Description of drawings
Fig. 1 is a schematic top plan view of the present utility model;
Fig. 2 is the A-A cross-sectional schematic among Fig. 1.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As depicted in figs. 1 and 2, the utility model is to be made of aqua storage tank 9 and corrosion test groove 7, and both make by corrosion-resistant withstand voltage tempered glass.Be connected by water circulation system between aqua storage tank 9 and the corrosion test groove 7, be used for realizing exactly for a long time the phenomenon of tide bulge and fall, water circulation system is made of water inlet pipe 1 and rising pipe 5, water inlet pipe and water outlet pipe is PP-R tubing, submersible pump 4,8 provides stable hydraulic pressure, realize flow regulation by ball valve made of plastic 2,11, water inlet pipe is intake all the time, and rising pipe is controlled its water outlet time by energy-conservation timer.Test piece frame 6 and wave paddle 16 are arranged in the corrosion test groove 7, and this test piece frame 6 is made up by pvc pipe and forms, and wave paddle 16 materials are organic glass.Then be connected by corrosion-resistant hinge between wave paddle 16 and the corrosion test groove 7, wall is provided with the wave suppression arrangement 3 that is used to absorb cell wall reflection wave wave around the corrosion test groove 7.The top of aqua storage tank 9 is provided with a rigid support 10, is used to place motor 14 and speed reduction unit 12, and motor 14 is by the output torque that is connected with speed reduction unit 12, and this motor 14 is a buncher, and speed reduction unit 12 is three grades of adjustable worm type of reduction gearings.Have one can realize the eccentric wheel 13 that eccentric throw 10cm-30cm regulates on the output shaft of speed reduction unit 12, this eccentric wheel 13 links to each other with wave paddle 16 by connecting rod 15.
Principle of work of the present utility model is:
Water circulation system is made of respectively water inlet pipe 1 and rising pipe 5.Water inlet pipe 1 is regulated all the time and is intake with flow Q by submersible pump 8 effects, valve 2, under the prerequisite of rising pipe 5 not water outlets, and the water yield that this flow can inject between low-water level LTL and the high water stage HTL to corrosion test groove 7 in 6 hour time; Rising pipe 5 is regulated with flow 2Q water outlet by submersible pump 4 effects, valve 11, energy-conservation timer is controlled the operation that its water outlet in 6 hours quit work and replaces continuously in 6 hours, under the prerequisite that water inlet pipe 1 and rising pipe 5 are worked simultaneously, the water yield that can get rid of between low-water level LTL and the high water stage HTL from corrosion test groove 7 in 6 hours.The so just sustainable semi-diurnal tides that simulates 6 hours ebb tides of 6 hours rising tides.Certainly, the diurnal tide of the control time of flow by control valve 2,11 and the energy-conservation timer 12 hours ebb tides that can also simulate that flood tide in 12 hours.
Wave paddle 16 clocklike moves thereby promote corrosion test groove 7 maritime interior waters because the output torque of eccentric wheel 13 is made reciprocally swinging by connecting rod 15, and then simulates the fixing wave of waveform.By regulating speed reduction unit 12, can change the rotating speed of eccentric wheel 13, thereby the frequency of change wave paddle 16 swings is to reach the purpose that changes the wave wavelength; By regulating effective eccentric throw of eccentric wheel 13, can change the amplitude of fluctuation of wave paddle 16, thereby the wave that changes wave is high.In addition, the wave suppression arrangement 3 that can absorb cell wall reflection wave wave can make the wave paddle 16 new waves that produce do not interfered, help with corrosion test groove 7 in wave more uniform and stable.Thus, just can effectively simulate the marine environment of different time different waters.
Test piece frame 6 positions are marine corrosion simulated test site, simulate marine atmosphere zone successively to the bottom from test piece frame 6 tops, waves splash about district, tidal range district, water immersion district and seabed earth district five marine corrosion districts band, hang up the test piece of some to study in pairing test piece frame 6 parts of corresponding corrosion region band.
Treating that the debugging of above each position is regulated finishes, this marine corrosion simulated test unit just can be for a long time simulated marine corrosion environment effectively automatically, carry out the corrosion coupon test of metal material in marine environment.
