[0002] Air source heat pumps use the heat in the air to generate heat energy. They can provide the whole family with different hot water, cooling and heating needs with large water volume, high water pressure and constant temperature 24 hours a day, while meeting the above requirements with the least energy consumption.

[0003] The air heat pump provides heat source through the reverse Carnot principle, compresses the refrigerant through the compressor to increase its temperature, and passes the refrigerant through the condenser in the water tank to produce hot water. Since the compressor and inverter are used as conversion equipment, the compressor and other components will generate a lot of noise when working. Although the water tank and the compressor components will be deliberately separated when installing the air heat pump, and the compressor will be external to reduce the noise impact, the external compressor still has noise pollution. At the same time, the external pipes of the compressor are interspersed in the house. When the liquid in the pipe flows, it will impact the pipe, causing the pipe to vibrate, and then it will also generate a lot of noise. Therefore, a noise reduction structure of the air energy heat pump is needed to solve the above problems. Summary of the invention

When the air thermal energy pump box generates noise during operation, the gaps between the sound absorbing box body and the inner lining box can effectively absorb the sound waves, so that the sound waves are repeatedly refracted in the cavity between the sound absorbing box body and the inner lining box until they are eliminated.

[0009] Preferably, the air thermal energy pump housing is connected to fixed seats at the four corners, and the side of the fixed seat is embedded with a limit block installed through a groove. The limit block is fixed at the corner of the sound insulation board, and the limit block is limited by the groove of the fixed seat to prevent the sound insulation board from shaking left and right during use and generating noise.

[0010] Preferably, a fixed plug rod is provided at the top of the fixed seat, and the fixed plug rod consists of a disc end and an insertion shaft end. The insertion shaft end of the fixed plug rod passes through the fixed seat and the interior of the limit block through a through hole.

The right guide ring plate and the left cutting ring plate are symmetrically arranged, and the length of the left cutting ring plate is shorter than that of the right guide ring plate. When noise is generated, the right guide ring plate and the left cutting ring plate on the inner wall of the inner liner tube can refract the sound waves, and then repeatedly refract and reduce the sound waves generated when the liquid flows, thereby ensuring the sound-absorbing and noise-reducing effect of the external sleeve.

[0013] Preferably, the monitoring component includes a pressure pad ceramic ring installed on the outside of the circulation pump pipeline, a vibration sensor is arranged on the top of the pressure pad ceramic ring, and the vibration sensor is connected to a rectifier through a wiring harness, the rectifier is connected to a pipeline detection instrument through a wiring harness, and the pipeline detection instrument is fixed to the outside of the sound insulation board by bolts. The vibration sensor can capture tiny vibrations of the pipeline, and the vibration sensor is installed at the place with the strongest noise on the right side of the circulation pump to maximize energy collection.

[0014] The present invention has at least the following beneficial effects: 1. By setting up a noise reduction panel group, the noise reduction treatment of the air thermal energy pump box is achieved. Compared with the traditional structure, this device is rotatably installed on the four sides of the air thermal energy pump box through the sound insulation board. The sound insulation board adopts a flip-up design, which is also convenient for the staff to inspect and repair the air thermal energy pump box. When the sound insulation board is placed upright on the outside of the air thermal energy pump box, the noise is absorbed by the sound-absorbing box body. There are pores on the surface of the sound-absorbing box body and the inner lining box. When sound waves enter these pores, the sound energy will be converted into heat energy, thereby reducing the intensity of the sound waves. Sound-absorbing cotton strips are installed inside the inner lining box. Through the design of the sound-absorbing cotton strips, the noise sound waves are further reduced to ensure the noise reduction effect.

[0015] 2. By setting up the sound insulation board and the rubber board, when the device is rotated and placed on the side of the air thermal energy pump box, the rubber board is in contact with the outside of the air thermal energy pump box, and a cavity is formed between the air thermal energy pump box and the sound insulation board. At this time, the sound insulation board and the sound absorbing box group cooperate to absorb sound and reduce noise, while the external flow wind can be blown from the cavity of the air thermal energy pump box and the sound absorbing box group, effectively reducing the heat dissipation effect of the heat dissipation holes on the outside of the air thermal energy pump box, avoiding the traditional mask-type noise reduction, and affecting the air circulation in the air thermal energy pump box.

[0016] 3. By setting up a pipe group, the noise generated by the flow of liquid in the connecting pipe can be further reduced. The device can be connected with another threaded sleeve on the right side of one of the external sleeves, and multiple external sleeves can be connected and installed on the surface of the connecting pipe to adapt to the length of the connecting pipe. At this time, the noise waves generated by the flow of liquid in the connecting pipe are repeatedly refracted by the right guide ring plate and the left cutting ring plate on the inner wall of the inner lining pipe to perform noise reduction operations. The left cutting ring plate and the right guide ring plate cooperate to reflect part of the sound waves back to reduce the penetration of sound waves, and form a sound-absorbing cavity between the inner lining pipe and the external sleeve. An annular sound-absorbing cotton is installed in the sound-absorbing cavity. The annular sound-absorbing cotton has a porous structure. When sound waves enter these pores, the sound energy will be converted into heat energy, further reducing the noise intensity when the liquid flows in the strength connecting pipe.

[0017] 4. By setting up monitoring components, the pipeline status of the connecting pipe can be detected. This device is installed on the pipeline surface on the right side of the circulation pump through a pressure pad ceramic ring. The tiny vibration of the pipeline can be captured by the vibration sensor. The vibration sensor is installed at the place where the noise is strongest on the right side of the circulation pump to maximize energy collection. At this time, the vibration sensor can convert the vibration of the pipeline into its own mechanical vibration. When the pressure pad ceramic ring senses mechanical stress, it will generate charges when subjected to mechanical stress. These charges can be converted into electrical energy through the circuit. The charges generated by the pressure pad ceramic ring are transmitted to the energy storage device through the wire, and the rectifier is used to convert the alternating current into direct current, and the voltage stabilizer is used to maintain the stability of the output voltage. The electrical energy converted from the vibration noise of the connecting pipe is used to ensure the normal operation of the pipeline detection instrument. The use status of the connecting pipe can be monitored through the pipeline detection instrument. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] A fixed plug rod 27 is arranged at the top of the fixed seat 26. The fixed plug rod 27 consists of a disc end and an insertion shaft end. The insertion shaft end of the fixed plug rod 27 passes through the fixed seat 26 and the inside of the limit block 25 through a through hole. A rubber ring is arranged on the surface of the insertion shaft end of the fixed plug rod 27.

The right guide ring plate 324 and the left cutting ring plate 325 are symmetrically arranged, and the length of the left cutting ring plate 325 is shorter than that of the right guide ring plate 324 .

[0029] The outer side of the inner lining tube 323 is connected to the outer sleeve 321, a sound absorbing cavity is arranged between the outer sleeve 321 and the inner lining tube 323, the inner wall of the inner lining tube 323 is provided with pores, annular sound absorbing cotton 326 is installed in the sound absorbing cavity of the inner lining tube 323 and the outer sleeve 321, a threaded ring 322 is connected to the left side of the external sleeve 321, and an external thread matching the threaded ring 322 is arranged on the right side of the external sleeve 321.

[0030] The monitoring component 5 includes a pressure pad ceramic ring 51 installed on the outside of the pipeline of the circulation pump 4. A vibration sensor 52 is arranged on the top of the pressure pad ceramic ring 51, and the vibration sensor 52 is connected to a rectifier 53 through a wiring harness. The rectifier 53 is connected to a pipeline detection instrument 54 through a wiring harness, and the pipeline detection instrument 54 is fixed to the outside of the sound insulation board 21 by bolts.

[0031] The sound insulation board 21 can be movably connected to the top side of the air heat energy pump box 1. By lifting up the sound insulation board 21, the heat sink and the door panel of the air heat energy pump box 1 can be easily exposed. At this time, it is convenient for the staff to disassemble the heat sink and the door panel, ensuring the convenience of the staff to inspect and repair the electrical components inside the air heat energy pump box 1. The design of multiple sound-absorbing box groups 24 on the inner wall of the sound insulation board 21 can effectively reduce the noise generated by the operation of the air heat energy pump box 1. The inclined design of the top of the sound insulation board 21 can make the four sound insulation boards 21 form a surrounding trend on the air heat energy pump box 1, and at the same time prevent the heat dissipation fan of the air heat energy pump box 1 from being blocked. When the sound insulation board 21 is placed vertically, the rubber plate 23 can contact the surface of the air heat energy pump box 1 to prevent the vibration generated when the air heat energy pump box 1 is working from driving the sound insulation board 21 to swing and vibrate, thereby reducing the air The probability of the heat pump box body 1 vibrating and generating noise is reduced. When the sound insulation board 21 is rotated and placed above the connecting pipe 31, the rubber pad 28 arranged at the groove of the sound insulation board 21 can prevent the sound insulation board 21 from colliding with the connecting pipe 31. At the same time, when the rubber pad 28 is installed, the side convex block end of the rubber pad 28 can be embedded in the groove of the sound insulation board 21 to ensure the stability of the installation of the rubber pad 28. A double-layer sandwich cavity can be formed by cooperating with the sound-absorbing box body 241 and the lining box 242. When the air heat pump box body 1 generates noise during operation, the pores of the sound-absorbing box body 241 and the lining box 242 can effectively absorb the sound waves, so that the sound waves are repeatedly refracted in the sandwich cavity between the sound-absorbing box body 241 and the lining box 242 until they are reduced. At the same time, the sound-absorbing cavity of the sound-absorbing box body 241 has a built-in sound-absorbing cotton strip 243, which can absorb the noise sound waves after reduction, thereby ensuring the reduction effect of the sound waves.

[0032] When the sound insulation board 21 is rotated and placed upright on the side of the air heat energy pump housing 1, the sound insulation board 21 pushes the limit block 25 to move and be inserted into the groove of the fixing seat 26. The limit block 25 is limited by the groove of the fixing seat 26 to prevent the sound insulation board 21 from shaking left and right and generating noise during use. When the limit block 25 is installed in the groove of the fixing seat 26, the axial end of the fixed insertion rod 27 can pass through the fixing seat 26 and be inserted into the through hole of the limit block 25 to ensure the stability of the sound insulation board 21 installed on the side of the air heat energy pump housing 1. The rubber on the outer side of the insertion shaft end of the fixed insertion rod 27 The rubber ring end design allows the rubber ring end to contact the inner wall of the through hole of the fixing seat 26 and the limit block 25 when the fixed plug rod 27 is inserted, so as to prevent the limit block 25 from shaking and colliding to generate noise. The connecting tube 31 is wrapped by the inner lining tube 323, which can effectively reduce the vibration noise generated by the connecting tube 31 driven by the liquid flow. When noise is generated, the right guide ring plate 324 and the left cutting ring plate 325 on the inner wall of the inner lining tube 323 can refract the sound waves, and then repeatedly refract and reduce the sound waves generated by the liquid flow, thereby ensuring the sound-absorbing and noise-reducing effect of the external sleeve 321.

[0033] The sound waves reflected by the right guide ring plate 324 and the left cutting ring plate 325 can be transmitted and guided through the pores of the inner lining tube 323, so that the sound waves can be absorbed by the annular sound-absorbing cotton 326 between the external sleeve 321 and the inner lining tube 323 during movement, thereby improving the noise reduction effect on the connecting pipe 31. A threaded ring 322 is connected to the left side of the external sleeve 321, and an external thread is arranged on the right side of the external sleeve 321. Multiple external sleeves 321 can be butted end to end with threaded joints, so that multiple external sleeves 321 can be matched with the appropriate length of the connecting pipe 31. The vibration sensor 52 can capture the tiny vibration of the pipeline. The vibration sensor 52 is installed at the place where the noise is strongest on the right side of the circulation pump 4 to maximize energy collection. The vibration sensor 52 can convert the vibration of the pipeline into its own mechanical vibration. When the pressure pad ceramic ring 51 senses mechanical stress, it will generate charges when subjected to mechanical stress. These charges can be converted into electrical energy through the circuit. The charges generated by the pressure pad ceramic ring 51 are transmitted to the energy storage device through the wire, and the rectifier 53 is used to convert the alternating current into direct current, and a voltage stabilizer is used to maintain the stability of the output voltage. The electrical energy converted from the vibration noise of the connecting pipe 31 is used to ensure the normal operation of the pipeline detection instrument 54.

[0034] Working principle: According to the attached Figure 1 With attached Figure 2 As shown, during use, when the electrical components inside the air heat pump housing 1 are deployed, the sound insulation board 21 is pulled, and the sound insulation board 21 can drive the rubber plate 23 to contact the surface of the air heat pump housing 1 during rotation. At this time, the limit block 25 can be inserted into the groove of the fixing seat 26 along with the movement of the sound insulation board 21, and the fixed plug rod 27 is inserted into the top of the fixing seat 26, so that the axis of the fixed plug rod 27 passes through the through hole of the fixing seat 26 and the limit block 25, ensuring that the sound insulation board 21 is stably installed on the outside of the air heat pump housing 1; Secondly, according to the attached Figure 6 With attached Figure 7As shown, the threaded end of the external sleeve 321 is connected to the threaded collar 322 on the side of another external sleeve 321, and multiple external sleeves 321 are connected in sequence. At this time, the inner liner tube 323 can be sleeved on the surface of the connecting tube 31. When the liquid moves in the connecting tube 31, the vibration noise generated by the movement of the liquid is repeatedly refracted by the right guide ring plate 324 and the left cut ring plate 325, thereby reducing the sound waves. At this time, the cavity between the inner liner tube 323 and the external sleeve 321 is embedded with an annular sound-absorbing cotton 326, and the noise sound waves can be refracted through the pores of the annular sound-absorbing cotton 326, so that the annular sound-absorbing cotton 323 can be used to reduce the sound waves. 26 absorbs sound waves, thereby achieving a noise reduction effect. When the liquid passes through the circulation pump 4, the right pipe of the circulation pump 4 vibrates in the flow of liquid. The pressure pad ceramic ring 51 generates charges when it is subjected to the mechanical stress converted by the vibration sensor 52. These charges can be converted into electrical energy through the circuit. The charges generated by the pressure pad ceramic ring 51 are transmitted to an energy storage device such as a battery or a capacitor through a wire. At this time, a rectifier 53 is used to convert alternating current into direct current, and a voltage stabilizer is used to maintain the stability of the output voltage. The status of the right pipe of the circulation pump 4 can be monitored through the pipeline detection instrument 54.
