Description

Technical Field

[0001] The utility model relates to the technical field of wind speed detection devices, in particular to a wind speed detection device for mine shaft and tunnel ventilation. Background Art

[0002] A mine specifically refers to an area rich in valuable minerals such as mineral materials and oil, but they are often buried deep inside a mountain or underground and need to be excavated before they can be mined. Because the mines are deep and long, for safety reasons, it is necessary to monitor the wind speed and direction in different areas of the mines in real time. Wind speeds that are too fast or too slow are not good, and should be stabilized at a certain value to ensure smooth airflow in the surrounding working environment.

[0003] In the past, wind speed detection devices were often fixed directly on the top of the mine, and the length of accessories such as brackets was mostly determined to be unchangeable. If the detection height changed, it would be difficult to make changes in time, requiring workers to manually operate in time, which was time-consuming and labor-intensive, and lacked timeliness.

[0004] Now, a new type of wind speed detection device for mine shaft ventilation is proposed to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a wind speed detection device for mine shaft ventilation to solve the problem of fixed detection height in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wind speed detection device for mine shaft ventilation, comprising a cross plate and a cross beam, a slideway is provided between the two sides of the front end of the cross beam, and the cross plate is movably inserted in the slideway, a bracket is fixed at the central groove at the front end of the cross plate, and a micro motor is installed on the left side of the bracket, a mounting plate is movably connected between the two sides inside the bracket, and a motor is installed at the upper right corner inside the mounting plate, a side gear is movably connected to the right side of the top of the mounting plate, and a main gear is movably connected to the left side of the top of the mounting plate, a screw rod is longitudinally connected between the main gear and the mounting plate, and a sleeve is sleeved at the bottom of the screw rod, an anemometer is installed at the bottom of the sleeve, a guide rod is welded at the front end above the screw rod, and a sleeve block is welded at the upper left side of the front end of the mounting plate.

[0011] Preferably, the bottom of the electric roller is embedded in the limiting rail, and the electric roller can slide left and right along the inner wall of the limiting rail.

[0012] Preferably, a shell is fixedly connected to the center of the top of the cross beam, and an air hole is opened in the upper left corner of the rear of the shell, a blower is installed on the left side of the top of the outer shell, and a fan is installed in the upper right corner of the rear of the shell, a box body is welded to the right side of the top of the shell, and air-permeable nets are installed inside both sides of the box body, a cover plate is inserted above the box body, and a tube body is fixedly inserted between the top of the cover plate and the air inlet of the fan, and a screen frame is welded to the bottom of the cover plate.

[0013] Preferably, the screen frame is placed vertically in the box, and the air-permeable net is symmetrically fixed in the inner walls on both sides of the box.

[0014] Compared with the prior art, the utility model has the following beneficial effects: the wind speed detection device for mine shaft ventilation not only realizes the adjustment of the height of the detection device and the change of the horizontal position of the detection device, but also realizes the cleaning of the anemometer;

[0015] (1) An anemometer is installed at the bottom of the casing. After the motor is started, the side gear is rotated to turn the main gear on the left. Since the guide rod is embedded in the casing block, when the main gear rotates to engage the screw rod, it can pass through the circular notch of the mounting plate and press down the screw rod with the anemometer.

The dirt on its surface is blown away by the blower and injected into the box from the pipe body through the suction of the fan. The screen frame at the bottom of the closed cover is also embedded in the box to filter garbage, and the excess air is discharged from the air permeable net on the side.
