Description

Technical Field

[0001] This utility model relates to the field of control box protection, specifically an anti-salt spray device for a marine separator electrical control box. Background Technology

[0002] Marine separators are key equipment in marine machinery used to separate oil, water, and solid impurities, achieving efficient purification through centrifugal force. The electrical control box of the marine separator is the "brain" of the separation system, enabling automatic control of the separator's operating conditions through electrical control.

[0003] Because marine separator electrical control boxes are located in coastal environments, the salt spray content in the marine atmosphere is much higher than on land, especially in nearshore or deck areas, where the salt spray deposition rate can reach several grams per square meter per day. If the control box is not protected, the internal components will be quickly covered by salt spray. Currently, marine separator electrical control boxes are designed with a relatively enclosed structure to prevent salt spray corrosion, resulting in extremely poor heat dissipation performance.

[0004] Patent CN114914816A discloses an automated electrical control box with a rapid heat dissipation device, comprising an outer box, an inner box, and a cover. An annular air duct is formed between the walls of the outer and inner boxes. When the cover is closed on the outer box, the cover and inner box form a sealed space. Modular fins are detachably installed in the inner box, with both ends of each fin extending outwards into the annular air duct. A cooling fan for dissipating heat from the modular fins is installed in the annular air duct. The sealed space ensures dustproof, waterproof, and salt spray protection, thus providing better protection for the internal electrical components and adapting to extreme outdoor environments. Simultaneously, the annular air duct, combined with the modular fins and cooling fan, rapidly dissipates heat generated by the electrical components, significantly improving the heat dissipation performance of the electrical control box. Furthermore, the modular fins enable modular installation and quick replacement of electrical components.

[0005] However, the above technical solution has the following problems when used: 1. The module fins are cooled by a cooling fan. The airflow direction of the module fins and the cooling fan is perpendicular to each other. The air can only pass over the side of the fins. The parallel airflow cannot effectively break the thermal boundary layer, resulting in low heat exchange efficiency. 2. External air directly reaches the module fin surface through the outer casing, and a large amount of salt easily condenses on the module fin surface, affecting the heat dissipation effect on the inner casing.

[0019] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0020] An embodiment of the present invention is shown in conjunction with the accompanying drawings.

[0021] Example 1: Please see Figures 1-8This is the first embodiment of the present invention. This embodiment provides a salt spray prevention device for the electrical control box of a marine separator, including a control box assembly 1; a water cooling circulation assembly 2 for cooling the control box assembly 1; a protective assembly 3 for intercepting salt spray; and a blowing assembly 4 and a dust collection assembly 5 for cleaning salt. The control box assembly 1 includes: an aluminum alloy housing 101; heat dissipation fins 109 fixed on the left and right sides of the aluminum alloy housing 101; a box cover 104 installed at the front end of the aluminum alloy housing 101 by hinge rotation; and a sealing strip 105 pasted on the side of the box cover 104 near the aluminum alloy housing 101. The heat dissipation fins 109 have a certain tilt angle so that salt can slide down. The water cooling circulation assembly 2 includes: a water cooling pipe 207 fixed inside the heat dissipation fins 109; a nano-ceramic heat dissipation coating is sprayed on the surface of the heat dissipation fins 109, avoiding the water cooling pipe 207, which has both high thermal conductivity and salt spray isolation capability; and an epoxy resin anti-corrosion paint is applied to the exposed section of the water cooling pipe 207 to prevent salt from adhering. The protective component 3 includes: a protective cover 301 that can be detachably installed on the outside of the heat dissipation fins 109; a filter screen 302 fixed inside the protective cover 301; a support block 304 welded to one side of the protective cover 301; a support spring 305 fixed to the side of the support block 304; and a hollow rubber ball 306 fixed to the end of the support spring 305. The inner surface of the filter screen 302 is also provided with non-woven fabric. When the salt spray particles are small, they can enter the interior of the filter screen 302 with the gas. The non-woven fabric intercepts the salt spray and reduces the salt adhering to the surface of the heat dissipation fins 109. The blower assembly 4 includes: a blower nozzle 403 disposed on the side of the heat sink fins 109; and a blower head 405 disposed on the side of the hollow rubber ball 306.

[0022] It should be noted that the cover 104 is sealed to the aluminum alloy shell 101 by the sealing strip 105, which can prevent salt spray. The heat dissipation fins 109 are set on the outside, and the water cooling pipes 207 are used to achieve heat dissipation and cooling. The blower nozzle 403 can blow external airflow onto the heat dissipation fins 109, which can not only increase the airflow speed on the surface of the heat dissipation fins 109, but also blow off the salt deposited on the surface of the heat dissipation fins 109. The blower head 405 can blow the hollow rubber ball 306. Under the action of the support spring 305, the hollow rubber ball 306 swings and collides with the filter screen 302, which can shake off the salt on the filter screen 302.

[0023] Furthermore, the control box assembly 1 also includes: an aluminum alloy bracket 102 that is fixed to the inside of the aluminum alloy housing 101 by bolts; thermally conductive silicone grease is filled between the aluminum alloy bracket 102 and the aluminum alloy housing 101.

[0024] It should be noted that the thermal grease is used to fill the gap between the aluminum alloy bracket 102 and the aluminum alloy housing 101. The aluminum alloy bracket 102 is used to install the electrical components of the marine separator electrical control box. The heat emitted by the electrical components can be transferred to the aluminum alloy housing 101 through the aluminum alloy bracket 102.

[0025] Furthermore, the control box assembly 1 also includes: a PLC controller 103 bolted to the front end of the aluminum alloy bracket 102; a display screen 106 embedded inside the cover 104; a buzzer 107 positioned above the display screen 106; and a temperature and humidity sensor 108 bolted to the surface of the aluminum alloy housing 101.

[0026] It should be noted that the temperature and humidity sensor 108 is used to collect environmental data and obtain temperature and humidity data. The PLC controller 103 is electrically connected to the display screen 106, the buzzer 107 and the temperature and humidity sensor 108. The temperature and humidity sensor 108 is a salt spray resistant sensor.

[0027] Furthermore, the water-cooled circulation assembly 2 also includes: a top water tank 201 placed on top of the aluminum alloy housing 101; a bottom water tank 204 placed at the bottom of the aluminum alloy housing 101; a connecting pipe 202 fixed between the bottom water tank 204 and the top water tank 201; and a water pump 205 installed in the middle of the connecting pipe 202 via a flange.

[0028] It should be noted that the water pump 205 is connected to the PLC controller 103. When the water pump 205 is working, the coolant in the bottom water tank 204 can enter the top water tank 201 through the connecting pipe 202, and the coolant in the top water tank 201 can re-enter the bottom water tank 204 through the water cooling pipe 207 to achieve coolant circulation.

[0029] Furthermore, the water-cooled circulation assembly 2 also includes: a semiconductor cooling chip 203 fixed to the sides of the bottom water tank 204 and the top water tank 201; and fixing ear plates 206 fixed to the left and right sides of the bottom water tank 204 and the top water tank 201; the two ends of the water-cooled pipe 207 are respectively connected to the bottom water tank 204 and the top water tank 201.

[0030] It should be noted that the cooling end of the semiconductor cooling chip 203 is in close contact with the bottom water tank 204 and the top water tank 201. The semiconductor cooling chip 203 cools the bottom water tank 204 and the top water tank 201, while the water cooling pipe 207 can carry away the heat from the heat dissipation fins 109, thereby achieving the effect of cooling the aluminum alloy shell 101 through the heat dissipation fins 109.

[0031] In this embodiment, the control box assembly 1 is provided, and the box cover 104 is sealed to the aluminum alloy shell 101 by the sealing strip 105 to prevent salt spray. The outer side is provided with heat dissipation fins 109, which are used in conjunction with water cooling pipes 207 to achieve heat dissipation and cooling. The blower nozzle 403 can blow external airflow to the heat dissipation fins 109, which can increase the airflow speed on the surface of the heat dissipation fins 109, and achieve high-speed heat dissipation in conjunction with the water cooling circulation assembly 2. The protective component 3 can filter salt spray in the environment under the action of filter screen 302. The blower head 405 can blow the hollow rubber ball 306. The hollow rubber ball 306 swings under the action of support spring 305. The hollow rubber ball 306 collides with the filter screen 302, which can shake off the salt on the filter screen 302. The dust collection component 5 collects the salt.

[0032] Example 2: Please see Figures 4-8 This is the second embodiment of the present invention, which provides an anti-salt spray device for the electrical control box of a marine separator.

[0033] Furthermore, the protective component 3 also includes: a connector 303 fixed to the middle of the bottom end of the protective cover 301; and cover ear plates 307 welded to the upper and lower sides of the protective cover 301; the cover ear plates 307 are fixed to the fixed ear plates 206 by screws.

[0034] It should be noted that the protective cover 301 is fixed to the fixed ear plate 206 by the cover ear plate 307, and the protective cover 301 can be disassembled and cleaned.

[0035] Furthermore, the blower assembly 4 also includes: a blower 401 fixed to the rear end of the aluminum alloy housing 101; an air duct 402 fixed to the air outlet end of the blower 401; and a hollow plate 404 fixed to the end of the air duct 402.

[0036] It should be noted that the air inlet of blower 401 is equipped with filter material, including an ultra-fine glass fiber filter layer. The ultra-fine glass fiber paper as filter material can not only capture particulate dust and various suspended matter smaller than 0.5μm, with high filtration efficiency, low resistance and large dust holding capacity, but also intercept moisture and remove micro-droplets through the filter layer, so that salt cannot exist independently, thereby achieving the purpose of removing salt and preventing salt from entering blower 401.

[0037] Furthermore, the blower nozzles 403 are evenly distributed at equal intervals along the surface of the hollow plate 404, and both the blower nozzles 403 and the blower head 405 are connected to the hollow plate 404.

[0038] It should be noted that the blower 401 delivers the filtered airflow to the hollow plate 404 through the air duct 402, and the airflow is blown outward through the blower nozzle 403 and blower head 405 on the hollow plate 404.

[0039] Furthermore, the dust collection assembly 5 also includes: a hose 503 threadedly connected to the lower part of the connector 303; a dust collection box 501 fixed to the end of the hose 503; and a dust pump 502 installed on the side of the dust collection box 501 via a flange.

[0040] It should be noted that a filter material is installed between the vacuum pump 502 and the dust collection box 501 to intercept salt particles from entering the vacuum pump 502, while the other end of the vacuum pump 502 can exhaust air outward. Since the connector 303 is threadedly connected to the hose 503, the protective component 3 and the dust collection component 5 can be easily separated after the protective cover 301 is removed.

[0041] In this embodiment, the blower 401 can deliver the filtered airflow to the hollow plate 404 through the air duct 402 via the blower assembly 4. The airflow is blown outward through the blower nozzle 403 and blower head 405 on the hollow plate 404, thereby achieving the effect of cooling the heat dissipation fins 109. In addition, it can be used with the dust collection assembly 5 to collect salt.

[0042] Example 3: Please see Figure 8 This is the third embodiment of the present invention, which provides an environmental control method, including the following steps: S1. Temperature and humidity sensor 108 monitors the temperature and humidity inside the protective cover 301 and transmits the monitored data to PLC controller 103. S2, PLC controller 103 controls the operation of the corresponding actuators based on the monitored data; S3. When the temperature exceeds the threshold, the PLC controller 103 controls the blower 401 and the dust pump 502 to work. The blower 401 blows the external airflow onto the heat sink 109, which works with the water cooling circulation component 2 to achieve rapid cooling. At the same time, the salt is blown off, and the dust collection box 501 collects the blown-off salt. S4. When the humidity exceeds the threshold, the PLC controller 103 controls the buzzer 107 to sound an alarm, reminding personnel to manually shut down the equipment. S5. If the equipment is not shut down within the specified time, the PLC controller 103 can automatically stop the machine.

[0043] Working principle: The cover 104 is sealed to the aluminum alloy shell 101 by the sealing strip 105, preventing external salt spray from entering the aluminum alloy shell 101, thus achieving a salt spray prevention effect. The aluminum alloy bracket 102 is used to install the electrical components of the marine separator's electrical control box. The heat dissipated by the electrical components can be transferred through the aluminum alloy bracket 102 to the aluminum alloy shell 101 and then to the heat dissipation fins 109. The water pump 205 and the thermoelectric cooler 203 work simultaneously. The cooling end of the thermoelectric cooler 203 is connected to... The bottom water tank 204 and the top water tank 201 are fitted together. The semiconductor cooling chip 203 cools both the bottom and top water tanks. The coolant in the bottom water tank 204 can enter the top water tank 201 through the connecting pipe 202, while the coolant in the top water tank 201 can re-enter the bottom water tank 204 through the water-cooling pipe 207, thus achieving coolant circulation. The water-cooling pipe 207 can remove heat from the heat dissipation fins 109, allowing the heat to reach its maximum temperature. Regarding the cooling effect on the aluminum alloy casing 101, since the inner surface of the filter screen 302 is also covered with non-woven fabric, when the salt spray particles are small, they can enter the interior of the filter screen 302 with the gas. The non-woven fabric intercepts the salt spray, reducing the salt adhering to the surface of the heat dissipation fins 109. Since the heat dissipation fins 109 have a certain amount of heat, after the salt spray moisture evaporates, the salt will remain on the surface of the heat dissipation fins 109, but the salt cannot penetrate the non-woven fabric. When the temperature exceeds the threshold, the PLC controller 103 controls the blower 401 and the dust pump. When 502 is activated, the blower 401 blows external airflow onto the heat dissipation fins 109, causing the salt on the heat dissipation fins 109 to slide down into the protective cover 301. At the same time, the blower head 405 blows the hollow rubber ball 306, which swings under the action of the support spring 305. The hollow rubber ball 306 collides with the filter screen 302, shaking off the salt on the filter screen 302. At this time, the salt inside the filter screen 302 can enter the dust collection box 501 through the hose 503.

[0044] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
