Description

TECHNICAL FIELD

[0001] The utility model relates to load box technical field, concretely relates to a rain and snow prevention wind scooper for load top. BACKGROUND

[0002] The load box has a resistance module, and the resistance module generates a large amount of heat during operation. In order to ensure normal use of the load, a cooling fan is arranged inside the load box, an air inlet is arranged on the side of the load box, and an air outlet for heat dissipation is arranged on the top of the load box. The cooling fan forcibly cools the heat and quickly discharges the heat from the air outlet, so that the heat dissipation purpose is achieved. Because the load box is used outdoors, the air outlet is generally provided with a wind scooper to prevent rainwater from flowing back into the load box. The wind scooper also has the function of guiding the direction of the wind, so that the hot air is blown in a certain direction. With the development of electronic power technology, the use requirements for the load are increasing, and some load use occasions require that the load can be used in rainy days. Because the opening of the traditional load wind scooper is directly upward, rainwater will directly enter the load, which cannot meet the use requirements.

[0003] Later, the applicant developed a load air-cooled wind guide device disclosed in Chinese patent document No. CN114286587A. The load air-cooled wind guide device comprises a cylindrical cover body and a fan arranged below the cover body. The air inlet at the bottom of the cover body is connected to the fan downward, and the air outlet at the top of the cover body is directly connected to the outside upward. The inside of the cover body is provided with a plurality of partition plates arranged transversely. An upper and lower flow passage is formed between each two adjacent partition plates. The lower end of the partition plate is provided with a water collecting groove, and the water collecting groove is connected to the outside of the cover body. The partition plate is in an S shape, so that the upper end of the flow passage is aligned with the side wall of the partition plate downward, so that the outside rainwater enters the air outlet and is guided along the side wall of the partition plate to the water collecting groove. By arranging the partition plate, the vertically falling rainwater is guided to flow along the side wall of the partition plate, and then flows into the water collecting groove for discharge, so that the rainwater does not fall into the fan or the load below.

[0004] The partition plate of the above-mentioned existing wind guide device is too long, although it blocks the rainwater, but the hot air in the box needs to pass through a long flow passage, and there is still room for improvement in terms of wind resistance. SUMMARY

[0005] In view of all or part of the above technical problems existing in the prior art, the utility model provides a rain and snow prevention wind scooper for load top.

[0008] Each baffle comprises an inlet section, a flow-through section and a drainage section from top to bottom, the inlet section and the flow-through section are arranged to be inclined to the same side relative to the longitudinal direction, and the inclination angle of the inlet section is larger than that of the flow-through section; the flow-through section and the drainage section enclose a V-shaped guide groove with an opening upward; the upper end of the inlet section is located above the V-shaped guide groove of the transversely adjacent baffle; the two ends of the V-shaped guide groove penetrate out of the support frame;

[0009] The flow-through sections of the upper and lower baffles are arranged in parallel and leave a flow passage between each other, and the inlet section of the lower baffle is located beside the flow-through section of the upper baffle on the side away from the V-shaped guide groove.

[0010] As a further optional solution, the two ends of the V-shaped guide groove penetrate through the opposite two side walls of the support frame.

Figures 1 to 5 As shown, the support frame 1 is surrounded on all sides and open at the top and bottom. The four sides of the support frame 1 are square in shape. The bottom of the support frame 1 is provided with a mounting flange 11, which facilitates the overall fixing to the air outlet at the top of the load.

[0032] The support frame 1 is equipped with a baffle assembly, which includes multiple air guide plates 2 arranged in two rows, with each row of air guide plates 2 spaced laterally. Each air guide plate 2 is a sheet metal integral bending structure.

[0033] Each baffle 2 comprises from top to bottom an inlet section 21, a flow-through section 22 and a drainage section 23, the inlet section 21 and the flow-through section 22 are arranged obliquely to the same side relative to the longitudinal direction, and the inclination angle of the inlet section 21 is larger than that of the flow-through section 22, and the length of the flow-through section 22 is larger than that of the inlet section 21 and the drainage section 23. The flow-through section 22 and the drainage section 23 enclose a V-shaped guide groove 26 with an opening facing upward, and the two ends of the V-shaped guide groove 26 penetrate out of the support frame, facilitating the drainage of rainwater out of the support frame 1. Since the load discharges hot air, even if there is snow on the baffle 2, it can be melted. The upper end of the inlet section 21 is located above the V-shaped guide groove 26 of the transversely adjacent baffle 2, so as to prevent rainwater from falling into the load box. The flow-through sections 22 of the upper and lower baffles 2 are arranged parallel to each other and leave a flow passage 24 therebetween, and the inlet section 21 of the lower baffle 2 is located beside the flow-through section 22 of the upper baffle 2 on the side away from the V-shaped guide groove 26.

[0034] In the embodiment, the two ends of the V-shaped guide groove 26 penetrate through the opposite two side walls of the support frame. Actually, the baffle 2 and the support frame 1 are clamped with each other to realize installation. Even if the baffle 2 and the support frame 1 are connected loosely, that is, a gap is left between the V-shaped guide groove 26 and the mounting hole of the support frame 1, the V-shaped guide groove 26 can vibrate to some extent, and under the action of hot air blowing, the snow on it can be shaken and melted.

[0035] Actually, the baffle 2 is a double-layer structure, which comprises a metal plate layer and a heat insulation layer arranged in layers.

[0036] Another embodiment is described with reference to Figure 5 As shown, the flow-through section 22 is punched and formed with a plurality of drainage holes 25 penetrating through the V-shaped guide groove 26 in the direction away from the V-shaped guide groove 26, which is similar to a convex structure, and the water droplets splashed on the back of the flow-through section 22 are guided to the V-shaped guide groove 26. The plurality of drainage holes 25 are distributed in the transverse direction on the corresponding baffle 2.
