Description

Technical Field

[0001] This invention relates to the field of dust suppression technology in engineering construction, and in particular to a split-type dust suppression device. Background Technology

[0002] Air pollution, also known as atmospheric pollution, is defined by the International Organization for Standardization (ISO) as the phenomenon where certain substances enter the atmosphere due to human activities or natural processes, reach a sufficient concentration, and remain there for a sufficient period of time, thereby endangering human comfort, health, welfare, and the environment. Dust generated during construction is a very important part of urban air pollution. In order to reduce dust generated during construction, dust suppression devices are installed around construction sites.

[0003] In the prior art, patent CN 217680978 U discloses a green construction guardrail for reducing dust, including a main water pipe, a spraying device, and a partition. The main water pipe is used to connect to high-pressure water, the spraying device is installed around the main water pipe, and the spraying device is used to spray high-pressure water from the main water pipe cavity to reduce dust. The partition is installed around the main water pipe and is used to isolate the construction site. This guardrail can improve the situation where dust in the construction area easily passes through the guardrail and pollutes the surrounding environment. However, the protective effect consists only of the blocking effect of the guardrail and the local dust reduction of the spraying device, resulting in a poor dust reduction effect, and it can only meet the dust protection requirements at a specific height.

[0004] In view of this, it is necessary to design a split-type dust suppression device to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a split-type dust suppression device that can meet the dust suppression needs at different heights on construction sites and effectively improve the dust suppression effect.

[0006] To achieve the above-mentioned objective, the present invention provides a split-type dust suppression device, comprising:

[0007] The protective structure includes a first support frame and a second support frame connected to the first support frame and movable up and down relative to the first support frame, with protective netting provided on both support frames.

[0008] A height adjustment structure is used to adjust the height of the second support frame relative to the first support frame;

[0009] The spray assembly includes a spray pipe mounted on the top of the second support frame via a stand, and the spray pipe is provided with a plurality of nozzles;

[0010] The water-blocking structure is configured in accordance with the spray assembly, so that part of the water sprayed from the spray pipe is sprayed onto the water-blocking structure and flows down along the water-blocking structure, forming a water curtain on the side of the protective net facing the construction site. At the same time, during the process of water spraying onto the water-blocking structure, a local water mist area is also formed on the upper part of the protective structure.

[0011] As a further improvement of the present invention, the spray pipe is arranged parallel to the length direction of the second support frame and is arc-shaped, and a plurality of nozzles are arranged at intervals along the axial direction of the spray pipe on the spray pipe.

[0012] As a further improvement of the present invention, the spray pipe is rotatably connected to the support frame, and a drive component for driving the spray pipe to rotate in order to adjust the orientation of all the nozzles is also connected to the spray pipe.

[0013] As a further improvement of the present invention, the water-blocking structure is a water-blocking cover, and the water-blocking cover is fixed on the upright.

[0014] As a further improvement of the present invention, the nozzles are arranged in two rows at radial intervals along the spray pipe, wherein the upper row of nozzles is arranged facing the lower part of the water baffle, and the lower row of nozzles is arranged facing the lower part of the water baffle.

[0015] As a further improvement of the present invention, the height adjustment component includes a height adjustment part disposed on one side of the second support frame and a sliding connection part disposed on the other side of the second support frame. The height adjustment part includes a vertical threaded rod disposed on the first support frame, a slider disposed on the vertical threaded rod, and a drive component for driving the vertical threaded rod to rotate; the second support frame is connected to the slider.

[0016] As a further improvement of the present invention, the sliding connection includes a vertical guide rod disposed on the side of the first support frame away from the height adjustment part and a guide block sleeved on the vertical guide rod; the second support frame is connected to the guide block.

[0017] As a further improvement of the present invention, limit plates are also provided at the upper and lower ends of the vertical guide rod.

[0018] As a further improvement of the present invention, a first connecting portion and a second connecting portion that engages with the first connecting portion are respectively provided on both sides of the first support frame.

[0019] As a further improvement of the present invention, both ends of the bottom of the first support frame are provided with height-adjustable bottom support structures.

[0020] The beneficial effects of this invention are:

[0021] 1. This invention, by installing a spray assembly at the top of the protective net and a water-blocking cover above the spray assembly, allows water sprayed from the spray assembly to flow down the water-blocking cover during dust suppression, forming a water curtain on the side of the protective net facing the construction site. This water curtain blocks dust, creating a double barrier in conjunction with the protective net's dust-blocking effect. This effectively reduces dust pollution of the surrounding environment by penetrating the protective fence. The water curtain also adsorbs dust. Furthermore, due to the high flow rate of the water sprayed from the spray assembly, when the water hits the water-blocking cover, it forms a localized water mist upon impact. This water mist adheres to the protective net, further enhancing the dust-proof effect of the protective net by adsorbing dust.

[0022] 2. The present invention, through the setting of spray components and water-blocking covers, enables water mist to adhere to the protective net. The water mist adsorbs dust, improving the protective effect of the net against dust. At the same time, the water curtain formed can serve as the first protective layer, providing initial blocking of dust. Combined with the secondary barrier of the protective net, it can effectively reduce the occurrence of dust passing through the protective net and polluting the surrounding environment.

[0023] 3. The water sprayed directly onto the dusty area by the spraying component of the present invention can reduce dust by adsorbing dust. Combined with the adsorption of dust by water curtain and water mist, and the blocking of dust by protective net and water curtain, it can effectively reduce dust generated on the construction site and reduce dust pollution to the environment.

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0036] Additionally, it should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0037] like Figures 1-4 As shown, the present invention provides a split-type dust suppression device, comprising:

[0038] The protective structure includes a first support frame 10 and a second support frame 20 connected to the first support frame 10 and movable up and down relative to the first support frame 10. Both support frames are provided with protective nets 30.

[0039] A height adjustment structure is used to adjust the height of the second support frame 20 relative to the first support frame 10;

[0040] The spray assembly includes a spray pipe 42 mounted on the top of the second support frame 20 via a stand 41, and the spray pipe 42 is provided with a plurality of nozzles 43;

[0041] The water-blocking structure is configured in accordance with the spray assembly, so that part of the water sprayed from the spray pipe 42 is sprayed onto the water-blocking structure and flows down along the water-blocking structure, forming a water curtain on the side of the protective net 30 facing the construction site. At the same time, during the process of water spraying onto the water-blocking structure, a local water mist area is also formed on the upper part of the protective structure.

[0042] Specifically, the spray pipe 42 is arranged parallel to the length direction of the second support frame 20 and is arc-shaped. Several nozzles 43 are arranged axially on the spray pipe 42. In this embodiment, the spray pipe 42 is connected to the upright frame 41 by a bearing, and a driving component (not shown in the figure) for driving the spray pipe 42 to rotate is also connected to the spray pipe 42. Under the action of the driving component, the spray pipe 42 can rotate relative to the upright frame 41 to adjust the orientation of the nozzles 43 as needed. When it is necessary to clean the protective net 30, the spray pipe 42 is rotated, and the high-pressure water sprayed from the spray pipe 42 is used to rinse the protective net 30 to ensure the air permeability of the protective net 30.

[0043] Specifically, the water-blocking structure is a water-blocking cover 50, which is fixed on the upright frame 41. In this embodiment, the water-blocking cover 50 is installed on the top of the upright frame 41 and is a horizontal triangular prism structure. In the horizontal state, the bottom of the triangular prism structure is open. Compared with setting a water-blocking plate, the water-blocking cover 50 can concentrate water. By changing the direction of water flow using the side wall of the water-blocking cover 50, a water curtain is formed on the side of the protective net 30 near the construction site. At the same time, when the water with a certain flow rate hits the side wall of the protective cover, a local water mist area is formed, so that a certain amount of water mist adheres to the upper part of the protective net 30. The water mist adsorbs dust, enhancing the dust blocking effect of the protective net 30.

[0044] Specifically, two rows of nozzles 43 are arranged radially along the spray pipe 42. The upper row of nozzles 43 faces the lower part of the water baffle 50, and the lower row of nozzles 43 faces the lower part of the water baffle 50. This allows the upper row of nozzles 43 to work with the water baffle 50 to form a water mist that adheres to the protective net 30. At the same time, a water curtain is formed on the side of the protective net 30 closest to the construction site to block and absorb dust. The water jet from the lower row of nozzles 43 passes over the water baffle 50 and sprays towards the construction site for dust suppression.

[0045] Specifically, such as Figure 5 The nozzle 43 has a truncated cone 431 with a diameter that gradually increases along the water flow direction embedded at its outlet. This creates a circumferential gap between the sidewall of the truncated cone 431 and the nozzle 43 outlet. When water flows to the nozzle 43 outlet, it is sprayed outwards along the gap, forming an umbrella-shaped water mist. The diffusion of this water mist enhances the dust suppression effect of the spray. Simultaneously, the presence of the truncated cone 431 also provides a certain pressure boosting effect at the nozzle 43 outlet, increasing the water jet range. In this embodiment, the truncated cone 431 is threadedly connected to the connecting rod 432 located at the nozzle 43 outlet.

[0046] Specifically, the height adjustment assembly includes a height adjustment part disposed on the right side of the second support frame 20 and a sliding connection part disposed on the corresponding left side of the second support frame 20. The height adjustment part includes a vertical threaded rod 61 disposed on the first support frame 10, a slider 62 disposed on the vertical threaded rod 61, and a drive assembly for driving the vertical threaded rod 61 to rotate. The slider 62 is connected to the right side of the second support frame 20. Figure 6 and Figure 7 As shown, the driving assembly includes an adjustment box 631 fixed on the first support frame 10. The adjustment box 631 has an internal accommodating space. The lower end of the vertical threaded rod 61 passes through the adjustment box 631 and is connected to a first gear 632. The first gear 632 is coaxially arranged with the vertical threaded rod 61, and the vertical threaded rod 61 is connected to the top of the adjustment box 631 through a bearing. A horizontal rotating rod 634 is also arranged below the vertical threaded rod 61 in the accommodating space. One end of the rotating rod 634 is connected to the side wall of the adjustment box 631 through a bearing, and the other end passes through the outside of the adjustment box 631 and is connected to a driving component. A second gear 633 is sleeved on the part of the rotating rod 634 inside the adjustment box 631. The second gear 633 is perpendicularly meshed with the first gear 632. The driving component drives the second gear 633 to rotate, which in turn drives the first gear 632 to rotate, thereby causing the vertical threaded rod 61, which is fixedly connected to the first gear 632, to rotate and drive the slider 62 to move up and down.

[0047] Specifically, such as Figure 6 As shown, the driving component is a rotating handle 636; the portion of the rotating rod 634 located outside the regulating box 631 is fitted with a third gear 635; a rotation limiting structure is also provided on the outer wall of the regulating box 631, the rotation limiting structure including a bracket 641 fixed on the outer wall of the regulating box 631, two parallel horizontal guide rails 642 are provided on the bracket 641, toothed blocks 644 pass through the horizontal guide rails 642, and a spring 643 is also provided between the two horizontal guide rails 642, one end of the spring 643 being connected to the horizontal guide rail 642. One end is connected to the other end, which is connected to the toothed block 644. When the spring 643 is in its normal extension and retraction state, the toothed block 644 abuts against the third gear 635 to limit the third gear 635 and prevent the third gear 635 from rotating under external interference. When the gear moves to the left along the horizontal guide rail 642 under the action of force until the spring 643 is in the contracted state, the toothed block 644 is disconnected from the third gear 635. Rotating the handle 636 can make the third gear 635 rotate to adjust the height of the second support frame 20.

[0048] Specifically, such as Figure 1 and Figure 8As shown, the sliding connection includes a vertical guide rod 71 disposed on the left side of the first support frame 10 and a guide block 72 sleeved on the vertical guide rod 71; the left side of the second support frame 20 is connected to the guide block 72. The vertical guide rod 71 and the guide block 72 ensure that when the height of the second support frame 20 is adjusted using the height adjustment component, the left side of the second support frame 20 can move stably upwards. Furthermore, the combination of the height adjustment component and the sliding connection ensures that the second support frame 20 remains stable during height adjustment. Additionally, limiting plates 73 are provided at both ends of the vertical guide rod 71 to limit the movement distance of the second support frame 20.

[0049] Specifically, the first support frame 10 has a first connecting part and a second connecting part that engages with the first connecting part on both sides, so as to quickly install adjacent dust suppression devices by utilizing the cooperation of the first connecting part and the second connecting part to form a dust suppression protection zone. In this embodiment, the first connecting part is a pin 11, and the second connecting part is a connecting plate 12 with a pin hole in the middle, so that the installation of adjacent dust suppression devices can be completed by inserting the pin 11 into the corresponding pin hole.

[0050] Specifically, both ends of the bottom of the first support frame 10 are provided with height-adjustable bottom support structures. In this embodiment, the bottom support structure includes an adjusting rod 81 connected to the bottom of the first support frame 10 and a support cylinder 82 with an open top. The adjusting rod 81 passes through the top opening of the support cylinder 82 and can move up and down relative to the support cylinder 82. The adjusting rod 81 has several adjusting holes 811 spaced vertically, and the upper part of the support cylinder 82 has a corresponding through hole. After adjusting the height of the adjusting rod 81 relative to the support cylinder 82 as needed, a bolt 83 is inserted into the adjusting hole 811 through the through hole to keep the adjusting rod 81 fixed relative to the support cylinder 82. The support cylinder 82 is also provided with several inclined support plates 84 to improve the support stability of the support cylinder 82.

[0051] Specifically, the present invention, through the setting of a bottom support structure and a height adjustment component, can meet the requirements of construction sites for protective areas of different heights.

[0052] The working principle of the split-type dust suppression device provided by the present invention will be explained below.

[0053] In use, first, according to the size of the construction area, set up the corresponding number of split dust suppression devices around the outside of the construction area. Quickly connect adjacent dust suppression devices by engaging the first and second connecting parts. At the same time, adjust the height of the adjusting rod 81 relative to the support cylinder 82 to adapt to uneven construction sites or to form dust-proof areas of different heights as needed. When adjusting the bottom support structure to the maximum height still cannot meet the height requirements of the construction site for the dust-proof area, adjust the height adjustment component to move the second support frame 20 upward relative to the first support frame 10. After the height adjustment is completed, turn on the spray component so that the water from the upper row of nozzles 43 sprays towards the water barrier 50, forming a water curtain on the side of the protective net 30 facing the construction site. At the same time, a local water mist area is also formed on the upper part of the protective net 30, so that the upper part of the protective net 30 is covered with water mist. The water mist is used to absorb dust and increase the protective effect of the protective net 30. The water from the lower row of nozzles 43 sprays over the water barrier 50 and sprays towards the dust area for dust suppression.

[0054] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
