Description

Technical Field

[0001] The utility model relates to the technical field, and specifically provides a noise reduction structure for a cold storage air compressor. Background Art

[0002] An air compressor is a device used to compress gases. The air compressor is similar in structure to a water pump. Most air compressors are reciprocating pistons, rotary vanes or rotary screws. In a cold storage, the air compressor compresses low-temperature refrigerant to absorb and discharge the heat in the air, so as to achieve the effects of freshness preservation, cooling, temperature reduction, etc. However, the air compressor generates a relatively large noise during operation, which will affect the surrounding environment. Therefore, noise reduction treatment is required.

[0003] A noise reduction device for a cold storage compressor is disclosed in the related technology (publication number: CN217354647U). The disclosed technical solution is as follows: The first spring connected to the bottom of the cold storage compressor buffers it to prevent the cold storage compressor from directly vibrating the ground to generate noise and spread. Then, the noise reduction holes opened inside the noise reduction box absorb the sound transmitted through the air, and most of the energy of the noise sound wave is absorbed inside the noise reduction holes. The residual sound wave energy inside the noise reduction holes is absorbed by the sound-absorbing cotton to achieve the purpose of noise reduction during the operation of the cold storage compressor. At the same time, the first motor drives the reciprocating screw rod to rotate, and then the first gear on the surface of the rotating shaft inside the moving plate meshes with the rack to rotate. The rotation of the rotating shaft drives the fan blade at the top to rotate, accelerating the air circulation inside the noise reduction box, and dissipating the heat emitted by the cold storage compressor through the ventilation holes, preventing the noise reduction box from being installed outside the cold storage compressor and reducing the heat dissipation effect of the cold storage compressor.

[0004] In the above-mentioned disclosed technical solution, it is found that the following problems exist in the related technology: After opening a plurality of noise reduction holes on the circumferential outer wall of the noise reduction box, it makes the air circulate with the outside, resulting in more gaps for the sound to be transmitted to the outside, thus reducing the noise reduction effect. When the compressor is placed outdoors and there is too much accumulated water in the placement area, it will affect the compressor. For this reason, we propose a new noise reduction structure for a cold storage air compressor.

[0005] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background art section of the present application. Therefore, it may include prior art information that does not constitute known information to those of ordinary skill in the art. Summary of the Utility Model

[0006] The utility model aims to solve at least one of the technical problems existing in the prior art or related technologies. To solve the problem of air compressor noise reduction in the above-mentioned prior art, the utility model provides a noise reduction structure for a cold storage air compressor, which combines a noise reduction component with an induction waterproof component to achieve the effects of protection and noise reduction. The specific technical solution is as follows:

[0010] The driving component includes a first gear rotatably arranged on the outer wall of the noise reduction groove, a through groove corresponding to the first gear is arranged on the outer wall of the noise reduction groove, a second gear is sleeved on the outer wall of the sleeve, and the first gear passes through the through groove and meshes with the second gear.

[0011] An anti-deviation component for guiding the groove cover is arranged at the remaining inner wall corners of the noise reduction groove.

[0012] The anti-deviation component includes a sleeve rod fixedly installed at the bottom of the inner wall of the noise reduction groove, a stabilizing rod is fixedly installed on the inner wall of the groove cover, and the sleeve rod is sleeved outside the stabilizing rod.

[0013] The shock absorption component includes a fixed seat fixedly installed at the bottom of the inner wall of the noise reduction groove, a movable rod is inserted into the inner cavity of the fixed seat, a connecting seat for connecting the bottom of the air compressor is fixedly installed at the top end of the movable rod, an elastic member is arranged between the connecting seat and the fixed seat, and the elastic member is sleeved outside the movable rod.

[0017] Compared with the prior art, the beneficial effects of the present utility model are: the noise reduction structure of this cold storage air compressor:

[0018] 1. Fix the bottom of the air compressor on the shock-absorbing components. The shaking force during the operation of the air compressor is reduced by four shock-absorbing components located at the bottom of the inner wall of the noise reduction groove. The acting force during the shaking process of the air compressor is offset by the buffering effect of the shock-absorbing components, thereby reducing the noise.

[0020] 3. When the water level is close to the bottom of the noise reduction groove, the water level monitor transmits a signal to the lifting component, causing the movable end of the hydraulic cylinder to exert a force on the support seat. The reaction force generated at the cylinder barrel end of the hydraulic cylinder drives the noise reduction groove to move away from the placement surface, thereby increasing the distance between the bottom of the noise reduction groove and the placement surface, avoiding the influence of accumulated water on the noise reduction groove, and further protecting the air compressor.

[0021] 4. When overhauling or taking the air compressor, the sleeve is rotated through the driving component, and the lead screw threadedly connected to the sleeve drives the groove cover to move in the vertical direction, thereby opening or closing the groove cover, making the operation process more convenient, and further bringing convenience to the operation process of relevant personnel.

[0022] 5. During the process of rotating the sleeve to adjust the position of the groove cover, the groove cover drives the stabilizing rod to slide along the inner wall of the sleeve rod. The stabilizing rod parallel to the lead screw ensures the stability of the moving direction of the groove cover, avoiding position deviation, and thus ensuring the sealing performance after the noise reduction groove is closed.

[0023] 6. The air blower achieves the effect of air circulation, thereby ensuring that the heat generated during the operation of the air compressor can be discharged to the outside.

[0024] 7. Grooves are evenly opened on the inner wall of the noise reduction groove, and the sound insulation cotton is fixedly embedded inside the grooves. The set sound insulation cotton enhances the sound insulation effect. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0033] Next, in combination with specific implementation cases and attached Figures 1-6 the present utility model will be further described, but the present utility model is not limited to these embodiments.

[0034] A noise reduction structure of a cold storage air compressor includes a noise reduction groove 1, and a groove cover 2 is arranged on the top of the noise reduction groove 1. The groove cover 2 corresponds to the shape of the noise reduction groove 1, so that after the groove cover 2 fits on the top of the noise reduction groove 1, the noise reduction groove 1 is in a sealed space. An adjusting component for opening and closing the groove cover 2 is arranged at the adjacent wall of the inner cavity of the noise reduction groove 1. The position of the groove cover 2 is adjusted through the adjusting component, and the noise reduction groove 1 is opened and closed by adjusting the groove cover 2 up and down. After the noise reduction groove 1 is opened, the air compressor is placed inside the noise reduction groove 1, and then the groove cover 2 is closed, so that the air compressor is placed inside the noise reduction groove 1.

[0035] At the bottom of the inner wall of the noise reduction groove 1, a shock absorption component for buffering the operation of the air compressor is provided. The bottom of the air compressor is fixed on the shock absorption component. The shaking force during the operation of the air compressor is reduced by four shock absorption components located at the bottom of the inner wall of the noise reduction groove 1. The acting force during the shaking process of the air compressor is offset by the buffering effect of the shock absorption component, thereby reducing the noise. Ventilation holes 5 are evenly formed at the bottom of the noise reduction groove 1. Through the multiple ventilation holes 5 formed on the bottom of the noise reduction groove 1 and communicating with the inner cavity, the heat generated during the operation of the air compressor is discharged, thereby protecting the air compressor.

[0036] At the bottom of the noise reduction groove 1, a lifting component for adjusting the distance from the placement surface is provided, and a water level monitor 6 electrically connected to the lifting component is arranged at the bottom of the noise reduction groove 1. The water level monitor 6 located at the bottom of the noise reduction groove 1 monitors the water accumulation inside the noise reduction groove 1. When the water level is approaching the bottom of the noise reduction groove 1, the water level monitor 6 transmits a signal to the lifting component. The position of the air compressor inside the noise reduction groove 1 is adjusted through the lifting component, avoiding damage to the air compressor caused by the accumulated water on the placement surface, thereby playing a protective effect on the air compressor.

[0037] Among them, the component includes a support base 12 arranged at the bottom of the noise reduction groove 1, and a hydraulic cylinder 10 is arranged between the support base 12 and the noise reduction groove 1. The hydraulic cylinder 10 is electrically connected to the water level monitor 6. The water level monitor 6 is a monitor of model JD-JS1 produced by Jingdao Company for monitoring water accumulation on urban roads. The water level monitor 6 is electrically connected to the hydraulic cylinder 10 through a wire.

[0038] First, set the water level monitor 6 to the corresponding water level induction point. When the water accumulation height reaches the induction point of the water level monitor 6, the water level monitor 6 transmits a signal to the controller. The controller drives the hydraulic cylinder 10, so that the movable end of the hydraulic cylinder 10 exerts a force on the support base 12. The reaction force generated at the cylinder end of the hydraulic cylinder 10 drives the noise reduction groove 1 to move away from the placement surface, so that the distance between the bottom of the noise reduction groove 1 and the placement surface is increased, avoiding the influence of the accumulated water on the noise reduction groove 1, and further playing a protective effect on the air compressor.

[0039] It should be noted that the adjusting component includes a sleeve 7 rotatably arranged at the inner wall corners of the noise reduction groove 1. A lead screw 8 is threadedly connected to the inner cavity of the sleeve 7, and the top end of the lead screw 8 is fixedly installed on the inner wall of the groove cover 2. A driving component for driving the sleeve 7 to rotate is arranged on the outer wall of the noise reduction groove 1. Two bases 18 are fixedly installed symmetrically up and down at the inner wall corners of the noise reduction groove 1. Through holes penetrating the inner cavity are longitudinally formed on the surfaces of the two bases 18. Two bearings are respectively embedded in the inner walls of the through holes inside the two bases 18. The hollow-structured sleeve 7 is simultaneously embedded in the interiors of the two bearings, and both ends of the sleeve 7 extend out of both sides of the base 18.

[0040] A threaded through-hole penetrating the inner cavity is longitudinally opened on the surface of the sleeve 7, and the lead screw 8 is threadedly connected to the sleeve 7 through the external thread on its outer wall. The upper end of the lead screw 8 is fixed to the inner wall of the groove cover 2. When the air compressor is overhauled or taken, the sleeve 7 is rotated through the driving assembly, so that the lead screw 8 threadedly connected to the sleeve 7 drives the groove cover 2 to move in the vertical direction. Thus, the groove cover 2 is opened or closed, making the operation process more convenient, and further bringing convenience to the operation process of relevant personnel.

[0041] In addition, the driving assembly includes a first gear 22 rotatably arranged on the outer wall of the noise reduction groove 1, and a through groove 20 corresponding to the first gear 22 is opened on the outer wall of the noise reduction groove 1. A second gear 19 is sleeved on the outer wall of the sleeve 7, and the first gear 22 passes through the through groove 22 and meshes with the second gear 19. The second gear 19 is fixedly sleeved on the outside of the sleeve 7 through the mounting hole opened at the center, and the second gear 19 is located between the two bases 18. A through groove 20 penetrating the side wall of the noise reduction groove 1 is opened at the position corresponding to the second gear 19.

[0042] On the outer wall of the noise reduction groove 1 corresponding to the through groove 20, the motor 23 is fixed through a motor base, and the housing 11 covers the outside of the motor 23 and is fixed on the outer wall of the noise reduction groove 1 to protect the motor 23 through the housing 11. The first gear 22 is fixedly sleeved on the outside of the output shaft of the motor 23 through the mounting hole at the center, and the first gear 22 passes through the through groove 20 and then meshes with the second gear 19.

[0043] When adjusting the position of the groove cover 2, the motor 23 is connected to the power supply, so that the output shaft of the motor 23 drives the first gear 22 to rotate, and the second gear 19 meshing with the first gear 22 drives the sleeve 7 to rotate. The threadedly connected lead screw 8 drives the groove cover 2 to move, so as to open and close the noise reduction groove 1, making the operation process more convenient.

[0044] In addition, anti-deviation components for guiding the groove cover 2 are provided at the other inner wall corners of the noise reduction groove 1.

[0045] Furthermore, the anti-deviation component includes a sleeve rod 16 fixedly installed at the bottom of the inner wall of the noise reduction groove 1, and a stabilizing rod 17 is fixedly installed on the inner wall of the groove cover 2, and the sleeve rod 16 is sleeved on the outside of the stabilizing rod 17. A groove hole with a certain depth is opened at the top end of the sleeve rod 16, and the aperture of the groove hole corresponds to the stabilizing rod 17, so that the stabilizing rod 17 and the sleeve rod 16 form a telescopic rod structure.

[0046] During the process of rotating the sleeve 7 to adjust the position of the groove cover 2, the groove cover 2 drives the stabilizing rod 17 to slide along the inner wall of the sleeve rod 16. The stabilizing rod 17 parallel to the lead screw 8 ensures the stability of the moving direction of the groove cover 2, avoids position deviation, and thus ensures the sealing performance after the noise reduction groove 1 is closed.

[0047] The shock absorption assembly includes a fixed seat 14 fixedly installed at the bottom of the inner wall of the noise reduction groove 1. A movable rod 15 is inserted into the inner cavity of the fixed seat 14. A connecting seat 13 for connecting the bottom of the air compressor is fixedly installed at the top of the movable rod 15. An elastic member 9 is arranged between the connecting seat 13 and the fixed seat 14, and the elastic member 9 is sleeved outside the movable rod 15. The connecting seat 13 is fixed to the bottom of the air compressor through an installation hole opened on the surface and penetrating the inner cavity, so that the air compressor is fixed on the tops of four connecting seats 13 at the same time. The elastic member 9 can be a compression spring. The two ends of the elastic member 9 are respectively fixed to the bottom of the connecting seat 13 and the top of the fixed seat 14. The elastic member 9 is movably sleeved outside the movable rod 15, so that the elastic member 9 fits on the outer wall of the movable rod 15 and slides telescopically.

[0048] After the air compressor is fixed on the tops of four connecting seats 13, the elastic deformation of the elastic member 9 plays a buffering effect, thereby achieving a noise reduction effect.

[0049] A blower 4 is embedded at the top of the groove cover 2. The blower 4 is electrically connected to an external power source through a wire. The blower 4 is fixedly embedded and installed at the top of the groove cover 2. The blower 4 achieves an air circulation effect, thereby ensuring that the heat generated when the air compressor works can be discharged to the outside.

[0050] Above the blower 4, there is a protective top 24 fixed to the top of the groove cover 2. The protective top 24 is conical. The lower ends of four legs 25 are vertically fixed to the top of the groove cover 2, and the upper ends of the four legs 25 are fixed to the inner wall of the protective top 24. The protective top 24 located above the blower 4 plays a protective effect on the blower 4.

[0051] Sound insulation cotton 3 is evenly embedded in the inner wall of the noise reduction groove 1, and grooves are evenly opened on the inner wall of the noise reduction groove 1. The sound insulation cotton 3 is fixedly embedded inside the grooves, and the set sound insulation cotton enhances the sound insulation effect.
