Lower part of pump impeller driven by motor is connected to low supporter of water lubricating bearing fixed on the flume. Sensor for detecting flow velocity is connected to a display. Bafflers of eliminating vortex are on low part, and planks for equalizing flow are up and low part on left side in flume. Water drain valve and grille are setup inside flume. The invention is able to reproduce dynamic ocean current, possessing features of small floor space and energy consumption.
Description
Technical field
The invention belongs to the proving installation technical field, be specifically related to a kind of device that utilizes the water flow simulation ocean current to carry out the fluid mechanics test, international Patent classificating number: G01N29/00.
Background technology
At present, ocean development is a very promising cause, falls over each other to set out to the ocean in countries in the world, along with being in full swing of marine monitoring work, more and more comes into one's own based on the monitoring of sea bed based platform under water in the three-dimensional real-time detecting system in ocean.But test to the relevant various parameters of current power generation, this just needs a kind of experimental provision that the ocean simulated environment is provided to realize the test of being correlated with, and it be a approach the simplest and the most direct that the various parameters of for example drive marine test, hydroturbine rotor blade, current must obtain by this experimental trough experiment obtaining of the data of influence of hydraulic turbine bearing drive mechanism or the like.But existing experimental tank is all in big R﹠D institution and university, and testing expenses are than higher, and are huge especially as setting up the experimental tank investment.
Summary of the invention
The purpose of this invention is to provide a kind of minitype vertical type ocean current analog simulation device that under laboratory condition, can reproduce the local l-G simulation test of true ocean current.
Technical scheme of the present invention is: in a vertical cabinet, be provided with one in vertical plane the round-robin annular water tank, upper fixed on the tank right side has the variable frequency control drive motor, variable-frequence governor links to each other with the variable frequency control drive motor, and motor-driven pump impeller bottom joins with the elasticity water lubriucated bearing lower support that is fixed in the tank; Be used for the left side that sensor that measurement flow rate uses is fixed on tank, and be connected with velocity indicator; Be provided with the whirlpool fair water fin that disappears in the bottom of water annulus, respectively be provided with homogenizing plate in the upper and lower in water annulus left side; Be provided with a plurality of lacing wires in water channel inside, Draw off valve be installed in the water channel bottom; Left side in the water channel straight portion on tank top is provided with a plurality of current grids.
Good effect of the present invention is: floor area is little, energy consumption is little, cost is low, and it is dynamic, simple to operate to reproduce ocean current truly, and environmental protection and energy saving can reach the requirement of scientific research.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1, the present invention is in a vertical cabinet 4, be provided with one in vertical plane round-robin annular water tank 6, casing 4 materials can adopt the transparent organic glass of easy processing, the vertical round-robin mode of this employing current makes it have visual effect preferably, simultaneously made full use of space and water resource again, size can adopt two kinds of specifications, 2.0m * 3.0m * 0.75m and 1.5m * 2.0m * 0.5m; Upper fixed on tank 6 right sides has variable frequency control drive motor 2, and variable-frequence governor 1 links to each other with variable frequency control drive motor 2, and motor-driven pump impeller 3 bottoms join with the elasticity water lubriucated bearing lower support 5 that is fixed in the tank 6; Be used for the top, left side that sensor 10 that measurement flow rate uses is fixed on tank 6, and be connected with velocity indicator 9; In the water channel of annular water tank 6 bottoms, be provided with the whirlpool fair water fin 7 that disappears, respectively be provided with homogenizing plate 8 in the water channel internal upper part and the bottom in annular water tank 6 left sides; Square water stream channel can be eliminated the vortex that produces in the mobile process of water effectively with disappear whirlpool fair water fin 7 and homogenizing plate 8, so that the ocean current state of its more approaching true ocean; Be provided with 5 road metal lacing wire and sealing rings at the tank middle part, its effect is to guarantee that casing does not have obvious distortion and ne-leakage when being full of water; In water channel bottom Draw off valve is installed, is used for waste water in the emptying experiment pit; Left side in the water channel straight portion on tank top is provided with a plurality of current grids 11, and the effect of current grid 11 is to make current more steady.Flow rate measuring device is made up of micro-stress sensor 10 and supporting with it interface circuit, and its output directly connects the charactron display module, can directly show flow velocity; Other have a serial ports can with the computing machine communication, for the software transfer flow speed data.The test site is arranged in the top of annular water tank, produce the processing of current have vortex through nearly 3/4ths girths of tank at the pump impeller place after, reach the simulation ocean current of whole flow speed stability, basic absence of vortices composition in this zone.
Variable-frequence governor 1 can produce the continuously adjustable three-phase alternating current of 0-50Hz, and in order to the controlling and driving rotating speed of motor, frequency control motor drives pump impeller and rotates, thereby the water that drives in the annular water tank flows, and can produce the continuously adjustable current of flow velocity 0-60cm/s; Current drive and adopt the drive motor way of propelling, adopt this " pushing away " type of drive the most favourable to electrical machinery life, can effectively reduce the wearing and tearing of motor bearings; For eliminating the stress that the water pump wheel produces tank in the drive motor course of work, adopt the lower support that has the elasticity water lubriucated bearing.
The course of work of the present invention is:
Apparatus of the present invention are according to the fluid mechanics relative theory, stepless speed-regulating motor by variable-frequence governor 1 control drives water pump wheel 3 in the current district of flow velocity of an annular region manufacturing at 0-60cm/s, during this time current through the fair water fin water conservancy diversion, eliminate vortex and after the homogenizing plate current-sharing is the current grid, reach whole flow speed stability at pilot region, the simulation ocean current effect of basic absence of vortices composition, and can obtain flow velocity and measured data in real time.
