Description

Technical Field

[0001] This application belongs to the field of pipeline sealing structures, and more specifically, relates to a rainproof sealing structure for a gas turbine intake system pipeline that passes through a wall. Background Technology

[0002] During operation, a gas turbine requires a continuous supply of clean air from the outside to ensure complete fuel combustion. If unfiltered air impurities enter the main unit, it could potentially break the blades. Therefore, an air filtration system, known as the gas turbine intake system, is connected to the gas turbine's intake end.

[0003] The intake system generally consists of two parts: a filter chamber for installing filters and a gas flow pipeline. Depending on the project site, the filter chamber is usually installed outdoors to obtain outside air, while the pipeline connected to the gas turbine intake port is usually installed indoors together with the gas turbine. Therefore, the entire gas turbine intake system will pass through the walls of the foundation civil engineering in the pipeline section.

[0004] In related technologies, the pipes of the air intake system are usually sealed at the wall penetration points to prevent rainwater from entering the room. However, existing seals are usually made of flexible rubber materials, such as rubber sleeves, which can seal the gap between the pipe and the wall. However, the service life of rubber materials will be shortened under wind, sun and rain immersion, affecting their sealing performance. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this application provides a wall-penetrating rainproof sealing structure for gas turbine intake system pipelines, aiming to solve the problem that existing rubber seals for gas turbine intake system pipelines suffer from shortened service life and reduced sealing performance under wind, sun, and rain immersion.

[0006] This application provides a wall-penetrating rainproof sealing structure for a gas turbine intake system pipeline, specifically including a pre-embedded frame assembly and a positioning sealing installation assembly;

[0007] The embedded frame assembly includes several embedded plates, which are arranged around the outer periphery of the positioning and sealing installation assembly and are sealed and fixedly connected to the positioning and sealing installation assembly. The positioning and sealing installation assembly is fixed to the wall through the embedded plates.

[0008] The positioning and sealing installation assembly is fixedly connected to the periphery of the pipe, and an air duct for connecting the indoor and outdoor areas is also provided between the positioning and sealing installation assembly and the pipe.

[0009] Compared with the prior art, the above-described technical solution conceived in this application achieves a rigid structure to seal the pipe and the wall by setting up a pre-embedded frame component and a positioning sealing installation component, which can prevent rainwater from entering, and has high strength and longer service life. At the same time, the set air duct can realize indoor and outdoor air circulation.

[0010] As a further preferred embodiment, the embedded plate is provided with a plurality of embedded parts, the embedded plate is fixedly connected to the wall by the embedded parts, and the side of the embedded plate away from the embedded parts is located outside the wall.

[0011] By adopting the above technical solution, when pouring the wall, the embedded parts are poured into the inside of the wall, so that the embedded plate is fixed on the wall and the connection is stable, which facilitates the stable installation of the positioning and sealing installation components.

[0012] As a further preferred embodiment, each of the embedded plates is provided with a plurality of vent holes along its length, and the vent holes are all located on the edge of the embedded plate away from the positioning and sealing mounting assembly.

[0013] By adopting the above technical solution, air bubbles between the wall and the embedded plate during the wall pouring process can be discharged from the vent hole, further improving the installation stability of the embedded plate, and the positioning and sealing installation component will not interfere with the vent hole during installation.

[0014] As a further preferred embodiment, the positioning and sealing installation assembly includes an outer sealing connector and an inner sealing connector. The outer sealing connector has an annular structure, and its outer periphery is sealed and fixedly connected to the outdoor side of the embedded plate. The pipe passes through the middle of the outer sealing connector, and a first opening is formed between the top of the pipe and the outer sealing connector. The outer sealing connector is sealed and fixedly connected to both sides and the bottom of the pipe through the inner sealing connector.

[0015] By adopting the above technical solution, the outer sealing connector supports and positions the pipeline through the inner sealing connector, and the pipeline has a larger force-bearing area, resulting in better support. Air can flow between indoor and outdoor spaces through the first opening.

[0016] As a further preferred embodiment, the inner circumferential side of the outer sealing connector has a raised structure facing the outside.

[0017] By adopting the above technical solution, the external sealing connector is designed with a raised structure to facilitate rainwater flow.

[0018] As a further preferred embodiment, the inner sealing connector includes a first sealing element, which is fixedly connected to the bottom and both sides of the pipe by screws. Waterproof sealant is filled between the first sealing element and the pipe. The outer side of the first sealing element is sealed and fixedly connected to the outer sealing connector. The first sealing element is bent to the side facing the outside to cover the connection between the first sealing element and the outer sealing connector.

[0019] By adopting the above technical solution, the first sealing element is set on the outside of the pipeline. While the outer sealing connector supports the pipeline, the first sealing element seals the bottom and both sides of the pipeline. At the same time, it can increase the stress surface of the pipeline, making the support of the pipeline more stable and avoiding damage caused by concentrated stress on the pipeline. Furthermore, the bending of the first sealing element covers the connection between the first sealing element and the outer sealing connector, making the connection between the first sealing element and the outer sealing connector more stable and stronger.

[0020] As a further preferred embodiment, the inner sealing connector further includes a second sealing member, the second sealing member being located at the top of the pipe and fixedly connected to the inner side of the outer sealing connector, the bottom of the second sealing member being fixedly connected to the pipe, and a second opening being formed between the top of the second sealing member and the outer sealing connector, and an air guiding channel being formed between the first opening and the second opening.

[0021] By adopting the above technical solution, the first opening is blocked by the second sealing element, so that the air guide channel forms a vertical channel. Air enters from the first opening at the bottom and exits from the second opening at the top, realizing air flow, while preventing rainwater from entering the room from the first opening.

[0022] As a further preferred embodiment, the top of the second seal is provided with a bent baffle on the side closer to the outer sealing connector.

[0023] By adopting the above technical solution, the bending baffle can further block rainwater and reduce the amount of rainwater entering the room due to splashing.

[0024] As a further preferred embodiment, the embedded part is a V-shaped metal connector, and both ends of the embedded part are fixedly connected to the embedded plate.

[0025] By adopting the above technical solution, after the embedded parts are poured into the wall, the mortar can flow between the embedded parts and the embedded plate. After the mortar solidifies, the connection strength between the embedded parts and the wall is higher, making the installation of the embedded plate more stable, thereby improving the installation stability of the sealing structure.

[0026] As a further preferred embodiment, the outer surfaces of both the embedded frame assembly and the positioning sealing installation assembly are coated with an anti-rust coating.

[0027] By adopting the above technical solution, the anti-rust coating can reduce the corrosion of the embedded frame components and positioning sealing installation components, thereby improving the service life of the structure.

[0028] In summary, compared with the prior art, the technical solutions conceived in this application have the following main technical advantages:

[0029] 1. The gas turbine intake system of this application uses a pre-embedded frame assembly and a positioning sealing installation assembly to achieve a rigid structure between the pipe and the wall, which can prevent rainwater from entering. The sealing structure has high strength and a longer service life. At the same time, the air guide channel can realize indoor and outdoor air circulation.

[0030] 2. By setting the first sealing element on the outside of the pipe, the outer sealing connector supports the pipe while the first sealing element seals the bottom and sides of the pipe. The first opening is located at the top of the pipe to allow air flow. At the same time, the first sealing element can increase the stress surface of the pipe, making the support of the pipe more stable and avoiding damage caused by concentrated stress on the pipe.

[0031] 3. The second seal blocks the first opening, making the air duct a vertical channel. Air enters from the first opening at the bottom and exits from the second opening at the top, achieving airflow while preventing rainwater from entering the room through the first opening.

[0040] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0041] This application discloses a rainproof sealing structure for gas turbine intake system pipelines that penetrate walls.

[0042] Reference Figure 1 A rainproof sealing structure for a gas turbine intake system pipe that penetrates a wall is disclosed, used to provide a rainproof seal between a wall 3 and a pipe 4. The structure includes a pre-embedded frame assembly 1 and a positioning sealing installation assembly 2. The pre-embedded frame assembly 1 is fixedly installed on the wall 3 during the pouring of the wall. The positioning sealing installation assembly 2 is fixedly connected around the periphery of the pipe 4 and is fixedly installed on the wall 3 via the pre-embedded frame assembly 1. An air guide channel 5 is also provided between the positioning sealing installation assembly 2 and the pipe 4 to connect indoor and outdoor airflow. This application uses a rigid structure to achieve a seal between the pipe 4 and the wall 3, preventing rainwater ingress, and providing high strength and a longer service life. Furthermore, the outer surfaces of both the pre-embedded frame assembly 1 and the positioning sealing installation assembly 2 are coated with an anti-rust coating, preventing rust during use and further extending the service life of the sealing structure.

[0043] In this embodiment, the embedded frame assembly 1 includes four embedded plates 11. Each embedded plate 11 has several embedded parts 12 fixedly connected to one side. The embedded parts 12 are V-shaped metal connectors, and both ends of the embedded parts 12 are fixedly connected to the embedded plates 11. During installation, the embedded plates 11 are fixedly connected to the wall 3 via the embedded parts 12. Specifically, when pouring the wall 3, the embedded parts 12 are poured inside the wall 3, and the side of the embedded plate 11 facing away from the embedded parts 12 is located outside the wall 3, specifically on the outdoor side. After the embedded parts 12 are poured into the wall 3, the mortar can flow between the embedded parts 12 and the embedded plates 11. To prevent the embedded plates 11 from contacting the mortar during pouring... There are air bubbles between the mortar. Each embedded plate 11 has several vent holes 111 along its length. The vent holes 111 are all located on the edge of the embedded plate 11 away from the positioning and sealing installation component 2. When the mortar is poured, the air bubbles can be discharged from the vent holes 111. After the mortar solidifies, the connection strength between the embedded part 12 and the wall 3 is higher, making the installation of the embedded plate 11 more stable. Among them, four embedded plates 11 are connected end to end to form a ring structure, which is arranged around the outer periphery of the positioning and sealing installation component 2 and is sealed and fixedly connected to the positioning and sealing installation component 2. The positioning and sealing installation component 2 is fixed to the wall 3 through the embedded plates 11, thereby making the installation of the positioning and sealing installation component 2 more stable.

[0044] In this embodiment, the positioning and sealing installation assembly 2 includes an outer sealing connector 21 and an inner sealing connector 22. The outer sealing connector 21 has a rectangular ring structure, and the four sides of the outer sealing connector 21 correspond to the positions of the four embedded plates 11. The outer peripheral side of the outer sealing connector 21 has a raised structure on the outdoor side to facilitate the flow of rainwater. The outer peripheral side of the outer sealing connector 21 is sealed and fixedly connected to the outdoor side of the embedded plate 11. Specifically, the outer sealing connector 21 is welded to the embedded plate 11, and the space between the outer sealing connector 21 and the embedded plate 11 is filled with sealing adhesive to prevent water seepage at the weld failure point. The pipe 4 passes through the middle of the outer sealing connector 21, and a first opening is formed between the top of the pipe 4 and the outer sealing connector 21, through which air can flow.

[0045] The outer sealing connector 21 is sealed and fixedly connected to both sides and the bottom of the pipe 4 through the inner sealing connector 22. Specifically, the inner sealing connector 22 includes a first sealing element 221 made of stainless steel plate bent into a U-shape. The first sealing element 221 is fixedly connected to the bottom and both sides of the pipe 4 by screws. Waterproof sealant is filled between the first sealing element 221 and the pipe 4. The outer side of the first sealing element 221 is sealed and fixedly connected to the outer sealing connector 21 by welding. The first sealing element 221 is bent to the side facing the outside, forming an L-shaped cross-section. The connection between the first sealing element 221 and the outer sealing connector 21 is covered. The bent part of the first sealing element 221 can be welded to the outer sealing connector 21 to further improve the connection strength. The outer sealing connector 21 can position and support the pipe 4 through the first sealing element 221. At the same time, the first sealing element 221 can increase the stress surface of the pipe 4, making... The support for pipe 4 is more stable, and the concentrated stress on pipe 4 is avoided, which may cause damage. The inner sealing connector 22 includes a second sealing element 222 and a bending baffle 223. The second sealing element 222 is made of stainless steel plate bent into a U-shaped structure. The second sealing element 222 is located at the top of pipe 4 and faces the outer sealing connector 21. The two ends of the second sealing element 222 are fixedly connected to the inner side of the outer sealing connector 21. The bottom of the second sealing element 222 is fixedly connected to pipe 4. A second opening is formed between the top of the second sealing element 222 and the outer sealing connector 21. An air guide channel 5 is formed between the first opening and the second opening. The bending baffle 223 is fixedly connected to the top of the second sealing element 222 on the side close to the outer sealing connector 21. The air guide channel 5 enables indoor and outdoor air flow. The air guide channel 5 is set vertically, so rainwater will not enter the room from the air guide channel 5. The bending baffle 223 can prevent rainwater from splashing into the room at the air guide channel 5.
