Description

Technical Field

[0001] This invention relates to the field of tunnel wind measurement equipment technology, specifically to a device and method for simultaneous multi-point full-section tunnel wind measurement. Background Technology

[0002] During the construction of gas tunnels, tunnel wind measurement is crucial for ensuring construction safety, preventing gas accumulation and explosions, protecting personnel lives, and efficiently organizing the operation of the ventilation system. Gas tunnels generally employ mechanical wind speed testing methods, using mining mechanical anemometers or measuring cups. Workers take multiple single-point measurements by hand or by mounting the anemometer on a manual telescopic device.

[0003] In existing technologies, full-section tunnel wind measurement devices require workers to repeatedly climb scaffolding when holding the instrument, increasing safety hazards. While mounting the instrument on a manual extension device avoids this, this method only measures wind speed at one location per section, requiring manual repositioning for repeated measurements. This makes it difficult to ensure all measuring points are on the same plane, and the measurement is time-dependent, with lags between measuring points significantly affecting the accuracy of the results.

By calculating the average wind speed measured by each anemometer, the accuracy of tunnel wind measurement operations is improved.

[0022]

[0023] in, The average wind speed at the measured cross-section is the final statistical quantity calculated from wind speeds at multiple measurement points. 'n' represents the number of anemometers, i.e., the total number of measurement points used to measure the wind speed at this cross-section, or the number of anemometers involved in the measurement. V iThen, it represents the wind speed value measured by the i-th anemometer. i ranges from 1 to n, corresponding to the wind speed data measured by different anemometers. By summing and averaging the wind speeds at these different measuring points, the cross-sectional average wind speed is obtained.

[0024] The loading and unloading mechanism 7 includes a rotating rod 701, which provides an installation position. The output end of the rotating rod 701 is fixedly connected to the output end of the rotation controller 6. The rotation controller 6 can drive the rotating rod 701 to rotate, which in turn drives the telescopic controller 8, the automatic telescopic column 10, and the outer anemometer 11 to rotate, thereby adjusting the angle of the outer anemometer 11. A driving gear ring 702 is fixedly connected to the outside of the rotating rod 701. A stabilizing gear ring 703 is rotatably connected to the outside of the rotating rod 701 near the rotation controller 6. A rotating groove ring 704 is rotatably connected to the outside of the rotating rod 701 away from the stabilizing gear ring 703. Multiple through grooves 705 are provided on the outer edge of the fixed sub-plate 5. The through grooves 705 and the stabilizing gear ring 704 are connected to the rotating sub-plate 5. The engagement of the gear ring 703 maintains the stability of the rotation controller 6, preventing it from rotating when the rotating rod 701 rotates. An internal gear post 706 is mounted on the outside of the gear ring 702, and the interior of the internal gear post 706 is meshed with the exterior of the gear ring 702. When the rotating rod 701 rotates, it drives the gear ring 702 to rotate, thereby causing the internal gear post 706 to rotate. Rotating internal gear rings 707 are rotatably connected to both sides of the internal gear post 706. These rotating internal gear rings 707 abut against the inner side of the fixed sub-plate 5, improving the stability of the internal gear post 706 and preventing it from wobbling inside the fixed sub-plate 5. The external fixed connection includes a connecting rod 708, which serves as the mounting rod. Multiple fixing rings 709 are fixedly connected to the side of the fixing plate 5 away from the bolt group 4. These fixing rings 709 also serve as the mounting rings. A sliding groove 710 is provided inside each fixing ring 709. A fixing cylinder 711 is fixedly connected to the top of the fixing ring 709, providing the mounting position. A through sliding groove 712 is provided at the bottom of the fixing cylinder 711. A sliding inner block 713 is slidably connected inside the fixing cylinder 711. A retaining plate 714 is fixedly connected to the bottom of the sliding inner block 713. The sliding groove 710 prevents the retaining plate 714 from sliding out of the fixing ring 709. The retaining plate 714 can slide within the through sliding groove 712. The fixing cylinder 711... An internal tension spring 715 is installed, which can drive the sliding inner block 713 to reset. A driving inner rod 716 is fixedly connected to the middle of the sliding inner block 713. The driving inner rod 716 serves as an installation tool and is engaged with the stabilizing gear ring 703 through a toothed groove 705. The top of the connecting rod 708 is fixedly connected to the bottom of the telescopic controller 8. The outer side of the clamping plate 714 is located inside the rotating groove ring 704.

One end of the tension spring 715 is fixedly connected to the inside of the fixed cylinder 711, and the other end of the tension spring 715 is fixedly connected to the end of the sliding inner block 713 near the round handle 717. One end of the driving inner rod 716 is fixedly connected to the round handle 717.The round handle 717 is easy for operators to press, causing the inner rod 716 to slide and connect inside the fixed cylinder 711. The locking plate 714 is slidably connected inside the through groove 712 and the sliding groove 710.

[0025] The folding mechanism 9 includes two sliding mounting slots 901, which provide sliding space. The two sliding mounting slots 901 are respectively formed inside the two sides of the fixed base plate 1. Two sliding mounting blocks 902 are slidably connected inside the sliding mounting slots 901. The sliding mounting blocks 902 provide mounting positions and allow them to slide within the sliding mounting slots 901. A mounting post 903 is fixedly connected to the top of each sliding mounting block 902, allowing it to be mounted on the block. A connecting post 904 is fixedly connected between the two sliding mounting blocks 902, serving to... The connecting function allows two sliding mounting blocks 902 to be connected together. A ball head 905 is fixedly connected to one side of the top of the mounting column 903. A connecting rod 906 is rotatably connected to the outside of the ball head 905. The ball head 905 allows the connecting rod 906 to rotate at multiple angles. A rotating column 907 is rotatably connected to the outside of the three-section automatic telescopic mechanism 2. The rotating column 907 serves as a connector. The side of the rotating column 907 away from the three-section automatic telescopic mechanism 2 is rotatably connected to the top of the mounting column 903 away from the ball head 905. The end of the connecting rod 906 away from the ball head 905 is rotatably connected to the top of the folding plate 13.

[0026] Please see the appendix Figure 11 - Appendix Figure 20 A wind measurement method for a multi-point, full-section tunnel wind measurement device at the same time includes the following steps: Step 1: Select relevant wind speed measuring points based on project requirements and the size and shape of the tunnel cross-section.

[0027] Step 2: After the wind speed measuring points in Step 1 are determined, the device of the present invention is placed in front of the tunnel section. At this time, the outer anemometer 11, the automatic telescopic column 10, the rotation controller 6 and the telescopic controller 8 are close to the measuring section. The intersection point of the middle part of the fixed base plate 1 of the present invention and the outer contour of the tunnel is taken as the coordinate origin O (0,0) to establish a two-dimensional coordinate system. Then each measuring point has corresponding coordinates (xi,yi).

[0028] Step 3: After establishing the coordinate system in Step 2, the fixed sub-plate 5 is raised to a certain position on the cross-section using the three-section automatic telescopic mechanism 2. At this time, the structure on the fixed sub-plate 5 will also be raised to a certain position on the cross-section, and the center point of the fixed sub-plate 5 is taken as (0, h). Subsequently, the rotation controller 6 rotates the measuring unit composed of the outer anemometer 11, the automatic telescopic column 10, and the telescopic controller 8 by a certain angle. Finally, the telescopic controller 8 controls the automatic telescopic column 10 to extend to a fixed position, such as... Figure 20 As shown, this allows the device to be installed in the tunnel cross-section and the wind speed in the tunnel cross-section to be measured.

[0029] Working principle: When disassembling the telescopic controller 8, automatic telescopic column 10, and external anemometer 11, first push the round handle 717, which will drive the sliding inner block 713 and the locking plate 714 to move. Then, the locking plate 714 can slide out of the rotating groove ring 704. At this time, the locking plate 714 will no longer block the removal of the rotating rod 701. Then, the rotary controller 6 and the rotating rod 701 can be pulled outward, which will then drive the gear ring 702 from the mounting inner gear column 706 and the rotating rod 701. Pulling out the internal gear ring 707 allows the mounting internal gear column 706 and the rotating internal gear ring 707 to be removed from the inside of the fixed sub-plate 5. At this point, the connecting rod 708, telescopic controller 8, automatic telescopic column 10, and outer anemometer 11 can be detached from the inside of the fixed sub-plate 5. When installing the connecting rod 708, first insert the mounting internal gear column 706 into the inside of the fixed sub-plate 5, align the rotating internal gear ring 707 and the inside of the mounting internal gear column 706 with the toothed groove 705, and align the inner teeth. At this point, insert the rotating rod 701 into the toothed groove 705, simultaneously driving the toothed ring 702 through the toothed groove 705 and inserting it into the mounting inner toothed post 706. Insert the stabilizing toothed ring 703 into the toothed groove 705. Then, release the round handle 717. Under the tension of the tension spring 715, pull back the sliding inner block 713, thereby pulling back the retaining plate 714. The retaining plate 714 then slides through the sliding groove 710 into the groove of the rotating ring 704. This completes the installation of the connecting rod 708, and the rotation is then initiated. When the controller 6 is in operation, due to the limiting of the stabilizing gear ring 703, the rotating controller 6 will not rotate along with the rotating rod 701 when the rotating controller 6 drives the rotating rod 701 to rotate. This will drive the rotating rod 701 to rotate, thereby driving the gear ring 702 to rotate, and driving the mounting inner gear column 706 to rotate. This will then drive the connecting rod 708 to rotate, and drive the telescopic controller 8, the automatic telescopic column 10, and the outer anemometer 11 to rotate, thereby adjusting the angle of the outer anemometer 11. When folding and storing the device, first remove the telescopic controller 8, automatic telescopic column 10, and outer anemometer 11, and then activate the three-section automatic telescopic mechanism 2. The retraction of the three-section automatic telescopic mechanism 2 lowers the fixed sub-plate 5. At this time, the three-section automatic telescopic rod 3 retracts, causing the three-section automatic telescopic mechanism 2 to tilt and rotate towards the fixed base plate 1. When the three-section automatic telescopic mechanism 2 rotates downwards, it moves the folding mechanism 9 towards the battery 14 and allows it to rotate. This, through the connecting column 904, moves the two sliding mounting blocks 902 towards the battery 14. At this time, the ball head 905 pulls the connecting rotating rod 906 towards the battery 14, thus... The folding plate 13 is able to rotate upwards, thereby folding it up to reduce its storage volume and storing the battery 14 and digital display control device 15 inside, thus protecting them. When unfolding the three-section automatic telescopic mechanism 2, the three-section automatic telescopic rod 3 is activated first. The output end of the three-section automatic telescopic rod 3 extends out and drives the three-section automatic telescopic mechanism 2 to rotate upwards, making it stand upright. At this time, the three-section automatic telescopic mechanism 2 drives the rotating column 907 to move away from the battery 14 and drives the mounting column 903 to move away from the battery 14. This allows the connecting rotating rod 906 to push the folding plate 13 to unfold, thereby increasing the area of ​​the fixed base plate 1 and improving stability. When setting up the device, first, based on the project requirements and considering factors such as the size and shape of the tunnel cross-section, select relevant wind speed measuring points, such as... Figure 16 As shown. Next, the device of the present invention is arranged in front of the tunnel cross-section. The outer anemometer 11, the automatic telescopic column 10, the rotation controller 6, and the telescopic controller 8 form a measurement module. The measurement module is close to the measurement cross-section. A two-dimensional coordinate system is established with the intersection point of the middle part of the fixed base plate 1 of the present invention and the outer contour of the tunnel as the origin O0,0. Then each measuring point has corresponding coordinates xi,yi, as shown. Figure 17 As shown. Next, the measuring module is raised to a certain position on the cross-section using the three-section automatic telescopic mechanism 2, and the center point of the fixed sub-plate 5 is taken as 0,h, as shown. Figure 18 As shown. Subsequently, the rotation controller 6 rotates the measuring unit, which consists of the telescopic controller 8, the automatic telescopic column 10, and the outer anemometer 11, by a certain angle, as shown. Figure 19 As shown. Finally, the telescopic controller controls the wind measurement telescopic rod to extend to a fixed position, as... Figure 20 As shown, the installation of the device is now complete.
