[0058] This embodiment provides a dust suppression device for intelligent building construction, including:

[0059] The support platform 1 includes a lower bracket and a closing plate arranged on the outside of the lower bracket, and the interior of the support platform 1 is hollow and forms a placement chamber;

[0060] Dust reduction components, several dust reduction components are evenly distributed on the upper side of the support platform 1;

[0063] Dust suppression cylinder, the dust suppression cylinder is arranged on the adjustment frame 2.

[0064] In this technical solution, during construction, a corresponding number of dust suppression devices are deployed based on the area of the construction site. A towing hook is provided at one end of the support platform 1, enabling the dust suppression device to be towed by a vehicle for adjustment. The adjustment frame within the dust suppression assembly adjusts the orientation and angle of the dust suppression barrel. When dust is heavy, multiple dust suppression assemblies are activated to remove dust from multiple angles and ranges, thereby improving dust suppression efficiency. When dust is light, only one dust suppression assembly is activated, saving energy and water. A water pipe is connected to the dust suppression assembly to supply water.

[0065] Example 2:

[0066] This embodiment provides an intelligent dust reduction device for building construction, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0067] The dust suppression cylinder includes:

[0068] The exhaust duct 3 is connected to the adjustment frame 2, and the exhaust duct 3 is wide at the bottom and narrow at the top, and the upper end is tapered;

[0069] A fixing frame is arranged at the lower end of the exhaust duct 3;

[0070] An exhaust motor 4 is provided on a side of the fixing frame away from the exhaust duct 3;

[0071] Exhaust fan blades, which are driven by exhaust motor 4, are provided on one side of the fixed frame close to the exhaust tube 3;

[0072] The end spray plate is arranged on the upper side of the exhaust cylinder 3, and the end spray plate is provided with a spray head.

[0073] In this technical solution, the two ends of the exhaust duct 3 are connected, and the exhaust fan blades are driven by the exhaust motor 4 to exhaust air to the other end of the exhaust duct 3, thereby blowing out the water mist sprayed by the spray head on the end spray disk, thereby achieving a good dust reduction effect; and the exhaust motor 4 can be controlled by a frequency converter, so that it can output exhaust with different output power according to different dust conditions, thereby achieving better energy-saving effects.

[0074] Example 3:

[0075] This embodiment provides an intelligent dust reduction device for building construction, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0076] The end spray plate includes:

[0077] The support plate 5 is fixedly arranged on the upper side of the exhaust tube 3;

[0078] An upper drive disk 6 is provided at the upper end of the support disk 5 and is freely rotatable;

[0079] Support frame 7, a ring-shaped support frame 7 is mounted on the upper side of the support plate 5;

[0080] Several sprinkler heads are evenly distributed on the upper support frame 7 according to the circumference, and the upper drive plate 6 rotates to drive the sprinkler heads to adjust the flow rate and water pressure;

[0081] The support plate 5 is annular, coaxially arranged with the exhaust duct 3 and fixedly connected; the upper drive plate 6 is rotatably connected to the support plate 5 through a large-diameter thin-walled bearing, and the upper drive plate 6 is provided with a number of evenly distributed tooth grooves; a drive frame is provided on the outside of the support plate 5, and a drive motor is provided on the drive frame to drive the upper drive plate 6 to rotate; the support frame 7 is fixedly arranged on the side of the support plate 5 away from the exhaust duct 3, and the end of the sprinkler head is connected to the water supply pipe, which extends from the outside of the support plate 5.

The upper drive plate 6 is provided with an annular groove, and a stopper is installed on the support plate 5 to insert into the annular groove. The stopper cooperates with the upper drive plate 6 to limit the maximum rotation angle. The rotation of the upper drive plate 6 drives the spray head on the support frame 7 to adjust the flow rate, flow rate, and water pressure, thereby achieving different spray flow rates and pressures in different situations, thereby improving the spraying effect and efficiency. The annular shape of the support plate 5 ensures that the spray head can better surround the upper end of the exhaust duct 3, ensuring uniform spray, while also not obstructing the airflow generated by the exhaust fan blades. The drive motor can drive the upper drive plate 6 to rotate forward or reverse, thereby adjusting the spray head. The water supply pipe connected to the end of the spray head can be equipped with an electrically controlled valve. The dust suppression equipment activates different numbers of electrically controlled valves according to the severity of the dust to supply water to the corresponding spray head, thereby effectively saving water. The spray heads connected to the activated solenoid valves are evenly distributed around the circumference, ensuring uniform spraying.

[0083] Example 4:

[0084] This embodiment provides an intelligent dust reduction device for building construction, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0085] Sprinklers include:

[0086] The nozzle 8 is in the shape of a cone with one end closed, and a plurality of evenly distributed dispersion holes are provided on the closed end of the nozzle 8;

[0087] An upper shell 9, wherein an upper flange 10 is formed on one side of the upper shell 9 and a connection port for connecting the nozzle 8 is formed on the other side;

[0088] The lower shell 11 is arranged on one side of the upper flange 10, and the lower shell 11 is provided with a lower flange 12 arranged opposite to the upper flange 10;

[0089] The middle adjustment component is arranged between the upper flange 10 and the lower flange 12 and cooperates with the upper drive plate 6.

[0090] In this technical solution, the nozzle 8 is conical and cooperates with the dispersion hole to better ensure the formation of water mist; the upper shell 9 can facilitate the connection of the nozzle, and a connecting pipe is formed at the end of the lower shell 11, which is connected to the water supply pipe; and the sprinkler head can be connected to the support frame 7 through an adjustable angle hinge, so that the angle of the sprinkler head can be adjusted; and the central adjustment member can adjust the aperture of the water through the cooperation of the upper drive disk 6, and then adjust the flow rate and water pressure, so as to better ensure the spraying effect.

[0091] Example 5:

[0092] This embodiment provides an intelligent dust reduction device for building construction, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0093] The center adjustment assembly includes:

[0094] The middle adjustment disk is placed between the upper shell 9 and the lower shell 11;

[0095] Inner adjustment blocks, wherein the plurality of inner adjustment blocks are evenly distributed along the circumference and adjacent inner adjustment blocks are in contact with each other, and flow channel holes are formed in the middle of the inner adjustment blocks distributed along the circumference;

[0096] A transmission connecting rod 13 is connected between the middle adjustment disk and the inner adjustment block;

[0097] The upper shell 9 and the lower shell 11 are both formed with guide grooves 16 for guiding the inner adjustment block.

[0098] In this technical solution, the middle adjustment disk can play a supporting role between the upper shell 9 and the lower shell 11, and at the same time can have a good sealing effect on the outer edge; and the number of the inner adjustment blocks can be four, six or eight; Figure 14 When the number shown is four, the shape of the positive projection of the inner adjustment block is a rectangle and the flow channel holes formed on the inner sides of the four inner adjustment blocks are square; Figure 12When the number shown in 13 is six or eight, the shape of the positive projection of the inner adjustment block is an isosceles trapezoid, and the flow channel holes formed on the inner sides of the six or eight inner adjustment blocks are regular hexagons or regular octagons. Furthermore, when the inner adjustment block moves along the guide slot 16, the shape of the flow channel holes remains unchanged and scales proportionally. The transmission connecting rod 13 cooperates with the rotation of the central adjustment disk, thereby converting the rotational motion into an oblique motion of the inner adjustment block along the guide slot 16. The central adjustment disk is driven by the upper drive disk 6, thereby controlling the forward or reverse rotation of the upper drive disk 6 to achieve scaling of the flow channel holes. Furthermore, when the flow rate and pressure of the water delivered to the sprinkler head are fixed, the flow rate, flow rate, and water pressure are adjusted by changing the cross-sectional area of the flow channel holes to better achieve the effect of spraying and reducing dust. Water first passes through the lower shell 11, then through the flow channel holes in the middle of the inner adjustment block, and then enters the upper shell 9.

[0099] Example 6:

[0100] This embodiment provides an intelligent dust reduction device for building construction, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0101] The internal adjustment block includes:

[0102] The upper adjusting portion 14 is quadrilateral and has an upper guide block formed on the upper adjusting portion 14 to cooperate with the guide groove 16 on the upper shell 9;

[0103] The lower adjusting portion 15 is quadrilateral and has the same cross-section as the upper adjusting portion 14 , and is provided with a lower guide block that cooperates with the guide groove 16 on the lower housing 11 ;

[0104] A support rod 17 is provided between the upper adjusting portion 14 and the lower adjusting portion 15 for supporting and connecting the upper adjusting portion 14 and the lower adjusting portion 15, and one end of the transmission rod is rotatably connected to the support rod 17;

[0105] An outer sealing component is provided on the edge between the upper adjusting portion 14 and the lower adjusting portion 15 .

[0106] In this technical solution, the outer sides of the upper and lower adjusting parts 14, 15 are coated with a sealing layer, and the outer side of the upper adjusting part 14 contacts the upper flange 10, while the outer side of the lower adjusting part 15 contacts the lower flange 12. The arrangement of the upper and lower adjusting parts 14, 15 ensures good sealing contact between the inner adjusting block and the upper and lower shells 9, 11. The support rod 17 provides a connection point for the transmission connecting rod 13, thereby facilitating the transmission of the middle adjusting disk. The arrangement of the external sealing assembly ensures the sealing effect between the upper and lower adjusting parts 14, 15, and ensures the sealing between adjacent inner adjusting blocks, thereby achieving good leak-proofing. The upper and lower adjusting parts 14, 15, and the support rod 17 can be fixed by welding or other means. In order to improve the strength of the connection between the upper adjusting part 14 and the lower adjusting part 15, reinforcing rods can be provided at both ends of the support rod 17 for connection; and the upper guide block and the lower guide block can be cylindrical; the inner adjusting block cooperates with the guide grooves 16 on the upper shell 9 and the lower shell 11 through the upper guide blocks and the lower guide blocks on both sides. When the middle adjusting disk rotates, the rotational force will be transmitted to the support rod 17 through the transmission connecting rod 13 and squeeze it. Since the inner adjusting block cannot rotate under the limitation of the guide groove 16 and the adjacent inner adjusting block, the inner adjusting block can only run along the direction of the guide groove 16, thereby realizing the proportional scaling of the flow channel hole.

[0107] Example 7:

[0108] This embodiment provides an intelligent dust reduction device for building construction, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0109] The middle adjustment plate includes:

[0110] The outer disc 18 is annular and rests between the upper shell 9 and the lower shell 11. The inner adjustment blocks are evenly distributed on the inner side of the outer disc 18 along the circumference. The outer wall of the outer disc 18 is formed with external teeth that cooperate with the teeth of the upper drive disc 6. The external teeth are always engaged with the teeth during the limited angle adjustment of the sprinkler head.

[0111] Internal support blocks 19 are provided on the inner side of the outer disc 18 with a number of evenly distributed internal support blocks 19 equal to the number of internal adjustment blocks;

[0112] The outer support edge 20 is formed on both sides of the outer edge of the outer disc 18. A circular support groove is formed on the upper shell 9 and the lower shell 11 to rotate with the outer support edge 20.

[0113] A rolling wear-resistant assembly is provided between the outer support edge 20 and the support groove. The rolling wear-resistant assembly includes a sealing sheet provided on the side wall of the outer support edge 20 and a supporting ball provided between the outer support edge 20 and the bottom of the support groove.

[0114] One end of the transmission connecting rod 13 is rotationally engaged with the inner support block 19 , and the other end is rotationally engaged with the support rod 17 on the inner adjustment block.

[0115] In this technical solution, the thickness of the outer disc 18 is greater than or equal to the thickness of the inner adjustment block body, thereby preventing water from entering the space between the inner adjustment block and the outer disc 18. The central adjustment disc supports and limits the inner adjustment block through the outer disc 18. The inner support block 19 is used to cooperate with the transmission connecting rod 13 to better transmit torque, and the outer support edge 20 is provided to limit the outer disc 18, thereby preventing it from deflecting during rotation. The provision of a rolling wear-resistant assembly not only reduces friction but also ensures the sealing between the outer disc 18 and the upper shell 9 and lower shell 11. The upper shell 9 and lower shell 11 are connected by several fixing pins that pass through the inner side of the middle and outer discs 18. The inner side of the outer disc 18 is provided with a rotating arc block 27 with a rotation groove that rotates with the fixing pins. The provision of the rotating arc block 27 ensures smooth rotation of the outer disc 18 without affecting the connection strength between the upper shell 9 and lower shell 11.

[0123] In this technical solution, the adjustment groove 24 can facilitate the installation and fixation of the outer sealing assembly; after the outer sealing body 21 is fixed, the upper adjustment portion 14 and the lower adjustment portion 15 are extended, thereby improving the sealing of the cross-section between adjacent inner adjustment blocks; and the setting of the deformation groove 22 can better deform when the outer sealing body 21 is squeezed, thereby ensuring the sealing of the contact between the outer sealing body 21 and the outer sealing assembly on the adjacent inner adjustment block, and ensuring the sealing between the upper adjustment portion 14 and the lower adjustment portion 15. The inner sealing body 23 provided can support the outer sealing body 21 on the inner side of the outer sealing body 21 and prevent the outer sealing body 21 from shifting, thereby better playing the role of sealing and leak prevention. The outer sealing assembly can be set along the contour of the inner adjustment block, or it can be set on the inner side of the position corresponding to the two edges that can contact two adjacent inner adjustment blocks.

[0130] In this technical solution, the inner support sheet 25 is made of elastic metal and has an interference fit with the deformation groove 22, thereby supporting the outer seal body 21 and ensuring the overall structural stability of the outer seal body 21. At the same time, it ensures a good sealing effect of the outer seal body 21 when the outer sealing components in the adjacent inner adjustment blocks are squeezed and contacted. The provision of the outer extension body 26 can extend the contact range of the outer seal body 21, thereby achieving a good sealing and leak-proof effect even when there are installation errors. In addition, the outer seal body 21 and the extension body made of flexible material can provide a certain extrusion gap for the displacement of the inner adjustment block when squeezed, thereby preventing the inner adjustment block from being obstructed during displacement.
