[0036] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments:

[0037] Example:

[0038] like Figures 1 to 8 As shown, a dust purification device for municipal road engineering construction includes a base 1, a movable component is provided at the bottom of the base 1, a support plate 2 is provided at the middle of the top of the base 1, the top of the support plate 2 is rotatably connected to the support plate 2 3, the top of the support plate 2 3 is vertically rotatably connected to the fixed cylinder 4, the left end of the fixed cylinder 4 is detachably connected to the induced draft hood 5, the right end of the fixed cylinder 4 is detachably connected to the spray cylinder 6, the induced draft hood 5 is detachably connected to the purification component, the fixed cylinder 4 is provided with an induced draft component, the top of the fixed cylinder 4 is provided with an adjusting component, the top of the adjusting component is provided with a solar panel 7, the spray cylinder 6 is connected to a water pump 8 fixedly installed on the top of the base 1, the solar panel 7 is electrically connected to the battery (not shown in the figure) of the device, and the battery provides electrical energy for the electrical appliances of the device.

[0039] Since the ground at highway construction sites is often not flat enough, the dust purification device is prone to rollover during movement. To prevent the dust purification device from rolling over during movement, the mobile assembly provided in the present invention includes a bevel gear 1 9, which is meshed with two symmetrically arranged bevel gears 2 10. The bevel gear 1 9 and the bevel gear 2 10 are both rotatably connected to the base 1 through a fixed plate, and the bevel gear 2 10 is provided with two symmetrically arranged universal wheels 11 through a connecting rod. When the device moves, the uneven road surface can drive the movably connected connecting rod to rotate adaptively, thereby driving the bevel gear 2 10 and the bevel gear 1 9 to make corresponding adaptive adjustments, ensuring that the base 1 will not tilt significantly, and preventing the problem of rollover.

[0040] To further ensure that the device can be stably fixed on the ground when in use, the mobile assembly also includes four electric telescopic support rods 12 fixed to the top of the base 1 and extending to the bottom of the base 1. When the device moves to the working area, the electric telescopic support rods 12 are controlled to support the ground so that the universal wheels 11 leave the ground.

[0041] On the basis of the above scheme, the induced draft component includes a motor 13 disposed at the top of the fixed cylinder 4, the output end of the motor 13 is provided with a bevel gear 3 14 located in the fixed cylinder 4 and rotatably connected to the fixed cylinder 4, the bevel gear 3 14 is meshed with a bevel gear 4 15 coaxially disposed with the fixed cylinder 4, the bevel gear 4 15 is rotatably connected with the fixed cylinder 4 through a connecting rod, the bevel gear 4 15 is coaxially provided with two blades 16 through a rotating shaft, and the two blades 16 are distributed at both ends of the fixed cylinder 4. When the motor 13 is started, the motor 13 can drive the bevel gear 1 9 to rotate, the rotating bevel gear 1 9 drives the bevel gear 2 10 to rotate, and then drives the blades 16 to rotate, and the rotating blades 16 can attract the dust-containing gas in the air into the induced draft hood 5, filter the dust through the purification component, and then discharge the clean gas through the spray cylinder 6.

[0042] On the basis of the above scheme, the purification component includes a mounting cover 17 that is detachably rotatably connected to the induced draft hood 5, and the mounting cover 17 is detachably connected to a filter screen 18 close to the induced draft hood 5. The two sides of the inner cavity cross section of the induced draft hood 5 are concave arc edges, and a one-way valve 19 is provided in the middle of the inner cavity of the induced draft hood 5. The air containing dust enters the dust temporary storage cavity surrounded by the one-way valve 19, the induced draft hood 5 and the filter screen 18 through the one-way valve 19. Since the inner cavity radius of the induced draft hood 5 is large at both ends and small in the middle, the dust can be induced to generate a vortex in the dust temporary storage cavity, thereby improving the filtering effect of the filter screen 18 on the dust.

[0043] In order to further improve the filtering effect of the filter 18, on the basis of the above scheme, an inner gear 20 is provided at one end of the mounting cover 17 away from the filter 18, the inner gear 20 is meshed with a spur gear 1 21, the spur gear 1 21 is meshed with a spur gear 2 22 coaxially fixedly connected with the bevel gear 4 15, and the spur gear 1 21 and the spur gear 2 22 are both rotatably engaged with the fixed cylinder 4. When the air is induced, the rotating bevel gear 4 15 can drive the spur gear 2 22 to rotate in the same direction, and drive the inner gear 20 to rotate in the opposite direction with the cooperation of the spur gear 1 21, and then drive the filter 18 to rotate in the opposite direction, so that the filter 18 can contact the gas in different areas, and improve the filtering effect of the filter 18.

[0044] In order to remove the dust accumulated on the filter screen 18 and further improve the filtering effect of the filter screen 18, a brush plate 23 penetrating the filter screen 18 is coaxially provided on the spur gear 21, and a sewage pipe 24 close to the filter screen 18 and extending to the inside of the sewage hood 5 is provided at the bottom of the induced draft hood 5. The sewage pipe 24 is connected to a collecting box 25 arranged on the top of the base 1 through a hose, and the input end of the water pump 8 is connected to a water tank 26 arranged on the top of the base 1 through a hose. The input end of the water pump 8 is connected to two groups of rotating nozzles 27 through a tee pipe and a hose. One group of rotating nozzles 27 is distributed in a circular array at one end of the spray barrel 6, and one group of rotating nozzles 27 is arranged on the side of the brush plate 23 away from the filter screen 18. A solenoid valve (not shown in the figure) is provided at the connection between the tee pipe and the rotating nozzle 27. When the induced draft assembly is used for dust purification, the spur gear 1 21 can drive the brush plate 23 to rotate, so that the filter 18 and the brush plate 23 rotate in opposite directions, and the dust on the filter 18 can be cleaned off, and the dust on the inner wall of the dust storage chamber can be cleaned by the rotating nozzle 27, and the sewage flows into the collection box 25 through the sewage pipe 24. When the spray barrel 6 is used for dust purification, the water pump 8 is started, and the water pump 8 pumps the water in the water tank 26 into the hose to the rotating nozzle 27 for spraying.

[0045] During operation, it is often necessary to adjust the horizontal angle of the fixed cylinder 4 according to the construction situation. In order to ensure that the angle of the fixed cylinder 4 does not shift during long-term operation, a self-locking component is provided between the support plate 1 2 and the support plate 2 3. The self-locking component includes a groove 28 provided on the top of the support plate 2, and the inner wall of the groove 28 is rotatably clamped with a transmission plate 29 and a transmission rod 30. The transmission rod 30 and the transmission plate 29 are movably connected. The transmission rod 30 is slidably clamped with a sliding cylinder 31. The bottom of the sliding cylinder 31 is connected to the bottom of the groove 28 through a spring. The top of the sliding cylinder 31 and the bottom of the transmission plate 29 are provided with four hemispherical grooves 32 that are distributed in a circle and correspond to each other. Balls 33 are movably connected in two corresponding hemispherical grooves 32. The sliding distance of the sliding cylinder 31 is less than the radius of the hemispherical grooves 32. When the horizontal angle of the fixed cylinder 4 needs to be rotated, a tangential force is applied to the fixed cylinder 4 to drive the transmission plate 29 to rotate. The transmission plate 29 can drive the sliding cylinder 31 to slide downward while rotating under the limitation of the hemispherical groove 32, the ball 33 and the transmission rod 30. The sliding cylinder 31 sliding downward squeezes the spring. When the horizontal angle is adjusted, the applied tangential force is withdrawn, the compressed spring recovers, and the rotating plate has a limiting effect.

[0046] In addition, a worm wheel can be sleeved on one end of the transmission rod 30 near the bottom, and the worm wheel is meshed with a worm that is rotatably engaged with the support plate 2, and the rotating plate is further self-locked and limited by the self-locking structure of the worm and worm wheel; and a support rod is provided between the support plate 1 2 and the support plate 2 3, and the support rod is a telescopic structure with adjustable height, which is the prior art.

[0047] During operation, it is often necessary to adjust the vertical angle of the fixed cylinder 4 according to the construction conditions. Therefore, a bevel gear five 34 is rotatably connected to the top of the support plate two 3 through the fixed plate. The bevel gear five 34 is meshed with a bevel gear six 35. A threaded rod 36 is passed through the bevel gear six 35. The threaded rod 36 located above the bevel gear six 35 is threadedly connected with a slider 37. The threaded rod 36 located below the bevel gear six 35 is rotatably connected to the bevel gear five 34 through a rotating shaft. The slider 37 is movably connected to one end of the fixed cylinder 4, and the other end of the fixed cylinder 4 is hinged to the support plate two 3. Rotating the bevel gear five 34 can drive the bevel gear six 35 to rotate, and drive the threaded rod 36 to rotate, so that the slider 37 slides on the threaded rod 36, and then the fixed cylinder 4 rotates around the hinge of the support plate two 3.

[0048] In order to better collect solar energy, the adjustment component of the present invention includes a support frame 38 fixed to the top of the fixed cylinder 4, a fixed frame 39 is provided on the top of the support frame 38, the fixed frame 39 is rotatably connected to the mounting frame 40, the mounting frame 40 is rotatably connected to the rotating rod 41, a bevel gear seven 42 is provided on the top of the rotating rod 41, the bevel gear seven 42 is meshed with a bevel gear eight 43 rotatably connected to the mounting frame 40, the solar panel 7 is arranged on the top of the bevel gear eight 43 through a rotating shaft, the mounting frame 40 and the rotating rod 41 are respectively provided with a follower 45 at the bottom, the follower 45 is meshed with an active member 44 rotatably connected to the fixed frame 39, and the active member 44 is coaxially provided with a motor two 46.

[0051] Further, the vertical transmission connection relationship has two helical gears meshing vertically, and both the driving member 44 and the driven member 45 are helical gears;

[0052] Furthermore, the vertical transmission connection relationship has two bevel gears meshing with each other, and both the driving member 44 and the driven member 45 are bevel gears.

[0053] When the motor 2 46 connected to the transmission rod 30 is started, with the cooperation of the active member 44 and the driven member 45, the transmission rod 30 can be driven to rotate, and then the bevel gear 7 42 and the bevel gear 8 43 can be driven to rotate, thereby driving the solar panel 7 to rotate around the center line of the bevel gear 8 43; when the motor 2 46 connected to the mounting frame 40 is started, with the cooperation of the active member 44 and the driven member 45, the mounting frame 40 can be driven to rotate, thereby driving the solar panel 7 to rotate around the center line of the mounting frame 40, thereby realizing all-round adjustment of the angle of the solar panel.

[0054] In addition, photo sensors can be set in different directions on the solar panel 7, and a control panel can be installed on the device so that all electrical components (motor 1 13, motor 2 46, water pump 8, solenoid valve and photo sensor, etc.) are electrically connected to the control panel.

The angle of the solar panel 7 is adjusted by adjusting the assembly so that it faces the sunlight.

[0057] Select a suitable dust purification device according to the actual situation of the construction site. When water sprinkling purification is selected, start the water pump 8, and control the output end of the water pump 8 to only connect to the rotating nozzle 27 installed on the spray barrel 6 through the solenoid valve to purify the dust by sprinkling. When induced draft filtration and dust purification is selected, start the motor 13, which can drive the bevel gear 19 to rotate, and the rotating bevel gear 19 drives the bevel gear 2 10 to rotate, and then drives the fan blade 16 to rotate. The rotating fan blade 16 can attract the dust-containing gas in the air into the induced draft hood 5, and the dust-containing gas can be filtered through the filter 18, and then the clean gas is discharged through the spray barrel 6; at the same time, the spur gear 121 can drive the brush plate 23 to rotate, so that the filter 18 and the brush plate 23 rotate in opposite directions, and the dust on the filter 18 can be cleaned off.
