Description

Technical Field

[0001] The utility model relates to the technical field of earthquake-resistant buffering, and specifically to an earthquake-resistant bracket for fan equipment. Background Art

[0002] In industrial production and urban construction, fan equipment is widely used in ventilation, cooling, dust removal and other aspects. However, due to vibrations such as earthquakes caused by natural disasters or other factors, fan equipment may be affected or even damaged during operation, which poses a severe challenge to the safety and stability of the equipment. In order to meet this challenge, scientists and engineers have begun to pay attention to and study seismic brackets for fan equipment, which can provide effective seismic protection in earthquakes or other vibration conditions, ensuring the normal operation and safety of fan equipment. The design of seismic brackets for fan equipment needs to consider not only the structure and materials of the bracket itself, but also the connection and interaction between the bracket and the foundation and the fan equipment.

[0003] After searching, the Chinese patent publication number CN217842135U discloses "a seismic bracket for hoisting a wind turbine with stable installation, belonging to the technical field of wind turbine equipment, comprising an upper bracket and a lower bracket, two fixing grooves are arranged at the bottom of the lower bracket, and a wind turbine is fixedly connected to the top of the lower bracket, a buffer mechanism, the buffer mechanism comprises four suspension rods, the four suspension rods are movably embedded between the outer surfaces of one side of the upper bracket and the lower bracket, and the four suspension rods are divided into two groups, and a mounting mechanism is arranged on the suspension rod, and the upper bracket and the lower bracket are arranged on the suspension rod in the buffer mechanism, which can firmly clamp the wind turbine fixed above the lower bracket, thereby improving the hoisting stability of the wind turbine, and the buffering performance of the buffer mechanism is further improved by cooperating with the positioning plate and the buffer assembly at the bottom of the suspension rod, so that the seismic resistance of the lower bracket is further improved to avoid damage to the wind turbine, and the installation mechanism is convenient for hoisting the wind turbine between the upper bracket and the lower bracket, thereby improving the installation convenience of the bracket".

[0004] In actual use, the above patent connects the connecting part and the guide column through a spring, and the spring has an inherent vibration frequency. When the earthquake or other external vibration frequency approaches or exceeds the inherent frequency of the spring, the shock absorption effect will be weakened or even fail, and the wind turbine equipment cannot be effectively protected. In addition, the bearing capacity of the spring is limited. When encountering a large earthquake or vibration shock, the spring may not be able to withstand the weight and inertia of the wind turbine equipment, causing the bracket to fail or be damaged. Utility Model Content

[0005] The utility model provides a seismic-resistant bracket for a fan device, which solves the problem that the fan device may not be effectively protected by only using springs for connecting parts and guide columns.

[0006] The technical solution of the utility model is as follows: A seismic support for fan equipment comprises a base plate, the outer side of the top end of the base plate is fixedly connected with a left and right opposite protective plate, the middle side of the top end of the base plate is fixedly connected with a left and right opposite protective frame, the top end of the protective frame is fixedly connected with a uniformly distributed buffer plate, the top end of the buffer plate is fixedly connected with a mounting plate, the middle side of the top end of the protective frame is fixedly connected with a uniformly distributed first damping cylinder, the inner side of the first damping cylinder is slidably connected with a piston rod, the top end of the piston rod is fixedly connected with a connecting column, the outer side of the bottom end of the connecting column is fixedly connected with a first spring, the outer side of the base plate is fixedly connected with a uniformly distributed mounting frame, the outer side of the bottom end of the mounting frame is rotatably connected with a first fixing frame, the outer side of the first fixing frame is rotatably connected with a left and right opposite transmission rod, the inner side of the bottom end of the transmission rod is rotatably connected with a second fixing frame, the outer side of the middle end of the outer transmission rod is rotatably connected with a front-to-back opposite second damping cylinder, the inner side of the second damping cylinder is slidably connected with a second piston, the top end of the second piston is fixedly connected with a fixing rod, and the outer side of the top end of the second damping cylinder is fixedly connected with a second spring.

[0007] Preferably, the mounting plate is fixedly connected to the connecting column, and the mounting plate is slidably connected to the protective plate.

[0008] Preferably, the bottom end of the first spring is fixedly connected to the outer bottom end of the first damping cylinder.

[0009] Preferably, the outer bottom end of the fixing rod is fixedly connected to the top end of the second spring, and the top end of the fixing rod is rotatably connected to the middle end of the inner transmission rod.

[0010] Preferably, the top end of the fixing rod is rotatably connected to the upper end of the inner transmission rod.

[0011] Preferably, the bottom end of the second fixing frame is rotatably connected to left and right supporting feet that are opposite to each other.

[0012] Preferably, a fan is fixedly connected to the top of the mounting plate.

[0013] The working principle and beneficial effects of the utility model are as follows: when an earthquake or vibration occurs, the impact force generated by the vibration is first transmitted to the bottom plate through the supporting feet by using the second fixing frame, the transmission rod, the first fixing frame and the mounting frame, and then transmitted to the protective frame through the bottom plate, and then transmitted to the buffer plate and the first damping cylinder through the protective frame at the same time, and then part of the impact force is converted into heat and dissipated through the deformation of the buffer plate itself, and then part of the impact force is converted into friction force through the friction between the first damping cylinder and the first spring, and the larger friction between the first damping cylinder and the first spring is converted into heat and dissipated, and at the same time, the impact force is also converted to a certain extent through the deformation of the first spring itself, through the above structure The vertical impact force generated by the vibration is absorbed and transformed, and the horizontal impact force is absorbed and transformed through the greater friction between the second damping cylinder and the second piston and the deformation of the second spring, so that the impact force generated by the vibration is damped. The fan may be subjected to impact forces from different directions during an earthquake or other external vibrations. Simultaneous lateral and horizontal shock absorption can protect the equipment in all directions and ensure that it can withstand impacts in all directions. At the same time, the fan may generate various vibrations during operation. Simultaneous lateral and horizontal shock absorption can more comprehensively control the vibration of the equipment, ensure that it maintains stable operation during vibration, and reduce the impact on the surrounding environment and structure.
