DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] In the description of the present invention, it should be noted that the terms "vertical direction", "upper", "lower", "horizontal" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0038] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, a mechanical connection, an electrical connection, a direct connection, or a connection through an intermediate medium, or the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] The heat pump compressor is one of the core components of the heat pump. It is heavy and will generate large vibrations and noises during actual use and operation. The heat pump will also cause transportation vibrations of the compressor during transportation after leaving the factory, and the pipelines connected to the compressor will also vibrate. The vibration and bumps of the compressor during transportation are often much more severe than its operating vibrations, which often lead to the rupture of the compressor pipeline.

[0040] The research on compressor vibration reduction in the prior art mainly focuses on vibration reduction during the operation of the compressor. The vibration reduction method is often to set vibration reduction components such as foot pads between the compressor and the base plate, or to add a compressor cover and a compressor outer sponge, etc. to the compressor. This vibration reduction method is not ideal and cannot overcome the large vibrations generated during transportation.

[0041] See also Figure 1 and Figure 2 The present embodiment provides a transport vibration reduction structure for a compressor, comprising: a compressor 10, a base plate 20, and a vibration reduction mechanism 30 connecting the compressor 10 and the base plate 20, wherein the compressor 10 and the base plate 20 are flexibly connected by the vibration reduction mechanism 30 to reduce vibration and noise generated during the operation of the compressor 10. The vibration reduction mechanism 30 is provided with a first vibration reduction assembly 31 and a second vibration reduction assembly 32, wherein the second vibration reduction assembly 32 comprises a chassis 321 and a vibration reduction pad 322, wherein the compressor 10 is fixedly connected to the chassis 321 through the first vibration reduction assembly 31, and the chassis 321 is fixedly connected to the base plate 20 through the vibration reduction pad 322, thus, the first vibration reduction assembly 31 and the second vibration reduction assembly 32 realize a flexible connection between the compressor 10 and the base plate 20 to reduce vibration during the operation and transportation of the compressor 10.

[0042] Furthermore, the first vibration reduction assembly 31 includes a rubber pad and a screw pair. The rubber pad is arranged between the compressor 10 and the chassis 321 . The screw pair passes through the rubber pad to lock the compressor 10 between the chassis 321 .

[0043] Furthermore, in some embodiments, the transport vibration reduction structure of the compressor further includes a fixing member 40, which is arranged at intervals along the outer periphery of the chassis 321. The outer periphery of the chassis 321 is surrounded by a plurality of planes and / or curved surfaces, and the fixing member 40 is arranged at the bend of the outer periphery of the chassis 321, one end of which is detachably connected to the chassis 321, and the other end is detachably connected to the bottom plate 20, thereby realizing a rigid connection between the chassis 321 and the bottom plate 20, so as to overcome the large vibration caused by the bumps of the compressor 10 during transportation, which may cause the compressor 10 to break from the pipeline.

[0044] It can be understood that the detachable connection between the fixing member 40 and the chassis 321 and the base plate 20 can be locked or unlocked by a locking member. The locking member can be a common bolt. A plurality of bolts lock one end of the fixing member 40 to the chassis 321 at intervals, and at the same time, a plurality of bolts lock the other end of the fixing member 40 to the base plate 20 at intervals.

[0045] In the embodiment of the present application, the fixing member 40 is arranged at the bend of the chassis 321, so that the fixing member 40 can resist the impact forces in multiple horizontal directions caused by the vibration of the compressor 10. The fixing member 40 can fix the chassis 321 in multiple directions, and the number of fixing members 40 used can be reduced to achieve the same full-circle protection effect. In addition, when the compressor 10 applies a horizontal force to one end of the fixing member 40, this end vertically resists the force, and the other end connected to it will also provide a pulling force to assist in resisting the force from the compressor 10, which has a better vibration reduction effect and is more conducive to transportation scenarios.

[0046] See also Figure 1-3 Further, in some embodiments, the fixing member 40 is provided with an abutting portion 42 to abut against the side wall surface at the bend of the chassis 321, and an upper fixing portion 41 and a lower fixing portion 43 are respectively extended at both ends thereof, the upper fixing portion 41 is locked to the upper end surface of the chassis 321, and the lower fixing portion 43 is locked to the upper end surface of the bottom plate 20. Preferably, the cross-sectional shape of the fixing member 40 is Z-shaped, wherein the shape of the abutting portion 42 is consistent with the shape of the bend of the chassis 321 abutted therewith, so that the abutting portion 42 can be well covered at the bend of the chassis 321, so as to increase the contact area between the abutting portion 42 and the chassis 321, thereby improving the impact resistance of the fixing member 40 and improving the stability of the compressor 10.

[0047] In some embodiments, the chassis 321 is a polygon, and its outer side wall is surrounded by multiple planes, and the abutment portion 42 includes at least two straight edges, so that the fixing member 40 is sleeved on the outside of one of the bends of the chassis 321. As an example, in this embodiment, the abutment portion 42 is provided with two straight edges, which are respectively abutted against two adjacent wall surfaces of the chassis 321. Under this arrangement, it is only necessary to respectively set the fixing members 40 at the two diagonal portions of the chassis 321 to achieve a rigid connection between the chassis 321 and the bottom plate 20. Preferably, the angle between the two adjacent straight edges is greater than 90°. It is understandable that the abutment portion 42 can also be provided with three straight edges, while covering two adjacent bends of the chassis 321. It will not be described in detail here.

[0048] Furthermore, in some embodiments, the fixing member 40 is an integrally formed sheet metal structure, and the upper fixing portion 41 and the lower fixing portion 43 are provided with cutouts 44 at positions corresponding to the bends of the abutting portion 42, so as to overcome the material extrusion accumulation or tensile cracking during the sheet metal stamping process, thereby avoiding uneven thickness of the upper fixing portion 41 and the lower fixing portion 43 caused by the sheet metal being extended and bent, thereby affecting the rigidity of the fixing member 40. The cutouts 44 divide the upper fixing portion 41 into a plurality of upper fixing blocks that are individually connected to the abutting portion 42, and each upper fixing block is individually locked to the upper end surface of the chassis 321 through a locking member; the cutouts 44 divide the lower fixing portion 43 into a plurality of lower fixing blocks that are individually connected to the abutting portion 42, and the lower fixing blocks are individually locked to the upper end surface of the bottom plate 20 through locking members.

[0049] In some other embodiments, the chassis 321 is circular and the abutment 42 is arc-shaped. Preferably, the central angle of the arc-shaped abutment 42 is 60-90°. Within this angle range, the size of the fixing member 40 is small, and the fixing member 40 can be set only at two opposite arcs of the chassis 321, which can resist the impact forces in multiple horizontal directions and effectively reduce vibration; at the same time, the number of fixing members 40 can be saved, and the assembly and disassembly time can also be saved. In this setting mode, the fixing member 40 can be a sheet metal structure integrally formed, or it can be a casting or forging, etc. Taking the sheet metal structure as an example, the upper fixing part 41 is provided with at least one cutout 44 to divide the upper fixing part 41 into at least two upper fixing blocks, and each upper fixing block is respectively locked to the upper end surface of the chassis 321 by a locking member. The lower fixing part 43 is provided with at least one cutout 44 to divide the lower fixing part 43 into at least two lower fixing blocks, and each lower fixing block is respectively locked to the upper end surface of the floor by a locking member.

[0050] See also Figure 4-7 Furthermore, in some embodiments, the transport vibration reduction structure of the compressor also includes: an upper positioning structure 51, the upper positioning structure 51 is provided with an upper positioning column 511 and an upper buckle position 512 that cooperate with each other, one of which is provided on the upper fixing portion 41, and the other is provided on the chassis 321; the upper positioning column 511 is inserted into the upper buckle position 512 to realize rapid positioning of the fixing member 40 and the chassis 321 before locking.

[0051] In some other embodiments, the transport vibration reduction structure of the compressor may also include: a lower positioning structure 52, the lower positioning structure 52 is provided with a matching lower positioning column 521 and a lower buckle position 522, one of which is provided on the lower fixing portion 43, and the other is provided on the bottom plate 20; the lower positioning column 521 is inserted into the lower buckle position 522 to achieve rapid positioning of the fixing member 40 and the bottom plate 20 before locking.

[0052] See also Figure 7As an example, the upper positioning column 511 is provided on the upper fixing portion 41, protruding toward the chassis 321, and the upper buckle position 512 is provided on the chassis 321; the lower positioning column 521 is provided on the lower fixing portion 43, protruding toward the bottom plate 20, and the lower buckle position 522 is provided on the bottom plate 20. When installing the fixing member 40, the upper positioning column 511 is first inserted into the upper buckle position 512, and the lower positioning column 521 is inserted into the lower buckle position 522. At this time, the upper fixing portion 41 is aligned with the mounting hole position on the chassis 321, and the lower fixing portion 43 is aligned with the mounting hole position on the bottom plate 20. The upper fixing portion 41 is locked on the chassis 321 by the locking member, and the lower fixing portion 43 is locked on the bottom plate 20, so as to realize the rigid connection between the chassis 321 and the bottom plate 20.

[0053] See also Figure 5 and Figure 6 Further, in some embodiments, the vibration-damping foot pads 322 are a plurality of elastic pads, such as rubber pads, evenly spaced between the chassis 321 and the bottom plate 20. The vibration-damping foot pads 322 are provided with screws, the two ends of which are respectively fixed to the chassis 321 and the bottom plate 20, and the two end surfaces of the vibration-damping foot pads 322 are elastically abutted against the chassis 321 and the bottom plate 20 to achieve a flexible connection between the two.

[0054] Preferably, the number of the vibration-damping pads 322 is greater than or equal to 3, so that the fixed connection between the chassis 321 and the base plate 20 can be better achieved through the screws. Preferably, the height of the vibration-damping pads 322 is 20-30 mm. If the height of the vibration-damping pads 322 is too low, its elastic deformation ability is relatively weak. If the height is too high, the distance between the compressor 10 and the base plate 20 will be too large, and the elastic deformation of the vibration-damping pads 322 will be too large, which will increase the instability factor. Preferably, the contact area S1 between the vibration-damping pads 322 and the chassis 321 is 1 / 3-3 / 4 of the contact surface area S2 of the chassis 321. Within this contact area range, the vibration-damping pads 322 can maintain good elastic deformation performance while bearing the gravity of the compressor 10, and its anti-vibration performance is good.

[0055] Furthermore, the second vibration reduction assembly 32 is also provided with a multi-layered sound-absorbing structure 323, which is arranged between the chassis 321 and the bottom plate 20, and the vibration reduction pad 322 is embedded in the multi-layered sound-absorbing structure 323, and the thickness of the vibration reduction pad 322 is greater than the thickness of the multi-layered sound-absorbing structure 323, and the thickness difference between the two is 2-4 mm, so that when the compressor 10 is installed on the chassis 321, the vibration reduction pad 322 is compressed under the gravity of the compressor 10, and the multi-layered sound-absorbing structure 323 just abuts against the bottom plate 20, playing a supplementary supporting role for the chassis 321. Preferably, the side wall of the suspended bottom plate 20 is a sheet metal flange structure, and the flange is surrounded to form a trough body, and the vibration reduction pad 322 and the multi-layered sound-absorbing structure 323 are arranged inside the trough body, and one end face of the multi-layered sound-absorbing structure 323 is attached to the inner bottom surface of the trough body. Thus, a noise reduction combined unit of chassis 321 - multi-layer sound-absorbing structure 323 - bottom plate 20 is formed.

[0056] See also Figure 6 Specifically, the multi-layer sound-absorbing structure 323 is provided with a damping layer 3231, a porous layer 3233, and a buffer layer 3232 arranged between the damping layer 3231 and the porous layer 3233; the damping layer 3231 is attached to the bottom of the chassis 321, and the porous layer 3233 is arranged close to the bottom plate 20. After the compressor 10 is installed, due to the gravity of the compressor 10, the vibration-damping foot pad 322 is compressed and deformed, and the porous layer 3233 can abut against the bottom plate 20.

[0057] As an example, the damping layer 3231 can be butyl damping glue, which is attached to the bottom surface of the chassis 321 to reduce the noise and vibration of the chassis 321 and convert it into self-heat energy dissipation. The buffer layer 3232 can be a rubber interlayer. When the noise sound wave reaches the buffer layer 3232, due to the different natural frequencies of the buffer layer 3232 and the damping layer 3231, the sound wave that the damping layer 3231 fails to filter out can be further filtered, and then converted into self-heat energy dissipation. The porous layer 3233 can be a porous polymer material or a porous structure material such as fiber felt. Due to its porous structure, the sound wave causes air vibration and fiber friction in it, thereby reducing the operating noise of the compressor 10. The unprocessed residual noise of the multi-layer silencing structure 323 will be further reduced when passing through the base plate 20.

[0058] See also Figure 1Furthermore, the transport vibration reduction structure of the compressor is also provided with a press cover 11 and a sponge 12, which are used to reduce the noise generated during the operation of the compressor 10. The press cover 11 is arranged on the outside of the compressor 10, and its end is fixed to the chassis 321. Specifically, a protruding hook 111 is provided at the bottom of the press cover 11, and the hook 111 is inserted into the chassis 321 to position and limit the press cover 11. A folded edge 112 is also provided at the bottom of the press cover 11, and the folded edge 112 is locked to the chassis 321 by a locking member. The sponge 12 is arranged between the compressor 10 and the press cover 11, which is used for further silencing and noise reduction, which will not be described in detail here.

[0059] The embodiment of the present application also provides a heat pump, which is provided with the above-mentioned compressor transportation vibration reduction structure, which can effectively reduce the vibration of the compressor during operation and transportation, especially to overcome the severe vibration caused by bumps during transportation.

[0060] Compared with the prior art, the beneficial effects of the embodiments of the present application are:

[0061] (1) By setting fixings at the bend of the chassis to achieve a rigid connection between the chassis and the bottom plate, the impact force of the compressor in multiple horizontal directions caused by severe bumps during transportation can be better resisted, thereby preventing the compressor pipeline from breaking;

[0062] (2) By using bent fixings, the number of fixings can be reduced, which facilitates production and installation and simplifies the debugging operation after the installation of the unit project;

[0063] (3) A vibration reduction mechanism with a chassis is provided between the compressor and the base plate to achieve a flexible connection between the compressor and the base plate, thereby reducing vibration noise of the compressor during operation and transportation.

[0064] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and the utility model is also intended to include these modifications and modifications.
