Technical Field

[0001] The utility model relates to an environmentally friendly noise reduction device, in particular to an environmentally friendly noise reduction device for construction management applied to the field of construction. Background Art

[0002] Building construction refers to production activities during the implementation phase of engineering construction. It is the construction process of various types of buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. It includes foundation engineering construction, main structure construction, roofing engineering construction and decoration engineering construction. The place where the construction work takes place is called a construction site, and a large amount of noise will be generated during the construction process.

[0003] The specification of Chinese patent CN216380060U discloses an environmentally friendly noise reduction device for construction management. During the installation process of the environmentally friendly noise reduction device for construction management, the noise reduction plate can be plugged into the sliding grooves on the two fixed plates. During the plugging process, the plug-in column slides on the inner wall of the strip groove. When the plug-in column corresponds to the plug-in groove, the plug-in column is plugged into the plug-in groove under the action of a tightening spring, thereby realizing the rapid installation of the noise reduction device, effectively improving the work efficiency, and the disassembly is also very convenient, providing convenience for the disassembly personnel.

[0004] However, in actual application, the use of noise reduction panels alone can only block some low-frequency noise. In addition to low-frequency noise, there will also be some high-frequency noises on the construction site, such as electric saw cutting sounds, tweeters, machine knocking and collisions. The sound insulation effect of these high-frequency noises is poor. Hearing high-frequency noises for a long time will cause harm to surrounding residents, such as hearing loss and tinnitus, thereby affecting the health of surrounding users. Utility Model Content

[0007] In the above-mentioned environmentally friendly noise reduction device for construction management, low-frequency and high-frequency noises can be effectively blocked at the same time, thereby improving the sound insulation effect of the device and effectively preventing noise from causing harm to surrounding users.

[0008] As a further improvement of the present application, two accommodating grooves are provided at the outer end of the fixed column, a sliding rod is fixedly connected to the accommodating groove at the left end, springs and clamping plates are sequentially mounted on the corresponding ends of the two sliding rods, an adjusting plate is fixedly connected to the front end of the clamping plate, and two rectangular holes are also drilled at the front end of the fixed column on the left, which are respectively connected to the accommodating grooves, and the adjusting plate movably passes through the rectangular holes.

[0009] As a further improvement of the present application, the left side of the clamping plate is a trapezoid with rounded corners, and a trapezoidal limiting groove is provided on the side away from the inner wall of the accommodating groove at the right end.

[0010] As a further improvement of the present application, the two ends of the spring are fixedly connected to the clamping plate and the inner wall of the accommodating groove respectively, and the limiting groove matches the left end of the clamping plate.

[0012] As another improved supplement of the present application, the solar panel is electrically connected to the rechargeable battery, and the rechargeable battery is electrically connected to the lighting lamp.

[0013] To sum up, in actual application, low-frequency noise can be effectively absorbed and blocked by sponge sound-absorbing balls and aluminum honeycomb sound-absorbing panels, the vacuum cavity can reduce some high-frequency noise pollution, and PVB laminated glass can perform secondary noise reduction on low-frequency noise and high-frequency noise, thereby weakening the propagation of construction site noise and attenuating it, thereby effectively avoiding the harm of construction site noise to surrounding residents and facilitating the use of staff.
