[0024] In this embodiment, the setting of the mobile measuring component 7 can firstly adjust the position of the cross slider 74 in the inner wall of the cross groove 71 according to different river conditions, and then adjust the lifting measuring tube 710 to a closer position in the water, and monitor the changes in water level in real time through the electronic sensing scale 711, and feed back the data to the main controller 4 in real time for summary.

[0025] Specifically, the power shaft of the servo motor 72 passes through the L-shaped movable frame 5 through a bearing and is fixedly connected to the left end of the driving screw rod 73. The front inner wall of the cross slider 74 is slidably connected to the outer wall of the positioning rod 75. The rear inner wall of the cross slider 74 is threadedly connected to the outer wall of the driving screw rod 73. An inclination sensor 78 is fixedly installed on the rear of the top wall of the lifting seat 77.

[0026] In this embodiment, the servo motor 72 works through an external power supply connection and drives the driving screw 73 to rotate, so that the cross slider 74 slides in the inner wall of the cross groove 71. At the same time, the lifting seat 77 drives the inclination sensor 78 to move when it moves up and down. The inclination sensor 78 works in real time to monitor the horizontal position of the lifting measuring cylinder 710.

[0027] Specifically, the outer walls of the lifting and measuring cylinder 710 and the sealing seat 713 are hingedly installed with the support assembly 8, the inner wall of the sealing seat 713 is slidably connected with the outer wall of the pressure measuring assembly 6, the bottom end of the pressure measuring assembly 6 passes through the lifting seat 77 and the closing seat 79 in sequence and is connected with the lifting and measuring cylinder 710, and the inner wall of the pressure measuring assembly 6 is slidably connected with the inner wall of the lifting and measuring cylinder 710.

[0028] In this embodiment, after the lifting measuring tube 710 enters the water, it drives the electronic induction scale 711 to measure the water depth of the river.

[0029] Specifically, a mounting groove 714 is provided at the bottom end of the pressure measuring assembly 6 , and an inductive identifier 715 is installed on the inner wall of the mounting groove 714 .

[0030] In this embodiment, the setting of the inductive identifier 715 enables timely feedback to stop the descending of the lifting measuring cylinder 710 after the measuring column 68 contacts the silt.

[0031] Specifically, the pressure measuring assembly 6 includes an inflator 61, which is fixedly mounted on the top of the left side wall of the L-shaped movable frame 5. The air inlet of the inflator 61 is connected to an air intake pipe 62. The air intake pipe 62 is "L"-shaped. The bottom end of the air intake pipe 62 passes through the L-shaped movable frame 5 through a leak-proof rubber sleeve and extends to the inner side of the L-shaped movable frame 5.

[0032] In this embodiment, the operation of the charging machine 61 is controlled by the main controller 4, and air is drawn from the outside through the air intake pipe 62 for transportation.

[0033] Specifically, the stamping port of the inflator 61 is connected to a discharge movable pipe 63 , and after passing through the top of the L-shaped movable frame 5 , the discharge movable pipe 63 passes through the lifting seat 77 and the closing seat 79 in sequence through the leak-proof rubber sleeve and is connected to the lifting measuring cylinder 710 .

[0034] In this embodiment, the charging machine 61 conveys the gas through the discharge movable pipe 63 into the cavity formed by the closing seat 79 and the lifting and measuring cylinder 710.

[0035] Specifically, a slide seat 64 is slidably installed on the inner wall of the lifting measuring cylinder 710, an air pressure sensor 66 is installed on the top wall of the slide seat 64, a square piston 65 is fixedly installed on the bottom of the slide seat 64, a distance sensor 67 is installed on the bottom of the square piston 65, a measuring column 68 is fixedly installed on the bottom of the square piston 65, the outer wall of the bottom of the measuring column 68 is slidably connected to the inner wall of the sealing seat 713, an installation groove 714 is provided at the bottom of the measuring column 68, the bottom wall of the measuring column 68 is level with the induction identifier 715, and the bottom end of the measuring column 68 is level with the bottom wall of the support assembly 8.

[0036] In this embodiment, the slide 64 and the top of the square piston 65 will form a sealed cavity with the lifting measuring cylinder 710. When external gas enters this sealed cavity, the square piston 65 and the slide 64 are driven by air pressure to slide downward along the inner wall of the lifting measuring cylinder 710, thereby pushing the measuring column 68 through the sealing seat 713 and into the sludge.

[0037] Specifically, the support assembly 8 includes two waterproof electric push rods 81, which are arranged symmetrically on the left and right. The adjacent ends of the two waterproof electric push rods 81 are hingedly installed on the outer wall of the lifting and measuring tube 710. The movable ends of the two waterproof electric push rods 81 are hingedly installed with support plates 82, and the adjacent sides of the bottoms of the two support plates 82 are hingedly installed on the outer wall of the sealing seat 713 through a hinge seat 83.

[0038] In this embodiment, the two support plates 82 are pushed by the waterproof electric push rod 81, so that the support plates 82 can increase the supporting stability of the bottom of the lifting measuring tube 710. When the lifting measuring tube 710 is measuring underwater, it has a good stabilizing effect and can reduce the impact of water flow on the lifting measuring tube 710 to a greater extent.

[0039] Specifically, the bottom walls of the two hinged seats 83 are fixedly mounted with limit plates 84 , and the bottoms of the two limit plates 84 are level with the bottom end of the measuring column 68 .

[0040] In this embodiment, the setting of the limit plate 84 prevents the support plate 82 from rotating too quickly and entering the sludge, and has a limiting effect on the support plate 82.

[0041] Specifically, universal wheels 2 are rotatably installed at the four corners of the bottom wall of the mobile platform 1, and several universal wheels 2 are installed with fastening brakes. The main controller 4 is electrically connected to the flow rate meter 9, the servo motor 72, the lifting push rod 76, the electronic induction scale 711, the inclination sensor 78, the induction identifier 715, the inflator 61, the air pressure sensor 66, the distance sensor 67 and the waterproof electric push rod 81.

[0042] In this embodiment, the provision of the universal wheels 2 facilitates the overall movement of the mobile platform 1 and the entire device, while the main controller 4 controls the electronic control components of the entire device to work in coordination, thereby improving the overall measurement efficiency.

[0043] Working principle of the present invention: First, the flow meter 9, servo motor 72, lifting push rod 76, electronic induction scale 711, inclination sensor 78, induction identifier 715, charging machine 61, air pressure sensor 66, distance sensor 67 and waterproof electric push rod 81 are electrically connected through the external mobile power supply and the main controller 4. Before starting work, the L-shaped movable frame 5 is first moved to drive the counterweight block 3 and the mobile platform 1 to move, and the mobile platform 1 drives the universal wheel 2 to move to the flat area beside the river, and the fastening brake on the universal wheel 2 is locked to prevent the entire device from moving during measurement. The counterweight block 3 mainly has the function of counterweight to increase the overall stability of the mobile platform 1. When the formal work starts, the driving screw 73 is first driven by the servo motor 72 to start Rotate. When the driving screw rod 73 rotates, it will drive the cross slider 74 screwed thereto to start linear movement along the outer wall of the driving screw rod 73 in the inner wall of the cross groove 71 toward the position of the river channel. When the cross slider 74 slides in the inner wall of the cross groove 71, it will simultaneously slide along the outer wall of the positioning rod 75, thereby improving the stability of the cross slider 74 during movement and preventing it from deviating. When the cross slider 74 moves, it will drive the lifting push rod 76, the lifting seat 77, the closing seat 79, the lifting measuring tube 710 and the pressurizing measuring assembly 6 to move synchronously toward a position close to the river channel, and then start measuring the water depth of the river channel. The lifting push rod 76 pushes the lifting seat 77 and the closing seat 79 to move downward, and at the same time, the inclination sensor 78 starts working when the lifting seat 77 descends. , to detect whether the lifting seat 77 maintains a horizontal descending posture, to prevent the lifting seat 77 from being tilted when descending, and the electronic sensing scale 711 from having errors in subsequent measurements, the closing seat 79 then drives the conical cylinder 712, the sealing seat 713 and the electronic sensing scale 711 to extend into the water, and when the electronic sensing scale 711 enters the water, it senses the change in water level and feeds back the water depth data to the main controller 4, and the lifting measuring cylinder 710 will drive the sensing identifier 715 installed at the bottom of the measuring column 68 to descend when it descends, and when the sensing identifier 715 contacts the silt at the bottom of the river channel when it descends, it feeds back the data to the main controller 4, and the main controller 4 immediately controls the lifting push rod 76 to stop descending, and the lifting measuring cylinder 71 0 will drive the flow meter 9 into the water when it descends. The flow meter 9 will measure the speed of the river water flow and return the flow rate to the main controller 4 and record it. When the river depth and water flow speed are measured, the waterproof electric push rod 81 is controlled by the main controller 4 to start working. The movable end of the waterproof electric push rod 81 pushes the support plate 82 to start rotating with the hinge seat 83 as the center. After rotating a certain angle, the support plate 82 contacts the inner bottom wall of the limit plate 84, so that the support plate 82 and the limit plate 84 maintain a horizontal state, and provide a larger bottom area support force with the lifting measuring cylinder 710, and then the air is pumped from the outside through the air inlet pipe 62 through the charging machine 61, and injected into the interior of the lifting measuring cylinder 710 through the exhaust movable pipe 63.External gas enters the sealed cavity formed between the slide 64, the square piston 65 and the lifting measuring cylinder 710. The pressure inside the sealed cavity gradually increases and the pressure change is monitored in real time by the air pressure sensor 66. At the same time, the slide 64 and the square piston 65 slide downward along the inner wall of the lifting measuring cylinder 710 and drive the measuring column 68 to move from the sealing seat 713 into the silt. The distance sensor 67 monitors the distance change from the sealing seat 713, and then feeds back the data to the master controller 4 in real time for unified summary. When the data change monitored by the distance sensor 67 gradually decreases, the master controller 4 controls the compressor 61 to stop working, and returns the nearest monitoring data of the distance sensor 67 to the master controller 4 and summarizes it. After the master controller 4 completes the data collection, it can obtain the silt depth, river water depth and flow rate of the river channel, and calculate the river water depth and river channel width to obtain the cross-sectional area of ​​the river water, thereby completing the measurement of the hydrological characteristics of the river channel.
