For example, some devices may not be able to accurately measure key parameters such as temperature, humidity, and harmful gas concentration in the ventilation duct, resulting in the inability to timely discover and deal with potential safety hazards. In addition, the operation process of some devices is complicated and requires frequent intervention by professionals, which not only increases labor costs but also may affect production efficiency. At the same time, maintenance difficulties are also an important factor restricting the application of traditional ventilation detection devices. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 3 As shown, a detection device for ventilation of phosphate mines includes a ventilation duct 1, an air guide hood 2, an air guide plate 3 and a pressure sensor 4. The air guide hood 2 is arranged in the ventilation duct 1; the air guide hood 2 is provided with a vent 21 and an air collecting port 22, the air guide plate 3 is arranged on one side of the air collecting port 22, and a connecting column 5 is arranged between the air guide plate 3 and the air guide hood 2; a gap 51 is arranged between the air guide hood 2 and the air guide plate 3. The design of the air guide hood 2 and the air guide plate 3 enables the device to effectively regulate the air flow in the ventilation duct 1. The vent 21 and the air collecting port 22 on the air guide hood 2 enable the air to flow along a specific path, and the air guide plate 3 can further guide the direction of the air.

[0021] A temperature and humidity sensor 6 and a gas concentration detector 7 are respectively arranged on both sides of the gap 51; and the temperature and humidity sensor 6 and the gas concentration detector 7 are respectively connected to the inside of the ventilation duct 1; the temperature and humidity sensor 6 and the gas concentration detector 7 are arranged to monitor the temperature, humidity and toxic gas components in the ventilation duct 1 in real time to ensure the safety and health of the working environment.

[0022] The pressure sensor 4 is arranged on the side wall of the air guide plate 3 and close to the air collecting port 22; an axial flow fan 11 is arranged on the other side of the air guide plate 3, and a filter plate 12 is connected to the other end of the axial flow fan 11. The filter plate 12 is installed in the ventilation duct 1, and a gas detection sensor 14 is arranged outside the filter plate 12.

[0023] By arranging the pressure sensor 4 on the side wall of the air guide plate 3 and close to the air collecting port 22, the pressure change in the ventilation duct 1 can be accurately detected. When the pressure is abnormal, the ventilation volume can be adjusted by adjusting the operating state of the axial flow fan 11 to maintain the pressure stability in the ventilation duct 1. At the same time, the toxic gas in the air is filtered through the filter plate 12, and the quality of the filtered air is detected by the gas detection sensor 14 to ensure that the air entering the phosphate mine meets the safety standards.

[0024] like Figure 2 and Figure 3 As shown, the wind guide plate 3 is surrounded by inclined plates 31, and the inclined plates 31 are used for dispersing ventilation.

[0025] By arranging the inclined plates 31 around the air guide plate 3, the ventilation can be effectively dispersed. When the air flows through the air guide plate 3, the inclined plates 31 can guide the air to diffuse around, making the ventilation more uniform, reducing dead angles and vortex phenomena, and improving the ventilation effect.

[0026] like Figure 2 and Figure 3 As shown, a cleaning mechanism is provided in the ventilation duct 1, and the cleaning mechanism includes a cleaning brush 82, a power device 8, a screw rod 81 and a collecting box 9; the power device 8 passes through the ventilation duct 1 and is connected to the screw rod 81, the cleaning brush 82 is connected to the side wall of the filter plate 12, and both ends of the cleaning brush 82 are installed on the screw rod 81; the collecting box 9 is arranged in the ventilation duct 1 and is located below the cleaning brush 82.

[0027] The cleaning mechanism can automatically clean the impurities and particles accumulated on the filter plate 12. The power device 8 drives the screw 81 to rotate, and the cleaning brush 82 moves on the side wall of the filter plate 12 to effectively remove the impurities attached to the filter plate 12, so as to keep the filter plate 12 unobstructed and the filtering effect.

[0028] like Figure 2 and Figure 3 As shown, a slider 91 is provided at the bottom of the collecting box 9 , a slide groove 13 is provided in the ventilation duct 1 , and the slider 91 is slidably provided in the slide groove 13 .

[0029] By setting the slide block 91 to cooperate with the slide slot 13, the collection box 9 can slide easily along the slide slot 13, so that it is convenient for maintenance personnel to clean or replace it. This design makes the cleaning work simple and fast, and improves the maintenance efficiency.

[0030] like Figure 2 and Figure 3 As shown, a handle 92 is provided on the side wall of one side of the collecting box 9 .

[0031] By providing the handle 92, the maintenance personnel can easily grasp and move the collection box 9, whether taking it out of the ventilation duct 1 for cleaning or putting it back to its original position, thereby improving the cleaning efficiency.

[0032] Working principle of the utility model: When the device starts working, the axial flow fan 11 starts, sucks in the air in the mine and pushes it into the ventilation duct 1. The air first flows to the air collecting port 22 through the vent 21 of the air guide cover 2. After passing through the air collecting port 22, it contacts the air guide plate 3, and the gas pressure is detected by the pressure sensor 4 arranged on the air guide plate 3. The gas pressure is adjusted by the axial flow fan 11 to maintain the pressure stability in the ventilation duct 1. After contacting the air guide plate 3, the gas flows out from the gap 51. At this time, the temperature and humidity sensors 6 and the gas concentration detector 7 arranged on both sides of the gap 51 can monitor the temperature, humidity and harmful gas concentration in the ventilation duct 1 in real time, and feed the data back to the control system. If any abnormal parameters are detected, the control system will take corresponding measures, such as adjusting the speed of the axial flow fan 11 or triggering an alarm to ensure the safety and health of the working environment. Under the action of the axial flow fan 11, the gas is filtered through the filter plate 12, and the toxic substances and particles such as magazines are filtered out. At this time, the gas detection sensor 14 arranged outside the filter plate 12 detects the quality of the filtered air to ensure that the air entering the phosphate mine meets the safety standards. When too many impurities are attached to the filter plate 12, the power device 8 drives the screw 81 to rotate, driving the cleaning brush 82 to move on the side wall of the filter plate 12 to brush off the accumulated impurities. The power device 8 is preferably a rotary motor. The impurities brushed off fall into the collection box 9 below. The staff can pull the handle 92 to pull out the collection box 9 set in the slide 13, which is convenient for cleaning and improves cleaning efficiency.

[0033] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
