[0041] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0042] like Figure 1-Figure 5As shown, the marine diesel power comprehensive test room of this embodiment has the laboratory space divided into the bottom layer, the middle layer and the top layer.

The main control room is set up in auxiliary room 6 on the C side of the middle layer.

[0046] On the top floor of the laboratory, an exhaust tower 104 is set in the A-side auxiliary room 4 and the B-side auxiliary room 5, and a hoisting channel 103 is set in the A-span laboratory 1 and the B-span laboratory 3. The hoisting channel 103 meets the hoisting needs of equipment such as diesel engines and gas turbines; an air intake chamber is set in the C-side auxiliary room 6 on the top floor; and a three-story mid-span platform 203 and a side platform 105 are configured.

[0047] A circulating water system 11 is arranged in the bottom space of the laboratory, and the circulating water system 11 comprises:

[0048] The pipe trench 201 is opened at the middle span test room 2, and has a water supply main pipe 111 and a return water main pipe 112.

[0049] A water supply branch pipe 113 and a water return branch pipe 114 are respectively provided in the A-span test room 1 and the B-span test room 3, and the branch pipes of the two-span test rooms are connected to the water supply main pipe 111 and the water return main pipe 112.

[0050] The A-span test room 1 and the B-span test room 3 on the ground floor are respectively equipped with unloading and transportation channels and personnel channels.

[0051] The unloading and transport channel is located on the side of diesel engine group 8 away from gas turbine group 9.

[0052] The personnel passage is located between the test room and the corresponding auxiliary room.

[0053] The C-side auxiliary room 6 on the top floor is equipped with four air intake chambers, including:

[0054] Two air intake chambers with horizontal air intake and upward air intake.

[0055] Two intake chambers with upper intake conditions only.

[0056] The air intake chamber includes an upper air intake duct 16 and a horizontal duct 17 , and at least one of the upper air intake duct 16 and the horizontal duct 17 is connected to the gas turbine 9 .

[0057] The top floor of the middle span test chamber 2 is provided with an exhaust gas treatment device 12 and an exhaust muffler of the diesel engine 8 at the bottom floor.

[0058] The second-layer mid-span platform 202 and the third-layer mid-span platform 203 are located at the middle layer and the top layer of the mid-span laboratory respectively.

[0059] The side platform 105 is located on the top floor of the A-span test chamber 1 and the B-span test chamber 3 , and is located between the gas turbine 9 and the auxiliary room exhaust tower 104 .

[0060] An air intake filter for the bottom-layer diesel engine 8 is arranged on the three-layer middle-span platform 203 .

[0061] The side platform 105 supports the exhaust pipe and the air inlet pipe of the gas turbine 9 in a limited manner.

[0062] The specific structure of the present invention is as follows:

[0063] like Figure 1 FIG. 1 is a plan view of a test room in an embodiment of the present invention. It can be seen from the figure that the entire rectangular shipboard space is divided into opposite sides A and B, and side C located between side A and side B. According to the divided space, the shipboard space is divided into A-span test room 1, middle-span test room 2, B-span test room 3, A-side auxiliary room 4, B-side auxiliary room 5, and C-side auxiliary room 6.

[0064] The layout of the A-span test room 1 and the B-span test room 3 are consistent, and are respectively provided with the A-zone guide rail area 101 and the B-zone guide rail area 301. The hydraulic dynamometer 7 is placed in the A-zone guide rail area 101, and the diesel engine 8, the gas turbine 9, and the power output device 10 are placed in the B-zone guide rail area 301. The foundations of the A-zone guide rail area 101 and the B-zone guide rail area 301 are independent of each other. Under the premise of meeting the equipment installation requirements, this structure can avoid the influence of the hydraulic dynamometer 7 on the vibration measurement of the power output device 10 during operation.

[0065] Two gas turbines 9 and five diesel engines 8 can be placed in the space of the A-span test room 1 and the B-span test room 3. In order to improve the space utilization, the gas turbine 9 is placed horizontally and the diesel engine 8 is placed vertically. The gas turbine 9 is placed on the inner corner of the A-span test room 1 or the B-span test room 3, and the air intake tower and exhaust tower 104 can be set up in the three-story or higher space of the corresponding auxiliary room to meet the air intake and exhaust requirements; the exhaust equipment of the diesel engine 8 is installed on the top of the corresponding side test room. This structure greatly saves space on the basis of the normal operation of each unit.

[0066] like Figure 1 and Figure 2 As shown, in order to meet the circulating water, fuel oil, compressed air and electricity requirements of the gas turbine 9 and the diesel engine 8, the A-side auxiliary room 4 is set as the oil pump room 401, the UPS room 402 and the air compressor station 403; the B-side auxiliary room 5 is set as the power distribution room 501 and the second-floor UPS room 502. A-side trenches 404 are set between the A-span test room 1 and the A-side auxiliary room 4, and in the A-span test room 1; B-side trenches 503 are set between the B-span test room 3 and the B-side auxiliary room 5, and in the B-span test room 3.

[0067] The oil pipes, cables and compressed air pipes led out from the auxiliary room 4 on the A side and the auxiliary room 5 on the B side are introduced into the corresponding cross-test laboratories through the trench 404 on the A side and the trench 503 on the B side to meet the working requirements of equipment such as the gas turbine 9 and the diesel engine 8.

[0068] like Figure 1 As shown, the middle span test room 2 separates the A span test room 1 and the B span test room 3, and the middle span test room 2 is provided with a pipe trench 201, in which a water supply main pipe 111 and a return water main pipe 112 are provided, and a water supply branch pipe 113 and a return water branch pipe 114 are provided in the A span test room 1 and the B span test room 3, respectively. The circulating water flows from the water supply main pipe 111 to the water supply branch pipe 113, and flows back to the return water main pipe 112 through the return water branch pipe 114, forming a circulating water system 11. The circulating water system 11 avoids the cost caused by the intersection of the water supply main pipe 111 and the return water main pipe 112 in the conventional design, and saves space at the same time. It can meet the water demand of all equipment in the two-span test room.

[0069] A cross-laboratory 1 and B cross-laboratory 3 are also provided with an unloading and transportation passage 106 and a personnel passage 107 located around the laboratories.

[0070] like Figure 4 As shown, the top of the middle span test room 2 can be used to place the exhaust gas treatment devices 12 and exhaust silencers of all diesel engines 8 in the test room, and the smoke is discharged from the middle to the outside, which effectively utilizes the space on the top of the auxiliary span and can also play a role in noise reduction.

[0071] like Figure 2The figure shows the second floor plan of the test room. Auxiliary control rooms 102 are arranged on the second floors of the auxiliary room 4 on the A side and the auxiliary room 5 on the B side to independently meet the test requirements of each single gas turbine 9 and diesel engine 8.

[0072] like Figure 1 and Figure 2 As shown, the C side is provided with a C side auxiliary room 6, the first floor of which is a transformer and distribution room, which can meet the power demand of the entire three-story laboratory. The corresponding second floor is the main control room, which meets the joint commissioning and testing requirements of multiple gas turbines 9 and diesel engines 8.

[0073] Combined with reference Figure 3 , Figure 3 The figure in the figure is a plan view of the third floor of the laboratory. It can be seen that hoisting channels 103 are reserved at the opposite sides of the A-span laboratory 1 and the B-span laboratory 3. The hoisting channels 103 are located near the diesel engine 8 and the gas turbine 9. The hoisting equipment in the hoisting channels 103 can be used to arrange the installation and disassembly requirements of any gas turbine 9 or diesel engine 8 in the A-span laboratory 1 and the B-span laboratory 3.

[0074] like Figure 3 As shown, the three-story auxiliary building on the A side is set as the exhaust tower 104 of the gas turbine 9, which meets the exhaust capacity and height requirements of the gas turbine 9. Figure 4 The gas turbine 9 discharges the flue gas into the corresponding exhaust tower 104 through the exhaust duct.

[0075] The third floor of the auxiliary room 6 on the C side is four independent gas turbine 9 air intake chambers, of which two have horizontal air intake and upper air intake conditions, and two have only upper air intake conditions, which can meet the test requirements of the gas turbine 9 under various air intake conditions.

[0076] like Figure 5 As shown, a shutter 14 is provided at the bottom of the air intake chamber, and an air intake silencer and a filter cartridge 15 are provided at the bottom of the air intake chamber. The gas turbine 9 is connected to the air intake chamber through an upper air intake pipe 16 and a horizontal pipe 17. The gas is output after being filtered, thereby meeting the air intake cleanliness and silencer requirements of the gas turbine 9 under both upper and horizontal air intake modes.

[0077] Combined with reference Figure 2 and Figure 3The test room is equipped with a two-story mid-span platform 202 with a height of 4.5 meters, which is convenient for personnel to enter the test room from the muffler door of the control room to observe and inspect the operating status of the unit. The test room is equipped with a three-story mid-span platform 203 with a height of 8.5 meters for arranging the intake filter of the diesel engine 8. The side platform 105 located near the exhaust tower 104 of the A-span test room 1 and the B-span test room 3 is used to bear and fix the exhaust pipe and intake pipe of the gas turbine 9. The setting of these platforms greatly improves the space utilization rate, and at the same time allows personnel to enter the upper intake chamber from the three-story mid-span platform 203 through the inspection door to check the status of the intake chamber before the test.

[0078] The above description is an explanation of the present invention, not a limitation of the present invention. The scope of the present invention is defined in the claims. Any form of modification may be made within the scope of protection of the present invention.
