Description

Technical Field

[0001] This utility model relates to the technical field of dust suppression devices, specifically to a dust suppression device for building construction. Background Technology

[0002] Construction refers to the production activities during the implementation phase of a project. It is the process of building various types of buildings, or the process of turning the lines on the design drawings into physical objects at a designated location. On construction sites, it is difficult to avoid flying dust. When the dust concentration is high, it will affect the construction workers' operations. Generally, dust suppression devices are set up on the construction site to reduce the dust concentration.

[0003] Existing dust suppression devices generally use water atomization spraying to suppress dust at construction sites. Because the angle and direction of the atomizing nozzles are fixed, the spray range of the water mist is often fixed and cannot be adapted to the construction area. This often results in unnecessary waste of water when the construction area is small. Utility Model Content

[0030] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0031] See also Figure 1 , Figure 2 , Figure 3 Figure 4 As shown, according to an embodiment of the present utility model, a construction dust suppression device is provided, including: a support cylinder 1, in which a piston rod 2 is slidably installed, a connecting cylinder 3 is rotatably sleeved at the top of the piston rod 2, and the axial position of the piston rod 2 is hollow and communicates with the interior of the support cylinder 1 and the interior of the connecting cylinder 3, and an impeller 4 is provided in the bottom opening of the connecting cylinder 3.

[0032] Several atomizing nozzles 9 are equidistantly arranged on the outer periphery of the connecting cylinder 3 and are rotatably connected to the connecting cylinder 3 via connecting rods. The liquid inlet end of the connecting cylinder 3 is connected to the interior of the connecting cylinder 3 via a connecting piece 5.

[0033] The adjustment mechanism 7, located at the top of the connecting cylinder 3, is used to adjust the angle of the atomizing nozzle 9;

[0034] The limiting mechanism 8 is located on the outer periphery of the support cylinder 1 and is used to constrain and limit the piston rod 2 and the support cylinder 1.

[0035] The liquid injection component 6 is located below the limiting mechanism 8 and is used to inject water into the support cylinder 1.

[0036] In this embodiment, when using the improved construction dust suppression device, (first please refer to...) Figure 1 and Figure 4As shown, the bottom end of the support cylinder 1 extends outward to form a support leg, and the support leg has a threaded hole for fixing the support cylinder 1 to the ground with expansion bolts. Please refer to [reference needed]. Figure 2 and Figure 4 As shown, when the device is in use, the liquid injection component 6 is activated, continuously injecting water into the support cylinder 1. Please refer to... Figure 2 , Figure 3 and Figure 4 As shown, due to the constraint and limitation of the piston rod 2 by the limiting mechanism 8, the water injected into the support cylinder 1 flows upward through the inner hole of the piston rod and into the connecting cylinder 3. (The connecting cylinder 3 is equipped with a sealing ring to seal the gap between the piston rod 2 and the inner wall of the bottom opening of the connecting cylinder 3). The water entering the connecting cylinder 3 first fills the inner cavity of the connecting cylinder 3 due to the obstruction of the connecting piece 5, and then flows into the atomizing nozzle 9 through the connecting piece 5. Water mist is sprayed out from several atomizing nozzles 9. The water flowing in the connecting cylinder 3 blows onto the impeller 4, so that the impeller 4 applies an axial pushing force to the connecting cylinder 3, so that the connecting cylinder 3 drives the atomizing nozzle 9 to make a circular motion around the support cylinder 1.

[0037] Based on the above, the rotating atomizing nozzle 9 can continuously adjust the atomization angle to increase the spraying area of ​​the atomizing nozzle 9, and the centrifugal force of the water mist sprayed by the atomizing nozzle 9 can increase the diameter of the sprayed water mist.

[0038] Adjusting the water pressure inside the support cylinder 1 as needed can drive the adjustment mechanism 7 to start, adjusting the tilt angle of the atomizing nozzle 9 to further increase the diameter of the sprayed water mist, so that the sprayed water mist covers a wider area.

[0039] As needed, the water pressure injected into the support mechanism can be further increased, which can gradually release the constraint of the limiting mechanism 8 between the piston rod 2 and the support cylinder 1, so that the piston rod 2 can gradually slide out of the support cylinder 1, thereby further adjusting the overall length between the support cylinder 1 and the piston rod 2, and further increasing the diameter of the sprayed water mist, thereby further increasing the spraying area of ​​the water mist.

[0040] In a further preferred embodiment of this utility model, such as Figure 1 and Figure 3 As shown, the impeller 4 is located at the top of the opening at the top of the piston rod 2, and is fixedly connected to the inner wall of the connecting cylinder 3 by several support rods. The top of the connecting cylinder 3 is flared.

[0041] In this embodiment, please refer to Figure 1 and Figure 3 As shown, the impeller 4 and the connecting cylinder 3 are fixed by the support rod, which hardly affects the flow of water around the impeller 4.

[0042] In a further preferred embodiment of this utility model, such as Figure 2and Figure 3 As shown, the connector 5 includes several pressure relief valves 51, which are fixedly installed in a circular array on the outer peripheral wall of the top of the connector 3, and the liquid inlet end of the connector 3 is connected to the discharge end of the corresponding pressure relief valve 51 through a soft tube 52.

[0043] In this embodiment, please refer to Figure 2 and Figure 3 As shown, the water injected into the connecting cylinder 3 will first fill the inner cavity of the connecting cylinder 3 due to the obstruction of the pressure relief valve 51, so that a pressure difference is generated at both ends of the pressure relief valve 51. At this time, the water filling the inner cavity of the connecting cylinder 3 will be divided into several small water streams and simultaneously pass through the pressure relief valve 51 into the flexible tube 52 and be introduced into the atomizing nozzle 9 through the connecting tube. Subsequently, the water is atomized into water mist and sprayed out. The connection between the pressure relief valve 51 and the atomizing nozzle 9 through the flexible tube 52 will not affect the rotation of the atomizing nozzle 9.

[0044] In a further preferred embodiment of this utility model, such as Figure 1 and Figure 4 As shown, the liquid injection component 6 includes a water pump 61, which is fixedly installed on the outer peripheral wall of the bottom of the support cylinder 1. The discharge end of the water pump 61 is connected to a water injection pipe 62, and the end of the water injection pipe 62 away from the water pump 61 is inserted into the support cylinder 1 and fixedly connected to the support cylinder 1.

[0045] In this embodiment, please refer to Figure 1 and Figure 4 As shown, when the device is in use, the water pump 61 is started (the water pump 61 is a variable frequency controlled bidirectional pump, and the inlet end of the water pump 61 is connected to the external water source through a pipe). The started water pump 61 continuously draws water from the water source and injects the water into the water injection pipe 62, and then discharges it vertically upward into the support cylinder 1. The device can be intelligently controlled by an external computer or control host. The device has a high degree of intelligence and is convenient to use.

[0046] In a further preferred embodiment of this utility model, such as Figure 1 and Figure 3 As shown, the adjustment mechanism 7 includes several piston cylinders 71, which are fixedly mounted on the top of the connecting cylinder 3 in a circular array. The top opening of each piston cylinder 71 is connected to the inside of the support cylinder 1 through a conduit. A piston rod 72 is slidably mounted inside the piston cylinder 71, and the bottom end of the piston rod 72 slides through the tube wall of the connecting cylinder 3 and is rotatably connected to the tail end of the atomizing nozzle 9.

[0047] In this embodiment, please refer to Figure 1 and Figure 3As shown, after the inner cavity of the connecting pipe is filled with water, some water flows through the conduit, such as piston cylinder 71, thereby applying a downward thrust to piston rod 72 by the water pressure injected into the support cylinder 1, so as to adjust the length of piston rod 72 outside piston cylinder 71 according to the injected water pressure, thereby pushing the height of the tail end of the atomizing nozzle 9 downward by piston rod 72, so as to adjust the tilt angle of the atomizing nozzle 9.

[0048] In a further preferred embodiment of this utility model, such as Figure 3 As shown, a spring 73 is wound around the outer periphery of piston rod 2 72, and the two ends of spring 73 are fixedly connected to the plug plate of piston rod 2 72 and the inner wall of piston cylinder 1 71, respectively.

[0049] In this embodiment, please refer to Figure 3 As shown, the spring 73 continuously applies an upward thrust to the piston rod 72. When the thrust of the water on the piston rod 72 is greater than the thrust of the spring 73 on the piston rod 72, the piston rod moves downward, compressing the spring 73, until the thrust of the spring 73 on the piston rod 72 is equal to the thrust of the water on the piston rod 72. Thus, by increasing the water pressure, piston rods 72 of different lengths are gradually pushed out of the piston cylinder 71. When the water pressure decreases, due to the push of the spring 73 on the piston rod 72, the corresponding length of piston rod 72 automatically retracts into the piston cylinder 71. The device has a high degree of automation and does not require an additional drive structure, reducing the production cost of the device. In addition, the increase in water pressure can also simultaneously increase the spray volume of the atomizing nozzle 9.

[0050] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the limiting mechanism 8 includes several piston cylinders 81, which are divided into two groups and fixedly installed on the outer periphery of the support cylinder 1. The distance between two adjacent piston cylinders 81 is equal. A piston rod 82 is slidably installed inside the piston cylinder 81. The end of the piston rod 82 near the support cylinder 1 is inclined and inserted into the support cylinder 1. An electric control valve 83 is fixedly installed through the outer periphery of the support cylinder 1. The discharge end of the electric control valve 83 is connected to the interior of the bottom support cylinder 1 and the two adjacent support cylinders 1 through a connecting pipe.

[0051] In this embodiment, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, when water is injected into the support cylinder 1, due to the mutual contact between the bottom piston rod 382 and the piston rod 2 plug plate, the upward flow of water pushes the piston rod 2, which will not push the piston rod 2 out of the support cylinder 1.

[0052] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, piston cylinder 2 81 is filled with air, and the amount of gas in the upper piston cylinder 2 81 is greater than the amount of gas in the lower piston cylinder 2 81.

[0053] In this embodiment, the air filling the piston cylinder 2 81 creates a high-pressure chamber inside the piston cylinder 2 81, thereby applying a thrust toward the support cylinder 1 to the piston rod 3 82. The thrust on the piston rod 3 82 varies depending on the amount of air filling the piston cylinder 2 81, and gradually increases from bottom to top.

[0054] Please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, when the water pressure injected into the support cylinder 1 is further increased, the electric control valve 83 opens simultaneously. At this time, some water in the support cylinder 1 flows into the piston cylinder through the electric control valve 83 and the connecting pipe, thereby applying a corresponding thrust to the piston rod to push the piston rod 82 into the piston cylinder 2. As the water pressure increases, the piston rod 82 can be retracted into the piston cylinder 2 81 from bottom to top, so that the piston rod 2 gradually extends out of the support cylinder 1. Thus, the overall height of the piston rod 2 and the support cylinder 1 can be adjusted as needed, and the height of the atomizing nozzle 9 can be gradually adjusted. This can be adjusted in stages to avoid most of the piston rod 2 extending out of the support cylinder 1, which would affect the use of the device.

[0055] After the device is used, the water pump 61 pumps out the water from the support cylinder 1. As the water in the support cylinder 1 decreases,

[0056] A downward suction force can be applied to piston rod 2. Combined with the weight of piston rod 2 itself, piston rod 2 can be gradually retracted into support cylinder 1 until the stop plate of piston rod 2 contacts the inner wall of support cylinder 1. When the stop plate of piston rod 2 moves to the position of piston rod 3 82, the piston rod 3 82 is squeezed out of support cylinder 1 by the contact between the stop plate of piston rod 2 and the inclined surface of piston rod 3 82. The contact between the stop plate of piston rod 2 and piston rod 3 82 is automatically released, so that piston rod 3 82 will not affect the downward movement of piston rod 2. When the stop plate of piston rod 2 moves away from the position of piston rod 3 82, the piston rod 3 82 is automatically reset and inserted into support cylinder 1 due to the pushing of the gas in piston cylinder 2 81. The device has a high degree of automation.

[0057] Working principle: When this improved construction dust suppression device is in use, water is continuously injected into the support cylinder 1 by water pump 61, and then the water is atomized and sprayed out through the atomizing nozzle 9 to form a circular spray range. According to the size of the construction area, the water pressure of water pump 61 is adjusted, thereby adjusting the height and angle of the atomizing nozzle 9 to form a desired spray range that covers the entire construction area. Finally, the dust absorbs the water mist, increasing the weight of the dust, causing the dust to fall automatically to the ground, thereby reducing the dust content in the air at the construction site.

[0058] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.

[0059] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. The above are only preferred embodiments of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
