2. Background technology:

At present, in the noise control process of the pump room unit, the sound insulation screen is widely used as one of the main noise reduction measures. However, the sound insulation screens used at this stage have the following shortcomings: the structure is simple, and it is not convenient for the staff to inspect; the sound insulation screen cannot be removed quickly and conveniently in emergency situations and equipment maintenance; The sound screen occupies the safe passage in the pump room, which increases the safety hazard to a certain extent.

3. Contents of the invention:

The purpose of this utility model is to provide a movable sound insulation screen for the above-mentioned defects in the prior art, so as to achieve the purposes of efficient noise reduction, convenient inspection, and portability and mobility.

Its technical solution is: mainly composed of sound-absorbing panels, sound-insulating windows, base brackets and silent universal wheels, from top to bottom are sound-absorbing panels, sound-insulating windows, sound-absorbing panels, base brackets and silent universal wheels, The sound-absorbing panel and the sound-insulating window are connected through a steel frame and fixed on a base equipped with universal wheels.

The above-mentioned sound-absorbing panel is composed of perforated aluminum plate, sound-absorbing material, iron plate, and damping layer. The perforated aluminum plate is used as the inner panel of the sound insulation screen, and the iron plate is used as the outer panel. The sound-absorbing material is filled in the middle, and the damping layer is coated on the inner side of the outer panel.

The above-mentioned sound-proof window is composed of two layers of float glass with different thicknesses, sealing strips) and a frame, and the middle of the double-layer glass is an air layer, and the thickness of the air layer is ≥ 50mm.

The above-mentioned base is welded by angle steel and channel steel, and the angle steel is fixed on the sound-absorbing panel steel skeleton and channel steel, and the silent universal wheel is installed at the bottom of the channel steel.

The above-mentioned universal wheels adopt silent universal wheels, and the damping layer is an ion damping layer.

The beneficial effects of the utility model are: not only the appearance is beautiful and generous, but also it is convenient for the staff to observe the operation of the equipment, it is light and movable, and can be combined freely, it can absorb and insulate the sound more effectively, reduce the noise of the pump room, and improve the working environment and environment of the staff. The surrounding environment of the unit pump room has good economic and social benefits.

Ionic damping layer, 8, sound-absorbing material, 9, angle aluminum, 10, perforated aluminum plate; in Figure 4, 11, 4mm thick float glass, 12, 5mm thick float glass, 13, sealing strip.

5. Specific implementation methods:

Combined with the accompanying drawings 1-4, the utility model is further described: it is mainly composed of a sound-absorbing panel 1, a sound-insulating window 2, a base bracket 4 and a universal wheel 3, and from top to bottom are the sound-absorbing panel 1, the sound-insulating window Window 2, sound-absorbing panel 1, base bracket 4 and universal wheels 3, the sound-absorbing panel 1 and sound-insulating window 2 are connected through a steel frame 5 and fixed on a base equipped with universal wheels.

The steel plate 6 is used as the outer panel, and is welded on the steel frame 5, and the position of the sound insulation window is reserved before welding. The inner wall of the steel plate is coated with an ion damping layer 7 to avoid the coincidence effect. The sound-absorbing material 8 is filled in the frame, and the perforated aluminum plate 10 is used as the inner panel of the screen and riveted on the steel frame 5 . Float glass 11, 12 is installed in the reserved position, and is sealed with sealing strip 13. Weld the base 4 made of channel steel and angle steel at the bottom of the screen, and install 4 sets of silent universal wheels 3 on the base 4. Adjust the color of the sound insulation screen according to the equipment of the pump room unit and the color of the room. After the paint is dry, wrap it with angle aluminum 9.

Parameters such as the hole diameter and punching rate of the perforated aluminum plate 10, the density of the sound-absorbing material 8, and the fiber diameter are all determined according to the noise characteristics generated by the operation of the equipment, so that the resonance frequency of the sound-absorbing material is as close as possible to the noise frequency to be controlled, so as to To achieve a good sound absorption effect.

The height of the soundproof window 2 is determined according to the height of the instrument that the staff needs to observe. The two layers of glass adopt different thicknesses of 4mm and 5mm, and the air layer in the middle is greater than 50mm, so that the noise will pass through three different media continuously, and its energy will be greatly reduced after being blocked by layers.

The silent universal wheel 3 is installed on the base 4 of the sound-insulating screen, and the sound-insulating screen can be arranged between the sound source and the operating point during use, and can be placed on the wall as a sound-absorbing body when not in use. Multiple movable sound insulation screens are connected together to form a large-area sound insulation barrier or a sound insulation room. It can be quickly transferred from one unit that is stopped to another unit that is ready to start. It is very convenient to disassemble, save time and effort, and make the sound insulation screen work continuously.
