Description

Technical Field

[0001] This invention relates to the field of well drilling connector technology, and in particular to a quick-assembly and anti-detachment well drilling connector. Background Technology

[0002] As an important and simple water intake facility, a well typically consists of a pump, a hose, a wellhead fitting (lower fitting), and an upper fitting. The pump is installed inside the well, and its outlet is connected to the wellhead fitting (lower fitting) via a hose. The wellhead fitting secures the hose to the hose with clamps. The upper fitting is installed above the lower fitting. The current connection between the upper fitting and the lower fitting primarily uses a flange and bolt fastening structure. The specific flange connection method is as follows: a wellhead seat with a flange is installed at the lower end of the upper fitting, and the wellhead fitting also has a corresponding flange. During installation, the flange of the upper fitting needs to be aligned with the flange of the wellhead fitting. Then, tools (such as a wrench) are used to pass multiple bolts (usually 3-6) through the corresponding bolt holes of the two flanges, and the nuts are tightened one by one for fixation. The disassembly process is the reverse, requiring the nuts and bolts to be loosened and removed one by one.

[0003] This traditional bolt-fastening connection method requires aligning bolt holes, inserting bolts, and tightening or loosening nuts one by one for installation and disassembly. This process is time-consuming and involves many steps. Especially in confined spaces, poor lighting, or situations requiring frequent maintenance, it greatly reduces work efficiency and increases labor intensity. It also has poor adaptability to aging wellheads. Water wells are usually exposed to the outdoor environment for a long time, and the wellhead flanges and bolt holes are easily affected by rainwater erosion, siltation, and rust. For some aging wellheads, the bolt holes often suffer from severe rust, deformation, or even blockage. This makes it difficult for bolts to pass through the bolt holes smoothly. It requires a lot of time and effort to clean rust, enlarge the holes, or forcibly hammer the bolts to barely insert them. The process is extremely difficult and can easily damage the threads or bolt holes. Furthermore, if the tools are lost or the sizes are incompatible, effective operation will be impossible, and there is a risk of the bolts falling out. Summary of the Invention

[0004] This invention provides an automatically positioned, quick-assembly and anti-detachment water well connector, thereby solving the problems of cumbersome installation process and harsh installation conditions of existing upper connectors.

[0005] The technical solution is: a quick-release, anti-detachment water well connector, comprising an upper connector, which is installed on a lower connector. A hose is installed below the lower connector via a clamp. The upper connector is fixedly connected to mounting plates that are evenly spaced circumferentially. A rotating plate is hinged to the mounting plates. A torsion spring is provided at the hinge point between the rotating plate and the mounting plate. The rotating plate is provided with a connecting frame. A pressing block is rotatably connected to the connecting frame. The pressing block is used to press the lower connector. A rotating handle is fixedly connected to the pressing block.

[0006] Furthermore, the cross-sectional shape of the extrusion block is an eccentric circle.

[0007] Furthermore, the rotating plate is fixedly connected to a limiting frame perpendicular to it, the limiting frame is slidably connected to a T-shaped plate, and a spring is fixedly connected between the T-shaped plate and the adjacent limiting frame. The upper connector is slidably connected to top plates that are evenly spaced in the circumferential direction, and the top plates are used to press the adjacent T-shaped plates.

[0008] Furthermore, the top plates, which are circumferentially spaced, are slidably connected to a sealing ring located between the upper connector and the lower connector. The lower side of the upper connector is provided with an annular groove for placing the sealing ring. The thickness of the sealing ring is greater than the depth of the annular groove of the upper connector. The top plate is fixedly connected to a limiting block, which is used to limit the adjacent top plates to the upper connector.

[0009] Furthermore, the top plate is L-shaped, and the top plates, which are circumferentially evenly distributed, together serve to limit the sealing ring.

[0010] Furthermore, the upper connector is slidably connected to a sliding sleeve, and the sliding sleeve is fixedly connected to guide blocks that are circumferentially evenly distributed. The guide blocks are slidably connected to the adjacent top plate, and the guide blocks are used to press the adjacent T-shaped plates.

[0011] Furthermore, a positioning cylinder is fixedly connected inside the upper connector, and the positioning cylinder is used to align the positioning cylinder with the center of gravity axis of the lower connector.

[0012] Furthermore, the diameter of the lower part of the positioning cylinder gradually decreases from top to bottom.

[0013] Furthermore, the positioning cylinder is provided with circumferentially spaced guide grooves.

[0014] Furthermore, the connecting frame is slidably connected to the adjacent rotating plate, and the rotating plate is threadedly connected to a threaded rod that is rotatably connected to the connecting frame.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: The present invention uses three rotating handles and their compression blocks to press down and rotate the upper connector, quickly fixing it close to the lower connector and preventing it from falling off. The sealing ring quickly seals the upper and lower connectors. The three compression blocks ensure that the force on the periphery of the upper connector is evenly downward, guaranteeing alignment between the upper and lower connectors while the sealing ring is evenly compressed, increasing the sealing performance between them. Pulling the sliding sleeve moves the guide block upward, and the torque release of the torsion spring on the rotating plate quickly releases the fixation between the upper and lower connectors, eliminating the need for operators to loosen six bolts sequentially. The positioning cylinder automatically aligns the central axes of the upper and lower connectors, and the guide groove of the positioning cylinder reduces resistance, ensuring the sealing performance between the upper and lower connectors. The threaded rod adjusts the distance between the connecting frame and the adjacent rotating plate to accommodate lower connectors with different shoulder thicknesses, improving the applicability of the present invention.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Example 1

[0024] A quick-release, anti-detachment well drilling connector, such as Figures 1-5As shown, it includes an upper connector 1, which is mounted on a lower connector 101 (wellhead pipe connector). Shoulders are provided on the lower side of the upper connector 1 and the upper side of the lower connector 101. A hose 102 is installed below the lower connector 101 via a clamp 103. The hose 102 is used to transport water from the well. Three sets of mounting plates 2, evenly spaced circumferentially distributed, are fixedly connected to the upper side of the shoulder of the upper connector 1. Each set of mounting plates 2 contains two symmetrically distributed plates. A vertically placed rotating plate 3 is hinged between the two mounting plates 2 in the same set. A torsion spring is provided at the hinge point between the rotating plate 3 and the mounting plate 2. A connecting frame 4 is provided on the lower side of the rotating plate 3 (in this embodiment, the rotating plate 3 and the connecting frame 4 are fixedly connected, limited to this embodiment). The frame 4 is L-shaped. The lower side of the connecting frame 4 is located below the shoulder of the lower connector 101, and the upper part of the connecting frame 4 is located around the shoulder of the lower connector 101. The connecting frame 4 is rotatably connected to the pressing block 5. The pressing block 5 is used to press the lower connector 101. There is friction between the pressing block 5 and the adjacent connecting frame 4. Without external force, the pressing block 5 will not rotate relative to the connecting frame 4. The cross-sectional shape of the pressing block 5 is an eccentric circle. The pressing block 5 is fixedly connected to the rotating handle 501. Pressing down and rotating the three rotating handles 501 and the pressing block 5 on them causes the upper connector 1 to press the sealing ring 9 and move closer to the lower connector 101. The sealing ring 9 quickly seals the upper connector 1 and the lower connector 101, and at the same time, the upper connector 1 and the lower connector 101 are fixed.

[0025] like Figures 2-5 As shown, a limiting frame 6 perpendicular to the rotating plate 3 is fixedly connected to the rotating plate 3. The limiting frame 6 is provided with a T-shaped groove. A T-shaped plate 7 is slidably connected in the T-shaped groove of the limiting frame 6. A spring is fixedly connected between the T-shaped plate 7 and the adjacent limiting frame 6. Three top plates 8 are circumferentially and equidistantly distributed through the shoulder of the upper connector 1. The top plates 8 are used to press the adjacent T-shaped plates 7. The lower sides of the three top plates 8 are slidably connected to a sealing ring 9 located between the upper connector 1 and the lower connector 101. The thickness of the sealing ring 9 is greater than the depth of the annular groove of the upper connector 1. Limiting blocks 801 are fixedly connected to both sides of the top plates 8. The limiting blocks 801 are used to limit the adjacent top plates 8 to the upper connector 1. The top plates 8 are L-shaped. The three top plates 8 are used together to limit the sealing ring 9.

[0026] like Figures 1-3 and Figure 5 As shown, the upper connector 1 is slidably connected to a sliding sleeve 10, and the sliding sleeve 10 is fixedly connected to three sets of guide blocks 11 that are circumferentially and equally spaced. Each set of guide blocks 11 consists of two symmetrically distributed blocks. The guide blocks 11 are slidably connected to the adjacent top plate 8. The guide blocks 11 are provided with inclined surfaces for pressing the adjacent T-shaped plates 7. The upper connector 1 and the lower connector 101 can be quickly unlocked by directly pulling up the sliding sleeve 10.

[0027] When installing the existing water drilling well connector at the wellhead, the through hole of the water drilling well connector needs to be aligned with the through hole of the wellhead, and bolts need to be inserted into it. Then, the operator needs to fix six bolts in sequence. This process is cumbersome and cannot fix the water drilling well connector in a short time. When removing the water drilling well connector, the operator also needs to loosen six bolts in sequence before removing it.

[0028] In the initial state, such as Figure 5 As shown, the torsion spring between the mounting plate 2 and the rotating plate 3 is in normal condition. The sealing ring 9 is limited by the lower side of the three top plates 8 and cannot move downward. The limiting blocks 801 on the three top plates 8 are in contact with the shoulder of the upper connector 1 and cannot move downward. Taking the T-shaped plate 7 on the right as an example, the left side of the T-shaped plate 7 is not in contact with the inclined surface of the guide block 11. The diameter of the inscribed circle between the three extrusion blocks 5 is greater than or equal to the diameter of the shoulder of the lower connector 101. The friction between the extrusion block 5 and the adjacent connecting frame 4 keeps the rotating handle 501 perpendicular to the adjacent rotating plate 3. When it is necessary to install the upper connector 1 on the lower connector 101, the operator needs to move the upper connector 1 directly above the lower connector 101 and move it downward slowly. The three extrusion blocks 5 move downward from the outside of the shoulder of the lower connector 101. When the state between the upper connector 1 and the lower connector 101 is as follows... Figure 5 As shown, the operator continues to move the upper connector 1 downwards. When the three top plates 8 contact the upper side of the shoulder of the lower connector 101, the lower side of the sealing ring 9 contacts the upper side of the shoulder of the lower connector 101. At this time, the three top plates 8 and the sealing ring 9 are limited by the shoulder of the lower connector 101 and cannot move downwards.

[0029] As the upper connector 1 continues to move downwards, the sealing ring 9 gradually positions itself within the annular groove of the upper connector 1. During this downward movement, taking the right-side T-shaped plate 7 as an example, the left side of the T-shaped plate 7, limited by the top plate 8, begins to rotate clockwise around the upper side of the rotating plate 3. The torsion spring on the rotating plate 3 stores energy, causing the T-shaped plate 7 to drive the limiting frame 6, rotating plate 3, connecting frame 4, pressing block 5, and rotating handle 501 to rotate clockwise around the upper side of the rotating plate 3. The pressing block 5 gradually positions itself on the right side below the shoulder of the lower connector 101. Before the limiting frame 6 and the T-shaped plate 7 are both in a horizontal position, the upper side of the sealing ring 9 fills the annular groove of the upper connector 1. Because the thickness of the sealing ring 9 is greater than the depth of the annular groove of the upper connector 1, the shoulder of the upper connector 1 does not align with the lower connector 101. The shoulder of the joint contacts the lower connector 101. Then, the operator simultaneously presses down on all three rotating handles 501. Taking the right rotating handle 501 as an example, the rotating handle 501 drives the pressing block 5 to rotate clockwise around the left side of the connecting frame 4. During this clockwise rotation, the protrusion of the pressing block 5 gradually contacts and presses against the lower side of the shoulder of the lower connector 101. The pressing block 5, through the connecting frame 4, rotating plate 3, and mounting plate 2, pulls the upper connector 1 downwards, causing it to gradually approach the lower connector 101 and press against the sealing ring 9. The pressure between the sealing ring 9 and the upper and lower connectors 101 increases, enhancing the sealing performance between the sealing ring 9 and the upper and lower connectors 101. When the rotating handle 501 is rotated to the vertical position, the state is as follows... Figure 2 As shown, the sealing ring 9 is fully inserted into the annular groove of the upper connector 1, and the fixing process between the upper connector 1 and the lower connector 101 is completed.

[0030] By pressing down and rotating the three rotating handles 501 and the pressing blocks 5 thereon, the upper connector 1 is pressed against the sealing ring 9 and brought closer to the lower connector 101. The sealing ring 9 quickly seals the upper connector 1 and the lower connector 101, and at the same time, the upper connector 1 and the lower connector 101 are fixed. The three pressing blocks 5 make the force on the periphery of the upper connector 1 evenly downward, ensuring that the upper connector 1 and the lower connector 101 are aligned while the sealing ring 9 is evenly compressed, increasing the sealing performance between the upper connector 1 and the lower connector 101. If the existing upper connector 1 is pressed down evenly, the operator needs to tighten six bolts at the same time, which is cumbersome. If the bolts are tightened sequentially, the pressure on one side of the sealing ring 9 will be too high or too low, affecting the sealing performance between the upper connector 1 and the lower connector 101. Moreover, the installation method of the upper connector 1 does not require the bolt holes of the lower connector 101 to participate. Therefore, even if the bolt holes of the lower connector 101 are blocked, the upper connector 1 can still be fixed on the lower connector 101.

[0031] When it is necessary to quickly remove the upper connector 1 from the lower connector 101, the operator pulls the sliding sleeve 10 and the six guide blocks 11 upwards. Taking the two guide blocks 11 on the right as an example, the two guide blocks 11 move upwards along the front and rear sides of the top plate 8. When the inclined surfaces of the two guide blocks 11 are in contact with the left side of the T-shaped plate 7, the two guide blocks 11 continue to move upwards and squeeze the T-shaped plate 7 to move to the right, and the spring on the limit frame 6 is compressed.

[0032] When the left side of the T-shaped plate 7 is flush with the right side of the top plate 8, the T-shaped plate 7 is no longer squeezed by the two guide blocks 11. At this time, the left side of the T-shaped plate 7 is no longer limited by the top plate 8. The release of the elastic force of the sealing ring 9 causes the upper connector 1 to move upward. At the same time, the release of the torque on the rotating plate 3 causes the rotating plate 3 to rotate counterclockwise around its upper side. The rotating plate 3 drives the connecting frame 4, the pressing block 5, and the rotating handle 501 to rotate counterclockwise. At the same time, the rotating plate 3 drives the limiting frame 6 and the T-shaped plate 7 to rotate counterclockwise. The pressing block 5 is no longer located in the position of the top plate 8. Directly below the shoulder of the lower connector 101, during the counterclockwise rotation of the limiting frame 6 and the T-shaped plate 7, the spring force on the limiting frame 6 is released, causing the T-shaped plate 7 to move to the left, thus releasing the fixation between the upper connector 1 and the lower connector 101. Subsequently, the operator removes the upper connector 1, and through the sliding sleeve 10, drives the guide block 11 to move upward. With the release of the torsion spring on the rotating plate 3, the fixation between the upper connector 1 and the lower connector 101 is quickly released without the need for the operator to loosen the six bolts in sequence.

[0033] Example 2

[0034] Based on Example 1, a quick-release, anti-detachment water well connector is provided, such as... Figure 2 , Figure 3 and Figure 5 As shown, a positioning cylinder 13 is fixedly connected inside the upper connector 1. The positioning cylinder 13 is used to make the center axis of the positioning cylinder 13 coincide with that of the lower connector 101. The diameter of the lower part of the positioning cylinder 13 gradually decreases from top to bottom. The diameter of the rest of the positioning cylinder 13 is equal to the inner diameter of the upper connector 1. The positioning cylinder 13 is provided with circumferentially evenly distributed guide grooves.

[0035] During the alignment of the upper connector 1 and the lower connector 101, the operator first inserts the lower side of the positioning cylinder 13 into the lower connector 101 via the upper connector 1. If the central axes of the upper connector 1 and the lower connector 101 are not aligned during this process, the lower part of the positioning cylinder 13 will move the positioning cylinder 13 and the upper connector 1, causing the central axis of the positioning cylinder 13 to slowly align with the central axis of the lower connector 101. When the positioning cylinder 13 and the lower connector 101 are in the correct state... Figure 5As shown, the upper connector 1 and the lower connector 101 are aligned. During the operation of the upper connector 1, water in the well enters the upper connector 1 through the lower connector 101. When the water flows through the positioning cylinder 13, the water between the lower outer side of the positioning cylinder 13 and the inner wall of the lower connector 101 will enter the positioning cylinder 13 through the guide groove of the positioning cylinder 13, reducing the resistance on the positioning cylinder 13, mitigating the impact force of the water on the positioning cylinder 13, the lower connector 101 and the upper connector 1, and ensuring the sealing between the positioning cylinder 13 and the upper connector 1 and the lower connector 101.

[0036] Example 3

[0037] Based on Example 2, a quick-release, anti-detachment water well connector is provided, such as... Figure 3 and Figure 4 As shown, the connecting frame 4 is slidably connected to the adjacent rotating plate 3. The rotating plate 3 is threadedly connected to a threaded rod 14 that is rotatably connected to the connecting frame 4. The operator can rotate the threaded rod 14 to adjust the distance between the connecting frame 4 and the adjacent rotating plate 3.

[0038] When the shoulder thickness of different lower connectors 101 is different, the operator rotates the threaded rod 14 according to the actual thickness of the shoulder of the lower connector 101, thereby adjusting the distance between the connecting frame 4 and the adjacent rotating plate 3 to adapt to lower connectors 101 with different shoulder thicknesses and improve the applicability of the upper connector 1.

They should not be construed as limiting the scope of protection of the present invention.
