Description

Technical Field

[0001] This utility model relates to the field of motor protection structure technology, and in particular to a motor protection structure suitable for harsh environments. Background Technology

[0002] With the widespread adoption of factory automation, smart warehousing, and outdoor infrastructure (such as 5G base stations and photovoltaic inverters), the probability of equipment being exposed to harsh environments such as dust, rain, and oil has increased significantly. IP66 rating (dustproof and resistant to high-pressure water jets) has become a key technical indicator for ensuring the long-term reliability of equipment.

[0003] For example, existing mining motors need to withstand various dangerous environments such as rainstorms, high-pressure cleaning, and sand and gravel collisions, while also being robust and durable. Currently, existing motors do not have protective structures; the motor frame is simply exposed on the surface, which cannot meet the requirements for use in harsh environments. Utility Model Content

[0004] In response to the shortcomings of the existing production technology, the applicant provides a reasonably structured motor protection structure suitable for harsh environments. Through the unique design of the dust cover, the motor can be well protected, meeting the needs of use in harsh environments and extending the service life of the motor.

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

[0006] A motor protection structure suitable for harsh environments includes a motor base. A set of inverted "8" shaped front brackets is installed at the front end of the top surface of the motor base by a No. 1 fixing bolt. A set of inverted "8" shaped rear brackets is installed at the rear end of the top surface of the motor base by fasteners. Dust covers are installed on the top surfaces of the two front brackets and the two rear brackets by a No. 2 fixing bolt. A baffle is installed in the middle of the top surface of the dust covers by a No. 3 fixing bolt.

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

[0008] The structure of the dust cover is as follows: it includes a dust cover body, the cross-section of the dust cover body is arc-shaped, a square hole for installing a baffle is opened in the middle of the top surface of the dust cover body, oil injection holes are opened at both ends of the square hole, and a clearance groove is provided on one side of the dust cover body.

[0009] The size of the square hole is smaller than the size of the baffle.

[0010] The top surface of the motor base is equipped with a hanging bracket, and the mounting position of the hanging bracket corresponds to the square hole.

[0011] The single front bracket has a "7" shaped structure.

[0012] The top surface of each front bracket has a No. 1 fixing hole for connecting to the dust cover, and the bottom of the front bracket has a No. 1 elongated hole for fixing to the motor base.

[0013] The single rear support has a "[" structure.

[0014] The top surface of each rear bracket has a No. 2 fixing hole for connecting to the dust cover, and the bottom of the rear bracket has a No. 2 oblong hole for fixing to the motor base.

[0015] The dust cover, baffle, front bracket, and rear bracket are all made of stainless steel.

[0016] The beneficial effects of this utility model are as follows:

[0017] This utility model has a compact and reasonable structure and is easy to operate. Through the cooperation of components such as dust cover, baffle, front bracket and rear bracket, it can effectively protect the motor, meet the needs of use in harsh environments and extend the service life of the motor.

[0018] The protective structure described in this utility model can effectively improve the protection of the machine body, effectively reduce cleaning, facilitate long-term operation of the equipment, reduce the frequency of grease replacement, reduce the amount of water used for cleaning and the number of times fault repair is required, and increase the service life.

[0031] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0032] like Figures 1-8 As shown, the motor protection structure suitable for harsh environments in this embodiment includes a motor base 1. A set of inverted "V" shaped front brackets 7 are installed at the front end of the top surface of the motor base 1 by fixing bolt No. 1 6. A set of inverted "V" shaped rear brackets 8 are installed at the rear end of the top surface of the motor base 1 by fasteners. Dust covers 3 are installed on the top surfaces of the two front brackets 7 and the two rear brackets 8 by fixing bolt No. 2. A baffle 4 is installed at the middle of the top surface of the dust cover 3 by fixing bolt No. 3 5.

[0033] The structure of the dust cover 3 is as follows: it includes a dust cover body 301, the cross-section of the dust cover body 301 is arc-shaped, a square hole 302 for mounting a baffle 4 is opened in the middle of the top surface of the dust cover body 301, and oil filling holes 303 are opened at both ends of the square hole 302. The position of the oil filling holes 303 is convenient for adding grease. A clearance groove 304 is provided on one side of the dust cover body 301 to make way for the motor junction box for easy installation.

[0034] The size of the square hole 302 is smaller than the size of the baffle 4.

[0035] The top surface of the motor base 1 is equipped with a hanging bracket 9. The installation position of the hanging bracket 9 corresponds to the square hole 302. When the hanging bracket 9 is needed, the baffle 4 can be opened without affecting the use. When the hanging bracket 9 is not needed, the baffle 4 can be locked, making it flexible to use.

[0038] The single rear support 8 is in the shape of "[".

[0039] The top surface of a single rear bracket 8 has a second fixing hole 801 for connecting with the dust cover 3, and the bottom of the rear bracket 8 has a second elongated hole 802 for fixing with the motor base 1.

[0040] The baffle 4 is arc-shaped, and after the baffle 4 is installed on the dust cover 3, it matches its arc surface.

[0041] The dust cover 3, baffle 4, front bracket 7 and rear bracket 8 are all made of stainless steel.

[0042] In actual use, first fix two front brackets 7 and two rear brackets 8 on the motor base 1. In this embodiment, the two rear brackets 8 are installed on the outer cover of the motor base 1. After all four brackets are fixed, use fasteners to fix the dust cover 3 to the four brackets. Then, align the square hole 302 with the hanging bracket 9. Finally, install the baffle 4 at the square hole 302. The entire dust cover 3 can cover and protect the motor.

[0043] All components described in this utility model are made of stainless steel, which can effectively ensure strength.

[0044] This utility model is an IP66 protection structure suitable for harsh environments. In addition to ensuring the basic conditions such as heat dissipation and performance of the machine body, it strengthens the structural protection and completely places the machine body under the dust cover 3.
