Description

Technical Field

[0001] This invention relates to the field of temperature element mounting structure technology, specifically to a shock-resistant supporting component for temperature elements. Background Technology

[0002] In industrial applications such as the outlet pipeline of the heat network heater desuperheater and pressure reducer, temperature measuring elements are usually used to continuously monitor the temperature of the medium. In the existing technology, the temperature measuring elements are mostly directly installed on the pipeline through a temperature base and fixed by a movable clamp.

[0003] However, in actual operation, some pipelines exhibit excessive vibration amplitude, causing temperature sensing elements to endure high-frequency, large-amplitude vibration loads for extended periods. This leads to fatigue damage at the element root and connection points, resulting in frequent breakage or signal transmission interruptions. During the winter heating season, such failures directly prevent continuous and accurate monitoring of the heating network medium temperature after de-cooling and depressurization. This affects the timely adjustment of heating network system operating parameters, reducing heating quality and operational stability. Furthermore, frequent element replacement and maintenance significantly increase the workload of maintenance personnel and the cost of spare parts, posing a potential threat to heating supply security. Therefore, we propose a vibration-resistant component for temperature sensing elements. Summary of the Invention

[0011] Preferably, the straight groove is divided into three groups of regions along the axial direction of the first sleeve. Each group of regions contains multiple straight grooves arranged in a circular array. The straight groove at the center is staggered from the straight grooves on both sides. The number of rotating rings is set in two groups, and the two groups of rotating rings are set at the center between two adjacent groups of straight grooves.

[0012] Preferably, the sliding block is arranged in a cross shape, and the straight groove has a cross-shaped groove inside that is adapted to the size of the sliding block.

[0013] Preferably, the third sleeve is provided with a tail end protection assembly at the end away from the second sleeve to provide vibration protection for the wires coupled to the temperature element.

[0016] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0017] 1. This invention, by setting up a reinforced connection component, adopts a conical surface mating structure of a conical ring and an inner conical groove at the connection end between the sleeves. With the fitting and positioning of the convex ring and the mating ring groove, a radial self-locking force is generated during the thread tightening process, which enhances the anti-loosening ability of the connection part. At the same time, the extrusion component set in the side annular groove uses a spring to push the triangular block, converting the axial thrust into a radial extrusion force on the side sealing ring, so that the side sealing ring always maintains a tight fit with the contact surface, compensating for the gap caused by vibration or aging of the seal, reducing the loosening and sealing failure of the connection part under long-term vibration environment, and solving the problem of fatigue damage and frequent breakage of the root and connection parts of the temperature sensing element caused by pipeline vibration.

[0018] 2. This invention also incorporates an internal support assembly. Straight grooves are formed on the inner arc surfaces of the first, second, and third sleeves. The sliding block slides along the straight grooves and forms rolling contact with the outer wall of the temperature element through contact ball one. This allows the temperature element to freely expand and contract axially during thermal expansion and contraction, resulting in staggered distribution of support points in the axial direction. This avoids excessive concentration of support positions, preventing stress concentration areas. Simultaneously, multiple sets of contact balls two on the inner arc surface of the rotating ring form multi-point rolling support with the outer wall of the temperature element. The rotating ring can adaptively rotate with the slight deflection of the temperature element, filling the support gaps between the straight grooves. This achieves continuous support for the temperature element throughout its entire length, preventing the temperature element from colliding with the inner wall of the sleeve under vibration conditions. This solves the problem of surface wear or fatigue damage caused by long-term vibration and collision with the inner wall of the sleeve.

[0019] 3. This invention also incorporates a tail-end protection component and a flexible support component. An axially floating inner ring is installed at the end of the third sleeve. A spring absorbs axial vibration energy between the sliding rod and the outer sleeve, allowing the inner ring to adaptively float with vibration. The connecting ring forms a rotational fit with the inner ring through a T-shaped ring structure. A coil spring provides torsional buffering, allowing the outer ring to adaptively rotate with the direction of conductor torsion. In the flexible support component installed on the inner arc surfaces of the inner and outer rings, a spring pushes the connecting arm to keep the contact wheel pressed against the outer wall of the conductor. The contact wheel and the conductor form a rolling contact, providing stable support while allowing the conductor to freely extend and retract axially. This provides multi-dimensional flexible protection for the conductor connected to the tail end of the temperature element in the axial, radial, and torsional directions, solving the problem of signal transmission interruption caused by bending or torsional stress in the conductor at the tail end of the temperature element under vibration conditions.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] See attached document Figure 1-8 The present invention provides a shock-resistant supporting component for a temperature element, including a first sleeve 1, a second sleeve 2 threadedly connected to the end of the first sleeve 1, and a third sleeve 3 threadedly connected to the end of the second sleeve 2 away from the first sleeve 1. A reinforced connection component 4 is provided between the end of the first sleeve 1, the first sleeve 1 and the second sleeve 2, and the second sleeve 2 and the third sleeve 3 to adapt to a stable connection in a high-vibration environment. The reinforced connection component 4 includes a connecting cover 41, an inner conical groove 44, a convex ring 42, a conical ring 43, a mating ring groove 45, an upper annular groove 46, a side annular groove 47, an upper sealing ring 48, and a side sealing ring 49.

[0031] The connecting cover 41 is fixedly installed on the end of the first sleeve 1 near the second sleeve 2. The side wall of the connecting cover 41 is provided with an inner conical groove 44. A convex ring 42 is fixedly installed at the center of the inner conical groove 44. A conical ring 43 is fixedly installed on the outer wall of the end of the second sleeve 2 near the first sleeve 1. A mating ring groove 45 is provided on the outer wall of the side of the conical ring 43 near the first sleeve 1. An upper annular groove 46 is provided on the outer arc surface at the center of the conical ring 43. A side annular groove 47 is provided on the outer wall of the end of the conical ring 43 near the first sleeve 1. An upper sealing ring 48 is fitted inside the upper annular groove 46, and a side sealing ring 49 is fitted inside the side annular groove 47.

[0032] The first sleeve 1 is directly connected to the temperature base for installing the temperature element, providing the installation foundation for the overall structure. The second sleeve 2 is connected to the first sleeve 1 by threads to form a detachable fixed structure. The third sleeve 3 is also connected to the second sleeve 2 by threads to form an integral three-section sleeve body. The reinforcing connection component 4 is set at the connection end between the first sleeve 1 and the second sleeve 2 and the connection end between the second sleeve 2 and the third sleeve 3, to enhance the connection stability between the sleeves in a high vibration environment. In addition, the inner conical groove 44 opened inside the connecting cover 41 forms a conical surface fit with the conical ring 43, which enhances the radial fastening force of the connection through the conical surface self-locking effect. The fitting structure of the convex ring 42 and the mating ring groove 45 provides axial positioning and anti-loosening function. The upper sealing ring 48 is installed in the upper annular groove 46, and the side sealing ring 49 is installed in the side annular groove 47. The two are used to seal the connection part, prevent external impurities from entering and buffer vibration energy.

[0033] It is worth noting that the temperature base used for docking with the temperature element is provided with another set of connecting covers 41 that can dock with the conical ring 43 and docking ring groove 45 provided at the end of the first sleeve 1. The inner side of the cover is also provided with an inner conical groove 44 and a convex ring 42, so that the end of the first sleeve 1 can also be strengthened to improve the vibration resistance.

[0034] The tapered ring 43 is provided with a tapered surface on the side near the first sleeve 1, and the shape of the tapered surface is adapted to the size of the inner tapered groove 44. At the same time, the convex ring 42 is adapted to the size of the mating ring groove 45.

[0035] The tapered surface of the tapered ring 43 near the first sleeve 1 forms a tight tapered surface fit with the inner tapered surface of the inner tapered groove 44. During the thread tightening process, the two generate a radial component force, which enables the connection structure to maintain a self-locking state under high-frequency vibration. The size of the convex ring 42 is matched with the mating ring groove 45, so that the convex ring 42 can be completely embedded in the mating ring groove 45, forming an axial positioning and anti-disengagement structure, which restricts the relative axial displacement between the first sleeve 1 and the second sleeve 2.

[0036] Please see Figure 5 The interior of the side annular groove 47 is arranged in a circumferential array with several extrusion components 5 that support the tight connection of the side sealing ring 49. The extrusion component 5 includes an arc-shaped plate 51 fixedly installed on the inner wall of the end of the side annular groove 47. A small sleeve 52 is fixedly installed on the side wall of the arc-shaped plate 51. A short rod 53 is slidably installed on the inner wall of the small sleeve 52. A triangular block 54 is fixedly installed on one end of the short rod 53 near the side sealing ring 49. A spring 55 is fixedly connected between the other end of the short rod 53 and the inner wall of the small sleeve 52.

[0037] The short rod 53 slides inside the small sleeve 52, and the triangular block 54 connected to one end continuously presses against the side sealing ring 49 under the elastic force of the spring 55, so that the side sealing ring 49 always maintains a tight fit with the contact surface, thereby compensating for the sealing gap caused by vibration or aging.

[0038] The bottom surface of the triangular block 54 is configured as an arc shape that fits against the inner bottom surface of the side annular groove 47, and the inclined surface of the triangular block 54 is configured on the side facing the side sealing ring 49.

[0039] Triangular block 54 can maintain a stable movement trajectory during sliding, avoiding deflection or jamming. The side of triangular block 54 facing the side sealing ring 49 is set as an inclined surface. This inclined surface converts the axial thrust of spring 55 into the radial extrusion force on the side sealing ring 49, realizing efficient transmission and uniform distribution of sealing pressure.

[0040] Please see Figure 6 The inner arc surfaces of the first sleeve 1, the second sleeve 2, and the third sleeve 3 are provided with internal support components 6 for mid-section support of the inserted temperature element. The internal support components 6 include a straight groove 61 opened on the inner arc surface of the first sleeve 1, a sliding block 62 slidably installed on the inner surface of the straight groove 61, a contact ball 63 movably installed on the inner wall of the sliding block 62 near the center of the first sleeve 1, and a rotating ring 64 rotatably installed on the inner arc surface of the first sleeve 1. Multiple sets of contact balls 65 are arranged in a circular array on the inner arc surface of the rotating ring 64.

[0041] The internal support assembly 6 prevents the temperature element from colliding with the inner wall of the sleeve under vibration. The straight groove 61 is opened on the inner arc surface of the first sleeve 1 to guide the sliding block 62 to slide axially. The sliding block 62 slides in the straight groove 61. The contact ball 63 installed inside it forms a rolling contact with the outer wall of the temperature element, which provides support and allows the temperature element to freely expand and contract axially. The rotating ring 64 is rotatably installed on the inner arc surface of the first sleeve 1. Multiple sets of contact balls 65 arranged in a circular array on its inner arc surface form multi-point rolling support with the outer wall of the temperature element. At the same time, the rotating ring 64 can adaptively rotate with the slight deflection of the temperature element to avoid generating additional stress.

[0042] The straight groove 61 is divided into three groups of regions along the axis of the first sleeve 1. Each group of regions contains multiple straight grooves 61 arranged in a circular array. The straight groove 61 in the center is staggered from the straight grooves 61 on both sides. There are two sets of rotating rings 64, which are located at the center between two adjacent groups of straight grooves 61.

[0043] The three sets of straight grooves 61, along with the corresponding sliding blocks 62 and contact balls 63 inside them, can achieve multi-section support for the temperature element. The set of straight grooves 61 at the center is staggered with the straight grooves 61 on both sides, so that the support points are staggered in the axial direction, avoiding the formation of stress concentration areas due to excessive concentration of support positions. The two sets of rotating rings 64 are respectively set at the center between the two adjacent sets of straight grooves 61, and are used to fill the support gaps between the straight grooves 61, so as to achieve continuous support for the temperature element throughout its entire length.

[0044] The sliding block 62 is arranged in a "+" shape, and the straight groove 61 has a "+" shaped groove inside that is adapted to the size of the sliding block 62.

[0045] The cross-section design restricts the rotational freedom of the sliding block 62 in the radial direction, ensuring that the sliding block 62 slides only in a straight line along the axial direction. At the same time, it increases the contact area between the sliding block 62 and the straight groove 61, improves the ability of the sliding block 62 to withstand radial loads, and avoids skewing or dislodging under vibration conditions.

[0046] Please see Figure 7 The third sleeve 3 is provided with a tail end protection assembly 7 at the end away from the second sleeve 2 to provide vibration protection for the wires coupled to the temperature element. The tail end protection assembly 7 includes multiple outer sleeves 71 fixedly installed in a circumferential array on the outer wall of the end of the third sleeve 3. A slide rod 72 is slidably installed on the inner wall of the outer sleeve 71. A spring 73 is fixedly connected between the end of the slide rod 72 and the inner wall of the outer sleeve 71. An inner ring 74 is fixedly connected to the other end of the slide rod 72. A connecting ring 75 is rotatably installed on the inner wall of the inner ring 74 away from the slide rod 72. A coil spring 76 is fixedly connected between the inner arc surface of the connecting ring 75 and the inner wall of the inner ring 74. An outer ring 77 is fixedly connected to the side wall of the connecting ring 75. Multiple flexible support assemblies 8 are arranged in a circumferential array on the inner arc surfaces of both the inner ring 74 and the outer ring 77.

[0047] The outer sleeve 71 is fixed in a circumferential array to the outer wall of the end of the third sleeve 3, serving as the mounting base for the tail end protection component 7. The slide rod 72 slides in the inner wall of the outer sleeve 71. The second spring 73 is connected between the end of the slide rod 72 and the inner wall of the outer sleeve 71, providing axial buffering. The inner ring 74 is fixed to the other end of the slide rod 72 and can float axially with vibration. The connecting ring 75 is rotatably installed on the inner wall of the inner ring 74. The coil spring 76 is connected between the inner arc surface of the connecting ring 75 and the inner wall of the inner ring 74, providing torsional buffering. The outer ring 77 is fixed to the side wall of the connecting ring 75 and together with the inner ring 74, forms a wire clamping structure that can adaptively adjust with vibration. The flexible support component 8 is set on the inner arc surface of the inner ring 74 and the outer ring 77 to provide flexible support for the wire and prevent the wire from bending and being damaged under vibration.

[0048] Among them, spring 1 55, spring 2 73 and spring 3 84 are all made of heat-resistant alloy steel (such as silicon-chromium steel, chromium-vanadium steel, etc.) to ensure that they can maintain elastic force within a certain temperature range, thereby realizing the elastic function.

[0049] The surface of the connecting ring 75 near the inner ring 74 is configured as a T-shaped ring, and the inner wall of the inner ring 74 away from the outer sleeve 71 is provided with a T-shaped ring groove that matches the end of the connecting ring 75.

[0050] The T-shaped ring structure and the T-shaped ring groove form an axially limiting rotational fit, allowing the connecting ring 75 to rotate freely inside the inner ring 74 without axially dislodging. This ensures that the connecting ring 75 can rotate with the conductor when subjected to torsional torque, preventing damage to the conductor due to torsional stress.

[0051] Please see Figure 8 The flexible support component 8 includes a fixed cylinder 81 fixedly installed on the inner arc surface of the inner ring 74. A connecting arm 82 is slidably installed on the inner wall of the fixed cylinder 81. A contact wheel 83 is rotatably installed on the inner wall of the connecting arm 82 near the center of the inner ring 74. A spring 84 is fixedly connected between the end of the connecting arm 82 away from the contact wheel 83 and the inner wall of the fixed cylinder 81.

[0052] The connecting arm 82 slides within the inner wall of the fixed cylinder 81. A contact wheel 83, rotatably mounted at one end, rolls against the outer wall of the conductor. A spring 84 is connected between the end of the connecting arm 82 away from the contact wheel 83 and the inner wall of the fixed cylinder 81, providing the connecting arm 82 with an elastic thrust toward the conductor. This ensures that the contact wheel 83 is always pressed against the outer wall of the conductor, providing stable support while allowing the conductor to freely extend and retract axially and adapting to minor bends in the conductor, thus achieving flexible protection in a vibration environment.

[0053] Working principle: First, the first sleeve 1 is connected to the temperature base on the pipeline. The conical ring 43 at the end of the first sleeve 1 forms a conical surface fit with the conical groove 44 in the corresponding connecting cover 41 on the temperature base. At the same time, the convex ring 42 is embedded in the docking ring groove 45. The conical surface generates a radial self-locking force by tightening the thread, thus completing the fixed installation of the first sleeve 1. Then, the second sleeve 2 is threaded to the first sleeve 1. The conical ring 43 at the end of the second sleeve 2 forms a conical surface fit with the conical groove 44 in the connecting cover 41 at the end of the first sleeve 1. The convex ring 42 is embedded in the docking ring groove 45 to achieve axial positioning. At the same time, the upper sealing ring 48 is sleeved in the upper annular groove 46, and the side sealing ring 49 is sleeved in the side annular groove 47, forming a double sealing structure. The third sleeve 3 is threaded to the second sleeve 2 in the same way, thus completing the assembly of the three-section sleeve body.

[0054] During the tightening of each sleeve thread, the spring 55 in the side annular groove 47 pushes the short rod 53 to slide along the inner wall of the small sleeve 52. The short rod 53 drives the triangular block 54 to move towards the side sealing ring 49. The inclined surface of the triangular block 54 converts the axial thrust of the spring 55 into a radial extrusion force on the side sealing ring 49, so that the side sealing ring 49 always maintains a tight fit with the contact surface, compensating for the gap caused by the difference in thread tightening or the aging of the seal after long-term use.

[0055] When the temperature element is inserted into the three-section sleeve, the sliding block 62 slides axially along the straight groove 61. The contact ball 63 on the inner side of the sliding block 62 forms a rolling contact with the outer wall of the temperature element, allowing the temperature element to freely expand and contract axially during thermal expansion and contraction. The set of straight grooves 61 at the center is staggered with the straight grooves 61 on both sides, so that the support points of the contact ball 63 are staggered in the axial direction. The rotating ring 64 is rotatably installed on the inner arc surface of the sleeve. The multiple sets of contact balls 65 arranged in a circular array on its inner side form a multi-point rolling support with the outer wall of the temperature element. The rotating ring 64 can adaptively rotate with the slight deflection of the temperature element, fill the support gap between the straight grooves 61, realize the continuous support of the temperature element in the entire length range, and prevent the temperature element from colliding with the inner wall of the sleeve in a vibration environment.

[0056] After the wire connected to the tail end of the temperature element passes through the third sleeve 3, the wire passes through the inner ring 74, the connecting ring 75 and the outer ring 77 in sequence. The spring 84 in the flexible support assembly 8 pushes the connecting arm 82 to slide along the inner wall of the fixed cylinder 81. The contact wheel 83 at the end of the connecting arm 82 is always pressed against the outer wall of the wire under the elastic thrust of the spring 84. The contact wheel 83 forms a rolling contact with the wire, allowing the wire to freely expand and contract along the axial direction. When the pipe vibration is transmitted to the tail end, the slide rod 72 slides along the inner wall of the outer sleeve 71. The spring 73 absorbs the axial vibration energy, allowing the inner ring 74 to float along the axial direction. When the wire is subjected to torsional torque, the connecting ring 75 forms a rotational engagement with the T-shaped groove of the inner ring 74 through the T-shaped ring structure. The coil spring 76 provides torsional buffering, allowing the outer ring 77 to rotate adaptively with the torsional direction of the wire, avoiding damage to the wire due to torsional stress.
