives conditio sune qua non.Natural water
Middle dissolved oxygen is bordering on saturation value (9ppm), and when algae reproduction is vigorous, dissolved oxygen content declines.Water body is polluted by Organic substance and reducing substances and dissolved oxygen can be made to reduce, for culture fishery, Dissolved Oxygen in Water has vital impact to the existence of organism in water such as Fish, when dissolved oxygen is less than 4mg/L, Fish death by suffocation will be caused, therefore, the measurement of Dissolved Oxygen in Water content, the development for culture fishery is significant.
Existing dissolved oxygen sensor structure is complicated, and service life is short, and accuracy of detection is relatively low, haves much room for improvement.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, it is provided that a kind of simple in construction, effectively prevent probe from polluting, increase the service life and the dissolved oxygen sensor used for aquiculture probe of accuracy of detection.
For realizing the object of the invention, provide techniques below scheme: a kind of dissolved oxygen sensor used for aquiculture is popped one's head in, it is characterized in that including cylinder shell, it is rotatably connected in the protective cover of cylinder shell bottom, cylinder shell bottom is conical section, conical section Surface Machining has external screw thread, protective cover top offers bellmouth, female thread it is machined with in bellmouth, bellmouth and conical section spin sealing, described conical section end stretches in protective cover cavity, built-in length is the 1/3 of protective cover housing depth, the nearly bottom of protective cover offers water inlet, the nearly top of protective cover offers outlet, it is provided with drainage screen in described water inlet and outlet.
As preferably, cylinder shell is divided into upper and lower two chambers by discoid control circuit plate, accumulator is set in upper chamber, wireless transmitter and miniature signal processor, bottom chamber arranges fluorescent probe, blue-light source, it is provided with separator disc below discoid control circuit plate, separator disc center offers centre bore, centre bore both sides are provided with angling hole, described fluorescent probe is arranged in centre bore, blue-light source is arranged in angling hole, centre bore bottom is provided with light source optical filter, angling hole bottom is provided with fluorescent optical filter, guide-lighting dish it is provided with below separator disc, guide-lighting disk center offers bellmouth, bellmouth bottom is provided with sensitive fluorescent membrane, described conical section bottom is provided with the oxygen sensing film.
As preferably, sensitive fluorescent membrane is the complex of titanium.
As preferably, fluorescent probe uses PIN photodiode.
The method have the benefit that the present invention passes through rational modification probe internal structure and layout, substantially increase accuracy of detection and service life, and effectively prevent probe from polluting.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
