[0002] The motor of the flameproof gear reducer is a type of motor. The motor is a device that converts electrical energy into mechanical energy. The motor of the flameproof gear reducer is specially designed and manufactured based on the ordinary motor to make it have a flameproof function. The motor of the flameproof gear reducer can operate safely in flammable, explosive and other dangerous environments to prevent explosions caused by sparks or high temperatures. The gear reducer is used to achieve the effect of reducing speed and increasing torque.
[0003] During the use of the motor of the flameproof gear reducer, a rotating shaft is usually used to drive a fan to rotate, and then the hot air driven by the fan is discharged through the heat dissipation duct. When the heat dissipation duct is used, due to its special working environment, the heat dissipation duct hole on the motor is often small, so as to reduce the contact between the inside of the motor and the surrounding environment when the motor stops working, and prevent the surrounding flammable substances from entering the motor through the heat dissipation hole (6) and adhering to its internal structure. Then, when the motor is energized, it reacts with the flammable substances and causes an explosion. However, the relatively narrow heat dissipation duct is extremely unfavorable for the heat dissipation inside the motor.

DETAILED DESCRIPTION
[0021] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0022] like Figure 1-Figure 5 As shown, the motor based on the flameproof gear reducer provided in the present embodiment includes a motor housing 1 on which a rear end heat dissipation component 2 is fixedly installed, and a hood member 3 fixedly installed on the motor housing 1, the rear end heat dissipation component 2 is used to dissipate heat and cool the motor, and a telescopic structure component 4 is fixedly connected inside the hood member 3, and a movable sealing plate 5 is provided on the telescopic structure component 4, and a heat dissipation hole 6 is opened on the hood member 3, and the telescopic structure component 4 adjusts the connection and closing of the heat dissipation hole 6 by controlling the movement of the movable sealing plate 5. When the motor is in use, the motor is cooled by the rear end heat dissipation component 2. Before this, the movable sealing plate 5 is driven away from the heat dissipation hole 6 by using the telescopic structure component 4. At this time, the heat dissipation hole 6 connects the outside of the motor with the inside of the hood member 3, and the rear end heat dissipation component 2 discharges the heat inside the motor to the outside of the motor through the heat dissipation hole 6. When the motor is not in use, the telescopic structure component 4 is controlled to move the movable sealing plate 5 toward the heat dissipation hole 6, so that the movable sealing plate 5 contacts the heat dissipation hole 6, and the heat dissipation hole 6 is closed. At this time, the inside of the motor is no longer connected to the outside, so that the dust in the surrounding environment of the motor no longer enters the inside of the motor.
[0023] Among them, Figure 5As shown, the rear end heat dissipation component 2 includes a rear end cover 201, an outer cover 202 and a fan blade 203. The rear end cover 201 is fixedly connected to the inner wall of one end of the outer shell, the outer cover 202 is fixedly connected to one side of the rear end cover 201, and the fan blade 203 is rotatably connected to the side of the outer cover 202 away from the rear end cover 201. The rear end heat dissipation component 2 is an existing structure of the motor, which is used to convect the air inside and outside the motor through the rotation of the fan blade 203, and then discharge the heat dissipated from the motor itself to the outside of the motor, so as to achieve the purpose of cooling the motor.
[0024] Further, such as Figure 4 as well as Figure 5 As shown, the telescopic structure assembly 4 includes a supporting and fixing frame 401, a motor fixing slot plate 402, a limiting frame 403, a threaded rod 405, a movable connecting frame 406 and a motor 1 404. The supporting and fixing frame 401 is fixedly connected to the inner wall of the motor housing 1, the motor fixing slot plate 402 is fixedly connected to the supporting and fixing frame 401, the motor 1 404 is fixedly connected to the motor fixing slot plate 402, the limiting frame 403 is fixedly connected to the motor fixing slot plate 402, one end of the threaded rod 405 is connected to the output end of the motor 1 404, the movable connecting frame 406 is threadedly connected to the threaded rod 405, the movable connecting frame 406 is slidably connected to the limiting frame 403, and the threaded rod 405 is rotatably connected to the limiting frame 403. When the threaded rod 405 rotates, under the action of the limit frame 403, it is ensured that the threaded rod 405 is more stable and reliable when rotating. When the telescopic structure component 4 is in use, the motor 404 is started, thereby driving the threaded rod 405 to rotate. When the threaded rod 405 rotates, it will drive the movable connecting frame 406 to move, and when moving, it will drive the movable sealing plate 5 fixedly connected to the movable connecting frame 406 to move. When the movable sealing plate 5 is away from the heat dissipation hole 6, the heat dissipation hole 6 is in a connected state. When the movable sealing plate 5 contacts the heat dissipation hole 6, the heat dissipation hole 6 is in a closed state, thereby making the motor in a closed state, avoiding the adhesion of flammable substances or dust in the surrounding air;
[0025] The movable connecting frame 406 is fixedly connected to the side surface of the movable sealing plate 5. A circular hole 7 is opened on the movable sealing plate 5. The circular hole 7 corresponds to the position of the threaded rod 405. When the movable connecting frame 406 moves on the threaded rod 405, the end of the threaded rod 405 close to the movable connecting frame 406 will move toward the circular hole 7 when the movable connecting frame 406 continues to move toward the direction of the motor 404, so as to avoid the threaded rod 405 from conflicting with the movable sealing plate 5. The movable sealing plate 5 and the heat dissipation hole 6 are misaligned, so that when the two are in contact, the sealing effect is more obvious.
[0026] Finally, if Figure 4As shown, a protective member 8 is fixedly connected to one end of the wind shield member 3 away from the motor housing 1, and the protective member 8 is used to protect the heat dissipation hole 6 to prevent the heat dissipation hole 6 from being squeezed by external objects and deformed, thereby causing loose contact between the heat dissipation hole 6 and the movable sealing plate 5.
[0027] like Figure 1-Figure 5 As shown, the principle of the motor based on the flameproof gear reducer provided in this embodiment is as follows: when in use, the motor is cooled by the rear end heat dissipation component 2. Before this, by starting the motor 404, the threaded rod 405 is driven to rotate. When the threaded rod 405 rotates, it will drive the movable connecting frame 406 to move, and when moving, it will drive the movable sealing plate 5 fixedly connected to the movable connecting frame 406 to move. When the movable sealing plate 5 is away from the heat dissipation hole 6, the heat dissipation hole 6 is in a connected state. At this time, the heat dissipation hole 6 connects the outside of the motor with the inside of the wind cover part 3, and the rear end heat dissipation component 2 discharges the heat inside the motor to the outside of the motor through the heat dissipation hole 6. When the motor is not in use, the telescopic structure component 4 is controlled to move the movable sealing plate 5 toward the heat dissipation hole 6, so that the movable sealing plate 5 contacts the heat dissipation hole 6 and closes the heat dissipation hole 6. At this time, the inside of the motor is no longer connected to the outside, and the heat dissipation hole 6 is in a closed state, so that dust in the surrounding environment of the motor no longer enters the inside of the motor.
[0028] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.
[0029] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.
