Specific implementation process after user installs the device, checks whether the device meets safety requirements, really
It is used to it after recognizing the device qualification, first, protrudes 304 by doorframe and be effectively fixedly connected doorframe 3, by
The middle part that 304 are protruded in fixed block 303 and doorframe is welded with support column 302, and support column 302 is supported at 3 back side of doorframe, so
Afterwards, when gate 5 is closed, at this point, there being a large amount of water inside gate 5, effectively increase the contact surface with water by water bloking piece 4
Product, since the cross section of water bloking piece 4 is in " trapezoidal shape ", water is contacted with the inclined-plane of water bloking piece 4, is resisted to water to increase
Compressive Strength, at this point, effectively being reinforced 5 intensity of gate by stiffener 502, since stiffener 502 is orthogonal in length and breadth
It welds together, and obstructing surface 503 is distributed in the inside of stiffener 502 in " skewed ", is effectively increased gate 5 and water
Secondly contact area effectively carries out switch process, due to Gate-Controlled Switch by buoy 504 to Gate-Controlled Switch 505
505 are fixedly mounted on the surface of obstructing surface 503, and when water level rises, buoy 504, which rises, carries out Gate-Controlled Switch 505
Control, to reach 5 automation control of gate, at this point, by transmission gear a201 and transmission gear b202 effectively to transmission
Device 7 plays booster action, since transmission gear a201 and transmission gear b202 are fitted closely, and transmission gear b202 and biography
Dynamic device 7 fits closely, and the rotation of motor 2 with nutating gear a201 and transmission gear b202 to be rotated, then will be driven
Device 7 carries out elevating movement, at this moment, when gate 5 is opened, will effectively be carried out by the water of gate by filter screen 6 preliminary
Filtering, since filter screen 6 is fixedly mounted on the front of gate 5, the big object rubbish in water intercept by filter screen 6,
Then, elevating movement accurately is carried out to gate 5 by the way that lifter rack 501 is effective, meanwhile, it is effective by flood discharge hole 506
Extra flood is led off, since flood discharge hole 506 is provided with multigroup, and flood discharge hole 506 is evenly distributed on the upper of gate 5
End, when water is more than flood discharge hole 506, water is flowed out by flood discharge hole 506, at this moment, to being diluted of hydraulic pressure.Pass through control
Clamp dog, motor 2, doorframe 3, prior-warning device 301, gate 5 and transmission device 7 are effectively combined, effectively to 5 flood discharge of gate when
Reach early warning effect, when flood pressure is exceeded, prior-warning device 301 sends out alarm, to carry out safe early warning effect.By adding
Strong reinforcing bar effectively reinforces 5 intensity of gate, is welded together since stiffener is orthogonal in length and breadth, and obstructing surface 503 is in " to incline
It is ramp-like " it is distributed in the inside of stiffener, it is effectively increased the contact area of gate 5 and water, to increase the stabilization of gate 5
Property, and then increase the safety of gate 5 used.304 are protruded by doorframe 3 to be effectively fixedly connected doorframe, by
The middle part that 304 are protruded in fixed block 303 and doorframe is welded with support column 302, and support column 302 is supported at the doorframe back side, from
And increase the stability of doorframe 3.Switch effectively is controlled to gate 5 by buoy and carries out switch process, since gate 5 controls
Switch is fixedly mounted on the surface of obstructing surface 503, and when water level rises, buoy, which rises, controls the control switch of gate 5,
To reach 5 automation control of gate.Elevating movement accurately is carried out to gate 5 by the way that lifter rack 501 is effective, meanwhile,
Effectively extra flood is led off by flood discharge hole 506, since flood discharge hole 506 is provided with multigroup, and flood discharge hole 506
It is evenly distributed on the upper end of gate 5, when water is more than flood discharge hole 506, water is flowed out by flood discharge hole 506, at this moment, to water
Press being diluted.
This specific embodiment is only explanation of the invention, is not limitation of the present invention, people in the art
Member can as needed make the present embodiment the modification of not creative contribution after reading this specification, but as long as at this
It is all protected by Patent Law in the right of invention.
