hammer harm that water flow pressure change is brought in pipeline during pressure conduit water delivery, water hammer is in having pressure piping, due to certain Kind outside cause（As valve is closed suddenly, water pump assembly stops suddenly）The flow velocity of water is set to change suddenly, so as to cause pressure 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, its harm is very big, can cause the rupture of pipeline, influence to produce And life；Pressure is excessive, will cause the rupture of pipe, conversely, pressure is too low and can cause the collapsing of pipe, can also damage valve And fixing piece.

For another example, U.S. Application No. 5782578 discloses " waterpower timing irrigation device ", its shortcoming and Chinese patent mandate are public Announcement CN103444495B is the same, only adapts to the situation that the small flow of pipeline supplies water, but farmland surface irrigation flow is larger, otherwise it is real Now not, or device is huge.

For another example, the Master's thesis " research of canal irrigation billow the automatic device for irrigation " of the Chen Jun of Shandong Agricultural University, 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 Complexity, runs and easily breaks down, and the water of controlling chamber is slatterned also by siphon pipe.

The content of the invention

Technical problem to be solved in the utility model is to provide a kind of main water channel branch water channel intermittent irrigation device, its is true The interval that channel ground big flow is irrigated is being realized in positive meaning to discharge water control；Device Controlled irrigation is convenient, and simple installation, be not required to Other soil is taken, material saving, operation is simply.

In order to solve the above technical problems, the utility model uses following technical proposals：A kind of main water channel branch water channel interval Irrigation rig, it includes main water channel, branch's water channel, water wheels, driving gear, driven gear, cam, driven member, gate and connection Axis；

Branch's water channel is opened in main water channel side wall, and the water wheels are rotatably suspended above main water channel canal bottom, water Wheel is connected by connecting shaft with driving gear, and driving gear is engaged with driven gear, driven gear and the concentric axis connection of cam, lock Door is snug fit in the sliding slot of branch's water channel side wall, and gate is coordinated by driven member and cam linkage, due to being open water Canal is, it can be achieved that big flow is irrigated, and avoiding pipeline irrigation gate, the tired water hammer effect for opening and closing generation, system are all arranged at out frequently Put on the water channel of formula, without in addition occupying cultivated land, parts are easy for assembly quick, are less prone to failure, and parts are very clear, It is easy to maintenance.

The cam is disc cam.
