Description

Technical Field

[0001] This utility model belongs to the technical field of spray equipment, specifically relating to an air pollution control spray equipment. Background Technology

[0002] Construction sites typically generate a large amount of dust during operations, impacting the surrounding environment. Therefore, sprinkler systems are often installed on the walls of construction sites to spray water droplets into the air to suppress dust. However, existing sprinkler systems often involve running water pipes along the walls and connecting them directly to the water supply pipes. Spraying is then done by installing nozzles on the water pipes. Because the nozzles are oriented in a fixed direction and the water flow remains constant, the sprinkler system is prone to poor performance when the wind direction changes. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide an air pollution control spray device to solve the problems mentioned in the background art.

[0004] The technical solution adopted by this air pollution control spray equipment to solve its technical problems is as follows:

[0005] An air pollution control spraying device is provided, including a left electric lifting rod and a right electric lifting rod. A motor is fixedly installed on the left electric lifting rod, and one end of a water pipe is fixedly connected to the output shaft of the motor. A water supply device is provided on the water pipe. A shaft seat is fixedly installed on the right electric lifting rod, and the other end of the water pipe is rotatably installed on the shaft seat. Several spray heads are evenly fixedly installed on the water pipe.

[0006] Furthermore, the water supply equipment includes a hollow collar fitted onto a water pipe. The two sides of the hollow collar are rotatably connected to the outer circumference of the water pipe through sealed bearings. A water supply pipe is fixedly connected to the hollow collar, and several water inlet holes are opened on the water pipe located inside the hollow collar.

[0007] Furthermore, the water supply pipe is a plastic flexible hose.

[0008] Furthermore, the nozzle is equipped with a gate inside, which is fitted to the water inlet side of the nozzle, and guide gate seats are fixedly installed on the water pipe on both sides of the gate.

[0009] Furthermore, a movable rod is provided in the middle of the water pipe, and waterproof electric telescopic rods are fixedly installed at both ends of the movable rod. The waterproof electric telescopic rods are fixedly installed on the water pipe, and several connecting blocks are fixedly installed on the movable rod. The connecting blocks are fixedly connected to the corresponding gates.

[0010] Furthermore, the bottom of both the left and right electric lifting rods is fixedly mounted with a base.

[0011] Furthermore, the base is provided with several fixing bolts.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model illustrates an air pollution control spraying device. In use, multiple units of this device are sequentially installed next to a construction site wall panel, with the water pipe positioned above the wall. When the wind direction above the device is from outside the construction site to inside, the water pipe is flush against the wall, and a motor controls the pipe to rotate so that the nozzles face upwards. This allows water droplets to enter the construction site with the wind and fall onto the ground, reducing surface dust and lowering dust levels. When the wind direction above the device is from inside the construction site to outside, the left and right electric lifting rods are raised synchronously, while the motor rotates. The spray angle of the nozzles is adjusted according to the height of the rising dust, ensuring that dust carried by the wind over the wall is captured by the sprayed droplets, achieving a good spraying effect. This device allows for convenient adjustment of the spray direction and position according to different wind directions.

[0014] 2. In the example of the air pollution control spraying device of this utility model, when in use, the hollow collar can rotate along the water pipe, and the water supply pipe can supply water into the hollow collar and enter the water pipe through the water inlet hole to complete the water supply to the inside of the water pipe.

[0015] 3. An example of the air pollution control spraying equipment of this utility model uses a plastic hose to allow for the length required for the water pipe to rise, which facilitates water supply to the water pipe.

[0016] 4. An example of this utility model is an air pollution control spray device, which can conveniently control the water flow of the spray head through a gate.

[0017] 5. In the example of this utility model, an air pollution control spraying device can adjust the position of the gate and thus the water flow rate of the spray head by controlling the synchronous extension and retraction of the waterproof electric telescopic rods on both sides.

[0018] 6. The air pollution control spraying device of this utility model can be easily supported by the base.

[0019] 7. An example of the air pollution control spraying equipment of this utility model can easily fix the base to the ground by means of fixing bolts. Attached Figure Description

[0025] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] Example 1:

[0028] like Figures 1-3 As shown, this embodiment provides an air pollution control spraying device, including a left electric lifting rod 1 and a right electric lifting rod 2. A motor 3 is fixedly installed on the left electric lifting rod 1, and one end of a water pipe 4 is fixedly connected to the output shaft of the motor 3. A water supply device is provided on the water pipe 4. A bearing seat 5 is fixedly installed on the right electric lifting rod 2, and the other end of the water pipe 4 is rotatably installed on the bearing seat 5. Several nozzles 6 are evenly fixedly installed on the water pipe 4.

[0029] In this embodiment, the water supply equipment includes a hollow collar 7 fitted on a water pipe 4. The two sides of the hollow collar 7 are rotatably connected to the outer periphery of the water pipe 4 through sealed bearings 8. A water supply pipe 9 is fixedly connected to the hollow collar 7. Several water inlet holes 10 are opened on the water pipe 4 located inside the hollow collar 7.

[0030] In this embodiment, the water supply pipe 9 is a plastic flexible hose.

[0031] In this embodiment, the nozzle 6 is provided with a gate 11 inside, the gate 11 is attached to the water inlet side of the nozzle 6, and guide gate seats 12 are fixedly installed on the water pipe 4 on both sides of the gate 11.

[0032] In this embodiment, a movable rod 13 is provided in the middle of the water pipe 4. Waterproof electric telescopic rods 14 are fixedly installed at both ends of the movable rod 13. The waterproof electric telescopic rods 14 are fixedly installed on the water pipe 4. Several connecting blocks 15 are fixedly installed on the movable rod 13. The connecting blocks 15 are fixedly connected to the corresponding gates 11.

[0033] In this embodiment, the bottom of both the left electric lifting rod 1 and the right electric lifting rod 2 are fixedly mounted with bases 16.

[0034] In this embodiment, the base 16 is provided with several fixing bolts 17.

[0035] The left and right electric lifting rods 1 and 2, as well as the two waterproof electric telescopic rods 14 in this device, are all controlled by a Siemens S7-1200 PLC. Precise synchronous extension and retraction are achieved through the PLC's master-slave control mode combined with closed-loop feedback. In use, multiple units are sequentially placed next to the construction site wall panels, with the water pipe 4 positioned above the wall. When the wind direction above the device is from outside to inside the construction site, the water pipe 4 is flush against the wall, and the motor 3 controls the water pipe 4 to rotate so that the nozzle 6 faces upwards, allowing water droplets to enter the construction site with the wind and fall onto the ground, reducing surface dust and dust generation. When the wind direction above the device is from inside to outside the construction site, the left and right electric lifting rods 1 and 2 are controlled synchronously. The system rises while simultaneously controlling the rotation of motor 3. Based on the height of the rising dust, the spray angle of nozzle 6 is adjusted so that dust carried by the wind over the wall can be captured by the sprayed droplets, achieving a good spraying effect. Additionally, when the wind blows at an angle, some spraying equipment is in a dust suppression blind zone. The position of gate 11 can be adjusted by controlling the extension and retraction of two waterproof electric telescopic rods 14, thereby adjusting the water flow of nozzle 6 and achieving rational water usage. This device allows for convenient adjustment of the spray direction and position according to different wind directions, and also allows for adjustment of the water flow of some equipment according to specific spraying needs, resulting in greater water conservation.
