[0028] Mounting blocks 101 are installed on the upper end surfaces of both ends of riverbank 1, with a fixed frame 2 installed between them. Fixed frame 2 is erected above the measured water area. Fixed rod 3 is fixedly mounted inside fixed frame 2, and the outer wall of fixed rod 3 is slidably connected to slide frame 4. Driven by the slide frame drive assembly, slide frame 4 moves along fixed rod 3. Sensor moving assembly 7 is fixedly mounted on the bottom of slide frame 4. Sensor moving assembly 7 includes mounting frame 701, with angle controller 8 mounted on its upper end surface.

[0029] A radar water level meter 9 and an electric wave current meter 901 facing the water surface of the measurement water area are installed below the sensor moving assembly 7.

[0030] The slide frame drive assembly is used to drive the slide frame 4 to move along the fixed rod 3, thereby adjusting the position of the slide frame 4 and further adjusting the position of the sensor moving assembly 7. As a specific structure, the slide frame drive assembly includes a first motor 401, a rotating shaft 402, a gear 403 and a rack 301;

[0031] The upper end surface of the fixed rod 3 is fixedly mounted with a rack 301;

[0032] The outer wall of the sliding frame 4 is mounted with a first motor 401 via a bracket. The output end of the first motor 401 passes through the front end surface of the sliding frame 4 and is mounted with a rotating shaft 402. The other end of the rotating shaft 402 is mounted with a gear 403. The first motor 401 drives the gear 403 to rotate via the rotating shaft 402. The outer wall of the gear 403 is engaged with the rack 301.

[0033] The bottom end surface of the fixed rod 3 is mounted with two toothed plates 5 that fit snugly together. The front and rear end surfaces of the sliding frame 4 are both mounted with fixed plates 6, with the outer side wall of one of the fixed plates 6 being mounted with an ultrasonic radar predictive scanning ranging device 501. A screw 602 with oppositely arranged threads at both ends is mounted between the two fixed plates 6. Two sliders 603 are movably sleeved on the outer side wall of the screw 602. The upper end surfaces of the two sliders 603 are both mounted with positioning clamps 604 located on the side away from the two toothed plates 5. The mounting bracket 701 is mounted on the bottom of the two fixed plates 6. A second motor 601 is mounted on the outer side wall of one of the fixed plates 6. The output end of the second motor 601 passes through the fixed plate 6 and is connected to the screw 602, which is used to drive the screw 602 to rotate. By starting the second motor 601, the rotation of the screw 602 can drive the two sliders 603 to move simultaneously.

[0034] In this embodiment: when in use, the radar water level meter 9 is mainly used to measure the height of the water level by transmitting and receiving microwave signals to measure the height of the water surface. The radio wave current meter 901 is mainly used to measure the speed of the water flow by transmitting and receiving radio wave signals to calculate the speed of the water flow. The ultrasonic radar prediction scanning ranging device 501 can scan the cross section of the river bank 1, determine the change status of the cross section, and transmit the detected data to the computer via wireless. Then, through the computer or remote control, the first motor 401 is started, so that the rotating shaft 402 drives the gear 403 to rotate, prompting the gear 403 to move along the rack 301, thereby causing the slide frame 4 to move and drive the sensor moving component 7 moves, and the position of the sensor moving component 7 can be adjusted. By making the screw 602 drive the two sliders 603 to move, the two sliders 603 drive the two positioning clamps 604 to move and clamp the two tooth plates 5, thereby locking the position of the slide frame 4 and the sensor moving component 7, so as to automatically adjust the position of the radar water level meter 9 and the radio wave current meter 901, and achieve the effect of automatically adjusting the measurement position, making the position adjustment flexible, remote control operation, low cost, and high reliability. By making the ultrasonic radar predictive scanning and ranging equipment 501 scan the detection section within the set period, the section change condition can be judged with high efficiency, accuracy and reliability.

[0035] As a technical optimization solution of the present invention, both the front and rear end surfaces of the fixing rod 3 are provided with sliding grooves 302 that are slidably connected to the sliding frame 4 .

[0036] In this embodiment, by providing the sliding groove 302 , when the sliding frame 4 moves, the sliding groove 302 can limit the moving direction of the sliding frame 4 , so that the sliding frame 4 can move stably.

[0037] As a technical optimization solution of the present invention, a sliding rod 6031 fixedly installed between the two fixing plates 6 is movably installed through the outer side walls of the two sliding blocks 603 .

[0038] In this embodiment, by providing a sliding rod 6031 , when the two sliders 603 move, they can move along the sliding rod 6031 , thereby allowing the two sliders 603 to move stably.

[0039] As a technical optimization solution of the present invention, guide rail end sensors 201 located below the fixing rod 3 are installed on both the left and right side walls inside the fixing frame 2 .

[0040] In this embodiment, the guide rail end sensor 201 is provided to facilitate detection of the moving position of the sensor moving assembly 7 .

[0041] As a technical optimization solution of the present invention, the teeth of the two tooth plates 5 are located on the sides that are relatively far away.

[0042] In this embodiment, by arranging the teeth of the two tooth plates 5 to be located on the relatively far side, the friction between the positioning clamping plate 604 and the tooth plate 5 can be increased, making it easier for the two positioning clamping plates 604 to clamp the two tooth plates 5, thereby locking the position of the sensor moving component 7.

[0043] Working principle: First, when using the device, connect the device to an external power source and connect it to the computer equipment in the control room through a wireless signal transmitter. When in use, the radar water level meter 9 is mainly used to measure the height of the water level by transmitting and receiving microwave signals to measure the height of the water surface. The radio wave current meter 901 is mainly used to measure the speed of the water flow by transmitting and receiving radio wave signals to calculate the speed of the water flow. The ultrasonic radar prediction scanning ranging device 501 can scan the section of the river bank 1, determine the change status of the section, and transmit the detected data to the computer wirelessly. Then, through the computer or remote control, start the first motor 401, so that the rotating shaft 402 drives the gear 403 to rotate, prompting the gear 403 to move along the rack 301, thereby causing the slide frame 4 to move and drive the sensor moving component 7 to move. The sensor moving component can be adjusted After adjusting the position of the sensor moving component 7, the second motor 601 is started to make the screw 602 drive the two sliders 603 to move, prompting the two sliders 603 to drive the two positioning clamps 604 to move and clamp the two tooth plates 5, thereby locking the position of the slide frame 4 and the sensor moving component 7, so that the position of the radar water level meter 9 and the radio wave current meter 901 can be automatically adjusted to achieve automatic adjustment of the measurement position, and when the sensor moving component 7 contacts the two guide rail end sensors 201 during movement, it is convenient to detect the moving position of the sensor moving component 7, and by setting the moving cycle of the slide frame 4 and the sensor moving component 7 on the computer, the ultrasonic radar predictive scanning and ranging equipment 501 scans the detection section within the set period to determine the section change condition, which is efficient, accurate and reliable.

[0044] When the utility model is used, the radar water level gauge is mainly used to measure the height of the water level by transmitting and receiving microwave signals to measure the height of the water surface. The radio current meter is mainly used to measure the speed of the water flow by transmitting and receiving radio wave signals to calculate the speed of the water flow. The ultrasonic radar prediction scanning ranging device can scan the river bank section, determine the change of the section, and transmit the detected data to the computer via wireless. Then, through the computer or remote control, the first motor is started, so that the rotating shaft drives the gear to rotate, prompting the gear to move along the rack, thereby causing the slide frame to move and drive the sensor moving assembly to move, and the position of the sensor moving assembly can be adjusted. By driving the two sliders to move, the two sliders drive the two positioning clamps to move and clamp the two tooth plates to fix, thereby locking the position of the slide frame and the sensor moving assembly, thereby achieving the effect of automatically adjusting the position of the radar water level gauge and the radio current meter, and automatically adjusting the measured position, making the position adjustment flexible, remote control operation, reducing costs, and high reliability. In addition, by making the ultrasonic radar prediction scanning ranging device scan the detection section within a set period to determine the change of the section, the efficiency is high, accurate and reliable.

[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be considered within the scope of protection of the present invention.
