Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mine equipment, in particular to a mine wind pressure monitoring device. Background Art
[0002] In a mine, wind pressure refers to the pressure generated by the gases flowing through the mine. Measuring wind pressure is crucial because it helps miners understand the flow of gases within the mine, ensuring the proper functioning of the ventilation system and protecting miners' safety.
[0003] Currently, wind pressure is measured using devices such as wind pressure gauges, wind pressure detectors, and pressure sensors. A wind pressure gauge is a specialized instrument used to measure gas or wind pressure. Within a mine, a wind pressure gauge can be used to directly measure wind pressure and monitor airflow. The readings from the wind pressure gauge can indicate whether the ventilation system is functioning properly and ensure smooth air circulation within the mine.
[0004] The wind pressure gauges currently in use are wind tube-style wind tube wind pressure gauges, which are fan-shaped devices for detecting wind pressure. When the flowing wind in the mine enters it, it will blow the fan-shaped blades and rotate, and collect wind speed and wind pressure data through pressure sensors. However, the wind pressure gauges currently used generally have a single set of fan blades and pressure sensors for detection, and long-term operation will cause increased wear. Utility Model Content
[0005] The purpose of the present utility model is to provide a mine wind pressure monitoring device to solve the problems raised in the above background technology.
[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a mine wind pressure monitoring device, comprising an air inlet hood, an outer shell, an air outlet hood and a support leg, a first air duct is opened at one end of the interior of the outer shell, a guide plate is rotatably installed inside the first air duct, a second air duct is opened on one side of the interior of the outer shell, a first wind pressure gauge is fixed in the middle of the interior of the second air duct, a third air duct is opened on the other side of the interior of the outer shell, a second wind pressure gauge is fixed in the middle of the interior of the third air duct, the four sides of the outer bottom surface of the outer shell are connected to the support leg, and a sleeve rod is provided inside the support leg.
[0007] When using a mine wind pressure monitoring device in the present technical solution, the staff needs to first install the utility model and move the utility model into the mine to be used. After moving it inside, the staff needs to adjust the height of the four legs. Because the surface inside the mine is not necessarily flat, it is necessary to adjust the height of the four legs so that the utility model can be placed in parallel as a whole, which is convenient for better monitoring of the wind pressure. The staff screws the fastening bolts, and after screwing, loosens the inner rod inserted into the sleeve rod. After loosening, the staff pushes and pulls to change the position of the inner rod in the sleeve rod, and then adjusts the height of the overall legs. After adjustment, the fastening bolts are screwed again to fix the sleeve rod and the inner rod in the existing state. After the four legs are adjusted, the staff connects the utility model to the external power supply and the utility model can be used normally. When the flowing wind in the mine blows, the wind will directly blow into the interior of the air inlet hood, entering The wind entering the air inlet hood will gather and enter the interior of the first air duct, and then be transmitted to the interior of the second air duct through the guidance of the first air duct and the guide plate. After entering the second air duct, it will be monitored by the first wind pressure gauge installed therein. The monitored wind will be transmitted to the interior of the air outlet hood through the fourth air duct, and finally discharged from the outer shell through the air outlet hood. After the first wind pressure gauge has been used for a certain period of time, its motor will rotate the guide plate connected to the output end. The guide plate rotates to change the transmission direction of the wind, close the channel between the first air duct and the second air duct, and open the channel between the first air duct and the third air duct. In this way, the flowing wind entering the outer shell will be directly transmitted to the third air duct and monitored by the second wind pressure gauge installed in the third air duct. The motor, the first wind pressure gauge, the second wind pressure gauge and other devices in the utility model are all controlled by the program set in advance in the control panel by the staff.
[0008] Preferably, an inner rod is inserted into the sleeve rod, a bottom block is fixed to one end of the inner rod, and a fastening bolt is inserted into the outer side of the sleeve rod. The cooperation between the inner rod and the sleeve rod allows the overall length of the support leg to be changed, achieving the effect of adjusting the height position of the outer shell according to the ground so that it can be placed parallel. The provision of the fastening bolt allows the inner rod inserted into the sleeve rod to be squeezed and fastened, thereby indirectly fixing the length of the support leg.
[0009] Preferably, the bottom end of the guide plate is connected to a motor, and the motor is fixed in the middle of the outer bottom surface of the shell. By arranging the motor, the guide plate can be rotated, achieving the effect of power output and control.
[0010] Preferably, a fourth air duct is provided at the other end of the interior of the housing, and a baffle is provided inside the fourth air duct. The installation of the baffle allows the air transmitted to the fourth air duct through the second air duct and the third air duct to be separately transmitted to the interior of the air outlet cover to prevent backflow.
[0011] Preferably, one end of the outer shell is connected to an air inlet cover, and the other end of the outer shell is connected to an air outlet cover. Through the cooperation of the air inlet cover and the air outlet cover, the wind in the mine can enter and exit the inner part of the shell, achieving the effect of gathering the air in and out.
[0012] Preferably, the air inlet and outlet hoods are both provided with filters. The installation of the filters reduces dust inflow and outflow when the air in the mine enters and exits the air inlet and outlet hoods, thereby improving the monitoring accuracy of the first and second wind pressure gauges and extending their service life.
[0013] Compared with the prior art, the beneficial effects of the present invention are:
[0014] 1. The utility model is provided with two air ducts in the housing, and an air pressure gauge is installed in each of the two air ducts. In this way, the flowing air entering the housing through the air inlet cover can be guided by the guide plate to one of the air ducts to be monitored by the air pressure gauge. When the air pressure gauge in the air duct has been used for a certain period of time, the guide plate can be rotated to use the air pressure gauge in the other air duct. In this way, the two air pressure gauges are used in rotation at a regular interval to avoid damage caused by long-term operation of a single air pressure gauge. BRIEF DESCRIPTION OF THE DRAWINGS
