Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to an explosion-proof motor with segmented heat dissipation. Background Technology

[0002] Explosion-proof motors are motors that can be used in flammable and explosive environments. They do not generate electrical sparks during operation, effectively preventing the motor from causing explosions of surrounding flammable and explosive materials. They are widely used in coal mines, oil and gas, petrochemical, and chemical industries. Furthermore, they play an important role in textiles, metallurgy, urban gas, transportation, grain and oil processing, papermaking, and pharmaceuticals.

[0003] Regarding the aforementioned technologies, the existing motors have the following drawbacks: the motor housing is cast in one piece. If the cast housing is damaged by bumps or cracks (such as damage to the explosion-proof surface), it is almost impossible to repair it individually and the whole motor must be replaced, resulting in extremely high maintenance costs. The maintenance efficiency for internal components such as windings and bearings is also low. Therefore, this utility model provides an explosion-proof motor with segmented heat dissipation.

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.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Example 1: Reference Figure 1-4 The explosion-proof motor with segmented heat dissipation, as shown, includes a fixing plate 1 for fixing the core components of the motor and providing a mounting base. Multiple segmented heat dissipation components are provided on the outer side of the fixing plate 1, allowing independent heat dissipation for different heat-generating areas of the motor to prevent concentrated heat accumulation. Each segmented heat dissipation component includes a housing 2 located on the outer side of the fixing plate 1, forming independent heat dissipation spaces to prevent external environmental interference with the internal heat dissipation structure and enhance the overall explosion-proof performance of the motor. Multiple heat dissipation plates 3 are installed on the inner side of the housing 2 to quickly conduct heat from inside the motor to the outside. Multiple heat dissipation holes 5 are opened on the inner side of the end of the heat dissipation plate 3 extending to the outside of the housing 2 to increase the contact area with air and accelerate heat dissipation. Multiple slots are opened on the end of the heat dissipation plate 3 extending into the housing 2, and each slot contains a matching phase change capsule 7 that absorbs heat through phase change to maintain a stable internal temperature of the motor. Multiple outer shells 2 are provided with a common centralized heat dissipation component on their outer sides to concentrate and dissipate heat from the heat dissipation components in each sub-area, thereby improving the overall heat dissipation efficiency. The centralized heat dissipation component includes a heat dissipation shell 4 on the outer side of the outer shell 2, which forms a centralized heat dissipation channel and coordinates the heat dissipation path. A positioning plate 8 is fixedly connected to the inner wall side of the heat dissipation shell 4 to fix the position of the heat dissipation fins and ensure their stable operation. Multiple heat dissipation fins 9 are provided through the outer side of the positioning plate 8 to increase the heat dissipation area and accelerate the transfer of heat to the outside air. Multiple ventilation holes 6 are opened on the outer side of the heat dissipation shell 4 to promote air circulation and remove heat from the heat dissipation shell. A groove 11 is opened on the outer side of the outer shell 2. A fixing ring 10 for connecting the outer shell and the heat dissipation shell is fixedly connected to the outer side of the heat dissipation shell 4. The fixing ring 10 is provided with external threads on its outer side, and the inner wall side of the groove 11 is provided with internal threads. The fixing ring 10 and the groove 11 are threadedly connected.

[0020] Example 2: Reference Figure 1-4 Based on the same concept as in Embodiment 1 above, this embodiment further proposes that a recessed groove 12 is provided on the outer side of the outer shell 2. The recessed groove 12 can provide installation space for internal components and reduce the overall area occupied by the outer shell 2. A fixing block 14 is fixedly connected to its inner wall side. The fixing block 14 can enhance the stability of the connection structure and provide reliable support for subsequent component installation. A torsion rod 13 is provided on the outer side of the fixing block 14. The torsion rod 13 is easy for the operator to hold and apply force. A screw 15 is fixedly connected to one end of the torsion rod 13. The screw 15 can be tightened or separated from the corresponding component by rotation. The outer side of the fixing plate 1 has a groove corresponding to the screw 15. The threaded hole, which mates with the screw 15, enables a detachable connection between the fixing plate 1 and the outer shell 2, facilitating component assembly and maintenance. A sealing strip is provided between two adjacent outer shells 2, which fills gaps and effectively prevents dust, moisture, and other impurities from entering the interior, improving overall sealing. The outer side of the outer shell 2 is coated with an epoxy resin coating, which enhances the corrosion resistance and wear resistance of the outer shell 2, extending its service life. A thermally conductive silicone grease layer is provided on the inner wall of the heat dissipation hole 5, which reduces heat transfer resistance and accelerates the dissipation of heat from the interior through the heat dissipation hole 5, improving heat dissipation efficiency.

[0021] The working principle of this utility model is as follows: Dragging the torsion rod 13 drives the screw 15 to rotate and connect with the corresponding threaded hole, installing the outer shell 2 and the fixing plate 1, splicing and installing multiple outer shells 2, setting up the heat dissipation plate 3 to conduct heat to the motor body, setting up multiple phase change capsules 7, the phase change material melts to quickly absorb heat, and conducts heat out through the other end of the heat dissipation plate 3, and setting up multiple heat dissipation holes 5 to enhance the heat dissipation effect of the heat dissipation plate 3, setting up multiple heat dissipation fins 9 to conduct heat to the motor, controlling the heat dissipation fan inside the heat dissipation shell 4 to enhance the heat dissipation effect of the heat dissipation fins 9, and setting up the fixing ring 10 to further limit and fix the multiple outer shells 2.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
