Automatic fishpond contamination suction machine and contamination clearing method

Abstract

The invention discloses an automatic fishpond contamination suction machine and a contamination clearing method. An MCU controller controls a submerged pump to work, sewage in a fishpond is ejected to the upper space of a filtering container, and the sewage impacts a filtering screen and then is filtered; the filtered sewage returns to the fishpond via a water outlet pipe of the filtering container, and excrement and residual bait falls into the lower space of the filtering container through a gap between the filtering screen and an intermediate baffle plate; and the MCU controller detects signals of three waterproof ultrasonic sensors, calculates out the distances between the front wall, the left wall and the right wall of a vehicle body and opposite walls of the fishpond, control the vehicle body to straightly move forward or turn left and turn right at the angle of 90 degrees, and allows the vehicle body to traverse the bottom of the fishpond along a continuous extension rectangular path in a reciprocation manner. The ultrasonic sensors and the MCU controller are combined to determine the position of the contamination suction machine in the bottom of the fishpond, the contamination clearing path covers the whole fishpond through the reciprocation movement manner, repeated contamination clearing jobs can be avoided, and the efficiency of contamination clearing can be improved.

Description

technical field [0001] The invention relates to a fish pond cleaning technology in the process of aquaculture, in particular to a fish pond sewage suction machine, which cleans fish excrement and residual bait. Background technique [0002] In the process of aquaculture, fish produce a large amount of excrement and residual bait, which will aggravate water pollution and destroy the ecological balance of water body, thus causing the growth of saprophytic bacteria and endangering the health of fish. At present, the following two methods are mostly used to clean up excrement and residual bait in fish ponds: one is to discharge water to clean up, which wastes a lot of water resources, and the other is to use submersible pumps to clean up. Thorough, waste of water, labor-intensive. In the patent literature with the Chinese patent application number CN201410411556 and the title "Automatic underwater cleaning machine without additional power source", the sewage is sucked into the ...

At present, the following two methods are mostly used to clean up excrement and residual bait in fish ponds: one is to discharge water to clean up, which wastes a lot of water resources, and the other is to use submersible pumps to clean up. Thorough, waste of water, labor-intensive

In the patent literature with the Chinese patent application number CN201410411556 and the title "Automatic underwater cleaning machine without additional power source", the sewage is sucked into the bag filter through the water pump for filtration, and the controller detects the ultrasonic waves around the cleaning machine. The signal of the sensor controls the opening and closing of the solenoid valves of the three water outlets on the left and right of the bag filter, thereby controlling the forward direction of the cleaning machine; the cleaning machine has the following disadvantages: first, the sewage only enters from one The mouth of the water pipe is sucked into the cleaning machine, which cannot fully absorb the sewage in front of the cleaning machine, and the cleaning ability is poor; second, after the sewage is filtered through the bag filter, it is easy to cause the bag filter to be blocked, and the water pump is sucked into the bag filter The sewage was not filtered in time, which caused the pressure inside the bag filter to increase, and there was a certain danger; third, the walking of the cleaning machine was powered by the three water outlets on the left and right, so the cleaning machine could not keep moving forward stably and flexibly. poor sex
