Description

Technical Field

[0001] The utility model relates to the field of fog guns, in particular to a fog gun for municipal road construction. Background Art

[0002] A fog gun is an efficient dust suppression device. It atomizes water through high pressure to form fine water mist particles, which can effectively adsorb dust particles in the air and make them settle under the action of gravity, thus achieving the effects of rapid dust suppression and dust reduction. Fog guns are widely used in mines, construction sites, ports, urban roads and other places for controlling dust, improving air quality and cooling down, etc.

[0003] When the fog gun is working, although the gun barrel can be turned to change the spraying direction of the water mist, due to physical limitations, the water mist sprayed by the fog gun at any given time point is still concentrated in a relatively narrow fan-shaped area. Therefore, it is impossible to achieve completely continuous and uninterrupted water mist delivery to every area within a large angle range, and thus the dust suppression effect may be uneven.

[0004] Therefore, aiming at the problem that the water mist sprayed by the existing fog gun is concentrated in a relatively narrow fan-shaped area, and it is impossible to uniformly and uninterruptedly deliver water mist to the areas within a large angle range, and thus the dust suppression effect may be uneven, a fog gun for municipal road construction can be designed to solve the above problems. Summary of the Utility Model

[0005] In order to overcome the situation that during the operation of the fog gun, due to physical limitations, the water mist sprayed by the fog gun at any given time point is still concentrated in a relatively narrow fan-shaped area. Although the gun barrel can be turned to change the spraying direction of the water mist, it is still impossible to achieve completely continuous and uninterrupted water mist delivery to every area within a large angle range, and thus the dust suppression effect may be uneven.

[0006] The technical solution of the utility model is: a fog gun for municipal road construction, which includes a main frame, a lifting drive assembly and a wide-angle spraying assembly; a lifting drive assembly is fixedly connected to the upper end of the main frame; the lifting drive assembly includes four clamping blocks; a toothed ring is rotatably connected to the inner side of the clamping blocks; four internal gears are meshed with the inner side of the toothed ring; threaded shafts are fixedly connected to the internal gears, and the threaded shafts are rotatably connected to the main frame; the upper ends of the threaded shafts are jointly rotatably connected to a sliding ring.

[0007] Preferably, the toothed ring is rotated by a motor and an external gear, and then the four internal gears and the threaded shafts are rotated together by the toothed ring, so that four internal threaded sleeves fixedly connected to the gun barrel are lifted together to complete the height adjustment of the gun barrel.

[0008] Preferably, an external gear is meshed with the outer side of the gear ring; the lower end of the external gear is rotatably connected to a motor through a rotating shaft, and the motor is fixedly connected to the main frame; internal thread sleeves are in clearance fit with the threaded shafts; a gun barrel is fixedly connected to the inner sides of the internal thread sleeves together; a wide-angle spray assembly is fixedly connected to the lower end of the gun barrel; the wide-angle spray assembly includes four feet.

[0009] Preferably, a first curved surface is formed at the upper end of the gun barrel; a cover plate is arranged at the upper end of the first curved surface, and the cover plate is fixedly connected to the gun barrel through a connecting rod; a second curved surface is formed on the lower end surface of the cover plate.

[0010] Preferably, the shapes of the first curved surface and the second curved surface are both lower near the center of the gun barrel and higher near the outer side of the gun barrel.

[0011] Preferably, a blower is installed inside the gun barrel; a fan blade is rotatably connected to the upper end of the blower through a rotating shaft.

[0012] Preferably, a high-pressure pump is arranged at the rear end of the gun barrel, and the high-pressure pump is fixedly connected to the main frame; a water tank is arranged at the lower end of the high-pressure pump, and the water tank is arranged inside the main frame. The high-pressure pump pumps the water in the water tank and sends the water into the atomizing nozzle after pressurization, so that the water is sprayed out of the atomizing nozzle in a mist state. At the same time, the blower drives the fan blade to rotate to extract the air at the lower end of the gun barrel and convey the air upward. When the air flows upward, it is blocked by the cover plate, and is evenly dispersed around under the guidance of the first curved surface and the second curved surface. Moreover, the arrangement of the first curved surface and the second curved surface can reduce the energy loss when the air turns, so that the airflow distributed around carries the water mist sprayed out of the atomizing nozzle and is evenly dispersed around to increase the dust suppression effect.

[0013] Preferably, atomizing nozzles are installed on the outer side of the gun barrel; the atomizing nozzles are communicated with the high-pressure pump through water pipes; the high-pressure pump is communicated with the water tank through water pipes.

[0014] The beneficial effects of the utility model are as follows:

[0015] 1. By arranging the lifting drive assembly and the wide-angle spray assembly, the airflow blown out of the fog cannon machine can be distributed around at the same time, and carries the water mist sprayed out of the atomizing nozzle and is evenly dispersed around to increase the dust suppression effect, and the conveying height of the water mist can be flexibly adjusted to improve the use experience;

[0016] 2. The high-pressure pump extracts water from the water tank, pressurizes it, and then sends the water into the atomizing nozzle, so that the water sprays out from the atomizing nozzle in a mist state. At the same time, the fan is driven by the motor to rotate the fan blades, so as to extract the air at the lower end of the barrel and convey the air upward. When the air flows upward, it is blocked by the cover plate, and under the guidance of the first curved surface and the second curved surface, it is evenly dispersed around. Moreover, the openings of the first curved surface and the second curved surface can reduce the energy loss when the wind turns, so that the airflow distributed around carries the water mist sprayed out from the atomizing nozzle and evenly spreads around, thereby increasing the dust suppression effect.

[0017] 3. The motor and the external gear are used to rotate the toothed ring, and then the toothed ring makes the four internal gears and the threaded shaft rotate together, so that the four internal threaded sleeves fixed to the barrel are lifted and lowered together to complete the height adjustment of the barrel, so that the conveying height of the water mist can be flexibly adjusted to improve the use experience.

Moreover, the openings of the first curved surface 602 and the second curved surface 604 can reduce the energy loss when the wind turns, so that the airflow distributed around carries the water mist ejected from the atomizing nozzle 8 and is evenly dispersed around to increase the dust suppression effect.

[0029] Through the above steps, by setting the lifting drive assembly and the wide-angle spray assembly, the airflow blown out of the fog cannon machine can be distributed around at the same time, and carry the water mist ejected from the atomizing nozzle 8 and be evenly dispersed around to increase the dust suppression effect, and the conveying height of the water mist can be flexibly adjusted to improve the use experience.
