Description

Technical Field

[0001] This utility model relates to the field of construction equipment, and in particular to a fog cannon for the construction of water diversion channels and tunnels. Background Technology

[0002] Canals and tunnels serve different functions in irrigation areas. Canals are primarily constructed using concrete pouring, with specific operational standards and procedures. For example, the timing and frequency of vibration are specified to ensure concrete density, and the number and intensity of finishing processes are standardized to achieve a smooth and even surface. The optimal curing method and time are determined based on different seasons and climatic conditions. Tunnel construction, on the other hand, requires the use of cantilever excavators. Cantilever excavators minimize disturbance to the surrounding rock, improving tunnel construction safety.

[0003] Whether it's concrete pouring for canals or tunnel excavation, construction sites generate a large amount of dust. If this dust is not treated and is directly inhaled by workers, it can affect their health. A common method used in construction is to suppress dust with mist cannons. A mist cannon is a device that turns water into a mist through a machine, used to reduce dust and haze. The mechanical principle of a mist cannon is to use a specially designed high-pressure atomization system and a double-tube annular spray ring to atomize a normal solution into water mist particles of 10 to 150 micrometers in size, with a spraying distance of up to 200 meters and a height of over 40 meters. The water mist sprayed by the mist cannon adsorbs, aggregates, and settles PM2.5 and PM10 dust particles suspended in the air, achieving the purpose of eliminating pollutants and reducing haze. During operation, the mist cannon, in conjunction with the high-speed rotating fan blades, propels the water mist from the nozzles, as shown in the mist cannon disclosed in CN211411431U. However, when the fog cannon is in an air environment with a high concentration of particulate matter, the airflow containing large particulate impurities will enter the cannon barrel due to the high-speed rotating fan blades, causing damage and wear to the fan blades and the cannon barrel, which poses a safety hazard. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a fog cannon for water diversion channel and tunnel construction, which filters the air entering the fog cannon barrel, and at the same time facilitates the disassembly, cleaning and replacement of the filter screen.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a fog cannon for water diversion channel and tunnel construction, including a cannon barrel and a water tank. The water tank is used to supply water to the atomizing nozzle at the front end of the cannon barrel. The cannon barrel is set on the water tank. A fan blade is set inside the cannon barrel. A filter mechanism is set at the tail end of the cannon barrel. The filter mechanism includes a filter screen. The filter screen has several grooves around its circumference. Insert blocks are set in the grooves. A spring is set between the insert blocks and the bottom of the grooves. The barrel wall has insertion holes corresponding to the insert blocks.

[0006] In a preferred embodiment, a rope hole is provided at the center of the filter screen, and a through hole communicating with the rope hole is provided at the bottom of the groove. One end of the insert is connected to a control rope, which passes through the through hole at the bottom of the groove and is connected to an operation rope. The operation rope passes through the rope hole.

[0007] In a preferred embodiment, the top of the water tank is provided with a rotating mechanism for horizontally rotating the barrel. The rotating mechanism includes a mounting plate that is rotatably mounted on the top of the water tank, and the mounting plate is driven by a drive mechanism.

[0009] In a preferred embodiment, the mounting plate is provided with a pitch angle adjustment mechanism for adjusting the pitch angle of the gun barrel. The pitch angle adjustment structure includes a support frame, the gun barrel is hinged to the support frame, and the mounting plate is provided with a telescopic mechanism for adjusting the pitch angle of the gun barrel.

[0010] In a preferred embodiment, the telescopic mechanism is a cylinder, with the lower end of the cylinder hinged to the mounting plate and the telescopic end hinged to the barrel.

[0011] In a preferred embodiment, the water tank is equipped with an impurity scraping mechanism, which includes a slider. The inner wall of the water tank is provided with a groove that slides and engages with the slider. A scraper is provided inside the water tank to scrape impurities from the inner wall of the water tank.

The scraper is provided with a threaded hole that engages with the screw. The screw is driven by a second motor.

[0012] In a preferred embodiment, the water tank is equipped with tracks on its outer side for the fog cannon to move.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1:

[0033] like Figures 1-6 As shown, a fog cannon for water diversion channel and tunnel construction includes a cannon barrel 100 and a water tank 200. The water tank 200 is used to supply water to the atomizing nozzle 300 at the front end of the cannon barrel 100. Specifically, the water tank 200 is provided with a water inlet and a drain outlet. The drain outlet is equipped with a solenoid valve to control the opening and closing of the drain outlet. The water tank 200 supplies water to the atomizing nozzle 300 through a water pipe and a water pump.

[0034] The cannon barrel 100 is mounted on the water tank 200. A fan blade 400 is installed inside the cannon barrel 100. A filter mechanism 500 is provided at the tail end of the cannon barrel 100. The filter mechanism 500 is located between the fan blade 400 and the tail end of the cannon barrel 100 to filter the air entering the cannon barrel 100.

[0035] Preferably, the water tank 200 is provided with tracks 1000 on its outer side for the fog cannon to move. Tracks 1000 can also be replaced by wheels.

[0036] The filter mechanism 500 includes a filter screen 510, which has several grooves 511 arranged circumferentially. In this embodiment, four sets of grooves 511 are provided. An insert block 520 is provided in each groove 511. A spring 530 is provided between the insert block 520 and the bottom of the groove 511. The two ends of the spring 530 are respectively connected to the bottom of the groove 511 and the end of the insert block 520. The barrel wall of the barrel 100 has insertion holes 110 corresponding to the insert blocks 520. When replacing the filter mechanism 500, simply press the insert block 520 to press it into the groove 511 to remove the filter screen 510. In use, under the elastic force of the spring 530, the insert block 520 is pushed outward and inserted into the insertion hole 110, thus installing the filter mechanism 500.

[0037] The filter screen 510 intercepts large particulate impurities in the air, effectively reducing their entry into the cannon barrel, lowering the risk of wear and tear on the fan blades 400 and cannon barrel 100 due to impurities, extending the service life of the fog cannon, and ensuring safe operation of the equipment. The filter mechanism 500 is designed for easy disassembly and cleaning.

[0038] Preferably, the filter screen 510 has a rope hole 512 at its center, and the bottom of the groove 511 has a through hole communicating with the rope hole 512. One end of the insert block 520 is connected to the control rope 540. After the control rope 540 passes through the through hole at the bottom of the groove 511, it is connected to the operation rope 550. That is, the ends of the four sets of control ropes 540 are connected to the operation ropes 550, and the operation ropes 550 pass out from the rope hole 512.

[0039] The insertion block 520 can be pulled by the control rope 540 and the operation rope 550, pressing the insertion block 520 into the groove 511, making it easy to remove the filter screen 510 for cleaning or replacement, thus improving maintenance efficiency.

[0040] Example 2:

[0041] Unlike Example 1, such as Figure 1 and Figures 7-8 As shown, the top of the water tank 200 is provided with a rotating mechanism 600 for horizontally rotating the barrel 100. The rotating mechanism 600 includes a mounting plate 610 rotatably mounted on the top of the water tank 200. The mounting plate 610 is driven by a driving mechanism 620. The driving mechanism 620 includes a worm gear 621 rotatably mounted on the top of the water tank 200. The mounting plate 610 is fixed on the top of the worm gear 621. The worm gear 621 meshes with a worm 622. The worm 622 is rotatably mounted on a support seat 623 on the top of the water tank 200. The worm 622 is driven by a first motor 624.

[0042] Preferably, the mounting plate 610 is provided with a pitch angle adjustment mechanism 700 for adjusting the pitch angle of the gun barrel 100. The pitch angle adjustment mechanism 700 includes a support frame 710, the gun barrel 100 is hinged to the support frame 710, and the mounting plate 610 is provided with a telescopic mechanism 720 for adjusting the pitch angle of the gun barrel 100.

[0043] In this embodiment, the telescopic mechanism 720 is a cylinder, with the lower end of the cylinder hinged to the mounting plate 610, and the telescopic end hinged to the barrel 100.

[0044] The rotating mechanism 600 enables the horizontal rotation of the barrel 100. The worm gear 621 and worm 622 in the drive mechanism 620 are driven by the first motor 624, which can precisely control the horizontal rotation of the barrel and expand the dust suppression coverage area. The pitch angle adjustment mechanism 700 uses the telescopic mechanism 720, such as a cylinder, to adjust the pitch angle of the barrel 100 to meet the dust suppression needs at different heights and positions.

[0045] When the barrel 100 needs to be oriented, the first motor 624 drives the worm gear 622 to rotate, which in turn drives the mounting plate 610 to rotate via the worm wheel 621. When the mounting plate 610 rotates, it drives the barrel 100 to rotate. The extension and retraction of the output end of the telescopic mechanism 720 drives the barrel 100 to adjust its tilt angle. Through multi-directional and multi-angle turning, it can adapt to different construction positions and improve the dust suppression range.

[0046] Example 3:

[0047] Different from Example 1, such as Figure 7 As shown in the figure, a debris removal mechanism 800 is provided inside the water tank 200. The debris removal mechanism 800 includes a slider 810. A groove 210 is provided on the inner wall of the water tank 200 to slide with the slider 810. A scraper 820 is provided inside the water tank 200. The scraper 820 scrapes debris from the inner wall of the water tank 200. The scraper 820 is connected to the slider 810. The scraper 820 is driven to move along the groove 210 by a moving drive device 830. The moving drive device 830 includes a screw 831 rotatably installed inside the water tank 200. The scraper 820 is provided with a threaded hole that mates with the screw 831. The screw 831 is driven by a second motor 832.

[0048] The water tank 200 needs to be cleaned regularly to remove impurities adhering to its inner wall. The second motor 832 starts, driving the screw 831 to rotate. Then the slider 810 moves in the slide groove 210 and moves the scraper 820. The movement of the scraper 820 removes the impurities on the inner wall, thus cleaning the water and preventing impurities in the water from clogging the atomizing nozzle. Then the drain port is opened to discharge the impurities and water together.

[0049] Preferably, a storage box 1100 is provided on the top of the water tank 200 for storing flocculant, which facilitates its addition into the water tank 200 for water treatment. During use, the flocculant in the storage box 1100 can be taken as needed and added to the water tank 200, which helps purify the water and prevents unpurified water from clogging the atomizing nozzles, thus providing protection.

[0050] Example 4:

[0051] Unlike Example 1, such as Figure 1 and Figure 7 As shown, the water tank 200 is provided with nozzle devices 900 on both sides. The nozzle device 900 includes nozzles 920 arranged on both sides of the water tank 200. The nozzles 920 are strip nozzles or multiple nozzles arranged in a row. The nozzles 920 are connected to the water pump 930 and the water tank 200 in sequence through water pipes 910.

[0052] When the concrete poured in the channel needs curing, the water pump 930 is started so that the water in the water tank 200 enters the nozzle 920 through the water pipe 910. Then the nozzle 920 sprays water onto the concrete to achieve curing.

[0053] Working Principle: This fog cannon has tracked wheels to adapt to complex terrain during hydropower development and construction. In use, the fog cannon is driven to the concrete pouring site of a channel or the excavation site of a tunnel. A high-pressure pump pressurizes the water in the water tank 200, which is then transported through pipelines to the micro-atomizing nozzles at the end of the cannon barrel 100. The fan blades 400 in the air supply system rotate at high speed, generating strong airflow and pressure, which propels the atomized water mist a considerable distance. When the water mist particles come into contact with dust particles in the air, the water mist particles, due to their near-zero surface tension and large specific surface area, can quickly adsorb the dust particles. After contact with the dust, the dust is enveloped by the water mist, increasing its weight. The water mist particles, now heavier, gradually fall under the influence of gravity and eventually settle on the ground or other object surfaces, thus achieving dust suppression.

[0054] Simultaneously, through the set rotation mechanism 600 and pitch angle adjustment mechanism 700, when the barrel 100 needs to adjust its direction, the first motor 624 drives the worm gear 622 to rotate, which in turn drives the mounting plate 610 to rotate through the worm wheel 621. When the mounting plate 610 rotates, it drives the barrel 100 to rotate. Through the extension and retraction of the extension end of the telescopic mechanism 720, the barrel 100 can achieve the adjustment of its tilt angle. Through multi-directional and multi-angle turning, it can adapt to different construction directions and improve the dust suppression range.

[0055] The filter mechanism 500 can prevent airflow containing large particulate impurities from entering the cannon barrel 100 when the fan blade 400 rotates at high speed to draw air, which is beneficial for protecting the cannon barrel 100 and the fan blade 400. When the filter screen 510 needs to be replaced, it is convenient to install and replace the filter screen. Pulling the operating rope 550 will move the insert block 520 in the groove 511 and compress the spring 530. Then the insert block 520 will retract into the groove 511. Then the filter screen 510 will be placed inside the cannon barrel 100 and the insert block 520 will be aligned with the insertion hole 110. Then the operating rope 550 will be released and the spring 530 will be reset, allowing the insert block 520 to move into the insertion hole 110, which is convenient for installing the filter screen 510. To remove it, simply pull the filter screen 510 again.

[0056] When the concrete poured in the channel needs curing, the water pump 930 is started so that the water in the water tank 200 enters the nozzle 920 through the water pipe 910. Then the nozzle 920 sprays water onto the concrete to achieve curing.

[0057] The water tank 200 needs to be cleaned regularly to remove impurities adhering to its inner wall. The second motor 832 starts, driving the screw 831 to rotate. Then the slider 810 moves in the slide groove 210 and moves the scraper 820. The movement of the scraper 820 removes the impurities on the inner wall, thus cleaning the water and preventing impurities in the water from clogging the atomizing nozzle. Then the drain port is opened to discharge the impurities and water together.
