Description

Technical Field

[0002] A motor is a device that converts electrical energy into mechanical energy, usually consisting of a stator, rotor, brushes, bearings, casing, etc. The motor uses the interaction of electric current in a magnetic field to generate force or torque, thereby driving the machine to operate. The motor needs to use a protective safety structure so that it can be used normally in harsh environments.

[0003] At present, there are still some shortcomings in the motor, such as the inconvenience of motor heat dissipation:

[0004] In order to overcome the low heat dissipation efficiency of the motor, a Chinese patent of the prior art (publication number: CN218586986U) discloses a motor with good safety protection, which is provided with a protection mechanism to solve the problem that when a fault occurs during the operation of the motor and maintenance is required, the protection device is sealed and it is inconvenient to repair the motor.

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.

[0039] Embodiment 1:

[0040] like Figure 1-Figure 5The technical solution shown in the figure, the present invention provides the following technical solution: In order to solve the problem that the motor is easily corroded by moisture and affects the service life and safety, a moisture absorption mechanism is disclosed:

[0041] The protective shell 1 includes a cover 2 connected to the upper surface of the protective shell 1, an output device 3 is installed inside the protective shell 1, a through groove 101 is formed on the side of the protective shell 1 away from the output device 3, a through hole is formed on the side of the protective shell 1 close to the output device 3, an output end of the output device 3 is formed through the through hole, two groups of through grooves 101 are formed symmetrically about the center of the protective shell 1, a sealing ring 102 is connected inside the through groove 101, a rotating box 103 is fitted inside the sealing ring 102, a desiccant is embedded inside the rotating box 103, the rotating box 103 rotates inside the through groove 101 through the sealing ring 102, and a dehumidifier is provided inside the through groove 101 to reduce the moisture inside the motor Structure, the protective shell 1 is symmetrically provided with a guide groove 108 at the center thereof, a rotating mechanism for adjusting the position of the motor is provided inside the protective shell 1, a movable groove 116 is symmetrically provided on the outer side of the protective shell 1, a locking mechanism for improving the moving efficiency of the motor is provided inside the movable groove 116, the moisture absorption mechanism includes a rotating block 104, the rotating block 104 is fixed on the top of the rotating box 103, the rotating block 104 rotates inside the through groove 101, the through groove 101 is symmetrically provided with a positioning groove 105 on the side close to the rotating block 104, the rotating block 104 is symmetrically provided with a first telescopic groove 106 on the inner side thereof, a positioning ball 107 is connected inside the first telescopic groove 106, and a spring is connected between the positioning ball 107 and the first telescopic groove 106;

[0042] Before using the motor, the cover 2 needs to be opened, and then the output device 3 is installed to the specified position inside the protective shell 1, and then the output end of the output device 3 is exposed through the through hole of the protective shell 1, and then the output device 3 is used, wherein the heat dissipation device 4 can reduce the temperature of the output device 3 during operation by air cooling, and the protective shell 1 can improve the surface protection strength of the output device 3. Due to environmental influences such as rain, moisture is easily generated inside the protective shell 1. When the moisture enters the protective shell 1 through the heat dissipation port, it will be absorbed by the desiccant inside the rotating box 103. The desiccant can keep the inside of the protective shell 1 dry, thereby preventing moisture from corroding the output device 3.

At the same time, the desiccant can restore its own moisture absorption effect through light, thereby preventing the motor from being corroded and improving the protection safety of the motor in disguise.

[0043] Embodiment 2:

[0044] like Figure 2 , Figure 3 , Figure 6 and Figure 7 The technical solution shown in the figure, the present invention provides the following technical solution: In order to solve the problem that the protective shell 1 is not completely protective of the motor and is prone to collision, a rotating mechanism is disclosed:

The sliding groove 115 is opened on the outside of the protective shell 1;

[0046] When the motor is not in use or needs to be transported, the threaded rod 110 can be rotated through the protective shell 1 and the guide block 109. When the threaded rod 110 rotates, it can drive the guide block 109 to slide threadedly. When the guide block 109 slides threadedly, it can slide through the guide groove 108. When the guide block 109 slides, it can drive the output device 3 to move. When the output device 3 moves, the output end can move to the inside of the protective shell 1. At this time, the components of the output device 3 will be completely stored in the protective shell 1, which can prevent the output device 3 from being hit during transportation. When the output device 3 is stored in the protective shell 1, a through hole will be left on the side of the protective shell 1, and the screw When the rod 110 rotates, it can drive the small gear 111 to rotate. When the small gear 111 rotates, it can drive the large gear 112 to mesh and rotate. When the large gear 112 meshes and rotates, it can rotate through the protective shell 1. When the large gear 112 rotates, it can drive the sealing block 113 to rotate. When the sealing block 113 rotates, it can drive the sliding block 114 to rotate. When the sliding block 114 rotates, it can slide inside the sliding groove 115.

[0047] Embodiment three:

[0048] like Figure 1 , Figure 2 , Figure 8 , Fig. 9 and Fig.10 The technical solution shown in the figure, the present invention provides the following technical solution: In order to solve the problem that the motor is inconvenient to move and affects the efficiency of position change, a locking rotation mechanism is disclosed:

[0049] The engaging mechanism includes a support frame 117, which moves inside the movable groove 116. A roller 118 is symmetrically installed at the bottom of the support frame 117. A limiting block 119 is symmetrically fixed on one side of the support frame 117 close to the protective shell 1. The limiting block 119 penetrates and slides inside the limiting groove 120. The limiting groove 120 is symmetrically arranged on the side of the movable groove 116. A second telescopic groove 121 is penetrated and arranged on the side of the support frame 117. A locking block 122 slides through and slides inside the second telescopic groove 121 close to the protective shell 1. A pull rod 123 is fixed on the side of the locking block 122 away from the protective shell 1. The pull rod 123 penetrates and slides inside the second telescopic groove 121.

A first locking groove 124 and a second locking groove 125 are symmetrically arranged on the side of the movable groove 116 close to the limiting groove 120. The first locking groove 124 and the second locking groove 125 are symmetrically distributed up and down about the center of the movable groove 116.

[0050] When the motor needs to be moved, pulling the pull rod 123 can drive the locking block 122 to move. When the locking block 122 moves, it can slide through the second telescopic slot 121 and the first slot 124. When the locking block 122 slides, it can squeeze the spring. When the locking block 122 squeezes out of the first slot 124, it lifts one side of the protective shell 1 and pushes the support frame 117 downward. When the support frame 117 is pushed, it can drive the roller 118, the locking block 122 and the limit block 119 to move. When the limit block 119 moves, it can slide through the limit slot 120. When the limit block 119 slides, it can drive the locking block 122 to move to the second slot 125 On the side, at this time, the support frame 117 can drive the roller 118 to move to the bottom of the protective shell 1, and the pull rod 123 is released. Under the elastic force of the spring, the locking block 122 will reset, and the locking block 122 can be locked and positioned with the second slot 125 when it is reset. When one side of the protective shell 1 is lowered, the roller 118 can support the protective shell 1, and the roller 118 on the other side is lowered in the same way. The two rollers 118 can stably support the protective shell 1. At this time, the protective shell 1 can be pushed to roll on the ground through the roller 118, which improves the efficiency of carrying the protective shell 1, saves physical strength, and improves the convenience of using the motor.
