Description

Technical Field

[0001] This invention pertains to marine engine technology, and particularly relates to a marine engine with a cooling and heat dissipation protection device. Background Technology

[0002] Marine machinery is the collective term for all the machinery, equipment, and systems installed to meet the needs of ship navigation, various operations, personnel living conditions, and the safety of people and property. Marine machinery is also the ship's power plant. Its normal, stable, and reliable operation is crucial for ensuring the safe navigation of ships in various sea conditions and environments. Once marine machinery malfunctions or fails, it not only poses a serious threat to the safety of the ship but may also affect its economic efficiency and environmental performance. Therefore, protecting marine machinery during navigation is extremely important.

[0003] The existing Chinese utility model application document with announcement number CN214451778U discloses a marine engine with a protective device, "including a first horizontal plate and a marine engine body. The marine engine body is installed in a groove of the first horizontal plate, and the lower outer wall of the marine engine body is clearance-fitted with the inner wall of the groove of the first horizontal plate. A protective device is installed on the top of the marine engine body. The protective device includes a second horizontal plate, a vertical rod, a first spring, a first connecting rod, a second connecting rod, a third horizontal plate, and a trapezoidal plate. The lower surfaces of the left and right second horizontal plates are fixedly connected to the marine engine body. A vertical rod is fixedly connected to the middle of the upper surface of the second horizontal plate. A first spring is installed on the outer wall of the vertical rod. The left and right sides of the front end face of the second horizontal plate are rotatably connected to the first connecting rod through a rotating shaft. The top of the first connecting rod is connected to a rotating shaft." A second connecting rod is rotatably connected to the shaft, and a third horizontal plate is rotatably connected above the second connecting rod via a rotating shaft. A trapezoidal plate is fixed to the upper surface of the third horizontal plate, and the outer wall of the vertical rod is clearance-fitted with the inner wall of the through hole in the third horizontal plate and the trapezoidal plate, respectively. Although this ship's engine solves the problem of lack of protective structure after the engine equipment is subjected to external forces through the first and second springs, most ship main engine power units use internal combustion engines such as diesel engines, which generate a lot of heat during operation. The heat dissipates slowly, and long-term accumulation can cause the main engine temperature to become too high, also affecting the normal operation of the engine. Furthermore, this ship's engine alone cannot effectively purify the exhaust gases produced by the combustion of the ship's engine. If these exhaust gases are directly discharged into the atmosphere, it will not only cause air pollution to the environment but also have a negative impact on human health. Summary of the Invention

[0004] To address the problems existing in the prior art, the present invention aims to provide a marine engine with a cooling and heat dissipation protection device. This device uses a cooling component to spray water to cool and protect the engine body, and a brush plate to clean the surface of the engine body. The heat dissipation component increases the heat dissipation area with heat dissipation fins, and a fan accelerates heat dissipation. A purification component purifies the exhaust gas generated by the engine body before discharge, thereby reducing air pollution. Simultaneously, the design of the buffer component, including guide rods and springs, improves the buffering effect when the engine body is subjected to external forces, effectively protecting the engine.

[0026] As described above, the present invention has the following beneficial effects:

[0027] (1) A ship engine with a cooling and heat dissipation protection device according to the present invention has a connecting frame fixedly connected to a connecting plate on both sides. When the motor drives the threaded rod to rotate, the connecting frame and the connecting plate move synchronously. The nozzle sprays water evenly, so that the water comes into full contact with different positions on the side wall of the ship engine body, thereby achieving cooling and protection.

[0028] (2) A ship engine with a cooling and heat dissipation protection device of the present invention, wherein when the connecting frame moves, one side of the brush plate overlaps with the ship engine body to brush off the dust on the surface of the ship engine body, thereby cleaning the surface of the ship engine body.

[0029] (3) A ship engine with a cooling and heat dissipation protection device of the present invention has a heat-conducting sleeve one and a heat-conducting sleeve two installed at the upper and lower ends of the heat dissipation fins, respectively. The heat dissipation fins are fixedly connected to one side of the ship engine body, which can increase the heat dissipation area on one side of the ship engine body.

[0030] (4) In the present invention, a ship engine with a cooling and heat dissipation protection device, the air blown out from one side of the fan directly contacts the heat dissipation fins, which can accelerate the evaporation of heat on the surface of the heat dissipation fins, improve the heat dissipation intensity of the ship engine body, avoid the accumulation of heat inside the ship engine body, and improve the protection effect on the ship engine body.

[0031] (5) In a marine engine with a cooling and heat dissipation protection device, the first adsorption plate and the second adsorption plate are fixedly connected in the purification box. One end of the purification pipe passes through the purification box. The exhaust gas generated by the operation of the marine engine flows in the purification pipe and is concentrated and discharged into the purification box. The gas moves upward, is filtered by the filter plate, is sprayed and neutralized by the spray pipe, and is then adsorbed and treated by the first adsorption plate and the second adsorption plate to achieve the purification of the exhaust gas and reduce the pollution of the air caused by the direct discharge of exhaust gas.

[0032] (6) A ship engine with a cooling and heat dissipation protection device of the present invention has a telescopic guide rod and a spring between the reinforcing plate and the buffer plate, which can guide the lifting and lowering of the buffer plate and improve the buffering effect of the buffer plate on the top of the reinforcing plate after being subjected to force.

[0045] In the description of this invention, it should be noted that the positional relationships indicated by terms such as "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" are based on the positional relationships shown in the accompanying drawings and are only for the purpose of facilitating the description of the embodiments of this invention and simplifying the description. They are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific direction, and therefore should not be construed as a limitation of this invention.

[0046] Example 1

[0047] This embodiment provides a ship engine with a cooling and heat dissipation protection device, including a ship engine body 8, a support frame, a cooling component 5, and a heat dissipation component. The cooling component 5 cools the ship engine body 8 by spraying water and cleaning, and the heat dissipation component dissipates heat from the ship engine body 8 by heat transfer and blowing air.

[0048] like Figure 2 and Figure 7 As shown, the support frame is assembled from a hollow frame 32, a support base 3, a pair of auxiliary plates 4, and side plates 33. The ship's engine body 8 is detachably installed within the hollow frame 32, facilitating its installation at the upper limit of the support frame. The support base 3 is located at the bottom of the hollow frame 32, providing support for the bottom of the ship's engine body 8. The side plates 33 are engaged with the upper surface of the support base 3 and located on the back of the ship's engine body 8. The bottom end of the auxiliary plates 4 is engaged with the upper surface of the support base 3, facilitating their installation and removal on the support base 3. A pair of auxiliary plates 4 are located on the left and right sides of the ship's engine body 8, respectively, and opposite to its sides. A driving component is fixedly connected to the inner end face of each auxiliary plate 4. The auxiliary plate 4 is movably connected to the cooling assembly 5 via the driving component, which drives the cooling assembly 5 to move horizontally along the front-rear direction of the auxiliary plate 4. Figures 5-7 As shown, the top end face of the hollow frame 32 is also provided with a wedge-shaped guide plate 31. The guide plate 31 fits against the side of the ship engine body 8, so that the cooling water sprayed by the cooling component 5 is guided to the outside of the hollow frame 32.

[0049] like Figures 2-4As shown, the cooling component 5 is located between the ship's engine body 8 and the auxiliary plate 4. The cooling component 5 includes a connecting frame 52, a brush plate 51, and a water supply device. The inner side of the connecting frame 52 is fixedly connected to the brush plate 51. The side of the brush plate 51 closest to the ship's engine body 8 is the brush surface, which is provided with soft bristles. The bristles are in contact with the side wall of the ship's engine body 8. When the brush plate 51 moves, it can clean the surface of the ship's engine body 8 and reduce the residue of dirt on the ship's engine body 8. A hollow connecting plate 55 is provided at each of the front and rear ends of the connecting frame 52. The connecting plate 55 is connected by a crossbar. Fixedly connected to the connecting frame 52, the connecting plate 55 is equipped with several nozzles 56. The nozzles 56 are connected to the water supply device through stainless steel rigid water pipes 57, enabling the overall movement of the cooling component 5 and ensuring the supply of cooling water. The distance between the connecting plates 55 is greater than the width of the brush plate 51. The two connecting plates 55 are located on both sides of the brush plate 51, and the nozzles 56 face the side wall of the ship's engine body 8. The cooling component 5 sprays water to cool the side wall of the ship's engine body 8 through the nozzles 56. At the same time, the brush plate 51 can be used to clean the side wall of the ship's engine body 8. The outer side of the connecting frame 52 is equipped with a connecting block 58, and a transmission rod is sleeved inside the connecting block 58. The transmission rod is connected to the driving component, so that the driving component drives the connecting frame 52 to slide back and forth along the auxiliary plate 4 through the transmission rod.

[0050] like Figure 3 As shown, in this embodiment, the transmission rod is a threaded rod 43, and the connecting block 58 has a thread corresponding to the threaded rod 43. The threaded rod 43 is sleeved on the connecting block 58. The driving component is a motor 42, which is fixed to the inner end face of the auxiliary plate 4. The motor 42 is located near the edge of the end face of the auxiliary plate 4. The auxiliary plate 4 can provide support for the installation of the motor 42 and improve the stability of the motor 42 during use. One end of the output shaft of the motor 42 is threadedly connected to the connecting block 58 through the threaded rod 43. The motor 42 drives the threaded rod 43 to rotate, thereby moving the connecting block 58 and realizing the reciprocating movement of the cooling component 5 on the inner end face of the auxiliary plate 4.

[0051] like Figures 2-4 As shown, the water supply device includes a water tank 53 and a water pump 54. One end of the water pump 54 is connected to the nozzle 56 via a water pipe 57, and the other end of the water pump 54 is detachably connected to the top of the water tank 53. A slider 91 is provided on the outer side of the water tank 53, and a guide groove 92 corresponding to the slider 91 is provided on the inner side of the auxiliary plate 4 to ensure that the slider 91 can slide within the guide groove 92. The water tank 53 is slidably connected to the auxiliary plate 4; simultaneously, as Figure 2 and Figure 10As shown, a limiting strip 41 is also fixedly connected to the inner end face of the auxiliary plate 4. The height of the limiting strip 41 corresponds to that of the connecting block 58. The connecting block 58 is slidably connected within the limiting strip 41, providing guidance for the movement of the connecting block 58. When the motor 42, acting as a driving component, drives the connecting frame 52 to move via threads, the connecting block 58 can slide smoothly back and forth within the limiting strip 41. Simultaneously, the water tank 53 can slide smoothly back and forth within the guide groove 92, ensuring the smooth movement of the cooling component 5.

[0052] like Figure 1 As shown, a second fan 7 is also fixedly installed on the inner side of the auxiliary plate 4. The second fan 7 is located at the edge of the end face of the auxiliary plate 4 and close to the front of the ship engine body 8. In this embodiment, the second fan 7 overlaps with one end face of the limiting strip 41.

[0053] In practical operation, the ship's engine body 8 is electrically connected to a terminal control device, and the cooling component 5 is also electrically connected to the terminal control device. While controlling the normal operation of the ship's engine body 8 through the terminal control device, the water pump 54 in the cooling component 5 is controlled to provide intermittent water supply to assist the brush plate 51 in cleaning. This enables the cooling component 5 to perform an intermittent cleaning process of spraying, brushing, and then spraying on the ship's engine body 8, thus rinsing away the dirt removed by the brush plate 51. While ensuring that the cooling water sprayed from the nozzle 56 cools the ship's engine body 8, the cleaning effect of the cooling component 5 on the side walls of the ship's engine body 8 is improved. The water supply interval of the water pump 54 can be adjusted by adjusting the terminal control device, thereby adjusting the cleaning interval. During the cleaning process and between cleaning intervals, the second fan 7 on the auxiliary plates 4 on both sides of the ship's engine body 8 can be used to continuously blow air onto the side walls of the ship's engine body 8.

[0054] like Figure 6 and Figure 7 As shown, the heat dissipation assembly is located between the ship's engine body 8 and the side plate 33. The heat dissipation assembly includes heat dissipation fins 34, a first heat-conducting sleeve 35, and a second heat-conducting sleeve 37. The first heat-conducting sleeve 35 and the second heat-conducting sleeve 37 are symmetrically arranged on the inner end face of the side plate 33. The first heat-conducting sleeve 35 is fixedly connected to the upper part of the inner end face of the side plate 33, and the second heat-conducting sleeve 37 is fixedly connected to the lower part of the inner end face of the side plate 33. The openings of the first heat-conducting sleeve 35 and the second heat-conducting sleeve 37 are opposite each other. The two ends of the heat dissipation fins 34 are fixedly connected to the first heat-conducting sleeve 35 and the second heat-conducting sleeve 37 respectively to ensure the stable installation of the heat dissipation fins 34 on the side plate 33. The heat dissipation fins 34 are composed of a set of heat dissipation fins, which are evenly distributed between the first heat-conducting sleeve 35 and the second heat-conducting sleeve 37.

[0055] A fan 36 is also fixedly installed on the outer end face of the side plate 33. The side plate 33 has an air outlet at the corresponding installation position of the fan 36, so that the fan 36 can provide auxiliary heat dissipation for the heat dissipation components through the air outlet. One side of the heat dissipation fin 34 overlaps with the back of the ship engine body 8, and the other side of the heat dissipation fin 34 is close to the side plate 33, and there is a gap between it and the inner end face of the side plate 33, so that the air blown out by the fan 36 can flow quickly and accelerate the heat dissipation on the heat dissipation fin 34.

[0056] Example 2

[0057] This embodiment provides a marine engine with a cooling and heat dissipation protection device. Based on embodiment 1, the marine engine further includes a guide plate 2 for limiting the marine engine body 8 and a purification component 1 for treating the exhaust gas generated by the marine engine body 8.

[0058] like Figure 1 , Figure 2 and Figure 8 As shown, the guide plate 2 engages with the upper surface of the support base 3, and a collar 22 is fixedly installed on the inner end face of the guide plate 2. The collar 22 consists of a pair of mutually engaging semicircular rings. The guide plate 2 includes a left guide plate 2 and a right guide plate 2, and the two semicircular rings of the collar 22 are fixedly connected to the left guide plate 2 and the right guide plate 2, respectively.

[0059] The upper surface of the support base 3 is provided with a sliding positioning groove 93. The left guide plate 2 and the right guide plate 2 can slide and engage with each other along the sliding positioning groove 93, and drive the semi-circular ring to form a collar 22, so that the collar 22 is sleeved on the annular protrusion on the front of the ship engine body 8, thereby realizing the limiting and fixing of the ship engine body 8.

[0060] like Figure 2 As shown, the guide plate 2 is also provided with a telescopic limiting rod 21. One end of the limiting rod 21 is vertically fixed to the guide plate 2, and the other end of the limiting rod 21 is adjusted to abut against the front end face of the ship engine body 8, so that the limiting rod 21 overlaps with the front face of the ship engine body 8, thereby generating a lateral supporting force between the ship engine body 8 and the guide plate 2, so that the bottom of the guide plate 2 is tightly fitted with the inner wall of the sliding positioning groove 93 on the support seat 3, thereby reducing the movement of the guide plate 2 in the sliding positioning groove 93 and realizing the limiting and fixing of the installation position of the guide plate 2.

[0061] like Figure 1 and Figure 2As shown, the purification component 1 is fixedly installed on the end face of the front of the ship's engine body 8, which is conducive to the stable use of the purification box 16. The purification component 1 includes the purification box 16 and the collection cylinder 11. The top of the collection cylinder 11 is provided with an opening, and the bottom of the collection cylinder 11 is fixedly connected to the top of the purification box 16, so that the purified gas can be discharged from the opening of the collection cylinder 11.

[0062] like Figure 3 , Figure 8 and Figure 9 As shown, the purification chamber 16 is fixedly connected from bottom to top with a drain pipe 18, a purification pipe 17, a filter plate 14, a spray pipe 12, an adsorption plate one 13, and an adsorption plate two 15. The drain pipe 18 is connected to the bottom of the purification chamber 16. The spray pipe 12 has several spray holes facing downwards. The inlet pipe of the spray pipe 12 passes through the side wall of the purification chamber 16 and is connected to an external container containing spray liquid. One end of the purification pipe 17 passes through the side wall of the purification chamber 16 and enters the interior of the purification chamber 16. The other end of the purification pipe 17 is located above the ship's engine body 8, so that the exhaust gas generated by the ship's engine body 8 can be collected by the purification pipe 17 and enter the purification chamber 16. Then the gas moves upward and passes through the filter plate 14, the spray pipe 12, and the adsorption plates 13 and 15 in sequence before being discharged from the upper opening of the collection cylinder 11. The gas treated by the purification assembly 1 can reduce the acidic harmful substances and odors inside, and reduce the interference to the environment. In actual operation, the sprayed droplets are in an atomized state. The pores on the filter plate 14 are relatively large, which can filter impurities with larger diameters. Therefore, the downward spraying process will not affect the filter plate 14. The sprayed liquid can be discharged through the drain pipe 18 located at the bottom of the purification box 16.

[0066] like Figure 5 and Figure 6As shown, the reinforcing plate 64 is snapped onto the top of the ship's engine body 8, and the reinforcing plate 64 and the top of the ship's engine body 8 form a cavity. A retractable guide rod 61 and a spring 65 are provided between the upper end face of the reinforcing plate 64 and the lower end face of the buffer plate 6. In this embodiment, the springs 65 are evenly distributed on the upper end face of the reinforcing plate 64, and the two ends of the springs 65 are respectively fixedly connected to the upper end face of the reinforcing plate 64 and the lower end face of the buffer plate 6. A guide rod 61 is provided at each of the four corners of the upper end face of the reinforcing plate 64, and the two ends of the guide rod 61 are respectively fixedly connected to the upper end face of the reinforcing plate 64 and the lower end face of the buffer plate 6. This guide rod can guide the lifting and lowering of the buffer plate 6 and improve the buffering effect of the buffer plate 6 on the top of the reinforcing plate 64 after being subjected to force.

[0067] like Figure 2 and Figure 6 As shown, a guide wheel 63 is provided between the inner side of the buffer plate 6 and the surface of the ship engine body 8. The edge of the buffer plate 6 is movably connected to the upper end face of the extension plate 44 through a support rod 62. The support rod 62 consists of a pair of hinged connecting rods. One end of the support rod 62 is hinged to the edge of the buffer plate 6, and the other end of the support rod 62 is hinged to the upper end face of the extension plate 44, which can provide buffer protection for the bottom of the buffer plate 6.

[0068] Example 4

[0069] This embodiment provides a method for using a ship engine with a cooling and heat dissipation protection device, as described in Embodiment 3, and the working principle for achieving its function.

[0070] Installation method: First, install the ship engine body 8 inside the hollow frame 32. Engage the guide plate 31 at the top of the hollow frame 32, with one side of the guide plate 31 overlapping the ship engine body 8 to limit its movement. Engage the side plate 33 at the top of the support base 3. At this point, one side of the heat-conducting sleeve 35 overlaps with the guide plate 31, and one side of the heat dissipation fins 34 is flush with the side wall of the ship engine body 8. Engage the auxiliary plate 4 at the top of the support base 3, with one side of the brush plate 51 overlapping the side wall of the ship engine body 8. Engage the extension plate 44... At the top of the auxiliary plate 4, the reinforcing plate 64 is engaged in the gap at the top of the ship's engine body 8 to install the guide rod 61; at this time, the bottom of the support rod 62 is engaged with the extension plate 44, and the guide plate 2 is engaged on the support seat 3. The left guide plate 1 and the right guide plate 1 are moved respectively to engage the collar 22 with one side of the ship's engine body 8. The limiting rod 21 is a telescopic structure in which the inner rod and the outer rod are connected by threads. By rotating the inner rod of the limiting rod 21, the end of the inner rod overlaps with the side wall of the ship's engine body 8 to protect the entire ship's engine body 8.

[0071] The buffer protection function is implemented as follows: The guide rod 61 is a telescopic structure with an inner rod and an outer rod sleeved together. When the ship's engine body 8 is impacted by an external force, the spring 65 is compressed, and the guide rod 61 extends and retracts. The bottom of the guide rod 61 is connected to the reinforcing plate 64, which buffers the bottom of the guide rod 61 and reduces the impact on the reinforcing plate 64, thereby reducing the force on the top of the ship's engine body 8 and protecting the ship's engine body 8. When the guide rod 61 moves down, one side of the guide wheel 63 contacts the side wall of the ship's engine body 8, and the guide wheel 63 rotates on the ship's engine body 8. The support rod 62 is composed of two hinged support rods and a connector. One end of the support rod is sleeved in the connector and can be rotatably connected. When the guide rod 61 moves down, the opening angle between the two support rods changes, and the bottom of the support rod 62 slides in the extension plate 44, which can support the bottom of the guide rod 61.

[0072] The cooling function is achieved as follows: When the ship's engine body 8 is in use, the motor 42 drives the threaded rod 43 to rotate, and the connecting block 58 moves on the threaded rod 43. The terminal control device controls the water pump 54 to work. The water pump 54 sends the water inside the water tank 53 into the connecting plate 55 through the water pipe 57, and sprays it out through the nozzle 56 to spray and cool the side wall of the ship's engine body 8. The brush plate 51 moves with the connecting frame 52 and can clean the side wall of the ship's engine body 8.

[0073] The heat dissipation function is achieved as follows: the fan 7 on one side of the auxiliary plate 4 can accelerate the evaporation of moisture on the side wall of the ship engine body 8, thereby accelerating the heat dissipation of the ship engine body 8. The sprayed water can be guided by the guide plate 31 and discharged from the top of the support base 3. The guide plate 31 is made of thermally conductive material. Through the overlap between the guide plate 31 and the thermally conductive sleeve 35, the thermally conductive sleeve 35 and the heat dissipation fins 34 can be cooled down. The fan 36 has an air outlet on the side near the side plate 33. The air outlet penetrates the side plate 33 and can accelerate the evaporation of heat from the surface of the heat dissipation fins 34 and the thermally conductive sleeve 37, thereby improving the heat dissipation intensity of the ship engine body 8.

[0074] The purification function is achieved as follows: the exhaust gas generated by the ship's engine 8 enters the purification box 16 through the purification pipe 17, and after being filtered by the filter plate 14 to remove dust, it continues to rise. The spray pipe 12 is connected to an alkaline solution to spray the exhaust gas and neutralize the acidic gases in the exhaust gas. The adsorption plate 2 15 is equipped with activated carbon particles, and the adsorption plate 1 13 is a high-polymer waterproof and breathable membrane. After the exhaust gas is adsorbed by the adsorption plate 2 15, it is treated again by the adsorption plate 1 13, and then discharged through the collection cylinder 11.
