[0036] By setting up a detachable design of the box body 21 and the sealing cover 22 of the liquid box 20, the filling, draining, cleaning and maintenance of the liquid box 20 are facilitated. At the same time, the sealing cover 22 can ensure that the dust reduction liquid in the liquid cavity will not leak due to bumps during transportation or work, thereby enhancing the practicality of the device; by opening the liquid port 211, the dust reduction liquid can be more conveniently added and discharged, thereby improving the efficiency and convenience of the equipment.

[0037] Specifically, there are multiple liquid ports 211 and multiple sealing covers 22, and the multiple sealing covers 22 correspond one-to-one to the multiple liquid ports 211; one of the liquid ports 211 is set above the box body 21 for adding dust reduction liquid; the other liquid port 211 is set at the bottom of the box body 21 for discharging dust reduction liquid.

[0038] Through the design of multiple liquid ports 211 and sealing covers 22, the filling and discharge of dust reduction liquid can be carried out simultaneously, thereby improving work efficiency; the upper liquid port 211 is used for filling dust reduction liquid, while the lower liquid port 211 is used for discharge. This design not only simplifies liquid management, but also facilitates the timely discharge of liquid during the transfer of equipment, making it more convenient for the transfer of the entire device.

[0039] like Figure 1 and Figure 2 As shown, the spray dust removal device also includes a protective box 70, which is detachably mounted on the movable frame 10; the protective box 70 has a protective cavity 71 inside, and the liquid-driven pump 30 is disposed in the protective cavity 71; the lifting assembly 50 is detachably disposed on the upper portion of the protective box 70; the control assembly 40 includes a control panel 41, which has operating buttons, and the control panel 41 is disposed on the protective box 70 and outside the protective cavity 71.

[0040] The design of the protective box 70 and the protective chamber 71 provides physical protection for the liquid-driven pump 30, prevents it from being damaged by external collisions or harsh environments, and enhances the durability of the equipment; by arranging the control panel 41 outside the protective chamber 71, it is more convenient for staff to operate and monitor, while avoiding the potential risk of direct contact between electrical equipment and dust-reducing liquid.

[0041] like Figure 1 and Figure 2 As shown, the spray dust removal device further includes a closing plate 80, and the protection box 70 further has an operating port, which is connected to the protection cavity 71; the closing plate 80 is detachably provided on the protection box 70 for opening and closing the operating port.

At the same time, in the closed state, it can protect the internal electrical components from the influence of the external environment, ensuring the long-term stable operation of the electrical equipment.

[0043] like Figure 1 and Figure 3 As shown, the spray assembly 60 includes: a protective shell 61, a drive motor 62, a rotating fan blade 63 and at least one high-pressure nozzle 64; the protective shell 61 is fixedly arranged on the lifting assembly 50, the drive motor 62 is fixedly arranged in the protective shell 61, the rotating fan blade 63 is driven and connected to the drive motor 62, and the drive motor 62 is used to drive the rotating fan blade 63 to rotate; the high-pressure nozzle 64 is connected to the liquid drive pump 30 through a pipeline for spraying dust reduction; wherein, the spray direction of the high-pressure nozzle 64 is vertically upward or has an angle with the vertical direction, and the rotation axis of the rotating fan blade 63 is vertically arranged so that the wind flow blown out by the rotating fan blade 63 moves vertically upward; the high-pressure nozzle 64 is arranged below the rotating fan blade 63 so that the rotating fan blade 63 stirs the dust reduction liquid sprayed by the high-pressure nozzle 64.

[0044] The protective shell 61 design of the spray assembly 60 provides protection for the drive motor 62 and the rotating fan blades 63, reduces the direct intrusion of external dust and liquid, and improves the life of the assembly; the coordinated work of the high-pressure nozzle 64 and the rotating fan blades 63 not only increases the spray coverage area, but also uses the wind flow to stir the liquid, thereby improving the atomization and dust reduction effect.

[0045] like Figure 1 and Figure 2 As shown, the lifting assembly 50 includes an electric lifting column, which is electrically connected to the control assembly 40. The spray assembly 60 is arranged at the upper end of the electric lifting column to follow the lifting and lowering of the upper end of the electric lifting column; wherein, the spray assembly 60 is connected to the liquid drive pump 30 through a hose 100; the length of the hose 100 is retractable and / or has a redundant length design.

[0046] The electric lifting column, the core of the lifting assembly 50, is electrically connected to the control assembly 40, enabling precise adjustment of the spray height and improving dust removal efficiency. The retractable and redundant design of the hose 100 ensures continuous and stable liquid delivery during the lifting of the spray assembly 60, preventing interruptions in liquid supply due to height changes.

[0047] like Figure 1As shown, the spray dust removal device also includes at least two handles 90, which are respectively fixed at both ends of the mobile frame 10 for holding; the mobile frame 10 adopts a stretcher structure, and the liquid tank 20 is arranged in the middle of the mobile frame 10; the mobile frame 10 also has a fixing hole 11, which is used to fix the mobile frame 10 to an external object by bolting.

[0048] The design of at least two handles 90 makes the transportation of the mobile frame 10 more labor-saving and safer; the setting of the stretcher-type mobile frame 10 and the fixing holes 11 makes it easy to fix the device on different types of external objects, enhances the adaptability and stability of the equipment, and is suitable for a variety of working environments.

[0049] Optionally, the spray dust removal device also includes a battery, which is detachably arranged on the mobile frame 10 and is connected to at least one of the liquid-driven pump 30, the control component 40, the lifting component 50 and the spray component 60 through a circuit to provide electrical energy; and / or, the spray dust removal device also includes a filter, which is detachably arranged on the pipeline connecting the liquid tank 20 and the liquid-driven pump 30, for filtering the dust reduction liquid.

[0050] The detachable battery design is easy to replace and charge, which improves the flexibility and scope of use of the spray dust removal device, especially in environments without a fixed power supply; the setting of the filter can effectively remove impurities in the dust reduction liquid, prevent the clogging of the high-pressure nozzle 64, and ensure the spray effect and continuous operation of the equipment.

[0051] Optionally, the spray dust removal device also includes a liquid level sensor, which is arranged in the liquid tank 20 and is used to detect the liquid level of the dust reduction liquid in the liquid tank 20, and the liquid level sensor is electrically connected to the control component 40; and / or, the spray dust removal device also includes an alarm, which is electrically connected to the control component 40 and is used to emit an alarm sound.

[0053] The specific working process and principle of an embodiment of the present invention are now described in detail as follows:

[0054] When in use, first move the spray dust removal device as a whole to the designated position through the handle 90, then fix the device to an external object (for example, the top beam of the tunnel or the ground) through the fixing hole 11 and the bolt, open the sealing cover 22 of the liquid tank 20, and input water (i.e., dust reduction liquid) into the liquid tank 20 through the liquid port 211. After the liquid tank 20 is full of water, seal the liquid tank 20 through the sealing cover 22, then connect the external power supply or battery, and turn on the liquid drive pump 30 by operating the button on the control panel 41. At this time, the liquid drive pump 30 is driven by the hard The pipe and the hose 100 transfer water from the liquid tank 20 to the high-pressure nozzle 64 connected to the hose 100. The water is converted into water mist by the liquid-driven pump 30 and the high-pressure nozzle 64 and sprayed out. At this time, the driving motor 62 is turned on by the button on the control panel 41. At this time, the driving motor 62 drives the rotating fan blades 63 to rotate. At the same time, the airflow generated stirs the water mist and blows it out of the protective shell 61. Then, according to needs, the lifting component 50 (for example: electric lifting column) is controlled to rise and fall through the buttons on the control panel 41, so that the spray dust removal device can perform spray dust removal at different heights.

[0055] In summary, the present invention provides a spray dust removal device, which realizes spray dust reduction with a simple structure by arranging a movable frame 10, a liquid tank 20, a liquid drive pump 30, a control component 40, a lifting component 50 and a spray component 60 to work together; by arranging the liquid tank 20 to be detachably arranged on the movable frame 10, it is convenient to transport the liquid tank 20 and the movable frame 10 separately, thereby further facilitating the overall movement of the spray dust removal device; by arranging the liquid tank 20 and the control component 40, the lifting component 50, the spray component 60 and the liquid drive pump 30 to be spaced apart, it is effectively avoided that the dust reduction liquid in the liquid tank 20 enters the liquid tank 20 when filling or leaking.
