Description

Technical Field

[0001] The utility model belongs to the technical field of refrigeration fan equipment, and particularly relates to a refrigeration fan base with a damping and shock-absorbing structure. Background Art

[0002] When designing many refrigeration fan bases, the characteristics of vibration transmission are not fully considered, and often a single material or structure is used, resulting in insufficient seismic performance. During the operation of the equipment, the vibration generated by the rotation of the fan impeller is directly transmitted to the ground through the base. This not only causes a large amount of noise during the operation of the equipment, but also may lead to fatigue damage of the surrounding structures and shorten the service life. In addition, the contact area and contact method between the base and the ground are not reasonably designed, which will also cause insufficient effective absorption of vibration energy, further reducing the shock-absorbing effect.

[0003] The conventional countermeasures are to buffer the vibration by adding shock pads or using elastic materials. However, although these methods improve the shock-absorbing effect to a certain extent, they have some drawbacks. For example, the shock pads are prone to aging and losing elasticity during long-term use, thereby reducing their shock-absorbing performance and even affecting the stability of the fan. Therefore, we hope to design a refrigeration fan base with a new structure to solve this problem. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a refrigeration fan base with a damping and shock-absorbing structure to solve the problems raised in the above background art.

[0005] The utility model is realized through the following technical solutions: a refrigeration fan base with a damping and shock-absorbing structure, including: a bottom plate, a shock-absorbing component, and a refrigeration fan body. A plurality of shock-absorbing components are fixed on the upper side of the bottom plate, and the refrigeration fan body is fixed on the upper side of the bottom plate through a plurality of shock-absorbing components;

[0006] An installation foot is welded on the left, middle, and right sides of the lower end of the refrigeration fan body respectively;

[0007] The shock-absorbing component includes a cylinder body, a telescopic rod, a movable plate one, a movable plate two, and a magnetic ring two. The lower end of the telescopic rod is slidably installed inside the cylinder body;

[0008] The lower end of the telescopic rod is fixed with a movable plate two, the upper side of the telescopic rod is fixed with a movable plate one, a magnetic ring two is fixed in the middle of the cylinder body, and the lower side of the telescopic rod is slidably connected with the middle of the magnetic ring two.

[0009] As a preferred embodiment, the shock-absorbing assembly further includes a supporting plate, a screw rod, and a spring. The bottom of the telescopic rod is fixedly connected to the upper end of the spring through a first movable plate. A supporting plate is provided at the upper end of the telescopic rod. In actual use, the spring is in a compressed state initially and can provide sufficient supporting force for the telescopic rod.

[0010] As a preferred embodiment, a rubber layer is provided on the top of the supporting plate. A screw rod is provided in the middle of the bottom of the supporting plate. The screw rod is fixedly connected to the mounting foot through a nut and a mounting hole reserved on the mounting foot.

[0011] As a preferred embodiment, the first movable plate includes a first circular plate and a first magnetic ring. The first magnetic ring is fixedly provided on the upper side of the first circular plate. The lower end of the telescopic rod penetrates through the middle of the first magnetic ring and is fixedly connected to the middle of the top surface of the first circular plate. A plurality of through holes are formed by penetrating downward from the edge of the upper surface of the first circular plate.

[0012] As a preferred embodiment, a plurality of first communication holes are formed by penetrating downward from the edge of the upper surface of the first magnetic ring. The number and distribution positions of the first communication holes are both matched with the number and distribution positions of the through holes. The side of the first magnetic ring is slidably connected to the inner wall of the cylinder. In actual use, oil is injected into the bottom of the cylinder, and the height of the oil should be such that it covers the upper side of the first magnetic ring and is lower than the lower side of the second magnetic ring.

[0013] As a preferred embodiment, a plurality of second communication holes are formed by penetrating downward from the upper surface of the second magnetic ring. The diameter of the first magnetic ring is the same as the diameter of the second magnetic ring. The magnetic pole on the upper side of the first magnetic ring is the same as the magnetic pole on the lower side of the second magnetic ring.

[0014] As a preferred embodiment, the second movable plate includes a third magnetic ring and a second circular plate. The lower side of the second circular plate is fixedly connected to the upper surface of the third magnetic ring. The side of the third magnetic ring is slidably connected to the inner wall of the cylinder. The magnetic pole on the lower side of the third magnetic ring is the same as the magnetic pole on the upper side of the second magnetic ring.

[0015] After adopting the above technical solution, the beneficial effects of the present utility model are as follows: With the setting of the shock-absorbing component, in actual use, the lower end of the refrigeration fan body is installed through the mounting feet and multiple shock-absorbing components, and is connected to the bottom plate through the shock-absorbing components. When the refrigeration fan body operates, the vibration generated by it will be transmitted to the telescopic rod through the mounting feet and the screw rod. Under the action of the vibration energy, the telescopic rod generates a downward movement, and drives the movable plate one and the movable plate two to move downward synchronously inside the cylinder body. The magnetic pole on the lower side of the magnetic ring three is the same as the magnetic pole on the upper side of the magnetic ring two, and the lower end of the telescopic rod is fixedly connected to the upper end of the spring through the movable plate one. When the telescopic rod moves downward, the repulsive force, frictional force between the magnetic ring two and the magnetic ring three, and the spring restoring potential energy cooperate with each other, and have a large damping to prevent the telescopic rod from moving downward. When the downward impact force of the telescopic rod is less than the repulsive force, frictional force between the magnetic ring two and the magnetic ring three, and the spring restoring potential energy, at this time, the downward movement action of the telescopic rod is completed. Subsequently, the telescopic rod is reset under the action of the repulsive force, frictional force between the magnetic ring two and the magnetic ring three, and the spring restoring potential energy. Moreover, since the magnetic pole on the upper side of the magnetic ring one is the same as the magnetic pole on the lower side of the magnetic ring two, the repulsive force between the magnetic ring one and the magnetic ring two, in cooperation with the weight of the refrigeration fan body shared by the telescopic rod, the movable plate one, the movable plate two, and their respective shock-absorbing components, jointly generates a damping to resist the reset of the telescopic rod, and thus can effectively damp the vibration generated by the refrigeration fan body.

[0016] With the setting of the magnetic ring one and the magnetic ring two, since the oil liquid is injected into the bottom of the cylinder body, and a plurality of communication holes one are formed by the downward penetration of the edge of the upper surface of the magnetic ring one, the number and distribution positions of the communication holes one are matched with the number and distribution positions of the through holes, and a plurality of communication holes two are formed by the downward penetration of the upper surface of the magnetic ring two. This enables the telescopic rod to be subject to the damping effect of the oil liquid whether it impacts and moves downward or resets and moves upward, which can greatly increase the resistance received by the telescopic rod when it impacts and moves downward and resets and moves upward, and thus can effectively cancel and damp the vibration.

[0025] Please refer to Figures 1 to 3 , the present utility model provides a technical solution: a base of a refrigeration fan with a damping shock-absorbing structure, including: a bottom plate 100, a shock-absorbing assembly 200, and a refrigeration fan body 300.

[0027] The shock-absorbing assembly 200 includes a cylinder body 210, a telescopic rod 250, a movable plate 1 220, a movable plate 2 240, and a magnetic ring 2 230. The lower end of the telescopic rod 250 is slidably installed inside the cylinder body 210;

[0029] Please refer to Figures 2 to 3, the shock absorption assembly 200 further includes a supporting plate 260, a screw 270, and a spring 280. The bottom of the telescopic rod 250 is fixedly connected to the upper end of the spring 280 through the movable plate one 220. A supporting plate 260 is provided at the upper end of the telescopic rod 250. In actual use, the spring 280 is in a compressed state initially and can provide sufficient supporting force for the telescopic rod 250.

[0030] A rubber layer is provided on the top of the supporting plate 260. A screw 270 is provided in the middle of the bottom of the supporting plate 260. The screw 270 is fixedly connected to the mounting foot 310 through a nut and a mounting hole reserved on the mounting foot 310.

[0031] The movable plate one 220 includes a circular plate one 221 and a magnetic ring one 224. The magnetic ring one 224 is fixedly provided on the upper side of the circular plate one 221. The lower end of the telescopic rod 250 passes through the middle of the magnetic ring one 224 and is fixedly connected to the middle of the top of the circular plate one 221. A plurality of through holes 222 are formed by penetrating downward from the edge of the upper surface of the circular plate one 221.

[0032] A plurality of communication holes one 223 are formed by penetrating downward from the edge of the upper surface of the magnetic ring one 224. The number and distribution positions of the communication holes one 223 are both matched with the number and distribution positions of the through holes 222. The side of the magnetic ring one 224 is slidably connected to the inner wall of the cylinder 210. In actual use, oil is injected into the bottom of the cylinder 210, and the height of the oil is preferably such that it covers the upper side of the magnetic ring one 224 and is lower than the lower side of the magnetic ring two 230.

[0033] As the first embodiment of the present invention, due to the oil being injected into the bottom of the cylinder 210, and a plurality of communication holes one 223 being formed by penetrating downward from the edge of the upper surface of the magnetic ring one 224, with the number and distribution positions of the communication holes one 223 being both matched with the number and distribution positions of the through holes 222, and a plurality of communication holes two 231 being formed by penetrating downward from the upper surface of the magnetic ring two 230, the telescopic rod 250 is subject to the damping effect of the oil whether it moves downward due to impact or moves upward during reset, which can greatly increase the resistance received by the telescopic rod 250 when moving downward due to impact and moving upward during reset, and thus can effectively cancel and absorb the vibration.

[0034] Please refer to Figures 1 to 3 , a plurality of communication holes two 231 are formed by penetrating downward from the upper surface of the magnetic ring two 230. The diameter of the magnetic ring one 224 is the same as the diameter of the magnetic ring two 230, and the magnetic pole on the upper side of the magnetic ring one 224 is the same as the magnetic pole on the lower side of the magnetic ring two 230.

[0035] The movable plate two 240 includes a magnetic ring three 241 and a circular plate two 242. The lower side of the circular plate two 242 is fixedly connected to the upper surface of the magnetic ring three 241.

[0036] As the second embodiment of the present utility model, based on the above-mentioned first embodiment, in actual use, the lower end of the refrigeration fan body 300 is installed through the mounting feet 310 and a plurality of shock absorption components 200, and is connected to the bottom plate 100 through the shock absorption components 200. When the refrigeration fan body 300 operates, the vibration generated by it will be transmitted to the telescopic rod 250 through the mounting feet 310 and the screw rod 270. The telescopic rod 250 generates a downward movement under the action of the vibration energy, and drives the movable plate one 220 and the movable plate two 240 to synchronously move downward inside the cylinder body 210. The magnetic pole on the lower side of the magnetic ring three 241 is the same as the magnetic pole on the upper side of the magnetic ring two 230, and the lower end of the telescopic rod 250 is fixedly connected to the upper end of the spring 280 through the movable plate one 220;

[0037] When the telescopic rod 250 moves downward, the repulsive force, frictional force between the magnetic ring two 230 and the magnetic ring three 241, and the restoring potential energy of the spring 280 cooperate with each other, and have a large damping to prevent the telescopic rod 250 from moving downward. When the downward impact force of the telescopic rod 250 is less than the repulsive force, frictional force between the magnetic ring two 230 and the magnetic ring three 241, and the restoring potential of the spring 280, at this time, the downward movement action of the telescopic rod 250 is completed. Subsequently, the telescopic rod 250 resets under the action of the repulsive force, frictional force between the magnetic ring two 230 and the magnetic ring three 241, and the restoring potential of the spring 280. Again, because the magnetic pole on the upper side of the magnetic ring one 224 is the same as the magnetic pole on the lower side of the magnetic ring two 230, the repulsive force between the magnetic ring one 224 and the magnetic ring two 230, in cooperation with the weight of the refrigeration fan body 300 shared by the telescopic rod 250, the movable plate one 220, the movable plate two 240, and their respective shock absorption components 200, jointly cooperate to generate a damping to resist the reset of the telescopic rod 250, and thus can effectively damp the vibration generated by the refrigeration fan body 300.

[0038] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
