Abstract
Description
Technical Field
[0001] This invention relates to the field of downhole water pumping technology, and more particularly to drilling water pumping devices. Background Technology
[0002] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art.
[0003] During drilling, the drill bit, under the influence of rotation and pressure, gradually penetrates the rock of the formation. As drilling deepens, a vertical wellbore is gradually formed. Once the wellbore penetrates the groundwater layer, groundwater flows into the wellbore along rock fissures and pores under pressure, creating a water level inside the wellbore. Since well casing, pumps, and other related equipment are typically installed after the wellbore is formed, the water inside the wellbore needs to be pumped out beforehand. A common method is to hoist submersible pumps and other equipment into the wellbore. However, when using this method, the pump body is prone to movement underwater due to water flow dynamics or interaction with the well wall. This movement can cause the pump to deviate from its optimal pumping position, reducing pumping efficiency. Furthermore, the pump body is susceptible to collision with the wellbore's inner wall, potentially damaging the equipment. Therefore, designing a pumping device that prevents displacement during underground pumping is a problem that needs to be solved by those skilled in the art. Summary of the Invention

[0031] Please refer to Figures 1-7 The application discloses a drilling water pumping device, which comprises a rope 1 and a machine base 4. One end of the rope 1 is connected with a water pumping assembly 2. In use, a hoisting device is controlled to start, the hoisting device winds and unwinds the rope 1, the water pumping assembly 2 can be lowered into a drilling well or pulled out of the drilling well, and the water pumping assembly 2 is used for pumping water in the drilling well. The hoisting device is common knowledge in the field, and therefore, the specific structure, composition and working principle of the hoisting device are not described in detail.
[0032] In an embodiment, the device further comprises a sleeve assembly 3, the sleeve assembly 3 comprising a plurality of sleeve bodies 31, each two adjacent sleeve bodies 31 being hingedly connected at one side, each sleeve body 31 being configured to be sleeved on the rope 1 and move up and down with the rope 1, and in a normal state, the sleeve bodies 31 are also wound on the moving end of the hoisting device, the base 4 is arranged at the top of the wellbore, and the base 4 is capable of driving the sleeve assembly 3 to move horizontally, each sleeve body 31 is provided with a locking component, the locking component is capable of limiting each sleeve body 31 when each sleeve body 31 is on the same axis, so that the limited sleeve bodies 31 form an integral whole; the moving end of the base 4 is provided with an unlocking assembly 5, the unlocking assembly 5 is capable of triggering each locking component in sequence when the sleeve assembly 3 is retracted upward, so that each sleeve body 31 is released from the limitation and is capable of rotating around the hinge point.
[0033] In a specific implementation, when the hoisting device hoists the pumping assembly 2 into the wellbore, the rope 1 and the sleeve bodies 31 wound on the moving end of the hoisting device are straightened, and in this process, each two adjacent sleeve bodies 31 are locked with each other by the locking component, so that each sleeve body 31 becomes a vertical and non-rotatable cylindrical structure, the rope 1 is arranged in each sleeve body 31, and the bottom of the sleeve assembly 3 abuts against the pumping assembly 2, so that the pumping assembly 2 cannot be deviated, and since the base 4 is capable of driving the sleeve assembly 3 to move horizontally, the horizontal position of the sleeve assembly 3 can be adjusted by the base 4, so that the pumping assembly 2 can be moved to a suitable pumping position for pumping, so as to ensure that the pumping assembly 2 has better efficiency and safety during pumping.
[0034] In addition, when the pumping assembly 2 needs to be retracted, the sleeve assembly 3 is also retracted upward, at this time, each sleeve body 31 drives the locking component to move upward and sequentially contact and trigger the unlocking assembly 5, and the locking component releases the limitation of each sleeve body 31 after being triggered, so that each sleeve body 31 can rotate around the hinge point and be wound on the moving end of the hoisting device with the rope 1.
[0035] In an embodiment, the locking component comprises a L-shaped bolt 6 which is slidably mounted on the top of the corresponding sleeve body 31, the bolt 6 is composed of a vertical part and a horizontal part which is mounted on the bottom of the vertical part, and the side of the vertical part and the horizontal part which are away from each other both extend out of the sleeve body 31, the vertical part and the horizontal part are both capable of moving up and down relative to the sleeve body 31, the bottom of the sleeve body 31 is provided with a positioning slot 32 which corresponds to the bolt 6, and the inside of the sleeve body 31 is further vertically provided with a first spring which is capable of pushing the bolt 6 upward so that the vertical part of the bolt 6 is inserted into the corresponding positioning slot 32 of the sleeve body 31 which is located on the top of the bolt 6; the unlocking assembly 5 comprises a ring body 51 which is mounted on the moving end of the base 4, the ring body 51 is sleeved on the outside of the sleeve assembly 3, and the ring body 51 is provided with an unlocking component which is capable of moving to the side which is close to or away from the bolt 6.
[0036] In a specific implementation, when one of the two adjacent sleeve bodies 31 has been in a vertical state, and the other one is gradually rotated to a vertical state from the hinge, the sleeve body 31 which is located on the top will abut against the bolt 6 on the sleeve body 31 which is located on the bottom, and make the bolt 6 retract into the corresponding sleeve body 31, and when the two sleeve bodies 31 are located on the same axis, the bolt 6 on the sleeve body 31 which is located on the top is aligned with the positioning slot 32 on the sleeve body 31 which is located on the bottom, at this time, the bolt 6 is pushed by the first spring and inserted into the corresponding positioning slot 32, so that the two adjacent sleeve bodies 31 are in a vertical state and fixed, and when a plurality of sleeve bodies 31 are all fixed in the above-mentioned manner, a vertical and non-rotatable cylindrical structure is formed.
[0037] At the same time, the unlocking component has two states which correspond to the movement of the unlocking component to the side which is close to or away from the bolt 6, when the unlocking component moves to the side which is close to the end of the horizontal part which is located outside the sleeve body 31, the sleeve assembly 3 can be retracted upward, at this time, the bolts 6 will be lifted synchronously, the unlocking component will be in contact with the horizontal parts in the lifting process in sequence, and the vertical part of each bolt 6 will retract into the corresponding sleeve body 31 in the lifting process, at this time, the corresponding bolt 6 is released from the limiting of the sleeve body 31 which is located on the top of the bolt 6, so that the sleeve body 31 which is released from the limiting can be rotated.
[0038] In an embodiment, the unlocking component comprises an adjusting platform 52 arranged on the ring body 51, which can be moved to and limited at a side close to or away from the plug 6. In practice, a threaded rod can be arranged on the ring body 51, and the adjusting platform 52 is slidingly connected with the ring body 51 and screw-connected with the threaded rod. Therefore, rotating the threaded rod can drive the adjusting platform 52 to move linearly. When the threaded rod is not moved, the adjusting platform 52 cannot be moved either. The driving mode of the threaded rod is common knowledge in the art, and thus will not be described in detail herein. The abutting plate 53 is slidably arranged in the adjusting platform 52. A second spring with a greater elastic force than the first spring is arranged horizontally in the adjusting platform 52. The second spring can push the abutting plate 53 and move it to the outside of the adjusting platform 52 away from the second spring. The bottom of the abutting plate 53 at the side outside the adjusting platform 52 has a slope.
[0039] In practice, when the adjusting platform 52 is moved to the position where the slope of the abutting plate 53 is at the top of the horizontal part, the adjusting platform 52 is stopped and limited. After the adjustment is completed, the water pumping assembly 2 can be retracted. At this time, the sleeve assembly 3 is also retracted upward, and the plugs 6 on the sleeve bodies 31 are sequentially lifted and contact the slope of the abutting plate 53. At this time, the abutting plate 53 abuts against the horizontal part of the plug 6, so that the plug 6 cannot be moved. At this time, since the corresponding sleeve body 31 is still rising, the plug 6 is retracted into the sleeve body 31. When the plug 6 is retracted into the sleeve body 31 and cannot be moved, the plug 6 is lifted synchronously with the sleeve body 31, thereby reversely pushing the abutting plate 53 to retract into the adjusting platform 52 until the plug 6 completely passes the abutting plate 53. After the plug 6 and the abutting plate 53 are separated, the first spring and the second spring respectively push the plug 6 and the abutting plate 53 to reset.
[0040] In an embodiment, the sleeve body 31 is annular, and the side away from the hinge is open. The sleeve assembly 3 further comprises a plurality of rotatable blocking rings 34 arranged on the inner wall of each sleeve body 31. The blocking ring 34 is annular, and has an opening on the side wall. A coil spring is arranged at the connection between the sleeve body 31 and the blocking ring 34, and is used to drive the blocking ring 34 to rotate to align the opening on the sleeve body 31 with the opening on the blocking ring 34. The top of the sleeve body 31 is vertically arranged with an abutting rod 33. The outer wall of the blocking ring 34 is arranged with an adjusting groove 35 corresponding to the abutting rod 33. The top wall of the blocking ring 34 corresponding to the abutting rod 33 has a slope.
[0041] In the embodiment, when the two adjacent and vertically distributed sleeve bodies 31 are rotated at the hinge to the same axis, the abutting rod 33 on the bottom sleeve body 31 abuts against the inclined surface of the blocking ring 34 on the top sleeve body 31, and drives the blocking ring 34 to rotate to the open position which is staggered with the open position of the sleeve body 31, at this time, the open position of the corresponding sleeve body 31 is blocked, so that the rope 1 cannot exit from the sleeve body 31, thereby ensuring that the structure has good anti-exit performance when pumping. When recovering, the sleeve body 31 is rotated at the hinge, at this time, the abutting rod 33 gradually exits from the corresponding adjusting groove 35, and the corresponding blocking ring 34 is rotated to reset under the driving of the torsional spring, at this time, the blocking ring 34 is rotated to the open position which is aligned with the open position on the sleeve body 31, so that the rope 1 can exit from the sleeve body 31, therefore, the rope 1 and the sleeve assembly 3 can be separated when recovering by using this way, thereby facilitating separate storage.
[0042] In an embodiment, the two sides of the open position of the sleeve body 31 and the blocking ring 34 are both rounded.
[0043] In this way, the rope 1 can be prevented from being scratched when entering or exiting the sleeve body 31.
[0044] In an embodiment, the machine base 4 includes a ring-shaped base body 41, a plurality of ring-shaped support bases 42 are installed on the side wall of the base body 41 in a lifting manner, a gear ring 43 is rotatably installed on the base body 41, a driving assembly 44 for driving the gear ring 43 to rotate is installed on the base body 41, the driving assembly 44 can be an electric motor with a gear, the gear is engaged with the gear ring 43, a linear module 45 is installed on the gear ring 43, a mounting table 46 is arranged at the moving end of the linear module 45, the linear module 45 can drive the mounting table 46 to reciprocate, and the unlocking assembly 5 is installed at the center of the mounting table 46 in a universal rotating manner.
[0045] In the embodiment, the bottom of the support base 42 can be provided with universal wheels, and the support base 42 and the base body 41 can be connected through a lifting module, which can be a hydraulic rod. By adjusting the height of the support base 42, the device can adapt to uneven placement surfaces and be used, and in cooperation with the driving assembly 44, the gear ring 43 and the linear module 45, the unlocking assembly 5 can move horizontally within the range of the base body 41, and drive the sleeve assembly 3 and the pumping assembly 2 to move to a suitable pumping position. Moreover, since the unlocking assembly 5 can rotate universally at the center of the mounting table 46, when the machine base 4 is placed unevenly, the pumping assembly 2 and the sleeve assembly 3 can still make the unlocking assembly 5 vertically downward, so as to ensure its stable pumping.
[0046] In an embodiment, the water pumping assembly 2 comprises a mounting frame 21 connected with the rope 1, a water pumping body 22 is mounted on the side of the mounting frame 21 away from the rope 1, a hose is connected with the water outlet end of the water pumping body 22, the end of the hose away from the water pumping body 22 extends to outside of the shaft, and a filter cover 23 for blocking impurities is mounted on the water inlet end of the water pumping body 22.
