Description

Technical Field

[0001] This invention relates to the field of gas detector installation technology, specifically to a detachable pipeline installation structure and a gas detector containing the structure. Background Technology

[0002] Traditional gas detectors are often installed on pipelines using flange bolts or welding, requiring specialized tools and being time-consuming and labor-intensive to install and remove. Maintenance requires stopping the machine for disassembly, affecting production continuity. Existing quick-release structures often suffer from inaccurate positioning and unreliability. After installation, the detector is prone to displacement or loosening due to pipeline vibration, leading to gas leaks or distorted detection data. Therefore, since the existing requirements are not met, we propose a detachable pipeline installation structure and a gas detector containing this structure. Summary of the Invention

[0003] Therefore, the present invention provides a detachable pipe installation structure to solve the above-mentioned problems in the prior art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: According to a first aspect of the present invention, a detachable pipe installation structure includes a pipe, a gas detector, and a detachable installation structure disposed between the two, wherein the pipe has a detection hole and a fixed protrusion is fixed on the outer side of the top of the hole; The detachable mounting structure includes: A clamp consisting of two retaining rings fixed by bolts, with a groove on the top of the inner wall of the clamp matching the protrusion; The connection mechanism installed between the top of the clamp and the gas detector includes: The mounting base is fixed to the top of the clamp, and the lifting plate is slidably connected to its inner wall; The outer side of the lifting plate is equipped with a ring array of hooks that rotate via a mounting shaft, and a spiral spring drives the hooks to open outwards. The lifting plate is slidably connected to the vertical groove of the mounting base via a guide block. The inner side of the guide block is slidably connected to the outer wall of the guide rod. A thrust spring is installed between the bottom end of the guide block and the bottom end of the inner wall of the vertical groove. The guide rod and the thrust spring provide the upward restoring force. The locking mechanism includes: Through an annular plate, an L-shaped stop, a hinge rod, and a spiral spring; The annular rod used to lock the connecting guide block.

[0005] Furthermore, the outer side of the lifting plate is provided with an annular array of mounting grooves, and the mounting shaft is fixedly installed on the inner wall of the mounting groove. Both ends of the mounting shaft are fixedly connected to a circular plate.

[0006] Furthermore, the bottom of the hook has a through mounting hole, and both sides of the inner wall of the mounting hole are rotatably connected to the outer wall of the circular plate through bearings.

[0007] Furthermore, the inner end of the spiral spring is fixedly connected to the outer wall of the mounting shaft, and the outer end of the spiral spring is fixedly connected to the inner wall of the mounting hole at the bottom of the hook; the spiral spring provides an outward rotational force to the hook, so that the hook remains open outward in a free state.

[0008] Furthermore, multiple guide blocks are provided, arranged in a circular array on the outer side of the lifting plate, and the vertical groove is opened on the side wall of the mounting base, with the inner wall of the vertical groove slidably connected to the outer wall of the guide block.

[0009] Furthermore, a circular plate II is fixedly installed on the outer bottom of the mounting base. The bottom end of the annular plate is rotatably connected to the top end of the circular plate II. An annular protrusion is fixedly installed in the middle of the circular plate II. Multiple mounting shafts II arranged in an annular array are fixedly installed on the top end of the annular protrusion. An upper cover plate is fixedly connected to the top end of the mounting shafts II. The bottom end of the upper cover plate is rotatably connected to the top end of the annular plate, together forming the support frame of the locking mechanism.

[0010] Furthermore, the outer wall of each mounting shaft is connected to an L-shaped stop, and the outer side of each L-shaped stop is rotatably connected to a hinge rod. The other end of the hinge rod is rotatably connected to the inner side of the annular plate, thereby forming a linkage mechanism.

[0011] Furthermore, the second spiral spring is disposed between the lower inner side of the annular plate and the outer side of the annular protrusion, the inner end of the second spiral spring is fixedly connected to the outer wall of the annular protrusion, and the outer end of the second spiral spring is fixedly connected to the inner side of the annular plate.

[0012] Furthermore, the inner wall of the mounting base is designed as an inverted trapezoidal structure, and the outer side of the hook is designed as a matching inverted trapezoidal inclined surface; when the lifting plate is pressed down, the inverted trapezoidal inclined surface contacts and converts the linear motion into a radial driving force that causes the hook to rotate inward.

[0013] A gas detector with a detachable pipeline installation structure, wherein the bottom of the gas detector is provided with a detection port, a limiting groove and an outer edge, and the detection port passes through the through hole of the lifting plate and is sealed with the detection hole.

[0014] The present invention has the following advantages: 1. This detachable pipe installation structure achieves initial alignment of the detection hole and the detection port through the meshing design of the clamp groove and the pipe protrusion, avoiding manual calibration deviation; the connection mechanism adopts a "press-triggered" mechanism: pressing the gas detector with one hand can simultaneously drive the lifting plate to descend, the hook to rotate and retract, and the latch to lock, without the need for tools; when the hook retracts, it forces the detection port to be tightly inserted into the detection hole; when disassembling, simply reverse the handle, and the thrust spring will automatically rise and reset. 2. In this detachable pipe installation structure, the hook mechanism is forcibly guided by the limiting plate during descent. Its inner top precisely hooks onto the upper outer edge of the gas detector, forming a vertical mechanical stop that effectively resists upward jump and disengagement caused by the equipment's own weight and vibration. At the same time, the limiting block on the inner side of the hook is embedded in the limiting groove of the gas detector, forming a circumferential anti-rotation structure to eliminate the risk of horizontal swaying. The locking mechanism drives the L-shaped stop to press against the annular rod through the preload of the spiral spring, so that the lifting plate maintains a constant downward pressure.

[0017] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1; Reference Figures 1-8 A detachable pipeline installation structure includes a pipeline 1, a gas detector 3, and a detachable installation structure installed between the pipeline 1 and the gas detector 3. The pipeline 1 has a detection hole 74 for collecting and detecting data, and a protrusion 73 is installed on the outer side of the top of the detection hole 74. The detachable installation structure includes: Two retaining rings are fitted on both sides of the pipe 1 and fixed together by bolts to form a clamp 2. The upper part of the clamp 2 is connected to the gas detector 3. The top of the inner wall of the clamp 2 has a groove 72, which corresponds to the protrusion 73. The detection port 31 of the gas detector 3 passes through the top of the groove 72 and corresponds to the detection hole 74, so as to introduce the gas in the pipe 1 into the gas detector 3. The inner wall of the detection hole 74 is equipped with a solenoid valve (not shown in the figure). Working principle: Before installation, the solenoid valve in the detection hole 74 is closed. First, the upper retaining ring is installed on the top of the pipe 1, and the groove 72 is inserted into the corresponding protrusion 73, and the detection port 31 is aligned with the detection hole 74. Then, the lower retaining ring is connected to the bottom of the pipe 1, and the upper and lower retaining rings are fixed at both ends with bolts, so that the clamp 2 is fixed to the outer wall of the pipe 1. After installation, the gas detector 3 sends a command or detects the installation in place signal to control the opening of the solenoid valve in the detection hole 74, so that the detection port 31 communicates with the inner wall of the pipe 1, ensuring that gas in the pipe can only enter the detector after correct installation, preventing leakage. Furthermore: A connecting structure is installed between the top of the clamp 2 and the gas detector 3; for detachable connection between the gas detector 3 and the top of the clamp 2; The connecting mechanism includes: a mounting base 41, which is fixedly mounted on the top of the clamp 2; a lifting plate 42 is slidably connected to the inner wall of the mounting base 41; mounting grooves 44 are arranged in annular array on the outer side of the lifting plate 42; a mounting shaft 45 is fixedly mounted on the inner wall of the mounting groove 44; circular plates 46 are fixedly connected to both ends of the mounting shaft 45; a hook 43 is provided on the outer side of the mounting shaft 45; a through mounting hole 48 is provided at the bottom of the hook 43; and both sides of the inner wall of the mounting hole 48 are... The outer wall of the circular plate 46 is rotatably connected to the mounting shaft 45 via a bearing. A spiral spring 47 is installed on the outer wall of the mounting shaft 45. The inner end of the spiral spring 47 is fixedly connected to the outer wall of the mounting shaft 45, and the outer end of the spiral spring 47 is fixedly connected to the inner wall of the mounting hole 48 at the bottom of the hook 43. The spiral spring 47 provides an outward rotational force to the hook 43, so that the hook 43 remains open in a free state. There are multiple hooks 43, which are arranged in a ring array on the outside of the lifting plate 42. Multiple guide blocks 52 are distributed on the outer side of the lifting plate 42. Vertical grooves 51 are arranged in a circular array on the outer side of the mounting base 41. The inner wall of the vertical groove 51 is slidably connected to the outer wall of the guide block 52, restricting the lifting plate 42 to move only along the axial direction of the mounting base 41. A guide rod 53 is fixedly installed on the inner wall of the vertical groove 51. The outer wall of the guide rod 53 is slidably connected to the inside of the guide block 52. A thrust spring (not shown in the figure) is sleeved on the outer wall of the guide rod 53. The bottom end of the thrust spring is fixedly connected to the bottom end of the inner wall of the vertical groove 51. The top end of the thrust spring is connected to the bottom end of the guide block 52. The thrust spring applies an upward thrust to the guide block 52, causing the lifting plate 42 to have an upward tendency. A ring rod 54 is fixedly connected to the outer side of the guide block 52. A circular plate 61 is fixedly installed on the bottom of the outer side of the mounting base 41. A locking mechanism is provided between the circular plate 61 and the ring rod 54. The locking mechanism includes: an annular plate 62, the bottom end of which is rotatably connected to the top end of a circular plate 61; an annular protrusion 64 is fixedly installed in the middle of the circular plate 61; a plurality of mounting shafts 66 arranged in a circular array are fixedly installed on the top end of the annular protrusion 64; a top cover plate 68 is fixedly connected to the top end of the mounting shafts 66; the bottom end of the top cover plate 68 is rotatably connected to the top end of the annular plate 62, together forming the support frame of the locking mechanism; and an L-shaped stop 65 is rotatably connected to the outer wall of each mounting shaft 66. A hinge rod 67 is connected, and the other end of the hinge rod 67 is rotatably connected to the inner side of the annular plate 62, thereby forming a linkage mechanism. A spiral spring 63 is provided between the lower inner side of the annular plate 62 and the outer side of the annular protrusion 64. The inner end of the spiral spring 63 is fixedly connected to the outer wall of the annular protrusion 64, and the outer end of the spiral spring 63 is fixedly connected to the inner side of the annular plate 62. The spiral spring 63 rotates counterclockwise from the inside to the outside, that is, the elastic force of the spiral spring 63 keeps the annular plate 62 rotating clockwise. And the initial state of the L-shaped stop 65 is as follows: Figure 8 As shown, at this time, the vertical part (block) of the L-shaped stop 65 is above the horizontal position, ready to block the upward movement of the annular rod 54; a handle 69 is fixedly connected to the outer side of the annular plate 62. Pulling the handle 69 causes the annular plate 62 to rotate clockwise, and the annular plate 62 causes the L-shaped stop 65 to rotate counterclockwise around the second mounting shaft 66 through the hinge rod 67, so that the vertical part of the L-shaped stop 65 is raised to a near-vertical state, thereby releasing the restriction on the annular rod 54; at this time, the second spiral spring 63 provides the force for the clockwise rotation of the annular plate 62; after releasing the handle 69, under the influence of the reset pull of the second spiral spring 63, the annular plate 62 automatically rotates counterclockwise to reset, and drives the L-shaped stop 65 to rotate clockwise back to the initial blocking position through the hinge rod 67; Through holes 71 are provided on the lifting plate 42 and the mounting base 41. A limiting groove 32 is provided on the lower outer side of the gas detector 3, and an outer edge 33 is provided on the upper outer side of the limiting groove 32. During use; the initial state of the lifting plate 42 and the hook 43 is as follows: Figure 5 As shown, the lifting plate 42 is in the highest position under the action of the thrust spring, and the hook 43 opens outward under the action of the spiral spring 47. When installing the gas detector 3, the bottom of the gas detector 3 contacts the top of the lifting plate 42, and at the same time, the detection port 31 at the bottom of the gas detector 3 is inserted into the through hole 71. Pulling handle 69 causes the annular plate 62 to rotate clockwise, and the annular plate 62, through hinge rod 67, causes the L-shaped stop 65 to rotate counterclockwise around mounting shaft 66; thus releasing the restriction on the annular rod 54. The gas detector 3 pushes the lifting plate 42 down, and the lifting plate 42 drives the annular rod 54 to move down through the guide block 52 while squeezing the thrust spring; the annular rod 54 is moved down to below the L-shaped stop 65; the handle 69 is released, and the annular plate 62 is rotated clockwise by the reset pull of the spiral spring 63. The annular plate 62 pushes the L-shaped stop 65 to rotate counterclockwise through the hinge rod 67, and it abuts against the top of the annular rod 54 to form a lock, restricting the upward movement of the annular rod 54 and the lifting plate 42; When the lifting plate 42 descends, the upper part of the hook 43 (especially its inner inclined or curved surface) will contact and be squeezed against the limiting plate 49 on the inner side of the mounting base 41. Affected by the mounting base 41, the hook 43 is forced to overcome the force of the spiral spring 47 and rotate inward to clamp the gas detector 3. The inner top of the hook 43 is stuck above the outer edge 33 of the gas detector 3. The gas detector 3 is restricted from moving vertically (moving upwards). At the same time, when clamped, the limiting block 431 inside the hook 43 is engaged into the limiting groove 32, restricting the gas detector 3 from moving horizontally (rotating or shaking). The mounting base 41 has a ring array of limiting plates 49 distributed on the upper inner side. Example 2: Basically the same as in Example 1, but further: referring to Figures 1-8 A detachable pipe installation structure, wherein the inner wall of the mounting base 41 is set in an inverted trapezoid; the outer side of the hook 43 is set in an inverted trapezoid; the two fit together. Working principle: The inverted trapezoidal inner wall of the mounting base 41 and the inverted trapezoidal inclined surface of the hook 43 fit together. When the lifting plate 42 is subjected to downward pressure and drives the hook 43 to descend, the inverted trapezoidal inclined surface of the hook 43 will slide along the inverted trapezoidal inclined surface of the inner wall of the mounting base 41. This inclined surface contact effectively converts the downward linear movement of the lifting plate 42 into a driving force that forces the hook 43 to overcome the elastic force of the spiral spring 47 and rotate and retract inward stably and smoothly. This inverted trapezoidal design significantly optimizes the guiding properties of the hook 43, ensuring that multiple hooks 43 can complete the clamping action of the gas detector 3 more synchronously and reliably, while enhancing the stability of the clamping mechanism in a vibration environment.
