Description

Technical Field

[0001] The present invention relates to the technical field of guardrails, and in particular to a guardrail with a dustproof function and a use method thereof. Background Art

[0002] A construction site is a location where construction projects and civil engineering works are underway. These areas are often enclosed by fences, wire mesh, or walls, restricting the entry and exit of personnel, materials, machinery, and vehicles. During excavation, large amounts of dust are generated, which becomes airborne and seriously impacts the surrounding environment.

[0003] After searching, the Chinese patent application number 202220914713.9 discloses a guardrail for construction sites with a dust-proof function, including a guardrail body and a dust suppression sprayer; dust collection components are provided on both sides of the guardrail body, and an arc-shaped inclined groove is provided at the inner bottom of the guardrail body. The bottom of the guardrail body is connected to an excretion component, and a through hole is provided at one end of the top of the guardrail body; wherein, the dust suppression sprayer is arranged at the top of the guardrail body, and the bottom of the dust suppression sprayer is connected to a spraying port, and the spraying port is arranged at the inner top of the guardrail body, one end of the dust suppression sprayer is connected to a connecting hose, the other end of the connecting hose passes through the through hole, and the other end of the connecting hose is connected to a water pump, and the water pump is placed on the arc-shaped inclined groove.

[0004] The guardrail for construction sites in the above-mentioned patent has the following shortcomings: the device connects several dust collection ports on both sides of the guardrail body, and the inner ports of the dust collection ports are fixedly connected to an inclined baffle. Dust enters the guardrail body through the outer ports of the dust collection ports, and then is subjected to dust reduction through the spraying ports connected to the dust reduction sprayer on the top of the guardrail body, effectively collecting and reducing the dust around the construction site, thereby improving the dust reduction effect; in actual use, the inclined baffle guides the dust to the interior of the guardrail body, and then reduces the dust through water mist. Although there are a large number of dust collection ports on the surface of the guardrail, the overall structure is not convenient for air flow, and the dust flying in the air is not convenient for entering the interior of the guardrail body.

The dustproof guardrail according to claim 7, characterized in that: A rotating shaft bracket 1 (38) is rotatably mounted on the middle of the connecting rotating shaft 1 (37), and a bevel gear 1 (39) is fixedly mounted on the bottom end of the connecting rotating shaft 1 (37), and a bevel gear 2 (40) is meshedly connected to the outer wall of the bevel gear 1 (39).

9. The protective fence with dustproof function according to claim 8, characterized in that: A second connecting shaft (41) is fixedly mounted on one side of the second bevel gear (40), a second connecting shaft bracket (42) is rotatably connected to the middle of the second connecting shaft (41), and a third connecting sprocket (43) is fixedly mounted on one end of the second connecting shaft (41).

10. A method for using a dustproof guardrail according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1: the device is powered on; the electrostatic dust removal structure composed of the discharge electrode (21) and the dust collecting electrode (30) is connected to high voltage direct current, and the exhaust guide fan (7) is connected to the construction site circuit to extract the dust generated at the construction site; S2: dust and gas separation; the exhaust guide fan (7) guides the air entrained with dust into the electrostatic dust removal structure, the discharge electrode (21) ionizes the gas molecules, the negative ions combine with the dust particles, the dust particles are charged, move toward the dust collecting electrode (30), and are deposited on the surface of the dust collecting electrode (30), and the air leaves the guardrail body (2) through the dust filter column (23); S3: dust cleaning; starting the driving motor (15); the driving motor (15) drives the connecting sprocket 2 (27) and the connecting sprocket 3 (43) through the connecting sprocket 1 (17) and the chain transmission; the connecting sprocket 2 (27) drives the guide screw rod (26) to rotate; the connecting sprocket 3 (43) drives the connecting shaft 2 (41) to rotate; the connecting shaft 2 (41) drives the connecting shaft 1 (37) to rotate through the meshing of the bevel gear 2 (40) and the bevel gear 1 (39); the connecting shaft 1 (37) drives the transmission sprocket 2 (36) The transmission sprocket wheel (36) drives the transmission sprocket wheel (35) to rotate via the chain, and the transmission sprocket wheel (35) drives the lifting screw rod (34) to rotate. The lifting screw rod (34) drives the dust scraping lifting plate (32) to make up and down reciprocating motion via the lifting connecting tube (33), so as to scrape the dust on the surface of the dust collecting electrode (30) and make the dust fall into the dust collecting guide box (24), and then discharge the dust into the protection fence body (2) via the guide screw rod (26), the dust discharge guide pipe (28), and the dust discharge guide pipe (8).
