Description

Technical Field

[0001] The present invention relates to the technical field of construction site dust reduction, and more specifically, to an Internet of Things dust reduction device for construction site. Background Art

[0002] In the construction industry, traditional construction methods have always faced many challenges, such as low efficiency, safety hazards, waste of resources, etc. However, with the continuous development of science and technology, the emergence of smart construction site IoT applications is gradually changing this situation. By applying IoT technology to construction site management, real-time monitoring, information sharing, intelligent analysis and other functions of the construction site can be realized, thereby improving construction efficiency, reducing costs and ensuring project quality.

[0003] Through the application of the Internet of Things in smart construction sites, real-time monitoring of the construction site can be achieved, and potential safety hazards can be discovered and dealt with in a timely manner. For example, through sensors installed on the construction site, environmental parameters such as temperature, humidity, and wind speed can be monitored in real time to ensure the safety of the construction environment. In addition, through the application of the Internet of Things in smart construction sites, real-time information sharing can be achieved to improve construction efficiency.

[0004] Among them, during the construction process at the construction site, a large amount of general dust such as suspended particles and inhalable particles that are harmful to the atmosphere will be generated. These particles floating in the air will cause great harm to the health of construction workers. At the same time, they will also pollute the surrounding environment and have a huge impact on the surrounding residents. Therefore, good dust reduction treatment is required during the construction process.

[0005] The existing spray dust suppression devices used in construction sites are mostly mist spray dust suppression devices, which mainly fix the spray head and the spray pipe on the upper end of the fence of the construction site to form a fence spray system. During the construction process, the outward diffusion of dust in the construction site is reduced. However, in the actual construction process, a large amount of dust may be temporarily generated at the actual construction location. For example, during the construction process such as earth excavation, concrete mixing, and material loading and unloading, a large amount of dust will be generated in the corresponding area of ​​the construction site. At this time, the fence spray system on the fence cannot accurately carry out dust reduction treatment in a certain area. At this time, it is necessary to use a specific independent spray dust suppressor (such as a fog cannon) to aim at the The construction area is treated with separate dust reduction, and based on the construction site Internet of Things control system, corresponding fog cannon dust reduction equipment is set in some areas of the construction site. Combined with the construction conditions (construction process that generates dust, construction location and construction time, etc.) and construction environment parameters (temperature, humidity, wind direction and wind speed, etc.), the corresponding independent spray dust suppressor is turned on, and the corresponding spray angle and spray direction and other parameters are given to carry out separate dust reduction treatment for specific areas. In particular, according to the wind direction parameters of the construction environment, the independent spray dust suppressor is preferentially placed downwind so that the water mist sprayed by the independent spray dust suppressor can combine sharply and more effectively with the dust to carry out dust reduction.

[0006] However, due to the complex location of some construction sites and the restrictions of the environment outside the construction sites, some construction sites are close to the site fence, that is, a large amount of dust is generated closer to the site boundary. If the dust height is high, if the wind direction is towards the site boundary and the dust generation and diffusion height is high, if only one independent spray dust suppressor is set at the upwind position of the dust generation point, then after the water mist combines with the dust, it is affected by the power of the independent spray dust suppressor itself in the direction of the water mist sprayed and the wind force of the on-site environment, and the water mist combined with the dust is easily blown out of the site fence, causing a great impact on the environment outside the site.

[0007] In order to reduce the occurrence of the above-mentioned phenomenon, after processing and analysis by the construction site Internet of Things control system, a group of independent spray dust suppressors can be set at the corresponding position downwind of the dust generation point, that is, the area between the dust generation point and the construction site fence. They can spray water mist in the opposite direction of the on-site ambient wind, giving the dust and the previous group of water mist a wind force away from the construction site fence, thereby reducing the outward expansion of dust and protecting the environmental safety of the area near the construction site.

[0008] However, since this group of independent spray dust suppressors is set up against the wind, in actual use, some of the water mist carrying dust will move toward the independent spray dust suppressor itself, especially when the water mist carrying dust moves in this direction after shutdown, it is easy to carry the fusion of dust and water to the vicinity of the nozzle of the independent spray dust suppressor. Along with the air flow on the surface of the nozzle and the irregular movement of dust in the aqueous solution, the dust enters the nozzle nozzle hole. After the water evaporates, the dust is easy to block the nozzle hole, affecting the subsequent dust reduction effect, especially affecting the actual operating parameters of the independent spray dust suppressor, affecting the precise control of the construction site Internet of Things control system, and if the blockage is serious, it will also cause certain damage to the equipment and cause losses. Summary of the invention

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Refer to the instruction manual Figures 1 to 11The present invention provides an Internet of Things dust suppression device for construction sites, including an independent spray dust suppressor 1 and an enclosure spray system 2, wherein the enclosure spray system 2 is arranged on the construction site enclosure b of the construction site a, and is mainly composed of a spray pipe and a spray head to form a spray boundary to prevent dust from overflowing. Since the implementation scheme of the enclosure spray system 2 is a basic scheme commonly used in existing construction sites, this embodiment will not be explained in detail. The independent spray dust suppressor 1 includes a mobile base 11 and a wind tube 13, and the wind tube 13 is connected to the mobile base 11 through an adjustment seat assembly 12. An exhaust assembly 4 is arranged inside the wind tube 13, and a spray assembly 5 is arranged at one end of the wind tube 13, and the end is an air outlet end. Specifically, the spray assembly 5 Spraying is performed at the port of the wind tube 13, and the exhaust component 4 forms a directional airflow in the wind tube 13, blowing the water mist toward the dust, so that the water mist combines with the dust and separates and settles with the air to achieve dust reduction operation. The exhaust component 4 is composed of a fan blade component 41 and an exhaust motor 42. The fan blade component 41 is rotatably installed in the interior of the wind tube 13, and the exhaust motor 42 is fixedly installed in the interior of the wind tube 13. The fan blade component 41 is installed on the output shaft of the exhaust motor 42. A bracket structure for supporting the fan blade component 41 and the exhaust motor 42 is provided in the wind tube 13. Then, by driving the fan blade component 41 to rotate at a high speed, a high-speed airflow can be formed in the wind tube 13, and the airflow generated by the spray component 5 at the end of the wind tube 13 can be blown out.

[0041] The spray assembly 5 includes a water supply ring frame 51, on which a plurality of atomizing nozzles 52 are arranged. The water supply ring frame 51 is connected to a water injection pipe 54, and the water injection pipe 54 is connected to a water pump through a pipeline. The water pump is a high-pressure pump, and the water injection pipe 54 is a high-pressure water injection pipe. The water pump can be fixedly installed in the mobile base 11, and the water pump is connected to the construction site water tank, and then high-pressure water is input into the water supply ring frame 51 through the water pump through the water injection pipe 54, so that the atomizing nozzle 52 can spray uniform water mist at the port of the wind tube 13. The water supply ring frame 51 is rotatably arranged at the end of the wind tube 13, and a ring frame driving assembly 6 is installed on the wind tube 13. The ring frame driving assembly 6 is used to drive the water supply ring frame 51 to rotate.

[0042] In actual use, refer to the instructions attached. Figure 2When the dust generating point c is too close to the construction site fence b, and the dust generation intensity is large, and the fence spray system 2 cannot complete the dust reduction operation alone, it is necessary to cooperate with the independent spray dust suppressor 1 near the dust generating point c for combined dust reduction, especially when the ambient wind d in the on-site environment is blowing from the dust generating point c to the construction site fence b, at this time, in addition to opening the independent spray dust suppressor 1 at the upwind port of the dust generating point c, it is also necessary to open a group of independent spray dust suppressors 1 at the downwind port of the dust generating point c. The airflow intensity of this group of independent spray dust suppressors 1 is higher, and the water mist spray range is wider, thereby reducing water mist and dust. In combination with the dispersion of liquid to the outside of the construction site fence b, for the independent spray dust suppressor 1, the water pump supplies water to the water supply ring frame 51, and the atomizing nozzle 52 sprays water mist, and is sprayed to the position where dust reduction is required through the air flow blown out by the exhaust component 4. During the use of the independent spray dust suppressor 1, by driving the water supply ring frame 51 to rotate, centrifugal force can be generated to throw the water attached to the surface of the atomizing nozzle 52 and the dust in the water outward, avoiding the formation of mud on the surface of the atomizing nozzle 52, thereby greatly reducing the phenomenon of dust clogging the spray hole of the atomizing nozzle 52, thereby improving the use effect and service life of the equipment.

[0043] It should be noted that by controlling the rotation of the water supply ring frame 51, while increasing the rotation speed of the water supply ring frame 51, a certain centrifugal force can be generated on the water mist sprayed from the atomizing nozzle 52, thereby causing the water mist to diffuse outward, and the greater the rotation speed of the water supply ring frame 51, the greater the diffusion range of the water mist, thereby changing the overall diffusion effect of the water mist blown out by the independent spray dust suppressor 1 (for example, when the rotation speed of the water supply ring frame 51 is low, the water mist is overall in a clustered shape, and when the rotation speed of the water supply ring frame 51 is high, the water mist is overall in a diffuse shape), thereby being able to better adapt to actual dust reduction conditions.

[0044] For further information, please refer to the attached manual. Figure 1 A control host 3 (such as a computer or other smart mobile terminal) is also provided on the mobile base 11. The control host 3 establishes a connection with the Internet of Things control system of the construction site through the Internet, and obtains various detection parameters of the Internet of Things control system of the construction site, such as the location of the construction site a, the wind direction of the ambient wind d, etc., and then according to actual needs, the independent spray dust collector 1 at the corresponding position is turned on and the actual dust reduction parameters of the independent spray dust collector 1 are adjusted, so as to achieve better dust reduction control. Figure 3The adjusting seat assembly 12 includes a fixed seat 121, a rotating seat 122 and a swinging seat 123. The fixed seat 121 is fixedly mounted on the movable base 11, the rotating seat 122 is rotatably mounted on the fixed seat 121 with a vertical axis as a rotating axis, and the swinging seat 123 is rotatably mounted on the rotating seat 122 with a horizontal axis as a rotating axis. The wind tube 13 is fixedly mounted on the swinging seat 123, and a rotating driver for driving the rotating seat 122 to rotate is arranged between the fixed seat 121 and the rotating seat 122, and a swinging driver for driving the swinging seat 123 to flip and swing is arranged between the rotating seat 122 and the swinging seat 123. The above-mentioned rotating driver and swinging driver can be freely selected according to actual needs, for example, a rotating driving motor, a flip driving hydraulic cylinder, etc. can be selected, and the corresponding driving equipment can also be freely designed in actual use to realize the left and right angle adjustment and the up and down pitch angle adjustment of the wind tube 13, so that it can be controlled in real time through the Internet of Things control system to achieve the best dust reduction effect.

[0045] In the above-mentioned embodiments, refer to the attached specification. Figure 4 A ring frame support seat 53 is fixedly installed in the end of the wind cylinder 13, and the water supply ring frame 51 is rotatably installed on the ring frame support seat 53. The outside of the water supply ring frame 51 is fixedly connected with a first gear ring 511. The ring frame drive assembly 6 includes a motor structure 61, and the motor structure 61 is fixedly installed on the wind cylinder 13. A gear is fixedly installed on the output shaft of the motor structure 61, and the gear is meshed with the first gear ring 511 to achieve transmission cooperation between the motor structure 61 and the water supply ring frame 51, thereby realizing the rotation drive of the water supply ring frame 51, wherein the water supply ring frame 51 can rotate continuously or reciprocate rapidly.

[0046] It should be noted that, in order to ensure the centrifugal effect, the water supply ring frame 51 preferably rotates continuously. At this time, if the water injection pipe 54 is directly fixedly connected to the water supply ring frame 51, the corresponding connected pipe will form an obstacle. Therefore, this embodiment provides an effective rotation scheme for the water supply ring frame 51. For details, refer to the attached manual. Figure 7The ring frame support seat 53 includes a support ring plate 531 and a limiting pressure sleeve 532. The support ring plate 531 is fixedly installed in the wind tube 13. The limiting pressure sleeve 532 is sleeved on the outside of the water supply ring frame 51, and the limiting pressure sleeve 532 is fixedly connected to the support ring plate 531. A mutually limiting protrusion structure 514 is provided between the limiting pressure sleeve 532 and the water supply ring frame 51, and a sealing structure is provided between the water supply ring frame 51 and the support ring plate 531 and the limiting pressure sleeve 532. Then, by assembling the limiting pressure sleeve 53 2 and the support ring plate 531, the water supply ring frame 51 can be installed in the wind tube 13, and the rotation of the water supply ring frame 51 is jointly supported by the support ring plate 531 and the limiting pressure sleeve 532. At the same time, the water supply ring frame 51 is a hollow structure, and the side of the water supply ring frame 51 corresponding to the support ring plate 531 is set as an open end, the water injection pipe 54 is fixedly connected to the support ring plate 531, and the water injection pipe 54 is set corresponding to the inner cavity 513 of the water supply ring frame 51, and the atomizing nozzle 52 is connected to the inner cavity 513 of the water supply ring frame 51.

[0047] Furthermore, in the above-mentioned embodiment, water at the part of the atomizing nozzle 52 close to the outside of the wind tube 13 is more easily thrown out, but water at the side of the atomizing nozzle 52 away from the outside of the wind tube 13 is not easy to be thrown out due to the obstruction of the atomizing nozzle 52 itself. To solve this problem, the present embodiment also provides the following technical solutions. Specifically, a rotating sleeve 512 is provided on the water supply ring frame 51, and the atomizing nozzle 52 is rotatably inserted in the rotating sleeve 512, and a sealing structure is provided between the atomizing nozzle 52 and the side wall of the rotating sleeve 512.

[0048] For further information, please refer to the attached manual. Figure 7 A reaming section is provided inside one end of the atomizing nozzle 52 located in the inner cavity 513 of the water supply ring frame 51. The reaming section is located in the channel of the atomizing nozzle 52, and a self-rotating blade 521 is fixedly installed in the reaming section. Therefore, in actual use, the high-pressure water input by the water injection pipe 54 will flow out through the channel of the atomizing nozzle 52 and form a water flow in the channel of the atomizing nozzle 52. When the water flow flows through the self-rotating blade 521, it will form a reaction force on the self-rotating blade 521, prompting the atomizing nozzle 52 to rotate, thereby driving the atomizing nozzle 52 to rotate, thereby improving the effect of throwing water off the surface of the atomizing nozzle 52.

[0049] Refer to the instruction manual Figure 8 and Fig. 9The present embodiment also provides another self-rotation driving scheme of the atomizing nozzle 52. Specifically, a second gear ring 522 is fixedly installed on the outside of the atomizing nozzle 52, and an arc-shaped bracket 55 is provided in the inner wall of the wind tube 13. An arc-shaped rack 551 is installed on the arc-shaped bracket 55. When the atomizing nozzle 52 moves to the arc-shaped bracket 55, the second gear ring 522 and the arc-shaped rack 551 are meshed with each other, thereby realizing the self-rotation driving of the atomizing nozzle 52. In addition, the atomizing nozzle 52 is driven in this way. The self-rotation speed of the atomizing nozzle 52 is fast. In addition to being able to adjust the change of the atomizing nozzle 52, the centrifugal force generated by its own rotation also helps to throw out the water on the surface of the atomizing nozzle 52, further improving the protection effect.

[0050] In the above embodiment, facing the cold weather in winter, water is easy to freeze. Since the water flow sprayed by the atomizing nozzle 52 is in a continuous flow state and is not easy to freeze, the spray hole of the atomizing nozzle 52 is not easy to be blocked during continuous use. However, the water layer attached to the surface of the atomizing nozzle 52 is easily affected by the low temperature and freezes, thereby affecting the throwing effect, and easily causing the mud on the surface of the atomizing nozzle 52 to freeze and not be easily thrown out. In addition, due to the continuous coverage of water, the thickness of the ice layer will be thickened, thereby affecting the spray effect of the atomizing nozzle 52. For this reason, refer to the attached manual. Fig. 9 , this embodiment also provides the following technical solutions. Specifically, a locking groove is provided in the arc bracket 55, and the arc rack 551 is movably mounted in the locking groove in the arc bracket 55, and a guide structure (such as a guide groove) is provided between the arc rack 551 and the arc bracket 55. The guide structure is used to limit the sliding of the arc rack 551 in the arc bracket 55 along the radial direction of the water supply ring frame 51, and an elastic connecting member 552 (such as a spring) is connected between the arc rack 551 and the arc bracket 55. When the second gear ring 522 contacts the arc rack 551, in addition to enabling the atomizing nozzle 52 to rotate, a certain vibration impact will be generated, thereby breaking the ice layer already formed on the surface of the atomizing nozzle 52 and throwing it out, thereby improving the use effect and reducing the influence of temperature on the spray condition of the atomizing nozzle 52.

[0051] Based on the above implementation, in order to further avoid the impact of low winter temperatures on the equipment, this embodiment also provides the following technical solutions. Fig.10 A plurality of electric heating components 7 are fixedly installed inside the air duct 13, and the air inside the air duct 13 can be heated by means of the electric heating components 7. When used in winter, a heating effect can be formed on the atomizing nozzle 52 to prevent the atomizing nozzle 52 from being frozen.

[0052] In addition, even if the ambient temperature is normal and no icing occurs, during actual use of the device, due to the spread and uncontrollability of dust, some dust will drift to the rear of the wind tube 13 and be sucked into the wind tube 13, accompanied by water mist in the air, and adhere to the inner wall of the wind tube 13 and the inner surface of the atomizing nozzle 52. At this time, in order to avoid dust adhesion, the electric heating component 7 can also be turned on to increase the air temperature in the wind tube 13, evaporate the water, and reduce the adhesion effect. At the same time, in order to prevent the dust that enters the wind tube 13 in the reverse direction from flowing to the inner surface of the atomizing nozzle 52, refer to the attached manual. Fig.11 , this embodiment also provides the following technical solutions, specifically, an air guide assembly 8 is provided at a position near the spray assembly 5 in the inner wall of the air duct 13, the air guide assembly 8 includes a fixed sleeve 81 and a drainage sleeve 82, the drainage sleeve 82 is fixedly connected to the fixed sleeve 81, the fixed sleeve 81 is fixedly installed in the air duct 13, a parallel guide space is formed between the drainage sleeve 82 and the fixed sleeve 81, a filter structure 83 is fixedly installed in the parallel guide space, and one end of the atomizing nozzle 52 close to the water supply ring frame 51 is bent toward the water supply ring frame 51, In actual use, the fan blade assembly 41 can cause the dust to gather on the inner wall of the wind tube 13 and be carried by the air flow to move to the water supply ring frame 51, where the dust is filtered by the filtering structure 83 to reduce the contact between the dust and the atomizing nozzle 52 and the combination with the water on its surface, thereby reducing the occurrence of mud.
