[0025] A dry coal shed is an open structure for storing coal. Usually, multiple support piles arranged at intervals provide support for the shed roof to prevent coal from being directly exposed to the natural environment. Multiple inlets are formed between the multiple support piles to meet the ventilation requirements of the dry coal shed. However, during the ventilation process of the dry coal shed, due to the action of wind, the coal dust in the dry coal shed is easily diffused with the wind, resulting in pollution to the surrounding environment.
[0026] The present utility model provides a ventilation and dust suppression device for a dry coal shed, which includes a support beam 10 and a dust baffle 20. The support beam 10 is provided at each inlet 51, and both ends of the support beam 10 are respectively connected to two corresponding support piles 50; a dust baffle 20 is provided on the side of the support beam 10 facing the inside of the dry coal shed. The dust baffle 20 includes a fixed section 21 and two movable sections 22. The fixed section 21 is fixed to the support beam 10, and the two movable sections 22 are respectively connected to both sides of the fixed section 21 and are arranged close to the two support piles 50. Each movable section 22 can rotate relative to the fixed section 21 between an open position and a closed position; when the wind outside the dry coal shed blows towards the inlet 51, it can push the movable section 22 to rotate from the closed position to the open position, so that an air inlet passage 23 communicating with the inlet 51 is formed between the movable section 22 and the support beam 10. When the wind inside the dry coal shed blows towards the inlet 51, it can reversely push the movable section 22 to rotate from the open position to the closed position, so that the movable section 22 abuts against the support beam 10 to close the air inlet passage 23, so as to block the inlet 51 through the dust baffle 20.
[0027] Please refer to Figure 1 and Figure 2 , Figure 1 and Figure 2 The front side of the support beam 10 in Figure 1 and Figure 2 is the outside of the dry coal shed, Figure 1 and Figure 2 the back side of the support beam 10 in
[0028] The ventilation and dust suppression device for the dry coal shed proposed by the present utility model sets a support beam 10 at the inlet 51 of the dry coal shed, installs a dust baffle 20 on the support beam 10, connects the two movable segments 22 of the dust baffle 20 to both ends of the fixed segment 21 respectively, so that both movable segments 22 can rotate relative to the fixed segment 21 between the open position and the closed position. The movable segment 22 can be pushed by the wind outside the dry coal shed to rotate to the open position to open the air inlet channel 23, allowing the wind outside the dry coal shed to enter the dry coal shed through the air inlet channel 23 to realize the ventilation in the dry coal shed. The movable segment 22 can be pushed by the wind inside the dry coal shed to rotate to the closed position to close the air inlet channel 23, preventing the coal dust in the dry coal shed from diffusing outside the dry coal shed and avoiding the pollution of the surrounding environment by the coal dust. The dust baffle 20 can realize the opening and closing of the air inlet channel 23 according to the change of the wind direction inside and outside the dry coal shed, so as to realize the automatic opening and closing of the dust baffle 20 without manual intervention, effectively improving the convenience of the opening and closing operation of the inlet 51 of the dry coal shed, realizing the ventilation requirement of the dry coal shed while avoiding the diffusion of coal dust in the dry coal shed and protecting the surrounding environment from being polluted by coal dust.
[0029] In one embodiment, the dust baffle 20 includes a plurality of folding plates connected in sequence along the extending direction of the dust baffle 20. Among them, the fixed segment 21 includes several folding plates, each movable segment 22 includes one folding plate, and the folding plates of the fixed segment 21 are fixed to the support beam 10, and the folding plates of the two movable segments 22 are flexibly connected to the folding plates on both sides of the fixed segment 21 respectively.
[0030] It can be explained that the fixed segment 21 of the dust baffle 20 is composed of several folding plates and fixed to the support beam 10, while the two movable segments 22 are each composed of one folding plate and flexibly connected to the folding plates of the fixed segment 21, realizing the automatic opening and closing of the dust baffle 20 according to the change of the wind direction inside and outside the dry coal shed, effectively controlling the diffusion of coal dust, and at the same time maintaining the ventilation requirement inside the dry coal shed. The structure design is simple and easy to maintain.
[0031] In one embodiment, each folding plate includes two folding wings 241, the two folding wings 241 are connected to each other to form a crease 242 of the folding plate, and the crease 242 is bent towards the inside of the dry coal shed; in the folding plate of the movable segment 22, one of the folding wings 241 is flexibly connected to the folding plate of the fixed segment 21, and the other folding wing 241 can form an air inlet channel 23 with the support beam 10 when in the open position and can abut against the support beam 10 when in the closed position.
[0032] Further, one end of each folding fin 241 is close to the support beam 10 and the other end is away from the support beam 10. In the same folding plate, the ends of two folding fins 241 away from the support beam 10 are connected to each other to form a crease 242, causing the middle part of the folding plate to bend towards the inside of the dry coal shed. In the folding plate located in the movable section 22, one end of a folding fin 241 away from the crease 242 is flexibly connected to the folding plate of the fixed section 21, and the other end of the folding fin 241 away from the crease 242 can abut against the support beam 10 when in the closed position. The middle part of the folding plate bends towards the inside of the dry coal shed, making the folding plate more vulnerable to the wind outside the dry coal shed, facilitating ventilation inside the dry coal shed, and enabling the folding plate to abut more closely against the support beam 10 under the push of the wind inside the dry coal shed, preventing the diffusion of coal dust inside the dry coal shed.
[0033] In one embodiment, the dust suppression device further includes a support structure which is supported on the side of the fixed section 21 facing the inside of the dry coal shed.

The support structure and the support beam 10 jointly fix the fixed section 21, which can prevent the fixed section 21 from shaking under the push of the wind and effectively enhance the stability of the dust baffle 20.
[0035] In one embodiment, the support structure includes a support column 31 and a clamp 32. The clamp 32 is sleeved outside the support column 31 and is connected to the side of the folding plate of the fixed section 21 facing the inside of the dry coal shed.
[0036] It should be noted that the clamp 32 is sleeved outside the support column 31 and is connected to the folding plate of the fixed section 21, providing a stronger fixing effect to ensure that the dust baffle 20 remains stable under the action of the wind. The design of the clamp 32 facilitates the quick disassembly and replacement of the support structure, is convenient for the maintenance and repair of the support structure, and can adapt to support columns 31 of different sizes. The structure is simple and the setting is flexible. In one embodiment, the support beam 10 is horizontally arranged, the support column 31 is vertically arranged, the support structure includes a plurality of clamps 32, and the plurality of clamps 32 are arranged at intervals along the extending direction of the support column 31 and are respectively connected to different positions of the fixed section 21 in the vertical direction to provide more stable support for the fixed section 21.
[0037] In one embodiment, the clamp 32 is U-shaped. The middle part of the clamp 32 is sleeved outside the support column 31, and the two ends of the clamp 32 are respectively connected to the creases 242 of any two adjacent folding plates. Further, the clamp 32 is sleeved outside the support column 31, and the two ends of the clamp 32 are respectively connected to the creases 242 of two adjacent folding plates, enabling the support structure to provide support for two folding plates at the same time, which helps to evenly distribute the supporting force and further improves the supporting force of the support structure on the dust baffle 20.
[0038] In one embodiment, the dust suppression device further includes a plurality of reinforcing bars 40. Each reinforcing bar 40 is located on the side of the dust baffle 20 facing the inside of the dry coal shed, and each reinforcing bar 40 abuts against the dust baffle 20 to tightly press the dust baffle 20 against the support beam 10.
[0039] It can be understood that each reinforcing bar 40 is vertically arranged, and a plurality of reinforcing bars 40 are all arranged at the connection of two adjacent folding plates, so that the reinforcing bars 40 press the dust baffle 20 tightly against the support beam 10 from the side of the dust baffle 20 facing the inside of the dry coal shed, effectively increasing the rigidity of the dust baffle 20 and preventing the dust baffle 20 from deforming under the action of wind, which helps to maintain the structural stability of the dust baffle 20.
[0040] In one embodiment, a reinforcing bar 40 is provided at the connection of the fixed section 21 and each movable section 22.
[0041] Furthermore, a reinforcing bar 40 is provided at the connection of the folding plate of the fixed section 21 and the folding plate of the movable section 22, so that the reinforcing bar 40 significantly improves the structural strength of the connection between the movable section 22 and the fixed section 21, reduces the damage of the connection caused by the frequent opening and closing of the movable section 22, and effectively improves the service life of the dust baffle 20.
[0042] In one embodiment, the fixed section 21 is fixed to the support beam 10 by steel bars 33. It can be understood that the side of the fixed section 21 facing the outside of the dry coal shed is fixedly connected to the support beam 10 by steel bars 33, ensuring the stable connection between the fixed section 21 and the support beam 10, not easy to loosen, and facilitating installation.
