Description

Technical Field

[0001] This utility model relates to the field of pipeline insulation technology, and in particular to an external insulation layer structure for thermal power pipelines. Background Technology

[0002] In thermal power plants, equipment such as high-temperature steam pipelines, water supply pipelines, and flue gas ducts need to be covered with external insulation layers to reduce heat loss, ensure operational safety, improve the working environment, and meet energy conservation standards. The existing external insulation layer structure of thermal power pipelines usually uses insulation cotton of fixed thickness, consisting of a single insulation cotton and a fixed outer shell. Thermal power pipelines have different insulation requirements under different operating conditions, and the fixed thickness insulation layer is difficult to take into account the insulation effect under different temperature scenarios. It is also inconvenient to change the thickness of the insulation cotton according to the usage requirements.

[0003] Therefore, it is necessary to design a flexible external insulation layer structure for thermal power pipelines that can adjust the thickness of the insulation cotton according to usage requirements. Utility Model Content

[0004] To overcome the shortcomings of existing thermal power pipeline external insulation layer structures, which typically use insulation cotton of fixed thickness, it is difficult to achieve insulation effects under different temperature scenarios and the thickness of the insulation cotton cannot be changed according to usage requirements. This utility model provides a thermal power pipeline external insulation layer structure that can change the thickness of the insulation cotton according to usage requirements and is flexible in use.

[0005] The technical solution is as follows: an external insulation layer structure for thermal power pipelines, including a fixing frame, a first insulation cotton, a second insulation cotton, a limiting frame, a locking plate, a spring, a limiting plate, fixing screws, and splicing components. The fixing frame has two parts, left and right, with the first insulation cotton connected to the side of each fixing frame that is close to the other. Second insulation cotton is placed on the outer sides of both the upper and lower parts of the fixing frame. A limiting frame is placed in the middle of each fixing frame. Locking plates are slidably connected to both the front and rear parts of the limiting frame. Each locking plate engages with an adjacent fixing frame. A spring connects each locking plate to an adjacent limiting frame. Limiting plates are detachably connected to both the upper and lower parts of the limiting frame via fixing screws. Each limiting plate contacts an adjacent second insulation cotton. The fixing frame is equipped with splicing components for easy splicing and locking.

[0006] As an improvement to the above solution, the first insulation cotton has an arc-shaped structure.

[0007] As an improvement to the above solution, the splicing assembly includes a first splicing block, a second splicing block, a fixing block, a bidirectional screw rod, and a locking block. The first splicing block is connected to the upper and lower right sides of the fixing frame on the left. The second splicing block is connected to the upper and lower left sides of the fixing frame on the right. The fixing block is connected to the side of the first splicing block that is far apart from each other. The fixing block is rotatably connected to the bidirectional screw rod. The locking block is threadedly connected to the front and rear parts of the bidirectional screw rod. The locking block is quickly and smoothly connected to the adjacent first splicing block.

[0008] As an improvement to the above solution, a toggle plate is also included, with toggle plates connected to the outer side of the locking plate.

[0009] As an improvement to the above solution, each of the second assembly blocks has a slot.

[0010] As an improvement to the above solution, the bidirectional lead screw is equipped with docking blocks on both the front and rear sides.

[0011] The present invention has the following advantages: 1. The present invention fits the limiting frame into the middle of the fixed frame, so that the limiting plate and the second insulation cotton are in close contact to limit and fix it. Then, the actuating plate is released, the spring returns to its original state, and the locking plate moves outward and inserts into the fixed frame to quickly lock the limiting frame. By increasing the thickness of the second insulation cotton, the thickness of the insulation cotton can be changed according to the usage requirements, and the use is flexible.

[0012] 2. This utility model involves inserting the second assembly block into the corresponding first assembly block, and then rotating the bidirectional screw to move the locking block under the action of the thread, so that the locking blocks move closer to each other and are inserted into the second assembly block for locking, thus completing the installation of the first insulation cotton. This achieves the effect of convenient splicing and installation, simple operation, and convenient use. Attached Figure Description

[0019] The technical solution will be further described below with reference to specific embodiments. It should be noted that the terms "up," "down," "left," and "right" used in this document refer only to the position of the structure shown in the corresponding drawings. The serial numbers assigned to components in this document, such as "first," "second," etc., are only used to distinguish the described objects and have no sequential or technical meaning. Unless otherwise specified, terms such as "connection" and "linkage" in this application include both direct and indirect connections (linkages).

[0020] A thermal power pipeline external insulation layer structure, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the device includes a fixing frame 1, a first insulation cotton 2, a second insulation cotton 3, a limiting frame 4, a locking plate 10, a toggle plate 11, a spring 12, a limiting plate 13, a fixing screw 14, and a splicing assembly. The fixing frame 1 has two parts, left and right. The first insulation cotton 2 is connected to the side of the fixing frame 1 that is close to each other. The first insulation cotton 2 has an arc-shaped structure. The second insulation cotton 3 is placed on the outer sides of the upper and lower parts of the fixing frame 1. The limiting frame 4 is placed in the middle of the fixing frame 1. The locking plate 10 is slidably connected to the front and rear parts of the limiting frame 4. The locking plate 10 is snapped into the adjacent fixing frame 1. The toggle plate 11 is connected to the outer side of the locking plate 10. The spring 12 is connected between the locking plate 10 and the adjacent limiting frame 4. The limiting plate 13 is detachably connected to the upper and lower parts of the limiting frame 4 through the fixing screw 14. The limiting plate 13 is in contact with the adjacent second insulation cotton 3. The fixing frame 1 is equipped with a splicing assembly.

[0021] like Figure 2 and Figure 3 As shown, the splicing assembly includes a first splicing block 5, a second splicing block 6, a fixing block 7, a bidirectional screw rod 8, and a locking block 9. The first splicing block is connected to the upper and lower right sides of the left fixing frame 1, and the second splicing block 6 is connected to the upper and lower left sides of the right fixing frame 1. The second splicing block 6 has a slot for easy locking. The fixing block 7 is connected to the side of the first splicing block 5 that is far apart from each other. The bidirectional screw rod 8 is rotatably connected to the fixing block 7. The bidirectional screw rod 8 has docking blocks on both the front and rear sides for easy docking and rotation. The locking block 9 is threadedly connected to both the front and rear sides of the bidirectional screw rod 8. The locking block 9 is connected to the adjacent first splicing block in a quick sliding manner.

[0022] When using this utility model, first place the fixing frame 1 on both sides of the thermal power pipeline, so that the second assembly block 6 is inserted into the corresponding first assembly block 5, and then rotate the double-acting screw 8 so that the locking block 9 moves under the action of the thread, so that the locking blocks 9 move closer to each other and are inserted into the second assembly block 6 to lock, thus completing the installation of the first insulation cotton 2, which makes it easy to splice and install, and is simple to operate and convenient to use. When basic insulation is required, insulation is achieved solely by the first insulation cotton 2. When the insulation thickness needs to be increased, the second insulation cotton 3 is placed on the outer sides of the upper and lower parts of the fixed frame 1. Then, the actuating plate 11 is moved inward, the spring 12 contracts, and the locking plate 10 is moved inward. Then, the limiting frame 4 is fitted into the middle of the fixed frame 1. The limiting plate 13 is installed on the upper and lower parts of the limiting frame 4 by the fixing screws 14, so that the limiting plate 13 and the second insulation cotton 3 are in close contact to limit and fix them. Then, the actuating plate 11 is released, the spring 12 returns to its original state, and the locking plate 10 is moved outward and inserted into the fixed frame 1 to quickly lock the limiting frame 4. The thickness is increased by the second insulation cotton 3, so the thickness of the insulation cotton can be changed according to the usage requirements, making it flexible in use.
