Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a protection device for motors. Background Art

[0002] In the textile industry, it is necessary to use a cotton opener to evenly disperse and fluff cotton bodies such as hollow cotton. This process is essential. However, during the operation of the cotton opener, a small amount of fluffy cotton flocs will escape, resulting in a large amount of flocs accumulating on the motor of the cotton opener after long-term operation. The above situation is inconvenient to clean, and the flocs are easy to block the motor heat dissipation components, resulting in faults such as the motor overheating and self-stopping or short-circuiting, which greatly affects the production efficiency.

[0003] In summary, in the textile environment, it is impossible to avoid the escape of flocs, and the flocs have an impact on the normal operation of the motor. Therefore, it is considered to design a protection device outside the motor to prevent the flocs from blocking the motor heat dissipation components. In view of this, we propose a protection device for the motor. Summary of the Utility Model

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1-5 , the following embodiments are used to elaborate the above technical solutions of the present utility model:

[0027] A protective device for a motor, used for external protection of the motor body 1. The protective device includes:

[0028] Two symmetrically arranged protective sleeve assemblies 2, as shown in the structures of Figure 1 and Figure 3 . It includes two semi-sleeves 21 detachably installed outside the motor body 1. The semi-sleeve 21 is provided with a circulation hole 211, and the inner wall of the semi-sleeve 21 is provided with heat-conducting fins 25 for absorbing the heat of the motor body 1. In this embodiment, in order to better take away the heat of the heat-conducting fins 25 through the circulating air flow, the heat-conducting fins 25 are arranged in a ring along the axis of the semi-sleeve 21, and the circulation hole 211 is arranged between two adjacent heat-conducting fins 25.

[0029] As shown in the structure of Figure 4 . In this embodiment, a limit block 23 is provided on the outer wall of the semi-sleeve 21, and an insertion groove 231 is provided on the limit block 23. The filter screen 26 is inserted into the insertion groove 231, which can facilitate the filtering of floc impurities. At the same time, the method of inserting and installing the filter screen 26 is convenient and efficient, and it can be quickly replaced after the filter screen filters the flocs.

[0030] As shown in the structures of Figure 1 , Figure 5 . The heat dissipation unit 3 includes an end cover 31 installed at one end of the two protective sleeve assemblies 2. A heat dissipation fan 33 is installed in the end cover 31. For the convenience of installation, in this embodiment, semi-circular plates 24 are fixedly installed at both ends of the semi-sleeve 21. The end cover 31 is provided with a flange 312 for detachably installing at the semi-circular plate 24. The end cover 31 is provided with an exhaust hole 311, and the heat dissipation fan 33 is detachably installed in the end cover 31 through a mounting bracket 32.

[0031] It should be noted that, in order to ensure the air flow and maintain a good heat dissipation effect, the motor body 1 is installed as shown in Figure 2 , but it will not block the connection port between the end cover 31 and the semi-sleeve 21, so that it can obtain an air circulation path.

[0032] The protection device of this embodiment has the following working principle: Close the two half sleeves 21 that can be clamped outside the motor body 1, and form a closed sleeve structure after fixing with screws at the side convex plates 22. In order to maintain a good clamping effect, a rubber cushion layer is provided at the joint surface between the half ring plate 24 and the motor body 1, and finally the heat dissipation unit 3 is installed. During operation, the flocs will be retained by the filter screen 26 and mainly accumulate on the upper part at this time, so ventilation will not be affected. The heat conduction fins 25 absorb the heat of the motor body 1, and the flowing air can take away the heat of the heat conduction fins 25 and the motor body 1, achieving good heat dissipation effect while avoiding floc blockage, without affecting continuous operation, and it is relatively convenient to replace the filter screen 26.

[0033] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0034] In addition, if there are descriptions such as "first", "second", etc. involved in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first", "second" may explicitly or implicitly include at least one such feature. In addition, "multiple" means more than two. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those skilled in the art can implement it. When the combination of technical solutions conflicts with each other or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0035] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended to include all changes falling within the meaning and scope of the equivalent elements of the claims in the present invention.
