Problems solved by technology
[0002] Since the sensors currently used to monitor water quality parameters in fish ponds, such as dissolved oxygen concentration, are soaked in water for a long time, they are easily polluted by plankton, which directly affects the detection accuracy. Regular cleaning is not only a heavy workload, but it is also easy to damage the sampling sensor when removing plankton pollution spots, which affects the service life. These factors have seriously hindered the application and development of aquaculture water quality monitoring products

Embodiment Construction
[0010] The aquaculture water quality sampling device with sensor cleaning function as shown in the figure has a sensor in the main container of the sampling device, a drain hole on the upper side of the main container of the sampling device, and a water inlet pipe below the main container of the sampling device. There is a test water inlet solenoid valve on it, and there is a drain pipe under the main container of the sampling device. There is a drain solenoid valve on the lower water inlet pipe. There is a cleaning branch circuit with a cleaning branch solenoid valve on the cleaning branch circuit. The end of the cleaning branch circuit is connected with a plurality of cleaning nozzles, one of which is directly facing the sensor, and the other cleaning nozzles are arranged around the sensor.
[0011] The working cycle process is as follows: use program control to determine the working cycle of water quality testing and jet cleaning

The invention discloses an aquaculture water quality sampling device with a sensor cleaning function. A drain hole is formed on the upper side of a sampling container; a water inlet pipe is formed below the sampling container; a water inlet testing electromagnetic valve is formed on the water inlet pipe; a drain pipe is formed below the sampling container; a drain electromagnetic valve is formed on a lower water inlet pipe; the outer end of the water inlet pipe is connected with a water pump; a cleaning branch is connected with the lower water inlet pipe between the drain electromagnetic valve and the water pump; a cleaning branch electromagnetic valve is formed on the cleaning branch; the tail end of the cleaning branch is connected with a plurality of cleaning nozzles; one cleaning nozzle straightly faces to a sensor; and other cleaning nozzles are distributed on the periphery of the sensor. The aquaculture water quality sampling device can timely remove sedimentary and adherent smudge of plankton on the surface of the sensor and the surface of the inner wall of the main container of the sampling device through the optimally distributed jet flow cleaning nozzles, so that sampling indexes are accurate, the measurement accuracy is guaranteed, the workload for dismounting the sensor for maintenance can be reduced, and the service life of the sensor is prolonged.
Description
technical field [0001] The invention belongs to aquaculture equipment, in particular to an aquaculture water quality sampling device with a sensor cleaning function. Background technique [0002] Since the sensors currently used to monitor the water quality parameters of fish ponds, such as dissolved oxygen concentration, are immersed in water for a long time, they are easily polluted by plankton, which directly affects the detection accuracy. Regular cleaning not only requires a lot of work, but also easily damages the sampling sensor when removing plankton pollution spots, which affects the service life. These factors have seriously hindered the application and development of aquaculture water quality monitoring products. How to improve the detection accuracy and prolong the service life of this type of water quality sampling sensor is a topic of general concern in the industry. Contents of the invention [0003] The technical problem to be solved by the present inventi...
