[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. It has a wide range of applications and is used in any situation where electrical energy is needed to drive mechanical motion.

[0003] However, motors generate a lot of heat during operation, and the working environment can be dusty, causing the internal fans and filters to easily become clogged. This makes it difficult for the heat to dissipate. Manufacturers have therefore developed heat dissipation covers to protect the motor and dissipate heat. However, the motor generates noise during operation, affecting the working environment and consequently impacting worker efficiency. The heat dissipation cover contains a fan, and the noise generated by the fan and motor operating simultaneously will severely affect the working environment. Utility Model Content

[0007] In the aforementioned noise-reducing motor heat dissipation cover, the sound-absorbing plate has a through hole, a sound-dampening plate is installed in the through hole, and a retaining plate is provided on the sound-dampening plate.

[0008] In the aforementioned noise-reducing motor heat dissipation cover, the sound-dampening plate is configured in a V-shape, and sound-dampening holes are provided on the sound-dampening plate.

[0009] In the aforementioned noise-reducing motor heat dissipation cover, the fixing plate has an insert plate with a slot, the cover has a corresponding locking block, and a spring is installed between the locking block and the cover.

[0010] In the aforementioned noise-reducing motor heat dissipation cover, a limiting plate is installed on the cover, the sound-absorbing plate and the second filter screen are slidably connected to the cover, the sound-absorbing plate and the second filter screen are in contact with the limiting plate, and the limiting plate is in contact with the cover via bolts.

[0011] Compared with the prior art, the advantages of this utility model are as follows: a sound-absorbing plate is added to the outside of the cooling structure to remove the noise generated by the fan and motor; after the cooling cover and cooling plate are filled with cold water, the noise is reduced by the discontinuity of the medium through which the sound waves pass; and sound-absorbing cotton is installed at the ventilation holes of the cooling cover to remove the noise generated by the motor.

[0021] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0022] like Figures 1 to 8 As shown, this utility model can be implemented through the following embodiments: A noise-reducing motor heat dissipation cover includes a protective cover 1 and a motor 2. The protective cover 1 includes a cover 11 and a base 12. A cooling plate 3 is installed inside the base 12. A cooling cover 31 is installed on the cooling plate 3. Cold water 32 is filled into the cooling cover 31 and the cooling plate 3. The cover 11 is installed above the base 12. A noise reduction layer 4 is installed outside the cooling cover 31. The noise reduction layer 4 has a through groove 41. A fixing plate 715 is installed in the through groove 41. From the inside to the outside, the fixing plate 715 is installed with a fan 51, a sound-absorbing plate 6 and a filter 52. From the inside to the outside, the cover 11 is installed with a fan 111, a sound-absorbing plate 6 and a filter 112. A ventilation hole 311 is opened inside the cooling cover 311. Sound-absorbing cotton 7 is installed on the ventilation hole 311.

[0023] A noise reduction layer 4 is installed on the outside of the cooling cover 31 and the cooling plate 3 to facilitate the filtering of noise from the motor 2. The cooling water filling of the cooling cover 31 and the cooling plate 3 is used for the propagation of sound in the air, and the noise is weakened by utilizing the different waveforms of sound waves transmitted between gaseous and liquid substances. The sound-absorbing cotton 7 is used to block the ventilation holes 311 to improve the noise reduction performance. The outside of the fan 1 51 and the fan 2 111 is equipped with a sound-absorbing plate 6 to eliminate the noise emitted by the fan 1 51, the fan 2 111 and the motor 2.

[0024] like Figure 6 As shown, the ventilation hole 311 has fixing parts 312 at both ends, and fixing grooves 313 are formed in the fixing parts 312. The sound-absorbing cotton 7 is provided with a fixing plate 715, and a bolt 8 passes through the fixing plate 715 and the fixing parts 312. The bolt 8 is used to pass through the fixing plate 715 and the fixing parts 312, so that the connection between the sound-absorbing cotton 7 and the ventilation hole 311 is stable, and the sound-absorbing cotton 7 is prevented from vibrating in the ventilation hole 311, which would cause more noise.

[0025] like Figure 2 and Figure 7 As shown, the silencing plate 6 has a through hole 61, and a sound-dampening plate 9 is installed in the through hole 61. A retaining plate 91 is provided on the sound-dampening plate 9. The through hole 61 is used by the silencing plate 6 to disperse sound waves and reduce noise; the sound-dampening plate 9 is elastic, and it reduces noise by vibration, and it relies on its elasticity to fix itself in the through hole 61 by the retaining plate 91.

[0026] like Figure 2 and Figure 7 As shown, the sound-absorbing plate 9 is V-shaped, and a sound-absorbing hole 92 is provided on the sound-absorbing plate 9. The V-shaped sound-absorbing plate 9 provides elasticity, so that the sound-absorbing plate 9 will vibrate to absorb sound waves when it receives them, and cooperate with the locking plate 91 to lock itself into the through hole 61; the sound-absorbing hole 92 further disperses the sound waves and improves the noise reduction performance.

[0027] like Figure 1 Figure 3 , Figure 5 and Figure 8 As shown, a mounting plate 715 has an insert plate 53, and a slot 531 is provided on the insert plate 53. A corresponding locking block 10 is installed inside the cover 11, and a spring 101 is installed between the locking block 10 and the cover 11. The slot 531 cooperates with the locking block 10 to fix the mounting plate 715 and the cover 11, strengthening the connection between the cover 11 and the noise reduction layer 4, and facilitating the disassembly and replacement of the mounting plate 715, as well as the replacement and disassembly of the fan 51, the sound-absorbing plate 6, and the filter 52.

[0028] like Figure 3 and Figure 4 As shown, a limiting plate 113 is installed on the cover 11. The silencing plate 6 and the second filter screen 112 are slidably connected to the cover 11. The silencing plate 6 and the second filter screen 112 are in contact with the limiting plate 113. The limiting plate 113 is in contact with the cover 11 via bolt 114. The limiting plate 113 restricts the sliding of the silencing plate 6 and the second filter screen 112, preventing them from detaching from the cover 11. The bolt 114 is used to fix the limiting plate 113 and the cover 11.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0030] Although this document uses a variety of terms, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.
