Among them, it includes an oil vapor collection box. One end of the oil vapor collection box is connected to a diesel engine crankcase ventilation pipe. The end of the oil vapor collection box far from the diesel engine crankcase ventilation pipe is fixedly connected with an oil drain pipe and an exhaust pipe located above the oil drain pipe. Inside the oil vapor collection box, a plurality of filter partitions are sequentially arranged in the direction from the diesel engine crankcase ventilation pipe to the exhaust pipe. A cold water cooling unit for spraying cold water into the interior of the oil vapor collection box to cool the oil vapor is provided on the oil vapor collection box. In the above application document, when the exhaust pipe is used to evacuate the steam inside the oil vapor collection box, the residual oil stains of the steam will enter the filter screen in the exhaust pipe. After long-term operation, the oil stains adhere to the filter screen, which has a great impact on the effect of steam evacuation. Summary of the Utility Model

[0033] Embodiment 1

[0034] See also Figures 1 - 7 As shown in the figure, an oil vapor collection device for a diesel generator set includes an oil vapor collection box 100, and a filter condensation component 200 is assembled inside the oil vapor collection box 100;

[0035] The oil vapor collection box 100 is provided with a scraping device 300 inside, and the scraping device 300 includes a filter 306, the top of the filter 306 is fixedly connected to the inner top of the oil vapor collection box 100, and the inside is interconnected with the exhaust pipe at the top of the oil vapor collection box 100, and the side of the filter 306 is equipped with a rotating wheel 303, and the top surface of the rotating wheel 303 is fixedly connected with a soft scraper 305, and the surface of the soft scraper 305 and the bottom surface of the filter 306 are in contact with each other. The rotating wheel and the soft scraper provide an effective automatic cleaning mechanism for the oil vapor collection box, ensuring the continuous and effective operation of the filter, and improving the performance and reliability of the system. The top of the rotating wheel 303 is rotatably connected with a gear The top of the gear shaft 307 is rotatably connected to the inner top of the oil vapor collection box 100, and the inner wall of the exhaust pipe is equipped with a windmill wheel 302. The gear shaft 307 and the top of the windmill wheel 302 are fixedly connected with a bevel gear rotating box 1 301 and a bevel gear rotating box 2 304. The surface of the bevel gear rotating box 1 301 penetrates and slides on the top of the oil vapor collection box 100. The gear shaft 307 and the windmill wheel 302, the bevel gear rotating box 1 301, and the bevel gear rotating box 2 304 transmit power to each other. The power transmission between the windmill wheel (302) and the impeller 303 is realized through the transmission of the gear shaft 307 and the steering function of the bevel gear rotating box 1 301 and the bevel gear rotating box 2 304.

[0036] During use, first, the oil vapor enters from the right air inlet of the oil vapor collection box 100, and then is filtered by the internal filter condensation assembly 200 to separate the oil and vapor in the oil vapor. Due to gravity, the oil will fall to the bottom inside the oil vapor collection box 100 and converge, and then be discharged through the drain pipe on its left side. At the same time, the exhaust pipe at the top of the oil vapor collection box 100 evacuates the vapor inside. At the connection between the exhaust pipe and the oil vapor collection box 100, a filter net 306 is used for filtration to filter out the residual oil stains in the vapor. During the process of evacuating the vapor, due to the suction force, the wind wheel 302 starts to rotate. This rotational force is transmitted to the gear shaft 307 through the bevel gear transmission box one 301 and the bevel gear transmission box two 304, causing the gear shaft 307 to rotate synchronously. The rotation of the gear shaft 307 drives the blades of the runner 303 and the soft scraper 305 fixed at the top to rotate. The soft scraper 305 fits against the bottom surface of the filter net 306, and continuously scrapes off the accumulated oil stains on the filter net 306 through rotation, ensuring the smooth evacuation of vapor by the exhaust pipe.

[0037] At the same time, in order to clean the ink adhered to the soft scraper, please refer to Figures 6 - 7 , as shown in the figure, a cleaning device 400 is provided at the inner top of the oil vapor collection box 100. The cleaning device 400 includes a positioning groove 404. The top of the positioning groove 404 is fixedly connected to the inner top of the oil vapor collection box 100. The bottom of the positioning groove 404 is fixedly connected with a scraper 405. The overall scraper 405 is made of aluminum material and is in the shape of a flat knife. The flat-knife-shaped scraper 405 is suitable for scraping and cleaning the surface. Aluminum has good thermal conductivity, which has better application value for scenarios that require rapid heat dissipation. A conduit 403 is assembled at the top of the positioning groove 404. Leakage grooves 406 are provided on both side surfaces of the scraper 405. The scraper 405, the connecting shaft 401, and the positioning groove 404 are mutually penetrated. Through the leakage grooves 406, the materials, liquids, or other media scraped by the scraper during operation can flow out through these grooves to assist the scraper 405 in cleaning, which helps to maintain the cleanliness and working efficiency of the scraper 405. The surface of the conduit 403 penetrates through the top of the oil vapor collection box 100, and a connecting shaft 401 is fixedly connected to the end far from the positioning groove 404. A water pump 402 is assembled on the surface of the connecting shaft 401.

[0038] During use, the water pump 402 at the top of the oil vapor collection box 100 fills the scraper 405 with cold water through the connecting shaft 401 and the conduit 403, and the cold water flows out through the leakage grooves 406 on both sides of the scraper 405. At the same time, the scraper 405 and the cold water scrape and clean the ink on the surface of the soft scraper 305, ensuring the practicability of the soft scraper 305 and preventing the soft scraper 305 on the runner 303 from being affected by the ink adhering to it after cleaning the oil stains on the filter net 306, thus affecting the collection of vapor by the exhaust pipe.

[0039] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
