DETAILED DESCRIPTION

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods, but the present invention is not limited to the following embodiments.

[0022] Embodiment 1:

[0023] See attached Figures 1-2 A rainproof ventilation hood includes an air guide plate base 101; a vent is provided in the middle of the air guide plate base 101; a plurality of air guide plates are provided on the vent; the plurality of air guide plates are staggered from bottom to top along the air guide plate base 101, and the area gradually decreases; the plurality of air guide plates completely cover the vent in vertical projection. It can be seen from the above structure that the air deflector base 101 is connected to the top of the skid-mounted equipment in various connection modes, either detachably or fixedly. The air deflector base 101 is a rectangular structure with a vent in the middle. The vent area can be as large as possible to ensure sufficient ventilation and further ensure rain protection. A number of air deflectors are arranged on the vent. Each air deflector has a similar structure to the air deflector base 101 and is rectangular. A number of air deflectors are arranged in sequence from bottom to top at a certain height, and the area gradually decreases to form a stepped shape. The air deflectors between the air deflector base 101 and the uppermost air deflector are hollow in the middle, and the uppermost air deflector is hole-free. The projection of several air guide plates from top to bottom can cover the entire vent, that is, the outermost dimension of the upper air guide plate is slightly larger than the innermost dimension of the adjacent lower air guide plate, and the outermost dimension of the lower air guide plate is also slightly larger than the innermost dimension of the air guide plate base 101, which can prevent vertically falling rainwater from directly passing through the vent into the skid-mounted equipment, causing damage to the equipment. Further, in order to achieve better ventilation effect and rainwater collection, the inner side of the air guide plate base 101 and the hollow air guide plate in the middle are bent downward to form a certain angle with the horizontal plane, but not more than 90°, and a water trough is formed at the end near the center of the vent to collect the remaining rainwater. The air guide plate bent at a certain angle can better achieve ventilation, and the water trough on the air guide plate can temporarily store rainwater to prevent rainwater from passing through the air guide plate into the skid-mounted equipment. The utility model provides a rainproof ventilation cover, which can protect the highly integrated hydrogenation skid-mounted equipment from rain while also playing a ventilation role.

[0024] Embodiment 2:

[0025] See attached Figures 1-2 On the basis of the first embodiment, the plurality of air guide plates include a first air guide plate 102, a second air guide plate 103, a third air guide plate 104, a fourth air guide plate 105 and a fifth air guide plate 106; the first air guide plate 102, the second air guide plate 103, the third air guide plate 104 and the fourth air guide plate 105 are hollow in the middle; the fifth air guide plate 106 is a non-porous plate. It can be seen from the above structure that the number and size of the air guide plates can be appropriately adjusted as needed to meet different design sizes or ventilation volume sizes. In the present embodiment, five wind guide plates are arranged, which are, from bottom to top, the first wind guide plate 102, the second wind guide plate 103, the third wind guide plate 104, the fourth wind guide plate 105 and the fifth wind guide plate 106. The fifth wind guide plate 106 is located at the topmost layer to ensure its rainproof effect. It is arranged as a closed wind guide plate without holes. The first, second, third and fourth wind guide plates 105 located between the wind guide plate base 101 and the fifth wind guide plate 106 are all arranged as hollow structures to ensure sufficient ventilation area.

[0026] The inner sides of the air guide plate base 101, the first air guide plate 102, the second air guide plate 103, the third air guide plate 104 and the fourth air guide plate 105 are bent downward to form an angle of 45° with the horizontal plane, and a "U"-shaped water collecting trough 203 is formed on one side close to the center of the vent. It can be seen from the above structure that in order to ensure a certain ventilation effect and prevent rainwater from entering the skid-mounted equipment through the air guide plate, the air guide plate base 101, the first air guide plate 102, the second air guide plate 103, the third air guide plate 104 and the fourth air guide plate 105 are arranged to bend downward on the side close to the center of the vent to form an angle of 45° with the horizontal plane. The exhaust design in the 45° direction has a larger opening size, a larger exhaust volume, and a more compact height size. At the same time, a "U"-shaped water collecting trough 203 is formed on the side close to the center of the vent of the air guide plate base 101, the first air guide plate 102, the second air guide plate 103, the third air guide plate 104 and the fourth air guide plate 105 to collect rainwater, thereby further preventing rainwater from directly flowing into the skid-mounted equipment through the air guide plate.

[0027] Embodiment three:

[0028] See attached Figures 1-2On the basis of the second embodiment, the size of the fifth air guide plate 106 is larger than the inner size of the fourth air guide plate 105; the outer size of the fourth air guide plate 105 is larger than the inner size of the third air guide plate 104; the outer size of the third air guide plate 104 is larger than the inner size of the second air guide plate 103; the outer size of the second air guide plate 103 is larger than the inner size of the first air guide plate 102; the outer size of the first air guide plate 102 is larger than the inner size of the air guide base plate. It can be seen from the above structure that, among the two adjacent layers of wind deflectors arranged from top to bottom, the outer dimensions of the wind deflectors of the upper layer are slightly larger than the inner dimensions of the wind deflectors of the lower layer, which can be expressed as the outermost side of the projection of the upper wind deflector in the vertical direction encloses the projection of the lower wind deflector in the vertical direction, wherein the outer dimensions refer to the dimensions of the outer contour of the wind deflector away from the center of the vent, and the inner dimensions refer to the dimensions of the inner contour of the wind deflector close to the center of the vent, and the inner dimensions of the wind deflector base 101 are also slightly smaller than the outer dimensions of the first wind deflector 102. This structural setting reduces the direct entry of rainwater through the vent into the skid-mounted equipment to a certain extent, and at the same time, cooperates with the wind deflector and the water collecting trough 203 on the wind deflector base 101 to further prevent the infiltration of rainwater.

[0029] The water collecting grooves 203 on the air guide plate base 101, the first air guide plate 102, the second air guide plate 103, the third air guide plate 104 and the fourth air guide plate 105 are all provided with a plurality of drain ports 202, which are evenly arranged on the water collecting grooves 203. As can be seen from the above structure, the water collecting grooves 203 are distributed on the first, second, third and fourth air guide plates 105 and the air guide plate base 101, and drain ports 202 are provided at corresponding positions on two adjacent water collecting grooves 203. Preferably, one drain port 202 is provided on the wide side of the rectangular air guide plate base 101 and the first, second, third and fourth air guide plates 105, and two water ports are provided on the long side, which are evenly arranged on the long side. The drain ports 202 corresponding to each layer can be connected into a straight line, and the water on the upper water collecting groove 203 flows out to the lower water collecting groove 203 through the drain ports 202 in sequence for drainage.

[0030] The air guide plate base 101 is provided with a drainage groove 201; one end of the drainage groove 201 is opened and arranged on the outside of the air guide plate base 101, and the other end is connected to the corresponding drain ports 202 on the air guide plate base 101, the first air guide plate 102, the second air guide plate 103, the third air guide plate 104 and the fourth air guide plate 105 in sequence. It can be seen from the above structure that the drainage groove 201 further helps to drain the rainwater on the water collecting groove 203. One end of the drainage groove 201 is arranged on the outside of the wind guide plate base 101, and the other end is connected to the drain port 202 on the water collecting groove 203 on the wind guide plate base 101, the first wind guide plate 102, the second wind guide plate 103, the third wind guide plate 104 and the fourth wind guide plate 105 in sequence. The number of drainage grooves 201 corresponds to the number of drain ports 202 on each layer of water collecting groove 203, forming six drainage grooves 201, which help the rainwater on each water collecting groove 203 to flow out from the outside of the wind guide plate base 101.

[0031] The height differences among the first air guide plate 102, the second air guide plate 103, the third air guide plate 104, the fourth air guide plate 105 and the fifth air guide plate 106 are consistent. As can be seen from the above structure, the height differences among the several air guide plates are consistent, forming a structure with consistent height difference, which is conducive to the exhaust device 601 exhausting air through the exhaust ports between the air guide plates, and the ventilation effect is better.

[0032] An inter-board support plate 401 is provided between the air guide plate base 101, the first air guide plate 102, the second air guide plate 103, the third air guide plate 104, the fourth air guide plate 105 and the fifth air guide plate 106. As can be seen from the above structure, the connection between the first air guide plate 102, the second air guide plate 103, the third air guide plate 104, the fourth air guide plate 105 and the fifth air guide plate 106 and the air guide plate base 101 is ensured to be stable, and the inter-board support plate 401 is provided between each air guide plate and between the first air guide plate 102 and the air guide plate base 101, so as to strengthen the structural strength of each air guide plate and make the work more stable.

[0033] Embodiment 4:

[0034] See attached Figures 1-2 On the basis of the third embodiment, the outer periphery of the air deflector base 101 is turned outward and provided with a mounting hole 301. As can be seen from the above structure, the air deflector base 101 can be connected to the skid-mounted equipment through the mounting hole 301, and the installation is simple.

[0035] A plurality of lifting ears 501 are evenly arranged on the upper side of the air guide plate base 101. As can be seen from the above structure, the installation position of the utility model is generally located at a high place, and the installation is more convenient through the arrangement of the lifting ears 501.
