[0030] Such as figure 1 As shown, the centrifugal universal fan shock absorber includes a first mounting plate 100, a second mounting plate 200, a shock absorbing mechanism 300 and a shock absorbing mechanism 400, the fan is installed on the top of the first mounting plate 100, and the first mounting plate 100 By installing at least two shock absorbing mechanisms 300 on the upper part of the second installation board 200 , the second installation board 200 can be fixed on the ground or a workbench, that is, the position of the second installation board 200 is fixed. The shock absorbing mechanism 300 is an elastically deformable structure, and is hollow in the axial direction of the shock absorbing mechanism 300 . Both ends of the shock absorbing mechanism 300 in the axial direction are in contact with the first mounting plate 100 and the second mounting plate 200 respectively. A shock-absorbing mechanism 400 is connected between two adjacent shock-absorbing mechanisms 300, and...

[0036] Such as figure 2 As shown, the difference from the first embodiment is that the shock absorber mechanism 400 also includes two first movable plugs 410, and the two first movable plugs 410 can be respectively inside the shock absorber mechanism 400 and along the shock absorber mechanism 400. Axial direction movement, wherein, each first movable plug 410 corresponds to one shock absorbing mechanism 300, in addition, located inside the shock absorbing mechanism 400, and an oil chamber 402 is formed between the two first movable plugs 410, the oil chamber The inside of 402 is provided with hydraulic oil, and the oil cavity 402 can be in the shape of an I. In this way, the high-pressure gas formed in the shock absorbing mechanism 300 pushes the first movable plug 410 to move, so that the two first movable plugs 410 in the same shock absorbing mechanism 400 move relatively to squeeze the hydraulic oil, thereby eliminating the vibration force.

[0042] Such as image 3 As shown, the difference from the first embodiment is that the shock absorbing mechanism 400 also includes a first movable plug 410 and a second movable plug 420, and the first movable plug 410 and the second movable plug 420 can move in the shock absorbing mechanism 400 inside, and move along the axial direction of the shock absorbing mechanism 400 , wherein the first movable piston 410 corresponds to the adjacent shock absorbing mechanism 300 , and the second movable piston 420 corresponds to the adjacent shock absorbing mechanism 300 . The oil cavity 402 located inside the shock absorbing mechanism 400 and formed between the first movable piston 410 and the second movable piston 420 is provided with hydraulic oil inside the oil cavity 402 . In addition, the axial direction of the second movable plug 420 is a hollow structure, and an elastic film 421 is provided at the opposite end of the second movable plug 420 and the first movable plug 410.

Abstract

The invention discloses a centrifugal universal fan shock absorber which comprises a first mounting plate, a second mounting plate, damping mechanisms and a suspension mechanism. The first mounting plate is used for allowing a fan to be mounted. The second mounting plate is located on the lower portion of the first mounting plate. The damping mechanisms are elastically deforming hollow structures,and the two ends of each damping mechanism are in butt joint with the first mounting plate and the second mounting plate correspondingly. The two ends of the suspension mechanism are connected with the two adjacent damping mechanisms correspondingly. When the first mounting plate vibrates due to work of the fan, the damping mechanisms are extruded, so that air pressure in the damping mechanisms is increased, and high-pressure air is formed. The high-pressure air can flow to the adjacent damping mechanisms along with the suspension mechanism, then a high-pressure air hedging phenomenon is achieved, and a suspension effect is achieved.

Description

technical field [0001] The invention belongs to the field of fans, in particular to a centrifugal universal fan shock absorber. Background technique [0002] Centrifugal general fan (hereinafter referred to as fan) is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is widely used in ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings. But at the same time, the fan will generate noise during operation, which not only interferes with people's normal rest, endangers the physical and mental health of producers, but also damages buildings and equipment. Therefore, as one of the important contents of improving working conditions and protecting the environment, the control of fan noise is particularly urgent. [0003] When the fan is running under certain working conditions, the noise generated can be divided into mechanical noise. Among them, the mechanical noise is cause...
