By setting the first magnet and the second magnet, the rotating bar can be driven to rotate when the fan blades rotate, so that the water in the water storage chamber rotates to generate a vortex, so that the blades can rotate with the flow of water, and then the disc is driven to rotate through the hard pipe, so that the area of ​​the atomizing nozzle when spraying water can be expanded, thereby improving the dust reduction efficiency.

[0017] 3. By setting a card joint to connect the hose to the water pump inlet pipe through the connecting pipe, the hose will not rotate when the micro water pump rotates with the disc, and the presence of the steel ball can reduce friction. Since the gap between the card joint and the connecting pipe is very small, it will not affect the water pumping of the micro water pump.

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention.

[0028] Example 1

[0029] Reference Figure 1-6 An indoor dust reduction device for a construction site includes a shell 1, a partition 15 is fixedly connected to the bottom end between the inner walls on both sides of the shell 1 by bolts, the partition 15 divides the shell 1 into a water storage chamber at the top of the partition 15 and a dust suction chamber at the bottom of the partition 15, a negative pressure fan 10 is fixedly connected to the bottom end of the partition 15 by bolts, and a frame 14 is fixedly connected to the inner walls on both sides of the dust suction chamber by bolts. The frame 14 is below the negative pressure fan 10, and an opening is opened in the middle of the frame 14. The frame 14 is fixedly connected with an isolation pad 11 at the opening by bolts. The material of the isolation pad 11 is porous material. A dust suction port 12 is opened at the bottom end of the shell 1 below the isolation pad 11, so that negative pressure can be generated by the negative pressure fan 10, so that dust on the ground can be sucked into the dust suction chamber from the dust suction port 12. At the same time, the isolation pad 11 needs to be wetted with water before using the device, so when dust enters the dust suction chamber, the dust will be blocked by the isolation pad 11, so that the working state of the negative pressure fan 10 will not be affected by the dust.

[0030] The negative pressure fan 10 includes a casing 101, a fan blade 102, a motor 103, a connecting frame 104 and a power module. The casing 101 is fixedly connected to the partition by bolts, and a circular opening is opened in the middle of the casing 101. There are four connecting frames 104, and the four connecting frames 104 are equidistantly fixedly connected to the inner side of the circular opening by bolts. The motor 103 is fixedly connected to the four connecting frames 104 by bolts, and the motor 103 is electrically connected to the power module. The fan blade 102 is fixedly connected to the output shaft of the motor 103 by bolts. The top of the fan blade 102 is fixedly connected to two first magnets 16 by bolts, and the two first magnets 16 are centrally symmetrical. The middle part of the top of the partition 15 is rotatably connected to a rotating bar 9 through a rotating shaft. Circular through holes are opened at both ends of the rotating bar 9, and the rotating bar 9 is fixedly connected to the second magnet 17 at the two circular through holes by bolts, and the magnetic pole at the bottom end of the second magnet 17 is different from the magnetic pole at the top end of the first magnet 16.

[0031] A water inlet is provided at the top of the shell 1, and the shell 1 is fixedly connected to the same support frame 4 at both sides of the water inlet by bolts, the support frame 4 includes a first support frame 401 and a second support frame 402, the first support frame 401 and the second support frame 402 are respectively located on both sides of the water inlet, and a bearing 21 is fixedly connected between the first support frame 401 and the second support frame 402 by bolts, the inner side of the inner ring of the bearing 21 is fixedly connected to a hard tube 25 by bolts, the hard tube 25 extends to the inside of the shell 1 at the water inlet, and both sides of the bottom end of the hard tube 25 are fixedly connected to connecting rods 3 by bolts, the two connecting rods 3 are both L-shaped, and the ends of the two connecting rods 3 away from the hard tube 25 are fixedly connected to the blades 2 by bolts, the two blades 2 are both inside the shell 1, and the top of the hard tube 25 is fixedly connected to The disc 5 has three atomizing nozzles 6 fixedly connected to the top of the disc 5 at equal intervals by bolts, and the inside of the disc 5 is fixedly connected to a micro water pump 18 by bolts, the water inlet of the micro water pump 18 is fixedly connected to a water pump water inlet pipe 22 by bolts, and the water outlet of the micro water pump 18 is fixedly connected to a water outlet pipe 20 by bolts, and the other end of the water outlet pipe 20 is fixedly connected to a four-way pipe by bolts, and the three water outlets of the four-way pipe are fixedly connected to the three atomizing nozzles 6 by bolts. A second hose 19 is fixedly connected to the three atomizing nozzles 6 by bolts, so that the rotating bar 9 can be driven to rotate when the fan blades 102 rotate, so that the water in the water storage chamber rotates to generate a vortex, so that the blades 102 can rotate with the flow of water, and then the disc 5 is driven to rotate through the hard tube 25, so that the area of ​​the atomizing nozzle 6 when spraying water can be expanded, thereby improving the dust reduction efficiency.

[0032] The bottom end of the water pump inlet pipe 22 is inside the hard pipe 25, and the bottom end of the water pump inlet pipe 22 is fixedly connected to the clamp joint 23 by bolts, a first groove is provided at the bottom end of the side wall of the clamp joint 23, and a connecting pipe 28 is sleeved on the outside of the clamp joint 23, a second groove is provided at the top end of the inner wall of the connecting pipe 28, and a steel ball 24 is provided between the first groove and the second groove, the bottom end of the connecting pipe 28 extends to the bottom end of the hard pipe 25, and the bottom end of the connecting pipe 28 is fixedly connected to the first hose 7 by bolts, and the other end of the first hose 7 extends to the partition The top of the partition 15 is fixedly connected with a fixing frame 8 by bolts at one side of the rotating bar 9. The fixing frame 8 is fixedly connected with the first hose 7 by bolts, so that the first hose 7 will not rotate when the micro water pump 18 rotates with the disc 5, and the presence of the steel ball 24 can reduce the friction force. Since the gap between the clamping joint 23 and the connecting pipe 28 is very small, it will not affect the water pumping of the micro water pump 18. Even if water can flow out from the gap between the clamping joint 23 and the connecting pipe 28, the water will flow into the water storage chamber and will not be wasted.

[0033] During use: first inject clean water into the water storage chamber, then wet the isolation pad 11 with water, and then start the negative pressure fan 10. At this time, the negative pressure fan 10 rotates to generate negative pressure, so that the dust on the ground can be sucked into the dust suction chamber from the dust suction port 12. After the dust enters the dust suction chamber, the dust will contact the isolation pad 11, so that the dust is adsorbed by the isolation pad 11, and will not reach the negative pressure fan 10 and contact it.

[0034] When the negative pressure fan 10 rotates, the fan blade 102 drives the first magnet 16 to rotate, and the first magnet 16 drives the rotating bar 9 to rotate through the second magnet 17, so that the water in the water storage chamber rotates to generate a vortex. At this time, the blade 2 can rotate with the flow of water, thereby driving the hard tube 25 to rotate. When the hard tube 25 rotates, it drives the disc 5 to rotate, and the disc 5 can drive the atomizing nozzle 6 to rotate. At this time, the micro water pump 18 is started, and the micro water pump 18 can pump the water in the water storage chamber to the atomizing nozzle 6, so that the device can perform dust reduction treatment in the room. In this process, since the micro water pump 18 rotates with the disc 5, the water pump inlet pipe 22 will also rotate, but since a steel ball 24 is provided between the water pump inlet pipe 22 and the connecting pipe 28, the rotation of the water inlet pipe 22 will not affect the connecting pipe 28 and the first hose 7.

[0035] Example 2

[0036] Reference Figure 7, an indoor dust reduction device for construction sites. Compared with Example 1, in order to make the replacement and cleaning of the isolation pad 11 more convenient, the frame 14 of this embodiment includes a first frame 1401 and a second frame 1402. The first frame 141 and the second frame 142 are fixedly connected with a hinge 26 by bolts, and the four corners of the top of the second frame 142 are fixedly connected with fixing piles 27 by bolts. Fixing holes are opened at the four corners of the isolation pad 11, and the fixing piles 27 are adapted to the fixing holes. Therefore, the isolation pad 11 can be easily removed after use by separating the first frame 141 and the second frame 142, thereby facilitating the replacement and cleaning of the isolation pad 11.

[0037] During use: first inject clean water into the water storage chamber, then take out the frame 14 and separate the first frame 141 and the second frame 142. At this time, the isolation pad 11 can be taken out from the fixed pile 27, and then the isolation pad 11 is wetted with water, and the isolation pad 11 is fixed to the frame 14 again, and the frame 14 is put back to its original position, and then the negative pressure fan 10 can be started. At this time, the negative pressure fan 10 rotates to generate negative pressure, so that the dust on the ground can be sucked into the dust suction chamber from the dust suction port 12. After the dust enters the dust suction chamber, the dust will contact the isolation pad 11, so that the dust is adsorbed by the isolation pad 11, so that it will not reach the negative pressure fan 10 and contact it.

[0038] When the negative pressure fan 10 rotates, the fan blade 102 drives the first magnet 16 to rotate, and the first magnet 16 drives the rotating bar 9 to rotate through the second magnet 17, so that the water in the water storage chamber rotates to generate a vortex. At this time, the blade 2 can rotate with the flow of water, thereby driving the hard tube 25 to rotate. When the hard tube 25 rotates, it drives the disc 5 to rotate, and the disc 5 can drive the atomizing nozzle 6 to rotate. At this time, the micro water pump 18 is started, and the micro water pump 18 can pump the water in the water storage chamber to the atomizing nozzle 6, so that the device can perform dust reduction treatment in the room. In this process, since the micro water pump 18 rotates with the disc 5, the water pump inlet pipe 22 will also rotate, but since a steel ball 24 is provided between the water pump inlet pipe 22 and the connecting pipe 28, the rotation of the water inlet pipe 22 will not affect the connecting pipe 28 and the first hose 7.

[0039] After the dust reduction is completed, the frame 14 is taken out again, and the isolation pad 11 is taken out by wetting the isolation pad 11, and the isolation pad 11 can be replaced and cleaned.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
