Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is expanded on further, it should be appreciated that these embodiments are merely to illustrate this
Utility model rather than limit scope of the present utility model.In addition, it is to be understood that reading the content that this utility model is lectured
Afterwards, this utility model can be made various changes or modifications by those skilled in the art, and these equivalent form of values also fall within application
Appended claims limited range.
Seeing Fig. 1 is this utility model structural representation, and this structure one immersible pump automatic control structure, including suction nozzle
1, turbine 2, upper cover 3, main shaft 4, swing rod 5, fork 6, pin 7, voussoir 8, connecting tube 9, baffle plate 10, axle sleeve 11, key 12, turbine seat
13, swing rod 5 is connected with main shaft 4 by key 12, and main shaft 4 is connected with turbine 2, and turbine 2 is fixed on turbine seat 13, turbine seat 13
End is fixing with upper cover 3 to be connected, and turbine 2 is provided above with swing rod 5, and swing rod 5 is provided with axle sleeve 11, and axle sleeve 11 is arranged
There are baffle plate 10, the turbine 2 of main shaft 4 side that suction nozzle 1 is provided below, vertically penetrate the leaf at turbine 2 when there being gas through suction nozzle 1
Time on sheet, turbine 2 can drive main shaft 4 to rotate, and swing rod 5 is connected with voussoir 8, and pin 7 is fixed on swing rod 5, and fork 6 passes through
Pin 7 is connected with swing rod 5, and fork 6 end is provided with a bead, and axle sleeve 11 is connected with voussoir 8, and upper cover 3 inwall is provided with even
Adapter 9, voussoir 8 is sphere with the contact surface of fork 6, and voussoir 8 is the conical surface with the acting surface of connecting tube 9.
This utility model simple in construction, swing rod 5 is connected with main shaft 4 by key 12, main shaft 4 provides power, whole gas
Dynamic immersible pump is without circuit part, high at downhole safety.During the drained water of pump, main shaft 4 rotating speed can be automatically controlled, it is not necessary to workman sees
Keep.
During normal work draining, 0.8MPa gases at high pressure are vertically penetrated on the blade of turbine 2 through air intake mouth, and turbine 2 drives
Main shaft 4 rotates, and the impeller of pump is connected with main shaft 4, thus wheel rotation, pump drainage.Now main shaft 4 rotating speed is about 3000r/min.
The bead centrifugal force moment about point of support of fork 6 end is positioned at lowest part, gas outlet less than voussoir 8 gravity to its moment, voussoir 8
Area is maximum.Now whirlpool room pressure is equal to atmospheric pressure, and the kinetic energy of gases at high pressure is converted into the kinetic energy of main shaft 4 and water.
In puddle water-retention by after drained, owing to pump is unloaded, the kinetic energy of gases at high pressure is completely converted into the kinetic energy of main shaft 4,
Main shaft 4 rotating speed raises.When main shaft 4 rotating speed rises to maximum (top) speed 5000r/min, automatic control structure has started to.
The bead centrifugal force moment about point of support of fork 6 end is more than voussoir 8 gravity to its moment, and voussoir 8 is by top to highest point and gear
Plate 10 contacts, and gas outlet area is minimum.Now whirlpool gas pressure inside is gradually increased to 0.8MPa, and main shaft 4 rotating speed is not further added by,
Hereafter automatic control structure will always be in duty, makes main shaft 4 rotating speed maintain about 5000r/min.
Centrifugal action when utilizing fork 6 to rotate vertical component on voussoir 8, makes voussoir 8 move upward, and reduces wedge
The gas outlet size that the conical surface of block 8 is formed with connecting tube 9, thus reduce the rate of discharge of air driven pump, increase volute chamber
Gas pressure, reaches the purpose of reduction of speed and speed limit.When air driven pump normally works, the vertical component that fork 6 acts on voussoir 8 is little
In voussoir 8 gravity, automatic control structure does not works.During pump zero load, along with the rotating speed of main shaft 4 increases, fork 6 acts on voussoir 8
On vertical component be gradually increased, when it is more than or equal to voussoir 8 gravity, automatic control structure works, and pump can be avoided unloaded
Time main shaft 4 speed too high, cause turbine 2 driving so that the size degradation flying out at a high speed under centrifugal action of the blade on turbine 2 is made
Become casualty accident.Fork 6 is arc-shaped with the contact trace of voussoir 8 simultaneously, can gas pressure in continuous control volute chamber, it is achieved
The stepless speed regulation of main shaft 4, makes main shaft 4 stabilization of speed in prescribed limit.
Automatic control structure is arranged on main shaft 4, and its power is from the rotation of main shaft 4, and total eliminates electrical equipment portion
Point, obvious security advantages is had in down-hole；Voussoir 8 is sphere with the contact surface of fork 6, voussoir 8 and the acting surface of connecting tube 9
For the conical surface, the seriality of motion is good, meets the stationarity requirement of motion；Total is all mechanical, simple and compact for structure,
Being easy to inspection maintenance, production cost is low, is suitable for rugged environment under mine.
