The alternating change for drastically raising and reducing by force, water hammer effect have great destructiveness：Due to the generation of water hammer so that pressed in pipeline
Power increased dramatically to even more than ten times of several times more than normal pressure, and its harm is very big, can cause the rupture of pipeline, influence to produce
And life；Pressure is too high, will cause the rupture of pipe, conversely, pressure is too low and can cause the collapsing of pipe, can also damage valve
And fixture.
For another example, U.S. Application No. 5782578 discloses " waterpower timing irrigation device ", and its shortcoming and Chinese patent mandate are public
Announcement CN103444495B is the same, only adapts to the situation that pipeline low discharge supplies water, but farmland surface irrigation flow is larger, otherwise it is real
Now not, or device is huge.
For another example, the Chen Jun of Shandong Agricultural University Master's thesis " research of canal irrigation billow the automatic device for irrigation ", in May, 2007
Deliver within 20th, although realizing channel intermittent water application, needs build regulation and control pond in the side of channel, occupy farmland, and device

Operation principle
Referring to shown in Fig. 1-6, when the water flowing in main water channel, water wheels are driven to rotate, by connecting water wheels and driving gear
Connecting shaft drives driving gear to rotate, and driving gear and driven gear engagement, when driving gear rotates, driven gear is also simultaneously
Rotating, driven gear and cam coaxial link together, and driven gear rotates simultaneously with cam, are managed according to the work of cam, when
When the driven member of connection gate moves to the A-B-A camber line sections on cam, gate is opened by rising in the chute of branch's water channel,
Current enter field by branch's water channel by gate, and driven member is lock in the A-B-A camber lines section residence time of cam
Door discharges water duration；When the driven member for connecting gate moves to the A-C-A camber line sections of cam, the decline of gate companion driven member
And close, current can not enter field from branch's water channel by gate, and driven member stops in the A-C-A camber lines section of cam
Time, that is, it is off the duration that discharges water；Due to the active force of the water of constant flow in main water channel so that water wheels are rotating always, week
And renew, gate is also in unlatching, closing, the reciprocation cycle motion opened, truly realize not against electric power or
Manpower drives the folding of gate, so as to the purpose of batch (-type) irrigated farmland；Change the diameter of follower, it is easy to adjust cam
Movement velocity, that is, the length in regulating gate open-close cycle；The different arc shape of cam is designed, is also just easy to
Regulating gate open and closure time, in theory, can have any number of gate opening and closure ageing.
It is of the invention with traditional Surface irrigation generally compared with, its uniformity of irrigation water appilcation is big, water-saving result is good；With drip irrigation and spray irrigation
Etc. comparing, its investment is small；Device Controlled irrigation is convenient, and connection is simple, is not required to take other soil, material saving, operation
Simply.
