[0032] The specific embodiments of this utility model are described below with reference to the accompanying drawings.
[0033] like Figures 1-5 As shown, the marine diesel-powered integrated test laboratory of this embodiment divides the ship's space into three levels. Each level is further divided into side A, side B, and side C. Sides A and B are arranged opposite each other, and side C connects side A and side B.
[0034] The bottom layer has two sets of independently installed diesel engines 8, gas turbines 9, power output devices 10, and hydraulic dynamometers 7, symmetrically arranged on sides A and B.
[0035] The ground and middle floors are equipped with auxiliary rooms including oil pump room 401, UPS room 402, air compressor station 403, power distribution room 501, auxiliary control room 102, and transformer substation.
[0036] The third-floor auxiliary building is equipped with an exhaust tower 104 and an air intake chamber.
[0037] Support platforms are provided on both the second and third floors.
[0038] A central span test chamber 2 is located in the middle of the first-floor space, and span A test chamber 1 and span B test chamber 3 are located on both sides. A pipe trench 201 is set up in the central span test chamber 2. A main water supply pipe 111 and a main return water pipe 112 are set up in the pipe trench 201. A branch water supply pipes 113 and return water branch pipes 114 are set up in span A test chamber 1 and span B test chamber 3. The main water supply pipe 111, the main return water pipe 112, the branch water supply pipes 113 and the branch water return pipes 114 constitute a circulating water system 11.
[0039] The exhaust gas treatment device for diesel engine 8 and the exhaust muffler for diesel engine 8 are placed on the top of the intermediate cross-chamber 2.
[0040] The guide rail foundations of the A-span test chamber 1 and B-span test chamber 3 on the first floor are independent of each other.
[0041] In the A-span test chamber 1 and B-span test chamber 3 on the first floor, the gas turbine 9 is placed parallel to the middle span test chamber 2, and the diesel engine 8 is placed perpendicular to the middle span test chamber 2.
[0042] The three-story A-span laboratory and B-span test room 3 are each equipped with a hoisting channel 103.
[0043] The air intake chambers of the three-story C-side auxiliary room 6 include: an air intake chamber with both horizontal and upward air intake conditions, and an air intake chamber with only upward air intake conditions.
[0044] The top of the air intake chamber is provided with a louver 14 and is connected to an air intake muffler. The air intake muffler is connected to a filter cartridge 15 in the horizontal plane. The filter cartridge 15 is connected to at least one of the upper air intake pipe 16 and the horizontal pipe 17.
[0045] Platforms are located on the second and third floors of the laboratory.
[0046] Both cross-laboratory 1 (A) and cross-laboratory 3 (B) are equipped with unloading and transportation channels and personnel channels.
[0047] The specific structure of this utility model is as follows:
[0048] like Figure 1 The figure shows a floor plan of the laboratory in one embodiment of this utility model. The rectangular space on the ship is divided into two opposing sides: A and B, and a side C located between A and B. Based on these divisions, the space on the ship is further divided into A-span laboratory 1, intermediate-span laboratory 2, B-span laboratory 3, A-side auxiliary room 4, B-side auxiliary room 5, and C-side auxiliary room 6.
[0049] The layout of spanned test chamber 1 and spanned test chamber 3 is identical, with guide rail area 101 in section A and guide rail area 301 in section B, respectively. A hydraulic dynamometer 7 is placed in guide rail area 101, while a diesel engine 8, a gas turbine 9, and a power output device 10 are placed in guide rail area 301. The foundations of guide rail areas 101 and 301 are independent of each other. This structure, while meeting equipment installation requirements, avoids the influence of the hydraulic dynamometer 7 on the vibration measurement of the power output device 10 during operation.
[0050] Both span 1 (A-span) and span 3 (B-span) can accommodate two gas turbines 9 and five diesel engines 8. To improve space utilization, the gas turbines 9 are placed horizontally, and the diesel engines 8 are placed vertically. Placing the gas turbines 9 in the inner corner of their respective span 1 (A-span) or span 3 (B-span) allows for the use of the upper three floors of the corresponding auxiliary building to install intake and exhaust towers 104, thus meeting intake and exhaust requirements. The exhaust equipment for the diesel engines 8 is installed on the top of the corresponding side chamber. This structure significantly saves space while ensuring the normal operation of each unit.
[0051] like Figure 1 and Figure 2 As shown, to meet the circulating water, fuel oil, compressed air, and electricity requirements of the gas turbine 9 and diesel engine 8, the auxiliary building 4 on side A is designated as the oil pump room 401, UPS room 402, and air compressor station 403; the auxiliary building 5 on side B is designated as the power distribution room 501 and the second-floor UPS room 502. A-side trenches 404 are installed between test chamber 1 and auxiliary building 4 on side A, and within test chamber 1 on side A; B-side trenches 503 are installed between test chamber 3 and auxiliary building 5 on side B, and within test chamber 3 on side B.
[0052] Oil pipes, cables, and compressed air pipes leading from auxiliary rooms 4 on side A and 5 on side B are introduced into the corresponding cross-test chambers through trench 404 on side A and trench 503 on side B, to meet the working requirements of equipment such as gas turbine 9 and diesel engine 8.
[0053] like Figure 1 As shown, intermediate span test chamber 2 separates span test chamber 1 (A span) and span test chamber 3 (B span). Intermediate span test chamber 2 is equipped with a pipe trench 201, within which a main water supply pipe 111 and a main water return pipe 112 are installed. Span test chamber 1 (A span) and span test chamber 3 (B span) are respectively equipped with water supply branch pipes 113 and water return branch pipes 114. These water supply branch pipes 113 and water return branch pipes 114 return to the main water supply pipe 111 and water return pipe 112, forming a circulating water system 11. This circulating water system 11 avoids the costs caused by the intersection of the main water supply pipe 111 and the main water inlet pipe in conventional designs, while also saving space. It can meet the water needs of all equipment in both span test chambers.
[0054] A-section laboratory 1 and B-section laboratory 3 are also equipped with unloading and transportation channels 106 and personnel channels 107 located around the laboratories.
[0055] like Figure 4 As shown, the top of the middle span test chamber 2 can accommodate the exhaust gas treatment devices 12 and exhaust mufflers of all diesel engines 8 in the test chamber, which discharge the exhaust gas from the middle to the outside. This effectively utilizes the space at the top of the auxiliary span and also reduces noise.
[0056] like Figure 2 The diagram shows the second floor plan of the laboratory. On the second floor of auxiliary rooms 4 on side A and 5 on side B, auxiliary control rooms 102 are set up to independently meet the testing needs of each individual gas turbine 9 and diesel engine 8.
[0057] like Figure 1 and Figure 2 As shown, auxiliary room 6 is located on side C. The first floor of auxiliary room 6 is a power distribution room, which can meet the power needs of the entire three-story test laboratory. The corresponding second floor is the main control room, which meets the needs of joint commissioning and testing of multiple gas turbines 9 and diesel engines 8.
[0058] Reference Figure 3 , Figure 3 The middle section is a floor plan of the third floor of the laboratory. It can be seen that hoisting channels 103 are reserved on opposite sides of laboratory A 1 and laboratory B 3. Hoisting channels 103 are located near diesel engine 8 and gas turbine 9. The hoisting equipment in hoisting channels 103 can accommodate the installation and disassembly of any gas turbine 9 or diesel engine 8 in laboratory A 1 or laboratory B 3.
[0059] like Figure 3 As shown, the three-story auxiliary building on side A is configured as the exhaust tower 104 for gas turbine 9, meeting the exhaust capacity and height requirements of gas turbine 9, in conjunction with reference... Figure 4 The gas turbine 9 discharges the flue gas into the corresponding exhaust tower 104 through the exhaust pipe.
[0060] The three floors of the auxiliary building 6 on side C contain four independent gas turbine 9 intake chambers. Two of these chambers have both horizontal and vertical intake conditions, while the other two only have vertical intake conditions. This combination can meet the testing requirements of the gas turbine 9 under various intake conditions.
[0061] like Figure 5 As shown, a louver 14 is provided at the bottom of the intake chamber, and an intake silencer and filter cartridge 15 are provided below the intake chamber. The gas turbine 9 is connected to the intake chamber through an upper intake pipe 16 and a horizontal pipe 17. The gas is output after filtration, which meets the requirements of intake cleanliness and noise reduction of the gas turbine 9 under both upper and horizontal intake modes.
[0062] Reference Figure 2 and Figure 3 The test chamber is equipped with a second-floor mid-span platform 202 at an elevation of 4.5 meters, facilitating personnel access from the control room's silenced door to observe and inspect the unit's operating status. A third-floor mid-span platform 203 at an elevation of 8.5 meters is installed to house the intake filter of the diesel engine 8. Side platforms 105, located near the exhaust tower 104 in test chambers A and B (span 1 and B), support and secure the exhaust and intake pipes of the gas turbine 9. These platforms significantly improve space utilization and allow personnel to access the upper intake chamber from the third-floor mid-span platform 203 through the maintenance door to inspect its condition before testing.
[0063] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
