Technical Field

[0001] The invention relates to the technical field of construction dust reduction, in particular to a dust reduction device for environmental protection engineering construction. Background Art

[0002] Dust problems are common and difficult to completely avoid in construction sites, road construction, mining and other places. Construction workers who are exposed to high-concentration dust environments for a long time are prone to respiratory diseases such as pneumoconiosis. As society pays more attention to environmental protection, the requirements for dust control at construction sites in various places are becoming increasingly stringent. Construction units need to take effective measures to reduce dust emissions to meet environmental protection standards.

[0003] The environment at construction sites is complex and changeable, requiring both large-scale dust control and centralized dust treatment in local areas under specific circumstances. However, existing dust suppression equipment, such as water mist spraying equipment, can basically only provide a single spraying behavior. Traditional nozzles mostly spray at fixed angles, usually upward or horizontally, and cannot adjust the direction in real time according to construction dynamics or the needs of construction personnel. It is difficult to adjust the amount of dust or regional changes when vehicles pass by or other special construction behaviors, and the ability to respond to sudden dust is insufficient.

When the pedal mechanism is not triggered, the water curtain mechanism distributes a water source of the driving nozzle to the surface of the capturing screen to form a dust-absorbing water curtain. When the pedal mechanism is triggered, the water curtain mechanism automatically closes the capturing screen and guides the water source of the driving nozzle to flow out from the outside of the enclosure body, thereby flushing the dust adhered to the surface of the enclosure body.

The pitch angle of the water outlet is controlled by the pedal mechanism to realize the automatic switching of the dual modes of oblique upward diffusion dust reduction and oblique downward centralized isolation. When a scene with a large amount of dust is about to or has already occurred, the user can step on the pedal to trigger the moving inner plate and drive the water outlet to move downward, thereby isolating the water curtain in front of the user, avoiding the generation of huge amounts of dust and causing adverse effects on the breathing environment of construction workers, providing active protection, and directly absorbing and degrading the generated dust to avoid secondary dust.

[0014] 2. By setting up a water curtain mechanism, the water flow sprayed from the nozzle drives the nozzle to rotate to form a spraying water curtain, and the used water flow is distributed to the driving cylinder through the distributor, flows through the capture screen through the water trough, and forms a water curtain on the surface of the capture screen to capture dust.

DETAILED DESCRIPTION

[0018] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] The present invention will be further described below with reference to the embodiments. Example

[0020] This embodiment is a dust suppression device for environmental protection engineering construction, such as Figures 1-10 As shown, it includes an enclosure body 1, a movable inner plate 2 is slidably connected to the interior of the enclosure body 1, and a driving cylinder 3 is fixedly connected to the top of the movable inner plate 2. A water outlet 18 and a pedal mechanism are respectively provided at the upper and lower ends of the left side of the enclosure body 1. When the pedal mechanism is triggered, the spraying direction of the water outlet 18 is changed by the displacement of the movable inner plate 2. When the pedal mechanism is not triggered, the water outlet 18 diffuses and sprays obliquely upward. When the pedal mechanism is triggered, the water outlet 18 sprays obliquely downward and forms a dust-isolating protective water curtain. The pedaling mechanism includes a pedal 22, and a piston rod 25 is provided at the top of the pedal 22. The outer rod at the top of the piston rod 25 is fixedly connected to the left side of the enclosure body 1, and the inner rod at the bottom end of the piston rod 25 is fixedly connected to the top of the pedal 22. A torsion spring 26 is sleeved on the inner rod of the piston rod 25, and the top of the torsion spring 26 is fixedly connected to the outer rod of the piston rod 25. A gear 24 is engaged with the right side of the piston rod 25, and a tooth block 23 is evenly engaged with the bottom end of the left side of the movable inner plate 2. The tooth block 23 is engaged with the gear 24 and is triggered by human footsteps or other external forces.

[0021] The top end of the driving cylinder 3 is rotatably connected to the top block 4, and the top end of the top block 4 is connected to the nozzle 1 5. The nozzle 1 5 is driven by hydraulic power to rotate and spray water mist.

[0022] As a preferred implementation in this embodiment, Figure 3 and Figure 4 As shown, the bottom end of the top block 4 is connected to the delivery pipe 7, the bottom end of the delivery pipe 7 is evenly and fixedly connected to the water bucket 8, the bottom end of the driving cylinder 3 is fixedly connected to the nozzle 9, the bottom end of the delivery pipe 7 is connected to the access pipe 10, the bottom end of the access pipe 10 is slidably connected to the inner wall of the enclosure body 1, the access pipe 10 is connected to the delivery pipe 7 and the nozzle 9, the left and right ends of the top block 4 are fixedly connected to the second nozzle 6, after the top block 4 is moved out of the enclosure body 1, the second nozzle 6 synchronously receives the water flow transmitted by the delivery pipe 7 and performs horizontal rotation spraying.

[0023] The left end of the driving cylinder 3 is fixedly connected to a connecting frame 14, which is slidably connected to the enclosure body 1. A water outlet pipe 17 is fixedly connected to the surface of the connecting frame 14. Water holes 15 are evenly opened on one side of the water outlet pipe 17, and water holes 16 are evenly opened on the other side of the water outlet pipe 17. The distribution density and aperture of water holes 15 are higher than those of water holes 16. The bottom end of the water outlet 18 is sleeved on the surface of the water outlet pipe 17. The right end of the water outlet 18 is rotatably connected to a connecting rod 19. The bottom end of the connecting rod 19 is rotatably connected to a fixed rod 20. The right end of the fixed rod 20 is fixedly connected to the left side of the enclosure body 1. A water valve 27 is installed at the bottom end of the left side of the enclosure body 1. The water valve 27 is connected to the interior of the enclosure body 1. Compared with the existing technology, conventional devices require manual intervention to deal with sudden dust, such as the passing of a dump truck. The present device triggers the displacement of the mobile inner plate 2 through a pedal mechanism, thereby adjusting the angle of the water outlet 18 and synchronously adjusting the water flow distribution to achieve rapid response, forming an active dust barrier to provide protection for nearby people or objects.

[0024] In other aspects, this embodiment also provides a water curtain mechanism, such as Figure 7-10As shown, a water curtain mechanism is provided at the bottom end of the driving cylinder 3, and the water curtain mechanism includes a capture screen 21. When the pedal mechanism is not triggered, the water curtain mechanism distributes the water source used by the driving nozzle 5 to the surface of the capture screen 21 to form a dust-absorbing water curtain. When the pedal mechanism is triggered, the water curtain mechanism automatically closes the capture screen 21 and guides the water source used by the driving nozzle 5 to flow out from the outside of the enclosure body 1, so as to flush the dust adhered to the surface of the enclosure body 1.

[0025] The water curtain mechanism includes a water outlet 12, which is opened at the left end of the enclosure body 1, a water tank 13 is opened inside the movable inner plate 2, and a distributor 11 is fixedly connected to the left side of the bottom end of the driving cylinder 3. The water flow dispersion direction of the distributor 11 is staggered with the position of the water outlet 12, and the position of the water outlet 12 is higher than the water inlet of the water tank 13. Figure 4 As shown, when the position of the water outlet 12 is higher than the water inlet of the water trough 13, the water flowing out of the distributor 11 flows out through the water inlet of the water trough 13, and then flows out through the water trough 13 to form a water curtain later. Conversely, when the position of the water inlet of the water trough 13 is higher than the water outlet 12, the water flowing down through the distributor 11 directly flows out through the water outlet 12, and then flushes the outer surface of the enclosure body 1.

[0026] As a preferred implementation method in this embodiment, the number of capture screens 21 is six, and the six capture screens 21 are grouped in pairs and evenly fixed on the surface of the movable inner plate 2. Slots corresponding to the size of the capture screens 21 are provided on the left and right sides of the enclosure body 1. The slots of the enclosure body 1 serve as the entrance or exit for the capture screens 21 to contact external dust.

[0027] Compared with existing technologies, ordinary dust reduction equipment only focuses on airborne dust and ignores secondary pollution caused by dust accumulation in the equipment itself. This design solves the dual needs of air dust reduction and equipment surface cleaning by switching the state of the water curtain mechanism.

[0028] Working principle: When the present invention is implemented, the user can arrange and fix multiple links of the device, and connect them to the water source through the inlet pipe 10 and the outlet pipe 17 to supply clean water; Under normal conditions, the water inlet of the access pipe 10 is divided into two paths. One path is directly sprayed out through the nozzle 5 through the delivery pipe 7, and the other path directly enters the driving cylinder 3 through the nozzle 9. The water flow sprayed by the nozzle 9 drives the water bucket 8 to rotate through its spraying force. The water bucket 8 drives the top block 4 to rotate through the delivery pipe 7, and the top block 4 drives the nozzle 5 to rotate, so that the water flow sprayed by the nozzle 5 rotates, and the water flow sprayed by the nozzle 9 is dispersed and sprayed through the distributor 11, flows into the enclosure body 1, and then enters through the water inlet of the water tank 13 inside the enclosure body 1. Inside the water tank 13, it flows through the surface of the capture screen 21 to capture the passing dust, and the sewage containing dust flows into the bottom of the enclosure body 1. The user discharges the sewage by keeping the water valve 27 open. When a high dust event occurs, the user can step on the pedal 22, so that the pedal 22 drives the inner rod of the piston rod 25 to move in its outer rod, and drives the torsion spring 26 to stretch, and the pedal 22 drives the gear 24 to rotate, and the gear 24 drives the movable inner plate 2 to rise through the tooth block 23. At this time, the movable inner plate 2 drives the capture screen 21 to be staggered with the groove on the surface of the enclosure body 1, and the capture screen 21 is closed. When the movable inner plate 2 moves upward to the limit distance, the water inlet position above the water tank 13 is higher than the water outlet 12. In this state, the water flowing down through the distributor 11 will slowly flow out through the water outlet 12, flushing the outer surface of the enclosure body 1, and directly forming a large-flow water curtain, while capturing dust; like Figure 3 and Figure 4 As shown, during the upward movement of the movable inner plate 2, the driving cylinder 3 and the top block 4 are synchronously driven to rise, so that the second nozzle 6 is moved out of the enclosure body 1. At this time, the water source in the delivery pipe 7 can also be sprayed out through the second nozzle 6. Then, the second nozzle 6 rotates synchronously with the first nozzle 5 and sprays water mist over a wider range. When the water outlet 18 is in a normal state, the water source is connected through the water outlet pipe 17, so that the water flows through the water hole 15 and then sprays out through the water outlet 18. When the pedal mechanism is triggered, the driving cylinder 3 drives the connecting frame 14 to move, and the water outlet 18 rotates downward on the surface of the water outlet pipe 17. The fixed rod 20 restricts the movement trajectory of the water outlet 18. The connecting rod 19 swings along with the movement of the water outlet 18, so that the water outlet 18 closes the water hole 15. The water hole 2 16 becomes the water outlet of the water outlet 18, so that the water outlet 18 sprays a dense water flow, forming an isolating water curtain in front of the user, directly blocking dust; When the user stops stepping on the pedal 22, the torsion spring 26 rebounds to its original position, causing all related components to return to their original positions.

[0029] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
