Description

Technical Field

[0001] This utility model relates to the field of road construction, and in particular to a spray dust suppression device for road construction. Background Technology

[0002] Road construction generates large amounts of PM10 and PM2.5 dust particles. These particles remain suspended in the air, causing air quality deterioration in and around the construction area, exacerbating smog. In windy conditions, these particles can spread several kilometers away, polluting surrounding residential areas, farmland, or water sources, and affecting plant photosynthesis and ecological balance. Therefore, dust suppression systems are typically installed on top of construction barriers during road construction. These systems atomize water and spray it into the air, causing the water mist to combine with dust particles, increasing their weight and accelerating dust settling, thus achieving dust reduction.

[0003] In existing technologies, the nozzles in dust suppression spraying devices are generally fixed structures with a relatively fixed spraying direction. In windy environments, the nozzles cannot dynamically change the spraying direction according to the wind direction. When the wind direction changes, dust will be blown to different areas, and a fixed spraying direction may result in the water mist not accurately covering the dust diffusion path, thus leading to poor spraying effect.

[0004] Therefore, this application provides a spray dust suppression device for road construction to meet the requirements. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a spray dust suppression device for road construction to solve the problem that in existing high-wind environments, the fixed spray direction may cause the water mist to fail to accurately cover the dust diffusion path.

[0006] To solve the problems mentioned above, this utility model is implemented through the following technical solution.

[0007] A dust suppression spraying device for road construction includes:

[0008] The main body and the spraying mechanism mounted on the main body;

[0009] The main body is fixed to the top of the construction fence and includes:

[0010] A water supply channel is located inside the main body and is used to connect to a water spray pipe to supply water to the interior of the main body;

[0011] The spraying mechanism includes:

[0012] The spray head is located on the top of the main body;

[0013] A connector is disposed on the top of the main body, the top of the connector extending into the spray head and rotatably connected to the spray head;

[0014] A connecting component is fixedly connected to the bottom of the connector and threaded into the interior of the main body, connecting the water supply channel and the connector.

[0015] Preferably, the main body further includes:

[0016] The slots, located on the top and sides of the main body, are used to provide grooves for accommodating the plastic cable ties.

[0017] Magnetic components are provided on both sides of the bottom of the main body to provide a magnetic fixation function for the main body.

[0018] Preferably, the spray head includes:

[0019] Spray holes are provided on both sides of the spray head. The two spray holes are symmetrical about the axis of the spray head and are located in the same vertical plane, and are used to spray water outward.

[0020] Spray tanks are located on both sides of the spray head and are symmetrical about the vertical plane where the two spray holes are located, and are used to spray water to the outside.

[0021] The first wind-driven component is fixedly connected to the bottom of the spray head and is configured to drive the spray head to rotate under the action of wind.

[0022] The second wind-driven component is fixedly connected to the bottom of the spray head and is configured to drive the spray head to rotate under the action of wind.

[0023] A chute is formed inside the spray head on one side near the connector.

[0024] Preferably, the connector includes:

[0025] A guide protrusion, fixed to the outside of the connector and extending into the groove, is used to guide the rotation of the spray head;

[0026] The protrusions, formed on the guide protrusions, extend upward and downward to prevent the spray head from detaching from the top of the connector.

[0027] Preferably, the second wind-driven component includes:

[0028] A force-reducing groove is formed on one side of the second wind-driven component and extends through the second wind-driven component to reduce the force-bearing area of ​​the second wind-driven component.

[0029] Preferably, the inner diameter area of ​​the spray hole is larger than the area of ​​the spray tank.

[0030] Preferably, the first wind-driven component, the second wind-driven component, and the spray hole are located in the same vertical plane.

[0031] Preferably, the main body is provided with a plurality of spraying mechanisms.

[0032] Preferably, the multiple bodies are connected by a water spray pipe.

[0033] This utility model provides a spray dust suppression device for road construction. Compared with the prior art, it has the following advantages:

[0034] 1. By setting a first wind-driven component and a second wind-driven component at the bottom of the spray head, the spray head is rotated by the wind force, so that the spray direction of the spray hole and spray trough can be dynamically adjusted with the wind direction, accurately covering the dust diffusion path. This solves the problem in the prior art that the fixed spray direction causes the water mist to not accurately cover the dust diffusion path, and improves the dust suppression effect of spraying.

[0035] 2. By setting the inner diameter area of ​​the spray hole to be larger than the area of ​​the spray tank, and by placing the first wind-driven component, the second wind-driven component, and the spray hole in the same vertical plane, the spray hole sprays a large amount of water in both the upwind and downwind directions. The water mist in the upwind direction forms a water curtain to intercept dust and prolong the collision time with the dust. The wind in the downwind direction pushes the water mist to expand the dust suppression range, thus avoiding the problem of poor dust suppression effect caused by a fixed spray direction and improving dust suppression efficiency.

[0046] Reference Figures 1-6 A dust suppression spraying device for road construction, comprising:

[0047] Main body 10 and spray mechanism installed on main body 10;

[0048] The main body 10 is fixed to the top of the construction enclosure and includes:

[0049] Water supply channel 11 is located inside the main body 10 and is used to connect with the water spray pipe to supply water to the interior of the main body 10;

[0050] The spray system includes:

[0051] Spray head 20 is located on the top of the main body 10;

[0052] The connector 26 is located at the top of the main body 10, and the top of the connector 26 extends into the spray head 20 and is rotatably connected to the spray head 20.

[0053] The connecting piece 27 is fixedly connected to the bottom of the connecting piece 26 and threadedly connected to the inside of the main body 10, connecting the water supply channel 11 and the connecting piece 26.

[0054] Furthermore, such as Figure 1 and Figure 2 As shown, water flows sequentially through the water spray pipe, water supply channel 11, connecting piece 27, and connecting piece 26 to the spray head 20, and is sprayed through the spray head 20 to complete the dust suppression work.

[0055] The main body 10 also includes:

[0056] Card slots 12 are provided on the top and sides of the main body 10 to provide slots for the plastic cable ties to accommodate themselves.

[0057] Magnetic components 13 are provided on both sides of the bottom of the main body 10 to provide the main body 10 with a magnetic fixation function.

[0058] Furthermore, two fixing methods are provided: one is flexible binding, which can adapt to different fence shapes and can be fixed by binding with plastic cable ties, ropes, etc.; the other is magnetic connection, which allows the main body 10 to be fixed to the sheet metal fence or the metal parts of the fence by magnetic components 13, so as to achieve quick and convenient installation of the main body 10.

[0059] The spray head 20 includes:

[0060] Spray holes 21 are provided on both sides of the spray head 20. The two spray holes 21 are symmetrical about the axis of the spray head 20 and are located in the same vertical plane, and are used to spray water outward.

[0061] Spray tanks 22 are located on both sides of spray head 20 and are symmetrical about the vertical plane where the two spray holes 21 are located, and are used to spray water to the outside.

[0062] The first wind-driven component 23 is fixedly connected to the bottom of the spray head 20 and is configured to drive the spray head 20 to rotate under the action of wind.

[0063] The second wind-driven component 24 is fixedly connected to the bottom of the spray head 20 and is configured to drive the spray head 20 to rotate under the action of wind.

[0064] The chute 25 is located inside the spray head 20 on one side near the connector 26.

[0065] Furthermore, such as Figures 3 to 6 As shown, without the need for an additional power source, the spray nozzle design and blade structure enable the spray head 20 to rotate under windy conditions by the rotation of the first wind-driven component 23 and the second wind-driven component 24, thereby adjusting the relative position of the spray nozzle 21 and the spray trough 22 to perform spraying work.

[0066] Connector 26 includes:

[0067] The guide protrusion 261 is fixed to the outside of the connector 26 and extends into the groove 25 to provide guidance for the rotation of the spray head 20;

[0068] The protrusion 262, formed on the guide protrusion 261, extends upward and downward to prevent the spray head 20 from detaching from the top of the connector 26.

[0069] Furthermore, such as Figure 6 As shown, the guide protrusion 261 ensures that the spray head 20 does not deviate when rotating, maintaining the regularity of the water spray direction, and the protrusion 262 prevents the spray head 20 from falling off due to excessive wind or vibration, ensuring the safety of the device.

[0070] The second wind-powered drive component 24 includes:

[0071] The force-reducing groove 241 is formed on one side of the second wind-driven component 24 and extends through the second wind-driven component 24, and is used to reduce the force-bearing area of ​​the second wind-driven component 24.

[0072] Furthermore, such as Figures 3 to 5 As shown, the force-bearing area of ​​the second wind-driven component 24 is reduced, so that the force-bearing areas of the first wind-driven component 23 and the second wind-driven component 24 are different under the action of wind, which facilitates the rotation of the spray head 20.

[0073] The inner diameter area of ​​spray hole 21 is larger than the area of ​​spray tank 22.

[0074] Furthermore, the spray volume of the spray hole 21 is greater than that of the spray trough 22, that is, the spray volume of the spray mechanism in the upwind and downwind directions is greater than the spray volume in other directions.

[0075] The first wind-driven component 23, the second wind-driven component 24, and the spray hole 21 are all located in the same vertical plane.

[0076] Furthermore, such as Figures 3 to 5 As shown, the spray directions of the two spray nozzles 21 are respectively against the wind and with the wind. Spraying from the nozzle 21 against the wind, the water mist is opposite to the wind direction, forming a water curtain before the dust is blown towards the target area, directly intercepting dust particles. Simultaneously, the wind hinders the water mist's movement, causing it to remain in the air longer and increasing the probability of collision with dust. The spray nozzle 21 on the other side sprays with the wind, and the wind propels the water mist forward, transporting it to a farther area and expanding the dust suppression range.

[0077] Several spraying mechanisms are installed on the main body 10.

[0078] Furthermore, such as Figure 1 and Figure 2 As shown, each mechanism sprays water independently and rotates to form a composite spray area, improving the dust suppression effect.

[0079] Multiple main bodies 10 are connected by water spray pipes.

[0080] Furthermore, the dispersed main bodies 10 are connected into a whole, and the flexible nature of the water spray pipe is utilized to allow multiple main bodies 10 to be arranged into different shapes under the connection of the water spray pipe, which is suitable for dust suppression work on various road sections.

[0081] Working process and principle: When this road construction dust suppression spraying device is working, water enters the water supply channel 11 inside the main body 10 through the spray pipe, flows into the connector 26 through the connector 27, and then enters the top spray head 20. It is sprayed out from the spray holes 21 and spray channels 22 on both sides of the spray head 20 to achieve dust suppression. The device is driven by wind. Due to the different force-bearing areas of the first wind-driven component 23 and the second wind-driven component 24 at the bottom of the spray head 20, water is sprayed in the downwind direction by the spray hole 21 on the side of the first wind-driven component 23 and in the upwind direction by the other spray hole 21 on the side of the second wind-driven component 24. When the spray hole 21 sprays in the upwind direction, the water mist forms a water curtain to intercept dust. The wind force hinders the water mist from moving forward, increasing the probability of collision with dust. When the spray hole 21 on the other side sprays in the downwind direction, the wind force pushes the water mist to expand the dust suppression range. During this process, due to changes in wind force, the spray head 20 rotates back and forth within a certain angle under changing force, further expanding the spray range of the spray holes 21 on both sides and improving the dust removal effect.
