Description

Technical Field

[0001] This utility model relates to the field of heat pump unit technology, specifically a vibration reduction and noise reduction structure for heat pump units. Background Technology

[0002] Currently, heat pump units are widely used in building heating and cooling. Many public buildings rely on heat pump units for heating and cooling. Heat pump units have many advantages. Their air conditioning system combines cold and heat sources, eliminating the need for boiler rooms and refrigeration rooms, and eliminating the need for cooling towers, thus saving resources and building investment. However, heat pump units will generate varying degrees of vibration during operation. The more heat pump units there are, the stronger the vibration will be during operation. Therefore, vibration damping installation is generally carried out on heat pump units during installation.

[0003] In the prior art, the utility model patent with publication number CN208794624U discloses an air conditioning thermal power heat pump unit. The rubber shock absorber can effectively reduce the vibration generated by the device during operation, minimizing the impact on the top floor residents. The hydraulic rod can realize the lifting and lowering of the device. With the help of the connecting plate and casters, the device can be moved more easily during installation and transportation. The cooperation between the sliding groove, spring and fixing pin can effectively prevent the baffle from shaking during the movement.

[0004] However, heat pump units generate varying degrees of vibration during operation. The aforementioned technical solutions only install rubber shock absorbers at the four bottom corners of the heat pump unit body, resulting in poor vibration reduction. In addition, the compressor is directly installed inside the main unit body, and noise and vibration are directly transmitted to the direct casing, leading to excessive noise and vibration. Therefore, these solutions do not meet current requirements. To address this, we propose a vibration reduction and noise reduction structure for heat pump units. Utility Model Content

At the same time, the compressor is directly installed in the main body, and the noise and vibration are directly transmitted to the direct housing, resulting in excessive noise and vibration.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vibration damping and noise reduction structure for a heat pump unit, comprising a heat pump unit housing, a groove provided on the lower side of one side of the front end face of the heat pump unit housing, a vibration damping device movably disposed on the inner side of the groove, the vibration damping device comprising a vibration damping seat, a base plate provided on the inner side of the vibration damping seat, retractable sleeve rods installed at the four corners of the lower end face of the base plate, a spring A sleeved on the outer surface of the retractable sleeve rods, and horizontal plates installed at the front and rear of the middle of the lower end face of the base plate, and horizontal plates installed on both the front and rear sides of the upper end face of the vibration damping seat.

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

[0014] 1. This utility model places the air compressor body inside the noise reduction device. When the air compressor body is working, the noise generated is first partially absorbed by the sound-absorbing layer, and the remaining noise enters the noise reduction layer for a second silencing. After the second silencing, the noise is reduced. The remaining noise is consumed by the sound insulation layer, thereby reducing the noise generated when the air compressor body is working. The noise reduction device is installed in the vibration damping device through the base plate. When the air compressor body is working, it will vibrate, which will drive the telescopic sleeve to retract and drive the spring A to extend and retract, buffering the vertical vibration force. The slider slides inside the groove, compressing the spring B. The spring B undergoes elastic deformation, buffering the horizontal vibration force. This utility model installs the air compressor body in the noise reduction device and then in the vibration damping device, thereby achieving the dual effects of buffering and sound insulation, and the vibration and noise reduction effect is good.

[0015] 2. This utility model, by providing a strip-shaped groove and a strip-shaped plate, facilitates the movement of the shock-absorbing device to the outside of the groove. At the same time, the shock-absorbing pipe moves away from the inside of the connecting pipe. By controlling the switch of the electric push rod, the limiting block moves away from the inside of the limiting groove, releasing the limitation on the square shell. At this time, the noise reduction device can be removed from the bottom plate, the bolts can be unscrewed, the air compressor body can be loosened, and the top plate can be removed from the square shell. The top plate and the air compressor body can then be removed from the square shell for inspection and maintenance. Attached Figure Description

[0023] The electric actuator 709 (model LBP40) mentioned in this utility model can be obtained from the market or through private customization.

[0024] Please see Figures 1 to 5 This utility model provides an embodiment of a heat pump unit vibration reduction and noise reduction structure, including a heat pump unit housing 1. A groove 2 is provided on the lower side of one side of the front end face of the heat pump unit housing 1. A vibration damping device 7 is movably arranged inside the groove 2. The vibration damping device 7 includes a vibration damping seat 701. A base plate 9 is provided inside the vibration damping seat 701. Telescopic sleeve rods 708 are installed at the four corners of the lower end face of the base plate 9. Springs A702 are sleeved on the outer surface of the telescopic sleeve rods 708. Horizontal plates 705 are installed at the front and rear of the middle of the lower end face of the base plate 9. Slide grooves 707 are provided on both the front and rear sides of the upper end face of the vibration damping seat 701. The inner side of the slide groove 707... A slider 704 is movably connected to the side via a spring B703. The slider 704 and the horizontal plate 705 are both hinged together via a rotating rod 706. A rubber pad 10 is fixedly connected to the upper end face of the bottom plate 9 via a groove. A noise reduction device 5 is provided above the rubber pad 10. The noise reduction device 5 includes a square shell 506 and a top plate 505. A sound-absorbing layer 501, a noise reduction layer 502, and a sound insulation layer 503 are sequentially provided inside the square shell 506 and the top plate 505. An air compressor body 6 is provided inside the square shell 506. A vibration damping pipe 13 is installed on the upper end face of the air compressor body 6. A connecting pipe 11 is installed above the front end face of the groove 2.

[0025] Furthermore, both sides of the upper surface of the groove 2 are provided with strip grooves 4. The front end face of the strip groove 4 is provided with an opening. A strip plate 8 is movably provided on the opening and the inner side of the strip groove 4. A limit plate is installed on the rear end face of the strip plate 8. The size of the limit plate is larger than the size of the opening. The upper end face of the strip plate 8 is fixedly connected to the lower end face of the shock absorption device 7. When the strip plate 8 moves, it can drive the shock absorption device 7 to move outward from the inner side of the groove 2 and extend out of the groove 2. And by providing a limit plate, the strip plate 8 is prevented from falling off from the inner side of the strip groove 4.

[0026] The telescopic sleeve 708 includes a thick sleeve and a thin sleeve, with the thin sleeve inserted into the inside of the thick sleeve. The upper end face of the spring A702 is fixedly connected to the lower end face of the base plate 9, and the lower end face of the spring A702 is fixedly connected to the inner wall of the shock absorber 701, thereby improving the stability of the telescopic sleeve 708 connection.

[0027] Vertical plates 710 are installed at the four corners of the upper surface of the base plate 9. Electric push rods 709 are installed on the outer surface of the vertical plates 710. Limiting blocks 711 are fixedly connected to the other end of the electric push rods 709. Limiting grooves 504 are provided on the front and back of both sides of the outer surface of the square shell 506. The limiting blocks 711 are adapted to the limiting grooves 504. The limiting blocks 711 can move under the action of the electric push rods 709 to limit the square shell 506 or release the limitation on the square shell 506.

[0028] The shock-absorbing pipe 13 is adapted to the connecting pipe 11. The outer surface of the connecting pipe 11 is fitted with a shock-absorbing sleeve 12. The inside of the shock-absorbing sleeve 12 is filled with shock-absorbing and noise-reducing cotton. Mounting plates are installed on both sides of the outer surface of the air compressor body 6. The mounting plates are connected to the lower end face of the square shell 506 by bolts. When the strip plate 8 is completely inside the strip groove 4, the shock-absorbing pipe 13 can be inserted into the inside of the connecting pipe 11. The shock-absorbing sleeve 12 can reduce the noise of the connecting pipe 11. The bolts can be loosened from the bottom of the square shell 506, thereby disassembling the air compressor body 6.

[0029] The top plate 505 has four corners on its lower end face with inserts, and the square housing 506 has four corners on its upper end face with slots. The inserts are inserted into the inside of the slots. The inserts are fixed to the square housing 506 with screws, and the top plate 505 can be removed from the square housing 506.

[0030] A single door 3 is rotatably connected to the inner side of the groove 2 via a hinge.

Heat dissipation grooves are provided on both sides of the outer surface of the heat pump unit housing 1, and a dustproof net is installed on the inner side of the heat dissipation grooves.

[0031] When the heat pump unit is in use, the power is first turned on. By placing the air compressor body 6 inside the noise reduction device 5, the noise generated by the air compressor body 6 during operation is first absorbed by the sound absorption layer 501. The remaining noise enters the noise reduction layer 502 for a second round of noise reduction. After the second round of noise reduction, the noise is reduced. The remaining noise is consumed by the sound insulation layer 503, thereby reducing the noise generated by the air compressor body 6 during operation.

[0032] The noise reduction device 5 is installed in the shock absorption device 7 through the base plate 9. When the air compressor body 6 is working, it will generate vibration, which will drive the telescopic sleeve rod 708 to retract and drive the spring A702 to extend and retract, thus buffering the vertical vibration force. The slider 704 slides on the inner side of the slide groove 707, squeezing the spring B703. The spring B703 undergoes elastic deformation, thus buffering the horizontal vibration force. Furthermore, by providing the strip groove 4 and the strip plate 8, it is convenient to move the shock absorption device 7 to the outside of the groove 2. At the same time, the anti-vibration tube 13 leaves the inner side of the connecting tube 11. By controlling the switch of the electric push rod 709, the limit block 711 leaves the inner side of the limit groove 504, thus releasing the limit on the square shell 506.

[0033] At this point, the noise reduction device 5 can be removed from the base plate 9. The bolts can be unscrewed to loosen the air compressor body 6, and then the top plate 505 can be removed from the square housing 506. The top plate 505 and the air compressor body 6 can then be removed from the square housing 506 for maintenance. This utility model installs the air compressor body 6 inside the noise reduction device 5 and then inside the shock absorption device 7, thereby achieving a dual effect of buffering and sound insulation. It has a good shock absorption and noise reduction effect and facilitates the maintenance of the air compressor body 6.

[0034] For those skilled in the art, this utility model is not limited to the above-described embodiments. If various modifications or variations to this utility model do not depart from the spirit and scope of this utility model, and if these modifications and variations fall within the scope of the claims and equivalent technologies of this utility model, then this utility model also intends to include these modifications and variations.
