Description

Technical Field

[0001] The utility model relates to the technical field of diesel generator sets, in particular to a typhoon-resistant container-type diesel generator set for offshore wind power. Background Art

[0002] With the continuous development of large-capacity offshore wind turbines, in order to meet the needs of wind turbines to resist typhoons, offshore wind turbines have begun to be equipped with diesel generator sets as backup power sources during typhoons. Considering the size of the wind turbine tower and the constraints of the diesel generator set's air intake and smoke exhaust, the diesel generator set is generally installed on the platform outside the wind turbine tower, which is equivalent to being completely exposed to the marine environment. During the typhoon, the air is mixed with high salt fog and high water vapor, which puts forward strict requirements on the anti-salt fog and anti-corrosion of the diesel generator set. The exterior must meet the CX anti-corrosion grade and HV durability, and the interior must meet the C4 anti-corrosion grade and H durability. If effective protective measures are not taken, it will cause serious damage to the diesel generator. Considering the severe typhoon weather, the diesel generator set must have sufficient strength to withstand the damage caused by typhoons and waves. In addition, the atmospheric pressure in the typhoon area is lower than the normal atmospheric pressure, and it is possible to form a negative pressure between the engine room and the engine room, so that the diesel generator set cannot enter enough air when it starts and cannot start. In addition, as part of the delivery of wind turbines, the life cycle of diesel generator sets must be consistent with that of offshore wind turbines. In order to meet the offshore operating environment, diesel generator sets need to meet the requirements of high strength, high corrosion resistance, and high reliability. However, existing diesel generator sets cannot be directly exposed to the high salt fog and high humidity environment at sea, nor can they meet the operating requirements and strength requirements during super typhoons. In addition to the above shortcomings, existing diesel generator sets are also prone to oil leakage, and the leaked diesel will leak into the ocean, polluting the marine environment.

[0003] Therefore, it is necessary to provide a containerized diesel generator set suitable for offshore wind turbines to resist typhoons to solve the above technical problems. Summary of the invention

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a typhoon-resistant containerized diesel generator set for offshore wind power, which can meet the requirements of corrosion resistance, not only can solve the problem of air intake and exhaust in the marine environment, but also can solve the problem of typhoon resistance, avoid oil leakage into the ocean, and protect the marine environment.

[0005] In order to achieve the above purpose, the technical solution provided by the utility model is:

[0006] A typhoon-resistant containerized diesel generator set for offshore wind power generation, comprising a diesel generator, an oil storage tank, a container body and a control cabinet;

[0007] The two ends of the container body are respectively provided with an air inlet and an air outlet;

[0008] An air inlet filtration system is provided at the air inlet;

[0009] An exhaust and heat dissipation system is provided at the exhaust port;

[0010] The surrounding surface of the container body is a corrugated structure;

[0011] The diesel generator, oil storage tank and control cabinet are all installed inside the container body;

[0012] The control cabinet is connected with the air inlet filtration system and the exhaust cooling system, and is used for controlling the air inlet filtration system and the exhaust cooling system.

[0013] In this technical solution, an air inlet filtration system and an exhaust cooling system are respectively provided at the air inlet and exhaust outlet of the container body. Both the air inlet filtration system and the exhaust cooling system are controlled by a control cabinet, which can solve the problem of air intake and exhaust in a marine environment.

[0014] The diesel generator, fuel storage tank and control cabinet are all installed inside the container body, and the surrounding surface of the container body is a corrugated structure, which can solve the problem of typhoon resistance.

[0015] Further, the air inlet filtration system includes an air inlet hood, a salt spray filter, and an air inlet electric shutter;

[0016] The air inlet hood is installed at one end of the container body where the air inlet is opened, and is placed outside the air inlet;

[0017] The salt spray filter is arranged in the air inlet hood and is located outside the air inlet;

[0018] The air inlet electric shutter is arranged on the inner side of the air inlet and is electrically connected to the control cabinet.

[0019] In this technical solution, the opening and closing of the air inlet electric shutters can be controlled by the control cabinet according to actual conditions, so as to avoid the diesel generator from directly contacting the ocean air for a long time, thereby increasing the service life of the diesel generator.

[0020] In addition, even if the air inlet electric shutters are in the open state, the ocean air entering the container can be filtered through the salt spray filter to meet the anti-corrosion requirements.

[0021] In addition, the air inlet hood is placed on the periphery of the air inlet to prevent the ocean air from directly impacting the salt spray filter and the air inlet electric shutter.

[0022] Furthermore, the exhaust and heat dissipation system includes an exhaust hood, a radiator, and an exhaust electric shutter;

[0023] The exhaust hood is installed at one end of the container body where the exhaust port is opened, and is placed outside the exhaust port;

[0024] The exhaust electric shutter is installed on the inner side of the exhaust port;

[0025] The radiator is arranged on a side of the diesel generator away from the air inlet, and an air guide cover is arranged between the radiator and the exhaust electric shutter;

[0026] The exhaust electric shutter is electrically connected to the control cabinet.

[0027] In the present technical solution, the opening and closing of the exhaust electric shutters can also be controlled by the control cabinet according to actual conditions, so as to avoid the diesel generator from directly contacting the ocean air for a long time and prolong the service life.

[0028] The radiator discharges the heat generated by the diesel generator from the exhaust port of the container body, ensuring that the temperature inside the container body is maintained at a certain level so that the diesel generator will not shut down due to high temperature.

[0029] The exhaust hood is placed on the periphery of the exhaust port to prevent the ocean air from directly impacting the exhaust electric shutters.

[0030] Furthermore, the opening of the air inlet hood communicating with the outside world and the opening of the air exhaust hood communicating with the outside world are both facing downward, which can not only meet the conditions for ocean air to enter the container body, but also prevent ocean air from directly impacting the air inlet electric shutters and the exhaust electric shutters.

[0031] Furthermore, the outer surfaces of the air inlet hood and the air exhaust hood are both corrugated structures, so that the overall strength of the containerized diesel generator set is enhanced and the reliability of typhoon resistance is improved.

[0032] Furthermore, a first oil storage tank is provided around the oil storage tank, and an oil level sensor is provided in the first oil storage tank;

[0033] The oil level sensor is electrically connected to the control cabinet;

[0034] The control cabinet is provided with an alarm.

[0035] In this technical solution, if the oil storage tank leaks, the leaked diesel will first enter the first oil storage tank to avoid oil leakage into the ocean. Moreover, when the oil level sensor detects that there is diesel in the first oil storage tank, the alarm will sound to give a warning.

[0036] Furthermore, a fire protection system is provided in the container;

[0037] The fire protection system includes smoke detectors, temperature detectors, fire extinguishing devices, and fire alarm control boxes;

[0038] The fire extinguishing device is arranged on the top of the container body;

[0039] The smoke detector, temperature detector and fire extinguishing device are all electrically connected to the fire alarm control box;

[0040] The fire alarm control box is electrically connected to the control cabinet.

[0041] In this technical solution, smoke detectors and temperature detectors are used to detect whether a fire occurs inside the container. If a fire occurs, the fire alarm control box controls the fire extinguishing device to extinguish the fire, and the control cabinet controls the closing of the air inlet electric shutters and the exhaust electric shutters.

[0042] Furthermore, the container body is provided with a smoke exhaust pipe, and the thick smoke generated by the fire will be discharged from the smoke exhaust pipe to prevent the thick smoke from accumulating in the container body and affecting the subsequent fire fighting of the staff.

[0043] Furthermore, a second oil storage tank is provided at the bottom around the container body. Compared with the first oil storage tank, the second oil storage tank can prevent oil leakage into the ocean due to oil leakage of the diesel generator.

[0044] Furthermore, the container body also includes a dehumidifier, which is electrically connected to the control machine to ensure that the humidity in the container body can be maintained at a certain level, thereby increasing the operating life of the equipment.

[0048] 2. According to the actual situation, the opening and closing of the air inlet electric shutters can be controlled by the control cabinet to avoid the diesel generator from being directly exposed to the ocean air for a long time, thereby increasing the service life of the diesel generator.

[0049] In addition, even if the air inlet electric shutters are in the open state, the ocean air entering the container can be filtered through the salt spray filter to meet the anti-corrosion requirements.

[0050] In addition, the air inlet hood is placed on the periphery of the air inlet to prevent the ocean air from directly impacting the salt spray filter and the air inlet electric shutter.

DETAILED DESCRIPTION

[0060] The utility model is further described below in conjunction with specific implementation methods:

[0061] like Figures 1 to 3 As shown, a container-type diesel generator set for offshore wind power and typhoon resistance described in this embodiment includes a diesel generator 1, an oil storage tank 2, a container body 3 and a control cabinet 4.

[0062] An air inlet 5 and an air outlet 6 are respectively provided at both ends of the container body 3; an air inlet filtration system is provided at the air inlet 5; an exhaust cooling system is provided at the exhaust vent 6; the surrounding surface of the container body 3 is a corrugated structure; the diesel generator 1, the oil storage tank 2, and the control cabinet 4 are all installed inside the container body 3; the control cabinet 4 is connected to the air inlet filtration system and the exhaust cooling system, and is used to control the air inlet filtration system and the exhaust cooling system.

[0063] The air inlet filtration system includes an air inlet hood 7, a salt spray filter 8, and an air inlet electric shutter 9; the air inlet hood 7 is installed at one end of the container body 3 where the air inlet 5 is opened, and is placed on the periphery of the air inlet 5; the salt spray filter 8 is arranged in the air inlet hood 7 and is located on the outside of the air inlet 5; the air inlet electric shutter 9 is arranged on the inside of the air inlet 5 and is electrically connected to the control cabinet 4.

[0064] The exhaust and heat dissipation system includes an exhaust hood 10, a radiator 11, and an exhaust electric shutter 12; the exhaust hood 10 is installed at one end of the container body 3 where the exhaust port 6 is opened, and is placed on the periphery of the exhaust port 6; the exhaust electric shutter 12 is installed on the inner side of the exhaust port 6; the radiator 11 is arranged on the side of the diesel generator 1 away from the air inlet 5, and an air guide hood is provided between the radiator 11 and the exhaust electric shutter 12; the exhaust electric shutter 12 is electrically connected to the control cabinet 4.

[0065] In the above description, the opening of the air inlet hood 7 communicating with the outside world and the opening of the air exhaust hood 10 communicating with the outside world are both facing downward, and the outer surfaces of the air inlet hood 7 and the air exhaust hood 10 are both corrugated structures.

[0066] A first oil storage tank 13 is provided around the oil storage tank 2, and an oil level sensor 14 is provided in the first oil storage tank 13; the oil level sensor 14 is electrically connected to the control cabinet 4; and an alarm is provided in the control cabinet 4. A second oil storage tank 20 is provided at the bottom around the container.

[0067] A fire protection system, a dehumidifier 21 and a smoke exhaust pipe 19 leading to the outside of the container body 3 are installed in the container body 3; the fire protection system includes a smoke detector 15, a temperature detector 16, a fire extinguishing device 17 (specifically a heptafluoropropane fire extinguishing device 17), and a fire alarm control box 18; the fire extinguishing device 17 is arranged at the top of the container body 3; the smoke detector 15, the temperature detector 16 and the fire extinguishing device 17 are all electrically connected to the fire alarm control box 18; the fire alarm control box 18 and the dehumidifier 21 are both electrically connected to the control cabinet 4.

[0068] In this embodiment,

[0069] When the diesel generator 1 is started, the control cabinet 4 first controls the air inlet electric shutter 9 and the exhaust electric shutter 12 to open, and at the same time the salt spray filter 8 is also opened, and the radiator 11 is started; then, the control cabinet 4 will start the diesel generator 1 to work. After the diesel generator 1 is working, the external ocean air enters from the downward opening of the air inlet hood 7, and the water vapor and salt spray in the air are filtered out by the salt spray filter 8, so that dry and clean air enters the container body 3 to ensure the intake volume required for the normal combustion and heat dissipation of the diesel generator 1. Then, the radiator 11 discharges the heat generated by the diesel generator 1 from its exhaust port 6 to ensure that the temperature in the container body 3 is maintained at a certain level so that the unit will not shut down due to high temperature. After the heat comes out of the exhaust port 6 of the radiator 11, it passes through the electric shutter of the exhaust port 6 and enters the exhaust hood 10, and is discharged from the downward opening of the exhaust hood 10. In the entire air intake and exhaust system, cold air enters from the downward opening of the air inlet hood 7, and hot air is discharged from the downward opening of the exhaust hood 10, which increases the air intake and exhaust channels, effectively reduces the impact of typhoons on the air intake, and makes the air intake and exhaust smoother in typhoon weather, ensuring that the air intake volume can meet the normal operation and cooling needs of the unit.

[0070] The fire protection system works as follows:

[0071] If a fire occurs inside the container body 3 for some reason, the smoke detector 15 senses thick smoke, and the temperature detector 16 senses that the temperature inside the container body 3 exceeds the set value, and the fire alarm control box 18 will send a fire alarm signal to the control cabinet 4. If the diesel generator 1 is running at this time, the control cabinet 4 will issue an emergency stop command, and the diesel generator 1, the air inlet electric shutter 9 and the exhaust electric shutter 12 will be closed. At the same time, the fire alarm control box 18 sends a fire extinguishing signal to the suspended HFC-227ea fire extinguishing device 17, and HFC-227ea is sprayed out to extinguish the fire; if the diesel generator 1 is in standby mode, the fire alarm control box 18 directly sends a fire extinguishing signal to the HFC-227ea fire extinguishing device 17 to extinguish the fire.

[0072] In this embodiment,

[0073] An air inlet filtration system and an exhaust cooling system are respectively added to the air inlet 5 and the air outlet 6 of the container body 3, and the air inlet filtration system and the exhaust cooling system are both controlled by the control cabinet 4, which can solve the problem of air intake and exhaust in the marine environment. The diesel generator 1, the oil storage tank 2, and the control cabinet 4 are all installed inside the container body 3, and the surrounding surface of the container body 3 is a corrugated structure, which can solve the problem of typhoon resistance.

[0074] According to the actual situation, the opening and closing of the air inlet electric shutter 9 can be controlled by the control cabinet 4 to prevent the diesel generator 1 from directly contacting the ocean air for a long time, thereby improving the service life of the diesel generator 1. In addition, even if the air inlet electric shutter 9 is in the open state, the ocean air entering the container body 3 can be filtered by the salt spray filter 8 to meet the anti-corrosion requirements. In addition, the air inlet hood 7 is placed on the periphery of the air inlet 5 to prevent the ocean air from directly impacting the salt spray filter 8 and the air inlet electric shutter 9.

[0075] Similarly, the opening and closing of the exhaust electric shutter 12 can be controlled by the control cabinet 4 according to actual conditions, so as to prevent the diesel generator 1 from being directly in contact with the ocean air for a long time, thereby increasing the service life. The radiator 11 discharges the heat generated by the diesel generator 1 from the exhaust port 6 of the container body 3, ensuring that the temperature inside the container body 3 is maintained at a certain level, so that the diesel generator 1 will not shut down due to high temperature. The exhaust hood 10 is placed outside the exhaust port 6 to prevent the ocean air from directly impacting the exhaust electric shutter 12.

[0076] If the oil storage tank 2 leaks, the leaked diesel oil will first enter the first oil storage tank 13 to avoid oil leakage into the ocean. Moreover, when the oil level sensor 14 detects that there is diesel oil in the first oil storage tank 13, the alarm will sound to give a warning.

[0077] A second oil storage tank 20 is provided at the bottom of the container body 3 . Compared with the first oil storage tank 13 , the second oil storage tank 20 can prevent the diesel generator 1 from leaking oil into the ocean.

[0078] The smoke detector 15 and the temperature detector 16 are used to detect whether a fire occurs in the container body 3. If a fire occurs, the fire alarm control box 18 controls the fire extinguishing device 17 to extinguish the fire, and the control cabinet 4 controls the closing of the air inlet electric shutter 9 and the exhaust electric shutter 12.

[0079] The container body 3 is provided with a smoke exhaust pipe 19, and the thick smoke generated by the fire will be discharged from the smoke exhaust pipe 19 to prevent the thick smoke from accumulating in the container body 3 and affecting the subsequent fire fighting of the staff.

[0080] Finally, the dehumidifier 21 is electrically connected to the control machine, which can ensure that the humidity in the container body 3 can be maintained at a certain level, thereby increasing the operating life of the equipment.

[0081] The embodiments described above are only preferred embodiments of the present invention, and are not intended to limit the scope of implementation of the present invention. Therefore, all changes made based on the shape and principle of the present invention should be included in the protection scope of the present invention.
