Description

Technical Field

[0001] This utility model specifically relates to an electrical automation control device for marine engineering, belonging to the field of electrical automation technology. Background Technology

[0002] Naval architecture and ocean engineering, as a comprehensive engineering discipline, plays an extremely important role in today's society. It covers a series of complex fields, from ship design and construction to the development and utilization of marine resources, involving knowledge from multiple disciplines such as mechanics, electronics, materials, and fluid mechanics. With the advancement of global economic integration and the continuous deepening of the exploration of marine resources, the importance of naval architecture and ocean engineering has become increasingly prominent, and its development level has become one of the important indicators for measuring a country's comprehensive strength.

[0003] Among the many components of shipbuilding and marine engineering, electrical automation control devices occupy a central position. They are like the "brain" and "nervous system" of a ship, responsible for the precise control and coordinated operation of various electrical equipment. From the control of propulsion motors in the ship's power system to ensure that the ship travels at a predetermined speed and course, to the power distribution system to rationally allocate electrical energy to various electrical units on the ship, such as lighting, ventilation, and communication systems, to the automated monitoring and regulation of various mechanical equipment to ensure stable operation of the equipment, to the collection of ship operating status data through sensors and the intelligent analysis and decision-making based on preset programs, thereby achieving efficient and safe navigation of the ship.

[0004] However, when ships sail in the vast ocean, the continuous impact of waves and the strong winds cause frequent rocking and turbulence. Under such dynamic interference, the internal electrical components are prone to loosening of connections and detachment of solder joints due to long-term vibration and impact, which can lead to poor circuit contact, signal transmission interruption, and paralysis of the entire control device. Although some existing electrical automation control devices have vibration damping structures, most common damping mechanisms can only dampen vibrations in a single vertical or lateral direction and cannot flexibly dampen vibrations according to the actual swaying direction of the ship. Therefore, this application provides an electrical automation control device for marine engineering. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an electrical automation control device for marine engineering, which effectively buffers the vibrations caused by ship rolling and maintains the internal temperature of the control device.

[0006] To further achieve the above objectives, the following technical solution is adopted: An electrical automation control device for marine engineering includes a base and a control device body. The base is installed on the hull surface. A sealed door is provided on one side of the control device body. Multiple support frames are fixedly connected inside the control device body. An air inlet is fixedly connected to the top of one side of the base, and an air outlet is fixedly connected to the bottom of one side of the base. The air inlet and air outlet are diagonally distributed. Buffer mechanisms are provided at both the top and bottom ends of the control device body. Air guide slots are opened at both ends of the multiple support frames. Filter mechanisms are installed inside the air inlet and air outlet, and a heat dissipation mechanism is installed inside the air outlet.

[0007] Preferably, the buffer mechanism includes two support blocks fixedly connected to the top of the control device body and the outer wall of the base.

An elastic damper is provided inside the sleeve. The two ends of the elastic damper are fixedly connected to one end of each of the two connecting blocks. A damping spring is fitted on the outer wall of the elastic damper. The two ends of the damping spring are fixedly connected to one end of each of the two connecting blocks.

[0008] Preferably, guide blocks are fixedly connected to both sides of the sleeve, and a sliding groove is opened inside each of the two guide blocks. A guide rod is fixedly connected to each of the two sliding grooves. A slider is slidably connected to the outer wall of each of the two guide rods. An adjusting rod is symmetrically rotatably connected to both sides of each of the two sliders. The ends of the multiple adjusting rods away from the sliders are rotatably connected to one side of each of the two support blocks.

[0009] Preferably, the outer walls of both guide rods are fitted with damping springs, and the two ends of the damping springs are fixedly connected to the inner wall of the slider and the inner wall of the groove, respectively. The top surfaces of the multiple support frames are fixedly connected with buffer damping pads.

[0010] Preferably, the heat dissipation mechanism includes multiple cooling fans fixedly connected inside the air outlet duct, a temperature sensor is fixedly connected to one side of the control device body, the temperature sensor and multiple cooling fans are electrically connected to an external controller, and waterproof and breathable valves are fixedly connected inside both the air inlet duct and the air outlet duct.

[0014] Beneficial effects: 1. This application includes a buffer mechanism. The vibration generated by the ship's rocking is transmitted to multiple buffer mechanisms through the base. By setting multiple buffer mechanisms, it can cope with the complex swaying directions during the ship's navigation, rather than being limited to vibration reduction in a single direction. This effectively resists the ship's rocking and turbulence, thus ensuring the stability of the internal electrical components of the device, reducing problems such as loose connections and solder joint detachment caused by vibration, improving the reliability of the equipment operation, and providing a strong guarantee for the safe navigation of the ship.

[0015] 2. This application includes a heat dissipation mechanism. As the cooling fan rotates, a negative pressure is gradually generated, which guides the outside cold air from the air inlet duct into the control device body. Through the guidance of multiple air guide slots, the cold air can be evenly dispersed and flow through the various electronic components inside the control device body, so as to evenly dissipate heat from the electronic components. Then, the hot air is discharged to the outside through the air outlet duct by the operation of multiple cooling fans, thereby achieving rapid heat dissipation. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5 As shown, an electrical automation control device for marine engineering includes a base 1 and a control device body 2. The base 1 is installed on the surface of the hull. A sealing door 3 is provided on one side of the control device body 2. Multiple support frames 4 are fixedly connected inside the control device body 2. An air inlet duct 5 is fixedly connected to the top of one side of the base 1, and an air outlet duct 6 is fixedly connected to the bottom of one side of the base 1. The air inlet duct 5 and the air outlet duct 6 are diagonally distributed. Buffer mechanisms are provided at both the upper and lower ends of the control device body 2. Air guide slots 7 are opened at both ends of the multiple support frames 4. Filter mechanisms are installed inside the air inlet duct 5 and the air outlet duct 6. A heat dissipation mechanism is installed inside the air outlet duct 6.

[0020] During ship navigation, the continuous impact of waves and strong winds cause frequent rolling and pitching. The vibrations generated by this rolling are preferentially transmitted through the base 1 to the buffer mechanisms at the upper and lower ends of the control device body 2. These multiple buffer mechanisms can handle the complex rolling directions during navigation, rather than being limited to vibration reduction in a single direction, thus effectively resisting the ship's rolling and pitching. This ensures the stability of the internal electrical components of the device, reduces problems such as loose connections and solder joint detachment caused by vibration, improves the reliability of equipment operation, and provides strong protection for the safe navigation of the ship. Furthermore, the operation of the internal components of the control device body 2 and the harsh environment of high temperature and humidity at sea will cause vibrations to occur within the control device body. The body 2 generates a large amount of heat. Therefore, the heat dissipation mechanism can operate automatically when the internal temperature of the control device body 2 rises. Since the air inlet duct 5 and the air outlet duct 6 are diagonally distributed, the heat dissipation mechanism can guide cold air from the outside into the control device body 2 from the air inlet duct 5. After being guided by multiple air guide slots 7, the cold air can flow through the various electronic components inside, and then carry the hot air out to the outside from the air outlet duct 6. In this way, the heat inside the control device body 2 can be dissipated quickly and effectively, so that the internal temperature of the control device body 2 is always kept within the normal operating temperature range of the electrical components. This greatly reduces the equipment failure rate caused by high temperature and extends the service life of the equipment. At the same time, the filtration mechanism can also prevent external dust and moisture from entering the control device body 2.

[0021] Reference Figure 1The buffer mechanism includes two support blocks 8 fixedly connected to the top of the control device body 2 and the outer wall of the base 1. Connecting blocks 9 are fixedly connected to opposite sides of each support block 8. A sleeve 10 is slidably fitted onto the outer wall of the two connecting blocks 9 at the ends away from the support blocks 8. An elastic damper 11 is provided inside the sleeve 10, with both ends of the elastic damper 11 fixedly connected to one end of each of the two connecting blocks 9. A damping spring 12 is fitted onto the outer wall of the elastic damper 11, with both ends of the damping spring 12 fixedly connected to one end of each of the two connecting blocks 9. Guide blocks are fixedly connected to both sides of the sleeve 10. 13. Both guide blocks 13 have internal grooves, and guide rods 14 are fixedly connected in both grooves. Slider blocks 15 are slidably connected to the outer walls of both guide rods 14. Adjusting rods 16 are symmetrically rotatably connected to both sides of both sliders 15. The ends of multiple adjusting rods 16 away from sliders 15 are rotatably connected to one side of each of the two support blocks 8. Vibration damping springs 17 are sleeved on the outer walls of both guide rods 14. The two ends of the two vibration damping springs 17 are fixedly connected to the inner walls of sliders 15 and grooves, respectively. Buffer and shock-absorbing pads 18 are fixedly connected to the top surfaces of multiple support frames 4.

[0022] During ship navigation, the continuous impact of waves and strong winds cause frequent rocking and turbulence. The vibrations generated by this rocking are transmitted via the base 1 to multiple support blocks 8 at the upper and lower ends of the control device body 2. Affected by the vibration, the support blocks 8 push two connecting blocks 9 to move slightly, causing them to slide closer together at opposite ends and slide inside the sleeve 10. The elastic damper 11 contracts under the thrust of the two connecting blocks 9 and, through its own elasticity, pushes the two connecting blocks 9 in the opposite direction, causing them to reset inside the sleeve 10. This buffers the vibration. Furthermore, the damping spring 12 further enhances the vibration buffering effect. While moving, the two adjusting rods 16 will rotate slightly. At this time, the two adjusting rods 16 will push the slider 15 to slide inside the groove according to the guide rod 14. As the slider 15 moves, it will compress the second damping spring 17, thereby using the elasticity of the second damping spring 17 to buffer the vibration force again. In addition, the multiple buffer damping pads 18 set on the multiple support frames 4 can also absorb the vibration force. In this way, it can cope with the complex swaying direction during the ship's navigation, rather than being limited to the damping of a single direction. This effectively resists the ship's rocking and turbulence, ensures the stability of the electrical components inside the device, reduces problems such as loose connections and detached solder joints caused by vibration, improves the reliability of the equipment operation, and provides a strong guarantee for the safe navigation of the ship.

[0023] Reference Figure 1The heat dissipation mechanism includes multiple cooling fans 19 fixedly connected inside the air outlet duct 6. A temperature sensor 20 is fixedly connected to one side of the control device body 2. The temperature sensor 20 and the multiple cooling fans 19 are electrically connected to an external controller. Waterproof and breathable valves 28 are fixedly connected inside the air inlet duct 5 and the air outlet duct 6. A polytetrafluoroethylene membrane is installed inside the waterproof and breathable valve 28.

[0024] During use, the temperature sensor 20 can monitor the internal temperature of the control device body 2 at all times. When the internal temperature of the control device body 2 is high, multiple cooling fans 19 will be activated by the controller. At this time, as the cooling fans 19 rotate, negative pressure will be gradually generated, which will guide the outside cold air from the air inlet duct 5 into the control device body 2. Through the guidance of multiple air guide slots 7, the cold air can be evenly dispersed and flow through the various electronic components inside the control device body 2 to evenly dissipate heat from the electronic components. Then, the hot air is discharged to the outside through the air outlet duct 6 by the operation of multiple cooling fans 19, thereby achieving rapid heat dissipation. At the same time, the polytetrafluoroethylene membrane set inside the waterproof and breathable valve 28 can give the air inlet duct 5 and the air outlet duct 6 excellent waterproof and breathable performance, which can prevent external moisture from entering the control device body 2 and ensure the air inside the control device body 2 can circulate with the outside air.

[0025] Reference Figure 1 The filtration mechanism includes dustproof nets 21 respectively installed inside the air inlet duct 5 and the air outlet duct 6. Grooves 22 are symmetrically opened on one side of the air inlet duct 5 and the air outlet duct 6. Adjusting blocks 23 are slidably connected in multiple grooves 22. Adhesive plates 24 are fixedly connected to one end of multiple adjusting blocks 23. Baffles 25 are fixedly connected inside the air inlet duct 5 and the air outlet duct 6. One side of the dustproof net 21 can be adhered to one side of the baffle 25. A high-efficiency separation device for prickly pear juice pulp 3 is slidably connected to corresponding guide rods 26. Springs 27 are sleeved on the outer wall of multiple guide rods 26. The two ends of multiple springs 27 are fixedly connected to one side of the adjusting block 23 and the inner wall of the groove 22, respectively.

[0026] During use, the dustproof net 21 effectively prevents external dust from entering the control device body 2. However, after prolonged use, a certain amount of dust will adhere to the outer wall of the dustproof net 21, affecting the ventilation effect of the air inlet duct 5 and the air outlet duct 6. Therefore, the two adjusting blocks 23 can be pulled to move the bonding plates 24 away from each other, so that the two bonding plates 24 gradually separate from the outer wall of the dustproof net 21. At this time, the dustproof net 21 can be quickly removed for cleaning or replacement, and the new dustproof net 21 can be reinserted into the air inlet. The dustproof net 21 is placed inside the air inlet duct 5 and the air outlet duct 6 and is attached to the baffle strip 25. The baffle strip 25 can intercept and limit the position of the dustproof net 21. Then the adjusting block 23 can be released. At this time, according to the guidance of the guide rod 26 and the rebound of the spring 27, the two adjusting blocks 23 will be pushed to drive the bonding plate 24 to reset, so that the two bonding plates 24 are attached to the outer wall of the dustproof net 21 again. Through the limitation of the two bonding plates 24 and the baffle strip 25, the dustproof net 21 can be stabilized inside the air inlet duct 5 and the air outlet duct 6 to prevent it from detaching.

[0027] As a technical optimization of this utility model: the vibrations generated by the frequent rocking of the ship are preferentially transmitted to multiple support blocks 8 at the upper and lower ends of the multiple control device bodies 2 through the base 1. At this time, affected by the vibration, the multiple support blocks 8 will push the two connecting blocks 9 to move slightly, so that the two connecting blocks 9 move closer to each other at opposite ends and slide inside the sleeve 10. The elastic damper 11 will be compressed by the thrust of the two connecting blocks 9 and exert a reverse thrust on the two connecting blocks 9 through its own elasticity, so that the two connecting blocks 9 will be reset inside the sleeve 10, thereby achieving the buffering of vibration. At the same time, the damping effect can be further improved by the setting of the damping spring 12, and the movement of the two connecting blocks 9 can also be optimized. At the same time, it will also cause the two adjusting rods 16 to rotate slightly. At this time, the two adjusting rods 16 will push the slider 15 to slide inside the groove according to the guide rod 14. As the slider 15 moves, it will squeeze the second damping spring 17. In this way, the elasticity of the second damping spring 17 will further buffer the vibration force. In addition, the multiple buffer damping pads 18 set on the multiple support frames 4 can also absorb the vibration force. In this way, through the multiple buffer structure, it can effectively resist the rocking and turbulence during the ship's navigation, ensure the stability of the electrical components inside the device, reduce problems such as loose connections and detached solder joints caused by vibration, improve the reliability of equipment operation, and provide a strong guarantee for the safe navigation of the ship. In addition, during daily ship navigation, the operation of the internal components of the control device 2 and the harsh environment of high temperature and humidity at sea generate a large amount of heat inside the control device 2. Therefore, the temperature sensor 20 can monitor the internal temperature of the control device 2 at all times. When the internal temperature of the control device 2 is high, the controller will start multiple cooling fans 19. At this time, as the cooling fans 19 rotate, a negative pressure will gradually be generated, which will guide the outside cold air from the air inlet 5 into the control device 2. Through the guidance of multiple air guide slots 7, the cold air can be evenly distributed and flow through the various electronic components inside the control device 2, so as to evenly cool the electronic components. Heat dissipation is achieved by the operation of multiple cooling fans 19, which then exhaust the hot air from the air outlet 6 to the outside. This rapid heat dissipation is achieved by the polytetrafluoroethylene membrane inside the waterproof and breathable valve 28, which provides excellent waterproof and breathable performance for the air inlet 5 and the air outlet 6. This prevents external moisture from entering the control device body 2 and ensures air circulation between the control device body 2 and the outside air. This allows the heat inside the control device body 2 to be dissipated quickly and effectively, keeping the internal temperature of the control device body 2 within the normal operating temperature range of the electrical components. This greatly reduces the equipment failure rate caused by high temperature and extends the service life of the equipment. Meanwhile, the dustproof net 21 can effectively prevent external dust from entering the interior of the control device body 2. However, after long-term use, a certain amount of dust will adhere to the outer wall of the dustproof net 21, thus affecting the ventilation effect of the air inlet duct 5 and the air outlet duct 6. Therefore, the two adjusting blocks 23 can be pulled to move the bonding plates 24 away from each other, so that the two bonding plates 24 gradually separate from the outer wall of the dustproof net 21. At this time, the dustproof net 21 can be quickly removed for cleaning or replacement, and the new dustproof net 21 can be reinserted into the air inlet duct 5. The dust filter 21 is placed inside the air inlet duct 6 and attached to the baffle 25. The baffle 25 can block and limit the position of the dust filter 21. Then the adjusting block 23 can be released. At this time, according to the guidance of the guide rod 26 and the rebound of the spring 27, the two adjusting blocks 23 will be pushed to drive the bonding plate 24 to reset, so that the two bonding plates 24 are attached to the outer wall of the dust filter 21 again. Through the limitation of the two bonding plates 24 and the baffle 25, the dust filter 21 can be stabilized inside the air inlet duct 5 and the air outlet duct 6 to prevent it from detaching.
