Detailed implementation mode

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] Embodiment 1, please refer to Figures 1 - 9 , including an outer cylinder 100 and a nozzle 200. An inner cylinder 110 is arranged inside the outer cylinder 100, and a nozzle control mechanism 300 is arranged on the inner cylinder 110.

[0043] The nozzle control mechanism 300 includes a support rod 310. The nozzle 200 is arranged on the support rod 310. A water pipe 320 is arranged inside the support rod 310. A sliding seat 330 is slidably arranged inside the inner cylinder 110. A spherical groove 340 is formed on the sliding seat 330. A connecting ball 350 is rotatably arranged inside the spherical groove 340. The support rod 310 is arranged on the connecting ball 350.

[0044] A swinging mechanism 400 is further arranged inside the outer cylinder 100. The swinging mechanism 400 includes a magnetic attraction rod 410 arranged on the support rod 310. A first electromagnet 420 is arranged inside the inner cylinder 110. The first electromagnet 420 is located above the sliding seat 330.

[0045] By applying a pulsed current to the first electromagnet 420 to generate a magnetic force, the sliding seat 330 is reciprocally slid along the inner cylinder 110, and the magnetic attraction rod 410 is reciprocally swung towards the first electromagnet 420, so that the support rod 310 and the nozzle 200 reciprocally swing.

[0046] In this embodiment: This device can be installed during gold mine mining, and is an additional device on a drill rig for land transportation devices, for example, a drill rig installed on a sled or wheels. The inner cylinder 110 is installed in the middle of the outer cylinder 100. A cross-shaped sliding groove is provided on the inner cylinder 110. The sliding seat 330 slides up and down along the cross-shaped sliding groove. A spherical groove 340 is provided in the middle of the sliding seat 330. The connecting ball 350 is rotatably installed in the spherical groove 340, and the support rod 310 is installed on the connecting ball 350. The nozzle 200 is installed at the upper end of the support rod 310, and is connected to a water source by a water pipe 320 to supply water to the nozzle 200.

[0047] A first electromagnet 420 is also installed at the upper part of the inner cylinder 110. The first electromagnet 420 is an annular magnet, and the support rod 310 and the nozzle 200 pass through the middle of the first electromagnet 420. A magnetic attraction rod 410 is installed at the bottom end of the support rod 310, and the magnetic attraction rod 410 has a certain inclination angle. When a periodically changing pulsed current is applied to the first electromagnet 420, a periodically appearing magnetism will be generated at the lower end of the first electromagnet 420 facing the magnetic attraction rod 410.

[0048] There are various choices for the material combination of the sliding seat 330 and the magnetic attraction rod 410. For example, if the sliding seat 330 and the magnetic attraction rod 410 are selected to have magnetic attraction properties, metals that do not have magnetic force themselves can be selected. The rest of the structures of the inner cylinder 110 and the nozzle control mechanism 300 do not have magnetic attraction properties. During the magnetic change process of the first electromagnet 420, when a suction force is generated on the sliding seat 330 and the magnetic attraction rod 410, the sliding seat 330 will drive the connecting ball 350, the support rod 310, and the nozzle 200 to move upward. Since the magnetic attraction rod 410 extends relatively long, the distance of its projection on the horizontal plane from the center of the inner cylinder 110 is greater than that of the first electromagnet 420. Therefore, the magnetic attraction rod 410 will also be attracted by the magnetic pole near the middle position, thereby driving the support rod 310 and the nozzle 200 to swing towards the middle.

[0049] When the magnetic suction force of the first electromagnet 420 on the sliding seat 330 and the magnetic attraction rod 410 disappears, the connecting ball 350, the support rod 310, and the nozzle 200 move downward under the action of inertia, and at the same time, the magnetic attraction rod 410 drives the support rod 310 and the nozzle 200 to swing away from the middle.

[0050] By the periodic alternating change of the magnetism of the first electromagnet 420, the support rod 310 and the nozzle 200 can not only reciprocally swing in the horizontal direction, but also jump in the vertical direction.

[0051] By means of electromagnetic drive, the spray head can perform a combined movement of horizontal swing and vertical swing, increasing the water mist diffusion range and reducing wear compared with mechanical transmission devices.

[0052] In addition, there is a second option where the sliding seat 330 is not magnetic and can be made of plastic like the outer cylinder 100 and the inner cylinder 110. In this case, the magnetic rod 410 can be a non-magnetic metal or the magnetic rod 410 itself is a magnet. When the magnetic rod 410 itself has no magnetism, the same as in the first combination, the sliding seat 330 will be driven up and down by the magnetic rod 410, and the magnetic rod 410 itself also swings horizontally. When the magnetic rod 410 itself is a magnet, it can be selected to pass a periodically alternating pulsed current into the first electromagnet 420, so that the lower end of the first electromagnet 420 facing the magnetic rod 410 generates periodically alternating N-pole / S-pole magnetism. Thus, an alternating suction and repulsion effect is generated on the magnetic rod 410. Similarly, while the magnetic rod 410 drives the support rod 310 and the sliding seat 330 to reciprocate up and down, the magnetic rod 410 itself reciprocates.

[0053] It should be supplemented and explained that the spray head 200 and the first electromagnet 420 are conventional technical means, and their specific structures and working principles will not be elaborated.

[0054] Embodiment 2, this embodiment is an improved description based on Embodiment 1. Specifically, please refer to Figures 2 - 10 , the included angle between the magnetic rod 410 and the support rod 310 is an obtuse angle. There are also two counterweight rods 430 provided on the support rod 310. The magnetic rod 410 and the two counterweight rods 430 are circumferentially equidistantly arranged based on the support rod 310, and the counterweight rods 430 have the same weight as the support rod 310.

[0055] The swing mechanism 400 further includes a plurality of second electromagnets 440 arranged in the outer cylinder 100. The plurality of second electromagnets 440 are circumferentially equidistantly arranged based on the inner cylinder 110.

[0056] By connecting a pulsed current to one of the second electromagnets 440 to generate a magnetic force, the magnetic rod 410 swings reciprocally towards the second electromagnet 440, so that the support rod 310 and the spray head 200 swing reciprocally.

[0057] In this embodiment: Considering the technical pain point that the existing dust suppression equipment also has weak anti-wind disturbance performance, there are often irregular gusts in open-pit mines. The traditional equipment lacks a wind direction linkage mechanism, and the water mist is easily carried away by the airflow and deviated from the target area, resulting in a significant fluctuation in the dust removal efficiency.

[0058] Therefore, a second electromagnet 440 is also installed on the lower side of the first electromagnet 420. The second electromagnet 440 is located between the magnetic attraction rod 410 and the first electromagnet 420. When the wind blows on the outer cylinder 100 in one direction, a pulsed current can be applied to the second electromagnet 440 in the wind direction to generate periodically alternating magnetism. At this time, the sliding seat 330 will be pulled to the middle position due to gravity and magnetic attraction, and the magnetic attraction rod 410 will tilt towards the second electromagnet 440 and swing back and forth at the tilted angle.

[0059] Embodiment 3 is an improved description based on Embodiment 2. Specifically, please refer to Figures 2 - 9 , the nozzle control mechanism 300 further includes a limiting ring 360 and a limiting component 370. The limiting ring 360 is arranged on the connecting ball 350, and the limiting component 370 includes two limiting plates 371 symmetrically arranged on the sliding seat 330.

[0060] A guiding rod 372 is slidably arranged on the sliding seat 330. Two first connecting seats 373 are symmetrically arranged on the guiding rod 372, and second connecting seats 374 are arranged on both of the two limiting plates 371.

[0061] The limiting component 370 further includes two connecting rods 375. One ends of the two connecting rods 375 are movably hinged to the first connecting seats 373 through hinge shafts, and the other ends of the two connecting rods 375 are movably hinged to the second connecting seats 374 through hinge shafts.

[0062] A guiding ball 376 is arranged on the guiding rod 372. A guiding groove 377 is formed on the inner cylinder 110. The guiding rod 372 and the guiding ball 376 are slidably connected in the guiding groove 377, and the distance between the side wall of the guiding groove 377 and the connecting ball 350 gradually decreases from bottom to top.

[0063] In this embodiment: As Figure 3 and Figure 4 shown, the limiting ring 360 installed on the outer circle of the connecting ball 350 plays a limiting role, enabling the connecting ball 350 to rotate in all directions within a certain range. Under the action of gravity, the sliding seat 330 is located at the lowermost side. At this time, since the two counterweight rods 430 have the same weight as the magnetic attraction rod 410, the support rod 310 and the nozzle 200 also try to keep vertical.

[0064] When the sliding seat 330 is located at the lowermost side, the limiting ring 360 is clamped by the upper and lower two limiting components 370. At this time, the support rod 310 and the nozzle 200 cannot swing, but can rotate in place. Therefore, when the second electromagnet 440 located between the magnetic attraction rod 410 and the first electromagnet 420 generates a suction force, during the process of the support rod 310 and the nozzle 200 rising along with the sliding seat 330, the magnetic attraction rod 410 will rotate to the position of the second electromagnet 440 that generates magnetic suction force. The specific height of the second electromagnet 440 is flush with the upper vertical section in the guide groove 377.

[0065] During the upward movement of the sliding seat 330, first, the two guide balls 376 slide on the lower vertical sections of the two guide grooves 377, and the two limiting plates 371 keep clamping the limiting ring 360. When the two guide balls 376 slide to the inclined sections of the two guide grooves 377 and finally reach the upper vertical sections, the two guide balls 376 drive the two guide rods 372 to move in the direction of approaching each other inward. At this time, through the transmission of the four connecting rods 375, the two limiting plates 371 move away from each other in the up and down directions respectively, releasing the limiting ring 360, and the support rod 310 and the water pipe 320 can swing.

[0066] When the sliding seat 330 moves to the upper side and then falls, the limiting ring 360 is restricted by the two limiting plates 371 that gradually approach, the swing amplitude gradually decreases, and finally stops swinging.

[0067] Finally, it makes the swing amplitude of the support rod 310 and the nozzle gradually increase during the rising process and gradually decrease during the falling process, and the water mist trajectory forms a spiral rising space envelope surface, improving the dust capture rate.

[0068] Embodiment 4 is an improved description based on Embodiment 3. Specifically, please refer to Figures 2 - 11 , a power supply mechanism 500 is further arranged inside the outer cylinder 100. The power supply mechanism 500 includes a circuit board 510 and a first power connection board 520 arranged inside the outer cylinder 100.

[0070] A plurality of second power connection boards 550 are circumferentially arranged inside the outer cylinder 100. The plurality of second power connection boards 550 respectively correspond to the plurality of second electromagnets 440 one by one. The positive pole of the second electromagnet 440 is connected to the circuit board 510 through a third wire 560, and the negative pole of the second electromagnet 440 is connected to the second power connection board 550 through a fourth wire 570.

[0071] The power supply mechanism 500 further includes a first power connection component 580. The first power connection component 580 includes a power connection ring 581 disposed on the circuit board 510. A first power connection post 582 is slidably disposed within the outer cylinder 100. The first power connection post 582 is slidably connected within the power connection ring 581, and the first power connection post 582 contacts the first power connection plate 520.

[0072] A shield 120 is disposed on the outer cylinder 100. A plurality of ventilation holes 130 are formed in the outer cylinder 100 and the shield 120, and the plurality of ventilation holes 130 communicate with the inner cavity of the outer cylinder 100.

[0073] The first power connection component 580 further includes a first rotating cylinder 583 rotatably disposed within the outer cylinder 100. A fan blade 584 is disposed on the first rotating cylinder 583.

[0074] The first power connection component 580 further includes two push blocks 585 slidably disposed on the first rotating cylinder 583. The two push blocks 585 are elastically connected to the first rotating cylinder 583 through two springs 586 respectively. A connection cylinder 587 is disposed on the first power connection post 582.

[0075] The power supply mechanism 500 further includes a second power connection component 590. The second power connection component 590 includes a second rotating cylinder 591 rotatably disposed within the outer cylinder 100. A wind vane 592 is disposed on the second rotating cylinder 591. A second power connection post 593 is slidably disposed on the second rotating cylinder 591, and the second power connection post 593 is connected to the first power connection post 582.

[0076] In this embodiment: The circuit board 510 can provide pulsed current through structures such as triodes and connect various wires. The circuit board 510 is a prior art and will not be elaborated. The second power connection post 593 can form a certain angle with the wind vane 592, such as an acute angle.

[0077] First, when there is no wind or the wind force is small, the positive pole of the first electromagnet 420 is connected to the circuit board 510 through the first wire 530. The negative pole of the first electromagnet 420 is sequentially connected to the circuit board 510 through the second wire 540, the first power connection plate 520, the first power connection post 582, the power connection ring 581, and the circuit board 510, and the first electromagnet 420 is energized. At this time, the second power connection post 593 is located below the second power connection plate 550 and does not contact it, and all the second electromagnets 440 are not energized.

[0078] Suppose there is a wind from right to left. Then the wind enters the outer cylinder 100 through the plurality of ventilation holes 130. The wind vane 592 is blown and points to the left. At this time, the second rotating cylinder 591 and the second power connection post 593 rotate together, and the L-shaped second power connection post 593 is located below one of the second power connection plates 550.

[0079] Meanwhile, the fan blade 584 is also rotated by the wind. The fan blade 584 drives the first rotating cylinder 583 to rotate, generating centrifugal force, causing the two push blocks 585 to move outward from the first rotating cylinder 583 against the elastic force of the two springs 586. At this time, the inclined surfaces of the two push blocks 585 fit with the inclined surface of the connecting cylinder 587, pushing the connecting cylinder 587 upward. The connecting cylinder 587 drives the first electrical contact column 582 upward. At this time, the first electrical contact column 582 is separated from the first electrical contact plate 520, and the first electromagnet 420 is de-energized.

[0080] The first electrical contact column 582 still remains in contact with the electrical contact ring 581 when moving upward. The first electrical contact column 582 drives the second electrical contact column 593 upward to contact one of the second electrical contact plates 550. At this time, the positive pole of one of the second electromagnets 440 is connected to the circuit board 510 through the third wire 560, and the negative pole of the second electromagnet 440 is connected to the circuit board 510 through the fourth wire 570, the second electrical contact plate 550, the second electrical contact column 593, the first electrical contact column 582, the electrical contact ring 581. One of the second electromagnets 440 is energized.

[0081] Make the water mist generated by the nozzle 200 form a certain angle with the wind direction, so that most of the water mist can be on the movement path of the dust, thereby enhancing the wind resistance performance.

[0082] After the wind stops or the wind force decreases and is not sufficient to blow the fan blade 584, the two push blocks 585 are reset under the elastic force of the two springs 586, and the connecting cylinder 587 is also reset, causing the second electromagnet 440 to be de-energized and the first electromagnet 420 to be energized.

[0083] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0084] The above is only the preferred embodiment of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
