It should be noted that the force measuring unit 2 described in this embodiment is only an example, and any commercially available force measuring sensor that can collect a stress signal may be used in the implementation.
Example 2: an embodiment of the present invention provides a method for detecting a tensile flow rate and a flow direction, which is based on the tensile flow rate and flow direction detecting device described in embodiment 1, as shown in fig. 3, and includes:
step S201, collecting first force signals corresponding to the rotating plate under different angles through the force measuring unit, wherein the vertical direction of the position of the rotating plate corresponding to the maximum first force signal is the water flow direction.
The specific way of adjusting the angle of the rotating plate can be to manually adjust the rotating shaft or adjust the rotating plate by using a motor so as to enable the rotating plate to be at different angles. In particular, a processor may be provided to receive the first force signal of the force measuring unit, and to record the corresponding angle simultaneously when the corresponding first force signal is acquired, so that the vertical direction of the position of the rotating plate corresponding to the maximum first force signal can be directly calculated as the water flow direction.
When the water flow direction is perpendicular to the rotating plate, the force applied to the rotating plate is maximum, so that the first force signal collected by the force measuring unit is maximum, and the perpendicular direction of the position of the rotating plate corresponding to the maximum first force signal is taken as the water flow direction.
For a specific determination of the direction, the angle of rotation of the rotary plate can be adjusted by means of a motor, for example, on the basis of the initial position of the rotary plateθAnd record the first force signal F at the corresponding rotation angle 1 The angle between the vertical direction of the rotation plate and the initial position of the rotation plate can be defined as pi/2-θ+2kPi, wherekIs a natural number.

In some embodiments, the second force signal is a tension signal when the rotational speed of the track is less than the water flow speed.
The test is illustratively carried out in running water of known water flow speed, which is 1m/s, based on the procedure described above, in which the rotation direction of the track is made to coincide with the water flow direction, i.e. the direction of movement of the rotating plate moving over the track remains the same as the water flow direction when the track is turned around. The experimental results are shown in table 1.
TABLE 1 Water flow Rate test experiment data
As shown in table 1, the positive and negative values of the second force signal represent the tension signal and the compression signal, respectively, that is, represent the stress direction of the rotating plate. The caterpillar band is enabled to work for a period of time under the same rotating speed, as the rotating plate is in rotary motion, two stable pressure signals are measured, namely, two stable force signals acquired in the process of the rotating plate in linear motion are taken as second force signals, in other states, such as force signals in the rotating process of the rotating plate, the time of the whole rotary motion is shorter, and the force signals in the process have no meaning on the detection of the flow velocity, so that the force signals in the process are not adopted. The second force signal on the left side below the corresponding rotational speed in table 1 is the value of the second force signal collected by the force measuring unit in forward flow, and the second force signal on the right side is the value of the second force signal collected by the force measuring unit in reverse flow.
According to the table 1, when the rotation speed of the track is consistent with the water flow speed, the rotation plate is consistent with the water flow speed for a certain period of time, namely, is relatively static, and is not affected by the water flow pressure at the moment, so that when the rotation plate is not stressed, the second force signal is 0, the water flow speed can be determined according to the rotation speed of the track, and the detection of the water flow speed is realized.
Example 3: the embodiment of the invention provides a tensile flow velocity and flow direction detection method, which is based on the tensile flow velocity and flow direction detection device described in embodiment 1, as shown in fig. 4, and comprises the following steps:
step S301, collecting first force signals corresponding to the rotating plate under different angles by the force measuring unit, wherein the vertical direction of the position of the rotating plate corresponding to the maximum first force signal is the water flow direction.
In this step, the specific manner of adjusting the angle of the rotating plate may be to manually adjust the rotating shaft, or to adjust the rotating plate by using a motor, so that the rotating plate is at different angles. In the specific embodiment, a processor can be further configured to receive the first force signal of the force measuring unit, and record the corresponding angle simultaneously when the corresponding first force signal is acquired, so that the vertical direction of the position of the rotating plate corresponding to the maximum first force signal can be directly calculated as the water flow direction.
In step S302, the direction of the crawler belt is adjusted to be consistent with the water flow direction, so that the moving direction of the rotating plate and the water flow direction are on the same straight line when the crawler belt rotates.
Step S303, enabling the crawler belt to rotate at a first rotation speed, enabling the force measuring unit and the rotating plate to rotate along with the crawler belt, and collecting a second force signal through the force measuring unit.
After performing step S303, steps S304 and S305 are performed according to the properties of the force signal detected by the force measuring unit, including the tension signal and the pressure signal. When the rotating speed of the crawler belt is larger than the water flow speed, the second force signal is a pressure signal, and when the rotating speed of the crawler belt is smaller than the water flow speed, the second force signal is a tension signal.
Step S304, if the second force signal is a pressure signal, the first rotation speed is gradually reduced until the second force signal is 0, and the current first rotation speed is the water flow speed.
In some embodiments, if the second force signal is a pressure signal, the first rotational speed is gradually reduced according to a preset first value.
In step S305, if the second force signal is a tension signal, the first rotation speed is gradually increased until the second force signal is 0, and the current first rotation speed is the water flow speed.
In some embodiments, if the second force signal is a tension signal, the first rotational speed is gradually increased according to a preset first value.
Illustratively, the test was performed in running water of known water flow rate, the water flow rate of the running water being 1m/s, based on the procedure described above, and experimental tests were performed. In this experimental test, the track was rotated at a random rotational speed. For example, the first rotational speed of 0.5m/s is used for a period of time, the value of the second force signal collected at this time is 10.4N and-30.3N, the value of the second force signal collected by the force measuring unit when the rotating plate moves in the reverse direction is generally considered as the value of the second force signal collected by the force measuring unit, the value of the second force signal with smaller absolute value is used as the second force signal, i.e. the second force signal is the pulling force signal at this time, the first rotational speed is gradually increased, the first rotational speed is increased gradually according to a preset first value, wherein the preset first value is preset, and is determined according to the accuracy of the water flow speed to be measured, for example, when the water flow speed is 1m/s, the first value can be set to 0.1, 0.05, 0.01 and the like, and the embodiment is not particularly limited herein. Taking the first value of 0.1m/s as an example, the first rotating speed is gradually increased, when the first rotating speed is increased to 0.8m/s, the value of the second force signal is 4.3N, when the first rotating speed is increased to 1.0m/s, the value of the second force signal is 0N, and the current first rotating speed of 1.0m/s is determined to be the water flow speed.
Similarly, when the first rotational speed of the track for starting is greater than the water flow speed, for example, the first rotational speed is 1.5, the value of the collected second force signal is-10N and-50.2N, the absolute value of the second force signal is smaller, that is, -10N, the second force signal is the pressure signal, the first rotational speed is greater than the water flow speed, at this time, the first rotational speed can be reduced according to a preset first value, and similarly, the preset first value is determined according to the accuracy of the water flow speed to be detected. Taking the first value of 0.05m/s as an example, the first rotating speed is gradually increased, when the first rotating speed is reduced to 0.8m/s, the value of the second force signal is-4.0N, when the second rotating speed is reduced to 1.0m/s, the value of the second force signal is 0N, and the current first rotating speed of 1.0m/s is determined to be the water flow speed.
The above embodiments are only for illustrating the present invention, not for limiting the present invention, and various changes and modifications may be made by one of ordinary skill in the relevant art without departing from the spirit and scope of the present invention, and therefore, all equivalent technical solutions are also within the scope of the present invention, and the scope of the present invention is defined by the claims.
