Description

Technical Field

[0001] The utility model belongs to the technical field of sand prevention in construction sites, and particularly relates to a sand prevention device for construction sites. Background Technique

[0002] In construction sites, dusty weather is a very common problem, which not only affects the construction progress and quality, but also poses a certain threat to the physical health of workers. Therefore, how to effectively prevent the intrusion of dust has become one of the urgent problems to be solved in the construction industry.

[0003] Traditional sand prevention measures mainly reduce the entry of dust in the air by building enclosures made of materials such as canvas or plastic film around the construction site. The intercepted sand accumulates under the canvas or plastic film. When the wind blows again, it will carry the intercepted and accumulated sand, causing the problem of secondary dust emission.

[0004] Chinese Patent with the authorization announcement number CN220319172U discloses a sand prevention device for construction sites, including a water channel and a baffle. The baffle is inserted and installed on the upper part of the inner wall of one side of the water channel. A transmission flow channel is provided inside the water channel. The baffle includes a plate body, and a transmission hole is provided inside the plate body. An inlet is provided inside the water channel, and the inlet communicates with the transmission hole; the water channel includes a concave plate, a fixing plate and a screw. There are two fixing plates, and the two fixing plates are respectively fixed on both sides of the concave plate. A number of screws are respectively screwed inside the two fixing plates. This type blocks dust by installing a baffle. The water in the construction site is transmitted through the water channel, and at the same time, the dust blocked by the baffle is collected. The water channel includes a concave plate, which can effectively block the wind from directly blowing the dust inside the concave plate. At the same time, water can be passed inside the concave plate to adsorb the dust, effectively avoiding the secondary blowing of the dust.

[0005] However, the following problems still exist in the comparative document:

[0006] In the comparative document, by semi-burying the concave plate into the ground, while the concave plate serves as a drainage channel, the sand intercepted by the baffle is collected and conveyed, avoiding secondary dust emission when the wind blows again. However, in actual use scenarios, in areas and seasons with frequent dusty weather, the precipitation is often not large. Then, it is difficult to achieve the effect of avoiding secondary dust emission only through the daily drainage volume in the project.

[0007] The baffle used in the comparative document is made of an integral plastic material. When encountering strong winds, the baffle directly faces the wind and receives a large pressure, easily causing problems such as bending deformation or even breakage, which is not conducive to long-term erection and use. Content of the Utility Model

[0008] In order to overcome the deficiencies of the prior art, the technical problem to be solved by the present utility model is to adopt a wavy baffle, which greatly improves the structural strength of the baffle, enables the baffle to withstand greater pressure when facing the wind, avoids the problem that the baffle is bent or even broken under excessive wind pressure, improves the service life of the sand prevention device, and further improves the structural strength of the baffle by setting a secondary plate. After the sand is blown and hits between the baffle and the secondary plate, it is intercepted, and the sand enters the space formed between the baffle and the secondary plate through the collection holes for sand collection, avoiding secondary dust generation when the wind blows again.

[0009] In order to achieve the above object, the present utility model provides the following technical solution: A sand prevention device for construction sites, including a panel, two vertical frames are symmetrically and fixedly connected to both ends of the upper side of the panel, a cross beam is fixedly connected between the tops of the two vertical frames, a baffle is fixedly connected between the two vertical frames, the baffle is in a uniform wave shape, and the top of the baffle is fixedly connected to the cross beam.

[0010] A secondary plate is fixedly connected to each concave area on the windward side of the baffle, each secondary plate is in a folded angle shape, a plurality of collection holes are uniformly distributed on both sides of each secondary plate, and each collection hole communicates with the space formed between the baffle and the secondary plate and points downward.

[0011] A collection box is fixedly connected to the bottom of the panel, the space formed by the baffle and the secondary plate penetrates the panel and communicates with the inside of the collection box, and a closing plate is slidably connected to one side of the collection box.

[0012] A plurality of support feet are symmetrically and fixedly connected to the four corners at the bottom end of the collection box.

[0013] In summary, compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] (1) By adopting a wavy baffle, the structural strength of the baffle is greatly improved, enabling the baffle to withstand greater pressure when facing the wind, avoiding the problem that the baffle is bent or even broken under excessive wind pressure, and improving the service life of the sand prevention device.

[0015] (2) By setting a secondary plate, the structural strength of the baffle can be further improved, and after the sand is blown and hits between the baffle and the secondary plate, it is intercepted, and the sand enters the space formed between the baffle and the secondary plate through the collection holes for sand collection, avoiding secondary dust generation when the wind blows again.

[0022] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0023] Refer to Figures 1-6 , a sand prevention device for a construction site, including a panel 32, a baffle 29 is fixedly connected to the panel 32, the baffle 29 is in a uniform wave shape, a secondary plate 30 is fixedly connected to each concave area on the windward surface of the baffle 29, each secondary plate 30 is in a folded angle shape, and collection holes 31 are uniformly distributed on both sides of each secondary plate 30, and each collection hole 31 communicates with the space formed between the baffle 29 and the secondary plate 30 and points downward.

[0024] By adopting the wave-shaped baffle 29, the structural strength of the baffle 29 is greatly improved, so that the baffle 29 can withstand greater pressure when facing the wind, avoiding the problem that the baffle 29 is pressed and bent or even broken due to excessive wind force, and improving the service life of the sand prevention device.

[0025] And by setting the secondary plate 30, the structural strength of the baffle 29 can be further improved, and the sand is intercepted after being blown and hit between the baffle 29 and the secondary plate 30, and the sand enters the space formed between the baffle 29 and the secondary plate 30 through the collection holes 31 to collect the sand, avoiding secondary dust generation when the wind blows again.

[0026] Refer to Figure 3 、 5 , two vertical frames 27 are symmetrically and fixedly connected to both ends of the upper side of the panel 32, a cross beam 28 is fixedly connected between the tops of the two vertical frames 27, the two vertical frames 27 are fixedly connected to both sides of the baffle 29, and the top of the baffle 29 is fixedly connected to the cross beam 28.

[0027] By setting the vertical frames 27 and the cross beam 28, the structural strength of the baffle 29 can be further improved, and the service life of the sand prevention device can be improved.

[0028] Refer toFigure 5 At the bottom of the panel 32, a collection box 24 is fixedly connected. The space formed by the straight line of the baffle 29 and the auxiliary plate 30 penetrates through the panel 32 and communicates with the inside of the collection box 24. One side of the collection box 24 is slidably connected with a closing plate 25. At the four corners of the bottom end of the collection box 24, a plurality of supporting feet 26 are symmetrically distributed and fixedly connected.

[0029] By providing the collection box 24, the intercepted sand and soil can be centrally collected, and by removing the closing plate 25, the collected sand and soil can be centrally processed.

[0030] In this embodiment, initially, the worker arranges a plurality of the sand prevention devices side by side in the designated area and ensures that each sand prevention device is closely abutted against each other. Subsequently, the supporting feet 26 are firmly fixed to the ground by bolts, thereby firmly fixing all the sand prevention devices.

[0031] When there is a severe sandstorm weather, when the wind blows the sand and soil towards the baffle 29 and the auxiliary plate 30, the wind is blocked by the baffle 29 and the auxiliary plate 30. By using the wavy structure of the baffle 29, the structural strength of the baffle 29 can be greatly improved, so that the baffle 29 can withstand greater pressure when facing the wind, avoiding the problem that the baffle 29 is pressed and bent or even broken due to excessive wind force, and improving the service life of the sand prevention device.

[0032] By installing the auxiliary plate 30 in the groove on the windward side of the baffle 29, the structural strength of the baffle 29 can be further improved, further improving the service life of the sand prevention device. And when the sand and soil are blown and hit on the baffle 29 and the auxiliary plate 30, the sand and soil will slide along the inclined surfaces of the baffle 29 and the auxiliary plate 30 towards the collection hole 31 until the sand and soil enter the space formed by the baffle 29 and the auxiliary plate 30 through the collection hole 31.

[0033] When the sand and soil enter the space formed by the baffle 29 and the auxiliary plate 30, the sand and soil fall under the action of gravity. Since the opening of the collection hole 31 points downward, it prevents the sand and soil from flowing out of the collection hole 31 again, playing an effective role in intercepting the sand and soil.

[0034] Subsequently, the sand and soil directly fall into the collection box 24 for collection. After the collection box 24 is filled with the collected sand and soil, the worker can slide and remove the closing plate 25 to uniformly process the sand and soil collected in the collection box 24.
