Description

Technical Field

[0001] The utility model relates to a dust reduction device, which is applicable to the technical field of dust reduction devices for building construction. Background Art

[0002] A dust reduction device is a device used to remove suspended particulate matter in the air. It is usually used in construction sites, municipal engineering and other places, and can effectively reduce the impact of dust on the surrounding environment and the health of residents. Currently, the common dust reduction method in construction sites and municipal engineering is to install nozzles on the construction enclosure and supply water to the nozzles to prevent the dust inside the construction site and municipal engineering from flying outwards. However, the dust flying situation inside the construction enclosure is still relatively serious, which is likely to affect the physical health of construction workers. At the same time, since the nozzles are fixedly installed on the construction enclosure, it is not convenient to adjust the spraying direction of the nozzles, and the dust reduction efficiency is poor. Content of the Utility Model

A positioning block is installed on the chuck at a position corresponding to the nozzle. A positioning groove is made on the nozzle at a position corresponding to the positioning block. A telescopic adjustment mechanism is provided between the fixed disk and the chuck. In this way, when the chuck moves towards the fixed disk, the positioning block on the chuck is inserted into the positioning groove on the nozzle, and the nozzle is locked under the cooperation of the nozzle and the positioning block; when the chuck moves away from the fixed disk, the positioning block on the chuck and the positioning groove on the nozzle are disengaged, so as to facilitate the removal of the nozzle from the fixed disk.

Detailed Description of the Preferred Embodiment

[0021] The present utility model will be further described in detail below with reference to the drawings and through embodiments. The following embodiments are explanations of the present utility model, and the present utility model is not limited to the following embodiments.

[0022] This embodiment is a dust reduction device, which has a base 2. A water tank 1 is installed on the base 2. A booster pump 20 is provided on the water tank 1. The booster pump 20 can pump air into the water tank 1 to press out the water stored in the water tank 1. A pressure gauge 19 and a pressure relief valve 18 are provided on the water tank 1. In this way, it is convenient for personnel to determine the pressure condition in the water tank 1 by checking the pressure gauge 19, and release the pressure in the water tank 1 through the pressure relief valve 18 when the pressure in the water tank 1 is high, so as to prevent the water tank 1 from being damaged due to excessive internal pressure.

[0023] An inlet 21 is opened on the water tank 1, and a cover is arranged at the inlet 21. In this way, it is convenient to supplement the water stored in the water tank 1 through the inlet 21 after the water stored in the water tank 1 is used up.

[0024] In this embodiment, a rotatable turntable 3 is installed on the top of the water tank 1. A driving motor 4 is arranged in the base 2 at the bottom of the water tank 1. A connecting shaft is installed on the output shaft of the driving motor 4, and the end of the connecting shaft is connected to the turntable 3. In this way, the turntable 3 can be driven to rotate when the driving motor 4 operates.

[0025] In this embodiment, a cavity is arranged in the turntable 3. A sleeve 5 is sleeved on the connecting shaft. The end of the sleeve 5 is connected to the turntable 3. A water inlet groove 5-1 is formed on the sleeve 5. The sleeve 5 is communicated with the cavity. In this way, after the booster pump 20 pumps air into the water tank 1, the water stored in the water tank 1 will flow into the sleeve 5 through the water inlet groove 5-1 and finally flow into the cavity of the turntable 3.

[0026] In this embodiment, a bracket is installed on the turntable 3. The bracket has a fixed rod 11 fixedly installed on the turntable 3. A fixed disk 10 is installed at the end of the fixed rod 11. A connecting rod 9 is connected between the fixed disk 10 and the fixed rod 11. At least two nozzles 7 are arranged on the fixed disk 10 along the circumferential direction of the fixed disk 10. In this embodiment, three nozzles 7 are installed on the fixed disk 10. Three water supply pipes 6 are connected to the three nozzles 7, and the end of the water supply pipe 6 is communicated with the cavity of the turntable 3. In this way, when the driving motor 4 operates, it can drive the turntable 3, the bracket and the nozzles 7 to rotate. When the booster pump 20 operates, it can send the water stored in the water tank 1 into the cavity of the turntable 3, transport it to the nozzles 7 through the water supply pipe 6, and spray out from the nozzles 7. In this way, the nozzles 7 can spray water evenly around this dust reduction device and play a good dust reduction role. And because the water supply pipe 6 is communicated with the water tank 1 through the turntable 3, when the driving motor 4 drives the turntable 3 to rotate, the water supply pipe 6 can rotate with the turntable 3, avoiding the situation of the water supply pipe 6 getting knotted.

[0027] In this embodiment, a locking mechanism for locking the nozzle 7 is provided on the fixed disk 10. Specifically, a limiting block 8 is fixedly installed on the fixed disk 10. The shape of the limiting block 8 is matched with that of the nozzle 7. A chuck 12 is installed on the fixed disk 10. A handle 15 is installed on the chuck 12. A positioning block 17 is installed on the chuck 12 at a position corresponding to the nozzle 7. A positioning groove 16 is formed on the nozzle 7 at a position corresponding to the positioning block 17. A telescopic rod 13 is installed between the chuck 12 and the fixed disk 10. A spring 14 is sleeved on the telescopic rod 13. Two ends of the spring 14 are respectively fixedly connected to the chuck 12 and the fixed disk 10. Thus, under the action of the spring 14, the telescopic rod 13 remains in a retracted state, enabling the positioning block 17 on the chuck 12 to cooperate with the positioning groove 16 on the nozzle 7, and positioning and installing the nozzle 7 on the fixed disk 10. When it is necessary to replace the nozzle 7, by operating the handle 15 to drive the chuck 12 to move away from the fixed disk 10 until the positioning block 17 on the chuck 12 and the positioning groove 16 on the nozzle 7 are not in a cooperating position, it is convenient to remove the nozzle 7 from the fixed disk 10 and replace it.
