Description

Technical Field

[0001] The utility model relates to the technical field of ventilation devices, in particular to a safety ventilation device for underground operations. Background Art

[0002] Mine ventilation is an important part of mine safety production. Whether the mine ventilation method can work normally is closely related to the working environment conditions, production efficiency and safety production in the mine.

[0003] Generally speaking, the deeper the mine, the higher the underground temperature, because the temperature of the underground layer will be affected by geothermal heat. In addition, mining activities and the operation of mechanical equipment in the mine will also generate heat, further increasing the temperature of the underground working area. In some cases, the temperature of the underground working area may exceed the human comfort range and even reach a dangerous level. The high temperature environment will have an adverse effect on the physical health and work efficiency of the staff, and may cause heat stroke, excessive physical exhaustion, fatigue and other problems.

[0004] Most of the existing underground ventilation devices are not convenient for adjusting the ventilation angle, and the cooling effect on high-temperature areas is poor, and improvement is urgently needed. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the existing underground ventilation device is not convenient for adjusting the ventilation angle and has a poor cooling effect on high-temperature areas.

[0006] In order to solve the above problems, the technical solution of the utility model is: a safety ventilation device for underground operations, including a box body, a spray gun is installed on the top of the box body, and casters are installed on the bottom. Two support plates are fixedly connected to the top of the box body, and the spray gun is rotatably installed on the two support plates. A telescopic rod is hinged between the spray gun and the top surface of the box body. A partition is provided inside the box body, and the partition divides the inside of the box into a water storage bin and an equipment bin;

[0007] A semiconductor refrigerator, an atomizer and a cooling pipe are installed inside the water storage tank, a fixed pipe is provided on the top, and a hose 1 is connected between the fixed pipe and the spray gun;

[0008] A horizontal plate is provided inside the equipment bin, and a ventilation window is provided on the rear end face. A blower is installed on the top of the horizontal plate, and the output end of the blower is connected to the cooling pipe through a conduit 1. A connecting pipe is installed through the top of the equipment bin, and one end of the connecting pipe is connected to the cooling pipe through a conduit 2, and the other end is connected to the spray gun through a hose 2.

[0009] Furthermore, a water inlet pipe is provided at the upper part of the side of the box body, and an observation window is provided at the front end.

[0010] Furthermore, the semiconductor refrigerator and the atomizer are installed on the bottom surface of the box body, and the cooling pipe is installed on the partition.

[0011] Furthermore, the cooling pipe is a serpentine pipe.

[0012] Furthermore, a dustproof net is installed inside the ventilation window.

[0013] Furthermore, a battery and an inverter are provided below the transverse plate.

[0014] The advantages of the utility model compared with the existing technology are: the utility model can rotate the spray barrel by extending and retracting the telescopic rod, and the angle of the spray barrel can be adjusted. The semiconductor refrigerator cools the water in the water storage tank, and the atomizer atomizes the cold water. The airflow generated by the blower is transported to the spray barrel after cooling, and drives the water mist to be sprayed toward the working area. Since the temperatures of the water mist and the airflow are both low, rapid ventilation and cooling of the working area can be achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] like Figure 1 and Figure 2As shown, a safety ventilation device for underground operations includes a box body 1, a water inlet pipe 18 is provided on the upper side of the box body 1, an observation window 19 is provided at the front end, a spray gun 2 is installed on the top of the box body 1, and casters 3 are installed on the bottom. Two supporting plates 4 are fixedly connected to the top of the box body 1, and the spray gun 2 is rotatably installed on the two supporting plates 4. A telescopic rod 5 is hinged between the spray gun 2 and the top surface of the box body 1, and a partition 6 is provided inside the box body 1. The partition 6 divides the inside of the box body 1 into a water storage bin and an equipment bin.

[0022] The telescopic rod 5 is extended and retracted to allow the spray barrel 2 to rotate around the connection between the spray barrel 2 and the support plate 4, so that the angle of the spray barrel 2 can be adjusted.

[0023] like Figure 3 As shown, a semiconductor refrigerator 7, an atomizer 8 and a cooling pipe 9 are installed inside the water storage tank, a fixed pipe 10 is provided on the top, a hose 11 is connected between the fixed pipe 10 and the spray gun 2, the semiconductor refrigerator 7 and the atomizer 8 are installed on the bottom surface of the box body 1, and the cooling pipe 9 is a serpentine pipe and is installed on the partition 6.

[0024] The semiconductor refrigerator 7 can be used to cool the water in the water storage tank, and then the gas in the cooling pipe 9 can be cooled down. The atomizer 8 atomizes the water and then enters the spray gun 2 through the fixed pipe 10 and the hose 11.

[0025] like Figure 4 As shown, a horizontal plate 12 is provided inside the equipment warehouse, a ventilation window is provided on the rear end face, a dustproof net 20 is installed inside the ventilation window, a blower 13 is installed on the top of the horizontal plate 12, a battery 21 and an inverter 22 are provided below, the output end of the blower 13 is connected to the cooling pipe 9 through a conduit 14, a connecting pipe 15 is installed through the top of the equipment warehouse, one end of the connecting pipe 15 is connected to the cooling pipe 9 through a conduit 2 16, and the other end is connected to the spray gun 2 through a hose 2 17.

[0026] The airflow generated by the blower 13 when working passes through the duct 1 14, the cooling pipe 9, the duct 2 16, the connecting pipe 15 and the hose 2 17 in sequence and then enters the spray barrel 2, and then is sprayed to the area requiring cooling through the spray barrel 2. The cooling pipe 9 can cool the airflow.

[0027] In specific use, the device is moved to an area that requires ventilation and cooling, the angle of the nozzle 2 is adjusted, the semiconductor refrigerator 7 and the blower 13 are turned on, and the atomizer 8 is turned on. The semiconductor refrigerator 7 cools the water in the water storage tank, and the atomizer 8 atomizes the cold water. The atomized water mist enters the interior of the nozzle 2, and the airflow generated by the blower 13 is transported to the nozzle 2 after cooling, driving the water mist to be sprayed toward the working area. Since the temperatures of the water mist and the airflow are both low, rapid ventilation and cooling of the working area can be achieved. The water mist is sprayed into the air, which can capture and settle suspended particles, achieve dust reduction, and improve the air quality of the working area.
