Technical Field

[0001] This utility model relates to the field of motor ventilation and heat dissipation technology, specifically a high-efficiency motor ventilation device. Background Technology

[0002] An electric motor is a device that converts electrical energy into mechanical energy. It uses an energized coil to generate a rotating magnetic field, which acts on the rotor to form a magnetoelectric torque. During operation, the motor generates a certain amount of heat. In order to ensure the normal operation of the motor and ensure its service life, ventilation and heat dissipation are required. In the existing technology, auxiliary ventilation and heat dissipation are generally used. This involves installing an internal fan on the non-use end of the motor shaft to drive airflow and create airflow to cool the tail end of the motor.

[0003] However, this method only reaches a limited area with cold air, resulting in low heat exchange efficiency and thus an insignificant heat dissipation effect. Therefore, in order to address the above problems, in-depth research was conducted, leading to this case. Utility Model Content

[0020] 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.

[0021] Example: Please refer to Figure 1-5 A high-efficiency motor ventilation device includes a base 8, a support block 7 fixed to the top of the base 8, and a housing 4 fixed to the top of the support block 7. Multiple heat dissipation fins 3 are installed on the outer wall of the housing 4. A vertical plate 6 is fixed to one end of the top of the base 8, and a protective shell 9 is installed on one end of the vertical plate 6. A dust filter 13 is embedded in one end of the protective shell 9. A rotating shaft 5 is provided inside the housing 4, and one end of the rotating shaft 5 extends to the outside of the housing 4. The other end of the rotating shaft 5 extends into the inside of the protective shell 9 and is equipped with an exhaust fan 11. Multiple air guide pipes 1 are installed on the inner wall of the vertical plate 6, and one end of each air guide pipe 1 extends to the outside of the housing 4. Multiple through holes are opened on the outer wall of the air guide pipe 1.

[0022] Specifically, such as Figure 1 and Figure 2 As shown, when the motor is working, the heat dissipation fins 3 are used to assist the motor housing 4 in heat dissipation, so that the heat can be guided to the heat dissipation fins 3. At the same time, the rotating shaft 5 drives the exhaust fan 11 to rotate, causing the airflow to enter the air duct 1 from the outside through the dust filter 13, be guided by the air duct 1, and finally blown from the through hole on the outer wall of the air duct 1 to the outer wall of the heat dissipation fins 3. The cold air can fully contact the heat to exchange heat, which improves the efficiency of ventilation and heat dissipation.

[0023] The protective shell 9 has a container 12 inside;

[0024] The top of the container 12 extends above the protective shell 9 and is fitted with a mounting frame 10, and a cover plate 23 is fitted at the top of the mounting frame 10.

[0025] Dustproof nets are embedded in both the front and rear ends of the container 12. Two positioning grooves are opened at the bottom inside the protective shell 9, and a matching positioning post is installed at the bottom of the container 12.

[0026] Specifically, such as Figure 2 and Figure 5 As shown, some cooling ice crystals can be placed inside the container 12. When the airflow enters from the outside, it will carry away some of the cold air through this place, thereby lowering the temperature of the cold air and further improving the heat dissipation efficiency.

[0027] Multiple U-shaped fixing blocks 2 are installed on the outer wall of the upright plate 6. Multiple fixing boxes 21 are installed at the corresponding position on one end of the outer wall of the protective shell 9. Each fixing box 21 has a moving strip 22 inside. Each fixing box 21 has a U-shaped limit buckle 20 on the outside. The two sides inside the limit buckle 20 are connected to the two sides of the moving strip 22 through a rotating shaft.

[0028] A fixing ring plate 17 is fixed to the outer wall of the protective shell 9, and multiple rotating rods 18 are rotatably installed on the outer wall of the fixing ring plate 17. One end of each rotating rod 18 is connected to one end inside the fixing box 21 through a rotating shaft. Gears 19 are fixed to the outer wall of the rotating rods 18 on the outside of the fixing box 21. A toothed ring 14 is rotatably installed on one side of the fixing ring plate 17, and the toothed ring 14 meshes with the gear 19.

[0029] The outer wall of the rotating rod 18 inside the fixed box 21 is provided with external threads, and the inner wall of the moving bar 22 is provided with matching internal threads. The moving bar 22 and the rotating rod 18 form a threaded engagement. The inner wall of the fixed box 21 is provided with a guide groove, and the outer wall of the moving bar 22 is provided with a guide block. The moving bar 22 forms a sliding connection with the fixed box 21 through the engagement between the guide block and the guide groove.

[0030] The inner wall of the toothed ring 14 is threaded with a screw 15, and the two ends of the screw 15 extend to the two ends of the toothed ring 14 respectively. One end of the fixed ring plate 17 is provided with a matching threaded groove 16.

[0031] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the protective shell 9 can be removed from the upright plate 6 to clean the exhaust fan 11 and the protective shell 9. During installation, align the fixing block 2 and the fixing box 21 one by one, and rotate the limit buckle 20 so that it is fastened to the outside of the fixing block 2. Then, rotate the toothed ring 14 by the screw 15, so that multiple gears 19 rotate synchronously. This will drive the rotating rod 18 to rotate. Through the threaded engagement between the rotating rod 18 and the moving bar 22, the moving bar 22 pulls the limit buckle 20 to move. The limit buckle 20 finally fastens into the groove of the fixing block 2, completing the splicing and fixing between the fixing block 2 and the fixing box 21. At this time, the screw 15 and the threaded groove 16 are aligned. Rotate the screw 15 to engage with the threaded groove 16 to fix the position of the toothed ring 14. Otherwise, the disassembly operation can be performed.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
