Description

Technical Field

[0001] This utility model relates to the field of air outlet silencing technology, and in particular to an air source heat pump noise reduction air outlet silencing device. Background Technology

[0002] The internal compressor of an air source heat pump generates considerable noise during high-speed operation, and this noise is transmitted to the air outlet through the pipes. In order to reduce the noise interference with people's rest, work and life, a resistive plate silencer is installed at the air outlet of the air source heat pump to achieve the purpose of noise reduction.

[0003] Currently, existing resistive silencers mainly consist of a frame and multiple sets of sound-absorbing panels. After a period of use, in order to ensure the noise reduction effect at the air outlet, workers will remove the dust-accumulated and aged sound-absorbing panels from the frame. However, since the sound-absorbing panels are connected to the frame with screws, the disassembly and assembly process requires the use of auxiliary tools to laboriously turn the screws, which affects the efficiency of the workers in disassembling the sound-absorbing panels. To address this issue, we propose an air source heat pump noise reduction air outlet silencer device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an air source heat pump noise reduction outlet silencing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An air source heat pump noise reduction vent silencing device includes an air source heat pump body. Symmetrical air outlets are formed on the upper part of the air source heat pump body, and a frame is fitted around the outer side of the air outlets. The bottom of the frame is fixedly connected to the upper side of the air source heat pump body. Supporting strips are symmetrically connected to the inner wall of the frame, and a sound-absorbing plate is placed above the supporting strips. A connecting strip is fixedly connected to the top of the sound-absorbing plate. A fixing block is connected to the inner wall of the upper side of the frame, and an insertion slot is formed inside the fixing block. An insertion plate is inserted into the insertion slot, and a connecting spring is connected to the end of the insertion plate. The other end of the connecting spring is connected to the end of the insertion slot. A limiting plate is connected to the side of the insertion plate away from the connecting spring. An insertion groove adapted to the limiting plate is formed on the side of the connecting strip.

[0007] Preferably, a handle is connected above the limiting plate, and the outer wall of the handle is evenly distributed with anti-slip particles.

[0008] Preferably, there are two sets of fixing blocks and insertion slots, and the two sets of fixing blocks and insertion slots are symmetrically distributed about the central axis of the frame.

[0009] Preferably, the two sets of fixing blocks are connected by a mounting plate, and the interior of the mounting plate is connected to the top wall of the frame by bolts.

[0010] Preferably, positioning posts are equidistantly connected above the support strip, and a limiting groove adapted to the positioning posts is provided at the bottom of the sound-absorbing plate.

[0011] Preferably, a slider is connected to the side of the insertion plate away from the limiting plate, and a groove adapted to the slider is opened inside the fixing block.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This device is equipped with a fixing block and a limiting plate. During use, the fixing block and the limiting plate work together to allow the staff to quickly pull out the corresponding sound-absorbing panels from inside the frame for replacement and maintenance. This eliminates the need for staff to use auxiliary tools for time-consuming and laborious disassembly, thus effectively improving the overall maintenance efficiency of the staff.

[0014] 2. The device is equipped with support bars and positioning columns.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A noise reduction and silencing device for an air source heat pump outlet includes an air source heat pump body 1. Symmetrical air outlets 2 are formed on the upper part of the air source heat pump body 1. A frame 3 is fitted around the outer side of the air outlets 2. The bottom of the frame 3 is fixedly connected to the upper side of the air source heat pump body 1. The connection method between the top of the air source heat pump body 1 and the frame 3 is existing technology and will not be described in detail here. Supporting strips 4 are symmetrically connected to the inner wall of the frame 3, and a sound-absorbing panel 5 is placed on top of the supporting strips 4. The supporting strips 4 support the sound-absorbing panel 5. The supporting strips 4 are located above the air outlets 2, ensuring normal airflow from the air outlets 2 and allowing the sound-absorbing panel 5 to be smoothly inserted into the frame 3. The top of the sound-absorbing panel 5... A connecting strip 6 is fixedly connected, and a fixing block 7 is connected to the inner wall of the upper side of the frame 3. The fixing block 7 has an insertion slot 8 inside, and an insertion plate 10 is inserted into the insertion slot 8. A connecting spring 9 is connected to the end of the insertion plate 10, and the other end of the connecting spring 9 is connected to the end of the insertion slot 8. A limiting plate 11 is connected to the side of the insertion plate 10 away from the connecting spring 9. During use, the limiting plate 11 can be moved laterally by the cooperation of the insertion plate 10 and the connecting spring 9, so that the limiting plate 11 can be inserted into the insertion slot opened on the side of the connecting strip 6, or pulled out from the inside of the insertion slot, so as to achieve quick disassembly of the connecting strip 6. The side of the connecting strip 6 has an insertion slot that matches the limiting plate 11.

[0022] Furthermore, refer to Figure 3 and Figure 4 It can be seen that a handle 12 is connected above the limiting plate 11, and anti-slip particles are evenly distributed on the outer wall of the handle 12. During use, the handle 12 and the anti-slip particles work together to facilitate the staff to quickly pull the handle 12 horizontally, thereby effectively improving the convenience of using the device.

[0023] Furthermore, refer to Figure 1 and Figure 3 It can be seen that there are two sets of fixing blocks 7 and insertion slots 8, and the two sets of fixing blocks 7 and insertion slots 8 are symmetrically distributed about the central axis of frame 3. During use, the stability of handle 12 when it moves laterally can be effectively guaranteed by the cooperation of the two sets of insertion slots 8 and fixing blocks 7.

[0024] Furthermore, refer to Figure 3It can be seen that the two sets of fixing blocks 7 are connected by mounting plate 15, and the interior of mounting plate 15 is connected to the top wall of frame 3 by bolts. The top of frame 3 is provided with screw holes that are compatible with the bolts. Through the cooperation of mounting plate 15 and bolts, the connection operation between mounting plate 15 and the top of frame 3 can be realized, which makes it easy for workers to remove and replace the fixing blocks 7 that have reached the end of their service life.

[0025] Furthermore, refer to Figure 3 and Figure 4 It can be seen that positioning posts 14 are equidistantly connected above the support bar 4, and the bottom of the sound-absorbing plate 5 is provided with a limiting groove that matches the positioning posts 14. In use, the sound-absorbing plate 5 and the connecting bar 6 inserted inside the frame 3 can be laterally limited by the positioning posts 14 and the limiting groove at the bottom of the sound-absorbing plate 5.

[0026] Furthermore, refer to Figure 4 It can be seen that the side of the insertion plate 10 away from the limiting plate 11 is connected to the slider 13. The inside of the fixing block 7 is provided with a sliding groove that matches the slider 13. When the operator pulls the handle 12, the limiting plate 11 connected to its bottom can be subjected to force at the same time, so that the insertion plate 10 connected to the side of the limiting plate 11 is subjected to force at the same time and slides along the inner wall of the insertion groove 8. During the sliding process of the insertion plate 10, the slider 13 connected to its side can be subjected to force and slide along the inner wall of the sliding groove, thereby realizing the lateral guidance of the limiting plate 11 to ensure the stable lateral movement of the limiting plate 11.

[0027] Working Principle: During operation of the air source heat pump body 1, the noise generated is transmitted through the air outlet 2. This noise is absorbed by the frame 3 at the top of the air source heat pump body 1 and the various sound-absorbing panels 5 inserted inside the frame 3, thus achieving noise reduction and sound attenuation. After a period of use, when the sound-absorbing panels 5 need to be disassembled for maintenance, the handle 12 is manually pulled to move the limiting plate 11 connected to its bottom laterally, thereby removing the limiting plate 11 from its connection point. The connecting strip 6 is pulled out of the insertion slot on the side to release the restriction on each set of connecting strips 6. Then, the worker can pull up the corresponding connecting strip 6 to drive the sound-absorbing plate 5 connected to its lower side to be stressed at the same time, so as to pull out the limiting slot at the bottom of the sound-absorbing plate 5 from the outer wall of the positioning post 14, thus realizing the quick disassembly of the sound-absorbing plate 5. After disassembly, the worker can stop pulling the handle 12, so that the handle 12 is reset by the elastic force of the connecting spring 9, so that the handle 12 is inserted back into the insertion slot on the side of the connecting strip 6. The above is the entire working principle of this utility model.

As long as they can achieve their beneficial effects, they can be implemented, so they will not be described in detail.
