[0020] The following further describes specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the descriptions of these embodiments are intended to aid understanding of the present invention and do not constitute limitations on the present invention. Furthermore, the technical features involved in the various embodiments of the present invention described below may be combined with one another as long as they do not conflict with one another.

[0021] refer to Figure 1 A sailing ADCP cableway current measurement catamaran is mainly composed of a central main cabin and two hulls 3 on both sides. The main cabin is equipped with a current measurement device with a device base 1, a battery compartment, a controller compartment, and a lifting mechanism 2 for adjusting the device base 1. The device base 1 consists of an upper disc 11 and a lower disc 12, as well as a handle on the upper disc. Figure 2 As shown, the ADCP mainframe is fixed beneath the lower disc 12, while the upper disc 11 can be placed on the ADCP lifting mechanism 2 for securement. A gap is left between the upper and lower discs 11, which are bolted together. The battery compartment contains lithium batteries. The controller compartment consists of a data acquisition and communication controller, a photovoltaic panel controller, and a reduction motor. A metal frame 31 is fixed to the left and right hulls 3. The frame 31 is positioned perpendicular to the two hulls 3, with a handle on each side and four support legs at its base, allowing the entire system to be placed on the ground and protecting the catamaran. A main cabin cover 311 is hinged to the front of the frame 31 to provide protection. The outer cabins of the left and right hulls 3 are welded from sheet metal, and foam panels are installed inside to provide waterproofing. Suspension rings are installed at the front and rear ends of both hulls 3, and the rings are symmetrically arranged to ensure the cableway current measurement catamaran maintains a balanced state. Exhaust valves are installed at the front and rear of both hulls 3, and the exhaust valves are installed symmetrically. A water level monitoring device that can detect whether the water level has been reached is installed on the side of the right hull. The water level monitoring device consists of a metal bracket 321, a plastic bracket 322, and a detection wire. The metal bracket 321 is installed on the hull at a certain distance from the bottom of the hull. The distance depends on the height to be detected. The plastic bracket 322 is installed on the metal bracket 321. The detection wire is installed on the plastic bracket 322 via a cold-pressed terminal. When the water level reaches the position to be detected, the detection wire is immersed in the water, forming a closed loop with the water, which can be detected by the data acquisition and communication controller. A photoelectric switch is installed on one side of the middle rectangular platform 22. When the ADCP device connected to the middle rectangular platform reaches the required position, it can be detected by the photoelectric switch and transmitted to the controller, thereby controlling the vertical lifting range of the lifting mechanism.

[0022] The tail of the hull 3 is fixed with a stern fin 33, which can keep the bow direction of the catamaran consistent with the direction of the water flow, avoiding the problem of irregular rotation of the catamaran in the water flow. The catamaran runs stably during flow measurement, improving the flow measurement accuracy of the underway ADCP.

[0023] refer to Figure 3 The ADCP lifting mechanism 2 consists of an upper rectangular platform 21, a middle rectangular platform 22, a lower rectangular platform 23, a pulley mechanism, a screw mechanism, and a guide shaft. The upper rectangular platform 21 and the lower rectangular platform 23 are used to connect the screw mechanism and the guide shaft, and a pulley mechanism is installed at the end of the guide shaft and the screw mechanism. The middle rectangular platform 22 can fix the equipment base 1. Four fixed blocks 221 for fixing the equipment base 1 are installed on the middle rectangular platform 22. The fixed blocks are L-shaped, and two of the fixed blocks are equipped with indexing pins to fix the equipment base 1. Four guide shafts distributed in a rectangular shape are arranged between the lower surface of the upper rectangular platform 21 and the upper surface of the lower rectangular platform 23. The axes of the guide shafts are arranged vertically. The centers corresponding to the rectangular distribution lines of the guide shafts are located on the same vertical axis as the centers of the upper rectangular platform 21, the middle rectangular platform 22, and the lower rectangular platform 23. The sliders of the four guide shafts are connected to the middle rectangular platform 22. Screw mechanisms are installed at both ends of the lifting mechanism 2, and pulley mechanisms are installed at the ends of the two screw mechanisms. The pulley mechanisms are driven by a reduction motor, which in turn drives the screw mechanisms to lift and lower the central rectangular platform 22.

[0024] refer to Figure 4 The main cabin cover 311 is embedded with photovoltaic panels 312, warning lights 313 and wireless communication antennas 314. The photovoltaic panels 312 can provide energy for the battery. The warning lights 313 can emit flashing red light at night to indicate the current position of the gondola to avoid accidental collision with other ships. The wireless communication antenna 314 can realize long-distance and stable transmission of flow measurement business data, catamaran status information, ADCP control instructions, etc., ensuring stable and reliable wireless communication data interaction.

[0025] refer to Figure 5The control system for the underway ADCP current measurement catamaran primarily consists of a mainframe ADCP, a lifting mechanism 2, photovoltaic panels 312, a photovoltaic panel controller, a battery, a data acquisition and communication controller, an IoT communication module, a photoelectric switch, a reduction motor, a warning light 313, and a water entry detection wire. The data communication and acquisition controller transmits operational data collected by the ADCP, such as flow rate and velocity, as well as status information such as the catamaran's power supply voltage. It also receives control commands for ADCP lift and transmission, and controls the reduction motor's rotation according to these commands. The wireless communication antenna enables stable, long-distance transmission of current measurement data, catamaran status information, and ADCP control commands, ensuring stable and reliable wireless data exchange. The reduction motor rotates to drive the ADCP lifting mechanism to raise and lower the ADCP according to control commands. The photoelectric switch acts as an ADCP lift limiter, effectively limiting the ADCP's lift range. The catamaran water entry detection wire provides timely feedback on the catamaran's entry signal. When the water level exceeds the wire's detectable position, the detection wire immerses in the water, forming a closed loop with the water. The wire's voltage level changes can be detected by the data communication and acquisition controller. The photovoltaic panel controller converts the output voltage of photovoltaic panels 312 to a level acceptable to the battery, continuously supplying energy to the battery and ensuring the catamaran can continue to operate normally even in rainy weather. Warning light 313 flashes red at night to indicate the current position of the gondola and prevent other vessels from accidentally colliding with it.

[0026] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are illustrative and cannot be understood as limitations on the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
