[0063] like Figure 2 , 3 , 4 shows a device for adjusting the spray range and angle of a fog cannon.

[0064] The fog cannon barrel 19 is arranged on the turntable 16; one end of the top of the turntable 16 is fixedly connected to the support column 18, and the top of the support column 18 is rotatably connected to the fog cannon barrel 19.

[0065] The electric telescopic rod 17 is turned on, and the electric telescopic rod 17 moves with one end of the fog cannon barrel 19 to adjust the height and angle of the output end of the fog cannon barrel 19.

[0070] By adjusting the spray angle and position of the fog cannon, dust reduction operations can be achieved over a larger area without moving the entire device, thus avoiding continuous dust generation.

[0071] like Figure 1 , 2 , 5 shows the structure of the device for adjusting the initial injection height.

[0072] A first motor 10 is fixedly connected to the top of the box body 2, and an output end of the first motor 10 is fixedly connected to one end of a bidirectional screw rod 9. When the first motor 10 is turned on, the first motor 10 drives the bidirectional screw rod 9 to rotate.

[0073] Two first moving blocks 11 are arranged on the bidirectional screw rod 9. The bidirectional screw rod 9 rotates and moves the first moving blocks 1111 at both ends.

[0074] The top of the first moving block 11 is rotatably connected with an adjusting rod 12. The adjusting rod 12 is provided with two groups. The two groups of adjusting rods 12 intersect in a cross shape, and the intersection point is rotatably connected through a rotating shaft.

[0075] One end of the adjusting rod 12 away from the first moving block 11 is rotatably connected to the second moving block 14 , and the interior of the second moving block 14 is slidably connected to the first sliding rod 13 ; both ends of the first sliding rod 13 are connected to fixing plates.

[0076] The first moving block 11 moves with the adjusting rod 12 , and the adjusting rod 12 moves with the second moving block 14 along the first sliding rod 13 , so that the fixing plate can move up and down.

[0077] The installation box 15 is installed on the fixed plate, and the installation box 15 can be driven to move up and down by the height adjustment device, so that the initial spray height of the fog cannon is adjusted.

[0078] When used manually, firstly, water is connected to the water from the water inlet 22, and the water pump 21 is turned on. The water pump 21 delivers the water in the water tank 23 into the fog cannon barrel 19 through the hose 20.

[0079] The installation box 15 moves with the turntable 16 and the fog cannon barrel 19 to adjust the height of the fog cannon barrel 19. When the output end of the fog cannon barrel 19 needs to be adjusted, the electric telescopic rod 17 can be started to adjust the height of the output end of the fog cannon barrel 19. The electric telescopic rod 17 moves one end of the fog cannon barrel 19 to adjust the angle of the fog cannon barrel 19. The second motor 24 is started, and the second motor 24 rotates with the reciprocating screw rod 25. The reciprocating screw rod 25 rotates and moves with the rack 28 on the outside of the second sliding rod 29. The rack 28 moves back and forth through the gear 27 and the rotating shaft 26 rotates back and forth. The rotating shaft 26 rotates and rotates the turntable 16. The turntable 16 rotates back and forth with the fog cannon barrel 19 through the support column 18, so that the spraying angle is reciprocated and the external dust is comprehensively reduced.

[0080] The water sprinkling method can be used alone to reduce dust, or the vacuuming operation can be used simultaneously.

[0081] The fan 6 is turned on, and dust enters the dust collecting box 3 from the dust suction port 7 and the connecting port 8. After being filtered by the filter plate 4, clean gas is discharged from the fan 6 through the connecting pipe 5.

[0082] If the water mist sprayed by the fog cannon is quickly sucked by the dust suction device, the first motor 10 can be started, and the first motor 10 rotates with the bidirectional wire, and the bidirectional wire rod 9 rotates to move the first moving blocks 11 at both ends, and the first moving block 11 moves on the outside of the first slide bar 13 with the second moving block 14 through the adjusting rod 12. With the movement of the two groups of second moving blocks 14 and the first moving block 11, the installation box 15 moves up and down, and the starting height of the water spray of the fog cannon is adjusted, so that the higher dust can be well controlled, and at the same time, the problem of the dust being sucked by the dust suction device before interacting with the dust in the air can be reduced.

[0083] In order to achieve automatic dust reduction operations according to the dust concentration during construction, while reducing ineffective energy consumption and the need to protect equipment.

[0084] The water sprinkling and dust suppression device is also provided with a detection device and a control device 33;

[0085] The detection device includes a wind speed detector 34 and a dust detection device 35.

[0086] The wind speed detector 34 and the dust detection device 35 are arranged on the dust collection device.

[0087] The control device 33 is arranged on the carrying device, and is connected to the watering device, the dust collecting device, and the detection device respectively by wired or wireless means, and controls the operation status of the watering device and the dust collecting device by analyzing the detection data of the detection device;

[0088] The dust detection device 35 is arranged on the dust suction port 7 and installed outside the dust suction port 7 to detect the dust situation around the equipment.

[0089] The wind speed detector 34 is installed on the connecting pipe 5 and is used to measure the wind volume and wind speed passing through the connecting pipe 5.

[0090] The control device 33 controls the connected watering device and dust collecting device through the data of each detector transmitted by the detection device.

[0091] When the automatic control mode is started, the water sprinkling and dust reduction device is powered on, and the control device 33 controls the connected device through a preset program.

[0092] Each detection device transmits the detected data to the control device 33. The control device 33 starts the sprinkler device and the dust collector according to the preset dust start threshold, and controls the sprinkler device by calling the preset watering amount and atomization degree according to the amount of dust. The dust collector can also be started at the same time, and the operating parameters of the fan 6 are called to perform dust collection operations.

[0093] For example, when the amount of dust is large, the amount of water sprayed is increased, the degree of atomization is increased, the operating power of the fan 6 of the dust collection device is increased, and the air volume is increased.

[0094] However, when it is found that the operating power of the fan 6 is within the high threshold range, the wind speed and air volume detected by the wind speed detector 34 are insufficient, and it can be judged that the filter plate 4 may reach the level of clogging, the dust removal effect will be reduced, and the power will be lost. At this time, an alarm is prompted and the operator cleans the filter plate 4. At the same time, the operation of the fan 6 is reduced or stopped to prevent the fan 6 from burning.

[0095] In practice, it is found that the use of water sprinkling will cause poor self-shedding effect of the dust on the filter plate 4. Therefore, an oscillator is connected to the filter plate 4 to regularly shake off the filtered dust, or when the air volume and wind speed tested by the wind speed detector 34 are insufficient, the oscillator is started to shake off the dust on the filter plate 4. This can reduce or avoid frequent alarms for a certain period of time, reducing the operating power of the fan 6 and causing a decrease in the dust removal effect.

[0096] The above-mentioned oscillator is connected to the control device 33 and can be controlled to start and stop. When the control device 33 determines that the air volume and wind speed measured by the wind speed detector 34 are at the low threshold, the oscillator is started to oscillate and shake off the dust on the filter plate 4. If the air volume and wind speed cannot be recovered for a long time after the oscillator is started, the fan operating power will be reduced or the fan will be stopped and an alarm will be issued, requiring manual cleaning.
