[0063] Existing dust removal equipment usually has a simple structure. There is usually only one fan installed inside the fog cannon, and the shape of the cross-section of the fog cannon's air outlet is usually set to be circular. The circular opening of a single fan has a small coverage area per unit time, and the fog-making efficiency is low. This will make the dust removal range of the dust removal equipment smaller. Moreover, since the wind energy provided by a single fan is small, the fog cannon cannot spray water mist over a long distance, resulting in a small dust removal range and low dust removal efficiency.

[0064] The embodiment of the utility model solves the technical problems of low fog-making efficiency and small dust removal range of the fog cannon in the prior art by providing a fog cannon and a dust removal device, thereby improving the fog-making efficiency of the fog cannon and expanding the dust removal range.

[0065] The technical solution in the embodiment of the utility model is to solve the technical problems of low fogging efficiency and small dust removal range of the fog cannon in the above-mentioned prior art. The overall idea is as follows:

[0066] The fan is rotatably arranged inside the shell and between the air inlet and the air outlet so that the shell can gather the wind force of the fan. The atomizing nozzle is arranged on the inner side of the air outlet, so that the atomized particles sprayed by the atomizing nozzle can be carried to the target area by the wind force generated by the fan, and the dust and harmful gases in the target area can be removed. The number of fans is set to multiple, and the multiple fans are arranged at intervals along the second direction, and the first direction is perpendicular to the second direction. This can make the amount of fog generated per unit time larger, thereby improving the fogging efficiency. In addition, since multiple fans can provide more powerful wind energy, the spray range of the atomized particles is expanded.

[0067] In order to better understand the above technical solution, the above technical solution will be described in more detail below in conjunction with the accompanying drawings and specific implementation methods.

[0068] Please also read Figures 1 to 4 , Figure 1 It is a structural schematic diagram of the fog cannon 10 and the dust removal device 1 in the lifted state provided by the embodiment of the utility model; Figure 2 It is a structural schematic diagram of a fog cannon 10 provided in an embodiment of the utility model; Figure 3 It is a partial enlarged view of the fog cannon 10 and the dust removal device 1 provided in the embodiment of the utility model; Figure 4 yes Figure 3 Side view of.

[0069] In this embodiment, the fog cannon 10 includes a shell 101, a fan 102 and an atomizing nozzle 103. The shell 101 has an air inlet end 101b and an air outlet end 101a, and the air inlet end 101b and the air outlet end 101a are arranged relatively to each other in a first direction; the fan 102 is rotatably arranged inside the shell 101, and the fan 102 is located between the air inlet end 101b and the air outlet end 101a; the atomizing nozzle 103 is arranged on the inner side of the air outlet end 101a; wherein, there are multiple fans 102, and the multiple fans 102 are arranged at intervals along the second direction, and the first direction is perpendicular to the second direction. When the fog cannon 10 is in operation, the fan 102 rotates and air is sucked in through the air inlet end 101b. When the fan 102 starts to rotate, the fan 102 will cut and push the surrounding air. The air molecules are impacted and pushed by the surface of the fan 102, thereby changing the speed and direction of the air, thereby generating wind force, and the outer shell 101 has a convergence effect on the wind force, thereby generating strong wind force at the air outlet end 101a. At the same time, the fog cannon 10 converts water into atomized particles for spraying through the atomizing nozzle 103 arranged on the inner side of the air outlet end 101a, that is, the wind force at the air outlet end 101a and the atomized particles sprayed by the atomizing nozzle 103 act synchronously, so that the atomized particles can be sprayed to the target area, and the target area is dusted and harmful gases are absorbed, creating a good construction environment.

[0070] In some embodiments of the present application, the multiple fans 102 are arranged at intervals in the horizontal direction, that is, the multiple fans 102 are arranged horizontally.

[0071] The shell 101 is configured to have an air inlet end 101b and an air outlet end 101a, and the air inlet end 101b and the air outlet end 101a are arranged relatively to each other in a first direction. On the one hand, the shell 101 is configured to have the air inlet end 101b and the air outlet end 101a, so that the shell 101 can effectively inhale external air through the air inlet end 101b, and then smoothly discharge the internal air through the air outlet end 101a, thereby ensuring that the structure of the shell 101 can perform air convection exchange.

[0072] By arranging the fan 102 between the air inlet end 101b and the air outlet end 101a, the inhaled cold air can be directly accelerated and pushed, making the air flow faster and more efficient. This layout helps to reduce the resistance of the air inside the fan and improve the heat dissipation efficiency of the heat dissipation fan. When the fan 102 rotates, it will quickly inhale the cold air and push it to the air outlet end 101a by accelerating, forming an effective air convection. This convection can quickly take away the heat inside the device and discharge it to the outside through the air outlet, thereby achieving the purpose of reducing the temperature of the device. In addition, a filter can be set on the air inlet end 101b according to actual conditions to prevent dust and impurities from entering the fan 102, protect the fan 102 and other internal components from damage, and improve the service life of the fog cannon 10. In addition, due to the function of the housing 101 itself, the fan 102 is set between the air inlet end 101b and the air outlet end 101a, which can also achieve the function of reducing the noise generated by the rotation of the fan 102 and enhance the safety of the use of the fog cannon 10.

[0073] The mist cannon 10 is provided with an atomizing nozzle 103, which can quickly atomize water into tiny particles. These atomized particles can quickly cover a large area. Compared with traditional spraying equipment, the atomizing nozzle 103 on the mist cannon 10 can more efficiently utilize water resources, and by forming finer mist particles, increase the area in contact with the air, thereby improving the spray efficiency; the atomizing nozzle 103 on the mist cannon 10 can produce micron-sized atomized particles, which can quickly adsorb and settle dust when in contact with dust, thereby achieving the purpose of purifying the air. According to the working principle of the mist cannon 10, these fine atomized particles can be evenly dispersed in the air, ensuring that the dust particles are effectively adsorbed and settled, thereby optimizing the dust reduction effect, and can also dissolve harmful air in the air and optimize the environment of the target area.

[0074] By arranging the atomizing nozzle 103 on the inner side of the air outlet 101a, the wind force generated by the fan 102 of the fog cannon 10 can be directly used to quickly and evenly blow the atomized particles to the area where dust removal is required, ensuring that the atomized particles can cover a wider area, thereby improving the efficiency of the spray. In some embodiments, a guide plate can also be arranged on the air outlet 101a of the fog cannon 10 so that the wind force generated by the fan 102 can be blown out in a certain direction. When the atomized particles are sprayed out, they can be evenly dispersed, avoiding the aggregation and waste of the atomized particles and optimizing the distribution of the atomized particles.

[0075] By arranging a plurality of fans 102 inside the fog cannon 10, the wind force can be significantly enhanced. On the one hand, the fog cannon 10 can produce a larger amount of fog per unit time, thereby improving the fog-making efficiency of the fog cannon 10. On the other hand, the fog cannon 10 can have a longer range when spraying mist particles. This design enables the fog cannon 10 to cover a wider area and improve the fog-making efficiency. The design of multiple fans 102 can produce stronger airflow, which helps to atomize the liquid into tiny particles more fully, further break up and atomize the droplets, and give the droplets kinetic energy that can penetrate the dust. These tiny atomized droplets can more effectively combine with dust, harmful gases, etc. in the air, thereby improving the effect of cleaning the air and reducing the concentration of particulate matter in the air. Arranging a plurality of fans 102 inside the fog cannon 10 can also form a more stable airflow field, reduce airflow fluctuations and unstable factors, thereby improving the stability and reliability of the operation of the fog cannon 10, so that the fog cannon 10 can still maintain stable performance when it is running for a long time. Since the fog cannon 10 generates a certain amount of heat during operation, the design of multiple fans 102 can accelerate the air flow inside the fog cannon 10, improve the heat dissipation performance, and ensure that the fog cannon 10 can still operate normally in a high temperature environment. The fog cannon 10 is provided with multiple fans 102 inside, and the fog cannon 10 can also be adjusted according to different working environments and needs, so that it can adapt to different wind speeds, thereby expanding the scope of use of the fog cannon 10. Multiple fans 102 are arranged at intervals along the second direction, and the first direction is perpendicular to the second direction. In this way, the wind force generated by the fan 102 can be smoothly ejected from the first direction, thereby driving the atomized particles sprayed out by the atomizing nozzle 103.

[0076] In some embodiments, the shell 101 of the fog cannon 10 can be designed to have a streamlined shape. For example, the shell 101 of the fog cannon 10 can be manufactured to imitate the partial shape of fast-swimming fish such as cutlassfish and sharks. On the one hand, this can facilitate air flow, reduce resistance, and improve spray efficiency; on the other hand, it is more in line with aesthetic requirements and improves the aesthetic quality of product.

[0077] In some embodiments, since the operating environment of the fog cannon 10 is usually in a relatively harsh environment such as a construction site, the shell 101 material needs to have good corrosion resistance and be able to withstand the erosion of chemical substances such as acids and alkalis. In addition, to ensure the service life and durability of the fog cannon 10, the shell 101 material of the fog cannon 10 also needs to have a certain strength and be able to withstand the impact of some external forces to cope with the complex and changeable construction environment.

[0078] Exemplarily, the material of the shell 101 of the fog cannon 10 can be selected from alloy materials with high hardness and strong corrosion resistance, such as stainless steel, fiberglass and aluminum alloy. Stainless steel has excellent corrosion resistance and strength, and is one of the commonly used materials for the shell 101 of the fog cannon 10. The shell 101 made of stainless steel is not only beautiful, but also easy to clean and maintain; fiberglass is a lightweight and high-strength composite material with excellent corrosion resistance and aging resistance. The shell 101 made of fiberglass is not only light, but also wear-resistant and impact-resistant, and is suitable for various harsh environments; aluminum alloy has the advantages of light weight, high strength and good corrosion resistance, and is also one of the commonly used materials for the shell 101 of the fog cannon 10. The shell 101 made of aluminum alloy is not only light and beautiful, but also has good heat dissipation performance, and is suitable for high temperature environments.

[0079] In some embodiments, since the operating environment of the fog cannon 10 is usually in a relatively harsh environment such as a construction site, the fan 102 needs to have good corrosion resistance and be able to withstand the erosion of chemical substances such as acids and alkalis. In addition, to ensure the service life and durability of the fog cannon 10, the fan 102 material of the fog cannon 10 also needs to have a certain strength and be able to withstand the impact of some external forces to cope with the complex and changeable construction environment.

[0080] Exemplarily, the material of the fan 102 of the fog cannon 10 can be set to nylon, glass fiber reinforced plastic, and aluminum alloy. Nylon material has high strength, wear resistance and corrosion resistance, and has good processing performance, and is suitable as the material of the fan 102 in the fog cannon 10; glass fiber reinforced plastic has the advantages of high strength, low weight, corrosion resistance and fatigue resistance, and is suitable for manufacturing large and high-speed rotating fans 102 to improve the performance and reliability of the fan 102. In a large-scale dust removal environment, using a large fog cannon 10 for dust removal, the use of glass fiber reinforced plastic is a better choice; aluminum alloy has the advantages of light weight, high strength and good corrosion resistance, and is also one of the commonly used materials for the fan 102 in the fog cannon 10.

[0081] The size and flow rate of the atomizing nozzle 103 directly determine the atomization effect and coverage. Generally speaking, the larger the diameter of the atomizing nozzle 103, the larger the flow rate, the larger the atomized particles, and the wider the coverage may be; on the contrary, if the diameter of the atomizing nozzle 103 is smaller, the flow rate is smaller, the atomized particles are smaller, and the coverage may be smaller. In some embodiments, different atomizing nozzles 103 can be selected for different scenarios. For example, when the fog cannon 10 needs to be used for short-distance precision spraying, a columnar nozzle can be used; when the fog cannon 10 needs to be used for large-scale spraying, a fan-shaped nozzle can be used.

[0082] In some embodiments, the number of fans 102 may be two or more, and the number of fans 102 may be reasonably applied in different situations.

[0083] Please refer again Figures 2 to 4 In this embodiment, the air outlet 101a has an air outlet, and the cross-sectional area of ​​the air outlet gradually decreases from the air inlet 101b to the air outlet 101a. When the fog cannon 10 is running, the air flows from the air inlet 101b to the air outlet 101a. When the cross-sectional area of ​​the air outlet gradually decreases, according to the Bernoulli equation, when the incompressible fluid described is in a stable flow, for a fluid such as air, when the air outlet area decreases, the static pressure of the fluid will decrease due to the increase in flow rate, and the dynamic pressure (proportional to the square of the flow rate) will increase, so the pressure of the air at the air outlet will increase, so that the atomized particles sprayed by the atomizing nozzle 103 can be broken up, and the particles can be further refined, so that a larger amount of atomized particles can be produced per unit time, and the contact surface area between the particles and dust can be increased, and the dust can be more strongly adsorbed; the contact surface area between the particles and harmful gases can be increased, and the harmful gases can be more fully dissolved. Due to the increase in the flow rate at the air outlet, the atomized particles can reach a longer distance per unit time, so that the spray range of the atomized particles can be expanded and the spray distance can be increased.

[0084] In this embodiment, the fog cannon 10 further includes an annular water pipe 104, which is arranged on the inner side of the air outlet end 101a, and a plurality of atomizing nozzles 103 are evenly and spacedly arranged on the annular water pipe 104. When the fog cannon 10 is in operation, the annular water pipe 104 supplies water to the atomizing nozzles 103, and the atomizing nozzles 103 spray the water in the annular water pipe 104 to the target area. Since multiple atomizing nozzles 103 are evenly and spaced apart on the annular water pipe 104, on the one hand, since multiple atomizing nozzles 103 are independent of each other, single point failure can be avoided. Even if a certain atomizing nozzle 103 fails, water can still be supplied through the annular water pipe 104, thus avoiding the paralysis of the entire water supply system caused by a single point failure; on the other hand, the atomizing nozzles 103 are evenly and spaced apart on the annular water pipe 104, so that the atomized particles sprayed by the atomizing nozzles 103 are more evenly distributed in space, so as to effectively contact the dust and harmful gases in the air, thereby achieving the function of adsorbing dust and dissolving harmful gases, and improving the efficiency and effect of air cleaning. The evenly distributed atomizing nozzles 103 can ensure that the atomized particles form a denser covering layer in the space, thereby more effectively adsorbing dust in the air and causing it to settle quickly, thereby achieving the effect of dust reduction, and can also more effectively dissolve harmful gases in the air, thereby achieving the dissolution effect. Multiple atomizing nozzles 103 are evenly and spaced apart on the annular water pipe 104, which can ensure that the components of the fog cannon 10 are evenly stressed during operation, thereby reducing equipment damage and failures caused by uneven stress. Such a design can also reduce the maintenance cost and frequency of the equipment and improve the service life and stability of the equipment.

[0085] In some embodiments, an air inlet hood 101c is further provided at the air inlet end 101b of the fog cannon 10. On the one hand, the air inlet hood 101c can ventilate and dissipate heat for the fog cannon 10. When the fog cannon 10 is running, a certain amount of heat will be generated inside it. If the heat is not dissipated in time, the performance and life of the fog cannon 10 will be affected. The air inlet hood 101c helps dissipate heat by allowing air to enter the interior of the fog cannon 10, thereby ensuring that the fog cannon 10 can maintain stable performance during continuous operation. On the other hand, the air inlet hood 101c can also prevent external foreign matter, such as dust and sand, from entering the interior of the fog cannon 10, thereby protecting the internal structure of the fog cannon 10, which helps to extend the service life of the fog cannon 10 and reduce the cost of repairing and replacing parts. An air inlet cover 101c is also provided at the air inlet end 101b of the fog cannon 10 to enhance the safety of the use of the fog cannon 10. The air inlet cover 101c can also prevent internal components of the machine from accidentally flying out and injuring people, especially near a high-speed fan. Without the protection of the air inlet cover 101c, components such as the fan 102 may fly out due to failure or external force, causing damage to personnel and equipment. The presence of the air inlet cover 101c greatly reduces this risk.

[0086] In some embodiments, the fan 102 of the fog cannon 10 is connected to the engine, and the fan 102 of the fog cannon 10 is arranged at one end of the engine output shaft. The engine output shaft rotates to drive the fan 102 to rotate. The other end of the engine is fixedly attached to the air inlet cover 101c to accelerate the heat dissipation effect.

[0087] In some embodiments, a fan bracket 102a is also provided inside the fog cannon 10, and the fan bracket 102a fixes the fan 102 on the engine output shaft to ensure stable operation of the fan 102 under high-speed conditions, reduce vibration of the fan 102, and increase the service life of the fog cannon 10.

[0088] See also Figure 1 as well as Figures 3 to 6 , Figure 5 It is a side view of the fog cannon 10 and the dust removal device 1 provided in the embodiment of the utility model in the lifted state; Figure 6 yes Figure 5 Stepped section view of section AA.

[0089] The present embodiment also provides a dust removal device 1, including a mounting platform 11, a fog cannon 10 is rotatably arranged on the mounting platform 11 to adjust the air outlet angle of the air outlet end 101a, and the rotation axis of the fog cannon 10 extends in the horizontal direction. During the operation of the dust removal device 1, the air outlet angle of the air outlet end 101a of the fog cannon 10 is adjusted by rotating the mounting platform 11 in the horizontal direction. In this way, by rotatably arranging the fog cannon 10 on the mounting platform 11 to adjust the air outlet angle of the air outlet end 101a, the flexibility of the dust removal device 1 can be enhanced, so that the spray direction of the dust removal device 1 is no longer fixed, but can be adjusted as needed, so that the dust removal device 1 can cover a wider dust removal area range, especially when dealing with dust sources in different directions, there is no need to move the entire dust removal device 1, and only by rotating the mounting platform 11, the air outlet angle of the air outlet end 101a of the fog cannon 10 can be adjusted.

[0090] For example, the staff remotely controls the direction of the mounting platform 11 through the control system to remove dust from the target area without having to control the rotation of the entire dust removal device 1, which allows the operator to easily and simply operate the dust removal device 1, reducing the difficulty of operation and improving work efficiency. Furthermore, by rotating the mounting platform 11 to adjust the dust removal direction instead of the entire dust removal device 1, energy can be saved and the maximum single use time of the dust removal equipment can be increased.

[0091] The mounting platform 11, as the basic supporting structure of the fog cannon 10, needs to have sufficient stability and load-bearing capacity. In some embodiments, the mounting platform 11 generally includes core components such as a base, a supporting structure, and a rotating component. The fog cannon 10 can be connected to the mounting platform 11 through a base or some specific connectors. Exemplarily, the fixed connection method can be bolt connection, welding, or other fastening methods to ensure that the fog cannon 10 is firmly installed on the mounting platform 11.

[0092] In some embodiments, the rotation of the mounting platform 11 can be achieved by manual control or automatic control, and the automatic control includes remote control, centralized control or intelligent control system, which can automatically adjust the rotation of the mounting platform 11 according to preset programs or environmental parameters. In the rotation mechanism of the mounting platform 11, some safety devices, such as limit switches and overload protection, can also be usually set to prevent accidents or damage to the fog cannon 10 during the rotation process.

[0093] Please refer again Figure 2 , Figure 3 and Figure 4In this embodiment, the mounting platform 11 includes a mounting platform body 111, a first bracket 112 and a second bracket 113, and the first bracket 112 and the second bracket 113 are arranged at intervals on the upper side of the mounting platform body 111; along the spacing direction of the first bracket 112 and the second bracket 113, one end of the housing 101 is rotatably arranged on the first bracket 112, and the other end of the housing 101 has a first driving part 12 and a driving gear 12a connected to the first driving part 12, and the second bracket 113 is provided with an arc-shaped rack 12b matched with the driving gear 12a. The first driving part 12 drives the driving gear 12a connected to the first driving part 12, so that the end of the housing 101 close to the air outlet end 101a can rotate along the arc-shaped rack 12b. When the fog cannon 10 needs to spray upward, the first driving part 12 drives the driving gear 12a connected to the first driving part 12 to rotate, and the driving gear 12a moves upward along the shape of the arc-shaped rack 12b, thereby driving the air outlet end 101a of the fog cannon 10 to be lifted upward in the vertical direction; when the fog cannon 10 needs to spray downward, the first driving part 12 drives the driving gear 12a connected to the first driving part 12 to rotate, and the gear moves downward along the shape of the arc-shaped rack 12b, thereby driving the air outlet end 101a of the fog cannon 10 to rotate downward in the vertical direction. The first bracket 112 is arranged on a side close to the air inlet end 101b of the fog cannon 10, and the housing 101 of the fog cannon 10 is rotatably arranged on the first bracket 112, so that the fog cannon 10 can rotate.

[0094] In some embodiments, the dust removal device 1 also includes a water inlet pipe 106 connected to the annular water pipe 104. When the fog cannon 10 is running, water flows into the annular water pipe 104 through the water inlet pipe 106, and then is converted into atomized particles and sprayed out through the atomizing nozzle 103 arranged on the annular water pipe 104.

[0095] Please refer again Figure 5 and Figure 6 In this embodiment, the dust removal device 1 further includes an upper body 13, and the mounting platform 11 is rotatably disposed on the upper body 13, and the rotation axis of the mounting platform 11 extends in the vertical direction. By rotatably disposing the mounting platform 11 on the upper body 13, the mounting platform 11 drives the fog cannon 10 to rotate, which simplifies the design difficulty of the dust removal device 1, simplifies the structure of the dust removal device 1, reduces the complexity of the dust removal device 1, and makes the dust removal device 1 easier to maintain and repair.

[0096] In some embodiments, a water pump 105 is further provided on the vehicle body 13 of the dust removal device 1 . The water pump 105 presses water into the water inlet pipe 106 , and then inputs the water flow to the atomizing nozzle 103 through the annular water pipe 104 .

[0097] Please refer again Figure 5 and Figure 6In this embodiment, the dust removal device 1 further includes a lower body 14, and the upper body 13 is arranged on the lower body 14, and the height of the upper body 13 relative to the lower body 14 is adjustable. When the dust removal device 1 needs to perform dust removal operations on a space with a higher height, the distance between the upper body 13 and the lower body 14 becomes larger, thereby changing the height of the fog cannon 10, thereby adjusting the dust removal range of the dust removal device 1.

[0098] In some embodiments, the dust removal device 1 also includes a connecting rod mechanism, which includes multiple connecting rods 23, a transmission pin shaft 24, a slide rail arranged on the upper body 13 and the lower body 14, and a slide rail pin shaft 25. The upper body 13 and the lower body 14 are connected through the connecting rod mechanism, one end of the connecting rod mechanism is connected to the slide rail arranged on the upper body 13 through the slide rail pin shaft 25, and the other end of the connecting rod mechanism is connected to the slide rail of the lower body 14 through the slide rail pin shaft 25. By changing the height of the connecting rod mechanism in the vertical direction, the distance between the upper body 13 and the lower body 14 is changed.

[0099] In some embodiments, the dust removing device 1 also includes a hydraulic lifting device 22, which includes a hydraulic cylinder 22a and a hydraulic rod 22b connected to the hydraulic cylinder 22a, one end of the hydraulic rod 22b is connected to the hydraulic cylinder 22a, and the other end of the hydraulic rod 22b is connected to a transmission pin 24 arranged on the connecting rod mechanism. When it is necessary to increase the distance between the upper body 13 and the lower body 14 of the dust removing device 1, the hydraulic cylinder 22a controls the hydraulic rod 22b to extend, and the hydraulic rod 22b becomes longer to support the transmission pin 24, and the transmission pin 24 is subjected to force, thereby acting on the connecting rod 23, thereby increasing the length of the connecting rod mechanism in the vertical direction; when it is necessary to reduce the distance between the upper body 13 and the lower body 14 of the dust removing device 1, the hydraulic cylinder 22a controls the hydraulic rod 22b to shorten, and the hydraulic rod 22b is shortened, the position of the transmission pin 24 changes, and then acts on the connecting rod 23, thereby reducing the length of the connecting rod mechanism in the vertical direction.

[0100] By changing the length of the connecting rod mechanism in the vertical direction through the hydraulic lifting device 22, the fog cannon 10 can be realized, and the fog cannon 10 can be smoothly lifted and lowered. This stability is crucial for the fog cannon 10 because it can reduce the shaking of the fog cannon 10 during the lifting process, thereby maintaining the stability and accuracy of its operation; it can also accurately control the lifting and lowering of the fog cannon 10, and accurately position the fog cannon 10 to a specific position according to actual needs, thereby ensuring the accuracy and effectiveness of the spray effect; and it can bear the weight of a larger fog cannon 10 and its related equipment, because it can ensure the stability and safety of the fog cannon 10 under various conditions. Therefore, the hydraulic lifting device 22 can adapt to different working environments and occasions, and can be customized according to actual needs, expand the use of the dust removal device 1, and improve its flexibility and extensiveness of application.

[0101] See also Figure 1 , Figure 7 and Figure 8 , Figure 7 It is a structural schematic diagram of the fog cannon 10 and the dust removal device 1 provided in the embodiment of the utility model in the unlifted state; Figure 8 It is a bottom view of the upper vehicle body 13 provided in the embodiment of the utility model.

[0102] In this embodiment, the lower body 14 and / or the upper body 13 are provided with an energy storage component 20, and the lower body 14 and / or the upper body 13 are also provided with a charging terminal 21 connected to the energy storage component 20. When the dust removal device 1 is in an unlifted state, the charging terminal 21 provided on the upper body 13 is connected to the charging terminal 21 provided on the lower body 14, and the external power supply transmits power to the dust removal device 1 through the charging interface 27. Through the charging interface 27, the energy storage component 20 provided on the lower body 14 is powered, and the charging terminal 21 of the lower body 14 contacts the charging terminal 21 of the upper body 13, so that the energy storage component 20 of the upper body 13 is also powered, thereby realizing the function of charging the dust removal device 1. In this way, the energy storage component 20 is charged by contacting the charging terminals 21 of the upper body 13 and the lower body 14. On the one hand, it can simplify the design of the internal circuit of the dust removal device 1, reduce the complexity of the design of the dust removal device 1, and save materials and costs; on the other hand, it is also beneficial to the maintenance of the dust removal device 1. When the dust removal device 1 fails, it can facilitate maintenance personnel to quickly repair the fault.

[0103] Exemplarily, the energy storage component 20 can be selected from supercapacitors, lead-acid batteries, lithium-ion batteries and sodium-sulfur batteries. Supercapacitors utilize electrochemical adsorption and removal of charges between electrodes to store and release electrical energy, and have the characteristics of high power density, fast response speed, low energy density and long life; lead-acid batteries are traditional energy storage components with low cost and mature technology; lithium-ion batteries have the advantages of high energy density, long life and good charge and discharge performance; sodium-sulfur batteries have higher energy density and lower cost and are suitable for large-scale energy storage. The dust removal device 1 can select the type of energy storage component 20 according to different types and needs. The utility model does not limit the type of energy storage component 20.

The second driving unit 19 is arranged on the lower body 14 and connected to the wheel 15. The wheel 15 arranged on the lower body 14 is driven by the second driving unit 19, and the second driving unit 19 can control the rotation and direction of the wheel 15, thereby controlling the movement of the dust removal device 1. When it is necessary to control the dust removal device 1 to quickly enter the target area remotely, the rotation of the second driving unit 19 can be accelerated, thereby making the dust removal device 1 move more quickly, thereby traveling a longer distance per unit time, and shortening the time to reach the target area. The second driving unit 19 drives the wheel 15, and can also adjust the dust removal range of the dust removal device 1. When the dust and harmful gases in a target area are processed, the position of the dust removal device 1 is controlled by controlling the rotation of the second driving unit 19, thereby changing the area where the dust removal device 1 is located, and realizing dust removal and harmful gas removal in different areas.

[0105] Exemplarily, the second driving unit 19 can be connected to any two pairs of wheels 15 along the length direction of the dust removal device 1 through a coupling. When the second driving unit 19 rotates, the power is transmitted to the wheel 15 shaft through the coupling, thereby driving the wheel 15 to rotate and providing forward or backward power for the wheel 15. The second driving unit 19 can also be connected to another pair of wheels 15 along the length direction of the dust removal device 1 through a steering structure, thereby adjusting the steering angle of the wheel 15, so that the dust removal device 1 can freely reach the target area to be reached.

The control unit 18 processes the data recorded by the air quality sensor 16 and the camera 17 together, and sends them to the operator, providing strong data support for the operator to control the dust removal device 1. The operator controls the angle and spray intensity of the fog cannon 10 according to the received data, and controls the dust removal device 1 to remove dust and harmful gases.

[0108] The air quality sensor 16 is used to monitor the values ​​of temperature, humidity, air pressure, light, PM2.5, PM10 and TVOC in the air, as well as the concentration of gases such as oxygen, carbon dioxide, carbon monoxide and formaldehyde, and can provide accurate air quality data to help operators better understand the air quality of the construction site environment. Exemplarily, the air quality sensor 16 can be set as an infrared dust particle sensor or a laser dust particle sensor. The infrared dust particle sensor has a built-in infrared light-emitting diode and a high-sensitivity photoelectric receiving sensor, which reflects the concentration of particulate matter in the air by detecting the intensity of reflected light, and then reflects the air quality; the laser dust particle sensor uses laser to irradiate suspended particles in the air to generate light scattering, and the photoelectric detector collects the scattered light intensity within a certain angle range, converts the obtained scattered light intensity linearly into voltage, and then sends it to the data processing system. The data processing system processes the data according to a pre-programmed program to obtain the equivalent particle size of the particles and the number of particles of different particle sizes per unit volume, thereby reflecting the air quality.
