Measuring device for sludge sedimentation ratio of sludge sedimentation tank

The invention discloses a sludge sedimentation tank sludge sedimentation ratio measuring device which comprises a tank body, a partition plate is installed in the middle of the tank body, fixing plates are installed above the surfaces of the two ends of the partition plate, a first motor is installed on the fixing plates, a gear is fixedly installed at the output end of the first motor, a rack is slidably installed on one side of the gear, and the rack is meshed with the gear. A releasing mechanism is installed below the surface of one end of the rack, a measuring cup is detachably installed on the releasing mechanism, and a cleaning mechanism is installed on one side of the fixing plate. The first motor rotates to drive the gear to rotate, the gear is meshed with the rack, the gear drives the rack to move up and down, the rack drives the measuring cup to move, muddy water is sampled, the sludge sedimentation ratio is obtained through electric driving sampling and accurate calculation through a formula, error
