Problems solved by technology
If you blindly increase the sound insulation by increasing the thickness of the components, the cost performance is low, because theoretically doubling the thickness can increase the sound insulation by up to 6dB; and adding a layer of air between the two layers of visual components requires a greater increase in the sound insulation , there is a requirement for the thickness of the air layer, so that the overall thickness of the component unit is too high

Embodiment Construction
[0032] A sound insulation strengthening device for visual building components of a heat source plant, such as figure 1 and figure 2 As shown, a rectangular ring frame 2 is included, and two mutually parallel light-transmitting plates 3 are fixed inside the ring-shaped frame 2 , and a closed cavity is formed between the two light-transmitting plates 3 . The annular frame 2 is fixed in the installation hole of the building exterior wall, and the size of the outer wall of the annular frame 2 is the same as the aperture of the installation hole. After the annular frame 2 is clamped in the installation hole, the connection gap between the annular frame 2 and the inner wall of the installation hole can be filled by fixing glue, so that the annular frame 2 and the inner wall of the installation hole are fixed firmly. The top and bottom of the annular frame 2 are respectively provided with a water inlet pipe 4 and an outlet pipe 5 which communicate with the cavity. The water pump 4...

The invention discloses a sound insulation reinforcement device for a visual building component of a heat source factory. The technical scheme of the sound insulation reinforcement device is characterized by comprising an annular frame fixed in a mounting hole and two light-transmitting plates arranged in the annular frame at an interval, wherein a cavity is formed between the two light-transmitting plates, a water inlet pipe and a water outlet pipe are arranged above and below the annular frame respectively and communicated with the cavity, the other end of the water inlet pipe is connected with a cold water source, a water pump is connected to the water inlet pipe, and the other end of the water outlet pipe is connected to a circulating water way of cooling water of the heat source factory. The device has the advantages that the sound insulation performance of the visual building component is improved.
Description
technical field [0001] The invention relates to the field of sound insulation strengthening and acoustic environment improvement of visible building components of heat source plants that need to reduce noise, and in particular relates to a sound insulation strengthening device for visible building components of heat source plants. Background technique [0002] Central heating refers to the way that steam and hot water generated by centralized heat sources are supplied to a city (town) or part of the region through a pipe network to produce, heat and live in heat. Central heating is one of the infrastructures of modern cities and an important facility of urban public utilities. [0003] For central heating in cities, heat source plants are the main force, but their geographical locations are often concentrated in residential areas or mixed civil and commercial areas. The requirements for noise emission limits in these areas are relatively high; when the boilers in heat source...
