Technical Field
[0001] This invention relates to the field of diesel generator set technology, specifically to a multi-module interconnected explosion-proof and corrosion-resistant diesel generator set. Background Technology
[0002] A diesel generator set is a complete set of power equipment that uses a diesel engine as a power source to drive a synchronous AC generator to generate electricity. A multi-module interconnected explosion-proof and corrosion-resistant diesel generator set is a power equipment suitable for special harsh environments. It mainly generates stable and reliable electrical energy through the coordinated work of multiple functional modules, and also has explosion-proof and corrosion-resistant capabilities.
[0003] While existing multi-module interconnected explosion-proof and corrosion-resistant diesel generator sets can generate stable and reliable electrical energy to power energy storage devices in special harsh environments during actual use, they still have the following shortcomings:
[0004] Existing multi-module interconnected explosion-proof and corrosion-resistant diesel generator sets typically rely on a diesel preheating mechanism for assisted starting in low-temperature environments. However, continuous use of this mechanism results in significant energy consumption. Furthermore, electrically heated diesel preheating mechanisms cannot achieve uniform heating of the diesel fuel, leading to localized overheating or underheating. This, in turn, affects the overall preheating quality of the diesel fuel. If the diesel preheating mechanism is abandoned due to energy consumption or heating uniformity issues, the diesel fuel will remain at a low temperature in low-temperature environments, significantly reducing its fluidity and atomization. This, in turn, directly impacts the combustion efficiency and stability of the multi-module interconnected explosion-proof and corrosion-resistant diesel generator set.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0034] Example 1: Please refer to Figures 1-9As shown, the present invention provides a technical solution: a multi-module interconnected explosion-proof and corrosion-resistant diesel generator set, including a generator mechanism 1. The generator mechanism 1 is used to convert the chemical energy of diesel fuel into mechanical energy through combustion, and then convert the mechanical energy into electrical energy through a generator. The generator mechanism 1 includes a mounting frame 101, a generator body 102 is mounted on the top of the mounting frame 101 near the edge, a diesel engine 103 is mounted on the top center of the mounting frame 101, and the generator body 102 is mounted on the diesel engine 103. The input end of component 2 is connected to the main shaft end of the diesel engine 103. A mounting bracket 104 is installed near the edge of the top of the mounting frame 101, and the mounting bracket 104 is fixed to the surface of the diesel engine 103. A cooling box 105 is installed on top of the mounting bracket 104. An exhaust pipe 106 is connected to the exhaust end of the diesel engine 103. An oil tank 107 is installed on top of the mounting frame 101, and a control cabinet 108 is installed on top of the oil tank 107. An oil pipe 109 is connected to the oil outlet end of the bottom of the oil tank 107. The oil outlet end of the oil pipe 109 is connected to... The diesel engine 103 has an inlet connected to a fuel tank 107. A breather valve 110 is installed on the top of the fuel tank 107, and the interior of the breather valve 110 is connected to the interior of the fuel tank 107 through a through-hole on the top of the fuel tank 107. The coolant outlet of the diesel engine 103 is connected to an outlet pipe 111, the outlet of which extends through the top of the cooling box 105. The coolant inlet of the diesel engine 103 is connected to an inlet pipe 112, the inlet of which extends through the outer wall of the cooling box 105. A connector 113 is installed between the secondary shaft end and the cooling fan shaft input end of the cooling box 105. A fixing bracket 114 is installed on the inner wall of the cooling box 105. A coil 115 is pressed and fixed on the fixing bracket 114. The water inlet end of the coil 115 is connected to the water outlet end of the water inlet pipe 112. The water outlet end of the coil 115 is connected to the water inlet end of the water outlet pipe 111. The water inlet end of the water inlet pipe 112 is connected to the liquid cooling water outlet end of the diesel engine 103. The water outlet end of the water outlet pipe 111 is connected to the liquid cooling water inlet end of the diesel engine 103.
[0035] In this embodiment, when the oil temperature in the fuel tank 107 reaches the normal starting temperature of the diesel generator, the control cabinet 108 directly starts the oil pump in the diesel engine 103. The started oil pump, through the oil pipe 109, draws diesel fuel from the fuel tank 107. The drawn diesel fuel enters the diesel engine 103 and is sprayed out in a mist. Simultaneously, the control cabinet 108 activates the igniter in the diesel engine 103 for electronic ignition, igniting the atomized diesel fuel. The diesel engine 103 then uses the combustion of diesel fuel to generate power, causing the main shaft of the diesel engine 103 to rotate. The rotating main shaft of the diesel engine 103 then drives the input end of the generator body 102 to rotate. The input end of the rotating generator body 102, with the cooperation of other components inside the generator body 102, converts mechanical energy into electrical energy. The generator body 102 then transmits the generated electrical energy to the energy storage device for storage. At the same time, while the main shaft of the diesel engine 103 rotates, its auxiliary... The shaft end will also rotate, and at the same time, the control cabinet 108 will start the cooling water circulation pump in the diesel engine 103. Then, the rotating diesel engine 103's auxiliary shaft end will cooperate with the connector 113 to drive the cooling fan in the cooling box 105 to rotate. At the same time, the circulation pump in the diesel engine 103 will draw away the cooling water in the inlet pipe 112. Then, the drawn-away cooling water will carry away the heat generated during the operation of the diesel engine 103 through heat transfer. Then, the heated cooling water will be transported to the inside of the outlet pipe 111, and then to the inside of the coil 115. When the heated cooling water passes through the inside of the coil 115, the rotating cooling fan in the cooling box 105 will draw away the low-temperature air in the environment. Then, the flowing low-temperature air will carry away the heat carried by the cooling water flowing in the coil 115 through the principle of heat transfer. Then, the heated air will be discharged into the environment from the air outlet of the cooling box 105. This process is repeated. At the same time, the exhaust gas generated by diesel combustion will be transported to the inside of the exhaust pipe 106 and then discharged.
[0036] Example 2: According to Figures 1-4 and Figures 8-10As shown, the generator set 1 is equipped with an auxiliary mechanism 2, which is used to enable the diesel generator set to start normally in low-temperature environments. The auxiliary mechanism 2 includes a set of pipe covers 201, a water pump 204, and a first housing 212. A diversion pipe 202 is installed between the pipe covers 201. The water outlet end of one of the pipe covers 201 is connected to a copper pipe 203 near the top. A water tank 205 is provided around the water pump 204. A heating pipe 209 is provided inside the water tank 205. The water inlet and outlet ends of the water pump 204 are respectively connected to an inlet pipe 210 and a first outlet pipe 211. A second housing 219 is installed on the first housing 212. Sealing strips 213 are adhered to the surfaces of both the first housing 212 and the second housing 219. The top of the first housing 212... Filters 214 are installed at both the water inlet and the bottom inlet / outlet. A sleeve 215 is provided on the outer surface of the copper pipe 203. A second outlet pipe 220 is connected to the water inlet end near the bottom of another pipe cover 201. Multiple cooling fans 216 are evenly distributed on the top of the sleeve 215. The water outlet end near the bottom of the side of the water tank 205 is connected to the water inlet end of the inlet pipe 210. A tank cover 206 is installed on the top of the water tank 205. A first temperature sensor 207 is installed inside one of the through holes in the top of the tank cover 206, with its detection end extending into the interior of the water tank 205. A pressure relief valve 208 is installed inside another through hole in the tank cover 206, and the interior of the pressure relief valve 208 is connected to the interior of the water tank 205. A heat pipe 209 is mounted on the cover 206. The outlet end of the first liquid outlet pipe 211 is connected to the bottom inlet end of the first housing 212. The opposite sides of the two sealing strips 213 are in contact. One end face of the sleeve 215 is fixed to the surface of the water tank 205. A second temperature sensor 217 is provided around the diversion pipe 202. An mounting block 218 is fixed to the outer wall of the second housing 219. The inlet end of the second liquid outlet pipe 220 is connected to the top outlet end of the first housing 212. The power generation mechanism 1 includes a mounting frame 101. A water pump 204 is mounted on the top of the mounting frame 101. A water tank 205 is mounted on the top of the mounting frame 101. A diesel engine 103 is mounted in the middle of the top of the mounting frame 101. The mounting block 218 is mounted on the top of the diesel engine 103. On the surface of the diesel engine 103, an exhaust pipe 106 is connected to the exhaust end of the diesel engine 103. The exhaust pipe 106 is located between the first housing 212 and the second housing 219. An oil tank 107 is installed on the top of the mounting frame 101, and a control cabinet 108 is installed on the top of the oil tank 107. The outlet end of the diverter pipe 202 is fixedly fixed through the outer wall and the inner wall of the oil tank 107. The other end of the sleeve 215 is fixed to the outer wall of the oil tank 107. A second temperature sensor 217 is installed on the outer wall of the oil tank 107 near the bottom. The detection end of the second temperature sensor 217 extends into the interior of the oil tank 107. Stabilizers 3 are installed on the top of the mounting frame 101 and the surface of another pipe cover 201. There are two stabilizers 3 on the mounting frame 101.The number of stabilizers 3 on the other pipe cover 201 is one.
[0037] In this embodiment, when the multi-module interconnected explosion-proof and corrosion-resistant diesel generator set needs to be used in a low-temperature environment, the heating element 209 and the first temperature sensor 207 are first activated using the control cabinet 108. The activated heating element 209 heats the water inside the water tank 205. Simultaneously, the activated first temperature sensor 207 measures the temperature of the water inside the water tank 205 in real time and transmits each detected water temperature data as an electrical signal to the controller in the control cabinet 108. The controller in the control cabinet 108 then compares the received water temperature data with a pre-set temperature threshold. When the water temperature data received by the controller in the control cabinet 108 is lower than the pre-set temperature threshold, the controller will initiate a temperature threshold adjustment. When the set temperature threshold is low, the control cabinet 108 will not stop the heating element 209. When the water temperature data received by the controller in the control cabinet 108 is the same as the temperature threshold preset by the controller in the control cabinet 108, the control cabinet 108 will stop the heating element 209. At this time, the control cabinet 108 will start the water pump 204 and the second temperature sensor 217. The water pump 204, in cooperation with the inlet pipe 210, will pump the heated water out of the water tank 205 and then deliver it to the inside of the first outlet pipe 211. After that, it will be delivered to the space formed by the first housing 212, the two sealing strips 213 and the second housing 219, and then to the inside of the second outlet pipe 220. After that, it will be delivered to the inside of another pipe cover 201. The heated water is then diverted into each pipe of the diversion pipe 202. As the heated water passes through each pipe of the diversion pipe 202, it heats the diesel fuel inside the fuel tank 107 uniformly through heat exchange. The cooled water then enters one of the pipe covers 201, then the copper pipe 203, and finally flows back to the water tank 205 for a new cycle. Simultaneously, the second temperature sensor 217 monitors the oil temperature inside the fuel tank 107 in real time and transmits the detected oil temperature data as an electrical signal to the controller in the control cabinet 108. The controller in the control cabinet 108 then compares the received oil temperature data with a pre-set temperature threshold. When the control cabinet 108... When the oil temperature data received by the controller in 8 is lower than the temperature threshold preset by the controller in control cabinet 108, control cabinet 108 will not stop the water pump 204. When the oil temperature data received by the controller in control cabinet 108 is the same as the temperature threshold preset by the controller in control cabinet 108, control cabinet 108 will stop the water pump 204. When exhaust gas enters the interior of exhaust pipe 106 and exits from the outlet of exhaust pipe 106, and the diesel fuel in fuel tank 107 needs to be heated, control cabinet 108 will directly start the water pump 204 to continue circulating the water in water tank 205. When water enters the space composed of the first housing 212, two sealing strips 213, and the second housing 219, it will be heated by heat transfer.The water flowing into this space can be heated, and then the heated water can be used to evenly heat the diesel fuel inside the fuel tank 107. When the water temperature inside the water tank 205 exceeds the temperature threshold preset by the controller in the control cabinet 108, the control cabinet 108 will activate all the cooling fans 216. These fans, in conjunction with the sleeve 215, draw in low-temperature air from the environment. Using the flowing low-temperature air and the principle of heat exchange, the high-temperature steam inside the entire circulation pipe is cooled into liquid. This process repeats, maintaining a suitable oil temperature inside the fuel tank 107 while reducing energy consumption.
[0038] The overall effect and working principle of the mechanism are as follows:
[0039] In the preparation stage, first connect the control cabinet 108, diesel engine 103, water pump 204, first temperature sensor 207, heating pipe 209, all cooling fans 216 and second temperature sensor 217 according to electrical connection safety guidelines and drawing requirements. Then connect the generator body 102 to the energy storage device. Next, turn on the controller in the control cabinet 108 and set the parameters such as the water pump 204 inlet and outlet speed, cooling fan 216 wind speed and heating pipe 209 temperature. Then inject an appropriate amount of clean water into the water tank 205 and the water circulation system (composed of inlet pipe 112, outlet pipe 111, coil 115 and diesel engine 103 liquid cooling mechanism). Then inject an appropriate amount of diesel into the fuel tank 107.
[0040] During the preheating phase, when the multi-module interconnected explosion-proof and corrosion-resistant diesel generator set needs to be used in a low-temperature environment, the heating element 209 and the first temperature sensor 207 are activated using the control cabinet 108. The activated heating element 209 heats the water inside the water tank 205. Simultaneously, the activated first temperature sensor 207 measures the water temperature inside the water tank 205 in real time and transmits each detected water temperature data as an electrical signal to the controller in the control cabinet 108. The controller in the control cabinet 108 then compares the received water temperature data with a pre-set temperature threshold. When the water temperature is lower than the temperature threshold preset by the controller in control cabinet 108, control cabinet 108 will not stop the heating element 209. When the water temperature data received by the controller in control cabinet 108 is the same as the temperature threshold preset by the controller in control cabinet 108, control cabinet 108 will stop the heating element 209. At this time, control cabinet 108 will start the water pump 204 and the second temperature sensor 217. The water pump 204, in cooperation with the inlet pipe 210, will pump the heated water out of the water tank 205 and then deliver it to the inside of the first outlet pipe 211. After that, it will be delivered to the space composed of the first housing 212, two sealing strips 213 and the second housing 219, and then to the second outlet pipe 211. The heated water flows into the interior of tank 107, then into another pipe cover 201, and finally into each pipe of the distribution pipe 202. As the heated water passes through each pipe of the distribution pipe 202, it heats the diesel fuel inside tank 107 evenly through heat exchange. The cooled water then enters one of the pipe covers 201, then into copper pipe 203, and finally flows back into water tank 205 for a new cycle. Simultaneously, the second temperature sensor 217 monitors the oil temperature inside tank 107 in real time and transmits each detected oil temperature data as an electrical signal to the controller in control cabinet 108. The controller in control cabinet 108 then receives the data... The oil temperature data is compared with the temperature threshold preset by the controller in control cabinet 108. When the oil temperature data received by the controller in control cabinet 108 is lower than the temperature threshold preset by the controller in control cabinet 108, the controller in control cabinet 108 will not stop the water pump 204 (of course, when the water temperature inside the water tank 205 drops, the heating element 209 will also start again). When the oil temperature data received by the controller in control cabinet 108 is the same as the temperature threshold preset by the controller in control cabinet 108, the controller in control cabinet 108 will stop the water pump 204 (after the water pump 204 stops for the first time, the controller in control cabinet 108 will not restart the heating element 209. After resetting, the previous operation steps can be continued).
[0041] During the diesel generator's power generation phase, when the oil temperature in the fuel tank 107 reaches the normal starting temperature for the diesel generator, the control cabinet 108 directly starts the fuel pump in the diesel engine 103. The pump, through the fuel line 109, draws diesel fuel from the fuel tank 107. This drawn-out diesel fuel enters the diesel engine 103 and is sprayed out in a mist. Simultaneously, the control cabinet 108 activates the igniter in the diesel engine 103 for electronic ignition, igniting the atomized diesel fuel. The diesel fuel then burns, generating power to rotate the main shaft of the diesel engine 103. This rotating main shaft drives the input end of the generator body 102. The input end of the rotating generator body 102, with the assistance of other internal components, converts mechanical energy into electrical energy. The generator body 102 then transmits the generated electrical energy to an energy storage device for storage. Simultaneously, the main shaft of the diesel engine 103 rotates... The secondary shaft end will also rotate, and at the same time, the control cabinet 108 will start the cooling water circulation pump in the diesel engine 103. Then, the rotating secondary shaft end of the diesel engine 103 will drive the cooling fan in the cooling box 105 to rotate through the connector 113. At the same time, the circulation pump in the diesel engine 103 will draw away the cooling water in the inlet pipe 112. Then, the drawn-away cooling water will carry away the heat generated during the operation of the diesel engine 103 by heat transfer. Then, the heated cooling water will be transported to the inside of the outlet pipe 111, and then to the inside of the coil 115. When the heated cooling water passes through the inside of the coil 115, the rotating cooling fan in the cooling box 105 will draw away the low-temperature air in the environment. Then, the flowing low-temperature air will carry away the heat carried by the cooling water flowing in the coil 115 by heat transfer. Then, the heated air will be discharged into the environment from the air outlet of the cooling box 105. This process can be repeated. At the same time, the exhaust gas generated by diesel combustion will be transported to the inside of the exhaust pipe 106 and then discharged.
[0042] During the heat preservation stage, when exhaust gas (carrying heat) enters the interior of exhaust pipe 106 and exits from the outlet of exhaust pipe 106, and the diesel fuel inside fuel tank 107 needs to be heated, the water pump 204 is directly started by control cabinet 108 to continue circulating the water inside water tank 205. When water enters the space formed by the first housing 212, two sealing strips 213, and the second housing 219, the water flowing into this space can be heated through the principle of heat transfer. Subsequently, the heated water is used to evenly heat the diesel fuel inside fuel tank 107. When the water temperature inside water tank 205 is higher than that of the control cabinet... When the temperature threshold preset by the controller in 108 is reached, the control cabinet 108 will start all the cooling fans 216. The cooling fans 216, in cooperation with the sleeve 215, will draw in the low-temperature air from the environment. Then, by using the flow of low-temperature air and the principle of heat exchange, the high-temperature steam inside the entire circulation pipe (the water transported by the circulating water pump 204) will be cooled into liquid. (When the pressure relief valve 208 releases pressure, the high-temperature steam will not be discharged, thus avoiding a decrease in the liquid volume inside the entire circulation pipe). This process repeats, which can keep the oil temperature inside the oil tank 107 at a suitable temperature and reduce power consumption.
[0043] All components of the diesel generator are made of explosion-proof and corrosion-resistant materials, and the breather valve 110 ensures that the pressure inside the fuel tank 107 is the same as the environment.
[0044] Among them, the generator body 102, diesel engine 103, cooling box 105, oil tank 107, control cabinet 108, breather valve 110, water pump 204, first temperature sensor 207, pressure relief valve 208, heating tube 209, cooling fan 216 and second temperature sensor 217 are all existing technologies, and their models can be selected according to the actual situation. They will not be explained in detail here.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
