Especially for large rivers such as the Yangtze River, the round-trip distance is long, and there are great limitations in use. There has always been a lack of a device with a reasonable structure, high degree of intelligence, unattended automatic flow measurement, and high flow measurement accuracy to solve the above technical problems.

[0033] See also Figures 1 to 5 This application adopts a structural form in which the main load-bearing cable and the power cable are separately arranged. The load-bearing and driving are divided into different cables, and the detection equipment moves more smoothly. At the same time, a clutch drive connection device is adopted. Compared with the traditional method of driving by cable friction, it avoids cable wear to the greatest extent and extends the service life. In addition, the lead fish holding compartment on the pod detection equipment is equipped with a lead fish flow measurement device, which can be suspended and lifted into the water for hydrological monitoring. The specific structure and principle are as follows:

[0034] A left bank support frame 2 is fixedly installed on the left side of the riverbed 1, and a right bank support frame 3 is fixedly installed on the right side of the riverbed 1. The left bank support frame 2 and the right bank support frame 3 are made of steel structure or reinforced concrete structure, and the height of the installation is relatively high, which is much higher than the navigation height of the river channel or reservoir. The left bank support frame 2 and the right bank support frame 3 not only play the role of erecting the cableway, but also have the functions of power supply and communication. A hydrological main cable 4 is connected between the left bank support frame 2 and the right bank support frame 3. Cable mounting frames 6 are respectively installed on the left bank support frame 2 and the right bank support frame 3. The hydrological main cable 4 is installed on the cable mounting frame 6 through a main cable fixing member 8. The main cable fixing member 8 is a structure such as a steel cable clamp, an anchor or a wire rope cable fixing wheel.

[0035] A circular power cable 5 is also provided on the cable mounting frame 6 on the left bank support frame 2 and the right bank support frame 3. The circular power cable 5 is a closed circular cable. A power pulley 9 is installed on one of the cable mounting frames 6 on the left bank support frame 2 and the right bank support frame 3, and a driven pulley 10 is installed on the other cable mounting frame 6. The circular power cable 5 is installed between the power pulley 9 and the driven pulley 10. It is also possible to install power pulleys 9 on both cable mounting frames 6, and the two power pulleys 9 rotate synchronously. The power pulley 9 is coaxially fixed with the output shaft of the servo motor 11, and the servo motor 11 is installed on the cable mounting frame 6. The servo motor 11 drives the power pulley 9 to rotate, thereby driving the circular power cable 5 to operate. The middle straight section of the circular power cable 5 is basically parallel to the hydrological main cable 4. In order to facilitate the adjustment of the tightness of the hydrological main cable 4 and the annular power cable 5 when installing the hydrological main cable 4 and in different seasons, the present application installs a tensioning adjustment member 7 between the cable mounting frame 6 and the support frame on the same side. The tensioning adjustment member 7 is a prestressed adjustment structure composed of bolts and pressure springs. By adjusting the tensioning adjustment member 7, the tightness of the hydrological main cable 4 and the annular power cable 5 can be well adjusted.

[0036] The hydrological main cable 4 is provided with more than two pod detection devices that can move back and forth. The pod detection devices include a traveling frame, a pod shell 23 and other equipment and instruments. When there are two pod detection devices, the corresponding traveling frames are respectively a No. 1 traveling frame 15 and a No. 2 traveling frame 16. A battery 22 is installed on the traveling frame, and a charging connector 21 connected to the battery 22 is provided at the end of the traveling frame. The charging connector 21 is connected to the input end of the battery 22 via a power controller or a transformer. Four or more main cable rollers 17 are installed on the traveling frame. The main cable rollers 17 are distributed in four corners or in a matrix. The main cable rollers 17 are placed on the hydrological main cable 4 to achieve coordination. The hydrological main cable 4 plays a supporting and bearing role. The traveling frame can move back and forth under the rolling of the main cable rollers 17. A pod shell 23 is fixedly arranged below the traveling frame, and can also be suspended and connected to the pod shell 23 via a suspension cable structure. The distance between the traveling frame and the pod shell 23 can be adjusted by adjusting the length of the suspension cable.

[0037] The traveling frame is also equipped with a clutch drive connection device that matches the circular power cable 5. The clutch drive connection device can be remotely controlled to achieve locking and separation with the circular power cable 5. When the clutch drive connection device is locked with the circular power cable 5, the traveling frame and the pod detection equipment will move with the operation of the circular power cable 5; when the clutch drive connection device is separated from the circular power cable 5, the traveling frame and the pod detection equipment will not move with the operation of the circular power cable 5, but will stay at a fixed position to achieve fixed-point hydrological monitoring. The clutch drive connection device can adopt a variety of structural forms, mainly the following two structures:

[0038] Embodiment 1: The clutch-type driving connection device includes a limiting wheel 18, a clamping wheel 19 and an electromagnetic clutch 20.

The lower end of the clamping wheel 19 is installed with an electromagnetic clutch 20 or an electric telescopic rod through the wheel frame. The electromagnetic clutch 20 or the electric telescopic rod can extend upward, thereby driving the clamping wheel 19 to squeeze the strands of the annular power cable 5, so that the limiting wheel 18 and the clamping wheel 19 clamp the annular power cable 5 in the middle, so that when the annular power cable 5 is running, it can drive the traveling frame and the flow measuring device to move together.

[0039] Embodiment 2: The clutch-type drive connection device includes a limiting wheel 18, a clamping block and a clamping device. One or more limiting wheels 18 are installed on the traveling frame.

A clamping block is installed on the clamping device. The clamping block is arranged corresponding to the annular power cable 5, and the annular power cable 5 is located between the limiting wheel 18 and the clamping block.

[0040] In the present application, charging berthing cabins 12 are installed on the left bank support frame 2 and the right bank support frame 3 respectively. The main hydrographic cable 4 and the circular power cable 5 are inserted into the interior of the charging berthing cabin 12. The portion where the main hydrographic cable 4 and the circular power cable 5 are inserted into the charging berthing cabin 12 is provided with an access window 13. The pod detection equipment can enter the charging berthing cabin 12 through the access window 13, enter and dock on the charging berthing cabin 12. Each charging berthing cabin 12 can accommodate one or more pod detection equipment. A charging trigger berthing position 14 is provided inside the charging berthing cabin 12. The charging trigger berthing position 14 is provided corresponding to the charging connection seat on the traveling frame. The pod detection equipment entering the charging berthing cabin 12 can automatically realize the docking between the charging connector 21 and the charging connection seat, and complete autonomous charging.

[0041] The pod power module 24 and the microprocessor 25 are arranged inside the pod shell 23, and the detector 26 is arranged at the bottom of the pod shell 23 for detecting the water surface. A lead fish storage compartment 27 is arranged at the bottom of the inner cavity of the pod shell 23, and a lead fish flow measurement device capable of being suspended and lifted is carried in the pod shell 23.
