Description

Technical Field

[0001] This utility model belongs to the field of motor technology, specifically relating to a waterproof motor. Background Technology

[0002] Fiberglass cloth is a geosynthetic material made primarily of glass fiber, combined with short-fiber needle-punched nonwoven fabric and other materials. Based on its alkali content, it is classified into three types: high-alkali cloth, medium-alkali cloth, and alkali-free cloth, suitable for applications such as optical fiber, building materials, and circuit board manufacturing, respectively. Its glass fiber layers, through an interwoven structure, impart high strength and corrosion resistance to the material, with the single filament diameter typically controlled within the 4-10 micrometer range to ensure process feasibility.

[0003] In existing fiberglass cloth production, glass is first melted, then drawn into fibers through a mold. A motor and reducer drive a winding roller to wind the fibers. During winding, cooling water is sprayed onto the fibers to cool them quickly and shape them. However, the cooling water sprayed onto the motor and reducer is corrosive. If the motor and reducer are exposed to corrosive cooling water for a long time, the seals are prone to corrosion, and water can easily enter the motor or reducer, causing the motor to burn out and the reducer to be damaged. Once the motor or reducer is damaged, it requires shutdown for repair, reducing production efficiency and wasting time, while replacement costs are high. Summary of the Invention

[0004] To address the problems mentioned in the background section, the purpose of this invention is to provide a waterproof motor.

[0005] This utility model discloses a waterproof motor, comprising a housing, a copper rotor, a stator, a rear cover, a rear sealing ring, a first front sealing ring, a second front sealing ring, and a water-throwing block. The stator is fixedly connected inside the housing, and the copper rotor is rotatably connected inside the stator. The front side of the copper rotor's shaft is fixedly connected to a mounting groove on the front side of the housing via a bearing, and the rear end of the copper rotor's shaft is fixedly connected to a mounting groove inside the rear cover via a bearing. A rear sealing ring is connected to the outer wall of the rear cover, and the rear cover is fixedly connected to the rear end of the housing via bolts. The rear sealing ring is sealed to both the rear cover and the housing. The first and second front sealing rings of the copper rotor are respectively installed on the inner front side of the housing, and are sealed to the shaft of the copper rotor. The shaft of the copper rotor extends outside the housing. The water-throwing block is fixedly connected to the front side of the copper rotor's shaft and is located at the outer front end of the housing.

[0006] As a preferred embodiment, the outer casing is made of stainless steel and has a fixing threaded hole.

[0007] As a preferred option, the back cover is a stainless steel back cover.

[0008] As a preferred embodiment, the rear sealing ring, front sealing ring one, and front sealing ring two are corrosion-resistant and high-temperature resistant sealing rings.

[0009] Compared with existing technologies, the beneficial effects of this utility model are as follows: Waterproofing and water-dissipating are achieved through the coordinated action of the outer shell, copper rotor, stator, rear cover, rear sealing ring, front sealing ring one, front sealing ring two, and water-dissipating block, making it less likely for water to splash onto the motor and preventing water from entering the motor, thus extending its service life. Specific advantages include: I. This utility model achieves water ejection from the motor by using a water-spinning block. When cooling water is sprayed, the water-spinning block rotates and throws the water away, making it difficult for water to enter the motor and preventing the motor from burning out.

[0010] Second, this utility model uses a copper rotor for driving, which makes it small in size and high in power, with a power of up to 264W. It does not require a speed reducer and can directly drive the winding roller.

[0011] Third, this utility model achieves the sealing of the rear cover through the rear sealing ring, while the front sealing ring one and the front sealing ring two can achieve the sealing of the front end of the copper rotor and the front end of the outer shell, thus achieving secondary sealing and improving the sealing performance.

[0012] IV. This utility model uses a stainless steel outer shell and a stainless steel back cover to improve corrosion resistance and also to dissipate heat quickly. Attached Figure Description

Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0017] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0018] Combination Figure 1 The following is a description of this specific embodiment, which adopts the following technical solution: It includes a housing 1, a copper rotor 2, a stator 3, a rear cover 4, a rear sealing ring 5, a first front sealing ring 6, a second front sealing ring 7, and a water-spinning block 8. The stator 3 is fixedly connected inside the housing 1, and the copper rotor 2 is rotatably connected inside the stator 3. The copper rotor 2 can rotate within the stator 3. The copper rotor 2 is a rotor with embedded copper plates, and it has high power, reaching 264W. During use, no speed reducer is needed. The front side of the shaft of the copper rotor 2 is fixedly connected to the mounting groove on the front side of the housing 1 via a bearing, and the rear end of the shaft of the copper rotor 2 is fixedly connected to the mounting groove inside the rear cover 4 via a bearing. A rear sealing ring 5 is connected to the outer wall of the rear cover 4. The rear sealing ring 5 is fixedly connected to the rear end of the outer casing 1 by bolts. It is sealed to the rear cover 4 and the outer casing 1 respectively. The rear sealing ring 5 can seal the rear cover 4. The front sealing ring 6 and the front sealing ring 7 of the copper rotor 2 are installed on the inner front side of the outer casing 1 respectively. The front sealing ring 6 and the front sealing ring 7 are sealed to the shaft of the copper rotor 2 respectively. The front sealing ring 6 and the front sealing ring 7 can achieve secondary sealing with the front end of the outer casing 1, so that water is not easy to enter the interior of the outer casing 1. The shaft of the copper rotor 2 extends out of the outer casing 1. The water-throwing block 8 is fixedly connected to the front side of the shaft of the copper rotor 2 and is located at the outer front end of the outer casing 1. The water-throwing block 8 can be used to throw away the cooling water by the rotation of the copper rotor 2, so that water is not easy to enter the motor.

[0019] In this specific embodiment, the outer shell 1 is a stainless steel shell with a fixed threaded hole. The rear cover 4 is a stainless steel rear cover. The use of stainless steel for the outer shell and rear cover enables corrosion resistance and rapid heat dissipation. The rear sealing ring 5, the first front sealing ring 6, and the second front sealing ring 7 are corrosion-resistant and high-temperature resistant sealing rings. The sealing rings can improve wear resistance and facilitate improved sealing performance.

[0020] The working principle of this specific embodiment is as follows: During use, the fixing threaded hole on the outer shell 1 can achieve quick fixation, and the rotating shaft of the copper rotor 2 can be connected to the shaft of the winding roller. The winding roller is directly driven by the motor. The copper rotor 2 can reduce its size, while the power can reach 264W. There is no need to use the existing reducer, thus reducing costs. During use, the copper rotor 2 will drive the water-throwing block 8 to rotate. The water-throwing block 8 can throw off the water at the front of the motor, making it difficult for water to enter the motor. The front of the motor uses front sealing ring 1 6 and front sealing ring 2 7 to achieve secondary sealing at the front of the outer shell, which improves the sealing performance. After secondary sealing, water is not easy to enter the motor, which can extend the service life of the motor. At the same time, the motor is controlled by PLC to achieve stable control of the motor rotation, which is convenient for control.
