Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0006] Given the following technical problems in the existing technology: when an air compressor is placed and used in an air compressor room, the air compressor will vibrate during operation, and the collision between the air compressor and the air compressor room will cause noise from the air compressor room, affecting the surrounding environment.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a noise reduction device for an air compressor room, comprising a housing, an upper baffle, and pipes;

[0008] The upper hinge is positioned above the housing box, and the pipe is connected to the side of the housing box.

[0009] The chamber is equipped with a pair of support platforms, which are mirror images of each other about the center line of the chamber. A number of degradation units are arranged along the inner edge of the chamber.

[0010] The degradation unit includes a movable ring, a positioning frame, a flexible arm, and a central rod. The movable ring is hinged to the inner edge of the chamber, the positioning frame is fixed to the inner edge of the chamber, the positioning frame is located outside the movable ring, the movable ring is located in the center of the positioning frame, and the flexible arm is disposed on the circular surface of the movable ring.

[0011] The lower inner edge of the housing has a conveying cylinder that telescopically moves, the upper inner edge of the conveying cylinder has a damping pad one that telescopically moves, and the lower inner edge of the conveying cylinder has a damping pad two that telescopically moves.

[0012] As a preferred technical solution for noise reduction equipment in an air compressor room, the central rod is fixed to the inner edge of the chamber, and the central rod is located in the middle of the movable ring and is hinged to it. The inner edge of the positioning frame is defined as the inner edge surface. The inner edge of the flexible arm faces the movable ring, the outer edge of the flexible arm faces the inner edge surface, and the part of the flexible arm facing the positioning frame is guided to dock with the inner edge surface.

[0013] As a preferred technical solution for noise reduction equipment in air compressor rooms, the circular surface of the movable ring has a number of positioning grooves, which are arranged in an array. The number of positioning grooves is the same as the number of flexible arms. Positioning blocks are installed on the flexible arms facing the movable ring, and the positioning blocks are fitted into the positioning grooves. A baffle is provided on the front surface of the movable ring.

[0014] As a preferred technical solution for noise reduction equipment in air compressor rooms, the front of the baffle is equipped with a movable frame, the edge of the movable frame is connected to a bearing arm, and the bearing arm is equipped with a linkage column facing the positioning frame.

[0015] As a preferred technical solution for noise reduction equipment in air compressor rooms, the flexible arm is hinged to a guide roller at the part facing the positioning frame, and the guide roller is guided to engage with the surface of the inner edge.

[0016] As a preferred technical solution for noise reduction equipment in air compressor rooms, the inner edge of the positioning frame is milled with a groove, and the flexible arm facing the positioning frame is milled with a U-shaped groove. The flexible arm is connected to the edge of the groove by the U-shaped groove.

[0017] As a preferred technical solution for noise reduction equipment in an air compressor room, the linkage column is hinged with a linkage bar at the part facing the support platform, and a long groove is reserved at the edge of the support platform facing the degradation unit, with the linkage bar disposed in the long groove.

[0018] As a preferred technical solution for noise reduction equipment in air compressor rooms, a protrusion is installed on the upper surface of the inner edge of the support platform.

[0019] As a preferred technical solution for noise reduction equipment in air compressor rooms, a flexible rod is configured between the first damping pad and the second damping pad.

[0020] As a preferred technical solution for noise reduction equipment in air compressor rooms, a linkage rod is configured between the damping pad and the lower part of the support platform, and an elastic element is wrapped around a section of the linkage rod in the conveying cylinder.

[0021] The beneficial effects of this invention are:

[0022] 1. This air compressor room noise reduction equipment relies on a pair of support platforms to support the air compressor. When the air compressor is running, it will vibrate. The degradation unit can alleviate the movement of the support platforms, reduce the collision between the support platforms and the room, and achieve the effect of noise reduction.

[0023] 2. When the vibration amplitude is large, the noise reduction equipment for this air compressor room can ensure that the flexible arm acts stably on the positioning frame through the cooperation of the guide roller, U-shaped groove and concave groove. When the edge of the flexible arm is in contact with the concave groove, it can provide a bearing part, which can improve the vibration reduction effect and protect the flexible arm. In this way, it can achieve a high-intensity anti-vibration and noise reduction effect during the operation of the air compressor.

[0024] 3. The noise reduction equipment in this air compressor room relies on the linkage bar to bring a pair of support platforms close to each other under the action of downward force. At this time, it can limit the air compressor and ensure the stability of the air compressor when it is placed and moved.

[0025] 4. When the air compressor room noise reduction equipment relies on the bearing platform to vibrate during the operation of the air compressor, the bearing platform will squeeze the damping pad one. The damping pad one will change position by means of the flexible rod and the linkage with the damping pad two. The damping pad two can blow the gas in the conveying cylinder out. Under the action of the through holes and protrusions on the chamber, the heat energy generated by the air compressor during operation can be replaced and removed. In this way, the noise reduction of the air compressor during operation can be achieved at the same time as the temperature control inside the chamber.

[0043] An embodiment of a noise reduction device for an air compressor room includes a housing 10, an upper baffle 11, and a pipe 12.

[0044] Reference Figure 1 The upper baffle 11 is hinged and positioned above the chamber 10, and the pipe 12 is connected to the edge of the chamber 10.

[0045] Reference Figure 2 The chamber 10 is equipped with a pair of support platforms 30, which are mirror images of each other about the center line of the chamber 10. A number of degradation units 40 are arranged along the inner edge of the chamber 10.

[0046] Reference Figure 3 , 5 6, 7, and 8, the degradation unit 40 includes a movable ring 41, a positioning frame 44, a flexible arm 47, and a central rod 414. The movable ring 41 is hinged to the inner edge of the chamber 10. The positioning frame 44 is fixed to the inner edge of the chamber 10 and is located outside the movable ring 41. The movable ring 41 is located in the center of the positioning frame 44. The central rod 414 is fixed to the inner edge of the chamber 10 and is located in the middle of the movable ring 41 and is hinged to it. The inner edge of the positioning frame 44 is defined as the inner edge surface 45. The flexible arm 47 is disposed on the circular surface of the movable ring 41. The inner edge of the flexible arm 47 faces the movable ring 41, and the outer edge of the flexible arm 47 faces... The flexible arm 47 is guided to dock with the positioning frame 44 on the inner edge surface 45. The circular surface of the movable ring 41 has a number of positioning grooves 42. The positioning grooves 42 are arranged in an array. The number of positioning grooves 42 is the same as the number of flexible arms 47. The part of the flexible arm 47 facing the movable ring 41 is equipped with a positioning block 48. The positioning block 48 is fitted and docked with the positioning groove 42. The front surface of the movable ring 41 is equipped with a baffle 43. The front of the baffle 43 is equipped with a movable frame 49. The edge of the movable frame 49 is docked with a bearing arm 410. The part of the bearing arm 410 facing the positioning frame 44 is equipped with a linkage column 411.

[0047] The above content can achieve the following: when the linkage column 411 is linked to change position, under the action of the movable frame 49, the movable ring 41 can rotate, the flexible arm 47 is guided at the position change part of the positioning frame 44, the flexible arm 47 bends, and the flexible arm 47 has a damping effect under its own characteristics.

[0048] The linkage column 411 provides support for the bearing platform 30. When the air compressor is running, it will vibrate, and the air compressor will move the position of the linkage bearing platform 30.

[0049] There are three inner edge surfaces 45. The middle positions of the three inner edge surfaces 45 are recorded as X, Y, and Z coordinates. When the flexible arm 47 is rotating, the contact point between the flexible arm 47 and the positioning frame 44 changes position towards the X, Y, and Z coordinates. At this time, the flexible arm 47 can bend under load.

[0050] When the air compressor is running: the air compressor will vibrate, and the support platform 30 will move towards the lower part of the chamber 10 at this time, and the degradation unit 40 will support the support platform 30.

[0051] When the support platform 30 changes position downwards, it will move in conjunction with the linkage column 411. At this time, the support arm 410 and the movable frame 49 will rotate. The movable ring 41 will move in conjunction with the flexible arm 47 to change position along the inner edge of the positioning frame 44. The flexible arm 47 will bend during this process.

[0052] The bearing platform 30 reciprocates, and the vibration generated by the flexible arm 47 during this process is dissipated, thereby dissipating the vibration generated by the air compressor.

[0053] Reference Figure 7 The flexible arm 47 is hinged to the positioning frame 44 with a guide roller 412, which guides and docks with the surface of the inner edge 45. At this time, the flexible arm 47 can act precisely on the inner edge 45, ensuring the bending effect of the flexible arm 47. Under the action of the guide roller 412, the flexible arm 47 will not be rigidly squeezed with the positioning frame 44, thus improving the working cycle of the flexible arm 47.

[0054] Reference Figure 7 The inner edge of the positioning frame 44 is milled with a groove 46, and the flexible arm 47 facing the positioning frame 44 is milled with a U-shaped groove. The flexible arm 47 is connected to the edge of the groove 46 by the U-shaped groove. During the rotation process, the flexible arm 47 moves completely along the inner edge surface 45 by relying on the cooperation of the U-shaped groove and the groove 46. When the vibration amplitude is large, the U-shaped groove of the flexible arm 47 will be squeezed against the edge of the groove 46.

[0055] The above achieves the following: When the movable ring 41 rotates, the guide roller 412 of the flexible arm 47 will change position along the inner edge surface 45, and the middle section of the flexible arm 47 will bend to varying degrees depending on the load. A number of flexible arms 47 can decompose the vibration force, so that the vibration of the air compressor during operation will not collide with the housing 10 or the effect of contact will be mitigated, thereby reducing the noise generated between the air compressor and the housing 10 during operation. When the vibration amplitude of the air compressor is large during operation, the U-shaped groove of the flexible arm 47 will press against the edge of the groove 46. At this time, the bending of the flexible arm 47 can be blocked to a certain extent. When the flexible arm 47 touches the inner edge of the groove 46, an additional bearing point can be added to improve the effect of the flexible arm 47 in degrading the vibration force, which can further degrade the vibration force and improve the noise reduction effect.

[0056] Reference Figure 8 and 9 A linkage bar 413 is hinged to the part of the linkage column 411 facing the support platform 30. A long groove 31 is reserved at the edge of the support platform 30 facing the degradation unit 40, and the linkage bar 413 is arranged in the long groove 31.

[0057] The above can achieve the following: when the air compressor shakes or is placed, the support platform 30 will change its position downwards, and the pair of support platforms 30 will move closer together. At this time, the air compressor can be limited by the support platform 30, thereby ensuring the stability of the air compressor after placement.

[0058] Reference Figure 4 and 8 The inner edge of the support platform 30 is provided with a protrusion 32. Under the action of the protrusion 32, firstly, it can effectively avoid the noise caused by contact with the support platform 30; secondly, it can protect the air compressor when it is placed; and thirdly, it can ensure that the heat generated by the air compressor during operation can be discharged.

[0059] Reference Figure 10 The lower part of the housing 10 has a conveyor cylinder 20 that can telescopically move along its inner edge. The conveyor cylinder 20 can move in a way that perfectly matches the movement characteristics of the support platform 30. The upper part of the conveyor cylinder 20 has a damping pad 21 that telescopically moves inside, and the lower part of the conveyor cylinder 20 has a damping pad 22 that telescopically moves inside. A flexible rod 23 is arranged between the damping pad 21 and the damping pad 22. A linkage rod 24 is arranged between the damping pad 21 and the lower part of the support platform 30. An elastic element 25 surrounds a section of the linkage rod 24 in the conveyor cylinder 20.

[0060] The above can achieve the following: when the support platform 30 moves towards the lower part of the chamber 10, the support platform 30 will squeeze the damping pad 21. The damping pad 21 changes position by means of the flexible rod 23 and the damping pad 22. The damping pad 22 can blow out the gas in the conveying cylinder 20. Under the action of the through hole on the chamber 10, the heat energy generated by the air compressor in the chamber 10 can be replaced. At the same time, the elastic element 25 can provide a damping effect for the support platform 30.

[0061] It should be understood that numerous specific implementation decisions can be made during the development of any actual implementation method, and in any engineering or design project. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0062] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
