Description

Technical Field

[0001] This invention relates to the field of dust suppression technology, specifically to a multifunctional integrated foundation treatment and drainage device for parking lot construction. Background Technology

[0002] The stability and safety of a parking lot are mainly determined by its foundation. The bearing capacity of the foundation must be greater than or equal to the weight of the parking lot when it is fully loaded. Therefore, before construction, the foundation needs to be built according to the scale of the entire parking lot. The larger the scale of the parking lot, the greater the bearing capacity required for the foundation, and consequently the deeper the foundation pit needs to be excavated.

[0003] The excavation process damages the surface structure, exposing the soil to the air. This is especially true for the construction of foundation pits in large open-air parking lots, where transport vehicles frequently stir up dust while carrying sand and soil, impacting the construction environment. To ensure construction progress, water mist spraying devices are typically installed at the construction site to absorb dust particles and reduce dust. However, the fixed installation location of these devices limits the spraying range, affecting the dust absorption effect and thus limiting the dust reduction efficiency. Existing technologies offer better solutions to this problem, such as a mining ventilation and water-cooled dust suppression device (patent number CN118959071B). This device includes an air supply pipe and a water supply pipe coaxially arranged inside the air supply pipe. Multiple exhaust pipes are located on the outer wall of the air supply pipe, and multiple drainage pipes extending into the air supply pipe are located on the outer wall of the water supply pipe. Each exhaust pipe has an atomizing component at its end. When in use, it allows for full contact between gas and liquid, increasing atomization and expanding the spray range of the water mist, enabling dust particles to directly contact the water mist and thus improving dust suppression to ensure construction progress. However, the following drawbacks still exist: In cities along large rivers and lakes (such as Wuhan and Wuxi), due to high groundwater levels, groundwater can easily seep into the foundation pit during construction. Therefore, drainage pipes need to be installed to solve the drainage problem within the foundation pit, ensuring its dryness and thus guaranteeing construction progress. However, influenced by lake and land breezes, the wind force above the city is unstable. Dust generated during the construction of foundation pits for large open-air parking lots is affected by wind. Before construction, the impact of maximum wind force on dust needs to be considered to install an appropriate number of water mist spraying devices to ensure dust suppression. However, dust generated by maximum wind force is not continuous. Simultaneously operating multiple water mist spraying devices will waste water resources, and a large amount of water falling into the foundation pit will affect its dryness, also impacting construction progress.

[0004] Therefore, in order to solve the above problems, a multifunctional integrated foundation treatment and drainage device for parking lot construction is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a multifunctional integrated foundation treatment and drainage device for parking lot construction. This device solves the problems of water waste caused by simultaneously operating multiple water mist spraying devices, and the reduction of pit dryness due to large amounts of water falling into the pit, which also affects construction progress. Through interconnected drive, adjustment, and atomizing components, the atomizing component can automatically rotate under the impact of water flow, thereby automatically expanding the water mist spraying range. When wind power is insufficient to drive the atomizing component to rotate faster, water flow is limited to one of the two atomizing nozzles in the atomizing component, thus conserving water resources while ensuring dust suppression and preventing large amounts of water from affecting the pit's dryness. Simultaneously, when the atomizing component is driven to rotate faster by wind, centrifugal force can be used to open the other atomizing nozzle, expanding the water mist spraying range and increasing the water flow rate per unit time, further reducing dust generated by increased wind and ensuring construction progress.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A multifunctional integrated foundation treatment and drainage device for parking lot construction includes a filter tank, a water storage tank, and a circulation pipe. Both ends of the circulation pipe are connected to the water storage tank and are arranged in multiple sections. The filter tank is equipped with a water pumping pipe and a water delivery pipe, and is connected to the water storage tank through the water delivery pipe. It also includes a hollow column, a drive component, an adjustment component, and an atomizing component disposed between two adjacent sections of the circulation pipe. The drive component is disposed on the hollow column. The adjustment component is connected to the drive component. The atomizing component is connected to the adjustment component and rotates with the drive component through the adjustment component. The atomizing component includes two atomizing nozzles. When the water flows in the circulation pipe, it impacts the drive component to rotate and is diverted to one of the atomizing nozzles for spraying. When the wind force drives the adjustment component to rotate faster through the drive component, it drives the two atomizing nozzles away from the hollow column through centrifugal force and opens the other atomizing nozzle.

[0008] Preferably, the drive assembly includes a straight tube, a tapered tube, and fan blades. The straight tube passes through the hollow column, the tapered tube is located at the lower end of the straight tube, and the fan blades are located at the upper end of the straight tube. Two circulation tubes on the hollow column are coaxially arranged, and the axis of the circulation tube is offset from the axis of the hollow column. Multiple drive blades are arranged in a circumferential array on the outer surface of the tapered tube. Drive grooves are formed on the surface of the drive blades, and the depth of the drive grooves increases outward along the radial direction of the hollow column.

[0009] It is known that there are many ways to drive the straight pipe to rotate and cause the atomizing nozzle to revolve around the axis of the hollow column, thereby expanding the water mist spraying range. The conventional method is to use a motor for driving. Considering the actual working scenario, due to the large area of ​​the foundation pit and the large number of hollow columns required, it is necessary to equip each hollow column with a motor, resulting in a high cost for the entire equipment. Therefore, this solution is adopted. Through the set conical pipe and the drive blades set on the outer wall of the conical pipe, the water flow has an impact force during the flow in the circulation pipe. When the water flow impacts the outer wall of the conical pipe, it can drive the conical pipe to rotate, thereby driving the straight pipe to rotate. In turn, the atomizing nozzle can follow the straight pipe to revolve around the axis of the hollow column, thereby automatically expanding the water mist spraying range.

[0010] Preferably, the adjustment assembly includes a fixed frame, a first guide tube and a second guide tube that are sleeved together, a flexible hose, a hollow stop block, a baffle, a corrugated pipe, and an air guiding assembly. The fixed frame is mounted on the straight pipe. One end of the first guide tube is hinged to the fixed frame. One end of the flexible hose is connected to the first guide tube, and the other end extends into the interior of the straight pipe. The stop block is sleeved with the second guide tube. The baffle is sleeved with the second guide tube. The corrugated pipe is positioned between the stop block and the baffle and is sleeved with the second guide tube. The air guiding assembly is mounted on the baffle. When the baffle moves away from the stop block, air enters the interior of the stop block through the air guiding assembly. When the baffle moves closer to the stop block, air inside the stop block enters the corresponding atomizing nozzle through the air guiding assembly.

[0011] It is known that there are many ways to adjust the distance between the atomizing nozzle and the hollow column to change and further alter the water mist spray range. A conventional method involves adjusting the position of the atomizing nozzle using the extension and retraction function of the output end of an electric actuator. However, considering that the nozzle revolves around the axis of the hollow column following the straight pipe, proper installation of the electric actuator cannot be guaranteed. Therefore, this solution is adopted. Through the provided guide pipes one and two, centrifugal force can be used to adjust the insertion depth between guide pipes one and two during the rotation of the straight pipe, thereby adjusting the distance between the atomizing nozzle and the hollow column, and thus further adjusting the water mist spray range.

[0012] Preferably, the atomizing assembly further includes an "I"-shaped tube, a piston, and an L-shaped rod. The "I"-shaped tube is disposed at the end of the guide tube, the two atomizing nozzles are respectively disposed at the ends of the "I"-shaped tube, the piston is disposed inside the "I"-shaped tube, and the two ends of the L-shaped rod are respectively connected to the stop block and the piston.

[0013] By adopting the above scheme, when the driving force of the wind on the fan blades is greater than the impact force of the water flow, causing the fan blades to accelerate, the second guide pipe will move away from the hollow column. At this time, under the action of the L-shaped rod, the piston can move from the inside of the "I"-shaped tube outward, so that the piston is misaligned with the flow channel of the vertical section of the "I"-shaped tube, allowing the water flow to enter the inside of another atomizing nozzle and be sprayed out from that atomizing nozzle, thereby increasing the amount of water mist sprayed, reducing water waste while ensuring the dust suppression effect.

[0014] Preferably, the gas guiding assembly includes a second piston, an L-shaped tube, a first one-way valve, and a second one-way valve. The second piston is disposed inside the baffle and is sleeved with the guide tube. The L-shaped tube passes through the baffle and the baffle plate, and its two ends are sleeved with the second piston and the second guide tube, respectively. The first one-way valve is disposed on the L-shaped tube, and the second one-way valve is disposed on the baffle.

[0015] By adopting the above scheme, the one-way conduction function of one-way valve one and one-way valve two can be achieved. When the wind force increases, causing the fan blade speed to increase and the atomizing nozzle to move away from the hollow column, air is drawn into the interior of the baffle for storage. When the wind force decreases, causing the fan blade speed to decrease and the atomizing nozzle to return to the hollow column, the air stored inside the baffle is pressed into the interior of the corresponding atomizing nozzle. This improves the atomization effect by utilizing the process of air being sprayed out from the atomizing nozzle. This achieves further improvement in dust suppression effect while maintaining the dust level even when the wind force decreases, thus ensuring the construction progress. To prevent dust from clogging one-way valve two, a filter screen can be installed on the surface of the baffle to filter the air entering one-way valve two. This is a conventional technical solution, so it has not been described in detail.

[0016] Preferably, the fan blade includes a fixed block and a plurality of V-shaped blades arranged in a circumferential array on the fixed block. The fixed block is disposed on a straight pipe, and the opening direction of the V-shaped blades is opposite to the rotation direction of the straight pipe.

[0017] By adopting the above scheme and utilizing the V-shaped blades, the air resistance encountered when water flows impact the conical tube and drives the conical tube to rotate can be reduced. When the wind force increases, the opening of the V-shaped blades can be used to increase the wind resistance, thereby automatically increasing the speed of the fan blades.

[0018] Preferably, a spring is provided between the block and the baffle, and the spring is sleeved with the bellows. The length of the spring remains constant when the wind force does not reach the set value.

[0019] By adopting the above scheme, under the elastic force of the spring, when the wind force decreases and the fan blade speed decreases (i.e., the centrifugal force generated during rotation decreases), the atomizing nozzle can be pulled back by the spring, thereby achieving the re-blocking of one of the atomizing nozzles, reducing the water flow rate sprayed per unit time. This ensures the dust suppression effect while avoiding the waste of water resources and also prevents the water from affecting the dryness of the foundation pit after it falls, thus ensuring the construction progress.

[0020] Preferably, when the spring is not deformed, the piston is located at the middle of the upper end of the "I"-shaped tube, and the length of the piston is greater than the diameter of the "I"-shaped tube.

[0021] By adopting the above scheme, when the wind force is insufficient to drive the fan blades to rotate faster, the spring force can overcome the pressure of the water flow in the second guide pipe and the centrifugal force generated when the water flow impacts the rotating conical tube, preventing the water flow from being sprayed out of the upper atomizing nozzle. When the dust level is low, the water flow rate sprayed per unit time is reduced, thus ensuring the dust suppression effect while avoiding the waste of water resources and affecting the dryness of the foundation pit, thereby ensuring the construction progress of the foundation pit. When the wind force increases to the point of driving the fan blades to rotate faster, the pressure of the water flow in the second guide pipe and the centrifugal force generated when the water flow impacts the rotating conical tube can overcome the spring force, causing the two atomizing nozzles to move away from the hollow column, driving the piston one to misalign with the vertical section of the "I" shaped tube, thereby increasing the water flow rate sprayed per unit time, thus ensuring the dust suppression effect and further ensuring the construction progress.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. Through the installation of a conical tube, a straight tube, an adjusting component, and an atomizing component, on the one hand, when the water flows in the circulation pipe, the impact force generated by the water flow can drive the conical tube to rotate the straight tube. The conical tube can also guide some water, allowing it to enter the atomizing component and then be sprayed out. Furthermore, the rotation of the straight tube automatically expands the spray range of the water mist, thereby increasing the dust suppression area and improving the dust suppression effect. On the other hand, the centrifugal force generated when the water flow drives the conical tube to rotate the straight tube is insufficient to overcome the spring force in the adjusting component, limiting the water flow rate sprayed by the atomizing component per unit time. This allows for maintaining dust suppression effectiveness while reducing water consumption under normal dust levels, thus saving water resources and preventing large amounts of water from affecting the dryness of the foundation pit and impacting construction progress.

[0024] 2. Through the design of the V-shaped blades, springs, L-shaped rods, and piston one, when the rotational speed of the V-shaped blades driven by wind is greater than the rotational speed of the conical tube driven by the impact force of water flow, the guide pipe one will accelerate and rotate along with the straight pipe through the fixed frame. During the acceleration rotation, the centrifugal force generated will overcome the elastic force of the spring, causing the atomizing nozzles to move upward and away from the straight pipe, further expanding the spray range of the water mist. Furthermore, under the connection of the L-shaped rod, the stop block, and piston one, the movement of piston one is restricted, causing piston one to be misaligned with the upper end of the vertical section of the "I"-shaped tube. This allows water to be sprayed from both atomizing nozzles simultaneously, thus ensuring dust suppression when increased wind force leads to heavier dust, effectively guaranteeing the construction progress.

[0025] 3. Through the set piston two, L-shaped tube, one-way valve one, and one-way valve two, when the centrifugal force generated by rotation overcomes the elastic force of the spring, the guide pipe will drive the baffle away from the block. Thus, under the action of the L-shaped tube, piston two, and one-way valve two, external air can be drawn into the interior of the block for storage. When the centrifugal force generated by rotation decreases and the baffle moves closer to the block, the air inside the block can enter the interior of the guide pipe two through the L-shaped tube and one-way valve one. With the dynamic changes of wind force, the L-shaped tube, one-way valve one, and one-way valve two can continuously deliver air into the interior of the guide pipe two, so that the air follows the flow of water and is sprayed out from the corresponding atomizing nozzle, thereby improving the atomization effect of the atomizing nozzle, thus improving the dust suppression effect and further ensuring the construction progress.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figures 1 to 8 This invention provides a multifunctional integrated foundation treatment and drainage device for parking lot construction, the technical solution of which is as follows:

[0037] For details, please refer to Figure 1 A multifunctional foundation treatment and drainage integrated device for parking lot construction includes a filter tank 1, a water storage tank 2, and a circulation pipe 3. Both ends of the circulation pipe 3 are connected to the water storage tank 2 and are arranged in multiple sections. The filter tank 1 is equipped with a pumping pipe 11 and a water delivery pipe 12, and is connected to the water storage tank 2 through the water delivery pipe 12. Due to the high groundwater level in cities along large rivers and lakes, and the deep excavation depth of the foundation pit of large parking lots, groundwater can easily seep into the interior of the pit and affect the normal construction of the pit. By using the pumping pipe 11, water inside the pit can be pumped into the filter tank 1, and after filtration, it can be transported to the interior of the water storage tank 2 through the water delivery pipe 12 for storage, so as to facilitate subsequent dust suppression, thereby realizing comprehensive resource utilization.

[0038] As one embodiment of the present invention, refer to Figure 1 , Figure 2 , Figure 3 and Figure 6It also includes a hollow column 4, a drive assembly 5, an adjustment assembly 6, and an atomizing assembly 7 disposed between two adjacent circulation pipes 3. The drive assembly 5 is disposed on the hollow column 4 and includes a straight pipe 51, a tapered pipe 52, and a fan blade 53. The straight pipe 51 passes through the hollow column 4, the tapered pipe 52 is disposed at the lower end of the straight pipe 51, and the fan blade 53 is disposed at the upper end of the straight pipe 51. The two circulation pipes 3 on the hollow column 4 are coaxially disposed, and the axis of the circulation pipe 3 is offset from the axis of the hollow column 4. The outer surface of the tapered pipe 52 has a circumferential array of multiple drive blades 521. The surface of the drive blades 521 is provided with drive grooves 522, and the depth of the drive grooves 522 increases outward along the radial direction of the hollow column 4. The fan blade 53 includes a fixing block 531 and a circumferential array of multiple V-shaped blades 532 disposed on the fixing block 531. The fixing block 531 is disposed on the straight pipe 51, and the opening direction of the V-shaped blades 532 is opposite to the rotation direction of the straight pipe 51.

[0039] Under the above conditions, after the water flows into the hollow column 4 through the circulation pipe 3, it directly impacts the drive groove 522 on the drive blade 521. Under the impact of the water flow, the drive blade 521 drives the conical tube 52 to rotate. Since the conical tube 52 is connected to the straight pipe 51 and the fan blade 53 in sequence, the rotation of the conical tube 52 drives the straight pipe 51 and the fan blade 53 to rotate. During the rotation of the fan blade 53, the opening design of the V-shaped blade 532 can reduce the wind resistance encountered by the water flow impacting the conical tube 52 during rotation. Then, under the action of the adjustment component 6, the atomizing component 7 is driven to rotate around the axis of the hollow column 4, thereby expanding the water mist spraying range and improving the dust suppression effect to ensure the construction progress.

[0040] As one embodiment of the present invention, refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 and Figure 8 The adjusting component 6 is connected to the driving component 5. The adjusting component 6 includes a fixed frame 61, a first guide tube 62 and a second guide tube 63 that are sleeved together, a hose 64, a hollow stop block 65, a baffle 66, a corrugated pipe 67, and an air guiding component 68. The fixed frame 61 is set on the straight pipe 51. One end of the first guide tube 62 is hinged to the fixed frame 61. One end of the hose 64 is connected to the first guide tube 62, and the other end extends into the interior of the straight pipe 51. The stop block 65 is sleeved with the first guide tube 62. The baffle 66 is sleeved with the second guide tube 63. The corrugated pipe 67 is set between the stop block 65 and the baffle 66 and is sleeved with the second guide tube 63.

[0041] Under the above-mentioned conditions, the rotation of the straight pipe 51 drives the rotation of the fixed frame 61, which in turn drives the rotation of the first guide pipe 62. Since the first guide pipe 62 is sleeved with the second guide pipe 63, the second guide pipe 63 will rotate around the axis of the hollow column 4 along with the first guide pipe 62. Since the tapered pipe 52 is connected to the straight pipe 51, and the straight pipe 51 is connected to the first guide pipe 62 through the hose 64, the water will flow through the tapered pipe 52, the straight pipe 51 and the hose 64 in sequence before entering the interior of the first guide pipe 62 and the second guide pipe 63, and finally be sprayed out from the atomizing component 7 in the form of water mist. After the water enters the interior of the first guide pipe 62 and the second guide pipe 63, it can be sealed by the connection of the corrugated pipe 67 with the baffle 65 and the baffle 66 to prevent water leakage, so that all the water entering the interior of the first guide pipe 62 can be sprayed out from the atomizing component 7.

[0042] As one embodiment of the present invention, refer to Figure 1 , Figure 4 , Figure 5 , Figure 7 and Figure 8 The atomizing component 7 is connected to the adjusting component 6. The atomizing component 7 includes two atomizing nozzles 71, as well as an "I"-shaped tube 72, a piston 73, and an L-shaped rod 74. The "I"-shaped tube 72 is located at the end of the guide tube 63. The two atomizing nozzles 71 are respectively located at the ends of the "I"-shaped tube 72. The piston 73 is located inside the "I"-shaped tube 72. The two ends of the L-shaped rod 74 are respectively connected to the stop block 65 and the piston 73.

[0043] Under the above-mentioned conditions, when the wind force is insufficient to drive the V-shaped blade 532 to accelerate the rotation of the straight pipe 51 (i.e., the single atomizing nozzle 71 can handle dust when working normally), the piston 73 is always blocked directly above the vertical section of the "I"-shaped pipe 72, thereby limiting the water flow rate sprayed per unit time. This ensures the dust control effect while avoiding the waste of water resources, and also avoids the situation where the water flow rate per unit time is too large, which would reduce the dryness of the foundation pit, thus effectively ensuring the construction progress.

[0044] As one embodiment of the present invention, refer to Figure 4 , Figure 5 , Figure 7 and Figure 8 The air guiding assembly 68 is disposed on the baffle 66. The air guiding assembly 68 includes a second piston 681, an L-shaped tube 682, a first check valve 683, and a second check valve 684. The second piston 681 is disposed inside the baffle 65 and is sleeved with the first guide tube 62. The L-shaped tube 682 is disposed through the baffle 65 and the baffle 66, and its two ends are sleeved with the second piston 681 and the second guide tube 63, respectively. The first check valve 683 is disposed on the L-shaped tube 682, and the second check valve 684 is disposed on the baffle 65.

[0045] Under the aforementioned conditions, when the wind force increases and drives the V-shaped blades 532 to accelerate the rotation of the straight pipe 51 (i.e., the dust level increases to the point where the water flow rate sprayed by a single atomizing nozzle 71 is insufficient to guarantee the dust suppression effect), under the action of centrifugal force, the "I"-shaped pipe 72 and the two atomizing nozzles 71 will move away from the hollow column 4. During this process, since the two ends of the L-shaped rod 74 are respectively connected to the baffle 65 and the piston 73, and the baffle 65 is fixedly set on the guide pipe 62, the "I"-shaped pipe 72 will move relative to the piston 73 as it moves away from the hollow column 4, causing the piston to... The upper end of the vertical section of the piston 73 is misaligned with the upper end of the vertical section of the "I"-shaped pipe 72, allowing water to enter the interior of the upper atomizing nozzle 71 and eventually be sprayed out from the atomizing nozzle 71, thereby increasing the water flow rate per unit time. Furthermore, the faster the wind-driven straight pipe 51 rotates, the smaller the blocking range of the piston 73 on the upper end of the vertical section of the "I"-shaped pipe 72 becomes, until the guide pipe 62 and the guide pipe 63 are in a horizontal state. That is, the greater the dust, the greater the water flow rate sprayed per unit time, thus ensuring the construction progress while guaranteeing the dust suppression effect.

[0046] As one embodiment of the present invention, refer to Figure 4 , Figure 5 , Figure 7 and Figure 8 A spring 69 is provided between the baffle 65 and the baffle 66. The spring 69 is sleeved with the bellows 67. When the wind force does not reach the set value (the set value is the critical value at which the wind force drives the V-shaped blade 532 to drive the straight pipe 51 to start accelerating), the length of the spring 69 remains constant. That is, the length of the spring 69 will not change when only water drives the conical pipe 52 to drive the straight pipe 51 to rotate during the flow of water inside the circulation pipe 3. When the spring 69 is not deformed, the piston 73 is located at the middle of the upper end of the "I"-shaped pipe 72. The length of the piston 73 is greater than the diameter of the "I"-shaped pipe 72.

[0047] Under the aforementioned conditions, on the one hand, when the wind force increases to the point that the straight pipe 51 accelerates its rotation, under the action of centrifugal force, the second guide pipe 63 will move away from the first guide pipe 62, thus stretching the spring 69 under the action of the baffle 65 and the baffle 66. When the wind force decreases to the point that it is insufficient to drive the straight pipe 51 to accelerate its rotation, the spring 69 overcomes the centrifugal force and resets, that is, it drives the second guide pipe 63 to move closer to the first guide pipe 62. In the process of the second guide pipe 63 moving closer to the first guide pipe 62, it can drive the "I" shaped pipe 72 to move synchronously, so that the piston 73 resets to block the upper end of the vertical section of the "I" shaped pipe 72, thereby reducing the water flow rate sprayed per unit time. While ensuring the dust suppression effect, it can save water resources and avoid affecting the dryness of the foundation pit, thus ensuring the construction progress. On the other hand, as can be seen from the above, when the wind force increases and the second guide pipe 63 moves away from the first guide pipe 62, the spring 69 will be stretched by the baffle 65 and the baffle 66. When the baffle 66 moves away from the first guide pipe 62, it moves along with the second guide pipe 63. During the movement of the baffle 66, it can drive the L-shaped pipe 682 to move. During the movement of the L-shaped pipe 682, the one-way valve 684 can draw the outside air into the baffle block 65 for storage. When the wind force decreases and the spring 69 pulls the baffle 66 closer to the baffle block 65, the air stored in the baffle block 65 will enter the L-shaped pipe 682 under the action of the one-way valve 683, and be sprayed out from the corresponding atomizing nozzle 71 through the second guide pipe 63 and the "I" shaped pipe 72. That is, under the premise that the wind force drives the V-shaped blade 532 to drive the straight pipe 51 to rotate faster, when the wind force changes dynamically, the piston 681 moves back and forth, which can continuously deliver air into the second guide pipe 63, thereby improving the atomization effect of the atomizing nozzle 71, further ensuring the dust reduction effect, and further ensuring the construction progress.

[0048] Working principle:

[0049] Each hollow column 4 is fixedly installed in a designated position. Water pumps and water pipes 11 are used to pump water that is not discharged from the foundation pit into the filter bucket 1 for filtration. The filtered water is transported to the water storage tank 2 through the water delivery pipe 12. When dust suppression is required, water pumps can be used to pump water to achieve water circulation in the circulation pipe 3. Since water pumping is a conventional technical means, it will not be described in detail.

[0050] When water flows inside the circulation pipe 3 and enters the corresponding hollow column 4, the water flow directly acts on the drive groove 522 on the drive blade 521, thereby driving the tapered pipe 52 to rotate under the impact force of the water flow. Since the tapered pipe 52 is connected to the straight pipe 51, the rotation of the tapered pipe 52 drives the straight pipe 51 to rotate, and the rotation of the straight pipe 51 drives the fixed frame 61 installed on the straight pipe 51 to rotate. Since the first guide pipe 62 is hinged to the fixed frame 61 and connected to the inside of the straight pipe 51 through the hose 64, and the second guide pipe 63 is sleeved with the first guide pipe 62, and the outer walls of the first guide pipe 62 and the second guide pipe 63 are jointly sleeved with a corrugated pipe 67 to prevent water leakage. Therefore, some of the water entering the hollow column 4 can enter the interior of the second guide pipe 63 through the conical pipe 52, straight pipe 51, hose 64 and guide pipe 1 62. Since the first guide pipe 62 is equipped with a baffle 65 and the second guide pipe 63 is equipped with a baffle 66, and a spring 69 is installed between the baffle 65 and the baffle 66, the second guide pipe 63 will rotate with the straight pipe 51 and drive the "I" shaped pipe 72 and the two atomizing nozzles 71 installed on it to rotate. During the rotation, the water inside the second guide pipe 63 can pass through the "I" shaped pipe 72 and be sprayed out from the atomizing nozzles 71 below, thereby automatically expanding the spray range of the water mist under the impact of the water flow.

[0051] Since the upper end of the straight pipe 51 is equipped with a fixed block 531 and a V-shaped blade 532, when the wind force is insufficient to drive the V-shaped blade 532 to accelerate the rotation of the straight pipe 51, refer to Figure 2 , Figure 4 and Figure 5 When the straight pipe 51 rotates under the impact of the water flow, the centrifugal force generated is insufficient to overcome the elastic force of the spring 69. Therefore, the distance between the stop block 65 and the baffle 66 will not change. That is, the "I"-shaped pipe 72 and its internal piston 73 remain relatively stationary. In other words, the piston 73 is always blocked at the upper end of the vertical section of the "I"-shaped pipe 72, preventing water from being sprayed out from the atomizing nozzle 71 above. This ensures dust suppression effect and avoids water waste when the wind is weak, and also prevents the dryness of the pit from being reduced due to excessive water use for dust suppression. When the wind drives the V-shaped blade 532 to accelerate the rotation of the straight pipe 51, refer to Figure 6 , Figure 7 and Figure 8The centrifugal force generated during the rotation of the straight pipe 51 increases and can overcome the elastic force of the spring 69, causing the second guide pipe 63 to move away from the baffle 65 under the action of centrifugal force. Since the two ends of the L-shaped rod 74 are fixedly connected to the baffle 65 and the piston 73 respectively, and the piston 73 is movably set inside the "I"-shaped tube 72, the L-shaped rod 74 can pull the piston 73 during the process of the baffle 66 moving away from the baffle 65, so that the piston 73 and the "I"-shaped tube 72 are relatively displaced, that is, the piston 73 and the upper end of the vertical section of the "I"-shaped tube 72 are misaligned. Therefore, the water flow can be sprayed out from the two atomizing nozzles 71 at the same time, thereby increasing the amount of water sprayed per unit time, which can improve the dust suppression effect when the wind increases and dust increases, and further ensure the construction progress.

[0052] Reference Figure 5 and Figure 8 Because a piston 681 is installed inside the baffle 65, and an L-shaped tube 682 is installed between the piston 681 and the baffle 66, and the L-shaped tube 682 is movably connected to the baffle 65, the piston 681 can move inside the baffle 65 through the L-shaped tube 682 as the baffle 66 moves away from the baffle 65. Since a one-way valve 683 is installed on the L-shaped tube 682 and a one-way valve 684 is installed on the baffle 65, external air is drawn into the baffle 65 and stored inside the baffle 65 during the movement of the piston 681. When the wind force decreases... Spring 69 contracts and drives baffle 66 to approach block 65. Air stored inside block 65 enters the interior of guide pipe 63 through L-shaped pipe 682 and one-way valve 683. Since the wind force is constantly changing, piston 681 moves irregularly back and forth inside block 65, thus continuously supplying external air into guide pipe 63. After passing through I-shaped pipe 72, the air is sprayed out from the corresponding atomizing nozzle 71, thereby improving the atomization effect of atomizing nozzle 71, ensuring dust suppression effect, and further ensuring construction progress.
