DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings:

[0021] Example 1: Please refer to Figure 1-6 In the present embodiment, a noise monitoring device for municipal green construction with adjustable height includes a base plate 1 and a round rod 4. The front and rear sides of the base plate 1 are rotatably connected to the inner sides of the outer walls of the two round rods 4 respectively. The round rods 4 are rotated by the force through the outer wall bearings of the base plate 1. The outer wall ends of the two round rods 4 are respectively connected to fixed structures 2. The four corners of the bottom of the base plate 1 are respectively fixed with rollers 5. The rollers 5 facilitate the overall position movement. Square frames 6 are fixedly connected to the left and right sides of the top of the base plate 1. Horizontal plates 7 are fixedly connected to the left and right sides of the inner wall of the square frame 6. The inner wall of the horizontal plate 7 is connected to a lifting structure 3.

[0022] The fixing structure 2 includes a bracket 201 and a first screw rod 202. The inner wall of the bracket 201 is fixedly connected to the outer wall end of the round rod 4. The upper and lower sides of the bracket 201 are respectively threadedly connected to the outer wall of the first screw rod 202. The first screw rod 202 is subjected to force to rotate up and down through the outer wall of the bracket 201. A handle 203 is fixedly connected to the inner side of the first screw rod 202. The handle 203 is convenient for driving the first screw rod 202 to rotate. A circular plate 204 is fixedly connected to the top of the first screw rod 202 located at the top. The left and right sides of the bracket 201 are respectively fixedly connected to curved plates 205. The inner wall of the curved plate 205 is slidably connected with a straight rod 206. The straight rod 206 is subjected to force to slide back and forth through the inner wall of the curved plate 205. A bent rod 207 is fixedly connected to the outer side of the straight rod 206. The bent rod 207 is convenient for driving the straight rod 206 to move. The inner side of the outer wall of the straight rod 206 is plugged into the circular opening of the outer wall of the bottom plate 1.

[0023] The bent rod 207 in the fixed structure 2 moves the straight rod 206 outward through the curved plate 205, so that the straight rod 206 is separated from the circular opening on the outer wall of the bottom plate 1, and then the bracket 201 cooperates with the round rod 4 to rotate 180 degrees. At this time, the circular plate 204 faces downward, and then the bent rod 207 moves the straight rod 206 inward through the curved plate 205, so that the inner side of the outer wall of the straight rod 206 is plugged into the circular opening on the outer wall of the bottom plate 1. Then the lower handle 203 rotates the first screw 202 downward, so that the circular plate 204 moves downward, so that the bottom of the circular plate 204 is pressed against the ground to complete the positioning. The above operation is installed so that the first screw 202 is located at the bottom, and then the straight rod 206 is plugged into the circular opening on the outer wall of the bottom plate 1. At this time, the lower handle 203 rotates the first screw 202 downward, so that the bottom cone position of the first screw 202 is inserted into the sand, thereby improving work efficiency and reducing the difficulty of using the height-adjustable noise monitoring device for municipal green construction.

[0024] The outer round opening of the horizontal plate 7 is slidably connected with the vertical rod 11, and the vertical rod 11 is subjected to the force to slide up and down through the outer round opening of the horizontal plate 7. The bottom of the vertical rod 11 is fixedly connected with a baffle 12, and the top of the vertical rod 11 is fixedly connected with a noise monitor 10. How to operate and use the noise monitor 10 is already a prior art, and no more elaboration is made on the model. The upper part of the outer wall of the vertical rod 11 is matched with the top round opening of the square frame 6. The lifting structure 3 includes a vertical cylinder 301 and a second screw 302. The upper part of the outer wall of the vertical cylinder 301 is provided with a plurality of screws. The square is rotatably connected to the inner wall of the horizontal plate 7, and the vertical tube 301 is rotated by the bearing on the inner wall of the horizontal plate 7. The inner wall of the vertical tube 301 is threadedly connected to the outer wall of the second screw 302. The outer wall of the second screw 302 is adjacent to the inner part of the top circular opening of the square frame 6. A ring 303 is fixed to the bottom of the outer wall of the vertical tube 301, and handles 304 are respectively fixed to the left and right sides of the ring 303. The handles 304 are convenient for rotating the ring 303. The top of the second screw 302 is fixed to the bottom of the noise monitor 10.

[0025] Working principle:

[0026] The sensor of the noise monitor 10 is usually manufactured using MEMS technology, and contains a piezoelectric ceramic crystal and a metal film. When the crystal is affected by sound waves, a tiny electrical signal will be generated, and the metal film plays a protective role. After the electrical signal is amplified and filtered, the electrical signal of the sound can be obtained. Next, the noise detector will perform digital signal processing on the electrical signal, including filtering, fast Fourier transform (FFT) and other processing, so as to obtain various parameters of the noise, such as sound level, frequency distribution, time distribution, etc. These parameters can be output through the display screen or output port of the noise detector, and can also be recorded and transmitted through wireless communication or memory cards.

[0027] Noise monitoring device fixed position:

[0028] Municipal green construction flat ground fixing:

[0029] Cooperate with the roller 5 at the bottom of the base plate 1 to move the entire device to the position designated by the municipal green construction, and then the bent rod 207 moves the straight rod 206 outward through the curved plate 205, so that the straight rod 206 is separated from the circular opening on the outer wall of the base plate 1, and then the bracket 201 cooperates with the round rod 4 to rotate 180 degrees. At this time, the circular plate 204 faces downward, and then the bent rod 207 moves the straight rod 206 inward through the curved plate 205, so that the inner side of the outer wall of the straight rod 206 is plugged into the circular opening on the outer wall of the base plate 1, and then the lower handle 203 rotates downward with the first screw 202 to move the circular plate 204 downward, so that the bottom of the circular plate 204 is pressed against the ground to complete the positioning.

[0030] Municipal green construction sand fixation:

[0031] The above-mentioned installation operation makes the first screw rod 202 located at the bottom, and then the straight rod 206 is plugged into the circular opening of the outer wall of the bottom plate 1. At this time, the handle 203 at the bottom drives the first screw rod 202 to rotate downward, so that the bottom pointed cone position of the first screw rod 202 is inserted into the sand.

[0032] Noise monitoring device height adjustment:

[0033] The user holds the handle 304 and rotates it, thereby cooperating with the ring 303 to rotate the vertical cylinder 301 on the inner wall of the horizontal plate 7. The rotating vertical cylinder 301 moves the second screw 302 upward through the square frame 6, and the moving second screw 302 moves the noise monitor 10 upward. Similarly, rotating the vertical cylinder 301 in the opposite direction can realize the downward movement of the noise monitor 10. When the noise monitor 10 moves up and down, it will move the vertical pole 11 up and down. The vertical pole 11 limits the noise monitor 10 and the second screw 302 to prevent the noise monitor 10 and the second screw 302 from rotating.

[0034] Example 2: Please refer to Figure 1-6 : In this embodiment, a height-adjustable noise monitoring device for municipal green construction also includes a curved rod 8 and a sheath 9, the inner sides of the two curved rods 8 are respectively fixedly connected to the left and right sides of the square frame 6, and the outer wall of the curved rod 8 is fixedly connected to the inner wall of the sheath 9.

[0035] Working principle:

[0036] When the noise monitoring device for municipal green construction with adjustable height is moved, the hand can hold the sheath 9 to exert force to make the curved rod 8 push or pull the device as a whole to move.
