Description

Technical Field

[0001] This utility model relates to the field of dust suppression equipment technology, specifically a spray dust suppression device for construction sites. Background Technology

[0002] During construction, dust pollution at construction sites has always been a key focus of environmental protection. Existing dust suppression spray devices achieve dust settling by atomizing water with dust cannons, but in practical applications, the following technical defects still exist: In severe weather (such as strong winds), dust and particulate matter in the air are easily carried by the airflow to directly impact the atomizing nozzles of the dust suppression cannons, which not only causes dust to clog the nozzles, but may also cause nozzle wear due to particulate friction, reducing dust suppression efficiency and increasing equipment maintenance costs. For example, traditional dust suppression cannons lack effective airflow guidance and dust separation structures, and cannot pre-treat the air under wind, causing dust to directly enter the nozzles. According to statistics, the nozzle clogging frequency of such equipment is about 40% higher in windy and sandy weather than in normal environments. Therefore, this utility model provides a dust suppression spray device for construction sites to solve the above-mentioned problems. Utility Model Content

[0003] The purpose of this invention is to provide a spray dust suppression device for construction sites to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A dust suppression spray device for construction sites includes a base and a water bucket. A fixing frame is installed on the upper surface of the base, and a support plate is installed inside the fixing frame. A dust suppression component for separating dust from the air is installed at the upper end of the support plate. A cleaning mechanism for cleaning the buildings and roads on both sides of the base is installed at the rear end of the fixing frame. A protective component for separating dust entering the dust suppression component is snapped into the interior of the dust suppression component. A positioning mechanism for positioning the water bucket is installed on the upper surface of the base. A reset component for slowly resetting the protective component is installed on the outer surface of the protective component. The dust suppression component includes a dust suppression cannon.

[0006] As a further embodiment of this utility model, the protective component includes a fixed ring, which is snapped into the interior of the dust suppression cannon. Multiple sets of racks are slidably connected inside the fixed ring. A guide plate is installed on the outer surface of the racks. A positioning block is installed on the inner wall of the fixed ring. A rotating rod is rotatably connected inside the positioning block. An airflow guide plate and a gear are installed at the outer end of the rotating rod. The gear and the rack are meshed together.

[0007] As a further embodiment of this utility model, the cleaning mechanism includes a first water pump, which is installed on the upper surface of the base. A first conduit is installed at the water inlet end of the first water pump, a second conduit is installed at the water outlet end of the first water pump, and a drain pipe is installed at the water outlet end of the second conduit. The drain pipe is installed on the upper surface of the base, and multiple sets of valves are installed on the outer surface of the drain pipe. A first nozzle, a second nozzle, and a third nozzle are respectively installed at the outer end of the drain pipe.

[0008] As a further embodiment of this utility model, the positioning mechanism includes a positioning seat, which is installed on the upper surface of the base. An arc-shaped limiting plate is slidably connected to the upper surface of the positioning seat, and the inner walls of the two sets of arc-shaped limiting plates respectively abut against the left and right sides of the water bucket.

[0009] As a further embodiment of this utility model, the reset component includes an anemometer, which is installed on the upper surface of the dust suppression cannon. An electromagnetic block is installed inside the rack, and the side of the electromagnetic block away from the rack is adsorbed inside the fixed ring. The control terminals of the anemometer and the electromagnetic block are electrically connected.

[0010] As a further improvement of this invention, the outer surface of the protective component is coated with anti-rust paint.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In use, this utility model involves pushing a fixed ring to engage it inside the dust suppression cannon, adjusting the positions of multiple airflow guide plates to align with the parallel positions of multiple atomizing nozzles. Then, wind power drives the guide plates to slide the rack within the slot of the fixed ring. During this sliding motion, the rack drives the gear to rotate, adjusting it to a perpendicular position inside the fixed ring. This guides the airflow to form a cyclone separation or inertial separation effect, separating dust from the air. This prevents dust and particulate matter from being blown into the atomizing nozzles of the dust suppression cannon during severe weather, thus improving the stability of the dust suppression cannon during use.

[0013] 2. When using this utility model, the first water pump is started by operating the electrical control box, which guides the water inside the water tank into the drain pipe along the first and second conduits. Then, the water flows through the multiple sets of drain holes in the drain pipe, which are installed with the first, second, and third nozzles respectively. This allows the water to be discharged through the first, second, and third nozzles after entering the drain pipe. As a result, the device can simultaneously clean the buildings or equipment on both sides of the base during the dust suppression process, thereby expanding the scope of application of the device and improving its practicality.

[0019] 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.

[0020] Please see Figures 1-4In this embodiment of the present invention, a dust suppression spray device for construction sites includes a base 1 and a water bucket 4. A fixing frame 2 is installed on the upper surface of the base 1, and a support plate 5 is installed inside the fixing frame 2. A dust suppression component for separating dust from the air is installed at the upper end of the support plate 5. A cleaning mechanism 7 for cleaning the buildings and roads on both sides of the base 1 is installed at the rear end of the fixing frame 2. A protective component for separating dust entering the dust suppression component is snapped into the interior of the dust suppression component. A positioning mechanism 3 for positioning the water bucket 4 is installed on the upper surface of the base 1. The outer surface is equipped with a slow reset protection component. The dust suppression component includes a dust suppression cannon 6, which is installed on the upper surface of the fixed frame 2. The upper surface of the support plate 5 is equipped with a second water pump 10 and an electrical control box 11. The water inlet end of the second water pump 10 is equipped with a first connecting pipe 9, which passes through the top water inlet of the water tank 4 and is inserted into the inside of the water tank 4. The drain end of the second water pump 10 is equipped with a second connecting pipe 13, which is installed inside the water inlet of the dust suppression cannon 6. The dust suppression cannon 6 includes multiple sets of atomizing nozzles.

[0021] Specifically, by adjusting the wind-driven protective component to a position parallel to the atomizing nozzle inside the dust suppression cannon 6, the protective component not only shields and protects the nozzle but also guides the airflow to form a cyclone separation or inertial separation effect to separate dust in the air. This prevents dust and particulate matter from being blown into the atomizing nozzle of the dust suppression cannon 6 during severe weather, thus avoiding damage to the dust suppression cannon 6 and improving its stability during use.

[0022] The protective assembly includes a fixed ring 1201, which is snapped into the interior of the dust cannon 6. Multiple sets of racks 1207 are slidably connected inside the fixed ring 1201. A guide plate 1202 is mounted on the outer surface of each rack 1207. A positioning block 1204 is mounted on the inner wall of the fixed ring 1201. A rotating rod 1205 is rotatably connected inside the positioning block 1204. An airflow guide plate 1203 and a gear 1206 are mounted on the outer end of the rotating rod 1205. The rack 1207 and the fixed ring 1201 are meshed together. The fixed ring 1201 has a groove inside. The rack 1207 is slidably connected inside the groove of the fixed ring 1201. The positioning block 1204 has a groove inside. The rotating rod 1205 is rotatably connected inside the groove of the positioning block 1204. A spring 1208 is installed on the inner wall of the groove of the fixed ring 1201. The end of the spring 1208 away from the inner wall of the groove of the fixed ring 1201 is installed on the back of the rack 1207.

[0023] Specifically, by pushing the fixed ring 1201, the fixed ring 1201 is engaged inside the dust suppression cannon 6, adjusting the position of multiple airflow guide plates 1203 to one side parallel to the multiple atomizing nozzles. Then, the wind-driven guide plate 1202 drives the rack 1207 to slide inside the slot of the fixed ring 1201, causing the rack 1207 to drive the gear 1206 to rotate during the sliding process. This causes the gear 1206 to adjust to a position perpendicular to the inside of the fixed ring 1201 during rotation, thereby guiding the airflow to form cyclone separation or inertial separation. The separation effect separates dust in the air, thus preventing dust and particulate matter from being blown into the atomizing nozzle of the dust suppression cannon 6 during severe weather and causing damage to the dust suppression cannon 6, thereby improving the stability of the dust suppression cannon 6 during use; a spring 1208 is installed at one end of the rack 1207, so that the rack 1207 compresses the spring 1208 during sliding. Conversely, when the wind speed decreases to the point that it cannot push the guide plate 1202 to move, the spring 1208 uses its own retraction property to push the rack 1207 to drive the guide plate 1202 and the airflow guide plate 1203 to automatically reset.

[0024] The cleaning mechanism 7 includes a first water pump 702, which is installed on the upper surface of the base 1. A first conduit 701 is installed at the water inlet end of the first water pump 702, a second conduit 703 is installed at the water outlet end of the first water pump 702, and a drain pipe 704 is installed at the water outlet end of the second conduit 703. The drain pipe 704 is installed on the upper surface of the base 1, and multiple sets of valves 705 are installed on the outer surface of the drain pipe 704. A first nozzle 706, a second nozzle 707, and a third nozzle 708 are respectively installed at the outer end of the drain pipe 704. Multiple sets of drain holes are opened at the outer end of the drain pipe 704. The first nozzle 706, the second nozzle 707, and the third nozzle 708 are respectively installed inside the multiple sets of drain holes of the drain pipe 704. The electrical control box 11 and the control terminal of the first water pump 702 are electrically connected. A through hole is opened on the side of the water tank 4 near the fixed frame 2, and the water inlet end of the first conduit 701 is installed inside the through hole of the water tank 4.

[0025] Specifically, by controlling the electrical control box 11 to start the first water pump 702, the water inside the water tank 4 is guided into the drain pipe 704 along the first conduit 701 and the second conduit 703. Then, the water is discharged through the first nozzle 706, the second nozzle 707 and the third nozzle 708 installed in the multiple sets of drain holes of the drain pipe 704. This allows the water to be guided into the drain pipe 704 and then discharged through the first nozzle 706, the second nozzle 707 and the third nozzle 708. In this way, the device can simultaneously clean the buildings or equipment on both sides of the base 1 during the dust suppression process, thereby expanding the scope of application of the device and improving its practicality.

[0026] The positioning mechanism 3 includes a positioning seat 301, which is installed on the upper surface of the base 1. An arc-shaped limiting plate 302 is slidably connected to the upper surface of the positioning seat 301. The inner walls of the two sets of arc-shaped limiting plates 302 respectively abut against the left and right sides of the water bucket 4. Two sets of slots are opened on the upper surface of the positioning seat 301. The arc-shaped limiting plate 302 is slidably connected inside the slots of the positioning seat 301. An arc-shaped groove is opened on the upper surface of the positioning seat 301. The inner contour of the arc-shaped groove matches the outer contour of the water bucket 4.

[0027] Specifically, by moving the water bucket 4, it is snapped into the arc-shaped groove of the positioning seat 301. Then, by pushing the two sets of arc-shaped limiting plates 302, the two sets of arc-shaped limiting plates 302 are respectively installed into the two sets of slots of the positioning seat 301, so that the inner walls of the two sets of arc-shaped limiting plates 302 abut against the left and right sides of the water bucket 4, thereby restricting the movement of the water bucket 4 on the upper end of the base 1 by the positioning mechanism 3. This prevents the water bucket 4 from wobbling left and right after the device is installed on the upper end of the cleaning cart, thus improving the safety of the device during use. By pushing the arc-shaped limiting plates 302, the arc-shaped limiting plates 302 are removed from the slots of the positioning seat 301, so that the arc-shaped limiting plates 302 can be disassembled, thereby preventing the arc-shaped limiting plates 302 from hindering the staff from disassembling the moving water bucket 4.

[0028] The reset assembly includes an anemometer 801, which is mounted on the upper surface of the dust cannon 6. An electromagnetic block 802 is installed inside the rack 1207. The side of the electromagnetic block 802 away from the rack 1207 is attached to the inside of the fixing ring 1201. The control terminals of the anemometer 801 and the electromagnetic block 802 are electrically connected. The control box 11 is electrically connected to the control terminal of the anemometer 801. Grooves are provided on both sides of the rack 1207 near the slot of the fixing ring 1201. The electromagnetic block 802 is installed inside the groove of the rack 1207.

[0029] Specifically, the anemometer 801 is activated and deactivated by the electromagnetic block 802. When the wind force drops to level three or below, the anemometer 801 is activated and the electromagnetic block 802 is activated. During the activation process, the electromagnetic block 802 is magnetically attracted to the inner wall of the slot of the fixed ring 1201. When the spring 1208 pushes the rack 1207 to slide using its own retraction characteristic, the electromagnetic block 802 uses its own magnetic attraction to slow down the reset sliding speed of the rack 1207 inside the slot of the fixed ring 1201. This prevents the rack 1207 from quickly resetting and causing the spring 1208 to rebound, which could damage the internal equipment of the protective component due to high-frequency vibration. Therefore, the service life of the protective component is improved.

[0030] The outer surface of the protective component is coated with anti-rust paint; specifically, the anti-rust paint is sprayed onto the outer surface of the protective component, so that the anti-rust paint covers the outer surface of the protective component, thereby preventing the protective component from rusting during long-term contact with water vapor and water flow, thus improving the service life of the protective component.

[0031] The working principle of this utility model is as follows:

[0032] When this utility model is in use, the fixed ring 1201 is pushed and engaged inside the dust suppression cannon 6, so that the initial position of the multiple airflow guide plates 1203 is parallel to the atomizing nozzle. When the wind drives the guide plate 1202, it drives the rack 1207 to slide in the slot of the fixed ring 1201. The rack 1207 drives the gear 1206 to rotate, so that the gear 1206 adjusts the airflow guide plate 1203 to a vertical position inside the fixed ring 1201, forming a cyclone separation or inertial separation effect to separate dust in the air. The control box 11 starts the first water pump 702, which guides the water in the water tank 4 through the first conduit 701 and the second conduit 703 into the drain pipe 704. The multiple drain holes of the drain pipe 704 are respectively installed with the first nozzle 706, the second nozzle 707 and the third nozzle 708. After the water flows out through the nozzles, it cleans the buildings or equipment on both sides of the base 1 while suppressing dust.

[0033] Meanwhile, the anemometer 801 monitors the wind force level in real time. When the wind force is less than or equal to level three, the electromagnetic block 802 is triggered to open. The electromagnetic block 802 is magnetically attracted to the inner wall of the slot of the fixed ring 1201. At this time, when the spring 1208 pushes the rack 1207 to reset and slide, the electromagnetic block 802 uses magnetic attraction to slow down the sliding speed of the rack 1207, so as to prevent the rack 1207 from quickly resetting and causing the spring 1208 to rebound.

[0034] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
