Description
Technical Field
[0001] This utility model relates to the field of anemometer technology, specifically an anemometer for measurement in mines. Background Technology
[0002] When measuring wind speed in complex environments such as mines, traditional anemometers often fail to meet practical needs due to the unique working conditions. The confined space and complex, varied terrain within mines increase the difficulty of carrying and operating equipment. Furthermore, ventilation conditions within mines are crucial for ensuring miners' safety, making accurate wind speed measurement a key step in evaluating the effectiveness of ventilation systems.
[0003] However, existing anemometers have several major problems: traditional anemometers lack effective drop protection and are easily damaged in environments like mines where falls are common, leading to measurement interruptions or data loss; traditional anemometers are not very sensitive to changes in wind direction and cannot ensure that the measuring fan axis is perfectly parallel to the airflow direction, which can cause deviations in wind speed measurement data and affect the evaluation results of ventilation systems; some anemometers with wind vanes are large and not easy to carry and use in space-constrained places like mines, and these components cannot be effectively stored when not in use, making them prone to damage. Therefore, a new type of anemometer for measurement in mines is needed to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide a mine anemometer that has the advantages of being drop-proof, accurate in measurement, portable and easy to operate, and solves the problems of traditional anemometers being easily damaged, difficult to accurately measure wind speed and inconvenient to carry in complex mine environments.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a wind speed meter for measuring in a mine, comprising a wind speed meter body and a protective sleeve, wherein a drop-proof strip is provided on the side end face of the wind speed meter body, and a wind vane is provided on the top of the front end face of the wind speed meter body;
[0006] The protective sleeve is fitted over the outside of the anemometer body and is interference-fitted to it. The front end of the anemometer body is equipped with a measuring fan, a display screen, and control buttons. The wind vane includes a fixed base, a sliding sleeve, a sliding rod, a pointing rod, an arrow, and an arrow tail. The fixed base is fixedly installed on the front end face of the anemometer body. The front end face of the anemometer body is provided with a screw hole, and the fixed base is installed in the screw hole. The left and right sides of the sliding sleeve are provided with damping shafts that are rotatably connected to the fixed base. The sliding rod is installed inside the sliding sleeve and is slidably connected to it. The pointing rod is installed on the top of the sliding rod and is rotatably connected to it through a bearing. The arrow and arrow tail are respectively installed on the left and right sides of the pointing rod.
[0007] As a preferred embodiment of the present invention, a positioning groove corresponding to the shape of a wind vane is provided on the front end face of the anemometer body.
[0008] As a preferred embodiment of the anemometer for measuring in mines according to this utility model, the bottom of the positioning groove is provided with a magnet that is attracted and cooperates with the wind vane.
[0009] As a preferred embodiment of the anemometer for measuring in mines according to this utility model, a laser light is provided on the top of the anemometer body near the wind vane, and the number of laser lights is two.
[0010] As a preferred embodiment of the anemometer for measuring in mines according to this utility model, the lower end face of the arrow is provided with a light guide plate that cooperates with the laser lamp.
[0011] As a preferred embodiment of the present invention, a mine-use anemometer has a groove on the side end face of the anemometer body that mates with a drop guard strip. The drop guard strip is made of silicone material, has a cavity inside, and has an exhaust hole at the bottom.
[0012] As a preferred embodiment of the anemometer for measuring in mines according to this utility model, the inner wall of the anti-fall strip is uniformly provided with supporting ribs, and the side wall of the supporting rib is provided with through holes.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This utility model solves the problem of easy fall damage in the mining environment through the synergistic effect of the anti-fall strip, protective cover and internal buffer structure. The anti-fall strip is made of silicone material and has a cavity, vent hole and support rib inside. When falling, the cavity is compressed and deformed and slowly releases air through the vent hole to form damping buffer and reduce rebound impact. The support rib and through hole maintain the structural strength and avoid excessive deformation failure. The protective cover tightly wraps around the main body to provide an extra layer of protection. At the same time, the weather vane can be folded along the damping pivot and put into the positioning slot and fixed by magnetic adsorption. This solves the problems of component shaking, collision damage and large space occupation when carrying, making the equipment compact and portable and adaptable to the narrow and complex environment of the mine.
[0015] 2. The wind vane of this utility model achieves height adjustment through a sliding sleeve and a sliding rod, and combines a bearing rotation structure to flexibly point to the wind direction, so that the axis of the measuring fan is accurately matched with the airflow direction. Two sets of laser lights work together with the light guide plate below the arrow. When the laser is projected onto the light guide plate and diffuses along its side, it intuitively prompts the user to adjust the orientation of the equipment to ensure that the fan axis is parallel to the wind direction. This solves the problem of inaccurate wind speed data caused by wind deviation in traditional equipment. This design significantly improves the measurement reliability in irregular airflow environments in mines. Attached Figure Description

[0024] Please see Figures 1-7 A mine anemometer for measuring wind speed includes an anemometer body 1 and a protective sleeve 2. The side end face of the anemometer body 1 is provided with a drop protection strip 3, and the top of the front end face of the anemometer body 1 is provided with a wind vane 4 that is movably connected.
[0025] The protective sleeve 2 is fitted onto the outside of the anemometer body 1 and is interference-fitted to it. The front end of the anemometer body 1 is provided with a measuring fan 101, a display screen 102 and a control button 103. The wind vane 4 includes a fixed base 401, a sliding sleeve 402, a sliding rod 403, a pointing rod 404, an arrow 406 and an arrow tail 405. The fixed base 401 is fixedly installed on the front end face of the anemometer body 1. The front end face of the anemometer body 1 is provided with a screw hole 105. The fixed base 401 is installed in the screw hole 105. The left and right sides of the sliding sleeve 402 are provided with damping shafts 4021 that are rotatably connected to the fixed base 401. The sliding rod 403 is installed in the sliding sleeve 402 and slidably connected to it. The pointing rod 404 is installed on the top of the sliding rod 403 and rotatably connected to it through a bearing. The arrow 406 and the arrow tail 405 are respectively installed on the left and right sides of the pointing rod 404.
[0026] The anemometer body 1 is protected by the anti-fall strip 3 to prevent it from being damaged when it falls. The wind vane 4 indicates the current wind direction, making the axis of the measuring fan 101 more accurately match the wind direction. The foldable wind vane 4 structure allows it to be folded back to the front of the anemometer body 1 when not in use, reducing the space occupied and preventing damage to the wind vane 4. The design of the slide rod 403 and the sliding sleeve 402 makes its height adjustable.
[0027] Furthermore, the front end face of the wind gauge body 1 is provided with a positioning groove 106 corresponding to the shape of the wind vane 4.
[0028] After the wind vane 4 is used, the slide rod 403 can be retracted into the slide sleeve 402. The slide sleeve 402 then flips forward along the damping shaft 4021, and the wind vane 4 can be inserted into the positioning groove 106, providing a certain storage space for the wind vane 4. This allows the entire wind gauge to be stored in the protective cover 2, making it easy to carry and less likely to damage the wind vane 4.
[0029] Furthermore, the bottom of the positioning groove 106 is provided with a magnet 1061 that is attracted and engaged with the wind vane 4.
[0030] The wind vane 4 is attracted by magnet 1061, thereby preventing the arrow 406 and arrow tail 405 of the wind vane 4 from shaking during the carrying process, which would cause abnormal noise in the equipment. It can also prevent the arrow 406 and arrow tail 405 from lifting up during the insertion and removal of the protective cover 2 of the wind gauge body 1, which would damage the wind vane 4.
[0031] Furthermore, two laser lights 107 are installed on the top of the anemometer body 1 near the wind vane 4.
[0032] The line connecting the center points of the two sets of laser lights 107 is parallel to the axis of the measuring fan 101. When both sets of laser lights 107 are shining on the lower end face of arrow 406, it proves that the axis of the measuring fan 101 is parallel to the wind direction, and the maximum wind force under the current environment can be measured.
[0033] Furthermore, a light guide plate 407 is provided on the lower end face of arrow 406 to cooperate with laser lamp 107.
[0034] The light generated by the laser lamp 107 is laterally transmitted through the light guide plate 407, which emits a bright light, making it easy to quickly determine whether the laser lamp 107 is shining on the lower end of the arrow 406, and making it easy to quickly adjust the orientation of the wind gauge body 1.
[0035] Furthermore, the side end face of the wind gauge body 1 is provided with a groove 104 that cooperates with the anti-fall strip 3. The anti-fall strip 3 is made of silicone material, and a cavity 301 is provided inside the anti-fall strip 3. An exhaust hole 303 is provided at the bottom of the anti-fall strip 3.
[0036] The elastic anti-fall strip 3, combined with the cavity 301 structure, effectively protects the anemometer body 1 when it falls. In addition, with the bottom vent 303 structure, when the anemometer body 1 hits the ground, the anti-fall strip 3 slowly releases air through the vent 303, forming a damping effect, thereby reducing the rebound height of the anemometer body 1 after landing and further improving the protective effect.
[0037] Furthermore, the inner wall of the anti-fall strip 3 is uniformly provided with support ribs 302, and the side wall of the support ribs 302 is provided with through holes 3021.
[0038] The support ribs 302 enhance the structural strength of the anti-fall strip 3, preventing excessive elastic deformation of the anti-fall strip 3 when it falls, thus avoiding loss of protective effect. The design of the through hole 3021 allows all the air inside the anti-fall strip 3 to be discharged through the vent hole 303 at the bottom.
[0039] When using this anemometer, to measure wind speed, remove the anemometer body 1 from the protective sleeve 2, flip the wind vane 4 outwards, and pull the slider 403 using the lifting button 4041 to slide it up and down within the sliding sleeve 402 to adjust the height. The arrow 406 and arrow tail 405 at the top of the pointer rod 404 indicate the wind direction. Adjust the orientation of the anemometer body 1 according to the wind direction. Two sets of laser lights 107 near the wind vane 4 on the top of the anemometer body 1 can be used. When the light from the laser lights 107 shines on the light guide plate 407 at the lower end of the arrow 406, it indicates that the axis of the measuring fan 101 is parallel to the wind direction, at which point the maximum wind force can be measured. During the measurement process, the measuring fan 101 at the front end of the anemometer body 1 is used to measure wind speed, and the measurement data will be displayed. On the display screen 102, after the measurement is completed, the slider 403 is retracted into the sliding sleeve 402, and then the sliding sleeve 402 is rotated forward along the damping shaft 4021, so that the wind vane 4 is inserted into the positioning groove 106 corresponding to the shape of the front end face of the anemometer body 1. The magnet 1061 at the bottom of the positioning groove 106 will attract the wind vane 4 to prevent it from shaking. Finally, the anemometer body 1 is reinserted into the protective sleeve 2 for carrying. During the entire use, the silicone anti-drop strip 3 set in the slot 104 on the side end face of the anemometer body 1, its internal cavity 301 and the exhaust hole 303 structure at the bottom, as well as the support ribs 302 with through holes 3021 evenly arranged on the inner wall, can effectively protect the anemometer body 1 and reduce the risk of damage when it falls.
[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
