Description

Technical Field

[0001] The present invention relates to the technical field of dust removal equipment, and particularly to a heatstroke prevention and dust removal sprinkler device for building construction. Background Art

[0002] During the building construction process, especially when carrying out demolition and other work, a large amount of dust is often generated. In order to prevent this dust from flying everywhere, dust removal sprinkler devices are usually equipped at the construction site for spraying. The atomized water sprayed by these devices can not only effectively reduce the surrounding temperature but also effectively eliminate the flying dust in the air, thus improving the construction environment.

[0003] At present, there are already some advanced spraying devices in the market, such as a fog cannon vehicle with a wide spraying range proposed in the publication number CN210874580U. The fog cannon vehicle includes a base, and moving wheels are fixedly connected to the four corners of the bottom of the base, facilitating the flexible movement of the device. A first rolling bearing is fixedly connected to the midpoint of the inner wall bottom of the base, and a support rotating shaft is movably connected to the base through this bearing. The top of the support rotating shaft sequentially penetrates through the first rolling bearing and the base from bottom to top and extends outside the base to be fixedly connected with a support plate for supporting the fog cannon body. At the position on the surface of the support rotating shaft and inside the base, a driven bevel gear is also fixedly connected, and this gear cooperates with a rotating motor fixedly connected to the left side of the base, realizing the horizontal rotation of the fog cannon body through the drive of the motor.

[0004] In addition, during the spraying process of this fog cannon vehicle, an electric push rod is used to drive a rack to move up and down, thereby realizing the up and down deflection of the fog cannon body. This design enables the fog cannon body to perform all-round spraying, greatly improving the spraying efficiency. However, in the actual application process, when it is necessary to sprinkle water and reduce dust in a specific area, although the fog cannon body can be quickly rotated by the motor, under this rapid rotation, the elevation angle of the fog cannon body often cannot change quickly in accordance with the rotation of the motor in time. This results in an insufficient dynamic coverage range of the fog cannon barrel during the rotation of the motor, unable to fully cover the moving area for sprinkling, thus easily causing the problem of omission of the spraying part.

[0005] To solve this problem, some fog cannon vehicles attempt to expand the coverage range by increasing the rotation speed of the motor during design. However, this approach often exacerbates the error of elevation angle control, resulting in uneven spraying and the need for repeated supplementary spraying. This not only wastes water resources but also increases the construction cost and time. Therefore, how to achieve precise control and rapid adjustment of the elevation angle of the fog cannon body while ensuring the spraying efficiency has become an important issue in the current design of fog cannon vehicles. Summary of the Invention

[0006] The present invention proposes a heat-prevention and dust-removal sprinkler device for construction, which has the advantage of dynamic and comprehensive dust reduction coverage, and is used to solve the problem of uneven spraying of current dynamic dust reduction mentioned in the above background technology.

[0007] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: a heatstroke prevention and dust removal sprinkler device for construction, comprising: a box seat, a bogie with a wind tube installed on the surface; a fan blade driven by a motor is arranged inside the wind tube, and an exhaust port is provided at the end of the wind tube, a wind disk located on one side of the exhaust port is movably installed at the end of the wind tube, ventilation holes distributed at equal angles in a circular shape are provided on the surface of the wind disk, and a spray ring frame located outside the ventilation holes is fixedly installed at the end of the wind disk; a reduction gear box is installed on the output shaft of the motor, and the output end of the reduction gear box can drive the wind disk to rotate at a low speed.

[0008] Furthermore, a damping gear is fixedly installed on the top of the box seat, and a damping push rod is movably installed on the outer side of the bogie and is pushed toward the outer side of the damping gear by a tension spring.

[0009] Furthermore, the apertures of the plurality of ventilation holes increase step by step in sequence.

[0010] Furthermore, the end of the air duct is fastened with a water distribution box, and the water distribution box is located above the air outlet.

[0011] Furthermore, a steering outer tooth is fixedly installed on the outer side of the wind disc, and a guide tooth ring coaxially arranged with the bogie is fixedly installed on the surface of the box seat, and the guide tooth ring is engaged with the steering outer tooth.

[0012] Furthermore, a connecting box is fixedly installed on the end of the wind disk shaft, and a driven gear seat is movably installed inside the connecting box. A driving gear seat corresponding to the driven gear seat is fixedly installed on the output end of the reduction gear box, and a connecting push spring is fixedly installed inside the connecting box.

[0013] Furthermore, an electromagnet is fixedly installed on the inside of the connecting box, and a one-way air valve and a damping hole are provided at the end of the connecting box; a power storage gear is fixedly installed on the side of the wind disc shaft, and a power storage gear row meshing with the outer teeth of the power storage gear is movably installed on the inside of the wind tube. The travel switch at the top of the inner side of the wind tube will turn on the electromagnet when the travel switch is turned on.

[0014] Furthermore, a turntable is movably installed on the top of the outer side of the wind tube, and a rope-collecting drum is fixedly installed on the turntable shaft. A pull rope is connected between the rope-collecting drum and the power storage gear row, and a locking bolt is threadedly connected to the surface of the turntable.

[0015] Further, a wind deflector movably installed on the inner side of the air duct is movably installed at the exhaust port, and a stop push frame movably sleeved with the wind deflector is movably installed on the inner side of the air duct.

[0017] The present invention has the following beneficial effects:

[0018] A heatstroke prevention and dust removal sprinkler device for building construction provided by the present invention is innovative in that it ingeniously combines the design of an air duct and adjustable ventilation holes. Multiple ventilation holes are carefully arranged at the end of the air duct of the device, and these ventilation holes have different apertures, aiming to achieve diverse spraying effects through the differential aperture design.

[0019] In actual operation, when it is necessary to sprinkle water and reduce dust in a specific area, the wind disk starts to rotate. As the wind disk rotates, ventilation holes with different apertures will sequentially align with the exhaust port of the air duct. When the pressurized air flow passes through the ventilation holes with different apertures, different spraying distances will be generated. This design ensures that during the rotation of the wind disk, appropriate spraying intensity and coverage range can be provided for different parts of the target area, thereby achieving comprehensive and uniform dust reduction for the entire area.

[0020] Secondly, a steering outer tooth is also ingeniously arranged on the outer side of the wind disk of the device. This design enables the wind disk to deflect a certain angle during one rotation. This deflection ability greatly enhances the flexibility of the wind disk, enabling the device to dynamically adjust the spraying direction when spraying and reducing dust in a large area, ensuring that every corner can be fully covered and the dust reduction effect can be achieved.

[0034] 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 making creative efforts shall fall within the protection scope of the present invention.

[0035] As the first embodiment of this application, please refer to Figure 1It can be seen that the four corners of the bottom of the box seat 1 can be supported and steered by universal wheels. The bogie 2 is movably installed on the surface of the box seat 1 through bearings, so as to facilitate the rotation of the air duct 4 fixed on the bogie 2. In order to provide damping for the rotation of the bogie 2, combined with Figure 5 It can be seen that a damping gear 19 is fixedly installed on the top of the box seat 1, and a damping ejector rod 20 that is movably installed on the outside of the bogie 2 and is pushed against the outer part of the damping gear 19 by a tension spring. Driven by the tension spring, when the bogie 2 rotates on the top of the box seat 1, it has a certain rotational resistance, avoiding unrestricted rotation of the bogie 2.

[0036] Inside the air duct 4, there are fan blades 9 that are driven by a motor 7 and rotate relatively. Generally speaking, the motor 7 is fixed in the middle of the inner cavity of the air duct 4. When the motor 7 drives the fan blades 9 to rotate, it can make the air flow at the left end of the air duct 4 flow towards the right end, and finally be output outward from the air outlet opened at the right end. Moreover, a wind disk 5 is movably installed at the end of the air duct 4 on one side of the air outlet. As Figures 2 - 4 shown, ventilation holes 500 are arranged on the surface of the wind disk 5 in an annular and equally angular distribution. It should be noted that the aperture sizes of the ventilation holes 500 are different. As Figure 3 can be seen, the aperture of the ventilation hole 500 gradually increases in the counterclockwise direction. The output shaft of the motor 7 is installed with a reduction gearbox 8, and the output end of the reduction gearbox 8 can drive the wind disk 5 to rotate at a low speed. This arrangement can ensure that when the fan blades 9 rotate, a relatively stable air flow pressure will be generated inside the air duct 4. When the low-speed rotating wind disk 5 moves the ventilation hole 500 to the air outlet of the air duct 4, due to the difference in aperture size, the length of the air flow ejected outward changes. Combined with the fact that a spray ring frame 6 is fixedly installed at the end of the wind disk 5 outside each ventilation hole 500, when the spray ring frame 6 sprays water outward, combined with the high-speed airflow in the ventilation hole 500, the water is sprayed outward. Due to the different aperture sizes, the distance of the water mist ejected outward also changes relatively. Finally, when the wind disk 5 rotates one week, different-sized apertures all pass through the air outlet of the air duct 4, which can ensure that the area in front of the air duct 4 can be comprehensively covered with water spray, and finally achieve the purpose of dust reduction.

[0037] On this basis, in order to further ensure that the spray ring frame 6 connected to the air outlet can accurately discharge water, from Figure 2 it can be seen that there is a water distribution tank 18 bolted to the end of the air duct 4, and the water distribution tank 18 is located above the air outlet. The shape of the water distribution tank 18 is fan-shaped. When the spray ring frame 6 passes through the water distribution tank 18, it means that the ventilation hole 500 reaches the air outlet. Therefore, the corresponding spray ring frame 6 will also spray water mist outward. The input end of the water distribution tank 18 is generally connected to a water pump. Therefore, the intensity of the spray volume can also be relatively adjusted by the power of the water pump.

[0038] A steering outer tooth 501 is fixedly installed on the outside of the air duct 5. Starting from Figure 3 As can be seen, the number of steering outer teeth 501 is relatively small. Correspondingly, a guiding tooth ring 3 coaxial with the bogie 2 is fixedly installed on the surface of the box seat 1, and the guiding tooth ring 3 meshes with the outer teeth of the steering outer tooth 501. When the motor 7 drives the air duct 5 to rotate slowly for one week, the steering outer tooth 501 will eventually mesh with the guiding tooth ring 3 once. After the front area of the air cylinder 4 is sprayed, by changing the deflection angle of the air cylinder 4, other areas can be sprayed, and finally, full spraying and dust reduction can be achieved.

[0039] During actual operation, the motor 7 drives the fan blade 9 to rotate at a high speed, so that a high-speed air flow is generated in the air cylinder 4. The reduction gearbox 8 is used to drive the air duct 5 to rotate slowly, and the ventilation holes 500 and the corresponding spray ring frame 6 are synchronously passed through the air outlet of the air cylinder 4 and the water distribution tank 18. When the ventilation holes 500 with corresponding apertures pass through the exhaust port, water can be sprayed outwards to achieve the purpose of dust reduction.

[0040] After the air duct 5 rotates one circle, the front area of the air cylinder 4 has also been fully sprayed and dust-reduced. By using the meshing between the steering outer tooth 501 and the guiding tooth ring 3, the air cylinder 4 is deflected by a certain angle, so as to provide water spraying and dust reduction for other areas. Finally, as the air duct 5 rotates continuously, the entire circumference of the box seat 1 can be sprayed and covered.

[0041] Embodiment 2 is a further improvement based on Embodiment 1. Combining Figure 2 、 Figure 6 、 Figure 8 and Figure 9 As can be seen, in order to further disclose the connection method between the air duct 5 and the output shaft of the motor 7, a connection box 12 is fixedly installed at the end of the rotating shaft of the air duct 5, and a driven tooth seat 11 is movably installed inside the connection box 12. The cross-sectional shape of the end of the driven tooth seat 11 is preferably oval, so that not only torque transmission but also relative axial movement can be carried out between the driven tooth seat 11 and the connection box 12. A driving tooth seat 10 corresponding to the driven tooth seat 11 is fixedly installed on the output end of the reduction gearbox 8. When the connection push spring 122 fixedly installed inside the connection box 12 pushes the driven tooth seat 11 towards the driving tooth seat 10, the ends of the driven tooth seat 11 and the driving tooth seat 10 will mesh relatively, so as to ensure that the driving tooth seat 10 can output the rotational force to the driven tooth seat 11, and finally the air duct 5 is driven to rotate slowly through the connection box 12.

[0042] Inside the connection box 12, an electromagnet 22 is fixedly installed. When the electromagnet 22 is energized, it will generate a magnetic force, thereby generating an electromagnetic adsorption force on the driven tooth seat 11, forcing the driven tooth seat 11 to compress the connection push spring 122, and finally causing the meshing between the driven tooth seat 11 and the driving tooth seat 10 to disengage. The rotational force generated by the driving tooth seat 10 cannot be transmitted to the air disc 5 through the driven tooth seat 11 and the connection box 12, and the air disc 5 will also not be able to rotate. Not only that, when the driven tooth seat 11 compresses the connection push spring 122, the air flow inside the connection box 12 will quickly discharge outward from the one-way air valve 121 fixed at its end. After that, when the electromagnet 22 no longer provides magnetic force, the connection push spring 122 will push the driven tooth seat 11 to mesh with the driving tooth seat 10 again. During this process, the air pressure inside the connection box 12 decreases, and the outside air can only slowly enter through the damping holes 120 opened outside the connection box 12, thereby slowing down the movement time of the driven tooth seat 11 towards the driving tooth seat 10.

[0043] On the side of the rotating shaft of the air disc 5, a power storage gear 13 is fixedly installed. Correspondingly, inside the air cylinder 4, a power storage tooth row 14 meshing with the external teeth of the power storage gear 13 is movably installed. Figure 6 It can be clearly seen that the bottom end of the power storage tooth row 14 reciprocates up and down along the inside of the air cylinder 4 by using a piston plate. When the connection box 12 drives the power storage gear 13 to rotate, the power storage tooth row 14 moves upward along the air cylinder 4 until the power storage tooth row 14 touches the travel switch 23 fixed at the top inside the air cylinder 4. When the travel switch 23 is turned on, it will energize the electromagnet 22 and disconnect the connection between the driven tooth seat 11 and the driving tooth seat 10. After that, since the power storage tooth row 14 has a certain gravitational potential energy when moving upward and driving the piston plate, when the power of the driving tooth seat 10 and the driven tooth seat 11 is cut off, the power storage tooth row 14 moves downward under gravity, thereby driving the power storage gear 13 to rotate in the reverse direction. Generally speaking, the upward travel of the power storage tooth row 14 will cause the air cylinder 4 to rotate approximately one week. When the power storage gear 13 rotates in the reverse direction, it can quickly return the air cylinder 4 to the starting position, which avoids the single-direction continuous rotation of the air cylinder 4 and thus avoids the single-direction continuous torsion of the wires and water pipes connected to this device.

[0044] On this basis, in order to accurately control the spraying range of the air cylinder 4, combined with Figure 2 、 Figure 6 and Figure 10It can be clearly seen that a turntable 16 driven to rotate by a handle is movably installed at the outer top of the air duct 4, and a rope winding drum 160 located above the energy storage tooth row 14 is fixedly installed on the rotating shaft of the turntable 16. A pull rope 15 is connected between the rope winding drum 160 and the energy storage tooth row 14. By rotating the turntable 16, the rope winding drum 160 will wind the pull rope 15, thereby restricting the downward position of the energy storage tooth row 14. When the energy storage gear 13 drives the energy storage tooth row 14 to rotate upward, since the upward movement stroke of the energy storage tooth row 14 is shortened, the height between the energy storage tooth row 14 and the travel switch 23 is also shortened, and the actual deflection angle of the air duct 4 will also be shortened, that is, the actual deflection range of the air duct 4 is controlled. In terms of limiting, a locking bolt 161 is threadedly connected to the surface of the turntable 16. When the locking bolt 161 is tightened on the turntable 16, it will fasten the side of the air duct 4, thereby restricting the rotation of the turntable 16, and further stably restricting the rotation of the rope winding drum 160.

[0045] Moreover, combined with Figures 6 - 8 it can be seen that a wind deflector 17 movably installed at the exhaust port is movably installed inside the air duct 4. The overall shape of the wind deflector 17 is in an "L" shape. And, a stop push frame 21 movably sleeved with the wind deflector 17 is movably installed inside the air duct 4, and a buffer spring 211 is arranged inside the stop push frame 21. One end of the buffer spring 211 is fixed inside the stop push frame 21, and the other end is in a free state, ensuring that when the wind deflector 17 is away from the buffer spring 211, the wind deflector 17 will not elastically stretch the buffer spring 211. A hook claw 210 is fixedly installed at the end of the stop push frame 21. Correspondingly, a check outer tooth 140 located near the lower part is fixedly installed on the side of the energy storage tooth row 14. The cross-sectional shape of the check outer tooth 140 is a right triangle. When the hook claw 210 passes through the inclined surface of the check outer tooth 140, the ball head at the top of the hook claw 210 will abut against the arc groove at the bottom of the check outer tooth 140, thereby increasing the separation resistance between the hook claw 210 and the check outer tooth 140. And, a locking outer tooth 141 is fixedly installed on the side of the energy storage tooth row 14 and at the bottom of the check outer tooth 140. When the locking outer tooth 141 abuts against the hook claw 210 and continuously moves upward, it will push the wind deflector 17 outward by the stop push frame 21, and after the wind deflector 17 passes over the exhaust port, it can be stably pressed on the end of the wind disk 5. From Figure 6 and Figure 8 it can be seen that an outer ring sleeve 110 is movably sleeved outside the driven tooth seat 11, and the outer ring sleeve 110 and the wind deflector 17 are fixedly connected by a guide rod. When the driven tooth seat 11 axially moves, it will synchronously drive the wind deflector 17 to axially move, ensuring that the wind deflector 17 and the outer ring sleeve 110 can axially move synchronously.

[0046] During the actual operation of the second embodiment, the motor 7 causes the fan blade 9 to rotate rapidly, so that the external air flow passes through the inside of the air duct 4 and is quickly ejected outward from the exhaust port. The air flow finally shoots out through the ventilation holes 500 and sprays the water mist sprayed from the corresponding spray ring frame 6 forward. During the rotation of the motor 7, after the output end of the reduction gearbox 8 is transmitted through the driving tooth seat 10, the driven tooth seat 11 and the connection box 12, the air disk 5 rotates slowly. The slowly rotating air disk 5 enables a plurality of ventilation holes 500 to communicate with the exhaust port in sequence, so as to achieve comprehensive spraying in the front area of the air duct 4. At the same time, while the air disk 5 drives the energy storage gear 13 to rotate slowly, it will drive the energy storage tooth row 14 to move upward, and finally cause the energy storage tooth row 14 to relatively approach the travel switch 23.

[0047] When the air disk 5 rotates one week, the outer steering external teeth 501 thereof will engage with the guiding tooth ring 3. By using the engagement of the steering external teeth 501 and the guiding tooth ring 3, the air disk 5 is forced to drive the air duct 4 to deflect by a certain angle. After that, after a plurality of ventilation holes 500 pass through the exhaust port in sequence, the spray ring frame 6 can comprehensively sprinkle water and remove dust in the rotated area. As the air duct 4 rotates nearly one circle, the energy storage tooth row 14 moves upward and approaches the travel switch 23. At the same time, the upward check external teeth 140 will pass through the claw 210. When the inclined surface of the check external teeth 140 passes through the claw 210, the buffer spring 211 can be compressed by using the stop push frame 21 and the wind shield 17. After the claw 210 crosses the check external teeth 140, the claw 210 is pushed by the elastic force of the buffer spring 211 to abut against the upper part of the next check external teeth 140 again. When the travel switch 23 is pressed, the electromagnet 22 will be turned on and generate magnetism. The magnetism attracts the driven tooth seat 11 and compresses the connecting push spring 122. At the same time, the driven tooth seat 11 also quickly discharges the air flow inside the connection box 12 from the one-way air valve 121. At this time, the power transmission between the driving tooth seat 10 and the driven tooth seat 11 is cut off. Moreover, during the process of the driven tooth seat 11 compressing the connecting push spring 122, the wind shield 17 also moves relatively away from the stop push frame 21 synchronously. When the wind shield 17 completely blocks the exhaust port, the wind shield 17 will drag the stop push frame 21 to forcibly separate the claw 210 and the check external teeth 140. After that, since the energy storage tooth row 14 is no longer restricted, when the self-weight of the energy storage tooth row 14 and the air flow pressure inside the air duct 4 act on the piston plate at the bottom of the energy storage tooth row 14, the energy storage tooth row 14 will quickly move downward and reset. When the travel switch 23 is released from being pressed, the electromagnet 22 will also stop working. The driven tooth seat 11 is pushed by the elastic force of the connecting push spring 122 to relatively approach the driving tooth seat 10. Since only air is slowly injected into the connection box 12 through the damping hole 120 during the movement of the driven tooth seat 11, the driven tooth seat 11 slowly approaches the driving tooth seat 10, ensuring that the energy storage tooth row 14 has enough downward space. Moreover, when the driven tooth seat 11 no longer provides power, it is also convenient to apply a reverse driving force to the air disk 5.

[0048] During the downward movement of the energy storage tooth row 14, the engagement with the energy storage gear 13 forces the wind disk 5 to rotate in the reverse direction. When the outer turning teeth 501 pass by the guide tooth ring 3 again, the wind cylinder 4 will deflect in the reverse direction and finally return to the starting position. Regarding the limitation of the starting position, the winding drum 160 can wind the pulling rope 15 to control the actual downward height of the energy storage tooth row 14, thereby controlling the actual spraying range of the wind cylinder 4.

[0049] Finally, when spraying at a fixed position is required, in the shutdown state, by rotating the wind disk 5 to connect the corresponding ventilation holes 500 with the exhaust port, the turntable 16 winds the pulling rope 15 through the winding drum 160, causing the energy storage tooth row 14 to continuously move upward. Eventually, when the locking outer teeth 141 pass by the claw 210, the inclined surface of the locking outer teeth 141 pushes the claw 210 and the stop push frame 21 closer to the wind disk 5, forcing the windshield 17 to tightly press against the end of the wind disk 5 after passing over the exhaust port, thereby restricting the rotation of the wind disk 5. Moreover, when the windshield 17 moves towards the wind disk 5, the outer ring sleeve 110 drags the driven tooth seat 11 to move synchronously, and cuts off the power between the driven tooth seat 11 and the driving tooth seat 10. When the motor 7 is restarted, since the wind disk 5 is locked and there is no power source, it will work with a fixed spraying range.
