Description

Technical Field

[0001] The utility model relates to the field of motor noise reduction, in particular to a motor noise reduction cover. Background Art

[0002] A motor is a device that uses electrical energy to rotate. It is mainly used to drive equipment in the industrial field. The motor will generate a lot of noise during operation. In order to reduce the motor noise, a noise reduction cover is usually installed outside the motor to block the transmission of motor noise.

[0003] However, the existing motor noise reduction cover is usually installed by directly placing it or fixing it using a motor mounting platform. It cannot be connected to the motor itself, so that the installation position is greatly restricted. The motor mounting platform has high requirements. The noise reduction cover needs to match the motor mounting platform in model. When the motor is replaced with a different platform for installation, the noise reduction cover cannot be installed, resulting in poor applicability of the noise reduction cover.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A motor noise reduction cover comprises a support, the upper shaft of the support is connected to a shield, and the upper surface of the support is provided with a connecting groove, the top of the shield is fixedly mounted with a magnetic strip, and the center position of one side of the magnetic strip is fixedly mounted with a protrusion, the inner side of which is glued and connected with a first sound insulation cotton, and a protrusion is fixedly mounted on the inner surface of the first sound insulation cotton, a rear baffle is fixedly mounted on the rear of the shield, and the front of the rear baffle is glued and connected with a second sound insulation cotton.

[0007] As a further solution of the utility model, a heat dissipation hole is provided on the rear surface of the rear baffle, a heat dissipation mesh hole is provided on the front surface of the second sound insulation cotton, and the heat dissipation mesh hole is connected to the heat dissipation hole.

[0008] As a further solution of the utility model, the support and the shield are provided in two groups, and the magnetic strips of the two groups of shields are magnetically connected.

[0009] As a further solution of the utility model, the support is arranged in an "L" shape, and the shield is connected to the top of the vertical section of the support.

[0010] As a further solution of the utility model, the shield is arranged in an arc shape.

[0011] The beneficial effects of the utility model are as follows:

[0012] By setting the support to match the connecting groove, the entire noise reduction cover can be conveniently set on the upper part of the motor base. It is fixed as the motor is installed, and the installation is convenient and fast. Moreover, the installation position can be changed as the motor is installed, and there is no restriction on the motor installation platform, which has high applicability.

[0013] By setting a protective cover to cooperate with the first sound insulation cotton and the support, the support and the protective cover are connected in a rotating manner, and the two protective covers are connected by magnetic attraction. During operation, when the motor generates high heat, the protective cover can be opened in time to dissipate heat for the motor, which is more convenient when dealing with high heat, maintenance, and inspection of the motor.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-Figure 5 As shown, a motor noise reduction cover includes a support 2, a protective cover 4 is axially connected to the upper part of the support 2, and a connecting groove 3 is opened on the upper surface of the support 2, a magnetic strip 5 is fixedly installed on the top of the protective cover 4, and a first sound insulation cotton 7 is glued and connected to the inner side of a protrusion 6 fixedly installed at the center position of one side of the magnetic strip 5, and a protrusion 8 is fixedly installed on the inner surface of the first sound insulation cotton 7, a rear baffle 9 is fixedly installed on the rear of the protective cover 4, and a second sound insulation cotton 10 is glued and connected to the front of the rear baffle 9.

[0022] In this embodiment, a heat dissipation hole is opened on the rear surface of the rear baffle 9, and a heat dissipation mesh hole 11 is opened on the front surface of the second sound insulation cotton 10, and the heat dissipation mesh hole 11 is connected to the heat dissipation hole;

[0023] The heat dissipation holes cooperate with the heat dissipation mesh 11 to dissipate heat for the motor 1 , thereby ensuring good heat dissipation of the motor 1 .

[0024] In this embodiment, the support 2 and the shield 4 are provided in two groups, and the magnetic strips 5 of the two groups of shields 4 are magnetically connected;

[0025] The two magnetic strips 5 can magnetically connect the two shields 4 together, and the magnetic attraction method makes the fixation of the two shields 4 more convenient and quick.

[0026] In this embodiment, the support 2 is arranged in an "L" shape, and the shield 4 is connected to the top of the vertical section of the support 2;

[0027] The support 2 cooperates with the connecting groove 3 to be connected to the base of the motor 1 when the motor 1 is installed, so that the noise reduction cover can be replaced with the motor 1 to any installation platform.

[0028] In this embodiment, the shield 4 is arranged in an arc shape;

[0029] The arc-shaped shield 4 can adapt to the cylindrical shape of the motor 1 and has better wrapping performance.

[0030] It should be noted that the utility model is a motor noise reduction cover. When using it, when installing the motor 1, the two supports 2 are placed on the upper part of the base on both sides of the motor 1, so that the connecting groove 3 is aligned with the mounting hole of the base of the motor 1, and then the external bolts are penetrated for installation. After installation, the entire noise reduction cover can be connected to the motor 1;

[0031] When the motor 1 is working, the two shields 4 can be turned over and connected magnetically through the magnetic strip 5, so that the shield 4 can be covered on the outside of the motor 1. The noise generated by the motor 1 can be blocked by the convex head 8, the first sound insulation cotton 7 and the second sound insulation cotton 10, thereby reducing the noise transmission and improving the comfort of the people around.

[0032] When the motor 1 generates high heat, the two magnetic strips 5 can be separated again, and the protective cover 4 can be turned over so as not to block the motor 1, so as to dissipate heat from the motor 1.

[0033] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
