Description

Technical Field

[0001] The present invention relates to the technical field of dust reduction, and specifically to a multifunctional foundation treatment and drainage integrated device for parking lot construction. Background Art

[0002] The stability and safety of a parking lot are mainly determined by the foundation. The bearing capacity of the foundation must be greater than or equal to the gravity when the parking lot is fully loaded. Therefore, before the construction of the parking lot, a corresponding 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 thus the deeper the foundation pit that needs to be excavated.

[0003] During the process of excavating the foundation, the surface structure will be damaged, exposing the soil to the air. Especially during the foundation pit construction of large open-air parking lots, when transport vehicles frequently transport sand, gravel, and soil at the construction site, dust will be raised, affecting the construction environment. To ensure the construction progress, a water mist spraying device is usually installed at the construction site to adsorb dust particles with water mist, thereby achieving the effect of dust reduction. However, due to the fixed installation position of the water mist spraying device, the spraying range of the water mist is limited, affecting the adsorption effect of the water mist on the dust, and thus limiting the dust reduction effect. For the above solution, there is already a good solution in the prior art. For example, a mine-use air-water combined dust reduction device with the patent number CN118959071B includes an air supply pipe and a water supply pipe coaxially arranged inside the air supply pipe. There are multiple exhaust pipes arranged on the outer wall of the air supply pipe, and multiple drain pipes extending into the air supply pipe are arranged on the outer wall of the water supply pipe. Each exhaust pipe end is provided with an atomization component. When in use, it can make the gas and liquid fully contact, expand the spraying range of the water mist while improving the atomization degree, and enable the dust particles to directly contact the water mist, thereby improving the dust reduction effect to ensure the construction progress. However, there are still the following defects: In cities along large rivers and lakes (such as Wuhan, Wuxi, etc.), due to the high groundwater level, groundwater is likely to seep into the foundation pit during the foundation pit construction process. Therefore, it is necessary to install drainage pipes to solve the drainage problem in the foundation pit to ensure the dryness of the foundation pit and thus ensure the construction progress. However, affected by the lake-land breeze, the wind factors above the city are unstable. Since the dust raised during the foundation pit construction of large open-air parking lots is affected by the wind, the impact of the maximum wind force on the dust needs to be considered before construction to install an appropriate number of water mist spraying devices to ensure the dust reduction effect. However, the dust caused by the maximum wind force is not always continuous. By simultaneously turning on multiple water mist spraying devices, it will cause waste of water resources, and a large amount of water falling into the foundation pit will affect the dryness of the foundation pit and also affect the construction progress.

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

[0005] The object of the present invention is to provide a multifunctional foundation treatment and drainage integration device for parking lot construction, which solves the problems that the simultaneous opening of multiple water mist spraying devices will cause waste of water resources, and a large amount of water falling into the foundation pit will reduce the dryness of the foundation pit and also affect the construction progress. By providing a connected driving component, adjusting component and atomizing component, the automatic rotation of the atomizing component can be realized under the action of water flow impact, so as to automatically expand the water mist spraying range. And when the wind force is not enough to drive the atomizing component to rotate at an accelerated speed, the water flow is restricted to only spray out from one of the two atomizing nozzles in the atomizing component, so as to save water resources while ensuring the dust reduction effect and avoid the influence of a large amount of water falling on the dryness of the foundation pit. At the same time, when the wind force drives the atomizing component to rotate at an accelerated speed, the other atomizing nozzle can be opened by the action of centrifugal force, and while expanding the water mist spraying range, the water flow rate sprayed out per unit time can be increased, so as to further reduce the dust caused by the increase of wind force and then ensure the construction progress.

[0006] To achieve the above object, the present invention provides the following technical solutions: A multifunctional foundation treatment and drainage integration device for parking lot construction, including a filter barrel, a water storage barrel and a circulation pipe. Both ends of the circulation pipe are connected to the water storage barrel and are arranged in multiple sections. A water suction pipe and a water supply pipe are provided on the filter barrel and are connected to the water storage barrel through the water supply pipe. It also includes a hollow column, a driving component, an adjusting component and an atomizing component arranged between adjacent two sections of the circulation pipe. The driving component is arranged on the hollow column, the adjusting component is connected to the driving component, and the atomizing component is connected to the adjusting component and rotates with the driving component through the adjusting component. The atomizing component includes two atomizing nozzles. When the water flow circulates in the circulation pipe, it impacts the driving component to rotate and is split to spray out from one of the atomizing nozzles. When the wind force drives the adjusting component to rotate at an accelerated speed through the driving component, the two atomizing nozzles are driven away from the hollow column by centrifugal force and the other atomizing nozzle is opened.

[0007] Preferably, the driving component includes a straight pipe, a conical pipe and fan blades. The straight pipe penetrates through the hollow column. The conical pipe is arranged at the lower end of the straight pipe. The fan blades are arranged at the upper end of the straight pipe. The two sections of the circulation pipe on the hollow column are coaxially arranged. The axis of the circulation pipe is arranged offset from the axis of the hollow column. A plurality of driving blades are circumferentially arrayed on the outer surface of the conical pipe. Driving grooves are formed on the surface of the driving blades, and the depth of the driving grooves increases outward along the radial direction of the hollow column.

[0008] It can be seen that there are many ways to drive the straight pipe to rotate and drive the atomizing nozzle to revolve around the axis of the hollow column as the rotation axis, thereby expanding the water mist spraying range. The conventional method is to drive by a motor. Considering the actual working scenario, since the foundation pit area is large and a large number of hollow columns need to be installed, a motor needs to be equipped on each hollow column, resulting in a high cost of the entire device. Therefore, this solution is adopted. By providing a conical pipe and driving blades provided on the outer wall of the conical pipe, since the water flow has an impact force during the process of flowing in the circulation pipe, when the water flow impacts on the outer wall of the conical pipe, it can drive the conical pipe to rotate, thereby driving the straight pipe to rotate, and further driving the atomizing nozzle to be able to revolve around the axis of the hollow column as the rotation axis with the straight pipe, thereby automatically expanding the water mist spraying range.

[0009] Preferably, the adjusting assembly includes a fixing frame, a first guide pipe and a second guide pipe sleeved, a hose, a block provided with a hollow interior, a baffle plate, a corrugated pipe and a gas guiding assembly. The fixing frame is arranged on the straight pipe. One end of the first guide pipe is hinged to the fixing frame. One end of the hose is connected to the first guide pipe, and the other end penetrates into the interior of the straight pipe. The block is sleeved with the first guide pipe. The baffle plate is sleeved with the second guide pipe. The corrugated pipe is arranged between the block and the baffle plate and is sleeved with the second guide pipe. The gas guiding assembly is arranged on the baffle plate. When the baffle plate is far away from the block, air enters the interior of the block through the gas guiding assembly. When the baffle plate is close to the block, the air in the interior of the block enters the corresponding atomizing nozzle through the gas guiding assembly.

[0010] It can be seen that there are many ways to adjust the distance between the atomizing nozzle and the hollow column to further change the water mist spraying range. The conventional method can adjust the position of the atomizing nozzle through the telescopic function of the output end of the electric push rod. Considering that the nozzle revolves around the axis of the hollow column as the rotation axis with the straight pipe, it is impossible to ensure the normal installation of the electric push rod. Therefore, this solution is adopted. By providing the first guide pipe and the second guide pipe, the insertion depth between the first guide pipe and the second guide pipe can be adjusted by using the centrifugal force during the rotation of the straight pipe, so as to adjust the distance between the atomizing nozzle and the hollow column, and further achieve the effect of further adjusting the water mist spraying range.

[0011] Preferably, the atomizing assembly further includes an "I"-shaped pipe, a first piston and an L-shaped rod. The "I"-shaped pipe is arranged at the end of the second guide pipe. The two atomizing nozzles are respectively arranged at the ends of the "I"-shaped pipe. The first piston is arranged inside the "I"-shaped pipe. The two ends of the L-shaped rod are respectively connected to the block and the first piston.

[0012] 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 rotate faster, the second diversion pipe will move away from the hollow column. At this time, under the action of the L-shaped rod, the first piston can be moved outward from the inside of the "I"-shaped pipe, so that the first piston is misaligned with the flow channel of the vertical section of the "I"-shaped pipe, enabling the water flow to enter the inside of another atomizing nozzle and spray out from the atomizing nozzle, thereby increasing the amount of water mist sprayed, reducing water resource waste, and ensuring the dust suppression effect at the same time.

[0013] Preferably, the air guiding assembly includes a second piston, an L-shaped pipe, a first one-way valve and a second one-way valve. The second piston is arranged inside the stop block and sleeved with the first diversion pipe. The L-shaped pipe penetrates through the stop block and the baffle, and its two ends are respectively sleeved with the second piston and the second diversion pipe. The first one-way valve is arranged on the L-shaped pipe, and the second one-way valve is arranged on the stop block.

[0014] By adopting the above scheme, due to the one-way conduction of the first one-way valve and the second one-way valve, when the wind force increases, causing the rotation speed of the fan blades to increase and the atomizing nozzle to move away from the hollow column, air can be pumped into the inside of the stop block for storage. When the wind force decreases, causing the rotation speed of the fan blades to decrease and the atomizing nozzle to reset and approach the hollow column, the air stored inside the stop block can be pressed into the corresponding atomizing nozzle, thereby improving the atomizing effect by using the process of air spraying out from the atomizing nozzle. On the premise that the dust level remains unchanged at the moment when the wind force decreases, the dust suppression effect is further improved, thus ensuring the construction progress. In order to prevent dust from blocking the second one-way valve, a filter screen can be installed on the surface of the stop block to filter the air entering the second one-way valve. This is a conventional technical solution, so it will not be elaborated too much here.

[0015] Preferably, the fan blades include a fixed block and a plurality of V-shaped blades arranged in a circumferential array on the fixed block. The fixed block is arranged on the straight pipe, and the opening directions of the V-shaped blades are opposite to the rotation direction of the straight pipe.

[0016] By adopting the above scheme, with the arrangement of the V-shaped blades, the air resistance when the water flow impacts the conical pipe and drives the conical pipe to rotate can be reduced. When the wind force increases, the wind resistance can be increased by using the openings of the V-shaped blades, thereby automatically accelerating the rotation speed of the fan blades.

[0017] Preferably, a spring is arranged between the stop block and the baffle, and the spring is sleeved with the corrugated pipe. When the wind force does not reach the set value, the length of the spring remains constant.

[0018] By adopting the above scheme, under the elastic force of the spring, when the wind force decreases and causes the rotation speed of the fan blades to decrease (i.e., the centrifugal force generated during rotation decreases), the atomizing nozzle can be pulled back by the spring, so as to realize the re-blocking of one of the atomizing nozzles, reduce the water flow rate sprayed per unit time, avoid wasting water resources while ensuring the dust suppression effect, and also avoid affecting the dryness of the foundation pit after the water falls, thereby ensuring the construction progress.

[0019] Preferably, when the spring is not deformed, the first piston is located at the middle position of the upper end of the "I"-shaped pipe, and the length of the first piston is greater than the diameter of the "I"-shaped pipe.

[0020] By adopting the above scheme, when the wind force is not sufficient to drive the fan blades to rotate at an accelerated speed, the elastic force of the spring can overcome the pressure of the water flow in the second diversion pipe and the centrifugal force generated when the water flow impacts the conical pipe to rotate, avoiding the water flow from spraying out of the upper atomizing nozzle, reducing the water flow rate sprayed per unit time when the dust generation level is relatively low, thereby avoiding wasting water resources and affecting the dryness of the foundation pit while ensuring the dust suppression effect, and further ensuring the foundation pit construction progress. When the wind force increases to drive the fan blades to rotate at an accelerated speed, the pressure of the water flow in the second diversion pipe and the centrifugal force generated when the water flow impacts the conical pipe to rotate can overcome the elastic force of the spring, causing the two atomizing nozzles to move away from the hollow column and driving the first piston to be misaligned with the vertical section of the "I"-shaped pipe during the process, thereby increasing the water flow rate sprayed per unit time, and further ensuring the dust suppression effect and further ensuring the construction progress.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By providing the conical pipe, straight pipe, adjustment assembly and atomization assembly, on the one hand, when the water flow circulates in the circulation pipe, the impact force generated by the water flow can be used to drive the conical pipe to drive the straight pipe to rotate, and the conical pipe can be used to divert part of the water, so that the water flow can enter the atomization assembly and then spray out from the atomization assembly, and the spraying range of the water mist can be automatically expanded as the straight pipe rotates, thereby expanding the dust suppression range and improving the dust suppression effect; on the other hand, the centrifugal force generated when the impact force of the water flow drives the conical pipe to drive the straight pipe to rotate is not sufficient to overcome the elastic force of the spring in the adjustment assembly, which can limit the water flow rate sprayed by the atomization assembly per unit time, so that the dust suppression effect can be ensured while the dust is at a conventional level and the water consumption can be reduced, that is, while saving water resources, it can avoid a large amount of water falling and affecting the dryness of the foundation pit and affecting the construction progress.

[0022] 2. By means of the provided V-shaped blades, springs, L-shaped rods and piston 1, when the rotational speed of the V-shaped blades driven by wind power is greater than the rotational speed of the conical tube driven by the water flow impact force, the guide pipe 1 will accelerate the rotation following the straight pipe through the fixed frame. Moreover, the centrifugal force generated during the acceleration rotation will overcome the elastic force of the spring, causing the atomizing nozzle to move upward and away from the straight pipe, further expanding the spraying range of the water mist. And under the connection action of the L-shaped rod with the stopper and piston 1, the movement of piston 1 can be restricted, making piston 1 misaligned with the upper port of the vertical section of the "I"-shaped pipe, so that the water flow can be ejected from the two atomizing nozzles simultaneously. Thus, when the wind power increases and the dust pollution becomes more serious, the dust suppression effect can be ensured, effectively guaranteeing the construction progress.

[0023] 3. By means of the provided piston 2, L-shaped pipe, check valve 1 and check valve 2, when the centrifugal force generated by rotation overcomes the elastic force of the spring, the guide pipe will drive the baffle away from the stopper, so that the external air can be pumped into the interior of the stopper for storage under the action of the L-shaped pipe, piston 2 and check valve 2. And when the centrifugal force generated by rotation decreases and the baffle approaches the stopper, the air inside the stopper can enter the interior of the guide pipe 2 through the L-shaped pipe and check valve 1. Along with the dynamic change of the wind power, the air can be continuously transported into the interior of the guide pipe 2 by means of the L-shaped pipe, check valve 1 and check valve 2, so that the air can be ejected from the corresponding atomizing nozzle following the flow of the water flow, thereby improving the atomizing effect of the atomizing nozzle, and further improving the dust suppression effect, further guaranteeing the construction progress.

Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1 to 8 , the present invention provides a multifunctional foundation treatment and drainage integration device for parking lot construction, and the technical solutions are as follows: Specifically, please refer to Figure 1 , a multifunctional foundation treatment and drainage integration device for parking lot construction, including a filter barrel 1, a water storage barrel 2 and a circulation pipe 3. Both ends of the circulation pipe 3 are connected to the water storage barrel 2 and are arranged in multiple sections. A water suction pipe 11 and a water delivery pipe 12 are provided on the filter barrel 1 and are connected to the water storage barrel 2 through the water delivery pipe 12. Since the groundwater level in cities along large rivers and lakes is relatively high, and the excavation depth of the foundation pit of a large parking lot is relatively deep, groundwater is likely to seep into the interior of the foundation pit and affect the normal construction of the foundation pit. By using the provided water suction pipe 11, the water in the foundation pit can be pumped into the interior of the filter barrel 1, and after filtration, it can be transported to the interior of the water storage barrel 2 through the water delivery pipe 12 for storage, so as to facilitate subsequent dust suppression, thereby realizing the comprehensive utilization of resources.

[0028] As an implementation manner of the present invention, refer to Figure 1 , Figure 2 , Figure 3 and Figure 6, further comprising a hollow column 4, a driving assembly 5, an adjusting assembly 6 and an atomizing assembly 7 disposed between two adjacent sections of the circulation pipe 3. The driving assembly 5 is disposed on the hollow column 4. The driving assembly 5 includes a straight pipe 51, a conical pipe 52 and a fan blade 53. The straight pipe 51 penetrates through the hollow column 4. The conical pipe 52 is disposed at the lower end of the straight pipe 51. The fan blade 53 is disposed at the upper end of the straight pipe 51. The two sections of the circulation pipe 3 on the hollow column 4 are coaxially arranged, and the axis of the circulation pipe 3 is offset from the axis of the hollow column 4. A plurality of driving blades 521 are circumferentially arrayed on the outer surface of the conical pipe 52, and driving grooves 522 are formed on the surface of the driving blades 521. The depth of the driving grooves 522 increases outward along the radial direction of the hollow column 4; the fan blade 53 includes a fixing block 531 and a plurality of V-shaped blades 532 circumferentially arrayed on the fixing block 531. The fixing block 531 is disposed on the straight pipe 51, and the opening direction of the V-shaped blade 532 is opposite to the rotation direction of the straight pipe 51.

[0029] Under the above settings, after the water flow enters the interior of the hollow column 4 through the circulation pipe 3, it will directly impact the driving grooves 522 formed on the driving blades 521. Thus, under the action of the impact force of the water flow, the driving blades 521 drive the conical pipe 52 to rotate. Since the conical pipe 52 is sequentially connected to the straight pipe 51 and the fan blade 53, the rotation of the conical pipe 52 drives the straight pipe 51 and the fan blade 53 to rotate. And during the rotation of the fan blade 53, the opening design of the V-shaped blade 532 can be used to reduce the wind resistance suffered during the rotation of the conical pipe 52 driven by the water flow impact. Furthermore, under the action of the adjusting assembly 6, the atomizing assembly 7 is driven to rotate around the axis of the hollow column 4, achieving the effect of expanding the water mist spraying range, and further improving the dust suppression effect to ensure the construction progress.

[0030] As an implementation manner of the present invention, referring to Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 and Figure 8 , the adjusting assembly 6 is connected to the driving assembly 5. The adjusting assembly 6 includes a fixing frame 61, a first guide pipe 62 and a second guide pipe 63 sleeved together, a hose 64, a block 65 with a hollow interior, a baffle 66, a corrugated pipe 67 and a gas guiding assembly 68. The fixing frame 61 is disposed on the straight pipe 51. One end of the first guide pipe 62 is hinged to the fixing frame 61. One end of the hose 64 is connected to the first guide pipe 62, and the other end penetrates into the interior of the straight pipe 51. The block 65 is sleeved on the first guide pipe 62. The baffle 66 is sleeved on the second guide pipe 63. The corrugated pipe 67 is disposed between the block 65 and the baffle 66 and is sleeved on the second guide pipe 63.

[0031] Under the above set conditions, during the rotation of the straight pipe 51, the fixed frame 61 is driven to rotate. During the rotation of the fixed frame 61, the first guide pipe 62 is driven to rotate. 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 following the first guide pipe 62. Since the conical pipe 52 is communicated with the straight pipe 51, and the straight pipe 51 is communicated with the first guide pipe 62 through the flexible pipe 64, the water flow will flow through the conical pipe 52, the straight pipe 51 and the flexible pipe 64 in sequence and then enter the interiors of the first guide pipe 62 and the second guide pipe 63, and finally be sprayed out in the form of water mist from the atomization assembly 7. After the water flow enters the interiors of the first guide pipe 62 and the second guide pipe 63, the connection between the corrugated pipe 67 and the stopper 65 and the baffle 66 can be used to achieve sealing, avoiding water leakage, so that all the water flow entering the interior of the first guide pipe 62 can be sprayed out from the atomization assembly 7.

[0032] As an implementation manner of the present invention, referring to Figure 1 , Figure 4 , Figure 5 , Figure 7 and Figure 8 , the atomization assembly 7 is connected to the adjustment assembly 6. The atomization assembly 7 includes two atomizing nozzles 71, and also includes an "I"-shaped pipe 72, a first piston 73 and an L-shaped rod 74. The "I"-shaped pipe 72 is arranged at the end of the second guide pipe 63. The two atomizing nozzles 71 are respectively arranged at the ends of the "I"-shaped pipe 72. The first piston 73 is arranged inside the "I"-shaped pipe 72. The two ends of the L-shaped rod 74 are respectively connected to the stopper 65 and the first piston 73.

[0033] Under the above set conditions, when the wind force is not enough to drive the V-shaped blade 532 to drive the straight pipe 51 to rotate at an accelerated speed (that is, a single atomizing nozzle 71 can normally handle the dust), the first piston 73 always blocks directly above the vertical section of the "I"-shaped pipe 72, thereby restricting the water flow rate ejected per unit time. While ensuring the dust treatment effect, it avoids wasting water resources, and at the same time can avoid the situation that the water flow rate flowing out per unit time is too large and reduces the dryness of the foundation pit, effectively ensuring the construction progress.

[0034] As an implementation manner of the present invention, referring to Figure 4 , Figure 5 , Figure 7 and Figure 8 , the air guide assembly 68 is arranged on the baffle 66. The air guide assembly 68 includes a second piston 681, an L-shaped pipe 682, a first one-way valve 683 and a second one-way valve 684. The second piston 681 is arranged inside the stopper 65 and is sleeved with the first guide pipe 62. The L-shaped pipe 682 penetrates through the stopper 65 and the baffle 66 and is sleeved with the second piston 681 and the second guide pipe 63 at both ends respectively. The first one-way valve 683 is arranged on the L-shaped pipe 682. The second one-way valve 684 is arranged on the stopper 65.

[0035] Under the above set conditions, when the wind force increases and drives the V-shaped blade 532 to drive the straight pipe 51 to rotate at an accelerated speed (that is, when the dust-raising level increases to the point where the water flow rate sprayed by a single atomizing nozzle 71 is insufficient to ensure the dust-removing 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 stopper 65 and the first piston 73, and the stopper 65 is fixedly arranged on the first diversion pipe 62, relative movement will occur between the "I"-shaped pipe 72 and the first piston 73 during the process of the "I"-shaped pipe 72 moving away from the hollow column 4, causing the first piston 73 to be misaligned with the upper port of the vertical section of the "I"-shaped pipe 72, so that water can enter the interior of the upper atomizing nozzle 71 and finally be sprayed out from the atomizing nozzle 71, achieving the effect of increasing the water flow rate sprayed per unit time. Moreover, the faster the rotation speed of the straight pipe 51 driven by the wind force, the smaller the blocking range of the first piston 73 on the upper port of the vertical section of the "I"-shaped pipe 72, until the first diversion pipe 62 and the second diversion pipe 63 are in a horizontal state, that is, the greater the dust-raising, the more water flow rate is sprayed per unit time, so as to ensure the construction progress on the basis of ensuring the dust-removing effect.

[0036] As an implementation manner of the present invention, referring to Figure 4 , Figure 5 , Figure 7 and Figure 8 , a spring 69 is arranged between the stopper 65 and the baffle 66, and the spring 69 is sleeved with the corrugated pipe 67. When the wind force does not reach the set value (this 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 rotation), the length of the spring 69 remains constant, that is, only when water drives the conical pipe 52 to drive the straight pipe 51 to rotate during the flow in the circulation pipe 3, the length of the spring 69 will not change. When the spring 69 is not deformed, the first piston 73 is located at the middle position of the upper end of the "I"-shaped pipe 72, and the length of the first piston 73 is greater than the diameter of the "I"-shaped pipe 72.

[0037] Under the above set conditions, on the one hand, when the wind force increases to drive the straight pipe 51 to rotate at an accelerated speed, under the action of centrifugal force, the second guide pipe 63 will move away from the first guide pipe 62, so that under the action of the stopper 65 and the baffle 66, the spring 69 is stretched. When the wind force decreases to a level insufficient to drive the straight pipe 51 to rotate at an accelerated speed, the spring 69 overcomes the action of centrifugal force and resets, that is, it drives the second guide pipe 63 to approach the first guide pipe 62. And during the process of the second guide pipe 63 approaching the first guide pipe 62, it can drive the "I"-shaped pipe 72 to move synchronously, so that the first piston 73 resets to block the upper port of the vertical section of the "I"-shaped pipe 72, thereby reducing the water flow rate sprayed per unit time, saving water resources on the basis of ensuring the dust suppression effect, and avoiding 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 causes the second guide pipe 63 to move away from the first guide pipe 62, the baffle 66 will move 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 check valve II 684 can pump external air into the inside of the stopper 65 for storage. And when the wind force decreases and the spring 69 pulls the baffle 66 to approach the stopper 65, the air stored inside the stopper 65 will enter the inside of the L-shaped pipe 682 under the action of the check valve I 683, and is sprayed out from the corresponding atomizing nozzle 71 through the second guide pipe 63 and the "I"-shaped pipe 72. That is, on the premise that the wind force drives the V-shaped blade 532 to drive the straight pipe 51 to rotate at an accelerated speed, when the wind force changes dynamically, the second piston 681 reciprocates, and can continuously transport air into the inside of the second guide pipe 63, thereby improving the atomizing effect of the atomizing nozzle 71, further ensuring the dust suppression effect, and further ensuring the construction progress.

[0038] Working principle: Fix each hollow column 4 at the designated position, use a water pump and a water suction pipe 11 to pump the water in the foundation pit that has not been discharged by the pipeline into the filter barrel 1 for filtration treatment. The filtered water is transported to the inside of the water storage barrel 2 through the water supply pipe 12. When dust suppression is required, the water pump can be used for pumping to realize the circulation of water flow in the circulation pipe 3. Since pumping water by the water pump is a conventional technical means, it will not be elaborated too much here; When the water flow flows inside the circulation pipe 3 and enters the corresponding hollow column 4, the water flow will directly act on the driving groove 522 on the driving blade 521, so as to drive the conical pipe 52 to rotate under the action of the impact force of the water flow. Since the conical pipe 52 is connected to the straight pipe 51, the straight pipe 51 is driven to rotate during the rotation of the conical pipe 52. During the rotation of the straight pipe 51, the fixed frame 61 installed on the straight pipe 51 is driven to rotate. Since the first diversion pipe 62 is hinged to the fixed frame 61 and is internally connected to the straight pipe 51 through the hose 64, and the second diversion pipe 63 is sleeved on the first diversion pipe 62, and a corrugated pipe 67 for preventing water leakage is sleeved on the outer walls of the first diversion pipe 62 and the second diversion pipe 63 together, part of the water entering the hollow column 4 can enter the inside of the second diversion pipe 63 through the conical pipe 52, the straight pipe 51, the hose 64 and the first diversion pipe 62. Since a stop block 65 is arranged on the first diversion pipe 62, a baffle 66 is arranged on the second diversion pipe 63, and a spring 69 is arranged between the stop block 65 and the baffle 66, the second diversion pipe 63 will follow the straight pipe 51 to rotate and drive the "I"-shaped pipe 72 and the two atomizing nozzles 71 installed thereon to rotate. And during the rotation, the water inside the second diversion pipe 63 can pass through the "I"-shaped pipe 72 and be sprayed out from the lower atomizing nozzle 71, so as to automatically expand the spraying range of the water mist under the action of the impact force of the water flow; Since a fixed block 531 and a V-shaped blade 532 are arranged at the upper end of the straight pipe 51, when the wind force is not enough to drive the V-shaped blade 532 to drive the straight pipe 51 to rotate at an accelerated speed, refer to Figure 2 , Figure 4 and Figure 5 , when the straight pipe 51 rotates under the action of the impact force of the water flow, the centrifugal force generated is not enough to overcome the elastic force of the spring 69, so the distance between the stop block 65 and the baffle 66 will not change, that is, the "I"-shaped pipe 72 and the piston I 73 inside it remain in a relatively static state, that is, the piston I 73 always blocks the upper port of the vertical section of the "I"-shaped pipe 72, preventing water from being sprayed out from the upper atomizing nozzle 71. Thus, when the wind force is small, it can not only ensure the dust reduction effect but also avoid wasting water resources, and can further avoid reducing the dryness of the foundation pit due to excessive dust reduction water consumption; When the wind force drives the V-shaped blade 532 to drive the straight pipe 51 to rotate at an accelerated speed, refer to Figure 6 , Figure 7 and Figure 8During the rotation of the straight pipe 51, the centrifugal force generated increases and can overcome the elastic force of the spring 69, causing the second diversion pipe 63 to move away from the stopper 65 under the action of the centrifugal force. Since the two ends of the L-shaped rod 74 are fixedly connected to the stopper 65 and the first piston 73 respectively, and the first piston 73 is movably arranged inside the "I"-shaped pipe 72, the L-shaped rod 74 can pull the first piston 73 during the process of the baffle 66 moving away from the stopper 65, causing a relative displacement between the first piston 73 and the "I"-shaped pipe 72, that is, the upper port of the vertical section of the first piston 73 and the "I"-shaped pipe 72 is misaligned. Therefore, water can be sprayed out from the two atomizing nozzles 71 simultaneously, thereby increasing the amount of water sprayed per unit time, and then improving the dust suppression effect when the wind force increases and the dust emission increases, and further ensuring the construction progress; Refer to Figure 5 and Figure 8 Since the second piston 681 is arranged inside the stopper 65, an L-shaped pipe 682 is arranged between the second piston 681 and the baffle 66, and the L-shaped pipe 682 is movably sleeved on the stopper 65. During the process of the baffle 66 moving away from the stopper 65, the second piston 681 can be driven to move inside the stopper 65 through the L-shaped pipe 682. Since a first one-way valve 683 is arranged on the L-shaped pipe 682 and a second one-way valve 684 is arranged on the stopper 65, external air will be pumped into the inside of the stopper 65 for storage through the second one-way valve 684 during the movement of the second piston 681. When the wind force decreases, the spring 69 contracts and drives the baffle 66 to approach the stopper 65, and the air stored inside the stopper 65 will enter the inside of the second diversion pipe 63 through the L-shaped pipe 682 and the first one-way valve 683. Since the wind force is continuously changing, the second piston 681 will move irregularly back and forth inside the stopper 65. Therefore, external air can be continuously transported into the inside of the second diversion pipe 63, and the air is sprayed out from the corresponding atomizing nozzles 71 after passing through the "I"-shaped pipe 72, thereby improving the atomization effect of the atomizing nozzles 71, and then ensuring the dust suppression effect, and further ensuring the construction progress.
