However, to achieve a good dust suppression effect, a large number of water trucks are usually needed around the building, which is very costly. Therefore, designing a low-cost dust suppression device for building demolition has become an urgent problem to be solved. Summary of the Invention

[0006] By adopting the above technical solution, during the building demolition process, several dust suppression devices are installed around the building and connected to an external water source. The dust suppression devices release a water curtain towards the building, and during the demolition, the water curtain will shield the dust, thereby reducing the impact of dust on the surrounding environment.

[0018] By adopting the above technical solution, a ring of dust suppression equipment is set up around the building and connected to an external water source.

[0024] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be described in further detail below.

[0025] A dust suppression device for building demolition, referring to Figure 1 It includes a water pipe 1, which has an inlet 111 and an outlet 121. The water pipe 1 includes a vertically arranged main body 11 and an inclined part 12.

[0026] The bottom of the main body 11 is fixedly connected to a base 2 for fixing the main body 11 to the ground. The base 2 specifically includes a seat body 21 and a number of positioning pins 22. The seat body 21 has a number of positioning holes 211. The number of positioning holes 211 are evenly arranged around the axis of the seat body 21 along the edge of the seat body 21, and the number of positioning pins 22 correspond one-to-one with the number of positioning holes 211. The positioning pins 22 pass through the positioning holes 211.

[0027] An inclined portion 12 is provided at the top of the main body portion 11 and is connected to the main body portion 11. The inlet 111 is located at the bottom of the main body portion 11, and the outlet 121 is located at the end of the inclined portion 12 away from the main body portion 11. A nozzle 3 is installed at the outlet 121.

[0028] Before demolishing the building, several dust suppression devices are installed around its perimeter. The inclined parts 12 of these devices face the building, and the devices are connected to an external water source. At this time, the nozzles 3 spray a water curtain towards the building. Then, the building is demolished by blasting. As the dust generated by the blast spreads outward, the water curtain released by the dust suppression devices can block the dust, thus achieving the purpose of dust suppression. Furthermore, compared to using water trucks, the dust suppression devices can significantly reduce operating costs.

[0029] Furthermore, the inclined part 12 is hinged to the main body 11, and the inclined part 12 and the main body 11 are connected by a flexible hose 13. An adjustment mechanism is provided between the inclined part 12 and the main body 11. The inclined part 12 can be rotated up and down through the adjustment mechanism, thereby changing the tilt angle of the inclined part 12. This allows the dust suppression equipment to spray water onto the building at different angles, thus enabling the dust suppression equipment to adapt to different working conditions (such as the demolition of buildings of different heights).

[0030] Specifically, the adjustment mechanism includes a base 4 and an adjustment element 5.

[0031] Reference Figure 2 The base 4 is installed on the top of the main body 11 and is located directly below the inclined part 12; the adjusting member 5 is a threaded member that passes vertically through the base 4 and is threadedly connected to the base 4.

[0032] The inclined portion 12 is provided with a slide 122, which is arranged along the axial direction of the inclined portion 12. The slide 122 can be a channel steel with a dovetail-shaped cross section fixed to the inclined portion 12. In this embodiment, in order to save space occupied by the slide 122, the slide 122 is a groove opened to the surface of the inclined portion 12, and the cross section of the slide 122 is dovetail-shaped.

[0033] Reference Figure 3A sliding member 6, adapted to the slide rail 122, is slidably connected within the slide rail 122. The top end of the adjusting member 5 is rotatably connected to the sliding member 6. Specifically, the sliding member 6 has a connecting groove 61 with a "T"-shaped cross-section. The top end of the adjusting member 5 is fixedly connected to a rotating member 51 adapted to the connecting groove 61, and the rotating member 51 is slidably connected within the connecting groove 61.

[0034] By rotating the adjusting member 5, the top of the adjusting member 5 can be raised or lowered, thereby causing the sliding member 6 to slide within the slide rail 122, thus changing the tilt angle of the tilting part 12.

[0035] Furthermore, in order to increase the angle adjustment range of the tilting part 12.

[0036] Reference Figure 2 The base 4 includes a support part 41, an adjustment part 42, and a foundation part 43.

[0037] One end of the support portion 41 is hinged to the main body portion 11, and the end of the support portion 41 away from the main body portion 11 is hinged to one end of the adjustment portion 42. The support portion 41 is provided with a mounting hole 411, the base portion 43 is rotatably connected to the mounting hole 411, and the adjustment member 5 is installed to the base portion 43.

[0038] The adjustment mechanism also includes an adjustment assembly 7, which includes a fixed base 71 and an adjustment member 72. The fixed base 71 is fixed to the main body 11 and is located directly below the adjustment part 42. The adjustment member 72 passes vertically through the fixed base 71, and the adjustment member and the fixed base 71 are connected by a thread.

[0039] Reference Figure 4 The top of the adjusting member 72 is rotatably connected to the intermediate member 73. Specifically, the intermediate member 73 is provided with a connecting groove 731 with a cross-section of "T". The corresponding adjusting member 72 is fixedly connected to a rotating member 721 that is adapted to the connecting groove 731. The rotating member 721 is slidably connected to the connecting groove 731.

[0040] The end of the adjusting part 42 away from the bearing part 41 is hinged to the intermediate part 73.

[0041] By turning the adjusting part 2 72, the height of the base part 43 can be changed, thereby changing the adjustment range of the angle of the tilt part 12.

[0042] Reference Figure 2 Furthermore, a limiting component 8 is provided between the base part 43 and the main body part 11. The limiting component 8 includes a telescopic member 81 and a sliding member 82. A track 112 is vertically provided on the main body part 11. The track 112 can be a channel steel with a dovetail-shaped cross-section. In this embodiment, the track 112 can also be a groove opened to the surface of the main body part 11, and the cross-section of the groove is dovetail-shaped.

[0043] The sliding member 82 is a block adapted to the track 112, and the sliding member 82 is slidably connected to the track 112. The telescopic member 81 is horizontally disposed between the sliding member 82 and the base part 43, and both ends of the telescopic member 81 are fixedly connected to the sliding member 82 and the base part 43 respectively.

[0044] The cooperation of the telescopic component 81 and the sliding component 82 can limit the base part 43. During the adjustment of the height of the base part 43, the adjusting component 5 can be kept as vertical as possible, and the adjusting component 5 can be more stable when supporting the inclined part 12.

[0045] To facilitate the screwing of the adjusting component 5, a polygonal adjusting groove 52 is provided at the bottom of the adjusting component 5. During the screwing process, tools such as screwdrivers can be used to screw the adjusting component 5.

[0046] To facilitate the turning of the adjusting part 72, a polygonal adjusting groove 722 is provided at the bottom of the adjusting part 72. During the turning of the adjusting part 72, tools such as screwdrivers can be used to turn the adjusting part 72.

[0047] The adjustment part 42 is provided with an elongated relief hole 421. During the process of turning the adjustment part 5, since the dust removal equipment is relatively tall, tools such as screwdrivers can be fixed to external tools such as long rods, and then pass through the relief hole 421 and abut into the adjustment groove 52, thereby making it easier to turn the adjustment part 5.

[0048] Branch pipes 1112 are provided on both sides of the main body 11. Sprinklers are provided on the end of the branch pipe 1112 away from the main body 11, the side of the branch pipe 1112 facing the building, and the upper and lower sides of the branch pipe 1112.

[0049] By installing a ring of dust suppression equipment around the building and connecting it to an external water source, a water curtain will be formed between the dust suppression equipment, preventing the spread of dust and thus improving the dust suppression effect.

[0050] The implementation principle of this application embodiment is as follows: Before demolishing a building by blasting, multiple dust suppression devices are first installed around the building. The tilt angle of the inclined section 12 on the dust suppression device is adjusted according to the building's height via an adjustment mechanism. Then, the dust suppression device is connected to an external water source, and the nozzles 3 on the dust suppression device spray a water curtain. Afterward, the building is demolished by blasting, and the dust suppression device blocks the dust generated during the demolition process, thus achieving the effect of dust suppression.

[0051] A method for dust suppression during building demolition includes the following steps: S1. Install the first ring of dust suppression equipment around the building.

[0052] The first ring of dust suppression equipment includes several dust suppression devices, and the distance between the dust suppression devices in the first ring and the building is 40m + 0.2*X, where X is the building height, and the angle between the inclined part 12 and the main body 11 of the dust suppression devices in the first ring is 120°.

[0053] S2. Set up a second ring of dust suppression equipment around the first ring of dust suppression equipment.

[0054] The distance between the dust suppression equipment in the second ring and the dust suppression equipment in the first ring is 6m, and the angle between the inclined part 12 and the main body 11 in the dust suppression equipment in the second ring is 1.3 times the angle between the inclined part 12 and the main body 11 in the dust suppression equipment in the first ring.

[0055] S3. Install a third layer of dust suppression equipment around the second layer of dust suppression equipment.

[0056] The distance between the dust suppression equipment in the third ring and the dust suppression equipment in the second ring is 6m, and the angle between the inclined part 12 and the main body 11 in the dust suppression equipment in the third ring is 1.3 times the angle between the inclined part 12 and the main body 11 in the dust suppression equipment in the second ring.

[0057] S4. Connect the dust suppression equipment to the water source.

[0058] The implementation principle of a dust suppression method for building demolition is as follows: Setting up three concentric rings of dust suppression equipment creates three water curtains around the building, resulting in better dust suppression during the demolition process. Simultaneously, during the demolition, after the building collapses, dust spreads outwards along the ground and also gradually rises. By gradually increasing the spray angle of the dust suppression equipment from the inside out, it can match the dust's diffusion trajectory, thus improving the dust suppression effect.
