Description

Technical Field

[0001] This invention belongs to the field of dust suppression spray, specifically relating to a dust suppression spray separation device for green building construction. Background Technology

[0002] Dust suppression spray devices separate solid particles in the air by spraying water. Wall-mounted dust suppression spray devices are commonly used dust suppression equipment on construction sites because they do not occupy ground construction space and are flexible in their placement.

[0003] Patent publication number CN215539430U relates to a dust suppression spray device for green building construction, including a clamping assembly. Multiple sets of the clamping assembly are connected to spraying components. Each clamping assembly consists of locking bolts, a clamping seat, a first adjusting rod, an adjusting shaft, a sleeve, a second adjusting rod, a connecting ear plate, an upper fixing sleeve, a lower fixing sleeve, a main mounting groove, and a secondary mounting groove. Multiple sets of locking bolts are provided on one side of the clamping seat. The upper end of the clamping seat is provided with a first adjusting rod, and the upper end of the first adjusting rod is connected to an adjusting shaft and a second adjusting rod. A sleeve is provided at the connection between the first and second adjusting rods. The end of the second adjusting rod away from the first adjusting rod is connected to a lower fixing sleeve. An upper fixing sleeve is provided at the upper end of the lower fixing sleeve. Connecting ear plates are provided at the edges of the lower and upper fixing sleeves. The lower and upper fixing sleeves have a main mounting groove and a secondary mounting groove inside.

[0004] In existing technologies, the clamping and spraying components are set up, and the clamping base and the construction project protective fence are clamped and connected and locked together by locking bolts. The installation is convenient and can be directly installed on the construction project protective fence. However, when the water is sprayed out, the reverse thrust will cause the spray head to slowly deflect, causing the spray to deviate from the dust area, resulting in a large area of ​​dust suppression dead zone in the construction area. At the same time, the existing spray pipes mostly use simple single-point fixation without auxiliary support. Under the action of its own weight, it cannot maintain a stable posture, which makes the spray pipe joints easy to loosen and leak water. In addition, when adjusting the angle of the spray pipe, the operator needs to climb to work, which makes the adjustment work more strenuous and easy to misoperate, causing the spray pipe to fall. Summary of the Invention

[0005] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a dust suppression spray device for green building construction, which can prevent the spray nozzle from slowly deflecting due to the reverse thrust generated when the water is sprayed, thus avoiding the spray from deviating from the dust-generating area.

[0006] A dust suppression spray device for green building construction according to an embodiment of the present invention includes a support base and an adjustment assembly. A support rod is fixedly installed on the top of the support base, and a support plate is slidably installed on the circumferential surface of the support rod. A support spring is provided between the support rod and the support plate. A spray pipe is provided between the support base and the support plate, and a spray head is provided on the circumferential surface of the spray pipe. The adjustment assembly includes an adjustment groove, a moving hole, a square hole, a pressing plate, a pressing roller, an elastic telescopic block, and an adjustment block. After the limit of the spray pipe is released, the spray pipe can be manually rotated to a suitable angle. The support plate is released, causing it to move downwards and reset under the elastic force of the support spring. The adjustment groove is located on the circumference of the spray pipe, the moving hole is located on the top of the support base, the square hole is located on the top of the support base, the pressing plate is fixedly installed on the bottom of the support plate, the pressing roller is rotatably installed on the bottom of the pressing plate, the elastic telescopic block is fixedly installed on the inner wall of the support base, and the adjustment block is fixedly installed on the free end of the elastic telescopic block. The adjustment block is used to limit the spray pipe, the pressing plate is used to limit the adjustment block, and the support plate is used to fix the spray pipe.

[0007] In some embodiments of the present invention, the inner wall of the support plate is provided with a rubber pad, which can increase the friction between the support plate and the spray pipe. The top of the adjusting block is set as an inclined surface, which can reduce the friction between the adjusting block and the pressing roller. The pressing roller is in contact with the adjusting block.

[0008] In some embodiments of the present invention, the adjusting block contacts the moving hole, the right side of the adjusting block abuts against the adjusting groove, the pressing plate contacts the square hole, the free end of the elastic telescopic block moves to the right and stores force, and at the same time the adjusting block moves to the right and contacts the adjusting groove and restores the limiting position of the spray pipe.

[0009] In some embodiments of the present invention, a load-bearing component and a control component are also included. The load-bearing component is used to assist in supporting the spray pipe, and the control component is used to prevent the spray pipe from falling. The load-bearing component includes a linkage hole, a rack plate, a gear, a rack bracket, a load-bearing plate, and a load-bearing frame. Moving the rack bracket upward will cause the load-bearing plate to move upward, and moving the load-bearing plate upward will cause the load-bearing frame to move upward. Moving the load-bearing frame upward will contact the spray pipe and restore the auxiliary support for the spray pipe. The linkage hole is opened at the top of the support base. The rack plate is fixedly installed at the bottom of the support plate. The gear is rotatably installed on the inner wall of the support base. The load-bearing plate is slidably installed on the inner wall of the support base. The rack bracket is fixedly installed at the top of the load-bearing plate, and the load-bearing frame is fixedly installed at the bottom of the load-bearing plate.

[0010] In some embodiments of the present invention, a spring is provided between the gear and the support base, the load-bearing frame abuts against the spray pipe, the rack plate meshes with the gear, the rack frame meshes with the gear, and the downward movement of the load-bearing plate will drive the load-bearing frame to move downward. The downward movement of the load-bearing frame will disengage from the spray pipe and release the auxiliary support for the spray pipe.

[0011] In some embodiments of the present invention, the control component includes a connecting plate, a hollow column, a solid column, a speed control plate, and a rectangular hole. The solid column moves slowly upward, causing the speed control plate to move slowly upward, which in turn causes the support plate to move slowly upward. The support plate moves slowly upward and disengages from the spray pipe. The connecting plate is fixedly installed on the left side of the support base. The hollow column is fixedly installed on the top of the connecting plate. The solid column is slidably installed on the inner wall of the hollow column. The speed control plate is fixedly installed on the top of the solid column. The rectangular hole is formed on the circumferential surface of the solid column.

[0012] In some embodiments of the present invention, the control assembly further includes a synchronization plate and an elastic telescopic plate. The synchronization plate is fixedly installed on the circumferential surface of the solid column. After the angle of the spray pipe is adjusted, the free end of the elastic telescopic plate is pushed to the left and disengages from the contact with the top of the support base. The elastic telescopic plate is fixedly installed on the top of the synchronization plate, and the free end of the elastic telescopic plate abuts against the left side of the support base.

[0013] In some embodiments of the present invention, the hollow column is provided with a damping protrusion inside, and the solid column is provided with a rubber ring on its circumferential surface. The rubber ring can increase the friction between the solid column and the hollow column. The speed control plate is fixedly connected to the support plate. The speed control plate is limited by the free end of the elastic telescopic plate so that the support plate can remain detached from the spray pipe without manual support.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This invention allows for rapid adjustment of the spray angle after the spray pipe is manually rotated to a suitable angle once the limiting position is released. This enables real-time adaptation to the location and diffusion range of construction dust, eliminating dust suppression blind spots and improving dust suppression efficiency, thereby ensuring continuous and stable dust suppression operations. When the adjusting block moves to the right, it contacts the adjusting groove and restores the limiting position of the spray pipe. The reliable limiting position of the adjusting block and the adjusting groove, combined with the support plate for fixation, can counteract the reverse thrust generated by the spray water, thereby preventing the spray head from slowly deflecting and further ensuring the stable and effective preset dust suppression coverage area.

[0015] In this invention, the upward movement of the load-bearing plate will cause the load-bearing frame to move upward. The upward movement of the load-bearing frame will contact the spray pipe and restore the auxiliary support for the spray pipe. After the angle adjustment is completed, the load-bearing frame will quickly reset and support the spray pipe again. This can provide stable auxiliary support and enhance the overall structural strength of the device, thereby preventing the spray dust suppression from being interrupted due to loosening and water leakage at the spray pipe interface.

[0016] In this invention, the load-bearing frame moves downward and disengages from the spray pipe, releasing its auxiliary support. During the adjustment of the spray pipe angle, the load-bearing frame can automatically detach from the spray pipe, which can reduce rotational friction and make angle adjustment easier and less strenuous, thereby avoiding adjustment jamming or component wear.

[0017] In this invention, the speed control plate moves slowly upward, causing the support plate to move slowly upward as well. The support plate moves slowly upward and disengages from the spray pipe. Friction damping is formed by the rubber ring and the damping ridge, allowing the support plate to rise slowly and smoothly. This prevents the support plate from disengaging from the spray pipe too quickly, which could cause the spray pipe to fall, thus improving the safety of the adjustment process.

[0018] This invention allows the speed control plate to be limited by the free end of the elastic telescopic plate, so that the support plate can remain detached from the spray pipe without manual support. After the support plate is raised to the correct position, the elastic telescopic plate can automatically limit the support base, keeping the support plate detached without manual support. This avoids the need for operators to hold the plate for a long time, and significantly reduces the intensity and safety risks of climbing and adjusting the position. Attached Figure Description

[0021] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0022] like Figure 1 - Figure 7 As shown, one embodiment of the present invention is: a dust suppression spray device for green building construction, including a support base 1 and an adjustment assembly. A support rod 2 is fixedly installed on the top of the support base 1, and a support plate 3 is slidably installed on the circumferential surface of the support rod 2. A support spring 4 is provided between the support rod 2 and the support plate 3. A spray pipe 5 is provided between the support base 1 and the support plate 3, and a spray head 6 is provided on the circumferential surface of the spray pipe 5. The adjustment assembly includes an adjustment groove 7, a moving hole 8, a square hole 9, a pressing plate 10, a pressing roller 11, an elastic telescopic block 12, and an adjustment block 13. The adjustment groove 7 is opened on the circumferential surface of the spray pipe 5, and the moving hole 8 is opened on the circumferential surface of the spray pipe 5. A square hole 9 is opened on the top of the support base 1. The pressing plate 10 is fixedly installed on the bottom of the support plate 3. The pressing roller 11 is rotatably installed on the bottom of the pressing plate 10. The elastic telescopic block 12 is fixedly installed on the inner wall of the support base 1. The adjusting block 13 is fixedly installed on the free end of the elastic telescopic block 12. The adjusting block 13 is used to limit the spray pipe 5. The pressing plate 10 is used to limit the adjusting block 13. The support plate 3 is used to fix the spray pipe 5. The spray angle can be quickly adjusted, which can adapt to the construction dust position and diffusion range in real time, eliminate dust suppression blind spots and improve dust suppression efficiency, thereby ensuring continuous and stable dust suppression operation.

[0023] The inner wall of the support plate 3 is provided with a rubber pad, which can increase the friction between the support plate 3 and the spray pipe 5. The top of the adjusting block 13 is set as an inclined surface, which can reduce the friction between the adjusting block 13 and the pressing roller 11. The pressing roller 11 contacts the adjusting block 13.

[0024] Adjusting block 13 contacts moving hole 8, right side of adjusting block 13 abuts against adjusting groove 7, pressing plate 10 contacts square hole 9, free end of elastic telescopic block 12 moves to the right and stores force, while adjusting block 13 moves to the right and contacts adjusting groove 7 and restores the limit on spray pipe 5, which can counteract the reverse thrust generated by spray water, thereby preventing spray head 6 from slowly deflecting, and further ensuring the stability and effectiveness of the preset dust suppression coverage area.

[0025] In this embodiment, when it is necessary to adjust the coverage of the spray pipe 5 and the spray head 6, the support plate 3 is manually pushed upward. The upward movement of the support plate 3 will compress the support spring 4. The support spring 4 will deform and store force under the compression of the support plate 3. At the same time, the upward movement of the support plate 3 will disengage from the spray pipe 5. The upward movement of the support plate 3 will also drive the pressing plate 10 to move upward. The upward movement of the pressing plate 10 will drive the pressing roller 11 to move upward. The upward movement of the pressing roller 11 will disengage from the inclined surface of the adjusting block 13. After the adjusting block 13 disengages from the pressing roller 11, the adjusting block 13 will move to the left and reset under the action of the elastic telescopic block 12. When the adjusting block 13 moves to the left to reset, it will disengage from the adjusting groove 7 and release the limit on the spray pipe 5. After the limit on the spray pipe 5 is released, manually rotate the spray pipe 5 to a suitable angle and release the support plate 3 so that the support plate 3 moves downward to reset under the elastic force of the support spring 4. The downward movement of the support plate 3 will contact the spray pipe 5 and fix the spray pipe 5. At the same time, the downward movement of the support plate 3 will drive the pressing plate 10 to move downward. The downward movement of the pressing plate 10 will drive the pressing roller 11 to move downward. The downward movement of the pressing roller 11 will contact the inclined surface of the adjusting block 13 and squeeze the adjusting block 13. The adjusting block 13 moves to the right under the squeezing of the pressing roller 11. When the adjusting block 13 moves to the right, it will cause the free end of the elastic telescopic block 12 to move to the right. The free end of the elastic telescopic block 12 moves to the right and stores force. At the same time, when the adjusting block 13 moves to the right, it will contact the adjusting groove 7 and restore the limiting position of the spray pipe 5. The spray pipe 5 is limited by the adjusting block 13, thereby preventing the reverse thrust generated when spraying water from causing the spray head 6 to slowly deflect and the preset coverage area to fail.

[0026] Please see Figure 1 - Figure 7Based on the above embodiments, another embodiment of the present invention further includes a load-bearing component and a control component. The load-bearing component is used to assist in supporting the spray pipe 5, and the control component is used to prevent the spray pipe 5 from falling. The load-bearing component includes a linkage hole 141, a rack plate 142, a gear 143, a rack frame 144, a load-bearing plate 145, and a load-bearing frame 146. The linkage hole 141 is opened at the top of the support base 1. The rack plate 142 is fixedly installed at the bottom of the support plate 3. The gear 143 is rotatably installed on the inner wall of the support base 1. The load-bearing plate 145 is slidably installed on the inner wall of the support base 1. The rack frame 144 is fixedly installed at the top of the load-bearing plate 145. The load-bearing frame 146 is fixedly installed at the bottom of the load-bearing plate 145. The load-bearing frame 146 quickly resets and re-supports the spray pipe 5, which can provide stable auxiliary support and enhance the overall structural strength of the device, thereby preventing the spray dust suppression from being interrupted due to loosening and leakage at the interface of the spray pipe 5.

[0027] A spring is provided between gear 143 and support base 1. The load-bearing frame 146 abuts against the spray pipe 5. The rack plate 142 meshes with gear 143. The rack frame 144 meshes with gear 143. When the load-bearing plate 145 moves downward, it will drive the load-bearing frame 146 to move downward. When the load-bearing frame 146 moves downward, it will disengage from the spray pipe 5 and release the auxiliary support for the spray pipe 5. During the angle adjustment of the spray pipe 5, the load-bearing frame 146 can automatically disengage from the spray pipe 5, which can reduce the rotational friction and make the angle adjustment easier and less strenuous, thereby avoiding adjustment jamming or component wear.

[0028] The control assembly includes a connecting plate 151, a hollow column 152, a solid column 153, a speed control plate 154, and a rectangular hole 155. The connecting plate 151 is fixedly installed on the left side of the support base 1, the hollow column 152 is fixedly installed on the top of the connecting plate 151, the solid column 153 is slidably installed on the inner wall of the hollow column 152, the speed control plate 154 is fixedly installed on the top of the solid column 153, and the rectangular hole 155 is opened on the circumferential surface of the solid column 153. Through the friction damping formed by the rubber ring and the damping protrusion, the support plate 3 rises slowly and steadily, which can prevent the support plate 3 from separating from the spray pipe 5 too quickly and causing the spray pipe 5 to fall, thereby improving the safety of the adjustment process.

[0029] The control assembly also includes a synchronization plate 156 and an elastic telescopic plate 157. The synchronization plate 156 is fixedly installed on the circumferential surface of the solid column 153. After the angle of the spray pipe 5 is adjusted, the free end of the elastic telescopic plate 157 is pushed to the left and disengages from the contact with the top of the support base 1. The elastic telescopic plate 157 is fixedly installed on the top of the synchronization plate 156, and the free end of the elastic telescopic plate 157 abuts against the left side of the support base 1.

[0030] The hollow column 152 has a damping ridge inside, and the solid column 153 has a rubber ring on its circumference. The rubber ring can increase the friction between the solid column 153 and the hollow column 152. The speed control plate 154 is fixedly connected to the support plate 3. The speed control plate 154 is limited by the free end of the elastic telescopic plate 157, so that the support plate 3 can remain detached from the spray pipe 5 without manual support. After the support plate 3 rises to the position, the elastic telescopic plate 157 can automatically limit the support base 1, so that the support plate 3 remains detached without manual support, thereby avoiding the operator from holding it for a long time and greatly reducing the intensity and safety risks of climbing and adjusting.

[0031] In this embodiment, when the support plate 3 moves upward, it will drive the rack plate 142 to move upward. The upward movement of the rack plate 142 will compress the gear 143. The gear 143 will rotate clockwise due to the compression of the rack plate 142. The clockwise rotation of the gear 143 will compress the spring. The spring will deform and store force due to the compression of the gear 143. At the same time, the clockwise rotation of the gear 143 will compress the rack frame 144. The rack frame 144 will move downward due to the compression of the gear 143. The downward movement of the rack frame 144 will drive the load-bearing plate 145 to move downward. The downward movement of the load-bearing plate 145 will drive the load-bearing frame 146 to move downward. The downward movement of the support frame 146 will disengage from the spray pipe 5 and release the auxiliary support for the spray pipe 5, thereby reducing the friction force when the spray pipe 5 is rotated and adjusted. When the support plate 3 moves downward, it will drive the rack plate 142 to move downward. The downward movement of the rack plate 142 will squeeze the gear 143. The gear 143, squeezed by the rack plate 142 and combined with the elastic force of the spring, will rotate counterclockwise. The counterclockwise rotation of the gear 143 will drive the rack frame 144 to move upward. The upward movement of the rack frame 144 will drive the support plate 145 to move upward. The upward movement of the support plate 145 will drive the support frame 146 to move upward. The upward movement of the support frame 146 will bring it into contact with the spray pipe 5 and restore the auxiliary support for the spray pipe 5.

[0032] The upward movement of the support plate 3 will cause the speed control plate 154 to move upward. The upward movement of the speed control plate 154 will cause the rubber ring to move upward. The upward movement of the rubber ring will continuously rub against the damping protrusion inside the hollow column 152. When the rubber ring moves upward, the friction with the damping protrusion will form damping, causing the solid column 153 to move upward slowly. The slow upward movement of the solid column 153 will cause the speed control plate 154 to move upward slowly. The slow upward movement of the speed control plate 154 will cause the support plate 3 to move upward slowly. The support plate 3 moves upward slowly and disengages from the spray pipe 5, thereby preventing the spray pipe 5 from disengaging from the support plate 3 too quickly and falling. At the same time, the slow upward movement of the solid column 153 will cause the synchronization plate 156 to move upward slowly. The synchronous plate 156 moves slowly upward, which drives the elastic telescopic plate 157 to move upward. The upward movement of the elastic telescopic plate 157 causes its free end to disengage from the support base 1. After the free end of the elastic telescopic plate 157 disengages from the support base 1, it moves to the right under its own elastic force. The rightward movement of the free end of the elastic telescopic plate 157 will contact the top of the support base 1 and limit the speed control plate 154. The speed control plate 154 is limited by the free end of the elastic telescopic plate 157, so that the support plate 3 can remain detached from the spray pipe 5 without manual support, thereby reducing the workload of the operator in adjusting the spray pipe 5. After the angle of the spray pipe 5 is adjusted, the free end of the elastic telescopic plate 157 is pushed to the left and disengages from the top of the support base 1. After the free end of the elastic telescopic plate 157 disengages from the top of the support base 1, the support plate 3 can move downward and reset under the elastic force of the support spring 4.
