Description

Technical Field

[0001] This invention relates to the field of dust control technology, specifically to a dust control device for monitoring power construction. Background Technology

[0002] Power construction monitoring refers to monitoring the outdoor environment to determine whether it will affect the installation, maintenance, or upgrade of power facilities. During power engineering construction monitoring, construction sites typically generate a lot of dust, which not only threatens human health but also severely damages the construction environment, necessitating dust control measures at the construction site.

[0003] To address the aforementioned issues, a dust control device for power construction monitoring has been commercially available, comprising a base, a monitoring instrument, a guide tube, a drive assembly and a dustproof tube installed within the guide tube; both the monitoring instrument and the guide tube are mounted on the base; when in use, the monitoring instrument can monitor the environment at the power construction site, and when dust control is required, the drive assembly drives the dustproof tube to slide out of the guide tube, thereby reducing dust in the air and improving environmental comfort and cleanliness.

[0004] The above-mentioned device has the following problems in actual use: When the dustproof pipe is used to reduce dust in the outdoor environment, it can only carry out dust reduction treatment within a fixed distance and range. On the one hand, this results in poor dust reduction effect of the dustproof pipe, and on the other hand, it affects the construction progress of power engineering. In other words, the practicality of the dustproof pipe is poor. Summary of the Invention

[0005] This invention provides a dust control device for power construction monitoring to solve the problem that the effective distance and range of existing dust control equipment and dust control pipes are relatively limited.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a dust prevention device for power construction monitoring, comprising a monitoring box with an open top, a turntable, a monitor, a dust prevention mechanism, and a drive mechanism for rotating the turntable; the turntable is rotatably connected to the monitoring box; the monitor is fixedly connected to the turntable; the dust prevention mechanism includes a water guide cylinder, a dust suppression cylinder, a dust suppression pipe, an annular hollow block, several adjusting blocks equidistantly arranged along the circumferential direction of the dust suppression pipe, a power component for rotating the dust suppression pipe, a motion component for reciprocating the adjusting blocks along the radial direction of the dust suppression pipe, and a water guiding component for guiding water into the water guide cylinder; the water guide cylinder is fixedly connected to the turntable; the dust suppression cylinder is connected to the water guide cylinder; the dust suppression pipe is rotatably connected to the dust suppression cylinder, one end of the dust suppression pipe extends into the water guide cylinder, and the other end of the dust suppression pipe passes through the annular hollow block; the annular hollow block is connected to the free end of the dust suppression cylinder; the adjusting block is slidably connected to the dust suppression pipe.

[0007] The principles and advantages of this scheme are: The drive mechanism rotates the turntable, enabling the monitor to conduct more thorough and comprehensive monitoring of the construction site, thereby improving the monitor's efficiency and quality. Furthermore, the rotation of the turntable expands the effective range of the dust suppression pipe, allowing it to efficiently suppress dust dispersed at the construction site along the circumference of the monitoring box, thus enhancing the dust suppression effect.

[0008] During the circumferential movement of the dust suppression pipe, the pipe can also rotate, which causes the dust suppression liquid sprayed from the pipe to expand its effective range under the action of centrifugal force. This allows the dust suppression liquid to efficiently and completely treat the dispersed dust over a large area, thus further enhancing the dust suppression effect of the dust suppression pipe.

[0009] During the spraying of dust-suppressing liquid from the dust-suppressing pipe, the reciprocating motion of the adjusting block regulates the pipe diameter through which the liquid flows within the pipe, thereby adjusting the pressure of the liquid during spraying and thus the effective range of the dust-suppressing liquid. Therefore, by adjusting the adjusting block, the dust-suppressing liquid can be directed to suppress dispersed dust from near to far and from far to near, ensuring efficient treatment of dust dispersed at greater distances, thus comprehensively improving the efficiency and quality of the dust-suppressing liquid spraying.

[0010] Furthermore, it also includes a diversion component; the diversion component includes a sealing block, a diversion section, and several through holes equidistantly opened on the sealing block along the circumferential direction; the sealing block is fixedly connected to the dust settling pipe, and the sealing block is in contact with the annular hollow block; the diversion section includes a narrow-mouth pipe, a wide-mouth pipe, and an atomizing pipe connected sequentially along the circumferential direction of the annular hollow block; the narrow-mouth pipe, the wide-mouth pipe, and the atomizing pipe are all connected to the annular hollow block; the narrow-mouth pipe, the wide-mouth pipe, and the atomizing pipe are all located on the movement trajectory of the through holes.

[0011] The inclusion of narrow-mouth, wide-mouth, and atomizing tubes is designed to alter the spray pattern of the dust-suppressing liquid, allowing it to flow in three forms: a fine stream, a wide stream, and an atomized state. These variations enrich the ways in which the dust-suppressing liquid disperses dust, ensuring more thorough dust suppression through the application of the liquid in different forms.

[0012] The through-holes are designed to control the flow rate and duration of the dust-suppressing liquid sprayed from the narrow-mouth tube, wide-mouth tube, and atomizing tube. This allows the three flow patterns—narrow, wide, and atomized—to intermittently coordinate with the direct-flow dust-suppressing liquid, thus filling the blind spots in the direct-flow application. Through this process, the flow rate of the dust-suppressing liquid is efficiently distributed, and the blind spots in its application are comprehensively reduced, ensuring that the dust-suppressing liquid can effectively treat the dispersed dust.

[0013] Furthermore, it also includes a drive assembly; the drive assembly includes a drive shaft, a first gear, an annular rack, an outer cylinder with openings on both sides, and a drive unit for driving the drive shaft to rotate; the outer cylinder is fixedly connected to the outer wall of the water guide cylinder; the drive shaft is rotatably connected to the inner wall of the outer cylinder; the first gear is fixedly connected to the drive shaft; the annular rack is fixedly connected to the annular hollow block, and the annular hollow block is rotatably connected to the dust settling cylinder; the first gear meshes with the annular rack; the rotational speed of the sealing block is greater than the rotational speed of the annular hollow block.

[0014] The setting that the rotational speed of the sealing block is greater than that of the annular hollow block is to adjust the points of action of the three flow modes: fine flow, coarse flow, and atomized flow. This allows the three flow modes to expand their effective range through rotation, thereby making the combination of these three flow modes with the direct current flow more efficient. Therefore, by enriching the points of action of the various forms of dust-suppressing liquid, it is ensured that all forms of dust-suppressing liquid can effectively suppress dispersed dust.

[0015] Furthermore, the narrow-mouth tube, the wide-mouth tube, and the atomizing tube are all hinged to the annular hollow block; it also includes an auxiliary part; the auxiliary part includes a guide block, an annular hollow frame, and a power unit for driving the annular hollow frame to perform vertical reciprocating motion; the guide block is fixedly connected to the inner wall of the outer cylinder; the annular hollow frame is slidably connected to the guide block; the outer walls of the narrow-mouth tube, the wide-mouth tube, and the atomizing tube are all in contact with the inner wall of the annular hollow frame.

[0016] The vertical reciprocating motion of the annular hollow frame causes the outlets of the narrow-mouth tube, wide-mouth tube, and atomizing tube to move upwards or downwards. Therefore, under the action of the annular hollow frame, the effective range of the dust-suppressing liquid in the three states of narrow flow, wide flow, and atomization can be further expanded, thus contacting more dispersed dust and ensuring better dust suppression.

[0017] Furthermore, it also includes a linkage unit; the linkage unit includes a side rod and three elastic tubes; the side rod is connected to the inner wall of the outer cylinder; the three elastic tubes are respectively connected to the narrow tube, the wide tube, and the atomizing tube; the side rod is located on the movement trajectory of the elastic tubes.

[0018] The side rods and elastic tubes are designed to compress the dust-suppressing liquid in three states—fine flow, coarse flow, and atomized flow—when it is sprayed out, thereby increasing the force during discharge and enabling the dust-suppressing liquid in these three states to travel a greater distance. In other words, this further enriches the effect of the dust-suppressing liquid in these three states during discharge.

[0019] Furthermore, the linkage also includes a linkage unit; the linkage includes a first cam, a recess, and a first spring; the first cam is fixedly connected to the drive shaft; the recess is fixedly connected to the inner wall of the outer cylinder; the side rod is slidably connected to the recess, and the side rod abuts against the first cam; the two ends of the first spring are respectively connected to the side rod and the recess.

[0020] The vertical reciprocating motion of the side rod can further enhance the squeezing force on the rubber tube and cause the rubber tube to swing. This results in the dust-suppressing liquid being discharged in three states: fine flow, coarse flow, and atomized flow. The effective distance and range are wider, which further improves the efficiency and quality of the rubber tube.

[0021] Furthermore, it also includes a flow guide section symmetrically arranged on both sides of the dust settling pipe; the flow guide section includes a flow guide shaft, a flow guide blade, and a moving part for driving the flow guide shaft to rotate; the flow guide shaft is rotatably connected to the water guide cylinder; the flow guide blade is fixedly connected to the flow guide shaft, and the flow guide blade faces the dust settling cylinder.

[0022] During the rotation of the guide vane, the flow rate of the dust-suppressing liquid into the dust-suppressing cylinder is increased, and the flow rate of the dust-suppressing liquid into the dust-suppressing pipe is accelerated. This ensures that the dust-suppressing liquid can be discharged efficiently and fully through the dust-suppressing pipe, narrow pipe, wide pipe, and atomizing pipe, thereby improving the dust-suppressing efficiency of the dust-suppressing liquid.

[0023] Furthermore, the motion assembly includes several moving parts equidistantly arranged along the circumferential direction of the dust-falling pipe; each moving part includes an arc-shaped block and a second spring; the arc-shaped block is fixedly connected to the adjusting block, and two adjacent arc-shaped blocks are in contact with each other to form a ring; the narrow-mouth pipe, the wide-mouth pipe, and the atomizing pipe all abut against the ring; the two ends of the second spring are respectively connected to the adjusting block and the outer wall of the dust-falling pipe.

[0024] During the oscillation of the narrow-mouth tube, the wide-mouth tube, and the atomizing tube, the arc-shaped block is squeezed, causing the adjusting block to slide into the interior of the dust-suppressing tube, and the second spring is compressed; when the narrow-mouth tube, the wide-mouth tube, and the atomizing tube no longer squeeze the arc-shaped block, the second spring causes the adjusting block to reset, and the arc-shaped block moves synchronously.

[0025] Furthermore, the drive unit is a connecting shaft; both ends of the connecting shaft are fixedly connected to the drive shaft and the drainage shaft, respectively.

[0026] During the rotation of the drainage shaft, the drive shaft is driven to rotate synchronously through the connecting shaft.

[0027] Furthermore, the power unit includes a power shaft, a second gear, a second cam, a push rod, and a third spring; the power shaft is fixedly connected to the inner wall of the outer cylinder; both the second gear and the second cam are fixedly connected to the power shaft; the second gear meshes with the ring rack; the push rod is fixedly connected to the ring hollow frame and abuts against the second cam; the two ends of the third spring are respectively connected to the guide block and the ring hollow frame.

[0028] During the rotation of the ring rack, the ring rack drives the power shaft to rotate via the second gear. During the rotation of the power shaft, the second cam rotates synchronously. During the rotation of the second cam, when the protrusion of the second cam abuts against the stop rod, the stop rod drives the annular hollow frame to move vertically downwards, and the third spring moves accordingly. When the protrusion of the second cam no longer abuts against the stop rod, the third spring moves vertically upwards within the annular hollow frame, and the stop rod moves synchronously. Therefore, the annular hollow frame can perform vertical reciprocating motion. Attached Figure Description

[0047] The drive unit is a connecting shaft; the diversion shaft 29 passes through the water guide tube 4 and extends into the inner sleeve, and the two ends of the connecting shaft are fixedly connected to the drive shaft 19 and the diversion shaft 29 respectively.

[0048] The power unit includes a power shaft 32, a second gear 33, a second cam 34, a push rod 35, and a third spring; the power shaft 32 is fixedly connected to the inner wall of the outer cylinder 22; the second gear 33 and the second cam 34 are both fixedly connected to the power shaft 32; the second gear 33 meshes with the annular rack 21; the push rod 35 is fixedly connected to the annular hollow frame 24 and abuts against the second cam 34; the two ends of the third spring are respectively connected to the guide block 23 and the annular hollow frame 24.

[0049] It also includes a power component; the power component includes a third gear 36 and several water holes equidistantly opened on the third gear 36 along the circumferential direction; the third gear 36 is fixedly connected to the sealing block 15; the water holes communicate with the through holes; the power component includes a fourth gear 39 and a side hole opened on the dust collection cylinder 5; the fourth gear 39 is fixedly connected to the diversion shaft 29; the third gear 36 can rotate in the side hole, and the third gear 36 meshes with the fourth gear 39.

[0050] Specific implementation process: During the monitoring of the construction site by the monitor 3, the turntable 2 is rotated by the second motor, enabling the monitor 3 to conduct more thorough and comprehensive monitoring of the construction site, thereby improving the monitoring efficiency and quality of the monitor 3. Furthermore, during the rotation of the turntable 2, the water pump guides the dust-suppressing liquid in the water tank 13 along the water guide pipe 12 into the water guide cylinder 4, allowing the dust-suppressing pipe 37 to efficiently suppress the dust dispersed at the construction site along the circumferential direction of the monitoring box 1, thus expanding the effective range of the dust-suppressing pipe 37 and enhancing its dust-suppressing effect.

[0051] During the discharge of dust-suppressing liquid from the dust-suppressing pipe 37, the second motor is started, driving the rotating shaft 8 to rotate via its output shaft. During the rotation of the rotating shaft 8, the meshing of the first bevel gear 9 and the second bevel gear 10 further drives the dust-suppressing pipe 37 to rotate. Therefore, during the circumferential movement of the dust-suppressing pipe 37, it can also rotate on its own axis, causing the dust-suppressing liquid sprayed from the pipe 37 to expand its effective range under centrifugal force. This allows the dust-suppressing liquid to efficiently and completely treat a large area of ​​dispersed dust, further enhancing the dust-suppressing effect of the dust-suppressing pipe 37.

[0052] During the rotation of the dust collection pipe 37, the dust collection pipe 37 drives the fourth gear 39 to rotate via the third gear 36. During the rotation of the fourth gear 39, the diversion shaft 29 rotates synchronously. During the rotation of the diversion shaft 29, the diversion shaft 29 drives the drive shaft 19 to rotate synchronously via the connecting shaft. During the rotation of the drive shaft 19, the drive shaft 19 drives the ring rack 21 to rotate synchronously via the first gear 20. During the rotation of the ring rack 21, since the second gear 33 meshes with the ring rack 21, the second gear 33 drives the power shaft 32 to rotate. During the rotation of the power shaft 32, the second cam 34 rotates synchronously.

[0053] During the rotation of the second cam 34, when the protrusion of the second cam 34 abuts against the abutment rod 35, the abutment rod 35 drives the annular hollow frame 24 to move vertically downward, and the third spring is compressed; when the protrusion of the second cam 34 no longer abuts against the abutment rod 35, the third spring moves vertically upward in the annular hollow frame 24, and the abutment rod 35 moves synchronously. Therefore, the annular hollow frame 24 can perform vertical reciprocating motion.

[0054] Through the vertical reciprocating motion of the annular hollow frame 24, the narrow tube 16, the wide tube 17, and the atomizing tube 18 can open downwards when above the dust settling tube 37 and open upwards when below the dust settling tube 37, that is, the narrow tube 16, the wide tube 17, and the atomizing tube 18 can swing up and down.

[0055] During the oscillation of the narrow tube 16, the wide tube 17, and the atomizing tube 18, the arc-shaped block 31 is squeezed, causing the adjusting block 7 to slide into the dust-falling tube 37, and the second spring is compressed; when the narrow tube 16, the wide tube 17, and the atomizing tube 18 no longer squeeze the arc-shaped block 31, the second spring drives the adjusting block 7 to reset, and the arc-shaped block 31 moves synchronously.

[0056] During the spraying of dust-suppressing liquid from the dust-suppressing pipe 37, the reciprocating motion of the adjusting block 7 can adjust the diameter of the pipe through which the dust-suppressing liquid flows within the pipe 37, thereby adjusting the pressure of the dust-suppressing liquid during spraying, and thus adjusting the effective distance of the dust-suppressing liquid. Therefore, by adjusting the adjusting block 7, the dust-suppressing liquid can be directed to suppress dispersed dust from near to far and from far to near, thus enabling efficient treatment of dust dispersed at greater distances, thereby comprehensively improving the efficiency and quality of the dust-suppressing liquid spraying.

[0057] The narrow-mouth tube 16, the wide-mouth tube 17, and the atomizing tube 18 are designed to change the spray pattern of the dust-suppressing liquid, allowing it to form three states: a fine flow, a wide flow, and an atomized state. By varying these three states, the way the dust-suppressing liquid acts on the dispersed dust during spraying is enriched, ensuring that the dispersed dust is more effectively suppressed under the action of the various forms of dust-suppressing liquid.

[0058] The through-holes are designed to control the flow rate and duration of the dust-suppressing liquid ejected from the narrow-mouth tube 16, the wide-mouth tube 17, and the atomizing tube 18. This allows the three flow modes—thin, wide, and atomized—to intermittently coordinate with the direct current ejected from the dust-suppressing tube 37, thereby filling the blind spots in the direct current's effect. Through this process, the flow rate of the dust-suppressing liquid is efficiently distributed, and the blind spots in its effect are comprehensively reduced, ensuring that the dust-suppressing liquid can fully treat the dispersed dust.

[0059] The setting that the rotational speed of sealing block 15 is greater than that of the annular hollow block 6 is to adjust the points of action of the three flow modes: fine flow, coarse flow, and atomized flow. This allows the three flow modes to expand their effective range through rotation, thereby making the combination of these three flow modes with the direct current flow more efficient. Therefore, by enriching the points of action of the various forms of dust-suppressing liquid, it is ensured that all forms of dust-suppressing liquid can effectively suppress dispersed dust.

[0060] Because the outlets of the narrow tube 16, the wide tube 17, and the atomizing tube 18 can be tilted upwards or downwards under the influence of the annular hollow frame 24, the effective range of the dust-suppressing liquid in the three states of fine flow, wide flow, and atomization can be further expanded under the action of the annular hollow frame 24, thereby contacting more dispersed dust and ensuring a better dust suppression effect.

[0061] The side rod 25 and the elastic tube 26 are designed to compress the dust-suppressing liquid in the three states of fine flow, coarse flow, and atomized state when it is sprayed out, thereby increasing the force when it is discharged and enabling the dust-suppressing liquid in the three states of fine flow, coarse flow, and atomized state to act further, thus further enriching the effect of the dust-suppressing liquid in the three states of fine flow, coarse flow, and atomized state when discharged.

[0062] During the rotation of the drive shaft 19, the first cam 27 rotates synchronously. During the rotation of the first cam 27, when the protrusion of the first cam 27 abuts against the side rod 25, the side rod 25 moves vertically upward, and the first spring is compressed; when the protrusion of the first cam 27 no longer abuts against the side rod 25, the side rod 25 returns to its original position under the action of the first spring, and the side rod 25 moves vertically downward. Therefore, the side rod 25 can perform vertical reciprocating motion.

[0063] The vertical reciprocating motion of the side rod 25 can further enhance the squeezing force on the rubber tube and cause the rubber tube to swing. This results in the dust-suppressing liquid in three states—fine flow, coarse flow, and atomized flow—being discharged with a longer operating distance and a wider operating range, thus further improving the efficiency and quality of the rubber tube.

[0064] During the rotation of the guide shaft 29, the guide vanes 30 rotate synchronously. During the rotation of the guide vanes 30, the flow rate of the dust-suppressing liquid into the dust-suppressing cylinder 5 is increased, and the flow velocity of the dust-suppressing liquid into the dust-suppressing pipe 37 is accelerated. This ensures that the dust-suppressing liquid can be discharged efficiently and fully through the dust-suppressing pipe 37, the narrow-mouth pipe 16, the wide-mouth pipe 17, and the atomizing pipe 18, thereby improving the dust-suppressing efficiency of the dust-suppressing liquid.

[0065] In summary, this method can increase the effective distance and range of the dust-suppressing liquid, and enrich the various forms of the dust-suppressing liquid when discharged. This enables the dust-suppressing liquid to effectively and thoroughly suppress dust dispersed at the power construction site. On the one hand, it improves the monitoring quality of the monitor 3, and on the other hand, it reduces the harm of dispersed dust to the power construction site.

[0066] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
