Abstract

This utility model relates to the technical field of air source heat pump buffer mechanisms, and provides a high-efficiency damping and vibration reduction mechanism for air source heat pumps. The mechanism includes an air source heat pump, a connecting plate connected to the bottom of the air source heat pump, a buffer assembly connected to the bottom of the connecting plate, and a waterproof and breathable membrane connected to the top of the connecting plate. In this utility model, when the air source heat pump vibrates, the top plate is pressured, causing the fixed block to move downwards. The telescopic rod compresses the first spring, and the damper quickly attenuates the vibration energy, reducing reciprocating oscillations. During the downward movement of the fixed block, the push rod pushes the movable block to slide along the connecting rod, causing the second spring to deform under force, further absorbing vibration energy in both horizontal and inclined directions.

Description

Technical Field

[0001] This utility model belongs to the technical field of air source heat pump buffer mechanism, and particularly relates to a high-efficiency damping and shock absorption mechanism for air source heat pumps. Background Technology

[0002] Air source heat pumps, as an energy-saving and environmentally friendly heating and hot water supply device, have been widely used in the context of global energy transition and low-carbon development. With their high efficiency, energy saving, environmental protection and low carbon characteristics, air source heat pumps are widely used in heating, cooling and hot water supply fields around the world. Whether in residential buildings, providing residents with a comfortable heating and cooling environment and domestic hot water, or in commercial buildings, such as hotels and shopping malls, meeting their large-scale heating and cooling needs, air source heat pumps have demonstrated good applicability and economy.

[0003] For example, Chinese Patent (Publication No.: CN218031250U) discloses an air source heat pump with damping and vibration reduction, including an air source heat pump and damping vibration dampers. Its features include: a heat pump vibration reduction support base at the bottom of the air source heat pump; a heat pump heat exchange fan at the center of the top of the air source heat pump; a heat pump finned heat exchanger on the upper left side of the air source heat pump; heat pump inlet and outlet water pipes on the right side of the air source heat pump; and several damping vibration dampers fixed at the lower part of the heat pump vibration reduction support base. This solves the problems of vibration and noise from the air source heat pump disturbing residents' daily rest and affecting building structures after operation. However, this device has limitations in vibration reduction effect and a narrow range of application. It only uses a single longitudinal spring for buffering, making it difficult to effectively absorb vibration energy from different directions and frequencies. During vibration, it is prone to reciprocating oscillations and cannot quickly stabilize the device. Therefore, a high-efficiency damping vibration reduction mechanism for air source heat pumps is needed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a high-efficiency damping and vibration reduction mechanism for an air source heat pump to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-efficiency damping and shock absorption mechanism for an air source heat pump includes an air source heat pump, a connecting plate connected to the bottom of the air source heat pump, a buffer assembly connected to the bottom of the connecting plate, a waterproof and breathable membrane connected to the top of the connecting plate, and a sealing ring connected to the connection between the connecting plate and the air source heat pump.

[0007] The buffer assembly includes a top plate, a fixed block connected to the bottom of the top plate, a telescopic rod connected to the bottom of the fixed block, a first spring connected to the bottom end of the telescopic rod, a damper sleeved inside the first spring, and a hollow rod sleeved outside the first spring. There are two hollow rods, and a connecting block connects the two hollow rods. Connecting rods are welded to both sides of the connecting block, and a movable block is movably connected to the outside of the connecting rod. A push rod connects the fixed block and the movable block, and a second spring sleeved outside the connecting rod.

[0008] In a further technical solution, there are two fixed blocks and two telescopic rods, one of which has a base plate connected to its bottom, and four buffer components.

[0009] In a further technical solution, each of the fixed blocks is rotatably connected to one end of a push rod on both sides, and the top and bottom of the connecting rod are connected to a connecting shaft. The other end of the push rod is connected to the connecting shaft, and the number of push rods is four.

[0010] In a further technical solution, one end of the connecting rod is connected to a limiting plate, one end of the second spring is connected to the limiting plate, and the other end of the second spring is connected to a movable block. The number of the connecting rod, the second spring, and the movable block are all two.

[0011] In a further technical solution, the connecting plate and the air source heat pump are connected by a second fixing bolt via a thread. Threaded grooves are provided at the four corners of the connecting plate, and the threaded grooves are connected to the second fixing bolt.

[0012] In a further technical solution, the top plate and the connecting plate are connected by a first fixing bolt via a thread. The connecting plate is shaped like a grid, and a buffer pad is connected inside the connecting plate. The buffer pad is honeycomb shaped.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] Through the synergistic effect of multiple damping structures, efficient absorption and dissipation of vibration energy are achieved. When the air source heat pump vibrates, the top plate is pressured, causing the fixed block to move downward. The telescopic rod compresses the first spring, while the damper can quickly attenuate the vibration energy and reduce reciprocating oscillations. During the downward movement of the fixed block, the push rod pushes the movable block to slide along the connecting rod, causing the second spring to deform under force, further absorbing the vibration energy in the horizontal and inclined directions. This multi-directional and multi-level damping design effectively copes with vibrations of different frequencies and directions, greatly improves the stability of equipment operation, reduces the risk of loosening and wear of parts due to vibration, and extends the service life of the equipment.

[0015] In this invention, the waterproof and breathable membrane on the top of the connecting plate not only prevents external moisture, dust, and other impurities from entering the air source heat pump, but also ensures air circulation inside the equipment, preventing damage to components due to moisture caused by a sealed environment. The sealing ring at the connection between the connecting plate and the air source heat pump further enhances the sealing effect and prevents moisture penetration. In addition, the grid-shaped connecting plate has a honeycomb-shaped buffer pad inside. The honeycomb structure has good buffering and support performance, which can further absorb vibration and effectively protect the bottom of the equipment, reducing the direct impact of vibration on the equipment body, thereby extending the service life of the equipment.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] like Figures 1-4As shown, this utility model embodiment provides a high-efficiency damping and shock absorption mechanism for an air source heat pump, including an air source heat pump 1, a connecting plate 2 connected to the bottom of the air source heat pump 1, a buffer assembly 3 connected to the bottom of the connecting plate 2, a waterproof and breathable membrane 4 connected to the top of the connecting plate 2, and a sealing ring 5 connected to the connection between the connecting plate 2 and the air source heat pump 1.

[0025] The buffer assembly 3 includes a top plate 301, a fixed block 302 connected to the bottom of the top plate 301, a telescopic rod 303 connected to the bottom of the fixed block 302, a first spring 304 connected to the bottom end of the telescopic rod 303, a damper 305 sleeved on the inner side of the first spring 304, and a hollow rod 306 sleeved on the outer side of the first spring 304. There are two hollow rods 306, and a connecting block 307 is connected between the two hollow rods 306. Connecting rods 308 are welded to both sides of the connecting block 307. A movable block 309 is movably connected to the outer side of the connecting rod 308. A push rod 310 is connected between the fixed block 302 and the movable block 309. A second spring 311 is sleeved on the outer side of the connecting rod 308.

[0026] In this embodiment, when the vibration energy is transmitted to the top plate 301 of the buffer assembly 3 via the connecting plate 2, the top plate 301 transmits the force to the bottom fixing block 302. After being subjected to force, the fixing block 302 moves downward, causing the telescopic rod 303 to retract into the hollow rod 306. At this time, the first spring 304 connected to the bottom end of the telescopic rod 303 is compressed. The first spring 304 absorbs the vertical vibration energy through its own deformation. At the same time, the damper 305 sleeved inside the first spring 304 plays a damping role, using the viscous resistance of its internal damping medium to quickly attenuate the elasticity of the first spring 304. To prevent continuous vibration caused by the reciprocating extension and contraction of the spring, and to achieve efficient suppression of vertical vibration, during the downward movement of the fixed block 302, the push rods 310 connected to its two sides push the movable block 309 to slide along the connecting rod 308 to both sides. When the movable block 309 slides, it will squeeze the second spring 311 sleeved on the outside of the connecting rod 308. The second spring 311 absorbs the horizontal vibration energy through deformation, while the limiting plate 8 at one end of the connecting rod 308 can limit the sliding range of the movable block 309, prevent it from detaching from the connecting rod 308, and ensure the stable operation of the horizontal vibration damping structure.

[0027] like Figure 2 , Figure 3 and Figure 4 As shown, specifically, there are two fixed blocks 302 and two telescopic rods 303, one of which has a base plate 12 connected to its bottom, and four buffer components 3.

[0028] Each fixed block 302 is rotatably connected to one end of a push rod 310 on both sides. The top and bottom of the connecting rod 308 are connected to the connecting shaft 9. The other end of the push rod 310 is connected to the connecting shaft 9. There are four push rods 310.

[0029] One end of the connecting rod 308 is connected to the limiting plate 8, one end of the second spring 311 is connected to the limiting plate 8, and the other end of the second spring 311 is connected to the movable block 309. There are two connecting rods 308, two second springs 311 and two movable blocks 309.

[0030] The connecting plate 2 and the air source heat pump 1 are connected by a second fixing bolt 11 through a thread. The four corners of the connecting plate 2 are provided with threaded grooves 6, which are connected to the second fixing bolt 11.

[0031] The top plate 301 and the connecting plate 2 are connected by a first fixing bolt 10 through a thread. The connecting plate 2 is shaped like a grid, and a buffer pad 7 is connected inside the connecting plate 2. The buffer pad 7 is honeycomb shaped.

[0032] In this embodiment, when the air source heat pump 1 vibrates during operation, the vibration energy is first transferred to the bottom connecting plate 2. The honeycomb buffer pad 7 inside the grid-shaped connecting plate 2 will initially absorb and buffer the vibration, and use the deformation characteristics of the honeycomb structure to disperse some of the vibration energy, reducing the direct impact of vibration on the subsequent structure. The waterproof and breathable membrane 4 on the top of the connecting plate 2 continues to play a role throughout the entire operation, preventing external moisture and dust from entering the air source heat pump 1, and ensuring air circulation inside the equipment, avoiding the impact on the equipment's operating environment due to seal failure caused by vibration. The sealing ring 5 at the connection between the connecting plate 2 and the air source heat pump 1 further enhances the sealing of the connection, preventing problems such as air leakage and water seepage caused by vibration.

[0033] The working principle of this utility model is as follows: First, when the air source heat pump 1 vibrates during operation, the vibration energy is first transmitted to the bottom connecting plate 2. The honeycomb buffer pad 7 inside the grid-shaped connecting plate 2 will initially absorb and buffer the vibration, dispersing some of the vibration energy by utilizing the deformation characteristics of the honeycomb structure. Then, when the vibration energy is transmitted to the top plate 301 of the buffer assembly 3 via the connecting plate 2, the top plate 301 transmits the force to the bottom fixing block 302. After being subjected to force, the fixing block 302 moves downward, causing the telescopic rod 303 to retract into the hollow rod 306. At this time, the first... When spring 304 is compressed, the first spring 304 absorbs the vertical vibration energy through its own deformation. At the same time, the damper 305, which is fitted inside the first spring 304, plays a damping role. By utilizing the viscous resistance of its internal damping medium, the elastic vibration of the first spring 304 is rapidly attenuated. Finally, as the fixed block 302 moves down, the push rods 310 connected to its two sides push the movable block 309 to slide along the connecting rod 308 to both sides. When the movable block 309 slides, it will squeeze the second spring 311 fitted outside the connecting rod 308. The second spring 311 absorbs the horizontal vibration energy through deformation.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
