Description

Technical Field

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

[0002] During construction, dust suppression devices are installed on-site to reduce dust pollution. One existing dust suppression device has a water-carrying pipe with atomizing nozzles at the top. Water is sprayed out in atomized form through a booster pump and atomizing nozzles, which can reduce dust pollution on the construction site. However, the pipe is too long, making it inconvenient to move and transport, and the height of the pipe cannot be adjusted. This means that the range of the water mist cannot be adjusted. If the water mist range is too large, it may affect pedestrians outside the construction site. If the water mist range is too small, it will increase the amount of equipment used and make it difficult to meet the needs. Utility Model Content

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0018] like Figure 1-6 As shown, a dust suppression device for construction includes: Pumping pressurization section; The spray section and the pumping and pressurizing section are used to draw in external water, pressurize the water, and then spray water mist outward through the spray section. The telescopic section and the spray section are located at the upper end of the telescopic section. The telescopic section can extend and retract, and the spray height of the spray section can be controlled by extending and retracting the telescopic section. The moving part and the pumping and pressurizing part are mounted on the moving part, and the moving part can drive the pumping and pressurizing part to move.

[0019] Furthermore, the pump pressurization unit includes a cabinet 1, a handle 2 is provided on the side of the cabinet 1, and a booster water pump is provided inside the cabinet 1. The booster water pump has an inlet port 3 and an outlet port.

[0020] When using this device, an external water source is required. The external water pipe is connected to the inlet port 3 of the booster pump, which can spray water at an appropriate pressure.

[0021] Furthermore, the telescopic part includes a base plate 4, which is rotatably connected to the cabinet 1. A U-shaped groove is provided on one side of the base plate 4. A stud 5 is provided on the cabinet 1, and a screw cap 6 is also provided that is threadedly connected to the stud 5. Several telescopic elements are provided on the base plate 4. The telescopic elements include at least two cylinders 7. Except for the innermost cylinder 7, each cylinder 7 has two guide grooves inside. The guide grooves include a top groove 8, a middle groove 9, and a bottom groove 10 arranged in sequence. The bottom groove 10 is horizontally arranged, and the top groove 8 is inclined downward. Except for the outermost cylinder 7, each cylinder 7 has two protrusions 11 that cooperate with the guide grooves. Except for the outermost cylinder 7, each cylinder 7 has a friction ring 12 at its upper end. The spray part is located on the friction ring 12 of the innermost cylinder 7.

[0022] When the base plate 4 is flipped from the side of the cabinet 1 to the top surface of the cabinet 1, the stud 5 on the cabinet 1 is located inside the U-shaped groove. The user can fix the base plate 4 to the top surface of the cabinet 1 by threading the nut 6 to the stud 5.

[0023] After fixing the base plate 4, the height of the top spray section needs to be raised. Specifically, when raising the height of the spray section, the user first holds the friction ring 12 located at the top with both hands, and then rotates the friction ring 12 to move the protrusion 11 from the bottom groove 10 to the middle groove 9. When the protrusion 11 abuts against the middle groove 9, the friction ring 12 can no longer rotate. Then the user controls the friction ring 12 and the cylinder 7 connected to the friction ring 12 to move upward. When the protrusion 11 moves upward to the top of the middle groove 9, the cylinder 7 can no longer move upward. The user continues to control the rotation of the cylinder 7 through the friction ring 12 to make the protrusion 11 enter the top groove 8. Since the top groove 8 is inclined, when the protrusion 11 enters the lowest point of the top groove 8, the height of the cylinder 7 will decrease slightly, thereby improving the stability of the cylinder 7. Then, the remaining cylinders 7 are raised from the inside to the outside in sequence, thereby continuously raising the height of the spray section. When the spray section rises to a suitable height, the raising of the remaining cylinders 7 is stopped.

[0024] The cylinder body 7 is made of aluminum alloy to reduce the weight of the telescopic part and make it easier for users to use. The friction ring 12 is made of rubber and is fixed to the outer upper end of the cylinder body 7 with glue.

[0025] When the cylinder 7 is flipped from the top of the cabinet 1 to the side of the cabinet 1, the protrusion 11 on the cylinder 7 is located in the bottom groove 10 in the guide groove, thereby preventing the cylinder 7 from separating from the cylinder 7.

[0026] Furthermore, the spray unit includes a fixed cylinder 13 mounted on the friction ring 12, a mounting plate 14 fixedly connected to the fixed cylinder 13, a motor 15 mounted on the mounting plate 14, a movable plate 21 rotatably connected to the fixed cylinder 13, and a transmission assembly 22 transmitting power between the movable plate 21 and the output end of the motor 15. An atomizing nozzle 16 is mounted on the movable plate 21. Both the base plate 4 and the movable plate 21 have through holes. The unit also includes a water pipe 17, one end of which is connected to the outlet port of the booster water pump, and the other end of which is connected to the atomizing nozzle 16.

[0027] When performing dust suppression operations at the construction site, the atomizing nozzle 16 is first raised to a suitable height, and then the booster water pump is started. The booster water pump pressurizes the water and delivers it to the atomizing nozzle 16 through the water pipe 17. The water is then sprayed outward in the form of water mist through the atomizing nozzle 16. Then the motor 15 is started. The motor 15 drives the movable plate 21 to rotate through the transmission component 22. When the movable plate 21 rotates, it can drive the atomizing nozzle 16 to rotate. The water pipe 17 is connected to the atomizing nozzle 16 through a rotary joint to ensure that the atomizing nozzle 16 can rotate 360°, while the water pipe 17 does not need to rotate. By continuously rotating the atomizing nozzle 16, the device can cover a larger working area. The rotation speed of the atomizing nozzle 16 is about 8 seconds per second.

[0028] The transmission component 22 can be a synchronous pulley, a synchronous belt drive, a gear drive, or a sprocket and chain drive.

[0029] When the spray direction of the atomizing nozzle 16 is located directly above and near the motor 15, the movable plate 21 can block the sprayed atomized water, thereby preventing a large amount of water from flowing onto the motor 15, and the motor 15 must be waterproof.

[0030] Both the motor 15 and the booster pump are controlled by a controller.

[0031] Furthermore, the movable part includes a carrying plate 18, the cabinet 1 is mounted on the carrying plate 18, the lower surface of the carrying plate is provided with rollers 19, and one side of the carrying plate is provided with a receiving groove 20.

[0032] The receiving slot 20 facilitates the storage of the telescopic part and the spraying part.

[0033] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
