Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of atmospheric dust fall, in particular to a green dust fall equipment for building construction. BACKGROUND

[0002] Spray dust fall refers to the technology of dispersing water into mist droplets to spray towards dust sources to inhibit and capture dust, and its principle is that the extremely small particles generated by spraying have a surface tension of basically zero, and can quickly absorb various size dust particles in the air when sprayed into the air to form effective dust control. This method has good effect on dust control and fall in large open areas, especially in building construction areas.

[0003] The existing building construction dust fall specific implementation relies on a three-way joint on a water pipe in series, a spray head capable of spraying is arranged on the three-way joint, a water pump will pass the filtered water along the water pipe to the three-way joint, and finally along the spray head to spray out. Although the spray head can spray water mist, the spray direction is relatively single, the spray range is limited, and there is a dead angle of spraying. In addition, the spray degree of the spray head in series on the water pipe cannot be adjusted, or can only be uniformly adjusted by relying on uniform water pressure, and the multiple spray heads in series on the same water pipe are scattered or spanned in each building construction area. Some construction areas have high dust fall demand, and some construction areas have low dust fall demand. The spray head under such uniform adjustment cannot meet the different dust fall demands of different areas, that is, the spray head cannot be independently adjusted according to the dust fall demand, and the applicability is poor.

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, purposes and effects of the application easy to understand, the application is further described below in conjunction with specific embodiments.

[0030] As Figures 1 to 9 shown, the application includes the following embodiments:

[0031] Embodiment 1: a building construction green dust falling device for building construction dust falling, comprising a water pump 1 and a water pipe 11 connected with the water pump 1; the water pipe 11 is communicated with a tee joint 3; a branch opening of the tee joint 3 is rotationally and sealingly connected with a rotating sleeve 4; an end of the rotating sleeve 4 away from the tee joint 3 is rotationally connected with an end cover 5; an inner side of the end cover 5 is fixedly connected with a center rod 6; a lower end of the center rod 6 is fixedly connected with an inner wall of the tee joint 3; an inner wall of the rotating sleeve 4 is fixedly connected with a blade 41; the blade 41 drives the rotating sleeve 4 to rotate under the impact of water flow; the rotating sleeve 4 is symmetrically provided with a seat hole 42 on a circumferential outer wall; the seat hole 42 penetrates the inner and outer walls of the rotating sleeve 4; a cylindrical spray seat 7 is movably and sealingly connected in the seat hole 42; the spray seat 7 is provided with an atomizing nozzle 71 on a circumferential outer wall; the atomizing nozzle 71 is exposed from the seat hole 42 in a dust falling working state; the spray seat 7 is provided with a liquid inlet hole 72 near an end close to the center rod 6, which is communicated with the atomizing nozzle 71; a first bevel gear 61 is fixedly connected on an outer wall of the center rod 6; a rod sleeve 62 is rotationally connected on the outer wall of the center rod 6; two second bevel gears 63 meshing with the first bevel gear 61 are rotationally connected on an outer wall of the rod sleeve 62; the second bevel gears 63 are connected with the spray seat 7 through connecting rods 64; the atomizing nozzle 71 sprays mist to capture dust in the air of the building construction environment and complete separation of particles in the air.

[0032] Before using the dust falling device, the water pipe 11 is unfolded and installed on the corresponding building construction fence or the building construction position needing to spray water mist for dust falling, then the water pump 1 is started according to the need of dust falling, the water pump 1 inlet communicates with the water tank (not shown in the figure), the water pump 1 outlet communicates with the water pipe 11, the filtered water is discharged into the water pipe 11 through the water pump 1, the water enters into the three-way joint 3, the water flows into the branch of the three-way joint 3 along the three-way joint 3, and finally enters into the inside of the rotating sleeve 4. Since the inner wall of the rotating sleeve 4 is fixedly connected with the blade 41, the blade 41 in the rotating sleeve 4 is impacted by the water flow and drives the rotating sleeve 4 to rotate. The rotating sleeve 4 drives the spray seat 7 in the seat hole 42 to rotate around the center rod 6 in the rotating process. Since the outer wall of the center rod 6 is fixedly connected with the first bevel gear 61, the first bevel gear 61 meshes with the two second bevel gears 63. The second bevel gears 63 revolve around the center rod 6 and mesh with the first bevel gear 61 in the process of revolution, so that the second bevel gears 63 revolve around the center rod 6 while rotating. The second bevel gears 63 drive the connecting rod 64 to rotate in the process of rotation. The connecting rod 64 drives the spray seat 7 to rotate in the process of rotation. The spray seat 7 drives the atomizing nozzle 71 on the outer wall to rotate in the process of rotation. Thus, the spray seat 7 with the atomizing nozzle 71 rotates around the center rod 6 while revolving. The water flowing out of the branch of the three-way joint 3 is sprayed out along the liquid inlet hole 72 and the atomizing nozzle 71 after passing through the inside of the rotating sleeve 4. Since the atomizing nozzle 71 on the spray seat 7 revolves around the center of the spray seat 7, the atomizing nozzle 71 can be sprayed in the circumferential direction of the spray seat 7. The spraying direction is vertical. The spray seat 7 drives the atomizing nozzle 71 to revolve around the center rod 6, so that the position of the atomizing nozzle 71 on the circumferential outer wall of the rotating sleeve 4 changes, thereby enabling the atomizing nozzle 71 to realize omnidirectional spraying. The water vapor formed by the spraying contacts the dust in the air, so that the water vapor captures or adsorbs the dust. After the dust in the air is adsorbed by the water vapor, it falls down, achieving the purpose of dust falling around the building construction environment. In the case that the water pump 1 stops working, the water pipe 11 has no water flow entering into the three-way joint 3, the water flow stops impacting the blade 41, and the blade 41 and the rotating sleeve 4 stop rotating. The driving mode of the rotating sleeve 4 can also be that the inner wall is provided with teeth, and a corresponding gear is matched, and the gear is driven by a micro motor. However, the present application utilizes water flow impact to rotate, and has the energy-saving effect.

[0033] The present application drives the atomizing nozzle 71 on the spray seat 7 to rotate while revolving through the cooperation of the water flow impacting the blade 41 in the rotating sleeve 4 and the first bevel gear 61 and the second bevel gear 63, so that the atomizing nozzle 71 on the spray seat 7 sprays without dead angle, and the dust falling effect around the building construction is improved.

[0034] In the embodiment 2, the center of the spray seat 7 is provided with a connecting groove 73 along the axial direction; the connecting rod 64 is square in cross section; the connecting rod 64 is slidingly and sealingly connected in the connecting groove 73; the spray seat 7 is connected with the second bevel gear 63 through the first tension spring 65 on the side close to the central rod 6.

[0035] During the water flowing through the tee joint 3, the water pressure will have an outward extrusion force on the spray seat 7, so as to push the spray seat 7 away from the central rod 6. During the process of the spray seat 7 moving away from the central rod 6, the spray seat 7 will move along the seat hole 42, and the connecting groove 73 and the connecting rod 64 will slide. The spray seat 7 will pull the corresponding first tension spring 65, so that the first tension spring 65 completes the force storage process. During the process of the spray seat 7 moving away from the central rod 6, the spray seat 7 will extend out of the seat hole 42. The spray seat 7 will drive the atomizing nozzle 71 on the arc-shaped outer wall to expose out of the seat hole 42, so that the water inside the rotating sleeve 4 can be released. Thus, the water flow will drive the vane 41 to rotate during the process of the water flow flowing through the vane 41. The vane 41 will drive the rotating sleeve 4 and the spray seat 7 to revolve during the process of the vane 41 rotating. The second bevel gear 63 and the first bevel gear 61 will mesh and drive during the process of the spray seat 7 revolving. Thus, the connecting rod 64 will rotate, and the connecting rod 64 is square in cross section. Therefore, the spray seat 7 will rotate during the process of the connecting rod 64 rotating, so as to realize the rotation of the spray seat 7.

[0036] In addition, the rotating speed of the vane 41 will increase according to the increase of the water pressure in the water pipe 11. During the process of the water pressure increasing in the water pipe 11, the force of the water in the tee joint 3 impacting on the vane 41 will increase, so that the speed of the vane 41 driving the rotating sleeve 4 to rotate will be greater. In the case of the rotating speed of the rotating sleeve 4 being greater, the centrifugal force on the spray seat 7 will be greater, so that the spray seat 7 will be farther away from the central rod 6. Thus, the exposed area of the atomizing nozzle 71 on the arc-shaped outer wall of the spray seat 7 will be greater, so that more water vapor or water mist will be sprayed, and the atomizing degree of the atomizing nozzle 71 on the surrounding environment will change with the water pressure in the water pipe 11. During the process of the water pump 1 stopping working, the water pressure in the water pipe 11 and the tee joint 3 will decrease, and the vane 41 will also stop rotating. The first tension spring 65 will pull the spray seat 7 to move along the seat hole 42 and approach the central rod 6. The spray seat 7 will drive the connecting groove 73 and the connecting rod 64 on the spray seat 7 to slide. The spray seat 7 will drive the atomizing nozzle 71 on the arc-shaped outer wall to retract into the seat hole 42 and be shielded by the seat hole 42. Thus, the atomizing nozzle 71 will be shielded, so as to realize the protection of the atomizing nozzle 71 under the condition of stopping working. The dust and dirt outside the environment cannot fall on the exposed atomizing nozzle 71. The impurities attached to the arc-shaped outer wall of the spray seat 7 will be scraped off during the process of the spray seat 7 rotating into the seat hole 42.

[0037] The embodiment 3: the arc outer wall of the spray seat 7 is connected with the anti-off ring 75, which is located at the inner side of the rotating sleeve 4 and close to the center rod 6; the inner section of the rotating sleeve 4 is stepped; the adjusting groove 43 is arranged on the inner wall of the rotating sleeve 4 along the radial direction; the adjusting block 8 is slidably connected in the adjusting groove 43; the adjusting hole 44 is arranged on the arc outer wall of the rotating sleeve 4; the adjusting platform 9 with the hexagonal groove 91 is rotatably connected in the adjusting hole 44; the adjusting rod 92 is rotatably connected in the adjusting groove 43; the adjusting rod 92 extends into the adjusting hole 44 and is fixedly connected with the adjusting platform 9; the adjusting block 8 is threadedly connected with the thread on the outer wall of the adjusting rod 92; the adjusting block 8 extends out of the adjusting groove 43 and can be contacted by the anti-off ring 75.

[0038] In the embodiment, the contact surface of the adjusting block 8 and the anti-off ring 75 is provided with the inverted L-shaped groove 81; the other end of the inverted L-shaped groove 81 is communicated with the lower inner wall of the adjusting groove 43; one end of the inverted L-shaped groove 81 is slidably connected with the driving piece 82 and the other end is slidably connected with the driven piece 83; the contact position of the driving piece 82 and the driven piece 83 is the inclined surface, which can be inclinedly driven; the driving piece 82 is horizontally arranged and the driven piece 83 is vertically arranged; the upper end of the driven piece 83 is connected with the corner of the inverted L-shaped groove 81 through the second tension spring 84; the lower inner wall of the adjusting groove 43 is provided with the piece groove 45; the lower end of the driven piece 83 can be clamped in the piece groove 45.

[0039] The tee joint 3 in the dust falling device is connected with the sleeve 4 and the corresponding spray seat 7 in series on the water pipe 11. The water pipe 11 in the dust falling device is generally installed around the building construction, and the span of the water pipe 11 is generally large. The spraying degree of some areas on the same water pipe 11 is large, and the spraying degree of some areas is small, or even some areas need spraying and some areas do not need spraying. Therefore, the spraying degree of the single atomizing nozzle 71 is adjusted according to the specific surrounding environment demand to meet the different dust falling needs on the same water pipe 11, which is more suitable and saves water resources. Specifically, the adjusting table 9 in the adjusting hole 44 is rotated, the hexagonal groove 91 on the adjusting table 9 is inserted into the hexagonal wrench, the adjusting table 9 is driven to rotate, and the adjusting rod 92 is rotated in the adjusting groove 43 during the rotation of the adjusting table 9. The outer wall of the adjusting rod 92 is in threaded transmission connection with the adjusting block 8, so that the adjusting rod 92 is rotated to drive the adjusting table 9 to slide along the adjusting groove 43 during the rotation of the adjusting table 9. The adjusting table 9 can move close to or away from the center rod 6. The adjusting table 9 extends out of the adjusting groove 43, and the anti-extraction ring 75 moves away from the center rod 6 during the extension of the spray seat 7 out of the seat hole 42. The anti-extraction ring 75 contacts the adjusting block 8 after moving away from the center rod 6, and the adjusting block 8 limits the anti-extraction ring 75. The farther the anti-extraction ring 75 moves away from the center rod 6, the larger the area of the atomizing nozzle 71 on the spray seat 7 is exposed, and the larger the water mist sprayed by the atomizing nozzle 71 on the spray seat 7 is. The closer the anti-extraction ring 75 is to the center rod 6, the smaller the area of the atomizing nozzle 71 on the spray seat 7 is exposed, and the smaller the water mist sprayed by the atomizing nozzle 71 on the spray seat 7 is. Thus, the area of the atomizing nozzle 71 on the spray seat 7 is changed by limiting the position of the anti-extraction ring 75, and the anti-extraction ring 75 is limited by the adjusting block 8. Therefore, the closer the adjusting block 8 is to the center rod 6, the smaller the water mist sprayed by the atomizing nozzle 71 on the spray seat 7 is, and vice versa.

[0040] Further, in order to avoid the anti-extraction ring 75 extruding the adjusting block 8 to overcome the outer thread of the adjusting rod 92 in the adjusting groove 43, a reverse L-shaped groove 81 is arranged in the adjusting block 8. During the process that the anti-extraction ring 75 approaches the adjusting block 8, the driving piece 82 at one end of the reverse L-shaped groove 81 is extruded, the driving piece 82 is pressed close to the corner of the reverse L-shaped groove 81, and the driving piece 82 is pressed to move down the driven piece 83 through the inclined surface transmission. The driven piece 83 moves down and is clamped into the corresponding piece groove 45 to lock the adjusting block 8 in the adjusting groove 43, so that the axial position of the spray seat 7 in the seat hole 42 is stable, and the adjusting block 8 is prevented from shaking and shifting during the rotation of the sleeve 4. During the process that the anti-extraction ring 75 moves away from the adjusting block 8, the second tension spring 84 pulls the driven piece 83 to move up, the driven piece 83 is pulled out of the piece groove 45, and the driven piece 83 pushes the driving piece 82 to extend out of the reverse L-shaped groove 81 again through the inclined surface transmission. The adjusting block 8 is unlocked in the adjusting groove 43, and then the adjusting rod 92 can be controlled to drive the adjusting block 8 to adjust and slide in the adjusting groove 43.

[0041] In this embodiment, the rotating sleeve 4 is combined by the upper sleeve 48 and the lower sleeve 49; the upper sleeve 48 and the lower sleeve 49 are rotationally and sealingly connected; the seat hole 42 is arranged on the upper sleeve 48; the blade 41 is connected to the lower sleeve 49; the pin slot 46 is arranged on the upper sleeve 48 and penetrates the upper sleeve 48; the lower sleeve 49 is provided with a plurality of lower insertion slots 491 at the position in contact with the upper sleeve 48; the plug pin 47 can be inserted into the lower insertion slot 491.

[0042] In this embodiment, the rotating sleeve 4 is combined by the upper sleeve 48 and the lower sleeve 49; the upper sleeve 48 and the lower sleeve 49 are rotationally and sealingly connected; the seat hole 42 is arranged on the upper sleeve 48; the blade 41 is connected to the lower sleeve 49; the pin slot 46 is arranged on the upper sleeve 48 and penetrates the upper sleeve 48; the lower sleeve 49 is provided with a plurality of lower insertion slots 491 at the position in contact with the upper sleeve 48; the plug pin 47 can be inserted into the lower insertion slot 491.

[0043] In different construction environments, the dust reduction requirements are different. Some construction environments require single-direction spraying, and some construction environments require multi-direction spraying. In this way, the rotating sleeve 4 can be locked or unlocked according to the dust reduction requirements. When the rotating sleeve 4 is unlocked, the rotating sleeve 4 can rotate with the blade 41. The rotating rotating sleeve 4 drives the spray seat 7 with the atomizing nozzle 71 to rotate and revolve, achieving all-direction dust reduction. When the rotating sleeve 4 needs to be locked, the bolt 472 needs to be loosened. The holding end of the bolt 472 is larger than the width of the operation slot 471. After the holding end of the bolt 472 is separated from the contact with the outer wall of the upper sleeve 48, the plug pin 47 is unlocked. Then, the rotating sleeve 4 is rotated to change the position of the spray seat 7 in the circumferential direction of the rotating sleeve 4. The spray seat 7 is directed to the direction to be sprayed. The bolt 472 is lifted to drive the plug pin 47 to move upward. The plug pin 47 slides and moves upward along the pin slot 46. One of the plurality of upper insertion slots 51 is aligned with the pin slot 46. Therefore, the plug pin 47 is inserted into the upper insertion slot 51, achieving the connection between the rotating sleeve 4 and the end cover 5. Finally, the bolt 472 is tightened, and the holding end of the bolt 472 abuts against the outer wall of the rotating sleeve 4. In this way, the rotating sleeve 4 is locked, and the position of the spray seat 7 in the circumferential direction of the rotating sleeve 4 is locked, meeting the dust reduction requirements of construction.

[0044] Further, the rotating sleeve 4 is combined by the upper sleeve 48 and the lower sleeve 49, so that the upper sleeve 48 in the rotating sleeve 4 can rotate, the control pin 47 is inserted into the lower insertion slot 491 from the upper insertion slot 51, the length of the control pin 47 is equal to the vertical length of the upper sleeve 48, so that the upper sleeve 48 and the lower sleeve 49 are connected, the upper sleeve 48 is disconnected with the end cover 5, the blade 41 on the inner side of the lower sleeve 49 rotates to drive the spray seat 7 on the upper sleeve 48 to move, if the upper sleeve 48 in the rotating sleeve 4 needs to be locked, the control pin 47 is inserted into the upper insertion slot 51 from the lower insertion slot 491, so that the upper sleeve 48 and the lower sleeve 49 are unlocked, the upper sleeve 48 is fixedly connected with the end cover 5, so that the blade 41 and the lower sleeve 49 in the rotating sleeve 4 rotate freely in the liquid flow process, the liquid flow resistance is reduced, and the blade 41 rotating is unloaded.

[0045] In the embodiment 5, the first bevel gear 61 is arranged close to the blade 41 relative to the second bevel gear 63, and one end of the first bevel gear 61 close to the blade 41 is arranged in a conical shape.

[0046] After the liquid passing through the blade 41 impacts on the conical end of the first bevel gear 61, the conical end of the first bevel gear 61 guides the liquid, reduces the impact of the liquid on the first bevel gear 61 and the second bevel gear 63, and achieves the purposes of noise reduction and resistance reduction.

[0047] In the embodiment 6, the arc-shaped outer wall of the spray seat 7 is provided with an annular anti-disengagement groove 74, and the anti-disengagement ring 75 is rotationally connected in the anti-disengagement groove 74. By rotationally connecting the anti-disengagement ring 75 with the spray seat 7, after the anti-disengagement ring 75 contacts the adjusting block 8, the anti-disengagement ring 75 does not rotate with the spray seat 7, the friction between the anti-disengagement ring 75 and the adjusting block 8 is reduced, and the rotation resistance of the spray seat 7 is reduced.

[0048] In the embodiment 7, the first tension spring 65 is sleeved on the outer wall of the central rod 6, and the end cover 5 is arranged in a transparent shape. The central rod 6 can guide and support the first tension spring 65, and the influence of water flow on the first tension spring 65 is reduced; the internal structure can be observed through the end cover 5.
