Description

Floating type irrigation emitter unit

The utility model relates to a kind of irrigation emitter unit, especially a kind of floating type irrigation emitter unit.

Present existing irrigation emitter unit has the shortcoming that is difficult to overcome.Build such irrigation and drainage facility cost height, need complicated channel and water distribution facility, a large amount of land occupations, the manufacturing cycle is long, and the useless many human and material resources of consumption also are subjected to all multifactor restrictions, irrigation and drainage utilizations such as geography, substrate, SEA LEVEL VARIATION to be subjected to significant limitation.

The purpose of wood model utility is: provide a kind of and be convenient to move low, the multi-functional irrigation emitter unit of cost according to the row's of filling needs.

The technological scheme that described unsteady irrigation emitter unit solves is: it is mainly by distribution wire, motor (or internal-combustion engine) and transmission device, pump shaft and support unit thereof, compositions such as impeller, be characterized in: motor (or internal-combustion engine) and transmission device thereof are installed on the special hull, with the axle sleeve on the pump shaft that its motor (or internal-combustion engine) is connected with connection set, with its bearing, the water seal circle, the reinforced concrete that end cap assembles back and hull gives the goods cast solid, the right-hand member of pump shaft is furnished with impeller and impeller nut, the blade excircle of impeller is furnished with sleeve, the sleeve excircle also gives the goods cast solid with the reinforced concrete of hull, the right-hand member of hull is along being shaped on big discharge capacity low lift water outlet on the impeller shaft axis orientation, upper right at the hull right-hand member, promptly intersect 25 °～60 ° upper right in the scope and be shaped on high-lift water outlet with impeller right-hand member shaft axis, be shaped on the tapered inlet that falls in below the bottom of midship, impeller is assigned in the water intake of hull, is furnished with trash rack in the water inlet.

The utility model has the advantages that:

1, extremely flexible property is good.The user only needs the very short time from buying use, can not scrap because of variation, the changing its course of river of breeding structure, is easy to disperse or concentrate and deal with sudden bloods and droughts, easily repaiies, manageability, antiseptic property be good, is convenient to one-object-many-purposes.

2, investment economizes most.Being cast in the hull reinforced concrete after this facility assembles pump shaft, bearing, axle sleeve gives in the goods, it is by one of the past great engineering, whole commodity have been become, guarantee both quality and quantity to unify to make by manufacturer, loaded down with trivial details manufacture processes such as casting, car, plane have been saved, material is cheap, and manufacturing expense reduces at double.

3, energy-conservation.Because whole facility is provided on the hull, with the lifting of upper and lower water level, do not need the supporting link of repetition irrigation and drainage during work, superior structure Ben Shen and reliability in addition are so can reduce water flow loss to greatest extent.

4, multipurpose.Can inversion mechanical energy on the ground of current energy abundance, can change during small-sized slack season that to mix internal-combustion engine be that power becomes power ship, be specially adapted to aquaculture, can be used for drawing water, deliver bait, fertilising automatically, sprinkle medicine, to large-area aquaculture pond, can quick-acting even oxygen aerations, irreplaceable effect is arranged.

Below in conjunction with the accompanying drawing detail technical solution of the present utility model is described:

Fig. 1 is an A-A sectional view among Fig. 2;

Fig. 2 is the utility model plan view.

The utility model installs distribution wire on the bank in river, again distribution wire is connected on the power distribution unit on the hull 1, as Fig. 1, shown in Figure 2, hull 1 is to have special construction to make with reinforced concrete, is furnished with motor 2 in the one end storehouse of hull 1, with the axle sleeve 6 on the pump shaft 5 that motor 2 output shafts are connected with coupling, with its bearing 4, water seal circle 7, the reinforced concrete that end cap 18 assembles back and hull 1 gives the goods cast solid, the right-hand member of pump shaft 5 is furnished with impeller 10 and impeller nut 11, the blade excircle of impeller 10 is furnished with sleeve 15, sleeve 15 excircles also give the goods cast solid with the reinforced concrete of hull 1, be furnished with the negative pressure suction sleeve 8 that leads to hull 1 external surface at the inner chamber of sleeve 15, on negative pressure suction sleeve 8, be furnished with by-pass cock 9.This device can to join internal-combustion engine be power when becoming power ship and being used for aquaculture changing, and the fertilizer or the medicine that can utilize negative pressure to draw in the ship storehouse apply fertilizer, sprinkle medicine etc. automatically.The left end of pump shaft 5 can directly be connected 10 runnings of drive pump shaft 5 drives impeller with motor 2 ptos with shaft joint 3, also can mix the belt wheel transmission device thereon by 10 runnings of internal combustion engine drives pump shaft 5 impeller.The right-hand member of hull 1 is furnished with capping 13 and stops up along being shaped on low lift water outlet 14 on the impeller 10 shaft axis orientation on low lift water outlet 14.This water outlet 14 can be used as loading and unloading maintenance impeller 10 auxiliary holes when flat, as the power station fixedly during irrigation and drainage, and these water outlet 14 usefulness cappings 13 obstructions.To join internal-combustion engine be that power becomes power ship and is used for aquaculture as transportation bait, when applying fertilizer, splashing medicine automatically, need capping 13 is shed changing, and with these water outlet 14 drainings, this ship can be from boat, in large-area aquaculture pond, and can quick-acting even oxygen aerations.In the upper right of hull 1 right-hand member, promptly be shaped on High-Field journey water outlet 12 with impeller 10 right-hand member axes intersect upper right at 45, be used for the normal pump drainage water in power station.The middle lower bottom part outside of the intermediate portion of hull 1 is provided with and is recessed into toroidal water intake 16, and impeller 10 is assigned in the
