The lower end of pipe 10 is connected with triple valve 11, and the output end of triple valve 11 is equipped with appendix 13, and the end insertion of appendix 13
The inside of screen frame 2, the end of appendix 13 are equipped with air jet pipe 15, and the upper end of air inlet pipe 10 is connected with the second air bag 17, and
The upper end of two air bags 17 is provided with snorkel 16, and the upper end of rotation axis 4 is equipped with fixed disk 18, and the outside of fixed disk 18 opens up
There is empty slot 19, one end of hose 20 and floating item 1 are connected with each other, and the other end of hose 20 is equipped with the air bag 21 that swims.
Floating item 1 is set as rectangular configuration, and its outside is provided with 4 in symmetry shape, and the inside of floating item 1 is in symmetrical
Shape is provided with 8 hoses 20, and floating item 1 is connected by hose 20 and the perforation of air bag 21 of swimming, so that the inside for the air bag 21 that swims is filled
Full gas, the air bag 21 that swims is swum on the water surface always, and when water level fluctuation, the air bag 21 that swims moves on the water surface, is convenient for.
Blade 6 is set as arcuate structure, and it is set as incline structure, and blade 64 outside of rotation axis equally
Distribution, the blade 6 of arc are preferably adapted to water flow, convenient for carrying out to water flow.
First air bag 9 is symmetrically arranged with 3, and the outside installation by adhering of the first air bag 9 about the central point of rotating disc 7
In the inside of limiting groove 8.
The air inlet of snorkel 16 is set as the structure tilted down, and its inside is equipped with check valve 14, check valve
14 are mounted on the outside of the air inlet pipe 10 between the first air bag 9 and the second air bag 17, and the end of appendix 13 is equipped with check valve
14, the effective air-flow of the setting of check valve 14 is flow backwards, to prevent aqueous reflux from entering the inside of air bag.
The input terminal of triple valve 11 is separately installed with 3 air inlet pipe 10, and air inlet pipe 10 passes through triple valve 11 and triple valve
11 be perforation connection, and the gas of air inlet pipe 10 enters triple valve 11, so that gas enters in appendix 13 by triple valve 11.
The inside of second air bag 17 is equipped with reset spring 23, and the diameter of the second air bag 17 is greater than the action of empty slot 19,
Under the action of reset spring 23, the fast quick-recovery of the second air bag 17 is round, so that refilling gas inside the second air bag 17, rises
The effect of gas supply is arrived.
Empty slot 19 equidistantly offers 3, and the center vertical line of empty slot 19 and limiting groove 8 in the outside of fixed disk 18
Center vertical line differ 60 ° so that rotating disc 7 and fixed disk 18 are to be staggered, thus when one of air bag is extruded
When, another air bag is not extruded, to play the role of duration gas supply.
The swim surface of air bag 21 offers limiting slot 22, and limiting slot 22 is set as honeycomb structure, and the gas that swims
Capsule 21 is connected by hose 20 and the perforation of floating item 1, and the air bag 21 that swims moves about on the water surface, convenient for breaing up food, improves food
The area of diffusion avoids fish crowded consequently facilitating fish disperses food inside screen frame 2.
Working principle: launching whole in waters first, when having water flow flowing below lake surface, water jet propulsion blade 6
Rotated, so that blade 6 be pushed to be rotated at the bottom, i.e., promotion blade 6 by connecting rod 5 drive rotation axis 4 the bottom into
The upper end of row rotation, rotation axis 4 drives rotating disc 7 and fixed disk 18 to be rotated simultaneously；
When fixed disk 18 is rotated, when 18 outside of fixed disk is contacted with the second air bag 17, due to the position of empty slot 19
Opposite with the position of limiting groove 8, i.e. the outside that is located at the first air bag 9 of limiting groove 8, the first air bag 9 is with not extruded shape
State, while fixed disk 18 squeezes the second air bag 17, the reset spring 23 inside the second air bag 17 is squeezed and shortens,
Gas inside second air bag 17 enters in the air inlet pipe 10 of lower section, and subsequent gas enters the first air bag 9 by check valve 14
Inside, 9 inside gassy of the first air bag gradually become full；
When fixed disk 18 continues rotation, the empty slot 19 of side is overlapped with the second air bag 17, at this time the second air bag
17 lose the extruding force of 18 side of fixed disk, so that internal reset spring 23 restores former long, so that inside the second air bag 17
Space increases, i.e. the second air bag 17 sucks external air by snorkel 16, and extraneous air passes through 16 surface of snorkel
Check valve 14 be inhaled into, the second air bag 17 becomes full again at this time；
Limiting groove 8 and the first air bag 9 misplace at this time, i.e., the outside of rotating disc 7 squeezes the first air bag 9, so that
Gas inside first air bag 9 is entered inside triple valve 11 by air inlet pipe 10, and final gas enters appendix from triple valve 11
13 inside, gas enter the inside of air jet pipe 15 by check valve 14, and final gas sprays Xiang Shuizhong, gas by air jet pipe 15
Body is floated in the form of bubble in the inside of screen frame 2, helps to improve the oxygen content of 2 inside water body of screen frame；
When rotating disc 7 and fixed disk 18 carry out next wheel back rotation, the gas inside the second air bag 17 is extruded again
Into the inside of the first air bag 9, the gas supply of the first air bag 9 is realized, the first air bag 9 is filled；Convenient for duration oxygen supply；
When to berley is carried out inside screen frame 2, food is shed onto the water surface, also, fish move about intake upwards at this time
Food, when fish roll inside screen frame 2, the water surface that seethes moves the drive air bag 21 that swims, swim air bag 21 with
The fluctuating of the water surface and turn upside down, the food inside limiting slot 22 is moved in the water surface, while the air bag 21 that swims is by food
It breaks up, so that scattered inside of the food in screen frame 2, and limiting slot 22 is on the water surface when rolling, 22 internal reservoir of limiting slot
Air will be admitted to underwater therewith, play the role of sending oxygen.
The content being not described in detail in this specification belongs to the prior art well known to professional and technical personnel in the field.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
