Abstract
Description
Technical Field
[0001] This invention relates to the field of dust suppression equipment, and in particular to a dust suppression device for construction sites. Background Technology
[0002] Because of the large number of freight trucks and construction waste trucks passing by construction sites every day, a large amount of dust is generated at the construction sites. Construction site dust is one of the main reasons for the deterioration of urban air quality. Controlling and eliminating construction site dust has become an important issue in the management of urban construction sites.
[0003] Dust suppression devices in related technologies typically include a support frame with atomizing nozzles mounted on it. The water inlet of each nozzle is connected to a water inlet pipe, which is then connected to an external water supply pipe. Water is supplied to the inlet pipe via the external water supply pipe, and the clean water is atomized and sprayed out through the atomizing nozzles to achieve dust suppression.
[0004] However, most of the atomizing nozzles in the dust suppression devices of related technologies spray water mist in a specific direction, which limits the spray area. Workers need to constantly adjust the direction of the atomizing nozzles to achieve large-area dust suppression operations, which is not only cumbersome to operate, but also increases the burden on workers and needs to be improved.

[0021] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be arbitrarily combined with each other.
[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 The illustration shows an embodiment of the present invention, which discloses a construction site dust suppression device, including a support frame 1. Self-locking casters 2 are respectively installed at the four corners of the bottom of the support frame 1 to facilitate movement of the support frame 1 by workers. A support pipe 3 is vertically installed on the support frame 1, and the support pipe 3 is rotatably connected to the support frame 1 via bearings. A support base 4 is installed at the top of the support pipe 3, and an atomizing nozzle 5 is installed on the support base 4. The top of the support pipe 3 is connected to the water inlet end of the atomizing nozzle 5 via a water pipe 6.
[0023] Reference Figure 1 , Figure 2 The bottom of the support pipe 3 is provided with a water inlet connector 7. The water inlet connector 7 is rotatably connected to the support pipe 3 through a sealed bearing. A water inlet pipe 8 is connected to the water inlet connector 7, and the water inlet pipe 8 is used to connect to an external water supply pipe. At the same time, the support frame 1 is provided with a control component 9 for controlling the rotation of the support pipe 3.
[0024] Clean water supplied by the external water supply pipe enters the inlet connector 7, support pipe 3, and water pipe 6 sequentially through the inlet pipe 8. The clean water is then atomized and sprayed out through the atomizing nozzle 5. At the same time, the support pipe 3 is controlled by the control component 9 to rotate the support base 4 and the atomizing nozzle 5, thereby adjusting the spray angle of the atomizing nozzle 5, increasing the spray area, and thus improving the dust suppression effect.
[0025] Reference Figure 1 , Figure 2 , Figure 3The control component 9 includes a control box 91 fixed to the support frame 1. A support tube 3 passes through the control box 91 and is rotatably connected to the control box 91 via a sealed bearing. A control impeller 92 is fixedly fitted onto the portion of the support tube 3 inside the control box 91. A water supply pipe 93 is connected to one side of the control box 91, and a water outlet pipe 94 is connected to the other side. The water supply pipe 93 is connected to the inlet pipe 8, and the water outlet pipe 94 is connected to the inlet connector 7. The water supply pipe 93 and the water outlet pipe 94 are staggered, and the clean water sprayed from the water supply pipe 93 can impact the blades of the control impeller 92, causing the control impeller 92 to drive the support tube 3 to rotate.
[0026] When clean water flows through the inlet pipe 8, some of it enters the control box 91 through the supply pipe 93. At this time, the water sprayed from the supply pipe 93 impacts the blades of the control impeller 92, causing it to rotate the support pipe 3 and the atomizing nozzle 5. The clean water then enters the support pipe 3 through the outlet pipe 94 and is supplied to the atomizing nozzle 5. This design allows the atomizing nozzle 5 to rotate automatically, eliminating the need for manual adjustment and thus automating the spray angle adjustment, reducing the workload for operators.
[0027] Reference Figure 1 , Figure 2 , Figure 3 A solenoid valve 10 is installed on the water supply pipe 93, and the solenoid valve 10 is used to control the opening and closing of the water supply pipe 93. At the same time, a limiting member 11 is installed on the support frame 1 to limit the rotation of the support pipe 3. The limiting member 11 includes a limiting gear 111 fixedly sleeved on the support pipe 3, a limiting rack 112 horizontally slidably connected on the support frame 1, and a hydraulic cylinder 113 is installed on the support frame 1 to control the horizontal sliding of the limiting rack 112, so that the limiting rack 112 can engage or disengage with the limiting gear 111.
[0028] When the operator needs to spray water mist in a specific direction, rotating the atomizing nozzle 5 drives the support tube 3 and other components to rotate until the atomizing nozzle 5 reaches the desired spray angle. Then, the hydraulic cylinder 113 controls the limiting rack 112 to move towards the limiting gear 111 until the limiting rack 112 engages with the limiting gear 111, thus locking the support tube 3. Subsequently, the solenoid valve 10 is closed to prevent clean water from entering the control box 91 through the water supply pipe 93. At this point, the atomizing nozzle 5 can spray water mist in the specific direction.
[0029] Reference Figure 1 , Figure 3The water pipe 6 is made of corrugated pipe, meaning it can be bent. Two hinge shafts 12 are symmetrically fixedly connected to the atomizing nozzle 5, and each hinge shaft 12 is hinged to the support base 4. At the same time, the water inlet connector 7 and the support pipe 3 are equipped with adjusting components 13, which are used to adjust the water flow rate of the support pipe 3 so that the atomizing nozzle 5 can swing vertically under water pressure.
[0030] Reference Figure 3 , Figure 4 The adjusting component 13 includes a first adjusting ring 131 fixed inside the water inlet connector 7. Multiple first adjusting holes 132 are provided through the first adjusting ring 131, and the multiple first adjusting holes 132 are arranged at equal intervals along the circumference of the first adjusting ring 131. A second adjusting ring 133 is fixedly connected to the bottom of the support pipe 3. The second adjusting ring 133 is aligned with the first adjusting ring 131, and the inner diameters of the first adjusting ring 131 and the second adjusting ring 133 are the same. Simultaneously, multiple second adjusting holes 134 are provided through the second adjusting ring 133. The number and inner diameter of the multiple second adjusting holes 134 are the same as those of the multiple first adjusting holes 132, and the multiple second adjusting holes 134 can be aligned or misaligned with the multiple first adjusting holes 132.
[0031] As the support tube 3 rotates, multiple first adjustment holes 132 and multiple second adjustment holes 134 are repeatedly aligned and misaligned to change the flow rate of clean water entering the support tube 3 in real time. At this time, the atomizing nozzle 5 can swing vertically under the combined action of water pressure and its own gravity. That is, the atomizing nozzle 5 can swing vertically while rotating, further increasing the spray area of the atomizing nozzle 5 and thus improving the dust suppression effect.
[0032] Reference Figure 3 , Figure 5 The support base 4 is provided with two locking elements 14, which are used to restrict the rotation of the corresponding hinge shaft 12. When the staff needs the atomizing nozzle 5 to spray in a specific direction, the locking elements 14 can be used to limit the corresponding hinge shaft 12 so that the staff can use the dust suppression device according to actual needs.
[0033] Reference Figure 3 , Figure 5Each locking component 14 includes a locking disc 141, a locking screw 142, and multiple locking slots 143. The locking disc 141 is fixedly sleeved on the corresponding hinge shaft 12, the locking screw 142 is threadedly connected to the corresponding locking disc 141, and the multiple locking slots 143 are respectively disposed on the support base 4. The multiple locking slots 143 are arranged at equal intervals along the circumference of the corresponding locking disc 141, and the locking screw 142 can be threadedly connected to any locking slot 143. This locking component 14 can not only fix the atomizing nozzle 5, but also fix the atomizing nozzle 5 in multiple positions to improve the angle adjustment range of the atomizing nozzle 5.
[0034] Reference Figure 2 , Figure 4 The water inlet connector 7 and the support pipe 3 are respectively equipped with marking lines 15. When the two marking lines 15 are aligned, the multiple first adjustment holes 132 and multiple second adjustment holes 134 are aligned one by one, so as to facilitate the staff to confirm whether the water inlet connector 7 and the support pipe 3 are connected and to ensure the maximum water inlet, thereby improving practicality.
