Description

Technical Field

[0001] The present invention relates to the technical field of dust reduction at construction sites, and in particular to a dust reduction structure and a dust reduction method for green construction sites. Background Art

[0002] The pace of infrastructure construction in my country is gradually accelerating. In the construction and development of cities, dust is inevitably present in construction sites. Dust pollution particularly affects people's lives and travel. In existing technologies, dust suppression devices are generally installed on the closed fences set up around the construction site. These dust suppression devices will spray the air. This spray will form small water droplets in the air. After these small water droplets mix with dust particles, they will settle the dust and achieve dust reduction treatment for the polluted air.

[0003] Existing dust suppression structures have a rotating mechanism to rotate the nozzle, allowing the nozzle to rotate 360 degrees to increase the range of the nozzle. This driving rotation method is generally driven by a motor, and its driving method requires the motor to consume electricity to achieve it. This driving method not only consumes electricity, resulting in power waste and is not environmentally friendly, but also causes the nozzle to operate against the wind during the spraying process, resulting in a reduced range of the nozzle spray.

[0004] At the same time, the nozzle spray is turned on and off by the pipeline switch valve, which requires the staff to manually open or close the switch valve. The switch valve itself cannot open or close automatically, which may cause the staff to forget to close the switch valve, causing the nozzle to work continuously and waste water resources on the construction site. Therefore, in order to solve the above problems, we propose a dust suppression structure and dust suppression method for green construction sites. Summary of the Invention

[0005] The purpose of the present invention is to provide a dust reduction structure and dust reduction method for a green construction site, so as to solve the problem proposed in the above background technology that the existing dust reduction structure has a rotating mechanism to rotate the nozzle, and its driving method needs to be realized by consuming electricity through the motor. This driving method not only consumes electricity and causes waste of electricity, but also causes the nozzle to operate against the wind during spraying, resulting in a reduction in the range of the nozzle spray; the switch of the nozzle spray is controlled by the pipeline switch valve, and the switch valve itself cannot be automatically opened or closed, which will cause the staff to forget to close the switch valve, causing the nozzle to work continuously and resulting in waste of water resources on the construction site.

[0011] The automatic water valve includes a connecting pipe B, the upper end of which is fixedly connected to the connecting pipe A, and the lower end of which is fixedly connected to the tee. An inner channel is vertically provided in the middle of the inner part of the connecting pipe B, and an arc groove is fixedly provided in the middle of the inner channel. An outer protective shell C is fixedly connected in the middle of one end surface of the connecting pipe B, and a compression spring B is connected to the interior of the outer protective shell C. One end of the compression spring B is connected to a hemispherical top block, and the hemispherical top block is movably fitted in the arc groove.

[0012] The positioning component includes an outer protective shell B, and a top block is movably penetrated by the end face of the outer protective shell B facing the rectangular through hole. Both sides of one end of the top block are fixedly connected with a compression spring A and a movable column. The movable column is located in the compression spring A. The upper and lower sides of one end of the top block are arranged and fixedly connected with two sliding frames. The end face of one end of the top block and the end face of the outer protective shell B away from the top block are connected by a compression spring A.

[0016] Preferably, the clamping plate is in an inverted L-shape, and a closed enclosure for the construction site is clamped between the vertical end wall inside the clamping plate and the top block.

[0017] Preferably, the lower end of the automatic water valve is fixedly connected to a three-way pipe, one end of the three-way pipe is connected to a water pump through a pipeline, and the water pump is connected to a water tank through a pipeline.

[0018] A dust reduction method for a dust reduction structure for a green construction site, the dust reduction method comprising the following steps:

[0019] Step A: First, push the sliding block between the two C-shaped sliding plates. The sliding block then drives the L-shaped connecting column and the top block to move inside the outer protective shell B. At this time, the vertical end wall inside the clamping plate and the top block are clamped onto the partition used on the construction site, thereby fixing the entire dust suppression device.

[0020] Step B: Next, the lateral movement of the push block toward the inner end of the outer protective shell B drives the push column to move horizontally, so that one end of the push column is inserted into the middle of the connecting pipe B. The push column then pushes the hemispherical push block inside the arc groove horizontally.

[0021] Step C: At this time, the hemispherical top block moves laterally into the outer protective shell C to compress the extension elastic force of the compression spring B, so that the hemispherical top block disengages from the arc groove, which opens the arc groove and allows the internal channel in the middle of the connecting pipe B to circulate liquid;

[0022] Step D: Then, one end of the tee pipe is connected to an external water pump. The water pump draws water from the water tank and allows the water to flow into the buffer chamber through the automatic water valve and connecting pipe A. The spray head on one side of the buffer chamber then performs a spraying operation.

[0023] Step E: The wind blows the fan blades B on the rotating column, which drives the rotating column and the driving shaft to rotate. The rotation of the driving shaft drives the driving gear to rotate. The rotation of the driving gear drives the secondary gear and the driven gear to rotate. The driven gear then drives the driven shaft, the buffer chamber, and the spray head to rotate, so that the entire spray head performs a rotary spraying operation.

[0024] Step F: After the final use, push the sliding block horizontally into the rectangular through hole again, so that the sliding block drives the top block to press the extension elastic force of the two compression springs A, releasing the pressure fixation between the top block and the closed enclosure for the construction site, so that the entire device can be removed from the closed enclosure for the construction site.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] In the present invention, when both blades A and blade B are blown by the wind, the blade B with a larger area is blown by the wind with greater force, and the blade A with a smaller area is blown by the wind with less force. When the wind blows the blade B, it causes it to swing continuously and eventually causes the blade B to rotate in the opposite direction of the wind. During the swinging of the blade B, the blade B drives the rotating column and the driving shaft at the lower end to rotate. The driving gear and the driven gear on the driving shaft engage with each other through the secondary gear, thereby making the rotation between the driving gear and the driven gear synchronous. Finally, the driven shaft on the upper side of the driven gear drives the buffer chamber and the spray head to rotate or swing. This rotation and swinging increases the spray range of the spray head, and the spray head and the blade B are oriented in the same direction, so that the spray head will follow the wind direction when spraying, further increasing the range of the spray head spray dust reduction.

[0027] When the overall positioning component and the clamping component are fixed on the closed enclosure for the construction site, the closed enclosure for the construction site squeezes the top block toward the inside of the top block, and the overall top block elastically squeezes the two compression springs A in the outer protective shell B. Then the top column at the middle of one end of the top block is inserted into the middle of the connecting pipe B, and the top column pushes the hemispherical top block inside the arc groove laterally, so that the hemispherical top block is separated from the arc groove. At this time, the internal channels set through the upper and lower sides of the connecting pipe B are in a through state. This design realizes that when the overall device is fixed, the automatic water valve is opened at the same time, so that the automatic water valve can transport water to the buffer chamber in time;

[0028] When the overall positioning component and the clamping component are removed from the closed enclosure for the construction site, the closed enclosure for the construction site no longer presses the top block, and the top block no longer presses the tension force of the compression spring A, so that the top block as a whole moves in the direction of the L-shaped connecting column under the tension force of the two compression springs A, and the top block drives the top column at one end to be pulled out of the arc groove, thereby releasing the top column from pushing the hemispherical top block. The hemispherical top block moves toward the curved surface at one end of the arc groove under the push of the tension force of the compression spring B, and finally the curved surface of the arc groove and the hemispherical top block fit together, and the hemispherical top block causes a blockage in the middle of the inner channel. At this time, the water flow cannot reach the buffer chamber through the connecting pipe A. Through this design, after the overall device is disassembled, the hemispherical top block inside the automatic water valve blocks the inner channel in time, avoiding the spray head from still spraying after the overall device is disassembled, further saving water on the construction site.

DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0039] See also Figures 1 to 8 , the present invention provides an embodiment: a dust reduction structure for a green construction site, comprising an outer protective shell A1, a wind-powered blowing component 2 is provided on one side of the upper end of the outer protective shell A1, a driven spray dust reduction component 3 is provided on the other side of the upper end of the outer protective shell A1, a clamping component 5 is fixedly provided on the lower end of the outer protective shell A1, and a positioning component 4 is connected to the rear end of the clamping component 5, wherein the wind-powered blowing component 2 comprises a rotating column 201, a fan blade A203 is fixedly connected to one side of the upper end surface of the rotating column 201, a fan blade B204 is fixedly connected to the other side of the upper end surface of the rotating column 201, the area of the fan blade B204 is larger than the area of the fan blade A203, the lower end of the rotating column 201 is fixedly connected to a driving shaft 202, and a driving gear 205 is fixedly connected around the lower end surface of the driving shaft 202.

[0040] The driven spray dust reduction component 3 includes a driven shaft 301, the upper end of the driven shaft 301 is fixedly connected to a connecting frame 302, the upper end of the connecting frame 302 is fixedly connected to a buffer chamber 303, the upper end of the buffer chamber 303 is movably connected to a connecting pipe A305, one side of the buffer chamber 303 is fixedly connected to a spray head 304, and the lower end surface of the driven shaft 301 is fixedly connected to a driven gear 306 around the periphery, the driving gear 205 and the driven gear 306 are transmitted through the secondary gear 6, and a rotating shaft is fixedly connected through the middle of the secondary gear 6, and the upper and lower ends of the rotating shaft are movably connected to the upper and lower end walls inside the outer protective shell A1 respectively.

[0041] The direction from blade A203 to blade B204 is the direction of blade B204, and the direction of blade B204 is consistent with the direction of the spray head 304. The driving gear 205 and the driven gear 306 are transmitted through the secondary gear 6, so that the driving gear 205 and the driven gear 306 move synchronously, and the driving shaft 202 in the middle of the driving gear 205 and the driven shaft 301 in the middle of the driven gear 306 also rotate synchronously. Finally, the blade B204 on the driving shaft 202 and the spray head 304 on the driven shaft 301 rotate synchronously, so that the direction of blade B204 and the direction of the spray head 304 are always consistent.

[0042] Since the area of the fan blade B204 on one side of the upper end of the rotating column 201 is larger than the fan blade A203, and the entire device is installed outdoors, when the fan blades A203 and B204 are both blown by the wind, the fan blade B204 with a larger area is blown by the wind with greater force, and the fan blade A203 with a smaller area is blown by the wind with less force, then when the wind blows the fan blade B204, it swings continuously and eventually rotates the fan blade B204 in the opposite direction of the wind. During the swinging process of the fan blade B204, the fan blade B204 drives the rotating column 201 and the driving shaft 202 at the lower end to rotate. The driving gear 205 and the driven gear 306 on the driving shaft 202 are engaged through the secondary gear 6, so that the rotation between the driving gear 205 and the driven gear 306 is synchronized, and finally the driven shaft 301 on the upper side of the driven gear 306 drives the buffer chamber 303 and the spray head 304 to rotate or swing. This rotation and swinging increases the spray range of the spray head 304, and the directions of the spray head 304 and the fan blades B204 are consistent, so that the spray head 304 will follow the wind direction when spraying, further increasing the spray dust reduction range of the spray head 304.

[0043] The clamping component 5 includes a clamping plate 501, one end face of which is provided with a rectangular through hole 502, and both sides of the end face of the front end of the clamping plate 501 are fixedly connected to a C-shaped sliding plate 504, and a sliding block 505 is movably provided between the two C-shaped sliding plates 504. The setting of the two C-shaped sliding plates 504 limits the sliding block 505 to only be able to move horizontally, and both sides of the rear end of the sliding block 505 are fixedly connected with L-shaped connecting columns 503, and both sides of the inside of the clamping plate 501 are provided with L-shaped guide grooves 506, and the two L-shaped connecting columns 503 are movably located in the two L-shaped guide grooves 506.

[0044] The automatic water valve 7 includes a connecting pipe B701, the upper end of the connecting pipe B701 is fixedly connected to the connecting pipe A305, the lower end of the connecting pipe B701 is fixedly connected to the tee pipe 8, an inner channel 702 is vertically provided in the middle of the inner part of the connecting pipe B701, and an arc groove 703 is fixedly provided in the middle of the inner channel 702. An outer protective shell C704 is fixedly connected to the middle of one end face of the connecting pipe B701, and a compression spring B705 is connected to the inside of the outer protective shell C704. One end of the compression spring B705 is connected to a hemispherical top block 706, and the hemispherical top block 706 is movably fitted in the arc groove 703.

[0045] The positioning component 4 includes an outer protective shell B401, and a top block 402 is movably penetrated on the end face of the outer protective shell B401 facing the rectangular through hole 502. Both sides of one end of the top block 402 are fixedly connected with a compression spring A404 and a movable column 405. The movable column 405 is located in the compression spring A404. Two sliding frames 403 are arranged and fixedly connected on the upper and lower sides of one end of the top block 402. The end face of one end of the top block 402 and the end face of the outer protective shell B401 away from the top block 402 are connected through the compression spring A404. The movable column 405 penetrates the end face of the outer protective shell B401 away from the top block 402, and a top column 406 is fixedly connected in the middle of one end of the top block 402.

[0046] By being fixedly connected to two L-shaped connecting columns 503 on both sides of the upper end of the top block 402, the top column 406 extends through the middle of the connecting tube B701 to the arc groove 703, and one end face of the top column 406 is in contact with the top movement of the hemispherical top block 706. The lateral movement of the hemispherical top block 706 pushes the hemispherical top block 706 inside the outer protective shell C704. The clamping plate 501 is an inverted L-shape, and a closed enclosure for the construction site is clamped between the vertical end wall inside the clamping plate 501 and the top block 402, so that the overall positioning component 4 is fixed on the closed enclosure for the construction site.

[0047] When the overall positioning component 4 and the clamping component 5 are fixed on the closed enclosure for the construction site, the closed enclosure for the construction site squeezes the top block 402 toward the inside of the top block 402, and the overall top block 402 elastically squeezes the two compression springs A404 in the outer protective shell B401, and the top column 406 at the middle of one end of the top block 402 is inserted into the middle of the connecting pipe B701, and the top column 406 pushes the hemispherical top block 706 inside the arc groove 703 laterally, so that the hemispherical top block 706 is disengaged from the arc groove 703. At this time, the inner channel 702 set through the upper and lower sides of the inside of the connecting pipe B701 is in a through state. This design realizes that when the overall device is fixed, the automatic water valve 7 is opened at the same time, so that the automatic water valve 7 can transport water to the buffer chamber 303 in time.

[0048] When the overall positioning component 4 and the clamping component 5 are disassembled from the closed enclosure for the construction site, the closed enclosure for the construction site no longer presses the top block 402, and the top block 402 no longer presses the extension elastic force of the compression spring A404, so that the top block 402 as a whole moves in the direction of the L-shaped connecting column 503 under the extension elastic force of the two compression springs A404, and the top block 402 drives the top column 406 at one end to be pulled out from the arc groove 703, thereby releasing the top column 406 from pushing the hemispherical top block 706, and the hemispherical top block 706 is compressed by the compression spring B7. The stretching elastic force of 05 pushes the curved surface at one end of the arc groove 703 to move downward, and finally the curved surface of the arc groove 703 fits with the hemispherical top block 706, and the hemispherical top block 706 blocks the middle of the inner channel 702. At this time, the water flow cannot reach the buffer chamber 303 through the connecting pipe A305. Through this design, after the entire device is disassembled, the hemispherical top block 706 inside the automatic water valve 7 blocks the inner channel 702 in time, avoiding the spray head 304 from continuing to spray after the entire device is disassembled, further saving water on the construction site.

[0049] One end of the connecting pipe A305 is fixedly connected to an automatic water valve 7, the lower end of the automatic water valve 7 is fixedly connected to a tee pipe 8, one end of the tee pipe 8 is connected to a water pump via a pipeline, and the water pump is connected to a water tank via a pipeline. The water pump draws water from the water tank, and through the connection between the tee pipe 8 and the automatic water valve 7, the water flows into the connecting pipe A305 through the automatic water valve 7 and the tee pipe 8. The tee pipe 8 on the dust suppression structure has three connectors, one of which is connected to the automatic water valve 7, the other connector on the tee pipe 8 is connected to the water pump via a pipeline, and the tee pipe 8 has another connector that is connected to the connector of the tee pipe 8 on another dust suppression structure. This connection method allows each dust suppression structure to be connected in series through pipelines.

[0050] A dust reduction method for a dust reduction structure for a green construction site, the dust reduction method comprising the following steps:

[0051] Step A: First, push the sliding block 505 between the two C-shaped sliding plates 504. The sliding block 505 drives the L-shaped connecting column 503 and the top block 402 to move inside the external protective shell B401. At this time, the vertical end wall on the inner side of the clamping plate 501 and the top block 402 are clamped on the partition used on the construction site, thereby fixing the entire dust reduction device.

[0052] Step B: Then, the lateral movement of the top block 402 toward the inner end of the outer protective shell B401 drives the top column 406 to move lateral, so that one end of the top column 406 is inserted into the middle of the connecting tube B701, and the top column 406 pushes the hemispherical top block 706 inside the arc groove 703 lateraly.

[0053] Step C: At this time, the hemispherical top block 706 moves laterally into the outer protective shell C704 to squeeze the extension elastic force of the compression spring B705, and the hemispherical top block 706 disengages from the arc groove 703, which makes the arc groove 703 open, allowing the inner channel 702 in the middle of the connecting tube B701 to circulate liquid.

[0054] Step D: Then, one end of the three-way pipe 8 is connected to an external water pump. The water pump draws water from the water tank and allows the water to flow into the buffer chamber 303 through the automatic water valve 7 and the connecting pipe A305. The spray head 304 on one side of the buffer chamber 303 then performs a spray dust reduction operation.

[0055] Step E: The wind blows the fan blades B204 on the rotating column 201, and the fan blades B204 drive the rotating column 201 and the driving shaft 202 to rotate. The rotation of the driving shaft 202 drives the driving gear 205 to rotate. The rotation of the driving gear 205 drives the secondary gear 6 and the driven gear 306 to rotate. The driven gear 306 drives the driven shaft 301, the buffer chamber 303 and the spray head 304 to rotate, so that the entire spray head 304 performs a rotary spray dust reduction operation.

[0056] Step F: After the final use, push the sliding block 505 horizontally into the rectangular through hole 502 again, so that the sliding block 505 drives the top block 402 to press the extension elastic force of the two compression springs A404, thereby releasing the pressure fixation between the top block 402 and the closed enclosure for the construction site, so that the entire device can be removed from the closed enclosure for the construction site.

[0057] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein.
