Description

Technical Field

[0001] This utility model relates to the field of air conditioner bracket technology, and in particular to a shipborne air conditioner vibration damping and noise reduction bracket device. Background Technology

[0002] Marine air conditioning brackets are an indispensable and important component of marine air conditioning systems. In the special operating environment of a ship, they play a crucial role in supporting and fixing the outdoor air conditioning unit, ensuring that the outdoor unit remains stable under various operating conditions on the ship.

[0003] Marine air conditioner brackets are often made of high-strength, high-load-bearing metal materials such as angle steel and I-beams, and are assembled by bolts or welding. This allows the marine air conditioner bracket to provide effective fixation for the outdoor unit of the air conditioner. Even if the ship encounters wind and waves during navigation and the outdoor unit is rocked, it can always maintain a stable state and ensure the normal operation of the air conditioning system.

[0004] Currently, the connection between ship air conditioning brackets and outdoor units is mostly a rigid connection, meaning they are tightly fixed together with bolts. The brackets are typically welded or bolted to the deck or hull plating. However, this connection structure has certain drawbacks. During operation, the outdoor unit inevitably generates mechanical vibrations, which are directly transmitted to the deck or hull plating through the bracket. This vibration can cause resonance in the ship's metal components, generating noise within the cabin. This noise severely interferes with the crew's rest, and prolonged exposure to such an environment can even affect their work performance and health. Therefore, a shipborne air conditioning vibration damping and noise reduction bracket device is proposed to address these problems. Utility Model Content

[0005] The purpose of this invention is to solve the problems mentioned in the background art, and thus propose a shipborne air conditioning vibration damping and noise reduction bracket device. This invention, through the design of a positioning mechanism, allows for soft contact fixation between the crossbar and the support plate, buffering the vibration transmission of the crossbar and protecting the support plate and mounting bracket from strong vibrations. This effectively reduces cabin noise caused by vibration, creating a quieter resting environment for the crew and enhancing their comfort during rest.

The sound insulation cover adopts a multi-layer composite structure, mainly composed of glass wool to form a sound absorption layer, sound insulation felt to form a sound insulation layer, and galvanized steel plate to form a protective layer, which improves the overall aesthetics. Sound absorption cotton is fixedly connected to the inner wall of the sound insulation cover. The sound absorption cotton is mainly made of rock wool. The front and bottom of the sound insulation cover are open structures. Through the opening design, it is beneficial to the heat dissipation of the air conditioner outdoor unit and avoids heat accumulation inside the sound insulation cover.

[0009] Preferably, a plug rod is penetrated and slidably connected to the inner wall of the sound insulation cover. The plug rod is in a "C" - shaped rod structure.

[0016] Preferably, the end of the ball plunger away from the return spring passes through the collar and is inserted into the inner wall of the limiting hole.

[0028] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0029] like Figures 1-3 As shown, one embodiment of this utility model is provided: a shipborne air conditioner vibration damping and noise reduction bracket device, including a mounting frame 1, a support plate 2 fixedly connected to the side wall of the mounting frame 1, and a crossbar 3 snapped onto the top of the mounting frame 1. The mounting frame 1, the support plate 2 and the crossbar 3 are assembled together to form an air conditioner bracket. The mounting frame 1 can be fixed to the ship deck or hull plate with bolts. The support plate 2 can provide support for the crossbar 3. The crossbar 3 can be fixed to the air conditioner outdoor unit with bolts. The top of the mounting frame 1 is provided with a positioning mechanism 4 and a noise reduction mechanism 5.

[0030] like Figures 2-3 As shown, the positioning mechanism 4 includes a positioning block 41, which is fixedly connected to the top of the support plate 2. A rubber pad 42 is fixedly connected to the outer wall of the positioning block 41. The cross-sections of the rubber pad 42 and the crossbar 3 are both "U" shaped. The outer wall of the rubber pad 42 is attached to the inner wall of the crossbar 3. Since the cross-section of the crossbar 3 is "U" shaped, the positioning block 41 inside it can limit the front and rear sides of the crossbar 3. At the same time, the rubber pad 42 on the outer wall of the positioning block 41 can separate it from the crossbar 3, avoiding hard contact between the crossbar 3 and the positioning block 41.

[0031] like Figures 2-4As shown, a positioning shaft 43 is fixedly connected to the top of the positioning block 41, and a silicone sleeve 44 is fixedly connected to the outer wall of the positioning shaft 43. The positioning shaft 43, in conjunction with the U-shaped groove 412, can limit the left and right ends of the crossbar 3. The silicone sleeve 44 on the outer wall of the positioning shaft 43 can separate it from the crossbar 3, preventing hard contact between the positioning shaft 43 and the crossbar 3. A collar 45 is rotatably connected to the outer wall of the positioning shaft 43, and a positioning rod 46 is fixedly connected to the outer wall of the collar 45. A rubber block 47 is fixedly connected to the bottom end of the positioning rod 46. The positioning rod 46, in conjunction with the rubber block 47, can limit the height of the crossbar 3. Simultaneously, the rubber block 47... The positioning rod 46 can be separated from the crossbar 3 to avoid hard contact between the positioning rod 46 and the crossbar 3. The inner wall of the positioning rod 46 is slidably connected to a ball plunger 48. The inner wall of the positioning rod 46 is fixedly connected to a return spring 49. One end of the ball plunger 48 is a hemispherical structure. When the ball plunger 48 is pushed, the spherical surface will be squeezed, thereby pushing the ball plunger 48 into the interior of the positioning rod 46. The other end of the ball plunger 48 is fixedly connected to the return spring 49. The elasticity of the return spring 49 can push the ball plunger 48, so that the ball plunger 48 slides and returns to its original position on the inner wall of the positioning rod 46.

[0032] like Figure 4 As shown, the outer wall of the positioning shaft 43 is provided with a disassembly hole 410 and a limiting hole 411. The transverse central axis of the disassembly hole 410 and the limiting hole 411 are coaxial. Both the disassembly hole 410 and the limiting hole 411 are semi-circular hole structures with one side opening. The semi-circular hole structure facilitates the movement of the ball plunger 48 out of the hole. The end of the ball plunger 48 away from the return spring 49 passes through the collar 45 and is inserted into the inner wall of the limiting hole 411. The ball plunger 48 and the collar 45 are slidably connected at the through-hole. When the ball plunger 48 is inserted into the limiting hole 411, the positioning rod 46 and the rubber block 47 can be fixed to the top of the crossbar 3. When the ball plunger 48 is inserted into the disassembly hole 410, the positioning rod 46 and the rubber block 47 can be fixed above the U-shaped groove 412, so that the positioning rod 46 and the rubber block 47 can be removed from the top of the crossbar 3.

[0033] like Figure 3 As shown, both ends of the crossbar 3 are provided with U-shaped grooves 412. The inner diameter of the U-shaped grooves 412 is the same as the outer diameter of the silicone sleeve 44. The crossbar 3 is engaged with the outer wall of the silicone sleeve 44 through the U-shaped grooves 412 at both ends. The positioning shaft 43, in conjunction with the U-shaped grooves 412, can limit the left and right ends of the crossbar 3. The silicone sleeve 44 on the outer wall of the positioning shaft 43 can separate it from the crossbar 3, avoiding hard contact between the positioning shaft 43 and the crossbar 3.

[0034] like Figure 3As shown in the figure, the noise reduction mechanism 5 includes a sound insulation cover 51. The inner wall of the sound insulation cover 51 is fixedly connected with sound-absorbing cotton 52. The sound insulation cover 51 and the sound-absorbing cotton 52 inside it can absorb the high-frequency noise generated by the operation of the air conditioner outdoor unit, thereby effectively reducing the range of noise transmission generated by the operation of the air conditioner outdoor unit itself, reducing the noise impact on the cabin. The front and bottom of the sound insulation cover 51 are open structures, and the openings in the front and bottom of the sound insulation cover 51 are beneficial for the heat dissipation of the air conditioner outdoor unit.

[0035] As Figure 3 shown in the figure, a plug rod 53 penetrates and is slidably connected to the inner wall of the sound insulation cover 51. The plug rod 53 is in the shape of a "匚" rod. A jack 54 for inserting the plug rod 53 is opened on the inner wall of the positioning block 41. The plug rod 53 is inserted into the inner wall of the jack 54. Push the plug rod 53 to insert it into the inside of the jack 54. The plug rod 53 and the jack 54 can be used to limit the position of the sound insulation cover 51, so that the sound insulation cover 51 can be fixed on the outside of the air conditioner outdoor unit.

[0036] As Figure 3 [[ID=**10**]]shown in the figure, a limiting spring 55 is sleeved on the outer wall of the plug rod 53. One end of the limiting spring 55 is fixedly connected to the outer wall of the sound insulation cover 51, and the other end of the limiting spring 55 is fixedly connected to the outer wall of the plug rod 53. When the plug rod 53 is pulled to gradually slide out of the sound insulation cover 51, the plug rod 53 will stretch the limiting spring 55. When the plug rod 53 is released, the elasticity of the limiting spring 55 can drive the plug rod 53 to slide back to its original position on the inner wall of the sound insulation cover 51.

[0037] Working principle: The limiting hole 411, in conjunction with the ball plunger 48, can limit the collar 45, keeping the positioning rod 46 on the outer wall of the collar 45 in a fixed state. At this time, the positioning rod 46 will drive the rubber block 47 to adhere to the upper surface of the crossbar 3. The positioning rod 46, in conjunction with the rubber block 47, can limit the height of the crossbar 3, keeping the crossbar 3 confined to the upper surface of the support plate 2. At the same time, the rubber block 47 can separate the positioning rod 46 from the crossbar 3, preventing hard contact between the positioning rod 46 and the crossbar 3. Meanwhile, the positioning shaft 43, in conjunction with the U-shaped groove 412, can limit the left and right ends of the crossbar 3. The silicone sleeve 44 on the outer wall of the positioning shaft 43 can separate it from the crossbar 3, preventing hard contact between the positioning shaft 43 and the crossbar 3. Since the crossbar 3 has a "U" shaped cross-section, the positioning block 41 inside can limit the front and rear sides of the crossbar 3. At the same time, the rubber pad 42 on the outer wall of the positioning block 41 can... To separate the horizontal bar 3 from the positioning block 41, preventing hard contact between the horizontal bar 3 and the positioning block 41, the positioning block 41, in conjunction with the positioning shaft 43, U-shaped groove 412, and positioning rod 46, can restrict the horizontal bar 3 in all directions, thus completely fixing the horizontal bar 3 above the support plate 2. Then, the air conditioner outdoor unit can be fixed to the top of the horizontal bar 3 with bolts. At this time, the silicone sleeve 44 can be used to separate the positioning shaft 43 from the horizontal bar 3, the rubber pad 42 can be used to separate the positioning block 41 from the horizontal bar 3, and the rubber block 47 can be used to separate the positioning rod 46 from the horizontal bar 3, so that the horizontal bar 3 maintains soft contact with the positioning block 41, the positioning shaft 43, and the positioning rod 46. When the vibration generated during the operation of the air conditioner is transmitted to the horizontal bar 3, the rubber pad 42, silicone sleeve 44, and rubber block 47 can effectively reduce the vibration transmission, so that the support plate 2 and the mounting bracket 1 are no longer subjected to strong vibration interference, thereby effectively reducing the noise generated by vibration in the cabin.

[0038] Pushing the positioning rod 46 causes the collar 45 to rotate on the outer wall of the positioning shaft 43. At this time, the spherical surface of the ball plunger 48 is squeezed by the limiting hole 411, causing the ball plunger 48 to slide towards the inner wall of the positioning rod 46 and compress the return spring 49. At this time, the ball plunger 48 will gradually disengage from the limiting hole 411. When the collar 45 moves the ball plunger 48 to the disassembly hole 410 during rotation, the elasticity of the return spring 49 can push the ball plunger 48, causing the ball plunger 48 to insert into the disassembly hole 410. At this time, the ball plunger 48, in conjunction with the disassembly hole 410, can limit the collar 45, thus fixing the positioning rod 46. At this time, the positioning rod 46 will drive the rubber block 47 to be fixed directly above the U-shaped groove 412. At this time, the positioning rod 46 and the rubber block 47 no longer restrict the height of the crossbar 3, and the crossbar 3 can be directly removed from the outer wall of the positioning shaft 43, thereby improving the disassembly efficiency of the crossbar 3 for maintenance of the air conditioner outdoor unit.

[0039] After the outdoor unit of the air conditioner is fixed to the crossbar 3 with bolts, first pull the plug rod 53 to gradually slide it out of the soundproof cover 51 and stretch the limiting spring 55. Then, cover the outside of the outdoor unit with the soundproof cover 51 and align the plug rod 53 with the insertion hole 54 on the positioning block 41. Then push the plug rod 53 to insert it into the inside of the insertion hole 54, so that the limiting spring 55 can elastically return to its original position. At this time, under the elastic action of the limiting spring 55, the plug rod 53 can maintain a stable insertion state. At this time, the plug rod 53 and the insertion hole 54 can limit the soundproof cover 51, so that the soundproof cover 51 can be fixed to the outside of the outdoor unit of the air conditioner. Covering the outdoor unit with the soundproof cover 51 can block the noise transmission path. At the same time, the sound-absorbing cotton 52 inside the soundproof cover 51 can absorb the high-frequency noise generated by the operation of the outdoor unit of the air conditioner, thereby effectively reducing the noise transmission range generated by the operation of the outdoor unit of the air conditioner.
