Description

Technical Field

[0001] This invention relates to the field of diesel engine power station technology, and more specifically to a power station exhaust connection pipeline for a top-mounted muffler. Background Technology

[0002] Currently, with the increasing size requirements of military power stations, most power stations have a compact internal layout, and some equipment, such as silencers, are usually externally mounted to meet the size requirements. The existing structure mainly consists of flanges on both the inner and outer walls of the power station compartment. One end of the exhaust pipe is connected to the diesel engine, and the other end is connected to the flange on the inner side of the compartment / wall. The external silencer's inlet pipe flange is connected to the flange on the outer side of the compartment wall.

[0003] Due to the compact structure of the prefabricated power station, the space for tightening bolts connecting the exhaust pipe to the flanges on the inner wall of the prefabricated unit is very limited, making flange installation inconvenient. Since the exhaust pipe is fixed to the prefabricated unit via flanges at both ends, subsequent maintenance requiring the removal of the top cover necessitates the removal of the internal fixing flange bolts, significantly increasing maintenance difficulty. Furthermore, the direct connection between the silencer and the flanges on the outer wall of the prefabricated unit makes it impossible to guarantee a tight seal, allowing water to easily seep into the power station during heavy rain. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a power plant exhaust connection pipeline for a top-mounted silencer. While meeting the power plant exhaust requirements, it ensures the sealing of the power plant exhaust pipeline and improves the convenience of power plant maintenance.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A power station exhaust connection pipeline for a top-mounted muffler includes a power station housing (1), an exhaust pipe (2), a muffler (3), an inlet pipe (4), a semi-circular transition flange (5), a mounting flange (6), a mounting block (7), a first sealing gasket (8), a second sealing gasket (9), and bolts (11). One end of the exhaust pipe is connected to the exhaust port of a diesel engine, and the other end is connected to the inlet pipe. The downstream end of the inlet pipe is connected to a muffler. The characteristic feature is that, along the axial direction of the exhaust pipe, the flange portion (42) of the inlet pipe, the first sealing gasket, the semi-circular transition flange, the second sealing gasket, the mounting flange, the power station housing, and the mounting block are connected in sequence. The bolts pass through the corresponding bolt mounting holes on the flange portion of the inlet pipe, the first sealing gasket, the semi-circular transition flange, the second sealing gasket, the mounting flange, and the power station housing in sequence and are then threadedly connected to the mounting block.

[0006] Furthermore, the exhaust pipe (2) includes an exhaust pipe body (21), a rectangular flange (22), and a circular flange (23). The rectangular flange and the circular flange are respectively connected to the two ends of the exhaust pipe body. The rectangular flange is connected to the exhaust port of the diesel engine by bolts. There are two semi-circular transition flanges. A stop (51) is provided on the inner circumference of the semi-circular transition flange. The circular flange is embedded and placed in the stop.

[0007] Furthermore, the smoke inlet pipe (4) includes a smoke inlet pipe body (41), a flange (42), and a cover (43). The flange is connected to the lower end of the smoke inlet pipe body. The outer periphery of the flange is turned down to provide an annular cover. The annular cover covers the outer periphery of the semi-circular transition flange, the first sealing gasket, the second sealing gasket, and at least a part of the mounting flange.

[0008] Furthermore, the flange, semi-circular transition flange, mounting flange, and power station housing are all provided with multiple bolt mounting holes distributed circumferentially. The mounting blocks are provided with internal threaded holes. Multiple mounting blocks are distributed circumferentially and are fixedly connected to the inner side of the power station housing. After installation, high-temperature adhesive is applied between the bottom of the mounting flange and the power station housing for sealing.

[0009] Furthermore, the device also includes a water collection component (10), which includes a pipe body (101), a conical water collection cover (102), a water collection ring groove (103), and a connecting hole (104). The outer circumferential surface of the pipe body is connected to the inner circumferential surface of the mounting flange. The upper end face of the pipe body abuts against the second sealing gasket. The mounting flange is installed on the upper surface of the power station housing. The mounting block is located on the outer circumferential side of the pipe body. A conical water collection cover is provided on the inner circumferential surface of the lower end of the pipe body. A water collection cavity is formed between the conical water collection cover and the pipe body. A water collection ring groove is provided on the outer circumferential surface of the lower end of the pipe body. A water collection ring groove is formed between the water collection ring groove and the pipe body. A connecting hole is provided on the pipe body. The water collection cavity and the water collection cavity are connected through the connecting hole.

[0010] Furthermore, the first and second sealing gaskets are asbestos gaskets, and the exhaust pipe is an exhaust corrugated pipe.

[0011] Furthermore, when the power station needs to remove the top cover for maintenance, the silencer can be removed from the top and the two semi-circular transition flanges (5) can be removed to open the entire top cover, thus avoiding operation in the crowded space inside the power station and improving the convenience of power station maintenance.

[0012] This invention provides a power station exhaust connection pipe for a top-mounted silencer, which meets the power station's exhaust requirements while ensuring the pipe's airtightness and improving the ease of maintenance. The invention's design, through the inclusion of a water-collecting component, prevents rainwater from seeping into the power station housing due to aging of the sealing gasket or during heavy rain, thus enabling the collection of any rainwater that may infiltrate.
