Multifunctional water tank system for double-channel ecological hydraulic test

Abstract

The invention discloses a multifunctional water tank system for a double-channel ecological hydraulics test. The multifunctional water tank system comprises a reservoir; a water tank filtering water measuring section which is arranged on the upstream side of the reservoir; a water tank body section which is arranged at the upstream of the water tank filtering water measuring section; two water tank energy dissipation sections; a water tank water inlet section which is arranged below the upstream top end of the water tank body section; a rotary vane type adjustable tail gate which is arranged at the downstream of each channel of the water tank body section and is close to the tail end; a water tank water outlet section which is arranged at the downstream of the rotary vane type adjustable tail gate; a test material feeding device which comprises a rigid connecting pipeline, an automatic check valve, a test material feeding bin and a flexible connecting pipeline which are connected in sequence, wherein a pressure pump is arranged in the flexible connecting pipeline; and a programmable logic controller, wherein the output end of the programmable logic controller is connected with theinput end of the rotary vane type adjustable tail gate, the input end of the pressure pump, the input end of the electromagnetic valve and the input end of the variable-frequency centrifugal pump, andthe input end of the electromagnetic flowmeter is connected with the output end of the programmable logic controller.

Description

technical field [0001] The invention discloses a multi-functional water tank system for a double-channel ecological hydraulic test, which belongs to the field of ecological hydraulic test, and is especially suitable for research on the influence of flow velocity on the growth of algae, research on the critical flow rate of algae scouring and shedding, research on the movement of algae residues, etc. field. Background technique [0002] At present, many large-scale water transfer projects have been built at home and abroad. In order to ensure the safety of water supply along the water transfer projects, it is necessary to consider the prevention and control of the abnormal proliferation of algae and other organisms in the canal walls of the water transfer projects. [0003] It is one of the treatment techniques to deal with the abnormal proliferation of algae by using the water flow to scour the algae on the canal wall and accelerate the algae shedding and transportation.

AI Technical Summary

Problems solved by technology

[0007] 1. The design flow rate range of traditional indoor test tanks is small. The flow rate of common open channel flow tanks is generally below 0.6m / s. It is difficult to capture the critical flow rate of algae flushing and shedding

[0008] 2. Traditional indoor test tanks do not have the temporary cultivation conditions for algae in dynamic water environment

[0009] 3. The traditional indoor test tank does not have the conditions to meet the conditions of various algae eco-hydraulic tests at the same time

[0010] 4. The traditional indoor test tank does not have parallel test conditions

[0011] 5. Traditional indoor test tanks do not have the conditions to carry out scale effect research when conducting algae-related eco-hydraulic experiments
