A lifting seat 77 is installed. A closing seat 79 is screwed to the bottom wall of the lifting seat 77 via a number of fastening bolts. A lifting measuring cylinder 710 is fixedly installed on the bottom wall of the closing seat 79. An electronic induction scale 711 is installed on the front wall of the lifting measuring cylinder 710. A conical cylinder 712 is fixedly installed on the bottom end of the lifting measuring cylinder 710. The bottom end of the conical cylinder 712 is connected to a sealing seat 713. A mounting groove 714 is opened at the bottom end of the pressure measuring assembly 6. An induction identifier 715 is installed on the inner wall of the mounting groove 714.

[0034] The pressure measurement 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 inside of the L-shaped movable frame 5.

[0035] The punching port of the inflator 61 is connected to a discharge movable pipe 63, which passes through the top of the L-shaped movable frame 5 and then passes through the leak-proof rubber sleeve to penetrate the lifting seat 77 and the closing seat 79 and is connected to the lifting measuring cylinder 710;

[0036] A slide 64 is slidably mounted on the inner wall of the lifting measuring cylinder 710, an air pressure sensor 66 is mounted on the top wall of the slide 64, a square piston 65 is fixedly mounted on the bottom of the slide 64, and a distance sensor 67 is mounted on the bottom of the square piston 65;

[0037] A measuring column 68 is fixedly installed at 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. A mounting 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.

[0038] In this embodiment, the setting of the mobile measuring assembly 7 can firstly adjust the position of the cross slide 74 in the inner wall of the cross groove 71 according to different river conditions, thereby adjusting the lowering position of the measuring cylinder 710 to a higher level of water entry, and monitor the changes in water level in real time through the electronic sensing scale 711, and feed the data back to the main controller 4 in real time for aggregation;

[0039] The setting of the induction identifier 715 enables timely feedback to stop the descending of the lifting measuring cylinder 710 when the measuring column 68 contacts the silt;

[0040] The inflator 61 is controlled by the main controller 4 and is transported by drawing air from the outside through the air inlet pipe 62. The inflator 61 will discharge the transported gas through the exhaust movable pipe 63 into the cavity formed by the closing seat 79 and the lifting measuring cylinder 710. The slide 64 and the top of the square piston 65 will form a sealed cavity with the lifting measuring cylinder 710. When the external gas enters this sealed cavity, the square piston 65 and the slide 64 are driven by the 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 into the sludge.

[0041] Specifically, the power shaft of the servo motor 72 passes through the L-shaped movable frame 5 and is fixedly connected to the left end of the driving screw rod 73 through a bearing. The front inner wall of the cross slider 74 is slidingly 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.

[0042] 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 slot 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.

[0043] Specifically, the outer walls of the lifting 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 slidingly 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 measuring cylinder 710, and the inner wall of the pressure measuring assembly 6 is slidingly connected with the inner wall of the lifting measuring cylinder 710.

[0044] 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.

[0045] 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 measuring cylinder 710, and the movable ends of the two waterproof electric push rods 81 are hingedly installed with support plates 82. The adjacent side of the bottom of the two support plates 82 is hingedly installed on the outer wall of the sealing seat 713 through a hinge seat 83.

[0046] 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 support stability of the bottom of the lifting measuring tube 710. When the lifting measuring tube 710 is measuring at the bottom of the water, it has a good stabilizing effect and can reduce the impact of water flow on the lifting measuring tube 710 to a greater extent.

[0047] 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 .

[0048] In this embodiment, the setting of the limit plate 84 prevents the support plate 82 from rotating too quickly and entering the mud, and has a limiting effect on the support plate 82.

[0049] 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 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.

[0050] In this embodiment, the provision of the universal wheels 2 facilitates the overall movement of the mobile platform 1 and the entire device. At the same time, the main controller 4 controls the electronic control components of the entire device to work in coordination, thereby improving the overall measurement efficiency.

[0051] The working principle of the present invention is as follows: first, the flow meter 9, servo motor 72, lifting push rod 76, electronic induction scale 711, inclination sensor 78, induction identifier 715, inflator 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. 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 begins, the driving screw 73 is first driven by the servo motor 72 to start When the driving screw rod 73 rotates, it drives 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 simultaneously slides along the outer wall of the positioning rod 75, thereby improving the stability of the cross slider 74 during movement and preventing it from deflecting. When the cross slider 74 moves, it drives the lifting push rod 76, the lifting seat 77, the closing seat 79, the lifting measuring cylinder 710 and the pressure measuring assembly 6 to move synchronously toward a position close to the river channel, and then starts to measure the water depth of the river channel. The lifting push rod 76 pushes the lifting seat 77 and the closing seat 79 downward, and at the same time, the inclination sensor 78 starts working when the lifting seat 77 descends. , implement detection whether the lifting seat 77 maintains a horizontal descending posture, prevent the lifting seat 77 from tilting when descending, and the electronic sensing scale 711 from making errors in subsequent measurements. The closing seat 79 then drives the conical cylinder 712, the sealing seat 713 and the electronic sensing scale 711 into the water. 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. When the lifting measuring cylinder 710 descends, it drives the inductive identifier 715 installed at the bottom of the measuring column 68 to descend. When the inductive identifier 715 contacts the silt at the bottom of the river during descent, 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 When the water level drops, the flow meter 9 is driven into the water. The flow meter 9 measures the speed of the river flow and returns the speed to the main controller 4 and records it. After the river depth and water flow speed are measured, the main controller 4 controls the waterproof electric push rod 81 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. Then, the air is extracted from the outside through the air inlet pipe 62 by the charging machine 61, and is injected into the interior of the lifting measuring cylinder 710 through the exhaust movable pipe 63.External air 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 from the sealing seat 713 into the silt. The distance sensor 67 monitors the distance change from the sealing seat 713 and then feeds the data back to the main controller 4 in real time for unified summary. When the data change monitored by the distance sensor 67 gradually decreases, the main controller 4 controls the charging machine 61 to stop working and returns the most recent monitoring data of the distance sensor 67 to the main controller 4 for unified summary. After the main 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 river channel hydrological characteristics.
