Description

Technical Field

[0001] The invention relates to the field of municipal devices, and in particular to a municipal dust reduction device. Background Art

[0002] With the development of industry, dust pollution is becoming more and more serious. Due to the long construction period and large area of ​​municipal engineering, the dust pollution in its construction site is also becoming more and more serious. In order to improve the urban air quality, municipal dust reduction devices have come into being. At present, most municipal dust reduction devices use the method of spraying atomized water vapor into the air to achieve the purpose of dust reduction. The atomized water vapor reacts with the suspended particles, which can make the particles settle or be humidified, reducing their concentration in the air. Therefore, a municipal dust reduction device plays an important role in improving the urban air quality.

[0003] After searching, the patent with authorization publication number CN219118041U discloses a dust prevention device for municipal road construction, including a base, universal wheels, a pushing frame, a spraying device and a cleaning mechanism.

The spraying device absorbs the dust and the dust falls down, and the cleaning mechanism collects and cleans the dust.

[0004] The dust-proof device designed by the above patent can absorb the dust by spraying water, and the dust will fall due to gravity, and then be sucked into the dust removal box by the suction fan through the wind hood. The dust inside the dust removal box is absorbed by water, and the motor drives the cleaning roller to rotate to sweep the absorbed dust into the push plate. The push plate is kept on the road surface by the cooperation of the telescopic rod and the spring, thereby achieving the effect of dust reduction and cleaning by spraying water. However, since the spray adjustment device is far away from the push handle of the operating device, the device needs to be stopped each time the spray angle is adjusted, which makes the whole device more troublesome to use and leads to low efficiency of urban dust reduction. Therefore, it is necessary to design a municipal dust reduction device that is easy to operate in view of the shortcomings of the prior art. Summary of the invention

[0037] like Figure 5 and Figure 6 As shown, it also includes a guide frame 231 and a fixing rod 232. The guide frame 231 is fixedly connected to the top of the support seat 23. The guide frame 231 is provided with an arc-shaped sliding opening adapted to the atomizer 6. The fixing rod 232 is fixedly connected to the guide frame 231.

[0038] like Figure 1 As shown, a water inlet is provided at the top of the water tank 3 , and a thread is provided on the outside of the water inlet to fit an external water injection pipe through the thread, so that water used for dust reduction can be easily injected into the water tank 3 .

[0039] like Figure 1 , Figure 5 and Figure 6As shown, the atomizer 6 includes a connector 61, a sliding rod 62, an atomizing nozzle 63 and an elastic hose 64. The connector 61 is fixedly installed on the top of the fixed rod 232, and the connector 61 is adapted to different pipes on the water pressure regulating valve 5. The sliding rod 62 is slidably connected to the guide frame 231, and it is adapted to the arc-shaped sliding mouth of the guide frame 231. The atomizing nozzle 63 is fixedly installed on the top of the sliding rod 62, and the elastic hose 64 is connected between the connector 61 and the atomizing nozzle 63. The water drawn in through the connector 61 will spray out water mist after passing through the atomizing nozzle 63, and the atomizing nozzle 63 slides in the arc-shaped sliding mouth of the guide frame 231. With the cooperation of the elastic hose 64, the atomizing nozzle 63 sprays water mist at different angles.

[0040] like Figure 2 , Figure 5 and Fig.13 As shown, each pipe on the water pressure regulating valve 5 and the connecting point of the water pipe 31 are provided with an annular waterproof gasket, which can be sealed to fit the inner wall diameter of the water pipe 31. When different pipes on the water pressure regulating valve 5 and the water pipe 31 are connected, their sealing is guaranteed. The water tank 3 also includes a water level window 32, which is arranged on the side wall of the water tank 3. The water level window 32 can facilitate observation of the remaining water amount in the water tank 3.

[0041] like Figure 5 and Figure 6 As shown, it also includes a rack bar 71, a water blocking valve 72 and a spur gear 73. The rack bar 71 is provided with multiple and respectively fixedly connected to the outer sides of multiple pipes of the water pressure regulating valve 5. The water blocking valve 72 is rotatably connected to the inside of the connector 61, and its rotating shaft passes through the outside of the side wall of the connector 61. The spur gear 73 is installed on the rotating shaft of the water blocking valve 72. The spur gear 73 and the rack bar 71 are meshed with each other, and the number of teeth of the spur gear 73 is twice that of the rack bar 71. Initially, the spur gear 73 is located in the middle of the rack bar 71, and the water blocking valve 72 is completely opened in the connector 61. When the water pressure regulating valve 5 is rotated for adjustment, the pipeline thereon will drive the corresponding rack bar 71 to drive the spur gear 73 to rotate, so that the rotating spur gear 73 drives the water blocking valve 72 to intermittently block the connector 61, so as to control the water flow to stop and avoid waste when the water pressure regulating valve 5 is switched.

[0042] When municipal dust reduction operations are required, the user pushes the device to the road surface where dust reduction is required by holding the pushing frame 21, and injects the required water into the water tank 3 in advance. When the water tank 3 is filled with a certain amount of water, the pushing frame 21 is operated again. At this time, under the transportation action of the universal wheels at the bottom of the movable seat 1, the movable seat 1 can drive the base 2 and various components thereon to move forward. When spraying water to reduce dust, the user can conveniently twist the rotating sleeve 41 while holding the pushing frame 21. The rotated rotating sleeve 41 will drive the driving shaft 43 to rotate through the pulley 42 and the action of the belt. When the driving shaft 43 rotates, the bevel gears 44 at two locations on the driving shaft 43 and the water pressure regulating valve 5 will mesh, and driven by the rotating bevel gear 44, the water pressure regulating valve 5 will rotate, and the pipe on the water pressure regulating valve 5 will be aligned with the water supply pipe 31. At this time, the water pump in the water tank 3 is started again, and water is pumped into the water supply pipe 31 through the water pump. The pumped water will pass through the water supply pipe 31 flows into the water pressure regulating valve 5, and after flowing through the water pressure regulating valve 5, the water will enter the connector 61, and finally flow into the atomizing nozzle 63 through the elastic hose 64, and finally spray water mist outward through the atomizing nozzle 63. At this time, the atomizing nozzle 63 follows the entire device to continuously move forward, thereby performing dust reduction operations on municipal streets. When it is necessary to adjust the size of the water mist sprayed, the rotating sleeve 41 is twisted again, and similarly, the pulley 42 and the bevel gear 44 interact with each other in turn to drive The water pressure regulating valve 5 continuously switches pipelines and aligns the water delivery pipe 31. During this switching process, the rack bars 71 at different pipelines will mesh and drive the spur gear 73 to rotate. When a section of the rack bar 71 moves away from the spur gear 73, since the number of teeth of the rack bar 71 is half of that of the spur gear 73, the rotating spur gear 73 will drive the water blocking valve 72 to rotate 90 degrees. When the water pressure regulating valve 5 switches different pipelines, the water blocking valve 72 will temporarily block the connector 61 to prevent water from continuously flowing out and causing waste.

[0043] Embodiment 2: Based on embodiment 1, Figure 7 and Figure 8 As shown, the water pressure regulating valve 5 is provided with an anti-rotation component 8, and the anti-rotation component 8 includes a ratchet 81 and a pawl 82. The ratchet 81 is installed on the rotating shaft of the water pressure regulating valve 5, and the pawl 82 is installed on the mounting frame 22 through a torsion spring and is used to adapt to the ratchet 81. With the mutual cooperation of the ratchet 81 and the pawl 82, the water pressure regulating valve 5 can rotate stably and switch to different pipelines, and the water pressure regulating valve 5 can only rotate in one direction to prevent the water pressure regulating valve 5 from being affected by external vibrations.

[0044] like Figure 1 , Fig. 9 and Fig.11As shown, a swing assembly 9 is provided on the support seat 23, and the swing assembly 9 includes a motor 91, a swing rod 92, a driven rod 93 and a transmission frame 94. The motor 91 is installed inside the support seat 23, and the output shaft of the motor 91 passes through the top of the support seat 23 outwardly, the swing rod 92 is fixedly connected to the output shaft of the motor 91, and the driven rod 93 is rotatably installed on the top of the support seat 23. The upper part of the support seat 23 is connected to the transmission frame 94, and a slide groove is provided in the middle of the transmission frame 94. The top of the swing rod 92 is connected to a sliding shaft. The sliding rod 62 and the sliding shaft are both located in the sliding groove on the transmission frame 94. The transmission frame 94 is rotatably connected between the swinging rotating rod 92 and the driven rotating rod 93, and the transmission frame 94 and the sliding rod 62 are slidably connected. The motor 91 drives the swinging rotating rod 92 to rotate reciprocatingly, and cooperates with the driven rotating rod 93 to drive the transmission frame 94 to reciprocate, so that the sliding rod 62 can follow the transmission frame 94 to reciprocate, so that the sliding rod 62 can reciprocate and drive the atomizing nozzle 63 to change its angle under the guidance of the sliding mouth on the guide frame 231.

[0045] When the water pressure regulating valve 5 is continuously rotating to switch the pipeline, the rotating shaft of the water pressure regulating valve 5 will drive the ratchet 81 to rotate, and at the same time, the ratchet 82 will be squeezed on the ratchet 81 under the action of the torsion spring. Whenever the water pressure regulating valve 5 rotates a certain angle, the ratchet 82 will act on the ratchet 81, so that the ratchet 81 can limit the water pressure regulating valve 5 to rotate stably. When the dust suppression device continuously sprays water to suppress dust, the mobile seat 1 will encounter various undulating road surfaces, which may affect the adjustment of the water pressure regulating valve 5. At this time, the ratchet 81 cooperates with the ratchet 82, so that the water pressure regulating valve 5 can only rotate in one direction, thereby preventing the water pressure regulating valve 5 from being reversed due to external influences, thereby improving the stability of the water pressure regulating valve 5 after the switching of the water pressure regulating valve 5 to align with the water pipe 31. When it is necessary to adjust different spraying angles of the atomizer 6, the motor 91 can be started. The motor 91 drives the swinging rotating rod 92 to rotate continuously through the output shaft, and then the rotating rotating rod drives the transmission frame 94 to move back and forth. Under the guidance of the driven rotating rod 93, the reciprocating transmission frame 94 can drive the sliding rod 62 to move repeatedly. At this time, the repeatedly moving sliding rod 62 will drive the atomizing nozzle 63 to move, and under the guidance of the sliding mouth on the guide frame 231, the atomizing nozzle 63 can adjust the angle relative to the connecting head 61. At this time, since an elastic hose 64 is provided between the connecting head 61 and the atomizing nozzle 63, the atomizing nozzle 63 can be flexibly swung without affecting the normal dust reduction effect of the atomizing nozzle 63.

[0046] Embodiment 3: Based on embodiment 2, Figure 1 and Fig.11As shown, a protective component 10 is also provided on the base 2, and the protective component 10 includes a rotating wheel 101 and a rubber pad 102. The rotating wheel 101 is provided with two and is rotatably connected to the right top corner of the base 2 respectively, and the rubber pad 102 is correspondingly sleeved on the outer side of the rotating wheel 101. The rubber pad 102 protects the side of the base 2. When the base 2 collides with the wall, the entire device is buffered and shock-absorbing.

[0047] like Fig.11 and Fig.12 As shown, a lifting component 11 is provided on the moving seat 1, and the lifting component 11 includes a piston cylinder 111, a piston rod 112 and a cylinder top 113. The piston cylinder 111 is installed inside the moving seat 1, and the piston rod 112 is installed in the piston cylinder 111, and the piston rod 112 and the pushing frame 21 are located on the same side. The cylinder top 113 is provided with two cylinders that are fixedly installed inside the moving seat 1, and the cylinder top 113 and the piston cylinder 111 are connected. A telescopic shaft is provided inside the cylinder top 113, and the telescopic shaft is connected to the base 2. The piston cylinder 111 is manually blown continuously through the piston rod 112 to increase the air pressure inside the piston cylinder 111, and the air pressure pushes the telescopic shaft inside the cylinder top 113 to lift the base 2 upward, thereby realizing the adjustment of the height between the moving seat 1 and the base 2, thereby adjusting the dust reduction height of the entire device.

[0048] When the push frame 21 is operated to continuously push the device forward to spray water mist to reduce dust, it is inevitable that the mobile seat 1 will encounter collisions when driving the base 2 to move. When an object collides, the colliding object will first contact the rotating wheel 101 and be buffered by the rubber pad 102 under the impact force from the object. At this time, under the rotation of the rotating wheel 101, the mobile seat 1 and the base 2 can still be flexibly turned, reducing the impact of the device on the entire device when it collides, and avoiding the situation where it cannot move due to collision when turning a corner. When it is necessary to adjust the height of the water mist sprayed by the atomizer 6, the piston rod 112 is directly pulled out and continuously pulled on the base 2, and the piston The rod 112 will continuously fill the piston cylinder 111 with gas, and the influx of gas will continuously increase the air pressure inside the piston cylinder 111. At this time, the continuously increasing air pressure inside the piston cylinder 111 will act on the two cylinder tops 113. Finally, under the joint action of the cylinder tops 113, the telescopic axis inside the cylinder tops 113 is used to support the base 2 upward, so that the base 2 can be supported upward from the moving base 1, thereby enabling the base 2 to drive the various components thereon, such as the pushing frame 21, the mounting frame 22 and the supporting base 23, to be lifted upward, thereby achieving the effect of lifting the atomizing nozzle 63, so that the device can be suitable for different dust reduction heights.

[0049] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
