Description

Technical Field

[0001] The utility model relates to the technical field of dust prevention in road construction, in particular to a sectioned dust reduction device for a construction channel. Background Art

[0002] With the development of the times, people's awareness of environmental protection has been enhanced, and higher environmental protection requirements have been put forward in the construction field. High-dust operations such as earth excavation and transportation, foundation construction, etc. are unavoidable in construction. Dust reduction is particularly important in road construction.

[0003] There are two main dust reduction measures in current construction sites. First, through dust reduction equipment such as fog cannons, but the construction site is complex and changeable, the use of dust reduction equipment is often subject to many restrictions, and the investment in dust reduction equipment and the maintenance of equipment during use will greatly increase the economic cost, which is not very applicable and economical for most construction sites; second, laying out spray pipes on both sides of the construction road, usually arranged around the top of the fence, this type of dust reduction measure greatly reduces the investment in dust reduction equipment.

[0004] In the implementation of the aforementioned dust reduction measures of installing sprinkler pipes on both sides of the construction road, the prior art generally sets a long-distance sprinkler pipe on the top of the enclosure along the extension direction of the enclosure to uniformly supply water, and sets a plurality of sprinkler ports at intervals on the sprinkler pipe to provide a dust reduction effect. This implementation method has the problem that due to the unified water supply of the long-distance sprinkler pipe, when the required spraying area is small, the waste of water resources for long-distance spraying is relatively serious. When the construction site is complex and the top of the enclosure is not located in the same straight line, the long-distance sprinkler pipe is difficult to apply. Chinese Patent: CN205314048U discloses a dust reduction device comprising a plurality of side sprinkler heads, each of which corresponds to a vertical pipe. Although such an implementation is more adaptable than the aforementioned long-distance sprinkler pipe set on the top, it is more difficult to fix the vertical pipeline, so the dust removal device is more complicated to lay out. Utility Model Content

[0005] In order to overcome the problems of poor adaptability of long-distance sprinkler pipes in existing sprinkler pipe dust reduction and inconvenient installation and layout when a single side sprinkler head corresponds to a single vertical pipe, the utility model provides a construction channel segmented dust reduction device which takes into account both adaptability and installation convenience.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] The sectioned dust suppression device for the construction channel comprises an enclosure, a water pump and a water pipe. The water pipe is detachably connected to the enclosure. The water pump is used to transport water to the water pipe. The water pipe comprises a main pipe and a branch pipe. The main pipe is arranged at the lower end or below the enclosure. The extension direction of the main pipe is consistent with the extension direction of the enclosure. The branch pipe comprises a vertical pipe. One end of the vertical pipe is connected to the main pipe. A spray port is provided on the branch pipe. A plurality of branch pipes arranged at intervals are connected to the main pipe. The branch pipe also comprises a transverse pipe. The transverse pipe is connected to the end of the vertical pipe in the extension direction away from the main pipe. The transverse pipe is parallel to the main pipe. The length of the transverse pipe is 9m-12m. A plurality of spray ports are provided on the transverse pipe.

[0008] In the present application, a construction channel segmented dust reduction device is provided, in which a main pipeline is arranged at the lower end or below the enclosure, and a plurality of branch pipelines arranged at intervals are connected to the main pipeline, and the branch pipeline includes a vertical pipeline and a transverse pipeline. The transverse pipeline is arranged at the upper end or above the enclosure, and a spray port for spraying dust reduction is provided, and the vertical pipeline is used to connect the transverse pipeline in the main pipeline with the main pipeline. In practice, the commonly used horizontal length of the enclosure is 2.5-3.5m, and the preferred transverse pipeline length here is 9-12m. Every 3-5 enclosures can correspond to a transverse pipeline, that is, a branch pipeline. Due to the provision of multiple branch pipelines, it has stronger adaptability than the existing long-distance spray pipes; compared with each spray port corresponding to a vertical pipeline, the installation convenience of the present application is higher.

[0009] In some embodiments, at least one branch pipeline is provided with a valve to control the connection or disconnection between the branch pipeline and the main pipeline.

[0010] In this embodiment, a valve is set on the branch pipeline to control the connection or disconnection of the branch pipeline with the main pipeline. Combined with the above, the transverse pipeline is set in sections in this application, and the section control in the road construction area can be realized to save water resources. The valve here includes electrical valves and mechanical valves.

[0011] In some embodiments, the valve is a solenoid valve, and a vehicle probe is additionally provided, and the vehicle probe is electrically connected to the solenoid valve.

[0012] In this embodiment, a vehicle probe is added to detect whether there are vehicles passing through the construction section, so as to determine whether spraying dust reduction is needed. The valve is preferably a solenoid valve. The vehicle probe and the solenoid valve are electrically connected. Combined with the aforementioned segmented control within the road construction area, the former is a spatial segmentation, and the latter is combined with vehicle probe detection to achieve temporal segmentation. The combination of the two further improves the effective utilization rate of water resources of the dust reduction device as a whole.

[0013] In some embodiments, each branch pipeline is provided with a corresponding vehicle probe and a solenoid valve.

[0014] In this embodiment, each branch pipeline is provided with a corresponding vehicle probe and a solenoid valve to achieve more precise control over different branch pipelines.

[0015] In some embodiments, 3-6 spray ports are opened on the transverse pipe corresponding to each branch pipe, and each spray port is connected to an atomizing nozzle.

[0016] In this embodiment, 3-6 spray ports are provided on each transverse pipe, and the spacing between the spray ports is preferably 1-3 m, so as to effectively reduce dust on the construction section.

[0017] In some embodiments, the water supply pipe is a PPR water supply pipe.

[0018] In this embodiment, the water supply pipe adopts PPR water supply pipe, which is a commonly used water and electricity pipe material on construction sites. This material is selected here and can be hot-melt connected at the construction site, which not only meets the function of on-site dust reduction, but also can be recycled, greatly reducing the cost of dust reduction investment on the construction site.

[0019] In some embodiments, the water pump is connected to the tertiary sedimentation tank, and the water in the tertiary sedimentation tank is transported to the water pipe through the water pump.

[0020] In some embodiments, on the branch pipeline, an end of the vertical pipeline extending away from the main pipeline is connected to the middle position of the horizontal pipeline in the length direction.

[0021] In this embodiment, on the branch pipeline, the vertical pipeline is connected to the middle position of the horizontal pipeline, so that the overall force is more uniform, which is convenient for installation and avoids deformation or displacement of the branch pipeline during operation.

[0022] The beneficial effects of the utility model are as follows: multiple branch pipes are set up, which have stronger adaptability than the existing long-distance sprinkler pipes, and are more convenient to install than the vertical pipes corresponding to each sprinkler port; further, valves are added to make it possible to divide the space into different areas for dust reduction to save water resources; further, probes are added as detection devices to segment the time to further improve the utilization rate of water resources; further, 3-6 sprinkler ports are opened in combination with the length of the horizontal pipe to effectively reduce dust; further, the water supply pipe adopts a PPR water supply pipe and the water source is a three-stage sedimentation tank to further reduce the investment cost of dust reduction; the vertical pipe is connected to the middle position of the horizontal pipe, so that the overall force is more uniform, which is convenient for installation and improves the service life of the device.

[0028] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0029] like Figure 1-Figure 3 As shown, the utility model provides a segmented dust reduction device for a construction channel.

[0030] The construction channel segmented dust reduction device comprises an enclosure 7, a water pump 1 and a water pipe. The water pipe is detachably connected to the enclosure 7. The water pump 1 is used to transport water to the water pipe. The water pipe comprises a main pipeline 3 and a branch pipeline 5. The main pipeline 3 is arranged at the lower end or below the enclosure 7. The extension direction of the main pipeline 3 is consistent with the extension direction of the enclosure 7. The branch pipeline 5 comprises a vertical pipeline 51. One end of the vertical pipeline 51 in the extension direction is connected to the main pipeline 3. A spray port 6 is provided on the branch pipeline 5. A plurality of branch pipelines 5 arranged at intervals are connected to the main pipeline 3. The branch pipeline 5 also comprises a transverse pipeline 52. The transverse pipeline 52 is connected to the end of the vertical pipeline 51 in the extension direction away from the main pipeline 3. The transverse pipeline 52 is parallel to the main pipeline 3. The length of the transverse pipeline 52 is 9m-12m. A plurality of spray ports 6 are provided on the transverse pipeline 52.

[0031] In the present application, a construction channel segmented dust reduction device is provided, wherein a main pipeline 3 is arranged at the lower end or below the enclosure 7, and a plurality of branch pipelines 5 arranged at intervals are connected to the main pipeline 3, and the branch pipeline 5 comprises a vertical pipeline 51 and a transverse pipeline 52, wherein the transverse pipeline 52 is arranged at the upper end or above the enclosure 7, and a spray port 6 for spraying dust reduction is provided, and the vertical pipeline 51 is used for connecting the transverse pipeline 52 in the main pipeline 3 with the main pipeline 3. In practice, the horizontal length of the enclosure 7 commonly used is 2.5-3.5m, and the preferred transverse pipeline 52 length here is 9-12m, and every 3-5 enclosures 7 can correspond to a transverse pipeline 52, that is, to a branch pipeline 5. Due to the arrangement of a plurality of branch pipelines 5, the adaptability is stronger than that of the existing long-distance spray pipes; and the installation convenience of the present application is higher than that each spray port 6 corresponds to a vertical pipeline 51.

[0032] In this embodiment, the main road pipeline 3 is pre-buried below the construction road surface 9, that is, below the aforementioned enclosure 7. In some embodiments, the main road pipeline 3 is arranged at the lower end of the enclosure 7.

[0033] Furthermore, at least one branch pipeline 5 is provided with a valve to control the connection or disconnection of the branch pipeline 5 with the main pipeline 3. In combination with the above, the transverse pipeline 52 in the present application is arranged in sections, and the section control of the area within the construction road pavement 9 can be achieved at this time to save water resources. The valve here includes electrical valves and mechanical valves.

[0034] Specifically, the valve in this embodiment is a solenoid valve 8, and a vehicle probe (not shown in the figure) is also provided, and the vehicle probe is electrically connected to the solenoid valve 8. In this embodiment, a vehicle probe is provided to detect whether a vehicle passes through the construction section, so as to determine whether spraying dust reduction is required. The valve is preferably a solenoid valve 8, and the vehicle probe is electrically connected to the solenoid valve 8. Combined with the aforementioned segmented control in the road construction area, the former is a spatial segmentation, and the latter is a temporal segmentation in combination with the vehicle probe detection. The combination of the two further improves the effective utilization rate of the water resources of the dust reduction device as a whole.

[0035] It is worth explaining that the vehicle probe is a sensor for sensing the vehicle, so as to control the connection or closing of the branch pipe 5 at a fixed point in this embodiment. Specifically, the vehicle probe is electrically connected to the solenoid valve 8. In this embodiment, the vehicle probe detection signal is collected to the dust fall sensor control box 2, and the solenoid valve 8 and the dust fall sensor control box 2 are connected through the control line 4.

[0036] In some embodiments, a vehicle probe and a solenoid valve 8 are provided for each branch pipeline 5 to achieve more accurate control of different branch pipelines 5. This is a preferred embodiment and is not specifically limited. In practice, optimization can be made according to specific circumstances. For example, only one vehicle probe can be provided for a continuous construction section to simplify the structure and line.

[0037] In this embodiment, 3-6 spray ports 6 are provided on the transverse pipe 52 corresponding to each branch pipe 5, and each spray port 6 is connected to an atomizing nozzle. In practice, the spray ports 6 are preferably spaced 1-3 m apart. Considering the length of the transverse pipe 52, 3-6 spray ports 6 are preferably provided on the transverse pipe 52.

[0038] In this embodiment, the water pipe uses a PPR water supply pipe. This material is a common water and electricity pipe material on the construction site. This material is selected here and can be hot-melt connected on the construction site, which not only meets the function of on-site dust reduction, but also can be recycled, greatly reducing the cost of dust reduction investment on the construction site. In this embodiment, the main pipeline 3 is DN32, and the branch pipeline 5 is DN25 or DN15, both of which are commonly used specifications and materials on site.

[0039] In this embodiment, the water pump 1 is connected to the tertiary sedimentation tank 10, and the water in the tertiary sedimentation tank 10 is transported to the water pipe through the water pump 1. The water pump 1 is a pressurized water pump with a power of about 30kw, which pressurizes water from the tertiary sedimentation tank 10 to various positions of the water pipe.

[0040] In this embodiment, on the branch pipeline 5, the end of the vertical pipeline 51 extending away from the main pipeline 3 is connected to the middle position of the length direction of the horizontal pipeline 52. This makes the overall force more uniform, facilitates installation, and avoids deformation or displacement of the branch pipeline 5 during operation.

[0041] It is worth explaining that in this embodiment, both sides of the construction road surface 9 are provided with spray ports 6, that is, both sides are provided with branch pipelines 5, and in this application, the main pipeline 3 is initially pre-buried to connect both sides of the construction road surface 9. Figure 1 In order to avoid the overlap of the main pipeline 3 and the branch pipeline 5, which affects the intuitiveness, Figure 1 The main pipeline 3 is highlighted above. Figure 1 The branch pipe 5 is highlighted below.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
