[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] Reference Figure 1-Figure 3 The utility model provides a button-type grating sensor intelligent support, comprising:

[0026] Support 2, two ends of the support 2 are respectively provided with connecting plates 1, two sets of connecting plates 1 are provided with nesting grooves 4 on one side close to the support 2, two ends of the support 2 are respectively inserted into the two sets of nesting grooves 4, and the two sets of connecting plates 1 are respectively fixedly connected to the beam body and the pier on one side away from the support 2;

[0027] A plurality of button-type grating sensors 3 are provided with a plurality of mounting grooves 6 on one side of the connecting plate 1 close to the support 2. The plurality of button-type grating sensors 3 are respectively plugged into the plurality of mounting grooves 6. The support 2 and the plurality of button-type grating sensors 3 are arranged correspondingly, and the plurality of button-type grating sensors 3 are electrically connected to each other.

[0028] The main function of the connecting plate 1 is to fix the button-type grating sensor 3 through the mounting groove 6, and to connect the support 2 between the two connecting plates 1 through the nesting groove 4; the main function of the support 2 is to support and buffer the beam of the bridge; the main function of the button-type grating sensor 3 is to measure the longitudinal load force borne by the support 2, and at the same time, the button-type grating sensors 3 on the two groups of connecting plates 1 can sense each other, and the risk of escape can be determined by measuring the relative displacement between the two groups of connecting plates 1; the connecting plate 1, the support 2 and the button-type grating sensor 3 are all detachably connected, and there is no one-piece molding structure, so a button-type grating sensor 3 can be quickly replaced. On the whole, the support and the connecting plate, as well as the connecting plate and the button-type grating sensor of the utility model are not integrally formed. Therefore, when replacing the sensor, there is no need to replace the entire support. Only one side of the button-type grating sensor needs to be disassembled. The operation is easy, the replacement effect is higher, and the replacement cost is low. At the same time, the button-type grating sensors on the two groups of connecting plates sense each other, and the displacement caused by the force is measured while measuring the force, so the detection information is more comprehensive.

[0029] Further optimization scheme, the button-type grating sensor 3 is a sensor based on the fiber Bragg grating principle. This type of sensor basically uses strain or temperature to change the grating center wavelength directly or indirectly to achieve the purpose of testing the measured physical quantity. Based on this, the button-type grating sensors 3 on the two sets of connecting plates 1 can measure the load force and detect the displacement between the two connecting plates 1 through mutual induction.

[0030] According to a further optimized solution, the outer contour of the support 2 is matched with the inner side of the nesting groove 4 , and the nesting groove 4 is used to limit the connection of the support 2 to the connecting plate 1 .

[0031] like Figure 1 and Figure 2 As shown, the support 2 and the nesting groove 4 are both designed to be circular. The main function of the nesting groove 4 is to connect the connecting plate 1 with one end of the support 2 so that a lateral limit is formed between the connecting plate 1 and the support 2 along the end surface of the connecting plate 1.

[0032] According to a further optimized solution, the mounting groove 6 is provided at the bottom of the nesting groove 4 , the inner diameter of the mounting groove 6 is matched with the outer diameter of the button-type grating sensor 3 , and the mounting groove 6 is used to install the button-type grating sensor 3 .

[0033] like Figure 2 As shown, the main function of the mounting groove 6 is to fix the button-type grating sensor 3 on the connecting plate 1. When the button-type grating sensor 3 needs to be removed, it only needs to be pulled out from the mounting groove 6.

[0034] A further optimization scheme is that an annular lead groove 5 and a cross lead groove 8 are opened at the bottom of the nesting groove 4, the central intersection of the cross lead groove 8 coincides with the center of the annular lead groove 5, the annular lead groove 5 and the cross lead groove 8 are connected at the intersection, an installation groove 6 is arranged at the central intersection of the cross lead groove 8, and the remaining installation grooves 6 are arranged on the annular lead groove 5 at equal intervals.

[0035] like Figure 2 As shown, in this embodiment, the mounting groove 6 on the annular lead groove 5 is arranged at the intersection of the annular lead groove 5 and the cross-shaped lead groove 8, plus the mounting groove 6 at the center of the annular lead groove 5, a total of five groups are arranged, that is, a total of five groups of button-type grating sensors 3 can be installed on the connecting plate 1.

[0036] According to a further optimization scheme, a plurality of button-type grating sensors 3 are connected in series via optical fiber conductors 7 , and the optical fiber conductors 7 are arranged in the annular lead groove 5 and the cross lead groove 8 .

[0037] like Figure 2 As shown, the main function of the annular lead groove 5 and the cross lead groove 8 is to accommodate the optical fiber wire 7 to prevent the optical fiber wire 7 from directly contacting the support 2 and the connecting plate 1, thereby preventing the optical fiber wire 7 from being damaged under the longitudinal load between the connecting plate 1 and the support 2.

[0038] According to a further optimized solution, the depth of the mounting groove 6 is two-thirds of the height of the button-type grating sensor 3 .

[0039] To further optimize the solution, the support 2 is made of rubber material.

[0040] The working process of this embodiment is as follows:

[0041] A plurality of button-type grating sensors 3 are respectively inserted into a plurality of mounting grooves 6 on two groups of connecting plates 1, and the button-type grating sensors 3 in the connecting plates 1 are electrically connected to each other. Specifically, five groups of button-type grating sensors 3 are respectively installed in five groups of mounting grooves 6, and the button-type grating sensors 3 are connected in series through optical fiber wires 7, and the optical fiber wires 7 are fixed in the annular lead groove 5 and the cross lead groove 8;

[0042] The two sets of connecting plates 1 are fixedly connected to the bottom of the beam body and the top of the corresponding bridge pier respectively;

[0043] Connect the support 2 to the connection plate 1 at the top of the pier, lower the beam body, connect the connection plate 1 at the bottom of the beam body to the top of the support 2, and complete the installation. Specifically, place the support 2 in the nesting groove 4 on the connection plate 1 at the top of the pier, then lower the beam body, nest the nesting groove 4 on the connection plate 1 at the bottom of the beam body in the top of the support 2, and complete the installation of the support;

[0044] When the button-type grating sensor 3 needs to be replaced, the beam body is lifted to separate the support 2 and the connecting plate 1, and the button-type grating sensor 3 can be replaced. Specifically, when the button-type grating sensor 3 needs to be replaced, it is only necessary to lift the beam body to separate the connecting plate 1 at the bottom of the beam body from the top of the support 2. At this time, the support 2 can be removed from the connecting plate 1 on the pier. At this time, there is sufficient operating space between the two sets of connecting plates 1, which is convenient for construction personnel to replace the button-type grating sensor 3.
