Description

[0002] The intelligent construction of mine ventilation systems is an important part of future smart mine construction. Accurate monitoring of ventilation parameters such as tunnel wind speed and wind pressure is an important prerequisite for ensuring the safety of tunnel ventilation systems and realizing the intelligence of ventilation systems. The existing tunnel wind speed measurement methods are difficult to meet the accuracy requirements of intelligent construction.

[0003] At present, mine ventilation air volume detection is mostly carried out manually, which requires manual hand-held wind speed measuring devices to be measured in the mine tunnel. At the same time, in order to improve the accuracy of the measurement results, it is necessary to measure multiple points on the same cross-section of the mine tunnel. However, the manual hand-held method cannot guarantee accuracy on the same cross-section, which affects the measurement accuracy. At the same time, in order to determine whether the ventilation system is running smoothly, wind speed measurements need to be performed frequently, which undoubtedly wastes manpower and material resources and affects the judgment on whether the mine ventilation system is running smoothly.

[0027] The following is combined with Figure 1-4 This application is described in further detail.

[0028] The embodiment of the present application discloses a precise wind speed measurement device for an underground tunnel, the device comprises a bracket 1 and a plurality of slide rails 2, the bracket 1 is placed in the tunnel, the bracket 1 is composed of a plurality of vertical rods 11 and a plurality of horizontal rods 12, the slide rails 2 are arranged in the two side walls of the tunnel, the slide rails 2 are arranged from top to bottom, the lowest ends of the slide rails 2 are arranged at intervals in the vertical direction and are located on the same vertical plane, and the top ends of the slide rails 2 are arranged at intervals in the length direction of the tunnel; a slide rod 3 is slidably connected in the two corresponding slide rails 2, and pulleys are rotatably connected at both ends of the slide rod 3, the rotation axis of the pulley is arranged in the horizontal direction, and the pulley is inserted into the slide rail 2, so that the slide rod 3 can slide along the slide rail 2; a plurality of connecting rods 31 are arranged on the slide rod 3, and the plurality of connecting rods 31 are arranged at intervals in the length direction of the slide rod 3, and a wind speed detector 4 is installed on each connecting rod 31; at the same time, a driving component 5 for driving the slide rod 3 to slide along the slide rail 2 is provided on the bracket 1.

[0029] When it is necessary to detect the wind speed in the tunnel, the slide bar 3 is driven by the driving component 5 to slide down the slide rail 2, so that multiple wind speed detectors 4 are distributed at different positions of the same cross-section of the tunnel for wind speed detection; further, the slide bar 3 can be lowered and the detection data can be transmitted remotely by remote control or data transmission, which saves a lot of manpower and material resources, and the measurement results are more accurate; after the measurement is completed, the slide bar 3 slides to the top of the slide rail 2 again through the driving device, and the wind speed detector 4 is stored without hindering the operation of pedestrians or machinery; at the same time, since the top of the slide rail 2 is at a different position, when the wind speed detector 4 is stored, its volume share in the same cross-section is reduced, thereby reducing the impact on the tunnel wind flow and transportation.

[0030] In the embodiment of the present application, the driving assembly 5 includes a roller 51, a motor 52 and a pull rope 53. The roller 51 is rotatably connected to the top of the bracket 1, and the rotation axis of the roller 51 is arranged in the horizontal direction. One end of the pull rope 53 is wound and fixedly connected to the roller 51, and the other end of the pull rope 53 is fixedly connected to the slide bar 3. The motor 52 is used to drive the roller 51 to rotate; when the slide bar 3 needs to be lowered, the roller 51 is rotated to release the pull rope 53, and the slide bar 3 begins to slide down to the end point of the slide rail 2 under the action of gravity; after the measurement is completed, the motor 52 drives the roller 51 to rotate to reel in the pull rope 53. During this process, the pull rope 53 lifts the slide bar 3 to the top of the slide rail 2.

[0031] In order to prevent the motor from being damaged due to over-operation, a contact sensor 13 is provided at the top of the cross bar 12 at the top of the bracket 1. When the cross bar 12 abuts against the contact sensor 13, the motor 52 stops operating.

[0032] The present application also provides a method for accurately measuring wind speed in an underground tunnel, comprising the following steps:

[0033] S1. Set up the bracket of the wind speed measuring device in the lane and ensure that the vertical pole will not block the passage of the lane;

[0034] S2. Slide rails are arranged on both side walls of the laneway, and slide bars with wind speed detectors are installed in the slide rails. It should be noted that three slide rails are arranged on both sides, and the shapes of the two opposite slide rails are the same, and the same slide bar is installed;

[0035] S3, connecting the slide bar to the pull rope in the drive assembly on the bracket;

[0036] S4. When the wind speed in the lane needs to be detected, the motor drives the roller to rotate, releases the pull rope, and lowers the slide bar. At this time, multiple wind speed detectors detect the wind speed;

[0037] S5. After the inspection is completed, the motor drives the roller to reel in the pull rope, thereby lifting the slide bar and restoring the smoothness of the tunnel.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
