Detailed Implementation

[0030] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0031] like Figures 1 to 7 As shown, a quick-installation and disassembly pipe insulation device includes several male insulation sleeves 1 and several female insulation sleeves 2. Adjacent male insulation sleeves 1 are connected by meshing with female insulation sleeves 2. The male and female insulation sleeves 1 are installed alternately. Each male insulation sleeve 1 includes internal fitting teeth 3 and two semi-ring male insulation sleeves 4. One side of each semi-ring male insulation sleeve 4 is hinged to the other, forming a half-fit structure that can fit onto the pipe, making installation simple and quick. Both ends of each semi-ring male insulation sleeve 4 are provided with internal fitting teeth 3. The internal fitting teeth 3 at the same end of the two semi-ring male insulation sleeves 4 interlock to form a circular convex fitting tooth. The female insulation sleeve 2 includes external fitting teeth 5 and two semi-ring female insulation sleeves 6. The two semi-ring female insulation sleeves 6 are hinged together on one side. Both ends of the semi-ring female insulation sleeves 6 are provided with external fitting teeth 5. The external fitting teeth 5 at the same end of the two semi-ring female insulation sleeves 6 are engaged to form a circular concave fitting tooth. The convex fitting tooth is meshed and fitted in the concave fitting tooth. The male section insulation sleeve 1 and the female section insulation sleeve 2, which adopt a half structure, are conveniently fitted onto the pipeline. The connection between the male section insulation sleeve 1 and the female section insulation sleeve 2 is achieved through the meshing of the convex fitting tooth and the concave fitting tooth, which can achieve a perfect fit. A detachable sealed connection is formed at both ends of the male section insulation sleeve 1 and the female section insulation sleeve 2, which ensures the continuity of the structure, as well as the tight seal of the male section insulation sleeve 1 and the female section insulation sleeve 2 and the circumferential insulation capacity of the insulation device.

[0032] Furthermore, how to 1 to Figure 3As shown, the inner fitting tooth 3 comprises a male section tooth body 7 and an outer trapezoidal tooth 8, one end of the male section tooth body 7 is detachably connected with the half ring male heat preservation sleeve 4, the outer trapezoidal tooth 8 is fixed on the outer wall of the male section tooth body 7, the outer wall of the male section tooth body 7 is provided with an outer trapezoidal groove 9, and the outer trapezoidal groove 9 is located between the half ring male heat preservation sleeve 4 and the outer trapezoidal tooth 8; the outer fitting tooth 5 comprises a female section tooth body 10 and an inner trapezoidal tooth 11, one end of the male section tooth body 7 is detachably connected with the half ring female heat preservation sleeve 6, the inner trapezoidal tooth 11 is fixed on the inner wall of the female section tooth body 10, the inner wall of the female section tooth body 10 is provided with an inner trapezoidal groove 12, and the inner trapezoidal groove 12 is located between the half ring female heat preservation sleeve 6 and the inner trapezoidal tooth 11; the inner trapezoidal tooth 11 is engaged and matched in the outer trapezoidal groove 9, and the outer trapezoidal tooth 8 is engaged and matched in the inner trapezoidal groove 12. The convex fitting tooth and the concave fitting tooth have two sealing surfaces, which are a labyrinth fitting tooth structure. Due to the particularity of the labyrinth fitting tooth structure, the male section heat preservation sleeve 1 and the female section heat preservation sleeve 2 are also guaranteed to be tightly sealed, and have strong sealing strength.

[0033] In some embodiments, as Figure 1 、 Figure 4 and Figure 5As shown, because the female section heat preservation sleeve 2 is fitted on the male section heat preservation sleeve 1, the female section heat preservation sleeve 2 is fitted on the male section heat preservation sleeve 1, and the female section heat preservation sleeve 2 is fitted on the male section heat preservation sleeve 1. When the detection position is located at the female section heat preservation sleeve 2, the half-ring female heat preservation sleeve 6 is directly opened, and the disassembly is simple and fast. If the detection position is located at the male section heat preservation sleeve 1, because the female section heat preservation sleeve 2 is buckled on the male section heat preservation sleeve 1, the female section heat preservation sleeve 2 needs to be opened at both ends of the male section heat preservation sleeve 1 to open the half-ring male heat preservation sleeve 4. On the one hand, the male section heat preservation sleeve 1 is not changed, and on the other hand, the exposed area of the pipeline is increased, which affects the heat preservation effect of the pipeline. Therefore, the structure of the male section heat preservation sleeve 1 needs to be designed separately to ensure that it can be disassembled separately. To this end, the following structure is designed. The inner wall of the half-ring male heat preservation sleeve 4 at both ends is fixed with an L-shaped fastener 13, the outer wall of the male section tooth body 7 is provided with a containing groove 14, and the containing groove 14 is provided with a limiting groove 15. The L-shaped fastener 13 is located in the containing groove 14, and one end of the bottom of the L-shaped fastener 13 is adapted in the limiting groove 15. The L-shaped fastener 13 includes a vertical rod 16 and a horizontal rod 17, and the vertical rod 16 and the horizontal rod 17 are connected in the shape of "L". One end of the horizontal rod 17 away from the vertical rod 16 is adapted in the limiting groove 15. When the horizontal rod 17 is adapted in the limiting groove 15, the outer wall of the male section tooth body 7 is fitted with the inner wall of the half-ring male heat preservation sleeve 4, and the half-ring male heat preservation sleeve 4 and the male section tooth body 7 are designed as a detachable structure, so that when the male section heat preservation sleeve 1 needs to be disassembled separately, the half-ring male heat preservation sleeve 4 and the male section tooth body 7 only need to be separated. The half-ring male heat preservation sleeve 4 is not buckled in the female section heat preservation sleeve 2, so the half-ring male heat preservation sleeve 4 is not affected by the female section heat preservation sleeve 2, so it can be disassembled from the male section tooth body 7 separately, without the need to disassemble the female section heat preservation sleeve 2 at both ends. Thus, the disassembly of the male section heat preservation sleeve 1 becomes simple and fast, and the exposed area of the pipeline is reduced, and the influence on the pipeline heat preservation is minimized. The specific process is as follows. The L-shaped fastener of the half-ring male heat preservation sleeve 4 is inserted into the containing groove 14, then the half-ring male heat preservation sleeve 4 or the male section tooth body 7 is rotated, the L-shaped fastener 13 is adapted in the limiting groove 15, the installation of the half-ring male heat preservation sleeve 4 and the male section tooth body 7 is completed, and the outer wall of the male section tooth body 7 is fitted with the inner wall of the half-ring male heat preservation sleeve 4 to form a sealing surface, so that the detachable connection of the half-ring male heat preservation sleeve 4 and the male section tooth body 7 does not affect the sealing and heat preservation performance. Then, the two half-ring male heat preservation sleeves 4 are buckled to form the male section heat preservation sleeve 1, which is fitted on the pipeline. When the male section heat preservation sleeve 1 needs to be disassembled, because the male section tooth body 7 is fitted in the female section heat preservation sleeve 2, when the male section heat preservation sleeve 1 is rotated, the male section tooth body 7 does not deflect, so that the L-shaped fastener 13 is separated from the limiting groove 15 and located in the containing groove 14. Finally, the half-ring male heat preservation sleeve 4 is pulled up along the hinge position to complete the disassembly of the male section heat preservation sleeve 1, so that the male section heat preservation sleeve 1 can be disassembled separately, and the disassembly operation is simple and fast.It is worth noting that the direction of the L-shaped fastener 13 on the two half-ring male heat preservation sleeves 4 adapting the limiting groove 15 is along the rotation direction of the male section heat preservation sleeve 1, so that when the male section heat preservation sleeve 1 is rotated, the L-shaped fasteners on the two half-ring male heat preservation sleeves 4 are adapted to the corresponding limiting grooves 15 or are separated from the corresponding limiting grooves 15, thereby ensuring that the male section heat preservation sleeve 1 can be smoothly and individually disassembled.

[0034] Further, as shown in Figure 5 , the top of the end of the horizontal rod 17 away from the vertical rod 16 is obliquely fixed with an elastic sheet 18, the height of the elastic sheet 18 gradually increases along the direction close to the vertical rod 16, the elastic sheet 18 is in a pressed-down state in the limiting groove 15, the elastic sheet 18 is used to make the horizontal rod 17 transitionally adapt in the limiting groove 15, so that the connection of the half-ring male heat preservation sleeve 4 and the male section tooth body 7 is more stable and is not easy to be separated under the action of the outside world, manual intervention is needed to make the horizontal rod 17 separate from the limiting groove 15, thereby ensuring the stability of the connection of the male section heat preservation sleeve 1.

[0035] In some embodiments, as shown in Figure 6 and Figure 7 , the two half-ring male heat preservation sleeves 4 and the two half-ring female heat preservation sleeves 6 are hingedly connected through a plurality of hinges 19, the plurality of hinges 19 are uniformly distributed along the axial direction of the male section heat preservation sleeve 1, the opening of the hinge 19 is greater than 180°, so as to facilitate the installation, fitting and disassembly work of various pipelines, the modular length of the male section heat preservation sleeve 1 is 1500mm, each section is assembled and connected by three hinges 19, the modular length of the female section heat preservation sleeve 2 is also 1500mm, each section is also assembled and connected by three hinges 19, thereby realizing the hinged connection of the two half-ring male heat preservation sleeves 4 and the two half-ring female heat preservation sleeves 6, the two half-ring male heat preservation sleeves 4 and the two half-ring female heat preservation sleeves 6 are detachably connected through a fixing fastener 20, so as to facilitate the buckling of the two half-ring male heat preservation sleeves 4 together to form the male section heat preservation sleeve 1 and the buckling of the two half-ring female heat preservation sleeves 6 together to form the female section heat preservation sleeve 2.

[0036] In some embodiments, the half-ring male heat preservation sleeve 4 comprises a die-casting heat preservation body 21 and an outer metal plate 22 fixedly wrapped on the outer wall of the die-casting heat preservation body 21, and the structure of the half-ring female heat preservation sleeve 6 is the same as that of the half-ring male heat preservation sleeve 4. The die-casting heat preservation body 21 is formed by die-casting calcium carbonate material, and the thickness of the die-casting heat preservation body 21 is selected according to the heat preservation temperature, so that the die-casting heat preservation body 21 has good heat preservation effect and can meet the needs of different heat preservation temperatures. One die-casting heat preservation body 21 is fixedly provided with an outer clamping body 23 on the side away from the hinge position, and the other die-casting heat preservation body 21 is fixedly provided with an inner clamping body 24 on the side away from the hinge position. When the two half-ring male heat preservation sleeves 4 are completely buckled, the outer clamping body 23 and the inner clamping body 24 are in contact and adapt to the form of a boss. The half-ring female heat preservation sleeve 6 is also connected by a die-casting heat preservation body 21 and an outer metal plate 22. The two half-ring female heat preservation sleeves 6 are also respectively provided with an outer clamping body 23 and an inner clamping body 24. The interfaces on both sides of the male section heat preservation sleeve 1 and the interfaces on both sides of the female section heat preservation sleeve 2 are connected by the outer clamping body 23 and the inner clamping body 24 in contact and adaptation to the form of a boss. The side sealing structure of the fixed buckle 20 is designed in the form of a boss. The connecting side surface of the male section heat preservation sleeve 1 and the connecting side surface of the female section heat preservation sleeve 2 both have high sealing performance. The side sealing structure of the hinge 19 is designed by interference fit to ensure the axial heat preservation capacity of the male section heat preservation sleeve 1 and the female section heat preservation sleeve 2. Therefore, the sealing connection structure is designed according to the structural characteristics of the male section heat preservation sleeve 1 and the female section heat preservation sleeve 2 and the connection characteristics of the male section heat preservation sleeve 1 and the female section heat preservation sleeve 2. The structure is simple and easy to install and disassemble, and also has good sealing performance, thereby improving the heat preservation effect.

[0037] In summary, the specific installation and disassembly process is as follows: before installation, the surface of the specified pipeline is simply treated to remove foreign matter on the surface of the pipeline, the male section heat preservation sleeve 1 is taken out, the fixed buckle 20 is opened, the male section heat preservation sleeve 1 is tightly attached to the outer surface of the pipeline, the outer clamping body 23 and the inner clamping body 24 connected to the two ends of the die-casting heat preservation body 21 are aligned, the fixed buckle 20 is closed to ensure that the male section heat preservation sleeve 1 is attached to the pipeline, the female section heat preservation sleeve 2 is taken out, and each of the two sections is installed on the axial ends of the male section heat preservation sleeve 1 that has been installed in place. The female section heat preservation sleeve 2 is opened, the male section heat preservation sleeve 2 is aligned with the male section heat preservation sleeve 2 on the left and right ends, the position of the female section heat preservation sleeve 2 is adjusted by rotating, it is ensured that the joint of each female section heat preservation sleeve 2 and the joint of the male section heat preservation sleeve 1 on the adjacent pipeline are not on the same line, the female section heat preservation sleeve 2 is closed, the outer clamping body 23 and the inner clamping body 24 connected to the two ends of the die-casting heat preservation body 21 are aligned, the fixed buckle 20 on the female section heat preservation sleeve 2 is not locked, the male section heat preservation sleeve 1 and the female section heat preservation sleeve 2 are alternately installed on the upper and lower ports of the pipeline, until the installation of the heat preservation layer of the whole pipeline is completed, and finally the fixed buckle 20 on the female section heat preservation sleeve 2 is buckled to install the heat preservation device. The whole installation process is convenient to operate and saves time. It does not require a large amount of manpower and material resources, nor large-scale tooling and equipment.

[0038] In the pipeline periodic inspection or overhaul, the heat preservation device can realize fast and convenient installation and disassembly. Before disassembly, the disassembly mode is selected according to the disassembly position, when the disassembly position is the female section heat preservation sleeve 2, the fixed buckle 20 on it is directly opened to take down the female section heat preservation sleeve 2, when the disassembly position is the male section heat preservation sleeve 1, the male section heat preservation sleeve 1 is first rotated to separate the cross rod 17 from the limiting groove 15, and finally the fixed buckle on it is opened to take down the male section heat preservation sleeve 1, so that each male section heat preservation sleeve 1 and the female section heat preservation sleeve 2 can be disassembled separately, the disassembly difficulty and labor intensity are reduced, when the heat preservation device needs to be disassembled as a whole, the two end fixed buckles 20 of the male section heat preservation sleeve 1 and the female section heat preservation sleeve 2 are first opened, then the female section heat preservation sleeve 2 is taken down, and then the male section heat preservation sleeve 1 is taken down, so that the fast disassembly of the heat preservation device is completed without separating the half-ring male heat preservation sleeve 4 from the male section tooth body 7, the male section heat preservation sleeve 1 does not need to be reassembled when the heat preservation device is used again, and the installation difficulty and labor intensity of the heat preservation device are reduced. In the whole life cycle of the pipeline, the fast installation and disassembly pipeline heat preservation device can be repeatedly installed and disassembled, and the use cost is greatly saved.
