Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1 , Figure 2 As shown, an environmentally friendly noise reduction device for construction management of building civil engineering includes: a first partition 1, a ventilation mechanism 2 is provided in the middle of the first partition 1; a telescopic plate 3, the telescopic plate 3 includes a first fixed plate 31 and a first movable plate 32, the first fixed plate 31 is rotatably connected to the first partition 1; a second partition 4, the second partition 4 is rotatably connected to the first movable plate 32; a side wall plate 5, the side wall plate 5 includes a second fixed plate 51 and a second movable plate 52, the second fixed plate 51 is detachably connected to the side wall of the first fixed plate 31, and the first movable plate 32 is detachably connected to the side wall of the first movable plate 32.

[0025] The first partition 1 is a square plate, and a cavity 11 is provided in the middle of the first partition 1. Sound-absorbing cotton (not shown in the figure) is pasted on the back wall of the first partition 1. When the baffle with the sound-absorbing cotton is placed next to the noise source, the sound-absorbing cotton can effectively block the sound from being transmitted outward, thereby reducing noise pollution at the construction site.

[0026] The ventilation mechanism 2 includes through holes 21, connecting pipes 22 and a fan 23. The through holes 21 are evenly spaced in the first partition 1 and are connected to the cavity 11. The connecting pipes 22 are opened in the side wall of the first partition 1 and connect the fan 23 and the cavity 11. During the sound insulation construction, the operating workers and machinery and equipment are covered by the device. The temperature inside the device is high, the ventilation is poor, and the operators cannot work for a long time. Therefore, when using the device for sound insulation and noise reduction, the fan 23 is started. The fan 23 has a silent function. The wind blown out enters the cavity 11 from the connecting pipe 22, and blows from the cavity 11 to the operators and operating equipment, so as to ventilate the operators in the device and increase the comfort of the workers' working environment. An air outlet 24 is provided on the side wall of the first partition 1 in the direction opposite to the connecting pipe 22. The air outlet 24 is connected to the outside world to balance the air pressure in the device, thereby achieving the effect of sound insulation and noise reduction, and there is no harm to the workers. The vent size is small, and the sound leakage generated meets the noise reduction requirements.

[0027] A first connecting plate 12 is provided on the top of the first partition 1, and the first connecting plate 12 is L-shaped. A first connecting shaft 311 is provided at the end of the first fixed plate 31, and the first connecting shaft 311 is rotatably connected to the first connecting plate 12. The rear end face of the first fixed plate 31 is located behind the first partition 1, thereby ensuring that the first fixed plate 31 can flip smoothly when rotating backward and will not conflict with the first partition 1.

[0028] A accommodating cavity is provided in the middle of the first fixed plate 31, and the first movable plate 32 is slidably connected to the accommodating cavity. Different sound insulation areas are required according to different construction contents. At this time, the length of the device can be changed by sliding the first sliding plate. Sound-absorbing cotton is provided at the bottom of the accommodating cavity. The first fixed plate 31 also has the function of sound insulation and noise reduction, which can prevent sound from propagating upward.

[0029] A slide groove 312 is provided on the first fixed plate 31, and the slide groove 312 runs through the top of the first fixed plate 31. The slide groove 312 does not affect the noise reduction effect of the first fixed plate 31. A slider 321 is provided on the top of the first movable plate 32, and the slider 321 is slidably connected to the slide groove 312. When the first movable plate 32 is extended or retracted, the slider 321 slides in the slide groove 312. The slide groove 312 limits the moving length of the slider 321 to prevent the first movable plate 32 from detaching from the first fixed plate 31 when sliding.

[0030] A second connecting piece 322 is provided at one end of the first movable plate 32, and the second connecting piece 322 is also L-shaped. A second connecting shaft 41 is provided at the top of the second partition 4, and the second connecting piece 322 is rotatably connected to the second connecting shaft 41. The top surface of the second partition 4 is located above the first movable plate 32, so that the second partition 4 can rotate upward smoothly.

[0031] The first movable plate 32 and the second partition plate 4 are both made of sound-insulating and noise-reducing materials.

[0032] like Figure 3 As shown, when the device is not in use, the first partition 1, the second partition 4 and the telescopic plate 3 can be stored and preserved. When storing, the first movable plate 32 is inserted into the accommodating cavity, and the second partition 4 is rotated to the top of the first fixed plate 31 with the second connecting shaft 41 as the axis. Then, the first fixed plate 31 is rotated to the rear of the first partition 1 with the first connecting shaft 311 as the axis. In this way, the device can be stored and preserved, and can be unfolded when in use.

[0033] A universal wheel 313 is disposed at the bottom of the first fixing plate 31 , and the universal wheel 313 can be placed on the ground after the device is folded, so as to facilitate the movement of the device.

[0034] The side wall plate 5 does not participate in the overall storage, but the side wall plate 5 is retractable, and the retracted side wall plate 5 can be directly placed on the first partition plate 1 after storage and moved together.

[0035] The second fixed plate 51 is provided with an accommodating cavity, and the second movable plate 52 is slidably connected to the accommodating cavity. The telescopic length of the second movable plate 52 corresponds to the telescopic length of the first telescopic plate 3 .

[0036] The side walls of the first fixed plate 31 and the side walls of the second partition plate 4 are provided with connecting bolts 6, and the second fixed plate 51 and the second movable plate 52 are provided with connecting holes. When installing the second fixed plate 51 and the second movable plate 52, the connecting bolts 6 can be passed through the connecting holes, and then the locking nuts 7 are screwed into the connecting bolts 6 to position the second fixed plate 51 and the second movable plate 52. After the installation is completed, the noise can be prevented from propagating to the outside. When storing, the second fixed plate 51 and the second movable plate 52 are removed, and the second movable plate 52 is moved into the second fixed plate, and can be placed on the first partition plate 1 after storage.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
