Description

Technical Field

[0001] This utility model relates to the field of dust removal technology, and more specifically, to a water curtain dust suppression device for tunnels. Background Technology

[0002] During tunnel construction, the dust generated poses a serious threat to the construction site environment and the health of workers. In order to effectively reduce dust pollution, water curtain dust suppression devices have emerged. Water curtain dust suppression devices use high-pressure water mist to form a water curtain, which effectively adsorbs and settles dust particles in the air, thereby significantly improving the working environment.

[0003] Traditional water curtain dust suppression devices for tunnel blasting mostly adopt a fixed structure design, and the support brackets for the nozzles lack flexibility. Once installed, they are difficult to adjust in shape. This means that after completing the dust suppression task, the device often occupies a large space, making it inconvenient to transport and store. Therefore, we have made an improvement and proposed a water curtain dust suppression device for tunnels. Utility Model Content

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0027] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] For an example, please refer to... Figures 1-3A water curtain dust suppression device for tunnels includes a water storage tank 1 and a dust suppression structure installed on the water storage tank 1. The dust suppression structure includes a support pipe 2 installed inside the water storage tank 1. A support rod 201 is inserted and connected to the inner wall of the support pipe 2. A support base 203 is fixedly connected to the top of the support rod 201. Two support shafts 204 are connected to the support base 203 via bearings. A conveying pipe 205 is fixedly sleeved on the outer surface of each of the two support shafts 204. Several nozzles 206 are connected to each of the two conveying pipes 205. The support base 203 and the support rod 201 are also included. A control component is provided between 01 and the two support shafts 204. The support rod 201 and the support tube 2 can support the support base 203. The support rod 201 can be raised and lowered inside the support tube 2. The conveying tube 205 is connected through the support shaft 204 and can be rotated. After the dust suppression structure is used, it can be folded and stored in the water tank 1 to reduce the overall volume, making it convenient for transportation and storage. During transportation and storage, the dust suppression device is protected by the water tank 1 and is not easily damaged by bumps.

[0030] Furthermore, such as Figures 1-3 As shown, the control component includes a groove 208 formed on the top of the support rod 201. A slider 209 is slidably connected in the groove 208. A rack 211 is fixedly installed on the top of the slider 209. Gears 212 mesh on both sides of the rack 211. The two gears 212 are respectively fixedly sleeved on the outer surfaces of the two support shafts 204. During the lifting and lowering process, the gears 212 can drive the gears 212 to rotate. During the rotation of the gears 212, the conveying pipe 205 can be rotated.

[0031] Furthermore, such as Figures 1-3 As shown, a second hand-tightening bolt 210 is threaded onto the support base 203. The bottom end of the second hand-tightening bolt 210 extends into the slide groove 208 and is connected to the top of the slider 209 through a bearing. By rotating the second hand-tightening bolt 210, the slider 209 can be driven to rise and fall, which in turn can drive the rack 211 to rise and fall.

[0032] Furthermore, such as Figure 2 As shown, a first hand-tightening bolt 202 is threadedly connected to the side of the support tube 2. One end of the first hand-tightening bolt 202 is inserted into the support tube 2 and contacts the side of the support rod 201. The position of the support rod 201 can be fixed by the first hand-tightening bolt 202.

[0033] Furthermore, a conveying component is provided between the two conveying pipes 205, which is used to convey the water stored in the water storage tank 1 to the conveying pipe 205.

[0034] Furthermore, such as Figure 2As shown, the conveying component includes two hoses 207, the top ends of which are connected to two conveying pipes 205 respectively, and a T-pipe is connected between the bottom ends of the two hoses 207. The T-pipe is connected to a water pump located in the water storage tank 1. The water pump can convey water in the water storage tank 1 to the conveying pipe 205 through the T-pipe and hoses 207, so that the water is sprayed out from the nozzle 206.

[0035] Furthermore, such as Figure 1 As shown, the top of the water storage tank 1 is hinged to a first tank cover 101, and the first tank cover 101 is hinged to a second tank cover 102. During transportation and storage, the top of the water storage tank 1 can be sealed by the first tank cover 101 and the second tank cover 102, thereby enabling the water storage tank 1, the first tank cover 101 and the second tank cover 102 to protect the dust suppression structure.

[0036] Furthermore, such as Figure 1 As shown, the bottom of the water storage tank 1 is equipped with several wheels 105, which facilitates the overall movement.

[0037] Furthermore, such as Figure 1 As shown, a handrail 103 is fixedly installed on the side of the water tank 1. The handrail 103 is used to provide a grip point for the hands when the whole body moves.

[0038] Furthermore, such as Figure 1 As shown, the water storage tank 1 is connected to a drain pipe 104, and a valve is installed on the drain pipe 104. The drain pipe 104 is used to drain the water in the water storage tank 1.

[0039] The usage process of the water curtain dust suppression device for tunnels provided by this utility model is as follows:

[0040] Reference Figure 1 Water is injected into the water storage tank 1. The water pump, through the three-way pipe and hose 207, can transport the water in the water storage tank 1 to the delivery pipe 205, so that the water is sprayed out from the nozzle 206. After use, the valve on the drain pipe 104 is opened to drain the water in the water storage tank 1. The second hand-tightening bolt 210 is turned so that the slider 209 drives the rack 211 to rise, so that the gear 212 drives the delivery pipe 205 to rotate downward until it is parallel to the support rod 201. After loosening the first hand-tightening bolt 202, the support rod 201 is pushed downward so that the dust suppression structure is completely stored in the water storage tank 1. The first tank cover 101 and the second tank cover 102 are then closed, and the dust suppression structure is fully housed in the water storage tank 1. Figure 4 As shown;

[0041] When using it again, open the second cover 102 and the first cover 101, pull the support rod 201 upward to raise the support base 203, tighten the first hand-tightening bolt 202 to fix the position of the support rod 201, rotate the second hand-tightening bolt 210 to make the slider 209 drive the rack 211 to descend, so that the gear 212 drives the conveying pipe 205 to rotate upward until it is perpendicular to the support rod 201, close the first cover 101, and open the second cover 102, as shown. Figure 1 As shown.
