Description

Technical Field

[0001] This utility model relates to the field of fog cannon technology, and in particular to an adjustable fog cannon for construction engineering. Background Technology

[0002] During construction, a large amount of dust is inevitably generated. Existing fog cannons are basically composed of a cannon tube, a fan at the rear end of the cannon tube, and an atomizing nozzle at the front end of the cannon tube. Water is pressurized by a high-pressure pump and atomized into fine water mist through the atomizing nozzle. The fan then sprays the water mist into the air over a long distance, causing the water mist to combine with dust particles and settle, thereby achieving the purpose of dust reduction and air purification.

[0003] The dust levels vary at different locations, requiring different spray ranges from the fog cannons. While the spray range can be initially adjusted by changing the output power of the fan and high-pressure pump, the length of the cannon barrel also limits the adjustment of the spray range. Furthermore, since the cannon barrel is fixed to the fan and atomizing nozzle, it cannot be easily replaced, resulting in limited ability of the fog cannon to adjust its own spray range.

[0004] Therefore, it is necessary to propose a size-adjustable fog cannon for construction engineering to improve the fog cannon's ability to adjust the spray range. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the spray range of existing fog cannons is relatively fixed, resulting in poor adaptability. This invention provides an adjustable fog cannon for construction projects.

[0006] The technical solution of this utility model is: An adjustable fog cannon for construction engineering includes a frame and a fan, with the fan fixedly connected to the frame. It also includes a fixed frame with a nozzle fixedly connected to the fixed frame, and the fixed frame is aligned with the fan axis. A rotating frame is provided between the fixed frame and the machine frame. The rotating frame is rotatably connected to the machine frame. At least two different types of gun barrels are provided on the rotating frame, and the gun barrels are distributed in a ring around the center of the rotating frame. It also includes a drive unit that drives the rotating frame to rotate, thereby causing each gun barrel to be alternately positioned between the blower and the fixed frame.

[0007] Furthermore, a support platform corresponding to the number of gun barrels is fixedly connected to the rotating frame. Each gun barrel is slidably connected to its respective support platform. The fixed frame is slidably connected to the machine frame. The machine frame is equipped with a telescopic device. The telescopic device drives the fixed frame to move axially, thereby axially pressing and fixing the gun barrel and the blower between the fixed frame and the blower. Since the lengths of different gun barrels are different, by sliding the connection with the support platform, it can be ensured that each gun barrel can stably dock with the blower and the fixed frame, improving the compatibility of the gun barrel with the blower and the fixed frame.

[0008] Furthermore, a sliding groove is provided on the support platform, and a sliding rod parallel to the axis of the gun barrel is fixedly connected in the sliding groove. A slider is fixedly connected to the gun barrel, and the slider is slidably connected to the sliding rod. An elastic element is sleeved on the sliding rod, and the elastic element is located between the slider and the blower. The spring can provide elastic force for the gun barrel to slide relative to the support platform, so that the gun barrel always maintains the maximum distance from the blower when it is not squeezed by the fixed frame, preventing the blower from interfering with the rotation of the gun barrel when the rotating frame rotates.

[0009] Furthermore, the mounting bracket is ring-shaped.

[0010] Furthermore, the driving device is an electric motor.

[0011] Furthermore, sealing gaskets are provided at both ends of the barrel to prevent air leakage between the blower and the barrel, as well as between the barrel and the mounting bracket, thus ensuring the atomization effect.

[0012] Furthermore, the gun barrels are provided with at least three.

[0013] Furthermore, it also includes a high-pressure pump connected to the nozzle.

[0014] This utility model discloses an adjustable-size fog cannon for construction engineering, which has the following beneficial effects: The fan, cannon barrel, and nozzle are a combined structure. The rotating frame can rotate relative to the machine frame, allowing for switching between cannon barrels of different lengths between the fan and nozzle. The longer the cannon barrel, the better the wind concentration effect, resulting in a longer spray distance when the air is ejected from the cannon barrel. This allows for initial adjustment of the dust removal range of the fog cannon. In addition, the fan power is adjustable, and the atomization effect of the nozzle can be changed by the pressure of the high-pressure pump. Therefore, the spray range of the fog cannon can be further adjusted, improving its ability to adjust the spray range, optimizing its adaptability, and making it highly practical.

[0017] To make the technical means, technical features, utility model purpose and technical effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0018] Example 1: like Figure 1 and Figure 2 As shown, this embodiment provides an adjustable fog cannon for construction engineering, including a frame 1 and a fan 2. The fan 2 is fixedly connected to the frame 1 with screws. It also includes a fixing frame 3, on which a nozzle 4 is fixedly connected with screws. The fixing frame 3 is aligned with the axis of the fan 2. A rotating frame 5 is provided between the fixing frame 3 and the frame 1. The rotating frame 5 is rotatably connected to the frame 1 through a bearing. The rotating frame 5 is provided with at least two cannons 6 of different types. The cannons 6 are distributed in a ring around the center of the rotating frame 5. It also includes a driving device 15, which drives the rotating frame 5 to rotate, thereby causing each cannon 6 to be alternately placed between the fan 2 and the fixing frame 3.

[0019] Preferred, such as Figure 3 As shown, the rotating frame 5 is screwed to a support platform 7 corresponding to the number of gun barrels 6. Each gun barrel 6 is slidably connected to its respective support platform 7. The fixed frame 3 is slidably connected to the frame 1 via a guide rail. The frame 1 is screwed to install a telescopic device 8, which is preferably a pneumatic cylinder or an electric cylinder. The telescopic device 8 drives the fixed frame 3 to move axially, thereby axially pressing and fixing the gun barrels 6 and the blower 2 between the fixed frame 3 and the blower 2. Since the lengths of different gun barrels 6 are different, the distance between the gun barrels 6 and the blower 2 can be adjusted by sliding the connection with the support platform 7, thereby ensuring that each gun barrel 6 can stably dock with the blower 2 and the fixed frame 3, improving the compatibility of the gun barrels 6 with the blower 2 and the fixed frame 3.

[0020] Preferred, such as Figure 3As shown, the support platform 7 is provided with a sliding groove 9. A sliding rod 10 parallel to the axis of the gun barrel 6 is fixedly connected to the sliding groove 9 with screws. A slider 11 is fixedly connected to the gun barrel 6 with screws. The slider 11 is slidably connected to the sliding rod 10 and slides by sliding friction. An elastic element 12 is sleeved on the sliding rod 10. The elastic element 12 is preferably a spring. The elastic element 12 is located between the slider 11 and the blower 2. The spring can provide elastic force for the gun barrel 6 to slide relative to the support platform 7, so that the gun barrel 6 always maintains the maximum distance from the blower 2 when it is not squeezed by the fixed frame 3, preventing the blower 2 from falling on the rotation path of the rotating frame 5 when the rotating frame 5 rotates, and avoiding interference with the rotation of the gun barrel 6.

[0021] Preferred, such as Figure 2 As shown, the fixing frame 3 is circular. Preferably, the driving device 15 is a motor, and the motor is equipped with a limit device to prevent the rotating frame from rotating due to instability of the center of gravity when the motor stops. Preferably, sealing gaskets 13 are provided at both ends of the cannon barrel 6 to prevent air leakage between the fan 2 and the cannon barrel 6, and also to prevent air leakage between the cannon barrel 6 and the fixing frame 3, thus ensuring the atomization effect.

[0022] Preferred, such as Figure 2 As shown, there are at least three gun barrels 6, preferably three gun barrels 6. The three gun barrels 6 have different lengths, and the three barrels can form a triangle to ensure the force balance of the rotating frame 5 and ensure structural stability.

[0023] Preferred, such as Figure 1 As shown, it also includes a high-pressure pump 14 connected to the nozzle 4 and a water tank. The high-pressure pump 14 is connected to the nozzle 4 through a pipe. The high-pressure pump 14 pumps water from the water tank into the nozzle 4. The pipe can be installed inside the frame or exposed outside the frame. The specific wiring method can be selected by those skilled in the art according to the actual situation. The power of the high-pressure pump 14 is adjustable to adapt to different lengths of the cannon barrel 6 in order to achieve different atomization dust removal ranges. The fan 2 is also a power adjustable fan 2 to adapt to different models and sizes of cannon barrel 6 in order to achieve different atomization dust removal ranges.

[0024] When using, such as Figure 4 and Figure 5As shown, a suitable cannon barrel 6 is selected based on the surrounding site and the scale of dust. Then, the power of the fan 2 and the high-pressure pump 14 is adjusted according to the length and size of the selected cannon barrel 6. The drive device 15 is started, the rotating frame 5 rotates, and the target cannon barrel 6 is rotated between the fan 2 and the fixed frame 3, and the axes of the three are aligned. Then, the telescopic device 8 drives the fixed frame 3 to move axially. After the fixed frame 3 contacts one end of the cannon barrel 6, it pushes the cannon barrel 6 to move synchronously, so that the other end of the cannon barrel 6 is in contact with the fan 2. Finally, the telescopic device 8 presses and fixes the fan 2, the cannon barrel 6 and the fixed frame 3 together. Due to the presence of the sealing gasket 13, there will be no air leakage at both ends of the cannon barrel 6, which improves the air tightness and ensures the blowing force and atomization effect. Finally, the fan 2 and the high-pressure pump 14 are started. The fan 2 guides the air through the cannon barrel 6 and sprays it out, while driving the water mist at the nozzle 4 to move, so as to achieve area dust removal.

[0025] The fan 2, cannon 6, and nozzle 4 of this utility model are a combined structure. The rotating frame 5 can rotate relative to the frame 1, thereby switching between cannons 6 of different lengths between the fan 2 and the nozzle 4. The longer the cannon 6, the better the condensation effect of the wind, and the farther the water mist is sprayed, thus initially adjusting the dust removal range of the fog cannon. In addition, the power of the fan 2 is adjustable, and the atomization effect of the nozzle 4 can also be changed by the pressure of the high-pressure pump 14. Therefore, the dust removal range of the fog cannon can be further adjusted, the adaptability of the fog cannon can be optimized, and it has strong practicality.

[0026] Example 2: The similarities between this embodiment and Embodiment 1 will not be repeated here. The difference lies in that, as an optional approach, such as... Figure 6 As shown, an elevation angle adjustment device 16 can be installed at the bottom of the frame 1 of this device, thereby realizing the adjustment of the spray tilt angle of this fog cannon. The elevation angle adjustment device 16 is composed of a hydraulic cylinder or a pneumatic cylinder. This device is existing technology, and those skilled in the art can choose a suitable elevation angle adjustment device 16 themselves, which will not be described in detail here.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. All equivalent changes and modifications made in accordance with the scope of the claims of this utility model should fall within the technical scope of this utility model.
