The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, and embodiment of the present utility model includes but not limited to the following example.
Embodiment
As shown in Figure 1, 2, natural inflow cooling tower acoustic hood, comprises the cover body 1 being made up of sound insulationg board, and is arranged at the waterproof rain cap 18 at the outer top of cover body; Described cover body bottom surrounding is provided with the lower ventilating opening 2 for circulation of air, and top is provided with the upper ventilating opening 3 for circulation of air; In described cover body, be provided with the sound attenuation assembly that is positioned at ventilating opening below, be positioned on the cover body inwall of sound attenuation assembly below and be also provided with the first anechoic sheet 4, be also provided with the guiding device 20 removably connecting with cover body under being positioned at sound attenuation assembly; By being provided with upper ventilating opening and lower ventilating opening, the utility model is in insulating against sound, natural wind can enter in cover body from bottom automatically, then discharge from upper ventilating opening, and the heat that cooling tower produces and gas also can be discharged cover body from upper ventilating opening due to the existence of guiding device, thereby play heat sinking function, avoided causing cooling tower normally not move owing to dispelling the heat; Simultaneously also without by other power-equipments to forcing air inlet in cover body, thereby reduced greatly energy consumption, and cost.
In order better to play the effect of noise elimination, sound insulation, described sound attenuation assembly is made up of two the second anechoic sheets 5 that are parallel to each other above, and has the gap for circulation of air between the second adjacent anechoic sheet; Described the first anechoic sheet and the second anechoic sheet are by acoustic board, and the system framework that is arranged at acoustic board outer wall surrounding and is close to acoustic board; In addition, as shown in Figure 3, described acoustic board is sandwich construction, is made up of the first color steel 6, the first glass-fiber-fabric 7, the first acoustical cotton 8, the second glass-fiber-fabric 9, the second color steel 10 that are connected successively; Wherein, on the first color steel and the second color steel, be equipped with multiple through holes, framework is in contact with the first color steel, the first glass-fiber-fabric, the first acoustical cotton, the second glass-fiber-fabric and the second color steel.When the noise in cover body is by guiding device during to cover body external diffusion, can be through sound attenuation assembly, due to the sandwich construction of acoustic board, can effectively guarantee the effect of eliminating the noise, certainly according to the needs of actual conditions, two acoustic boards can be combined into an acoustic board, thereby strengthen the effect of sound absorption, reduce the pollution of noise.
As shown in Figure 4, described sound insulationg board is sandwich construction, from outer wall to inwall, combined by the 3rd color steel 9, Sound-proof material 10, the 4th color steel 11, the 3rd glass-fiber-fabric 12, the second acoustical cotton 13, the 3rd glass-fiber-fabric 14 and multicolored steel plate 15 successively, wherein, on multicolored steel plate, be also provided with multiple through holes.By above-mentioned setting, when the first anechoic sheet and the second anechoic sheet are eliminated the noise, the second acoustical cotton on sound insulationg board can be assisted noise elimination equally, on sound panel, be provided with Sound-proof material simultaneously, thereby play the effect of sound insulation, sound insulationg board of the present utility model not only can play the effect of sound insulation, can also play the effect of sound absorption, thereby improved soundproof effect of the present utility model, and the effect of sound insulation.
In order better to realize the utility model, the prismatoid structure that described guiding device is interior sky; And top and bottom are hatch frame.And the little one side of area is connected with the blower fan mouth at cooling tower top, the one side that area is large is connected with in cover body, the heat of cooling tower and gas just can be discharged cover body faster by guiding device, avoid staying for a long time and in cover body, cause the situation that equipment cannot normally be worked to occur.
In order to prevent that when the ventilating noise-elimination, heat causes damage to the utility model, so be equipped with high-temperaure coating on the surface of the first color steel, the second color steel, multicolored steel plate and framework.
In addition, be also provided with soundproof door 19 on described cover body, this soundproof door is positioned at lower ventilating opening top.Be provided with soundproof door, can facilitate personnel to enter in cover body and overhaul.
In order better to realize ventilation effect, the longitudinal cross-section of the second anechoic sheet bottom of the present utility model is tip shape, and the longitudinal cross-section on top is circular-arc, can clearly find out the structure of the second anechoic sheet from Fig. 2.In the time that gas enters from lower ventilating opening that cover body is backward reaches the second anechoic sheet bottom, because bottom is tip shape, distance between the second adjacent anechoic sheet is just larger, gas inlet is more, easy to exhaust, and in the time that gas outreaches, the second anechoic sheet is circular-arc, gas just can, along with circular arc outer wall continues to move upward, back flow and there will not be; Thereby effectively raise the effect of ventilation.
According to above-described embodiment, just can realize well the utility model.What deserves to be explained is; under prerequisite based on said structure design; for solving same technical problem; even if some that make on the utility model are without substantial change or polishing; the essence of the technical scheme adopting is still the same with the utility model, therefore it also should be in protection domain of the present utility model.
