Abstract

The invention relates to a water delivery regulation device of a combined type jet flow fish pump. The water delivery regulation device comprises a water delivery regulation box group which respectively comprises a drainage box and a flow stabilization box, wherein the drainage box is of a cuboid strip shape and is sleeved outside a drainage taper pipe, water-stop sheets are arranged in the drainage box along the central axis of the drainage taper pipe to form at least two water separation cavities, drainage holes are respectively formed on the interiors of the water separation cavities in the way of corresponding to the wall of the drainage taper pipe, and overflow holes are respectively formed in the lower parts of the front walls of the water separation cavities; a water discharge hole is formed on the lower part of the flow stabilization box and is connected with the water suction hole of a water pump, and the outlet water of the water pump is connected with the water spray cavity of a jet device; the suction port of the jet device is communicated with the small end of the drainage taper pipe; and the a flow regulation plate which can move up and down is also arranged on the front wall of the drainage box and can partially block the overflow holes. The water delivery regulation device is simple in structure, under the condition of not adding any power, the sucked fish water amount can be increased by times, and the ratio of fishes to water is increased; and moreover, the flow of the water pump can be regulated to prevent the taper pipe from being blocked.

Description

technical field [0001] The invention relates to a fish suction pump, in particular to a combined jet fish suction pump, which belongs to the technical field of fishery equipment engineering. Background technique [0002] With the modernization of fishery, fish pumps are more and more put into use as related supporting equipment for cage fish farming. At present, different styles of fish pumps have been developed at home and abroad, such as centrifugal fish pumps, Pneumatic fish-suction pumps, vacuum-type fish-suction pumps, jet-type fish-suction pumps, etc. Among them, the jet-type fish-suction pump has the advantages of less damage to live fish and high survival rate, simple structure, convenient manufacture, and low cost. The efficiency of the jet pump is low, and the suction flow is only about one-third of that of the water pump, so it is not conducive to popularization. [0003] Existing jet-type fish suction pumps, such as figure 1 As shown, it includes a fish suction...
