Problems solved by technology

However, the flow rate is greatly affected by tides, weather, and terrain types. Research in this area in the field is greatly affected by natural uncontrollable factors. It requires ship support and multiple personnel to participate, which is costly, unable to observe in time, difficult to recover, poor stability, and resistance. Weak risk capability
However, in indoor experiments, it is difficult to continuously simulate the water flow velocity less than or equal to 100cm / s, and the reliability of the experimental results is low
It is difficult to carry out relevant experiments on the influence of water flow speed on cultured species and culture facilities, which directly affects the development of culture products and culture facilities in the mariculture industry, which in turn affects the efficiency of culture

Embodiment 1

[0022] Such as figure 1The shown experiment uses a simulated water flow device with adjustable flow rate, which is applied to the experiment of the influence of different flow rates on the behavior of sea cucumbers. Fix the four rectifying grids 3 in the card slots 4 in the back-shaped water tank 1, add 30 cm high seawater to the straight water channel 5 and the curved water channel 6 of the water tank 1, so that the water level in the water channel is higher than the water inlet device 8 and the water outlet Device 11; turn on the frequency converter switch 16, turn the frequency conversion knob 18 to the lowest gear, and make the self-priming water pump 12 run at the lowest speed. After the flow rate is stable, put 10 head of 10ind / kg specification sea cucumber, 20 heads of 100ind / kg specification sea cucumber, and 40 heads of 1000ind / kg specification sea cucumber in two straight channels 5 and two curved channels 6 respectively. The digital video recorder continuously reco...

Embodiment 2

[0024] Such as figure 1 The shown experiment uses a simulated water flow device with adjustable flow rate, which is applied to the experiment on the influence of different flow rates on the stability of the attachment base. Fix the four rectifying grids 3 in the card slots 4 in the back-shaped water tank 1, add 40 cm high seawater to the straight water channel 5 and the curved water channel 6 of the water tank 1, so that the water level in the water channel is higher than the water inlet device 8 and the water outlet Device 11; turn on the frequency converter switch 16, turn the frequency conversion knob 18 to the lowest gear, and make the self-priming water pump 12 run at the lowest speed. After the flow rate is stable, put a corrugated plate in two straight water channels 5 and two curved water channels 6 respectively as the attachment base, and use a digital camera and a digital video recorder to record the movement of the attachment base under the simulated 10cm / s flow rat...

Abstract

The invention relates to an experimental water flow simulation device, in particular to an experimental water flow simulation device capable of adjusting the flow velocity. The device comprises an experimental device, a water flow generating device and a water flow adjusting device, wherein the experimental device comprises a water trough and a plurality of damping screens mounted in the water trough, and the interior of the water trough is divided into a plurality of water channels by the plurality of damping screens; the water flow generating device comprises a self-suction water pump, a water feeding device and a water discharging device, the water feeding device and the water discharging device are communicated with a water inlet and a water outlet of the self-suction water pump through a water inlet pipe and a water outlet pipe respectively and located in different water channels in the water trough respectively, and water pumped into the self-suction water pump through the water feeding device is pumped out through the water discharging device, so that a water flow is formed; and the self-suction water pump is electrically connected with the water flow adjusting device, the frequency of the self-suction water pump is controlled through the water flow adjusting device, and further, the velocity of the water flow is adjusted. The experimental water flow simulation device has the advantages of small space, visualization, simple structure, convenience in operation, low cost, high safety, wide application range and the like.

Description

technical field [0001] The invention relates to simulated water flow equipment for experiments, in particular to a simulated water flow device for experiments with adjustable flow velocity, which can simulate water flow with a flow velocity less than or equal to 100cm / s, and can be observed in real time to conduct research related to oceans and water currents. experiment. Background technique [0002] Marine fishery is an important part of our national economy. In recent years, due to the short supply of natural breeding and fishing products, sea bottom seeding aquaculture has developed extremely rapidly, and has gradually become an important part of my country's offshore fishery. Bottom-seeding breeding needs to comprehensively consider many factors such as water quality, flow velocity, water depth, and bottom quality in the bottom-seeding sea area. The impact of species and breeding facilities. However, the flow rate is greatly affected by tides, weather, and terrain ty...
