[0034] The rotating ring assembly 6 can drive the plurality of swing nozzle assemblies 7 to rotate around the center of the rotating ring assembly 6, making the water spraying directions of the plurality of swing nozzle assemblies 7 more extensive and ensuring comprehensive spraying;

[0035] The reciprocating linkage mechanism 8 is used to drive a plurality of the swing nozzle assemblies 7 to swing at a reciprocating angle simultaneously when the rotary ring assembly 6 performs a rotary motion, so as to achieve multi-angle spraying and dust removal, make the water spraying angle wider, and ensure comprehensive spraying; the water delivery assembly 9 ensures that external water sources can also perform a water delivery action on the swing nozzle assemblies 7 during the swinging and rotating processes of the swing nozzle assemblies 7.

[0040] A display screen 100, a control switch 200, a central processing unit 300 and a voice and communication alarm device 400 are arranged on the mobile device 1 of the present invention, and the central processing unit 300 is communicatively connected to the control switch 200, the display screen 100 and the voice and communication alarm device 400;

[0041] The first step: Before the operation of a water pumping and dust reduction device and its usage method for subway construction, first check the power device. The central processing unit 300 will display the power supply situation on the display 100, and it can be powered by 220V voltage or driven by diesel.

[0042] The second step: Then check whether all the devices in a water pumping and dust reduction device for subway construction are operating normally. After the check is correct, start entering the working area.

[0043] The third step: When starting to work before the operation of the water pumping and dust reduction device, the central control device 300 controls the lifting device 2 to automatically lower and the sealing plate to open, fixes the water pumping and dust reduction device, and fixes the output end of the water pumping device 3 to the pipe sleeve of the water suction pipe.

[0044] Step 4: Manually place a section of the water extraction pipe with the pressure sensor 4 at the water seepage point. The pressure sensor 4 monitors the water pressure, and the data is transmitted to the central processor 300. When it reaches a certain starting pressure threshold, the reading is displayed on the display 100, and the central control device 300 controls the water extraction device 3 to start. The seepage water is injected into the drain pipe through power drive and finally reaches the designated drainage point through the drainage hose.

[0045] Step 5: During the operation of the water extraction and dust reduction equipment, the pressure sensor 4 monitors the change rate of the seepage water in real time, and the reading is displayed on the display 100. The transmission power is automatically adjusted according to the magnitude of the change rate, and reasonable allocation is made to reduce the workload of workers. In case of an emergency, the central control device 300 promptly brakes the water extraction device 3 and the water purification device, and signals are sent through the communication device, and the voice and communication alarm device 400 automatically turns on and alerts the construction personnel.

[0046] Step 6: After the operation ends, when the pressure of the pressure sensor 4 drops to a certain braking pressure threshold, the central control device 300 controls the water pump to brake, and the purified water is stored in the water storage tank 5.

[0047] Step 7: When a sudden dust event occurs during construction, the water stored in the water storage tank 5 can be promptly pumped through the high-pressure pump and then transported to the swing nozzle assembly 7 through the water delivery assembly 9 for spraying, so as to quickly suppress the air dust content.

[0048] Step 8: When a sudden small fire accident occurs during construction, the water volume of the nozzle can be adjusted to promptly handle the fire.

[0049] The phenomenon of not utilizing the underground seepage water. The purpose of the present invention is to produce a highly automated device that can utilize the water resources generated during subway construction, enabling the utilization of neglected resources.

The central controller and the pressure sensor can realize the automatic operation of the equipment and achieve unmanned operation. The alarm and communication device can respond in a timely manner when a large amount of water seeps, enabling the staff to handle the water seepage phenomenon immediately. And when there is dust in the tunnel, the equipment can be used on-site to reduce the dust in the air. It can also quickly control and handle the fire when a fire accident occurs;
