Description

Technical Field

[0001] The invention relates to the field of moving bed model test monitoring, in particular to a device for monitoring the scouring test morphology of a vertical well for drainage and intake. Background Art

[0002] The drainage shaft is an important structure in civil engineering. For example, the urban drainage shaft is an important part of the urban flood control and drainage system. The drainage shaft is used as the drainage entrance of the system to collect and transport excess rainwater or flood water to prevent urban waterlogging. Whether it is a water conservancy project or a power project involving a shaft structure, the local scouring problem around the shaft is an important factor to be considered in the design and construction of the drainage shaft. Reasonable design and construction measures can effectively prevent the impact caused by scouring, which can not only save project investment, but also help ensure the safety of project construction and operation. At present, in the drainage shaft scouring test, the main methods for measuring the surface elevation change of the riverbed around the drainage shaft are: first, a number of vertical shaft walls are arranged around the drainage shaft and a representative section passing through the center of the shaft, and the cross-section terrain monitoring equipment is used for scouring monitoring. This method is more suitable for surface and large-scale scouring and silting monitoring, but it is not suitable for small-scale and small-scale monitoring of local scouring caused by structures. Since the monitoring section position needs to be repeatedly moved manually, the work efficiency is low. The second is a method of monitoring by placing a camera in the cavity of the structure. The structure is required to be made of transparent materials and be completely sealed. Scale lines are drawn on the inner side walls of the structure. The camera is placed in the simulated structure cavity, and then pictures are taken during the test to achieve scour monitoring. This method uses non-contact means, does not affect the water flow, and does not damage the terrain. However, for test objects similar to drainage shafts, it is also necessary to consider the impact of internal drainage on scour, and this method cannot be implemented. Existing public technologies include CN218298284U for measuring the flow rate of the riverbed, but there is still room for research on equipment for measuring the surface elevation of the riverbed. Summary of the invention

[0003] The purpose of the present invention is to provide a device for monitoring the morphology of drainage shaft scour tests. By setting an inductive probe, a four-way controller is connected to the inductive probe through a rotation controller of a base to achieve all-round displacement of the outside of the device. The inductive probe realizes vertical displacement above the riverbed through the four-way controller, and transmits the measurement signal back after contacting the surface of the riverbed, which is converted and obtained to obtain the bottom bed elevation of the measurement point. The present invention can accurately measure the surrounding terrain height of the drainage shaft.

[0004] The device used for monitoring the morphology of flushing tests in drainage shafts includes a base, which is connected to a rotary controller on the top, a connecting portion is provided on the top of the rotary controller, a vertical bracket base is provided on the top of the connecting portion, a vertical bracket is connected to the top of the vertical bracket base, a vertical bracket is connected to a bracket lifting device on the side of the vertical bracket, a horizontal bracket is fixed on the side of the bracket lifting device, a horizontal connecting rod is connected inside the horizontal bracket, a four-way controller is sleeved on the horizontal connecting rod, a vertical connecting hole is provided in the four-way controller, a probe connecting rod is provided in the vertical connecting hole, and an induction probe is provided at the end of the probe connecting rod.

[0005] The base is used to stabilize the entire scour monitoring device. The rotary controller rotates around its own central axis to realize the external horizontal movement detection of the probe connecting rod. The connecting part is used to connect the vertical bracket base and the rotary controller. The vertical bracket base is used to stabilize the upper mechanism. The bracket lifting device moves up and down in the vertical bracket to set a reference height for the entire detection device. The horizontal connecting rod inside the horizontal bracket is used to guide the horizontal movement of the four-way controller. The four-way controller is used to vertically connect the probe connecting rod and the horizontal connecting rod. The inductive probe at the end of the probe connecting rod realizes vertical displacement along the vertical connection hole, and transmits the electrical signal back after contacting the riverbed surface, which is converted and obtained to obtain the height distance between the measurement point and the reference height.

[0006] The rotary controller includes an external support, an internal bearing in the external support, and the internal bearing is connected to the connection part. When the bracket lifting device moves up and down, or the four-way controller moves in the horizontal direction, some vibration may be generated. At this time, the internal bearing has a vibration-absorbing effect and can stabilize the entire monitoring device.

[0007] The rotary controller is a disc-shaped structure with a diameter-to-thickness ratio of 8:1 to 9:1, and can rotate freely around its central axis, thereby driving the horizontal bracket to rotate around the vertical bracket, and further driving the probe connecting rod to move in the horizontal direction, ensuring that the probe connecting rod can detect the measuring point in the horizontal direction.

[0008] A motor is fixed above the top edge of the connection part, and the motor housing is a cube structure, and one side of the housing fits the vertical bracket base. The motor is connected to the rotation controller, the bracket lifting device, and the four-way controller to realize the overall power supply of the device.

[0009] The bracket lifting device is connected to the vertical bracket slide, and the bracket lifting device can move freely up and down along the vertical bracket. An initial height can be set by moving the vertical bracket, and the initial height is used as the reference height. Finally, the height distance measured by the inductive probe is obtained by calculating the difference between the inductive probe and the reference height.

[0010] A scale is provided above the horizontal support, and the end of the horizontal support is connected to the connecting rod fixing device. The scale can intuitively let the surveyor know the horizontal distance between the measured point and the shaft, and the connecting rod fixing device is used to fix the horizontal connecting rod.

[0011] The four-way controller is a rectangular structure with a horizontal connection hole inside to cooperate with the horizontal connecting rod. The four-way controller can move freely left and right on the horizontal connecting rod. The four-way controller and the rotation controller ensure the horizontal movement of the probe connecting rod, and can measure any point on the horizontal plane.

[0012] The outer periphery of the probe connecting rod column is matched with the vertical connection hole, and the probe connecting rod can move freely up and down in the vertical connection hole. In the drainage shaft scouring test, several linear measurement sections are usually arranged around the drainage shaft to monitor the surface elevation changes of the riverbed around the drainage shaft. The riverbed bottom is uneven, and the up and down movement of the probe connecting rod is to measure the height value of the riverbed surface. The height value of the probe connecting rod moving up and down will be recorded by the inductive probe at the end, and the difference with the reference height is calculated to obtain the riverbed surface height.

[0013] The advantages of the present invention are: through the combined movement of the rotary controller, the bracket lifting device and the four-way controller, the inductive probe can measure the elevation of any point of the riverbed beside the shaft. It overcomes the efficiency problem of the linear section monitoring method that requires frequent manual movement of the monitoring section, and overcomes the disadvantage that the camera photography monitoring method requires the structure to be sealed with transparent materials and cannot be implemented in the drainage scouring test.

[0020] The base 50 is used to stabilize the entire scour monitoring device. The rotation controller 51 rotates around its own central axis to realize the external horizontal movement detection of the probe connecting rod 20. The connecting part 52 is used to connect the vertical bracket base 53 and the rotation controller 51. The vertical bracket base 53 is used to stabilize the stability of the mechanism above it. The bracket lifting device 55 moves up and down in the vertical bracket 54 to set a reference height for the entire detection device. The horizontal connecting rod 41 inside the horizontal bracket 40 is used to guide the horizontal movement of the four-way controller 30. The four-way controller 30 is used to vertically connect the probe connecting rod 20 and the horizontal connecting rod 41. The inductive probe 10 at the end of the probe connecting rod 20 realizes vertical displacement along the vertical connection hole 32, and transmits the electrical signal back after contacting the surface of the riverbed, and converts and obtains the height distance between the measurement point and the reference height.

[0021] The rotation controller 51 includes an external support 510, and an internal bearing 511 is arranged inside the external support 510, and the internal bearing 511 is connected to the connection part 52. When the bracket lifting device 55 moves up and down, or the four-way controller 30 moves in the horizontal direction, some vibration may be generated. At this time, the internal bearing 511 has a vibration-absorbing effect, which can stabilize the entire monitoring device.

[0022] The rotation controller 51 is a disc-shaped structure, with a diameter-to-thickness ratio of 8:1 to 9:1, and can rotate freely around its central axis, thereby driving the horizontal bracket 40 to rotate around the vertical bracket 54, and further driving the probe connecting rod 20 to move in the horizontal direction, ensuring that the probe connecting rod 20 can detect measurement points in the horizontal direction.

[0023] A motor 60 is fixed above the top edge of the connecting portion 52, and the housing of the motor 60 is a cube structure, and one side of the housing fits the vertical bracket base 53. The motor 60 is connected to the rotation controller 51, the bracket lifting device 55, and the four-way controller 30 to realize the overall power supply of the device.

[0024] The bracket lifting device 55 is connected to the sliding groove of the vertical bracket 54, and the bracket lifting device 55 can move freely up and down along the vertical bracket 54. An initial height can be finally set by moving the vertical bracket 54, and the value of the initial height is used as the reference height. Finally, the height measured by the inductive probe 10 is determined by calculating the difference between the inductive probe 10 and the reference height.

[0025] A scale 43 is provided above the horizontal support 40, and the end of the horizontal support 40 is connected to a connecting rod fixing device 42. The scale 43 can intuitively let the surveyor know the horizontal distance between the measured point and the shaft, and the connecting rod fixing device 42 is used to fix the horizontal connecting rod 41.

[0026] The four-way controller 30 is a rectangular parallelepiped structure, and is provided with a horizontal connection hole and a horizontal connecting rod 41.

In the drainage shaft scouring test, a number of linear measurement sections are usually arranged around the drainage shaft to monitor the elevation change of the riverbed surface around the drainage shaft. The riverbed bottom is uneven, and the up and down movement of the probe connecting rod 20 is to measure the height value of the riverbed surface. The up and down movement height value of the probe connecting rod 20 will be recorded by the inductive probe 10 at the end, and the riverbed surface height is obtained by calculating the difference with the reference height.

[0028] Embodiment 2: See attached Figure 2 As shown, the inductive probe 10 is connected to the airbag 11. The wireless data transmission method between the inductive probe 10 and the external computer can refer to the public technology CN204539137U. The inductive probe 10 will transmit the measured value of the riverbed surface to the external computer during operation. The inductive probe 10 is moved during the measurement and placement process, and the height data obtained changes gradually. If the water flow impact is too large, the inductive probe 10 may be washed away, and the height data will suddenly change. When the computer detects this sudden change, it will send an alarm to remind the staff to pay attention and then remotely control the airbag 11 to inflate, and finally make the inductive probe 10 float on the water surface for the staff to recover and salvage. The specific method of inflating the airbag 11 can refer to the automobile safety airbag inflation method.
