[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it 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 directly connected, or indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] Example: See Figure 1-Figure 8 A mining PCB stator axial flux variable frequency speed regulation integrated motor includes a connecting tube 1 connected to a motor body, an inner wall of the connecting tube 1 is provided with a discharge component 2, and the humid gas inside the motor is discharged through the discharge component 2.

[0025] In this solution, the connecting tube 1 is connected to the motor body, so that the moisture in the inner cavity of the motor is discharged through the connecting tube 1, and the discharge component 2 accelerates the discharge of the gas in the inner cavity of the motor.

[0026] Furthermore, the discharge assembly 2 includes a driving member 21 connected to the connecting tube 1, and the output end of the driving member 21 passes through and extends to the inner cavity of the connecting tube 1. A crankshaft 22 is provided at the output end of the driving member 21, and a push rod 23 is rotatably installed on the outer surface of the crankshaft 22.

[0027] In this embodiment, the driving member 21 is a device with power output such as a motor, and is connected to an external control device. When the driving member 21 is started, it synchronously drives the crankshaft 22 disposed at its output end to rotate. At the same time, the driving member 21 can also be a manual turntable, and the crankshaft 22 is driven to rotate by rotating the turntable.

[0028] Furthermore, a first extrusion block 261 is provided at one end of the push rod 23 away from the crankshaft 22, and a movable plate 24 is provided at the end of the first extrusion block 261. At the same time, a slide groove 241 is penetrated through one side of the movable plate 24, and the inner wall of the slide groove 241 is slidably connected to the outer surface of the crankshaft 22. A second extrusion block 271 is provided at one end of the movable plate 24 away from the first extrusion block 261.

[0029] Specifically, when the crankshaft 22 rotates, the movable plate 24 installed on the outer surface is synchronously driven to move. Since the end of the movable plate 24 is rotatably connected to the end of the first extrusion block 261, the first extrusion block 261 moves along the slide groove 241, thereby pushing the gas.

[0030] When the first extrusion block 261 moves, the movable plate 24 drives the second extrusion block 271 to move. At the same time, the movable plate 24 is limited by the slide groove 241 on the outer surface of the movable plate 24 and the crankshaft 22, so that the movable plate 24 remains stable as a whole when moving.

[0031] Furthermore, a first ring 26 and a second ring 27 are respectively provided at both ends of the inner wall of the connecting tube 1, and the inner walls of the first ring 26 and the second ring 27 are inclined. At the same time, the inner wall of the first ring 26 is slidably connected to the outer surface of the first extrusion block 261, and the inner wall of the second ring 27 is slidably connected to the outer surface of the second extrusion block 271.

[0032] Specifically, since the inner walls of the first ring 26 and the second ring 27 are inclined, and the second extrusion block 271 moves, a certain gap is reserved between the second extrusion block 271 and the inner wall of the second ring 27, so that the gas in the motor cavity is discharged through the second extrusion block 271.

[0033] Furthermore, a driving rod 25 is provided on the outer surface of the crankshaft 22 and on one side of the push rod 23 , and a through hole 28 is opened at the end of the second collar 27 , and the inner wall of the through hole 28 is slidably connected to the outer surface of the end of the driving rod 25 .

[0034] Specifically, when the crankshaft 22 rotates, the driving rod 25 is synchronously driven to move, thereby squeezing the gas inside the motor through the through hole 28, causing the gas inside to move.

[0035] Furthermore, rubber blocks 29 are disposed on the outer surfaces of the first extrusion block 261 and the second extrusion block 271 , and the outer surfaces of the rubber blocks 29 are in contact with the inner walls of the first ring 26 and the second ring 27 .

[0036] Specifically, the inner walls of the first sleeve ring 26 and the second sleeve ring 27 are sealed by the rubber block 29 disposed on the outer surfaces of the first extrusion block 261 and the second extrusion block 271, so that the first extrusion block 261 and the second extrusion block 271 push the moisture inside the motor.

[0037] When the second extrusion block 271 moves to the middle position, the moisture inside the motor is absorbed into the inner cavity of the connecting tube 1. Since the first extrusion block 261 and the second extrusion block 271 are connected by the movable plate 24, when the second extrusion block 271 is separated from the second ring 27, the first extrusion block 261 fits against the inner wall of the first ring 26, thereby reciprocatingly discharging the moisture in the inner cavity of the motor.

[0038] Furthermore, the protection component 3 is assembled at one end of the connecting tube 1, and the protection component 3 is connected to the connecting tube 1, and the inside and outside of the motor body are divided by the protection component 3. The protection component 3 includes a fixed tube 31 connected to the connecting tube 1, and a power ring 32 is slidably mounted on the inner wall of the fixed tube 31, and the outer surface of the power ring 32 penetrates and extends to the outside of the fixed tube 31.

[0039] In this embodiment, when the power ring 32 rotates, the first rotating block 33 arranged at its end is driven to rotate. At the same time, the outer surface of the power ring 32 is arranged outside the fixed cylinder 31, so as to facilitate the driving of the power ring 32. At the same time, a micro motor can also be arranged at the end of the power ring 32, and the power ring 32 is driven by the micro motor to reciprocate until it reaches the optimal position.

[0040] Furthermore, a first rotating block 33 is disposed at the end of the power ring 32, and a plurality of groups of positioning rods 331 are evenly disposed on the outer surface of the first rotating block 33. A movable rod 35 is rotatably mounted at the end of the positioning rod 331.

[0041] Specifically, when the first rotating block 33 rotates, the positioning rod 331 rotatably mounted on the outer surface thereof is driven to move. Since the end of the positioning rod 331 is connected to the movable rod 35 , the movable rod 35 moves along with the positioning rod 331 .

[0042] Furthermore, a second rotating block 34 is disposed at the end of the first rotating block 33, and the outer surface of the second rotating block 34 is connected to the inner wall of the fixed cylinder 31. A limiting rod 341 corresponding to the positioning rod 331 is disposed on the outer surface of the second rotating block 34, and the end of the limiting rod 341 is rotatably connected to the outer surface of the movable rod 35.

[0043] Specifically, since the limiting rod 341 is rotatably mounted on the outer surface of the second rotating block 34 , and the end of the limiting rod 341 is rotatably connected to the outer surface of the movable rod 35 , the movable trajectory of the movable rod 35 is limited.

[0044] Furthermore, an annular block 38 is slidably mounted on the end of the fixed cylinder 31, and one end of the annular block 38 close to the second rotating block 34 is inclined. A slider 36 is rotatably mounted on the end of the movable rod 35, and the end of the slider 36 is slidably connected to the end of the annular block 38.

[0045] Specifically, a guide groove corresponding to the slider 36 is provided at the end of the annular block 38, and the inner wall of the guide groove is slidably connected to the outer surface of the slider 36, thereby limiting the operating state of the slider 36, so that when the slider 36 moves outward, it pushes the annular block 38 to move, wherein a telescopic rod is provided at the end of the annular block 38, and the end of the telescopic rod is connected to the inner wall of the fixed cylinder 31, thereby creating a gap between the annular block 38 and the fixed cylinder 31, which is convenient for discharging the gas in the inner cavity of the motor.

[0046] Furthermore, a baffle 37 is provided at a middle position of the second rotating block 34 away from one end of the first rotating block 33 , and an outer surface of the baffle 37 is in contact with an inner wall of the annular block 38 .

[0047] Specifically, when the annular block 38 moves, its middle portion is separated from the baffle 37, thereby creating a gap between the baffle 37 and the annular block 38, thereby accelerating the speed of exhausting the gas from the inner cavity of the motor. At the same time, the outer surfaces of the annular block 38 and the baffle 37 are provided with rubber or other sealing components, so that when not in use, the whole remains sealed, reducing the entry of external moisture or dust, thereby extending the service life of the motor.

[0048] The control device can select a single-chip microcomputer as the control end. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (Micro controller unit), which is composed of an arithmetic unit, a controller, a memory, an input and output device, etc., which is equivalent to a microcomputer. Compared with the general-purpose microprocessor used in personal computers, it emphasizes self-supply (no external hardware) and cost saving. Its biggest advantage is that it is small in size and can be placed inside the instrument, but it has a small storage capacity, a simple input and output interface, and low functional consumption.

[0049] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
