Description

Technical Field

[0001] The present disclosure relates to the technical field of wind speed measurement, and more precisely, to a detection tool for measuring the wind speed of a breeze in a tunnel. Background Art

[0002] There are three types of anemometers currently available in my country, with the following ranges for measuring wind speed: low-speed anemometers are used when the wind speed is 0.3-5 m / s; medium-speed anemometers are used when the wind speed is 0.5-10 m / s; and high-speed anemometers are used when the wind speed is 0.8-25 m / s. Therefore, when the wind speed in the mine is less than 0.3 m / s, the three existing anemometers cannot accurately measure the wind speed.

[0003] In existing technology, measuring wind speeds below 0.3 m / s in underground tunnels typically requires two people. The measurement method involves first measuring the distance to be measured, then one person standing upwind releases smoke, while the other stands downwind and records the time it takes for the wind to travel that distance. Finally, the wind speed in that tunnel is calculated. This method, requiring two people to measure wind speeds, is labor-intensive and requires two people to work together, complicating the measurement process and affecting the accuracy of the wind speed measurements.

[0034] In this document, “equal”, “same”, etc. are not strictly limited in a mathematical and / or geometric sense, but also include errors that can be understood by those skilled in the art and are allowed in manufacturing or use.

[0035] The present disclosure relates to a detection tool for measuring breeze speed in a tunnel, the detection tool comprising a breeze detection tube, an extension rod, and an air supply device, wherein the breeze detection tube is composed of a glass tube and a white smoke generating agent sealed in the glass tube, the extension rod is a hollow structure, one end of which is connected to the glass tube via a rubber joint, and the other end of which is connected to the air supply device, wherein the airflow generated by the air supply device enters the glass tube through the extension rod, so that the white smoke generated by the white smoke generating agent in the glass tube is blown out from the first opening end under the action of the airflow.

[0036] The detection tool for measuring the wind speed of the breeze in the tunnel provided by the present disclosure introduces an extension rod with adjustable length. By manually controlling the extension length of the extension rod and the airflow generated by the air supply device, the demand for accurate wind measurement by a single person is realized. The detection tool disclosed by the present disclosure not only saves manpower, but also overcomes the problem of inaccurate timing caused by two-person wind measurement, thereby improving the accuracy of measurement.

[0037] For ease of understanding, refer to Figures 1 to 5 , the specific structure and working principle of the detection tool for measuring the wind speed of the breeze in the tunnel disclosed in this invention are explained in detail with reference to an embodiment.

[0038] like Figure 1As shown, the present disclosure provides a detection tool for measuring the wind speed of a breeze in a tunnel, including a breeze detection tube 1, an extension rod 4 and an air supply device 16. The breeze detection tube 1 includes a glass tube 2 and a white smoke generator 3 sealed in the glass tube 2, and the white smoke generator 3 generates white smoke after contact with air; the opposite ends of the glass tube 2 are respectively marked as a first open end 21 and a second open end 22; the extension rod 4 is a hollow structure, one end of the extension rod 4 is connected to the glass tube 2 through a rubber joint 5, and is connected to the second open end 22 of the glass tube 2, and the other end is connected to the air supply device 16.

[0039] The airflow generated by the air supply device 16 enters the glass tube 2 through the extension rod 4 , so that the white smoke generated by the white smoke generating agent 3 in the glass tube 2 is blown out from the first open end 21 under the action of the airflow.

[0040] Specifically, existing anemometers in my country can measure wind speeds between 0.3 and 25 m / s. However, they have difficulty measuring breezes below 0.3 m / s. Therefore, to accurately measure wind speeds below 0.3 m / s, the present disclosure provides a detection tool for measuring breeze speed in tunnels, comprising a breeze detection tube 1, an extension rod 4, and an air supply device 16. The breeze detection tube 1 is the core component of the entire detection tool. It consists of a transparent glass tube 2 containing a specially prepared white smoke generator 3, which can be made of tin tetrachloride, titanium tetrachloride, or silicon tetrachloride. Upon contact with external air, the white smoke generator 3 reacts rapidly, producing a noticeable white smoke, thereby visually detecting changes in wind direction and speed.

[0041] Furthermore, to enhance the flexibility of the testing tool, it is equipped with a hollow extension rod 4. The glass tube 2 has two openings, defined as a first open end 21 and a second open end 22. One end of the extension rod 4 is connected to the second open end 22 of the breeze detection tube 1 via a tight rubber joint 5, ensuring a good seal and preventing external air from entering the breeze detection tube 1 and affecting the test results. The other end of the extension rod 4 is connected to an air supply device 16, which is responsible for delivering clean air into the breeze detection tube 1, promoting the full reaction of the white smoke generating agent 3 and producing clear white smoke.

[0042] During the actual detection process, the operator stands in the wind tunnel to be tested, holds up the extension rod 4 horizontally with both hands, and ensures that it remains parallel to the direction of the wind flow. The timer is started while the gas is introduced. After the white smoke flows out from the first opening end 21, it slowly moves along the direction of the extension rod 4 under the guidance of the breeze. When the edge of the white smoke reaches the port on the side of the extension rod 4 away from the breeze detection tube 1, the timing is stopped immediately. The horizontal distance from the port on the side of the extension rod 4 away from the breeze detection tube 1 to the breeze detection tube 1 is regarded as the predetermined length. By dividing this predetermined length by the recorded time, the wind speed in the current tunnel can be accurately calculated.

[0043] During use, the airflow generated by the air supply device 16 enters the breeze detection tube 1 from the second open end 22 via the extension rod 4, causing the white smoke generating agent 3 in the breeze detection tube 1 to react rapidly and produce white smoke. The generated white smoke is then blown out of the first open end 21 under the propulsion of the airflow. This sophisticated detection tool is adaptable to confined or complex underground environments, ensuring accurate and rapid acquisition of wind speed data. This is of great significance for wind speed detection in scenarios such as narrow tunnels.

[0044] like Figure 1 As shown, in one embodiment of the present disclosure, a plugging material 6 is provided in the glass tube 2 . The plugging material 6 is located at both ends of the white smoke generating agent 3 in the glass tube 2 , and the white smoke generating agent 3 is sealed in the glass tube 2 by the plugging material 6 .

[0045] To ensure the white smoke generating agent 3 is stably stored within the glass tube 2 and can effectively come into contact with air to generate white smoke when needed, special plugs 6 are placed inside the glass tube 2. These plugs 6 are made of a lightweight, harmless material, such as cotton. These plugs 6 are located at both ends of the white smoke generating agent 3. They not only secure the white smoke generating agent 3 to prevent it from leaking out of the glass tube 2 during use, but also provide good air permeability, allowing air to pass through and fully react with the white smoke generating agent 3. The breeze detection tube 1 is reusable. After each use, when no white smoke is generated in the glass tube 2, the first open end 21 can be covered with a rubber cap.

[0046] like Figure 1 As shown, in one embodiment of the present disclosure, the extension rod 4 includes at least a first telescopic tube 7, a second telescopic tube 8 and a locking structure 15. The first telescopic tube 7 is sleeved outside the second telescopic tube 8. The locking structure 15 is fixedly connected to the first telescopic tube 7 and is used to lock the second telescopic tube 8 extended to a predetermined length.

[0047] Specifically, to further enhance the flexibility and portability of the tunnel breeze speed detection tool, the extension rod 4 utilizes an adjustable-length telescopic tube structure. This telescopic tube structure allows the extension rod 4 to be retracted into a shorter state when not in use, making it easier to carry and store. When in use, it can be adjusted to an appropriate length based on actual conditions to meet the needs of different measurement points. The telescopic structure is typically made of materials such as stainless steel and possesses sufficient strength and stability to support the weight of the entire measuring tool and maintain its horizontal position during use. The first telescopic tube 7 serves as an outer tube, and its inner diameter is slightly larger than the outer diameter of the second telescopic tube 8, ensuring that the second telescopic tube 8 can slide freely within it. The second telescopic tube 8 serves as an inner tube and can be extended and retracted along the axis of the first telescopic tube 7, thereby achieving length adjustment. When the extension rod 4 is at its longest, it is the sum of the lengths of the first telescopic tube 7 and the second telescopic tube 8. When the extension rod 4 is at its shortest, it is equal to the length of the first telescopic tube 7.

[0048] like Figure 1 As shown, in one embodiment of the present disclosure, a seal is provided between the end of the first telescopic tube 7 and the end of the second telescopic tube 8. When the second telescopic tube 8 is in an extended state relative to the first telescopic tube 7, the seal seals the gap between the first telescopic tube 7 and the second telescopic tube 8.

[0049] Specifically, in order to ensure the sealing of the tunnel breeze speed detection tool during use, a sealing member is provided between the end of the first telescopic tube 7 and the end of the second telescopic tube 8. The sealing member is a circular ring structure, and the second telescopic tube 8 can pass through the inner ring of the sealing member. The sealing member is located at the end of the first telescopic tube 7 on the side away from the air supply device 16 and will not separate from the first telescopic tube 7. A baffle for preventing the second telescopic tube 8 from falling off the first telescopic tube 7 is provided on the side of the second telescopic tube 8 close to the first telescopic tube 7. When the baffle contacts the sealing member, the extended length of the second telescopic tube 8 is the longest. When the second telescopic tube 8 moves axially in the first telescopic tube 7, the sealing member seals the gap between the first telescopic tube 7 and the second telescopic tube 8 to prevent the airflow generated by the air supply device 16 from flowing out of the gap between the first telescopic tube 7 and the second telescopic tube 8. The sealing member is usually made of a wear-resistant, elastic material with excellent sealing performance, such as silicone, rubber, etc.

[0050] like Figure 2-Figure 5 As shown, in one embodiment of the present disclosure, the locking structure 15 includes a sleeve 9 and a rotating wheel 10, and the sleeve 9 is provided with a thread 11 for installing the rotating wheel 10, and the rotating wheel 10 moves axially on the sleeve 9; the rotating wheel 10 is an eccentric wheel, having a first center 101 and a second center 102. When the locking structure 15 is relaxed, the geometric center of the rotating wheel 10 is the first center 101, and when the locking structure 15 is locked, the geometric center of the rotating wheel 10 rotates to the second center 102.

[0051] Specifically, in order to achieve reliable fixation of the extension rod 4 at any length, the locking structure 15 adopts a combination of a sleeve 9 and a rotating wheel 10, wherein the sleeve 9 is fixedly connected to the end of the first telescopic tube 7 away from the air supply device 16, and is sleeved outside the first telescopic tube 7. A thread 11 is provided on the outer wall of the sleeve 9 for installing the rotating wheel 10. The thread 11 on the outer wall of the sleeve 9 serves as an external thread and matches the internal thread provided on the inner side of the rotating wheel 10. The rotating wheel 10 can be controlled to move axially along the sleeve 9 by rotation. The rotating wheel 10 is an eccentric wheel, and its rotation center does not coincide with the axis. The axis is recorded as the first circle center 101. When the locking structure 15 is relaxed, as shown in FIG. Figure 4 As shown, the geometric center of the rotating wheel 10 is at the first center 101. At this time, the inner wall of the rotating wheel 10 does not contact the second telescopic tube 8. When the user rotates the rotating wheel 10, the rotating wheel 10 moves axially along the thread 11 of the sleeve 9 and gradually approaches the second telescopic tube 8. As the rotating wheel 10 continues to rotate, its geometric center rotates from the first center 101 to the second center 102. Figure 5 As shown, due to the eccentric design of the rotating wheel 10, this process causes a portion of the rotating wheel 10 to press tightly against the second telescopic tube 8. This pressing force secures the second telescopic tube 8 in its current position, preventing it from slipping or loosening during use. To retract the second telescopic tube 8, simply rotate the rotating wheel 10 in the opposite direction to its initial position to release the locking state. This locking structure 15 is not only easy to operate but also provides a strong locking force, ensuring the stability of the second telescopic tube 8 in the desired position.

[0052] like Figure 1 As shown, in one embodiment of the present disclosure, the total length of the extension rod 4 is 2m-4m.

[0053] Specifically, considering that the wind speed at the position to be measured is lower than 0.3m / s and the white smoke generated by the breeze detection tube 1 is easy to dissipate, the total length of the extension rod 4 is set to 2m-4m. If the length of the extension rod 4 is less than 2m, the operator's timing is too short, which is easy to cause errors. If the length of the extension rod 4 is greater than 4m, the white smoke is easy to dissipate, and it is difficult for the operator to determine the position of the white smoke, which is also easy to cause errors. Using 2m-4m as the detection length can improve the accuracy of the measurement.

[0054] like Figure 1 As shown, in one embodiment of the present disclosure, the second telescopic tube 8 has a pipe joint 12 on one side away from the first telescopic tube 7 , and the other end of the pipe joint 12 extends in a direction perpendicular to the extension rod 4 , and the pipe joint 12 is used to install the breeze detection tube 1 .

[0055] Specifically, the pipe joint 12 is installed on the side of the second telescopic tube 8 away from the first telescopic tube 7, and the other end extends in a direction perpendicular to the extension rod 4 to form an L-shaped structure. The pipe joint 12 is used to install the breeze detection tube 1. The breeze detection tube 1 is fixed to the pipe joint 12 through the rubber joint 5, so that the breeze detection tube 1 and the extension rod 4 are in a vertical position. The white smoke generated in the breeze detection tube 1 can move along the measured distance of the extension rod 4 to avoid errors.

[0056] like Figure 1 As shown, in one embodiment of the present disclosure, the diameter of the pipe joint 12 is smaller than the diameter of the breeze detection tube 1 , and the pipe joint 12 is partially inserted into the breeze detection tube 1 .

[0057] Specifically, to enhance the stability of the connection between the pipe joint 12 and the second open end 22 of the glass tube 2, the diameter of the pipe joint 12 is set to be smaller than that of the breeze detection tube 1, allowing the pipe joint 12 to be partially inserted into the breeze detection tube 1. To ensure a good seal, a rubber joint 5 is provided at the connection between the pipe joint 12 and the second open end 22 as a sealing component to prevent the ingress of external air. Furthermore, the diameter of the pipe joint 12 is also smaller than the inner diameter of the extension rod 4. This arrangement increases the velocity of the internal airflow entering the breeze detection tube 1, ensuring that white smoke flows out of the first open end 21 of the breeze detection tube 1 while the air supply device 16 generates airflow. This ensures the accuracy of timing and further improves the accuracy of detection.

[0058] like Figure 1 As shown, in one embodiment of the present disclosure, the breeze detection tube 1 is perpendicular to the extension rod 4 .

[0059] Specifically, since the pipe joint 12 is configured to be connected to the second telescopic tube 8 at one end and extend in a direction perpendicular to the extension rod 4 at the other end to form an L-shaped structure, when the breeze detection tube 1 is fixedly connected to the pipe joint 12 through the rubber joint 5, the breeze detection tube 1 is perpendicular to the extension rod 4. In this configuration, during the measurement process, the white smoke generated in the breeze detection tube 1 can move along the measured distance of the extension rod 4. If the direction of the breeze detection tube 1 is offset, the actual movement distance of the white smoke will be different from the predetermined distance of the extension rod 4, and the measurement result will produce an error.

[0060] like Figure 1 As shown, in one embodiment of the present disclosure, the air supply device 16 includes a balloon 13 and a rubber tube 14, one end of the rubber tube 14 is sleeved on the first telescopic tube 7, and the other end of the rubber tube 14 is connected to the balloon 13. The air supply device 16 introduces air into the breeze detection tube 1 by squeezing the balloon 13.

[0061] Specifically, the balloon 13 is used to store and provide air. One end of the rubber tube 14 is sleeved on the first telescopic tube 7, and the other end is connected to the balloon 13. By squeezing the balloon 13, the air enters the first telescopic tube 7 through the rubber tube 14, and then passes through the second telescopic tube 8 and the pipe joint 12, and finally enters the interior of the breeze detection tube 1, prompting the white smoke generating agent 3 to produce white smoke. The air supply device 16 is small in size, easy to carry and store, and simple and quick to operate. If the rubber tube 14 or the balloon 13 is damaged, it can be easily replaced, and the maintenance cost is low.

[0062] During the specific detection process, an operator stands in the wind tunnel to be tested, holds the extension rod 4 horizontally with both hands so that the extension rod 4 is parallel to the wind direction, presses the balloon 13 and starts timing. White smoke then flows out from the first opening end 21 and moves along the extension direction of the extension rod 4 under the action of the breeze. The timing is stopped when the edge of the white smoke reaches the port of the extension rod 4 on the side away from the breeze detection tube 1. The horizontal distance from the port of the extension rod 4 on the side away from the breeze detection tube 1 to the breeze detection tube 1 is regarded as a predetermined length. The predetermined length is divided by the recorded time to calculate the tunnel wind speed at this time.

[0063] The detection tool for measuring the wind speed of the breeze in the tunnel provided by the present disclosure introduces an extension rod 4 with adjustable length. By manually controlling the extension length of the extension rod 4 and the airflow generated by the air supply device 16, the demand for accurate wind measurement by a single person is achieved. The detection tool disclosed by the present disclosure not only saves manpower, but also overcomes the problem of inaccurate timing caused by two-person wind measurement, thereby improving the accuracy of measurement.
