The purpose of this utility model is to provide a kind of experimental provision of measuring algae acoustic reflection feature, is applicable in the laboratory to measure and research algae acoustic reflection feature, for acoustic sounding and the biomass evaluation of marine alga provides advantage.
The technical solution of the utility model is as follows, and a kind of experimental provision of measuring algae acoustic reflection feature is by tank, dual-gripper rail, drag the wing and transducer connector etc. to form.
Tank is square, all is provided with the muffler plate indent on its each side, muffler plate can be inserted wherein, floats in water to prevent muffler plate.
Top, a pair of side at tank is provided with the dual-gripper rail, is connected the motion that the dual-gripper rail supports and the wing is dragged in guiding with the tank side by carriage.
Drag the bottom surface of the wing to have chute one, the transducer slide block is arranged in the chute, and can move along chute.All be provided with the position adjustments bolt hole on the length direction of last extension rod and following extension rod, the two connects by bolt.The transducer connector is connected by the lower end of bolt with following extension rod, and last extension rod is connected with the transducer slide block by bolt, the transducer slide block with drag the chute of the wing to be connected, and can move at the chute cathetus.
Drag the two ends of the wing respectively to be provided with one and drag the wing slip piece, each drag the wing slip piece can be respectively with the dual-gripper rail wherein one be connected.Drag the wing perpendicular to the dual-gripper rail, and can move by dragging wing slip piece straight line on the dual-gripper rail.
The beneficial effects of the utility model are:
(1) the muffler plate indent that is arranged on the tank inboard makes things convenient for the loading and unloading of deadener.
(2) adopt dual-gripper rail and the position of dragging wing together support and control sonar or transducer, realize bigger controllability.
(3) relative position of adjusting upper support bar and lower support bar can be regulated the upright position of transducer easily.
