Specific implementation manner

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0021] As Figures 1-4 shown, it relates to a noise detection device that is easy to install, including a base 1. Two foot holes are provided on the outer wall of the base 1. Foot nails 2 are slidably connected to the inner walls of the two foot holes. A column 3 is fixedly connected to the top of the base 1. A T-shaped shaft is fixedly connected to the outer wall of the column 3. A vertical rod 4 is rotatably sleeved on the outer wall of the T-shaped shaft. A round sleeve 5 is threadedly sleeved on the outer wall of the vertical rod 4. The inner wall of the round sleeve 5 is slidably connected to the outer wall of the column 3. Rotate the round sleeve 5 so that the inner wall of its bottom is no longer in contact with the outer wall of the column 3. The vertical rod 4 can rotate through the column 3, so that the whole above the vertical rod 4 rotates downward. A display screen 6 is fixedly connected to the outer wall of the vertical rod 4.

[0022] Four air spring shock absorbers 7 are fixedly connected to the top of the vertical rod 4. The four air spring shock absorbers 7 are fixedly connected to the same mounting plate 8. The air spring shock absorber 7 uses the compressibility of gas to achieve the shock absorption effect, reduce vibration transmission, and reduce the impact on the noise sensor body 16. Two rectangular rubber cushion blocks 9 are placed on the top of the mounting plate 8. The rectangular rubber cushion blocks 9 elastically support the separation plate 10. The two rectangular rubber cushion blocks 9 are fixedly connected to the same separation plate 10. A noise sensor body 16 (OSEN-Z-69) is fixedly connected to the top of the separation plate 10. The noise sensor body 16 (OSEN-Z-69) has waterproof performance, and in actual use, a rain shelter can be added above the whole. The noise sensor body 16 (OSEN-Z-69) detects the sound signal and converts it into an electrical signal. The noise sensor body 16 (OSEN-Z-69) usually has a capacitive electret microphone sensitive to sound. When the sound wave acts on the microphone, it will cause the electret film in the microphone to vibrate, resulting in a change in capacitance and thus generating a corresponding tiny voltage.

[0023] The outer wall of the mounting plate 8 is provided with a quick-release mechanism. The quick-release mechanism includes two shaft bodies 13. Two docking blocks 11 are fixedly connected to the bottom of the separation plate 10. Two rectangular docking holes are opened at the top of the mounting plate 8. The outer walls of the two docking blocks 11 are respectively slidably connected to the inner walls of the two rectangular docking holes. Rectangular docking grooves 12 are opened on the outer walls of the two docking blocks 11. The rectangular docking grooves 12 cooperate with the lever 14 to prevent the docking blocks 11 from detaching from the mounting plate 8. The tops of the two shaft bodies 13 are fixedly connected to the bottom of the mounting plate 8.

[0024] Rotating sleeves are sleeved on the outer walls of the two shaft bodies 13. The lever 14 rotates through the shaft body 13. One ends of the two levers 14 are respectively located inside the two rectangular docking grooves 12. Torsion springs 15 are sleeved on the outer walls of the two shaft bodies 13. One end of the torsion spring 15 is fixedly connected to the outer wall of the shaft body 13. The other end of the torsion spring 15 is fixedly connected to the outer wall of the lever 14. Due to the elastic force of the torsion spring 15 itself, one end of the lever 14 is located inside the rectangular docking groove 12 when not subjected to external force.

[0025] Working principle: When in use, place the base 1 in a suitable position and away from the temporary construction equipment, and fix it to the ground through the two foot nails 2. The base 1 is fixed to the ground. The column 3 and the vertical rod 4 are limited by the circular sleeve 5 to prevent rotation between them. Subsequently, if maintenance is required, the circular sleeve 5 can be rotated so that the inner wall of its bottom is no longer in contact with the outer wall of the column 3, exposing the rotation point between the column 3 and the vertical rod 4. The vertical rod 4 rotates through the column 3, causing the entire upper part of the vertical rod 4 to rotate downward, eliminating the need for climbing for maintenance, which is convenient for maintaining the noise sensor body 16. During maintenance, rotate the two levers 14 to overcome the elastic force of the torsion springs 15 and make them parallel to the two docking blocks 11, so that one ends of the two levers 14 are no longer located inside the two rectangular docking grooves 12, releasing the limit on the two docking blocks 11. Take out the separation plate 10 from the mounting plate 8, and the two docking blocks 11 slide out through the two rectangular docking holes, forming a quick-release operation, which is convenient for maintaining the noise sensor body 16 alone. At the same time, after maintenance, fix the separation plate 10 to the mounting plate 8 again through the quick-release mechanism, rotate the vertical rod 4 to make it vertical, and rotate the circular sleeve 5 to sleeve it on the outer wall of the column 3, restricting the rotation between the column 3 and the vertical rod 4. During normal use, after the column 3 and the vertical rod 4 are vibrated, the vibration is transmitted to the four air spring shock absorbers 7 for shock absorption. The air spring shock absorbers 7 utilize the compressibility of gas to achieve the shock absorption effect and reduce the impact on the noise sensor body 16.

The special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, welding, etc. that are mature in the prior art.

In addition, the circuit connection adopts the conventional connection method in the prior art, which will not be elaborated here. Moreover, for the components known to those skilled in the art, their structures and principles can all be known by those skilled in the art through technical manuals or by conventional experimental methods.
