Description

Technical Field

[0001] The invention relates to the field of construction, and in particular to a dust suppression canopy with dust removal and dust suppression functions used in construction sites. Background Art

[0002] In construction sites, especially when earth excavation is involved, a lot of dust is generated, and dust suppression and dust prevention are required. Especially when construction is carried out in a site with dense buildings, if the dust is very large, it will cause dust pollution to the surrounding office space. Chinese patent CN212295717U discloses a dust suppression canopy device, which uses a slide, a truss, and a drive device. The drive device drives the truss to drive the dustproof net to fold along the slide. This patent is convenient for folding, but the dustproof net cannot be opened automatically. The mobile dust suppression canopy disclosed in Chinese patent 202121681514.X uses two sets of sliding components and a drive device to drive the dustproof net to fold from both sides to the middle or unfold from the middle to both sides. Although the automatic folding and unfolding of the dustproof net can be achieved, the number of sliding components and drive devices is relatively large, and the structure is relatively complex.

[0003] Moreover, the dust suppression curtain of the above-mentioned technical solution will sag to a certain height after being folded, thereby reducing the height of the dust suppression curtain. As a result, when building the dust suppression curtain, the drooping height of the dust suppression curtain when folded must be considered, so that the overall height of the dust suppression curtain needs to be increased by the drooping height of the dust suppression curtain when folded.

[0004] The above-mentioned dust suppression canopy can only prevent the dust in the construction site from spreading to the outside of the construction site and causing environmental pollution to the surrounding area, but it cannot automatically remove dust. Summary of the invention

[0037] With respect to the above technical solution, preferred embodiments are now cited and specifically described in conjunction with drawings.

[0038] The dust suppression canopy capable of removing dust during the entire construction period of the present invention comprises a first bracket and a second bracket located on opposite sides of a foundation pit. Figure 1 The first bracket and the second bracket respectively include support columns 10 arranged in rows at intervals, and a cross beam 12 is arranged on the top of the support column 10. The support column 10 is located in the foundation pit. The support column 10 includes a retaining pile. A cast-in-place pile is used outside the foundation pit. Secondary concrete pouring is performed on the top of the retaining pile and the cast-in-place pile to form a crown beam. A round tube column is fixed on the crown beam by bolts to form the support column 10. A cross beam 12 is arranged on the top of the row of support columns 10. Support ribs are fixedly connected at intervals on the outer periphery of the top of the support column 10, and the cross beam 12 is fixedly connected to the top of the support column 10 and the support rib. The cross beam 12 is a steel truss structure.

[0039] A plurality of dust suppression canopy units are arranged on the cross beam 12, and the dust suppression canopy units can be folded and unfolded independently, or folded and unfolded in a linked manner.

[0040] The dust suppression canopy unit includes: Figure 2A slide rail 14 is fixedly arranged horizontally in the length direction of the steel truss structure on the first bracket and the second bracket. The slide rail 14 is an I-shaped structure, including an upper slide groove opening upward and a lower slide groove opening downward, and both the upper slide groove and the lower slide groove are arranged horizontally. A plurality of slider structures 15 are arranged on the slide rail 14, and the slider structure 15 at the most side of one end of the slide rail 14 is fixedly arranged on the slide rail 14, and the other slider structures 15 are all arranged to slide. Figure 3 and Figure 4 The slider structure 15 includes a frame structure 151, and the frame structure includes a horizontal support plate and a side plate connected and fixed on one side of the two horizontal support plates. The frame structure is open at three ends. At least one set of rollers 152 are arranged opposite to each other on the two horizontal support plates, and the rollers 152 are respectively clamped in the upper slide groove and the lower slide groove. A fixing bolt 153 is connected between the two horizontal support plates located on the outside of the slide rail. The distance between the two horizontal support plates is reinforced by the fixing bolt, so that the slider structure 15 can be better slid on the slide rail. A set of upper fixing hooks 154 and lower fixing hooks 155 are fixed on the side plates of the slider structure 15, and the upper fixing hooks 154 and the lower fixing hooks 155 are circular structures. A fixed pulley (not shown) is arranged under the slider structure 15.

[0041] A limit structure is provided at both ends of the slide rail 14. A first position sensor and a second position sensor are provided on the cross beams near both ends of the slide rail 14. The first position sensor is used to position the slider structure at the extreme end of the slide rail to reduce the motor speed, and the second position sensor is used to sense the final position of the slider structure at the extreme end of the slide rail to control the motor to stop.

[0042] A driving device 20 is arranged on the cross beam 12, and the driving device 20 is mounted on a mounting bracket located on the cross beam 12. The driving device 20 includes a driving motor (not shown) arranged on the driving bracket, and the driving motor adopts a servo reduction motor. A driving wheel 21 is arranged on the output end of the driving motor, a first driven wheel 22 is arranged below the driving wheel 21, and a second driven wheel 23 is arranged on one side of the driving wheel 21 and the first driven wheel 22. Support frames are respectively arranged at both ends of the cross beam 12, and guide wheels (24, 25) are arranged on the support frames. The support frames of the guide wheels (24, 25) are used to limit the position of the wire rope. The wire rope 26 is wound around the driving wheel 21, and the first driven wheel 22 and the second driven wheel 23 change the direction of the two ends of the wire rope 26 wound around the driving wheel 21 so that the wire rope is in a horizontal structure, so that the two ends of the wire rope 26 pass through the guide wheels (24, 25) and then pass through the upper fixed hook 134 on the slider structure 15 to form a wire rope 26 loop. The slider structure 15 at the outermost side of one end of the slide rail 14 is slidably arranged and fixedly connected to the wire rope 26 .

[0043] Steel wire ropes 27 and 28 are fixed to the upper fixing hook and the lower fixing hook of the slider structure 15 corresponding to the first bracket and the second bracket, respectively, to form two layers of steel wire ropes. Dust suppression curtains 30 are respectively passed through the steel wire ropes 27 located on the upper layer. The dust suppression curtains 30 are divided into two pieces along the length direction of the steel wire ropes 27. Figure 5 A traction channel 31 is sewn below the position where the dust suppression curtain 30 is inserted through the steel wire rope 27 along the length direction of the steel wire rope. The traction channel 31 is provided with several blocking rings 311 at intervals along its length, and the blocking rings 311 are made of metal. A traction rope 32 is inserted through the traction channel 31, and blocking blocks 321 are fixedly provided on the traction rope 32 on both sides of the blocking ring 311. Both ends of the traction rope 32 are respectively fixed on the upper fixing hooks of the slider structure 15. When the dust suppression curtain 30 is fixed, its two ends are respectively fixed to the steel wire rope 27 by U-shaped buckles, and at the same time, the traction rope 32 is tightened, so that the dust suppression curtain 30 is tensioned on the steel wire rope 27. Through the dual action of the traction rope and the U-shaped buckle, the dust suppression curtain 30 is tensioned on the steel wire rope 27.

[0044] Arched support devices 33 are provided at intervals along the length direction of two adjacent steel wire ropes 28 under the dust suppression curtain 30. Figure 6 to Figure 7 The arch support device 33 includes a plastic slide rail 331 and a plastic slide bar 332 respectively fixed on two adjacent steel wire ropes 28. The plastic slide bar 332 is inserted into the plastic slide rail 331. The plastic slide bar 332 and the plastic slide rail 331 can slide relative to each other to form an arch support device. Since the plastic slide bar and the plastic slide rail are made of plastic material, they have certain elasticity and support strength. Since the dust suppression curtain is located above them, a certain downward pressure is formed on the arch support device, and the arch support device can be placed to open upward and disengage, ensuring that the plastic slide bar is always inserted in the plastic slide rail. When the dust suppression curtain is unfolded, the arch support device 33 forms an upward arch support for the dust suppression curtain. When the dust suppression curtain is folded, the plastic slide bar 332 and the plastic slide rail 331 slide relative to each other, and their free ends extend obliquely downward from the wire rope 28, and the arch support device is folded accordingly. As the dust suppression curtain and the arch support device are folded synchronously, the arch support device still supports the folded dust suppression curtain to prevent the dust suppression curtain from sagging and avoid lowering the height of the dust suppression curtain. By adding the arch support device, when designing and building the dust suppression curtain, there is no need to consider the sagging height of the dust suppression curtain when it is folded, which reduces the height of the dust suppression curtain, saves materials for building the dust suppression curtain, and reduces construction costs.

[0045] A wind sensor (not shown) is provided on the first bracket or the second bracket to detect the wind force. Generally, one wind sensor is provided for about 10,000 square meters. Since there are many typhoons in the south, when the wind force is strong, the dust suppression canopy is subjected to a very large force as a whole, which may easily cause a serious accident of the dust suppression canopy collapse. Therefore, when the wind sensor detects that the wind force exceeds the threshold, the U-shaped buckle fixed in the middle of the dust suppression canopy is removed, and the traction rope on one side is loosened so that the traction rope bypasses the fixed pulley on the slider structure, and the traction rope is pulled. Since a blocking block 321 is provided on the traction rope, the blocking block 321 near one end of the bracket first drives the blocking ring near one end of the bracket in the traction channel, and drives the dust suppression canopy near the bracket to first close to one end of the bracket. As the traction rope is pulled, the dust suppression canopy gradually closes in an orderly manner on one side of the bracket, and the dust suppression canopy closed on one side of the bracket is fixed to the beam by a rope to prevent the wind from causing impact on the canopy. The two dust suppression canopies are respectively gathered at the first bracket and the second bracket by means of traction ropes, and are tied and fixed on the crossbeam.

[0046] When the wind speed decreases and it needs to be deployed, the other end of the traction rope is pulled from the first bracket and the second bracket respectively. Under the action of the blocking block and the blocking ring, the gathered dust suppression curtain is gradually deployed along the steel wire rope and then locked on the steel wire rope through the U-shaped buckle. In this way, there is no need to remove the dust suppression curtain when the wind speed is strong, avoiding the process of disassembly and reinstallation.

[0047] The dust suppression canopy is also provided with a dust and mist removal device. The dust and mist removal device includes a dust and mist removal curtain device and a dust removal device arranged around the dust suppression canopy. Figures 8 to 15 , including a water tank 40 arranged on the ground, a horizontal guide rail 41 is arranged in the water tank, and a hollow water pipe 42 is arranged above the water tank. A groove 411 is provided on the horizontal guide rail 41 along the length direction. Rectangular grooves 421 are respectively provided on the opposite sides of the water pipe 42 along its length direction. A long through hole 421 is provided on the top of the water pipe 42, and at least one fine hole 422 is provided on the bottom of the water pipe 42. A water spray pipe 423 is passed through the water pipe 42, and a plurality of spray holes are provided on the water spray pipe 423. The water spray pipe 423 is connected to the water supply pipe, and the water supply pipe is connected to the water tank, and water is supplied to the water supply pipe by a water pump. The water tank is connected to the water tank through a return pipe to form a water circuit.

[0048] The curtain 43 includes a lower sliding rod 431 and an upper sliding rod 432. Dust removal and adsorption ropes 433 are respectively provided on the lower sliding rod 431 and the upper sliding rod 432. The dust removal and adsorption ropes 433 are densely arranged to form the curtain 43. The dust removal and adsorption ropes 433 are made of water-absorbing material, and their outer peripheral surface is a fluff structure. The lower sliding rod 431 has an outer shape similar to the outer shape structure on the rectangular groove 421 of the water pipe 42, which is an arc-shaped groove structure, and the open end of the arc-shaped groove structure faces downward. Horizontal end plates 4311 that can be clamped on the rectangular groove 421 are extended on both sides of the open end of the arc-shaped groove structure. At the top of the arc-shaped groove structure, a groove 4312 protruding from the top is opened along its length direction. One end of the dust removal and adsorption rope 433 is set in the groove 4312, and passes through the groove 4312 and is located in the lower sliding rod 431. The lower sliding rod 431 is slidably disposed on the horizontal guide rail 41 , and one end of the dust removal adsorption rope 433 passes through the groove 4312 and is located in the groove 411 of the horizontal guide rail 41 .

[0049] The upper slide bar 432 has a similar shape to the shape structure below the rectangular groove 421 of the water pipe 42, and is a circular arc groove structure. Horizontal end plates 4321 that can be clamped on the rectangular groove 421 are extended on both sides of the open end of the circular arc groove structure. A groove 4322 is provided at the bottom of the circular arc groove structure along the length direction, and both ends of the groove 4322 are closed. One end of the dust removal adsorption rope 433 passes through the bottom groove 4322 of the upper slide bar 432 and is located in the groove 4322.

[0050] The curtain 43 is made into a unit structure, and the dust-proof and demisting curtain device can be composed of several curtains 43. During installation, a water tank and a horizontal guide rail 41 located on the ground and a water pipe 42 located above the horizontal guide rail 41 are arranged around the foundation pit. According to the height of the dust-suppressing skylight, several layers of water pipes 42 can be arranged, and curtains 43 are arranged between two adjacent layers of water pipes 42. Fig.15. The lower sliding rod 431 of the curtain 43 is slidably mounted on the horizontal guide rail 41 or the water pipe 42, so that one end of the dust removal adsorption rope 43 on the lower sliding rod 431 is located in the groove of the horizontal guide rail 41 or in the long through hole on the water pipe 42. The upper sliding rod 432 is slidably mounted under the water pipe 42, so that the fine hole under the water pipe 42 is located in the groove 4322 on the upper sliding rod 432. The curtain is sequentially slidably mounted between the horizontal guide rail and the water pipe or between adjacent water pipes in the form of a unit, and arranged to form a circle of curtain structures. The water supply pipe is controlled by a water pump to supply water to the water spray pipe in the water pipe 42, and water is sprayed through the water spray pipe. The water entering the water pipe 42 enters the groove of the upper sliding rod through the fine hole and soaks the dust removal adsorption rope fixed on the upper sliding rod; the lower end of the dust removal adsorption rope of the lower sliding rod sliding in the water pipe 42 is also sprayed or soaked in the water in the water pipe 42 by spraying water through the water spray pipe. Since there is water in the sink and the water pipe, due to capillary action, the lower end of the dust removal adsorption rope of the curtain 43 absorbs water from the sink or the water pipe, and the upper end of the dust removal adsorption rope is moistened by spraying water through the water spray pipe, quickly keeping the dust removal adsorption rope of the entire curtain moist, forming a dust-proof curtain. Water is sprayed regularly through the water spray pipe to keep the curtain 43 always moist. When the curtain 43 surrounds the outer periphery of the dust suppression skylight, the flying dust will be adsorbed when it encounters the curtain, and at the same time, the water from the dust removal adsorption rope slides down into the water pipe or sink. By setting a drain pipe on the sink and the water pipe 42, it can be used to regularly clean the sink and the water pipe 42.

[0051] The dust removal device is provided with an atomizing nozzle 50 at intervals of 2 meters on the crossbeams on the first bracket and the second bracket. The atomizing nozzle 50 is connected to a high-pressure water pipe, which is connected to a high-pressure dust removal humidifier, which is connected to a water source. Water is atomized by the high-pressure dust removal humidifier and supplied to the nozzle through the high-pressure water pipe, and the atomized water is sprayed out by the nozzle to form water mist dust removal.

[0052] See also Fig.16 A swing mechanism is provided on the crossbeam, and the atomizing nozzle 50 is provided on the swing mechanism. The swing mechanism includes a swing rod 51 rotatably provided on the crossbeam, a sliding sleeve 52 is sleeved on the swing rod 51, the sliding sleeve 52 is rotatably connected to one end of a connecting rod 53, and the other end of the connecting rod 53 is connected to a motor (not shown) through a rotating shaft 54, and the motor is a servo drive motor. The nozzle 50 is fixedly provided at the free end of the swing rod 51. Fig.16 In the figure, the area between the solid line and the dotted line is the displacement range of the swing rod 51.

[0053] When the motor rotates, the connecting rod 53 can be driven to rotate. As the connecting rod 53 rotates, the swing rod 51 is driven to swing through the sliding sleeve 52, and the nozzle is driven to rotate in a certain area. When removing dust, the horizontal and height position of the atomizing nozzle 50 can be adjusted by the swing mechanism as needed to expand the effective dust removal space.

[0054] The dust-proof and mist-removing curtain device is used to prevent dust from escaping from around the dust-suppression canopy, and the dust removal device is used to actively remove dust from the construction site under the dust-suppression canopy.

[0055] The dust suppression canopy structure can be divided into several independent dust suppression canopy unit areas as needed when the construction site is large, and the dust suppression canopy of each independent dust suppression canopy unit can be folded and unfolded automatically. The folding and unfolding of the dust suppression canopy in each independent area can be controlled by controlling the driving device.

[0056] When the span is large, a crossbeam can be added between the first bracket and the second bracket, so that the steel wire rope 27 is installed on the added crossbeam.

[0057] The control device is provided with a distribution box on the supporting columns of the first bracket and the second bracket respectively, and each servo drive motor control is integrated in a servo control box. Each servo control box is composed of a control box, an air switch, a four-way two-way feedback controller, a PLC controller, a remote sensing controller, a linkage controller and a bracket, ensuring that each independent dust suppression canopy unit is independently unfolded and folded, and several independent dust suppression canopy units can be linked through control. A control assembly is integrated in the guard room, and the independent action or linkage of each independent dust suppression canopy unit area is controlled through the guard room control assembly, and the action of the dust and defogging device can also be controlled.

[0058] When the dust suppression canopy is opened, the drive motors located on the first bracket and the second bracket are started to act synchronously, the drive motor drives the active wheel 21 to rotate, drives the wire rope to rotate around the first driven wheel and the second driven wheel, thereby driving the slider structure at the edge of the slide rail to move along the slide rail to one end of the slide rail, and synchronously drives the wire rope to move. Since the dust suppression canopy is arranged on the wire rope, with the movement of the slider structure, the dust suppression canopy of the wire rope at the edge gradually opens, and with the opening of the dust suppression canopy, the steel wire rope and the slider structure adjacent to it move along the slide rail, gradually making the dust suppression canopy fully open; when the first position sensor senses the movable slider structure at the edge fixedly connected to the wire rope, the drive motor decelerates, and when the second position sensor senses the slider structure, the drive motor stops. At the same time, with the displacement of the slider structure and the wire rope, the plastic slide rail and the plastic slide bar of the arch support device on the wire rope 28 also slide and displace relatively, opening to form a relatively large arch support to support the opened dust suppression canopy. When folding, the driving motor rotates in the opposite direction, and the slider structure moves along the slide rail as the wire rope rotates. When it moves to the adjacent slider structure, it drives the adjacent slider structure to move synchronously, and drives the next slider structure to move until the dust suppression curtain is completely folded. At the same time, the plastic slide rails and plastic slide strips of the arch support on the wire rope 28 also slide and move relatively to support the folded dust suppression curtain, prevent it from sagging, and reduce the height of the dust suppression curtain.

[0059] During dust prevention and demisting, first use the dust prevention and demisting curtain device to prevent dust from overflowing the construction site, control the water pump to supply water regularly and keep the curtain moist; when the construction site is dusty, start the dust removal device, and spray water outward through the high-pressure dust removal humidifier and atomizing nozzle. Because it is atomized water, the atomized water combines with the dust in the air and falls to the ground to remove dust.
