Description

Technical Field

[0001] The invention relates to the technical field of injection cooling, in particular to a diesel engine flywheel cooling system based on injection technology. Background Art

[0002] At present, the flywheel of a diesel engine is an important part of a diesel engine. During the working process of a diesel engine, the piston reciprocates in the cylinder and drives the crankshaft to rotate through the connecting rod. However, the rotation of the crankshaft is not uniform. During the power stroke, the gas pressure pushes the piston to work, the crankshaft will obtain greater energy, and the speed tends to accelerate. During other strokes, energy needs to be consumed to maintain the continued rotation of the crankshaft. The flywheel uses its own large moment of inertia to store excess energy during the power stroke, and then releases energy during other strokes, so that the crankshaft can rotate at a relatively uniform speed, ensuring the stability of the diesel engine, avoiding excessive speed fluctuations, making the operation of the diesel engine more stable and reliable, and the output power more uniform. As the flywheel rotates, the air around the flywheel is driven. When water mist is sprayed onto the flywheel surface for cooling, the flowing air drives the water mist, making it impossible for the water mist to contact the flywheel for cooling. At the same time, the connection between the flywheel and the diesel engine bearing is prone to rust after contact with water. Summary of the invention

[0003] To achieve the above objectives, the present invention is implemented through the following technical solutions: A diesel engine flywheel cooling system based on injection technology, comprising: A liquid storage mechanism, which is used to store liquid and filter the liquid, a connecting cylinder is fixedly installed on the outside of the liquid storage mechanism, and a connecting pipe is installed on the top of the outside of the liquid storage mechanism; A spray mechanism, which is used to spray coolant onto the surface of the flywheel, and is installed outside the liquid storage mechanism; An outer cover mechanism, which is used to block splashing liquid and control the air flow on the flywheel surface, and is installed on the outside of the injection mechanism; The nozzle is provided with a spring which is arranged on the outer wall of the nozzle and the outer wall of the nozzle is provided with a spring which is arranged on the outer wall of the nozzle.

[0004] Preferably, the outer cover disk is a conical cover, and a scraper is fixedly installed on the outer side of the fixed disk. The scraper is evenly installed along the center position of the fixed disk and is located between the nozzles. A support block is fixedly installed on the outer side of the fixed disk. The scraper cooperates with the support block, and in the process of the flywheel rotating to drive the surface water outward, the flywheel is divided into multiple areas by the scraper. At the same time, when there is a lot of water on the flywheel surface, the water moving outward can accelerate the speed of outward movement after contacting the scraper, so that the water quickly passes over the fixed ring and is conducted outward through the gap between the support blocks. When there is a lot of water on the flywheel surface, it is quickly discharged to avoid excessive water on the flywheel surface. The support blocks are evenly installed along the center position of the fixed disk and are located on the outer side of the scraper. A fixing ring is fixedly installed on the end of the support block away from the fixed disk.

[0005] Preferably, the outer cover mechanism includes an outer ring disk, which is fixedly mounted on the outer side of the fixed disk, and an air guide plate is fixedly mounted on the outer side of the outer ring disk, and the air guide plate cooperates with the outer arc cover to drive the air inside the flywheel to move toward the outer arc cover during rotation and be led out through the through hole. In the process of driving the air flow, the air drives the water on the surface of the flywheel to move outward, fully contacting the flywheel to absorb heat, and at the same time, the flowing air cooperates with the water on the surface of the flywheel to cool the flywheel, thereby improving the cooling effect. The air guide plates are evenly installed along the center position of the outer ring disk, and a connecting ring is fixedly mounted on one side of the outer ring disk close to the liquid storage mechanism, and an outer clamping block is fixedly mounted on the outer side of the connecting ring. The outer clamping block is arranged along the circle of the connecting ring. The outer clamp block is evenly installed at the center position, and the opposite surfaces of the outer clamp block are provided with grooves. The grooves of the outer clamp block cooperate with the through holes of the outer arc cover, so that when the inner air and the water on the flywheel surface are led out, the water and the air are led out along the through holes of the outer arc cover, and the splashing water is blocked to prevent a large amount of water from splashing around during the rotation of the flywheel. At the same time, after the inner air is led out, the outer air is led out along the gap between the outer clamp block and the arc surface of the flywheel, and the water is restricted during the introduction process to prevent the water on the flywheel surface from being led out along the gap and splashing. The outer side of the outer clamp block is fixedly installed with an outer arc cover, the outer side of the outer arc cover is a conical inclined surface, and an arc ring is provided on the side of the outer arc cover close to the liquid storage mechanism, and the outer side of the arc ring is evenly provided with through holes.

[0006] Preferably, the liquid storage mechanism includes a cavity ring, an annular cavity is provided inside the cavity ring, and a fixed tube is fixedly installed on the top of the outer side of the cavity ring, one end of the fixed tube is fixedly connected to the connecting tube, the outer side of the cavity ring is fixedly connected to one end of the connecting tube, a rotating cover is rotatably installed at the annular cavity of the cavity ring, an annular groove is provided on the outer side of the rotating cover close to the connecting tube, a sealing ring is fixedly installed at the annular groove of the rotating cover, a rotating groove is provided on the outer side of the rotating cover away from the connecting tube, and a gasket is rotatably installed at the rotating groove of the rotating cover, the rotating cover is rotatably adapted to the inner wall of the cavity ring through the gasket, circular grooves are evenly provided on the outer side of the rotating cover, and the A connecting pipe is fixedly installed at the circular groove of the rotating cover, and the inner wall of the connecting pipe is fixedly connected to the outer side of the nozzle. The inner wall of the rotating cover is fixedly connected to an arc-shaped filter disk, and the sprayed water is filtered by the arc-shaped filter disk to avoid clogging of the spray hole. At the same time, during the rotation process, the arc-shaped protrusion at the center position cooperates with the introduced water, so that the introduced water evenly impacts the arc-shaped protrusion position, and cooperates with the rotation of the arc-shaped filter disk to make the impurities at the filter hole position be flushed away by the water flow, avoiding clogging of the filter hole position, affecting the flow of water, and resulting in the inability to spray water mist to cool the flywheel. The center position of the outer side of the arc-shaped filter disk is arc-shaped and protrudes toward the connecting tube and filter holes are evenly opened.

[0007] The present invention provides a diesel engine flywheel cooling system based on injection technology. It has the following beneficial effects: 1. The diesel engine flywheel cooling system based on injection technology, through the cooperation of the outer cover plate and the groove ring, guides the water mist toward the flywheel during the process of spraying water mist from the nozzle hole. At the same time, the outer cover plate blocks the water mist to prevent the air flow driven by the flywheel, so that the water mist is carried out by the flowing air without contacting the flywheel to absorb heat, resulting in poor heat absorption effect, affecting the cooling effect. At the same time, the groove ring blocks the water from moving inward to prevent the connection position between the flywheel and the diesel engine bearing from rusting after contacting water.

[0008] 2. The diesel engine flywheel cooling system based on injection technology cooperates with the support block through the scraper. When the flywheel rotates to drive the water on the surface outward, the flywheel is divided into multiple areas through the scraper. At the same time, when there is a lot of water on the flywheel surface, the water moving outward can accelerate the speed of outward movement after contacting the scraper, so that the water quickly passes over the fixed ring and is conducted outward through the gap between the support blocks. When there is a lot of water on the flywheel surface, it is quickly discharged to avoid excessive water on the flywheel surface.

[0009] 3. The diesel engine flywheel cooling system based on injection technology cooperates with the outer arc cover through the air guide plate. During the rotation, the air inside the flywheel is driven to move toward the outer arc cover and is discharged through the through hole. In the process of driving the air flow, the air drives the water on the surface of the flywheel to move outward, fully contacting the flywheel to absorb heat. At the same time, the flowing air cooperates with the water on the flywheel surface to cool the flywheel, thereby improving the cooling effect.

[0010] Fourth, the diesel engine flywheel cooling system based on the injection technology cooperates with the notch of the outer clamp block and the through hole of the outer arc cover. When the inner air and the water on the flywheel surface are discharged, the water and the air are discharged along the through hole of the outer arc cover, and the splashing water is blocked to prevent a large amount of water from splashing around during the rotation of the flywheel. At the same time, after the inner air is discharged, the outer air is discharged along the gap between the outer clamp block and the arc surface of the flywheel. The water is restricted during the introduction process to prevent the water on the flywheel surface from being discharged along the gap and splashing.

[0011] 5. The diesel engine flywheel cooling system based on injection technology filters the sprayed water through the arc-shaped filter disc to avoid clogging of the spray hole. At the same time, during the rotation process, the arc-shaped protrusion at the center position cooperates with the introduced water to make the introduced water evenly impact the arc-shaped protrusion position, and cooperate with the rotation of the arc-shaped filter disc to make the impurities at the filter hole position be flushed away by the water flow, avoiding clogging of the filter hole position, affecting the flow of water, and resulting in the inability to spray water mist to cool the flywheel.

[0014] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0015] The first embodiment, as Figure 1 to Figure 2 and Figures 5 to 8 As shown, the present invention provides a technical solution: a diesel engine flywheel cooling system based on injection technology, comprising: A liquid storage mechanism 3, which is used to store liquid and filter the liquid. A connecting tube 4 is fixedly installed on the outside of the liquid storage mechanism 3, and a connecting pipe 5 is installed on the top of the outside of the liquid storage mechanism 3; The spray mechanism 2 is used to spray the coolant onto the surface of the flywheel, and the spray mechanism 2 is installed outside the liquid storage mechanism 3; An outer cover mechanism 1, which is used to block splashing liquid and control the air flow on the flywheel surface, and is installed on the outside of the injection mechanism 2; The spray mechanism 2 includes a fixed disk 204, and a nozzle 208 is fixedly installed on the inner wall of the fixed disk 204. The nozzle 208 is evenly installed along the center of the fixed disk 204. The end of the nozzle 208 close to the liquid storage mechanism 3 is fixedly connected to the liquid storage mechanism 3. The outer end of the nozzle 208 away from the liquid storage mechanism 3 is evenly provided with spray holes, and a sliding disk 209 is slidably installed on the inner wall of the nozzle 208. It is connected to the flywheel flange through the fixed cylinder 201, so that the fixed disk 204 is driven during the rotation of the flywheel. During the rotation, the water introduced by the liquid storage mechanism 3 enters the interior of the nozzle 208, and the water pressure is transmitted to the spring 210 through the sliding disk 209. The water pressure compresses the spring 210 to deform, causing the sliding disk 209 to slide , open the spray hole of the nozzle 208, so that water is sprayed out from the spray hole of the nozzle 208. During the water spraying process, the sprayed water mist is sprayed to the flywheel surface through the guidance and blocking of the outer cover plate 207, and the heat of the flywheel is transferred to the water contacting the flywheel surface, thereby reducing the temperature of the flywheel. A spring 210 is fixedly installed between the sliding plate 209 and the inner wall of the nozzle 208. During the rotation of the flywheel, when the amount of water attached to the flywheel surface through the groove ring 206 is large, the water is blocked from flowing inward. The outer side of the nozzle 208 is fixedly installed with the outer cover plate 207, the inner wall of the fixed plate 204 is fixedly installed with the fixed cylinder 201, the outer side of the fixed cylinder 201 is fixedly installed with the groove ring 206, and the outer side of the groove ring 206 is provided with a concave ring groove.

[0016] The outer cover disk 207 is a conical cover, and a scraper 203 is fixedly installed on the outer side of the fixed disk 204. The scraper 203 is evenly installed along the center position of the fixed disk 204, and the scraper 203 is located between the nozzles 208. A support block 205 is fixedly installed on the outer side of the fixed disk 204. The support block 205 is evenly installed along the center position of the fixed disk 204, and the support block 205 is located on the outer side of the scraper 203. After the water mist contacts the flywheel surface, the centrifugal force of the rotation of the flywheel causes the water on the flywheel surface to move to the outside of the flywheel, and with the blocking of the scraper 203, the water moves quickly to the outside along the scraper 203. After the water on the flywheel surface reaches a certain amount, it passes over the fixed ring 202 and continues to flow to the outside along the gap between the support blocks 205. The support block 205 is fixedly installed with a fixed ring 202 at one end away from the fixed disk 204.

[0017] The second embodiment is based on the first embodiment. Figure 3 to Figure 4As shown, the outer cover mechanism 1 includes an outer ring disk 14, which is fixedly installed on the outer side of the fixed disk 204, and an air guide plate 15 is fixedly installed on the outer side of the outer ring disk 14, and the air guide plate 15 is evenly installed along the center position of the outer ring disk 14. A connecting ring 11 is fixedly installed on the side of the outer ring disk 14 close to the liquid storage mechanism 3, which is clamped on the arc surface of the outer side of the flywheel through the outer clamping block 13, and is fixedly connected to the fixed disk 204 through the outer ring disk 14. When the fixed disk 204 is driven by the rotation of the flywheel, the outer ring disk 14 is also driven to rotate. During the rotation of the outer ring disk 14, the air guide plate 15 is driven to rotate along the center position of the outer ring disk 14, and an outer clamping block 13 is fixedly installed on the outer side of the connecting ring 11, and the outer clamping block 13 is evenly installed along the center position of the connecting ring 11. , and the opposite surfaces of the outer clamping block 13 are provided with notches, the outer side of the outer clamping block 13 is fixedly installed with an outer arc cover 12, the outer side of the outer arc cover 12 is a conical inclined surface, and the side of the outer arc cover 12 close to the liquid storage mechanism 3 is provided with an arc ring. During the rotation process, the air inside the flywheel is driven to flow outward through the air guide plate 15, so that the air flows outward with the heat inside, and drives the water on the surface of the flywheel to flow outward, so that the air and the water thrown off the flywheel surface contact the inner wall of the outer arc cover 12, and the water and air are discharged through the through holes at the arc ring of the outer arc cover 12. During the process of air discharge, the inner air pressure is reduced, and the air on the outside is discharged through the gap between the outer clamping block 13 and the flywheel, and enters the inner side of the flywheel, and the outer side of the arc ring is evenly provided with through holes.

[0018] The third embodiment is based on the first and second embodiments. Figures 9 and 10 As shown, the liquid storage mechanism 3 includes a cavity ring 31, an annular cavity is provided inside the cavity ring 31, and a fixed pipe 35 is fixedly installed on the top of the outer side of the cavity ring 31, one end of the fixed pipe 35 is fixedly connected to the connecting pipe 5, and the outer side of the cavity ring 31 is fixedly connected to one end of the connecting tube 4. When water is introduced into the cavity ring 31 through the connecting tube 5, the water enters the cavity ring 31 and enters the interior of the rotating cover 33 at the same time. At the same time, the sealing ring 37 prevents the water from seeping out from between the rotating cover 33 and the cavity ring 31, so that the entered water accumulates inside the cavity ring 31 and is filtered through the filter holes at the arc-shaped protrusion at the center of the arc-shaped filter disc 34. The filtered water enters the other side of the arc-shaped filter disc 34 and is introduced into the injection mechanism 2 through the connecting pipe 32 for spraying. A rotating cover 33 is rotatably installed at the annular cavity of the cavity ring 31, and an annular groove is provided on the outer side of the rotating cover 33 close to the connecting tube 4, and a sealing ring 37 is fixedly installed at the annular groove of the rotating cover 33.

[0019] A rotation groove is provided on the outer side of the rotating cover 33 away from the connecting tube 4, and a gasket 36 is rotatably installed at the rotation groove of the rotating cover 33. The rotating cover 33 is rotatably adapted to the inner wall of the cavity ring 31 through the gasket 36. Circular grooves are evenly provided on the outer side of the rotating cover 33, and connecting pipes 32 are fixedly installed at the circular grooves of the rotating cover 33. The inner wall of the connecting pipe 32 is fixedly connected to the outer side of the nozzle 208. When the injection mechanism 2 is connected to the flywheel, so that the flywheel drives the injection mechanism 2 to rotate, the injection mechanism 2 drives the connecting pipe 32, the rotating cover 33 and the arc filter disc 308 through the fixed connection between the connecting pipe 32 and the injection mechanism 2. 4 rotates, so that the arc filter disc 34 rotates on the inner wall of the cavity ring 31 while filtering, so that the water introduced at the fixed pipe 35 impacts the filtering position of the arc filter disc 34, so that the arc-shaped protrusion at the filtering position of the arc filter disc 34 guides the water flow when impacting, so that the water flow is guided to both sides when impacting the arc-shaped protrusion, so that the water flow drives the impurities at the filtering position to both sides, and cleans the filtering position of the arc filter disc 34. The inner wall of the rotating cover 33 is fixedly connected with the arc filter disc 34, and the center position of the outer side of the arc filter disc 34 is arc-shaped protruding toward the connecting tube 4 and filter holes are evenly opened.

[0020] When in use, the liquid storage mechanism 3 is fixedly connected to the diesel engine housing through the connecting tube 4, the injection mechanism 2 is fixedly connected to the flywheel, and the water pipe is connected to the connecting pipe 5. When the diesel engine is working, water is introduced into the liquid storage mechanism 3 through the connecting pipe 5, and then introduced into the injection mechanism 2 after being filtered by the liquid storage mechanism 3. Under the action of the introduced water pressure, it is sprayed out from the injection mechanism 2 and sprayed onto the surface of the flywheel. In coordination with the rotation of the flywheel, the water is evenly coated on the surface of the flywheel. During the rotation, the water on the surface is driven to move outward, and in coordination with the outer cover mechanism 1, the water is directed out while driving the air flow.

[0021] When water is introduced into the cavity ring 31 through the connecting pipe 5, after the water enters the cavity ring 31, it also enters the interior of the rotating cover 33. At the same time, the sealing ring 37 prevents the water from seeping out from between the rotating cover 33 and the cavity ring 31, so that the water entering is accumulated inside the cavity ring 31 and filtered through the filter holes at the arc-shaped protrusion at the center of the arc-shaped filter disc 34. The filtered water enters the other side of the arc-shaped filter disc 34 and is introduced into the injection mechanism 2 through the connecting pipe 32 for injection. At the same time, when the injection mechanism 2 is connected to the flywheel so that the flywheel drives the injection mechanism 2 to rotate, the connecting pipe 32 is connected to the injection mechanism 2. Through the fixed connection between the connecting pipe 32 and the injection mechanism 2, the injection mechanism 2 drives the connecting pipe 32, the rotating cover 33 and the arc-shaped filter disc 34 to rotate, so that the arc-shaped filter disc 34 rotates on the inner wall of the cavity ring 31 while filtering, so that the water introduced at the fixed pipe 35 impacts the filtering position of the arc-shaped filter disc 34, and the arc-shaped protrusion at the filtering position of the arc-shaped filter disc 34 guides the water flow during the impact, so that the water flow is guided to the inside and outside when impacting the arc-shaped protrusion, so that the water flow drives the impurities at the filtering position, drives the impurities to both sides, and cleans the filtering position of the arc-shaped filter disc 34.

[0022] In the spray mechanism 2, the fixed cylinder 201 is connected to the flywheel flange, so that the flywheel rotates and drives the fixed disk 204. During the rotation, the water introduced by the liquid storage mechanism 3 enters the interior of the nozzle 208, and the water pressure is transmitted to the spring 210 through the sliding disk 209. The water pressure compresses the spring 210 to deform, causing the sliding disk 209 to slide, opening the spray hole of the nozzle 208, so that water is sprayed out from the spray hole of the nozzle 208. During the water spraying process, the sprayed water mist is sprayed to the surface of the flywheel through the guidance and blocking of the outer cover disk 207. The heat of the wheel is transferred to the water in contact with the flywheel surface, thereby reducing the temperature of the flywheel. After the water mist contacts the flywheel surface, the centrifugal force of the flywheel rotation causes the water on the flywheel surface to move toward the outside of the flywheel, and cooperates with the scraper 203 to block the water, so that the water moves rapidly toward the outside along the scraper 203. When the water on the flywheel surface reaches a certain amount, it passes over the fixed ring 202 and continues to flow toward the outside along the gap between the support blocks 205. At the same time, during the rotation of the flywheel, when the amount of water attached to the flywheel surface through the groove ring 206 is large, the water is blocked from flowing toward the inside.

[0023] In the outer cover mechanism 1, the outer clamping block 13 is clamped on the arc surface of the outer side of the flywheel, and is fixedly connected to the fixed disk 204 through the outer ring disk 14. When the fixed disk 204 is driven by the rotation of the flywheel, the outer ring disk 14 is also driven to rotate. During the rotation of the outer ring disk 14, the air guide plate 15 is driven to rotate along the center position of the outer ring disk 14. During the rotation, the air inside the flywheel is driven to flow outward through the air guide plate 15, so that the air flowing outward brings the heat inside, and drives the water on the flywheel surface to flow outward, so that the air and the water thrown off the flywheel surface contact the inner wall of the outer arc cover 12, and the water and air are discharged through the through holes at the arc ring of the outer arc cover 12. During the process of air discharge, the inner air pressure is reduced, and the air on the outside is discharged through the gap between the outer clamping block 13 and the flywheel to enter the inner side of the flywheel.

[0024] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
