Description

Technical Field

[0001] The invention relates to the technical field of underground water pumping, in particular to a well drilling water pumping device. Background Art

[0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] During the drilling process, the drill bit gradually penetrates the rock of the formation under the action of rotation and pressure. As the drilling goes deeper, a vertical wellbore channel is gradually formed. When the wellbore is formed, once it penetrates the groundwater layer, the groundwater will flow into the wellbore along the rock cracks and pores under the action of the pressure difference, so that the water level is formed inside the wellbore. Since the wellbore usually needs to be installed with well wall pipes, pumps and other related equipment after it is formed, it is necessary to drain the water in the wellbore in advance. The more common pumping method is generally to lift the submersible pump and other related equipment into the wellbore for pumping. However, when pumping water in this way, the pump body is easily moved underwater due to the water flow force or the interaction with the well wall. After the pump body moves, it is easy to deviate from the optimal pumping position, resulting in reduced pumping efficiency. At the same time, the pump body is easy to collide with the inner wall of the wellbore and damage the equipment. Therefore, how to design a pumping device that can prevent its displacement when pumping water underground has become a problem that people in this field need to solve. Summary of the invention

[0004] The purpose of the present invention is to provide a drilling pumping device to address the above-mentioned shortcomings and prevent deviation when pumping water underground to ensure pumping efficiency and safety.

[0010] The unlocking assembly is arranged at the moving end of the machine base. The unlocking assembly can trigger each locking component in sequence when the sleeve assembly is retracted upward, so that each sleeve body is released from the limit and can rotate around the hinge point.

[0011] Further, the locking component includes an L-shaped latch, which is slidably arranged at the top of the corresponding sleeve body, and the latch is composed of a vertical portion and a transverse portion arranged at the bottom of the vertical portion, and the sides of the vertical portion and the transverse portion that are away from each other both extend outside the sleeve body, and the vertical portion and the transverse portion can both move up and down relative to the sleeve body, and the bottom of the sleeve body is provided with a positioning groove corresponding to the latch, and the inside of the sleeve body is further provided with a first spring, and the first spring can push the latch upward so that the vertical portion of the latch is inserted into the corresponding positioning groove of the sleeve body located at the top thereof;

[0012] The unlocking assembly includes a ring body arranged at the moving end of the machine base, the ring body is sleeved outside the sleeve assembly, and an unlocking component is arranged on the ring body. The unlocking component can move to the side close to or away from the pin, and when the sleeve assembly is retracted upward, the pins will rise synchronously. When the unlocking component moves to the end where the blocking horizontal part is located outside the sleeve body, it can contact the rising horizontal parts and retract the vertical part of each pin into the corresponding rising sleeve body.

[0013] Furthermore, the unlocking component includes an adjusting platform arranged on the ring body, the adjusting platform can move and limit to a side close to or away from the latch, a resistance plate is slidably arranged inside the adjusting platform, a second spring with a greater elastic force than the first spring is arranged inside the adjusting platform, the second spring can push the resistance plate and move it away from the side of the second spring to the outside of the adjusting platform, and the bottom of the resistance plate located on the side outside the adjusting platform has an inclined surface.

[0014] Furthermore, the sleeve body is annular and has an open side away from its hinge.

[0019] In the present invention, when the lifting equipment lifts the pumping assembly into the wellbore, the rope and casing body wound on the moving end of the lifting equipment are straightened. During this process, every two adjacent casing bodies are locked with each other by a locking component, so that each casing body becomes a vertical and non-rotatable cylindrical structure. The rope is passed through each casing body, and the bottom of the casing assembly is against the pumping assembly, so that the pumping assembly cannot be offset. Since the machine base can drive the casing assembly to move horizontally, the horizontal position of the casing assembly can be adjusted by the machine base, so that the pumping assembly can be moved to a suitable pumping position to pump water, thereby ensuring that the pumping assembly has good efficiency and safety when pumping water.

[0020] In the present invention, when the pumping assembly needs to be folded up, the sleeve assembly will also be retracted upward. At this time, each sleeve body drives the locking component to move upward, and contacts the unlocking component in turn and is triggered. After being triggered, the locking component will release the limit on the sleeve body, so that the sleeve body can rotate around its hinge point and be wound around the moving end of the lifting equipment together with the rope, which is also convenient for recycling.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-7 The present invention discloses a drilling water pumping device, including a rope 1 and a machine base 4. One end of the rope 1 is connected to a water pumping assembly 2. When in use, the lifting device is controlled to start, and the rope 1 is retracted to lower the water pumping assembly 2 into the well, or pull up the water pumping assembly 2 in the well. The water pumping assembly 2 is used to extract water from the well. The lifting device mentioned above is common knowledge in the field, so the specific structural composition and working principle will not be described in detail in this article.

[0032] In one embodiment, the device also includes a casing assembly 3, which includes a plurality of casing bodies 31, one side of each adjacent casing bodies 31 is hingedly connected, and each casing body 31 is used to be sleeved on the rope 1 and move up and down with the rope 1. Under normal conditions, the casing body 31 is also wound and arranged at the moving end of the lifting equipment. The machine base 4 is arranged at the top of the wellbore, and the machine base 4 can drive the casing assembly 3 to move horizontally. A locking component is arranged on each casing body 31, and the locking component can limit each casing body 31 when each casing body 31 is on the same axis, so that each casing body 31 that is limited forms a whole; an unlocking component 5 is arranged at the moving end of the machine base 4, and the unlocking component 5 can trigger each locking component in turn when the casing assembly 3 is retracted upward, so that each casing body 31 is released from the limit and can rotate around the hinge point as the center.

[0033] In a specific implementation, when the lifting equipment lifts the pumping assembly 2 into the wellbore, the rope 1 and the casing body 31 wound on the moving end of the lifting equipment are straightened. During this process, every two adjacent casing bodies 31 are locked with each other through a locking component, so that each casing body 31 becomes a vertical and non-rotatable cylindrical structure. The rope 1 is inserted into each casing body 31, and the bottom of the casing assembly 3 is against the pumping assembly 2, so that the pumping assembly 2 cannot be offset. Since the machine base 4 can drive the casing assembly 3 to move horizontally, the horizontal position of the casing assembly 3 can be adjusted by the machine base 4, so that the pumping assembly 2 can be moved to a suitable pumping position for pumping water, thereby ensuring that the pumping assembly 2 has good efficiency and safety when pumping water.

[0034] In addition, when the pumping assembly 2 needs to be folded up, the sleeve assembly 3 will also be retracted upward. At this time, each sleeve body 31 drives the locking component to move upward, and contacts the unlocking assembly 5 in turn and is triggered. After being triggered, the locking component will release the limit on the sleeve body 31, so that the sleeve body 31 can rotate around its hinge point and be wound around the moving end of the lifting equipment together with the rope 1.

[0035] In one embodiment, the locking component includes an L-shaped latch 6, which can be slidably installed on the top of the corresponding sleeve body 31 up and down. The latch 6 is composed of a vertical portion and a transverse portion installed at the bottom of the vertical portion, and the sides of the vertical portion and the transverse portion that are away from each other extend to the outside of the sleeve body 31. The vertical portion and the transverse portion can both move up and down relative to the sleeve body 31. A positioning groove 32 corresponding to the latch 6 is provided at the bottom of the sleeve body 31. A first spring is also vertically installed inside the sleeve body 31. The first spring can push the latch 6 upward so that the vertical portion of the latch 6 is inserted into the corresponding positioning groove 32 of the sleeve body 31 located at the top thereof; the unlocking component 5 includes a ring body 51 installed at the moving end of the machine base 4, the ring body 51 is sleeved outside the sleeve assembly 3, and an unlocking component is provided on the ring body 51, which can move toward or away from the side of the latch 6.

[0036] In a specific implementation, when one of the two adjacent sleeve bodies 31 is in a vertical state and the other gradually rotates to a vertical state from the hinge, the sleeve body 31 at the top will resist the latch 6 on the sleeve body 31 at the bottom, and the latch 6 will be retracted into the corresponding sleeve body 31. When the two sleeve bodies 31 are located on the same axis, the latch 6 on the top sleeve body 31 is aligned with the positioning groove 32 on the bottom sleeve body 31. At this time, the latch 6 is pushed by the first spring and inserted into the corresponding positioning groove 32, so that the two adjacent sleeve bodies 31 are fixed in a vertical state. When multiple sleeve bodies 31 are fixed in the above manner, a vertical and non-rotatable cylindrical structure is formed.

[0037] At the same time, the unlocking component has two states, corresponding to the side where it moves closer to or farther away from the latch 6. When the unlocking component moves to the end where the blocking lateral part is located outside the sleeve body 31, the sleeve assembly 3 can be retracted upward. At this time, each latch 6 will rise synchronously, and the unlocking component will contact the rising lateral parts in turn, and retract the vertical part of each latch 6 into the corresponding sleeve body 31 that is rising. At this time, the corresponding latch 6 releases the limit on the sleeve body 31 located at its top, so that the sleeve body 31 can rotate after the limit is released.

[0038] In one embodiment, the unlocking component includes an adjusting platform 52 arranged on the ring body 51, and the adjusting platform 52 can be moved and limited to a side close to or away from the latch 6. In actual circumstances, a threaded rod can be arranged on the ring body 51, and the adjusting platform 52 is slidably connected to the ring body 51 and is threadedly engaged with the threaded rod. Therefore, rotating the threaded rod can drive the adjusting platform 52 to move linearly. When the threaded rod is stationary, the adjusting platform 52 cannot move either. The threaded rod driving method is common knowledge in the field, so it will not be described in detail in this article; a resistance plate 53 is slidably installed in the adjusting platform 52, and a second spring with a greater elastic force than the first spring is laterally installed inside the adjusting platform 52. The second spring can push the resistance plate 53 and move it away from the second spring to the outside of the adjusting platform 52, and the resistance plate 53 has an inclined surface at the bottom of the outer side of the adjusting platform 52.

[0039] When the adjusting platform 52 moves to the point where the inclined surface of the abutment plate 53 is located at the top of the transverse portion, the adjusting platform 52 stops and is limited. After the adjustment is completed, the pumping assembly 2 can be retracted. At this time, the sleeve assembly 3 will also be retracted upward. The latches 6 on each sleeve body 31 rise in sequence and contact the inclined surface of the abutment plate 53. At this time, the abutment plate 53 will abut the transverse portion of the latch 6, making it impossible for the latch 6 to move. At this time, since the corresponding sleeve body 31 is still rising, the latch 6 will be retracted into the sleeve body 31. When the latch 6 is retracted into the sleeve body 31 and cannot move, the latch 6 will rise synchronously with the sleeve body 31, thereby pushing the abutment plate 53 in the opposite direction to retract it into the adjusting platform 52 until the latch 6 completely passes over the abutment plate 53. After they are separated from each other, the first spring and the second spring respectively push the latch 6 and the abutment plate 53 to reset them.

[0040] In one embodiment, the sleeve body 31 is annular and has an open side away from its hinge. The sleeve assembly 3 also includes a plurality of blocking rings 34 rotatably mounted on the inner wall of each sleeve body 31. The blocking ring 34 is annular and has an opening on its side wall. A coil spring is installed at the connection between the sleeve body 31 and the blocking ring 34. The coil spring is used to drive the blocking ring 34 to rotate until its opening is aligned with the opening on the sleeve body 31. A resistance rod 33 is vertically installed on the top of the sleeve body 31. An adjustment groove 35 corresponding to the resistance rod 33 is opened on the outer wall of the blocking ring 34, and the blocking ring 34 has an inclined surface at the top wall corresponding to the resistance rod 33.

[0041] In a specific implementation, when two adjacent and upper and lower sleeve bodies 31 rotate from their hinges to the same axis, the abutment rod 33 on the bottom sleeve body 31 will abut the inclined surface of the blocking ring 34 on the top sleeve body 31, and drive the blocking ring 34 to rotate until its opening is staggered with the opening of the sleeve body 31. At this time, the opening of the corresponding sleeve body 31 is blocked, so that the rope 1 cannot leave the sleeve body 31, thereby ensuring that the structure has good anti-slip properties when pumping water; when recovering, the sleeve body 31 rotates from its hinge, at which time the abutment rod 33 gradually leaves the corresponding adjustment groove 35, and the corresponding blocking ring 34 rotates and resets under the drive of the torsion spring, at which time the blocking ring 34 rotates until its opening is aligned with the opening on the sleeve body 31, so that the rope 1 can leave the sleeve body 31. Therefore, this method can separate the rope 1 and the sleeve assembly 3 when they are recovered, thereby facilitating separate storage.

[0042] In one embodiment, both sides of the openings of the sleeve body 31 and the blocking ring 34 are rounded.

[0043] Such a design can prevent the rope 1 from being scratched when entering into the sleeve body 31 or leaving from the sleeve body 31 .

[0044] In one embodiment, the base 4 includes an annular base body 41, and a plurality of annularly distributed support bases 42 are installed on the side wall of the base body 41 in a liftable manner. A ring gear 43 is rotatably installed on the base body 41, and a driving component 44 for driving the ring gear 43 to rotate is installed on the base body 41. The driving component 44 can be a motor with gears, and the gears are meshed with the ring gear 43. A linear module 45 is installed on the ring gear 43, and a mounting table 46 is provided at the moving end of the linear module 45. The linear module 45 can drive the mounting table 46 to reciprocate, and the unlocking component 5 can be universally rotatably installed at the center of the mounting table 46.

[0045] In a specific implementation, a universal wheel can be provided at the bottom of the support seat 42, and the support seat 42 and the seat body 41 can be connected through a lifting module, which can be a hydraulic rod. By adjusting the height of the support seat 42, the device can adapt to uneven placement surfaces and be used, and in conjunction with the drive assembly 44, the ring gear 43 and the linear module 45, the unlocking assembly 5 can be horizontally moved within the range of the seat body 41, and drive the sleeve assembly 3 and the pumping assembly 2 to move to a suitable pumping location; and, since the unlocking assembly 5 can be universally rotated at the center of the mounting platform 46, when the base 4 is unevenly placed, the pumping assembly 2 and the sleeve assembly 3 can still make the unlocking assembly 5 face vertically downward to ensure stable pumping.

[0046] In one embodiment, the pumping assembly 2 includes a mounting frame 21 connected to the rope 1, and a pump body 22 is installed on the side of the mounting frame 21 away from the rope 1. A hose is connected to the water outlet end of the pump body 22, and the end of the hose away from the pump body 22 extends outside the wellbore. A filter cover 23 for blocking impurities is installed at the water inlet end of the pump body 22.

[0047] With such a design, when the water pump body 22 is started, it can cooperate with the hose to pump out the water in the wellbore, and the setting of the filter cover 23 can prevent impurities from entering the water pump body 22 to ensure the safe operation of the water pump body 22; in addition, the casing body 31 located at the bottom can be detachably installed on the mounting frame 21, and can be fixed by bolts after connection, and can further prevent the displacement of the water pump assembly 2 when they are connected to each other.

[0048] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0049] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0050] In addition, "plurality" means two or more.
