Description

Technical Field

[0001] This utility model relates to the technical field of motor protection devices, and in particular to a high-protection-level wind inlet and outlet protection structure for marine motors. Background Technology

[0002] Because marine electric motors operate in harsh environments, ventilation and heat dissipation are very important. To ensure smooth ventilation and meet the heat dissipation requirements of the motors, as well as the protection level requirements of the motors under harsh marine environments (high humidity, salt spray, oil pollution), there are high requirements for the air intake and exhaust protection devices of the motors.

[0003] Existing marine electric motor inlet and outlet protection structures can only meet the IP23 protection level, which cannot completely isolate rainwater and foreign objects from the outside of the motor. As a result, they can enter the motor and damage the motor insulation, greatly reducing the service life of the motor and causing adverse factors during the use of the motor. Utility Model Content

[0004] In response to the shortcomings of the existing production technology, the applicant provides a reasonably structured and highly protective air intake and exhaust structure for marine electric motors. This structure effectively protects the motor from air ingress and egress, achieving an IP44 protection rating, meeting the requirements for marine electric motors, providing excellent protection, and extending the motor's service life.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A high-protection-level marine electric motor inlet and outlet air protection structure includes a flange. One end of the flange is equipped with a wind cover, which is a hollow cuboid structure. The outer end face and bottom of the wind cover are both open. A primary isolation plate and a secondary isolation plate are respectively installed on the outer end face and bottom of the wind cover. The other end of the flange is equipped with a mesh plate mounting groove that communicates with the wind cover. A stainless steel mesh plate is embedded in the mesh plate mounting groove.

[0007] As a further improvement to the above technical solution:

[0008] The flange has multiple evenly spaced locking holes and is connected to the motor base.

[0009] The mesh panel mounting groove has a quadrilateral structure.

[0010] A slot is provided in the middle of the mesh plate mounting groove.

[0011] The stainless steel mesh panel adopts a modular structure, which is formed by stacking three layers of mesh panels and providing edging around the three layers of mesh panels. The edging matches the installation groove of the mesh panel.

[0012] The mesh size of the stainless steel mesh plate is less than or equal to 1 mm.

[0013] The primary and secondary isolation plates have the same structure, both consisting of multiple angle steels evenly spaced from one end to the other.

[0014] The beneficial effects of this utility model are as follows:

[0015] This utility model has a compact and reasonable structure and is easy to operate. Through the cooperation of components such as the wind cover, primary isolation plate, secondary isolation plate and stainless steel mesh plate, it can easily achieve the protection of the motor's air intake and exhaust, effectively isolate the motor, protect the motor and ensure the reliability of the motor's operation.

[0016] The IP44-protected air inlet and outlet structure provided by this utility model can provide a good airflow path for the motor, ensure unobstructed airflow, and improve the service life of the motor. The structure is easy to install, has low manufacturing cost, and is simple and convenient to maintain and operate without professional personnel.

[0017] The IP44 protection rating marine electric motor air inlet and outlet protection structure provided by this utility model not only meets the heat dissipation requirements of the electric motor, but also provides excellent protection for the electric motor. Attached Figure Description

[0026] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0027] like Figures 1-7 As shown, the high-protection-level marine motor inlet and outlet air protection structure of this embodiment includes a flange 1, a wind shield 5 installed at one end of the flange 1, the wind shield 5 is a hollow cuboid structure, the outer end face and bottom of the wind shield 5 are both open, a primary isolation plate 6 and a secondary isolation plate 7 are respectively installed on the outer end face and bottom of the wind shield 5; the other end of the flange 1 is equipped with a mesh plate mounting groove 2 that is in communication with the wind shield 5, and a stainless steel mesh plate 3 is embedded in the mesh plate mounting groove 2.

[0028] Flange 1 has multiple evenly spaced locking holes and is connected to the motor base.

[0029] The mesh plate mounting groove 2 has a quadrilateral structure.

[0030] A slot 4 is provided in the middle of the mesh plate mounting slot 2.

[0031] The stainless steel mesh panel 3 adopts a modular structure. The stainless steel mesh panel 3 is made of three layers of mesh panels stacked together, and the three layers of mesh panels are surrounded by edging, which matches the mesh panel mounting groove 2.

[0032] The mesh size of stainless steel mesh plate 3 is less than or equal to 1mm.

[0033] The primary isolation plate 6 and the secondary isolation plate 7 have the same structure, both consisting of multiple angle steels evenly spaced from one end to the other.

[0034] The specific structure of the high-protection-level marine electric motor inlet and outlet air protection structure described in this utility model is as follows:

[0035] The system includes an inlet / outlet shroud 5 installed on the outside of the motor. Specifically, the shroud 5 has a rectangular structure with a large internal space. A primary isolation plate 6 is installed on the rear end face of the shroud 5 (opposite to the stainless steel mesh plate 3), and a secondary isolation plate 7 is installed at the bottom of the shroud 5. A flange 1 is welded to the front end face of the shroud 5. The flange 1 has multiple locking holes and is directly fixed to the base of the marine motor. At the same time, a mesh plate mounting groove 2 is welded to the outer end of the flange 1. A stainless steel mesh plate 3 is embedded in the mesh plate mounting groove 2. The mesh of the stainless steel mesh plate 3 can prevent solid objects larger than 1mm from passing through.

[0036] The primary isolation plate 6 and the secondary isolation plate 7 have the same structure, both consisting of several equilateral angle steel baffles. The equilateral angle steel baffles are perpendicular to one side wall of the wind shroud 5 and are welded together.

[0037] The stainless steel mesh plate 3 is placed in the mesh plate mounting groove 2. It adopts a detachable structure and is easy to replace.

[0038] The air inlet and outlet protection structure uses three layers of protection: primary isolation plate 6, secondary isolation plate 7, and stainless steel mesh plate 3, to completely isolate water or other foreign objects from the outside of the motor, so that the motor meets the IP44 protection level requirements.

[0039] In actual operation, external wind and water enter the interior of the fan cover 5 through the primary isolation plate 6. Some water flows to the secondary isolation plate 7 and is isolated by the secondary isolation plate 7 to prevent water from entering the motor. At the same time, the stainless steel mesh plate 3 effectively isolates debris. The overall operation is reliable, effectively protects the motor, and extends the service life of the motor.

[0040] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
