The invention relates to a sampling sensor for monitoring dissolved oxygen concentration of a fishpond. The sampling sensor comprises a dissolved oxygen probe and is characterized in that the probe is arranged under a probe support; the probe support is fixedly connected with a positioning support through support clamps and equipped with a group of floating balls; a submersible pump used for cleaning the probe is fixedly connected with the probe support through arranging clamps; a submersible pump water outlet is provided with two draining branches; a water outlet of one draining branch is directing to the probe, and the other draining branch is provided with a solenoid valve, which opens and closes sequentially in cycling during working.
Description
technical field [0001] The invention relates to a sampling sensor, in particular to a sampling sensor for monitoring dissolved oxygen concentration in fish ponds which adopts jet flow automatic cleaning. Background technique [0002] Dissolved oxygen is one of the important indicators of fish pond water quality. If the concentration of dissolved oxygen in the water is too low, it will have adverse effects on the growth and reproduction of fish, and even cause large-scale death in severe cases. Therefore, monitoring products dedicated to the continuous measurement of dissolved oxygen in aquaculture ponds came into being. However, since the sampling sensors currently used to monitor the dissolved oxygen concentration in fish ponds are soaked in water for a long time, they are easily polluted by plankton, which directly affects the detection accuracy. At the same time, the sampling sensors polluted by plankton also need to be cleaned frequently. A large amount, and it is easy...
