Embodiment 1
According to Fig. 1 and Fig. 2, a kind of immersible pump suitable for decompression method exploitation combustible ice described in the present embodiment includes Electric machine casing 1, the motor being mounted in electric machine casing, and it is connected to the pump housing 3 of electric machine casing lower end;The motor includes The stator winding 11 being fixedly mounted in electric machine casing, and be mounted in electric machine casing and in stator winding by bearing The rotor 12 in week;The rotor lower end is across electric machine casing and rotor and electric machine casing lower end by close Seal bearing connection;The electric machine casing lower end is in infundibulate low between the senior middle school of periphery;The pump housing lower part is equipped with water inlet, described Pump housing side upper end is connected with out liquid interface 31, goes out liquid interface for connecting liquid-transport pipe-line.
It is rotatablely equipped with impeller 32 in the pump housing, the first ratchet is connected between the impeller and the shaft of rotor Component 321.
The shaft of the rotor is passed down through the pump housing, and the lower end of shaft is connected by the second ratchet assembly 41 There are one drilling rods 4.
The rotor drives drilling rod to rotate clockwise by the second ratchet assembly, and the rotor passes through the first spine Wheel assembly driving impeller rotates backward.
There are two functions for the motor tool of immersible pump in the present invention, drilling rod can be driven to rotate when motor rotates clockwise, this Sample immersible pump can be got into the rock stratum below immersible pump installation site by drilling rod(Combustible ice exploits the rock stratum of bottom), in this way The state that immersible pump can be kept upright does not need additional fixation;When motor rotates counterclockwise, only impeller rotation makes Immersible pump is in running order, and due to being provided with the second ratchet assembly, drilling rod will not be with wheel rotation, it is ensured that the normal work of impeller Make.
The pump housing lower end is connected with multiple support legs 33, and the second ratchet assembly is between each support leg, in drilling rod It pierces after the rock stratum of seabed, immersible pump is against by support leg on rock stratum, and drilling rod then ensures immersible pump and is kept upright state.
Be located above electric machine casing in the electric machine casing and gas generating unit 5 be installed, the electric machine casing it is upper There are one the intake valves 7 for the metal material being vertically arranged for end welding;The gas generating unit is connect with intake valve;The gas It is loaded with the mixture of potassium chlorate and manganese dioxide in generating means, is equipped with to heat gas outside the gas generating unit The heating device 6 of generating means, the heating device are electrically connected with the controller mounted on electric machine casing inner top.The heating Device is ceramic heater or electromagnetic heater.When heating devices heat, potassium chlorate, which decomposes, generates oxygen, and gas fills Air pressure in setting gradually rises, and is filled in electric machine casing by intake valve.
There are one horizontal seat boards 70, seat board intermediary form air admission hole, the valve seat for molding in the intake valve 7 Plate lower end is equipped with seals the valve block 71 to offset with seat board, and the first bullet is equipped between the valve block lower end and intake valve lower end Spring 711;There are one the heaters 72 of annular for installation above the seat board in the intake valve;It is located in the intake valve It is provided with above heater and valve block and is wound into columned low-melting-point metal silk 73;It is located at low-melting-point metal in the intake valve Silk top is set there are one to the compression valve block 74 that is compacted the low-melting-point metal silk of fusing downwards, the compressions valve block upper end and There are one second springs 741 for installation between intake valve upper end.
The heater is electrically connected with controller.The heater is electromagnetic heater.
The electric machine casing outer wall is equipped with first pressure sensor module,InstituteIt states and second pressure is installed in electric machine casing Sensor assembly, the first pressure sensor module 91 and second pressure sensor assembly 92 pass through conducting wire with controller respectively It electrically connects or is electrically connected by radio;When the pressure value that the first pressure sensor module detects is more than second pressure The pressure value that sensor assembly detects, controller controls heating device and starts work, until second pressure sensor assembly detects To pressure value be more than the pressure value that detects of first pressure sensor module after, controller controls heater stop, then The fusing of low-melting-point metal silk is made intake valve thoroughly be blocked by the fever of control heater.
The controller can be SCM system, and controller is accompanied with accumulator and powers for it.The controller is furnished with Reception of wireless signals module can start work by remote control control controller.
The low-melting-point metal silk is scolding tin.The valve block is preferably heat resistant rubber, in melts soldering tin and will be on seat board Air admission hole it is completely enclosed during, it is ensured that the sealing performance between valve block and seat board.More preferably in valve block upper surface pair The position of air admission hole is answered to connect one layer of heat insulation layer.
Since the working depth of immersible pump is larger, if being first filled with high pressure gas in electric machine casing before immersible pump installation Body, then the sealing performance for sealing position of bearings wants very high, is otherwise difficult to avoid that high pressure gas leakage, once high pressure gas Leakage, and is difficult to ensure the air pressure in electric machine casing, and each immersible pump due to working environment it is different, the pressure in residing water Value is different, and it is just right to be also difficult to institute's inflatable body pressure for inflation in advance.Therefore in the electric machine casing of immersible pump in the present embodiment The preset air accumulator filled with high pressure gas or liquid gas of interior elder generation waits for air accumulator during immersible pump dive to operating position Interior gas is gradually filled in electric machine casing.In addition, in order to ensure being absolutely sealed for electric machine casing top, heated using heater Scolding tin keeps intake valve completely enclosed, avoids leaking for gas molecule in electric machine casing.
In addition, pressure of the air pump in air accumulator be reduced to when pressure is suitable in electric machine casing, can be by air accumulator Interior gas as much as possible continues to be filled in electric machine casing, the opposite amount for reducing gas storage needed for air accumulator.The air pump may be selected Two-stage or the plunger pump of three-level supercharging.
The gas generating unit is canister, and canister inner wall is equipped with erosion resistant coating, is installed in gas generating unit There are temperature sensor, gas generating unit to be coated with heat-insulating material;The temperature sensor is electrically connected with controller, is being heated Device stop heating, and temperature sensor detect temperature be less than set temperature when, controller just start heater work.
