Description

Technical Field

[0001] This utility model relates to the field of air source heat pump fan technology, and in particular to a vibration damping device for air source heat pump fans. Background Technology

[0002] An air source heat pump is an energy-saving device that utilizes higher-grade energy to transfer heat from a lower-grade heat source (air) to a higher-grade heat source. It is a type of heat pump. As the name suggests, a heat pump, like a pump, can convert low-grade heat energy (such as the heat contained in air, soil, and water) that cannot be directly used into usable high-grade heat energy, thereby saving some high-grade energy (such as coal, natural gas, oil, and electricity). Currently, heat pump fans are generally installed directly on the ceiling. During operation, vibration is directly transmitted to the ceiling. When the motor power is high, there will be significant vibration and noise from the unit.

[0003] Publication (Announcement) No.: CN214887969U discloses a vibration damping device for an air source heat pump fan, including a base plate, an anti-slip plate connected to the lower end of the base plate, a second vibration damping device connected to the top of the base plate, first vibration damping devices inserted into both sides of the top of the second vibration damping device, a placement plate connected to the top of the two first vibration damping devices, a sliding groove opened on both sides of the top of the placement plate, two sliders slidably connected in each of the two sliding grooves, and a fixing device connected to the top of the two sliders with corresponding front and rear positions, multiple positioning holes opened at both ends of the placement plate, and a stabilizing hole for use with the positioning holes opened at one end of each of the four sliders, and fastening bolts for use with the positioning holes and stabilizing holes provided at both ends of the placement plate.

[0004] While the above solution can securely fix air source heat pump fans of different sizes, the adjustment process is relatively complicated, and it can only fix air source heat pump fans of the corresponding size. It cannot fix fans of different sizes or irregular shapes, and the applicability of the device is poor. Utility Model Content

[0005] The main purpose of this utility model is to provide a vibration damping device for air source heat pump fans. By setting a fixing mechanism and a limiting mechanism, it solves the problem that it is impossible to fix fans that are outside the standard size or have irregular shapes, and the device has poor applicability.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A vibration damping device for an air source heat pump fan includes a support base, a fixed platform movably disposed on the top of the support base for supporting the air source heat pump fan, and a spring vibration damper fixedly connected to the inner bottom wall of the support base. The top of the spring vibration damper is fixedly connected to the bottom of the fixed platform. The device also includes a fixing mechanism fixedly connected to the top of the fixed platform and a limiting mechanism connected to the fixing mechanism.

[0008] The fixing mechanism includes a column fixedly connected to the top of the fixing platform and a movable plate rotatably connected to the outer surface of the column for supporting the fixing components.

[0009] The limiting mechanism includes a storage groove formed on the outer wall of the column, a positioning spring fixedly connected to the bottom of the storage groove, and a positioning block fixedly connected to the positioning spring for limiting the movable plate.

[0010] Preferably, the fastener includes a threaded rod that passes through and is threadedly connected to the movable plate, a rubber pad that is fixedly connected to the bottom end of the threaded rod, and a rubber pad that is fixedly connected to the top of the fixed platform.

[0011] Preferably, the fixing mechanism further includes a right-angle plate fixedly connected to the outer wall of the fixing platform, a sliding hole opened on the outer wall of the right-angle plate, a connecting spring fixedly connected to the outer wall of the right-angle plate, and an annular magnet fixedly connected to the end face of the connecting spring.

[0012] Preferably, the fixing mechanism further includes a T-shaped column fixedly connected to the inner wall of the annular magnet, wherein the diameter of the column cap of the T-shaped column is greater than the width of the right-angle plate.

[0013] Preferably, the fixing mechanism further includes limiting holes formed on the outer side wall of the movable plate, and the number of limiting holes is several, and they are distributed in a ring at equal intervals.

[0014] Preferably, the limiting mechanism further includes positioning grooves formed on the inner sidewall of the movable plate, the number of positioning grooves being equal to the number of limiting holes, and each positioning groove being located directly above a corresponding limiting hole.

[0015] Preferably, the positioning block includes a cylinder fixedly connected to the end face of the positioning spring, and a hemisphere fixedly connected to the end face of the cylinder, wherein the central axis of the positioning block and the central axis of the positioning groove are located on the same horizontal plane.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] I. In this utility model, the air source heat pump fan is placed on top of the anti-slip mat, and the movable plate is rotated to move the rubber pad above the fan. Then, the movable plate is finely adjusted until an impact sound is heard. At this time, the positioning block is inserted into the positioning groove under the action of the positioning spring, and one of the limiting holes is aligned with the T-shaped column. Then, the T-shaped column is pushed so that the ring magnet is disengaged from the adsorption range of the right-angle plate, and the connecting spring returns to its original state. At this time, the T-shaped column is inserted into the inside of the limiting hole, thereby fixing the movable plate. Then, the threaded rod is rotated to move the rubber pad against the fan, thereby fixing one corner of the fan. Finally, the above operation is repeated to fix all four corners of the fan. Because the rubber pad can move in an arc under the action of the movable plate, its position is variable, and each rubber pad operates independently, so it can be adapted to fans of different sizes and shapes, and the device has strong applicability.

[0018] II. In this utility model, if the positioning groove and the storage groove intersect during the rotation of the movable plate, the positioning block will be completely retracted into the storage groove, and the positioning spring will be in a compressed state. If the positioning groove is aligned with the storage groove, the positioning block will be inserted into the positioning groove under the action of the positioning spring, making a sound, and one of the limiting holes will be aligned with the T-shaped column, thereby quickly achieving the positioning effect.

Detailed Implementation

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] Example 1: As Figure 1-6 As shown, a vibration damping device for an air source heat pump fan includes a support base 1, a fixed platform 2 movably disposed on the top of the support base 1 for supporting the air source heat pump fan, and a spring vibration damper 5 fixedly connected to the inner bottom wall of the support base 1. The top of the spring vibration damper 5 is fixedly connected to the bottom of the fixed platform 2. The device also includes a fixing mechanism fixedly connected to the top of the fixed platform 2, and a limiting mechanism connected to the fixing mechanism. The vibration of the fan during operation is reduced by the spring vibration damper 5.

[0028] The fixing mechanism includes a column 301 fixedly connected to the top of the fixing platform 2 and a movable plate 302 rotatably connected to the outer surface of the column 301 for supporting the fixing components.

[0029] The limiting mechanism includes a storage groove formed on the outer wall of the column 301, a positioning spring 401 fixedly connected to the bottom of the storage groove, and a positioning block 402 fixedly connected to the positioning spring 401 for limiting the movable plate 302.

[0030] The fixing component includes a threaded rod 303 that passes through and is threadedly connected to the movable plate 302, a rubber pad 304 fixedly connected to the bottom end of the threaded rod 303, and a rubber pad 305 fixedly connected to the top of the fixing platform 2. By placing the air source heat pump fan on top of the anti-slip pad 305 and rotating the movable plate 302, the rubber pad 304 is positioned above the fan. Then, the threaded rod 303 is rotated so that the rubber pad 304 supports the fan, thereby fixing the fan. The rubber pad 304 and the anti-slip pad 304 prevent damage to the fan when fixing it.

[0031] The fixing mechanism also includes a right-angle plate 306 fixedly connected to the outer wall of the fixing platform 2, a sliding hole opened on the outer wall of the right-angle plate 306, a connecting spring 307 fixedly connected to the outer wall of the right-angle plate 306, and an annular magnet 308 fixedly connected to the end face of the connecting spring 307. The right-angle plate 306 is made of ferromagnetic material. When the annular magnet 308 is attracted to the right-angle plate 306, the connecting spring 307 is in a compressed state.

[0032] The fixing mechanism also includes a T-shaped post 309 fixedly connected to the inner wall of the annular magnet 308. The diameter of the post cap of the T-shaped post 309 is greater than the width of the right angle plate 306. The outer diameter of the T-shaped post 309 is equal to the inner diameter of the sliding hole, and the T-shaped post 309 slides inside the sliding hole.

[0033] The fixing mechanism also includes a limiting hole 3010 opened on the outer wall of the movable plate 302. There are several limiting holes 3010, which are distributed in a ring at equal intervals. The inner diameter of the limiting hole 3010 is equal to the outer diameter of the T-shaped column 309.

[0034] The limiting mechanism also includes positioning grooves 403 formed on the inner sidewall of the movable plate 302. The number of positioning grooves 403 is equal to the number of limiting holes 3010, and each positioning groove 403 is located directly above a corresponding limiting hole 3010.

[0035] The positioning block 402 includes a cylinder fixedly connected to the end face of the positioning spring 401, and a hemisphere fixedly connected to the end face of the cylinder. The central axis of the positioning block 402 and the central axis of the positioning groove 403 are located on the same horizontal plane. During the rotation of the movable plate 302, if the positioning groove 403 intersects with the storage groove, the positioning block 402 will be completely retracted into the storage groove, and the positioning spring 401 will be in a compressed state. If the positioning groove 403 is directly opposite the storage groove, the positioning block 402 will be inserted into the positioning groove 403 under the action of the positioning spring 401, making a sound, and one of the limiting holes 3010 will be directly opposite the T-shaped post 309, thereby quickly achieving the positioning effect.

[0036] By placing the air source heat pump fan on top of the anti-slip mat 305 and rotating the movable plate 302 to position the rubber pad 304 above the fan, and then fine-tuning the movable plate 302 until a knocking sound is heard, the positioning block 402, under the action of the positioning spring 401, is inserted into the positioning slot 403, and one of the limiting holes 3010 is aligned with the T-shaped post 309. Then, the T-shaped post 309 is pushed so that the annular magnet 308 disengages from the adsorption range of the right-angle plate 306, and the connecting spring 307 returns to its original position. In its initial state, the T-shaped column 309 is inserted into the limiting hole 3010 to fix the movable plate 302. Then, the threaded rod 303 is rotated to drive the rubber pad 304 to hold the fan, thereby fixing one corner of the fan. Finally, the above operation is repeated to fix all four corners of the fan. Because the rubber pad 304 can move in an arc under the action of the movable plate 302, its position is variable and each rubber pad 304 operates independently, so it can be adapted to fans of different sizes and shapes, and the device has strong applicability.

[0037] Example 2: Figure 1-6As shown, a vibration damping device for an air source heat pump fan includes a support base 1, a fixed platform 2 movably disposed on the top of the support base 1 for supporting the air source heat pump fan, and a spring vibration damper 5 fixedly connected to the inner bottom wall of the support base 1. The top of the spring vibration damper 5 is fixedly connected to the bottom of the fixed platform 2. The device also includes a fixing mechanism fixedly connected to the top of the fixed platform 2, and a limiting mechanism connected to the fixing mechanism. The vibration of the fan during operation is reduced by the spring vibration damper 5.

[0038] The fixing mechanism includes a column 301 fixedly connected to the top of the fixing platform 2 and a movable plate 302 rotatably connected to the outer surface of the column 301 for supporting the fixing components.

[0039] The limiting mechanism includes a storage groove formed on the outer wall of the column 301, a positioning spring 401 fixedly connected to the bottom of the storage groove, and a positioning block 402 fixedly connected to the positioning spring 401 for limiting the movable plate 302.

[0040] The air source heat pump fan is fixed to the top of the fixed platform 2 by the fixing mechanism and the limiting mechanism. When the air source heat pump fan vibrates during operation, the spring shock absorber 5 is used to dampen the vibration, reduce noise, and reduce the wear of the parts caused by vibration.
