Description

Technical Field

[0001] This application relates to the technical field of marine electrical equipment, and specifically to a fault warning type cooling cycle control device for marine engines. Background Art

[0002] In a marine engine system, a cooling cycle control device is one of the key components to ensure the normal operation of the engine. During the operation of a marine engine, a large amount of heat is generated. If it is not cooled in a timely and effective manner, it will seriously affect the performance and lifespan of the engine, and may even lead to engine failure and shutdown, posing a major threat to the safe navigation of the ship.

[0003] The Chinese utility model patent with the publication number CN220786104U discloses a marine engine cooling device. By setting a follow-up pump, a water guide pipe, a filter screen, a drain pipe, a fixing cover, a heat conducting plate, heat dissipation fins, and a water outlet pipe, this device can have a good heat dissipation effect, facilitating the conduction of heat inside the engine, and enabling the dissipated heat to be volatilized and dissipated. However, this device only uses a single water guide pipe to convey cooling water into the system. Although a filter screen is set to filter impurities and dirt entering the cooling system, in actual operation, the filter screen is easily blocked due to the accumulation of impurities, resulting in a reduction in the water inflow. Once the filter screen becomes blocked or fails, the entire cooling cycle system will be affected, and even the system may shut down, affecting the normal navigation of the ship and possibly causing serious damage to the marine engine.

[0004] Therefore, this application provides a fault warning type cooling cycle control device for marine engines to solve the above problems. Summary of the Invention

[0005] This application provides a fault warning type cooling cycle control device for marine engines, aiming to solve the problems in the background art that in the existing marine engine cooling device, when impurities cause the filter screen in a single water guide pipe to become blocked, it is easy to affect the operation of the cooling system, and may even lead to system shutdown, threatening the normal navigation of the ship and the safety of the engine.

[0006] To achieve the above objective, this application provides the following technical solution: A fault warning type cooling cycle control device for marine engines includes a water pump, a cooler connected to the water pump and the marine engine, a water inlet pipe connected to the end of the water pump away from the cooler, and a filter screen fixedly installed in the water inlet of the water inlet pipe; The cooling cycle control device further includes a float assembly for rising and falling with the water level at a position above the filter screen in the water inlet pipe, a brush plate slidably arranged on the side of the filter screen close to the float assembly, and a transmission assembly arranged in the water inlet pipe and connected to the float assembly for sliding the brush plate; There are two water inlet pipes. A reversing assembly is arranged between the two water inlet pipes and the water pump and is connected to the floating ball assembly to enable the water pump to be respectively communicated with the two water inlet pipes. By providing a floating ball assembly that rises and falls with the water level, the system can, in real time, detect the water level change in the water inlet pipe, thereby indirectly determining whether the filter screen is blocked. This design realizes the automatic monitoring of the filter screen state, eliminating the need for regular manual inspections, improving the accuracy and timeliness of monitoring. At the same time, through the combined design of the transmission assembly and the brush plate, when the filter screen is blocked and the water level drops, the descent of the floating ball assembly will trigger the transmission assembly, causing the brush plate to slide on the filter screen, thus automatically cleaning the filter screen, reducing the frequency and difficulty of manual filter screen cleaning, and improving the maintenance efficiency and reliability of the system. In addition, through the connection components of the two water inlet pipes, the reversing assembly and the floating ball assembly, even if the filter screen of one of the water inlet pipes is blocked or fails, the reversing assembly will switch the water pump to communicate with the other water inlet pipe to ensure the continuity and reliability of the cooling circulation system, avoiding system shutdown caused by filter screen blockage and improving the operating safety of the ship's engine room.

[0007] Preferably, for the convenience of installation and use of the floating ball assembly, a chute is provided on one side of the water inlet pipe corresponding to the floating ball assembly. A partition is fixedly installed in the chute to divide the interior of the chute into a movable cavity and an installation cavity. The design of dividing the interior of the chute into a movable cavity and an installation cavity by the partition provides a clear installation position for the floating ball assembly, making the installation process more intuitive and simple.

[0008] Preferably, for the convenience of judging whether the filter screen is blocked, the floating ball assembly includes a guide rod fixedly installed in the movable cavity, a slider slidably sleeved on the guide rod and penetrating the movable cavity, and a floating ball arranged above the filter screen in the water inlet pipe and fixedly connected to the end of the slider away from the movable cavity. With this design, when the filter screen is blocked, the water flow is blocked and the water level drops, and the floating ball drops accordingly, so that it can be intuitively judged whether the filter screen is blocked without additional detection equipment or means. The design of the guide rod and the slider enables the floating ball to rise and fall stably with the water level.

[0009] Preferably, for the convenience of driving the transmission assembly, the floating ball assembly further includes a toothed plate fixedly arranged at the bottom end of the slider and located in the movable cavity. The toothed plate is connected to the transmission assembly.

[0010] Preferably, to facilitate the sliding of the brush plate, the transmission assembly includes a connecting shaft rotatably connected to the inner bottom end of the movable cavity and penetrating through the movable cavity and the installation cavity, a gear fixedly sleeved on the connecting shaft and located in the movable cavity for meshing with the toothed plate, a runner disposed in the installation cavity and fixedly connected to one end of the connecting shaft away from the gear, an eccentric shaft fixedly connected to a surface of the runner away from the connecting shaft, a connecting rod penetrating through the installation cavity and rotatably connected to the eccentric shaft, and a push rod fixedly connected to the brush plate and rotatably connected to one end of the connecting rod away from the eccentric shaft; through the meshing of the gear and the toothed plate, the movement of the floating ball is converted into the rotation of the runner, and then the brush plate is driven to slide on the filter screen through the eccentric shaft, the connecting rod and the push rod, so as to clean the filter screen.

[0011] Preferably, to ensure the sliding of the brush plate, guiding grooves for the brush plate to slide are formed at two side edges of the bottom of the filter screen corresponding to the brush plate; the design of the guiding grooves ensures the stability and accuracy of the brush plate during the sliding process, avoids the deviation and jamming of the brush plate, and improves the cleaning effect.

[0012] Preferably, to ensure the sealing of the movable cavity and protect the components in the movable cavity, two folding and telescopic sheets are provided on the outside of the movable cavity corresponding to the toothed plate and the gear, and two ends of the two folding and telescopic sheets are respectively fixedly connected to the top end of the slider and the top end of the movable cavity and the bottom end of the slider and the bottom end of the movable cavity; the design of the folding and telescopic sheets can expand and contract with the movement of the slider while not affecting the movement of the slider, so as to effectively seal the gap between the slider and the movable cavity, prevent seawater and impurities from entering the movable cavity, protect the components in the movable cavity from corrosion and damage, and improve the reliability of the system.

[0013] Preferably, to facilitate sucking seawater through the other water inlet pipe in time when one of the water inlet pipes is blocked, the commutation assembly includes a three-way commutation valve disposed between the two water inlet pipes and the water pump and a button fixedly disposed at the inner bottom end of the movable cavity for contacting the bottom end of the toothed plate to start the three-way commutation valve, and the water pump is respectively communicated with the two water inlet pipes through the three-way commutation valve; with such a design, when the filter screen of one of the water inlet pipes is blocked, the descent of the floating ball assembly will cause its toothed plate to trigger the button to start the three-way commutation valve, so that the water pump switches to connect with the other water inlet pipe. This design ensures the continuity and reliability of the cooling circulation system, avoids the shutdown of the system caused by the blockage of the filter screen, and improves the operating safety of the ship's engine room.

[0014] Preferably, in order to ensure the power for the toothed plate to slide and drive the gear to rotate, the cooling cycle control device further includes an electromagnetic control structure disposed in the slider and the movable cavity; the design of the electromagnetic control structure can further provide an additional lifting power to the slider through electromagnetic force to ensure that the toothed plate can drive the gear to rotate as the slider moves up and down, thereby further improving the driving efficiency and reliability of the transmission component and reducing energy loss and unnecessary power consumption.

[0015] Preferably, the electromagnetic control structure includes an electromagnetic sheet one respectively fixedly disposed at the top end inside the slider and the top end inside the movable cavity and magnetically attracting each other, an electromagnetic sheet two respectively fixedly disposed at the bottom end inside the slider and the bottom end inside the movable cavity and magnetically attracting each other, a switch one fixedly disposed at the top end of the inner wall of the movable cavity for contacting the top end of the slider to cut off the power supply of the electromagnetic sheet one and turn on the power supply of the electromagnetic sheet two, and a switch two fixedly disposed at the bottom end of the inner wall of the movable cavity for contacting the bottom end of the toothed plate to turn on the power supply of the electromagnetic sheet one and cut off the power supply of the electromagnetic sheet two; with such a design, when the slider moves up to the top end inside the movable cavity, the switch one is triggered, so that the electromagnetic sheet one at the top end of the slider and the top end inside the movable cavity is powered off, while the electromagnetic sheet two at the bottom end of the slider and the bottom end inside the movable cavity is powered on. When the filter screen is blocked, the slider descends, and the electromagnetic sheet two at its bottom end approaches the electromagnetic sheet two at the bottom end inside the movable cavity. Through magnetic attraction, the toothed plate can be quickly driven to move downward to make the toothed plate engage and drive with the gear. Conversely, the toothed plate can be quickly driven to rise to disengage the toothed plate from the gear engagement.

[0016] The ship's engine room fault warning type cooling cycle control device can indirectly judge whether the filter screen is blocked in real time through the water level change in the water inlet pipe by setting a floating ball assembly that rises and falls with the water level. This design realizes the automatic monitoring of the filter screen state, eliminates the need for manual regular inspection, improves the accuracy and timeliness of monitoring. At the same time, through the combined design of the transmission component and the brush plate, when the filter screen is blocked, the brush plate can slide on the filter screen, thereby automatically cleaning the filter screen, reducing the frequency and difficulty of manual cleaning of the filter screen, and improving the maintenance efficiency and reliability of the system; The ship's engine room fault warning type cooling cycle control device, through the connection components of the two water inlet pipes, the commutation component and the floating ball assembly, even if the filter screen of one of the water inlet pipes is blocked or fails, the commutation component will switch the water pump to communicate with the other water inlet pipe to ensure the continuity and reliability of the cooling cycle system, avoid system shutdown caused by filter screen blockage, and improve the operation safety of the ship's engine room; The ship's engine room fault warning type cooling cycle control device can further provide an additional lifting power to the slider through electromagnetic force by setting an electromagnetic control structure to ensure that the toothed plate can drive the gear to rotate as the slider moves up and down, thereby further improving the driving efficiency and reliability of the transmission component and reducing energy loss and unnecessary power consumption.

[0019] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0020] This embodiment provides a fault warning type cooling cycle control device for a ship's turbine engine, as Figures 1-6As shown in the figure, the cooling cycle control device includes a water pump 1, a cooler 2 connected to the water pump 1 and the ship's engine, a water inlet pipe 3 connected to the end of the water pump 1 away from the cooler 2, and a filter screen 4 fixedly installed in the water inlet of the water inlet pipe 3; the cooling cycle control device further includes a float assembly 5 arranged above the filter screen 4 in the water inlet pipe 3 for rising and falling with the water level, a brush plate 7 slidably arranged on the side of the filter screen 4 close to the float assembly 5, and a transmission assembly 8 arranged in the water inlet pipe 3 and connected to the float assembly 5 for sliding the brush plate 7; there are two water inlet pipes 3, and a reversing assembly 6 connected to the float assembly 5 is arranged between the two water inlet pipes 3 and the water pump 1 for connecting the water pump 1 to the two water inlet pipes 3 respectively.

[0021] During use, in the initial state, through the switching of the reversing assembly 6, the water pump 1 is connected to one of the water inlet pipes 3. When the water pump 1 is started, seawater will be sucked in through the water inlet pipe 3. The seawater entering the water inlet pipe 3 will also pass through the filtration of the filter screen 4, then flow through the cooler 2 and enter the water inlet pipe 3, and then flow into the ship's engine through the cooler 2. At this time, the cooling water absorbs the heat discharged from the ship's engine, and after the temperature rises, it is directly discharged into the seawater through the drain pipe. At the same time, the water pump 1 will continue to suck seawater through one of the water inlet pipes 3 and flow into the cooler 2 and then into the ship's engine to absorb heat to form a circulating cooling. However, when the filter screen 4 of one of the water inlet pipes 3 is blocked, at this time, the water level in the water inlet pipe 3 gradually decreases and drops. At this time, the float assembly 5 will also drop with the drop of the water level. As the float assembly 5 drops, the transmission assembly 8 will synchronously drive the brush plate 7 to reciprocate on the surface of the filter screen 4, so as to clean the surface of the filter screen 4. And when the float assembly 5 drops, it will trigger the reversing assembly 6, and the water pump 1 will be switched to be connected to the other water inlet pipe 3 through the reversing assembly 6 to suck seawater for cooling through the other water inlet pipe 3. After the filter screen 4 in this water inlet pipe 3 is blocked, similarly, the reversing assembly 6 will switch the water pump 1 to be connected to one of the water inlet pipes 3 to suck seawater for cooling.

[0022] Among them, in order to facilitate the installation and use of the float assembly 5, a sliding groove 31 is opened on one side of the water inlet pipe 3 corresponding to the float assembly 5, and a partition plate 32 for dividing the inside of the sliding groove 31 into a movable cavity 321 and an installation cavity 322 is fixedly installed in the sliding groove 31; the design of dividing the inside of the sliding groove 31 into a movable cavity 321 and an installation cavity 322 by the partition plate 32 in the sliding groove 31 provides a clear installation position for the float assembly 5, making the installation process more intuitive and simple.

[0023] Specifically, the float assembly 5 includes a guide rod 53 fixedly installed in the movable cavity 321, a slider 52 slidably sleeved on the guide rod 53 and penetrating through the movable cavity 321, and a float 51 arranged above the filter screen 4 in the water inlet pipe 3 and fixedly connected to the end of the slider 52 away from the movable cavity 321; When the water inlet pipe 3 in the water inlet pipe 3 is blocked, seawater cannot smoothly enter the water inlet pipe 3 through the filter screen 4. At this time, with the suction of the water pump 1, the water level in the water inlet pipe 3 will gradually drop. As the water level in the water inlet pipe 3 drops, at this time, the floating ball 51 will also drop synchronously and drive the slider 52 to slide down on the guide rod 53. Through the guidance of the slider 52 and the guide rod 53, the floating ball 51 can stably drop with the drop of the water level. On the contrary, when the filter screen 4 is not blocked, with the suction of the water pump 1, the water level in the water inlet pipe 3 will rise. At this time, the floating ball 51 will rise in the water inlet pipe 3 and also drive the slider 52 to slide up on the guide rod 53.

[0024] Furthermore, the floating ball assembly 5 further includes a toothed plate 54 fixedly arranged at the bottom end of the slider 52 and located in the movable cavity 321. The toothed plate 54 is connected to the transmission assembly 8. The transmission assembly 8 includes a connecting shaft 81 rotatably connected to the inner bottom end of the movable cavity 321 and passing through the movable cavity 321 and the installation cavity 322, a gear 82 fixedly sleeved on the connecting shaft 81 and located in the movable cavity 321 for meshing with the toothed plate 54, a runner 83 arranged in the installation cavity 322 and fixedly connected to one end of the connecting shaft 81 away from the gear 82, an eccentric shaft 84 fixedly connected to one side of the runner 83 away from the connecting shaft 81, a connecting rod 85 passing through the installation cavity 322 and rotatably connected to the eccentric shaft 84, and a push rod 86 fixedly connected to the brush plate 7 and rotatably connected to one end of the connecting rod 85 away from the eccentric shaft 84.

[0025] In addition, in order to ensure the sliding of the brush plate 7, the filter screen 4 is provided with guide grooves 41 for the brush plate 7 to slide at both sides of the bottom edge corresponding to the brush plate 7; the design of the guide grooves 41 ensures the stability and accuracy of the brush plate 7 during the sliding process, avoids the deviation and jamming of the brush plate 7, and improves the cleaning effect.

[0026] When the filter screen 4 is blocked and the water level in the water inlet pipe 3 drops, causing the float ball 51 to drive the slider 52 to descend on the guide rod 53, the toothed plate 54 connected to the slider 52 will also synchronously descend in the movable cavity 321. As the toothed plate 54 continues to descend, it will gradually engage with the gear 82. Then, as the toothed plate 54 continues to slide downward, the gear 82 will start to rotate under the push of the toothed plate 54. At this time, the rotation of the gear 82 is transmitted to the runner 83 through the connecting shaft 81, causing the runner 83 to rotate, and the rotation of the runner 83 will drive the eccentric shaft 84 to rotate. Since the eccentric shaft 84 is eccentrically arranged, the eccentric rotation of the eccentric shaft 84 will convert the reciprocating rotational motion into a linear reciprocating motion of the brush plate 7 connected to the push rod 86 through the connection of the connecting rod 85. As the brush plate 7 slides on the surface of the filter screen 4, the impurities on the surface of the filter screen 4 can be cleaned. When the filter screen 4 is not blocked and the water level in the water inlet pipe 3 rises, the float ball 51 will drive the slider 52 to slide on the guide rod 53. At this time, as the slider 52 slides, the toothed plate 54 will gradually rise and disengage from the engagement with the gear 82.

[0027] It can be understood that in order to ensure the sealing of the movable cavity 321 and protect the components in the movable cavity 321, two folding telescopic sheets 3211 are provided on the outer sides of the toothed plate 54 and the gear 82 corresponding to the movable cavity 321. The two ends of the two folding telescopic sheets 3211 are respectively fixedly connected to the top of the slider 52 and the top of the movable cavity 321 and the bottom of the slider 52 and the bottom of the movable cavity 321; the design of the folding telescopic sheet 3211 can, while not affecting the movement of the slider 52, also expand and contract with the movement of the slider 52 to effectively seal the gap between the slider 52 and the movable cavity 321, preventing seawater and impurities from entering the movable cavity 321 and protecting the components in the movable cavity 321 from corrosion and damage, thereby improving the reliability of the system.

[0028] It should be noted that the folding telescopic sheet 3211 can be made of elastic plastic material.

[0029] Furthermore, the commutation component 6 includes a three-way commutation valve 61 provided between the two water inlet pipes 3 and the water pump 1 and a button 62 fixedly arranged at the inner bottom end of the movable cavity 321 for contacting the bottom end of the toothed plate 54 to start the three-way commutation valve 61. The water pump 1 is respectively communicated with the two water inlet pipes 3 through the three-way commutation valve 61.

[0030] Under normal circumstances, the water pump 1 selects one of the water inlet pipes 3 as the water inlet channel through the three-way reversing valve 61, and sends the cooling water into the cooler 2 for circulating cooling. When the filter screen 4 is blocked, the water level in the water inlet pipe 3 drops, and the float ball 51 drops accordingly, driving the slider 52 and the toothed plate 54 to slide downward along the guide rod 53. At this time, the toothed plate 54 connected to the slider 52 will contact the button 62 and trigger the button 62 to start the three-way reversing valve 61. After receiving the signal, the three-way reversing valve 61 switches its working state, switching the water inlet channel of the water pump 1 from the blocked water inlet pipe 3 to the other unblocked water inlet pipe 3. After switching the water inlet pipe 3, the water pump 1 sucks the cooling water from the other unblocked water inlet pipe 3 and continues the cooling cycle. Moreover, the button 62 of the three-way reversing valve 61 can be connected to the input end of the ship's control system, and the three-way reversing valve 61 is connected to the output end of the ship's control system for starting the three-way reversing valve 61.

[0031] Furthermore, the cooling cycle control device further includes an electromagnetic control structure 9 arranged in the slider 52 and the movable cavity 321. The electromagnetic control structure 9 includes an electromagnetic sheet one 91 respectively fixed at the inner top end of the slider 52 and the inner top end of the movable cavity 321 and magnetically attracting each other, an electromagnetic sheet two 92 respectively fixed at the inner bottom end of the slider 52 and the inner bottom end of the movable cavity 321 and magnetically attracting each other, a switch one 93 fixed at the inner wall top end of the movable cavity 321 for contacting the top end of the slider 52 to cut off the power supply of the electromagnetic sheet one 91 and turn on the power supply of the electromagnetic sheet two 92, and a switch two 94 fixed at the inner wall bottom end of the movable cavity 321 for contacting the bottom end of the toothed plate 54 to turn on the power supply of the electromagnetic sheet one 91 and cut off the power supply of the electromagnetic sheet two 92; When the filter screen 4 is blocked and the water level in the water inlet pipe 3 drops, causing the float ball 51 to drive the slider 52 to descend along the guide rod 53, the toothed plate 54 connected to the slider 52 will also synchronously descend within the movable cavity 321. As the slider 52 continues to descend, the electromagnetic plate two 92 at the bottom end thereof will approach the electromagnetic plate two 92 at the inner bottom end of the movable cavity 321. Under the magnetic attraction of the two electromagnetic plates two 92, it will further drive the slider 52 to descend, so that the slider 52 can have sufficient power to drive the toothed plate 54 to continuously descend and gradually engage with the gear 82, thereby driving the toothed plate 54 to rotate to achieve the movement of the brush plate 7. Moreover, when the toothed plate 54 descends to the inner bottom end of the movable cavity 321, it will contact the switch two 94, triggering the switch two 94 to start. At this time, the electromagnetic plate two 92 in the slider 52 and the movable cavity 321 will be powered off, while the electromagnetic plate one 91 in the slider 52 and the movable cavity 321 will be powered on, so that when the filter screen 4 is not blocked, the float ball 51 can drive the slider 52 to move upward without being magnetically attracted by the two electromagnetic plates two 92. When the filter screen 4 is not blocked and the water level in the water inlet pipe 3 rises, the float ball 51 will drive the slider 52 to slide along the guide rod 53. At this time, as the slider 52 slides, the electromagnetic plate one 91 at its top end will gradually approach the electromagnetic plate one 91 at the inner top end of the movable cavity 321. Similarly, under the magnetic attraction of the two electromagnetic plates one 91, it will further drive the slider 52 to rise, enabling the slider 52 to have sufficient power to drive the toothed plate 54 to rise, causing the toothed plate 54 to gradually disengage from the gear 82. Moreover, when the slider 52 moves to the inner top end of the movable cavity 321, it will contact the switch one 93, triggering the switch one 93 to start. At this time, the electromagnetic plate one 91 in the slider 52 and the movable cavity 321 will be powered off, while the electromagnetic plate two 92 in the slider 52 and the movable cavity 321 will be powered on, so as to provide additional downward power for the slider 52 when the filter screen 4 is blocked. Among them, the button 62 of the three-way reversing valve 61 can be connected to the input end of the control system of the ship, and both the switch one 93 and the switch two 94 are connected to the control system of the ship for power-on and power-off of the electromagnetic plate one 91 and the electromagnetic plate two 92.

[0032] As described above, the above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application, according to the technical solution and its concept of the present application, makes equivalent substitutions or changes, and should be covered by the protection scope of the present application.
