Description

Technical Field

[0001] This invention belongs to the technical field of dust suppression devices, specifically a dust suppression device for processing wind power concrete cement poles. Background Technology

[0002] Concrete poles are an important component of wind power collection lines and tower structures, primarily used to support overhead lines or as foundation components for hybrid towers. Concrete towers are typically curved and sheet-like, generally precast from poured concrete.

[0003] When processing concrete towers, a large amount of cement mortar and aggregate is usually required. However, these materials are often difficult to store in a timely manner after arriving on site, necessitating open or semi-open storage. This storage typically generates a lot of dust, so fixed sprinkler systems or manual watering at regular intervals are usually used for dust suppression. However, the water mist sprayed by fixed sprinkler systems is easily affected by wind. The water mist sprayed from the windward nozzles is easily blown away from the target dust suppression area, resulting in a significant reduction in dust suppression effectiveness. At the same time, the water mist sprayed from the leeward nozzles is overly concentrated due to wind propulsion, leading to excessively high moisture content in some areas of the raw materials, which affects the stability of the subsequent concrete mix design.

[0004] Therefore, in order to solve the above problems, a dust suppression device for the processing of wind power concrete cement poles is proposed. Summary of the Invention

[0005] To address the problems mentioned in the background art, the present invention provides a dust suppression device for processing wind power concrete cement poles, which solves the problem that the spraying device for wind power cement towers is easily affected by wind force during the production process, thus reducing the dust suppression effect on raw materials piled outdoors.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a dust suppression device for processing wind power concrete cement poles, comprising a supporting main pole and a water inlet, wherein a plurality of connecting brackets are arranged in a circular array at the top of the supporting main pole, and a dust suppression component is installed on the connecting brackets; the dust suppression component includes a pipe fitting fixedly installed on the connecting brackets, the pipe fitting having an opening, a valve core rod movably installed inside the pipe fitting, and the valve core rod having a valve core port that can communicate with the opening, wherein in the initial state the communication portion between the opening and the valve core port is half of their respective portions; The top of the main support rod is equipped with a flexible connecting hose that communicates with the port, and the other end of the flexible connecting hose is connected to the top of the main support rod. The top of the main support rod is equipped with an adaptive adjustment component for simultaneously adjusting the movement of several valve core rods. Specifically, for the dust suppression component on the windward side, the adaptive adjustment component can push the valve core rod inward and increase the connection between the valve core orifice and the port. For the dust suppression component on the downwind side, the adaptive adjustment component can pull the valve core rod outward and decrease the connection between the valve core orifice and the port.

[0007] Preferably, a limiting arc block located at one end of the valve core opening is fixedly connected to the valve core rod. The limiting arc block can slide within the opening, and both ends of the limiting arc block can contact the side wall of the opening.

[0008] Preferably, one end of the connecting hose is a connecting part, which is fixedly installed on the outer periphery of the pipe fitting and can communicate with the port.

[0009] Preferably, the adaptive adjustment component includes a support main shaft connected to the top of the support main rod by a ball shaft. The top of the support main shaft is provided with a blade located above the support main rod. A reset spring is fixedly connected to the bottom of the support main shaft below the spherical part. The bottom end of the reset spring is fixedly connected to the support main rod. In the initial state, the bottom end of the support main shaft can maintain a vertical state under the tension of the reset spring. Several double ball-head rods are arranged in a ring around the bottom of the support main shaft and connected to the ball shaft. The other end of the several double ball-head rods is connected to the ball shaft of the valve core rod at the corresponding position. The top cross section of the blade is cross-shaped.

[0010] Preferably, the spherical portion of the supporting spindle is hollow, and the weight on the supporting spindle below the spherical portion is greater than the weight of the blade plus the weight above the spherical portion of the supporting spindle.

[0011] Preferably, the middle part of the pipe fitting is a corrugated connection part, and the part of the pipe fitting away from the adaptive adjustment component can deflect around the corrugated connection part as the axis.

[0012] Preferably, the pipe fitting has a telescopic rod hinged to the top of the inner wall of the corrugated connection portion away from the adaptive adjustment component, and the other end of the telescopic rod is hinged to the bottom of the inner wall of the valve core rod; the telescopic rod is in a retracted state in the initial state, and can be extended when the valve core rod moves away from the corrugated connection portion.

[0013] Preferably, a rubber ring is provided at the top of the main support rod, and the inner wall of the rubber ring can contact the outer wall of the spherical part of the main support shaft.

[0014] Preferably, the top of the support rod is provided with a self-adjusting resistance element for increasing the resistance to the support spindle when it deflects.

[0015] Preferably, the self-adjusting resistance component includes a hollow rubber ring disposed at the top of the support main rod, the hollow rubber ring being able to contact the outer wall of the spherical portion of the support main shaft, a plurality of hollow rods being fixedly connected to the top of the support main rod, the bottom of the hollow rods being able to communicate with the hollow rubber ring, a piston rod being movably connected inside the hollow rods, the top of the piston rods extending above the hollow rods, a circular ring being disposed above the support main rod, the bottom of the circular ring being fixedly connected to a plurality of piston rods, a support spring being sleeved on the outer periphery of the piston rods, and the top and bottom of the support springs being fixedly connected to the circular ring and the hollow rods, respectively; The bottom of the blade is arc-shaped and initially contacts the top of the annular component; several flow guide grilles are provided on the blade.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The above scheme utilizes airflow to deflect the blades, causing the bottom of the supporting shaft to deflect in the opposite direction of the wind. For the dust suppression components on the windward side, the bottom of the supporting shaft pushes the valve core rod via a double ball joint, increasing the overlap area between the inlet and the valve core. This increases the water spray pressure of the dust suppression components to overcome the influence of the airflow. Conversely, for the dust suppression components on the opposite side, the bottom of the supporting shaft pulls the valve core rod in the opposite direction via the double ball joint, reducing the overlap area between the inlet and the valve core. This decreases the water spray pressure of the dust suppression components to prevent excessive concentration of the downstream airflow due to wind propulsion, which could lead to excessively high moisture content in localized raw materials. In the above scheme, when the water spray pressure of the dust suppression component on the windward side increases, the valve core rod will move towards the corrugated connection. At this time, the valve core rod will push the nozzle end of the pipe fitting to deflect upward around the corrugated connection as the axis through the telescopic rod, so that the water sprayed can be sprayed further outward, thereby further reducing the impact of airflow. For the dust suppression component on the windward side, since the valve core rod is in the outward retraction state, the telescopic rod will extend, while the corrugated connection is in the initial state, thus avoiding the nozzle section of the pipe fitting from deflecting downward when the valve core rod retracts. The above-mentioned solution uses a device that, when the blade is driven by wind to deflect the main support shaft in any direction, the bottom of the blade will squeeze the annular component, and the annular component will push the piston rod downward and inject the gas inside the hollow rod into the hollow rubber ring. At this time, the hollow rubber ring will expand and increase the area and pressure with the spherical part of the main support shaft, thereby reducing the friction between the hollow rubber ring and the spherical part of the main support shaft, thus reducing the frequency of the main support shaft during the deflection process and increasing the stability of the main support shaft after deflection.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1 to 8As shown, this invention provides a dust suppression device for processing wind power concrete cement poles, including a supporting main pole 1 and a water inlet 11. A plurality of connecting brackets 12 are arranged in a circular array at the top of the supporting main pole 1, and a dust suppression component 2 is installed on the connecting brackets 12. The dust suppression component 2 includes a pipe fitting 21 fixedly installed on the connecting brackets 12. The pipe fitting 21 has an opening 22, and a valve core rod 23 is movably installed inside the pipe fitting 21. The valve core rod 23 has a valve core port 24 that communicates with the opening 22. In the initial state, the connecting portion between the opening 22 and the valve core port 24 is half of each portion. The top of the supporting main pole 1 is provided with a component that communicates with the opening 22. The connecting hose 3 has one end connected to the top of the supporting main rod 1. One end of the connecting hose 3 is a connecting part 31, which is fixedly installed on the outer periphery of the pipe fitting 21 and can communicate with the port 22. The top of the supporting main rod 1 is provided with an adaptive adjustment component 4 for simultaneously adjusting the movement of several valve core rods 23. For the dust suppression component 2 on the windward side, the adaptive adjustment component 4 can push the valve core rod 23 to move inward and increase the connection between the valve core port 24 and the port 22. For the dust suppression component 2 on the downwind side, the adaptive adjustment component 4 can pull the valve core rod 23 to move outward and decrease the connection between the valve core port 24 and the port 22. The adaptive adjustment component 4 includes a support main shaft 41 connected to the top of the support main rod 1 by a ball shaft. The top of the support main shaft 41 is provided with a blade 42 located above the support main rod 1. The bottom of the support main shaft 41 is fixedly connected to a reset spring 44 located below the spherical part. The bottom end of the reset spring 44 is fixedly connected to the support main rod 1. In the initial state, the bottom end of the support main shaft 41 can maintain a vertical state under the tension of the reset spring 44. Several double ball-head rods 43 are arranged in a ring around the bottom of the support main shaft 41 and connected to the ball shaft. The other end of the several double ball-head rods 43 is connected to the ball shaft of the valve core rod 23 at the corresponding position. The top cross section of the blade 42 is cross-shaped. Using the above scheme, the airflow will blow the blades 42 to deflect them, and the bottom of the supporting main shaft 41 will deflect in the opposite direction of the wind. At this time, for the dust suppression component 2 on the windward side, the bottom of the supporting main shaft 41 will push the valve core rod 23 to move through the double ball head rod 43, thereby increasing the overlapping area of ​​the through-hole 22 and the valve core port 24, thus increasing the water spray pressure of the dust suppression component 2 to overcome the influence of the airflow. For the dust suppression component 2 on the opposite side of the wind, the bottom of the supporting main shaft 41 will pull the valve core rod 23 to move in the opposite direction through the double ball head rod 43, and reduce the overlapping area of ​​the through-hole 22 and the valve core port 24, thereby reducing the water spray pressure of the dust suppression component 2 to avoid the problem of excessive concentration of the downwind airflow due to wind boost, which would lead to excessively high local raw material moisture content. It should be noted that in the absence of wind, the supporting spindle 41 will be held vertical by the tension of the reset spring 44.

[0021] like Figure 4As shown, a limiting arc block 231 located at one end of the valve core port 24 is fixedly connected to the valve core rod 23. The limiting arc block 231 can slide within the through port 22, and both ends of the limiting arc block 231 can contact the side wall of the through port 22. By adopting the above solution, the limiting arc block 231 is set on the outer periphery of the valve core rod 23, so that the limiting arc block 231 slides in the port 22, thereby driving the limiting effect on the valve core rod 23 when it moves, thus avoiding the misalignment of the port 22 and the valve core port 24 in the circumferential direction.

[0022] like Figure 5 and Figure 7 As shown, the spherical part of the supporting main shaft 41 is hollow, and the weight of the supporting main shaft 41 below the spherical part is greater than the weight of the blade 42 plus the weight of the supporting main shaft 41 above the spherical part. By adopting the above scheme, the weight of the supporting spindle 41 is specially set so that the supporting spindle 41 can be in a vertical state in the initial state, and the pressure on the reset spring 44 can be reduced when the supporting spindle 41 is reset.

[0023] like Figure 4 and Figure 5 As shown, the middle part of the pipe component 21 is a corrugated connection part 211, and the part of the pipe component 21 away from the adaptive adjustment component 4 can deflect around the corrugated connection part 211 as the axis. The top of the inner wall of the corrugated connection 211 away from the adaptive adjustment component 4 is hinged with a telescopic rod 6, and the other end of the telescopic rod 6 is hinged to the bottom of the inner wall of the valve core rod 23. In the initial state, the telescopic rod 6 is in a retracted state, and when the valve core rod 23 moves away from the corrugated connection 211, the telescopic rod 6 can be extended. Using the above scheme, when the water spray pressure of the dust suppression component 2 on the windward side increases, the valve core rod 23 will move towards the corrugated connection 211. At this time, the valve core rod 23 will push the nozzle end of the pipe component 21 to deflect upward around the corrugated connection 211 through the telescopic rod 6, so that the water sprayed can be sprayed further outward, thereby further reducing the influence of airflow. For the dust suppression component 2 on the windward side, since the valve core rod 23 is in the outward retraction state, the telescopic rod 6 will extend, while the corrugated connection 211 is in the initial state, thus avoiding the nozzle section of the pipe component 21 from deflecting downward when the valve core rod 23 retracts.

[0024] like Figure 1 , Figure 2 , Figure 5 , Figure 7 and Figure 8As shown, a rubber ring 13 is provided at the top of the main support rod 1, and the inner wall of the rubber ring 13 can contact the outer wall of the spherical part of the main support shaft 41; a self-adjusting resistance member 5 is provided at the top of the main support rod 1 to increase the resistance to the main support shaft 41 when it deflects. The self-adjusting resistance component 5 includes a hollow rubber ring 51 disposed at the top of the support main rod 1. The hollow rubber ring 51 can contact the outer wall of the spherical part of the support main shaft 41. Several hollow rods 52 are fixedly connected to the top of the support main rod 1. The bottom of the hollow rods 52 can communicate with the hollow rubber ring 51. A piston rod 53 is movably connected inside the hollow rod 52. The top of the piston rod 53 extends above the hollow rod 52. A ring 54 is disposed above the support main rod 1. The bottom of the ring 54 is fixedly connected to several piston rods 53. A support spring 521 is sleeved on the outer periphery of the piston rod 53. The top and bottom of the support spring 521 are fixedly connected to the ring 54 and the hollow rod 52, respectively. The bottom of the blade 42 is arc-shaped and initially contacts the top of the annular component 54; several guide grilles 421 are provided on the blade 42. By adopting the above scheme, when the blade 42 is driven by the wind to deflect the main shaft 41 in any direction, the bottom of the blade 42 will squeeze the ring 54, and the ring 54 will push the piston rod 53 downward and inject the gas in the hollow rod 52 into the hollow rubber ring 51. At this time, the hollow rubber ring 51 will expand and increase the area and pressure with the spherical part of the main shaft 41, thereby reducing the friction between the hollow rubber ring 51 and the spherical part of the main shaft 41, so as to reduce the frequency of the main shaft 41 during the deflection process and increase the stability of the main shaft 41 after deflection.

[0025] Working principle and usage process of this invention: When encountering airflow during dust suppression operation, the airflow will blow the blades 42, causing them to deflect. The bottom of the supporting main shaft 41 will deflect in the opposite direction of the wind. At this time, for the dust suppression component 2 on the windward side, the bottom of the supporting main shaft 41 will push the valve core rod 23 to move through the double ball joint rod 43, thereby increasing the overlapping area of ​​the orifice 22 and the valve core orifice 24. This will increase the water spray pressure of the dust suppression component 2 to overcome the influence of the airflow. For the dust suppression component 2 on the opposite side of the wind, the bottom of the supporting main shaft 41 will pull the valve core rod 23 to move in the opposite direction through the double ball joint rod 43, and reduce the overlapping area of ​​the orifice 22 and the valve core orifice 24. This will reduce the water spray pressure of the dust suppression component 2 to avoid the problem of excessive concentration of the downstream airflow due to wind boost, which could lead to excessively high local raw material moisture content. When the water spray pressure of the dust suppression component 2 on the windward side increases, the valve core rod 23 will move towards the corrugated connection 211. At this time, the valve core rod 23 will push the nozzle end of the pipe component 21 to deflect upward around the corrugated connection 211 through the telescopic rod 6, so that the water sprayed can be sprayed further outward, thereby further reducing the influence of airflow. On the other hand, for the dust suppression component 2 on the windward side, since the valve core rod 23 is in the outward retraction state, the telescopic rod 6 will extend, while the corrugated connection 211 is in the initial state, thus preventing the nozzle section of the pipe component 21 from deflecting downward when the valve core rod 23 retracts. When the blade 42 is driven by the wind to deflect the main shaft 41 in any direction, the bottom of the blade 42 will squeeze the ring 54, and the ring 54 will push the piston rod 53 downward and inject the gas in the hollow rod 52 into the hollow rubber ring 51. At this time, the hollow rubber ring 51 will expand and increase the area and pressure with the spherical part of the main shaft 41, thereby reducing the friction between the hollow rubber ring 51 and the spherical part of the main shaft 41, reducing the frequency of the main shaft 41 during the deflection process and increasing the stability of the main shaft 41 after deflection.
