Description

Technical Field

[0001] The present invention relates to the technical field of fans, and in particular to a fan. Background Art

[0002] The magnetic levitation fan adopts high-speed permanent magnet motor, active magnetic levitation bearing, direct-connected high-speed three-dimensional flow impeller and other technologies. Compared with traditional fans, it has the advantages of high efficiency, low maintenance cost, long life, etc., and has obvious energy-saving and consumption-reducing effects. It can be widely used in sewage treatment, petrochemical, cement building materials and other industries. At that time, during the operation of the fan, the vibration generated by the operation of the equipment has a great impact on the stability of the fan. The traditional shock absorption method adopts the reinforcement treatment of the fan base. This method has certain disadvantages. After long-term use, vibration conduction will cause mechanical fatigue at the reinforcement, and there is a risk of loosening. Another method is to use shock-absorbing materials for shock absorption treatment, but in the application process of shock-absorbing materials, the material loss is large after long-term use, and the shock absorption effect cannot be effectively guaranteed for a long time. Therefore, a fan is needed. Summary of the invention

[0003] In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide a fan for solving the problem of improving the vibration reduction effect of the fan during use in the prior art.

[0004] In order to achieve the above-mentioned purpose and other related purposes, the present invention provides the following technical solutions:

[0005] A fan comprises a chassis, a fan body arranged in the chassis, a base detachably assembled in the chassis and used to carry the fan body, and a shock absorbing assembly for carrying the fan body is arranged between the bottom of the fan body and the base;

[0006] The shock absorbing assembly includes two groups of relatively arranged upper disc-shaped shock absorbing pads and lower disc-shaped shock absorbing pads, and a shock absorbing base arranged at the bottom of the two groups of relatively arranged upper disc-shaped shock absorbing pads and lower disc-shaped shock absorbing pads for supporting the two groups of relatively arranged upper disc-shaped shock absorbing pads and lower disc-shaped shock absorbing pads, the opening ends of the upper disc-shaped shock absorbing pads and the lower disc-shaped shock absorbing pads are arranged opposite to each other, two groups of fixing ears are symmetrically arranged on both sides of the upper and lower disc-shaped shock absorbing pads of the shock absorbing base, positioning holes are arranged on the two groups of fixing ears, and shock absorbing mounting holes are opened at the center positions of the two groups of relatively arranged upper disc-shaped shock absorbing pads and lower disc-shaped shock absorbing pads.

[0007] To implement the above technical solution, by setting a shock-absorbing assembly to cooperate with the base that supports the fan body, the influence of the vibration generated during the operation of the fan on the installation stability of the fan can be reduced.

The upper disc-shaped shock-absorbing pad and the lower disc-shaped shock-absorbing pad that cooperate in the shape of an hourglass can improve the uniformity of force, thereby ensuring the stability of the upper disc-shaped shock-absorbing pad and the lower disc-shaped shock-absorbing pad in supporting the fan body, and two groups of fixing ears are symmetrically arranged on both sides of the lower disc-shaped shock-absorbing pad, which can ensure the convenience of installation of the shock-absorbing base while avoiding the influence of the fixing ears on the supporting stability of the shock-absorbing base.

[0008] In one embodiment of the present invention, a support plate is provided between the bottom of the lower disc-shaped shock-absorbing pad and the shock-absorbing base, the open end of the support plate is arranged toward the shock-absorbing base, and the maximum radial dimension of the support plate is arranged to be the same as the maximum radial dimension of the upper disc-shaped shock-absorbing pad.

[0009] To implement the above technical solution, by setting up a support plate, the force of the lower disc-shaped shock-absorbing pad can be more evenly dispersed to the shock-absorbing base, thereby ensuring the support stability of the shock-absorbing base. The maximum radial dimension of the support plate is set to be the same as the maximum radial dimension of the upper disc-shaped shock-absorbing pad, which can better ensure the uniformity of force dispersion after the support plate is compressed, thereby ensuring the support stability of the support plate.

[0010] In one embodiment of the present invention, the upper disc-shaped shock-absorbing pad, the lower disc-shaped shock-absorbing pad and the supporting plate are all made of rubber.

[0013] To implement the above technical solution, the bottom of the upper disc-shaped shock-absorbing pad is wrapped around the top of the lower disc-shaped shock-absorbing pad, which can better and evenly transmit the pressure on the upper disc-shaped shock-absorbing pad to the lower disc-shaped shock-absorbing pad, thereby improving the use stability of the upper disc-shaped shock-absorbing pad and the lower disc-shaped shock-absorbing pad.

[0015] To implement the above technical solution, in order to reduce the weight of the equipment, the base is configured as a U-shaped base with a hollow interior. In order to ensure the supporting stability of the base while reducing the weight, a hollow shock-absorbing cabin in the hollow space at the bottom of the upper end surface of the base is utilized to ensure the supporting stability of the base while reducing the damage to the base caused by vibration.

[0016] In one embodiment of the present invention, a mounting plate extending toward both ends along a horizontal direction is provided at the bottom end of the base connected to the chassis, and a U-shaped mounting through groove is provided on the mounting plate.

[0017] To implement the above technical solution, the arrangement of the mounting plate can facilitate the connection and cooperation between the base and the chassis, and the arrangement of the U-shaped mounting groove is to facilitate fixing the base into the chassis.

[0018] In one embodiment of the present invention, four groups of the shock absorbing components are provided between the bottom of the fan body and the base.

[0019] The implementation of the above technical solution can better ensure the stability of the fan body during operation, and can also more evenly disperse the vibration force generated by the fan body during operation, thereby improving the operating stability of the equipment.

[0029] See also Figures 1 to 5 The present invention provides a fan, comprising a chassis 1, a fan body 2 arranged in the chassis 1, a base 3 detachably assembled in the chassis 1 and used for carrying the fan body 2, a shock-absorbing component for carrying the fan body 2 is provided between the bottom of the fan body 2 and the base 3, the shock-absorbing component comprises two groups of upper disc-shaped shock-absorbing pads 4 and lower disc-shaped shock-absorbing pads 5 arranged opposite to each other, and a shock-absorbing base 6 arranged at the bottom of the two groups of disc-shaped shock-absorbing pads for supporting the two groups of disc-shaped shock-absorbing pads, the opening ends of the upper disc-shaped shock-absorbing pad 4 and the lower disc-shaped shock-absorbing pad 5 are arranged opposite to each other, two groups of fixing ears 7 are symmetrically provided on the shock-absorbing base 6 and on both sides of the lower disc-shaped shock-absorbing pad 5, positioning holes are provided on the two groups of fixing ears 7, and shock-absorbing mounting holes 8 are opened at the center positions of the two groups of disc-shaped shock-absorbing pads.

[0030] To implement the above technical solution, by setting a shock-absorbing assembly to cooperate with the base 3 supporting the fan body 2, the influence of the vibration generated during the operation of the fan on the installation stability of the fan can be reduced. Through two groups of relatively arranged upper disc-shaped shock-absorbing pads 4 and lower disc-shaped shock-absorbing pads 5, the upper disc-shaped shock-absorbing pad 4 is connected to the bottom of the fan, and the pressure applied by the fan is evenly dispersed circumferentially, thereby ensuring the force uniformity of the upper disc-shaped shock-absorbing pad 4, and after the lower disc-shaped shock-absorbing pad 5 receives the pressure transmitted from the upper disc-shaped shock-absorbing pad 4, the force is evenly dispersed to the shock-absorbing base 6 again. The upper disc-shaped shock-absorbing pad 4 and the lower disc-shaped shock-absorbing pad 5 that cooperate in the shape of an hourglass can improve the force uniformity, thereby ensuring the stability of the upper disc-shaped shock-absorbing pad 4 and the lower disc-shaped shock-absorbing pad 5 on the fan body 2, and two groups of fixing ears 7 are symmetrically arranged on both sides of the lower disc-shaped shock-absorbing pad 5, which can ensure the convenience of installation of the shock-absorbing base 6 while avoiding the fixing ears 7 from affecting the supporting stability of the shock-absorbing base 6.

[0031] A support plate 9 is provided between the bottom of the lower disc-shaped shock-absorbing pad 5 and the shock-absorbing base 6. The open end of the support plate 9 is arranged toward the shock-absorbing base 6, and the maximum radial dimension of the support plate 9 is set to be the same as the maximum radial dimension of the upper disc-shaped shock-absorbing pad 4. By setting the support plate 9, the force of the lower disc-shaped shock-absorbing pad 5 can be more evenly dispersed to the shock-absorbing base 6, thereby ensuring the support stability of the shock-absorbing base 6. Setting the maximum radial dimension of the support plate 9 to be the same as the maximum radial dimension of the upper disc-shaped shock-absorbing pad 4 can better ensure the uniformity of force dispersion after the support plate 9 is compressed, thereby ensuring the support stability of the support plate 9.

[0032] The upper disc-shaped shock-absorbing pad 4, the lower disc-shaped shock-absorbing pad 5 and the support plate 9 are all made of rubber material. On the one hand, the elastic properties of the rubber material itself can be used to reduce the impact of vibration on the surrounding working surface during the operation of the fan body 2. On the other hand, the rubber material itself has certain elastic properties, thereby reducing the damage caused by vibration to the upper disc-shaped shock-absorbing pad 4, the lower disc-shaped shock-absorbing pad 5 and the support plate 9.

[0033] The maximum radial dimension of the lower disc-shaped shock-absorbing pad 5 is smaller than the maximum radial dimension of the upper disc-shaped shock-absorbing pad 4, and the bottom of the upper disc-shaped shock-absorbing pad 4 wraps the top of the lower disc-shaped shock-absorbing pad 5. The bottom of the upper disc-shaped shock-absorbing pad 4 wraps the top of the lower disc-shaped shock-absorbing pad 5, which can better and evenly transmit the pressure exerted on the upper disc-shaped shock-absorbing pad 4 to the lower disc-shaped shock-absorbing pad 5, thereby improving the use stability of the upper disc-shaped shock-absorbing pad 4 and the lower disc-shaped shock-absorbing pad 5.

In order to reduce the weight of the equipment, the base 3 is arranged as a hollow U-shaped base 3. In order to ensure the supporting stability of the base 3 while reducing the weight, the hollow shock-absorbing cabin 10 in the hollow space at the bottom of the upper end surface of the base 3 is used to ensure the supporting stability of the base 3 and reduce the damage to the base 3 caused by vibration.

[0035] The bottom end of the base 3 connected to the chassis 1 is provided with a mounting plate 11 extending horizontally to both ends, and a U-shaped mounting groove 12 is provided on the mounting plate 11. The setting of the mounting plate 11 can facilitate the connection and cooperation between the base 3 and the chassis 1. The setting of the U-shaped mounting groove 12 is to facilitate the fixing of the base 3 to the chassis 1. Four groups of shock-absorbing components are provided between the bottom of the fan body 2 and the base 3, which can better ensure the stability of the fan body 2 during operation, and at the same time can more evenly disperse the vibration force generated by the fan body 2 during operation, thereby improving the operation stability of the equipment.

[0036] The present invention can reduce the influence of vibration generated during the operation of the fan on the installation stability of the fan by arranging a shock-absorbing assembly to cooperate with the base that supports the fan body. Through two groups of relatively arranged upper disc-shaped shock-absorbing pads and lower disc-shaped shock-absorbing pads, the upper disc-shaped shock-absorbing pad is connected to the bottom of the fan to evenly disperse the pressure applied by the fan in the circumferential direction, thereby ensuring the force uniformity of the upper disc-shaped shock-absorbing pad. After the lower disc-shaped shock-absorbing pad receives the pressure transmitted from the upper disc-shaped shock-absorbing pad, it disperses the force evenly to the shock-absorbing base again. The upper disc-shaped shock-absorbing pad and the lower disc-shaped shock-absorbing pad that cooperate in the shape of an hourglass can improve the force uniformity, thereby ensuring the stability of the upper disc-shaped shock-absorbing pad and the lower disc-shaped shock-absorbing pad in supporting the fan body. Two groups of fixing ears are symmetrically arranged on both sides of the lower disc-shaped shock-absorbing pad, which can ensure the convenience of installation of the shock-absorbing base while avoiding the influence of the fixing ears on the supporting stability of the shock-absorbing base.
