[0022] like Figure 1-4 As shown, a dust prevention device for water conservancy and hydropower equipment includes a support shell 1, which is a rectangular hollow cavity with an upper opening, and two sides of the bottom of the support shell 1 are fixedly connected to support legs 2, and the support legs 2 are symmetrically arranged. It also includes a partition 3, a cylinder 4, a mesh cover 5 and a dust suction component 6. The partition 3 is fixedly connected to the inner side wall of the support shell 1, and a recovery chamber 7 is formed between the partition 3 and the inner bottom wall of the support shell 1. A support plate 14 is provided on the upper part of the partition 3, and the support plate 14 is symmetrically arranged. The device swings through the support plate 14 It is placed on the partition 3 with a certain distance between it and the partition 3. The cylinder 4 is arranged on both sides of the upper part of the partition 3. The cylinder 4 is symmetrically arranged. The mesh cover 5 is fixedly connected to the symmetrical telescopic end of the cylinder 4. The mesh cover 5 is arranged in a rectangular shape with an opening at the bottom. The mesh cover 5 is sleeved on the upper part of the support shell 1 and slides and adjusts along the outer side wall of the support shell 1. By driving the cylinder 4 to extend and retract, the mesh cover 5 can be slid and adjusted on the upper end of the support shell 1. The dust collection component 6 is arranged inside the recovery chamber 7, which is used for the internal and external gas circulation of the support shell 1 and the filtering and recovery of dust.

[0023] like Figure 3 and Figure 4 As shown, in order to increase the air suction above the partition 3 and remove dust from the space for storing equipment above the partition 3, the dust suction component 6 includes a dust suction pipe 8, a baffle 9, an air pump 10 and a second filter 11. The dust suction pipe 8 passes through the partition 3 and is arranged inside the partition 3. The dust suction pipe 8 is arranged in a ring-shaped and uniformly spaced arrangement. The air pump 10 is fixedly connected to the bottom wall of the support shell 1. The air inlet end of the air pump 10 is connected to the recovery chamber 7. The second filter 11 is arranged on the inner bottom wall of the support shell 1. The second filter 11 is in a tubular shape with an opening at the bottom. The second filter 11 cover is arranged outside the air inlet end of the air pump 10. The baffle 9 is arranged on the bottom wall of the partition 3. The driving air Pump 10, the air pump 10 creates negative pressure in the storage chamber, absorbs the air above the partition 3 through the dust suction pipe 8, and drives the dust into the storage chamber at the same time. The baffle 9 blocks the dust, and there is a gap between the bottom of the baffle 9 and the bottom wall of the support shell 1. The diameter of the baffle 9 is larger than the diameter of the filter screen 11, so that the dust is concentrated along the baffle 9 between the baffle 9 and the filter screen 11. The filter screen 11 blocks the dust, so that the air is absorbed and discharged by the air pump 10, and the air pump 10 is prevented from sucking in dust. The bottom wall of the support shell 1 is hinged with a dust removal door 13, and the dust collected in the recovery chamber 7 can be discharged by opening the dust removal door 13.

[0024] Among them, a filter 12 is provided in the middle of the outer wall of the supporting shell 1, and the filter 12 is symmetrically arranged. When the mesh cover 5 slides up and down, the hot air generated by the equipment floats vertically upward, and the air can be inhaled through the two sides of the mesh cover 5 and the filter 12. The filtering effect of the air on both sides can be adjusted according to the height of the mesh cover 5.

[0026] When circulating air and filtering dust in the air, drive the air pump 10, the air pump 10 creates negative pressure in the storage chamber, absorbs the air above the partition 3 through the dust suction pipe 8, and drives the dust into the storage chamber at the same time, the baffle 9 blocks the dust, and there is a gap between the bottom of the baffle 9 and the inner bottom wall of the support shell 1. The diameter of the baffle 9 is larger than the diameter of the filter screen 11, so that the dust is concentrated along the baffle 9 between the baffle 9 and the filter screen 11. The filter screen 11 blocks the dust, so that the air is absorbed and discharged by the air pump 10, so as to prevent the air pump 10 from sucking in dust, and open the dust removal door 13 to discharge the dust collected in the recovery chamber 7.
