Description

Technical Field

[0001] This invention relates to the field of atomized dust suppression technology, specifically a dust suppression device for building construction. Background Technology

[0002] In actual construction sites, fog cannons are widely used. Long-term exposure to dusty environments can easily cause respiratory diseases. Fog cannons can control the dust concentration in the work area within a safe range. Fog cannons adsorb dust by atomizing water particles under high pressure, which can reduce the concentration of inhalable particulate matter in the air. Current dust suppression devices can usually adjust the spray angle by pitch and the fan speed is constant. The atomization effect is excellent when spraying at an upward angle. However, when spraying at a low angle, the spray distance is reduced due to ground obstruction. The high-pressure water mist from the nozzle will contact the ground prematurely, resulting in an overly concentrated spray position and poor water mist diffusion. Moreover, maintaining high wind pressure at this time can further increase dust. It is not convenient to automatically control and adjust the spray wind pressure and assist diffusion. At the same time, when traditional fog cannons swing to spray dust suppression, the water mist they spray is fan-shaped, which is not flexible in use and is not convenient for automatic control to compensate for the spray distance. It also requires multiple adjustments to the position.

[0003] Therefore, we propose a dust suppression device for building construction. Summary of the Invention

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.

[0031] Example 1: Please refer to Figures 1 to 11 As shown:

[0032] This invention provides a technical solution: a dust suppression device for construction, comprising a dust suppression mounting component 1, a mist cannon dust suppression component 2 mounted on the dust suppression mounting component 1, the mist cannon dust suppression component 2 being used for dust suppression; a diffusion control component 3 mounted on the mist cannon dust suppression component 2; the diffusion control component 3 being used to adjust the spray force according to the spray distance of the mist cannon dust suppression component 2; a diffusion auxiliary component 4 mounted on the mist cannon dust suppression component 2; an atomizing spray section 5 mounted on the mist cannon dust suppression component 2; the diffusion auxiliary component 4 being used to increase the atomization area of ​​the atomizing spray section 5; a swing compensation component 6 mounted on the dust suppression mounting component 1; the swing compensation component 6 being used to improve the straightness of the spray area when swinging for dust suppression; the dust suppression mounting component 1 includes: a water tank 101 and a water pump 102, the water pump 102 being fixedly installed inside the water tank 101; a water inlet being provided at the top of the water tank 101; and four support pads being provided at the bottom of the water tank 101.

[0033] The dust suppression mounting component 1 includes: a drive motor 103, which is fixedly mounted on the top side inside the water tank 101, and the drive motor 103 is provided with a waterproof shell on its outside; the output shaft of the drive motor 103 passes through the water tank 101; the fog cannon dust suppression component 2 includes: a rotating frame 201, a fog cannon 202, an extrusion block 203, a main fan 204, and a compensating fan 205, the rotating frame 201 is fixedly mounted on the output shaft of the drive motor 103; the rotating frame 201 is located above the water tank 101; the fog cannon 202 is rotatably mounted on the rotating frame 201; the tail of the fog cannon 202 is provided with a dustproof net; the extrusion block 203 is fixedly mounted on the bottom of the rotating frame 201; the extrusion block 203 has a sloping structure on both sides; the main fan 204 is fixedly mounted inside the fog cannon 202 through a bracket; the fog cannon 202 is connected to the main fan 204 through a bracket. A compensating fan 205 is fixedly installed on the bracket; the compensating fan 205 and the main fan 204 are respectively composed of a motor and an impeller; the front side of the fog cannon 202 has a sloping constriction structure; the diffusion control component 3 includes: a swing adapter arm 301, an electric push rod 302, a propulsion block 303, a main sliding rheostat 304, and a connecting rod 305. The swing adapter arm 301 is rotatably installed on the rotating frame 201; the electric push rod 302 is fixedly sleeved on the swing adapter arm 301, and the propulsion block 303 is fixedly installed on the output shaft of the electric push rod 302; the propulsion block 303 is rotatably installed at the bottom of the fog cannon 202; the electric push rod 302 is used to push the fog cannon 202 to adjust the pitch angle; the two sides of the swing adapter arm 301 are respectively fixedly installed with main sliding rheostats 304, and the two main sliding rheostats 304 have different rheostat specifications;Connecting rods 305 are fixedly installed on both sides of the propulsion block 303, and the ends of the two connecting rods 305 are respectively connected to the rheostat rings of the two main sliding rheostats 304. Using the dust suppression mounting component 1, in conjunction with the fog cannon dust suppression component 2, the pitch angle can be flexibly adjusted and the atomization dust suppression area can be expanded by swinging back and forth. Using the diffusion control component 3, in conjunction with the fog cannon dust suppression component 2, allows for automatic control of wind force adjustment when adjusting the pitch atomization spray angle, improving the atomization dust suppression effect in practical applications. This avoids the problem of the ground being too concentrated and the water mist pressure being too high and concentrated when spraying at low angles, causing the water mist to not diffuse properly, resulting in muddy ground at the center of the spray and poor dust suppression effect around it. Furthermore, when spraying at low angles, maintaining... High-pressure spraying can easily increase dust and reduce the dust suppression effect. This structure can achieve automatic control without manual adjustment. During actual atomization dust suppression, the electric push rod 302 can advance the fog cannon 202 to adjust its pitch. During the process, when the electric push rod 302 extends or retracts, it can drive the two connecting rods 305 on the push block 303 to respectively move the positions of the variable resistance rings on the two main sliding rheostats 304. When the variable resistance ring on the main sliding rheostat 304, which is electrically connected to the main fan 204, moves downward, that is, when the fog cannon 202 rotates downward, if the rotation angle is too low, the resistance value of the corresponding main sliding rheostat 304 gradually increases. At this time, the wind speed of the main fan 204 decreases, which can reduce the problem of concentrated spray when spraying at low angles, reduce the spray speed, and reduce the problem of excessive local humidity. There is no need for cumbersome relocation of this structure.

[0034] The diffusion auxiliary component 4 includes: an outward-expanding jet ring 401 and a diffusion connecting pipe 402. The outward-expanding jet ring 401 is fixedly installed on the inner side of the front end of the fog cannon 202 by a bracket; the outward-expanding jet ring 401 is provided with an outwardly angled jet groove; the diffusion connecting pipe 402 is fixedly connected to the outward-expanding jet ring 401; the diffusion connecting pipe 402 communicates with the outward-expanding jet ring 401; the diffusion connecting pipe 402 passes through the fog cannon 202; the diffusion auxiliary component 4 also includes: an electric fan 403, which is fixedly installed on the water tank 101, and the electric fan... A diffuser connecting pipe 402 is fixedly installed on 403, and the diffuser connecting pipe 402 is connected to the electric fan 403; two main sliding rheostats 304 are electrically connected to the electric fan 403 and the main fan 204 respectively; the two main sliding rheostats 304 are used to control the speed of the main fan 204 to decrease and the speed of the electric fan 403 to increase when the electric push rod 302 retracts; the electric fan 403, the main fan 204, the compensating fan 205 and the water pump 102 are each externally connected to a speed controller; the atomizing spray section 5 includes: an atomizing pipe 501 and a water supply pipe 502. Two atomizing tubes 501 are provided, each with a ring of atomizing nozzles. The two atomizing tubes 501 are fixedly mounted on the fog cannon tube 202. The two atomizing tubes 501 are located on both sides of the outer diffuser ring 401. A water supply pipe 502 is fixedly installed on each atomizing tube 501. The water supply pipe 502 is connected to the outlet of the water pump 102. The atomizing spray section 5, in conjunction with the diffusion auxiliary component 4, further enhances the actual dust suppression effect of this structure. For low-angle spraying, the outer diffuser ring 401 can be used to further improve the effect. To ensure that the water mist can diffuse outward and prevent excessive concentration, thus improving the dust suppression quality of this structure, when the electric push rod 302 extends or retracts, the variable resistance ring on the main sliding rheostat 304, which is electrically connected to the electric fan 403, moves downward. If the travel distance is too large, that is, when the angle of the mist cannon 202 is too low, the resistance value of the main sliding rheostat 304 corresponding to the electric fan 403 gradually decreases. The electric fan 403 can then be gradually controlled to start and increase the wind force, spreading some of the water mist sprayed from the atomizing tube 501 outward, and assisting the low-speed main fan 204 in spreading the water mist.

[0035] In Example 2, based on Example 1, the swing compensation component 6 includes: a swing detection block 601 and a sliding limit block 602. The swing detection block 601 has a V-shaped groove on its side. The side of the swing detection block 601 is attached to the compression block 203. The sliding limit block 602 is fixedly installed on the water tank 101 by two bolts. The swing detection block 601 is slidably installed on the inner side of the sliding limit block 602, and the swing detection block 601 is located above the water tank 101. The edge of the swing detection block 601 is chamfered. The swing compensation component 6 also includes: a tension spring pawl 603 and a compensation sliding rheostat 604. The tension spring pawl 603 is fixedly installed on the sliding limit block 602. A tension spring is connected to the tension spring lever 603, and the end of the tension spring on the tension spring lever 603 is connected to the sliding limit block 602; a compensating sliding rheostat 604 is fixedly installed on the sliding limit block 602; the tension spring on the tension spring lever 603 is used to pull the swing detection block 601 to elastically fit against the compression block 203; the swing compensation component 6 also includes: a rheostat connecting piece 605, which is fixedly installed on the rheostat ring of the compensating sliding rheostat 604; the rheostat connecting piece 605 is fixedly installed on the tension spring lever 603. The use of the swing compensation component 6 can improve the structure and optimize the spray trajectory when swinging to increase the dust atomization area. The original fan-shaped spray trajectory can be optimized to a triangular shape, adjusting the arc-shaped trajectory at the spray tip to increase its straightness. This improves the flexibility of the structure in practical applications and makes it better suited for straight construction boundaries, such as foundation pit excavation. It avoids excessive concentration of water mist in the area directly facing the spray, which could lead to excessive humidity on the pit walls. Furthermore, the oscillating spray pattern prevents the spray area from completely covering the edge of the excavation pit. Additionally, when using ground spray for dust suppression, the fan-shaped spray trajectory makes it easier for the mist to disperse beyond the outer perimeter of the construction site. Workers can control whether to use the compensating fan 205, which is located on the rotating frame 201. When the moving fog cannon 202 swings back and forth, it can drive the squeezing block 203 to squeeze the swing detection block 601 with the inclined plane, which stretches the spring on the tension spring 603. When the tension spring 603 moves, it will drive the rheostat connecting piece 605 to move the rheostat ring on the compensating sliding rheostat 604. At this time, as the squeezing block 203 swings, regardless of the direction, as long as the tip of the squeezing block 203 does not pass the swing detection block 601, the resistance of the compensating sliding rheostat 604 will gradually decrease. At this time, as the swing angle gradually increases, the speed of the compensating fan 205 also gradually increases, increasing the spray distance, thereby compensating for the offset of the spray end as the spray swings.

[0036] The working principle of this embodiment is as follows: The water tank 101 is placed on the ground, or a cement platform can be built on the ground and the water tank 101 is placed on the cement platform. Water is added through the water inlet at the top of the water tank 101. The main fan 204 can be started. The base speed of the main fan 204 is adjusted in advance to generate wind power. The water pump 102 is started to guide the water in the water tank 101 into the atomizing pipe 501, and sprayed out through the atomizing nozzle on the atomizing pipe 501. With the wind power generated by the main fan 204, the water is sprayed out with force. The drive motor 103 can drive the rotating frame 201 to drive the mist cannon 202 to swing back and forth to adjust the spray direction. The electric push rod 302 can be used to push the mist cannon 202 to adjust the pitch. During the process, when the electric push rod 302 extends or retracts, it can drive the push rod to adjust the pitch. The two connecting rods 305 on the input block 303 respectively move the positions of the variable resistance rings on the two main sliding rheostats 304. When the variable resistance ring on the main sliding rheostat 304, which is electrically connected to the main fan 204, moves downward, that is, when the mist cannon 202 rotates downward, if the rotation angle is too low, the resistance of the corresponding main sliding rheostat 304 gradually increases. At this time, the wind speed of the main fan 204 decreases, which can reduce the problem of concentrated spray when spraying at low angles and reduce the spray speed, thus reducing the problem of excessive local humidity. Conversely, when the mist cannon 202 rotates upward, the variable resistance ring on the main sliding rheostat 304, which is electrically connected to the main fan 204, moves upward, the resistance decreases, and the main fan 204 can increase its speed to ensure spray... In terms of quality, this structure is more suitable for long-distance spraying operations, ensuring sufficient dust dispersion at a distance while preventing excessive concentration of spray at close range. It eliminates the need for cumbersome relocation of the structure. When the electric push rod 302 extends or retracts, if the variable resistance ring on the main sliding rheostat 304, which is electrically connected to the electric fan 403, moves downwards and the travel is too large, causing the angle of the fog cannon 202 to be too low, the resistance of the main sliding rheostat 304 corresponding to the electric fan 403 gradually decreases. This allows the electric fan 403 to be gradually started, increasing the airflow and assisting in the outward diffusion of some of the water mist sprayed from the atomizing tube 501, thus aiding the low-speed main fan 204 in dispersing the water mist. When the swing compensation component 6 is performing compensation work, it is necessary to maintain the basic spray angle of the fog cannon 202. The tilt angle is adjusted to avoid interfering with the accuracy of the compensation wind speed, which is the normal speed of the main fan 204. The controller of the main fan 204 can also be manually adjusted to reach the basic speed. At this time, when the rotating frame 201 drives the fog cannon 202 to swing back and forth, it can drive the squeezing block 203 to squeeze the swing detection block 601 with the inclined plane, which stretches the spring on the tension spring 603. When the tension spring 603 moves, it will drive the rheostat connecting piece 605 to move the rheostat ring on the compensation sliding rheostat 604. At this time, as the squeezing block 203 swings, regardless of the direction, it will drive the resistance of the compensation sliding rheostat 604 to gradually decrease. At this time, as the swing angle gradually increases, the speed of the compensation fan 205 also gradually increases, increasing the spray distance for compensation.
