Description
Technical field
The present invention relates to a kind of rice field environmental protection drainage arrangement in Oryza sativa L. environmental protection field of planting.
Background technology
The draining in present rice field is all utilized in quit a post and thus leave it vacant on ridge and discharges water, in order to not make the water in rice field release
Many, people guard it is accomplished by when discharging water.Raining in torrents when, the water in rice field soars, and often the ridge in rice field is washed away, gives
Agricultural production causes loss greatly.In order to ensure the production safety in rice field, we are through studying for a long period of time, and having invented can be certainly
The safety device of dynamic draining..
Summary of the invention
The purpose that the present invention relates to is to provide for a kind of automated management and keeps the water level in rice field and protection ridge not
Safety and environmental protection devices and methods therefor that impacted by heavy rain, the too much rainwater can automatically drained in rice field.
For achieving the above object, environmental protection drainage arrangement in rice field of the present invention mainly includes ring float, buoyancy cavity, interior
Through hole, inlet opening, interior siphunculus, apopore, closure gasket groove, sealing ring, outlet pipe, pedestal.
The bottom of described outlet pipe is stretched in the tubular type hole of pedestal fixing, the outlet of outlet pipe lower end and the pipe of pedestal
Formula hole communicates, and the tubular type hole of pedestal is connected, in water outlet with the waterway outside rice field being built in the earth within rice field
The upper part of pipe is set with ring float.The inner ring surface of the inner via hole of ring float there is apopore, upper at apopore
Face with have closure gasket groove or the upper surface portion of outlet pipe corresponding with apopore on outlet pipe on the inner ring surface of following inner via hole
It is in charge of on face at least upper and lower two seals annular groove, the sealing ring installed in closure gasket groove and the appearance of the upper part of outlet pipe
Face coordinate and enable ring float to slide on the upper part of outlet pipe or in closure gasket groove install sealing ring with interior lead to
The inner ring surface in hole coordinates and enables ring float to slide on the sealing ring of the upper part installation of outlet pipe, and can make ring
Closedown drainage channel is beaten when opening drainage channel, slide downward during shape buoyancy aid upward sliding；At ring float with the rising of water level
And when floating, upward sliding on outlet pipe, then can open drainage channel；At ring float with water level decreasing in water outlet
On pipe during slide downward, it is possible to close drainage channel.
Described outlet pipe is direct piping, direct piping be hollow straight tube, upper end be water inlet, lower end be water outlet
Mouthful；When closure gasket groove is on the inner via hole of ring float, the tube-surface of the upper part of outlet pipe or be fixed on more than pedestal
The tube-surface of the outlet pipe of part is the outer surface of smooth tubular, and the outer surface of smooth tubular is close with ring float
The sealing ring installed in seal ring groove coordinates；When closure gasket groove is on outlet pipe, on the tube-surface of the upper part of outlet pipe at least
There is two seals annular groove.
Described ring float is the cavity body of annular, and the cavity body in ring float is buoyancy cavity, ring float
Inner ring surface is inner via hole, and the inner ring surface of inner via hole has only water outlet on the inner ring surface of apopore and closure gasket groove or inner via hole
Hole, when the inner ring surface of inner via hole has apopore and closure gasket groove, closure gasket groove is at apopore above and below, inner via hole
When only having apopore on inner ring surface, the inner ring surface of inner via hole is smooth sealing surface；One side or outside below ring float
Lower part has inlet opening, has connection inlet opening and the interior siphunculus of apopore, interior siphunculus and inlet opening and water outlet in buoyancy cavity
Hole communicates；Described buoyancy cavity is to produce buoyancy cavity, and the buoyancy that buoyancy cavity produces can the weight of support ring shape buoyancy aid energy
When enough making ring float float on the surface between water surface sealing ring on the upper surface of ring float to apopore.
Described closure gasket groove be install sealing ring annular groove, on the tube-surface of the upper part of outlet pipe or
On the inner ring surface of inner via hole.
Described sealing ring is the seal of the annular with elastic shrinkage function and elastic expansion function, and seal is
Sealing ring or leather cup or rigidity ring body.
Described pedestal is the base being built in the earth within rice field, is built into the hollow base frame in tubular type hole；
The upper part in the tubular type hole of pedestal is used for fixing the lower part of drain pipe, the tubular type hole of the part beyond fixing drain pipe
For conveying water.
During installation, the lower end of outlet pipe is inserted in the tubular type hole in the middle of pedestal fixing；Afterwards, sealing ring is arranged on close
In seal ring groove, then the inner via hole of ring float and the seal ring set being arranged in closure gasket groove are contained in the upper part of outlet pipe
The tube-surface of smooth tubular, or, the inner via hole of ring float is sleeved on the upper part being arranged on outlet pipe
On sealing ring in closure gasket groove.
After pouring water in rice field, when the water surface in rice field is less than the irrigation level set, on the inner via hole of ring float
Apopore is blocked by the upper part of outlet pipe and by the above and below seal ring seal at apopore, is disconnected from water inlet
Hole enters the drainage channel of outlet pipe.When raining, when the water surface in rice field is higher than the irrigation level set, ring float floats
And on the outer surface of the smooth tubular of the upper part of outlet pipe upward sliding, along with the floating of ring float, install
Sealing ring in the closure gasket groove of the inner ring surface on apopore moves upward out and moves on the upper end of outlet pipe or apopore and move
Outside sealing ring in uppermost one closure gasket groove of the tube-surface going out to be arranged on the upper part of outlet pipe, on inner via hole
Apopore exposes the water inlet of the upper end of outlet pipe, and water enters from inlet opening and enters outlet pipe through apopore after inner via hole again
The water inlet of end, then discharges water outside rice field from the tubular type hole that outlet pipe enters in pedestal.After rain stops, when the water in rice field
Position is along with opening of drainage channel after draining, and water level reduces naturally；After water level reduces, ring float is along with along with water level nature
Declining, when water level reaches the irrigation level set, the apopore on inner via hole falls below water outlet along with ring float
The upper end of pipe, the upper end of outlet pipe is stretched in the sealing ring above apopore or apopore declines and enters the upper surface portion of outlet pipe
Divide between the sealing ring installed；Now, the apopore on inner via hole is blocked by the upper part of outlet pipe and by apopore
Above and below seal ring seal, is disconnected the drainage channel entering outlet pipe from inlet opening.
A kind of manufacture method of rice field environmental protection drainage arrangement, it is characterised in that:
