Description

Technical Field

[0001] This utility model relates to the field of coal mining technology, specifically to a connector device for draining water from a gas extraction hole. Background Technology

[0002] Gas drainage boreholes are a safety measure used in coal mine production to eliminate the danger of gas accumulation or potential accumulation by drilling into the coal seam. During the gas drainage process, condensate often forms in the pipeline. If this water is not removed in time, it will block the pipeline, affecting the gas drainage efficiency and the normal operation of the system. Therefore, it is necessary to use appropriate pipelines to drain this condensate in a timely manner. Due to the complexity of the pipelines, appropriate joints are used to connect and transport the pipelines.

[0003] A search revealed an existing patent (publication number: CN20297052U) that discloses a casing connector for gas extraction boreholes, comprising a casing, a core tube, and a receiving tube. One end of the core tube is threaded to the casing, and the other end is spherically hinged to the receiving tube. The other end of the receiving tube is threaded to the adjacent casing. An O-ring is provided at the maximum diameter of the outer spherical connector of the core tube, and symmetrically arranged correction rubber rings are provided at both boundaries of the outer spherical connector. The outer wall of the receiving tube tapers in diameter at both ends, forming a trapezoidal boss in the middle. A groove for inserting rollers is designed at one end of the boss, and three guide rollers are equally spaced within the groove, with the center line of the rollers coinciding with the surface of the boss. This invention has a simple structure, and the connector angle can change with borehole deformation during use. Simultaneously, the guide rollers reduce frictional resistance during casing operation, ensuring the casing can be smoothly lowered to the bottom of the borehole.

[0004] However, the above solution has poor sealing performance, relying on a single sealing ring to seal the pipe and joint, resulting in poor sealing effect. Once the sealing ring ages or deforms excessively, it will cause water leakage and a small amount of condensate leakage, affecting its water discharge effect.

[0005] In view of this, the present invention proposes a connector device for water discharge from a gas extraction hole. Utility Model Content

[0006] This utility model proposes a connector device for draining water from a gas extraction hole, which solves the problem of poor connection sealing in related technologies.

[0007] The technical solution of this utility model is as follows: A connector device for draining water from a gas extraction hole includes a connector body; internal threads symmetrically formed on the inner wall of the connector body; a connecting pipe disposed on one side of the inner wall of the connector body, wherein the surface of the connecting pipe and the internal threads form a threaded engagement structure; sealing components symmetrically assembled on the inner wall of the connector body, wherein the sealing components are used to improve the sealing performance between the connecting pipe and the inner wall of the connector body; and clamping components symmetrically assembled on both sides of the connector body, wherein the clamping components are used to improve the firmness and stability of the threaded installation of the connecting pipe and the connector body.

[0008] The sealing assembly includes: a sealing gasket symmetrically fixedly connected to the inner wall of the connector body; a cavity formed inside the sealing gasket; a sealing airbag symmetrically fixedly connected to the inner wall of the connector body, the interior of the sealing airbag being connected to the interior of the cavity at equal angles via a conduit; and a sealing ring symmetrically fixedly connected to the inner wall of the connector body.

[0009] Preferably, the sealing ring is O-shaped, and one side of the inner wall of the sealing ring is inclined.

[0010] Preferably, the inner wall of the cavity is fixedly connected with an elastic block at an equal angle, and the middle position of the surface of the elastic block is concave.

[0011] Preferably, the clamping assembly includes: a fixed seat symmetrically fixedly connected to both sides of the connector body, with a reserved groove on one side of the top of the fixed seat; a rotating handle rotatably connected to the bottom wall of the reserved groove, with a threaded rod rotatably connected to one side of the bottom wall of the fixed seat, the top of the threaded rod being fixedly connected to the bottom of the rotating handle; a threaded plate threadedly connected to the surface of the threaded rod; and a connecting block fixedly connected to one side of the bottom of the threaded plate, the bottom of the connecting block extending to the outside of the fixed seat and fixedly connected to a clamping plate, with a rubber block fixedly connected to the bottom of the clamping plate.

[0012] Preferably, the inner wall of the fixed base is provided with a sliding groove, and a slider that slides in cooperation with the inside of the sliding groove is fixedly connected to one side of the threaded plate.

[0013] Preferably, the bottom end of the rubber block is arc-shaped, and the top end of the rubber block is fixedly connected to the bottom end of the pressure plate.

[0014] Preferably, an elastic ring is fixedly connected to the surface of the handle, and the elastic ring is O-shaped.

[0015] Preferably, the surface of the connector body is rotatably connected with balls, which are evenly spaced and distributed at equal angles on the surface of the connector body.

[0016] The beneficial effects of this utility model are as follows:

[0017] In this invention, after the connecting pipe and the connector body are tightened and installed, a sealing ring is used to improve the sealing between the surface of the connecting pipe and the inner wall of the connector body. At the same time, a sealing gasket is used to improve the sealing between one end of the connecting pipe and the inner wall of the sealing component, achieving a second layer of sealing. After the connecting pipe is tightened, the sealing gasket can be squeezed to deliver some air from the cavity to the sealing airbag, causing the sealing airbag to expand and further adhere tightly to the outer surface of the connecting pipe, achieving a third layer of sealing. This also improves the firmness and stability of the tightened installation of the connecting pipe and the inner wall of the connector body. Thus, through multiple seals, an effective seal between the connector body and the connecting pipe is ensured, preventing leakage during water discharge due to damage to a single sealing ring, and ensuring a long-term and good sealing effect for both.

[0018] In this invention, a screwdriver or other tool is used to rotate the handle, which drives the threaded rod to rotate. This causes the threaded plate to slide and the connecting block to descend, which in turn causes the clamping plate and the rubber block to descend until the rubber block is in close contact with the surface of the connecting pipe and deforms. This improves the anti-slip properties of the clamping, thereby further reducing the possibility of loosening of the threads between the connecting pipe and the connector body, and ensuring the firm and stable connection between the connecting pipe and the connector body.

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model. Example

[0027] A preferred embodiment of the gas extraction hole water discharge connector device provided by this utility model is, for example... Figures 1 to 5 As shown: A connector device for draining water from a gas extraction hole includes a connector body 4; internal threads 6 symmetrically formed on the inner wall of the connector body 4; a connecting pipe 5 disposed on one side of the inner wall of the connector body 4, wherein the surface of the connecting pipe 5 and the internal threads 6 form a threaded engagement structure; a sealing component 2 symmetrically assembled on the inner wall of the connector body 4, the sealing component 2 being used to improve the sealing performance between the connecting pipe 5 and the inner wall of the connector body 4; and a clamping component 1 symmetrically assembled on both sides of the connector body 4, the clamping component 1 being used to improve the firmness and stability of the threaded installation of the connecting pipe 5 and the connector body 4.

[0028] The sealing assembly 2 includes: a sealing gasket 202 symmetrically fixedly connected to the inner wall of the connector body 4; a cavity 204 opened inside the sealing gasket 202; a sealing airbag 205 symmetrically fixedly connected to the inner wall of the connector body 4, the interior of the sealing airbag 205 being connected to the interior of the cavity 204 at equal angles through a conduit; and a sealing ring 201 symmetrically fixedly connected to the inner wall of the connector body 4.

[0029] In this embodiment, after the connecting pipe 5 and the connector body 4 are tightened and installed, the sealing ring 201 is used to improve the sealing between the surface of the connecting pipe 5 and the inner wall of the connector body 4. At the same time, the sealing gasket 202 is used to improve the sealing between one end of the connecting pipe 5 and the inner wall of the sealing component 2, thus achieving a second seal. After the connecting pipe 5 is tightened, the sealing gasket 202 can be squeezed to deliver some of the air inside the cavity 204 to the sealing airbag 205, causing the sealing airbag 205 to expand and further adhere tightly to the outer surface of the connecting pipe 5, thus achieving a third seal. This also improves the firmness and stability of the tightened installation of the connecting pipe 5 and the inner wall of the connector body 4.

[0030] In a further preferred embodiment of the present invention, the sealing ring 201 is O-shaped, and one side of the inner wall of the sealing ring 201 is inclined.

[0031] In this embodiment, the use of the beveled sealing ring 201 allows the connecting pipe 5 to be screwed into the connector body 4 more smoothly, and achieves initial installation sealing between the two.

[0032] In a further preferred embodiment of the present invention, an elastic block 203 is fixedly connected to the inner wall of the cavity 204 at equal angles, and the middle position of the surface of the elastic block 203 is concave.

[0033] In this embodiment, the elastic block 203 is used to improve the compressive strength of the cavity 204, so that the cavity 204 can be restored more quickly after the connecting pipe 5 is loosened, which is convenient for the next tightening connection. Example

[0034] Based on Embodiment 1, a preferred embodiment of the gas extraction hole water discharge connector device provided by this utility model is as follows: Figures 1 to 5 As shown: The clamping assembly 1 includes: a fixed seat 101 symmetrically fixedly connected to both sides of the connector body 4, with a reserved groove 102 opened on one side of the top of the fixed seat 101; a rotating handle 110 rotatably connected to the bottom wall of the reserved groove 102, with a threaded rod 109 rotatably connected to one side of the bottom wall of the fixed seat 101, and the top of the threaded rod 109 being fixedly connected to the bottom end of the rotating handle 110; a threaded plate 107 threadedly connected to the surface of the threaded rod 109; a connecting block 106 fixedly connected to one side of the bottom end of the threaded plate 107, with the bottom end of the connecting block 106 extending to the outside of the fixed seat 101 and fixedly connected to a clamping plate 105, and a rubber block 104 fixedly connected to the bottom end of the clamping plate 105.

[0035] In this embodiment, the screwdriver or other tools are used to rotate the handle 110 to drive the threaded rod 109 to rotate. The threaded engagement between the threaded rod 109 and the threaded plate 107 causes the threaded plate 107 to slide and drive the connecting block 106 to descend. This causes the clamping plate 105 and the rubber block 104 to descend until the rubber block 104 is tightly attached to the surface of the connecting pipe 5 and deforms, improving the anti-slip properties of the clamping and further reducing the possibility of loosening of the threads between the connecting pipe 5 and the connector body 4.

[0036] In a further preferred embodiment of the present invention, a groove 103 is provided on the inner wall of the fixed base 101, and a slider 108 that slides and engages with the inside of the groove 103 is fixedly connected to one side of the threaded plate 107.

[0037] In this embodiment, the sliding of the slider 108 and the inside of the groove 103 is used to improve the smoothness of the threaded plate 107 sliding up and down.

[0038] In a further preferred embodiment of the present invention, the bottom end of the rubber block 104 is arc-shaped, and the top end of the rubber block 104 is fixedly connected to the bottom end of the pressing plate 105.

[0039] In this embodiment, an arc-shaped rubber block 104 is used to improve the anti-slip properties of the rubber block 104, which is in close contact with the surface of the connecting pipe 5.

[0040] In a further preferred embodiment of the present invention, an elastic ring 111 is fixedly connected to the surface of the handle 110, and the elastic ring 111 is O-shaped.

[0041] In this embodiment, the O-ring 111 is used to improve the anti-slip properties between the handle 110 and the inner wall of the reserved groove 102, and to prevent the rubber block 104 and the pressure plate 105 from sliding and separating due to loosening of the threads of the handle 110.

[0042] In a further preferred embodiment of the present invention, the surface of the connector body 4 is rotatably connected with balls 3, which are distributed at equal intervals and angles on the surface of the connector body 4.

[0043] In this embodiment, the rotating ball bearing 3 is used to reduce the contact friction between the outer wall of the connector body 4 and the inner wall of the extraction hole.

[0044] The working principle of this utility model is as follows: First, the external thread and internal thread 6 on the surface of the connecting pipe 5 are used to achieve threaded locking between the connector body 4 and the connecting pipe 5. After the connecting pipe 5 and the connector body 4 are tightened, the sealing ring 201 is used to improve the sealing between the surface of the connecting pipe 5 and the inner wall of the connector body 4. At the same time, the sealing gasket 202 is used to improve the sealing between one end of the connecting pipe 5 and the inner wall of the sealing component 2, achieving a second layer of sealing. After the connecting pipe 5 is tightened, the sealing gasket 202 can be squeezed to deliver some air from the cavity 204 to the sealing airbag 205, causing the sealing airbag 205 to expand and further adhere to the outer surface of the connecting pipe 5, achieving a third layer of sealing. This also improves the firmness and stability of the tightened installation between the connecting pipe 5 and the inner wall of the connector body 4.

[0045] Then, by turning the handle 110 with a screwdriver or other tools, the threaded rod 109 is rotated. The threaded engagement between the threaded rod 109 and the threaded plate 107 causes the threaded plate 107 to slide and drive the connecting block 106 to descend. This causes the clamping plate 105 and the rubber block 104 to descend until the rubber block 104 is tightly pressed against the surface of the connecting pipe 5 and deforms, improving the anti-slip properties of the two and further reducing the possibility of loosening of the threads between the connecting pipe 5 and the connector body 4.

[0046] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
