Description

Technical Field

[0001] The invention relates to the technical field of dust reduction equipment, in particular to dust reduction equipment for construction engineering. Background Art

[0002] During the construction process, in order to ensure the surrounding air quality and the health of construction workers, dust reduction equipment is usually required to be installed at the construction site. The cannon fog machine is the most frequently used dust reduction equipment. The fan installed inside can make the water mist spread over a long distance. That is, as the water mist is sprayed into the air, the dust in the air will fall due to the attachment to the water mist, so as to ensure sufficient dust reduction on the construction site.

[0003] At present, a patent with announcement number CN112974032B discloses a fog cannon, comprising: a fog cannon duct, used to provide an air flow channel; a duct fan, fixedly arranged inside the fog cannon duct and used to provide high-pressure airflow; an inner cone barrel, fixedly arranged on one side of the air outlet end of the fog cannon duct and used to reduce the caliber of the air flow channel to increase the air flow pressure; wherein, the outer wall of the inner cone barrel is provided with an outer cone arc plate which can slide along the generatrix direction of the inner cone barrel to adjust the caliber of the air flow channel, and the end portion of the outer cone arc plate is fixedly provided with a high-pressure nozzle for spraying mist droplets. By arranging an outer cone arc plate outside the inner cone barrel, the outer cone arc plate can be pushed forward to form a new hollow frustum cylinder outside the inner cone barrel, and the diameter of the frustum cylinder is further reduced. Therefore, when the airflow passes through the hollow frustum cylinder with a smaller diameter formed by the outer cone arc plate, the pressure of the airflow is greater, and the positions of the high-pressure nozzles are closer, and the formed fog group is more compact, so the airflow can drive the fog group to fly a farther distance, thereby increasing the range of the fog cannon machine. Without increasing the power of the fan, the range of the fog cannon machine is increased, and the adjustment method is more economical and practical.

[0004] However, the following problems still exist in the current use of fog cannons:

[0005] The above-mentioned device changes the range of the cannon fog machine by changing the air outlet diameter when in use, but because it can only be adjusted to two degrees during use, that is, either the outer cone arc plate is completely retracted or the outer cone arc plate is completely pushed out, it is impossible to perform multi-level adjustment according to different range requirements, and the use range of the device is very limited. Summary of the invention

[0031] The receiving assembly 4 includes a mounting rod 401, a guide rod 402 and a water collecting plate 403. The middle position of the mounting rod 401 is in contact with the output hose 2, and the mounting rod 401 is fixedly connected to the inner surface of the first air duct 5. The water collecting plate 403 is connected to the output hose 2, and the guide rod 402 is fixedly installed on the water collecting plate 403.

[0032] The connecting assembly 7 includes a support plate 701, a connecting hose 702 and a lifting plate 703.

[0034] When it is necessary to reduce dust on the construction site, water can be added to the storage water tank 1 through the water inlet pipe arranged on the left side of the storage water tank 1, and the water pump arranged inside the storage water tank 1 is installed on the output hose 2. At this time, the water in the storage water tank 1 can be pumped out through the water pump (the output hose 2 is set as a PVC soft water pipe, and a corrugated water pipe is arranged on the left side of the output hose 2 to ensure the elongation of the output hose 2). At this time, the water entering the output hose 2 can enter the connecting hose 702 through the water collecting plate 403 (the material of the connecting hose 702 and the output hose 2 is set to be the same). At this time, the water in the connecting hose 702 is sprayed out through the fixed nozzle 8, and then the fan arranged on the left side of the first wind tube 5 starts to work, that is, the fan starts to work to generate wind, and the wind starts to push the water mist, so that the water mist is sprayed out of the cannon fog machine. As the extension arc plate 13 moves to the right, the extension arc plate 13 starts The upper end of the lifting plate 703 is pressed, and the connecting slide rod 902 installed on the second fixed plate 903 begins to slide in the through groove opened on the first fixed plate 901, and the connecting spring 904 begins to be squeezed and deformed, that is, under the action of the connecting spring 904, the lifting plate 703 can be effectively guaranteed to move with the movement of the extended arc plate 13 (the lifting plate 703 is fixedly installed on the extended arc plate 13), ensuring that the distance between the fixed nozzle 8 and the extended arc plate 13 remains unchanged, that is, the fixed nozzle 8 is always in the edge position, effectively avoiding the waste of wind power (when the fixed nozzle 8 is not in the edge position, the wind passing through the edge position will not contact the water mist), and with the movement of the extended arc plate 13, the water collecting plate 403 also begins to move to the right, that is, the guide rod 402 begins to slide on the mounting rod 401, so as to achieve the purpose of always supporting the lifting plate 703.

[0035] The limiting assembly 12 includes a connecting ball 121 and a limiting plate 122, and the connecting ball 121 is fixedly mounted on the first telescopic rod 11, and the limiting plate 122 is fixedly mounted on the outer surface of the extending arc plate 13, and a guide groove is opened on the limiting plate 122, and the connecting ball 121 forms a sliding connection with the limiting plate 122 through the guide groove opened on the limiting plate 122.

[0036] The extended arc plate 13 is configured as an arc plate structure, and there are eight extended arc plates 13 in total, and the extended arc plate 13 is combined with the outer surface of the second air duct 6, and the two extended arc plates 13 are connected by a connecting arc pad 14, and the connecting arc pad 14 is configured to be an elastic arc rubber material; a guide slider 15 is installed on the outer surface of the second air duct 6, and the outer surface of the guide slider 15 is configured to be smooth, a long strip groove is provided on the inner surface of the extended arc plate 13, and the guide slider 15 is slidably connected to the extended arc plate 13 through the groove provided on the extended arc plate 13.

[0037] The electrorheological fluid groove 18 is configured as a long strip groove, and the inner surface of the electrorheological fluid groove 18 is configured as a matte surface.

[0038] When the range needs to be changed by changing the air outlet diameter (the air pressure starts to increase as the diameter decreases), the first telescopic rod 11 starts to work, because the first telescopic rod 11 is equipped with a connecting ball 121. At this time, the connecting ball 121 starts to slide in the limiting plate 122, that is, the extension arc plate 13 connected to the limiting plate 122 starts to move to the right (the extension arc plates 13 are connected in pairs through the connecting arc pads 14, and the connecting arc pads 14 are made of elastic rubber. When the extension arc plates 13 are retracted, the connecting arc pads 14 are in a stretched state). As the extension arc plates 13 are pushed out, the connecting arc pads 14 are in a stretched state. The arc pad 14 begins to recover its deformation, pulling the extended arc plate 13 to move in the direction of approaching each other. Under the action of the guide slider 15, the extended arc plate 13 can be limited to ensure the stability of the extended arc plate 13 when moving. Then the connecting wire 17 is connected to the external power supply (the connecting wire 17 and the external power supply form an electrical connection). Because the connecting wire 17 is connected to the energized coil 16, the energized coil 16 begins to be energized, thereby generating an electric field. Under the action of the electric field, the electrorheological fluid set in the electrorheological fluid groove 18 on the connecting arc pad 14 begins to become solid. (The electrorheological fluid is a suspension under normal conditions, which can undergo a liquid-solid transformation under the action of an electric field. When the strength of the applied electric field is much lower than a certain critical value, the electrorheological fluid is in liquid state; when the electric field strength is much higher than this critical value, it becomes solid.) At this time, under the action of the solid electrorheological fluid, the extended arc plates 13 can be connected and supported in pairs, ensuring the stable connection effect of the extended arc plates 13, avoiding the movement and deformation of the extended arc plates 13 due to the impact of airflow during subsequent use, ensuring the stability of the extended arc plates 13 during air conduction, and when the extended arc plates need to be adjusted When 13 moves, the connecting wire 17 is powered off. At this time, the electrorheological fluid is in liquid state, that is, it is no longer fixed in pairs with the extension arc plate 13, ensuring the smooth movement of the subsequent extension arc plate 13. When not in use, the first telescopic rod 11 starts to work, driving the extension arc plate 13 to retract. At this time, the connecting arc pad 14 is stretched and deformed. As the extension arc plate 13 is retracted, the extension arc plate 13 and the connecting arc pad 14 can be protected by the protective jacket 10 to prevent the extension arc plate 13 and the connecting arc pad 14 from being directly exposed to the air for a long time, causing deformation and aging, thereby improving the service life of the device.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
