Abstract

This invention belongs to the field of air pollution control technology, specifically relating to a high-efficiency dust suppression device for green building construction. It includes a control console and a bracket rotatably mounted on the console. A blower is rotatably mounted on the bracket and bolted to a conical barrel. A spraying assembly is installed at the end of the conical barrel, and an adjustment assembly is installed on the conical barrel. An annular pipe is installed inside the conical barrel and connected to a high-pressure pump. The spraying assembly includes a nozzle and a hose.

Description

Technical Field

[0001] This invention belongs to the field of air pollution control technology, and specifically relates to a high-efficiency dust suppression device for green building construction. Background Technology

[0002] With the continuous acceleration of urban modernization, a large number of construction sites have inevitably emerged in cities. Due to earthwork excavation, cement spillage from concrete mixing plants, and exposed ground surfaces, construction sites often generate significant dust. According to the provisions of GB / T50905-2014 standard on environmental protection of construction sites, in order to avoid affecting the surrounding environment and protect the health of workers, various means need to be adopted to control dust. Construction sites should have effective dust reduction measures.

[0003] For construction projects, existing technologies mostly employ spraying and water-sprinkling methods to suppress dust. Water is pressurized by a high-pressure pump and then atomized into tiny particles through specialized nozzles, or sprayed using high-pressure water sprinklers. These water droplets collide with and agglomerate dust particles in a designated area, forming larger particles that then settle, thus achieving dust suppression.

[0004] Existing dust suppression devices used in construction are easily affected by wind. In windy weather, water droplets are easily dispersed and fail to reach the intended dust-generating area, thus reducing the dust suppression effect. Because strong winds alter the spray trajectory, forcing it to change from a straight line to an arc, the actual spraying distance is reduced. Even with timely adjustments to the nozzle direction, the sprayed water droplets may still fail to reach the intended dust-generating area, for example, [the following text is incomplete and likely refers to an error in the original source]. Figure 11 As shown. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a high-efficiency dust suppression device for green building construction, thereby solving the technical problems in the prior art.

[0006] The objective of this invention can be achieved through the following technical solution: A high-efficiency dust suppression device for green building construction, comprising a control console and a bracket rotatably mounted on the control console. A blower is rotatably mounted on the bracket and bolted to a conical barrel. A spraying assembly is mounted at the end of the conical barrel, and an adjusting assembly is mounted on the conical barrel. An annular pipe is installed inside the conical barrel and connected to a high-pressure pump. The spraying assembly includes a nozzle and a hose. A hose is mounted on the annular pipe and movably connected to the nozzle. The adjusting assembly includes a movable rod. A fixed frame is mounted on the annular pipe, and the movable rod is movably connected to the fixed frame via a ball joint. One end of the movable rod is connected to a connector, and the other end is connected to a longitudinal air vane and a transverse air vane. A flexible annular plate is rotatably mounted on the annular pipe and fixedly connected to the nozzle. A push rod is fixedly mounted on the connector and fixedly connected to the flexible annular plate, and the push rod pushes the flexible annular plate to rotate. A sliding rod is slidably mounted inside the push rod, and one end of the sliding rod is connected to a pressure plate, which presses the hose.

[0007] As a further optimization or improvement of this solution, a cylinder is installed on the connector, the output end of the cylinder is connected to a push plate, the push plate is connected to a push block through a connecting rod, and the push block and the slide rod push each other to move.

[0008] As a further optimization or improvement of this solution, the spraying assembly also includes an inclined platform and a pressure platform. The inclined platform and the pressure platform are respectively installed on the inner wall of the conical barrel, and the inclined platform and the pressure platform are in contact with the nozzle and the hose respectively.

[0009] As a further optimization or improvement of this solution, the longitudinal air plate is longitudinally slidably connected to the conical barrel through a longitudinal plate, and the transverse air plate is laterally slidably connected to the conical barrel through a transverse plate.

[0010] As a further optimization or improvement of this solution, an adjustment head is installed on the movable rod, and the adjustment head slides in conjunction with the longitudinal groove on the horizontal plate and the transverse groove on the vertical plate.

[0011] As a further optimization or improvement of this solution, a hard block is provided on the flexible ring plate, the hard block abuts against the flexible hose, a sliding groove is opened in the hard block, the pressure plate slides in the sliding groove, and the push rod contacts the flexible ring plate.

[0012] As a further optimization or improvement to this solution, the control console has a built-in motor that drives the bracket to rotate, and the bracket drives the blower barrel and the conical barrel to rotate synchronously.

[0013] The beneficial effects of this invention are:

[0014] (1) The present invention uses strong wind to drive the longitudinal wind plate and the transverse wind plate to move. Under the action of the movable rod, the nozzle rotates in the opposite direction of the wind, so that the nozzle sprays liquid droplets in the wind. In this process, the strong wind drives the trajectory of the liquid droplet spraying to change, so that the liquid droplets are finally sprayed towards the dust area, reducing the influence of wind on the liquid droplet spraying position.

[0015] (2) When the nozzle in this invention rotates in the opposite direction of the wind, the hose near the wind end will be pressed by the hard block on the flexible ring plate, which increases the water pressure sprayed from the nozzle near the wind end, so that the sprayed liquid droplets have a certain wind-breaking effect, reducing the influence of the wind on the liquid droplet spray trajectory of the nozzle on the other side, and improving the stability of the liquid droplet spray trajectory.

[0016] (3) The present invention uses a cylinder to drive the push block to move and push the slide bar and pressure plate to move, so that the pressure plate presses all the hoses, increases the water pressure of all the nozzles, increases the travel of the spray trajectory, and enables the liquid droplets to be accurately sprayed in the dusty area.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 are within the scope of protection of the present invention.

[0032] See Figures 1-9 A high-efficiency dust suppression device for green building construction includes a control console 1 and a bracket 2 rotatably mounted on the control console 1. A blower 3 is rotatably mounted on the bracket 2 and bolted to a conical barrel 4. A spraying assembly 5 is installed at the end of the conical barrel 4, and an adjusting assembly 6 is installed on the conical barrel 4. An annular pipe 7 is installed inside the conical barrel 4 and connected to a high-pressure pump. The spraying assembly 5 includes a nozzle 501 and a hose 502. The hose 502 is installed on the annular pipe 7 and is movably connected to the nozzle 501. The adjusting assembly 6 includes a movable rod 603, and a fixed bracket 8 is installed on the annular pipe 7. 03 is movably connected to the fixed frame 8 via the ball head 605. One end of the movable rod 603 is connected to the connector 604, and the other end of the movable rod 603 is connected to the longitudinal air plate 601 and the transverse air plate 602. A flexible ring plate 608 is rotatably installed on the annular pipe 7. The flexible ring plate 608 is fixedly connected to the nozzle 501. A push rod 606 is fixedly installed on the connector 604. The push rod 606 is fixedly connected to the flexible ring plate 608, and the push rod 606 pushes the flexible ring plate 608 to rotate. A slide rod 612 is slidably installed inside the push rod 606. One end of the slide rod 612 is connected to the pressure plate 613, and the pressure plate 613 presses the hose 502.

[0033] Specifically, a cylinder 607 is installed on the connector 604, and the output end of the cylinder 607 is connected to a push plate 609. The push plate 609 is connected to a push block 611 through a connecting rod 610, and the push block 611 and the slide rod 612 push and move.

[0034] Specifically, the spraying assembly 5 also includes a ramp 503 and a pressure plate 504. The ramp 503 and the pressure plate 504 are respectively installed on the inner wall of the conical barrel 4, and the ramp 503 and the pressure plate 504 are in contact with the nozzle 501 and the hose 502 respectively.

[0035] Specifically, the control console 1 has a built-in motor that drives the bracket 2 to rotate, and the bracket 2 drives the blower barrel 3 and the conical barrel 4 to rotate synchronously.

[0036] It should be noted that before using this invention, the pointing positions of the blower barrel 3 and the conical barrel 4 need to be adjusted by the built-in motor of the control console 1, and then the ejection angle of the blower barrel 3 and the conical barrel 4 needs to be adjusted by the bracket 2.

[0037] In the absence of wind, under the action of the high-pressure pump, the liquid inside the annular pipe 7 is ejected through the hose 502 and the nozzle 501, causing the liquid droplets to reach the dust-generating area 9 along the spray trajectory 10. (See below) Figure 10 As shown.

[0038] In windy conditions, strong winds affect the spray trajectory 10 of the liquid droplets, forcing it to change from a straight line to an arc. This causes the spray trajectory 10 to deviate from the dust-generating area 9, and simultaneously reduces the actual travel distance of the spray trajectory 10. (See [link]). Figure 11 As shown.

[0039] During this process, the strong wind blows the corresponding longitudinal wind vane 601 and transverse wind vane 602, causing the longitudinal wind vane 601 and transverse wind vane 602 to drive one end of the movable rod 603 to move with the wind direction. Under the action of the ball head 605 and the fixed frame 8, the other end of the movable rod 603 moves in the opposite direction of the wind direction. That is, the movable rod 603 drives the connector 604 and the push rod 606 to move synchronously, causing the push rod 606 to push the flexible ring plate 608 and the nozzle 501 on the flexible ring plate 608 to rotate in the opposite direction of the wind direction. See below. Figure 12 The nozzle 501 sprays liquid droplets into the wind. During this process, the strong wind causes the trajectory of the liquid droplet spraying trajectory 10 to change, so that the liquid droplets are finally sprayed toward the dust area 9.

[0040] Specifically, as the nozzle 501 rotates in the opposite direction of the wind, the hose 502 near the windward end is pressed by the hard block on the flexible ring plate 608, increasing the water pressure sprayed from the nozzle 501 near the windward end (e.g., Figure 12 The water pressure of the liquid droplet spray trajectory 10 on the right side of the middle is increased, so that the liquid droplets that are first affected by the wind have a certain wind-breaking effect, reducing the impact of strong wind on the remaining liquid droplet spray trajectory 10 and improving the stability of the liquid droplet spray trajectory 10.

[0041] Considering the trajectory changes of the spray trajectory 10, which reduce the actual travel of the spray trajectory 10 and cause the liquid droplets to fail to reach the dust area 9, this invention uses a cylinder 607 to drive a push plate 609 to move into the connector 604. The push plate 609 then pushes a push block 611 to move via a connecting rod 610. The movement of the push block 611 pushes a slide rod 612 and a pressure plate 613 to move, causing the pressure plate 613 to press down on the entire hose 502. This increases the water pressure of the entire nozzle 501, improves the travel of the spray trajectory 10, and allows the liquid droplets to be accurately sprayed onto the dust area 9.

[0042] For details, see Figure 3 and Figure 4 The ball head 605 divides the movable rod 603 into two ends. The end of the movable rod 603 connected to the connector 604 is the short lever arm, and the end of the movable rod 603 connected to the longitudinal wind vane 601 and the transverse wind vane 602 is the long lever arm. By arranging the long and short lever arms of the movable rod 603, and by using lightweight materials for the longitudinal wind vane 601 and the transverse wind vane 602, it is easier for strong winds to push the longitudinal wind vane 601 and the transverse wind vane 602, thereby improving the sensitivity of the adjustment component 6.

[0043] It should be noted that when the wind force reaches level 5, the equipment must be stopped immediately, as dust suppression equipment is not suitable in this environment.

[0044] See Figures 7-9 The longitudinal air plate 601 is longitudinally slidably engaged with the conical barrel 4 via the longitudinal plate 616, and the transverse air plate 602 is transversely slidably connected to the conical barrel 4 via the transverse plate 615.

[0045] Specifically, an adjustment head 614 is installed on the movable rod 603, and the adjustment head 614 slides in cooperation with the longitudinal groove 617 on the horizontal plate 615 and the transverse groove 618 on the vertical plate 616.

[0046] It should be noted that when strong winds blow the horizontal wind vane 602, see [the relevant documentation]. Figure 8 The horizontal air deflector 602 drives the adjusting head 614 to move laterally via the longitudinal slide groove 617 on the horizontal plate 615, while the longitudinal slide groove 617 provides longitudinal movement space for the adjusting head 614; when a strong wind blows the vertical air deflector 601, see... Figure 9 The longitudinal wind deflector 601 drives the adjusting head 614 to move longitudinally through the transverse sliding groove 618 on the longitudinal plate 616, while the longitudinal plate 616 reserves space for the adjusting head 614 to move laterally; the same applies when a strong wind blows the longitudinal wind deflector 601 and the transverse wind deflector 602 at the same time.

[0047] See Figures 3-6 The flexible ring plate 608 is provided with a hard block, which abuts against the flexible hose 502. A sliding groove is opened in the hard block, and the pressure plate 613 slides in the sliding groove. The push rod 606 is in contact with the flexible ring plate 608.

[0048] It should be noted that if the push rod 606 and the flexible ring plate 608 are not fixedly connected, during the process of the nozzle 501 rotating in the opposite direction of the wind, only the nozzle 501 near the windy end is pushed by the push rod 606 and the flexible ring plate 608 to turn, while the spraying direction of the nozzle 501 at the other end remains unchanged. Therefore, the spraying trajectory 10 of the nozzle 501 in the spraying direction is deflected by the wind force, while the spraying trajectory 10 of the rotating nozzle 501 is towards the dust area 9, thereby increasing the spraying range of the nozzle 501.

[0049] Working principle of the invention: Before using the invention, the pointing positions of the blower barrel 3 and the conical barrel 4 need to be adjusted by the built-in motor of the control console 1, and then the ejection angle of the blower barrel 3 and the conical barrel 4 needs to be adjusted by the bracket 2.

[0050] In the absence of wind, under the action of the high-pressure pump, the liquid inside the annular pipe 7 is ejected through the hose 502 and the nozzle 501, causing the liquid droplets to reach the dust-generating area 9 along the spray trajectory 10. (See below) Figure 10 As shown.

[0051] In windy conditions, strong winds affect the spray trajectory 10 of the liquid droplets, forcing it to change from a straight line to an arc. This causes the spray trajectory 10 to deviate from the dust-generating area 9, and simultaneously reduces the actual travel distance of the spray trajectory 10. (See [link]). Figure 11 As shown.

[0052] During this process, the strong wind blows the corresponding longitudinal wind vane 601 and transverse wind vane 602, causing the longitudinal wind vane 601 and transverse wind vane 602 to drive one end of the movable rod 603 to move synchronously with the wind direction. Under the action of the ball head 605 and the fixed frame 8, the other end of the movable rod 603 moves in the opposite direction of the wind. That is, the movable rod 603 drives the connector 604 and the push rod 606 to move synchronously, causing the push rod 606 to push the flexible ring plate 608 and the nozzle 501 on the flexible ring plate 608 to rotate in the opposite direction of the wind. See below. Figure 12 The nozzle 501 sprays liquid droplets into the wind. During this process, the strong wind causes the trajectory of the liquid droplet spraying trajectory 10 to change, so that the liquid droplets are finally sprayed toward the dust area 9.

[0053] Specifically, as the nozzle 501 rotates in the opposite direction of the wind, the hose 502 near the windward end is pressed by the hard block on the flexible ring plate 608, increasing the water pressure sprayed from the nozzle 501 near the windward end (e.g., Figure 12 The water pressure of the liquid droplet spray trajectory 10 on the right side of the middle is increased, so that the liquid droplets that are first affected by the wind have a certain wind-breaking effect, reducing the impact of strong wind on the remaining liquid droplet spray trajectory 10 and improving the stability of the liquid droplet spray trajectory 10.

[0054] Considering the trajectory changes of the spray trajectory 10, which reduce the actual travel of the spray trajectory 10 and cause the liquid droplets to fail to reach the dust area 9, this invention uses a cylinder 607 to drive a push plate 609 to move into the connector 604. The push plate 609 then pushes a push block 611 to move via a connecting rod 610. The movement of the push block 611 pushes a slide rod 612 and a pressure plate 613 to move, causing the pressure plate 613 to press down on the entire hose 502. This increases the water pressure of the entire nozzle 501, improves the travel of the spray trajectory 10, and allows the liquid droplets to be accurately sprayed onto the dust area 9.

[0055] For details, see Figure 3 and Figure 4 The ball head 605 divides the movable rod 603 into two ends. The end of the movable rod 603 connected to the connector 604 is the short lever arm, and the end of the movable rod 603 connected to the longitudinal wind vane 601 and the transverse wind vane 602 is the long lever arm. By arranging the long and short lever arms of the movable rod 603, and by using lightweight materials for the longitudinal wind vane 601 and the transverse wind vane 602, it is easier for strong winds to push the longitudinal wind vane 601 and the transverse wind vane 602, thereby improving the sensitivity of the adjustment component 6.
