Description

Technical Field

[0001] The utility model relates to the field of riverbed sediment depth measurement, and more specifically, to a riverbed sediment depth measurement device for hydrology. Background Art

[0002] The river has a high sand content and there is siltation in the river channel all year round. In water conservancy hubs, river bank dam protection, bridges and other projects, siltation in the river channel is quite common. Siltation is often caused by the reduction of the intensity of water flow erosion and siltation. The siltation in the river channel brings certain safety hazards to the area where the basin is located, and it is necessary to measure the silt depth in the river channel regularly.

[0003] Chinese patent CN118149772A discloses an intelligent measuring device for water conservancy projects, which belongs to the technical field of equipment for water conservancy project construction. The intelligent measuring device for water conservancy projects includes: a protective shell, a lifting rope is fixedly connected to the upper end of the protective shell, a mounting seat is installed in the protective shell, a camera is installed on the mounting seat, a sediment sensor is installed on one side of the camera, a protective cover is fixed on one side of the mounting seat, and a telescopic mechanism is installed in the protective shell. The technical solution of this application is provided with a protective shell, a mounting seat and a telescopic mechanism. The protective shell can protect the camera and the sediment sensor to prevent the sand and garbage in the river from damaging the measuring instrument. After reaching the specified depth, under the action of the telescopic mechanism, the mounting seat can drive the camera and the sediment sensor to extend out of the protective shell to measure the river, which can not only ensure the smooth measurement, but also greatly reduce the probability of damage to the measuring instrument.

[0004] However, in actual use, such as in the existing process of measuring the depth of riverbed sediment, regular testing is required, which requires repeated installation and measurement of the measuring equipment, greatly increasing the manpower and time consumed for each measurement. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides a riverbed sediment depth measuring device for hydrology, by installing a main platform at the measuring position, and inserting a measuring tube downward into the riverbed along the center of the main platform. As the river flows, sediment is deposited, and the sediment enters the measuring rod through the through groove. When it is necessary to know the sediment depth, the measuring tube can be pulled upward for observation. After the observation, it is inserted back into the riverbed to continue measuring and collecting the next data, thereby avoiding repeated measurement of equipment and greatly reducing the time and manpower consumed in measurement.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for measuring the depth of riverbed sediment for hydrology, comprising:

[0007] A main platform, wherein mounting rods are arranged at the four corners of the bottom end of the main platform, a connecting seat is fixedly installed on the top end of the mounting rods, and the top end of the connecting seat is fixedly connected to the main platform;

[0008] The measuring tube is inserted from the center of the main platform, an interlayer is provided inside the measuring tube, an inner tube is provided inside the interlayer, and through grooves are provided on the outer surfaces of the measuring tube and the inner tube.

[0009] Furthermore, a base is fixedly mounted on the bottom end of the mounting rod, and the interior of the mounting rod is a hollow structure, so that the main platform is supported by the mounting rod and the base.

[0010] Furthermore, a drill rod is inserted into the inner bottom end of the installation rod, a push rod is inserted into the inner top end of the installation rod, and the bottom end of the push rod is fixedly connected to the drill rod, and the drill rod is pushed into the soil layer by the push rod for fixation.

[0011] Furthermore, a rotating disk is rotatably provided at the top end of the measuring tube, and the top end of the inner tube is fixedly connected to the rotating disk, so that the inner tube is driven to rotate by rotating the rotating disk.

[0012] Furthermore, an observation window is fixedly installed on the outer surface of the inner tube, and a scale is provided on the outer surface of the observation window, so that the depth of the sediment can be observed through the observation window.

[0013] Technical effects and advantages of the utility model:

[0014] By installing the main platform at the measurement position, the measuring tube is inserted downward to the riverbed along the center of the main platform. As the river flows, sediment is deposited and enters the measuring rod through the through groove. When the sediment depth needs to be understood, the measuring tube can be pulled upward for observation. After the observation, it is inserted back into the riverbed to continue measuring and collecting the next data, thus avoiding repeated measurement of equipment and greatly reducing the time and manpower consumed in measurement.
