Problems solved by technology

Under these two installation methods, the sensor can only measure the water quality of a certain depth of water layer, and it is difficult to adjust the measurement depth at any time according to water level changes and different breeding seasons
At the same time, since the water body of the aquaculture pond is rich in organic matter and microorganisms, the sensor is prone to bioaccumulation when immersed in the pond water body for a long time, and frequent cleaning and maintenance are required, otherwise the accuracy of the measurement results will be seriously affected

Embodiment Construction

[0011] as attached figure 1 As shown, the automatic lifting water quality monitoring device is mainly composed of a floating body, a water quality sensor, an electric winch, a stepping motor, a junction box, and a power supply box on the shore. A through hole is provided in the middle of the floating body as a channel for the sensor to go up and down. The winch is fixed on the floating body through the bracket, and the position is located directly above the through hole. The water quality sensor cable is wound on the winch, and rises and falls with the rotation of the winch. The stepper motor is connected with the winch, and the winch is driven to rotate through the rotation of the motor shaft. The junction box is equipped with a controller and a wireless communication module. The controller controls the rotation of the stepper motor according to the set program to automatically adjust the depth of the sensor in the water or raise the water surface. The wireless communicat...

Abstract

The invention discloses an automatic lifting type water quality monitoring device for an aquaculture pond. The device comprises a floater capable of floating on water, a cable winch is mounted on the floater, a floater body below the cable winch is provided with a through hole, and a sensor cable of a water quality sensor is wound on the cable winch to rotate along the cable winch. The water quality sensor is downwardly submerged in water through the through hole of the floater and capable of changing depth in water along with rotation of the cable winch. A junction box is arranged on the floater body, and the cable of the water quality sensor and a cable of a step motor which drives the cable winch are connected to the junction box on the floater. A controller and a wireless communication module are arranged in the junction box, and the junction box is connected to a power supply box on the bank of the pond.

Description

technical field [0001] The invention belongs to the technical field of fish farming, and in particular relates to an automatic lifting water quality monitoring device for farming ponds. Background technique [0002] With the development of the aquaculture industry, water quality monitoring technology has begun to be applied in the aquaculture production process, from the initial measurement of water samples collected in the laboratory to the installation of sensors in ponds for online monitoring of water quality. However, the installation method of the water quality sensor in the pond will affect the accuracy and use effect of the monitoring results. The sensor needs to be submerged to a certain depth below the water surface during measurement. The general method is to fix the water quality sensor on the bank of the pond or install it on a floating body on the water surface. Under these two installation methods, the sensor can only measure the water quality of the water lay...
