Description

Technical Field

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

[0002] In construction sites, dusty weather is a very common problem. Especially in the northwestern regions of our country, the sandy and windy weather is severe and frequent, 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 opened inside the water channel. The baffle includes a plate body, and a transmission hole is opened inside the plate body. An inlet is opened 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. By adopting the method of installing the baffle, the dust is blocked. The accumulated 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 strong wind from directly blowing the dust inside the concave plate. At the same time, passing water inside the concave plate can adsorb the dust, effectively avoiding the secondary blowing up 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 transported, avoiding the generation of secondary dust emission when the wind blows again. However, in actual use scenarios, in areas and seasons with frequent sandy and windy weather, the precipitation is often not large. Then, only through the daily drainage volume in the project, it is difficult to achieve the effect of avoiding secondary dust emission.

[0007] The baffle adopted 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, and is prone to problems such as bending deformation or even breakage, which is not conducive to long-term erection and use. Utility Model Content

[0008] In order to overcome the deficiencies of the prior art, the technical problem to be solved by the present utility model is that when the wind is guided to blow upward after passing through the inclined baffle, and there is enough distance between the wind and the ground after passing through the baffle, so as to avoid the wind blowing the ground again and causing dust. By arranging a filter screen between the baffles, the sand and soil carried in the air flow are intercepted, and the intercepted sand and soil directly fall into the collection box, avoiding secondary dust generation. When the wind blows again, due to the shielding of the connecting rod, the wind will not directly enter the collection box and blow up the collected sand and soil again, thus effectively avoiding secondary dust generation. When the sand and soil collected in the collection box are full, the worker can slide and remove the closing plate, so that the sand and soil collected in the collection box directly flow out, which is convenient for the worker to uniformly process the collected sand and soil.

[0009] In order to achieve the above object, the present utility model provides the following technical solutions: An anti-sand device for construction sites in engineering, including a collection box, two vertical frames are symmetrically and fixedly connected to both sides of the collection box, a plurality of installation grooves are symmetrically arranged on both sides of the two vertical frames close to each other, and a plurality of uniformly spaced baffles are fixedly connected between every two opposite installation grooves. Each baffle is inclined upward, a filter screen frame is arranged between every two baffles, and a filter screen with fine mesh holes is fixedly connected in each filter screen frame.

[0010] A set of first connection grooves are arranged at the top of the windward surface of each baffle, a set of second connection grooves are arranged on the leeward surface of each baffle, connection pins are arranged at the corresponding positions of the first connection grooves and the second connection grooves on both sides of the edge of each filter screen frame, and each connection pin is inserted into the corresponding first connection groove and the second connection groove.

[0011] A closing plate is slidably connected to one side of the collection box away from the vertical frame. An inclined surface is arranged at the bottom side inside the collection box, and the end of the inclined surface away from the closing plate is the highest point. A plurality of supporting feet are symmetrically and fixedly connected at the four corners of the collection box.

[0012] A plurality of auxiliary baffles are symmetrically and fixedly connected to the upper side opening of the collection box. The inclination direction of each auxiliary baffle and the baffle is the same as that of the baffle. A plurality of connecting rods are symmetrically and fixedly connected to the opening of the collection box, and each connecting rod is fixedly connected to the auxiliary baffle.

[0013] To sum up, compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] By arranging the baffle with an inclined upward windward surface, when encountering wind and sand, the air flow is guided upward, avoiding the baffle directly facing the wind and receiving a large pressure, thereby avoiding damage to the anti-sand device and improving its service life.

[0015] When the wind is guided to blow upward after passing through the inclined baffle, and there is enough distance between the wind and the ground after passing through the baffle, so as to avoid the wind blowing the ground again and causing dust.

[0016] By setting a filter screen between the baffles, the sand carried in the air flow is intercepted, and the intercepted sand directly falls into the collection box, avoiding secondary dust generation. Brief Description of the Drawings

[0022] In order to enable those skilled in the art of this technology 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 in conjunction with the drawings in the embodiments of the present utility model.

[0023] Refer to Figures 1-5 , a sand prevention device for construction sites in engineering, including a collection box 10. A plurality of secondary baffles 21 are evenly distributed and fixedly connected at the upper opening of the collection box 10. The inclination directions of each secondary baffle 21 and the baffle 13 are the same as that of the baffle 13. A plurality of connecting rods 22 are evenly distributed and fixedly connected at the opening of the collection box 10. Each connecting rod 22 is fixedly connected to the secondary baffle 21. Two vertical frames 11 are symmetrically distributed and fixedly connected on both sides of the collection box 10. A plurality of installation grooves 12 are symmetrically distributed and opened on the two sides of the two vertical frames 11 close to each other. A plurality of baffles 13 with even intervals are fixedly connected between every two opposite installation grooves 12. Each baffle 13 is inclined upward.

[0024] By setting the baffle 13 with an inclined upward windward surface, when encountering sand and dust, the air flow is guided upward, avoiding the baffle 13 directly facing the wind and receiving a large pressure, thereby avoiding damage to the sand prevention device and improving the service life.

[0025] And when the wind is guided upward and blown after passing through the inclined baffle 13, and there is enough distance between the wind and the ground after passing through the baffle, it avoids the wind blowing the ground again and causing dust.

[0026] Refer to Figure 4, a filter screen frame 14 is arranged between every two baffles 13. A filter screen 15 with fine mesh holes is fixedly connected inside each filter screen frame 14. A set of first connection grooves 16 are opened at the top of the windward surface of each baffle 13, and a set of second connection grooves 17 are opened on the leeward surface of each baffle 13. Connection pins 18 are arranged at the corresponding positions of the first connection grooves 16 and the second connection grooves 17 on both side edges of each filter screen frame 14, and each connection pin 18 is inserted into the corresponding first connection groove 16 and second connection groove 17.

[0027] By arranging the filter screen 15 between the baffles 13, the sand carried in the airflow is intercepted, and the intercepted sand directly falls into the collection box, avoiding secondary dust emission.

[0028] Reference Figure 5 , a closing plate 19 is slidably connected to the side of the collection box 10 away from the vertical frame 11. An inclined surface 23 is arranged at the bottom side inside the collection box 10. The end of the inclined surface 23 away from the closing plate 19 is the highest point. A plurality of support feet 20 are symmetrically and fixedly connected at the four corners of the collection box 10.

[0029] By setting the closing plate 19 and the inclined surface 23, it is convenient to discharge the sand after the collection box 10 is full of the collected sand.

[0030] In this embodiment, initially, the worker arranges a plurality of this 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 support feet 20 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 towards the baffle 13, since the windward surface of the baffle 13 is inclined upwards, the wind passes through between the plurality of baffles 13 and is guided upwards, so that the force generated by the wind does not directly act on the baffle 13, effectively avoiding the problem that the baffle 13 and the entire sand prevention device are bent, deformed or even broken under the pressure of the strong wind.

[0032] And because the wind is guided upwards by the inclined baffle 13 and there is enough distance between the upward-guided wind and the ground, the problem of secondary dust emission when the wind blows the ground again after passing through the sand prevention device can be effectively avoided.

[0033] When the wind passes through between the inclined baffles 13, the sand carried in the wind and sand is intercepted by the filter screen 15, preventing the sand from passing through the sand prevention device to ensure the sand prevention effect of the sand prevention device.

[0034] The sand intercepted by the filter screen 15 slides downwards under the action of gravity and finally falls into the collection box 10 for collection. When the wind blows again, due to the shielding of the connecting rod 22, the wind does not directly enter the collection box 10 to blow up the collected sand again, thus effectively avoiding secondary dust emission.

[0035] When the sand collected in the collection box 10 is full, the worker can slide and remove the closing plate 19, so that the sand collected in the collection box 10 flows out directly, which facilitates the worker to uniformly process the collected sand.
