[0027] A water supply pipe 2 is provided on the support column 11 in the vertical direction, a shunt pipe 3 connected to the water supply pipe 2 is provided on the cross beam 12 in the horizontal direction, and a plurality of water outlets 4 are provided on the shunt pipe 3 toward the bottom of the cross beam 12, and each water outlet 4 is connected to a multifunctional spray assembly 5 capable of dust reduction and fire extinguishing;

[0028] A dust identification component 6 and a fire warning component 7 are provided on the frame 1, and an electric valve 21 is provided on the water supply pipe 2. The electric valve 21, the fire warning component 7, the dust identification component 6 and the multifunctional spray component 5 are all connected to the same central control platform for communication.

[0029] The present invention can realize the switching of the dual working modes of dust reduction and fire extinguishing by setting a multifunctional spray component 5 with dual working modes. By controlling the operation of nozzles with different functions of the spray component, the multifunctional spray component 5 can spray dust reduction or form a water curtain to block the fire, and effectively reduce the dust concentration in the working environment, thereby greatly improving the safety and emergency handling capabilities of the mine.

[0030] The support column 11 and the crossbeam 12 form a door frame shape, so that the crossbeam 12 can be erected above the conveyor belt in the lane, so that the multifunctional spray assembly 5 can face the conveyor belt from top to bottom. When dust or fire occurs on the conveyor belt, the multifunctional spray assembly 5 sprays water mist or water curtain from top to bottom, which is convenient for the water mist to fall and absorb the dust, and also convenient for the water curtain to spray from top to bottom to extinguish the fire. The setting of the electric valve 21 can uniformly manage the water output of each water outlet 4. By controlling the switch, opening amount and opening frequency of the electric valve 21, the water output, water output frequency and water output intensity of the multifunctional spray assembly 5 can be controlled.

[0031] In some embodiments, the multifunctional spray assembly 5 includes an electric three-way valve 51 connected to the shunt pipe 3, and the other two ends of each electric three-way valve 51 are both arranged toward the bottom of the crossbeam 12. One end of the electric three-way valve 51 is connected to a spray nozzle 52, and the other end of the electric three-way valve 51 is connected to a fan-shaped nozzle 53. The setting of the electric three-way valve 51 can realize the intelligent control switching of the two nozzles. When dust reduction operation is required, it is necessary to spray water in a mist form to achieve dust reduction. The electric three-way valve 51 is controlled by the central control platform to open the waterway leading to the spray nozzle 52, and the spray dust reduction operation is performed through the spray nozzle 52; when fire extinguishing operation is required, it is necessary to spray water to the conveyor belt below in a water curtain form to achieve the effect of fire extinguishing, and the electric three-way valve 51 is controlled by the central control platform to open the waterway leading to the fan-shaped nozzle 53, and close the waterway leading to the atomizing nozzle, and the fan-shaped nozzle 53 sprays the water curtain to perform the fire extinguishing operation.

[0032] In some embodiments, the support column 11 and the cross beam 12 can be detachably connected, and the support column 11 and the cross beam 12 are divided into multiple groups of module structures with the same specifications, each module structure can be detachably connected, and each module structure has the same structural form. By designing the support column 11 and the cross beam 12 separately, it is convenient to move in the underground tunnel, and further, the support column 11 and the cross beam 12 are divided into a module structure with a certain specification, and each module structure has the same material selection and structural form, and is detachably fixed and connected by long bolts. The dead weight of each single module structure can be controlled within the tolerable range of a single person, and the customized frame 1 of the etching realizes batch organization at the component or material level.

[0033] In some embodiments, the dust identification component 6 includes a dust sensor 61 disposed on the frame 1, and the dust sensor 61 is connected to the central control platform for communication. During the dust reduction operation, the dust concentration in the environment is detected by the dust sensor 61, and the central control platform can intelligently control the electric ball valve driver to adjust the opening frequency and intensity of the spray device according to the dust and smoke concentration in the environment, and then adjust the frequency and intensity of the sprayed water mist, so as to achieve targeted and precise water supply for dust reduction, reduce the waste of water resources caused by excessive spraying during the dust reduction process, and reduce the occurrence of poor dust reduction effects due to insufficient spraying.

[0034] In some embodiments, the fire warning component 7 includes a temperature sensor 71, a smoke sensor 72, and an infrared sensor 73 arranged on the rack 1, and the temperature sensor 71, the smoke sensor 72, and the infrared sensor 73 are all arranged to communicate with the central control platform. The temperature sensor 71 and the delay sensor will monitor the temperature and smoke concentration in the environment in real time. When the ambient temperature or the smoke concentration in the environment reaches or exceeds the safety threshold preset by the central control platform, the control center will issue a fire alarm. The staff will determine whether a fire has occurred on the scene according to the fire alarm. When it is determined that a fire has occurred, the electric three-way valve 51 is controlled to connect to the fan-shaped nozzle 53 to perform fire extinguishing operations.

[0035] In some embodiments, the electric valve 21 is configured as an electric ball valve. The configuration of the electric ball valve can make it more convenient for the staff to use the central control platform to control the water supply amount, water supply intensity and water supply frequency in the water supply pipe 2.

[0036] The present invention also provides a method for using a multifunctional spray device for a mine, as shown below: Figure 2 Elaborate in detail.

[0037] A method for using a multifunctional spray device in a mine, including a dust reduction mode and a fire extinguishing mode;

[0038] The method of using the dust reduction mode includes: the dust identification component 6 monitors the dust concentration in the air in real time and transmits the data to the central control platform in real time. After the central control platform detects that the dust concentration is higher than the threshold, the central control platform controls the electric valve 21 to open, the water supply pipe 2 supplies water to the multifunctional spray component 5, and the central control platform controls the electric three-way valve 51 to open the spray nozzle 52 in the multifunctional spray component 5 to perform atomization dust reduction;

[0039] The method of using the fire extinguishing mode includes that the fire warning component 7 monitors the temperature and smoke concentration in the environment in real time and transmits the data to the central control platform in real time. When the central control platform detects that the ambient temperature or smoke concentration exceeds the safety threshold, the central control platform controls the electric valve 21 to open, and controls the electric three-way valve 51 to switch the nozzle in the multi-functional spray component 5 to the fan-shaped nozzle 53 to perform fire extinguishing spray.

[0040] The multifunctional spray assembly 5 includes a fan-shaped nozzle 53 and a spray nozzle 52. The direction of the water channel is controlled by an electric three-way valve 51, so that the spray system can spray dust or form a water curtain to block the spread of fire. This can effectively reduce the dust concentration in the working environment and protect the health of workers, and greatly improve the safety and emergency handling capabilities of the mine.

[0041] The dust identification component 6 and the fire warning component 7 monitor the airflow conditions in the belt conveyor lane in real time. If the dust concentration increases, the spray process is increased to quickly spray and reduce dust. In case of a sudden fire, the central control platform 5 controls the electric three-way valve 51 to switch the water path, so that the fan-shaped nozzle 53 works, forming a water curtain in the lane to extinguish the fire on the current belt, prevent the fire from spreading, and improve underground safety.

[0042] In one embodiment, when the central control platform detects that the ambient temperature or smoke concentration reaches or exceeds a threshold value and issues a fire alarm, and the smoke concentration in the environment is still at a level that requires dust reduction operations, the electric three-way valve 51 is preferentially controlled to open the water path to the fan-shaped nozzle 53 to perform fire extinguishing operations.

[0043] In one embodiment, in the dust reduction mode, the central control platform monitors and analyzes the dust concentration in real time, and controls the electric valve 21 driver to adjust the frequency and intensity of water supply according to the changes in dust concentration, thereby controlling the atomization intensity and opening frequency of the atomizing nozzle to achieve precise dust reduction.

[0044] In one embodiment, when the central control platform detects that the ambient temperature and smoke concentration exceed the safety threshold, it sends out a fire signal to notify relevant personnel to confirm the on-site situation. When the personnel confirm that a fire has occurred, the central control platform controls the electric valve 21 to open, and controls the electric three-way valve 51 to switch the nozzle in the multi-functional spray assembly 5 to the fan-shaped nozzle 53 for fire extinguishing spray.
