Description

Technical Field

[0002] During the construction process of a construction site, dust is spread everywhere. In order to improve the operation, dust reduction treatment is needed for the construction site. Common dust reduction equipment includes enclosure spraying, tower crane spraying, fog cannon, etc. Tower crane spraying and fog cannon spraying are movable spraying equipment, which can move dust reduction by spraying atomized water. However, in summer, when cooling is required for operations, or due to continuous operations on the ground, continuous dust reduction is required on the working ground, and enclosure spraying is usually used.

[0003] The existing fence spraying is to build a fence on the working ground of the construction, then install pipes on the fence, install nozzles at intervals on the pipes, pump water into the pipes through a water pump, and then spray water mist through the nozzles to continuously reduce dust on the working ground of the construction. However, since the pipes are installed on the fence and the nozzles are fixed, when the nozzles continue to spray in the same direction, the ground under the nozzles is continuously in contact with water, which is more likely to form puddles than other ground, making it inconvenient to expand the atomized spraying surface. At the same time, when the water is sprayed along the nozzles, part of the water is sprayed out of the periphery of the fence, affecting pedestrians when they pass by, and in windy environments, after the water is sprayed, the water sprayed on the inner periphery of the fence is also blown to the periphery by the wind.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-13 The present invention provides a technical solution: a dust suppression device for construction engineering, which is used to solve the problem that the sprayed water mist is concentrated in one place during the spray dust suppression process of the enclosure, and the water mist cannot be well scattered inside the enclosure after being affected by the wind. The design includes an enclosure 1 and a water pipe 2 installed on the enclosure 1. The enclosure 1 is composed of panels spliced ​​together one by one, and is fixed in the inner enclosure by multiple fixing plates. One end of the water pipe 2 is connected to a water source such as a pool, and water at the water source is pumped into the water pipe 2 by a water pump. The water pipe 2 is equidistantly installed with a connecting pipe 3, and the two ends of the connecting pipe 3 are clamped by clamps between the water pipe 2.

[0033] The design of pipe 3 is as follows Figure 6As shown in , mounting clamps 35 are respectively provided at both ends of the pipe 3. When the pipe 3 and the water pipe 2 are assembled, the mounting clamps 35 are first clamped on the water pipe 2, so as to increase the sealing of the water pipe 2 and the pipe 3. In order to maintain the installation stability of the pipe 3 at the enclosure 1, the designed clamping member includes a semi-ring sleeve 31 sleeved on the outside of the pipe 3, and a group of mounting clips 32 are provided at the bottom of the semi-ring sleeve 31, and the two mounting clips 32 are fixed by bolts 33, and the top of the semi-ring sleeve 31 is connected with a rolling belt 34. After the pipe 3 is installed in the water pipe 2, the semi-ring sleeve 31 is first opened and clamped on the outside of the pipe 3. The semi-ring sleeve 31 itself has a certain shrinkage. After the semi-ring sleeve 31 is installed, it is clamped on the enclosure 1 separately by the mounting clips 32, and then the mounting clips 32 are clamped and fixed on the enclosure 1 by bolts 33. In order to increase stability, the rolling belt 34 is tied to the outside of the pipe 3 by passing the rolling belt 34 through the top of the semi-ring sleeve 31.

[0034] The connecting pipe 3 is connected with an inclined pipe 4 facing the inside of the enclosure 1, and one end of the inclined pipe 4 is connected with a spherical nozzle 5, a bracket is connected between the inclined pipe 4 and the spherical nozzle 5, and the bracket is installed on the fixed plate of the enclosure 1, and the bracket includes two arc plates 11 distributed outside the inclined pipe 4, and one end of the arc plate 11 is a spherical plate 12 for clamping the spherical nozzle 5, a plurality of fixing rods 13 are connected between the two arc plates 11, and a support plate 14 is provided at the bottom of the bottom of the arc plate 11, and one end of the support plate 14 is connected to the fixed plate of the enclosure 1.

[0035] In order to change the water pressure inside the nozzle, by changing the nozzle volume, a spherical nozzle 5 is designed, and mounting holes 51 are opened at the upper and lower parts of the spherical nozzle 5. A deformable membrane 52 is connected to the mounting hole 51. The outer ring of the deformable membrane 52 is fixed to the outer wall of the mounting hole 51 by a wire ring or other fixing structure. The deformable membrane 52 is made of a ductile and impermeable material. An air blowing component 6 connected to the top of the bracket is provided on the deformable membrane 52 on the upper part of the spherical nozzle 5. The air blowing component 6 blows out gas. Afterwards, the gas causes the deformable membrane 52 to deform toward the inside of the spherical nozzle 5, thereby changing the internal volume of the spherical nozzle 5. When the deformable membrane 52 extends more inside the spherical nozzle 5, the spherical nozzle 5 is equivalent to being squeezed from the top, so that the water is concentrated in the middle part of the spherical nozzle and sprayed out with a stronger water pressure, so that the water can be sprayed farther. When the air blowing component 6 is evacuated, the deformable membrane 52 bulges at the upper part of the spherical nozzle 5, so that the internal volume of the spherical nozzle 5 increases, the water pressure decreases, and the distance the water is sprayed decreases.

[0036] An air guide housing 7 is installed at the lower part of the spherical nozzle 5, and a lifting component 8 for receiving the gas output by the air blowing component 6 is installed in the air guide housing 7. A blade 81 is installed outside the lifting component 8. The blade 81 is deformed and bent to fit on the deformable membrane 52 at the lower part of the spherical nozzle 5. The blade 81 rotates under the wind, and the blade 81 is bendable and deformable. When the blade 81 is bent and fits on the deformable membrane 52, the blade 81 promotes the water in the spherical nozzle 5 to spray out.

[0037] A nozzle grid 53 is installed at the outlet of the spherical nozzle 5 , a baffle 54 is installed on the spherical nozzle 5 to block the nozzle grid 53 , a wind speed sensor 55 is installed on the baffle 54 , and rotation adjustment components 9 are installed at both ends of the baffle 54 and the outer wall of the spherical nozzle 5 .

[0038] The baffle 54 is a curved surface, and the two ends of the baffle 54 are connected with curved plates 56 which are gradually narrowed. The curved plate 56 is connected with a mounting shaft 57, and the mounting shaft 57 is installed on the outer wall of the spherical nozzle 5. A groove is opened on the front of the baffle 54, and the wind speed sensor 55 is installed on the inner wall of the groove.

[0039] In order to prevent the wind from blowing the sprayed water mist out of the enclosure, the rotating adjustment component 9 includes a support sheet 91, which is installed on the outer wall of the spherical nozzle 5, and an electromagnetic sheet 92 is installed on the support sheet 91. One side of the curved plate 56 is made of metal. The support sheet 91 is connected to the curved plate 56 through a hinge 94, and a spring 93 is connected to the bottom of the curved plate 56. The wind speed sensor 55 monitors the wind speed change at the spherical nozzle 5, so that the electromagnetic sheet 92 is energized to generate magnetic attraction forces of different magnitudes. Because one side of the curved plate 56 is made of metal, the magnetic attraction forces of different magnitudes generated according to different wind speeds have different suction forces on the curved plate 56, so that the baffle 54 covers the nozzle grid 53 at different angles, allowing the nozzle grid 53 to change the covering area under different wind speeds, thereby reducing the wind from blowing the water at the nozzle to the periphery of the enclosure.

[0040] The air blowing assembly 6 includes a connecting plate 61 installed on the upper arc plate 11, a micro pump body 62 is installed at one end of the connecting plate 61, a bell nozzle 63 is installed at the output end of the micro pump body 62, and the bell nozzle 63 is aligned with the deformable membrane 52 on the upper part of the spherical nozzle 5, and two air delivery pipes 64 are connected to the outer wall of the bell nozzle 63, and the bottom ends of the two air delivery pipes 64 are connected to the lifting component 8.

[0041] The lifting component 8 includes a gas strut 84, the telescopic end of which is mounted on the deformable membrane 52 at the bottom of the spherical nozzle 5, and the bottom of the gas output part of the gas strut 84 is connected to a connecting air pipe 82, which is rotatably mounted on the air guide shell 7, and a return spring 85 is sheathed on the outside of the connecting air pipe 82. The two conveying air pipes 64 are connected to a mounting pipe 83, and the mounting pipe 83 is connected to the connecting air pipe 82.

[0042] The air guide housing 7 is in the shape of an ellipsoid and is provided with a plurality of air inlets 71 . An elastic curved rod 72 is connected to the gas output end housing of the gas strut 84 , and the elastic curved rod 72 is connected to the blade 81 .

[0043] During specific use, the water pump pumps water from the water source into the water pipe 2. Due to the design of the inclined pipe 4, the sprayed water is sprayed in the inner enclosure of the enclosure 1 in a parabolic manner, which is more conducive to contacting the dust in the form of water mist to achieve the effect of dust reduction. In order to avoid long-term spraying with uniform water pressure, which causes excessive accumulation of soil water at the nozzle position to form puddles and different effects of water mist spraying, the micro pump body 62 is started. When the micro pump body 62 blows out gas, the gas in the trumpet nozzle 63 is concentratedly contacted with the deformable membrane 52, so that the deformable membrane 52 is deformed toward the inside of the spherical nozzle 5. At the same time, since the delivery air pipe 64 is connected to the trumpet nozzle 63, the gas can be blown into the output part of the gas strut 84 along the delivery air pipe 64 through the connecting air pipe 82. The internal air pressure of the gas strut 84 increases, so that the telescopic part of the gas strut 84 begins to lift the deformed lower part. Membrane 52, since the blade 81 is designed to be a spheroid, when the gas support rod 84 supports the deformable membrane 52 upward, the blade 81 begins to stretch and fit the lower part of the deformable membrane 52, and when wind blows, the blade 81 can rotate, so that the deformable membrane 52 rolls, accelerating the flow of water, thereby reducing the internal volume of the spherical nozzle 5, increasing the pressure of the sprayed water, and spraying the water mist farther. When the micro pump body 62 is started to pump air, the upper deformable membrane 52 bulges upward, and the gas support rod 84 at the bottom contracts, causing the lower deformable membrane 52 to bulge downward, thereby increasing the internal lift of the spherical nozzle, reducing the sprayed water pressure, and reducing the spraying distance of the water mist, so that the water mist sprayed by the nozzle is different in distance and water pressure, which not only realizes dust reduction by spraying water mist at different distances, but also avoids the formation of puddles and reduces the waste of water resources.
