Detailed Description
Features and exemplary embodiments of various aspects of the utility model are described in detail below. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the utility model. It will be apparent, however, to one skilled in the art that the present utility model may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the utility model by showing examples of the utility model. The present utility model is in no way limited to any particular configuration and algorithm set forth below, but rather covers any modification, substitution, and improvement of elements, components, and algorithms without departing from the spirit of the utility model. In the drawings and the following description, well-known structures and techniques have not been shown in order to avoid unnecessarily obscuring the present utility model.
In industrial production, the actual storage capacity of a large storage bin is often measured by using a micro-strain sensor, the problem that relative movement between the sensor and a mounting base occurs often exists after long-time application, and in order to meet the production requirement, the sensor capable of accurately measuring the weight of materials in the storage bin is needed.
However, the existing micro-strain sensor has the problem that the sensor and the mounting base move relatively, the displacement between the sensor and the mounting base is not obvious at the initial stage of mounting the micro-strain sensor, but the displacement between the micro-strain sensor and the mounting base becomes obvious with the passage of time, so that the measurement of the micro-strain sensor is failed. And when the temperature of the surrounding environment changes, the elasticity coefficient of the storage bin support column also changes along with the temperature, and the existing micro-strain sensor cannot adjust the acquired data according to the temperature change, so that the measurement reality value is influenced when the temperature of the environment changes.
In order to overcome the defects of the prior art, the utility model provides an anti-displacement material level measuring device, and the anti-displacement material level measuring device provided by the embodiment of the utility model is described below with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of an anti-displacement level measuring device in an embodiment of the present utility model, as shown in fig. 1, the measuring device includes an upper mounting base 1, a lower mounting base 2, and a micro-strain sensor 3, wherein the upper mounting base 1 and the lower mounting base 2 are fixedly connected with the micro-strain sensor 3, and the micro-strain sensor 3 is provided with anti-slip teeth 4 on a contact surface with the upper mounting base 1 and the lower mounting base 2;
the upper mounting base 1 and the lower mounting base 2 are respectively fixed at the upper end and the lower end of the micro-strain sensor 3 and are used for being fixed on the surface of a measured object.
That is, the upper mounting base 1 and the lower mounting base 2 are fixed to the surface of the object to be measured, thereby enabling the micro strain sensor 3 to measure the object to be measured.
In some embodiments, the surface of the test object may be a storage bin pillar to enable detection of the level of the storage bin.
According to the utility model, the anti-slip teeth are arranged at the parts, which are contacted with the mounting base, of the upper end and the lower end of the micro-strain sensor, so that the friction force between the micro-strain sensor and the mounting base is increased by the anti-slip teeth to enable the micro-strain sensor and the mounting base to be tightly connected, and the displacement between the micro-strain sensor and the mounting base along with the time is avoided by a friction force increasing method, so that the measurement accuracy is reduced.

Therefore, the arc-shaped contact surface can be conveniently positioned when being welded to the round support, and the base formed by the arc-shaped contact surface can be firmly attached to the round support. When the change of the weight of the storage bin brings deformation to the round pillar, the deformation transmissibility of the mode is higher. The existing micro-strain sensor is not provided with an arc-shaped base, and the deformation transmissibility is higher due to the fact that the arc-shaped base is added, so that the measurement authenticity of the micro-strain sensor is further improved.
In some embodiments, fig. 3 is a schematic structural diagram of another anti-displacement level measurement device, as shown in fig. 3, the micro-strain sensor 3 includes a signal acquisition module and a temperature compensation module 7;
the temperature compensation module 7 is used for acquiring the ambient temperature and compensating the signal acquired by the signal acquisition module based on the ambient temperature.
That is, the micro-strain sensor comprises a signal acquisition module and a temperature compensation module, wherein the built-in temperature compensation module can sense the temperature of the surrounding environment, when the temperature of the surrounding environment changes, the elasticity coefficient of the storage bin support column also changes along with the temperature, the data acquired by the signal acquisition module is adjusted, and the built-in temperature compensation module is added, so that the measured value acquired by the micro-strain sensor is higher in precision and accuracy, and therefore, the measured value is more accurate when the temperature of the surrounding environment changes.
In some embodiments, as shown in connection with fig. 1 and 3, the upper mounting base 1 and the lower mounting base 2 may be fixedly connected to the micro-strain sensor 3 by bolts 8.
In some embodiments, the upper mounting base 1 and the lower mounting base 2 are respectively fixed at the upper end and the lower end of the micro-strain sensor, and can also be fixed on the surface of the tested object by using a welding mode.

And the arc-shaped base is added for the micro-strain sensor, so that the micro-strain sensor is convenient to position when welded to the circular support, the arc-shaped base is more firmly attached to the circular support, and when the circular support is deformed due to the change of the weight of the storage bin, the deformation transmissibility of the mode is higher, so that the measurement authenticity of the micro-strain sensor is improved
Furthermore, a built-in temperature compensation module is added for the micro-strain sensor, and when the influence of the ambient temperature on the measured value is brought, the built-in temperature compensation module can correct the micro-strain sensor in real time according to the ambient temperature change, so that the measurement accuracy of the micro-strain sensor is improved.
Compared with the prior art, the utility model can successfully offset the displacement between the micro-strain sensor and the mounting base, effectively cope with the displacement and improve the measurement precision of the micro-strain sensor.
