Description

Technical Field

[0001] The invention relates to the field of noise monitors, and in particular to an environmental noise monitor. Background Art

[0002] An environmental noise monitor is a device used to measure and record the noise level in the surrounding environment. It is widely used in urban planning, environmental protection, industrial production, traffic management, construction and other fields. Noise measurement can measure the intensity of environmental noise in real time, usually in decibels (dB). It records noise data over a period of time for analysis and reporting. Some high-end devices support wireless data transmission and send data to a remote server or platform via Bluetooth, Wi-Fi or 4G / 5G networks.

[0003] Fixed noise monitoring stations are installed in fixed locations and work continuously for long periods of time. They are usually used for large-area environmental monitoring and are suitable for urban noise mapping, industrial area environmental monitoring, etc. By properly selecting and using environmental noise monitors, noise pollution can be effectively evaluated and managed, the living and working environment can be improved, and public health can be protected.

[0004] When conducting outdoor environmental noise monitoring, it is necessary to install a noise monitor outdoors for a long period of unmanned monitoring. The noise data recorded by the monitor can be used to analyze the noise intensity of the surrounding environment. However, the existing noise monitors do not have active rain and wind protection functions. When encountering extreme weather changes, staff are required to protect or dismantle the noise monitoring instrument in time to prevent the microphone from getting damp or damaged by bumps. When the weather is normal, the protective gear needs to be removed to prevent the protective gear from affecting the noise monitoring accuracy of the microphone. The whole process is too cumbersome, and when the extreme weather changes too quickly, it is difficult to protect multiple monitoring instruments in different locations in the first time, which can easily cause damage to the monitoring instruments.

[0005] Therefore, it is necessary to provide an environmental noise monitor to solve the above technical problems. Summary of the invention

The problem that the existing noise monitor does not have active rain and wind protection functions, and when extreme weather changes too quickly, it is difficult to protect multiple monitoring instruments at different locations in the first place, which easily causes damage to the monitoring instruments is solved.

The shielding cover 29 is made of aluminum alloy, is light in weight and has strong protective ability. A water outlet is provided at the bottom of the shielding cover 29. A stopper 35 is fixed on the support column 3 and located between the fixed cylinder 15 and the shielding cover 29. Four transmission ropes 30 are fixed on the bearing 4. The bearing 4 is provided with a wire groove adapted to the transmission rope 30, and the bottom ends of the four transmission ropes 30 are fixed to the inner wall of the shielding cover 29. The bearing 4 drives the transmission through the first transmission wheel 32 and the second transmission wheel 34. The moving rope 30 makes the transmission rope 30 wind around in the wire groove on the bearing 4, and the transmission rope 30 pulls the shielding cover 29 at the bottom to move upward. A first support block 31 is fixed on the support column 3 and located inside the enclosure 8. A first transmission wheel 32 is arranged on the first support block 31 and corresponds to the bearing 4, and the first transmission wheel 32 is connected to the transmission rope 30 in transmission.

[0022] The working principle of the environmental noise monitor provided by the present invention is as follows: when performing environmental noise monitoring, a suitable position is selected, the base 1 of the device of the present invention is fixed by fixing bolts 39, the surrounding environmental noise is received by the microphone 20, and the data is transmitted to the monitoring device inside the monitoring cabinet 2 through the signal line 40, so as to obtain the noise data; When it rains, the rain cover 44 is used to block the rain, and at the same time, rainwater falls into the water storage tank of the water receiving tray 10 through the enclosure 8, so that the overall weight of the water receiving tray 10 increases and exceeds the elastic force of the spring 16 and the elastic force of the spring sheet 28. At the same time, the water receiving tray 10 becomes heavier and continues to slide downward, pressing the long rod 9 to shrink the long rod 9, and driving the sound receiver 20 on the bracket 19 to move toward the protective tube 25 through the connecting rod 18. When the baffle 21 on one side of the sound receiver 20 hits the inside of the protective tube 25 and drives the protective tube 25 to move along the narrowed side of the inclined slot 26, the two protective tubes 25 shrink at the same time, as shown in FIG. Figure 8 As shown, when the microphone 20 is moved to the narrowest part of the inclined slot 26, the two protective tubes 25 completely wrap the microphone 20, and the bracket 19 extends through the slot 37 on the protective tube 25. The sealing gasket 42 between the two protective tubes 25 improves the sealing performance, so that the microphone 20 is further protected from rain at the first time; When the rain stops, the drain pipe 38 at the bottom of the water receiving tray 10 slowly drains the water. After the rainwater in the water receiving tray 10 is drained, the weight of the water receiving tray 10 becomes lighter and is less than the elastic force of the spring 16. The elastic force of the spring 16 drives the moving cylinder 14 to move upward, drives the long rod 9 to unfold through the linkage rod 17, drives the sound receiver 20 on the bracket 19 to unfold and move outward through the connecting rod 18, and drives the protective cylinder 25 at the same time. Through the elastic force of the spring sheet 28 between the two protective cylinders 25, the two protective cylinders 25 are driven to unfold and move along the widened side of the inclined slot 26 while unfolding, and completely expose the sound receiver 20 to collect noise; When the wind blows, the wind force becomes stronger and blows the wind cup 6. When the wind force is greater than the weight of the shielding cover 29, the wind cup 6 drives the rotating cover 5 and the bearing 4 to rotate. The bearing 4 drives the transmission rope 30 through the transmission of the first transmission wheel 32 and the second transmission wheel 34, so that the transmission rope 30 is wound in the wire groove on the bearing 4. The transmission rope 30 pulls the shielding cover 29 at the bottom to move upward, so that the shielding cover 29 moves to the sound receiver 20 and is limited by the block 35. The shielding cover 29 shields and protects the surroundings of the sound receiver 20 to prevent the flying sand and gravel from directly hitting the sound receiver 20. When the wind force decreases, the shielding cover 29 depends on gravity to descend again.
