Description

Technical Field

[0001] The present invention relates to the technical field of flood control facility operation management, and in particular to a dynamic sensing system and method for a flood control gate. Background Art

[0002] Levees are an important part of the flood control engineering system and are of great significance for protecting people’s lives and property and industrial and agricultural production.

[0003] A large number of flood control gates are set up in traditional embankment projects. There are three main types of flood control gates: tidal flap gates, flood control gates and tidal gates. The door axis of the tidal flap gate is usually parallel to the horizontal plane, and the tidal flap gate has a certain angle with the horizontal plane. The tidal flap gate can be opened and closed by rotating around the axis of its door axis. The door axis of the flood control gate is usually perpendicular to the horizontal plane. The flood control gate can be opened and closed by rotating around the axis of its door axis. The tidal gate can be opened and closed by lifting and lowering movement in the vertical direction. Among them, the tidal flap gate is mainly set in a small-diameter through-embankment culvert for one-way water blocking. When the water level of the river channel is lower than the water level in the embankment, the tidal flap gate will automatically open after being pressurized by the water in the embankment, and the through-embankment culvert can discharge water into the river. When the water level of the river channel is higher than When the water level inside the dike is high, the tidal gates will automatically close under the pressure of the river water and their own gravity, which can prevent the backflow of river water. The tidal gates are mainly used to meet the needs of tide blocking and drainage, preventing the backflow of high water bodies and ensuring urban flood control safety; flood control gates are mainly set on flood control walls to meet the functional requirements of daily maintenance of flood control walls, flood prevention and rescue, transportation logistics and terminal transportation; tidal gates are mainly set in large-diameter culverts through the dike for two-way water blocking. During high tide, the tide level is higher than the inland river level. Closing the tidal gates can prevent the tide from backflowing into the river. During low tide, the tide level is lower than the inland river level. Opening the tidal gates can discharge flood water, drain water and flush silt. The tidal gates are mainly used to meet the requirements of reducing the tidal inflow and siltation in the river.

[0004] During floods and high tides, the levees need to withstand huge water pressure. In order to ensure their stability and safety, in addition to regular maintenance and reinforcement of the levees, it is also necessary to strengthen the maintenance and management of a large number of flood control gates and eliminate potential hidden dangers in a timely manner. However, for a long time, the maintenance and management of flood control gates mainly adopts a combination of regular maintenance and passive maintenance. Among them, regular maintenance refers to regular maintenance of all flood control gates after each period of use, and passive maintenance refers to the repair of damaged flood control gates after they are damaged, that is, they cannot be opened or closed. The traditional maintenance and management methods of flood control gates, on the one hand, there is a situation of excessive maintenance, which will greatly waste manpower, material and financial resources. On the other hand, the timeliness of maintenance is poor, and maintenance is usually carried out after the flood control gates cannot be used, which has potential risks. At the same time, the traditional method also needs to rely on a large number of manpower, which is not only time-consuming and labor-intensive, but also has a huge workload.

[0039] See also Figures 1 to 7 The present invention provides a flood control gate dynamic sensing system for sensing the opening and closing status of the flood control gate. The flood control gate dynamic sensing system includes a flood control gate dynamic sensing device 1, a data acquisition and transmission device 2, a remote management platform 3 and a communication network; the flood control gate dynamic sensing device 1 can measure the opening and closing status data of different types of flood control gates, and transmit it to the remote management platform 3 through the data acquisition and transmission device 2 and the communication network; the data acquisition and transmission device 2 can set the parameters of the flood control gate dynamic sensing device 1, and the data acquisition and transmission device 2 can collect the opening and closing status data of the flood control gate dynamic sensing device 1, and transmit the opening and closing status data to the remote management platform 3 through the communication network; the remote management platform 3 can receive, analyze and display the opening and closing status data transmitted by the data acquisition and transmission device 2 and the communication network, and judge the opening and closing status of different types of flood control gates.

[0040] The basic working principle of the flood control gate dynamic sensing system involved in the present invention is: the flood control gate dynamic sensing device 1 has a measuring component, which can measure the opening and closing status data of different types of flood control gates to provide a data basis, and the opening and closing status data can be transmitted to the remote management platform 3 through the data acquisition and transmission device 2 and the communication network.

[0041] See also Figures 2 to 7 The present invention is further described below with a specific embodiment:

[0042] In this embodiment, see Figures 2 to 7 As a preferred design, the flood control gate includes a tide flap gate, a flood control gate and a tide gate. The flood control gate dynamic sensing device 1 includes a tide flap gate sensing mechanism 5 for obtaining tide flap gate rotation data, a flood control gate sensing mechanism 6 for obtaining flood control gate rotation data, a tide gate sensing mechanism 7 for obtaining tide gate displacement data and a sensor cable 4 for connecting to the data acquisition and transmission device 2.

[0043] In this embodiment, see Figure 2 and Figure 3As a preferred design, the tide-beating door sensing mechanism 5 includes a tilt sensor 51 and a sealing assembly 52. ​​The sealing assembly 52 is fixedly connected to the tide-beating door. The tilt sensor 51 includes a ring potentiometer, a slider 511 and a gravity element 512. The slider 511 is hinged on the central axis of the ring potentiometer. The basic principle of the ring potentiometer for measuring the rotation angle is that the measuring resistance of the ring potentiometer is proportional to the rotation angle of the slider 511. Assuming that the total resistance of the ring potentiometer is R0, corresponding to a circular angle of 360°, and the measuring resistance is R1, the rotation angle ψ=R0 / 360×R1. When the annular potentiometer rotates relative to the slider 511, the resistance of the annular potentiometer changes, and the rotation angle of the tide-beating door is measured by the change in resistance. The annular potentiometer is fixedly mounted on the inner wall of the sealing assembly 52. ​​One end of the slider 511 is hinged at the center of the annular potentiometer, and a gravity element 512 is provided at the other end. Under the action of the gravity element 512, the slider 511 always remains perpendicular to the horizontal plane. When the tide-beating door rotates, the annular potentiometer rotates synchronously with the slider 511. The inclination sensor 51 may also adopt other existing structural designs.

[0044] In this embodiment, see Figure 3 As a preferred design, the sealing assembly 52 includes a first sealing box 521 and a second sealing box 522. The first sealing box 521 is located in the inner cavity of the second sealing box 522. Specifically, the second sealing box 522 can be fixed to the tide-beating door by bolts or can be directly welded to the tide-beating door. The inclination sensor 51 is arranged in the inner cavity of the first sealing box 521. The inner cavity of the first sealing box 521 is filled with damping oil. The damping oil can reduce the impact of the tide-beating door's own vibration on the inclination sensor 51, improve the accuracy of the inclination sensor 51, and make the data collected by the inclination sensor 51 relatively stable. The inner cavity of the second sealing box 522 is filled with silica gel, which can improve the oil leakage and water seepage prevention performance of the inclination sensor 51.

[0045] In this embodiment, see Figure 4 , Figure 5 and Figure 6As a preferred design, the flood control gate sensing mechanism 6 includes an angle sensor 61, a fixed bracket 62 and a connecting assembly 63.

The fixed measuring part of the angle sensor 61 is fixedly arranged on the fixed bracket 621, and the rotating shaft is rotatably connected to the end face of the fixed measuring part, and the rotating shaft is located at the center of the end face of the fixed measuring part. The fixed measuring part and the rotating shaft are both installed above the gate shaft of the flood control gate, and the fixed measuring part and the rotating shaft are both connected to the flood control gate. The rotation axis of the gate is coaxial, one end of the connecting component 63 is fixedly connected to the rotating shaft, and the other end is connected to the flood control gate, specifically, it can be connected to the convex seat of the flood control gate. The connecting component 63 and the flood control gate are fixed in the circumferential direction of the rotating shaft, and can move relative to each other in the radial direction. When the flood control gate rotates, the rotating shaft is driven to rotate synchronously through the connecting component 63. Among them, the fixed measuring part of the angle sensor 61 can also use a ring potentiometer and a slide 511 to measure the rotation angle of its rotating shaft. The slide 511 is fixed to the rotating shaft, and the rotating shaft is coaxial with the central axis of the ring potentiometer. The angle sensor 61 can also use other existing sensors. In other embodiments, the flood control gate sensing mechanism 6 can also adopt other existing structural designs.

[0046] In this embodiment, see Figure 5 and Figure 6 As a preferred design, the connecting component 63 is provided with an elongated hole extending radially along the rotating shaft. The connecting component 63 is connected to the flood control gate through a sliding nail. The sliding nail is fixedly connected to the flood control gate. The sliding nail is located in the elongated hole and has a clearance fit. The sliding nail can slide in the elongated hole. The elongated hole can prevent the flood control gate from radially squeezing the connecting component 63 and the rotating shaft, causing damage to the angle sensor 61.

[0047] In this embodiment, see Figure 7As a preferred design, the tide gate sensing mechanism 7 includes a displacement sensor 71, a bracket 72, a pulley 73, a pull rope 74 and a weight 75.

When the tide gate is lifted and lowered, the pulley 73 is driven to rotate. The displacement sensor 71 can detect the rotation angle of the pulley 73, and calculate the displacement data of the tide gate through the rotation angle of the pulley 73 and the circumference of the pulley 73. The lifting and displacement of the tide gate is carried out underwater. The tide gate sensing mechanism 7 can transfer the underwater displacement that is inconvenient to measure to the surface above the water for measurement, and at the same time convert the straight into the curved, which is convenient for implementation. The displacement sensor 71 includes a fixed part, a rotating shaft and a spiral potentiometer, wherein the fixed part is cylindrical, the rotating shaft is located at the center of the fixed part, the spiral potentiometer is arranged between the fixed part and the rotating shaft, and the slider of the spiral potentiometer rotates with the rotating shaft. By measuring the resistance change of the spiral potentiometer, the number of rotations of the rotating shaft relative to the fixed part is obtained. The displacement sensor 71 can also adopt other existing sensors. In other embodiments, the tide gate sensing mechanism 7 can also adopt other existing structural designs.
