[0029] Such as Figures 1 to 6As shown in the figure, the ventilation and sound insulation structure of the control room of the present utility model includes: a control room body 1, an air inlet window and an air outlet window are formed on both sides of the control room body 1, and a first housing 2 and a second housing 3 for covering the air inlet window and the air outlet window are respectively arranged on both sides of the control room body 1. An air inlet opening 21 is formed at the bottom end of the first housing 2, and an air outlet opening 31 is formed at the bottom end of the second housing 3; a first noise reduction component 4 and a second noise reduction component 5, the first noise reduction component 4 is arranged in the first housing 2 to reduce the noise generated by the airflow sucked into the control room body 1, and the second noise reduction component 5 is arranged in the second housing 3 to reduce the noise generated by the airflow discharged from the control room body 1.

[0030] See Figure 1 、 Figure 2 , at the lower part of the control room body 1, there are an air inlet window and an air outlet window, and the air inlet window and the air outlet window can be arranged opposite or adjacent to each other on the control room body 1.

[0031] See Figure 4 、 Figure 5 , both the first housing 2 and the second housing 3 are in the shape of a square housing with two open sides. One of the openings of the first housing 2 covers the air inlet window of the control room body 1, and the other opening is arranged downward to form the air inlet opening 21. One of the openings of the second housing 3 covers the air outlet window of the control room body 1, and the other opening is arranged downward to form the air outlet opening 31. A ventilation device is arranged in the control room body 1, and the ventilation device can be a cooling fan or a blower. Through the ventilation device, the external air flow can be drawn into the control room body 1 through the air inlet opening 21 and the air inlet window to dissipate heat from the noise generating equipment inside the control room body 1. At the same time, the air flow inside the control room body 1 can be discharged from the control room body 1 through the air outlet window and the air outlet opening 31 to achieve the air flow effect.

[0032] See Figures 1 to 6 , the first noise reduction component 4 is arranged in the first housing 2, and the second noise reduction component 5 is arranged in the second housing 3. When the ventilation device works, certain noise will be generated when the air flow passes through the first housing 2. The first noise reduction component 4 can weaken the noise generated by the air flow. Correspondingly, when the air flow passes through the second housing 3, noise will also be generated, and the second noise reduction component 5 can weaken the noise in the second housing 3. In addition, when the working equipment in the control room body 1 generates noise, the noise will be conducted to the inside of the first housing 2 through the air inlet window and to the inside of the second housing 3 through the air outlet window. The first noise reduction component 4 and the second noise reduction component 5 can further weaken the noise generated inside the control room body 1, realize the control of the noise inside the control room body 1, and improve the use effect of this application.

[0033] In one or more embodiments, the air inlet opening 21 of the first housing 2 is located above the bottom end of the control room body 1, and the air outlet opening 31 of the second housing 3 is located above the bottom end of the control room body 1.

[0034] See Figure 1 , Figure 2 , the bottom ends of the first housing 2 and the second housing 3 are located above the bottom end of the control room body 1. With this arrangement, the smoothness of the air intake through the air inlet opening 21 and the smoothness of the air exhaust through the air outlet opening 31 can be ensured, and the heat dissipation effect on the working equipment in the control room body 1 can be guaranteed.

[0035] In one or more embodiments, the first noise reduction component 4 includes sound-absorbing cotton and a perforated plate 41. Among them, the sound-absorbing cotton is located between the inner wall of the first housing 2 and the perforated plate 41.

[0036] See Figure 3 , Figure 4 , the sound-absorbing cotton is located between the inner wall of the first housing 2 and the perforated plate 41. The perforation rate of the perforated plate 41 is 19% - 25%. The perforated plate 41 is one of galvanized steel plate, color steel plate, carbon steel plate or aluminum alloy plate, and has a certain supporting and protecting effect. When noise enters the first housing 2, the noise can pass through the perforations formed on the perforated plate 41 and be absorbed and dissipated by the sound-absorbing cotton. In a specific embodiment, the material of the sound-absorbing cotton is one or more of glass wool, rock wool, polyester fiber sound-absorbing cotton, wood wool board and honeycomb metamaterial.

[0037] In one or more embodiments, the second noise reduction component 5 includes at least one group of sound insulation modules arranged along the width direction of the control room body 1. The sound insulation module includes a support plate 51 and a porous sound-absorbing member disposed inside the support plate 51; the top end of the sound insulation module does not contact the inner top surface of the second housing 3; the cross-sectional area of the top end of the support plate 51 gradually decreases to form a flow disturbance structure 52.

[0038] See Figure 2 , Figure 5 , Figure 6 , multiple groups of sound insulation modules are arranged in the second housing 3 along the width direction of the control room body 1. The sound insulation module includes a support plate 51 and a porous sound-absorbing member disposed inside the sound insulation plate. The support plate 51 has a square structure. The top end of the support plate 51 forms a flow disturbance structure 52 with a gradually decreasing cross-sectional area, and the top end of the support plate 51 does not extend to contact the inner top surface of the second housing 3. With this arrangement, the air flow flowing into the second housing 3 through the air outlet window will first pass through the flow disturbance structure 52. The downward flowing air flow is guided and split by the flow disturbance structure 52, and the noise generated by the air flow can be reduced. At the same time, the noise generated by the air flow and the noise conducted from the control room body 1 are absorbed and dissipated by the porous sound-absorbing member inside the support plate 51, which can effectively improve the noise reduction effect of the present application.

The configuration of the sound-absorbing holes can facilitate the absorption of the noise passing through the flow disturbance structure by the porous sound-absorbing member; at the same time, configuring the flow disturbance structure into a smooth shape can reduce the resistance of the air flow passing through the flow disturbance structure 52 and accelerate the air flow inside the control room body 1 and inside the second housing 3.

[0041] In other possible embodiments, the support plate 51 can be configured as a porous plate as a whole, so that the noise passing through the porous plate can be further absorbed by the porous sound-absorbing member.

[0042] In other possible embodiments, the top end of the support plate 51 extends to the connection with the inner top surface of the second housing 3, and the support plate 51 forms a flow disturbance structure 52 with a gradually decreasing cross-sectional area on the side facing the air outlet window of the controller body; through this configuration, the air flow entering the second housing 3 can also be shunted, ensuring the flow efficiency of the air flow.

[0043] In one or more embodiments, a flow guiding structure 6 is formed on the inner wall of the second housing 3 opposite to the air outlet window. Refer to Figure 2 、 Figure 6 , through this configuration, the air flow entering the second housing 3 through the air outlet window can be guided by the flow guiding structure 6 and smoothly flow towards a plurality of sound insulation modules, further accelerating the flow rate of the air flow inside the second housing 3.

[0044] In one or more embodiments, filter plates 7 are arranged at both the air inlet window and the air outlet window of the control room body 1. Refer to Figure 1 、 Figure 2 , through the filtration of impurities by the metal filter plate 7, the working environment inside the control room body 1 can be ensured.

[0045] In other possible embodiments, the two filter plates 7 can be respectively arranged at the air inlet opening 21 and the air outlet opening 31.
