Description

Technical Field

[0001] The present invention generally relates to the field of operation and transportation, and specifically relates to a dust removal device for municipal road construction. Background Art

[0002] During the process of municipal road construction, dust pollution is an urgent problem to be solved, which will not only pollute the environment but also affect the physical health of construction workers. Dust removal devices play an important role in this field. Among them, the fog cannon has been widely used due to its high-efficiency dust removal and dust suppression effect.

[0003] Currently, the common platforms equipped with fog cannons are mainly divided into two types: vehicle-mounted and portable. The vehicle-mounted platform has the advantages of fast moving speed and wide coverage, but it has the problem of insufficient flexibility in some narrow construction sites or areas that require fine operation. The portable platform well makes up for this defect. It mainly uses a platform vehicle as a carrier, installs a fog cannon on the platform vehicle, and can realize related operations such as dust removal and dust suppression by manually pushing the platform vehicle, and can flexibly adapt to this complex environment.

[0004] However, the existing portable platform vehicles have obvious deficiencies in actual applications. Since heavy objects such as water tanks need to be carried on the platform vehicle, the weight of these heavy objects will significantly increase the load of the staff. The staff need to spend more effort when pushing the platform vehicle, resulting in difficult displacement of the platform vehicle, thus greatly reducing the displacement efficiency of the platform vehicle. This not only increases the labor intensity of the staff but also affects the progress and efficiency of municipal road construction to a certain extent.

[0005] In summary, the existing portable fog cannon-mounted platforms in municipal road construction have low displacement efficiency due to large loads, and there is an urgent need for a dust removal device for municipal road construction that can solve this problem. Summary of the Invention

[0006] In view of the above problems existing in the prior art, according to the present invention, a dust removal device for municipal road construction is provided, including: a base body, a moving device fixed to the bottom of the base body; a support frame fixed to the base body; a fog cannon connected to the inside of the support frame and rotatably connected to the support frame; a liquid supply assembly fixed to the inside of the base body and connected to the fog cannon; a first motor located on the rotating shaft of the fog cannon and the support frame, and its output shaft is fixed to the fog cannon; a longitudinal displacement mechanism fixed to the inside of the support frame and driving the fog cannon to displace towards the inside of the base body; a docking seat fixed to the tail inside the base body for docking with the output end of the fog cannon; and a pressurized nozzle flexibly connected to one side of the docking seat.

[0007] With the above technical features, the two-position operation of the fog cannon machine in the working position and the storage position can be realized. When the fog cannon machine is in the storage position, the reverse force generated when it is turned on can provide assistance for the displacement of the base body, so as to reduce the labor intensity of manually operating the base body. Moreover, the reverse force not only helps the movement of the base body, but also sprays fog backward through the pressure nozzle, and dust is reduced while moving, improving the dust reduction effect.

[0008] In some embodiments, the longitudinal displacement mechanism includes a screw rod, which is vertically arranged on one side of the support frame and is rotatably connected to the support frame at both ends; a second motor, which is located at one end of the screw rod and is fixed to the support frame, and its output shaft is coaxially fixed to the screw rod; a driving block, which is slidably connected to the support frame and is penetrated by the screw rod and is threadedly connected to the screw rod. Thus, the second motor drives the screw rod to rotate, and through the mutual sliding of the driving block and the support frame, the fog cannon machine is driven to displace along the height direction of the support frame, thereby adjusting the lifting of the fog cannon machine and realizing the conversion of different working positions of the fog cannon machine between the working position and the storage position.

[0009] In some embodiments, an annular airbag is fixed at the output port of the fog cannon machine, and a plurality of air pipes are arranged on the periphery of the fog cannon machine. One end of the air pipe is communicated with the inside of the fog cannon machine, and the other end of the air pipe is communicated with the inside of the airbag. Thus, when the fog cannon machine is working, part of the air will be transported into the airbag through the air pipe. After the airbag is filled, the cross-sectional area of the output port of the fog cannon machine is reduced by the increase in its volume, thereby indirectly increasing the wind pressure and the air flow velocity, and then affecting the dispersion range of the fog; when the fog cannon machine is completely stored in the base body, after the airbag is inflated, it will fill the gap between the port of the fog cannon machine and the port of the docking seat, thereby reducing the gas leakage between the output port of the fog cannon machine and the docking seat.

[0010] In some embodiments, a deflector is inclined and fixed at the connection of the air pipes inside the fog cannon machine for guiding the flowing air to the end of the air pipe. Thus, the deflector plays a role in guiding the air, ensuring the high efficiency and fullness of the airbag filling.

[0011] In some embodiments, the airbag includes an airtight bag wall and a semi-permeable bag wall connected to the airtight bag wall, and the semi-permeable bag wall faces away from the port of the fog cannon machine. Thus, while ensuring the complete filling of the airbag, the leakage of the airbag gas is delayed, ensuring that the airbag is always in a bulging state, and the gas leakage is more uniform through the semi-permeable bag wall, playing a role in limiting and guiding the flow of the fog passing through the port of the fog cannon machine as a whole.

[0012] In some embodiments, the liquid supply assembly includes a water tank fixed inside the base body, a water pump interconnected with the inside of the water tank, a first liquid supply pipe connected to the output port of the water pump, the other end of the first liquid supply pipe being connected to the end of the fog cannon, and a first electromagnetic valve being provided on the first liquid supply pipe.

[0013] Thus, through the operation of the water pump, the liquid supply to the fog cannon is realized, and the effect of dust reduction is further achieved.

[0014] In some embodiments, the output port of the water pump is connected to a second liquid supply pipe, the other end of the second liquid supply pipe extending to a pressure nozzle, multiple second atomizing nozzles being mounted on the pressure nozzle, the end of the second liquid supply pipe being interconnected with each second atomizing nozzle, and a second electromagnetic valve being provided on the second liquid supply pipe. Thus, when the fog cannon is in the internal environment of the base body, the fog injection of the fog cannon itself can be closed through the first electromagnetic valve, mainly providing strong air flow, and second atomizing nozzles are provided at the end of the pressure nozzle to achieve the effect of atomized dust reduction, so as to avoid the liquid backflow caused by the fog of the fog cannon itself splashing into the high-pressure nozzle, resulting in unnecessary waste of liquid.

[0015] In some embodiments, one end of the pressure nozzle is rotatably connected to the base body, and a driving rotation mechanism is provided on one side of the pressure nozzle. The driving rotation mechanism includes an arc-shaped guide rail fixed to the base body and having an arc-shaped rack provided therein; a third motor fixed to one side of the pressure nozzle; and a first gear coaxially fixed to the output shaft of the third motor and meshing with the arc-shaped rack. Thus, the angle adjustment of the pressure nozzle is realized to achieve the change of different working positions of the dust removal device. When the pressure nozzle faces the ground, during the displacement of the base body, the operations of dust blowing or leaf sweeping can be realized; when the pressure nozzle is horizontal, the loss of oblique acting force can be reduced, making the displacement of the base body more labor-saving; if the pressure nozzle is obliquely upward, during the displacement of the base body, the dust reduction effect can be realized again.

[0016] In some embodiments, the support frame is of a U-shaped structure. Thus, the support strength of the support frame itself is also improved, ensuring the stability of the fog cannon erection and the stability of the fog cannon operation.

[0017] It should be understood that the content described in the Summary of the Invention section is not intended to limit the key or important features of the embodiments of the present disclosure, nor is it used to limit the scope of the present disclosure. Other features of the present disclosure will become easily understood through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Next, the preferred embodiments (or implementation manners) of the present invention will be described in detail with reference to the accompanying drawings.

[0021] Next, refer to Figures 1 - 8 to describe a dust removal device for municipal road construction according to an embodiment of the present invention.

[0022] Figure 1 Shows a schematic diagram of the overall structure of a dust removal device for municipal road construction according to an embodiment of the present invention. Refer to Figure 1As shown in the figure, a dust removal device for municipal road construction provided in this embodiment includes a base body 1, which has a rectangular structure with an open upper end. Above the base body 1, there is a support frame 11 fixedly connected to the base body 1. The support frame 11 is a U-shaped frame with its opening facing the direction of the base body 1, and both ends are fixed to the opposite inner walls of the base body 1. Inside the support frame 11, there is a fog cannon 2, and the orientation of the port of the fog cannon 2 is adjusted by the rotation of the fog cannon 2. A longitudinal displacement mechanism 3 is also provided on the support frame 11 to drive the fog cannon 2 to move longitudinally along the support frame 11.

[0023] Figure 2 The figure shows a schematic diagram of the bottom structure of a dust removal device for municipal road construction according to an embodiment of the present invention. Refer to Figure 2 As shown in the figure, a moving device 12 is provided at the bottom of the base body 1. The moving device 12 mainly adopts a layout structure of a set of straight wheels 121 and a set of universal wheels 122. The set of universal wheels 122 is fixed at the two end corners of the front side of the bottom surface of the base body 1, and the set of straight wheels 121 is fixed at the two end corners of the rear side of the bottom surface of the base body 1. While achieving stable support for the base body 1, it also realizes the rotational displacement of the base body 1.

[0024] Furthermore, a U-shaped handle 13 is fixed to the front side of the base body 1, providing a gripping area for the operator and the base body 1, improving the operation efficiency of pulling the base body 1 to move, and also facilitating the adjustment of the rotation of the base body 1 and further adjusting the orientation of the port of the fog cannon 2, thereby adjusting the radiation range of the fog of the fog cannon 2.

[0025] Figure 3 The figure shows a schematic diagram of the connection structure of the fog cannon 2 in a dust removal device for municipal road construction according to an embodiment of the present invention. Refer to Figure 3 As shown in the figure, a first motor 21 is provided on the periphery of the fog cannon 2. The extension line of the center line of the first motor 21 intersects and is perpendicular to the center line of the fog cannon 2, and the output shaft of the first motor 21 is fixedly connected to the housing of the fog cannon 2.

[0026] The above-mentioned longitudinal displacement mechanism 3 includes two driving blocks 31, which are symmetrically arranged on both sides of the fog cannon 2. One of the driving blocks 31 is fixedly connected to the first motor 21, and the other driving block 31 is rotatably connected to the fog cannon 2; a screw rod 32 is vertically arranged on one side of the support frame 11, and the upper and lower ends of the screw rod 32 are rotatably connected to the support frame 11. The screw rod 32 passes through one of the driving blocks 31 and is threadedly connected to the driving block 31; a second motor 33 is arranged at the upper end of the screw rod 32, the main body of the second motor 33 is fixedly connected to the support frame 11, and the output shaft of the second motor 33 passes through the support frame 11 and is coaxially fixedly connected to the screw rod 32; a limiting slide rod 34 is vertically arranged on the other side of the fog cannon 2, and both ends of the limiting slide rod 34 are fixedly connected to the support frame 11, and the limiting slide rod 34 passes through the driving block 31 on the same side and is slidably connected to the driving block 31. By rotating the screw rod 32 forward or backward through the second motor 33, the driving block 31 is displaced along the direction of the screw rod 32 under limitation, and drives the fog cannon 2 to be displaced along the height direction of the support frame 11. Then, by rotating the first motor 21 forward or backward, the fog cannon 2 is driven to swing, realizing the adjustment of the orientation of the port of the fog cannon 2.

[0027] Figure 4 The schematic diagram of the internal structure of the base 1 in a dust removal device for municipal road construction according to an embodiment of the present invention is shown. Refer to Figure 4 As shown, in order to reduce the labor intensity of the staff in moving the base 1 and make reasonable use of the reaction force during the working process of the fog cannon 2, a reaction pushing platform is further arranged in the base 1. The reaction pushing platform includes a pair of docking seats 41. The docking seats 41 are tubular structures, and the diameter of one end port is larger than that of the other end port, and they are fixed in the tail area inside the base 1. When the fog cannon 2 is horizontally displaced into the base 1, the end with the larger port diameter of the docking seat 41 faces the output port of the fog cannon 2, and its caliber is larger than the diameter of the output port of the fog cannon 2. The other end of the fog cannon 2 is flexibly connected with a pressure nozzle 42 through a hose. The pressure nozzle 42 is arranged in the tail area of the base 1, so that when the fog cannon 2 works, air enters the fog cannon 2 at a high speed, flows out from the output port of the fog cannon 2, flows into the docking seat 41, and is sprayed out by the pressure nozzle 42. The area of the base 1 where the air inlet of the fog cannon 2 is located and the tail area where the pressure nozzle 42 is located are both open. During the working process of the fog cannon 2, a strong wind pressure is generated by the internal fan of the fog cannon 2. According to Newton's third law, the high-speed ejected air flow will generate a reverse thrust on the fog cannon 2 and the base 1, thereby providing assistance for the movement of the base 1. The staff can easily pull the displacement of the base 1 through the handle 13 and control the turning of the base 1, greatly reducing the labor intensity of operating the displacement of the base 1.

[0028] Figure 5The figure shows a cross-sectional view of the tail structure of a fog cannon 2 in a dust removal device for municipal road construction according to an embodiment of the present invention. Figure 5 As shown, in order to increase the air diversion efficiency between the fog cannon 2 and the docking seat 41, an annular airbag 5 is coaxially fixed to the output port of the fog cannon 2, and the airbag 5 is interconnected with multiple air pipes 53. The other end of the air pipe 53 is arranged in the annular area of the outer wall of the fog cannon 2 and is interconnected with the inside of the fog cannon 2. In addition, an annular guide plate 54 is obliquely arranged on the inner wall of the fog cannon 2 in the port area of the air pipe 53, so as to guide the flowing air to the inside of the air pipe 53 and inflate the airbag 5. After the airbag 5 is filled with gas, its bulging range will cover part of the space of the output port of the fog cannon 2, thereby reducing the cross-sectional area of the airflow, significantly increasing the flow rate of the gas flow, indirectly increasing the radiation breadth of the fog, and further increasing the dust reduction and dust removal efficiency of the fog cannon 2.

[0029] When the fog cannon 2 is displaced in the base 1, the inflated airbag 5 will fill the connecting gap between the output port of the fog cannon 2 and the docking seat 41, thereby ensuring the air diversion efficiency, so that the wind pressure generated by the fog cannon 2 is completely diverted by the docking seat 41 to the pressurized nozzle 42, and output to the external environment by the pressurized nozzle 42, thereby reducing the leakage of gas during the circulation process and realizing the rational use of the reverse thrust force generated by the wind pressure.

[0030] Figure 6 FIG. 5 is a cross-sectional schematic diagram of an air bag 5 in a dust removal device for municipal road construction according to an embodiment of the present invention. Figure 6 As shown, the further airbag 5 includes an airtight bag wall 51 and a semi-permeable bag wall 52 interconnected with the airtight bag wall 51, and the semi-permeable bag wall 52 is located on the side of the airtight bag wall 51 away from the port of the fog cannon 2. Among them, the airtight bag wall 51 can be made of polyurethane coated fabric, and the fabric pores can be completely closed by coating PU resin on the surface of nylon, polyester and other base fabrics to achieve high air tightness. The semi-permeable bag wall 52 can be made of warp knitted mesh cloth, and regular pores are formed by a special weaving process, with a pore size of 0.2~1mm, so that after the airbag 5 is inflated, the semi-permeable bag wall 5 limits the gas leakage efficiency and ensures the inflation effect of the airbag 5 after inflation. Due to the structure of the semi-permeable bag wall 52 itself, it will also slow down the leakage of gas and improve the uniformity of gas discharge, so that a ring-shaped limiting layer covered by gas is formed at the output port of the fog cannon 2, thereby improving the uniformity of weapon distribution.

[0031] Figure 7 FIG. 4 is a schematic diagram showing the structure of a pressure nozzle 42 region in a dust removal device for municipal road construction according to an embodiment of the present invention. Figure 7As shown, the pressure nozzle 42 has a flat structure. Its air inlet end is flexibly connected to the end of the docking seat 41 through a hose. And a rotating end connected to the base body 1 is provided at the air inlet end of the pressure nozzle 42. An active rotating mechanism 6 is provided at the end of the pressure nozzle 42. The active rotating mechanism 6 includes an arc-shaped guide rail 61 vertically located on one side of the pressure nozzle 42. An arc-shaped rack 62 is arranged inside the arc. The arc-shaped rack 62 meshes with a first gear 63. A third motor 64 is arranged on one side of the first gear 63. The output shaft of the third motor 64 is coaxially fixed to the first gear 63. And the main body of the third motor 64 is fixed to one side of the pressure nozzle 42. By the forward or reverse rotation of the third motor 64, the first gear 63 and the arc-shaped rack 62 are driven to mesh with each other, thereby driving the deflection of the direction in which the pressure nozzle 42 faces.

[0032] When the pressure nozzle 42 is obliquely oriented towards the ground, after the dust cannon 2 is started, the high-pressure air flow is ejected through the pressure nozzle 42. On the one hand, it can boost the displacement of the base body 1. On the other hand, during the movement of the base body 1, dust blowing operation can be carried out at the end of the base body 1. Especially for the area where leaves fall, the dust blowing efficiency is greatly improved.

[0033] When the pressure nozzle 42 is in a horizontal state, the boosting force converted from the wind pressure acts completely on the base body 1, greatly reducing the labor consumption of the staff for displacement.

[0034] When the pressure nozzle 42 is obliquely upward, a plurality of second atomizing nozzles 421 are arranged through the pressure nozzle 42. And in cooperation with the start of the dust cannon 2, during the displacement of the base body 1, spraying operation can be realized at the tail end.

[0035] Figure 8 The structural schematic diagram of the area of the pressure nozzle 42 in a dust removal device for municipal road construction according to an embodiment of the present invention is shown. Refer to Figure 8 As shown, a liquid supply assembly 7 for supplying liquid to the dust cannon 2 and the pressure nozzle 42 is arranged inside the base body 1. The liquid supply assembly 7 includes a water tank 71 fixed inside the base body 1. A water pump 72 is arranged on one side of the water tank 71. The input end of the water pump 72 is communicated with the inside of the water tank 71. The output end of the water pump 72 is connected to a tee. One path of the tee is connected to a first liquid supply pipe 73. The end of the first liquid supply pipe 73 extends to the first atomizing nozzle at the tail of the dust cannon 2 and is connected to the first atomizing nozzle. And a first electromagnetic valve is arranged on the first liquid supply pipe 73. The other path of the tee is connected to a second liquid supply pipe 74. The end of the second liquid supply pipe 74 extends to the pressure nozzle 42 and is connected to each second atomizing nozzle 421. A second electromagnetic valve is arranged on the second liquid supply pipe 74.

[0036] When the fog cannon machine 2 is stationary for operation, the fog cannon machine 2 can be moved above the base body 1 by the sliding of the fog cannon machine 2 and the support frame 11. The first motor 21 drives the fog cannon machine 2 to rotate to adjust the orientation of the port of the fog cannon machine 2. At this time, the second solenoid valve is closed, the first solenoid valve is opened, and the water pump 72 and the fog cannon machine 2 are started, so that the fog cannon machine 2 sprays fine mist.

[0037] When the dust removal device needs to be moved, the fog cannon machine 2 can be horizontally moved into the base body 1 by the sliding of the fog cannon machine 2 and the support frame 11, and then the orientation of the pressure nozzle 42 is adjusted to cooperate with different working conditions for operation. When spraying operation is to be carried out, the first solenoid valve can be closed and the second solenoid valve can be opened, so that only the wind energy is supplied to the fog cannon machine 2, and water mist is generated at the port of the pressure nozzle 42 to reduce the liquid from flowing back into the flexible connection area between the docking pipe and the pressure nozzle 42.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific situations.

[0039] The above are only the preferred embodiments of this application and are not used to limit this application. For those skilled in the art, various changes and modifications can be made to this application.
