Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a spraying device suitable for building construction. Background Art

[0002] With the continuous development of technology and the progress of society, the construction industry is well-known to people. However, due to continuous construction on construction sites, the site is often filled with flying dust, which not only obscures the vision of workers but also causes the dust to spread to the urban area and affect the traffic of citizens. Usually, spraying devices are equipped on construction sites to reduce this impact.

[0003] The existing spraying devices for building construction use a water pump to make multiple spray pipes installed on the protective net perform spraying work. However, such spraying devices can only perform spraying work at one height. The dust at high places will be blown to the urban area by the wind, and at the same time, it may also be caused by insufficient pressure that the spraying distance is not far enough and the spraying is uneven, thus resulting in a decline in the dust reduction effect. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art. The existing spraying devices for building construction use a water pump to make multiple spray pipes installed on the protective net perform spraying work. However, such spraying devices can only perform spraying work at one height. The dust at high places will be blown to the urban area by the wind, and at the same time, it may also be caused by insufficient pressure that the spraying distance is not far enough and the spraying is uneven, thus resulting in a decline in the dust reduction effect. Therefore, a spraying device suitable for building construction is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A spraying device suitable for building construction includes a water inlet pipe and a box body. The water inlet pipe is fixedly connected to the lower end of the box body.

[0007] A lifting component is installed on one side of the water inlet pipe. The lifting component includes a rotating shaft, a piston cylinder, a telescopic pipe, a lifting plate, a spray pipe, a push rod, a piston plate, and an airbag. One end of the rotating shaft is rotatably connected to the water inlet pipe, and a fan blade is annularly arranged on the outer surface of the rotating shaft. The other end of the rotating shaft is fixedly connected to a cam. The piston plate is slidably connected in the piston cylinder. One end of the airbag close to the piston plate is fixedly connected to the inner wall of the piston cylinder. The push rod is slidably connected to the end of the piston cylinder away from the piston plate. A straight spring is fixedly connected between one end of the push rod and the inner wall of the piston cylinder. The telescopic pipe is communicated with the upper end of the water inlet pipe, and the other end of the telescopic pipe is fixedly connected to the lifting plate. The lifting plate is slidably connected in the box body. One end of the spray pipe passes through the lifting plate and is communicated with the telescopic pipe. A plurality of atomizing nozzles are fixedly connected to the outer surface of the spray pipe.

[0008] Preferably, the lifting member further includes a placement groove, a pressing block, a pressing rod, a straight rod, and a first return spring. The placement groove is fixedly connected to the side wall of the piston cylinder. The pressing block is slidably connected to one side wall of the placement groove. The pressing rod is slidably connected in the placement groove. The first return spring is fixedly connected between the pressing rod and the inner wall of the placement groove. The straight rod is fixedly connected to the pressing rod.

[0009] Preferably, one end of the airbag is fixedly communicated with an exhaust pipe. A disc is provided on the inner wall of the exhaust pipe near the airbag end. An exhaust hole is opened on the disc.

[0010] Preferably, a moving block is slidably connected to one side of the exhaust pipe near the straight rod. A baffle is slidably connected to the side wall of the disc. A second return spring is fixedly connected between the baffle and the inner wall of the exhaust pipe.

[0012] Preferably, the piston cylinder is fixedly connected to the inner wall of the box body.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] 1. The rotation of the fan blade in the water inlet pipe drives the rotation of the rotating shaft, continuously inflates and expands the airbag, pushes the push rod to move upward, so that the push rod pushes the lifting plate to move upward through the slider, and then the water spraying cavity moves upward, achieving the function of adjusting the height, making the water spraying range larger and adapting to more working environments.

[0015] 2. When the airbag expands to the top of the piston cylinder, it will squeeze the pressing block to move. Through the pressing rod, straight rod, and moving block, the airbag deflates, and the gas passes through the exhaust pipe and the jet chamber, and the gas is ejected, so that the water of the water spraying pipe is sprayed farther and more evenly, making the dust reduction effect better.

One end of the rotating shaft 3 is rotatably connected to the water inlet pipe 1, and fan blades 12 are annularly arranged on the outer surface of the rotating shaft 3. The fan blades 12 are light in mass and small in volume. The other end of the rotating shaft 3 is fixedly connected with a cam 4. The piston plate 13 is slidably connected in the piston cylinder 5, and the piston plate 13 and the piston cylinder 5 are sealed. One end of the air bag 14 close to the piston plate 13 is fixedly connected to the inner wall of the piston cylinder 5. An air inlet valve is installed at one end of the air bag 14 close to the piston plate 13. The push rod 11 is slidably connected to the end of the piston cylinder 5 away from the piston plate 13. A straight spring 15 is fixedly connected between one end of the push rod 11 and the inner wall of the piston cylinder 5. The telescopic pipe 6 is communicated with the upper end of the water inlet pipe 1, and the other end of the telescopic pipe 6 is fixedly connected to the lifting plate 7. The working principle of the telescopic pipe 6 is the same as that of the corrugated pipe in the prior art and has telescopic properties. The lifting plate 7 is slidably connected in the box body 2, and the lifting plate 7 slides in the box body 2 through the sliders fixedly connected at both ends. One end of the water spraying pipe 8 passes through the lifting plate 7 and is communicated with the telescopic pipe 6. The shape of the water spraying pipe 8 is T-shaped, and a plurality of atomizing nozzles are fixedly connected to the outer surface of the water spraying pipe 8.

[0025] The lifting component further includes a placement groove 16, a pressing block 17, a pressing rod 18, a straight rod 19, and a first return spring 20. The placement groove 16 is fixedly connected to the side wall of the piston cylinder 5. The pressing block 17 is slidably connected to one side wall of the placement groove 16. One end of the pressing block 17 is semicircular. The pressing rod 18 is slidably connected within the placement groove 16. The pressing rod 18 is composed of two semi-circular blocks and a circular rod. The first return spring 20 is fixedly connected between the pressing rod 18 and the inner wall of the placement groove 16. The straight rod 19 is fixedly connected to the pressing rod 18. One end of the airbag 14 is fixedly communicated with an exhaust pipe 9. A disc 23 is provided on the inner wall of the exhaust pipe 9 near the airbag 14. A sealing treatment is performed between the disc 23 and the exhaust pipe 9. An exhaust hole is opened on the disc 23. A moving block 21 is slidably connected to one side of the exhaust pipe 9 near the straight rod 19. A baffle 22 is slidably connected to the side wall of the disc 23. The baffle 22 closely fits the exhaust hole. A second return spring 24 is fixedly connected between the baffle 22 and the inner wall of the exhaust pipe 9. The end of the exhaust pipe 9 away from the piston cylinder 5 is fixedly connected to a jet cavity 10. The jet cavity 10 is fixedly connected to the upper end of the box body 2. Air holes are opened on the outer surface of the jet cavity 10. A plurality of air holes are opened around the jet cavity 10 near the water spray pipe 8. The piston cylinder 5 is fixedly connected to the inner wall of the box body 2.

[0026] In the present utility model, during use, first, a large amount of water enters through the water inlet pipe 1. The water flow drives the fan blade 12 to rotate, thereby driving the rotating shaft 3 to rotate. At this time, the cam 4 rotates, and the cam 4 continuously pushes the piston plate 13 to inflate the airbag 14. The airbag 14 continuously expands within the piston cylinder 5. When it expands to a certain size, it pushes the push rod 11 to move upward slowly. The push rod 11 pushes the lifting plate 7 to move within the box body 2. The lifting plate 7 pulls the telescopic tube 6 to move upward. At this time, the water spray pipe 8 also moves upward accordingly, making the water spraying range of the water spray pipe 8 wider and capable of adapting to various working environments. When the airbag 14 expands to the position of the pressing block 17, the airbag 14 pushes the pressing block 17 to move vertically within the placement groove 16, and pushes the pressing rod 18 to move horizontally within the placement groove 16. At this time, the straight rod 19 connected to the pressing rod 18 starts to move horizontally, pushing the moving block 21 to press the baffle 22. At this time, the baffle 22 slides on the surface of the disc 23, and the exhaust hole opened on the disc 23 is exposed. The airbag 14 starts to deflate. Due to the relatively large friction force between the baffle 22 and the disc 23, the baffle 22 will be slowly reset by the pushing action of the second return spring 24 after the airbag 14 is deflated. At the same time, the pressing rod 18 and the pressing block 17 are reset by the pushing action of the first return spring 20. The gas in the airbag 14 is discharged through the exhaust pipe 9 and the jet cavity 10. The discharged gas makes the water sprayed by the water spray pipe 8 have a larger acting range and be sprayed more evenly.

[0027] In the present utility model, unless otherwise clearly specified and defined, terms such as "installation", "connection", "linkage", "fixation", etc. shall be understood in a broad sense.

[0028] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
