[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.
[0029] Example
[0030] In one embodiment of this utility model, reference is made to Figure 1 and 2 As shown, this utility model provides a noise testing chamber, comprising:
[0031] The soundproof enclosure body 3 has an inlet 6 and an outlet on its side wall, with the inlet 6 and outlet facing each other. The noise level inside the soundproof enclosure body 3 under natural conditions is 45 decibels. The dimensions of the soundproof enclosure body 3 are 2 meters high, 2 meters wide, and 2 meters long.
[0032] The transfer module includes a transfer channel 5 formed by multiple electric rollers 8 arranged in parallel. The transfer channel 5 passes through the inlet 6 and the outlet. Limiting structures are provided on both sides of the transfer channel 5 to limit the turnover board and prevent it from falling. Multiple guide rollers 14 are provided on the limiting structures. The multiple guide rollers 14 are arranged above the transfer channel 5. The rotation axis of the guide rollers 14 is perpendicular to the plane where the multiple electric rollers 8 are located. The multiple guide rollers 14 are distributed along the conveying direction of the transfer channel 5. When the edge of the turnover board contacts the guide roller 14, it drives the guide roller 14 to rotate. The distance from the multiple guide rollers 14 to the middle of the transfer channel 5 decreases sequentially, so as to gradually guide the turnover board towards the middle of the transfer channel 5.
[0033] The test module, located inside the soundproof enclosure 3, is used to collect, analyze, and process motor noise.
[0034] In one embodiment of this utility model, the inner layer of the soundproof box body 3 is provided with a sound-absorbing cotton layer with a thickness of 8 cm, which is used to exhaust external noise and ensure the accuracy of the test results.
[0035] In one embodiment of this utility model, the wall interlayer of the soundproof box body 3 is composed of fireproof sound insulation cotton, medium density board and nylon board, in order to improve the structural strength and sound insulation performance of the soundproof box body 3.
[0036] In one embodiment of this utility model, reference is made to Figure 1 and 2 As shown, the interior of the soundproof enclosure 3 is equipped with multiple lights and multiple soundproof windows 23, allowing operators to observe the progress of operations inside the enclosure without entering. The enclosure 3 is also equipped with an entrance / exit 1, which facilitates personnel access to the enclosure for related operations. The entrance / exit 1 is equipped with control buttons 2, a control computer, and a keyboard and mouse box, allowing operators to complete the testing process from outside the entrance / exit 1.
[0037] In one embodiment of this utility model, reference is made to Figure 1As shown, it also includes a limiting module disposed within the soundproof box body 3. The limiting module includes a limiting block 9 and a driver 15. The limiting block 9 is rotatably disposed below the transmission channel 5. The output end of the driver 15 drives the limiting block 9 to rotate by extending and retracting. The limiting block 9 is configured to extend out of the gap between the two electric rollers 8 by rotation and limit the turnover plate on the transmission channel 5 for detection. The gap has a certain width, but is not wider than the width of the turnover plate. The driver 15 is implemented as a cylinder.
[0038] In one embodiment of this utility model, reference is made to Figure 2 and 4 As shown, the limiting block 9 is provided with a transmission roller 10, which is disposed between the gaps of the two electric rollers 8. The rotation axis of the transmission roller 10 is parallel to the rotation axis of the electric roller 8, and the top of the transmission roller 10 is flush with the plane on which the multiple electric rollers 8 are located. Since the gap has a certain width, the transmission roller 10 plays the role of supporting and driving the turnover plate.
[0039] In one embodiment of this utility model, reference is made to Figure 2 As shown, the limiting structure includes a limiting strip 19 and a limiting plate 16. The limiting strip 19 and the limiting plate 16 are respectively disposed on both sides of the transmission channel 5. The limiting plate 16 is disposed parallel to the plane in which the plurality of electric rollers 8 are located. The guide roller 14 is disposed on the limiting strip 19.
[0040] In one embodiment of this utility model, reference is made to Figure 1 and 2 As shown, the transfer module also includes a return channel 7, which is also composed of multiple rotating rollers and electric rollers 8. The return channel 7 passes through the inlet 6 and the outlet, and is located below the transmission channel 5. The transmission direction of the return channel 7 is opposite to that of the transmission channel 5. The empty turnover plate is loaded and flows back to the upstream to retransmit the motor.
[0041] In one embodiment of this utility model, reference is made to Figure 2 As shown, the transmission channel 5 also includes multiple rotating rollers, and the multiple rotating rollers and multiple electric rollers 8 are arranged in combination to form the transmission channel 5, wherein the electric rollers 8 are disposed at both ends of the transmission channel 5.
[0042] In one embodiment of this utility model, reference is made to Figure 1 As shown, multiple lifting rings 4 are evenly distributed on the top of the soundproof box body 3 to facilitate the hoisting of the soundproof box body 3. The soundproof box body 3 is provided with a bracket 20, which is used to support the transmission channel and the return channel 7. The lifting rings 4 are set on the top of the bracket 20.
[0043] In one embodiment of this utility model, reference is made to Figure 2 As shown, the soundproof box body 3 is also provided with a support platform, which is used to install detection-related devices.
[0044] In one embodiment of this utility model, reference is made to Figure 3 As shown, the test module includes a sound collector and a display 16. After the sound collector collects noise, it displays the data on the display 16 to visualize the data.
[0045] The working principle of the noise testing chamber described in this utility model is as follows:
[0046] Upstream of the transmission channel 5, the motor to be tested is placed on the turnover plate. The motor and the turnover plate are efficiently transported to the silent box body 3 by the electric roller 8. The first guide roller 22 and the second guide roller 21 abut against the side of the turnover plate in sequence to guide the turnover plate. The turnover plate approaches the limiting plate 16. When the sensor 12 detects that the turnover plate is in place, the driver 15 drives the limiting block 9 to extend and limit and block the turnover plate. The electric roller 8 stops rotating. After the detection module 11 completes the detection, the limiting block 9 rotates, and the transmission roller 10 descends to be flush with the electric roller 8. The electric roller 8 starts to rotate and continues to transport the turnover plate and the motor. The turnover plate slides past the transmission roller 10 and continues to move. When the turnover plate moves to the downstream of the transmission channel 5, the motor is removed, and the empty turnover plate is put into the return channel 7 and sent back to the upstream loading.
[0047] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
