Description
Technical field
The measurable flow that the present invention relates to a kind of low pressure pipe irrigation delivery port, especially low pressure pipe irrigation also can quantitatively be controlled the delivery port of flow
.
Background technology
Low pressure pipe irrigation has obtained large-area applying in well irrigation Dryland, and rice made regional low pressure pipe irrigation and also comes into one's own in recent years, and popularizing application prospect is good.But the delivery port of cast iron or plastic material or hydrant are mainly considered the needs that well-irrigated area's dry farming is irrigated at present, and water flow is less, be difficult to meet the large flow of paddy field and irrigate requirement.
In well-irrigated area, due to the restriction of motor-pumped well water flow, the delivery port of simultaneously working generally only has 1～2.Take the rice workspace that surface water is source of irrigation water, flow system flow is larger, and general a plurality of delivery ports are worked simultaneously.Now be necessary to detect and control the flow of each delivery port, comparatively even to guarantee each delivery port water outlet.Yet existing delivery port does not possess the function that flow measurement and quantitative are made discharge.In addition, the screw rod adopting at present opens and closes delivery port, and gland or flap are put down and opened flat closing, vertical with standpipe current all the time, thereby in valve, the loss of flood peak is larger, and delivery port operating pressure and water flow are caused to adverse effect.
Summary of the invention
The object of the invention is can not flow measurement for overcoming current low pressure pipe irrigation delivery port, can not make discharge and the larger shortcoming of the inner loss of flood peak by quantitative.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of low pressure pipe irrigation delivery port is provided, comprise bottom base, upper box body and water outlet stiling basin around standpipe, described upper box body is located on the base of bottom, upper box body bottom is provided with the base plate water inlet that is communicated with standpipe, in upper box body base plate water inlet one side, be provided with two hinged-supports of being fixed by fastening bolt, on hinged-support, be connected with the upset cover plate being placed on base plate water inlet, the bonding circle watertight rubber sheet of upset cover plate upstream face; The end face of upper box body is provided with hand screw headstock gear, and hand screw headstock gear connects upset cover plate by articulated linkage; Upper box body sidewall is provided with a delivery port, at delivery port one side lower part base adjacent, the water outlet stiling basin that is provided with flow measurement scale is installed, and at water outlet stiling basin, one face elevation place, sidewall field is provided with stiling basin delivery port.
Described hand screw headstock gear comprises handle, the nut being connected as a single entity with handle, the screw rod coordinating with nut, casing and bolt, and casing sunk part is corresponding to nut bossing, and casing is bolted on upper box body upper surface.
Described screw rod adopts trapezoidal thread.
Described delivery port is circular.
It is axle upset 0～70 degree that described upset cover plate be take the axis that described hinged-support forms.
Top of the present invention adopts body structure, adapts to large traffic requirement; Improve cover plate opening and closing mode, improve flow condition, play and reduce the inner loss of flood peak and increase the effect that stream; Increase the water outlet stiling basin there is flow measurement scale, can make discharge by quantitative, and can energy dissipating erosion control, prevent that field from washing away, be particularly useful for delivery port flow large, the Rice irrigation district that a plurality of delivery ports are worked simultaneously.By quantitative, make mouth of a river flow, larger even if operating pressure differs, also can guarantee that each delivery port water flow of simultaneously working is basically identical, thereby improve the irrigation water uniformity.

Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
The present invention includes upper box body 1, bottom base 2 and water outlet stiling basin 3 three parts.
Upper box body 1 utilizes cement concrete prefabricated, and its width and length is so that install each headstock gear and be advisable in casing, and casing clear height is upwards overturn 70 ° and is advisable with the cover plate 11 that can make to overturn; When prefabricated, should divide three partial precasts: bottom surface, end face He Liangge side are first, before (having dewatering outlet) and be respectively second and third part below.First's prefabricated components should suitably be arranged reinforcing bar or steel wire, the jack-up top panel in case close overexertion while overturning cover plate 11; The height of second and third partial precast member and width should be more smaller than casing clear span and clear height, so that embed first's prefabricated components, and adopt masonry of cement mortar jointing.While making first's prefabricated components, should reserve screw hole, each fastening bolt holes and base plate water inlet 15, the size of base plate water inlet 15 should be determined according to the actual caliber of standpipe 16.During prefabricated second portion prefabricated components, should reserve the mouth of a river 9, the shape of delivery port 9 can adopt circle, flow discharges size and aperture flow formula calculative determination that delivery port 9 sizes can require according to field.
Each headstock gear installation method that upper box body 1 relates to is as follows: in upper box body 1 bottom surface, hinged-support 13 is installed, upset cover plate 11 upstream faces are bonding or fix a circle watertight rubber sheet 12 with rivet, then utilize pin to be connected with hinged-support 13, utilize fastening bolt 14 fixed-hinged supports 13; Screw rod 8 adopts trapezoid thread screws, screw rod 8 is inserted to the screw rod preformed hole of upper box body 1 end faces, then mounting nuts 5 and casing 6 and bolt 7 successively; Finally, with articulated linkage 10 connecting screw rods 8 and upset cover plate 11, connected mode is latching type hinge.
Handle 4 can be fixed on nut 5, between nut 5 and upper box body 1, is provided with casing 6, and casing 6 is fixed on the upper surface of upper box body 1 by bolt 7, nut 5 is played a supportive role.Utilize handle 4 rotating nuts 5, lifting screw 8, opens and closes upset cover plate 11.Also can adopt pivotable wrench drive screw 8, pivotable wrench production method is: two projections are set on nut 5, making a length is the sleeve pipe that 4～5cm, internal diameter are slightly larger than nut again, two grooves are established in lower end, and groove location is corresponding with two projections on nut 5, both sides, sleeve pipe upper end welding handle, during keying, sleeve pipe groove is blocked to the projection on nut 5, turning handle again, rotary nut 5, lifting screw 8.
Water outlet stiling basin 3 is arranged on upper box body delivery port 9 front lower places, and water outlet stiling basin 3 can utilize cement concrete prefabricated, and its clear span is generally wide 2～3 times of upper box body delivery port 9, and length should be calculated or determine according to test according to aperture horizonally projected jet formula.Stiling basin delivery port 18 width are slightly less than water outlet stiling basin 3 clear span, and on the abutment wall of one or both sides, calibrate 17.The flow that different scales are corresponding passes through waterpower calculative determination, and computational methods are: according to different scales, different ranges, utilize level throw motion formula and means of formula of orifice inverse delivery port 9 water flows.
Can be by observing the flat distance of throwing of delivery port 9 current while pouring water, according to the flow measurement scale on water outlet stiling basin 3, estimation delivery port flow, and can be by the overturn open degree adjusting water outlet flow of cover plate 8 of adjusting.
