Description

Technical Field

[0001] This utility model belongs to the technical field of blasting auxiliary equipment, specifically relating to a dust reduction device used in landslide geological disasters. Background Technology

[0002] Landslides, as a type of geological phenomenon characterized by their suddenness and destructiveness, often pose a serious threat to people's lives and property, as well as infrastructure construction. In emergency rescue or engineering management of landslide sites, blasting technology is frequently used to actively break up unstable rock masses and reduce the risk of subsequent disasters. However, the blasting process inevitably generates a large amount of high-concentration rock debris dust instantly. These dust particles are extremely fine and have a very strong diffusion capacity, rapidly spreading in all directions under the influence of natural wind. Although ordinary spraying is currently commonly used for dust suppression, existing equipment often faces challenges in the high-impact, high-diffusion, and space-constrained environment of landslide blasting sites. These challenges include limited coverage, numerous dust suppression dead zones, susceptibility to damage from flying debris, and easy blockage of key nozzles by falling rocks. Consequently, the suppression effect and protective performance are insufficient to meet the requirements for efficient and safe dust control. Utility Model Content

[0023] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0024] This utility model provides a dust suppression device for use in landslide geological disasters, such as Figures 1-4As shown, the device includes a multifaceted shell, a main body 2, a drainage pipe 3, several first branch pipes 4, and six wide-angle nozzles 5. The multifaceted shell includes a flat top plate, several side walls 12 extending obliquely downward from the periphery of the top plate, and a bottom opening 13 formed by the bottom edge of the side walls 12, forming a tortoise-shell-like shell structure with six oblique surfaces. The main body 2 is located in the middle of the multifaceted shell and is fixed to the inside of the multifaceted shell by six connecting rods. One end of the drainage pipe 3 is connected to the main body 2, and the other end is connected to a... The water source includes a first branch pipe 4, one end of which is connected to the main pipe 2, and the other end of which is connected to the wide-angle nozzle 5. The wide-angle nozzle 5 extends from the side wall 12 and is perpendicular to the side wall 12. It also includes a photovoltaic panel 61, an energy storage module 7 electrically connected to the photovoltaic panel 61, and several first electrically controlled water valves 62 that can be remotely controlled. The photovoltaic panel 61 is attached to the outside of the top plate. The energy storage module 7 supplies power to the first electrically controlled water valves 62. Each first branch pipe 4 is equipped with a first electrically controlled water valve 62.

[0025] This utility model, by setting up multiple wide-angle nozzles 5 that spray water in all directions during the blasting process of landslide geological disasters, can promptly trap and deposit the generated dust over a wide area by spraying water mist, reducing the spread of dust. This device is easy to connect and arrange by directly connecting to a pressurized water source. The multi-faceted shell in the shape of a tortoise shell effectively prevents damage to the internal water pipe structure by flying stones and other debris. The sloping protective surface can prevent excessive accumulation of gravel at the wide-angle nozzles 5, avoiding clogging. This device is easy to arrange and has a significant dust suppression effect. Its dust suppression spraying operation can also be controlled by a first electrically controlled water valve 62, which is powered by a photovoltaic panel 61, eliminating the need for an additional power supply.

[0026] In further proposals, such as Figure 3 and Figure 4 It also includes a protective component and several second electrically controlled water valves 63. The protective component includes several second branch pipes 81, each of which is provided with a second electrically controlled water valve 63. The power storage module 7 supplies power to the second electrically controlled water valves 63. The second branch pipes 81 are connected to the main pipe 2. The ends of the second branch pipes 81 extend from the side wall 12 and open toward the wide-angle nozzle 5.

[0027] In this structure, by opening the second branch pipe 81 through the second electrically controlled water valve 63, water is sprayed out through the second branch pipe 81 to flush the wide-angle nozzle 5, thereby clearing away gravel and dust around the wide-angle nozzle 5 and further preventing blockage.

[0028] In further proposals, such as Figure 3 and Figure 4The protective assembly further includes a turntable 82, a rotating cylinder 83, and a drive gear 84. The rotating cylinder 83 is coaxially and rotatably disposed in the middle section of the second branch pipe body 81. The second branch pipe body 81 is divided into a front section and a rear section by the rotating cylinder 83. The front section and the rear section are connected and fixed by a fixing bracket 86. A spiral blade 831 is integrally formed on the inner side of the rotating cylinder 83. The drive gear 84 is coaxially disposed on the outer side of the rotating cylinder 83. The turntable 82 is rotatably disposed on the side wall 12 and rotates around the wide-angle spray nozzle. Around the mouth 5, a number of retaining ridges are fixedly provided on the surface of the turntable 82. A circular hole is opened on the side wall 12 for the turntable 82 to pass through. The inner diameter of the circular hole is larger than the outer diameter of the turntable 82. The turntable 82 is located at the circular hole and is flush with the side wall 12. The drive tooth 84 meshes with the outer side of the turntable 82. The protective assembly also includes a cylindrical seat 85 surrounding the first branch pipe body 4. The cylindrical seat 85 is fixed on the connecting rod by a support member. The turntable 82 is coaxially rotatably mounted on the cylindrical seat 85.

[0029] In this structure, when gravel and dust block any wide-angle nozzle 5, all first electrically controlled water valves 62 can be closed, and the water flow in the second branch pipe 81 on the blocked wide-angle nozzle 5 can be opened. The water flow with higher pressure passes through the second branch pipe 81, driving the rotating drum 83 on the second branch pipe 81 to rotate. The rotating drum 83 drives the rotating disk 82 to rotate. The rotation of the rotating disk 82 effectively transfers the gravel and dust blocking the wide-angle nozzle 5. In addition, with the flushing of the water flow, the debris around the wide-angle nozzle 5 can be quickly carried away. This structure helps to keep the spray nozzles of each wide-angle nozzle 5 of the entire device unobstructed, so that the device can maintain the function of spreading water mist to reduce dust in all directions.

[0030] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
