Abstract
Description
Technical Field
[0001] This application relates to the field of fog cannons, and more particularly to a retractable fog cannon. Background Technology
[0002] A fog cannon is an environmentally friendly device used on construction sites for dust suppression, air purification, or spraying. During the concrete preparation process, a large amount of dust exists in the air, and fog cannons can reduce the spread of dust in the air.
[0003] Currently, a utility model patent with publication number CN222468485U discloses a dust suppression device for construction projects, including a housing. A cannon is installed on the top of the housing, and an inspection port is provided through one end of the cannon. A cover plate is hinged to the outside of the cannon at the inspection port, and a lever is fixed to the outside of the cover plate. A limiting component is fixed to the outside of the cannon, and the lever is detachably connected to the limiting component. The limiting component includes a block, a groove, a slot, a spring, and a first rod. The block is fixed to the outside of the cannon, and a groove is provided on one side of the block. This utility model has the effect of facilitating maintenance.
[0004] Since the cannon barrel is always located outside the housing, the fog cannon needs to be placed independently when not in use, and cannot be stacked, resulting in low space utilization and inconvenient storage. Utility Model Content
[0005] In order to improve space utilization by storing the fog cannon when not in use, this application provides a retractable fog cannon.
[0006] This application provides a retractable fog cannon, which adopts the following technical solution:
[0007] A retractable fog cannon includes a housing, a cannon barrel, a retractable assembly, a top plate, and a cover plate. The housing has an opening at the top, the cannon barrel slides vertically into the housing, the top plate is located at the opening of the housing, and the top plate has a through hole for the cannon barrel to protrude. The retractable assembly is used to move the cannon barrel out of the through hole or into the housing, and the cover plate is used to cover the through hole.
[0008] By adopting the above technical solution, when the fog cannon is in use, the retractable assembly keeps the cannon tube exposed through the opening, allowing the cannon tube to spray. When the fog cannon is no longer in use, the staff can retract the cannon tube into the box using the retractable assembly and cover the opening on the top plate with the cover plate, so that the cannon tube is no longer exposed inside the box. The staff can then stack other items on the box, thereby improving the space utilization rate of the location of the fog cannon.
[0009] Optionally, the retractable assembly includes a mounting plate and a screw. The mounting plate is slidably connected to the housing in a vertical direction. The gun barrel is disposed on the mounting plate. The length direction of the screw is parallel to the sliding direction of the mounting plate. The screw is rotatably connected to the housing. The mounting plate is screwed to the screw.
[0010] By adopting the above technical solution, when the operator needs to adjust the state of the gun barrel exposed or inserted into the housing, the operator can rotate the screw, which drives the mounting plate to move. The mounting plate slides relative to the housing, thereby adjusting the state of the gun barrel. The screw has a self-locking effect, which improves the stability of the gun barrel state.
[0011] Optionally, the folding assembly further includes several connecting rod groups and a balance platform. The several connecting rod groups are evenly distributed on the mounting plate. Each connecting rod group includes a first connecting rod and a second connecting rod. One end of the first connecting rod is rotatably connected to the mounting plate, and the other end of the first connecting rod is rotatably connected to one end of the second connecting rod. The other end of the second connecting rod is rotatably connected to the inner bottom wall of the housing. The balance platform is horizontally positioned and rotatably connected to the connection between the first connecting rod and the second connecting rod.
[0012] By adopting the above technical solution, when the height of the gun barrel is adjusted, the mounting plate slides inside the box, and the distance between the mounting plate and the bottom wall of the box changes. At this time, the first connecting rod and the second connecting rod rotate, and the included angle between the first connecting rod and the second connecting rod changes. Since the balance table is always in a horizontal state, the balance table makes the rotation angle of the first connecting rod and the second connecting rod the same, which makes the mounting plate more stable under the drive of the screw, and the structure of the folding assembly is more reasonable.
[0013] Optionally, the mounting plate is provided with a rotating frame, the gun barrel is mounted on the rotating frame, and the rotating frame is rotatably connected to the mounting plate along a vertical axis.
[0014] By adopting the above technical solution, the rotating frame can be rotatably connected to the mounting plate, which increases the turning angle of the cannon barrel and improves the spray range of the fog cannon.
[0015] Optionally, the mounting plate is provided with a damping ring to increase the friction between the rotating frame and the mounting plate.
[0016] By adopting the above technical solution, the damping ring can reduce the risk of workers accidentally touching the rotating frame, which could cause the barrel orientation to change, and the damping ring improves the reliability of the equipment.
[0017] Optionally, the rotating frame is provided with a drive component for changing the spray elevation angle of the gun barrel. The drive component includes a worm and a worm wheel. The gun barrel is rotatably connected to the rotating frame along a horizontal axis. The worm wheel is disposed on the gun barrel. The worm is rotatably connected to the rotating frame, and the worm meshes with the worm wheel.
[0018] By adopting the above technical solution, when the operator needs to adjust the elevation angle of the gun barrel, the operator can rotate the worm gear, which drives the worm wheel to rotate, and the worm wheel drives the gun barrel to rotate. The gun barrel rotates relative to the rotating frame, thus changing the elevation angle of the gun barrel. The drive component has a simple structure, and the worm gear has a self-locking effect, making the structure more reasonable.
[0019] Optionally, the housing is provided with a water supply assembly for supplying water to the gun barrel. The water supply assembly includes a water tank, a water pump, and a hose. The water tank is located inside the housing. One end of the hose is attached to the water tank, and the other end of the hose extends through the mounting plate and is attached to the gun barrel. The water pump is used to supply water from the water tank to the gun barrel.
[0020] By adopting the above technical solution, the fog cannon is used to spray water mist into the air to reduce dust dispersion. The water tank is used to store water, and the water pump supplies the water in the tank to the cannon barrel through a hose. The cannon barrel then turns the supplied water into water mist and sprays it into the air. The water supply component is set inside the tank, which can protect the water pump inside the water supply component from prolonged contact with the dusty air outside, thus extending the service life of the water pump. In addition, the fact that the water tank is located inside the tank also reduces the contact between the water in the tank and the dust, reducing the possibility of dust entering the hose and causing blockage.
[0021] Optionally, the top plate is rotatably connected to the opening of the box, and a limiting block is provided on the inner side wall of the box to restrict the rotation of the top plate inside the box.
[0022] By adopting the above technical solution, when the water tank needs to be filled with water, the staff can rotate the top plate to expose the water tank, making it easier for the staff to add water into the tank. After the water is added, the staff rotates the top plate to abut against the limiting block, which provides support for the top plate.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. The cannon barrel can slide vertically onto the housing via a retractable assembly, allowing the cannon barrel to be retracted into the housing or exposed within the housing. When retracted into the housing, it facilitates the stacking of items on the fog cannon, improving space utilization.
[0025] 2. The rotating bracket is rotatably connected to the mounting plate, realizing the rotation of the gun barrel. The elevation angle of the gun barrel can be adjusted through the driving component, thereby improving the spray range of the gun barrel.
[0026] 3. The water supply assembly is used to supply water to the gun barrel, and the top plate is rotatably connected to the box body to facilitate the addition of water to the water tank. Attached Figure Description
