[0002] In the operation of steam turbines, the insulation structure is of paramount importance. Traditional insulation structures are complex to install, take a long time to install, are inefficient, and are difficult to inspect and replace later. For example, the multi-layer wrapping design makes it difficult to disassemble. It also has problems such as poor insulation effect, hot spots and gaps, resulting in a large amount of heat loss, the insulation material is prone to deformation at high temperatures and produces toxic substances, short service life and environmentally unfriendly. At the same time, the control of the insulation structure installation process is not convenient enough, making it difficult to meet the requirements of modern industrial production for high efficiency, stability and intelligence; To address the aforementioned technical shortcomings, a solution is provided. Summary of the Invention

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a splicing three-dimensional thermal insulation structure for steam turbines and its quick-installation equipment.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A spliced ​​steam turbine three-dimensional insulation structure includes multiple sets of metal shells formed by spot welding of metal plates, and the interior of the metal shells is filled with insulation pads. The insulation pad is made of glass fiber insulation material, and stainless steel wires are embedded in the glass fiber insulation material to reinforce the structure.

[0005] Furthermore, the multiple sets of metal casings are connected by hooks or fasteners.

[0006] Among them, a quick-installation device for a splicing steam turbine three-dimensional insulation structure is used in the installation process of a splicing steam turbine three-dimensional insulation structure, including a quick-installation frame, an upper insulation structure, a lower insulation structure, and quick-installation components for connecting the upper and lower insulation structures.

[0007] Furthermore, the quick-installation assembly includes several sets of hooks fixedly installed on the two bottom side walls of the upper insulation structure. An arc-shaped top rod is fixedly installed on the top wall of the quick-installation frame below the hooks. A U-shaped pressing plate is provided on the arc-shaped top rod and contacts its top. The U-shaped pressing plates are symmetrically arranged on both sides of the lower insulation structure. The ends of the U-shaped pressing plates are rotatably connected to the top side wall of the lower insulation structure. A connecting post is rotatably provided in the middle of the U-shaped pressing plate through a pin. A buckle ring connected to the hooks is provided above the connecting post.

[0008] Furthermore, the connecting column is inclined from the side near the arc-shaped top rod to the side away from the arc-shaped top rod, moving away from the lower insulation structure.

[0009] Furthermore, a magnet is provided at the bottom of the connecting column, and an iron plate that attracts the magnet is provided on the side wall of the arc-shaped top rod corresponding to the connecting column. A support rod is fixed on the top wall of the end of the U-shaped pressing plate, and the support rod is connected to the upper side wall of the connecting column by a tension spring.

[0010] Furthermore, one side of the arc-shaped top rod is provided with a cylinder that is fixedly connected to the quick-assembly frame. The extended end of the cylinder is provided with a lever column that is rotatably connected to it. Above the cylinder is an H-shaped plate that is rotatably connected to the side wall of the quick-assembly frame. A sliding groove is provided on the bottom side wall of the H-shaped plate, and the sliding groove is movably connected to the lever column.

[0011] Furthermore, the H-shaped plate is inclined from the side closest to the cylinder to the side furthest from the cylinder toward the direction closer to the lower insulation structure.

[0012] Furthermore, the bottom two side walls of the lower insulation structure are symmetrically provided with arc-shaped support seats. Multiple sets of buffer grooves are evenly opened on the side wall of the arc-shaped support seats near the quick-assembly frame. A protruding rod is slidably provided in the buffer groove, and a thrust spring is provided between the top of the protruding rod and the top wall of the buffer groove.

[0013] Furthermore, the bottom wall of the quick-assembly frame is provided with a leather airbag that supports the lower insulation structure. An air inlet pipe and an air outlet pipe are inserted below the leather airbag. A control valve is provided on the outer wall of the air inlet pipe and the outer wall of the air outlet pipe.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example 1: Please refer to Figures 1-8 As shown, the problem of material waste caused by the non-removable insulation structure in the existing technology can be solved by the following solution; This embodiment of a spliced ​​steam turbine three-dimensional insulation structure includes multiple sets of metal shells 011 formed by spot welding of metal plates, and the interior of the metal shells 011 is filled with insulation pads 012. The thermal insulation pad 012 is made of glass fiber insulation material, which contains stainless steel wires for reinforcing the structure.

[0027] Multiple sets of metal casings 011 are connected by hooks or buckles, with 45-degree bevels or stepped overlaps, without creating any gaps or hot spots; To further clarify the above: High-performance fiberglass insulation material, adhesive-free, reinforced with stainless steel wire, with an ultra-long service life, no deformation under long-term high-temperature operation, non-toxic and harmless, no dust pollution, and the outer layer material is waterproof and oil-proof and can be wiped clean. refer to Figures 7-8 As shown, the three-dimensional insulation structure also includes a detachable blanket-type double-wall box insulation structure and a metal reflective double-wall box insulation structure. The detachable blanket-type double-wall box insulation structure consists of a metal shell 011 and an insulation pad 012 that can be attached to the inner wall of the metal shell 011. The metal reflective double-wall box insulation structure consists of a metal shell 011 and a metal arc plate set inside the metal shell 011. The insulation structure is installed according to the equipment differences. Example 2: Please refer to Figures 1-5 As shown, in conjunction with the relevant content in Embodiment 1, the installation process of the spliced ​​steam turbine three-dimensional insulation structure is explained as follows: A quick-assembly device for a splicing steam turbine three-dimensional insulation structure includes a quick-assembly frame 2, an upper insulation structure 01, a lower insulation structure 02, and quick-assembly components connecting the upper insulation structure 01 and the lower insulation structure 02. The quick-installation assembly includes several sets of hooks 51 fixedly installed on the two bottom side walls of the upper insulation structure 01. An arc-shaped top rod 59 is fixedly installed on the top wall of the quick-installation frame 2 below the hooks 51. A U-shaped pressing plate 52 is provided on the arc-shaped top rod 59 and contacts its top. The U-shaped pressing plates 52 are symmetrically arranged on both sides of the lower insulation structure 02. The ends of the U-shaped pressing plates 52 are rotatably connected to the top side wall of the lower insulation structure 02. A connecting post 56 is rotatably provided in the middle of the U-shaped pressing plate 52 through a pin. A buckle ring 55 connected to the hooks 51 is provided above the connecting post 56. That is, through the design of quick-installation components such as hooks 51, buckles 55 and U-shaped pressing plates 52, the upper insulation structure 01 and the lower insulation structure 02 can be quickly connected and fixed, which significantly improves installation efficiency and facilitates later maintenance and replacement. The connecting column 56 is inclined from the side near the arc-shaped top rod 59 to the side away from the arc-shaped top rod 59, moving away from the lower insulation structure 02; A magnet 58 is provided at the bottom of the connecting column 56. An iron plate 57 that attracts the magnet 58 is provided on the side wall of the arc-shaped top rod 59 corresponding to the connecting column 56. A support rod 53 is fixed on the top wall of the end of the U-shaped pressing plate 52. The support rod 53 is connected to the upper side wall of the connecting column 56 by a tension spring 54. That is, by using the attraction between magnet 58 and iron plate 57, and with the assistance of tension spring 54, the stability of connecting column 56 during installation is ensured, accidental detachment during connection is prevented, and the reliability of the overall structure is improved. A cylinder 511 is fixedly connected to the quick-assembly frame 2 on one side of the arc-shaped top rod 59. A lever column 513 is rotatably connected to the extended end of the cylinder 511. An H-shaped plate 510 is rotatably connected to the side wall of the quick-assembly frame 2 above the cylinder 511. A sliding groove 512 is opened on the bottom side wall of the H-shaped plate 510. The sliding groove 512 is movably connected to the lever column 513. The H-shaped plate 510 is inclined from the side closest to the cylinder 511 to the side furthest from the cylinder 511 towards the lower insulation structure 02; the H-shaped plate 510 is positioned in an arc shape. The bottom two side walls of the lower insulation structure 02 are symmetrically provided with arc-shaped support seats 61. Multiple sets of buffer grooves 63 are evenly opened on the side wall of the arc-shaped support seat 61 near the quick-assembly frame 2. A protruding rod 62 is slidably provided in the buffer groove 63. A thrust spring 64 is provided between the top of the protruding rod 62 and the top wall of the buffer groove 63. That is, the design of the arc-shaped support 61 and the thrust spring 64 provides good buffer protection for the lower insulation structure 02, keeps it stable during descent, and avoids damage caused by impact; The quick-assembly frame 2 has a leather airbag 4 on its bottom wall that supports the lower insulation structure 02. An air inlet pipe and an air outlet pipe are inserted below the leather airbag 4. A control valve is provided on the outer wall of the air inlet pipe and a control valve is provided on the outer wall of the air outlet pipe. After gas is introduced into the air inlet pipe by an external inflation device, it enters the air bladder 4 to inflate the air bladder 4. The gas inside the air bladder 4 is then expelled by opening the control valve above the air outlet pipe. The bottom of the quick-installation frame 2 is provided with an installation frame 3 that connects to an external lifting structure; The quick-installation steps for the upper insulation structure 01 and the lower insulation structure 02 are explained based on the above content: First, the upper insulation structure 01 is installed on the top wall of the turbine pipeline. Then, the quick-installation frame 2 with the lower insulation structure 02 installed is moved to the bottom of the upper insulation structure 01 by the lifting equipment to ensure that the upper insulation structure 01 and the lower insulation structure 02 are aligned and that the buckle ring 55 and the hook 51 are corresponding. By opening the control valve above the air outlet pipe, a small amount of gas inside the air bag 4 is discharged, so that the top of the lower insulation structure 02 moves to the bottom of the quick-installation frame 2. At this time, the arc-shaped top rod 59 provides an upward push to the U-shaped pressing plate 52, so that the connecting column 56 connected to the arc-shaped top rod 59 by the magnet 58 is separated from the arc-shaped top rod 59. Under the action of the tension spring 54, the top of the connecting column 56 moves towards one side of the support rod 53, so that several sets of buckle rings 55 are simultaneously locked on the corresponding hooks 51. After the buckle ring 55 is engaged with the hook 51, the quick-installation frame 2 is moved downward by the external lifting device. When the arc-shaped top rod 59 moves below the connecting column 56, the extension end of the control cylinder 511 extends, and the lever moves upward in the slide groove 512, providing upward thrust to the end of the H-shaped plate 510 until the H-shaped plate 510 is adjusted to a horizontal position. Then, the quick-installation frame 2 continues to move downward, so that the H-shaped plate 510 provides downward thrust to the outer wall of the U-shaped pressing plate 52, thereby enabling multiple sets of U-shaped pressing plates 52 to be engaged simultaneously, realizing the quick installation of the upper insulation structure 01 and the lower insulation structure 02. The following explains the quick-installation steps for the upper insulation structure 01 and the lower insulation structure 02: When the lower insulation structure 02 is installed on the quick-installation frame 2, the two arc-shaped support seats 61 and the inflated air bladder 4 support it, so that the top of the lower insulation structure 02 is level with the top of the quick-installation frame 2. When the airbag 4 exhausts air through the air outlet pipe, the lower insulation structure 02 moves downward, and the arc-shaped support seats 61 on both sides move downward simultaneously. That is, the buffer groove 63 moves downward along the protruding rod 62 to ensure the stability of the descent of the lower insulation structure 02. The following supplementary explanation is provided regarding the quick-installation steps for the upper insulation structure 01 and the lower insulation structure 02: The action of cylinder 511 can be controlled by PLC controller. The lifting and lowering of quick-assembly frame 2 can be achieved by hydraulic lifting platform or other lifting equipment. These devices are usually equipped with height adjustment device and safety locking mechanism to ensure the stability and safety of quick-assembly frame 2 during the lifting process. The lifting operation can be completed by remote control or on-site operation, improving work efficiency and operation convenience. In summary: By using high-performance glass fiber insulation material, the three-dimensional insulation structure is ensured to have an ultra-long service life, remain undeformed at high temperatures, and be environmentally friendly and harmless. The metal casing 011 is tightly connected, eliminating gaps and hot spots, improving insulation effect and equipment stability. At the same time, the height of the lower insulation structure 02 is adjusted using the air bladder 4, and the quick engagement of the hook 51 and the buckle ring 55 is achieved with the help of the magnet 58 and the tension spring 54. The cylinder 511 and the H-shaped plate 510 work together to ensure a firm buckle, realizing the quick connection and fixation of the upper insulation structure 01 and the lower insulation structure 02, significantly improving installation efficiency and facilitating maintenance and replacement.
