Description

Technical Field

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

[0002] Spray dust suppression refers to the technology of suppressing and capturing dust by dispersing water into droplets and spraying them at dust sources. The principle is that the extremely fine particles produced by the spray have basically zero surface tension. When sprayed into the air, they can quickly absorb dust particles of various sizes in the air, forming effective dust control. This method has a good effect on dust control and reduction in large open areas, especially in construction areas.

[0003] The existing patent CN215138158U discloses a lifting dust suppression spray device for construction, including a fixed frame, a lifting mechanism and a spray mechanism, wherein the fixed frame is arranged on the ground, the lifting mechanism is arranged on the fixed frame, and the lifting mechanism and the fixed frame are fixedly connected, and the spray mechanism is arranged at the lower end of the lifting mechanism, and the spray mechanism is fixedly connected to the lifting mechanism. Although this structure can achieve the effect of dust suppression, due to the large amount of dust at the construction site, the dust suppression equipment is exposed to a harsh environment for a long time, and there is no protective measure for the dust suppression nozzle, dust is easily accumulated on the nozzle when idle, and even dust enters the nozzle to cause blockage, shortening its service life and increasing maintenance costs. Summary of the invention

[0004] In view of the deficiencies in the prior art, an object of the present invention is to provide a dust suppression device for construction, which can effectively protect the nozzle when idle, avoid long-term exposure to harsh environments, and extend the service life of the nozzle.

[0005] The technical solution adopted by the present invention to solve its technical problem is: A dust suppression device for construction includes a fixed seat, a support rod and a spray mechanism. The lower end of the support rod is connected to the fixed seat and also includes a protective cover. The support rod is a hollow structure. The spray mechanism is placed inside the support rod. A lifting unit is provided at the bottom of the spray mechanism. The protective cover is placed at the top port of the support rod, and the protective cover is hinged to the support rod.

[0006] Compared with the prior art, the present invention has the following beneficial effects: The present invention adds a protective cover on the top of the support rod. When the lifting unit pushes the spray mechanism to rise, the spray mechanism pushes open the protective cover, and the protective cover does not affect the spraying work. When the dust reduction is over, the protective cover is closed in time, which can effectively protect the atomizing nozzle inside the support rod from being damaged, reduce the accumulation of dust on the surface of the nozzle, keep the nozzle clean, ensure the stability of the spray effect, extend the service life of the atomizing nozzle, and reduce the frequency and cost of equipment maintenance.

[0007] Further, the preferred embodiment adopted by the present invention is: An external connection plate is arranged on the outer wall of the top end of the support rod, and the protective cover is connected to the external connection plate through a spring hinge.

[0008] A baffle is arranged at one end of the external connecting plate away from the supporting rod.

[0009] The spray mechanism includes a lifting cylinder and an atomizing nozzle. The lifting cylinder is slidably connected to the inner wall of the support rod. The atomizing nozzle is placed on the top of the lifting cylinder. The lifting cylinder is connected to the atomizing nozzle through a water delivery pipe arranged inside the lifting cylinder. The water delivery pipe is connected to an external water supply device through a hose.

[0010] It also includes a connecting branch head, the water inlet end of the connecting branch head is connected to the top of the water delivery pipe, and each water outlet end of the connecting branch head is connected to the atomizing nozzle one by one.

[0011] An arc-shaped round cover is arranged on the top of the lifting cylinder. The arc-shaped round cover is provided with mounting holes corresponding to the position of each atomizing nozzle, and the atomizing nozzle is placed in the mounting holes.

[0012] The lifting unit is an electric push rod, which is connected to the bottom of the lifting cylinder.

[0013] The inner wall of the support rod is symmetrically provided with a limit guide rail, and the outer wall of the lifting cylinder is symmetrically provided with a limit slide plate, and the limit slide plate is slidably matched with the limit guide rail. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention is further described below in conjunction with specific embodiments, the purpose of which is only to provide a better understanding of the content of the present invention. Therefore, the examples given do not limit the protection scope of the present invention.

[0016] like Figure 1 , Figure 2 As shown, a dust suppression device for construction is composed of a fixed base 2, a support rod 1, a spray mechanism 6 and a protective cover 3. The support rod 1 is an internal hollow structure, and the lower end of the support rod 1 is connected to the fixed base 2. The lower end of the support rod 1 is circumferentially evenly provided with a plurality of reinforcing ribs 4 around its outer edge, and the support rod 1 is reinforced and fixed to the fixed base 2 by the reinforcing ribs 4; a plurality of bolt holes are circumferentially arranged on the fixed base 2, and the fixed base 2 is connected to the ground or other fixed equipment by a bolt assembly placed in the bolt hole to fix the dust suppression device as a whole.

[0017] like Figures 1 to 3 As shown, an external plate 12 is fixedly connected to the outer wall at the top of the support rod 1, and a protective cover 3 is installed at the end of the external plate 12 away from the support rod 1 through a spring hinge 7. The protective cover 3 can rebound through the spring hinge 7 to ensure that when the spray mechanism 6 does not lift up the protective cover 3, the protective cover 3 can cover the top of the support rod 1 to protect the spray mechanism 6.

[0018] In this embodiment, a baffle 5 is fixedly connected to the end of the external plate 12 away from the support rod 1. The baffle 5 is placed on the outside of the spring hinge 7. The baffle 5 can block the protective cover 3 to prevent the protective cover 3 from being folded or damaged by external forces such as strong winds.

[0019] like Figure 3 , Figure 4 As shown, the spray mechanism 6 is placed inside the support rod 1, and a lifting unit is provided at the bottom of the spray mechanism 6. The specific structure is: the spray mechanism 6 consists of a lifting cylinder 61, an atomizing nozzle 66 and a connecting branch head 65. The bottom of the lifting cylinder 61 is threadedly connected with a bottom plug 62, and a water delivery pipe 63 is installed inside the lifting cylinder 61. The bottom of the water delivery pipe 63 is close to the top of the bottom plug 62. A water pipe connector 64 is provided on the side wall of the water delivery pipe 63 close to the bottom, and the water pipe connector 64 passes through the side wall of the lifting cylinder 61; the water pipe connector 64 is connected to an external water supply device through a hose 69. In this embodiment, the hose 69 connection facilitates the up and down movement of the lifting cylinder 61.

[0020] The top of the water delivery pipe 63 is threadedly connected to the water inlet end of the connecting branch head 65; the connecting branch head 65 is provided with a plurality of water outlet ends, each of which is respectively connected to an atomizing nozzle 66.

[0021] In this embodiment, in order to enable the spray mechanism 6 to better push open the protective cover 3 when it rises, a support plate 67 is fixedly connected to the top port of the lifting cylinder 61, and an arc-shaped round cover 68 is fixedly connected to the support plate 67. The outer diameter of the arc-shaped round cover 68 is larger than the inner diameter of the lifting cylinder 61, so that the arc-shaped round cover 68 can cover the top of the lifting cylinder 61; the arc-shaped round cover 68 has mounting holes corresponding to the position of each atomizing nozzle 66, and each atomizing nozzle 66 is placed in the mounting hole. The design of the arc-shaped round cover 68 is convenient for lifting the protective cover 3 and also effectively protects the atomizing nozzle 66.

[0022] The inner wall of the support rod 1 is symmetrically provided with a limit rail 10 , and the outer wall of the lifting cylinder 61 is symmetrically provided with a limit slide 9 adapted to the limit rail 10 . The lifting cylinder 61 is slidably connected to the support rod 1 through the cooperation of the limit slide 9 and the limit rail 10 .

[0023] The lifting unit in this embodiment is an electric push rod 8, the telescopic end of the electric push rod 8 is connected and fixed to the bottom plug 62 at the bottom of the lifting cylinder 61, and the controller 11 of the electric push rod 8 is installed on the outer wall of the support rod 1, and the electric push rod 8 is electrically connected to its controller 11. By controlling the extension of the electric push rod 8, the telescopic end of the electric push rod 8 pushes the bottom plug 62 to move upward, and the movement of the bottom plug 62 drives the lifting cylinder 61 to move upward.

[0024] When the above structure is used, S1, firstly, a water pipeline is laid on the ground of the construction site, and then the fixing base 2 is fixed to the ground through which the water pipeline passes; S2. Connect the water pipeline to the water delivery pipe 63 through the hose 69; when dust reduction is required during construction, the construction personnel control the electric push rod 8 to extend, and the telescopic end of the electric push rod 8 pushes the bottom plug 62 to move upward, and the movement of the bottom plug 62 drives the lifting cylinder 61 to move upward, and the lifting cylinder 61 drives the limiting slide plate 9 to move upward along the limiting guide rail 10. At the same time, the arc-shaped round cover 68 on the top of the lifting cylinder 61 lifts up the protective cover 3 during the upward movement of the lifting cylinder 61, and the protective cover 3 rotates to the side of the baffle 5. At this time, the top of the support rod 1 is opened, and when the arc-shaped round cover 68 moves to the top of the protective cover 3, the protective cover 3 is tightly attached to the outer side of the limiting slide plate 9 under the action of the spring hinge 7; S3, the construction personnel open the water supply valve, the water flows through the water pipeline to the hose 69, and then through the hose 69 to the inside of the water delivery pipe 63, and then through the connecting branch head 65 to each atomizing nozzle 66 for atomization and spraying; S4. When the construction is completed and dust suppression is no longer needed, the construction personnel control the electric push rod 8 to retract, and the telescopic end of the electric push rod 8 drives the bottom plug 62 to move downward, and the movement of the bottom plug 62 drives the lifting cylinder 61 to move downward, thereby driving the arc-shaped round cover 68 to move downward. When the top end of the arc-shaped round cover 68 moves to the inside of the support rod 1, the protective cover 3 covers the top end of the support under the action of the spring hinge 7 to protect the atomizing nozzle 66.

[0025] The present invention provides a protective cover at the top of the support rod that cooperates with the spray mechanism to rise and fall, thereby effectively protecting the atomizing nozzle inside the support rod from damage and reducing dust accumulation on the surface of the atomizing nozzle to a certain extent, maintaining the cleanliness of the atomizing nozzle, preventing the atomizing nozzle from being clogged by dust when idle, extending the service life of the atomizing nozzle, and reducing the frequency and cost of equipment maintenance.

[0026] The above description is only the preferred embodiment of the present invention, and does not limit the scope of rights of the present invention. All equivalent changes made by using the contents of the present invention specification and its drawings are included in the scope of rights of the present invention.
