DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] Example 1: Please refer to Figure 1 - Fig.12 As shown, this embodiment is a ventilation and temperature control structure of a diesel generator set silent box, including a silent box 1, a top frame 102 is arranged on the top of the silent box 1, a bottom air inlet 103 and an external power connection box 3 are arranged on the bottom side wall, and a control panel is arranged inside the external power connection box 3, a base 2 is arranged at the bottom of the silent box 1, an air guide mechanism 4 is arranged at the bottom of the top frame 102, the air guide mechanism 4 includes an outer guide frame 402 and an exhaust fan 405, a cold medium storage box 7 is arranged on the side of the exhaust fan 405, and a circulating pump 701 is arranged on the side of the cold medium storage box 7, and an adjustable air frame 6 is arranged on the inner wall of the outer guide frame 402; A heat exhaust channel 201 is provided through the bottom of both sides of the base 2, a box cover 101 is hinged on the bottom surface of the silent box 1, and a hot air suction port 104 connected to the heat exhaust channel 201 is provided on the top of the inner wall of the silent box 1. The heat generated by the diesel generator during operation is collected inside the silent box 1, and the exhaust fan 405 starts to start. Under the normal low-load operation state, an air channel that penetrates the silent box 1 and is connected to the exhaust fan 405 is provided on the top of the bottom air inlet 103, and some heat exchange fins 604 are provided inside the air channel. The exhaust fan 405 draws air from the low-altitude environment of the external environment along the bottom air inlet 103 through the air channel. When the air passes through the air channel, the heat exchange fins 604 perform heat exchange treatment on it, so that the temperature of the air entering the exhaust fan 405 is reduced, and the air is transported into the silent box 1; A plurality of cold air outlets 105 are arranged below the hot air suction port 104, the bottom of the bottom air inlet 103 is connected to the heat exhaust channel 201, and an inclined filter plate 106 is arranged on the inner wall of the bottom of the bottom air inlet 103. When the air passes through the bottom air inlet 103, impurities therein are intercepted by the inclined filter plate 106. After the impurities continue to accumulate, they fall into the heat exhaust channel 201 along the bottom of the bottom air inlet 103 due to their own weight and the vibration existing during the operation of the diesel generator. The inside of the silent box 1 is accompanied by continuous injection of cold air, which causes the hot air to gather at the top of the silent box 1 and enter the heat exhaust channel 201 along the hot air suction port 104. The hot air flows in the heat exhaust channel 201 and carries the fallen dust out of the equipment; the air guide mechanism 4 is symmetrically provided with corner columns 401 connected to the top frame 102 at the four corners, the outer wall edge of the outer guide frame 402 is provided with jet outlets 403, and the middle frame of the outer guide frame 402 is provided with a plurality of fine filters 404.

[0017] Embodiment 2: This embodiment is a ventilation and temperature control structure of a diesel generator set silent box, including an adjustable air frame 6 with a movable filter plate 601 and a vibration motor 602 arranged inside, a cone bin 603 arranged on the side of the adjustable air frame 6, and a heat exchange fin 604 arranged inside the cone bin 603, a top cover 5 arranged above the adjustable air frame 6, a frustum 501 arranged at the bottom of the top cover 5, and a spiral plate 502, a cross frame 503 and a curved plate frame 504 arranged on the top of the frustum 501; The outer wall of the adjustable air frame 6 is attached to the inner wall of the outer guide frame 402, the movable filter plate 601 is clamped inside the adjustable air frame 6, a vibration frame connected to the movable filter plate 601 is provided at the bottom of the vibration motor 602, and a dust collecting tank 606 is provided below the movable filter plate 601, a regulating valve 605 connected to the exhaust fan 405 is provided on the outer wall of the cone bin 603, and the heat exchange fins 604 are embedded inside the cone bin 603; When the high load continues, the regulating valve 605 opens, causing the adjustable air rack 6 to be connected to the exhaust fan 405. The exhaust fan 405 extracts external air through the adjustable air rack 6 along the outer guide frame 402. The external air first passes through the fine filter 404 and then enters the adjustable air rack 6, and then contacts the movable filter plate 601 again, causing the air to be filtered twice. The air passing through the movable filter plate 601 enters the cone bin 603, and enters the exhaust fan 405 along the cone bin 603 and the regulating valve 605. The air passing through the cone bin 603 contacts the heat exchange fins 604, causing the air to exchange heat and cool down. The exhaust fan 405 guides the air into the multiple groups of cold air outlets 105 through the pipe fittings. The cone 501 is clamped on the inner wall of the middle part of the top frame 102, and the curved plate frame 504 is fixed at the top center of the cone 501. The curved plate frame 504 is equidistantly staggered with interconnected curved plates 507. The cold medium storage box 7 guides the cold medium into multiple groups of heat exchange fins 604 through the circulating pump 701, so that the heat exchange fins 604 are in contact with the passing air for heat exchange, which greatly reduces the air temperature. The warm and cold medium after heat exchange in the heat exchange fins 604 is transported along the pipeline to the return pipe rack on the bottom wall of the top cover 5. The bottom of the return pipe rack is provided with spiral plate 502, The branch pipe connected with the cross frame 503 and the curved plate frame 504 guides the warm and hot medium into the multiple groups of spiral plate plates 502, the cross frame 503 and the curved plate frame 504. The spiral plate plates 502, the side plates 505 and the curved plates 507 are all provided with flow chambers, which promote the warm and hot medium to flow from top to bottom along the flow chamber. The warm and hot medium is affected by the main structure of the spiral plate plates 502, the cross frame 503 and the curved plate frame 504, and forms a plurality of flow routes with different trajectories. The warm and hot medium contacts with the air inside the top cover 5, which promotes the excess heat on the warm and hot cold medium to be diffused and discharged with the air flow. The cross frame 503 is installed side by side on both sides of the curved plate frame 504. A plurality of side plates 505 are arranged on the surface of the cross frame 503, and a plurality of through openings 506 are arranged through the surface of the side plates 505. Sleeves 508 are arranged on the top and bottom of the spiral plate 502. A return pipe rack connected to the spiral plate 502, the cross frame 503 and the curved plate frame 504 is arranged on the bottom wall of the top cover 5. The top cover 5 is located on the top of the soundproof box 1. When the diesel generator is used in the construction site, it is affected by the natural air flow in the external environment and the position height of the top cover 5. The naturally flowing air enters the top cover 5 along the top area of ​​the fine filter 404. The naturally flowing air is affected by the structures of the plurality of spiral plates 502, the cross frame 503 and the curved plate frame 504, which promotes the air to flow between the plurality of the above structures.

[0018] Embodiment 3: This embodiment is a ventilation and temperature control structure of a diesel generator set silent box, including a plurality of groups of power sockets at the bottom of an external power connection box 3, and a control panel embedded in the top box body of the external power connection box 3, a data monitoring platform is arranged inside the control panel, and the data monitoring platform is communicatively connected with an operation data acquisition unit, a data comprehensive analysis unit and a component control unit; When the data supervision platform generates a supervision instruction, the generated supervision instruction is sent to the operation data acquisition unit. After receiving the supervision instruction, the operation data acquisition unit immediately obtains the temperature fluctuation value BDz inside the silent box 1 and the air flow parameters around the top cover 5. The temperature fluctuation value BDz represents the influence of the heat generated by the diesel generator under load operation on the internal temperature environment of the silent box 1, which is collected by multiple groups of temperature sensors installed inside the silent box 1. The air flow parameters include the values ​​of air flow in directions a1, a2, a3 and a4 around the top cover 5 through the fine filter 404, which are collected by the air flow sensor installed on the inner wall of the fine filter 404, and the temperature fluctuation value BDz and the air flow parameters are sent to the data comprehensive analysis unit; After receiving the temperature fluctuation value BDz and the air flow parameter, the data comprehensive analysis unit retrieves the preset temperature fluctuation range threshold value pre-stored and entered from the data supervision platform for comparison and analysis with the temperature fluctuation value BDz: If the temperature fluctuation value BDz is greater than the middle value of the preset temperature fluctuation range threshold, it is determined that the temperature inside the silent box 1 is overheated in this state, and a temperature alarm signal is generated. The generated temperature alarm signal is sent to the component control unit, and the component control unit controls the regulating valve 605 to open, so that the adjustable air rack 6 is connected to the exhaust fan 405. The exhaust fan 405 draws external air along the outer guide frame 402 through the adjustable air rack 6. The external air first enters the adjustable air rack 6 after being intercepted and filtered along the fine filter 404, and then contacts the movable filter plate 601 again, so that the air is filtered twice. The air passing through the movable filter plate 601 enters the cone bin 603, and enters the exhaust fan 405 along the cone bin 603 and the regulating valve 605. The air passing through the cone bin 603 contacts the heat exchange fins 604, so that the air is heat exchanged and cooled. The exhaust fan 405 guides the air into the multiple groups of cold air outlets 105 through the pipe fittings. If the temperature fluctuation value BDz is less than the middle value of the preset temperature fluctuation range threshold, no signal is generated; After the temperature alarm signal is generated, the data comprehensive analysis unit retrieves the preset air flow velocity value stored in the data supervision platform and compares it with the air flow parameters: If a1 is greater than the preset air flow velocity value, and a2, a3 and a4 are all less than the preset air flow velocity values, it is determined that the direction of a1 is the downwind inlet, and a first-level air guide signal is generated; If a2 is greater than the preset air flow velocity value, and a1, a3 and a4 are all less than the preset air flow velocity values, it is determined that the direction of a2 is the downwind inlet, and a secondary air guide signal is generated; If a3 is greater than the preset air flow velocity value, and a1, a1 and a4 are all less than the preset air flow velocity values, it is determined that the direction of a3 is the downwind inlet, and a level 3 air guide signal is generated; If a4 is greater than the preset air flow velocity value, and a1, a2 and a3 are all less than the preset air flow velocity values, it is determined that the direction of a4 is the downwind inlet, and a level 4 air guide signal is generated; The generated air guide signal is sent to the component control unit, and the component control unit starts the corresponding plan according to the level of the received air guide signal. The corresponding plans include the first-level plan, the second-level plan, the third-level plan and the fourth-level plan. When the first-level plan is started, the regulating valves 605 located in the directions of a2, a3 and a4 are closed, and the exhaust fan 405 guides the airflow through the fine filter 404 through the adjustable air rack 6 in the direction of a1, and forms a negative pressure drainage environment near the fine filter 404 in the area, so that the external air passes through the fine filter 404 and enters between the cone 501 and the top cover 5, so that the external air is accelerated to flow along this direction through the spiral plate 502, the cross frame 503 and the curved plate frame 504, and the heat diffused on the accelerator surface is reduced; At the same time, the jet port 403 on the outer guide frame 402 located in the directions of a2, a3 and a4 starts to operate, and a micro fan embedded in the top inner wall of the soundproof box 1 is provided at the bottom of the outer guide frame 402. The micro fan is connected to the hot air suction port 104 through a pipeline, and guides part of the hot air inside the soundproof box 1 into the jet port 403, and is ejected from the jet port 403, forming an outward-pushing airflow around the outer guide frame 402 in the directions of a2, a3 and a4, which is used to guide the air between the top cover 5 and the cone 501 to flow outward.

[0019] In combination with Example 1, Example 2 and Example 3, it can not only constitute the vibration screen separation of the filtered impurities, but also cooperate with the hot air flow trajectory that continuously squeezes out the leaked hot air inside the soundproof box 1 to entrain and discharge it to the outside of the device, forming a multi-directional, large-volume collective suction, which is convenient for adaptive cooling and regulation of high-load diesel generators under continuous operation. According to the air flow direction of the surrounding environment of the top cover 5, the adjustable air rack 6 and the exhaust fan 405 are precisely controlled, which is used to achieve coordinated guidance of the heat diffused in the top cover 5 to leak out in combination with the air flow state in the environment during operation.
