Between circular hollow tube, the tube wall of the circular hollow tube bottom of inner side is provided with sliding bottom 9, above sliding bottom 9
The pressure regulation groove 4 of up/down perforation, the sky between sliding bottom 9 and pressure regulation groove 4 it is provided with on the upper surface of the circular hollow tube in outside
Between constitute the sliding stroke chamber 10 of inner circular hollow pipe, it is characterised in that be positioned at the sliding bottom of circular hollow tube of inner side
Outside and be provided with between the circular hollow inside pipe wall in outside for seal sliding ring, sliding ring includes position
Lip in top the first y-type seal ring 8a upward and be positioned at the lip second y-type seal ring 8b down of lower section, outermost one
The body 1a bottom spinning of joint circular hollow tube, on base 2, base is provided with intake tunnel 3, the water inlet of intake tunnel 3
3a is arranged on the sidewall of base, and outlet 3b is connected with the water inlet of the interior joint circular hollow tube lower end；Water passes through water
Entering telescoping tube from water inlet 3a by the outlet 3b of intake tunnel after pump pressurization, under the effect of hydraulic pressure, telescoping tube is upwards
Stretch out, be positioned at the lip of the second y-type seal ring of the sliding bottom lateral lip mouth down of the circular hollow tube of inner side at water simultaneously
Open under pressure effect, be close to be positioned on the circular hollow inside pipe wall in outside, formed and seal structure, it is ensured that telescoping tube was rising
In journey water-tight, the first y-type seal ring not pressurized in this uphill process, can relatively slide；After irrigation completes, telescoping tube bounces back
Time, the water in telescoping tube is refluxed by intake tunnel, and telescoping tube inner chamber forms negative pressure, in atmospheric pressure is pointed to by pressure regulation groove
The lip of the circular hollow tube of side the first y-type seal ring upward applies pressure, and the first y-type seal ring lip is opened, and is affixed on position
On the circular hollow inside pipe wall in outside, being formed and seal structure, under the effect of negative pressure, telescoping tube can bounce back rapidly, this retraction
During the second y-type seal ring not pressurized, can relatively slide.
For ensureing using effect, described telescoping tube upper end is equipped with rotary nozzle, and rotary nozzle spinning is at the interior pitch circle
The upper end of the body 1b of shape hollow pipe；Described rotary nozzle is the Application No. of applicant's earlier application
" latent ground formula rotary nozzle " or " the latent ground formula rotation spray of Application No. " 201420601534.5 " of " 201320826515.8 "
Head ", can be connected by the screw thread 5 of the upper end of the body 1b of the interior joint circular hollow tube；
There is external screw thread 6 on the outer wall of the body 1a bottom that described outermost one saves circular hollow tube, the inwall of base sets
Being equipped with female thread 7, outermost one saves the body 1a bottom of circular hollow tube through external screw thread 6 and female thread 7 spinning at the oral area of base 2
On.
Service condition of the present utility model is, rotary nozzle is contained in the body 1b of the interior joint circular hollow tube of telescoping tube
Upper end, the inlet opening of base is connected with the water side of the branch pipe(tube) of multi-functional Irrigation and fertilization system, and water is pressurizeed by water pump
After enter telescoping tube from water inlet 3a by the outlet 3b of intake tunnel, under the effect of hydraulic pressure, telescoping tube protrudes upward, with
Time be positioned at the lip of the second y-type seal ring of sliding bottom lateral lip mouth down of circular hollow tube of inner side under hydraulic pressure effect
Open, be close to be positioned on the circular hollow inside pipe wall in outside, formed and seal structure, it is ensured that telescoping tube does not leaks in uphill process
Water, the first y-type seal ring not pressurized in this uphill process, can relatively slide, final water has sprayed irrigation from rotary nozzle；When
After irrigation completes, switching off the pump, during telescoping tube retraction, the water in telescoping tube is refluxed by intake tunnel, and telescoping tube inner chamber is formed
Negative pressure, atmospheric pressure by pressure regulation groove be pointed to inner side circular hollow tube lip upward first y-type seal ring apply pressure
Power, the first y-type seal ring lip is opened, and is affixed on the circular hollow inside pipe wall being positioned at outside, is formed and seal structure, in negative pressure
Under effect, telescoping tube can bounce back rapidly, the second y-type seal ring not pressurized in this retraction process, can relatively slide.Make through actual
With, reaching extraordinary using effect, concrete outcome is as follows:
Applicant uses the " a kind of for multi-functional fertigation of Application No. 201520209803.8 respectively to 50 groups
The lifting column of system " the merit of lifting column sealing lift of as a control group with 50 groups of the application of function Irrigation and fertilization system
Can add up respectively as experimental group by Irrigation and fertilization system, experimental group and matched group all use identical rotary nozzle, result
As follows:
| Project | Total quantity | Parameters of pump | Water leakage (m per hour3) | It is not fully retracted quantity |
| Experimental group | 50 | 160m3/h-50m | 3 | 0 |
| Matched group | 50 | 160m3/h-50m | 151 | 21 |
In above-mentioned experiment, matched group cannot rise to the highest due to discharge of pump too small (power is too small) lifting column all the time,
Sealing ring cannot be normal, and therefore the gap between two circular hollow tubes constantly leaks, and water leakage is big, and rear applicant is to comparison
Group uses the method increasing pump power to carry out continuance test, and final employing parameters of pump is 300m3/ h-50m(lift 50m, goes out
Water yield 300m3/ h) time, the lifting column of matched group just rises to the highest, makes sealing ring laminating work, it is ensured that water-tight, therefore by upper
State situation it should be apparent that at lifting column of the present utility model substantially without leaking, only need low power water pump to reach
Using effect, saves water and energy, by hydraulic pressure during rising, and the negative pressure the most reasonably utilized during retraction, it is ensured that telescoping tube is fully retracted,
Its novel structure is unique, and advantages of simple easily produces, low cost, good airproof performance, energy-saving and water-saving, and shrinkage is strong, retraction speed
Hurry up, the scope of application is wide, easy to use, effective, has good Social and economic benef@.
Applicant, it is noted that the above-mentioned a kind of embodiment pointed out of the application, is not meant to limit this Shen
Protection domain please, every equivalent or equivalent alternative means are made the technical side the most identical with technical scheme
Case belongs to the protection domain of the application.
