From a physiological point of view, any sound that interferes with people's normal rest, study and work, and any sound that interferes with the sound people want to hear. In this sense, there are many sources of noise, such as the sound of cars on the street, the sound of people talking in a quiet library, the sound of machines on a construction site, and the excessive sound of a neighbor's TV. In the field of communications, the energy field that interferes with signal transmission is called noise. The source of this energy field can come from the internal system or from the external environment. Generally, people use decibels to measure the intensity of noise and use the signal-to-noise ratio to measure the degree of noise's impact on useful signals. Possible sources of noise include airplanes, cars, factories, construction sites, daily life, etc. Noise is one of the environmental pollution.

DETAILED DESCRIPTION

[0020] In order to make it easier to understand the structure of the present invention and the functional features and advantages that can be achieved, the preferred embodiments of the present invention are described in detail with reference to the drawings as follows:

[0021] Example:

[0022] like Figures 1 to 3 As shown, an embodiment of the utility model provides a noise monitoring device for an airport, including a protective box 1 and a noise monitoring device 10. The noise monitoring device 10 uses a noise tester with model 2310SL, which belongs to the prior art and is not described in detail. The noise monitoring device 10 is located inside the protective box 1, and is characterized in that it also includes: a protective plate 6, a sound receiving opening 2 is opened on the top of the protective box 1 for receiving sound, a side opening 3 is opened on the side of the protective box 1, and the protective plate 6 is configured to be movably connected between the sound receiving opening 2 and the side opening 3, and is in contact with the bottom of the sound receiving opening 2 or the side wall of the side opening 3 when it moves to the terminal position.

[0023] The sound receiving opening 2 is provided to facilitate receiving the noise above the airport when the aircraft takes off and lands, thereby avoiding poor sound receiving effect due to the obstruction of the protective baffle 8. The sound receiving opening 2 is blocked by the movably connected protective plate 6 when it rains, thereby preventing rainwater from entering the protective box 1 and causing damage to the noise monitoring device 10.

[0024] like Figure 1 As shown, guide grooves 4 are provided on the side walls of the sound receiving opening 2, and the guide grooves 4 are set to be smoothly inclined downward toward the side opening 3. By providing the guide grooves 4, it is convenient to guide the falling rainwater to prevent the rainwater from directly entering the protective box 1.

[0025] like Figure 1 and Figure 2As shown, drainage ports 5 are provided at both sides of the top of the side opening 3, and the drainage ports 5 are connected to the bottom of the guide groove 4. The drainage ports 5 are provided to facilitate the drainage of rainwater guided by the guide groove 4 from the front end of the protection box 1 to prevent continuous accumulation of rainwater.

[0026] like Figure 2 and Figure 3 As shown, a baffle plate 8 is provided near the side opening 3 inside the protection box 1, and the height of the baffle plate 8 does not exceed half of the height of the protection plate 6. By providing the baffle plate 8, when the protection plate 6 is raised, the side opening 3 on the side of the protection box 1 is protected to a certain extent, and debris is prevented from entering the protection box 1 through the side opening 3. At the same time, its height is less than half of the protection plate 6, so that the movement of the protection plate 6 is not blocked.

[0027] like Figure 3 As shown, a second ear plate 14 and a third ear plate 15 are symmetrically provided on both sides of one side of the protection plate 6 close to the inside of the protection box 1 , and the second ear plate 14 is located below the third ear plate 15 .

[0028] A first ear plate 13 is provided at the top of the side opening 3. The first ear plate 13 is rotatably connected to a suspension rod 11 in cooperation with the inner wall of the protective box 1. The suspension rod 11 is in a J-shaped structure. The bending position of one end of the suspension rod 11 away from the first ear plate 13 is rotatably connected to the third ear plate 15. Two suspension rods 11 are provided, and the middle section of the suspension rod 11 is located on both sides of the protective plate.

[0029] An electric push rod 9 is provided on the inner bottom wall of the protective box 1. The electric push rod 9 is located on the side of the baffle 8 close to the side opening 3. The electric push rod 9 is vertically arranged, and the top output end is fixedly connected to the lifting seat 12. The end of the lifting seat 12 is rotatably connected with the second ear plate 14. Both ends of the lifting seat 12 are provided with protruding connecting parts that are rotatably connected with the second ear plate 14. Preferably, there are two electric push rods 9, which are symmetrically arranged on both sides of the bottom 12 of the lifting seat to ensure the support stability of the lifting seat 12.

[0030] The protective plate 6 is driven to rise by an electric push rod 9, and the suspension rod 11 is limited at the same time, so that the upper area of ​​the protective plate 6 makes a circular motion along the first ear plate 13, so that the protective plate 6 changes its inclination angle while rising, and finally completes the blocking of the bottom of the sound receiving opening 2.

[0031] like Figure 1 As shown, a groove 7 is provided on one side of the protective plate 6 away from the inside of the protective box 1, and an opening is provided at the end of the groove 7 close to 3 when the protective plate 6 is raised. By providing the groove 7, when the protective plate 6 is used as a rain shield, rainwater dripping on the protective plate 6 is guided and discharged to the end close to the side opening 3.

[0032] The working principle of the utility model is as follows: when in use, the protective plate 6 is at the side opening 3 position, and a rectangular enclosure is formed by the protective plate 6 in cooperation with the side wall of the protective box 1 to frame the noise monitoring device 10, so as to prevent debris or small animals and insects from entering the interior of the protective box 1 and affecting the sound reception. The sound reception opening 2 provided at the top of the protective box 1 makes the top of the noise monitoring device 10 transparent, so as to better receive the noise transmitted from the aircraft during takeoff and landing, thereby improving the monitoring accuracy. In rainy and snowy weather, the electric push rod 9 is started to drive the lifting The seat 12 rises, and the lifting seat 12 drives the protective plate 6 to rise as a whole, and through the rotation limiting effect of the suspension rod 11, while the protective plate 6 rises as a whole, the upper end part of the protective plate 6 is retracted toward the inside of the protective box 1, and finally approaches the bottom of the sound receiving opening 2. At this time, the guide groove 4 and the groove 7 on the protective plate 6 cooperate to guide the rainwater dripping on the top of the device to the side close to the side opening 3, so as to prevent the rainwater from entering the protective box 1 and damaging the noise monitoring device 10. At this time, the baffle 8 blocks the rainwater floating in from the side opening 3 to a certain extent.

[0033] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
