[0001] This utility model relates to the field of river hydrological surveying technology, and in particular to a river hydrological surveying device. Background Technology

[0002] River hydrological mapping equipment is a technical tool for monitoring core parameters such as river water level, flow velocity, and flow rate. Its application spans the entire process of water resource allocation, flood control and disaster reduction, and ecological protection. As a key component, radar water level gauges employ the microwave ranging principle, achieving non-contact water level monitoring through the transmission and reception of electromagnetic waves, making them suitable for long-term unattended monitoring scenarios in outdoor rivers.

[0003] As shown in the reference case "A Radar Level Gauge" announcement number "CN211783739U", this radar level gauge can change the position of the screw by rotating the nut, thereby changing the installation height of the radar level gauge body. By adjusting the outer and inner tubes, the installation position of the radar level gauge can be changed, thus enabling the equipment to be installed according to the needs of use and expanding the scope of application.

[0004] Although the above application allows for adjustment of the installation height of the radar level gauge, since radar level gauges are usually installed on the shore and extend towards the water surface, this causes great inconvenience and poses certain safety hazards when staff maintain the components extending towards the water surface. Utility Model Content

[0005] Therefore, it is necessary to provide a river hydrological mapping device to address the problem of inconvenient maintenance of radar water level gauges.

[0006] A river hydrological mapping device includes: a mounting base and a column mounted on the surface of the mounting base, wherein a radar sensor is disposed on the top of the column.

[0007] The adjustment mechanism includes a rotating component disposed below the mounting base, a height adjustment rod disposed inside the column, a positioning rod fixedly connected to the surface of the height adjustment rod, and a length adjustment rod disposed inside the positioning rod.

[0008] In one embodiment, the rotating assembly includes a base disposed below the mounting base, a rotating shaft fixedly connected to the lower surface of the mounting base, and the bottom end of the rotating shaft being rotatably connected to the inner wall of the base.

[0009] In one embodiment, a worm gear is fixedly connected to the surface of the rotating shaft, a worm is provided above the base, the worm meshes with the worm gear, one end of the worm is rotatably connected to the base, a first servo motor is mounted on the surface of the base, and the drive end of the first servo motor is fixedly connected to the other end of the worm.

[0010] In one embodiment, the height adjustment rod is slidably connected to the inner wall of the column, and an electric push rod is provided between the bottom end of the height adjustment rod and the inner bottom wall of the column.

[0011] In one embodiment, the length adjusting rod is slidably connected to the inner wall of the positioning rod, and the radar sensor is disposed at one end of the length adjusting rod extending out of the positioning rod.

[0012] In one embodiment, a fixing block is fixedly connected to the inner wall of the positioning rod, and a second servo motor is provided at one end of the inner wall of the positioning rod near the height adjustment rod.

[0013] In one embodiment, a threaded rod is provided between the fixed block and the second servo motor. One end of the threaded rod is fixedly connected to the drive end of the second servo motor, and the other end of the threaded rod is rotatably connected to the fixed block. Beneficial effects

[0014] 1. By incorporating a rotating component, the radar level gauge can rotate flexibly, improving the convenience and safety of maintenance for personnel.

[0028] The following is combined with Figures 1-4 This invention describes a river hydrological mapping device.

[0029] In one embodiment, a river hydrological mapping device includes: a mounting base 100 and a column 200 mounted on the surface of the mounting base 100, with a radar sensor 300 disposed above the column 200.

[0030] The adjustment mechanism 400 includes a rotating component 410 disposed below the mounting base 100, a height adjustment rod 420 disposed inside the column 200, a positioning rod 430 fixedly connected to the surface of the height adjustment rod 420, and a length adjustment rod 431 disposed inside the positioning rod 430.

[0031] This device also includes a signal processing unit, a display, and a control system. During operation, the radar sensor 300 measures the water level by emitting high-frequency microwave signals and receiving signals reflected from the water surface. The time difference of the reflected waves is proportional to the distance to the water level, thus obtaining accurate water level data. The signal processing unit processes and converts the received reflected signals to calculate the actual water level, while the control system manages and displays the entire process.

[0032] like Figure 1 and Figure 4As shown, the rotating assembly 410 includes a base 411 disposed below the mounting base 100. A rotating shaft 412 is fixedly connected to the lower surface of the mounting base 100, and the bottom end of the rotating shaft 412 is rotatably connected to the inner wall of the base 411. A worm gear 413 is fixedly connected to the surface of the rotating shaft 412. A worm 414 is disposed above the base 411, and the worm 414 meshes with the worm gear 413. One end of the worm 414 is rotatably connected to the base 411. A first servo motor 415 is mounted on the surface of the base 411, and the drive end of the first servo motor 415 is fixedly connected to the other end of the worm 414.

[0033] In this embodiment, the surface of the base 411 is provided with two limiting blocks, and the worm gear 414 is disposed between the two limiting blocks. One end of the worm gear 414 is rotatably connected to the surface of one of the limiting blocks, while the other end of the worm gear 414 passes through the other limiting block and is connected to the first servo motor 415 via a coupling. The first servo motor 415 is fixedly connected to the surface of the limiting block. Meanwhile, the rotating components 410 are all enclosed by a protective cover disposed between the base 411 and the mounting base 100 to provide protection. The column 200 is mounted on the surface of the mounting base 100 via a mounting component. When installing this device, the base 411 can be installed in a preset position first, and then the column 200 can be installed on top of the mounting base 100. The electric push rod 421, the first servo motor 415, and the second servo motor 436 in this device can all be started manually or via a PLC controller.

[0034] The rotating components 410 of this device are all located below the mounting base 100 and will not interfere with the movement of the components above the mounting base 100. This device shortens the column 200 and sets a height adjustment rod 420 on the inner wall of the column 200 so that when the height adjustment rod 420 rises to its limit distance, it is the same as the conventional column 200. At the same time, the height adjustment rod 420 is an insert sliding type. In order to reduce the influence of external impurities on the sliding process, a sealing ring is set at the connection between the column 200 and the height adjustment rod 420. This device uses a threaded rod 432 to cooperate with a threaded block 433 and a drive rod 434 on the threaded block 433 to drive the length adjustment rod 431 to extend and retract within the positioning rod 430 to adjust the position of the radar sensor 300 above the water surface. This device is located inside the positioning rod 430 and has no part exposed to the outside world, so external impurities will not interfere with the threaded rod 432. In summary, the adjustment mechanism 400 of this device will not affect the normal operation of the radar sensor 300.

[0035] like Figure 1 , Figure 2 and Figure 3As shown, the height adjustment rod 420 is slidably connected to the inner wall of the column 200, and an electric push rod 421 is provided between the bottom end of the height adjustment rod 420 and the inner bottom wall of the column 200. The length adjustment rod 431 is slidably connected to the inner wall of the positioning rod 430, and the radar sensor 300 is provided at one end of the length adjustment rod 431 extending out of the positioning rod 430. A fixing block 435 is fixedly connected to the inner wall of the positioning rod 430, and a second servo motor 436 is provided at one end of the inner wall of the positioning rod 430 near the height adjustment rod 420. A threaded rod 432 is provided between the fixing block 435 and the second servo motor 436, one end of the threaded rod 432 is fixedly connected to the drive end of the second servo motor 436, and the other end of the threaded rod 432 is rotatably connected to the fixing block 435.

[0036] In this embodiment, when adjusting the height, the electric push rod 421 pushes the height adjustment rod 420 upward. The height adjustment rod 420 is hollow inside. The top of the drive end of the electric push rod 421 is connected to the inner top wall of the height adjustment rod 420. When the electric push rod 421 pushes the height adjustment rod 420, the outer wall of the height adjustment rod 420 slides on the inner wall of the column 200. During this process, the drive part of the electric push rod 421 is not exposed.

[0037] Working principle: Install the base 411 of this device into the ground and keep the upper surface of the base 411 above the ground, and then adjust the device according to the state of the river.

[0038] First, start the electric push rod 421 to push the height adjustment rod 420 upward along the inner wall of the column 200, thereby adjusting the height of the radar sensor 300 above the water surface. Then, start the second servo motor 436, which drives the threaded rod 432 to rotate. The threaded block 433 moves along with the drive block, and the moving block pushes the length adjustment rod 431 to extend outward of the positioning rod 430, thereby adjusting the height of the radar sensor 300 above the water surface.

[0039] When it is necessary to fine-tune the position of the radar sensor 300, the first servo motor 415 can be started. The first servo motor 415 drives the worm gear 414 to rotate, the worm gear 414 drives the worm wheel 413 to rotate, and the worm wheel 413 will drive the rotating shaft 412 to rotate along the base 411 when rotating. At the same time, the length adjustment rod 431 is used to adjust the position of the radar sensor 300.

[0040] When maintenance is required, the position of the height adjustment rod 420 can be adjusted downward by the electric push rod 421, and then the positioning rod 430 and the radar sensor 300 can be rotated to the top of the riverbank by the rotating assembly 410, making the maintenance process safer and more convenient for the staff.

[0041] It should be noted that the threaded rod 432, worm gear 413, worm 414, electric actuator 421, first servo motor 415, and second servo motor 436 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the electric actuator 421, first servo motor 415, and second servo motor 436 can be powered by the built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
