Description

Technical Field

[0001] The utility model relates to the technical field of heating pipes, in particular to a heating pipe with a heat preservation structure. Background Technique

[0002] A heating pipe network refers to a pipeline system that transports and distributes heating media from a centralized heating source in a city to heat users. The heating medium flows through the heating pipes. The heating pipes are generally divided into underground laying and above-ground laying. The underground laid pipes are directly buried in the soil without a trench. The pipes themselves directly bear external loads, with low cost and simple construction. The above-ground laid pipes are also called overhead laying, and the pipes are installed on brackets. Since the overhead laid pipes are installed outdoors and are affected by external factors such as weather and temperature, more heat loss may occur. Therefore, it is necessary to install a heat preservation structure on the pipes with reduced heating efficiency in a timely manner. Most of the existing heat preservation structures are directly sleeved on the outer circle of the pipes.

[0003] The patent with the publication number of CN220453102U discloses a heat preservation structure for a heating pipe network, including a heating pipe, a first heat preservation layer, a second heat preservation layer and a fastening strap. The first heat preservation layer and the second heat preservation layer are respectively located on both sides of the outer circle of the heating pipe. At the top position of the inner circle of the first heat preservation layer, a first inner lining layer is provided. At the top position of the inner circle of the second heat preservation layer, an upper pressing groove is provided corresponding to the first inner lining layer. At the bottom position of the inner circle of the second heat preservation layer, a second inner lining layer is provided. At the bottom position of the inner circle of the first heat preservation layer, a lower pressing groove is provided corresponding to the second inner lining layer. By setting the first heat preservation layer and the second heat preservation layer outside the heating pipe and respectively setting the first inner lining layer and the second inner lining layer, the heat preservation structure can be directly installed outside the pipe without disassembling the heating pipe, improving the installation efficiency of the heat preservation structure. At the same time, by using the inner lining layer in cooperation with the fastening strap, the sealing performance and stability can be effectively enhanced, and the heat preservation effect can be improved.

[0004] The installation of the above-mentioned existing heat preservation structure usually depends on a plurality of fastening straps, that is, a plurality of fastening straps need to be carried when installing the heat preservation structure, which has certain inconvenience. This not only increases the installation complexity but also limits the ability of quick disassembly and assembly. In view of this, we propose a heating pipe with a heat preservation structure. Content of the Utility Model

[0005] The purpose of the utility model is to provide a heating pipe with a heat preservation structure to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A heat supply pipe with a heat preservation structure includes a heat supply pipe body, which serves as the main channel for heat medium transmission, responsible for transporting and distributing the heat supply medium, and a first semi-circular heat preservation cover and a second semi-circular heat preservation cover wrapped outside the heat supply pipe body, providing an overall heat preservation effect and reducing heat loss. At the front and rear edges of the convex surface of the first semi-circular heat preservation cover, first docking parts are provided. The first docking part includes a first strip-shaped plate fixedly connected to the outside of the first semi-circular heat preservation cover, serving as the basic support structure of the first docking part. Circular holes a are opened at the bottom of the first strip-shaped plate and near the left and right ends for the threaded connecting rod to pass through. At the top of the first strip-shaped plate and at the positions of the two circular holes a, internal thread fixing blocks are provided to provide threaded connection for fixing the threaded connecting rod and maintaining the stable connection of the cover body.

[0008] At the front and rear edges of the convex surface of the second semi-circular heat preservation cover, second docking parts are provided. The first docking part and the second docking part cooperate to connect the first semi-circular heat preservation cover and the second semi-circular heat preservation cover, ensuring their stable fixation when covering the heat supply pipe body. The second docking part includes a second strip-shaped plate fixedly connected to the outside of the second semi-circular heat preservation cover. Circular holes b are opened at the bottom of the second strip-shaped plate and near the left and right ends. Circular shells are provided at the bottom of the second strip-shaped plate and at the positions of the two circular holes b to wrap the threaded connecting rod and provide guidance and support for it. A threaded connecting rod is movably connected inside the circular shell. The threaded end of the threaded connecting rod sequentially passes through the circular hole b and the circular hole a and is threadedly connected to the internal thread fixing block to connect and fasten the first semi-circular heat preservation cover and the second semi-circular heat preservation cover to ensure their firmness. An annular anti-detachment block is provided on the outer wall of the threaded connecting rod, and the top of the annular anti-detachment block abuts against the bottom of the second strip-shaped plate to prevent the second strip-shaped plate from moving downward after connection and provide a fixation guarantee.

[0009] Preferably, the first semi-circular heat preservation cover includes a first heat preservation layer, a heat insulation and reflection layer, a second heat preservation layer, a moisture-proof isolation layer and an outer protection layer arranged in sequence from inside to outside. The second semi-circular heat preservation cover has the same structure as the first semi-circular heat preservation cover. The first heat preservation layer is made of mineral wool to form a complete heat preservation layer. The heat insulation and reflection layer is located outside the first heat preservation layer and is tightly wrapped with aluminum foil coils. The second heat preservation layer uses aerogel material and is covered on the heat insulation and reflection layer by bonding or spraying. The moisture-proof isolation layer uses high-density polyethylene film and is tightly wrapped outside the second heat preservation layer. The outer protection layer uses cross-linked polyethylene material to provide overall structural protection. The first heat preservation layer, the heat insulation and reflection layer, the second heat preservation layer, the moisture-proof isolation layer and the outer protection layer respectively form the multi-layer structure of the heat preservation cover, providing heat preservation, heat insulation, moisture-proof and protection functions from inside to outside, ensuring the efficient heat transfer of the heat supply pipe body and the adaptability to the external environment.

[0010] Preferably, the bottom end of the threaded connecting rod passes through the bottom of the inner wall of the circular housing to the outside, and a knob is provided at the bottom end of the threaded connecting rod for manually adjusting and fastening the threaded connecting rod, facilitating quick disassembly and assembly.

[0011] Preferably, when the bottom of the annular anti-detachment block fits against the bottom of the inner wall of the circular housing, the threaded end of the threaded connecting rod is located within circular hole b, preventing interference with the initial docking of the first strip plate and the second strip plate.

[0012] Preferably, two positioning holes arranged symmetrically left and right are provided at the bottom of the first strip plate, and two positioning blocks arranged symmetrically left and right are provided at the top of the second strip plate. The two positioning blocks are respectively inserted into the two positioning holes to ensure the precise docking and initial position fixation between the first strip plate and the second strip plate.

[0013] Preferably, two L-shaped moving plates that can be adjusted back and forth are provided at the top of the first strip plate. A support convex block is provided at the bottom inside the L-shaped moving plate, and the top of the support convex block abuts against the bottom of the second strip plate to provide additional support and positioning. After the initial docking of the first strip plate and the second strip plate, the L-shaped moving plate and the support convex block can be used to initially fix the positions of the first strip plate and the second strip plate, preventing the separation of the first semi-circular heat preservation cover and the second semi-circular heat preservation cover.

[0014] Preferably, two waist-shaped holes arranged symmetrically left and right are provided at the top of the L-shaped moving plate. A fixing bolt is connected within the waist-shaped holes, and a threaded groove for threaded connection of the fixing bolt is provided at the top of the first strip plate. The fixing bolt limits the position of the L-shaped moving plate, enabling the L-shaped moving plate to move back and forth. During installation, first move the L-shaped moving plate away from the first semi-circular heat preservation cover to prevent the support convex block from obstructing the movement of the second strip plate towards the first strip plate.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. For the heat supply pipe with a heat preservation structure, compared with the traditional design that requires multiple fastening straps, this structure realizes quick installation and disassembly through the design of the threaded connecting rod and the internal thread fixing block, reduces the installation complexity, improves the work efficiency, and does not require carrying additional fixing structures.

At the front and rear edges of the convex surface of the first semi-circular heat preservation cover 2, first docking members 4 are provided. The first docking member 4 includes a first strip plate 40 fixedly connected to the outside of the first semi-circular heat preservation cover 2, serving as the basic support structure of the first docking member 4. Circular holes a400 are opened at the bottom of the first strip plate 40 and near the left and right ends for the threaded connecting rod 52 to pass through. Inner threaded fixing blocks 41 are provided at the top of the first strip plate 40 and at the positions of the two circular holes a400, providing threaded connection for fixing the threaded connecting rod 52 and maintaining the stable connection of the cover body;

[0030] At the front and rear edges of the convex surface of the second semi-circular heat preservation cover 3, second docking members 5 are provided. The first docking member 4 and the second docking member 5 cooperate to connect the first semi-circular heat preservation cover 2 and the second semi-circular heat preservation cover 3 to ensure their stable fixation when covering the heat supply pipe body 1. The second docking member 5 includes a second strip plate 50 fixedly connected to the outside of the second semi-circular heat preservation cover 3. Circular holes b500 are opened at the bottom of the second strip plate 50 and near the left and right ends. Circular shells 51 are provided at the bottom of the second strip plate 50 and at the positions of the two circular holes b500, wrapping the threaded connecting rod 52 to provide guidance and support for it. A threaded connecting rod 52 is movably connected inside the circular shell 51. The threaded end of the threaded connecting rod 52 sequentially passes through the circular hole b500 and the circular hole a400 and is threadedly connected to the inner threaded fixing block 41 for connecting and fastening the first semi-circular heat preservation cover 2 and the second semi-circular heat preservation cover 3 to ensure their stability. An annular anti-disengagement block 520 is provided on the outer wall of the threaded connecting rod 52, and the top of the annular anti-disengagement block 520 abuts against the bottom of the second strip plate 50 to prevent the second strip plate 50 from moving downward after connection, providing a fixation guarantee.

[0031] In this embodiment, the first semi-circular heat preservation cover 2 includes a first heat preservation layer 6, a heat insulation and reflection layer 7, a second heat preservation layer 8, a moisture-proof isolation layer 9, and an outer protection layer 10 arranged in sequence from inside to outside. The second semi-circular heat preservation cover 3 has the same structure as the first semi-circular heat preservation cover 2. The first heat preservation layer 6 is made of mineral wool to form a complete heat preservation layer. The heat insulation and reflection layer 7 is located outside the first heat preservation layer 6 and is tightly covered with an aluminum foil coil. The second heat preservation layer 8 uses an aerogel material and is covered on the heat insulation and reflection layer 7 by means of fitting or spraying. The moisture-proof isolation layer 9 uses a high-density polyethylene film and is tightly wrapped outside the second heat preservation layer 8. The outer protection layer 10 uses a cross-linked polyethylene material to provide overall structural protection. The first heat preservation layer 6, the heat insulation and reflection layer 7, the second heat preservation layer 8, the moisture-proof isolation layer 9, and the outer protection layer 10 respectively form the multi-layer structure of the heat preservation cover, providing heat preservation, heat insulation, moisture-proof, and protection functions from inside to outside, ensuring the efficient heat transfer of the heating pipe body 1 and the adaptability to the external environment.

[0032] Specifically, the bottom end of the threaded connecting rod 52 passes through the bottom of the inner wall of the circular shell 51 to the outside, and a knob 521 is provided at the bottom end of the threaded connecting rod 52 for manually adjusting and fastening the threaded connecting rod 52, facilitating quick disassembly and assembly.

[0033] Furthermore, when the bottom of the annular anti-detachment block 520 is in contact with the bottom of the inner wall of the circular shell 51, the threaded end of the threaded connecting rod 52 is located within the circular hole b500, avoiding affecting the preliminary docking of the first strip plate 40 and the second strip plate 50.

[0034] Furthermore, two positioning holes 401 arranged symmetrically left and right are opened at the bottom of the first strip plate 40, and two positioning blocks 53 arranged symmetrically left and right are provided at the top of the second strip plate 50. The two positioning blocks 53 are respectively inserted into the two positioning holes 401 to ensure the precise docking and preliminary position fixation between the first strip plate 40 and the second strip plate 50.

[0035] Furthermore, two L-shaped movable plates 42 that can be adjusted back and forth are provided at the top of the first strip plate 40. A support convex block 420 is provided at the bottom inside the L-shaped movable plate 42. The top of the support convex block 420 abuts against the bottom of the second strip plate 50 to provide additional support and positioning. After the preliminary docking of the first strip plate 40 and the second strip plate 50, the L-shaped movable plates 42 and the support convex blocks 420 can be used to initially fix the positions of the first strip plate 40 and the second strip plate 50, avoiding the separation of the first semi-circular heat preservation cover 2 and the second semi-circular heat preservation cover 3.

[0036] Further, two waist-shaped holes 421 arranged symmetrically left and right are formed in the top of the L-shaped moving plate 42. A fixing bolt 43 is connected in the waist-shaped hole 421. A threaded groove 402 for threaded connection of the fixing bolt 43 is formed in the top of the first strip-shaped plate 40. The fixing bolt 43 limits the position of the L-shaped moving plate 42, enabling the L-shaped moving plate 42 to move back and forth. During installation, first move the L-shaped moving plate 42 away from the first semi-circular heat insulation cover 2 to prevent the supporting bump 420 from obstructing the movement of the second strip-shaped plate 50 towards the first strip-shaped plate 40.

[0037] When the heat supply pipe with a heat insulation structure of this embodiment is in use, ensure that the heat supply pipe body 1 is installed and in the correct position. Then, wrap the first semi-circular heat insulation cover 2 and the second semi-circular heat insulation cover 3 outside the heat supply pipe body 1, align the first strip-shaped plate 40 on the first docking member 4 with the second strip-shaped plate 50 on the second docking member 5, and insert the two positioning blocks 53 into the two positioning holes 401 respectively to ensure the precise docking and preliminary position fixation between the first strip-shaped plate 40 and the second strip-shaped plate 50. Then, push the L-shaped moving plate 42 towards the first semi-circular heat insulation cover 2 so that the top of the supporting bump 420 abuts against the bottom of the second strip-shaped plate 50 to provide additional support and positioning, thereby initially fixing the positions of the first strip-shaped plate 40 and the second strip-shaped plate 50 and preventing the separation of the first semi-circular heat insulation cover 2 and the second semi-circular heat insulation cover 3. Then, sequentially pass the threaded end of the threaded connecting rod 52 through the circular hole b500 and the circular hole a400 and thread it into the internal thread fixing block 41. The annular anti-disengagement block 520 abuts against the bottom of the second strip-shaped plate 50 to prevent its movement, thereby realizing the connection and fastening of the first semi-circular heat insulation cover 2 and the second semi-circular heat insulation cover 3 and ensuring its stability. Through these steps, this structure can effectively reduce heat loss, provide efficient heat insulation, and ensure the stability and durability of the heat supply pipe.
