Description

Technical Field

[0001] This utility model relates to the field of motor grounding technology, and in particular to a motor grounding structure and a motor. Background Technology

[0002] Grounding refers to the connection between the neutral point of a power system and electrical installations, the exposed conductive parts of electrical equipment, and the external conductive parts of the installations, and the earth via a conductor. It can be divided into functional grounding, lightning protection grounding, and protective grounding.

[0003] Grounding is an effective component for dispersing static electricity in electrical equipment, and the overall grounding process is simple to complete. However, when installing grounding components for motors in electrical equipment, the grounding configuration must be set according to the motor's placement and specifications. Motors are driven by electricity for a long time, and static electricity is constantly generated. However, existing grounding technologies only transmit static electricity through conductive components and leads, which reduces the service life of the grounding structure and thus reduces conductivity.

[0004] To address this, we designed a motor grounding structure and a motor. Utility Model Content

[0005] The purpose of this utility model is to propose a motor grounding structure and a motor to solve the problem of poor electrical conductivity caused by the rudimentary structure of existing technologies.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A motor grounding structure includes a cylindrical body, on which multiple grooves are formed, and inside which a circular groove is formed, a first fixing body is provided in the circular groove, and a resistive layer is provided at the bottom of the cylindrical body.

[0008] The circular groove is provided with a dispersion ring for dispersing static electricity, the cylinder is provided with a first transmission rod for guiding static electricity, and the bottom of the cylinder is provided with multiple insertion angles.

[0009] Preferably, the cylinder is cylindrical in shape, and the cylinder port is provided with a rubber layer, which is fixedly connected to the outer wall of the cylinder.

[0010] Preferably, the first fixing body is fixedly connected to the inner wall of the circular groove, the dispersion ring is adapted to the first fixing body, and the dispersion ring is fixedly connected to the circular groove.

[0011] Preferably, the groove is provided with a plurality of rubber sleeves for reducing static current outflow, and the rubber sleeves are fixedly connected to the inner wall of the groove. The rubber sleeves are provided with a concentrator for concentrating static electricity, and the concentrator is fixedly connected to the rubber sleeve. One end of the first transmission rod is fixedly connected to the concentrator, and the other end is fixedly connected to the dispersion ring.

[0012] Preferably, the cylinder is provided with multiple transfer rings, and the transfer rings are fixedly connected to the cylinder. The concentrator is fixedly connected to the transfer rings through a second fixing body.

[0013] Preferably, the second fixing body is fixedly connected to the concentrator, and the second fixing body is fixedly connected to the cylinder by rubber rivets. The second fixing body is provided with a first conductive body for connecting the transmission ring. The first conductive body is provided with a dispersing rod, and one end of the dispersing rod is fixedly connected to the transmission ring through the second conductive body.

[0014] Preferably, the insertion angle is fixedly connected to the cylinder body, and a second transmission rod for connecting the transmission ring is provided on the insertion angle, and the bottom of the second transmission rod is pointed. The second transmission rod is fixedly connected to the insertion angle.

[0015] Preferably, the first fixing body is provided with a motor body, and the motor body is fixedly connected to the first fixing body.

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

[0017] 1. This utility model, through the setting of a concentrator and a transfer ring, ensures that the static electricity generated by the motor body is concentrated by the concentrator after the motor body is connected to the first fixed body, thereby reducing the static electricity content of the cylinder itself. The rubber sleeve set on the concentrator can effectively reduce the effect of static electricity returning to the cylinder, thereby improving the safety of the cylinder itself. The transfer ring can effectively reduce the phenomenon of static electricity retention. Compared with the prior art, the insertion angle set by the cylinder can improve the overall strength in the soil, thereby improving the service life and conductivity efficiency.

[0018] 2. By setting up the first and second transmission rods, this utility model ensures that the dispersion ring and the concentrator are always suspended, while ensuring the stability of static electricity during transmission. It also prevents the static electricity on the first transmission rod from coming into contact with other components and causing current diversion, thereby improving the efficiency of static electricity transmission. The setting of the second transmission rod at the insertion angle can improve the collection of a small amount of static electricity on the cylinder and the static electricity of the motor body, and then discharge them uniformly into the ground, thereby improving the conductivity efficiency.

Both ends of the first transmission rod 6 are fixedly connected to the concentrator 5 and the dispersion ring 4 by welding, which can effectively improve the service life and transmission efficiency.

[0028] The cylinder 1 is provided with multiple transfer rings 7. The transfer rings 7 are made of conductive material and mainly gather and guide the static electricity on the two concentrators 5. The transfer rings 7 are fixedly connected to the cylinder 1. The bottom of the transfer rings 7 is fixedly connected to the cylinder 1 by welding.

[0032] The working principle of this utility model is as follows:

[0033] When the motor body 2 is running, static electricity is generated due to friction and other reasons. This static electricity is first transferred to the first fixed body 3 through the motor body 2. The first fixed body 3 is connected to the dispersion ring 4 inside the cylinder 1. The dispersion ring 4 is made of conductive material and can effectively disperse the static electricity from the first fixed body 3. The dispersed static electricity is then transferred to the concentrator 5 through the first transmission rod 6. The concentrator 5 is located on a rubber sleeve and is used to concentrate the static electricity and reduce the static electricity retention rate on the side wall of the cylinder 1. The concentrated static electricity is guided to the transmission ring 7. The transmission ring 7 is also made of conductive material and can gather and guide the static electricity on the two concentrators 5. A dispersion rod 13 is provided on the transmission ring 7 to balance the static electricity value on the transmission ring 7 and ensure the uniform distribution of static electricity. The balanced static electricity is transferred to the insertion angle 8 through the second transmission rod 9. The insertion angle 8 is inserted into the ground to release the static electricity to the ground, thereby completing the static grounding process.
