[0036] The purpose of this utility model is to provide a turbocharger bracket and a marine diesel engine, which reduces the difficulty of arranging the diesel engine's external intake pipe 400 and the turbocharger. The diesel engine has a higher degree of integration and is more compact and aesthetically pleasing. It can effectively shorten the size of the diesel engine and facilitate its arrangement in the ship's cabin. At the same time, it effectively solves the problem of needing to provide support and lubricating oil inlet and outlet, as well as the connection of the intake pipe 400, at the same location of the turbocharger itself.

[0037] Please see Figures 1 to 4 To achieve the above objectives, this utility model provides a turbocharger bracket for a marine diesel engine, used to support a turbocharger located on one side of the diesel engine. The turbocharger bracket includes a first support plate 200, a support body 300, and an intake pipe 400.

[0038] The first support plate 200 is fixed relative to the diesel engine. Specifically, the first support plate 200 is fixedly connected to the mounting plate 100, and the mounting plate 100 has a connection hole 110. A connector is passed through the connection hole 110 and fixed to the body of the diesel engine, so that the mounting plate 100 and the diesel engine are connected, thereby fixing the first support plate 200 relative to the diesel engine. The connector can be bolts or the like, as long as the above purpose can be achieved.

[0039] The support body 300 is connected to the first support plate 200. The support body 300 is used to support the intermediate body connected to the turbocharger. The support body 300 is provided with a first oil inlet and return channel, which is connected to the second oil inlet and return channel of the intermediate body. The intake pipe 400 is provided on the first support plate 200, and one end of the intake pipe 400 is connected to the compressor end of the turbocharger.

[0040] The first support plate 200 is fixed relative to the diesel engine. The support body 300 is integrated into the first support plate 200 and is connected to the intermediate body of the turbocharger through the support body 300 to support the turbocharger. The support body 300 is provided with a first oil inlet and return channel that is connected to the second oil inlet and return channel on the intermediate body to realize the oil inlet and return. The intake pipe 400 is integrated into the first support plate 200. This arrangement reduces the difficulty of arranging the external intake pipe 400 of the diesel engine and the turbocharger. The diesel engine has a higher degree of integration and is more compact and beautiful. It can effectively shorten the size of the diesel engine and facilitate the arrangement of the diesel engine in the ship's cabin. At the same time, it effectively solves the problem that the turbocharger itself needs to provide support and oil inlet and return channels as well as the connection of the intake pipe 400 in the same position.

[0041] In this embodiment, the support body 300 is a protruding structure protruding from one side of the first support plate 200. The end of the support body 300 away from the first support plate 200 is provided with a first oil inlet channel 310 and a first oil return channel 320 to form a first oil inlet and return channel. The first oil return channel 320 includes a connecting part that extends to the other side of the support plate to form a protrusion. The connecting part facilitates the connection of other pipelines with the outlet of the first oil return channel 320. A side hole 311 communicating with the first oil inlet channel 310 is provided on one side wall of the support body 300 to allow fluid to enter the first oil inlet channel 310 along the side hole 311. Correspondingly, the second oil inlet and return channel includes a second oil inlet channel and a second oil return channel. The second oil inlet channel is connected to the first oil inlet channel 310, and the second oil return channel is connected to the first oil return channel 320.

[0042] The support body 300 is provided with a first annular groove 330 and a second annular groove 340 at one end away from the first support plate 200. The first annular groove 330 is located on the outer periphery of the first oil inlet channel 310, and the second annular groove 340 is located on the outer periphery of the first oil return channel 320. The sealing ring is installed in the first annular groove 330 and the second annular groove 340 to seal the connection between the first oil inlet and return channel and the second oil inlet and return channel to prevent lubricating oil leakage.

[0043] In this embodiment, the turbocharger bracket further includes a second support plate 500, a third support plate 600, and a fourth support plate 700. The second support plate 500 is connected to the side of the first support plate 200 away from the support body 300. The third support plate 600 and the second support plate 500 are disposed on the same side relative to the first support plate 200, and the third support plate 600 is connected to the second support plate 500 and the first support plate 200. The fourth support plate 700 and the third support plate 600 are disposed on the same side relative to the first support plate 200, and the fourth support plate 700 is connected to the end of the third support plate 600 away from the second support plate 500. The fourth support plate 700 and the second support plate 500 are parallel to each other.

[0044] It should be noted that the first support plate 200 is vertically connected to the mounting plate 100. Typically, the mounting plate 100 is vertically positioned and the first support plate 200 is horizontally positioned. To ensure the fixed connection between the first support plate 200 and the mounting plate 100, and to ensure that the first support plate 200 has sufficient support strength, a second support plate 500, a third support plate 600, and a fourth support plate 700 are added on one side of the first support plate 200 (e.g., the bottom of the first support plate 200) to support the first support plate 200. Specifically, the second support plate 500 and the fourth support plate 700 are connected to the mounting plate 100 through parallel structures, and the tops of the second support plate 500 and the fourth support plate 700 are connected to the first support plate 200. The third support plate 600 is connected to the middle of the second support plate 500 and the fourth support plate 700 to form a support assembly with a horizontal cross-section of "H". The top of the third support plate 600 is also connected to the first support plate 200 to improve the support effect on the first support plate 200.

[0045] The first support plate 200 can be a plate structure. The tops of the second support plate 500, the third support plate 600, and the fourth support plate 700 are set at the same height to keep the first support plate 200 horizontal. The connection between the first support plate 200, the second support plate 500, the third support plate 600, and the fourth support plate 700 can be welded. The specific dimensions of the first support plate 200, the second support plate 500, the third support plate 600, and the fourth support plate 700 can be adjusted according to the installation space of the bracket booster to achieve the above objectives.

[0046] In some embodiments, the first support plate 200 is provided with a first through hole, the second support plate 500 is provided with a second through hole, and the intake pipe 400 includes a first end passing through the first through hole and a second end passing through the second through hole. The first end protrudes from the first support plate 200 to form a first flange 410, and the second end protrudes from the second support plate 500 to form a second flange 420. The first flange 410 can be connected to the compressor end of the turbocharger through an expansion joint, and the second flange 420 can be connected to the air cooler through a connecting pipe to realize the flow of gas between the compressor end of the turbocharger and the air cooler.

[0047] It is understandable that the above-mentioned support assembly with an "H"-shaped horizontal cross section can form two slots. To facilitate the rational use of space, the main body of the intake pipe 400 can be placed in the slot of the mounting plate 100 in the two slots to protect the intake pipe 400, while improving space utilization efficiency and reducing the overall volume of the turbocharger bracket. The connection part of the first oil return channel 320 is placed in another slot, which has two openings to facilitate the docking of other pipelines and connections, thereby improving work efficiency. That is, the third support plate 600 connected between the second support plate 500 and the fourth support plate 700 is used to separate the connection part and the intake pipe 400, and to make full use of space to reduce the overall volume of the turbocharger bracket.

[0048] In some embodiments, the bottom of the support body 300 is provided with a first reinforcing plate 350 connected to the first support plate 200. The first reinforcing plate 350 has a triangular structure, and the two sides of the triangular structure are respectively attached to the support body 300 and the first support plate 200. The support body 300 can be set perpendicular to the first support plate 200, that is, the side surface of the support body 300 is perpendicular to the top surface of the first support plate 200. The first reinforcing plate 350 is set as a right-angled triangular plate. By attaching the two right-angled sides of the right-angled triangular plate to the side surface of the support body 300 and the top surface of the first support plate 200, the stability between the support body 300 and the first support plate 200 is improved.

[0049] Similarly, a second reinforcing plate 510 can be provided on the side of the second support plate 500 away from the third support plate 600. The second reinforcing plate 510 is connected to both the second support plate 500 and the first support plate 200 to improve the stability between the second support plate 500 and the first support plate 200. A third reinforcing plate 710 can be provided on the side of the fourth support plate 700 away from the third support plate 600. The third reinforcing plate 710 is connected to both the fourth support plate 700 and the first support plate 200 to improve the stability between the fourth support plate 700 and the first support plate 200. The second reinforcing plate 510 and the third reinforcing plate 710 can also be right-angled triangular plates.

[0050] It should be noted that the turbocharger bracket is an integral structure, which can be integrally injection molded, integrally cast, or the components can be welded into a whole according to the preset position. This setting can effectively shorten the size of the diesel engine and make the diesel engine layout more compact. At the same time, the first support plate 200 is provided with turbine rear pipe bracket mounting hole 220 and monitoring device bracket mounting hole 210, which has a higher degree of integration.

[0051] In addition, this application also provides a marine diesel engine equipped with a turbocharger bracket of any of the above-mentioned marine diesel engines, which also has the beneficial effects of the turbocharger bracket of the above-mentioned marine diesel engines, and will not be described in detail here.
