The change or adjustment of their relative relationship, without substantial change in the technical content, should also be regarded as the scope of the implementation of this utility model. The following embodiments are only for illustration. The various embodiments can be combined, which is not limited to the contents shown in the following single embodiments.

[0023] In one embodiment, see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the layout of the photoelectric bridge substructure scour monitoring device provided by the embodiment of the utility model. Figure 2 This is a schematic structural diagram of a photoelectric bridge substructure scour monitoring device provided in an embodiment of the utility model.

[0024] like Figure 1 and Figure 2 As shown, the bridge substructure includes a bridge foundation A1 and a bridge pier A2. The photoelectric bridge substructure scour monitoring device is arranged in the soft soil layer B2 around the bridge substructure. There is a water layer above the soft soil layer and a riverbed bearing layer B1 below the soft soil layer.

[0025] In this embodiment, the photoelectric bridge substructure scour monitoring device specifically includes a transmitting module 1, a receiving module 3 and a data module 6. The transmitting module 1 is arranged in the soft soil layer B2 around the bridge substructure, and the transmitting module 1 is used to transmit optical signals; the receiving module 3 is arranged in the soft soil layer B2 at the same level as the transmitting module 1 relative to the bottom surface of the bridge foundation A1 in the bridge substructure, and the receiving module 3 is used to receive the optical signal and convert the optical signal into an electrical signal; the data module 6 is connected to the receiving module 3 by signal, and the data module 6 is used to receive the electrical signal and generate the bridge substructure scour depth data according to the electrical signal.

[0026] Furthermore, the photoelectric bridge substructure scour monitoring device provided in this embodiment also includes a first support module 2 and a second support module 4. The first support module 2 is fixedly connected to the transmitting module 1, and the first support module 2 is vertically inserted into the soft soil layer B2. One end of the first support module 2 is located at the interface between the water layer and the soft soil layer B2, and the other end of the first support module 2 is located at the interface between the soft soil layer B2 and the riverbed bearing layer B1. The second support module 4 is fixedly connected to the receiving module 3, and the second support module 4 is vertically inserted into the soft soil layer B2. One end of the second support module 4 is located at the interface between the water layer and the soft soil layer B2, and the other end of the second support module 4 is located at the interface between the soft soil layer B2 and the riverbed bearing layer B1.

[0027] Furthermore, the signal connection between the data module 6 and the transmitting module 1 and the receiving module 3 can also be realized by wired connection through a wire, or by wireless connection using a signal transmission device such as a signal transmitter / signal receiver.

[0028] As the water flow scours the bridge substructure, it gradually carries away the silt in the soft soil layer B2 around the bridge substructure, and the thickness of the silt burying the transmitting module 1 and the receiving module 3 gradually decreases. When the silt between the transmitting module 1 and the receiving module 3 is scoured and hollowed out, the optical signal emitted by the transmitting module 1 is received by the receiving module 3, and the receiving module 3 converts the optical signal into an electrical signal and transmits it to the data module 6. The data module 6 learns from the source of the electrical signal that the scouring depth of the bridge substructure has at least reached the height of the transmitting module 1 and the receiving module 3.

[0029] In one or more other embodiments, the transmitting module 1 in the photoelectric bridge substructure scour monitoring device includes a plurality of transmitting sub-modules 11, and the plurality of transmitting sub-modules 11 are fixed on the surface of the first supporting module 2 in an equidistant or unequally spaced manner along the axial direction of the first supporting module 2.

[0030] like Figure 2 and Figure 3As shown, Figure 3 This is a structural schematic diagram of a transmitting module 1 and a receiving module 3 provided in an embodiment of the utility model. The transmitting module 1 includes four transmitting sub-modules 11. The four transmitting sub-modules 11 are fixed to the surface of the first supporting module 2 by first bolts 12 in an equidistant manner along the axial direction of the first supporting module 2.

[0031] Specifically, any transmitting submodule 11 is a single-point laser transmitter; the single-point laser transmitter has a stainless steel waterproof sheath, and the protection level of the stainless steel waterproof sheath is IPX6; the surface of the stainless steel waterproof sheath is coated with antifouling paint for ships.

[0032] Furthermore, the receiving module 3 in the photoelectric bridge substructure scour monitoring device also includes a plurality of receiving sub-modules 31, and the plurality of receiving sub-modules 31 are fixed on the surface of the second supporting module 4 in an equidistant or unequally spaced manner along the axial direction of the second supporting module 4.

[0033] like Figure 2 and Figure 3 As shown, the receiving module 3 includes four receiving sub-modules 31 , and the four receiving sub-modules 31 are fixed to the surface of the second supporting module 4 by second bolts 32 in an equidistant manner along the axial direction of the second supporting module 4 .

[0034] Specifically, any receiving submodule 31 is a photoresistor sensor; the photoresistor sensor has a stainless steel waterproof sheath, and the protection level of the stainless steel waterproof sheath is IPX6; the surface of the stainless steel waterproof sheath is coated with antifouling paint for ships.

[0035] In this or these embodiments, any transmitting submodule 11 is arranged relative to a receiving submodule 31 in a soft soil layer B2 at the same horizontal height relative to the bottom surface of the bridge foundation A1 in the bridge substructure to ensure that the optical signal emitted by the transmitting submodule 11 can be received by the corresponding receiving submodule 31.

[0036] In one or more other embodiments, the photoelectric bridge substructure scour monitoring device also includes a connection module 5, which is used to connect the first support module 2 and the second support module 4 to ensure the relative stability between the first support module 2 and the second support module 4.

[0037] like Figure 1 and Figure 2 As shown, the first support module 2 and the second support module 4 are inserted into the soft soil layer B2 in parallel, and one end of the first support module 2 away from the soft soil layer B2 is fixedly connected to the other end of the second support module 4 away from the soft soil layer B2 through the connecting module 5.

[0038] Furthermore, in order to protect the transmitting module 1 fixed on the first supporting module 2 and the transmitting module 1 fixed on the second supporting module 4, a plurality of axially distributed bevel blocks 7 are provided at the ends of the first supporting module 2 and the second supporting module 4 away from the connecting module 5.

[0039] Specifically, the first support module 2, the second support module 4 and the connection module 5 are all stainless steel brackets, and the first support module 2 and the second support module 4 are fixedly connected via the connection module 5 to form a "gate-type" stainless steel support structure to ensure the stability of the monitoring performance of the photoelectric bridge substructure scour monitoring device during the flood season.

[0040] In this embodiment, the power lines and signal lines of the transmitting module 1 and the receiving module 3 are all led out through the interior of the "gate-type" stainless steel support structure, buried in the wire trough on the surface of the bridge substructure to be tested, and upwardly merged into the data module 6 away from the water layer. It should be noted that all the led-out lines must be embedded in the surface of the bridge substructure through the wire trough, and must not be attached to the surface of the "gate-type" stainless steel support structure or the bridge substructure to prevent being washed away by floods during the flood season.

[0041] In this embodiment, multiple groups of 45° bevel blocks 7 are welded from bottom to top on the opposite side walls of the two legs of the "gate-type" stainless steel support structure. The bevel blocks 7 are stainless steel bevel blocks 7 to ensure that the "gate-type" stainless steel support structure is smoothly lowered into the soft soil layer B2, while protecting the transmitting module 1 and the receiving module 3 from damage during the lowering process of the "gate-type" stainless steel support structure.

[0042] In the actual installation process, if Figure 1 As shown, it is necessary to measure the thickness of the soft soil layer B2 at the installation location in advance, and then vertically insert the "gate-type" stainless steel support structure into the corresponding soft soil layer B2 until it reaches the interface between the soft soil layer B2 and the riverbed bearing layer B1, and reserve at least 1 / 3 of the length of the "gate-type" stainless steel support structure at the interface between the water layer and the soft soil layer B2 to facilitate the subsequent inspection and maintenance of the photoelectric bridge substructure scour monitoring device.

Among them, the external solar photovoltaic panels and small wind turbine generators can charge the batteries, and then provide power to the photovoltaic bridge substructure scour monitoring device through the batteries; when the battery is exhausted and the photovoltaic panels and wind turbine generators cannot supply power due to weather reasons, the backup batteries are used to supply power.

[0045] In one or more other embodiments, the photoelectric bridge substructure scour monitoring device also includes a protection module 8, which is arranged on the side of the first support module 2 and the second support module 4 away from the bridge substructure, and the protection module 8 is used to protect the transmitting module 1 and the receiving module 3.

[0046] like Figure 1 and Figure 4 As shown, Figure 4 The schematic diagram of the layout of the protection module 8 provided in the embodiment of the utility model is a protective net, and the protection module 8 is arranged on the side of the first support module 2 and the second support module 4 away from the bridge substructure.

[0047] In one or more other embodiments, the photoelectric bridge substructure scour monitoring device also includes an early warning module, which is signal-connected to the data module 6, and is used to generate an early warning signal based on the bridge substructure scour depth data, and perform corresponding early warning actions based on the early warning signal.

[0048] Furthermore, the early warning module specifically includes a light-emitting device, which is connected to the early warning module signal, and is used to perform a corresponding early warning action according to the early warning signal. Specifically, the light-emitting device is an LED light, and the number and color of the LED lights can be set according to actual needs. For example, when the risk level of the bridge substructure is low risk, the light-emitting device emits a green signal light; when the risk level of the bridge substructure is medium risk, the light-emitting device emits an orange signal light; when the risk level of the bridge substructure is high risk, the light-emitting device emits a red signal light.

[0049] Furthermore, the warning module specifically includes a sound-generating device, which is connected to the warning module signal and is used to perform a corresponding warning action according to the warning signal. Specifically, the sound-generating device is a sonar, and can emit warning sounds of different frequencies and volumes according to the risk level of the bridge substructure.

[0050] Furthermore, the early warning module specifically includes a communication device, which is used to send an early warning signal to a remote monitoring center. For example, through GPRS, 4G, 5G and other communication methods, the early warning signal is transmitted to the mobile phones, computers and other devices of relevant management agencies or staff to achieve timely response and processing.
