Range.
As shown in Figure 1, the utility model provides a kind of diving pump protector of gas hydrates drilling fluid, including
The tubular protective case 1 being mounted on the outside of immersible pump, the section of bowing of tubular protective case 1 facilitate the peace of support leg 3 in regular polygon shape
Dress.Several pressure springs 7 are connected on 1 inner wall of tubular casing, pressure spring 7 on the outside of buffer board 8 and immersible pump by being affixed.Because diving under water
When pump decentralization deep-well, tubular protective case 1 can be collided inevitably with the borehole wall or shaft bottom and vibrate immersible pump, will affect latent
Water pump service life, buffer board 8 and pressure spring 7 can effectively absorb the vibration of immersible pump, to mitigate the impact force that immersible pump is subject to, improve
In the service life of immersible pump, it ensure that the stability of immersible pump.
The top of tubular protective case 1 is equipped with sealing cover 2, and sealing cover 2 is hinged on 1 top of tubular protective case, fixes in immersible pump
Behind 1 inside of tubular protective case, sealing cover 2 is closed, and seal buckle fastens, and open sealing cover 2 will not because of hydraulic pressure, protects latent
Water pump.Sealing cover 2 is openable to design the installation and removal for facilitating immersible pump.Sealing cover 2, which is equipped with, allows water pumping pipe of diving under water
The water pipe of the pore passed through, immersible pump is plugged in, and the part of 2 pore of sealing cover is connected by sealing ring with sealing cover 2, is prevented
Leak.
The outside of tubular protective case 1 is equipped with several support legs 3, and tubular protective case 1 is connect with 3 threaded engagement of support leg, convenient
Installing and dismounting.The angle formed between adjacent two support legs 3 is 30-60 °, and the support leg 3 of 1 bottom end of tubular protective case is towards having a down dip
Height when tiltedly and the bottom end height of this support leg 3 is than 42 opening state of automatic bottom cover is low, in this way regardless of immersible pump and tubular protect
Shell 1 is fallen into inside deep-well with which kind of posture, and tubular protective case 1 all will not be contacted or be rubbed with the borehole wall, shaft bottom, and influent hopper 4
It will not be blocked by the borehole wall or shaft bottom face, influent hopper 4 has a distance from shaft bottom or the borehole wall, greatly reduces soil or sandstone
Into the possibility of immersible pump, the efficiency that immersible pump extracts gas hydrates is also improved.
The bottom end of tubular protective case 1 is connected with influent hopper 4, and the inside and bottom end of influent hopper 4 are separately installed with sand screen
Net 41 and automatic bottom cover 42, sand control sieve 41 can effectively prevent sandstone in deep-well or soil enters immersible pump, to ensure that
The degree of purity of gas hydrates also protects immersible pump not polluted by sandstone soil.42 top of automatic bottom cover is connected with
Oil cylinder 43, oil cylinder 43 are mounted on the top of influent hopper 4 by hollow out bracket.After the opening of automatic bottom cover 42, bracket does not influence
The bottom of tubular protective case 1 intakes.Immersible pump extract gas hydrates when, oil cylinder 43 can just extend its piston rod to
Automatic bottom cover 42 is opened, is no longer sealed inside tubular protective case 1 at this time, immersible pump can draw water.
The side of tubular protective case 1 also passes through round tube 5 and is equipped with hydraulic balance device 6, and hydraulic balance device 6 includes being mounted on
The annular fixed block 61 of 5 right end of round tube, round tube 5 and 1 inner space of tubular protective case are interconnected, and play the role of buffering hydraulic pressure.
Annular 61 left end of fixed block is connected with slow pressure piston 63 by spring 62, the outside of slow pressure piston 63 be connected to 5 inner wall phase of round tube
Patch, ensure that leakproofness.
The installation steps of the tubular protective case 1 of the utility model are as follows:
Before immersible pump is put into deep-well, first immersible pump is put into inside tubular protective case 1, then closes first automatic bottom cover 42
The bottom end for sealing tubular protective case 1 is closed, then to water is poured into inside tubular protective case 1, makes to keep certain water inside tubular protective case 1
Pressure, closes sealing cover 2 after filling water, keeps sealing inside tubular protective case 1 at this time and has certain hydraulic pressure.By tubular protective case
1 is put into inside deep-well, and during being put into, with the dive of immersible pump, hydraulic pressure is gradually increased in well, and hydraulic pressure is greater than tubular in well
When 1 inside water pressure of protective case and the elastic force summation of spring 62, delay pressure piston 63 gradually to left dislocation, 1 inner space of tubular protective case subtracts
Small, interior hydraulic pressure increases, and 62 forced compression of spring has haved the function that balancing water pressure.After immersible pump reaches extraction place, automatically
Bottom cover 42 automatically opens under the starting of oil cylinder 43, and immersible pump starts to extract gas hydrates.
Preferably, the surface of the 1 energy effective protection immersible pump of tubular protective case of the utility model preserves from, buffer board 8
The impact power after diving is pumped into well is effectively reduced with pressure spring 7, the closing of sealing cover and automatic bottom cover ensure that tubular is protected
1 inner sealing of shell, so that the hydraulic pressure that immersible pump is subject to is reduced, 6 energy active balance hydraulic pressure of hydraulic balance device, to reduce
The submergence pressure of immersible pump, reduces the pressure that tubular protective case 1 is subject to, sand control sieve effectively prevent sandstone soil enter it is latent
Water pump ensure that the degree of purity of the gas hydrates of extraction, also ensure that water pump will not block, support leg 3 can be supported effectively
It tubular protective case 1 and avoids tubular protective case 1 and enters friction during well with the borehole wall, avoid the water inlet of immersible pump from being plugged, mention
High efficiency of drawing water.
Although above having made detailed description to the utility model with generality explanation and specific embodiment,
On the basis of the utility model, it can be made some modifications or improvements, this is apparent to those skilled in the art
's.Therefore, these modifications or improvements on the basis of without departing from the spirit of the present invention, belong to the utility model and want
Seek the range of protection.
