Description

Technical Field

[0001] The utility model relates to the technical field of coal mines, in particular to a full-section wind measuring device underground in a coal mine. Background Art

[0002] Referring to the patent document with application number "CN202222047743.7" and titled "A new ventilation volume detection device for coal mines", this patent document, through the setting of a supporting positioning mechanism, facilitates the auxiliary positioning effect of the detection head when the detection head is deeply inside the pipeline to detect the ventilation volume in the pipeline. On the premise of ensuring the stability of the detection head during detection in the pipeline, there is no need for manual labor to hold the detection head for a long time during actual detection, which greatly reduces the burden of manual operation and enhances practicality.

[0003] The existing technology enables the device to measure wind underground in coal mines through a reverse screw and a roller, and can adapt to the cross-sectional environment of most coal mines. Although the roller can change on the reverse screw after being compressed, making the device body more adaptable to the current cross-sectional environment and obtaining the wind direction of the current cross-sectional environment, the cross-sectional environment underground in coal mines is relatively complex, making it impossible for the existing technology to test extreme cross-sections, which will cause the roller to interact with the environment and get stuck, making it impossible to measure wind on extreme cross-sections, thereby affecting the wind measurement efficiency of the entire cross-section.

[0004] Therefore, we designed a full-section wind measuring device for underground coal mines. Utility Model Content

[0013] The beneficial effects of the utility model are:

[0014] 1. The utility model can perform wind measurement according to the current extreme cross-section environment by extending the end head and setting the telescopic wire tube. At the same time, the extended end head can avoid the function of wind measurement being unable to work due to narrow cross-section. The telescopic wire tube can increase the operating distance of the extended end head wind measurement work, thereby improving the efficiency of coal mine wind measurement.

[0021] Reference Figure 1-Figure 4 A full-section wind measuring device for underground coal mines includes a wind measuring machine 1. The wind measuring machine 1 is a functional device for testing the wind speed of the underground section of the coal mine in the prior art. It can facilitate the staff to understand whether the current wind speed in the underground coal mine meets the mining requirements, and provide directionality for the staff. The control end 3 is the prior art, that is, the main control unit of the wind measuring machine 1, and some functions are controlled by a remote control device. The telescopic wire tube 4 is a telescopic tube with adjustable length in the prior art, which is combined with a retractable line. The operating rod 12 is a hand-held rod for the staff in the prior art, and the length can be assembled according to the surrounding environment, so that the staff can extend the wind measuring machine 1 to a measurable section.

[0022] An extension end 2 for extending the wind measuring distance is provided on the anemometer 1. The function of the extension end 2 is to extend the measuring end of the anemometer 1 so that the anemometer 1 can measure the wind inside the restricted section outside the restricted section. A telescopic protective cover is provided at one end of the anemometer 1. The telescopic protective cover is made of stainless steel to reduce rust caused by the coal mine environment. The telescopic protective cover is mainly a protective measure under the length adjustment of the extension end 2. The extension end 2 is fixedly connected to the anemometer 1 by fasteners. The fasteners can reduce the risk of the test link hitting the wall and causing the work to be unable to proceed, and improve the connection relationship between the two. One end of the telescopic wire tube 4 passes through the telescopic protective cover and is fixedly connected to the extension end 2. The telescopic wire tube 4 is connected to the bottom end of the extension end 2, which is convenient for the extension end 2 to change its length when the length is adjusted.

[0023] The anemometer 1 is symmetrically provided with a plurality of fixed ends 5, which are auxiliary protruding surfaces and are linearly arranged on the side wall of the anemometer 1. The fixed ends 5 are provided with a port shell, which is cylindrical and has a hollow interior. One end of the port shell is fixed to the fixed end 5, and a slide groove is provided on the other end.

[0024] A compression spring 6 for reducing pressure is provided on the fixed end 5. The compression spring 6 is used to absorb the pressure brought by the aluminum alloy bracket 8 and reduce the damage to the wind measuring machine 1 caused by the extrusion force. One end of the compression spring 6 is fixedly connected to the fixed end 5. The compression spring 6 is fixed on the fixed end 5, and the other end is against the port shell. The other end passes through the slide groove, and the slide groove of the port shell limits one end of the compression spring 6. A compression shaft is provided on the port shell. The compression shaft mainly absorbs the pressure of the aluminum alloy bracket 8 and produces a telescopic action after the aluminum alloy bracket 8 is squeezed. A rotating knob 7 for rotating the compression shaft is provided on the port shell. The rotating knob 7 makes it easy for the aluminum alloy bracket 8 to produce a stretching distance between the aluminum alloy bracket 8 and the wind measuring machine 1 according to the ruggedness of the cross-sectional environment.

[0025] An aluminum alloy bracket 8 for protecting the anemometer 1 is provided on the fixed end 5. The aluminum alloy bracket 8 is a prior art and is in the shape of a long hook as a whole. It is mainly used to protect the side wall of the anemometer 1. Secondly, it cooperates with the fitting wheel 10 to offset the cross-sectional environment so that the anemometer 1 can be used to measure wind in the current environment. The compression shaft is fixedly connected to the aluminum alloy bracket 8, and the aluminum alloy bracket 8 slides in the compression shaft through a slider. The slider is a prior art and can facilitate the bottom of the aluminum alloy bracket 8 to slide up and down in the compression shaft according to extrusion.

[0026] The aluminum alloy bracket 8 is provided with a fitting wheel 10 for contacting the cross-section environment. The fitting wheel 10 is made of frosted material to improve the grip. The aluminum alloy bracket 8 is provided with multiple pressing shafts 9. The pressing shafts 9 are composed of telescopic joints and springs, and are prior art. The pressing shafts 9 are adapted to the aluminum alloy bracket 8 so that the fitting wheel 10 has a contraction effect to adapt to different wind measurement scenarios. The fitting wheel 10 is fixedly connected to one end of the pressing shaft 9. An anti-scratch plate 11 is provided at the bottom of the wind measuring machine 1. The anti-scratch plate 11 is used to protect the bottom of the wind measuring machine 1.

[0027] The working principle of the utility model is as follows: the staff splices the operating rod 12 according to the current survey environment, and then lifts the wind measuring machine 1 to make it reach the section, and adjusts the length of the extended end 2 according to the current section to improve the measurement of the wind speed inside the section. When there are stone walls on both sides of the section, the operating rod 12 can be pushed to make the fitting wheel 10 abut against the stone wall, and under continuous pushing, the fitting wheel 10 is retracted inwardly through the pressing shaft 9, and the aluminum alloy bracket 8 is retracted toward the compression shaft under the action of extrusion. At the same time, the compression shaft can be rotated micro-rotated by the rotating knob 7, so that the extended end 2 is closer to the section for wind measurement.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
