[0023] Please refer to Figures 1 to 5 , an air inlet sand guard 100 for a generator set. An air inlet sand guard 100 for a generator set includes a first door frame 1, a second door frame 2, a filter cotton board 3, a plurality of U-shaped plates 4 and an L-shaped frame 5. The first door frame 1 is fixed to the front side of the second door frame 2 along the first direction X. The filter cotton board 3 is arranged inside the second door frame 2. The plurality of U-shaped plates 4 are divided into two rows, front and back, in the first direction X and are respectively vertically fixed inside the frame of the first door frame 1. The plurality of U-shaped plates 4 are arranged in a staggered manner front and back in sequence along the second direction Y. The first direction X is perpendicular to the second direction Y. Among them, every two adjacent U-shaped plates 4 are buckled with each other and do not contact, forming a circuitous and turning air inlet channel. Each air inlet channel intakes air along the first direction X between two adjacent U-shaped plates 4 in the front row. After being blocked and guided twice by the bottom plates of the two U-shaped plates 4 that are staggered front and back, most of the sand grains are blocked and fall, and the air then continues to enter the second door frame 2 along the first direction X between two adjacent U-shaped plates 4 in the back row and enters the interior of the generator set after being filtered by the filter cotton board 3. Figure 4 The direction of the solid arrow in [Figure] is the air inlet path. The L-shaped frame 5 is fixed to the lower part of the first door frame 1 and is used to support and fix the bottoms of the plurality of U-shaped plates 4. A plurality of sand discharge holes 51 are provided at the bottom of the L-shaped frame 5. A downward slope 11 is provided between the bottom of the L-shaped frame 5 and the bottom frame of the first door frame 1. The slope 11 is located below the plurality of sand discharge holes 51 and is communicated with the plurality of sand discharge holes 51 for discharging sand grains downward.
[0024] Optionally, the plurality of sand discharge holes 51 are respectively close to the bottom plates of the plurality of U-shaped plates 4. Since the position where the air inlet is blocked and redirected is exactly at the bottom plate of each U-shaped plate, setting the sand discharge holes here has a better sand discharge effect.
[0025] Preferably, two sand discharge holes 51 are provided close to the bottom plate of each U-shaped plate 4, and the two sand discharge holes 51 are respectively close to one side plate of the U-shaped plate 4. Since the air inlet will be diverted along both sides of the U-shaped plate, such a setting has a better sand discharge effect.
[0026] Optionally, the distance between any two adjacent U-shaped plates 4 in the front row is equal, and the distance between any two adjacent U-shaped plates 4 in the back row is equal. In this way, the air inlet is more balanced.
[0027] Optionally, the distance between any two adjacent U-shaped plates 4 in the front row is equal to the distance between any two adjacent U-shaped plates 4 in the rear row. This setting makes the air intake more balanced.
[0028] Optionally, the width of the slope 11 along the second direction Y is equal to the inner frame width of the first door frame 1 along the second direction Y. This setting provides a better sand discharge effect.
[0029] Optionally, the air intake sand-proof door 100 further includes a pressure strip 6 extending along the second direction Y. The pressure strip 6 is fixed to the upper part of the first door frame 1 and is used to fix the upper parts of the plurality of U-shaped plates 4 inside the first door frame 1. This facilitates the fixation of the U-shaped plates.
[0030] Optionally, the plurality of U-shaped plates 4 are detachably fixed inside the first door frame 1. This facilitates the disassembly, maintenance, and cleaning of the U-shaped plates.
[0031] Optionally, the side part of the second door frame 2 is a detachable pressing plate 21. This setting facilitates the replacement of the filter cotton board.
[0032] An air intake sand-proof door for a generator set of the present utility model can not only prevent sand and dust during the air intake of the generator set, but also effectively ensure the air intake required during power generation. At the same time, it can effectively prevent the blockage of wind and sand, greatly increasing the service life of the filter cotton board.
