[0042] Specifically, the inner left and right sides of the protective sleeve 11 are provided with sliding grooves 201, and the two sliding rods 202 are respectively connected to the inner left and right sides of the protective sleeve 11. When the internal components need to be maintained or operated, the baffle 15 can be pulled, and the sliding rod 202 can slide in the sliding groove 201 to guide the movement of the baffle 15. The top front side of the protective sleeve 11 is fixed with a buckle fixing device 203, and the top of the baffle 15 is provided with a pipe clamp 204. The buckle fixing device 203 clamps the pipe clamp 204 to fix the baffle 15 so that it cannot move.

[0043] Referring to Figure 1 and Figure 2 , the bottom front and back sides of the suspension sleeve 1 are fixedly connected with two hinges 16, and the top of the plurality of hinges 16 is fixedly connected with a suspension plate 17. The suspension plate 17 is opened to increase the suspension area. The front top of the baffle 15 is fixedly connected with a handle 18, and the rear side of the handle 18 is provided with a plurality of grooves 19 to facilitate pulling the baffle 15. The top rear side of the suspension sleeve 1 is fixedly connected with a fixed column 20, and the top of the fixed column 20 is fixedly connected with a circular ring 21 for fixing the position of the water inlet pipe 4.

[0044] Specifically, the bottom front and back sides of the suspension sleeve 1 are fixed with two hinges 16, and the top of the hinge 16 is connected with the suspension plate 17. When the suspension stability needs to be enhanced, the suspension plate 17 can be opened to increase the suspension area.

[0045] Referring to Figure 1 , Figure 3 and Figure 5 , the rear middle part of the suspension sleeve 1 is fixedly connected with a fixed block 22, and the rear side of the fixed block 22 is fixedly connected with a fixed sleeve 23 for fixing the position of the water suction pipe. The top of the plurality of hinges 16 is fixedly connected to the bottom front and back sides of the suspension sleeve 1 at equal intervals. The diameter of the valve sleeve 14 is greater than the diameter of the water outlet pipe 13 to control the water outlet amount of the water outlet pipe 13. The two sides of the sliding rod 202 are symmetrically arranged. The diameter of the sealing pipe 206 is smaller than the diameter of the semicircular groove 205.

[0046] Specifically, the fixed block 22 in the middle of the rear side of the suspension sleeve 1 extends backward to form a fixed sleeve 23, which is used to stabilize the water pumping pipe and prevent it from shaking or shifting in a complex water flow environment, ensuring stable water pumping operation. The top of the plurality of hinges 16 is fixed to the bottom of the suspension sleeve 1 in an equal interval manner, and the connected suspension plate 17 can be expanded as needed to enhance the suspension effect. The diameter of the valve sleeve 14 is larger than that of the water outlet pipe 13, which can accurately control the water outlet amount. The sliding bar 202 cooperates with the sliding groove 201, and the sealing pipe 206 can be tightly embedded in the semicircular groove 205, which can ensure the stable and efficient operation of the instrument in all directions.

[0047] Working principle: when sinking is needed, the water pump 3 on the top left side of the suspension sleeve 1 is started to pump water into the suspension sleeve 1 through the water inlet pipe 4, increasing its weight and making the whole sink. When rising, the water in the suspension sleeve 1 is discharged through the water outlet pipe 13 under the control of the valve sleeve 14, and the weight is reduced to rise, so as to realize automatic adjustment of the suspension height according to the water depth, adapt to different monitoring environments, and use the motor 8 to drive the turbine rotor 9 to rotate. Because the rotation speed of the turbine rotor 9 is proportional to the water flow speed, the magnetic induction counter 7 installed on the front side inside the protection box 5 records the number of revolutions of the turbine rotor 9, and then calculates the water flow speed. The ultrasonic ranging probe 6 on the bottom right side of the suspension sleeve 1 emits ultrasonic pulses at specific time intervals, receives reflected echoes to calculate water depth, and provides more dimensional data for flow speed measurement and water environment analysis. The controller 12 is located inside the protection sleeve 11 at the bottom, receives the data of the ultrasonic ranging probe 6 and the magnetic induction counter 7, quickly processes data by virtue of its support for high-speed data transmission, and filters noise by using advanced algorithms to ensure data accuracy. The baffle 15 on the front side of the protection sleeve 11 forms a protection for the internal elements, so that the instrument can run stably in a complex water environment, and finally provides reliable data for water conservancy engineering flow speed monitoring.

[0048] And, when the baffle 15 is installed in place, the sealing tube 206 is inserted into the semicircular groove 205, forming a tight sealing structure, while ensuring insertability, using the elastic deformation of the material itself to achieve effective filling of the gap, blocking external moisture from entering the inside of the protective sleeve 11, preventing damage to electronic components due to water immersion, ensuring stable operation of the instrument in a humid or underwater environment, the buckle holder 203 holds the tube card 204, and a stable restraining force is applied to the baffle 15 to fix the baffle 15 in a predetermined position, which prevents accidental movement of the baffle 15 due to water flow impact, vibration and other external forces during instrument operation, thereby providing a continuous and stable protective barrier for internal components. When maintenance, repair or replacement of the electronic components inside the protective sleeve 11 is required, pull the baffle 15, and the two sliding bars 202 connected to the baffle 15 will function, the sliding groove 201 provides a precise track for the movement of the sliding bar 202, and the sliding bar 202 slides smoothly in the sliding groove 201, not only ensuring the smoothness of the baffle 15 during movement, but also preventing it from deviating, jamming or tilting during movement, ensuring that the staff can smoothly open the baffle 15 and quickly access the internal components, improving the efficiency and convenience of maintenance work.
