Description

Technical Field

[0001] The utility model belongs to the technical field of building engineering, and in particular relates to a dust reduction device for building engineering construction. Background Art

[0002] A large amount of dust will be generated during the construction of construction projects. Dust pollution will affect the normal life of surrounding residents. At the same time, dust pollution also causes great damage to the environment. In the existing construction process, the dust generated during the construction process is eliminated by using fencing and atomized water. The main principle is that the atomized water contacts the dust, making the dust heavier and falling. The problem with the prior art is that the atomized water of the existing atomizing nozzles is mostly fan-shaped, which will result in the area between two adjacent atomizing nozzles being unable to effectively reduce dust. Based on the above situation, it is necessary to design a dust reduction device for construction engineering to solve the above problem. Utility Model Content

[0003] In view of the above problems, the purpose of the present utility model is to provide a dust reduction device for construction engineering, so as to solve the problem that the dust between two adjacent atomizing nozzles of the existing dust reduction device mentioned in the above background technology cannot be effectively eliminated.

[0004] To achieve the above objectives, the utility model adopts the following technical solution: a dust reduction device for construction engineering, comprising a water pipe installed on an enclosure, and an atomizing nozzle rotatably and sealably connected to a plurality of output ends of the water pipe evenly spaced apart via a connecting pipe; a horizontally arranged mounting frame is fixedly connected to the enclosure, the atomizing nozzle is rotatably connected to the mounting frame, and a driving component is also provided on the mounting frame for driving the atomizing nozzle to swing back and forth along the axis of the connecting pipe.

[0005] The beneficial effects of the utility model are as follows: in the normal dust reduction process, the water of the water pipe on the enclosure is transported to the atomizing nozzle through the connecting pipe, and the atomizing nozzle sprays the water in the form of water mist, which makes the dust fall after contacting the dust. A single water pipe is provided with multiple output ends, thereby realizing the synchronous atomization of water by multiple linearly arranged atomizing nozzles. Since there is a certain distance between two adjacent atomizing nozzles and the atomized water is generally sprayed in a fan shape, the atomization between two adjacent atomizing nozzles is insufficient, resulting in poor dust treatment effect. By adding a driving component to drive the atomizing nozzle to swing, sufficient atomization can be achieved between adjacent atomizing nozzles, thereby increasing the dust reduction effect.

[0006] In order to enable the drive assembly to drive multiple atomizing nozzles to perform synchronous reciprocating swings:

[0007] As a further improvement of the above technical solution: the driving assembly includes a rack with connecting rods at both ends, a gear fixed to the outside of the atomizing nozzle, a sliding sleeve arranged on the outside of the connecting rod and fixedly connected to the mounting frame, a motor fixed at one end of the mounting frame and a special-shaped interference block arranged at the output end of the motor, the gear is meshed with the rack, one of the connecting rods of the rack is in conflict with the special-shaped interference block, and the outer sleeve of the other connecting rod of the rack is provided with a reset spring.

[0008] The beneficial effect of this improvement is as follows: the special-shaped resistance block is driven to rotate by a motor, and when the special-shaped resistance block squeezes the connecting rod on the rack during rotation, the rack moves laterally, driving the gears on multiple atomizing nozzles to rotate, and the gears drive the atomizing nozzles to rotate along the connecting pipe to achieve swinging, and when the special-shaped resistance block rotates to the point where the connecting rod on the rack gradually disengages, the spring drives the rack to reset, and the rack drives the gear to reset the atomizing nozzle.

[0009] To further increase the mist coverage area:

[0010] As a further improvement of the above technical solution: the output end of the atomizing nozzle is arranged to be inclined upward.

[0011] The beneficial effect of this improvement is that the upward tilted setting can make the atomized water of the atomizing nozzle cover a wider area.

[0012] In order to make the relative rotation between the atomizing nozzle and the mounting bracket smoother:

[0013] As a further improvement of the above technical solution: the atomizing nozzle is connected to the mounting frame via a bearing.

[0014] The beneficial effect of this improvement is that the bearing can make the relative rotation between the atomizing nozzle and the mounting frame smoother.

[0015] In order to make the reciprocating extrusion of the connecting rod by the special-shaped resistance block smoother:

[0016] As a further improvement of the above technical solution: the shape of the special-shaped interference block is elliptical.

[0017] The beneficial effect of this improvement is that the ellipse has a certain curvature, which can make the extrusion process and the reset process of the connecting rod smoother.

[0018] In order to ensure that the water in the water pipe has sufficient pressure:

[0019] As a further improvement of the above technical solution: a water pump is provided at the input end of the water delivery pipe.

[0020] The beneficial effect of this improvement is that the water pump can keep the water in the water pipe at a certain pressure for transportation.

[0021] In order to fully ensure the dust reduction effect:

[0022] As a further improvement of the above technical solution: the spacing distance between the output ends of the water pipes is 1m.

[0023] The beneficial effect of this improvement is that the 1m interval setting can ensure the dust reduction effect while reducing the number of atomizing nozzles as much as possible. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to enable those skilled in the art to better understand the technical solution of the utility model, the utility model is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the utility model.

[0030] like Figure 1-4As shown, a dust suppression device for construction engineering comprises a water pipe 2 installed on a fence 1, and an atomizing nozzle 6 which is rotatably and sealably connected to a plurality of output ends of the water pipe 2 evenly spaced apart via a connecting pipe 5. A horizontally arranged mounting frame 4 is fixedly connected to the fence 1, and the atomizing nozzle 6 is rotatably connected to the mounting frame 4. A driving assembly for driving the atomizing nozzle 6 to reciprocate along the axis of the connecting pipe 5 is also provided on the mounting frame 4. In a normal dust suppression process, water from the water pipe 2 on the fence 1 is transported to the atomizing nozzle 6 through the connecting pipe 5, and the atomizing nozzle 6 sprays the water in the form of water mist, which makes the dust fall after contacting the water. A single water pipe 2 is provided with a plurality of output ends, thereby realizing a plurality of linear The arranged atomizing nozzles 6 atomize water synchronously. Since there is a certain distance between two adjacent atomizing nozzles 6, and the atomized water is generally sprayed out in a fan shape, the atomization between the two adjacent atomizing nozzles 6 is not sufficient, resulting in poor dust treatment effect. By adding a driving component to drive the atomizing nozzles 6 to swing, sufficient atomization can be performed between the adjacent atomizing nozzles 6, thereby increasing the dust reduction effect. The driving component includes a rack 9 with connecting rods 11 at both ends, a gear 7 fixed to the outside of the atomizing nozzle 6, a ring sleeve 10 slidingly arranged on the outside of the connecting rod 11 and fixedly connected to the mounting frame 4, a motor 13 fixed to one end of the mounting frame 4, and a special-shaped resistance block 14 arranged at the output end of the motor 13. The wheel 7 is meshed with the rack 9, and one of the connecting rods 11 of the rack 9 is in conflict with the special-shaped interference block 14. The outer sleeve of the other connecting rod 11 of the rack 9 is provided with a reset spring 12, and the special-shaped interference block 14 is driven to rotate by the motor 13. When the special-shaped interference block 14 squeezes the connecting rod 11 on the rack 9 during rotation, the rack 9 moves laterally, driving the gears 7 on the multiple atomizing nozzles 6 to rotate, and the gear 7 drives the atomizing nozzle 6 to rotate along the connecting pipe 5 to achieve swing. When the special-shaped interference block 14 rotates to the connecting rod 11 on the rack 9 and gradually disengages, the spring drives the rack 9 to reset, and the rack 9 resets the atomizing nozzle 6 by driving the gear 7, and the atomizing nozzle 6 The output end is tilted upward, and the tilted upward setting can make the atomized water of the atomizing nozzle 6 cover a wider area. The atomizing nozzle 6 is connected to the mounting frame 4 through a bearing 8, and the bearing 8 can make the relative rotation between the atomizing nozzle 6 and the mounting frame 4 smoother. The shape of the special-shaped resistance block 14 is elliptical, and the ellipse has a certain curvature, which can make the squeezing process and the resetting process of the connecting rod 11 smoother. The input end of the water pipe 2 is provided with a water pump 3, and the water pump 3 can keep the water in the water pipe 2 at a certain pressure for transportation. The output ends of the water pipe 2 are spaced apart at a distance of 1m. The 1m interval can ensure the dust reduction effect and reduce the number of atomizing nozzles 6 as much as possible.

[0031] The working principle and use process of the utility model are as follows: when using the device, first, the water pump 3 supplies water to the water pipe 2, and the water in the water pipe 2 enters the atomizing nozzle 6 through the connecting pipes 5 on the multiple output ends, and the atomized water is sprayed out through the atomizing nozzle 6, wherein the atomizing nozzle 6 and the connecting pipe 5 are connected in a rotating seal, and its specific structure is a technology well known to those skilled in the art, and will not be elaborated in detail here. During the atomization process, the motor 13 drives the special-shaped resistance block 14 to rotate slowly, and the special-shaped resistance block 14 rotates by the connecting rod 1 1 is squeezed, driving the rack 9 to move laterally, and at the same time the reset spring 12 is compressed, the rack 9 drives the gear 7 to rotate, and the gear 7 drives the atomizing nozzle 6 to rotate, thereby realizing the angular swing of the atomizing nozzle 6, and when the special-shaped resistance block 14 is separated from the squeezing of the connecting rod 11, the reset spring 12 extends to drive the rack 9 to reset, thereby realizing the reset of the angle of the atomizing nozzle 6, and by adjusting the angles of multiple atomizing nozzles 6 at the same time, the atomization range can be fully covered, avoiding the dead angles between adjacent atomizing nozzles 6 that cannot be covered, resulting in poor dust reduction effect.
