An automatic scrubbing device for dissolved oxygen sensor

Abstract

The invention discloses an automatic scouring device for a dissolved oxygen sensor. The automatic scouring device comprises a power output device, a washing device and a sensor connecting protection device. The automatic scouring device is characterized in that the power output device comprises a transmission shaft, self-lubricating ceramic bearings, a protection device-motor bin connecting body, a magnetic coupling, a motor bin and a small-sized DC gear motor and is used for providing power for the washing device to scour the dissolved oxygen sensor; one end of the sensor connecting protection device is connected with the dissolved oxygen sensor in a sealing mode through threads, and the other end of the sensor connecting protection device is connected with the power output device in a sealing mode through threads; the sensor connecting protection device is used for being fixedly connected with the dissolved oxygen sensor and the washing device so as to achieve automatic scouring of the dissolved oxygen sensor. The automatic scouring device for the dissolved oxygen sensor is capable of achieving automatic scouring and static sealing, and has the characteristics of being free of maintenance, capable of achieving self-lubrication and good in stability.

Description

technical field [0001] The invention relates to the technical field of water body detection equipment accessories, in particular to an automatic scrubbing device for a dissolved oxygen sensor. technical background [0002] Dissolved oxygen sensor is an instrument capable of real-time online measurement of dissolved oxygen content in pond aquaculture water. Because of the complex composition of the aquaculture water and the long working time, the sensor is easy to attach a large amount of plankton, residual bait and other pollution. It reduces the accuracy of equipment measurement and the service life of equipment, and increases the maintenance cost and frequency of equipment; the attachment of a large number of pollutants for a long time will directly cause damage to the equipment, and inaccurate monitoring data will also indirectly cause major economic losses in farming A big hidden danger; this kind of sensor equipment used for aquaculture water needs to be cleaned automat...

Problems solved by technology

[0002] The dissolved oxygen sensor is an instrument that can measure the dissolved oxygen content of the pond aquaculture water in real time. Because the water quality of the aquaculture water is complex and the working time is long, the sensor is easy to attach a large amount of plankton, residual bait and other pollution. This reduces the accuracy of equipment measurement and the service life of the equipment, and increases the maintenance cost and frequency of equipment; the attachment of a large number of pollutants for a long time will directly cause damage to the equipment, and inaccurate monitoring data will also indirectly cause major economic losses in farming. A big hidden danger; this kind of sensor equipment used for aquaculture water needs to be cleaned automatically at regular intervals, and the cleaning effect of filtration, water flow, air flow, ultrasonic vibration and other means is not good
