Embodiment Construction

[0023] Below in conjunction with accompanying drawing, technical scheme of the present invention is further described:

[0024] 1. Open channel high flow rate experimental device

[0025] The open channel high flow rate experimental device is designed on the basis of the original self-circulating open channel experimental device. According to the experimental requirements, one pump or two pumps can be freely selected for self-circulation and non-self-circulation. Among them, the self-circulation Circulation refers to the control of field instruments in D4. wireless intelligent water level monitoring system (see figure 2 ), let the field instrument send a relay signal to control the water pump (see figure 2 ) through the water supply pipe to supply water to the C9. reservoir to provide the water level required for the experiment and then turn on the power of the submersible pump. During the experiment, there is no need to resupply and update the water source; instead of self...

Abstract

The invention relates to a multifunctional high flow velocity intelligent open channel experiment system, which is used to acquire high flow velocity and monitor a water level in a remote way. The multifunctional high flow velocity intelligent open channel experiment system comprises an open channel high velocity experiment device, an adjustable section device, and a wireless intelligent water level monitoring system. The multifunctional high flow velocity intelligent open channel experiment system is advantageous in that the high flow velocity, a section width, and an adjustable water depth can be acquired on an experiment water channel segment, and a water level of a reservoir is monitored wirelessly and adjusted intelligently, and therefore important scientific significance and a practical application value are provided for scientific research working in a field of fluid mechanics such as the acquisition of the flow regime of the different sections, for example, the flow velocities and the water depths.

Description

technical field [0001] The invention belongs to the field of fluid mechanics experimental instruments, and in particular relates to a multifunctional and high-velocity intelligent open channel experimental system, which is suitable for obtaining laminar and turbulent flow states, flow velocities and flow rates in open channel tanks with different cross-sectional sizes and greater flow velocity ranges At the same time, you can choose whether to update the water source and expand the flow according to your needs. Background technique [0002] Water flow movement is a very complex natural phenomenon. The existence of various forces and the laws of their development have not been well grasped so far. The hydraulic model test is modeled on the original body and scaled down according to similar principles. Form a model, and conduct experimental research according to the main forces it receives. In the hydraulic model test, in order to cooperate with the overall hub layout or to s...
