Description

Technical Field

[0001] The utility model belongs to the technical field of motor detection, and particularly relates to a soundproof room for detecting a fan coil motor. Background Art

[0002] A soundproof room (also known as a silent room or an audio laboratory) is a specially designed room aimed at minimizing external noise interference as much as possible and achieving sound isolation or control. Such rooms are usually used for audio testing, music production, recording, speech research, noise control experiments, etc.

[0003] Most of the existing soundproof rooms reduce the noise inside the room through soundproof materials. However, the traditional laminated soundproof materials are not only difficult to achieve a good soundproof effect but also easily increase the construction cost of the soundproof room. Moreover, in order to facilitate the automatic entry and exit of the tested items, openings are often designed in the soundproof room. The traditional single-layer pneumatic door panels are difficult to closely fit and soundproof these openings, resulting in poor soundproof effect or sound leakage in the soundproof room.

[0004] A fan coil unit is the abbreviation of a fan coil unit, which is one of the terminal devices of an air conditioning system composed of a small fan, a motor, and a coil (air heat exchanger), etc. When chilled water or hot water flows through the coil, heat exchange occurs with the air outside the pipe, cooling, dehumidifying, or heating the air to adjust the indoor air parameters. It is a commonly used terminal device for cooling and heating. Since it is often installed indoors, strict requirements are imposed on its operating noise, and it needs to be detected during equipment production.

[0005] Therefore, aiming at the problem that the soundproof effect of the existing soundproof room for detecting a fan coil motor of an air conditioner is lacking and noise is easily leaked from the openings of the soundproof room, a soundproof room for detecting a fan coil motor is developed. By adding a multi-layer soundproof structure and a double-layer opening and closing soundproof structure to the soundproof room, the soundproof effect of the soundproof room can be effectively improved, and noise leakage from the openings of the room body can be effectively avoided.

[0025] Please refer to Figures 1-6 , the present utility model provides an embodiment: a soundproof room for detecting a fan coil motor, which includes a first belt conveyor 2, a second belt conveyor 3 and a third belt conveyor 7, and also includes a soundproof outer shell 1, an air isolation layer 5, a soundproof inner shell 6, an internal switch board 14 and an external switch board 21. The left and right inner walls of the soundproof inner shell 6 are provided with first mounting grooves 16 that are symmetrically distributed in the front and rear. A first cylinder 13 is fixedly connected in the first mounting groove 16. The lower end of the output end of the first cylinder 13 is fixedly connected with the internal switch board 14.

The first belt conveyor 2 and the second belt conveyor 3 are respectively installed at the left and right ends of the soundproof outer shell 1. The third belt conveyor 7 is arranged on the inner wall of the soundproof inner shell 6. Second mounting grooves 20 that are symmetrically distributed in the front and rear are opened at the left and right ends of the soundproof outer shell 1. A second cylinder 22 is fixedly connected in the second mounting groove 20. The lower end of the output end of the second cylinder 22 is fixedly connected with the external switch board 21.

[0027] Please refer to Figures 4-6, in this embodiment, internally limiting frames 15 symmetrically distributed front and back are fixedly connected to the inner walls at the left and right ends of the silent inner shell 6. The inner walls of the internally limiting frames 15 are in contact with the outer walls at the front and back ends of the internal switch board 14. During use, the internally limiting frames 15 can assist in limiting the internally switch board 14 that moves up and down and opens and closes, so as to improve the stability of the internal switch board 14 when it opens and closes. Externally limiting frames 18 symmetrically distributed front and back are fixedly connected to the left and right ends of the silent outer shell 1. The inner walls of the externally limiting frames 18 are in contact with the outer wall of the external switch board 21. During use, the externally limiting frames 18 can assist in limiting the external switch board 21 that moves up and down and opens and closes, so as to improve the stability of the external switch board 21 when it opens and closes. The third groove 19, the second groove 17 and the first groove 12 are interconnected. Third grooves 19, second grooves 17 and first grooves 12 are respectively formed by penetrating the left and right ends of the silent outer shell 1, the air layer 5 and the silent inner shell 6. The third groove 19, the second groove 17 and the first groove 12 correspond to the external switch board 21 and the internal switch board 14 one by one. During use, the interconnected third groove 19, second groove 17 and first groove 12 can cooperate with the first belt conveyor 2 and the second belt conveyor 3 to convey the air conditioner motor from the outside of the silent room composed of the silent outer shell 1, the air layer 5 and the silent inner shell 6 to the inside.

[0028] Please refer to Figures 3-6 , in this embodiment, the left and right ends of the first bearing plate 8 are in contact with the left and right ends of the silent inner shell 6. The second bearing plate 9 and the third bearing plate 10 are respectively in contact with the left and right ends of the silent outer shell 1.

The upper ends of the second bearing plate 9 and the third bearing plate 10 are in contact with the lower end of the external switch board 21. The upper end of the first bearing plate 8 is in contact with the lower end of the internal switch board 14. During use, the first bearing plate 8, the second bearing plate 9 and the third bearing plate 10 can carry and protect the external switch board 21 and the internal switch board 14 that move up and down and open and close when they reach the bottom, so as to improve their service life and the degree of fit with the silent room composed of the silent outer shell 1, the air layer 5 and the silent inner shell 6. One end of the external switch board 21 close to the silent outer shell 1 is in contact with the left and right ends of the silent outer shell 1. One end of the internal switch board 14 close to the silent inner shell 6 is in contact with the inner walls at the left and right ends of the silent inner shell 6. During use, the external switch board 21 in contact with the outer wall of the silent outer shell 1 can improve the sound insulation tightness of the silent outer shell 1, and the internal switch board 14 in contact with the inner wall of the silent inner shell 6 can improve the sound insulation tightness of the silent inner shell 6.

[0029] During use, first place the air conditioner motor to be detected on the first conveyor belt 2, and the first conveyor belt 2 transports the air conditioner motor to the third trough 19 at the left end of the silent housing 1. Then start the first cylinder 13 and the second cylinder 22 to drive the internal switch plate 14 and the external switch plate 21 to lift and open along the inner walls of the internal limiting frame 15 and the external limiting frame 18, so that the air conditioner motor passes through the inner walls of the third trough 19, the second trough 17, and the first trough 12 and enters the silent room composed of the silent housing 1, the air separation layer 5, and the silent inner housing 6, and is transported to the third conveyor belt 7. Then the third conveyor belt 7 transports the air conditioner motor to the power-on detection location, and before detection, the first cylinder 13 and the second cylinder 22 drive the internal switch plate 14 and the external switch plate 21 to lift and close;

[0030] After the detection is completed, as described above, the first cylinder 13 and the second cylinder 22 drive the internal switch plate 14 and the external switch plate 21 to open and close, and the detected air conditioner motor is displaced outside the silent room through the first trough 12, the second trough 17, and the third trough 19 by the third conveyor belt 7, and then the second conveyor belt 3 transports the detected air conditioner motor outward;

[0031] During the detection, several groups of sound-absorbing wedges 11 in the silent inner housing 6 will absorb and isolate the motor noise, while the air separation layer 5 can reduce the efficiency of the motor noise in the silent inner housing 6 from spreading outward, so as to greatly improve the sound insulation effect of the silent room composed of the silent housing 1, the air separation layer 5, and the silent inner housing 6.

[0032] Through the above steps, the silent room composed of the silent housing 1, the air separation layer 5, and the silent inner housing 6 can reduce the leakage of noise during the detection of the air conditioner motor through multiple sound insulation methods. Among them, the air separation layer 5 can reduce the efficiency of noise spreading outside the silent room, and several groups of sound-absorbing wedges 11 can absorb and isolate the noise, thereby improving the sound insulation effect of the silent room. The inner and outer double-layer sound insulation door panels composed of the internal switch plate 14 and the external switch plate 21 can prevent the motor noise during detection from leaking out through the third trough 19, the second trough 17, and the first trough 12, thereby ensuring the sound insulation effect of the silent room, and thus solving the problem that the sound insulation effect of the existing silent room for detecting air conditioner motors is somewhat lacking and noise is easily leaked out from the opening of the silent room.

[0033] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the purpose of the present invention.
