Abstract

The utility model discloses an agricultural water absorption pipe. The utility model is characterized in that a siphon pipe 1 comprises an upstream segment 3 and a launching segment 8 which is larger than the upstream segment 3; the upstream segment 3 can be connected with the launching segment 8 through a three-way pipe 7 connected with a waterflooding hopper 5 through a communicating pipe 4 onwhich a valve 6 is arranged; the water outlet 9 of the launching segment 8 is provided with a plug 10 which can be opened. When the agricultural water absorption pipe is used, the water outlet 9 is sealed by the plug 10 first, and the launching segment 8 is filled through the waterflooding hopper 5; then water can be pumped by closing the valve 6 and opening the plug 10. The utility model which does not need an expensive special device has the advantage of energy saving, used for pumping, or flood preventing, or irrigating, or silt draining.

Description

Agricultural water absorption pipe

The utility model relates to water intaking, and drainage equipment specifically is a kind of Agricultural water absorption pipe that is used for the overhead reservoir in riverbed, river water intaking usefulness.

The reservoir in the many areas of China, the riverbed in river are above ground level, in order to control flood, to arrange silts, irrigate, the special-purpose pumping equipment of needs.As water pumper etc., these special-purpose pumping equipment expense height, power consumption are big.For this reason, the someone adopts a siphon pipe, and its water inlet is put in the water of riverbed one side, and delivery port is put in the outside, riverbed, and delivery port is lower than water inlet.Do like this and can save the energy and special-purpose pumping equipment, still, when beginning, need the air in the siphon pipe be extracted out, make siphon pipe enter duty so that the water in the riverbed is introduced siphon pipe with special-purpose air exhauster.

The purpose of this utility model is to use special-purpose pumping equipment expense height, power consumption greatly at drawing water reservoir that is above the ground level from the riverbed or the river course, need be equipped with the problem of special-purpose air-extractor and use general siphon pipe to draw water, provide a kind of siphon principle that utilizes to draw water, but need not the Agricultural water absorption pipe of special-purpose air-extractor.

The utility model is achieved through the following technical solutions: Agricultural water absorption pipe is a siphon pipe with water sucking mouth and discharge outlet.Siphon pipe comprises forebay and following water section.Following water section is greater than forebay.Be provided with the water filling bucket that is communicated with siphon pipe by communicating pipe between forebay and the following water section.Communicating pipe is provided with valve.Able to turn on or off shutoff is housed on the discharge outlet of following water section.

Forebay can be connected by the three-way pipe that has water filling bucket and valve with following water section.

Shutoff on the following water section discharge outlet can be a seal cover that has sealing gasket of borrowing the screw thread combination; It can be a buckle closure that has sealing gasket and compress by locking member; It also can be the elastic packing ball of an inflation.

During use, forebay is put in riverbed one side and the water sucking mouth is immersed in the water, following water section is put in the river levee outside, with shutoff discharge outlet is sealed earlier, open the valve of water filling bucket communicating pipe, by the water filling of the downward water section of water filling bucket, after the following water section fills with water, close the valve on water filling bucket communicating pipe, open the shutoff on the discharge outlet again, the water in reservoir or the river course borrows siphonage to flow out reservoir or river course by forebay and following water section.

The utility model need not to use too much pumping equipment, need not to purchase air exhauster, can realize the purpose of drawing water by manual to the water filling of water filling bucket, the manual shutoff that opens and closes discharge outlet.When the big flow of need draws water, can adopt the siphon pipe of big caliber, big water filling bucket, also a plurality of siphon pipe parallel connections can be interconnected the water filling bucket on it, by water filling bucket water Duan Jiashui under each is siphonal.When adding water, the water filling bucket of the siphoning installation of big flow can adopt the water pumper water filling.Siphon pipe can adopt metal tube, plastic tube or rubber tube.The utility model was both available to draw water, irrigates, and also can be used for row and becomes silted up, controls flood, and cost is low, and is easy to operate, saves the energy.

Fig. 2 is the right side view of Fig. 1;

Fig. 3 is the shutoff organigram;

Fig. 4 is that the utility model is used schematic diagram;

Fig. 5 is the utility model schematic diagram that uses in parallel.

The utility model is described in further detail below in conjunction with accompanying drawing:

As shown in Figure 1, Agricultural water absorption pipe described in the utility model is a siphon pipe 1 that has water filling bucket 5.Siphon pipe 1 comprises forebay 3 and following water section 8, and following water section 8 is greater than forebay 3.Water filling bucket 5 is contained in the joint of forebay 3 and following water section 8.Forebay 3 can be a pipe with following water section 8, also can be two pipes, interconnects by a three-way pipe 7, and water filling this moment bucket 5 is by linking to each other with three-way pipe 7 communicating pipe 4.Valve 6 was housed on communicating pipe 4.One of installing can open and close shutoff 10 on the discharge outlet 9 of following water section 8.As shown in Figure 3, shutoff 10 can be the threaded cap 11 of a band sealing gasket 12, can be the buckle closure 14 of a band sealing gasket 15, and buckle closure 14 is hinged by bearing pin 16 and discharge outlet 9, is held on the discharge outlet 9 by locking member 13.Shutoff 10 also can be an elastic packing ball 18, and the air-inflating tube 17 of a gas nozzle is arranged on the elastic packing ball 18.Elastic packing ball 18 is put into the discharge outlet 9 that band closes up, make elastic packing ball 18 inflate and be stretched in the discharge outlet 9, discharge outlet 9 is sealed by air-inflating tube 17.Loosen the valve on the air-inflating tube 17, make 18 exhausts of elastic packing ball and taking-up from discharge outlet 9, discharge outlet 9 is opened.Fig. 4 is positioned over schematic diagram when drawing water on the river levee 19 with the utility model.Fig. 5 is with the arrangement in parallel of three Agricultural water absorption pipes, and the schematic diagram of communicating pipe 20 is housed on the mutual water filling bucket 5.
