Abstract
Description
Technical Field
[0001] This utility model relates to the field of composite sleeve technology, and more specifically, to a composite sleeve device for thermal pipelines. Background Technology
[0002] In heat transfer systems, heat pipelines, as core components, play a crucial role in the efficient and stable transmission of heat energy. To ensure the safe operation of pipelines in complex environments (such as underground laying or crossing buildings), casing devices are typically installed to protect and position the pipelines. Traditional casing devices often employ a single material or a simple structural design, which, while providing some protection, are significantly inadequate in addressing the unique thermal expansion and contraction phenomena of heat pipelines.
[0003] Because thermal pipelines undergo significant deformation due to thermal expansion and contraction, their length and diameter change. When the pipeline passes through the limiting element within the casing, the gap between the limiting element and the pipeline is difficult to precisely match. If the gap is too small, it will restrict pipeline deformation, leading to stress concentration, accelerating pipeline aging, and even causing rupture. If the gap is too large, the pipeline will lack effective restraint within the casing, making it prone to swaying during operation. This not only generates additional noise but may also cause the pipeline to collide and rub against the casing and surrounding structures, further threatening the safe operation of the thermal pipeline and increasing maintenance costs and risks.
[0004] Therefore, we have made improvements to this and proposed a composite sleeve device specifically for thermal pipelines. Utility Model Content

[0011] The second spring is rotatably disposed on the inner ring of the sleeve body and is located between the first springs and offset from the first springs; the spacer is disposed on both sides of the second spring and passes through the spacer between two adjacent first springs;
[0012] Mounting plates are circumferentially distributed on the circular surface of the sleeve body;

[0015] When the limiting column is installed with different mounting plates, the limiting column drives the first elastic sheet and indirectly drives the second elastic sheet, so that the first elastic sheet and the second elastic sheet are in elastic contact with the heat pipe body.
[0016] Preferably, the fixed ring is provided with a fixed plate matched with the mounting plate, and the fixed ring covers at least one third of the gap between the first elastic sheets.

[0030] In order to enable personnel in the technical field to better understand the present application scheme, the technical scheme in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts shall belong to the scope of protection of the present application.
[0031] Embodiments, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , a special composite sleeve device for heat pipes, comprising:
[0032] a heat pipe body 1;
[0033] a sleeve body 2, which is a semicircular pipe symmetrically sleeved on the outer ring of the heat pipe body 1, has:
[0034] a first elastic sheet 21, which is uniformly distributed on the inner ring of the sleeve body 2 and located at the first and last sides of the sleeve body 2, and rotates along the joint of the sleeve body 2 as a rotation point, and is in contact with the heat pipe body 1;
[0035] a second elastic sheet 23, which is rotatably arranged on the inner ring of the sleeve body 2 and located between the first elastic sheets 21 and the first elastic sheets
[0036] 21 are misaligned;
[0037] a spacer column 24, which is arranged on both sides of the second elastic sheet 23 and passes through between the adjacent two first elastic sheets 21;
[0038] The mounting plate 25 is circumferentially distributed on the circular surface of the sleeve body 2;
[0039] The fixing ring 5 is an open ring rotating on one side, fixedly connected with the mounting plate 25, coaxially arranged with the sleeve body 2, and provided with:
[0040] The limiting column 51 is uniformly distributed on the fixing ring 5 and penetrates between two adjacent first elastic sheets 21;
[0041] When the limiting column 51 is installed with different mounting plates 25, the limiting column 51 drives the first elastic sheet 21 and indirectly drives the second elastic sheet 23, so that they are in elastic contact with the heat pipe body 1;
[0042] When the heat pipe body 1 exchanges heat and causes the surface to deform, it is difficult for the sleeve body 2 to limit the heat pipe body 1, so in this scheme, two sleeve bodies 2 are sleeved on the heat pipe body 1, and the first elastic sheet 21 and the second elastic sheet 23 are in tangential contact with the heat pipe body 1, so that the first elastic sheet 21 and the second elastic sheet 23 are in elastic contact with the heat pipe body 1;
[0043] At the same time, when the fixing ring 5 is installed on both sides of the heat pipe body 1, the fixing plate 52 on the fixing ring 5 is installed on the mounting plate 25 at different positions through the connecting member such as a bolt, so that the limiting column 51 drives the first elastic sheet 21 to form different vertical positions, and can adapt to heat pipe bodies 1 of different sizes, and the connecting ring 22 adjusts the first elastic sheet 21 and the second elastic sheet 23 as a whole;
[0044] Then, under the limitation of the spacing column 24, the second elastic sheet 23 is always arranged in a staggered manner with the first elastic sheet 21, so that the space inside the sleeve body 2 is divided into multiple staggered cavities, causing heat to accumulate, and because the fixing ring 5 limits the air vents on both sides, when the elastic sheet contacts the heat pipe body 1, the heat is conducted out by the elastic sheet, and the heat transfer rate of the heat pipe body 1 is increased, but the heat is orderly dissipated under the above multiple limiting conditions, so that the heat does not dissipate instantaneously and surrounds the pipe, so that the pipe does not undergo sharp heat exchange, reducing the possibility of deformation, and even if deformation occurs, because the connecting ring 22 is an elastic structure, each elastic sheet can independently adjust the deformation position corresponding to it, so that the sleeve body 2 has a better limiting effect on the heat pipe body 1.
[0045] The fixing ring 5 is provided with a fixing plate 52 cooperating with the mounting plate 25, and the fixing ring 5 covers at least one third of the gap between the first elastic sheets 21, so that the heat exchange effect with the atmosphere is reduced.
[0046] The interval column 24 is located at the narrowest angle between two adjacent first elastic sheets 21, so that when the first elastic sheet 21 rotates, the rotating force is transmitted to the second elastic sheet 23 through the interval column 24, and through the multi-layer channel, the elastic sheet can quickly export the heat of the heat pipe body 1, but the discharge efficiency is reduced.
[0047] The second elastic sheet 23 is provided with a wave-shaped protrusion, and the lowest point of the wave-shaped protrusion is kept at a predetermined distance from the surface of the heat pipe body 1 to form an air flow channel, so that the heat transfer rate in the middle is the largest, and the heat cannot be quickly dissipated due to the large heat in the middle.
[0048] The first elastic sheet 21 and the second elastic sheet 23 are respectively provided with a connecting ring 22 connected to each other, and the connecting ring 22 is connected to the first elastic sheet 21 and the second elastic sheet 23 on the single sleeve body 2.
[0049] The technical scope of the utility model is not limited to the content in the above description, and those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical thought of the utility model, and these deformations and modifications should all belong to the protection scope of the utility model.
