Description

Technical Field

[0001] This application relates to the technical field of generator protection devices, specifically a marine generator winding protection device. Background Technology

[0002] In modern ship electrical systems, generators are important equipment for ship power and electricity supply, bearing the electrical energy needs of the ship during navigation. In order to ensure the stability and reliability of the ship's electrical system, the protection of generator windings is particularly important. Generator windings are a key component of the generator, and their main function is to convert mechanical energy into electrical energy through the principle of electromagnetic induction.

[0003] Because marine generators operate in a humid marine environment, even though the windings are located inside the generator casing, the windings can still become damp, leading to decreased insulation performance and corrosion of metal parts, which seriously affects the normal operation and service life of the generator.

[0004] Therefore, this application provides a marine generator winding protection device to solve the above-mentioned problems. Utility Model Content

[0005] This application provides a marine generator winding protection device, which aims to solve the problem mentioned in the background art that, because marine generators operate in a humid marine environment, even though the windings are located inside the generator housing, the windings may still become damp, leading to a decrease in insulation performance.

[0006] To achieve the above objectives, this application provides the following technical solution: a marine generator winding protection device, comprising a base and a generator mounted on the base, wherein a fixing frame is provided at the lower end of the base, a lower housing is provided at the upper end of the fixing frame, and an upper housing is provided at the upper end of the lower housing;

[0007] The upper housing is equipped with a moisture-proof mechanism.

[0008] The upper housing is equipped with a partition frame, and several condensing plates are evenly distributed on the upper end of the partition frame. Support seats connected to the partition frame are symmetrically installed on the condensing plates. Air guide ducts are symmetrically arranged on the partition frame. Exhaust pipes and air inlet pipes are arranged opposite each other on the upper housing, forming the main structure of the device. The condensing plates condense and dehumidify the humid air, and the air guide ducts guide the airflow path, thereby achieving moisture protection for the generator.

[0009] Preferably, both the exhaust pipe and the inlet pipe are fixedly installed with support frames, and each support frame is equipped with an axial flow fan. The active ventilation system improves air circulation efficiency, enhances the dehumidification effect of the moisture-proof mechanism, and prevents the generator winding insulation from aging due to a humid and hot environment.

[0010] Preferably, the partition frame is symmetrically provided with guide grooves, and the exhaust pipe is symmetrically distributed with drain outlets aligned with the guide grooves. The guide grooves and drain outlets form a drainage channel to ensure that condensate is discharged in time and to prevent liquid water from flowing back into the generator.

[0011] Preferably, an inner ring is fixedly installed on the inner wall of the air guide duct, and a filter cylinder overlapping the inner ring is provided inside the air guide duct, and a filter element is provided inside the filter cylinder.

[0012] Preferably, the air duct is inserted into the partition frame and fixedly connected by bolts.

[0013] Preferably, the separator rack is provided with a storage trough.

[0014] This protective device features a moisture-proof mechanism that divides the interior of the upper housing into layers. The condenser plate is fixed to the partition frame via a support base, and a guide duct runs through the partition frame. External air enters through the air inlet duct and flows through the guide duct. As the air flows through the guide duct, the humid air comes into contact with the condenser plate and condenses. The water vapor is discharged along the guide channel, while the dry air circulates through the exhaust duct. The condenser plate condenses the water vapor through cooling or temperature difference effects, the guide channel drains water quickly, and the desiccant in the storage tank absorbs residual water vapor, forming a triple protection of condensation, drainage, and drying, effectively reducing the humidity inside the generator compartment.

[0015] This protective device features a detachable filter cartridge secured by an inner ring, which can be easily replaced by pulling upwards. The upper housing is openable and closable, facilitating regular replacement of the filter element and cleaning of scale buildup on the condenser plate surface. Attached Figure Description

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] This embodiment provides a marine generator winding protection device, such as... Figure 1-5 As shown, the protection device includes a base 1 and a generator 3 mounted on the base 1. A fixing frame 2 is provided at the lower end of the base 1, a lower housing 4 is provided at the upper end of the fixing frame 2, and an upper housing 5 is provided at the upper end of the lower housing 4.

[0025] The upper casing 5 is equipped with a moisture-proof mechanism 6 inside;

[0026] The upper shell 5 is equipped with a partition frame 61. Several condenser plates 62 are evenly distributed on the upper end of the partition frame 61. Support seats 63 connected to the partition frame 61 are symmetrically installed on the condenser plates 62. Guide air ducts 65 are symmetrically arranged on the partition frame 61. Exhaust pipe 51 and air inlet pipe 52 are arranged opposite each other on the upper shell 5.

[0027] Specifically, the base 1 supports the lower shell 4 and the upper shell 5 through the fixing frame 2, forming a protective outer shell for the generator 3. The partition frame 61 of the moisture-proof mechanism 6 divides the interior of the upper shell 5 into layers. The condenser plate 62 is fixed to the partition frame 61 through the support seat 63. The air guide duct 65 passes through the partition frame 61. External air enters from the air inlet duct 52. When it flows through the air guide duct 65, the humid air comes into contact with the condenser plate 62 and condenses. The water vapor is discharged along the guide groove 64. The dry air circulates through the exhaust duct 51. The condenser plate 62 condenses the water vapor through refrigeration or temperature difference effect. The guide groove 64 drains water quickly. The desiccant in the storage tank 66 adsorbs the residual water vapor, forming a triple protection of condensation, drainage and drying, which effectively reduces the humidity inside the generator 3. The bolt connection between the fixing frame 2 and the base 1, and the insertion and fixing of the air guide duct 65 and the partition frame 61 enhance the device's resistance to ship vibration. The connection between the upper shell 5 and the lower shell 4 is equipped with a sealing design, specifically a sealing gasket that matches the shape of the upper shell 5 and the lower shell 4, to prevent seawater splashing in.

[0028] Both the exhaust duct 51 and the inlet duct 52 are fixedly installed with support frames, and axial flow fans are installed on the support frames.

[0029] More specifically, the axial flow fans in the exhaust duct 51 and the air inlet duct 52 force air circulation, accelerate the heat exchange between the humid air and the condenser plate 62, and improve the dehumidification efficiency. The condenser plate 62 integrates heat conduction pipes, which are connected to the ship's central cooling system. The Peltier effect semiconductor cooling chip provides a cold source to ensure that the surface temperature of the condenser plate 62 is lower than the air dew point temperature.

[0030] The symmetrical layout of the exhaust duct 51 and the intake duct 52 enables air convection, adapting to the ventilation needs of ships under different sailing attitudes. The open design of the storage tank 66 allows for quick replacement of the desiccant, coping with the long-term high humidity environment during ocean voyages.

[0031] The partition frame 61 is symmetrically provided with guide grooves 64, and the exhaust pipe 51 is symmetrically provided with drain ports 53 aligned with the guide grooves 64.

[0032] Furthermore, the guide groove 64 on the partition 61 collects water droplets on the surface of the condenser plate 62 and discharges them out of the housing through the drain port 53 to prevent condensate from accumulating.

[0033] An inner ring 651 is fixedly installed on the inner wall of the air duct 65. A filter cartridge 652 is installed inside the air duct 65, which overlaps the inner ring 651. A filter element is installed inside the filter cartridge 652.

[0034] Furthermore, the inner ring 651 of the inner wall of the air duct 65 supports the filter cartridge 652. The filter element adsorbs impurities such as salt particles and oil stains in the air, purifying the air entering the shell. The filter element of the filter cartridge 652 filters moisture, salt spray and oil stains in the air, avoiding corrosion of the windings by the humid and hot environment and high salt of the ship, and extending the service life of the equipment.

[0035] A rubber sealing ring is provided at the edge of the inner ring 651, and the lower end of the filter cartridge 652 is interference-fitted with the inner ring 651 to ensure that air only flows through the filter element after filtration, and to avoid bypass leakage of unfiltered air.

[0036] The air duct 65 is inserted into the partition frame 61 and fixedly connected by bolts. The partition frame 61 is provided with a material storage trough 66.

[0037] It should be noted that the air duct 65 and the partition frame 61 are fixed with bolts to form a rigid connection, ensuring the stability of the air flow path. The storage tank 66 is used to store desiccant to help absorb residual moisture in the air.

[0038] The guide channel 64 is inclined at 45° toward the drain port 53. The bottom of the channel is coated with a hydrophobic coating and the inner wall is smooth without dead corners, ensuring that the condensate is discharged quickly under the action of gravity and avoiding stagnation.

[0039] In use, the base 1 supports the lower shell 4 and the upper shell 5 through the fixing frame 2, forming a protective shell for the generator 3. The partition frame 61 of the moisture-proof mechanism 6 divides the interior of the upper shell 5 into layers. The condenser plate 62 is fixed to the partition frame 61 through the support seat 63. The air guide duct 65 passes through the partition frame 61. External air enters from the air inlet duct 52. When it flows through the air guide duct 65, the humid air comes into contact with the condenser plate 62 and condenses. The water vapor is discharged along the guide groove 64. The dry air circulates through the exhaust pipe 51. The condenser plate 62 condenses the water vapor through refrigeration or temperature difference effect. The guide groove 64 drains water quickly. The desiccant in the storage tank 66 adsorbs the residual water vapor, forming a triple protection of condensation, drainage and drying, which effectively reduces the humidity inside the generator 3 compartment.

[0040] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
