The cross beam extends in the left and right directions and is connected between the top ends of the left beam and the right beam.

The pressurizing device makes the medium pressure in the first water pipe higher than the medium pressure in the second water pipe, so that the water spraying effects of the first nozzle and the second nozzle are different, which can be used for different operational requirements.

[0031] Preferably, the second nozzle 3 is turned on and the first nozzle 2 is turned off when performing dust reduction operations, and the first nozzle 2 is turned on and the second nozzle 3 is turned off when performing firefighting operations, or the first nozzle 2 and the second nozzle 3 are turned on at the same time.

[0032] Preferably, the tunnel dust reduction fire fighting equipment of the embodiment of the utility model is used in a belt conveyor tunnel, the conveyor belt passes through the frame 1, and the second nozzle 3 is set toward the conveyor belt to reduce the dust generated when the conveyor belt transports minerals, especially coal ore.

[0033] In some embodiments, the first nozzle 2 is a fan-shaped nozzle, and the medium sprayed by the first nozzle 2 is in the shape of a water curtain, so that the state of the medium sprayed by the first nozzle 2 is more suitable for firefighting operations. The second nozzle 3 is a conical nozzle, and the medium sprayed by the second nozzle 3 is in the shape of a dispersed mist, so that the state of the medium sprayed by the second nozzle 3 is more suitable for dust reduction operations.

[0034] In some embodiments, there are multiple first nozzles 2, which are spaced apart and arranged on the top of the rack 1 and connected in series with the first water pipe 4. There are multiple second nozzles 3, which are spaced apart and arranged on the top of the rack 1 and connected in series with the second water pipe 5.

[0035] like Figure 1 As shown, multiple first nozzles 2 are provided on the crossbeam and spaced apart in the left-right direction so that the medium sprayed by the multiple first nozzles 2 can cover the space surrounding the frame 1 in the left-right direction, thereby ensuring the fire extinguishing effect. Preferably, when the first nozzle 2 is a fan-shaped nozzle, the end of the fan-shaped nozzle is provided with a nozzle slot connected to its nozzle, and the nozzle slot is a strip extending in the radial direction of the first nozzle 2. The nozzle slot of each fan-shaped nozzle is arranged in the left-right direction.

[0036] The plurality of second nozzles 3 are provided on the crossbeam and are spaced apart in the left-right direction so that the medium sprayed by the plurality of second nozzles 3 can fill the space around the frame 1 in the left-right direction, thereby ensuring the dust reduction effect.

[0037] In some embodiments, the pressurizing device 6 is a piston-type pressurizing pump.

[0038] like Figure 1 and Figure 2 As shown, the pressurizing device 6 is preferably a piston-type pressurizing pump, which is arranged on the frame 1, and more preferably on the crossbeam.

[0039] It can be understood that the pressurizing device is not limited to being a piston-type pressurizing pump. In other embodiments, the pressurizing device is a centrifugal pressurizing pump.

[0040] In some embodiments, the piston-type pressure pump is arranged outside the first water pipe 4 and is connected to the first water pipe 4. The piston-type pressure pump extends along the direction of medium flow in the first water pipe 4 and is inclined toward the first water pipe 4 along the radial direction of the first water pipe 4.

[0041] like Figure 1 and Figure 2 As shown, the piston-type pressure pump is arranged outside the pipe wall of the first water pipe 4 and is connected to the first water pipe 4. The medium in the part of the first water pipe 4 located at the crossbeam flows from left to right, and the piston-type pressure pump extends from left to right and is inclined in the up and down directions toward the first water pipe 4. Preferably, the piston-type pressure pump is arranged at the upper end of the first water pipe 4, the piston-type pressure pump extends from left to right, and is inclined from top to bottom, so that the pressure direction applied by the piston-type pressure pump to the medium in the first water pipe 4 is downstream of the flow direction of the medium in the first water pipe 4.

[0042] In some embodiments, the piston-type pressure pump includes a pressure cylinder 61, a piston 62, and a driving member 63. The piston 62 is arranged in the pressure cylinder 61 and divides the inner cavity of the pressure cylinder 61 into a first cavity and a second cavity arranged along the axial direction of the pressure cylinder 61. The cylinder wall of the pressure cylinder 61 is provided with a vent hole 66 connected to the first cavity, and the second cavity is connected to the first water pipe 4. The driving member 63 is connected to the piston 62 or the first cavity to drive the piston 62 to move along the axial direction of the pressure cylinder 61.

[0043] like Figure 1 and Figure 2 As shown, the pressurizing cylinder 61 is a cylinder with a closed left end and an open right end. Figure 2 The pressure cylinder 61 shown is only partially shown. The pressure cylinder 61 is arranged at the upper end of the first water pipe 4. The pressure cylinder 61 extends from left to right and is tilted from top to bottom. The right end of the pressure cylinder 61 is connected to the first water pipe 4.

[0044] The piston 62 is arranged in the pressure cylinder 61, and the outer circumferential surface of the piston 62 is against the inner circumferential surface of the pressure cylinder 61 to divide the inner cavity of the pressure cylinder 61 into a first cavity and a second cavity arranged in sequence along the left and right directions. The first cavity is located on the left side of the second cavity, and the second cavity is connected to the first water pipe 4. The left end wall of the pressure cylinder 61 is provided with an air vent 66 connected to the first cavity.

[0045] The driving member 63 is connected to the piston 62 to drive the piston 62 to move in the left-right direction, or the driving member 63 is connected to the first chamber to drive the piston 62 to move in the left-right direction by supplying and withdrawing the medium into the first chamber.

[0046] The volumes of the first and second chambers change as the piston 62 moves. The vent 66 connects the first chamber to the external environment of the piston-type pressure pump to prevent pressure from building up in the first chamber when the piston 62 moves. The second chamber expands as the piston 62 moves leftward, thereby drawing some of the medium in the first water pipe 4 into the second chamber. Since the first water pipe 4 has a continuous supply of medium, the pressure does not drop due to the withdrawal of the medium. The second chamber decreases as the piston 62 moves rightward, thereby pushing the medium in the second chamber back into the first water pipe 4. Since the first water pipe 4 has a continuous supply of medium, the pressure increases after receiving the medium provided by the second chamber.

[0047] Preferably, the piston-type pressure pump also includes a sealing ring 65, which surrounds the outer circumference of the piston 62 and abuts against the inner circumference of the pressure cylinder 61 to seal the connection between the piston 62 and the pressure cylinder 61, preventing the medium in the first chamber from entering the second chamber, and preventing the medium in the second chamber from entering the first chamber, especially preventing the medium in the second chamber from entering the first chamber, thereby causing leakage of the medium in the first water pipe 4 and pressure relief.

[0048] In some embodiments, the piston-type pressure pump also includes a crank-connecting rod mechanism 64, which is penetrated through the wall of the pressure cylinder 61 and one end is located in the first cavity. The crank-connecting rod mechanism 64 is located in the first cavity at one end connected to the piston 62, and the other end located outside the pressure cylinder 61 is connected to the driving member 63.

[0049] like Figure 2 As shown, a crank-connecting rod mechanism 64 passes from the outside environment through the wall of the pressurizing cylinder 61 into the first chamber. One end of the crank-connecting rod mechanism 64 located in the first chamber is connected to the piston 62, and the other end of the crank-connecting rod mechanism 64 located in the outside environment is connected to the driving member 63, thereby driving the piston 62 to move in the left and right directions under the drive of the driving member 63. The driving member 63 is preferably a rotary motor and is installed on the crossbeam.

[0050] In some embodiments, the tunnel dust suppression fire-fighting equipment of the embodiment of the utility model also includes a main water pipe 7, a main valve 8 and a multi-way valve 9. The main water pipe 7 is connected to the first water pipe 4 and the second water pipe 5 through the multi-way valve 9. The multi-way valve 9 can adjust the flow and opening and closing of the first water pipe 4 and the second water pipe 5 respectively. The main valve 8 is arranged on the main water pipe 7 to adjust the flow and opening and closing of the main water pipe 7.

[0051] like Figure 1 As shown, one end of the main water pipe 7 extends from the outside of the frame 1 to the left beam, and the left beam is provided with a multi-way valve 9, which is preferably an electric three-way valve. The inlet end of the electric three-way valve is connected to the main water pipe 7, and one outlet end of the electric three-way valve is connected to the first water pipe 4, and the other outlet end is connected to the second water pipe 5, so that the first water pipe 4 and the second water pipe 5 are connected in parallel to the main water pipe 7, which is convenient for supplying medium to the first nozzle 2 and the second nozzle 3. At the same time, the flow and opening and closing of the first water pipe 4 and the second water pipe 5 can be respectively adjusted by the electric three-way valve, which is preferably an electric three-way valve.

[0052] The left beam is also provided with a main valve 8, which is arranged on the main water pipe 7 to adjust the flow and opening and closing of the main water pipe 7.

[0053] Preferably, when dust reduction operations and fire fighting operations are not required, the main valve 8 is closed; when dust reduction operations are performed, the main valve 8 is opened, the electric three-way valve connects the main water pipe 7 and the second water pipe 5, and isolates the main water pipe 7 and the first water pipe 4; when fire fighting operations are performed, the main valve 8 is opened, the electric three-way valve connects the main water pipe 7 and the first water pipe 4, and isolates the main water pipe 7 and the second water pipe 5, or the electric three-way valve connects both the first water pipe 4 and the second water pipe 5 to the main water pipe 7.

[0054] Preferably, the medium in the first water pipe 4 and the second water pipe 5 is water from the main water pipe 7. It can be understood that the medium in the first water pipe 4 is not limited to water. In other embodiments, the first water pipe is also connected to the supply pipe. The connection position of the supply pipe on the first water pipe is located between the electric three-way valve and the first nozzle. The supply pipe is used to supply high-concentration fire-fighting medium to the first water pipe. The fire-fighting medium is mixed with the water from the main water pipe in the first water pipe and then sprayed out by the first nozzle.

[0055] It is understandable that, in other embodiments, the first water pipe and the second water pipe may also be provided separately and connected to the medium supply equipment respectively.

[0056] In some embodiments, the tunnel dust reduction and fire fighting equipment of the embodiment of the utility model also includes a dust sensor and a control terminal. The dust sensor can be arranged on the frame 1, or on the inner wall of the tunnel and arranged at intervals with the frame 1, or on the belt conveyor equipment passing through the frame 1 and arranged at intervals with the frame 1. The dust sensor is used to detect the dust concentration.

[0057] The dust sensor is electrically connected to the control terminal to transmit the detected dust concentration data to the control terminal.

[0058] The control terminal is electrically connected to the main valve 8 and the multi-way valve 9 to adjust the opening and closing and opening degree of the main valve 8 and the multi-way valve 9 according to the received dust data. Preferably, the control terminal is provided with a preset dust concentration. When the detected dust concentration is greater than or equal to the preset dust concentration, dust reduction operation is required. The control terminal controls the main valve 8 to open, and controls the multi-way valve 9 to connect the main water pipe 7 and the second water pipe 5, and to isolate the main water pipe 7 from the first water pipe 4. The second nozzle 3 sprays the medium to reduce dust.

[0059] Furthermore, the control terminal can also adjust the opening of the main valve 8 and / or the multi-way valve 9 according to the detected dust concentration to adjust the flow rate of the second nozzle 3.

[0060] Furthermore, the control terminal can also adjust the opening and closing frequency of the main valve 8 and / or the multi-way valve 9 according to the detected dust concentration to adjust the operating frequency of the second nozzle 3.

The fire detection sensor is preferably at least one of a temperature sensor, a smoke sensor and an infrared sensor.

[0062] The fire detection sensor is electrically connected to the control terminal to transmit the detected corresponding temperature data and smoke concentration data to the control terminal.

[0063] The control terminal is electrically connected to the main valve 8 and the multi-way valve 9 to adjust the opening and closing and opening degree of the main valve 8 and the multi-way valve 9 according to the received data. Preferably, the control terminal is provided with preset temperature data and preset smoke concentration data. When the detected temperature data or smoke concentration data is greater than or equal to the preset value, fire extinguishing operations are required. The control terminal controls the main valve 8 to open and controls the electric three-way valve to connect the main water pipe 7 and the first water pipe 4 and isolate the main water pipe 7 and the second water pipe 5. Alternatively, the electric three-way valve is controlled to connect both the first water pipe 4 and the second water pipe 5 to the main water pipe 7.

[0064] More preferably, when the detected temperature data is greater than or equal to the preset temperature data, the control terminal controls the main valve 8 to open, and controls the electric three-way valve to connect the main water pipe 7 and the first water pipe 4. At the same time, when the detected smoke concentration data is greater than or equal to the preset smoke concentration data, the control terminal controls the electric three-way valve to connect the second water pipe 5 with the main water pipe 7. When the detected smoke concentration data is less than the preset smoke concentration data, the control terminal controls the electric three-way valve to isolate the main water pipe 7 and the second water pipe 5.

[0065] Furthermore, the control terminal can also adjust the opening of the main valve 8 and / or the multi-way valve 9 according to the detected temperature data and smoke concentration data to adjust the flow rate of the first nozzle 2 and the second nozzle 3.

[0066] Furthermore, the control terminal can also adjust the opening and closing frequency of the main valve 8 and / or the multi-way valve 9 according to the detected temperature data and smoke concentration data to adjust the operating frequency of the first nozzle 2 and the second nozzle 3.
